Dongguan haizhun mechanical and Electrical Technology Co., Ltd.: the utility model relates to an accessory of a sewing machine, especially a belt shaking device of a belt conveyor which can avoid the entanglement and knot of rubber belt and elastic belt in the clothing.
Generally, in order to make clothes, such as sportswear, rhythmic clothing, underwear, swimsuits, etc., elastic ribbons such as rubber bands and elastic bands are needed for sewing. Generally, in order to sew such ribbons, it is necessary to use
The belt conveyor (100) shown in Fig. 1 is used to relax the belt in advance and make the belt return to its original state before use, so as to avoid the size error of the clothing due to the elastic recovery effect after the belt is sewn on the clothing and affect the quality of the finished product. However, due to the interlaced entanglement of the ribbons that fall into the box after being loose, there are often entanglements and knots on the way to the belt feeding roller of the belt conveyor. Therefore, the sewing work must be interrupted to eliminate the entanglement of the ribbons, which is the disadvantage of the general belt conveyor.
In order to solve the traditional belt conveyor, such as
The belt conveyor (100) shown in Fig. 1 has the above disadvantages. Generally, in the traditional belt conveyor, the upper layer of the lower section of the belt conveyor (100) shown in Fig. 2 and Fig. 3 is equipped with a buffeting pulley driven by a separate additional motor. The buffeting belt wheel is composed of several buffeting belt rods which are not equidistant from the axle center. When the buffeting belt wheel is rotating, each buffeting belt rod with different distance can produce a shaking effect on the belt.
However, the biggest disadvantages of this traditional tape shaker are: 1. Its structure is complex, so it needs to be driven by a special motor.
2. High cost.
In view of this, the creator of the utility model, after continuous research and innovation, has finally completed the belt shaking device of the belt conveyor of the utility model.
The purpose of the utility model is to provide a belt shaking device of the belt conveyor, so as to eliminate the entanglement and knotting of the belt, so as to make the sewing work of the garment not interrupted, and the structure is simple, the cost is low, and there is no trouble of maintenance.
To achieve the above purpose, the utility model adopts the following technical scheme: a belt shaking device of a belt conveyor, which comprises a connecting arm, an eccentric shaft section of a belt conveyor roller, which is pivoted in a belt conveyor, and is linked with the eccentric shaft section; a rocker arm, which is pivoted in the belt conveyor, is pivoted in the belt conveyor, and the other end is provided with a second connecting part, so as to The first and second pivoting parts of the connecting arm are pivoted, and the buffeting belt rod is connected with a fixed connection part at the side end of the connecting arm, and the end section of the buffeting belt rod is bent to form a hook buckle part to hook and span the belt. When starting to drive the belt conveying roller, the eccentric shaft section is linked with the connecting arm to make the belt shaking rod shake the belt and avoid entanglement and knot of the belt.
The embodiment of the utility model is described in detail as follows in combination with the attached drawings

As shown in Fig. 1 and Fig. 2, the embodiment of the utility model is installed on a belt conveyor (100), including a connecting arm (1), a rocker arm (2) and a belt shaking rod (3); wherein the connecting arm (1) is an eccentric shaft section (101A) of a belt conveying roller (101) pivoted on the belt conveyor (100), and after starting the belt conveying roller (101), the eccentric shaft section (101A) is linked with the connecting arm (1) to swing circularly so that the rear end of the connecting arm (1) is connected and extended The shaking rod (3) of the belt conveyor (100) generates shaking, so as to apply cyclic and continuous shaking to the belt object (102) dropped from the longitudinal direction of the belt reel of the belt conveyor (100), so as to avoid entanglement and knot of the belt object (102).
The belt conveyor (100) disclosed by the utility model is as follows
The structure shown in Figure 1 or other traditional belt conveyor structure is not limited by the utility model, while the traditional structure of the belt conveyor (100) is not included in the application scope of the utility model, so it will not be described in detail.
The belt conveyor (100) disclosed by the utility model at least comprises a belt conveying roller (101), one end of which forms an eccentric shaft section (101A), and an shaft hole (101b) is formed by convex from the eccentric shaft section (101A) according to the shaft axis (101 ') of the belt conveying roller (101'), so as to connect the drive shaft (M1) of a motor (m). If the motor (m) is started, the belt conveying roller (101) is still the same according to the shaft axis of the motor drive shaft (M1) The center rotates, so that the eccentric shaft section (101A) rotates eccentrically, and the linkage connecting arm (1) deflects.
As shown in Fig. 4, the connecting arm (1) is an eccentric shaft section (101A) including a first pivoting part (11) for pivoting the belt conveying roller (101), a second pivoting part (12) is a second connecting part (22) for pivoting the rocker arm (2), and a fixed connecting part (13), which is arranged at the rear side of the connecting arm (1) to fixedly install the buffeting belt rod (3).
The connecting arm (1) disclosed by the utility model can be nested with a bush (s) in the first and second pivoting parts (11, 12) to reduce the friction loss of the first and second pivoting parts (11, 12) and improve the strength of each pivoting part; one end of the shaking band rod (3) is provided with an external thread section (311) and is directly fixed in the fastening part (13) of the connecting arm (1) in an integrated forming way, and the utility model has The fixing method of the buffeting belt rod (3) and the connecting arm (1) is not limited.
