Description

Technical Field

[0001] The utility model relates to rubber band processing equipment, in particular to a material pushing and positioning mechanism used for rubber band processing. Background Art

[0002] The structure of the rubber belt processing equipment designed previously is as shown in the attached Figure 8 As shown, its main structure includes a raw material conveying part 1, a seaming part 2, and a material sorting part 3. The seaming part 2 includes a material pulling part 18, a folding part 19, and a seaming processing part 20.

[0003] In actual use, the raw material conveying member 1 conveys the strip-shaped rubber band raw material to one side of the pulling member 18, the pulling member 18 clamps the end of the rubber band raw material and pulls the rubber band raw material into the folding member 19, and then the cutter in the raw material conveying member 1 cuts the rubber band raw material, and the folding member 19 folds the cut rubber band raw material, and the two ends of the rubber band raw material are aligned with each other. The folding member 19 then transfers the rubber band raw material with the ends aligned to the sewing processing member 20 for sewing. After the sewing is completed, the rubber band has a ring structure. A guide rod 4 is also installed on the folding member 19. After the sewing is completed, the rubber band is sleeved on the outer rod wall of the guide rod 4 and can slide downward along the guide rod 4. The rubber band enters the material sorting member 3 for neat stacking.

[0004] Although the rubber band processing equipment with the above structure has a high efficiency in rubber band processing speed, on the one hand, since the rubber band itself has a certain elasticity, on the other hand, when the rubber band after sewing enters the material sorting piece 3, it is easy to torsionally deform and cannot pass through the material sorting piece 3 for subsequent normal material sorting and arrangement. Utility Model Content

[0005] In view of this, the utility model aims to provide a pusher positioning mechanism for rubber band processing, which can release thrust to the rubber band entering the guide rod, thereby minimizing the probability of accidental torsional deformation of the rubber band.

[0006] In order to solve the above technical problems, the technical solution of the utility model is:

[0007] A material pushing and positioning mechanism for processing rubber bands, comprising a raw material conveying member, a seaming member, a material sorting member, and a material guiding rod, wherein the raw material conveying member conveys the raw material to the seaming member for seaming, and the material guiding rod guides the rubber bands seamed by the seaming member into the material sorting member for material sorting and arrangement;

[0008] It also includes a positioning member, the positioning member includes a telescopic positioning drive source and a telescopic positioning head, the telescopic positioning drive source is used to drive the telescopic positioning head to move toward one side of the guide rod;

[0009] When the elastic band processed by the seaming piece falls onto the material guide rod, the telescopic positioning driving source drives the telescopic positioning head to move, and the telescopic positioning head generates a thrust effect on the elastic band.

[0010] Through the above technical scheme, the elastic band after the seaming of the seam piece is completed will be sleeved on the material guide rod. At this time, after the elastic band is pushed out of the seam piece, the telescopic positioning drive source drives the telescopic positioning head to move toward one side of the material guide rod, and the telescopic positioning drive source generates a thrust on the sewn elastic band, so that the belt surface of the elastic band generates a preliminary abutting force, thereby minimizing the probability of accidental torsional deformation of the elastic band.

[0011] Preferably, the telescopic positioning drive source comprises a telescopic cylinder, and the telescopic positioning head is mounted on a cylinder head of the telescopic cylinder.

[0021] Through the above technical solution, the elastic band after the seam piece is processed is put on the guide rod, and then slides downward along the guide rod and the guide head. When the elastic band moves along the guide head, since the size of the guide head changes from small to large, the entire elastic band will be gradually stretched out to facilitate subsequent material sorting.

The gas ejected from the first air guide hole can blow part of the material away from the outer rod wall of the guide rod, and the gas ejected from the second air guide hole can blow part of the material away from the guide head, thereby effectively reducing the friction between the guide rod, the guide head and the material, the material falls more smoothly, the material is not easy to twist and deform, and the impact on subsequent material sorting is controlled to a minimum.
