Technical Field

[0001] The utility model relates to the technical field of packaging, and specifically, to an automatic feeding packaging machine. Background Art

[0002] A cutting disc belongs to a grinding wheel and is a thin sheet used for cutting ordinary steel, stainless steel metal and non-metallic materials. It uses glass fiber and resin as reinforcing binding materials and has high tensile, impact and bending strength. It is widely used in the production and blanking of ordinary steel, stainless steel metal and non-metallic materials. After the cutting disc is produced, it needs to be packaged. First, a plurality of cutting discs are stacked on a platform. Secondly, a packing film is sleeved on the cutting discs. Then, a hot air gun is used to heat one side of the cutting discs. Finally, by rotating the cutting discs, the packing film is completely heat-shrunk and coated on the cutting discs to package a plurality of cutting discs uniformly, which is convenient for the transportation and placement of the cutting discs.

[0003] In the prior art, when an automatic feeding packaging machine packages cutting discs in batches, a rotating platform drives a plurality of cutting discs to rotate. Due to the lack of limitation on the cutting discs, the cutting discs are prone to relative sliding with the platform, and it is difficult for the cutting discs to rotate synchronously with the platform, resulting in some packing film on the cutting discs not passing through the air outlet of the hot air gun, thereby affecting the heat-sealing effect of the packing film and having a poor packaging effect. Therefore, the utility model proposes an automatic feeding packaging machine. Summary of the Utility Model

[0004] The utility model proposes an automatic feeding packaging machine, which solves the problem that when the automatic feeding packaging machine in the related technology packages cutting discs in batches, the cutting discs are prone to relative sliding with the platform, and it is difficult for the cutting discs to rotate synchronously with the platform, resulting in some packing film on the cutting discs not passing through the air outlet of the hot air gun, affecting the heat-sealing effect of the packing film and having a poor packaging effect.

Detailed implementation mode

[0022] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0023] Embodiment 1

[0024] As Figures 1 to 6 shown, this embodiment proposes an automatic feeding and packaging machine, including a convex platform 1. The upper surface of the convex platform 1 is rotatably connected to an annular platform 11. The upper surface of the convex platform 1 is fixedly connected to a central rod 12. The upper surface of the annular platform 11 is rotatably connected to a plurality of internal gears 13. A hot air gun 14 is arranged on one side of the annular platform 11. The tops of the internal gears 13 are fixedly connected to boxes 2. The tops of the boxes 2 are fixedly connected to placing plates 21. The upper surfaces of the placing plates 21 are fixedly connected to two placing blocks 22. On the inner bottom walls of the boxes 2, two moving blocks 23 and clamping plates 24 are slidably connected. Both ends of the moving block 23 are meshed with the clamping plate 24 through teeth. A first spring 25 is fixedly connected between the two moving blocks 23. A second spring 26 is fixedly connected between the sides of the two clamping plates 24 away from each other and the box 2. The tops of the moving blocks 23 are fixedly connected to a pair of clamping rods 27. Through grooves adapted to the clamping rods 27 are opened on the upper surfaces of the placing plates 21. The tops of the clamping rods 27 penetrate through the through grooves and extend to the outside of the through grooves. The sides of the two moving blocks 23 close to each other are fixedly connected to U-shaped push rods 28. The U-shaped push rods 28 sequentially slide through the side walls of another moving block 23 and the box 2. The sides of the two clamping plates 24 away from each other are fixedly connected to pull rods 29. The horizontal ends of the pull rods 29 slide through the side walls of the box 2.

[0025] A motor box 3 is fixedly connected to the outer side wall of the boss 1. A motor 31 is fixedly connected to the inner bottom wall of the motor box 3. The top of the motor box 3 is rotatably connected to an outer gear 32. The output end of the motor 31 is fixedly connected to the outer gear 32. By arranging the outer gear 32 to be meshed with the inner gear 13, when the motor 31 is started, the motor 31 drives the outer gear 32 and the inner gear 13 to rotate through the output end, so that the inner gear 13 can drive the cutting blade and the packing film to rotate, facilitating the hot air gun 14 to heat the packing film on the cutting blade; Rubber blocks 4 are fixedly connected to the outer side walls of the clamping rods 27. By arranging the rubber blocks 4, the two pairs of clamping rods 27 clamp the cutting blade through the rubber blocks 4, increasing the friction force between the clamping rods 27 and the cutting blade, making the clamping more stable; A T-shaped block 5 is fixedly connected to the outer side wall of the central rod 12. The side of the T-shaped block 5 away from the central rod 12 is arc-shaped. An L-shaped block 51 is fixedly connected to the outer side wall of the boss 1. An extrusion block 52 is fixedly connected to the vertical end of the L-shaped block 51. By arranging the T-shaped block 5 and the extrusion block 52, when the box body 2 drives the two U-shaped push rods 28 to rotate, under the action of the arc surface, both the T-shaped block 5 and the extrusion block 52 can push the two U-shaped push rods 28, so that the two moving blocks 23 slide along the sliding groove 71; Two sliders 7 are fixedly connected to the bottoms of the moving block 23 and the clamping plate 24. A sliding groove 71 adapted to the sliders 7 is formed on the inner bottom wall of the box body 2. The sliders 7 are all slidably connected to the inner side wall of the sliding groove 71. By arranging the sliders 7 to be slidably connected to the sliding groove 71, the moving block 23 and the clamping plate 24 are limited, so that the moving block 23 and the clamping plate 24 always slide along the direction of the sliding groove 71; Vertical rods 8 are fixedly connected to the tops of the placing blocks 22. By arranging the vertical rods 8, it is convenient to place a plurality of cutting blades on the placing blocks 22 along the vertical rods 8, so that the tops of the two pairs of clamping rods 27 penetrate through the cutting blades through the through holes on the cutting blades;

[0026] In this embodiment, by stacking multiple cutting discs on the placing block 22 along the vertical rod 8, sleeving the packing film vertically downward on the outer side walls of the multiple cutting discs, and using the placing plate 21 to support the packing film, with the annular platform 11 rotating on the convex platform 1, the annular platform 11 drives the box body 2 to rotate around the central rod 12 through the internal gear 13. When the box body 2 drives the two U-shaped push rods 28 to pass between the T-shaped block 5 and the extrusion block 52, both the T-shaped block 5 and the extrusion block 52 extrude the two U-shaped push rods 28 through the arc-shaped surfaces, causing the two U-shaped push rods 28 to push the two moving blocks 23 to slide along the chute 71 towards both sides of the box body 2. The two moving blocks 23 drive the two pairs of clamping rods 27 to slide along the through slots until the two pairs of clamping rods 27 jointly clamp on the inner side walls of the multiple cutting discs through the rubber blocks 4. Under the self-elastic action of the second spring 26, the second spring 26 pushes the two clamping plates 24 to slide towards each other along the chute 71, causing the clamping plates 24 to engage with the moving blocks 23 through the teeth, thereby fixing the positions of the moving blocks 23 inside the box body 2. Continuing to rotate the annular platform 11 to make the box body 2 located on the side close to the hot air gun 14, the hot air gun 14 heats one side of the packing film on the cutting disc. Starting the motor 31, the motor 31 drives the external gear 32 to rotate through the output end, the external gear 32 drives the internal gear 13 to rotate through the teeth, and the internal gear 13 drives the placing plate 21 and the placing block 22 to rotate through the box body 2. Under the clamping action of the clamping rods 27, the positions of the cutting discs on the placing block 22 are fixed, and the placing plate 21 drives the multiple cutting discs to rotate synchronously through the placing block 22, so that all the packing films on the cutting discs pass through the air outlet of the hot air gun 14, improving the thermoplastic effect of the hot air gun 14 on the packing film and enhancing the packaging effect of the packing film on the cutting discs;

[0027] After the packaging is completed, by pulling the pull rods 29 on both sides of the box body 2, the pull rods 29 drive the two clamping plates 24 to slide towards both sides of the box body 2, separating the two clamping plates 24 from the two moving blocks 23 and releasing the limit on the moving blocks 23. Under the self-elastic action of the first spring 25, the first spring 25 pulls the two moving blocks 23 to slide towards each other along the chute 71, and the moving blocks 23 drive the two pairs of clamping rods 27 and the rubber blocks 4 to slide towards each other along the through slots, separating the rubber blocks 4 from the cutting discs and releasing the limit on the cutting discs, and then taking out the multiple packaged cutting discs upward along the vertical rod 8.

[0028] Embodiment 2

[0029] As Figure 3 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes that a fixed block 6 is fixedly connected to the outer side wall of the convex platform 1, an outer arc-shaped pulling block 61 is fixedly connected to the top of the fixed block 6, a convex block is fixedly connected to one side of the central rod 12 close to the outer arc-shaped pulling block 61, and an inner arc-shaped pulling block 62 is fixedly connected to the central rod 12 through the convex block.

[0030] In this embodiment, by providing the outer arc-shaped pulling block 61 and the inner arc-shaped pulling block 62, after the packaging is completed, the motor 31 is controlled to drive the internal gear 13 and the box body 2 to rotate by ninety degrees. The annular platform 11 continues to drive the box body 2 to rotate. When the box body 2 passes between the outer arc-shaped pulling block 61 and the inner arc-shaped pulling block 62, both the outer arc-shaped pulling block 61 and the inner arc-shaped pulling block 62 pull the two pull rods 29 with the arc-shaped surfaces, thereby releasing the limit on the cutting piece, and further reducing the labor intensity of the workers.

[0031] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
