Description

Technical Field

[0001] This utility model relates to the field of rubber band production, and in particular to a rubber band production feeding device. Background Technology

[0002] Currently, rubber bands have a wide range of applications, and different industries have different choices. Rubber bands can be divided into two types: ordinary practical type and safe and environmentally friendly type. Silicone rubber bands belong to the safe and environmentally friendly type. The price of rubber is cheap, and the market price is calculated by kilogram. Therefore, this type can be chosen for those with less demanding requirements. Silicone rubber bands are mainly produced by high temperature molding by silicone rubber band manufacturers. The material is more expensive, and the price is based on a fixed amount. However, the product quality and service life have great advantages.

[0003] Rubber bands are largely made of rubber, and the varying sizes of rubber pieces result in different processing times, affecting production efficiency. Furthermore, the inconsistent sizes of the rubber-filled cylinders can easily cause blockages at the discharge port, hindering the transfer of raw materials. Improvements are needed in these areas. Utility Model Content

[0006] As a further description of the above technical solution:

[0007] The top of the feeding cylinder is fixedly connected to a support frame, and the top of the third rotating shaft is rotatably connected to the middle of the support frame.

[0008] As a further description of the above technical solution:

[0010] As a further description of the above technical solution:

[0011] A first motor is fixedly connected to the middle of the bottom of the pulverizing tank, and the drive end of the first motor is fixedly connected to the bottom of the first rotating shaft.

[0012] As a further description of the above technical solution:

[0013] The bottom end of the feeding frame is uniformly and fixedly connected with multiple first support columns.

[0014] As a further description of the above technical solution:

[0016] As a further description of the above technical solution:

[0017] A discharge frame is fixedly connected to the left side of the crushing tank, and the left side of the discharge frame is fixedly connected to the right side of the conveying frame.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, a sieve plate is added. The rubber slides down the conveyor frame onto the sieve plate. Smaller rubber pieces will flow down from the opening at the bottom of the sieve plate, while larger pieces will move into the inside of the crushing tank, be crushed to a certain size, and then flow back into the conveyor frame from the discharge frame. This achieves rubber size screening and can crush the rubber evenly. Smaller rubber pieces can be processed faster, improving production efficiency.

[0020] 2. In this utility model, a third rotating shaft is added. The second motor is started to make the third rotating shaft start to rotate. The anti-blocking blocks around the third rotating shaft keep the distance between the rubber piles loose, avoiding blockage caused by rubber accumulation. This ensures the stability of the output to a certain extent and reduces the production time wasted due to blockage. Attached Figure Description

[0029] Reference Figure 1-4This utility model provides an embodiment of a rubber band production feeding device, including a feeding frame 1. A feeding cylinder 3 is fixedly connected to the rear top of the feeding frame 1 via a mounting bracket. A third rotating shaft 18 is provided inside the feeding cylinder 3. Multiple anti-blocking blocks 19 are evenly fixedly connected around the outer circumference of the third rotating shaft 18. A feeding frame 5 is fixedly connected to the upper right side of the feeding frame 1. A crushing tank 8 is fixedly connected to the right side of the feeding frame 5. A sieve plate 12 is fixedly connected to the middle of the feeding frame 1. The sieve plate 12 is inclined and fixedly connected inside the feeding frame 1. When the sieve plate 12 is added, rubber slides down the feeding frame 1 onto the sieve plate 12. Smaller pieces of rubber flow downwards from the opening at the bottom of the sieve plate 12, while larger pieces move into the crushing tank 8. A first rotating... A first rotating shaft 14 has a first gear 6 fixedly connected to its top end. Multiple second rotating shafts 17 are evenly connected around the inside of the crushing tank 8. Each second rotating shaft 17 has a second gear 7 fixedly connected to its top end. The first gear 6 meshes with the second gear 7. Multiple stirring blades 15 are evenly fixedly connected around the first rotating shaft 14. Multiple gathering plates 16 are fixedly connected around the outside of the second rotating shafts 17. The stirring blades 15 crush the rubber raw material. At the same time, the first gear 6 and the second gear 7 at the top of the first rotating shaft 14 mesh with each other, driving each second rotating shaft 17 to rotate. The gathering plates 16 on the outside of the second rotating shaft 17 push the rubber raw material falling on the outside of the inside of the crushing tank 8 towards the inside, so that it is fully crushed.

[0030] A support frame 4 is fixedly connected to the top of the feeding cylinder 3. The top of the third rotating shaft 18 is rotatably connected to the middle of the support frame 4. A second motor 13 is fixedly connected to the top of the middle of the support frame 4. The drive end of the second motor 13 is fixedly connected to the top of the third rotating shaft 18. A first motor 11 is fixedly connected to the middle of the bottom of the crushing tank 8. The drive end of the first motor 11 is fixedly connected to the bottom of the first rotating shaft 14. Multiple first support columns 2 are evenly fixedly connected to the bottom of the conveying frame 1. Multiple second support columns 10 are evenly fixedly connected to the bottom circumference of the crushing tank 8. A discharge frame 9 is fixedly connected to the left side of the crushing tank 8. The left side of the discharge frame 9 is fixedly connected to the right side of the conveying frame 1. The discharge port of the crushing tank 8 is relatively small. When the rubber raw material is crushed to the size of the discharge port, it flows back into the conveying frame 1 from the discharge port. The feeding is completed as the raw material is evenly transported outward.

[0031] Working principle: Start the second motor 13 to make the third rotating shaft 18 start to rotate. Add raw materials and let them flow into the conveying frame 1 through the feeding cylinder 3. The raw materials are transferred downward inside the conveying frame 1. Smaller rubber materials will flow out through the opening at the bottom of the screen plate 12, while larger ones will flow into the feeding frame 5 through the inclined screen plate 12, thus entering the crushing tank 8. Start the first motor 11 to make the first rotating shaft 14 rotate. The rubber materials are crushed by the stirring blades 15. At the same time, the first gear 6 and the second gear 7 at the top of the first rotating shaft 14 mesh and drive each of the second rotating shafts 17 to rotate. The gathering wide plate 16 outside the second rotating shaft 17 pushes the rubber materials that fall on the outside of the crushing tank 8 to move inward and crush them thoroughly. The discharge port of the crushing tank 8 is small. When the rubber materials are crushed to the size of the discharge port, they flow back into the conveying frame 1 from the discharge port. The feeding is completed as the materials are uniformly transported outward.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
