Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, specifically a feeding device for rubber production. Background Technology

[0002] With the rapid development of modern industry, especially the chemical industry, there are many types of rubber products. They are generally made from solid rubber, i.e., raw rubber. The production process mainly includes raw material preparation, plasticizing, mixing, molding, vulcanization, finishing, and inspection. In the process of rubber production, the raw rubber needs to be transported to the processing equipment for heating and plasticizing. Therefore, a feeding device for rubber production is used to add some auxiliary materials to the processing equipment.

[0003] Traditional equipment relies on operators to manually cut open packaging bags with knives or other tools before dumping materials during the bag-breaking and feeding process. The dust generated during this process will directly escape into the workshop air, posing serious dust pollution and occupational health problems. This not only pollutes the working environment and endangers the respiratory health of operators, but also may lead to occupational diseases due to long-term inhalation of rubber dust. Furthermore, the escaped and suspended dust is easy to settle on the surface of the equipment and other areas, increasing the cleaning burden, which has certain shortcomings. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figure 1 - Figure 5This utility model provides a technical solution: a feeding device for rubber production, including a bag-breaking box 1, a purification box 3 fixedly installed at one end of the upper part of the bag-breaking box 1, a suction pipe 32 fixedly connected to one end of the purification box 3, a suction hood 33 fixedly connected to one end of the suction pipe 32, side plates 35 fixedly installed at both ends of the middle of the purification box 3, a filter screen 36 slidably engaged in the middle of the two sets of side plates 35, a connecting rod 37 fixedly connected to one end of the filter screen 36, a fixing plate 38 fixedly installed at the middle of the upper part of the bag-breaking box 1, a turntable 39 rotatably installed at the middle of one end of the fixing plate 38, an eccentric rod 42 fixedly installed on one side of the turntable 39, a rotating shaft 41 fixedly installed at the middle of the lower part of the fixing plate 38, a swing arm 43 rotatably installed on the surface of the rotating shaft 41, a guide groove 44 opened in the middle of the swing arm 43, and a swing arm 43 rotatably installed at one end of the swing arm 43. A bushing 45 is provided. A side support plate 46 is fixedly installed at the other end of the upper middle part of the bag breaking box 1. A suction hood 33 is fixedly installed on one side of the middle part of the bag breaking box 1. A baffle 34 is fixedly installed in the middle part of the suction hood 33. A cover plate 31 is fixedly installed at the upper end of the purification box 3 by screws. An exhaust fan 30 is provided at the other end of the purification box 3. The air inlet of the exhaust fan 30 is connected to the other end of the purification box 3. The size of the filter screen 36 is slightly wider than the distance between the two sets of side plates 35. A connecting rod 37 is slidably engaged in the middle part of the purification box 3. The other end of the connecting rod 37 is slidably engaged in the upper part of the middle part of the side support plate 46. An eccentric rod 42 is slidably engaged in the middle part of the suction hood 33. A bushing 45 is fixedly installed on the outside of the connecting rod 37. A motor 40 is fixedly installed in the middle part of the other end of the fixing plate 38. The output end of the motor 40 passes through the fixing plate 38 and is fixedly connected to the turntable 39.

[0023] In this embodiment, the dust generated during the bag-breaking process can be quickly drawn into the purification box 3 through the cooperation of the exhaust fan 30, the suction hood 33, and the suction pipe 32, preventing dust from spreading into the production environment, effectively improving the air quality in the workshop, protecting the health of operators, and meeting environmental protection requirements. The filter screen 36 inside the purification box 3 can filter the inhaled dust, intercepting particulate pollutants and reducing the impact of dust emissions on the external environment. The dust will be trapped and accumulated on one side of the filter screen 36, while clean air will pass through the filter screen 36 and be discharged from the exhaust port of the exhaust fan 30. The baffle 34 can prevent some rubber particles from being simultaneously drawn in, and the filter screen 36 can also achieve self-cleaning and re-filtration. During the process, the user can start the motor 40, which drives the turntable 39 and the eccentric rod 42 to rotate. Through the linkage of the swing arm 43, the guide groove 44, and the bushing 45, the connecting rod 37 can drive the filter screen 36 to slide back and forth between the side plates 35, automatically shaking off and cleaning the dust adhering to the filter screen 36. This eliminates the need for frequent manual disassembly and cleaning, greatly improving the continuous operation capability of the equipment. The size of the filter screen 36 is slightly larger than the distance between the two sets of side plates 35, which can prevent the filter screen 36 from falling off when it moves back and forth. The cover plate 31 of the purification box 3 is fixed with screws. Every once in a while, the user can unscrew the screws that fix the cover plate 31 to facilitate centralized cleaning of the dust accumulated in the purification box 3.

[0024] Example 2: Figure 1 - Figure 3 As shown, cylinders 20 are fixedly installed on both sides of the upper middle part of the bag breaking box 1. The output ends of the two cylinders 20 pass through the bag breaking box 1 and are fixedly installed with pressure plates 21. A door 12 is installed at one end of the bag breaking box 1 by a hinge. An observation window 13 is opened at the upper part of the middle of the door 12. A bag breaking disc 14 is fixedly installed at the lower part of the middle of the bag breaking box 1. A bag breaking blade 15 is fixedly installed at the upper part of the middle of the bag breaking disc 14. A baffle 16 is fixedly installed at the lower part of the middle of the bag breaking disc 14. A bracket 11 is fixedly installed at the lower end of the bag breaking box 1. A feeding hopper 17 is fixedly connected to the middle of the lower end of the bag breaking box 1. A guide pipe 18 is fixedly installed at the lower end of the feeding hopper 17. A spiral feeding rod 19 is rotatably installed at the middle of the guide pipe 18. The guide pipe 18 is located at one end of the feeding hopper 17 and is connected to the feeding hopper 17. The feeding hopper 17 is located at the middle of the bracket 11.

[0025] In this embodiment, the cylinder 20 drives the pressure plate 21 to press down, which, in conjunction with the bag-breaking blade 15 on the bag-breaking disc 14, can quickly slit the rubber raw material packaging bag, replacing manual bag breaking, greatly improving bag breaking efficiency and reducing manual labor intensity. After the bag is broken, the raw material falls into the feeding hopper 17 after passing through the baffle 16, and then is continuously and uniformly conveyed by the rotation of the spiral feeding rod 19 in the guide pipe 18, ensuring the stability of material supply for subsequent processes. The other end of the guide pipe 18 is connected to the subsequent rubber processing equipment, wherein the bag breaking... The baffle 16 below the disc 14 can effectively intercept packaging bag fragments, separating the rubber raw material from the packaging bag, ensuring the purity of the raw material and preventing impurities from affecting the quality of rubber products. The door 12 is installed by hinge rotation. After opening, it can be conveniently cleaned, maintained or replaced by components such as the bag breaking disc 14 and the bag breaking blade 15. It can also be closed during bag breaking to ensure the airtightness of the bag breaking box 1. The observation window 13 on the door 12 allows the operator to observe the bag breaking and material falling in the bag breaking box 1 in real time, which is convenient for timely detection and handling of abnormalities.

[0026] Working principle:

[0027] like Figure 1 - Figure 5 As shown, during operation, the operator places the packaging bag containing rubber raw materials into the bag-breaking box 1, closes the box door 12, and can observe the internal situation in real time through the observation window 13. Then, the cylinder 20 is activated, its output end pushing the pressure plate 21 downwards, which, in conjunction with the bag-breaking blade 15 on the bag-breaking disc 14, cuts the packaging bag. The broken rubber raw materials pass through the baffle 16 and fall into the feed hopper 17. The baffle 16 below the bag-breaking disc 14 effectively intercepts packaging bag fragments, separating the rubber raw materials from the packaging bags, ensuring the purity of the raw materials and preventing impurities from affecting the quality of rubber products. The raw materials entering the feed hopper 17 fall into the guide pipe 18, where the rotating screw feeder 19 continuously and evenly transports the rubber raw materials in the feed hopper 17 to subsequent rubber processing equipment.

[0028] During the bag-breaking process, the exhaust fan 30 is started simultaneously. Under the negative pressure of the exhaust fan 30, the dust generated during the bag-breaking process is sucked into the purification box 3 through the suction hood 33 and the suction pipe 32. During the process, some of the rubber on the baffle 34 can be sucked in. After the dust enters the purification box 3, it is intercepted by the filter screen 36. Clean air passes through the filter screen 36 and is discharged through the exhaust port of the exhaust fan 30, achieving efficient dust filtration. The filter screen can achieve self-cleaning. During the filtration process, the motor 40 is started simultaneously, and the motor 40 drives the turntable 39 to rotate. The eccentric rod 42 on the turntable 39 rotates accordingly. The eccentric rod 42 slides in the guide groove 44 of the swing arm 43, causing the swing arm 43 to swing around the rotating shaft 41. During the swinging process, the bushing 45 at one end of the swing arm 43 drives the connecting rod 37 to reciprocate, thereby causing the filter screen 36 to slide back and forth between the two sets of side plates 35. During this process, the dust accumulated on the filter screen 36 is automatically shaken off, achieving self-cleaning. The filter screen 36 is slightly larger than the distance between the two sets of side plates 35, which can prevent the filter screen 36 from falling off when it moves back and forth. Users can also periodically unscrew the screws of the cover plate 31 at the top of the purification box 3, open the cover plate 31, and clean the dust accumulated inside the purification box 3.
