Description

Technical Field

[0001] The utility model relates to the technical field of polypropylene particle production, in particular to a cutting device for polypropylene particle production. Background Art

[0002] At present, polypropylene is a thermoplastic resin made by polymerization of propylene. It is a white waxy material with a transparent and light appearance. Polypropylene is divided into three types according to the arrangement of methyl groups: isotactic polypropylene, atactic polypropylene and syndiotactic polypropylene. It is widely used in the production of fiber products, medical equipment, automobiles, chemical containers and other products, and is also used in the packaging of food and medicine.

[0003] There are many existing technologies for cutting devices for polypropylene particle production, such as:

[0026] Most polypropylene particle production and cutting devices can perform sealed cutting on polypropylene particles, but it is difficult to feed polypropylene particles. If the polypropylene particles are directly poured into the interior of the cutting chamber, it will not only affect the efficiency of the polypropylene particle cutting, but also reduce the quality of the polypropylene particle cutting, resulting in a waste of time. If the polypropylene particles are poured from the feed port at a low flow rate, it is inevitable that polypropylene particles will splash from the feed port when cutting, resulting in a waste of polypropylene particles, thereby reducing the practicality of the polypropylene particle cutting device.

[0027] See also Figure 1-Figure 5 The embodiment of the utility model shown in the figure comprises a base 10, a pushing assembly 11 is arranged inside the upper surface of the base 10, a bottom plate 12 is arranged on the upper surface of the pushing assembly 11, material receiving boxes 13 are arranged on both sides of the upper surface of the bottom plate 12, an auxiliary assembly 14 for receiving the two material receiving boxes 13 is arranged in the middle of the upper surface of the bottom plate 12, and the pushing assembly 11 is used to assist the two material receiving boxes 13 in exchanging; two supporting columns 20 are arranged on both sides of the upper surface of the base 10, a shell 21 is arranged on the upper surface of the supporting columns 20, a loading box 22 is arranged at the opening of the upper surface of the shell 21, sealing assemblies 23 are arranged on both sides of the loading box 22 extending to the inside of the shell 21, and the sealing assembly 23 is used to control the discharge of polypropylene particles, a cutting machine 24 for cutting polypropylene particles is arranged inside the shell 21, and a discharge hopper 25 is arranged at the opening below the shell 21.

[0028] First, the specific structure of the pushing component 11 is disclosed. The pushing component 11 at least includes a moving groove 111. The upper surface of the base 10 is provided with the moving groove 111. A multi-stage cylinder 112 is arranged inside the moving groove 111. The piston rod of the multi-stage cylinder 112 is provided with a slide plate 113. The upper surface of the slide plate 113 is fixedly connected to the lower surface of the base plate 12.

[0029] The improvement lies in that: the multi-stage cylinder 112 is connected to a power source to make it work, and the material receiving box 13 close to the multi-stage cylinder 112 can be moved to the bottom of the lower hopper 25 through the pushing work of the piston rod of the multi-stage cylinder 112. At this time, the material receiving box 13 on the side away from the multi-stage cylinder 112 can be replaced. Similarly, when the piston rod of the multi-stage cylinder 112 is reset, the material receiving box 13 on the side away from the multi-stage cylinder 112 can be moved to directly under the lower hopper 25. Not only is the operation convenient, but the cutting machine 24 can also work during the material unloading process, which not only improves the work efficiency of the polypropylene particle production, but also improves the flexibility of the use of the cutting device, thereby increasing the economic benefits.

[0030] Secondly, the specific structure of the auxiliary component 14 is disclosed. The auxiliary component 14 at least includes a support plate 141. The support plate 141 is arranged in the middle of the upper surface of the bottom plate 12. The upper surface of the support plate 141 is arranged with a receiving plate 142. Side plates 143 are arranged on both sides of the receiving plate 142.

[0031] The improvement lies in that the receiving plate 142 is supported by the support plate 141 so that the receiving plate 142 is higher than the height of the material receiving box 13, and the two material receiving boxes 13 are connected by the receiving plate 142 to prevent the polypropylene particles from flowing out of the material receiving box 13 when unloading, thereby improving the unloading work of the cutting device, reducing the time consumption, and thus improving the practicability of the cutting device.

[0032] The specific structure of the sealing component 23 is disclosed again. The sealing component 23 at least includes a mounting shell 231. The mounting shells 231 are arranged at the oblique edges on both sides of the loading box 22. A mounting plate 232 is arranged inside the mounting shell 231. A motor 233 is arranged on the upper surface of the mounting plate 232. The output shaft of the motor 233 extends to the lower surface of the mounting plate 232 and is coaxially connected with a main tooth 234. The main tooth 234 is meshingly connected with a rack 235. A sealing plate 236 is arranged at one end of the rack 235, and the sealing plate 236 is inserted into the inside of the side opening of the loading box 22.

[0033] The improvement lies in that: the motor 233 is connected to a power source to make it work, and the output shaft of the motor 233 rotates clockwise to drive the main gear 234 to rotate, and drives the rack 235 to approach the upper material box 22 through the meshing connection, and the opening below the loading box 22 is sealed by the sealing plate 236. At this time, the polypropylene particles can be poured into the loading box 22, and then the cover plate is covered, and the output shaft of the motor 233 rotates counterclockwise to make the rack 235 away from the loading box 22, and the sealing plate 236 can be opened to unload the polypropylene particles and make the polypropylene particles flow to the cutting machine 24. Not only is the operation simple, but the size of the loading can be controlled during the loading process, which improves the flexibility of the cutting device, and also avoids the polypropylene particles from splashing out of the loading box 22 during the cutting process, preventing the polypropylene particles from being wasted, and also improving the safety of the polypropylene particle cutting, thereby avoiding economic losses.

[0034] In order to connect the two material receiving boxes 13 and prevent the polypropylene particles from flowing out when the material receiving boxes 13 are replaced, thereby causing waste of polypropylene particles and reducing the practicality of the cutting device, the receiving plate 142 is in an inverted "V" shape.

[0035] The improvement lies in that: by forming the receiving plate 142 into an inverted "V" shape, the polypropylene particles can be discharged along the slope of the receiving plate 142, thereby improving the working efficiency of the polypropylene particles. When replacing the receiving box 13, it also prevents the polypropylene particles from flowing between the two receiving boxes 13, preventing the waste of polypropylene particles, and reducing the frequency of failures of polypropylene particles during the cutting production process, thereby improving the practicability of the cutting device.

[0036] In summary, the working principle of this scheme is as follows: first, insert the two material receiving boxes 13 into the upper surface of the bottom plate 12, connect the motor 233 to the power supply to make it work, and rotate the output shaft of the motor 233 clockwise to drive the main gear 234 to rotate, and drive the rack 235 to approach the upper material box 22 through the meshing connection, and seal the opening below the upper material box 22 through the sealing plate 236. At this time, the polypropylene particles can be poured into the upper material box 22, and then the cover plate is covered, and the output shaft of the motor 233 is rotated counterclockwise to make the rack 235 away from the upper material box 22, and the sealing plate 236 can be opened to unload the polypropylene particles. At the same time, the cutting machine 24 is powered on to make it work, so that the polypropylene particles are cut, and then flow from the lower hopper 25 to the inside of the material receiving box 13. Then, when the material receiving box 13 on the side away from the multi-stage cylinder 112 is loaded, the multi-stage cylinder 112 is powered on to make it work. Through the pushing work of the piston rod of the multi-stage cylinder 112, the material receiving box 13 close to the multi-stage cylinder 112 can be moved to the bottom of the lower hopper 25. At this time, the material receiving box 13 on the side away from the multi-stage cylinder 112 can be replaced. Similarly, when the piston rod of the multi-stage cylinder 112 is reset, the material receiving box 13 on the side away from the multi-stage cylinder 112 can be moved to the bottom of the lower hopper 25, so that the work of cutting the polypropylene particles can be completed.
