Description

Technical Field

[0001] This utility model relates to the field of plastic granule processing technology, specifically to a mixing device for plastic granule processing. Background Technology

[0002] Plastic pellets, a common name for plastic granules, are raw materials used for storing, transporting, and processing plastics in a semi-finished form. Plastics are a type of polymer material, made from petroleum as a raw material, which can produce ethylene, propylene, vinyl chloride, styrene, etc. The molecules of these substances can react with each other under certain conditions to form compounds with very high molecular weights, i.e., polymers. In the processing of plastic pellets, different pellets need to be mixed and stirred evenly.

[0003] According to patent publication number CN 216682824 U, a mixing device for processing plastic granules is disclosed. During the mixing process, dust on the plastic granules flies out from the gaps around the dust removal frame. Dust on plastic granules at any position can fly out, and then the dust in the tank is sucked out through multiple dust suction ports, thereby improving the dust suction effect. However, when mixing plastic granules, this device cannot separate clumps of plastic granules, thus affecting the subsequent mixing efficiency.

[0004] To address this issue, we propose a mixing device for plastic pellet processing. Utility Model Content

[0026] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figure 1-5 As shown, this utility model provides a technical solution: a mixing device for processing plastic granules, including a support platform 1, a mixing tank 2 installed through the support platform 1, a cover 4 fixedly installed on the upper part of the mixing tank 2, a first discharge pipe 5 connected to the bottom of the mixing tank 2, and a connecting assembly 3 installed on the upper part of the support platform 1. The connecting assembly 3 includes a stirring mechanism 31 installed on the upper part of the mixing tank 2. A dust removal mechanism 32 is installed on the upper part of the support platform 1. A first valve is installed at the bottom end of the first discharge pipe 5. The stirring mechanism 31 includes a dust removal screen cylinder 311 fixedly installed on the lower part of the cover 4. A second discharge pipe is connected to the bottom of the dust removal screen cylinder 311, and a second valve is installed at the bottom end of the second discharge pipe. A conveying device is fixedly installed on the bottom of the inner wall of the dust removal screen cylinder 311 by a mounting column. A motor 313 is fixedly installed on the upper part of the cylinder 312 and the box cover 4 via a base. The output end of the motor 313 is fixedly connected to a first rotating shaft 314. The outer wall of the first rotating shaft 314 is fixedly connected to a first conical tooth 315, a transmission tooth 316, and a crushing roller 317. A crushing box 318 is fixedly installed on the upper part of the box cover 4. A feed hopper is connected to the upper part of the crushing box 318. A second rotating shaft 319 is rotatably connected to the inside of the box cover 4 via a bearing. A second conical tooth 3110 is fixedly connected to the top of the second rotating shaft 319. A connecting rod 3111 is fixedly connected to the outer wall of the second rotating shaft 319. A main stirring rod 3112 is fixedly connected to the outer end of the connecting rod 3111. A secondary stirring rod is fixedly connected to the outer wall of the main stirring rod 3112. A conveying blade 3113 is fixedly connected to the outer wall of the second rotating shaft 319.

[0029] In this embodiment, the first conical tooth 315 and the second conical tooth 3110 are meshed together. The first rotating shaft 314 is rotatably connected to the crushing box 318 through a bearing. The bottom of the crushing box 318 is connected to the box cover 4. Through the cooperation of the dust removal screen cylinder 311, the conveying cylinder 312, the motor 313, the first rotating shaft 314, the first conical tooth 315, the transmission tooth 316, the crushing roller 317, the crushing box 318, the second rotating shaft 319, the second conical tooth 3110, the connecting rod 3111, the main stirring rod 3112, and the conveying blade 3113, the plastic particles added to the mixing tank 2 can be crushed. This can prevent the plastic particles from clumping due to moisture or other reasons, which would affect the subsequent mixing operation. It can also convey the material at the bottom of the mixing tank 2 upwards, thereby preventing the material from accumulating at the bottom and affecting the mixing effect, and preventing the material from blocking during discharge.

[0030] Furthermore, there are two transmission teeth 316, two first rotating shafts 314, and two crushing rollers 317, and the two transmission teeth 316 are meshed together.

[0031] In operation, the device first manually feeds plastic granules into the crushing chamber 318 from the feed hopper. Then, the motor 313 drives the first rotating shaft 314 to rotate. Under the meshing action of two transmission teeth 316, the crushing rollers 317, fixedly connected to the outer wall of the first rotating shaft 314, rotate in opposite directions, thus crushing and separating the plastic granules. This prevents the plastic granules from clumping due to moisture or other reasons, which would affect subsequent mixing operations. After crushing and separating, the plastic granules fall downwards into the dust collection cylinder 311. Furthermore, when the first rotating shaft 314 rotates, the action of the first conical teeth 315 and the second conical teeth 3110 allows... The second rotating shaft 319 rotates synchronously, which causes the connecting rod 3111, fixedly connected to the outer wall of the second rotating shaft 319, to drive the main stirring rod 3112 to rotate synchronously. Under the action of the auxiliary stirring rod, the material in the dust removal screen cylinder 311 can be stirred and mixed. When the second rotating shaft 319 rotates, the conveying blades 3113, fixedly connected to the outer wall of the second rotating shaft 319, can rotate synchronously. With the cooperation of the conveying cylinder 312, the material at the bottom of the dust removal screen cylinder 311 can be conveyed upward, thereby preventing the material from accumulating at the bottom and affecting the mixing effect. It can also prevent the material from clogging when discharging, increasing the applicability of the device.

[0033] Based on Example 1, a preferred embodiment of the mixing device for plastic pellet processing provided by this utility model is, for example... Figures 1 to 5As shown: The dust removal mechanism 32 includes a collection box 321 fixedly installed on the upper part of the support platform 1. A fan 322 is fixedly installed on the upper part of the collection box 321. A connecting pipe 326 is connected to one side of the collection box 321. An installation groove 323 is opened inside the collection box 321. An installation frame 324 is inserted into the installation groove 323. A dust removal plate 325 is fixedly installed inside the installation frame 324. A sliding groove 327 is opened on the outer side of the collection box 321. A sliding rod 328 is fixedly connected to the inner wall of the sliding groove 327. A slider 329 is slidably connected to the outer wall of the sliding rod 328. A spring 3210 is fixedly connected to the inner wall of the sliding groove 327. A limit rod 3211 is fixedly connected to the outer side of the slider 329. A door is sealed on the left side of the collection box 321. A sealing ring is fixedly connected to the inner wall of the collection box 321, and the sealing ring is located in the gap between the installation groove 323 and the installation frame 324.

[0034] In this embodiment, the connecting pipe 326 is connected to the mixing tank 2, and the input end of the blower 322 is connected to the top of the collection box 321 through the absorption pipe. Through the cooperation of the collection box 321, blower 322, mounting groove 323, mounting frame 324, dust removal plate 325, connecting pipe 326, slide 327, slide rod 328, slider 329, spring 3210, and limit rod 3211, dust and impurities generated during the plastic mixing process can be absorbed and filtered, thereby improving the quality of the finished plastic product and preventing dust from being directly discharged into the external environment. At the same time, it is convenient for manual disassembly of the mounting frame 324, which facilitates manual cleaning of the dust removal plate 325, thus facilitating subsequent use.

[0035] Furthermore, one end of the spring 3210 is fixedly connected to the slider 329, and the inner side of the limiting rod 3211 is fitted against the outer side of the mounting frame 324.

[0036] When plastic granules are mixed and processed, the air in the collection box 321 can be drawn out by the blower 322. Then, under the action of the connecting pipe 326, dust and impurities in the mixing tank 2 can be drawn into the collection box 321. Subsequently, under the action of the dust removal plate 325, the dust and impurities can be blocked in the collection box 321, thereby improving the quality of the finished plastic product and preventing dust from being directly discharged into the external environment. Furthermore, when it is necessary to disassemble the mounting frame 324, simply push the limiting rod 3211 manually. Then, under the limiting action of the sliding rod 328 and the slider 329, the limiting rod 3211, which is fixedly connected to the outside of the slider 329, can be moved away from the outside of the mounting frame 324. Then, the mounting frame 324 can be pulled out manually to clean the dust removal plate 325, preventing the filter holes of the dust removal plate 325 from becoming clogged and affecting subsequent use.
