Abstract
Description
Technical Field
[0001] This utility model relates to the field of crusher feeding technology, and in particular to a feeding device for a polymer material crusher. Background Technology
[0002] In the production and processing of polymer materials, they are crushed using a pulverizer. Polymer materials are typically fed into the pulverizer through the feed hopper at the top. However, when the pulverizer is relatively high, the polymer materials need to be manually moved and fed into the feed inlet. For example, Chinese patent application CN202121456289.X discloses a pulverizer feeding device and pulverizer, which involves manually placing a bag containing materials onto a flap. A cylinder drives the flap to flip up, achieving the feeding state. The flap is designed with segmented angles; after flipping up, the angle between the front end and the horizontal increases, while the angle at the rear end is gentler. This design reduces the space occupied by the feeding device before flipping up and allows the materials in the bag to automatically slide down the flap into the pulverizer hopper under gravity after flipping up. However, it presents the following technical problems:
[0003] Although the above structure does not require manual handling, the flap needs to be flipped when feeding polymer materials into the crusher. The higher the position of the crusher's feed inlet, the longer the flap needs to be. It can be seen that the above structure has certain requirements for the placement space of the feeding device. When the feeding area is insufficient for the feeding device to flip, the above structure will not be usable. Therefore, the applicable scope of the above structure is relatively small.

Detailed Implementation
[0030] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.
[0031] Please see Figures 1-7 This utility model provides a feeding device for a polymer material crusher, including a feeding device 002.
[0032] The lower end of the feeding device 002 is equipped with a support device 001 for limiting the feeding device 002. The support device 001 includes a support base 100. A vertical plate 110 is fixedly installed on the upper end of the support base 100. A reciprocating screw 120 for controlling the feeding device 002 to move up and down is installed on the left side of the support base 100. A motor 121 for controlling the rotation of the reciprocating screw 120 is installed at the lower end of the reciprocating screw 120. The motor 121 is installed inside the support base 100 for easy maintenance.
[0033] The feeding device 002 includes a feeding assembly 300 for facilitating the feeding of polymer materials. The feeding assembly 300 includes a feeding box 310 for placing polymer materials. The polymer materials can be directly placed in the feeding box 310. By rotating the feeding box 310, the polymer materials are fed into the inside of the crusher.
[0034] Multiple anti-slip strips 311 are fixedly installed on the bottom wall of the inner cavity of the feeding box 310. When the packaging bag containing polymer material is large or heavy and it is inconvenient to manually pour the polymer material into the feeding box 310, the packaging bag containing polymer material can be directly placed into the feeding box 310, and the head of the packaging bag is opened to facilitate the flow out of the polymer material.
[0035] The lower end of the feeding assembly 300 is equipped with a lifting assembly 200, which is used to control the lifting of the feeding assembly 300 in conjunction with the reciprocating screw 120. The lifting assembly 200 includes a cylinder 230 for controlling the angle change of the feeding assembly 300.
[0036] A limiting cylinder 312 is fixedly installed on the right outer wall of the feeding box 310. A mounting seat 313 for limiting the cylinder 230 is fixedly installed on the lower left side of the feeding box 310. The telescopic end of the cylinder 230 is movably mounted on the mounting seat 313. A baffle 320 for limiting the polymer material is installed on the right side of the feeding box 310. The baffle 320 moves up and down on the right side of the feeding box 310 to block the polymer material. Electric push rods 321 for controlling the up and down movement of the baffle 320 are installed at the front and rear ends of the baffle 320. Base plates for supporting and limiting the electric push rods 321 are installed at the front and rear ends of the feeding box 310 so that the electric push rods 321 can control the up and down movement of the baffle 320.
[0037] Two clamping components 330 for limiting the positioning of polymer material packaging bags are installed inside the left side of the feeding box 310. A reciprocating screw 340 for controlling the reverse movement of the two clamping components 330 is installed in the middle of the clamping components 330. The spiral grooves at the front and rear ends of the reciprocating screw 340 rotate in opposite directions. A handwheel 341 is fixedly installed at the front end of the reciprocating screw 340. When the polymer material packaging bag is put into the feeding box 310, the distance between the two clamping components 330 is adjusted by rotating the handwheel 341, so as to limit the positioning of packaging bags of different widths.
[0038] The clamping assembly 330 includes a lead screw nut 331. A fixed platform 332 is fixedly installed on the lower right side of the lead screw nut 331. A slot 333 is provided on the upper end of the fixed platform 332. A movable platform 334 is movably installed on the upper right side of the lead screw nut 331. A slider that slides within the lead screw nut 331 is installed on the left side of the movable platform 334, allowing the movable platform 334 to move only up and down. A locking block 335 that engages with the slot 333 is fixedly installed on the lower end of the movable platform 334. One end of the polymer material packaging bag is placed between the fixed platform 332 and the movable platform 334. The fixed platform 332 and the movable platform 334 engage with each other, and the locking block 335, in conjunction with the slot 333, clamps one end of the polymer material packaging bag. When the feeding box 310 is flipped, the polymer material falls into the feed port of the crusher, while the packaging bag remains inside the feeding box 310.
[0039] A vertical rod 336 is fixedly installed on the upper end of the moving platform 334. A handle 337 is fixedly installed on the top of the vertical rod 336. A spring 338 for controlling the downward movement of the moving platform 334 is sleeved on the outside of the vertical rod 336. A baffle for limiting the spring 338 is fixedly installed on the top side of the lead screw nut 331. When clamping the polymer material packaging bag, by pulling the handle 337, the moving platform 334 is moved away from the fixed platform 332, and the moving platform 334 squeezes the spring 338. The polymer material packaging bag is between the moving platform 334 and the fixed platform 332. When the handle 337 is released, the spring 338 pushes the moving platform 334 downward, so that the moving platform 334 and the fixed platform 332 are locked together, thereby clamping the polymer material.
[0040] The lifting assembly 200 includes a lifting platform 210. A screw nut 211 is fixedly installed on the middle left side of the lifting platform 210 to control its vertical movement in conjunction with a reciprocating screw 120. A support plate 220 is installed on the right side of the lifting platform 210 to support the loading box 310. One end of a cylinder 230 is movably installed at the lower end of the support plate 220. The reciprocating screw 120 is rotated by a motor 121, and guided by the screw nut 211, the lifting platform 210 synchronously drives the support plate 220 to move vertically, thereby driving the loading box 310 to move vertically.
[0041] A limiting seat 222 is fixedly installed on the upper right side of the support plate 220. A limiting shaft 223 is installed in the middle of the limiting seat 222, and one end of the limiting shaft 223 is inserted into the middle of the limiting cylinder 312, so that the feeding box 310 can rotate around the limiting shaft 223. A through groove 224 is provided in the middle of the support plate 220 to facilitate the extension and retraction of the cylinder 230.
[0042] By setting up the clamping component 330 and the baffle 320, the feeding box 310 can not only directly feed polymer materials into the feed inlet of the crusher, but also limit the packaging bag containing polymer materials, so that the polymer materials are fed into the feed inlet of the crusher while the packaging bag remains inside the feeding box 310.
[0043] When polymer materials are fed into the feed inlet of the crusher, the reciprocating screw 120, in conjunction with the screw nut 211, drives the lifting assembly 200 and the feeding assembly 300 to move upward. Then, the telescopic end of the cylinder 230 pushes the left side of the feeding box 310, causing the left side of the feeding box 310 to rise. The feeding box 310 rotates around the limit shaft 223, causing the polymer materials in the feeding box 310 to be fed into the crusher.
[0044] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
