Description

Technical Field

[0001] This application relates to the field of crushers, and more particularly to a feeding device for a crusher. Background Technology

[0002] As a core piece of equipment for crushing and processing solid raw materials, pulverizers are widely used in chemical, plastics, and food processing industries. They use mechanical action to crush large raw materials into particle sizes that meet the requirements of subsequent processes. For example, in the processing of color masterbatch, larger color masterbatch particles need to be crushed into smaller, more uniform particles by a pulverizer to meet the needs of injection molding or mixing processes.

[0003] Chinese Patent CN222858510U discloses a pulverizer for color masterbatch raw materials, relating to the field of color masterbatch manufacturing technology. The pulverizer includes a support frame, a pulverizing box, a feed hopper, a discharge pipe, an electronic valve, connecting shafts, gears, and pulverizing rollers. The pulverizing box is mounted on the support frame. A feed hopper is fixedly connected to the top of the pulverizing box, and a discharge pipe is connected and communicates with the bottom of the pulverizing box. An electronic valve is installed on the discharge pipe. Two connecting shafts are rotatably arranged inside the pulverizing box, and pulverizing rollers are sleeved on the connecting shafts. Both connecting shafts extend to the outside of the pulverizing box, and gears are fixedly connected to both connecting shafts, with the two gears meshing with each other.

[0004] When using the aforementioned technologies, operators need to frequently manually move raw materials to higher places for feeding, which increases labor intensity and leads to higher labor costs. Utility Model Content

[0005] To reduce labor costs, this application provides a feeding device for a crusher.

[0006] The feeding device for a pulverizer provided in this application adopts the following technical solution: A feeding device for a crusher includes a frame, a moving component, and a storage bin. The moving component is used to move the storage bin and drive it closer to or further away from the crusher's feed hopper.

[0007] By adopting the above technical solution, the moving component is used to move the storage box closer to or away from the crusher feed hopper, making feeding more convenient and reducing manpower consumption.

[0008] Optionally, the frame has a movable slot, the top of which is located near the feed hopper of the crusher. The movable component includes a lead screw, a first motor, and a slider. The length direction of the lead screw is consistent with the length direction of the movable slot, and the lead screw is rotatably connected to the movable slot. The first motor is connected to the frame, and the output shaft of the first motor is connected to one end of the lead screw. The slider is threaded onto the lead screw and slides against the inner wall of the movable slot. The storage box is connected to the slider.

[0009] By adopting the above technical solution, the first motor drives the lead screw to rotate, which in turn causes the slider to move along the moving groove. The slider then drives the storage box to move, making the storage box closer to or further away from the crusher feed hopper, thus making the raw material feeding more convenient.

[0010] Optionally, the storage box is rotatably connected to the slider, the slider is connected to a rotating component, the rotating component is used to drive the storage box to rotate, and the storage box is connected to a guide assembly, the guide assembly is used to guide the raw material into the feed hopper of the crusher.

[0011] By adopting the above technical solution, when the moving component moves the storage box close to the feed hopper of the crusher during feeding, the rotating component drives the storage box to rotate, which makes it easier to adjust the angle of the storage box so that the raw material can be poured into the crusher. In addition, a guide component is added. When the storage box feeds into the crusher body, the guide component guides the raw material into the feed hopper of the crusher, improving the accuracy and efficiency of feeding.

[0012] Optionally, the storage bin has an opening at the top, and the guide assembly includes a guide plate and a moving part. The moving part is used to drive the guide plate to rotate and drive one end of the guide plate to be close to or away from the feed hopper of the crusher.

[0013] By adopting the above technical solution, when the storage bin feeds material into the crusher, the moving part drives the guide plate to move and drives one end of the guide plate to approach the crusher feed hopper, so that the raw material enters the crusher feed hopper along the guide plate, thereby making the raw material enter the crusher feed hopper more accurately.

[0014] Optionally, the moving component includes a first cylinder and a connecting rod. The first cylinder is connected to the storage bin, the guide plate is hinged to the piston rod of the first cylinder, one end of the connecting rod is hinged to the guide plate, and the other end of the connecting rod is hinged to the storage bin.

[0015] By adopting the above technical solution, when the storage bin feeds material into the crusher, the first cylinder drives the guide plate to move. The movement of the guide plate drives the connecting rod to rotate, causing the guide plate to rotate and drive one end of the guide plate to approach the crusher's feed hopper. When one end of the guide plate approaches the crusher's feed hopper, the rotating component drives the storage bin to rotate, pouring the raw material in the storage bin into the crusher's feed hopper. Some of the raw material falls onto the guide plate and moves along the guide plate into the crusher's feed hopper. In addition, the guide plate is added so that it covers the gap between the storage bin and the crusher, thereby reducing the situation where raw material falls into the gap between the storage bin and the crusher.

[0016] Optionally, both ends of the guide plate are connected to a first plate, and the two first plates are spaced apart to provide a moving channel for the raw materials to pass through.

[0017] By adopting the above technical solution and adding a first plate, the raw materials on the guide plate are reduced from falling off the sides of the guide plate during feeding, thus reducing material waste.

[0018] Optionally, a baffle is connected to the top of the storage bin, the baffle being located at the end of the storage bin near the crusher, and the baffle being located on the top of the guide plate.

[0019] By adopting the above technical solution and adding baffles, the amount of raw material falling into the gap between the guide plate and the storage box during feeding is reduced, thus reducing the waste of raw materials.

[0020] Optionally, a partition is connected to the inner wall of the storage bin, with one end of the partition connected to the bottom inner wall of the storage bin and the other end of the partition connected to the inner wall of the storage bin near the crusher.

[0021] By adopting the above technical solution and adding a baffle, the raw material can be further guided to the feed hopper of the crusher, reducing the accumulation of raw material in the storage bin during feeding. Optionally, a dust cover is also included, which is installed over the feed hopper of the crusher and has a connection port for the raw materials to enter.

[0022] By adopting the above technical solution and adding a dust cover, the amount of smoke and dust generated during the raw material feeding process can be reduced, thus achieving the effect of dust prevention.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. Utilizing a movable component to move the storage bin closer to or further away from the crusher's feed hopper makes feeding more convenient and reduces manpower consumption; 2. The first motor drives the lead screw to rotate, which in turn causes the slider to move along the moving groove. The slider drives the storage box to move, so that the storage box is closer to or farther away from the feed hopper of the crusher, making the feeding of raw materials more convenient. 3. When the storage bin feeds into the crusher, the first cylinder drives the guide plate to move. The movement of the guide plate drives the connecting rod to rotate, causing the guide plate to rotate and drive one end of the guide plate to approach the crusher's feed hopper. When one end of the guide plate approaches the crusher's feed hopper, the rotating part drives the storage bin to rotate, pouring the raw material in the storage bin into the crusher's feed hopper. Some of the raw material falls onto the guide plate and moves along the guide plate into the crusher's feed hopper. The addition of a guide plate covers the gap between the storage bin and the crusher, thereby reducing the amount of raw material falling into the gap between the storage bin and the crusher.

[0039] The principle of the feeding device for a crusher according to an embodiment of this application is as follows: During use, raw materials are placed in the storage bin 300. The first motor 220 drives the lead screw 210 to rotate, thereby causing the slider 230 to move vertically upwards. The storage bin 300 follows the slider 230, moving vertically upwards until it approaches the feed hopper. When the storage bin 300 approaches the feed hopper, the first cylinder 421 drives the moving block 413 to move along the height of the storage bin 300. The moving block 413 drives the connecting block 412 and the guide plate 410 to move. The guide plate 410 moves and drives the connecting rod 422 to rotate, causing the guide plate 410 to rotate and drive the top of the guide plate 410 away from the storage box 300. When the top of the guide plate 410 is tilted away from the storage box 300, the second motor 231 drives the storage box 300 to rotate, causing the storage box 300 to tilt. The raw materials in the storage box 300 are poured into the feeding hopper, and some raw materials fall onto the guide plate 410 and enter the feeding hopper along the guide plate 410, thus completing the feeding of raw materials. This makes the feeding of raw materials more convenient and reduces the labor cost consumed in feeding raw materials.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
