Description

Technical Field

[0001] This utility model relates to the field of material crushing and processing technology, and in particular to an auxiliary feeding device for a crusher. Background Technology

[0002] When separating the entire glass during the recycling of scrapped photovoltaic modules, a hot knife is needed to remove the backsheet. The removed backsheet usually needs to be crushed for subsequent resource recycling.

[0003] Currently, crusher feeding methods primarily rely on belt conveyors or vibrating feeders to directly feed material into the crusher's inlet. However, due to the hot-blade scraping process used in whole-glass separation, the backplate tends to curl up after scraping. This curled shape makes it difficult for the backplate to pass smoothly through the narrow-gap pressure rollers at the crusher's inlet. This causes the curled backplate to frequently clog the inlet during feeding, requiring frequent manual intervention and cleaning, severely impacting production efficiency. Even with some devices employing simple guiding or extrusion structures, stable and efficient feeding cannot be achieved because the curling and unwinding problems of the backplate cannot be effectively resolved.

[0004] Therefore, an auxiliary feeding device for a crusher is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary feeding device for a crusher, which aims to solve or improve at least one of the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following solution: This utility model provides an auxiliary feeding device for a crusher, comprising:

[0007] A downward pressing conveyor belt assembly is used to be installed at the feed inlet of a crusher. A feed conveyor belt assembly is installed at the feed inlet of the crusher. The downward pressing conveyor belt assembly is located above the feed conveyor belt assembly. The downward pressing belt in the downward pressing conveyor belt assembly rotates in the opposite direction to the feed belt in the feed conveyor belt assembly. The rotational speed of the feed belt in the feed conveyor belt assembly is greater than the rotational speed of the downward pressing belt in the downward pressing conveyor belt assembly.

[0008] A lifting support is installed on the crusher. The lifting end of the lifting support is connected to the downward conveyor belt assembly. The lifting support is used to adjust the distance between the downward conveyor belt assembly and the feed conveyor belt assembly.

[0009] Preferably, the feed end of the crusher is fixedly connected to a bottom support frame, the feed conveyor belt assembly includes two first rollers rotatably connected to the bottom support frame, the feed belt is conveyed on the two first rollers, a first motor is fixedly connected to the bottom support frame, and the output shaft of the first motor is fixedly connected to either of the first rollers.

[0010] Preferably, the lifting bracket includes a mounting frame, the downward conveyor belt assembly is disposed on the mounting frame, two connecting rods are rotatably connected to both sides of the mounting frame, and the end of the connecting rod away from the mounting frame is rotatably connected to the bottom support frame; a driving assembly is disposed on the support frame, and the driving assembly is connected to the mounting frame.

[0011] Preferably, the drive assembly includes two struts fixed to the bottom support frame, a bracket rotatably connected between the two struts, the bracket being located above the mounting frame, a third motor fixed to the bracket, a lead screw fixed to the output shaft of the third motor, a lead screw nut threaded onto the lead screw, and the lead screw nut rotatably connected to the top of the mounting frame.

[0013] This utility model discloses the following technical effects: The coiled back plate is placed on the feed conveyor belt assembly for conveying. When it is conveyed to the bottom of the pressing conveyor belt assembly, the pressing conveyor belt assembly is lowered by the lifting bracket and the pressing belt is started. The coiled back plate is sandwiched between the feed belt and the pressing belt. Since the pressing belt and the feed belt rotate in opposite directions, the conveying direction of the top of the feed belt that contacts the coiled back plate is the same as the conveying direction of the bottom of the pressing belt. The speed of the feed belt is greater than that of the pressing belt, so that the coiled back plate will be gradually pulled open and stretched under the friction of the two belts, thereby reducing the risk of equipment downtime caused by back plate feed blockage, achieving more efficient and stable feeding, and improving the working efficiency of the crusher.

[0018] 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.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Reference Figures 1-2 This utility model provides an auxiliary feeding device for a crusher, comprising:

[0021] The downward conveyor belt assembly is used to be installed at the feed inlet of the crusher 1. The feed inlet of the crusher 1 is equipped with a feed conveyor belt assembly. The downward conveyor belt assembly is located above the feed conveyor belt assembly. The downward belt 2 in the downward conveyor belt assembly rotates in the opposite direction to the feed belt 3 in the feed conveyor belt assembly. The speed of the feed belt 3 in the feed conveyor belt assembly is greater than the speed of the downward belt 2 in the downward conveyor belt assembly.

[0022] The lifting support is installed on the crusher 1. The lifting end of the lifting support is connected to the lower conveyor belt assembly. The lifting support is used to adjust the distance between the lower conveyor belt assembly and the feed conveyor belt assembly.

[0023] In this embodiment, the crusher 1 relies on a belt to convey the feed; the downward pressure belt 2 and the feed belt 3 rotate in opposite directions, so the bottom of the downward pressure belt 2 and the top of the feed belt 3 move in the same direction, both moving towards the feed inlet of the crusher 1, thereby conveying the back plate to the feed inlet of the crusher 1; due to the speed difference between the downward pressure belt 2 and the feed belt 3, the coiled back plate will be gradually stretched out under the friction of the two belts.

[0024] In some alternative embodiments, the feed end of the crusher 1 is fixedly connected to a bottom support frame 4, the feed conveyor belt assembly includes two first rollers (not shown in the figure) rotatably connected to the bottom support frame 4, the two first rollers convey a feed belt 3, a first motor 5 is fixedly connected to the bottom support frame 4, and the output shaft of the first motor 5 is fixedly connected to either of the first rollers.

[0025] The first motor 5 drives the first roller to rotate, thereby driving the feed belt 3 to rotate on the two first rollers to realize the transmission of the back plate (the specifics are existing technology and will not be described in detail here).

[0026] In some alternative embodiments, the lifting bracket includes a mounting frame 6, a downward conveyor belt assembly is mounted on the mounting frame 6, and two connecting rods 7 are rotatably connected to both sides of the mounting frame 6. The end of the connecting rod 7 away from the mounting frame 6 is rotatably connected to the bottom support frame 4. A drive assembly is provided on the bottom support frame 4, and the drive assembly is connected to the mounting frame 6.

[0027] In some alternative embodiments, the drive assembly includes two struts fixed to the bottom support frame 4, with a bracket 8 rotatably connected between the two struts. The bracket 8 is located above the mounting frame 6, and a third motor 9 is fixed to the bracket 8. A lead screw 10 is fixed to the output shaft of the third motor 9, and a lead screw nut is threaded onto the lead screw 10. The lead screw nut is rotatably connected to the top of the mounting frame 6.

[0028] When the third motor 9 starts, the screw nut and the screw 10 rotate, causing the screw nut to move up and down along the screw 10, thereby driving the connecting rod 7 to rotate and the mounting frame 6 to rise and fall, thus realizing the adjustment of the distance between the feed belt 3 and the pressure belt 2.

[0029] In some alternative embodiments, the pressure conveyor belt assembly includes two second rollers rotatably connected to the mounting frame 6, on which the pressure belt 2 is conveyed. A second motor 11 is fixedly connected to one side of the mounting frame 6, and the output shaft of the second motor 11 is fixedly connected to either of the second rollers.

[0030] In this embodiment, both the second motor 11 and the first motor 5 have speed regulation functions, with a speed range of 0.3-1.8 m / s. The initial gap between the pressing belt 2 and the feeding belt 3 is determined based on the maximum curling diameter of the coiled back plate, generally between 100-200 mm, and can be dynamically adjusted during operation according to the actual curling situation of the back plate. The gap between the pressing belt 2 and the feeding belt 3 is adjusted by the pressing cylinder 9. When the pressing belt 2 moves downward and approaches the feeding belt 3, it can squeeze the coiled back plate.

[0031] The stretching of the coiled backplate is achieved by controlling the speed difference between the feed belt 3 and the pressure belt 2. When the speed of the feed belt 3 is greater than that of the pressure belt 2, the coiled backplate will gradually be stretched out under the friction of the two belts. The adjustment range of the speed difference is determined according to the material of the backplate and the degree of coiling, and is generally controlled between 0.1-0.5 m / s. During the operation of the device, the shape of the backplate and the feeding situation can be monitored in real time by sensors, and the feedback signal is sent to the control system to automatically adjust the belt speed difference to achieve the best stretching effect.

[0032] The specific operating procedure is as follows:

[0033] The rolled back plate is placed at the starting end of the feed belt 3. The first motor 5 of the feed belt 3 is started, and the speed of the feed belt 3 is initially set to 1m / s, so that the back plate begins to be conveyed forward on the feed belt 3.

[0034] When the back plate approaches the extrusion area of ​​the feed belt 3 and the pressing belt 2, the height of the pressing belt 2 is adjusted by the third motor 9 according to the degree of curling of the back plate, so that the gap between the pressing belt 2 and the feed belt 3 is slightly smaller than the curling diameter of the back plate, for example, set to 80mm; at the same time, the second motor 11 of the pressing belt 2 is started, with the initial speed set to 0.6m / s; when the back plate enters the extrusion area, the pressing belt 2 further reduces its height.

[0035] The system can monitor the shape changes of the back plate in the extrusion zone and the feeding situation in real time using sensors. When it is found that the back plate has not been effectively stretched, the control system gradually increases the speed difference between the feed belt 3 and the pressure belt 2 according to a preset algorithm. Through the action of friction, the back plate is gradually stretched into a planar shape. After being extruded and stretched, the back plate is driven by the feed belt 3 and accurately enters the gap between the pressure rollers at the feed inlet of the crusher 1 along the guide plate, completing the feeding process.

[0036] Throughout the entire operation, the speed and belt gap of the feed belt 3 and the pressure belt 2 can be adjusted at any time according to the amount of scrap photovoltaic modules processed on the production line and the actual feeding situation of the backsheet, so as to ensure that the device is always in the best working condition.

[0037] This application has the following advantages:

[0038] 1. High-efficiency feeding: It can effectively solve the feeding problem of the back plate of the crusher, avoid equipment downtime caused by feeding blockage, greatly increase the effective working time of the crusher, and improve the feeding efficiency by more than 50% compared with traditional devices.

[0039] 2. Strong material adaptability: It can adapt to back plates with different degrees of curling, different materials and sizes. By adjusting parameters such as belt gap and speed difference, it can ensure that various types of curled back plates can enter the crusher smoothly, thus expanding the processing capacity of the entire waste photovoltaic module recycling production line for different products.
