Description

Technical Field

[0001] This utility model belongs to the technical field of crushing and recycling equipment, and in particular relates to a crushing and recycling device for glass substrates of waste liquid crystal displays. Background Technology

[0002] Glass substrates are an important component of LCD screens. To save resources, it is necessary to recycle and reuse the glass substrates from waste LCD screens. Currently, the existing recycling method usually involves first dismantling the waste LCD screen to obtain the whole glass substrate, then crushing the glass substrate into small pieces, and then grinding the small pieces of glass substrate into granules for reuse in a kiln.

[0003] However, some existing crushing equipment directly feeds the entire glass substrate into the crushing equipment for crushing. As the glass substrate falls, it is only crushed once when it passes the crushing position of the crushing equipment. Therefore, to ensure the crushing effect, the glass substrate sometimes needs to be repeatedly fed into the crushing equipment after it has fallen. This is inconvenient to use. Therefore, the existing technology still has shortcomings and deficiencies. Utility Model Content

[0004] The purpose of this invention is to provide a device for crushing and recycling waste liquid crystal display glass substrates to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows: A device for crushing and recycling glass substrates of waste liquid crystal displays includes a crushing box that is vertically distributed and open at both the top and bottom. The bottom opening of the crushing box is connected to a material discharge pipe, and multiple vertically opposite support legs are installed outside the bottom opening of the crushing box. A horizontally arranged material support plate is installed inside the top of the crushing box, and a number of first material discharge ports are vertically opened on the material support plate. Two horizontally opposite and spaced fixed shafts are installed at the bottom of the crushing box. Two opposite crushing plates are also installed in the crushing box below the material support plate. One end of each crushing plate is sleeved on the fixed shaft and rotatably connected to the fixed shaft. The opposite sides of the two crushing plates and the crushing box can form a V-shaped crushing and feeding bin with open top and bottom ends. An electric telescopic rod is hinged between the other side of each crushing plate and the inner wall of the crushing box.

[0006] Furthermore, each crushing plate has several secondary discharge ports.

[0007] Furthermore, each crushing plate has a textured structure on its opposite sides.

[0008] Furthermore, several first material discharge ports are located in the middle of the material receiving plate.

[0009] Furthermore, the bottom of the crushing box is funnel-shaped with a wider top and a narrower bottom, and the material discharge pipe is arranged coaxially with the crushing box.

[0010] Furthermore, horizontally distributed support plates are provided below the material discharge pipe, and the support plates are respectively connected to the support legs.

[0011] Furthermore, the pulverizing chamber has a front opening, and two oppositely arranged and closable doors are installed at the front opening position of the pulverizing chamber, with a handle installed on the outer surface of each door.

[0012] Furthermore, a transparent observation window is embedded at the bottom of the front of the crushing box.

[0013] The beneficial effects of this utility model by adopting the above technical solution are as follows: In use, this invention allows the entire glass substrate to be placed on a support plate. At this point, a hand-held hammer or a striking mechanism can be used to initially crush the glass substrate. The initially crushed substrate then falls into the crushing hopper through the first discharge port, reducing the size of the substrate entering the hopper. Once a certain amount of glass substrate remains in the hopper, the extension of the electric telescopic rod moves the two crushing plates, away from the fixed shaft, closer together within the crushing chamber. Combined with the fragile nature of the glass substrate, this allows for further crushing. Because the crushing hopper is V-shaped and the two fixed shafts are positioned within the crushing chamber, the size of the crushed glass substrate falling through the bottom of the hopper is limited. For glass substrates that cannot pass through the bottom opening of the hopper, repeated extension and retraction of the electric telescopic rod allows the two crushing plates to repeatedly crush the substrate, reducing the number of times the substrate needs to be re-input into the crushing chamber, thus facilitating use.

[0016] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0017] like Figures 1 to 5 As shown, this utility model provides a glass substrate crushing and recycling device for waste liquid crystal displays, including a crushing box 3 vertically distributed and open at both the top and bottom. A discharge pipe 1 is connected to the bottom opening of the crushing box 3, which can be used to discharge the crushed glass substrates from the crushing box 3. In use, a recycling box with an open top can be placed below the discharge pipe 1 to hold the crushed glass substrates. Multiple vertically arranged support legs 10 are also installed outside the bottom opening of the crushing box 3, which together support the crushing box 3. In use, the... By fixing the position of the support leg 10, the position of the crushing and recycling device of this utility model can be fixed; a horizontally arranged material support plate 2 is installed in the top of the crushing box 3, and several first material discharge ports 21 are vertically opened on the material support plate 2. The size of the first material discharge ports 21 can be opened according to its own needs; when in use, the entire glass substrate can be placed on the material support plate 2 first. At this time, the glass substrate can be initially crushed by a hand-held hammer or equipped with a striking mechanism. Then, the glass substrate after initial crushing can fall into the crushing box 3 located below the material support plate 2 through the first material discharge ports 21.

[0018] Based on this, two horizontally opposite and spaced fixed shafts 7 are installed at the bottom of the crushing box 3. The distance between the two fixed shafts 7 can be set according to the size of the required small glass substrate. Two opposing crushing plates 5 are also installed in the crushing box 3 below the receiving plate 2. One end of each crushing plate 5 is sleeved on the fixed shaft 7 and rotatably connected to it, allowing the crushing plate 5 to rotate around the fixed shaft 7 within the crushing box 3. The gap between the two sides of the crushing plate 5 and the inner wall of the crushing box 3 is small, insufficient for larger glass substrates to pass through. Furthermore, the opposing sides of the two crushing plates 5 and the crushing box 3 form a V-shaped crushing and feeding bin 4, open at both the top and bottom. Specifically, after preliminary crushing... The glass substrate can be dropped into the crushing and feeding bin 4 through the first feeding port 21, which reduces the size of the glass substrate put into the crushing and feeding bin 4. Each crushing plate 5 is hinged to the inner wall of the crushing box 3 on the other side. Specifically, the electric telescopic rod 6 can be equipped with an electric push rod and is externally connected to a power supply and start / stop switch located outside the crushing box 3. The two sets of electric telescopic rods 6 are electrically connected to a controller to control the synchronous extension and retraction of the two sets of electric telescopic rods 6. In the initial state, the extension end of the electric telescopic rod 6 is in the retracted state. At this time, the end of the crushing plate 5 away from the fixed shaft 7 can abut against the inner wall of the crushing box 3. In addition, a rubber pad can be set on the abutment position of the crushing plate 5 and the crushing box 3 to play a buffering role.

[0019] When in use, once a certain amount of glass substrates are stored in the crushing and feeding bin 4, no new glass substrates are added to the crushing chamber 3. At this time, by extending the electric telescopic rod 6, the two crushing plates 5, located away from the fixed shaft 7, can be moved closer to each other inside the crushing chamber 3. Combined with the fragile nature of the glass substrates, the glass substrates in the crushing and feeding bin 4 can be crushed again. Since the crushing and feeding bin 4 is V-shaped and the two fixed shafts 7 are fixed in position inside the crushing chamber 3, the size of the crushed glass substrates that fall through the bottom of the crushing and feeding bin 4 can be limited. For glass substrates that cannot pass through the bottom opening of the crushing and feeding bin 4, the two crushing plates 5 can be driven to crush the glass substrates multiple times by repeatedly extending and retracting the electric telescopic rod 6. This reduces the number of times the glass substrates are put back into the crushing chamber 3 after being crushed, making it easier to use. In addition, since the two crushing plates 5 are set in a V-shape, it is also convenient for the glass substrates in the crushing and feeding bin 4 to fall.

[0020] Furthermore, such as Figures 1 to 3As shown, each crushing plate 5 is provided with several second discharge ports 51. Specifically, the size of the second discharge ports 51 can be determined according to the size of the required small glass substrate. By providing several second discharge ports 51, the position where the crushing discharge bin 4 can drop downwards can be increased, so that the glass substrate in the crushing discharge bin 4 can be dropped. In addition, each crushing plate 5 is provided with a textured structure on the opposite side.

[0021] Furthermore, such as Figures 1 to 5 As shown, several first material discharge ports 21 are all located in the middle of the material receiving plate 2. Specifically, according to... Figure 1 For example, when the end of the crushing plate 5 away from the fixed shaft 7 abuts against the inner wall of the crushing box 3, the two crushing plates 5 are located on the left and right sides outside several first discharge ports 21 respectively. In this way, during use, it can be ensured that the glass substrates that are discharged through the first discharge ports 21 can fall onto the inclined surface of the crushing plate 5 and slide into the crushing discharge bin 4.

[0022] Furthermore, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the bottom of the crushing box 3 is funnel-shaped with a wider top and a narrower bottom. The material discharge pipe 1 is coaxially arranged with the crushing box 3, so that the glass substrate falling into the bottom of the crushing box 3 can be easily discharged during use.

[0023] Furthermore, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a horizontally distributed support plate 8 is provided below the discharge pipe 1. The support plate 8 is connected to the support leg 10. Specifically, the support plate 8 can improve the stability between the multiple support legs 10. In use, the support plate 8 can also be used to support the recycling box containing the broken glass substrate.

[0024] Furthermore, such as Figure 1 and Figure 5 As shown, the crushing chamber 3 has an opening on its front, and two opposing, openable doors 9 are installed at the opening. Specifically, the thickness of the doors 9 matches the wall thickness of the crushing chamber 3, and the opposite sides of the two doors 9 are hinged to the crushing chamber 3 via hinges to allow the doors 9 to open and close. Furthermore, a handle 11 is installed on the outer surface of each door 9 to facilitate opening and closing. Figure 1As shown, a vertically distributed baffle plate 31 is installed in the middle of the opening on the front of the crushing box 3. At this time, the thickness of the two doors 9 on opposite sides plus the thickness of the baffle plate 31 is matched with the wall thickness of the crushing box 3. The doors 9 and the baffle plate 31 are connected by a threaded rod 13 with a handle. Specifically, the threaded rod 13 is threaded to the doors 9, and the end of the threaded rod 13 away from the handle passes through the doors 9 and is threaded to the baffle plate 31 to fix the position of the doors 9 after they are closed. During use, in the cleaning stage, after opening the doors 9, tools such as an air gun can be used to easily clean the glass substrate residue remaining in the crushing box 3, the crushing plate 5, and the electric telescopic rod 6.

[0025] Furthermore, such as Figure 1 , Figure 2 and Figure 5 As shown, a transparent observation window 12 is embedded at the bottom of the front of the crushing box 3. By setting the transparent observation window 12, it is convenient to observe the actual situation of the crushed glass substrate in the crushing box 3 being discharged through the discharge pipe 1 at any time during use.
