Description
Technical Field
[0001] This utility model relates to the field of ABS particle production technology, and in particular to a screening device for ABS particle production. Background Technology
[0002] ABS granules, as a thermoplastic polymer material structure with high strength, good toughness and easy processing and molding, are widely used in injection molding industry production.
[0003] In the production process, screening ABS particles of different diameters is an essential step, usually accomplished by screening plates. However, when the screening criteria change, the screening plates often need to be replaced to screen out particles that meet the new diameter requirements. However, most existing screening devices use numerous screws to fix the screening plates in place. This installation method is extremely inconvenient when replacing the screening plates, consumes a lot of time and manpower, and seriously affects production efficiency.
[0004] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: Traditional screening plate fixing methods mostly use screws to fix the screening plate to the support frame. When replacing the screening plate, it is necessary to use screwdrivers and other tools to tighten the fixing, which is cumbersome, time-consuming and labor-intensive. In the process of repeatedly disassembling and reassembling the screws, stripping is easy to occur, which increases the maintenance cost and difficulty. Therefore, in order to solve the above problems, a screening device for ABS granule product production is proposed. Utility Model Content
[0005] The purpose of this utility model is to solve the problems in the existing technology, where the traditional screening plate fixing method mostly uses screws to fix the screening plate to the support frame. When replacing the screening plate, it is necessary to use screwdrivers and other tools to tighten the fixing, which is cumbersome, time-consuming and labor-intensive. In addition, the screws are prone to stripping during repeated disassembly and reassembly, which increases the maintenance cost and difficulty. Therefore, a screening device for ABS granule product production is proposed.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a screening device for ABS granule product production, comprising a support frame, a disassembly device provided on the surface of the support frame, the disassembly device comprising two U-shaped plates, the U-shaped plates being fixedly connected to the surface of the support frame, a screening plate being slidably connected to the inner surface of the U-shaped plates, a short rod being fixedly connected to the surface of the U-shaped plates, an elliptical block being fixedly connected to one end of the short rod, a movable plate being rotatably connected to the arc surface of the short rod, a movable hole being opened on the surface of the movable plate, a shaped rod being slidably connected to the inner wall of the movable hole of the movable plate, the shaped rod being fixedly connected to the surface of the U-shaped plates, a collection plate being fixedly connected to the surface of the support frame, the collection plate being located below the screening plate, a vibration motor being fixedly connected to the lower surface of the collection plate, and a placement hopper being fixedly connected to the surface of the support frame.
[0007] The aforementioned components achieve the following effect: by setting up a disassembly device, the screening plate can be quickly disassembled and replaced. This avoids the cumbersome, time-consuming, and labor-intensive process of fixing the screening plate to the support frame with screws when it needs to be replaced. This is because traditional screening plate fixing methods often use screws to fix the screening plate to the support frame. When replacing the screening plate, screws and other tools are needed to tighten the fixing, which is cumbersome and time-consuming. In addition, the screws are prone to stripping during repeated disassembly and assembly, which increases maintenance costs and difficulty.
[0008] Preferably, the arc surface of the short rod is fitted with a torsion spring, and the two ends of the torsion spring are fixedly connected to the moving plate and the elliptical block, respectively.
[0009] The effect achieved by the above components is that, through the cooperation of the torsion spring moving plate and the elliptical block, when the moving plate is opened, due to the torsion force of the torsion spring itself, the worker can automatically return to the original position when releasing the moving plate.
[0010] Preferably, each of the U-shaped plates has two L-shaped plates fixedly connected to its surface, and the width between the two L-shaped plates is adapted to the width of the screening plate.
[0011] The effect achieved by the above components is that, through the cooperation of the L-shaped plate and the U-shaped plate, the surface of the U-shaped plate can be quickly positioned when installing the screening plate, which facilitates installation.
[0012] Preferably, a plurality of semicircular blocks are fixedly connected to the surfaces of both L-shaped plates, and the semicircular blocks are made of rubber.
[0013] The effect achieved by the above components is that the cooperation between the semi-circular L-shaped plate and the screening plate makes it easier for workers to disassemble the screening plate and reduces friction between the screening plate and the L-shaped plate.
[0014] Preferably, the surface of the support frame is provided with an auxiliary device, which includes two mounting blocks. The mounting blocks are fixedly connected to the surface of the support frame, and a round rod is fixedly connected to one side of the two mounting blocks that are close to each other. A cover plate is rotatably connected to the arc surface of the round rod.
[0015] The aforementioned components achieve the following effects: by setting up auxiliary devices, when the user is not using the placement container, the sealing method can prevent dust and other foreign objects from entering the placement container, and can also prevent the particles in the placement container from being shaken out during the working process, thus improving the practicality of the device.
[0016] Preferably, the surface of the cover plate is fixedly connected with a hook and loop fastener, and a hook and loop fastener flat surface is attached to the surface of the hook and loop fastener, which is fixedly connected to the surface of the placement hopper.
[0017] The effect achieved by the above components is that, through the cooperation of the hook and loop side and the hook and loop flat side, the cover can be glued to the surface of the opposite container when not in use, preventing the cover from being opened when not in use.
[0018] Preferably, two upright blocks are fixedly connected to the surface of the cover plate, and a flat plate is fixedly connected to the surface of each upright block.
[0019] The effect achieved by the above components is that, through the cooperation of the cover plate uprights and the flat panel, it is convenient for staff to open the cover plate.
[0020] In summary, the beneficial effects of this utility model are as follows:
[0021] 1. In this utility model, by setting a disassembly device, the screening plate can be quickly disassembled and replaced. This avoids the situation where, when it is necessary to replace the screening plate, the traditional method of fixing the screening plate to the support frame with screws is required. When replacing the screening plate, tools such as screwdrivers are needed to tighten the screws. The operation process is cumbersome, time-consuming and labor-intensive. In addition, the screws are prone to stripping during repeated disassembly and reassembly, which increases the maintenance cost and difficulty.

In this utility model, by setting an auxiliary device, the user can avoid dust and other foreign objects from entering the placement container by sealing it when the container is not in use.

[0028] Reference Figure 1 As shown, this utility model provides a technical solution: a screening device for ABS granule production, including a support frame 1. The surface of the support frame 1 is provided with a disassembly device 3. By setting the disassembly device 3, the screening plate 32 can be quickly disassembled and replaced. This avoids the cumbersome and time-consuming process of fixing the screening plate 32 to the support frame 1 with screws when it is necessary to replace the screening plate 32. This is because the traditional method of fixing the screening plate 32 is mostly to use screws to fix the screening plate 32 to the support frame 1. When replacing the screening plate 32, it is necessary to use screwdrivers and other tools to tighten the fixing. The operation process is cumbersome and time-consuming. In addition, the repeated disassembly and assembly of the screws is prone to stripping, which increases the maintenance cost and difficulty. The surface of the support frame 1 is provided with an auxiliary device 4. By setting the auxiliary device 4, when the user is not using the placement hopper 6, the dust and other foreign objects can be prevented from entering the interior of the placement hopper 6 by sealing it. It can also prevent the granules in the placement hopper 6 from shaking out during the working process, thus improving the practicality of the device.
[0029] Reference Figure 2 and Figure 3As shown in this embodiment: the disassembly device 3 includes two U-shaped plates 31, which are fixedly connected to the surface of the support frame 1. A screening plate 32 is slidably connected to the inner surface of the U-shaped plate 31. A short rod 33 is fixedly connected to the surface of the U-shaped plate 31. An elliptical block 34 is fixedly connected to one end of the short rod 33. A movable plate 35 is rotatably connected to the arc surface of the short rod 33. A movable hole is opened on the surface of the movable plate 35. A shaped rod 36 is slidably connected to the inner wall of the movable hole of the movable plate 35. The shaped rod 36 is fixedly connected to the surface of the U-shaped plate 31. A collection plate 2 is fixedly connected to the surface of the support frame 1. A vibration motor 5 is fixedly connected to the surface of the collection plate 2. A placement hopper 6 is fixedly connected to the surface of the support frame 1. A torsion spring 37 is sleeved on the arc surface of the short rod 33. The two ends of the torsion spring 37 are respectively connected to the movable plate 35 and the elliptical block. 34. Fixed connection: Two L-shaped plates 38 are fixedly connected to the surface of the U-shaped plate 31. The width between the two L-shaped plates 38 is adapted to the width of the screening plate 32. Several semi-circular blocks 39 are fixedly connected to the surface of the two L-shaped plates 38. The semi-circular blocks 39 are made of rubber. Through the cooperation of the torsion spring 37, the moving plate 35 and the elliptical block 34, when the moving plate 35 is opened, due to the torsion of the torsion spring 37 itself, the worker can automatically return to the original position when the moving plate 35 is released. Through the cooperation of the L-shaped plate 38 and the U-shaped plate 31, the screening plate 32 can be quickly positioned on the surface of the U-shaped plate 31, which is convenient for installation. Through the cooperation of the semi-circular block 39, the L-shaped plate 38 and the screening plate 32, the worker can easily disassemble the screening plate 32 and reduce the friction between the screening plate 32 and the L-shaped plate 38.
[0030] Reference Figure 4 As shown, specifically, the auxiliary device 4 includes two mounting blocks 41, which are fixedly connected to the surface of the support frame 1. A round rod 42 is fixedly connected to one side of the two mounting blocks 41 that is close to each other. A cover plate 43 is rotatably connected to the arc surface of the round rod 42. A hook and loop fastener 44 is fixedly connected to the surface of the cover plate 43. A hook and loop fastener flat surface 45 is pasted on the surface of the hook and loop fastener 44. The hook and loop fastener flat surface 45 is fixedly connected to the surface of the placement hopper 6. Two upright blocks 46 are fixedly connected to the surface of the cover plate 43. A flat plate 47 is fixedly connected to the surface of the upright blocks 46. Through the cooperation of the hook and loop fastener 44 and the hook and loop fastener flat surface 45, the cover plate 43 can be pasted on the surface of the placement hopper 6 when not in use, preventing the cover plate 43 from being opened when not in use. Through the cooperation of the upright blocks 46 and the flat plate 47 of the cover plate 43, it is convenient for the staff to open the cover plate 43.
[0031] Working principle: When the operator needs to disassemble the screening plate 32, the operator rotates the moving plate 35. The moving hole of the moving plate 35 disengages from the irregular rod 36, and the operator removes the screening plate 32. The operator replaces the screening plate 32, placing it on the surface of the L-shaped plate 38. The operator pushes the screening plate 32 into the inner surface of the U-shaped plate 31. During pushing, the screening plate 32 contacts the arc surface of the semi-circular block 39, reducing the friction of the screening plate 32 pushing into the inner surface of the U-shaped plate 31. The operator releases the moving plate 35, and due to the torque of the torsion spring 37, the moving plate 32 is moved... The movable plate 35 moves, and the moving hole of the movable plate 35 re-engages into the irregular rod 36, completing the replacement. By setting the disassembly device 3, the screening plate 32 can be quickly disassembled and replaced. This avoids the situation where, when it is necessary to replace the screening plate 32, the traditional method of fixing the screening plate 32 to the support frame 1 is to use screws to fix the screening plate 32 to the support frame 1. When replacing the screening plate 32, it is necessary to use screwdrivers and other tools to tighten the fixing. The operation process is cumbersome, time-consuming and labor-intensive. In addition, the repeated disassembly and reassembly of the screws is prone to stripping, which increases the maintenance cost and difficulty.
[0032] When the operator needs to open the cover plate 43 to use the placement hopper 6, the operator pulls the flat plate 47, which drives the upright block 46, which in turn drives the cover plate 43 to rotate. The cover plate 43 causes the hook and loop fastener 44 to not stick to the hook and loop fastener flat plate 45. The cover plate 43 rotates on the arc surface of the round rod 42. After the cover plate 43 is opened, the operator can use the placement hopper 6, thus completing the opening and use. By setting the auxiliary device 4, the device can prevent dust and other foreign objects from entering the placement hopper 6 when it is not in use by sealing it. It can also prevent the particles in the placement hopper 6 from being shaken out during the working process, thus improving the practicality of the device.
