Description

Technical Field

[0001] This invention relates to the field of plastic waste recycling technology, and in particular to an automated recycling device for hyaluronic acid epoxy resin waste. Background Technology

[0002] With the rapid development of the electronics industry, the amount of waste epoxy resin-encapsulated chips has increased dramatically. Epoxy resin is widely used in high-end chip packaging due to its excellent heat resistance and mechanical strength, but its highly cross-linked structure makes recycling extremely difficult. Traditional recycling methods mainly rely on mechanical crushing, that is, directly crushing the waste material with crushing rollers. This crushing method results in impurities such as chip metal leads and silicon substrates being mixed with epoxy resin powder in the crushed waste material, leading to a large number of impurities in the crushed waste material. This results in low quality epoxy resin recycling and affects the recycling rate of epoxy resin. Summary of the Invention

[0003] In order to overcome the shortcomings pointed out in the background art above, the present invention provides an automated recycling device for hydantoin epoxy resin waste.

[0004] The technical solution of the present invention is: an automated recycling device for epoxy resin waste, comprising a shell, the shell having a feed inlet, a first guide plate and a second guide plate fixedly connected inside the shell, a crushing component disposed inside the shell for crushing the epoxy resin waste, a baffle fixedly connected to the shell above the second guide plate, a first electromagnetic slide rail disposed on the shell, a first electromagnetic slider slidably connected inside the first electromagnetic slide rail, a pressing plate fixedly connected to the first electromagnetic slider near the baffle, a second electromagnetic slide rail disposed on the shell, a second electromagnetic slider slidably connected to the second electromagnetic slider, and a pressing frame fixedly connected to the second electromagnetic slider near the second guide plate.

[0005] Furthermore, the crushing assembly includes a first motor mounted on the housing. Two symmetrically distributed first rotating rollers are rotatably connected inside the housing. One of the first rotating rollers passes through the housing and is fixedly connected to the output shaft of the first motor. The two first rotating rollers are driven by a first gear set. A second motor is mounted on the housing. Two symmetrically distributed second rotating rollers are rotatably connected inside the housing. One of the second rotating rollers passes through the housing and is fixedly connected to the output shaft of the second motor. The two second rotating rollers are driven by a second gear set.

[0006] Furthermore, the second guide plate is attached to the extrusion frame, and there is a distance between the baffle and the extrusion plate.

[0007] Furthermore, a vibrating plate is fixedly connected inside the outer shell, the vibrating plate is provided with a plurality of filter holes, a vibrating motor is installed in the outer shell, the output shaft of the vibrating motor is fixedly connected to the vibrating plate, and the first guide plate and the second guide plate are both in contact with the vibrating plate.

[0008] Furthermore, a plurality of guide rods are fixedly connected inside the housing, all of which are located between the first guide plate and the second guide plate. The first motor and the first rotating roller are both located between the first guide plate and the second guide plate. The plurality of guide rods are all located above the two first rotating rollers, and the two second rotating rollers are all located below the filter holes on the vibrating plate.

[0009] Furthermore, there is a distance between the second guide plate and the filter holes of the vibrating plate.

[0010] Furthermore, the distance between the two first rotating rollers is X, and the distance between the two second rotating rollers is Y, where X > Y.

[0011] Furthermore, the first rotating roller is fixedly connected to a plurality of extrusion rollers spaced apart, the extrusion rollers being made of a flexible material.

[0012] Furthermore, the extrusion wheels on the different first rotating rollers are misaligned.

[0013] Furthermore, the axis of the extrusion roller is misaligned with the axis of the adjacent first rotating roller.

[0014] The beneficial effects of the present invention using the above structure are as follows: The present invention uses an extrusion plate and an extrusion frame to drive one side of the waste material to move back and forth, causing the waste material to be continuously bent and the epoxy resin on the waste material to be continuously broken and detached, thereby improving the efficiency of epoxy resin recycling. Furthermore, the waste material is not directly crushed, thus reducing the content of impurities in the recycled epoxy resin and improving the quality of epoxy resin recycling. Before bending the waste material, several guide rods are used to guide the waste material between two first rotating rollers, and then the two first rotating rollers squeeze the waste material, squeezing the surface of the waste material without squeezing the sides. This allows the waste material to pass between the two first rotating rollers under pressure without being crushed, causing the epoxy resin on the waste material to break or even detach from the waste material, thereby improving the efficiency of epoxy resin recycling. Moreover, when the waste material passes between the two first rotating rollers, several extrusion rollers, spaced apart and eccentrically arranged on different first rotating rollers, squeeze the waste material, causing it to bend under pressure, improving the detachment effect of the epoxy resin on the waste material, thereby improving the efficiency of epoxy resin recycling.

Detailed Implementation

[0023] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] An automated recycling device for hydantoin epoxy resin waste, such as Figures 1-6As shown, the device includes a housing 1, which has a control terminal (not shown in the figure). The upper part of the housing 1 has a feed inlet 101, and the lower left side of the housing 1 has a recycling port for discharging the crushed epoxy resin. A first guide plate 2 and a second guide plate 3 are fixed inside the housing 1. The inner bottom surface of the housing 1, the first guide plate 2, and the second guide plate 3 are all inclined. The first guide plate 2 gradually tilts to the left from top to bottom, and the second guide plate 3 gradually tilts to the right from top to bottom. The inner bottom surface of the housing 1 gradually tilts to the left from top to bottom. When waste material (i.e. containing epoxy resin)... Waste epoxy resin (encapsulated chips) falls onto the first guide plate 2 through the feed inlet 101. The waste moves along the upper surface of the first guide plate 2 until it falls onto the second guide plate 3. A crushing assembly 4 is installed inside the outer casing 1. During the process of the waste falling from the first guide plate 2 onto the second guide plate 3, the waste passes through the crushing assembly 4, which crushes and squeezes the epoxy resin waste. A baffle 5 is fixed to the outer casing 1, located above the second guide plate 3. The distance between the baffle 5 and the second guide plate 3 is used to allow the waste to pass through. The outer casing 1 is electrically connected to a control terminal. The housing 1 is connected to a first electromagnetic slide rail, and a first electromagnetic slider 6 is slidably connected inside the first electromagnetic slide rail. A pressing plate 7 is fixedly connected to the first electromagnetic slider 6 near the baffle 5. The first electromagnetic slider 6 drives the pressing plate 7 to move up and down reciprocally. The housing 1 is provided with a second electromagnetic slide rail electrically connected to a control terminal. A second electromagnetic slider 8 is slidably connected to the second electromagnetic slide rail of the housing 1. The number of the first electromagnetic slide rail, the first electromagnetic slider 6, the second electromagnetic slide rail, and the second electromagnetic slider 8 can all be two, distributed front and rear, to increase the stability of the movement of the pressing plate 7 and the pressing frame 9. The second electromagnetic slider 8 is fixedly connected to the extrusion frame 9 near the second guide plate 3. The rearward projection of the extrusion frame 9 is L-shaped. The second electromagnetic slider 8 is used to drive the extrusion frame 9 to move up and down reciprocally. The second guide plate 3 is in contact with the extrusion frame 9. There is a distance between the baffle 5 and the extrusion plate 7. Initially, the extrusion plate 7 is in contact with the extrusion frame 9 to block the waste material, so that one end of the waste material is located between the second guide plate 3 and the baffle 5, and the other end of the waste material is located between the extrusion plate 7 and the extrusion frame 9. When the extrusion plate 7 and the extrusion frame 9 move up and down reciprocally, the waste material is bent back and forth.

[0026] like Figures 1-3As shown, the crushing assembly 4 includes a first motor 401 electrically connected to a control terminal. The first motor 401 is mounted on a housing 1. Two first rotating rollers 402, symmetrically distributed on the left and right, are rotatably connected inside the housing 1. The right first rotating roller 402 passes through the housing 1 and is fixedly connected to the output shaft of the first motor 401. The two first rotating rollers 402 are driven by a first gear set, which consists of two spur gears, each fixedly connected to an adjacent first rotating roller 402. A second motor 403, electrically connected to a control terminal, is mounted on the housing 1. Two first rotating rollers 402, symmetrically distributed on the left and right, are rotatably connected inside the housing 1. Two second rotating rollers 404 are provided. The right second rotating roller 404 passes through the outer casing 1 and is fixedly connected to the output shaft of the second motor 403. The two second rotating rollers 404 are driven by a second gear set, which consists of two spur gears. The two spur gears are fixedly connected to the adjacent second rotating rollers 404 respectively. The distance between the two first rotating rollers 402 is X, and the distance between the two second rotating rollers 404 is Y, where X > Y. The two first rotating rollers 402 are used to squeeze the waste material, causing the epoxy resin on the waste material to fall off under pressure. The two first rotating rollers 402 are used to crush the fallen epoxy resin.

[0027] like Figure 2 and Figure 3 As shown, a vibrating plate 10 is fixedly connected inside the outer casing 1. A material collection port is provided at the rear of the outer casing 1 for collecting waste placed on the vibrating plate 10. A guide portion is provided on the upper surface of the lower part of the vibrating plate 10. The guide portion gradually slopes downward from the left and right sides towards the center. Several filter holes are provided in the middle of the guide portion on the vibrating plate 10. A vibrating motor 11 electrically connected to a control terminal is installed in the outer casing 1. The output shaft of the vibrating motor 11 is fixedly connected to the vibrating plate 10. The first guide plate 2 and the second guide plate 3 are both in contact with the vibrating plate 10. When the vibrating motor 11 is turned on, the vibrating plate 10 vibrates, thereby driving the first guide plate 2 and the second guide plate 3 to vibrate. There is a distance between the second guide plate 3 and the filter holes of the vibrating plate 10, so that the waste falls downward onto the vibrating plate 10 after passing through the second guide plate 3.

[0028] like Figure 2As shown, a number of guide rods 12 are fixed inside the outer casing 1. All guide rods 12 are located between the first guide plate 2 and the second guide plate 3. The guide rods 12 are used to guide the waste material between the two first rotating rollers 402 so that the waste material (i.e., the waste packaged chip with epoxy resin) falls vertically between the two first rotating rollers 402. The surface of the chip with epoxy resin faces one of the first rotating rollers 402 so that when the waste material passes between the two first rotating rollers 402, the surface of the waste material is squeezed but the sides of the waste material are squeezed. The waste material passes between the two first rotating rollers 402 under pressure but not crushed. The first motor 401 and the first rotating rollers 402 are both located between the first guide plate 2 and the second guide plate 3. The number of guide rods 12 are all located above the two first rotating rollers 402. The two second rotating rollers 404 are all located below the filter holes on the vibrating plate 10. The waste material passes sequentially between the first guide plate 2, between the two first rotating rollers 402, between the second guide plate 3, between the vibrating plate 10, and between the two second rotating rollers 404.

[0029] The specific working principle is as follows:

[0030] When this device is needed to recycle Hein epoxy resin waste, the operator adds the waste to the feed inlet 101 and starts the vibration motor 11 via the control terminal. The output shaft of the vibration motor 11 drives the vibration plate 10 to vibrate, and the vibration plate 10 drives the first guide plate 2 and the second guide plate 3 to vibrate. The waste falls onto the first guide plate 2 through the feed inlet 101. Since the first guide plate 2 is inclined and vibrating, the waste gradually moves to the left. Several guide rods 12 guide the waste together, guiding it between the two first rotating rollers 402. The first motor 401 is started via the control terminal. The output shaft of the first motor 401 drives the adjacent first rotating roller 402 to rotate. The first rotating roller 402 drives the adjacent first rotating roller 402 to rotate via the first gear set, so that the two first rotating rollers 402 rotate in opposite directions (towards...). Figure 1 The main view serves as the reference for the direction of rotation. The first rotating roller 402 on the left rotates clockwise, and the first rotating roller 402 on the right rotates counterclockwise. This squeezes the waste material located between the two first rotating rollers 402, presses the epoxy resin on the waste material, causing the epoxy resin to break or even detach from the waste material.

[0031] After the fertilizer passes between the two first rotating rollers 402, the waste falls onto the second guide plate 3. Because the second guide plate 3 is inclined and vibrating, the waste gradually moves to the right. When the right end of the waste reaches the extrusion plate 7 and the extrusion frame 9, the extrusion plate 7 and the extrusion frame 9 block the waste. The left end of the waste is located between the baffle 5 and the second guide plate 3. The first and second electromagnetic slide rails of the outer casing 1 are activated via the control terminal. The first electromagnetic slider 6 and the second electromagnetic slider 8 respectively drive the extrusion plate 7 and the extrusion frame 9 to move up and down reciprocally. The extrusion plate 7 and the extrusion frame 9 together drive the right end of the waste... The device moves up and down repeatedly. When the right end of the waste moves upward, the baffle 5 limits the left end of the waste, causing the right end of the waste to bend upward. When the right end of the waste moves downward, the second guide plate 3 limits the left half of the waste, causing the right end of the waste to bend downward. The extrusion plate 7 and the extrusion frame 9 drive the right end of the waste to move back and forth, causing the waste to bend continuously. The epoxy resin on the waste is continuously broken and detached, improving the efficiency of epoxy resin recycling. The waste is not directly crushed, so as to reduce the content of waste impurities (chip components and substrate debris) in the recycled epoxy resin, thereby improving the quality of epoxy resin recycling.

[0032] When the extrusion plate 7 and the extrusion frame 9 move the right end of the waste material up and down repeatedly, causing the waste material to be bent repeatedly, the control terminal controls the first electromagnetic slider 6 and the second electromagnetic slider 8 to move in opposite directions, so that the extrusion plate 7 and the extrusion frame 9 move in opposite directions, creating a distance between the extrusion plate 7 and the extrusion frame 9. After the waste material is bent and the epoxy resin debris falls off, the right side is no longer blocked. The waste material and epoxy resin fall downward onto the vibrating plate 10. The vibrating plate 10 blocks the waste material. With the vibration of the vibrating plate 10, the epoxy resin debris falls downward through the filter holes of the vibrating plate 10 and falls between the two second rotating rollers 404.

[0033] When epoxy resin debris falls between the two second rotating rollers 404, the operator starts the second motor 403 via the control terminal. The second motor 403 drives the adjacent second rotating roller 404 to rotate, and the second rotating roller 404 drives the adjacent second rotating roller 404 to rotate via the second gear set. The two second rotating rollers 404 rotate in opposite directions (towards...). Figure 1 The main view serves as the reference for the rotation direction. The second rotating roller 404 on the left rotates clockwise, and the second rotating roller 404 on the right rotates counterclockwise. The two second rotating rollers 404 crush the epoxy resin fragments. After the epoxy resin is crushed, the operator recovers the epoxy resin through the recovery port of the outer shell 1 and recovers the waste through the material receiving port of the outer shell 1. The above steps are repeated continuously to recover the epoxy resin on the waste.

[0034] When it is necessary to stop using this device, the operator removes the epoxy resin and waste material from the housing 1, and then shuts down the first electromagnetic slide rail, the second electromagnetic slide rail, the first motor 401, the second motor 403 and the vibration motor 11 through the control terminal.

[0035] Example 2

[0036] Based on Example 1, such as Figure 6 and Figure 7 As shown, a number of extrusion rollers 13 are fixedly connected to the first rotating roller 402 at intervals. The extrusion rollers 13 are made of flexible material. The extrusion rollers 13 on different first rotating rollers 402 are staggered. When the waste passes between two first rotating rollers 402, the extrusion rollers 13 on different first rotating rollers 402 extrude pressure on the waste, causing the waste to bend under pressure and break the epoxy resin on the waste. The axis of the extrusion roller 13 is misaligned with the axis of the adjacent first rotating roller 402. During the rotation of the two first rotating rollers 402, the magnitude of the extrusion pressure generated by all the extrusion rollers 13 on the waste is continuously changed. When the waste first enters between the left and right extrusion rollers 13, the waste is in a vertical state. As the first rotating roller 402 drives all the extrusion rollers 13 on it to rotate, the extrusion pressure generated by the left and right extrusion rollers 13 on the waste gradually increases, causing the waste to bend under pressure, improving the removal effect of epoxy resin on the waste, thereby improving the recycling efficiency of epoxy resin.

[0037] In summary, the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
