Description

Technical Field

[0001] This invention relates to the field of epoxy resin processing technology, and specifically discloses a crushing and recycling device for solid epoxy resin. Background Technology

[0002] Hain epoxy resin, as a special epoxy resin material, is widely used in the preparation of high-performance composite materials such as glass fiber winding, pultrusion molding, and epoxy castables due to its excellent heat resistance and mechanical strength. In existing technologies, because Hain epoxy resin usually becomes hard and brittle after curing, a roller crusher can effectively break up epoxy resin solids through the squeezing and shearing action between the two rollers, adapting to its high hardness. Therefore, if glass fiber Hain epoxy resin solids are to be recycled, a roller crusher is usually used to break the glass fiber Hain epoxy resin solids into particles within a certain particle size range, thereby achieving the purpose of recycling and reuse.

[0003] However, due to the high bonding strength between the glass fibers and the epoxy resin matrix inside the glass fiber hydantoin, traditional double roller crushers are prone to the phenomenon of solid material fragments splashing during the crushing process. The splashed solid fragments not only cause injury to the operators, but also fall on the ground near the equipment, requiring additional cleaning operations, which increases labor and time costs. Summary of the Invention

[0004] To address the problem that flying fragments during the crushing of glass fiber epoxy resin can easily injure operators, this invention provides a crushing and recycling device for solid epoxy resin.

[0005] The technical solution of this invention is: a crushing and recycling device for solid hydantoin epoxy resin, comprising:

[0006] The crusher body has a crushing tooth assembly and a guide shell on its upper part. The upper part of the guide shell is rotatably connected to a plurality of first straight plates and a plurality of second straight plates on the same side. Two adjacent first straight plates are in contact with each other, and two adjacent second straight plates are in contact with each other. The edges of the first straight plates and second straight plates are in contact with the guide shell. A first elastic telescopic rod is provided between the first straight plates and the second straight plates and the guide shell. The first straight plates and adjacent second straight plates are pressed against each other. Two sliding rods are slidably connected inside the guide shell. The two sliding rods are respectively used to press against all the first straight plates and all the second straight plates.

[0007] A guiding mechanism, disposed on the crusher body, is used to assist in guiding and conveying the epoxy resin plate into the crushing tooth assembly;

[0008] An assist mechanism, located inside the material guide shell, is used to control the two sliding rods to clamp the epoxy resin board between the first straight plate and the second straight plate.

[0009] As a preferred embodiment of the present invention, the distance between the first straight plate and the adjacent second straight plate gradually decreases from top to bottom.

[0010] As a preferred embodiment of the present invention, the guiding mechanism includes a motor and two rotating shafts. The motor is mounted on the crusher body, and both rotating shafts are rotatably connected to the material guide shell. Both rotating shafts are located above the crushing tooth assembly. The motor and any one of the rotating shafts are driven by a pulley belt, and the two rotating shafts are driven by a gear set. A plurality of circumferentially distributed sliding plates are slidably connected to the rotating shafts, and a second elastic telescopic rod is fixed between the sliding plates and the corresponding rotating shafts.

[0011] As a preferred embodiment of the present invention, the sliding plate and the tangent at the edge of the corresponding rotating shaft have an angle.

[0012] As a preferred embodiment of the present invention, both sides of the sliding plate are provided with arc-shaped portions, and the two arc-shaped portions on the same sliding plate are oriented in opposite directions, and the adjacent arc-shaped portions of two adjacent sliding plates press against each other.

[0013] In a preferred embodiment of the present invention, the assist mechanism includes two electric push rods and a detection component. Both fixed cylinders are mounted on the guide shell. The telescopic ends of the fixed cylinders are slidably connected to sliding sleeves. The telescopic ends of the fixed cylinders pass through the guide shell and are slidably connected thereto. The sliding sleeves are used to push adjacent sliding rods. A spring is fixedly connected between the sliding sleeves and the telescopic ends of adjacent fixed cylinders. The detection component is disposed inside the guide shell and is used to detect whether the epoxy resin board enters between the two rotating shafts.

[0014] As a preferred embodiment of the present invention, the detection component includes:

[0015] Two sliding curved rods are slidably connected inside the material guide shell. A tension spring is fixed between the sliding curved rod and the material guide shell. The sliding curved rod is used to press the sliding plate on the adjacent rotating shaft. A laser rangefinder sensor is provided on one side of the sliding curved rod to detect the change in the distance between the two sliding curved rods.

[0016] As a preferred embodiment of the present invention, it further includes:

[0017] A gas collection mechanism, disposed on the pulverizer body, is used to handle dust and glass fiber fragments accumulated inside the feed guide shell. The gas collection mechanism includes:

[0018] An air guide shell is disposed on the crusher body. An air guide pipe and an air delivery pipe are respectively connected to both sides of the air guide shell. The air guide shell is connected to the air guide pipe. The air guide shell is filled with silicone balls. A filter cylinder and a vacuum pump are fixedly connected to the crusher body. The air delivery pipe is connected to the vacuum pump through the filter cylinder.

[0019] As a preferred embodiment of the present invention, a filter screen is provided at the connection points between the air guide shell and the air guide pipe and the air delivery pipe.

[0020] As a preferred embodiment of the present invention, the silicone balls inside the air guide shell are of different sizes, and the diameter of the silicone balls is larger than the pore size of the filter screen on the air guide shell.

[0021] Compared with the prior art, the present invention has the following advantages: 1. The present invention uses two sliding rods to squeeze the first straight plate and the second straight plate respectively. The first straight plate and the second straight plate together clamp the epoxy resin plate, so that the first straight plate and the second straight plate maintain the maximum shielding area on the upper side of the guide shell, reducing the possibility of injury to the operator caused by the flying fragments generated when the glass fiber epoxy resin breaks, and reducing the workload of the operator in cleaning.

[0022] 2. The present invention uses two rotating shafts in the guiding mechanism to drive the sliding plate to clamp and guide the epoxy resin plate downward. Combined with the first straight plate and the second straight plate clamping the epoxy resin plate, the single epoxy resin plate is continuously and stably conveyed into the crushing tooth group for crushing, thus ensuring the crushing efficiency of the epoxy resin plate.

[0023] 3. This invention reduces the probability of glass fiber fragments damaging the filter bag inside the filter cylinder by filtering glass fiber fragments through the silicone balls inside the air guide shell of the air collection mechanism, thus ensuring the service life of the filter bag inside the filter cylinder.

Detailed Implementation

[0034] The following is in conjunction with the appendix Figure 1 - Appendix Figure 9 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1: A crushing and recycling device for solid hydantoin epoxy resin. When existing roller crushers crush glass fiber hydantoin epoxy resin boards, the high bonding strength between the glass fiber and the epoxy resin matrix easily generates solid fragments that splash during crushing. These splashed solid fragments, due to their high strength, not only cause injury to operators, but also scatter on the ground near the equipment, requiring additional cleaning operations and increasing the operators' working time.

[0036] See attached document Figure 1 - Appendix Figure 3The crushing and recycling device includes a crusher body 1, with a crushing tooth assembly 2 and a guide shell 3 on the upper part of the crusher body 1. The crushing tooth assembly 2 consists of two opposing rotating crushing rollers, both of which are rotatably connected to the crusher body 1. A control box is installed on the crusher body 1 to control the rotation speed of the crushing tooth assembly 2. A glass fiber epoxy resin board (hereinafter replaced by an epoxy resin board) is inserted between the two opposing rotating crushing rollers of the crushing tooth assembly 2, causing the two crushing rollers of the crushing tooth assembly 2 to crush the epoxy resin board. A guiding mechanism is provided. On the crusher body 1, an assist mechanism is set inside the guide shell 3. The guide mechanism is electrically connected to the control box. The upper limit rotatable connection inside the guide shell 3 is provided with multiple first straight plates 4 and multiple second straight plates 5 located on the same side. The number of first straight plates 4 and the number of second straight plates 5 are the same. The first straight plates 4 and adjacent second straight plates 5 are pressed against each other, with two adjacent first straight plates 4 and two adjacent second straight plates 5 in contact. The edges of the first straight plates 4 and second straight plates 5 are both in contact with the guide shell 3. A first elastic telescopic mechanism is provided between the first straight plates 4 and second straight plates 5 and the guide shell 3. The first elastic telescopic rod is fixed inside the guide shell 3, and the first straight plate 4 and the second straight plate 5 only contact the adjacent first elastic telescopic rod. When the device is not working, the first straight plate 4 and the second straight plate 5 are V-shaped as a whole. Multiple first straight plates 4 and multiple second straight plates 5 together cover the upper side of the guide shell 3. Multiple first straight plates 4 and multiple second straight plates 5 are used to accommodate epoxy resin boards of different widths. There are two sliding rods 6 in the guide shell 3 for limiting sliding connection. After the epoxy resin board passes through the gap between the first straight plate 4 and the second straight plate 5, it is crushed by the crushing tooth assembly 2. The lower part of the crusher body 1 is provided with The crushed epoxy resin solid particles are temporarily stored in the storage shell. Finally, the operator takes out the crushed epoxy resin solid particles from the storage shell of the crusher body 1. The two sliding rods 6 squeeze all the first straight plates 4 and all the second straight plates 5 respectively, so that the first straight plates 4 and the second straight plates 5 cooperate to clamp the epoxy resin plate, reducing the gap formed between the first straight plates 4 and the second straight plates 5 on the upper side of the guide shell 3. The distance between the first straight plate 4 and the adjacent second straight plate 5 gradually decreases from top to bottom, which facilitates the guide epoxy resin plate to enter between the first straight plates 4 and the second straight plates 5.

[0037] The above setup enables the following process during the crushing of the epoxy resin board: First, the operator uses the control box to rotate the crushing tooth assembly 2 and activates the guiding mechanism. Then, the operator inserts the epoxy resin board between the first straight plate 4 and the second straight plate 5. The epoxy resin board enters the guide shell 3. Based on the width of the epoxy resin board, the corresponding number of the first straight plates 4 and the second straight plates 5 rotate, compressing the corresponding first elastic telescopic rods. The rotating first straight plates 4 and the second straight plates 5 (hereinafter, "first straight plate 4" and "second straight plate 5" refer to those that rotate) are respectively connected to... Under the elastic force of the first elastic telescopic rod, the epoxy resin plate is clamped and kept in a blocking state on the upper part of the guide shell 3. The epoxy resin plate that enters the guide shell 3 is guided by the guiding mechanism into the crushing tooth group 2 for crushing. The assisting mechanism pushes the first straight plate 4 and the second straight plate 5 through the two sliding rods 6, so that the first straight plate 4 and the second straight plate 5 maintain the stability of the epoxy resin plate and shorten the gap between the first straight plate 4 and the second straight plate 5. In conjunction with the guiding mechanism to convey the epoxy resin plate, the operation of keeping the epoxy resin plate in a vertical state and stably pushing the epoxy resin plate into the crushing tooth group 2 is finally achieved.

[0038] The guiding mechanism continuously and stably conveys the epoxy resin board, ensuring the crushing efficiency of the epoxy resin board. At the same time, the first straight plate 4 and the second straight plate 5 block the flying fragments generated by the crushing tooth assembly 2 during the crushing of the epoxy resin board, reducing the probability of physical injury to the operator from the flying fragments. After the guiding mechanism completes the guiding of one epoxy resin board, the assist mechanism resets, and the operator puts the next epoxy resin board into the guide shell 3. The above epoxy resin board crushing operation is repeated until all epoxy resin boards are crushed. After that, the operator shuts down the crushing tooth assembly 2 and the guiding mechanism through the control panel.

[0039] Guidance organization:

[0040] See attached document Figure 1 - Appendix Figure 5The motor 21 is mounted on the crusher body 1. Two rotating shafts 22 are rotatably connected inside the feed guide shell 3. The two rotating shafts 22 are located above the crushing tooth assembly 2. The motor 21 and the rear rotating shaft 22 are driven by a belt, and the two rotating shafts 22 are driven by a gear set. The conveying speed of the epoxy resin plate by the rotating shaft 22 through the sliding plate 23 is matched with the crushing speed of the epoxy resin plate by the crushing tooth assembly 2. Multiple circumferentially distributed sliding plates 23 are slidably connected on the rotating shaft 22. Since the epoxy resin plate may not enter the crushing tooth assembly 2 after being placed in the feed guide shell 3, the crushing tooth assembly 2 needs to rotate to guide the epoxy resin plate into it. The two rotating shafts 22 rotate in opposite directions to move the epoxy resin plate between them downward and into the crushing tooth assembly 2. Due to the hardness of the epoxy resin plate, the epoxy resin plate will be ejected during the crushing process by the crushing tooth assembly 2 alone. In the current case of breakage and separation, the epoxy resin plate will detach from the middle position of the crushing tooth assembly 2. It is necessary to wait for the epoxy resin plate to be guided back into the middle by the crushing tooth assembly 2 before the crushing operation can continue. Through the clamping and conveying of the sliding plates 23 on the two rotating shafts 22, the crushing tooth assembly 2 continuously crushes the single epoxy resin plate, which speeds up the efficiency of crushing a single epoxy resin plate. The number of sliding plates 23 is adaptively adjusted according to the actual size of the rotating shafts 22. The sliding plates 23 are in an inclined state to squeeze the epoxy resin plate and push it downward, so that the epoxy resin plate is stably conveyed downward, ensuring the continuous crushing effect of the crushing tooth assembly 2 on the epoxy resin plate. The arc-shaped part on the sliding plate 23 is used to reduce the possibility of the epoxy resin plate being inserted between the corresponding rotating shaft 22 and its upper sliding plate 23 through the gap between the two sliding plates 23, and to prevent the rotating shaft 22 from driving the sliding plate 23 to rotate stably.

[0041] The above setup enables the following: When the crushing gear group 2 starts working, the control box starts the motor 21. The motor 21 causes the rear rotating shaft 22 to rotate counterclockwise (viewed from right to left) via a belt. The two rotating shafts 22 rotate in opposite directions via a gear set. When the operator inserts the epoxy resin plate into the guide shell 3 between the first straight plate 4 and the second straight plate 5, if the epoxy resin plate is not directly inserted between the two rotating shafts 22, the epoxy resin plate will tilt and press against the upper sliding plate 23 of one rotating shaft 22. Taking the rear rotating shaft 22 as an example, the epoxy resin plate presses against the upper sliding plate 23 of the rear rotating shaft 22, causing the sliding plate 23 to move downwards. The sliding plate 23 compresses the second elastic telescopic rod connected to it. The arc-shaped part on the sliding plate 23 prevents the epoxy resin plate from being inserted between two adjacent sliding plates 23. As the rotating shaft 22 rotates, the tilted sliding plate 23 assists in pushing the epoxy resin plate... The epoxy resin plate is pushed between two rotating shafts 22. The two rotating shafts 22 squeeze and clamp the epoxy resin plate through the sliding plate 23 on them and convey the epoxy resin plate downward. Then, the two sliding rods 6 clamp the epoxy resin plate with the first straight plate 4 and the second straight plate 5. Combined with the operation of the sliding plate 23 clamping the epoxy resin plate, the epoxy resin plate is kept in a vertical state and gradually conveyed into the crushing tooth group 2. This reduces the probability of the epoxy resin plate breaking and detaching from the crushing tooth group 2 during the crushing process, and ensures the continuous crushing effect of the crushing tooth group 2 on a single epoxy resin plate. When the sliding plate 23 at the gap between the two rotating shafts 22 squeezes the epoxy resin plate, it moves and drives the corresponding sliding plate 23 to move synchronously through its upper arc part. When the sliding plate 23 loses contact with the epoxy resin plate, the sliding plate 23 moves back to its original position under the elastic force of the second elastic telescopic rod connected to it.

[0042] Supporting organizations:

[0043] See attached document Figure 3 Appendix Figure 6 and attached Figure 7Two fixed cylinders 31 are mounted on the guide shell 3. A sliding sleeve 32 is slidably connected to the telescopic end of the fixed cylinder 31. A spring is fixed between the sliding sleeve 32 and the telescopic end of the adjacent fixed cylinder 31. Two sliding bent rods 41 are slidably connected inside the guide shell 3. A tension spring is fixed between the sliding bent rod 41 and the guide shell 3. A shield is provided at the sliding connection point between the sliding bent rod 41 and the guide shell 3 to reduce the probability of dust or debris flying out from the sliding connection point of the sliding bent rod 41 and the guide shell 3. The laser rangefinder 42 is located outside the guide shell 3. This device... When not in use, the spring connected to the sliding bend rod 41 is in a stretched state, and the elastic coefficient of the second elastic telescopic rod connected to the sliding plate 23 is greater than the elastic coefficient of the spring at the sliding bend rod 41. The sliding bend rod 41 is L-shaped. When the sliding rod 6 does not assist in pressing the first straight plate 4 and the second straight plate 5, the maximum thickness of the epoxy resin board that the first straight plate 4 and the second straight plate 5 can support with the first elastic telescopic rod is set to a value. The thickness of the epoxy resin board is obtained based on the changes in data detected by the laser range sensor 42, since the sliding bend rod 41 is always in contact with the adjacent sliding plate 23.

[0044] The above setup enables the epoxy resin board to rotate synchronously when it enters between the two rotating shafts 22 and is squeezed and conveyed downwards by the sliding plate 23. The minimum gap between the two sliding plates 23 at the line of symmetry of the two rotating shafts 22 is equal to the thickness of the epoxy resin board. The two sliding bending rods 41 move away from each other under the tension of the springs connected to them. The thickness of the epoxy resin board is calculated based on the changes in data detected by the laser ranging sensor 42 on the sliding bending rods 41. If the thickness of the epoxy resin board exceeds the set value, the control box... When the telescopic ends of the two electric push rods 31 are fully extended, they are then closed. During the extension of the telescopic ends of the electric push rods 31, the sliding sleeves 32 contact and push the corresponding sliding rods 6. The two sliding rods 6 press against the first straight plate 4 and the second straight plate 5. As the telescopic ends of the electric push rods 31 extend, the spring between the telescopic ends of the electric push rods 31 and the sliding sleeves 32 is compressed. Under the elastic force of the two sliding sleeves 32 and the springs connected to them, the two sliding rods 6 assist the first straight plate 4 and the second straight plate 5 in clamping and straightening the epoxy resin board (making the epoxy resin board vertical).

[0045] When the epoxy resin plate between the two rotating shafts 22 loses contact with all the sliding plates 23, the sliding plates 23 move back to their original position under the elastic force of the second elastic telescopic rod connected to them. At the same time, the sliding plates 23 push the sliding bent rod 41 to move back to its original position. The sliding bent rod 41 stretches the tension spring connected to it. The laser rangefinder 42 on the sliding bent rod 41 detects that the distance has decreased. The control box controls the telescopic ends of the two electric push rods 31 to retract completely and close. The sliding sleeve 32 loses contact with the corresponding sliding rod 6. At the same time, the sliding sleeve 32 returns to its relative position with the telescopic end of the electric push rod 31 under the elastic force of the spring connected to it. The two sliding rods 6 stop pressing the first straight plate 4 and the second straight plate 5. At this point, all parts in the device return to their initial position, and the operator continues to put in the next epoxy resin plate to perform the above crushing operation.

[0046] Example 2: This example discloses a crushing and recycling device for solid epoxy resin. Based on Example 1, when epoxy resin is crushed, glass fiber fragments will splash. The tiny fragments in the splashed glass fiber fragments are easily suspended in the air. As the epoxy resin board is continuously crushed, the concentration of glass fiber fragments in the feed shell 3 will gradually increase. When the first straight plate 4 and the second straight plate 5 remove the obstruction on the upper side of the feed shell 3, the glass fiber fragments in the feed shell 3 will diffuse into the air with the gas, polluting the working environment of the operators and threatening the life safety of the operators.

[0047] The specific structure, connection relationship and working process of the components in Example 1 will not be described again.

[0048] See attached document Figure 1 Appendix Figure 2 Appendix Figure 8 and attached Figure 9The silica gel balls inside the air guide shell 74 are made of hydrophobic modified silica gel to reduce the adsorption effect of the silica gel balls on dust and ensure the stable adsorption of glass fiber fragments. The vacuum pump 76 is electrically connected to the control box. The air guide pipe 72 is a multi-port pipe with multiple connecting holes at different positions between the air guide pipe 72 and the material guide shell 3, which are used to comprehensively extract gas, dust, and suspended glass fiber fragments inside the material guide shell 3. After the vacuum pump 76 is started, the airflow carrying dust and glass fiber fragments passes through the air guide pipe 72, air guide shell 74, air delivery pipe 73, and filter cartridge 75 before being discharged from the vacuum pump 76, allowing outside air to pass through. The airflow enters the guide shell 3 through the gap between the first straight plate 4 and the second straight plate 5, causing the airflow inside the guide shell 3 to flow in one direction, effectively removing suspended dust and glass fiber fragments inside the guide shell 3. A filter bag is installed inside the filter cylinder 75 to remove the dust extracted from the guide shell 3. Silica gel in the air guide shell 74 adsorbs glass fiber fragments, reducing the total amount of glass fiber fragments filtered by the filter bag inside the filter cylinder 75 and ensuring the service life of the filter bag inside the filter cylinder 75 (when glass fiber fragments are filtered by the filter bag inside the filter cylinder 75, the limiting structure of the filter bag will be damaged, which will lead to a reduction in the service life of the glass fiber).

[0049] The above setup enables the following: when the operator starts motor 21 via the control box, the operator simultaneously starts the vacuum pump 76 via the control box. The dust and glass fiber fragments generated by the crushing tooth assembly 2 in crushing the epoxy resin board are carried by the airflow through the air guide pipe 72 into the air guide shell 74. The airflow carrying the dust and glass fiber fragments moves irregularly within the gaps of the silicone balls in the air guide shell 74. The glass fiber fragments, carrying kinetic energy, insert into the silicone balls and are adsorbed by them. The dust is carried by the airflow through the gaps of the silicone balls and the air delivery pipe 73 and filtered by the filter bag in the filter cartridge 75. The filtered gas is discharged through the vacuum pump 76. After the operator has finished crushing all the epoxy resin boards, the operator turns off the crushing tooth assembly 2, motor 21, and vacuum pump 76 via the control box. As the epoxy resin boards are continuously crushed, the silicone balls in the air guide shell 74 and the filter bags in the filter cartridge 75 are replaced periodically to ensure the separation effect of the glass fiber fragments.
