Description

Technical Field

[0002] As a special epoxy resin material, hyaluronic acid epoxy resin is widely used in the preparation of high-performance composite materials such as glass fiber winding process, extrusion and pultrusion molding process and epoxy casting materials due to its excellent heat resistance and mechanical strength. In the existing technology, hyaluronic acid epoxy resin usually becomes hard and brittle after curing, and the double-roll crusher can effectively crush the epoxy resin solids through the extrusion and shearing action between the two rollers to adapt to its high hardness. Therefore, if the glass fiber hyaluronic acid epoxy resin solids are to be recycled, the double-roll crusher is usually used to crush the glass fiber hyaluronic acid epoxy resin solids into particles within a certain particle size range, so as to achieve the purpose of recycling and reuse.

[0003] However, due to the high bonding strength between the glass fiber inside the glass fiber epoxy resin and the epoxy resin matrix, the traditional double-roll crusher is prone to solid material fragments splashing during the crushing process. The splashing solid fragments will not only cause harm to the operator, but also fall to the ground near the equipment, requiring additional cleaning operations, increasing labor costs and time costs.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1 -Attached Figure 9 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by those skilled in the art based on the embodiments of the present invention without inventive effort shall fall within the scope of protection of the present invention.

[0035] Example 1: A crushing and recovery device for epoxy resin solids. When the existing double-roll crusher crushes the glass fiber epoxy resin board, due to the high bonding strength between the glass fiber and the epoxy resin matrix, solid fragments are easily splashed when the glass fiber epoxy resin board is crushed. The splashed solid fragments will not only cause harm to the operator due to their high strength, but also scatter to the ground near the equipment, requiring additional cleaning operations, which increases the operator's working time.

[0036] Refer to the attached Figure 1 -Attached Figure 3The crushing and recycling device includes a crushing machine body 1, a crushing tooth group 2 and a guide shell 3 are arranged on the upper part of the crushing machine body 1, the crushing tooth group 2 is two crushing rollers rotating in opposite directions, and the two crushing rollers of the crushing tooth group 2 are both rotatably connected to the crushing machine body 1. The crushing machine body 1 is provided with a control box, which is used to control the rotation speed of the crushing tooth group 2. The glass fiber hyaluronic acid epoxy resin board (subsequently replaced by epoxy resin board) enters between the two crushing rollers rotating in opposite directions of the crushing tooth group 2, so that the two crushing rollers of the crushing tooth group 2 crush the epoxy resin board. The guide mechanism is set On the crushing machine body 1, the power-assisting mechanism is arranged in the guide shell 3, the guide mechanism is electrically connected to the control box, and the upper limit rotation in the guide shell 3 is connected with a plurality of first straight plates 4 located on the same side and a plurality of second straight plates 5 located on the same side. The number of the first straight plates 4 and the number of the second straight plates 5 are the same. The first straight plates 4 and the adjacent second straight plates 5 squeeze each other, the adjacent two first straight plates 4 fit together, the adjacent two second straight plates 5 fit together, the first straight plates 4 and the second straight plates 5 at the edge are both fitted with the guide shell 3, and the first straight plates 4 and the second straight plates 5 are both provided with a first elastic telescopic Rod (the first elastic telescopic rod is fixed in the guide shell 3, and the first straight plate 4 and the second straight plate 5 are only in contact with 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 jointly block the upper side of the guide shell 3. Multiple first straight plates 4 and multiple second straight plates 5 are used to adapt to epoxy resin plates of different widths. There are two sliding rods 6 connected to the guide shell 3 in a limited sliding manner. The epoxy resin plate passes through the gap between the first straight plate 4 and the second straight plate 5 and is crushed by the crushing tooth group 2. The lower part of the crusher body 1 is provided with The storage shell temporarily stores the crushed epoxy resin solid particles. Finally, the operator takes out the crushed epoxy resin solid particles from the storage shell of the crushing machine 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 plates 5 gradually decreases from top to bottom, which is convenient for guiding the epoxy resin plate into between the first straight plates 4 and the second straight plates 5.

[0037] The above arrangement can be realized. In the process of crushing the epoxy resin board, the operator first rotates the crushing tooth group 2 through the control box, and the control box starts the guide 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. According to the width of the epoxy resin board, the corresponding number of the first straight plate 4 and the second straight plate 5 are rotated, and the corresponding first elastic telescopic rod is compressed. The rotating first straight plate 4 and the second straight plate 5 (the subsequent first straight plate 4 and the second straight plate 5 refer to the rotating ones) are respectively connected to them. Under the elastic action of the first elastic telescopic rod, the epoxy resin plate is clamped and kept in a shielding state on the upper part of the guide shell 3. The epoxy resin plate entering the guide shell 3 is guided by the guide mechanism into the crushing tooth group 2 for crushing. The power assist 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 a stable state of the epoxy resin plate, shorten the gap between the first straight plate 4 and the second straight plate 5, and cooperate with the guide mechanism to transport the epoxy resin plate, ultimately achieving 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.

[0038] The guiding mechanism continuously and stably conveys the epoxy resin board to ensure the crushing efficiency of the device for the epoxy resin board. At the same time, the first straight plate 4 and the second straight plate 5 block the splashing of fragments generated by the crushing tooth group 2 when crushing the epoxy resin board, reducing the probability of physical harm to the operator caused by the splashing fragments. When the guiding mechanism completes the guidance of an epoxy resin board, the power assist mechanism is reset, and the operator places the next epoxy resin board into the guide shell 3 and repeats the above-mentioned epoxy resin board crushing operation until all the epoxy resin boards are crushed. The operator then turns off the crushing tooth group 2 and the guiding mechanism through the control panel.

[0039] Guide mechanism:

[0040] Refer to the attached Figure 1 -Attached Figure 5The motor 21 is installed on the crushing machine body 1, and two rotating shafts 22 are connected to the guide shell 3 for rotation. The two rotating shafts 22 are located above the crushing tooth group 2. The motor 21 and the rotating shaft 22 on the rear side are driven by a belt. The two rotating shafts 22 are driven by a gear set. The rotating shaft 22 matches the conveying speed of the epoxy resin board with the speed of the crushing tooth group 2 crushing the epoxy resin board through the sliding plate 23. A plurality of sliding plates 23 distributed circumferentially are slidably connected to the rotating shaft 22. Since the epoxy resin board may not enter the crushing tooth group 2 after being placed in the guide shell 3, the crushing tooth group 2 needs to rotate to guide the epoxy resin board into it, and the epoxy resin board entering between the two is moved downward and entered into the crushing tooth group 2 by the counter-rotating of the two rotating shafts 22. Due to the hardness of the epoxy resin board, the epoxy resin board will be crushed in the process of relying solely on the crushing tooth group 2 to crush the epoxy resin board. In the event of fracture and separation, the epoxy resin board will leave the middle position of the crushing tooth group 2, and it is necessary to wait for the crushing tooth group 2 to guide the epoxy resin board into the middle of it again before continuing the crushing operation. The crushing tooth group 2 is clamped and conveyed by the sliding plates 23 on the two rotating shafts 22, so that the crushing tooth group 2 continuously crushes the single epoxy resin board, which speeds up the efficiency of the device in crushing the single epoxy resin board. The number of sliding plates 23 is adaptively adjusted according to the size of the rotating shaft 22 in actual conditions. The sliding plates 23 are in an inclined state, which is used to make the sliding plates 23 squeeze the epoxy resin board and push it downward, so that the epoxy resin board is stably conveyed downward, ensuring the continuous crushing effect of the epoxy resin board by the crushing tooth group 2. The arc-shaped portion on the sliding plate 23 is used to reduce the possibility of the epoxy resin board being inserted between the corresponding rotating shaft 22 and the sliding plate 23 above it through the gap between the two sliding plates 23, and hindering the rotating shaft 22 from driving the sliding plate 23 to rotate stably.

[0041] The above setting can be realized. When the crushing tooth group 2 starts working, the control box starts the motor 21, and the motor 21 rotates the rear rotating shaft 22 counterclockwise (from right to left) through the belt. The two rotating shafts 22 rotate in opposite directions through the gear group. When the operator inserts the epoxy resin plate into the guide shell 3 through 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 squeeze the sliding plate 23 on the upper part of the rotating shaft 22 on one side. Taking the rear rotating shaft 22 as an example, the epoxy resin plate squeezes the sliding plate 23 on the upper part of the rear rotating shaft 22, and the sliding plate 23 moves downward. The sliding plate 23 compresses the second elastic telescopic rod connected to it. The arc-shaped portion on the sliding plate 23 prevents the epoxy resin plate from being inserted between the two adjacent sliding plates 23. As the rotating shaft 22 rotates, the inclined sliding plate 23 assists in inserting the epoxy resin plate Pushed between the two rotating shafts 22, the two rotating shafts 22 squeeze and clamp the epoxy resin plate through the sliding plates 23 thereon and transport the epoxy resin plate downward. Afterwards, the two sliding rods 6 enable the first straight plate 4 and the second straight plate 5 to clamp the epoxy resin plate. Combined with the operation of the sliding plates 23 clamping the epoxy resin plate, the epoxy resin plate is kept in a vertical state and gradually transported into the crushing tooth group 2, thereby reducing the probability of the epoxy resin plate breaking and detaching from the crushing tooth group 2 during the crushing process of the crushing tooth group 2, and ensuring the continuous crushing effect of the crushing tooth group 2 on a single epoxy resin plate. The sliding plate 23 at the gap between the two rotating shafts 22 moves when squeezing the epoxy resin plate and drives the corresponding sliding plate 23 to move synchronously through the arc-shaped portion on it. When the sliding plate 23 loses contact with the epoxy resin plate, the sliding plate 23 moves and resets under the elastic force of the second elastic telescopic rod connected to it.

[0042] Supporting organizations:

[0043] Refer to the attached Figure 3 , Attachment Figure 6 and attached Figure 7, the two fixed cylinders 31 are both installed on the guide shell 3, the telescopic end of the fixed cylinder 31 is slidably connected to the sliding sleeve 32, and a spring is fixed between the sliding sleeve 32 and the telescopic end of the adjacent fixed cylinder 31. The two sliding curved rods 41 are both slidably connected to the guide shell 3, and a tension spring is fixed between the sliding curved rod 41 and the guide shell 3. A shield is provided at the sliding connection between the sliding curved rod 41 and the guide shell 3 to reduce the probability of dust or debris in the guide shell 3 flying out from the sliding connection between the sliding curved rod 41 and the guide shell 3. The laser ranging sensor 42 is located outside the guide shell 3. This device is When not in use, the tension spring connected to the sliding bent rod 41 is in a stretched state, the elastic coefficient of the second elastic telescopic rod connected to the sliding plate 23 is greater than the elastic coefficient of the tension spring at the sliding bent rod 41, and the sliding bent rod 41 is L-shaped. When the sliding rod 6 does not assist in squeezing the first straight plate 4 and the second straight plate 5, the maximum thickness of the epoxy resin board that can be supported by the first straight plate 4 and the second straight plate 5 in combination with the first elastic telescopic rod is set to a set value. The sliding bent rod 41 is always in contact with the adjacent sliding plate 23, and the thickness of the epoxy resin board is obtained according to the changes in data detected by the laser ranging sensor 42.

[0044] The above arrangement can be realized. When the epoxy resin plate enters between the two rotating shafts 22 and is squeezed and conveyed downward by the sliding plate 23, the two rotating shafts 22 drive all the sliding plates 23 thereon to rotate synchronously. The minimum gap between the two sliding plates 23 at the symmetry line of the two rotating shafts 22 is the thickness of the epoxy resin plate. The two sliding curved rods 41 move away from each other under the tension of the tension spring connected thereto. The thickness of the epoxy resin plate is calculated based on the change in the data detected by the laser ranging sensor 42 on the sliding curved rod 41. If the thickness of the epoxy resin plate exceeds the set value, the control box The telescopic ends of the two electric push rods 31 are started to fully extend and 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 squeeze the first straight plate 4 and the second straight plate 5. As the telescopic ends of the electric push rods 31 are extended, the springs between the telescopic ends of the electric push rods 31 and the sliding sleeves 32 are compressed. Under the action of the elastic force of the springs connected to the two sliding sleeves 32, the two sliding rods 6 assist the first straight plate 4 and the second straight plate 5 to clamp and straighten the epoxy resin plate (so that the epoxy resin plate becomes vertical).

[0045] When the epoxy resin plate between the two rotating shafts 22 loses contact with all the sliding plates 23, the sliding plate 23 moves and resets under the elastic force of the second elastic telescopic rod connected to it, and at the same time, the sliding plate 23 pushes the sliding bent rod 41 to move and reset, and the sliding bent rod 41 stretches the tension spring connected to it. The laser ranging sensor 42 on the sliding bent rod 41 detects that the distance becomes smaller, and the control box controls the telescopic ends of the two electric push rods 31 to be completely retracted and closed. The sliding sleeve 32 loses contact with the corresponding sliding rod 6. At the same time, the sliding sleeve 32 restores its relative position with the telescopic end of the electric push rod 31 under the elastic force of the spring connected to it, and the two sliding rods 6 stop squeezing the first straight plate 4 and the second straight plate 5. At this point, all parts in the device return to their initial positions, and the operator continues to put in the next epoxy resin plate to perform the above-mentioned crushing operation.

[0046] Example 2: This example discloses a crushing and recovery device for hyaluronic acid epoxy resin solids. Based on Example 1, when the epoxy resin is crushed, glass fiber fragments will be splashed. The tiny fragments in the splashed glass fiber fragments are easily suspended in the air. With the continuous crushing of the epoxy resin board, the concentration of the glass fiber fragments in the material guide shell 3 will gradually increase. When the first straight plate 4 and the second straight plate 5 release the obstruction on the upper side of the material guide shell 3, the glass fiber fragments in the material guide shell 3 will diffuse into the air with the gas, polluting the working environment of the operator and threatening the life safety of the operator.

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

[0048] Refer to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 8 and attached Figure 9, the silica gel balls in the air guide shell 74 are hydrophobic modified silica gel, which are used to reduce the silica gel ball's adsorption effect on dust and ensure the silica gel ball's stable adsorption of glass fiber fragments. The air pump 76 is electrically connected to the control box. The air guide pipe 72 is a multi-way pipe. There are multiple connecting holes at different positions between the air guide pipe 72 and the material guide shell 3, which are used to fully extract the gas, dust and suspended glass fiber fragments in the material guide shell 3. After the air pump 76 is started, the air flow carries the dust and glass fiber fragments through the air guide pipe 72, the air guide shell 74, the air pipe 73 and the filter cartridge 75 and is discharged from the air pump 76, and the outside air The air enters the material guide shell 3 through the gap between the first straight plate 4 and the second straight plate 5, so that the air flow in the material guide shell 3 flows in one direction, effectively removing the dust and glass fiber fragments suspended in the material guide shell 3. A filter bag is provided in the filter cartridge 75 to remove the dust extracted from the material guide shell 3. The silica gel in the air guide shell 74 absorbs the glass fiber fragments, reducing the total amount of glass fiber fragments filtered by the filter bag in the filter cartridge 75, thereby ensuring the service life of the filter bag in the filter cartridge 75 (when the glass fiber fragments are filtered by the filter bag in the filter cartridge 75, the limiting structure of the filter bag will be destroyed, thereby reducing the service life of the glass fiber).

[0049] The above setting can be realized. When the operator starts the motor 21 through the control box, the operator synchronously starts the air pump 76 through the control box. The dust and glass fiber fragments generated by the crushing tooth group 2 crushing the epoxy resin board enter the air guide shell 74 with the air flow through the air guide pipe 72. The air flow carries the dust and glass fiber fragments and moves irregularly in the gaps between the silicone balls in the air guide shell 74. The glass fiber fragments carry kinetic energy and insert into the silicone balls and are adsorbed by the silicone balls. The dust follows the air flow through the gaps between the silicone balls and the air supply pipe 73 and is filtered by the filter bag in the filter cartridge 75. The filtered gas is discharged through the air pump 76. When the operator completes the crushing of all the epoxy resin boards, the operator turns off the crushing tooth group 2, the motor 21 and the air pump 76 through 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 regularly to ensure the separation effect of the glass fiber fragments.
