The existing recycling process uses conventional crushing equipment to crush the debris. In actual operation, these long strips of debris will be drawn into and wrapped around the outside of the crushing roller during its rotation. After the long strips of debris are wrapped around the outside of the crushing roller, it will affect the crushing efficiency and even lead to problems such as uneven discharge particle size and unstable equipment operation.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] The existing recycling process uses conventional crushing equipment to crush the scraps of insulation boards. Since the scraps are mostly long strips, they are easily drawn into and entangled on the surface of the roller during the rotation of the crushing roller. The entanglement of the scraps not only affects the crushing efficiency, but also may cause uneven particle size of the output. In severe cases, it may even cause unstable equipment operation, increase the failure rate, and reduce production continuity and recycling quality. Example 1

[0023] This embodiment discloses a scrap recovery device for producing insulation boards, which is used to crush insulation board scraps.

[0024] like Figure 1-Figure 4As shown, it includes a bracket 1, which is fixedly connected to a shell 2. The top of the shell 2 is used to enter the crushed materials, and the bottom is used to discharge the crushed materials. The rear side of the shell 2 is fixedly connected to a connecting shaft, and the shell 2 is slidably connected to the sliding frame 3 through the connecting shaft. A power module for moving the sliding frame 3 is provided on the outside of the shell 2. The power module consists of a servo motor and a screw. The servo motor is fixedly connected to the shell 2, and the output shaft of the servo motor is fixedly connected to the screw. The screw is threadedly connected to the sliding frame 3 to drive the sliding frame 3 to slide up and down along the shell 2. A shielding grid 4 is provided in the shell 2. The shielding grid 4 is fixedly connected to the shell 2 in this embodiment, but is limited to this embodiment. The sliding frame 3 is rotatably connected to two pairs of symmetrically distributed rotating shafts 5. The four rotating shafts 5 are respectively located near the four corners of the sliding frame 3. Four vertical through slots are provided on the outside of the shell 2, and the rotating shaft 5 passes through the corresponding through slots of the shell 2. The breaker box 3 is a kind of special box that is fixed on the breaker box 2, and the breaker box 2 is a kind of special box that is fixed on the breaker box 2.

[0025] like Figure 3 and Figure 4 As shown, the docking assembly includes two symmetrically distributed first drive members 201, the first drive members 201 are servo motors, and the two first drive members 201 are fixedly connected to the rear side of the sliding frame 3. The output end of the first drive member 201 is fixedly connected to the first gear 202, and the rotating shaft 5 on the rear side is fixedly connected to the second gear 203. The first gear 202 is meshed with the second gear 203. The output shaft of the first drive member 201 can drive the tool holder 7 to deflect through the first gear 202, the second gear 203, the rotating shaft 5 and the sliding sleeve 6, so that the two tool holders 7 are docked or separated with each other. A shaking component for driving its own movement is provided in the sliding sleeve 6.

[0026] like Figure 1 、 Figure 2 and Figure 5As shown, the blocking assembly includes two blocking rotary plates 301, both of which are rotatably connected to the outer shell 2, and the two blocking rotary plates 301 are fitted together to block the outer shell 2, and the blocking rotary plates 301 are fixedly connected to the third gear 302, and the outer shell 2 is fixedly connected to the second driving member 303, and the second driving member 303 is an electric push rod, and the telescopic end of the second driving member 303 is fixedly connected to the rack rack 304, and the rack rack 304 is located between the two third gears 302, and all third gears 302 are engaged with the rack rack 304.

[0027] When using this device to crush the insulation board fragments, turn on the crushing module 8, make the two crushing rollers start to rotate, turn on the second driving member 303, and make the telescopic end of the second driving member 303 drive the two blocking rotary plates 301 to deflect through the third gear 302 and the rack rack 304, open the shell 2, and then the staff transports the material to the top of the shell 2 through the belt conveyor. The material falls downward from the top of the shell 2 and falls onto the shielding grid 4. Then the telescopic end of the second driving member 303 drives the two blocking rotary plates 301 to deflect in opposite directions and dock with each other through the third gear 302 and the rack rack 304, blocking the top of the shell 2, intercepting the entry of new material during the pre-cutting of the material, and preventing the material from being entangled on the knife holder 7.

[0028] After the blocking rotating plate 301 blocks the top of the shell 2, the power module is turned on, so that the power module drives the sliding frame 3 to move downward along the shell 2, and the sliding frame 3 drives the two tool holders 7 to move downward synchronously through the rotating shaft 5 and the sliding sleeve 6. At the same time, the two first driving members 201 are turned on, and the output shaft of the first driving member 201 drives the rotating shaft 5 to rotate through the first gear 202 and the second gear 203, so that the rotating shaft 5 drives the sliding sleeve 6 to rotate synchronously. After the sliding sleeve 6 drives the tool holder 7 thereon to rotate 90°, the first driving member 201 is closed, and the rotation directions of the output shafts of the two first driving members 201 are opposite, so that the two tool holders 7 are deflected 90° relative to each other. The two tool holders 7 are docked, and the two tool holders 7 after splicing continue to move downward under the drive of the sliding frame 3. The tool holder 7 contacts the material on the shielding grid 4 and finally enters the groove of the shielding grid 4. At this time, the two tool holders 7 complete the pre-cutting of the material, pre-cutting the long strip material into short strips. The cut material lacks support and continues to fall downward. After being crushed by the crushing module 8, it is discharged along the bottom of the shell 2, intercepted by the shielding grid 4, and cut by the two tool holders 7. The long strip material is pre-cut into short strips, and then crushed, reducing the probability of the crushing roller being entangled by the material, and ensuring the crushing accuracy of subsequent crushing.

[0029] After the material is pre-cut, the power module drives the sliding frame 3 to return to the original path. When the sliding frame 3 drives the two tool holders 7 to the docking position through the rotating shaft 5 and the sliding sleeve 6, the output shafts of the two first driving members 201 rotate in the opposite direction through the first gear 202 and the second gear 203, so that the rotating shaft 5 drives the tool holder 7 to reset and deflect 90° through the sliding sleeve 6, so that the two tool holders 7 are separated and parallel to the side walls of the shell 2. Then the telescopic end of the second driving member 303 drives the two blocking rotary plates 301 to rotate through the rack rack 304 and the third gear 302, releasing the blockage of the shell 2, so that the material at the top of the shell 2 falls to the shielding grid 4, and the above steps are repeated until the material crushing is completed. The crushing module 8 is closed, and the telescopic end of the second driving member 303 drives the two blocking rotary plates 301 to rotate through the rack rack 304 and the third gear 302. The blocking rotary plates 301 block the shell 2. When the material needs to be crushed again, the above steps are repeated. Example 2

[0030] This embodiment discloses a scrap recovery device for insulation board production, which is a further improvement on the basis of embodiment 1.

[0031] like Figure 3 and Figure 6 As shown, the shaking assembly includes a connecting rod 401, the connecting rod 401 is spline-connected to the sliding frame 3, the connecting rod 401 is rotated and slidably connected with the adjacent rotating shaft 5, the connecting rod 401 is limited and rotated with the adjacent sliding sleeve 6, the connecting rod 401 can drive the sliding sleeve 6 to move synchronously along the rotating shaft 5, the connecting rod 401 is fixedly connected with a clamping block 402, the output end of the first driving member 201 is fixedly connected with a fixing ring 403, the outside of the fixing ring 403 is provided with a sliding groove 404, the clamping block 402 is located in the sliding groove 404 and slides, and the sliding groove 4 04 is a wavy groove, and the two ends of the sliding groove 404 are located on the same side of the fixed ring 403. In this application, the shape of the sliding groove 404 is W-shaped. The clamping block 402 is at one end of the sliding groove 404 in the initial state, and at this moment the two tool holders 7 are in a separated state. When the clamping block 402 is at the other end of the sliding groove 404, the two tool holders 7 are in a fitted state, and the corresponding center angle between the two ends of the sliding groove 404 on the fixed ring 403 is 90°, which is used to make the sliding sleeve 6 drive the tool holder 7 to perform reciprocating linear motion synchronously during the deflection process of the tool holder 7.

[0032] Working principle: When the two tool holders 7 complete the deflection separation of the pre-cutting of the material, the output shaft of the first driving member 201 will drive the first gear 202 to rotate 90°. During this period, the output shaft of the first driving member 201 drives the fixed ring 403 to rotate synchronously, and the fixed ring 403 drives the sliding groove 404 thereon to rotate synchronously. The sliding groove 404 squeezes the adjacent block 402, and the block 402 drives the adjacent connecting rod 401 to perform a linear reciprocating motion. The connecting rod 401 drives the adjacent sliding sleeve 6 to perform a linear reciprocating motion synchronously along the rotating shaft 5, and the sliding sleeve 6 drives the tool holder 7 to move synchronously, so that the two tool holders 7 perform a linear reciprocating motion at the same time during the 90° deflection, so that the tool holder 7 shakes in multiple directions, so that the material hooked thereon is separated from the tool holder 7, and falls downward through the shielding grid 4 to be crushed by the crushing module 8. When the pre-cutting of the material is completed again, the above steps are repeated. Example 3

[0033] This embodiment discloses a scrap recovery device for insulation board production, which is a further improvement on the basis of embodiment 2.

[0034] like Figure 7 and Figure 8 As shown, the outside of the shell 2 is fixedly connected with several connecting blocks, and the shielding grid 4 is slidably connected to the several connecting blocks outside the shell 2. Several first elastic members 501 are provided between the shielding grid 4 and the shell 2. The first elastic member 501 is a spring for pushing the shielding grid 4 to reset. Any connecting block outside the shell 2 is slidably connected to the limit rod 502. The lower part of the limit rod 502 has an inclined surface. A second elastic member 503 is provided between the limit rod 502 and the shell 2. The second elastic member 503 is a spring for pushing the limit rod 502 to reset. The shielding grid 4 is fixedly connected to the limit block 504. The limit block 504 is a frustum-shaped block, and the end with a small diameter is located on the lower side. The annular inclined surface of the limit block 504 can drive the limit rod 502 to move by squeezing the inclined surface of the limit rod 502. The limit rod 502 is used to limit the limit block 504. After the limit block 504 bypasses the limit rod 502, the limit rod 502 limits the limit block 504, and the shielding grid 4 cannot be reset upward. The limit rod 502 is fixedly connected to the first push block 505, and the sliding frame 3 is fixedly connected to the second push block 506. The first push block 505 and the second push block 506 are both isosceles trapezoidal blocks, and the waists of the two squeeze each other, so that the first push block 505 drives the limit rod 502 to move, thereby releasing the limit on the limit block 504, so that the first elastic member 501 drives the shielding grid 4 to reset upward, and the second push block 506 is used to squeeze the first push block 505, so that the limit rod 502 slides along the shell 2, and the first push block 505 is always located above the shielding grid 4, and the vertical distance between the two is greater than the width of the knife holder 7, preventing the shielding grid 4 from colliding with the knife holder 7, while leaving space for the debris on the shielding grid 4 to move.

[0035] Working principle: After the two knife holders 7 are spliced ​​together and fit into the shielding grid 4 to pre-cut the material, the sliding frame 3 drives the knife holder 7 to move downward and after the two knife holders 7 are spliced, the sliding frame 3 drives the second push block 506 to squeeze the first push block 505, and the first push block 505 drives the limiting rod 502 to slide along the shell 2, and the second elastic member 503 is compressed. When the second push block 506 bypasses the first push block 505, the second elastic member 503 drives the limiting rod 502 to reset. At this time, the knife holder 7 does not contact the shielding grid 4. When After the two tool holders 7 continue to move downward and contact the shielding grid 4, the two tool holders 7 push the shielding grid 4 to slide downward along the shell 2. At the same time, the first elastic members 501 are compressed, and the shielding grid 4 drives the limit block 504 thereon to move downward synchronously. When the limit block 504 contacts and squeezes the limit rod 502, the limit rod 502 is squeezed and slides along the shell 2. At the same time, the second elastic member 503 is compressed. When the limit block 504 passes the limit rod 502, the second elastic member 503 is reset and pushes the limit block 504 to move downward. The positioning rod 502 is reset synchronously, so that the limiting rod 502 limits the shielding grid 4 through the limiting block 504. When the material pre-cutting is completed, the sliding frame 3 drives the two knife racks 7 to start moving upward, and the two knife racks 7 are separated from the shielding grid 4. At the same time, the sliding frame 3 drives the second push block 506 thereon to move upward synchronously. The first push block 505 contacts and squeezes the second push block 506. The first push block 505 is driven by the squeezing force to move the limiting rod 502. At the same time, the second elastic member 503 is compressed. At this time, the limiting rod 502 is in contact with the second push block 506. When the limit block 504 is touched, the first elastic members 501 drive the shielding grid 4 to reset quickly, so that the shielding grid 4 drives the material thereon to move synchronously, and causes the short strips of material to float and change their own spatial position, and smoothly pass through the shielding grid 4 and be crushed by the crushing module 8. When the second push block 506 is separated from the first push block 505, the second elastic member 503 pushes the limit rod 502 to reset to the initial state synchronously, and then the two tool holders 7 are deflected and separated from each other. When the material needs to be pre-cut again, repeat the above steps.

[0036] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
