Description

Technical Field

[0001] This utility model belongs to the field of plywood cold pressing technology, and in particular relates to an environmentally friendly plywood cold pressing device. Background Technology

[0002] Environmentally friendly cold-pressed plywood is a green manufacturing technology that uses formaldehyde-free or low-formaldehyde environmentally friendly adhesives (such as soybean protein glue, MDI glue, etc.) to laminate veneers through a cold-pressing process (applying pressure at room temperature or lower). Its core advantages lie in the elimination of high-temperature hot pressing, resulting in low energy consumption and rapid curing. Simultaneously, it reduces the release of harmful substances such as formaldehyde from the adhesive source, meeting E0 grade or even formaldehyde-free standards. This ensures the strength and stability of the plywood while significantly reducing its impact on the environment and human health, making it widely used in furniture, interior decoration, and other fields with high environmental protection requirements.

[0003] For example, Chinese patent CN211762183U discloses an environmentally friendly plywood cold pressing device, including a cold pressing device body. The cold pressing device body mainly consists of a base, a top plate, a compression cylinder, a pressure plate, a housing, a transmission device, and four support columns. The base is fixed to the bottom of the housing. The support columns pass through the pressure plate and are slidably connected to it, and are fixed between the top plate and the base. Four casters and four support mechanisms are fixedly connected to the bottom of the housing. Openings are provided at both ends of the housing, and sealing doors are rotatably connected to the top of each of the two openings. Both sealing doors are bolted to the housing, and a positioning mechanism is provided between the two sealing doors and the housing. This utility model has a reasonable structure. The housing not only provides dust protection for the cold pressing device body but also does not affect its participation in the production line. It also facilitates the movement of the cold pressing device body, improving installation efficiency.

[0004] The above-mentioned patent has the following problems: In actual use, it does not have the function of limiting and fixing both sides of the plywood. During the cold pressing operation, the layers of the plywood blank are prone to sliding and displacement, or the glue strength is insufficient, resulting in delamination, which is not conducive to the use of workers. In view of this, we propose an environmentally friendly plywood cold pressing device. Utility Model Content

[0005] The purpose of this invention is to provide an environmentally friendly plywood cold pressing device to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides an environmentally friendly plywood cold pressing device, comprising: A fixed frame, which is "n" shaped, has a hydraulic push rod fixedly installed on the top of the fixed frame, the bottom of the hydraulic push rod extending into the interior of the fixed frame, and a cold pressing plate fixedly connected to the output end of the hydraulic push rod; Six support columns are fixedly connected to the bottom of the inner wall of the fixed frame. The top of the six support columns is fixedly connected to the same housing. The top of the housing is provided with two symmetrically distributed clamps. A motor is provided on one side of the housing. A movable component is disposed inside the housing and is used to move the two clamping plates simultaneously.

[0007] In this technical solution, after the device is started, the fixed frame serves as a basic support structure to maintain stability. The top hydraulic push rod pushes the cold pressing plate downward to apply pressure to the plywood placed inside the housing. The six support columns at the bottom of the inner wall of the fixed frame support and position the housing. The two clamping plates at the top of the housing are symmetrically distributed to clamp the plywood from both sides. The motor is fixed on one side of the housing through a support plate. The motor provides power to the moving components and drives the clamping plates to adjust the spacing to accommodate plywood of different sizes.

[0008] By starting the motor, the bidirectional screw rotates, and the two threaded sleeves slide. The first and second rotating frames are linked by a connecting rod, causing the first slider at the bottom to slide on the inner wall of the housing. At the same time, the second slider at the top slides synchronously in the through groove, thereby controlling the horizontal movement of the clamping plate to complete the clamping or releasing action. The telescopic rods in the multi-stage telescopic sleeves on the L-shaped connecting plates on both sides of the housing connect the clamping plate, ensuring that the clamping plate moves smoothly and maintains continuous clamping force during cold pressing to prevent the plywood from shifting. With the above structure, plywood can be cold-pressed. During cold pressing, this device can limit and fix the two sides of the plywood, avoiding the slippage and displacement between the layers of the board during cold pressing, or the phenomenon of delamination due to insufficient bonding strength, thus facilitating the use of the operator.

[0009] In the above technical solution, a support plate is fixedly connected to one side of the housing, and the motor is fixedly mounted on the support plate.

[0010] In this technical solution, the support plate ensures that the motor will not idle during operation.

[0011] In the above technical solution, a bidirectional screw is rotatably installed inside the housing. One end of the bidirectional screw is fixedly connected to the output end of the motor. The two helical directions of the bidirectional screw are opposite. The external thread of the bidirectional screw is connected to two symmetrically distributed threaded sleeves. The bottom of the two threaded sleeves is slidably installed on the bottom of the inner wall of the housing.

[0012] In this technical solution, by starting the motor, the output end of the motor drives the bidirectional screw to rotate. Because the two ends of the bidirectional screw have opposite helical directions, the two external threaded sleeves slide along the bottom of the inner wall of the housing to the sides or the middle respectively.

[0013] In the above technical solution, further, two symmetrically distributed first sliders are slidably installed on the bottom of the inner wall of the housing, and two symmetrically distributed through slots are opened on the top of the housing. A second slider is slidably installed inside each of the two through slots, and the two second sliders are fixedly connected to the two clamping plates respectively.

[0014] In this technical solution, by sliding the first slider on the bottom of the inner wall of the housing, the second rotating frame can be made more stable when moving.

[0015] In the above technical solution, the moving component further includes four first rotating frames, which are respectively fixedly connected to both sides of the two threaded sleeves. Two symmetrically distributed second rotating frames are fixedly connected to the top of each of the two first sliders. The tops of the four second rotating frames are respectively fixedly connected to the bottoms of the two second sliders. The first rotating frames and the second rotating frames are fixedly connected by the same connecting rod.

[0016] In this technical solution, the first rotating frame and the second rotating frame on both sides of the threaded sleeve are linked by a connecting rod to drive the first slider at the bottom to slide at the bottom of the inner wall of the housing, while the second slider at the top slides synchronously in the through groove, thereby controlling the horizontal movement of the clamping plate to complete the clamping or releasing action.

[0017] In the above technical solution, further, both sides of the shell are fixedly connected to connecting plates, both connecting plates are "L" shaped, and two symmetrically distributed multi-stage telescopic sleeves are fixedly installed on one side of each of the two connecting plates. Telescopic rods are slidably installed inside the four multi-stage telescopic sleeves, and the other ends of the four telescopic rods are respectively fixedly connected to one side of the two clamping plates.

[0018] In this technical solution, the telescopic rods inside the multi-stage telescopic sleeves on the L-shaped connecting plates on both sides of the housing are connected to the clamping plates, ensuring that the clamping plates move smoothly and can maintain continuous clamping force during the cold pressing process to prevent the plywood from shifting.

[0019] Furthermore, in the above technical solution, both connecting plates are L-shaped.

[0020] In this technical solution, the "L"-shaped connecting plate makes the connecting plate more compatible with the device.

[0021] The beneficial effects of this utility model are: 1. After the device is started, the fixed frame serves as the basic support structure to maintain stability. The top hydraulic push rod pushes the cold pressing plate downward to apply pressure to the plywood placed inside the housing. The six support columns at the bottom of the inner wall of the fixed frame support and position the housing. The two clamping plates at the top of the housing are symmetrically distributed to clamp the plywood from both sides. The motor is fixed on one side of the housing through the support plate. The motor provides power to the moving components and drives the clamping plates to adjust the spacing to accommodate plywood of different sizes.

[0022] 2. By starting the motor, the bidirectional screw rotates, and the two threaded sleeves slide. The first rotating frame and the second rotating frame are linked by a connecting rod, causing the first slider at the bottom to slide on the bottom of the inner wall of the housing. At the same time, the second slider at the top slides synchronously in the through groove, thereby controlling the horizontal movement of the clamping plate to complete the clamping or releasing action. The telescopic rods in the multi-stage telescopic sleeves on the L-shaped connecting plates on both sides of the housing connect the clamping plate, ensuring that the clamping plate moves smoothly and maintains continuous clamping force during cold pressing to prevent the plywood from shifting. With the above structure, the plywood can be cold pressed. During the cold pressing operation, this device can limit and fix the two sides of the plywood, avoiding the phenomenon of easy sliding and displacement between the layers of the board during cold pressing, or insufficient bonding strength leading to delamination, thus facilitating the use of the operator.

These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0027] Example 1: This example provides an environmentally friendly plywood cold pressing device, comprising: The fixed frame 1 is "n" shaped. A hydraulic push rod 18 is fixedly installed on the top of the fixed frame 1. The bottom of the hydraulic push rod 18 extends into the interior of the fixed frame 1. A cold pressure plate 19 is fixedly connected to the output end of the hydraulic push rod 18. Six support columns 2 are fixedly connected to the bottom of the inner wall of the fixed frame 1. The top of the six support columns 2 is fixedly connected to the same housing 3. The top of the housing 3 is provided with two symmetrically distributed clamping plates 15. A motor 5 is provided on one side of the housing 3. A movable component is located inside the housing 3 and is used to move the two clamping plates 15 simultaneously.

[0028] After the device is started, the fixed frame 1 serves as a basic support structure to maintain stability. The top hydraulic push rod 18 pushes the cold pressing plate 19 downward to apply pressure to the plywood placed inside the housing 3. The six support columns 2 at the bottom of the inner wall of the fixed frame 1 support the housing 3 and position it. The two clamping plates 15 at the top of the housing 3 are symmetrically distributed to clamp the plywood from both sides. The motor 5 is fixed on one side of the housing 3 through the support plate 4. The motor 5 provides power to the moving components and drives the clamping plates 15 to adjust the spacing to accommodate plywood of different sizes.

[0029] By starting the motor 5, the bidirectional screw 6 is driven to rotate, and the two threaded sleeves 7 slide. The first rotating frame 9 and the second rotating frame 10 are linked by the connecting rod 11 to drive the first slider 8 at the bottom to slide on the bottom of the inner wall of the housing 3. At the same time, the second slider 12 at the top slides synchronously in the through groove 13, thereby controlling the horizontal movement of the clamping plate 15 to complete the clamping or releasing action. The telescopic rod 17 in the multi-stage telescopic sleeve 16 on the L-shaped connecting plate 14 on both sides of the housing 3 connects the clamping plate 15, ensuring that the clamping plate 15 moves smoothly and can maintain a continuous clamping force during the cold pressing process to prevent the plywood from shifting. With the above structure, the plywood can be cold pressed. During the cold pressing operation, this device can limit and fix the two sides of the plywood, avoiding the phenomenon that the layers of the board are prone to sliding and shifting or that the bonding strength is insufficient and delamination occurs during the cold pressing, thus making it convenient for workers to use.

In addition to the technical solutions of the above examples, it also has the following technical features: a support plate 4 is fixedly connected to one side of the housing 3, and a motor 5 is fixedly installed on the support plate 4.

[0031] The support plate 4 ensures that the motor 5 will not idle during operation.

[0032] Example 3: This example provides an environmentally friendly plywood cold pressing device. In addition to the technical solutions of the above examples, it also has the following technical features: a bidirectional screw 6 is rotatably installed inside the housing 3. One end of the bidirectional screw 6 is fixedly connected to the output end of the motor 5. The two helical directions of the bidirectional screw 6 are opposite. The external thread of the bidirectional screw 6 is connected to two symmetrically distributed threaded sleeves 7. The bottom of the two threaded sleeves 7 is slidably installed on the bottom of the inner wall of the housing 3.

[0033] Among them, by starting the motor 5, the output end of the motor 5 drives the bidirectional screw 6 to rotate. Because the two ends of the bidirectional screw 6 have opposite spiral directions, the two threaded sleeves 7 on the outside slide along the bottom of the inner wall of the housing 3 to the sides or the middle respectively.

[0034] Example 4: This example provides an environmentally friendly plywood cold pressing device. In addition to the technical solutions of the above examples, it also has the following technical features: two symmetrically distributed first sliders 8 are slidably installed on the bottom of the inner wall of the housing 3, and two symmetrically distributed through slots 13 are opened on the top of the housing 3. A second slider 12 is slidably installed inside each of the two through slots 13, and the two second sliders 12 are fixedly connected to the two clamping plates 15 respectively.

[0035] The second rotating frame 10 is made more stable when it moves by sliding the first slider 8 on the bottom of the inner wall of the housing 3.

[0036] Example 5: This example provides an environmentally friendly plywood cold pressing device. In addition to the technical solutions of the above examples, it also has the following technical features: the moving component includes four first rotating frames 9, which are respectively fixedly connected to both sides of two threaded sleeves 7. The tops of the two first sliders 8 are each fixedly connected to two symmetrically distributed second rotating frames 10. The tops of the four second rotating frames 10 are respectively fixedly connected to the bottoms of the two second sliders 12. The first rotating frames 9 and the second rotating frames 10 are fixedly connected to the same connecting rod 11.

[0037] Among them, the first rotating frame 9 and the second rotating frame 10 on both sides of the threaded sleeve 7 are linked by the connecting rod 11 to drive the first slider 8 at the bottom to slide at the bottom of the inner wall of the housing 3, while the second slider 12 at the top slides synchronously in the through groove 13, thereby controlling the horizontal movement of the clamping plate 15 to complete the clamping or releasing action.

[0038] Example 6: This example provides an environmentally friendly plywood cold pressing device. In addition to the technical solutions of the above examples, it also has the following technical features: connecting plates 14 are fixedly connected to both sides of the shell 3. Both connecting plates 14 are "L" shaped. Two symmetrically distributed multi-stage telescopic sleeves 16 are fixedly installed on one side of each of the two connecting plates 14. Telescopic rods 17 are slidably installed inside each of the four multi-stage telescopic sleeves 16. The other ends of the four telescopic rods 17 are respectively fixedly connected to one side of the two clamping plates 15.

[0039] Among them, the telescopic rod 17 inside the multi-stage telescopic sleeve 16 on the L-shaped connecting plates 14 on both sides of the housing 3 is connected to the clamping plate 15, which ensures that the clamping plate 15 moves smoothly and can maintain continuous clamping force during the cold pressing process to prevent the plywood from shifting.

[0040] Example 7: This example provides an environmentally friendly plywood cold pressing device. In addition to the technical solutions of the above examples, it also has the following technical features: both connecting plates 14 are "L" shaped.

[0041] The L-shaped connecting plate 14 makes it more compatible with this device.

[0042] Working principle: After the device is started, the fixed frame 1 serves as the basic support structure to maintain stability. The top hydraulic push rod 18 pushes the cold pressing plate 19 downward to apply pressure to the plywood placed in the housing 3. The six support columns 2 at the bottom of the inner wall of the fixed frame 1 support the housing 3 and position it. The two clamping plates 15 at the top of the housing 3 are symmetrically distributed to clamp the plywood from both sides. The motor 5 is fixed on one side of the housing 3 through the support plate 4. The motor 5 provides power to the moving components and drives the clamping plates 15 to adjust the spacing to accommodate plywood of different sizes.

[0043] By starting the motor 5, the output end of the motor 5 drives the bidirectional screw 6 to rotate. Because the two ends of the bidirectional screw 6 have opposite spiral directions, the two threaded sleeves 7 on the outside slide along the bottom of the inner wall of the housing 3 to the sides or the middle respectively. The first rotating frame 9 and the second rotating frame 10 on both sides of the threaded sleeve 7 are linked by the connecting rod 11 to drive the first slider 8 at the bottom to slide at the bottom of the inner wall of the housing 3. At the same time, the second slider 12 at the top slides synchronously in the through groove 13, thereby controlling the horizontal movement of the clamping plate 15 to complete the clamping or releasing action. The telescopic rod 17 in the multi-stage telescopic sleeve 16 on the L-shaped connecting plate 14 on both sides of the housing 3 connects to the clamping plate 15, ensuring that the clamping plate 15 moves smoothly and can maintain a continuous clamping force during the cold pressing process to prevent the plywood from shifting. With the above structure, the plywood can be cold pressed. During the cold pressing operation, this device can limit and fix the two sides of the plywood, avoiding the phenomenon that the layers of the board are prone to sliding and shifting or that the bonding strength is insufficient and delamination occurs during the cold pressing, thus facilitating the use of the staff.
