Description

Technical Field

[0001] This invention belongs to the field of wood-plastic flooring palletizing devices, specifically a palletizing device for wood-plastic flooring after surface treatment. Background Technology

[0002] Currently, automated clamping and palletizing equipment is widely used to replace manual palletizing for the palletizing of wood-plastic composite flooring after surface treatment. This can significantly reduce the intensity of manual labor, effectively improve the overall efficiency of batch palletizing of wood-plastic composite flooring, and avoid problems such as skewed placement, disordered stacking, and low work efficiency that are prone to occur during manual palletizing. It is suitable for the industrialized and assembly-line production and processing needs of wood-plastic composite flooring, and its stability and work efficiency are far superior to traditional manual operation.

[0003] Existing wood-plastic composite (WPC) flooring palletizing and clamping equipment still has many shortcomings in practical use. Traditional clamping structures rely solely on rigid clamping force from both sides to fix the flooring. Since WPC flooring is a sheet-like lightweight board, excessive clamping force can cause the board to be squeezed and deformed, surface abrasion, and edge damage, affecting the quality of the finished product. On the other hand, reducing the clamping force can easily lead to the board loosening and falling off during the lifting and moving of the equipment, making it unsuitable for high-speed, high-acceleration automated palletizing operations. At the same time, traditional palletizing equipment often uses a direct release method during the board placement and demolding process, which allows the board to fall freely and deviate from its stacking position, easily causing damage to the board and uneven stacking. The palletizing stability and accuracy are poor, failing to balance the protection effect of the board with the requirements of efficient palletizing operations. Overall, its adaptability and practicality are insufficient. Therefore, a palletizing device for WPC flooring after surface treatment is proposed. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] Given the following technical problems in the existing technology: traditional clamping structures rely solely on the rigid clamping force on both sides to fix the floor. Wood-plastic composite flooring is a sheet-like lightweight board. Excessive clamping force will cause the board to be squeezed and deformed, surface worn, and edge and corner damaged, affecting the quality of the finished product. On the other hand, reducing the clamping force will easily cause the board to loosen and fall off during the lifting and moving of the equipment, which cannot be adapted to high-speed, high-acceleration automated palletizing operations.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a stacking device for wood-plastic composite flooring after surface treatment, comprising: The palletizing structure component includes a palletizing frame, a long straight groove, and a double-headed hydraulic cylinder. The long straight groove is located on the lower side of the palletizing frame, and two clamping components are slidably connected within it. These clamping components are symmetrically arranged on the palletizing frame. A double-headed hydraulic cylinder is positioned in the middle of the long straight groove, with each of its two movable ends fixedly connected to one of the clamping components. By employing a symmetrical hydraulically driven clamping structure, the palletizing structure component enables the clamping components on both sides to open and close synchronously, ensuring centered alignment and improving the symmetry and stability of the palletizing clamping.

[0007] The bottom of the clamping component is equipped with a movable clamping assembly. By integrating a movable clamping structure at the bottom of the movable clamping assembly, flexible and adaptable clamping of wood-plastic composite flooring can be achieved, improving the adaptability of the board clamping.

[0008] As a preferred technical solution for a stacking device after surface treatment of wood-plastic composite flooring, the clamping component includes a sliding seat and a clamping frame. The sliding seat is slidably connected within a long straight groove, and the clamping frame is located at the bottom end of the sliding seat. The middle of the upper side of the clamping frame is fixedly connected to the lower side of the sliding seat, and the width of the clamping frame is more than twice that of the sliding seat. Through the wide structural design of the clamping frame, the clamping contact area with the board is increased, the clamping pressure is distributed, and local stress concentration is avoided to prevent damage to the board.

[0009] As a preferred technical solution for a palletizing device after surface treatment of wood-plastic composite flooring, the movable clamping assembly includes a movable clamping seat and a clamping plate. Two retraction grooves are symmetrically formed on the clamping frame, and the movable clamping seat is movably inserted into each groove. The retraction grooves are located at both ends of the clamping frame, and a clamping plate is provided at one end of each movable clamping seat. The telescopic movable clamping structure of the movable clamping assembly adapts to the clamping needs of different specifications of wood-plastic composite flooring, improving the versatility of the device.

[0010] As a preferred technical solution for a stacking device after surface treatment of wood-plastic composite flooring, the end of the movable clamping seat away from the clamping plate is connected to the inner wall of the magnetic iron sheet by several compression springs. Through the elastic compression structure of the movable clamping seat and the compression springs, flexible clamping and buffering are achieved, effectively cushioning the clamping impact and preventing damage to the board from hard compression.

[0011] As a preferred technical solution for a stacking device after surface treatment of wood-plastic composite flooring, two sets of constraint structures are symmetrically formed on the two opposite vertical surfaces of the long straight groove. Each constraint structure consists of several parallel limiting grooves. Several mounting platforms are provided on both sides of the sliding seat, and these platforms correspond to and slide with the respective limiting grooves. Through the limiting sliding engagement structure between the limiting grooves and the mounting platforms, the sliding trajectory of the clamping components is restricted, preventing clamping deviation and jamming, and ensuring smooth and precise opening and closing actions.

[0012] As a preferred technical solution for a palletizing device after surface treatment of wood-plastic composite flooring, the top of the palletizing frame is equipped with a connector, which includes a connecting platform. The connecting platform consists of a base plate and connecting bolts. The connecting base plate is located on the upper side of the palletizing frame, and connecting bolts are installed on the connecting base plate. Through the bolted connection structure of the connecting platform, a stable assembly and disassembly connection between the device and the robotic arm is achieved, which is convenient to install and has high connection strength.

[0013] As a preferred technical solution for a stacking device after surface treatment of wood-plastic composite flooring, several friction strips are fixedly connected at intervals on the clamping plate, and the friction strips are vertically arranged. The vertically arranged friction strips on the clamping plate increase the friction of the clamping contact surface, prevent the boards from slipping or loosening during transportation, and improve the clamping firmness.

[0014] As a preferred technical solution for a stacking device after surface treatment of wood-plastic composite flooring, the clamping frame is equipped with two U-shaped platforms, which match the magnetic accumulators and movably abut against one side of the friction strip. The U-shaped platform limiting abutment structure restricts the range of motion of the friction strip and the movable clamping structure, ensuring orderly structural operation and preventing misalignment.

[0015] As a preferred technical solution for a stacking device after surface treatment of wood-plastic composite flooring, the clamping component is equipped with a lifting component, which includes a lifting frame, an L-shaped frame, and a lifting plate. A square groove is formed in the center of the bottom of the sliding seat, and the L-shaped frame is movably inserted into the square groove. A lifting plate is located at the bottom end of the L-shaped frame, and a shovel-shaped structure is provided at the end of the lifting plate away from the L-shaped frame. The shovel-shaped structure is a triangular prism structure. The combination of the retractable lifting plate and the shovel-shaped structure provides auxiliary support for the bottom of the flooring, facilitates alignment and support of the flooring, and prevents the flooring from falling and deforming.

[0016] As a preferred technical solution for a stacking device after surface treatment of wood-plastic flooring, the clamping frame is equipped with several gas springs, the movable ends of which are fixedly connected to the side of the L-shaped frame. Through the elastic drive structure of the gas springs, the automatic ejection and resetting of the lifting frame are achieved, ensuring the automated operation of the structure.

[0017] The beneficial effects of the wood-plastic composite flooring surface treatment palletizing device of the present invention are as follows: By setting a composite fixing structure that combines clamping and bottom support, flexible clamping and fixing of sheet wood-plastic composite flooring is achieved, effectively reducing the deformation and surface damage caused by simple lateral extrusion force. At the same time, the bottom support structure supports the weight of the board, which can be adapted to high-speed lifting operation of the equipment and improve the efficiency of palletizing operation. By setting a linkage locking and elastic release structure, the automatic storage and pop-out switching of the support structure is realized, which can be adapted to the entire process of board clamping, transfer and placement. By setting a translational slow-release rolling demolding structure, the slow-release demolding of the board is realized when the board is placed, avoiding the board from falling and bumping directly, ensuring that the board is stacked flat and accurately positioned, which greatly improves the stability of wood-plastic composite flooring palletizing operation and the yield of finished products. By using a magnetic resetting and elastic storage structure, the automatic resetting and locking of the device structure is realized, ensuring the stability of the equipment's cyclic operation and continuously adapting to the batch palletizing processing needs of the production line.

In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0024] like Figures 1-9 As shown, the present invention proposes a stacking device for wood-plastic composite flooring after surface treatment, comprising: The palletizing structure assembly 100 includes a palletizing frame 101, a long straight groove 102, and a double-headed hydraulic cylinder 103. The long straight groove 102 is located on the lower side of the palletizing frame 101, and two clamping members are slidably connected within it. These clamping members are symmetrically arranged on the palletizing frame 101. The double-headed hydraulic cylinder 103 is located in the middle of the long straight groove 102, and its two movable ends are fixedly connected to one of the clamping members. By employing a symmetrical hydraulically driven clamping structure, the palletizing structure assembly 100 enables the clamping members on both sides to open and close synchronously, ensuring centered alignment and improving the symmetry and stability of the palletizing clamping.

[0025] The bottom of the clamping component is provided with a movable clamping assembly 200. By integrating a movable clamping structure at the bottom of the movable clamping assembly 200, flexible adaptation and clamping of wood-plastic flooring can be achieved, improving the adaptability of the board clamping.

[0026] The clamping component includes a sliding seat 104 and a clamping frame 105. The sliding seat 104 is slidably connected within a long straight groove 102. The clamping frame 105 is located at the bottom end of the sliding seat 104. The middle of the upper side of the clamping frame 105 is fixedly connected to the lower side of the sliding seat 104. The width of the clamping frame 105 is more than twice that of the sliding seat 104. Through the wide structural design of the clamping frame 105, the clamping contact area with the sheet metal is increased, the clamping pressure is distributed, and local stress concentration is avoided to prevent damage to the sheet metal.

[0027] The movable clamping assembly 200 includes a movable clamping seat 201 and a clamping plate 202. Two retraction grooves 113 are symmetrically formed on the clamping frame 105, and the movable clamping seat 201 is movably inserted into each retraction groove 113. The retraction grooves 113 are located at both ends of the clamping frame 105, and the clamping plate 202 is provided at one end of the movable clamping seat 201. The retractable movable clamping structure of the movable clamping assembly 200 adapts to the clamping needs of different specifications of wood-plastic composite flooring, improving the versatility of the device.

[0028] The end of the movable clamping seat 201 away from the clamping plate 202 is connected to the inner wall of the magnetic iron sheet 109 by several compression springs. Through the elastic compression structure of the movable clamping seat 201 and the compression springs, flexible clamping and buffering are achieved, effectively buffering the clamping impact force and preventing damage to the sheet material by hard compression.

[0029] Two sets of constraint structures are symmetrically formed on the two opposite vertical surfaces of the long straight groove 102. The constraint structure consists of several parallel limiting grooves 107. Several mounting platforms 108 are provided on both sides of the sliding seat 104. The mounting platforms 108 correspond to and are slidably connected with the corresponding limiting grooves 107. Through the limiting sliding engagement structure between the limiting grooves 107 and the mounting platforms 108, the sliding trajectory of the clamping part is restricted, avoiding clamping deviation and jamming, and ensuring smooth and precise opening and closing actions.

[0030] The top of the palletizing rack 101 is equipped with a connector, which includes a connecting platform 106. The connecting platform 106 is composed of a base plate and connecting bolts. The connecting base plate is located on the upper side of the palletizing rack 101, and the connecting bolts are installed on the connecting base plate. Through the bolted connection structure of the connecting platform 106, a stable connection between the device and the robotic arm can be achieved, which is convenient for installation and has high connection strength.

[0031] Several friction strips 203 are fixedly connected at intervals on the clamping plate 202, and the friction strips 203 are vertically arranged. The vertically arranged friction strips 203 on the clamping plate 202 increase the friction of the clamping contact surface, prevent the plate from slipping or loosening during transportation, and improve the clamping firmness.

[0032] Two U-shaped platforms 112 are provided on the upper part of the clamping frame 105. The U-shaped platforms 112 match the magnetic attracting iron sheet 109, and the U-shaped platforms 112 move and abut against one side of the friction strip 203. The U-shaped platform 112 limits the range of motion of the friction strip 203 and the movable clamping structure through the limiting abutment structure, ensuring that the structure runs in a regular manner and avoiding displacement and misalignment.

[0033] The clamping component is equipped with a lifting element, which includes a lifting frame 300. The lifting frame 300 includes an L-shaped frame 301 and a lifting plate 302. A square groove 110 is provided in the middle of the bottom of the sliding seat 104. The L-shaped frame 301 is movably inserted into the square groove 110. The lifting plate 302 is provided at the bottom end of the L-shaped frame 301. The end of the lifting plate 302 away from the L-shaped frame 301 is provided with a shovel-shaped structure, which is a triangular prism structure. The lifting frame 300 can accommodate the retractable lifting plate 302 in combination with the shovel-shaped structure, thereby providing auxiliary support for the bottom of the plate and facilitating the alignment and support of the plate to prevent it from falling and deforming.

[0034] Several gas springs 309 are installed on the clamping frame 105, and the movable ends of the gas springs 309 are fixedly connected to the side of the L-shaped frame 301. Through the elastic drive structure of the gas springs 309, the lifting frame 300 is automatically ejected and reset by accumulating force, ensuring the automated operation of the structure.

[0035] The palletizing rack 101 is connected to the robotic arm via the connecting platform 106.

[0036] The lifting frame 300 also includes a permanent magnet 307. The top of the L-shaped frame 301 extends into the long straight groove 102 and is fixedly connected to the permanent magnet 307. The inner wall of the long straight groove 102 is provided with a magnetic iron sheet 109, which can be magnetically connected to the permanent magnet 307.

[0037] The movable clamping seat 201 and the L-shaped frame 301 are connected by a control component, which includes a control assembly 400. The control assembly 400 includes a movable vertical platform 401, a horizontal frame 402, a vertical locking post 403, and a rolling cylinder 404. The horizontal frame 402 is L-shaped, with one side of the L-shaped structure fixedly connected to the bottom end of the movable vertical platform 401, and the other side of the L-shaped structure fixedly connected to the vertical locking post 403. The clamping frame 105 has a movable groove 111 on its inner side, and the horizontal frame 402 is movably connected within the movable groove 111. The vertical locking post 403 is provided with a vertical locking post 403. The clamping frame 105 has a vertical groove, and the movable vertical platform 401 is movably connected to the inner side of the vertical groove. The inner bottom wall of the vertical groove is connected to the movable vertical platform 401. A compression spring is provided between the bottom ends of 01. A rolling cylinder 404 is rotatably connected to the movable vertical platform 401. An inclined groove 204 is provided on the movable clamping seat 201. The inner top wall of the inclined groove 204 is inclined. The rolling cylinder 404 extends into the inclined groove 204. The inclined surface of the inclined groove 204 movably abuts against the outer periphery of the rolling cylinder 404. The inclined surface of the inclined groove 204 squeezes the rolling cylinder 404, causing the rolling cylinder 404 and the movable vertical platform 401 to move down. The movable vertical platform 401 compresses the compression spring. A connecting plate 304 is provided on each side of the L-shaped frame 301. The connecting plate 304 is located at the end of the L-shaped frame 301 near the lifting plate 302. The vertical locking pin 403 is movably inserted into the connecting plate 304. The movable vertical platform 401 moves away from the connecting plate 304 with the vertical locking pin 403.

[0038] The lifting plate 302 is equipped with a translational slow-release mechanism. Each translational slow-release mechanism includes two connecting plate frames 308, two limiting strips 306, and two rolling wheels 305. The inner wall of the vertical groove 303 is symmetrically provided with limiting strips 306. The outer circumferential surfaces of the two rolling wheels 305 are in frictional connection. The two rolling wheels 305 rotate in opposite directions and can drive each other. The rolling wheels 305 are distributed vertically and are rotatably connected to the connecting plate frames 308. The connecting plate frames 308 are arranged between the rolling wheels 308 and the connecting plate frames 308. On both sides of 5, several vertical grooves 303 are evenly arranged on the lifting plate 302. A translational slow-release mechanism is arranged in the vertical groove 303. When the wood-plastic flooring 500 is released and the clamping frame 105 and the lifting plate 302 are lowered, the bottom end of the translational slow-release mechanism abuts against the stacking tray. As the lifting plate 302 continues to move down, the translational slow-release mechanism moves relative to the lifting plate 302. The translational slow-release mechanism squeezes the wood-plastic flooring 500, causing the wood-plastic flooring 500 to be lifted and leave the lifting plate 302.

[0039] The specific implementation method is as follows: First stage: The control component 400 locks the position of the lifting frame 300, so that the lifting plate 302 is kept inside the square groove 110. The double-headed hydraulic cylinder 103 pulls the two clamping frames 105 closer to each other through the sliding seat 104, thereby gradually clamping the wood-plastic flooring 500. When the friction strip 203 initially contacts the wood-plastic flooring 500, the lifting plate 302 cannot contact the wood-plastic flooring 500 because it is located inside the square groove 110. During this period, because the L-shaped frame 301 is locked, the clamping frame 105 directly pulls the permanent magnet 307 on the L-shaped frame 301 to get rid of the magnetic iron sheet 109. Second stage: The clamping frame 105 continuously clamps the wood-plastic flooring 500 through the movable clamping component 200. The movable clamping seat 201 is squeezed and continuously enters the interior of the return groove 113. The inclined surface of the inclined groove 204 continuously squeezes the rolling cylinder 404 until the vertical locking column 403 disengages from the connecting plate 304, so that the elastic potential energy of the gas spring 309 on the L-shaped frame 301 is released, and the lifting plate 302 reaches the lower side of the wood-plastic flooring 500. The third stage: When it is necessary to start lifting the movable wood-plastic flooring 500, the palletizing frame 101 is pulled and lifted by the robotic arm. The force between the wood-plastic flooring 500 and the movable clamping component 200 is large. The clamping force of the clamping plate 202 on the clamping frame 105 on the wood-plastic flooring 500 can be increased to make the wood-plastic flooring 500 stably clamped. However, the wood-plastic flooring 500 is a sheet structure. Excessive extrusion force will cause the wood-plastic flooring 500 to deform or even damage the contact surface. Therefore, the lifting plate 302 is used to support the bottom of the wood-plastic flooring 500 to prevent the wood-plastic flooring 500 from falling. This allows the wood-plastic flooring 500 to cope with large vertical acceleration and reduces the extrusion force of the movable clamping component 200 on the wood-plastic flooring 500, reducing damage to the wood-plastic flooring 500 and improving the palletizing efficiency of the wood-plastic flooring 500. Fourth stage: When placing the wood-plastic composite flooring 500, control the position of the lifting plate 302 to be above the stacking tray, and control the friction strip 203 to just leave the wood-plastic composite flooring 500, so that the wood-plastic composite flooring 500 is completely supported by the lifting plate 302. Continue to control the lifting plate 302 to move down a certain distance, so that the rolling wheel 305 at the bottom of the translational release mechanism abuts against the stacking tray, and the rolling wheel 305 at the top of the translational release mechanism moves upward out of the vertical groove 303, so that the wood-plastic composite flooring 500 is lifted away from the lifting plate 302. Continue to control the two clamping frames 1 05. After leaving the wood-plastic composite flooring 500, the clamping frame 105 squeezes the L-shaped frame 301 through the lifting plate 302, causing the lifting plate 302 to move away from the wood-plastic composite flooring 500. The two rolling wheels 305 roll against each other, causing the wood-plastic composite flooring 500 to leave the lifting plate 302. The end of the wood-plastic composite flooring 500 slides down through the upper side of the shovel corner structure of the lifting plate 302 to achieve a slow release, instead of directly causing the wood-plastic composite flooring 500 to fall by removing the movable clamping component 200. This allows the wood-plastic composite flooring 500 to be stacked more stably and avoids falling and causing damage. Fourth stage: As the clamping frames 105 continue to move away from each other, the permanent magnet 307 on the L-shaped frame 301 comes into contact with the corresponding magnetic iron piece 109 and is attracted. Since the attraction strength of the magnetic field is proportional to the square of the distance, the attraction force is strongest at this time and is greater than the maximum elastic force of the gas spring 309. Then, the clamping frames 105 are controlled to move closer together, so that the clamping frames 105 and the L-shaped frame 301 move relative to each other, so that the lifting plate 302 is retracted into the square groove 110. The gas spring 309 is stretched and accumulates potential energy. The connecting plate 304 moves to the position corresponding to the vertical locking post 403. The vertical locking post 403 extends into the connecting plate 304, so that the L-shaped frame 301 and the lifting plate 302 are locked.

[0040] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.
