Description

Technical Field

[0001] The present application relates to the technical field of plate manufacturing, and in particular to plate pulling equipment and a plate production line. Background Art

[0002] A plate puller is a device used to pull and convey cooled plates. It is used for pulling and conveying various types of plates and is a critical and essential device for pulling initially shaped plates downstream. The plate puller consists of a belt conveyor and pressure rollers. The pressure rollers press the plates against the belt conveyor, which then transports the plates, providing a pulling and conveying mechanism.

[0003] Extruded foam boards are widely used in the electronics, home appliance, automotive, construction, and packaging industries due to their light weight, large size, and their ability to provide cushioning, sound absorption, shock absorption, heat preservation, and filtration. However, due to the fluctuating expansion ratio during the extrusion foaming commissioning phase or the testing of new materials, the thickness of the board fluctuates greatly, meaning that the thickness of the board is uneven at different points in the conveying direction. In order to maintain the pressing force on the board and ensure the continuity of the traction force, the distance between the pressure roller and the belt conveyor needs to be adjusted as the thickness of the board changes. Current traction equipment manually adjusts the distance between the pressure roller and the belt conveyor, which may directly contact more dangerous mechanical structures and has poor safety. Utility Model Content

[0004] In view of this, the present application provides a plate pulling device and a plate production line to solve or improve the problem that the current pulling device needs to manually adjust the distance between the pressure roller and the belt conveyor, which has poor safety.

[0009] an air pressure sensor disposed on the flexible roller and adapted to detect the air pressure within the cavity;

[0010] A control module is communicatively connected to the air pressure sensor and the mobile device, respectively. The control module is adapted to control the mobile device to drive the flexible roller to move away from the conveying device when it determines that the air pressure in the cavity is higher than a preset air pressure. The control module is also adapted to control the mobile device to drive the flexible roller to move closer to the conveying device when it determines that the air pressure in the cavity is lower than a preset air pressure.

The control module then determines that the air pressure in the cavity is below the preset pressure and controls the moving device to drive the flexible roller downward, moving it closer to the conveyor. This compresses the flexible roller, increasing the pressure in the cavity until it reaches the preset pressure. This ensures that the pressure in the cavity of the flexible roller is always maintained at the preset pressure. This ensures that the pressure of the flexible roller on the sheet material is constant, ensuring stable sheet material traction and conveyance. Manual adjustment is unnecessary, preventing direct contact with the internal mechanical structure and any potential safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0035] The following combination Figure 1 and Figure 2 , describing the embodiments of the present application.

[0036] According to an embodiment of the present application, on the one hand, a plate pulling device is provided, such as Figure 1 As shown, the system comprises: a conveying device 1, a moving device, a flexible roller 3, an air pressure sensor, and a control module 4. The conveying device 1 is mounted on a frame 8, and a sheet material is placed on the conveying device 1 and conveyed forward. The flexible roller 3 is rotatably connected to the moving device. After the moving device is connected to the frame 8, the flexible roller 3 is positioned above the conveying device 1. At this time, the flexible roller 3 is driven downward by the moving device, and the flexible roller 3 moves closer to the conveying device 1, pressing the sheet material against the conveying device 1, increasing the friction between the sheet material and the conveying device 1, and facilitating the conveying device 1 to transport and pull the sheet material. Conversely, the flexible roller 3 is driven upward by the moving device, and the flexible roller 3 moves away from the conveying device 1, reducing the pressure on the sheet material.

[0037] The flexible roller 3 has an interior cavity filled with air. As the flexible roller 3 moves closer to the conveyor 1 and gradually presses the sheet material against the conveyor 1, the cavity within the flexible roller 3 is compressed. As the flexible roller 3 moves away from the conveyor 1 and gradually reduces the pressure on the sheet material, the degree of compression within the cavity within the flexible roller 3 decreases. An air pressure sensor is provided on the flexible roller 3 and is used to detect the air pressure within the cavity. A control module 4 is communicatively connected to the air pressure sensor and the mobile device. The air pressure sensor detects the air pressure within the cavity of the flexible roller 3 in real time and sends a signal to the control module 4, allowing the control module 4 to determine the air pressure within the cavity of the flexible roller 3 in real time.

[0038] During the sheet conveying process, when the sheet becomes thicker, the flexible roller 3 is squeezed, and the pressure within the cavity increases. At this point, the control module 4 determines that the air pressure within the cavity is higher than a preset pressure and controls the movable device to drive the flexible roller 3 upward and away from the conveying device 1, thereby reducing the degree of compression of the cavity within the flexible roller 3 until the air pressure within the cavity drops to the preset pressure. When the sheet becomes thinner, the degree of compression of the cavity within the flexible roller 3 decreases, and the pressure within the cavity decreases. At this point, the control module 4 determines that the air pressure within the cavity is lower than the preset pressure and controls the movable device to drive the flexible roller 3 downward and closer to the conveying device 1. At this point, the flexible roller 3 is squeezed, and the pressure within the cavity increases until the pressure within the cavity increases to the preset pressure.

[0039] With this arrangement, even with sheets of varying thickness, control module 4 controls the movement device in real time, driving flexible roller 3 toward or away from conveyor 1, ensuring that the pressure within the cavity of flexible roller 3 is consistently maintained at a preset pressure. This ensures a constant pressure on the sheet, ensuring stable sheet traction and conveyance. Manual adjustment is unnecessary, preventing direct contact with the internal mechanical structure and potential safety hazards.

[0040] The control module 4 may be a programmable controller, and the flexible roller 3 may be a vacuum-inflated pressing roller.

[0041] In some embodiments, such as Figure 1 and Figure 2 As shown, the moving device includes a mounting block 5, a screw rod 6, and a drive assembly 7. A rotating hole is provided on the mounting block 5, and the rotating shaft 31 of the flexible roller 3 is detachably inserted into the rotating hole, so that the flexible roller 3 can rotate relative to the mounting block 5. A threaded hole is provided on the mounting block 5, and the extension direction of the threaded hole is perpendicular to the extension direction of the rotating hole. The screw rod 6 is passed through the threaded hole to complete the threaded engagement. At this time, rotating the screw rod 6 can drive the flexible roller 3 to rise and fall and move closer to or away from the conveying device 1. The drive assembly 7 is connected to the screw rod 6 so that the drive assembly 7 can drive the screw rod 6 to rotate. The control module 4 is connected to the drive assembly 7 for communication.

[0042] During the sheet conveying process, when the sheet becomes thicker, the flexible roller 3 is squeezed and the pressure within the cavity increases. At this point, the control module 4 determines that the air pressure within the cavity is higher than the preset pressure and controls the drive assembly 7 to rotate the screw 6, thereby driving the flexible roller 3 upward and away from the conveying device 1, causing the compression of the cavity within the flexible roller 3 to decrease until the air pressure within the cavity drops to the preset pressure. When the sheet becomes thinner, the compression of the cavity within the flexible roller 3 decreases, and the pressure within the cavity decreases. At this point, the control module 4 determines that the air pressure within the cavity is lower than the preset pressure and controls the drive assembly 7 to rotate the screw 6, thereby driving the flexible roller 3 downward and closer to the conveying device 1. At this point, the flexible roller 3 is squeezed and the pressure within the cavity increases until the air pressure within the cavity increases to the preset pressure.

[0043] With such arrangement, the flexible roller 3 is driven to move more precisely and stably by the screw rod 6 .

[0044] In a further embodiment, Figure 1 As shown, the drive assembly 7 includes a gearbox 71 and a motor 72. The gearbox 71 can be any type of gearbox, such as a gearbox. The output shaft of the gearbox 71 is connected to the screw 6, and the input shaft of the gearbox 71 is connected to the motor 72, so that the motor 72 can drive the screw 6 to rotate through the gearbox 71. The motor 72 is a servo stepper motor 72, and the control module 4 is communicatively connected to the motor 72. The control module 4 controls the rotation of the motor 72, thereby driving the screw 6 to rotate through the gearbox 71, thereby driving the flexible roller 3 to move toward or away from the conveyor device 1.

[0045] In one embodiment, Figure 1 and Figure 2 As shown, two moving devices are provided, one at each end of flexible roller 3. The first end of flexible roller 3 is rotationally connected to the first moving device, and the second end of flexible roller 3 is rotationally connected to the second moving device. When flexible roller 3 is moved, the two moving devices operate synchronously, driving the roller 3 at its respective ends. The two moving devices jointly support the roller 3, ensuring smoother movement.

[0046] Specifically, both ends of the flexible roller 3 are provided with a rotating shaft 31 , and the rotating shafts 31 at both ends of the flexible roller 3 are rotatably connected to the mounting blocks 5 of the moving devices on both sides.

[0047] In some embodiments, as Figure 1 and Figure 2 As shown, at least two flexible rollers 3 are provided, and all flexible rollers 3 are arranged sequentially along the conveying direction of the conveyor device 1. The number of movable devices provided corresponds to the number of flexible rollers 3. Each flexible roller 3 is connected to a corresponding movable device, and each movable device is used to drive the corresponding flexible roller 3 toward or away from the conveyor device 1.

[0048] With this arrangement, different flexible rollers 3 press the sheet at different locations during sheet conveyance. For sheets with uneven thickness, the corresponding control module 4 controls the corresponding movement device to drive the corresponding flexible roller 3 toward or away from the conveyor device 1 in real time. This not only compresses the sheet at different locations, ensuring more stable sheet conveyance, but also ensures that each flexible roller 3 exerts the same pressure on the sheet.

[0049] In an optional embodiment, if Figure 2As shown, the flexible roller 3 includes a rotating shaft 31 and a flexible roller body 32. The flexible roller body 32 has a cavity formed therein and filled with air. The flexible roller body 32 may be made of rubber, and the rotating shaft 31 is connected to the flexible roller body 32. The rotating shaft 31 is rotatably connected to the mobile device, thereby rotatably connecting the flexible roller body 32 to the mobile device via the rotating shaft 31.

[0050] In a further embodiment, first anti-slip protrusions are provided on the surface of the flexible roller 32. When the flexible roller 32 is pressed against the plate, the first anti-slip protrusions contact the plate, increasing the friction between the flexible roller 32 and the plate, making the pressing effect of the flexible roller 32 on the plate more effective and reliable.

[0051] The first anti-slip protrusion may be in the shape of a diamond with a side length of 2 mm.

[0052] In one embodiment, Figure 1 As shown, the plate pulling device also includes a control panel 2. A control module 4 is mounted on a frame 8. The control panel 2 is communicatively connected to the control module 4. A user can operate the control panel 2 to issue control commands to the control module 4, instructing the control module 4 to execute corresponding control procedures. This facilitates active user control. The control panel 2 can be a keypad or a touch screen display.

[0053] The control module 4 may also be configured to have a preset air pressure by operating the control panel 2 .

[0054] In an optional embodiment, conveying device 1 is a belt conveyor, and second anti-slip projections are provided on the conveyor belt. When the flexible roller 32 presses the sheet material against the belt, the second anti-slip projections contact the sheet material, increasing the friction between the belt and the sheet material, making the conveyor belt's conveying of the sheet material more efficient and reliable. The diameter of the flexible roller 3 is two-fifths the length of the conveyor belt.

[0055] According to an embodiment of the present application, on the other hand, a plate production line is also provided, comprising any of the above plate traction equipment. The effect brought by the plate production line is consistent with that of the plate traction equipment, so it will not be repeated.

[0056] Although the embodiments of the present application are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations shall fall within the scope defined by the present application.
