Description

TECHNICAL FIELD

[0001] The application relates to the technical field of diffusion plates, in particular to a physical foaming diffusion plate preparation device. BACKGROUND

[0002] A diffusion plate is an optical material for uniformly converting point or line light sources into area light sources. The diffusion plate changes the travel route of light by using the refraction, reflection and scattering phenomena of light when the light encounters two media with different refractive indexes during travel, so as to realize sufficient scattering of incident light and produce uniform light distribution.

[0003] The existing patent (publication number: CN213674266U) discloses a cutting device for a diffusion plate, which comprises a first conveying belt, a second conveying belt and a cutting table. The first end of the second conveying belt is connected to the rear of the tail end of the first conveying belt, and the cutting table is located between the tail end of the first conveying belt and the first end of the second conveying belt. The upper surface of the cutting table is provided with a cutting groove. One side of the second conveying belt is fixedly provided with a first air cylinder. The piston rod of the first air cylinder is fixedly connected with a baffle. The baffle is located above the middle of the second conveying belt. The upper surfaces of the first conveying belt and the second conveying belt are fixedly provided with a downward second air cylinder. The lower end of the piston rod of the second air cylinder is fixedly provided with a pressing plate. The upper surface of the cutting table is fixedly provided with a downward third air cylinder. The lower end of the piston rod of the third air cylinder is fixedly provided with a cutting knife driven by a motor. The cutting device for the diffusion plate can automatically cut the diffusion plate, which is very convenient and saves manpower.

[0004] During the conveying process of the diffusion plate, deviation may occur, which may affect the subsequent cutting operation. In addition, it is inconvenient to move the position of the baffle, that is, it is inconvenient to adjust the cutting size of the diffusion plate. The flexibility and practicality are low, and there is room for improvement. Practical new type content

[0005] In view of the deficiencies of the prior art, the application provides a physical foaming diffusion plate preparation device, which has the advantages of being capable of limiting diffusion plates of different sizes, avoiding deviation of the diffusion plate during the conveying and cutting process of the diffusion plate, ensuring the cutting quality and the continuous and smooth progress of the cutting operation, and being capable of adjusting the cutting size according to needs, improving the flexibility and practicality of the device, and solving the problems of the existing diffusion plate cutting device, such as the easy deviation of the diffusion plate during the conveying process of the diffusion plate, the influence on the subsequent cutting operation, the inconvenience of adjusting the cutting size of the diffusion plate, and the low flexibility and practicality.

[0006] To achieve the above objectives, this application provides the following technical solution: a physical foaming diffusion plate preparation device, comprising a frame, a first conveyor belt inside the frame, a second conveyor belt inside the frame, a cutting table between the first and second conveyor belts, the bottom surface of the cutting table being fixedly connected to the upper surface of the frame, a lead screw being rotatably connected inside the frame, two threaded tubes being threadedly connected to the outer circumference of the lead screw, a limit plate being fixedly connected to the outer circumference of each threaded tube, a first cylinder being fixedly connected to the top of the frame, a cutting blade being fixedly connected to the output end of the first cylinder, a movable frame being slidably connected to the outer surface of the frame, two sliding grooves being formed inside the movable frame, two sliding plates being fixedly connected to the outer surface of the frame, the movable frame being slidably connected to the outer surface of the sliding plates through the sliding grooves, a second cylinder being fixedly connected to the top of the movable frame, a baffle being fixedly connected to the output end of the second cylinder, pressure sensors being arranged at equal intervals on the outer surface of the baffle, and two control rods being rotatably connected inside the movable frame, a positioning rod being threadedly connected to the outer circumference of each control rod.

[0007] The above solution addresses the issue that existing diffuser plate cutting devices are prone to diffuser plate misalignment during transport, impacting subsequent cutting operations and hindering adjustment of cut dimensions. This results in lower flexibility and practicality. By rotating the lead screw to move the threaded tube in the opposite direction, the spacing between the limiting plates can be adjusted according to the diffuser plate size. This limits the movement of diffuser plates of different sizes during transport, preventing misalignment and ensuring cutting quality and smooth operation. Furthermore, rotating the control lever to move the positioning rod facilitates the movement and fixation of the moving frame, allowing for easy adjustment of the diffuser plate cut dimensions as needed, thus improving the device's flexibility and practicality.

[0008] Furthermore, the lead screw is a bidirectional threaded rod, and two first limiting rings are fixedly sleeved on the outer circumferential surface of the lead screw. The side of the first limiting rings closest to the frame contacts the outer surface of the frame.

[0009] Through the above scheme, the first limiting ring can restrict the lead screw, prevent the lead screw from sliding and deviating laterally, and improve the stability of the lead screw movement. The lead screw with a bidirectional thread structure can cause the threaded tube to move in the opposite direction, and then adjust the spacing of the limiting plates as needed to complete the limiting operation of diffuser plates of different sizes.

[0010] Furthermore, the frame has two crossbars fixedly connected inside, and the limiting plates are slidably connected to the outer circumferential surface of the crossbars through internal slots.

[0011] Through the above scheme, the threaded pipe is limited, the threaded pipe and the limiting plate are always moved transversely, and the stability of the movement of the limiting plate is improved.

[0012] Further, the upper surface of the cutting table is provided with a cutting groove, and the cutting groove is located directly below the cutting knife.

[0013] Through the above scheme, after the cutting knife moves down to the bottom, the cutting operation on the diffusion plate can be completed under the action of the cutting groove.

[0014] Further, the top end of the rack is fixedly connected with two third cylinders, and the two third cylinders are symmetrically arranged on the two sides of the first cylinder, and the output end of each third cylinder is fixedly connected with a pressing plate.

[0015] Through the above scheme, the third cylinder can drive the pressing plate to move down, and the diffusion plate can be positioned before cutting, so as to ensure the cutting quality of the subsequent diffusion plate.

[0016] Further, the outer circumferential surface of each control rod is fixedly sleeved with a second limiting ring, and the outer circumferential surface of the second limiting ring is rotatably connected with the inner part of the moving frame.

[0017] Through the above scheme, the control rod is limited, so as to avoid sliding deviation of the control rod and improve the stability of the movement of the control rod.

[0018] Further, the outer circumferential surface of each positioning rod is fixedly connected with a limiting block, and the outer surface of the limiting block is slidably connected with the moving frame through the air slot formed in the inner part of the moving frame.

[0019] Through the above scheme, the positioning rod is limited, so as to always move transversely, abut against the outer surface of the sliding plate, and complete the positioning operation on the moving frame under the action of friction, thereby avoiding rotation of the positioning rod with the control rod.

[0020] Further, the outer surface of each sliding plate is provided with equally arranged scale grooves, and the cutting groove is the initial position of the scale groove.

[0021] Through the above scheme, the moving frame can be moved according to the scale groove by the staff, and the cutting length of the diffusion plate can be adjusted.

[0022] Compared with the prior art, the technical scheme of the present application has the following beneficial effects:

[0023] The physical foaming diffusion plate preparation equipment, by rotating the screw rod drives the threaded pipe to move towards the opposite direction, prompting the spacing between the limiting plates can be adjusted according to the size of the diffusion plate, and then the diffusion plate of different sizes is limited during conveying, avoiding the diffusion plate from deviating during conveying, ensuring the cutting quality and the continuous and smooth cutting operation, by rotating the control rod to mobilize the positioning rod to move, it is convenient to move and fix the moving frame, and then it is convenient to adjust the cutting size of the diffusion plate according to the need, improve the flexibility and practicability of the device, solve the problems that the existing diffusion plate cutting device is easy to deviate during conveying the diffusion plate, affects the subsequent cutting operation, and the cutting size of the diffusion plate is not convenient to adjust.

[0044] The working principle of the above embodiments is as follows:

[0045] During the diffusion plate cutting operation, the diffusion plate is placed on the first conveyor belt 2. Rotating the lead screw 5 drives the limiting plates 7 to move in opposite directions via the threaded tube 6. The distance between the two limiting plates 7 is adjusted according to the size of the diffusion plate, restricting the diffusion plate on both sides to prevent displacement during movement. Then, the position of the moving frame 10 is adjusted according to the scale groove on the slide plate 12. The moving frame 10 is moved to the appropriate position according to the required diffusion plate size. After the moving frame 10 has moved, the control lever 16 is rotated sequentially to move the positioning rod 17 forward, causing the positioning rod 17 to press against the slide plate 12, completing the positioning operation of the moving frame 10. Finally, the first conveyor belt 2 and the second conveyor belt 3 can be started. The diffuser plate is conveyed and, after moving to the position of baffle 14, it will press against pressure sensor 15. After pressure sensor 15 detects that the diffuser plate has moved to the position of baffle 14, the first conveyor belt 2 and the second conveyor belt 3 stop running. The third cylinder 21 drives the pressure plate 22 to move down and press it on the diffuser plate, positioning both sides of the diffuser plate cutting area. Then, the first cylinder 8 drives the cutting blade 9 to move down to complete the cutting operation of the diffuser plate. After the cutting operation is completed, the cutting blade 9 and the pressure plate 22 move back, and the second cylinder 13 is started to drive the baffle 14 to move up. The second conveyor belt 3 starts to remove the cut diffuser plate. Then, the baffle 14 moves down to reset, and the first conveyor belt 2 starts to continue the subsequent diffuser plate cutting operation.
