Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a fixed-length cutting platform for producing acrylic plates. Background Art

[0002] Acrylic, commonly known as specially treated plexiglass, is a special material that is light, corrosion-resistant, easy to shape and inexpensive. It is widely used in many fields, such as instrument parts, car lights, optical lenses, transparent pipes, etc.

[0003] At present, when making corresponding products, acrylic sheets need to be cut to length, and traditional cutting equipment generally only includes a cutting table and a cutting tool, which cannot complete the control of the cutting length of the sheet, so it is inconvenient. In the prior art, there are also devices that can achieve fixed-length cutting. For example, the utility model patent with publication number CN219599717U proposes a plastic sheet fixed-length cutting device, which includes an operating table, an adjustment plate, a measuring frame, a telescopic rod and a sliding plate. In the actual application process, the patented technical solution limits the position of the sheet by the position of the adjustment plate, thereby achieving fixed-length cutting. After cutting, the sliding plate pushes the cut sheet into the blanking plate, and so on.

[0004] However, although the equipment can complete the fixed-length cutting of the plate, the position of the adjustment plate remains unchanged after being determined. Therefore, when the sliding plate is used to push the plate to unload, friction will occur between the plate and the adjustment plate, which may affect the quality of the finished plate. If the adjustment plate is controlled to retreat after the cutting is completed, although friction between the plate and the adjustment plate can be avoided, the operation process is more troublesome and is not conducive to improving work efficiency. To this end, we proposed a fixed-length cutting platform for acrylic plate production to solve the above drawbacks. Utility Model Content

[0025] In addition, a plate limiting mechanism 300 is provided on the top surface of the cutting table 100 and on one side of the cutting opening 101. Specifically, the plate limiting mechanism 300 includes a fixed plate 301 and a movable plate 302.

The bottom of the movable plate 302 extends into the sliding opening 116, and the movable plate 302 is penetrated by the light rod 117 and slidably cooperates with the light rod 117; therefore, the movable plate 302 can slide along the length direction of the light rod 117, thereby approaching or moving away from the fixed plate 302.

[0026] Furthermore, an adjustment opening 118 is provided on the top surface of the cutting table 100, and the bottom of the movable plate 302 extends into the adjustment opening 118.

[0027] It is worth mentioning that a step plate 119 is provided on the top surface of the cutting table 100 and between the fixed plate 301 and the movable plate 302. In this embodiment, the number of the step plates 119 is four. Figure 1 As shown, during the specific operation, the plate can be placed on the step plate 119, and one side of the plate is fitted with the fixed plate 301, and then the movable plate 302 is used to approach the fixed plate 301 and press the plate, so as to fix the position of the plate and improve the stability during cutting.

[0028] A movable opening 105 is provided on the top surface of the cutting table 100 and on the opposite side of the plate limiting mechanism 300.

The guide rods 110 penetrate the lifting plate 109 and slide with it, and a return spring 111 is also sleeved on the outer side of the guide rod 110. The upper and lower ends of the return spring 111 are respectively fixedly connected to the bottom surface of the lifting plate 109 and the inner bottom surface of the mounting frame 102. In the natural state, the return spring 111 is in a compressed state, and the top surface of the lifting plate 109 fits with the bottom surface of the displacement plate 104. A driving rod 112 is provided at one end of the lifting plate 109, and a through hole is formed at the bottom of the blocking plate 108 for the driving rod 112 to pass through, and the driving rod 112 is movably inserted in the through hole; a trapezoidal block 113 is fixedly provided at one end of the top surface of the lifting plate 109, and when the bottom surface of the displacement plate 104 is in contact with the top surface of the trapezoidal block 113, the top of the blocking plate 108 is lower than the upper surface of the cutting table 100; specifically, when the displacement plate 104 and the top surface of the lifting plate 109 are in contact, the top of the blocking plate 108 is higher than the top surface of the step plate 119, so the blocking plate 108 can limit the plate, and when the displacement plate 104 and the top surface of the trapezoidal block 113 are in contact, the lifting plate 109 can carry the blocking plate 108 down synchronously, so that the top of the blocking plate 108 is lower than the upper surface of the cutting table 100, and at this time the blocking plate 108 will not block the plate from moving forward.

[0030] In addition, installation openings 114 are provided on the top surface of the cutting table 100 and on the front and rear sides of the movable opening 105.

The plate conveying mechanism 115 can adopt a belt conveyor, and the upper surface of the plate conveying mechanism 115 is higher than the top surface of the cutting table 100 and lower than the top surface of the step plate 119, so that the cut plate can automatically fall on the plate conveying mechanism 115.

[0031] In summary, in actual use of this embodiment, the displacement block 107 is first controlled to move to a proper position by the propulsion cylinder 106, and then the plate to be cut is placed on the step plate 119, so that one side of the plate is in contact with the fixed plate 301, and the front end of the plate is in contact with the blocking plate 108, and then the movable plate 302 is moved close to the fixed plate 301 to clamp and fix the plate; after the plate is fixed, the cutting mechanism 200 is turned on, and then the linear slide 103 is used to control the cutting mechanism 200 to move along the length direction of the cutting opening 101, so as to cut the plate; it should be noted that when the cutting mechanism 200 completes the cutting action and moves to the upper position of the trapezoidal block 113, the lifting plate 109 and the blocking plate 108 are synchronously lowered, and at this time, the top of the blocking plate 108 is lower than the lower surface of the plate. After the plate is cut, the cut plate automatically falls on the plate conveying mechanism 115 and is output to one side of the cutting table 100. Finally, the linear slide 103 controls the cutting mechanism 200 to move to the original position, waiting for the next cutting task to be performed.
