Description

Technical Field

[0001] This utility model belongs to the field of plastic sheet processing technology, specifically a plastic sheet processing device. Background Technology

[0002] Plastic sheets are sheet-like materials with a certain thickness and size, made primarily of synthetic resin with the addition of fillers, plasticizers, stabilizers, colorants, and other auxiliary materials, through processes such as pressing, extrusion, and molding. There are many types, the most common being PVC sheets, PP sheets, PE sheets, PC sheets, and acrylic (PMMA) sheets. Plastic sheets have advantages such as being lightweight, corrosion-resistant, having good electrical insulation, and being easy to process and mold. They are widely used in construction, advertising, packaging, chemical, electronics, and medical fields, for example, in the production of billboards, interior decoration materials, chemical containers, machine guards, and light box panels. However, some plastic sheets require surface painting and engraving treatments according to specific needs. These processes require placing the sheets on a platform, but traditional platforms have fixed structures that can only hold plastic sheets of a fixed size. When larger sheets are placed on them, the flatness of the sheets cannot be guaranteed, affecting the painting and engraving operations. Therefore, improvements are needed to address these issues. Utility Model Content

[0003] To achieve the above objectives, this utility model provides the following technical solution: a plastic sheet processing device, including a base, an n-shaped platform fixedly installed on the top of the base, an extension plate flush with the top of the n-shaped platform at both ends, two pairs of sliding grooves symmetrically opened inside the n-shaped platform, a movable and adjustable support slide plate installed between each pair of sliding grooves, the two support slide plates being located below the two extension plates respectively, and an adjuster installed between adjacent support slide plates and extension plates, and a dual-output shaft motor connected to the two support slide plates installed in the middle of the top of the base.

[0004] Preferably, each of the grooves consists of a shallow groove and a deep groove, with the deep groove located inside the shallow groove. The support slide plate is slidably installed between two opposite shallow grooves. A slider is fixedly installed at one end of the support slide plate, and both ends of the slider are slidably installed inside two opposite deep grooves. A threaded shaft is threadedly connected between the middle of the support slide plate and the slider. The opposite ends of the two threaded shafts are fixedly connected to the two output ends of the dual-output shaft motor.

[0005] Preferably, the adjuster includes two pairs of first connecting blocks fixedly installed on the top of the support slide plate. An adjusting shaft is rotatably connected between the upper parts of each pair of first connecting blocks. A first rotating arm is fixedly connected to both ends of each adjusting shaft. A second rotating arm is rotatably connected to one side of each first connecting block. A base plate is fixedly connected to the bottom of each of the two extension plates. Two pairs of second connecting blocks are fixedly connected to the bottom of each of the two base plates. The tops of adjacent first rotating arms and second rotating arms are rotatably connected to the same second connecting block.

[0006] Preferably, both ends of one of the adjusting shafts on the two supporting slides are fixedly mounted with transmission gears, the middle of the two adjusting shafts on the supporting slides are fixedly mounted with sprockets, a chain is installed between the sprockets on the supporting slides, and toothed plates that cooperate with the four transmission gears are fixedly mounted at both ends of the inner sides of the n-shaped base.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: This plastic sheet processing device has a two-way expandable table structure, which can adjust the placement area of ​​the platform according to the usage requirements, thereby effectively improving the stability of plastic sheet painting and carving processing. When the two extension plates need to be retracted and moved into the n-shaped base, the dual-output shaft motor is first started to rotate the two threaded shafts. The rotation of the two threaded shafts causes the two support slide plates and the sliders on the support slide plates to slide relative to each other inside the shallow and deep grooves. The relative movement of the two support slide plates drives the transmission gears on them to move, causing the transmission gears to roll on the gear plate. The rolling movement of the transmission gears drives one of the adjustment shafts on the support slide plate to rotate. The rotation of one adjustment shaft drives the other adjustment shaft on the support slide plate to rotate through the sprocket and chain. This causes the two adjustment shafts on the support slide plate to rotate synchronously, driving the four first rotating arms on the support slide plate to rotate downwards. At the same time, through the four rotatable second rotating arms, the four second connecting blocks and the base plate, the extension plates move downwards in an arc trajectory. Simultaneously, the relative movement of the two support slide plates causes the two extension plates to move downwards, retract and move into the n-shaped base. When the two extension plates need to be unfolded for use, the dual-output shaft motor is started in reverse. Attached Figure Description

The width of the two extension plates 3 is smaller than the width of the inner side of the n-shaped platform 2. Two pairs of sliding grooves 4 are symmetrically opened inside the n-shaped platform 2. A movable and adjustable support slide plate 5 is installed between each pair of sliding grooves 4. The two support slide plates 5 are located below the two extension plates 3 respectively, and an adjuster 6 is installed between the adjacent support slide plates 5 and the extension plates 3. A dual-shaft motor 7 connected to the two support slide plates 5 is installed in the middle of the top of the base 1.

[0012] Each slide 4 consists of a shallow groove 8 and a deep groove 9. The deep groove 9 is located inside the shallow groove 8. The support slide plate 5 is slidably installed between the two opposite shallow grooves 8. A slider 10 is fixedly installed at one end of the support slide plate 5. The two ends of the slider 10 are slidably installed inside the two opposite deep grooves 9. A threaded shaft 11 is threadedly connected between the middle of the support slide plate 5 and the middle of the slider 10. The opposite ends of the two threaded shafts 11 are fixedly connected to the two output ends of the dual-output shaft motor 7.

[0013] The adjuster 6 includes two pairs of first connecting blocks 12 fixedly installed on the top of the support slide plate 5. An adjusting shaft 13 is rotatably connected between the upper parts of each pair of first connecting blocks 12. A first rotating arm 14 is fixedly connected to both ends of each adjusting shaft 13. A second rotating arm 15 is rotatably connected to one side of each first connecting block 12. Adjacent first rotating arms 14 and second rotating arms 15 are arranged vertically.

[0014] Specifically, as shown in the attached diagram, when it is necessary to retract the two expansion plates 3 to move them into the n-shaped base 2, the dual-output shaft motor 7 is first started to rotate the two threaded shafts 11. The rotation of the two threaded shafts 11 causes the two support slide plates 5 and the sliders 10 on the support slide plates 5 to slide relative to each other inside the shallow groove 8 and the deep groove 9. The relative movement of the two support slide plates 5 will drive the transmission gears 18 on them to move, causing the transmission gears 18 to roll on the toothed plate 21. The rolling movement of the transmission gears 18 will drive one of the adjusting shafts 13 on the support slide plates 5 to rotate. The rotation of 13, through sprocket 19 and chain 20, will drive another adjusting shaft 13 on the support slide plate 5 to rotate, thereby causing the two adjusting shafts 13 on the support slide plate 5 to rotate synchronously, which will drive the four first rotating arms 14 on the support slide plate 5 to rotate downward. At the same time, through the four rotatable second rotating arms 15, the four second connecting blocks 17 and the base plate 16, the extension plate 3 will move downward in an arc trajectory. At the same time, through the relative movement of the two support slide plates 5, the two extension plates 3 will move downward and retract into the n-shaped base 2. When it is necessary to unfold the two extension plates 3 for use, the dual output shaft motor 7 can be started in reverse.
