[0002] Plastic sheets are sheet-like materials made primarily of plastic. Their core component is a high-molecular polymer (such as synthetic resin), supplemented with fillers, plasticizers, stabilizers, and other additives to optimize performance. Currently, in the subsequent processing of plastic sheets, due to specific customer requirements, it is sometimes necessary to bevel the sheets. However, our current and existing plastic sheet manufacturing processes are not very convenient for bevel positioning, especially during batch processing. This requires significant staff involvement, such as adjusting the sheet angle, positioning tooling, and unloading, resulting in excessive preparation time and potentially affecting the efficiency of plastic sheet cutting and forming.

[0003] Therefore, there is an urgent need for an auxiliary device for molding plastic sheets to solve the above problems. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0023] Figures 1-4 The diagram shown is a complete structural schematic of a plastic sheet forming auxiliary device according to this utility model. Please refer to [link / reference]. Figures 1-4 This embodiment of a plastic sheet molding auxiliary device includes a base 100. The upper end of the base 100 has a guide groove 1001 along its length. A tooling table 200, driven by a drive device, slides inside the guide groove 1001. A material tray 210 is horizontally rotatably mounted on the upper front end of the tooling table 200. A servo motor 230 is located at the bottom of the tooling table 200 and is used to drive the material tray 210 to rotate horizontally. A sheet positioning clamp 300 is provided on one side of the upper end of the tooling table 200. A horizontal rail 500 is provided on one end of the upper part of the base 100 along the width direction of the base 100. A slide block 510 slides inside the horizontal rail 500. A reciprocating drive assembly 600 is used to drive the slide block 510 to move left and right. A cutting device 700 is provided on one side of the slide block 510.

[0024] The inner side of the guide slide 1001 is also provided with an electric actuator 800 for pushing the tooling table 200 to move back and forth along the direction of the guide slide 1001, and the tooling table 200 has sliders on both sides that match the guide slide 1001. The bottom of the material tray 210 has a turntable seat 220 coaxial with it, and the upper part and inner side of the tooling table 200 have mounting grooves 2001 that match the turntable seat 220. The turntable seat 220 is rotatably mounted on the inner side of the mounting groove 2001 by bearings. It can be understood that by rotating the mounting and using the servo motor 230 to drive the turntable seat 220 to rotate, the rotation angle of the turntable seat 220 and the plastic sheet can be precisely controlled. The top side of the tooling table 200 has a rounded scale line 400 coaxial with the material tray 210, and a positioning block 410 is fixed on the upper end of the material tray 210. A laser camera 420 corresponding to the rounded scale line 400 is provided on the free end of the positioning block 410. As the material tray 210 rotates, it drives the laser camera 420 to rotate synchronously. Simultaneously, the laser camera 420 determines the forward and reverse rotation angles of the material tray 210 based on the relative position of the rounded corner scale line 400. Upon receiving feedback, the control unit uses the servo motor 230 to adjust the rotation angle of the material tray 210, making it simple and practical. The sheet material positioning fixture 300 includes a baffle 310 fixed to one side of the top of the material tray 210, a fixing frame 320 fixed to the upper end of the baffle 310, a positioning pressure plate 330 positioned below the horizontal section of the fixing frame 320, and an electric push rod 340 fixed to the upper end of the fixing frame 320 for moving the positioning pressure plate 330 up and down. The baffle 310 provides initial positioning for the plastic sheet material placed on the material tray 210, and the positioning pressure plate 330 fixes the sheet material onto the material tray 210. The reciprocating drive assembly 600 includes a lead screw 610 rotatably mounted at both ends inside the horizontal rail 500, and a servo motor 620 disposed at one end of the horizontal rail 500 and used to drive the lead screw 610 to rotate axially. A cutter head 710 is longitudinally arranged at the output end of the cutting device 700, and a clearance groove 1002, which runs vertically through the upper part of the base 100 and matches the cutter head 710, is provided at one end of the base 100. A controller H is also disposed on one side of the base 100.Specifically, in use, the plastic sheet is placed on the feeding tray 210 and clamped and fixed by the sheet positioning clamp 300. Then, according to the required angle of the sheet, the feeding tray 210 and the angle of the sheet are adjusted in coordination with the servo motor 230, turntable 220, rounded corner scale 400, laser camera 420, and controller H. At this time, the section of the sheet to be cut is suspended at the front end of the feeding tray 210. Then, the electric actuator 800 is used to push the tooling table 200, the feeding tray 210, and the sheet to move, so that the suspended section of the sheet is positioned at the front end of the feeding tray 210. Above the clearance groove 1002, the cutting device 700 is driven to move laterally with the cooperation of the horizontal rail 500 and the reciprocating drive component 600, etc. The cutting disc 710 is used to perform rotary cutting on the plate, thus completing the auxiliary positioning and cutting of the plate. The above operating units can be preset by the controller H. In this way, when using the plate, it can be placed directly on the material tray 210 and positioned by the fixture, and then the device can adjust and cut at an angle by itself. This effectively reduces the problems of excessive preparation time and excessive manual intervention in the prior art, and the processing efficiency is further improved.

In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
