The positioning assembly 5 comprises a dovetail groove 502 arranged on one side of the connecting plate 6. The dovetail groove 502 provides a track for sliding of a dovetail block 504, so that the dovetail block 504 can only move in a specific direction, and accurate control of a positioning strip 505 is realized. The dovetail groove 502 is in contact and sliding connection with the dovetail block 504.

The dovetail block 504 is fixedly connected with the positioning strip 505 on the outside. The positioning strip 505 can position the material placed on the placing plate 7. By abutting the material against the top of the placing plate 7, it is ensured that the material will not be displaced during feeding. The main body 2 of the laminator is fixedly connected with an extrusion strip 501. When the moving frame 3 is attached to the main body 2 of the laminator, the extrusion strip 501 extrudes the positioning strip 505, so that the positioning strip 505 moves upward, thereby releasing the positioning of the material, so that the material can be smoothly fed into the main body 2 of the laminator.

[0033] Referring to Figure 3The placing plate 7 is provided with a discharging assembly, which is used to automatically feed the positioned material into the feeding port of the laminator main body 2, realizes the automatic feeding process, improves the work efficiency, and comprises an extension plate 803, which provides a stable mounting position for the electric cylinder 802 and ensures that the electric cylinder 802 will not shake or displace during the working process. The extension plate 803 is fixedly connected to the top of the placing plate 7, the back surface of the extension plate 803 is fixedly installed with the electric cylinder 802, the electric cylinder 802 provides power for the movement of the push plate 801, can accurately control the moving speed and distance of the push plate 801, realizes the accurate pushing of the material, the telescopic end of the electric cylinder 802 is movably penetrated through the back surface of the extension plate 803 and is fixedly connected with the push plate 801, the push plate 801 can move on the top of the placing plate 7 under the driving of the electric cylinder 802, pushes the material placed on the placing plate 7 into the feeding port of the laminator main body 2, and the bottom of the push plate 801 is in contact with the top of the placing plate 7, so that the push plate 801 can be closely attached to the placing plate 7 when pushing the material, and the material is prevented from deviating or jamming during the pushing process.
[0034] Working principle: the material to be processed is laid on the placement plate 7, and the positioning strip 505 is pushed upwards in sequence, so that the positioning strip 505 moves upwards in the dovetail groove 502 through the dovetail block 504, and the third spring 503 is pressed by the dovetail block 504, so that the gap between the bottom of the positioning strip 505 and the top of the placement plate 7 is reserved for the material, then the positioning strip 505 is released, and the longitudinal elastic potential of the third spring 503 drives the positioning strip 505 to move downwards, so that the bottom of the positioning strip 505 tightly presses the material on the top of the placement plate 7, thereby realizing the positioning effect of the material. After the material installation is completed, the electric guide rail 403 is started, so that the electric guide rail 403 drives the moving frame 3 to move towards the direction of the laminator main body 2. At this time, the moving wheel 405 slides in the guide groove 402 opened at the top of the guide strip 401. When the moving wheel 405 passes through the trapezoidal block 404, the moving wheel 405 drives the movable rod 406 to move upwards, and the second toothed plate 4015 moves upwards along the movable rod 406. Since the second toothed plate 4015 is engaged with the second gear 4016, the second toothed plate 4015 drives the second gear 4016 to rotate, the second gear 4016 drives the rotating rod 4017 to rotate, and the rotating rod 4017 drives the first gear 4010 to rotate. Since the first gear 4010 is engaged with the first toothed plate 409, the first gear 4010 drives the first toothed plate 409 to move downwards, so that the first toothed plate 409 and the second toothed plate 4015 move in opposite directions. The first toothed plate 409 drives the lifting rod 408 to slide downwards in the sliding hole, and further drives the two tension rollers 4012 to move downwards. As the moving wheel 405 continuously moves upwards on the inclined surface of the trapezoidal block 404, until the tension rollers 4012 contact the top of the material, the two tension rollers 4012 rotate around the surface of the lifting rod 408 through the first connecting rod 4011 and the second connecting rod 4018. The first connecting rod 4011 and the second connecting rod 4018 stretch the second spring 4013 in the process of rotating outward, and the two tension rollers 4012 realize tensioning of the material, thereby avoiding wrinkles of the material. After the laminating effect of the laminator main body 2, the moving wheel 405 moves downwards under the action of the inclined surface of the trapezoidal block 404, and the elastic potential of the second spring 4013 realizes the reset effect of the two tension rollers 4012. When the moving frame 3 is attached to the laminator main body 2, the inclined surface of the pressing strip 501 presses the inclined surface of the positioning strip 505, so that the positioning strip 505 moves upwards, thereby releasing the positioning of the material on the top of the placement plate 7. Then the electric cylinder 802 is started, and the extension end of the electric cylinder 802 drives the push plate 801 to move on the top of the placement plate 7, and the push plate 801 pushes the material on the top of the placement plate 7 into the feeding port of the laminator main body 2, thereby realizing the feeding process of the material. Finally, the material is coated by the laminator main body 2.
[0035] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
