Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1-4 , a laminating machine that is convenient for feeding and collecting paper, includes a workbench 1, a loading assembly and a laminator 18, the four corners of the workbench 1 are provided with supporting legs 2, the workbench 1 is provided with the laminator 18 and two groups of symmetrically arranged loading assemblies, the loading assemblies are arranged on the front and back sides of the laminator 18, the loading assembly includes side panels 3, a top panel 4, a first motor 5, positive and negative threaded screws 6, a slide plate 7, a turntable 8, an elastic member, a baffle 9, a spline 10, a carrying roller 11 and a second motor 12, the side panels 3 are arranged in two groups symmetrically on the workbench 1, the two groups of side panels 3 are also provided with the top panel 4, and a slide plate 7 is provided below the top panel 4. The groove is provided with the forward and reverse screw 6, the first motor 5 passes through the top plate 4 and is connected to the forward and reverse screw 6, the slide plate 7 is set to two groups of symmetrical arrangements, the upper part of the slide plate 7 extends into the slide groove and is connected to the forward and reverse screw 6, the two groups of slide plates 7 are also provided with a turntable 8 near the center end of the top plate 4, the output end of the second motor 12 passes through a group of slide plates 7 and is connected to a group of turntables 8, the two ends of the elastic member are respectively connected to the turntable 8 and the baffle 9, the baffle 9 is provided with the spline 10 near the center end of the top plate 4, and the left and right sides of the supporting roller 11 are symmetrically provided with keyways adapted to the spline 10.

[0024] In this embodiment, the laminator 18 includes a film frame, a film supply device and a tensioning device to ensure that the protective film is stably bonded to the paper. It is a device available on the market and will not be described in detail herein.

[0025] The support leg 2 provides stable support for the workbench 1, and the top plate 4 arranged on the side plate 3 further expands the structural space. The sliding groove arranged below the top plate 4 provides an installation and movement track for the positive and negative screw rod 6 and the sliding plate 7 connected thereto, and limits the movement direction of the sliding plate 7, so that the sliding plate 7 can only move linearly along the sliding groove. The first motor 5 penetrates through the top plate 4 and is connected with the positive and negative screw rod 6. When the first motor 5 starts to operate, the positive and negative screw rod 6 is driven to rotate based on the rotary power output of the motor. The special structure of the positive and negative screw rod 6 is that the rotation directions of the threads on the two sides are opposite. The two groups of symmetrically arranged sliding plates 7 extend into the sliding groove above and are threadedly connected with the positive and negative screw rod 6. According to the screw transmission principle, when the positive and negative screw rod 6 rotates, the two groups of sliding plates 7 will move linearly in opposite directions or away from each other. The spacing between the two groups of sliding plates 7 becomes smaller. The spline 10 is inserted into the key groove. The two groups of sliding plates 7 continue to feed until the elastic member cannot be retracted. The turntable 8 arranged at one end of the sliding plate 7 close to the center of the top plate 4 is driven to rotate by the second motor 12. The output end of the second motor 12 penetrates through one group of sliding plates 7 and is connected with one group of turntables 8. In this way, when the second motor 12 starts, the turntable 8 can be driven to rotate. The elastic member (composed of a spring 14 sleeved on an extension rod 15, the spring 14 provides elastic force, and the extension rod 15 ensures the stability of the extension direction) plays a role in buffering and connecting. Under normal conditions, the elastic member keeps the baffle 9 and the turntable 8 in a relatively stable connection relationship. The load roller 11 can rotate with the turntable 8.

[0026] In actual use, the sliding plate 7 away from the center of the top plate 4 is further provided with a guide rod 13 penetrating through the side plate 3, and the guide rod 13 is arranged below the second motor 12. The guide rod 13 penetrating through the side plate 3 is arranged at the end of the sliding plate 7 away from the center of the top plate 4, and it is arranged below the second motor 12. The function of the guide rod 13 is to further ensure the stability of the movement of the sliding plate 7. When the sliding plate 7 moves linearly along the positive and negative screw rod 6, the guide rod 13 moves synchronously along the corresponding hole or groove on the side plate 3, supporting and guiding the sliding plate 7 from the side, preventing the sliding plate 7 from deviating or shaking during movement, and ensuring that the sliding plate 7 can accurately and stably move towards or away from each other according to the rotation of the positive and negative screw rod 6, thereby ensuring the reliable operation of the entire load assembly.

[0027] The first motor 5 and the second motor 12 are both servo motors with stable control.

[0028] In actual use, the bearing roller 11 is provided with a protective plate 16 on the left and right sides to ensure that the paper on the bearing roller 11 is stably stored or output. When the paper is placed on the bearing roller 11 for paper collection or paper feeding operation, the protective plate 16 can limit the movement range of the paper in the axial direction, avoid the paper from running off or falling off, and make the paper enter or exit the laminator 18 along the predetermined direction, so that the laminating work can be orderly carried out, and the quality and efficiency of the laminating work are improved.

[0029] In the embodiment, the side plate 3 is provided with a reinforcing rib 17 at the front and rear ends of the side plate 3 away from the top plate 4, so as to ensure the strength of the side plate 3.

[0030] When the gap between the two groups of sliding plates 7 becomes larger, the elastic member can be extruded to stably support the bearing roller 11, so as to stably disassemble the bearing roller 11.

[0031] In this document, the term "embodiment" means that the specific features, structures or characteristics described in connection with the embodiment can be included in at least one embodiment of the application. The term "embodiment" appearing in various places in the specification does not necessarily refer to the same embodiment, and does not particularly limit the independence or association between the other embodiments.
