DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1 - Figure 5 A high-efficiency plate feeding mechanism of a platemaking machine includes a machine body 1, a horizontal plate 2 is fixedly connected to the front side of the machine body 1, a lifting assembly is connected to the bottom of the horizontal plate 2, the lifting assembly passes through the horizontal plate 2 and is connected to a placement plate 3, a telescopic assembly is arranged in the placement plate 3, two clamping plates 4 are connected at both ends of the telescopic assembly, support rods 5 are fixedly connected to both sides of the machine body 1, a plate feeding assembly is connected between the two support rods 5, and the plate feeding assembly is located above the placement plate 3.

[0023] like Figure 1 - Figure 5 As shown, the efficient plate-feeding mechanism of a plate-making machine in the utility model is similar to the structure of an existing plate-making machine, such as a plate-making machine disclosed in the patent with announcement number CN220923520U. The main improvement of the utility model is to avoid the problem of bottom plate tilting that may be caused by manual feeding, improve the plate-making quality, and reduce the workload of workers, such as Figures 1 to 5As shown, when the efficient plate feeding mechanism of the plate making machine in the utility model is in use, multiple material plates are placed on the placement plate 3, and the placement plate 3 is lifted upward by the lifting assembly, so that the uppermost material plate on the placement plate 3 is in contact with the plate feeding assembly, and then the uppermost material plate is sent into the machine body 1 for plate making processing by the plate feeding assembly. At the same time, during the plate feeding, the material plate can be clamped in the middle position by the clamping plates 4 on both sides, and the material plate entering the machine body 1 is kept horizontally to avoid the material plate tilting and affecting the plate making processing effect.

[0024] like Figure 1 - Figure 5 As shown, the lifting assembly includes a lifting cylinder 6, a linkage plate 7 and four lifting rods 8. The lifting cylinder 6 is fixedly connected to the center position of the bottom of the horizontal plate 2. The output end of the lifting cylinder 6 is downward and fixedly connected to the center position of the linkage plate 7. The four corners of the linkage plate 7 close to the lifting cylinder 6 are respectively fixedly connected to the four lifting rods 8. The ends of the four lifting rods 8 away from the linkage plate 7 all penetrate the horizontal plate 2 and are respectively fixedly connected to the four corners of the placement plate 3. By starting the lifting cylinder 6, the linkage plate 7 at the bottom is driven to move up and down, thereby driving the four lifting rods 8 to slide up and down in the horizontal plate 2 at the same time, and then driving the upper placement plate 3 to move up and down. The four lifting rods 8 can ensure that the placement plate 3 will not tilt when moving up and down, and the lifting process is more stable.

[0025] like Figure 1 - Figure 5 As shown, the telescopic assembly includes an outer gear ring 9 and two racks 10, a rotating cavity 301 is opened in the middle position of the placement plate 3, the outer gear ring 9 is located in the rotating cavity 301 and is rotatably connected to the rotating cavity 301, telescopic grooves 302 are opened on both sides of the rotating cavity 301, and both ends of the two telescopic grooves 302 are of through-design, and the two racks 10 are slidably connected with the two telescopic grooves 302 respectively, and the sides of the two racks 10 close to the outer gear ring 9 are meshed with the outer gear ring 9, the two telescopic grooves 302 are away from the side of the cross plate 2, and the ends away from each other are penetrated with limiting grooves 303, the ends of the two racks 10 away from each other, and the sides close to the adjacent limiting grooves 303 are fixedly connected with the limiting slider 11, the two limiting sliders 11 are respectively connected with the two limiting grooves 303 in an arc, the two limiting sliders 11 are respectively fixedly connected with the two limiting grooves 303 on the side away from the cross plate 2, and the two clamps 4 are slidably connected to the placement plate 3. By rotating the middle outer gear ring 9, the two meshing racks 10 can always keep moving synchronously when moving in the telescopic groove 302, and cooperate with the two clamping plates 4 to always clamp the material sheet on the placement plate 3 in the middle position.

[0026] like Figure 4 and Figure 5As shown, a fixed shaft 12 is fixedly connected to the center position of the upper and lower sides of the rotating cavity 301, and a coil spring 13 is sleeved on the outer side of the fixed shaft 12, one end of the coil spring 13 is fixedly connected to the fixed shaft 12, and the other end is fixedly connected to the inner side of the outer gear ring 9. When the two clamping plates 4 move away from each other, the outer gear ring 9 is driven to rotate, and then the pulling on the two clamping plates 4 is released. At this time, the coil spring 13 drives the outer gear ring 9 to return and rotate, and then drives the two racks 10 to move to the inner side of the telescopic slot 302, driving the two clamping plates 4 to approach each other, and then clamping the material plate on the placement plate 3 in the middle position of the placement plate 3.

[0027] like Figure 1 - Figure 3 As shown, the plate feeding assembly includes a plate feeding motor 14, a driving rod 15 and a plurality of plate feeding wheels 16. The two ends of the driving rod 15 are rotatably connected to the two support rods 5 respectively. The plate feeding motor 14 is fixedly connected to one side of the support rods 5 away from the other support rod 5. The output shaft of the plate feeding motor 14 is fixedly connected to the driving rod 15. The plurality of plate feeding wheels 16 are all sleeved with the driving rod 15 and fixedly connected to the driving rod 15. When the placement plate 3 is lifted and the material sheet at the top of the placement plate 3 is pressed against the plate feeding wheel 16, the plate feeding motor 14 is started to drive the driving rod 15 to rotate, and then drive the plurality of plate feeding wheels 16 to rotate, so that the material sheet is rolled and transported in the direction of the machine body 1 through the friction between the plate feeding wheel 16 and the extruded material sheet, and the automatic plate feeding operation of the material sheet can be completed.

[0028] like Figure 1 - Figure 3 As shown, the plate feeding wheel 16 is a rubber wheel, and the height difference between the bottom of the plate feeding wheel 16 and the feed inlet of the machine body 1 is the thickness of a plate. Therefore, even if the plate feeding wheel 16 drives the plate to move, only the top plate will enter from the feed inlet of the machine body 1. The use of the rubber wheel can prevent the plate feeding wheel 16 from slipping when in contact with the plate, thereby improving the stability of the plate feeding operation.

[0029] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
