Description

Technical Field

[0001] The utility model relates to the field of automation equipment, in particular to a novel automatic film cutting machine. Background Art

[0002] After the stone slab comes out of the grinder and polisher, it needs to be covered with a layer of film, especially for almost every piece of artificial stone. The purpose is to keep the stone slab from being scratched and contaminated, and to maintain the bright color and luster of the slab. The coating process is completed on the transition roller table behind the grinder. Because the film is continuous, and the slabs are piece by piece, each piece needs to be cut off to separate them.

[0003] The existing automatic film cutting machine for stone slabs can solve the problem of automatic film cutting of granite or artificial stone slabs with relatively standard shapes and specifications, but it is difficult to handle the irregularities of natural marble slabs.

[0004] The utility model patent with Chinese patent application number 202221732462.9 discloses a fully automatic film cutting machine, including a front transition frame, a rear transition frame, a rear transition frame platform, a drop cylinder, a baffle mechanism and a film cutting knife frame mechanism.

The above utility model is a patent document previously applied for by the applicant. On this basis, the applicant continued to research and innovate, and came up with this solution by changing the cutting method. Utility Model Content

[0005] Therefore, based on the above concept, the utility model proposes a novel automatic film cutting machine, which solves the technical problem that the existing automatic film cutting machine is difficult to perform accurate automatic film cutting on irregular natural marble slabs.

[0007] The drop transition frame is provided with a driving assembly, and the film cutting mechanism is provided on the driving assembly, and is driven up and down by the driving assembly to approach or move away from the drop transition frame;

[0008] The driving assembly comprises a driving assembly articulated support, a lifting cylinder mounting plate, a driving assembly mounting seat, a limiting roller and a lifting cylinder. The lifting cylinder mounting plate is fixedly arranged on the frame of the drop transition frame, the driving assembly articulated support is fixedly arranged on the lifting cylinder mounting plate, a connecting rod is arranged between two driving assembly articulated supports, a lifting cylinder is arranged on the lifting cylinder mounting plate, the driving assembly mounting seat is respectively articulated with the lifting cylinder and the connecting rod, and rotates and rises and falls under the up and down pushing action of the lifting cylinder, and the limiting roller is arranged at the hinge between the lifting cylinder and the driving assembly mounting seat;

[0010] Furthermore, a lifting cylinder is provided on the drop transition rack, and the up and down lifting of the table top of the drop transition rack can be controlled by lifting the lifting cylinder up and down.

[0011] Furthermore, in an initial state, the table height of the plate entry transition rack is flush with the table height of the drop transition rack.

[0012] By adopting the above technical solution, the beneficial effects of the utility model are:

[0013] Compared with the existing automatic film cutting machines for stone slabs, the utility model has a wider range of applications. It can not only solve the problem of automatic film cutting of granite or artificial stone slabs with relatively standard shapes and specifications, but also can cope with irregular natural marble slabs and achieve accurate automatic film cutting.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1-Figure 3 The utility model provides a novel automatic film cutting machine, comprising a board feeding transition frame 1 arranged according to the traveling direction of the assembly line, a stone plate laminating machine 2, a falling transition frame 3 and a film cutting mechanism 4;

[0020] The drop transition frame 3 is provided with a driving assembly 6, and the film cutting mechanism 4 is provided on the driving assembly 6, and is driven up and down by the driving assembly 6 to approach or move away from the drop transition frame 3;

[0021] The driving assembly 6 comprises a driving assembly articulated support 61, a lifting cylinder mounting plate 62, a driving assembly mounting seat 63, a limiting roller 64 and a lifting cylinder 65. The lifting cylinder mounting plate 62 is fixedly arranged on the frame of the drop transition frame 3. The driving assembly articulated support 61 is fixedly arranged on the lifting cylinder mounting plate 62. A connecting rod 7 is arranged between the two driving assembly articulated supports 61. A lifting cylinder 65 is arranged on the lifting cylinder mounting plate 62. The driving assembly mounting seat 63 is respectively articulated with the lifting cylinder 65 and the connecting rod 7, and rotates and rises under the up and down pushing action of the lifting cylinder 65. The limiting roller 64 is arranged at the hinge between the lifting cylinder 65 and the driving assembly mounting seat 63.

[0022] The film cutting mechanism 4 includes a driving motor 41, a driving wheel 42, a driven wheel 43 and a film cutting line 44. The driving motor 41, the driving wheel 42 and the driven wheel 43 are all installed on the driving component mounting seat 63. The driving motor 41 is used to drive the driving wheel 42 to rotate. The film cutting line 44 is wound between the driving wheel 42 and the driven wheel 43, and performs rotational cutting under the rotation drive of the driving wheel 42.

[0023] The drop transition frame 3 is provided with a lifting cylinder 31, and the up and down lifting of the lifting cylinder 31 can control the up and down lifting of the table of the drop transition frame 3. In the initial state, the table height of the plate entry transition frame 1 is flush with the table height of the drop transition frame 3.

[0024] The working mode of the utility model is as follows: the film cutting mechanism 4 is arranged on the drop transition frame 3, and is connected to the frame of the drop transition frame 3 through the jacking cylinder mounting plate 62. The jacking cylinder 65 and the driving component hinge support 61 are fixedly connected to the jacking cylinder mounting plate 62, and the driving component mounting seat 63 is hinged to the driving component hinge support 61, and can be driven to rotate and lift by the jacking cylinder 65. When the detection switch detects that the plate 5 is completely transported to the drop transition frame 3, the lifting cylinder 31 of the drop transition frame 3 drives the table of the drop transition frame 3 to descend. At this time, the film cutting mechanism 4 is driven to rotate and descend through the jacking cylinder 65, so that the limiting roller 64 falls on the surface of the plate 5, and the film cutting line 44 is just aligned with the staggered position of the two plates. The driving motor 41 drives the driving wheel 42 to rotate, so that the film cutting line 44 generates friction that can cut the protective film, thereby completing the film cutting action. After the film is cut, the falling transition frame 3 and the film cutting mechanism 4 are restored to their original positions through the corresponding cylinders at the same time to avoid the plate passing through, and so on, the subsequent plates are all cut through this action.
