Description

A type of invisible window screen cutting machine Technical Field

[0001] This utility model relates to the field of cutting machine technology, specifically to an invisible window screen cutting machine. Background Technology

[0002] Traditional invisible window screen cutting machines only have a coating mechanism on the front of the cutting mechanism, without any coating treatment on the rear. In practical applications, this type of invisible window screen cutting machine with only a coating mechanism on the front usually encounters the following problem: during the cutting process of the invisible window screen material, the surface of the material on the cutting table at the rear of the cutting mechanism easily becomes covered with cutting debris, oil, etc., making subsequent cleaning difficult.

[0003] In addition, traditional invisible window screen cutting machines usually adopt an integral suction method, that is, the entire cutting table is only a vacuum adsorption area. This integral suction method generally has the following defects: (1) After the invisible window screen material on the cutting table is cut, the cutting table will continue to maintain an integral suction state, which is unnecessary for the already cut invisible window screen material and will cause energy waste. Summary of the Invention

[0004] The purpose of this utility model is to provide an invisible window screen cutting machine to solve the technical problems existing in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0011] Furthermore, a first rotating arm and a first driving cylinder are rotatably connected to the front side of the frame, and a second rotating arm and a second driving cylinder are rotatably connected to the rear side of the frame.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] The present invention will be further described below with reference to the accompanying drawings:

[0036] Referring to Figures 1 to 4, this utility model embodiment provides an invisible window screen cutting machine, including a cutting bed 1, a cutting mechanism 2 slidably disposed on the upper part of the cutting bed 1, a receiving table 3 disposed at the front end of the cutting bed 1, and a feeding table 4 disposed at the rear end of the cutting bed 1. The receiving table 3 is provided with a first coating rod 5 at one end near the cutting bed 1, and the feeding table 4 is provided with a second coating rod 6 at one end near the cutting bed 1. The cutting mechanism 2 is provided with a first coating roller 7 that moves with it at the front end, and a second coating roller 8 that moves with it at the rear end. A first covering film 9 is wound on the first coating roller 7 for covering the cut invisible window screen material, and a second covering film 10 is wound on the second coating roller 8 for covering the invisible window screen material before cutting. The free end of the first covering film 9 is connected to the first coating rod 5, and the free end of the second covering film 10 is connected to the second coating rod 6.

[0037] In this utility model, the receiving table 3 is used to collect the cut invisible window screen pieces to prevent them from falling to the ground; the feeding table 4 is used to smoothly feed the invisible window screen material onto the cutting table 11 to avoid the invisible window screen material to be cut being too long and dragging on the ground, causing scratches on the material surface.

[0038] Specifically, the cutting bed 1 is provided with a cutting table 11 that is connected to the table surface of the receiving table 3 and the table surface of the feeding table 4, respectively, for laying the invisible window screen material to be cut; the cutting table 11 has multiple vacuum adsorption areas for adsorbing the invisible window screen material to be cut onto the cutting table 11; wherein, each vacuum adsorption area is evenly distributed with multiple vacuum adsorption holes 12, and multiple vacuum chambers are provided on the cutting bed 1 and below the cutting table 11, and the multiple vacuum chambers are connected to the multiple vacuum adsorption areas one by one; a multi-chamber vacuum suction device 13 connected to the multiple vacuum chambers is also provided on the cutting bed 1 and below the cutting table 11 for evacuating the multiple vacuum chambers.

[0039] During use, as the cutting mechanism 2 cuts the invisible window screen laid on the cutting table 11 of the cutting bed 1, the first coating roller 7 moves synchronously with the cutting mechanism 2, unfolding the first covering film 9 and laying it on the cut invisible window screen piece; simultaneously, the second coating roller 8 also moves synchronously with the cutting mechanism 2, unfolding the second covering film 10 and laying it on the invisible window screen material before cutting. It should be noted that when the first covering film 9 unfolds, the second covering film 10 rolls up; when the second covering film 10 unfolds, the first covering film 9 rolls up; that is, the unwinding and rewinding actions of the first covering film 9 and the second covering film 10 are reversed. This setting ensures that the invisible window screen material before and after cutting is sealed on the cutting table 11 by the covering film throughout the entire process, avoiding air leakage from the cutting table 11 and affecting the cutting accuracy of the invisible window screen material.

[0040] Specifically, referring to Figures 5 to 8, the multi-chamber vacuum suction device 13 includes a bellows 1301. The bellows 1301 is provided with an air outlet 1302 and multiple air inlets 1303. Multiple interconnected air chambers 1305 are provided inside the bellows 1301. Each air chamber 1305 is connected to a corresponding air inlet 1303. Each air chamber 1305 is connected to a cylinder 1304. The telescopic end of each cylinder 1304 is movably extended inside the corresponding air chamber 1305 and is connected to a cover plate 130 for opening or closing the air inlet 1303. The air outlet 1302 is connected to one of the air chambers 1305, and the multiple air inlets 1303 are connected to multiple vacuum chambers one by one.

[0041] Specifically, the multi-chamber vacuum suction device 13 also includes a vacuum pump (not shown in the figure), which is connected to the outlet 1302.

[0042] Specifically, to improve the sealing between the cover plate 1306 and the air intake 1303, a sealing plate 1307 is provided on the side of the cover plate 1306 away from the cylinder 1304. With the sealing plate 1307, when the cover plate 1306 blocks the air intake 1303 under the push of the cylinder 1304, a sealed contact is formed between the sealing plate 1307 and the inner wall of the air box 1301 surrounding the air intake 1303, preventing gas leakage from inside the air box 1301.

[0043] The working principle of the multi-chamber vacuum suction device 13 is as follows: In use, the outlet 1302 is first connected to the vacuum pump through the vacuum suction pipe, and the multiple suction ports 1303 are each connected to the multiple vacuum chambers through a suction pipe. Then, the vacuum pump is started to perform the suction operation, and the cylinders 1304 are activated sequentially as the cutting mechanism 2 moves. Specifically, when the cutting mechanism 2 moves to the position of the first vacuum adsorption area on the cutting table 11, the cylinder 1304 corresponding to the first vacuum adsorption area is activated to open the suction port 1303 connected to the first vacuum adsorption area, while keeping the remaining suction ports 1303 closed. Similarly, when the cutting mechanism 2 moves to the position of the second to Nth vacuum adsorption areas, the cylinder 1304 corresponding to the second to Nth vacuum adsorption areas is activated to open the suction ports 1303 corresponding to the second to Nth vacuum adsorption areas, while keeping the remaining suction ports 1303 closed.

[0044] Under the premise of keeping the total suction volume unchanged, compared with the traditional one-piece suction invisible screen cutting machine, the invisible screen cutting machine provided by this utility model will have an adsorption effect on the invisible screen in each vacuum adsorption area on the cutting table 11 that is N times greater than the adsorption effect on the invisible screen on the cutting table of the traditional one-piece suction invisible screen cutting machine. The number of N is determined by the number of vacuum adsorption areas.

[0045] Specifically, the cutting mechanism 2 includes a frame 201 slidably connected to the cutting bed 1, an electric cutting head 202 slidably connected to the frame 201, and a thermal machine (not shown in the figure) fixedly connected to the electric cutting head 202. A first coating roller 7 is rotatably connected to the front of the frame 201 to unfold the first covering film 9 and coat the cut invisible window screen material. A second coating roller 8 is rotatably connected to the rear of the frame 201 to unfold the second covering film 10 and coat the uncut invisible window screen material. The thermal machine automatically prints labels, which are then automatically applied to the invisible window screen material laid on the cutting table 11, achieving the purpose of automatically labeling the cut invisible window screen material.

[0046] Specifically, a first rotating arm 14 and a first driving cylinder 15 are rotatably connected to the front side of the frame 201, and a second rotating arm 16 and a second driving cylinder 17 are rotatably connected to the rear side of the frame 201. A first coating roller 7 is connected to the free end of the first rotating arm 14, and a second coating roller 8 is connected to the free end of the second rotating arm 16. The output end of the first driving cylinder 15 is hinged to the first rotating arm 14 to drive the first rotating arm 14 to rotate, and the output end of the second driving cylinder 17 is hinged to the second rotating arm 16 to drive the second rotating arm 16 to rotate. The first rotating arm 14 is used to adjust the height of the first coating roller 7 according to actual needs; the second rotating arm 16 is used to adjust the height of the second coating roller 8 according to actual needs.

[0047] Specifically, a coil spring (not shown in the figure) is sleeved on the central shaft of both the first coating roller 7 and the second coating roller 8. One end of the coil spring on the central shaft of the first coating roller 7 is connected to the first coating roller 7, and the other end is connected to the first rotating arm 14. One end of the coil spring on the central shaft of the second coating roller 8 is connected to the second coating roller 8, and the other end is connected to the second rotating arm 16.

[0048] Specifically, the left and right side walls of the cutting bed 1 are provided with first tracks 18 extending along their length, and the frame 201 is slidably connected to the first tracks 18 of the cutting bed 1.

[0049] Specifically, a second track 19 extending along its length is provided on the frame 201, and the electric cutting head 202 is slidably connected to the second track 19.

[0050] Specifically, first anti-collision blocks 20 are provided on both the left and right side walls of the cutting bed 1 to limit the forward and backward movement of the cutting mechanism 2 as a whole; second anti-collision blocks 21 are provided on both the left and right ends of the frame 201 to limit the left and right movement of the electric cutting head 202.

[0051] It should be noted that the invisible window screen cutting machine provided by this utility model also includes a controller, which is used to control the operation of the entire cutting machine. Since the controller is prior art, it will not be described in detail in this application. Secondly, the cutting bed 1 and cutting mechanism 2 mentioned above are also prior art, and therefore will not be described in detail in this application either. The key protection points of this utility model are: the film-coating mechanism and the multi-chamber vacuum suction device arranged in front of and behind the cutting bed.

[0052] Finally, it should be noted that the above description is only an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
