Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of covering machines and relates to a covering machine, in particular to a seam avoidance covering machine. Background Art
[0002] The coating machine is used to coat the surface of the sheet material. When the coated sheet material is a door frame, due to its small width, the purchased film material is a whole sheet with a wider width. Therefore, the film material needs to be cut into multiple strips of width that match the door frame in advance, and then the cut film material is connected and wound on the roller for continuous coating. This will cause seams in the film material. The purchased film material will have a blank part at the beginning and end to protect the pattern on the film material. Therefore, the seam part, that is, the blank part, has a significant color difference from the pattern part, and the seam needs to be avoided during coating. In the existing technology, in order to prevent the seam from being coated on the door frame, a person is required to be responsible for the operation. When it is observed that the seam may be coated on the door frame, the movement of the door frame is manually stopped, and the film material is allowed to move for a distance before the door frame is moved. This not only relies on human experience and has low accuracy, but also greatly reduces production efficiency. At the same time, if the estimation is inaccurate, a long distance of empty travel is required, wasting film material. Utility Model Content
[0003] In order to solve the above deficiencies in the prior art, the present invention aims to provide a seam avoidance covering machine to achieve the purpose of automatically avoiding the seams of film materials, improving production efficiency and reducing waste.

[0026] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and understand the present invention and are not intended to limit the present invention.
[0027] Embodiment A seam avoidance covering machine
[0028] like Figure 1 As shown, this embodiment is an improvement on the coating machine in the prior art. The other structures of the coating machine remain unchanged. The existing coating machine includes a plate conveying device 1, a film unwinding device 2, a glue coating device 4, and a control device. The film unwinding device 2 is located above the plate conveying device 1 and includes a discharge shaft for placing a film roll, and also includes three guide rollers 3. The film roll is fixed to the discharge shaft so that the film material passes over the three guide rollers 3 and adheres to the plate 9. The glue coating device 4 is located between the film unwinding device 2 and the plate conveying device 1 and is provided on the side of the film material that is in contact with the plate 9. It is used to apply glue to the film material so that the film material adheres to the plate 9. The above are all prior art, and other devices will not be described in detail.
[0029] A seam detection device 5 is provided along the film material conveying path. The seam detection device 5 is a color recognition detector, located on the patterned side of the film material, for identifying the film material's seams. To install the seam detection device 5, a vertical pole is fixed to the sheet material conveying device 1, and the seam detection device 5 is mounted on the vertical pole.
[0030] The plate conveying device 1 is fixed with a lifting device 7, a pressing device 8 and a baffle 6. Figure 1 As shown, the lifting device 7 is arranged below the plate conveying device 1, and is used to lift the plate 9 on the plate conveying device 1 so that one end of the plate 9 moved to the position of the lifting device 7 is higher than the plate 9 normally conveyed. The pressing device 8 is arranged above the conveying device, opposite to the lifting device 7. The baffle 6 is fixed above the conveying device, and the baffle 6 is located between the film placing device 2 and the pressing device 8. There is a gap between the baffle 6 and the plate conveying device 1. The plate 9 normally conveyed by the plate conveying device 1 can pass through the gap, but the plate 9 lifted by the lifting device 7 is against the baffle 6 and cannot pass through the gap, as shown in FIG. Figure 2 As shown, after the pressing device 8 presses down the raised plate 9, the plate conveying device 1 drives the plate to pass through the gap.
[0031] like Figure 3 As shown, the lifting device 7 includes a mounting block 71, an elastic member, and a roller 75. The elastic member is a spring 73. The mounting block 71 is fixed to the plate conveyor 1 via a vertical rod. The mounting block 71 is provided with a through hole, into which a guide rod 72 is slidably connected. To improve the stability of the sliding connection and reduce friction, in this embodiment, the mounting block 71 and guide rod 72 are directly combined to form a linear guide structure. The mounting block 71 acts as the slider of the linear guide, and the guide rod 72 acts as the guide shaft of the linear guide. The slider is fixed, and the guide shaft moves up and down along the slider. The spring 73 is sleeved on the guide rod 72. One end of the spring 73 abuts the mounting block 71, and the other end is fixedly connected to the guide rod 72. To facilitate the assembly of the roller 75, a U-shaped seat 74 is fixed to the end of the guide rod 72 fixed to the spring 73. The roller 75 is rotatably connected to the U-shaped seat 74, contacting the bottom of the plate 9. The lifting and lowering of the U-shaped seat 74 causes the spring 73 to expand and contract, and at the same time, causes the guide rod 72 to move along the mounting block 71, thus providing a guide. A limiting piece 76 is fixedly provided at the other end of the guide rod 72 , and the limiting piece 76 abuts against the mounting block 71 to prevent the spring 73 from failing and the guide rod 72 from driving the roller 75 to rise too high.
[0032] like Figure 4 As shown, the downward pressure device 8 is located above the plate conveyor 1 and includes a lifting drive device, a mounting base 82, and a pressure roller 83. The lifting drive device is fixed to the plate conveyor 1 via a vertical rod. The lifting drive device can be a cylinder 81 or an electric push rod. In this embodiment, the cylinder 81 is used. The mounting base 82 is fixed to the telescopic rod of the cylinder 81. The pressure roller 83 is rotatably mounted on the mounting base 82. The pressure roller 83 and the roller 75 are arranged in a vertically opposed relationship.
[0033] The electrical signal of the seam detection device 5 is transmitted to the pressing device 8 through the control device, that is, the signal output end of the seam detection device 5 is connected to the signal input end of the control device, and the signal output end of the control device is connected to the signal input end of the cylinder 81 of the pressing device 8. When the seam detection device 5 detects the seam, it transmits the signal to the cylinder 81, and the cylinder 81 drives the pressure wheel 83 to press down the plate 9. The spring 73 is compressed, and the roller 75 moves downward, so that the plate 9 falls on the plate conveying device 1, and after passing through the gap under the baffle 6, it is conveyed normally along the plate conveying device 1.
[0034] When using this embodiment, the plate 9 moves along with the plate conveying device 1, as shown in FIG. Figure 1 As shown, when it moves to the roller 75 of the lifting device 7, one end of the plate 9 rises along the roller 75, and after rising, it hits the baffle 6 and cannot move forward. When the seam detection device 5 detects the seam of the film material, it transmits a signal to the cylinder 81 of the pressing device 8, as shown in FIG. Figure 2 As shown, the cylinder 81 presses down the sheet 9, compressing the spring 73 of the lifting device 7, causing the roller 75 to descend, allowing the sheet 9 to smoothly pass through the gap between the baffle 6 and the sheet conveying device 1. When the tail of the sheet 9 disengages from the roller 75, the roller 75 automatically returns to a position higher than the sheet conveying device 1 under the action of the spring 73. Through adjustment, the sheet 9 pauses at the position of the baffle 6 for 1-2 seconds, and the seam detection device 5 will detect the seam. During the pause time, the seam of the film material is exactly between the front and rear sheets 9, in an idle state, so that the seam will not overlap with the previous sheet 9, nor will it overlap with the next sheet 9, successfully avoiding the position of the seam.
[0035] It should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art may still modify the technical solutions described in the above embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
