Description

Technical Field

[0001] The utility model relates to the technical field of film laminating machine cutting, in particular to an automatic cutting mechanism for a film laminating machine. Background Art

[0002] Film laminating machines can be divided into two categories: immediate coating film laminating machines and pre-coated film laminating machines. They are special equipment for paper and film. Immediate coating film laminating machines include three parts: gluing, drying, and hot pressing. They have a wide range of applications, stable and reliable processing performance, and are widely used film laminating equipment in China. Pre-coated film laminating machines do not have gluing and drying parts, are small in size, low in cost, and flexible and convenient to operate. They are suitable for not only the film laminating processing of large quantities of printed products but also the film laminating processing of small quantities and scattered printed products such as automated desktop office systems, and have great development prospects. Some products after film lamination need to be cut into certain sizes for convenient transportation or subsequent processing. Since the existing film laminating machines are prone to causing the products to shift during transportation, the cut products are skewed when cutting, increasing the probability of defective products. Summary of the Utility Model

[0003] In order to solve the above technical problems, the utility model specifically adopts the following technical solutions.

[0004] Design an automatic cutting mechanism for a film laminating machine, including a frame. Along the conveying direction of the film on the frame, a first conveyor belt, a cutting table, and a second conveyor belt are successively arranged, and the upper surfaces of the three are located on the same horizontal plane. Above the front end of the frame, there is a film supply roller. On the upper surface of the frame near the first conveyor belt, there is a first limiting roller, and on the upper surface near the second conveyor belt, there is a second limiting roller. The second limiting roller is located at the rear end of the second conveyor belt.

[0005] On the opposite front and rear side surfaces of the frame, a plurality of guiding components are respectively arranged corresponding to each other. Above the cutting table, there is a cutting component. The cutting component includes a fixing frame straddling the front and rear sides of the frame. On the cross beam of the fixing frame, there is a telescopic cylinder. The telescopic end of the telescopic cylinder passes through the cross beam and is connected with an installation frame. In the middle position of the installation frame, there is a fixing plate connected. At the bottom of the fixing plate, there is a cutting knife. On both sides of the installation frame, there are respectively connected positioning components.

[0006] Preferably, the guiding component includes grooves opened on the opposite front and rear side surfaces of the frame. In the grooves, a plurality of guiding rollers in contact with both sides of the product are rotatably arranged.

[0007] Preferably, the positioning component includes a fixed sleeve, a compression spring sequentially arranged in the fixed sleeve, a limiting plate slidably connected with the fixed sleeve, and a movable rod with one end extending out of the bottom of the fixed sleeve movably. At the bottom of the movable rod, there is a pressing plate.

[0008] Preferably, a flexible sleeve is provided on the outer surface of the pressing plate.

[0009] Preferably, the cutting knife is installed on the fixing plate by bolts.

[0010] The beneficial effects of the utility model are as follows:

[0011] The utility model utilizes a plurality of guide rollers on both sides of the frame to prevent the product from shifting when the first conveyor belt and the second conveyor belt convey the product and the product after film covering, thus avoiding affecting the deviation of the product during cutting and ensuring the stable outflow of the product from the second conveyor belt.

[0012] The utility model uses the positioning components on both sides of the cutting knife to press the product after film covering on the cutting table. When pressing and positioning, the pressing plate abuts against the product, so that the compression spring is in a compressed state. Under the action of the compression spring, the pressing plate presses the product tightly for positioning, thereby making the cutting knife more stable during cutting and not easily causing the product to shift, thus preventing cutting deviation.

Detailed Description of the Preferred Embodiments

[0019] The following is a description of the preferred embodiments of the utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the utility model and are not intended to limit the utility model. Embodiment

[0020] An automatic cutting mechanism for a film laminating machine, such asFigures 1 to 5 As shown in the figure, it includes a frame 1. Along the conveying direction of the film 4 on the frame 1, a first conveyor belt 2, a cutting table 12, and a second conveyor belt 13 are successively arranged, and the upper surfaces of the three are located on the same horizontal plane. Above the front end of the frame 1, there is a film roller 3 for supplying the film. On the upper surface of the frame 1 near the first conveyor belt 2, there is a first limiting roller 5. Near the upper surface of the second conveyor belt 13, there is a second limiting roller 14, and the second limiting roller 14 is located at the rear end of the second conveyor belt 13. The first limiting roller 5 facilitates the conveying of the film 4, and the second limiting roller 14 facilitates the conveying of the product 15 after film covering.

[0021] The guiding component 6 includes grooves 61 opened on the opposite front and rear side surfaces of the frame 1, and a plurality of guiding rollers 62 in contact with both sides of the product 15 are rotatably arranged in the grooves 61. Under the guiding and limiting of the plurality of guiding rollers 62, the product 15 after film covering is prevented from shifting, which ultimately affects skewing during cutting and thus affects the yield of the product 15.

[0022] Above the cutting table 12, there is a cutting component. The cutting component includes a fixed frame 7 straddling the front and rear sides of the frame 1. On the cross beam of the fixed frame 7, there is a telescopic cylinder 8. The telescopic end of the telescopic cylinder 8 passes through the cross beam and is connected with a mounting frame 10. In the middle position of the mounting frame 10, there is a fixed plate 11 connected. At the bottom of the fixed plate 11, there is a cutting knife 16. The cutting knife 16 is installed on the fixed plate 11 through bolts, which is convenient for the installation of the cutting knife 16.

The positioning component 9 includes a fixed sleeve 91, a compression spring 92 successively arranged in the fixed sleeve 91, a limiting plate 94 slidably connected with the fixed sleeve 91, and a movable rod 93 with one end extending out of the bottom of the fixed sleeve 91. At the bottom of the movable rod 93, there is a pressing plate 95. On the outer surface of the pressing plate 95, there is a flexible sleeve, such as rubber, which can avoid scratching the film. The product 15 after film covering is pressed by the pressing plate 95, so as to facilitate the stable cutting of the cutting knife 16.

[0024] The product 15 cut by the present utility model can be cardboard. Specifically during work, when the product 15 is conveyed backward on the first conveyor belt 2, it is guided and limited by the guiding rollers 62 on the front and rear sides, so as to prevent the product 15 from shifting, which is convenient for the film 4 to better cover the product 15. Then the product 15 and the film 4 continue to be conveyed backward together. When they are conveyed to a suitable position on the cutting table 12, the telescopic cylinder 8 is started to drive the fixed frame 7 to move downward until the pressing plate 95 contacts the product 15. At this time, the cutting knife 16 cuts the product 15 after film covering together, and it is conveyed backward by the second conveyor belt 13. During the conveying process, it passes through the guiding rollers 62 on both sides to prevent the product 15 from shifting. Finally, after passing through the second limiting roller 14, it directly flows out from the second conveyor belt 13.

[0025] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
