Description

Technical Field

[0001] The utility model belongs to the field of sample cutting equipment, in particular to a thin film pneumatic sample cutting machine. Background Art

[0002] In some film manufacturing companies, a portion of the produced film often needs to be cut out for quality inspection or delivered to customers as samples. Therefore, there are certain requirements for the shape and regularity of the cut film. The current common practice is to place the film on a soft surface, and the staff will press a hard plate with a blade on the film, so that the film can be cut in the shape of the blade on the hard plate.

[0003] There are some problems in the above-mentioned film cutting method. The first is that the hard plate with blades is manually pressed for cutting. The different blades on the plate are unevenly stressed when cutting the film, and the edges of the cut film will have a wire drawing phenomenon, which is not beautiful. The second is that each time the film is cut, the film needs to be manually replaced or moved. This cutting method is time-consuming and labor-intensive, and greatly affects work efficiency. Therefore, it is necessary to provide a film pneumatic cutting machine that can efficiently and neatly cut films. Utility Model Content

[0004] The utility model aims to provide a pneumatic film cutting machine to solve the problem that when a hard plate with a blade is manually pressed for cutting, different blades on the plate are subjected to uneven force when cutting the film, and the edges of the cut film will have a wire drawing phenomenon, which is not beautiful. In addition, each time the film is cut, the film needs to be manually replaced or moved. This cutting method is time-consuming and labor-intensive, which greatly affects the technical problem of work efficiency.

[0005] To achieve the above purpose, the specific technical solution of the utility model is as follows:

[0006] A pneumatic film cutting machine is used for automatically cutting and sampling film-like materials, including a conveying component and a cutting component. The conveying component includes a base and a conveyor belt. The cutting component includes a frame, a telescopic rod and a sampling plate. The cutting component is mounted above the conveyor belt through the frame. One end of the telescopic rod is fixedly connected to the frame and the other end is detachably connected to the sampling plate. The telescopic direction of the telescopic rod is perpendicular to the conveying direction of the conveyor belt. A cutting blade is fixed on the surface of the sampling plate opposite to the conveyor belt. With such a design, the film to be cut is placed on the conveyor belt, and the conveyor belt operates intermittently. When the film is transported by the conveyor belt to the bottom of the cutting component, the telescopic rod drives the sampling plate to press down and automatically cut the film on the conveyor belt. When the film is cut, the force is uniform, the edge is regular, and the cutting efficiency is high.

[0007] Further, a conveyor belt placement groove is provided on the base, and the conveyor belt is installed in the conveyor belt placement groove. Through such a design, the surface of the conveyor belt conveying the film is lower than the upper surface of the base, so that the cutting assembly is easy to operate during installation and operation.

[0008] Furthermore, the conveyor belt is coated with a cutting pad, and the material of the cutting pad is PVC, polyethylene or rubber. Through such a design, the cutting pad is a flexible material and can be coated on the outer surface of the conveyor belt. When the film is placed on the cutting pad, the cutting blade can penetrate the film and cut into the cutting pad when pressed down. This cutting method can completely separate the film sample from the film body to prevent adhesion. The material used in the cutting pad can be repeatedly cut by the cutting blade.

[0009] Furthermore, it also includes a cutting guide assembly, which includes a mounting plate, a slide rail, a slider and a support frame. The mounting plate is provided with two pieces respectively fixed on both sides of the conveyor belt placement groove, the slide rail is fixedly installed on the side of the mounting plate close to the conveyor belt, the slider and the slide rail are slidably assembled, the slider is provided with an assembly groove, the support frame is clamped on the slider through the assembly groove, and the slide rail cooperates with the slider to provide guidance for the up and down movement of the support frame. Through such a design, the support frame is installed in coordination with the sampling plate, and when the sampling plate moves up and down with the telescopic rod, the coordinated sliding of the slide rail and the slider guides the sampling plate, so that the sampling plate can be pressed down smoothly.

[0010] Furthermore, the end of the mounting plate in the horizontal direction is bent toward the conveyor belt placement groove to form a side limit plate, and the bottom of the mounting plate is also protrudingly provided with a bottom limit block, and the slide rail and the slider are provided with four groups. Through such a design, the side limit plate and the bottom limit block provide a limit for the up and down movement of the support frame to prevent the support frame from deviating from the original movement trajectory.

[0011] Furthermore, an abutment boss is provided on one side of the inner side of the support frame body close to the conveyor belt placement groove. Through such a design, the support frame is designed to ensure that the side of the sampling plate provided with a blade has enough space to pass through the support frame, and the abutment boss of the support frame is to ensure that the sampling plate can have a force application point to drive the support frame to move downward.

[0012] Furthermore, the sampling plate protrudes toward the conveyor belt to form a blade mounting platform, and the blade mounting platform divides the sampling plate into a first table surface and a second table surface. The first table surface cooperates with the abutment boss to abut, and the cutting blade is fixedly arranged on the second table surface.

[0013] Furthermore, the cutting blades are enclosed into a rectangle. With such a design, the sampling plate can be pressed down once to complete a cutting, which is convenient and efficient.

[0014] Furthermore, a fastening bolt is provided on the support frame, and the fastening bolt passes through the support frame in the horizontal direction and partially enters the sampling plate. With such a design, the disassembly connection between the sampling plate and the support frame is convenient and fast. When the sampling plate and the support frame need to be installed, the fastening bolt is tightened to pass through the support frame and screwed into the side of the sampling plate. When the sampling plate needs to be removed, the fastening bolt is screwed out, and the sampling plate and the support frame can be separated.

[0015] The beneficial effects of the utility model are as follows: the film to be cut is placed on the conveyor belt, and the conveyor belt runs intermittently. When the film is transported by the conveyor belt to the bottom of the cutting assembly, the telescopic rod drives the sampling plate to press down and automatically cut the film on the conveyor belt. When the film is cut, the force is evenly applied, the edge is regular and the cutting efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0027] like Figures 1 to 9 shown.

[0028] Example 1

[0029] A pneumatic film cutting machine is used for automatically cutting and sampling film-like materials, including a conveying component and a cutting component, wherein the conveying component includes a base 1 and a conveyor belt 2, and the cutting component includes a frame 3, a telescopic rod 4 and a sampling plate 5. The cutting component is mounted above the conveyor belt 2 through the frame 3, one end of the telescopic rod 4 is fixedly connected to the frame 3 and the other end is detachably connected to the sampling plate 5, the telescopic direction of the telescopic rod 4 is perpendicular to the conveying direction of the conveyor belt 2, and a cutting blade 6 is fixed on the surface of the sampling plate 5 opposite to the conveyor belt 2.

[0030] The base 1 is provided with a conveyor belt placement groove 7 , and the conveyor belt 2 is installed in the conveyor belt placement groove 7 .

[0031] The implementation of the above embodiment is as follows:

[0032] The film is placed on the conveyor belt 2, which is an indirect transmission. When the cutting component is cutting, the conveyor belt 2 stops conveying. When the cutting component is finished cutting, the conveyor belt 2 transports the film forward one station for the next cutting.

[0033] When the cutting assembly needs to cut, the telescopic rod 4 is driven to extend by the cylinder, and the sampling plate 5 at the end of the telescopic rod 4 is pressed down with the telescopic rod 4. The cutting blade 6 arranged on the sampling plate 5 is pressed into the film to cut the film. After the cutting is completed, the telescopic rod 4 is driven to retract by the cylinder to lift the sampling plate 5.

[0034] Example 2

[0035] The conveyor belt 2 is coated with a cutting mat 8, and the material of the cutting mat 8 is PVC, polyethylene or rubber.

[0036] The implementation of the above embodiment is as follows:

[0037] There are two implementations of covering the conveyor belt 2 with a film. When the cut film is hard, the film is usually placed directly on the conveying component. However, when the film is made of plastic, the plastic film is light in weight and the plastic will adhere to the cutting blade 6 during cutting, so that the film is lifted up as the cutting blade 6 is lifted. Therefore, when cutting the plastic film, the plastic film can be wrapped around the conveyor belt 2 in a full circle along the conveying direction of the conveyor belt 2, and the two ends of the plastic film are overlapped and fixed, so that the plastic film as a whole has tension, allowing the cutting to proceed smoothly.

[0038] Example 3

[0039] It also includes a cutting guide component, which includes a mounting plate 9, a slide rail 10, a slider 11 and a supporting frame 12. The mounting plate 9 is provided with two pieces respectively fixed on both sides of the conveyor belt mounting groove 7. The slide rail 10 is fixedly installed on the side of the mounting plate 9 close to the conveyor belt 2. The slider 11 is slidably assembled with the slide rail 10. The slider 11 is provided with an assembly groove 13. The supporting frame 12 is clamped on the slider 11 through the assembly groove 13. The slide rail 10 cooperates with the slider 11 to provide guidance for the up and down movement of the supporting frame 12.

[0040] The end of the mounting plate 9 in the horizontal direction is bent toward the conveyor belt placement groove 7 to form a side limit plate 14, and the bottom of the mounting plate 9 is also protrudingly provided with a bottom limit block 15. Four groups of the slide rails 10 and the sliders 11 are provided.

[0041] A contact boss 16 is provided on one side of the inner side of the supporting frame 12 close to the conveyor belt placement groove 7 .

[0042] The sampling plate 5 protrudes toward the conveyor belt 2 to form a blade mounting platform 17, and the blade mounting platform 17 divides the sampling plate 5 into a first table surface 18 and a second table surface 19. The first table surface 18 cooperates with the abutting boss 16 to abut, and the cutting blade 6 is fixedly arranged on the second table surface 19.

[0043] The cutting blades 6 are arranged in a rectangular shape.

[0044] The implementation of the above embodiment is as follows:

[0045] The supporting frame 12 is installed in cooperation with the sampling plate 5. When the sampling plate 5 moves up and down along with the telescopic rod 4, the sliding rail 10 and the slider 11 slide in cooperation to guide the sampling plate 5, so that the sampling plate 5 can be pressed down steadily.

[0046] The detachable design of the sampling plate 5 and the supporting frame 12 is mainly due to different requirements for the sampling specifications of the film, so the sampling plate 5 with different sizes of the bottom cutting blade 6 needs to be replaced. This design makes replacement more convenient.

[0047] Example 4

[0048] The supporting frame 12 is provided with fastening bolts 20 , and the fastening bolts 20 penetrate the supporting frame 12 in a horizontal direction and partially enter the sampling plate 5 .

[0049] The implementation of the above embodiment is as follows:

[0050] The disassembly connection between the sampling plate 5 and the supporting frame 12 is convenient and fast. When the sampling plate 5 and the supporting frame 12 need to be installed, tighten the fastening bolt 20 so that it passes through the supporting frame 12 and is screwed into the side of the sampling plate 5. When the sampling plate 5 needs to be removed, unscrew the fastening bolt 20, and the sampling plate 5 and the supporting frame 12 can be separated.
