Description

Technical Field

[0001] This utility model relates to the field of sealing machine cutting technology, and in particular to a cutting device for a film sealing machine. Background Technology

[0002] A film sealing machine is a device used to seal packaging films. It can heat-seal or cold-seal film bags containing products, ensuring that the contents of the bag are isolated from the external environment, thus preventing moisture, oxidation, and pollution, and extending the shelf life of the product. The cutting equipment for film sealing machines is usually a special cutting device designed to work with the film sealing machine, mainly used to cut the sealed film.

[0003] Existing technologies, such as the utility model with publication number CN217261166U, disclose a cutting device for a film sealing machine, relating to the technical field of film cutting devices. It includes a housing and a movable frame. A placement groove is provided on one side of the housing, and a cylinder rod is installed within the groove. The lower end of the movable frame is installed in the placement groove and is connected to one end of the cylinder rod via a transmission mechanism. The upper end of the movable frame is installed above the housing. Several electric telescopic rods are provided on the lower surface of the upper end of the movable frame. A mounting plate is provided at the lower end of each electric telescopic rod. Limiting rods and telescopic rollers are provided on both sides of the lower surface of the mounting plate. Springs are wound around the telescopic rollers. A fixing frame is provided on the upper surface of the mounting plate, and a transmission mechanism is provided on the side of the fixing frame. An elongated hole is provided in the center of the mounting plate, and a moving rod is located in the elongated hole. The upper end of the moving rod is connected to the transmission mechanism, and a cutting blade is provided at the lower end of the moving rod. The cutting blade cuts the film material. This device is highly practical and solves the problem that current cutting processes primarily rely on manual cutting, which cannot guarantee the flatness of the film material, affecting the product's appearance.

[0004] In daily work, it has been found that when the existing film sealing machine cutting equipment is used, the film can be clamped and then cut. However, after clamping the film, wrinkles will appear between the two clamping parts, and the film cannot be flattened. This results in uneven cutting, which affects the appearance. This leads to the problem of uneven cutting and poor appearance of the existing film sealing machine cutting equipment. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as uneven cutting that affects aesthetics, and to propose a cutting device for a film sealing machine.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a cutting device for a film sealing machine, comprising a worktable and an auxiliary device. A support is provided on the surface of the worktable, and a cylinder is mounted above the support. A cutting scissor is mounted on the output end of the cylinder. The auxiliary device is disposed on the surface of the support and includes two cylinders. The two cylinders are fixedly connected to the surface of the support. A movable plate is fixedly connected to the output end of each cylinder, and a through hole is provided in the movable plate for the cutting scissors to pass through. Two upper clamping plates are slidably connected to the inner wall of the movable plate. Two bidirectional cylinders are fixedly connected to the upper surface of the movable plate. The output ends of the bidirectional cylinders are fixedly connected to the surfaces of the two upper clamping plates respectively. The surface of the worktable is provided with a cooperating component. Through the above components, before cutting, cylinder two can drive the movable plate and the upper clamping plates to move downward. The upper clamping plates cooperate with the cooperating component to clamp the film. Then, the bidirectional cylinder operates, and the upper clamping plates and the cooperating component can pull the film to both sides a certain distance, thereby flattening the cutting area. Then, cylinder one cooperates with the cutting scissors to perform the cutting operation.

[0007] Preferably, the mating assembly includes two lower clamping plates, which are slidably connected to the inner wall of the worktable. Each lower clamping plate has two circular holes on its surface. Two insertion posts are fixedly connected to the surface of the upper clamping plate, and these insertion posts are inserted into the inner walls of the circular holes. Through these components, when the upper clamping plate mates with the mating assembly, after moving to a certain position, the upper clamping plate, in conjunction with the lower clamping plate, clamps the film. Subsequently, the insertion posts are inserted into the circular holes on the surface of the lower clamping plate. When the upper clamping plate moves, it can drive the lower clamping plate to move, thereby allowing the upper and lower clamping plates to pull and flatten the film.

[0008] Preferably, the upper clamping plate extends from the movable plate to a certain height, and the lower clamping plate extends from the worktable to a certain height. Through the above components, both the upper and lower clamping plates extend to a certain height, which facilitates better clamping and pulling operations on the film.

[0009] Preferably, the inner wall of the workbench is fixedly connected to two guide columns, and the lower clamping plate is slidably connected to the surface of the guide columns. Through the above components, the guide columns can guide the lower clamping plate and improve stability.

[0010] Preferably, a spring is fixedly connected to the side of the lower clamping plate corresponding to the inner wall of the worktable. The two ends of the spring are fixedly connected to the lower clamping plate and the inner wall of the worktable, respectively. Through the above-mentioned components, the spring can control the lower clamping plate to reset, while ensuring the stability of the lower clamping plate after reset.

[0011] Preferably, the surface of the support is provided with a stabilizing device, which includes two fixed rods. The two fixed rods are respectively fixedly connected to the two side surfaces of the support. The surface of the fixed rods is rotatably connected to a rotating arm, and the inner walls of the two rotating arms are rotatably connected to pressure rollers. Through the above components, during the movement of the film, the rotating arms and pressure rollers can press on the film with their own weight, thereby limiting the film and reducing displacement.

[0012] Preferably, a handle is fixedly connected to one side surface of the rotating arm. Through the above-mentioned component, the handle makes it easy to lift the rotating arm and the pressure roller, thereby improving ease of use.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting an auxiliary device, the film can be pulled to both sides when pressing the film, so that the film cutting part is flat. This can effectively eliminate unevenness such as wrinkles and curls that may exist in the film at the cutting part. During cutting, it can ensure that the cutting edge is neat and improve the cutting accuracy and quality.

[0015] 2. In this utility model, by setting a stabilizing device, the film can be pressed down, thereby limiting the film and reducing the phenomenon of film displacement. Attached Figure Description

Detailed Implementation

[0023] See also Figures 1-5 This utility model provides a technical solution: a cutting device for a film sealing machine, including a workbench 1 and an auxiliary device 5. A support 2 is provided on the surface of the workbench 1, a cylinder 3 is installed above the support 2, and a cutting scissors 4 is installed at the output end of the cylinder 3. The auxiliary device 5 is provided on the surface of the support 2.

[0024] Specifically, the auxiliary device 5 includes two cylinders 51. The two cylinders 51 are fixedly connected to the surface of the bracket 2. The output end of the cylinders 51 is fixedly connected to a movable plate 52. The movable plate 52 has a through hole for the cutting shears 4 to pass through. The inner wall of the movable plate 52 is slidably connected to two upper clamping plates 54. The upper surface of the movable plate 52 is fixedly connected to two bidirectional cylinders 55. The output ends of the bidirectional cylinders 55 are fixedly connected to the surfaces of the two upper clamping plates 54 respectively. The surface of the worktable 1 is provided with a mating assembly 53.

[0025] In this embodiment: Before cutting, cylinder 2 51 can drive the moving plate 52 and the upper clamping plate 54 to move downward. The upper clamping plate 54 cooperates with the cooperating component 53 to clamp the film. Then, the bidirectional cylinder 55 operates, and the upper clamping plate 54 and the cooperating component 53 can pull the film to both sides of a certain distance, thereby flattening the cutting part. Then, cylinder 1 3 cooperates with the cutting scissors 4 to perform the cutting operation.

[0026] Specifically, the mating component 53 includes a lower clamping plate 531, and there are two lower clamping plates 531. The two lower clamping plates 531 are slidably connected to the inner wall of the worktable 1. Two round holes 532 are opened on the surface of the lower clamping plate 531. Two inserts 535 are fixedly connected to the surface of the upper clamping plate 54. The inserts 535 are inserted into the inner wall of the round holes 532.

[0027] In this embodiment: when the upper clamping plate 54 cooperates with the mating component 53, after the upper clamping plate 54 moves to a certain position, the upper clamping plate 54 cooperates with the lower clamping plate 531 to clamp the film. Then the insert post 535 is inserted into the round hole 532 on the surface of the lower clamping plate 531. When the upper clamping plate 54 moves, it can drive the lower clamping plate 531 to move, so that the upper clamping plate 54 cooperates with the lower clamping plate 531 to pull and flatten the film.

[0028] Specifically, the upper clamping plate 54 extends from the moving plate 52 to a certain height, and the lower clamping plate 531 extends from the worktable 1 to a certain height. Both the upper clamping plate 54 and the lower clamping plate 531 extend to a certain height, which facilitates better clamping and pulling of the film.

[0029] Specifically, the inner wall of the workbench 1 is fixedly connected to two guide posts 533, and the lower clamping plate 531 is slidably connected to the surface of the guide posts 533.

[0030] In this embodiment, the guide post 533 can guide the lower clamping plate 531 and improve its stability.

[0031] Specifically, a spring 534 is fixedly connected to the side of the lower clamping plate 531 corresponding to the inner wall of the worktable 1. The two ends of the spring 534 are fixedly connected to the lower clamping plate 531 and the inner wall of the worktable 1 respectively. The spring 534 can control the lower clamping plate 531 to reset, and at the same time ensure the stability of the lower clamping plate 531 after reset.

[0032] Specifically, the surface of the support 2 is provided with a stabilizing device 6, which includes a fixing rod 61. There are two fixing rods 61, which are fixedly connected to the two side surfaces of the support 2 respectively. The surface of the fixing rod 61 is rotatably connected to a rotating arm 62, and the inner wall of the two rotating arms 62 is rotatably connected to a pressure roller 63.

[0033] In this embodiment: during the movement of the film, the rotating arm 62 and the pressure roller 63 can press on the film with their own weight, which can limit the film and reduce the deviation.

[0034] Specifically, a handle 64 is fixedly connected to one side surface of the rotating arm 62. The handle 64 makes it easy to lift the rotating arm 62 and the pressure roller 63, thus improving ease of use.

[0035] Working principle: During cutting, firstly, cylinder 2 51 is opened, which pushes the moving plate 52 and the upper clamping plate 54 to move closer to the lower clamping plate 531. After moving to a certain position, the upper clamping plate 54 and the lower clamping plate 531 clamp the film. The inserts 535 on the surface of the upper clamping plate 54 are inserted into the round holes 532 on the surface of the lower clamping plate 531. Then, the bidirectional cylinder 55 is opened, which pushes the two upper clamping plates 54 to move. The upper clamping plates 54, together with the inserts 535, move the lower clamping plate 531 together. Then, the two sets of upper clamping plates 54 and lower clamping plates 531 pull the film to both sides, straightening the film at the cutting point. The cylinder 3 is opened, and the cylinder 3 drives the cutting scissors 4 to move. The cutting scissors 4 pass through the through hole on the surface of the moving plate 52, thereby cutting the film. When the film is transported and moved, the arm 62 and the pressure roller 63 can be rotated in the fixed rod 61, so that the pressure roller 63 presses on the film. The pressure roller 63, together with the weight of the rotating arm 62, can press down on the film, thereby ensuring the stability of the film during movement, and then it can be used.
