Description

Technical Field

[0001] The utility model relates to a punching tool, in particular to a punching tool for an easily tearable bag. Background Art

[0002] For the convenience of tearing, during the production process of food packaging bags, punching holes are made at the sealing positions. However, due to the different materials of the packaging bags, it is still difficult to open some packaging bags with stronger toughness with only one tearing hole. Therefore, different structures of tearing holes need to be set. But the punching positions of the tearing holes need to be accurately positioned according to the different structures of the packaging bags. Therefore, it is necessary to adjust the punching tool according to different packaging bag structures. Summary of the Utility Model

[0003] In order to overcome the above deficiencies, the utility model provides a punching tool for an easily tearable bag, which facilitates the disassembly, installation and adjustment of the punching needle.

[0004] To achieve this purpose, the structure adopted by the utility model is as follows: the punching tool for an easily tearable bag includes a top plate, a movable plate and a bottom plate arranged in sequence from top to bottom. A cylinder is arranged on the top plate, a movable block is arranged on the movable plate, slide rails are arranged on both sides of the movable block, grooves are arranged on the movable plate corresponding to the positions of the slide rails, and the slide rails are matched with the grooves to connect the movable block with the movable plate. A locking bolt is arranged on the side of the movable plate to position the movable block. A needle hole is formed between the movable plate and the movable block. The punching needle is connected to the bottom of the piston rod of the cylinder, and a material passing groove is formed between the movable plate and the bottom plate.

[0005] The punching needle is connected to the piston rod of the cylinder through a slider. A chute is arranged at the bottom of the piston rod of the cylinder, the slider is inserted into the chute, and a locking bolt is arranged on the side of the piston rod of the cylinder to fix the slider.

[0006] The top plate and the movable plate are connected to each other through a connecting block, and a structural hole is arranged on the connecting block.

[0007] The beneficial effects are as follows: the structure of the utility model is designed reasonably and ingeniously. The slider and the piston rod of the cylinder can be quickly disassembled and installed, and the movable block is detachable. When replacing the punching needle, only need to remove the movable block and the slider from the casing, which is convenient and fast. At the same time, the slider can realize the adjustment of the position of the punching needle. Brief Description of the Drawings

[0008] The utility model will be described by way of examples and with reference to the accompanying drawings, where:

[0009] Figure 1 is the three-dimensional structure diagram of the utility model;

[0010] Figure 2 is the side view of the utility model;

[0011] Figure 3 is the front view of the utility model. Detailed implementation manners

[0012] The present utility model will be further described in detail below with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only showing the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0013] In the description of the utility model, it should be noted that the orientation or positional relationship indicated by terms such as "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0014] In the description of the utility model, it should be noted that unless otherwise clearly specified and defined, terms such as "installation", "provided with", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements; the fixed connection can be welding or bonding. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0015] As Figures 1 - 3 shown, the punching die for an easily tearable bag, the punching die for an easily tearable bag includes a top plate 1, a movable plate 2 and a bottom plate 3 which are arranged in sequence from top to bottom. A cylinder 4 is arranged on the top plate 1, a movable block 5 is arranged on the movable plate 2, sliding rails are arranged on both sides of the movable block 5, grooves are arranged on the movable plate corresponding to the positions of the sliding rails, and the sliding rails are matched with the grooves to connect the movable block 5 with the movable plate 2. A locking bolt is arranged on the side surface of the movable plate 2 to position the movable block 5. A needle hole is formed between the movable plate and the movable block. The punching needle is connected to the bottom of the piston rod 6 of the cylinder. A material passing groove is formed between the movable plate and the bottom plate. When the punching needle 7 is loaded and unloaded, only by separating the movable block 5 from the movable plate 2, the punching needle 7 can be easily removed from the groove of the movable plate 2. The punching needle 7 can be provided with punching needles of different structures according to needs, such as a single tear hole structure, a single tear line structure or a combination of a tear hole and a tear line. The diameter of the needle hole is larger than that of the piston rod 6 of the cylinder, which can ensure the penetration depth of the punching needle 7.

[0016] The punching needle 7 is connected to the piston rod 6 of the cylinder through a slider 8. A chute is provided at the bottom of the piston rod 6 of the cylinder, and the slider 8 is inserted into the chute. A locking bolt is provided on the side of the piston rod 6 of the cylinder to fix the slider. When it is necessary to replace the punching needle 7 with a different structure, the locking bolt is loosened to separate the slider 8 from the piston rod 6 of the cylinder. At the same time, since the slider 8 can move back and forth in the chute, the front and rear positions of the punching needle 7 can be adjusted to accurately control the punching position of the easy-tear bag and ensure smoother tearing of the tearing hole on the easy-tear bag.

[0017] The top plate 1 and the movable plate 2 are connected to each other through a connecting block, and a structural hole is provided on the connecting block. The structural hole reduces the weight of the overall mold on the one hand and strengthens the connection structure on the other hand.

[0018] The structure of the utility model is designed reasonably and ingeniously. The slider and the piston rod of the cylinder can be quickly disassembled and assembled, and the movable block is detachable. When replacing the punching needle, only the movable block and the slider need to be removed from the casing, which is convenient and fast. At the same time, the slider can adjust the position of the punching needle.

[0019] Based on the revelation of the present utility model, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
