Description

Technical Field

[0001] This utility model relates to the field of polyethylene blown film processing technology, specifically a polyethylene blown film punching device. Background Technology

[0002] Polyethylene blown film is generally milky white, translucent, odorless, tasteless, and non-toxic. It possesses good flexibility, a soft touch, and can be easily bent and folded without breaking. It also exhibits excellent chemical stability: it is resistant to acids, alkalis, and salts, and is not easily altered by pesticides and fertilizers. It has good resistance to most household and industrial chemicals. Therefore, it is widely used in food, clothing, garbage bags, vest bags, and other civilian and industrial packaging. In agriculture, it can be used as greenhouse film and mulch film, offering advantages such as good light transmittance and safety for crops.

[0003] When drilling holes in thin films, a set of regularly arranged cutting tools is typically used. However, existing devices may not be able to achieve this well for holes with special shapes or complex drilling patterns, thus limiting the application range and product innovation of thin films.

[0004] To address this problem, the present invention provides a polyethylene blown film perforation device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a polyethylene blown film perforation device, which solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a polyethylene blown film punching device, comprising a base, a punching assembly on the top of the base, and an auxiliary assembly on the outer side of the base; the punching assembly includes a mounting block, a horizontal cylinder fixedly mounted on the top of the mounting block, an assembly plate fixedly connected to the movable end of the horizontal cylinder, a long rod fixedly connected to one side of the assembly plate, a vertical cylinder fixedly mounted on the top of one of the long rods, a downward pressure cylinder fixedly connected to the movable end of the vertical cylinder, an annular blade fixedly connected to the bottom of the downward pressure cylinder, a material discharge cylinder fixedly connected inside the other long rod, and a reinforcing recess fixedly connected to the top of the mounting block.

[0007] Furthermore, casters are fixedly installed on the bottom of the mounting block, and a nut block is fixedly connected to the bottom of the mounting block.

[0008] The above technical solution is used to support the mounting block and enable it to move.

[0009] Furthermore, a protective plate is fixedly connected to the top of the base, and a lead screw is rotatably connected between the two protective plates. The lead screw is internally threadedly connected to the nut block.

[0010] The above technical solution is used to cause the nut block to move.

[0011] Furthermore, a limiting rod is fixedly connected between the two guard plates. The limiting rod passes through the nut block and is slidably connected to it. The drilling assembly also includes a first servo motor, the output shaft of which is fixedly connected to one end of the lead screw.

[0012] The above technical solution is used to limit the nut block and reduce the pressure on the lead screw.

[0013] Furthermore, the auxiliary component includes a main rod, and a parallel roller is rotatably connected between the two main rods.

[0014] The above technical solution is used to ensure that the film to be punched is in a horizontal state.

[0015] Furthermore, the auxiliary component also includes a first mounting rod, with a feeding shaft rotatably connected between the two first mounting rods; the auxiliary component also includes a second mounting rod, with a take-up shaft rotatably connected between the two second mounting rods; and the auxiliary component also includes a second servo motor, with the output shaft of the second servo motor fixedly connected to one end of the take-up shaft.

[0016] By adopting the above technical solution, the user can continuously move the film by pulling it.

[0017] Beneficial effects

[0018] This invention provides a device for punching holes in polyethylene blown film. Compared with the prior art, it has the following advantages:

[0019] 1. The polyethylene blown film punching device has a feeding shaft for placing the film to be processed. By starting the second servo motor, the winding shaft is driven to rotate, and the winding shaft can then pull the film to move. Through the cooperation of two sets of main rods and parallel rotating rollers, the film at this point can be kept in a tensile and horizontal state, which facilitates the subsequent punching operation.

[0020] 2. This polyethylene blown film punching device, by starting the first servo motor, drives the lead screw to rotate. Under the restriction of two limit rods, the nut block causes the lead screw to move linearly along the lead screw. The nut block then drives the installation block casters to move. The casters can support the installation block, and the limit rods can also share the pressure of the lead screw. The installation block also drives the horizontal cylinder to move, and the horizontal cylinder can also drive the assembly plate and long rod to move. Thus, the punching position of the annular blade and the material discharge cylinder can be flexibly controlled at any point in the plane to change the punching position, thereby realizing a relatively complex punching pattern. By starting the vertical cylinder, the lower pressure cylinder and the annular blade are pushed down. With the support of the material discharge cylinder at the punching position, the film can be punched. The cut film residue will slide down through the material discharge cylinder.

The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0028] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] Reference Figures 1 to 4This application provides a polyethylene blown film punching device, including a base 1, a punching assembly 2 on the top of the base 1, and an auxiliary assembly 3 on the outer side of the base 1. The punching assembly 2 includes a mounting block 21, a horizontal cylinder 22 fixedly mounted on the top of the mounting block 21, an assembly plate 23 fixedly connected to the movable end of the horizontal cylinder 22, a long rod 24 fixedly connected to one side of the assembly plate 23, a vertical cylinder 214 fixedly mounted on the top of one of the long rods 24, a lower pressure cylinder 25 fixedly connected to the movable end of the vertical cylinder 214, an annular blade 215 fixedly connected to the bottom of the lower pressure cylinder 25, a material discharge cylinder 26 fixedly connected inside the other long rod 24, a reinforcing recess 27 fixedly connected to the top of the mounting block 21, a caster 28 fixedly mounted on the bottom of the mounting block 21, and a nut block 29 fixedly connected to the bottom of the mounting block 21. A protective plate 210 is fixedly connected to the top of the base 1. A lead screw 211 is rotatably connected between the two protective plates 210, and the lead screw 211 is internally threaded to the nut block 29. A limit rod 212 is fixedly connected between the two protective plates 210. The limit rod 212 passes through the nut block 29 and is slidably connected to it. The drilling assembly 2 also includes a first servo motor 213, and the output shaft of the first servo motor 213 is fixedly connected to one end of the lead screw 211.

[0030] In practical implementation: By starting the first servo motor 213, the lead screw 211 is driven to rotate. Under the constraint of the two limit rods 212, the nut block 29 will be caused by the lead screw 211 to move linearly along the lead screw 211. The nut block 29 will then drive the caster 28 of the mounting block 21 to move. The caster 28 can support the mounting block 21, and the limit rods 212 can also share the pressure of the lead screw 211. The mounting block 21 will then drive the horizontal cylinder 22 to move, and the horizontal cylinder 22 can also drive... The assembly plate 23 and the long rod 24 move, thereby flexibly controlling the annular blade 215 and the material discharge cylinder 26 to change the punching position at any point in the plane, thus realizing a more complex punching pattern. By activating the vertical cylinder 214, the pressure cylinder 25 and the annular blade 215 are pushed down and, with the material discharge cylinder 26 supporting the punching position, the film can be punched. The cut film residue will slide down through the material discharge cylinder 26. The reinforcing concave block 27 is used to strengthen the fixation of the horizontal cylinder 22.

[0031] Reference Figures 1 to 4 In one aspect of this embodiment, the auxiliary component 3 includes a main rod 31, with a parallel roller 32 rotatably connected between two main rods 31. The auxiliary component 3 also includes a first mounting rod 33, with a feeding shaft 34 rotatably connected between two first mounting rods 33. The auxiliary component 3 further includes a second mounting rod 35, with a take-up shaft 36 rotatably connected between two second mounting rods 35. The auxiliary component 3 also includes a second servo motor 37, with the output shaft of the second servo motor 37 fixedly connected to one end of the take-up shaft 36.

[0032] In practice: the feeding shaft 34 is used to place the film to be processed. By starting the second servo motor 37, the winding shaft 36 is driven to rotate. The winding shaft 36 can then pull the film to move. Through the cooperation of the two sets of main rods 31 and parallel rollers 32, the film at this point can be kept in a tensile and horizontal state, which facilitates the subsequent punching operation.

[0033] All electrical devices in this plan are powered by an external power source.

[0034] Working principle: The function of the feeding shaft 34 is to hold the film to be processed. When the second servo motor 37 is started, it drives the take-up shaft 36 to rotate, and the take-up shaft 36 can pull the film forward. During this process, the two sets of main rods 31 and the parallel rollers 32 cooperate with each other to keep the film in a taut and horizontal state, creating favorable conditions for the subsequent perforation operation;

[0035] After the first servo motor 213 is started, it will drive the lead screw 211 to rotate. Because the nut block 29 is constrained by the two limit rods 212, the rotation of the lead screw 211 will cause the nut block 29 to move linearly along the lead screw 211. As the nut block 29 moves, it will also drive the mounting block 21 and the caster 28 to move together. The caster 28 can support the mounting block 21, while the limit rods 212 can also share the pressure borne by the lead screw 211.

[0036] The movement of mounting block 21 will drive the horizontal cylinder 22 to move, and the horizontal cylinder 22 can in turn drive the assembly plate 23 and the long rod 24 to move. Through this linkage, the annular blade 215 and the material discharge cylinder 26 can be flexibly controlled to change the drilling position at any point in the plane, thereby realizing more complex drilling patterns;

[0037] When the vertical cylinder 214 is activated, it pushes the pressure cylinder 25 and the annular blade 215 downwards. At this time, the feed tube 26 supports the punching position, allowing the annular blade 215 to punch the film. The cut film residue slides down through the feed tube 26.

[0038] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
