Description

Technical Field

[0001] This utility model relates to the field of plastic film preparation equipment technology, specifically to a perforation device for plastic film preparation. Background Technology

[0002] Plastic film preparation refers to the process of processing plastic granules into plastic films, usually using the blow molding method. The blow molding method involves heating plastic granules or powder to melt them, and then blowing the molten plastic into a film using a blow molding machine.

[0003] A blown film machine is a plastic film processing device that heats and melts plastic particles, then blows them into a film. The film, typically blown through a die and air ring, is in a tubular shape and then clamped by a herringbone plate to obtain the finished film.

[0004] The film produced by the blown film machine is generally used for product packaging. In actual packaging, especially for neatly arranged goods, only the four corners need to be sealed; the remaining packaging areas do not need to be sealed. Therefore, to save costs, the film is usually manually perforated after collection. The perforated areas are then cut into waste circular perforated film, which is collected and reused, reducing usage costs. The cut film still maintains the integrity of the packaging. However, manual cutting is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0005] The purpose of this invention is to provide a punching device for plastic film preparation, thereby solving the above-mentioned technical problems.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a perforation device for plastic film preparation, including a blown film machine and a transport frame, including a first perforation component and a collection frame;

[0007] The first punching assembly includes a mounting bracket, an electric push rod, and a circular blade. The mounting bracket is arranged in a U-shape on the transport frame. The electric push rod is arranged on the crossbar of the mounting bracket, with the telescopic rod of the electric push rod pointing downwards and the bottom connected to a circular blade for cutting the film.

[0008] A collection box, located below the mounting frame, is used to collect the discarded circular perforated membrane after cutting.

[0009] As a further technical solution of the above solution, the crossbar of the mounting frame is rotatably disposed between two vertical bars and the surface of the crossbar is threaded. The side wall of the vertical bar is provided with a motor, and the output shaft of the motor passes through the vertical bar and is connected to the crossbar to drive the crossbar to rotate. It also includes multiple mounting blocks, which are screwed onto the crossbar of the mounting frame. Multiple electric push rods are respectively fixedly disposed on multiple mounting blocks and move along the crossbar with the mounting blocks.

[0010] As a further technical solution to the above scheme, multiple electric push rods and circular blades are provided, and the multiple electric push rods are equally spaced along the length direction of the mounting frame crossbar.

[0011] As a further technical solution to the above solution, a second punching assembly is also included. The second punching assembly has the same structure as the first punching assembly. The second punching assembly is set on the transport frame and is arranged parallel to the first punching assembly.

[0012] Compared with the prior art, this utility model has the following advantages and beneficial effects: the device sets the mounting frame on the transport frame, and uses an electric push rod to push the circular blade downward to cut and punch holes in the membrane. The waste membrane after cutting is collected and recycled through the collection frame for reuse, which reduces the cost of use; the electric drive for cutting improves work efficiency.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.

[0018] like Figures 1-3 As shown, a perforation device for plastic film preparation includes a blown film machine and a transport frame 3, including a first perforation assembly 1 and a collection frame 6;

[0019] The first punching assembly 1 includes a mounting frame 11, an electric push rod 12, and a circular blade 13. The mounting frame 11 is arranged in a U-shape on the transport frame 3. The electric push rod 12 is arranged on the crossbar of the mounting frame 11, and the telescopic rod of the electric push rod 12 is set downward and connected to the bottom of the circular blade 13, which is used to cut the film.

[0020] Collection box 6, located below mounting frame 11, is used to collect the discarded circular perforated membrane after cutting.

[0021] When using this device, a first perforation assembly 1 is installed on the transport frame 3. The mounting frame 11 is arranged in a U-shape on the transport frame 3. The transport frame 3 transports the pressed film using rollers. During transport, as the film passes under the mounting frame 11, the electric push rod 12 is activated. The electric push rod 12 drives the circular blade 13 downwards, pressing it against the film to cut circular holes. The waste film cut at these holes falls under gravity and is collected in the collection frame 6. Once a certain amount of waste film has been collected in the collection frame 6, it is removed for reuse. This method saves on film costs while ensuring the strength of the film packaging, and by using an electric method instead of manual cutting, it improves operational efficiency.

[0022] like Figure 2 As shown, in a preferred embodiment, the crossbar of the mounting frame 11 is rotatably disposed between two vertical bars, and the surface of the crossbar is threaded. A motor 4 is mounted on the side wall of each vertical bar, and the output shaft of the motor 4 passes through the vertical bar and connects to the crossbar to drive the crossbar to rotate. The mounting frame 11 also includes multiple mounting blocks 5, which are screwed onto the crossbar of the mounting frame 11. Multiple electric push rods 12 are respectively fixedly disposed on the mounting blocks 5 and move along the crossbar following the mounting blocks 5. In this embodiment, the position of the electric push rods 12 is set to be movable to meet the requirements for adjusting the drilling position. The crossbar of the mounting frame 11 is threaded, and the mounting blocks 5 are screwed onto the crossbar of the mounting frame 11. When the drilling position needs to be adjusted, the motor 4 is started to drive the crossbar to rotate. Since the mounting blocks 5 are screwed onto the crossbar, the movement of the mounting blocks 5 along the length of the crossbar causes the electric push rods 12 on the mounting blocks 5 to move, thereby adjusting the position of the circular blade 13 and adjusting the drilling position of the circular perforated membrane to meet strength requirements.

[0023] like Figure 2 As shown in the preferred embodiment, multiple electric push rods 12 and annular blades 13 are provided, with the multiple electric push rods 12 evenly spaced along the length of the crossbar of the mounting frame 11. In this embodiment, multiple electric push rods 12 are provided, and they are arranged along the length of the crossbar of the mounting frame 11. During the film transport process, the multiple electric push rods 12 push the annular blades 13 downwards, pressing the film and then cutting. In one pressing process, multiple circular holes can be cut simultaneously, which improves the cutting efficiency.

[0024] like Figure 3As shown, in a preferred embodiment, a second punching component 2 is also included. The second punching component 2 has the same structure as the first punching component 1 and is mounted on the transport frame 3, arranged parallel to the first punching component 1. In this embodiment, the second punching component 2 and the first punching component 1 have the same structure, and the second punching component 2 and the first punching component 1 operate simultaneously, cutting and punching the membrane at the same time, thus improving work efficiency.
