This utility model discloses a plastic film perforation machine, including a frame, an unwinding section, a perforation section, and a rewinding section. One side of the frame is the operating side, and the other side is the transmission side. The unwinding section includes a roller mounted on the frame, on which a roll of plastic film is wound. The roller rotates to unwind the roll. The perforation section is mounted on the frame and close to the unwinding section. The perforation section includes a piercing mechanism for piercing and perforating the plastic film as it passes. The rewinding section is located on the side of the perforation section away from the unwinding section and is used to rewind the perforated plastic film back into a roll. A power unit drives the unwinding and rewinding sections in a cyclical motion, ensuring that the plastic film is taut when passing through the perforation section. This utility model unwinds the film using the unwinding section, rewinds it using the rewinding section, and perforates the roll at predetermined positions using the perforation section. This allows for accurate, efficient, and controllable perforation of the plastic film before placement.

Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery and relates to a machine that can easily punch holes in plastic film. Background Technology

[0002] Mulching is becoming increasingly widespread in agriculture. Mulching can increase soil temperature and retain heat. In cold regions, it can raise the soil temperature (0-5 cm) inside the mulch by 2-4°C and the near-soil air temperature by 4-8°C during winter and spring, equivalent to extending the crop growing season by 20-30 days. In hot summers, it can lower the soil temperature inside the mulch. Mulching also helps retain moisture, conserve fertilizer, suppress weeds, and improve light penetration. In mulched agriculture, puncturing the mulch is a crucial operation. The purpose of puncturing is to facilitate sowing or transplanting, ensure air and light penetration, and prevent seedling suffocation. The primary method is manual puncturing, using specialized tools such as small shovels or bamboo sticks to gently cut or poke holes in the mulch at the desired locations. This method is flexible, allowing for precise control of the puncture location and size, but its efficiency is relatively low. In large-scale planting areas, agricultural machinery such as seeders or transplanters equipped with puncture devices can be used to automatically puncture the mulch during sowing or transplanting. While this puncture technique can greatly improve work efficiency, the puncture quality is poor, the puncture location is difficult to guarantee, and the size of the puncture hole is hard to control.

[0003] Therefore, there is an urgent need in the field of agricultural planting machinery for a specialized machine that can accurately, efficiently, and controllably punch holes in plastic film. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a mulch film punching machine that can accurately, efficiently and controllably punch holes in mulch film.

[0005] According to one aspect of the present invention, a plastic film perforation machine is provided for perforating plastic film, the plastic film perforation machine comprising:

[0006] The frame has an operating side on one side and a transmission side on the other side.

[0007] The unwinding section includes a roller, which is mounted on the frame. A film roll formed by the mulch film is sleeved on the roller, and the roller rotates to unwind the film roll.

[0008] The perforation section is mounted on the frame and close to the unwinding section. The perforation section includes a piercing mechanism for piercing and punching holes in the passing plastic film.

[0009] A winding section is located on the side of the perforated section away from the unwinding section, and the winding section is used to rewind the perforated mulch film into a film roll.

[0010] The power unit is used to drive the unwinding section and the winding section to operate in a cyclical manner, and to keep the mulch film in a taut state when it passes through the perforation section.

[0011] According to one embodiment of the present invention, the frame is fitted with three bearings at each end of the roller joint, and the roller is supported on the frame by the bearings, so that the roller can rotate flexibly.

[0012] According to one embodiment of the present invention, the portion of the unwinding section located on the operating side is provided with a friction damping wheel. The friction damping wheel changes its resistance by adjusting the spring pressure, and the resistance is transmitted to the roll shaft through gears to control the tension of the mulch film during the unwinding process.

[0013] According to one embodiment of the present invention, the portion of the unwinding section located on the transmission side is provided with a fork limiter. The fork limiter slides in contact with the roll shaft. By adjusting the fork bolt, the angle between the fork and the frame is changed, and the roll shaft is moved laterally, so that the lateral position of the mulch film is dynamically adjusted during the unwinding process.

[0014] According to one embodiment of the present invention, the punching part includes a punching shaft, a punching wheel, and a brush roller. The punching shaft is mounted on the frame at both ends via bearings. The punching wheel is mounted on the punching shaft and its position can be adjusted laterally. The brush roller is mounted on the frame at both ends via sliding bearings, and a piercing mechanism is connected to the punching wheel.

[0015] According to one embodiment of the present invention, there are 6-15 perforating wheels, and the wheels are inlaid with 8-20 rows of Φ4-Φ8 perforating needles spaced 5-8 mm apart. The perforating wheels can continuously puncture a 40-80 mm wide perforation area on the mulch film. By adjusting the position interval of the perforating wheels on the perforating shaft, the spacing of the perforation area on the mulch film can be changed.

[0016] According to one embodiment of the present invention, a pressure roller is provided on the punching wheel. The pressure roller is used to press the mulch film into the punching wheel and to puncture and punch holes in the mulch film under the action of the puncturing mechanism.

[0017] According to one embodiment of the present invention, the winding section includes a torsion wheel, which is rotatably mounted on the frame and is connected to the perforating shaft for winding the mulch film.

[0018] According to one embodiment of the present invention, the power unit includes a motor, the motor is connected to the reel via a transmission mechanism, and the reel is connected to the take-up shaft.

[0019] According to one embodiment of the present invention, the power unit further includes a control module, which controls the operation of the motor.

[0020] According to one embodiment of the present invention, the mulch film perforating machine is suitable for mulching requirements of rice, millet, sorghum, vegetables, flowers, medicinal herbs, wheat, and high-density varieties.

[0021] As can be seen from the above technical solution, the advantages and positive effects of this utility model are as follows:

[0022] The mulch film punching machine of this utility model unwinds the film roll through the unwinding section, winds it up through the winding section, and punches holes in the film roll at the set positions through the punching section. Thus, the punching is completed according to the set positions before the mulch film is placed. Therefore, it can accurately, efficiently and controllably punch holes in the mulch film.
