Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically a multifunctional black and white mulch film production cutting device. Background Technology

[0002] The multi-functional black and white mulch film cutting device is a specialized piece of equipment for cutting black and white mulch film. It typically consists of the following components: a cutting system, a conveying system, a control system, and auxiliary equipment.

[0003] According to the utility model patent with authorization announcement number CN213859489U, a cutting device for producing mulch film is disclosed, comprising: a crossbeam, mounted above the mulch film; two supports, each connected to the lateral sides of the mulch film to support the crossbeam, wherein at least one end of the crossbeam is threadedly engaged with the supports to form a helical pair; a cutting mechanism disposed on the crossbeam; and a drive source capable of driving the crossbeam to rotate. As the crossbeam rotates, it moves along its length under the action of the helical pair, thereby causing the cutting mechanism to rotate and move closer to or away from the mulch film. During this process, the movement trajectory of the cutting mechanism is a reversible curve.

[0004] However, the multi-functional black and white mulch film production and cutting device is inconvenient to disassemble the rollers during use, and the impact force of the cutting blade can easily damage the cylinder during use. Utility Model Content

[0005] The purpose of this utility model is to provide a multifunctional black and white mulch film production and cutting device, which solves the problems that it is inconvenient to disassemble the rollers during use, and that the impact force of the cutting blade can easily damage the cylinder during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional black and white mulch film production and cutting device, comprising a base, a bracket fixedly connected to the left side of the base, a connecting frame contacting the right end of the base, a motor fixedly mounted on the bracket, the output end of the motor rotatably connected to the bracket, a rotating shaft connected inside the connecting frame via bearings, a turntable contacting the sides of the bracket and the connecting frame that are close to each other, a square block fixedly connected to the sides of the turntables that are close to each other, rollers contacting the sides of the turntables that are close to each other, the rollers slidingly connected to the square blocks, a threaded rod connected inside the connecting frame via bearings, the threaded rod being threadedly connected to the base, fixed plates fixedly connected to both ends of the base, a cylinder fixedly mounted on the upper end of the fixed plate, a cutter fixedly connected to the output end of the cylinder, and a buffer mechanism provided on the base.

[0007] Preferably, one of the turntables is fixedly connected to the output end of the motor, and the other turntable is in contact with the rotating shaft. Through the design of the turntables, the rollers can be driven to rotate.

[0008] Preferably, a knob is fixedly connected to the end of the threaded rod away from the base. The knob contacts the base, and the design of the knob allows the threaded rod to be rotated easily.

[0009] Preferably, a guide rod is fixedly connected to the side of the connecting frame near the base, and the guide rod is slidably connected to the base. The design of the guide rod can guide the connecting frame.

[0010] Preferably, the buffer mechanism includes a slide rod, which is slidably connected inside the base. A pressure plate is fixedly connected to the upper end of the slide rod, and a damping block is fixedly connected to the lower end of the slide rod. The damping block is slidably connected to the base. A limit ring is fixedly connected to the upper end of the base, and the limit ring is slidably connected to the slide rod. A spring is provided inside the base, and an air hole is provided on the base. By activating the cylinder, the output end of the cylinder drives the cutter to cut, so that the cutter contacts the pressure plate during cutting. The pressure plate drives the slide rod to slide within the limit ring, causing the slide rod to move the damping block. The damping block forces the gas in the base through the air hole to squeeze the base and compress the spring, effectively buffering the cutter and protecting the cylinder.

[0011] Preferably, one end of the spring contacts the base, and the other end of the spring contacts the slide bar. The design of the spring can increase the friction of the damping block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up components such as a connecting frame, a square block, and a threaded rod, allows the connecting frame to move the square block by rotating the threaded rod, causing the square block to slide out of the roller and thus the roller can be removed. This solves the problem of inconvenient roller disassembly during the use of the multi-functional black and white mulch film production and cutting device.

[0014] 2. This utility model, by incorporating components such as a pressure plate, damping block, and spring, allows the cutting blade to contact the pressure plate during cutting. This causes the damping block to slide within the base and compress the spring, effectively buffering the pressure plate and thus the cutting blade. This solves the problem that the impact force of the cutting blade can easily damage the cylinder during the use of the multi-functional black and white mulch film production cutting device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 A multifunctional black and white mulch film production and cutting device includes a base 1, a bracket 2 fixedly connected to the left side of the base 1, a connecting frame 21 contacting the right end of the base 1, a motor 3 fixedly mounted on the bracket 2, the output end of the motor 3 being rotatably connected to the bracket 2, a rotating shaft 31 connected inside the connecting frame 21 via a bearing, and turntables 32 contacting each other on the sides of the bracket 2 and the connecting frame 21, one of the turntables 32 being fixedly connected to the output end of the motor 3, and the other turntable 32 contacting the rotating shaft 31. Through the design of the turntables 32, rollers 34 can be driven to rotate.

[0023] Please see Figure 2-5A square block 33 is fixedly connected to one side of the turntable 32. Rollers 34 are in contact with the other side of the turntable 32. The rollers 34 and the square blocks 33 are slidably connected. A threaded rod 35 is connected to the inside of the connecting frame 21 through a bearing. The threaded rod 35 is threadedly connected to the base 1. A knob 36 is fixedly connected to the end of the threaded rod 35 away from the base 1. The knob 36 is in contact with the base 1. The design of the knob 36 allows for easy rotation of the threaded rod 35. A guide rod 37 is fixedly connected to the side of the connecting frame 21 near the base 1. The guide rod 37 is slidably connected to the base 1. The design of the guide rod 37 allows for guiding the connecting frame 21. Fixed plates 4 are fixedly connected to both ends of the base 1. A cylinder 41 is fixedly installed on the upper end of the fixed plate 4. A cutter 42 is fixedly connected to the output end of the cylinder 41. A buffer mechanism 5 is provided on the base 1.

[0024] Please see Figure 2-5 The buffer mechanism 5 includes a slide rod 51, which is slidably connected inside the base 1. A pressure plate 52 is fixedly connected to the upper end of the slide rod 51, and a damping block 53 is fixedly connected to the lower end of the slide rod 51. The damping block 53 is slidably connected to the base 1. A limit ring 54 is fixedly connected to the upper end of the base 1, and the limit ring 54 is slidably connected to the slide rod 51. A spring 55 is installed inside the base 1, with one end of the spring 55 contacting the base 1 and the other end contacting the slide rod 51. The design of the spring 55 increases the damping force. The friction of the damping block 53 and the air hole 56 on the base 1 are used to generate air. By starting the cylinder 41, the output end of the cylinder 41 drives the cutter 42 to cut. When the cutter 42 cuts, it contacts the pressure plate 52, which causes the pressure plate 52 to drive the slide rod 51 to slide within the limit ring 54. The slide rod 51 drives the damping block 53 to move, and the damping block 53 forces the gas in the base 1 out of the base 1 through the air hole 56 and squeezes the spring 55. This can effectively buffer the cutter 42 and effectively protect the cylinder 41.

[0025] The specific implementation process of this utility model is as follows: When in use, rotate the knob 36 to drive the threaded rod 35 to rotate, so that the threaded rod 35 and the base 1 have a threaded movement, thereby moving the threaded rod 35 in the base 1, which can drive the connecting frame 21 to move, thereby driving the connecting frame 21 to move the turntable 32, which in turn drives the square block 33 to move, so that the square block 33 slides out of the roller 34, thereby releasing the limit on the roller 34, and the roller 34 can be disassembled;

[0026] By activating cylinder 41, the output end of cylinder 41 drives the cutter 42 to cut, so that the cutter 42 contacts the pressure plate 52 during cutting, and the pressure plate 52 drives the slide rod 51 to slide within the limiting ring 54, so that the slide rod 51 drives the damping block 53 to move, so that the damping block 53 squeezes the gas in the base 1 through the air hole 56 and squeezes the spring 55, which can effectively buffer the cutter 42 and effectively protect the cylinder 41.
