Description

Technical Field

[0001] The utility model relates to the technical field of ground film processing, in particular to a cutting machine for producing plastic agricultural films. Background Art

[0002] Agricultural film, also known as film plastic or ground film (also called agricultural mulch), is primarily made of polyethylene. It's used to cover farmland, raising ground temperature, maintaining soil moisture, promoting seed germination and rapid seedling growth, and suppressing weed growth.

[0003] The application number in the existing public technology is: CN201921084090.1 A cutting device for ground film production, which uses a water pump to spray the coolant in the liquid storage tank onto the cutting blade on the cutting machine to cool the cutting blade. This can ensure that the cutting machine can continue to work normally for a long time to the greatest extent, avoid the additional impact of the overheated cutting blade on the cutting machine on the ground film, and ensure the regularity of the ground film after cutting.

[0004] However, the above patent still has certain shortcomings when in use: although it can spray coolant through the spray head to cool the blade of the cutting machine, as the internal threaded sleeve moves, the distance between the blade and the spray head will increase, which will cause the spray liquid to be unable to cool the blade normally. Moreover, there is a lack of fixing measures when placing the ground film, which is easy to cause the ground film to be dislocated due to the squeezing of the blade and the impact of the spray liquid, thereby affecting the overall cutting operation, resulting in a decrease in the quality of ground film cutting, and the overall use effect is not very good.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0031] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. Figure 1-4 As shown, according to the embodiment of the present invention, the cutting machine for producing plastic agricultural film includes a cutting table 1 and a support leg 19. Support arms 6 are symmetrically welded to the middle positions on both sides of the top of the cutting table 1. A support plate 9 is welded to the top of the support arm 6. A slide bar 8 is installed at the middle position of the surface of the support arm 6. A mounting seat 12 is sleeved on the outer periphery of the slide bar 8. A cylinder 16 is installed between the top of the mounting seat 12 and the support plate 9. Mounting brackets 17 are symmetrically welded to the two sides of the bottom of the mounting seat 12. There are two groups of mounting brackets 17. Connectors 7 and motors 18 are installed on the surfaces of the two groups of mounting brackets 17 respectively. The positions between the mounting brackets 17 are rotated. A drive shaft 15 is connected, one end of the drive shaft 15 passes through the surface of a mounting bracket 17 on one side and is connected to a motor 18, and the other end of the drive shaft 15 is sleeved on the surface of the connector 7. A cooling chamber 23 is provided inside the drive shaft 15 and the connector 7. A partition 21 is welded on one side of the cooling chamber 23, and a discharge pipe 20 is rotatably connected to the middle position of the partition 21. Several groups of flow holes 22 are provided on the surface of the partition 21. Pipes are symmetrically installed on one side of the top of the connector 7, and the pipes are respectively connected to the circulation pump 10 and the cooling box 11. The circulation pump 10 and the cooling box 11 are both located at the top of the support plate 9.

[0032] In one embodiment, a fixing seat 3 is symmetrically welded on the top surface of the cutting table 1 between the support arms 6, and a pressure plate 4 is slidably connected to the internal position of the fixing seat 3. An adjusting screw 5 is rotatably connected to the middle position of the top of the pressure plate 4, and one end of the adjusting screw 5 passes through one side of the fixing seat 3. Several groups of negative pressure holes 2 are evenly opened in the middle position of the top surface of the cutting table 1. The negative pressure holes 2 are connected to the negative pressure pump 14 through a pipe. The negative pressure pump 14 is located on the top surface of the support plate 9. The negative pressure pump 14 and the circulation pump 10 are both common structures, so they will not be described in detail.

[0033] In one embodiment, a plurality of cutting blades 13 are mounted around the surface of the driving shaft 15 . The cutting blades 13 are basic components of the cutting machine, and therefore will not be described in detail.

[0034] In one embodiment, legs 19 are symmetrically installed on both sides of the bottom of the cutting table 1. The legs 19 can support the entire device to enhance the overall stability in use.

[0035] In one embodiment, the cooling box 11 is composed of a water tank and a refrigerator. The refrigerator is provided to re-cool the coolant inside the water tank. Due to the variety of refrigerator types and mature application technologies, no further details will be given.

[0036] In one embodiment, a rubber pad is provided on the bottom surface of the pressing plate 4. The rubber pad is provided to reduce the damage to the agricultural film caused by the pressing plate 4 when squeezing the agricultural film, thereby ensuring the integrity of the agricultural film.

[0037] In one embodiment, a controller is provided on the surface of the cutting table 1. The controller is provided to control the equipment inside the device. Since there are various types of controllers and the application technology is mature, and people can easily purchase suitable products on the market and implement control through programming, we will not go into details.

[0038] In one embodiment, the size of the fixing seat 3 and the distribution size of the negative pressure holes 2 are both larger than the size of the plastic agricultural film. The sizes of the fixing seat 3 and the negative pressure holes 2 are designed to ensure that they can fully act on the plastic agricultural film to ensure that subsequent cutting operations can be carried out smoothly.

[0039] Working principle: In actual use, personnel can place the two ends of the plastic agricultural film into the internal position of the fixing seat 3 respectively, and then push the pressing plate 4 downward by adjusting the rotation of the screw 5, so that the pressing plate 4 can be firmly against the surface of the agricultural film. Then, the operation of the negative pressure pump 14 can be used to extract the gas under the agricultural film through the negative pressure hole 2, thereby realizing the negative pressure adsorption operation of the agricultural film. The combination of the pressing plate 4 and the negative pressure hole 2 can improve the fixing effect of the agricultural film, avoid the misalignment problem during subsequent cutting, ensure the cutting accuracy and cutting effect, and then After the fixation is completed, the operation of the cylinder 16 can drive the mounting seat 12 to move downward. At this time, the cutting blade 13 below the mounting seat 12 will contact the agricultural film, thereby realizing the cutting operation of the agricultural film. Then the cylinder 16 returns to its position to drive the mounting seat 12 to move up again. At this time, the operation of the motor 18 can drive the drive shaft 15 to rotate. The rotation of the drive shaft 15 can replace the positions of the cutting blades 13 at different positions on its surface, so that the unused cutting blades 13 can face upward, and the used blades can be adjusted to other positions, effectively avoiding long-term Using a set of blades at a time causes the temperature of the blades to rise, which in turn causes the agricultural film to melt during cutting, thereby avoiding interference with the cutting. In addition, when the drive shaft 15 rotates, coolant can be continuously input into the connector 7 through the pipeline. At this time, the coolant can enter the internal position of the drive shaft 15 through the cooling cavity 23. At this time, the coolant can cool the outer surface position of the drive shaft 15, thereby realizing the cooling operation of the cutting blade 13. The used coolant can enter the position at the bottom end of the discharge pipe 20 through the flow hole 22 on the surface of the partition 21. At this time, the coolant can be extracted from the discharge pipe 20 through the suction of the circulation pump 10, so that this part of the coolant after absorbing heat can return to the inside of the cooling box 11, and the re-cooling operation can be achieved through the refrigerator in the cooling box 11, which is convenient for subsequent secondary use. Since the flow of the coolant is realized inside the connector 7 and the drive shaft 15, it will not directly act on the agricultural film, so it can avoid the impact of the coolant on the stability of the agricultural film, effectively ensuring the cutting quality of the agricultural film. The overall device has the advantages of strong cutting stability, small blade cooling interference, and good blade cooling effect.
