Description

Technical Field

[0001] This utility model relates to the field of mulch film production technology, and more specifically to a biodegradable mulch film production feeding device. Background Technology

[0002] Mulching refers to the practice of covering the ground with agricultural plastic film. During the production process of mulching film, a winding roller is used to wind the film into a roll for easy storage and transportation later.

[0003] A search revealed an existing patent (publication number: CN213382919U) that discloses a biodegradable mulch film production feeding device. During use, a rear feeding roller is movably installed at the rear end of the front feeding roller. This roller rotates with the front feeding roller during feeding, conveying the mulch film downwards. Adjustment grooves are provided on the sides of both the front and rear feeding rollers to adjust the position of the mulch film, ensuring a smoother feeding process and preventing wrinkles during winding. A water inlet is fixedly installed in the middle of the left end of the support bracket. Water circulates inside the support bracket, cooling the mulch film and preventing static electricity buildup that could cause it to stick together and be difficult to wind up after winding. However, the inventors discovered the following problems with the existing technology during the development of this utility model: In the above-mentioned biodegradable mulch film production and feeding equipment, when cooling the mulch film during the conveying process, water is circulated inside the support frame to cool the mulch film laid on the surface of the sliding roller at the top of the support frame. In this cooling process, the heat on the surface of the sliding roller needs to be transferred to the support frame first before it can be cooled by the effect of water flow. The overall cooling conduction efficiency is relatively low. On the other hand, the single method of using water flow for heat conduction and cooling has the defect of a single cooling method, and the cooling effect is difficult to achieve the expected result.

[0004] In view of this, the present invention proposes a biodegradable mulch film production feeding device to solve the above-mentioned problems. Utility Model Content

[0006] This utility model provides the following technical solution: a biodegradable mulch film production feeding device, including a base plate, and the upper surface of the base plate is respectively provided with side plates and a winding assembly. There are two side plates, and guide rollers, water cooling assembly and air cooling assembly are respectively provided between the two side plates corresponding to the external mulch film.

[0007] The water-cooling assembly includes a cooling pipe rotatably connected to the inner wall of the side plate, a cooling roller fixedly connected to the middle section of the cooling pipe, a water tank fixedly installed on the surface of the side plate, ventilation and heat dissipation windows reserved on the surface of the water tank, a fan embedded in the top of the water tank with the air outlet facing the inside of the water tank, a pump body fixedly installed at the bottom of the water tank, the liquid inlet of the pump body extending to the bottom of the water tank, a delivery pipe fixedly installed at the liquid outlet of the pump body, the other end of the delivery pipe being connected to one end of the cooling pipe through a rotating pipe joint, the other end of the cooling pipe being fixedly connected to a return water pipe through a rotating pipe joint, and the other end of the return water pipe being connected to the top of the water tank.

[0008] The air-cooling assembly includes a deionizer fan fixedly installed on the surface of the side plate. Two conveyor plates are fixedly installed at the air outlet end of the deionizer fan. The two conveyor plates extend between the two side plates, and a gap is reserved between the two conveyor plates for the external mulch film to pass through. Several air outlet holes are opened on the adjacent side of the two conveyor plates.

[0009] Furthermore, a control panel is fixedly mounted on the surface of the side panel, and the control panel is electrically connected to an external power source via wires.

[0010] Furthermore, the winding assembly includes a winding frame fixedly mounted on the surface of the base plate, a winding shaft rotatably connected to the surface of the winding frame, a winding motor for driving the winding shaft to rotate coaxially fixedly mounted on the surface of the winding frame, and a winding roller sleeved on the surface of the winding shaft.

[0011] As a further description of the above technical solution: through the design of the winding assembly, the winding motor drives the winding shaft to rotate, thereby driving the winding roller to wind up the mulch film.

[0012] Furthermore, the cross-sections of the inner cavities of the take-up shaft and the take-up roller are both rectangular, and the end of the take-up shaft away from the take-up motor is threaded with an anti-derailment ring to limit the position of the take-up roller.

[0013] As a further description of the above technical solution: the cross-section of both the take-up shaft and the inner cavity of the take-up roller is rectangular, which effectively prevents the mulch film from sliding and loosening during the winding process, improves the stability and neatness of the winding, and ensures the stability of the take-up roller during the winding process by setting the anti-detachment ring, thus avoiding production accidents caused by the take-up roller falling off.

[0014] Furthermore, the inner wall of the cooling roller is uniformly welded with several heat-conducting pillars in a circumferential array, and the heat-conducting pillars are made of metallic copper.

[0015] As a further description of the above technical solution: by setting heat-conducting columns, the contact heat exchange area between the water and the cooling roller can be increased, thereby further improving the heat exchange effect.

[0016] Furthermore, a longitudinal beam is fixedly installed on the inner wall of the side plate, a lifting frame is slidably connected to the surface of the longitudinal beam, and a lower pressure roller is rotatably connected to the surface of the lifting frame, with the lower pressure roller corresponding to the cooling roller.

[0017] As a further description of the above technical solution: the biodegradable mulch film production and feeding equipment, through the combined use of the lifting frame and the lower pressure roller, achieves effective flattening of the mulch film during the conveying process under the action of gravity, and enables the mulch film to be tightly attached to the cooling roller, ensuring the cooling effect.

[0018] Furthermore, the surface of the lower pressure roller is symmetrically provided with spiral patterns in opposite directions, and a drive motor for driving the lower pressure roller to rotate is fixedly installed on the surface of the lifting frame. The rotation direction of the lower pressure roller is opposite to the conveying direction of the external mulch film.

[0019] As a further description of the above technical solution: the spiral pattern on the surface of the lower pressure roller and the rotation direction opposite to the conveying direction of the mulch film pull the mulch film from the center line to the front and back sides to flatten it, so that the mulch film can remain flat before winding and avoid wrinkling after winding.

[0020] The technical effects and advantages of this utility model are as follows:

[0021] 1. Compared with existing technologies, this biodegradable mulch film production feeding equipment lays the mulch film on the surface of cooling rollers and guide rollers during the mulch film production process, and uses the rotation of the winding rollers to wind the mulch film. During the mulch film transportation process, the mulch film is in close contact with the surface of the cooling rollers. Through the circulation of cooling water inside the cooling rollers, the mulch film is cooled by efficient heat conduction, and the cooling efficiency is significantly improved. At the same time, a deion fan blows cold air to the upper and lower sides of the mulch film through the conveyor plate, realizing multiple cooling of the mulch film, making up for the shortcomings of using only water cooling, improving the overall cooling effect. In addition, the use of deion fans also effectively reduces the problem of static electricity on the surface of the mulch film, ensuring the production quality of the mulch film.

[0022] 2. Compared with existing technologies, this biodegradable mulch film production feeding equipment, through the design of the winding assembly, uses a winding motor to drive the winding shaft to rotate, which in turn drives the winding roller to wind up the mulch film. The cross-sections of both the winding shaft and the inner cavity of the winding roller are rectangular, which effectively prevents the mulch film from slipping and loosening during the winding process, improving the stability and neatness of the winding. The anti-detachment ring ensures the stability of the winding roller during the winding process, avoiding production accidents caused by the winding roller falling off.

[0023] 3. Compared with existing technologies, this biodegradable mulch film production feeding equipment, through the combined use of a lifting frame and a lower pressure roller, effectively flattens the mulch film during the conveying process under the action of gravity, and enables the mulch film to fit tightly with the cooling roller, ensuring the cooling effect; through the spiral pattern on the surface of the lower pressure roller and the rotation direction opposite to the conveying direction of the mulch film, the mulch film is pulled and flattened from the center line to the front and back sides, so that the mulch film can remain flat before winding, avoiding the phenomenon of wrinkling after winding.

[0029] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The biodegradable mulch film production feeding device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1 to 4 This utility model provides a biodegradable mulch film production feeding device, including a base plate 1, with side plates 2 and a winding assembly respectively arranged on the upper surface of the base plate 1. There are two side plates 2, and guide rollers 24, water cooling assembly and air cooling assembly are respectively arranged between the two side plates 2 corresponding to the external mulch film.

[0031] A control panel 12 is fixedly installed on the surface of the side panel 2. The control panel 12 is electrically connected to an external power source via wires.

[0032] The winding assembly includes a winding frame 13 fixedly mounted on the surface of the base plate 1. A winding shaft 14 is rotatably connected to the surface of the winding frame 13. A winding motor 15 for driving the winding shaft 14 to rotate is coaxially fixedly mounted on the surface of the winding frame 13. A winding roller 16 is sleeved on the surface of the winding shaft 14. The cross-section of the inner cavity of both the winding shaft 14 and the winding roller 16 is rectangular.

[0033] It is worth noting that, through the design of the winding assembly, the winding motor 15 drives the winding shaft 14 to rotate, which in turn drives the winding roller 16 to wind up the mulch film. The cross-sections of the inner cavities of the winding shaft 14 and the winding roller 16 are both rectangular, which effectively prevents the mulch film from sliding and loosening during the winding process, and improves the stability and neatness of the winding.

[0034] The end of the take-up shaft 14 away from the take-up motor 15 is threaded with an anti-derailment ring 17 that limits the position of the take-up roller 16.

[0035] Furthermore, the anti-detachment ring 17 ensures the stability of the take-up roller 16 during the take-up process, preventing production accidents caused by the take-up roller 16 falling off.

[0036] The water-cooling assembly includes a cooling pipe 3 rotatably connected to the inner wall of the side plate 2. A cooling roller 4 is fixedly connected to the middle section of the cooling pipe 3. A water tank 5 is fixedly installed on the surface of the side plate 2. A ventilation and heat dissipation window is reserved on the surface of the water tank 5. A fan 25 is embedded in the top of the water tank 5, and the air outlet of the fan 25 faces the inside of the water tank 5. A pump body 6 is fixedly installed at the bottom of the water tank 5. The liquid inlet of the pump body 6 extends to the bottom of the water tank 5. A delivery pipe 7 is fixedly installed at the liquid outlet of the pump body 6. The other end of the delivery pipe 7 is connected to one end of the cooling pipe 3 through a rotating pipe joint. The other end of the cooling pipe 3 is fixedly connected to a return water pipe 8 through a rotating pipe joint. The other end of the return water pipe 8 is connected to the top of the water tank 5.

[0037] In the production process of this biodegradable mulch film, the mulch film is laid on the surface of the cooling roller 4 and the guide roller 24, and the mulch film is wound by the rotation of the winding roller 16. During the transportation of the mulch film, the mulch film is in close contact with the surface of the cooling roller 4. The mulch film is cooled by efficient heat conduction through the circulation of cooling water inside the cooling roller 4, and the cooling efficiency is significantly improved.

[0038] The inner wall of the cooling roller 4 is uniformly welded with several heat-conducting pillars 18 in a circumferential array. The heat-conducting pillars 18 are made of metallic copper.

[0039] By setting the heat-conducting column 18, the contact heat exchange area between the water and the cooling roller 4 can be increased, thereby further improving the heat exchange effect.

[0040] A longitudinal beam 19 is fixedly installed on the inner wall of the side plate 2. A lifting frame 20 is slidably connected to the surface of the longitudinal beam 19. A lower pressure roller 21 is rotatably connected to the surface of the lifting frame 20. The lower pressure roller 21 is positioned corresponding to the cooling roller 4.

[0041] This biodegradable mulch film production and feeding equipment uses a combination of lifting frame 20 and pressure roller 21 to effectively flatten the mulch film during the conveying process by utilizing gravity, and also enables the mulch film to fit tightly with the cooling roller 4 to ensure the cooling effect.

[0042] The surface of the lower pressure roller 21 is symmetrically provided with spiral patterns 22 in opposite directions. The surface of the lifting frame 20 is fixedly mounted with a drive motor 23 for driving the lower pressure roller 21 to rotate. The rotation direction of the lower pressure roller 21 is opposite to the conveying direction of the external mulch film.

[0043] The spiral grooves 22 on the surface of the lower pressure roller 21 and the rotation direction opposite to the conveying direction of the mulch film pull the mulch film from the center line to the front and back sides to flatten it, so that the mulch film can remain flat before winding and avoid wrinkling after winding.

[0044] The air-cooled assembly includes a deion fan 9 fixedly installed on the surface of the side plate 2. Two conveying plates 10 are fixedly installed at the air outlet end of the deion fan 9. The two conveying plates 10 extend between the two side plates 2, and a gap is reserved between the two conveying plates 10 for the external ground film to pass through. Several air outlet holes 11 are opened on the adjacent side of the two conveying plates 10.

[0045] It is worth noting that during the winding and conveying of the mulch film, the deion fan 9 blows cold air to the upper and lower sides of the mulch film through the conveyor plate 10, achieving multiple cooling of the mulch film. This makes up for the shortcomings of using only water cooling and improves the overall cooling effect. In addition, the use of the deion fan 9 also effectively reduces the problem of static electricity on the surface of the mulch film, ensuring the production quality of the mulch film.

[0046] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
