Description

Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment, and specifically to a film rolling device and film rolling method. Background Technology

[0002] Currently, a large portion of arable land in my country still uses plastic film for planting. Due to its functions of retaining moisture, providing insulation, and controlling weeds and pests, plastic film is increasingly favored by growers. However, with the increasing use and coverage area of ​​plastic film, it has led to severe white pollution, soil damage, and water pollution, resulting in farmland abandonment and ecological imbalance. Existing plastic film recycling machines on the market, during the film collection process, experience increasingly severe entanglement between the film and the collection components as the working stroke increases. This makes film separation difficult after the work is completed, hindering film recycling and subsequent processing and utilization. Summary of the Invention

[0003] The purpose of this invention is to provide a film winding device and method to solve the technical problems in the prior art where the separation of the mulch film and the film collection component is difficult, which is detrimental to the recycling and subsequent processing and utilization of the mulch film.

[0004] In view of the above objectives, in a first aspect, this application provides a film winding component, comprising: a film winding roller, and a drive shaft, a gear assembly and a limiting assembly disposed inside the film winding roller;

[0005] The tooth assembly includes a fixed disk assembly, a tooth fixing member, and tooth spikes;

[0006] Multiple fixed disc assemblies are mounted on the drive shaft at a first preset interval. Each fixed disc assembly includes two fixed disc bodies arranged at a second preset interval. Multiple protruding toothed fasteners are provided on the circumferential side of each fixed disc body. The multiple toothed fasteners on the circumferential side of the two fixed disc bodies are arranged opposite to each other, and a fixing pin is connected between the two toothed fasteners arranged opposite to each other.

[0007] The end of the nail tooth is rotatably sleeved on the fixing pin, so that the nail tooth can extend into the second preset interval or extend out of the second preset interval;

[0008] The limiting component includes multiple limiting rods, which are fixed at a preset angle in the circumferential direction of the inner wall of the film roll and extend axially along the inner wall of the film roll. The number of limiting rods is the same as the number of toothed fasteners on a single fixed disc.

[0009] The film-winding roller has multiple through holes on its wall, and the number and position of the through holes are adapted to the number and position of the spike teeth.

[0010] The drive shaft drives the gear assembly to rotate in the first rotation direction. When the nail tooth fixing member rotates to the first position close to the limiting rod, the nail tooth extends out of the through hole on the cylinder wall of the film roll, so that the film roll and the gear assembly are linked.

[0011] The film winding roller is driven to rotate in the second rotation direction. When the film winding roller rotates to a second position away from the limiting rod, the spike teeth retract to the second preset interval under the restriction of the hole wall of the through hole.

[0012] Furthermore, the nail teeth fasteners and the assembly angles of the nail teeth on the multiple fixed disk assemblies are the same.

[0013] Furthermore, each of the fixed disk assemblies is configured with three spike teeth.

[0014] Secondly, this application provides a film winding device, including a frame, a mounting plate, a first support frame, a second support frame, a first drive assembly, a second drive assembly, and the aforementioned film winding components.

[0015] The film winding component is provided in four parts. Each pair of film winding components arranged coaxially forms a group of film winding assemblies. The two groups of film winding assemblies are arranged sequentially back and forth along the traveling direction of the frame. In each group of film winding assemblies, the two film winding components are detachably connected by a docking device provided on the first end of the drive shaft.

[0016] The mounting plates are connected to both sides of the frame;

[0017] The first support frame and the second support frame are respectively connected to the frame via telescopic connectors and can move horizontally relative to the frame along the axial direction of the film roll member;

[0018] In each set of film winding assemblies, the film winding rollers pass through the corresponding mounting plates. Two first drive assemblies are provided, one on each of the first support frame and the second support frame. The first drive assemblies are connected to the film winding rollers on the same side of the mounting plate through the first transmission assembly, and are used to drive the film winding rollers to rotate.

[0019] In each set of film winding assemblies, the second end of the drive shaft extends out of the film winding roller and is connected to the first support frame and the second support frame through a bearing-bearing support.

[0020] The second drive assembly is connected to the second end of the drive shaft via the second transmission assembly, and is used to drive the drive shaft to rotate.

[0021] Furthermore, the docking device includes a docking sleeve, one end of which is connected to the first end of the drive shaft, and the other end of which is provided with connecting teeth. In each set of film winding assemblies, the two docking sleeves are connected to each other through the connecting teeth.

[0022] Furthermore, the first support frame and the second support frame move in opposite directions.

[0023] Furthermore, the first transmission assembly includes a first driving gear, a first driven gear disk, and a first chain; the first driven gear disk is fixed on two film rolling rollers located on the same side of the mounting plate, the first driving gear is connected to the first drive assembly, and the first chain is sleeved on the first driving gear and the first driven gear.

[0024] Furthermore, the second transmission assembly includes a second driving gear, a second driven gear disk A, a second driven gear disk B, a second chain A, and a second chain B. The second driving gear is connected to the second drive assembly. Two second driven gear disks A are provided and are respectively fixed to the second end of the same transmission shaft. The second driven gear disk B is fixed to the second end of another transmission shaft. The second chain A is sleeved on the second driving gear and one of the second driven gear disks A, and the second chain B is sleeved on the second driven gear disk B and the other second driven gear disk A.

[0025] Furthermore, it also includes multiple guide support components, each of which is a telescopic rod. The fixed end of the telescopic rod is connected to the frame, and the telescopic end of the telescopic rod is connected to the corresponding first support frame and second support frame.

[0026] Thirdly, this application provides a film winding method applied to the aforementioned film winding apparatus, the film winding method comprising:

[0027] In roll film mode:

[0028] The first support frame and the second support frame are moved relative to each other by means of telescopic connectors, so that two of the film roll components in each set of film roll assemblies are connected by a docking device.

[0029] The transmission shaft is driven to rotate in the first rotation direction by the second drive assembly and the second transmission assembly. The transmission shaft is linked with the gear assembly, causing the spike teeth to extend out of the through holes on the cylinder wall of the film winding roller. At the same time, the film winding roller is linked with the gear assembly to perform film winding operation.

[0030] In film removal mode:

[0031] The first drive assembly and the first transmission assembly drive the film roll to rotate in the second rotation direction, and the spike teeth retract to the second preset interval under the restriction of the hole wall of the through hole;

[0032] The telescopic connector drives the first support frame and the second support frame to move in opposite directions until they reach the preset film unloading position, causing the film rolls hanging on each film roll assembly to detach.

[0033] By adopting the above technical solutions, the film winding component, film winding device, and film winding method provided in this application have the following technical advantages compared with the prior art:

[0034] In this film-rolling component, the drive shaft drives the gear assembly to rotate in the first rotation direction. When the nail tooth fixing component rotates to the first position close to the limit rod, the nail tooth extends out of the through hole on the cylinder wall of the film-rolling roller, so that the film-rolling roller and the gear assembly are linked. In this state, the mulch film is hung and passes through the nail tooth, so that the mulch film can be wound on the film-rolling roller, and the winding operation of the mulch film can be realized.

[0035] When the film-winding roller is driven to rotate in the second rotation direction, and the film-winding roller rotates to the second position away from the limiting rod, the nail teeth retract to the second preset interval under the restriction of the hole wall. In this state, the nail teeth disengage from the mulch film, which facilitates the separation operation between the mulch film and the film-winding roller. This effectively alleviates the technical problems in the prior art where the separation of the mulch film and the film-collecting component is difficult, which is not conducive to the recycling of the mulch film and subsequent processing and utilization of the mulch film.

Detailed Implementation

[0046] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Example 1

[0048] like Figures 1 to 4 As shown in the embodiment of this application, a film winding component 100 includes: a film winding roller 110, and a drive shaft 120, a gear assembly 130 and a limiting assembly 140 disposed inside the film winding roller 110;

[0049] The tooth assembly 130 includes a fixed disk assembly 131, a tooth fixing member 132, and a tooth 133;

[0050] Multiple fixed disc assemblies 131 are mounted on the drive shaft 120 at a first preset interval. Each fixed disc assembly 131 includes two fixed disc bodies arranged at a second preset interval. Multiple protruding toothed fasteners 132 are provided on the circumferential side of each fixed disc body. In each fixed disc assembly 131, the multiple toothed fasteners 132 on the circumferential side of the two fixed disc bodies are arranged opposite to each other, and a fixing pin is connected between the two toothed fasteners 132 arranged opposite to each other.

[0051] The end of the nail tooth 133 is rotatably sleeved on the fixing pin, so that when in use, the nail tooth 133 can extend into the second preset interval or extend out of the second preset interval;

[0052] The limiting assembly 140 includes multiple limiting rods, which are fixed at a preset angle in the circumferential direction of the inner wall of the film roll 110 and extend axially along the inner wall of the film roll 110. The number of limiting rods is the same as the number of nail tooth fasteners 132 on a single fixed disc.

[0053] The film winding roller 110 has multiple through holes 111 on its cylinder wall, and the number and position of the through holes 111 are adapted to the number and position of the nail teeth 133.

[0054] In application, when the drive shaft 120 drives the gear assembly 130 to rotate in the first rotation direction, when the nail tooth fixing member 132 rotates to the first position close to the limit rod, the nail tooth 133 extends out of the through hole 111 on the cylinder wall of the film rolling roller 110, so that the film rolling roller 110 and the gear assembly 130 are linked together, thereby winding the film.

[0055] The film-winding roller 110 is driven to rotate in the second rotation direction. When the film-winding roller 110 rotates to the second position away from the limiting rod, the nail tooth 133 retracts to the second preset interval under the restriction of the hole wall of the through hole. At this time, the nail tooth 133 can be disengaged from the film roll.

[0056] It should be noted that when the spike tooth 133 is in the retracted state, its tip contacts the inner wall of the through hole on the film winding roller 110. This ensures that the spike tooth 133 can smoothly pass through the through hole and extend to the outside of the film winding roller 110.

[0057] As a preferred embodiment, the mounting angles of the nail teeth 132 and nail teeth 133 on the multiple fixed plate assemblies 131 are the same.

[0058] As a preferred embodiment, each fixed disk assembly 131 is configured with three spike teeth 133.

[0059] In the film winding component 100 provided in this embodiment, the drive shaft 120 drives the tooth assembly 130 to rotate in the first rotation direction. When the nail tooth fixing member 132 rotates to the first position close to the limit rod, the nail tooth 133 extends out of the through hole on the cylinder wall of the film winding roller 110, so that the film winding roller 110 and the tooth assembly 130 are linked. In this state, the mulch film is hung and passes through the nail tooth 133, so that the mulch film can be wound on the film winding roller 110, and the winding operation of the mulch film can be realized.

[0060] When the film-winding roller 110 is driven to rotate in the second rotation direction, and the film-winding roller 110 rotates to the second position away from the limiting rod, the nail tooth 133 retracts to the second preset interval under the restriction of the hole wall of the through hole. In this state, the nail tooth 133 disengages from the mulch film, which facilitates the separation operation between the mulch film and the film-winding roller 110. This effectively alleviates the technical problems in the prior art where the separation of the mulch film and the film-collecting component is difficult, which is not conducive to the recycling of the mulch film and subsequent processing and utilization of the mulch film.

[0061] Example 2

[0062] like Figure 5 , Figure 6 and Figure 7 As shown, this embodiment provides a film winding device 200, including a frame 210, a mounting plate 220, a first support frame 230, a second support frame 240, a first drive assembly 250, a second drive assembly 260, and the film winding component 100 of the above embodiment 1.

[0063] The machine includes four film winding components 100. Each pair of coaxially arranged film winding components 100 forms a film winding assembly. The two film winding assemblies are arranged sequentially back and forth along the travel direction of the frame 210. In each film winding assembly, the two film winding components 100 are detachably connected through a docking device 270 provided on the first end of the drive shaft 120.

[0064] Mounting plates 220 are connected to both sides of the frame 210 respectively; the first support frame 230 and the second support frame 240 are located on the outside of the two mounting plates 220 respectively. The first support frame 230 and the second support frame 240 are connected to the frame 210 through telescopic connectors 280 and can move horizontally relative to the frame 210 along the axial direction of the film winding member 100; optionally, the telescopic connectors 280 can be hydraulic cylinders, pneumatic cylinders or electric cylinders.

[0065] In each set of film winding assemblies, two film winding components 100 have film winding rollers 110 passing through corresponding mounting plates 220, i.e., the mounting plates 220 are provided with holes to facilitate the film winding rollers 110 passing through; two first drive assemblies 250 are provided, one on the first support frame 230 and one on the second support frame 240. The first drive assembly 250 is connected to the two film winding rollers 110 on the same side of the mounting plate 220 through a first transmission assembly, and is used to drive the film winding rollers 110 to rotate;

[0066] In each set of film winding assemblies, the second end of the drive shaft 120 extends out of the film winding roller 110 and is connected to the first support frame 230 and the second support frame 240 through a bearing-bearing support.

[0067] The second drive assembly 260 is connected to the second end of the drive shaft 120 via the second transmission assembly, and is used to drive the drive shaft 120 to rotate, thereby adjusting the position of the gear assembly 130 relative to the film roll 110.

[0068] As a preferred embodiment, the docking device 270 in this embodiment includes a docking sleeve. One end of the docking sleeve is connected to the first end of the drive shaft 120, and the other end of the docking sleeve is provided with a connecting tooth 271. In each set of film winding assemblies, the two docking sleeves are connected to each other through the connecting tooth 271 among the two film winding members 100.

[0069] In practical applications, when the telescopic connector 280 drives the first support frame 230 and the second support frame 240 to move relative to each other (and simultaneously move towards the center of the frame 210), the two film-rolling components 100 in each film-rolling assembly also move relative to each other, so that the two mating sleeves are connected by the connecting teeth 271. Then, the second drive assembly 260 is used to drive one of the drive shafts 120 to rotate. Through the meshing action of the connecting teeth 271, the other coaxially arranged drive shaft 120 is linked, and the film-rolling component 100 is used to roll up the film.

[0070] When film removal is required, the telescopic connector 280 drives the first support frame 230 and the second support frame 240 to move away from each other (and move to both sides of the frame 210 at the same time), and the connecting teeth 271 between the two mating sleeves separate, which facilitates the film removal operation.

[0071] It should be noted that since every two coaxially arranged film winding components 100 form a film winding assembly, the overall length of the film winding assembly can be increased during film winding operations, thereby improving film winding efficiency. Furthermore, a single second drive assembly 260 can drive four film winding components 100 to rotate synchronously, improving film winding efficiency while optimizing the product structure. Additionally, the purpose of arranging the two sets of film winding assemblies sequentially along the travel direction of the frame 210 is to ensure that, during film winding operations, if the first set of film winding assemblies fails to wind up the film, the film will be wound up by the other set of film winding assemblies, thus avoiding the problem of ineffective film winding.

[0072] In a preferred embodiment, the first transmission assembly includes a first driving gear 251, a first driven gear disk 252, and a first chain 253. The first driven gear disk 252 is fixed on two film-rolling rollers 110 located on the same side of the mounting plate 220. The first driving gear 251 is connected to the first drive assembly, and the first chain 253 is sleeved on the first driving gear 251 and the first driven gear. In application, the first drive assembly drives the first driving gear 251 to rotate, and the first driven gear disk 252 is linked with the first driving gear 251 through the first chain 253, thereby driving the two film-rolling rollers 110 to rotate in the second rotation direction. It should be noted that when the film-rolling rollers 110 rotate, the transmission shaft 120 remains stationary, and the second rotation direction is clockwise, so that the nail teeth 133 can retract to the second preset interval under the constraint of the hole wall of the through hole, thereby allowing the nail teeth 133 to disengage from the film roll.

[0073] In a preferred embodiment, the second transmission assembly includes a second driving gear 261, a second driven gear disk A262, a second driven gear disk B263, a second chain A264, and a second chain B265. The second driving gear 261 is connected to the second drive assembly 260. Two second driven gear disks A262 are provided and fixed to the second end of the same transmission shaft 120 respectively. The second driven gear disk B263 is fixed to the second end of another transmission shaft 120. The second chain A264 is sleeved on the second driving gear 261 and one of the second driven gear disks A262. The second chain B265 is sleeved on the second driven gear disk B263 and the other second driven gear disk A262.

[0074] In application, the second drive assembly 260 drives the second drive gear 261 to rotate. The second drive gear 261 drives one of the second driven gear disks A262 to rotate via the second chain A264. The other second driven gear disk A262 drives the second chain B265 to rotate via the second chain B265. Through the above transmission structure, the drive shafts 120 of the two sets of film winding assemblies can rotate synchronously, thereby causing the nail teeth 133 to extend out of the through holes on the cylinder wall of the film winding roller 110, so that the film winding roller 110 and the tooth assembly 130 are linked to perform film winding operation.

[0075] As a preferred embodiment, the film winding device 200 in this embodiment further includes a plurality of guide support components 290. The guide support components 290 adopt telescopic rods. The fixed end of the telescopic rod is connected to the frame 210, and the telescopic end of the telescopic rod is connected to the corresponding first support frame and second support frame. The guide support components 290 guide the movement direction of the connection between the first support frame and the second support frame, and ensure the stability of the movement.

[0076] Furthermore, this application embodiment also provides a film winding method, which is applied to the film winding device 200 provided in the above-described embodiment two. Specifically, the film winding method includes: a film winding mode and a film unwinding mode, wherein:

[0077] In roll film mode:

[0078] The telescopic connector 280 drives the first support frame 230 and the second support frame 240 to move relative to each other, so that the two film winding components 100 in each group of film winding assemblies are connected by the docking device 270.

[0079] The second drive assembly 260 and the second transmission assembly drive the transmission shaft 120 to rotate in the first rotation direction (clockwise direction). The transmission shaft 120 is linked with the gear assembly 130, causing the spike teeth 133 to extend out of the through holes on the cylinder wall of the film winding roller 110. At the same time, the film winding roller 110 is linked with the gear assembly 130 to perform film winding operation.

[0080] In the film rolling mode, four film rolling components 100 in two sets of film rolling assemblies can be docked and rotated synchronously. Since the film may be attached to soil or other debris or interfered with by other factors, when the first set of film rolling assemblies does not roll up the film, the second set of film rolling assemblies can roll up the film, thereby avoiding the problem of the film not being able to be rolled up effectively.

[0081] Moreover, by using the second drive component 260 and the second transmission component together, synchronous driving of the quad-core winding component 100 can be achieved, optimizing the product structure and reducing additional energy consumption.

[0082] In film removal mode:

[0083] The first drive assembly 250 and the first transmission assembly drive the film winding roller 110 to rotate in the second rotation direction (clockwise direction). The spike teeth 133 retract to the second preset interval under the restriction of the hole wall of the through hole. At this time, the spike teeth 133 completely disengage from the film wound on the film winding roller 110.

[0084] The telescopic connector 280 drives the first support frame 230 and the second support frame 240 to move away from each other until they reach the preset film unloading position. Under the restriction of the mounting plate 220, the film hanging on each roll assembly along both sides of the frame 210 is detached.

[0085] In summary, the technical solution of this application solves the problems of low efficiency and high difficulty in operation of existing mechanical film unloading. It has the advantages of simple structure, stable operation and convenient operation, and meets the requirements of residual film recycling and film unloading operation. It facilitates the separation of the mulch film from the film rolling roller 110. In turn, it effectively alleviates the technical problems of separation difficulties between the mulch film and the film collection component in the existing technology, which are not conducive to the recycling of mulch film and subsequent processing and utilization of mulch film.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
