A film rolling machine for producing biodegradable mulch film

Abstract

This utility model discloses a film winding machine for producing biodegradable mulch film, belonging to the field of film winding machine technology. It includes a frame, inside which a winding roller, a guide roller, a movable roller, and a feed roller are arranged horizontally in sequence. By setting up the horizontally distributed winding roller, guide roller, movable roller, and feed roller, this utility model allows for the winding of biodegradable mulch film. The feed roller first pulls the extruded and cooled biodegradable mulch film into the frame. The biodegradable mulch film then passes through the movable roller and guide roller before being wound by the winding roller. During this process, by controlling the sequential activation of the feed roller and winding roller, redundancy is created between the winding roller and the feed roller. This redundant mulch film releases tension between the guide roller and the movable roller. After the tension is released, the biodegradable mulch film is wound by the winding roller, effectively preventing excessive tension that could cause bursting and also preventing excessive tension released by the winding roller that could cause the biodegradable mulch film to be stretched and deformed.

Description

Technical Field

[0001] This utility model relates to the field of film rolling machine technology, and in particular to a film rolling machine for producing degradable mulch film. Background Technology

[0002] Biodegradable mulch film is an environmentally friendly agricultural covering material made from biodegradable masterbatches such as crop straw, corn starch, or potato starch. It decomposes naturally through the action of microorganisms. Through an oxidation-biological dual degradation mechanism, it can decompose polymer materials into carbon dioxide, water, and organic matter. It can be integrated into the soil without artificial recycling. In crop cultivation, it has functions such as warming and moisture retention, weed suppression, water conservation, and drought resistance. It can increase the yield of fresh corn ears by 32.2% and increase the soil temperature of strawberries by 2-4℃.

[0003] In existing technologies, biodegradable mulch film is wound up using a film winding machine after production. For example, a film winding machine for mulch film production, with announcement number CN221700627U, includes an operation panel. Two mounting plates are symmetrically fixed on the upper surface of the operation panel. Two sets of connecting plates are arranged vertically between the two sides of the two mounting plates. Two flattening rollers are symmetrically arranged in each of the two sets of connecting plates. Two sets of connecting frames are arranged between the two sides of the two mounting plates and between the two sets of connecting plates. Several connecting rods are movably and evenly spaced through the surface of each set of connecting frames. A dust removal brush is fixedly connected to one end of each of the connecting rods. A spring is sleeved and connected to the outside of the connecting rods and between the connecting frame and the dust removal brush. This device improves the cleaning effect of the dust removal brush on the mulch film. At the same time, the two dust removal brushes tightly adhere to the two sides of the mulch film, thereby smoothing out the wrinkles on the surface of the mulch film and improving the winding effect.

[0004] However, existing film winding machines are usually designed for traditional mulch films. Unlike traditional mulch films, biodegradable mulch films (especially those with high PLA content) have poor extensibility and high brittleness. Therefore, they require lower tension during winding to avoid stretching during the winding process, which would lead to uneven thickness. They also need to avoid stress residue after winding, which could cause the film to burst. Existing film winding machines cannot reasonably control the tension according to the characteristics of biodegradable mulch films when winding them, which has a significant impact on the final yield of biodegradable mulch film products.

[0005] Therefore, it is necessary to invent a film rolling machine for the production of degradable mulch film to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a film rolling machine for the production of biodegradable mulch film, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a film rolling machine for producing degradable mulch film, comprising a frame, wherein a winding roller, a guide roller, a movable roller, and a feeding roller are arranged horizontally in sequence inside the frame; a feeding motor and a winding motor are fixedly mounted at the bottom of the frame; a belt assembly is provided between the output shaft of the feeding motor and one end of the feeding roller; a transmission rod is rotatably mounted at the bottom of the frame via bearings; transmission arms are fixedly mounted at both ends of the transmission rod; the two ends of the movable roller are respectively movably connected to the top ends of the two transmission arms on their adjacent sides via bearings; a swing arm is fixedly mounted at one end of the transmission rod, and the swing arm is located outside the frame; a cylinder is rotatably mounted at the end of the swing arm away from the transmission rod via a pin; a connecting seat is fixedly mounted at one end of the cylinder, and the connecting seat is rotatably mounted on the outside of the frame via a pin.

[0008] Preferably, support seats are fixedly installed on both inner walls of the frame, and the take-up roller is located between the two support seats.

[0009] Preferably, each of the two support seats has a support shaft rotatably mounted inside via bearings, and a belt assembly is provided between one of the support shafts and the winding motor.

[0010] Preferably, a connecting block is fixedly installed at one end of each of the two support shafts that are close to each other, and a clamp is fixedly installed on one side of each of the two connecting blocks that are close to each other. The clamp is designed with a "C" shape, and the two ends of the take-up roller are located inside the two clamps respectively.

[0011] Preferably, each of the two clamping seats has a clamping block on one side, and the clamping block is designed with an arc shape. Both ends of the clamping seat are fixedly installed with fixing blocks, and both ends of the clamping block are fixedly installed with connecting ears. The connecting ears and the fixing blocks are connected by bolts.

[0012] Preferably, a limiting block is fixedly installed on the inner side of both the clamping seat and the clamping block, and the inner side of the limiting block has an arc-shaped structure.

[0013] Preferably, the inner side of the limiting block is provided with a plurality of protrusions, and the plurality of protrusions are all rubber blocks.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. This utility model, by setting up horizontally distributed take-up rollers, guide rollers, movable rollers, and feed rollers, allows for the following process when winding biodegradable mulch film: the feed roller first pulls the extruded and cooled biodegradable mulch film into the machine frame; the biodegradable mulch film then passes through the movable roller and guide roller in sequence before being wound up by the take-up roller. During this process, by controlling the sequential start of the feed roller and the take-up roller, redundancy is created between the take-up roller and the feed roller in the biodegradable mulch film. At this time, the redundant mulch film completes the tension release between the guide roller and the movable roller. After the tension is released, the biodegradable mulch film is wound up by the take-up roller, which can effectively avoid excessive tension causing the roll to burst, and also avoid excessive tension released by the take-up roller on the biodegradable mulch film, which could cause the biodegradable mulch film to be stretched and deformed, thereby effectively improving the yield of biodegradable mulch film after roll formation.

[0016] 2. By setting up a movable roller, the movable roller can swing between the guide roller and the feed roller. During the process of the feed roller pulling the degradable mulch film, the movable roller can press the degradable mulch film tightly against the outer surface of the feed roller to ensure that there is a sufficiently strong friction between the feed roller and the degradable mulch film to achieve the traction of the degradable mulch film. This ensures that the degradable mulch film can be continuously pulled during the winding process, thereby ensuring the stable progress of the winding process. Attached Figure Description

[0023] 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.

[0024] This utility model provides, for example Figure 1-5 The illustrated degradable mulch film production film rolling machine includes a frame 1. Inside the frame 1, a take-up roller 2, a guide roller 3, a movable roller 4, and a feed roller 5 are arranged horizontally in sequence. A feed motor 6 and a take-up motor 7 are fixedly mounted at the bottom of the frame 1. A belt assembly is provided between the output shaft of the feed motor 6 and one end of the feed roller 5. A transmission rod 8 is rotatably mounted at the bottom of the frame 1 via bearings. Transmission arms 9 are fixedly mounted at both ends of the transmission rod 8. The two ends of the movable roller 4 are respectively connected to the two transmission arms 9 via bearings. One end of the transmission rod 8 is fixedly connected to a swing arm 10, which is located on the outside of the frame 1. The end of the swing arm 10 away from the transmission rod 8 is rotatably mounted with a cylinder 11 via a pin. One end of the cylinder 11 is fixedly mounted with a connecting seat 12, which is rotatably mounted on the outside of the frame 1 via a pin. The cylinder 11 can drive the swing arm 10 to move during the extension or retraction process. The swing arm 10 can drive the transmission arm 9 to move through the transmission rod 8, so as to adjust the position of the movable roller 4.

[0025] Support seats 13 are fixedly installed on both inner walls of the frame 1. The take-up roller 2 is located between the two support seats 13. The support shaft 14 is rotatably installed inside the two support seats 13 through bearings. A belt assembly is provided between one support shaft 14 and the take-up motor 7.

[0026] Two support shafts 14 are each fixedly mounted with a connecting block 15 at one end close to each other. Two connecting blocks 15 are each fixedly mounted with a clamp 16 on one side close to each other. The clamp 16 is designed with a "C" shape. The two ends of the take-up roller 2 are located inside the two clamps 16 respectively. One side of each clamp 16 is provided with a clamp 17, which is designed with an arc shape. Fixed blocks 18 are fixedly mounted at both ends of the clamp 16. Connecting ears 19 are fixedly mounted at both ends of the clamp 17. The connecting ears 19 and the fixed blocks 18 are connected by bolts. A through hole is opened in the middle of the connecting ear 19. A screw hole is opened in the middle of the fixed block 18. After the bolt passes through the through hole in the middle of the connecting ear 19, it is screwed into the screw hole to complete the connection and fixation between the connecting ear 19 and the fixed block 18.

[0027] Limiting blocks 20 are fixedly installed on the inner sides of both the clamping seat 16 and the clamping block 17. The inner side of the limiting block 20 has an arc-shaped structure. Multiple protrusions 21 are fixedly provided on the inner side of the limiting block 20. All protrusions 21 are rubber blocks. The protrusions 21 are used to increase the friction between the limiting block 20 and the winding roller 2, so as to ensure that the clamping seat 16 can drive the winding roller 2 to rotate stably to complete the winding.

[0028] Working principle of this utility model:

[0029] In use, the frame 1 can be installed at the end of the biodegradable mulch film production line. After extrusion and cooling, the biodegradable mulch film reaches the end of the production line. At this point, the biodegradable mulch film is guided through the feed roller 5, movable roller 4, and guide roller 3 to the surface of the take-up roller 2, where the end of the biodegradable mulch film is fixed. Then, the feed motor 6 and the take-up motor 7 are started sequentially. The feed motor 6 first drives the feed roller 5 to rotate, and the feed roller 5 uses friction to pull the biodegradable mulch film, guiding it above the movable roller 4. Since the take-up motor 7 has not yet started, the biodegradable mulch film is pulled by the feed roller 5... The film then reaches the space between the take-up roller 2 and the feed roller 5, and pauses briefly between them. At this time, redundant degradable film is formed between the take-up roller 2 and the feed roller 5. The movable roller 4 and the guide roller 3 can support the degradable film. Due to the influence of gravity, the degradable film naturally falls between the movable roller 4 and the guide roller 3 to release the tension of the degradable film. After the feed motor 6 starts for a short period of time, the take-up motor 7 starts. The take-up motor 7 drives the support shaft 14 and the clamp 16 to rotate. The clamp 16 drives the take-up roller 2 to rotate. The take-up roller 2 then winds up the degradable film after the tension has been released.

[0030] After the degradable mulch film is guided past the feed roller 5, the control cylinder 11 drives the swing arm 10 to rotate. The swing arm 10 drives the transmission arm 9 to swing through the transmission rod 8. The transmission arm 9 drives the movable roller 4 to move, so that the movable roller 4 moves in the direction of the feed roller 5. At this time, the movable roller 4 presses the degradable mulch film tightly on the surface of the feed roller 5 to ensure that there is a sufficiently strong friction between the feed roller 5 and the degradable mulch film to ensure the traction effect.

[0031] During the use of the device, the take-up roller 2 needs to be disassembled and replaced before and after take-up. At this time, control the take-up motor 7 to stop and remove the bolts between the connecting ear 19 and the fixing block 18. Then the clamping block 17 can be separated from the clamping seat 16. At this time, the two ends of the take-up roller 2 can be taken out from the two clamping seats 16 and installed, thereby realizing the disassembly and replacement of the take-up roller 2.

[0032] It should be noted that the feeding motor 6 and the winding motor 7 in this embodiment adopt the corresponding structure in the prior art and are equipped with a power supply and controller. The belt group involved in this embodiment also adopts the corresponding structure in the prior art, which includes a pulley and a belt. The winding roller 2 in this embodiment adopts the roller structure used for winding mulch film in the prior art. It can be a single roller or a combination of a clamp and a roller. As long as both ends can be inserted into the clamp 16 and limited, its model is not limited. The guide roller 3, the movable roller 4 and the feeding roller 5 in this embodiment are all rubber rollers.

[0033] It should be further explained that in this embodiment, the degradable mulch film passes sequentially above the feed roller 5, between the feed roller 5 and the movable roller 4, and above the guide roller 3 before reaching the surface of the take-up roller 2. The specific trajectory is shown in the attached figure. Figure 2 As shown.

[0034] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
