Description

Technical Field

[0001] This utility model relates to a film feeding mechanism for a seed cotton baling machine, belonging to the field of seed cotton baling and film feeding technology. Background Technology

[0002] Seed cotton is cotton picked by cotton farmers. After processing, the cottonseed is removed, leaving lint. Generally, cotton yield refers to lint yield. Seed cotton byproducts also have certain uses. Seed cotton is processed using a gin to separate the cotton fibers from the seeds. The separated cottonseed is called raw cottonseed, which still contains a small amount of short fibers, or lint. Lint has considerable value. Generally, raw cottonseed goes to a delinting workshop for delinting (except for cottonseed used for seed production, where the lint is treated chemically). Depending on the process requirements, the delinting machine separates the cotton lint into three layers: Layer I lint (such as banknote paper), and Layers II and III lint (used in chemical processes, such as producing film and smokeless gunpowder for military use). After the cottonseed is delinted, it is called bare cottonseed. After processing, it can be used as livestock feed and substrate for cultivating edible fungi. When the cottonseed is sold, it usually needs to be packaged. At this time, a cottonseed packaging and film conveying mechanism is needed to transport the film for packaging the cottonseed to facilitate packaging.

[0003] The existing seed cotton baling and film feeding mechanism still has some problems in use. During the conveying of the baling film, since the film feeding roller is usually a fixed size, it can only adapt to film rolls of a specific size and is difficult to adapt to film rolls of different sizes. When the width of the film roll does not match the width of the film feeding roller, the film roll may shift or run off course during the film feeding process, and it is impossible to stabilize the position of different film rolls. Utility Model Content

[0004] The purpose of this utility model is to provide a film feeding mechanism for a cotton baler. This utility model has a simple structure and is easy to use. It can stabilize the position of film rolls of different widths and prevent the film rolls from shifting or deviating during the feeding process, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A film feeding mechanism for a seed cotton baler includes a processing table. Multiple sets of support plates are symmetrically mounted on the surface of the processing table. One set of support plates is symmetrically rotatably connected to an active film feeding roller. Two sets of support plates are symmetrically rotatably connected to driven film feeding rollers. Adjusting plates are symmetrically mounted between the two sets of driven film feeding rollers. A U-shaped clamping plate is slidably connected between the two adjusting plates. A pull rod is slidably connected within through holes on the surfaces of the support plates and the adjusting plates. One end of each pull rod passes through the support plate and the adjusting plate and is connected to one side surface of the U-shaped clamping plate.

[0007] Furthermore, a push plate is installed at the same end of both pull rods, and a return spring is sleeved on the surface of the pull rod. One end of the return spring is connected to the push plate, and the other end of the return spring is connected to the support plate.

[0008] Furthermore, two pull rods are symmetrically installed on the surface of the U-shaped clamp, and the two pull rods are respectively installed on both sides of the U-shaped clamp.

[0009] Furthermore, a drive motor is mounted on one side surface of each of the multiple sets of support plates.

[0010] Furthermore, the output end of the drive motor passes through the support plate and is connected to the active film feeding roller and the driven film feeding roller.

[0011] Furthermore, L-shaped plates are symmetrically mounted on the surface of the push plate, and a plug rod is slidably connected in the through hole opened on the surface of the L-shaped plate. The surface of the support plate is provided with a plurality of insertion holes adapted to the plug rod, and the plug rod is inserted into the insertion hole opened on the surface of the support plate.

[0012] Furthermore, a second reset spring is sleeved on the surface of the insertion rod. One end of the second reset spring is connected to the support plate, and the other end of the second reset spring is connected to the insertion rod.

[0013] The beneficial effects of this utility model are:

[0014] (I) This utility model, by setting up a processing table, first starts the drive motor on one side of the support plate when feeding the cotton seed film. The output of the drive motor drives the active and passive film feeding rollers to rotate. The active and passive film feeding rollers then feed the film. During the feeding process, the film slides inside the U-shaped clamp, which is fixed in position, thus stabilizing the position of the film during feeding. When dealing with film of different widths, the push plate is first pushed. The push plate then drives two pull rods to slide in the through holes on the support plate and the adjustment plate. During the sliding of the pull rods, the push plate squeezes the return spring, which deforms and resets the position of the pull rods, thereby resetting the position of the U-shaped clamp. This greatly improves the effectiveness of the device. The two pull rods drive the U-shaped clamp to slide between the two adjustment plates, allowing for position adjustment according to different widths of film, further improving the adaptability of the device and preventing positional deviation of different film during feeding.

[0015] (II) This utility model, by setting up a processing table, allows for the stabilization of packaging films of different widths. When adjusting the position of the U-shaped clamp, the insert rod on the L-shaped plate is first pulled. The insert rod slides within the through hole on the surface of the L-shaped plate. During the sliding process, the insert rod causes the second return spring to stretch. After the insert rod disengages from the insertion hole on the surface of the support plate, the operator pushes the push plate. After the position of the U-shaped clamp is adjusted, the operator releases the insert rod. The second return spring is no longer subjected to the stretching force and returns to its original shape, thereby causing the insert rod to re-insert into the insertion hole on the surface of the support plate. This achieves the fixation of the position of the U-shaped clamp and prevents the U-shaped clamp from shifting during film feeding, which could cause the packaging film to shift.

[0022] 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.

[0023] Please refer to Example 1 Figures 1-4This utility model provides a technical solution:

[0024] A film feeding mechanism for a cotton baler includes a processing table 1. Multiple sets of support plates 2 are symmetrically mounted on the surface of the processing table 1. One set of support plates 2 is symmetrically rotatably connected to an active film feeding roller 3. Two sets of support plates 2 are symmetrically rotatably connected to driven film feeding rollers 4. Adjusting plates 5 are symmetrically mounted between the two sets of driven film feeding rollers 4. A U-shaped clamping plate 6 is slidably connected between the two adjusting plates 5. A pull rod 7 is slidably connected within through holes on the surfaces of the support plates 2 and the adjusting plates 5. One end of each pull rod 7 passes through both the support plates 2 and the adjusting plates 5 and is connected to one side of the U-shaped clamping plate 6. A push plate 10 is mounted on the same end of both pull rods 7. A return spring 9 is sleeved on the surface of the pull rod 7. One end of the return spring 9 is connected to the push plate 10, and the other end of the return spring 9 is connected to the support plate 2.

[0025] Specifically, such as Figure 1 As shown, two tie rods 7 are symmetrically installed on the surface of the U-shaped clamping plate 6, and the two tie rods 7 are respectively installed on both sides of the U-shaped clamping plate 6. A drive motor 15 is installed on one side of the multiple sets of support plates 2. The output end of the drive motor 15 passes through the support plate 2 and is connected to the active film feeding roller 3 and the driven film feeding roller 4.

[0026] In this implementation scheme: A processing table 1 is provided. When feeding the cotton baling film, the drive motor 15 on one side of the support plate 2 is first activated. The output of the drive motor 15 drives the active film feeding roller 3 and the driven film feeding roller 4 to rotate. The active and driven film feeding rollers 3 and 4 then feed the baling film. During the feeding process, the baling film slides inside the U-shaped clamp 6. The position of the U-shaped clamp 6 is fixed, thus stabilizing the position of the baling film during feeding. When dealing with baling films of different widths, the push plate 10 is first pushed. The push plate 10 then drives two pull plates... Rod 7 slides within the through holes on the surfaces of support plate 2 and adjusting plate 5. During the sliding process of rod 7, push plate 10 compresses return spring 9, causing return spring 9 to deform. Return spring 9 can reset the position of rod 7, and thus reset the position of U-shaped clamp 6, greatly improving the effectiveness of the device. The two rods 7 drive U-shaped clamp 6 to slide between the two adjusting plates 5, thereby adjusting the position according to the width of the packing film, further improving the adaptability of the device and preventing positional deviation of different packing films during film feeding.

[0027] Please refer to Example 2 Figure 1 , Figure 2 and Figure 4The difference between this embodiment and embodiment 1 is that: an L-shaped plate 11 is symmetrically installed on the surface of the push plate 10, and a plug rod 12 is slidably connected in the through hole opened on the surface of the L-shaped plate 11. The surface of the support plate 2 is provided with a plurality of plug holes 13 that are adapted to the plug rod 12, and the plug rod 12 is inserted into the plug hole 13 opened on the surface of the support plate 2.

[0028] Specifically, such as Figure 1-4 As shown, a second reset spring 14 is sleeved on the surface of the insertion rod 12. One end of the second reset spring 14 is connected to the support plate 2, and the other end of the second reset spring 14 is connected to the insertion rod 12.

[0029] In this implementation plan: By setting up a processing table 1, when stabilizing the position of packaging films of different widths, when adjusting the position of the U-shaped clamping plate 6, the insertion rod 12 on the L-shaped plate 11 is first pulled. At this time, the insertion rod 12 slides in the through hole on the surface of the L-shaped plate 11. During the sliding process, the insertion rod 12 drives the second reset spring 14 to be stretched. After the insertion rod 12 is disengaged from the insertion hole 13 on the surface of the support plate 2, the worker pushes the push plate 10. After the position of the U-shaped clamping plate 6 is adjusted, the worker releases the insertion rod 12. The second reset spring 14 is no longer subjected to the stretching force. At this time, the second reset spring 14 returns to its shape, thereby driving the insertion rod 12 to re-insert into the insertion hole 13 on the surface of the support plate 2. This achieves the fixation of the position of the U-shaped clamping plate 6, avoiding the positional displacement of the U-shaped clamping plate 6 during the film feeding process, which could cause the packaging film to shift.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
