Description

Technical Field

[0001] The invention relates to the technical field of extruders, and in particular to an extruder for producing anti-aging ground films. Background Art

[0002] Ground film is ground covering film, usually transparent or black PE film, but also green and silver film. It is used for agricultural ground covering. The raw materials are heated and melted by an extruder and extruded from the die head, and then formed by a film blowing machine. It has certain anti-aging ability.

[0003] In order to filter out infusible impurities in the raw materials and prevent the extrusion port from being blocked, a filter is installed between the extruder and the extrusion head. However, after the extruder has been working for a period of time, the filter holes on the filter are blocked over a large area. If it is not replaced, not only will normal production be impossible, but the equipment will also be damaged due to excessive pressure in the material pipe. However, the machine needs to be shut down to clean the filter, which greatly reduces production efficiency. Summary of the invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art and to propose an extruder for producing anti-aging mulch film.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Reference Figure 1-Figure 4 An extruder for producing aging-resistant ground film includes a control box 1, the upper end of the control box 1 is fixedly connected to a body 2 through a bracket, the inner wall of the body 2 is rotatably connected to a first rod 3, the side wall of the first rod 3 is fixedly connected to a spiral conveying blade 4, and the top of the body 2 is fixedly connected to a feeding box 5.

[0022] The extrusion mechanism includes a circular plate 6 which is rotatably connected to the side wall of the machine body 2 through a rotating shaft seal. Two grooves 7 are provided on the side wall of the circular plate 6. A filter plate 8 is tightly fitted on the inner wall of the groove 7. An extrusion tube 10 is fixedly connected to the side wall of the control box 1 through an L-shaped plate 14. The side wall of the extrusion tube 10 is rotatably connected to the side wall of the circular plate 6 in a sealed manner. The side wall of the extrusion tube 10 away from the circular plate 6 is fixedly connected to an extrusion head 11. The filter plate 8 can filter infusible impurities in the raw material to prevent the extrusion head 11 from being blocked.

[0023] A second discharge port 13 is formed on the inner wall of the groove 7 and is in contact with the side wall of the extrusion tube 10. A first discharge port 12 corresponding to one of the second discharge ports 13 is formed on the inner wall of the extrusion tube 10. A feed port 27 is formed on the inner wall of the two grooves 7 close to the body 2. A discharge port 9 corresponding to one of the feed ports 27 is formed on the inner wall of the body 2 away from the feeding box 5.

[0024] A cover plate 15 is tightly fitted on the inner wall of the groove 7 , and the side wall of the cover plate 15 is fixedly connected to the side wall of the filter plate 8 , and the side wall of the cover plate 15 is fixedly connected to the side wall of the circular plate 6 via a plurality of bolts 16 .

[0025] An annular groove 17 is formed on the side wall of the circular plate 6 close to the body 2, and a gear ring 18 is fixedly connected to the inner wall of the annular groove 17. A second rod 19 is rotatably connected to the inner wall of the control box 1. One end of the second rod 19 is located in the annular groove 17 and is fixedly connected to a gear 20. The side wall of the gear 20 is meshed with the side wall of the gear ring 18.

[0026] A motor 21 is fixedly connected to the inner wall of the control box 1, a first wheel 22 is fixedly connected to the movable end of the motor 21, a second wheel 23 is fixedly connected to one end of the first rod 3 close to the feeding box 5, and a synchronous belt is connected between the first wheel 22 and the second wheel 23.

[0027] The motor 21 is provided with a rotating mechanism for driving the second rod 19 to rotate, and the rotating mechanism includes a one-way bearing 24. The inner ring side wall of the one-way bearing 24 is fixedly connected to the side wall of the movable shaft of the motor 21, and the outer ring side wall of the one-way bearing 24 is fixedly connected to the third wheel 25. The end of the second rod 19 away from the gear 20 is fixedly connected to the fourth wheel 26, and a synchronous belt is connected between the third wheel 25 and the fourth wheel 26.

[0028] It should be noted that when the motor 21 rotates clockwise, the inner ring of the one-way bearing 24 does not drive its outer ring to rotate. At this time, the motor 21 will drive the first rod 3 to rotate clockwise through the first wheel 22, the synchronous belt and the second wheel 23. At this time, the spiral conveying blade 4 rotates clockwise to heat the raw material and transport it out. When the motor 21 rotates counterclockwise, the inner ring of the one-way bearing 24 drives its outer ring to rotate, and then the motor 21 drives the first rod 3 to rotate counterclockwise through the third wheel 25, the synchronous belt and the fourth wheel 26. The gear 20 can drive the gear ring 18 to rotate, and then drive the circular plate 6 to rotate, and replace the positions of the two grooves 7.

[0029] When the anti-aging mulch film is produced, the raw materials required for the anti-aging mulch film are first added to the feeding box 5, and then the motor 21 is driven to rotate clockwise. At this time, the motor 21 drives the first rod 3 to rotate clockwise through the first wheel 22, the synchronous belt and the second wheel 23, and drives the spiral conveying blade 4 to rotate clockwise to heat the raw materials and convey them out. Then the raw materials will enter the groove 7 opposite to the discharge port 9 through the discharge port 9 and the feed port 27;

[0030] Afterwards, the molten raw material is filtered through the filter plate 8 and then flows out of the extrusion head 11 through the second discharge port 13, the first discharge port 12 and the extrusion tube 10. At this time, the filter plate 8 can filter the infusible impurities in the raw material to prevent the extrusion head 11 from being blocked.

[0031] When the filter plate 8 in the groove 7 facing the discharge port 9 is blocked, the driving motor 21 rotates half a circle counterclockwise, and the inner ring of the one-way bearing 24 drives its outer ring to rotate, and then the motor 21 drives the first rod 3 to rotate counterclockwise through the third wheel 25, the synchronous belt and the fourth wheel 26, and the gear 20 can drive the gear ring 18 to rotate, and then drive the circular plate 6 to rotate half a circle, and the positions of the two grooves 7 are replaced. Then, the feed port 27 in the replaced groove 7 is opposite to the discharge port 9, and the second discharge port 13 is opposite to the first discharge port 12, and the molten raw material can continue to be extruded, avoiding the need to stop the machine when cleaning the filter screen in the prior art, which greatly reduces the production efficiency;

[0032] After the clogged filter plate 8 is rotated away from the discharge port 9, the two bolts 16 near the filter plate 8 are removed, and then the filter plate 8 is taken out from the groove 7 through the cover plate 15 and cleaned.

[0033] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
