Description
Technical Field
[0001] This utility model relates to the field of recycled cotton yarn technology, specifically a recycled cotton yarn cutting device with dust removal function. Background Technology
[0002] Recycled cotton yarn refers to cotton yarn that is spun from waste cotton textiles (such as old clothes, textile mill scraps, and fabric edges) as raw materials, after a series of physical treatments including recycling, sorting, crushing, opening, impurity removal, and reprocessing. Recycled cotton yarn cutting equipment is a special mechanical device used to cut recycled cotton yarn into specific lengths or to break it to a fixed length. It is essentially a key link in the textile waste recycling and processing line, aiming to transform irregular and continuous recycled yarn raw materials into short fibers or fixed-length segments of uniform specifications for subsequent reprocessing and utilization. For existing recycled cotton yarn cutting devices, since recycled cotton yarn itself contains a large number of short fibers and dust left over from the processing, fiber breakage during cutting will generate new flying lint and dust, which seriously pollutes the working environment, endangers the respiratory health of operators, and poses a potential risk of dust explosion, thus causing inconvenience to people. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a recycled cotton yarn cutting device with dust removal function. This solves the problem that existing recycled cotton yarn cutting devices, due to the presence of a large number of short fibers and residual dust from the processing of recycled cotton yarn, generate new flying lint and dust during cutting, which seriously pollutes the working environment, endangers the respiratory health of operators, and poses a potential risk of dust explosion, thus causing inconvenience to users.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a recycled cotton yarn cutting device with dust removal function, comprising a base plate, a collection box fixedly connected to the top of the base plate, a filter screen plate fixedly connected to the inner wall of the collection box, a fan fixedly connected to one side of the inner wall of the collection box, a duct connected to the output end of the fan, and one side of the outer wall of the duct penetrating one side of the collection box, an air guide hopper connected to the top of the collection box, a vertical plate fixedly connected to the top of the base plate, a first electric push rod fixedly connected to the upper part of the outer wall of the vertical plate, a horizontal plate fixedly connected to the output end of the first electric push rod, a cutting blade fixedly connected to the bottom of the horizontal plate, and a cutting table fixedly connected to the top of the base plate below the cutting blade.
[0005] Preferably, the top of the base plate is rotatably connected to a plurality of first guide rollers via bearings, and the lower sides of the front of the vertical plate are rotatably connected to second guide rollers via bearings.

[0013] 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.
[0014] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0015] For existing recycled cotton yarn cutting devices, since recycled cotton yarn itself contains a large number of short fibers and dust left over from the processing, fiber breakage during cutting will generate new flying lint and dust, which seriously pollutes the working environment, endangers the respiratory health of operators, and has the potential risk of dust explosion, thus causing inconvenience to people's use. In view of this, the present invention provides a recycled cotton yarn cutting device with dust removal function. Through the cooperation of the base plate, collection box, fan, duct and air guide bucket, the dust generated during cutting can be automatically collected to prevent the dust from spreading into the surrounding air, thereby effectively ensuring the quality of the surrounding air environment, ensuring the respiratory health of the operators, and avoiding the danger of dust explosion at the source, thus making it convenient for people to use.
[0016] Example 1: By Figure 1 , 2As shown in section 4, a recycled cotton yarn cutting device with dust removal function includes a base plate 1, a collection box 2 fixedly connected to the top of the base plate 1, a filter plate 22 fixedly connected to the inner wall of the collection box 2, a fan 3 fixedly connected to one side of the inner wall of the collection box 2, a duct 4 connected to the output end of the fan 3, and one side of the outer wall of the duct 4 penetrating one side of the collection box 2, an air guide hopper 5 connected to the top of the collection box 2, a vertical plate 14 fixedly connected to the top of the base plate 1, a first electric push rod 15 fixedly connected to the upper part of the outer wall of the vertical plate 14, a horizontal plate 23 fixedly connected to the output end of the first electric push rod 15, a cutting blade 20 fixedly connected to the bottom of the horizontal plate 23, and a cutting table 18 fixedly connected to the top of the base plate 1 below the cutting blade 20. In the specific implementation process, it is worth noting that there are no restrictions on the models of the blower 3 and the first electric push rod 15, as long as they meet the usage requirements. The blower 3 can extract the air from the inside of the collection box 2, and then through the negative pressure effect, the dust generated during cutting can follow the airflow and enter the inside of the collection box 2 through the air guide hopper 5. The first electric push rod 15 can change the position and height of the cutting blade 20 so that the cotton yarn can be cut by the cutting blade 20. There are no restrictions on the mesh count of the filter plate 22, which can be selected according to the actual use. It should be noted that the staff needs to disassemble and clean the filter plate 22 regularly to avoid the filter plate 22 from becoming clogged, which would affect the quality of use and work efficiency. Furthermore, the top of the base plate 1 is rotatably connected to multiple first guide rollers 6 via bearings, and the lower sides of both sides of the front of the vertical plate 14 are rotatably connected to second guide rollers 13 via bearings. In the specific implementation process, it is worth noting that the first guide roller 6 and the second guide roller 13 can guide the cotton yarn; Specifically, when using the recycled cotton yarn cutting device with dust removal function, during cutting, the fan 3 discharges the air inside the collection box 2 through the duct 4. At this time, the air pressure inside the collection box 2 decreases, and then through the negative pressure effect, the dust generated during cutting can follow the airflow into the interior of the collection box 2 to complete the dust collection work.
[0017] Example 2: From Figure 1 and 2 It can be seen that rubber pads 19 are fixedly connected to both sides of the top of the cutting table 18, pressure plates 16 are inserted into both sides of the inner wall of the horizontal plate 23, and two springs 17 are fixedly connected to the top of the outer wall of the two pressure plates 16, and the bottom of the multiple springs 17 are fixedly connected to the top of the horizontal plate 23. In the specific implementation process, it is worth noting that when the spring 17 is stretched, it will exert a downward force on the pressure plate 16 so as to press and tighten the cotton yarn through the rubber pad 19. Specifically, based on the above embodiment one, when cutting, when the pressure plate 16 presses the cotton yarn, the spring 17 begins to stretch. At this time, due to the elastic potential energy of the spring 17, it can continuously exert a downward force on the pressure plate 16, and thus the cotton yarn can be pressed and tightened through the cooperation of the pressure plate 16 and the rubber pad 19.
[0018] Example 3: From Figure 1 and 3 It can be seen that a support plate 8 is fixedly connected to the inner wall of the base plate 1, a second electric push rod 9 is fixedly connected to the outer wall of the support plate 8, a slider 11 is fixedly connected to the output end of the second electric push rod 9, a pressing roller 10 is rotatably connected to the inner wall of the slider 11 through a bearing, a pressure sensor 12 is fixedly connected to the outer wall of the pressing roller 10, a support plate 21 is fixedly connected to the outer wall of the pressure sensor 12, and the bottom of the support plate 21 is fixedly connected to the top of the slider 11. In the specific implementation process, it is worth noting that there are no restrictions on the model of the second electric push rod 9 and the pressure sensor 12, as long as they meet the usage requirements. The pressure sensor 12 can detect the tension of the cotton yarn. When it is not within the appropriate range (the specific value range can be selected according to the actual usage), the position of the tension roller 10 can be changed by the second electric push rod 9, thereby adjusting the tension. Furthermore, a controller 7 is fixedly connected to the top of the base plate 1, and the controller 7 is electrically connected to the pressure sensor 12 and the second electric push rod 9. In the specific implementation process, it is worth noting that the model of controller 7 is not limited, as long as it meets the usage requirements. Pressure sensor 12 can transmit detection information to controller 7. When it is not within the appropriate range, controller 7 can control the second electric push rod 9 to make adjustments. Specifically, based on the above embodiment one, during operation, the pressure sensor 12 can detect the tension of the cotton yarn and then send the detection signal to the controller 7. When the cotton yarn is not in the optimal tension state, the controller 7 can activate the second electric push rod 9, which can drive the slider 11 to slide along the inner wall of the base plate 1. The tension can then be changed by adjusting the position of the tension roller 10.
[0019] 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.
