Description

Technical Field

[0001] This invention relates to the field of ABS plastic technology, and in particular to a production system and method for high-transparency ABS plastic granules. Background Technology

[0002] ABS plastic is a high-impact, high-heat-resistant, flame-retardant, reinforced, and transparent plastic. Its chemical name is acrylonitrile-butadiene-styrene copolymer. In the traditional preparation method, the plastic strip produced by the extruder needs to be cooled so that the plastic strip can be hardened quickly. Finally, the plastic strip is shredded by a plastic pelletizer to complete the production process of ABS plastic pellets.

[0003] Patent publication number CN 216181856 U discloses a plastic granule production line. A cooling box is located near the discharge end of the extruder and contains cooling water. A water-absorbing structure is installed in an inclined trough to adhere to and absorb the cooling water on the plastic strips. A dryer is located at the top of the inclined trough and is used to dry the plastic strips. According to this invention, the plastic strips are dried more thoroughly before being cut into granules, thereby improving the quality of the plastic granules.

[0004] The aforementioned patent has the following defects:

[0005] 1. The cooling water on the plastic strip is scraped off by the wiper blade. However, this simple scraping only removes some of the water from the surface of the plastic strip, leaving a large amount of water still stuck to it, resulting in an unsatisfactory water removal effect.

[0006] 2. The water absorption roller has a limited ability to absorb water from plastic strips. When it reaches saturation, its water absorption capacity is greatly reduced or even fails to absorb water. The service life of the water absorption roller is limited, and it needs to be replaced frequently in actual use. Summary of the Invention

[0007] In view of the problem that the existing technology has poor water removal effect on plastic rods, a production system and method for high-transparency ABS plastic granules is proposed.

[0008] One aspect of this application provides a production system for high-transparency ABS plastic pellets, the purpose of which is to provide a production system for high-transparency ABS plastic pellets.

[0009] The technical solution of the present invention is: a production system for high-transparency ABS plastic pellets, including a waterproof shell, and further including a water removal unit, a water absorption unit and an extrusion unit;

[0010] The dewatering unit is located inside the waterproof shell and is used to spin dry the water adhering to the plastic strip;

[0011] The water removal unit includes a drive assembly, a centrifugal assembly, and a transmission assembly. The centrifugal assembly is located inside the waterproof shell and is used to separate and filter water using multiple plastic strips.

[0012] The centrifugal assembly includes a filter cylinder, a partition, and a baffle cylinder. The filter cylinder and the baffle cylinder are fixedly connected by multiple partitions, and a plastic strip is accommodated between adjacent pairs of partitions.

[0013] The drive assembly is located on the top of the waterproof shell and serves as the driving force for the centrifugal assembly.

[0014] The transmission component is located on the outside of one end of the centrifugal component and is used to transmit power to the drive component.

[0015] The water absorption unit is located outside the centrifugal assembly and is used to absorb the water that is spun out.

[0016] The squeezing unit is located near the water absorption assembly and is used to squeeze the water absorbed by the water absorption unit.

[0017] The high-transparency ABS plastic pellet production system provided in this application embodiment, by setting up a dewatering unit, uses a drive component to drive a centrifugal component to rotate, and centrifugal force can be used to throw out the water from multiple plastic strips, thereby effectively removing the water from multiple plastic strips.

[0018] In one possible implementation of this application, the drive assembly includes a geared motor mounted on a waterproof housing, a drive wheel mounted on the output end of the geared motor, and a protective cover mounted on the top of the waterproof housing, with the protective cover located outside the drive wheel.

[0019] The high-transparency ABS plastic pellet production system provided in this application embodiment, by placing the geared motor on the top of the waterproof shell and then providing driving force to the centrifugal assembly through the drive wheel, can avoid affecting the feeding and unloading of plastic strips.

[0020] In one possible implementation of this application, the transmission assembly includes a driven wheel, and the driven wheel is meshed with the driving wheel.

[0021] In one possible implementation of this application, the front and rear ends of the waterproof shell are detachably connected to a cover plate by bolts and nuts. The cover plate is provided with an annular support groove. The front and rear ends of the filter cylinder are fixedly connected to a plurality of annularly distributed sliding columns, and the plurality of sliding columns slide on the inner wall of the support groove.

[0022] The high-transparency ABS plastic pellet production system provided in this application embodiment ensures that the filter cylinder, multiple partitions, and water baffle cylinder can rotate between two baffles by sliding the sliding column on the support groove, ultimately achieving the purpose of suspension, which is beneficial for the geared motor to drive the filter cylinder to rotate.

[0023] In one possible implementation of this application, the water-absorbing unit includes a plurality of absorbent cottons distributed around the waterproof shell, the plurality of absorbent cottons being in contact with each other, and the squeezing unit includes a camshaft disposed between two baffles, a squeezing plate disposed on one side of the camshaft, a grid assembly disposed on one side of the absorbent cottons, and rotating shafts disposed at both ends of the camshaft, and the camshaft, squeezing plate, absorbent cottons and grid assembly abutting against each other.

[0024] The high-transparency ABS plastic pellet production system provided in this application embodiment, by setting up water-absorbing cotton, can not only effectively prevent the water that is shaken out from splashing onto the inner wall of the waterproof shell and then rebounding onto the plastic strip, but also absorb the water that is shaken out, saving the subsequent water cleaning and collection work.

[0025] In one possible implementation of this application, the transmission assembly further includes a first pulley disposed on the drive wheel, a second pulley disposed on the camshaft, and a transmission belt disposed on the first pulley and the second pulley, wherein the first pulley and the second pulley are connected to the transmission belt in a transmission manner.

[0026] The high-transparency ABS plastic pellet production system provided in this application embodiment has a transmission belt wound around a first pulley and three second pulleys respectively. The first pulley drives the transmission belt to move, thereby causing the three second pulleys to rotate.

[0027] In one possible implementation of this application, the grid assembly includes a pull rope disposed outside the camshaft, a plurality of telescopic components and a rolling roller disposed between any two adjacent telescopic components, and both ends of the pull rope pass through the extrusion plate and absorbent cotton and are fixedly connected to the outside of the telescopic components.

[0028] The high-transparency ABS plastic pellet production system provided in this application embodiment uses a pull rope wrapped around the outside of the camshaft, which is repeatedly pulled by the rotating camshaft, thereby helping the telescopic component to perform telescopic movement.

[0029] In one possible implementation of this application, the telescopic component includes an outer rod disposed on one side of the absorbent cotton, an inner rod disposed inside the outer rod, a reset elastic member disposed between the inner bottom of the outer rod and the bottom of the inner rod, and one end of the pull rope is connected to the rod wall of the outer rod, and the other end is connected to the outer wall of the inner rod.

[0030] The high-transparency ABS plastic pellet production system provided in this application embodiment has an inner rod that retracts towards the inside of the outer rod under the pull of the traction rope, and can then return to its original position with the help of a reset elastic element, thereby achieving the purpose of reciprocating extension and retraction of the telescopic component.

[0031] In one possible implementation of this application, limiting grooves are provided on one side of each of the two shields facing each other, and multiple limiting posts are provided at the outer ends of the outer rod and the inner rod, and the limiting posts slide up and down within the limiting grooves.

[0032] The high-transparency ABS plastic pellet production system provided in this application embodiment has a limiting groove on one side of each of the two shields, and multiple limiting posts are provided at the outer end of the telescopic component, and the limiting posts slide up and down in the groove.

[0033] Another aspect of this application provides a method for producing high-transparency ABS plastic granules, the purpose of which is to provide a method for producing high-transparency ABS plastic granules.

[0034] The technical solution of this invention is: a method for producing high-transparency ABS plastic granules, comprising the following steps:

[0035] S1: The plastic strips are placed between the partitions one by one by the conveyor belt until the filling is complete.

[0036] First, adjust the geared motor to a slow speed, and then turn it on intermittently to fill each pair of partitions with multiple plastic strips, thus completing the filling process.

[0037] S2: Turn on the geared motor to make it rotate the centrifugal assembly quickly to complete the water removal work.

[0038] Adjust the geared motor to high speed mode, and use centrifugal force to quickly throw off the water on the surface of the plastic strip, so that a large amount of water is removed from the plastic strip, effectively completing the water removal work of the plastic strip.

[0039] S3: The water splashed out in S2 splashes onto the absorbent cotton, completing the water collection process;

[0040] As the filter cylinder rotates, the water on the plastic strip is flung out and falls onto the four absorbent cotton balls. Because the absorbent cotton balls are in contact with each other, the moisture can be transferred between them. The absorbent cotton balls also have a buffering effect, which can effectively prevent the water from being bounced back onto the plastic strip.

[0041] S4: The transmission assembly drives the camshaft to rotate, causing it to repeatedly squeeze the absorbent cotton with the extrusion plate, thus completing the water squeezing work on one side of the absorbent cotton.

[0042] The geared motor drives the drive wheel to rotate, which in turn drives the first pulley to move the conveyor belt, which in turn drives the three second pulleys to rotate. Finally, it drives the three sets of water-squeezing components to move, so that the absorbent cotton on the left and right sides and the bottom is squeezed by the squeezing plate to squeeze out the absorbed water, thus achieving the dehydration of the absorbent cotton and effectively ensuring that the absorbent cotton can maintain its absorbent state for a long time. This is the first stage of water squeezing.

[0043] S5: During the rotation of the camshaft, the telescopic components also retract, and the squeezing rollers complete the water squeezing work on the other side of the absorbent cotton.

[0044] The method for producing high-transparency ABS plastic pellets provided in this application embodiment can also repeatedly pull the traction rope. By limiting the telescopic component, it is forced to cooperate with the elastic reset component to perform telescopic movement after being pulled by the traction rope. This can drive multiple pressing rollers to move, so that the multiple pressing rollers squeeze the other side of the absorbent cotton, and finally complete the dehydration work on the other side of the absorbent cotton.

[0045] The beneficial effects of this invention are:

[0046] 1. By setting up partitions and filter cylinders, multiple plastic strips can be separated, effectively preventing water from sticking between the plastic strips. Then, the centrifugal force generated by the geared motor is used to quickly throw off the water on the surface of the plastic strips, so that a large amount of water on the surface of the plastic strips is removed, effectively completing the water removal work of the plastic strips.

[0047] 2. By setting up absorbent cotton, on the one hand, during the rotation of the filter cylinder, the water on the plastic strip is thrown out and falls onto the four absorbent cottons, where it is absorbed. Since the multiple absorbent cottons are in contact with each other, the humidity can be transferred between them. On the other hand, the structural characteristics of the absorbent cotton itself can effectively buffer the water thrown out, effectively preventing water from splashing everywhere, or even splashing onto the outside of the waterproof shell, making it difficult to collect water later.

[0048] 3. By setting up a squeezing unit and using a geared motor, the unit drives three camshafts to rotate via a transmission assembly. The rotation of the camshafts drives the squeezing plate to move, causing the absorbent cotton to be squeezed out of water, thus achieving dehydration of one side of the absorbent cotton. On the other hand, the pull rope can be repeatedly pulled. By limiting the telescopic component, it is forced to move in conjunction with the elastic reset component after being pulled by the pull rope. This causes multiple pressing rollers to move, squeezing the other side of the absorbent cotton, ultimately completing the dehydration of the other side of the absorbent cotton.

[0063] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0064] Example 1, referring to Figure 1 , Figure 4 The first embodiment of the present invention provides a production system for high-transparency ABS plastic pellets, including a waterproof shell 1, a water removal unit 2, a water absorption unit 3 and an extrusion unit 4;

[0065] The water removal unit 2 is located inside the waterproof shell 1 and is used to spin dry the water adhering to the plastic strip;

[0066] Reference Figure 3 The water removal unit 2 includes a drive assembly 21, a centrifugal assembly 22 and a transmission assembly 23. The centrifugal assembly 22 includes a filter cylinder 221, a partition 222 and a baffle cylinder 223. The partition 222 is made of waterproof material. The filter cylinder 221 and the baffle cylinder 223 are fixedly connected by multiple partitions 222. A plastic strip is accommodated between adjacent pairs of partitions 222.

[0067] Multiple plastic strips are sequentially conveyed by a conveyor belt into the cavity between each pair of partitions 222.

[0068] The drive assembly 21 is located on the top of the waterproof housing 1 and serves as the driving force for the centrifugal assembly 22;

[0069] The transmission component 23 is located on the outside of one end of the centrifugal component 22 and is used to transmit power to the drive component 21.

[0070] The water absorption unit 3 is located outside the centrifugal assembly 22 and is used to absorb the water that is spun out.

[0071] The squeezing unit 4 is located near the water absorption unit 3 and is used to squeeze the water absorbed by the water absorption unit 3.

[0072] By setting up a water removal unit 2, the centrifugal component 22 is rotated by the drive component 21, and the water on multiple plastic strips can be thrown out by centrifugal force, thereby effectively removing the water from multiple plastic strips.

[0073] Reference Figure 2 and Figure 3 The drive assembly 21 includes a geared motor 211 mounted on the waterproof housing 1, a drive wheel 212 mounted on the output end of the geared motor 211, and a protective cover 213 mounted on the top of the waterproof housing 1, with the protective cover 213 located outside the drive wheel 212.

[0074] Specifically, the geared motor 211 is fixedly connected to the top of the waterproof housing 1, the output end of the geared motor 211 is directly fixedly connected to the drive wheel 212, and the protective cover 213 is fixedly connected to the top of the waterproof housing 1.

[0075] By setting the geared motor 211 on the top of the waterproof housing 1 and then providing driving force to the centrifugal assembly 22 through the drive wheel 212, the feeding and unloading of the plastic strips can be carried out without affecting them.

[0076] Reference Figure 3 The transmission assembly 23 includes a driven wheel 231, which is meshed with the driving wheel 212.

[0077] Since the driven wheel 231 and the driving wheel 212 are engaged, when the geared motor 211 is turned on, the driving wheel 212 and the driven wheel 231 can drive the geared motor 211, which is equipped with a speed adjustment button, to adjust to a slow speed when it is necessary to fill plastic strips, and then intermittently start the geared motor 211 to ensure that multiple plastic strips can be safely filled into the cavity between each partition 222 in sequence.

[0078] Reference Figure 2 The front and rear ends of the waterproof shell 1 are detachably connected to a cover plate 5 by bolts and nuts. The cover plate 5 has an annular support groove 51. The front and rear ends of the filter cylinder 221 are fixedly connected to multiple evenly distributed annular sliding columns, which slide on the inner wall of the support groove 51.

[0079] The filter cylinder 221, multiple partitions 222 and water baffle 223 are connected as a whole. Multiple sliding columns are set at the front and rear ends of the filter cylinder 221. By sliding the sliding columns on the support groove 51, it can be ensured that the filter cylinder 221, multiple partitions 222 and water baffle 223 can rotate between the two baffles 5, and finally achieve the purpose of suspension, which is conducive to the reduction motor 211 driving the filter cylinder 221 to rotate.

[0080] The process is divided into two parts. The first step is filling: first, adjust the speed reduction motor 211 to a slow speed, and then turn it on intermittently to fill multiple plastic strips into each pair of partitions 222 to complete the filling work. The second step is dewatering: adjust the speed reduction motor 211 to a fast speed, and use centrifugal force to quickly throw off the water on the surface of the plastic strips, so that a large amount of water on the surface of the plastic strips is removed, effectively completing the dewatering work of the plastic strips.

[0081] Example 2, refer to Figure 4-7 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: the water-absorbing unit 3 includes multiple absorbent cottons 31 distributed around the waterproof shell 1. The multiple absorbent cottons 31 are in contact with each other to achieve humidity transfer between the absorbent cottons 31. Both sides of the absorbent cottons 31 are fixedly connected to the inner wall of the waterproof shell 1. The squeezing unit 4 includes a camshaft 41 disposed between two baffles 5, a squeezing plate 42 disposed on one side of the camshaft 41, a grid assembly 43 disposed on one side of the absorbent cottons 31, the two ends of the grid assembly 43 are fixedly connected to the outer side of the absorbent cottons 31, the middle part abuts against the absorbent cottons 31, and a rotating shaft disposed at both ends of the camshaft 41. The camshaft 41 rotates between the two baffles 5 through the rotating shaft, and the camshaft 41, the squeezing plate 42, the absorbent cottons 31 and the grid plate abut against each other.

[0082] By setting up the absorbent cotton 31, on the one hand, it effectively prevents the water that is thrown out from splashing onto the inner wall of the waterproof shell 1 and then rebounding onto the plastic strip, causing the water to return to the plastic strip, thereby increasing the working time of the reduction motor 211 and reducing the water removal efficiency of the device; on the other hand, it can absorb the water that is thrown out, effectively preventing the water from being difficult to collect and saving the subsequent water cleaning and collection work.

[0083] Specifically, a water collection tank can be installed at the bottom of the waterproof shell 1 to collect the water that falls into the bottom of the waterproof shell 1, so that it is not necessary to scrape off the water from the inner wall of the waterproof shell 1 later.

[0084] Specifically, the squeezing plate 42 is wrapped inside the absorbent cotton 31. When the camshaft 41 rotates, since the distance from the outer arc of the camshaft 41 to the center is not unique, the rotation of the camshaft 41 will cause the squeezing plate 42 to reciprocate. Each time the squeezing plate 42 pushes the absorbent cotton 31, it will squeeze the water on the surface of the absorbent cotton 31, thereby achieving the dehydration of the absorbent cotton 31 and effectively ensuring that the absorbent cotton 31 can maintain its absorbent state for a long time.

[0085] Specifically, refer to Figure 4 The transmission assembly 23 also includes a first pulley 232 fixedly connected to the drive pulley 212, a second pulley 233 fixedly connected to the camshaft 41, and a transmission belt 234 wound around the first pulley 232 and the second pulley 233, and the first pulley 232 and the second pulley 233 are connected to the transmission belt 234.

[0086] During use, three sets of extrusion units 4 can be set up, respectively on the left and right sides and below the filter cylinder. Therefore, there are three second pulleys 233. The first pulley 232 is located on the concentric shaft of the drive pulley 212, and the second pulleys 233 are located on the concentric shaft of the camshaft 41. The transmission belt 234 is respectively wound around the first pulley 232 and the three second pulleys 233. The first pulley 232 drives the transmission belt 234 to move, thereby driving the three second pulleys 233 to rotate.

[0087] In actual operation, the radius of the second pulley 233 can be set to be larger than the radius of the first pulley 232, with a ratio of 2:1 or 3:1, so as to achieve the purpose of speed reduction transmission.

[0088] Specifically, to avoid the transmission belt 234 interfering with the discharge of the plastic strip, a pair of tension pulleys can be installed. The tension pulleys can not only prevent the transmission belt 234 from being too loose, resulting in low transmission efficiency and difficulty in driving the three pulleys to rotate, but also spread the transmission belt 234, which is beneficial for the unloading of the plastic strip.

[0089] The working process of this embodiment can be divided into three steps: water removal process, water absorption process, and water squeezing process.

[0090] The water removal process has been clearly described in Example 1 and will not be described again here;

[0091] Water absorption process: Specifically, there are four absorbent cottons 31. During the rotation of the filter cylinder 221, the water on the plastic strip is thrown out and falls onto the four absorbent cottons 31 respectively. Since the multiple absorbent cottons 31 are in contact with each other, the humidity can be transferred between the absorbent cottons 31.

[0092] Dehydration process: The geared motor 211 drives the drive wheel 212 to rotate, which in turn drives the first pulley 232 to move the conveyor belt, which in turn drives the three second pulleys 233 to rotate, and finally drives the three sets of dehydration components to move, so that the absorbent cotton 31 on the left and right sides and the bottom is squeezed by the squeezing plate 42 to squeeze out the absorbed water, thereby achieving the dehydration of the absorbent cotton 31 and effectively ensuring that the absorbent cotton 31 can maintain its absorbent state for a long time.

[0093] The remaining structure is the same as that in Example 1.

[0094] Example 3, referring to Figure 8-12 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the grid assembly 43 includes a pull rope 431 disposed outside the camshaft 41, and also includes a plurality of telescopic components 432 and a rolling roller 433 disposed between any two adjacent telescopic components 432. Both ends of the pull rope 431 pass through the extrusion plate 42 and the absorbent cotton 31 and are fixedly connected to the outside of the telescopic component 432.

[0095] Specifically, a telescopic tube can be installed on the inner wall of the waterproof shell 1, and the telescopic tube is connected to the extrusion plate 42, so that the telescopic tube bears the entire weight of the extrusion plate 42.

[0096] Since the camshaft 41 is equivalent to an eccentric wheel, the distance from the outer wall to the center of the drive circle will change during the rotation. The pull rope 431 wrapped around the outside of the camshaft 41 is repeatedly pulled by the rotating camshaft 41, which can help the telescopic component 432 to perform telescopic movement.

[0097] Reference Figure 9-10 The telescopic component 432 includes an outer rod 4321 disposed on one side of the absorbent cotton 31, an inner rod 4322 sliding inside the outer rod 4321, and a reset elastic element 4323 disposed between the inner bottom of the outer rod 4321 and the bottom of the inner rod 4322. One end of the pull rope 431 is connected to the rod wall of the outer rod 4321, and the other end is connected to the outer wall of the inner rod 4322.

[0098] Specifically, the reset elastic element 4323 can also be a spring.

[0099] When the inner rod 4322 is pulled by the traction rope 431, it retracts towards the inside of the outer rod 4321. Subsequently, it can return to its original position with the help of the reset elastic element 4323, thereby realizing the purpose of reciprocating extension and retraction of the telescopic component 432.

[0100] Reference Figure 11-12 Each of the two cover plates 5 has a limiting groove 52 on one side facing each other, and the outer end of the telescopic component 432 is provided with multiple limiting posts 53, which slide up and down in the groove.

[0101] The limiting post 53 can only slide along the inner wall of the limiting groove 52 under the limiting position of the limiting groove 52. When the pulling rope 431 provides a vertical traction force to the telescopic component 432, the telescopic component 432 will be forced to telescopically move under the action of the limiting post 53.

[0102] Compared to Example 1, the usage process adds a dewatering step: Start the reduction motor 211, which drives the three camshafts 41 to rotate through the transmission assembly 23. The rotation of the camshafts 41 drives the extrusion plate 42 to move, so that the absorbent cotton 31 is squeezed out of water by the extrusion plate 42, thus achieving the dewatering of one side of the absorbent cotton 31. On the other hand, the pull rope 431 can be pulled repeatedly. By limiting the telescopic component 432, it is forced to move in conjunction with the elastic reset component after being pulled by the pull rope 431. This can drive the multiple pressing rollers 433 to move, so that the multiple pressing rollers 433 squeeze the other side of the absorbent cotton 31, and finally complete the dewatering of the other side of the absorbent cotton 31.

[0103] The remaining structure is the same as that in Example 2.

[0104] Example 4, refer to Figure 1-12 The fourth embodiment of the present invention provides a method for producing high-transparency ABS plastic granules, comprising the following steps:

[0105] Preliminary steps: First, heated plastic is injected into the mold cavity, and then multiple plastic strips are produced by the extruder. The produced plastic strips fall into the cooling water. After a period of time, they are taken out and placed on the conveyor belt.

[0106] S1: The plastic strips are placed between the partitions 222 sequentially by the conveyor belt until the filling is complete;

[0107] First, adjust the geared motor 211 to a slow speed, and then intermittently turn it on to fill multiple plastic strips into each pair of partitions 222, thus completing the filling work.

[0108] S2: Turn on the geared motor 211 to make it rotate the centrifugal assembly 22 quickly to complete the water removal work;

[0109] Adjusting the geared motor 211 to high speed mode allows centrifugal force to quickly remove moisture from the surface of the plastic strip, effectively removing a large amount of water from the plastic strip.

[0110] S3: The water splashed out in S2 splashes onto the absorbent cotton 31, completing the water collection work;

[0111] During the rotation of the filter cylinder 221, the water on the plastic strip is thrown out and falls onto the four absorbent cottons 31. Since the multiple absorbent cottons 31 are in contact with each other, the humidity can be transferred between the absorbent cottons 31. The absorbent cottons 31 also have a buffering effect, which can effectively prevent the water from being bounced back onto the plastic strip.

[0112] S4: The transmission assembly 23 drives the camshaft 41 to rotate, causing it to repeatedly squeeze the absorbent cotton 31 with the extrusion plate 42, thus completing the water squeezing work on one side of the absorbent cotton 31.

[0113] The geared motor 211 drives the drive wheel 212 to rotate, which in turn drives the first pulley 232 to move the conveyor belt, which in turn drives the three second pulleys 233 to rotate. Finally, it drives the three sets of water-squeezing components to move, so that the absorbent cotton 31 on the left and right sides and the bottom is squeezed by the squeezing plate 42 to squeeze out the absorbed water, thereby achieving the dehydration of the absorbent cotton 31 and effectively ensuring that the absorbent cotton 31 can maintain a water-absorbing state for a long time. This is the first stage of water squeezing.

[0114] S5: During the rotation of the camshaft 41, the telescopic component 432 also retracts, and the water squeezing work on the other side of the absorbent cotton 31 is completed by the pressing roller 433.

[0115] By repeatedly pulling the traction rope 431, the telescopic component 432 is limited and forced to move in conjunction with the elastic reset component after being pulled by the traction rope 431. This causes multiple pressing rollers 433 to move, squeezing the other side of the absorbent cotton 31, and finally completing the dehydration work on the other side of the absorbent cotton 31.
