Description

Technical Field

[0001] This utility model relates to the field of roving end removal technology, specifically a tail yarn machine removal device. Background Technology

[0002] In the roving process of the textile industry, a large number of roving ends are generated during yarn changing, yarn breakage, and yarn doffing. If these roving ends are not removed in time, they will not only accumulate around the equipment and pollute the production environment, but also waste high-quality cotton fibers and increase production costs. Currently, the commonly used yarn end removal devices in the industry mostly adopt a structure of a single fan and a single suction pipe. However, the negative pressure of a single fan is limited. When multiple roving ends need to be processed, the negative pressure will be dispersed in the suction pipe, resulting in some roving ends not being completely adsorbed or not fully opened. Unopened roving ends cannot be reused, still causing fiber waste. In addition, the filtration structure of most devices only uses a single-stage filter screen, which can only intercept large-sized impurities. Lightweight short fibers cannot be effectively separated, resulting in a high content of short fibers in the recycled fibers, which affects the quality of subsequent spinning.

[0003] Existing publicly available technical solution CN204588308U discloses an integrated roving tail yarn removal machine, including an installation platform, a rotating device, and a lifting device. The installation platform is equipped with a set of yarn tube shafts, each driven to rotate by a rotary motor of the rotating device via a rotary transmission mechanism. The lifting device is equipped with a lifting motor, which drives the installation platform to move up and down via a lifting transmission mechanism. This design is used to solve the problem of incomplete yarn unwinding. This invention uses a single rotary motor to drive multiple yarn tube shafts to rotate via a rotary transmission mechanism; a single lifting motor to drive the installation platform to move up and down via a lifting transmission mechanism; and a cylinder to push a suction nozzle mounting frame equipped with multiple suction nozzles towards or away from the yarn tail tubes. This structure greatly simplifies the mechanical setup of the integrated roving tail yarn removal machine, reduces the number of parts used, thus simplifying pneumatic and electrical control, improving operational reliability, reducing manufacturing costs, and allowing for flexible adjustment of the number of yarn tube shafts driven by the installation platform as needed.

[0004] However, the existing technical solutions still have some shortcomings in actual implementation. The device only uses a single fan to recover roving ends. When multiple roving ends need to be processed, the negative pressure will be dispersed in the yarn suction pipe, resulting in incomplete adsorption of some roving ends. In particular, the tail yarns at the edge of the roving bobbin or with tight knots are prone to remain. At the same time, under the drive of a single fan, the opening structure needs to process multiple roving ends simultaneously. If the load is too high, the opening will be insufficient. Unopened yarn balls cannot be reused, which still causes fiber waste. Moreover, the proportion of short fibers and the number of knots in the opened fibers are relatively high, which affects the quality of subsequent reuse. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that the existing technology only uses a single fan to recover roving ends, when multiple roving ends need to be processed, the negative pressure will be dispersed in the yarn suction pipe, resulting in incomplete adsorption of some roving ends, especially the edges of the roving bobbin or the tail yarn with tight knots, which are prone to remain. At the same time, under the drive of a single fan, the opening structure needs to process multiple roving ends simultaneously. If the load is too high, the problem of insufficient opening will easily occur. Unopened yarn balls cannot be reused, which still causes fiber waste. Moreover, the proportion of short fibers and the number of knots in the opened fibers are relatively high, which affects the quality of subsequent reuse.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A yarn tail removal device includes a removal component; an adjustment component for adjusting the adsorption height and angle; and a filter component for separating the yarn ends. The cleaning assembly includes: a body; a first fan fixed to the left side of the body interior by external bolts; and a second fan fixed to the right side of the body interior by external bolts.

[0012] As a further embodiment of this utility model: the adjustment assembly further includes a belt and a small motor; the belt is disposed on the lower end surface of the rotating drum, the inner surface of the belt is engraved with transmission teeth, and the lower end surface of the rotating drum is provided with transmission teeth that mesh with the inner surface of the belt; the power output end of the small motor is keyed to the lower end of the rotating drum.

[0013] As a further embodiment of this utility model, the adjusting component further includes a cylinder; the cylinder is installed at the lower end of the lifting plate, and the power output end of the cylinder is fixed at the lower end of the lifting plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a dual-fan design for the cleaning component, combined with a diversion structure consisting of a first air duct, a second air duct, a first yarn suction pipe, a second yarn suction pipe, a first yarn suction branch pipe, and a second yarn suction branch pipe, to disperse the negative pressure into two independent transmission paths, avoiding the problem of negative pressure dispersion by a single fan. At the same time, the combination of a slanted tee and connecting pipe enables the roving head at the output end of the dual fans to converge, ensuring the negative pressure strength and adsorption efficiency, and improving the fullness of roving head opening.

[0016] 2. This utility model uses the cylinder of the adjusting component to drive the lifting plate to slide along the machine body, thereby realizing the height adjustment of the first and second yarn suction branches. In conjunction with a small motor to drive the rotating drum to rotate, multiple sets of rotating drums are driven to rotate synchronously through belt transmission, so that the roving bobbin placed on the rotating drum rotates accordingly, making it easier to loosen and expose the tail end of the roving. At the same time, the yarn suction angle can be adjusted to solve the problem of dead corners in yarn suction and improve the overall suction.

The grid-type filter is detachable for easy cleaning and maintenance, and the uniform small holes on the surface of the lint bag ensure the effective collection of short fibers without obstructing airflow, thus guaranteeing the purity of the recycled fibers.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0023] Example 1: Please see Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a yarn tail machine cleaning device, including a cleaning component 1; an adjustment component 2 for adjusting the adsorption height and angle; and a filter component 3 for separating the yarn ends. The cleaning component 1 includes: a body 101; a first fan 102 fixed to the left side of the body 101 by external bolts; and a second fan 103 fixed to the right side of the body 101 by external bolts. Adjustment component 2 includes: a lifting plate 202 slidably connected to the rear of the body 101; and a rotating drum 201 connected to the upper end of the lifting plate 202 via a bearing; The filter assembly 3 includes: a filter box 301 disposed on the left side of the body 101; and a grid-type filter screen 302 that can be detachably installed inside the filter box 301.

[0024] Specifically, the cleaning component 1 also includes: a first duct 104 and a second duct 105; the first duct 104 is connected to the input end of the first fan 102; and the second duct 105 is connected to the input end of the second fan 103.

[0025] Furthermore, the negative pressure generated by the operation of the first fan 102 is transmitted to the first yarn suction pipe 106 through the first air duct 104 connected to the input end, and the negative pressure generated by the operation of the second fan 103 is transmitted to the second yarn suction pipe 107 through the second air duct 105 connected to the input end.

[0026] Specifically, the cleaning component 1 also includes: a first suction tube 106 and a second suction tube 107; the first suction tube 106 is connected to the end of the first air duct 104; and the second suction tube 107 is connected to the end of the second air duct 105.

[0027] Furthermore, the negative pressure is transmitted through the first yarn suction tube 106 to the lower first yarn suction branch tube 108, and through the second yarn suction tube 107 to the lower second yarn suction branch tube 109.

[0028] Specifically, the cleaning component 1 also includes: a first yarn suction branch pipe 108 and a second yarn suction branch pipe 109; the first yarn suction branch pipe 108 is connected to the lower end of the first yarn suction pipe 106; and the second yarn suction branch pipe 109 is connected to the lower end of the second yarn suction pipe 107.

[0029] Furthermore, the first suction branch pipe 108 uses negative pressure to draw in the roving head of the corresponding area, while the second suction branch pipe 109 simultaneously draws in the roving head of another area.

[0030] In use, the first fan 102 and the second fan 103 in the cleaning component 1 are started and run synchronously. The negative pressure generated by the operation of the first fan 102 is transmitted to the first yarn suction pipe 106 through the first air duct 104 connected to the input end, and then transmitted to the first yarn suction branch pipe 108 at the lower end through the first yarn suction pipe 106. The first yarn suction branch pipe 108 uses the negative pressure to suck in the roving head in the corresponding area. At the same time, the negative pressure generated by the operation of the second fan 103 is transmitted to the second yarn suction pipe 107 through the second air duct 105 connected to the input end, and then transmitted to the second yarn suction pipe 107 through the second yarn suction pipe 107. The yarn is transferred to the second suction branch pipe 109 at the lower end. The second suction branch pipe 109 simultaneously sucks in the roving heads from another area. The sucked-in roving heads enter the first fan 102 and the second fan 103 respectively. After being dispersed by the opening structure inside the fan, the roving heads in the second fan 103 are transported to one branch of the oblique tee 110 through the connecting pipe 111 connected to its output end and enter the oblique tee 110. The roving heads in the first fan 102 directly enter the other branch of the oblique tee 110 through its output end. The two types of roving heads converge in the oblique tee 110.

[0031] In summary, this utility model, through the dual-fan design of the cleaning component 1, combined with the diversion structure of the first air duct 104, the second air duct 105, the first yarn suction pipe 106, the second yarn suction pipe 107, the first yarn suction branch pipe 108, and the second yarn suction branch pipe 109, disperses the negative pressure into two independent transmission paths, avoiding the problem of negative pressure dispersion by a single fan. At the same time, the oblique tee 110 and the connecting pipe 111 are combined to realize the convergence of the roving heads at the output ends of the dual fans, ensuring the negative pressure strength and adsorption efficiency, and improving the fullness of the roving head opening.

[0032] Example 2: Please see Figures 1-5 This is the second embodiment of the present utility model.

[0033] Specifically, the clearing component 1 also includes: a slanted tee 110 and a connecting pipe 111; the slanted tee 110 is connected to the output end of the first fan 102; the connecting pipe 111 is connected to the branch port of the slanted tee 110.

[0034] Furthermore, the roving head in the second fan 103 is transported to one branch of the oblique tee 110 through the connecting pipe 111 connected to its output end and enters the oblique tee 110. The roving head in the first fan 102 directly enters the other branch of the oblique tee 110 through its output end. The two types of roving heads converge in the oblique tee 110.

[0035] Specifically, the adjustment component 2 also includes: a belt 203 and a small motor 204; the belt 203 is disposed on the lower end surface of the rotating drum 201, the inner surface of the belt 203 is engraved with transmission teeth, and the lower end surface of the rotating drum 201 is provided with transmission teeth that mesh with the inner surface of the belt 203; the power output end of the small motor 204 is keyed to the lower end of the rotating drum 201.

[0036] Furthermore, since the transmission teeth on the lower surface of the rotating drum 201 mesh with the transmission teeth on the inner surface of the belt 203, the rotating drum 201 will drive the belt 203 to rotate synchronously when it rotates, and thus drive several rotating drums 201 to rotate through the transmission action of the belt 203.

[0037] Specifically, the adjustment component 2 also includes: a cylinder 205; the cylinder 205 is installed at the lower end of the lifting plate 202, and the power output end of the cylinder 205 is fixed at the lower end of the lifting plate 202.

[0038] Furthermore, the start cylinder 205 is activated, and its power output end pushes the lifting plate 202 to slide up and down along the inner wall of the machine body 101.

[0039] Specifically, the filter assembly 3 also includes: a velvet bag 303; the velvet bag 303 is installed on one side of the filter box 301, and the surface of the velvet bag 303 is provided with uniform small holes.

[0040] Furthermore, the light, short lint is collected through a lint bag 303 installed on one side of the filter box 301.

[0041] In use, the cylinder 205 in the adjustment assembly 2 is activated, and its power output end pushes the lifting plate 202 to slide up and down along the inner wall of the machine body 101 to adjust the height of the yarn suction structure. At the same time, the small motor 204 is activated, and its power output end directly drives the rotating drum 201 to rotate. Since the transmission teeth on the lower surface of the rotating drum 201 mesh with the transmission teeth on the inner surface of the belt 203, the rotation of the rotating drum 201 will drive the belt 203 to rotate synchronously. In turn, through the transmission action of the belt 203, several rotating drums 201 are driven to rotate. The roving bobbins placed on the rotating drum 201 rotate synchronously with the rotating drum 201, making it easier to loosen the tail end of the roving. The yarn ends are dispersed and exposed, making it easier for them to be sucked in by the yarn suction structure. After the two types of roving ends converge in the oblique tee 110, they flow together to the filter assembly 3 on the left side of the machine body 101. The mixed airflow carrying roving ends, short fibers and impurities enters the filter box 301 of the filter assembly 3. It first passes through the grid-type filter screen 302 that can be detachably installed inside the filter box 301 to intercept large impurities such as small knots and seed dust that have not been loosened. The filtered airflow continues to flow in the filter box 301. The light and short fibers are collected through the fiber bag 303 installed on one side of the filter box 301, while the usable fibers are retained in the filter box 301, completing the removal of the tail yarn and the separation and recycling of resources.

[0042] In summary, this invention uses the cylinder 205 of the adjusting component 2 to drive the lifting plate 202 to slide along the machine body 101, thereby adjusting the height of the first yarn suction branch pipe 108 and the second yarn suction branch pipe 109. This, combined with the small motor 204 driving the rotating drum 201 to rotate, and the belt 203 driving multiple sets of rotating drums 201 to rotate synchronously, causes the roving bobbins placed on the rotating drums 201 to rotate accordingly, making it easier to loosen and expose the yarn tail. Simultaneously, the yarn suction angle can be adjusted to solve the problem of dead corners in yarn suction and improve the overall suction effectiveness. This invention uses the grid-type filter 302 of the filter component 3 to intercept large-sized impurities, and the lint bag 303 on one side of the filter box 301 to collect light, short fibers, achieving graded separation. The detachable design of the grid-type filter 302 facilitates cleaning and maintenance, and the uniform small holes on the surface of the lint bag 303 ensure effective short fiber collection without obstructing airflow, guaranteeing the purity of the recycled fibers.
