Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of silk suction gun, concretely to multifunctional silk suction gun structure. BACKGROUND

[0002] In the industrial production field of textile, chemical fiber, etc., the silk suction gun as a key auxiliary tool is widely used in the scenes of spinning head, bobbin changing operation, waste silk recycling and production environment maintenance. Its core function is to realize the rapid handling and positioning of the filament bundle through the negative pressure adsorption principle. The core function of the traditional silk suction gun is to realize the attraction and conveying of the yarn through the friction between the airflow injection and the fiber. Its internal structure mainly focuses on the design of the airflow channel such as nozzle and Laval tube to optimize the silk suction efficiency and tension control. This kind of equipment usually does not set a filter screen because its working principle depends on the smooth flow of airflow. The filter screen may increase the airflow resistance and affect the performance.

[0003] However, in specific application scenarios, the function of the silk suction gun will be extended to waste silk recycling or air purification. For example, in the waste silk recycling process, in order to prevent the knotted fiber debris or impurities from entering the airflow system, some silk suction guns will set a filter screen at the air inlet or air outlet to intercept particulate matter and protect the internal structure of the equipment. In addition, if the silk suction gun is used in an environment with high requirements for air quality, such as a dust-free workshop, it may integrate a filter screen inside to filter the tiny particles in the air and ensure the cleanliness of the production environment. The setting of the filter screen in the silk suction gun needs to balance the filtering effect and airflow resistance. Although a small filter screen aperture can improve the filtering accuracy, it may significantly increase the airflow resistance and reduce the silk suction efficiency. A large aperture has limited filtering effect and cannot meet the needs of specific scenarios. Therefore, the design of the filter screen needs to be optimized according to the specific use and working environment of the silk suction gun.

[0004] At present, the silk suction guns with filter screen structure on the market have certain limitations in structure design and function implementation. For example, during the operation of the silk suction gun, the knotted waste silk and other impurities are easily and uniformly distributed on the surface of the filter screen. At this time, the suction force of the suction port of the silk suction tube will be significantly reduced. Therefore, the operator needs to stop the operation, disassemble the pipeline and clean it manually, which interrupts the operation process and reduces the continuous working capacity of the silk suction gun. In addition, the silk suction tube of the silk suction gun is usually made of hard metal pipe, such as stainless steel pipe. Although it has certain durability, it cannot be bent or adjusted in angle. The hard silk suction tube needs to be moved or the operator's position needs to be adjusted to realize the adsorption, which significantly increases the labor intensity and operation time and reduces the production efficiency.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] Please refer to Figures 1-4 The present application provides a technical scheme: a multifunctional silk suction gun structure, comprising: a body 1, a suction port of the body 1 is fixedly connected with a first metal pipe 2, an end portion of the first metal pipe 2 away from the body 1 is threadedly connected with a second metal pipe 3, an end portion of the second metal pipe 3 away from the body 1 is threadedly connected with a third metal pipe 4, an impurity filtering unit is arranged inside the first metal pipe 2, the impurity filtering unit is connected with the first metal pipe 2 and the second metal pipe 3 through a mounting unit, and the impurity filtering unit comprises: a filter plate 5, the filter plate 5 is located inside the first metal pipe 2, a plurality of filter holes 6 are uniformly formed on the surface of the filter plate 5, a round rod 7 is rotatably connected to the inner wall of the filter plate 5, an impeller 8 is fixedly connected to one end of the round rod 7, a pair of support rods 9 are fixedly connected to the outer wall of the round rod 7 away from the impeller 8, a plurality of brush hooks 10 are fixedly connected to the outer wall of the support rods 9 close to the filter plate 5, and the brush hooks 10 are in close contact with the filter plate 5.

[0023] In the implementation process, it is particularly worth pointing out that the body 1 is the main body of the suction gun, and the specific working principle is the same as that of the main body of the known suction gun on the market. The structure of the present application is not improved, so it will not be described in detail. The first metal pipe 2 not only plays a connecting role between the body 1 and the subsequent pipeline, but also is made of stainless steel material, which has good strength and corrosion resistance, and can adapt to different working environments. The size of the filter hole 6 on the filter plate 5 is carefully designed, which can not only effectively intercept the knotted fibers and impurities, but also will not cause too much resistance to the normal suction airflow. The rotating connection between the circular rod 7 and the inner wall of the filter plate 5 adopts a sealed bearing to ensure flexible and stable rotation and reduce energy loss. The impeller 8 is composed of multiple curved blades, and the shape of the blades (such as spiral or airfoil) can guide the flow direction of the fluid (such as air or water). When the fluid flows through the blades, the blades are subjected to the combined action of lift and drag. The pressure difference caused by the flow velocity difference between the upper and lower surfaces of the blade produces a force perpendicular to the flow direction (similar to the principle of an airplane wing). The force parallel to the flow direction generated by the direct impact of the fluid on the blade, and the resultant force of the blade produces a rotating torque, which drives the impeller to rotate around the shaft. The circular rod 7 can be driven to rotate under the action of the airflow. The material of the support rod 9 is strong and can withstand the reaction force generated when the brush hook 10 cleans the filter plate 5, ensuring the stability of the structure. The brush hook 10 is made of nylon material, which can effectively clean the impurities on the surface of the filter plate 5 without damaging the filter plate 5.

[0024] Further, the center points of the impeller 8 and the circular rod 7 are located on the same horizontal line, and a pair of support rods 9 are symmetrically arranged relative to the center point of the circular rod 7.

[0025] In the implementation process, it is particularly worth pointing out that the center points of the impeller 8 and the circular rod 7 are located on the same horizontal line, which ensures that the impeller 8 can uniformly transmit power to the circular rod 7 when subjected to airflow, making the rotation of the circular rod 7 more stable and reducing vibration and noise caused by uneven power. A pair of support rods 9 are symmetrically arranged relative to the center point of the circular rod 7, so that the two support rods 9 can balance the cleaning of the filter plate 5 during the rotation of the circular rod 7, avoiding uneven stress on the filter plate 5 due to excessive stress on one side, which affects the filtering effect and the service life of the filter plate 5. At the same time, this symmetrical structure also improves the stability and reliability of the entire filter unit, ensuring that it can work stably and continuously for a long time.

[0026] Further, the mounting unit comprises: a tetrafluoro ring 11 abutting against one side surface of the filter plate 5, the tetrafluoro ring 11 abutting against a base ring 12 away from the surface of the filter plate 5, the outer wall of the base ring 12 being fixedly connected with the inner wall of the first metal pipe 2, the end surface of the filter plate 5 away from the tetrafluoro ring 11 abutting against a pair of anti-skid blocks 14, the anti-skid blocks 14 being fixedly connected with abutting rods 13 away from the surface of the filter plate 5, the end portion of the abutting rod 13 away from the anti-skid block 14 being fixedly connected with a circular ring 15, the outer wall of the circular ring 15 being rotatably connected with a T-shaped ring 16, the outer wall of the T-shaped ring 16 being fixedly connected with the second metal pipe 3.

[0027] In the specific implementation process, it is particularly worth pointing out that the tetrafluoro ring 11 can provide good sealing between the filter plate 5 and the base ring 12, preventing impurities from leaking into the body 1 from between the filter plate 5 and the base ring 12, the base ring 12 is fixedly connected with the inner wall of the first metal pipe 2, and the connection mode adopts high-strength welding to ensure the firmness and sealing of the connection, the anti-skid blocks 14 are made of rubber material and have a large friction force, which can prevent the filter plate 5 from being displaced under the impact of airflow when abutting against the filter plate 5, the material of the abutting rod 13 has sufficient strength and rigidity, which can stably transmit the pressure of the anti-skid block 14 to the filter plate 5, the circular ring 15 is rotatably connected with the T-shaped ring 16 through a sealing bearing, and the rotatable connection design of the circular ring 15 and the T-shaped ring 16 enables flexible rotation when the second metal pipe 3 is connected or detached from the first metal pipe 2, reduces the resistance in the connection process, and ensures the tightness of the connection.

[0028] Further, the third metal pipe 4 is of a double-section structure, and a connecting unit is arranged between the double-section third metal pipes 4, the connecting unit comprising: a universal pipe 17 sleeved between the double-section third metal pipes 4, the outer wall of the universal pipe 17 being sleeved with pipe clamps 18 at both ends, and the pipe clamps 18 abutting against the outer wall of the universal pipe 17.

[0029] In the specific implementation process, it is particularly worth pointing out that the third metal pipe 4 adopts a double-section structure, which enables the length of the suction gun to be adjusted according to actual needs, increasing the flexibility of use, the universal pipe 17 as a key component for connecting the double-section third metal pipes 4 can withstand certain bending and torsional forces, ensuring that the airflow can flow smoothly when the angle of the third metal pipe 4 is adjusted, without leakage or airflow obstruction, and by adjusting the tightness of the pipe clamps 18, the connection between the universal pipe 17 and the double-section third metal pipes 4 can be ensured to be firm and reliable, preventing loosening or falling off during use.

[0030] Furthermore, the universal tube 17 is composed of a first soft layer 171, a metal memory layer 172, and a second soft layer 173. The two ends of the inner wall of the first soft layer 171 are respectively abutted against the outer wall of the double-section third metal tube 4. The outer wall of the first soft layer 171 is fixedly sleeved with the metal memory layer 172, and the outer wall of the metal memory layer 172 is fixedly sleeved with the second soft layer 173. The two ends of the outer wall of the second soft layer 173 are abutted against the inner wall of the pipe clamp 18.

[0031] In the specific implementation process, it is worth noting that the first soft layer 171 is made of rubber, which is soft and has a certain degree of elasticity. It can fit tightly against the outer wall of the double-section third metal tube 4 and play a sealing role to prevent air leakage when the universal tube 17 passes through it. The metal memory layer 172 is the core component of the universal tube 17. It has unique metal memory properties. When the universal tube 17 is bent and adjusted, it can return to its original shape under certain conditions. This allows the operator to easily adjust the angle of the third metal tube 4 and maintain a stable shape after adjustment without frequent adjustments. The second soft layer 173 plays a role in protecting the metal memory layer 172, preventing the metal memory layer 172 from being corroded and damaged by the external environment. At the same time, it can also increase the overall strength and durability of the universal tube 17. The second soft layer 173 is made of the same material as the first soft layer 171.

[0032] Working principle:

[0033] Basic process of yarn suction operation:

[0034] When the user performs the filament suction operation, first connect the machine body 1 to the external suction device, then start the external suction device and open the valve installed on the machine body 1. At this time, under the negative pressure generated by the suction device, the end of the third metal tube 4 away from the machine body 1 forms a suction force. The operator can bring the end close to the position where the filament needs to be suctioned to start the filament suction operation and suck in the filament.

[0035] Working principle of the impurity filtration unit: Impurity filtration

[0036] In the process of sucking silk operation, the medium (such as the mixture of air and silk) flowing through the filter plate 5 in the first metal pipe 2, the surface of the filter plate 5 is covered with filter holes 6, which can effectively intercept the tangled fibers and impurities in the medium, prevent these substances from entering the internal airflow system of the machine body 1, thereby protecting the internal structure of the machine body 1, avoiding equipment failure caused by impurity accumulation or winding, ensuring the stable operation of the suction gun, when the airflow flows through the impeller 8, it will drive the impeller 8 and the round rod 7 connected with it to rotate, the round rod 7 is installed with two support rods 9, the support rod 9 revolves around the round rod 7 as the center, the outer wall of the support rod 9 is fixedly connected with a plurality of brush hooks 10 close to the filter plate 5, in the process of revolution, the brush hook 10 will scratch the outside of the filter hole 6 on the surface of the filter plate 5 in a cycle, this scratching action can clean the tangled fibers or impurities blocked on the surface of the filter plate 5, so that the tangled fibers or impurities are not easy to cover the surface of the filter plate 5, thereby the suction force of the end of the third metal pipe 4 away from the machine body 1 is not easy to be obviously reduced, ensuring that the suction gun basically does not need to be disassembled for manual cleaning during single operation, without interrupting the operation process, significantly improving the continuous working ability of the suction gun.

[0037] The working principle of the connecting unit is:

[0038] The third metal pipe 4 adopts a double-section structure and is connected through a direction-adjustable universal pipe 17. This design enables the operator to flexibly adjust the orientation of the suction end of the third metal pipe 4 according to actual needs to meet the requirements of suctioning silk at different angles and positions. In addition, the universal pipe 17 is internally provided with a metal memory layer 172. The metal memory layer has metal memory performance and can maintain the adjusted shape after the universal pipe 17 is bent and adjusted, without the need for the operator to continuously adjust or move the device or change the position to achieve stable suction operation. This feature reduces the labor intensity of the operator, saves operation time, and is conducive to improving the overall production efficiency.

[0039] The working principle of the mounting unit and the disassembly and cleaning of the components are as follows:

[0040] After single suction silk operation is completed, the operator rotates the second metal pipe 3 counterclockwise to separate it from the first metal pipe 2. In the normal working state, the anti-slip block 14 exerts force against the filter plate 5 to fix and seal it. When the second metal pipe 3 is separated from the first metal pipe 2, the anti-slip block 14 no longer exerts force against the filter plate 5. At this time, the operator can easily take out the filter plate 5, the round rod 7, the impeller 8, the support rod 9, and the brush hook 10 from the inside of the second metal pipe 3 for thorough cleaning to remove possible residual impurities and tangled fibers, ensuring the cleanliness and performance of each component. After cleaning is completed, the operator resets each component and then locks the second metal pipe 3 with the first metal pipe 2 through threading. As the screw rotation continues to lock, the anti-slip block 14 close to the end of the filter plate 5 will exert pressure on the filter plate 5, making the filter plate 5 fully abut against the surface of the Teflon ring 11.

[0041] While the embodiments of the present application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the present application, which should be limited only by the appended claims and their equivalents.
