Description

Technical Field

[0001] The invention relates to the technical field of random inspection of textile auxiliaries, and in particular to a high-efficiency FDY textile auxiliaries synchronous layered random inspection sampling device. Background Art

[0002] FDY (Fully Drawn Yarn) refers to winding yarn with high orientation and medium crystallinity produced after the introduction of stretching in the spinning process. It belongs to chemical fiber filament. Introducing FDY in the spinning process can obtain winding yarn with high orientation and medium crystallinity. Conventional fully drawn yarns of polyester and nylon are all chemical fiber filaments. FDY fabrics feel smooth and soft, and are often used to weave imitation silk fabrics. They are widely used in clothing and home textiles.

[0003] FDY textile auxiliaries are needed in the textile process. During the production process of textile auxiliaries, they will be sampled. The sampling device is generally used for sampling. The textile auxiliaries are sampled at different depths by using the sampling device. The composition of the textile auxiliaries samples taken at different depths may be different.

[0004] Chinese patent publication number CN117232910B discloses a sampling device for FDY textile auxiliaries sampling, including a main shaft, a sampling tube, an adjustment component and a control component. In the sampling process, the sampling device inserts the main shaft into a container containing textile auxiliaries, and the sampling tube installed on the main shaft synchronously enters the container containing textile auxiliaries. When the lower end of the main shaft contacts the bottom of the container, the adjustment component evenly distributes multiple sampling tubes on the main shaft in the container to ensure that the sampling tube can sample textile auxiliaries at different positions in the container. The control component controls the piston disc to slide in the sampling tube, and the piston disc slides in the sampling tube to suck the textile auxiliaries into the sampling cavity through the water inlet. The water inlet is only located on one side of the sampling tube, and the textile auxiliaries at the same height cannot be evenly collected, and it is not convenient to take out the textile auxiliaries in one of the sampling tubes for testing after sampling. Summary of the invention

[0005] In view of the above problems, a high-efficiency FDY textile auxiliaries synchronous stratified random inspection sampling device is provided. By setting an annular suction channel that can be opened when the piston disk moves at the bottom of the sampler, the piston disk can draw the textile auxiliaries at the same height into the sampling cavity through the annular suction channel when the piston disk moves in the sampler, thereby solving the problem that the existing sampling device cannot evenly collect textile auxiliaries at the same height.

[0006] In order to solve the problems of the prior art, the present invention provides a high-efficiency FDY textile auxiliary agent synchronous layered random inspection sampling device, comprising samplers arranged and connected at equal intervals in the longitudinal direction, and a driving shaft slidingly passing through all the samplers, the inner cavity of the sampler is provided with a piston disk connected to the driving shaft, the piston disk divides the inner cavity of the sampler into a sampling cavity and a pressure cavity, the bottom end of the sampler is provided with an annular suction channel that can connect the sampling cavity and the textile auxiliary agent when the piston disk moves, the sampler is also provided with a one-way discharge channel that can connect the textile auxiliary agent and the sampling cavity, and a driving member for guiding the piston disk to move relative to the driving shaft.

When the piston disc moves upward, the annular suction channel opens, so that the textile auxiliaries around the sampler can be smoothly sucked into the sampling cavity through the channel. Due to the design of the annular suction channel, it is ensured that no matter where the piston disc moves to, the textile auxiliaries at the same height can be evenly sucked into the sampling cavity, thereby solving the problem of uneven sampling that may exist in traditional sampling devices when collecting textile auxiliaries.

[0018] In addition, the drive can accurately control the movement of the piston disc in a single sampler, ensuring that the piston disc can move according to the preset path and speed when sampling.

DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, this application provides:

[0032] The invention discloses a high-efficiency FDY textile auxiliary synchronous layered sampling device, comprising samplers 1 connected and arranged at equal intervals in the longitudinal direction, and a driving shaft 2 slidingly passing through all the samplers 1, the inner cavity of the sampler 1 is provided with a piston disc 15 connected with the driving shaft 2, the piston disc 15 divides the inner cavity of the sampler 1 into a sampling cavity 11 and a pressure cavity 12, the bottom end of the sampler 1 is provided with an annular suction channel 13 which can connect the sampling cavity 11 and the textile auxiliary when the piston disc 15 moves, the sampler 1 is also provided with a one-way discharge channel 14 which can connect the textile auxiliary and the sampling cavity 11, and a driving member for guiding the piston disc 15 to move relative to the driving shaft 2.

[0033] The samplers 1 are connected and arranged at equal intervals in the longitudinal direction to form a continuous sampling array. A piston disc 15 is provided inside each sampler 1 to meet the needs of synchronous stratified random sampling. Specifically, the inner cavity of the sampler 1 is divided into a sampling chamber 11 and a pressure chamber 12 by the piston disc 15. The piston disc 15 is connected to the drive shaft 2 that runs through all the samplers 1. Through the linear motion of the drive shaft 2, the piston discs 15 in all the samplers 1 can be driven to move synchronously.

[0034] An annular suction channel 13 is provided at the bottom end of the sampler 1. When the piston disc 15 moves in the sampler 1, the annular suction channel 13 can be opened or closed as needed to connect the sampling chamber 11 and the textile auxiliaries. This design enables the annular suction channel 13 to open when the piston disc 15 moves upward, and the textile auxiliaries can be smoothly sucked into the sampling chamber 11 through the channel. When the piston disc 15 moves upward, the annular suction channel 13 is closed to ensure that the textile auxiliaries in the sampling chamber 11 will not leak.

[0035] In addition to the annular suction channel 13, the sampler 1 is also provided with a one-way discharge channel 14. This channel can ensure that during the sampling process, the textile auxiliary agent can only flow from the textile auxiliary agent source to the sampling chamber 11, and will not flow in the opposite direction. The design of the one-way discharge channel 14 further improves the accuracy and reliability of sampling.

[0036] In order to achieve precise control of the piston disc 15, a driving member is provided in the device. The driving member guides the piston disc 15 to move relative to the driving shaft 2 by controlling the rotation or linear motion of the driving shaft 2. This design allows the user to adjust the moving speed and position of the piston disc 15 as required, thereby achieving precise sampling of textile auxiliaries.

[0037] In general, this efficient FDY textile auxiliaries synchronous layered sampling device realizes efficient, synchronous and layered sampling of textile auxiliaries through its unique sampler 1 structure and drive system. The device not only improves the accuracy and reliability of sampling, but also greatly simplifies the sampling process and improves work efficiency.

[0038] In this embodiment, an annular suction channel 13 that can be opened when the piston disk 15 moves is provided at the bottom of the sampler 1, so that when the piston disk 15 moves in the sampler 1, the textile auxiliaries at the same height can be sucked into the sampling chamber 11 through the annular suction channel 13, thereby solving the problem that the existing sampling device cannot evenly collect textile auxiliaries at the same height. At the same time, the piston disk 15 in a single sampler 1 can be guided to move through the driving member, so as to take out the control auxiliaries in the single sampler 1 for testing.

[0039] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the bottom end of the sampler 1 is open and is provided with a movable disk 16, the drive shaft 2 slides through the movable disk 16, the inner diameter of the bottom end of the sampler 1 gradually decreases from top to bottom, the outer diameter of the movable disk 16 gradually decreases from top to bottom, the outer circumferential surface of the movable disk 16 abuts against the bottom circumferential surface of the sampler 1, and when the movable disk 16 moves upward, an annular suction channel 13 is formed between the outer circumferential surface of the movable disk 16 and the bottom circumferential surface of the sampler 1.

[0040] The bottom end of the sampler 1 is open and is provided with a movable disk 16. The movable disk 16 can move during the sampling process. The drive shaft 2 slides through the movable disk 16, which enables the movable disk 16 to move up and down along the drive shaft 2, thereby controlling the working state of the sampler 1.

[0041] The inner diameter of the bottom end of the sampler 1 is designed to be gradually reduced from top to bottom. This design enables the sampler 1 to better adapt to the flow of textile auxiliaries at different heights when collecting textile auxiliaries, ensuring the uniformity of sampling.

[0042] Similarly, the outer diameter of the movable disk 16 also decreases gradually from top to bottom. This design enables the outer circumference of the movable disk 16 to form an annular suction channel 13 with the bottom circumference of the sampler 1 when the movable disk 16 moves upward. This channel can effectively draw the textile auxiliary agent from the auxiliary agent source into the sampling cavity 11 of the sampler 1 during the sampling process.

[0043] When the movable disk 16 moves upward, due to the special design of the movable disk 16 and the circumferential surface of the bottom end of the sampler 1, the gap between the two gradually increases, forming an annular suction channel 13. This channel will continuously change size with the movement of the movable disk 16, thereby achieving uniform collection of textile auxiliaries at different heights.

[0044] In addition, the tight contact between the outer circumferential surface of the movable disk 16 and the bottom circumferential surface of the sampler 1 ensures the sealing and stability of the annular suction channel 13. This can not only prevent the leakage of textile auxiliaries during sampling, but also improve the accuracy and reliability of sampling.

[0045] In general, this efficient FDY textile auxiliary synchronous layered sampling device realizes efficient, synchronous and layered sampling of textile auxiliary agents through its unique sampler 1 design and movable disk 16 structure. This device has a wide range of application prospects in the textile production process and can greatly improve production efficiency and product quality.

[0046] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, a limit platform 17 extending radially is provided at the bottom opening of the sampler 1, and a limit bolt 171 extending upward is provided on the limit platform 17. The limit bolt 171 slides through the movable disk 16, and a bolt cap 172 is provided at the top of the limit bolt 171.

[0047] The bottom end of the sampler 1 is open, and a limit platform 17 is extended from the opening along the radial direction of the sampler 1. The limit platform 17 can not only ensure the stable movement of the movable disk 16 in the sampler 1, but also prevent the movable disk 16 from deflecting or rotating during the sampling process.

[0048] On the limiting platform 17, there is a limiting bolt 171 extending upward. The limiting bolt 171 slides through the movable disk 16, and a bolt cap 172 is provided at the top thereof. The limiting bolt 171 and the movable disk 16 are closely matched, and the upward and downward movement of the movable disk 16 in the sampler 1 is realized by the limiting bolt 171.

[0049] When the movable disk 16 moves upward, it slides along the stopper bolt 171, and forms an annular suction channel 13 with the bottom circumference of the sampler 1. The size of this channel changes with the movement of the movable disk 16, thereby achieving uniform collection of textile auxiliaries at different heights.

[0050] The design of the bolt cap 172 not only facilitates the operation of the stop bolt 171, but also can prevent the movable disk 16 from accidentally falling off or being damaged during the sampling process to a certain extent. By rotating the bolt cap 172, the position of the stop bolt 171 in the sampler 1 can be easily adjusted to meet different sampling requirements.

[0051] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the driving member includes a connecting sleeve 3 that slides through the top of the sampler 1 , the connecting sleeve 3 is threadedly connected to the driving shaft 2 , and the bottom end of the connecting sleeve 3 penetrates the pressure chamber 12 and is connected to the piston disc 15 .

[0052] A threaded connection is adopted between the connecting sleeve 3 and the driving shaft 2. This connection mode not only ensures the stability of the connection, but also allows the connecting sleeve 3 to slide accurately on the driving shaft 2. By rotating the connecting sleeve 3 relative to the driving shaft 2, the moving distance of the connecting sleeve 3 in the axial direction can be accurately controlled, thereby realizing accurate control of the internal components of the sampler 1.

[0053] The bottom end of the connecting sleeve 3 not only penetrates the pressure chamber 12 of the sampler 1, but is also tightly connected to the piston disc 15 inside the pressure chamber 12. This connection ensures that the piston disc 15 can move synchronously when the connecting sleeve 3 slides on the driving shaft 2. The piston disc 15 is a key component in the pressure chamber 12 of the sampler 1. Its movement will change the pressure in the pressure chamber 12, thereby affecting the sampling process of the sampler 1.

[0054] When sampling is required, the connecting sleeve 3 is rotated relative to the drive shaft 2 to slide on the drive shaft 2, driving the piston disc 15 to move in the pressure chamber 12. The movement of the piston disc 15 changes the pressure in the pressure chamber 12, so that the sampler 1 can absorb or discharge the sample. In this way, the driving member achieves precise control of the sampling process of the sampler 1 through the synergistic effect of the connecting sleeve 3 and the piston disc 15.

[0055] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a pressure relief hole 18 is provided at the top of the sampler 1.

[0056] During the sampling process, the pressure in the pressure chamber 12 may change as the piston disc 15 moves. The pressure relief hole 18 allows the gas in the pressure chamber 12 to escape, thereby preventing the sampler 1 from being damaged or dangerous due to excessive pressure.

[0057] In addition, the pressure relief hole 18 also plays a role in balancing the pressure. After the sampling is completed, the piston disc 15 is restored to the initial position by operating the driving member. At this time, the pressure relief hole 18 can continue to remain open, so that the pressure chamber 12 and the external environment reach a pressure balance. This can not only protect the sampler 1 from the influence of the internal residual pressure, but also ensure the smooth progress of the next sampling operation.

[0058] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the bottom end of the connecting sleeve 3 is rotatably connected to the piston disc 15 .

[0059] When the connecting sleeve 3 rotates relative to the driving shaft 2, in order to prevent the connecting sleeve 3 from transmitting torque to the piston disc 15 and increasing its rotational resistance, the connecting sleeve 3 is rotationally connected to the piston disc 15 so that the connecting sleeve 3 can stably drive the piston disc 15 to move with less resistance.

[0060] like Figure 4 As shown, the piston disk 15 has a straight disk section that intermittently cooperates with the inner wall of the sampler 1, and a conical disk section that intermittently cooperates with the lower port of the sampler 1.

[0061] The straight disk section of the piston disk 15 can fit with the sampler 1 in a clearance, and the straight disk section is provided with a sealing ring, which can effectively prevent the textile auxiliaries in the sampling chamber 11 from flowing into the pressure chamber 12. The conical disk can be engaged with the inner port of the sampler 1 when moving downward, so as to completely press out the textile auxiliaries in the sampling chamber 11, thereby preventing the textile auxiliaries from remaining in the sampling chamber 11.

[0062] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the one-way discharge channel 14 is located on the inner conical surface of the sampler 1 with a gradually decreasing inner diameter.

[0063] A one-way valve is provided in the one-way discharge channel 14, and the one-way discharge channel 14 is located at the lowest point of the sampling chamber 11. When the piston disc 15 moves downward and abuts against the bottom end of the sampling chamber 11, the textile auxiliaries in the sampling chamber 11 can completely overflow outward through the one-way discharge channel 14, thereby facilitating detection.

[0064] like Figure 2 As shown, a spacing adjustment mechanism is provided between adjacent samplers 1, and the spacing adjustment mechanism includes an external threaded rod 41 and an internal threaded barrel 42 respectively connected to the two samplers 1, the external threaded rod 41 and the internal threaded barrel 42 are threadedly connected, and the external threaded rod 41 and the internal threaded barrel 42 are distributed circumferentially on the outside of the driving shaft 2.

[0065] The spacing adjustment mechanism consists of two parts, an external threaded rod 41 and an internal threaded barrel 42, which are respectively connected to two adjacent samplers 1. One end of the external threaded rod 41 is fixedly connected to one sampler 1, while the other end has an external thread that can be threadedly connected to the internal threaded barrel 42. Similarly, one end of the internal threaded barrel 42 is fixedly connected to another sampler 1, while the inside has an internal thread that matches the external threaded rod 41.

[0066] The threaded connection design between the external threaded rod 41 and the internal threaded barrel 42 allows the user to adjust the relative position between the two by rotating the external threaded rod 41 or the internal threaded barrel 42, thereby changing the spacing between adjacent samplers 1. This adjustment method is simple and intuitive, and has high accuracy and stability.

[0067] It is worth mentioning that the external threaded rod 41 and the internal threaded barrel 42 are distributed circumferentially on the outside of the drive shaft 2. Such a layout design not only makes full use of the space, making the sampler 1 system more compact, but also facilitates the user to perform the spacing adjustment operation. At the same time, since the external threaded rod 41 and the internal threaded barrel 42 are located on the outside of the drive shaft 2, the threaded connection between them will not be affected by the movement of the drive shaft 2, thereby ensuring the stability and reliability of the spacing adjustment.

[0068] In actual operation, the user can adjust the spacing between adjacent samplers 1 by rotating the external threaded rod 41 or the internal threaded barrel 42 according to specific needs. When the spacing needs to be increased, the external threaded rod 41 can be rotated clockwise or the internal threaded barrel 42 can be rotated counterclockwise to make the two relatively far apart; when the spacing needs to be reduced, the external threaded rod 41 can be rotated counterclockwise or the internal threaded barrel 42 can be rotated clockwise to make the two relatively close. Through continuous adjustment and experimentation, users can find the spacing setting that best suits their sampling needs.

[0069] like Figure 2 As shown, the sampling device also includes a bracket arranged on the top of the sampler 1 at the highest point, and a driving rod 51 threadedly connected to the bracket is arranged on the bracket, the bottom end of the driving rod 51 is rotatably connected to the top end of the driving shaft 2, and the driving shaft 2 is slidably connected to the bracket.

[0070] The bracket includes an upper fixing seat 52 and a lower fixing seat 53. The driving rod 51 passes through the upper fixing seat 52 and is threadedly connected thereto. The lower fixing seat 53 is provided with an engaging opening. The driving shaft 2 passes through the engaging opening and slides with it. The bottom end of the driving rod 51 rotates with the top end of the driving shaft 2.

[0071] A driving disc 511 coaxial with the driving rod 51 is disposed at the top end thereof, and a driving handle 512 deviating from the axis thereof is disposed at the top end of the driving disc 511 .

[0072] The sampling device not only includes multiple samplers 1 and a mechanism for adjusting the spacing between the samplers 1, but also has a sturdy and stable bracket on the top of the highest sampler 1. As the core supporting structure of the entire sampling device, this bracket must not only be able to bear the weight of the sampler 1 and its accessories, but also maintain a stable posture during the sampling process to ensure the accuracy of sampling.

[0073] The bracket is composed of an upper fixing seat 52 and a lower fixing seat 53, forming a stable whole. The upper fixing seat 52 is the main load-bearing part of the bracket, which is responsible for supporting and fixing the driving rod 51. The driving rod 51 passes through the upper fixing seat 52 and is tightly connected with it through a threaded connection. This connection method not only ensures the firmness of the connection, but also allows the user to adjust the height of the driving rod 51 by rotating it to meet different sampling requirements.

[0074] The lower fixing seat 53 is responsible for fixing and supporting the drive shaft 2. A fitting opening is provided on the lower fixing seat 53, and the drive shaft 2 passes through the fitting opening and forms a sliding fit with the fitting opening. This design allows the drive shaft 2 to slide up and down within a certain range while maintaining a vertical direction, so as to meet the sampling requirements of the sampler 1 at different heights.

[0075] In order to facilitate the user to operate the driving rod 51, a driving disk 511 coaxial with the driving rod 51 is provided at the top of the driving rod 51. The driving disk 511 not only increases the contact area with the user and improves the stability of the operation, but also enables the user to rotate the driving rod 51 by rotating the driving disk 511 through its circular shape, thereby achieving precise control of the sampler 1.

[0076] In addition, in order to further improve the convenience of operation, a driving handle 512 is provided at the top of the driving disk 511, which is offset from its axis. The design of the driving handle 512 allows the user to rotate the driving disk 511 by holding it and applying torque, without relying too much on the strength of the fingers. Such a design not only reduces the difficulty of operation, but also improves the comfort and efficiency of operation.

[0077] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
