Description

Technical Field

[0001] This application relates to the field of textile equipment technology, and in particular to a warp stop strip fixing spacer. Background Technology

[0002] To ensure production efficiency and product qualification rate, looms must use warp stop frames to detect warp breakage. The warp stop frame consists of warp stop plates and warp stop strips to perform the function of detecting warp breakage. Typically, the warp stop strip has a rectangular cross-section and is fixed at both ends to the side walls of the warp stop frame. However, to cover the area traversed by the warp threads, the warp stop strip needs to be relatively long so that any broken warp thread can fall onto it. Consequently, under the influence of gravity, the middle of the warp stop strip sags. Therefore, a fixed partition needs to be installed in the middle of the warp stop strip to ensure its horizontality.

[0003] In the prior art, fixed partitions with grooves of fixed width are usually used to fit a stop warp strip of a fixed length. However, since different types of warp threads have different diameters, the stop warp strip needs to be adjusted in width to accurately detect whether the warp thread is broken. Therefore, it is necessary to produce fixed partitions with widths corresponding to the stop warp strip, which increases production and usage costs. Utility Model Content

[0004] This application provides a stop strip fixing spacer that achieves the effect of adjustable groove width.

[0005] The technical solution for a menstrual stop bar fixing spacer provided in this application is as follows:

[0006] A base, wherein a groove is provided in the middle of the base;

[0007] A first plate, the surface of the first plate abutting against the inner surface of the groove, and a first groove extending along the height direction of the first plate is formed on the surface;

[0008] The second plate has a surface abutting against the first plate and a second groove corresponding to the first groove on its surface. The second groove is parallel to the first groove. The other surface of the second plate abuts against the inner surface of the groove. The second plate is configured to slide relative to the first plate along the length direction of the groove, so that the first groove and the second groove form an adjustable-width groove through relative sliding.

[0009] By adopting the above technical solution, and by setting the first plate and the second plate, which can slide relative to each other and cooperate to form a groove, the single stop warp strip fixing spacer can accurately adapt to a variety of stop warp strips of different widths. The adjustable groove width allows the stop warp strip fixing spacer and the stop warp strip to achieve a tight fit without gaps. This eliminates the relative wobbling space between the stop warp strip and the stop warp strip fixing spacer under the high-frequency vibration of the loom, effectively preventing the connection from loosening and the impact wear between the contact surfaces caused by long-term vibration. This ensures the long-term stability of the stop warp strip position and extends the service life of the stop warp strip fixing spacer itself.

[0010] Optionally, the inner sidewall of the base is provided with protruding ridges at intervals along the height direction of the groove, and the surfaces of the first plate and the second plate near the inner sidewall of the base are respectively provided with corresponding sliding grooves that cooperate with the protruding ridges. The surfaces of the first plate and the second plate that abut against each other are respectively provided with complementary slots along the length direction of the groove.

[0011] By adopting the above technical solution, the protruding ridge of the base cooperates with the sliding grooves of the first plate and the second plate to provide motion guidance and stable support for the first plate and the second plate in the vertical direction, effectively preventing the first plate and the second plate from swaying up and down or tilting during the sliding process; the complementary slots between the first plate and the second plate restrict their separation and torsion within the plane where their surfaces abut; through the synergistic effect of the aforementioned two sets of structures, the relative movement of the first plate and the second plate is strictly limited to a single linear degree of freedom along the length of the groove, ensuring the smoothness and stability of the groove width adjustment, while making the first plate, the second plate and the base form a tightly integrated whole, improving the structural stability and vibration resistance of the stop strip fixing spacer.

[0012] Optionally, a scale extending along the length of the second plate is provided on the surface of the second plate away from the first plate, and the reading of the scale is used to display the width of the groove.

[0013] By adopting the above technical solution, the scale allows operators to intuitively read the current width of the groove, enabling quantitative and rapid adjustment of the groove width.

[0014] Optionally, a lead screw is provided on the inner sidewall of the base, the lead screw passes through the two opposite sides of the second plate and forms a thread inside the second plate that mates with the lead screw, and one end of the lead screw extends to the outer sidewall of the base and is connected to a knob.

[0015] By adopting the above technical solution, the lead screw can continuously and smoothly adjust the sliding of the second plate relative to the first plate; the lead screw and the thread have self-locking properties, so that the groove width is not easily changed by vibration during operation after the adjustment is completed, thereby improving the stability of the stop strip fixing spacer.

[0016] Optionally, the surface of the first plate forms a first clearance groove between adjacent first grooves, and the surface of the second plate forms a second clearance groove between adjacent second grooves; the second plate can slide relative to the first plate so that the first clearance groove and the second clearance groove form a clearance gap with adjustable width through relative sliding.

[0017] By adopting the above technical solution, the first clearance groove and the second clearance groove provide space for the passage of other components of the loom, thereby avoiding interference between the components and the stop warp strip fixing spacer during operation, and improving the stability of the stop warp strip fixing spacer; at the same time, the clearance gap is adjustable to accommodate the passage of different types of components.

[0018] Optionally, the depth of the first clearance groove is greater than the depth of the first groove; the depth of the second clearance groove is greater than the depth of the second groove.

[0019] By adopting the above technical solution, the first clearance groove and the second clearance groove provide sufficient space for the component to pass through, avoiding accidental contact or scratching between the component and the stop strip fixed at a shallow depth, thereby improving the reliability of the stop strip fixing spacer.

[0020] Optionally, the stop strip fixing plate further includes a housing, the inner side of which is provided with a sliding groove extending along the height direction of the housing, the inner surface of which is covered with an elastic buffer block, the outer side of which is provided with a guide ridge that cooperates with the sliding groove to slide with the housing, and the base is fixedly connected to the elastic buffer block.

[0021] By adopting the above technical solution, the base is slidably disposed relative to the shell, and the elastic buffer block is disposed between the two, thereby playing a significant buffering and shock absorption role when the loom vibrates at high frequency. During operation, the warp stop frame vibrates at high frequency, driving the shell to vibrate at high frequency. The elastic buffer block converts the kinetic energy of the high-frequency vibration into elastic potential energy and generates elastic deformation. Since the base fixes the warp stop strip, the elastic buffer block provides a restoring force to the shell, pushing the shell to reciprocate relative to the base along the guide ridge. Thus, most of the violent vibration energy transmitted from the warp stop frame to the warp stop strip fixing spacer is absorbed and dissipated by the shell and the elastic buffer block, and further converted into the reciprocating motion of the shell relative to the base. This makes the vibration transmitted to the base smoother and uses the inertia of the base itself to maintain the original position or only vibrate with a small amplitude around the original position, thereby reducing the impact of the warp stop strip fixing spacer on the warp stop strip and extending the service life of the warp stop strip fixing spacer.

[0022] Optionally, the base has protruding fixing members on both sides, and clamping members are movably connected to the fixing members on opposite sides, and the relative distance between the clamping members on opposite sides is adjustable.

[0023] By adopting the above technical solution, the relative distance of the clamping members is adjustable, so that the warp stop strip fixing spacer can be easily installed on warp stop racks of different widths or specifications.

[0024] Optionally, the clamping member has a connecting block protruding from its surface. The connecting block is hollow and fitted with the fixing member. The fixing member has a receiving groove on its side. The receiving groove accommodates a tension spring. The end of the tension spring is fixedly connected to the side wall of the connecting block and the receiving groove, respectively.

[0025] By adopting the above technical solution, the clamping member is connected to the tension spring to provide a continuous preload during the installation of the warp stop strip fixing partition, so that the clamping member can adaptively adjust the relative distance and firmly clamp onto the warp stop frame, and provide sufficient clamping force during the operation of the warp stop frame to prevent the warp stop strip fixing partition from coming loose from the warp stop frame.

[0026] Optionally, the clamping member has a slot formed on the side away from the first plate.

[0027] By adopting the above technical solution, the bayonet can be snapped and fixed to the railing or crossbeam of the warp stop frame, thereby facilitating the installation of the warp stop strip fixing partition onto the warp stop frame.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The groove can be adjusted in width to accommodate warp stop strips with different width specifications, and a tight fit can be achieved with the warp stop strip by continuously adjusting the width;

[0030] 2. The housing is slidably connected to the base, and the base abuts against an elastic buffer block disposed on the inner surface of the housing. In the working state, the elastic buffer block buffers the vibration of the housing, making the vibration of the base more gradual.

[0031] 3. The relative distance between the clamping members is adjustable, so that the clamping members can clamp warp stop frames with different widths. Attached Figure Description

[0039] The present application will be further described in detail below with reference to all the accompanying drawings.

[0040] This application discloses a menstrual strip fixing spacer.

[0041] Please see Figure 1-2This application provides a warp stop strip fixing spacer, comprising a base 1, a first plate 2, and a second plate 3. The base 1 has a groove 11 in its center. The surface of the first plate 2 abuts against the inner surface of the groove 11. One surface of the second plate 3 abuts against the first plate 2, and the other surface abuts against the inner surface of the groove 11, so that both the first plate 2 and the second plate 3 are accommodated within the groove 11, reducing the gap between the first plate 2, the second plate 3, and the groove 11. The second plate 3 can slide relative to the first plate 2 along the length of the groove 11. Through the sliding of the second plate 3, the first groove 21 on the surface of the first plate 2 is blocked by the surface of the second plate 3, and the second groove 31 on the surface of the second plate 3 is blocked by the surface of the first plate 2. Therefore, the warp stop strip can only pass through the area where neither the first groove 21 nor the second groove 31 is blocked. Thus, the first groove 21 and the second groove 31 form adjustable-width grooves through the sliding of the second plate 3 relative to the first plate 2 for the warp stop strip to pass through.

[0042] Specifically, the base 1 can be made of metal, such as aluminum alloy, to obtain high strength and corrosion resistance; or it can be made of engineering plastic, such as polyoxymethylene, which has a low coefficient of friction, thereby reducing the frictional resistance when the first plate 2 and the second plate 3 slide relative to each other.

[0043] The first plate 2 and the second plate 3 can be made of stainless steel to enhance their durability; alternatively, they can be made of hard plastic to reduce their weight.

[0044] In this embodiment, the first groove 21 is a strip-shaped groove that extends from the upper end of the first plate 2 along the height direction of the first plate 2 to the middle, thereby forming a space for the warp strip to pass through. The second groove 31 is also a strip-shaped groove that extends from the upper end of the second plate 3 along the height direction of the second plate 3 to the middle. Both the first plate 2 and the second plate 3 are sheet-like, and their opposing surfaces are parallel, thus the first groove 21 and the second groove 31 are parallel.

[0045] Please see Figure 2-3The inner wall of the base 1 is provided with protruding ribs 12 at intervals along the height direction of the groove 11. The surfaces of the first plate 2 and the second plate 3 near the inner wall of the base 1 are respectively provided with corresponding sliding grooves 34 that cooperate with the protruding ribs 12. The surfaces of the first plate 2 and the second plate 3 that abut each other are respectively provided with complementary slots 23 along the length direction of the groove 11. The cooperation of the protruding ribs 12 and the sliding grooves 34 provides motion guidance and stable support for the first plate 2 and the second plate 3 in the vertical direction, effectively preventing the first plate 2 and the second plate 3 from shaking up and down or tilting during the sliding process; the complementary slots 23 between the first plate 2 and the second plate 3 restrict the separation and torsion of the two in the plane where their surfaces abut. The protruding rib 12 can be integrally formed on the inner wall of the base 1, or it can be fixed by welding or bolt connection. Through the synergistic effect of the two sets of structures, the relative movement of the first plate 2 and the second plate 3 is strictly limited to a single linear degree of freedom along the length of the groove 11, ensuring the smoothness and stability of the groove width adjustment. At the same time, the first plate 2, the second plate 3 and the base 1 form a mortise and tenon structure, making them a tightly integrated whole, thereby improving the structural stability and vibration resistance.

[0046] Specifically, the groove 34 and the slot 23 can both be formed by milling on the surfaces of the first plate 2 and the second plate 3, and the groove 34, the slot 23, and the protrusion 12 can all be formed directly by integral molding. The slot 23 can be a dovetail groove, etc., so as to achieve complementary cooperation between the first plate 2 and the second plate 3.

[0047] A scale 33 extending along the length of the second plate 3 is provided on the surface of the second plate 3 away from the first plate 2. The reading of the scale 33 is used to display the width of the groove. The scale 33 can be etched on the surface of the second plate 3 by means of laser engraving, etc. When the second plate 3 is in the initial position, the 0 mark of the scale 33 coincides with the side of the groove 11. When the second plate 3 slides relative to the first plate 2, the scale line of the scale 33 is blocked by the base 1 as the second plate 3 moves, so that the scale line that coincides with the side of the groove 11 is displayed as the width of the groove. This makes it easy for the operator to read intuitively and quickly adjust the width of the groove to fit the stop strip.

[0048] A lead screw 13 is provided on the inner sidewall of the base 1. The lead screw 13 passes through the opposite sides of the second plate 3 and forms a thread inside the second plate 3 that mates with the lead screw 13. One end of the lead screw 13 extends to the outer sidewall of the base 1 and is connected to a knob 14. The engagement of the lead screw 13 and the thread allows for continuous and smooth adjustment of the sliding distance of the second plate 3 relative to the first plate 2 by rotating the knob 14. At the same time, the lead screw 13 and the thread have self-locking properties, so that after the groove width is adjusted by the lead screw 13, the groove width will not easily change due to vibration. The lead screw 13 can be made of alloy steel to ensure its strength and wear resistance; the surface of the knob can be designed with anti-slip textures for easy operation.

[0049] The surface of the first plate 2 has a first clearance groove 22 formed between adjacent first grooves 21, and the surface of the second plate 3 has a second clearance groove 32 formed between adjacent second grooves 31. The second plate 3 can slide relative to the first plate 2, so that the first clearance groove 22 and the second clearance groove 32 form an adjustable clearance gap through relative sliding. The clearance gap allows other components of the loom to pass through, such as the separating strip used to separate the stop warp pieces to prevent them from interfering with each other, while providing support for other components of the loom to prevent deformation under gravity.

[0050] The depth of the first clearance groove 22 is greater than the depth of the first insert groove 21; the depth of the second clearance groove 32 is greater than the depth of the second insert groove 31, thereby placing the other components of the loom and the stop warp strip in spaces at different heights, so that the stop warp strip and the other components of the loom do not interfere with each other, thus ensuring the smooth operation of the loom.

[0051] The base 1 has protruding fasteners 16 on both sides, which are integrally formed with the base 1. The fasteners 16 have strip-shaped receiving grooves 161 on their sides for accommodating tension springs 162. One end of the tension spring 162 is fixedly connected to the side wall of the receiving groove 161. The fasteners 16 are used to slide and connect to the clamping member 43. One end of the clamping member 43 has a connecting block 431 protruding from it. The connecting block 431 is hollow to form a cavity that can accommodate the fasteners 16.

[0052] In this embodiment, a protrusion 4311 is provided on the inner side of the connecting block 431. The protrusion 4311 passes through the opposite sides of the connecting block 431 and can be clearance-fitted with the receiving groove 161, thereby realizing the sliding connection of the clamping member 43 to the fixing member 16, and the other end of the tension spring 162 is fixedly connected to the protrusion 4311. In the initial state, the surface of the clamping member 43 abuts against the base 1, and the tension spring 162 is in a natural state, without applying tension to the clamping member 43; when the stop-warp strip fixing partition is installed on the stop-warp frame, the clamping member 43 slides on the fixing member 16 to adjust the relative distance between the clamping members 43 on the opposite sides to be suitable for fixing on the stop-warp frame, thereby changing the length of the tension spring 162, so that it has elastic potential energy and applies a continuous clamping force to the clamping member 43, thereby preventing the stop-warp strip fixing partition from loosening from the stop-warp frame.

[0053] Please see Figure 1-3 The stop strip fixing plate also includes a housing 4. The housing 4 protrudes on both sides, giving it a convex shape. One end of the housing 4 has an opening so that the base 1 can be inserted into the housing 4. An observation window is provided on the surface of the housing 4 to allow the operator to observe the scale 33. Simultaneously, a sliding groove 41 is provided on the inner side of the housing 4, and a corresponding guide ridge 15 is provided on the surface of the base 1 to cooperate with the sliding groove 41, allowing the base 1 to slide up and down relative to the housing 4. Please refer to [link to relevant documentation]. Figure 3The inner surface of the shell 4 is covered with elastic buffer blocks 42, and the base 1 is fixedly connected to the elastic buffer blocks 42. In this embodiment, the base 1 can be connected to the elastic buffer blocks 42 by means of bonding or other methods. The elastic buffer blocks 42 can be made of rubber and polyurethane, or composite materials, such as polyurethane as the matrix mixed with glass fiber to improve strength. Under the action of an external force along its own thickness direction, the elastic buffer blocks 42 can undergo elastic deformation from 0% to 100% of its own thickness.

[0054] In this embodiment, the loom generates high-frequency vibrations during operation, which in turn cause the housing 4 to vibrate at a high frequency. The elastic buffer block 42 buffers the high-frequency vibrations transmitted from the housing 4 to the base 1, converting them into elastic potential energy and generating elastic deformation. Since the base 1 fixes the warp stop strip, the position of the base 1 relative to the warp stop strip needs to remain unchanged during the operation of the loom. Therefore, the elastic buffer block 42 provides a restoring force to the outer shell through elastic deformation, causing the outer shell to reciprocate along the guide ridge 15 relative to the base 1 to release the elastic potential energy. At the same time, since the base 1 and the elastic buffer block 42 are fixedly connected, the elastic deformation length generated by the elastic buffer block 42 is equal to the displacement of the reciprocating motion of the outer shell. Most of the intense vibration energy transmitted from the warp stop frame to the warp stop strip fixing spacer is absorbed and dissipated by the housing 4 and the elastic buffer block 42, making the vibration transmitted to the base 1 smoother. The base 1 uses its own inertia to maintain its original position or only vibrates with a small amplitude around its original position. Thus, the first plate 2 and the second plate 3 remain stationary relative to the warp stop strip, achieving a stable fixing effect.

[0055] Please see Figure 4-5 These represent two working states of a stop strip fixing spacer provided in the embodiments of this application. Figure 4 This refers to the minimum width of the groove for fixing the warp strip. Figure 5 The maximum width of the groove for fixing the warp stop strip is defined as follows: When the first plate 2 completely blocks the second groove 31 and the second plate 3 completely blocks the first groove 21, the warp stop strip cannot pass through the first plate 2 and the second plate 3, and the groove width formed by the first groove 21 and the second groove 31 is minimized; when the first plate 2 does not block the second groove 31 and the second plate 3 does not block the first groove 21, in this embodiment, the width of the first groove 21 is set to be equal to the width of the second groove 31, so that the projection of the first groove 21 onto the second plate 3 covers the second groove 31, and the warp stop strip can pass through the first groove 21 and the second groove 31 without obstruction, and the maximum width of the warp stop strip can be set to be equal to the width of the first groove 21 or the second groove 31.

[0056] In this embodiment, the width of the first plate 2 is equal to the width of the groove 11, so that the first plate 2 is stationary relative to the base 1; the width of the second plate 3 is less than the width of the groove 11. By rotating the knob 14 to move the lead screw 13, the second plate 3 moves relative to the first plate 2, so that the first groove 21 is periodically blocked by the second plate 3, and the second groove 31 is periodically blocked by the first plate 2. Thus, the width of the groove formed by the first groove 21 and the second groove 31 changes periodically from 0 to the width of the first groove 21, thereby realizing continuous and smooth adjustment of the groove width of the stop warp strip fixing spacer to be suitable for fixing stop warp strips of different width specifications.

[0057] The implementation principle of the warp stop strip fixing spacer in this application embodiment is as follows: pull the clamping member 43 to adjust the distance between the clamping members 43 on both sides to be suitable for fixing on the warp stop frame, first adjust the groove width to the maximum, insert the warp stop strip, and then rotate the knob 14 to gradually and continuously reduce the groove width until the warp stop strip and the groove are tightly fitted, thereby fixing the warp stop strip.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
