[0041] like Figure 1-6 As shown, an embodiment of the present invention provides a cloth winding roller seat, which includes a fixing frame, a tightening mechanism 30, a toggle mechanism 20 and a spring 6; the fixing frame is fixed to the frame of the loom, and the fixing frame includes a fixing seat 10, and the fixing seat 10 is provided with a first accommodating cavity 11 and a second accommodating cavity 12 that are interconnected; the tightening mechanism 30 includes a first shaft body 32 and a tightening end 31, and the tightening end 31 is arranged at the first end of the first shaft body 32, and the second end of the first shaft body 32 extends into the first accommodating cavity 11, and the first shaft body 32 is provided with a first accommodating cavity 12. 2 is provided with a toggle groove 33; the toggle mechanism 20 includes a rotating body 21 and a toggle pin 22 arranged at the end of the rotating body 21, the toggle pin 22 passes through the second accommodating cavity 12 and cooperates with the toggle groove 33; the rotating body 21 is configured to be able to rotate relative to the second accommodating cavity 12 to drive the toggle pin 22 to push the first shaft body 32 to move; the spring 6 and the first shaft body 32 are arranged parallel to each other, one end of the spring 6 presses against the fixing frame, and the other end of the spring 6 presses against the second end of the first shaft body 32 to push the first shaft body 32 to move along its axial direction.

[0042] In this embodiment, the cloth rolling roller seat of the present invention can be applied to the loom individually or in pairs. For example, when the loom only needs one cloth rolling roller seat, the cloth rolling roller seat is fixed to one side frame of the loom through its fixing frame, and the other side frame of the loom needs to be provided with a support seat that matches the first end of the cloth rolling roller, and the cloth rolling roller is placed between the two side frames and the first end of the cloth rolling roller is against the support seat of the other side frame, and then the rotating body 21 of the cloth rolling roller seat is rotated so that the second end of the first shaft body 32 further compresses the spring 6 to ensure that there is enough space between the two frames to place the cloth rolling roller. Then, stop applying force to the rotating body 21. At this time, the elastic force of the spring 6 pushes the first shaft 32 toward the cloth roller until the tightening end 31 tightens the cloth roller between the left and right frames of the loom; when the loom needs to use two cloth roller seats, the two cloth roller seats are symmetrically fixed on the left and right frames through the fixing frame, and then the cloth roller is placed between the two cloth roller seats, and then the rotating bodies 21 of the two cloth roller seats are rotated separately or simultaneously to tighten the cloth roller. The utility model has a variety of application methods, which can be applied according to the specific needs of customers, and examples are not given here one by one.

[0043] In this embodiment, the structure of the fixing seat 10 is not specifically limited, as long as it has the above-mentioned first accommodating cavity and the second accommodating cavity and can be stably installed on the frame of the loom without interfering with the installation of other components of the loom.

[0044] Optionally, in order to facilitate processing and reduce production costs, such as Figure 1-2As shown, the fixing seat 10 includes a bottom plate 13 and a T-shaped tube body 14. The bottom plate 13 is used to be fixed to the frame of the textile machine. The T-shaped tube body 14 is welded by a first tube body and a second tube body. The inner cavity of the first tube body forms a first accommodating cavity 11. One end of the first tube body is welded to the bottom plate 13 through a flange. The end face of the other end of the first tube body is used to cooperate with the inner end face of the tightening end 31. The inner cavity of the second tube body forms a second accommodating cavity 12.

[0045] In this embodiment, the first accommodating cavity 11 is used to cooperate with the first shaft body 32 and can satisfy the axial movement of the first shaft body in the first accommodating cavity 11; the second accommodating cavity 12 is for the push pin 22 to pass through and be inserted into the push groove 33 of the first shaft body 32.

[0046] In this embodiment, the second end of the first shaft body 32 is located in the first accommodating cavity 11 so that the shifting groove 33 of the first shaft body 32 is located in the first accommodating cavity 11, and the first shaft body 32 can move forward and backward along the axial direction of the first shaft body 32 relative to the first accommodating cavity 11.

[0047] In this embodiment, the end surface of the tightening end 31 is used to cooperate with one end surface of the cloth rolling roller to tighten the cloth rolling roller. The tightening end 31 is set at the first end of the first shaft 32. When the cloth rolling roller itself is not provided with a bearing, the tightening end 31 needs to be set at the end of the first shaft 32 through the bearing, so that it can rotate relative to the first shaft, thereby ensuring the rotation of the cloth rolling roller during operation; when the end of the cloth rolling roller includes a bearing, the tightening end 31 and the first shaft 32 can be integrally formed, or the separately processed tightening end 31 can be fixed to the end of the first shaft 32 and cooperate with the outer ring of the bearing at the end of the cloth rolling roller. In specific applications, it can be flexibly set according to on-site needs.

[0048] Optionally, in order to facilitate processing and installation, the pressing end 31 is rotatably arranged at the end of the first shaft body 32. Figure 6 As shown, the tightening end 21 is installed on the first end of the first shaft body 32 through the bearing 7. At the same time, the outer diameter of the tightening end 31 is larger than the opening of the first accommodating cavity 11 to prevent the tightening end from entering the first accommodating cavity and causing the problem of being difficult to remove.

[0049] In this embodiment, the position of the toggle pin 22 is set away from the central axis of the rotating body 21, so that when the rotating body 21 rotates, the toggle pin 22 can apply thrust to the inner wall of the toggle slot 33 to drive the first shaft body 32 to move along its axial direction. The structure of the toggle pin 22 is not specifically limited as long as it can toggle the first shaft body 32 to move along its axial direction.

[0050] In this embodiment, the type of the toggle groove 33 can be set to a variety of styles, as long as it can meet the requirements that when the rotating body 21 rotates, the groove wall of the toggle groove 33 can effectively bear the pressure from the toggle pin 22, and when the spring 6 pushes the first shaft body to move, the groove wall of the toggle groove 33 can effectively push the toggle pin 22 to drive the rotating body 21 to rotate. For example, the toggle groove can be a local surrounding groove or a curved groove set along the outer circumference of the first shaft body 32, or it can be an annular groove coaxial with the first shaft body 32. Preferably, the toggle groove 33 is an annular groove, which is easy to process and shape during production, and can also more effectively bear the pressure from the toggle pin 22.

[0051] When the cloth rolling roller seat of the present invention is used specifically, it can be applied to a loom individually or in pairs as described above. The following will introduce these two usage modes in detail:

[0052] When only one cloth-winding roller seat of the present invention is needed in practical applications, the fixing frame of the cloth-winding roller seat is first installed on one side frame of the loom, and a supporting seat matching with the second end of the cloth-winding roller shaft is required to be provided on the frame on the other side of the loom, and the rotating body 21 of the cloth-winding roller seat is rotated in the direction of the spring 6, thereby driving the toggle pin 22 to rotate. The rotation of the toggle pin 22 will apply a thrust to the inner wall of the toggle groove 33, thereby pushing the first shaft body 32 to further compress the spring 6. After the spring 6 is compressed, it can be Place the cloth roller shaft with enough space, place the cloth roller shaft between the fixed seat 10 and the support seat and make its second end abut against the support seat of the frame on the other side, then stop applying force to the rotating body 21, at this time, the spring 6 will push the first shaft body 32 to move toward the cloth roller shaft until the top end 31 tightens the cloth roller shaft between the left and right frames of the loom, and at the same time, when the spring 6 pushes the first shaft body 32 to move, the first shaft body 32 will also drive the rotating body 21 to rotate through the toggle pin 22. When it is necessary to remove the cloth roller from the loom, it is only necessary to rotate the rotating body 21 again toward the direction of the spring 6 to further drive the first shaft body 32 to compress the spring, so that the cloth roller can be removed from the loom.

[0053] When two cloth rolling roller seats of the present invention are needed in actual use, the fixing frames of the two cloth rolling roller seats are symmetrically installed on the left frame and the right frame of the loom, and the operation method of installing the cloth rolling roller on the loom is similar to the above content, which will not be repeated here. The cloth rolling roller seat of the present invention can also have other various operation methods, and the user can set the specific operation method according to their own needs.

[0054] As can be seen from the above content, the cloth rolling roller seat of the present invention tightens the cloth rolling roller by pushing the first shaft body to move through the spring, so that it can be applied to cloth rolling rollers of different lengths, thereby effectively saving production costs; by rotating the rotating body to drive the first shaft body to compress the spring, the operator can more conveniently disassemble and assemble the cloth rolling roller. The cloth rolling roller seat of the present invention can not only realize time-saving and labor-saving disassembly and assembly of the cloth rolling roller, but also can adapt to a variety of cloth rolling rollers of different specifications.

[0055] Optionally, in order to control the extension and retraction of the spring 6, the cloth rolling roller seat of the present invention also includes a rotation limiting mechanism for limiting the rotation of the rotating body 21 so that the rotating body 21 can switch between a rotation limiting state and a non-rotation limiting state. When the elastic force of the spring 6 pushes the first shaft body to move, the rotating body 21 will also rotate following the movement of the first shaft body, and the rotation of the rotating body 21 is prevented by the rotation limiting mechanism, thereby preventing the spring 6 from continuing to push the first shaft body 32 to move. In this way, the extension and retraction control of the spring 6 can be indirectly achieved through the rotation limiting structure. The rotation limiting state here means that the rotating body 21 cannot continue to rotate under the push of the spring 6 under the action of the rotation limiting mechanism; and the non-rotation limiting state means that the rotation limiting mechanism releases the rotation restriction on the rotating body 21, so that the rotating body 21 continues to rotate under the push of the spring 6. As for how to limit the rotation specifically, the customer can set it according to his own needs. For example, when installing the cloth roller, the rotating body 21 can be limited in rotation. When the cloth roller is placed, the rotation limit of the rotating body 21 is released so that the spring 6 pushes the first shaft to press the cloth roller; or when installing the cloth roller, the rotating body 21 can be limited in rotation multiple times, and the rotating body is limited in rotation once every time it rotates a certain angle, so that the spring 6 pushes the first shaft toward the cloth roller for multiple times until the tightening end presses it.

[0056] The structure of the rotation limiting mechanism only needs to be able to allow the rotating body to switch between the rotation limiting state and the non-rotation limiting state. There are many types of rotation limiting mechanisms in the prior art, for example, the rotation limiting mechanism can be a manual latch, an elastic latch, etc. When a manual latch is used, the manual latch can be inserted into the latch holes of the fixed frame and the rotating body to prevent the two from rotating relative to each other.

[0057] Furthermore, in order to facilitate operation, the rotation limiting mechanism includes an elastic pin and a plurality of positioning holes for inserting the elastic pin, and the plurality of positioning holes are circumferentially distributed around the axis of the rotating body 21, and the elastic pin is arranged on the fixing frame and the positioning hole is arranged on the rotating body 21, or the elastic pin is arranged on the rotating body 21 and the positioning hole is arranged on the fixing frame. In this way, when the spring 6 pushes the first shaft body 32 to move toward the cloth winding roller, the rotating body 21 rotates together, so that the elastic pin and the positioning hole move relative to each other, and the elastic pin directly inserts into the positioning hole after encountering the nearest positioning hole, thereby preventing the rotating body from continuing to rotate. At this time, the elastic pin needs to be manually disengaged from the positioning hole to allow the rotating body to continue to rotate, and then the elastic pin encounters the next positioning hole and repeats the above operation again. The elastic pin makes it very convenient for the operator to use the rotation limiting mechanism, and the setting of the plurality of positioning holes enables the first shaft body to gradually tighten or release the cloth winding roller in stages, thereby increasing the controllability of the operation.

[0058] Preferably, in order to further facilitate the operation, so that the operator can operate the rotation limiting mechanism only by rotating the rotating body, the elastic pin is preferably a press-in ball plunger. The press-in ball plunger is a standard part and can be purchased directly on the market. The installation method can be as follows: the press-in ball plunger is fixed to the threaded hole of the fixed frame or the rotating body by threads. Correspondingly, the rotating body or the fixed frame is provided with a plurality of positioning holes distributed around the central axis of the rotating body 21 for the ball head of the press-in ball plunger to enter. Specifically, it can be as follows Figure 5-6 As shown, the press-in ball plunger is arranged on the fixing seat 10, and the side of the rotating body 21 located in the second accommodating cavity 12 is provided with a plurality of second positioning holes 210 which cooperate with the positioning ball head of the press-in ball plunger. Among them, the plunger hole 15 on the fixing seat 10 is used to install the press-in ball plunger.

[0059] Specifically, the multiple positioning holes include a terminal positioning hole and an initial positioning hole. The positions of the terminal positioning hole and the initial positioning hole can be set as follows: When the toggle pin 22 rotates 90° away from the spring 6 following the rotating body 21 from directly above the central axis of the rotating body 21, the elastic pin is inserted into the terminal positioning hole, thereby preventing the rotating body 21 from rotating; when the toggle pin 22 rotates 90° towards the spring 6 following the rotating body 21 from directly above the central axis of the rotating body 21, the elastic pin is inserted into the initial positioning hole, thereby preventing the rotating body 21 from rotating; at least one positioning hole into which the elastic pin can be inserted is provided between the terminal positioning hole and the initial positioning hole. That is, when the elastic pin is inserted into the terminal positioning hole that mates with it, the spring 6 reaches its maximum length during operation; when the elastic pin is inserted into the initial positioning hole that mates with it, the spring 6 reaches its shortest length during operation. Other positioning holes are provided between the terminal positioning hole and the initial positioning hole to control the spring force in stages between the two extreme lengths of the spring, so that the spring force is released or compressed in an orderly manner. The number of other positioning holes between the terminal positioning hole and the initial positioning hole is set according to actual requirements, and preferably, the multiple positioning holes are arranged in a circular array.

[0060] Furthermore, to prevent the rotation limiting mechanism from failing to limit rotation, the elastic force F0 of the spring 6 on the first shaft body 32 satisfies the following conditions during the working state: F1 ≤ F0 < F2, where F1 is the axial force required to push the first shaft body 32 away from the spring 6 when the rotating body 21 is in a non-rotation-limiting state (i.e., when the press-in ball head plunger is between two adjacent positioning holes); where F2 is the axial force required to push the first shaft body 32 away from the spring 6 when the rotating body 21 is in a rotation-limiting state (i.e., when the press-in ball head plunger is in one of the positioning holes). Here, to explain in more detail, when the elastic force F0 of the spring 6 on the first shaft body 32 is greater than or equal to F2, it will push the first shaft body 32 to drive the rotating body 21 to overcome the resistance of the rotation limiting mechanism, causing the press-in ball head plunger to脱出 from the positioning hole and continue to rotate following the rotating body 21. Therefore, setting the elastic force F0 of the spring to be less than F2 can effectively prevent the problem of the rotation limiting mechanism failing to limit rotation. Through the above settings, the spring 6 can be effectively controlled indirectly by the rotation limiting mechanism 5, and the first shaft body can be pushed towards the cloth winding roller shaft in stages until the tightening end tightly clamps the cloth winding roller shaft. The controllability of the elastic force of the spring 6 is achieved through the rotation limiting mechanism 5.

[0061] Optionally, to better limit the spring and prevent it from tilting during telescoping, a spring hole 320 is provided at the second end of the first shaft body 32, and one end of the spring 6 extends into the spring hole 320 and abuts against the bottom of the spring hole 320. This enables the spring to only push the first shaft body along the axial direction of the first shaft body, effectively preventing the spring from tilting in a direction deviating from the central axis of the first shaft body.

[0062] Furthermore, in order to prevent the spring hole from affecting the force strength of the toggle slot 33 on the first shaft body, as Figure 4 As shown, the central axis of the spring hole 320 deviates from the central axis of the first shaft body 32 in a direction away from the rotating body 21. This ensures that the hole wall of the spring hole and the groove wall of the toggle groove have sufficient thickness to withstand the toggle force of the toggle pin.

[0063] Further, the fixing frame further comprises a spring seat 5, the other end of the spring 6 is fixed to the spring seat 5, and the spring seat 5 is fixed to the fixing seat 10. In this way, the spring is squeezed between the spring seat 5 and the second end of the first shaft body 32.

[0064] Optionally, in order to prevent the rotating body 21 from being separated from the second accommodating chamber 12, the fixing frame further includes an anti-disengagement seat 4 to prevent the rotating body 21 from being separated from the second accommodating chamber 12 along its axial direction. A limiting shoulder 211 is provided on the rotating body 21, and the anti-disengagement seat 4 cooperates with the limiting shoulder 211 and is fixed to the fixing seat 10. The anti-disengagement seat 4 presses on the limiting shoulder 211 in the direction of the toggle pin 22. The anti-disengagement seat 4 can effectively prevent the toggle mechanism 20 from being knocked due to falling off, and further improves the convenience of work.

[0065] Furthermore, if Figure 2 As shown, the rotating body 21 includes a first rotating body and a second rotating body. The first rotating body and the second accommodating cavity 12 can cooperate with each other in relative rotation. The driving pin 22 is arranged on the end surface of the first rotating body. The diameter of the second rotating body is smaller than that of the first rotating body to form a limiting shoulder 211.

[0066] The structure of the anti-slip seat 4 can be designed in various ways, as long as it can limit the movement of the rotating body 21 along its axis. For example, the anti-slip seat 4 can be an annular pressure plate. After the toggle pin 22 is inserted into the toggle groove 33, the annular pressure plate is sleeved on the rotating body 21 and pressed on the limiting shoulder 211, and then fixedly connected to the fixed seat 10 to achieve axial limiting of the rotating body 21. There are many structures of the anti-slip seat 4 in the prior art, which will not be described one by one here.

[0067] Preferably, it is also possible to Figure 1-3 As shown, when the above-mentioned anti-detachment seat 4 is used to prevent the rotating body 21 from detaching from the second accommodating chamber 12, the toggle mechanism 20 also includes a limiting body 24 fixedly connected to the rotating body 21, and the anti-detachment seat 4 is located between the limiting body 24 and the limiting shoulder 211, wherein after the anti-detachment seat 4 abuts against the limiting shoulder 211 and is fixed to the fixed seat 10, the limiting body 24 is fixedly connected to the rotating body 21, and a press-in ball head plunger is arranged at the end of the limiting body 24 facing the anti-detachment seat 4, and a plurality of first positioning holes 40 that cooperate with the positioning ball heads of the press-in ball head plungers are opened on the anti-detachment seat 4.

[0068] Optionally, the toggling mechanism 20 further includes a handle 23 for driving the rotating body 21 to rotate, and the effect of easily rotating the rotating body 21 can be achieved through the lever principle.

[0069] Further, when the above-described implementation manner of the rotation-limiting structure as Figure 1-3 shown is selected, the handle 23 is provided on the limiting body 24. Preferably, the handle 23 is fixedly connected to the limiting body 24 by a thread.

[0070] Further, when the above-described implementation manner of the rotation-limiting structure as Figure 5-6 shown is selected, the handle 23 is provided on the rotating body 21. Preferably, the handle 23 is fixedly connected to the rotating body 21 by a thread. At the same time, in order to avoid the situation that the handle 23 does not have enough rotation space when rotating the handle 23, the handle 23 can be set to be inclined at a certain angle away from the fixed seat 10.

[0071] An embodiment of the present invention also discloses a loom, including two of the above-described cloth winding roller shaft seats. The two cloth winding roller shaft seats are respectively installed on the left and right side frames of the loom to jointly clamp the cloth winding roller shaft. In this way, by adjusting the two cloth winding roller shaft seats, more different specifications of cloth winding roller shafts can be used for the loom. The loom of the present invention can not only achieve convenient and efficient disassembly and assembly of the cloth winding roller shaft through the above-described cloth winding roller shaft seat, but also adapt to various specifications of cloth winding roller shafts.

[0072] An embodiment of the present invention also discloses an installation method of a cloth winding roller shaft. Installing the cloth winding roller shaft on the above-described loom includes the following method steps:

[0073] a) Perform the following operations on the cloth winding roller shaft seats located on both sides of the frame respectively: Rotate the rotating body 21 in the direction of the spring 6 through the handle 23, so that the press-in ball plunger enters the initial positioning hole to reserve enough space for installing the cloth winding roller shaft.

[0074] b) First, determine the length L of the cloth winding roller shaft to be clamped. When D2 < L < D1, select to enter the following step c; when D3 < L ≤ D2, enter the following step d; when L ≥ D1 or L ≤ D3, the length of the cloth winding roller shaft does not meet the requirements of the loom for the specifications of the cloth winding roller shaft and cannot be used in the above-described loom.

[0075] Wherein, when the press-in type ball plungers of the two fabric winding roller seat assemblies respectively enter the corresponding initial positioning holes, the distance between the two tightening ends 31 is D1; when the press-in type ball plunger of one fabric winding roller seat assembly enters the corresponding initial positioning hole and the press-in type ball plunger of the other fabric winding roller seat assembly enters the corresponding end positioning hole, the distance between the tightening ends 31 of the two fabric winding roller seat assemblies is D2; when the press-in type ball plungers of the two fabric winding roller seat assemblies respectively enter the corresponding end positioning holes, the distance between the two tightening ends 31 is D3;

[0076] c) When the determination result according to step b above is D2 < L < D1, abut one end of the fabric winding roller against the tightening end 31 of one of the fabric winding roller seat assemblies, and then rotate the handle 23 of the other fabric winding roller seat assembly in the direction of the fabric winding roller to release the press-in type ball plunger from the restriction of the initial positioning hole, and then rotate along with the rotating body 21 under the thrust of the spring 6. If the fabric winding roller is clamped between the two fabric winding roller seat assemblies before the press-in type ball plunger enters the next positioning hole, the installation is completed; if the press-in type ball plunger enters the next positioning hole under the thrust of the spring 6 and the fabric winding roller is not yet clamped, repeat the above operation, rotate the handle 23 again to release the press-in type ball plunger from the restriction of this positioning hole, and then continue to rotate along with the rotating body 21 under the thrust of the spring 6 until the fabric winding roller is clamped between the two fabric winding roller seat assemblies. Since the length L of the fabric winding roller satisfies D2 < L < D1, when the press-in type ball plunger rotates along with the rotating body 21, the fabric winding roller can be clamped between the two fabric winding roller seat assemblies before the press-in type ball plunger enters the end positioning hole.

[0077] d) When the determination result according to step b above is D3 < L ≤ D2, rotate the handle 23 of one of the fabric winding roller seat assemblies in the direction of the fabric winding roller to rotate the press-in type ball plunger and finally make it enter the end positioning hole, then abut one end of the fabric winding roller against the tightening end 31 of this fabric winding roller seat assembly, and then, in the same operation method as in step c above, rotate the handle 23 of the other fabric winding roller seat assembly in the direction of the fabric winding roller to release the press-in type ball plunger from the restriction of the initial positioning hole and rotate it towards the next positioning hole. If the fabric winding roller is clamped between the two fabric winding roller seat assemblies before the press-in type ball plunger enters the next positioning hole, the installation is completed; if the press-in type ball plunger enters the next positioning hole under the thrust of the spring 6 and the fabric winding roller is not yet clamped, repeat the above operation, continue to rotate the handle 23 to release the press-in type ball plunger from the restriction of the positioning hole until the fabric winding roller is clamped between the two fabric winding roller seat assemblies, then the installation is completed. Since the length L of the fabric winding roller satisfies D3 < L ≤ D2, when the press-in type ball plunger rotates along with the rotating body 21, the fabric winding roller can be clamped between the two fabric winding roller seat assemblies before the press-in type ball plunger of the other fabric winding roller seat assembly enters the end positioning hole.

[0078] The installation method of the cloth rolling roller of the present invention can effectively adopt the corresponding installation method for cloth rolling rollers of various specifications by determining the length of the cloth rolling roller in advance before installation, thereby saving debugging time and making the installation of the cloth rolling roller simpler and more effective.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
