[0034] As Figures 1-6The utility model discloses an adjustable cloth roller shaft seat, and the adjustable cloth roller shaft seat comprises a fixing frame, a pressing mechanism 30, a pushing mechanism 20 and a spring 6. The fixing frame is fixed on the frame of the loom. The fixing frame comprises a fixing base 10. The fixing base 10 is provided with a first accommodating cavity 11 and a second accommodating cavity 12 which are in communication with each other. The pressing mechanism 30 comprises a first shaft body 32 and a pressing end 31. The pressing end 31 is arranged at the first end of the first shaft body 32. The second end of the first shaft body 32 extends into the first accommodating cavity 11. The first shaft body 32 is provided with a pushing groove 33. The pushing mechanism 20 comprises a rotating body 21 and a pushing pin 22 arranged at the end of the rotating body 21. The pushing pin 22 penetrates through the second accommodating cavity 12 and cooperates with the pushing groove 33. The rotating body 21 is arranged to be rotatable relative to the second accommodating cavity 12 so as to drive the pushing pin 22 to push the first shaft body 32 to move. The spring 6 is arranged in parallel with the first shaft body 32. One end of the spring 6 is pressed against the fixing frame. The other end of the spring 6 is pressed against the second end of the first shaft body 32 so as to push the first shaft body 32 to move along the axial direction thereof.
[0035] In the embodiment, the adjustable cloth roller shaft seat of the utility model can be applied to the loom individually or in pairs. For example, when the loom needs only one adjustable cloth roller shaft seat, the adjustable cloth roller shaft seat is fixed on one side frame of the loom through the fixing frame. The other side frame of the loom needs to be provided with a supporting seat matched with the first end of the cloth roller shaft. The cloth roller shaft is placed between the two side frames and the first end thereof is abutted against the supporting seat of the other side frame. Then, the rotating body 21 of the adjustable cloth roller shaft seat is rotated so that the second end of the first shaft body 32 further compresses the spring 6, thereby ensuring that there is enough space between the two side frames for placing the cloth roller shaft. Next, the force applied to the rotating body 21 is stopped. At this time, the elastic force of the spring 6 pushes the first shaft body 32 to move towards the cloth roller shaft until the pressing end 31 tightly presses the cloth roller shaft between the left and right frames of the loom. When the loom needs to use two adjustable cloth roller shaft seats, the two adjustable cloth roller shaft seats are fixed on the left and right frames through the fixing frames respectively and symmetrically. Then, the cloth roller shaft is placed between the two adjustable cloth roller shaft seats. The rotating body 21 of the two adjustable cloth roller shaft seats is rotated respectively or simultaneously to tightly press the cloth roller shaft. The application mode of the adjustable cloth roller shaft seat of the utility model is various. The application can be carried out according to the specific needs of the customers, and examples are not listed here.
[0036] In the embodiment, the structure of the fixing base 10 is not limited specifically, as long as the first accommodating cavity and the second accommodating cavity are provided and the installation of other parts of the loom is not interfered.
[0037] Optionally, in order to facilitate processing and reduce production cost, the fixing base 10 is provided with a plurality of fixing holes 13. Figures 1-2As shown, the fixed seat 10 comprises a bottom plate 13 for fixing with the frame of the textile machine and a T-shaped tube body 14 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 with the bottom plate 13 by a flange, and the end face of the other end of the first tube body is used for cooperating with the inner end face of the tightening end 31, and the inner cavity of the second tube body forms a second accommodating cavity 12.
[0038] In the embodiment, the first accommodating cavity 11 is used for cooperating with the first shaft body 32 and can meet the movement of the first shaft body in the first accommodating cavity 11 along the axial direction thereof; and the second accommodating cavity 12 is used for passing the poking pin 22 to be inserted into the poking groove 33 of the first shaft body 32.
[0039] In the embodiment, the poking mechanism 20 is rotated relative to the second accommodating cavity 12, and when the rotating body 21 rotates, the whole poking mechanism 20 rotates together with the rotating body 21.
[0040] In the embodiment, the second end of the first shaft body 32 is located in the first accommodating cavity 11 so that the poking groove 33 of the first shaft body 32 is located in the first accommodating cavity 11, and meanwhile, the first shaft body 32 can move back and forth along the axial direction of the first shaft body 32 relative to the first accommodating cavity 11.
[0041] In the embodiment, the end face of the tightening end 31 is used for cooperating with the end face of the cloth roller shaft to tighten the cloth roller shaft. The tightening end 31 is arranged at the first end of the first shaft body 32, and when the cloth roller shaft does not have a bearing arranged thereon, the tightening end 31 needs to be arranged at the end of the first shaft body 32 through a bearing, so as to rotate relative to the first shaft body, thereby ensuring the rotation of the cloth roller shaft during work; when the end of the cloth roller shaft contains a bearing, the tightening end 31 and the first shaft body 32 can be integrally machined and formed, or the separately machined tightening end 31 can be fixed at the end of the first shaft body 32 and cooperates with the outer ring of the bearing of the end of the cloth roller shaft. In specific applications, flexible arrangement can be made according to the on-site requirements.
[0042] Optionally, in order to facilitate machining and installation, the tightening end 31 is rotatably arranged at the end of the first shaft body 32. Preferably, as shown in the figure, Figure 6 the tightening end 21 is arranged at the first end of the first shaft body 32 through a bearing 7, and meanwhile, the outer diameter of the tightening end 31 is greater than the opening of the first accommodating cavity 11, so as to prevent the tightening end from entering the first accommodating cavity and causing the problem of not being easily taken out.
[0043] In the embodiment, the position of the poking pin 22 is away from the central axis of the rotating body 21, so as to ensure that when the rotating body 21 rotates, the poking pin 22 can apply a pushing force to the inner wall of the poking groove 33 to drive the first shaft body 32 to move along the axial direction thereof. The structure of the poking pin 22 is not specifically limited as long as it can drive the first shaft body 32 to move along the axial direction thereof.
[0044] In this embodiment, the type of the poking groove 33 can be set in multiple styles, as long as the groove wall of the poking groove 33 can effectively receive the pressure from the poking pin 22 when the rotating body 21 rotates, and the groove wall of the poking groove 33 can effectively push the poking pin 22 to drive the rotating body 21 to rotate when the spring 6 pushes the first shaft body to move. For example, the poking groove can be a local circumferential groove or a curved groove arranged along the outer circumferential surface of the first shaft body 32, or can be an annular groove coaxial with the first shaft body 32. Preferably, the poking groove 33 is an annular groove, which is convenient to process and form in production, and can also more effectively receive the pressure from the poking pin 22.
[0045] The adjustable cloth roller shaft seat of the utility model can be applied to a loom singly or in pairs in actual use, and the two application modes will be introduced in detail as follows:
[0046] When only one adjustable cloth roller shaft seat of the utility model is needed in actual application, the fixed frame of the adjustable cloth roller shaft seat is first installed on one side of the loom, a supporting seat matched with the second end of the cloth roller shaft is arranged on the other side of the loom, the rotating body 21 of the adjustable cloth roller shaft seat is rotated towards the spring 6, thereby driving the poking pin 22 to rotate, the poking pin 22 rotates to apply a pushing force to the inner wall of the poking groove 33, thereby pushing the first shaft body 32 to further compress the spring 6, the spring 6 is compressed to reserve sufficient space for the cloth roller shaft, the cloth roller shaft is placed between the fixed seat 10 and the supporting seat and the second end of the cloth roller shaft is abutted against the supporting seat of the other side of the loom, and then the force applied to the rotating body 21 is stopped, at this time, the spring 6 pushes the first shaft body 32 to move towards the cloth roller shaft and until the pressing end 31 tightly presses the cloth roller shaft between the left and right racks of the loom, and in the process of pushing the first shaft body 32 to move by the spring 6, the first shaft body 32 drives the rotating body 21 to rotate through the poking pin 22. When it is needed to disassemble the cloth roller from the loom, the rotating body 21 is rotated again towards the spring 6 to further compress the spring by the first shaft body 32, so that the cloth roller is disassembled from the loom.
[0047] When two adjustable cloth roller shaft seats of the utility model are needed in actual application, the fixed frames of the two adjustable cloth roller shaft seats are symmetrically installed on the left and right racks of the loom, and the operation mode of installing the cloth roller on the loom is similar to the above content, which will not be repeated here. The operation mode of the adjustable cloth roller shaft seat of the utility model can also have other modes, and the user can set the specific operation mode according to the own demand.
[0048] From the above, the utility model discloses adjustable cloth roller shaft seat through spring and pushes first axle body and moves to tighten cloth roller axle, so that it can be applicable to different length's cloth roller axle, thereby effectively save production cost, through rotating rotator and drive first axle body compression spring, so that operator can more conveniently dismouting cloth roller axle. The utility model discloses adjustable cloth roller shaft seat not only can realize the time -saving and labor -saving dismouting cloth roller axle, simultaneously still can adapt to multiple different specifications' cloth roller axle.
[0049] Optionally, in order to control the expansion and contraction of the spring 6, the utility model discloses adjustable cloth roller shaft seat further comprises a rotation limiting mechanism for limiting the rotation of the rotator 21, so that the rotator 21 can be switched between the rotation limiting state and the non-rotation limiting state. When the elastic force of the spring 6 pushes the first axle body to move, the rotator 21 will also rotate following the movement of the first axle body, and the rotation of the rotator 21 is prevented by the rotation limiting mechanism, so as to achieve the effect of preventing the spring 6 from continuously pushing the first axle body 32 to move. In this way, the expansion and contraction control of the spring 6 is indirectly realized by the rotation limiting mechanism 5. The rotation limiting state here means that the rotator 21 cannot continue to rotate under the pushing 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 limiting of the rotator 21, so that the rotator 21 continues to rotate under the pushing of the spring 6. For specific rotation limiting, the customer can set according to his own needs, for example, the rotator 21 can be rotation limited when installing the cloth roller axle, and the rotation limiting of the rotator 21 is released when the cloth roller axle is placed, so that the spring 6 pushes the first axle body to compress the cloth roller axle; or the rotator 21 is rotation limited for multiple times when installing the cloth roller axle, and the rotator is rotation limited once for every certain angle, so that the spring 6 pushes the first axle body to move towards the cloth roller axle in multiple times until the top tight end compresses the cloth roller axle.
[0050] The structure of the rotation limiting mechanism can realize the switching of the rotator between the rotation limiting state and the non-rotation limiting state. There are many kinds of rotation limiting mechanisms in the prior art, for example, the rotation limiting mechanism can be a manual bolt, an elastic bolt, etc. When the manual bolt is adopted, the manual bolt can be inserted into the bolt holes of the fixed frame and the rotator at the same time to prevent the relative rotation of the two.
[0051] Furthermore, for ease of operation, the rotation limiting mechanism includes an elastic pin and multiple positioning holes for the elastic pin to be inserted. These positioning holes are circumferentially distributed around the axis of the rotating body 21. The elastic pin is mounted on a fixed frame and the positioning holes are mounted on the actuating mechanism 20, or the elastic pin is mounted on the actuating mechanism 20 and the positioning holes are mounted on the fixed frame. Here, "mounting the positioning holes or elastic pin on the actuating mechanism 20" means mounting the positioning holes or elastic pin on the rotating body 21 or other components fixedly connected to the rotating body 21. Thus, when the spring 6 pushes the first shaft 32 toward the fabric roll shaft, the rotating body 21 rotates along with it, causing the elastic pin to move relative to the positioning holes. When the elastic pin encounters the nearest positioning hole, it directly inserts into that hole, preventing the rotating body from continuing to rotate. At this point, the elastic pin needs to be manually removed from the positioning hole to allow the rotating body to continue rotating. Then, the above operation is repeated when the elastic pin encounters the next positioning hole. The elastic pins make it very convenient for operators to use the rotation limiting mechanism, while the multiple positioning holes allow the first shaft to be tightened or released gradually in stages, increasing the controllability of the operation.
[0052] Preferably, to further facilitate operation, allowing the operator to operate the rotation limiting mechanism simply by rotating the rotating body, the elastic pin is preferably a press-fit ball plunger. The press-fit ball plunger is a standard part and can be purchased directly from the market. Its installation method can be as follows: the press-fit ball plunger is threaded into the threaded hole of the fixed bracket or rotating body. Correspondingly, the rotating body or fixed bracket has multiple positioning holes circumferentially distributed around the central axis of the rotating body for the ball head of the press-fit ball plunger to enter. Specifically, it can be as follows: Figures 5-6 As shown, a press-fit ball plunger is mounted on the fixed base 10. The side of the rotating body 21 located within the second receiving cavity 12 is provided with multiple second positioning holes 210 that mate with the positioning ball head of the press-fit ball plunger. The plunger hole 15 on the fixed base 10 is used to install the press-fit ball plunger.
[0053] Specifically, the plurality of positioning holes include an end positioning hole and an initial positioning hole, and the positions of the end positioning hole and the initial positioning hole can be set as follows: when the push pin 22 follows the rotation of the rotating body 21 to rotate 90° from directly above the central axis of the rotating body 21 to the direction away from the spring 6, the elastic pin is inserted into the end positioning hole, thereby preventing the rotating body 21 from rotating; when the push pin 22 follows the rotation of the rotating body 21 to rotate 90° from directly above the central axis of the rotating body 21 to the direction of the spring 6, the elastic pin is inserted into the initial positioning hole, thereby preventing the rotating body 21 from rotating; and at least one positioning hole for the elastic pin to be inserted is arranged between the end positioning hole and the initial positioning hole. That is, when the elastic pin is inserted into the end positioning hole matched therewith, the spring 6 reaches the maximum length in the working state at this time; and when the elastic pin is inserted into the initial positioning hole matched therewith, the spring 6 reaches the minimum length in the working state at this time. The other positioning holes arranged between the end positioning hole and the initial positioning hole are arranged to realize the phased control of the spring force between the two extreme lengths of the spring, so that the spring force is orderly released or compressed. The number of the other positioning holes between the end positioning hole and the initial positioning hole is set according to actual needs, and preferably, the plurality of positioning holes are arranged in a circumferential array.
[0054] Further, in order to prevent the limit rotation mechanism from failing to limit rotation, the spring force F0 of the spring 6 on the first shaft body 32 in the working state satisfies the following condition: F1≤F0<F2, wherein F1 is the axial force required to push the first shaft body 32 to move away from the spring 6 when the rotating body 21 is in the non-limit rotation state (i.e., the push-in ball head plunger is located between two adjacent positioning holes); and F2 is the axial force required to push the first shaft body 32 to move away from the spring 6 when the rotating body 21 is in the limit rotation state (i.e., the push-in ball head plunger is located in one of the positioning holes). Here, it is explained in detail that when the spring force F0 of the spring 6 on the first shaft body 32 is greater than or equal to F2, the first shaft body 32 is pushed to drive the rotating body 21 to overcome the resistance of the limit rotation mechanism, so that the push-in ball head plunger is out of the positioning hole and continues to rotate with the rotating body 21. Therefore, by setting the spring force F0 of the spring to be less than F2, the problem of the limit rotation mechanism failing to limit rotation can be effectively prevented. Through the above setting, the spring 6 can be indirectly controlled by the limit rotation mechanism 5, so that the first shaft body is pushed to move towards the cloth roller shaft in stages until the end pressing end tightly presses the cloth roller shaft. Through the limit rotation mechanism 5, the controllability of the spring force of the spring 6 is realized.
[0055] Optionally, in order to better limit the spring and prevent it from tilting during stretching, the second end of the first shaft body 32 is provided with a spring hole 320, and the other end of the spring 6 extends into the spring hole 320 and abuts against the bottom of the spring hole 320. In this way, the spring can only push the first shaft body in the axial direction of the first shaft body, effectively preventing the spring from tilting away from the central axis of the first shaft body.
[0056] Further, in order to prevent the spring hole from affecting the stress intensity of the push slot 33 on the first shaft body, as shown in Figure 4 the center axis of the spring hole 320 deviates from the center axis of the first shaft body 32 in a direction away from the rotating body 21. In this way, a sufficient thickness can be ensured between the hole wall of the spring hole and the slot wall of the push slot to withstand the pushing force of the push pin.
[0057] Further, the fixing frame further comprises a spring seat 5, one 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 pressed between the spring seat 5 and the second end of the first shaft body.
[0058] Alternatively, in order to prevent the rotating body 21 from being detached from the second accommodating cavity 12, the fixing frame further comprises a detachment prevention seat 4 to prevent the rotating body 21 from being detached from the second accommodating cavity 12 in the axial direction, the rotating body 21 is provided with a limiting shaft shoulder 211, the detachment prevention seat 4 cooperates with the limiting shaft shoulder 211 and is fixed to the fixing seat 10. The detachment prevention seat 4 presses on the limiting shaft shoulder 211 in the direction of the push pin 22. The detachment prevention seat 4 can effectively prevent the push mechanism 20 from being knocked due to detachment, and further improve the convenience of work.
[0059] Further, as shown in Figure 2 the rotating body 21 comprises a first rotating body and a second rotating body, the first rotating body is relatively rotatably matched with the second accommodating cavity 12, the push pin 22 is arranged on the end face of the first rotating body, and the diameter of the second rotating body is smaller than that of the first rotating body to form the limiting shaft shoulder 211.
[0060] Among them, the structure of the detachment prevention seat 4 can be designed in many ways as long as it can limit the movement of the rotating body 21 along its axis. For example, the detachment prevention seat 4 can be a ring-shaped pressing plate, when the push pin 22 is inserted into the push slot 33, the ring-shaped pressing plate is sleeved on the rotating body 21 and pressed on the limiting shaft shoulder 211, and then fixedly connected with the fixing seat 10 to realize the axial limitation of the rotating body 21. The structure of the detachment prevention seat 4 also has many in the prior art, which will not be described here.
[0061] Preferably, as shown in Figures 1-3 when the above-mentioned detachment prevention seat 4 is used to prevent the rotating body 21 from being detached from the second accommodating cavity 12, the push mechanism 20 further comprises a limiting body 24 fixedly connected with the rotating body 21, the detachment prevention seat 4 is located between the limiting body 24 and the limiting shaft shoulder 211, wherein after the detachment prevention seat 4 abuts against the limiting shaft shoulder 211 and is fixed to the fixing seat 10, the limiting body 24 is fixedly connected with the rotating body 21, the press-in type ball head plunger is arranged on the end of the limiting body 24 facing the detachment prevention seat 4, and a plurality of first positioning holes 40 are formed on the detachment prevention seat 4 and matched with the positioning ball heads of the press-in type ball head plunger.
[0062] Optionally, the knob mechanism 20 further comprises a handle 23 for driving the rotation of the rotating body 21, and the rotating body 21 can be easily rotated through the lever principle.
[0063] Further, when the above-mentioned embodiment of the rotation limiting structure as shown in Figures 1-3 is selected, the handle 23 is arranged on the limiting body 24, and preferably, the handle 23 is fixedly connected with the limiting body 24 through screw threads.
[0064] Further, when the above-mentioned embodiment of the rotation limiting structure as shown in Figures 5-6 is selected, the handle 23 is arranged on the rotating body 21, and preferably, the handle 23 is fixedly connected with the rotating body 21 through screw threads.
