Description

[Technical field]

[0001] The utility model relates to the technical field of cloth spreading machines, in particular to a cloth clamping and stretching machine with good synchronization. [Background technology]

[0002] A cloth-laying machine (i.e., a cloth-spreading machine) usually includes a main clamping machine and a cutting mechanism, wherein the main clamping machine can clamp the ends of the fabric and move a certain distance along the bed, thereby laying a predetermined length of fabric on the bed; the cutting mechanism can cut the laid fabric.

[0003] For example, the Chinese invention patent application with application number CN202211395642.7 discloses a cloth placing and cutting mechanism of a fully automatic cloth spreading machine, which includes a machine head, a cloth pulling clamp that can move forward and backward, a cloth clamping clamp, a cloth feeding active shaft and a driven shaft, and a cutting knife. The cloth pulling clamp and the cutting knife are installed in the same machine head to achieve tension-free cloth spreading. However, the machine head of the cloth placing and cutting mechanism adopts a plurality of pneumatic clamps installed on the crossbeam, and each pneumatic clamp is independently controlled by a cylinder to open and clamp, which not only has poor synchronization but also has high cost; of course, there are also some cloth clamping and pulling machines that use a driving mechanism at one end of a whole row of cloth clamps, and use the driving mechanism to drive the whole row of cloth clamps to open and clamp, but in actual operation, the power output by the driving mechanism will gradually decay during the transmission process, resulting in the inability of the two ends of the whole row of cloth clamps to maintain synchronization, which is not conducive to reliable clamping of the fabric.

[0045] In order to better understand the technical solution of the present utility model, the technical solution of the present utility model will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0046] It should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing these embodiments and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. In addition, the terms "first", "second", etc., etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features.

[0047] See also Figures 1 to 8As shown, the utility model is a cloth clamping and pulling machine 100 with good synchronization, the cloth clamping and pulling machine 100 comprises a clamping and pulling main machine 1, a first driving mechanism 2 and a cloth clamping clamp 3; one end of the clamping and pulling main machine 1 is provided with a supporting structure 11; wherein, the clamping and pulling main machine 1 is movably arranged on a bed (not shown), and the movement of the clamping and pulling main machine 1 can be utilized to realize the pulling of the fabric to a desired length during operation; the first driving mechanism 2 is used to drive the cloth clamping clamp 3 to work; the cloth clamping clamp 3 is used to clamp one end of the fabric, so that when the clamping and pulling main machine 1 moves, the cloth clamping clamp 3 can pull the fabric to move with the clamping and pulling main machine 1; the supporting structure 11 is used to realize the support of the first driving mechanism 2 and the cloth clamping clamp 3;

[0048] The first driving mechanism 2 is arranged in the middle of the supporting structure 11, and a plurality of cloth clamps 3 are spaced apart on both sides of the first driving mechanism 2. The cloth clamps 3 are arranged in a row, and each cloth clamp 3 is connected to the first driving mechanism 2 through a connecting piece 4. The first driving mechanism 2 drives each cloth clamp 3 to synchronously perform an opening operation or a clamping operation.

[0049] Since the clamping and pulling structure of the existing clamping and pulling machine either uses a plurality of independently set pneumatic clamps, or uses a driving mechanism set at one end to drive the whole row of clamping clamps to open and clamp, and the synchronization of the above two methods is poor, it is impossible to ensure that the two sides of the fabric are clamped synchronously, which may cause the fabric to be offset. To this end, the utility model proposes a new technical solution, specifically, the first driving mechanism 2 is set in the middle position of the support structure 11, and a plurality of clamping clamps 3 are arranged at intervals on both sides of the first driving mechanism 2, and each clamping clamp 3 is connected to the first driving mechanism 2 through a connecting member 4, so that in specific operation, the first driving mechanism 2 can be used to drive the clamping clamps 3 on both sides to open or clamp synchronously. Since the first driving mechanism 2 is located in the middle position of the whole row of clamping clamps 3, the power output by the first driving mechanism 2 can be transmitted to both sides synchronously, so that the whole row of clamping clamps 3 can be better synchronized, so that the fabric can be clamped more reliably, and the fabric is not easy to be offset.

[0050] As a specific implementation of the utility model, the first driving mechanism 2 is a double-end output reduction motor. Since the two output ends of the double-end output reduction motor can output synchronously, the cloth clamps 3 located on both sides of the first driving mechanism 2 can be better synchronized.

[0051] More specifically, the connecting member 4 includes a fixed connecting member 41 and a movable connecting member 42 arranged on both sides of the first driving mechanism 2; one end of the fixed connecting member 41 is fixedly connected to the first driving mechanism 2, and the other end of the fixed connecting member 41 is fixedly connected to the supporting structure 11; one end of the movable connecting member 42 is connected to the output end of the first driving mechanism 2, and the other end of the movable connecting member 42 is rotatably connected to the supporting structure 11, so that the movable connecting member 42 can rotate under the drive of the first driving mechanism 2;

[0052] Each of the cloth clamps 3 includes a fixed clamp 31 and a movable clamp 32 that cooperate with each other. Each of the fixed clamps 31 is connected to the fixed connecting member 41 to fix each of the fixed clamps 31. Each of the movable clamps 32 is connected to the movable connecting member 42, so that the movable connecting member 42 can drive each of the movable clamps 32 to rotate. Since the fixed clamp 31 cannot rotate, when the movable connecting member 42 drives the movable clamp 32 to approach the fixed clamp 31, the fabric can be clamped; and when the movable connecting member 42 drives the movable clamp 32 away from the fixed clamp 31, the fabric can be loosened.

[0053] For more details, please refer to Figures 6 to 8 As shown, the connecting member 4 also includes a first auxiliary connecting member 43 and a second auxiliary connecting member 44; the fixed connecting members 41 on both sides are connected together through the first auxiliary connecting member 43, and the fixed clamping jaw 31 is arranged on the first auxiliary connecting member 43; the movable connecting members 42 on both sides are connected together through the second auxiliary connecting member 44, and the movable clamping jaw 32 is arranged on the second auxiliary connecting member 44.

[0054] Since there is a long distance between the two sides of the first driving mechanism 2, if the cloth clamp 3 is not provided between the two sides of the first driving mechanism 2, the middle part of the fabric cannot be clamped; for this reason, the utility model adopts the method of connecting the fixed connecting members 41 on both sides together through the first auxiliary connecting member 43, and connecting the movable connecting members 42 on both sides together through the second auxiliary connecting member 44, and at the same time, a fixed clamping jaw 31 is provided on the first auxiliary connecting member 43, and a movable clamping jaw 32 is provided on the second auxiliary connecting member 44, so that during specific work, the fixed clamping jaw 31 on the first auxiliary connecting member 43 and the movable clamping jaw 32 on the second auxiliary connecting member 44 can be used to cooperate to reliably clamp the middle part of the fabric, and at the same time, the two movable connecting members 42 are connected into one through the second auxiliary connecting member 44, which is conducive to better keeping the movable connecting members 42 on both sides synchronized, thereby further improving the clamping effect.

[0055] As a preferred embodiment of the utility model, the number of the cloth clamps 3 arranged on both sides of the first driving mechanism 2 is equal, and the cloth clamps 3 on both sides are evenly spaced, so that the first driving mechanism 2 is located exactly in the middle of the entire row of cloth clamps 3, which can make the cloth clamps 3 at both ends better maintain synchronization, thereby ensuring that both sides of the fabric can be clamped synchronously.

[0056] In some embodiments of the utility model, the free end of the movable clamping jaw 32 has a clamping portion 321 extending downward to the top of the fixed clamping jaw 31, and the clamping portion 321 is an arc-shaped hook plate structure; the fixed clamping jaw 31 is a strip plate structure. The utility model designs the clamping portion 321 to be an arc-shaped hook plate structure, and designs the fixed clamping jaw 31 to be a strip plate structure, so that the contact area between the fabric and the clamping portion 321 and the fixed clamping jaw 31 can be increased, and the fabric can be reliably clamped without damaging the fabric.

[0057] In some embodiments of the present invention, please refer to Figure 3 As shown, the movable connecting member 42 includes a first driving shaft 421 and a first mounting plate 422, one end of the first driving shaft 421 is connected to the output end of the first driving mechanism 2, and the other end of the first driving shaft 421 is rotatably connected to the supporting structure 11, so that the first driving mechanism 2 can drive the first driving shaft 421 to rotate; the first mounting plate 422 and the first driving shaft 421 are detachably connected, and specifically, the first mounting plate 422 and the first driving shaft 421 can be locked together by screws or bolts, and the movable clamp 32 is installed on the first mounting plate 422.

[0058] In some embodiments of the present invention, please refer to Figure 3 As shown, the fixed connecting member 41 includes a fixed shaft body 411 and a second mounting plate member 412, one end of the fixed shaft body 411 is fixedly connected to the first driving mechanism 2, specifically, one end of the fixed shaft body 411 is fixedly connected to the outer shell of the first driving mechanism 2, and the other end of the fixed shaft body 411 is fixedly connected to the supporting structure 11; the second mounting plate member 412 and the fixed shaft body 411 are detachably connected, specifically, the second mounting plate member 412 and the fixed shaft body 411 can be locked together by screws or bolts, and the fixed clamp 31 and the second mounting plate member 412 are integrally formed, so that on the one hand, the connection strength between the fixed clamp 31 and the second mounting plate member 412 can be ensured, and it can also be convenient to manufacture.

[0059] In some embodiments of the utility model, the cloth clamping and pulling machine 100 also includes a cutting mechanism 5 used in conjunction with the cloth clamping and pulling main machine 1; a plurality of cloth pressing clamps 6 are arranged at intervals on the cutting mechanism 5, and a second driving mechanism 7 is arranged on the cutting mechanism 5, each of the cloth pressing clamps 6 is connected to the second driving mechanism 7, and each of the cloth pressing clamps 6 is driven to perform an opening operation or a pressing operation through the second driving mechanism 7; the cloth pressing clamps 6 and the cloth clamping clamps 3 are staggered with each other. During the specific implementation of the utility model, the cutting mechanism 5 is provided with a cutting tool (not shown) on one side of the surface clamping and pulling main machine 1 which can be movably arranged up and down, and the cloth pressing clamp 6 is arranged below the cutting tool. During operation, when the cloth clamp 3 on the clamping and pulling main machine 1 pulls the fabric and moves to the desired position together with the clamping and pulling main machine 1, the cloth pressing clamp 6 can be used to press the fabric, thereby facilitating the cutting tool to descend and cut the fabric; when the fabric is cut, the cutting tool rises and resets, and the clamping and pulling main machine 1 drives the cloth clamp 3 to move in the direction close to the cloth pressing clamp 6, and controls the cloth clamp 3 to clamp one end of the fabric after it moves into place, and then controls the cloth pressing clamp 6 to release the fabric after clamping, thereby facilitating the clamping and pulling main machine 1 to pull the fabric out to the desired length again.

[0060] Since the cloth pressing clamp 6 needs to wait until the cloth clamping clamp 3 clamps the fabric before it can be released, the utility model adopts a staggered arrangement of the cloth pressing clamp 6 and the cloth clamping clamp 3, so that the cloth clamping clamp 3 will not be affected by the cloth pressing clamp 6 during the process of clamping the fabric, thereby ensuring that the cloth clamping clamp 3 can reliably clamp the fabric.

[0061] In some embodiments of the present utility model, it further includes a first lifting assembly 81, a second lifting assembly 82 and a movable support frame 51;

[0062] The support structure 11 is connected to the clamping and pulling main machine 1 through the first lifting assembly 81; the movable support frame 51 is connected to the cutting mechanism 5 through the second lifting assembly 82, and the cloth pressing clamp 6 and the second driving mechanism 7 are both arranged on the movable support frame 51; the bottom of the movable support frame 51 has a cloth pressing plate 511 extending toward the clamping and pulling main machine 1. In the specific implementation of the utility model, the cutting tool can also be arranged on the movable support frame 51, so that the second lifting assembly 82 can be used to drive the cutting tool to move up and down. As a specific embodiment of the present invention, the first lifting component 81 and the second lifting component 82 may include a slider, a slide rail, a gear, a rack and a lifting drive motor, wherein the support structure 11 or the movable support frame 51 is connected to the slider, the slider is slidably assembled on the slide rail, the slide rail is fixed on the clamping and pulling main machine 1 or the cutting mechanism 5 along the vertical direction, the lifting drive motor is connected to the gear, the rack is fixed on the support structure 11 or the movable support frame 51, and the gear and the rack are meshed, so that the first lifting component 81 can be used to drive the support structure 11 to be lifted and lowered, and the second lifting component 82 can be used to drive the movable support frame 51 to be lifted and lowered; of course, the present invention is not limited to this, and lifting components of other structures can also be used in specific implementations, as long as they can drive the support structure 11 and the movable support frame 51 to move up and down.

[0063] During actual operation, when the clamping and pulling main machine 1 drives the first driving mechanism 2 and the cloth clamping clamp 3 to perform reciprocating motion, the cloth clamping clamp 3 may touch the laid fabric, thereby causing the fabric to become skewed, etc. For this reason, the utility model adopts the method of connecting the supporting structure 11 with the clamping and pulling main machine 1 through the first lifting component 81, so that during specific operation, the first lifting component 81 can be used to drive the supporting structure 11 to be lifted and adjusted, thereby driving the first driving mechanism 2 and the cloth clamping clamp 3 to be lifted and adjusted, thereby ensuring that the cloth clamping clamp 3 does not touch the laid fabric during the reciprocating motion; at the same time, the movable support frame 51 is connected to the cutting mechanism 5 through the second lifting component 82, and the cloth pressing clamp 6 and the second driving mechanism 7 are both arranged on the movable support frame 51, so that during specific operation, the second lifting component 82 can be used to drive the cloth pressing clamp 6 and the second driving mechanism 7 to be lifted and adjusted, so that the cloth pressing clamp 6 and the cloth clamping clamp 3 can better cooperate to realize the functions of clamping, pressing and pulling cloth.

When the cutting tool cuts the fabric, the cloth pressing plate 511 can be used to press the end of the cut fabric downward so that the end of the fabric will not float up or deviate, thereby ensuring the spreading effect.

[0064] In some embodiments of the present invention, please refer to Figure 4 and Figure 5As shown, each of the cloth pressing clamps 6 includes a fixed supporting claw 61 and a movable pressing claw 62 that cooperate with each other;

[0065] The second driving mechanism 7 includes a second driving shaft 71 and a pressing claw driving motor 72. The second driving shaft 71 is rotatably set on the movable support frame 51.
