[0002] The cloth winding machine is an important component of the circular knitting machine, which is used to wind up the woven fabric. When enough cloth is wound around a roll core, the machine needs to be stopped to change rolls. The existing roll changing method mainly relies on manual processing, manually cutting the cloth, taking the cloth roll out of the cloth winding machine, and then placing a new roll core, pre-winding the cut cloth around the roll core for one circle to position the roll, and finally restarting the equipment. The existing roll changing process is cumbersome and labor-intensive. Although there are some equipment on the market that assists in cutting and transporting cloth rolls, the roll positioning still needs to rely on manual processing to meet the requirements of cloth roll uniformity. How to design a cloth winding machine that can realize a fully automatic roll changing process has become the problem to be solved in this case. Summary of the invention

[0031] The cloth pressing mechanism 4 includes a pressing wheel 41, an inserting plate 42, and a cloth pressing drive 43.

[0033] The core feeding mechanism 6 is provided with two groups and is respectively arranged at the two ends of the winding mechanism 1, including a material preparation trough 61, a core feeding swing plate 62, and a clamp 63. The two material preparation troughs 61 are used to set up and place the spare core A, the two groups of core feeding swing plates 62 are used to move the core A in the material preparation trough 61 to the clamp 63, and the two groups of clamps 63 are used to clamp the core A and move the core A to the winding mechanism 1.

[0034] The present application will be further described below with reference to a specific working process.

[0035] The knitting parts of the circular knitting machine weave the fabric and transport it downward. After the processes of opening and spreading, the fabric is driven by the fabric winding machine to be wound on the winding core A. After the equipment has been running for a period of time, enough fabric is wound on the winding core A to form a fabric roll, and the circular knitting machine stops and performs automatic roll changing.

[0036] Pushing step: the pushing drive 52 drives the pushing plate 51 to move upward, and the pushing plate 51 passes through the two winding rollers 11 from bottom to top. The inclined surface 511 on the pushing plate 51 pushes the cloth roll upward, and under the guidance of the inclined surface 511, the cloth roll separates from the winding mechanism 1 and rolls out toward the cloth cutting mechanism 2, and then the pushing plate 51 descends and resets.

[0037] Positioning cloth clamping step: the two sets of cloth clamping mechanisms 3 move synchronously, and through the coordinated action of the lifting drive 314 and the swing drive 312, the clamping claws 32 are moved to the side of the cloth between the winding mechanism 1 and the cloth cutting mechanism 2, the telescopic drive 313 extends and the clamping claws 32 are closed, so that both sides of the cloth are clamped by the two sets of clamping claws 32.

[0038] Cloth cutting steps: At this time, there is a layer of cloth corresponding to the top of the cloth cutting mechanism 2, and the transverse movement mechanism 22 drives the cutting knife 21 to move horizontally. The cloth is guided to the electric saw blade 211 through the guide plate 212. During the movement, the electric saw blade 211 cuts and separates the cloth horizontally; the cut cloth rolls are taken away by the automatic robot.

[0039] Core feeding step: A number of cores A are stored in the material preparation trough 61, and the core feeding swing plate 62 swings to one end of the material preparation trough 61 to obtain a core A, and then swings to the clamp 63 to transfer the core A to be clamped by two groups of clamps 63. The clamp 63 descends and moves the core A to be placed on the two winding rollers 11 of the winding mechanism 1.

[0040] Cloth clamping and turning over step: through the coordinated action of the lifting drive 314 and the swing drive 312, the clamping claw 32 is moved to the upper position on the inner side of the winding mechanism 1, and then the clamping claw 32 releases the cloth and retracts through the telescopic drive 313, at which time the cloth is wrapped around the winding core A; Rolling up step: the cloth pressing drive 43 drives the crossbeam 432 to move obliquely toward the winding mechanism 1, so that the pressing wheel 41 presses the cloth toward the winding core A, and at the same time, the pressing edge 421 of the insert plate 42 inserts the cloth between the winding core A and the winding roller 11, and the winding roller 11 rotates and drives the winding core A to rotate, so that the cloth is wound around the winding core A, and then the cloth pressing drive 43 retracts and resets; Cloth rolling steps: The circular knitting machine is started to weave, and the woven cloth roll is driven by the cloth rolling machine to be wound on the winding core A.

[0041] Example 2, reference Figure 8-Figure 10 As shown, the difference between the second embodiment and the first embodiment in structure is that an elastic element 44 is arranged between the pressing wheel 41 and the cross beam 432, and the elastic element 44 makes the pressing wheel 41 have a contraction movement amount toward the cross beam 432 when being squeezed, and the elastic element 44 provides elastic force for the pressing wheel 41 to reset. When the elastic element 44 is in the restored extended state, the farthest end of the pressing wheel 41 is in an outward position relative to the pressing edge 421 of the plug plate 42 in the extended direction; when the elastic element 44 is in the compressed and contracted state, the farthest end of the pressing wheel 41 is in an inward position relative to the pressing edge 421 of the plug plate in the extended direction.

[0042] The elastic element 44 is a device with elastic recovery function such as a spring, a spring with a guide rod, a spring cylinder, a buffer, an elastic block, etc. In the second embodiment, the elastic element is taken as an example of a spring with a guide rod.

[0043] The difference between the working steps of the second embodiment and the first embodiment is that the rolling steps are different.

[0044] In the rolling step, the material pushing drive 52 drives the material pushing plate 51 to rise a certain distance and then stops. The material pushing plate 51 lifts the core A upward for a short distance, which forms a gap between the winding roller A and a winding roller 11. The gap width is 1mm-5mm. The cloth pressing drive 43 drives the crossbeam 432 to extend obliquely toward the direction of the winding mechanism 1. When the pressing wheel 41 presses the cloth toward the core A, the cloth pressing drive 43 continues to move, and the pressing wheel 41 keeps pressing the cloth. The elastic element 44 contracts under pressure. At this time, the insert plate 42 continues to move between the core A and the winding roller 11, so that the pressing edge 421 of the insert plate 42 inserts the cloth into the gap between the core A and the winding roller 11, and then the cloth pressing drive 43 stops extending; the cloth pressing drive 43 retracts, driving the crossbeam 432 to retract a distance and then stop. During this process, the elastic element 44 partially recovers to keep the pressing wheel 41 in a state of pressing the cloth, but the insert plate 42 is pulled out from between the winding core A and the winding roller 11, and the cloth remains in the gap; the pushing drive 52 drives the pushing plate 51 to descend, and the winding core A descends to be supported by the winding roller 11; the winding roller 11 rotates and drives the winding core A to rotate, so that the cloth is wound around the winding core A; the cloth pressing drive 43 retracts again to reset.

[0045] In the second embodiment, the winding roller 11 is rotated after the insert plate is pulled out, so as to avoid the insert plate affecting the cloth winding around the winding core A.

[0046] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
