DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the utility model more clear, the technical scheme in the utility model will be clearly and completely described below in combination with the drawings.

[0021] Referring to Figure 2 , Figure 3 A cutting and tearing rewinding mechanism of a cord fabric comprises a first unwinding roller 101, an old release film winding roller 201 is arranged on the left side of the first unwinding roller 101, and a guide roller 103 is arranged on the right side of the first unwinding roller 101, the guide roller 103 corresponds to the feeding roller 301 of the slitting and rewinding device, the feeding roller 301 is arranged on the side of the cutting and tearing mechanism 3; the cutting and tearing mechanism 3 comprises the upper pressing roller 302 and the lower pressing roller 303 which are arranged in a vertical mode, the upper rewinding and film coating mechanism 4 is arranged on the right upper side of the cutting and tearing mechanism 3, and the lower rewinding and film coating mechanism 5 is arranged on the right lower side of the cutting and tearing mechanism 3.

[0022] The cutting mechanism 310 of the existing slitting and rewinding machine is replaced by the cutting and tearing mechanism 3, and the slitting cutter on the cutting roller in the cutting mechanism is removed, so that the warp of the cord fabric is prevented from being broken during cutting and tearing, thereby preventing the cord fabric from being damaged. Meanwhile, the upper pressing roller 302 and the lower pressing roller 303 press the cord fabric, so that the cord fabric is uniformly stressed in the width direction during cutting and tearing, and the cutting and tearing is neat.

[0023] According to the structural characteristics of the cord fabric, the cord fabric which is cut out of the cutting and tearing mechanism 3 is manually torn into several openings with a specified size, and the cord fabric strips which are manually torn are wound on the upper rewinding and film coating mechanism 4 and the lower rewinding and film coating mechanism 5 at intervals, and the rewinding force of the upper rewinding and film coating mechanism 4 and the lower rewinding and film coating mechanism 5 is used to cut and tear the cord fabric. Specifically, after the torn cord fabric strip is attached to the new release film 300 which is unwound from the upper unwinding roller 402 through the upper guide roller set 401, the cord fabric strip is wound on the upper rewinding and film coating roller 403; similarly, after the cord fabric strip which is wound on the upper rewinding and film coating mechanism at intervals is attached to the new release film 300 which is unwound from the lower unwinding roller 502 through the lower guide roller set 501, the cord fabric strip is wound on the lower rewinding and film coating roller 503.

[0024] Referring to Figure 3The first unwinding roller 101 and the guide roller 103 are provided with a first tension sensor 102, which is any one of an arm beam sensor and a through shaft tension sensor. Since the force for tearing the cord fabric is increased on the rewinding and film covering roller in the rewinding and film covering mechanism, the unwinding speed of the slitting and rewinding machine and the rewinding speed of the rewinding and film covering roller in the background technology are not matched, which can cause the cord fabric to relax, accumulate, or have excessive tension. Therefore, the arm beam sensor is arranged between the first unwinding roller 101 and the guide roller 103, so that the cutting and film covering of the cord fabric are more regular.

[0025] A meter 6 is arranged above the left side of the guide roller 103, which is used to measure the length of the cord fabric.

[0026] The unwinding speed and the rewinding speed of the old isolation film are not matched, which can cause the old isolation film to relax and accumulate on the rack, and cause the inside to be tight and the outside to be loose or the outside to be tight and the inside to be loose during rewinding. Sometimes, when the rewinding roller is wound to a certain diameter, deviation or skew can occur, which causes the cord fabric manufacturer to be unable to directly recycle the old isolation film. Therefore, a second tension sensor 202 is arranged between the first unwinding roller 101 and the old isolation film rewinding roller 201, and the rotating speeds of the unwinding roller and the rewinding roller are adjusted, so that the old isolation film is more compact and regular; the second tension sensor is any one of an arm beam sensor and a through shaft tension sensor.

[0027] The first unwinding roller 101 is connected to a drive motor one through a speed reducer, the old isolation film rewinding roller 201 is connected to a drive motor two through a speed reducer, the upper rewinding and film covering roller 403 of the upper rewinding and film covering mechanism 4 and the lower rewinding and film covering roller 503 of the lower rewinding and film covering mechanism 5 are connected to a drive motor three through a chain, and the first tension sensor 102, the second tension sensor 202, the drive motor one, the drive motor two, and the drive motor three are respectively connected to a PLC controller.

[0028] The first unwinding roller 101 is provided with bearing seats at both ends, and one of the bearing seats is provided with a rotating gear outside, which is in meshing connection with the main shaft gear of the speed reducer of the first unwinding roller 101. The old isolation film winding roller 201 is provided with bearing seats at both ends, and one of the bearing seats is provided with a rotating gear outside, which is in meshing connection with the main shaft gear of the speed reducer of the old isolation film winding roller 201. The first unwinding roller 101 and the old isolation film winding roller 201 are both air inflation rollers (prior art). The first unwinding roller 101 is provided with a locking handle at both ends of the shaft, and when the first unwinding roller 101 needs to be unwound, the locking handle is used to open the first unwinding roller mounting shaft seat, and then the first unwinding roller 101 is inserted into the winding drum of the strip material and placed on the first unwinding roller mounting shaft seat. Then the locking handle is used to close the first unwinding roller mounting shaft seat, and the rotating gear on the first unwinding roller 101 is in meshing connection with the main shaft gear of the speed reducer, so that the first unwinding roller 101 can be quickly disassembled and assembled, and the winding drum of the strip material can be quickly unwound or wound. Similarly, the old isolation film winding roller 201 is provided with a locking handle at both ends of the shaft, so that the old isolation film winding roller 201 can be quickly disassembled and assembled, and the wound old isolation film can be easily removed.

[0029] The cord fabric is made of strong strands as warp and thin single yarns as weft. The warp, also called cord, bears the load, and the weft fixes the position of the warp. When a certain force is applied, the cord fabric can be separated along the warp, and the weft is directly broken, while the warp is not affected. Due to the structure of the cord fabric, only an opening needs to be torn in the cord fabric during cutting, and the remaining part will be torn along the opening. In actual work, the end of the cord fabric is torn according to the set width, and the torn cord fabric is introduced into the upper and lower rewinding and laminating mechanisms respectively and at intervals. During rewinding and laminating, the cord fabric is separated along the initial tear line at the upper and lower pressure rollers 302 and 303 under the pulling of the rewinding and laminating rollers, and the warp is not affected. Therefore, no dividing cutter is used to divide the cord fabric during cutting.

[0030] The second unwinding roller 402 and the rewinding and laminating roller 403 are both air inflation rollers.

[0031] The material wound on the winding drum in the embodiment is the material after the cord fabric and the old isolation film are pasted and wound on the winding drum.

Specifically, the torn cord fabric strips are attached to the new release film 300 released by the upper guide roller group 401 and the upper unwinding roller 402, and are wound on the upper rewinding and film coating roller 403 inserted into the empty reel; similarly, the cord fabric strips wound at intervals between the upper rewinding and film coating mechanism are attached to the new release film 300 released by the lower guide roller group 501 and the lower unwinding roller 502, and are wound on the lower rewinding and film coating roller 503 inserted into the empty reel. And the old release film passes through the second tension sensor 202 and is wound on the old release film winding roller 201 inserted into the empty reel.

[0034] The first tension sensor measures the tension of the cord fabric, and transmits the tension signal to the PLC controller 7, and adjusts the rotating speed of the first unwinding roller 101 and the upper and lower rewinding and film coating rollers through the PLC controller 7 and the driving motor one and the driving motor three, so that the unwinding speed and the rewinding speed of the rewinding and film coating rollers are matched, the tension of the cord fabric is balanced, the phenomenon of cord fabric relaxation and accumulation is avoided, the cutting and film coating of the cord fabric are more regular, and the cutting and film coating of the cord fabric are more regular.

[0035] The second tension sensor detects the tension of the old release film, and transmits the tension signal to the PLC controller 7, and adjusts the rotating speed of the old release film winding roller 201 through the driving motor two, so that the tension of the old release film is balanced through the PLC controller 7, the phenomenon of old release film relaxation and accumulation is avoided, the situation of inside tight and outside loose or outside tight and inside loose is avoided during winding, the old release film winding is more compact and regular, and a meter counter is arranged above the left side of the guide roller 103 to measure the length of the cord fabric.

[0036] The meter counter is also electrically connected with the PLC controller 7, and controls the rotating speed of the driving motors 1, 2 and 3, so that the rotating speeds of the three are matched.

[0037] The reducer, the air expansion roller and the meter counter in the utility model are conventional components purchased on the market, so the cooperation of the reducer and the driving motor is not described in detail; the working process of the air expansion roller and the meter counter is not described in detail.

[0038] The preferred embodiments of the utility model are described above, and it should be noted that, for those skilled in the art, without departing from the overall concept of the utility model, some changes and improvements can be made, and these should also be considered as the protection range of the utility model.
