Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to a core rolling machine and a fabric rolling machine. Background Technology

[0002] After being woven by weaving equipment, fabric needs to be wound onto a core using a fabric winding machine or similar equipment for storage and transport. Currently, the commonly used core is a smooth tubular structure. During winding, the fabric is first manually wound around the plastic core one or two times to create sufficient positioning friction, and then the winding roller drives the core to rotate and wind it up. Under the existing winding method, the fabric ends within the wound fabric are prone to compression and stacking, forming noticeable bulges. These bulges cause uneven stress on the subsequently wound fabric, resulting in defects in the initially wound section, making it a substandard product. For sensitive fabrics, the number of substandard sections caused by uneven stress is even greater. Therefore, this paper proposes an improved core design to solve the above problems. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a core winding machine and a fabric winding machine.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a core, comprising an inner core and an outer cylinder, wherein the outer wall of the inner core is provided with a positioning protrusion, the outer cylinder is provided with a positioning groove, the outer cylinder is detachably sleeved on the outside of the inner core, and the positioning protrusion is placed in the positioning groove to restrict the outer cylinder from rotating relative to the inner core, and a slit extending along the length direction is opened on the cylinder wall of the outer cylinder, the slit being used to clamp the fabric.

[0005] Furthermore, the outer cylinder is made of an elastic material, allowing the gap width to elastically deform under stress. The gap is located in the middle section of the outer cylinder's elongation direction, and a guide opening is provided at at least one end of the gap. A flared guide portion is provided between the end of the gap and the guide opening.

[0006] Furthermore, at least one positioning groove is provided at each end of the outer cylinder, the positioning groove is opened from the end of the outer cylinder toward the middle section, and the positioning protrusion includes a fixed protrusion and a detachable protrusion, the fixed protrusion and the detachable protrusion are respectively provided at both ends of the inner core.

[0007] Furthermore, the inner core has a fixed end and a detachable end at both ends, and the fixed protrusion is located at the end of the inner core where the detachable end is located. When the detachable end and the detachable protrusion are detached, the outer cylinder is fitted into the end of the inner core used to install the detachable end.

[0008] Furthermore, an embedded ring groove is provided on one end face of the detachable end, and a locking hole is provided on the outer wall of the detachable end, which penetrates into the embedded ring groove. A locking element is provided in the locking hole, and one end of the inner core is inserted into the embedded ring groove and locked and positioned by the locking element.

[0009] Furthermore, each end of the outer cylinder is provided with two positioning grooves, which are symmetrically arranged relative to the axis of the outer cylinder. One end of the inner core is provided with two fixed protrusions symmetrically arranged relative to the axis of the inner core, and the other end of the inner core is provided with two detachable protrusions symmetrically arranged relative to the axis of the inner core.

[0010] Furthermore, the inner core is made of metal, and the outer cylinder is made of plastic.

[0011] A fabric rolling machine using the aforementioned core includes a winding device and a fabric insertion device. The core is disposed on the winding device. The fabric insertion device includes a lateral movement mechanism, a telescopic mechanism, and an insert plate. The lateral movement mechanism is disposed parallel to one side of the winding device. The telescopic mechanism is mounted on the lateral movement mechanism. The insert plate is mounted on the telescopic mechanism. The telescopic mechanism is used to drive the insert plate to insert into the gap in the direction of the core. The lateral movement mechanism is used to drive the insert plate to move laterally along the length of the gap.

[0012] Furthermore, a limiter is provided at the lower end of one end of the winding device to position the core so that the seam of the core is aligned with the orientation of the insert plate.

[0013] Furthermore, it also includes a fabric cutting device and a fabric clamping device. The fabric cutting device is mounted on a transverse mechanism, which drives the fabric cutting device to move transversely to cut the fabric. The fabric clamping device is used to wrap the fabric around the core on the winding device.

[0014] As can be seen from the above description of this utility model, compared with the prior art, the roll core and fabric rolling machine provided by this utility model have the following advantages: When the roll core of this application is rolled up, the fabric is positioned by inserting it into the slit, and the fabric ends will not be squeezed and stacked. Therefore, the fabric has good flatness and uniform force when it is wound on the roll core, which greatly reduces the defect rate and has good adaptability to delicate and sensitive fabrics. The roll core of this application adopts a structure combining an inner core and an outer cylinder. The inner core has high structural strength and can be adapted to the winding process of the fabric rolling machine. The outer cylinder has low cost and can be used for fabric roll storage and transportation. After the fabric roll is wound by the fabric rolling machine, the inner core can be disassembled and recycled. The fabric roll is supported by the outer cylinder, and there is no need for secondary winding, which improves work efficiency. The slits opened on the outer cylinder can clamp and fix the ends of the fabric. With the fabric insertion device of the fabric rolling machine, a fully automatic roll changing process can be realized, which greatly reduces labor costs. Attached Figure Description

[0022] The present invention will be further described below through specific embodiments.

[0023] Reference Figures 1 to 5 As shown, a winding core includes an inner core 1 and an outer cylinder 2. The outer wall of the inner core 1 has a positioning protrusion, and the outer cylinder 2 has a positioning groove 21. The outer cylinder 2 is detachably fitted over the inner core 1, and the positioning protrusion is placed within the positioning groove 21 to prevent mutual rotation between the outer cylinder 2 and the inner core 1. Specifically, at least one positioning groove 21 is provided at each end of the outer cylinder 2, opening from the end of the outer cylinder 2 towards the middle. The positioning protrusion includes a fixed protrusion 11 and a detachable protrusion 12, respectively located at both ends of the inner core 1. In one specific embodiment, each end of the outer cylinder 2 has two positioning grooves 21, symmetrically arranged relative to the axis of the outer cylinder 2. One end of the inner core 1 has two fixed protrusions 11 symmetrically arranged relative to the axis of the inner core 1, and the other end of the inner core 1 has two detachable protrusions 12 symmetrically arranged relative to the axis of the inner core 1.

[0024] A slit 22 extending along the length direction is provided on the wall of the outer cylinder 2. The outer cylinder 2 is made of plastic and is elastic. The slit 22 is located in the middle section of the outer cylinder 2 in the length direction. At least one end of the slit 22 is provided with a guide opening 23. A flared guide portion 24 is provided between the end of the slit 22 and the guide opening 23. The slit 22 is used to clamp the fabric.

[0025] The inner core 1 has a fixed end 3 and a detachable end 4 at its two ends, respectively. A fixed protrusion 11 is located at the end of the inner core 1 where the fixed end 3 is located. When the detachable end 4 and the detachable protrusion 12 are detached, the outer cylinder 2 is fitted into the end of the inner core 1 used to install the detachable end 4. An embedded annular groove 41 is formed on one end face of the detachable end 4, and a locking hole 42 is formed on the outer wall of the detachable end 4, which penetrates the embedded annular groove 41. A locking element 43 is provided in the locking hole 42. One end of the inner core 1 is inserted into the embedded annular groove 41 and locked and positioned by the locking element 43. The inner core 1, the fixed end 3, and the detachable end 4 are made of metal.

[0026] refer to Figure 6 As shown, a fabric rolling machine includes a winding device 5, a fabric inserting device 6, a fabric cutting device 7, and a fabric clamping device 8. The fabric core is disposed on the winding device 5. The fabric inserting device 6 includes a transverse movement mechanism 61, a telescopic mechanism 62, and an insert plate 63. The transverse movement mechanism 61 is disposed parallel to one side of the winding device 5. The telescopic mechanism 62 is mounted on the transverse movement mechanism 61. The insert plate 63 is mounted on the telescopic mechanism 62. The telescopic mechanism 62 is used to drive the insert plate 63 to be inserted into the gap 22 in the direction of the fabric core. The transverse movement mechanism 61 is used to drive the insert plate 63 to move laterally along the length direction of the gap 22. A limit switch is provided below one end of the winding device 5. In this embodiment, the limit switch is an extreme limit switch 51. A limiting groove 44 is provided at one end of the core. Specifically, the limiting groove 44 is set on the detachable end 4. The winding device 5 drives the core to rotate until the extreme limit switch 51 corresponds to the limiting groove 44. The extreme limit switch 51 is inserted into the limiting groove 44 to position the core angle. At this time, the core's seam 22 and the insert plate 63 are facing opposite positions. The fabric cutting device 7 is installed on the transverse movement mechanism 61. The transverse movement mechanism 61 drives the fabric cutting device 7 to move transversely to cut the fabric. The fabric clamping device 8 is used to wrap the fabric around the core on the winding device 5.

[0027] The following section provides a specific working process to further explain the principle of the core and winding machine of this application.

[0028] After the fabric winding machine completes winding a fabric roll, the fabric roll is pushed out from the winding device 5, and a new core is placed on the winding device 5. The lateral movement mechanism 61 drives the fabric cutting device 7 to move laterally to cut the fabric, and the fabric clamping device 8 wraps the cut fabric around the core on the winding device 5. The winding device 5 drives the core to rotate one revolution. When the core rotates to the state where the limit switch 51 corresponds to the limit groove 44, the limit switch 51 is inserted into the limit groove 44 to position the core angle. At this time, the core's seam 22 and the insert plate 63 are facing opposite positions. The fabric insertion device 6 operates, and the telescopic mechanism 62 drives the insertion plate 63 forward, causing the insertion plate 63 to press against the fabric and push it into the guide opening 23 in the direction of the roll core. Then, the lateral movement mechanism 61 moves, and the insertion plate 63 moves laterally along the seam 22, simultaneously pressing the fabric into the seam 22. The outer cylinder 2 is made of plastic and has a certain degree of elasticity; therefore, when the insertion plate 63 passes through the seam 22, it pushes the seam 22 open. After passing through, the seam 22 retracts and clamps and fixes the fabric. After the movement is completed, the telescopic mechanism 62 retracts and the lateral movement mechanism 61 resets. The limit switch 51 retracts, and the winding device 5 drives the roll core to rotate again. Since the fabric is already connected to the roll core, the rotation of the roll core will cause the fabric to wind around the roll core. Automatic roll changing is completed.

[0029] After the fabric roll is removed from the winding machine, the detachable end 4 and detachable protrusion 12 are removed, and the inner core 1 can be pulled out from the other end. At this time, the fabric roll is only supported by the outer cylinder 2 and can be directly stored and transported. After removal, the inner core 1 can be reinstalled with a new outer cylinder 2 to form a new roll core. This design eliminates the need for secondary winding, improving work efficiency.

[0030] Example 2 differs from Example 1 in that it uses a limiter. In Example 2, the limiter is a sensor, with a sensing point at one end of the core. Specifically, the sensing point is located on the detachable end 4. The winding device 5 drives the core to rotate until it stops when the sensor and the sensing point correspond. At this time, the slot 22 of the core and the insertion plate 63 are facing each other.

[0031] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be considered as an infringement of the protection scope of the present utility model.
