Description

Technical Field

[0001] The invention relates to the technical field of winding equipment, and in particular to a winding equipment used for fabric weaving. Background Art

[0002] In the production and processing of textiles, a winding device is generally used to wind up the textiles. Through the cooperation between different winding rollers, the textiles are neatly collected on the winding device. By using different winding rollers, different textiles are wound up, thereby completing the production work.

[0003] A Chinese patent with authorization announcement number CN116101830B discloses a textile fabric winding device, which includes a frame, a first spreading device and a second spreading device are arranged in the frame, a fabric detection device is arranged on the first spreading device, the fabric detection device can detect the wrinkle condition of the fabric on the first spreading device, the first spreading device includes a first auger and a first shell, the first auger can flatten the fabric, the second spreading device includes a second auger and a second auger shell, the second auger can flatten the fabric again, and a sliding plate is arranged on the second shell, the sliding plate can change the contact area between the second auger and the fabric, thereby changing the size of the traction force of the second auger to flatten the fabric from the middle to both ends, thereby realizing the change of the size of the traction force for stretching the wrinkles according to the wrinkle condition of the fabric, being able to flatten the fabric more accurately, and improving the winding quality of the textile fabric winding device.

[0004] The Chinese patent with the authorization announcement number CN116177280B discloses a textile fabric processing and winding device, including a processing base. In the process of textile fabric winding, the drum is pressed against the wound textile fabric, and the drum rotates with the rotation of the winding core. During the rotation of the drum, the dust and impurities on the fabric are sucked into the storage cylinder through the suction pipe in the storage cylinder, thereby avoiding the problem that the surface of the wound and stored fabric is dirty. At the same time, the drum presses the fabric against the winding core, making the fabric winding more compact, achieving the effect of one machine with two uses. After the fabric winding is completed, the wound textile fabric is removed by two arc-shaped clamping plates, thereby avoiding the heavy fabric roll after winding, which is time-consuming and laborious to remove manually. In the process of removing and moving, the winding core of the unwound fabric on the receiving plate is pulled upward by a rope for installation, thereby improving the replacement efficiency and the accuracy of the replacement and installation of the winding core, and improving the efficiency of fabric winding.

[0005] When changing the roll, the existing cloth winding equipment needs to first apply glue to the outer wall of the paper tube, and then press the cloth on the paper tube. As the winding roller rotates, the cloth is gradually wound around the paper tube. This method not only makes a part of the cloth bonded to the paper tube unusable, causing waste, but also the bonded part of the cloth will have wrinkles, resulting in uneven winding, affecting the winding quality. Summary of the invention

[0006] The present invention provides a winding device for cloth weaving, aiming to solve the technical problem that the existing cloth winding device in the related art needs to first apply glue to the outer wall of the paper tube when changing the roll, and then press the cloth on the paper tube, and gradually wind the cloth on the paper tube as the winding roller rotates. This method not only makes a part of the cloth bonded to the paper tube unusable, causing waste, but also the bonded part of the cloth will have wrinkles, resulting in uneven winding, affecting the winding quality.

[0007] A winding device for fabric weaving of the present invention comprises: a machine base and a turning frame, wherein two horizontally arranged winding rollers are rotatably matched on the turning frame, and two vertically arranged pressure rollers are fixedly installed, and cutting knives are slidably matched on the pressure rollers along their axial directions; it also comprises a supporting unit, a pushing unit and a pressing unit; the supporting unit comprises a fixed frame rotating on the machine base, two mounting seats separately arranged on the fixed frame, and an arc-shaped mounting groove opened on the mounting seat, and the fixed frame can drive the mounting seat to abut against the winding roller in a non-winding state; the pushing unit comprises an arc-shaped first rotating frame rotating on the mounting groove, a first guide roller fixed to the first rotating frame, and a plurality of pushing plates arranged at intervals along the axial direction of the first guide roller and sliding along the radial direction thereof.

When contracted, the two rotating frames are located in the mounting groove; when opened, the two rotating frames can be placed on the outside of the winding roller in the non-winding state, the pushing plate faces the angle between the second guide roller and the winding roller in the non-winding state, and the first guide roller is located on the winding side of the cloth.

[0008] Beneficial effect: When the paper roll is close to being wound up, the cylinder drives the mounting seat to be placed at the bottom of the second winding roller (non-winding state). At this time, the first guide roller and the second guide roller are respectively placed on both sides of the second winding roller, which will push upward the cloth passing through the lower surface of the second winding roller. The first rotating frame and the second rotating frame can move outward at the same time until the first guide roller and the second guide roller are located near the top of the second winding roller. There is a gap between the first guide roller and the second winding roller, but the second guide roller is in contact with the second winding roller. When the cutting knife cuts the cloth, the pushing plate slides out of the loading slot, and the pushing plate is directed toward the angle formed between the second guide roller and the second winding roller. At the same time, all the pressing plates extend to the outside of the second guide roller at the same time. The pressing plates are made of rubber, so they have friction. As the second guide roller rotates, the cloth can be continuously pushed toward the angle formed between the second guide roller and the second winding roller through the pressing plate until it passes between the second guide roller and the second winding roller. At the same time, as the second winding roller rotates, the part cut off between the pressing roller and the second winding roller can be wound around the paper tube on the second winding roller.

At the same time, as the second winding roller rotates, the cut-off part between the pressing roller and the second winding roller can be wound around the paper roll on the second winding roller, and finally the cut-off end of the cloth is fixed to the second winding roller, and there is no need to apply glue to the paper roll, which effectively avoids the waste of cloth. At the same time, there is no need to stop the machine for gluing, which improves the work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] When changing the roll of the existing cloth winding equipment, it is necessary to first apply glue to the outer wall of the paper tube, and then press the cloth on the paper tube. As the winding roller rotates, the cloth is gradually wound on the paper tube. This method not only makes a part of the cloth bonded to the paper tube unusable, causing waste, but also the bonded part of the cloth will have wrinkles, resulting in uneven winding, affecting the winding quality. Therefore, the following technical solution is proposed to solve this problem.

[0035] like Figures 1 to 10 As shown, a specific embodiment of a winding device for fabric weaving of the present invention includes a roll changing module and a material pushing module.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, the roll changing module includes a machine base 10, a turning frame 11, a driving shaft 12, a first winding roller 13, a second winding roller 14, a pressing roller 15, a cutting blade 16 and a driving unit.

[0037] A turning frame 11 is rotatably mounted on the machine base 10, and a driving shaft 12 is fixedly mounted on the turning frame 11. The driving shaft 12 is horizontally arranged, and both ends of the driving shaft 12 pass through the turning frame 11, and both ends of the driving shaft 12 are rotatably matched with the machine base 10. A motor connected to the driving shaft 12 is mounted on the machine base 10, so that the motor can drive the driving shaft 12 to rotate, and the driving shaft 12 can drive the turning frame 11 to turn.

[0038] The turning frame 11 is composed of two horizontally spaced plates, which are fixedly mounted on the driving shaft 12, and each plate has a cross-shaped structure.

[0039] A first winding roller 13 and a second winding roller 14 are rotatably mounted inside the turning frame 11. The first winding roller 13 and the second winding roller 14 are rotatably mounted on the horizontal plane of the turning frame 11 near both ends. The first winding roller 13 and the second winding roller 14 are both sleeved with paper tubes for winding up the fabric. At the same time, the outer side walls of the first winding roller 13 and the second winding roller 14 are covered with anti-slip rubber protrusions, so that when the paper tube is sleeved on the first winding roller 13 and the second winding roller 14, it can drive the paper tube to rotate, thereby avoiding slipping when winding up the fabric.

[0040] A pressure roller 15 is also fixedly installed inside the turning frame 11 . Two pressure rollers 15 are horizontally arranged, and the two pressure rollers 15 are respectively fixedly installed on the vertical surface of the turning frame 11 near the two ends.

[0041] A cutting knife 16 is slidably mounted on the pressure roller 15. The blade of the cutting knife 16 on the upper pressure roller 15 extends upward, and the blade of the cutting knife 16 on the lower pressure roller 15 extends downward, and the cutting knife 16 can slide along the axial direction of the pressure roller 15. A driving mechanism (not shown in the figure) for driving the cutting knife 16 to slide is mounted on the pressure roller 15. The driving mechanism can be an electric telescopic rod or a lead screw structure. When the cutting knife 16 slides along the pressure roller 15, it can cut the cloth passing through the pressure roller 15.

[0042] like Figure 3 As shown, the driving unit is used to drive the first winding roller 13 and the second winding roller 14 to rotate, and includes a housing 20 , a clutch 21 , a rotating drum 22 , a driven wheel 23 and a driving wheel 24 .

[0043] The housing 20 is fixedly mounted on the outside of the turning frame 11, and the driving shaft 12 passes through the housing 20. Clutches 21 are fixedly mounted on both ends of the housing 20. The two clutches 21 are respectively connected to the first winding roller 13 and the second winding roller 14 in rotation, so that the rotation of the first winding roller 13 and the second winding roller 14 can be controlled respectively. A rotating drum 22 is rotatably mounted on the outside of the driving shaft 12, and a driven wheel 23 is fixedly mounted on the rotating drum 22. A driving wheel 24 driven by a motor is mounted on the machine base 10, and the driving wheel 24 and the driven wheel 23 are connected by a transmission belt, so that the driving wheel 24 can drive the rotating drum 22 to rotate through the driven wheel 23. At the same time, the rotating drum 22 is respectively matched with the two clutches 21 in transmission. When the rotating drum 22 rotates, the rotation of the first winding roller 13 and the second winding roller 14 can be controlled respectively through the two clutches 21. That is to say, the rotating drum 22 can keep rotating at all times, and the two clutches 21 can respectively control the connection with the first winding roller 13 and the second winding roller 14, so as to realize the independent rotation of the first winding roller 13 and the second winding roller 14. When the first winding roller 13 needs to rotate, the clutch 21 can make the rotating drum 22 drive the first winding roller 13 to rotate. Similarly, when the second winding roller 14 needs to rotate, the clutch 21 can make the rotating drum 22 drive the second winding roller 14 to rotate.

[0044] It is particularly emphasized that the driving of the first winding roller 13 and the second winding roller 14 belongs to the prior art, and the specific structure is not described in detail here.

[0045] like Figure 2 When winding the cloth, the first winding roller 13 first serves as a rotating roller for winding the cloth, and the cloth produced by the production equipment passes through the lower surface of the pressure roller 15 located below and the lower surface of the second winding roller 14 in sequence, and finally the end of the cloth is wound around the paper tube on the first winding roller 13 for winding. When the paper tube on the first winding roller 13 is wound, the cutting knife 16 located below the pressure roller 15 cuts the cloth, and then fixes the end of the cloth on the paper tube on the second winding roller 14 through the pushing module, and then the turning frame 11 rotates 180 degrees clockwise. At this time, the second winding roller 14 carries the cloth and swaps its position with the first winding roller 13, and the positions of the upper and lower pressure rollers 15 are also swapped. This state is the state when the first winding roller 13 is wound, and this cycle is used to realize the alternating winding of the cloth by the first winding roller 13 and the second winding roller 14.

[0046] The pusher module is used to press the cloth onto the winding roller. As the winding roller rotates, the end of the cloth can be rolled in, thereby eliminating the need to glue the paper tube and avoiding waste of cloth.

[0047] The pushing module includes a supporting unit, a pushing unit and a pressing unit.

[0048] like Figures 1 to 5As shown, the supporting unit includes a fixing frame 30 , a rotating seat 31 , a cylinder 32 , a mounting seat 33 , a mounting groove 34 and a driving wheel 35 .

[0049] The fixing frame 30 is rotatably mounted inside the base 10, and one fixing frame 30 is disposed on each of the two opposite side walls inside the base 10, and the two fixing frames 30 are disposed opposite to each other. In this embodiment, the fixing frame 30 is disposed obliquely, and one end close to the bottom of the base 10 is rotatably matched with it.

[0050] A swivel seat 31 is rotatably mounted near the middle position of the fixed frame 30, and a cylinder 32 is rotatably mounted on the machine base 10. The bottom of the cylinder 32 is rotatably matched with the machine base 10, and the telescopic part of the cylinder 32 is also rotatably matched with the swivel seat 31, so that when the cylinder 32 is extended or retracted, the fixed frame 30 can be pushed to rotate through the swivel seat 31.

[0051] In this embodiment, the two fixing frames 30 on both sides are provided with cylinders 32 for driving them to rotate. In other modified embodiments, the fixing frames 30 on both sides can be fixedly connected by fixing rods, so that the two fixing frames 30 can be pushed to rotate synchronously by one cylinder 32.

[0052] The upper ends of the fixing frames 30 on both sides are fixed with mounting seats 33, and the mounting seats 33 are provided with arc-shaped mounting grooves 34. In this embodiment, the mounting grooves 34 are semicircular ring structures, and both ends of the mounting grooves 34 are vertically upward opening structures.

[0053] The mounting groove 34 is located at the center of the bottom and a driving wheel 35 is rotatably mounted thereon. In this embodiment, the driving wheel 35 is a gear, and the driving wheel 35 is driven by a motor (not shown in the figure).

[0054] It is particularly emphasized that as the cylinder 32 drives the fixed frame 30 to rotate, when the mounting seat 33 rotates upward to a horizontal state, the arc-shaped portion on the mounting seat 33 just abuts against the winding roller (in a non-winding state), and the mounting groove 34 on the mounting seat 33 just happens to be at the bottom of the winding roller in the non-winding state.

[0055] like Figure 4 , Figure 5 and Figure 6 As shown, the pushing unit includes a first rotating frame 40 , a first guide roller 41 , a mounting section 42 , a loading slot 43 , a pushing plate 44 , a pushing roller 45 , a driving rod 46 and a step portion 47 .

[0056] The first rotating frame 40 is slidably matched in the mounting grooves 34 on the two mounting seats 33. The first rotating frame 40 is a semicircular ring structure, and the first rotating frame 40 is provided with teeth. When the first rotating frame 40 is installed in the mounting groove 34, it is meshed with the driving wheel 35. It is particularly emphasized that the first rotating frame 40 is coaxially arranged with the mounting groove 34, so that when the motor drives the driving wheel 35 to rotate, the first rotating frame 40 can be driven to rotate, and when the first rotating frame 40 rotates, it can rotate around its own circumference.

[0057] Since the first rotating frame 40 is a semicircular ring structure with an angle of 180 degrees, when the first rotating frame 40 rotates to the maximum stroke, the planes on which the two ends of the first rotating frame 40 are located are in a vertical state, that is, half of the first rotating frame 40 is in the mounting groove 34, and the other half is located outside the mounting groove 34, and the driving wheel 35 is engaged with the end of the first rotating frame 40.

[0058] First guide rollers 41 are fixedly installed on the inner sides of the two first rotating frames 40 . The front and rear ends of the first guide rollers 41 are respectively located at the moving ends of the first rotating frames 40 , and the first guide rollers 41 are arranged horizontally.

[0059] The first guide roller 41 has a plurality of mounting sections 42, which are arranged at intervals along the axial direction of the first guide roller 41. Two loading grooves 43 are provided on each mounting section 42 along the axial direction of the first guide roller 41, and the loading grooves 43 are inclined downward. A push plate 44 is slidably connected to each loading groove 43 through a spring, and the push plate 44 can slide along the radial direction of the first guide roller 41. One side of the push plate 44 located in the axial direction of the first guide roller 41 is an inclined surface, and a push roller 45 is rotatably installed at the moving end of the push plate 44.

[0060] A driving rod 46 is slidably installed inside the first guide roller 41 along its axial direction. A telescopic rod (not shown in the figure) is provided at the end of the driving rod 46 to push it to move. The telescopic rod can push the driving rod 46 to slide inside the first guide roller 41.

[0061] The driving rod 46 is provided with a plurality of step portions 47 at intervals along the axial direction thereof, and each step portion 47 corresponds to a push plate 44 , and the step portion 47 corresponds to the inclined surface on the push plate 44 .

[0062] When the telescopic rod pushes the driving rod 46 to move, the step portion 47 on the driving rod 46 contacts the inclined surface on the pushing plate 44 , and can drive the pushing plate 44 to slide out of the loading slot 43 .

[0063] like Figure 5 and Figure 7 As shown, the pressing unit includes a second rotating frame 50 , a second guide roller 51 , a friction segment 52 , a pressing plate 53 , a protrusion 54 , a sliding rod 55 , a pushing block 56 and a pushing rod 57 .

[0064] The second rotating frame 50 is slidably matched in the mounting grooves 34 on the two mounting seats 33. The second rotating frame 50 is a semicircular ring structure, and the second rotating frame 50 is provided with teeth. When the second rotating frame 50 is installed in the mounting groove 34, it meshes with the driving wheel 35. The second rotating frame 50 is coaxially arranged with the mounting groove 34, so that when the motor drives the driving wheel 35 to rotate, the second rotating frame 50 can be driven to rotate, and when the second rotating frame 50 rotates, it can rotate around its own circumference.

[0065] Since the second rotating frame 50 is a semicircular ring structure with an angle of 180 degrees, when the second rotating frame 50 rotates to the maximum stroke, the planes on which the two ends of the second rotating frame 50 are located are in a vertical state, that is, half of the second rotating frame 50 is in the installation groove 34, and the other half is located outside the installation groove 34, and the driving wheel 35 is engaged with the end of the second rotating frame 50.

[0066] It is particularly emphasized that the second rotating frame 50 and the first rotating frame 40 are respectively located on both sides of the driving wheel 35, so that when the driving wheel 35 drives the second rotating frame 50 and the first rotating frame 40 to move, the second rotating frame 50 and the first rotating frame 40 have the same movement state, that is, they both move into the installation groove 34 or move toward the outside of the installation groove 34.

[0067] Second guide rollers 51 are rotatably mounted inside the two second rotating frames 50 . The front and rear ends of the second guide rollers 51 are respectively located at the moving ends of the second rotating frames 50 , and the second guide rollers 51 are arranged horizontally.

[0068] The second guide roller 51 has a plurality of friction segments 52, which are arranged in sequence and spaced apart along the axial direction of the second guide roller 51. The friction segments 52 on the second guide roller 51 correspond to the mounting segments 42 on the first guide roller 41 one by one.

[0069] A plurality of pressing plates 53 are slidably mounted on each friction section 52 along its circumferential direction. In this embodiment, the pressing plates 53 are made of rubber, and four pressing plates 53 are provided on each friction section 52. A spring is connected between the pressing plate 53 and the friction section 52 to ensure the resetting of the pressing plate 53, and the pressing plate 53 can slide along the radial direction of the friction section 52. A protrusion 54 is fixedly provided at the bottom of the pressing plate 53, and the protrusion 54 has an inclined surface. It is particularly noted that each pressing plate 53 faces the middle position of the corresponding two push plates 44.

[0070] A sliding rod 55 is slidably mounted inside the second guide roller 51. The sliding rod 55 is coaxially arranged with the second guide roller 51 and can slide along the axial direction of the second guide roller 51. A push rod 57 is fixedly mounted at the end of the sliding rod 55. The push rod 57 can drive the sliding rod 55 to slide along the axial direction of the second guide roller 51.

[0071] A plurality of push blocks 56 are arranged at intervals on the sliding rod 55 , and the push blocks 56 correspond to the friction sections 52 one by one. The push blocks 56 are in a frustum structure, and the push blocks 56 and the sliding rod 55 are arranged coaxially.

[0072] The protrusion 54 is located on the movement path of the pushing block 56. When the push rod 57 drives the sliding rod 55 to slide axially along the second guide roller 51, the pushing block 56 can push the pressing plate 53 through the protrusion 54, so that the pressing plate 53 slides radially along the second guide roller 51, and all the pressing plates 53 extend to the outside of the second guide roller 51 at the same time.

[0073] When the motor drives the driving wheel 35 to rotate, the first rotating frame 40 and the second rotating frame 50 can simultaneously move toward the outside of the mounting groove 34 until they rotate to the maximum stroke, and the first guide roller 41 and the second guide roller 51 abut against each other. At the same time, the first rotating frame 40 and the second rotating frame 50 form a circular ring structure (such as Figure 5 as shown).

[0074] like Figure 2 In this embodiment, the horizontal direction of the first winding roller 13 and the second winding roller 14 is defined as the left-right direction. When the first winding roller 13 is in the winding state, the first winding roller 13 is on the left side, and the second winding roller 14 is on the right side, and the second winding roller 14 only plays a conductive role, so the left side is the side where the cloth is wound, and the right side is the side where the produced cloth is delivered. Therefore, it is particularly emphasized that among the first guide roller 41 and the second guide roller 51, the first guide roller 41 is located on the left side, that is, the side where the cloth is wound, and the second guide roller 51 is located on the right side, that is, the side where the produced cloth is delivered.

[0075] When winding the cloth, the first winding roller 13 first serves as a rotating roller for winding the cloth, and the cloth produced by the production equipment passes through the lower surface of the pressure roller 15 located below and the lower surface of the second winding roller 14 in sequence, and finally the end of the cloth is wound around the paper tube on the first winding roller 13 for winding. When the paper tube on the first winding roller 13 is close to being wound, the cylinder 32 starts to push the fixed frame 30 to rotate through the rotating seat 31. As the cylinder 32 drives the fixed frame 30 to rotate, when the mounting seat 33 rotates upward to a horizontal state, the mounting groove 34 on the mounting seat 33 is just at the bottom of the second winding roller 14. At this time, the first guide roller 41 and the second guide roller 51 are respectively arranged on both sides of the second winding roller 14, which will push the cloth passing through the lower surface of the second winding roller 14 upward (such as Figure 8As shown), the motor then drives the driving wheel 35 to rotate, and the first rotating frame 40 and the second rotating frame 50 can simultaneously move toward the outside of the mounting groove 34. During this process, the first guide roller 41 and the second guide roller 51 will continue to push the cloth upward until the first guide roller 41 and the second guide roller 51 move to the maximum stroke. At this time, the first rotating frame 40 and the second rotating frame 50 are sleeved on the outside of the second winding roller 14, and the first guide roller 41 and the second guide roller 51 are located near the top of the second winding roller 14 (as shown in FIG. Fig. 9 and Fig.10 As shown in the figure, there is a gap between the first guide roller 41 and the second winding roller 14, but the second guide roller 51 is in contact with the second winding roller 14. After the cloth passes over the second guide roller 51 and turns, it turns from the bottom of the second winding roller 14, and finally winds out from the top of the first guide roller 41 and passes through the upper pressure roller 15 to be wound on the first winding roller 13.

[0076] Then the cutting knife 16 cuts the cloth. At the same time, the telescopic rod pushes the driving rod 46 to move, and the step portion 47 on the driving rod 46 contacts the inclined surface on the pushing plate 44, driving the pushing plate 44 to slide out of the loading slot 43, and the pushing plate 44 moves toward the angle formed by the second guide roller 51 and the second winding roller 14.

[0077] Since the second guide roller 51 is in contact with the second winding roller 14, the second winding roller 14 drives the second guide roller 51 to rotate. Fig. 9 and Fig.10 The arrow in the figure indicates the direction in which the second guide roller 51 drives the second winding roller 14 to rotate. While the cutting knife 16 cuts the cloth, the push rod 57 also drives the sliding rod 55 to move. The pushing block 56 can push the pressing plate 53 through the protrusion 54, so that the pressing plate 53 slides radially along the second guide roller 51. All the pressing plates 53 extend to the outside of the second guide roller 51 at the same time. The pressing plates 53 are made of rubber, so they have friction. As the second guide roller 51 rotates, the pressing plates 53 can continuously push the cloth to the angle formed between the second guide roller 51 and the second winding roller 14 until it passes between the second guide roller 51 and the second winding roller 14. At the same time, as the second winding roller 14 rotates, the cut portion between the pressing roller 15 and the second winding roller 14 can be wound around the paper tube on the second winding roller 14. Then the cylinder 32 drives the fixed frame 30 to descend and reset, and then the turning frame 11 rotates 180 degrees clockwise. At this time, the second winding roller 14 with the cloth is swapped with the first winding roller 13, and the positions of the upper and lower pressure rollers 15 are also swapped. This state is the state when the first winding roller 13 is winding. In this cycle, the first winding roller 13 and the second winding roller 14 can alternately wind up the cloth.
