Description

Technical Field

[0001] This invention relates to the field of paper-insulated cotton roll packaging machinery technology, and in particular to a binding and wrapping film device for paper-insulated cotton rolls and its usage method. Background Technology

[0002] Paper-insulated cotton rolls are flexible, roll-shaped functional composite materials made with inorganic fibers (such as glass fiber and rock wool) as the core layer and paper or non-woven fabric as the reinforcing interlayer, formed through physical composite processes (needle punching, hot pressing, or adhesive bonding). They combine the thermal insulation, sound absorption, noise reduction, and fire-retardant properties of inorganic fibers with the mechanical reinforcement, tear resistance, and morphological stability of the paper interlayer, making them a typical flexible thermal insulation material in industrial and construction fields.

[0003] After the paper-insulated cotton rolls are produced, they need to be physically packaged based on the systemic requirements of material properties, logistics safety, storage efficiency and quality protection. This requires the use of paper-insulated cotton roll binding and wrapping film equipment.

[0004] Currently, most existing paper-insulated cotton roll wrapping and binding film equipment uses a traditional linear winding structure. This structure has the following problems in practical use: 1. In linear winding, the roll moves horizontally in a straight line, and the bottom support mainly relies on single-point support rollers. The spacing between traditional rollers is typically 400-500 mm. Furthermore, the overall conveying span is large, and when encountering large-diameter rolls, the paper-insulated cotton roll is prone to sagging, deformation, and interlayer misalignment at the suspended ends between rollers, resulting in poor adaptability and insufficient support and stability. This can easily lead to a funnel-shaped opening during subsequent winding. 2. In linear winding, the contact angle between the film and the roll surface fluctuates significantly during large-span conveying, easily causing air bubbles and wrinkles. 3. Linear winding requires allowance for "roll conveying, winding, and unloading." The linear space is generally no less than eight meters, which results in a large overall footprint and low space utilization. Therefore, this application provides a binding and winding film device for paper-clamped cotton rolls and its usage method to meet the requirements. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a binding and winding film device for paper-insulated cotton rolls and its usage method to solve the problems that the existing winding and transportation structure of paper-insulated cotton rolls is mostly linear winding, which has poor adaptability and insufficient support and stability for large-size rolls. At the same time, the adhesion between the roll and the film is poor, which easily forms air bubbles and wrinkles. In addition, the equipment occupies a large area and has low space utilization.

[0015] A method for using a binding and wrapping device for paper-insulated cotton rolls includes the following steps: Step 1: Before starting work, according to the production specifications of the paper-insulated cotton roll felt, if the specifications are larger than 800 mm, the servo motor in the trajectory adjustment module is started by controlling the external operating table. The rotation of the servo motor drives the lead screw to rotate synchronously, thereby causing the adjustment block and the docking flange to expand and move along the groove inside the support rod in the semi-circular frame. This expands the trajectory radius of the multiple arc-shaped conveyor rollers and increases the curvature of the outer roll wrapped around the multiple conveyor rollers. The multiple conveyor rollers provide stable multi-point support below the outer roll. If the specifications are smaller than 800 mm, the above operation is reversed to reduce the curvature of the outer roll supported by the multiple conveyor rollers. Step 2: After the trajectory adjustment module is adjusted, the tensioning module starts working. The tensioning motor in the tensioning module drives the tensioning screw to rotate, allowing the displacement block to move back and forth along the longitudinal groove. The displacement block and the fixed block are reinforced together with screws, which can drive the positioning module to move synchronously along the displacement direction and angle of the displacement block. At the same time, since the positioning module is wrapped inside the outer roll, the outer roll can be tightened or loosened when the positioning module moves back and forth. In small-scale production, the positioning module will move forward to tighten the slack caused by the contraction of the trajectory adjustment module. In large-scale production, the positioning module will move backward to gradually release the tension caused by the expansion of the trajectory adjustment module, so that the outer roll always maintains a stable tension. Step 3: After the tensioning module and positioning module complete the tension adjustment of the external roll, the holding module starts to work. The holding motor drives the front drive shaft to rotate, thereby causing the lifting block to move up and down in the lifting groove. This causes the holding rollers installed on the outside of the lifting block to move synchronously, so that the holding rollers are pressed against the top of the external roll. This ensures that the external roll wrapped around the outer ends of multiple conveyor rollers, guide rollers, tension rollers and traction rollers can always maintain a suitable angle to convey the paper-insulated cotton roll. This ensures that the paper-insulated cotton roll and the overall movement trajectory tangent of the film material are consistent, allowing them to fit better together. This reduces the probability of the two sides forming a flared opening during subsequent winding, and also reduces the problem of air bubbles and wrinkles when the film material and the paper-insulated cotton roll are wrapped and wound. Step 4: After the paper-insulated cotton roll is fed into the winding machine, the roll structure inside the winding machine winds the paper-insulated cotton roll into a roll. The tape attached to the round rod at the front of the winding machine completes the binding and wrapping work. After binding and wrapping, it is discharged through the unloading structure at the rear of the winding machine. Step 5: Lay the pre-mounted module on both sides of the tensioning module using the set ground rails. Then, move the pre-mounted module along the ground rails, sliding it to the top of the tensioning module and aligning it with the front end of the conveyor base, leaving a suitable gap. Together with the external roll wrapped around the multiple conveyor rollers, guide rollers, tension rollers, and traction rollers, and in conjunction with the track adjustment module, it forms a complete arc-shaped winding conveyor structure. Compared to the traditional straight winding conveyor equipment that requires eight meters of space, the arc-shaped winding conveyor structure can reduce the total length of the equipment to within five meters, reducing the space occupancy rate. This is suitable for small and medium-sized building material factories with insufficient workshop width. Furthermore, the pre-mounted module is designed to be movable using the ground rails, making subsequent maintenance more convenient and faster. At the same time, the length and size of the pre-mounted module can be adjusted according to actual production needs, providing convenience for subsequent equipment layout. Step 6: The bottom film material can be placed on the inside for installation using the film-laying support, so that it can be laid out during subsequent production. The cutting module has a support platform on its inside that matches the conveying height of the front module. Once the paper-clamped cotton roll reaches the appropriate length, the cutting motor drives the cutting blade to move downwards to complete the cutting of the paper-clamped cotton roll.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, a servo motor drives a lead screw to rotate, thereby causing the adjusting block and the docking flange to expand and displace along the groove inside the support rod of the semi-circular frame. The docking flange and the two ends of the conveyor rollers are spliced ​​and assembled into an integrated structure, thereby adjusting the expansion or contraction of multiple conveyor rollers and causing the outer roll of the outer belt wrapping around the multiple conveyor rollers to expand or contract. Through the adjustable trajectory radius conveying structure and the multi-point support under the outer roll, the support stability and adaptability of conveying different specifications of paper-clamped cotton felt rolls are improved compared to traditional linear winding. Secondly, a tensioning motor drives a tensioning screw to rotate, allowing the displacement block to move back and forth along the longitudinal groove. The displacement block and the fixed block are connected by... The screws are tightened together, which allows the positioning module to move synchronously along the displacement direction and angle of the displacement block. At the same time, since the positioning module is wrapped inside the outer roll, the outer roll can be tightened or loosened when the positioning module moves back and forth. In small-scale production, the positioning module will move forward to tighten the slack of the outer roll caused by the contraction of the trajectory adjustment module. In large-scale production, the positioning module will move backward to gradually release the tension of the outer roll caused by the expansion of the trajectory adjustment module. This ensures that the outer roll maintains a stable tension, preventing it from being too loose and thus failing to adhere to the film, and also preventing it from being too tight and causing fluctuations that affect the adhesion between the film and the outer roll.

[0017] The pressure motor drives the front drive shaft to rotate, which in turn causes the lifting block to move up and down in the lifting groove. This causes the pressure rollers installed on the outside of the lifting block to move synchronously, allowing the pressure rollers to press against the top of the outer roll. This ensures that the outer roll, which is wrapped around the outer ends of multiple conveyor rollers, guide rollers, tension rollers, and traction rollers, can always maintain a suitable angle to transport the paper-insulated cotton roll. This ensures that the tangent of the paper-insulated cotton roll and the overall movement trajectory of the film material are consistent, allowing them to fit together better. This reduces the probability of flaring at both sides during subsequent winding and also reduces the problems of air bubbles and wrinkles that occur when the film material and the paper-insulated cotton roll are wrapped together during winding.

[0018] The front module is laid on both sides of the tensioning module via a set ground rail. Then, the front module is moved along the ground rail, sliding to a position above the tensioning module, fitting snugly against the front end of the conveyor base with appropriate spacing. Together with the external roll wrapped around multiple conveyor rollers, guide rollers, tension rollers, and traction rollers, and in conjunction with the trajectory adjustment module, it forms a complete arc-shaped winding conveyor structure. Compared to the traditional eight-meter footprint required for linear winding conveyors, the arc-shaped winding conveyor structure can reduce the total footprint to within five meters, lowering the equipment's space occupancy rate. This is suitable for small and medium-sized building material factories with insufficient workshop width. Furthermore, the ground rail design allows the front module to be movable, making maintenance easier and faster. Additionally, the length and size of the front module can be adjusted according to actual production needs, facilitating subsequent equipment layout. Attached Figure Description

[0028] like Figures 1 to 14As shown, an embodiment of the present invention provides a binding and winding film device for paper-clamped cotton rolls, including a conveyor base 1, a semi-circular frame 2 at the middle of the upper end of the conveyor base 1, a track adjustment module 3 on the inner side of the upper end of the semi-circular frame 2, a pressing module 4 on the front and rear sides of the upper end of the conveyor base 1, a tensioning module 5 below the front end of the conveyor base 1, ground rails 6 on the left and right sides of the front of the conveyor base 1, a front module 7 on the inner side of the upper end of the ground rail 6, a cutting module 8 above the front end of the front module 7, a film-laying support 9 below the cutting module 8, a winding machine 10 on the rear side of the conveyor base 1, fixing blocks 11 on the left and right sides inside the semi-circular frame 2, and a positioning module 12 on the inner side of the upper end of the tensioning module 5.

[0029] The conveyor base frame 1 and the semi-circular frame 2 are assembled and reinforced with six bolts on each side. The trajectory adjustment module 3 is embedded inside the semi-circular frame 2. The pressure modules 4 are symmetrically distributed, with four sets on each side. The four sets are located in the front and rear areas, and the distance between the two front and rear sets and the semi-circular frame 2 is equal. The tensioning modules 5 are symmetrically distributed in two sets, and the rear ends of the two sets of tensioning modules 5 are reinforced with bolts to the lower front end of the conveyor base frame 1. The ground rails 6 are symmetrically distributed in two sets, and the distribution distance between the two ground rails 6 is adapted to the overall width of the lower end of the front module 7. The upper left and right sides of the front module 7 are concave and convex, with four concave surfaces. The inner side of the concave surfaces can be welded and installed with the upper film support as needed. The front module 7 is embedded in the inner side of the upper end of the ground rails 6, and the two can slide together. The contact end between the front module 7 and the ground rail 6 can be limited and reinforced by a pin. The cutting module 8 and the front end of the front module 7 can be reinforced by a screw. The film-laying support 9 is independent, and its specific placement area can be moved according to the actual displacement area of ​​the front module 7. Since the bottom of the film-laying support 9 has a working slot for the insert plate carriage, it is easy to lift and move. The winding machine 10 is a known technology and is the tail end device for winding paper cotton rolls into rolls. Therefore, it will not be described in detail in this invention. The fixed pressure block 11 is reinforced with the semi-circular frame 2 by a tail bolt. The structure of the fixed pressure block 11 is the same as the structure formed by the lifting block 405, the pressure wheel 406 and the side plate 407 in the pressure module 4. A pressure roller is installed in front of the positioning module 12. The positioning module 12 and the displacement block 507 inside the tensioning module 5 are reinforced together by screws.

[0030] During operation, according to the production specifications of the paper-insulated cotton roll felt, the track adjustment module 3, controlled by the external control panel, begins to work. It expands and displaces along the groove inside the support rod 204 in the semi-circular frame 2, thereby enlarging or contracting the curvature of the outer roll wrapping multiple conveyor rollers 205. Simultaneously, it provides stable multi-point support below the outer roll. After the track adjustment module 3 completes its adjustment, the tensioning module 5 begins to work, driving the positioning module 12 to move back and forth. Since the positioning module 12 is wrapped inside the outer roll, its back-and-forth movement tightens or loosens the outer roll. Specifically, during small-scale production, the positioning module 12 moves forward to reduce the slack in the outer roll caused by the contraction of the track adjustment module 3. When encountering large-scale production, the positioning module 12 will move backward to gradually release the tension of the outer roll caused by the expansion of the trajectory adjustment module 3, so that the outer roll always maintains a stable tension. After the tensioning module 5 and the positioning module 12 complete the tension adjustment of the outer roll, the holding module 4 starts to work. In conjunction with the fixing block 11, the outer roll wrapped around the outer ends of multiple conveying rollers 205, guide rollers 102, tension rollers 124 and traction rollers 125 can always maintain a suitable angle to convey the paper-insulated cotton roll felt. This makes the tangent of the movement trajectory of the paper-insulated cotton roll felt and the film material consistent, so that the two can fit better. This reduces the probability of forming a flared mouth on both sides when rewinding, and also reduces the problem of air bubbles and wrinkles when the film material and the paper-insulated cotton roll felt are wrapped and rewound.

[0031] like Figures 1 to 14 As shown, in this embodiment, the conveyor base frame 1 includes a support frame 101, guide rollers 102, a conveyor motor 103, a conveyor wheel 104, and crossbars 105. Guide rollers 102 are symmetrically distributed on the front and rear sides of the upper end of the support frame 101. A conveyor motor 103 is located below the guide rollers 102. A conveyor wheel 104 is located on the right side of the outer end of the guide rollers 102. Crossbars 105 are symmetrically distributed on the front and rear sides inside the support frame 101. The semi-circular frame 2 includes a left clamping plate 201, a right clamping plate 202, an arc-shaped rod 203, a support rod 204, a conveyor roller 205, and a heat dissipation device. The machine 206 and the heat dissipation filter 207 are provided. A right plate 202 is provided on the right side of the left plate 201. Arc-shaped rods 203 are symmetrically provided on the upper ends of the left plate 201 and the right plate 202. A support rod 204 is provided on the inner side of the arc-shaped rods 203. A conveying roller 205 is provided above the middle of the middle of the left plate 201 and the right plate 202. A heat dissipation motor 206 is provided on the upper middle of the right end of the left plate 201 and the upper middle of the left end of the right plate 202. A heat dissipation filter 207 is provided on the middle of the left side of the outer end of the left plate 201 and the middle of the right side of the outer end of the right plate 202.

[0032] A guide seat is installed between the support frame 101 and the guide roller 102. The guide seats are symmetrically distributed on the left and right sides. The guide roller 102 is sleeved inside the symmetrically distributed guide seats and reinforced with bolts. The support frame 101 is also reinforced with bolts to the guide seats. The conveyor motor 103 is installed in the rear area of ​​the right end of the support frame 101, perpendicular to the installation angle of the upper guide roller 102. The drive end of the conveyor motor 103 passes through the interior of the support frame 101 and extends to the outside. A drive wheel is installed on the extended part. At the same time, a conveyor is also sleeved on the right side of the outer end of the guide roller 102. Wheel 104 is reinforced with screws. The conveyor wheel 104 and the drive wheel are connected by a drive belt. Crossbars 105 are symmetrically distributed on the inner side of the support frame 101. The contact ends of the support frame 101 and the crossbars 105 are reinforced by welding. The left and right clamping plates 201 and 202 are symmetrically distributed and are identical in size and shape. Both the left and right clamping plates 201 and 202 have a circular structure at the upper center, and the interior of the circular structure is hollow. The hollow interior of the circular structure is interconnected with the bottom inner side of the support rod 204. Two rods 203 are symmetrically distributed on the left and right sides. Each of the two arc-shaped rods 203 combines with the left and right retaining plates 201 and 202 respectively to form a structure with a rectangular bottom and a semi-circular top. The lower end of the support rod 204 is cylindrical and hollow. Simultaneously, the upper end of the support rod 204 has a through-type sliding groove. The support rods 204 are symmetrically installed on the inner sides of the two semi-circular structures, with six rods distributed on each side. The tops of the six support rods 204 are reinforced by welding to the inner surfaces of the two semi-circular structures, while the bottoms of the six support rods 204 are connected to the left retaining plate 202. The circular structure at the upper center of the left and right card plates 201 and 202 is reinforced by welding. The conveying roller 205 is installed in the middle area of ​​the support rods 204 that are symmetrically distributed on the left and right. The left and right ends of the conveying roller 205 are provided with docking plates. The docking plates are spliced ​​with the docking flanges 304 in the trajectory adjustment module 3 and reinforced by bolt assembly. There are two symmetrically distributed cooling motors 206 on the left and right. Both cooling motors 206 are fixed with bolts inside the circular structure at the upper center of the left and right card plates 201 and 202. The outer side of both circular structures is provided with a heat dissipation filter 207.

[0033] During operation, the traditional linear support roller structure is modified by the support frame 101 and guide roller 102 in conjunction with the left clamping plate 201, right clamping plate 202, arc-shaped rod 203, support rod 204, and conveyor roller 205. This results in a combined support roller structure with an arc-shaped support roller in the middle and straight support rollers on both sides. An external conveyor belt is then wrapped around the outside of the combined support roller structure to form a conveying structure. Compared to the traditional linear conveying structure, this modification shortens the overall length of the conveying structure, thereby reducing the equipment's footprint and improving space utilization. Simultaneously, the circular knots at the upper center of the left clamping plate 201 and right clamping plate 202, along with the cylindrical cavity on the inner side of the bottom of the support rod 204 and the through-type sliding slot at the upper end, allow the trajectory adjustment module 3 to be installed inside. This allows the combined support roller structure to expand and contract without increasing the overall equipment volume, thus changing its running trajectory.

[0034] like Figures 5 to 6 As shown, in this embodiment, the trajectory adjustment module 3 includes a servo motor 301, a lead screw 302, an adjustment block 303, and a docking flange 304. The front end of the servo motor 301 is provided with a lead screw 302, and the outer end of the lead screw 302 is threadedly connected to the adjustment block 303. The front end of the adjustment block 303 is provided with a docking flange 304.

[0035] The servo motor 301 and the lead screw 302 are connected in a sleeved installation structure, and the sleeved ends of the two are reinforced by a retaining pin. The adjusting block 303 is threadedly installed on the outer end of the lead screw 302. The mating flange 304 is fixed to the front end of the adjusting block 303 by welding. Furthermore, the servo motor 301, lead screw 302, adjusting block 303 and mating flange 304 are symmetrically distributed in two groups, each group containing six servo motors 301, six lead screws 302, six adjusting blocks 303 and six mating flanges 304.

[0036] During operation, the servo motor 301 starts working, driving the lead screw 302 to rotate synchronously. This causes the adjusting block 303 and the docking flange 304 to expand or contract along the groove inside the support rod 204 in the semi-circular frame 2. This adjusts the trajectory radius of the multiple arc-shaped conveyor rollers 205 assembled with the docking flange 304, expanding or contracting them. This provides multi-point support below the outer roll, improving the support stability and adaptability of conveying paper-insulated cotton rolls of different specifications compared to traditional linear winding.

[0037] like Figures 1 to 9As shown, in this embodiment, the pressing module 4 includes a pressing base 401, a lifting groove 402, a sealing plate 403, a pressing motor 404, a lifting block 405, a pressing wheel 406, and a side plate 407. The lifting groove 402 is provided on the inner side of the upper end of the pressing base 401. The sealing plate 403 is provided at the upper end of the pressing base 401. The pressing motor 404 is provided in the middle of the upper end of the sealing plate 403. The lifting block 405 is provided inside the lifting groove 402. The pressing wheel 406 is provided below the left end of the lifting block 405. The side plate 407 is provided on the left side of the pressing wheel 406.

[0038] The holding module 4 is installed symmetrically from left to right. The holding base 401 has a lifting groove 402 inside. The contact end between the lifting groove 402 and the inner outer wall of the holding base 401 has a longitudinal rectangular opening. The sealing plate 403 and the holding base 401 are reinforced by four bolts located at their four corners. The holding motor 404 is reinforced by screws in the middle of the upper end of the sealing plate 403. The drive end of the holding motor 404 passes through the interior of the sealing plate 403 and the lifting block 405 and extends to the lower outer side. The lifting block 405 consists of a rectangular structure and a side L-shaped structure. The outer diameter of the rectangular structure matches the inner diameter of the lifting groove 402, while the side L-shaped structure... The width of the lifting groove 402 and the contact end of the inner outer wall of the pressing base 401 are adapted to form a longitudinal rectangular opening width. The pressing wheel 406 and the side L-shaped structure in the lifting block 405 are connected by a plug rod. The front end of the plug rod passes through the interior of the side L-shaped structure in the lifting block 405 and the interior of the pressing wheel 406 in sequence and extends to the rear side of the side plate 407, and is limited by a screw. The side plate 407 is also reinforced with the side L-shaped structure in the lifting block 405 by a screw. There is a gap of a few centimeters between the lower end of the side plate 407 and the lower end of the pressing wheel 406 to prevent the side plate 407 from contacting the surface of the external winding tape when pressing the external winding tape later.

[0039] During operation, the pressure motor 404 starts working, which drives the lifting block 405, which is penetrated by the drive shaft, to move up and down in the lifting groove 402. This causes the pressure roller 406, which is installed on the outside of the lifting block 405, to move synchronously. The pressure roller 406 presses against the top of the outer roll, so that the outer roll wrapped around the outer ends of the multiple conveyor rollers 205, guide rollers 102, tension rollers 124 and traction rollers 125 can always maintain a suitable angle to convey the paper-insulated cotton roll. This ensures that the tangent of the movement trajectory of the paper-insulated cotton roll and the film material are consistent, allowing them to fit better together. This reduces the probability of the two sides forming a flared opening during subsequent winding, and also reduces the problem of air bubbles and wrinkles when the film material and the paper-insulated cotton roll are wrapped and wound.

[0040] like Figures 1 to 8As shown, in this embodiment, the tensioning module 5 includes a longitudinal rod 501, a support column 502, a boss 503, a longitudinal groove 504, a tensioning motor 505, a tensioning screw 506, a displacement block 507, and an anti-wear bearing 508. The lower end of the longitudinal rod 501 is provided with a support column 502, the middle part of the front end of the longitudinal rod 501 is provided with a boss 503, the inner side of the upper end of the longitudinal rod 501 is provided with a longitudinal groove 504, the upper end of the boss 503 is provided with a tensioning motor 505, the transmission end of the tensioning motor 505 is connected to the tensioning screw 506, the outer end of the tensioning screw 506 is threaded with a displacement block 507, and the rear end of the tensioning screw 506 is provided with an anti-wear bearing 508.

[0041] Two sets of tensioning modules 5 are symmetrically distributed on the left and right, and the two sets are equal in size and shape. The longitudinal rod 501, the support column 502, and the boss 503 are integrated into one structure. There are three support columns 502 distributed laterally. The upper end of the boss 503 is symmetrically provided with six screw holes for reinforcing the tensioning motor 505. The inner diameter of the longitudinal groove 504 is adapted to the outer diameter of the displacement block 507. The transmission end of the tensioning motor 505 and the tensioning screw 506 are interlocked, and the interlocking ends are reinforced by pins. The front thread of the tensioning screw 506 penetrates the interior of the displacement block 507 and continues to extend forward to interlock with the anti-wear bearing 508. The anti-wear bearing 508 is embedded in the rear end of the longitudinal groove 504.

[0042] During operation, the tensioning module 5 is activated. The tensioning motor 505 in the tensioning module 5 drives the tensioning screw 506 to rotate, causing the displacement block 507 to move back and forth along the longitudinal groove 504. The displacement block 507 and the fixed block 121 are reinforced together with screws, which allows the positioning module 12 to move synchronously along the displacement direction and angle of the displacement block 507. At the same time, since the positioning module 12 is wrapped inside the outer roll, the outer roll can be tightened or loosened when the positioning module 12 moves back and forth. In small-scale production, the positioning module 12 will move forward to tighten the slack caused by the contraction of the track adjustment module 3. In large-scale production, the positioning module 12 will move backward to gradually release the tension caused by the expansion of the track adjustment module 3, so that the outer roll always maintains a stable tension. This avoids the outer roll being too loose, which would prevent the felt from adhering to the film, and also avoids the outer roll being too tight, which would cause fluctuations and affect the adhesion between the felt and the film.

[0043] like Figures 1 to 10As shown, in this embodiment, the front module 7 includes a concave-convex plate 701, a reinforcing block 702, a rotating roller 703, a rotating belt 704, a rotating motor 705, and a rotating guide wheel 706. The upper end of the concave-convex plate 701 is provided with a reinforcing block 702. The rotating roller 703 is sleeved on the inner side of the reinforcing block 702. The outer end of the rotating roller 703 is provided with a rotating belt 704. The left side below the reinforcing block 702 is provided with a rotating motor 705. The front end of the rotating motor 705 is provided with a rotating guide wheel 706.

[0044] Two convex and concave plates 701 are symmetrically distributed on the left and right. Ten reinforcing blocks 702 are symmetrically installed on the upper end of the convex and concave plates 701, and the contact ends of the two are reinforced by bolts. Rotating rollers 703 are sleeved in the middle of the symmetrically distributed reinforcing blocks 702. Five rotating rollers 703 are arranged horizontally front and back. The outer right end of the foremost roller is sleeved with a traction wheel of the same size as the rotating guide wheel 706. The traction wheel and the rotating guide wheel 706 are connected by a belt. The rotating belt 704 wraps around the outer ends of the five rotating rollers 703. The rotating motor 705 is installed on the upper front side of the right end of the concave-convex plate 701. The contact end is reinforced with bolts. The transmission end of the rotating motor 705 passes through the interior of the concave-convex plate 701 and extends to the inner side. The part extending to the inner side is fitted with a rotating guide wheel 706 and reinforced with a screw pin. Furthermore, the working method of the rotating roller 703, rotating belt 704, rotating motor 705 and rotating guide wheel 706 is a known technology. Therefore, its working method will not be described in detail in this paper.

[0045] During operation, the convex and concave plates 701 extend to the inner side of the upper end of the ground rail 6, and a left-right unfolding structure is provided above the contact end. They can be fixed to the ground rail 6 by means of pins. When movement is required, they can be quickly disassembled by simply plugging and unplugging. Furthermore, the ground rail 6 allows the front module 7 to be designed to be movable, which will make subsequent maintenance more convenient and faster. At the same time, the length and size of the front module 7 can be increased according to actual production needs, which will facilitate the subsequent equipment layout.

[0046] like Figures 1 to 11 As shown, in this embodiment, the cutting module 8 includes a cutting frame 801, a closing plate 802, a rectangular block 803, a cutting motor 804, a cutting blade 805, and a support platform 806. The closing plate 802 is provided on the left and right sides of the upper end of the cutting frame 801, the rectangular block 803 is provided below the closing plate 802, the cutting motor 804 is provided in the middle of the upper end of the closing plate 802, the cutting blade 805 is provided on the inner side above the cutting frame 801, and the support platform 806 is provided below the cutting blade 805.

[0047] The cutting frame 801 is reinforced with bolts to the closing plate 802. The rectangular block 803 is embedded in the slots opened on the left and right sides of the upper end of the cutting frame 801. The cutting motor 804 is reinforced with screws to the middle of the upper end of the closing plate 802. The drive end of the cutting motor 804 is threaded through the interior of the rectangular block 803 and extends to the interior of the lower cutting frame 801. The drive end of the cutting motor 804 is sleeved with a rotary bearing at the contact end with the cutting frame 801. The cutting blade 805 is sleeved with the contact end of the rectangular block 803 and reinforced by a pin. The support platform 806 is an integral structure with the cutting frame 801. The middle of the upper end of the support platform 806 is provided with an anti-collision slot with a horizontal length equal to that of the cutting blade 805. The overall height of the support platform 806 is level with the conveying height of the upper end of the front module 7.

[0048] During operation, the cutting frame 801 and the support platform 806 can support the left and right balance of the front module 7. At the same time, the lifting and lowering working principle of the cutting module 8 is the same as that of the pressing module 4, except that the pressing is replaced by cutting. Therefore, its working principle will not be described in detail in this article. Its main purpose is to cut paper-insulated cotton rolls and film materials.

[0049] like Figures 1 to 8 As shown, in this embodiment, the positioning module 12 includes a fixing block 121, a clamping sleeve 122, a double-hole rod 123, a pulling roller 124, and a traction roller 125. The clamping sleeve 122 is provided on the inner side of the fixing block 121, the double-hole rod 123 is provided at the front end of the clamping sleeve 122, the pulling roller 124 is provided on the inner side of the upper end of the double-hole rod 123, and the traction roller 125 is provided on the inner side of the lower end of the double-hole rod 123.

[0050] The fixing block 121 and the clamping sleeve 122 are installed in a sleeved manner. The clamping sleeve 122 consists of two parts, left and right. The cylindrical structure of the left part is slightly thicker than the cylindrical structure of the right part, and the cylindrical structure of the right part can extend into the interior of the cylindrical structure of the left part. The left and right parts are reinforced with bolts. The clamping sleeve 122 and the double-hole rod 123 are reinforced with four long screws. The opening at the upper end of the double-hole rod 123 is on the same horizontal line as the inner circular hole of the clamping sleeve 122. Both ends of the pulling roller 124 pass through the upper opening of the double-hole rod 123 and extend into the interior of the clamping sleeve 122. The lower opening of the double-hole rod 123 is on the same horizontal line as the traction roller 125. At the same time, both ends of the traction roller 125 pass through the interior of the lower opening of the double-hole rod 123 and extend outwards, where they are reinforced with retaining rings and pins.

[0051] During operation, the double-hole rod 123 is reinforced with four long screws and the clamping sleeve 122, forming an integrated installation structure. The clamping sleeve 122 is also reinforced to the inside of the fixing block 121 with bolts, and the fixing block 121 and the displacement block 507 are also reinforced together with screws. This ensures that the vertical angle of the pulling roller 124 and the traction roller 125 installed in the upper and lower openings of the double-hole rod 123 does not change during the displacement of the displacement block 507. At the same time, since the positioning module 12 is wrapped inside the outer winding, the outer winding can be tightened or loosened when the positioning module 12 moves back and forth. In small-scale production, the positioning module 12 will move forward to tighten the slack of the outer winding caused by the contraction of the trajectory adjustment module 3. In large-scale production, the positioning module 12 will move backward to gradually release the tension of the outer winding caused by the expansion of the trajectory adjustment module 3, so that the outer winding always maintains a stable tension.

[0052] A method for using a binding and wrapping device for paper-insulated cotton rolls includes the following steps: Step 1: Before starting work, according to the production specifications of the paper-insulated cotton roll felt, if the specifications are larger than 800 mm, the servo motor 301 in the trajectory adjustment module 3 is started by the external control panel. The external control panel can be a known computer device. The rotation of the servo motor 301 drives the lead screw 302 to rotate synchronously, thereby driving the adjustment block 303 and the docking flange 304 to expand and displace along the groove inside the support rod 204 in the semi-circular frame 2. This adjusts and expands the trajectory radius of the multiple arc-shaped conveyor rollers 205, and expands the curvature of the outer roll wrapped around the multiple conveyor rollers 205. The multiple conveyor rollers 205 provide stable multi-point support below the outer roll. If the specifications are smaller than 800 mm, the above operation is reversed, and the curvature of the outer roll supported by the multiple conveyor rollers 205 is reduced. Step 2: After the trajectory adjustment module 3 is adjusted, the tensioning module 5 starts to work. The tensioning motor 505 in the tensioning module 5 drives the tensioning screw 506 to rotate, causing the displacement block 507 to move back and forth along the longitudinal groove 504. The displacement block 507 and the fixed block 121 are reinforced together by screws, which can drive the positioning module 12 to move synchronously along the displacement direction and angle of the displacement block 507. At the same time, since the positioning module 12 is wrapped inside the outer roll, the outer roll can be tightened or loosened when the positioning module 12 moves back and forth. In small-scale production, the positioning module 12 will move forward to tighten the slack of the outer roll caused by the contraction of the trajectory adjustment module 3. In large-scale production, the positioning module 12 will move backward to gradually release the tension of the outer roll caused by the expansion of the trajectory adjustment module 3, so that the outer roll always maintains a stable tension. Step 3: After the tensioning module 5 and positioning module 12 complete the tension adjustment of the external roll, the holding module 4 starts to work. The holding motor 404 drives the front drive shaft to rotate, thereby driving the lifting block 405 to move up and down in the lifting groove 402. This causes the holding wheel 406 installed on the outside of the lifting block 405 to move synchronously, so that the holding wheel 406 is in contact with the top of the external roll for holding. This ensures that the external roll wrapped around the outer ends of the multiple conveying rollers 205, guide rollers 102, tension rollers 124 and traction rollers 125 can always maintain a suitable angle to convey the paper-insulated cotton roll. This ensures that the tangent of the paper-insulated cotton roll and the overall movement trajectory of the film material are consistent, allowing them to fit better together. This reduces the probability of forming a flared opening on both sides during subsequent winding. At the same time, it reduces the problem of air bubbles and wrinkles when the film material and the paper-insulated cotton roll are wrapped and wound. Step 4: After the paper-clamped cotton roll is conveyed and enters the winding machine 10, the paper-clamped cotton roll is wound into a roll by the roll structure inside the winding machine 10. The binding and wrapping work is completed with the tape attached to the round rod at the front end of the winding machine 10. After the binding and wrapping is completed, it is discharged through the material discharge structure at the rear of the winding machine 10. Step 5: Lay the pre-tensioned module 5 on the left and right sides of the pre-tensioned module 5 using the ground rail 6. Then, move the pre-tensioned module 7 along the ground rail 6 and slide it to the top of the pre-tensioned module 5, where it fits against the front end of the conveyor base frame 1 with a suitable gap between them. Together with the outer roll wrapped around the multiple conveyor rollers 205, guide rollers 102, tension rollers 124, and traction rollers 125, and in conjunction with the trajectory adjustment module 3, it forms a complete arc-shaped winding and conveying structure. Compared to the traditional straight winding and conveying equipment that requires eight meters of space, the arc-shaped winding and conveying structure can reduce the total length of the equipment to within five meters, reducing the space occupancy rate. It is suitable for small and medium-sized building material factories with insufficient workshop width. Furthermore, the pre-tensioned module 7 is designed to be movable using the ground rail 6, which will make it more convenient and faster to maintain in the future. At the same time, the length and size of the pre-tensioned module 7 can be increased according to actual production needs, which will facilitate the subsequent equipment layout. Step 6: The bottom film material can be placed on the inside for installation using the film support 9, so that it can be placed during subsequent production. The cutting module 8 has a support platform 806 on its inside that matches the conveying height of the front module 7. Once the paper-clamped cotton roll reaches the appropriate length, the cutting motor 804 drives the cutting blade 805 to move downwards to complete the cutting of the paper-clamped cotton roll.

[0053] The motors used in this article are all AC asynchronous motors that can rotate in both directions, and are the most commonly used in current industrial scenarios.

[0054] The working principle of the technical solution provided by this invention is as follows: First, before starting work, according to the production specifications of the paper-clamped cotton roll felt, the servo motor 301 in the trajectory adjustment module 3 is controlled by the external operating console to start working. The servo motor 301 drives the lead screw 302 to rotate synchronously, thereby driving the adjustment block 303 and the docking flange 304 to expand or contract along the groove inside the support rod 204 in the semi-circular frame 2. This adjusts the trajectory radius of the multiple arc-shaped conveyor rollers 205 assembled with the docking flange 304 to expand or contract, achieving a suitable trajectory radius. Then, by setting... The tensioning module 5 starts working, with the tensioning motor 505 in the tensioning module 5 driving the tensioning screw 506 to rotate, causing the displacement block 507 to move back and forth along the longitudinal groove 504. The displacement block 507 and the fixed block 121 are reinforced together with screws, which can drive the positioning module 12 to move synchronously along the displacement direction and angle of the displacement block 507. At the same time, since the positioning module 12 is wrapped inside the outer tape, the outer tape can be tightened or loosened when the positioning module 12 moves back and forth. In small-scale production, the positioning module 12 will move forward. The displacement tightens the outer tape caused by the contraction of the track adjustment module 3. During large-scale production, the positioning module 12 moves backward to gradually release the tension caused by the expansion of the track adjustment module 3. Then, the pressure motor 404 starts working, driving the lifting block 405, which is pierced by the drive shaft, to move up and down in the lifting groove 402. This causes the pressure roller 406, installed on the outside of the lifting block 405, to move synchronously, pressing against the top of the outer tape and ensuring it is properly secured. This tightens the tape wrapped around the multiple conveyor rollers 205 and guide rollers 102. The outer winding of the pull roller 124 and the traction roller 125 can always maintain a suitable angle to convey the paper-clamped cotton roll felt. After the paper-clamped cotton roll felt is conveyed and enters the winding machine 10, the rolling structure inside the winding machine 10 winds the paper-clamped cotton roll felt into a roll. The tape sleeved on the round rod at the front end of the winding machine 10 completes the binding and wrapping work. After the binding and wrapping is completed, it is discharged through the unloading structure at the rear of the winding machine 10. While binding and wrapping, when the paper-clamped cotton roll felt reaches a suitable length, the cutting motor 804 drives the cutting blade 805 to move downward to complete the cutting work of the paper-clamped cotton roll felt.

This expands the trajectory radius of the multiple arc-shaped conveyor rollers and increases the curvature of the outer roll wrapped around the multiple conveyor rollers. The multiple conveyor rollers provide stable multi-point support below the outer roll. If the specifications are smaller than 800 mm, the above operation is reversed to reduce the curvature of the outer roll supported by the multiple conveyor rollers. Step 2: After the trajectory adjustment module is adjusted, the tensioning module starts working. The tensioning motor in the tensioning module drives the tensioning screw to rotate, allowing the displacement block to move back and forth along the longitudinal groove. The displacement block and the fixed block are reinforced together with screws, which can drive the positioning module to move synchronously along the displacement direction and angle of the displacement block. At the same time, since the positioning module is wrapped inside the outer roll, the outer roll can be tightened or loosened when the positioning module moves back and forth. In small-scale production, the positioning module will move forward to tighten the slack caused by the contraction of the trajectory adjustment module. In large-scale production, the positioning module will move backward to gradually release the tension caused by the expansion of the trajectory adjustment module, so that the outer roll always maintains a stable tension. Step 3: After the tensioning module and positioning module complete the tension adjustment of the external roll, the holding module starts to work. The holding motor drives the front drive shaft to rotate, thereby causing the lifting block to move up and down in the lifting groove. This causes the holding rollers installed on the outside of the lifting block to move synchronously, so that the holding rollers are pressed against the top of the external roll. This ensures that the external roll wrapped around the outer ends of multiple conveyor rollers, guide rollers, tension rollers and traction rollers can always maintain a suitable angle to convey the paper-insulated cotton roll. This ensures that the paper-insulated cotton roll and the overall movement trajectory tangent of the film material are consistent, allowing them to fit better together. This reduces the probability of the two sides forming a flared opening during subsequent winding, and also reduces the problem of air bubbles and wrinkles when the film material and the paper-insulated cotton roll are wrapped and wound. Step 4: After the paper-insulated cotton roll is fed into the winding machine, the roll structure inside the winding machine winds the paper-insulated cotton roll into a roll. The tape attached to the round rod at the front of the winding machine completes the binding and wrapping work. After binding and wrapping, it is discharged through the unloading structure at the rear of the winding machine. Step 5: Lay the pre-mounted module on both sides of the tensioning module using the set ground rails. Then, move the pre-mounted module along the ground rails, sliding it to the top of the tensioning module and aligning it with the front end of the conveyor base, leaving a suitable gap. Together with the external roll wrapped around the multiple conveyor rollers, guide rollers, tension rollers, and traction rollers, and in conjunction with the track adjustment module, it forms a complete arc-shaped winding conveyor structure. Compared to the traditional straight winding conveyor equipment that requires eight meters of space, the arc-shaped winding conveyor structure can reduce the total length of the equipment to within five meters, reducing the space occupancy rate. This is suitable for small and medium-sized building material factories with insufficient workshop width. Furthermore, the pre-mounted module is designed to be movable using the ground rails, making subsequent maintenance more convenient and faster. At the same time, the length and size of the pre-mounted module can be adjusted according to actual production needs, providing convenience for subsequent equipment layout. Step 6: The bottom film material can be placed on the inside for installation using the film-laying support, so that it can be laid out during subsequent production. The cutting module has a support platform on its inside that matches the conveying height of the front module. Once the paper-clamped cotton roll reaches the appropriate length, the cutting motor drives the cutting blade to move downwards to complete the cutting of the paper-clamped cotton roll.
