Description

Technical Field

[0001] The invention relates to the technical field of plastic-steel strip production equipment, in particular to a winding and traction device for producing PET plastic-steel strips. Background Art

[0002] In the existing PET plastic-steel tape production process, the winding and traction device is a key piece of production equipment. Its main function is to efficiently wind the produced PET plastic-steel tape into rolls for subsequent transportation and packaging. However, traditional winding and traction devices have several technical issues, such as the inability to automatically adjust the pressure of the traction roller based on real-time changes in the PET plastic-steel tape (such as thickness, material, and winding speed). This can cause the plastic-steel tape to wrinkle, stretch, deform, or break during the winding process, affecting product quality and consistency. Furthermore, traditional devices often require manual intervention to adjust the tension, which not only increases the workload of operators but also increases the risk of equipment failure and production accidents caused by human error.

[0003] In terms of cleaning, traditional equipment often lacks effective cleaning mechanisms, resulting in the accumulation of dust and impurities on the surface of the plastic-steel belt during the winding process, which may cause surface scratches, quality degradation, or defects in subsequent processing. Although some equipment uses cleaning tools or dust removal equipment, these devices are often complex, costly, difficult to maintain, and may cause secondary contamination of the plastic-steel belt.

[0004] During the rewinding process, when a set of rewinding rollers is full, traditional equipment usually needs to be stopped to replace the rewinding rollers, which not only reduces production efficiency but also affects equipment utilization. In addition, the downtime for replacement may cause damage to the PET plastic steel strip, affecting product quality.

[0005] Therefore, those skilled in the art have proposed a winding and traction device for producing PET plastic steel strips to solve the above problems. Summary of the Invention

[0006] In view of the deficiencies in the prior art, the present invention provides a winding and traction device for the production of PET plastic steel strips, which solves the problems raised in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a winding and traction device for producing PET plastic steel strips, comprising a frame, wherein the left and right sides of the frame are fixedly connected to a connecting frame, the outer surface of the connecting frame is provided with a plurality of slide grooves, the inner wall of the slide groove is slidably connected to a movable frame, the inner side of the connecting frame is movably connected to an adjusting roller 2 through a bearing, the inner side of the movable frame is movably connected to an adjusting roller 1 through a bearing, a driving screw is rotatably installed on the outer side of the connecting frame, the outer surface of the driving screw is threadedly connected to a threaded sleeve, the outer side of the threaded sleeve is fixedly connected to the outer side of the movable frame, a double-axis motor is fixedly installed on the outer side of the connecting frame, one of the output ends of the double-axis motor is fixedly connected to one end of one of the adjusting rollers 2, and a cleaning component is installed on one side of the connecting frame, and the cleaning component is used to clean dust on the surface of the plastic steel strip.

[0008] The above-described technical solution, through the sliding cooperation of the connecting frame and the movable frame on the frame, as well as the precise control of the first and second adjusting rollers, automatically adjusts the tension of the PET plastic steel strip during the winding process, ensuring the stability and consistency of the winding quality. The threaded connection between the drive screw and the threaded sleeve enables the movable frame to move precisely, thereby adjusting the distance between the first and second adjusting rollers. The driving action of the dual-axis motor further enhances the flexibility and accuracy of the adjustment. In addition, the cleaning component on the device effectively removes dust from the surface of the plastic steel strip, preventing dust from damaging the strip during the winding process or affecting the quality of subsequent processing, thereby improving the production efficiency and product quality of the PET plastic steel strip.

[0009] Preferably, the cleaning assembly includes a pair of cleaning rollers rotatably mounted on the outside of the connecting frame, the bottom of the connecting frame is fixedly connected to a fixed cylinder, the interior of the fixed cylinder is slidably connected to a rubber piston, the outside of the rubber piston is fixedly connected to a movable rod, the outer surface of the fixed cylinder is connected to an air intake pipe and a connecting pipe in sequence, the outer side of the connecting pipe is connected to connecting pipe 2, the outer surface of connecting pipe 2 is connected to multiple dust suction pipes, and one end of the dust suction pipe is connected to a collection bucket through connecting pipe 1.

[0010] The above technical solution removes dust and impurities from the surface of the plastic-steel strip through the rotation of the cleaning roller, preventing these contaminants from accumulating during rewinding, thereby avoiding damage to the plastic-steel strip or affecting the quality of subsequent processing. The combination of the rubber piston and the movable rod creates air pressure changes inside the fixed cylinder. Utilizing the Bernoulli principle, suction is generated through the dust collection tube, sucking in dust from the cleaning roller and collecting it in the collection bucket. This not only improves cleaning efficiency but also reduces secondary contamination of the plastic-steel strip, ensuring the surface cleanliness of the PET plastic-steel strip and improving the quality of the final product.

[0011] Preferably, one-way valves are installed inside the air intake pipe and the connecting pipe, and the conduction directions of the two one-way valves are opposite.

[0012] This technical solution ensures that airflow within the fixed cylinder flows in a predetermined direction. One one-way valve allows air to enter the fixed cylinder, creating positive pressure, while the other one-way valve allows air to exit, creating negative pressure. This design utilizes the directional flow of air to control the movement of the rubber piston, thereby adjusting the suction force of the cleaning component, optimizing dust and impurity removal efficiency and ensuring stable and effective operation of the cleaning component.

[0013] Preferably, the other output end of the dual-axis motor is fixedly connected to bevel gear 1, a transmission rod is rotatably installed on the outer side of the connecting frame, both ends of the transmission rod are fixedly connected to bevel gear 2, and the bottom end of the driving screw is fixedly connected to bevel gear 3.

[0014] Through this technical solution, the rotational motion of the dual-axis motor is transmitted to the drive screw, achieving precise control of the position of the movable frame and the adjusting roller on it. Through the meshing transmission of the bevel gears, the rotation direction and speed of the drive screw can be changed, thereby adjusting the movement of the threaded sleeve along the drive screw, achieving automatic adjustment of the tension of the PET plastic steel strip during the winding process, ensuring stable and consistent winding quality.

[0015] Preferably, the outer side of the bevel gear three is meshedly connected with the outer side of one of the bevel gears two, and the outer side of the bevel gear one is meshedly connected with the outer side of the other bevel gear two.

[0016] Through the above technical solution, the rotational motion of the dual-axis motor 508 is effectively transmitted to the drive screw 506. This gear configuration allows the rotation of the motor to drive the transmission rod 703 through the bevel gear 1 701, which in turn rotates the bevel gear 2 702, and its rotational motion is transmitted to the drive screw 506 through the meshing bevel gear 3 704.

[0017] Preferably, a driving motor is fixedly installed on the outer side of the frame, the output end of the driving motor is fixedly connected to a mounting frame, a plurality of winding rollers are rotatably installed on the inner side of the mounting frame, a motor for driving the winding rollers is installed on the outer side of the mounting frame, and a plurality of manipulators are installed on the top of the frame.

[0018] Through the above technical solution, the drive motor fixedly installed on the outside of the frame drives the multiple winding rollers on the inside to rotate through the mounting frame connected to its output end, thereby realizing the winding operation of the PET plastic-steel strip, and the motor on the outside of the mounting frame is specifically responsible for driving these winding rollers to ensure a smooth and efficient winding process; at the same time, multiple manipulators installed on the top of the frame are used to automatically transfer and cut the plastic-steel strip after the winding roller is full. In this way, the entire device can realize automatic continuous winding operations without manual intervention, significantly improving production efficiency and the level of automation of operations.

[0019] Preferably, two laser cutting devices are installed on the outside of the frame, and the laser cutting devices are used to cut the plastic-steel belt after winding.

[0020] Through the above technical solution, the two laser cutting devices installed on the outside of the frame are used to automatically and accurately cut the PET plastic-steel strip after it is wound, thereby realizing fixed-length cutting and separation of the plastic-steel strip, ensuring the specification consistency of each roll of plastic-steel strip, improving production efficiency, and avoiding material damage or burrs that may be caused by traditional mechanical cutting, ensuring the cutting quality of the plastic-steel strip and the convenience of subsequent use or packaging.

[0021] Preferably, one end of the adjusting roller 2 is fixedly connected to a sector gear, the outer side of the connecting frame is fixedly connected to a fixed plate, the inner side of the fixed plate is slidably connected to a movable plate, and the upper and lower sides of the movable plate are fixedly connected to racks.

[0022] Through the above technical solution, the rotational motion of the adjusting roller 2 is converted into the linear motion of the movable plate, and then the pressure between the adjusting rollers 1 and 2 is precisely controlled through the engagement of the rack and the sector gear, thereby realizing automatic adjustment of the tension of the PET plastic-steel belt to adapt to plastic-steel belts of different thicknesses and materials, thereby ensuring the stability and consistency of the winding quality.

[0023] Preferably, outer sides of the two racks are meshedly connected with the outer side of the sector gear, and the end of the movable plate is fixedly connected to one end of the movable rod.

[0024] With the above technical solution, when the sector gear rotates, it drives the two racks to move synchronously, thereby pushing the movable plate to slide along the fixed plate. Since the movable plate is fixedly connected to the movable rod, the movement of the movable plate further drives the movement of the movable rod.

[0025] Preferably, the cross-sectional area of ​​the fixing tube is larger than the cross-sectional area of ​​the second connecting tube.

[0026] Through the above technical solution, the Bernoulli effect in fluid mechanics is utilized to generate an air pressure difference when the rubber piston moves, thereby forming a low-pressure area in the connecting pipe 2, enhancing the suction force of the dust suction pipe, and improving the efficiency of the cleaning component in cleaning dust on the surface of the PET plastic steel belt, thereby ensuring the effectiveness of the cleaning process.

[0027] The present invention provides a winding and traction device for the production of PET plastic steel strips, which has the following beneficial effects: 1. The present invention can accurately adjust the pressure of the traction roller according to the real-time changes in the thickness, material, and winding speed of the PET plastic-steel strip, thereby ensuring that the plastic-steel strip always maintains stable tension during the winding process, effectively avoiding problems such as wrinkling, stretching deformation, or breakage of the plastic-steel strip caused by uneven tension, and significantly improving the quality and consistency of the product. Secondly, the automatic adjustment function reduces the frequency and complexity of manual intervention, reduces the workload of operators and their reliance on operational skills, and also reduces the risk of equipment failure and production accidents caused by human operational errors, greatly improving production efficiency and equipment operation reliability.

[0028] 2. The cleaning roller of the present invention can promptly remove dust and impurities from the surface of the plastic-steel strip, preventing dust accumulation during the winding process that could lead to scratches on the strip, quality degradation, or defects in subsequent processing. Furthermore, the design utilizes the Bernoulli principle for dust absorption, eliminating the need for additional cleaning tools or complex dust removal equipment. This not only simplifies the device structure, reduces equipment costs and maintenance, but also improves cleaning efficiency and reduces the risk of secondary contamination of the plastic-steel strip during the cleaning process.

[0029] 3. This invention achieves a continuous and automated winding process by arranging multiple winding rollers, in conjunction with laser cutting equipment and a robotic arm. When one set of winding rollers is full, the laser cutting equipment quickly cuts the steel strip, and the robotic arm immediately winds the strip onto another idle winding roller, eliminating the need for downtime for replacement. This effectively avoids the production interruption caused by changing winding rollers during the traditional winding process, significantly improving production efficiency and equipment utilization.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. 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 making creative efforts are within the scope of protection of the present invention.

[0033] Please see the attached Figure 1 - Attachment Figure 9 The embodiment of the present invention provides a winding and traction device for the production of PET plastic-steel strips, including a frame 1, wherein a connecting frame 503 is fixedly connected to the left and right sides of the frame 1, a plurality of slide grooves 505 are provided on the outer surface of the connecting frame 503, and a movable frame 504 is slidably connected to the inner wall of the slide groove 505, and the inner side of the connecting frame 503 is movably connected to the adjusting roller 2 502 through a bearing, and the inner side of the movable frame 504 is movably connected to the adjusting roller 1 501 through a bearing, and a driving screw 506 is rotatably installed on the outer side of the connecting frame 503, and the outer surface of the driving screw 506 is threadedly connected to a threaded sleeve 507, and the outer side of the threaded sleeve 507 is fixedly connected to the outer side of the movable frame 504, and a dual-axis motor 508 is fixedly installed on the outer side of the connecting frame 503, and one of the output ends of the dual-axis motor 508 is fixedly connected to one end of one of the adjusting rollers 2 502, and a cleaning component is installed on one side of the connecting frame 503, and the cleaning component is used to clean dust on the surface of the plastic-steel strip.

[0034] Specifically, the movable frame 504 is slidably connected to the inner wall of the chute 505, enabling left and right movement on the connecting frame 503. This design allows the position of the adjusting roller 1 501 to be adjusted according to the thickness and material of the plastic-steel strip to accommodate different winding requirements. Adjusting roller 1 501 and adjusting roller 2 502 are movably connected to the inner sides of the movable frame 504 and the connecting frame 503, respectively, via bearings, for direct contact with the plastic-steel strip and control of its tension. The position of adjusting roller 2 502 can be precisely controlled by the output of the dual-axis motor 508, thereby automatically adjusting the tension of the plastic-steel strip. The rotation of the drive screw 506, through a threaded connection, drives the threaded sleeve 507 along the screw. This threaded transmission mechanism enables the movable frame 504 to precisely adjust its position, thereby varying the distance between adjusting roller 1 501 and adjusting roller 2 502, achieving precise control of the plastic-steel strip tension. The cleaning assembly automatically cleans dust from the surface of the plastic-steel strip during the winding process, preventing dust accumulation and affecting product quality. The cleaning component generates air pressure changes through the reciprocating motion of the rubber piston 410, and uses the Bernoulli principle to generate suction in the dust suction pipe 409, sucking in the dust on the cleaning roller 403 and discharging it into the collection bucket 401 through the air flow, reducing secondary pollution to the plastic steel belt.

[0035] The cleaning assembly includes a pair of cleaning rollers 403 rotatably mounted on the outside of a connecting frame 503. A fixed cylinder 404 is fixedly connected to the bottom of the connecting frame 503. A rubber piston 410 is slidably connected to the interior of the fixed cylinder 404. A movable rod 407 is fixedly connected to the exterior of the rubber piston 410. The exterior of the fixed cylinder 404 is connected in sequence to an air intake pipe 406 and a connecting pipe 408. The exterior of the connecting pipe 408 is connected to a second connecting pipe 405. The exterior of the second connecting pipe 405 is connected to multiple dust collection pipes 409. One end of each dust collection pipe 409 is connected to a collection bucket 401 via a first connecting pipe 402. Both the air intake pipe 406 and the connecting pipe 408 are internally mounted with a one-way valve, with the two one-way valves opening in opposite directions.

[0036] Specifically, the cleaning roller 403 rolls during the winding process of the plastic-steel strip, directly contacting the strip surface and removing dust and impurities through physical friction. The fixed cylinder 404 is mounted at the bottom of the connecting frame 503 and contains a rubber piston that slides inside. The reciprocating motion of the rubber piston changes the air pressure inside the fixed cylinder 404. This is achieved by the movement of the movable rod 407, which in turn affects the suction force of the dust suction pipe 409. The movement of the movable rod 407 directly causes the rubber piston to slide inside the fixed cylinder 404, thereby changing the internal air pressure. The air inlet pipe 406 and the connecting pipe 408 are respectively connected to the outer surface of the fixed cylinder 404 to control the air flow entering the fixed cylinder 404. The air inlet pipe 406 allows air to enter, while the connecting pipe 408 releases air. The internally installed one-way valve ensures that air can only flow in one direction, preventing air short-circuiting and ensuring the effectiveness of the air pressure change. Installed inside the air inlet pipe 406 and the connecting pipe 408, it ensures that air can only flow in one direction. The two one-way valves have opposite conduction directions, one allowing air to enter the fixed cylinder 404 and the other allowing air to be discharged. This design helps to establish a stable air pressure difference in the fixed cylinder 404, thereby generating suction in the dust collection tube 409.

[0037] The other output end of the dual-axis motor 508 is fixedly connected to bevel gear 1 701. A transmission rod 703 is rotatably mounted on the outside of the connecting frame 503. Both ends of the transmission rod 703 are fixedly connected to bevel gear 2 702. The bottom end of the drive screw 506 is fixedly connected to bevel gear 3 704. The outer side of bevel gear 3 704 meshes with the outer side of one of bevel gear 2 702, and the outer side of bevel gear 1 701 meshes with the outer side of the other bevel gear 2 702.

[0038] Specifically, when the dual-axis motor 508 is activated, its output drives bevel gear 1 701 to rotate, which in turn, through the meshing of bevel gear 2 702, rotates the drive rod 703. The rotation of the drive rod 703 causes the bevel gears 2 702 at both ends to rotate. One of the bevel gears 2 702 drives bevel gear 3 704 to rotate, thereby driving the screw 506. The rotation of the drive screw 506, through the movement of the threaded sleeve 507, achieves precise control of the distance between the adjusting roller 1 501 and the adjusting roller 2 502, thereby precisely adjusting the tension of the plastic-steel belt.

[0039] A driving motor 302 is fixedly installed on the outside of the frame 1, and the output end of the driving motor 302 is fixedly connected to the mounting frame 301. A plurality of winding rollers 303 are rotatably installed on the inside of the mounting frame 301. A motor for driving the winding rollers 303 is installed on the outside of the mounting frame 301. A plurality of manipulators 304 are installed on the top of the frame 1.

[0040] Two laser cutting devices 2 are installed on the outside of the frame 1, and the laser cutting devices 2 are used to cut the plastic-steel strip after winding.

[0041] Specifically, a winding roller 303 is mounted on the inner side of the mounting frame 301 and is used to roll the plastic-steel strip into a roll. The rotation of the winding roller 303 is driven by a motor mounted on the outer side of the mounting frame 301. The motor adjusts the speed according to production requirements to accommodate the winding of plastic-steel strips of different speeds and thicknesses. A manipulator 304 is mounted on the top of the frame 1 and is used to automatically transfer the plastic-steel strip during the winding process. When one winding roller 303 completes winding, the manipulator 304 can automatically transfer the plastic-steel strip to another idle winding roller 303, achieving continuous production without manual intervention, thereby improving production efficiency and the degree of automation. The laser cutting device 2 is mounted on the outer side of the frame 1 and is used to perform precise cutting after the plastic-steel strip is wound. The laser cutting device 2 can quickly and accurately cut the strip without contacting the plastic-steel strip, avoiding the damage and pollution that may be caused by traditional cutting methods, and improving cutting quality and production safety.

[0042] The end of one of the second adjustment rollers 502 is fixedly connected to a sector gear 603. A fixed plate 601 is fixedly connected to the outside of the connecting frame 503. A movable plate 602 is slidably connected to the inside of the fixed plate 601. Racks 604 are fixedly connected to the upper and lower sides of the movable plate 602. The outer sides of both racks 604 mesh with the outer sides of the sector gear 603. The end of the movable plate 602 is fixedly connected to one end of the movable rod 407. The cross-sectional area of ​​the fixed tube 404 is larger than that of the second connecting tube 405.

[0043] Specifically, the rack 604 meshes with the outer side of the sector gear 603. When the sector gear 603 rotates, it meshes with the rack 604, driving the movable plate 602 to slide along the fixed plate 601, thereby adjusting the position of the adjusting roller 1 501. The end of the movable plate 602 is fixedly connected to one end of the movable rod 407. The movement of the movable rod 407 directly causes the rubber piston 410 to move within the fixed cylinder 404, thereby changing the air pressure within the fixed cylinder 404 and controlling the suction force of the dust suction pipe 409. The cross-sectional area of ​​the fixed cylinder 404 is larger than that of the connecting pipe 2 405. This design utilizes the Bernoulli principle in fluid mechanics. When the rubber piston 410 moves, the change in air pressure within the fixed cylinder 404 causes the air flow rate to increase, forming a low-pressure area within the connecting pipe 2 405, generating suction, and sucking dust from the cleaning roller 403 into the collection bucket 401 through the dust suction pipe 409.

[0044] Working Principle: First, the PET plastic-steel strip to be wound passes through the inside of the cleaning roller 403 and the second adjusting roller 502 in sequence, and is finally wrapped around the outside of the winding roller 303. The motor outside the winding roller 303 is activated to begin winding the PET plastic-steel strip. During the winding process, the dual-axis motor 508 is activated, driving the second adjusting roller 502 to rotate, assisting in pulling the plastic-steel strip. Simultaneously, the cleaning roller 403 rotates to clean the surface of the plastic-steel strip.

[0045] The rotation of the end of the second adjusting roller 502 drives the sector gear 603, which in turn intermittently meshes with the two racks 604, prompting the movable plate 602 to reciprocate left and right along the inner wall of the fixed plate 601. The movement of the movable plate 602 drives the movable rod 407 to move synchronously, which in turn causes the rubber piston 410 to move along the inner wall of the fixed cylinder 404, causing the air pressure inside the fixed cylinder 404 to change. When the rubber piston 410 moves away from the movable rod 407, the air flow rate increases when entering the second connecting tube 405 because the cross-sectional area of ​​the fixed cylinder 404 is larger than that of the second connecting tube 405. According to Bernoulli's principle, the increased flow rate causes the pressure to decrease, thus forming a low pressure in the second connecting tube 405. This creates suction in the dust collection tube 409, sucking in dust from the cleaning roller 403 and discharging it into the collection bucket 401 through the airflow, thereby reducing secondary contamination of the plastic-steel belt.

[0046] During the winding process, pressure sensors installed inside adjusting roller 1 501 and adjusting roller 2 502 monitor the pressure of the plastic-steel strip in real time and transmit the data to the control terminal. The control terminal activates the other output of the dual-axis motor 508, rotating bevel gear 1 701, which in turn drives bevel gear 2 702. Driven by the transmission rod 703, the drive screw 506 rotates, and the threaded sleeve 507 moves along the outer surface of the drive screw 506, driving the synchronous movement of adjusting roller 1 501. By adjusting the spacing between adjusting rollers 2 502, the traction force of the plastic-steel strip can be precisely adjusted.

[0047] When one winding roller 303 has finished winding, the laser cutting device 2 cuts the plastic-steel strip. Subsequently, the drive motor 302 is activated, driving the mounting frame 301 to rotate, causing the remaining idle winding roller 303 to move to the workstation. The robot 304 then winds the plastic-steel strip onto the new winding roller 303 without requiring downtime for replacement. This effectively avoids the production interruption caused by changing the winding roller 303 during the traditional winding process, significantly improving production efficiency and equipment utilization.
