Description

Technical Field

[0001] This invention relates to the field of tape production technology, specifically to a tape winding device with an automatic unloading roller mechanism. Background Technology

[0002] A tape winding device is a piece of equipment used to wind tape or other rolls of materials. It typically consists of a support frame, a winding shaft, and a transmission mechanism. Users secure the tape to the winding shaft and then rotate the shaft via the transmission mechanism, causing the tape to gradually wind around it, achieving the winding purpose. Tape winding devices are widely used in packaging, printing, electronics, pharmaceuticals, and other fields, improving work efficiency, reducing manual labor, and ensuring tape winding quality.

[0003] Existing tape winding devices primarily rely on the active rotation of a winding shaft to wind the tape. During installation, the winding roller requires connecting the two ends of the shaft to a bearing bracket and then to a drive motor via pulleys and other transmission structures. This process necessitates manual removal after winding, which is cumbersome. Furthermore, the increased weight of the winding roller after winding adds to the time and effort required. Additionally, the rigid connection between the winding roller and the motor necessitates maintaining a constant relationship between tape tension and winding speed during winding. Low tension leads to tape bending and sticking, while high tension, coupled with the rigid drive of the winding roller and motor to maintain a constant winding speed, can result in significant tensile deformation or even breakage. Therefore, this research aims to address these issues by providing a tape winding device with an automatic unwinding roller mechanism. This technology seeks to solve the problems and enhance the device's practical value. Summary of the Invention

The wheel assembly includes a main wheel disc and ear discs rotatably connected to both ends of the bottom surface of the main wheel disc. The other ends of the two ear discs are provided with mutually compatible fasteners. The surfaces of the main wheel disc and the ear discs are fixedly mounted with annular roller edges. The inner side of the roller edges slides against the surface of the hanging wheels. The surfaces of the main wheel disc and the ear discs are in transmission contact with the surface of the transmission wheel. The inner sides of the main wheel disc and the ear discs are fixedly mounted with elastic abutment rods and a gripping belt. One end of the elastic abutment rod abuts against the surface of the gripping belt.

[0007] In a preferred embodiment, the present invention may be further configured such that: a transmission box is fixedly installed on one side of the winding frame, and the surface of the transmission box is provided with a plurality of synchronous shafts for synchronous transmission rotation, and the transmission wheel is fixedly sleeved on the surface of the synchronous shafts.

[0008] In a preferred embodiment, the present invention can be further configured such that: the number of transmission wheels is several, and the transmission wheels are arranged in a one-to-one correspondence with the synchronous shafts; the synchronous shafts are arranged relatively perpendicularly between the two drive components; and the inner side of the transmission box is provided with a pulley set for synchronizing the rotation of each synchronous shaft.

[0009] In a preferred embodiment, the present invention may be further configured such that: the hanging wheel on the surface of the hanging seat abuts against the inner circumference of the roller edge, and the hanging wheels on the surface of the gripper bar are symmetrically arranged on both sides of the roller edge.

[0010] In a preferred embodiment, the present invention can be further configured such that the drive cylinder is a hydraulic cylinder structure, and the gripper rod and the drive cylinder are symmetrically arranged at both ends of the bottom surface of the machine base.

[0011] In a preferred embodiment, the present invention can be further configured such that: the main wheel and the two ear plates are connected end to end to form a disc-shaped structure, the ear plates are symmetrically arranged on both sides of the bottom surface of the main wheel about the center line of the main wheel, and the elastic abutment and the retaining belt are symmetrically arranged about the center line of the main wheel.

[0012] In a preferred embodiment, the present invention can be further configured such that: one end of the retaining strap is fixedly connected to the bottom surface of the main wheel and the connection point is located on the vertical midline of the main wheel; the other end of the retaining strap is fixedly connected to the end of the ear plate away from the main wheel; the retaining strap is a flexible rubber plate structure; and the elastic abutment is an elastic telescopic rod structure and abuts against one side of the retaining strap.

[0014] The beneficial effects achieved by this invention are as follows:

[0015] 1. In this invention, a novel hoisting installation structure is set up, and the winding roller is fixed by the drive assembly and the wheel sleeve assembly.

The installation and operation are simple, and the roller can be automatically unloaded after winding, which improves work efficiency.

[0016] 2. In this invention, the flexible deformation movement of the main wheel and the inner clamping belt of the ear plate in different states of the ear plate is used to wrap and clamp the take-up roller to achieve the positioning of the take-up roller. The flexible wrapping and frictional contact of the clamping belt, combined with the active rotation of the wheel sleeve assembly, realizes the transmission of the take-up roller, and achieves one-click installation and transmission connection.

[0017] 3. In this invention, by setting up a clamping belt and a friction drive between the take-up roller and the surface of the take-up roller, slippage occurs between the take-up roller and the clamping belt when the take-up tension is large, thereby avoiding the stretching deformation and breakage of the tape caused by the rigid drive of the take-up roller. Furthermore, a tension positioning component is arranged on the surface of the take-up frame to guide the tape and provide a constant tension at the take-up end, thus preventing the tape from sticking together.

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0031] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a tape winding device with an automatic unloading roller mechanism.

[0032] Combination Figure 1-7 As shown, the present invention provides a tape winding device with an automatic lower roller mechanism, comprising: a winding frame 100, a drive assembly 200 and a wheel sleeve assembly 300. A drive motor 110 is fixedly mounted on the surface of the winding frame 100. The drive assembly 200 and the wheel sleeve assembly 300 are arranged in two sets on the left and right sides of the winding frame 100. A tension positioning assembly 120 for guiding the tape into the inner side of the winding frame 100 is fixedly mounted on the top surface of the winding frame 100.

[0033] The drive assembly 200 includes a base 210, a gripper bar 220, and a drive cylinder 230. One end of the gripper bar 220 is rotatably connected to the bottom end of the base 210, and both ends of the drive cylinder 230 are movably connected to the surfaces of the base 210 and the gripper bar 220, respectively. The bottom surface of the base 210 is provided with a transmission wheel 211 and a hanging seat 212. The surfaces of the hanging seat 212 and the gripper bar 220 are each provided with a plurality of hanging wheels 221. The wheel sleeve assembly 300 includes a main wheel disc 310 and lugs rotatably connected to both ends of the bottom surface of the main wheel disc 310. The disc 320 has two ear discs 320 with matching fasteners at their other ends. The surfaces of the main disc 310 and ear discs 320 are fixedly mounted with annular roller edges 350. The inner side of the roller edges 350 slides against the surface of the hanging wheel 221. The surfaces of the main disc 310 and ear discs 320 drive against the surface of the transmission wheel 211. The inner sides of the main disc 310 and ear discs 320 are fixedly mounted with elastic abutment rods 330 and clamping belts 340. One end of the elastic abutment rod 330 abuts against the surface of the clamping belt 340.

[0034] In this embodiment, a transmission box 400 is fixedly installed on one side of the winding frame 100, and the surface of the transmission box 400 is provided with a plurality of synchronous shafts 410 that rotate synchronously. The transmission wheel 211 is fixedly sleeved on the surface of the synchronous shafts 410.

[0035] Furthermore, there are several transmission wheels 211, and each transmission wheel 211 is arranged in a one-to-one correspondence with a synchronous shaft 410. The synchronous shaft 410 is arranged relatively perpendicularly between the two drive components 200. The inner side of the transmission box 400 is provided with a pulley set for synchronizing the rotation of each synchronous shaft 410.

[0036] Specifically, the synchronous shaft 410 is driven by the internal belt pulley, which makes each synchronous shaft 410 rotate synchronously. The synchronous shaft 410 is connected to the transmission wheel 211 on the surface of the base 210 on both sides of the winding frame 100 to realize the synchronous rotation of the transmission wheel 211 on the surface of the drive assembly 200 on both sides and the wheel sleeve assembly 300, thereby realizing the drive at both ends of the winding roller.

[0037] In this embodiment, the rollers 221 on the surface of the hanger 212 abut against the inner circumference of the roller edge 350, and the rollers 221 on the surface of the gripper bar 220 are symmetrically arranged on both sides of the roller edge 350.

[0038] Specifically, the wheel assembly 300 is hoisted and arranged by the wheel 221 on the surface of the hanger 212, and the wheel assembly 300 can rotate freely on the surface of the hanger 212.

[0039] In this embodiment, the drive cylinder 230 is a hydraulic cylinder structure, and the gripper rod 220 and the drive cylinder 230 are symmetrically arranged at both ends of the bottom surface of the machine base.

[0040] In this embodiment, the main wheel 310 and the two ear plates 320 are connected end to end to form a disc-shaped structure. The ear plates 320 are symmetrically arranged on both sides of the bottom surface of the main wheel 310 about the center line of the main wheel 310. The elastic abutment rod 330 and the retaining belt 340 are symmetrically arranged about the center line of the main wheel 310.

[0041] Furthermore, one end of the retaining strap 340 is fixedly connected to the bottom surface of the main wheel 310 and the connection point is located on the vertical midline of the main wheel 310. The other end of the retaining strap 340 is fixedly connected to the end of the ear plate 320 away from the main wheel 310. The retaining strap 340 is a flexible rubber plate structure, and the elastic abutment rod 330 is an elastic telescopic rod structure that abuts against one side of the retaining strap 340.

[0042] Specifically, the elastic recovery and elastic contact of the clamping belt 340 make the clamping belt 340 fit tightly against the surface of the take-up roller, thereby achieving clamping and holding of the take-up roller. When the winding tension is large, slippage occurs between the take-up roller and the clamping belt 340, thus avoiding the stretching deformation and breakage of the tape caused by the rigid transmission of the take-up roller.

[0043] In this embodiment, the tension positioning assembly 120 includes a frame 121, an adjusting cylinder 122, and an anti-sticking fixed roller 123 and a resistance roller 124 rotatably mounted inside the frame 121. The adjusting cylinder 122 is fixed to the top surface of the vertical frame 121 and its output end is fixedly connected to a bearing seat for engaging the rotation of the resistance roller 124. The surface of the anti-sticking fixed roller 123 is provided with an anti-sticking coating.

[0044] Specifically, driven by the regulating cylinder 122, the surfaces of the anti-sticking roller 123 and the resistance roller 124 come into contact with each other to provide a certain resistance to the movement of the conveyor belt, so as to prevent the conveyor belt from sticking due to tension relaxation between the tension positioning component 120 and the winding roller.

[0045] Working principle and usage process of this invention:

[0046] When using this tape winding device, the winding roller is first placed inside the main wheel 310 and the ear plate 320. The active drive of the drive cylinder 230 pushes the gripper rod 220 to deflect at the bottom of the machine base 210, and simultaneously drives the ear plate 320 to deflect on the surface of the main wheel 310, so that the ear plate 320 closes with the surface of the main wheel 310. Under the elastic recovery of the gripping belt 340 and the elastic abutment of the gripping belt 340, the gripping belt 340 is tightly attached to the surface of the winding roller. The ends of the ear plates 320 on both sides are interlocked, and the winding roller is clamped inside the wheel sleeve assembly 300. After passing one end of the tape between the anti-sticking fixed roller 123 and the resistance roller 124, it is guided and fixed to the surface of the winding roller.

[0047] During the winding process, the drive motor 110 drives the transmission wheel 211 and the synchronous shaft 410 to rotate. The transmission pulleys inside the transmission box 400 cause each transmission wheel 211 to rotate synchronously and rub against the surface of the wheel sleeve assembly 300, thus achieving the rotation of the wheel sleeve assembly 300. The contact between the lifting wheels 221 on the surface of the hanger 212 and the gripper 220 and the surface of the roller edge 350 is used to lift the wheel sleeve assembly 300 and the winding roll, ensuring the wheel sleeve assembly 300 is positioned on the machine base 210 and the gripper 220. The take-up roller rotates under the gripping of the 20. When the winding tension is large, slippage occurs between the take-up roller and the gripping belt 340, thereby avoiding the stretching deformation and breakage of the tape caused by the rigid transmission of the take-up roller. Tension positioning components 120 are arranged on the surface of the take-up frame 100 to guide the tape and provide constant tension at the take-up end, thus preventing the tape from sticking. After the take-up is completed, the gripping claw rod 220 is driven to deflect by the drive cylinder 230, which drives the ear plate 320 to deflect, thus releasing the completed take-up roller with one key.

[0048] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
