Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, specifically to a sealing strip winding device. Background Technology

[0002] Edge banding is a material used to protect, decorate, and beautify the cross-section of furniture panels, allowing the furniture to display clear wood grain and vibrant colors. PVC edge banding is primarily composed of polyvinyl chloride, produced through processes such as mixing, calendering, and vacuum forming. Since the cross-sections of different types of furniture panels vary, the types and sizes of edge banding used will also differ. In the actual production process, the winding and packaging of different types and sizes of edge banding after printing and drying is a crucial step.

[0003] However, the current edge banding rewinding equipment has certain structural design flaws. Not only is the structure complex, but its functions are also fixed, resulting in poor applicability. It can only rewind edge banding strips of a certain size or type. When rewinding edge banding strips of multiple sizes or types is required, it is necessary to purchase or redesign edge banding rewinding equipment to suit the corresponding sizes or types, or to remove or replace the edge banding rewinding mechanism on the original equipment. Regardless of the method, this requires significant manpower and resources, necessitating the purchase of a large number of equipment or parts, and extensive and frequent experiments, trials, and debugging before it can be properly applied to the rewinding of edge banding strips of the corresponding size or type. Undoubtedly, all of these factors severely impact the production efficiency of edge banding strips and significantly increase their production costs. Meanwhile, the existing edge banding strip winding equipment is extremely convenient for loading and unloading. It generally requires workers to perform a series of operations such as loading, clamping, cutting, unloading, and discharging. This means that each machine must be operated by at least one worker throughout the entire process. This not only increases the labor intensity of workers, but also seriously affects the winding efficiency and quality of edge banding strips. Long-term manual operation also brings the risk of misoperation, which can lead to frequent equipment failures or product damage, seriously affecting the production efficiency and quality of edge banding strips and failing to meet the current demand for large-volume, high-frequency production of edge banding strips of various sizes or types.

[0004] In conclusion, it is necessary to further innovate existing technologies. Summary of the Invention

[0010] The initial state of the take-up reel is a clustered disc shape.

[0019] By adopting the above technical solution, this utility model has the following beneficial effects:

[0020] This utility model of edge banding strip winding equipment features a reasonable and compact structure, convenient operation, stable and reliable operation, and strong applicability. In particular, its innovative design of the repositioning winding mechanism allows for the installation of multiple inner core chucks of different types or sizes. When winding edge banding strips of a corresponding size or type is required, the electronic control device controls the repositioning drive motor to rotate the frame, rotating the inner core chuck of the corresponding size or type to a position above the winding worktable for fast and accurate winding. This, combined with the lifting drive device, lifting bracket, and positioning sensors, ensures that the corresponding inner core chuck is quickly and accurately positioned and installed on the winding worktable, preparing for subsequent edge banding strip winding. This structural design enables efficient winding of edge banding strips of different types or sizes on the same winding equipment, effectively solving the current problem of dealing with various edge banding strip sizes. The high costs associated with redesigning the edge banding winding mechanism, winding components, or replacing the entire edge banding winding equipment when winding edge banding strips of the same size or different types are a significant concern. However, by utilizing components and mechanisms such as electrical control devices, winding motors, shifting winding mechanisms, inner core chucks, edge banding strip transmission and traction mechanisms, edge banding strip cutting mechanisms, edge banding strip discharge mechanisms, and lateral movement mechanisms in a coordinated manner, this system can efficiently and cost-effectively wind edge banding strips of different types or sizes. Furthermore, the entire winding process is largely mechanized and automated, allowing one worker to maintain multiple machines simultaneously. This significantly improves edge banding winding quality and production efficiency while also significantly reducing production costs. It effectively meets the needs of mass production of edge banding strips of various sizes or types, making it suitable for widespread application.

[0021] The inner core chuck structure of this utility model is ingeniously designed. It works in conjunction with the winding and unwinding drive device, the edge strip transmission and traction mechanism, and corresponding position sensors to enable the inner core chuck to rise and fall precisely, and the winding wheel to quickly converge or expand. This allows the edge sealing strip to complete a series of actions such as clamping, winding, unwinding, and resetting in real time and efficiently, significantly improving the winding efficiency and quality of the edge sealing strip. At the same time, the entire inner core chuck is easy to disassemble and assemble, facilitating later replacement, repair, or maintenance.

[0022] This utility model achieves fully mechanized operation of edge banding strip transmission and traction feeding through an innovatively designed edge banding strip transmission and traction mechanism. It works in conjunction with an electrical control device, a lateral movement mechanism, and corresponding position sensors. Furthermore, the lateral movement mechanism works in conjunction with a repositioning and winding mechanism and an inner core chuck. First, the repositioning and winding mechanism selects the corresponding model of inner core chuck based on the type or size of the edge banding strip to be wound. Then, the lateral movement mechanism determines the lateral displacement distance based on the size of the selected inner core chuck, ensuring that the edge banding strip transmission and traction mechanism can accurately pull the edge banding strip to the periphery of the corresponding inner core chuck for clamping and feeding. This multi-mechanism collaborative feeding structure design enables fully mechanized and automated operation of edge banding strip traction feeding, ensuring precise timing and position of edge banding strip traction feeding, significantly improving the efficiency of edge banding strip traction feeding, and effectively avoiding the personal safety risks and equipment failure risks caused by excessive fatigue from manual operation.

[0023] This invention achieves fully mechanized edge banding shearing through an edge banding shearing mechanism. Its coordinated use with components such as the electrical control device, winding worktable, and winding and unwinding drive ensures precise timing and position for edge banding shearing. This fully mechanized automatic shearing removes excess edge banding after each roll of product is wound, improving shearing efficiency and effectively avoiding the fatigue issues caused by prolonged, frequent manual shearing operations. It also avoids personal safety risks and frequent equipment malfunctions due to excessive fatigue.

[0024] This utility model enables the rapid recycling of edge sealing strips through the edge sealing strip discharge mechanism. Its coordinated use with components such as the electronic control device, corresponding position sensor, inner core chuck, and winding and unwinding drive device ensures precise discharge timing and convenient and fast discharge, further improving the winding efficiency of edge sealing strips.

The upper housing 12 is fixed to the top center area of ​​the lower housing 11 and has an internal storage space. An upper inspection door 121 is located on one side of the upper part of the upper housing 12. A transparent observation window is also provided on the side of the upper housing 12. The winding worktable 112 is located directly below the upper housing 12.

[0040] The number of winding motors 2 and repositioning winding mechanisms 3 can be set as needed. In this embodiment, two sets of winding motors 2 and repositioning winding mechanisms 3 are symmetrically arranged.

[0041] Each set of take-up motors 2 is matched and installed inside the lower housing 11 and electrically connected to the electrical control device 4. It is located on the bottom side of the take-up worktable 112 and its power output end is connected to the take-up worktable 112 to drive the take-up worktable 112 to rotate as needed.

[0042] Each set of shifting and winding mechanisms 3 is matched and installed inside the upper casing 12 of the machine housing 1, including the frame 31, shifting drive motor 32, lifting drive device 33, lifting bracket 34, and winding and unwinding drive device 35.

[0043] The frame 31 is fixed inside the upper casing 12 of the housing 1; a rotating shaft 311 is vertically installed in the middle of the frame 31; the rotating shaft 311 is hinged to the frame 31 by a bearing, the upper end of the shaft extends upward toward the frame 31 and a first pulley 36 is fixedly installed at the extended end, and the lower end extends downward toward the frame 31 and a fixed bracket 312 is fixedly installed on the outer circumference; a cylinder sliding support rod is vertically installed on the fixed bracket 312.

Its power output end is equipped with a second pulley 321 and is connected to the first pulley 36 on the rotating shaft 311 of the frame 31 by the second pulley 321 and the belt 37. The shift drive motor 32 drives the rotating shaft 311 to rotate, thereby driving the fixed bracket 312 to rotate synchronously.

[0045] The lifting drive device 33 has multiple units evenly distributed around the fixed bracket 312 of the frame 31. In this embodiment, three lifting drive devices 33 are evenly distributed around the fixed bracket 312, and the three lifting drive devices 33 correspond to three inner core chucks 5 of large, medium, and small sizes, respectively, for winding edge banding strips of three types or sizes. Each lifting drive device 33 is electrically connected to the electronic control device 4, and a lifting bracket 34 is installed at the power output end. Both the lifting drive device 33 and the lifting bracket 34 rotate synchronously with the fixed bracket 312. In this embodiment, each lifting drive device 33 is a bidirectional lifting cylinder.

Its power output shaft passes through the shaft tube in the lower part of the lifting bracket 34 and extends downward therefrom. The extended end is detachably assembled and connected to the upper end of the inner core chuck 5. The fixing clamp is used to restrict the rotation of the power output shaft of the winding and unwinding drive device 35. Specifically, a rectangular groove is provided in the middle of the fixing clamp; the power output shaft of the winding and unwinding drive device 35 has symmetrical cross-sections on its opposite radial circumferential surfaces; the power output shaft of the winding and unwinding drive device 35 moves vertically through the rectangular groove in the middle of the fixing clamp and slides with the inner wall of the rectangular groove through the cross-sections on its opposite sides, so that the power output shaft of the winding and unwinding drive device 35 can only slide up and down within the rectangular groove and cannot rotate. A positioning sensor is also matched to one side of the winding and unwinding drive device 35. This positioning sensor is electrically connected to the electronic control device 4 and is used to position the inner core chuck 5 on the winding worktable 112. In this embodiment, a circular groove is provided at the center of the end of the power output shaft of the winding and unwinding drive device 35. In this embodiment, the winding and unwinding drive device 35 adopts an expansion block drive cylinder; the expansion block drive cylinder is connected to an external air source and an electronic control device 4 through a solenoid valve, and the end of its cylinder rod is connected to the inner core chuck 5 and a circular groove is provided at the center of the end.

[0047] The number of inner core chucks 5 corresponds to the number of lifting drive devices 33 on the transposition and rewinding mechanism 3. For example... Figure 5-10As shown, each inner core chuck 5 includes a mounting shaft 51, a stretching block 52, a sliding plate 53, a bearing assembly 54, a spring pin assembly 55, a winding wheel 56, and an edge sealing strip clamp 57.

[0048] The upper end of the mounting shaft 51 is detachably assembled and connected to the shaft tube at the lower part of the lifting bracket 34 of the repositioning and winding mechanism 3.

The top end of the connecting rod 522 and the power output shaft of the winding and unwinding drive device 35 can be connected by a bearing to realize that the power output shaft of the winding and unwinding drive device 35 does not rotate with the expansion block 52. In this embodiment, a polygonal prism 5221 is fixedly connected to the top of the connecting rod 522, and a spherical protrusion 5222 is matched and protruded at the center of the top of the polygonal prism 5221. Specifically, the spherical protrusion 5222 is matched and movably connected to the circular groove on the end face of the power output shaft of the winding and unwinding drive device 35, so that the expansion block 52 rotates around the circular groove on the end face of the power output shaft of the winding and unwinding drive device 35 through the spherical protrusion 5222. At the same time, the power output shaft of the winding and unwinding drive device 35 is also fixed by the fixing clip, which can completely ensure that the power output shaft of the winding and unwinding drive device 35 does not rotate with the expansion block 52. This method has a lower cost. The expansion block body 521 and the connecting rod 522 can be an integral structure; however, in this embodiment, the expansion block body 521 and the connecting rod 522 adopt a detachable separate structure; the expansion block body 21 has a connecting rod insertion hole from the top center inward, and a connecting rod fixing hole through to the connecting rod insertion hole is opened in the middle of a set of opposite sides; the lower end of the connecting rod 522 is inserted into the connecting rod insertion hole and locked and fixed to the expansion block body 521 by fasteners through the connecting rod fixing hole.

[0052] like Figure 10 As shown, the take-up reel 56 is fixedly installed on the bottom of the take-up reel mounting plate 541 of the bearing assembly 54. In this embodiment, the take-up reel 56 is composed of two separate semi-circular take-up blocks 561. The two semi-circular take-up blocks 561 are respectively matched and fixedly installed on the bottom of the take-up reel mounting plates 541 of a pair of bearing assemblies 54 and are connected to each other by a return spring. Specifically, the two semi-circular take-up blocks 561 are assembled and fixed to the bottom of the take-up reel mounting plate 541 through the take-up reel mounting holes 5412 on the take-up reel mounting plates 541 of the pair of bearing assemblies 54 with fasteners. In this embodiment, the two semi-circular take-up blocks 561 are also matched with a return spring mounting groove at their bottoms, and a return spring is matched and embedded in the return spring mounting groove. The return spring does not protrude outward from the return spring mounting groove, and its two ends are respectively fixedly connected to the return spring mounting groove at the bottom of the two semi-circular take-up blocks 561.

The operation panel is matched and installed on the outer wall of the upper casing 12 and is electrically connected to the PLC controller inside.

[0062] The working principle of this edge banding strip winding device is as follows:

[0063] Before winding up the edge banding strip, it is necessary to ensure that the upper bushing 512 of the mounting shaft 51 of each inner core chuck 5 is fixedly assembled with the corresponding lifting bracket 34 on the shifting and winding mechanism 3 through the mounting hole 5122 and fasteners, and that the connecting rod 522 of the expansion block 52 extending above the upper bushing 512 is in active contact with the circular groove at the end of the power output shaft of the winding and unloading drive device 35 through the spherical protrusion 5222 provided on its top.

[0064] After all the inner core chucks 5 are installed, according to the pre-determined type or size of the edge banding strip to be wound, the electronic control device 4 controls the shifting drive motor 32 of the shifting and winding mechanism 3 to start, thereby driving the fixed bracket 312 to rotate and rotate the corresponding inner core chuck 5 to be directly above the winding worktable 112. At this time, the positioning sensor detects the positioning position of the inner core chuck 5 on the winding worktable 112 in real time and simultaneously controls the winding motor 2 to start through the electronic control device 4, thereby driving the winding worktable 112 to rotate and realize the dynamic adjustment of the winding worktable 112. Once the electronic control device 4 receives the positioning position of the inner core chuck 5 on the winding worktable 112 transmitted back by the positioning sensor, the rotation continues. After the signal indicating that the position is in place is received, the winding motor 2 is stopped first, and then the lifting drive device 33 is started to bring the inner core chuck 5 to the designated position on the winding worktable 112 for positioning and installation. The winding wheel 56 is initially in a converged disc shape. When the edge banding strip of this size or type begins to be wound, the inner core chuck 5 is positioned on the winding worktable 112 by the lifting drive device 33 through the positioning pins 552 protruding from the bottom of a pair of semi-circular winding blocks 561. Afterwards, the electronic control device 4 controls the activation of the slide plate drive device of the lateral movement mechanism 9 to drive the lateral movement slide plate 91 to move laterally to the designated position, and then activates the edge banding strip transmission and traction. The guiding mechanism 6 pulls the edge sealing strip to the outer circumference of the take-up roller 56. The electrical control device 4 then controls the start of the take-up and unwinding drive device 35. The power output shaft of the take-up and unwinding drive device 35 pushes the connecting rod 522 downward and drives the expansion block 52 to move downward as a whole, so that the lower end of the expansion block body 521 is inserted into the transverse slot of the slide groove 531 of the slide plate 53 to avoid obstruction. Since the lower end of the expansion block body 521 is a sloping structure, during the process of the expansion block body 521 being inserted downward into the slide groove 531, the sloping surface of the lower part of the expansion block body 521 will contact the bearing body 544 of the bearing assembly 54 and push the bearing body 544 to slide horizontally along the upper and lower surfaces of the slide plate 53, thereby... The take-up roller mounting plates 541 of the pair of bearing assemblies 54 move backwards from each other in the horizontal direction. The take-up roller mounting plates 541 are fixedly assembled with the semi-circular take-up blocks 561 of the take-up roller 56. When the take-up roller mounting plates 541 of the pair of bearing assemblies 54 move backwards from each other in the horizontal direction, the pair of semi-circular take-up blocks 561 of the take-up roller 56 also move backwards from each other in the horizontal direction. Together with the edge banding clips 57, they clamp the edge banding strip to the outer circumference of the take-up roller 56 to complete the feeding. At this time, the return spring is in a stretched state. Then, the electronic control device 4 controls the edge banding strip transmission and traction mechanism 6 to start and return to the initial position.

[0065] Next, the winding motor 2 is restarted by the electronic control device 4 to drive the winding worktable 112 to rotate and the winding wheel 56 to rotate synchronously (at the same time, the expansion block 52 rotates around the circular groove on the end face of the power output shaft of the winding and unwinding drive device 35 through the spherical protrusion 5222 at the top of the connecting rod 522) to realize the edge sealing strip winding work.

[0066] After all the edge banding strips of the corresponding size or type have been wound up, the electronic control device 4 controls the winding and unwinding drive device 35 to start, so that its power output shaft disengages from the spherical protrusion 5222 on the top of the connecting rod 522 of the expansion block 52. At this time, a pair of semi-circular winding blocks 561 regroup under the tension of the return spring and completely disengage from the edge banding strip. Finally, the electronic control device 4 controls the lifting drive device 33 to lift the inner core chuck 5 to the initial position. This edge banding winding work is completed and the strip is unwound. Afterwards, the electronic control device 4 detects that the inner core chuck 5 has been lifted to the initial position through the corresponding position sensor, and controls the edge banding strip unloading mechanism 8 to push the edge banding strip winding product out of the winding worktable 112 to complete the unloading. Thus, the winding work of one roll of edge banding strip product is completed.

[0067] If it is necessary to change to another size or type of edge banding strip for winding, simply control the shift drive motor 32 of the shift winding mechanism 3 through the electronic control device 4 to drive the fixed bracket 312 to rotate, and rotate the corresponding inner core chuck 5 to the top of the winding worktable 112. Then, the winding can be carried out according to the aforementioned feeding, clamping, unloading and unloading operation process.

[0068] This utility model has a reasonable and compact structural design, stable and reliable operation, convenient operation and strong applicability. It can achieve the winding of different types or sizes of edge banding strips on the same winding machine, which not only significantly reduces the winding cost of edge banding strips, but also greatly improves the winding efficiency of edge banding strips, and can effectively meet the needs of mass production of edge banding strips of multiple sizes or types.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
