Description
Technical Field
[0001] This utility model relates to the field of lifting technology for plate feeding machines, and in particular to a lifting mechanism for a three-station adhesive paper feeding machine. Background Technology
[0002] In industries such as electronics manufacturing and film processing, three-station film feeding and linerboard placement machines are commonly used to automate film feeding, linerboard placement, and linerboard placement. The lifting mechanism, as a core component, must meet the requirements of precise positioning, stable operation, and multi-station coordination. Existing linerboard placement machine lifting mechanisms mostly employ a single transmission method (such as belt drive or ordinary screw drive), achieving lifting through a simple guide structure (such as a single guide rail). Their power transmission stability and displacement control accuracy are limited, making them unsuitable for high-precision film processing scenarios. Furthermore, the limit devices in traditional mechanisms are mostly mechanical contact switches, which are prone to positioning deviations due to wear over long-term use, and issues such as tray tilting and asynchronous lifting can easily occur during multi-station switching.
[0003] Furthermore, existing lifting mechanisms typically rely on a single linear guide rail or guide column for guidance. When carrying heavy film, lateral forces can easily cause the pallet to wobble, affecting the accuracy of the adhesive paper padding process. Some mechanisms, although using screw drives, lack dual guidance and redundant limit switches, which may lead to overtravel damage during frequent start-stop operations. Moreover, maintenance and disassembly are inconvenient, making it difficult to meet the continuous operation requirements of automated production lines. Therefore, a lifting mechanism for a three-station adhesive paper padding machine is urgently needed to solve these problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a lifting mechanism for a three-station adhesive tape feeding machine. Its advantages include: ensuring stable power transmission through helical gear drive; achieving precise displacement control through a screw and nut assembly; ensuring the verticality of the pallet lifting through a double-guided structure; and completing safety limit switches, thereby achieving precise and stable lifting of the film tray in the three-station adhesive tape feeding machine.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A lifting mechanism for a three-station adhesive tape feeding machine includes a side plate and further includes:
[0007] Mounting base, the mounting base is fixedly connected to one outer wall of the side plate, and a motor for providing power to the lifting mechanism is fixedly connected to one outer wall of the mounting base;
[0008] A threaded screw, wherein a threaded sleeve is threadedly connected to the outer circumference of the threaded screw, a mounting plate is fixedly connected to one side of the outer wall of the threaded sleeve, and a support plate is fixedly connected to one side of the mounting plate;
[0009] Transmission assembly for driving the rotation of the lead screw;
[0010] A guide component that ensures the stable lifting and lowering of the lifting assembly.
[0011] Through the above technical solution: the motor is fixed to the side plate by the mounting bracket, providing a power source for the entire lifting mechanism. When the motor starts, its output rotational power will be transmitted to the threaded screw through the subsequent transmission components, thereby realizing the lifting movement of the pallet.
[0012] Preferably, the transmission assembly includes a second helical gear fixedly connected to the output end of the motor, a first helical gear meshing with the outer circumferential wall of the second helical gear, the first helical gear fixedly connected to the outer circumferential wall of the threaded screw, a base plate fixedly connected to the bottom outer wall of the side plate, a first rotating seat fixedly connected to the top outer wall of the base plate, and the threaded screw fixedly connected to the first rotating seat.
[0013] The above technical solutions provide stable rotational support for the threaded screw, enabling it to rotate smoothly under the drive of the motor. Through the cooperation between the threaded screw and the threaded sleeve, precise displacement control is achieved, driving the pallet to rise and fall precisely.
[0014] Preferably, a U-shaped plate is fixedly connected to the top outer wall of the side plate, a horizontal plate is fixedly connected to the bottom end of the U-shaped plate, and the top of the threaded rod is rotatably connected to the horizontal plate.
[0015] The above technical solutions provide a stable support structure for the upper end of the threaded screw, ensuring that the threaded screw will not wobble or deviate during rotation.
[0016] Preferably, a groove is formed on one outer wall of the side plate, and one end of the support plate passes through the inside of the groove.
[0017] Through the above technical solution: the slide provides guidance for the lifting and lowering of the pallet, restricts the horizontal displacement of the pallet, and makes the pallet move only along the vertical direction of the slide.
[0018] Preferably, the guide assembly includes a guide post fixedly connected to the top outer wall of the base plate, the top end of the guide post being fixedly connected to one side outer wall of the horizontal plate, and a slide cylinder being sleeved on the circumferential outer wall of the guide post, the slide cylinder being fixedly connected to the mounting plate.
[0019] The above technical solutions can effectively limit the horizontal offset of the mounting plate and the tray, ensure the verticality of the tray lifting and lowering, and at the same time, the structure can also share the lateral force generated when the tray carries the film, prevent the tray from shaking due to lateral force, and ensure the accuracy of the adhesive paper padding process.
[0020] Preferably, a support rod is fixedly connected to the top outer wall of the base plate, and the other end of the support rod is fixedly connected to the cross plate.
[0021] The above technical solutions enhance the structural strength and stability of the entire lifting mechanism, providing a reliable installation foundation for components such as magnetic switches.

[0024] Preferably, a guide seat is fixedly connected to one outer wall of the side plate, and a guide groove is formed on one outer wall of the guide seat. A second rotating seat is fixedly connected to both outer walls of the support plate. A guide wheel is rotatably connected to both inner walls of the second rotating seat. A guide groove is formed on one side of the guide seat, and the guide wheel is in rolling connection with the guide groove.
[0025] Through the above technical solution: when the pallet is raised or lowered, the guide wheel rolls in the guide groove, which further restricts the torsion and sway of the pallet. It works in conjunction with the first guide structure composed of the guide column and the slide to form a double guide, which improves the stability and accuracy of the pallet raising and lowering, and ensures that the film pallet remains stable during the raising and lowering process.
[0026] The beneficial effects of this utility model are as follows: throughout the entire lifting process, the mechanism ensures the stability of power transmission through helical gear transmission, while achieving precise displacement control through the screw and nut pair (a transmission component composed of a threaded screw and a threaded sleeve), the double guide structure ensures the verticality of the pallet lifting, and the magnetic switch completes the safety limit, thereby realizing the precise and stable lifting of the film tray in the three-station adhesive paper feeding machine.

[0033] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0034] Reference Figures 1-5 A lifting mechanism for a three-station adhesive paper feeding machine includes a side plate 1, and further includes:
[0035] Mounting base 19 is fixedly connected to one side outer wall of side plate 1, and a motor 18 for providing power to the lifting mechanism is fixedly connected to one side outer wall of mounting base 19.
[0036] A threaded screw 10 has a threaded sleeve 17 threadedly connected to its outer circumference. A mounting plate 4 is fixedly connected to one side of the outer wall of the threaded sleeve 17, and a support plate 16 is fixedly connected to one side of the mounting plate 4.
[0037] Transmission assembly for driving the screw 10 to rotate;
[0038] The guide component ensures stable lifting of the lifting assembly. The motor 18 is fixed to the side plate 1 via the mounting base 19, providing a power source for the entire lifting mechanism. When the motor 18 starts, its output rotational power will be transmitted to the threaded screw 10 through the subsequent transmission component, thereby realizing the lifting movement of the pallet 16.
[0039] To achieve precise displacement control, thereby enabling the pallet 16 to rise and fall accurately, refer to... Figures 1-4The transmission assembly includes a second helical gear 11 fixedly connected to the output end of the motor 18. A first helical gear 9 meshes with the outer circumferential wall of the second helical gear 11. The first helical gear 9 is fixedly connected to the outer circumferential wall of the threaded screw 10. A base plate 6 is fixedly connected to the bottom outer wall of the side plate 1. A first rotating seat 8 is fixedly connected to the top outer wall of the base plate 6. The threaded screw 10 is fixedly connected to the first rotating seat 8. In the transmission assembly, the second helical gear 11 fixed at the output end of the motor 18 meshes with the first helical gear 9 on the outer circumferential wall of the threaded screw 10. Compared with ordinary gear transmission, helical gear transmission can withstand greater loads, and the transmission process is smooth with low noise, which can effectively ensure the stability of power transmission. The threaded screw 10 is fixed to the base plate 6 through the first rotating seat 8, which can provide stable rotational support for the threaded screw 10, so that the threaded screw 10 can rotate smoothly under the drive of the motor 18. Thus, through the cooperation of the threaded screw 10 and the threaded sleeve 17, precise displacement control is achieved, driving the pallet 16 to rise and fall precisely.
[0040] To further improve the stability and accuracy of the transmission, refer to Figure 1 A U-shaped plate 15 is fixedly connected to the top outer wall of the side plate 1, and a horizontal plate 5 is fixedly connected to the bottom end of the U-shaped plate 15. The top of the threaded rod 10 is rotatably connected to the horizontal plate 5. By rotatably connecting the top of the threaded rod 10 to the horizontal plate 5, a stable support structure can be provided for the upper end of the threaded rod 10, ensuring that the threaded rod 10 will not shake or deviate during rotation.
[0041] To ensure the stability and accuracy of the lifting process of pallet 16, refer to Figures 1-2 A groove 2 is provided on one outer wall of the side plate 1. One end of the support plate 16 passes through the inside of the groove 2. The groove 2 provides a guide for the lifting and lowering of the support plate 16, restricts the horizontal displacement of the support plate 16, and makes the support plate 16 only move in the vertical direction of the groove 2.
[0042] To prevent the pallet 16 from wobbling due to lateral forces and to ensure the accuracy of the adhesive tape lining process, refer to... Figures 1-4 The guiding assembly includes a guide post 7 fixedly connected to the top outer wall of the base plate 6. The top end of the guide post 7 is fixedly connected to the outer wall of one side of the horizontal plate 5. A slide cylinder 3 is sleeved on the outer circumference of the guide post 7. The slide cylinder 3 is fixedly connected to the mounting plate 4. When the mounting plate 4 drives the tray 16 to rise and fall, the slide cylinder 3 slides on the outer wall of the guide post 7, which plays the first guiding role. It can effectively limit the horizontal displacement of the mounting plate 4 and the tray 16, and ensure the verticality of the tray 16. At the same time, this structure can also share the lateral force generated when the tray 16 carries the film, and prevent the tray 16 from shaking due to the lateral force, thus ensuring the accuracy of the adhesive paper padding process.
[0043] In order to provide auxiliary support for components such as guide column 7 and improve the overall rigidity of the mechanism, refer to Figure 1A support rod 13 is fixedly connected to the top outer wall of the base plate 6. The other end of the support rod 13 is fixedly connected to the horizontal plate 5, which enhances the structural strength and stability of the entire lifting mechanism and provides a reliable installation foundation for components such as the magnetic switch 12.
[0044] To effectively prevent damage to the mechanism due to overtravel and to ensure the safety and reliability of equipment operation, refer to Figure 1 A magnetic switch 12 is fixedly connected to one side of the outer wall of the support rod 13 to prevent damage to the mechanism due to overtravel. There are two magnetic switches 12. When the pallet 16 is raised or lowered to the limit position, the magnetic switch 12 is triggered and sends an electrical signal to the control system, causing the motor 18 to be de-energized and stop, effectively preventing the mechanism from being damaged due to overtravel and ensuring the safety and reliability of the equipment operation.
[0045] To improve the smoothness and accuracy of the lifting of pallet 16 and ensure the stability of the film pallet during lifting, refer to... Figures 4-5 A guide seat 20 is fixedly connected to one outer wall of the side plate 1. A guide groove 23 is provided on one outer wall of the guide seat 20. A second rotating seat 21 is fixedly connected to both outer walls of the pallet 16. A guide wheel 22 is rotatably connected to both inner walls of the second rotating seat 21. A guide groove 23 is provided on one side of the guide seat 20. The guide wheel 22 is tumbled in the guide groove 23. When the pallet 16 is raised or lowered, the guide wheel 22 rolls in the guide groove 23, further restricting the twisting and shaking of the pallet 16. It cooperates with the first guide structure composed of the guide column 7 and the slide cylinder 3 to form a double guide, which improves the stability and accuracy of the pallet 16 raising and lowering, and ensures that the film tray remains stable during the raising and lowering process.
[0046] Working principle: When the motor 18 is powered on and started, its output shaft drives the second helical gear 11 to rotate clockwise or counterclockwise. Since the second helical gear 11 and the first helical gear 9 are in a perpendicular meshing state, the two transmit the rotational power of the motor 18 to the threaded screw 10 through the meshing of the tooth profiles, causing it to rotate. When the threaded screw 10 rotates, the threaded sleeve 17 connected to its outer wall thread cannot rotate with the threaded screw 10 due to the limitation of the mounting plate 4, thus converting the rotational motion into a vertical linear motion. At this time, the support plate 16 is driven by the mounting plate 4, and one end of it passes through the preset slide groove 2 of the side plate 1 and rises and falls along the vertical trajectory of the slide groove 2.
[0047] To ensure the smooth movement of the pallet 16 during this process, the guide assembly plays a dual role. Two guide posts 7 are vertically fixed between the base plate 6 and the cross plate 5. The slide cylinder 3 is sleeved on the guide posts 7 and welded to the mounting plate 4. When the mounting plate 4 is raised or lowered, the slide cylinder 3 slides on the outer wall of the guide posts 7 to limit horizontal deviation. At the same time, the second rotating seats 21 on both sides of the pallet 16 are respectively equipped with guide wheels 22, and the guide wheels 22 are embedded in the guide grooves 23 of the guide seats 20 and roll. The contact between the rollers and the groove walls further suppresses the twisting or shaking of the pallet 16.
[0048] When the pallet 16 is raised or lowered to its limit position, the magnetic switch 12 installed on the support rod 13 is triggered. The reed switch inside the magnetic switch 12 conducts when it approaches a magnetic object (such as a magnet installed on the pallet 16), sending an electrical signal to the control system. The motor 18 is then de-energized and stops rotating to prevent the threaded screw 10 and threaded sleeve 17 from colliding with the horizontal plate 5 or the bottom plate 6 due to overtravel. Throughout the process, the stability of power transmission is ensured by helical gear transmission, while precise displacement control is achieved by the screw and nut pair (the transmission component consisting of the threaded screw 10 and the threaded sleeve 17). The double guide structure ensures the verticality of the pallet 16's raising and lowering. The magnetic switch 12 completes the safety limit, thereby achieving precise and stable raising and lowering of the film tray in the three-station adhesive paper feeding machine.
[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
