Description

Technical Field

[0001] This utility model relates to the technical field of reinforcing steel sheet processing equipment, and in particular to a quick material changing and receiving device for adhesive tape machine rolls. Background Technology

[0002] In the manufacturing fields of electronics and automobiles, reinforcing steel sheets are a key structural reinforcement component. They are often bonded to the main structure by applying special adhesive tape. This process is usually completed by a special adhesive tape application equipment. Its core is to feed the tape through an unwinding mechanism and to press the tape precisely onto the surface of the reinforcing steel sheet by a bonding mechanism. Most adhesive tape application machines in the current technology adopt a single roll feeding mode, that is, one machine is equipped with only one roll unwinding station.

[0003] However, this single-roll feeding mode has significant drawbacks. When a roll of tape is used up, the machine must be stopped for manual roll replacement. This process involves a series of tedious steps, including unloading the old roll, installing the new roll, pulling and straightening the tape, passing it through a complex guide, and initial positioning of the new tape. This not only leads to long downtime, severely restricting the overall efficiency and capacity of the production line, but also makes it difficult to ensure the stability of the tension and the accuracy of the initial position of the new tape during manual operation. This can easily introduce quality problems such as bonding position deviation and tape wrinkles, affecting product yield.

[0004] Therefore, with the increasing demands for continuity and reliability in automated production, developing a new type of adhesive application device that can achieve rapid material change without stopping the machine, ensure continuous and stable operation of the production process, and effectively improve the consistency of adhesive application quality has become an urgent technical problem to be solved in this field. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a quick material changing and receiving device for adhesive tape machine rolls, so as to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides a quick film changing and receiving device for an adhesive applicator, comprising: frame; The unwinding assembly includes a first unwinding unit and a second unwinding unit arranged side by side on the frame, for carrying working film and spare film respectively; A winding assembly, which is mounted on the frame, is used to pull and wind the backing paper of the film roll during operation; A receiving platform is disposed between the unwinding assembly and the rewinding assembly. The receiving platform has a bearing surface for supporting and positioning the backing paper end and the end of the spare film on the rewinding assembly during material change. The bonding assembly, which is disposed above the bearing surface, includes a driving member and a pressing member that is driven to rise and fall by the driving member. When the end of the backing paper and the end of the spare film roll are aligned on the bearing surface, the pressing member presses the bonding part covered with the substrate tape to make the bonding surface tightly bonded.

[0007] As a preferred technical solution of this utility model, the receiving platform includes a conveyor belt machine, which has a conveyor belt. The conveyor belt is stationary when changing materials to carry and position the backing paper and the end of the second film on the winding assembly, and is used to continuously transport the reinforcing steel sheet to be glued to the underside of the bonding assembly during the adhesive application operation.

[0008] As a preferred technical solution of this utility model, the bonding component includes a cylinder, and the movable rod end of the cylinder is connected to a pressure plate. When changing materials, the cylinder drives the pressure plate to press the bonding surfaces together. During the adhesive application operation, the cylinder drives the pressure plate to press the adhesive strip on the back paper of the adhesive roll to the corresponding position on the reinforcing steel sheet.

[0009] As a preferred embodiment of this utility model, the frame is provided with a guide roller assembly, which is used to guide and support the film roll so that it is transported smoothly along a preset path.

[0010] As a preferred embodiment of the present invention, the guide roller assembly includes at least two parallel guide rollers, which are located below the bonding assembly and above the receiving platform.

[0011] As a preferred embodiment of the present invention, the frame includes a mounting plate for mounting an unwinding assembly, a winding assembly, and a bonding assembly, and a bracket for mounting the mounting plate above the conveyor belt, one end of the bracket being fixedly connected to the conveyor belt machine.

[0012] As a preferred embodiment of the present invention, the first unwinding unit and the second unwinding unit include two unwinding reels rotatably mounted on the mounting plate, and a damping device connected to each of the unwinding reels. The winding assembly includes a driving device mounted on the mounting plate, and the output end of the driving device is connected to a winding reel.

[0013] As a preferred embodiment of this utility model, the front end of the unwinding reel forms a first positioning post with a stepped distribution. The first positioning post is plugged into and connected to a first limiting plate provided with a first positioning sleeve. The circumferential surface of the first positioning sleeve has a through first mounting hole, and the circumferential surface of the first positioning post has a through second mounting hole. A first connecting member is connected between the second mounting hole and the first mounting hole. The front end of the take-up reel forms a second positioning post with a stepped distribution. The second positioning post is plugged into and connected to a second limiting plate provided with a second positioning sleeve. The circumferential surface of the second positioning sleeve has a through third mounting hole, and the circumferential surface of the second positioning post has a fourth mounting hole. A second connecting member is connected between the fourth mounting hole and the third mounting hole.

[0014] The beneficial effects of this utility model are as follows: By setting up a double unwinding unit and a receiving platform, this utility model enables the equipment to prepare spare film rolls in advance while the main adhesive application operation is ongoing. When the working film roll is exhausted, the system can immediately switch to a new roll online since the spare film roll is already in place, without going through the time-consuming steps of traditional shutdown, disassembly, and feeding. This minimizes the material changeover time, greatly reduces equipment downtime, and directly improves the overall production efficiency. Secondly, the bonding components perform precise and reliable pressing on the bonding parts, ensuring the continuity strength and flatness of the new and old material strips. This mechanism avoids the risk of secondary breakage or deviation due to weak bonding. Therefore, not only is the material receiving speed fast, but the success rate is also high and the quality is stable, ensuring the continuity of adhesive application operations and product yield after material changeover. This further consolidates the results of efficiency improvement from the perspectives of quality and reliability. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0019] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

[0020] like Figure 1 and Figure 2 As shown, a quick material changing and receiving device for adhesive tape application machine includes: a frame; an unwinding assembly, which includes a first unwinding unit and a second unwinding unit arranged side by side on the frame for carrying a working film roll 25 and a spare film roll respectively; a rewinding assembly, which is arranged on the frame for pulling and rewinding the backing paper of the film roll during operation; a receiving platform, which is arranged between the unwinding assembly and the rewinding assembly, and the receiving platform has a bearing surface for supporting and positioning the end of the backing paper and the end of the spare film roll on the rewinding assembly during material changing; and a bonding assembly, which is arranged above the bearing surface, including a driving component and a pressing component that is driven to rise and fall by the driving component. When the end of the backing paper and the end of the spare film roll are aligned on the bearing surface, the pressing component presses the bonding area covered with the substrate tape to make the bonding surface tightly bonded. The above technical solution can solve the problems of long equipment downtime and low material feeding efficiency in traditional material changing processes. Specifically, its working principle is as follows: When the working film roll 25 is about to run out, the operator places the end of the spare film roll and the backing paper end on the receiving platform to align them, and covers the joint with substrate tape. At this time, the drive unit drives the pressing unit to press down and press the bonding part together. When using it, the operation steps include: first, pausing the equipment and aligning the ends of the new and old materials on the receiving platform; then, pasting the substrate tape; finally, starting the bonding unit to complete the pressing operation. Through the integrated receiving platform and bonding unit, fast and reliable film roll splicing is achieved, effectively reducing equipment downtime and improving production efficiency.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the receiving platform includes a conveyor belt 1, which has a conveyor belt 2. The conveyor belt 2 is stationary during material change to carry and position the backing paper and the end of the second film roll on the winding assembly, and is used to continuously transport the reinforcing steel sheet 3 to be glued to the underside of the bonding assembly during the adhesive application operation. The above technical solution solves the problems of complex equipment structure and large space occupation caused by the need for a separate material receiving station in traditional equipment. Specifically, the material receiving platform uses a conveyor belt 1 as the supporting foundation, and its conveyor belt 2 has a dual function: it remains stationary during material changing, providing a stable bearing and positioning surface for the ends of the backing paper and the second film roll; during normal adhesive application, it runs continuously, accurately conveying the reinforcing steel sheet 3 to the bonding station. This design achieves both material receiving and positioning and workpiece conveying functions through a single component, simplifying the equipment structure while ensuring the accuracy of material receiving and adhesive application.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the bonding assembly includes a cylinder 23, and the movable rod end of the cylinder 23 is connected to a pressure plate 24. When changing materials, the cylinder 23 drives the pressure plate 24 to press the bonding surfaces together. During the adhesive application operation, the cylinder 23 drives the pressure plate 24 to press the adhesive strip 26 on the back paper of the adhesive roll to the corresponding position on the reinforcing steel sheet 3. The above technical solution can solve the problem that traditional equipment needs to set up a material receiving and pressing mechanism and an adhesive application mechanism separately. Specifically, the bonding component achieves dual operation functions by driving the pressure plate 24 through the cylinder 23: when changing materials, the cylinder 23 drives the pressure plate 24 to press the adhesive tape bonding part of the substrate; when applying adhesive, the same cylinder 23 and pressure plate 24 press the adhesive strip 26 onto the reinforcing steel sheet 3. Two different pressing operations are achieved through a single actuator, which simplifies the equipment structure, reduces manufacturing costs, and ensures the uniformity and consistency of bonding quality.

[0023] like Figure 2 and Figure 4 As shown, in this embodiment, a guide roller assembly is provided on the frame, which is used to guide and support the film roll so that it is transported smoothly along a preset path. The above technical solution can solve the problems of film rolls easily deviating, wrinkling or uneven tension during transportation. Specifically, its working principle is to ensure that the film roll maintains a preset tension state and a stable running trajectory between the unwinding assembly, the receiving platform and the rewinding assembly by guiding and supporting the guide rollers. In use, the film roll passes around each guide roller in sequence to form a defined transportation path.

[0024] like Figure 3 and Figure 4 As shown, in this embodiment, the guide roller assembly includes at least two parallel guide rollers 22, which are located below the bonding assembly and above the receiving platform. The above-mentioned technical solution can solve the technical problem of film sagging or shifting during the critical stages of film splicing and adhesive application. Specifically, its working principle is that two guide rollers 22 form a stable triangular support area, ensuring that the film remains flat when passing through the splicing platform and the bonding assembly. During operation, the film passes between the two guide rollers 22, obtaining the necessary tension and positioning. Precise guidance control ensures the accuracy of the splicing position and the consistency of the adhesive application quality.

[0025] like Figure 1 and Figure 2 As shown, in this embodiment, the frame includes a mounting plate 5 for mounting the unwinding assembly, the winding assembly, and the bonding assembly, and a bracket 4 for mounting the mounting plate 5 above the conveyor belt 2, one end of the bracket 4 being fixedly connected to the conveyor belt machine 1. The above technical solution solves the problems of scattered installation of functional modules and difficulty in ensuring relative positional accuracy in traditional equipment. Specifically, its working principle is as follows: the bracket 4 firmly supports the mounting plate 5 above the conveyor belt 2, forming a suspended layout; the mounting plate 5 provides a unified installation reference for the unwinding assembly, the winding assembly, and the bonding assembly. The integrated frame design ensures the positional accuracy between the various actuators, improving the stability and reliability of the equipment operation.

[0026] like Figure 3 and Figure 4 As shown, in this embodiment, the first unwinding unit and the second unwinding unit include two unwinding reels 7 rotatably mounted on the mounting plate 5, and a damping device 6 connected to each unwinding reel 7. The winding assembly includes a driving device 14 mounted on the mounting plate 5, and the output end of the driving device 14 is connected to a winding reel 15. The above technical solution can solve the problems of inaccurate splicing and uneven adhesive application caused by tension fluctuations during film transport. Specifically, the unwinding unit provides constant rotational resistance to the unwinding reel 7 through the damping device 6, and the rewinding assembly provides active traction force to the rewinding reel 15 through the drive device 14. Its working principle is as follows: the damping device 6 maintains stable unwinding tension, and the drive device 14 maintains a constant rewinding speed. The two work together to ensure tension balance of the film throughout the transport process. The combination of active rewinding and passive unwinding achieves smooth film transport, ensuring the quality stability of splicing and adhesive application operations.

[0027] like Figure 4 As shown, in this embodiment, the front end of the unwinding reel 7 forms a first positioning post 8 with a stepped distribution. The first positioning post 8 is plugged into and connected to a first limiting plate 9 provided with a first positioning sleeve 10. The circumferential surface of the first positioning sleeve 10 is provided with a through first mounting hole 11. The circumferential surface of the first positioning post 8 is provided with a through second mounting hole 12. A first connector 13 is connected between the second mounting hole 12 and the first mounting hole 11. The front end of the take-up reel 15 forms a second positioning post 16 with a stepped distribution. The second positioning post 16 is plugged into and connected to a second limiting plate 17 provided with a second positioning sleeve 18. The circumferential surface of the second positioning sleeve 18 is provided with a through third mounting hole 19. The circumferential surface of the second positioning post 16 is provided with a fourth mounting hole 20. A second connector 21 is connected between the fourth mounting hole 20 and the third mounting hole 19. The above technical solution solves the problems of cumbersome operation and difficulty in guaranteeing positioning accuracy when changing material trays in traditional equipment. Specifically, the unwinding tray 7 and the rewinding tray 15 adopt a quick-clamping structure. Quick positioning is achieved through the insertion and removal of the first positioning pin 8 and the first positioning sleeve 10, and the second positioning pin 16 and the second positioning sleeve 18. Locking is then completed through the first connecting piece 13 and the second connecting piece 21. In use, the operator only needs to insert the positioning pin and install the connecting piece to fix the material tray. The precise cooperation between the positioning pin and the sleeve enables quick and accurate installation of the material tray, significantly improving the efficiency and accuracy of the material changing operation.
