Description

Technical Field

[0001] This utility model relates to the field of laminating machine technology, and in particular to a multi-adhesive strip guide mechanism for laminating machines. Background Technology

[0002] In the industrial production of rolled adhesive products, in order for the product to be bonded to a predetermined position, a laminating machine is needed to complete the composite process of the roll material and the adhesive material. One existing type of roll material product involves attaching adhesive strips to at least one preset position on both sides and in the middle of the roll material to form a multi-layer composite structure. This process is the core link to ensure the performance of rolled adhesive products, and the laminating machine is the key equipment to realize this process.

[0003] In existing technologies, some laminating machines already possess the basic function of simultaneously attaching multiple adhesive strips to roll materials and have guide components for simultaneously positioning and guiding multiple adhesive strips. However, due to the significant differences in the required width specifications of adhesive strips and their attachment positions on the roll material for different types of rolled adhesive products, the guide components and positioning structures of traditional laminating machines are mostly fixed designs. This makes it impossible to adjust the guide channel size according to the adhesive strip width or quickly switch positioning parameters for different attachment positions. When producing products of different specifications, a considerable downtime is required for disassembly and mechanical adjustments, or for lengthy fine-tuning. This cumbersome and time-consuming process not only increases the cost of production changeovers but also easily leads to further reductions in adhesive strip attachment accuracy due to manual adjustment errors, making it difficult for the equipment to meet the flexible production needs of multiple varieties and small batches. Therefore, it is necessary to propose an improved technical solution to address these problems. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0005] A multi-adhesive strip guide mechanism for a laminating machine includes a fixed plate, a clamping strip screwed to the lower end of the fixed plate, and an adhesive strip correction plate clamped between the fixed plate and the clamping strip. The front end of the adhesive strip correction plate has multiple correction parts protruding from the fixed plate and the clamping strip, which are used to constrain the two sides of the adhesive strip. Connecting shafts are also provided on both sides of the fixed plate, and fixed seats are connected to the connecting shafts. The fixed plate is fixed by the fixed seats.

[0006] Preferably, a first raised portion is formed at the rear position of the lower end of the fixing plate, and the rubber strip correction plate abuts against the front of the first raised portion.

[0007] Preferably, two second raised parts are provided at the lower end of the fixing plate in front of the first raised part. The thickness of the second raised parts is less than the thickness of the first raised part, and the thickness of the second raised parts is less than the thickness of the rubber strip correction plate. The rubber strip correction plate abuts between the two second raised parts.

[0008] Preferably, the clamping strip abuts against the first raised part, and both ends of the clamping strip are fixed by screws at the position of the second raised part.

[0009] Preferably, the front side of the upper end of the fixing plate is provided with an inclined surface, which is connected and matched with the correction part.

[0010] Preferably, the rear side of the fixing plate is provided with an arc surface, the connecting shaft is in contact with the rear side of the fixing plate through the arc surface, and the connecting shaft is provided with multiple connecting holes, and the connecting shaft is fixedly connected to the rear side of the fixing plate through the connecting holes.

[0011] Preferably, one end of the fixing seat is provided with a fixing hole for mating with the connecting shaft, and the fixing seat is also provided with a threaded hole that is normally mated with the fixing hole. The fixing seat is threadedly connected to a tightening knob through the threaded hole, the connecting shaft passes through the fixing hole, and the connecting shaft and the fixing seat are fixedly engaged by tightening the tightening knob.

[0012] Preferably, one end of the connecting shaft has a portion extending beyond the fixed seat, and a handle is normally connected to the portion of the connecting shaft extending beyond the fixed seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The independent constraint design of multiple correction points at the front end of the adhesive strip correction plate allows for precise guidance of multiple adhesive strips simultaneously, preventing misalignment caused by strip deviation, improving adhesive strip adhesion accuracy, and ensuring the functional reliability and appearance consistency of the rolled adhesive products. Furthermore, the fixed plate and clamping strip utilize a detachable clamping structure connected by screws. When adapting to adhesive strips of different widths, only loosening the screws to replace the correction plate with one of the corresponding correction point size, or fine-tuning the correction plate position, eliminates the need for disassembly and mechanical adjustments, significantly shortening changeover time and reducing manual adjustment errors. In addition, the overall mechanism achieves quick installation and fixation via a fixed base and connecting shaft, adapting to the workstation requirements of different laminating machine models, further enhancing the equipment's flexible production capabilities, reducing changeover costs for enterprises, and contributing to improved quality and efficiency in the production of rolled adhesive products.

[0017] The reference numerals and names in the figure are as follows: Fixed plate 10, first raised part 11, second raised part 12, inclined surface 13, arc surface 14, pressing strip 20, rubber strip correction plate 30, correction part 31, connecting shaft 40, connecting hole 41, handle 42, fixed seat 50, fixed hole 51, threaded hole 52, tightening knob 53. Detailed Implementation

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Please see Figure 1-4In this embodiment of the present invention, a multi-adhesive strip guiding mechanism for a laminating machine includes a fixed plate 10, a clamping strip 20 screwed to the lower end of the fixed plate 10, and an adhesive strip correction plate 30 clamped between the fixed plate 10 and the clamping strip 20. The front end of the adhesive strip correction plate 30 has multiple correction portions 31 protruding from the fixed plate 10 and the clamping strip 20. The correction portions 31 are used to constrain the two sides of the adhesive strip. Connecting shafts 40 are also provided on both sides of the fixed plate 10. The connecting shafts 40 are connected to fixing seats 50, and the fixed plate 10 is fixed by the fixing seats 50. This laminating machine uses a multi-adhesive strip guiding mechanism with a modular structure design to achieve precise guidance and stable constraint of multiple adhesive strips. The mechanism, with the cooperation of a fixed base 50 and a connecting shaft 40, securely installs a fixed plate 10 at the corresponding station of the laminating machine, ensuring the overall structure remains stable during adhesive strip transport. Subsequently, an adhesive strip correction plate 30 is clamped and fixed between the fixed plate 10 and the pressing strip 20, with the two connected by screws to form a reliable clamping mechanism. This prevents displacement of the adhesive strip correction plate 30 during operation and allows adjustment of its installation angle or position by loosening the screws. When the adhesive strip enters the laminating machine's transport path, multiple correction parts 31 exposed at the front end of the adhesive strip correction plate 30 correspond to each adhesive strip. Each correction part 31 provides physical constraint to both sides of a single adhesive strip, limiting lateral deviation in real time as the adhesive strip is transported towards the roll lamination direction. This guides the adhesive strip to move precisely along a preset path, ultimately working with the laminating machine's lamination mechanism to accurately laminate the adhesive strip to the designated position on the roll.

[0020] Through the above technical solution, the guiding mechanism effectively solves the problems of poor adaptability, cumbersome adjustment, and insufficient positioning accuracy in the multi-adhesive strip guiding of traditional laminating machines. Specifically, through the independent constraint design of multiple correction parts 31 at the front end of the adhesive strip correction plate 30, multiple adhesive strips can be precisely guided simultaneously, avoiding misalignment caused by adhesive strip offset, improving adhesive strip adhesion accuracy, and ensuring the functional reliability and appearance consistency of the wound adhesive products. Moreover, the fixing plate 10 and the clamping strip 20 adopt a detachable clamping structure with screw connection. When it is necessary to adapt to adhesive strips of different widths, it is only necessary to loosen the screws and replace the adhesive strip correction plate 30 of the corresponding correction part 31 size, or finely adjust the position of the correction plate, without disassembling the equipment for mechanical adjustment, significantly shortening the changeover time and reducing manual adjustment errors. In addition, the overall mechanism can be quickly installed and fixed through the fixing seat 50 and the connecting shaft 40, adapting to the workstation requirements of different models of laminating machines, further improving the flexible production capacity of the equipment, reducing the production changeover cost of enterprises, and helping to improve the quality and efficiency of wound adhesive product production.

[0021] Please see Figure 4Based on the above technical solution, it is further proposed that a first raised portion 11 is formed at the rear position of the lower end of the fixing plate 10, and the adhesive strip correction plate 30 abuts against the front of the first raised portion 11. Two second raised portions 12 are provided at the lower end of the fixing plate 10 in front of the first raised portion 11. The thickness of the second raised portion 12 is less than the thickness of the first raised portion 11, and the thickness of the second raised portion 12 is less than the thickness of the adhesive strip correction plate 30. The adhesive strip correction plate 30 abuts between the two second raised portions 12. The first raised portion 11 at the rear of the lower end of the fixing plate 10 and the two second raised portions 12 at the front form a stepped support structure. On the one hand, the first raised portion 11 and the second raised portion 12 form a reliable abutment limit on the rear end and left and right sides of the rubber strip correction plate 30, which can ensure the accuracy of the installation position of the rubber strip correction plate 30. On the other hand, since the thickness of the second raised portion 12 is less than the thickness of the rubber strip correction plate 30, there is not only enough space between the fixing plate 10 and the pressing strip 20 to accommodate the rubber strip correction plate 30, but also the pressing strip 20 can apply a certain degree of pressing force to the rubber strip correction plate 30 after it is fixed, so as to prevent the rubber strip correction plate 30 from loosening and affecting the processing efficiency.

[0022] Please see Figure 2 and Figure 4 The clamping strip 20 abuts against the front of the first raised part 11, and the two ends of the clamping strip 20 are fixed by screws at the position of the second raised part 12; so that the clamping strip 20 can be initially positioned by the first raised part 11.

[0023] Please see Figure 2-3 An inclined surface 13 is provided on the front side of the upper end of the fixing plate 10, and the inclined surface 13 is connected and cooperates with the correction part 31. A smooth transition channel is formed before the adhesive strip enters the correction part 31, which effectively avoids the jamming and scratching problems caused by the right angle of the edge of the fixing plate 10 in the early stage of adhesive strip delivery, reduces the risk of adhesive strip damage, and guides the adhesive strip to enter the constraint range of the correction part 31 more smoothly, further improving the positional accuracy of the adhesive strip before it is attached.

[0024] Please see Figure 4 Based on the above technical solution, it is further proposed that the rear side of the fixing plate 10 is provided with an arc surface 14, and the connecting shaft 40 is connected to the rear side of the fixing plate 10 through the arc surface 14. The connecting shaft 40 is provided with multiple connecting holes 41, and the connecting shaft 40 is fixedly connected to the rear side of the fixing plate 10 through the connecting holes 41. The design of the arc surface 14 on the rear side of the fixing plate 10 makes the connecting shaft 40 and the fixing plate 10 form a smooth transition when they are connected. This avoids the stress concentration problem caused by right angle connection, improves the stability and service life of the connection structure, and the guiding effect of the arc surface 14 makes it easy for the connecting shaft 40 to quickly find the connection position during installation, reducing the assembly difficulty.

[0025] Please see Figure 2-4 One end of the fixed base 50 is provided with a fixing hole 51 for engaging the connecting shaft 40, and the fixed base 50 is also provided with a threaded hole 52 that is normally engaged with the fixing hole 51. The fixed base 50 is threadedly connected to a tightening knob 53 through the threaded hole 52. The connecting shaft 40 passes through the fixing hole 51, and the connecting shaft 40 and the fixed base 50 are fixedly engaged by tightening the tightening knob 53. The fixed base 50 engages with the connecting shaft 40 through the fixing hole 51 with the threaded hole 52, and can be quickly locked and unlocked by the tightening knob 53. Compared with the traditional disassembly-type mechanical adjustment, the operator only needs to rotate the tightening knob 53 to fix or loosen the connecting shaft 40 and the fixed base 50. When it is necessary to adjust the angle of the fixing plate 10 to adapt to different adhesive strip application requirements, there is no need to stop the machine to disassemble the equipment, which significantly shortens the adjustment time and reduces the intensity of manual operation.

[0026] Please see Figure 2-4 One end of the connecting shaft 40 has a portion extending beyond the fixed seat 50, and a handle 42 is normally connected to the portion of the connecting shaft 40 extending beyond the fixed seat 50. The handle 42 provides a convenient force application point for the operator to adjust the position of the connecting shaft 40, avoiding the inconvenience caused by direct contact with the connecting shaft 40. The lever action of the handle 42 also makes the rotation or translation adjustment of the connecting shaft 40 easier. Especially when it is necessary to fine-tune the angle of the fixed plate 10 to optimize the guiding accuracy of the rubber strip, the handle 42 can help the operator achieve more precise micro-adjustments.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
