Description

Technical Field

[0001] This utility model relates to the field of paper bonding gauge technology, specifically to an adjustable paper bonding gauge. Background Technology

[0002] Paper products are widely used in daily life, possessing excellent environmental characteristics such as reusability and lightweight. During the paper product manufacturing process, individual sheets of paper are glued together using adhesives in a top-to-bottom arrangement to increase thickness and strength, based on load-bearing and texture requirements. After drying, the glued paper enters the next process: die-cutting. The die-cutting process uses one side of the glued paper as a reference positioning edge for cutting the paper product sample. With this positioning edge as a reference, the die-cutting die can accurately cut the required paper product sample according to the printed patterns, text, and designs on the paper surface. Therefore, a guide is used in the glued process to regulate the relative positions of the upper and lower sheets during glued bonding. The aligned edge of the upper and lower sheets becomes the reference edge for the next die-cutting process.

[0003] During the paper lamination process, the reference edges of the laminated paper can be aligned with the top and bottom sheets, or the top sheet can be slightly recessed than the bottom sheet. Currently, when handling the requirement of the top sheet being slightly recessed, operators attach an adhesive block at a suitable position on the working surface of the guide rail to prevent the top sheet from being recessed. Specifically, when the guide rail fixes the positions of the top and bottom sheets, the top sheet is removed, leaving the bottom sheet in place, and the adhesive block is attached to the contact point between the top sheet and the guide rail. The bottom sheet remains in contact with the guide rail's working surface without the adhesive block. With the adhesive block in place, the top sheet is positioned at a distance from the guide rail's working surface to complete the lamination process with the bottom sheet. This results in the top sheet being recessed compared to the bottom sheet after lamination.

[0004] However, with this existing method, the adhesive blocks are prone to detaching during high-speed operation. Furthermore, once the adhesive block is applied, its thickness is fixed until it detaches and needs replacement; the thickness cannot be changed during use, which means the paper feed retraction distance cannot be adjusted. When changes in the thickness of the upper and lower paper require a change in the paper feed retraction distance, the current method of applying one adhesive block necessitates stopping the machine and reapplying a new one. Too much downtime leads to a decrease in production efficiency.

[0005] Therefore, the existing paper bonding guide needs further improvement. Utility Model Content

[0028] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0029] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0030] It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0031] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Example 1, see Figure 1-3An adjustable paper bonding guide includes a base 1, a guide body 2 on the base 1, a lower guide plate 21 on the base 1, a vertical connecting seat 22 on the outer side of the lower guide plate 21, an upper guide plate 3 movably mounted on the lower guide plate 21, and a lateral adjustment mechanism 4 between the vertical connecting seat 22 and the upper guide plate 3 that can drive the upper guide plate 3 to move laterally.

[0033] In one embodiment of the lower stop plate 21 and vertical connecting seat 22 described in this utility model, the lower stop plate 21 and the vertical connecting seat 2 are integrally formed; the lower stop plate 21 and the vertical connecting seat 22 form an L-shaped stop body 2.

[0034] In one embodiment of the lower baffle plate 21 and the vertical connecting seat 22 described in this utility model, the lower baffle plate 21 and the vertical connecting seat 22 can be set separately and connected by bolts.

[0035] This invention utilizes a lateral adjustment mechanism 4 to quickly adjust the relative positions of the upper baffle plate 3 and the lower baffle plate 21, thereby creating a staggered, uneven stepped working surface. When the upper and lower papers converge within the adjustable baffle and are positioned correctly, the lower paper rests against the working surface of the baffle plate 21, while the upper paper rests against the working surface of the upper baffle plate 3. This causes the upper paper 200 to recede a predetermined distance relative to the lower paper 100. After bonding, the coexisting lower edges of the upper and lower papers create a positional difference, thus fulfilling the process requirements.

[0036] When the required paper retraction distance needs to be changed according to the process, operators do not need to stop the machine to replace any physical stops or adhesive blocks. Simply operating the lateral adjustment mechanism 4 allows for quick and easy adjustment of the upper guide plate 3 to the new desired position. This significantly reduces or even eliminates the downtime required for adjusting the paper retraction distance, effectively improving production line efficiency. It avoids the drawbacks of existing technologies that require stopping the machine to adjust the relative position of the upper guide plate 3 and lower guide plate 21 by replacing adhesive blocks of different thicknesses. Simultaneously, it effectively eliminates the risk of adhesive block detachment, ensuring stable operation.

[0037] In this invention, the fixed lower guide plate 21 ensures the absolute stability of the paper positioning reference edge. The position of the upper guide plate 3 is set and locked by the adjustment mechanism 4, ensuring stability and reliability. This effectively guarantees the consistency of the paper positioning reference points, thereby ensuring the accuracy of the combined reference edge formed after bonding and the reference edge required for subsequent die-cutting processes.

[0038] This new utility model allows for stepless or step-by-step precise setting of the required paper feed retraction distance, enabling rapid adjustments without stopping the machine to adapt to different process requirements and significantly improving production efficiency. The adjustment method is simple and intuitive, making it easy for operators to master.

[0039] In a first embodiment of the lateral adjustment mechanism 4 of this utility model, the lateral adjustment mechanism 4 includes an adjustment seat 41 disposed within the outer end face of the upper baffle plate 3. A receiving groove 42 is provided within the upper baffle plate 3 outside the adjustment seat 41, and a first pressing spring 43 is disposed within the receiving groove 42. The first pressing spring 43 is responsible for pushing the upper baffle plate 3 forward during adjustment. A lateral through hole 44 is provided at a corresponding position on the vertical connecting seat 22 and the adjustment seat 41, and an adjustment bolt 45 is disposed within the lateral through hole 44. The adjustment bolt 45 is screwed into the adjustment seat 41. In this embodiment, the lateral adjustment mechanism 4 achieves precise adjustment of the position of the upper baffle plate 3 by means of the threaded engagement between the adjustment bolt 45 and the adjustment seat 41, and by the rotation of the bolt under the action of the first pressing spring 43, which drives the adjustment seat 41 to move laterally. Operators can easily adjust the horizontal position of the upper baffle plate 3 by simply rotating the adjustment bolt 45, avoiding complex disassembly and installation processes and improving work efficiency.

[0040] The threaded connection between the adjusting bolt 45 and the adjusting seat 41 has good self-locking properties, ensuring that the position is stable after adjustment and is not easily displaced by equipment vibration or external force, thus improving machining accuracy.

[0041] In a second embodiment of the lateral adjustment mechanism 4 of this utility model, the lateral adjustment mechanism 4 includes an adjustment seat 41 disposed within the outer end face of the upper stop plate 3. A lead screw sleeve is provided within the adjustment seat 41. A lateral through hole 44 is provided at a corresponding position on the vertical connecting seat 22 and the adjustment seat 41. An adjustment lead screw is disposed within the lateral through hole 44, and the adjustment lead screw is screwed into the lead screw sleeve. In this embodiment, the lead screw sleeve engages with the adjustment lead screw via a thread. Rotating the adjustment lead screw can drive the upper stop plate 3 to move horizontally, achieving precise adjustment. The lead screw transmission mechanism has high transmission accuracy, enabling micron-level adjustments, and is suitable for applications with strict positioning requirements. The threaded engagement has self-locking properties, maintaining a stable position without the need for additional locking devices after adjustment, preventing displacement due to vibration during processing. In this embodiment, the adjustment lead screw can also be driven by a motor to achieve automatic adjustment.

[0042] In this invention, scale markings can also be added to the adjusting bolt 45 or the adjusting seat 41 to make it easier for operators to intuitively grasp the adjustment amount and improve the adjustment accuracy.

[0043] In this invention, a guide groove 5 is provided on the lower stop plate 21, and a guide block 6 is provided on the upper stop plate 3 at a corresponding position to the guide groove 5. The guide block 6 is movably disposed within the guide groove 5. Through the cooperation between the guide block 6 and the guide groove 5, the movement of the upper stop plate 3 is made more stable.

[0044] In this utility model, a mounting screw hole 7 is provided on the upper surface of the base 1, and a connecting hole 8 is provided on the lower baffle plate 21 at a position corresponding to the mounting screw hole 7. A connecting bolt 9 is provided in the connecting hole 8 and the mounting screw hole 7.

[0045] Example 2, see Figure 4-9 Unlike the embodiment, in addition to having the main structure of embodiment 1, this utility model has a receiving groove 10 in the upper end surface of the base 1, and the lower baffle plate 21 is movably disposed in the receiving groove 10. A height adjustment mechanism 11 that can drive the lower baffle plate 21 to move up and down is provided between the lower baffle plate 21 and the base 1. The height adjustment mechanism 11 includes an assembly groove 111 disposed in the base 1, a driving long gear 112 disposed in the assembly groove 111, an adjustment hole 113 disposed on the outer side of the base 1, the outer end of the driving long gear 112 disposed in the adjustment hole 113, an adjustment inner hole 114 disposed in the outer end of the driving long gear 112, a transmission rack 115 disposed at the corresponding position of the lower baffle plate 21 and the driving long gear 112, the transmission rack 115 meshing with the driving long gear 112, and a locking mechanism 12 disposed between the driving long gear 112 and the base 1. In this invention, the height of the lower baffle plate relative to the base can be adjusted via a height adjustment mechanism, thus making it suitable for bonding papers of different thicknesses. During adjustment, an external tool can be inserted into the adjustment hole 114 to drive the drive gear 112 to rotate, thereby driving the transmission rack 115 to rise and fall. After adjustment, the adjustment is locked by the locking mechanism 12.

[0046] In this invention, a rotating scale can be added to the outer end of the drive gear 112, or a height scale can be added next to the lower gauge plate 21 to facilitate intuitive reading of the adjustment amount.

[0047] Alternatively, a handwheel or knob structure can be provided inside the outer end of the drive gear 112 to replace the adjustment inner hole 114, making adjustment more convenient and faster.

[0048] This invention can also be equipped with a servo motor drive to achieve electric adjustment and drive the long gear 112 to rotate.

[0049] The locking mechanism 12 of this utility model includes a limiting inner ring platform 121 with an adjustment hole 113, and an annular positioning toothed groove hole 122 on the limiting inner ring platform 121. The driving long gear 112 includes a long gear body 1121, a connecting shaft 1122 at the inner end of the long gear body 1121, a connecting round hole 1123 on the inner side wall of the receiving groove 10, the connecting shaft 1122 being movably disposed in the connecting round hole 1123, a second top pressure spring 123 being sleeved on the connecting shaft 1122, an annular toothed portion 1124 in the middle of the long gear body 1121, and a driving long gear 112... The drive gear 112 has a limiting end 1125. A positioning protruding ring tooth 1126 that can be inserted into the annular positioning tooth groove 122 is provided on the outer wall of the front part of the drive gear 112. A clearance portion 1127 is provided between the limiting end 1125 and the annular tooth portion 1124 to facilitate the movement of the gear body 1121 inward, thereby separating the positioning protruding ring tooth 1126 from the annular positioning tooth groove 122. A connecting thread 1128 is provided on the outer wall of the gear body 1121 between the positioning protruding ring tooth 1126 and the annular tooth portion 1124. A limiting collar 13 that can prevent the gear body 1121 from disengaging from the adjustment hole 113 is screwed onto the connecting thread 1128.

[0050] In this invention, the limiting inner ring platform 121 is disposed inside the adjusting hole 113, serving as an axial limiting structure for the driving long gear 112 to prevent excessive movement. The annular positioning tooth groove hole 122 is located on the limiting inner ring platform 121 and is used to engage and lock with the positioning convex ring tooth 1126 to prevent the driving long gear 112 from rotating unexpectedly.

[0051] When the present invention is in the locked state, the second top pressure spring 123 pushes the long gear body 1121 to move outward, so that the positioning convex ring tooth 1126 is embedded in the annular positioning tooth groove hole 122. At this time, the driving long gear 112 cannot rotate, ensuring height stability.

[0052] When the device is in the unlocked and adjusted state, after inserting the external tool into the adjusting inner hole 114, press the external tool firmly to drive the drive gear 112 to overcome the elastic force of the second top pressure spring 123 and move inward. The positioning convex ring tooth 1126 separates from the annular positioning tooth groove hole 122. At this time, the drive gear 112 can be rotated for height adjustment. After adjustment, release the drive gear 112. Under the action of the second top pressure spring 123, the positioning convex ring tooth 1126 re-engages into the annular positioning tooth groove hole 122, and the drive gear 112 is securely locked.

[0053] This invention provides a guide slot 14 within the base 1 on one side of the assembly groove 111. A guide plate 15 is positioned at the lower end of the lower baffle plate 21, corresponding to the guide slot 14, and is movably disposed within the guide slot 14. The cooperation between the guide plate 15 and the guide slot 14 ensures smoother movement of the lower baffle plate 21 and prevents lateral wobbling after adjustment.

[0054] The base 1 of this utility model includes a base body 101, chain connection holes 102 are provided at intervals on the lower part of the base body 101, and an arc-shaped guide surface 103 is provided on the inner side of the paper feed end of the base body 101 to facilitate paper entry.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
