Description

Technical Field

[0001] The utility model relates to the technical field of glue coating rollers, in particular to a glue coating roller for packaging printed products. Background Art

[0002] Corrugated cardboard is a common and widely used packaging product. It has penetrated into all aspects of our daily life. Because of its extremely wide range of applications, its usage has always been at the forefront of various packaging products. The composition of corrugated cardboard includes four parts, including face paper, core paper, lining paper and corrugated paper that has been processed to present a corrugated shape. It is made by gluing these four parts. Usually, when processing corrugated paper, it is necessary to coat the surface of the corrugated paper with glue. Corrugated paper gluing is also one of the important processing steps in production. The existing glue rollers are generally fixed on the support frame and cannot be disassembled, which makes it inconvenient to clean the residual glue on the glue rollers. Secondly, the thickness of the glue dipped on the outside of the glue roller is uneven, and the thickness of the glue cannot be adjusted and controlled.

[0003] For example, a gluing roller for corrugated paper processing disclosed in a Chinese patent document (publication number: CN217664260U) can facilitate the disassembly and assembly of the gluing roller body by utilizing a convenient disassembly and assembly mechanism, and facilitate the subsequent removal of the gluing roller body for cleaning or replacement. Secondly, by utilizing an adjustable scraping mechanism, the distance between the scraper and the gluing roller body can be accurately adjusted, thereby achieving scraping control of different glue thicknesses.

[0004] However, when disassembling the rubber coating roller body, one person is required to turn the hand-tightening bolt one to disengage the cross positioning block from the cross positioning groove, and at the same time, one person is required to hold the rubber coating roller body and wait for the cross positioning block to disengage from the cross positioning groove before taking out and disassembling the rubber coating roller body. The whole operation requires two people to cooperate in disassembly, which is rather cumbersome. During installation, one person is required to hold the rubber coating roller body and keep the cross positioning groove and the cross positioning block at the same horizontal line, and the other person turns the hand-tightening bolt one to move the cross positioning block into the cross positioning groove to complete the installation, which leads to high installation requirements and great installation difficulty.

[0025] Reference Figure 1-4 A packaging printing glue coating roller comprises a base 1, a glue storage box 2 is fixedly connected to the upper surface of the base 1, a symmetrically distributed support block 3 is fixedly connected to the upper surface of the base 1, a slot 4 is provided on one side surface of the support block 3, a positioning block 5 is fixedly connected to one side surface of the support block 3, a trapezoidal groove 6 is provided on the upper surface of the positioning block 5, a rectangular sleeve 7 is movably inserted into the inner wall of the slot 4, and the inclined surface of the trapezoidal groove 6 is arranged to guide and position the offset rectangular sleeve 7 when it is placed, so that when the rectangular sleeve 7 is aligned with the slot 4 for insertion and installation, the installation difficulty of the operator is reduced and the installation efficiency is improved;

[0026] The inner wall of the rectangular sleeve 7 is provided with a convenient disassembly device, and the convenient disassembly device includes a movable block 8 , and the outer surface of the movable block 8 is movably sleeved with the inner wall of the rectangular sleeve 7 .

[0027] A lifting handle 81 is fixedly connected to the upper surface of the rectangular sleeve 7, and the lifting handle 81 serves to facilitate the operator to drive the rectangular sleeve 7 to move. A support spring 82 is fixedly connected to the surface of one side of the movable block 8, and the elastic force of the support spring 82 serves to drive the rectangular sleeve 7 to move and reset. One end of the support spring 82 is fixedly connected to the inner wall of one side of the rectangular sleeve 7. The opposite surfaces of the two movable blocks 8 are both installed with a rotating rod 83 through a bearing. The outer surface of the rotating rod 83 is fixedly sleeved with a glue coating roller body 84. The glue coating roller body 84 plays a role in positioning and rotating for glue coating through the cooperation of the rotating rod 83 and the bearing. When the glue coating roller body 84 rotates to coat glue, it can be used in cooperation with the driving rollers arranged on both sides of it. The front sides of the two support blocks 3 are fixedly connected with mounting brackets 85, and the inner wall of the mounting bracket 85 is threaded with a screw 86.

[0028] One end of the screw rod 86 is fixedly connected to a driving handle 87, and the driving handle 87 serves to facilitate the screw rod 86 to rotate. An adjustment plate 88 is installed on the outer surface of the other end of the screw rod 86 through a bearing. A scraper 89 is fixedly connected to the back of the adjustment plate 88. The rotation of the screw 86 serves to drive the scraper 89 to move and adjust through the adjustment plate 88. A guide plate 810 is fixedly connected to the back of the adjustment plate 88, and a symmetrically distributed guide rod 811 is fixedly connected to the front of the adjustment plate 88. One end of the two guide rods 811 passes through and extends to the front of the mounting bracket 85, and the guide rods 811 serve to guide the movement of the adjustment plate 88.

[0029] By providing a convenient disassembly device, the glue roller body 84 can be disassembled and installed by a single person, thereby facilitating the disassembly and cleaning of the glue roller body 84. The disassembly and assembly operation is convenient, the labor cost is low, and the thickness of the corrugated paper glue can be adjusted.

[0030] Working principle: Step 1: When adjusting the glue coating thickness, the driving handle 87 drives the screw 86 to rotate clockwise, and the rotation of the screw 86 drives the adjustment plate 88 to move stably through the cooperation of the guide rod 811. The movement of the adjustment plate 88 drives the scraper 89 to move toward the glue coating roller body 84, so that when the glue coating roller body 84 rotates to apply glue, the scraper 89 scrapes off the glue part exceeding the thickness, and makes it flow into the glue storage box 2 through the guide plate 810, so as to realize the control of the glue coating thickness;

[0031] Step 2: When disassembling the glue coating roller body 84 for cleaning, hold the two lifting handles 81 and move them relative to each other. The movement of the lifting handles 81 squeezes and contracts the supporting spring 82 through the rectangular sleeve 7. When the rectangular sleeve 7 moves to disengage the slot 4 and then pulls it upward, the glue coating roller body 84 is taken out for cleaning through the cooperation of the movable block 8 and the rotating rod 83.

[0032] Step three, when installing the glue coating roller body 84, first hold the two lifting handles 81 and move them relative to each other. The movement of the lifting handles 81 squeezes and contracts the supporting spring 82 through the rectangular sleeve 7. The rectangular sleeve 7 is placed in the trapezoidal groove 6 through the lifting handles 81. The slot 4 is positioned by positioning the bottom end of the trapezoidal groove 6. At this time, release the lifting handles 81, and the elastic force of the supporting spring 82 drives one end of the rectangular sleeve 7 to be inserted into the slot 4, and the installation of the glue coating roller body 84 is completed.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0034] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
