[0027] Reference Figure 1-4 , an embodiment provided by the utility model:

[0029] A No. 1 mounting block 7 is movably embedded at the midpoint of the two movable grooves 20. The two No. 1 mounting blocks 7 are rotatably sleeved with a No. 1 connecting shaft 22. The two No. 2 mounting blocks 10 are rotatably sleeved with a No. 2 connecting shaft 24 on the opposite side. The rear ends of the No. 1 connecting shaft 22 and the No. 2 connecting shaft 24 are fixedly sleeved with a No. 1 gear 21 and a No. 2 gear 23 respectively. The upper ends of the two No. 1 mounting blocks 7 are fixedly provided with a connecting spring 6 and the upper end of the connecting spring 6 is fixedly provided with a pushing block 5. The upper end of the pushing block 5 is fixedly connected to the pushing rod 4. A screw 29 is rotatably provided inside the mounting plate 3 and a worm gear 28 is fixedly sleeved on the outside of the screw 29. The screw 29 is threadedly sleeved with the pushing rod 4.

[0030] Specifically, the cutting knife 13 is installed at the lower end of the pressing rod 1. When cutting is needed, the pressing rod 1 can be squeezed downward to drive the cutting knife 13 at the lower end to move downward, and the downward-moving cutting knife 13 can be used to cut off the excess tape at the rear end of the base paper; the rotating shaft 16 with the tape roller 19 is installed in the track groove 15. According to the different positions of the rotating shaft 16 in the track groove 15, the tension can be assisted to be adjusted according to the use needs.

[0031] Reference Figure 1 、 Figure 2 and Figure 3A paper feeding platform 14 is fixedly provided at the lower end of the opposite side of the two side panels 8, and the paper feeding platform 14 is located at the lower end of the cutting knife 13; a through hole 12 is opened at the midpoint of the side of the opposite side of the two side panels 8 close to the movable groove 20, and the front and rear ends of the cutting knife 13 are respectively embedded in the two through holes 12; the outer sides of the two pressing rods 1 are sleeved with a contraction spring 18, and the contraction spring 18 is located between the lower surface of the top of the pressing rod 1 and the upper surface of the side panel 8;

[0032] Specifically, the paper feeding platform 14 can provide auxiliary support for the base paper during the sealing process of the base paper, and form a pushing platform, while providing auxiliary support for the cutting point when the cutting knife 13 is cutting; a contraction spring 18 is sleeved on the outside of the pressing rod 1, and the contraction spring 18 contracts when pressing, and the contraction spring 18 resets after the pressing force is withdrawn to achieve the automatic reset effect of the cutting knife 13 and the pressing rod 1.

[0033] Reference Figure 1 and Figure 2 The front and rear ends of the two rotating shafts 16 are both threaded with fastening bolts 17, and the fastening bolts 17 fit into the outer wall of the side plate 8 to achieve a fastening and clamping effect; the position of the rotating shaft 16 can be adjusted as needed, and at the same time, it has an auxiliary fixing effect.

[0034] Reference Figure 1-5 , the outer side of the No. 1 connecting shaft 22 is fixedly sleeved with a No. 1 rubber roller 25, the outer side of the No. 2 connecting shaft 24 is fixedly sleeved with a No. 2 rubber roller 26, and the lower end of the No. 1 rubber roller 25 is movably fitted with the upper end of the No. 2 rubber roller 26. The end of the No. 1 connecting shaft 22 away from the No. 1 gear 21 is fixedly provided with a turning handle 11, and the No. 1 gear 21 and the No. 2 gear 23 are meshed. The adjusting rod 2 is located on the outer wall of the mounting plate 3 and is fixedly sleeved with a worm 27. The worm 27 is meshed with the worm gear 28. The waterproof tapes sleeved on the two tape reels 19 pass between the two rubber rollers with the coated surfaces facing each other;

[0035] Specifically, when in use, the upper end of the adjusting rod 2 can be used to rotate and drive the worm 27 to rotate. The rotation of the worm 27 drives the worm wheel 28 to rotate, and the rotation of the worm wheel 28 drives the screw 29 to rotate. When the screw 29 rotates, it is threadedly engaged with the push rod 4, and the lower end of the push rod 4 is fixedly connected to the push block 5. At this time, the push rod 4 moves downward and drives the push block 5 to move downward, thereby changing the contraction deformation degree of the connecting spring 6 at the lower end, causing the thrust required for the No. 1 rubber roller 25 at the lower end to rise to change;

[0036] When it is necessary to drive the rubber roller, the handle 11 is turned to drive the No. 1 connecting shaft 22 to rotate, and the No. 1 gear 21 at the rear end of the No. 1 connecting shaft 22 drives the No. 2 gear 23, followed by synchronous rotation of the No. 2 connecting shaft 24, thereby realizing the synchronous rotation of the No. 1 rubber roller 25 and the No. 2 rubber roller 26, thereby realizing the push-sealing work of the base paper and the tape placed between the No. 1 rubber roller 25 and the No. 2 rubber roller 26, and realizing the double-sided tape bonding of the base paper.

[0037] Working principle: When in use, the base paper is placed between the No. 1 rubber roller 25 and the No. 2 rubber roller 26, and then the waterproof tape on the two tape rolls 19 is passed between the two rubber rollers with the adhesive surfaces facing each other. At this time, according to the sealing force required, the adjusting rod 2 is rotated to drive the internal worm 27 to rotate, so that the inner worm wheel 28 and the screw 29 rotate. The rotation of the screw 29 causes the push rod 4 connected by the lower thread to move downward, driving the push block 5 to move downward, generating an extrusion force on the connecting spring 6, causing the elastic deformation of the connecting spring 6 to change. At this time, the force required for the No. 1 rubber roller 25 to move upward changes, thereby better performing the sealing work.

[0038] Secondly, by turning the handle 11, the No. 1 rubber roller 25 is driven to rotate, and the No. 1 gear 21 and the No. 2 gear 23 at the rear end are engaged, prompting the No. 2 rubber roller 26 to rotate synchronously to push the base paper. After sealing is completed, the pressing rod 1 can be pressed down to drive the cutting knife 13 to move downward to complete the cutting of the waterproof tape.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
