Technical Field

[0001] This utility model relates to the field of specialty paper production technology, specifically a trailer-type screen changing device for specialty paper production. Background Technology

[0002] Specialty cigarette paper is a core material used in cigarette production to perform specific functions. It directly affects cigarette quality, smoking experience, and brand recognition. It mainly includes tipping paper, inner lining paper, label paper, forming paper, and moisture-proof paper. Tipping paper is used to connect the filter and the cigarette. It needs to be breathable, comfortable to the touch, and some have a tar-reducing and harm-reducing coating. Inner lining paper is responsible for wrapping the cigarette. Its core function is to prevent moisture and preserve aroma and avoid loss of tobacco flavor. Trailer-type screen changing device is a device specifically designed for manual replacement of screens in space-constrained areas.

[0003] The existing optimization technology does not require complicated disassembly and assembly. It can be operated with the help of a special support device. First, remove the clamping rod, place a jack in the groove to support the first support by about 2mm, then remove the pull-out seat, release the pressure of the jack to allow the suspension beam to sink to the appropriate state, and the netting can be replaced. When replacing, ensure that there is enough gap between the rollers so that the netting can be fitted in. Before the netting is flattened on each roller, the upper pressure roller and other components should not be dropped. After installation, run it slowly to wet the netting with water until it is saturated with water, and then adjust the tension roller to the optimal dehydration state. However, it is not convenient for manual operation in space-constrained places, has poor practicality, and is not easy to promote and use. Summary of the Invention

A pull rod 25 is provided on the outer wall of the trailer body 1.

[0023] Specifically, a guide block 4 is fixedly installed on the side of the trailer body 1 near the support 2. A threaded hole 5 is provided on the side of the trailer body 1 near the support 2. A guide groove 6 and a threaded hole 7 are provided on the end of the support 2 near the trailer body 1. A bolt 8 is threadedly connected to the end of the support 2 near the trailer body 1. The guide block 4 and the guide groove 6 are plug-in installed. The cross-section of the guide block 4 is trapezoidal. The advantage is that by inserting the guide block 4 into the guide groove 6, the support 2 can be quickly positioned without repeated adjustments to its position, significantly shortening assembly time.

[0024] Specifically, bolt 8 extends through threaded hole 7 into threaded hole 5, and threaded hole 7 has the same diameter as threaded hole 5. The advantage is that after the support 2 is quickly positioned, the operator can quickly fix the support 2 by extending bolt 8 through threaded hole 7 into threaded hole 5. After long-term use, it is convenient to inspect or replace it.

[0025] Specifically, a positioning block 16 is fixedly installed on the side of the foundation embedded part 14 near the base 15. A positioning groove 17 and a threaded hole 18 are formed on the side of the foundation embedded part 14 near the base 15. A positioning groove 19 and a threaded hole 20 are formed on the side of the base 15 near the foundation embedded part 14. A positioning block 21 is fixedly installed on the side of the base 15 near the foundation embedded part 14. A bolt 22 is threadedly connected to one end of the base 15 near the foundation embedded part 14. Positioning block 16 and positioning groove 19 are inserted into each other, and positioning block 21 and positioning groove 27 are also inserted into each other. The advantage is that workers can quickly position the base 15 by inserting positioning block 16 into positioning groove 19 and simultaneously inserting positioning block 21 into positioning groove 27, eliminating the need for repeated adjustments to the base 15's position and significantly shortening assembly time.

[0026] Example 2: Figure 2-5 As shown, this is an improvement on the previous embodiment.

[0027] Specifically, bolt 22 extends through threaded hole 4 20 into threaded hole 3 18, and threaded hole 4 20 and threaded hole 3 18 have the same diameter. The advantage is that after the base 15 is quickly positioned, the operator can quickly fix the base 15 by extending bolt 22 through threaded hole 4 20 into threaded hole 3 18, which facilitates quick assembly and disassembly during use or assembly.

[0028] Specifically, the limiting block 13 is adapted to the limiting groove 23, and the limiting pin 3 passes through the through hole 3 12. The advantage is that when the worker pulls the pull rod 25, the omnidirectional wheel 24 moves the trolley to the workstation. After the worker drags the two trolleys to the workstation, the omnidirectional wheel 24 brakes, and the pull rod 9 is inserted into the base 15. At the same time, the limiting block 13 is inserted into the limiting groove 23. Then the pull rod 9 is rotated so that the limiting block 13 is located at the innermost side of the limiting groove 23, which can lock the pull rod 9, so that the trolley is not pulled up when the net is pulled up. Then the net is installed on the two trolley supports 2, ready for net replacement.

[0029] Specifically, through hole 10 is connected to through hole 21, and through holes 10, 21, and 32 have the same diameter. The advantage is that after the net replacement is completed, the worker removes the main support core, then rotates pull rod 19, pulls pull rod 19 out of base 15, and then inserts the limiting pin 3 through through hole 21 and through hole 10 to limit pull rod 19. Then, the brake on the universal wheel 24 is released, and the worker removes the trolley, thus completing the net replacement.

[0030] Working Principle: During installation, the operator inserts guide block 4 into guide groove 6, enabling quick positioning of support 2. Initial positioning is achieved without repeated adjustments to support 2, significantly reducing assembly time. After quick positioning of support 2, bolt 8 is inserted through threaded hole 7 to threaded hole 5, quickly fixing support 2 and facilitating maintenance or replacement after prolonged use. Then, positioning block 16 is inserted into positioning groove 19, and positioning block 21 is inserted into positioning groove 17, enabling quick positioning of base 15 without repeated adjustments, further reducing assembly time. After quick positioning of base 15, bolt 22 is inserted through threaded hole 20 to threaded hole 18, quickly fixing base 15. For easy and quick assembly or disassembly, the operator pulls lever 25 to move the trolley to the workstation via caster 24. After the two trolleys are moved to the workstation, caster 24 is braked, and lever 9 is inserted into the base 15. At the same time, limit block 13 is inserted into the limit groove 23. Lever 9 is then rotated so that limit block 13 is located at the innermost side of limit groove 23, which can hold lever 9 in place, preventing the trolley from being pulled up when the net is pulled up. The net is then installed on the two trolley supports 2, ready for net replacement. After the net replacement is completed, the operator removes the dry net support core, then rotates lever 9 and pulls lever 9 out of base 15. Limit pin 3 is then inserted through through hole 11 and through hole 10 to limit lever 9. The brake on caster 24 is then released, and the trolley is removed. The net replacement is now complete.
