[0029] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] like Figure 1-5 As shown, this embodiment provides a retractable belt paper splicing device, which is composed of a main frame 4, an upper retractable pressure wheel assembly and a lower retractable belt assembly.

[0031] The main frame 4 is composed of an upper frame and a lower frame, and the upper frame and the lower frame are fixedly connected.

[0032] The lower telescopic belt assembly consists of a belt driving wheel assembly 1, a telescopic belt 2, a lower guide telescopic plate 3, a lower sliding assembly, etc.

[0033] The lower guide telescopic plate 3 slides horizontally on the main frame 4 via a lower sliding assembly. Specifically, the lower sliding assembly consists of a lower cylinder 7, a lower cylinder top plate 8, a lower lower rail 9, and a lower slider 10. The movable rod of the lower cylinder 7 is fixedly connected to the lower cylinder top plate 8, which is in turn fixedly connected to the lower guide telescopic plate 3. The lower rail 9 is horizontally and fixedly mounted on the lower guide telescopic plate 3. The lower slider 10 is fixedly mounted on the main frame 4 and slidably connected to the lower rail 9. Therefore, as the movable rod of the lower cylinder 7 extends or retracts, it drives the lower cylinder top plate 8 to slide, allowing the lower guide telescopic plate 3 to stably extend and retract under the action of the lower rail 9 and lower slider 10.

[0034] The belt drive pulley assembly 1 is composed of a belt driving pulley 101, a belt driven pulley 102, multiple belt abutment pulleys 103, a follower abutment pulley 5, etc., wherein the rotation of the belt driving pulley 101 is realized by a chain drive assembly (motor, chain, chain gear); multiple belt abutment pulleys 103, chain drive assembly and belt driving pulley 101 are installed on the main frame 4, the belt driven pulley 102 is rotatably installed at the front end of the lower guide telescopic plate 3, and the follower abutment pulley 5 is rotatably installed in the vertical middle position of the lower guide telescopic plate 3.

[0035] The two ends of the telescopic belt 2 are connected to a belt driving pulley 101 and a belt driven pulley 102, respectively. Multiple belt abutment pulleys 103 and a follower abutment pulley 5 abut against the telescopic belt 2, causing the telescopic belt 2 to serpentine. Therefore, as the lower guide telescopic plate 3 extends or retracts, it drives the telescopic belt 2 to extend or retract. The follower abutment pulley 5 keeps the telescopic belt 2 taut at all times.

[0036] The upper telescopic pressing wheel assembly is composed of a plurality of telescopic pressing wheels 6, an upper guide telescopic plate 11 and an upper sliding assembly.

[0037] A plurality of telescopic pressing wheels 6 are rotatably mounted on the upper guide telescopic plate 11. Normally, a plurality of telescopic pressing wheels 6 maintain the same horizontal height, but, in order to adapt to actual conditions, the horizontal position of the telescopic pressing wheel 6 near the paper receiving passage inlet may be slightly higher.

[0038] The upper guide telescopic plate 11 slides horizontally on the main frame 4 via an upper sliding assembly. Specifically, the upper sliding assembly consists of an upper cylinder 12, an upper cylinder top plate 13, an upper slide rail 14, and an upper slider. The movable rod of the upper cylinder 12 is fixedly connected to the upper cylinder top plate 13, which is in turn fixedly connected to the upper guide telescopic plate 11. The upper slide rail 14 is horizontally and fixedly mounted on the upper guide telescopic plate 11. The upper slider is fixedly mounted on the main frame 4 and is slidably connected to the upper slide rail 14. Therefore, as the movable rod of the upper cylinder 12 extends or retracts, it drives the upper cylinder top plate 13 to slide, allowing the upper guide telescopic plate 11 to stably extend and retract under the action of the upper slide rail 14 and the upper slider.

[0039] A paper receiving channel is formed between the telescopic pressing wheel 6 and the telescopic belt 2. The telescopic pressing wheel 6 contacts the upper surface of the paperboard, and the telescopic belt 2 contacts the lower surface of the paperboard.

[0040] The front end of the lower guide telescopic plate 3 of the lower telescopic belt assembly is fixedly installed with an arc-shaped inlet lower plate 15, and the front end of the upper guide telescopic plate 11 of the upper telescopic pressure wheel assembly is installed with an auxiliary connecting plate 16 and an arc-shaped inlet upper plate 17. The auxiliary connecting plate 16 is fixedly installed on the upper guide telescopic plate 11 by bolts, and the side of the arc-shaped inlet upper plate 17 is extended and a waist-shaped groove is opened in the extended part. The arc-shaped inlet upper plate 17 is slidably set on the auxiliary connecting plate 16 by bolts passing through the waist-shaped groove. An arc-shaped inlet of the paper receiving channel is formed between the arc-shaped inlet upper plate 17 and the arc-shaped inlet lower plate 15.

[0041] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any person skilled in the art can, without departing from the scope of the present invention, utilize the methods and technical content disclosed above to make many possible variations and modifications to the present invention, or modify it into equivalent embodiments with equivalent variations. Therefore, any equivalent variations based on the shape, structure, and principle of the present invention that do not depart from the content of the present invention are intended to be covered by the scope of protection of the present invention.
