[0001] The invention relates to the technical field of thermal paper collection, in particular to a thermal paper rotary collector. Background Art

[0002] Thermal paper is a type of paper that is extremely sensitive to temperature. Its surface is covered with a unique thermal coating. When the coating encounters a suitable temperature, a chemical reaction is triggered, resulting in a color change, which in turn forms clear text or images. After using thermal paper, in order to ensure the effective use of resources, it needs to be recycled, which is inseparable from the assistance of a thermal paper rotary collector.

[0003] However, the traditional partial thermal paper rotary collector cannot adjust the rewinding force.

[0021] In the present invention, unless otherwise stated, the directions such as "upper and lower" are generally in the direction shown in the drawings, or in the vertical, perpendicular or gravitational direction; similarly, for the convenience of understanding and description, "left and right" are generally left and right as shown in the drawings; "inside and outside" refer to the inside and outside of the contour of each component itself, but the above direction terms are not used to limit the present invention.

[0022] The present invention provides a technical solution: Please refer to Figures 1 to 11 , a thermal paper rotary collector, including a base 1 and a bracket 2 fixedly installed on the base 1. The bracket 2 is integrally L-shaped, and a rewinding force regulating mechanism 3 is arranged on the bracket 2. The rewinding force regulating mechanism 3 can be used to control the rewinding force of the thermal paper. This design effectively solves the problem that the rewinding force of the traditional thermal paper rotary collector is uncontrollable.

[0023] The rewinding force regulating mechanism 3 includes a hollow rewinding member 301 rotatably connected to the bracket 2 and passing through the bracket 2. One end of the hollow rewinding member 301 is fixedly installed with a servo motor 302. The output end of the servo motor 302 is fixedly connected to the hollow rewinding member 301. An air extraction pump 303 is fixedly installed on the hollow rewinding member 301. The air extraction end of the air extraction pump 303 is communicated with the inner cavity of the hollow rewinding member 301.

[0024] The rewinding force regulating mechanism 3 is composed of a hollow rewinding member 301 rotatably connected to the bracket 2, a servo motor 302 and an air extraction pump 303. The servo motor 302 is used to drive the hollow rewinding member 301 to rotate, and the air extraction pump 303 extracts the air inside the hollow rewinding member 301 to form a negative pressure, firmly adsorbing and fixing the thermal paper.

[0025] The inner side of the bracket 2 is rotatably connected with a paper feeding roller 304. A spring groove is formed inside the bracket 2. A telescopic spring 305 is fixedly installed at the bottom of the inner cavity of the spring groove. The top of the telescopic spring 305 is fixedly installed with a concave bracket 306. The inner side of the concave bracket 306 is rotatably connected with a pressure roller 3061. The pressure roller 3061 is located directly above the paper feeding roller 304. Above the concave bracket 306, there is a pressing rod 307 rotatably connected with the bracket 2. A number of arc-shaped pressing blocks 308 are fixedly installed on the pressing rod 307. One end of the pressing rod 307 is fixedly installed with a pressing rod driving wheel 309. The outer side of the pressing rod driving wheel 309 is drivingly connected with a belt 310. One end of the inner side of the belt 310 far from the pressing rod driving wheel 309 is drivingly connected with a linkage member 311. The outer side of the linkage member 311 is provided with a mounting housing 312 adapted to the linkage member 311. The mounting housing 312 is fixedly connected with the bracket 2. Diagonally above the linkage member 311, there is a positioning member 313 fixedly connected with the bracket 2.

[0026] The paper feeding roller 304 and the pressure roller 3061 are assembled and installed on the bracket 2. The pressure roller 3061 is connected with the bracket 2 through the concave bracket 306 and the telescopic spring 305 to form an elastic pressure adjustment mechanism. The pressing rod 307 is linked with the winding roller 3011 through the belt 310 and the linkage member 311. The arc-shaped pressing blocks 308 on the pressing rod 307 press on the concave bracket 306 as the winding roller 3011 rotates, adjusting the distance between the pressure roller 3061 and the paper feeding roller 304, so as to precisely control the winding force. The positioning member 313 cooperates with the linkage member 311 to achieve precise positioning and locking. During the working process of this structure, the servo motor 302 drives the winding roller 3011 to rotate, and the pressure of the pressure roller 3061 is adjusted in a linked manner, ensuring that the thermal paper will neither be damaged due to being too tight nor be loose and wrinkled due to being too loose during winding, effectively improving the winding quality and reuse efficiency of the thermal paper, and playing a key role in regulating the winding force.

[0027] In some embodiments, the hollow winding member 301 includes a winding roller 3011. A thermal paper placement groove 3012 is formed inside the winding roller 3011. A number of air suction holes 3013 communicating with the inner cavity of the winding roller 3011 are formed at the bottom of the inner cavity of the thermal paper placement groove 3012; a number of cylindrical sliding grooves 3014 are formed inside the winding roller 3011. A support spring 3015 is fixedly installed at the bottom of the inner cavity of the cylindrical sliding groove 3014. The top of the support spring 3015 is fixedly installed with a sealing slider 3016 adapted to the cylindrical sliding groove 3014. The sealing performance between the sealing slider 3016 and the cylindrical sliding groove 3014 is good. A lifting rod 3017 penetrating the sealing slider 3016 is fixedly installed at the center of the sealing slider 3016. The lifting rod 3017 penetrates the winding roller 3011; a motor frame is provided at the bottom of the servo motor 302. The motor frame is fixedly connected with both the servo motor 302 and the bracket 2.

[0028] In this embodiment, the thermal paper placement groove 3012 opened inside the winding roller 3011 provides a placement space for the thermal paper. The air suction holes 3013 are connected to the inner cavity of the winding roller 3011, and an air extraction pump 303 is used to extract the gas inside the winding roller 3011 (both ends of the winding roller 3011 are sealed), forming a negative pressure adsorption mechanism to ensure the stable adsorption of the thermal paper at the initial stage of winding. The combination of the support spring 3015 and the sealing slider 3016 in the cylindrical chute 3014 realizes the flexible control of the motion states of the winding roller 3011 and the linkage transmission wheel 3111 through the good sealing performance between the sealing slider 3016 and the cylindrical chute 3014 and the penetration design of the lifting rod 3017. When the winding force reaches the preset value, the power of the air extraction pump 303 increases, and the sealing slider 3016 contracts under the action of the support spring 3015, causing the lifting rod 3017 to disengage from the linkage insertion cylinder 3113 on the linkage member 311, and the winding roller 3011 rotates independently to complete the winding. This design not only ensures the stability and flatness of winding, but also saves production costs through the barrel-free winding method and improves the practicality of the equipment. The servo motor 302 is fixed by the motor frame, provides stable power for the winding roller 3011, and plays a core driving role in the whole winding process.

[0029] In some embodiments, the linkage member 311 includes a linkage transmission wheel 3111. A number of positioning grooves 3112 are formed on the linkage transmission wheel 3111. A number of linkage insertion cylinders 3113 are fixedly installed on the inner circular surface of the linkage transmission wheel 3111. The arc of the end of the linkage insertion cylinder 3113 close to the winding roller 3011 is equal to the arc of the outer circular surface of the winding roller 3011. The linkage transmission wheel 3111 is rotatably connected to the mounting housing 312.

[0030] In this embodiment, the linkage member 311 ensures the precise regulation of the winding force. The cooperation between the number of positioning grooves 3112 formed on the linkage transmission wheel 3111 and the positioning member 313 realizes the precise positioning and locking of the position of the linkage transmission wheel 3111. The arc of the linkage insertion cylinder 3113 fixed on the inner circular surface of the linkage transmission wheel 3111 matches the arc of the outer circular surface of the winding roller 3011, ensuring the smoothness and high efficiency of the transmission process. When the servo motor 302 drives the winding roller 3011 to rotate, the linkage transmission wheel 3111 is connected to the pressure rod transmission wheel 309 through the belt 310, driving the pressure rod 307 and the arc-shaped pressure block 308 to rotate, and then adjusting the distance between the pressure roller 3061 and the paper feeding roller 304 to realize the fine control of the winding force of the thermal paper. In this process, the linkage member 311 not only transmits power, but also ensures the accuracy and stability of the transmission, which plays a crucial role in improving the winding quality and reuse efficiency of the thermal paper.

[0031] In some embodiments, the clamping member 313 includes an electric telescopic rod mounting bracket 3131 fixedly installed on the bracket 2. An electric telescopic rod 3132 is fixedly installed on the electric telescopic rod mounting bracket 3131. A clamping block 3133 adapted to the positioning groove 3112 is fixedly installed at the output end of the electric telescopic rod 3132.

[0032] In this embodiment, when the winding force reaches the preset value, the electric telescopic rod 3132 drives the clamping block 3133 to accurately insert into the corresponding positioning groove 3112 on the linkage transmission wheel 3111, realizing the locking of the linkage transmission wheel 3111, ensuring that the winding roller 3011 does not drive the linkage member 311 to rotate when rotating alone, thereby ensuring the stability of winding.

[0033] Please refer to Figures 1 to 5 and Figure 7 As shown in the figure, a dust cleaning mechanism 4 is provided on the winding roller 3011. The dust cleaning mechanism 4 includes a driving gear 401 fixedly installed on the winding roller 3011. A driven gear 402 is meshed outside the driving gear 401. A dust cleaning frame 403 fixedly connected to the bracket 2 is provided on one side of the driven gear 402. A dust cleaning shaft 404 penetrating the driven gear 402 is rotatably connected to the dust cleaning frame 403. The dust cleaning shaft 404 is fixedly connected to the driven gear 402. A dust cleaning main gear 405 is fixedly installed at one end of the dust cleaning shaft 404 away from the driven gear 402. An upper dust cleaning cylinder 406 and a lower dust cleaning cylinder 407 are rotatably connected to the inner side of the dust cleaning frame 403 from top to bottom in sequence. The upper dust cleaning cylinder 406 and the lower dust cleaning cylinder 407 are tangent to each other. An upper dust cleaning slave gear 408 meshed with the dust cleaning main gear 405 is fixedly installed on the upper dust cleaning cylinder 406. A lower dust cleaning slave gear 409 meshed with the dust cleaning main gear 405 is fixedly installed on the lower dust cleaning cylinder 407. Water collecting plates 410 are fixedly installed at the top and bottom of the inner cavity of the dust cleaning frame 403. A plurality of atomizing nozzles 411 are fixedly installed on the water collecting plates 410. A U-shaped pipe 412 communicating with the inner cavity of the water collecting plate 410 is fixedly installed outside the water collecting plate 410. The U-shaped pipe 412 penetrates the dust cleaning frame 403. An external connecting pipe 413 communicating with the inner cavity of the U-shaped pipe 412 is fixedly installed on the U-shaped pipe 412. A sliding strip 414 is fixedly installed at the top of the dust cleaning frame 403. A thermal paper track limiting member 415 is slidably connected to the inner cavity of the sliding strip 414. The number of the thermal paper track limiting members 415 is two.

[0034] During the working process, when the winding roller 3011 rotates, the driving gear 401 drives the driven gear 402 to rotate, thereby driving the dust cleaning shaft 404 and the main dust cleaning gear 405 to rotate. The main dust cleaning gear 405 drives the upper dust cleaning cylinder 406 and the lower dust cleaning cylinder 407 to rotate through meshing with the upper dust cleaning driven gear 408 and the lower dust cleaning driven gear 409, realizing effective cleaning of dust and impurities on the surface of the thermal paper. At the same time, the atomizing nozzle 411 on the water collecting plate 410 introduces liquid (such as alcohol) through the U-tube 412 and the external connecting pipe 413 to appropriately moisten the dust cleaning cylinder, reduce static electricity generation, and improve the dust cleaning effect. The thermal paper track limiting member 415 adjusts its position through the slide bar 414 to ensure the stability of the thermal paper during the dust cleaning process. The dust cleaning mechanism 4 not only ensures the cleanliness of the collected thermal paper, but also, through its efficient working mechanism, coordinates with the winding force regulating mechanism 3 to ensure the smooth progress of the entire winding process, significantly improving the overall performance of the equipment and the reuse quality of the thermal paper.

[0035] In some embodiments, the thermal paper track limiting member 415 includes a right-angle frame 4151, a pressing bolt 4152 passing through the right-angle frame 4151 is threadedly connected to the right-angle frame 4151, and a V-block 4153 is fixedly installed at the bottom of the right-angle frame 4151.

[0036] In this embodiment, the thermal paper track limiting member 415 plays a role of precise positioning during the working process of the thermal paper rotary collector. By sliding the right-angle frame 4151 to adjust the position of the V-block 4153 to make it fit both sides of the thermal paper, and then rotating the pressing bolt 4152 to fix it, it is ensured that the thermal paper is stable and does not shift during the winding process. This design effectively prevents winding problems caused by the deviation of the thermal paper, ensures the winding quality and efficiency, and is a key component to ensure the smooth collection of the thermal paper.

[0037] Please refer to Figures 1 to 3 and Figure 5 , a stabilizing seat 5 is fixedly installed at the top of the bracket 2 directly below the winding roller 3011. A center of the top of the stabilizing seat 5 is fixedly installed with an electric air rod 6. An output end of the electric air rod 6 is fixedly installed with a winding roller support 7 adapted to the winding roller 3011. The winding roller support 7 is slidably connected to the stabilizing seat 5.

[0038] After the thermal paper is completely wound up, the PLC controller 8 controls the electric air rod 6 to start. The output end of the electric air rod 6 pushes the winding roller support 7 to slide down on the stable base 5, thereby driving the winding roller 3011 to move down, so that the wound-up thermal paper can be conveniently taken out. During the winding process, the stable base 5 provides a stable support foundation to ensure that the winding roller 3011 does not shake during high-speed rotation, guaranteeing the stability and quality of winding. This design not only simplifies the operation of taking out the thermal paper after winding, improves work efficiency, but also ensures the smooth progress of the entire winding process through a stable support structure, which plays a significant role in improving the winding quality and reuse efficiency of thermal paper.

[0039] Please refer to Figures 1 to 8 , the PLC controller 8 is fixedly installed on the bracket 2. The PLC controller 8 is electrically connected to the servo motor 302, the air extraction pump 303, the electric telescopic rod 3132 and the electric air rod 6.

[0040] The PLC controller 8 realizes the automatic control of the entire winding process by electrically connecting the servo motor 302, the air extraction pump 303, the electric telescopic rod 3132 and the electric air rod 6. During the working process, the PLC controller 8 precisely regulates the operation of each component. For example, it starts the air extraction pump 303 to form a negative pressure to fix the thermal paper, controls the servo motor 302 to drive the winding roller 3011 to rotate, and locks the linkage transmission wheel 3111 through the electric telescopic rod 3132 to ensure stable winding. After winding is completed, the PLC controller 8 controls the electric air rod 6 to move the winding roller support 7 to facilitate the taking out of the thermal paper. It improves the degree of automation of the equipment and ensures the accuracy and efficiency of the winding process.

[0041] The working principle of the present invention is as follows: When using this device, first do the preparatory work. Pass the used thermal paper through between the pressure roller 3061 and the paper feeding roller 304 (the surfaces of the pressure roller 3061 and the paper feeding roller 304 have elasticity, such as rubber cylinders), and pass the thermal paper through between the upper dust cleaning cylinder 406 and the lower dust cleaning cylinder 407. Place one end of the thermal paper on the thermal paper placement groove 3012, and make the thermal paper cover some of the air suction holes 3013. Adjust the thermal paper track limiting member 415 according to the lateral width of the thermal paper. Specifically, slide the right-angle brackets 4151 and the V-blocks 4153 on both sides in the slide bar 414. When the V-blocks 4153 are slid to both sides of the thermal paper, then rotate the pressing bolts 4152 so that the pressing bolts 4152 tightly abut against the slide bar 414, achieving the effect of fixing the position of the V-blocks 4153, ensuring the stability during the winding of the thermal paper, and avoiding the thermal paper from shifting during the winding process, which affects normal winding.

[0042] Connect a container filled with alcohol to the external connection pipe 413, and use a water pump to pump out the alcohol in the container. The alcohol is transported through the U-shaped pipe 412 to the water collecting plate 410 and sprayed out from the atomizing nozzle 411 onto the upper ash cleaning cylinder 406 and the lower ash cleaning cylinder 407. Just keep the upper ash cleaning cylinder 406 and the lower ash cleaning cylinder 407 moderately wet to avoid excessive wetting affecting the thermal paper. (At the same time, the upper ash cleaning cylinder 406 and the lower ash cleaning cylinder 407 can moderately and reasonably wet the thermal paper, reducing the generation of static electricity during the winding process and the impact of static electricity on the winding of the thermal paper).

[0043] After the preparatory work is done, the PLC controller 8 starts the air extraction pump 303 to extract the air inside the winding roller 3011, creating a negative pressure inside the winding roller 3011, which firmly adsorbs and fixes the thermal paper on the thermal paper placement groove 3012 to the winding roller 3011. (At this time, the suction force of the air extraction pump 303 is less than the elastic force of the support spring 3015 on the sealing slider 3016, that is, one end of the lifting rod 3017 is inserted into the linkage insertion cylinder 3113 in the initial state, and the linkage transmission wheel 3111 will rotate synchronously with the winding roller 3011). Compared with traditional winding devices, when this device winds thermal paper, it can complete the winding operation of the thermal paper without using a winding cylinder, achieving cylinder-free winding, greatly saving production costs and being more practical.

[0044] At this time, adjust the thermal paper located between the pressure roller 3061, the paper feeding roller 304 and the winding roller 3011 to make it in a straightened state, and then adjust the winding force of the thermal paper. Specifically, start the servo motor 302. The servo motor 302 drives the winding roller 3011 to rotate. The winding roller 3011 drives the belt 310 to drive, and the belt 310 drives the pressure rod transmission wheel 309 to rotate. The pressure rod transmission wheel 309 drives the pressure rod 307 and the arc-shaped pressure block 308 to rotate. When the arc-shaped pressure block 308 rotates to a certain extent, the arc-shaped pressure block 308 will press the concave frame 306 obliquely downward. During the downward movement of the concave frame 306, the telescopic spring 305 will be compressed, prompting the pressure roller 3061 to move downward, forcing the distance between the pressure roller 3061 and the paper feeding roller 304 to decrease. (The pressure roller 3061 and the paper feeding roller 304 will press the thermal paper located between them and apply pressure to it. Controlling the pressure between the pressure roller 3061 and the paper feeding roller 304 on the thermal paper is equivalent to controlling the winding force of the wound thermal paper).

[0045] When the pressure roller 3061 moves down to the specified position, stop the operation of the servo motor 302, that is, when the winding force of the thermal paper reaches the preset value. At this time, use the positioning member 313 to limit the movement of the linkage transmission wheel 3111. Specifically, the PLC controller 8 controls the electric telescopic rod 3132 to move, prompting the block 3133 to insert into the corresponding positioning groove 3112 on the linkage transmission wheel 3111, preventing the linkage transmission wheel 3111 from rotating. At this time, increase the power of the air extraction pump 303. The suction force of the air extraction pump 303 is greater than the elastic force of the support spring 3015 on the sealing slider 3016. A strong negative pressure will be generated on the winding roller 3011, the support spring 3015 will be compressed, and the sealing slider 3016 will contract inward along the cylindrical chute 3014, causing the lifting rod 3017 to disengage from the linkage insertion cylinder 3113, that is, releasing the restriction of the lifting rod 3017 on the linkage transmission wheel 3111. At this time, the linkage transmission wheel 3111 will not rotate with the winding roller 3011. Then start the servo motor 302, and the winding roller 3011 rotates independently to wind the thermal paper.

[0046] At the same time, the winding roller 3011 will also drive the driving gear 401 to rotate. The driving gear 401 will drive the driven gear 402 to rotate. The driven gear 402 drives the cleaning shaft 404 on the dust cleaning frame 403 to rotate (the dust cleaning frame 403 is composed of a cross concave frame and a rectangular frame). The cleaning shaft 404 drives the main cleaning gear 405 to rotate. The rotation of the main cleaning gear 405 drives the upper cleaning driven gear 408 and the lower cleaning driven gear 409 to rotate. The rotation of the upper cleaning driven gear 408 and the lower cleaning driven gear 409 drives the upper cleaning cylinder 406 and the lower cleaning cylinder 407 to rotate (the upper cleaning cylinder 406 and the lower cleaning cylinder 407 can be made of sponge cylinders). At this time, the dust and impurities attached to the thermal paper will be cleaned by the upper cleaning cylinder 406 and the lower cleaning cylinder 407, ensuring the cleanliness of the collected thermal paper.

[0047] After the thermal paper winding is completed, use the PLC controller 8 to control the electric air rod 6 to retract, causing the winding roller support 7 to move down. At this time, the thermal paper wound on the winding roller 3011 can be taken out.

[0048] In summary, through the winding force regulation mechanism 3 and the dust cleaning mechanism 4, this thermal paper rotary collector effectively solves the deficiencies in the winding force regulation and dust cleaning effect of traditional thermal paper rotary collectors. It can not only ensure the stability and flatness of the thermal paper during the winding process, but also significantly improve the reuse efficiency and quality of the thermal paper.

[0049] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements, or modifications made based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all covered by the protection scope of the present invention.
