Description

Technical Field

[0001] The invention relates to the technical field of thermal paper winding, and in particular to a winding device for thermal paper production and a use method thereof. Background Art

[0002] Thermal paper is also known as thermal fax paper, thermal recording paper, and thermal copy paper. Thermal paper is a processed paper. Its manufacturing principle is to coat a layer of "thermal coating" (thermal color-changing layer) on high-quality base paper. After the thermal paper is produced, it needs to be rolled up by a rolling device for centralized transportation.

[0003] The prior art discloses a small roll thermal paper slitting machine and a slitting method thereof with publication number CN117067273A. The drive mechanism is used to drive the thermal paper placement box to continue to move downward, so that a plurality of cutting blades move downward, thereby cutting the thermal paper roll placed inside the limiting cavity in sections. After the thermal paper roll is cut, the hydraulic telescopic rod is extended to lift up one side of the cutting mold, so that the cut thermal paper roll is slid and collected through a sliding plate, thereby realizing a slitting process, which can not only achieve the slitting effect of the thermal paper roll, but also has a high automation effect and a good cutting and separation effect.

DETAILED DESCRIPTION

[0034] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] like Figure 1-9A winding device for thermal paper production shown in the figure comprises a slitting machine 1 and a winding mechanism 2 arranged on the slitting machine 1. The winding mechanism 2 is mainly composed of a motor, a winding roller and a positioning cylinder and other structures. It is a mature technology in the prior art and will not be described in detail here. A feeding table 3 is arranged next to the winding mechanism 2. A pair of fixed plates 4 are fixedly connected to the middle position of the top of the feeding table 3. A pair of driving rollers 5 are rotatably connected between the fixed plates 4. A conveyor belt 6 is drivingly connected between the driving rollers 5. A plurality of semicircular arc grooves 7 are equidistantly provided on the conveyor belt 6. A driving motor 8 is fixedly connected to the side wall of the fixed plate 4. The output end of the driving motor 8 passes through the fixed plate 4 and is fixedly connected to the side wall of one of the driving rollers 5. A feeding component for feeding and pushing out the thermal paper roll on the winding roller is arranged on the top of the feeding table 3.

[0037] The feeding assembly includes a storage hopper 9, which is fixedly connected to the unloading platform 3 through four supporting legs 10. A pair of support plates 11 are fixedly connected to the top of the unloading platform 3 and below the storage hopper 9. A semicircular arc seat 12 is fixedly connected between the tops of the support plates 11. A semicircular groove 13 is provided at the bottom of the storage hopper 9 close to the fixed plate 4. A pushing groove 14 is provided through the top of the semicircular arc seat 12. A pushing seat 15 is slidably connected between the support plates 11. A pushing plate 16 is rotatably connected to the inner side of the pushing seat 15. The bottom end of the side wall of the pushing plate 16 is fixedly connected to a plate 17, and the storage hopper 9 is provided with a side wall that is away from the semicircular groove 13. The upper groove 18 matched with the push plate 16 can avoid affecting the normal sliding of the push plate 16 through the setting of the upper groove 18, and at the same time can limit the sliding position of the winding drum in the storage hopper 9, so as to avoid the push plate 16 pushing the winding drum in the storage hopper 9 to move when resetting. A driving mechanism for driving the push seat 15 to move is provided on the unloading platform 3, and the bottom of the push plate 17 is against the top of the push seat 15, and an upper spring 19 is fixedly connected between the side wall of the push plate 17 and the top of the push seat 15. Through the setting of the upper spring 19, after the push plate 16 is moved out from under the winding drum, the push plate 17 and the push plate 16 can be quickly pulled to flip and reset;

[0038] The driving mechanism includes a loading motor 20, a pair of lower plates 21 are fixedly connected to the bottom of the unloading platform 3, and a threaded rod 22 is rotatably connected between the lower plates 21. The loading motor 20 is fixedly connected to one of the side walls of the lower plates 21, and the output end of the loading motor 20 passes through the lower plate 21 and is fixedly connected to the side wall of the threaded rod 22, and a driving block 23 is threadedly connected to the threaded rod 22, and a lower groove 24 is provided at the top of the unloading platform 3 and below the semicircular arc seat 12, and an upper L-shaped rod 25 is fixedly connected to the bottom of the push plate 16 and passes through the lower groove 24, and a push plate 26 is fixedly connected to the other end of the upper L-shaped rod 25 and at a position corresponding to the driving block 23, and a pair of reset springs 27 are fixedly connected between the side walls of the upper L-shaped rod 25 and the fixed plate 4. Through the setting of the reset springs 27, it is convenient to push the upper L-shaped rod 25 to reset when resetting, and a unloading assembly for receiving the thermal paper roll pushed down from the winding roller is provided at the top of the unloading platform 3 and away from the side of the loading assembly;

[0039] Before slitting and winding the thermal paper, place the winding drum neatly in the storage hopper 9. At this time, the lowest winding drum will fall into the semi-circular arc seat 12 under its own gravity. Then, during the slitting and winding process of the thermal paper, when the wound thermal paper roll needs to be taken out, first take the winding roller out of the winding mechanism 2 and put it into the semi-circular arc groove 7 on the conveyor belt 6 (it should be noted here that the winding roller just taken out needs to be put into the semi-circular arc groove 7 close to the side of the winding mechanism 2, and the winding roller with the replaced drum is located in the front semi-circular arc groove 7, which is convenient for taking and placing the winding roller in sequence), then cut the wound thermal paper, and stick the cut thermal paper to the wound thermal paper, and then put The winding roller with the winding drum is placed on the winding mechanism 2, and the cut thermal paper is wound onto the winding roller, and then the winding mechanism 2 is controlled to start to wind up the cut thermal paper, and at the same time, the driving mechanism and the driving motor 8 are controlled to start, so that one of the transmission rollers 5 is driven to rotate by the driving motor 8, and then the conveyor belt 6 is driven between the two transmission rollers 5, and the other transmission roller 5 is driven to rotate, so that the winding roller just placed is moved to the side of the semicircular arc seat 12, and then the driving motor 8 stops running (it should be noted here that the driving motor 8 can be controlled by the timing controller to control the start time of each time, so as to accurately move the winding roller to the side of the semicircular arc seat 12);

[0040] At the same time, by controlling the feeding motor 20 to start and drive the threaded rod 22 to rotate, the threaded driving block 23 is driven to move, and the threaded sliding block 36 is driven to rotate, thereby driving the unloading assembly to operate, so that the unloading rod 29 moves to the side of the winding roller, and then under the continued drive of the feeding motor 20, the driving block 23 will move to the side of the push plate 26 of the side wall of the upper L-shaped rod 25, so that the continued movement of the driving block 23 will push the push plate 26 and the upper L-shaped rod 25 to move, thereby driving the push seat 15 to slide between the support plate 11 and gradually compressing the return spring 2 7, and at the same time, it will drive the push plate 16 on the push seat 15 to move in the push slot 14. Since one side of the push plate 16 is restrained by the abutment plate 17, when the push plate 16 passes through the upper slot 18 and enters the storage hopper 9, it will push the multiple winding drums in the semicircular arc seat 12 to move, and then the winding drum on the semicircular arc seat 12 will pass through the winding roller to squeeze the thermal paper roll on the winding roller to move (the winding roller is resisted by the unloading rod 29 and cannot move at this time), so as to push the thermal paper roll on the winding roller onto the unloading rod 29, so as to push out the wound thermal paper roll, and push the new winding drum onto the winding roller;

[0041] Then the feeding motor 20 is controlled to drive in reverse to drive the feeding assembly and the unloading assembly to move in reverse for resetting. When the winding drum on the semicircular arc seat 12 is pushed away, the winding drum in the storage hopper 9 will slide downward under its own gravity and fall onto the semicircular arc seat 12. Therefore, when the feeding assembly is reset, since there is no restriction on the other side of the push plate 16, the push plate 16 will be squeezed by the winding drum on the semicircular arc seat 12 to flip over, and at the same time drive the push plate 17 to flip over and stretch the upper spring 19, so that the push plate 16 flips to the bottom of the winding drum. Then, when the push plate 16 moves out from under the winding drum to release the squeezing, the push plate 17 and the push plate 16 will be pulled to flip and reset under the elastic force of the upper spring 19.

[0042] In order to improve the stability of the device during operation, a guide rod 28 is fixedly connected between the lower plate 21, and the guide rod 28 passes through the inner wall of the driving block 23, and the guide rod 28 passes through the inner wall of the sliding block 36. Through the setting of the guide rod 28, it can play a guiding role in the process of the threaded rod 22 rotating to drive the driving block 23 and the sliding block 36 to move, avoiding the sliding block 36 and the driving block 23 from rotating with the threaded rod 22, thereby improving the stability of the device during operation.

[0043] In order to automatically collect the pushed out thermal paper roll into the material box, the unloading component includes a unloading rod 29, an L-shaped frame 30 is fixedly connected to the top of the unloading platform 3 and away from the side of the loading component, and an inclined plate 43 is fixedly connected to the inner side of the L-shaped frame 30. The inclined plate 43 is arranged to facilitate the falling thermal paper roll to slide into the material box. The unloading rod 29 penetrates and is slidably connected to the side wall of the L-shaped frame 30, and a fixed seat 31 is fixedly connected to the outer wall of the L-shaped frame 30 and located below the unloading rod 29. A roller 32 is rotatably connected to the inner side of the fixed seat 31, and the roller 32 can guide the sliding of the pull rope 33. The unloading rod 29 is fixedly connected to the end away from the loading component with a pull rope 33, and the L-shaped frame 30 is fixedly connected to the side wall of the L-shaped frame 30. The outer wall is fixedly connected with a side plate 34, and the side wall of the side plate 34 is slidably connected with a lower L-shaped rod 35 and is arranged through the top of the unloading platform 3. The other end of the pull rope 33 passes through the outer wall of the roller 32 and is fixedly connected to the top of the lower L-shaped rod 35. The threaded rod 22 is threadedly connected with a sliding block 36. An extrusion spring 40 is fixedly connected between the outer wall of the L-shaped frame 30 and the outer wall of the unloading rod 29. The extrusion spring 40 facilitates the unloading rod 29 to be reset under the elastic force of the extrusion spring 40 when the sliding block 36 is reset and the thrust on the lower L-shaped rod 35 is released. The side wall of the unloading platform 3 and the side of the inclined plate 43 are fixedly connected with a placing table 41 for placing a material box, and the placing table 41 facilitates the placement of the material box;

[0044] Before winding, the material box is placed on the placement table 41, and then when the driving mechanism drives the feeding assembly to operate, the feeding motor 20 drives the threaded rod 22 to rotate, thereby driving the threaded sliding block 36 to rotate, and then driving the telescopic block 38 to move, so that the lower L-shaped rod 35 is driven to move at the same time under the thrust of the lower spring 39, and the pull rope 33 is pulled to move, and then under the guidance of the roller 32, the pull rope 33 is used to pull the material discharge rod 29 to move on the L-shaped frame 30, and the extrusion spring 40 is gradually compressed to move the material discharge rod 29 to a position aligned with the winding roller, and then under the continued drive of the driving mechanism, the telescopic block 38 is driven to slide on the inner side of the telescopic slot 37, and gradually. The lower spring 39 is gradually compressed, and at the same time, the feeding assembly is driven to work, thereby pushing the thermal paper roll wound on the winding roller to the unloading rod 29, and the unloading rod 29 can resist the winding roller to prevent the winding roller from sliding during the pushing process and affecting the normal operation of the device. Finally, after the operation of the feeding assembly is completed, the driving mechanism can be controlled to drive the feeding assembly and the unloading assembly to reset, thereby gradually retracting the unloading rod 29. At this time, the inner side of the L-shaped frame 30 will resist the thermal paper roll, so that the thermal paper rolls inserted on the unloading rod 29 can be pushed out one by one, and then fall onto the inclined plate 43, and then fall into the material box below under its own gravity, thereby realizing the automatic collection of the thermal paper rolls and further improving the convenience of the device.

[0045] In order to avoid hindering the continued movement of the sliding block 36 after the unloading rod 29 is pushed into place, a telescopic groove 37 is opened on the side wall of the lower L-shaped rod 35, and the side wall of the sliding block 36 is fixedly connected with a telescopic block 38, and the telescopic block 38 is slidably connected to the inner side of the telescopic groove 37, and a lower spring 39 is fixedly connected between the side wall of the telescopic block 38 and the inner side of the telescopic groove 37. When the sliding block 36 pushes the lower L-shaped rod 35 to pull the unloading rod 29 to dock with the winding roller, the sliding of the lower L-shaped rod 35 on the side plate 34 is restricted. Therefore, under the continued drive of the driving mechanism, the sliding block 36 will be driven to move, thereby driving the telescopic block 38 to slide on the inner side of the telescopic groove 37 and gradually compressing the lower spring 39, so as not to affect the continued movement of the sliding block 36, thereby ensuring the normal operation of the loading assembly.

[0046] In order to limit the moving position of the winding roller, a limit plate 42 for limiting the sliding position of the winding roller is fixedly connected to the top of the fixed plate 4. By setting the limit plate 42, the position of the winding roller on the conveyor belt 6 can be limited, thereby ensuring that the position of the winding roller will not shift when it moves to the side of the unloading rod 29, affecting the normal operation of the subsequent unloading components.
