Description
Technical Field
[0001] The present invention relates to the technical field of thermal paper production, and particularly to a punching machine for thermal paper production. Background Art
[0002] Thermal paper is also known as thermal fax paper, thermal recording paper, thermal copying paper, and also called heat-sensitive copying paper. Thermal paper is a processed paper, and its manufacturing principle is to coat a layer of "thermal coating" (thermal color-changing layer) on high-quality base paper. Although there are more than a dozen chemical drugs used in this color-changing layer, there are at least the following compounds: colorless dyes, and there are a wide variety of such dyes, and the most commonly used are fluorescent compounds; developers account for less than 20%, and commonly used ones include bisphenol and p-hydroxybenzoic acid; sensitizers account for less than 10%, which contain benzenesulfonamide compounds; fillers account for less than 50%, and commonly used ones include calcium carbonate (fine particles); adhesives account for less than 10%, such as polyvinyl acetate; stabilizers, such as dibenzoyl terephthalate; lubricants, etc. Therefore, the process is difficult and the technical requirements are high.
[0003] A punching machine for thermal paper production is generally used for punching thermal paper. During the punching process, the thermal paper is generally placed in the punching machine, and the punching head punches the thermal paper. However, during the punching process, since the thermal paper is relatively light, when the punching head completes punching and disengages from the inside of the thermal paper, it is easy to drive the top thermal paper to move, causing the thermal paper to shift, affecting the accuracy of subsequent punching. During the punching process, the paper scraps generated during punching will scatter on the machine, causing pollution and making it inconvenient for users to clean. Therefore, it is not convenient for users to use. Summary of the Invention

[0015] When the present invention limits and positions the thermosensitive paper to be punched at the top of the mobile box, the positioning mechanism can be used to fix and position the thermosensitive paper to be punched. The user can place the thermosensitive paper to be punched on the top of the mobile box. At this time, first, the driving hydraulic cylinder inside the installation bin is opened, so that the hydraulic cylinder drive shaft drives the limit baffle to move upward, so that the limit baffle limits the front end of the thermosensitive paper to be punched. Subsequently, the driving electric cylinder is opened, so that the driving electric cylinder drives the U-shaped connecting shaft and the blanking push plate to move towards the thermosensitive paper to be punched until the thermosensitive paper to be punched is pushed to fit with the limit baffle. At the same time, the positioning motor is opened, so that the left and right screw rods rotate. By the rotation of the left and right screw rods, the moving nuts at both ends will move closer to each other along the outer wall of the left and right screw rods. Under the movement of the moving nuts, the positioning slider and the connecting plate will move closer to each other at the same time, so that the two positioning clamping plates will move closer to each other. The two ends of the thermosensitive paper to be punched at the top of the mobile box are clamped and positioned by the two positioning clamping plates. Under the action of the limit baffle, the two positioning clamping plates and the blanking push plate, the thermosensitive paper to be punched can be horizontally placed on the mobile box, avoiding the deviation of the thermosensitive paper to be punched during the punching operation and causing punching errors; The present invention performs the conveying and punching operations on the thermosensitive paper to be punched through the feeding mechanism. When it is necessary to punch the thermosensitive paper fixed at the top of the mobile box, the driving motor at one end of the installation box can be opened to make the transmission lead screw rotate. Under the rotation of the transmission lead screw, the lead screw nut will move to the right along the outer wall of the transmission lead screw. At this time, under the movement of the lead screw nut, the moving slider and the mobile box will be synchronously driven to move to the right, so that it is convenient for the user to convey the thermosensitive paper fixed at the top of the mobile box to the bottom of the punching and impurity removing mechanism for punching operations. At the same time, when the mobile box moves, the limit wheel set at the bottom of the mobile box will slide along the limit chute at the top of the installation table. The movement of the mobile box is limited by the limit wheel set and the limit chute, increasing the movement stability of the mobile box, reducing the friction between the mobile box and the installation table, and reducing the wear of the bottom end of the mobile box; When the present invention is dealing with the punching operation of the punched thermal paper, the punching and impurity removing mechanism is used to perform the punching operation on the thermal paper. When the punched thermal paper moves to the bottom of the punching and impurity removing mechanism through the feeding mechanism, the second adjusting motor can be turned on to make the second ball screw rotate. The rotation of the second ball screw will drive the second adjusting nut to move downward along the outer wall of the second ball screw. The movement of the second adjusting nut will drive the lifting plate and the punching head to move downward synchronously, so as to perform the punching operation on the punched thermal paper by the downward movement of the punching head. When the punching head is performing the punching operation on the punched thermal paper, since the punching head is a cylindrical hollow tube, when the punching head cuts and punches the thermal paper, the paper scraps of the punched part of the thermal paper will remain in the tube of the punching head. At this time, the air pump is turned on, so that the air suction pipe sucks the paper scraps in the tube of the punching head into the exhaust pipe, and the paper scraps are discharged into the centralized box in the collection box through the exhaust pipe. The centralized box is used to centrally collect the paper scraps. When it is necessary to clean the paper scraps inside the centralized box, the centralized box can be taken out by pulling the handle, which is convenient for cleaning. Through the adsorption and centralized cleaning of the paper scraps, there will be no paper scraps during the punching operation of the thermal paper, and the punching operation environment will not be polluted. At the same time, during the punching operation, when the punching head moves downward for punching, the positioning pressing plate will also descend simultaneously. When the positioning pressing plate fits with the thermal paper, the thermal paper is flattened by the positioning pressing plate. When the punching head continues to punch downward, the limiting rod will be inserted into the slot, so as not to affect the punching head to continue punching downward. When the punching head finishes punching and moves upward, under the elastic force of the return spring, the positioning pressing plate will always fit with the surface of the thermal paper until the punching head disengages from the thermal paper, avoiding the punching head driving the thermal paper to move when the punching head is pulled out upward from the thermal paper, resulting in the deviation of the thermal paper; When the present invention is performing the punching operation on the thermal paper, the punching position of the punching head is adjusted through the punching adjustment mechanism. During the punching operation, when it is necessary to adjust the front and back punching positions of the punching head, the first adjusting motor can be turned on to make the first ball screw rotate. The rotation of the first ball screw will drive the first adjusting nut to move linearly back and forth along the outer wall of the first ball screw. The movement of the first adjusting nut will drive the moving column, the lifting plate and the punching head to move back and forth, so as to facilitate the user to adjust the front and back punching positions of the punching head. When it is necessary to adjust the left and right punching positions of the punching head, the third adjusting motor inside the lifting plate can be turned on to make the third ball screw rotate. The rotation of the third ball screw will drive the third adjusting nut to move linearly left and right along the outer wall of the third ball screw. Under the movement of the third adjusting nut, the adjusting slide plate, the connecting block and the punching head will be driven to move linearly left and right synchronously, which is convenient for the user to adjust the left and right punching positions of the punching head, increasing the adjustability of the device; After the present invention finishes punching the punching thermal paper, the punched thermal paper is moved to the top of the finished product conveying mechanism through the blanking mechanism, which is convenient for the next operation. When the punching thermal paper to be punched is moved from the feeding mechanism to the bottom of the punching and impurity removing mechanism and the punching is completed, the driving motor can be continuously turned on at this time to make the conveyor belt and the conveyor closer. At this time, the driving hydraulic cylinder is first opened to make the driving shaft of the hydraulic cylinder drive the limit baffle to move downward until the limit baffle moves into the installation bin, which does not affect the movement of the punched thermal paper. Subsequently, the driving electric cylinder is opened to make the U-shaped connecting shaft drive the blanking push plate to push the punched thermal paper onto the conveyor belt. At this time, the blanking motor is opened to make the conveying rod rotate, so that the conveyor belt conveys the punched thermal paper until it is conveyed to the top of the conveyor belt. At this time, the conveying motor is opened to make the driving rod rotate, so as to drive the conveyor belt to convey the punched thermal paper at the top for the conveying operation and complete the conveying of the finished product.

[0038] The present invention provides as Figures 1-13The shown thermal paper production punching machine includes an installation base plate 1. At the top of the installation base plate 1, there is an installation table 2. A limit chute 201 is opened at the top of the installation table 2. A feeding mechanism 3 is arranged at the top of the installation table 2. A moving box 306 is arranged at the top of the installation table 2. One end of the feeding mechanism 3 is equipped with a positioning mechanism 4. A to-be-punched thermal paper 5 is clamped at the top of the positioning mechanism 4. One end of the positioning mechanism 4 is equipped with a blanking mechanism 6. Punching adjustment mechanisms 7 are installed on both sides of the installation table 2. A punching and impurity removing mechanism 8 is installed at the top of the punching adjustment mechanism 7. A finished product conveying mechanism 9 is arranged at one end of the installation table 2; The positioning mechanism 4 includes a driving hydraulic cylinder 409 installed inside the moving box 306. A hydraulic cylinder driving shaft 410 is installed at the top of the driving hydraulic cylinder 409. The top of the hydraulic cylinder driving shaft 410 is connected to a limit baffle 411; The punching and impurity removing mechanism 8 includes an impurity removing box 801 installed at the top of the punching adjustment mechanism 7. A punching head 802 is installed at the bottom of the impurity removing box 801. A connector 803 is sleeved on the top of the punching head 802. An air extraction pipe 804 is installed at the top of the connector 803. The top of the air extraction pipe 804 is connected to an air extraction pump 805. A positioning pressing plate 810 is also installed at the bottom of the impurity removing box 801. When the present invention is in use, the user can place the to-be-punched thermal paper 5 on the top of the moving box 306. At this time, first, by turning on the driving hydraulic cylinder 409 inside the installation bin 401, the hydraulic cylinder driving shaft 410 drives the limit baffle 411 to move upward, so that the limit baffle 411 limits the front end of the to-be-punched thermal paper 5. Subsequently, by turning on the driving electric cylinder 602, the driving electric cylinder 602 drives the U-shaped connecting shaft 603 and the blanking push plate 604 to move towards the to-be-punched thermal paper 5 until the to-be-punched thermal paper 5 is pushed to fit with the limit baffle 411. At the same time, by turning on the positioning motor 402, the left and right threaded screw 403 rotates. Due to the rotation of the left and right threaded screw 403, the moving nuts 404 at both ends move towards each other along the outer wall of the left and right threaded screw 403. Under the movement of the moving nuts 404, the positioning sliders 405 and the connecting plate 406 move towards each other simultaneously, so that the two groups of positioning clamping plates 408 move towards each other. The two ends of the to-be-punched thermal paper 5 on the top of the moving box 306 are clamped and positioned by the two groups of positioning clamping plates 408. Under the action of the limit baffle 411, the two groups of positioning clamping plates 408 and the blanking push plate 604, the to-be-punched thermal paper 5 can be horizontally placed on the moving box 306, avoiding the deviation of the to-be-punched thermal paper 5 during the punching operation and causing punching errors. When it is necessary to punch the to-be-punched thermal paper 5 fixed on the top of the moving box 306, the driving motor 302 at one end of the installation box 301 can be turned on to make the transmission screw rod 303 rotate. Under the rotation of the transmission screw rod 303, the screw nut 304 is driven to move to the right along the outer wall of the transmission screw rod 303. At this time, under the movement of the screw nut 304,It will synchronously drive the moving slider 305 and the moving box 306 to move to the right, so as to facilitate the user to transport the to-be-punched thermal paper 5 fixed at the top of the moving box 306 to the bottom of the punching and impurity-removing mechanism 8 for punching operations. At the same time, when the moving box 306 moves, the limiting wheel set 307 at the bottom of the moving box 306 will slide along the limiting chute 201 at the top of the mounting table 2. The movement of the moving box 306 is limited by the limiting wheel set 307 and the limiting chute 201, which increases the movement stability of the moving box 306. At the same time, it also reduces the friction between the moving box 306 and the mounting table 2 and reduces the wear of the bottom end of the moving box 306. When the to-be-punched thermal paper 5 is moved to the bottom of the punching and impurity-removing mechanism 8 through the feeding mechanism 3, the second adjusting motor 705 can be turned on to make the second ball screw 706 rotate. The rotation of the second ball screw 706 will drive the second adjusting nut 707 to move downward along the outer wall of the second ball screw 706. The movement of the second adjusting nut 707 will drive the lifting plate 708 and the punching head 802 to move downward synchronously. Thus, the punching head 802 moves downward to perform punching operations on the to-be-punched thermal paper 5. When the punching head 802 performs punching operations on the to-be-punched thermal paper 5, since the punching head 802 is a cylindrical hollow tube, when the punching head 802 cuts and punches the thermal paper, the paper scraps of the punched part of the thermal paper will remain in the tube of the punching head 802. At this time, by turning on the air extraction pump 805, the air extraction pipe 804 will extract the paper scraps in the tube of the punching head 802 into the exhaust pipe 806, and the paper scraps will be discharged into the centralized box 808 in the collection box 807 through the exhaust pipe 806. The centralized box 808 centrally collects the paper scraps. When it is necessary to clean the paper scraps inside the centralized box 808, the centralized box 808 can be taken out by pulling the handle 809, which is convenient for cleaning. Through the adsorption and centralized cleaning of the paper scraps, there will be no paper scraps during the punching operation of the thermal paper, and the punching operation environment will not be polluted. At the same time, during the punching operation, when the punching head 802 moves downward for punching, the positioning pressing plate 810 will also descend simultaneously. When the positioning pressing plate 810 is in contact with the thermal paper, the thermal paper is flattened by the positioning pressing plate 810. When the punching head 802 continues to punch downward, the limiting rod 813 will be inserted into the slot 814, so as not to affect the punching head 802 to continue punching downward. When the punching head 802 finishes punching and moves upward, under the elastic force of the reset spring 811, the positioning pressing plate 810 will always be in contact with the surface of the thermal paper until the punching head 802 is separated from the thermal paper, avoiding the punching head 802 driving the thermal paper to move and causing the thermal paper to shift when the punching head 802 is pulled out upward from the thermal paper. During the punching operation process, when it is necessary to adjust the front and rear punching positions of the punching head 802, the first adjusting motor 701 can be turned on to make the first ball screw 702 rotate.The rotation of the first ball screw 702 drives the first adjusting nut 703 to move linearly back and forth along the outer wall of the first ball screw 702. The movement of the first adjusting nut 703 drives the moving column 704, the lifting plate 708 and the punching head 802 to move back and forth, facilitating the user to adjust the front and back punching positions of the punching head 802. When it is necessary to adjust the left and right punching positions of the punching head 802, the third adjusting motor 709 inside the lifting plate 708 can be turned on to make the third ball screw 710 rotate. The rotation of the third ball screw 710 drives the third adjusting nut 711 to move linearly left and right along the outer wall of the third ball screw 710. Under the movement of the third adjusting nut 711, the adjusting slide plate 712, the connecting block 713 and the punching head 802 are synchronously driven to move linearly left and right, facilitating the user to adjust the left and right punching positions of the punching head 802, increasing the adjustability of the device. When the to-be-punched thermal paper 5 is moved by the feeding mechanism 3 to the bottom of the punching and impurity-removing mechanism 8 and the punching is completed, the driving motor 302 can be continuously turned on at this time to make the conveyor belt 609 and the conveyor 904 approach. First, the driving hydraulic cylinder 409 is turned on to make the hydraulic cylinder drive shaft 410 drive the limit baffle 411 to move downward until the limit baffle 411 moves into the installation bin 401, without affecting the movement of the punched thermal paper. Subsequently, the driving electric cylinder 602 is turned on to make the U-shaped connecting shaft 603 drive the blanking push plate 604 to push the punched thermal paper onto the conveyor belt 609. At this time, the blanking motor 607 is turned on to make the conveying rod 608 rotate, so that the conveyor belt 609 conveys the punched thermal paper until it is conveyed to the top of the conveyor 904. At this time, the conveying motor 902 is turned on to make the driving rod 903 rotate, thereby driving the conveyor 904 to convey the thermal paper with punched holes at the top, completing the conveying of the finished product.,
[0039] In this solution, the feeding mechanism 3 is used to convey and punch the heat-sensitive paper 5 to be punched. The feeding mechanism 3 includes an installation box 301 installed at the top end of the installation table 2. A driving motor 302 is installed at one end of the installation box 301. A transmission lead screw 303 is installed at one end of the driving motor 302. A lead screw nut 304 is sleeved on the outer wall of the transmission lead screw 303. A moving slider 305 is installed on the outer wall of the lead screw nut 304. A limiting wheel set 307 is installed at the bottom end of the moving box 306. A limiting shaft 308 is movably inserted into the moving slider 305 at one end of the moving box 306 away from the lead screw nut 304. When punching the heat-sensitive paper 5 fixed at the top end of the moving box 306 is required, the driving motor 302 at one end of the installation box 301 can be turned on, so that the transmission lead screw 303 rotates. Under the rotation of the transmission lead screw 303, the lead screw nut 304 will be driven to move to the right along the outer wall of the transmission lead screw 303. At this time, under the movement of the lead screw nut 304, the moving slider 305 and the moving box 306 will be synchronously driven to move to the right, so as to facilitate the user to convey the heat-sensitive paper 5 fixed at the top end of the moving box 306 to the bottom end of the punching and impurity-removing mechanism 8 for punching operation. At the same time, when the moving box 306 moves, the limiting wheel set 307 at the bottom end of the moving box 306 will slide along the limiting chute 201 at the top end of the installation table 2. The movement of the moving box 306 is limited by the limiting wheel set 307 and the limiting chute 201, which increases the movement stability of the moving box 306, reduces the friction between the moving box 306 and the installation table 2, and reduces the wear of the bottom end of the moving box 306.
[0040] When this solution needs to limit and position the thermosensitive paper 5 to be punched at the top of the moving box 306, the positioning mechanism 4 can be used to fix and position the thermosensitive paper 5 to be punched. The positioning mechanism 4 further includes an installation bin 401 opened inside the moving box 306. A positioning motor 402 is installed inside the installation bin 401. A left-right screw 403 is installed at one end of the positioning motor 402. Moving nuts 404 are sleeved on the outer walls of both ends of the left-right screw 403. A positioning slider 405 is installed on the outer wall of the moving nut 404. A connecting plate 406 is installed at the top of the positioning slider 405. A limiting groove 407 is opened at the top of the moving box 306. A positioning clamping plate 408 is installed at the top of the connecting plate 406. Among them, the user can place the thermosensitive paper 5 to be punched on the top of the moving box 306. At this time, first, by opening the driving hydraulic cylinder 409 inside the installation bin 401, the hydraulic cylinder drive shaft 410 drives the limiting baffle 411 to move upward, so that the limiting baffle 411 limits the front end of the thermosensitive paper 5 to be punched. Subsequently, by opening the driving electric cylinder 602, the driving electric cylinder 602 drives the U-shaped connecting shaft 603 and the blanking push plate 604 to move towards the thermosensitive paper 5 to be punched until the thermosensitive paper 5 to be punched is pushed to fit with the limiting baffle 411. At the same time, by opening the positioning motor 402, the left-right screw 403 rotates. The rotation of the left-right screw 403 drives the moving nuts 404 at both ends to move closer to each other along the outer wall of the left-right screw 403. Under the movement of the moving nuts 404, the positioning slider 405 and the connecting plate 406 will move closer to each other simultaneously, so that the two positioning clamping plates 408 move closer to each other. The two ends of the thermosensitive paper 5 to be punched at the top of the moving box 306 are clamped and positioned by the two positioning clamping plates 408. Under the action of the limiting baffle 411, the two positioning clamping plates 408 and the blanking push plate 604, the thermosensitive paper 5 to be punched can be horizontally placed on the moving box 306, avoiding the deviation of the thermosensitive paper 5 to be punched during the punching operation and causing punching errors.
[0041] After the punching of the punched thermal paper 5 is completed in this solution, the punched thermal paper is moved to the top of the finished product conveying mechanism 9 by the blanking mechanism 6, which facilitates other operations. The blanking mechanism 6 includes a mounting plate 601 installed at the top of the moving box 306. A driving electric cylinder 602 is installed at the top of the mounting plate 601. One end of the driving electric cylinder 602 is connected to a U-shaped connecting shaft 603. One end of the U-shaped connecting shaft 603 is connected to a blanking push plate 604. A fixed frame 605 is installed at one end of the moving box 306. A support plate 606 is installed at the bottom of the fixed frame 605. A blanking motor 607 is installed on one side of the fixed frame 605. One end of the blanking motor 607 is installed with a conveying rod 608. A conveyor belt 609 is engaged with the outer wall of the conveying rod 608. When the punched thermal paper 5 is moved from the feeding mechanism 3 to the bottom of the punching and impurity removing mechanism 8 and the punching is completed, at this time, the driving motor 302 can be continuously turned on to make the conveyor belt 609 approach the conveyor belt 904. At this time, first, the driving hydraulic cylinder 409 is turned on, so that the hydraulic cylinder drive shaft 410 drives the limit baffle 411 to move downward until the limit baffle 411 moves into the installation bin 401, which does not affect the movement of the punched thermal paper. Subsequently, the driving electric cylinder 602 is turned on, so that the U-shaped connecting shaft 603 drives the blanking push plate 604 to push the punched thermal paper onto the conveyor belt 609. At this time, the blanking motor 607 is turned on, so that the conveying rod 608 rotates, thereby making the conveyor belt 609 convey the punched thermal paper until it is conveyed to the top of the conveyor belt 904.
[0042] When this solution performs the punching operation on thermal paper, the punching position of the punching head 802 is adjusted by the punching adjustment mechanism 7. The punching adjustment mechanism 7 includes a first adjustment motor 701 installed at one end of the installation table 2. One end of the first adjustment motor 701 is equipped with a first ball screw 702. The outer wall of the first ball screw 702 is sleeved with a first adjustment nut 703. The outer wall of the first adjustment nut 703 is installed with a moving column 704. The top of the moving column 704 is installed with a second adjustment motor 705. The bottom of the second adjustment motor 705 is installed with a second ball screw 706. The outer wall of the second ball screw 706 is sleeved with a second adjustment nut 707. The outer wall of the second adjustment nut 707 is installed with a lifting plate 708. A pulley groove 816 is opened at the top of the lifting plate 708. A third adjustment motor 709 is installed inside the lifting plate 708. One end of the third adjustment motor 709 is installed with a third ball screw 710. The outer wall of the third ball screw 710 is sleeved with a third adjustment nut 711. The outer wall of the third adjustment nut 711 is installed with an adjustment slide plate 712. Connecting blocks 713 are fixed at both ends of the adjustment slide plate 712. When the thermal paper 5 to be punched moves to the bottom of the punching and impurity removing mechanism 8 through the feeding mechanism 3, the second adjustment motor 705 can be turned on, so that the second ball screw 706 rotates. The rotation of the second ball screw 706 drives the second adjustment nut 707 to move downward along the outer wall of the second ball screw 706. The movement of the second adjustment nut 707 drives the lifting plate 708 and the punching head 802 to move downward synchronously, so as to perform the punching operation on the thermal paper 5 to be punched by the downward movement of the punching head 802. During the punching operation, when it is necessary to adjust the front and rear punching positions of the punching head 802, the first adjustment motor 701 can be turned on, so that the first ball screw 702 rotates. The rotation of the first ball screw 702 drives the first adjustment nut 703 to move linearly back and forth along the outer wall of the first ball screw 702. The movement of the first adjustment nut 703 drives the moving column 704, the lifting plate 708 and the punching head 802 to move back and forth, so as to facilitate the user to adjust the front and rear punching positions of the punching head 802. When it is necessary to adjust the left and right punching positions of the punching head 802, the third adjustment motor 709 inside the lifting plate 708 can be turned on, so that the third ball screw 710 rotates. The rotation of the third ball screw 710 drives the third adjustment nut 711 to move linearly left and right along the outer wall of the third ball screw 710. Under the movement of the third adjustment nut 711, the adjustment slide plate 712, the connecting blocks 713 and the punching head 802 are synchronously driven to move linearly left and right, which is convenient for the user to adjust the left and right punching positions of the punching head 802, increasing the adjustability of the device.
[0043] When this solution is used for the punching operation on the heat-sensitive paper 5, the punching and impurity removal mechanism 8 performs the punching operation on the heat-sensitive paper. The punching and impurity removal mechanism 8 further includes an exhaust pipe 806 installed at one end of the air extraction pump 805. A collection box 807 is installed at the bottom end of the exhaust pipe 806. A centralized box 808 is arranged inside the collection box 807. A handle 809 is installed at one end of the centralized box 808. A return spring 811 is installed at the top end of the positioning pressing plate 810. Spring pressing pieces 812 are installed at both the upper and lower ends of the return spring 811. A limiting rod 813 is installed inside the return spring 811. A slot 814 is opened at the bottom end of the impurity removal box 801. A limiting pulley 815 is installed at the bottom end of the air extraction pump 805. When the punching head 802 performs the punching operation on the heat-sensitive paper 5 to be punched, since the punching head 802 is a cylindrical hollow tube, when the punching head 802 cuts and punches the heat-sensitive paper, some of the paper scraps of the punched part of the heat-sensitive paper will remain inside the tube of the punching head 802. At this time, by turning on the air extraction pump 805, the air extraction pipe 804 sucks the paper scraps inside the tube of the punching head 802 into the exhaust pipe 806, and the paper scraps are discharged into the centralized box 808 in the collection box 807 through the exhaust pipe 806. The centralized box 808 centrally collects the paper scraps. When it is necessary to clean the paper scraps inside the centralized box 808, the centralized box 808 can be taken out by pulling the handle 809, which is convenient for cleaning. Through the adsorption and centralized cleaning of the paper scraps, there will be no paper scraps during the punching operation on the heat-sensitive paper, and the punching operation environment will not be polluted. At the same time, during the punching operation, when the punching head 802 moves downward for punching, the positioning pressing plate 810 will also descend simultaneously. When the positioning pressing plate 810 is in contact with the heat-sensitive paper, the heat-sensitive paper is flattened by the positioning pressing plate 810. When the punching head 802 continues to punch downward, the limiting rod 813 will be inserted into the slot 814, so as not to affect the punching head 802 continuing to punch downward. When the punching head 802 finishes punching and moves upward, under the elastic force of the return spring 811, the positioning pressing plate 810 will always be in contact with the surface of the heat-sensitive paper until the punching head 802 disengages from the heat-sensitive paper, preventing the punching head 802 from driving the heat-sensitive paper to move and causing the heat-sensitive paper to shift when the punching head 802 is pulled out upward and disengaged from the heat-sensitive paper.
[0044] When the present solution conveys the punched thermal paper, the conveying operation is carried out through the finished product conveying mechanism 9. The finished product conveying mechanism 9 includes a mounting bracket 901 installed at one end of the mounting base plate 1. One end of the mounting bracket 901 is installed with a conveying motor 902. One end of the conveying motor 902 is installed with a driving rod 903. The outer wall of the driving rod 903 is engaged with a conveyor belt 904. One end of the conveyor belt 904 away from the driving rod 903 is engaged with a driven rod 905. When the conveyor belt 609 conveys the punched thermal paper to the top of the conveyor belt 904, by turning on the conveying motor 902, the driving rod 903 rotates, thereby driving the conveyor belt 904 to convey the punched thermal paper at the top, and completing the conveying of the finished product.
