Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a splicing paper slitting machine with an anti-wrinkle structure, based on... Figure 1 and Figure 3 As shown, mounting seats 2 are provided on the outer sides of the symmetrically opened grooves on the front and back sides of the frame 1. An unwinding mechanism is provided between the symmetrically arranged mounting seats 2 on one side. Through the unwinding mechanism, the unwinding speed of the feed paper body 8 can be controlled according to the winding speed during unwinding and conveying, so that the tension of the feed paper body 8 is relatively stable during conveying. The unwinding mechanism includes an unwinding motor 3, an unwinding shaft 4, and a first support bearing 5. The unwinding motor 3 is installed inside the mounting seat 2 on the back side. The unwinding motor 3 is detachably connected to one end of the unwinding shaft 4 through a coupling. The other side of the unwinding shaft 4 is detachably connected to the first support bearing 5. The lower end of the first support bearing 5 is connected to the first self-locking slide rail 6 installed inside the corresponding mounting seat 2. At the same time, a support base 7 is provided below the unwinding shaft 4. The support base 7 is connected to the frame 1 through an electric telescopic rod. The feed paper body 8 is wound around the middle upper part of the support base 7 outside the unwinding shaft 4.

[0022] In use, the paper body 8 is wound around the outside of the unwinding shaft 4. Then, one end of the unwinding shaft 4 is connected to the output end of the unwinding motor 3 through a coupling. At the same time, the electric telescopic rod is activated to push the support base 7 upward to support the unwinding shaft 4, so that the other end of the unwinding shaft 4 is located in the middle of the first support bearing 5. Then, the first support bearing 5 is moved on the first self-locking slide rail 6 to connect with the other end of the unwinding shaft 4, thereby completing the placement and unwinding of the paper body 8.

[0023] according to Figure 1 , Figure 3 and Figure 5As shown, a winding mechanism is provided between the symmetrically arranged mounting bases 2 on the other side. The winding mechanism includes a winding motor 16, an upper winding shaft 17, and a lower winding shaft 23. The winding motor 16 is installed inside the mounting base 2 on the other side of the back. The winding motor 16 is detachably connected to one end of the upper winding shaft 17 via a coupling. The other end of the upper winding shaft 17 is detachably connected to a second support bearing 18. The lower end of the second support bearing 18 is connected to a second self-locking slide rail 19 installed inside the corresponding mounting base 2. Simultaneously, upper winding drums 20 are symmetrically arranged outside the upper winding shaft 17, and the lower winding shaft 23 is located below the upper winding shaft 17. A lower winding drum 24 is located outside the lower winding shaft 23, in the middle of the upper winding drum 20. The upper take-up drum 20 and the lower take-up drum 24 facilitate the winding of the slit splice paper body 8. At the same time, both ends of the lower take-up shaft 23 are connected to the first positioning bearing 102 and the second positioning bearing 103 respectively provided on the frame 1. One end of the lower take-up shaft 23 passes through the first positioning bearing 102 and extends to the outside of the frame 1. The connecting gear 22 provided on the lower take-up shaft 23 meshes with the transmission gear 21 provided on the upper take-up shaft 17. Through the meshing of the connecting gear 22 and the transmission gear 21, the lower take-up shaft 23 can also rotate synchronously when the upper take-up shaft 17 rotates. This allows the upper take-up drum 20 and the lower take-up drum 24 to synchronously wind the corresponding splice paper body 8, improving the practicality of use.

[0024] In use, the two ends of the slit paper body 8 are connected to the corresponding upper take-up drum 20, and the middle end of the slit paper body 8 is connected to the lower take-up drum 24. Then, the take-up motor 16 drives the upper take-up shaft 17 and the upper take-up drum 20 to rotate through the coupling, thus winding up the two ends of the slit paper body 8. Next, the transmission gear 21 drives the connecting gear 22 to rotate, which in turn drives the lower take-up shaft 23 and the lower take-up drum 24 to rotate, thereby winding up the middle end of the slit paper body. When the main body 8 is being wound up and needs to be disassembled, the second support bearing 18 is moved to separate one end of the upper take-up shaft 17. Then, the upper take-up drum 20 is moved to separate from the upper take-up shaft 17, thereby allowing the upper take-up shaft 17 to be disassembled and replaced after winding. At the same time, the lower take-up shaft 23 is moved to separate from the second positioning bearing 103. Then, the lower take-up drum 24 is moved to separate from the lower take-up shaft 23, thereby allowing the lower take-up drum 24 to be disassembled and replaced after winding.

[0025] according to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the frame 1, located between the unwinding mechanism and the rewinding mechanism, is sequentially equipped with a first guide assembly 9, a tensioning assembly 10, a leveling mechanism, a third guide assembly 13, and a fourth guide assembly 14. The first guide assembly 9 includes an electric heating shaft 901, a heat-conducting cylinder 902, a limiting plate 903, and a positioning threaded block 904. The heat-conducting cylinder 902 is located on the outside of the electric heating shaft 901. Heat is generated by the electric heating shaft 901 and is transferred to the paper receiving body 8 through the heat-conducting cylinder 902. This allows the paper receiving body 8 to maintain a flat shape and avoid wrinkles under the action of heat. The limiting plates 903 are symmetrically arranged on both sides of the heat-conducting cylinder 902. The limiting plates 903 are used to guide the paper receiving body 8. The conveying position is limited to prevent the paper body 8 from shifting during conveying. At the same time, the two ends of the electric heating shaft 901 are threadedly connected to the outer side of the limiting plate 903 with positioning thread blocks 904. The positioning thread blocks 904 facilitate the limiting of the heat conduction cylinder 902 and the limiting plate 903, improving the stability during use. The fourth guide component 14 is located above the third guide component 13 on the side away from the leveling mechanism. The third guide component 13 facilitates the guidance and conveying of the waste strips generated during slitting. The fourth guide component 14 is symmetrically arranged with slitting blades 15 on the side close to the third guide component 13. The slitting blades 15 have a U-shaped structure and slit the paper body 8.

[0026] To further explain, the structures of the tensioning assembly 10, the third guide assembly 13, and the fourth guide assembly 14 are the same as those of the first guide assembly 9. The tensioning assembly 10 is connected to the electric linear guide rails 101 symmetrically arranged on both sides of the frame 1. The tensioning assembly 10 is moved by the electric linear guide rails 101, which facilitates the adjustment of the tension during the feeding of the receiving paper body 8, improves the tension of the receiving paper body 8 during feeding, ensures the flatness of the receiving paper body 8, reduces the possibility of wrinkles, and also improves the accuracy during slitting.

[0027] Specifically, the leveling mechanism includes a second guide assembly 11 and a leveling assembly 12. The structure of the second guide assembly 11 is the same as that of the first guide assembly 9. The position height of the second guide assembly 11 is the same as that of the first guide assembly 9 and the fourth guide assembly 14. The leveling assembly 12 is located directly above the second guide assembly 11. The leveling assembly 12 includes a top frame 1201, an electric push rod 1202, a lifting plate 1203, and an elastic airbag 1204. The bottom ends of both ends of the top frame 1201 are connected to the frame 1. The electric push rods 1202 are symmetrically arranged on the upper end of the top frame 1201. The output end of the electric push rod 1202 is connected to the lifting plate 1203. Furthermore, an elastic airbag 1204 is provided at the lower end of the lifting plate 1203. The elastic airbag 1204 is connected to a suction pump 1206 located in the middle of the upper end of the lifting plate 1203 via a connecting pipe 1205. The lifting plate 1203 is pushed down by an electric push rod 1202 to adjust the distance between the bottom of the elastic airbag 1204 and the surface of the receiving paper body 8. Then, the suction pump 1206 is started to deliver external air into the elastic airbag 1204 through the connecting pipe 1205, so that the bottom end of the elastic airbag 1204 contacts and adheres to the surface of the receiving paper body 8. Under the action of gravity, the wrinkles of the receiving paper body 8 are smoothed out, improving the accuracy and quality of subsequent slitting.

[0028] In use, the lower surface of the splice paper body 8 is attached to the upper middle surface of the first guide component 9, and then the upper surface of the splice paper body 8 is attached to the lower middle surface of the tension component 10. It then passes between the second guide component 11 and the leveling component 12. The leveling component 12 is then adjusted so that the two sides of the splice paper body 8 are attached to the upper middle surface of the second guide component 11 and the lower bottom of the elastic airbag 1204, respectively. Then, under the cutting of the slitting blade 15, the splice paper body 8 is cut into splice paper bodies 8 of the same size. The waste strips generated after cutting are conveyed under the action of the third guide component 13, and the cut splice paper bodies 8 are guided and conveyed by the fourth guide component 14.
