Description
Technical Field
[0001] The present application relates to the technical field of roll paper splicing devices, and in particular to a roll paper splicing device. Background Art
[0002] Patterns are printed on the outer surface of the wrapping paper. It is necessary to inspect a long string of wrapping paper. If there are defects on the wrapping paper, the defective part of the wrapping paper needs to be cut. The existing method is that workers hold the wrapping paper, compare the position where the wrapping paper needs to be cut with a steel ruler, and then hold a utility knife to cut the wrapping paper along the edge of the steel ruler. This action is repeated twice to cut off the defective part of the wrapping paper. Finally, the two ends of the separated wrapping paper are glued together with tape to facilitate the wrapping paper to be wound into a cylindrical shape.
[0003] However, with the existing method, the cutting efficiency of the wrapping paper is slow and needs to be improved. Utility Model Content
[0004] The purpose of the present application is to provide a roll paper splicing device to improve the overall cutting efficiency of the wrapping paper.
[0005] A roll paper splicing device provided by the present application adopts the following technical solution: It includes a cutting table, the cutting table is provided with a channel for the wrapping paper to pass through, the cutting table is connected with a bracket, the bracket is slidably connected with a carrier plate, the bracket is connected with a linkage component for driving the carrier plate to slide in a direction close to or away from the channel, and a fixing member and a cutter are arranged on one side of the carrier plate close to the channel.
[0006] By adopting the above technical solution, the wrapping paper moves along the channel. The movement of the wrapping paper and the channel cooperate to play a role in guiding and limiting the movement of the wrapping paper, thereby improving the stability of the movement of the wrapping paper and enabling the wrapping paper to move precisely to the corresponding position. When there are defects on the wrapping paper, the wrapping paper is moved to the corresponding position of the cutter. The linkage component drives the carrier plate to move towards the wrapping paper. The fixing member first abuts against the wrapping paper to improve the stability of the wrapping paper, and then the cutter cuts the wrapping paper. Repeat the above steps to cut the wrapping paper again and remove the defective wrapping paper. The step of comparing the steel ruler with the wrapping paper is omitted, which improves the cutting efficiency of the wrapping paper, and then the two good packaging bags are glued together with tape.
[0007] Optionally, the cutting table is provided with a knife groove for the cutter to be inserted into, and the knife groove communicates with the channel.
[0008] By adopting the above technical solution, the cutter is inserted into the knife groove during the cutting process to prevent the cutter from abutting against the cutting table during the movement, which plays a role in protecting the cutter.
[0009] Optionally, the shortest distance between the side of the cutter away from the carrier plate and the carrier plate decreases step by step along the length direction of the cutter.
[0010] By adopting the above technical solution, the cutting force distribution of the cutter is more uniform, the contact area between the cutter and the wrapping paper is reduced, thereby reducing the friction during cutting and improving the cutting efficiency.
[0011] Optionally, the fixing member is an elastic block connected to the carrier plate, and the end of the cutter away from the carrier plate is located between the carrier plate and the end of the elastic block away from the carrier plate.
[0012] By adopting the above technical solution, when the carrier plate moves towards the wrapping paper, the elastic block first abuts against the wrapping paper and undergoes elastic deformation. The elastic block maintains a tendency of elastic reset, so that the wrapping paper is clamped by the elastic block and the cutting table, improving the stability of the wrapping paper placed on the cutting table. Then the carrier plate continues to move towards the wrapping paper, and the cutter completes the cutting of the wrapping paper.
[0013] Optionally, there are two elastic blocks connected to the carrier plate, and the cutter is located between the two elastic blocks.
[0014] By adopting the above technical solution, the two elastic blocks press both ends of the wrapping paper, improving the stability of the wrapping paper being pressed, that is, improving the cutting effect of the wrapping paper by the cutter.
[0015] Optionally, the linkage assembly includes a rotating rod rotatably connected to the bracket, a gear connected to the rotating rod, and a rack slidably connected to the bracket. The bracket is provided with a chute for slidably cooperating with the rack. The gear meshes with the rack. The rotating rod is provided with a driving rod, and the carrier plate is connected to the rack.
[0016] By adopting the above technical solution, the driving rod drives the rotating rod to rotate, that is, the gear rotates around the axis of the rotating rod. During the rotation of the gear, the gear drives the rack to move towards or away from the cutting table, that is, the cutter and the elastic block move towards or away from the cutting table, thereby completing the cutting of the wrapping paper. The sliding fit between the rack and the chute plays a role in guiding and limiting the sliding of the rack, thereby improving the stability of the sliding of the cutter and the elastic block.
[0017] Optionally, the rack is connected with a connecting plate, and the connecting plate is connected to the bracket through an elastic member.
[0018] By adopting the above technical solution, when the carrier plate moves towards the wrapping paper, the elastic member is compressed to generate elastic deformation and maintains a tendency of elastic reset. After the wrapping paper is cut, the driving rod is released, and the elastic member elastically resets. The elastic member forces the driving rod and the carrier plate to reset for the next operation, improving the working efficiency.
[0019] Optionally, the connecting plate is threadedly connected with a threaded rod. One end of the threaded rod is connected with a bearing, the bearing is connected with a connecting block, one end of the elastic member is connected with the connecting block, and the other end is connected with the bracket.
[0020] By adopting the above technical solution, when the elastic member ages and its tightness needs to be adjusted, rotate the threaded rod to move the connecting block towards or away from the bracket, thereby adjusting the distance between the connecting block and the bracket.
[0021] Optionally, the cutting table is provided with a discharge groove communicating with the channel, and the discharge groove corresponds to the carrier plate.
[0022] By adopting the above technical solution, the cut packaging paper can be moved out of the channel through the discharge groove, improving the efficiency of the packaging paper moving out of the channel.
[0023] Optionally, one side of the cutting table is connected with a mounting post, the mounting post is sleeved with a tape, and the cutting table is connected with a breaking tooth corresponding to the mounting post.
[0024] By adopting the above technical solution, rotate the tape to make the tape rotate around the axis of the mounting post. When the tape moves a certain length, the tape abuts against the breaking tooth, thereby completing the breaking of the tape and facilitating the tearing of the tape.
[0025] In summary, the present application includes at least one of the following beneficial technical effects:
[0026] 1. When there are defects in the packaging paper, move the packaging paper to the corresponding position of the cutting knife. The linkage component drives the carrier plate to move towards the packaging paper. The fixing member first abuts against the packaging paper, thereby improving the stability of the packaging paper, and then the cutting knife cuts the packaging paper. Repeat the above steps to cut the packaging paper again and remove the defective packaging paper. The step of comparing the steel ruler with the packaging paper is omitted, improving the efficiency of the packaging paper being cut, and then sticking two good packaging bags together with tape.
[0027] 2. The cut packaging paper can be moved out of the channel through the discharge groove, improving the efficiency of the packaging paper moving out of the channel. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following will further describe the present application in detail with reference to the Figure 1 - Figure 6 accompanying drawings.
[0036] The embodiment of the present application discloses a roll paper paper splicer.
[0037] Combined with Figure 1 and Figure 2 as shown, it includes a cutting table 1. A channel 11 for the packaging paper to pass through is recessed on the upper surface of the cutting table 1. A discharge chute 12 communicating with the channel 11 is opened on one side of the cutting table 1, and the cut packaging paper can move out of the channel 11 from the discharge chute 12. A mounting post 13 is rotatably connected to the side of the cutting table 1 where the discharge chute 12 is opened. A tape 131 is sleeved on the mounting post 13. A breaking tooth 14, a first baffle 15, a second baffle 16 and a rotating column 17 are fixedly connected to the side of the cutting table 1 where the discharge chute 12 is opened. The first baffle 15 is located between the breaking tooth 14 and the discharge chute 12. The breaking tooth 14 is located between the first baffle 15 and the mounting post 13. The mounting post 13 is located between the breaking tooth 14 and the rotating column 17. The rotating column 17 is located between the mounting post 13 and the second baffle 16. A cover plate 171 is rotatably connected to the rotating column 17. When the tape 131 is not in use, the cover plate 171 covers the breaking tooth 14 to prevent the situation that the staff is accidentally injured by touching the breaking tooth 14.
[0038] Combined with Figure 3 , Figure 4 , Figure 5 and Figure 6As shown in the figure, a support 2 is fixedly connected to the upper surface of the cutting table 1. A carrier plate 3 is slidably connected to one side of the support 2 close to the cutting table 1, and the carrier plate 3 corresponds to the discharge chute 12. The support 2 is connected with a linkage assembly 4 for driving the carrier plate 3 to slide in a direction close to or away from the channel 11. A cutting knife 31 and two fixing members 32 are fixedly connected to one side of the carrier plate 3 close to the channel 11. The fixing member 32 is an elastic block 321 fixedly connected to the carrier plate 3, and the cutting knife 31 is located between the two elastic blocks 321. When the elastic block 321 is not pressed, the end of the cutting knife 31 away from the carrier plate 3 is located between the carrier plate 3 and the end of the elastic block 321 away from the carrier plate 3. The closest distance between the side of the cutting knife 31 away from the carrier plate 3 and the carrier plate 3 gradually decreases along the length direction of the cutting knife 31. A knife groove 18 for the cutting knife 31 to be inserted into is formed in the cutting table 1, and the knife groove 18 communicates with the channel 11.
[0039] The linkage assembly 4 includes a rotating rod 41 rotatably connected to the support 2, a gear 42 fixedly connected to the rotating rod 41, and a rack 43 slidably connected to the support 2. The gear 42 meshes with the rack 43, and a sliding groove 21 for slidably cooperating with the rack 43 is formed in the support 2. A driving rod 44 is provided on the rotating rod 41, and the rotating rod 41 and the driving rod 44 are integrally formed. The carrier plate 3 is fixedly connected to the rack 43. A connecting plate 5 is fixedly connected to the end of the rack 43 away from the carrier plate 3. A threaded rod 51 is threadedly connected to the connecting plate 5. A bearing is fixedly connected to the end of the threaded rod 51 close to the support 2, and a connecting block 52 is fixedly connected to the bearing. The connecting block 52 is connected to the support 2 through an elastic member 53. The elastic member 53 is a spring, and the two ends of the elastic member 53 are respectively fixedly connected to the opposite sides of the connecting block 52 and the support 2.
[0040] The implementation principle of a roll paper paper connecting device in an embodiment of the present application is as follows:
[0041] When there are defects in the wrapping paper, move the wrapping paper along the channel 11 to the corresponding position. Press down the active rod 44, and the active rod 44 drives the rotating rod 41 to rotate around its own axis, that is, the gear 42 rotates around its own axis. The gear 42 drives the rack 43 to slide in the direction close to the wrapping paper, that is, the carrier plate 3, the elastic block 321 and the cutter 31 all slide in the direction close to the wrapping paper. The elastic member 53 is compressed to generate elastic deformation and maintains the tendency of elastic deformation. Until the elastic block 321 first abuts against the wrapping paper and undergoes elastic deformation, so that the wrapping paper is clamped by the elastic block 321 and the cutting table 1, and then the cutter 31 cuts the wrapping paper. Release the active rod 44, and the elastic member 53 returns elastically. The elastic member 53 forces the carrier plate 3, the cutter 31, the elastic block 321 and the active rod 44 to return to their original positions for the next operation. Repeat the above actions to cut the wrapping paper again, and the defective wrapping paper is removed from the discharge chute 12 out of the channel 11. Rotate the tape 131 so that the tape 131 rotates around the axis of the mounting post 13. When the tape 131 moves a certain length, the tape 131 abuts against the breaking teeth 14, thereby completing the breaking of the tape 131, and then sticking two good packaging bags together with the tape 131 for convenient winding.
[0042] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
