The first driving roller and the second driving roller are used to drive the spliced paper to be conveyed downward."

[0004] Regarding the above description, the applicant believes that the following problems exist:

[0005] During the use of this utility model, since a paper breaking block is movably arranged in the activity groove, a paper receiving board is arranged on one side of the limiting roller, a second electric telescopic rod for driving the paper receiving board to linearly move towards the limiting roller is installed on one side of the roller conveyor, the linear movement of the paper receiving board is used to drive the paper breaking block to move upward for paper breaking, a first driving roller and a second driving roller are arranged below the limiting roller, and the first driving roller and the second driving roller are used to drive the spliced paper to be conveyed downward. This device uses more components but has insufficient paper roll alignment accuracy and fails to use the mechanism itself for linkage cutting of the paper roll. Therefore, it is necessary to improve a rapid paper splicing and roll changing mechanism to solve the above problems. Summary of the Utility Model

[0006] In order to overcome the problems of the existing rapid paper splicing and roll changing mechanism, which has more components but insufficient paper roll alignment accuracy and fails to use the mechanism itself for linkage cutting of the paper roll.

[0007] The technical solution of the present utility model is as follows: A fast paper feeding and roll changing mechanism, including a track support. Above the track support, there are at least two load-bearing moving modules which can carry a paper roll cylinder. The paper roll cylinder includes wound paper. Below the track support, a sliding positioning device is hung. The track support can tow the paper to above the paper receiving device. The paper receiving device includes a paper receiving main body, and there are two clamping plates on the paper receiving main body. The clamping plates can fix the roller group in the width direction of the track support. The roller group includes a small roller and a large roller. The diameter of the large roller is larger than that of the small roller, and the small roller is located on the left side of the large roller.

[0008] Preferably, the load-bearing moving module moves the paper roll cylinder above the paper receiving device, so that the paper receiving device processes the paper receiving of the paper on the paper roll cylinder. Among them, the diameter of the large roller is larger than that of the small roller, and the small roller is located on the left side of the large roller, which is convenient for the roller group to pick up the paper for paper receiving for subsequent processing. In order to facilitate the accurate paper receiving of the roller group, the sliding positioning device of the track support can effectively clamp the paper and drag the paper above the roller group.

[0009] As a preference, a tool rest is installed on the right side of the roller group, and a cutting knife is installed on the tool rest. The cutting knife includes a blade edge, and the blade edge is arranged on the upper side of the large roller and to the left of the track support. The paper can be cut off through the blade edge, so as to facilitate the operation of quickly changing the roll and connecting the paper for the next paper roll cylinder.

[0010] As a preference, there are two sets of track edges above the track support. The track edges are located on both sides of the track support. The track edge includes two baffles arranged along the length direction of the track support. The load-bearing moving module includes two load-bearing groups respectively located inside the track edges. The load-bearing group includes load-bearing wheels. The load-bearing wheels are restricted within the baffles formed by the track edges. Above the load-bearing wheels, there is a load-bearing bracket. Above the load-bearing bracket, there is a groove. A round rod inserted axially along the paper roll cylinder can be placed in the groove. The reason why the load-bearing moving module can move is because of the load-bearing wheels. The load-bearing wheels are restricted to move within the baffles to prevent deviation. The groove of the load-bearing moving module is used to carry the paper roll cylinder.

[0011] As a preference, the distance between the bottom of the load-bearing bracket and the baffle is a, and a is less than two millimeters to prevent the load-bearing moving module from clamping fingers or causing other injuries to personnel above the track support. The distance of a needs to be less than two millimeters.

[0012] As a preference, cylindrical blocks are provided at both ends of the round rod, and bearings can be sleeved on the cylindrical blocks. The diameter of the bearing is equal to the diameter of the round rod. In order to ensure the smooth rolling of the paper roll cylinder relative to the load-bearing moving module, the method of sleeving bearings at the cylindrical blocks is adopted.

[0013] Preferably, the sliding positioning device includes a sliding plate, on which a slider is provided. Below the rail bracket, a slide rail corresponding to the slider is provided. Below the sliding plate, a rotary cylinder is provided. The rotary cylinder includes a power output shaft, and the direction of the power output shaft points to the right side of the rail bracket. The roll paper is clamped by the rotary cylinder to prevent the roll paper tube from shaking as it moves with the load-carrying moving module.

[0014] Preferably, the lower part of the sliding plate includes a recessed mounting position, in which a servo motor can be installed. The servo motor includes a rotating shaft, and a roller is sleeved on the rotating shaft. The roller can be in contact with the rail bracket. In order to accurately drag the roll paper into the roller group, the power source of the sliding positioning device comes from the servo motor, which realizes accurate dragging and prevents the failure to align and thus unable to perform rapid paper changing and roll replacement.

[0015] Advantages of the present utility model:

[0016] 1. The load-carrying moving module moves the roll paper tube above the paper receiving device, enabling the paper receiving device to process the roll paper on the roll paper tube. Among them, the diameter of the large roller is larger than that of the small roller, and the small roller is located on the left side of the large roller, which is convenient for the roller group to pick up the roll paper for paper receiving for subsequent processing.

By carrying the moving module 2 to move the paper roll 21 to the top of the paper receiving device 4, the paper receiving device 4 processes the paper roll 211 on the paper roll 21, wherein the diameter of the large roller 4122 is larger than the diameter of the small roller 4121, and the small roller 4121 is located on the left side of the large roller 4122, so that the roller group 412 can pick up the paper roll 211 for paper collection for subsequent processing. In order to facilitate the accurate paper collection of the roller group 412, the sliding positioning device 3 of the track bracket 1 can effectively clamp the paper roll 211 and drag the paper roll 211 to the top of the roller group 412, wherein the diameter of the large roller 4122 is larger than the diameter of the small roller 4121, and the small roller 4121 is located on the left side of the large roller 4122 to facilitate the paper roll 211 to be brought into the roller group 412 by the sliding positioning device 3, and the small roller 4121 plays a role of avoidance.

[0029] Please refer to Figures 1-5 In this embodiment, a tool rest 413 is installed on the right side of the roller set 412. A cutting tool 4131 is installed on the tool rest 413. The cutting tool 4131 includes a cutting edge 4132, and the cutting edge 4132 is arranged above the large roller 4122 and to the left of the track bracket 1. The cutting edge 4132 can cut off the rolled paper 211, so as to facilitate the operation of quickly changing the roll and connecting the paper for the next roll paper tube 21. Above the track bracket 1, there are two sets of track edges 11. The track edges 11 are located on both sides of the track bracket 1. The track edge 11 includes two baffles 111 arranged along the length direction of the track bracket 1. The load-carrying moving module 2 includes two load-carrying groups 22 respectively located within the track edges 11. The load-carrying group 22 includes load-carrying wheels 221. The load-carrying wheels 221 are restricted within the baffles 111 formed by the track edges 11. Above the load-carrying wheels 221, there is a load-carrying bracket 222. Above the load-carrying bracket 222, there is a groove 2221. A round rod 23 inserted axially along the roll paper tube 21 can be placed within the groove 2221. The reason why the load-carrying moving module 2 can move is because of the load-carrying wheels 221. The load-carrying wheels 221 are restricted to move within the baffles 111 to prevent deviation. The load-carrying moving module 2 carries the roll paper tube 21 by means of the groove 2221. The distance between the bottom of the load-carrying bracket 222 and the baffle 111 is a, and a is less than two millimeters. To prevent the load-carrying moving module 2 from clamping fingers or causing other injuries above the track bracket 1, the distance a needs to be less than two millimeters. Both ends of the round rod 23 are provided with cylindrical blocks 231. The cylindrical blocks 231 can be sleeved with bearings 232. The diameter of the bearing 232 is equal to the diameter of the round rod 23. In order to enable the roll paper tube 21 to roll smoothly relative to the load-carrying moving module 2, the method of sleeving the bearings 232 at the cylindrical blocks 231 is adopted.

[0030] Please refer to Figures 6-7 In this embodiment, the sliding positioning device 3 includes a sliding plate 31. A slider 311 is arranged on the sliding plate 31. A slide rail 12 corresponding to the slider 311 is arranged below the track bracket 1. A rotary cylinder 312 is arranged below the sliding plate 31. The rotary cylinder 312 includes a power output shaft 3121, and the direction of the power output shaft 3121 points to the right side of the track bracket 1. The rolled paper 211 is clamped by the rotary cylinder 312 to prevent the roll paper tube 21 from shaking as the load-carrying moving module 2 moves. The lower part of the sliding plate 31 includes a recessed mounting position 313. A servo motor 314 can be installed within the mounting position 313. The servo motor 314 includes a rotary shaft 315. A roller 316 is sleeved at the rotary shaft 315. The roller 316 can be in contact with the track bracket 1. In order to accurately drag the rolled paper 211 into the roller set 412, the power source of the sliding positioning device 3 comes from the servo motor 314 to achieve accurate dragging and prevent the inability to perform quick paper connection and roll change due to misalignment.

[0031] When working, please refer to Figure 8 as described, where Figure 8 The left figure shows the initial state. The roller group 412 of the paper receiving device 4 receives the roll paper 211 in the carrying and moving module 2 located above the paper receiving device 4 for subsequent processing. When the roll paper cylinder 21 above the paper receiving device 4 is about to be used up, the carrying and moving module 2 located on the left side of the roll paper cylinder 21 will move to the right. At the same time, the sliding positioning device 3 clamps the roll paper 211 of the unused roll paper cylinder 21 through the rotary cylinder 312 and moves to the right together with the carrying and moving module 2. The carrying and moving module 2 where the roll paper cylinder 21 of the unused roll paper 211 pushes away the carrying and moving module 2 where the roll paper cylinder 21 about to be used up and moves forward. Please refer to Figure 8 the right figure. The blade 4132 on the paper receiving device 4 will cut the roll paper 211. At the moment when the blade 4132 cuts the roll paper 211 that is about to be used up, the roll paper 211 of the unused roll paper cylinder 21 is clamped by the sliding positioning device 3 and dragged above the roller group 412. At the moment when the blade 4132 cuts the roll paper 211, the roll paper 211 of the unused roll paper cylinder 21 is connected and continues to be used for the paper receiving device 4 to receive paper. When the sliding positioning device 3 transfers the roll paper 211 in place, the rotary cylinder 312 rotates around the roll paper 211 and moves to the left, returning to the original position. Here, the carrying and moving module 2 is driven by a general motor. The reason why the sliding positioning device 3 can be accurately driven and positioned is that a reference photoelectric sensor is assembled on the track support 1. This mechanism is driven by a programmable controller or a motion control board. Its working principle will not be elaborated here.

[0032] Through the above steps, the roll paper cylinder 21 is moved above the paper receiving device 4 by the carrying and moving module 2, so that the paper receiving device 4 processes the roll paper 211 on the roll paper cylinder 21. Among them, the diameter of the large roller 4122 is larger than that of the small roller 4121. The small roller 4121 is located on the left side of the large roller 4122, which is convenient for the roller group 412 to pick up the roll paper 211 for paper receiving for subsequent processing. In order to facilitate the accurate paper receiving of the roller group 412, the sliding positioning device 3 of the track support 1 can effectively clamp the roll paper 211 and drag the roll paper 211 above the roller group 412 to solve the problems of the existing fast paper splicing and roll changing mechanism, which has many components but insufficient roll paper alignment accuracy and fails to use the mechanism itself for linkage cutting of the roll paper.
