Description

Technical Field

[0001] This utility model relates to the field of automatic paper splicing machine technology, and specifically to an automatic paper splicing machine. Background Technology

[0002] In paper processing, to avoid production line downtime, an automatic paper splicer is used to connect new and old paper rolls together, providing a continuous paper supply to the production line and enabling production to continue without stopping.

[0003] Chinese patent document CN211141074U discloses an automatic paper splicer that operates without stopping the machine. The machine moves within a slot No. 3 via a rotating shaft until the paper from the No. 2 paper roll comes into contact with the paper from the No. 1 paper roll. With the help of adhesive, the first end of the No. 2 paper roll is bonded to the last end of the No. 1 paper roll, thus achieving automatic paper splicing without stopping the machine.

[0004] However, in the above scheme, the No. 3 rotating shaft is located above the No. 2 paper roll, and the paper conveying direction is located above the No. 1 paper roll. This causes the new paper roll placed on the No. 1 paper roll to be unable to connect with the No. 3 rotating shaft, resulting in the inability of the paper rolls to be continuously connected, which affects production efficiency. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an automatic paper splicing machine.

[0006] The technical solution of this utility model is: an automatic paper splicer, comprising a mounting frame, a motor, a support roller, a mounting block, a conveying roller, and an adjustment assembly;

[0007] There are two mounting blocks, which are symmetrically installed in the middle of the inner side of the mounting frame and extend outward from the end of the mounting frame; the motor is installed on the outside of the mounting frame and is connected to the end of the mounting blocks for transmission.

[0008] The number of conveyor rollers is four, and all four conveyor rollers are rotatably mounted in the middle of the mounting block;

[0009] The number of adjustment components is four, and the four adjustment components are respectively set at the ends of the two mounting blocks and connected to the conveyor roller bearing;

[0010] The support rollers are installed at the top of the mounting frame.

[0011] Preferably, a stop is provided at the top of the mounting block and between the two conveying rollers, and the bottom side of the stop is provided with an inclined surface.

[0012] Preferably, the inclined surface is arc-shaped and has a gap between the inclined surface and the outer side of the conveyor roller.

[0013] Preferably, the outer diameter of the conveyor roller is larger than the width of the mounting block.

[0014] Preferably, the adjusting assembly includes bolts and connecting blocks;

[0015] The connecting block is installed on the inner side of one end of the mounting block and connected to the conveyor roller bearing;

[0016] The bolt is rotatably installed at one end of the mounting block and inserted into the inside of the connecting block.

[0017] Preferably, one end of the mounting block is provided with a mounting hole, which is waist-shaped, and the connecting block is accommodated in the mounting hole when the connecting block and the mounting block are installed together.

[0018] Preferably, one end of the connecting block is provided with a threaded hole, and one end of the bolt passes through the mounting block and is inserted into the threaded hole, and the size of the bolt is arranged to match the threaded hole.

[0019] Preferably, a connecting ring is provided at the other end of the bolt, and a limiting plate is provided at one end of the mounting block. The limiting plate is sleeved on the other end of the bolt and wrapped around the outside of the connecting ring.

[0020] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0021] This invention involves symmetrically installing two mounting blocks. When one mounting block is working, the conveying roller in the other mounting block clamps the end of the new paper roll. At the same time, with the help of a motor, the end of the new paper roll is moved towards the old paper roll and tightly adhered to it. The above operation steps are repeated to ensure uninterrupted continuous connection between the new and old paper rolls, thereby improving production efficiency. Attached Figure Description

[0028] Example 1

[0029] like Figure 1-5 As shown, the present invention proposes an automatic paper splicing machine, which includes a mounting frame 1, a motor 2, a support roller 3, a mounting block 4, a conveying roller 5, and an adjustment component 7;

[0030] There are two mounting blocks 4, which are symmetrically installed in the middle of the inner side of the mounting frame 1 and extend to the outer side of the mounting frame 1 at their ends; the motor 2 is installed on the outer side of the mounting frame 1 and is connected to the end of the mounting block 4 for transmission. The motor 2 and the mounting block 4 are arranged in a one-to-one correspondence.

[0031] There are four conveyor rollers 5, and all four conveyor rollers 5 are rotatably mounted in the middle of the mounting block 4. The outer diameter of the conveyor roller 5 is larger than the width of the mounting block 4, so as to prevent the two mounting blocks 4 from contacting each other first when the two conveyor rollers 5 move relative to each other, which would prevent the conveyor rollers 5 from connecting the ends of the two paper rolls.

[0032] The number of adjustment components 7 is four. The four adjustment components 7 are respectively set at the ends of the two mounting blocks 4 and connected to the bearings of the conveying roller 5. They are used to adjust the position of the conveying roller 5 on the mounting block 4 during use, so as to adjust the spacing between the two conveying rollers 5 on the mounting block 4, and to clamp and convey paper of different thicknesses between the two conveying rollers 5.

[0033] The support roller 3 is installed at the top of the mounting frame 1. The number of support rollers 3 is one or two. When there is one support roller 3, the support roller 3 supports the paper at the paper roll conveying point. When there are two support rollers 3, the two support rollers 3 can clamp and convey the paper.

[0034] In this embodiment, a motor 2 drives a mounting block 4 to rotate vertically within the mounting frame 1, conveying the end of the paper roll between two conveying rollers 5. Simultaneously, the paper roll moves towards the support roller 3 for processing. Before the paper roll is used up, the end of a new paper roll is placed between the two conveying rollers 5 of the two mounting blocks 4, and the paper end is bent away from the mounting block 4 and placed against the conveying roller 5. Adhesive such as glue is applied to the reverse side. At the same time, the motor 2 drives another mounting block 4 to rotate towards the first mounting block 4, causing the other mounting block 4 to move the conveying roller 5 with the paper end placed against it towards the conveying roller 5 of the first mounting block 4. This brings the end of the new paper roll into contact with the old paper roll, and the two mounting blocks 4 are clamped and conveyed by the conveying rollers 5, ensuring a tight fit between the end of the new paper roll and the old paper roll. The first mounting block 4 is then reset, and the above operation steps are repeated until the new paper roll completely replaces the old paper roll, achieving continuous and stable paper supply, improving production efficiency, and reducing manual intervention costs.

[0035] Example 2

[0036] like Figure 1-2 and Figure 4 As shown, the present invention proposes an automatic paper splicing machine. Compared with the first embodiment, the difference in this embodiment is that a stop block 6 is provided at the top of the mounting block 4 and between the two conveying rollers 5. An inclined surface 9 is provided on the bottom side of the stop block 6. The inclined surface 9 is arc-shaped and has a gap with the outer side of the conveying roller 5.

[0037] In this embodiment, by setting a stop block 6 at the top of the mounting block 4 and setting an inclined surface 9 on the side of the stop block 6, and making the stop block 6 arc-shaped, when the end of the paper roll moves from the bottom to the top between the two conveying rollers 5, the arc-shaped inclined surface 9 guides the paper to bend towards the top of the conveying roller 5 and place it in the connection area between the conveying roller 5 and the mounting block 4 in the tooling state, ensuring accurate docking of the end of the paper roll.

[0038] Example 3

[0039] like Figure 3 As shown, the automatic paper splicing machine proposed in this utility model differs from the first embodiment in that the adjusting component 7 includes a bolt 71 and a connecting block 72.

[0040] The connecting block 72 is installed on the inner side of one end of the mounting block 4 and connected to the bearing of the conveyor roller 5;

[0041] Bolt 71 is rotatably installed at one end of mounting block 4 and inserted into the inside of connecting block 72.

[0042] In an optional embodiment, one end of the mounting block 4 is provided with a mounting hole 8, which is waist-shaped. When the connecting block 72 and the mounting block 4 are installed together, the connecting block 72 is accommodated in the mounting hole 8.

[0043] In an optional embodiment, one end of the connecting block 72 is provided with a threaded hole 73, and one end of the bolt 71 passes through the mounting block 4 and is inserted into the threaded hole 73, and the size of the bolt 71 is arranged to match the threaded hole 73.

[0044] In this embodiment, the conveying roller 5 is connected to the mounting block 4 and the connecting block 72 respectively through bearings, and the connecting block 72 is moved inside the mounting hole 8 when the bolt 71 is rotated through the engagement of the bolt 71 and the threaded hole 73. This causes the connecting block 72 to drive the conveying roller 5 to move synchronously, thereby adjusting the distance between the two conveying rollers 5 so that paper of different thicknesses can be placed between the two conveying rollers 5.

[0045] Example 4

[0046] like Figure 3 As shown, the present invention proposes an automatic paper splicing machine. Compared with embodiment three, the difference in this embodiment is that a connecting ring 74 is provided at the other end of the bolt 71, and a limiting plate 10 is provided at one end of the mounting block 4. The limiting plate 10 is sleeved on the other end of the bolt 71 and wrapped around the outside of the connecting ring 74.

[0047] In this embodiment, by setting a connecting ring 74 at the other end of the bolt 71 and having the limiting plate 10 at the end of the mounting block 4 wrap around the outside of the connecting ring 74, the limiting plate 10 limits the position of the bolt 71, preventing the bolt 71 from moving freely at the end of the mounting block 4, which would cause the position of the conveying roller 5 to be unstable and affect the connection of the paper roll.

[0048] In this invention, a motor 2 drives a mounting block 4 to rotate vertically within the mounting frame 1, conveying the end of the paper roll between two conveying rollers 5. Simultaneously, the paper roll moves towards the support roller 3 for processing. Before the paper roll is used up, the end of a new paper roll is placed between the two conveying rollers 5 of the two mounting blocks 4, and the paper end is bent away from the mounting block 4 and placed against the conveying roller 5. Adhesive such as glue is applied to the reverse side. At the same time, the motor 2 drives another mounting block 4 to rotate towards the first mounting block 4, causing the other mounting block 4 to move the conveying roller 5 with the paper end placed against it towards the conveying roller 5 of the first mounting block 4. This brings the end of the new paper roll into contact with the old paper roll, and the two mounting blocks 4 are clamped and conveyed by the conveying rollers 5, ensuring a tight fit between the end of the new paper roll and the old paper roll. The first mounting block 4 is then reset, and the above operation steps are repeated until the new paper roll completely replaces the old paper roll, achieving continuous and stable paper supply and improving production efficiency.

[0049] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
