[0005] The technical solution of this utility model is implemented as follows: a paper splicer bracket, the paper splicer including a frame and two opposing bases connected to the lower end of the frame, a bracket provided between the two bases, the bracket being provided in two sets, each set of brackets including:

[0006] The main shaft is rotatably connected between the two bases;

[0007] Two slide rails are arranged circumferentially on the radial outer side of the main rotating shaft along the length of the main rotating shaft;

[0008] Two support arms are slidably mounted on the main shaft via slide rails;

[0009] The lead screw, the middle part of which is fixedly mounted on the main shaft via a support shaft seat;

[0010] The lead screw has two support arms running through its two ends. A drive assembly is provided between the support arms and the lead screw to drive the support arms to move axially on the main shaft.

[0011] Furthermore, the support arm has a through hole for the lead screw to pass through, and the drive assembly includes:

[0012] The sleeve is rotatably connected inside the through hole and sleeved on the outside of the lead screw;

[0013] Two retaining rings are fitted and fixed at the two openings of the through hole at both ends of the sleeve;

[0014] The sleeve has an internal thread on its radial inner side that mates with the lead screw.

[0015] Furthermore, the driver components also include:

[0016] The drive motor is fixedly mounted on the support arm;

[0017] The drive gear is connected and fixed to the output shaft of the drive motor.

[0018] One of the retaining rings on the sleeve is fitted with a driven gear that meshes with the drive gear.

[0019] Furthermore, one end of the main shaft passes through the base and is fitted with a driven gear two. A hydraulic cylinder is fixedly installed on the outer side of the base, and a rack that meshes with the driven gear two is fixedly installed on the output end of the hydraulic cylinder.

[0020] Furthermore, the two sets of brackets are arranged in a mirror image.

[0021] Furthermore, the outer radial side of the sleeve abuts against the inner radial side of the through hole.

[0030] Example 1:

[0031] like Figure 1 As shown in the figure, this utility model discloses a paper splicer bracket. The paper splicer includes a frame 1 and two opposing bases 2 connected to the lower end of the frame 1. A bracket is provided between the two bases 2. The bracket is characterized in that it is provided in two sets, and each set of brackets includes:

[0032] The main shaft 3 is rotatably connected between the two bases 2;

[0033] Two slide rails 4 are arranged circumferentially on the radial outer side of the main rotating shaft 3 along the length of the main rotating shaft 3;

[0034] Two support arms 5 are slidably mounted on the main rotating shaft 3 via slide rails 4;

[0035] The lead screw 6 is fixedly mounted on the main rotating shaft 3 via a support shaft seat;

[0036] The two ends of the lead screw 6 are respectively connected to two support arms 5. A drive assembly is provided between the support arms 5 and the lead screw 6 to drive the support arms 5 to make axial displacement on the main rotating shaft 3.

[0037] In the above technical solution, the slide rail is connected and fixed to the main rotating shaft by internal hex bolts;

[0038] By adopting the above technical solution, and through the coordinated arrangement of the lead screw, drive components and slide rails, the two support arms can flexibly adjust the spacing according to different specifications of paper rolls, thereby ensuring that each specification of paper roll can be stably supported in the appropriate position, ensuring smooth and stable operation, and improving the overall functionality and reliability of the equipment.

[0039] Example 2:

[0040] This embodiment provides a paper splicer bracket, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0041] Furthermore, the support arm 5 has a through hole for the lead screw 6 to pass through, and the drive assembly includes:

[0042] Sleeve 7 is rotatably connected inside the through hole and sleeved on the outside of lead screw 6;

[0043] Two retaining rings 8 extend from the two openings of the through hole at both ends of the sleeve 7 and are fixed in place.

[0044] The sleeve 7 has an internal thread on its radial inner side that mates with the lead screw 6.

[0045] By adopting the above technical solution, the lead screw is fixed by the support shaft seat and is in a static state. The sleeve is limited in the through hole by the retaining ring and will not move axially in the through hole. When the sleeve rotates in the forward or reverse direction, since the sleeve and the lead screw are connected by a thread, the support arm is limited by the slide rail and can only move in the axial direction of the main shaft. The rotating sleeve can drive the support arm that it is in contact with to move back in the axial direction of the main shaft, so as to achieve the purpose of adjusting the distance between the two support arms.

[0046] Example 3:

[0047] This embodiment provides a paper splicer bracket, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0048] Furthermore, the driver components also include:

[0049] The drive motor 9 is fixedly mounted on the support arm 5;

[0050] The drive gear is fixedly connected to the output shaft of the drive motor 9;

[0051] One of the retaining rings 8 of the sleeve 7 is fitted with a driven gear 10 that meshes with the drive gear.

[0052] By adopting the above technical solution, each support arm is equipped with a separate drive motor to control the rotation of the sleeve, so that the two support arms can move independently without interfering with each other.

[0053] Example 4:

[0054] This embodiment provides a paper splicer bracket, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0055] Furthermore, one end of the main shaft 3 passes through the base 2 and is fitted with a driven gear 11. A hydraulic cylinder is fixedly installed on the outer side of the base 2, and a rack that meshes with the driven gear 11 is fixedly installed on the output end of the hydraulic cylinder.

[0056] By adopting the above technical solution, the main shaft can be rotated by the hydraulic cylinder pushing the rack, so as to lift the support arm and adapt to rolls of paper of different diameters.

[0057] Example 5:

[0058] This embodiment provides a paper splicer bracket, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0059] Furthermore, the two sets of brackets are arranged in a mirror image.

[0060] By adopting the above technical solution, the two brackets do not interfere with each other.

[0061] Example 6:

[0062] This embodiment provides a paper splicer bracket, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0063] Furthermore, the radially outer side of the sleeve 7 abuts against the radially inner side of the through hole.

[0064] By adopting the above technical solution, the support arm can be stably matched with the sleeve, and it is not easy for it to move.

[0065] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
