Description

Technical Field

[0001] This utility model relates to the field of wireless binding machine technology, and in particular to a milling mechanism for controlling the depth of slotting in bound books. Background Technology

[0002] The advent of perfect binding machines allows users to easily produce beautiful contracts, meeting manuals, presentations, operating instructions, tenders, insurance policies, and personalized notebooks at their workplace. These machines offer advantages such as small size, rapid preheating, low power consumption, fast binding, high thickness tolerance, and simple operation, replacing traditional plastic binding strips. A typical perfect binding machine includes a milling mechanism, a gluing mechanism, and a cover packaging device. Before perfect binding, the milling mechanism first mills the edges of the paper to be bound, leaving numerous grooves. After milling, the paper edges slide over the gluing mechanism, allowing the glue to adhere to the edges. Finally, the cover clamping and forming device attaches the cover to the bound paper, completing the perfect binding. The depth of the grooves affects the firmness of the bound book. However, existing perfect binding machines cannot freely adjust the milling depth of the edges of the paper to be bound according to actual needs, failing to meet practical requirements. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a milling mechanism for controlling the depth of slotting in perfect bound books.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a milling mechanism for controlling the depth of slotting in perfect bound books, including a platform, a paper clamping assembly on the platform, a paper milling assembly located below the paper clamping assembly, and an adjustment assembly for adjusting the angle between the platform and the horizontal plane to adjust the distance between the paper clamping assembly and the paper milling assembly. The adjustment assembly includes a base, a mounting part connected to the bottom of the platform, a linkage part on one side of the mounting part, a lifting part for adjusting the longitudinal height of the linkage part to drive the mounting part to swing on one side, and a rotating support part on the other side of the mounting part for supporting the rotation of the mounting part.

[0006] Furthermore, the mounting part includes a base and two horizontal plates connecting the base and the bottom of the platform.

[0007] Furthermore, the linkage includes slide rods symmetrically arranged at both ends of one of the horizontal plates, lifting blocks that slide in cooperation with the slide rods, waist holes passing through the lifting blocks for the slide rods to pass through, and reinforcing plates connecting the two lifting blocks.

[0008] Furthermore, the lifting unit includes a positioning seat corresponding to the slide bar and disposed on the base, an adjusting rod passing through the positioning seat, a first thread and a second thread disposed on the adjusting rod, a translation block screwed to the first thread and the second thread respectively, and a push-pull plate whose two ends are rotatably connected to the lifting block and the translation block respectively.

[0009] Furthermore, the adjusting rod is provided with a limiting sleeve.

[0010] Furthermore, the rotating support includes two support plates mounted on the base, a rotating shaft rotatably connected to the support plates, and an intermediate shaft with both ends connected to the rotating shaft. The intermediate shaft is fixedly connected to the mounting part.

[0011] Furthermore, the cross-section of the intermediate shaft is polygonal.

[0012] The milling mechanism for controlling the depth of grooves in perfect-bound books proposed in this utility model has the following advantages:

[0013] This invention adjusts the angle between the platform and the horizontal plane by setting up a linkage part and a lifting part to raise and lower one side of the mounting part, and using a rotating support part to support the other side of the mounting part when it rotates. This allows for adjustment of the distance between the paper clamping assembly and the paper milling assembly, thereby achieving precise control of the paper milling depth.

In this embodiment, the angle adjustment range is 0°-30°. The adjustment assembly 4 includes a base 401, a mounting part 402 connected to the bottom of the platform 1, a linkage part 403 disposed on one side of the mounting part 402, a lifting part 404 disposed on the base 401 for adjusting the longitudinal height of the linkage part 403 to drive the mounting part 402 to swing on one side, and a rotating support part 405 disposed on the other side of the mounting part 402 for supporting the rotation of the mounting part 402.

[0020] This utility model uses a linkage part 403 and a lifting part 404 to lift one side of the mounting part 402, and a rotating support part 405 to support the other side of the mounting part 402 when it rotates, so as to adjust the angle between the platform 1 and the horizontal plane, thereby adjusting the distance between the paper clamping assembly 2 and the paper milling assembly 3, and achieving precise control of the paper milling depth.

[0021] In an optional embodiment of this utility model, the mounting part 402 includes a base 4021 and two horizontal plates 4022 that connect the base 4021 and the bottom of the platform 1. After the base 4021 and the platform 1 are connected by the two horizontal plates 4022, one side of the base 4021 swings under the push of the linkage part 403 and the lifting part 404, and the other side is supported by the rotating support part 405.

[0022] In an optional embodiment of this utility model, the linkage part 403 includes a sliding rod 4031 symmetrically arranged at both ends of one of the horizontal plates 4022, a lifting block 4032 that slides with the sliding rod 4031, a waist hole 4033 passing through the lifting block 4032 for the sliding rod 4031 to pass through, and a reinforcing plate 4034 connecting the two lifting blocks 4032. In this embodiment, the lifting block 4032 is raised and lowered under the drive of the lifting part 404, so that the sliding rod 4031 slides in the waist hole 4033, and at the same time the sliding rod 4031 drives the horizontal plate 4022 to swing at a small angle along the rotating support part 405.

[0023] In an optional embodiment of this utility model, the lifting part 404 includes a positioning seat 4041 corresponding to the slide rod 4031 and disposed on the base 401, an adjusting rod 4042 passing through the positioning seat 4041, a first thread 4043 and a second thread 4044 disposed on the adjusting rod 4042, a translation block 4045 screwed to the first thread 4043 and the second thread 4044 respectively, and a push-pull plate 4046 whose two ends are rotatably connected to the lifting block 4032 and the translation block 4045 respectively. In this embodiment, the positioning seat 4041 is fixed on the base 401, and the bottom of the translation block 4045 is slidably connected to the base 401. The first thread 4043 and the second thread 4044 have opposite thread directions. By rotating the adjusting rod 4042, the two translation blocks 4045 move relative to each other, and the lifting block 4032 is pushed up and down by the push-pull plate 4046, which in turn drives the slide rod 4031 to slide in the waist hole 4033, so that the horizontal plate 4022 swings at a small angle along the rotating support part 405.

[0024] In an optional embodiment of this utility model, a limiting sleeve 4047 is provided on the adjusting rod 4042. By setting the limiting sleeve 4047, the distance between the two translation blocks 4045 is prevented from being too close.

The intermediate shaft 4053 is fixedly connected to the mounting part 402. Preferably, in this embodiment, the intermediate shaft 4053 is connected to the base 4021 by bolts. The base 4021 rotates along the intermediate shaft 4053, and at the same time, the rotating shaft 4052 supports the rotation of the base 4021.

[0026] In an optional embodiment of this invention, the cross-section of the intermediate shaft 4053 is polygonal.
