Description

Technical Field

[0001] The utility model relates to the technical field of mechanical manufacturing, in particular to a multi-size chuck used for a base paper stand of a cardboard line pit machine. Background Art

[0002] In the production process of packaging products such as cartons and paper boxes, base paper racks (also called cardboard racks or cardboard pallets) are indispensable materials. Since different specifications of packaging products have different requirements for the size of base paper racks, a base paper rack clamp that can adapt to various sizes is needed. With the rapid development of the packaging industry, production efficiency has become the key to corporate competition. Traditional fixed-size clamps cannot adapt to diverse production needs, resulting in low production efficiency, increased changeover time and labor costs.

[0003] In actual use, if a cardboard line pit machine base paper frame with multi-size chucks is only suitable for 3-inch base paper frames and cannot adapt to base paper frames of other sizes, it limits the versatility and flexibility of the equipment. Utility Model Content

The second sliding groove design provided on the circumferential surface of the first fixed ring can accurately match the size of a six-inch paper core, ensuring that the paper core will not shift or loosen during the installation process. Since the clamp can stably clamp the six-inch paper core, the downtime caused by paper core displacement or loose clamping is reduced, thereby improving production efficiency.

[0005] To achieve the above-mentioned purpose, a multi-size chuck for a base paper stand of a cardboard line pit machine is provided, comprising: a first fixed ring, a second sliding groove is provided on the circumferential surface of the first fixed ring, a second positioning column is fixedly connected to the inner rear side of the second sliding groove, a second spring is sleeved on the cylindrical surface of the second positioning column, a second interference block is slidably connected to the inner side of the second sliding groove, and the rear side of the second interference block contacts the second spring, a second interference groove is provided on the rear side of the second interference block, and the interior of the second interference groove is slidably connected to the circumferential surface of the second positioning column, a positioning hole is provided on the circumferential surface of the first fixed ring, an arc slider is fixedly connected to the inner ring of the first fixed ring, a fixed column is slidably connected to the inner ring of the first fixed ring, an arc groove is provided on the circumferential surface of the fixed column, and the arc groove and the arc slider are slidably connected. This design achieves precise control of cardboard size through the precise coordination of the sliding groove and the positioning column, improving the stability and efficiency of installation.

[0006] According to the multi-size clamp for a paperboard line pit machine base paper holder, a second fixing ring is fixedly connected to the front side of the first fixing ring, and a first sliding groove is defined on the circumferential surface of the second fixing ring.

[0007] According to the multi-size chuck for a paperboard line pit machine base paper holder, a first abutment block is slidably connected within the first sliding groove, and a first abutment groove is defined at the bottom end of the first abutment block. This design ensures precise alignment of the paperboard holder through the fixed connection of the first positioning post, improving installation accuracy.

[0008] According to the multi-size chuck for the base paper stand of the cardboard line pit machine, the first interference groove is internally slidably connected to a first positioning column, and the bottom end of the first positioning column is fixedly connected to the inner bottom end of the first sliding groove.

[0009] According to the multi-size chuck for a base paper holder for a cardboard line pit machine, a first spring is sleeved on the circumferential surface of the first positioning post, and the top end of the first spring contacts the bottom end of the first abutment block. The left end of the first fixing ring is fixedly connected to a first limiting post, the left end of the fixing post is fixedly connected to a second limiting post, and the left end of the second limiting post is fixedly connected to a mating joint. This design, through the coordination of the spring and limiting post, enables dynamic adjustment and fixation of the cardboard holder, improving the flexibility and stability of the clamp.

[0010] According to the multi-size clamp for a paperboard line pit machine base paper frame, the first and second abutment grooves have T-shaped cross-sections, and the first and second abutment blocks also have T-shaped cross-sections. This design enhances the strength and rigidity of the clamp through the T-shaped cross-section, thereby increasing the service life of the clamp.

[0011] According to the multi-size clamp for a paperboard line pit machine base paper frame, the number of the first sliding slots and the second sliding slots are both eight, and the interiors of the first sliding slots and the second sliding slots are identically configured. This design, through the provision of multiple sliding slots, expands the applicability of the clamp and improves the versatility of the equipment.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model is provided with a second sliding groove, a second positioning column, a second spring, a second contact block, a positioning hole, an arc slider, a fixing column and an arc groove, and the second sliding groove design opened on the circumferential surface of the first fixing ring can accurately match the size of the six-inch paper core, ensuring that the paper core will not shift or loosen during the installation process. Since the clamp can stably clamp the six-inch paper core, the downtime caused by the displacement of the paper core or the loose clamping is reduced, thereby improving production efficiency.
