Description

Technical Field

[0001] This utility model relates to the technical field of pith processing equipment, specifically to a pith core extracting machine mold head. Background Technology

[0002] Traditional core extraction from pith paper relies on manual operation, using a single pusher to extract the pith from each stem individually. This method suffers from low efficiency, easy damage to the pith, and inability to adapt to different stem diameters. Existing mechanical core extraction equipment mostly uses pushers of fixed diameter, requiring frequent component replacements to accommodate different sizes of pith paper, resulting in cumbersome operation and increased costs. Utility Model Content

[0003] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a core-removing machine head for pith extraction, enabling multi-specification core extraction operations, improving efficiency, and reducing the core breakage rate.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a die head for a pith core extractor, including a disc, on which multiple push rods of different diameters are arranged in a circular array, and a threaded hole is opened in the center of the disc.

[0005] Preferably, the thickness of the disk is 15mm±10mm and the diameter is 130mm±50mm.

[0006] Preferably, the length of each of the plurality of push rods is 300mm ± 70mm.

[0007] Preferably, the number of push rods is nine.

[0008] Preferably, the diameters of the nine push rods, from smallest to largest, are: 8mm±3mm, 10mm±3mm, 12mm±3mm, 14mm±3mm, 16mm±3mm, 18mm±3mm, 20mm±3mm, 25mm±4mm, and 28mm±5mm.

[0009] Preferably, the diameter of the threaded hole is 16mm ± 5mm.

[0010] Preferably, the inner side of the push rod away from the disc is provided with a cutting knife structure for cutting through the outer shell of the pith.

[0011] Preferably, the slicing structure includes circular, elongated, or square protrusions.

[0012] The beneficial effects of this utility model are as follows: The die head for the pith core extraction machine provided by this utility model, by setting push rods of various diameter sizes on the disc, enables the pith core extraction machine to adapt to the core extraction operation of pith of different specifications without frequent parts replacement, thereby improving efficiency and reducing the core breakage rate. It reduces manual operation steps, lowers the labor intensity of operators, and makes pith processing easier and more convenient. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example:

[0018] like Figures 1-2 As shown, this utility model provides a die head for a pith core extraction machine, including a disc 1.

[0019] The thickness of disk 1 is 15mm ± 10mm, and the diameter is 130mm ± 50mm.

[0020] Multiple push rods 2 of varying diameters are arranged in a circular array on the disc 1. The push rods 2 can be welded and fixed to the disc 1. Specifically, the length of each push rod 2 is 300mm ± 70mm. The preferred number of push rods 2 is nine, thus accommodating the core extraction of pith of different diameters. The diameters of the push rods 2, from smallest to largest, are: 8mm ± 3mm, 10mm ± 3mm, 12mm ± 3mm, 14mm ± 3mm, 16mm ± 3mm, 18mm ± 3mm, 20mm ± 3mm, 25mm ± 4mm, and 28mm ± 5mm.

[0021] A threaded hole 3 is opened in the center of the disk 1, and the diameter of the threaded hole 3 is 16mm±5mm.

[0022] The disc 1 can be installed on the pith core extractor through the threaded hole 3.

[0023] In this embodiment, a cutting structure 4 is provided on the inner side of the end of the push rod 2 away from the disc 1 to facilitate cutting the outer shell of the pith. The cutting structure 4 is located on the inner side of the push rod 2 to prevent accidental injury to workers.

[0024] The slicing structure 4 includes protrusions in the form of circles, strips, squares, etc. The size of the slicing structure 4 is not limited, as long as it can effectively cut through the outer shell of the pith.
