Centre gripping punching formula red date stoner

Technical Field

The invention belongs to the field of agricultural product processing, and relates to a clamping and punching type red date pit removing machine.

Background

The deep processing of the red dates can effectively improve the added value of red date products, and is a mainstream development trend of the red date industry in the future. The pit removal of the red dates is a necessary pretreatment procedure for the deep processing of the red dates, and the quality of the deep processing products of the red dates is directly affected by the operation effect of the pit removal machine of the red dates. The invention summarizes the research current situation of the red date pit remover, analyzes the problems of the existing red date pit remover, and designs a clamping punching type red date pit remover.

Chinese patent No. CN102210477B discloses a full-automatic red date pit removing machine, the equipment is powered by a motor, and automatic, batch and rapid pit removing of red dates is realized by utilizing the cooperation between a red date holder, a centralizer, a pit removing pipe and a pit removing rod. But compared with a stepping motor, the common motor has lower reliability and low denucleation efficiency, and the upper part of the denucleation rod piece is not provided with protective measures, so that the motor is more easily damaged.

When in actual use, the method comprises the following steps: the device is driven by a stepping motor, the main motions are intermittent working of the jujube carrying crawler belt and intermittent reciprocating linear motion of the stoning mechanism, the jujube carrying crawler belt is driven by the stepping motor I (6) through a crawler belt driving wheel (11), the stoning mechanism converts rotary motion of the stepping motor II (12) into reciprocating linear motion through a connecting rod mechanism, the two stepping motors operate in a coordinated mode, and the stoning mechanism is controlled to finish the jujube stoning operation in each intermittent period of the jujube carrying crawler belt.

When the device is operated: during operation, red dates are poured into the storage bin (2), the stepping motor I (6) drives the crawler driving wheel (11) to rotate for a certain angle at regular intervals, meanwhile, the crawler driving wheel (11) drives the date carrying chain plate to move forward for one station, the red dates roll on the date carrying crawler inclined plane of the storage bin (2) and fall into the red date holder (26) by themselves, redundant red dates are removed through the hairbrush roller (10), and meanwhile, the red dates falling into the red date holder (26) are righted and pressed. The stoning mechanism is driven by a stepping motor II (12), intermittent up-and-down reciprocating stoning movement is realized through a connecting rod mechanism, and the stoning mechanism finishes one-time up-and-down reciprocating movement during each intermittent stop period of the jujube-carrying crawler belt. After the red date is pressed into the red date holder (26) through the brush roller (10), the annular spring (27) at the first-stage clamping (28) of the red date holder (26) is firstly propped up, the posture of the red date is adjusted to be in a vertical state, the red date keeps in a vertical state and continues to move downwards until being clamped by two layers of the red date holder (26), the date carrying chain plate (9) moves to the position of the nuclear punching rod (20), the nuclear punching rod (20) moves back and forth, the date pits are punched, the date pits fall into the date pit trough (8) below, the date carrying chain plate (9) moves to the position of the date pressing rod (19), the date pressing rod (19) moves downwards to prop up the bottom of the red date holder (26), and the date after the pit removal is pressed out falls into the nuclear removal date trough (7), so that the whole date pit removal process is completed.

The invention has the outstanding advantages that:

1. the motors used in the invention are stepping motors and are provided with the control panel (4), so that the stoning quality is high, and the stoning efficiency is stable.

2. The top of the bin (2) is provided with the brush roller (10), so that redundant red dates can be removed; also has the functions of strengthening and compacting the red dates in the red date holder (26).

3. The buffer spring (23) is arranged in the pit removing mechanism, so that the damage of the edge part of the pit punching rod (20) can be prevented, and the stress of the pit removing mechanism when the pit removing mechanism is contacted with the red date can be buffered, and the unnecessary damage to the jujube peel can be prevented.

4. The red date holder (26) and the pressing plate (25) are integrated, and the red date holder can directly remove the pits of red dates of different types and sizes by replacing the pressing plate (25).

5. According to the invention, the red date clamp holder (26) is two-stage clamping, the first-stage clamping (28) plays a guiding role, and the annular spring (27) is externally arranged to prevent the axis of the red date from being not vertical when the red date is pressed into the clamp holder; the second stage clamping (29) plays a role in clamping and compacting, and prevents the red dates from being carried out during the pit removal.
