Technical Field

The invention relates to the technical field of poultry processing, in particular to an automatic gizzard and clausena lansium grinding and scraping machine and an assembly line applying the same.

Background

On present poultry workshop production line, the manual work is scraped duck gizzard yellow skin with the cutter, generally needs two sets of people, and a set of special duck gizzard that comes to grind, another special duck gizzard that scrapes of group, required operating personnel are many, and processing is wasted time and energy. This inventor is the patent of prior application, and the patent number is CN201811259050.6, in the patent of title for an automatic gizzard of opening of duck gizzard, washing and gizzard production device, designed an automatic gizzard of opening of duck gizzard, washing and gizzard production device that basic full automatization realized, discover in actual production, the gizzard mechanism of last position though can effectively get rid of duck gizzard yellow skin, little duck gizzard yellow skin of esophagus position, the gizzard wheel of arranging relatively is difficult to scrape. Consequently, redesigned this equipment, design a more excellent automatic machine of scraping of birds gizzard yellow skin, collect and grind gizzard and scrape gizzard function in an organic whole, can effectively get rid of the yellow skin of chicken gizzard or duck gizzard esophagus position, it is better to remove the yellow skin effect, need not arrange the personnel again completely and carry out secondary processing.

Disclosure of Invention

The automatic poultry gizzard and yellow skin grinding and scraping machine is based on the improvement of the prior automatic duck gizzard opening, cleaning and gizzard grinding production device, integrates the gizzard grinding and scraping functions, can effectively remove yellow skin at the positions of chicken gizzards or duck gizzards, has a better yellow skin removing effect, and does not need to arrange personnel for secondary processing.

The technical scheme of the invention is as follows:

the utility model provides an automatic machine of scraping that grinds of birds gizzard clausena lansium, includes frame, grinds gizzard subassembly and friction gyro wheel, the friction gyro wheel is vertical to be placed, and its outer edge is equipped with a plurality of birds gizzard and imports and exports, wear first rotation axis in the middle of the friction gyro wheel, first rotation axis both ends assembly is in the frame, wherein one end of first rotation axis is connected with first motor, first motor assembly is on the motor fixed plate in the frame outside, and rotation through the first rotation axis of drive drives the friction gyro wheel and rotates forward. At least one gizzard grinding assembly is arranged on each of the two sides of the friction roller, the positions of the two sides of the gizzard grinding assemblies are not overlapped, the gizzard grinding assemblies are connected to the frame and comprise a gizzard grinding wheel and a second motor, the gizzard grinding wheel is driven by the second motor, the rotating direction of the gizzard grinding wheel is opposite to that of the friction roller, and when the friction roller rotates forwards, the gizzard grinding wheel can contact with the poultry gizzard yellow skin and conduct reverse grinding scraping on the poultry gizzard yellow skin. Through the gizzard grinding assembly arranged on the two sides of the friction roller, the left and right faces of the poultry gizzard placed on the inlet and outlet of the friction roller can be respectively ground and scraped, the positions of the two sides of the gizzard grinding assembly are not overlapped, only the gizzard grinding assembly on one side is in contact with the poultry gizzard at the same time, under the action of reverse grinding and scraping of the gizzard grinding wheel, the poultry gizzard is close to one side of the gizzard grinding wheel and can be pulled out by the gizzard grinding wheel, so that yellow skin at the middle esophagus position is exposed, the gizzard grinding wheel is convenient to grind and scrape, and the poultry gizzard yellow skin is beneficial to being cleaned.

Further, grind the gizzard subassembly and still include first fixing base, first connecting plate, second connecting plate and second axis of rotation, first fixing base both ends are equipped with first connecting plate, be equipped with the bearing on the first connecting plate, worn the second axis of rotation in the middle of the bearing, it is equipped with the second connecting plate to grind gizzard wheel both ends, the second connecting plate is also worn in the second axis of rotation. So, first fixing base second axis of rotation relatively rotates, and the gizzard wheel and the second connecting plate that link to each other with the second axis of rotation grind when scraping the yellow skin on poultry gizzard surface, can follow the automatic transform height of poultry gizzard surface shape, do not hinder the poultry gizzard.

Preferably, be equipped with the spring holder in the frame, it leans on to be equipped with the slot on the second connecting plate of last position to grind the gizzard subassembly, be connected with the spring between slot and the spring holder, spring strength should not be too high, and under the spring pulling force effect, the gizzard wheel can be more closed poultry gizzard surface and grind and scrape the yellow skin, under the prerequisite of not hindering the poultry gizzard, improves and grinds and scrape efficiency.

As above automatic birds gizzard yellow skin mill scrape machine, the friction gyro wheel still is equipped with birds gizzard location mouth between adjacent birds gizzard is imported and exported, birds gizzard location mouth size is less than 1/2 of birds gizzard expansion area, when the gizzard wheel pulling birds gizzard moves to its place one side, birds gizzard part that increases can block in birds gizzard location mouth, plays the effect of fixed birds gizzard on the one hand, on the other hand makes birds gizzard surface and grinds and keeps a suitable distance between the gizzard wheel, makes the gizzard wheel steadily roll birds gizzard surface, does not injure birds gizzard.

Preferably, two channels of poultry gizzards are arranged at intervals between adjacent gizzard assemblies to avoid one poultry gizzard from being contacted by the two gizzard assemblies simultaneously.

As above automatic gizzard yellow skin grinding and scraping machine, still be equipped with long board brush subassembly and short board brush subassembly at last gizzard subassembly rear, long board brush subassembly and short board brush subassembly are located the friction gyro wheel both sides respectively to be connected with the frame through the support respectively. The secondary gizzard scraping operation can be carried out on the poultry gizzards processed by the gizzard grinding wheel so as to ensure that the poultry gizzard yellow skin is thoroughly cleaned.

Further, the long plate brush assembly is located the opposite side of last gizzard grinding assembly, the brush hair part length on the short plate brush assembly is shorter than the long plate brush assembly, the rear end of the short plate brush assembly is flush with the rear end of the long plate brush assembly. The poultry gizzard is ground gizzard subassembly back through last one, and the center can be partial to and grind gizzard subassembly one side, through the preceding half section of long board brush subassembly, can pull back poultry gizzard center to the central point of friction gyro wheel and put, and the operation is scraped to poultry gizzard surface residual yellow skin in step to the back long board brush subassembly of being convenient for and short board brush subassembly.

As above automatic machine of scraping of rubbing of birds' gizzard yellow skin, long board brush subassembly includes second fixing base and long brush, second fixing base and frame fixed connection, the outer plane of long brush is on a parallel with the outer plane of friction gyro wheel.

Further, the short board brush subassembly includes third fixing base, short brush, bracing piece and spring, short brush assembles on the third fixing base, the third fixing base articulates on the bracing piece, spring one end is kept away from short brush one side with the third fixing base and is linked to each other, and the other end is connected with the bracing piece, the bracing piece is directly or is connected with the frame through the connecting piece.
