DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Reference Figure 1-Figure 6 A meat cutting device is shown.

[0021] The meat cutting device comprises a support frame 100, which is responsible for providing a stable supporting platform for the entire device.

[0022] The meat cutting device includes an advancement mechanism 200, which is responsible for conveying the product 500 from one place to another in a straight line;

[0023] The meat cutting device includes a pulling low-temperature freezing mechanism 300, which is responsible for pulling the product 500 to both sides when the meat is stopped. The effect of pulling is to make the product 500 flat, and the purpose of low-temperature freezing is to cooperate with pulling, because if you want to pull the special product 500 such as fresh meat flat, the clamping and grabbing methods that can be thought of will inevitably cause squeezing of the product 500, which will make the product 500 uneven and reduce the value of the product 500. Therefore, the design of the present invention uses two contact arms, and uses a matching refrigeration component to reduce the temperature of the product contact surface 700 of the contact arm, and freezes the surface of the product 500 through the low temperature effect of the product contact surface 700, and makes the product 500 adhere to the product contact surface 700 through the low temperature effect, and then pulls the product 500 to both sides through the two contact arms, so as to achieve the effect that the product 500 is not wrinkled or piled up, and avoid squeezing the product 500.

[0024] At the same time, low-temperature freezing can freeze the surface moisture of the product 500 and make the surface of the meat hard. This state is conducive to the subsequent segmentation, making the segmentation process smoother. At the same time, it can reduce the temperature of the knife, avoid damage to the meat quality, and increase the value of the product 500.

[0025] Specifically, in the design of the present invention, the pulling low-temperature freezing mechanism 300 includes a first contact arm 301 and a second contact arm 302, and the first contact arm 301 and the second contact arm 302 are symmetrically arranged. The first contact arm 301 and the second contact arm 302 are provided with matching refrigeration components to cool down the temperature of the two, so that the temperature of the product contact surface 700 of the first contact arm 301 and the second contact arm 302 is reduced. The first contact arm 301 and the second contact arm 302 are also provided with a matching screw drive mechanism 303, and the screw drive mechanism 303 allows the first contact arm 301 and the second contact arm 302 to be crimped on both sides of the product 500, and the surface of the product 500 is frozen by the low temperature effect of the product contact surface 700, and the product 500 is adhered to the product contact surface 700 by the low temperature effect, and then the product 500 is pulled to both sides by the first contact arm 301 and the second contact arm 302.

[0026] Among them, the product 500 adheres to the product contact surface 700 because there is moisture on the surface of the product 500. When the product contact surface 700 is pressed on the product 500, the moisture will adhere to the low-temperature product contact surface 700 after freezing. Moreover, this adhesion is not too strong. After retreating to a certain position, it can be separated from the product 500, and will not affect the separation from the product 500 after the product 500 is divided. For this reason, it should be noted that when the screw drive mechanism 303 drives the first contact arm 301 and the second contact arm 302 to pull the product 500 to both sides, the retreat distance should not be too large, and 1 cm is the best, so as to avoid the first contact arm 301 and the second contact arm 302 from separating from the product 500. However, after the division, the screw drive mechanism 303 should drive the first contact arm 301 and the second contact arm 302 to retreat to a certain distance to ensure that the two can be separated from the product 500. Of course, in this embodiment, the first contact arm 301 and the second contact arm 302 should be directly retreated to the initial position, that is, the position with the largest separation.

[0027] It should be noted that a contact feedback system should be provided on the screw drive mechanism 303 to ensure that the first contact arm 301, the second contact arm 302 and the product 500 are in close contact. The contact feedback system may be a visual monitoring system, which may include components such as a camera and an image processing unit, for capturing image information between the first contact arm 301, the second contact arm 302 and the product 500, and analyzing the image information to determine whether the contact is close. If the contact is close, the visual monitoring system may send a feedback signal to the screw drive mechanism 303 through a control signal to stop the first contact arm 301 and the second contact arm 302. In addition to this method, a pressure monitoring system may also be used.

[0028] In the design of the present invention, the refrigeration component can be a refrigeration plate, and the refrigeration effect can be achieved by using the refrigeration plate, or the refrigeration effect can be achieved by filling cold air into the hollow contact arm.

[0029] In the design of the present invention, the first contact arm 301 and the second contact arm 302 have the same structure, and they are not of the traditional integrated structure, but are composed of a plurality of flat structures and small arms 304 arranged at intervals along the vertical direction. In this way, a gap can be left between each small arm 304. In coordination with this, the design of the present invention also has a cutting and pulling mechanism 400, which is provided with a reciprocating blade 401. After the product 500 is pulled and the surface is frozen, the product 500 can be divided. It has a plurality of horizontally arranged blades 401, which can cut the product 500 into pieces. The gaps between the small arms 304 are the cutting paths reserved for the blades 401. Such a design allows the product 500 to be pulled flat from both sides, and a pulling effect can also be formed in the vertical direction, which can further improve the value of the product 500. At the same time, the surface tension of the product 500 increases after being pulled, which makes the object easier to cut.

[0030] In the design of the present invention, the cutting and pulling mechanism 400 also includes multiple groups of cylinders 402, each group of cylinders 402 corresponds to a blade 401, which is used to drive the blade 401 to move and cut the product 500. More specifically, the cylinder 402 is provided with an end 403, and the blade 401 has a knife holder 404 at both ends. The knife holders 404 at both ends of the blade 401 are inserted into the end 403 of the corresponding group of cylinders 402, and the two knife holders 404 can move between the two end 403. A polarization motor 405 is installed on at least one knife holder 404. The polarization motor 405 can be used to vibrate the blade 401, forming a repeated back and forth cutting effect, making the segmentation smoother and improving efficiency.

[0031] In the design of the present invention, the small arm 304 includes a fixed plate 601, and two movable semicircular movable large plates 602 are arranged on the side of the fixed plate 601. The fixed plate 601 is provided with a matching large plate movable groove 603. Each movable large plate 602 is also provided with a movable semicircular movable small plate 604. The movable large plate 602 is provided with a matching small plate movable groove 605. The movable small plate 604 is provided with a plane, which is the above-mentioned product contact surface 700, wherein the movable small plate 604 can rotate in the small plate movable groove 605, and the movable large plate 602 can rotate in the large plate movable groove 603. This design makes the product contact surface 700 not a whole horizontal surface, but a discrete plurality of small contact surfaces composed of planes on a plurality of movable small plates 604. Moreover, since the movable large plate 602 can rotate, and the movable small plates 604 can rotate relative to the movable large plate 602, the degree of freedom of each small contact surface is high, which can ensure that each small contact surface is in full contact with the side of the product 500, and ensure the pulling effect and the freezing effect on the surface of the product 500, thereby further improving the quality and reliability of the product 500.

[0032] Specifically, the above-mentioned fixed plate 601 is composed of two parts, the upper and lower parts, the movable large plate 602 is sandwiched in the middle, and the movable large plate 602 is provided with a first limiting screw, which is inserted into the movable large plate 602 to the movable slot 603 of the large plate, and the movable slot 603 of the large plate is provided with a matching first limiting slot. Correspondingly, the movable large plate 602 is also composed of two parts, the upper and lower parts, which sandwich the movable small plate 604 in the middle, and the movable small plate 604 is also provided with a second limiting screw 606 which is inserted into the movable slot 605 of the small plate, and the movable slot 605 of the small plate is provided with a matching second limiting slot 607. The limiting screws provided on both the movable large plate 602 and the movable small plate 604 are used to limit the maximum rotation angle of the movable large plate 602 and the movable small plate 604.

[0033] On this basis, if the refrigeration component uses a refrigeration sheet, the semiconductor refrigeration sheet can be installed at the end of the fixed plate 601, the refrigeration end is attached to the fixed plate 601, and a duct and a suction motor are set to discharge the heat released by the heating end; the fixed plate 601 can transfer the cold energy to the movable large plate 602 and the movable small plate 604 in sequence to reduce the temperature of the product contact surface 700. If it is cold air, it needs to be connected to the fixed plate 601. The fixed plate 601 adopts a hollow design, and the temperature of the fixed plate 601 is reduced by circulating cold air, and the temperature of the movable small plate 604 is reduced by energy transfer, thereby reducing the temperature of the product contact surface 700. Both of these require that the small arm 304 is made of a material with good thermal conductivity as a whole.

[0034] In the design of the present invention, the advancing mechanism 200 can adopt a roller conveyor or a belt conveyor. Both types of conveyors can meet this demand and have good effects in practical applications.

[0035] A roller conveyor is a common conveying device, which is composed of a plurality of rollers. The rollers are rotated by a driving system, thereby driving the product 500 to move forward. A belt conveyor is another common conveying device, which is mainly composed of a belt and a driving system. The belt is driven by the driving system to move forward, thereby moving the product 500 forward. Both types of forwarding mechanisms 200 can meet the requirements of the present invention and can effectively convey the product 500 from one place to another for the next step of processing.

[0036] Considering the characteristics of fresh meat, the forward mechanism 200 will inevitably be contaminated. In order to facilitate the cleaning of the forward mechanism 200, a roller conveyor can be used as a preferred embodiment. Because of the design of the roller, the cleaning work can be made easier, for example, it can be directly scrubbed with a detergent and then rinsed with clean water.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
