Description

Technical Field

[0001] The invention relates to the technical field of meat pressing plate equipment, in particular to a cold fresh meat pressing plate forming machine and a forming method thereof. Background Art

[0002] Chilled fresh meat refers to fresh meat that has been produced through strict veterinary quarantine and rapid cooling of animal carcasses after slaughter, so that the carcass temperature drops to 0-4°C within 24 hours. The temperature is then kept within the range of 0-4°C during subsequent processing, circulation and sales. This greatly reduces the number of initial bacteria, and because it is always kept at low temperatures, its sanitary quality is significantly improved, making it popular among consumers.

[0003] Since the cut fresh meat has no fixed shape, it is inconvenient to pack and transport it. Therefore, the fresh meat is shaped by a press machine before packing. However, the following disadvantages are common in the actual operation:

[0004] 1. In order to prevent the cold meat from sticking to the placement plate (used for placing the cold meat) and the lower pressing plate of the pressing machine, and to prevent the dust on the pressing machine from directly contacting the cold meat, the staff needs to wrap the cold meat with plastic film before pressing the plate. The operation is as follows: the staff first spreads the plastic film flat, places the cold meat on the plastic film, and wraps the cold meat with the plastic film. The wrapping should not be too tight to prevent the plastic film from being damaged due to the squeezing of the cold meat during the pressing process of the pressing machine. The operation is troublesome and requires the staff to have certain experience. In addition, the staff needs to contact the cold meat (wrap the plastic film) before pressing the plate. The staff has a long contact time with the cold meat during the whole pressing process. Even if they wear gloves, their hands will still feel uncomfortable after working for a short time.

[0005] 2. Since the shape of the fresh meat after cutting is irregular, and the pressing plate of the traditional pressing machine is flat, the density of each part of the fresh meat will be different during the pressing process, resulting in obvious color difference and poor quality of the final product. In addition, during the subsequent cooking process of consumers, the parts with lower density and those with higher density will have different degrees of flavor and taste.

[0006] In view of the above problems, we propose a cold fresh meat press plate forming machine and a forming method thereof. Summary of the invention

[0066] The winding mechanism 8 includes a first guide hole 812 opened on the placement table 4, and the first guide hole 812 divides the placement table 4 into two parts, one part is the placement frame 41, and the other part is the placement plate 42 fixed in the center of the placement frame 41, and the two long sides of one side of the placement plate 42 are provided with a first circular groove 81, and the other side is provided with a second circular groove 82 on the long side located at the top, and a third circular groove 83 is provided on the lower long side of the inner wall of the side of the placement frame 41 close to the second circular groove 82, and a first rotating rod 84 is rotatably arranged in the first circular groove 81, the second circular groove 82, and the third circular groove 83, and a second guide hole 85 is opened on the L plate 33 close to the third circular groove 83, and a second rotating rod 86 is installed in the second guide hole 85, and the side of the placement frame 41 close to the second rotating rod 86 is provided. A third rotating rod 88 is fixed by the support frame 87. One end of the plastic film 61 is fixed to the paper tube 6, and the other end passes through the first rotating rod 84 at the position of the first circular groove 81, the first rotating rod 84 at the position of the second circular groove 82, the first rotating rod 84 in the third circular groove 83, the second rotating rod 86 in the second guide hole 85, and the third rotating rod 88 on the support frame 87 in sequence, and is finally located above the placement frame 41.

First, it approaches each other, and synchronously drives the clamping block 81112 to approach each other, clamping one end of the plastic film 61, and then continues on the guide plate 8101. The plastic film 61 moves in the slide rail 8104, driving the plastic film 61 to cover the top of the cold fresh meat. When it moves to the other side of the slide rail 8104, under the guidance of the inclined groove 8105 on the arc plate 8102 on the other side, the clamping blocks 81112 at one end of the plastic film 61 release the plastic film 61 in turn, and the clamping blocks 81112 close to the third rotating rod 88 re-clamp the middle part of the plastic film 61 to wrap the subsequent cold fresh meat again. The guide bar 8106 and the inclined groove 8105 at the end of the inclined groove 8105 facing the bottom surface can guide the connecting rod 8117 to move in a regular trajectory to ensure the stable operation of the equipment.

[0072] A cutting mechanism 9 is installed on the placement table 4. After the pressing of a single piece of fresh meat is completed, the cutting mechanism 9 cuts off the plastic film 61 covering the fresh meat. The cutting mechanism 9 includes a square bar 91 installed on the guide plate 8101. The square bar 91 is located above the side of the square bar 91 close to the third rotating rod 88. A laser emitter 92 is installed on the square bar 91. An energy absorbing plate 93 is installed on the placement frame 41. The energy absorbing plate 93 is arranged opposite to the laser emitter 92.

[0076] S1: The staff limits the position of the plastic film 61 through the support mechanism 7, and then places one end of the plastic film 61 above one side of the placement table 4 through the winding mechanism 8, and drives the clamping block 81112 to clamp one end of the plastic film 61 by turning on the second servo motor 8111. At this time, the plastic film 61 covers the top surface of the placement table 4, and the preliminary setting of the equipment is completed;

[0077] S2: Place the cold fresh meat on the plastic film 61 of the placement table 4, start the translation mechanism 5, and drive the placement table 4 and the cold fresh meat to move to the bottom of the pressing plate 2;

[0078] S3: Turn on the second servo motor 8111, and the single group of clamping blocks 81112 drives the plastic film 61 to cover the top of the cold fresh meat. When the covering is completed, the cutting mechanism 9 is triggered, and at the same time, another group of single group of clamping blocks 81112 re-clamps the plastic film 61;

[0079] S4: The hydraulic rod 12 is turned on. The hydraulic rod 12 drives the pressing plate 2 to approach the placing table 4 through the docking seat 15. The elastic cover 21 on the bottom of the pressing plate 2 and the steel balls 22 in the elastic cover 21 press the cold fresh meat.

[0080] S5: After the cold meat is pressed, the hydraulic rod 12 drives the pressing plate 2 to reset through the docking seat 15, and the supporting mechanism 7 moves the placement table 4 and the pressed cold meat away from the bottom of the pressing plate 2;

[0081] S6: A layer of plastic film 61 is pre-laid on the bottom of the box where the fresh meat is placed, and the pressed fresh meat and the plastic film 61 attached to the top are placed in the box, and the fresh meat is pressed once.
