Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of meat cutting equipment, and in particular to a feeding fixing device suitable for meat cutting, a meat rotary cutting device and a meat bevel cutting device. BACKGROUND

[0002] Meat generally refers to divided meat such as fish meat, poultry meat, beef and pork.

[0003] The meat rotary cutting device mainly comprises a rotary blade cutting device and a floating belt pressing device, and the floating belt pressing device generally comprises an upper belt and a lower belt. When the raw meat is placed on the lower belt and moves to the space between the upper belt and the lower belt, the upper belt is pressed on the raw meat, and the upper belt and the lower belt move simultaneously to push the raw meat to the direction of the cutting tool, so as to cut the raw meat. However, the floating belt pressing device is prone to deform the raw meat, and the distance between the raw meat and the cutting tool is far, so that the weight error is large when cutting small-size products.

[0004] Chinese patent CN120155961A discloses an intelligent bevel cutting machine, which comprises a belt conveying device and a bevel blade cutting device. The belt conveying device comprises an input belt, a conveying needle belt and an output belt arranged in sequence. The conveying needle belt has a large number of long needles on the surface of the belt. When the raw meat enters the conveying needle belt from the input belt, the long needles will be inserted into the raw meat, so that the raw meat and the conveying needle belt form a relatively firm connection, preventing the raw meat from sliding to ensure the cutting accuracy and stability. The anvil assembly is located between the conveying needle belt and the output belt. The blade driving mechanism drives two cutting blades to reciprocate and move relatively along the length direction of the blade. The two cutting blades cooperate with the anvil assembly to perform cutting operation. The conveying needle belt moves with the raw meat to the anvil and the cutting blade. After the raw meat is cut by the cutting blade and the anvil, it is output to the downstream process by the output belt. The conveying needle belt has the advantages of simple structure and low cost. However, the needles inserted into the meat can damage the surface of the product, and it is difficult to penetrate the meat surface when the meat surface is hard (for example, there are fascia or fish scales), resulting in large weight error of the cutting product. In addition, there is a risk of needle falling into the meat, which can scratch the operator during cleaning. SUMMARY

DETAILED DESCRIPTION

[0043] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

[0044] Figure 1 In the figure, the direction indicated by the arrow F is the conveying direction of the suction belt 3.

[0045] As Figure 1As shown, a feeding fixing device suitable for meat cutting is provided with a raw meat belt conveying mechanism on the support 2, which comprises an adsorption belt 3 wound between a first driving roller 41 and a plurality of first driven rollers, the middle part of the adsorption belt 3 is densely provided with adsorption holes 31, and the adsorption belt 3 is provided with a conveying area matching the conveying displacement of the raw meat R. The adsorption belt 3 is redirected at the upstream end U of the conveying area by a first driven roller 42, and is redirected at the downstream end D of the conveying area by a negative pressure adsorption box 1, which is fixed to the support 2. The top of the negative pressure adsorption box 1 is provided with an adsorption area, which is connected in communication with a negative pressure gas source 5 through a gas path; when the adsorption holes 31 covered by the raw meat R coincide with the adsorption area, the raw meat R is adsorbed and fixed on the adsorption belt 3 by negative pressure, so as to be cut by a cutting blade outside near the downstream end D of the conveying area of the adsorption belt 3.

[0046] The working principle of the feeding fixing device suitable for meat cutting is that negative pressure is generated by the negative pressure gas source 5 to make the raw meat tightly adhere to the adsorption belt 3 with the adsorption holes 31 coinciding with the adsorption area, and atmospheric pressure difference is utilized to realize stable fixation of the raw meat, so as to cut by the cutting blade in the cutting area near the adsorption belt 3.

[0047] The adsorption area comprises a main adsorption area and a secondary adsorption area, the main adsorption area is connected in communication with the negative pressure gas source 5 through a main gas path 55, the secondary adsorption area is connected in communication with the negative pressure gas source 5 through a secondary gas path, the main gas path 55 is provided with a main electric control valve, the secondary gas path is provided with a secondary electric control valve, the main electric control valve and the secondary electric control valve are respectively electrically connected with an electric control unit, and the electric control unit 6 controls the opening and closing of the main electric control valve and / or the secondary electric control valve through the signals of the outline and position of the raw meat R on the adsorption belt 3 output by the sensor 7.

[0048] As mentioned above, the number of the main adsorption area and the secondary adsorption area is set according to the outline of the raw meat to be cut.

[0049] When the outline of the raw meat R is large, the main adsorption area and the secondary adsorption area can be simultaneously in working state to adsorb the raw meat R more firmly; when the outline of the raw meat R is small, only the main adsorption area can be selected to be in working state. Alternatively, when the raw meat R is placed on the adsorption belt in a position deviating, the corresponding adsorption area can be selected to be in working state according to the deviated position of the raw meat. In this way, the adsorption area is divided into areas, which can not only ensure the adsorption and fixation of the raw meat and prevent displacement of the raw meat during cutting, but also save the gas source.

[0050] In some embodiments, the sensor 7 is a 3D vision scanning device, when the raw meat R is placed on the conveying area of the adsorption belt 3, the raw meat R is sent from the upstream end U of the conveying area to the downstream end D of the conveying area along with the running of the belt, when the raw meat R covers the position where the adsorption hole 31 coincides with the adsorption area, the raw meat R is adsorbed and fixed on the adsorption belt 3 by negative pressure, so as to implement cutting by the cutting blade near the outside of the downstream end D of the conveying area of the adsorption belt 3, that is Figure 1 the cutting blade cuts on the left side near the downstream end D of the conveying area of the adsorption belt 3.

[0051] As shown in Figures 2 to 5 , as a preferred mode, the adsorption area of the negative pressure adsorption box 1 includes a main adsorption area and two auxiliary adsorption areas, the main adsorption area is located in the middle, the auxiliary adsorption areas include a first auxiliary adsorption area and a second auxiliary adsorption area located on both sides of the main adsorption area, the first auxiliary adsorption area is connected to the negative pressure air source 5 through the first auxiliary air path 56, the second auxiliary adsorption area is connected to the negative pressure air source 5 through the second auxiliary air path, the first auxiliary air path 56 is provided with the first auxiliary electric control valve 51 electrically connected with the electric control unit 6, and the second auxiliary air path 57 is provided with the second auxiliary electric control valve 52 electrically connected with the electric control unit 6. Among them, the negative pressure air source 5 can adopt an adsorption fan, or a vacuum pump, or other vacuum generating devices.

[0052] When the negative pressure air source 5 adopts an adsorption fan, the main air path 55 can also cancel the main electric control valve, and the adsorption belt is in a ventilation state during conveying the raw meat R. The adsorption fan is preferably fixed with a silencer 53 and a filter 54, and the filter 54 is installed between the air path and the adsorption fan. The raw meat usually has blood water and surface debris, and the installation of the filter 54 can effectively remove and clean the blood water and debris. The filter 54 is to ensure that clean air enters the negative pressure air source, prolonging the service life of the negative pressure air source.

[0053] As shown in Figures 2 to 5 , the negative pressure adsorption box 1 includes a box body 11 and a cover plate 12, the cover plate 12 is arranged on the top of the box body 11, the top of the box body 11 is provided with a main adsorption groove 101, a first auxiliary adsorption groove 102 and a second auxiliary adsorption groove 103, the main adsorption groove 101 is provided with a main ventilation hole 111 connected with the main air path 55, the first auxiliary adsorption groove 102 is provided with a first auxiliary ventilation hole 112 connected with the first auxiliary air path 56, and the second auxiliary adsorption groove 103 is provided with a second auxiliary ventilation hole 113 connected with the second auxiliary air path 57.

[0054] The cover plate 12 is provided with a main suction hole area 121, a first auxiliary suction hole area 122 and a second auxiliary suction hole area 123. The main suction hole area 121 corresponds to the main suction groove 101 to form a main suction area. The first auxiliary suction hole area 122 corresponds to the first auxiliary suction groove 102 to form a first auxiliary suction area. The second auxiliary suction hole area 123 corresponds to the second auxiliary suction groove 103 to form a second auxiliary suction area.

[0055] In some embodiments, the main suction groove 101 is provided in a T shape, and the first auxiliary suction groove 102 and the second auxiliary suction groove 103 are provided in a one-stroke shape extending longitudinally and obliquely. The shape of the main suction groove 101, the shape of the first auxiliary suction groove 102 and the shape of the second auxiliary suction groove 103 mainly depend on the profile of the raw meat R to be cut. The above-mentioned feeding fixing device suitable for meat cutting is mainly used for conveying raw meat R such as fish (the part after removing the head) and chicken breast. Of course, the main suction groove 101 can also be provided in a triangular shape, and the top angle of the triangular shape faces the rear side of the box body 11.

[0056] The top of the box body 11 is provided with a counterbore, and the cover plate 12 is placed in the counterbore together with the top surface of the box body 11 to form a supporting surface. The front side 105 of the box body 11 is rounded and transitions to the supporting surface to form a wedge-shaped corner 104. The suction belt 3 is redirected at the wedge-shaped corner 104. The angle of the wedge-shaped corner 104 is α, which is an acute angle. If the wedge-shaped corner 104 is too small, the suction belt is prone to arching when passing through the top of the negative pressure suction box 1, which causes the raw meat R to be not fixed by suction at this position, and the cutting of the meat is not convenient. If the wedge-shaped corner 104 is too large, it is not conducive to the redirection of the belt.

[0057] In some embodiments, the front side 105 is provided as a plane. Such a negative pressure suction box 1 with the front side 105 provided as a plane is mainly suitable for meat rotary cutting equipment.

[0058] As shown in Figure 6 In some other embodiments, the front side 105 of the box body 11 of the negative pressure suction box 1 is provided as a curved surface. This structure can prevent the belt from arching at the top of the negative pressure suction box 1. If the belt arches at the top of the negative pressure suction box 1, the suction force of the suction hole 31 covered by the raw meat R will decrease, which affects the cutting effect of some meat cutting equipment. When such a negative pressure suction box 1 with the front side 105 provided as a curved surface is applied to meat oblique cutting equipment, the raw meat is more stably fixed by suction, which avoids movement of the raw meat during cutting, and in turn avoids uneven cutting caused by movement of the meat.

[0059] In the feeding fixing device suitable for meat cutting, the negative pressure suction box 1 can not only play a role of changing the direction of the suction belt 3, but also form a supporting surface with the top surface of the box body 11 to support the suction belt 3 and the raw meat R, thereby providing support for the cutting of the raw meat R. Meanwhile, the negative pressure suction box 1 is connected to the negative pressure air source 5 through the air path, and then cooperates with the suction belt to fix the raw meat R for cutting.

[0060] The edge of the first driving roller 41 is provided with a plurality of transmission protrusions 411 arranged in the circumferential direction, and the edge of the suction belt 3 is provided with a plurality of transmission holes 32 matched with the transmission protrusions 411. When the first driving roller 41 rotates, the transmission protrusions 411 are inserted into the transmission holes 32 to move the suction belt 3. Preferably, the outer circumferential surfaces of the two edges of the first driving roller 41 are respectively provided with a circle of transmission protrusions 411, and the two edges of the suction belt 3 are provided with a row of transmission holes 32 corresponding to the two circles of transmission protrusions 411.

[0061] Next, the working process of the feeding fixing device suitable for meat cutting is described by way of example.

[0062] As shown in Figure 1 When the raw meat to be cut is fish (with the head removed), the fish is usually placed along the conveying direction of the belt at the upstream end U of the conveying area, and the fish is located at the middle of the suction belt 3. When the fish on the suction belt 3 runs through the 3D visual scanning device, the 3D visual scanning device can detect the profile and position of the fish on the suction belt 3 and convert them into an electrical signal and send them to the electric control unit 6. After receiving the signal, the electric control unit 6 plans a cutting scheme and controls the negative pressure air source 5, the main electric control valve, the first auxiliary electric control valve 51 and the second auxiliary electric control valve 52 to open. When the fish is transported to the suction hole 31 and overlaps with the suction area, the fish is suctioned and fixed on the suction belt 3, and the suction belt continues to move to the downstream end to cooperate with the cutting knife to cut the fish meat. The cut fish meat part enters the finished meat belt conveying mechanism. When the fish is gradually cut to the tail part, the electric control unit 6 controls the first auxiliary electric control valve 51 and the second auxiliary electric control valve 52 to close, and only the main suction area is communicated with the negative pressure air source 5. In this way, the tail part of the fish can be firmly suctioned, and the purpose of saving the air source can be achieved.

[0063] The feeding fixing device suitable for meat cutting has the following advantages:

[0064] (1) The feeding fixing device suitable for meat cutting uses negative pressure suction to fix the raw meat on the suction belt, which non-destructively fixes the raw meat on the suction belt, avoids the squeezing damage of traditional clamps to meat, and maintains the integrity of the meat.

[0065] (2) The feeding fixing device suitable for meat cutting has strong adaptability, and can be used for irregularly shaped meat blocks such as chicken breast, chicken leg, pork and whole fish (or fish fillets).

[0066] (3) The suction belt, negative pressure suction box, and filter components of the feeding fixture suitable for meat cutting are easy to clean and meet food safety standards. They can reduce mechanical contact, reduce the risk of contamination, and produce hygienic and safe products.

[0067] (4) The feeding fixture suitable for meat cutting can be manufactured according to a custom design, and can adjust parameters such as the number of adsorption areas and the size and shape of the negative pressure adsorption box according to the different types of raw meat (such as beef, pork, poultry) and the size of the outline.

[0068] (5) The feeding fixing device suitable for meat cutting is used to fix the raw meat, and the working efficiency is high.

[0069] (6) When the feeding fixing device suitable for meat cutting is used on the meat cutting equipment, the raw meat is fixed firmly, which enables the meat cutting equipment to cut accurately, improve the meat yield and reduce waste.

The conveyor belt is wound around a fixed support member 83 at the upstream end and is wound around a second driven roller 822 at the downstream end.

[0071] The frame 8 is also provided with the aforementioned feed fixture suitable for meat cutting. The raw meat belt conveyor mechanism of the meat cutting feed fixture is arranged upstream of the finished meat belt conveyor mechanism 82. A cutting gap C is provided between the raw meat belt conveyor mechanism and the finished meat belt conveyor mechanism 82. The rotary blade cutting device 81 is arranged in the cutting gap C to horizontally cut the raw meat R into finished meat. The "horizontal" here refers to the direction perpendicular to the conveying direction of the raw meat belt conveyor mechanism.

[0072] The rotating blade cutting device 81 includes a rotating blade and a blade driving motor. This structure is well known to those skilled in the art and will not be described in detail here.

[0073] like Figure 8 As shown, since the cutting gap C between the raw meat belt conveyor mechanism and the finished meat belt conveyor mechanism 82 is relatively small, it is only necessary for the rotating rotary blade to pass through. Therefore, the meat blocks or slices cut from the raw meat R by the rotary blade will be directly moved from the adsorption belt 3 of the raw meat belt conveyor mechanism to the belt of the finished meat belt conveyor mechanism 82, and generally no other transfer structure is required.

[0074] Compared with the prior art, the meat rotary cutting device has the following advantages: due to the adoption of the negative pressure adsorption technology, the raw meat can be quickly and non-destructively fixed on the adsorption belt, the raw meat R is prevented from being squeezed and deformed, the integrity of the meat quality is maximally maintained, and the finished meat quality is better and the quality is better. Meanwhile, the adsorption area of the feeding and fixing device is closer to the rotary blade cutting device 81, that is, when the raw meat R is adsorbed and fixed, the raw meat R is closer to the cutting edge, and can be used for cutting small-size products, and the cutting error of the products is greatly reduced.

[0075] As shown in Figure 9 A meat oblique cutting device, a rack 8 is provided with an obliquely arranged blade cutting device 84 and a finished meat belt conveying mechanism 82, the finished meat belt conveying mechanism 82 comprises a conveying belt wound between a third driving roller and a plurality of third driven rollers, the conveying belt is redirected at an upstream end by a fixed support 83 and redirected at a downstream end by a third driven roller; the rack 8 is also provided with the above-mentioned feeding and fixing device suitable for meat cutting, the raw meat belt conveying mechanism of the feeding and fixing device suitable for meat cutting is arranged at an upstream position of the finished meat belt conveying mechanism 82, a cutting gap C is arranged between the raw meat belt conveying mechanism and the finished meat belt conveying mechanism 82, and the obliquely arranged blade cutting device 84 is arranged at the cutting gap C to transversely and obliquely cut the raw meat R into finished meat. The cutting range of "oblique cutting" is 15°-90° (that is, the angle between the blade edge plane and the horizontal plane during cutting), and when cutting at 90°, it can be considered as straight cutting.

[0076] As shown in Figure 10 Generally, a meat supporting plate assembly 85 and an anvil plate assembly 86 are arranged between the cutting gap C, the meat supporting plate assembly 85 is fixedly installed with the rack 8, the meat supporting plate assembly 85 is used for supporting the raw meat R, and the anvil plate assembly 86 is used for cooperating with the oblique blade cutting. The raw meat R moves from the adsorption belt 3 of the raw meat belt conveying mechanism to the meat supporting plate assembly 85 and the anvil plate assembly 86, the oblique blade cuts the raw meat R into a flaky or block shape on the anvil plate assembly 86, and the cut meat block or piece moves to the belt of the finished meat belt conveying mechanism 82.

[0077] The oblique blade cutting device 84 has been disclosed in the patent CN120155961A, and will not be repeated here.

[0078] When the feeding and fixing device suitable for meat cutting disclosed by the present application is applied to an oblique cutting machine, the input belt and the conveying needle belt thereof can be replaced. Due to the adoption of the negative pressure adsorption technology, the raw meat can be quickly and non-destructively fixed on the adsorption belt, the needle of the conveying needle belt is prevented from being inserted into the meat to damage the product surface, even the raw meat with a relatively hard surface can be non-destructively fixed on the adsorption belt 3, the raw meat is fixed firmly during cutting, the cutting is uniform, and the cutting error of the products is greatly reduced.

[0079] The above merely describes preferred embodiments of the present application, and is not used to limit the present application, any modification, equivalent replacement and improvement within the spirit and principle of the present application should be included in the protection scope of the present application.
