Description

Technical Field

[0001] This utility model relates to the field of meat cutting equipment technology, and in particular to a negative pressure adsorption box in a feeding and fixing device suitable for meat cutting. Background Technology

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

[0003] Meat slicing equipment mainly consists of a rotary blade cutting device and a floating belt clamping device. The floating belt clamping device typically includes an upper belt and a lower belt. When the raw meat is placed on the lower belt and moves between the upper and lower belts, the upper belt presses down on the raw meat. The simultaneous movement of the upper and lower belts propels the raw meat towards the cutting blade for cutting. However, the floating belt clamping device is prone to deforming the raw meat and is relatively far from the blade edge, resulting in significant weight errors when used to cut small-sized products.

[0004] Chinese utility model patent CN120155961A discloses an intelligent oblique slicing machine, including a belt conveyor and an oblique blade cutting device. The belt conveyor includes an input belt, a conveyor needle belt, and an output belt arranged in sequence. The surface of the conveyor needle belt has a large number of long needles. When the raw meat enters the conveyor needle belt from the input belt, these long needles insert into the raw meat, forming a relatively firm connection between the raw meat and the conveyor needle belt, preventing the raw meat from slipping and ensuring the cutting accuracy and stability. The anvil assembly is located between the conveyor needle belt and the output belt. The blade drive mechanism drives two cutting blades to reciprocate and move relative to each other along the length of the blades. The two cutting blades cooperate with the anvil assembly to perform the cutting operation. The movement of the conveyor needle belt carries the raw meat towards the anvil and cutting blades. After the raw meat has been cut by the cutting blades and the anvil, it is output to the downstream process by the output belt. The advantages of conveyor needle belts are simple structure and low cost. However, the needles can easily damage the surface of the product when inserted into the meat. Moreover, it is difficult to penetrate the meat when the surface is hard (such as with fascia or fish scales), resulting in a large error in the weight of the cut product. In addition, there is a risk that the needles may fall out and enter the meat, which may scratch the operator during cleaning.

[0005] Therefore, it is necessary to improve the feeding and fixing device of the existing meat cutting equipment, and correspondingly, the components of the feeding and fixing device also need to be innovated. Utility Model Content

[0006] In view of this, the technical problem to be solved by this utility model is to provide a negative pressure adsorption box, which can be used in conjunction with the adsorption belt to not only change the direction of the adsorption belt, but also to quickly and non-destructively adsorb and fix the raw meat.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0008] A negative pressure adsorption box is used in a feeding and fixing device suitable for meat cutting. The top of the negative pressure adsorption box is provided with an adsorption area. The negative pressure adsorption box includes a box body and a cover plate. The cover plate is disposed on the top of the box body. The cover plate and the top surface of the box body together form a supporting surface. The front side of the box body transitions to the supporting surface with rounded corners and forms a wedge-shaped corner for deflecting the adsorption band. An adsorption groove is opened on the top of the box body. The adsorption groove has a vent hole for communicating with a negative pressure air source. The cover plate has an adsorption hole area. The adsorption hole area and the adsorption groove correspond to form the adsorption area.

[0009] Preferably, the adsorption region includes a main adsorption region and a secondary adsorption region, and the main adsorption region and the secondary adsorption region are respectively connected to the negative pressure gas source.

[0010] Preferably, the main adsorption region is located in the middle, and the secondary adsorption region includes a first secondary adsorption region and a second secondary adsorption region located on both sides of the main adsorption region, wherein the first secondary adsorption region and the second secondary adsorption region are respectively connected to the negative pressure gas source.

[0011] Preferably, the adsorption groove includes a main adsorption groove, a first secondary adsorption groove, and a second secondary adsorption groove, and the main adsorption groove, the first secondary adsorption groove, and the second secondary adsorption groove are respectively provided with the ventilation holes;

[0012] The cover plate has a main adsorption hole area, a first secondary adsorption hole area, and a second secondary adsorption hole area. The main adsorption hole area and the main adsorption groove correspond to form the main adsorption area. The first secondary adsorption hole area and the first secondary adsorption groove correspond to form the first secondary adsorption area. The second secondary adsorption hole area and the second secondary adsorption groove correspond to form the second secondary adsorption area.

[0013] Preferably, the main adsorption groove is T-shaped, and the first and second auxiliary adsorption grooves are respectively configured as a straight line extending longitudinally and inclined.

[0014] Preferably, the top of the box body is provided with a countersunk hole, and the cover plate is placed in the countersunk hole and is flush with the top surface of the box body.

[0015] Preferably, the top of the box body is provided with a slot for disassembling and prying open the cover plate, and the slot is located on one side of the countersunk hole.

[0016] Preferably, the wedge-shaped corner is an acute angle.

[0017] Preferably, the front side is configured as a plane.

[0018] Preferably, the front side surface is configured as a curved surface.

[0019] After adopting the above technical solution, the beneficial effects of this utility model are:

[0020] The negative pressure adsorption box disclosed in this utility model is used in a feeding and fixing device suitable for meat cutting. This feeding and fixing device is equipped with an adsorption belt, and the negative pressure adsorption box works in conjunction with the adsorption belt. The negative pressure adsorption box includes a box body and a cover plate. The cover plate and the top surface of the box body together form a supporting surface, which supports the adsorption belt and raw meat. The front side of the box body transitions to the supporting surface with rounded corners, forming a wedge-shaped corner for redirecting the adsorption belt. An adsorption groove is formed on the top of the box body, and the adsorption groove has a vent hole for connecting to a negative pressure air source. The cover plate has an adsorption hole area, which corresponds to the adsorption groove to form an adsorption area. After the adsorption area is connected to the negative pressure air source, it can quickly and non-destructively adsorb and fix the raw meat. Furthermore, let the angle of the wedge-shaped corner be α, where α is an acute angle. If the wedge-shaped corner is too small, the adsorption belt is prone to arching when passing the top of the negative pressure adsorption box, leading to air leakage. Consequently, the raw meat cannot be adsorbed and fixed at this point, making meat cutting difficult. If the wedge-shaped corner is too large, it is not conducive to belt deflection. Furthermore, the front side of the negative pressure adsorption box is made into an arc surface. This structure can prevent the belt at the top of the negative pressure adsorption box from arching and causing air leakage, thus making the raw meat more firmly adsorbed and fixed.

[0021] In this invention, the adsorption area is configured as a main adsorption area and a secondary adsorption area. The main adsorption area is connected to a negative pressure gas source via a main gas path, and the secondary adsorption area is connected to a negative pressure gas source via a secondary gas path. A main electrically controlled valve is installed on the main gas path, and a secondary electrically controlled valve is installed on the secondary gas path. Both valves are electrically connected to an electronic control unit. The electronic control unit controls the opening and closing of the main and / or secondary electrically controlled valves based on the contour and position signals of the raw meat on the adsorption belt, output by a 3D vision scanning device. The 3D vision scanning device scans the contour and position of the raw meat and converts it into electrical signals, which are then transmitted to the electronic control unit. The electronic control unit controls the opening and closing of the main and / or secondary electrically controlled valves to control the working state of the main and secondary adsorption areas. When the scanned outline of the raw meat is large, both the main adsorption area and the secondary adsorption area can be in working state simultaneously to ensure a more secure adsorption of the raw meat. When the outline of the raw meat is small, only the main adsorption area can be selected to be in working state. Alternatively, when the raw meat is placed off-center, the corresponding adsorption area can be selected to be in working state based on the off-center position of the raw meat. This segmented setting of adsorption areas ensures that the raw meat is adsorbed and fixed, preventing displacement during cutting, while also avoiding weak adsorption caused by air leakage in the adsorption areas, and saving air supply.

[0022] In this invention, the top of the box is provided with a slot for prying open the cover, so that the cover can be removed from the countersunk hole at the top of the box for easy cleaning. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0036] like Figures 2 to 5 As shown, the negative pressure adsorption box 1 is used for Figure 1 In the feeding and fixing device suitable for meat cutting, the top of the negative pressure adsorption box 1 is provided with an adsorption area; the negative pressure adsorption box 1 includes a box body 11 and a cover plate 12. The cover plate 12 is located on the top of the box body 11, and the cover plate 12 and the top surface of the box body 11 together form a supporting surface. The front side 105 of the box body 11 transitions to the supporting surface with rounded corners and forms a wedge-shaped corner 104 for adsorption belt reversal; an adsorption groove is opened on the top of the box body, and a vent hole is opened in the adsorption groove for communicating with the negative pressure air source 5. An adsorption hole area is opened on the cover plate 12, and the adsorption hole area and the adsorption groove correspond to form an adsorption area.

[0037] The adsorption belt 3 changes direction at the wedge-shaped corner 104. Let the angle of the wedge-shaped corner 104 be α, where α is an acute angle. If the wedge-shaped corner 104 is too small, the adsorption belt is prone to arching and causing air leakage when it passes the top of the negative pressure adsorption box 1. As a result, the raw meat R cannot be adsorbed and fixed at this point, making it difficult to cut the meat. If the wedge-shaped corner 104 is too large, it will be detrimental to the belt turning.

[0038] like Figures 1 to 5As shown, in a preferred embodiment, the adsorption zone includes a main adsorption zone and a secondary adsorption zone, both of which are connected to a negative pressure gas source. Specifically, the main adsorption zone is connected to the negative pressure gas source 5 via a main gas path 55, and the secondary adsorption zone is connected to the negative pressure gas source 5 via a secondary gas path. A main electrically controlled valve can be installed in the main gas path 55, and a secondary electrically controlled valve can be installed in the secondary gas path. Both the main and secondary electrically controlled valves are electrically connected to an electronic control unit 6. The electronic control unit 6 controls the opening and closing of the main and / or secondary electrically controlled valves based on signals from the sensor 7 indicating the contour and position of the raw material meat R on the adsorption belt 3.

[0039] In some embodiments, the adsorption area of ​​the negative pressure adsorption box 1 includes a main adsorption area and two secondary adsorption areas. The main adsorption area is located in the middle, and the secondary adsorption areas include a first secondary adsorption area and a second secondary adsorption area located on both sides of the main adsorption area. The first secondary adsorption area is connected to the negative pressure gas source 5 through a first secondary gas passage 56, and the second secondary adsorption area is connected to the negative pressure gas source 5 through a second secondary gas passage 57. The first secondary gas passage 56 is provided with a first secondary electrically controlled valve 51 electrically connected to the electronic control unit 6, and the second secondary gas passage 57 is provided with a second secondary electrically controlled valve 52 electrically connected to the electronic control unit 6. The negative pressure gas source 5 can be an adsorption fan, a vacuum pump, or other vacuum generating device.

[0040] The number of primary and secondary adsorption regions is set according to the outline of the raw meat to be cut.

[0041] When the outline of the raw meat R is large, both the main adsorption area and the secondary adsorption area can be in working state simultaneously to ensure a more secure adsorption of the raw meat R. 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 in a slightly off-center position on the adsorption belt, the corresponding adsorption area can be selected to be in working state based on the off-center position of the raw meat. This segmented setting of the adsorption areas ensures that the raw meat is firmly adsorbed and fixed, preventing displacement during cutting, while also avoiding air leakage in the adsorption areas that would lead to weak adsorption, and saving air supply.

[0042] like Figure 3 and Figure 4As shown, in some embodiments, the adsorption groove includes a main adsorption groove 101, a first secondary adsorption groove 102, and a second secondary adsorption groove 103. The main adsorption groove 101, the first secondary adsorption groove 102, and the second secondary adsorption groove 103 are each provided with vent holes; that is, the main adsorption groove 101 has a main vent hole 111 connected to the main air passage 55, the first secondary adsorption groove 102 has a first secondary vent hole 112 connected to the first secondary air passage 56, and the second secondary adsorption groove 103 has a second secondary vent hole 113 connected to the second secondary air passage 57. The cover plate 12 has a main adsorption hole area 121, a first secondary adsorption hole area 122, and a second secondary adsorption hole area 123. The main adsorption hole area 121 corresponds to the main adsorption groove 101 to form a main adsorption area, the first secondary adsorption hole area 122 corresponds to the first secondary adsorption groove 102 to form a first secondary adsorption area, and the second secondary adsorption hole area 123 corresponds to the second secondary adsorption groove 103 to form a second secondary adsorption area.

[0043] In some embodiments, a countersunk hole is provided on the top of the box body 11, and a cover plate 12 is placed in the countersunk hole. The cover plate 12 is flush with the top surface of the box body 11 and together they form a supporting surface.

[0044] In some embodiments, the front side 105 is configured as a plane. This negative pressure adsorption box 1 with the front side 105 configured as a plane is mainly suitable for meat rotary cutting equipment.

[0045] like Figure 6 As shown, in some other embodiments, the front side 105 of the negative pressure adsorption box 1 body 11 is set as an arc surface. This structure can prevent the belt at the top of the negative pressure adsorption box 1 from arching. If the belt at the top of the negative pressure adsorption box 1 arches, it will cause air leakage between the adsorption holes 31 and the adsorption area covered by the raw meat R, resulting in a decrease in adsorption force and affecting the cutting effect of some meat cutting equipment. When this negative pressure adsorption box 1 with the front side 105 set as an arc surface is applied to meat slicing equipment, the raw meat is adsorbed and fixed more firmly, avoiding movement of the raw meat during cutting, and thus avoiding uneven cutting caused by meat movement.

[0046] In a feeding and fixing device suitable for meat cutting, the negative pressure adsorption box 1 not only serves to redirect the adsorption belt 3, but also forms a supporting surface together with the top surface of the cover plate 12 and the box body 11 to support the adsorption belt 3 and the raw meat R, providing support for the cutting of the raw meat R. At the same time, the negative pressure adsorption box 1 is connected to the negative pressure air source 5 through the air passage, and then cooperates with the adsorption belt to fix and adsorb the raw meat R for cutting.

[0047] The top of the box body 11 is provided with a slot 106 for prying open the cover plate 12, and the slot 106 is located on one side of the countersunk hole. This makes it easy to remove the cover plate 12 from the countersunk hole at the top of the box body 11 for easy cleaning of the cover plate.

[0048] like Figure 3 As shown, in some embodiments, the main adsorption groove 101 is configured as a T-shape, and the first secondary adsorption groove 102 and the second secondary adsorption groove 103 are respectively configured as a longitudinally extending and inclined straight line. The shape of the main adsorption groove 101, the first secondary adsorption groove 102, and the second secondary adsorption groove 103 mainly depends on the contour of the raw meat R to be cut. The above-mentioned feeding and fixing device suitable for meat cutting is mainly used for conveying raw meat R such as fish (the part after removing the fish head) and chicken breast. Of course, the main adsorption groove 101 can also be configured as a triangle, with the apex of the triangle facing the rear side of the box body 11.

[0049] Figure 1 In the diagram, the direction indicated by arrow F is the direction of transport by the adsorption belt 3.

[0050] like Figure 1 As shown, a feeding and fixing device suitable for meat cutting is provided. A raw meat belt conveyor mechanism is provided on the support 2. The raw meat belt conveyor mechanism includes an adsorption belt 3 wound between a first driving roller 41 and several first driven rollers. The adsorption belt 3 has adsorption holes 31 densely distributed in the middle. The adsorption belt 3 is provided with a conveying area that matches the conveying displacement of the raw meat R. The adsorption belt 3 is wound around a first driven roller 42 at the upstream end U of the conveying area and redirected at a negative pressure adsorption box 1 at the downstream end D of the conveying area. The negative pressure adsorption box 1 is fixed to the support 2. An adsorption area is provided on the top of the negative pressure adsorption box 1. The adsorption area is connected to a negative pressure air source 5 through an air passage. 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 that it can be cut by the cutting blade on the outside near the downstream end D of the conveying area of ​​the adsorption belt 3.

[0051] The working principle of this utility model of a feeding and fixing device suitable for meat cutting is as follows: negative pressure is generated by negative pressure air source 5, so that the raw meat is tightly attached to the adsorption belt 3 where the adsorption hole 31 coincides with the adsorption area. The atmospheric pressure difference is used to achieve stable fixing of the raw meat, so that the cutting blade can cut it in the cutting area close to the adsorption belt 3.

[0052] In some embodiments, sensor 7 is a 3D vision scanning device. When the raw meat R is placed in the conveying area of ​​the adsorption belt 3, the raw meat R is conveyed from the upstream end U of the conveying area to the downstream end D of the conveying area as the belt moves. When the raw meat R covers the position where the adsorption hole 31 overlaps with the adsorption area, the raw meat R is adsorbed and fixed on the adsorption belt 3 by negative pressure, so that it can be cut by the cutting blade on the outside near the downstream end D of the conveying area of ​​the adsorption belt 3. Figure 1 The cutting blade makes a cut on the left side of the downstream end D of the adsorption belt 3 conveying area.

[0053] When the negative pressure air source 5 uses an adsorption fan, the main air path 55 can also omit the main solenoid valve. During the transport of raw meat R, the main adsorption area remains ventilated. Preferably, the adsorption fan is equipped with a silencer 53 and a filter 54, with the filter 54 installed between the air path and the adsorption fan. Raw meat typically contains blood and surface debris; installing the filter 54 effectively removes and promptly cleans away these substances. The filter 54 ensures clean air enters the negative pressure air source, extending its service life.

[0054] The first drive roller 41 has multiple circumferentially arranged transmission protrusions 411 on its edge, and the adsorption belt 3 has multiple transmission holes 32 that match the transmission protrusions 411 on its edge. When the first drive roller 41 rotates, the transmission protrusions 411 insert into the transmission holes 32 and move the adsorption belt 3. Preferably, the outer circumferential surfaces of the two edges of the first drive roller 41 are respectively provided with circular transmission protrusions 411, and the two edges of the adsorption belt 3 are provided with rows of transmission holes 32 corresponding to the two circular transmission protrusions 411.

[0055] The following example illustrates the working process of the feeding and fixing device suitable for meat cutting:

[0056] like Figure 1 As shown, when the raw material to be cut is fish (with the head removed), the front part of the fish is usually wider than the tail part. At the upstream end U of the conveyor area, the fish is placed along the conveyor direction and positioned in the middle of the adsorption belt 3. After the fish on the adsorption belt 3 passes the 3D vision scanning device, the device detects the outline and position of the fish on the adsorption belt 3 and converts it into an electrical signal, which is then sent to the electronic control unit 6. Upon receiving this signal, the electronic control unit 6 plans the cutting scheme and controls the negative pressure air source 5, the main electronic control valve, and the first auxiliary electronic control valve 5. When the first and second auxiliary electric control valves 51 and 52 are opened, the fish is transported to the adsorption hole 31 and overlaps with the adsorption area. The fish is then adsorbed and fixed on the adsorption belt 3 by negative pressure. The adsorption belt continues to move downstream to feed and cooperate with the cutting blade to cut the fish meat. The cut fish meat enters the finished meat belt conveyor. 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, leaving only the main adsorption area connected to the negative pressure air source 5. This ensures that the tail part of the fish is firmly adsorbed and also saves air source.

[0057] The feeding and fixing device for meat cutting of this utility model has the following advantages:

[0058] (1) The feeding and fixing device suitable for meat cutting uses negative pressure adsorption to fix the raw meat on the adsorption belt. This non-destructive fixing of the raw meat on the adsorption belt avoids the squeezing damage to the meat caused by traditional clamps and maintains the integrity of the meat.

[0059] (2) The feeding and fixing device suitable for meat cutting is highly adaptable and can adhere to irregularly shaped meat pieces such as chicken breast, chicken leg meat, pork, whole fish (or fish fillets), beef, etc.

[0060] (3) The components of the feeding and fixing device suitable for meat cutting, such as the adsorption belt, negative pressure adsorption box, and filter, are easy to clean and meet food safety standards. This reduces mechanical contact, minimizes the risk of contamination, and ensures the produced products are hygienic and safe.

[0061] (4) The feeding and fixing device suitable for meat cutting can be customized and manufactured. It can adjust the number of adsorption areas, the size and shape of the negative pressure adsorption box and other parameters according to the different types of raw meat (such as beef, pork and poultry) and their outline size.

[0062] (5) The feeding and fixing device suitable for meat cutting is highly efficient when used to fix raw meat.

[0063] (6) When a feeding and fixing device suitable for meat cutting is applied to meat cutting equipment, the meat cutting equipment can cut accurately, improve the meat yield, and reduce waste because the raw meat is fixed firmly.

[0064] Figure 7 A meat slicing device is shown, wherein the frame 8 is provided with a rotating blade cutting device 81 and a finished meat belt conveyor 82; the finished meat belt conveyor 82 includes a conveyor belt wound between a second driving roller 821 and a plurality of second driven rollers, the conveyor belt being redirected at the upstream end by a fixed support member 83 and at the downstream end by a second driven roller 822.

[0065] The frame 8 is also equipped with the aforementioned feeding and fixing device suitable for meat cutting. The raw meat belt conveyor mechanism of the feeding and fixing device suitable for meat cutting 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 at the cutting gap C to laterally cut the raw meat R into finished meat. Here, "lateral" means perpendicular to the direction of conveying the raw meat belt conveyor mechanism.

[0066] The aforementioned rotary blade cutting device 81 includes a rotary blade and a blade drive motor. This structure is well known to those skilled in the art and will not be described in detail here.

[0067] like Figure 8 As shown, since the cutting gap C between the raw meat belt conveyor and the finished meat belt conveyor 82 is relatively small, it is only necessary for the rotating blade to pass through. Therefore, the meat chunks or slices cut by the rotating blade from the raw meat R will move directly from the adsorption belt 3 of the raw meat belt conveyor to the belt of the finished meat belt conveyor 82, generally without the need for other transfer structures.

[0068] Compared with existing technologies, the meat rotary cutting equipment has the following advantages: Due to the use of negative pressure adsorption technology, it can quickly and non-destructively fix the raw meat onto the adsorption belt, preventing the raw meat R from being squeezed and deformed, thus maximizing the integrity of the meat and resulting in better quality finished meat. Simultaneously, the adsorption area of ​​the feeding and fixing device is closer to the rotating blade cutting device 81, meaning that when adsorbing and fixing the raw meat R, it ensures that the raw meat R is closer to the blade edge, enabling the cutting of small-sized products and significantly reducing cutting errors.

[0069] like Figure 9 As shown, a meat slicing device includes a frame 8 with an oblique blade cutting device 84 and a finished meat belt conveyor 82. The finished meat belt conveyor 82 includes a conveyor belt wound between a third driving roller and several third driven rollers. The conveyor belt is redirected at its upstream end by a fixed support 83 and at its downstream end by a third driven roller. The frame 8 also includes the aforementioned feeding and fixing device suitable for meat cutting. The raw meat belt conveyor of the feeding and fixing device is located upstream of the finished meat belt conveyor 82. A cutting gap C is provided between the raw meat belt conveyor and the finished meat belt conveyor 82. The oblique blade cutting device 84 is arranged at the cutting gap C to obliquely slice the raw meat R into finished meat. The cutting range of the above-mentioned "oblique cutting" is from 15° to 90° (i.e., the angle between the blade cutting plane and the horizontal plane during cutting). When cutting at 90°, it can be considered a straight cut.

[0070] like Figure 10 As shown, a meat support plate assembly 85 and a cutting board assembly 86 are typically installed between the cutting gaps C. The meat support plate assembly 85 is fixedly installed with the frame 8. The meat support plate assembly 85 is used to support the raw meat R, and the cutting board assembly 86 is used to cooperate with the cutting of the angled blade. The raw meat R moves from the suction belt 3 of the raw meat belt conveyor to the meat support plate assembly 85 and the cutting board assembly 86. The angled blade cuts the raw meat R into slices or chunks on the cutting board assembly 86. The cut meat chunks or slices are moved onto the belt of the finished meat belt conveyor 82.

[0071] The oblique blade cutting device 84 has been disclosed in Chinese Utility Model Patent CN120155961A, and will not be described in detail here.

[0072] When the feeding and fixing device for meat cutting disclosed in this utility model is applied to a slitting machine, it can replace the input belt and conveyor needle belt. Due to the use of negative pressure adsorption technology, the raw meat can be quickly and non-destructively fixed on the adsorption belt, avoiding the needles of the conveyor needle belt from inserting into the meat and damaging the product surface. Even raw meat with a hard surface can be non-destructively fixed on the adsorption belt 3. During cutting, the raw meat is firmly fixed, the cutting is uniform, and the cutting error of the product is greatly reduced.

[0073] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
