Description

Technical Field

[0001] This invention relates to the field of meat cutting technology, specifically to a cutting device for packaging fresh meat. Background Technology

[0002] Before being sold, meat needs to be cut into different pieces based on its quality and economic value. For example, the front section has more fascia and is suitable for mincing, the middle section contains high-value parts such as ribs and tenderloin, and cutting them separately can maximize the commodity price. The rear section has a high yield of meat, but the meat quality of different parts is different, so they can be processed differently. Generally speaking, the front, middle and rear sections of meat are distinguished by the position of the bones. The cutting position of the circular saw is marked by light, and the position of the animal carcass is manually adjusted.

[0003] In existing factories, meat is first cut into large pieces, and then manually separated into different grades and values. In the step of cutting into large pieces, a conveyor belt is generally used, along with two circular saws, to perform the cutting action. The cutting positions are marked with laser lines, and the cutting positions need to be adjusted manually. Existing large factories will classify livestock according to size and send them to different cutting stations to match the specifications of the cutting equipment. However, even after the livestock are classified by size, there will still be individual differences and other reasons, resulting in some differences in the position and distance of the bones. Therefore, the cutting process relies heavily on human experience and eyesight to determine the cutting positions. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a cutting device for packaging fresh meat, which can effectively solve the problem of how to increase the accuracy of cutting position in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a cutting device for packaging fresh meat, including a conveyor roller, a closed-loop drive device, and two saw blades, and further comprising: Several clamping and positioning components are installed on a closed-loop drive device and synchronously driven by the closed-loop drive device to follow a directional circular path. They are distributed on both sides of the conveyor roller conveyor and are capable of clamping and releasing the forelimbs and hindlimbs of livestock carcasses. A linear drive device is provided for adjusting the carcass position after clamping the forelimbs and hindlimbs.

[0006] Furthermore, the clamping and adjusting assembly includes a connecting plate and two elastic supports fixedly installed on the moving end of the closed-loop driving device. The elastic supports are fixedly installed below the connecting plate. A slide table is slidably connected to the top of the connecting plate. A servo motor is fixedly installed on the top of the slide table. A gear connecting group is fixedly connected to the output end of the servo motor.

[0007] Furthermore, two clamping plates are symmetrically fixedly connected to the gear connection group, and the servo motor drives the two clamping plates to perform clamping or releasing actions through the gear connection group; An electric push rod is fixedly installed on the top of the connecting plate. The electric push rod drives the slide to control the position of the servo motor and related clamping components.

[0008] Furthermore, the closed-loop drive device includes two fixed frames and two belts and closed-loop slide rails of the same shape and path. A drive shaft is connected between the two belts and the drive shaft is rotatably mounted between the two fixed frames. The two closed-loop slide rails are fixedly mounted on one side of the fixed frames by a support frame and are located between the two belts. A slider is slidably mounted on the closed-loop slide rail, and the elastic support is fixedly mounted on the slider. The top of the fixing frame is fixedly connected to a guide plate at an angle to guide the fresh meat after it has been cut to slide down.

[0009] Furthermore, a friction contact strip is fixedly connected to the bottom of the connecting plate, and the bottom of the friction contact strip is connected to the belt drive.

[0010] Furthermore, the two saw blades are symmetrically distributed on both sides of the conveyor rollers and are positioned above the gap between the conveyor rollers and the closed-loop drive device, enabling them to cut the animal carcass and adjust the cutting position within the gap space between the conveyor rollers and the closed-loop drive device.

[0011] Furthermore, a linear motor is fixedly installed on the top of the conveyor roller, and an automatic gripper is fixedly installed on the bottom fixed side of the linear motor. The moving end of the linear motor can convey the animal carcass in the direction of the automatic gripper. After the forelimbs or hindlimbs of the carcass completely abut against the automatic gripper, the two grippers of the automatic gripper rotate downward to the horizontal, losing their obstruction effect on the carcass.

[0012] Furthermore, lifting and transfer components are respectively provided at the gaps on both sides of the conveyor roller and the closed-loop circulation drive equipment, including an electric push rod II and a push plate fixedly installed on the top of the electric push rod II, which can lift the cut fresh meat part and slide it outward.

[0013] The technical solution provided by this invention has the following advantages compared with the known prior art: 1. The equipment uses conveyor rollers instead of the traditional conveyor belt in the middle position. The clamping and adjusting components on both sides are synchronously driven by closed-loop circulation drive equipment, which directly saves the installation space of two conveyor belts and effectively reduces the overall area occupied by the equipment. At the same time, the clamping and adjusting components can realize the automatic adjustment of the carcass position, eliminating the need for manual adjustment of the carcass posture. The closed-loop circulation drive equipment can synchronously drive the carcass conveying, reducing manual operation links, lowering labor costs, and solving the problems of large space occupation by conveyor belts and cumbersome manual adjustment in traditional slitting methods, thereby improving the efficiency of the overall slitting process.

[0014] 2. The closed-loop circulating drive system with synchronous operation on both sides ensures the carcass faces the saw blade in a straight position, avoiding uneven cutting caused by carcass tilting during the slitting process. The clamping and adjusting components can precisely adjust the carcass position. Combined with the adjustable position of the saw blade within the gap between the conveyor rollers and the closed-loop circulating drive system, the slitting position can be precisely positioned according to the cutting needs of different livestock carcasses. This ensures that the slitting fresh meat segments meet the requirements for subsequent fine segmentation, guarantees product cutting consistency, and enhances the economic value of fresh meat.

[0015] 3. After slitting, the slid portion of the conveyor roller can tilt downwards, allowing the middle section of fresh meat to slide smoothly onto the subsequent conveyor belt, achieving automatic transfer of the middle section. The lifting and transfer components on both sides can lift the front and rear sections of fresh meat after slitting, turn them outwards, and slide them down along the guide plate. In conjunction with the conveyor belt, the front and rear sections can be orderly diverted and transferred to different fine-tuning stations. In addition, the closed-loop circulation drive equipment can be driven by belt or chain. Belts have strong anti-fouling ability and are suitable for the hygiene requirements of livestock cutting, while chains have stronger conveying capacity. The choice can be made flexibly according to the factory scale and actual needs, improving the practicality of the equipment.

[0016] 4. By cooperating with the automatic gripper and the clamping and adjusting component, the cutting position is adjusted based on the position of the carcass limb joints. There is no need for a complex vision positioning system. While ensuring sufficient cutting accuracy, the manufacturing and maintenance costs of the equipment are greatly reduced. The clamping and adjusting actions of the clamping and adjusting component are automatically driven by the power equipment, making operation convenient and reducing the difficulty of manual operation. The setting of the elastic support allows the clamping and adjusting component to pass smoothly through the arc part of the closed-loop track, ensuring the stability of equipment operation, reducing the occurrence of failures, reducing the later maintenance costs, and making it more suitable for use in factories of all sizes.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] The present invention will be further described below with reference to embodiments.

[0022] Reference Figures 1 to 7Example: A cutting device for packaging fresh meat includes a conveyor roller 1, a closed-loop drive device 2, and two saw blades 4. The two saw blades 4 are symmetrically distributed on both sides of the conveyor roller 1 and are located above the gap between the conveyor roller 1 and the closed-loop drive device 2. They are capable of cutting livestock carcasses, and the cutting position can be adjusted within the gap space between the conveyor roller 1 and the closed-loop drive device 2. A number of clamping and adjusting components 3 are installed on the closed-loop drive device 2 and are synchronously driven by the closed-loop drive device 2 to follow a closed-loop circular path. They are distributed on both sides of the conveyor roller 1 and are capable of clamping and releasing the forelimbs and hindlimbs of the livestock carcass. A linear drive device is provided for adjusting the position of the carcass after clamping the forelimbs and hindlimbs.

[0023] The cutting of livestock is roughly divided into two steps. The first step is to cut the carcass into three segments after the initial cutting. The second step is to manually refine the three segments of the coarse carcass to maximize its economic value. After the carcass is cut, the carcass is placed on the conveyor roller 1 near the middle. The forelegs and hind legs of the carcass are held by the clamping and adjusting components 3 on both sides. The carcass is transported by the closed-loop circulation drive device 2. The conveyor roller 1 provides rolling support for the carcass. As the closed-loop circulation drive device 2 is driven, the carcass passes through two saw blades 4 and is cut into three segments: front, middle and rear.

[0024] After the clamping and adjusting component 3 clamps the forelimbs and hindlimbs of the carcass, the position of the carcass can be adjusted. The closed-loop circulation drive device 2, which operates synchronously on both sides, allows the carcass to face the saw blade 4 in a straight position, ensuring a relatively straight cutting position. In addition, with the adjustment of the carcass position, the cutting position can be accurately determined. Unlike the traditional cutting method, the conveyor roller 1 replaces the conveyor belt in the middle position, and the clamping and adjusting component 3, which is synchronously driven by the closed-loop circulation drive device 2 on both sides, replaces the conveyor belts on both sides. After the cutting is completed, the middle section of fresh meat on the conveyor roller 1 can be transferred by the conveyor belt, while the front and rear sections on the clamping and adjusting component 3 can be transferred by other conveyor belts after being released and transported to different work stations for further manual fine cutting.

[0025] By adopting the above-mentioned conveying and cutting methods, two sections of conveyor belts can be eliminated, and the position of the carcass can be automatically adjusted, reducing manual labor and saving space. In particular, the section of conveyor roller 1 after cutting can be inclined downward to ensure that the middle section can slide onto the conveyor belt and then be transferred to the manual work station.

[0026] Specifically, the clamping and adjusting assembly 3 includes a connecting plate 301 and two elastic supports 303 fixedly installed on the moving end of the closed-loop drive device 2. The elastic supports 303 are fixedly installed below the connecting plate 301. A slide table 304 is slidably connected to the top of the connecting plate 301. A servo motor 305 is fixedly installed on the top of the slide table 304. A gear connecting group 307 is fixedly connected to the output end of the servo motor 305. Two clamping plates 306 are symmetrically fixedly connected to the gear connecting group 307. Figure 7 As shown, this is one arrangement of gears inside the gear connecting assembly 307. Two clamping plates 306 are symmetrically distributed on both sides of the gear connecting assembly 307, moving closer or further apart synchronously. The servo motor 305 can drive the two clamping plates 306 to perform clamping or releasing actions through the gear connecting assembly 307. An electric push rod 308 is fixedly installed on the top of the connecting plate 301. The electric push rod 308 drives the slide table 304 to control the position of the servo motor 305 and related clamping components.

[0027] The clamping of the animal carcass relies on two rotatable clamps 306, powered by a servo motor 305. Through the transmission of the gear connection group 307, the two symmetrical clamps 306 clamp and release the forelimbs or hindlimbs of the carcass in a symmetrical manner. When it is necessary to adjust the position of the carcass, the electric push rod 308 provides power to push the clamps 306 that are clamping the forelimbs or hindlimbs to move, thereby adjusting the position of the carcass.

[0028] Among them, the electric push rods 308 can be distributed only on one side of the closed-loop cycle drive device 2, or distributed on both sides of the closed-loop cycle drive device 2. When distributed on one side, after the clamping plate 306 on that side rotates and clamps the forelimbs or hindlimbs of the carcass, the electric push rods 308 on the other side push or pull back the slide table 304 to adjust the position of the carcass. This method can roughly complete the adjustment of the position of the carcass and can also reduce the number of electric push rods 308 required. In small factories, if the animal hides are not cleaned well and are sticky, this method is not suitable. The most stable way to adjust the position of the carcass is to distribute the electric push rods 308 on both sides. The electric push rods 308 on both sides move synchronously. When one side is pulled back, the other side is pushed to adjust the position of the carcass.

[0029] Specifically, the closed-loop drive device 2 includes two fixed frames 201, two belts 202 of the same shape and path, and a closed-loop slide rail 203. The two belts 202 are connected by a drive shaft, which is rotatably mounted between the two fixed frames 201. The two closed-loop slide rails 203 are fixedly mounted on one side of the fixed frame 201 by a support frame, and the two closed-loop slide rails 203 are located between the two belts 202. A slider 204 is slidably mounted on the closed-loop slide rail 203, and an elastic support 303 is fixedly mounted on the slider 204. A guide plate 205 is inclinedly and fixedly connected to the top of the fixed frame 201 to guide the cut fresh meat to slide down.

[0030] Furthermore, a friction contact strip 302 is fixedly connected to the bottom of the connecting plate 301, and the bottom of the friction contact strip 302 is connected to the belt 202 for transmission.

[0031] Two belts 202, positioned on either side of the conveyor roller conveyor 1, provide power to the drive connecting plate 301. Two closed-loop slide rails 203, also positioned on either side of the conveyor roller conveyor 1, provide positional limits for the connecting plate 301. Driven by the two belts 202, the connecting plate 301 can replace the traditional two conveyor belts. The friction between the friction contact strip 302 and the belt 202 drives the belt 202 to move, while the elastic support 303 provides elastic support. When the connecting plate 301 passes through the arc section of the belt 202 and the closed-loop slide rail 203, the elastic support 303 can be compressed or stretched to allow the connecting plate 301 to pass smoothly. The radius of the arc section of the belt 202 and the closed-loop slide rail 203 can also be increased to ensure that the connecting plate 301 passes smoothly through the arc section of the belt 202 and the closed-loop slide rail 203.

[0032] The two belts 202 are connected by a drive shaft and driven by a motor and a reducer. Alternatively, a chain can be used instead of belts 202. A toothed block is provided below the connecting plate 301 to engage with the chain and ensure drive. The chain drive needs to be kept clean to avoid affecting the chain when cutting livestock. In terms of conveying capacity, the chain is better than the belts 202. However, belts 202 have better anti-fouling ability, and because the conveying speed is not fast, belts 202 are more suitable for providing transmission for conveying livestock.

[0033] Specifically, a linear motor 6 is fixedly installed on the top of the conveyor roller 1, and an automatic gripper 7 is fixedly installed on the bottom side of the linear motor 6. The moving end of the linear motor 6 can convey the animal carcass in the direction of the automatic gripper 7. After the forelimbs or hindlimbs of the carcass completely abut against the automatic gripper 7, the two grippers of the automatic gripper 7 rotate downward to the horizontal, losing their blocking effect on the carcass.

[0034] The gaps between the conveyor roller 1 and the closed-loop drive device 2 are for the saw blade 4 to cut. When installing the equipment, the position of the saw blade 4 can be adjusted according to the different cutting positions of different animal carcasses. The sufficiently large gap between the conveyor roller 1 and the closed-loop drive device 2 provides convenience for adjusting the position of the saw blade 4.

[0035] Before cutting, the carcass is placed horizontally on the conveyor roller 1. Prior to this, the carcass can be placed horizontally on top of the linear motor 6, which then pushes the carcass towards the automatic gripper 7, inserting the forelimbs or hindlimbs between the two grippers of the automatic gripper 7 until the carcass is completely against the grippers. The two grippers of the automatic gripper 7 then prevent the carcass from moving further. The two grippers of the automatic gripper 7 then rotate horizontally, thus removing the positional restriction on the carcass. In this way, the position where the forelimbs or hindlimbs can no longer move forward is used to determine the position of the forelimb or hindlimb large bone. Since the width of the ribs is known, the position of the joints can be determined. After the clamping and adjusting component 3 clamps the forelimb or hindlimb, it can be used as a position reference to move the forelimb while clamping it. Align the position of three to four ribs near the forelimb with the saw blade 4 to complete the position adjustment of the carcass. In this case, the distance between the automatic gripper 7 and the clamping and adjusting component 3, the position of the large bone joint of the carcass, and the width of the ribs are determined. These can be used as position references to adjust the position of the carcass. Although the accuracy may not be as good as the vision determination method, the accuracy is sufficient and the cost is lower.

[0036] Specifically, lifting and transfer components 5 are respectively installed at the gaps on both sides of the conveyor roller 1 and the closed-loop circulation drive device 2. These components include an electric push rod 501 and a push plate 502 fixedly installed on the top of the electric push rod 501, which can lift the cut fresh meat and slide it outward.

[0037] After being cut by two saw blades 4, the front and rear sections of fresh meat need to be transferred using the lifting and transfer assembly 5. Since the limbs of the front and rear sections are on the clamping and adjusting assembly 3, the part in the gap between the conveyor roller 1 and the closed-loop circulation drive device 2 is larger, has more meat, and is heavier. After the clamping and adjusting assembly 3 conveys the front and rear sections to the top of the push plate 502, the servo motor 305 drives the clamping plate 306 to release the front or rear limbs. The electric push rod 501 lifts the meaty part of the front or rear section upwards and flips the front and rear sections outwards so that they can slide outwards along the guide plate 205. After the conveyor belt is set at the position of the push plate 502, the front and rear sections can be transferred to different workstations.

[0038] It should be noted that if the front and rear sections are conveyed in the same direction, the two lifting and transfer components 5 need to be staggered to match the two parallel conveyor belts. If the front and rear sections are conveyed in opposite directions, they do not need to be staggered. The push plate 502 should be located outside the saw blade 4, corresponding to the position of the front or rear section, to avoid the push plate 502 contacting the middle section.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
