DETAILED DESCRIPTION
[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0024] Referring to Figure 1 The meat surface finishing device of the present application is provided with a separating tool 1. It should be noted that in the present embodiment, the separating tool 1 is more suitable for meat with a relatively flat surface and separating surface fat, and more specifically, it is suitable for the step of separating fat from pork after the pork is separated into pieces. Specifically, the separating tool 1 is provided with a blade 101 and a driving structure 2 for driving the blade 101 to rotate and press down. During the process of rotating and pressing down of the blade 101, the blunt side of the blade 101 approaches the fat layer 301 in an arc trajectory and gradually presses the fat layer 301 to approach the muscle layer 302. The driving structure 2 is provided with an in-place sensing device 4. After the blade 101 approaches the muscle layer 302 and gradually presses on the muscle layer 302, it is affected by the reaction force. When a certain pressure is reached, the in-place sensing device 4 can be triggered to stop the movement of the driving structure 2, so that the blade 101 can be pressed on the muscle layer 302. In this way, the fat layer 301 and the muscle layer 302 can be separated more thoroughly during the subsequent transverse movement of the blade 101 relative to the meat product or the movement of the meat product relative to the blade 101.
[0025] Referring to Figures 2-5As shown, in the present embodiment, the blade 101 has a blade body, the edge of the blade body has a first cutting edge 101a, the first cutting edge 101a is a single-sided blade, the effect of the single-sided blade is that it can only be used in one direction, and it has a dull back, during the process of the blade 101 rotating and pressing down, the back of the first cutting edge 101a first contacts the fat layer 301 (as shown in Figure 3 ), the back of the first cutting edge 101a is dull, so it only has a pressing effect and does not cut the fat layer 301, and because fat is a soft granular substance and muscle is a hard strip-like substance, during pressing, the fat is separated so that the back of the first cutting edge 101a can approach the muscle layer 302 (as shown in Figure 4 ), and when it contacts the muscle layer 302, it is resisted, thereby feeding back to the position sensing device 4 (as shown in Figure 5 ), so that the blade 101 can stop in time; during the subsequent separation process of the blade 101, the blade 101 uses a beveling method to more completely separate the fat layer 301 of the meat product.
[0026] Referring to Figures 1-3As shown, in the embodiment, the driving structure 2 comprises two reduction motors 201, each of which is provided with a driving arm 202, and the front end of each of the two driving arms 202 is hingedly connected with a cutter seat 203, the cutter 101 is mounted at both ends of the cutter seat 203, the cutter seat 203 is centered at the hinge point, the front end is a bayonet part for mounting the cutter 101, the cutter 101 is mounted on the cutter seat 203 through the bayonet part, and the rear end is an extension handle 2031, a spring fixing rod 2032 is arranged on the extension handle 2031, the spring fixing rod 2032 is inserted on the driving arm 202 and the upper half is above the driving arm 202, the spring fixing rod 2032 is used for mounting the in-place sensing device 4, the in-place sensing device 4 comprises a spring 401 and a proximity switch 402, a hemispherical head 403 is sleeved on the spring fixing rod 2032, and a gasket 404 is sleeved on the upper half of the spring fixing rod 2032, the spherical surface of the hemispherical head 403 is in contact with the upper surface of the driving arm 202, the spring 401 is sleeved on the upper half of the spring fixing rod 2032 and is between the hemispherical head 403 and the gasket 404, a nut 405 is arranged on the top of the spring fixing rod 2032 for fixing the gasket 404, the spring 401 and the hemispherical head 403, an outer lug 4041 is arranged on the periphery of the gasket 404, and the proximity switch 402 is arranged on the outer lug 4041; in operation, the driving arm 202 is driven by the reduction motor 201 to rotate downward, thereby driving the cutter 101 to rotate and press downward, in the process of rotating and pressing downward of the cutter 101, the cutter 101 first approaches the fat layer 301 and gradually presses the fat layer 301 to approach the muscle layer 302, after reaching the muscle layer 302, the extension handle 2031 at the rear end of the cutter seat 203 is raised relative to the driving arm 202 due to the influence of the reaction force, the spring 401 is compressed, the extension handle 2031 gradually approaches the driving arm 202, and the driving arm 202 stops after the proximity switch 402 is triggered.
[0027] In an embodiment, the application is provided with a conveying device arranged below the separating tool 1, which is used to carry the meat product and drive the meat product to move towards the separating tool 1 to complete the separation.
[0028] As other embodiments, the application can adopt a linear sliding table or other linear driving device 5 to drive the separating tool 1 to move towards the meat product to separate the fat layer 301; however, the conveying device not only enables the meat product to move towards the separating tool 1 to achieve separation, but also can be linked with the separating tool 1 to complete the automatic production process, and therefore the conveying device is preferred.
[0029] Specifically, the conveying device of the present application can adopt a roller conveyor 6 or a belt conveyor for conveying, and the conveying device is coupled with the in-place sensor, in operation, when the meat product reaches below the separating tool 1, it can be sensed by the in-place sensor, so as to feed back a signal to the conveying device to stop, and after the blade 101 of the separating tool 1 is pressed down, the meat product is driven to continue advancing.
[0030] Referring to Figure 1 , Figure 2 In the most preferred embodiment, the fat-removing device of the present application can be provided with both a conveying device and a linear driving device 5 to drive the separating tool 1, and both are coupled with the in-place sensor, in operation, when the meat product reaches below the separating tool 1, it can be sensed by the in-place sensor, the conveying device stops, the linear driving device 5 drives the separating tool 1 to move towards the meat product after the blade 101 of the separating tool 1 is pressed down, and the conveying device also drives the meat product to move towards the separating tool 1, so that the speed of the blade 101 is faster, the separating effect is better, and the efficiency is improved.
[0031] Referring to Figure 2 , Figure 3 In one embodiment, the conveying device preferably adopts a roller conveyor 6, which has a conveying surface composed of a plurality of rollers, and a pressure-type in-place sensor 7 is installed in the gap between the rollers, the pressure-type in-place sensor 7 has a contact part 701 protruding from the conveying surface of the roller conveyor 6, the contact part 701 has a stop inclined surface, in operation, the meat product advances with the conveying device, and after hitting the stop inclined surface, the contact part 701 is pressed down to trigger the pressure-type in-place sensor 7; the main advantage of this embodiment is that the meat product has a certain resistance, which can eliminate the inertia of the meat product and avoid the meat product from not stopping in place, thereby affecting the subsequent separating effect.
[0032] In one embodiment, the blade 101 stops at a first depth 3a slightly below the interface between the fat layer 301 and the muscle layer 302 when approaching the front edge of the meat product, stopping at the front edge position can make the fat layer 301 separate more thoroughly in the horizontal plane, and stopping at the first depth 3a can make the fat layer 301 separate more thoroughly in the vertical plane, simply speaking, if it does not reach the front edge position, some fat will remain at the position close to the front edge (such as Figure 5If the first depth 3a is not reached, a thin layer of fat will remain on the entire or partial surface of the meat product. It should be noted that the blade 101 is rotated and pressed down and feedback is provided by the in-position sensing device 4, so that the blade 101 can be accurately stopped at the first depth 3a. This is because the boundary between the fat layer 301 and the muscle layer 302 is not a horizontal plane. When the blade 101 is rotated and pressed down to approach the muscle layer 302, the blade 101 will not immediately be subjected to resistance. This is because the muscle is soft. The blade 101 will be pressed against the muscle layer 302 and will then be subjected to resistance, which will be fed back to the in-position sensing device 4. Thus, the subsequent separation process can be clean.
[0033] It should be noted that the blade 101 stopping at the front edge position can only be a relatively ideal state. This is because the fat layer 301 is slippery. When the blade 101 reaches the front edge position, the fat layer 301 can slide away. This will cause the blade 101 to be transversely arranged in front of the meat product. The blade 101 will naturally be unable to perform further cutting. If subsequent actions are forcibly performed, the meat product will not be moved. Therefore, in another embodiment, as shown in Figure 5 the blade 101 is stopped at a second position 3b, which is close to the front edge position of the meat product. In the case where the blade 101 is stopped at the second position 3b, in order to ensure that the separation in the transverse layer is relatively complete and that fat is not left on the edge of the meat product, a second separation tool can be arranged behind the separation tool 1 and a turning device can be arranged on the roller conveyor 6 to turn the direction of the meat product. Thus, the remaining fat can be separated again and the separation in the vertical layer can be more complete. In addition to this embodiment, as shown in Figure 7 , Figure 8 a curved blade can be arranged on the back of the blade body. The curved blade has a curved blade body and a second blade edge 101b. The orientation of the second blade edge 101b is opposite to that of the first blade edge 101a. That is, the second blade edge 101b is arranged upward. After the blade 101 is rotated and pressed down to the position, the second blade edge 101b faces the front edge of the meat product. The separation tool 1 is integrally arranged on a device that provides linear motion to drive the blade 101 to move in the direction of the front edge when the first depth 3a and the second edge position are reached. Thus, the fat at the front edge is separated. Then, the blade 101 is moved back to separate the remaining fat by using the single-sided blade. This embodiment can simplify the structure of the device, reduce the cost, and improve the efficiency. Therefore, this embodiment is preferred.
[0034] In one embodiment, the present application is provided with a visual imaging system, which can be matched with the separating tool 1 to make more accurate trimming of the surface fascia of meat products. The specific process is similar to separating fat. For meat products with fascia, such as beef brisket; when separating the surface fascia of beef brisket, the in-place sensing device 4 of the separating tool 1 needs to adjust the setting value of the pressure feedback. After the blade 101 is pressed, it is slightly blocked, the linear drive device 5 drives the separating tool 1 to separate, and the driving structure 102 adjusts according to the pressure feedback during the separation process, so that the blade 101 is always pressed on the surface of the meat product, thereby being able to adapt to some uneven surfaces and trim the fascia cleanly.
