A sliding groove is formed in the inner base, and a moving pin is slidably connected in the sliding groove. An annular groove is formed on the surface of the moving pin. A connecting rod is rotatably connected to the inner side wall of the sliding groove, and one end of the connecting rod extends into the annular groove and is fixedly connected with a cam.

[0012] The other end of the connecting rod is provided with a third gear and penetrates through the sampling base and extends into the inner groove. A rack that meshes with the third gear is fixedly arranged on the top of the sliding strip.

[0013] Two cutting grooves are formed at the bottom of the moving pin, and the two cutting grooves are symmetrically arranged in the same direction as the conveying direction of the active conveyor belt. Two first trigger controllers are fixedly installed inside the moving pin, and the trigger paddles of the two first trigger controllers respectively extend into the two cutting grooves. A clamping pliers that cooperate with the trigger paddle is rotatably connected in the cutting groove.

[0014] Two brackets are arranged inside the notch, and the brackets are located between the active conveyor belt and the cutting circular saw. Both of the two brackets are inclined, and one of the brackets is fixedly connected to the middle table surface of the strip cutting table, and the other bracket is rotatably connected to the middle table surface of the strip cutting table.

[0015] Passive conveyor belts are rotatably arranged on both of the two brackets. Transmission wheels are arranged on the inner side walls on both sides of the notch, and the transmission wheels frictionally drive and connect the active conveyor belt and the passive conveyor belt on the same side.

[0016] On the inner wall of the notch near the side of the rotating connection bracket, a cylinder electrically connected to the first trigger controller is fixedly arranged, and the telescopic end of the cylinder is connected to the outer shell of the transmission wheel on the same side.

[0020] Preferably, anti-slip teeth are arranged at the bottom end of the clamping pliers.

[0021] Preferably, positioning magnetic blocks matched with each other are fixedly embedded on the opposite sides of the surfaces of the upper pin body and the lower pin body.

[0022] A usage method of an adjustable strip cutting device for beef processing includes the following steps:

[0023] S1. Place the whole beef piece by piece on the active conveyor belt, and use the active conveyor belt to send the beef to the cutting circular saw for strip cutting;

[0024] S2. When the active conveyor belt conveys the beef, the moving beef pushes open the baffle, so that the rotating shaft winds up the torsion spring to drive the first gear to rotate. After the driving slide bar is displaced, the second gear and the cross shaft are used to push the scraper to turn out from the sampling seat. At this time, the top of the beef on the active conveyor belt is cut into meat slices by the popped-up scraper into the sample cavity;

[0025] S3. During the process of the slider moving to drive the scraper to retain a sample, the rack on its surface synchronously pushes the connecting rod and the cam to rotate. The rotating cam pushes the moving pin downward along the annular groove, causing the two clamping pliers to press down on the sample beef slice. As the moving pin continues to move downward, the bottom ends of the two clamping pliers deflect outward, and apply tensile forces in opposite directions to the beef slice. When the beef texture is the same as the tangential direction of the cutting circular saw, the clamping pliers cannot tear the beef slice, and the first trigger controller will not be activated. On the contrary, when the beef texture is different from the tangential direction of the cutting circular saw, the beef slice is torn, the top end of the clamping pliers opens the first trigger controller, and activates the air cylinder to drive the corresponding transmission wheel to perform a reciprocating motion. When the transmission wheel disengages from the contact with the active conveyor belt, it pushes the corresponding passive conveyor belt and the bracket to lift. At this time, the passive conveyor belt is in direct contact with the active conveyor belt for transmission connection, so that the passive conveyor belt performs backward conveying in the opposite direction to the active conveyor belt. Cooperating with another passive conveyor belt that still maintains forward conveying, the two differentially moving passive conveyor belts push the beef on the surface to rotate, enabling the beef to be cut into strips according to the texture direction;

[0026] S4. Before using the clamping pliers to perform texture recognition on the sample beef slice, the operator can rotate the lower pin body to change the two clamping pliers from longitudinal arrangement adapted to the beef conveying direction to horizontal arrangement. At this time, the downward moving clamping pliers apply a horizontal tensile force to the sample beef slice. When the beef texture is the same as the tangential direction of the cutting circular saw, the clamping pliers tear the beef slice and open the second trigger controller, and the two differentially moving passive conveyor belts push the beef on the surface to rotate, enabling the beef to be cut into strips not according to the texture direction.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] In the present invention, the moving beef pushes the baffle, causing the rotating shaft to wind up the torsion spring and drive the first gear to rotate. After driving the slider to displace, the second gear and the cross shaft are used to push the scraper to turn out from the sampling seat. At this time, the top of the beef on the active conveyor belt is cut into slices by the popped-up scraper into the sample cavity. Compared with the traditional strip cutting equipment, the above-mentioned baffle and scraper cooperate to automatically retain a sample of the strip-cut beef during the beef conveying process, which is convenient for the user to quickly trace back using the sample when problems are found in the beef later, facilitating process improvement and raw material control.

[0029] In the present invention, the pressing tongs apply tensile tearing forces in opposite directions to the beef slices. When the beef texture is the same as the tangential direction of the cutting circular saw, the pressing tongs cannot tear the beef slices and will not activate the first trigger controller. On the contrary, when the beef texture is different from the tangential direction of the cutting circular saw, the beef slices are torn, the top of the pressing tongs activates the first trigger controller, and the air cylinder is started to drive the corresponding transmission wheel to perform a reciprocating motion. When the transmission wheel disengages from the contact with the active conveyor belt, it pushes the corresponding passive conveyor belt and the bracket to lift. At this time, the passive conveyor belt is in direct contact with the active conveyor belt for transmission connection, so that the passive conveyor belt performs backward conveying in the opposite direction to the active conveyor belt. Cooperating with another passive conveyor belt that still maintains forward conveying, the two differentially moving passive conveyor belts push the beef on the surface to rotate, enabling the beef to be cut into strips according to the texture direction. Compared with the existing direct cutting into strips, the above-mentioned pressing tongs cooperate with the first trigger controller, which can identify the texture of the sampled beef slices to judge the cutting strip texture of the beef blocks to be cut, and automatically adjust the texture direction of the beef, so that the beef placed on the active conveyor belt can maintain a unified cutting strip effect, and there is no need for manual special control of the placement direction.

[0030] In the present invention, by rotating the lower pin body, the two pressing tongs are converted from the longitudinal direction adapted to the beef conveying direction to the horizontal position. At this time, the lower pressing tongs apply a horizontal tensile tearing force to the sample beef slices. When the beef texture is the same as the tangential direction of the cutting circular saw, the pressing tongs tear the beef slices and activate the second trigger controller. The two differentially moving passive conveyor belts push the beef on the surface to rotate, enabling the beef to be cut into strips not according to the texture direction. In this way, in addition to cutting strips along the texture, the function of cutting strips with different textures is added, and the user can freely choose different cutting strip effects according to the subsequent processing and taste requirements, with better flexibility in use.

Specific embodiments

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] Please refer to Figures 1 to 12, the present invention provides a technical solution: an adjustable strip-cutting device for beef processing, including a strip-cutting table 1, a notch 2 is opened on the left side of the strip-cutting table 1, and a driving conveyor belt 3 is arranged in the notch 2. A cutting circular saw 4 that matches the table top is arranged at the middle position of the strip-cutting table 1. During use, the whole piece of beef is placed on the driving conveyor belt 3 one by one, and the driving conveyor belt 3 is used to send the beef to the cutting circular saw 4 for strip-cutting;

[0046] A sample retainer 5 is arranged on the left side of the strip-cutting table 1, and the sample retainer 5 is located above the driving conveyor belt 3;

[0047] The sample retainer 5 includes a sampling seat 51 fixedly arranged inside the strip-cutting table 1, and the sampling seat 51 is located above the driving conveyor belt 3. A side seat 52 is fixedly connected between the end of the sampling seat 51 and the strip-cutting table 1. A rotating shaft 53 is rotatably connected to the bottom of the side seat 52. A baffle 54 is fixedly connected to the side surface of the rotating shaft 53, and a torsion spring 55 is arranged on the rotating shaft 53. The two ends of the torsion spring 55 are respectively connected to the rotating shaft 53 and the side seat 52;

[0048] An inner groove 56 is opened inside the side seat 52, and the inner groove 56 extends into the sampling seat 51. A slide bar 57 is slidably connected in the inner groove 56, and a first tooth surface 58 is opened on the side surface of the slide bar 57. The rotating shaft 53 extends into the inner groove 56, and the top end of the rotating shaft 53 is provided with a first gear 59 that meshes with the first tooth surface 58. When the driving conveyor belt 3 conveys beef, the moving beef pushes open the baffle 54, so that the rotating shaft 53 winds up the torsion spring 55 to drive the first gear 59 to rotate, and drives the slide bar 57 to displace;

[0049] A sample cavity 510 is opened inside the sampling seat 51, and the upper and lower ends of the sample cavity 510 penetrate through the sampling seat 51. A scraping knife 511 is arranged inside the sample cavity 510, and cross shafts 512 are fixedly arranged at both ends of the scraping knife 511. The scraping knife 511 is rotatably connected in the sample cavity 510 through the cross shafts 512, and the cross shafts 512 penetrate into the inner groove 56. The penetrating end of the cross shaft 512 is provided with a second gear 513. A second tooth surface 514 that meshes with the second gear 513 is opened on the top of the slide bar 57. When the slide bar 57 displaces, the scraping knife 511 is pushed out of the sampling seat 51 by the second gear 513 and the cross shaft 512. At this time, a piece of meat is cut out from the top of the beef on the driving conveyor belt 3 into the sample cavity 510 by the popped-up scraping knife 511;

[0050] A reversing assembly 515 for adjusting the texture direction of the beef is arranged on the sampling seat 51, the strip-cutting table 1 and the driving conveyor belt 3.

[0051] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 12As shown, the commutation assembly 515 includes an inner seat 5151 fixedly arranged in the middle of the sample chamber 510. A chute 5152 is formed in the inner seat 5151. A moving pin 5153 is slidably connected in the chute 5152. An annular groove 5154 is formed on the surface of the moving pin 5153. A connecting rod 5155 is rotatably connected to the inner side wall of the chute 5152. One end of the connecting rod 5155 extends into the annular groove 5154 and is fixedly connected to a cam 5156.

[0052] The other end of the connecting rod 5155 is provided with a third gear 5157 and penetrates through the sampling seat 51 to extend into the inner groove 56. A rack 5158 meshing with the third gear 5157 is fixedly arranged on the top of the slide bar 57. During the movement of the slide bar 57, the rack 5158 on its surface synchronously pushes the connecting rod 5155 and the cam 5156 to rotate. The rotating cam 5156 pushes the moving pin 5153 downward along the annular groove 5154.

[0053] Two cutting grooves 5159 are formed at the bottom of the moving pin 5153. The two cutting grooves 5159 are symmetrically arranged in the same direction as the conveying direction of the active conveyor belt 3. Two first trigger controllers 51510 are fixedly installed inside the moving pin 5153. The trigger paddles of the two first trigger controllers 51510 respectively extend into the two cutting grooves 5159. A clamping pliers 51511 matched with the trigger paddle is rotatably connected in the cutting groove 5159. When the moving pin 5153 moves downward, the two clamping pliers 51511 press downward on the sample beef slice. As the moving pin 5153 continues to move downward, the bottom ends of the two clamping pliers 51511 deflect outward and apply a tearing force in the opposite direction to the beef slice. When the beef texture is the same as the tangential direction of the cutting circular saw 4, the clamping pliers 51511 cannot tear the beef slice and will not open the first trigger controller 51510. On the contrary, when the beef texture is different from the tangential direction of the cutting circular saw 4, the beef slice is torn, and the top end of the clamping pliers 51511 opens the first trigger controller 51510.

[0054] Two brackets 51512 are arranged in the notch 2. The brackets 51512 are located between the active conveyor belt 3 and the cutting circular saw 4. The two brackets 51512 are both inclined. One of the brackets 51512 is fixedly connected to the middle tabletop of the cutting strip table 1, and the other bracket 51512 is rotatably connected to the middle tabletop of the cutting strip table 1.

[0055] Passive conveyor belts 51513 are rotatably arranged on the two brackets 51512. Driving wheels 51514 are arranged on the inner side walls on both sides of the notch 2. The driving wheels 51514 are frictionally drivingly connected to the active conveyor belt 3 and the passive conveyor belt 51513 on the same side. At this time, the passive conveyor belt 51513 conveys in the same direction as the active conveyor belt 3.

[0056] On the inner wall of the notch 2 close to one side of the rotating connection bracket 51512, a cylinder 51515 electrically connected to the first trigger controller 51510 is fixedly arranged, and the telescopic end of the cylinder 51515 is connected to the outer shell of the transmission wheel 51514 on the same side. The first trigger controller 51510 can start the cylinder 51515 to drive the corresponding transmission wheel 51514 to perform a reciprocating motion. When the transmission wheel 51514 disengages from the contact with the active conveyor belt 3, it pushes the corresponding passive conveyor belt 51513 and the bracket 51512 to lift. At this time, the passive conveyor belt 51513 is in direct contact with the active conveyor belt 3 for transmission connection, so that the passive conveyor belt 51513 performs backward conveying in the opposite direction to the active conveyor belt 3.

[0057] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 12 shown, the moving pin 5153 is composed of an upper pin body 51531 and a lower pin body 51532, and the upper pin body 51531 and the lower pin body 51532 are rotatably connected. An adjustment assembly 51516 cooperating with the pressing tongs 51511 is arranged on the upper pin body 51531 and the lower pin body 51532.

[0058] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 12 shown, the adjustment assembly 51516 includes a mounting groove 515161 opened at the bottom of the upper pin body 51531. Two first trigger controllers 51510 are fixedly arranged in the mounting groove 515161, and two second trigger controllers 515162 electrically connected to the cylinder 51515 are fixedly arranged in the mounting groove 515161. A circular groove 515163 is opened at the top of the lower pin body 51532, and the circular groove 515163 communicates with two cutting grooves 5159. The trigger levers of the first trigger controller 51510 and the second trigger controller 515162 both extend into the circular groove 515163. Rotate the lower pin body 51532 to change the two pressing tongs 51511 from being longitudinally adapted to the beef conveying direction to being horizontally placed. At this time, moving the pressing tongs 51511 downward applies a horizontal tearing force to the sample beef slices. When the beef texture is the same as the tangential direction of the cutting circular saw 4, the pressing tongs 51511 tear the beef slices, turn on the second trigger controller 515162, and correspondingly control the cylinder 51515.

[0059] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 12As shown, a limiting block for restricting the clamping pliers 51511 to be inclined is fixedly arranged inside the grooving 5159. The limiting block can constrain the clamping pliers 51511 in the non-pressed state to a preset inclined state, ensuring that the clamping pliers 51511 can move outward along the surface of the beef after moving downward.

[0060] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 12 As shown, anti-slip teeth are arranged at the bottom end of the clamping pliers 51511. When the clamping pliers 51511 move downward, the anti-slip teeth are used to contact the beef, which can prevent the clamping pliers 51511 from slipping along the surface of the beef and ensure the stability of the force exerted by the clamping pliers 51511 on the beef.

[0061] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 12 As shown, positioning magnets are fixedly embedded on the opposite sides of the surfaces of the upper pin body 51531 and the lower pin body 51532. Through the magnetic force traction between the positioning magnets on both sides, the rotation of the upper pin body 51531 can be assisted to accurately align with the lower pin body 51532, ensuring that the positions adjusted by the first trigger controller 51510 and the second trigger controller 515162 are adapted to the clamping pliers 51511.

[0062] A usage method of an adjustable beef slicing device includes the following steps:

[0063] S1. Place the whole beef piece by piece on the active conveyor belt 3, and use the active conveyor belt 3 to send the beef to the cutting circular saw 4 for slicing.

[0064] S2. When the active conveyor belt 3 conveys the beef, the moving beef pushes open the baffle 54, so that the rotating shaft 53 winds up the torsion spring 55 to drive the first gear 59 to rotate. After the driving slide bar 57 is displaced, the second gear 513 and the cross shaft 512 are used to push the scraper 511 to turn out from the sampling seat 51. At this time, the top of the beef on the active conveyor belt 3 is cut into slices by the popped-up scraper 511 and sent into the sample chamber 510.

[0065] S3. During the process of the slider 57 moving to drive the scraper 511 to take a sample, the rack 5158 on its surface synchronously pushes the connecting rod 5155 and the cam 5156 to rotate. The rotating cam 5156 pushes the moving pin 5153 downward along the annular groove 5154, causing the two clamping pliers 51511 to press down on the sample beef slice. As the moving pin 5153 continues to move downward, the bottom ends of the two clamping pliers 51511 deflect outward and apply tearing forces in opposite directions to the beef slice. When the beef texture is the same as the tangential direction of the cutting circular saw 4, the clamping pliers 51511 cannot tear the beef slice and will not open the first trigger controller 51510. On the contrary, when the beef texture is different from the tangential direction of the cutting circular saw 4, the beef slice is torn, the top end of the clamping pliers 51511 opens the first trigger controller 51510, and the air cylinder 51515 is started to drive the corresponding transmission wheel 51514 to perform a reciprocating motion. When the transmission wheel 51514 disengages from the contact with the active conveyor belt 3, it pushes the corresponding passive conveyor belt 51513 and the bracket 51512 to lift. At this time, the passive conveyor belt 51513 is in direct contact with the active conveyor belt 3 for transmission connection, so that the passive conveyor belt 51513 performs backward conveying in the opposite direction to the active conveyor belt 3. Cooperating with another passive conveyor belt 51513 that still maintains forward conveying, the two differentially moving passive conveyor belts 51513 push the beef on their surfaces to rotate, enabling the beef to be cut into strips according to the texture direction.

[0066] S4. Before using the clamping pliers 51511 to perform texture recognition on the sample beef slice, the operator can rotate the lower pin body 51532 to convert the two clamping pliers 51511 from the longitudinal direction adapted to the beef conveying direction to the horizontal position. At this time, when the clamping pliers 51511 are moved downward, a horizontal tearing force is applied to the sample beef slice. When the beef texture is the same as the tangential direction of the cutting circular saw 4, the clamping pliers 51511 tear the beef slice and open the second trigger controller 515162. The two differentially moving passive conveyor belts 51513 push the beef on their surfaces to rotate, enabling the beef to be cut into strips not according to the texture direction.

[0067] The above shows and describes the basic principles, main features and advantages of the present invention.

6. The adjustable beef strip cutting device according to claim 5, characterized in that: The upper pin body and the lower pin body have matching positioning magnetic blocks fixedly embedded on opposite sides of the surface.

7. The method for using the adjustable beef strip cutting device according to claim 6 comprises the following steps: S1. Place the whole pieces of beef one by one on the active conveyor belt, and use the active conveyor belt to send the beef to the cutting circular saw for cutting; S2. When the active conveyor belt is conveying beef, the moving beef pushes the baffle plate, so that the rotating shaft winding torsion spring drives the first gear to rotate. After the driving slider is displaced, the scraper is pushed out of the sampling seat by the second gear and the horizontal axis. At this time, the top of the beef on the active conveyor belt is ejected by the scraper to cut the meat slices into the sample chamber; S3. When the beef needs to be cut into strips in the direction of the grain: while the slider moves to drive the scraper to retain the sample, the rack on its surface synchronously pushes the connecting rod and the cam to rotate, and the rotating cam pushes the moving pin down along the annular groove, so that the two pressing clamps press down on the sample beef slice. As the moving pin continues to move downward, the bottom ends of the two pressing clamps deflect outward and apply tearing forces in opposite directions to the beef slice. When the beef grain is in the same direction as the cutting circular saw, the pressing clamps cannot tear the beef slice and the first trigger controller will not be opened. On the contrary, when the beef grain is in a different direction from the cutting circular saw, the beef slice When the beef is torn apart, the top of the pressing pliers opens the first trigger controller and starts the cylinder to drive the corresponding transmission wheel to perform a reciprocating motion. When the transmission wheel is out of contact with the active conveyor belt, it pushes the corresponding passive conveyor belt and the bracket to lift up. At this time, the passive conveyor belt is directly in contact with the active conveyor belt for transmission connection, so that the passive conveyor belt is transported backward in the opposite direction of the active conveyor belt, and cooperates with the other passive conveyor belt that is still transporting forward. The two passive conveyor belts that move in different directions push the beef on the surface to rotate, so that the beef can be cut into strips according to the grain direction. The beef needs to be cut into strips other than in the direction of the grain: before using the pressing jaws to identify the texture of the sample beef slices, the operator rotates the lower pin body to convert the two pressing jaws from a longitudinal position to a horizontal position that matches the beef conveying direction. At this time, the lower pressing jaws apply a horizontal tearing force to the sample beef slices. When the beef texture is in the same direction as the cutting circular saw, the pressing jaws tear the beef slices apart, turn on the second trigger controller, and the two passive conveyor belts moving in the differential direction push the beef on the surface to rotate, so that the beef can be cut into strips other than in the direction of the grain.
