Description

Technical Field

[0001] This utility model relates to the field of meat processing technology, specifically a swing device and a dual-station cutting machine. Background Technology

[0002] Meat cutting machines are widely used in the meat processing industry, such as cutting chicken legs, chicken necks, chicken frames, duck legs, duck necks, steaks, and meat chunks into pieces. Cutting the meat into pieces not only facilitates cooking and processing but also makes packaging easier. Currently, punching machines on the market use a fixed mold that cuts the meat by pressing down on the mold. The material needs to be manually placed into the groove of the mold. Because the groove is located directly below the pressing device, and the pressing mold is constantly driven up and down by a drive mechanism, there is a risk of hand injury during the downward pressing process when placing the product. Therefore, the operation is not safe. Furthermore, the mold only has a single groove, meaning only one product can be placed in at a time. The product must be cut before it can be placed in again, resulting in a long waiting time and low operating efficiency.

[0003] To this end, the applicant designed a multi-functional punching machine (application number 2025202160102). When the device is working, the cylinders on both sides extend and retract synchronously, driving the sliding plate and the movable mold to slide back and forth on the table. This causes the movable mold to move back and forth, positioning the mold groove containing the product directly below the lower die. This moves the original mold groove below the lower die away, facilitating the placement of uncut products. After the movable mold reciprocates and switches positions, the lower die punches and squeezes the product downwards, cutting it with a cutter. This reciprocating motion allows for material feeding during the back-and-forth movement of the movable mold, and also facilitates the placement of the product... The material is further alternatingly stamped and cut, which not only better ensures the continuous and reliable operation of the equipment and helps to improve the cutting efficiency, but also the mold groove is far away from the lower mold when feeding the material, eliminating the risk of hand injury and making it safer and more reliable to use. However, the mold of this type of equipment moves back and forth, requiring workers on both the front and back sides of the equipment, otherwise it is impossible to place the material on the other side of the mold. Moreover, it requires cylinder synchronization to complete the back and forth movement and cutting, which is difficult to achieve and has high requirements for the cylinder. Therefore, the relative cost and subsequent maintenance cost are relatively high. There is an urgent need for a swing device and a dual-station block cutting machine that can be fed by a single person and has more reliable operation. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide a dual-station block cutting machine.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a swinging device, comprising a swinging cam and a swinging arm assembly rotatably disposed on one side of the swinging cam. The axis of the swinging cam is penetrated by a fixed rotating shaft for the rotation of the swinging cam. The surface of the swinging cam near the swinging arm assembly is provided with an inwardly recessed elliptical swinging groove, which is penetrated by the fixed rotating shaft, and the center of the elliptical swinging groove is offset from the center of the swinging cam. The lower end of the swinging arm assembly is provided with a swinging shaft for the swinging arm assembly to swing around. The swinging shaft is located on the side directly below the fixed rotating shaft, so that the swinging shaft and the fixed rotating shaft have a horizontal distance. The swinging arm assembly is close to the surface of the swinging cam. A freely rotatable swinging roller is fixed on the side of the swinging arm assembly near the swinging cam. The swinging roller is located in the elliptical swinging groove, and the rotation of the swinging cam drives the swinging roller to move cyclically along the elliptical swinging groove. A tension spring is fixed on the upper end of the swinging arm assembly away from the swinging shaft, and the tension spring causes the swinging arm assembly to swing elastically away from the swinging shaft.

[0006] Furthermore, the elliptical swing groove has symmetrical swing groove recesses that bend toward the fixed axis on the side near the fixed axis, and the elliptical swing groove between the two swing groove recesses protrudes outward.

[0007] Furthermore, the swing arm assembly consists of a frame structure formed by two bent plate-shaped swing arms connected by connecting columns, and the upper ends of the front and rear plate-shaped swing arms are respectively fixed with an adjustable upper end connection structure through elongated openings and bolts and nuts.

[0008] Furthermore, a coaxial driven gear is fixed on the other side of the swing cam. A driving gear meshes with the bottom of the driven gear on one side. A U-shaped crank arm assembly is fixed on the shaft of the driving gear. The other end of the crank arm assembly is connected to the power output end of the geared motor. The lower end of the pull arm is fitted in the middle part of the crank arm assembly, so that the crank arm assembly drives the pull arm to rotate eccentrically up and down.

[0009] This utility model also relates to a dual-station block cutting machine, including the aforementioned swing device and frame. The rotating shaft of the fixed shaft and the drive gear is rotatably mounted on the gear fixing plate at the bottom of the frame. The swing shaft is located at the bottom between two legs on the same side of one side of the frame. The fixed end of the tension spring is connected to the top of the other leg of the frame. The top of the frame is a horizontal cutting platform. A hollow block cutting knife assembly is set in the center of the cutting platform. A dual-station placement mold that slides left and right is set on the cutting platform. The upper two sides of the swing arm assembly are respectively connected to the bottom front and rear sides of the dual-station placement mold by a rotating shaft through connecting rods. Vertical lifting guide rods are vertically inserted through both ends of the cutting platform. The upper ends of the two lifting guide rods are fixedly connected by a lifting crossbeam. A stamping block with the same shape as the mold groove of the dual-station placement mold is fixed in the middle part of the bottom of the lifting crossbeam. The lower ends of the two lifting guide rods are fixedly connected by a lifting push plate. The upper end of the pull arm is rotatably connected to the center of the lower surface of the lifting push plate by a rotating shaft.

[0010] Furthermore, the opening shape of the cutting blade assembly is the same as that of the mold groove of the dual-station mold, and multiple square-shaped cutting blades with upward-facing blades are provided inside.

[0011] Furthermore, the bottom of the cutting blade assembly is fixed with a receiving groove that extends to the outside of the frame.

[0012] Furthermore, each lifting guide rod vertically passes through the guide sleeves set at both ends of the cutting platform.

[0013] Furthermore, the two molds of the dual-station mold placement are respectively fixed on the sliding plate that slides on the cutting platform. The front and rear edges of the sliding plate are bent downwards and are respectively fixedly connected to the lower surface of the guide slide rail slider at the front and rear bottom of the cutting platform, so that the dual-station mold placement and the sliding plate slide back and forth on the cutting platform along the guide slide rails on each side.

[0014] Furthermore, each side of the frame and the geared motor are covered with protective covers, and the bottom of the frame is supported by multiple freely rotating composite casters.

[0015] With the above configuration, when this utility model is in operation, the product to be cut is placed in the mold slot of the dual-station placement mold away from the stamping block. On one hand, the reduction motor rotates, driving the crank arm assembly to rotate, which in turn drives the pull arm to rotate eccentrically up and down. This continuously drives the lifting push plate, the two lifting guide rods, the lifting beam, and the stamping block to move up and down. When the stamping block moves down to the bottom, it is exactly located in the mold slot of one of the dual-station placement molds. At the same time, the drive gear at the other end of the crank arm assembly drives the driven gear to rotate, which in turn drives the swing cam to rotate. Since the swing roller is located in the elliptical swing groove, and the rotation of the swing cam drives the swing roller to move cyclically along the elliptical swing groove, a tension spring is fixed to the upper end of the swing arm assembly away from the swing axis. The tension spring causes the swing arm to swing. The arm assembly elastically swings away from the swing axis. The swing cam rotates, causing the moving swing roller to move cyclically along the elliptical swing groove. Under the action of the tension spring, the upper end of the swing arm assembly moves back and forth, which in turn drives the sliding plate and the dual-station placement mold to move back and forth on the cutting platform. By controlling the transmission ratio of the drive gear and the driven gear, one mold of the dual-station placement mold can be positioned above the cutting blade assembly while the stamping block moves downward to complete one stamping, cutting the food material in that part into pieces. The other mold of the dual-station placement mold can be used to put in the food material, and when it moves above the cutting blade assembly, it completes the cutting again. This process is repeated to achieve alternating feeding and cutting when the dual-station placement mold moves left and right.

[0016] This invention uses a single geared motor to drive the mold to switch back and forth and to perform upper and lower punching and cutting. It not only has higher synchronization and is easier to control via a program, eliminating the need for a complex control system, but also has a more stable overall structure, better ensuring the continuous and reliable operation of the equipment. This helps to improve cutting and processing efficiency. Moreover, one person can alternately feed material into the two slots of the mold from one side of the machine. When feeding material, the mold groove is far away from the lower pressing mold, eliminating the risk of hand cuts. This makes it safer and more reliable to use, further saving labor costs and bringing greater benefits to users. Attached Figure Description

Detailed Implementation Example 1

[0019] like Figure 5-7 As shown, a swinging device includes a swinging cam 1 and a swinging arm assembly 2 rotatably disposed on one side of the swinging cam 1. The axis of the swinging cam 1 is penetrated by a fixed rotating shaft 3 for rotating the swinging cam 1. The surface of the swinging cam 1 near the swinging arm assembly 2 is provided with an inwardly recessed elliptical swinging groove 4, which is penetrated by the fixed rotating shaft 3, and the center of the elliptical swinging groove 4 is offset from the center of the swinging cam 1. The lower end of the swinging arm assembly 2 is provided with a swinging shaft 5 for swinging the swinging arm assembly 2 around it. The swinging shaft 5 is located on the side directly below the fixed rotating shaft 3, so that the swinging shaft 5 and the fixed rotating shaft 3 are horizontally spaced. The swinging arm assembly 2 is close to the surface of the swinging cam 1. A freely rotatable swinging roller 6 is fixed on the side of the swinging arm assembly 2 near the swinging cam 1. The swinging roller 6 is located in the elliptical swinging groove 4, and the rotation of the swinging cam 1 drives the swinging roller 6 to move cyclically along the elliptical swinging groove 4. A tension spring 7 is fixed on the upper end of the swinging arm assembly 2 away from the swinging shaft 5, and the tension spring 7 causes the swinging arm assembly 2 to swing elastically away from the swinging shaft 5.

[0020] Specifically, the elliptical swing groove 4 is provided with a symmetrical swing groove recess 8 that bends toward the fixed rotating shaft 3 on the side of the elliptical swing groove 4 near the fixed rotating shaft 3, and the elliptical swing groove 4 between the two swing groove recesses 8 protrudes outward.

[0021] The swing arm assembly 2 is composed of a frame structure formed by two bent plate-shaped swing arms connected by connecting columns. The upper ends of the front and rear plate-shaped swing arms are respectively fixed with an adjustable upper end connection structure through a long strip opening and bolts and nuts. A coaxial driven gear 9 is fixed on the other side of the swing cam 1. A driving gear 10 is meshed on the bottom side of the driven gear 9. A U-shaped crank arm assembly 11 is fixed on the rotating shaft of the driving gear 10. The other end of the crank arm assembly 11 is connected to the power output end of the geared motor. The lower end of the pull arm 12 is sleeved in the middle part of the crank arm assembly 11, so that the crank arm assembly 11 drives the pull arm 12 to rotate eccentrically up and down. Example 2

[0022] like Figure 1-7As shown, a dual-station dicing machine includes a swing device and a frame 13 as described in Embodiment 1. The rotating shaft 3 and the drive gear 10 are rotatably mounted on a gear fixing plate 14 at the bottom of the frame 13. The swing shaft 5 is located at the bottom between two legs on the same side of one side of the frame 13. The fixed end of the tension spring 7 is connected to the top of the other leg of the frame 13. The top of the frame 13 is a horizontal cutting platform 15. A hollow dicing blade assembly 16 is provided at the center of the cutting platform 15. A dual-station placement mold 17 that slides left and right is provided on the cutting platform 15. The swing arm... The upper two sides of the assembly 2 are respectively connected to the bottom front and rear sides of the dual-station mold 17 via connecting rods 29 and rotating shafts. Vertical lifting guide rods 18 are vertically inserted through both ends of the cutting platform 15. The upper ends of the two lifting guide rods 18 are fixedly connected via lifting beams 19. A stamping block 20 with the same shape as the mold groove of the dual-station mold 17 is fixed in the middle part of the bottom of the lifting beam 19. The lower ends of the two lifting guide rods 18 are fixedly connected via lifting push plates 21. The upper end of the pull arm 12 is rotatably connected to the center of the lower surface of the lifting push plate 21 via a rotating shaft.

[0023] Specifically: the opening shape of the cutting blade assembly 16 is the same as the mold groove of the dual-station mold 17, and multiple square-shaped cutting blades 22 with their blades facing upwards are provided inside (as disclosed in the prior application 2025202160102: the table surface 4 is provided with a hollow cutting blade opening 5, and a grid-shaped cutting blade 6 is provided inside the cutting blade opening 5). The bottom of the cutting blade assembly 16 is fixed with a receiving groove 23 that extends to the outside of the frame 13. Each lifting guide rod 18 vertically passes through the guide sleeves 24 provided at both ends of the cutting platform 15. The two molds of the dual-station mold 17 are fixed on the sliding plate 25 that slides on the cutting platform 15. The front and rear edges of the sliding plate 25 are bent downward and fixedly connected to the lower surface of the guide rail 26 slider at the front and rear bottom of the cutting platform 15, so that the dual-station mold 17 and the sliding plate 25 slide back and forth on the cutting platform 15 along the guide rail 26 on each side. The sides of the frame 13 and the reduction motor are covered with protective covers 27. The bottom of the frame 13 is also supported by multiple freely rotating composite casters 28.

[0024] This utility model belongs to the same type of equipment as the previously applied multi-functional punching machine (application number 2025202160102), but differs in structure, operation, and cutting stations to adapt to use in small factories and the catering industry. The working principle of this utility model is as follows: During operation, the product to be cut is placed in the mold slot of the dual-station placement mold 17, away from the punching block 20. On one hand, the reduction motor rotates, driving the crank arm assembly 11 to rotate, causing the crank arm assembly 11 to drive the pull arm 12 to rotate eccentrically up and down, thereby continuously driving the lifting push plate 21, the two lifting guide rods 18, the lifting beam 19, and the punching block 20 to move up and down. When the punching block 20 moves downwards to the bottom, it is exactly located in one of the molds of the dual-station placement mold 17. Meanwhile, at the same time, the drive gear 10 at the other end of the crank arm assembly 11 drives the driven gear 9 to rotate, which in turn drives the swing cam 1 to rotate. Since the swing roller 6 is located in the elliptical swing groove 4, and the rotation of the swing cam 1 drives the swing roller 6 to move cyclically along the elliptical swing groove 4, the upper end of the swing arm assembly 2, which is away from the swing shaft 5, is fixed with a tension spring 7. The tension spring 7 causes the swing arm assembly 2 to swing elastically to the side away from the swing shaft 5. That is, the rotation of the swing cam 1 causes the driven swing roller 6 to move cyclically along the elliptical swing groove 4. Under the pulling force of the tension spring 7, the upper end of the swing arm assembly 2 is driven to move back and forth, which in turn drives the sliding plate 25 and the double-station placement mold 17 to move back and forth on the cutting platform 15. Figure 7 As shown, by controlling the transmission ratio of the driving gear 10 and the driven gear 9, one of the molds of the dual-station placement mold 17 can be positioned above the cutting blade assembly 16. At the same time, the stamping block 20 moves downward to complete one stamping, cutting the food material in that part into pieces. The other mold of the dual-station placement mold 17 can hold the food material. When it moves above the cutting blade assembly 16, it completes the cutting again. By repeating this process, the dual-station placement mold 17 can alternately feed and cut materials when moving left and right.

[0025] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
