Description

Technical Field

[0001] This invention relates to the field of meat processing technology, specifically to an automatic conveying device for beef cutting. Background Technology

[0002] With the continuous development of the meat processing industry, beef processing has gradually shifted from traditional manual operation to automated and continuous equipment. Especially in large-scale processing scenarios, beef is usually continuously transported to the cutting area by a conveyor device and then cut by a cutting blade, thereby improving processing efficiency and reducing labor costs.

[0003] However, existing automatic beef cutting and conveying devices often lack adaptability when dealing with beef of varying thicknesses in actual use. On the one hand, variations in material thickness can lead to unstable pressing conditions, resulting in either insufficient or excessive pressing, which affects the stability of the material during the cutting process. On the other hand, the operating speed of the cutting mechanism is usually kept constant, making it difficult to adjust to changes in material thickness. When cutting thicker or thinner materials, uneven cutting and rough cut surfaces can easily occur, thus affecting the final processing quality. Summary of the Invention

A pressing mechanism is arranged on an upper support above the cutting mechanism. The pressing mechanism includes a pressing plate that can be reciprocated vertically and an elastic element for applying downward elastic pressure to the pressing plate. During the material conveying process, the pressing plate can adaptively adjust its height position according to the material thickness under the action of the elastic element to press the material during the conveying process. The speed regulating mechanism is connected to the clamping mechanism and the cutting mechanism respectively. The speed regulating mechanism is used to adjust and control the cutting speed of the cutting mechanism synchronously according to the material thickness when the clamping mechanism makes adaptive height adjustments according to the material thickness.

[0009] As a preferred embodiment of the present invention, the elastic element is a spring, one end of which abuts against the pressure plate and the other end of which abuts against the upper bracket. The spring is used to provide a continuous downward pressing force to the pressure plate.

[0010] As a preferred embodiment of the present invention, the speed regulating mechanism includes: The first gear is fixed to a rotating shaft on one side of the cutting blade, and a second gear meshes below the first gear; A variable diameter pulley is provided, the output end of which is fixedly connected to a second gear, and the input end of which is fixedly connected to the output shaft of a second motor mounted on a lower bracket. The variable diameter pulley is used to change the transmission speed transmitted to the second gear.

[0011] As a preferred embodiment of the present invention, the variable diameter pulley includes: The first conical wheel has its output shaft side fixedly connected to the second gear. The second conical wheel has its input shaft fixed to the second motor. A transmission belt connects the first and second conical wheels. The speed can be adjusted by changing the mating diameter of the transmission belt between the first and second conical wheels.

[0012] As a preferred embodiment of the present invention, the speed regulating mechanism further includes: A rotating ring, which is rotatably sleeved on a second conical wheel; A lever, one end of which is rotatably connected to a lower support, and a connecting rod connecting the lever and a rotating ring, one end of which is rotatably connected to the rotating ring and the other end of which is rotatably connected to one end of the lever, and a sliding groove is provided at the free end of the lever.

[0013] As a preferred embodiment of the present invention, a sliding roller is slidably disposed in the sliding groove, and the sliding roller is fixedly connected to a drive rod installed on one side of the pressure plate.

[0014] As a preferred embodiment of the present invention, the driving source is a first motor, which is used to provide constant conveying power to the two conveyor belts.

[0018] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-13 The present invention discloses an automatic beef cutting and conveying device, including a lower support 1, a cutting mechanism, a pressing mechanism and a speed regulating mechanism.

[0020] The lower support 1 is provided with two conveyor belts 2 and a drive source for driving the two conveyor belts 2 at a constant speed. The upper support 27 is fixedly connected to the lower support 1.

[0021] The cutting mechanism is arranged on the conveying path of the conveyor belt 2. The cutting mechanism includes a cutting blade 4, which is set at the gap between the two conveyor belts 2 and is used to cut the conveyed material.

[0022] The clamping mechanism is arranged on the upper support 27 above the cutting mechanism. The clamping mechanism includes a clamping plate 18 that can be reciprocated in the vertical direction and an elastic element for applying downward elastic pressure to the clamping plate 18. During the material conveying process, the clamping plate 18 can adaptively adjust its height position according to the material thickness under the action of the elastic element in order to hold the material during the conveying process.

[0023] The speed regulating mechanism is connected to the clamping mechanism and the cutting mechanism respectively. The speed regulating mechanism is used to adjust and control the cutting speed of the cutting mechanism synchronously according to the material thickness when the clamping mechanism makes adaptive height adjustments according to the material thickness.

[0024] In this embodiment, the lower support 1 serves as the installation foundation for the entire device, providing support for the conveyor belt 2, drive source, and upper support 27. This ensures that all components can be stably assembled and work together, effectively preventing problems such as shaking and displacement due to unstable foundations during long-term operation, and ensuring the overall reliability of operation. The two conveyor belts 2 are arranged in parallel on the lower support 1, and are driven by the drive source to achieve synchronous and constant speed operation. This allows them to smoothly carry the beef material to be cut, maintaining a uniform and stable movement during the conveying process. This avoids uneven material conveying speed leading to deviations in the cutting position, and also provides a stable guarantee for the continuous operation of subsequent cutting operations, meeting the needs of continuous conveying in large-scale meat processing.

[0025] The upper bracket 27 is fixed above the lower bracket 1, and its position is compatible with the cutting mechanism and the clamping mechanism. It provides a solid mounting carrier for the clamping mechanism, ensuring that the clamping mechanism can accurately correspond to the upper position of the cutting mechanism. This ensures the coordinated operation of the clamping and cutting actions and avoids the clamping position shift due to unstable installation foundation, which would affect the cutting effect. The cutting mechanism is arranged on the conveying path of the conveyor belt 2, and the cutting blade 4 is precisely set in the gap between the two conveyor belts 2. This allows the material to be cut by the cutting blade 4 without additional transfer or positioning when it is uniformly conveyed to the cutting area by the conveyor belt 2. This effectively reduces the material transfer links, improves the overall processing efficiency, and avoids problems such as material damage and position shift during transfer. It also improves the shortcomings of low cutting efficiency and high material loss of the existing device.

[0026] The clamping mechanism is installed on the upper bracket 27 and positioned above the cutting mechanism. The clamping plate 18 can reciprocate in the vertical direction. The elastic element continuously applies downward elastic pressure to the clamping plate 18, so that when the material is conveyed to the cutting area, the clamping plate 18 can adaptively adjust its height according to the actual thickness of the material, always maintaining stable pressure on the material. This effectively avoids the material jumping and offset problems caused by the inability of the existing device's clamping mechanism to adaptively adjust, ensuring the stability of the cutting process.

[0027] The speed control mechanism is connected to both the pressing mechanism and the cutting mechanism, and can respond in real time to the height adjustment of the pressing mechanism. When the pressing plate 18 moves up and down with the change of material thickness, the cutting speed of the cutting mechanism is adjusted synchronously to match the material thickness. This solves the problems of incomplete cutting of thick meat and damage to thin meat caused by the fixed cutting speed of existing devices, improves cutting accuracy and meat quality, and also extends the service life of the cutting blade 4. This ensures that the device can adapt to the cutting needs of beef of different thicknesses, further improves the practicality and adaptability of the device, and meets the higher requirements of large-scale meat processing for cutting quality and efficiency.

[0028] Please see Figures 1-13 As a preferred technical solution of the present invention, a rotating shaft 5 is fixedly connected to the center of the cutting blade 4, and the rotating shaft 5 is rotatably mounted on the lower bracket 1 through a bearing.

[0029] In this embodiment, fixing the rotating shaft 5 to the center of the cutting blade 4 ensures that the cutting blade 4 is subjected to uniform force during rotation, avoids cutting deviation caused by eccentric rotation, ensures the stability of the cutting trajectory, thereby improving the flatness of the cutting surface and reducing meat loss caused by cutting deviation.

[0030] The rotating shaft 5 is rotatably mounted on the lower bracket 1 via bearings. The bearings effectively reduce the frictional resistance of the rotating shaft 5 during rotation, making the rotation of the cutting blade 4 smoother and more stable, avoiding jamming or shaking, and ensuring the continuity of the cutting process. This installation method provides stable support for the cutting blade 4 and ensures that the cutting blade 4 rotates flexibly under power, adapting to materials conveyed at a constant speed. It keeps the cutting action synchronized with the material conveying rhythm, effectively solving the problems of insufficient cutting accuracy and meat damage caused by unstable installation and uneven rotation of the cutting blade 4 in existing devices. This further improves the stability and reliability of the segmentation operation, meeting the actual needs of meat processing for cutting quality and efficiency. It also provides a stable structural basis for subsequent adjustment of the cutting rate, ensuring that the cutting blade 4 can maintain a stable rotation state during the cutting of beef of different thicknesses, ensuring consistent cutting results.

[0031] Please see Figures 1-11 As a preferred technical solution of the present invention, the pressing mechanism further includes an inlet plate 23. Two inlet plates 23 are provided and are symmetrically fixed to both ends of the pressing plate 18 along the material conveying direction. Multiple abutment rollers 24 for guiding the material to smoothly enter the pressing plate 18 are rotatably installed on the side of the inlet plate 23 facing the conveyor belt 2. A cutting groove 19 for avoiding the cutting blade 4 is opened at the center of the pressing plate 18 in accordance with the cutting path of the cutting blade 4.

[0032] The clamping mechanism also includes guide rods 20, guide blocks 22, and mounting brackets 25. There are two guide rods 20, which are symmetrically fixed to the clamping plate 18. Elastic elements are sleeved on the guide rods 20. The guide blocks 22 are slidably sleeved on the guide rods 20 and can be detachably fixedly mounted on the upper bracket 27. Multiple mounting brackets 25 are installed at equal intervals on the lower side of the clamping plate 18. Multiple sliding wheels 26 are rotatably mounted at equal intervals on the mounting brackets 25 to reduce the frictional resistance between the material and the clamping plate 18.

[0033] Preferably, the elastic element is a spring 21, one end of which abuts against the pressure plate 18 and the other end against the upper bracket 27. The spring 21 is used to provide a continuous downward pressing force to the pressure plate 18.

[0034] In this embodiment, two inlet plates 23 are symmetrically fixed to both ends of the pressing plate 18 along the material conveying direction. Multiple abutment rollers 24, which are equidistantly mounted on the side facing the conveyor belt 2, can guide the material when it enters the pressing area, reduce the impact and obstruction when the material enters, avoid the material from getting stuck or deviating, and ensure that the material can enter the pressing plate 18 smoothly and steadily, laying the foundation for subsequent stable pressing and cutting operations. This effectively improves the problem of unsmooth material entry in the existing device.

[0035] The cutting groove 19 at the center of the pressure plate 18, which is aligned with the cutting path of the cutting blade 4, effectively avoids the cutting blade 4, preventing structural interference between the cutting blade 4 and the pressure plate 18 during the cutting process. This ensures continuous and smooth cutting operations and prevents damage to the meat or a decrease in cutting accuracy due to interference, further improving cutting quality. Two guide rods 20 are symmetrically fixed to the pressure plate 18. One end of the elastic element (spring 21) on the guide rod 20 abuts against the pressure plate 18, and the other end abuts against the upper bracket 27. This provides a continuous downward pressing force to the pressure plate 18, ensuring that the pressure plate 18 maintains stable pressing on the material even when it can adaptively adjust according to the material thickness. This adapts to beef materials of different thicknesses and solves the defects of existing devices where the pressing mechanism cannot adaptively adjust and the pressing is unstable.

[0036] The guide block 22 is slidably sleeved on the guide rod 20 and detachably fixedly installed on the upper bracket 27. It provides stable guidance and limit for the up and down sliding of the guide rod 20, preventing the pressing plate 18 from tilting or shifting during its up and down movement, ensuring the accuracy of the pressing position, and facilitating the installation, maintenance and repair of the device. The multiple mounting brackets 25 installed at equal intervals on the lower side of the pressing plate 18 can effectively reduce the frictional resistance between the material and the pressing plate 18, so that the material can still be smoothly conveyed with the conveyor belt 2 under the stable pressing state, avoiding material damage or conveying jams caused by excessive friction. It improves the problem of high material conveying resistance and easy jamming in the existing device, further improving the overall operational stability and processing efficiency of the device, ensuring that the device can adapt to the continuous operation requirements of large-scale beef cutting, and improving the cutting quality and production efficiency.

[0037] Please see Figures 1-7 As a preferred technical solution of the present invention, the speed regulating mechanism includes a first gear 6 and a variable diameter pulley. The first gear 6 is fixedly connected to the rotating shaft 5 on one side of the cutting blade 4. A second gear 7 is meshed below the first gear 6. The output end of the variable diameter pulley is fixedly connected to the second gear 7. The input end of the variable diameter pulley is fixedly connected to the output shaft of the second motor 12 mounted on the lower bracket 1. The variable diameter pulley is used to change the transmission speed transmitted to the second gear 7.

[0038] Preferably, the variable diameter pulley includes a first conical pulley 8 and a second conical pulley 10. The output shaft side of the first conical pulley 8 is fixedly connected to the second gear 7, and the input shaft side of the second conical pulley 10 is fixedly connected to the second motor 12. A transmission belt 9 is connected between the first conical pulley 8 and the second conical pulley 10. The speed can be adjusted by changing the mating diameter of the transmission belt 9 between the first conical pulley 8 and the second conical pulley 10.

[0039] The speed regulating mechanism also includes a rotating ring 11 and a lever 14. The rotating ring 11 is rotatably sleeved on the second cone wheel 10. One end of the lever 14 is rotatably connected to the lower support 1. A connecting rod 13 is connected between the lever 14 and the rotating ring 11. One end of the connecting rod 13 is rotatably connected to the rotating ring 11, and the other end is rotatably connected to one end of the lever 14. A sliding groove 15 is provided at the free end of the lever 14.

[0040] In this embodiment, by setting the meshing structure of the first gear 6 and the second gear 7, the rotation of the cutting blade 4 can be achieved through gear transmission, thereby ensuring the stability of the transmission process; by setting a variable diameter pulley and connecting its output end to the second gear 7, the speed of the power can be adjusted as needed during the transmission process, thereby making the speed of the cutting blade 4 adjustable.

[0041] The first conical wheel 8 and the second conical wheel 10 are connected by a transmission belt 9. During the transmission process, the effective diameter is changed by changing the contact position of the transmission belt 9 on the two conical wheels, thereby changing the transmission ratio and causing the output speed to change. This is beneficial for adjusting the operating state of the cutting blade 4 according to different working conditions.

[0042] The rotating ring 11 is sleeved on the second cone wheel 10. The rotating ring 11 can drive the second cone wheel 10 to change the transmission diameter. When the fixed-length transmission belt 9 is transmitting between the first cone wheel 8 and the second cone wheel 10, since the first cone wheel 8 is equipped with a reset component, when the transmission diameter of the second cone wheel 10 decreases, the transmission diameter of the first cone wheel 8 will increase accordingly. By cooperating, the transmission ratio can be changed, so that it can change position with the movement of the pressure plate 18. It is connected to the lever 14 through the connecting rod 13, thereby transmitting the displacement change to the adjustment structure and realizing the adjustment of the transmission state.

[0043] Please see Figures 1-8 As a preferred technical solution of the present invention, a sliding roller 16 is slidably arranged in the sliding groove 15. The sliding roller 16 is fixedly connected to a drive rod 17 installed on one side of the pressure plate 18. When the drive rod 17 moves up and down with the pressure plate 18, the lever 14 is driven to swing through the cooperation of the sliding roller 16 and the sliding groove 15.

[0044] In this embodiment, the sliding groove 15 is formed at the free end of the lever 14, providing a stable sliding space for the sliding roller 16. The sliding roller 16 is slidably disposed in the sliding groove 15 and can slide flexibly in the sliding groove 15. At the same time, it is fixedly connected to the drive rod 17 installed on one side of the pressure plate 18, realizing the connection between the drive rod 17 and the lever 14.

[0045] When the clamping plate 18 moves up and down adaptively according to the material thickness, it synchronously drives the drive rod 17 to reciprocate up and down. The drive rod 17 then drives the sliding roller 16, which is fixed to it, to move synchronously. While the sliding roller 16 slides in the sliding groove 15, it exerts a force on the free end of the lever 14, thereby driving the lever 14 to swing around its rotational connection point with the lower bracket 1. This method can smoothly and steadily convert the up and down displacement of the clamping plate 18 into the swinging motion of the lever 14, ensuring the continuity and stability of power transmission and avoiding jamming that may be caused by rigid connection. The sliding roller 16 and the sliding groove 15 are designed to ensure the smooth operation of the speed regulating mechanism. At the same time, the sliding roller 16 and the sliding groove 15 are designed to adapt to the positional deviation of the drive rod 17 when it moves up and down during the swing of the drive lever 14. This ensures that the speed regulating mechanism can accurately respond to the position adjustment of the pressing mechanism, realize the synchronous matching of the cutting speed of the cutting mechanism with the material thickness, effectively solve the problem of poor cutting quality caused by the fixed cutting speed of the existing device, improve the accuracy and quality of beef cutting, and enhance the overall operational stability of the device, so as to meet the requirements of large-scale meat processing for the reliability and practicality of the device.

[0046] Please see Figures 1-5 As a preferred technical solution of the present invention, the driving source is a first motor 3, which is used to provide constant conveying power for the two conveyor belts 2.

[0047] In this embodiment, by using the first motor 3 as the drive source, the two conveyor belts 2 maintain a constant conveying speed during operation, thereby ensuring that the material has a stable and consistent motion state when entering the cutting area, avoiding the phenomenon of material moving back and forth or stopping at the cutting position due to fluctuations in conveying speed. At the same time, the stable conveying speed helps the clamping mechanism maintain a continuous force state when pressing the material, allowing the clamping plate 18 to respond smoothly according to changes in material thickness, avoiding unstable clamping due to speed changes. In addition, during the cutting process, the constant conveying speed can keep the material feed speed coordinated with the cutting process, helping to reduce unevenness in the cutting process, thereby improving the flatness of the cut surface and the stability of the overall processing.

[0048] It should be noted that, in this document, terms such as "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
