Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically to a high-efficiency bread slicing machine. Background Technology

[0002] After bread is produced, it needs to be cut to size. However, currently, bread cutting is done manually by measuring and cutting, which is not only prone to size deviations but also inefficient and cannot meet the pace of mass production. To overcome these shortcomings, bread slicing machines have been invented on the market. For example, Chinese patent application CN108527504A discloses an automatic bread slicing machine, including a support frame, a conveyor belt above the support frame, a PLC controller fixed to one end of the support frame, and a first motor installed inside the support frame. This invention has a simple structure, is easy to operate, and is economical and practical. By controlling the first and second servo motors through the PLC controller, the distance between the first and second cutters can be adjusted, reducing measurement time, reducing labor intensity, and improving work efficiency. It effectively solves the problems of manual bread cutting, which is not only prone to size deviations but also inefficient and unable to meet the pace of mass production. An automatic lubrication device is also included, which lubricates the moving block and the first lead screw, reducing friction during rotation, saving energy consumption, improving work efficiency, and increasing the overall service life of the first lead screw and the moving block. However, the aforementioned automatic bread cutter has a complex structure, is inconvenient to operate, has a relatively low overall bread cutting efficiency, and cannot be adjusted for breads of different heights, resulting in poor adaptability. Therefore, improvements are needed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model proposes a high-efficiency bread slicing machine that is easy to operate, highly automated, and employs a dual-blade slicing method for high slicing efficiency. Furthermore, it can be adjusted to accommodate breads of different heights, making it highly adaptable.

[0004] To achieve the above technical solution, this utility model provides a high-efficiency bread slicing machine, comprising: a frame; a first blade holder assembly and a second blade holder assembly mounted on the frame, the first blade holder assembly and the second blade holder assembly being arranged parallel and spaced apart, and multiple cutting blades being staggered between the first blade holder assembly and the second blade holder assembly; a drive assembly mounted on the frame and located below the first blade holder assembly and the second blade holder assembly, the drive assembly including a drive motor, a transmission pulley, a convex shaft, a transmission rocker arm, a front shaft, a central shaft, and a rear shaft, wherein the drive motor is mounted at the bottom of the frame, the drive motor is connected to the transmission pulley via a transmission belt, a convex post is provided on the inner side of the transmission pulley, one end of the convex post shaft is connected to the convex post, the other end of the convex post shaft is connected to the bottom of the transmission rocker arm, a shaft fixing seat is provided at the top of the transmission rocker arm, and the central shaft is transversely mounted on the frame. The center of the shaft fixing seat is symmetrical about the center of the central shaft and is horizontally installed at both ends of the shaft fixing seat. The bottom of the first tool holder assembly is connected to the rear shaft through the first cutting shaft connecting block, and the bottom of the second tool holder assembly is connected to the front shaft through the second cutting shaft connecting block. A height limiting plate adjustment assembly is installed diagonally above the first tool holder assembly. The height limiting plate adjustment assembly includes a fixed shaft fixed laterally on the frame, an adjustment plate mounting block fixedly installed in the middle of the fixed shaft, a height adjustment plate horizontally installed through the adjustment plate mounting block, the back of the height adjustment plate being tightened by an adjustment bolt, and a height limiting plate fixed at the bottom of the height adjustment plate. The front end of the height limiting plate is inserted into the first tool holder assembly. A feed plate is installed on the frame and located diagonally above the first tool holder assembly. An output plate is installed on the frame and located diagonally below the second tool holder assembly.

[0005] In the above technical solution, during actual operation, the operator only needs to place the bread to be sliced ​​on the feeding plate and then gently push it diagonally downwards. The drive motor drives the transmission pulley to rotate. During the rotation of the transmission pulley, the transmission swing rod is driven by the convex column shaft to periodically and rapidly swing up and down. The transmission swing rod drives the front shaft and the rear shaft to periodically swing up and down. During the up and down swing, the front shaft and the rear shaft drive the first knife holder assembly and the second knife holder assembly to move up and down periodically, which can drive the multiple cutting blades that are alternately installed between the first knife holder assembly and the second knife holder assembly to move up and down alternately. When the bread passes through the cutting blades, the bread is sliced ​​evenly by the cutting blades. After the slices are completed, the bread slices are discharged from the discharge plate. In actual operation, if it is necessary to slice toast bread of different heights, the height of the height limiting plate can be adjusted by using the height limiting plate adjustment component to limit the height of the toast bread. This allows for better accommodating the top limit when slicing toast bread of different heights. In actual adjustment, simply loosen the adjusting bolt to allow the height adjusting plate to move, then move the height adjusting plate to drive the height limiting plate to move. Once the height limiting plate is moved to the appropriate height, tighten the adjusting bolt. The adjustment is very convenient.

[0006] Preferably, the first blade holder assembly includes a first blade holder body. Multiple first top shaft bolts are installed at intervals side-by-side on the top of the first blade holder body. A first cutting blade fixing top block is installed at the bottom of each first top shaft bolt. A first return spring is installed between the first cutting blade fixing top block and the first top shaft bolt. Multiple first cutting blade fixing bottom blocks are installed at intervals side-by-side on the bottom of the first blade holder body. Two first cutting blade shaft connecting blocks are also installed at intervals side-by-side on the bottom of the first blade holder body. The first cutting blade shaft connecting blocks are connected to the rear shaft. In actual operation, when the rear shaft moves up and down under the drive of the drive motor, it drives the first blade holder body to move up and down. When the first blade holder body moves up and down, it drives the cutting blades mounted on the first blade holder body to move up and down. When the toast bread comes into contact with the cutting blades, the moving cutting blades slice the toast bread.

[0007] Preferably, the second blade holder assembly includes a second blade holder body. Multiple second top shaft bolts are installed at intervals side-by-side on the top of the second blade holder body. A second cutting blade fixing top block is installed at the bottom of each second top shaft bolt. A second return spring is installed between the second cutting blade fixing top block and the second top shaft bolt. Multiple second cutting blade fixing bottom blocks are installed at intervals side-by-side on the bottom of the second blade holder body. Two second cutting blade shaft connecting blocks are also installed at intervals side-by-side on the bottom of the second blade holder body. The second cutting blade shaft connecting blocks are connected to the front shaft rod. In actual operation, when the front shaft rod moves up and down under the drive of the drive motor, it drives the second blade holder body to move up and down. When the second blade holder body moves up and down, it drives the cutting blades mounted on the second blade holder body to move up and down. When the toast bread comes into contact with the cutting blades, the moving cutting blades slice the toast bread.

[0008] Preferably, the structure in which multiple cutting blades are staggered between the first and second blade holder assemblies is as follows: the top of the first cutting blade is fixed to the first cutting blade fixing top block, and the bottom of the first cutting blade is fixed to the second cutting blade fixing bottom block; the top of the second cutting blade is fixed to the second cutting blade fixing top block, and the bottom of the second cutting blade is fixed to the first cutting blade fixing bottom block; the top of the third cutting blade is fixed to the first cutting blade fixing top block, and the bottom of the third cutting blade is fixed to the second cutting blade fixing bottom block; the top of the fourth cutting blade is fixed to the second cutting blade fixing top block, and the bottom of the fourth cutting blade is fixed to the first cutting blade fixing bottom block, and so on, staggered. This staggered installation of the cutting blades improves the efficiency of slicing toast bread.

[0009] Preferably, this high-efficiency bread slicing machine further includes: a blade holder positioning block assembly mounted on top of the first blade holder assembly and the second blade holder assembly. The blade holder positioning block assembly includes a central mounting shaft fixed laterally to the frame, with the blade holder positioning block mounted in the middle of the central mounting shaft. A first positioning rod and a second positioning rod extending downwards are respectively mounted at the front and rear ends of the blade holder positioning block. The first positioning rod contacts a first return spring mounted on top of the first blade holder body, and the second positioning rod contacts a second return spring mounted on top of the second blade holder body. By setting the blade holder positioning block assembly, the position of the first and second blade holder assemblies when moving upwards can be more accurately defined.

[0010] Preferably, a first positioning rod fine-tuning bolt is installed at the front end of the first positioning rod, and a second positioning rod fine-tuning bolt is installed at the front end of the second positioning rod, so that the positions of the first positioning rod and the second positioning rod can be better adjusted.

[0011] Preferably, both ends of the feed plate are equipped with feed side baffles to better limit the feed.

[0012] Preferably, discharge side baffles are installed at both ends of the discharge plate to better limit the discharge.

[0013] The advantages of this high-efficiency bread slicing machine are as follows: This high-efficiency bread slicing machine has a simple structure, reasonable design, convenient operation, and high degree of automation. It adopts a double-blade slicing method, resulting in high slicing efficiency. Furthermore, it can be adjusted for breads of different heights, making it highly adaptable. In actual operation, the operator only needs to place the bread to be sliced ​​on the feeding plate and gently push it diagonally downwards. The drive motor drives the transmission pulley to rotate. During the rotation of the transmission pulley, the transmission swing rod is driven by the convex shaft to periodically and rapidly swing up and down. The transmission swing rod drives the front and rear axles to periodically swing up and down. During the up-and-down swing, the front and rear axles respectively drive the first and second blade holder assemblies to move periodically up and down, thereby driving the multiple cutting blades, which are staggered between the first and second blade holder assemblies, to move up and down alternately. When the bread passes through the cutting blades, the blades slice the bread evenly. The sliced ​​bread is then discharged from the discharge plate. If you need to slice toast bread of different heights, you can also adjust the height of the height limit plate using the height limit plate adjustment component to limit the height of the toast bread. This will better accommodate the top limit when slicing toast bread of different heights. In actual adjustment, simply loosen the adjusting bolt to allow the height adjustment plate to move, then move the height adjustment plate to drive the height limit plate to move. After the height limit plate is moved to the appropriate height, tighten the adjusting bolt. The adjustment is very convenient. Attached Figure Description

In actual operation, when the rear axle 108 moves up and down under the drive of the drive motor 101, it will drive the first knife holder body 61 to move up and down. When the first knife holder body 61 moves up and down, it will drive the cutting blade 11 mounted on the first knife holder body 61 to move up and down. When the toast bread comes into contact with the cutting blade 11, the cutting blade 11 moving up and down will slice the toast bread.

[0028] The second blade holder assembly 8 includes a second blade holder body 81. Multiple second top shaft bolts 83 are installed at intervals along the top of the second blade holder body 81. A second cutting blade fixing top block 85 is installed at the bottom of each second top shaft bolt 83. A second return spring 84 is installed between the second cutting blade fixing top block 85 and the second top shaft bolt 83. Multiple second cutting blade fixing bottom blocks 86 are installed at intervals along the bottom of the second blade holder body 81. Two second cutting blade shaft connecting blocks 82 are also installed at intervals along the bottom of the second blade holder body 81. The second cutting blade shaft connecting blocks 82 are connected to the front shaft rod 106. In actual operation, when the front shaft rod 106 moves up and down under the drive of the drive motor 101, it drives the second blade holder body 81 to move up and down. The up-and-down movement of the second blade holder body 81 drives the cutting blades 11 mounted on the second blade holder body 81 to move up and down. When the toast bread comes into contact with the cutting blades 11, the up-and-down moving cutting blades 11 slice the toast bread.

[0029] The structure in which multiple cutting blades 11 are staggered between the first blade holder assembly 6 and the second blade holder assembly 8 is as follows: the top of the first cutting blade 11 is fixed to the first cutting blade fixing top block 64, and the bottom of the first cutting blade 11 is fixed to the second cutting blade fixing bottom block 86; the top of the second cutting blade 11 is fixed to the second cutting blade fixing top block 85, and the bottom of the second cutting blade 11 is fixed to the first cutting blade fixing bottom block 66; the top of the third cutting blade 11 is fixed to the first cutting blade fixing top block 64, and the bottom of the third cutting blade 11 is fixed to the second cutting blade fixing bottom block 86; the top of the fourth cutting blade 11 is fixed to the second cutting blade fixing top block 85, and the bottom of the fourth cutting blade 11 is fixed to the first cutting blade fixing bottom block 66, and so on, in an alternating manner. This staggered installation of the cutting blades 11 improves the efficiency of slicing toast bread.

The transmission swing rod 105 drives the front shaft 106 and the rear shaft 108 to swing up and down periodically. During the up and down swing, the front shaft 106 and the rear shaft 108 respectively drive the first knife holder assembly 6 and the second knife holder assembly 8 to move up and down periodically. This can drive the multiple cutting blades 11, which are installed alternately between the first knife holder assembly 6 and the second knife holder assembly 8, to move up and down alternately. When the toast bread passes through the cutting blades 11, the cutting blades 11 slice the toast bread evenly.

[0031] The height limiting plate adjustment assembly 7 is installed diagonally above the first blade holder assembly 6. The height limiting plate adjustment assembly 7 includes a fixed shaft 71 fixed laterally to the frame 1, an adjustment plate mounting block 72 fixedly installed in the middle of the fixed shaft 71, a height adjusting plate 73 installed diagonally downwards through the adjustment plate mounting block 72, and the back of the height adjusting plate 73 abutted against by an adjusting bolt 74. A height limiting plate 75 is fixed to the bottom of the height adjusting plate 73, and the front end of the height limiting plate 75 is inserted into the first blade holder assembly 6. In actual operation, if it is necessary to slice toast bread of different heights, the height of the height limiting plate 75 can be adjusted using the height limiting plate adjustment assembly 7 to limit the height of the toast bread, thus better accommodating the top limit when slicing toast bread of different heights. In actual adjustment, simply loosen the adjusting bolt 74 to allow the height adjusting plate 73 to move, then move the height adjusting plate 73 to move the height limiting plate 75 to the appropriate height, and then tighten the adjusting bolt 74. The adjustment is very convenient.

[0032] A tool holder positioning block assembly 9 is installed on top of the first tool holder assembly 6 and the second tool holder assembly 8. The tool holder positioning block assembly 9 includes a central mounting shaft 91 fixed laterally to the frame 1. A tool holder positioning block 92 is installed in the middle of the central mounting shaft 91. A first positioning rod 93 and a second positioning rod 94 extending downwards are respectively installed at the front and rear ends of the tool holder positioning block 92. The first positioning rod 93 contacts a first return spring 63 installed on the top of the first tool holder body 61, and the second positioning rod 94 contacts a second return spring 84 installed on the top of the second tool holder body 81. By setting the tool holder positioning block assembly 9, the position of the first tool holder assembly 6 and the second tool holder assembly 8 when moving upwards can be more accurately defined. A first positioning rod fine-tuning bolt 96 is installed at the front end of the first positioning rod 93, and a second positioning rod fine-tuning bolt 95 is installed at the front end of the second positioning rod 94, so that the positions of the first positioning rod 93 and the second positioning rod 94 can be better adjusted.

[0034] The discharge plate 3 is installed on the frame 1 and located diagonally below the second tool holder assembly 8. Both ends of the discharge plate 3 are equipped with discharge side baffles 5 to better limit the discharge.

[0035] This high-efficiency bread slicer features a simple structure, reasonable design, convenient operation, and a high degree of automation. It employs a dual-blade slicing method, resulting in high slicing efficiency and adaptability to different bread heights. In actual operation, the operator simply places the bread to be sliced ​​on the feed plate 2 and gently pushes it diagonally downwards. The drive motor 101 drives the transmission pulley 102 to rotate. During rotation, the transmission pulley 102, via the convex shaft 104, drives the transmission swing arm 105 to periodically and rapidly swing up and down. The transmission swing arm 105 drives the front shaft 106 and rear shaft 108 to periodically swing up and down. During this swinging motion, the front shaft 106 and rear shaft 108 respectively drive the first blade holder assembly 6 and the second blade holder assembly 8 to periodically move up and down. This causes the multiple cutting blades 11, which are staggered between the first and second blade holder assemblies 6 and 8, to move up and down alternately. When the bread passes through the cutting blades 11, it is sliced ​​evenly. The sliced ​​bread is then discharged from the discharge plate 3. If you need to slice toast bread of different heights, you can adjust the height of the height limiting plate 75 using the height limiting plate adjustment component 7 to limit the height of the toast bread, thus better accommodating the top limit when slicing toast bread of different heights. In actual adjustment, simply loosen the adjusting bolt 74 to allow the height adjusting plate 73 to move, then move the height adjusting plate 73 to move the height limiting plate 75 to the appropriate height, and finally tighten the adjusting bolt 74. The adjustment is very convenient.

[0036] The above description is only a preferred embodiment of the present utility model. However, the present utility model should not be limited to the content disclosed in the embodiment and the accompanying drawings. Therefore, any equivalent or modified embodiments made without departing from the spirit disclosed in the present utility model shall fall within the protection scope of the present utility model.
