[0002] In traditional food processing, breaking bread by hand usually relies on manual operation. Workers need to repeat the breaking action for a long time, which is not only labor-intensive and inefficient, but also prone to occupational diseases such as tenosynovitis and joint pain due to frequent hand exertion, affecting the health of the operators. At the same time, manual breaking of bread has problems such as uneven force control, inconsistent bread piece size, and difficulty in ensuring hygiene, making it difficult to meet the needs of modern food processing industry for standardized, large-scale and automated production.

Two third cylinders are located on the left side of the device base and are fixedly connected to the device base. The output end of the third cylinder is fixedly connected to the clamping plate. The positions of the first cylinder, the second cylinder, and the third cylinder are on the same longitudinal plane. The first proximity switch is fixedly installed at the center line position of the third cylinder and the sensing end is aligned with the direction of the conveyor belt.

[0006] Preferably, the transmission structure includes a servo motor, a transmission chain, and a rotating shaft.

[0010] The beneficial effects of this utility model are:

[0011] Compared with existing technologies, the advantages of this utility model are:

[0012] This device, through its structural design, places the steamed buns (which need to be simulated by hand) onto a conveyor belt. The transmission mechanism then activates, starting the conveyor belt. As the belt moves, the buns placed on the right side are sequentially transferred to the left side. When a bun reaches the left side and is detected by the first proximity switch, the conveyor belt stops. A third cylinder then activates, moving a clamping plate towards the bun on the conveyor belt, squeezing and holding the bun from the center. The third cylinder stops operating when the bun is squeezed by the clamping plate. The end of the clamping plate that contacts the bun is rounded, preventing a straight line. Next, the steamed bun is cut in half. When the third cylinder stops operating, the first cylinder operates, causing the second cylinder to move downwards. This moves the bun-breaking plate down to a position close to the clamping plate, after which the first cylinder stops operating. Then, the second cylinder operates, causing the bun-breaking plate to move towards the steamed bun on the conveyor belt, squeezing and clamping the bun from the middle. The end of the bun-breaking plate that contacts the bun does not directly cut it in half. When the bun-breaking plate has squeezed and clamped the bun, the second cylinder stops operating. At this time, the first and third cylinders reset, and the reset of the first cylinder causes the second cylinder to move upwards. The first cylinder moves upward, causing the splitting plate to break the bread in half, mimicking the action of hand-breaking. The second cylinder then resets, causing the clamping plate to reset as well. The lower half of the separated bread remains on the conveyor belt, while the upper half remains above the splitting plate. After the first cylinder resets, the operation stops. At this point, the transmission structure and the push cylinder operate simultaneously. The transmission structure drives the conveyor belt, causing the remaining lower half of the separated bread to fall to the finished product collection point and transferring the next bread to be split between the two clamping plates. The push cylinder then operates... One end of the transmission plate moves, while the other end drives a rotating shaft to rotate on the device base. The rotation of the shaft causes a connecting plate to rotate around the shaft, which in turn causes the connecting plate to rotate around the shaft's center. This rotation of the connecting plate moves the first and second cylinders. When the second cylinder rotates, it moves the bread-breaking plate along with it. This movement causes the upper part of the separated bread to move from its position aligned with the conveyor belt to the finished product collection point. Once the upper part of the bread is collected, the cylinder is pushed to reset, resetting the bread-breaking plate and starting the processing of the next bread. Compared to existing technologies, this invention, through the inclusion of a conveyor belt assembly, clamping mechanism, bread-breaking mechanism, and linkage drive components, achieves fully automated operation of the entire process of bread block transmission, clamping, breaking, and separation collection. The device uses a cylinder-driven mechanical structure to simulate manual bread-breaking, ensuring the integrity of the bread blocks. This technology effectively reduces manual labor intensity and improves production efficiency and product consistency. Attached Figure Description

[0022] Please see Figure 1-5 This utility model provides a technical solution: a bread-breaking machine, including a transmission structure 1, a device base 2, a conveyor belt 3, a push cylinder 4, a transmission plate 5, a rotating shaft 6, a connecting plate 7, a first cylinder 8, a second cylinder 9, a bread-breaking plate 10, a third cylinder 11, a clamping plate 12, and a first proximity switch 13. The transmission structure 1 is installed on the right side of the device base 2. One end of the conveyor belt 3 is installed on the transmission structure 1, and the other end of the conveyor belt 3 is installed on the left side of the device base 2. The push cylinder 4 is located inside the device base 2 and one end is rotatably connected to the device base 2. The output end of the push cylinder 4 is rotatably connected to one end of the transmission plate 5, and the other end of the transmission plate 5 is fixedly connected to the rotating shaft 6. One end of the rotating shaft 6 is located inside the device base 2 and is rotatably connected to the device base 2. The other end of the rotating shaft 6 is fixedly connected to the connecting plate 7. The connecting plate 7 is fixedly connected to the first cylinder 8. Two second cylinders 9 are fixedly installed at the output end of the first cylinder 8. The output end of the second cylinder 9 is fixedly connected to the bread-breaking plate 10. Two third cylinders 11 are located on the left side of the device base 2 and are fixedly connected to the device base 2. The output end of the third cylinder 11 is fixedly connected to the clamping plate 12. The positions of the first cylinder 8, the second cylinder 9 and the third cylinder 11 are on the same longitudinal plane. The first proximity switch 13 is fixedly installed at the center line position of the third cylinder 11 and the sensing end is aligned with the direction of the conveyor belt 3.

[0023] In this utility model, the transmission structure 1 includes a servo motor 101, a transmission chain 102, and a rotating shaft 103. The servo motor 101 is fixedly installed inside and connected to the device base 2. One end of the transmission chain 102 is installed on the output end of the servo motor 101, and the other end of the transmission chain 102 is installed on the rotating shaft 103. The rotating shaft 103 is rotatably installed on the device base 2. One end of the conveyor belt 3 is installed on the rotating shaft 103. The servo motor 101 in the transmission structure 1 drives the rotating shaft 103 to rotate through the transmission chain 102, and the rotation of the rotating shaft 103 drives the conveyor belt 3 to start running.

[0024] In this utility model, the device base 2 is provided with an air nozzle 14. The air nozzle 14 is installed on the device base 2 and its output end is aligned with the position of the bread-breaking board 10. The air nozzle 14 located on the device base 2 can facilitate the staff to blow the bread that has fallen to the finished product collection point instead of following the procedure to the finished product collection point.

[0025] In this utility model, a control panel 15 is provided on the device base 2. The control panel 15 is fixedly installed on the device base 2. The control panel 15 is electrically connected to the transmission structure 1, the push cylinder 4, the first cylinder 8, the second cylinder 9, the third cylinder 11, and the first proximity switch 13. The control panel 15 located on the device base 2 facilitates the centralized control of the internal electrical components of the device by the staff.

[0026] In this utility model, a second proximity switch 16 is provided on the device base 2. The second proximity switch 16 is fixedly installed on the right side of the device base 2 and its sensing end is aligned with the rightmost position of the conveyor belt 3. The second proximity switch 16 can sense the steamed bun to be processed placed on the conveyor belt 3 and automatically start the transmission structure 1 to run, thereby improving the automation efficiency of the overall device.

[0027] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0028] In this implementation scheme: the control panel 15 located on the device base 2 allows for centralized control of the internal electrical components by the operator. During use, the bread to be manually broken is placed on the right side of the conveyor belt 3, and the finished product collection area is placed on the left side of the device base 2. At this time, the servo motor 101 in the transmission structure 1 starts and drives the rotating shaft 103 to rotate via the transmission chain 102. The rotation of the rotating shaft 103 drives the conveyor belt 3 to start running. The second proximity switch 16 can sense the bread to be processed placed on the conveyor belt 3 and automatically start the transmission structure 1, improving the overall automation efficiency of the device.

[0029] Conveyor belt 3 transports the steamed buns placed on its right side to its left side sequentially. When a bun moves to the left side of conveyor belt 3 and is detected by the first proximity switch 13, conveyor belt 3 stops. The third cylinder 11 activates, moving the clamping plate 12 towards the bun on conveyor belt 3, squeezing and clamping the bun from the middle. When the bun is squeezed by the clamping plate 12, the third cylinder 11 stops operating. The end of the clamping plate 12 that contacts the bun is rounded, preventing it from directly cutting the bun in half. When the third cylinder 11 stops operating, the first cylinder 8 activates, moving the second cylinder 9 downwards. This moves the bun-breaking plate 10 downwards to a position close to the clamping plate 12, after which the first cylinder 8 stops operating. Then, the second cylinder 9 activates, moving the bun-breaking plate 10 towards the bun on conveyor belt 3, squeezing and clamping the bun from the middle. The end of the bread-breaking board 10 that contacts the bread will not directly cut the bread in half. When the bread-breaking board 10 squeezes and clamps the bread, the second cylinder 9 stops operating. At this time, the first cylinder 8 and the third cylinder 11 reset. The reset of the first cylinder 8 drives the second cylinder 9 to move upward. The upward movement of the second cylinder 9 drives the bread-breaking board 10 to break the bread in half, simulating the action of breaking it by hand. The reset of the third cylinder 11 drives the clamping plate 12 to reset.

[0030] The lower half of the split bread remains on conveyor belt 3, while the upper half remains above the bread-breaking plate 10. After the first cylinder 8 resets and stops operating, the transmission structure 1 and the push cylinder 4 operate simultaneously. The transmission structure 1 drives the conveyor belt 3, causing the remaining lower half of the split bread to fall to the finished product collection point and transferring the next bread to be broken between the two clamping plates 12. The push cylinder 4 moves one end of the transmission plate 5, and the other end of the transmission plate 5 drives the rotating shaft 6 to rotate on the device base 2. The rotation of the rotating shaft 6 causes the connecting plate 7 to rotate around the rotating shaft 6, and the rotation of the connecting plate 7 causes the first cylinder 8 and the second cylinder 9 to move. When the second cylinder 9 rotates, it moves the bread-breaking plate 10 along with it. The movement of the bread-breaking plate 10 causes the upper part of the separated bread to move from its position on the conveyor belt 3 to the finished product collection area. At this time, the second cylinder 9 resets, causing the bread-breaking plate 10 to reset as well, allowing the upper part of the bread to fall into the finished product collection area. Once the upper part of the bread has been collected, the cylinder 4 is pushed to reset, causing the bread-breaking plate 10 to reset as well, and the processing of the next bread begins. The air nozzle 14 located on the device base 2 allows workers to easily blow any bread that has fallen outside the finished product collection area back to the collection area.
