Description

Technical Field

[0001] This application relates to the technical field of sandwich production equipment, and in particular to a sandwich cutting and adjustment unit and a sandwich production line. Background Technology

[0002] In the industrial production of sandwiches, the sandwich dough is repositioned on the production line and then cut in half to form a sandwich.

[0003] After the sandwich dough is cut in half, there are generally two ways to process the sandwich: 1. Fully Automated Production Line Processing: Freshly cut sandwiches undergo differential speed conveying on the production line to separate two opposing sandwiches at the appropriate distance. The separated sandwiches then undergo multiple position adjustments during the conveying process, before being transported to different conveyor lines via a lifting conveyor belt. On the corresponding conveyor lines, the sandwiches are aligned so that their right-angled edges align with the conveyor line baffles. Subsequently, the sandwiches are conveyed onto a partition conveyor belt on different conveyor lines, where they stand upright for subsequent packaging in automated packaging equipment. 2. Manual Assisted Processing: The freshly cut sandwiches are conveyed on the conveyor line, picked up by workers and placed upright on the partition conveyor belt, and then transported to the corresponding packaging equipment for packaging.

[0004] In terms of process flow, manual labor is actually more efficient and has a lower defect rate per unit time. However, manual methods cannot be used for large-scale production, which is a constraint on production and incurs labor costs. Therefore, for large-scale industrial production, fully automated production lines are more suitable. These lines only require workers to inspect the conveyor belts for defective products (such as improperly cut or misplaced sandwiches) and remove them. However, this method requires a large number of long conveyor lines, resulting in a larger overall space occupation and higher maintenance and equipment purchase costs. Therefore, the production line design from sandwich dough cutting to sandwich packaging has lower input costs and lower efficiency. Summary of the Invention

[0005] In order to improve the shortcomings of low input cost and low work efficiency in the production line design from sandwich dough cutting to sandwich packaging, this application provides a sandwich cutting adjustment unit and a sandwich production line.

[0006] The sandwich cutting adjustment unit provided in this application adopts the following technical solution: A sandwich cutting adjustment unit, including Base frame; The middle support plate is erected on the base frame; There are two support plates, which are rotatably connected to both sides of the middle support plate. A side frame is fixed on the side away from the middle support plate, and a frame plate is fixed on the top of the side frame. The front baffle is a right-angled plate, located at the front end of the middle support plate; The telescopic cylinder is mounted directly above the middle support plate, and a cutter is installed at the bottom of the piston rod; The flipping assembly, mounted on the base frame, is used to rotate the receiving plate from a horizontal position downwards to a vertical position and then reset it. The base plate is slidably connected to the side frame. A compression spring is fixedly installed on the inner wall of the side frame near the front baffle. The other end of the compression spring is fixedly connected to the base plate. A flip plate is rotatably connected to the base plate. The adjustment plate is slidably connected to the side frame and rotatably connected to a drive rod, the other end of which is rotatably connected to the flip plate. The drive cylinder is fixed on the side frame, and the piston rod is fixed to the adjusting plate; When the adjustment plate is at its furthest position from the base plate, the flip plate is in contact with the side frame and directly opposite the adjustment plate. When the adjusting plate comes into contact with the base plate, the flip plate rotates and stands up, and the adjusting plate will cause the base plate to slide and compress the compression spring.

[0007] Optionally, when the adjusting plate abuts against the base plate, the angle between the flipping plate and the base plate is less than 90°. At this time, the distance between the flipping plate and the plane where the front end of the middle support plate is located is less than the distance between the base plate and the plane where the front end of the middle support plate is located.

[0008] Optionally, the end of the flip plate away from the substrate is bent, and when the flip plate abuts against the side frame, the bent part of the flip plate is located inside the side frame.

[0009] Optionally, the tilting assembly includes a tilting cylinder, a traction rod, a sliding frame, and an upper top spring; The sliding frame is slidably connected to the base frame, and the top spring is mounted on the base frame. The top of the top spring is fixedly connected to the bottom of the sliding frame. There are multiple traction rods, which are rotatably connected to both sides of the sliding frame. The other end of the traction rod is rotatably connected to the upper support plate. The upper surface of the sliding frame has protrusions on both sides. The upper spring will drive the sliding frame to move to the position where the traction rod abuts against the protrusions on both sides of the sliding frame. At this time, the support plate is in a horizontal state. After the support plate is in a horizontal state, it cannot continue to rotate upward. The tilting cylinder is installed inside the base frame. The top of the piston rod passes through the sliding frame and is fixed with a pull-down plate. During the resetting process of the piston rod of the tilting cylinder, the pull-down plate will abut against the top of the sliding frame and drive the sliding frame to move down to the position where the tilting plate is in a vertical state.

[0010] Optionally, the piston rod of the telescopic cylinder is equipped with a downward moving frame, the downward moving frame has a stabilizing hole, a stabilizing rod is slidably connected to the stabilizing hole, a top plate is fixed to the top of the stabilizing rod, the bottom of the stabilizing rod is fixedly connected to the top of the front baffle, and the bottom of the front baffle abuts against the upper surface of the middle support plate. The length of the stabilizer bar is greater than the height of the cutter body; As the flip plate rotates downwards, the lower frame moves upwards, causing the front baffle to move to a position that does not obstruct the movement of the sandwich.

[0011] Optionally, a center ring plate is fixed between the front baffle and the lower frame of the stabilizer bar, and a stabilizer spring is sleeved on the stabilizer bar. The top end of the stabilizer spring abuts against the lower frame of the stabilizer bar, and the bottom end abuts against the center ring plate.

[0012] This application also provides a sandwich production line using the following technical solution: A sandwich production line includes the sandwich cutting and adjusting unit described above, and also includes a main conveyor, a baffle adjusting device, and an auxiliary conveyor; The main conveyor is a belt conveyor used for transporting sandwich prep materials; The material blocking adjustment equipment includes a top frame, an equipment platform, a first electric slide, a mounting frame, and a main baffle. The top frame is erected above the main conveyor, the equipment platform is installed on the top frame, the first electric slide is vertically installed on the equipment platform, the mounting frame is installed at the bottom of the slide of the first electric slide, and the main baffles are installed in rows on the mounting frame. The main baffles are right-angled plates and are on the moving path of the sandwich blank. When the mounting bracket is moved to its lowest position, the sandwich blank on the main conveyor can move to a position that abuts against the main baffle and fits against the side walls of the main baffle. Multiple sandwich cutting adjustment units are located at the end of the main conveyor; The auxiliary conveyor is a partition belt conveyor, located at the end of multiple sandwich cutting and adjusting units, used to receive sandwiches pushed out from the receiving plate. The conveying direction of the main conveyor is parallel to that of the auxiliary conveyor. The auxiliary conveyor starts intermittently. The partitions of the auxiliary conveyor are in groups of two. After each pause, the sandwich pushed out from the receiving plate will move between the two partitions in each group of the auxiliary conveyor. The auxiliary conveyor will pass through the sandwich packaging equipment.

[0013] Optionally, the equipment platform is slidably connected to the top frame, with the sliding direction parallel to the conveying direction of the main conveyor; The top frame is equipped with a second electric slide table. The slide table of the second electric slide table is fixedly connected to the equipment table, which drives the equipment table to slide. After the sandwich blank and the main baffle are in contact and fit together, the main baffle moves together with the sandwich blank to the sandwich cutting and adjustment unit.

[0014] Optionally, the mounting bracket is also equipped with multiple secondary baffles. The secondary baffles are right-angled plates with openings opposite to the main baffles. The secondary baffles are closer to the sandwich cutting adjustment unit and opposite to the main baffles, and are used to transfer the sandwich blanks to the receiving plate.

[0015] Optionally, multiple guide plates are fixed on the frame of the auxiliary conveyor. The guide plates are arranged in groups of two. The distance between the two guide plates in a group gradually increases in the direction towards the receiving plate. When the auxiliary conveyor stops, the position of the guide plate is opposite to the partition plate, which is used to guide the sandwich auxiliary into the space between the two partition plates.

[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. After the sandwich is cut on the middle support plate, the two support plates rotate downwards. During the downward rotation of the support plates, the drive cylinder drives the adjustment plate to slide, and the drive rod drives the flipping plate to rotate and stand up. During this process, the flipping plate will abut against the right angle edge of the sandwich and drive the sandwich to rotate to the upright position. Then the adjustment plate will drive the base plate to move together and push the upright sandwich out. Thus, the sandwich cutting, position adjustment and standing processes are realized on one machine, which changes the sandwich production line layout, saves equipment costs and improves production efficiency. 2. Due to the sliding frame and the top spring, the receiving plate is kept stably in a horizontal state under normal conditions. The tilting cylinder drives the receiving plate to rotate downward to a vertical state by pulling down the sliding frame after the pull-down plate abuts against it. Compared with the method of using the tilting cylinder to drive the sliding frame to move up and down, this method can effectively improve the stability of the receiving plate in a horizontal state and reduce the probability of inaccurate position of the receiving plate caused by the error of the tilting cylinder piston rod movement position. 3. The front baffle can position the sandwich blanks fed onto the receiving plate and can also move upward with the upper moving frame before the receiving plate flips, thus not interfering with the sandwich standing process and improving the quality of the sandwiches. Due to the setting of the stabilizer bar and the top plate, when the upper moving frame moves down to the point where the front baffle abuts against the middle receiving plate, the cutter will not block the movement path of the sandwich blanks, so that the telescopic cylinder can simultaneously control the front baffle and the cutter to move in a stable position. 4. On a sandwich production line with a sandwich cutting and adjustment unit, multiple conveyors are eliminated. The sandwich dough position adjustment, cutting, sandwich position adjustment and standing processes can be completed using only a main conveyor, auxiliary conveyor, baffle adjustment equipment and sandwich cutting and adjustment unit. This not only saves equipment space but also effectively saves total equipment investment costs and improves the efficiency of sandwich industrial production by shortening the path. The main baffle and the auxiliary baffle on the mounting frame allow for position adjustment of the sandwich prep through the main baffle. During the rearward movement of the mounting frame, the sandwich prep passing through the main baffle is pushed onto the middle support plate via the rear baffle, making the position adjustment and movement of the sandwich prep more stable.

[0019] The following is in conjunction with the appendix Figure 1-12 This application will be described in further detail.

[0020] This application discloses a sandwich cutting and adjusting unit and a sandwich production line.

[0021] refer to Figure 1 The sandwich production line includes a main conveyor 6, a material blocking adjustment device 7, a sandwich cutting adjustment unit, and an auxiliary conveyor 8.

[0022] refer to Figure 1 and Figure 2 The main conveyor 6 is a food-grade belt conveyor used for conveying sandwich dough. The sandwich dough is arranged in a matrix on the main conveyor 6. Multiple sandwich cutting and adjusting units are arranged side-by-side at the end of the main conveyor, used to cut the sandwich dough, stand the sandwiches upright, and adjust their orientation. A retaining adjustment device 7 is located above the main conveyor 6 to adjust the position of the sandwich dough on the main conveyor 6 and push the adjusted sandwich dough onto the sandwich cutting and adjusting units. The auxiliary conveyor 8 is a food-grade partitioned belt conveyor located at the end of the multiple sandwich cutting and adjusting units, used to receive the sandwiches from the units. The conveying direction of the main conveyor 6 is perpendicular to the conveying direction of the auxiliary conveyor 8. The auxiliary conveyor 8 starts intermittently. The partitions of the auxiliary conveyor 8 are grouped in pairs; after each pause, the sandwiches on the sandwich cutting and adjusting units move between the two partitions in each group on the auxiliary conveyor 8. Multiple guide plates 81 are fixed on the frame of the auxiliary conveyor 8. The guide plates 81 are grouped in pairs, and the distance between the two guide plates 81 in a group gradually increases in the direction towards the receiving plate 3. When the auxiliary conveyor 8 stops, the guide plates 81 are positioned opposite the partitions to guide the sandwiches between the two partitions. The auxiliary conveyor 8 passes through the sandwich packaging equipment.

[0023] The sandwich prep rolls are conveyed as a whole on the main conveyor 6. After being adjusted to a suitable cutting position by the baffle adjustment device 7 and pushed onto the sandwich cutting adjustment unit, the prep rolls are cut and stood upright, with all sandwiches facing the same direction. Finally, the sandwiches are pushed into the partitions of the auxiliary conveyor 8 for further conveying. The guide plate effectively improves the stability of the sandwich prep rolls as they are pushed onto the auxiliary conveyor 8. The upright, equally oriented sandwiches then pass through the sandwich packaging equipment on the auxiliary conveyor 8 for packaging. Compared to existing sandwich production lines, this production line effectively reduces the number of conveyors and the length of the conveying path, saving overall equipment investment costs, reducing factory space requirements, and improving production efficiency through shorter paths.

[0024] refer to Figure 3 The sandwich cutting and adjusting unit includes a base frame 1, a telescopic cylinder 2, a receiving plate 3, a middle receiving plate 11, a cutter 21, and a front baffle 2224. The base frame 1 is located at the end of the main conveyor 6. The middle receiving plate 11 is mounted on the base frame 1, and a cutting groove 111 is formed in the middle of the upper surface of the middle receiving plate 11. There are two receiving plates 3, which are rotatably connected to the two sides of the middle receiving plate 11. The rotation axis of the receiving plates 3 is parallel to the conveying direction of the main conveyor 6. A side frame 31 is fixed on the side of the receiving plate 3 away from the middle receiving plate 11, and a frame plate 32 is fixed on the top of the side frame 31. The middle receiving plate 11 has a clamping plate structure on both sides, so that the receiving plate 3 cannot continue to rotate upward after rotating to the horizontal position. The base frame 1 is provided with a flipping assembly 5 that drives the receiving plate 3 from the horizontal position to the vertical position and resets it. The space between the receiving plate 3, the side frame 31, and the frame plate 32 is sufficient to place the sandwich blank.

[0025] refer to Figure 3 Figure 4 and Figure 5 The telescopic cylinder 2 is vertically mounted directly above the middle support plate 11, with the piston rod end pointing downwards and fixedly installed with the cutter 21. In this embodiment, the cutter 21 is an ultrasonic food cutter. The cutter 21 is located directly above the cutting groove 11 and can extend into the cutting groove 11. A lower moving frame 22 is mounted on the piston rod of the telescopic cylinder 2. The lower moving frame 22 has two stabilizing holes 221. A stabilizing rod 222 slides vertically within the stabilizing holes 221, and a top plate 2221 is fixed to the top of the stabilizing rod 222. A middle ring plate 2222 is fixed to the stabilizing rod 222 below the lower moving frame 22. A stabilizing spring 2223 is sleeved on the stabilizing rod 222. The top of the stabilizing spring 2223 abuts against the lower moving frame 22, and the bottom of the stabilizing spring abuts against the middle ring plate 2222, so that the top plate 2221 abuts against the top of the lower moving frame 22. The length of the stabilizing rod 222 is greater than the height of the cutter body 21. The front baffle 2224 is installed at the bottom of the two stabilizer bars 222. The front baffle 2224 is a right-angle plate with its opening facing the main conveyor 6. The part of the middle support plate 11 closest to the auxiliary conveyor 8 is the front end, and the front baffle 2224 is located above the front end of the middle support plate 11.

[0026] Combination Figure 3 and Figure 4 When the front baffle 2224 abuts against the middle support plate 11, the space between the cutter 21 and the middle support plate 11 is sufficient for the sandwich blank to pass through. Afterward, as the cutter 21 continues to move downward, the lowering frame 22 will continuously compress the stabilizing spring 2223. A clearance hole is provided in the middle of the front baffle 2224 to allow the cutter 21 to pass.

[0027] Combination Figure 5The piston rod of the telescopic cylinder 2 will move up to a position where the front baffle 2224 will not obstruct the movement of the sandwich. As the sandwich blank enters above the middle support plate 11, the sandwich blank will abut against the front baffle 2224 and move to a position where one of the diagonals of the sandwich blank is directly opposite the cutting groove 11.

[0028] The side frame 31 is also provided with an ejection assembly 4 that adjusts the sandwich so that its inclined surface faces the auxiliary conveyor 8 and pushes it onto the auxiliary conveyor 8 during the process of rotating the receiving plate 3 to a vertical position.

[0029] After the sandwich dough enters the middle support plate 11, it abuts against the front baffle 2224, ensuring that the sandwich dough is positioned at the same angle before cutting, thus improving the consistency of sandwich cutting. Then, the telescopic cylinder 2 drives the cutter 21 downwards to cut the sandwich dough. The cutting groove 111 allows the cutter 21 to extend, improving its protection and ensuring the sandwich dough is cut. The telescopic cylinder 2 then drives the cutter 21 upwards, and after it abuts against the top plate 2221 and the lower moving frame 22, it begins to drive the front baffle 2224 upwards. Subsequently, the flipping assembly 5 drives the receiving plate 3 downwards, and the sandwiches stand up as the receiving plate 3 rotates. During this process, the push-out assembly 4 ensures that the inclined surfaces of the sandwiches are uniformly facing the auxiliary conveyor 8, and after the receiving plate 3 is in a vertical position, the sandwiches are pushed between two partitions within a set on the auxiliary conveyor 8. In this way, the sandwich dough can be cut, uniformly oriented, and stood up on a single machine, optimizing the sandwich production line, improving sandwich production efficiency, and reducing equipment investment costs.

[0030] refer to Figure 6 , Figure 7 and Figure 8 The launch component 4 includes a drive cylinder 41, a base plate 42, a tilting plate 43, and an adjusting plate 44. The base plate 42 is slidably connected to the side frame 31. A compression spring 421 is fixedly mounted on the inner wall of the side frame 31 near the auxiliary conveyor 8, with the other end of the spring 421 fixedly connected to the base plate 42. The tilting plate 43 is rotatably connected to the end of the base plate 42 away from the compression spring 421. The adjusting plate 44 is slidably connected to the side frame 31 and located at the end of the base plate 42 away from the compression spring 421. A drive rod 441 is rotatably connected to the adjusting plate 44, with the other end of the drive rod 441 rotatably connected to the tilting plate 43. The drive cylinder 41 is installed on the side of the side frame 31 away from the middle support plate 11. The drive cylinder 41 is an electric cylinder, with the piston rod end fixedly connected to the adjusting plate 44. The extension and retraction of the piston rod drives the adjusting plate 44 to slide on the side frame 31.

[0031] Combination Figure 6Before the piston rod of the drive cylinder 41 extends, the distance between the adjusting plate 44 and the base plate 42 is the greatest. The flip plate 43 rotates to a position that fits against the side frame 31 and is directly opposite the adjusting plate 44. The end of the flip plate 43 away from the base plate 42 is bent and located inside the side frame 31.

[0032] Combination Figure 7 When the drive cylinder 41 moves the adjustment plate 44 to abut against the base plate 42, the angle between the flip plate 43 and the base plate 42 is less than 90°, and the distance between the flip plate 43 and the plane where the front end of the middle support plate 11 is located is less than the distance between the base plate 42 and the plane where the front end of the middle support plate 11 is located.

[0033] Combination Figure 8 When the piston rod of the drive cylinder 41 extends to its farthest distance, the adjusting plate 44 will abut against the base plate 42 and compress the compression spring 421, so that the front end of the flipping plate 43 extends directly above the belt of the auxiliary conveyor 8.

[0034] During the flipping of the receiving plate 3, the adjusting plate 44 moves to a position that abuts against the base plate 42. After the receiving plate 3 is rotated to a vertical position, the adjusting plate 44 pushes the sandwich completely off the side frame 31.

[0035] Before the flip plate 43 rotates, it remains in contact with the side frame 31, thus preventing it from interfering with the entry of the sandwich blank. The bending transition at the end of the flip plate 43 also effectively protects the sandwich. During the rotation of the flip plate 43, the receiving plate 3 also rotates downwards. The sandwich rotates under gravity, and the right-angled edge of the sandwich abuts against the flip plate 43, pushing the sandwich into an upright position with its inclined surface facing the auxiliary conveyor 8, ensuring that the sandwiches maintain a consistent orientation in the upright position. The bending setting of the flip plate 43 and the angle at which the flip plate 43 rotates when the adjusting plate 44 abuts against the base plate 42 ensure that the sandwich is stably pushed onto the auxiliary conveyor 8.

[0036] refer to Figure 3 and Figure 9The tilting assembly 5 includes a tilting cylinder 51, a traction rod 52, a sliding frame 53, and an upper spring 54. The sliding frame 53 is slidably connected to the base frame 1. There are two upper springs 54, which are installed on the base frame 1, and the top of the upper springs 54 is fixedly connected to the bottom of the sliding frame 53. There are two sets of traction rods 52, one set on each side of the sliding frame 53. One end of the traction rod 52 is rotatably connected to the sliding frame 53, and the other end is rotatably connected to the bottom of the receiving plate 3. The upper surface of the sliding frame 53 has protrusions on both sides. When the traction rod 52 abuts against the protrusions on the upper surface of the sliding frame 53, the traction rod 52 lifts the receiving plate 3 to a horizontal position. The tilting cylinder 51 is an electric cylinder, which is vertically installed in the base frame 1. The piston rod is set upward and passes through the sliding frame 53 and is fixedly connected to a pull-down plate 511. When the pull-down plate 511 is not in contact with the sliding frame 53, the sliding frame 53 will move to the horizontal position of the receiving plate 3 under the action of the upper spring 54. The tilting cylinder 51 can drive the sliding frame 53 to move to the vertical position of the receiving plate 3 by means of the piston rod. In this way, the piston rod of the tilting cylinder 51 can effectively improve the stability of the receiving plate 3 in the horizontal position by using the pull-down plate 511 to drive the sliding frame 53 to move downward, and reduce the positional error caused by the extension and retraction of the tilting cylinder 51.

[0037] refer to Figure 10 The material blocking adjustment device 7 includes a top frame 71, an equipment platform 72, a first electric slide 74, a mounting frame 73, a second electric slide 75, a main baffle 76, and a secondary baffle 77.

[0038] A top frame 71 is mounted above the main conveyor 6. An equipment platform 72 is slidably connected to the top frame 71, parallel to the conveying direction of the main conveyor 6. A second electric slide 75 is mounted on the top frame 71, and its slide is fixedly connected to the equipment platform 72 to drive the equipment platform 72 to slide. A first electric slide 74 is vertically mounted on the equipment platform 72, and a mounting frame 73 is mounted on the bottom of the slide of the first electric slide 74. Main baffles 76 are arranged in rows on the mounting frame 73. The number of main baffles 76 is the same as the number of sandwich blanks conveyed in rows on the main conveyor 6, and their positions are opposite. The main baffles 76 are right-angled plates located on the movement path of the sandwich blanks. The opening orientation of the main baffles 76 is the same as the opening orientation of the front baffle 2224. After the sandwich blanks come into contact with the front baffle 2224 on the main conveyor belt, they gradually adhere to the inner wall of the main baffles 76, causing the sandwich blanks to rotate to a state where one diagonal is parallel to the conveying direction of the main conveyor 6. The secondary baffles 77 are also installed in a row on the mounting bracket 73, opposite to the main baffles 76, and closer to the sandwich cutting adjustment unit relative to the main baffles 76. The number of secondary baffles 77 is the same as that of the main baffles 76, the installation height is the same, the opening orientation is opposite to that of the main baffles 76, and the distance between them exceeds the diagonal length of a sandwich prep.

[0039] When the mounting bracket 73 moves to its lowest position, the sandwich blanks on the main conveyor 6 will be intercepted by the main baffle 76.

[0040] Combination Figure 11 Then, the mounting frame 73 will move in the conveying direction of the main conveyor 6 at a speed exceeding the moving direction of the main conveyor 6, and will abut against the sandwich blank in front of it through the auxiliary baffle 77 and move the sandwich blank to the position where it abuts against the front baffle 2224.

[0041] Combination Figure 12 Then, the mounting bracket 73 is moved to a height where the main baffle 76 and the auxiliary baffle 77 will not obstruct the sandwich blank, and then reset. In this way, not only can the position of the sandwich blank on the main conveyor 6 be adjusted, but the sandwich blank can also be stably moved onto the receiving plate 3.

[0042] This application discloses a sandwich cutting and adjusting unit and a sandwich production line. The implementation principle is described using the dynamic operation of the sandwich production line: The sandwich prep is conveyed on the main conveyor 6. After the prep abuts against the main baffle 76, it rotates to a state where it is in contact with the inner wall of the main baffle 76. Subsequently, the second electric slide 75 drives the equipment platform 72 to move backward, causing the auxiliary baffle 77 to push the contacted sandwich prep onto the receiving plate 3 and abut against the front baffle 2224. The first electric slide 74 drives the mounting bracket 73 to move upward, causing the main baffle 76 and the auxiliary baffle 77 to move upward together and reset, thus realizing the position adjustment of the sandwich prep and its movement towards the sandwich cutting and adjusting unit.

[0043] Telescopic cylinder 2 drives cutter 21 to move downward and cut the sandwich blank into two sandwiches. Telescopic cylinder 2 also drives cutter 21 and front baffle 2224 to move upward together. Subsequently, flipping cylinder 51 drives sliding frame 53 to move downward via pull plate 511, causing two receiving plates 3 to rotate downward to a vertical position, standing the sandwich upright on side frame 31. During this process, drive cylinder 41 drives adjusting plate 44 to slide, and drives flipping plate 43 to rotate via drive rod 441. As the sandwich stands upright, it will abut against flipping plate 43 by gravity and maintain an inclined surface facing the auxiliary conveyor 8. Subsequently, drive rod 441 drives base plate 42 to slide via adjusting plate 44, and pushes the sandwich between two partitions in a set within the auxiliary conveyor 8 via flipping plate 43, completing the cutting of the sandwich and the adjustment of its uniform orientation.

[0044] Finally, the sandwiches, maintaining a uniform orientation, move on the auxiliary conveyor 8 to the sandwich packaging equipment for packaging. This design changes the layout of the fully automated sandwich production equipment, reducing the number of conveyors and their length. The sandwiches, cut by multiple conveyors, are now positioned uniformly on the receiving plate 3, improving production efficiency and effectively saving on equipment investment for the sandwich production line.
