[0033] Further, the height of upper conveyor 2 relative to lower conveyor 1 is adjustable, so that the utility model can be applicable to sandwich and convey breads of different thicknesses, and the height adjustment mode of upper conveyor 2 can be as follows:

[0034] Example one is as shown in Fig. Figure 1 、 2As shown, both sides of the lower conveyor 1 are fixed with support rods 51, the support rods 51 are screw-connected with lifting nuts 52, both sides of the crossbeam of the upper conveyor 2 are provided with connecting holes, the connecting holes of both sides of the upper conveyor 2 are respectively sleeved outside the two support rods 51, the lifting nuts 52 support the crossbeam of the upper conveyor 2 so that the upper conveyor 2 keeps a fixed height relative to the lower conveyor 1.

[0036] Further referring to the attached Figure 7 and 8 , the slitting knife 3 is fixed between the lower conveyor 1 and the upper conveyor 2, and one end of the slitting knife 3 close to the starting end of the lower conveyor 1 is the blade part 31, so that the bread is cut when passing through the blade part 31 to form the bread slices on the lower conveyor 1 and the bread slices between the slitting knife 3 and the upper conveyor 2. Among them, the bread slices on the lower conveyor 1 are driven to realize conveying by the belt of the lower conveyor 1, and the bread slices between the slitting knife 3 and the upper conveyor 2 are driven to realize conveying by the friction force formed between the belt of the upper conveyor 2 and the bread slices.

[0037] Further, in the above embodiment one, as shown in the attached Figure 3 and4 As shown in the drawings, the connecting seat 53 is fixedly connected to the both sides of the crossbeam of the lower conveyor 1, the connecting rod 33 is fixedly connected to the connecting seat 53, the connecting rod 33 is provided with a notch 651 at the end of the middle of the lower conveyor 1, the both sides of the slitting knife 3 are inserted into the notches 651 of the two connecting rods 33, and then the screws are threaded on the connecting rod 33 to press the slitting knife 3, so as to achieve the suspended fixation of the slitting knife 3.

[0038] As shown in the drawings, the connecting seat 53 is fixedly connected to the both sides of the crossbeam of the lower conveyor 1, the connecting rod 33 is fixedly connected to the connecting seat 53, the connecting rod 33 is provided with a notch 651 at the end of the middle of the lower conveyor 1, the both sides of the slitting knife 3 are inserted into the notches 651 of the two connecting rods 33, and then the screws are threaded on the connecting rod 33 to press the slitting knife 3, so as to achieve the suspended fixation of the slitting knife 3. Figure 5 and 6 As shown in the drawings, the first connecting rod 63 and the second connecting rod 64 have the same length, the connecting pin 65 is provided with a notch 651 at the end of the middle of the lower conveyor 1, the both sides of the slitting knife 3 are respectively sleeved in the notches 651 of the connecting pins 65 of the two lifting mechanisms 6, and then the screws are threaded on the connecting pin 65 to press the slitting knife 3, so as to achieve the suspended fixation of the slitting knife 3. In this structure, no matter how high the upper conveyor 2 is lifted relative to the lower conveyor 1, the connecting pin 65 is always located at the middle position between the upper fixed seat 61 and the lower fixed seat 62, so that while the height of the upper conveyor 2 relative to the lower conveyor 1 is adjusted, the slitting knife 3 is always located at the middle position between the upper conveyor 2 and the lower conveyor 1, without the need for secondary adjustment of the height of the slitting knife 3, and the two bread slices after being cut by the slitting knife 3 can also keep the same thickness.

[0039] Preferably, the supporting plates 71 can be fixed between the two crossbeams of the lower conveyor 1 and the two crossbeams of the upper conveyor 2, so that the conveying belt of the lower conveyor 1 moves on the supporting plate 71, and the supporting plate 71 of the upper conveyor 2 moves under the supporting plate 71, thereby ensuring the clamping and conveying of the bread and the bread slices. Alternatively, a plurality of push plates 72 can be fixed on the surface of the conveying belt of the lower conveyor 1 and the surface of the conveying belt of the upper conveyor 2, and the push plates 72 are distributed at equal intervals. The push plates 72 are moved by the operation of the conveying belt to push the bread or the bread slices, and the push plates 72 of the lower conveyor 1 and the push plates 72 of the upper conveyor 2 keep a gap to avoid the slitting knife 3.

[0040] As shown in the drawings, the connecting seat 53 is fixedly connected to the both sides of the crossbeam of the lower conveyor 1, the connecting rod 33 is fixedly connected to the connecting seat 53, the connecting rod 33 is provided with a notch 651 at the end of the middle of the lower conveyor 1, the both sides of the slitting knife 3 are inserted into the notches 651 of the two connecting rods 33, and then the screws are threaded on the connecting rod 33 to press the slitting knife 3, so as to achieve the suspended fixation of the slitting knife 3. Figures 7 to 10As shown, the conveying surface of the lower conveyor 1 slopes downwards between the inlet and outlet ends to form a transition section 11. The transition section 11 can be formed by installing a transverse roller at the upper end of the lower conveyor 1, with both ends connected to the two crossbeams of the lower conveyor 1. Rollers 13 are connected to both sides of the lower end of the transition section 11, with the height of the two rollers 13 lower than the height of the roller. The conveyor belt passes over the roller, then over the two rollers 13, and then conveys horizontally, thus forming the transition section 11. The upper conveyor 2 is positioned above the transition section 11, thereby widening the distance between the lower conveyor 1 and the slitting blade 3. This allows one end of the feeding conveyor 4 to extend between the slitting blade 3 and the lower conveyor 1, and to be located after the transition section 11, so as to convey the meat floss to the surface of the bread slices conveyed on the lower conveyor 1.

[0041] As attached Figure 11 As shown, the feeding conveyor 4 is a screw conveyor. One end of the screw conveyor is provided with a discharge port 41, which is located between the slitting knife 3 and the lower conveyor 1 and faces downward. The other end of the screw conveyor is a feeding port 42, and the discharge port 41 faces upward. A hopper 43 can be connected to the discharge port 41 to spread meat floss. The meat floss is transported from the feeding port 42 to the discharge port 41 by the screw blades inside the screw conveyor. When the bread slices on the lower conveyor 1 are transported to the feeding conveyor 4, the feeding conveyor 4 transports the meat floss onto the bread slices on the lower conveyor 1.

[0042] Preferably, the present invention may also be configured with a control system and a position sensor. The control system may be a PLC controller, used to control the opening and closing of the lower conveyor 1, the upper conveyor 2 and the screw conveyor. The position sensor is fixed on one side of the crossbeam of the lower conveyor 1, and the position sensor corresponds to the position of the feeding conveyor 4, so that when the bread slice is conveyed on the conveying surface of the lower conveyor 1 and passes the feeding conveyor 4, it can be sensed by the position sensor, and the position sensor sends the sensed signal to the control system, so that the control system controls the lower conveyor 1 and the upper conveyor 2 to stop the conveying of the bread slice, and then controls the feeding conveyor 4 to convey the meat floss to the bread slice located on the lower conveyor 1.

[0043] In addition, guide plates 12 can be installed on both sides of the starting end of the lower conveyor 1. Both guide plates 12 are inclined towards the middle position of the lower conveyor 1 to form a bucket-shaped structure, so that the bread conveyed on the lower conveyor 1 can be kept in the middle of the lower conveyor 1 under the guidance of the two guide plates 12 between the lower conveyor 1 and the upper conveyor 2, so that the bread slices conveyed on the lower conveyor 1 after being cut can be conveyed to the corresponding discharge port 41 of the feeding conveyor 4.

[0044] With the above structure, the working principle of this utility model is as follows:

[0045] The bread is placed on the starting end of the lower conveyor 1 and conveyed so that it is clamped between the lower conveyor 1 and the upper conveyor 2.

[0046] When the bread passes through the blade 31 of the cutter 3, it is cut into two pieces by the blade 31 of the cutter 3, forming a bread slice that is conveyed on the lower conveyor 1 and a bread slice that is conveyed between the cutter 3 and the upper conveyor 2.

[0047] When the bread slices conveyed on the lower conveyor 1 are conveyed to the position of the feeding conveyor 4, the feeding conveyor 4 will extrude the meat floss onto the cross-section of the bread slices;

[0048] When the bread slices on the lower conveyor 1 are conveyed below the slitting knife 3, the bread slices on the slitting knife 3 simultaneously leave the end of the slitting knife 3 away from the blade 31 and fall onto the bread slices conveyed on the lower conveyor 1, thus forming a bread style of meat floss sandwich bread with two bread slices sandwiching meat floss.

[0049] In addition, to prevent the bread slices on the slitting blade 3 from falling due to a large height difference, a transition plate 32 can be connected to one end of the slitting blade 3 near the end point of the lower conveyor 1 (i.e., the end away from the blade 31). The transition plate 32 is inclined downward relative to the slitting blade 3. The bread slices located between the slitting blade 3 and the upper conveyor 2 can then slide down along the guide section to cover the bread slices located on the lower conveyor 1, so that the upper bread slices can smoothly transition to cover the lower bread slices, thereby covering the meat floss. Furthermore, the bottom sides of the transition plate 32 and the bottom sides of the slitting blade 3 are connected by hinges to form a hinge structure, allowing the transition plate 32 to swing relative to the slitting blade 3. Both sides of the transition plate 32 are also connected to swing rods via spherical bearings. Both sides of the crossbeam of the upper conveyor 2 are provided with strip holes 101. The upper end of the swing rod passes through the strip hole 101 and is screwed to the adjusting nut 34. By rotating the adjusting nut 34, the swing rod moves upward or downward through the strip hole 101 to adjust the angle of the transition plate 32 relative to the slitting blade 3, thereby adjusting the angle at which the bread slices conveyed on the slitting blade 3 slide down, and thus adjusting the time of the bread slices sliding down so that the bread slices can correspond to the bread slices conveyed on the lower conveyor 1 after sliding down.

[0050] In summary, in the structure of this utility model, bread is transported between the lower conveyor 1 and the upper conveyor 2 via the lower conveyor 1. The bread is simultaneously conveyed while being held in place by the conveyor belts of both the lower and upper conveyors 1 and 2. This allows the bread to be pushed and cut in half by the slitting blade 3, forming two bread slices, thus preventing the bread from being blocked by the slitting blade 3 and unable to be cut forward. After cutting, the bread slices on the lower conveyor 1 are conveyed to the feeding conveyor 4, where the feeding conveyor 4 extrudes meat floss onto the bread slices. Simultaneously, the bread slices on the lower conveyor 1 exit the slitting blade 3 and fall off, covering the bread slices conveyed on the lower conveyor 1, forming two overlapping bread slices that sandwich the meat floss, creating a meat floss sandwich bread. This process eliminates the need for manual cutting and spreading of meat floss, making it more convenient and significantly reducing labor costs. Furthermore, the continuous conveying by the lower conveyor 1 and the upper conveyor 2 enables the continuous preparation of meat floss-filled bread, which helps increase the yield of meat floss-filled bread.

[0051] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
