[0056] It should be understood that, specifically, the fillings to be injected into the bread can be pumped by a pump, and the pump is connected to the plurality of injection tubes 8 by a shunt pipe, so that the fillings can be pumped;

[0057] During the grouting process, the second motor 14 is started, and the second motor 14 drives the threaded rod 15 to rotate. The threaded rod 15 threads drive the threaded sleeve 16 to move, and the threaded sleeve 16 drives the moving seat 12 to move. The moving seat 12 synchronously drives multiple core injection tubes 8 to move through the plug-in port 6 and enter the shelf cavity 4 until they are inserted into the bread. Then the first motor 10 is started to flip, and the first motor 10 drives the threaded rod 15 to flip, and the threaded rod 15 drives the threaded sleeve 16 to reset, thereby synchronously driving multiple core injection tubes 8 to be pulled out until they are reset.

[0058] Both ends of the bottom of the movable frame 13 are fixedly connected with sliding sleeves 17, and the two sliding sleeves 17 are slidably connected with sliding rails 18. The two sliding rails 18 are fixedly connected to the surface of the supporting frame 11. It should be understood that the sliding connection between the movable frame 13 and the supporting frame 11 is achieved through the cooperation of the sliding rails 18 and the sliding sleeves 17.

[0059] like Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, in one embodiment, between the plurality of limit posts 5 and the first frame 101 are provided:

[0060] A support rod 19, a movable plate 20 is slidably sleeved on the surface of the support rod 19, a connecting frame 21 is fixedly connected to the top of the movable plate 20, and the connecting frame 21 is fixedly sleeved on the surfaces of the plurality of limit columns 5;

Under the reset support of the first supporting spring 22, the movable plate 20 will drive the multiple limit columns 5 to reset through the fixed plate 27, and push the bread close to the flexible retaining ring 7 into the storage cavity 4, so as to avoid the bread from being scratched by the flexible retaining ring 7 during the transportation process, which is conducive to avoiding the scratch damage to the bread during the transportation process.

[0069] When the moving seat 12 drives multiple injection tubes 8 to move and insert into the bread, the third inclined surface 2901 at the bottom end of the hanging plate 29 will be lifted up by the cooperation of the matching block 25 until it passes through. Then, the bottom end of the hanging plate 29 is lowered by the action of the second support spring 30 and supported to a height that can be hung.

In the process of extraction, the bread is driven away from the side baffles 31 and is in a spacious space, which is convenient for later removal.

[0071] like Figure 1 As shown, in one embodiment, a filling process for sandwich bread comprises the following steps.

[0072] Step 1: Loading: Place the bread in the storage chamber 4, and then use the conveyor belt 2 to move the bread in the storage chamber 4 to a position aligned with the limit pin 5;

[0073] Step 2, grouting: After driving a plurality of core injection tubes 8 through the insertion opening 6 of the limiting column 5 by the driving assembly, the plurality of core injection tubes 8 are inserted into the bread in the storage cavity 4, and then the filling is injected into the bread through the core injection tubes 8;

[0074] Step 3, grouting while withdrawing: The core injection tube 8 is retracted by the moving assembly, and the core injection tube 8 will drive the bread to move until it contacts the flexible retaining ring 7 at the end of the upper limit column 5, which limits the bread and helps to avoid damage caused by rigid collision. While the core injection tube 8 continues to move out of the bread, grouting continues until the core injection tube 8 moves to the end of the bread, then the grouting is stopped and the core injection tube 8 is reset to the initial position to complete the core wrapping.

[0075] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.

Step 1: Loading: placing the bread in the storage chamber (4), and then moving the bread in the storage chamber (4) to a position aligned with the upper limit column (5) via the conveyor belt (2); Step 2, grouting: after driving a plurality of core injection tubes (8) through the insertion opening (6) of the limiting column (5) through the driving assembly, the plurality of core injection tubes (8) are inserted into the bread in the storage cavity (4), and then the filling is injected into the bread through the core injection tubes (8); Step 3, grouting and withdrawing at the same time: the core injection tube (8) is driven to be retracted by the moving assembly, and the core injection tube (8) will drive the bread to move until it contacts the flexible retaining ring (7) at the end of the upper limit column (5), which limits the bread and helps to avoid damage caused by rigid collision. In addition, the core injection tube (8) continues to move out of the bread and continues to inject grout until the core injection tube (8) moves to the end of the bread, then stops injecting grout and resets the core injection tube (8) to its initial position.
