Description

Technical Field

[0001] The utility model relates to a food blank conveyor belt regulating mechanism, belonging to the technical field of food processing machinery. Background Art

[0002] The applicant's prior patent application CN111053271A provides a food forming method and forming mechanism, wherein the flanging mechanism flanging the food blank causes it to fall onto the conveyor belt below, and is then sent to the downstream folding and rotary forming component station via the conveyor belt. In actual use, the applicant found that due to the long travel of the conveyor belt, a slight angle error when installing the equipment would result in a large offset at the end of the conveyor belt, affecting the folding and rotary forming component's acceptance of the food blank and subsequent forming operations. Since the conveyor belt is composed of three substantially parallel belt bodies, and the ends of the belt bodies on both sides are not flush with the ends of the belt body in the middle, the belt bodies on both sides need to extend an additional distance downstream, which makes the angle adjustment of the conveyor belt very inconvenient. Utility Model Content

[0003] Therefore, the purpose of the utility model is to provide a food material conveyor belt adjustment mechanism that is easy to adjust.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a food blank conveyor belt adjustment mechanism, including a conveyor belt composed of three belt bodies, wherein the length of the belt bodies on both sides extending downstream exceeds the length of the middle belt body extending downstream; the middle belt body passes around an adjustment roller at its farthest end extending downstream, and fixed brackets are provided on both sides of the adjustment roller, and the adjustment roller is installed on a roller shaft, and the adjustment roller and the roller shaft can rotate freely relative to each other and can move axially synchronously; the two ends of the roller shaft respectively pass through the through holes on the fixed brackets on both sides; the two side ends of the roller shaft are provided with screw parts, and the screw parts are provided with adjustment nuts, and the adjustment nuts can be pressed against the fixed brackets.

[0005] An axial limiting structure that cooperates with each other is arranged between the adjusting roller and the intermediate belt body, and the axial limiting structure is used to limit the axial relative displacement between the adjusting roller and the intermediate belt body.

[0006] The axial limiting structure includes at least one annular groove arranged on the side wall of the adjusting roller and at least one convex ridge arranged on the intermediate belt body, and the convex ridge extends along the long direction of the intermediate belt body and enters the annular groove.

[0007] There is one annular groove, which is arranged in the middle of the adjusting roller.

[0008] The adjusting nut is located on a side of the fixing bracket away from the adjusting roller.

[0009] The adjusting nut comprises an internal threaded barrel portion and a screwing portion located on the internal threaded barrel portion.

[0010] An anti-slip structure is arranged on the screwing portion.

[0011] The adjusting roller is mounted on the roller shaft through a bearing.

[0012] By adopting the above technical scheme, the food dough conveyor belt adjustment mechanism of the utility model can adjust only the middle belt body that bears most of the weight of the food dough without adjusting the three belt bodies as a whole, and the structure of the adjustment mechanism is relatively simple. By adjusting the axial position of the adjustment roller, the middle belt body can be fine-tuned left and right, and the operation is also very convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention is further described in detail below through the accompanying drawings and specific implementation methods.

[0018] like Figure 1-4 As shown, the utility model provides a food material conveyor belt adjustment mechanism, including a conveyor belt 1 composed of three belt bodies, an adjustment roller 2, a fixed bracket 3 and an adjustment nut 4. The length of the belt bodies 1a on both sides of the three belt bodies extending downstream exceeds the length of the middle belt body 1b extending downstream. The middle belt body 1b bypasses the adjustment roller 2 at its farthest end extending downstream, and the fixed bracket 3 is arranged on both sides of the adjustment roller 2. The adjustment roller 2 is installed on a roller shaft 5 through a bearing, and the adjustment roller 2 and the roller shaft 5 can rotate freely relative to each other and can move axially synchronously. The two ends of the roller shaft 5 respectively pass through the through holes 31 on the fixed brackets 3 on both sides. Screw parts 51 are arranged on the two side ends of the roller shaft 5, and the adjustment nuts 4 are arranged on the screw parts 51, and the adjustment nuts 4 can be pressed against the fixed brackets 3.

[0019] In this embodiment, the adjusting nut 4 is located on the side of the fixed bracket 3 away from the adjusting roller 2. The adjusting nut 4 includes an internal threaded barrel 41 and a screwing portion 42 located on the internal threaded barrel 41. An anti-slip structure is provided on the screwing portion 42. The axial position of the adjusting roller 2 is adjusted by screwing the left and right adjusting nuts 4, and the axial position of the adjusting roller 2 is locked when the two adjusting nuts 4 are pressed against the outer wall of the fixed bracket 3. Of course, in other embodiments, each of the adjusting nuts 4 can also be provided on the side of the fixed bracket 3 close to the adjusting roller 2, so as to press the fixed bracket 3 from this side for locking.

[0020] An axial limiting structure that cooperates with each other is provided between the adjusting roller 2 and the intermediate belt body 1b, and the axial limiting structure is used to limit the axial relative displacement between the adjusting roller 2 and the intermediate belt body 1b. In this embodiment, the axial limiting structure includes an annular groove 21 provided on the side wall of the adjusting roller 2 and a convex rib 1b1 provided on the intermediate belt body 1b, and the convex rib 1b1 extends along the long direction of the intermediate belt body 1b and enters the annular groove 21. The annular groove 21 is provided in the middle of the adjusting roller 2. In other embodiments, the axial limiting structure can also be a friction surface structure that cooperates with each other.

[0021] Since the three belt bodies have different functions in the conveying process, the middle belt body 1b bears most of the weight of the coating skin and the weight of all the fillings in the food blank 100, and the belt bodies 1a on both sides bear the weight of the edge of the coating skin in the food blank 100, so it is sufficient to fine-tune the angle of the middle belt body 1b. Therefore, by adopting the above technical solution, it is possible to adjust only the middle belt body 1b that bears most of the weight of the food blank without adjusting the three belt bodies as a whole, and the structure of the adjustment mechanism is relatively simple, and the middle belt body 1b is driven to be fine-tuned left and right by adjusting the axial position of the adjustment roller 2, and the operation is also very convenient.

[0022] Obviously, the above embodiments are only examples for clear explanation, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention of the utility model.
