Description

Technical Field

[0001] The present application relates to the technical field of baked food production, and in particular to a wheel knife for bread shaping. Background Art

[0002] During the production process of baked goods, some puff pastry breads are chosen to be made. This is because this type of bread has the product characteristics of a good crispy and soft taste, and a unique puff pastry opening process. The multi-layer folding puff pastry opening technique is used to ensure the crispy and layered taste.

[0003] In the prior art, the crispy bread is conveyed to a bread forming machine through a conveyor belt to determine the shape and size, and then conveyed to an oven through a conveyor belt for baking. During baking, the gas in the bubbles inside the bread will keep the bread in an expanded state due to the high temperature. When it is cooled after baking, the gas will shrink as the temperature drops, which is what we often call thermal expansion and contraction. The bread crust will leave some wrinkles due to the reduction in volume, which has a great impact on the sensory perception of the product, such as Figure 4 As shown, further improvement is needed. Utility Model Content

[0004] In order to reduce the generation of wrinkles on the bread crust, the present application provides a wheel knife for bread shaping.

[0005] The present application provides a wheel cutter for bread forming, which adopts the following technical solution:

[0006] A wheel cutter for bread shaping comprises a mounting bracket mounted on a conveyor belt and a cutting knife assembly rotatably connected to the mounting bracket, the cutting knife assembly comprising a knife seat rotatably connected to the mounting bracket and a blade arranged on the knife seat, the distance between the blade and the conveyor belt is smaller than the height of the bread, and a plurality of blades are arranged at intervals along the axial direction of the knife seat.

[0007] By adopting the above technical solution, since the blade holder is rotatably connected to the mounting bracket, and since the gap between the blade and the conveyor belt is smaller than the height of the bread, the blade can be pressed against the surface layer of the bread to cut the bread. As the conveyor belt is conveyed, the bread drives the blade to rotate, so that each blade cuts the surface layer of the bread in turn, which is conducive to the discharge of water vapor inside the bread during baking, so as to reduce the possibility of water vapor not being able to be discharged and concentrating on the surface of the product during cooling, causing wrinkles on the surface of the bread. And the rotation is driven by the transmission inertia, which reduces the problem of excessive cutting of the bread surface layer by the blade and scratching of the surface appearance due to motor transmission.

[0008] Preferably, it also includes a knife shaft passing through the knife seat, the length direction of the knife shaft is parallel to the width direction of the conveyor belt, the knife shaft is rotatably connected to the mounting bracket, and a plurality of knife cutting assemblies are spaced apart along the length direction of the knife shaft.

[0013] By adopting the above technical solution, when the knife seat slides to the corresponding position according to the position of the semi-finished product panel on the conveyor belt, the fixing bolt is passed through the sliding sleeve and threadedly connected with the second threaded hole to install the knife assembly on the knife shaft, so that when the conveyor belt is transported, the semi-finished bread can be cut with the conveying movement of the conveyor belt.

[0014] Preferably, the mounting bracket includes two mounting plates respectively arranged on both sides of the conveyor belt and a mounting member for detachably connecting the mounting plates to the conveyor belt, and the knife shaft is rotatably connected to the upper end of the mounting plates.

[0015] By adopting the above technical solution, as the use cycle increases, the cutting knife on the knife seat may be damaged. Therefore, the mounting plate is detachably connected to the conveyor belt through the mounting piece to facilitate disassembly and replacement.

[0016] Preferably, the mounting member includes a mounting bolt, a through hole for the mounting bolt to pass through is formed at the lower end of the mounting plate, and first threaded holes for threaded connection of the mounting bolt are formed at both sides of the conveyor belt.

[0017] By adopting the above technical solution, the mounting plate is fastened to the conveyor belt through the cooperation between the mounting bolt and the first threaded hole, and the cutting assembly is installed on the conveyor belt to cut the semi-finished bread. The installation method is relatively simple and the fixing effect is relatively good.

[0018] Preferably, the through holes are arranged in the form of waist-shaped holes along the length direction of the mounting plate.

[0019] By adopting the above technical solution, the perforations are arranged in the shape of waist holes along the length direction of the mounting plate, so that the distance between the blade in the scoring assembly and the conveyor belt can be adjusted according to the needs, so as to adjust the depth of scoring required on the semi-finished bread on the conveyor belt.

[0020] Preferably, one of the blade cutting assemblies comprises two blade seats, and a plurality of the blades are installed between the two blade seats.

[0021] By adopting the above technical solution, a knife cutting assembly includes two knife seats, and a plurality of blades are installed between the two knife seats to improve the installation effect of the blade, reduce the possibility of deflection caused by the reverse force when cutting semi-finished bread, and provide a certain protective effect on both sides of the blade, reducing the possibility of scratches caused by accidental contact with the blade.

[0022] Preferably, the blade is exposed from the blade seat.

[0023] By adopting the above technical solution, the blade is exposed on the blade holder to reduce the possibility of direct contact between the blade holder and the semi-finished bread on the conveyor belt, thereby affecting the appearance of the surface of the semi-finished bread.

[0024] In summary, the utility model has the following beneficial effects:

[0025] Since the blade holder is rotatably connected to the mounting bracket, and since the gap between the blade and the conveyor belt is smaller than the height of the bread, the blade can be pressed against the surface layer of the bread to cut the bread. As the conveyor belt is conveyed, the bread drives the blade to rotate, so that each blade cuts the surface layer of the bread in turn, which is conducive to the discharge of water vapor inside the bread during baking, so as to reduce the possibility of water vapor not being discharged and concentrating on the surface of the product during cooling, causing wrinkles on the surface of the bread. And the rotation is driven by the transmission inertia, which reduces the problem of excessive cutting of the bread surface layer by the blade and scratching of the surface due to motor transmission.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-5 , further details of this application are given.

[0033] The embodiment of the present application discloses a wheel cutter for forming bread.

[0034] Example:

[0035] A wheel knife for bread shaping, referring to Figure 1 , Figure 2 , including a mounting bracket 2 for mounting on a conveyor belt 1, a knife shaft 3 rotatably connected to the mounting bracket 2, and a knife cutting assembly 4 arranged on the knife shaft 3.

[0036] The mounting bracket 2 specifically includes two mounting plates 21 respectively arranged on both sides of the conveyor belt 1 and a mounting member 22 for detachably connecting the mounting plates 21 to the conveyor belt 1. The two mounting plates 21 are respectively in contact with the two side walls of the conveyor belt 1. The mounting member 22 is arranged at the lower end of the mounting plate 21. In this embodiment, the mounting member 22 includes a mounting bolt. A through hole 211 for the mounting bolt to pass through is provided at the lower end of the mounting plate 21. The first threaded hole 11 for the mounting bolt to be threadedly connected is provided on both sides of the conveyor belt 1. In this embodiment, the mounting member 22 may also include an anti-skid pad (not shown in the figure) sleeved on the mounting bolt, which is added according to the needs to reduce the possibility of the mounting plate 21 rotating along the axis of the mounting bolt. Since the anti-skid pad is a prior art, it will not be described in detail here.

[0037] It should be noted that a number of perforations 211 may be arranged at intervals along the length direction of the mounting plate 21, or may be arranged in the form of waist-shaped holes along the length direction of the mounting plate 21. The height position of the highest point of the mounting plate 21 may be adjusted as needed, that is, the height position of the cutting knife assembly 4 may be adjusted to adjust the distance between the cutting knife assembly 4 and the conveyor belt 1. In the present embodiment, the perforations 211 are selected to be arranged in the form of waist-shaped holes along the length direction of the mounting plate 21 to increase the adjustment range of the mounting plate 21.

[0038] The knife shaft 3 is disposed between the two mounting plates 21 , the length direction of the knife shaft 3 is parallel to the width direction of the conveyor belt 1 , and both ends of the knife shaft 3 are rotatably connected to the upper ends of the two mounting plates 21 .

[0039] Reference Figure 1 , Figure 3 , wherein a plurality of blade assemblies 4 are arranged at intervals along the length direction of the blade shaft 3. In this embodiment, two blade assemblies are specifically arranged. The blade assemblies 4 specifically include two sliding sleeves 5 arranged on the blade seat 41 of the blade shaft 3, a fixed sleeve 42 arranged between the two blade seats 41, and a plurality of blades 43 arranged on the fixed sleeve 42. In this embodiment, the blade seat 41 is specifically arranged in a disc, and the blade shaft 3 is arranged coaxially with the blade shaft 3. It should be noted that one blade assemblies 4 includes two blade seats 41, the fixed sleeve 42 is fixedly connected to the two fixed sleeves 42 by bolts, and the fixed sleeve 42 is arranged coaxially with the blade seat 41. A plurality of blades 43 are arranged at intervals along the axis of the fixed sleeve 42 and are fixedly connected to the outer peripheral wall of the fixed sleeve 42. The two ends of the blade 43 are fixedly connected to the surfaces of the two blade seats 41 close to each other, and the blade 43 is partially exposed from the blade seat 41 to reduce the possibility of direct contact between the blade seat 41 and the semi-finished bread on the conveyor belt 1, so as to affect the appearance of the semi-finished bread surface.

[0040] It should be noted that, in the present embodiment, the distance between the blade 43 at the bottom of the blade holder 41 and the upper surface of the conveyor belt 1 is smaller than the height of the bread, so that along with the conveyor belt 1, the bread drives the blade 43 to rotate, so that each blade 43 cuts the surface layer of the bread in turn, which is beneficial to the discharge of water vapor inside the bread during baking, so as to reduce the possibility of water vapor being unable to be discharged and concentrated on the surface of the product during cooling, causing wrinkles on the bread surface.

[0041] Regarding the installation between the tool holder 41 and the tool shaft 3, the tool shaft 3 is provided with a fixing part 31 for limiting the sliding of the tool holder 41, and the fixing part 31 includes a fixing bolt. The tool shaft 3 is provided with a second threaded hole 32 for threaded connection of the fixing bolt, and a plurality of second threaded holes 32 are arranged at intervals along the length direction of the tool shaft 3. The tool holder 41 is protrudingly provided with a sliding sleeve 5, and the sliding sleeve 5 is arranged on the outer surface of the tool shaft 3 and is coaxially arranged. The fixing bolt is slidably penetrated through the sliding sleeve 5 to limit the sliding of the tool holder 41 while allowing the tool holder 41 and the tool shaft 3 to rotate coaxially.

[0042] The implementation principle of the wheel knife for bread forming in the embodiment of the present application is as follows: since the knife seat 41 is fixed on the knife shaft 3, the knife shaft 3 is rotatably connected to the mounting plate 21, and since the gap between the blade 43 and the conveyor belt 1 is smaller than the height of the bread, the blade 43 can be pressed against the surface layer of the bread to cut. With the conveying action of the conveyor belt 1, the bread drives the blade 43 to rotate, so that each blade 43 cuts the surface layer of the bread in turn, which is beneficial to the discharge of water vapor inside the bread during baking, so as to reduce the possibility that water vapor cannot be discharged and is concentrated on the surface of the product during cooling, causing wrinkles on the surface of the bread. The finished bread after cutting is as follows: Figure 5 shown.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
