[0035] According to the above structural characteristics of the present application, the implementation manners of the present application are further described as follows:

[0036] Refer to Figures 1 to 2 , this embodiment provides a transmission mechanism for a pair-roller steamed bun machine, including a mounting frame 1, an upper forming roller 2, a lower forming roller 3 and a driving module 4; the upper forming roller 2 and the lower forming roller 3 are respectively rotatably arranged in the mounting frame 1; the driving module 4 is respectively connected to the upper forming roller 2 and the lower forming roller 3, and the driving module 4 is used to drive the upper forming roller 2 and the lower forming roller 3 to rotate, so as to complete the conveying and slicing of the dough stream.

[0037] Refer to Figures 1 to 2 , the surface of the upper forming roller 2 is provided with a first spiral groove, and the surface of the lower forming roller 3 is provided with a second spiral groove; the upper forming roller 2 and the lower forming roller 3 rotate in the same direction, and the first spiral groove and the second spiral groove have the same helix direction and are mutually adapted; the upper forming roller 2 and the lower forming roller 3 are arranged in parallel. The first spiral groove and the second spiral groove are used to extrude and convey the dough stream.

[0038] Refer to Figures 1 to 2 , the driving module 4 includes a driving shaft 41 and a transmission gear set, and the transmission gear set includes a driving gear 42, a first intermediate gear 43, an upper roller gear 44, a second intermediate gear 45 and a lower roller gear 46 that are meshed in sequence; the driving shaft 41 is rotatably arranged in the mounting frame 1 and is arranged in parallel with the upper forming roller 2; the driving gear 42 is fixedly installed at the end of the driving shaft 41 (for example, fixedly connected by bolts), the upper roller gear 44 is fixedly installed at the end of the upper forming roller 2 (for example, fixedly connected by bolts), and the lower roller gear 46 is fixedly installed at the end of the lower forming roller 3 (for example, fixedly connected by bolts).

[0039] Refer to Figure 2 , a partition plate 13 (for example, fixedly connected by bolts) is arranged in the mounting frame 1, and the partition plate 13 divides the inner cavity of the mounting frame 1 into a first cavity 131 and a second cavity 132. The upper forming roller 2 and the lower forming roller 3 are arranged in the first cavity 131, and the transmission gear set is arranged in the second cavity 132. The partition plate 13 is used to prevent the flour dust in the first cavity 131 from entering the transmission gear set, so as to protect the stable operation of the transmission gear set.

[0040] The top end of the first spiral groove is fixedly connected with a first spiral fin (for example, through integral fixed connection), and the top end of the second spiral groove is fixedly connected with a second spiral fin (for example, through integral fixed connection); the diameter of the first spiral fin gradually increases in the direction close to the transmission gear set, the diameter of the second spiral fin gradually increases in the direction close to the transmission gear set, and when the first spiral fin and the second spiral fin are in contact with each other, the splitting of the dough blank flow is realized.

[0041] Referring to Figure 2 , one end of the driving shaft 41 far from the transmission gear set is connected with a power source through a coupling 47, and the power source is a driving motor. The outer shell of the driving motor is fixedly connected with the inner wall of the outer shell of the double-roller steamed bun machine through bolts.

[0042] Referring to Figure 2 , since the cleaning of the coupling 47 is relatively difficult, the coupling 47 is arranged outside the installation frame 1 to prevent the flour dust in the first cavity 131 / second cavity 132 from entering the coupling 47, thereby avoiding the problem that the coupling 47 is stuck by flour.

[0043] Referring to Figure 2 And Figure 7 , the driving shaft 41 is arranged above the upper forming roller 2, and the upper forming roller 2 is arranged obliquely above the lower forming roller 3.

[0044] Referring to Figure 1 And Figure 7 , the side wall of the installation frame 1 is provided with a feed inlet 11, a material passing gap is arranged between the upper forming roller 2 and the lower forming roller 3, the feed inlet 11 and the material passing gap are of the same height and communicate with each other. The output port of the dough conveying part is fixedly installed at the position of the feed inlet 11 through bolts, so as to press the dough blank flow into the material passing gap; the outer shell of the dough conveying part is fixedly installed at the position of the inner wall of the outer shell of the double-roller steamed bun machine through bolts. A discharge port 12 is formed on the bottom plate of the installation frame 1, and the discharge port 12 is arranged below the end of the material passing gap. The dough blank blocks obtained by splitting by the upper forming roller 2 and the lower forming roller 3 fall into the discharge port 12 from the end of the material passing gap. Baffle plates are respectively arranged on the left and right sides of the material passing gap to prevent the dough blank flow from falling, and both ends of the baffle plates are fixedly connected with the two side walls of the first cavity 131 through bolts.

[0045] Referring to Figure 2 , both ends of the upper forming roller 2 are respectively installed on the side wall of the first cavity 131 through bearings; both ends of the lower forming roller 3 are respectively installed on the side wall of the first cavity 131 through bearings, and both ends of the driving shaft 41 are respectively installed on the side wall of the first cavity 131 through bearings; the first intermediate gear 43 is installed on the inner wall of the second cavity 132 through a bearing, and the second intermediate gear 45 is installed on the inner wall of the second cavity 132 through a bearing.

[0046] Referring toFigure 3 On the top wall of the first cavity 131, a vertically arranged and detachable brush 5 is installed. Flour dust is inevitably generated in the first cavity 131. If the flour dust adheres to the surface of the driving shaft 41 and is not cleaned in time, it will deteriorate and breed bacteria, leading to food safety accidents. Therefore, the brush 5 is used in time to sweep away the flour dust adhering to the surface of the driving shaft 41 to avoid the occurrence of food safety accidents.

[0047] Refer to Figure 3 And Figure 4 As shown in, the brush 5 includes bristles 51, a mounting plate 52 and a limiting plate 53. The mounting plate 52 and the limiting plate 53 are fixedly connected in a T shape (for example, by integral fixed connection), and the bristles 51 are fixedly installed at the bottom end of the mounting plate 52 (for example, by hot melt fixed connection); the bristles 51 are elastically pressed against the driving shaft 41; a strip hole 14 is formed in the top plate of the mounting frame 1, and the strip hole 14 is adapted to the mounting plate 52. The mounting plate 52 is inserted into the strip hole 14, and the limiting plate 53 is detachably installed on the upper surface of the top plate of the mounting frame 1 through bolts. The user regularly removes the brush 5 for cleaning to remove the flour dust adhering to the bristles 51, further avoiding the occurrence of food safety accidents.

[0048] Refer to Figure 5 As shown in, a door body 15 is installed on the bottom plate of the mounting frame 1; one end of the door body 15 is hinged to the bottom plate, and the other end is connected to the bottom plate through a spring buckle. A door opening is formed in the bottom plate of the mounting frame 1, and the door body 15 is arranged in the door opening. Since the upper forming roller 2 and the lower forming roller 3 inevitably generate dough scraps when cutting the dough blank flow, the dough scraps will fall to the bottom of the first cavity 131. Therefore, the user can open the door body 15 to remove the dough scraps to avoid the occurrence of food safety accidents.

[0049] Different from dry flour dust, the dough scraps have a certain humidity and thus have higher viscosity. Especially after drying, the dough scraps will adhere to the upper surface of the door body 15 and are difficult to remove. Therefore, refer to Figure 5 And Figure 6 As shown in, a detachable fastening plate body 151 is installed on the upper surface of the door body 15, and then the dough scraps will adhere to the upper surface of the fastening plate body 151 after falling; the user opens the door body 15, pulls out the current fastening plate body 151 and inserts a new fastening plate body 151, and then closes the door body 15 to continue the cutting operation, which can quickly remove the dough scraps and avoid the problem of cleaning work taking up working hours. Moreover, since the present utility model is installed in the inner cavity of the pair-roller steamed bun machine and has a small operable space, a slit of the door body 15 can be opened to pull out the fastening plate body 151, avoiding the difficulty of reaching into the mounting frame 1 to clean the upper surface of the door body 15. After the pulled-out fastening plate body 151 is soaked in clean water, the user can more easily brush / remove the dough scraps. After being cleaned with disinfectant water / high-temperature sterilized and dried, it can be recycled.

[0050] Referring to Figure 6 , both ends of the fastening plate body 151 are connected to the door body 15 in a form of elastic clamping. At both ends of the top surface of the door body 15, protrusions for adapting to the clamping of the fastening plate body 151 are respectively provided, so as to ensure that the upper projection of the fastening plate body 151 can completely cover the upper projection of the door body 15, and prevent the dough scraps from falling on the door body 15.

[0051] Referring to Figure 8 , the bottom plate of the installation frame 1 cannot be completely occupied by the door opening because edges need to be left for installing hinges to realize the installation of the door body 15. At the edge position of the fastening plate body 151, an upturned shielding portion 1511 is integrally fixedly connected, which is used to shield the edge of the bottom plate and the hinge, and prevent flour dust from entering the gap of the hinge and causing food safety accidents.

[0052] Referring to Figure 8 , Figure 9 and Figure 10 , an extension opening 121 is provided on the inner side wall of the discharge port 12. The width of the extension opening 121 is smaller than the width of the discharge port 12, and the extension opening 121 is connected to the discharge port 12 in a convex shape; when the shielding portion 1511 is placed above the hinge, the edge of the fastening plate body 151 is directly above the position where the extension opening 121 and the discharge port 12 meet, so as to prevent the fastening plate body 151 from shielding the discharge port 12; a groove is provided on the lower surface of the fastening plate body 151, and a straight array of push plates 1512 (for example, integrally fixedly connected) is fixedly connected in the groove. When the user inserts his hand / tools into the extension opening 121 and / or the discharge port 12, the fastening plate body 151 can be pushed out by the push plates 1512, so that the fastening plate body 151 can be conveniently withdrawn.

[0053] The structure of the present utility model is simple and the function is reliable. The upper forming roller 2 and the lower forming roller 3 that rotate in the same direction can convey and cut the dough blank stream, thereby forming dough blank blocks; the main shaft 41 of the driving module 4 is connected to the power source through a coupling 47 to improve the compatibility of the present utility model and avoid problems such as accelerated wear, reduced stability, and generation of noise caused by low coaxiality. The fastening cover plate can be withdrawn under the condition that the door body 15 is only opened a slit, so as to realize the removal of dough scraps, avoid the problem of cleaning work occupying working hours, and at the same time have less requirements for the working space, be convenient to operate, and be flexible and reliable.
