Description

Technical Field

[0001] This utility model relates to the technical field of dough kneading devices, and more specifically to a dough kneading device for making Chinese layered pastries. Background Technology

[0002] The dough mixing unit is a core piece of equipment in pasta processing, mainly used for the uniform mixing of flour and water, the formation of the gluten network, and the kneading and fermentation of dough. This unit is also called a dough mixer. Currently, there is a commercially available horizontal dough mixer. This horizontal dough mixer includes a frame, with an upward-opening dough mixing tank on one side of the frame. A horizontal stirring shaft and stirring blades are located in the lower middle part of the mixing tank. One end of the stirring shaft extends out of the mixing tank and connects to the stirring motor of the controller. The stirring motor drives the stirring shaft to rotate, thus mixing the dough. To prevent water or flour from splashing out of the mixing tank during mixing, a snap-on lid is installed at the opening of the mixing tank. Each time flour and water are poured out or dough is removed, the lid needs to be manually opened, which is inconvenient. Furthermore, the position of the mixing tank is fixed, meaning the opening is located at a high point on the dough mixer. Moving flour and water to a higher position or removing dough from a higher position is also difficult. Therefore, this structure needs optimization and improvement. Utility Model Content

[0021] Example: See Figures 1 to 4 As shown, a dough-making device for producing Chinese-style layered pastries includes a rectangular base frame 1. Two sets of vertical support frames 2 are fixedly connected to the base frame 1. A dough-making cylinder 3 is installed inside the support frames 2. A control cabinet 9 is fixedly connected to the base frame 1 on one side of the dough-making cylinder 3. A stirring motor is installed inside the control cabinet 9. A stirring shaft 10 is fixedly connected to the stirring motor via a coupling. The stirring shaft 10 is inserted into the dough-making cylinder 3. A stirring blade is inserted and fixedly connected to the stirring shaft 10 inside the dough-making cylinder 3. 3 includes an arc-shaped base plate 31, with an inclined front panel 32 formed at the front end and an inclined rear panel 33 formed at the rear end. Vertical side panels 34 are formed on both sides of the base plate 31, the front panel 32 and the rear panel 33. Hinges 5 are fixedly connected to the side panels 34 at the center of the arc of the base plate 31. The stirring shaft 10 is connected to the hinge bushing 5 through a bearing. The hinge bushing 5 is connected to the rectangular hinge seat 6 through a bearing. The hinge seat 6 is fixedly connected to the support frame 2.

[0022] The kneading cylinder 3 is provided with a cylinder cover 4 covering the opening of the kneading cylinder 3. The upper sides of the front panel 32, the rear panel 33, and the side panel 34 respectively abut against the cylinder cover 4. The cylinder cover 4 includes a horizontal front cover plate 41, an arc-shaped transition cover plate 42 formed on the rear side of the front cover plate 41, an inclined rear cover plate 44 formed on the rear side of the transition cover plate 42, and side baffles 43 formed on both sides of the rear cover plate 44, the transition cover plate 42, and the front cover plate 41 respectively. The side baffles 43 are respectively fixed on two sets of support frames 2. The kneading cylinder 3 is provided with a flip adjustment device 7 in the middle of its outer bottom surface.

[0023] The flipping adjustment device 7 includes a longitudinal screw 71 located below the kneading cylinder 3. The front and rear ends of the screw 71 are connected to bearing seats 74 via bearings. The bearing seats 74 are fixed to the front and rear side frames of the bottom beam frame 1, respectively. A transverse slider 72 is screwed to the front of the screw 71. An inclined traction rod 73 is abutted on both sides of the slider 72. An inclined guide groove 731 is formed on the traction rod 73. Guide support shafts 721 are formed at both ends of the slider 72. The guide support shafts 721 are inserted into the guide grooves 731 of the traction rod 73, respectively. A handwheel 75 is fixedly connected to the rear end of the screw 71 extending out of the bearing seat 74.

[0024] The support frame 2 includes a U-shaped main support frame 21, the lower end of which is fixed to the bottom beam frame 1. A longitudinal support beam 22 is fixedly connected inside the main support frame 21. The hinged seat 6 is inserted and fixed between the main support frame 21 and the longitudinal support beam 22. Figure 1 As shown, the upper and lower end faces of the hinge seat 6 can be connected to the main support frame 21 and the longitudinal support beam 22 respectively, thereby improving the support strength of the hinge seat 6.

[0025] A transverse buffer roller sleeve 12 is abutted against the rear panel 33 of the dough mixing cylinder 3. A support roller 11 is inserted into the buffer roller sleeve 12. The two ends of the support roller 11 are respectively fixed to the main support frame 21. The support roller 11 can provide the support strength of the main support frame 21. The buffer roller sleeve 12 can reduce the collision deformation when the dough mixing cylinder 3 is closed.

[0026] The upper surface of the side panel 34 is composed of a horizontal surface on the front side and an arc-shaped surface on the rear side. The arc center of the transition cover plate 42 on the cylinder cover 4 and the arc center of the bottom plate 31 on the dough mixing cylinder 3 are both located on the central axis of the stirring shaft 10, thereby achieving effective sealing during dough mixing.

[0027] The diameter of the guide shaft 721 on the slider 72 is equal to the width of the guide groove 731 on the traction rod 73.

[0028] Locking components 8 are fixedly connected to the dough mixing cylinders 3 on both sides of the flipping adjustment device 7. The locking components 8 include L-shaped positioning blocks 81, which are fixedly connected to the inner wall of the front side of the main support frame 21. A horizontal locking bolt 82 is screwed to the rear side of the 81. The locking components 8 are used to effectively lock the dough mixing cylinder 3 when the lid is closed, which can effectively prevent leakage during dough mixing.

[0029] The bottom plate 31 of the dough mixing cylinder 3 is fixed with obliquely placed positioning rods 83 on both sides. Positioning slots 831 are formed on the positioning rods 83. The ends of the locking bolts 82 extend out of the positioning blocks 81 and are respectively inserted into the positioning slots 831 of the positioning rods 83.

[0030] The center distance from the bottom end of the traction rod 73 or the bottom end of the positioning rod 83 to the stirring shaft 10 is less than the center distance from the lower end face of the bottom beam frame 1 to the stirring shaft 10, so there will be no interference with the ground during the flipping of the dough cylinder 3.

[0031] Working principle: This structure is a dough-kneading device for making Chinese-style layered pastries. Its main technical features are the movable dough-kneading bowl 3 and the fixed bowl lid 4, such as... Figure 1 As shown, the cylinder head 4 covers the dough kneading cylinder 3, which is the state when the dough is being kneaded inside the dough kneading cylinder 3;

[0032] When the locking bolt 82 disengages from the positioning rod 83, the slider 73 is driven to move backward by manually rotating the handwheel 75. This causes the dough mixing cylinder 3 to rotate forward around the stirring shaft 10. The front part of the dough mixing cylinder 3 extends out of the cylinder cover 4, and the front panel 32 of the dough mixing cylinder 3 extends out of the cylinder cover 4, but the rear panel 33 remains inside the cylinder cover 4. This allows part of the cylinder opening to move downward and open, allowing flour and water to be poured into the dough mixing cylinder 3. During the pouring process, the cylinder cover 4 also provides protection. Compared to a fully open cylinder opening, this effectively reduces the impact of flour spilling out and water splashing onto the dough mixing cylinder 3. At the same time, the downward movement of the cylinder opening reduces the height at which flour and water are lifted, making it much more convenient.

[0033] When the dough is kneaded, the kneading cylinder 3 is rotated and detached from the cylinder cover 4 by rotating the handwheel 75, so that the front panel 32 of the kneading cylinder 3 is tilted downwards. The front panel 32 is used as a sliding plate to facilitate the removal of the dough.

[0034] The embodiments described above are illustrative of the present invention and are not intended to limit the present invention. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be as set forth in the claims.
