Description

Technical Field

[0001] The utility model relates to the technical field of bread production, in particular to a shaping device. Background Art

[0002] In the bread production process, the dough usually needs to be shaped, especially for bagels, which need to be rolled into strips and then rolled into a ring shape. Currently, bagels in many cases are shaped manually, which is very inefficient and the appearance consistency of the formed bagels is poor.

[0003] The technical solution disclosed in the Chinese patent with authorization announcement number CN219515101U uses a conveyor belt to send the dough to the bottom of the strip rolling component and roll it into strips. The fineness of the strip rolling can be adjusted according to needs, and then the strip noodles are rolled forward along the forming center rod through the flip forming component. While rolling, the curled conveyor belt is used to form the strip noodles into a circular bagel, and then the bagel is swept down by a sweeping brush. In addition, the height of the forming center rod can be adjusted according to production needs or the forming center rod of different diameters can be replaced.

[0004] However, the device still has some shortcomings: the device lacks a structure for adjusting the tension of the conveyor belt, and the conveyor belt gradually becomes loose after long-term use, thereby affecting its conveying efficiency. Moreover, under this structure, the fixed-spacing transmission rollers make the replacement of the conveyor belt time-consuming and laborious. Utility Model Content

The motor A is arranged on the shaping box, and the output end of the motor A is connected to the gear, and the gear is meshed with the outer gear ring.

[0012] Preferably, one end of the frame is slidably connected to the movable frame, and the movable frame is a U-shaped frame. Two transmission rollers are rotatably connected to the frame and the movable frame respectively.

[0013] Preferably, the driving assembly includes a motor B, which drives one of the driving rollers to rotate.

[0014] Preferably, the tensioning adjustment member includes a bidirectional screw rod, a slider, a connecting rod and an adapter.

[0024] Embodiment 1

[0025] like Figure 1-Figure 3As shown, a shaping device proposed in the utility model includes a frame 1, an adjusting mechanism, a transmission roller 91, a driving assembly and a tensioning adjusting member 11. The frame 1 is connected to the shaping box 2, and a core shaft 5 is arranged in the shaping channel 201 of the shaping box 2. The adjusting mechanism includes a turntable 3, a hydraulic cylinder 4 and a motor A8. The turntable 3 is arranged on the shaping box 2, and two hydraulic cylinders 4 are symmetrically arranged on the turntable 3, and the output ends of the hydraulic cylinders 4 on both sides are connected to the core shaft 5, and an outer gear ring 6 is arranged on the turntable 3. The motor A8 is arranged on the shaping box 2, and the output end of the motor A8 is connected to the gear 7, and the gear 7 is meshed with the outer gear ring 6. The adjusting mechanism connects the shaping box 2 and the core shaft 5 to adjust the centering of the core shaft 5 in the shaping channel 201. One end of the frame 1 is slidably connected to the movable frame 101, and the movable frame 101 is a U-shaped frame. The two transmission rollers 91 are rotatably connected to the frame 1 and the movable frame 101 respectively. The two sets of transmission rollers 91 are connected by the conveyor belt 9. The upper horizontal end of the conveyor belt 9 passes through the shaping channel 201, and gradually shrinks into a circle along the direction from the feed port of the shaping channel 201 to the discharge port and surrounds the outside of the core shaft 5. The conveyor belt 9 and the core shaft 5 are coaxial in the shaping channel 201, and the output end of the core shaft 5 is provided with a curved section inclined toward the conveyor belt 9. The driving assembly includes but is not limited to the motor B10, and the motor B10 drives one of the transmission rollers 91 to rotate. The tensioning adjustment member 11 includes a bidirectional screw rod 111, a slider 112, a connecting rod 113 and an adapter 114. A sliding rod is provided on the movable frame 101, and the sliding rod is inserted into the frame 1 and slidably connected thereto. The bidirectional screw rod 111 is rotatably connected to the frame 1, and the bidirectional screw rod 111 synchronously passes through the two sliders 112, and the two sliders 112 are respectively spirally connected to the corresponding ends of the bidirectional screw rod 111. The slider 112 is rotatably connected to the connecting rod 113, and the connecting rod 113 is rotatably connected to the transfer seat 114, and both transfer seats 114 are connected to the horizontal end of the movable frame 101. The tension adjustment member 11 is connected to the frame 1 and drives one of the transmission rollers 91 to move away from or close to the frame 1 to adjust the tension state of the conveyor belt 9. The bidirectional screw 111 is coaxially connected to the worm gear 115, and the worm 116 is rotatably set on the frame 1, the worm 116 is meshed and connected with the worm gear 115, and the worm 116 is connected to the crank 117.

[0026] In this embodiment, the surface that has been initially processed into a strip shape is placed on the conveyor belt 9, and the motor B10 is started. The motor B10 drives the conveyor belt 9 to run, and the conveyor belt 9 sends the strip surface into the shaping channel 201. The surface is gradually rounded and sealed under the action of the conveyor belt 9 and the core shaft 5, so that it changes from a strip to a ring-shaped body. Then the surface of the ring body slides from the curved section of the core shaft 5 and falls on the output end of the conveyor belt 9. This structure avoids the deformation caused by the ring body falling directly vertically on the conveyor belt 9. When the symmetry of the ring body is not high, the up and down pitch angles of the core shaft 5 can be adjusted by adjusting the hydraulic cylinders 4 on both sides, and the angle of the core shaft 5 in the horizontal direction can be adjusted by driving the gear 7 through the motor A8 and driving the turntable 3 to rotate through the outer gear ring 6. When the conveyor belt 9 is loose or needs to be replaced and its tightness is adjusted, the crank 117 is turned to drive the worm 116 to rotate, and then the worm 116 drives the worm wheel 115 and the bidirectional screw 111 to rotate. The rotation of the bidirectional screw drives the sliders 112 on both sides to slide, and then the movable frame 101 is moved closer to or away from the frame 1 through the change of the angle of the connecting rod 113, thereby achieving the purpose of adjusting the tension of the conveyor belt 9. In addition, due to the matching structure of the worm wheel, when the conveyor belt 9 is continuously operating and the frame is vibrating, the bidirectional screw 111 will not rotate, thereby allowing the conveyor belt 9 to maintain stable operation.

[0027] Embodiment 2

[0028] like Figure 1 and Figure 4 As shown, a shaping device proposed by the utility model, compared with the first embodiment, has two mounting seats 12 symmetrically arranged on the frame 1, and the mounting seats 12 on both sides are rotatably connected to the same rotating shaft 13, and the rotating shaft 13 is connected to an arc-shaped rubbing board 14, and the arc-shaped rubbing board 14 is located above the feeding end of the conveyor belt 9 and is gap-matched with it. A torsion spring 15 is sleeved on the rotating shaft 13, and one end of the torsion spring 15 abuts against the upper surface of the arc-shaped rubbing board 14 and the other end is inserted into the mounting seat 12.

[0029] In this embodiment, the dough moves with the conveyor belt 9. When it reaches the feeding end of the arc-shaped rubbing board 14, the arc-shaped rubbing board 14 rolls the dough into strips from the edge of the dough. During this process, the feeding end of the arc-shaped rubbing board 14 is gradually raised until the strips are discharged from its discharging side. Then, the arc-shaped rubbing board 14 is reset under the tension of the torsion spring 15. This structure can replace manual work to roll the dough into strips, further saving labor and improving bread production efficiency.

[0030] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
