Moreover, due to assembly error, the electric push rod is difficult to assemble at the center position of the U-shaped frame, which further aggravates the unbalanced stress of the U-shaped frame. In addition, due to the assembly gap between the guide rod and the installation plate, the U-shaped frame cannot be lifted vertically, so that the U-shaped frame and the rotating roller may be skewed, unstable, vibrated and noisy during the lifting process, which affects the health of the operator.

Detailed Implementation

[0034] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0035] like Figures 1 to 6 As shown, this utility model provides a flipping device for food processing, including a support 1, a cylindrical rotating frame 2, an upper conveying mechanism 3, and a lower conveying mechanism 4. The cylindrical rotating frame 2 is rotatably mounted on the support 1 around its horizontal axis. The upper conveying mechanism 3 and the lower conveying mechanism 4 are both vertically mounted within the cylindrical rotating frame 2. It also includes an upper synchronous lifting mechanism 5 that moves synchronously with the upper conveying mechanism 3 and a lower synchronous lifting mechanism 6 that moves synchronously with the lower conveying mechanism 4. The lower synchronous lifting mechanism 6 has the same structure as the upper synchronous lifting mechanism 5. The upper synchronous lifting mechanism 5 is rectangular and centrally located at the top of the upper conveying mechanism 3, including four lifting units located at the corners of the rectangle. Each lifting unit includes a lifting rod 55 vertically mounted at the top of the upper conveying mechanism 3, two racks 51 perpendicular to each other and mounted along the axial direction of the lifting rod 55, and two gears 52 rotatably mounted at the top of the cylindrical rotating frame 2 and meshing with the two racks 51 respectively. The two gears 52 arranged parallel to each other on adjacent lifting units are connected by a rotating shaft 53.

[0036] In this food processing flipping device, during operation, firstly, the lower conveying mechanism 4 drives the food forward. When the food reaches a set position, the lower conveying mechanism 4 stops moving. Secondly, the upper conveying mechanism 3 moves downward to cooperate with the lower conveying mechanism 4 to clamp the food. Simultaneously, the upper conveying mechanism 3 also drives the racks 51 and gears 52 on the four lifting units to mesh. Then, the cylindrical rotating frame 2 drives the upper conveying mechanism 3 and the lower conveying mechanism 4 to rotate 180 degrees, causing the food to flip. The flipped food is then output from the flipping device. Subsequent food continues to be conveyed to the lower conveying mechanism 4, repeating the above process to achieve continuous food flipping.

[0037] In the food processing flipping device of this utility model, since the four lifting units are connected by a rotating shaft 53, during the lifting process of the upper conveying mechanism 3 or the lower conveying mechanism 4, the four lifting units can be driven to move synchronously and extend and retract, realizing the meshing transmission of the rack 51 and the gear 52. Since there is no gap when the rack 51 and the gear 52 mesh, "rigid" transmission can be achieved. Even if there is uneven force on the conveying mechanism, it can be ensured that there will be no skew when the conveying mechanism is lifted and lowered, and the movement is relatively smooth, reducing vibration and noise during the movement.

[0038] The upper conveying mechanism 3 and the lower conveying mechanism 4 in the above embodiment can be a belt conveyor, a roller conveyor, etc., and can be selected according to the material, shape, size, etc. of the food. For example, a belt conveyor can be used to convey bread, cakes, etc.

[0039] As shown in Figures 2 to 4 The cylindrical rotating frame 2 also includes a rectangular upper support frame 23 and a lower support frame at the top and bottom thereof, respectively. The upper support frame 23 is provided with an upper lifting cylinder 75 for driving the upper conveying mechanism 3 to move. The lower support frame is provided with a lower lifting cylinder for driving the lower conveying mechanism 4 to move. Four lifting units are respectively arranged at the four corners of the upper support frame 23. Specifically, the upper conveying mechanism 3 and the lower conveying mechanism 4 are each provided with a support plate, and the end of the output shaft of the upper lifting cylinder 75 and the lower lifting cylinder is mounted on the corresponding support plate.

[0040] In the embodiment, the upper lifting cylinder 75 and the four lifting units of the upper synchronous lifting mechanism 5 are arranged on the upper support frame 23, so that the upper lifting cylinder 75 and the upper synchronous lifting mechanism 5 form an integral whole, and the upper synchronous lifting mechanism 5 also realizes synchronous lifting while the upper lifting cylinder 75 extends and retracts, so that the synchronization is better, and the movement of the upper conveying mechanism 3 is more stable.

[0041] As shown in Figure 4 The end of the output shaft of the upper lifting cylinder 75 and the lower lifting cylinder is provided with a floating joint 76. In the embodiment, the upper lifting cylinder 75 drives the upper conveying mechanism 3 to lift through the floating joint 76, and since the floating joint 76 allows a certain rotation angle between the two connected parts, it can reduce assembly errors, protect the upper lifting cylinder 75 and the lower lifting cylinder, maintain the stable operation of the upper conveying mechanism 3 and the lower conveying mechanism 4, and prolong the service life.

[0042] In some embodiments, the upper synchronous lifting mechanism 5 is provided, so that the upper conveying mechanism 3 can be driven by only one upper lifting cylinder 75, that is, the stability of the movement of the upper conveying mechanism 3 is ensured. In this way, the structure is more stable, the installation requirement is lower, and a guide pillar and a sliding block structure can be provided on the upper conveying mechanism 3 and the cylindrical rotating frame 2, which can protect the upper lifting cylinder 75 and prolong the service life of the device. The use of two upper lifting cylinders 75 is not easy to synchronize, and problems are likely to occur during lifting. Therefore, preferably, one upper lifting cylinder 75 and the upper synchronous lifting mechanism 5 are used in cooperation to realize the lifting of the upper conveying mechanism 3. Of course, the lower conveying mechanism 4 also uses the same mechanism for lifting, which will not be described herein. The upper lifting cylinder 75 in the embodiment can also be replaced by an electric cylinder.

[0043] As shown in Figures 4 to 6As shown in the drawings, the lifting rod 55 and the two racks 51 of each lifting unit are integrally formed, so that the connection strength is high and the quality is good. For example, straight tooth grooves along the length direction can be machined on the outer wall of a cylindrical rod to form the lifting rod 55 and the rack 51 in the above embodiment.

[0044] As shown in the drawings, Figures 4 to 6 Each lifting unit further includes a mounting box 54 arranged at the top of the cylindrical rotating frame 2, the gear 52 is arranged to rotate in the mounting box 54, and the rack 51 penetrates the mounting box 54 in the vertical direction. By arranging the mounting box 54, not only is the mounting of the gear 52 facilitated, but also the noise generated when the gear 52 and the rack 51 mesh is reduced.

[0045] As shown in the drawings, Figure 2 and Figure 3 The cylindrical rotating frame 2 includes two rotating rings 21 and a connecting column 22 connecting the two rotating rings 21. The bottom of the support 1 is provided with a driving motor 71, and a transmission shaft is connected to the output shaft of the driving motor 71. Two transmission wheels 72 are sleeved on the transmission shaft. Each transmission wheel 72 is drivingly connected to the corresponding rotating ring 21 through a transmission belt 73. The transmission belt 73 is an open synchronous belt, the transmission wheel 72 is a synchronous pulley, and the rotating ring 21 is provided with synchronous teeth. Two tensioning mechanisms 74 are arranged on each rotating ring 21, and the two tensioning mechanisms 74 are respectively connected to the two ends of the open synchronous belt for adjusting the tightness of the open synchronous belt.

[0046] In this embodiment, the driving motor 71 drives the transmission shaft to rotate, driving the two transmission wheels 72 to rotate, and the transmission wheels 72 drive the two rotating rings 21 to rotate through the transmission belts 73, thereby realizing the rotation of the cylindrical rotating frame 2. Due to the arrangement of the two transmission wheels 72, the two transmission belts 73 and the two rotating rings 21, the force on the cylindrical rotating frame 2 is more uniform, and the rotation is more stable.

[0047] Moreover, since the transmission belt 73 is an open synchronous belt, the tightness of the open synchronous belt can be conveniently adjusted by the tensioning mechanism 74. The open synchronous belt is used in cooperation with the synchronous pulley, so that the transmission is accurate without relative sliding, the transmission efficiency is high, and the noise is low.

[0048] As shown in the drawings, Figure 2 and Figure 3 The tensioning mechanism 74 includes a U-shaped clamp plate 741 for clamping the end of the open synchronous belt, a stud 742 connecting the closed end of the U-shaped clamp plate 741, and two nuts 743 cooperating with the stud 742. The rotating ring 21 is provided with a mounting plate having a mounting hole. The stud 742 penetrates into the mounting hole, and the two nuts 743 abut against the two sides of the mounting plate. A bolt is also penetrated through the U-shaped clamp plate 741, and in use, the bolt is loosened, one end of the open synchronous belt is penetrated into the U-shaped clamp plate 741, and then the bolt is tightened to clamp the open synchronous belt.

[0049] In the embodiment, when adjusting the tightness of the open synchronous belt, the nut 743 close to the U-shaped clamping plate 741 is loosened, and then the nut 743 on the other side is adjusted. Since the nut 743 abuts against the mounting plate, the stud 742 moves under the action of rotation of the nut 743, driving the U-shaped clamping plate 741 to move, thereby tightening or loosening the open synchronous belt. After adjustment, the nut 743 close to the U-shaped clamping plate 741 is tightened to abut against the mounting plate, realizing the operation of adjusting the tightness of the open synchronous belt.

[0050] As shown in Figure 1 The support 1 includes a base frame 11, a cage 12 arranged on the top of the base frame 11, and a rotating wheel 13 arranged at each corner of the base frame 11. Each rotating ring 21 is arranged on two rotating wheels 13.

[0051] In the embodiment, the four rotating wheels 13 are arranged to enable the cylindrical rotating frame 2 to rotate, reducing the resistance in the rotating process and making the rotation smoother. The cage 12 serves a protective function, ensuring the safety of the operator.

[0052] As shown in Figure 2 and Figure 3 The support 1 is provided with a buffer mechanism 77 on both sides. The buffer mechanism 77 includes a buffer cylinder 771, a buffer column 772, a buffer sleeve 773, and a spring 774. The buffer cylinder 771 is arranged vertically on the support 1, the buffer column 772 is arranged in the buffer cylinder 771 and moves along the axis of the buffer cylinder 771, and the upper end of the buffer column 772 is provided with the buffer sleeve 773. The spring 774 is sleeved on the buffer column 772, and the two ends abut against the end face of the buffer sleeve 773 and the buffer cylinder 771, respectively. The cylindrical rotating frame 2 is provided with a stop plate 24 that stops against the buffer sleeve 773. The buffer sleeve 773 can be made of rubber.

[0053] In the embodiment, when the cylindrical rotating frame 2 drives the stop plate 24 to rotate, the stop plate 24 abuts against the buffer sleeve 773 of the buffer mechanism 77, the buffer sleeve 773 drives the buffer column 772 to move downward in the buffer cylinder 771, and the spring 774 is compressed. When the cylindrical rotating frame 2 reverses, the spring 774 restores the elastic deformation, driving the buffer sleeve 773 and the buffer column 772 to move upward, achieving reset. Since the buffer mechanism 77 is arranged, the cylindrical rotating frame 2 can be buffered and damped, making the movement of the cylindrical rotating frame 2 more stable. Since the buffer mechanism 77 is arranged on both sides of the support 1, when the cylindrical rotating frame 2 rotates to both sides, it can achieve the purpose of buffering and damping.

[0054] As shown in Figure 3As shown, the food processing turnover device further comprises four guide columns 78 vertically arranged in the cylindrical rotating frame 2. The upper conveying mechanism 3 is provided with four upper guide blocks 79, and each upper guide block 79 is slidingly sleeved on one guide column 78. The lower conveying mechanism 4 is provided with four lower guide blocks 79, and each lower guide block 79 is slidingly sleeved on one guide column 78. The guide column 78 is cylindrical, and the upper guide block 79 and the lower guide block 79 are both provided with a through guide hole, and the upper guide block 79 and the lower guide block 79 are sleeved on the guide column 78 through the guide hole. In this embodiment, since the guide column 78, the upper guide block 79 and the lower guide block 79 are arranged, the upper conveying mechanism 3 and the lower conveying mechanism 4 can be guided, and the phenomenon of movement deflection can be prevented.

[0055] In some embodiments, the upper conveying mechanism 3 and the lower conveying mechanism 4 are provided with photoelectric sensors for detecting the position of the food. When the food passes through the photoelectric sensor, the photoelectric sensor detects the food and transmits a signal to the controller of the turnover device, and the controller controls the rotation of the cylindrical rotating frame 2.
