Description

Technical Field

[0001] This utility model relates to a dough clamping mechanism, belonging to the field of food processing technology. Background Technology

[0002] In the food industry, many types of cakes require the dough to be flattened into cakes during the raw processing stage, and then covered with film paper on both sides of the cakes. The machine used to process the dough is called a forming machine, and the machine used to flatten and cover with film paper is called a film covering machine.

[0003] In traditional production, the process of feeding dough to the coating machine is done manually. This process requires a lot of manpower and is quite labor-intensive. Manual transfer is not only labor-intensive and inefficient, making it difficult to meet the continuous needs of large-scale production, but also carries the risk of dough breakage and contamination due to improper manual operation, affecting the stability of product quality. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a dough blank clamping mechanism.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A dough blank clamping mechanism includes a coating machine, the coating machine including a coating machine frame and a coating assembly, the coating assembly being disposed on one side of the coating machine frame, a transfer frame being disposed on one side of the coating machine frame, a transfer conveyor belt being disposed on the upper side of the transfer frame, the transfer conveyor belt being disposed on one side of the coating assembly, a dough blank centering conveyor being disposed on the upper side of the transfer frame and near the transfer conveyor belt, and an automatic dough blank transfer assembly being disposed on the upper side of the transfer frame and between the dough blank centering conveyor and the transfer conveyor belt.

[0006] Through the above technical solution, the cake clamping mechanism is based on a laminating machine. The laminating frame of the laminating machine provides installation support for the laminating assembly. The laminating assembly completes the cake laminating operation on one side of the laminating frame. The transfer frame set on one side of the laminating frame provides an installation carrier for the transfer conveyor belt, the cake centering conveyor assembly, and the cake automatic transfer assembly. The transfer conveyor belt is located on one side of the laminating assembly and is used to receive the transferred cake. The cake centering conveyor assembly is set on the upper side of the transfer frame and close to the transfer conveyor belt to correct the position of the conveyed cake. The cake automatic transfer assembly is located between the cake centering conveyor assembly and the transfer conveyor belt to realize the transfer of the corrected cake from the correction conveyor assembly to the transfer conveyor belt.

[0007] By setting up a transfer frame that integrates a transfer conveyor belt, a correction conveyor component, and an automatic transfer component, the automated transfer connection of the cake blanks before coating is realized, avoiding the tediousness of manual transfer, improving the continuity and efficiency of cake blank transfer, and providing a foundation for the precise coating process of the subsequent cake blanks.

[0008] Preferably, the dough blank centering conveying assembly includes a support base, which is disposed on the upper side of the transfer frame. A dough blank conveyor belt is disposed on the upper side of the support base. Side plates are disposed on both sides of the dough blank conveyor belt. A centering cylinder is disposed on the upper side of the side plate. A push plate is disposed on the shaft end of the centering cylinder.

[0009] Through the above technical solution, in the blank centering conveyor assembly, the support base is fixed on the upper side of the transfer frame to provide installation support for the blank conveyor belt. The blank conveyor belt is used to transport the blanks to be corrected. The side plates on both sides of the blank conveyor belt provide the installation base for the centering cylinder. When the blank is offset on the conveyor belt, the shaft end of the centering cylinder extends, driving the push plate to move towards the blank. Through the synergistic action of the push plates on both sides, the offset blank is pushed to the center position of the conveyor belt. After the correction is completed, the shaft end of the centering cylinder retracts and the push plate resets.

[0010] By using a centering cylinder to drive a pusher plate to correct the position of the blank during transport, the position accuracy of the blank during transport can be effectively guaranteed, avoiding problems such as subsequent transfer component clamping errors or inaccurate transfer positions caused by blank offset, thus improving the precision of blank processing.

[0011] Preferably, the automatic dough transfer assembly includes a support frame, which is disposed on the upper side of the transfer frame. A slide groove is provided on the upper side of the support frame, and upright plates are provided on both sides of the slide groove. A motor is provided on one side of the upright plate, and a threaded rod is provided on the shaft end of the motor. A slider is threadedly connected to the outer side of the threaded rod. The slider is slidably connected in the slide groove, and a lifting cylinder is provided on the lower side of the slider. A pneumatic gripper is provided on the piston rod end of the lifting cylinder.

[0012] Through the above technical solution, the bracket of the automatic dough transfer component is fixed on the upper side of the transfer frame. The slide groove on the bracket provides sliding guidance for the slider. The upright plate is fixed on both sides of the slide groove to provide installation support for the motor. When the motor is working, its shaft end drives the threaded rod to rotate. Since the slider and the threaded rod are threadedly connected and slidably connected in the slide groove, the rotation of the threaded rod drives the slider to move back and forth along the slide groove. The lifting cylinder on the lower side of the slider can drive the pneumatic gripper to move up and down. The pneumatic gripper is used to grip the dough. Through the horizontal movement of the slider and the lifting action of the lifting cylinder, the dough is transferred from the dough conveyor belt to the transfer conveyor belt.

[0013] By using a motor to drive a threaded rod to move a slider, and combining this with a lifting cylinder to lift a pneumatic gripper, the automated gripping and transfer of the blank is achieved, replacing the manual gripping and transfer method, reducing labor costs. At the same time, the mechanical structure controls the transfer trajectory, improving the stability and accuracy of the transfer, and enhancing overall production efficiency.

[0014] Preferably, there are two lifting cylinders, wherein a photoelectric sensor is provided on the bottom side of the pneumatic gripper on the lifting cylinder near the end of the cake conveyor belt, and a position sensor is provided on the upper side of the bracket and at a position opposite to the end of the transfer conveyor belt.

[0015] Through the above technical solution, the two lifting cylinders correspond to different working positions. The photoelectric sensor on the bottom side of the pneumatic gripper on the lifting cylinder near the end of the cake conveyor belt can detect the position and presence of cakes on the cake conveyor belt in real time, and send a feedback signal when a cake is detected. The position sensor on the upper side of the bracket relative to the end of the transfer conveyor belt is used to detect the position of the end of the transfer conveyor belt and whether it is ready to receive cakes. The signal fed back by the sensor is used to control the timing of the operation of the motor, lifting cylinder and pneumatic gripper to ensure the accuracy of picking up and placing cakes.

[0016] By setting up photoelectric sensors and position sensors, real-time detection of the position of the biscuit blank and the receiving status of the transfer conveyor belt is realized. This enables the automatic transfer component to accurately control its actions based on the detection signals, avoiding problems such as empty rotation of the clamping mechanism and misplacement caused by unclear biscuit blank position or the transfer conveyor belt not being ready. This further improves the reliability and automation of the transfer process.

[0017] Preferably, the lower side of the transfer frame is provided with several rollers.

[0018] With the above technical solution, several rollers on the underside of the transfer frame are in contact with the ground. When the position of the transfer frame needs to be adjusted, an external force is applied to push the transfer frame, and the rollers roll on the ground, driving the entire transfer frame to the required position.

[0019] The rollers make the transfer frame easier and less labor-intensive to move, allowing its position to be adjusted according to the layout requirements of the production site. This enhances the flexibility and adaptability of the equipment and reduces the labor intensity of adjusting the equipment position.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, by setting a transfer frame on one side of the coating machine frame and integrating a transfer conveyor belt, a blank centering and conveying component, and an automatic blank transfer component, realizes the automated connection of the blank from the conveying process to the subsequent coating process before coating. It effectively replaces the manual transfer method, reduces manual intervention, lowers labor costs, and ensures the continuity and stability of blank transfer, laying the foundation for the efficient development of subsequent blank coating processing.

[0021] In this invention, the blank centering and conveying component drives the push plate to move through the centering cylinder on the side plate. This can accurately correct the blank that has shifted position during the conveying process, ensuring that the blank is always in the center position of the conveyor belt. This design effectively avoids the problem of misalignment and missed clamping of subsequent transfer components caused by blank shift, improves the consistency of blank conveying position, reduces the processing error rate caused by position deviation, and improves the overall accuracy of blank processing.

[0022] This invention relates to an automatic dough blank transfer component that uses a motor-driven threaded rod to move a slider along a chute, combined with a lifting cylinder to drive a pneumatic gripper for lifting. This achieves fully automated gripping and transfer of dough blanks from the correction conveyor to the transfer conveyor belt. This mechanical structure replaces the traditional manual gripping and transfer mode, which not only reduces the labor intensity and human error of manual operation, but also ensures the accuracy of the transfer trajectory through the stability of mechanical transmission, significantly improving the efficiency and stability of dough blank transfer.
