Beneficial Effects

[0013] Compared with the prior art, the present invention provides an automatic feeding device and a method for feeding dough for cake production, which has the following beneficial effects: 1. An automatic loading device and a method for loading raw materials for cake production. By setting a transmission member and a linkage member, when the transmission platform is in a horizontal state, the transmission belt drives the carrying plate and the articles on the carrying plate to be transported. When the transmission platform needs to transport the raw materials upward or downward, the transmission member is controlled to move to one side of the transmission platform, and the transmission platform is controlled to rotate through a movable component, so as to control the end of the transmission platform where the raw materials are placed to move upward or downward, and keep the height of the end where the raw materials are output unchanged. During the rotation of the transmission platform, the linkage member is driven to operate, thereby driving the bearing frame to rotate, so that when the transmission platform rotates, the bearing frame is driven to rotate in the opposite direction, the bearing plate is controlled to be always in a horizontal state, and the raw materials are transported upward or downward for loading, thereby solving the problem that when the cake raw materials are fed upward or downward, they are affected by gravity and move downward or have a tendency to move downward during transportation, so that the side of the cake raw materials contacts the baffle on the mechanical device, thereby causing the cake raw materials to deform.

[0014] 2. An automatic loading device and a method for loading cake blanks for cake production. When the transmission belt drives the cake blank to move upward, the cake has a tendency to move downward and backward due to its own weight and inertia, which can easily cause the cake to shift in position and deform its overall shape. Through the movable hinge between the hinge plate and the rotating rod, the second torsion spring and the positioning groove, a certain buffering effect is exerted on the load-bearing plate and the cake blank on the load-bearing plate to prevent the cake from shifting in position.

[0015] 3.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes an automatic feeding device and a method for feeding dough for cake production.

When the movable component 5 drives one end of the transmission platform 21 to rotate, the transmission member 41 approaches the transmission platform 21, and the operation of the transmission member 41 drives the connecting member 42 to operate, thereby driving the support frame 31 and the support plates 32 on both sides to rotate, so that the support plates 32 are in a horizontal state.

[0021] Specifically, the blank is placed on the carrying plate 32, and then transported and loaded by the transmission belt 22 in the transmission device 4. When the transmission platform 21 is in a horizontal state, the transmission belt 22 rotates, and drives the carrying plate 32 and the blank on the carrying plate 32 to be transported and loaded to the subsequent processing equipment.

During the rotation of the transmission platform 21, the linkage member 42 is driven to operate, thereby driving the carrier frame 31 to rotate, so that when the transmission platform 21 rotates, it drives the carrier frame 31 to rotate in the opposite direction, and controls the carrying plate 32 to be always in a horizontal state and transport the blank upward or downward. By setting the transmission member 41 and the linkage member 42, when the transmission platform 21 is in a horizontal state, the transmission belt 22 drives the load-bearing plate 32 and the articles on the load-bearing plate 32 to be transported. When the transmission platform 21 needs to transport the blank material upward or downward, the transmission member 41 is controlled to move toward one side of the transmission platform 21, and the transmission platform 21 is controlled to rotate through the movable component 5, so as to control the end of the transmission platform 21 for placing the blank material to move upward or downward, and keep the height of the end for outputting the blank material unchanged. During the rotation of the transmission platform 21, the linkage member 42 is driven to operate, thereby driving the support frame 31 to rotate, so that when the transmission platform 21 rotates, it drives the support frame 31 to rotate in the opposite direction, controls the support plate 32 to be always in a horizontal state, and transports and loads the blank material upward or downward, thereby solving the problem that when the cake blank material is fed upward or downward, it is affected by gravity and moves downward or has a tendency to move downward during transportation, so that the side of the cake blank material contacts the baffle on the mechanical device, thereby causing the cake blank material to deform.

An automatic feeding device according to claim 7, characterized in that: The movable component includes a guide rail block, guide rail grooves are opened on both sides of the top of the base, the guide rail block is fixedly arranged at the bottom of the base plate, the guide rail block is slidably arranged in the guide rail groove, a slide groove is opened on the top of the base plate, and sliders are fixedly connected on both sides of the top plate, and the sliders are slidably arranged in the slide grooves.

9. An automatic feeding device according to claim 8, characterized in that: A second screw is rotatably connected in the slide groove via a bearing, the second screw is threadedly connected to the top plate, a cross plate is fixedly connected between the two bottom plates, a rotating rod is rotatably connected in the cross plate via a bearing, a bevel gear set is fixedly installed between the two ends of the rotating rod and the two second screws, a third motor is fixedly connected to one side of the bottom plate, and an output end of the third motor is fixedly connected to one end of the rotating rod.

10. A method for feeding a raw material for cake production, characterized in that: Using an automatic feeding device as described in any one of claims 1 to 9, the specific steps are: The blank is placed on the carrier plate, and then transported and loaded through the transmission belt in the transmission device. When the transmission platform is in a horizontal state, the transmission belt rotates and drives the carrier plate and the blank on the carrier plate to be transported and loaded to subsequent processing equipment. When the blank needs to be transported upward or downward, the transmission member is controlled to move to one side of the transmission platform, and the transmission platform is controlled to rotate through the movable component, so as to control the end of the transmission platform where the blank is placed to move upward or downward, and keep the height of the end where the blank is output unchanged. During the rotation of the transmission platform, the linkage member is driven to operate, thereby driving the carrier frame to rotate, so that when the transmission platform rotates, it drives the carrier frame to rotate in the opposite direction, controls the carrier plate to always be in a horizontal state, and transports the blank upward or downward.
