[0027] Embodiment 1

[0028] As shown in the Figure 1 accompanying drawings, this embodiment provides an automatic cake-unwrapping and feeding device for feeding a knotting machine, which is used to unwrap a gunpowder cake and transfer it to the feeding rack 200 of the knotting machine 100. The feeding rack 200 is inclined and arranged at the feeding end of the knotting machine, and a feeding station 200.1 is provided on the feeding rack 200. The automatic cake-unwrapping and transferring device includes a cake placing rack 1, a two-axis linear module 2, a pressing plate assembly 3, and an electric gripper 4, wherein:

[0029] As shown in the Figure 1 accompanying drawings, the cake placing rack 1 is arranged parallel and side by side with the feeding rack 200 on the outside of the feeding rack, and is used to place and fix the gunpowder cake mold 300. Preferably, as shown in the Figure 3 accompanying drawings, the cake placing rack 1 includes a supporting bottom plate 1.1, guiding strips 1.2 arranged on both sides of the supporting bottom plate, and a limiting baffle 1.3 arranged at the bottom of the supporting bottom plate. A sliding groove is arranged on the inner side of the guiding strip 1.2, and a convex edge slidably connected with the sliding groove is arranged on the gunpowder cake mold 300. This design enables the position of the gunpowder cake mold to be limited after it enters the cake placing rack, so as to ensure that the electric gripper can smoothly grab the gunpowder cake inside. As shown in the Figure 2 and the Figure 4As shown in the figure, the pressing plate assembly 3 and the electric gripper 4 are both arranged on the Z-axis module of the two-axis linear module 2, and are respectively used for pressing the gun cake and grasping the gun cake 400. Specifically, the two-axis linear module 2 is composed of an X-axis module 2.1 and a Z-axis module 2.2. The X-axis module realizes the reciprocating movement of the electric gripper between the cake placing rack and the feeding bottom mold, and the Z-axis module realizes the up and down movement of the electric gripper. The two-axis linear module 2 is arranged between the cake placing rack 1 and the feeding rack 200, and is used to transfer the grasped gun cake into the feeding bottom mold.

[0030] As shown in the Figure 4 figure, the pressing plate assembly 3 is arranged between the two jaws of the electric gripper 4, and it includes a pressing plate 3.1, a support column 3.2, a support plate 3.3, a guide column 3.4 and a spring 3.5. The support plate 3.3 is fixedly installed at the bottom of the mounting seat of the electric gripper 4. The pressing plate 3.1 is arranged below the support plate 3.3, and a support column 32 is arranged in the middle thereof. The support column 3.2 movably passes through the pressing plate 3.1 and is connected to a limit block, and the limit block is used to prevent the support column from coming out of the support plate. A plurality of guide columns 3.4 are arranged on the pressing plate 3.1, and the guide columns 3.4 movably pass through the support plate 3.3. The spring 3.5 is arranged on the guide column 3.4 and is located between the pressing plate 3.1 and the support plate 3.3. During specific operation, when the electric gripper runs to the cake placing rack station, the two-axis linear module controls the electric gripper to move downward. During the downward movement, the support plate presses against the gun cake in the gun cake mold until it reaches the bottom after the downward movement. Then, the electric gripper grabs the gun cake. After grabbing, the electric gripper is controlled to move upward, and the gun cake is transferred into the feeding bottom mold.

[0031] The feeding method of the feeding device of the above-mentioned knotting machine includes the following steps:

[0032] S1, Place the gun cake mold filled with gun cakes on the cake placing rack and position it;

[0033] S2, Control the two-axis linear module to move the electric gripper to face the gun cake, and control the electric gripper and the pressing plate assembly to move downward. The pressing plate assembly presses the gun cake, and at the same time the electric gripper grabs the gun cake;

[0034] S3, Control the two-axis linear module to move upward, and at the same time control the electric gripper to move to the position of the feeding bottom mold, and place the gun cake on the feeding station of the feeding rack;

[0035] During specific implementation, the gun cake mold can be placed at the end of the cake placing rack by a manipulator. The cake placing rack slides to its bottom under the action of its own weight. Subsequently, the two-axis linear module controls the electric gripper to grab the gun cake in the gun cake mold and transfer it to the feeding station of the feeding rack.

[0036] Embodiment 2

[0037] On the basis of Embodiment 1, as shown in the Figure 3As shown, the cake placing rack 1 further includes a first electric push rod 5. The first electric push rod 5 is fixed on the support bottom plate 1.1, and its push rod is connected to the limit baffle 1.3. The limit baffle 1.3 is movably installed at the bottom of the support bottom plate 1.1. This design enables the cannon cake mold to retract the limit baffle by using the first electric push rod after grasping and transferring the cannon cake inside. At this time, the cannon cake mold freely falls under the action of its own weight.

[0038] Preferably, as shown in the appendix Figure 2 As shown, a recovery station 6 for cannon cake molds is further provided below the cake placing rack 1 for recovering the cannon cake molds after the cakes are removed.

[0039] Embodiment III

[0040] On the basis of Embodiment I or Embodiment II, as shown in the appendix Figure 1 and the appendix Figure 2 As shown, the automatic cake removing and feeding device of this embodiment further includes a blanking guiding chute 7 provided on the cake placing rack 1 and a blocking assembly 8 provided between the blanking guiding chute 7 and the cake placing rack 1. The two side plates at one end of the blanking guiding chute 7 close to the cake placing rack 1 are also provided with chutes for slidably connecting with the cannon cake mold 300. The blocking assembly 8 includes a blocking block 8.1 and a second electric push rod 8.2 connected to the blocking block. The second electric push rod 8.2 is installed on the cake placing rack 1, and the blocking block 8.1 is provided between the cake placing rack 1 and the blanking guiding chute 7. This design enables the blanking guiding chute to accommodate multiple cannon cake molds, isolate them through the blocking assembly, and control the cannon cake molds to enter the cake placing rack one by one, realizing continuous production.

[0041] The feeding method of the feeding device of the above-mentioned knotting machine includes the following steps:

[0042] S1. Place the cannon cake mold with cannon cakes into the blanking guiding chute. The cannon cake mold slides down to the cake placing rack under the guiding action of the blanking guiding chute. When the cannon cake mold slides to the cake placing rack, the blocking assembly acts to block the next cannon cake mold from entering the cake placing rack;

[0043] S2. Control the two-axis linear module to move the electric gripper to face the cannon cake, and control the electric gripper and the pressing plate assembly to move downward. The pressing plate assembly presses the cannon cake, and at the same time the electric gripper grabs the cannon cake;

[0044] S3. Control the two-axis linear module to move upward, and at the same time control the electric gripper to move to the position of the feeding bottom mold, and place the cannon cake on the feeding station of the feeding rack;

[0045] The above are only embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structural or equivalent process transformation made by using the content of the specification of the present utility model, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present utility model.
