Description

Technical Field

[0001] This invention relates to the field of cake making, and in particular to a highly efficient automatic cake flipping and unmolding machine and its unmolding method. Background Technology

[0002] The cake-making process generally involves placing the raw materials into a mold, baking it, and then unmolding the baked cake. Current cake unmolding methods are mainly divided into manual unmolding and machine unmolding. Manual unmolding involves manually turning the mold over and tapping it to release the cake. This requires waiting for the mold to cool, resulting in low efficiency and poor hygiene, making it unsuitable for rapid, mass production. Machine unmolding includes pinhole and blower-type unmolding. Machine unmolding easily leaves pinholes and suction marks on the cake surface, affecting the appearance of the finished product. Summary of the Invention

The demolding shaft is provided at the end of the truss facing away from the demolding slide. The demolding shaft rotates on the truss. The demolding cone is connected to the bottom end of the demolding shaft through the connecting rod. The connecting rod is inclined at the bottom end of the demolding shaft, and the demolding cone rotates at the bottom end of the connecting rod.

[0012] The positioning mechanism includes a positioning slide and a vacuum suction cup. The positioning slide is provided on the side surface of the stand near the flipping frame. The positioning slide is located at the bottom of the stand and moves up and down. The vacuum suction cup is provided at the end of the positioning slide near the flipping frame.

[0013] The cutting mechanism includes a cutting line, a cutting slide, and a cutting frame. Both ends of the cutting line are connected to the cutting slide. The two cutting slides are respectively located on the two cutting frames and move left and right. The two cutting frames are respectively connected to both sides of the positioning slide. The cutting line is located below the vacuum suction cup.

[0014] As a further improvement, the clamping plate is driven by a clamping cylinder located on the lower plate.

[0015] As a further improvement, the bottom surface of the lower plate is provided with an ear seat, on which a drive rod is hinged, and the hinge point is located in the middle of the drive rod. The first end of the drive rod is connected to the lifting rod, and the second end of the drive rod is connected to an electric push rod. The electric push rod is located on the bottom surface of the lower plate and is used to drive the lifting rod to rise and fall.

[0016] As a further improvement, the bottom surface of the mold base plate is provided with a downwardly protruding retaining ring. The retaining ring is made of metal, and its outer diameter is larger than the diameter of the opening. The retaining ring and the opening cooperate to form a locking structure.

[0017] As a further improvement, the upper surface of the base is provided with a downwardly recessed guide rail, the two sides of which are triangular, and the bottom surface of the frame is provided with a guide part that matches the guide rail, the guide part being located within the guide rail and moving back and forth.

[0018] As a further improvement, the first connecting arm is provided with a first connecting pin, and the bottom of the flip slide is provided with a second connecting arm, which is provided with a second connecting pin.

[0019] As a further improvement, the demolding shaft is driven by a demolding motor mounted on the truss.

[0020] As a further improvement, the bottom edge of the demolded cone is smooth to form a curved surface.

[0021] A highly efficient cake automatic flipping and demolding machine's demolding method, characterized by the following steps:

[0022] First, place the mold containing the cake base on the lower plate, positioning it between the clamping plates. Second, clamp the mold cylinder to the lower plate using the clamping plates. Third, move the mold upwards using the flipping frame until it reaches the position of the demolding mechanism. Fourth, move the stand and the demolding slide to bring the demolding cone into contact with the edge of the cake base adhering to the mold cylinder, gently pressing down on the cake base. Fifth, rotate the demolding shaft and the demolding cone. Since the demolding shaft and mold cylinder are coaxial, the demolding cone rotates and presses against the surface of the cake base, separating all edges of the cake base from the inner wall of the mold cylinder. Sixth, once all edges of the cake base are separated from the inner wall of the mold cylinder, reset the stand and the demolding slide. Seventh, raise the lifting rod, passing through the through hole and opening, and lift the mold base plate upwards, detaching it from the opening. During this process, the mold base plate removes the cake base from the mold cylinder. Step 8: Push outwards; Step 9: Move the flipping slide upwards, until the guide pin abuts against the frame on both sides of the notch. At this point, the frame remains stationary despite the force, while the guide pin rolls along the inner wall of the frame, causing the flipping shaft to rotate the flipping frame until the first connecting arm abuts against the guide pin again. At this point, the upper and lower plates are reversed, tilting the cake base and mold bottom plate from the lower plate onto the upper plate. The upper plate is raised and lowered during this process. Step 10: Move the flipping frame downwards to the station where the positioning mechanism is located and stop. Step 11: By moving the stand and raising and lowering the positioning slide, the vacuum suction cup is pressed tightly against the surface of the mold bottom plate and adsorbs the mold bottom plate. Step 12: Move the cutting line by moving the cutting slide, so that the cutting line is pressed tightly against the mold bottom plate to cut the cake base. Step 13: When the vacuum suction cup resets, it can remove the separated mold bottom plate. Step 14: Remove the cake base from the upper plate.

[0023] As can be seen from the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages: In use, the mold containing the cake base is placed on the lower plate and clamped and fixed. By rotating and pressing the demolding cone tightly against the surface of the cake base, the entire edge of the cake base is separated from the inner wall of the mold cylinder. Then, by using the rising lifting rod, the mold base plate and the cake base are lifted upwards. Then, with the cooperation of the flipping drive mechanism, the flipping frame is rotated 180 degrees, tilting the cake base and mold base plate in the mold on the lower plate onto the upper plate. Then, the mold base plate and the cake base are fixed by vacuum suction cups. Then, by moving the cutting line, the mold base plate and the cake base are separated, thereby quickly completing the demolding of the cake base. The present invention does not require manual operation during the flipping and demolding process, which can greatly improve the demolding efficiency. Moreover, mechanical demolding is more hygienic and aesthetically pleasing, improving product quality. Attached Figure Description

[0040] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0041] As attached Figure 1 As shown, an efficient automatic cake flipping and demolding machine includes a base 1, a flipping frame 2, a mold 3, a flipping drive mechanism 4, a stand 5, a demolding mechanism 6, a positioning mechanism 7, and a cutting mechanism 8.

[0042] As attached Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the tilting frame 2 includes a lower plate 21, an upper plate 22 and clamping plates 24. The lower plate 21 and the upper plate 22 are arranged in parallel, and the upper plate 22 is located above the lower plate 21 and moves up and down. Several clamping plates 24 are located on the upper surface of the lower plate 21 and extend and retract horizontally. The several clamping plates 24 are arranged in a ring. The clamping plates 24 are driven by clamping cylinders 241 located on the lower plate 21. In use, place the mold 3 containing the cake base 34 on the lower plate 21, so that the mold 3 is positioned between the clamping plates 24. Then, drive the clamping plates 24 through the clamping cylinder 241 to clamp and fix the mold 3 on the lower plate 21, preventing the mold 3 from falling. Then, rotate the flipping frame 2 180 degrees to invert the upper plate 22 and the lower plate 21, tilting the cake base 34 in the mold 3 on the lower plate 21 onto the upper plate 22, thus completing the cake demolding. During the process, the upper plate 22 can be raised and lowered to adjust the distance between the lower plate 21 and the upper plate 22, so that the cake base 34 can fall smoothly onto the upper plate 22 without causing impact damage to the cake base 34.

[0043] As attached Figure 2 , Figure 7 , Figure 8 and Figure 9As shown, the 180-degree rotation of the aforementioned flipping frame 2 is driven by a flipping drive mechanism 4. The flipping drive mechanism 4 includes a base 41, a frame 42, a guide frame 422, a column 43, a flipping slide 44, a flipping shaft 45, a guide pin 46, a first connecting arm 47, and a limiting pin 410. The base 41 and the column 43 are both fixed to the upper surface of the base 1. The upper surface of the base 41 is provided with a downwardly recessed guide rail 411, the two sides of which are triangular. The bottom surface of the frame 42 is provided with a guide portion 423 that matches the guide rail 411. When the frame 42 moves back and forth on the base 41, the guide portion 423 moves back and forth within the guide rail 411. The guide rail 411 guides and restricts the frame 42, allowing the frame 42 to move smoothly back and forth. The bottom inner wall of the frame 42 is provided with a guide frame 422, which is triangular, and the top of the frame 42 is provided with a notch 421 corresponding to the guide frame 422. Additionally, the tilting slide 44 is mounted on the column 43 and moves up and down. A tilting shaft 45 passes through the tilting slide 44 and rotates on it. The first end of the tilting shaft 45 passes through the inside of the frame 42 and connects to the lower plate 21. Two protruding guide pins 46 are provided on the outer side of the first end of the tilting shaft 45. The angle between the center of the two guide pins 46 and the axis of the tilting shaft 45 is 120 degrees. At the same time, a protruding first connecting arm 47 is provided at the end of the tilting shaft 45. The first connecting arm 47 is elastically connected to the tilting slide 44. Specifically, the first connecting arm 47 is provided with a first connecting pin 471. The bottom of the tilting slide 44 is provided with a second connecting arm 48, which is provided with a second connecting pin 481. A spring 49 is provided between the first connecting pin 471 and the second connecting pin 481. The two ends of the spring 49 are respectively connected to the first connecting pin 471 and the second connecting pin 481. Furthermore, the flip slide 44 is provided with two symmetrical limit pins 410, which are located on both sides of the flip shaft 45. When the first connecting arm 47 abuts against the guide pin 46, the lower plate 21 is in a horizontal state and the spring 49 is in a stretched state.

[0044] As attached Figures 7 to 9As shown, during the flipping process, the flipping slide 44 drives the flipping frame 2 to move downwards until the guide pin 46 contacts the guide frame 422. Then, the flipping frame 2 continues to move downwards. Under the pushing force of the guide pin 46, the frame 42 and the guide frame 422 move back and forth on the base 41 until the base 41 moves to the set limit. Then, the flipping slide 44 drives the flipping frame 2 to move upwards until another guide pin 46 abuts against the frame 42 on both sides of the notch 421. Due to the restriction of the frame 42 and the horizontal inner wall of the top of the frame 42, the force on the frame 42 will only maintain... Since the guide pin 46 remains stationary and does not move back and forth, it can only roll along the inner wall of the frame 42. At this time, the flipping shaft 45, under the force of the guide pin 46, drives the flipping frame 2 to rotate. During this process, the flipping frame 2 drives the first connecting arm 47 to rotate, further stretching the spring 49. When the flipping frame 2 rotates beyond a certain angle, the spring 49 reaches its maximum stretch value. Under the elastic restoring force of the spring 49, the flipping frame 2 can complete a 180-degree flip until the first connecting arm 47 abuts against the guide pin 46 again, thereby realizing the tilting and demolding of the cake base 34. Then, the flipping slide 44 drives the flipped flipping frame 2 to move downward again, repeating the above steps to flip the flipped flipping frame 2 180 degrees again for use.

[0045] As attached Figure 1 , Figure 10 , Figure 11 and Figure 12As shown, the stand 5 is located on the upper surface of the base 1 and moves left and right. The flipping frame 2 is located between the stand 5 and the flipping drive mechanism 4. The top of the stand 5 is provided with a demolding mechanism 6, which includes a demolding slide 61, a truss 62, a demolding shaft 63, a connecting rod 64, and a demolding cone 65. The demolding slide 61 and the truss 62 are vertically connected. The demolding slide 61 is provided on the side surface of the stand 5 near the flipping frame 2. The demolding slide 61 is located on the top of the stand 5 and moves up and down. The end of the truss 62 facing away from the demolding slide 61 is provided with a demolding shaft 63. The demolding shaft 63 is driven to rotate by a demolding motor 66 located on the truss 62. The demolding cone 65 is connected to the bottom end of the demolding shaft 63 through the connecting rod 64. The connecting rod 64 is inclined at the bottom end of the demolding shaft 63, and the demolding cone 65 is located at the bottom end of the connecting rod 64 and rotates. Before tilting and demolding the cake base 34, the tilting frame 2 moves the mold 3 upwards to the position of the demolding mechanism 6 and stops. Through the movement of the stand 5 and the raising and lowering of the demolding slide 61, the demolding cone 65 contacts the edge of the cake base 34 adhering to the mold cylinder 31, and gently presses down on the cake base 34, causing it to slightly indent and separating the cake base 34 from the mold cylinder 31. Then, the demolding motor 66 drives the demolding shaft 63 and the demolding cone 65 to rotate. Because the demolding shaft 63 is coaxial with the mold cylinder 31, the demolding cone 65 can separate all edges of the cake base 34 from the inner wall of the mold cylinder 31, facilitating rapid demolding of the cake base 34 while effectively ensuring the smoothness and flatness of the sides of the cake base 34, reducing the breakage rate. During the process, because the cake base 34 has a certain degree of elasticity, gently pressing the cake base 34 will not cause breakage. Furthermore, the bottom edge of the demolded cone 65 is smoothly formed into a curved surface 651. The setting of this curved surface 651 can further reduce the risk of damage caused by the demolded cone 65 pressing on the cake base 34.

[0046] It is worth mentioning that, as shown in the attached document Figures 3 to 6As shown, mold 3 includes mold cylinder 31 and mold base plate 33. The upper surface of mold cylinder 31 has an inwardly recessed receiving space, and the bottom surface of the receiving space has an opening 32. Mold base plate 33 is placed into the receiving space, and mold base plate 33 is detachably connected to opening 32. Specifically, the bottom surface of mold base plate 33 has a downwardly protruding retaining ring 331. The retaining ring 331 is made of metal, specifically stainless steel, which has a certain degree of metal elasticity and is not easily bent or damaged. The outer diameter of retaining ring 331 is slightly larger than the diameter of opening 32. During assembly, mold base plate 33 is placed into mold cylinder 31, and mold base plate 33 is pressed down, causing retaining ring 331 to embed into opening 32. During the process, retaining ring 331 retracts inward and locks into opening 32, so that retaining ring 331 and opening 32 cooperate to form a locking structure. Then, cake raw materials are baked in the receiving space and mold base plate 33 to form cake base 34. In addition, since the lower plate 21 has a through hole 23, and the bottom surface of the lower plate 21 is provided with several lifting rods 25 arranged around the through hole 23, the lifting rods 25 are arranged to rise and fall on the bottom surface of the lower plate 21, and the lifting rods 25 can pass upward through the through hole 23. After the demolding cone 65 rotates and separates the edge of the cake base 34 from the inner wall of the mold cylinder 31, the lifting rods 25 can rise, pass through the through hole 23 and the opening 32, and lift the mold base plate 33 upward, so that the mold base plate 33 separates from the opening 32. During the process, the mold base plate 33 pushes the cake base 34 out of the mold cylinder 31. After the flipping frame 2 flips, it is easier to pour the cake base 34 and the mold base plate 33 out of the mold cylinder 31, which facilitates the demolding of the cake. Furthermore, the clamping plate 24 is arranged around the through hole 23. After the mold cylinder 31 is placed on the upper surface of the lower plate 21 and the clamping plate 24 extends and retracts to clamp the mold cylinder 31, the opening 32 of the mold cylinder 31 corresponds to the through hole 23 of the lower plate 21, ensuring the use of the lifting rod 25.

[0047] Among them, as attached Figure 6 As shown, the lifting rod 25 is driven by an electric push rod 253 located on the bottom surface of the lower plate 21. Specifically, the bottom surface of the lower plate 21 is provided with an ear seat 252, on which a drive rod 251 is hinged, with the hinge point located in the middle of the drive rod 251. The first end of the drive rod 251 is connected to the lifting rod 25, and the second end of the drive rod 251 is connected to the electric push rod 253. In use, the electric push rod 253 causes the drive rod 251 to rotate around the ear seat 252, thereby raising or lowering the lifting rod 25.

[0048] In addition, as attached Figure 10 , Figure 13 , Figure 14 and Figure 15As shown, the bottom of the stand 5 is provided with a positioning mechanism 7, which includes a positioning slide 71 and a vacuum suction cup 72. The positioning slide 71 is provided on the side surface of the stand 5 near the flipping frame 2. The positioning slide 71 is located at the bottom of the stand 5 and moves up and down. The vacuum suction cup 72 is provided at the end of the positioning slide 71 near the flipping frame 2. At the same time, a cutting mechanism 8 is provided on the positioning slide 71. The cutting mechanism 8 includes a cutting line 81, a cutting slide 82 and a cutting frame 85. Both ends of the cutting line 81 are connected to the cutting slide 82. The two cutting slides 82 are located on the two cutting frames 85 and move left and right. The two cutting frames 85 are connected to the two sides of the positioning slide 71 respectively. The cutting line 81 is located below the vacuum suction cup 72. After the flipping rack 2 completes a 180-degree flip, tilting the cake base 34 along with the mold base plate 33 onto the upper plate 22, the flipping rack 2 moves the cake base 34 down to the station where the positioning mechanism 7 is located and stops. Through the movement of the stand 5 and the raising and lowering of the positioning slide 71, the vacuum suction cup 72 is pressed tightly against the surface of the mold base plate 33 and adheres to it, thus fixing the mold base plate 33 and the cake base 34. Then, the cutting slide 82 moves the cutting line 81, causing the cutting line 81 to cut the cake base 34 tightly against the mold base plate 33, thereby separating the mold base plate 33 from the cake base 34 and completing the demolding of the cake base 34. (See attached image) Figure 16 As shown, when the vacuum suction cup 72 is reset, the vacuum suction cup 72 can remove the separated mold base plate 33 along with it. Finally, the cake base 34 on the upper plate 22 can be removed manually.

[0049] In summary, when using this invention, the mold 3 containing the cake base 34 is placed on the lower plate 21 and clamped in place. By rotating and pressing the demolding cone 65 against the surface of the cake base 34, all edges of the cake base 34 are separated from the inner wall of the mold cylinder 31. Then, the rising lifting rod 25 lifts the mold base plate 33 and the cake base 34 upwards. Subsequently, with the cooperation of the flipping drive mechanism 4, the flipping frame 2 rotates 180 degrees, tilting the cake base 34 along with the mold base plate 33 from the mold 3 on the lower plate 21 onto the upper plate 22. The vacuum suction cup 72 then adheres and fixes the mold base plate 33 and the cake base 34. Finally, by moving the cutting line 81, the mold base plate 33 is separated from the cake base 34, thus quickly completing the demolding of the cake base 34. This invention requires no manual operation during the flipping and demolding process, which can greatly improve demolding efficiency. Moreover, mechanical demolding is more hygienic and aesthetically pleasing, improving product quality.

[0050] A highly efficient cake automatic flipping and demolding machine's demolding method, characterized by the following steps:

[0051] The first step is to place the mold 3 containing the cake base 34 on the lower plate 21, so that the mold 3 is positioned between the clamping plates 24;

[0052] The second step is to drive the clamping plate 24 by the clamping cylinder 241 so that the clamping plate 24 clamps and fixes the mold cylinder 31 of the mold 3 on the lower plate 21 to prevent the mold 3 from falling.

[0053] The third step is to move the tilting frame 2 up to the position where the mold 3 is located and then stop.

[0054] The fourth step involves moving the stand 5 and raising and lowering the demolding slide 61 to make the demolding cone 65 contact the edge of the cake base 34 and the mold cylinder 31, and gently press the cake base 34 downwards to make the cake base 34 slightly concave, thus separating the cake base 34 from the edge of the mold cylinder 31.

[0055] Fifth step: The demolding motor 66 drives the demolding shaft 63 and the demolding cone 65 to rotate. Since the demolding shaft 63 is coaxial with the mold cylinder 31, the demolding cone 65 rotates and presses against the surface of the cake base 34, separating all the edges of the cake base 34 from the inner wall of the mold cylinder 31. This facilitates the quick demolding of the cake base 34 while effectively ensuring the smoothness and flatness of the sides of the cake base 34, reducing the breakage rate of the cake base 34. During the process, since the cake base 34 has a certain degree of elasticity, gently pressing the cake base 34 will not cause damage to the cake base 34.

[0056] Step 6: After all the edges of the cake base 34 have separated from the inner wall of the mold cylinder 31, reset the stand 5 and the demolding slide 61.

[0057] Step 7: The electric push rod 253 causes the drive rod 251 to rotate around the ear seat 252, thereby causing the lifting rod 25 to rise, pass through the through hole 23 and the opening 32, and push the mold base plate 33 upward, so that the mold base plate 33 is separated from the opening 32. During the process, the mold base plate 33 pushes the cake base 34 out of the mold cylinder 31.

[0058] Step 8: The tilting slide 44 drives the tilting frame 2 upward until the guide pin 46 abuts against the frames 42 on both sides of the notch 421. Due to the constraint of the frames 42 and the horizontal inner wall of the top of the frames 42, the frames 42 will remain stationary and will not move back and forth. Therefore, the guide pin 46 can only roll along the inner wall of the frames 42. At this time, the tilting shaft 45 drives the tilting frame 2 to rotate under the force of the guide pin 46. During the process, the tilting frame 2 drives the first connecting arm 47 to rotate, further stretching the spring 49. When the tilting frame 2 rotates beyond a certain point... When the spring 49 reaches its maximum tension, the flipping frame 2 can complete a 180-degree flip under the elastic restoring force of the spring 49 until the first connecting arm 47 abuts against the guide pin 46 again. At this time, the upper plate 22 and the lower plate 21 are reversed, and the cake base 34 in the mold 3 on the lower plate 21, along with the mold base plate 33, is tilted onto the upper plate 22. During the process, the upper plate 22 can be raised and lowered to adjust the distance between the lower plate 21 and the upper plate 22, so that the cake base 34 can fall smoothly onto the upper plate 22 without causing impact damage to the cake base 34.

[0059] Step 9: Move the cake base 34 down to the position where the positioning mechanism 7 is located, then stop.

[0060] Step 10: By moving the stand 5 and raising and lowering the positioning slide 71, the vacuum suction cup 72 is pressed tightly against the surface of the mold base plate 33 and adsorbs the mold base plate 33 to fix the mold base plate 33 and the cake base 34.

[0061] Step 11: The cutting slide 82 drives the cutting line 81 to move, so that the cutting line 81 is close to the mold base plate 33 to cut the cake base 34, thereby separating the mold base plate 33 from the cake base 34 and completing the demolding of the cake base 34.

[0062] In the twelfth step, when the vacuum suction cup 72 is reset, the vacuum suction cup 72 can remove the separated mold base plate 33 along with it;

[0063] Step 13: Manually remove the cake base 34 from the upper plate 22.

[0064] The lifting and lowering of the upper plate 22, the lifting and lowering of the tilting slide 44, the left and right movement of the stand 5, the lifting and lowering of the demolding slide 61, the lifting and lowering of the positioning slide 71, and the left and right movement of the cutting slide 82 are all driven by a screw mechanism. This screw mechanism includes a screw 83 and a screw motor 84 that drives the screw 83 to rotate. Specifically, for the left and right movement of the cutting slide 82, the screw 83 is mounted on the cutting frame 85 and threadedly connected to the cutting slide 82. Then, the screw motor 84 is mounted on the positioning slide 71, driving the screw 83 to rotate, thus moving the cutting slide 82. 2. The cutting line 81 is driven to move left and right along the lead screw 83 under the action of the thread force to cut the cake base 34. A smooth rod is set on another cutting frame 85. The smooth rod passes through another cutting slide 82 and plays a guiding role to ensure that the cutting line 81 moves smoothly. Similarly, the lifting and lowering of the upper plate 22, the lifting and lowering of the flip slide 44, the left and right movement of the stand 5, the lifting and lowering of the demolding slide 61, and the lifting and lowering of the positioning slide 71 are also driven by the lead screw 83 and the lead screw motor 84 set in the corresponding positions. At the same time, the smooth rod or slide rail and slider are set in the corresponding positions for guidance.

[0065] The above are merely specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be considered as infringing upon the protection scope of the present invention.

The fourth step involves moving the stand and raising and lowering the demolding slide to bring the demolding cone into contact with the edge of the cake base that is sticking to the mold cylinder, and then gently pressing the cake base downwards. The fifth step is to rotate the demolding shaft and the demolding cone. Since the demolding shaft is coaxial with the mold cylinder, the demolding cone rotates and presses against the surface of the cake base, separating all the edges of the cake base from the inner wall of the mold cylinder. Step 6: Once all the edges of the cake base have separated from the inner wall of the mold, reset the stand and demolding slide.
