Description

Technical Field

[0001] This application relates to the field of unmolding frozen cakes, and more particularly to a conveying heating device for unmolding cakes. Background Technology

[0002] Freezing or refrigerating cakes can extend their shelf life. However, when a cake is sold, it needs to be heated to separate it from the base and the metal ring, which is called unmolding.

[0003] Existing methods for removing cakes typically involve heating the steel ring on the cake tray, removing the ring, and then removing the cake from the tray. For example, there is a cake demolding machine with the publication number CN216315140U.

[0004] The aforementioned technology involves heating the steel ring first, which makes it inconvenient and prone to damaging the cake when transferring it from the base to the disposable paper cup. Summary of the Invention

[0005] In order to facilitate the transfer of cakes from the base to the paper tray without damaging the cakes, this application provides a cake demolding conveying heating device.

[0006] The present application provides a cake demolding conveying and heating device with the following technical solution.

[0007] A cake demolding conveying and heating device includes several moving conveyor belts arranged in parallel to move the cake forward, several electric heating plates located on the side of the moving conveyor belts along their length to heat the cake base, a synchronization plate detachably connected to the side plates of all the moving conveyor belts, and a lifting cylinder that moves the synchronization plate so that the height of the moving conveyor belts can be higher than the height of the electric heating plates.

[0008] By adopting the above technical solution, the conveyor belt moves to a position higher than the electric heating plate. Then, the frozen cake is placed on the conveyor belt and moved forward to the designated position. The conveyor belt then moves downward so that the cake base contacts the electric heating plate to heat and thaw the base. After thawing, the conveyor belt is raised to remove the heated cake and transport a new cake to be thawed to the designated position for thawing. The base is thawed first, and then the steel ring and cake are separated from the base so that the steel ring and cake can be transferred together to the paper tray. This method is less likely to damage the cake and is more convenient.

[0009] Optionally, at one end of the moving conveyor belt along its length, there is a fixed conveyor belt that is positioned to move the cake toward the moving conveyor belt, with one end of the moving conveyor belt located between the ends of two adjacent fixed conveyor belts.

[0010] By adopting the above technical solution, the length of the moving conveyor belt is reduced, the lifting mass of the lifting cylinder is reduced, and the stability is improved, so that the cake can be stably placed on the fixed conveyor belt.

[0011] Optionally, a flat plate is located at one end of the fixed conveyor belt near the moving conveyor belt, and two baffles are fixedly connected to the flat plate, which can abut against the steel ring of the cake.

[0012] By adopting the above technical solution, the circular steel ring can be smoothly inserted between the two stop posts, so that the position of the cake in the width direction of the moving conveyor belt remains stable and consistent.

[0013] Optionally, the synchronization plate is equipped with a stop cylinder that drives the flat plate to move so that the height of the stop column can be higher than the height of the fixed conveyor belt, and the side of the fixed conveyor belt is equipped with a front photoelectric sensor to detect the position of the cake so that the stop column can be raised in time.

[0014] By adopting the above technical solution, the baffle can rise in time to block the cake on the fixed conveyor belt, so that the subsequent moving conveyor belt can move the cake a predetermined distance to the designated position. After the moving conveyor belt completes the lifting, the baffle moves down again so that the moving conveyor belt can smoothly move the cake forward.

[0015] Optionally, the side plate of the fixed conveyor belt is equipped with a rear photoelectric sensor to detect the position of the cake abutting against the stop post so that the lifting cylinder can operate in a timely manner.

[0016] By adopting the above technical solution, the external controller can know the position of the cake at this time, so that after the previous cake is thawed, the conveyor belt can be raised directly to prevent the conveyor belt from being raised before the new cake is delivered to the position.

[0017] Optionally, all or part of the electric heating plates are slidably connected to a mounting bracket fixed at the same position, and the mounting bracket is detachably connected to a plate-moving cylinder that brings the electric heating plates closer together along the width direction of the moving conveyor belt.

[0018] By adopting the above technical solution, the electric heating plate is placed close to the cake base, making it less likely that the cake base will not be unable to fully defrost because a part of its area corresponds to the moving conveyor belt. This results in less adhesion between the base and the cake when the steel ring and the cake are separated from the base later.

[0019] Optionally, the electric heating plate includes a main plate with the widest width and several secondary plates located on both sides of the main plate. The position of the main plate is fixed, and each secondary plate is provided with a corresponding plate-moving cylinder.

[0020] By adopting the above technical solution, the motherboard area is made as large as possible to minimize the number of secondary boards that need to be moved, thereby reducing the complexity of the overall device and making the overall device less prone to problems during operation.

[0021] Optionally, the main board has raised strips formed on the upper length side near the secondary board and on the upper length side away from the main board, and the secondary board has a beveled surface that can fit into the raised strips on the upper length side near the main board.

[0022] By adopting the above technical solution, when the secondary plate moves toward the main plate, the bottom edge of the cake base may come into contact with the inclined side, making it less likely that the cake base will move along the width of the conveyor belt during the movement of the secondary plate, ensuring that the position of the cake is not easily deviated, so that the subsequent robotic arm can stably transfer the cake and steel ring from the base.

[0023] Optionally, the electric heating plate further includes a main fixing rod detachably connected to the main plate and a secondary sliding rod detachably connected to the secondary plate, the lengths of which can be changed.

[0024] By adopting the above technical solution, the height of the motherboard and secondary board can be adjusted accordingly.

[0025] Optionally, an elastic element is provided between the secondary slide bar and the shift plate cylinder to force the secondary slide bar to move toward the main fixed bar.

[0026] By adopting the above technical solution, the pressure between the secondary board and the main board is not easily excessive.

[0027] In summary, this application includes at least the following beneficial effects.

[0028] First, defrost the base, then separate the steel ring along with the cake from the base so that the steel ring and cake can be transferred together onto the paper cup, which is less likely to damage the cake and is more convenient. Attached Figure Description

[0034] The present application will be further described in detail below with reference to the accompanying drawings.

[0035] This application discloses a conveying and heating device for cake demolding, referring to... Figure 1 It includes a mounting frame 47 placed on the ground, and a fixed conveyor belt 41 is detachably connected to the upper part of the mounting frame 47. The length direction of the fixed conveyor belt 41 is consistent with the length direction of the mounting frame 47. Several fixed conveyor belts 41 are evenly spaced along their width direction, and the specific number can be three. The cake sent out from the freezing tunnel is transported forward on the fixed conveyor belt 41.

[0036] Reference Figure 1 and Figure 2 At one end of the fixed conveyor belt 41 located in the middle, there is a flat plate 42. Two baffles 46 are fixedly connected to the upper surface of the flat plate 42. The circular periphery of the cake steel ring and the base can be inserted between the two baffles 46 to fix the position of the cake in the width direction of the fixed conveyor belt 41. Above the mounting frame 47, there is a synchronization plate 3. The upper surface of the synchronization plate 3 is detachably connected to a baffle cylinder 43 whose power rod is detachably connected to the bottom surface of the flat plate 42. The side plate of the fixed conveyor belt 41 is detachably connected to a front photoelectric sensor 44. The transmitting and receiving parts of the front photoelectric sensor 44 are installed one-to-one on the two farthest side plates of the fixed conveyor belt 41, so that when the cake passes the front photoelectric sensor 44, the external controller can extend the power rod of the baffle cylinder 43 so that the cake can be blocked by the baffles 46.

[0037] Reference Figure 3A movable conveyor belt 1 is detachably connected to the upper surface of the synchronization plate 3. The length direction of the movable conveyor belt 1 is the same as that of the fixed conveyor belt 41. Several movable conveyor belts 1 are evenly spaced along their width direction, specifically four. One end of the length direction of each fixed conveyor belt 41 is located between two adjacent movable conveyor belts 1. A lifting cylinder 4 is detachably connected to the mounting bracket 47. The top of the power rod of the lifting cylinder 4 is detachably connected to the bottom surface of the synchronization plate 3. At the same time, a rear photoelectric sensor 45 is provided on the side plate of the fixed conveyor belt 41. When the cake comes into contact with the stop post 46, the cake is facing the rear photoelectric sensor 45. The external controller controls the lifting cylinder 4 to operate, so that the movable conveyor belt 1 rises. The rising height is 1 to 3 cm, so that the cake base is away from the fixed conveyor belt 41. Then the power rod of the stop cylinder 43 shortens, so that the stop post 46 no longer blocks the cake, so that the cake can be moved forward by the passive conveyor belt 1. Furthermore, the mounting bracket 47 is detachably connected to the hydraulic buffer 37 at each of the four corners of the synchronization plate 3, so that the synchronization plate 3 can fall slowly.

[0038] Reference Figure 2 and Figure 3 Between each of two adjacent moving conveyor belts 1, there is an electric heating plate 2. The electric heating plate 2 includes a main plate 49, a main fixing rod 34, two secondary plates 31, and two secondary sliding rods 35. The length direction of the main plate 49 and the secondary plates 31 is consistent with the length direction of the moving conveyor belt 1. The main plate 49 is located between the two secondary plates 31. The ends of the main plate 49 and the secondary plates 31 are aligned and close to the ends of the corresponding fixed conveyor belt 41. The cake is placed on the main plate 49 and the secondary plates 31 to heat the base, so that the steel ring and the cake can be removed from the base later. The main fixing rod 34 and the secondary sliding rods 35 are both vertical and adjustable in length. The main fixing rod 34 is detachably connected to the bottom surface of the main plate 49 and passes through the synchronization plate 3. The bottom end of the main fixing rod 34 is detachably connected to the mounting bracket 47. The secondary slide bar 35 is detachably connected to the bottom surface of the secondary plate 31. The secondary slide bar 35 passes through the synchronous plate 3. The bottom end of the secondary slide bar 35 is slidably connected to the mounting frame 47 along the width direction of the moving conveyor belt 1. The mounting frame 47 is detachably connected to two plate shifting cylinders 48. Each plate shifting cylinder 48 power rod and a corresponding secondary slide bar 35 are detachably connected to an elastic element 36. The elastic element 36 can be a spring buffer so that when the cake base is placed on the main plate 49 and the upper surface of the moving conveyor belt 1 is lower than the lower surface of the secondary plate 31, the two secondary plates 31 can move toward the main plate 49 so that the lower surface of the base is fully heated.

[0039] Reference Figure 2 and Figure 4Both secondary plates 31 have beveled edges 33 formed along their similar lengths on their upper surfaces. The closer the two beveled edges 33 are, the lower their height. This allows the cake bases to move along the beveled edges 33 even with minor deformation around their bottom surfaces, preventing them from being easily moved by the secondary plates 31. The main plate 49 has raised strips 32 formed on its surface near the beveled edges. The beveled edges 33 fit snugly against the raised strips 32, minimizing gaps between the main plate 49 and the secondary plates 31.

[0040] The implementation principle of a cake demolding conveyor heating device according to an embodiment of this application is as follows: When the fixed conveyor belt 41 conveys the cake past the front photoelectric sensor, the power rod of the stop cylinder 43 extends, so that when the cake moves to the end of the fixed conveyor belt 41, it can be blocked by the stop post 46. At this time, the cake is facing the rear photoelectric sensor 45. The power rod of the lifting cylinder 4 extends, so that the moving conveyor belt 1 and the cake are lifted. Then the power rod of the stop cylinder 43 retracts, so that the cake can be moved forward by the passive conveyor belt 1 to the designated position. Then the power rod of the lifting cylinder 4 retracts, and the cake falls onto the main plate 49 and the secondary plate 31. Then the power rod of the moving plate cylinder 48 extends, and the two secondary plates 31 move closer to the main plate 49 until the edge slope 33 is in contact with the protrusion 32 to heat the cake base.

[0041] When the heating time is set and a new cake is positioned directly in front of the rear photoelectric sensor 45, the lifting cylinder 4 extends its power rod, and the heated cake moves to the designated position. The robotic arm then separates the cake and steel ring from the base, and a new cake begins heating the base, continuously cycling through the process.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
