Description

Technical Field

[0001] The utility model relates to the technical field of candy cooling, in particular to a spiral cooling tower. Background Art

[0002] During the candy production process, the candy needs to be cooled and hardened before it can be packaged.

[0003] The cooling process of conventional candies is as follows: the candies to be cooled are placed on a conveyor chain, and then the conveyor chain passes through a cooling device, and cooling air is blown onto the candies through the cooling device, thereby achieving the purpose of cooling the candies.

[0004] In order to improve the cooling effect of candies, the cooling equipment is long and needs to continuously blow cooling air to the candies, resulting in a large footprint of the cooling equipment. To solve this problem, cooling air and other mechanisms are now installed on spiral cooling towers to reduce the footprint of the equipment. However, in the early stages of candy cooling, the candies are relatively soft and easily adhere to the conveyor chain. If the candies are placed on a tray and then the tray is placed on the conveyor chain, the cooling air can cause the tray and the conveyor chain to move relative to each other. In severe cases, the tray can fly out of the conveyor chain, affecting the cooling effect of the candies.

[0005] Therefore, how to design a bolted cooling tower for cooling candy has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] This embodiment provides a spiral cooling tower, which is mainly used for cooling candies, reduces the floor space occupied by the equipment, and improves the cooling effect of the candies.

[0027] like Figure 1 As shown, it comprises a spiral tower body 1, wherein a plurality of vertically arranged supporting legs 10 are fixedly provided on the side wall of the spiral tower body 1, wherein the supporting legs 10 are in contact with the ground for the spiral tower body 1 to stand upright.

[0028] Specifically, Figure 2 As shown, the spiral tower body 1 includes two parallel spiral rails 11, wherein the bottom wall of the spiral rails 11 is fixedly provided with a support plate 12 which is perpendicular to the two spiral rails 11, and the support foot 10 is fixedly installed on the side wall of the spiral rails 11, wherein the spiral rails 11 are also provided with a slide groove 111, wherein the slide groove 111 is slidably connected with a chain conveyor 22.

[0029] Among them, the spiral tower body 1 includes a feed port and a discharge port, wherein the chain conveyor belt 22 enters from the feed port of the spiral tower body 1 and flows out from the discharge port of the spiral tower body 1. Specifically, the chain conveyor belt 22 is connected end to end to form a closed loop, which is convenient for continuous transportation of materials.

[0030] It is worth noting that the moving direction of the chain conveyor 22 is as follows: Figure 1 Indicated by the direction of the arrow.

[0031] In order to achieve the end-to-end connection of the chain conveyor 22, in this embodiment, Figure 1 As shown, a supporting mechanism 2 is provided on the outer side of the spiral tower body 1, wherein a plurality of guide rollers 21 and a driving mechanism for driving the guide rollers 21 to rotate are rotatably provided on the supporting mechanism 2. Specifically, the chain conveyor 22 passes around the peripheral wall of the guide roller 21 to reverse the chain conveyor 22. The driving mechanism includes a driving motor 23, wherein the output shaft of the driving motor 23 is fixedly connected to one of the guide rollers 21.

[0032] The driving motor 23 is used to drive the chain conveyor 22 to move in the supporting mechanism 2 and the spiral tower body 1, thereby driving the candy to move.

[0033] In order to place the candies, the candies are placed on the chain conveyor 22. In this embodiment, as shown in FIG. Figure 1 and Figure 3 As shown, a plurality of material receiving trays 4 are provided on the chain conveyor 22 , wherein the material receiving trays 4 are used to place candies to prevent the candies from sticking to the chain conveyor 22 .

[0034] Since the chain conveyor 22 at the position of the spiral tower body 1 is in a spirally wound state, at this time, if the material tray 4 is directly fixed on the chain conveyor 22, the material tray 4 cannot rotate with the winding of the chain conveyor 22. When the chain conveyor 22 moves to the guide roller 21, the material tray 4 fixed on the chain conveyor 22 cannot be flipped, which will affect the transportation of the material tray 4.

[0035] Therefore, in this embodiment, if Figure 3 and Figure 7As shown, the chain conveyor 22 is fixed with a plurality of mounting seats 424, and the material receiving tray 4 includes a tray body 41 for carrying candies, a first rotating shaft 422 and a second rotating shaft 423. In this embodiment, the direction is redefined, and the direction is as follows: Figure 7 As shown in the plane coordinate system, the Z axis is perpendicular to the XOY plane, the first rotating shaft 422 is rotatably connected to the disk body 41, and the axis of the first rotating shaft 422 is parallel to the X axis, the second rotating shaft 423 is rotatably mounted on the mounting seat 424, and the second rotating shaft 423 can rotate around the Z axis, and the end wall of the second rotating shaft 423 is fixedly provided with a sleeve mounted on the outside of the first rotating shaft 422, wherein the sleeve is rotatably connected to the first rotating shaft 422.

[0036] Through the above-mentioned arrangement, when the chain conveyor 22 is spirally wound in the spiral tower body 1, as the angle of the chain conveyor 22 changes, the disc body 41 can swing around the second rotating shaft 423, wherein the maximum swing angle of the disc body 41 is α, thereby enabling the deflection of the disc body 41; when the disc body 41 moves to the position of the guide roller 21, the mounting seat 424 moves with the chain conveyor 22. Since the second rotating shaft 423 is installed on the mounting seat 424, the other end of the second rotating shaft 423 is rotatably connected to the first rotating shaft 422 through a bushing. At this time, the disc body 41 uses the second rotating shaft 423 and the mounting seat 424 as a fulcrum, and the disc body 41 flips over under the action of the first rotating shaft 422, thereby allowing the disc body 41 to bypass the guide roller 21.

[0037] In order to make the disk 41 parallel to the chain conveyor 22, in this embodiment, Figure 2 and Figure 7 As shown, a support column 425 is fixedly provided on the bottom wall of the disk body 41 , wherein the bottom of the support column 425 abuts against the top wall of the chain conveyor 22 , and the support column 425 can slide relative to the chain conveyor 22 .

[0038] In order to cool the candies stored in the tray 41 and improve the cooling effect of the candies, in this embodiment, Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, a plurality of cooling mechanisms 5 arranged along the length direction of the spiral track 11 are fixedly provided on the bottom wall of the spiral track 11 , and an air supply mechanism 3 is also provided which penetrates the spiral tower body 1 along the Z axis and provides cold air for the cooling mechanism 5 .

[0039] With the above arrangement, when the material tray 4 moves in the spiral tower body 1 along with the chain conveyor 22, the air supply mechanism 3 delivers cold air to the cooling mechanism 5, and then the cold air is blown onto the candies on the material tray 4 to achieve cooling of the candies.

[0040] Specifically, in this embodiment, if Figure 3 , Figure 4 and Figure 6 As shown, the cooling mechanism 5 includes a cooling cavity 51 and an air inlet 512 for providing cold air to the cooling cavity 51 . An air outlet 511 for blowing cold air toward the candies is also provided in the cooling cavity 51 , wherein the air supply mechanism 3 is connected to the air inlet 512 .

[0041] Through the above arrangement, the air supply mechanism 3 provides cold air to the cooling chamber 51 through the air inlet 512 , and then the cold air flows out from the air outlet 511 , thereby achieving cooling of the material.

[0042] Since a plurality of cooling mechanisms 5 are provided at the bottom of the spiral track 11, in order to provide cold air to the cooling mechanisms 5, in this embodiment, Figure 5 As shown, the air supply mechanism 3 includes a main air supply pipe 31, an auxiliary air supply pipe 32 and an air supply branch pipe 33, wherein the main air supply pipe 31 passes through the spiral tower body 1, and the auxiliary air supply pipe 32 is provided with a plurality of auxiliary air supply pipes 32 and distributed along the axial direction of the main air supply pipe 31, and the auxiliary air supply pipe 32 is annular, one end of the air supply branch pipe 33 is connected to the main air supply pipe 31, and the other end of the air supply branch pipe 33 is connected to the auxiliary air supply pipe 32, and the auxiliary air supply pipe 32 is also provided with a plurality of connecting pipes 321, wherein the connecting pipe 321 is connected to the air inlet 512, so as to lead the cold air from the outside to the cooling chamber 51.

[0043] Since there are gaps between the material trays 4 on the chain conveyor 22, if the cold air in the cooling chamber 51 continues to flow out from the air outlet 511, it will cause a waste of resources. Figure 6 As shown, the cooling mechanism 5 includes a lifting plate 52, a compression spring 53 and a blocking block 521 located in the cooling chamber 51, wherein the blocking block 521 is fixedly mounted on the lifting plate 52, one end of the compression spring 53 abuts against the lifting plate 52, and the other end of the compression spring 53 abuts against the inner wall of the cooling chamber 51. When the material tray 4 moves away from the cooling mechanism 5, the compression spring 53 pushes the lifting plate 52 to make the blocking block 521 plugged into the air outlet 511 to prevent the cold air in the cooling chamber 51 from flowing out. When the material tray 4 is located directly below the cooling mechanism 5, the lifting plate 52 compresses the compression spring 53, the blocking block 521 moves out from the air outlet 511, the air outlet 511 is opened, and the cold air blows toward the material in the material tray 4 to achieve cooling of the material.

[0044] In order to open the air outlet 511, in this embodiment, Figure 4 and Figure 6As shown, the top wall of the disk body 41 is fixedly provided with a push bar 42 extending upward, and the bottom wall of the lifting plate 52 is fixedly provided with a push rod 522 extending out of the cooling chamber 51. When the material tray 4 moves to the bottom of the cooling mechanism 5 under the action of the chain conveyor 22, the push bar 42 abuts against the bottom wall of the push rod 522, thereby pushing the push rod 522 into the cooling chamber 51. At this time, the lifting plate 52 moves upward, the air outlet 511 opens, and cold air flows out, thereby realizing the cooling of the material; when the material tray 4 moves away from the bottom of the cooling mechanism 5, the lifting plate 52 moves downward under the thrust of the compression spring 53, and the air outlet 511 is re-blocked, thereby reducing energy waste.

[0045] In order to facilitate the upward pushing of the push rod 522, in the present embodiment, a second curved surface 5221 is provided at the bottom of the push rod 522, and a first curved surface 421 is provided on the push strip 42. When the push rod 522 contacts the push strip 42, the first curved surface 421 contacts the second curved surface 5221, thereby facilitating the pushing of the push rod 522 and smoothly opening the air outlet 511.

[0046] It is worth noting that the first arc surface 421 is located on the push bar 42 and on the side where the material receiving tray 4 moves forward.

[0047] Due to the special structure of the spiral tower body 1, the chain conveyor 22 will deflect when driving the material tray 4 forward. In order to ensure the pushing effect of the pushing bar 42 on the pushing rod 522, in this embodiment, Figure 3 and Figure 7 As shown, the cross section of the push strip 42 is S-shaped.

[0048] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
