[0043] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment 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. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0044] Stick-style cold drink products are mass-produced through a long cylinder line production system.

[0045] In the related art, the long cylinder line production system has a freezing tank and a product mold, wherein a freezing medium is provided in the freezing tank, the product mold is located in the freezing tank and completes heat exchange with the freezing medium, and the freezing medium is used to freeze and shape the material in the mold.

[0046] However, the cooling medium can easily enter the mold and contaminate the material, resulting in a decrease in the yield rate of the product.

[0047] In order to overcome the defects in the prior art, the present application provides a long cylinder line production system, including a freezing tank, a mold and an observation component. The mold has a cavity for accommodating a material, and the mold is at least partially located in the freezing tank. The cooling medium flows in the freezing tank and conducts heat through the cavity wall of the mold and the material to freeze and shape the material. The observation component is located at the top of the freezing tank in the vertical direction, and the observation component includes a light-emitting component, which emits light to the mold. In this way, the light-emitting component illuminates the mold so that the staff can observe the mold and promptly deal with the mold contaminated by the cooling medium, thereby improving the yield rate of the product.

[0048] The content of the utility model will be described in detail below with reference to the accompanying drawings so that those skilled in the art can understand the content of the utility model more clearly and in detail.

[0049] Figure 1 A schematic diagram of a long cylinder line production system provided in an embodiment of the present application. Figure 2 for Figure 1 A partial enlarged view of part A. Figure 3 A schematic diagram of an observation component in a long cylinder line production system provided in an embodiment of the present application.

[0050] like Figure 1-Figure 3 As shown, this embodiment provides a long cylinder line production system 100, including a freezing tank 110, a mold 120 and an observation component 130, the mold 120 has a cavity 121 for accommodating a material, and the mold 120 is at least partially located in the freezing tank 110; the freezing medium flows in the freezing tank 110 and is thermally connected to the material through the cavity wall of the mold 120.

[0051] The observation assembly 130 is located at the top of the freezing tank 110 along the vertical direction (Z direction), and the observation assembly 130 includes a light emitting member 131 , and the light emitting member 131 emits light toward the mold 120 .

[0052] The long cylinder line production system 100 provided in this embodiment illuminates the mold 120 through the light-emitting element 131, so that the staff can promptly find the mold 120 contaminated by the cooling medium and quickly process the contaminated mold 120, thereby improving the product yield.

[0053] Exemplarily, the freezing tank 110 can be placed on the ground through a support structure. The mold 120 is located in the freezing tank 110, and the portion of the mold 120 in the freezing tank 110 is in contact with the cooling medium. In this way, the cooling medium and the cavity wall of the cavity 121 of the mold 120 are thermally conductive. When the material is put into the cavity 121 of the mold 120, the cooling medium can cool the material through the cavity wall of the mold 120, and the material can be frozen and shaped.

[0054] It should be noted that the material in this embodiment is the raw material of the cold drink product, and the cooling medium is the calcium chloride solution.

[0055] It is understandable that the mold 120 is prone to damage after long-term use, and leaks are formed on the mold 120. The cooling medium can easily enter the cavity 121 through the leaks to contaminate the mold 120, and further contaminate the material in the mold 120, resulting in unqualified products. During the freezing process, the water level of the cooling medium will inevitably overflow the mold 120 and the connection seam of the mold 120, and the cooling medium will enter the mold 120. Therefore, in order to facilitate the staff to observe the mold 120 and the cavity 121 of the mold 120, the mold 120 contaminated by the cooling medium is promptly removed and cleaned in time, thereby improving the yield rate of the product. The observation component 130 in this embodiment is arranged at the top of the freezing tank 110 along the vertical direction (Z direction).

[0056] The observation assembly 130 includes a light emitting member 131, and the light emitting member 131 emits light to the mold 120. It can be understood that the light emitting member 131 shines on the mold 120 and can illuminate the cavity 121 of the mold 120. In this way, during the inspection process, the staff can promptly find the molds 120 and materials contaminated by the cooling medium, quickly remove and replace them, so as to inspect and repair these molds 120. In this way, the production efficiency and yield rate of the product can be guaranteed.

[0057] It should be noted that the light emitting element 131 in this embodiment may be a lamp tube, or may be a lamp having any shape or structure and having a lighting function.

[0058] Combined with the above parts, the structure of the light emitting member 131 has diversity. As a possible implementation, the light emitting member 131 includes a light emitting portion 1311, the light emitting portion 1311 extends along the first direction (Y direction), the light emitting portion 1311 is at least partially light-transmissive, and emits light toward the mold 120; the first direction (Y direction) and the vertical direction (Z direction) intersect.

[0059] It can be understood that the light-emitting component 131 includes a light-emitting portion 1311, and the light-emitting portion 1311 is at least partially translucent on the side facing the mold 120. In this way, light is emitted to the mold 120 through the light-emitting portion 1311, which makes it convenient for the staff to check and judge the working status of the mold 120, and to promptly remove and repair the molds 120 contaminated by the cooling medium.

[0060] The light emitting part 1311 in this embodiment is along the first direction (Y direction), and the first direction (Y direction) intersects with the vertical direction (Z direction). It is not difficult to understand that the extension direction of the light emitting part 1311 intersects with the vertical direction (Z direction), that is, the extension direction (Y direction) of the light emitting part 1311 and the vertical direction (Z direction) have an angle, which can be 90°. At this time, the light emitting part 1311 and the freezing tank 110 are opposite to each other along the vertical direction (Z direction), and the light emitting part 1311 emits light from the mold 120 located in the freezing tank 110 along the vertical direction (Z direction).

[0061] Alternatively, the angle between the extension direction (Y direction) of the light-emitting portion 1311 and the vertical direction (Z direction) is an obtuse angle, the light-emitting portion 1311 is located above the freezing tank 110, and the light-emitting portion 1311 is inclined relative to the freezing tank 110. The light-emitting portion 1311 can still emit light to the mold 120 to facilitate the staff to observe the mold 120.

[0062] Exemplarily, the light emitting member 131 further includes a support portion 1312, which extends in the vertical direction (Z direction) and is connected to the light emitting portion 1311; the support portion 1312 drives the light emitting portion 1311 to rotate relative to the freezing tank 110 around the rotation axis; the rotation axis is in the vertical direction (Z direction). In this way, the light emitting portion 1311 rotates relative to the freezing tank 110, and the light irradiation range of the light emitting portion 1311 increases. At the same time, the light emitting portion 1311 can be rotated to the outside of the freezing tank 110 to facilitate the demolding operation after the material is frozen and shaped.

[0063] It can be understood that the first end of the support portion 1312 can be connected to the ground or other component platforms of the long cylinder line production system 100, the second end of the support portion 1312 extends along the vertical direction (Z direction), and the second end of the support portion 1312 is connected to the light-emitting portion 1311 to support the light-emitting portion 1311 to be located above the freezing tank 110 along the vertical direction (Z direction).

[0064] Furthermore, the support member rotates around the rotation axis, thereby driving the light-emitting member 131 to rotate around the rotation axis relative to the freezing tank 110.

[0065] In this way, the rotation of the light-emitting part 1311 can adjust the relative position between the light-emitting part 1311 and the freezing tank 110, and correspondingly, the relative position between the light-emitting part 1311 and the mold 120 is also changed, so that the light emitted by the light-emitting part 131 at a certain position can illuminate more molds 120, thereby increasing the observation range of the staff, thereby improving the efficiency of removing contaminated molds 120, and further improving the productivity and yield rate of the product.

[0066] On the basis of the above-mentioned embodiment, the light emitting element 131 has a base 1313 . The base 1313 is disposed at one end of the supporting portion 1312 away from the light emitting portion 1311 . The supporting portion 1312 rotates around the rotation axis relative to the base 1313 .

[0067] The base 1313 in this embodiment can be connected to the ground or the platform of other components in the long cylinder line production system 100. The support part 1312 rotates around the rotation axis relative to the base 1313, and the support part 1312 can drive the light-emitting part 1311 to rotate around the rotation axis relative to the freezing tank 110.

[0068] Exemplarily, the support portion 1312 has a rotating cavity, which is located at one end of the support portion 1312 facing the base 1313, the rotating axis of the rotating cavity is along the rotation axis, and the end of the support portion 1312 facing the base 1313 has an opening connected to the rotating cavity; the base 1313 has a plug-in portion, and the plug-in portion is at least partially located in the rotating cavity through the opening. In this way, through the connection between the base 1313 and the rotating cavity of the support portion 1312, the support portion 1312 can rotate relative to the base 1313 around the rotation axis.

[0069] It can be understood that the support portion 1312 has a rotating cavity at one end facing the base 1313, the rotating cavity extends along the vertical direction (Z direction), and the rotating axis of the rotating cavity is along the rotation axis, that is, the rotating axis of the rotating cavity is along the vertical direction (Z direction).

[0070] The base 1313 is provided with a plug-in portion on one side facing the support portion 1312, and the structures of the plug-in portion and the rotating cavity match each other. It can be understood that the plug-in portion is located in the rotating cavity through the opening of the support portion 1312 facing the base 1313. Under the action of external force, the support portion 1312 can drive the light-emitting portion 1311 to rotate around the rotation axis through the relative rotation between the cavity wall of the rotating cavity and the plug-in portion.

[0071] In some embodiments, the observation assembly 130 also includes an observation stool 132, and the light-emitting member 131 is arranged on the observation stool 132 along the vertical direction (Z direction); the observation stool 132 is movably arranged along the second direction (X direction) relative to the freezing tank 110; the second direction (X direction) is parallel to the length direction of the freezing tank 110.

[0072] It can be understood that the light-emitting component 131 is connected to the observation stool 132. The staff can sit on the observation stool 132 to adjust the rotation angle of the light-emitting component 131 relative to the freezing tank 110 around the rotation axis, so that the staff can better observe the working condition of the mold 120 to ensure that the mold 120 is not contaminated by the freezing medium, or to promptly discover the contaminated mold 120 and remove it from the freezing tank 110, thereby ensuring the productivity and yield rate of the product.

[0073] It should be noted that in this embodiment, the height of the observation stool 132 along the vertical direction (Z direction) is higher than the freezing tank 110, and the observation stool 132 moves relative to the freezing tank 110 along the second direction (X direction), and the second direction (X direction) is along the length direction (X direction) of the freezing tank 110. In other words, the observation stool 132 moves along the length direction of the freezing tank 110. The staff expands the observation range of the mold 120 in the freezing tank 110 through the moving observation stool 132. In this way, the mold 120 contaminated by the freezing medium can be quickly removed, thereby improving the productivity and yield rate of the product. Furthermore, the staff can complete the corresponding work by sitting on the observation stool 132, which can reduce the labor intensity of the staff.

[0074] In this embodiment, the observation bench 132 can be arranged on both sides of the freezing tank 110 in the width direction, or only on one side of the two sides of the freezing tank 110 in the width direction, and this section does not specifically limit this. Regardless of which side of the freezing tank 110 the observation bench 132 is arranged on, the seat direction of the observation bench 132 must face the freezing tank 110 so that the mold 120 in the freezing tank 110 falls within the field of vision of the staff.

[0075] Exemplarily, the long cylinder line production system 100 further includes a slide rail (not shown in the figure), the slide rail extends along the second direction (X direction), the bottom of the observation stool 132 is connected to the slide rail, and the observation stool 132 moves via the slide rail.

[0076] In some specific embodiments, the slide rail is disposed on the side of the freezing tank 110 in the width direction, and the slide rail extends along the second direction (X direction), that is, the slide rail extends along the length direction of the freezing tank 110. The bottom of the observation stool 132 is connected to the slide rail, and the observation stool 132 moves along the second direction (X direction) through the slide rail.

[0077] In this embodiment, the staff can apply external force to the observation stool 132 to drive the observation stool 132 to move along the second direction (X direction) through the slide rail. Of course, the long cylinder line production system 100 can also include a drive component, the drive component is electrically connected to the slide rail or the observation stool 132, and the drive component provides a mechanical driving force to enable the observation stool 132 to move through the slide rail.

[0078] In some embodiments, the slide rail has a groove extending along the second direction (X direction); a roller 1321 is disposed at the bottom of the observation stool 132, and the roller 1321 is located in the groove. In this way, the slide rail is relatively fixed, and the roller 1321 rolls along the slide rail to realize the movement of the observation stool 132 along the second direction (X direction).

[0079] Furthermore, there are two slide rails, which are spaced apart at both ends of the freezing tank 110 along the length direction of the freezing tank 110; the observation stool 132 spans across both ends of the freezing tank 110 along the length direction of the freezing tank 110 and is connected to the slide rails.

[0080] The observation stool 132 in this embodiment extends along the length direction of the freezing tank 110, and is arranged on the top of the freezing tank 110 along the vertical direction (Z direction), and the bottom of the observation stool 132 is connected to the slide rail along the vertical direction (Z direction).

[0081] Furthermore, there are two slide rails in this embodiment, both of which extend along the length direction of the freezing tank 110. The bottom of the observation bench 132 is connected to the slide rails so as to move along the second direction (X direction) through the slide rails, thereby driving the light-emitting member 131 to move. In this way, the staff can observe the mold 120 in the freezing tank 110 along the length direction of the freezing tank 110 on the observation bench 132. Alternatively, multiple staff members can observe the mold 120 in the freezing tank 110 on the observation bench 132 at the same time, thereby improving the efficiency of observation, further ensuring the production of the product, and thus improving the productivity and yield rate of the product.

[0082] Of course, a roller 1321 is provided at the bottom of the observation stool 132. The roller 1321 and the slide rail are correspondingly provided. The roller 1321 is located inside the slide rail. The roller 1321 rolls to drive the observation stool 132 to move along the length direction (X direction) of the freezing tank 110.

[0083] It is understandable that when the observation stool 132 moves, the staff can observe a relatively increased number of molds 120 in the freezing tank 110, and can quickly and widely identify the molds 120 contaminated by the freezing medium and respond in time, thereby improving the product yield.

[0084] Of course, in some embodiments, the mold 120 is movable relative to the freezing tank 110 along the length direction of the freezing tank 110. In this way, the staff can observe the mold 120 in the freezing tank 110 at a relatively fixed position.

[0085] It can be understood that the mold 120 moves relative to the freezing tank 110 along the length direction (X direction) of the freezing tank 110, and the frozen and shaped material can flow with the mold 120 to the next station of the long cylinder line production system 100 for demolding. During the movement of the mold 120, no matter where the observation component 130 is located relative to the freezing tank 110, the staff can observe the working status of all the molds 120 in the freezing tank 110, so as to detect the mold 120 contaminated by the cooling medium to ensure the product yield.

[0086] The long cylinder line production system provided in this embodiment includes a freezing tank, a mold and an observation component. The mold has a cavity for accommodating materials, and the mold is at least partially located in the freezing tank; the freezing medium flows in the freezing tank and is thermally connected to the materials through the cavity wall of the mold; the observation component is located at the top of the freezing tank in the vertical direction, and the observation component includes a light-emitting component, which emits light to the mold. Through such a setting, the staff can promptly find the mold contaminated by the cooling medium, and quickly deal with the contaminated mold, thereby improving the product yield.
