Description

Technical Field

[0001] This invention relates to the field of ice cream cone production technology, and more particularly to an ice cream cone surface spraying and filling production line. Background Technology

[0002] In the industrial production process of ice cream cones, the coating of the cone surface (such as chocolate coating on the outer wall and moisture-proof coating on the inner wall) and the filling of ice cream are key steps to improve the product's taste and added value. These two steps place extremely high demands on the continuity of production equipment, the stability of the cone's posture, and operational safety. However, existing production lines still have many technical pain points in practical applications.

[0003] Currently, the coating and filling of egg cones mostly adopt a segmented production model. First, the egg cones are transported to the coating station for surface treatment via a conveyor, and then transferred to the filling station for filling. However, the double-sided coating of the inner and outer surfaces of the egg cone currently relies entirely on manual operation. This segmented production combined with manual coating not only increases equipment footprint and labor costs, but also makes the egg cone's posture highly susceptible to deviation during manual operation, leading to overflow of filling or scratches on the coating during subsequent filling, affecting product quality. Furthermore, in the coating stage, manual operation makes it difficult to achieve simultaneous and precise coating of the inner and outer surfaces of the egg cone. Because the egg cone has a conical structure, coating the outer wall requires the egg cone to be kept vertical to ensure a uniform coating, while coating the inner wall requires flipping or tilting the egg cone. Manual flipping can easily cause the egg cone to wobble, resulting in uneven coating thickness; and if the posture cannot be quickly stabilized after flipping, it further prolongs the coating cycle, restricting production efficiency.

[0004] Therefore, developing an integrated production line capable of continuous conveying, stable clamping, precise flipping, synchronous spraying, and efficient material handling of egg cones has become the key to solving the current technical challenges. Summary of the Invention

[0005] The purpose of this invention is to solve the problem in existing production line technology where it is difficult to achieve synchronous and precise spraying of the inner and outer surfaces of ice cream cones by manual operation. It provides an ice cream cone surface spraying and filling production line, which uses a mechanical adaptation structure of limiting sliding pillars set at the four corners of the moving parts and the flipping slide on the first flipping plate to forcibly guide the cone to move along a predetermined trajectory during the flipping process, without redundancy of degrees of freedom, so as to achieve synchronous and precise spraying.

[0006] To achieve the above objectives, the present invention provides an ice cream cone surface spraying and filling production line, including a conveyor frame, a limiting slide plate on the conveyor frame, a conveyor chain on the inner side of the limiting slide plate, and multiple sets of clamping components for clamping ice cream cones arranged at equal intervals on the conveyor chain. Both ends of the clamping components move on the limiting slide plate via moving parts. A fixed frame is installed on the conveyor frame, and a first spraying part for spraying the outer surface of the ice cream cone and a second spraying part for spraying the inner surface of the ice cream cone are installed inside the fixed frame. A first flipping plate for flipping the moving parts is provided below the fixed frame, and the first flipping plate is installed on the limiting slide plate.

[0007] Each of the four corners of the moving part is provided with a limiting slide post, and the first flip plate is provided with a flip slide that is adapted to the limiting slide post.

[0008] As a further description of the above technical solution: a feeding rack is provided on one side of the fixed frame, an injection device is provided on the other side of the fixed frame, a feeding assembly is provided on the feeding rack, a lifting assembly for driving the clamping assembly to rise and fall is provided below the feeding assembly, and a second flip plate is provided below the injection device and mounted on the limiting slide plate.

[0009] As a further description of the above technical solution: a receiving component is provided at the unloading end on one side of the conveyor frame, and an arc-shaped limiting plate is provided above the receiving component and mounted on the conveyor frame. The arc-shaped limiting plate is provided with a limiting flow channel for keeping the clamping component from flipping over.

[0010] As a further description of the above technical solution: the clamping assembly includes two clamping plates, which are engaged with the conveyor chain via drive columns. Two opening and closing clamping columns are rotatably connected between the two clamping plates. Opening and closing plates are fixed to the ends of the two opening and closing clamping columns. A connecting rod is provided between adjacent opening and closing plates, and a spring is sleeved on the connecting rod.

[0011] As a further description of the above technical solution: the feeding assembly includes an upper clamping member and a lower clamping member. The upper clamping member is connected to the upper surface of the feeding frame, and the lower clamping member is connected to the lower surface of the feeding frame. The feeding frame has multiple egg dropping holes.

[0012] As a further description of the above technical solution: the upper clamping member and the lower clamping member have the same structure. The upper clamping member includes a pushing member, which drives multiple clamping units to move through a pushing rod.

[0013] As a further description of the above technical solution: the lifting assembly includes a lifting cylinder, the lower end of which is connected to a lifting plate via a connector, and the lifting plate is used to drive the moving parts and the clamping assembly to rise and fall.

[0014] As a further description of the above technical solution: the receiving component includes a base, a collection box is provided on the base, the collection box has multiple placement holes, and a pusher is provided below the collection box.

[0015] As a further description of the above technical solution: a pressure plate is provided below the unloading rack.

[0016] As a further description of the above technical solution: an upper pressure plate is provided at the bottom of the arc-shaped limiting plate.

[0017] The above technical solution has the following advantages or beneficial effects:

[0018] This invention achieves seamless connection between vertical spraying on the outer surface of the cone and flipping spraying on the inner surface by linearly integrating a first spraying component and a second spraying component within a fixed frame on a single conveyor chain, in conjunction with a first flipping plate located below the fixed frame. This eliminates the risk of coating abrasion and posture deviation caused by segmented transfer. Through the mechanical adaptation structure of the limiting sliding posts at the four corners of the moving component and the flipping slide on the first flipping plate, the cone is forcibly guided to move along a predetermined trajectory during the flipping process. There is no redundancy in the degree of freedom. The slide-type flipping mechanism and the linear conveyor chain ensure that the flipping process does not require additional driving energy, reducing energy consumption and maintenance costs.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] In the description of this invention, it should be noted that the terms "vertical," "upper," "lower," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0035] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0036] like Figure 1-12 As shown, an ice cream cone surface spraying and filling production line of the present invention includes a conveyor frame 1, a limiting slide plate 2 is provided on the conveyor frame 1, a conveyor chain 3 is provided inside the limiting slide plate 2, and multiple sets of clamping components 4 for clamping ice cream cones are provided at equal intervals on the conveyor chain 3. Both ends of the clamping components 4 move on the limiting slide plate 2 through moving parts 5. A fixed frame 6 is installed on the conveyor frame 1. A first spraying part 7 for spraying the outer surface of the ice cream cone and a second spraying part 8 for spraying the inner surface of the ice cream cone are installed inside the fixed frame 6. A first flipping plate 9 for flipping the moving part 5 is provided below the fixed frame 6. The first flipping plate 9 is installed on the limiting slide plate 2. Limiting slide posts 51 are provided at each of the four corners of the moving part 5. A flipping slide 91 adapted to the limiting slide posts 51 is provided on the first flipping plate 9.

[0037] In the technical solution of this invention, a first spraying component 7 and a second spraying component 8 are linearly integrated within a fixed frame 6 on a single conveyor chain 3. Together with a first flipping plate 9 set below the fixed frame 6, a seamless connection is achieved between vertical spraying on the outer surface of the cone and flipping spraying on the inner surface, eliminating the risk of coating scratches and posture deviation caused by segmented transfer. Through the mechanical adaptation structure of the limiting sliding columns 51 set at the four corners of the moving component 5 and the flipping slide 91 on the first flipping plate 9, the cone is forcibly guided to move along a predetermined trajectory during the flipping process. There is no redundancy in the degree of freedom, ensuring the uniformity of the coating thickness on the inner wall. The slide-type flipping mechanism and the linear conveyor chain 3 realize that the flipping process does not require additional driving energy, reducing energy consumption and maintenance costs. By using the sliding column-slide limit flipping as the core, a single station can achieve high-precision double-sided spraying of the cone.

[0038] like Figure 1 and Figure 2 As shown, a feeding rack 10 is provided on one side of the fixed frame 6, and a filling device 11 is provided on the other side of the fixed frame 6. A feeding assembly 12 is provided on the feeding rack 10, and a lifting assembly 13 for driving the clamping assembly 4 to rise and fall is provided below the feeding assembly 12. A second flipping plate 14 is installed on the limiting slide plate 2 below the filling device 11.

[0039] Specifically, the unloading rack 10 and the filling device 11 correspond to the upstream and downstream stations of the fixed frame 6, respectively. With the continuous conveying of the conveyor chain 3, the egg cartridges, after being loaded from the unloading component 12, can be directly conveyed to the fixed frame 6 for spraying via the conveyor chain 3. After spraying, they can directly enter the filling device 11 for filling without additional transfer, eliminating the independent transfer links between processes in traditional segmented production, significantly shortening process intervals, improving overall production cycle time, and reducing the overall equipment footprint. The lifting component 13 can drive the clamping component 4 to rise and fall, precisely aligning it with the unloading position of the unloading component 12. This ensures that the egg cartridges are stably received by the clamping component 4 after being released from the unloading component 12, avoiding the problem of egg cartridges falling or shifting in posture due to misalignment between the clamping component and the unloading position during traditional loading. This provides a pre-guarantee for the stable operation of subsequent spraying and filling processes, further improving the reliability of the production process.

[0040] The second flipping plate 14 has the same structure as the first flipping plate 9. The second flipping plate 14 adopts the same structure as the first flipping plate 9. It achieves posture adjustment through the same "limiting slide column-flipping slide" matching method as the first flipping plate 9. On the one hand, it can stably flip the sprayed egg cone to the posture suitable for filling, ensuring accurate filling and avoiding overflow during filling. On the other hand, the same structural design ensures the consistency and stability of the flipping action, reduces the risk of posture deviation caused by the adaptation difference of different flipping mechanisms, and reduces the types of equipment parts, which facilitates standardized production and maintenance.

[0041] like Figure 2 and Figure 7 As shown, a receiving component 15 is provided on the unloading end of one side of the conveyor frame 1. An arc-shaped limiting plate 16 is installed on the conveyor frame 1 above the receiving component 15. The arc-shaped limiting plate 16 is provided with a limiting flow channel 161 to keep the clamping component 4 from flipping. The limiting flow channel 161 on the arc-shaped limiting plate 16 can limit the moving part 5, so that the moving part 5 can move horizontally and vertically without rotating, so that the ice cream cone held by the clamping component 4 falls vertically and avoids the ice cream cone from flipping after being filled.

[0042] like Figure 1 and Figure 8As shown, the clamping assembly 4 includes two clamping plates 41. The clamping plates 41 are engaged with the conveyor chain 3 via a drive column 42. Two opening and closing clamping columns 43 are rotatably connected between the two clamping plates 41. Opening and closing plates 44 are fixed at the ends of the two opening and closing clamping columns 43. A connecting rod 45 is provided between adjacent opening and closing plates 44. A spring 46 is sleeved on the connecting rod 45. When the pressure plate on the conveyor line presses down, the pressure is transmitted to the opening and closing plates 44 at both ends through the connecting rod 45, forcing the two opening and closing plates 44 to move closer to each other. At this time, the spring 46 is compressed and stores elastic potential energy. The rotation of the opening and closing plates 44 will directly drive the opening and closing clamping columns 43 to "close" synchronously, thereby allowing the two opening and closing clamping columns 43 to complete the clamping of the cone. When the other pressure plate on the conveyor line is pushed up, the spring 46 will release elastic potential energy and generate a restoring thrust, pushing the two opening and closing plates 44 away from each other, driving the two opening and closing clamping columns 43 to "open", thereby allowing the two opening and closing clamping columns 43 to complete the release of the cone.

[0043] like Figure 9 and Figure 10 As shown, the feeding assembly 12 includes an upper clamping member 121 and a lower clamping member 122. The upper clamping member 121 is connected to the upper surface of the feeding rack 10, and the lower clamping member 122 is connected to the lower surface of the feeding rack 10. The feeding rack 10 has multiple egg drop holes 101. The lower clamping member 122 can hold the bottom egg cone of the stacked egg cone group, and the upper clamping member 121 can hold the second to last egg cone of the stacked egg cone group. When the lower clamping member 122 is released, the bottom egg cone falls due to its own gravity, while the upper egg cone is firmly fixed by the upper clamping member 121 to prevent it from falling together. Through the hierarchical control of "fixing the top first and then releasing the bottom", the independent release of a single egg cone is achieved.

[0044] Specifically, multiple vertically stacked egg cones are placed in the egg drop chute above the feeding rack 10. The bottom egg cone is limited by the lower clamping member 122 to prevent it from falling. The second to last egg cone is clamped by the upper clamping member 121. At the same time, the lower clamping member 122 is released, so that the last egg cone falls onto the clamping component 4. The last egg cone falls to the lower clamping member 122 by clamping it with the lower clamping member 122 and releasing the upper clamping member 121, thus achieving continuous feeding.

[0045] like Figure 9 and Figure 11 As shown, the upper clamping member 121 and the lower clamping member 122 have the same structure. The upper clamping member 121 includes a pusher 1211, which drives multiple clamping units 1213 to open and close via a push rod 1212. By moving the push rod 1212 via the pusher 1211, all clamping units 1213 can be driven to move synchronously (clamp or release), resulting in high consistency of action and avoiding production stoppages caused by jamming of a single unit.

[0046] Specifically, the clamping unit 1213 consists of multiple push plates, forming symmetrically distributed multiple contact points, distributing the clamping force to multiple positions on the outer wall of the egg cone, thus avoiding excessive local stress.

[0047] like Figure 9 and Figure 10 As shown, the material lifting assembly 13 includes a lifting cylinder 131. The lower end of the lifting cylinder 131 is connected to the lifting plate 133 via a connector 132. The lifting plate 133 is used to drive the moving part 5 and the clamping assembly 4 to rise and fall. When the lifting cylinder 131 works, the lifting plate 133 can be driven to rise via the connector 132. The rise of the lifting plate 133 will drive the moving part 5 and the clamping assembly 4 to rise. Together with the material unloading assembly 12 and the pressure plate 17, the ice cream cone can be clamped and transferred.

[0048] like Figure 1 and Figure 12 As shown, the receiving component 15 includes a base 151, a collection box 152 is provided on the base 151, a plurality of placement holes 153 are provided on the collection box 152, and a pusher 154 is provided below the collection box 152; the ice cream cones that have been filled can be received by the multiple placement holes 153 on the collection box 152 as they fall through the arc-shaped limiting plate 16 and are released by the clamping component 4; the pusher 154 can drive the collection box 152 to step on the base 151, so that the collection box 152 can continuously receive the ice cream cones that have been filled.

[0049] like Figure 7 and Figure 10 As shown, a lower pressure plate 17 is provided below the unloading rack 10, and an upper pressure plate 18 is provided at the bottom of the arc-shaped limiting plate 16. The lifting assembly 13 drives the moving part 5 and the clamping assembly 4 to rise. During the rising of the clamping assembly 4, the upper part of the connecting rod 45 and the spring 46 between the two opening and closing plates 44 will touch the lower pressure plate 17, causing the two opening and closing plates 44 to close together, thereby clamping the ice cream cones falling from the unloading assembly 12. During the falling of the clamping assembly 4 past the arc-shaped limiting plate 16, the upper pressure plate 18 will strike the lower part of the connecting rod 45 and the spring 46 between the two opening and closing plates 44, causing the two opening and closing clamping posts 43 to open, allowing the ice cream cones clamped on the clamping assembly 4 to fall into the placement holes 153 opened on the collection box 152 for collection. At the same time, the pushing part 154 drives the collection box 152 to move, so that subsequent placement holes 153 can be continuously placed.

[0050] The system uses spring 46 and connecting rod 45 as the core driving components. The pressure plate completes the cycle of "pressing down-clamping" and "lifting up-releasing". The restoring force of spring 46 is evenly transmitted to the opening and closing plate 44 through connecting rod 45, ensuring that each opening and closing action is precise and synchronized. No additional pneumatic pump, motor and control system are required, which reduces equipment cost and energy consumption from the source.

[0051] Specifically, the cones stacked on the unloading rack 10 are released one by one by the unloading assembly 12. The lifting assembly 13 drives the clamping assembly 4 to rise, and the lower pressure plate 17 triggers the clamping assembly 4 to close, completing the cone clamping. The conveyor chain 3 carries the cones into the fixed frame 6, and the first flipping plate 9 drives the cones to rotate to the appropriate posture. The first and second spraying parts simultaneously complete the outer and inner wall spraying. After spraying, the cones continue to move with the conveyor chain. The cones are conveyed to the bottom of the filling device 11, and the second flipping plate 14 adjusts them to a vertical posture. The filling device completes the ice cream filling. After filling, the cones are conveyed to the receiving area. The arc-shaped limiting plate 16 keeps them in a vertical posture, and the upper pressure plate 18 triggers the clamping assembly to release. The cones fall into the placement holes of the collection box 15, and the collection box moves stepwise to achieve continuous collection.
