[0003] In actual large-scale production, the height difference between the nozzle and the mold cavity opening will cause the candy liquid to splash during pouring. The existing process designs the mold as a plurality of independent single-row plate structure mold plates, each of which is provided with a row of uniformly arranged mold cavities, and a lifting mechanism is matched, when a single mold plate is accurately conveyed to the pouring station through the conveying belt, the lifting mechanism will stably lift the mold plate upward, so that the nozzle part is accurately inserted into the mold cavity, after pouring is completed, the mold plate is lowered and reset to continue conveying, so as to shorten the falling path of the candy liquid and greatly reduce the situation that the candy liquid splashes out of the mold cavity.

[0004] Because the candy liquid has high viscosity, after the pouring process is completed, a small amount of candy liquid will inevitably remain on the inner wall and port of the nozzle.

[0026] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0027] Example: A candy casting and demolding device, reference Figure 1 and Figure 3 The system includes a machine body 1, which has a pouring station 111, a cooling station 121, and a demolding station 131. The pouring station 111 is equipped with a nozzle 112. The machine body 1 also has a conveying assembly 2 and a mold 3. The nozzle 112 is fixedly installed on the top of the machine body 1 by a bracket. Multiple molds 3 are provided. Figure 2Each mold 3 has multiple evenly distributed mold cavities 311. The mold 3 is fixedly mounted on the conveying assembly 2. The conveying assembly 2 drives the mold 3 to move. During pouring, the discharge end of the nozzle 112 is opposite to the opening of the mold cavity 311. The machine body 1 includes a baffle plate 321 and a first drive assembly 331. The baffle plate 321 is rotatably mounted on the mold 3 and is located above the opening of the mold cavity 311. The baffle plate 321 includes a hollow part 322 and a baffle part 323. The first drive assembly 331 is fixedly mounted on the mold 3 and drives the baffle plate 321 to rotate, so that the hollow part 322 and the baffle part 323 alternately face the opening of the mold cavity 311. When the baffle plate 321 rotates, the discharge end of the nozzle 112 is opposite to the opening of the mold cavity 311. When the nozzle 112 rotates to face the opening of the mold cavity 311, the syrup output from the nozzle 112 enters the mold cavity 311 through the nozzle 322. After pouring, due to the viscosity of the syrup, a small amount of syrup will remain on the inner wall of the nozzle 112 and the discharge end. If it is not blocked in time, raised defects will form on the finished candy, affecting the appearance standard of the finished candy. The first drive component 331 drives the baffle plate 321 to rotate. The baffle plate 321 rotates to face the opening of the mold cavity 311 with the baffle part 323, thereby blocking the opening of the mold cavity 311 and preventing the residual syrup on the nozzle 112 from falling into the poured mold cavity 311. It can also prevent external impurities from falling into the mold cavity 311, ensuring the cleanliness of the candy molding environment.

[0028] refer to Figure 1 and Figure 3 The conveying assembly 2 includes a transmission gear 211, a conveying chain 212, and a conveying drive component. The transmission gear 211 is rotatably mounted on the machine body 1. There are four sets of transmission gears 211, located at the four corners of the machine body 1. The conveying chain 212 is driven by the transmission gear 211. There are two sets of conveying chains 212. The mold 3 is located between the two sets of conveying chains 212. The conveying chain 212 is provided with an elastic connector. The elastic connector has elastic deformation properties and is fixedly mounted on two adjacent chain links. The elastic connector is fixed to the conveying chain 212 to ensure the normal transmission of the conveying chain 212. A certain gap is left between adjacent molds 3. The conveying drive component is fixedly mounted on the machine body 1. In this embodiment, the conveying drive component includes a motor. The output end of the conveying drive component is fixedly connected to the transmission gear 211. The transmission gear 211 drives the two sets of conveying chains 212 to convey synchronously, thereby realizing the precise conveying of the mold 3.

[0029] refer to Figure 3 and Figure 5The machine body 1 is equipped with a lifting assembly 4, which includes a lifting rod 411 and a lifting drive component 421. The lifting rod 411 is positioned below the mold 3 to be poured, and its pushing center is aligned with the center of the mold 3 to ensure that the mold 3 moves smoothly upward during lifting, so that all mold cavity 311 openings are precisely aligned with the discharge end of the nozzle 112. The lifting drive component 421 is fixedly installed on the machine body 1, and its output end is connected to the lifting rod 411. The conveying chain 212 includes elastic chain segments that can elastically deform. When the mold 3 is conveyed to below the nozzle 112, it is combined with... Figure 4 The lifting drive component 421 drives the lifting rod 411 to rise, thereby lifting the mold 3 to be poured upward elastically, ensuring that the nozzle 112 and the mold cavity 311 are accurately aligned, avoiding pouring deviation. The elastic chain segments deform during the lifting process, absorbing the impact force, ensuring that the mold 3 rises and falls smoothly, reducing the impact of vibration on the syrup flow, and not affecting the continuity of the transmission of the conveyor chain 212. There is a certain gap between adjacent molds 3, which makes it easy for the lifting component 4 to lift a single mold 3 independently, avoiding mutual interference between adjacent molds 3.

[0030] refer to Figure 1 and Figure 5 After the lifting rod 411 retracts, the mold 3 continues to move with the conveyor chain 212 into the cooling station 121, and then... Figure 4 At this time, the baffle plate 321 is still in the blocking state to prevent foreign objects from contaminating it. The cooling station 121 is equipped with a cooling device 122 to force the mold 3 to cool it, so that the syrup in the mold cavity 311 can quickly solidify into hard candy. The mold 3 continues to be conveyed smoothly until it is conveyed to the demolding station 131.

[0031] refer to Figure 4 and Figure 6 The demolding station 131 is equipped with a demolding mechanism 5, which includes an ejector pin assembly 511 and a demolding drive assembly 521. The ejector pin assembly 511 is set on the mold 3 and is located at the bottom of the mold cavity 311. After the syrup in the mold cavity 311 is rapidly solidified, the mold cavity 311 moves with the mold 3 and changes from an upward opening to a downward opening. The baffle part 323 of the baffle cover plate 321 always remains opposite to the opening of the mold cavity 311 to prevent the candy from falling off the mold 3 before demolding.

[0032] refer to Figure 4 and Figure 6Two sets of demolding drive components 521 are provided, and the two sets of demolding drive components 521 are fixedly installed on both sides of the machine body 1. The demolding drive component 521 includes a demolding cylinder 522, a connecting rod structure 523, and a pressure plate 524. The output shaft of the demolding cylinder 522 is fixed to the connecting rod structure 523. The end of the connecting rod structure 523 away from the demolding cylinder 522 is fixedly connected to the pressure plate 524. The demolding cylinder 522 drives the pressure plate 524 to push the ejector pin assembly 511 downward through the connecting rod structure 523. The ejector pin assembly 511 moves down and pushes the formed candy toward the opening of the mold cavity 311 until the candy is completely pushed out of the mold cavity 311. A collection conveyor belt is provided on the machine body 1. The collection conveyor belt is located below the demolding station 131. The demolded candy falls onto the collection conveyor belt and enters subsequent packaging and other processes.

[0033] refer to Figure 3 and Figure 5 The demolding drive assembly 521 is located between the upper mold 3 to be poured and the lower mold 3 that has already been poured. There are two demolding cylinders 522 and connecting rod structures 523. The two demolding cylinders 522 and connecting rod structures 523 are symmetrically arranged at both ends of the pressure plate 524. The demolding cylinders 522 are inclined. Since the space between the mold 3 to be poured and the lower mold 3 that has already been poured is limited, the inclined setting of the demolding cylinders 522 saves space compared to vertical installation. The connecting rod structure 523 can ensure that the pressure plate 524 can smoothly push the ejector pin assembly 511 downward through lever arm conversion, thereby optimizing the space height.

[0034] refer to Figure 3 and Figure 4 The ejector pin assembly 511 includes a pressing ejector pin 512, a sleeve 513, and an elastic element 514. The pressing ejector pin 512 is slidably installed in the mold cavity 311 along the depth direction. The pressing ejector pin 512 includes a sealing part 5121 that seals the mold cavity 311. The sealing part 5121 is located inside the mold cavity 311. The sleeve 513 is sleeved on the outside of the pressing ejector pin 512. The pressing ejector pin 512 and the sleeve 513 are slidably engaged. The sleeve 513 provides sliding guidance for the pressing ejector pin 512. One end of the sleeve 513 is fixedly connected to the mold 3, thereby limiting the sliding stroke of the pressing ejector pin 512. Figure 6 One end of the lower ejector pin 512, away from the mold cavity 311, extends outward from the sleeve 513 and is used by the pressure plate 524 to push the lower ejector pin 512 downward. The elastic element 514 is set as a spring and is sleeved on the lower ejector pin 512. One end of the elastic element 514 abuts against the end of the lower ejector pin 512, and the other end abuts against the mold 3.

[0035] refer to Figure 3 and Figure 4 In the initial state, the elastic element 514 is in a naturally extended state, and the sealing part 5121 fits against the bottom of the mold cavity 311. During pouring, it prevents material from leaking from the bottom of the mold cavity 311.Figure 6 During demolding, the demolding cylinder 522 drives the pressure plate 524 to press the end of the pressing pin 512 downwards via the connecting rod structure 523. The pressing pin 512 moves towards the opening of the mold cavity 311, and the sealing part 5121 pushes the candy towards the opening of the mold cavity 311. The elastic element 514 is deformed by the compression. With the buffering effect of the elastic element 514, the candy is smoothly pushed out of the mold cavity 311. After demolding, the elastic element 514 pushes the pressing pin 512 back to its original position under its own elastic force, and the sealing part 5121 re-fits the bottom of the mold cavity 311. The elastic pressing method can ensure that the candy is pushed out while avoiding excessive impact on the candy, thus protecting the shape and quality of the candy.

[0036] refer to Figure 3 and Figure 4 The inner wall of the hollow part 322 is coated with an anti-stick coating. The inner wall of the hollow part 322 gradually narrows inward along the direction of material falling, which facilitates the guidance of liquid syrup into the mold cavity 311. The material blocking part 323 is rotatably connected to the material blocking cover plate 321 via a hinge 324. A torsion spring 326 is fitted on the pivot 325 of the hinge 324. One end of the torsion spring 326 abuts against the material blocking part 323, and the other end abuts against the material blocking cover plate 321. Under natural conditions, the torsion spring 326 is in a state of slight deformation, ensuring that the material blocking part 323 keeps the opening of the mold cavity 311 sealed, thus ensuring the cleanliness of the mold cavity 311.

[0037] refer to Figure 3 and Figure 4 When the mold 3 moves, causing the opening of the mold cavity 311 to change from facing upwards to facing downwards, the stop part 323 remains tightly fitted to the opening of the mold cavity 311 under the preload of the torsion spring 326, and then combined with... Figure 6 The candy is ejected outwards as the demolding cylinder 522 drives the pressure plate 524 to push the ejector pin assembly 511 downwards. At this time, the candy applies pressure to the stop part 323, overcoming the elastic force of the torsion spring 326, causing the stop part 323 to rotate around the pivot 325 of the hinge 324. The mold cavity 311 is located at the edge of the stop part 323, making it easier to push the stop part 323 to rotate around the pivot 325 of the hinge 324. The candy smoothly leaves the mold cavity 311 and falls into the collection conveyor belt below, completing the automatic demolding. The whole process is smooth and stable, effectively preventing syrup leakage and jamming. After the candy is demolded, the stop part 323 quickly returns to its original position under the restoring force of the torsion spring 326, preventing impurities from entering the mold cavity 311.

[0038] refer to Figure 2 and Figure 4The first drive assembly 331 includes a transmission rod 332 and a first drive component 333. The transmission rod 332 is configured as a worm gear and is rotatably mounted on the mold 3 via bearings. The periphery of the baffle plate 321 is provided with gears that drive and cooperate with the transmission rod 332. The baffle plate 321 is equivalent to the function of a worm gear. The first drive component 333 is fixedly mounted on the mold 3 and includes a motor. After the first drive component 333 is working, the transmission rod 332 meshes with the periphery of the baffle plate 321. The rotation of the transmission rod 332 drives the baffle plate 321 to rotate, thereby realizing the switching between the baffle part 323 and the hollow part 322, and thus realizing the opening and closing of the mold cavity 311.

[0039] refer to Figure 2 and Figure 4 During the pouring process, the first drive unit 333 is activated, the transmission rod 332 rotates and drives the baffle plate 321 to rotate through meshing, so that the baffle part 323 disengages from the opening of the mold cavity 311, and the hollow part 322 is opposite to the opening of the mold cavity 311, providing a channel for syrup injection. After the syrup is poured, the first drive unit 333 drives the transmission rod 332 to rotate in the opposite direction, and the baffle part 323 reseals the opening of the mold cavity 311, realizing the switching between the two states of automated syrup pouring and sealing.

[0040] The implementation principle of this application embodiment is as follows: the conveying drive unit drives two sets of conveying chains 212 to operate through the transmission gear 211. The mold 3 moves with the conveying chain 212. When the mold 3 reaches the pouring station 111, the lifting rod 411 pushes the mold 3 upward under the drive of the lifting drive unit 421. The elastic chain segments of the conveying chain 212 deform, ensuring that the mold 3 can move upward smoothly. All the openings of the mold cavity 311 on the mold 3 to be poured are precisely aligned with the nozzle 112. The first drive unit 333 drives the transmission rod 332 to rotate, and drives the baffle plate 321 to rotate through gear meshing. The perforated part 322 is switched to the position above the opening of the mold cavity 311. The syrup output from the nozzle 112 is injected into the mold cavity 311 through the perforated part 322. After the pouring is completed, the first driving component 333 drives the baffle plate 321 to rotate so that the baffle part 323 blocks the opening of the mold cavity 311, preventing the residual syrup from the nozzle 112 from dripping into the mold cavity 311. Then the mold 3 enters the cooling station 121 with the conveyor chain 212. The cooling equipment 122 forces the mold cavity 311 to cool it, so that the syrup quickly solidifies into hard candy. The baffle part 323 always remains in a blocking state to ensure the cleanliness of the mold cavity 311.

[0041] Mold 3 continues to flow to demolding station 131. As it moves with conveyor chain 212, mold cavity 311 changes from an upward opening to a downward opening. The stop part 323, under the action of torsion spring 326, tightly fits the opening of mold cavity 311 to prevent the candy from falling off prematurely. Demolding cylinder 522 drives pressure plate 524 to press down through connecting rod structure 523. The downward pressing pin 512 slides in sleeve 513. The sealing part 5121 of the downward pressing pin 512 pushes the candy towards the opening of mold cavity 311. As pressure plate 524 continues to press down, stop part 323 rotates around rotating shaft 325, and mold cavity 311 opening is opened. The candy smoothly leaves mold cavity 311 and falls into the collection conveyor belt below. After demolding, elastic element 514 pushes downward pressing pin 512 to reset, and torsion spring 326 drives stop part 323 to return to its original position.

[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.
