Description

Technical Field

[0001] This application relates to the field of candy casting technology, and in particular to a filling candy casting device. Background Technology

[0002] In the food processing industry, confectionery production has always been a crucial component. As consumers' demands for confectionery flavor and quality continue to rise, filled candies, with their unique texture and rich layers, are gaining increasing popularity. The growing market demand for filled candies has driven confectionery manufacturers to continuously explore more efficient and higher-quality production technologies. Efficient filled candy production technologies not only improve production efficiency and meet substantial market demand but also enhance product quality and stability, thereby strengthening the company's market competitiveness.

[0003] In the past, there were generally two methods used in the industry to produce filled candies. One method involved separately making the outer layer and filling of the candy, then manually or using simple mechanical devices to wrap the filling inside the outer layer. This method required significant manual labor, was cumbersome, and had low production efficiency. The other method used traditional casting equipment, but this equipment was often simple in structure and limited in function, only capable of basic material conveying and pouring, and unable to precisely control the amount and speed of material injected into the outer layer and filling. Traditional casting equipment also struggled to ensure the uniformity and stability of the material during conveying, easily leading to inconsistent quality of the filled candies. Summary of the Invention

[0004] In order to solve the problems of existing technologies that cannot automatically pour the inner and outer layers and cannot accurately control the injection volume and injection speed of the outer layer and filling materials, this application provides a filling candy pouring device.

[0005] The filling candy casting device provided in this application adopts the following technical solution: A filling candy casting device includes a frame, a lifting mechanism, a first hopper, a second hopper, a first piston, a second piston, a filling module, and a casting module. The first and second hoppers are respectively mounted on the frame. The lifting mechanism is mounted on the frame and located above the first and second hoppers. The first and second pistons are both mounted on the drive end of the lifting mechanism. The filling module is mounted on the frame and has a first feeding channel, a first extrusion channel, a second feeding channel, and a second extrusion channel. The first feeding channel connects the first hopper and the first extrusion channel. The first piston is inserted into the first extrusion channel, and the second feeding channel is used to connect the second hopper and the second extrusion channel. The second piston is inserted into the second extrusion channel. The casting module includes a casting body and a casting head disposed on the casting body. The casting body is connected to the injection module. The casting head includes a casting core sleeve and a casting outer sleeve. The casting core sleeve is located inside the casting outer sleeve. The casting body is provided with an outer sleeve feeding channel and a core sleeve feeding channel. The outer sleeve feeding channel connects the first extrusion channel and the casting outer sleeve, and the core sleeve feeding channel connects the second extrusion channel and the casting core sleeve.

[0006] By adopting the above technical solution, the first hopper is used to store the outer coating material of the sandwich candy, and the second hopper is used to store the filling material of the sandwich candy. The outer coating material is fed into the first extrusion channel through the first feeding channel, and the filling material is fed into the second extrusion channel through the second feeding channel. The first piston is driven to descend and squeeze the outer and inner coating materials from the first extrusion channel into the outer casing feeding channel on the casting module, and then into the casting outer casing through the outer casing feeding channel. Similarly, the second piston is driven to squeeze the filling material in the second extrusion channel into the core sleeve feeding channel, and then into the casting core sleeve through the core sleeve feeding channel. Finally, the casting outer casing and the casting core sleeve are cast together to form the sandwich candy. This structure realizes automatic casting of two materials without human operation, which greatly improves efficiency. At the same time, the casting speed and injection volume of the materials can be controlled by the size and number of the first feeding channel, the second feeding channel, the first extrusion channel, and the second extrusion channel, which improves the casting quality of the sandwich candy.

[0007] Optionally, the casting head is located below the region between the first piston and the second piston. The casting body includes an upper casting section and a lower casting section. The upper casting section is provided with a first vertical guide hole and a second horizontal guide groove. The lower casting section is provided with a first horizontal guide groove. The upper end of the first vertical guide hole is connected to a first extrusion channel, and the lower end is connected to one end of the first horizontal guide groove. The other end of the first horizontal guide groove is connected to the casting outer sleeve. The first vertical guide hole and the first horizontal guide groove constitute the outer sleeve feeding channel. One end of the second horizontal guide groove is connected to a second extrusion channel, and the other end is connected to the casting core sleeve. The second horizontal guide groove constitutes the core sleeve feeding channel.

[0008] By adopting the above technical solution, due to the arrangement of two hoppers and two pistons, and the fact that two materials are poured from a single pouring head, the pouring head on the casting module cannot be aligned with the first and second extrusion channels on the injection module. Therefore, a first transverse guide channel connects the staggered pouring outer sleeve and the first extrusion channel, and a second transverse guide channel connects the staggered second extrusion channel and the pouring core sleeve, thus enabling the two materials to be introduced into the inner and outer pouring sleeves of the same pouring head. Furthermore, the upper and lower pouring sections facilitate the processing of the first and second transverse guide channels.

[0009] Optionally, the casting body is provided with a heat-insulating medium pipeline.

[0010] By adopting the above technical solution, the outer coating material and the core material to be poured are kept warm by the insulating medium, preventing the materials from condensing and affecting the pouring process. Optionally, the casting module is detachably connected to the injection module.

[0011] By adopting the above technical solution, multiple casting modules can be set up. When one casting module fails, it can be replaced with another casting module, or different casting modules can be used for casting in different scenarios.

[0012] Optionally, the injection module is provided with a first valve stem, which divides the first extrusion channel into upper and lower sections. The first valve stem is provided with a vertical through hole and a lateral bending hole. The vertical through hole and the lateral bending hole are arranged in a staggered manner along the axial direction of the first valve stem. The lateral bending hole is used to connect the first feeding channel and the upper section of the first extrusion channel so that the material in the first hopper enters the upper section of the first extrusion channel. The vertical through hole is used to connect the upper section of the first extrusion channel and the lower section of the first extrusion channel so that the first piston squeezes the material in the upper section of the first extrusion channel into the lower section of the first extrusion channel. A lateral drive is provided on one side of the frame. The lateral drive is used to drive the first valve stem to move laterally so that the vertical through hole and the lateral bending hole are connected to the first extrusion channel in sequence.

[0013] By adopting the above technical solution, the setting of the first valve stem and the lateral drive realizes the switching between the two states of feeding and extruding in the first extrusion channel, ensuring the smooth progress of casting.

[0014] Optionally, the injection module is provided with a second valve stem, which divides the second extrusion channel into upper and lower sections. The second valve stem is provided with a vertical through hole and a lateral bending hole. The vertical through hole and the lateral bending hole are arranged in a staggered manner along the axial direction of the second valve stem. The lateral bending hole is used to connect the second feeding channel and the upper section of the second extrusion channel so that the material in the second hopper enters the upper section of the second extrusion channel. The vertical through hole is used to connect the upper section of the second extrusion channel and the lower section of the second extrusion channel so that the second piston squeezes the material in the upper section of the second extrusion channel into the lower section of the second extrusion channel. A lateral drive is provided on one side of the frame. The lateral drive is used to drive the second valve stem to move laterally so that the vertical through hole and the lateral bending hole are connected to the second extrusion channel in sequence.

[0015] By adopting the above technical solution, the setting of the second valve stem and the lateral drive realizes the switching between the two states of feeding in the second extrusion channel and extrusion in the second extrusion channel, ensuring the smooth progress of casting.

[0016] Optionally, at least two casting bodies are provided, at least two injection modules are provided, at least two sets of first pistons are provided, at least two sets of second pistons are provided, one casting body corresponds to one injection module, and one injection module corresponds to one set of first pistons and one set of second pistons.

[0017] By adopting the above technical solution, the casting module and the slurry injection module are separated into two, forming several independent units. This facilitates modular management and maintenance. If one casting body or slurry injection module fails, the remaining casting bodies or slurry injection modules can continue to operate, avoiding interruption of the casting process.

[0018] Optionally, the frame includes an upper support base and a lower support base. The first and second material bins are installed on the lower support base. The lifting mechanism is provided in two sets, and the two sets of lifting mechanisms drive the first piston and the second piston respectively. The lifting mechanism includes a motor, a lifting plate, and two telescopic cylinders. The motor and each telescopic cylinder body are installed on the upper support base. The telescopic cylinder is provided with a lead screw and a lead screw sleeve. A transmission mechanism is provided between the motor and the lead screw sleeve to transmit the rotation of the motor to the lead screw sleeve to extend and retract the lead screw. The telescopic end of the lead screw is connected to the lifting plate.

[0019] By adopting the above technical solution, one motor drives the extension and retraction of two telescopic cylinders, thereby greatly improving the stability of the lifting and lowering movement of the lifting plate, ensuring the synchronization of the lifting and lowering actions of the two telescopic cylinders, and ensuring the stability of candy pouring.

[0020] Optionally, a sealing gasket layer is provided between the injection module and the casting module.

[0021] By adopting the above technical solution, the sealing gasket layer seals the gap between the injection module and the casting module, preventing the problem of material leakage during casting.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. This sandwich candy casting equipment enables automatic casting of two types of materials without the need for manual operation, greatly improving efficiency. At the same time, the casting speed and injection volume can be controlled by the size and quantity of the first feeding channel, the second feeding channel, the first extrusion channel, and the second extrusion channel, thereby improving the casting quality of the sandwich candy.

[0023] 2. The first and second transverse guide channels connect the staggered extrusion channels with the inner and outer casting sleeves, enabling the two materials to be introduced into the inner and outer casting sleeves of the same casting head.

[0024] 3. The extrusion channel and feeding channel on the injection module can provide stable injection pressure and injection speed, avoiding the problem of dripping. The valve stem and lateral drive settings realize the switching between the feeding and extrusion states of the extrusion channel, ensuring the smooth progress of casting.

Detailed Implementation

[0040] The following is in conjunction with the appendix Figure 1-14 This application will be described in further detail.

[0041] The directional terms such as "up," "down," "left," "right," "front," and "back" used in this application only represent relative positions in the diagram and are used for the convenience of describing this application. They do not represent the absolute position of the product and should not be regarded as limitations on this application.

[0042] Example 1 This application discloses a filling candy casting device.

[0043] like Figure 1 and Figure 2 As shown, the candy filling equipment of this embodiment mainly includes a frame 100, a lifting mechanism 200, a first hopper 1, a second hopper 2, a first piston 300, a second piston 400, an injection module 500, and a pouring module 600.

[0044] The frame 100 includes an upper support base 110 and a lower support base 120, which are connected by a height adjustment mechanism 130.

[0045] The lifting mechanism 200 is mounted on the upper support 110. Two sets of lifting mechanisms 200 are provided, each driving the lifting of the first piston 300 and the second piston 400 respectively. Figure 11 As shown, the lifting mechanism 200 includes a motor 210, a lifting plate 220, and a telescopic cylinder 230. The motor 210 and the cylinder body of the telescopic cylinder 230 are mounted on the upper support base 110. The telescopic cylinder 230 is provided with a lead screw 231 and a lead screw sleeve 232. A transmission mechanism 240 is provided between the motor 210 and the lead screw sleeve 232. The transmission mechanism 240 transmits the rotation of the motor 210 to the lead screw sleeve 232. The rotation of the lead screw sleeve 232 drives the lead screw 231 to extend and retract. The extension end of the lead screw 231 is connected to the lifting plate 220, thereby realizing the lifting of the lifting plate 220.

[0046] The first hopper 1 and the second hopper 2 are arranged side by side on the lower support 120, both horizontally positioned. The first hopper 1 stores the outer coating material of the sandwich candy, and the second hopper 2 stores the filling material of the sandwich candy. For a reasonable and compact installation, the first piston 300 is located inside the first hopper 1, and the second piston 400 is located inside the second hopper 2. Two sets of lifting mechanisms 200 are respectively located above the first hopper 1 and the second hopper 2. The first hopper 1 has a double-shell structure with an outer shell and an inner shell, which serves as insulation, thereby slowing down the solidification rate of the material inside the hopper. Similarly, the second hopper 2 also has a double-shell structure.

[0047] like Figure 3As shown, the first piston 300 and the second piston 400 have the same structure, installation method, and driving method. For ease of description, the first piston 300 is used as an example below. The first piston 300 has a boss head at the top, and the bottom of the lifting plate 220 has a connecting plate 221 with a T-slot. The boss head at the top of the first piston 300 is engaged in the T-slot. The lower end of the first piston 300 has a sealing sleeve 310, the lower end of which passes through the lower support seat 120. The upper end extends out of the lower support seat 120. The lower end of the first piston 300 is inserted into the sealing sleeve 310. Since there is flowing material in the first hopper 1, the sealing sleeve 310 can also prevent the flowing material from contacting the outer wall of the first piston 300, thus not affecting the extension and retraction of the piston.

[0048] The injection module 500 and the lower support base 120 are fixedly connected by bolts. Similarly, taking the injection structure of the first piston 300 as an example. Figure 4 As shown, the feeding module 500 is provided with a first feeding channel 510, and the lower support base 120 is provided with a feeding hole 121 and a suction chamber 122. The feeding hole 121 is vertically arranged, with its upper end connected to the first hopper 1 and its lower end connected to the first feeding channel 510. The upper end of the suction chamber 122 is connected to the sealing sleeve 310 and its lower end is connected to the first extrusion channel 520. In order to improve the speed and pressure of the material entering the suction chamber 122, two feeding holes 121 are provided, and two corresponding first feeding channels 510 are also provided. The two first feeding channels 510 are respectively located on the left and right sides of the first extrusion channel 520. Material from the first hopper 1 enters the first feeding channel 510 through the feed holes 121 on both sides, and then enters the first extrusion channel 520 and the extraction chamber 122 from the first feeding channel 510. Finally, the lifting plate 220 descends, and the first piston 300 descends, pushing the material in the extraction chamber 122 and the first extrusion channel 520 downwards, so that the material is squeezed into the casting module 600 below for casting. It should be noted that the extraction and extrusion method of the second piston 400 is the same as that of the first piston 300. Similarly, two second feeding channels 530 are also provided on both sides of the second extrusion channel 540. The two second feeding channels 530 are connected to the second hopper 2 through two feed holes 121. The extraction chamber 122 is provided between the second extrusion channel 540 and the sealing sleeve 310 of the second piston 400.

[0049] like Figure 5 and Figure 7As shown, the casting module 600 includes a casting body 610 and a casting head 620 disposed on the casting body 610. The casting body 610 is connected to the injection module 500, and a sealing gasket 3 is provided between the two. The casting head 620 includes a casting core sleeve 621 and a casting outer sleeve 622. The casting core sleeve 621 is located inside the casting outer sleeve 622, and the two are arranged coaxially. The casting body 610 is provided with an outer sleeve feeding channel 601 and a core sleeve feeding channel 602. A first extrusion channel 520 is connected to the casting outer sleeve 622 through the outer sleeve feeding channel 601, and a second extrusion channel 540 is connected to the casting core sleeve 621 through the core sleeve feeding channel 602. The outer coating material in the first hopper 1 is squeezed by the first piston 300 into the first extrusion channel 520, and then enters the outer casing feeding channel 601, and then enters the casting outer casing 622 for candy coating pouring. At the same time, the filling material in the second hopper 2 is squeezed by the second piston 400 into the second extrusion channel 540, and then enters the core sleeve feeding channel 602, and then enters the casting core sleeve 621 for filling. The candy coating and filling are poured synchronously. The injection volume and injection speed of different materials can be controlled by the extraction chamber 122 and the first and second extrusion channels.

[0050] In this embodiment, the casting head 620 is located below the region between the first piston 300 and the second piston 400, and the first extrusion channel 520 and the second extrusion channel 540 cannot be vertically directly connected to the casting outer sleeve 622 and the casting core sleeve 621. Therefore, the casting body 610 includes an upper casting block 611 and a lower casting block 612, which are fixedly connected. The upper casting block 611 is provided with a first vertical guide hole 603 and a second horizontal guide groove 604, and the lower casting block 612 is provided with a first horizontal guide groove 605. The upper end of the first vertical guide hole 603 is connected to the first extrusion channel 520, and the lower end is connected to one end of the first horizontal guide groove 605. The other end of the first horizontal guide groove 605 is connected to the casting jacket 622. The first vertical guide hole 603 and the first horizontal guide groove 605 constitute the jacket feeding channel 601. One end of the second horizontal guide groove 604 is connected to the second extrusion channel 540, and the other end is connected to the casting core sleeve 621. The second horizontal guide groove 604 constitutes the core sleeve feeding channel 602. The first horizontal guide groove 605 connects the staggered casting jacket 622 and the first extrusion channel 520, and the second horizontal guide groove 604 connects the staggered second extrusion channel 540 and the casting core sleeve 621, thus realizing the placement of the casting head 620 in the central area of ​​the casting module 600.

[0051] In this embodiment, to improve the casting efficiency of the sandwich candy, the casting heads 620 are arranged in two rows, with multiple casting heads 620 in each row spaced apart. The arrangement direction is consistent with the arrangement direction of the first hopper 1 (or the second hopper 2), both being horizontally arranged. The two first horizontal guide channels 605 corresponding to two adjacent casting sleeves 622 in the same row are staggered by a certain position, and the two second horizontal guide channels 604 corresponding to two adjacent casting core sleeves 621 in the same row are also staggered by a certain position. One row of casting heads 620 corresponds to two rows of first pistons 300, and the other row of casting heads 620 corresponds to two rows of second pistons 400, thereby increasing the flow rate and pressure of the two materials entering the inner and outer sleeves of the casting heads.

[0052] In this embodiment, the first extrusion channel 520 has two states: material extraction and material extrusion, thus requiring switching between the two states. Therefore, as follows... Figures 8 to 10 As shown, a first valve stem 710 is installed inside the injection module 500. The first valve stem 710 divides each first extrusion channel 520 into upper and lower sections. The first valve stem 710 has a vertical through hole 701 and a lateral bending hole 702 (L-shaped hole) corresponding to each first extrusion channel 520. The vertical through hole 701 and the lateral bending hole 702 are staggered along the axial direction of the first valve stem 710. The lateral bending hole 702 connects the first feeding channel 510 and the upper section of the first extrusion channel 520, so that the material in the first hopper 1... The material enters the upper section's first extrusion channel 520. A vertical through-hole 701 connects the upper section's first extrusion channel 520 and the lower section's first extrusion channel 520, allowing the first piston 300 to extrude the material from the upper section's first extrusion channel 520 into the lower section's first extrusion channel 520. A transverse drive 730 is provided on one side of the frame 100, driving the first valve stem 710 to move laterally so that the vertical through-hole 701 and the lateral bending hole 702 sequentially connect with the first extrusion channel 520. It should be noted that since the first piston 300 has two horizontal rows, the two first pistons 300 on the same longitudinal direction in the two horizontal rows correspond to three feed holes 121. These three feed holes 121 correspond to one of the three first feeding channels 510. Therefore, two lateral bending holes 702 are required, and the two lateral bending holes 702 are combined into a three-way structure. This three-way structure connects the first extrusion channel 520 and the two first feeding channels 510. In addition to this embodiment, the two first pistons 300 on the same longitudinal direction in the two horizontal rows can also have four feed holes 121, that is, each first piston 300 has two separate feed holes 121.

[0053] The lateral drive 730 is preferably a lateral cylinder. When material needs to be extracted, the lateral cylinder drives the first valve rod 710 to move laterally, so that the lateral bending hole 702 moves to the position of the upper first extrusion channel 520. At this time, the feed hole 121, the first feeding channel 510, the lateral bending hole 702, and the upper first extrusion channel 520 are connected. By moving the first piston 300 upward to extract air, the material in the first hopper 1 is sucked into the upper first extrusion channel 520, and part of the material enters the extraction chamber 122, waiting for extrusion and casting. After the material extraction is completed, the horizontal cylinder drives the first valve rod 710 to retract. At this time, the lateral bending hole 702 leaves the first extrusion channel 520, and the vertical through hole 701 moves to the position of the first extrusion channel 520. At this time, the first feeding channel 510 is disconnected from the upper section of the first extrusion channel 520. The upper section of the first extrusion channel 520, the vertical through hole 701, and the lower section of the first extrusion channel 520 are connected in sequence. By moving the first piston 300 downward, the material in the extraction chamber 122 and the first extrusion channel 520 is squeezed out and enters the lower outer jacket feeding channel 601.

[0054] Similarly, the injection module 500 is provided with a second valve stem 720, which is also provided with a vertical through hole 701 and a lateral bending hole 702. The second valve stem 720 is provided with a corresponding horizontal drive 730, so that the second extrusion channel 540 can have two states: material extraction and material extrusion. Its structure and principle are the same as those of the first valve stem 710, and will not be described in detail here.

[0055] In this embodiment, as Figure 6 As shown, the casting body 610 is provided with a heat-insulating medium pipe 607. The heat-insulating medium is used to keep the outer garment material and the core material to be cast warm, so as to prevent the material from condensing and affecting the casting.

[0056] In this embodiment, for modular management and maintenance, two casting bodies 610 and two injection modules 500 are provided. The aforementioned multiple first pistons 300 are arranged into two groups, and the aforementioned multiple second pistons 400 are arranged into two groups. One casting body 610 corresponds to one injection module 500, and one injection module 500 corresponds to one group of first pistons 300 and one group of second pistons 400, thereby forming two groups of casting units. When one group of casting units fails, casting can continue through the other group, thus not affecting the casting process.

[0057] In this embodiment, due to the large number of first pistons 300 and second pistons 400, the lifting plate 220 is relatively long. To improve its lifting stability, one lifting plate 220 corresponds to one motor 210 and two telescopic cylinders 230. The two telescopic cylinders 230 are connected to the motor 210 through a transmission mechanism 240, such as... Figure 11 and Figure 12As shown, the transmission mechanism 240 includes a driving pulley 241, a driven pulley 242, a driven pulley 243, a tensioning pulley 244, a tensioning pulley 245, and a synchronous belt 246. The driving pulley 241 is located at the output end of the motor 210. The driven pulley 242 is coaxially fixed to the lead screw sleeve 232 of one telescopic cylinder 230, and the driven pulley 243 is coaxially fixed to the lead screw sleeve 232 of another telescopic cylinder 230. The tensioning pulley 244 is located between the driving pulley 241 and the driven pulley 242, and the tensioning pulley 245 is located between the driving pulley 241 and the driven pulley 243. The synchronous belt 246 is wound around the driving pulley, each driven pulley, and each tensioning pulley. When the motor 210 rotates, the driving wheel 241 rotates, and the synchronous belt 246 rotates, driving the driven wheel 242 and the driven wheel 243 to rotate, which in turn drives the lead screw sleeve 232 of the two telescopic cylinders 230 to rotate, ultimately realizing the telescopic movement of the two lead screws 231.

[0058] In this embodiment, the height adjustment mechanism 130 includes a height adjustment cylinder 131 and an adjustment plate 132. The adjustment plate 132 is connected to the lower support base 120, and the height adjustment cylinder 131 is mounted on the adjustment plate 132. The drive end of the height adjustment cylinder 131 is connected to the upper support base 110. The height adjustment cylinder 131 can drive the height of the upper support base 110, thereby adapting to hoppers and pistons of different heights. Multiple guide posts 140 are provided between the upper support base 110 and the lower support base 120. Two sets of height adjustment mechanisms 130 are provided, located at both ends of the frame 100.

[0059] The principle of the filling candy casting equipment in this embodiment is as follows: Assemble all the above components, adjust the height of the upper support 110 using the height adjustment mechanism 130, and then adjust the positions of the first piston 300 and the second piston 400 within the sealing sleeve 310 using the lifting mechanism 200 to reserve the size of the material extraction chamber 122. At this time, the first hopper 1 and the second hopper 2 are each filled with outer material and filling material, respectively. Next, drive the first valve stem 710 laterally using the lateral drive 730 to move the lateral bending hole 702 to the position of the first extrusion channel 520. At this time, the feed hole 121, the first feeding channel 510, the lateral bending hole 702, and the upper section of the first extrusion channel 520 are connected. By moving the first piston 300 upward to draw air, the material in the first hopper 1 is sucked into the first extrusion channel 520, waiting for extrusion and casting. After the material extraction is completed, the horizontal drive 730 drives the first valve stem 710 to retract. At this time, the lateral bending hole 702 leaves the first extrusion channel 520, and the vertical through hole 701 moves to the position of the first extrusion channel 520. At this time, the first feeding channel 510 is disconnected from the first extrusion channel 520. The first extrusion channel 520, the vertical through hole 701, and the first extrusion channel 520 are connected in sequence. The first piston 300 moves down and squeezes the outer material in the first extrusion channel 520 into the first vertical guide hole 603 on the casting body 610, and guides it into the casting outer sleeve 622 by the first horizontal guide groove 605. At the same time, the second piston 400 squeezes the filling material in the second extrusion channel 540 into the second horizontal guide groove 604 on the casting body 610, and guides it into the casting core sleeve 621 by the second horizontal guide groove 604. Finally, the casting outer sleeve 622 and the casting core sleeve 621 are cast together to form a filled candy.

[0060] Example 2 Since candies include filled and unfilled candies, in order to improve the adaptability of the equipment and to simplify the structure, the casting module 600 can be configured as a dual-material casting for filled candies and a single-material casting for unfilled candies.

[0061] like Figure 13 and 14 As shown, in this embodiment, the casting module 600 in the above embodiment is detachably connected to the injection module 500. In this embodiment, the casting module 600 used for casting double-material sandwich candies in the previous embodiment is replaced with a single-material casting module 800. The single-material casting module 800 is configured with multiple rows of casting heads to improve casting efficiency. The rest of the structure remains unchanged. In this way, the versatility of the sandwich candy casting equipment is greatly improved. It can be used again by simply replacing the two casting modules, without the need to set up separate equipment for casting double-material sandwich candies and separate equipment for casting single-material candies.

[0062] 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.
