[0002] With the continuous development of the candy market, soft candies with fillings are widely loved by consumers due to their rich taste and diverse flavor combinations. The production of soft candies with fillings with fillings usually involves a double pouring process of the soft candy shell and the fillings. However, the existing production technology of soft candies with fillings ...

[0003] Traditional production methods for soft candies mostly use a step-by-step pouring process, that is, pouring the soft candy shell first, and then injecting the filling. This process has the following problems: First, the soft candy shell is easy to solidify during the process of moving to the filling pouring station, resulting in the filling being unable to be injected evenly, affecting product quality and pass rate. Second, the step-by-step pouring process has a low degree of automation, and it is difficult to improve production efficiency.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. Efficient and automated production: The unique quantitative feeding component of the present invention cooperates with the sandwich pouring nozzle to realize the synchronous injection and integrated molding of the core material and the skin material, avoiding the process complexity and time cost caused by the step-by-step processing of the core material and the skin material in the traditional production method, and significantly improving the production efficiency. The core material and the skin material are integrally injected into the mold for molding, ensuring that the overall structure of the soft candy is tighter and the sandwich is not easy to shift or leak, which not only improves the appearance quality of the product, but also enhances the taste and stability of the product, making it more competitive in the market.

[0018] 2. Precision pouring and quality control: The equipment adopts advanced servo pouring technology. By controlling the moving distance of the valve stem, it can accurately control the pouring amount of the core material and the skin material, ensuring that the sandwich ratio is consistent each time the pouring is stable. At the same time, the design of the conveyor belt and the lifting seat collaboratively controlling the mold to track the movement of the sandwich pouring nozzle avoids the problems of sugar overflow and uneven distribution of the sandwich that may occur in the traditional pouring process, thereby improving the overall quality of the product.

[0019] 3. Simplify the production process: The production of traditional soft candies requires complex cooling and molding processes. This equipment integrates the pouring and cooling of the skin and core materials into one conveyor belt through an integrated design, which simplifies the production process, reduces the equipment footprint and operation complexity. At the same time, through the unique cooling component design, the pouring process and the cooling process can be run synchronously without affecting each other, which greatly improves production efficiency.

[0020] 4. The regulating component of the present invention can flexibly adjust the ratio of the soft candy skin material and the core material according to different taste requirements, and can produce soft candies with different filling amounts or sizes in the same batch of pouring. There is no need to add additional power for separate control. The ratio can be switched with simple operations to meet the diverse needs of the market.

[0021] 5. The design of each heating tube in the present invention can effectively maintain the temperature stability of the core material and the leather material from storage to pouring, avoid solidification or deterioration of fluidity due to temperature fluctuations, ensure the smoothness of the pouring process, and reduce the frequent cleaning and maintenance required due to solidification of the core material or thickening of the leather material, which not only reduces the production cost, but also increases the service life of the equipment.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figures 1 to 10As shown, a soft candy sandwich quantitative integrated conveying and pouring equipment includes a conveyor belt 1, a machine platform 2, a pouring device and at least two hoppers 3, the conveyor belt 1 is assembled on the machine platform 2 and a plurality of molds 4 are evenly spaced on the conveyor belt 1, each hopper 3 and the pouring device are mounted on the machine platform 2 and located above the conveyor belt 1, each hopper 3 is used to store different materials, the pouring device includes a plurality of sandwich pouring nozzles 5 and a plurality of quantitative feeding components corresponding to each hopper 3, and each feeding end in the sandwich pouring nozzle 5 is connected to each quantitative feeding component; The quantitative feeding assembly includes a rotary valve 6, a plurality of quantitative cylinders 7, a plurality of valve stems 8 and a power assembly. The rotary valve 6 is assembled at the discharge port of the hopper 3 to control the discharge of the hopper 3. The sandwich pouring nozzle 5 and the quantitative cylinder 7 are respectively connected to the rotary valve 6. The valve stem 8 is slidably arranged in the corresponding quantitative cylinder 7 and performs reciprocating motion under the drive of the power assembly. When the rotary valve 6 is switched to the state where the hopper 3 and the quantitative cylinder 7 are connected, the valve stem 8 moves to draw the material in the hopper 3 into the quantitative cylinder 7. When the rotary valve 6 is switched to the state where the quantitative cylinder 7 and the sandwich pouring nozzle 5 are connected, the valve stem 8 moves to push the material in the quantitative cylinder 7 to the sandwich pouring nozzle 5 for discharge.

[0026] In this embodiment, the rotary valve 6 includes a motor, a valve body 9 and a valve core 10. The valve body 9 is provided with a plurality of feed ports 11, a plurality of injection ports 12 and a plurality of discharge ports 13 corresponding to the number of the sandwich pouring nozzles 5 along its length direction. The valve core 10 is provided with a corresponding plurality of independent channels 14. The feed port 11 is connected to the hopper 3. The metering cylinder 7 is installed at the side end of the valve body 9 and is connected to the injection port 12. The discharge port 13 is connected to the corresponding sandwich pouring nozzle 5. The motor is connected to the valve core 10 to drive the valve core 10 to rotate and switch. The rotary valve 6 is provided with two states: in the first state, the two ends of the channel 14 are respectively connected to the corresponding feed port 11 and injection port 12; in the second state, the two ends of the channel 14 are respectively connected to the corresponding injection port 12 and discharge port 13.

[0027] In this embodiment, there are two groups of hoppers 3 and quantitative feeding components. The two groups of hoppers 3 are used to store leather materials and core materials respectively. The sandwich pouring nozzle 5 includes an inner pouring nozzle 15 and an outer pouring nozzle 16. The inner pouring nozzle 15 is arranged inside the outer pouring nozzle 16, and the discharge port height of the inner pouring nozzle 15 is higher than the discharge port of the outer pouring nozzle 16. This design can ensure that the leather material is injected before the core material, thereby ensuring that the leather material can wrap the core material. The various discharge ports 13 of the valve body 9 for conveying the leather material are respectively connected to the corresponding feed end of the outer pouring nozzle 16, and the various discharge ports 13 of the valve body 9 for conveying the core material are respectively connected to the corresponding feed end of the inner pouring nozzle 15.

[0028] In this embodiment, the number of metering cylinders 7 corresponds to the number of sandwich pouring nozzles 5, a support 17 is provided at the side end of the valve body 9, and each metering cylinder 7 is embedded in the support 17 at equal intervals, a sealing member 53 is provided at one end of the valve stem 8 close to the rotary valve 6, and the end of the valve stem 8 in each metering cylinder 7 away from the rotary valve 6 extends out of the metering cylinder 7, and the end of each valve stem 8 is connected to a connecting frame 18, and a rack 19 is provided at the side end of the connecting frame 18, and the power assembly includes a servo motor 20 and a gear 21 installed on the output shaft of the servo motor 20, and the gear 21 is meshed and connected with the rack 19, so that the servo motor 20 can drive all valve stems 8 to move synchronously; The pouring process of the device is as follows (a single sandwich pouring nozzle 5 is used as an example for explanation): the staff first pours the core material as the sandwich and the leather material as the shell into the two hoppers 3 respectively, and the conveyor belt 1 conveys the mold 4 to the sandwich pouring nozzle 5. At this time, the rotary valve 6 is switched to the first state, and the servo motors 20 on both sides operate synchronously. The servo motor 20 drives the valve stem 8 to move outward through the meshing action of the gear 21 and the rack 19. Therefore, under the action of atmospheric pressure, the core material / leather material in the hopper 3 flows through the feed port 11, the channel 14 and the injection port 12 in turn and is then drawn into the metering cylinder 7. The moving distance of the valve stem 8 can control the material drawn in. The material in the metering cylinder 7 is pushed into the corresponding inner pouring nozzle 15 / outer pouring nozzle 16 after passing through the injection port 12, the channel 14 and the discharge port 13 in turn, and finally injected into the mold 4 by the inner pouring nozzle 15 / outer pouring nozzle 16. During the injection process, since the outer pouring nozzle 16 is concentric with the inner pouring nozzle 15 and the outer pouring nozzle 16 is located on the outside of the inner pouring nozzle 15, the core material and the skin material are injected synchronously and integrally. This ensures that the core material is always in the middle of the skin material during pouring, and ensures that the skin material of the molded soft candy wraps the core material inside.

[0029] In this embodiment, the valve stem 8 includes a main rod 22 and a support rod 23. The main rod 22 is located in the quantitative cylinder 7 and slides. A deep hole is opened at one end of the main rod 22 away from the rotary valve 6. The support rod 23 is slidably arranged in the deep hole, and a tension spring 24 is connected between the end of the support rod 23 and the inner wall of the deep hole. An adjustment frame 25 is arranged on the side of the support 17. A plurality of adjustment components corresponding to each quantitative cylinder 7 are arranged on the top of the adjustment frame 25. The adjustment components include a limit seat 26 and a sliding bar 27. The upper part of the limit seat 26 is opened. A limiting opening 28 is provided, and the corresponding support rod 23 is inserted into the limiting opening 28. The size of the limiting opening 28 is larger than the size of the support rod 23 but smaller than the size of the main rod 22. The sliding bar 27 is fixedly assembled on the top of the adjustment frame 25. The bottom of the limiting seat 26 is slidably assembled on the sliding bar 27. A plurality of positioning holes 29 are evenly spaced at the top of the sliding bar 27. A positioning block 30 is movably provided at the lower part of the limiting seat 26. The positioning block 30 can be inserted into the positioning hole 29 to fix the limiting seat 26.

[0030] Because the multiple valve stems 8 are connected as a whole by the connecting frame 18 and are synchronously driven by the servo motor 20, and because the moving distance of each valve stem 8 is the same, the ratio of the skin material to the core material in the soft candies produced in the same batch can be uniform. However, when it is necessary to produce a batch of soft candies with different sandwich ratios so that the taste of the products in a package is richer, the different ratios can be adjusted by controlling the movement of the limit seat 26. After moving the corresponding limit seats 26 on both sides to the required ratio position, the positioning block 30 is pressed to insert it into the positioning hole 29 to complete the fixation. At this time, the motor drives each support rod 23 to move the same distance, but because of the limiting effect of the limit seat 26, the support rod 23 will drive the inner When the main rod 22 moves outward, it is blocked by the limit seat 26. Since the support rod 23 is connected to the main rod 22 by the tension spring 24 and has a certain movable range, it can continue to move outward. However, the main rod 22 can only move to the position of the limit seat 26 due to the blockage of the limit seat 26. Therefore, even if the servo motor 20 drives each support rod 23 to move the same distance synchronously, the position of the limit seat 26 on each support rod 23 is different, which will cause the main rod 22 therein to move a different distance, so that the amount of material drawn into the metering cylinder 7 is also different, so that the same batch can produce soft candies with different proportions of skin material and core material, thereby enriching consumers' demand for taste, without the need for production in multiple batches and then mixing and packaging, effectively improving efficiency.

[0031] In this embodiment, a plurality of first heating tubes 31 are embedded in the support 17, and the first heating tubes 31 abut against the outer wall of each metering tube 7, so as to conduct heat to the metering tube 7, a connecting seat 32 is connected between the bottoms of each rotary valve 6, each sandwich pouring nozzle 5 is arranged at equal intervals and installed at the bottom of the connecting seat 32, and the connecting pipes between the sandwich pouring nozzle 5 and the discharge port 13 are all arranged in the connecting seat 32, and a plurality of second heating tubes 33 are embedded in the connecting seat 32, and the second heating tubes 33 abut against the outer wall of the connecting pipe, so as to conduct heat to the connecting pipe; By setting the first heating tube 31 and the second heating tube 33, it can be ensured that the metering tube 7 and the sandwich pouring nozzle 5 have a certain temperature and will not be affected by external environmental factors and the temperature is low, but have a heat preservation effect, so that the core material and the skin material flowing into them will not solidify prematurely due to the temperature difference. On the one hand, it can avoid the clogging of the rotary valve 6 so that the material can flow smoothly. On the other hand, it ensures that solidification does not occur before pouring, and can also reduce the production of defective products.

[0032] In this embodiment, the hopper 3 is funnel-shaped, and a plurality of third heating tubes 34 are embedded in the outer wall of the lower inclined surface of the hopper 3. A plurality of fourth heating tubes 35 are installed on both sides of the upper inner wall of the hopper 3, and a floating frame 36 is connected between the fourth heating tubes 35 on both sides. The two ends of the floating frame 36 are respectively slidably sleeved on the outer surface of the fourth heating tube 35 on the corresponding side. A fifth heating tube 37 is arranged on the floating frame 36. The floating frame 36 can always float on the upper surface of the material under the buoyancy of the material in the hopper 3. The third heating tube 34 and the fourth heating tube 35 are provided to make the hopper 3 have a heat preservation effect, so as to prevent the material from solidifying or agglomerating in advance in the hopper 3. At the same time, since the soft candy colloidal solution has good fluidity at high temperature, the heat preservation can ensure that the material will not become viscous in the hopper 3 due to the temperature drop, so as to ensure its smooth flow out and pouring. The floating frame 36 and the fifth heating tube 37 are provided. Since the density of the floating frame 36 is much smaller than the density of the soft candy colloidal solution, the floating frame 36 can always float on the surface of the solution, so that the upper surface of the colloidal solution is heated and kept warm by the fifth heating tube 37 thereon, so as to avoid the upper surface of the solution from contacting with the air, which will cause a significant temperature difference between the surface and the interior and cause the surface to solidify. At the same time, due to the provision of the floating frame 36, the solution in the hopper 3 becomes less as the pouring, and the floating frame 36 will also drop synchronously due to the drop in liquid level, and finally stop when it drops to the inclined surface of the hopper 3, so as to avoid the floating frame 36 blocking the discharge port of the hopper 3.

[0033] In this embodiment, a cooling assembly is provided at the side end of the conveyor belt 1, and the cooling assembly is located at the downstream side of the pouring device. The cooling assembly includes a base 38, a movable frame 39, an air valve 40 and a cylinder 41. The base 38 is fixedly mounted on the side end of the conveyor belt 1, and a plurality of slide bars 42 are provided on the base 38. The movable frame 39 is slidably mounted on the slide bars 42. A spring is sleeved on the surface of each slide bar 42, and the two ends of the spring are respectively connected to the movable frame 39 and the base 38 to drive the movable frame 39 to reset. A lifting frame 50 is slidably provided at the top end of the movable frame 39. The cylinder 41 is mounted at the rear end of the movable frame 39 and the piston rod is connected to the lifting frame 50 to drive its lifting movement. A plurality of air supply pipes 44 are arranged at the bottom of the lifting frame 50. The air valve 40 is installed at the top end of the lifting frame 50. The input end of the air valve 40 is connected to an external air source, and the output end is connected to each air supply pipe 44. A fixing seat 45 is provided on one side of the mold 4 close to the cooling assembly, a ventilation cavity 46 is provided inside the mold 4, a plurality of air outlets 47 are provided on the other side of the mold 4, the air outlets 47 are connected to the ventilation cavity 46, a plurality of air supply holes 48 corresponding to the air supply pipes 44 are provided on the top of the fixing seat 45, the air supply pipes 44 can be inserted into the air supply holes 48, and the air supply holes 48 are connected to the ventilation cavity 46; In this embodiment, a plurality of air supply branch pipes 49 are provided at the front end of the lifting frame 50, and the air supply branch pipes 49 are arranged horizontally. The air supply branch pipes 49 are connected to the output end of the air valve 40. When the air supply pipe 44 is inserted into the air supply hole 48, the air supply branch pipe 49 is located above the top end of the mold 4.

[0034] The mold 4 after pouring the soft candy with the filling is continuously conveyed by the conveyor belt 1 at a set speed. When the mold 4 is conveyed to the front of the lifting frame 50, it is detected by the sensor, thereby sending a signal to the cylinder 41. The piston rod of the cylinder 41 retracts to drive the lifting frame 50 to move downward, so that each air supply pipe 44 is inserted into the corresponding air supply hole 48 at the side end of the mold 4. At the same time, the air supply branch pipe 49 is also lowered to the top surface of the mold 4 due to the lifting frame 50. At this time, the air valve 40 is opened to inject the cold air generated by the external air source into the ventilation cavity 46 through the air supply pipe 44, and then discharged from the air outlet 47. In this process, the cold air will cool the inner wall of the mold cavity of the mold 4, thereby cooling the side wall of the soft candy with the filling. At the same time, the cold air blown out of the air supply branch pipe 49 will directly blow on the surface of the soft candy with the filling. Through the coordinated work of the air supply pipe 44 and the air supply branch pipe 49, the soft candy with the filling is cooled in all directions, and the surface temperature of the soft candy is reduced in a very short time, thereby facilitating subsequent demoulding. And the cooling process can be synchronized with the pouring process, because the mold 4 is fixedly mounted on the conveyor belt 1, and when the air supply pipe 44 is inserted into the air supply hole 48 at the side end of the mold 4, it can play a role of limiting and fixing. When the pouring process is in progress, because there are multiple rows of cavities on the mold 4, and each pouring only pours one row of cavities, the conveyor belt 1 needs to continuously drive the mold 4 to move and track the sandwich pouring nozzle 5, and when the conveyor belt 1 drives the mold 4 under the pouring process, it will also synchronously drive all the molds 4 to move. At this time, the air supply pipe 4 When the mold 4 connected to the mold 4 moves, the air supply pipe 44 will synchronously drive the moving seat to move and compress the spring 43 due to the limiting effect of the air supply pipe 44, so that the air supply pipe 44 and the mold 4 are kept in a connected state, and the cooling process and the pouring process can be operated synchronously. After the pouring of one mold 4 is completed, the cooling process is completed synchronously, and the cylinder 41 drives the lifting frame 50 to move upward to make the air supply pipe 44 separate from the air supply hole 48. After separation, due to the loss of limiting force, the moving frame 39 will be reset under the rebound force of the spring 43, so that the next mold 4 can be cooled.

[0035] In this embodiment, a lifting seat 54 is movably provided on the machine 2. The lifting seat 54 is located directly below the pouring device, and its upper end is located at the lower side of the bottom of the upper conveying surface of the conveyor belt 1. A slide rail 51 and a telescopic cylinder 52 are provided on the machine 2. The lifting seat 54 moves along the slide rail 51, and the piston rod of the telescopic cylinder 52 is connected to the lifting seat 54 to drive it to move. When the conveyor belt 1 drives the mold 4 to be transported to the bottom of the sandwich pouring nozzle 5, it will be detected by the sensor, and a processing signal will be generated to the telescopic cylinder 52. The piston rod of the telescopic cylinder 52 will extend, driving the lifting seat 54 to move upward, thereby lifting the conveying surface of the conveyor belt 1 at that location, and then driving the mold 4 to push up, so that the sandwich pouring nozzle 5 extends into the mold cavity on the mold 4, and then pouring is carried out, so that the material can fall into the mold cavity accurately to avoid material splashing. After pouring is completed, the telescopic cylinder 52 is reset, and the conveyor belt 1 continues to convey.
