Description

Technical Field

[0001] The present invention relates to the technical field of quantitative pouring, and specifically relates to a soft candy sandwich quantitative integrated conveying and pouring device. Background Art

[0002] With the continuous development of the candy market, soft candy with a filling is widely loved by consumers due to its rich taste and diverse flavor combinations. The production of soft candy with a filling usually involves a double pouring process for the soft candy shell and the filling. However, there are still many deficiencies in the existing production technologies for soft candy with a filling.

[0003] Most traditional production methods for soft candy with a filling adopt a step-by-step pouring process, that is, first pouring the soft candy shell and then injecting the filling. This process has the following problems: First, the soft candy shell is prone to solidification during the movement to the filling pouring station, resulting in uneven injection of the filling, affecting product quality and qualification rate. Second, the degree of automation of the step-by-step pouring process is relatively low, and it is difficult to improve production efficiency.

[0004] In addition, although the existing equipment has achieved automated pouring, there are still defects in quantitative control, and it is impossible to accurately control the injection amounts of the filling material and the shell material, resulting in uneven ratios of the shell and the filling, inconsistent product weights and tastes, and a reduced qualification rate of the products. Summary of the Invention

[0005] The purpose of the present invention is to provide a soft candy sandwich quantitative integrated conveying and pouring device to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A soft candy sandwich quantitative integrated conveying and pouring device includes a conveyor belt, a machine platform, a pouring device, and at least two hoppers. The conveyor belt is assembled on the machine platform, and a plurality of molds are installed at equal intervals on the conveyor belt. Each of the hoppers and the pouring device are installed on the machine platform and located above the conveyor belt. Each of the hoppers is used to store different materials. The pouring device includes a plurality of filling pouring nozzles and a quantitative feeding assembly corresponding to each of the hoppers. Each feeding end in the filling pouring nozzle is respectively communicated with each quantitative feeding assembly.

[0007] The quantitative feeding assembly includes a rotary valve, a plurality of quantitative cylinders, a plurality of valve rods, and a power assembly. The rotary valve is assembled at the discharge port of the hopper to control the discharging of the hopper. The filling pouring nozzle and the quantitative cylinder are respectively communicated with the rotary valve. The valve rod is slidably arranged in the corresponding quantitative cylinder and makes a reciprocating motion driven by the power assembly. When the rotary valve switches to the state where the hopper is communicated with the quantitative cylinder, the valve rod moves to draw the material in the hopper into the quantitative cylinder. When the rotary valve switches to the state where the quantitative cylinder is communicated with the filling pouring nozzle, the valve rod moves to push the material in the quantitative cylinder into the filling pouring nozzle for discharging.

[0008] Further, the rotary valve includes a motor, a valve body and a valve core. The valve body is provided with a plurality of feeding ports, a plurality of injecting ports and a plurality of discharging ports corresponding to the number of sandwich casting nozzles along its length direction. A plurality of corresponding independent channels are arranged in the valve core. The feeding ports are communicated with the hoppers. The metering cylinders are installed at the side end of the valve body and communicated with the injecting ports.

[0012] Further, several first heating tubes are embedded inside the support, and the first heating tubes are in contact with the outer walls of the respective metering cylinders, thereby conducting heat to the metering cylinders. A connecting seat is connected between the bottoms of the respective rotary valves. Each of the sandwich pouring nozzles is arranged and installed at equal intervals at the bottom of the connecting seat. The communication pipes between the sandwich pouring nozzles and the discharge ports are all arranged inside the connecting seat. Several second heating tubes are embedded inside the connecting seat, and the second heating tubes are in contact with the outer walls of the communication pipes, thereby conducting heat to the communication pipes.

[0013] Further, the hopper is funnel-shaped. Several third heating tubes are embedded on the outer wall of the inclined surface at the lower part of the hopper.

A slide rail and a telescopic cylinder are arranged on the machine table. The lifting seat moves along the slide rail, and the piston rod of the telescopic cylinder is connected to the lifting seat to drive its movement.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. High-efficiency automated production: With the coordinated work of the unique quantitative feeding component and the sandwich pouring nozzle of the present invention, the synchronous injection and integral molding of the core material and the skin material are realized, avoiding the process complexity and time cost brought by the step-by-step processing of the core material and the skin material in the traditional production method, 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 more compact, and the sandwich is not easily displaced or leaked. This 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.

[0021] 2. Precise pouring and quality control: The device adopts advanced servo pouring technology. By controlling the moving distance of the control valve rod, the pouring amounts of the core material and the skin material can be accurately controlled to ensure that the sandwich ratio of each pouring is consistent and the product quality is stable. At the same time, through the design of the coordinated control of the conveyor belt and the lifting seat to track the movement of the sandwich pouring nozzle, problems such as sugar overflow and uneven sandwich distribution that may occur in the traditional pouring process are avoided, thereby improving the overall quality of the product.

[0022] 3. Simplified production process: The traditional production of sandwich soft candy requires complex cooling and molding processes. However, through the integrated design of this device, the pouring and cooling of the skin material and the core material are integrated in one conveyor belt, simplifying the production process, reducing the floor area of the equipment and the operation complexity. At the same time, through the unique design of the cooling component, the pouring process and the cooling process are synchronized and do not affect each other, greatly improving the production efficiency.

[0023] 4. The adjustment 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 sandwich soft candies with different sandwich amounts or sizes in the same batch of pouring. There is no need to add additional power for separate control, and only simple operation is required to switch the ratio to meet the diverse needs of the market.

[0024] 5. The design of each heating tube in the present invention can effectively maintain the temperature stability of the core material and the skin material from storage to pouring, avoid solidification or poor fluidity caused by temperature fluctuations, ensure the smoothness of the pouring process, and at the same time reduce the frequent cleaning and maintenance required due to the solidification of the core material or the thickening of the skin material. This not only reduces the production cost but also improves the service life of the equipment. Description of the Drawings

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] As Figures 1 to 10 shown, a soft candy sandwich quantitative integrated conveying and pouring device includes a conveyor belt 1, a machine table 2, a pouring device, and at least two hoppers 3. The conveyor belt 1 is assembled on the machine table 2, and a plurality of molds 4 are equidistantly installed on the conveyor belt 1. Each hopper 3 and the pouring device are installed on the machine table 2 and located above the conveyor belt 1. Each hopper 3 is used to store different materials. The pouring device includes several sandwich pouring nozzles 5 and a quantitative feeding assembly corresponding to each of the several hoppers 3, and each feeding end in the sandwich pouring nozzle 5 is respectively communicated with each quantitative feeding assembly.

[0038] The quantitative feeding assembly includes a rotary valve 6, several quantitative cylinders 7, several valve rods 8, and a power assembly. The rotary valve 6 is assembled at the discharge port of the hopper 3 to control the feeding of the hopper 3. The sandwich pouring nozzle 5 and the quantitative cylinder 7 are respectively communicated with the rotary valve 6. The valve rod 8 is slidably arranged in the corresponding quantitative cylinder 7 and makes a reciprocating motion under the drive of the power assembly. When the rotary valve 6 is switched to the state where the hopper 3 is communicated with the quantitative cylinder 7, the valve rod 8 moves to suck 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 is communicated with the sandwich pouring nozzle 5, the valve rod 8 moves to push the material in the quantitative cylinder 7 into the sandwich pouring nozzle 5 for discharge.

[0039] 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 several feeding ports 11, several injection ports 12, and several discharging ports 13 corresponding to the number of sandwich pouring nozzles 5 along its length direction. Several corresponding independent channels 14 are arranged in the valve core 10. The feeding port 11 is communicated with the hopper 3. The quantitative cylinder 7 is installed at the side end of the valve body 9 and communicated with the injection port 12. The discharging port 13 is communicated with 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 has two states: the first state, both ends of the channel 14 are respectively communicated with the corresponding feeding port 11 and injection port 12; the second state, both ends of the channel 14 are respectively communicated with the corresponding injection port 12 and discharging port 13.

[0040] In this embodiment, there are two sets of hoppers 3 and quantitative feeding components respectively. The two sets of hoppers 3 are used to store skin materials and core materials. The sandwich pouring nozzle 5 includes a pouring inner nozzle 15 and a pouring outer nozzle 16. The pouring inner nozzle 15 is arranged inside the pouring outer nozzle 16, and the height of the discharge port of the pouring inner nozzle 15 is higher than that of the discharge port of the pouring outer nozzle 16. This design can ensure that the skin material is injected before the core material, so as to ensure that the skin material can wrap the core material. Each discharge port 13 of the valve body 9 for conveying the skin material is respectively communicated with the feeding end of the corresponding pouring outer nozzle 16, and each discharge port 13 of the valve body 9 for conveying the core material is respectively communicated with the feeding end of the corresponding pouring inner nozzle 15.

[0041] In this embodiment, the number of the metering cylinders 7 corresponds to the number of the sandwich pouring nozzles 5. A support 17 is arranged at the side end of the valve body 9, and each metering cylinder 7 is equally spaced and embedded in the support 17. A seal 53 is arranged at one end of the valve stem 8 close to the rotary valve 6. One end of the valve stem 8 in each metering cylinder 7 far from the rotary valve 6 extends out of the metering cylinder 7, and a connecting frame 18 is connected to the end of each valve stem 8. A rack 19 is arranged at the side end of the connecting frame 18. The power assembly includes a servo motor 20 and a gear 21 installed on the output shaft of the servo motor 20. The gear 21 is meshed with the rack 19, so that the servo motor 20 can drive all the valve stems 8 to move synchronously.

[0042] The pouring process of this device is as follows (taking a single sandwich pouring nozzle 5 as an example for illustration): The staff first pour the core material as the sandwich and the skin material as the shell into the two hoppers 3 respectively. The conveyor belt 1 conveys the mold 4 to the sandwich pouring nozzle 5. At this time, the rotary valve 6 switches to the first state, and the servo motors 20 on both sides run synchronously. The servo motor 20 drives the valve stem 8 to move outwards through the meshing action of the gear 21 and the rack 19. Thus, under the action of atmospheric pressure, the core material / skin material in the hopper 3 flows through the feeding port 11, the channel 14 and the injection port 12 in sequence and is pumped into the metering cylinder 7. The amount of the pumped material can be controlled by the moving distance of the valve stem 8, so as to achieve the effect of quantitative feeding. Then the rotary valve 6 switches to the second state, and the servo motor 20 drives the valve stem 8 to move inwards, and the material in the metering cylinder 7 flows through the injection port 12, the channel 14 and the discharge port 13 in sequence and is pushed into the corresponding pouring inner nozzle 15 / pouring outer nozzle 16. Finally, it is injected into the mold 4 by the pouring inner nozzle 15 / pouring outer nozzle 16. And during the injection process, since the pouring outer nozzle 16 and the pouring inner nozzle 15 are concentric and the pouring outer nozzle 16 is located outside the pouring inner nozzle 15, the core material and the skin material are injected synchronously as a whole, so that it can be ensured that the core material is always in the middle of the skin material during pouring, and the formed soft candy skin material wraps the core material inside.

[0043] In this embodiment, the valve rod 8 includes a main rod 22 and a support rod 23. The main rod 22 is located inside the metering cylinder 7 and slides therein. A deep hole is formed at one end of the main rod 22 away from the rotary valve 6. The support rod 23 is slidably disposed 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 provided on the side of the support 17. A plurality of adjustment components corresponding to each metering cylinder 7 are provided at the top of the adjustment frame 25. The adjustment component includes a limit seat 26 and a sliding strip 27. A limit opening 28 is formed in the upper part of the limit seat 26. The corresponding support rod 23 passes through the limit opening 28. The size of the limit opening 28 is larger than the size of the support rod 23 and smaller than the size of the main rod 22. The sliding strip 27 is fixedly assembled on the top of the adjustment frame 25. The bottom of the limit seat 26 is slidably assembled on the sliding strip 27. A plurality of positioning holes 29 are equidistantly formed at the top of the sliding strip 27. A positioning block 30 is movably provided at the lower part of the limit seat 26. The positioning block 30 can be inserted into the positioning hole 29 to fix the limit seat 26.

[0044] Since multiple valve rods 8 are connected into one body by the connecting frame 18 and are synchronously driven by the servo motor 20, and since the moving distance of each valve rod 8 is the same, the ratio of the skin material and the core material in the gummy candies produced in the same batch can be made uniform. However, when it is necessary to produce gummy candies with different sandwich ratios in one batch to make the taste of the products in one package richer, at this time, the ratio 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 positions, press the positioning block 30 to make it insert into the positioning hole 29 to complete the fixation. At this time, the motor drives each support rod 23 to move the same distance. However, due to the limiting effect of the limit seat 26, when the support rod 23 drives the main rod 22 inside it to move outward, it will be 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 movement 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 synchronously the same distance, due to the different positions of the limit seats 26 on each support rod 23, the moving distances of the main rods 22 inside them are different, so the amount of material drawn into the metering cylinder 7 is also different, enabling gummy candies with different ratios of skin material and core material to be produced in the same batch, thus enriching the consumers' taste requirements, without the need to produce in multiple batches and then mix and package them, effectively improving the efficiency.

[0045] In this embodiment, several first heating tubes 31 are embedded inside the support 17, and the first heating tubes 31 are in contact with the outer walls of the respective metering cylinders 7, so as to conduct heat to the metering cylinders 7. A connecting seat 32 is connected between the bottoms of the respective rotary valves 6. The respective sandwich pouring nozzles 5 are arranged and installed at equal intervals at the bottom of the connecting seat 32. The communication pipes between the sandwich pouring nozzles 5 and the discharge ports 13 are all arranged inside the connecting seat 32. Several second heating tubes 33 are embedded inside the connecting seat 32, and the second heating tubes 33 are in contact with the outer walls of the communication pipes, so as to conduct heat to the communication pipes;

[0046] Through the arrangement of the first heating tubes 31 and the second heating tubes 33, it can be ensured that the metering cylinders 7 and the sandwich pouring nozzles 5 have a certain temperature and will not have a low temperature due to external environmental factors, but have a heat preservation effect, so that the core material and the skin material flowing into them will not solidify in advance due to the temperature difference. On the one hand, it can prevent the rotary valves 6 from being blocked and enable the materials to flow smoothly. On the other hand, it can ensure that there is no solidification before pouring and can also reduce the generation of defective products.

[0047] In this embodiment, the hopper 3 is in a funnel shape. Several third heating tubes 34 are embedded on the outer wall of the inclined surface at the lower part of the hopper 3. Several fourth heating tubes 35 are installed on the left and right sides of the inner wall of the upper part of the hopper 3. 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 surfaces of the corresponding fourth heating tubes 35 on one 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;

[0048] The arrangement of the third heating tubes 34 and the fourth heating tubes 35 can make the hopper 3 play a role in heat preservation, prevent the materials from solidifying or agglomerating in advance in the hopper 3. At the same time, since the soft candy colloid solution has good fluidity at high temperatures, heat preservation can ensure that the materials in the hopper 3 will not become viscous due to temperature drop, so as to ensure its smooth outflow and pouring; and the arrangement of the floating frame 36 and the fifth heating tube 37. Since the density of the floating frame 36 is much smaller than the density of the soft candy colloid solution, the floating frame 36 can always float on the surface of the solution, so as to heat and keep warm the upper surface of the colloid solution through the fifth heating tube 37 thereon, avoiding the surface of the solution from solidifying due to the obvious temperature difference between the surface and the inside caused by contact with the air. At the same time, due to the arrangement of the floating frame 36, as the solution in the hopper 3 becomes less during pouring, the floating frame 36 will also drop synchronously as the liquid level drops and finally stop at the inclined surface of the hopper 3 to avoid the floating frame 36 from blocking the discharge port of the hopper 3.

[0049] In this embodiment, a cooling component is provided at the side end of the conveyor belt 1, and the cooling component is located on the downstream side of the pouring device. The cooling component includes a base 38, a moving frame 39, an air valve 40, and a cylinder 41. The base 38 is fixedly assembled at the side end of the conveyor belt 1. A plurality of sliding rods 42 are provided on the base 38. The moving frame 39 is slidably assembled on the sliding rods 42. Springs are sleeved on the surfaces of the respective sliding rods 42, and the two ends of the springs are respectively connected to the moving frame 39 and the base 38 to drive the moving frame 39 to reset. A lifting frame 50 is slidably provided at the top end of the moving frame 39. The cylinder 41 is assembled at the rear end of the moving 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 in a row 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 the respective air supply pipes 44;

[0050] A fixed seat 45 is provided on one side of the mold 4 close to the cooling component. An air vent cavity 46 is formed inside the mold 4. A plurality of air outlet holes 47 are formed on the other side of the mold 4. The air outlet holes 47 are connected to the air vent cavity 46. A plurality of air supply holes 48 corresponding to the respective air supply pipes 44 are formed at the top end of the fixed seat 45. The air supply pipes 44 can be inserted into the air supply holes 48. The air supply holes 48 are connected to the air vent cavity 46;

[0051] 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 horizontally arranged. The air supply branch pipes 49 are connected to the output end of the air valve 40. When the air supply pipes 44 are inserted into the air supply holes 48, the air supply branch pipes 49 are located above the top of the mold 4.

[0052] After the mold 4 for pouring the jelly soft candy is completed, it continues to be 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, and thus a signal is sent to the cylinder 41. The piston rod of the cylinder 41 retracts to drive the lifting frame 50 to move downward, so that the respective air supply pipes 44 are inserted into the corresponding air supply holes 48 on the side end of the mold 4. At the same time, the air supply branch pipes 49 also reach the top surface of the mold 4 due to the downward movement of 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 air vent cavity 46 through the air supply pipes 44 and then discharged from the air outlet holes 47. During this process, the cold air will cool the inner wall of the cavity of the mold 4, thereby cooling the side wall of the jelly soft candy. At the same time, the cold air blown out by the air supply branch pipes 49 will directly blow the surface of the jelly soft candy. Through the coordinated work of the air supply pipes 44 and the air supply branch pipes 49, the jelly soft candy is cooled in all directions, and the surface temperature of the soft candy is reduced in a very short time, so as to facilitate subsequent demolding;

[0053] Moreover, this cooling process can run synchronously with the pouring process. Since the mold 4 is fixedly installed on the conveyor belt 1, when the air supply pipe 44 is inserted into the air supply hole 48 on the side end of the mold 4, it can play a role in limiting and fixing. When the pouring process is carried out, because there are multiple rows of mold cavities on the mold 4, and only one row of mold cavities is poured each time, the conveyor belt 1 needs to continuously drive the mold 4 to move and track the sandwich pouring nozzle 5. When the conveyor belt 1 drives the mold 4 in the pouring process, it will also drive all the molds 4 to move synchronously. At this time, when the mold 4 connected to the air supply pipe 44 moves, it will 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 remains in communication with the mold 4. The cooling process and the pouring process can run synchronously. After the pouring of a piece of mold 4 is completed, the cooling process is completed synchronously. The air cylinder 41 drives the lifting frame 50 to move upward, so that the air supply pipe 44 is separated from the air supply hole 48. After separation, due to the loss of the limiting force, the moving frame 39 will reset under the resilience of the spring 43, so as to cool the next piece of mold 4.

[0054] In this embodiment, a lifting seat 54 is movably arranged on the machine table 2. The lifting seat 54 is located directly below the pouring device, and its upper end is located below the bottom of the upper conveying surface of the conveyor belt 1. A slide rail 51 and a telescopic cylinder 52 are arranged on the machine table 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 its movement;

[0055] When the conveyor belt 1 drives the mold 4 to be conveyed below the sandwich pouring nozzle 5, it will be detected by the sensor, and at the same time, a processing signal is sent to the telescopic cylinder 52. The piston rod of the telescopic cylinder 52 extends, driving the lifting seat 54 to move upward, thereby lifting the conveying surface at this place of the conveyor belt 1, and then driving the mold 4 to move upward, 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 accurately fall into the mold cavity to avoid material splashing. After pouring is completed, the telescopic cylinder 52 resets, and the conveyor belt 1 continues to convey.
