Description

Technical Field

[0001] The present invention relates to the technical field of candy packaging, and in particular to a candy quantitative packaging device and a production system. Background Art

[0002] Candy filling is a core process in packaging. In the existing candy production and packaging industry, quantitative filling of liquid and semi-liquid candies (syrups) has always faced numerous technical challenges. Currently, common quantitative filling devices on the market mainly use the following technical solutions: First, filling systems based on electronic flow meters can achieve quantitative control, but they have disadvantages such as the sensor being easily affected by syrup viscosity and high maintenance costs;

[0003] Secondly, mechanical plunger pump filling equipment, while relatively simple in structure, suffers from low refill efficiency, particularly when handling high-viscosity syrups, which are prone to flow interruption. These existing equipment generally lack effective refill systems, resulting in poor filling continuity and limited production efficiency.

[0004] In addition, the nozzles of candy quantitative packaging devices mostly adopt an integral design. The integral design requires replacing the entire filling unit when part of it is damaged, which results in high maintenance costs. Summary of the Invention

[0005] In view of this, the object of the present invention is to provide a candy quantitative packaging device and production system, whose filling unit can quickly refill while ensuring filling accuracy, and the filling unit has a modular design to achieve rapid replacement of a single nozzle to solve the technical problems described in the background technology.

[0006] The present invention is achieved through the following technical solutions:

[0007] A candy quantitative packaging device includes a storage tank containing syrup, a plurality of feed pipes connected to the bottom of the storage tank, the other ends of the feed pipes being connected to an outer frame, and a plurality of filling components arranged in the outer frame along the length direction of the outer frame;

[0008] Each group of the filling components includes a filling head with a nozzle, the filling head is fixedly connected to the outer frame, the top of the filling head is fixedly connected to a fixed head, a sleeve is fixedly provided on the side of the fixed head away from the filling head, and a material preparation cavity is provided inside the filling head to connect the nozzle, the material pipe and the sleeve;

[0009] The internal sliding seal of the sleeve is equipped with a piston rod A. The upper ends of multiple piston rods A extend out of the sleeve and are connected to a supporting plate. The supporting plate is connected to a power source for driving the supporting plate to rise and fall.

[0010] Furthermore, the output end of the power source is fixedly connected to a connecting plate, the connecting plate is vertically fixedly connected to a sliding rod, and the lower end of the sliding rod is fixedly connected to the supporting plate;

[0011] A support ear is fixed on the outside of the slide rod, and a piston rod B is fixed on the other end of the support ear. The center line of the piston rod B is parallel to the center line of the slide rod;

[0012] An air cylinder is fixedly provided outside the material storage tank, and the piston rod B is slidingly and sealingly assembled in the air cylinder, and the output end of the air cylinder is communicated with the interior of the material storage tank.

[0013] Furthermore, the power source is mounted on a top plate, the slide rod is vertically slidably connected to the top plate, the bottom of the top plate is fixedly connected to a vertical rod, and the lower end of the vertical rod is fixedly connected to the bottom plate;

[0014] The bottom of the bottom plate and the bottom of the outer frame are both provided with an escape opening, and the width of the escape opening is greater than the diameter of the nozzle.

[0015] Furthermore, the bottom inner wall of the outer frame is provided with a plurality of positioning protrusions for positioning and installing the filling heads; an operating space is formed between two adjacent filling heads, and finger grooves are respectively provided on both sides of the filling heads.

[0016] Furthermore, a through slot is provided on the top of the outer frame and a positioning hole is provided on the top of the filling head to communicate with the material preparation cavity.

[0017] The fixing head includes an integrally formed positioning head, a positioning plate and a fixing plate. The positioning head and the positioning plate are plugged into and matched with the positioning hole and the through slot respectively. The fixing plate is fixedly connected to the sleeve.

[0018] Furthermore, a limiting hole A is provided on the inner wall of the bottom of the outer frame, a spring is fixed on the bottom wall of the limiting hole A, a limiting block is fixed on the upper end of the spring, and a limiting hole B is provided on the bottom wall of the filling head to be plugged into the limiting block.

[0019] Furthermore, the upper end of the material pipe is perpendicular to the material storage tank, and the angle between the material pipe and the side of the outer frame is between ten and thirty degrees.

[0020] Furthermore, the inner wall of the material tube is spiral, the spiral angle is between fifteen and twenty-five degrees, and the inlet pitch is greater than the outlet pitch.

[0021] A production system includes the candy quantitative packaging device as described above, wherein a mounting plate is fixedly connected to the bottom of the base plate, the storage tank is mounted on a mounting frame, the mounting plate and the mounting frame are jointly connected to a conveying frame, and a plurality of templates are installed on the conveying frame, and a plurality of molds are installed in the templates.

[0022] The beneficial effects of the present invention are:

[0023] 1. The present invention's sliding rod, driven by the power source, synchronously controls the injection and suction actions of piston rod A as it reciprocates upward and downward, achieving integrated filling and feeding operations, resulting in a compact and stable packaging device. The negative pressure suction generated by the upward movement of piston rod A, combined with gravity, ensures rapid replenishment of syrup into the preparation chamber (at a flow rate of up to 1.5 m / s). This system is particularly suitable for the continuous filling of high-viscosity syrups and high-viscosity sugar solutions containing 20-30% particles sized at (1-2) mm by (1-1.5) mm by (1-1.5) mm.

[0024] 2. This invention features a bidirectional powered feeding system. When the same power source drives the slide rod upward, piston rod B injects gas into the storage tank to create positive pressure. This, in synergy with the negative pressure generated by piston rod A, propels the syrup from the storage tank through the feed pipe into the preparation chamber at a speed of 1.5 m / s (a 90% increase compared to a single negative pressure system). This structure further addresses the issue of delayed feeding for high-viscosity syrups and high-viscosity sugar solutions containing particles.

[0025] 3. The present invention controls the syrup injection volume through mechanical stroke limit, with an error of ≤±0.5% (standard deviation of 50mL filling volume ±0.25). In addition, each group of independent filling components and the material pipes connected thereto cooperate to form multiple sets of independent and non-interfering filling structures, further ensuring the filling accuracy. Secondly, the closed filling channel formed by the connection can effectively prevent external contamination during the syrup filling process.

[0026] 4. The modular design of the filling assembly of this invention allows for quick-release nozzle installation, enabling independent disassembly and maintenance of individual components. Furthermore, nozzles of varying specifications can be quickly disassembled and replaced to suit different pouring requirements, saving time on cleaning and other maintenance. The entire system boasts a simple and reliable structure, ensuring filling accuracy while maintaining high efficiency and hygiene, making it particularly suitable for quantitative packaging of various liquid or semi-liquid candies.

DETAILED DESCRIPTION

[0036] Typical embodiments that embody the features and advantages of the present invention are described in detail in the following description. It should be understood that the present invention is capable of various variations in different embodiments without departing from the scope of the present invention, and that the descriptions and illustrations are intended to be illustrative rather than limiting.

[0037] In the description of this application, the terms "upper" and "lower" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. These are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on this application.

[0038] See also Figures 1 to 4The present invention provides a technical solution: a candy quantitative packaging device, comprising a storage tank 1 with syrup stored therein, a plurality of material pipes 2 connected to the bottom of the storage tank 1, the tops of the plurality of material pipes 2 are at the same horizontal height, and the upper ends of the material pipes 2 are perpendicular to the storage tank 1, and the other ends of the material pipes 2 are commonly connected to an outer frame 3, one of the side portions in the length direction of the outer frame 3 is open, the material pipes 2 are fixedly connected to the back of the outer frame 3 and extend into the outer frame 3, and the angle between the material pipes 2 and the side portion of the outer frame 3 is between ten and thirty degrees, which is conducive to the syrup inside the storage tank 1 flowing out through the material pipes 2.

[0039] See also Figures 1 to 3 Along the length direction of the outer frame 3, multiple groups of filling components 4 are arranged in the outer frame 3. Each group of the filling components 4 includes a filling head 42 with a nozzle 41. The nozzle 41 adopts a one-way valve nozzle in the prior art. The high-pressure liquid pushes the valve core to spray out, and the spring 24 resets and seals when the pressure is low. The filling head 42 is fixed to the outer frame 3 by screws.

[0040] The bottom inner wall of the outer frame 3 is provided with a plurality of positioning protrusions 14 for positioning and installing the filling head 42. When the filling head 42 is inserted between two of the positioning protrusions 14, the filling head 42 is directly opposite the lower outlet of the material pipe 2, so that the filling head 42 is plugged and connected with the material pipe 2. The bottom of the outer frame 3 is provided with an avoidance opening 13. The width of the avoidance opening 13 is greater than the diameter of the nozzle 41, which is conducive to the installation of the nozzle 41 following the filling head 42.

[0041] See also Figure 2 An operating space 15 is formed between two adjacent filling heads 42. Finger grooves 16 are provided on both sides of the filling heads 42. The spacing between the two filling heads 42 provides operating space for installing or removing the filling heads 42. The finger grooves 16 facilitate the removal or installation of the filling heads 42 when the filling heads 42 are released. This makes the nozzle 41 detachable and can be removed separately for replacement or maintenance. In addition, a sealing structure commonly used in the prior art (not shown) can be provided at the connection between the filling head 42 and the material pipe 2. For example, an annular groove can be machined on the end surface of the filling head 42 or the lower end of the material pipe 2 and an "O" ring (materials such as nitrile rubber, fluororubber, etc.) is embedded to ensure the sealing between the filling head 42 and the material pipe 2.

[0042] See also Figure 6A limiting hole A23 is provided on the bottom inner wall of the outer frame 3, and a spring 24 is fixed on the bottom wall of the limiting hole A23. A limiting block 25 is fixed on the upper end of the spring 24. A limiting hole B26 is provided on the bottom wall of the filling head 42 to be plugged into and cooperate with the limiting block 25. When the filling head 42 is inserted into the space between the two positioning protrusions 14, the filling head 42 squeezes the limiting block 25. Subsequently, when the filling head 42 moves so that the limiting block 25 is aligned with the limiting hole B26, the limiting block 25 extends into the limiting hole B26 under the force generated by the deformation of the spring 24 back to its original state, thereby limiting the movement of the filling head 42. At this time, the filling head 42 reaches the installation position, and finally the filling head 42 is fixed to the top of the outer frame 3 by screws. After the screws fixing the filling head 42 are released, the filling head 42 can again press the limiting block 25 downward under the action of an external force, so that the filling head 42 can be disassembled.

[0043] See also Figure 2 and Figure 3 The top of the filling head 42 is fixedly connected to a fixed head 44, and a sleeve 45 is fixedly provided on the side of the fixed head 44 away from the filling head 42. A through slot 19 is provided on the top of the outer frame 3 from top to bottom, and a positioning hole 18 is provided on the top of the filling head 42 to communicate with the material preparation chamber 43 from top to bottom;

[0044] The fixed head 44 includes an integrally formed positioning head 20, a positioning plate 21 and a fixing plate 22. The positioning head 20 and the positioning plate 21 are respectively plugged into the positioning hole 18 and the through slot 19. The fixing plate 22 is welded and fixed to the sleeve 45. The fixed head 44 passes through the through slot 19 and is plugged into the filling head 42. This not only allows the filling head 42 to be positioned and installed, but also modularizes the filling head 42 and the fixing head 44. Any one of the filling components 4 can be disassembled and maintained separately, especially when the nozzle 41 is blocked by syrup or the nozzle 41 of a different specification needs to be replaced.

[0045] See also Figures 1 to 3The interior of the filling head 42 is provided with a preparation chamber 43 which is connected to the nozzle 41, the material pipe 2 and the sleeve 45. The internal sliding seal of the sleeve 45 is equipped with a piston rod A46. The upper ends of multiple piston rods A46 extend out of the sleeve and are connected to a support plate 47. The support plate 47 is connected to a power source 48 for driving the support plate 47 to rise and fall. The power source 48 adopts a cylinder, and other structures in the prior art that can achieve the same purpose can also be adopted. When the power source 48 is working, the support plate 47 rises or falls under the action of the power source 48. At this time, the multiple piston rods A46 follow the movement of the support plate 47. When the piston rod A46 moves downward, the syrup entering the preparation chamber 43 can be squeezed out through the nozzle 41 for filling and packaging. When the piston rod A46 moves upward, the syrup in the material pipe 2 flows into the preparation chamber 43 and is replenished. In addition, the piston rod A46 can generate suction during the upward movement to further accelerate the speed at which the syrup flows into the preparation chamber 43.

[0046] See also Figure 1 The output end of the power source 48 is fixedly connected to a connecting plate 5, and a sliding rod 6 is vertically fixedly connected to the connecting plate 5. The lower end of the sliding rod 6 is fixedly connected to the supporting plate 47. In this design, when the output end of the power source 48 is in motion, the supporting plate 47 can be driven to rise or fall through the cooperation of the connecting plate 5 and the sliding rod 6.

[0047] See also Figure 1 The power source 48 is installed on a top plate 10, the slide rod 6 is vertically slidably connected to the top plate 10, the bottom of the top plate 10 is fixedly connected to the vertical rod 11, and the lower end of the vertical rod 11 is fixedly connected to the bottom plate 12, thereby installing the power source 48 and the slide rod 6 and other structures.

[0048] Secondly, the bottom plate 12 is provided with the same avoidance opening 13 as that on the outer frame 3 , so as to facilitate the installation of the nozzle 41 .

[0049] See also Figure 5, the slide rod 6 is fixedly provided with a support ear 7, and the other end of the support ear 7 is fixedly provided with a piston rod B8, the center line of the piston rod B8 is parallel to the center line of the slide rod 6, and the storage tank 1 is fixedly provided with an inflation cylinder 9, the piston rod B8 is slidingly and sealingly assembled in the inflation cylinder 9, the output end of the inflation cylinder 9 is connected with the interior of the storage tank 1, and a one-way valve (not shown) is installed at the output end of the inflation cylinder 9. When the power source 48 drives the slide rod 6 to move downward and pushes the piston rod A46 to move downward for filling, the piston rod B8 slides downward to draw the external gas into the inflation cylinder 9. In the process of resetting the slide rod 6, the piston rod A46 not only draws the syrup into the preparation chamber 43, but also the piston rod B8 resets to fill the gas in the inflation cylinder 9 into the storage tank 1, and the syrup in the storage tank 1 is introduced into the material pipe 2.

[0050] In addition, a gas purifier and a one-way valve structure (not shown) are installed at the input end (air inlet end) of the inflation cylinder 9 to control the one-way flow of gas, and the gas is filled into the storage tank 1 after purification, thereby reducing the risk of contamination of the syrup discharge.

[0051] See also Figure 1 The storage tank 1 is provided with a feeding pipe 34 and an exhaust pipe 35, which are respectively used to add syrup to the storage tank 1. The exhaust pipe 35 is used to exhaust the air inside the storage tank 1 before adding the syrup. The exhaust pipe 35 is installed with a solenoid valve for opening or closing the exhaust pipe 35, and the storage tank 1 is installed with a sensor, which monitors the material level in the storage tank 1 by ultrasonic means to facilitate timely feeding. Its specific control method and structure have been relatively mature in the existing technology and will not be described in detail here.

[0052] The inner wall of the material tube 2 is spiral, and its spiral angle is between fifteen and twenty-five degrees (if the angle is too small, the separation force is insufficient, and if it is too large, the pressure loss increases), and the inlet pitch is greater than the outlet pitch. The spiral gradient pitch design can avoid sudden changes in flow rate and prevent new bubbles from being generated by shearing.

[0053] The spiral pipe structure forces the syrup to do spiral motion, reducing gas rolls, sucking bubbles with low density, and gathering them toward the center of the spiral under the action of centrifugal force, reducing the outflow of gas and syrup together during filling, ensuring filling accuracy, and is especially suitable for syrups with high viscosity or those sensitive to bubbles (such as inflated candies and transparent hard syrups).

[0054] See also Figure 4 A valve A32 is installed at the connection between the material pipe 2 and the storage tank 1 to prevent syrup from flowing back. A valve B33 is installed at one end of the material pipe 2 connected to the outer frame 3. The valve B33 is used to open or close the material pipe 2 and can be used during maintenance.

[0055] The working principle of the present invention is as follows: when the syrup is being filled and packaged, the power source 48 is actuated to drive the slide bar 6 to slide downward. On the one hand, when the slide bar 6 slides downward, it drives the support plate 47 to move. When the support plate 47 moves downward, it drives the multiple piston rods A46 to move downward together to perform an injection action, so that the syrup in the preparation chamber 43 is poured downward through the nozzle 41 for filling. On the other hand, when the slide bar 6 slides downward, it drives the piston rod B8 to move downward through the support ear 7, thereby sucking the external gas into the inflation cylinder 9.

[0056] After one filling is completed, the slide rod 6 moves upward and resets under the action of the power source 48. When the slide rod 6 moves upward and resets, on the one hand, the piston rod A46 sucks in the preparation chamber 43 to generate negative pressure when it resets upward, and the syrup in the material pipe 2 flows into the preparation chamber 43 under the action of gravity and suction. On the other hand (at the same time), the piston rod B8 resets and injects the gas entering the inflation cylinder 9 into the storage tank 1. At this time, the valve A32 opens, and the syrup in the storage tank 1 is replenished and injected into the material pipe 2. By setting the power source 48 to drive the movable stroke of the slide rod 6, the volume of the syrup entering the preparation chamber 43 can be controlled to achieve quantitative packaging of candies (liquid or semi-liquid).

[0057] See also Figure 7 , a production system includes the candy quantitative packaging device as described above, the bottom of the base plate 12 is fixedly connected to a mounting plate 27, the storage tank 1 is mounted on a mounting frame 28, the mounting plate 27 and the mounting frame 28 are jointly connected to a conveying frame 29, so that the candy quantitative packaging device is installed on the packaging line, and a plurality of templates 30 are installed on the conveyor belt of the conveying frame 29, and a plurality of molds 31 are installed in the templates 30. Two sets of quantitative packaging devices can be arranged symmetrically on the storage tank 1, and can cooperate to simultaneously pour and fill two rows of multiple molds 31, thereby improving production efficiency. The specific conveying structure of the conveying frame 29 has been relatively mature in the existing technology and will not be described in detail here. After filling, the candy is transported to the next process through the conveyor belt for printing and packaging.

[0058] Finally, it should be noted that the above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
