Description

Technical Field

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

[0002] The filling of candies is the core link of packaging. In the existing field of candy production and packaging, the quantitative filling of liquid and semi-liquid candies (syrups) has always faced many technical challenges. The common quantitative filling devices on the market mainly adopt the following technical solutions: One is the filling system based on an electronic flowmeter. Although it can achieve quantitative control, it has disadvantages such as the sensor being easily affected by the viscosity of the syrup and high maintenance costs. The second is the mechanical plunger pump filling equipment. Although its structure is relatively simple, the feeding efficiency is low, and especially when dealing with high-viscosity syrup, it is prone to flow interruption. These existing devices generally lack an effective feeding system, resulting in poor filling continuity and limited production efficiency.

[0003] In addition, most of the nozzles of the candy quantitative packaging device adopt an integral design. The integral design makes it necessary to replace the entire filling unit when a local damage occurs, resulting in high maintenance costs. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a candy quantitative packaging device and a production system, whose filling unit can quickly feed while ensuring filling accuracy, and the filling unit is modularly designed to achieve quick replacement of a single nozzle, so as to solve the technical problems described in the background art.

[0005] The present invention is achieved through the following technical solutions: A candy quantitative packaging device includes a storage tank internally storing syrup. The bottom of the storage tank is connected with a plurality of material pipes, and the other ends of the material pipes are commonly connected to an outer frame. Along the length direction of the outer frame, a plurality of groups of filling assemblies are arranged in the outer frame. Each group of the filling assemblies 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 with a fixed head. A sleeve is fixedly provided on the side of the fixed head away from the filling head. A stock preparation cavity communicating with the nozzle, the material pipe and the sleeve is opened inside the filling head. A piston rod A is slidably and sealingly assembled inside the sleeve. The upper ends of the plurality of piston rods A extend out of the sleeve and are commonly connected to a tray. A power source for driving the tray to lift is connected to the tray.

[0006] Further, the output end of the power source is fixedly connected with a connecting plate. A sliding rod is vertically fixedly connected to the connecting plate. The lower end of the sliding rod is fixedly connected to the tray. An ear support is fixedly arranged outside the sliding rod, and a piston rod B is fixedly arranged at the other end of the ear support. The central axis of the piston rod B is parallel to the central axis of the sliding rod; An air cylinder is fixedly arranged outside the storage tank. The piston rod B is slidably and sealingly assembled in the air cylinder, and the output end of the air cylinder is communicated with the inside of the storage tank.

[0007] Furthermore, the power source is installed on a top plate. The sliding rod is vertically slidably connected to the top plate. A vertical rod is fixedly connected to the bottom of the top plate, and a bottom plate is fixedly connected to the lower end of the vertical rod; Avoidance openings are formed at the bottoms of the bottom plate and the outer frame respectively, and the width of the avoidance opening is greater than the diameter of the nozzle.

[0008] Furthermore, a plurality of positioning protrusions are provided on the inner wall of the bottom of the outer frame for positioning and installing the filling heads; an operation space is formed at intervals between two adjacent filling heads, and finger grooves are respectively formed on both sides of the filling head.

[0009] Furthermore, a through groove is formed through the top and bottom of the top of the outer frame, and a positioning hole communicating the material preparation cavity up and down is formed at the top of the filling head; The fixed head includes a positioning head, a positioning plate and a fixing plate which are integrally formed. The positioning head and the positioning plate are respectively inserted and matched with the positioning hole and the through groove, and the fixing plate is fixedly connected to the sleeve.

[0010] Furthermore, a limiting hole A is formed on the inner wall of the bottom of the outer frame. A spring is fixedly arranged on the bottom wall of the limiting hole A, and a limiting block is fixedly arranged at the upper end of the spring. A limiting hole B inserted and matched with the limiting block is formed on the bottom wall of the filling head.

[0011] Furthermore, the upper end of the material pipe is perpendicular to the storage tank, and the included angle between the material pipe and the side part of the outer frame is between 10 and 30 degrees.

[0012] Furthermore, the inner pipe wall of the material pipe is spiral, the spiral angle is between 15 and 25 degrees, and the inlet pitch is greater than the outlet pitch.

[0013] A production system includes the candy quantitative packaging device as described above. An installation plate is fixedly connected to the bottom of the bottom plate. The storage tank is installed on an installation frame. The installation plate and the installation 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.

[0014] The beneficial effects of the present invention are as follows: 1. When the sliding rod of the present invention reciprocates up and down under the action of the power source, it can synchronously control the injection and suction actions of the piston rod A, realizing the integrated operation of filling and feeding, making the structure of the packaging device compact and the operation stable. Through the combined action of the negative pressure suction force generated by the movement of the piston rod A driven by the rising of the sliding rod and gravity, it is ensured that the syrup is quickly replenished into the stock preparation chamber (the flow rate can reach 1.5 m / s), which is especially suitable for the continuous filling of high-viscosity syrup and high-viscosity sugar solution containing 20 - 30% particles with a size of (1~2) mm * (1 ~1.5) mm * (1~1.5) mm.

[0015] 2. The present invention has a two-way power feeding system. When the same power source drives the sliding rod to rise, the piston rod B injects gas into the storage tank to establish a positive pressure, which forms a synergistic effect with the negative pressure generated by the piston rod A, and pushes the syrup to flow from the storage tank into the stock preparation chamber through the material pipe at a speed of 1.5 m / s (90% higher than that of a single negative pressure). This structure further solves the problem of feeding delay of high-viscosity syrup and high-viscosity sugar solution containing particles.

[0016] 3. The present invention controls the syrup injection volume through mechanical stroke limit, with an error ≤ ±0.5% (the standard deviation of 50 mL filling volume is ±0.25). In addition, each independent filling component and the material pipe connected thereto form multiple sets of independent and non-interfering filling structures, further ensuring the filling accuracy. Secondly, the closed filling channel formed by their connection and cooperation can effectively prevent external pollution during the syrup filling process.

[0017] 4. The filling component of the present invention adopts a modular design, enabling the nozzle to be installed in a quick-release manner, realizing the independent disassembly and maintenance of a single component, and can quickly disassemble and replace the nozzle adaptable to different specifications according to different pouring requirements, saving time for cleaning or other maintenance requirements. The whole system has a simple and reliable structure, and has the advantages of high efficiency, hygiene, etc. while ensuring the filling accuracy, and is especially suitable for the quantitative packaging requirements of various liquid or semi-liquid candies.

Detailed implementation manners

[0026] Typical implementation manners reflecting the features and advantages of the present invention will be specifically described in the following description. It should be understood that the present invention can have various changes in different implementation manners, all of which do not depart from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

[0027] In the description of the present application, the orientation or positional relationship indicated by terms such as "upper" and "lower" is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the structure referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0028] Please refer to Figures 1 to 4, the present invention provides a technical solution: a candy quantitative packaging device, including a storage tank 1 with syrup stored inside. A plurality of material pipes 2 are connected to the bottom of the storage tank 1. The tops of the plurality of material pipes 2 are all at the same horizontal height, and the upper ends of the material pipes 2 are perpendicular to the storage tank 1. The other ends of the material pipes 2 are commonly connected to an outer frame 3. One of the side parts 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. The included angle between the material pipes 2 and the side part of the outer frame 3 is between ten and thirty degrees, which is beneficial for the syrup inside the storage tank 1 to flow out through the material pipes 2.

[0029] Please refer to Figures 1 to 3 , along the length direction of the outer frame 3, a plurality of filling assemblies 4 are arranged in the outer frame 3. Each filling assembly 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 open the valve core and sprays out, and the spring 24 resets and seals at low pressure. The filling head 42 is fixedly connected to the outer frame 3 by screws.

[0030] There are several positioning protrusions 14 on the bottom inner wall of the outer frame 3 for positioning and installing the filling head 42. When the filling head 42 is inserted between the two positioning protrusions 14, the filling head 42 is directly opposite to the lower end outlet of the material pipe 2, so that the filling head 42 is inserted and communicated with the material pipe 2. Avoidance openings 13 are provided at the bottom of the outer frame 3. The width of the avoidance opening 13 is greater than the diameter of the nozzle 41, which is beneficial for the nozzle 41 to be installed following the filling head 42.

[0031] Please refer to Figure 2 , an operation space 15 is formed at intervals between two adjacent filling heads 42. Finger grooves 16 are respectively provided on both sides of the filling head 42. The two filling heads 42 are arranged at intervals to provide an operation space for the installation or disassembly of the filling head 42. Through the finger grooves 16, it is convenient to pull out, disassemble or install the filling head 42 when the filling head 42 is released from fixation, so that the nozzle 41 is of a detachable design and can be detached separately for replacement or maintenance. In addition, a common sealing structure (not shown) in the prior art can be provided at the connection between the filling head 42 and the material pipe 2. For example, an annular groove is machined on the end face of the lower end of the filling head 42 or the material pipe 2 and an "O" - ring (the material can be selected from nitrile rubber, fluororubber, etc.) is embedded to ensure the sealing performance between the filling head 42 and the material pipe 2.

[0032] Please refer to Figure 6, a limiting hole A23 is formed in the inner wall of the bottom of the outer frame 3. A spring 24 is fixedly arranged on the bottom wall of the limiting hole A23. The upper end of the spring 24 is fixedly provided with a limiting block 25. A limiting hole B26 which is inserted and matched with the limiting block 25 is formed in the bottom wall of the filling head 42. When the filling head 42 is inserted into the space between the two positioning protrusions 14, the filling head 42 presses the limiting block 25. Subsequently, when the filling head 42 moves to align the limiting block 25 with the limiting hole B26, the limiting block 25 extends into the limiting hole B26 under the action of the force generated by the spring 24 deforming back to its original state, thereby restricting the movement of the filling head 42. At this time, the filling head 42 reaches the installation position. Finally, the filling head 42 and the top of the outer frame 3 are fixed by screws. After the fixing of the filling head 42 by the screws is released, the filling head 42 can press the limiting block 25 downward again under the action of an external force, and the filling head 42 can be disassembled.

[0033] Please refer to Figure 2 and Figure 3 , a fixing head 44 is fixedly connected to the top of the filling head 42. A sleeve 45 is fixedly arranged on one side of the fixing head 44 away from the filling head 42. A through groove 19 is formed in the top of the outer frame 3 in a vertically penetrating manner. A positioning hole 18 which is vertically communicated with the material preparation cavity 43 is formed in the top of the filling head 42; The fixing head 44 includes a positioning head 20, a positioning plate 21 and a fixing plate 22 which are integrally formed. The positioning head 20 and the positioning plate 21 are respectively inserted and matched with the positioning hole 18 and the through groove 19. The fixing plate 22 is fixedly welded to the sleeve 45. The fixing head 44 passes through the through groove 19 and is inserted and matched with the filling head 42. In this way, not only can the filling head 42 be positioned and installed, but also the filling head 42 and the fixing head 44 are modularly arranged, and any one of the filling components 4 can be disassembled and maintained separately, especially when the syrup blocks the nozzle 41 or different specifications of the nozzle 41 need to be replaced for operation.

[0034] Please refer to Figures 1 to 3, a stock preparation cavity 43 communicating with the nozzle 41, the material pipe 2 and the sleeve 45 is formed inside the filling head 42. A piston rod A46 is slidably and sealingly assembled inside the sleeve 45. The upper ends of the plurality of piston rods A46 extend out of the sleeve and are commonly connected to a support plate 47. A power source 48 for driving the support plate 47 to move up and down is connected to the support plate 47. The power source 48 adopts a cylinder, or other structures in the prior art that can achieve the same purpose can also be used. When the power source 48 works, the support plate 47 rises or falls under the action of the power source 48. At this time, the plurality of piston rods A46 move along with the support plate 47. When the piston rod A46 moves downward, the syrup entering the stock preparation cavity 43 can be extruded out through the nozzle 41 for filling and packaging. When the piston rod A46 moves upward, the syrup in the material pipe 2 flows in and replenishes the stock preparation cavity 43 again. And during the upward movement of the piston rod A46, suction can be generated by suction, further accelerating the speed of the syrup flowing into the stock preparation cavity 43.

[0035] Please refer to Figure 1 , the output end of the power source 48 is fixedly connected with a connecting plate 5. 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 support plate 47. Such a design can drive the support plate 47 to rise or fall through the cooperation of the connecting plate 5 and the sliding rod 6 when the output end of the power source 48 moves.

[0036] Please refer to Figure 1 , the power source 48 is installed on a top plate 10. The sliding rod 6 is vertically slidably connected to the top plate 10. The bottom of the top plate 10 is fixedly connected with a vertical rod 11. The lower end of the vertical rod 11 is fixedly connected with a bottom plate 12, thereby installing the power source 48 and the sliding rod 6 and other structures.

[0037] Secondly, the bottom plate 12 is provided with the same avoidance opening 13 as that on the outer frame 3, which is convenient for the installation of the nozzle 41.

[0038] Please refer to Figure 5, an ear 7 is fixedly arranged outside the sliding rod 6, the other end of the ear 7 is fixedly provided with a piston rod B8, the central line of the piston rod B8 is parallel to the central line of the sliding rod 6, an air cylinder 9 is fixedly arranged outside the storage tank 1, the piston rod B8 is slidably and sealingly assembled in the air cylinder 9, the output end of the air cylinder 9 is communicated with the inside of the storage tank 1, a one-way valve (not shown) is installed at the output end of the air cylinder 9. When the power source 48 drives the sliding rod 6 to move downward to push the piston rod A46 to move downward for filling, the piston rod B8 slides downward to draw the external gas into the air cylinder 9. During the reset process of the sliding rod 6, the piston rod A46 not only draws the syrup into the preparation chamber 43, and at this time the piston rod B8 resets to fill the gas in the air cylinder 9 into the storage tank 1, and the syrup in the storage tank 1 is introduced into the material pipe 2.

[0039] In addition, a gas purifier and a one-way valve structure (not shown) are installed at the input end (air inlet end) of the air cylinder 9 to control the unidirectional flow of gas, and the gas is filled into the storage tank 1 after purification, so as to reduce the risk of syrup discharge pollution.

[0040] Please refer to Figure 1 , a feeding pipe 34 and an exhaust pipe 35 are arranged on the storage tank 1, which are respectively used for adding syrup into the storage tank 1, and the exhaust pipe 35 is used for exhausting the air inside the storage tank 1 before adding syrup. An electromagnetic valve is installed on the exhaust pipe 35 for opening or closing the exhaust pipe 35, and a sensor is installed on the storage tank 1, which monitors the liquid level in the storage tank 1 by ultrasonic wave to facilitate timely feeding. The specific control method and structure have been relatively maturely applied in the prior art and will not be elaborated here too much.

[0041] The inner wall of the material pipe 2 is spiral, and its spiral angle is between 15 and 25 degrees (if the angle is too small, the separation force is insufficient; if it is too large, the pressure loss increases), and the inlet pitch is greater than the outlet pitch. The spiral variable pitch design can avoid sudden change of flow velocity and prevent new bubbles from being generated by shear.

[0042] The spiral pipeline structure forces the syrup to move in a spiral motion, reduces gas entrainment, has a low bubble density of the sucked bubbles, and gathers towards the spiral center under the action of centrifugal force, reducing the outflow of gas and syrup together during filling, ensuring the filling accuracy, and is especially suitable for high-viscosity or bubble-sensitive syrups (such as aerated candies, transparent hard syrups).

[0043] Please refer to Figure 4 , a valve A32 is installed at the connection between the material pipe 2 and the storage tank 1 to prevent syrup backflow, and a valve B33 is installed at one end of the material pipe 2 connected to the outer frame 3. The valve B33 is used for opening or closing the material pipe 2 and can be used during maintenance.

[0044] Working principle of the present invention: When the syrup is filled and packaged, the power source 48 acts to drive the slide bar 6 to slide downward. On the one hand, when the slide bar 6 slides downward, it drives the pallet 47 to move. When the pallet 47 moves downward, it drives a plurality of the piston rods A 46 to move downward together to perform an injection action, and pour the syrup in the stock preparation chamber 43 downward through the nozzle 41 for filling. On the other hand, when the slide bar 6 slides downward, it drives the piston rod B 8 to move downward through the lug 7, and sucks the external gas into the inflation cylinder 9. After one filling is completed, the slide bar 6 moves upward and resets under the action of the power source 48. When the slide bar 6 moves upward and resets, on the one hand, when the piston rod A 46 resets upward, it sucks to generate negative pressure in the stock preparation chamber 43, and the syrup in the material pipe 2 flows into the stock preparation chamber 43 under the action of gravity and suction. On the other hand (at the same time), the piston rod B 8 resets and injects the gas entering the inflation cylinder 9 into the storage tank 1. At this time, the valve A 32 opens, and the syrup in the storage tank 1 is replenished and injected back into the material pipe 2. By setting the moving stroke of the slide bar 6 driven by the power source 48, the volume of the syrup entering the stock preparation chamber 43 can be controlled, so as to realize the quantitative packaging of candies (liquid or semi-liquid).

[0045] Please refer to Figure 7 , a production system, including the candy quantitative packaging device as described above. The bottom of the bottom plate 12 is fixedly connected with a mounting plate 27. The storage tank 1 is installed on a mounting frame 28. The mounting plate 27 and the mounting frame 28 are jointly connected to the conveying frame 29, so that the candy quantitative packaging device is installed on the packaging line. 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 left and right on the storage tank 1, and can cooperate with each other to simultaneously pour and fill a plurality of the molds 31 in two columns, improving the production efficiency. The specific conveying structure of the conveying frame 29 has been relatively maturely applied in the prior art and will not be elaborated here. After filling, it is conveyed to the next process through the conveyor belt for operations such as printing and packaging.

[0046] Finally, it should be noted that the above embodiments are only the 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 substitutions made by those skilled in the art on the basis of the present invention belong to the scope of protection required by the present invention.
