Description

Technical Field

[0001] This utility model relates to the field of food packaging machinery technology, and further to a multi-position synchronous filling device and filling production line system. Background Technology

[0002] In the food processing industry, filling technology is a common step in the production process. Filling machines can achieve higher production efficiency than manual labor. However, the traditional filling equipment commonly used in the industry can usually only perform filling or injection of a single material. With the rapid growth in market demand, the single-material filling mode can no longer meet the needs of efficient and intensive production. Existing technologies have revealed the following significant drawbacks in practical applications: When filling or injecting two or more materials simultaneously, manufacturers need to use multiple machines in series to complete the process. Each machine requires an independent operator, leading to a significant increase in labor costs. The combined purchase cost, maintenance cost, and energy consumption of multiple machines significantly increase the investment pressure on enterprises. Furthermore, the floor space occupied by the equipment increases linearly with the number of machines. In urban areas where industrial land is scarce, the proportion of factory space costs is particularly prominent, further weakening the profitability of enterprises. Moreover, multi-machine collaborative operation is prone to errors in process connection, reducing overall production efficiency, and exhibiting problems of equipment redundancy, high costs, and inefficient operation.

[0003] Therefore, there is an urgent need to develop an integrated device with multi-channel independent control capabilities that can simultaneously complete the filling and injection of various materials, in order to solve the technical problems of high cost, low efficiency and insufficient space utilization in the existing technology. Utility Model Content

[0004] In view of the above-mentioned technical problems, the purpose of this utility model is to provide a multi-position synchronous filling device, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a multi-position synchronous filling device, comprising:

[0006] A substrate, wherein a fixed station and a power station are provided on the substrate;

[0007] A valve body is fixedly installed on the fixed work position. The valve body has a rotating through hole and a plurality of filling through holes. The rotating through hole is opened along the axial direction of the valve body and is through. The plurality of filling through holes are arranged along the length direction of the valve body on the tube wall of the valve body and are correspondingly connected to the rotating through hole.

[0008] The valve core is rotatably disposed in the rotating through hole and adapted to the rotating through hole. The valve core has multiple three-way channels, which are connected to the filling through hole group.

[0009] A driving component is connected to the valve core to drive the valve core to rotate within the rotating through hole;

[0010] A piston power unit is disposed on the power station and is connected to the filling through hole group.

[0011] A hopper component is disposed on the valve body on the side away from the base plate. The hopper component is divided into multiple independent hoppers, and the hoppers are connected to the filling through hole group.

[0012] The nozzle component is disposed on the side of the valve body away from the hopper component and is connected to the filling through hole group. The nozzle component is disposed through the substrate.

[0013] By setting up multiple filling through-hole groups, the function of filling or injecting multiple groups of materials at the same time is realized, which greatly reduces the equipment purchase cost and labor cost. It has the advantages of simple operation and high efficiency, and can also meet the user's needs for simultaneous filling of diverse fillings, thus having better practicality.

[0014] In some embodiments, the filling through-hole assembly includes a discharge hole, a feed hole, and a rear frustum hole. The discharge hole is located on the side of the valve body away from the piston power assembly and is connected to the nozzle component. The feed hole is located on the side of the valve body away from the substrate and is connected to the hopper component. The rear frustum hole is located on the side of the valve body close to the piston power assembly and is connected to the piston power assembly. Both the rear frustum hole and the discharge hole are perpendicular to the feed hole.

[0015] By placing the feed port between the rear frustum and the discharge port, the material enters the piston power unit through the rear frustum via the shortest path from the feed port. The rear frustum and the discharge port are branched perpendicular to the feed port, forming a "T-shaped" three-way structure. This avoids turbulence or pressure loss caused by right-angle bends when the material is discharged, reduces flow resistance, and improves the adjustment response speed and discharge speed of the piston power unit.

[0016] In some embodiments, the valve body is provided with fixing parts at both ends corresponding to the rotating through hole, and each fixing part is provided with a sliding groove;

[0017] Two sets of parallel fixing plates are provided on the base plate, and the fixing plates slide into the corresponding grooves to fix the valve body on the base plate.

[0018] By using the sliding fit between the fixing plate and the slide groove to form a "plug-in" assembly structure, the valve body can be quickly aligned with the base plate by simply pushing it in along the slide groove during installation. This eliminates the tedious adjustment steps of traditional bolt fixing, thereby improving assembly efficiency and facilitating subsequent maintenance.

[0019] In some embodiments, a drive slot is provided on the side of the valve core near the drive component, and a handle is provided on the side of the valve core away from the drive component. A sealing element is provided between the drive slot and the three-way channel, and between the handle and the three-way channel.

[0020] By setting independent seals between the drive slot and the three-way channel, and between the handle and the three-way channel, a double isolation barrier is formed, further improving the sealing effect. The handle allows the valve core to be manually rotated in case of automatic drive failure, and the connection angle between the three-way channel and the nozzle component can be quickly reset by aligning the scale, reducing downtime for debugging, or facilitating the removal of the valve core during disassembly and assembly, thereby significantly improving the reliability, maintenance convenience and operational safety of the valve core assembly.

[0021] In some embodiments, the driving component includes a driving cylinder and a locking pin connecting shaft. The driving cylinder is connected to the locking pin connecting shaft via a bearing. The locking pin connecting shaft is correspondingly engaged in the driving slot so that the valve core rotates under the drive of the driving cylinder.

[0022] By adopting a plug-in docking structure that connects the pin-connecting shaft and the drive slot, the drive component can be axially separated from the valve body without disassembling the motor fixing bolts. This makes it easier to replace the drive unit, facilitates the assembly of the device, and significantly improves the reliability, environmental adaptability, and maintenance convenience of the drive system.

[0023] In some embodiments, the feed nozzle component includes a pressure plate and a plurality of feed nozzle hoppers, the openings of the feed nozzle hoppers are all connected to the discharge holes, and a discharge pipe is connected to the side of the feed nozzle hopper away from the discharge holes. The pressure plate has an extension hole corresponding to the discharge pipe. The pressure plate is fixed to the valve body by a first clamping bolt and is correspondingly disposed on the side of the feed nozzle hopper away from the valve body.

[0024] By threading the material through the pre-drilled hole in the pressure plate, the pressure plate is pressed against the end of the valve body, ensuring tight contact between the material nozzle and the valve body. This prevents filling leakage, enhances sealing, and also enables quick disassembly.

[0025] In some embodiments, a mating groove is provided on the side of the valve body near the feed hole, and the feed hole is disposed in the mating groove;

[0026] The hopper component includes a hopper body, and the hopper body has a docking interface corresponding to the docking groove on the side near the valve body.

[0027] By designing the docking groove and the interface, precise guidance is provided for the docking of the material barrel body and the valve body. The interlocking structure of the docking groove and the interface also forms the first seal, effectively preventing the filling from leaking out.

[0028] In some embodiments, the hopper component further includes two guide plates, which are respectively disposed on both sides of the docking groove along the length direction of the docking groove;

[0029] The guide plate has a clamping screw hole so that the material barrel body can be adjusted by the second clamping bolt.

[0030] In some embodiments, the piston power unit includes two piston pumps connected to the same servo motor, so that the servo motor drives the two piston pumps to move back and forth synchronously, thereby achieving quantitative driving of the two piston pumps.

[0031] According to another aspect of the present invention, the present invention further provides a filling production line system, comprising:

[0032] A conveying device for conveying pastries;

[0033] As described in any of the above embodiments, the multi-position synchronous filling device is disposed directly above the conveying device, and the nozzle component faces the conveying device.

[0052] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0053] In one embodiment, refer to the appendix to the specification. Figure 1-8The present invention provides a multi-position synchronous filling device, comprising a base plate 1, a valve body 3, a valve core 6, a drive component 2, a piston power unit, a nozzle component 4, and a hopper component 5. The base plate 1 is provided with a fixed station and a power station. The valve body 3 is fixedly mounted on the fixed station. The valve body 3 has a rotating through hole 32 and multiple filling through holes. The rotating through hole 32 is opened along the axial direction of the valve body 3 and is continuous. The multiple filling through holes are arranged along the length direction of the valve body 3 on the pipe wall of the valve body 3 and are correspondingly connected to the rotating through hole 32. The valve core 6 is rotatably mounted on the rotating through hole 32. The valve core 6 is adapted to the rotating through hole 32. Multiple three-way channels 62 are opened on the valve core 6. The three-way channels 62 are connected to the filling through hole group. The driving component 2 is connected to the valve core 6 to drive the valve core 6 to rotate in the rotating through hole 32. The piston power unit is set on the power station and is connected to the filling through hole group. The nozzle component 4 is set on the side of the valve body 3 away from the piston power unit and is connected to the filling through hole group. The hopper component 5 is set on the side of the valve body 3 away from the base plate 1. The hopper component 5 is divided into multiple independent hoppers. The hoppers are connected to the filling through hole group. The nozzle component is set through the base plate.

[0054] Specifically, the base plate 1 serves as the core support platform, with a fixed station and a power station. The fixed station is used to install the valve body 3, and the power station is used to fix the piston power assembly, enabling the entire device to be stably connected to the base plate 1, thereby achieving the function of stable filling. The valve body 3 is a hollow tubular structure, with a rotating through hole 32 extending axially along its length. Multiple filling through-hole groups are formed along the length of the tube wall of the valve body 3, each group containing several through holes. All through holes are located on the tube wall of the valve body 3. The valve core 6 is a cylindrical structure, with its outer wall fitting tightly against the inner wall of the rotating through hole 32. A handle is provided at the right end of the valve core 6 to facilitate insertion into the valve body 3 from right to left or extraction from the opposite direction. A slot is provided at the left end of the valve core 6 for... Connected to the drive component 2, the valve core 6 is ensured to rotate stably within the rotation through hole 32 of the valve body 3. The valve core 6 is driven by the drive component 2 to rotate back and forth by 90°, thereby realizing the switching action of material suction or discharge. In addition, multiple three-way channels 62 are opened circumferentially on the surface of the valve core 6. Each three-way channel 62 can be connected to the through hole of the filling through hole group, thereby realizing the rapid switching of material channels by rotating the valve core 6. In addition, the piston power unit is installed on the power station of the base plate 1. The connection end of the piston power unit is connected to the filling through hole group of the valve body 3 through a rigid pipe. The nozzle component 4 is fixed on the side of the valve body 3 away from the piston power unit. The outlet end of the nozzle component 4 can be replaced with nozzles of different diameters or shapes according to product requirements to adapt to irregular filling processes. The hopper component 5 is installed on the top of the valve body 3 and may include multiple independent hoppers. The end of the hopper near the base plate 1 is provided with a ramp to facilitate the material to slide down. Each hopper is independently connected to the corresponding filling through hole group, thereby realizing the independent operation of each material channel.

[0055] It should be noted that both ends of the valve core 6 are provided with sealing ring grooves and sealing rings. Every two three-way channels 62 form a group, and each group is provided with sealing ring grooves and sealing rings to separate different fillings. In addition, the piston power unit can be a high-precision gear pump, a plunger pump, or other pumps that adjust the flow and pressure of different materials through an independent controller. No limitation is made here.

[0056] In one embodiment, refer to the appendix to the specification. Figure 1 and 2 Based on the above embodiments, the filling through-hole group includes a discharge hole 33, a feed hole 31, and a rear frustum hole. The discharge hole 33 is opened on the side of the valve body 3 away from the piston power unit and is correspondingly connected to the nozzle component 4. The feed hole 31 is opened on the side of the valve body 3 away from the base plate 1 and is correspondingly connected to the hopper component 5. The rear frustum hole is opened on the side of the valve body 3 close to the piston power unit and is correspondingly connected to the piston power unit. Both the rear frustum hole and the discharge hole 33 are arranged perpendicular to the feed hole 31.

[0057] Specifically, the three-way channel 62 includes a three-way upper hole 31, four sets of three-way rear holes 32, and four sets of three-way front holes 34. The three-way upper hole 31, four sets of three-way rear holes 32, and four sets of three-way front holes 34 respectively connect to the feed hole 31, the rear frustum hole, and the discharge hole 33. By setting the feed hole 31 between the rear frustum hole and the discharge hole 33, the material enters the piston power unit through the rear frustum hole via the shortest path from the feed hole 31. The rear frustum hole and the discharge hole 33 are branched perpendicular to the feed hole 31 to form a "T-shaped" three-way structure, which can avoid turbulence or pressure loss caused by right-angle bends when the material is discharged, reduce flow resistance, and improve the adjustment response speed and discharge speed of the piston power unit.

[0058] It should be noted that the feed hole 31 is a square hole on the top of the valve body, and the diameter of the rear frustum hole gradually increases outward. The intersection of the center lines of the feed hole 31, the discharge hole 33 and the rear frustum hole coincides with the center line of the rotating through hole. A sealing ring groove is provided around the feed hole 31 for installing the sealing ring to achieve mutual sealing with the hopper components.

[0059] In one embodiment, refer to the appendix to the specification. Figure 1 , 2 In addition to the above embodiments, the valve body 3 is provided with a fixing part 34 at both ends corresponding to the rotating through hole 32, and a sliding groove 35 is provided on the fixing part 34. Two sets of parallel fixing plates 11 are provided on the base plate 1. The fixing plates 11 slide into the sliding groove 35 to realize the valve body 3 being fixedly installed on the base plate 1.

[0060] Specifically, the surfaces of the valve body 3 corresponding to the nozzle component 4 and the piston power unit 7 are inclined downward to form a fixing part 34. The side profile of the valve body 3 viewed from the extension direction of the valve core 6 presents a figure-eight shape. The fixing part 34 is fixed with two sliding plates to form a sliding groove 35 that matches the fixing plate 11. After the fixing plate 11 slides into the sliding groove 35, the fixing plate 11 is fixed in the sliding groove 35 by the clip 12 and the locking bolt 13. The opening direction of the sliding groove 35 on the fixing part 34 is perpendicular to the length direction of the valve body 3. The sliding fit between the fixing plate 11 and the sliding groove 35 forms a "plug-in" assembly structure. During installation, the valve body 3 only needs to be pushed in along the direction of the sliding groove 35 to complete the quick alignment with the base plate 1, eliminating the cumbersome adjustment steps of traditional bolt fixing, thereby improving the assembly efficiency and facilitating subsequent maintenance.

[0061] In one embodiment, refer to the appendix to the specification. Figure 1 and 3 A drive slot 61 is provided on the side of the valve core 6 near the drive component 2, and a handle 64 is provided on the side of the valve core 6 away from the drive component 2. A sealing element 63 is provided between the drive slot 61 and the three-way channel 62, and between the handle 64 and the three-way channel 62.

[0062] Specifically, by setting independent sealing elements 63 between the drive slot 61 and the three-way channel 62, and between the handle 64 and the three-way channel 62, a double isolation barrier is formed, further improving the sealing effect. The handle 64 allows the valve core 6 to be manually rotated in case of automatic drive failure, and the connection angle between the three-way channel 62 and the nozzle component 4 can be quickly reset by aligning the scale, reducing downtime for debugging, or facilitating the removal of the valve core 6 during disassembly and assembly. This significantly improves the reliability, ease of maintenance, and operational safety of the valve core 6 assembly, making it particularly suitable for applications with high hygiene requirements, such as food filling, or applications with high-frequency switching of multiple material ratios, such as chemical processing.

[0063] In one embodiment, refer to the appendix to the specification. Figure 1 , 5 In addition to the above embodiments, the driving component 2 includes a driving cylinder and a locking pin connecting shaft. The driving cylinder is connected to the locking pin connecting shaft through a bearing. The locking pin connecting shaft is correspondingly locked in the driving slot 61 so that the valve core 6 rotates under the drive of the driving cylinder.

[0064] Specifically, the drive assembly also includes a drive cylinder 29, a bearing 21, a bearing clip 22, a bearing seat 23, a clip rod, and a clip post output shaft 24. The drive cylinder is connected to the clip post connecting shaft 24 via the clip rod. The bearing 21 is mounted on the valve body 3 via the bearing seat 23. The drive cylinder drives the valve core 3 to rotate 90° forward and backward, thereby forming two working positions for the rotary valve: material suction and material discharge. The clip post connecting shaft 24 and the drive slot 61 are connected by a plug-in docking structure, so that the drive component 2 can be axially separated from the valve body 3 without disassembling the motor fixing bolts. This makes it easier to replace the drive unit, facilitates the assembly of the device, and significantly improves the reliability, environmental adaptability, and maintenance convenience of the drive system.

[0065] It should be noted that the instruction manual is attached. Figure 1 , 5 The drive assembly also includes a fisheye connector 27, a U-shaped crank arm 28, and a nut with a shaft. The drive cylinder is fixed to the base via a cylinder mounting seat 26. The piston rod 25 of the drive cylinder is threadedly connected to the fisheye connector. The other end of the fisheye connector 27 is connected to the corresponding pin of the U-shaped crank arm 28. Specifically, the two sides of the U-shaped crank arm 28 are respectively provided with pin holes that are compatible with the universal bushing 271 of the fisheye connector 27. The lower part of the U-shaped crank arm 28 is provided with a shaft hole 281 and a keyway that are compatible with the drive shaft, so as to achieve a corresponding connection with the drive shaft. In addition, the slot of the valve core 6 is L-shaped so that when the valve core 6 is rotated during cleaning, the locking rod and the slot of the valve core 6 are aligned with the extraction direction, thereby facilitating the extraction and disassembly of the valve core 6.

[0066] In one embodiment, refer to the appendix to the specification. Figure 1 and 6Based on the above embodiments, the nozzle component 4 includes a pressure plate 42 and a plurality of nozzle hoppers 41. The openings of the nozzle hoppers 41 are all connected to the discharge holes. The side of the nozzle hoppers 41 away from the discharge holes is connected to a discharge pipe 44. The pressure plate 42 has an extension hole corresponding to the discharge pipe 44. The pressure plate 42 is fixedly mounted on the valve body 3 by a first clamping bolt 43 and is correspondingly mounted on the side of the nozzle hoppers 41 away from the valve body 3.

[0067] Specifically, the opening of each feed nozzle 41 is designed to be conical or trumpet-shaped. The discharge pipe 44 is used for filling needles. The rear of the discharge pipe 44 is provided with a sealing ring groove and a sealing ring for use on the side of the feed nozzle 41 away from the discharge hole to provide a sealing effect. Each feed nozzle 41 forms a precise fit with the discharge hole 33 of the valve body 3 to ensure a smooth transition of the filling flow path and reduce resistance. In addition, the feed nozzle 41 is extended to the operating position through the discharge pipe 44 to ensure that the final discharge position and angle can be flexibly adjusted according to the arrangement of the dough mold, thereby ensuring that the filling is accurately injected into the center of the dough. The feed nozzle 41 is pressed against the end of the valve body 3 by passing through the preset hole of the pressure plate 42 through the threaded connection, ensuring that the feed nozzle 41 and the valve body 3 are in close contact, thereby preventing filling leakage and enhancing the sealing performance, and also achieving the effect of quick disassembly.

[0068] In one embodiment, refer to the appendix to the specification. Figure 1 and 7 Based on the above embodiments, the valve body 3 is provided with a docking groove on the side near the feed hole, and the feed hole is provided in the docking groove. The hopper component 5 includes a hopper body 51, and the hopper body 51 is provided with a docking interface corresponding to the docking groove on the side near the valve body 3.

[0069] Specifically, the groove of the docking slot is a concave structure that extends along the length of the valve body 3 and is directly connected to the feed hole. By setting the docking slot and the interface, a precise guide is provided for the docking of the material barrel body 51 and the valve body 3. The interlocking structure of the docking slot and the interface also forms the first seal, effectively preventing the filling from leaking out.

[0070] In one embodiment, refer to the appendix to the specification. Figure 1 and 7 Based on the above embodiments, the hopper component 5 also includes two guide plates 36. The two guide plates 36 are respectively arranged on both sides of the docking groove along the length direction of the docking groove. The guide plates 36 are provided with clamping screw holes so that the hopper body 51 can be adjusted by the second clamping bolt 37.

[0071] Specifically, the guide plate 36 can adopt a T-shaped cross-section design. The guide plate 36 can be fixed to the valve body 3 by screws passing through the fixing hole 52, so that the material barrel can be accurately positioned in the docking groove by sliding along the length direction of the guide plate 36, which further improves the installation accuracy. The second clamping bolt 37 can adopt a wing nut design, which can lock or release the material barrel by manual rotation, thereby shortening the disassembly time and achieving the effect of quick installation, making the installation and use of the entire device more convenient and practical.

[0072] It should be noted that a limiting plate is also provided on the side of the valve body 3 corresponding to the docking groove to further improve the connection and sealing between the material barrel and the valve body 3.

[0073] In one embodiment, refer to the appendix to the specification. Figure 1 , 7 8. The piston power unit 7 includes two piston pumps, which are connected to the same servo motor 76, so that the servo motor 76 drives the piston pumps to move back and forth synchronously, thereby realizing the quantitative drive of the two piston pumps.

[0074] Specifically, the piston pump includes a piston cylinder 71, a piston 72, a piston rod 73, a variable stage flange, a support base, and a nut. The piston cylinder has a circular opening 74 at its front end, and a sealing ring hole and a sealing ring on its outer wall, which are inserted into the rear frustum hole of the valve body 3 for sealing. The piston is driven by the piston rod to complete the suction and discharge work. The support base 75 is used to fix the piston pump on the base plate 1. The variable stage flange is fixed to the front of the support base with screws. The outer periphery of the variable stage flange is provided with multiple steps of different diameters to install piston cylinders of different diameters, thereby meeting the specification change requirements of different metering filling volumes. Every two piston rods are connected to the same nut, so that the nut can be driven back and forth by a servo motor 76 to quantitatively drive the two piston power units 7.

[0075] The specific working principle of this utility model is as follows: When the valve core 6 rotates to the corresponding suction position, the upper hole of the three-way channel 62 of the valve core 6 is connected to the feed hole 31 of the valve body 3, the rear hole of the three-way of the valve core 6 is connected to the rear frustum hole of the valve body 3, and the lower hole of the three-way of the valve core 6 is blocked by the inner wall of the valve body 3, so that the filling can enter the piston power unit in a preset amount. When the valve core 6 rotates to a driving angle of 90°, when the valve core 6 is in the discharge position, the rear hole of the three-way of the valve core 6 rotates to the bottom of the valve body 3 and is blocked by the inner wall of the valve body 3. The upper hole of the three-way of the valve core 6 and the lower hole of the valve core 6 become horizontal and are connected to the front and rear holes of the valve body 3, so that the piston power unit is connected to the hopper, and the quantitative filling is discharged from the hopper.

[0076] According to another aspect of the present invention, the present invention further provides a filling production line system, comprising:
