Description

Technical Field

[0001] This utility model belongs to the field of automatic filling technology, specifically relating to a multi-head filling structure for an automatic filling line. Background Technology

[0002] With the continuous improvement of industrial automation, automated filling technology has been widely used in various industries, especially in food, beverage, chemical and pharmaceutical industries, where the requirements for production efficiency and filling accuracy are increasing. Traditional manual or single-head filling systems can no longer meet the needs of modern production lines. Therefore, multi-head filling technology has emerged and become an important means to improve production efficiency, ensure product quality and reduce labor costs.

[0003] A prior art patent, CN212501327U, describes a high-efficiency automatic filling line. This patent includes filling equipment and a conveyor belt. The filling equipment has an internal conveyor belt that runs through it. A control frame is installed inside the filling equipment, and a filling mechanism is located at the bottom of the control frame. The filling mechanism consists of a telescopic rod, a filling machine, and an infrared sensor. The telescopic rod is located at the top of the filling machine, and the infrared sensor is located inside the filling machine. A clamping mechanism is located on the side of the filling mechanism. A control system is located inside the filling equipment… This device can efficiently complete the filling process through the control system, thus achieving efficient automatic filling. However, in practical use, it still has the following shortcomings: From a practical standpoint, the filling head is not easy to disassemble. Residue can easily accumulate on the filling head during long-term use. The difficulty in disassembling and cleaning the filling head makes cleaning difficult, potentially leading to cross-contamination of materials and affecting the quality of the finished product.

[0004] Therefore, there is a need for a multi-head filling structure for automatic filling lines to solve the problem of difficult cleaning caused by the inconvenience of disassembling filling heads in the existing technology. Utility Model Content

[0005] The purpose of this invention is to provide a multi-head filling structure for an automatic filling line to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-head filling structure for an automatic filling line, including a workbench, a plurality of support columns fixedly connected to the bottom of the workbench, a conveyor belt installed on the top of the workbench, a first convex frame fixedly connected to the middle position of the top of the workbench, a stirring mechanism provided on the top of the first convex frame, and a plurality of quick-release filling head mechanisms provided at the bottom of the first convex frame.

[0007] It should be noted in the solution that the outer wall of the conveyor belt is fixedly connected with multiple limiting grooves, and the inner wall of each limiting groove is fixedly connected with an anti-slip ring.

[0008] It is further worth noting that the stirring mechanism includes a storage box fixedly connected to the top of the first convex frame. The top of the storage box is fixedly connected to a feed inlet. Multiple rotating shafts are rotatably connected inside the storage box. Multiple sets of evenly distributed stirring blades are fixedly connected to the outer walls of the multiple rotating shafts. Synchronous pulleys are fixedly connected through the storage box to the top of the multiple rotating shafts. Synchronous belts are installed on the outer walls of the multiple synchronous pulleys. A second convex frame is fixedly connected to the top of the storage box. A servo motor is installed on the top of the second convex frame.

[0009] Furthermore, it should be noted that the output end of the servo motor passes through the top of the second convex frame and is fixedly connected to one of the synchronous pulleys.

[0010] In a preferred embodiment, the quick-release filling head mechanism includes a discharge trough that passes through the first convex frame and is fixedly connected to the bottom of the storage tank. A solenoid valve is installed at the front end of the discharge trough. Multiple connecting seats are fixedly connected to the bottom of the discharge trough. A disc is fixedly connected to the bottom of each of the multiple connecting seats. A sliding rod is fixedly connected to the bottom of each of the multiple discs. A first top is slidably connected to the outer wall of each of the multiple sliding rods. A second top is fixedly connected to the bottom of each of the multiple sliding rods. A connecting sleeve is detachably connected to the bottom of each of the multiple second tops. Through grooves are opened on both sides of the inner wall of each of the multiple connecting sleeves. Springs are fixedly connected to the inner wall of each of the multiple through grooves. Support rods are fixedly connected to the inner side of each of the multiple springs. A snap-fit ​​wedge is fixedly connected to the inner side of each of the multiple support rods. A mounting base is fixedly connected to the bottom of each of the multiple connecting sleeves. A filling nozzle corresponding to the discharge trough is fixedly connected inside the mounting base.

[0011] In a preferred embodiment, the disk is made of magnetic material, the first top is made of iron material, the first top and the second top have the same diameter and are symmetrically arranged in the horizontal direction.

[0012] In a preferred embodiment, the snap-fit ​​wedge slides on the inner wall of the through groove, the outer wall of the filling nozzle is in close contact with the inner wall of the discharge groove, and a sealing ring is fixedly connected to the inner wall of the discharge groove.

[0013] Compared with the prior art, the multi-head filling structure for an automatic filling line provided by this utility model has at least the following beneficial effects:

[0014] (1) By setting a quick-release filling head mechanism, when the connecting tube sleeve is pushed upward during installation, the two locking wedges retract inward due to the resistance of the second top head. When they pass through the second top head, the locking wedges are reset under the action of the spring. At this time, the mounting base is lowered, and the second top head and the locking wedges are locked and positioned. The filling nozzle is inserted into the inner wall of the discharge trough to complete the installation. When disassembly is required, the connecting tube sleeve is pushed upward again, and the locking wedges retract due to the squeezing resistance of the first top head. Then the connecting tube sleeve is pulled downward, and the locking wedges drive the first top head to slide downward. The first top head plays a guiding role while sliding downward, so that the locking wedges can directly pass through the second top head to complete the disassembly, replacing the traditional bolt installation. This makes the installation and disassembly of the filling nozzle simpler, improves the disassembly and assembly efficiency, and facilitates the cleaning of the inside of the filling nozzle.

[0015] (2) By setting up a stirring mechanism, the servo motor drives the synchronous wheel to rotate. Under the action of the synchronous belt, multiple sets of stirring blades can evenly stir the raw materials in the storage box, which can effectively prevent the raw material components from separating and ensure that the components are evenly distributed, thereby improving the overall quality of filling.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Please see Figure 1-5 This utility model provides a multi-head filling structure for an automatic filling line, including a workbench 1, a plurality of support columns 2 fixedly connected to the bottom of the workbench 1, a conveyor belt 3 installed on the top of the workbench 1, a first convex frame 4 fixedly connected to the middle position of the top of the workbench 1, a stirring mechanism 5 provided on the top of the first convex frame 4, and a plurality of quick-release filling head mechanisms 6 provided at the bottom of the first convex frame 4.

[0024] Further as Figure 1 and Figure 2 As shown, it is worth noting that the outer wall of the conveyor belt 3 is fixedly connected with multiple limiting grooves, and the inner wall of each limiting groove is fixedly connected with an anti-slip ring. The design of the limiting groove helps to accurately position the container and prevent the container from shifting or misaligning during the conveying process. The anti-slip ring further increases the friction between the limiting groove and the container, ensuring that each container can be filled stably.

[0025] Further as Figure 3 As shown, it is worth noting that the stirring mechanism 5 includes a storage box 501 fixedly connected to the top of the first convex frame 4. A feed inlet 502 is fixedly connected to the top of the storage box 501. Multiple rotating shafts 503 are rotatably connected inside the storage box 501. Multiple sets of evenly distributed stirring blades 504 are fixedly connected to the outer walls of the multiple rotating shafts 503. Synchronous pulleys 505 are fixedly connected to the top of the multiple rotating shafts 503 through the storage box 501. Synchronous belts 506 are installed on the outer walls of the multiple synchronous pulleys 505. A second convex frame 507 is fixedly connected to the top of the storage box 501. A servo motor 508 is installed on the top of the second convex frame 507. By setting the stirring mechanism 5, the multiple sets of stirring blades 504 can evenly stir the raw materials in the storage box 501, which can effectively prevent the raw material components from separating and ensure that the components are evenly distributed, thereby improving the overall filling quality.

[0026] Further as Figure 3 As shown, it is worth noting that the output end of the servo motor 508 passes through the top of the second convex frame 507 and is fixedly connected to one of the synchronous pulleys 505, ensuring that the servo motor 508 can drive the synchronous pulley 505 to rotate stably. Under the action of the synchronous belt 506, it can provide driving force for the rotation of the stirring blade 504.

[0027] As can be seen from the above working process, by setting up the stirring mechanism 5, multiple sets of stirring blades 504 can uniformly stir the raw materials in the storage box 501, which can effectively prevent the raw material components from separating and ensure that the components are evenly distributed, thereby improving the overall filling quality.

[0028] Further as Figure 4 and Figure 5As shown, it is worth noting that the quick-release filling head mechanism 6 includes a discharge trough 601 that passes through the first convex frame 4 and is fixedly connected to the bottom of the storage box 501. A solenoid valve 602 is installed at the front end of the discharge trough 601. Multiple connecting seats 603 are fixedly connected to the bottom of the discharge trough 601. A disc 604 is fixedly connected to the bottom of each of the multiple connecting seats 603. A sliding rod 605 is fixedly connected to the bottom of each of the multiple discs 604. A first top head 606 is slidably connected to the outer wall of each of the multiple sliding rods 605. A second top head 607 is fixedly connected to the bottom of each of the multiple sliding rods 605. A connecting sleeve 608 is detachably connected to the bottom of each of the multiple second top heads 607. Both sides of the inner wall of the connecting sleeve 608 are provided with through grooves 609. Springs 610 are fixedly connected to the inner wall of multiple through grooves 609. Support rods 611 are fixedly connected to the inner side of multiple springs 610. Snap wedges 612 are fixedly connected to the inner side of multiple support rods 611. Mounting bases 613 are fixedly connected to the bottom of multiple connecting sleeves 608. Filling nozzles 614 corresponding to the discharge trough 601 are fixedly connected inside the mounting bases 613. By setting up a quick-release filling head mechanism 6, the traditional bolt installation is replaced, making the installation and disassembly of the filling nozzles 614 simpler, improving the efficiency of disassembly and assembly, and facilitating the cleaning of the inside of the filling nozzles 614.

[0029] Further as Figure 4 and Figure 5 As shown, it is worth noting that the disc 604 is made of magnetic material, and the first head 606 is made of iron material, ensuring that the disc 604 can attract the first head 606, so that under normal conditions, the top of the first head 606 is in contact with the bottom of the disc 604; the first head 606 and the second head 607 have the same diameter and are symmetrically arranged in the horizontal direction, ensuring that during disassembly, the first head 606 slides downwards while acting as a guide, enabling the locking wedge 612 to directly pass through the second head 607 to complete the disassembly.

[0030] Further as Figure 4 and Figure 5 As shown, it is worth noting that the snap-fit ​​wedge 612 slides on the inner wall of the through groove 609, ensuring that the snap-fit ​​wedge 612 and the spring 610 are matched and can flexibly retract and reset on the inner wall of the through groove 609; the outer wall of the filling nozzle 614 is tightly fitted with the inner wall of the discharge trough 601, and a sealing ring is fixedly connected to the inner wall of the discharge trough 601. The sealing ring can effectively prevent the raw material from leaking from the discharge trough 601 during the filling process, ensuring the flow stability of the raw material during filling and avoiding leakage of the raw material.

[0031] This solution has the following working process: In actual use, the container to be filled is placed on top of the limiting groove, the conveyor belt 3 is turned on to drive multiple containers to move. When the container moves to the designated position, the conveyor belt 3 stops, multiple solenoid valves 602 open simultaneously, and multiple filling nozzles 614 fill the raw material in the storage tank 501 into the container. At the same time, the servo motor 508 is turned on to drive the synchronous wheel 505 to rotate. Under the action of the synchronous belt 506, multiple sets of stirring blades 504 uniformly stir the raw material in the storage tank 501. When it is necessary to disassemble or assemble the filling nozzle 614, during installation, the connecting sleeve 608 is pushed upward, and the two locking wedges 612 are subjected to the second top head 607. The resistance causes the wedge to contract inward. When it passes through the second top head 607, the spring 610 causes the locking wedge 612 to reset. At this time, the mounting base 613 is lowered, and the second top head 607 and the locking wedge 612 are locked and positioned. The filling nozzle 614 is inserted into the inner wall of the discharge trough 601 to complete the installation. When disassembly is required, the connecting sleeve 608 is pushed upward. The locking wedge 612 is compressed by the squeezing resistance of the first top head 606. Then the connecting sleeve 608 is pulled downward. The locking wedge 612 causes the first top head 606 to slide downward. The first top head 606 guides the locking wedge 612 to pass directly through the second top head 607 to complete the disassembly.

[0032] In summary: By setting up the stirring mechanism 5, multiple sets of stirring blades 504 can uniformly stir the raw materials in the storage tank 501, which can effectively prevent the raw material components from separating and ensure that the components are evenly distributed, thereby improving the overall filling quality; by setting up the quick-release filling head mechanism 6, the traditional bolt installation is replaced, making the installation and disassembly of the filling nozzle 614 simpler, improving the disassembly and assembly efficiency, and facilitating the cleaning of the inside of the filling nozzle 614.
