Description

Technical Field

[0001] This utility model relates to the field of filling device technology, specifically to a flat-push mother-daughter tube chain machine. Background Technology

[0002] Pipe filling generally involves multiple processes, such as filling, sealing, and waste removal. Commonly, filling and sealing processes are often located together, while other processes, such as waste removal, are located in different workshops. Manual material transfer is required between these processes, resulting in low efficiency, which needs to be improved. Utility Model Content

[0003] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:

[0004] This application discloses a flat-push chain conveyor, including a base, on which a feeding component, a conveying component, a filling component, an ultrasonic sealing component, and a cutting component are arranged. The feeding component is used to feed materials to the conveying component. The conveying component passes through the filling component, the ultrasonic sealing component, the cutting component, and the discharging component. The filling component performs a filling action on the workpiece conveyed by the conveying component, the ultrasonic sealing component performs a sealing action on the filled workpiece conveyed by the conveying component, and the cutting component performs a cutting action on the sealed workpiece conveyed by the conveying component to cut off the excess part.

[0005] This device features a rationally arranged feeding assembly, conveying assembly, filling assembly, ultrasonic sealing assembly, and cutting assembly. The feeding assembly feeds the workpiece (such as a tube) to the corresponding functional mechanism via the conveying assembly, thereby completing the filling, ultrasonic sealing, and removal of excess parts in sequence. This improves the automation level and efficiency of the filling process.

[0006] Furthermore, the feeding assembly includes a hopper and a pushing mechanism. The pushing mechanism is located at the outlet of the hopper and includes a telescopic mechanism and a push plate. A pushing groove for placing workpieces is provided at the outlet, which receives the workpieces discharged from the outlet. The corresponding part of the conveying assembly is located below the opening of the pushing groove. The telescopic mechanism drives the push plate to move along the pushing groove, and the push plate pushes the workpiece in the pushing groove to fall from the opening of the pushing groove into the conveying assembly below. In this solution, the hopper pre-stores the tube body, and the tube body moves from the outlet to the pushing groove to complete the initial positioning. Then, the telescopic mechanism moves the push plate to push the tube body out of the pushing groove and onto the conveying assembly below.

[0007] Furthermore, the hopper includes a hopper body, a sliding plate, a pressure plate, and a mounting seat. The sliding plate is inclined downward at the discharge port, and the mounting seat is provided at the end of the sliding plate. The pressure plate is provided above the sliding plate, and a chute is formed between the pressure plate and the sliding plate for the workpiece to slide down. A push tube groove is provided on the mounting seat. The telescopic mechanism is connected to the mounting seat. The tube in the hopper body slides out from the discharge port onto the sliding plate and slides down the sliding plate to the push tube groove.

[0008] Furthermore, a connecting plate is provided on the chamber body, and the pressure plate is connected to the connecting plate by threaded fasteners. The distance between the pressure plate and the sliding plate can be adjusted by the threaded fasteners. The position of the pressure plate can be adjusted according to different tube models without affecting the sliding and downward movement of the tube body.

[0009] Furthermore, the ultrasonic sealing assembly includes a lifting mechanism 1, a mounting base 1, a telescopic mechanism 2, a telescopic mechanism 3, an ultrasonic mechanism, and a sealing mold. The mounting base 1 is provided at the moving end of the lifting mechanism 1 to adjust its position longitudinally. The telescopic mechanism 2 and the telescopic mechanism 3 are provided on the mounting base 1. The moving end of the telescopic mechanism 2 is connected to the left mold in the sealing mold. The telescopic mechanism 3 is connected to the ultrasonic mechanism, and the transducer in the ultrasonic mechanism is connected to the right mold in the sealing mold. The telescopic mechanism 2 and the telescopic mechanism 3 move the left and right molds in opposite directions to seal the workpiece conveyed by the conveying assembly. In use, if the position of the sealing mold is pre-adjusted by the lifting mechanism 1 according to the height of the tube, when the conveying assembly moves the tube between the left and right molds, the telescopic mechanism 2 and the telescopic mechanism 3 merge the left and right molds to complete the sealing of the tube.

[0010] Furthermore, an adjustment plate is provided at the moving end of the telescopic mechanism two. An adjustment groove is provided on the adjustment plate along the longitudinal direction, and the left mold is connected to the adjustment groove by fasteners. Loosening the fasteners can adjust the up and down position of the left mold and improve its adaptability to the pipe body.

[0011] Furthermore, the cutting assembly includes a second lifting mechanism, a second mounting base, a first cutting blade, a second cutting blade, and a fourth telescopic mechanism. The second mounting base is provided at the moving end of the second lifting mechanism to adjust its position longitudinally. The first cutting blade and the fourth telescopic mechanism are provided on the second mounting base. The second cutting blade is provided at the moving end of the fourth telescopic mechanism. The fourth telescopic mechanism moves the second cutting blade toward the first cutting blade to cut off the excess part on the workpiece transferred by the conveying assembly. In use, the position of the second mounting base can be adjusted in advance according to the height of the tube body through the second lifting mechanism, so that the cutting blade corresponds to the excess part on the tube body for easy cutting.

[0012] Furthermore, the conveying assembly includes a conveyor belt mechanism and a grooved cup holder. The conveyor belt mechanism has cup holders spaced along the length of the bag body. The groove of the cup holder is used for inserting the workpiece. The grooved cup holder facilitates the placement of the tube body and improves the stability of the transfer.

[0013] Furthermore, it also includes a pressing tube assembly, a aligning assembly, a discharging assembly, and a control terminal. The pressing tube assembly is located between the filling assembly and the feeding assembly. When the conveying assembly moves the workpiece to the pressing tube assembly, the pressing tube assembly presses the workpiece down to a predetermined position.

[0014] The benchmarking component is located between the filling component and the ultrasonic sealing component. When the conveying component transfers the workpiece to the benchmarking component, the benchmarking component positions the workpiece.

[0015] The discharge component is located behind the cutter component. When the conveying component transfers the workpiece to the discharge component, the discharge component removes the workpiece from the cup holder in the conveying component.

[0016] The feeding assembly, conveying assembly, filling assembly, ultrasonic sealing assembly, cutting assembly, tube pressing assembly, alignment assembly, and discharging assembly are all connected to the control terminal, which controls the execution of predetermined actions. The tube pressing assembly adjusts the tube to a predetermined height to facilitate subsequent filling and sealing processes. The alignment assembly determines the position of the tube to facilitate subsequent sealing operations. The discharging assembly removes the workpiece, further improving the level of automation.

[0017] Furthermore, the discharge assembly includes an upper lifting cylinder, a front pushing cylinder, and a discharge trough. The discharge trough, the front pushing cylinder, and the upper lifting cylinder are all mounted on the machine base, with the front pushing cylinder positioned above the cup holder and its moving end moving towards the discharge trough. The bottom of the cup holder has a through hole for the moving end of the upper lifting cylinder to enter and exit. When the conveying assembly moves the cup holder above the upper lifting cylinder, the moving end of the upper lifting cylinder extends through the through hole to push the workpiece out of the cup holder. The front pushing cylinder pushes the pushed-out tube to the discharge trough. The upper lifting cylinder pushes the tube out of the cup holder, and the front pushing cylinder pushes the tube to the discharge trough. This simplifies the structure and reduces costs.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] like Figure 1 , Figure 2 As shown, the flat-push tube chain machine in this example includes a base 1. The base 1 is equipped with a feeding assembly 2, a conveying assembly 3, a filling assembly 5, an ultrasonic sealing assembly 7, and a cutting assembly 8. For example, the feeding assembly 2 is installed on the right side of the base 1 to feed the tube to the conveying assembly 3. If the tube is moved to the conveying assembly, the filling assembly 5, the ultrasonic sealing assembly 7, and the cutting assembly 8 are installed in sequence along the extension direction of the conveying assembly 3. The conveying assembly 3 moves the tube to the filling assembly 5, the ultrasonic sealing assembly 7, and the cutting assembly 8. The tube conveyed by the filling assembly 5 to the conveying assembly 3 is filled. The ultrasonic sealing assembly 7 seals the filled workpiece conveyed by the conveying assembly 3. The cutting assembly 8 cuts off the excess part of the sealed workpiece conveyed by the conveying assembly 3, such as the part left above the sealing line.

[0031] For conveying components, such as the common conveyor belt type, there is a conveyor belt mechanism and a grooved cup holder 31. The cup holder 31 is fixed at intervals along the length direction on the bag body in the conveyor belt mechanism. The groove of the cup holder is used for inserting the tube workpiece. The feeding component moves the tube to the cup holder and then moves it to the corresponding functional mechanism.

[0032] In addition, such as Figure 1 , Figure 2 As shown, a pressing tube assembly 4, a aligning assembly 6, a discharging assembly 9, and a control terminal 10 can also be added. If the control terminal 10 is installed on the side of the base 1, the pressing tube assembly 4 is located between the filling assembly 5 and the feeding assembly 2. When the conveying assembly 3 moves the workpiece to the pressing tube assembly 4, the pressing tube assembly 4 presses the workpiece down to a predetermined position. For the pressing tube assembly, if it is a telescopic cylinder driven pressing block type, the telescopic cylinder is fixed above the conveying assembly. When the conveying assembly moves the tube body to below the pressing block, the telescopic cylinder moves the pressing block down to press the tube body down to a predetermined height.

[0033] The alignment component 6 is located between the filling component 5 and the ultrasonic sealing component 7. When the conveying component transfers the workpiece to the alignment component, the alignment component positions the workpiece. The alignment component is a common camera alignment and positioning type, which can be directly purchased from the market.

[0034] The discharge component 9 is located behind the cutter component 8. When the conveying component 3 transfers the workpiece to the discharge component 9, the discharge component 9 removes the workpiece from the cup seat in the conveying component 3. Common discharge components include robotic arms, which use robotic arms to clamp the tube body out. In this example, to reduce costs, the preferred structure of the discharge assembly is as follows: The discharge assembly 9 includes an upper lifting cylinder, a front pushing cylinder 92, and a discharge trough 91. The front pushing cylinder and the upper lifting cylinder can be common cylinders purchased from the market. The discharge trough 91, the front pushing cylinder 92, and the upper lifting cylinder are all installed on the machine base 1. If the discharge trough 91 is tilted downwards, the front pushing cylinder 92 is above the cup holder 31 and its moving end moves towards the discharge trough. The bottom of the cup holder is formed with a through hole for the moving end of the upper lifting cylinder to enter and exit. When the conveying assembly moves the cup holder above the upper lifting cylinder, the moving end of the upper lifting cylinder extends through the through hole to push the workpiece out of the cup holder. The front pushing cylinder pushes the pushed tube to the discharge trough. To improve the stability of the pushing and forward pushing, a top block can be fixed at the moving end of the upper lifting cylinder to increase the contact area with the tube, and a push block can be fixed at the moving end of the front pushing cylinder, also to increase the contact area with the tube.

[0035] The feeding assembly, conveying assembly, filling assembly, ultrasonic sealing assembly, cutting assembly, tube pressing assembly, alignment assembly, and discharge assembly are all connected to the control terminal, which controls the execution of predetermined actions.

[0036] For the feeding components, the necessary equipment, such as robotic arms, can be purchased from the market according to requirements, preferably such as... Figure 1 , Figure 5As shown, the feeding assembly 2 includes a hopper and a pusher mechanism. The pusher mechanism is installed at the outlet 21 of the hopper and includes a telescopic mechanism 26 and a pusher plate 27. The telescopic mechanism is like a common cylinder. A pusher groove 28 for inserting workpieces is installed at the outlet 21 to receive workpieces discharged from the outlet. To facilitate unloading, in this example, the hopper includes a hopper body 20, a slide plate 22, a pressure plate 23, and a mounting seat 25. The slide plate 22 is fixed downward at the outlet 21 at the bottom of the hopper body 20, and the mounting seat 25 is installed at the end of the slide plate. The pressure plate 23 is installed above the slide plate 22, and a chute is formed between the pressure plate and the slide plate for the tube workpiece to slide down. The pusher groove 28 is formed on the mounting seat 25 and is located at the end of the slide plate 22. The tubes pre-stored in the hopper body slide out from the outlet onto the slide plate, and the tubes sliding down the slide plate fall into the chute. The telescopic mechanism 26 is connected to the mounting base 25. If it is fixed below the push tube groove, the push plate 27 is located at the end of the push tube groove 28. The telescopic mechanism 26 moves the push plate 27 along the push tube groove 28, thereby pushing the tube body in the push tube groove forward. If the cup holder 31 on the conveyor belt in the conveying assembly 3 is located below the beginning of the push tube groove, the tube body will slide from the beginning groove into the cup holder cavity under the push of the push plate. The mounting base can be fixed with bolts or the like for easy position adjustment.

[0037] Connecting plates 24 can also be installed at intervals along the length of the slide plate 22 on the chamber body 20. The pressure plate and the connecting plate are connected by threaded fasteners (such as bolts and matching nuts). The distance between the pressure plate and the slide plate can be adjusted by turning the bolts and nuts to facilitate the sliding of tubes of different models.

[0038] The filling components 5 are directly sourced from commercially available interfaces, such as common pressure filling and gravity filling types. Multiple filling components can be distributed at intervals along the conveying components. In use, one filling component can be used to fill the tube that is being moved to the conveying components, and then another filling component can be used to continue filling the tube that is being moved to the conveying components.

[0039] For ultrasonic sealing components, they can also be purchased directly from the market, with the preferred choice being... Figure 3The configuration shown, such as the ultrasonic sealing assembly 7, includes a lifting mechanism 71, a mounting base 70, a telescopic mechanism 77, a telescopic mechanism 78, an ultrasonic mechanism 72, and a sealing mold. The mounting base 70 is placed at the moving end of the lifting mechanism 71 to adjust its position longitudinally. The lifting mechanism can be a common hydraulic cylinder type, an electric screw lifting type, or a manual screw lifting type as shown in this example. Mounting base 70 is frame-shaped. Telescopic mechanisms 77 and 78 are installed inside the frame opening. The moving end of telescopic mechanism 77 is connected to the left mold 74 in the sealing mold. Telescopic mechanism 78 is connected to the ultrasonic mechanism 72, and the transducer in the ultrasonic mechanism 72 is connected to the right mold 73 in the sealing mold. Telescopic mechanisms 77 and 78 move towards each other, merging the left and right molds to seal the tube conveyed by the conveying component. During use, if the position of the sealing mold is pre-adjusted according to the height of the tube using lifting mechanism 1, and the conveying component moves the tube between the left and right molds, telescopic mechanisms 77 and 78 merge the left and right molds to complete the sealing of the tube. Telescopic mechanisms 77 and 78 resemble common telescopic cylinders.

[0040] An adjustment plate 75 can also be installed at the moving end of the telescopic mechanism 77. An adjustment groove 76 is formed along the longitudinal direction on the adjustment plate 75, and the left mold is connected to the adjustment groove by fasteners (such as bolts and matching nuts). The bolt extends from the hole of the left mold to the adjustment groove and is fixed with a nut. Loosening the nut can move the position of the left mold up and down, and then it can be fixed with a nut.

[0041] For the cutting blade assembly, the corresponding functional components can also be purchased commercially. Preferably, ... Figure 4 The structure shown, such as the cutter assembly 8, includes a second lifting mechanism 81, a second mounting base 82, a first cutter 84, a second cutter 85, and a fourth telescopic mechanism 83. The second lifting mechanism can be a common hydraulic cylinder type, an electric screw lifting type, or a manual screw lifting type as shown in this example. The second mounting base 82 is placed at the moving end of the second lifting mechanism 81 to adjust its position longitudinally. The first cutter 84 and the fourth telescopic mechanism 83 are installed on the bottom surface of the second mounting base 82. The second cutter 85 is fixed at the moving end of the fourth telescopic mechanism 83. The fourth telescopic mechanism moves the second cutter towards the first cutter to combine and cut off the excess part on the conveying assembly transfer tube. In use, if the position of the second mounting base is adjusted in advance according to the height of the tube by the second lifting mechanism, the two cutters can be combined to cut off the excess part on the tube sealing line.

[0042] Mounting base 2 can be connected to the moving end of lifting mechanism 2 via bolts. The position of mounting base 2 can be finely adjusted by turning the bolts up and down. Cutter 1 can also be connected to mounting base 2 via bolts, etc., so that the up and down position of cutter 1 can be finely adjusted by turning the bolts.
