Description

Technical Field

[0001] This invention relates to the field of filling equipment technology, and more specifically to a filling and sealing device. Background Technology

[0002] Filling typically involves multiple processes, such as conveyor belts that move objects to the required workstations, where mechanisms then perform predetermined actions on the objects. Filling lines generally occupy a large area and are inconvenient to install in factory layouts, so improvements are needed. Summary of the Invention

[0003] To address at least one of the aforementioned technical deficiencies, the present invention provides the following technical solution:

[0004] This application discloses a filling and sealing device, including a feeding assembly, a blow molding assembly, a filling assembly, a tube pulling assembly, and a stamping assembly;

[0005] The feeding assembly includes a feeding mechanism and an extrusion die. The feeding mechanism is used to feed material to the extrusion die, and the extrusion die is used to extrude the material fed by the feeding mechanism into a tube.

[0006] The blow molding assembly is located below the extrusion mold. The blow molding assembly includes a base, a molding mold, a drive mechanism, and a lifting mechanism. The drive mechanism is provided on the base and is connected to the molding mold to drive it to open and close. The lifting mechanism is connected to the base to drive the base to move up and down and cooperate with the molding mold to shape the object falling from the extrusion mold into the desired shape.

[0007] The filling assembly includes a filling needle, which is connected to an extrusion die. The material conveyed by the feeding assembly is fed into the cavity of the extruded object through the filling needle.

[0008] The tube drawing assembly includes a second lifting mechanism and a clamping mechanism. The second lifting mechanism is connected to the clamping mechanism to drive it to move up and down. The clamping mechanism is used to clamp the object falling from the forming mold. The second lifting mechanism moves the clamping mechanism to send the clamped object to the stamping assembly.

[0009] The stamping assembly is used to separate rows of objects.

[0010] This design incorporates the functional components of a filling and sealing device, integrating a feeding assembly, a blow molding assembly, a filling assembly, a tube pulling assembly, and a stamping assembly. In operation, the feeding assembly initially forms a tubular object, which is then pressed into the desired shape by the blow molding assembly. The filling assembly uses a filling needle to input the required material into the cavity of the object formed by the blow molding assembly. The tube pulling assembly transfers the object formed by the blow molding assembly to the stamping assembly, where the stamping assembly separates the pressed objects. This design improves the automation level and efficiency of the filling process while significantly reducing the floor space required.

[0011] Furthermore, the extrusion mold includes a main body and a mold column. A cavity is provided inside the main body, and the discharge port of the cavity is located at the bottom surface of the main body. The mold column is arranged along the longitudinal direction of the main body inside the cavity, and a forming cavity in which the extruded material is in the form of a tube is formed between the periphery of the mold column and the cavity wall. The output port of the material conveying mechanism is connected to the forming cavity. The filling needle is connected to the mold column to fill the object formed through the forming cavity. The filling needle is connected to the mold column to facilitate filling into the cavity of the formed object. The reasonable design facilitates the layout.

[0012] Furthermore, the filling assembly includes a material conveying assembly connected to the filling needle. The material conveyed by the material conveying assembly is fed into the cavity of the extruded object through the filling needle. Common material conveying assemblies include auger conveyors, such as motor-driven augers that convey materials to the extrusion die. Of course, other pressurized conveying types can also be selected.

[0013] Furthermore, the top wall of the cavity is formed with an installation port, the column has a longitudinally penetrating material conveying hole, and the filling needle is connected to the material conveying hole from the installation port, which facilitates the installation and filling of the column.

[0014] Furthermore, the forming mold includes a left mold and a right mold, and a driving mechanism drives the left mold and the right mold to open and close. The faces of the left mold and the right mold facing each other have grooves for secondary forming of the object formed by the extrusion mold. The driving mechanism drives the left mold and the right mold to separate to both sides, and the space between the left mold and the right mold is below the cavity discharge port. The driving mechanism drives the left mold and the right mold to merge so that the object falling from the cavity discharge port is formed secondary.

[0015] Furthermore, the drive mechanism one includes a horizontal displacement component, which is disposed opposite to the base. The horizontal displacement component includes a telescopic mechanism one and a telescopic mechanism two. The telescopic mechanism one is disposed on the base, and the telescopic mechanism two is disposed at the moving end of the telescopic mechanism one. The moving end of the telescopic mechanism two is connected to the corresponding left mold or right mold in the forming mold. The two telescopic mechanisms work together to adjust the movement range, making it more convenient to use.

[0016] Furthermore, a fixed plate is provided at the moving end of the telescopic mechanism one, and a telescopic mechanism two is provided on the fixed plate. A guide mechanism one for guiding movement is provided between the left mold, the right mold and the corresponding fixed plate, and a guide mechanism two for guiding movement is provided between the fixed plate and the base. The addition of the fixed plate facilitates the installation of the telescopic mechanism two, and the addition of the guide mechanism helps to improve the stability of movement.

[0017] Furthermore, a tubular object is formed using an extrusion die. The tubular object falls to the forming die under its own weight, and the forming die further presses the lower part of the tubular object. Material is fed into the cavity of the secondary-pressed object through a filling component. A lifting mechanism drives the forming die downward and opens the left and right molds in the forming die to move the secondary-pressed object to the tube-pulling component. The lifting mechanism resets the forming die and the left and right molds merge to further press the tubular object that has moved downward from the extrusion die, while simultaneously pressing the upper part of the secondary-pressed object. The tube-pulling component moves the clamped object downward to the stamping component. This optimized process allows the upper and lower parts of the object to be formed in steps, which helps to improve efficiency.

[0018] Furthermore, the clamping mechanism includes a telescopic mechanism three, a telescopic mechanism four, a connecting rod one, a connecting rod two, a clamping block one, a clamping block two, and a fixed frame. The fixed frame is connected to the moving end of the lifting mechanism two. The fixed frame is equipped with telescopic mechanisms three and four, and the moving ends of telescopic mechanisms three and four face opposite directions. The moving end of telescopic mechanism three is connected to connecting rod one, and the moving end of telescopic mechanism four is connected to connecting rod two. A clamping block one is provided on connecting rod one, and a clamping block two is provided on connecting rod two. The telescopic mechanisms three and four drive connecting rod one and connecting rod two to move synchronously, causing clamping blocks one and two to separate or merge. Clamping blocks one and two are located below the forming mold to clamp the object formed at the forming mold. The lifting mechanism two drives the fixed frame to move down to move the object clamped by clamping blocks one and two to the stamping assembly. The structure of the clamping mechanism is designed to facilitate cooperation with the blow molding mold and the stamping assembly, and to facilitate layout.

[0019] Furthermore, the first connecting rod includes a longitudinal part and a horizontal part. The two ends of the longitudinal part are respectively connected to the horizontal part and the clamping block, and the horizontal part is connected to the moving end of the telescopic mechanism three. The second connecting rod includes a longitudinal part, a horizontal part, and a connecting part. The two ends of the longitudinal part are respectively connected to the clamping block and the horizontal part. The connecting part is longitudinally arranged and is respectively connected to the moving end of the horizontal part and the telescopic mechanism four. The structure of the first and second connecting rods is designed to facilitate the layout to cooperate with the blow molding die and the stamping assembly.

[0020] Furthermore, it also includes a guide mechanism three. The guide mechanism three is provided between the horizontal part one, the horizontal part two and the fixed frame to guide the movement, thereby improving the stability of movement.

[0021] For stamping components, such as common shifting mechanisms that drive the cutting blade, specifically using telescopic cylinders to move the cutting blade downwards to cut the pressed and formed objects. The stamping assembly preferably adopts the following structure: The stamping assembly includes a first conveyor line, a pushing mechanism, and a downward cutting mechanism. The first conveyor line is located within the working range of the tube drawing assembly to receive the objects transferred by the tube drawing assembly. The pushing mechanism includes a first longitudinal shifting mechanism, a first horizontal shifting mechanism, and a pusher. The first longitudinal shifting mechanism is provided with a first horizontal shifting mechanism, and the first horizontal shifting mechanism is provided with a pusher. The first longitudinal shifting mechanism moves downwards, and the second horizontal shifting mechanism simultaneously causes the pusher to abut against the objects transferred on the first conveyor line. The second horizontal shifting mechanism moves the pusher horizontally, and the pusher simultaneously pushes the objects on the first conveyor line into the working range of the downward cutting mechanism. The downward cutting mechanism includes a mounting base, a second longitudinal shifting mechanism, and a first cutter at its moving end. The mounting base is provided with a placement area. The pushing mechanism transfers the objects to the placement area. In the initial state, the first cutter is located above the placement area. The second longitudinal shifting mechanism moves the first cutter downwards to cut the objects in the placement area. The conveyor line is similar to the common chute type. In the initial stage, the first pressed and shaped object is manually moved to the area under the pusher claw, and then the pusher claw moves it forward step by step to the pressing and cutting mechanism. Of course, the conveyor line can also be a common conveyor belt type, where the first pressed and shaped object is moved down to one end of the conveyor line, and then moved to the area under the pusher claw by the conveyor line, and then pushed forward by the pusher claw.

[0022] Furthermore, it also includes a waste removal mechanism, which includes a longitudinal shifting mechanism three and a cutter two at its moving end. The longitudinal shifting mechanism three moves the cutter two downward to remove the part of the object that has passed the downward cutting mechanism. The excess part is removed by the longitudinal shifting mechanism three in conjunction with the cutter two, thereby improving processing efficiency.

[0023] Furthermore, it also includes a second conveyor line. The placement seat in the material placement area is provided with a discharge hole for the cut objects to pass through. The second conveyor line is located below the discharge hole. The second conveyor line is such as a common conveyor belt type or roller conveyor type. The cut single tubes and other parts fall to the second conveyor line and are then transported to the required position by the second conveyor line.

[0024] Furthermore, it also includes a heating mechanism. The heating mechanism is provided on the material conveying mechanism to heat the material conveyed by the material conveying mechanism. The heating can be carried out according to the properties of the material, which facilitates the subsequent extrusion molding steps.

[0025] Furthermore, it also includes a housing, in which a blow molding assembly, a filling assembly, a tube drawing assembly, and a stamping assembly are arranged. In the feeding assembly, the material conveying mechanism and the extrusion die protrude from the top surface of the housing. The housing is added to reduce interference from external factors and improve safety.

[0043] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0044] Example 1

[0045] like Figure 1 , Figure 2 As shown, the filling and sealing device in this example includes a feeding assembly 2, a blow molding assembly 5, a filling assembly 4, a tube pulling assembly 6, and a stamping assembly 7. To improve safety performance and reduce interference from external factors, a box-shaped housing 1 is added in this example. The tube pulling assembly 6, the stamping assembly 7, and the blow molding assembly 5 are all located inside the housing 1. The filling assembly 4 and part of the feeding assembly 2 are located outside the housing 1. Preferably, a cabinet door 3 is hinged to the side of the housing 1 to facilitate maintenance of the internal mechanism.

[0046] like Figure 3 , Figure 4As shown, the feeding assembly 2 includes a conveying mechanism and an extrusion die 22. The conveying mechanism feeds material to the extrusion die, and the extrusion die 22 extrudes the material conveyed by the conveying mechanism into a tube. The conveying mechanism is a common auger conveyor type, driven by a motor or other power mechanism to rotate the auger inside the conveying pipe, thereby moving the material in the conveying pipe forward to the extrusion die. A material cylinder may be installed on the conveying pipe for convenient feeding. A heating mechanism 21 may be installed on the conveying pipe; the heating mechanism may be steam-heated or electric-heated, and can be selected from the market according to requirements, which will not be elaborated further here.

[0047] For extrusion die 22, such as Figure 4 As shown, it includes a main body 221 and a molded column 222. The main body 221 is rectangular and has a pre-formed cavity inside, i.e., a molded cavity. The material outlet 224 of the molded cavity is located at the bottom surface of the main body 221. The molded column 222 is fixed along the longitudinal direction of the main body 221 inside the molded cavity. The specific configuration of the molded column can be determined according to the shape of the object to be molded. In this example, the molded column 222 adopts an elliptical cylinder configuration. The periphery of the molded column 222 and the cavity wall form a molding cavity 225 in which the extruded material is a tube. The side wall of the molding cavity 225 forms a material inlet 226 to be connected to the output port of the conveying mechanism. The material input by the conveying mechanism is formed into a thin-walled tube-shaped object in the molding cavity.

[0048] In the filling assembly 4, the filling needle 41 is connected to the mold post 222 to fill the object formed through the molding cavity. For example, a longitudinally penetrating material feeding hole 223 is formed on the mold post, and the filling needle 41 is inserted into the feeding hole and fixed. The material input from the filling needle is discharged through the discharge chamber. The filling needle protrudes outward from the top surface of the housing for easy connection with the material conveying assembly in the canning assembly. To facilitate the installation of the filling needle, an installation port is formed on the top wall of the cavity in this example, and a longitudinally penetrating material feeding hole 223 is formed at the mold post. The filling needle 41 extends from the installation port and is inserted into the feeding hole and fixed. The material conveying assembly can be selected from the market as needed, such as gravity filling type, pressure filling type, or vacuum filling type. This example uses a pressure filling type material conveying assembly, which is connected to the material container 42 on the top surface of the housing for receiving the corresponding material.

[0049] For blow-molded components, such as Figure 2 , Figure 5 , Figure 6 As shown, the blow molding assembly 5 is located below the extrusion mold 22. The blow molding assembly 5 includes a base 53, a molding mold 52, a drive mechanism 1, and a lifting mechanism 1 51. The drive mechanism 1 is installed on the base 53 and is connected to the molding mold 52 to drive it to open and close. The molding mold 52 is located below the extrusion mold 22. The lifting mechanism 1 51 is connected to the base 53 to drive the base to move up and down, and cooperates with the molding mold to shape the object falling from the extrusion mold into the required shape.

[0050] The seat body is frame-shaped, and a lifting mechanism 51 is installed in the housing 1 cavity on one side of the seat body 53. The lifting mechanism is like a common hydraulic cylinder, but other types of lifting mechanisms can also be used. The moving end of the lifting mechanism 51 is connected to the side of the seat body 53. A forming mold 52 and a drive mechanism are installed in the frame opening of the seat body.

[0051] For the forming mold, it includes a left mold 525 and a right mold 526, and a drive mechanism drives the left mold 525 and the right mold 526 to open and close. The faces of the left mold 525 and the right mold 526 facing each other have grooves for secondary forming of the object formed by the extrusion mold, such as forming multiple small tubes side by side. The drive mechanism drives the left mold and the right mold to separate to both sides, and the space between the left mold and the right mold is below the cavity discharge port 224. When the thin-walled tube formed in the cavity falls between the left mold 525 and the right mold 526, the drive mechanism drives the left mold and the right mold to merge so that the object falling from the cavity discharge port is secondary formed.

[0052] The drive mechanism can be selected from the market according to the requirements. Preferably, the drive mechanism includes a horizontal shifting component, which is mounted on the base 53. The horizontal shifting component includes a telescopic mechanism 1 523 and a telescopic mechanism 2 524. The telescopic mechanism 1 523 is horizontally fixed on the base 53, and the telescopic mechanism 2 524 is horizontally installed at the moving end of the telescopic mechanism 1 523. The moving end of the telescopic mechanism 2 524 is connected to the corresponding left or right mold in the molding die. For example, the telescopic mechanism 2 on the left side of the frame opening is connected to the adjacent left mold, and the telescopic mechanism 2 on the right side of the frame opening is connected to the adjacent right mold. The telescopic mechanism 1 can adjust the opening and closing degree of the left and right molds by a large amount, and the telescopic mechanism 2 can adjust the opening and closing degree of the left and right molds by a small amount.

[0053] To facilitate the installation of the second telescopic mechanism, a fixed plate 522 is installed at the moving end of the first telescopic mechanism 523 in this example. The second telescopic mechanism 524 is installed on the fixed plate. A guide mechanism 527 for guiding movement is installed between the left mold, the right mold and the corresponding fixed plate. The first guide mechanism is like a common guide post or guide cylinder. A guide mechanism 528 for guiding movement is installed between the fixed plate 522 and the base 53. It is also like a guide post or guide cylinder, which helps to improve the stability of movement.

[0054] For the above-mentioned telescopic mechanisms, such as telescopic mechanism one and telescopic mechanism two, telescopic hydraulic cylinders are used.

[0055] For tubular assemblies, such as Figure 7 , Figure 8As shown, the tube drawing assembly 6 includes a second lifting mechanism 62 and a clamping mechanism 61. The second lifting mechanism 62 is connected to the clamping mechanism to drive it to move up and down. The clamping mechanism 61 is used to clamp the object falling from the forming mold. The second lifting mechanism moves the clamping mechanism to send the clamped object to the stamping assembly. For the second lifting mechanism, a common type is the motor-driven lifting mechanism, such as... Figure 2 As shown, it is located at the lower side of the molding die. For the clamping mechanism, clamping mechanism 61 includes telescopic mechanism three 611, telescopic mechanism four 612, connecting rod one 616, connecting rod two 617, clamping block one 614, clamping block two 615 and fixing frame 613. The fixing frame 613 is connected to the moving end of lifting mechanism two 62. The fixing frame can be slidably connected to the cavity wall of the housing to improve the stability of movement. The configuration of the fixing frame can be selected according to the requirements, such as the strip shape in this example.

[0056] Telescopic mechanism three 611 and telescopic mechanism four 612 are installed on the fixed frame 613, such as Figure 8 As shown, telescopic mechanisms 3 (611) and 4 (612) are arranged vertically at intervals. The moving ends of telescopic mechanisms 3 and 4 face opposite directions. The moving end of telescopic mechanism 3 (611) is connected to connecting rod 1 (616), and the moving end of telescopic mechanism 4 (612) is connected to connecting rod 2 (617). Clamping block 1 (614) is installed on connecting rod 1, and clamping block 2 (615) is installed on connecting rod 2. Telescopic mechanisms 3 and 4 drive connecting rod 1 and connecting rod 2 to move synchronously, causing clamping blocks 1 and 2 to separate or merge. Clamping blocks 1 and 2 are located below the forming mold to clamp the object formed at the forming mold. After clamping blocks 1 and 2 clamp the object falling from the forming mold, lifting mechanism 2 drives the fixed frame to move down to move the object clamped by clamping blocks 1 and 2 to the stamping assembly. Clamping blocks 1 and 2 then release, allowing the clamped object to fall to the stamping assembly.

[0057] To facilitate layout and coordination with stamping components, forming dies, etc., the preferred configuration of the connecting rod is as follows: connecting rod 616 includes a longitudinal part 6161 and a horizontal part 6162. The longitudinal part is a longitudinally extending component, and the horizontal part is a horizontally extending component. The tail end of the longitudinal part is connected to the head end of the horizontal part to form an L-shape. The head end of the longitudinal part is connected to the clamping block 1, and the tail end of the horizontal part is connected to the moving end of the telescopic mechanism 611. To improve stability, a configuration of two parallel connecting rods 611 can be selected. Linkage 2 617 includes a longitudinal section 2 6171, a horizontal section 2 6172, and a connecting section 6173. The first end of the longitudinal section 2 is connected to the clamping block 2, and its tail end is connected to the horizontal section 2. The connecting section 6173 is longitudinally arranged, and its first and last ends are connected to the moving ends of the horizontal section 2 6172 and the telescopic mechanism 4 611. The longitudinal section 2 is parallel to the longitudinal section 1, and the horizontal section 1 is parallel to the horizontal section 2. Similarly, configurations of two horizontal sections 2 side by side and two longitudinal sections 2 side by side can be selected to improve the stability of the movement of the clamping block 2. A guide mechanism 3 618 can also be added. The guide mechanism 3 is a sliding bearing structure mounted on a bearing seat. The guide mechanism 3 618 is mounted on the fixed frame 613. The horizontal section 1 and the horizontal section 2 are connected to the sliding bearing in the guide mechanism 3 to improve the movement stability.

[0058] For telescopic mechanisms three and four, such as the common telescopic cylinder type.

[0059] like Figure 2 , Figure 9 , Figure 10 , Figure 11 As shown, in this example, the stamping component 7 is used to separate rows of objects. For example, the blow molding component presses the tube formed at the extrusion die into a configuration of multiple small tubes arranged side by side. The stamping component is used to separate the small tubes arranged side by side, such as by directly cutting them into a single tube or two tubes arranged side by side.

[0060] For the stamping assembly 7, a common type is the cutting blade driven by a shifting mechanism, specifically, a downward-moving cutting blade is moved by a telescopic cylinder to cut the pressed and formed object. Preferably, the stamping assembly structure shown in this example is adopted. Specifically, the stamping assembly 7 includes a conveyor line 71, a pushing mechanism 72, and a downward-pressing and cutting mechanism 73. The conveyor line 71 is located within the working range of the drawing assembly 6 to receive the object transferred by the drawing assembly. The conveyor line 71 is a common chute type. Initially, the object being pressed and formed for the first time is manually moved to below the pusher claw, and then the pusher claw gradually moves forward to the downward-pressing and cutting mechanism. Of course, the conveyor line 71 can also be a common conveyor belt type, where the object being pressed and formed for the first time moves down to one point on the conveyor line, is moved by the conveyor line 71 to below the pusher claw, and then is pushed forward by the pusher claw.

[0061] The pushing mechanism 72 includes a longitudinal shifting mechanism 721, a horizontal shifting mechanism 722, and a pusher 723. The horizontal shifting mechanism 722 is installed at the moving end of the longitudinal shifting mechanism 721, and the pusher 723 is fixed at the moving end of the horizontal shifting mechanism 722. The longitudinal shifting mechanism moves vertically downward, and the horizontal shifting mechanism moves horizontally, causing the pusher to abut against the object being conveyed on the conveyor line. The horizontal shifting mechanism 722 moves horizontally, and the pusher 723 moves horizontally, simultaneously pushing the object on the conveyor line 71 into the working range of the pressing and cutting mechanism 73. The longitudinal shifting mechanism is like a common telescopic cylinder, the horizontal shifting mechanism is also like a common telescopic cylinder, and the pusher is like a common plate. Preferably, the bottom surface of the pusher plate is formed with teeth at intervals to better abut against and push objects with multiple tubes side by side.

[0062] The pressing and cutting mechanism 73 includes a mounting base 732, a second longitudinal shifting mechanism 731, and a first cutter 733 at its moving end. In the initial state, a material placement area 76 is defined at the mounting base below the first cutter 733. The pushing mechanism moves the object to the material placement area. The second longitudinal shifting mechanism moves the first cutter down to divide the object in the material placement area. The specific configuration of the first cutter can be selected according to the division requirements. The second longitudinal shifting mechanism is like a common telescopic cylinder, which will not be described in detail here.

[0063] A second conveyor line 75 can also be added, such as a common conveyor belt type. A discharge hole is formed at the placement seat 732 in the material placement area 76 for the cut objects to pass through. The second conveyor line 75 is located below the discharge hole. The tube formed after being cut by the pressing and cutting mechanism falls from the discharge hole onto the second conveyor line and is then conveyed out from the opening on the side of the shell.

[0064] Preferably, a waste removal mechanism 74 is added. The waste removal mechanism 74 includes a longitudinal shifting mechanism three 741 and a cutter two 742 at its moving end. The longitudinal shifting mechanism three 741 moves the cutter two 742 downward to cut off the part of the object that has passed over the pressing and cutting mechanism. The longitudinal shifting mechanism three is like a common telescopic cylinder, and the longitudinal shifting mechanism three 741 is located side by side with the longitudinal shifting mechanism two 731. The objects pressed by the blow molding component are often in strips. If the residue after the pressing and cutting mechanism is not cut off, it is easy to roll up into a ball, which takes up a lot of volume. Therefore, the waste removal mechanism cuts it off for easy cleaning.

[0065] In terms of usage process, common scenarios include: initially forming a tubular object through a feeding assembly; pressing the tubular object into the desired shape using a blow molding assembly; inputting the required material into the cavity of the object formed by the blow molding assembly through a filling needle in the filling assembly; and transferring the object formed by the blow molding assembly to the stamping assembly using a tube pulling assembly, whereby the stamping assembly separates the objects that have been pressed into rows.

[0066] The preferred process is as follows: A tubular object is formed by an extrusion mold in the feeding assembly. The tubular object falls to the forming mold under its own weight. The forming mold then performs a secondary pressing on the lower part of the tubular object. Material is fed into the cavity of the secondary-pressed object through a filling assembly. A lifting mechanism drives the forming mold downwards, and the left and right molds in the forming mold open to allow the secondary-pressed object to move to the tube-pulling assembly. The lifting mechanism resets the forming mold, and the left and right molds merge to perform a secondary pressing on the tubular object that has moved downwards from the extrusion mold.
