Description

Technical Field

[0001] This utility model relates to the fields of food and pharmaceutical packaging, and in particular to a multi-mold blow-fill-seal integrated extruder assembly. Background Technology

[0002] When the blow-fill-seal equipment is in full production, the extruder moving part needs to be moved to the front working position to enable the filling operation. When it is necessary to change the filling needle or for maintenance, the extruder moving part needs to be moved to the rear working position to enable the filling needle replacement or maintenance operation.

[0003] However, the extruder movement mechanism in conventional blow-fill-seal equipment currently used in the industry is generally manually driven, requiring operators to repeatedly turn gears with a handle to move the equipment forward and backward. This manual operation mode not only consumes a lot of manpower, but also results in slow and inefficient movement, making it difficult to meet the demands of modern production for rapid equipment response and automated control. Furthermore, the instability of manual operation can easily lead to equipment positioning deviations, affecting filling accuracy and production quality. In addition, frequent manual movement during equipment maintenance further prolongs downtime and reduces overall production efficiency.

[0004] Therefore, a multi-die blow-fill-seal integrated extruder assembly is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a multi-die blow-fill-seal integrated extruder component to improve the automation level of the equipment, thereby shortening the maintenance time and improving the filling accuracy and maintenance efficiency of the equipment.

[0006] To solve the above-mentioned technical problems, this utility model provides a multi-die blow-fill-seal integrated extruder assembly, including an extruder body and a servo drive mechanism;

[0007] The servo drive mechanism includes a drive base, a support plate, a ball screw, and a drive component;

[0008] The ball screw is rotatably mounted on the drive seat via the drive component;

[0009] The support plate is slidably mounted on the drive seat and threadedly connected to the ball screw, and its upper surface is used to connect to the extruder body;

[0010] The driving component includes a servo motor and a gear reducer;

[0011] The output end of the servo motor is connected to the gear reducer, and the output end of the gear reducer is connected to the ball screw via a coupling.

[0012] Furthermore, the drive seat includes a first support plate and a second support plate;

[0013] Between the first support plate and the second support plate of the ball screw;

[0014] The first support plate of the drive component is located on the side away from the second support plate.

[0015] Furthermore, both the first support plate and the second support plate have bearing seats for mounting the ball screw.

[0016] Furthermore, anti-collision rings are provided on the side of the first support plate and the second support plate that are close to each other, and the anti-collision rings are sleeved on the outside of the ball screw.

[0017] Furthermore, a U-shaped oil baffle plate is fixedly installed between the first support plate and the second support plate;

[0018] The oil baffle plate is located below the ball screw.

[0019] Furthermore, it also includes inductive sensors, of which two are provided, for detecting whether the extruder body has moved into position under different operating conditions.

[0020] Furthermore, it also includes two parallel sliding rails;

[0021] The extruder body is slidably connected to the slide rail;

[0022] The drive seat is located between the two slide rails.

[0023] Furthermore, an auxiliary support frame for supporting the extruder body is slidably mounted on the slide rail.

[0024] Compared with the prior art, the present invention has at least the following beneficial effects:

[0025] By setting up a drive component including a servo motor and a gear reducer, and combining it with a ball screw and a support plate to form a transmission structure, the extruder body can achieve precise forward and backward movement through automated drive, replacing the traditional manual gear-operating mode. This can effectively improve the automation level of the equipment and correspondingly shorten the maintenance time, thereby improving the filling accuracy and maintenance efficiency of the equipment.

[0026] In addition, by setting two inductive sensors to detect whether the extruder body has moved to the correct position under different working conditions, it can work with the controller to control the servo motor, so that the extruder body remains relatively fixed after moving to the predetermined position, thereby further improving the filling accuracy. Furthermore, by setting anti-collision rings to reduce mechanical collision damage, the service life of the mechanism can be extended. Attached Figure Description

[0031] The multi-die blow-fill-seal integrated extruder assembly of this utility model will now be described in more detail with reference to the schematic diagrams, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the utility model.

[0032] Furthermore, based on the teachings of this specification, those skilled in the art can form new technical solutions through cross-combination of different implementation methods without creating technical contradictions. Such variations should all be considered to fall within the protection scope of this patent.

[0033] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0034] like Figures 1 to 3 As shown in the figure, this utility model embodiment proposes a multi-die blow-fill-seal integrated extruder assembly, including an extruder body 1 and a servo drive mechanism.

[0035] The servo drive mechanism includes a drive base, a support plate 3, a ball screw 4, and a drive component.

[0036] Specifically, the ball screw 4 is rotatably mounted on the drive seat via the drive component, that is, the ball screw 4 acts as a transmission component to drive the bearing plate 3 to slide along the axis of the ball screw 4, thereby realizing the movement of the extruder body 1 to facilitate filling or maintenance operations.

[0037] In this embodiment, the support plate 3 is slidably mounted on the drive seat and threadedly connected to the ball screw 4, with its upper surface used for connection to the extruder body 1. That is, by setting the support plate 3 as a supporting component to mount the extruder body 1, the movement of the support plate 3 synchronously drives the extruder body 1 to move, facilitating subsequent filling or maintenance operations.

[0038] It should be noted that the driving components include a servo motor 5 and a gear reducer 6.

[0039] The output end of the servo motor 5 is connected to the gear reducer 6, and the output end of the gear reducer 6 is connected to the ball screw 4 through the coupling 7. That is, the servo motor 5 and the gear reducer 6 constitute a power output source to control the rotation of the ball screw 4.

[0040] Specifically, when filling is required, the servo motor 5 drives the gear reducer 6, which transmits power to the ball screw 4 through the coupling 7. Under the limiting action of the thread and the drive seat, the bearing plate 3 moves forward in a straight line until it reaches the preset position. Then, it can be detected by the detection mechanism, which then transmits the signal to the controller, and the controller controls the servo motor 5 to stop running to ensure the filling accuracy of the extruder body 1.

[0041] When the extruder body 1 needs to be pulled out for replacement of the filling needle or other maintenance, the servo motor 5 reverses the drive of the gear reducer 6 according to the controller's instructions, and then transmits the power to the ball screw 4 through the coupling 7, so that the bearing plate 3 moves backward in a straight line until it moves back to the preset position. Then, it is detected by another detection mechanism, and the signal is transmitted to the controller through the detection mechanism. The controller then controls the servo motor 5 to stop running, so that the extruder body 1 can accurately reach the predetermined position, which is convenient for replacing the filling needle or other maintenance work.

[0042] In a specific example, the detection mechanism is set as an inductive sensor 11, and there are two inductive sensors 11, which are used to detect whether the extruder body 1 has moved into place under different working conditions.

[0043] It should be noted that the detection mechanism can also be set as a proximity switch sensor, which is a conventional technical means in the existing technology, so it will not be elaborated here.

[0044] In other embodiments, a specific drive seat is proposed to further improve the transmission effect.

[0045] Specifically, the drive seat includes a first support plate 21 and a second support plate 22.

[0046] The ball screw 4 is located between the first support plate 21 and the second support plate 22, with the first support plate 21 of the drive member located away from the second support plate 22.

[0047] It should be noted that both the first support plate 21 and the second support plate 22 have bearing seats 8 for mounting the ball screw 4.

[0048] In other embodiments, the first support plate 21 and the second support plate 22 are further defined to extend the service life of the device.

[0049] Specifically, anti-collision rings 9 are provided on the side of the first support plate 21 and the second support plate 22 that are close to each other, and the anti-collision rings 9 are sleeved on the outside of the ball screw 4.

[0050] In addition, a U-shaped oil baffle plate 10 is fixedly installed between the first support plate 21 and the second support plate 22. The oil baffle plate 10 is located below the ball screw 4 and is used to collect the lubricating oil on the surface of the ball screw 4 to prevent contamination of the machine.

[0051] In a further embodiment, the multi-die blow-fill-seal integrated extruder assembly also includes two parallel slide rails 12.

[0052] The extruder body 1 is slidably connected to the slide rail 12, so that the extruder body 1 can only move along a predetermined trajectory.

[0053] Furthermore, the drive seat is located between the two slide rails 12 to achieve movement control of the extruder body 1.

[0054] In a further embodiment, an auxiliary support frame 13 for supporting the extruder body 1 is slidably mounted on the slide rail 12.

[0055] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
