Description

Technical Field

[0001] This utility model relates to the field of pump head detection technology, and in particular to a pump head detection device based on adaptive limit feeding. Background Technology

[0002] Bottle pump heads are widely used in people's daily lives and the pharmaceutical industry. With just a press of the hand, the liquid inside the spray bottle can be sprayed out, bringing great convenience to people's lives. The inside of the emulsion pump is assembled from a number of tiny parts.

[0003] The existing device can only be used with pump heads of a specific size and cannot be adjusted to fit the size of the pump head. This results in unstable clamping and the pump head is prone to falling during testing. The device must be replaced if the size of the pump head changes even slightly, which greatly increases the cost. Utility Model Content

[0004] This utility model discloses a pump head detection device based on adaptive limit feeding, which aims to solve the technical problems of existing devices that are only compatible with pump heads of specific sizes, cannot be adjusted to adapt to various specifications, have poor versatility, and require equipment replacement when the pump head size changes slightly, resulting in a significant increase in cost.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pump head detection device based on adaptive limit feeding, comprising a feeder, wherein the feeder is internally provided with multiple adjustment and adaptation components, each including a telescopic drive rod, the front end of which is provided with two symmetrical limit members, and a movable plate is fixedly connected to the front end of the telescopic drive rod. The inner side of the movable plate is movably connected to the outer side of the symmetrical limit members near the telescopic drive rod. Symmetrical arc-shaped fixed plates are movably connected to the outer side of each limit member. A compression spring is fixedly connected to one side of one of the arc-shaped fixed plates, and one side of the compression spring is fixedly connected to the front end of the movable plate. Upper rods are movably connected to both sides of the arc-shaped fixed plates near the telescopic drive rod, and movable rods are fixedly connected to the front ends of the upper rods. Fixed rods are movably connected to the inner sides of the movable rods, and lower rods are fixedly connected to the bottom ends of the movable rods. One end of the lower rod is movably connected to both sides of the arc-shaped fixed plate away from the telescopic drive rod.

[0006] Equipped with a feeder and adjusting components, the telescopic drive rod activates when the pump head is being conveyed. Extending or retracting the drive rod moves the moving plate forward or backward. Since the inner side of the moving plate is movably connected to the outer side of a symmetrical limiting member near the telescopic drive rod, the movement of the moving plate causes relative movement of the limiting member. As the moving plate moves, the symmetrical arc-shaped fixing plate, movably connected to the outer side of the limiting member, adjusts according to the position and size of the pump head. When the moving plate moves forward, the corresponding arc-shaped fixing plate moves closer to the pump head until it contacts the outer side of the pump head, thus limiting and fixing the pump head. A compression spring on one side of one of the arc-shaped fixing plates adjusts according to the shape of the pump head when the arc-shaped fixing plate contacts the pump head. The compression deformation caused by the position serves as a buffer and adaptation, preventing damage to the pump head. The upper rods, which are movably connected to both sides of the arc-shaped fixed plate near the telescopic drive rod, move with the movement of the arc-shaped fixed plate. The movable rod fixedly connected to the front end of the upper rod rotates around the movable connection point with the fixed rod. The lower rod fixedly connected to the bottom end of the movable rod drives the arc-shaped fixed plate away from the telescopic drive rod to move accordingly, allowing the two arc-shaped fixed plates to better cooperate, adapt to pump heads of different sizes and shapes, and maintain stable positioning of the pump head. During the process, the size can be adjusted according to the size of the pump head, adapting to various sizes and specifications of pump heads, improving the versatility of the feeder, and reducing the cost of replacing equipment due to changes in pump head size.

[0007] In a preferred embodiment, a limiting frame is fixedly connected to the opposite sides of the plurality of limiting members. The limiting frame has a circular hole, and the inner side of the circular hole is movably connected to the outer side of the telescopic drive rod. A fixed seat is fixedly connected to the outer side of the telescopic drive rod, and a turntable is fixedly connected to the top of the fixed seat. A through hole is opened on the inner side of the turntable, and a rotating rod is movably connected to the inner side of the through hole. A fixed frame is fixedly connected to the top of the rotating rod, and a drive motor is connected to the bottom of the rotating rod through a coupling. A U-shaped frame is fixedly connected to the bottom of the drive motor, and the bottom of the U-shaped frame is fixedly connected to the inner side of the bottom of the feeder. Symmetrical holes are opened on the outer side of the bottom of the feeder. A qualified feeding port is fixedly connected to the inside of the hole on the side closer to the fixed frame, and a rework port is fixedly connected to the inside of the hole on the side farther from the fixed frame.

[0008] By setting up a limit frame, fixed seat, turntable, fixed frame, rotating rod, drive motor, U-shaped frame, and rework port, when the pump head is being tested, the pump head is conveyed into the feeder. The adjusting adaptation component contacts and clamps the outside of the pump head. The rotating rod drives the turntable to rotate, and the fixed seat and telescopic drive rod fixed on the turntable also rotate accordingly, causing the clamped pump head to rotate to the testing position. When the pump head rotates to the testing position, the testing component presses the pump head to test it. After the test is completed, if the pump head is qualified, the turntable continues to rotate, aligning the pump head with the qualified feed port. The adjusting adaptation component releases the pump head, and the pump head falls into the qualified feed port. If the pump head is unqualified, the turntable rotates, aligning the pump head with the rework port. Similarly, the adjusting adaptation component releases the pump head, and the pump head falls into the rework port.

[0009] In a preferred embodiment, a detection component is provided at the bottom of the fixed frame. The detection component includes a motor frame, a servo motor is fixedly connected to the top of the motor frame, and the power output shaft of the servo motor is connected to a rotating threaded rod via a coupling. A detection frame is movably connected to the outer side of the rotating threaded rod, and limit rods are fixedly connected to both ends of the inner side of the detection frame. The limit rods are located behind the rotating threaded rod. A movable plate is movably connected to the outer side of the rotating threaded rod, and a telescopic rod is fixedly connected to the bottom of the movable plate. A buffer spring is fixedly connected to the bottom of the movable plate, and the telescopic rods are all located inside the buffer springs. A detection pressing plate is fixedly connected to the bottom of both the telescopic rods and the buffer springs.

[0010] When the pump head is pressed for testing using a detection component, the feeder transports the pump head to the detection position. The servo motor then drives the rotating threaded rod to rotate. The rotation of the threaded rod causes the movable plate to move along the axial direction of the threaded rod and the limit rod. As the threaded rod rotates, the movable plate gradually moves downward. During the descent of the movable plate, the telescopic rod and the buffer spring fixed at its bottom also move downward. When the movable plate descends to a certain position, the detection pressing plate contacts the top of the pump head. At this point, the telescopic rod begins to experience resistance from the pump head. The movable plate continues to descend, and the buffer spring begins to be compressed, generating elastic force. This elastic force is applied to the pump head through the detection pressing plate, performing the pressing test on the pump head. During the process, the pressing force applied to the pump head is precisely adjusted to ensure the accuracy and consistency of the test, effectively detecting subtle quality differences between pump heads of different specifications.

[0011] As can be seen from the above, the pump head detection device based on adaptive limit feeding provided by this utility model has the technical effect of being able to be adjusted according to the size of the pump head, adapting to pump heads of various sizes and specifications, improving the versatility of the feeder, and reducing the cost of replacing equipment due to changes in pump head size.

[0022] Reference Figure 1 and Figure 5In a preferred embodiment, a detection component 7 is provided at the bottom of the fixed frame 3. The detection component 7 includes a motor frame 701. A servo motor 702 is bolted to the top of the motor frame 701, and a rotating threaded rod 703 is connected to the power output shaft of the servo motor 702 via a coupling.

[0023] Working principle: When the pump head is being conveyed, the telescopic drive rod 901 works, driving the moving plate 903 to move, which in turn causes the limiting member 902 to move. The arc-shaped fixing plate 905 connected to the limiting member 902 adjusts its position and spacing with the moving plate 903, approaches and contacts the pump head, and plays a limiting and fixing role. The compression spring 904 on one side of the arc-shaped fixing plate 905 is compressed and deformed to avoid damage to the pump head.

When the pump head being fed is being tested, the pump head is conveyed into the feeder 1, the adjustment and adaptation component 9 contacts and clamps the outside of the pump head, the rotating rod 4 drives the turntable 2 to rotate, and the fixed seat 11 and the telescopic drive rod 901 fixed on the turntable 2 also rotate accordingly, causing the clamped pump head to rotate to the test position. When the pump head rotates to the test position, the test component 7 presses the pump head to test it. After the test is completed, if the pump head is qualified, the turntable... 2. Continue rotating to align the pump head with the qualified feed port 8. Adjust the adaptation component 9 to release the pump head, which will fall into the qualified feed port 8. If the pump head is not qualified, the turntable 2 rotates to align the pump head with the rework port 10. Similarly, adjust the adaptation component 9 to release the pump head, which will fall into the rework port 10. The feeder 1 delivers the pump head to the detection position. The servo motor 702 drives the rotating threaded rod 703 to rotate, causing the movable plate 705 to descend. The telescopic rod 706 and the buffer spring 707 at its bottom end also descend. After the detection pressing plate 708 contacts the top of the pump head, the telescopic rod 706 encounters resistance, and the movable plate 705 continues to descend. The elastic force of the buffer spring 707 is used to press and test the pump head through the detection pressing plate 708.
