Description

Technical Field

[0001] This utility model relates to the field of emulsion pump assembly technology, and in particular to a rotary assembly mechanism for an emulsion pump that is easy to replace and maintain. Background Technology

[0002] In industries such as daily chemicals and pharmaceuticals, emulsion pump heads are commonly used packaging components for liquid products, and their assembly efficiency and quality are crucial to product manufacturing. With the development of automated production technology, emulsion pump head assembly equipment is constantly being innovated. In existing technologies, such as the emulsion pump head assembly equipment disclosed in Chinese utility model patent document (publication number CN220787097U), a servo motor drives a rotary lock head to rotate, which in turn drives the emulsion pump body to rotate, realizing the threaded connection between the emulsion pump body and the pump head, effectively improving assembly efficiency.

[0003] However, this existing technology has significant drawbacks. Its rotary lock head is directly fixed to the servo motor. In actual production, due to the structural differences between various specifications and models of emulsion pump heads, lock heads of different shapes and sizes need to be matched and plugged into the emulsion pump heads to ensure assembly accuracy and stability. However, the fixed connection between the rotary lock head and the servo motor in existing equipment makes lock head disassembly extremely inconvenient. When production tasks require switching to different specifications of emulsion pump heads, operators find it difficult to quickly replace the appropriate lock head. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a rotary assembly mechanism for an emulsion pump that is easy to replace and maintain.

[0005] A rotary assembly mechanism for an emulsion pump designed for easy replacement and maintenance includes a frame, a rotating module, a turntable, a transmission module, a drive module, and a lifting module. The rotating module drives the turntable to rotate. The turntable has multiple receiving slots arranged in a circumferential array to accommodate the pump head body, and the bottom of the receiving slots is open. The transmission module includes a mounting bracket connected to the lifting module. The mounting bracket is fixedly connected to a mounting sleeve, and a transmission sleeve is rotatably disposed inside the mounting sleeve. The transmission sleeve and the mounting sleeve are detachably connected. The upper part of the transmission sleeve is provided with a coupling transmission part that is inserted and coupled to the pump head body. The drive module is drivenly connected to the transmission sleeve.

[0006] Preferably, the outer wall of the transmission sleeve is provided with an annular groove, and the mounting sleeve is provided with a plurality of mounting holes arranged in a circumferential array that communicate with the annular groove. A ball bearing that can be inserted into the annular groove is provided in the mounting hole. A limiting sleeve for driving the ball bearing to stay in the annular groove is provided on the outer side of the mounting sleeve. The upper inner wall of the limiting sleeve is provided with a clearance space. An elastic element is connected to the limiting sleeve and the mounting bracket.

[0007] Preferably, the bottom of the transmission sleeve is provided with a transmission coupling groove; the drive module includes a drive motor, and the motor shaft of the drive motor is provided with a drive head that is movably inserted into the transmission coupling groove.

[0008] Preferably, the lifting module includes a cylinder fixedly mounted on the frame, the cylinder shaft of which is connected to a lifting plate, and a mounting bracket and a drive module mounted on the lifting plate.

[0009] Preferably, the frame is equipped with guide rails, and the guide rails are slidably connected to sliding blocks, which are fixedly connected to the lifting plate.

[0010] Compared with existing technologies, this utility model's easily replaceable and maintainable emulsion pump rotary assembly mechanism, through its unique structural design, effectively overcomes the shortcomings of existing technologies, such as inconvenient disassembly of the rotary lock head and difficulty in adapting to different specifications of emulsion pump heads, and has significant beneficial effects. Firstly, the transmission sleeve and mounting sleeve in the transmission module are detachably connected. Compared to the existing technology where the rotary lock head is directly fixed to the servo motor, operators can quickly disassemble and replace the transmission sleeve according to different specifications of emulsion pump heads, greatly reducing equipment debugging time and significantly improving production efficiency; at the same time, it avoids damage to the equipment caused by frequent disassembly, reducing maintenance costs. Secondly, the coupling transmission part set on the upper part of the transmission sleeve can accurately insert and couple with the pump head body. Attached Figure Description

[0022] See Figures 1-3A rotary assembly mechanism for an emulsion pump that is easy to replace and maintain includes a frame 10, a rotating module 20, a turntable 30, a transmission module 50, a drive module 60, and a lifting module 70. The rotating module 20 drives the turntable 30 to rotate. The turntable 30 has multiple receiving slots 310 arranged in a circumferential array to accommodate the pump head body 410. The receiving slots 310 have openings at their bottoms. The transmission module 50 includes a mounting bracket 510 that is interconnected with the lifting module 70. The mounting bracket 510 is fixedly connected to a mounting sleeve 520. A transmission sleeve 530 is rotatably disposed within the mounting sleeve 520. The transmission sleeve 530 is detachably connected to the mounting sleeve 520. The upper part of the transmission sleeve 530 is provided with a coupling transmission part 532 that is inserted and coupled to the pump head body 410. The drive module 60 is drively connected to the transmission sleeve 530. In this embodiment, the transmission sleeve and the mounting sleeve in the transmission module are detachably connected. Compared with the existing technology where the rotary lock head is directly fixed to the servo motor, the operator can quickly disassemble and replace the transmission sleeve according to different specifications of emulsion pump heads, which greatly reduces equipment debugging time and significantly improves production efficiency.

[0023] In this utility model, the shape of the coupling transmission part 532 is set according to different pump head bodies 410. Its function is to transmit power with the pump head body 410 so that when the coupling transmission part 532 rotates, it can drive the pump head body 410 to rotate synchronously.

[0024] In practical use, the pump head body 410 with the pusher 420 is first grasped by the robotic arm and placed in the receiving groove 310. Then, under the action of the rotating module 20, the turntable 30 moves the product above the transmission sleeve 530. Under the action of the lifting module 70, the transmission sleeve 530 moves upward and inserts into the pump head body 410 for coupling. Finally, driven by the drive module 60, the transmission sleeve 530 drives the pump head body 410 to rotate relative to the pusher 420 for threaded connection. The pusher 420 can be fixed by pressing down using existing technology.

[0025] In this invention, the rotating module 20 can be an existing indexing plate, which has precise rotation angle control and can accurately drive the product to rotate above the transmission sleeve 530.

[0026] See Figure 3The transmission sleeve 530 has an annular groove 531 on its outer wall. The mounting sleeve 520 has a plurality of mounting holes 521 arranged in a circumferential array, communicating with the annular groove 531. A ball bearing 540 is inserted into the annular groove 531 within each mounting hole 521. A limiting sleeve 550 is fitted on the outer side of the mounting sleeve 520 to keep the ball bearing 540 within the annular groove 531. The upper inner wall of the limiting sleeve 550 has a clearance space 570. An elastic element 560 connects the limiting sleeve 550 to the mounting bracket 510. In this embodiment, the elastic element 560 constrains the limiting sleeve 550 to a locked position. When the limiting sleeve 550 is in the locked position, it forces the ball bearing 540 to be inserted into the annular groove 531, preventing it from moving outward. When it is necessary to disassemble the transmission sleeve 530, the limiting sleeve 550 is pressed down to move it downward, thereby making the clearance space 570 opposite to the mounting hole 521. At this time, the ball located in the mounting hole 521 can move into the clearance space 570, that is, the ball 521 disengages from the annular groove 531, thus completing the unlocking.

[0027] Furthermore, the elastic element 560 is a spring.

[0028] Furthermore, the diameter of the mounting hole 521 facing the annular groove 531 is smaller than the maximum outer diameter of the ball 540. This design prevents the ball 540 from passing inward through the mounting hole 521 and falling into the mounting sleeve 520.

[0029] See Figure 3 The bottom of the transmission sleeve 530 is provided with a transmission coupling groove 533; the drive module 60 includes a drive motor 610, and the motor shaft of the drive motor 610 is provided with a drive head 620 that is movably inserted into the transmission coupling groove 533. During assembly, the transmission sleeve 530 is inserted into the mounting sleeve 520 from top to bottom. As the transmission sleeve 530 moves downward, it continues until the transmission coupling groove 533 and the drive head 620 are engaged, thus completing the assembly.

[0030] See Figure 1 The lifting module 70 includes a cylinder 740 fixedly mounted on the frame 10. The cylinder shaft of the cylinder 740 is connected to a lifting plate 730. The mounting bracket 510 and the drive module 60 are mounted on the lifting plate 730.

[0031] Furthermore, the mounting bracket 510 is mounted on the lifting plate 730.

[0032] See Figure 1 The frame 10 is provided with a guide rail 710, and a sliding block 720 is slidably connected to the guide rail 710. The sliding block 720 is fixedly connected to the lifting plate 730.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
