Description

TECHNICAL FIELD

[0001] The utility model relates to the field of cleaning agent test technology, and specifically relates to a swing device suitable for water-based cleaning agent foam test. BACKGROUND

[0002] In the research and development process of water-based cleaning agent, foam characteristics are an important factor to be investigated. Water-based cleaning agents with different formulations can produce foams with different heights, stability and other characteristics. Currently, manual testing is commonly used in the testing of water-based cleaning agents. Due to differences in force, speed and amplitude during manual operation, the results of foam testing are affected, and the actual differences between different formulations cannot be truly reflected. Therefore, mechanical devices are needed to realize bubble shaking and uniform testing environment.

[0003] The existing bubble shaking device generally realizes reciprocating motion through the vibration of a cam mechanism. Compared with hand shaking, the reciprocating motion amplitude of the cam mechanism is insufficient, and the bubble generation efficiency is low. In addition, due to the large difference in the foaming property of cleaning agents, the cam mechanism can only realize one shaking amplitude, and can only provide a single test condition for any cleaning agent, which is not sufficient for the diversity of cleaning agents in foam testing.

DETAILED DESCRIPTION

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only the preferred embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0018] This embodiment provides a swinging device suitable for foam testing of water-based cleaning agents, such as... Figures 1-3 As shown, it includes a control system, a base 1, a rotating shaft seat 8, a drive mechanism 9, a swing mechanism, and a clamping mechanism 6. The swing mechanism uses a crank-rocker mechanism to provide reciprocating motion, including a drive crankshaft 3, a drive connecting rod 4, and a swing rod 5. The drive crankshaft 3 is driven by the drive mechanism 9 to rotate. The test bottle is placed on the swing rod 5 through the clamping mechanism 6. The swing rod 5 is supported by a rotating shaft at its lower end, which is mounted on a rotating shaft seat 8 fixed on the base 1. One end of the drive connecting rod 4 is pinned to the drive crankshaft 3, and the other end is pinned to an amplitude adjustment hole 51 adapted to the set swing angle to connect to the middle of the swing rod 5. Since the swing amplitude angle is different for different lengths of the rocker arms in the crank-rocker mechanism, several amplitude adjustment holes 51 are evenly arranged in parallel in the middle of the swing rod 5 according to several preset swing amplitude angles. The appropriate swing amplitude angle is selected according to the foaming characteristics of the cleaning agent.

[0019] Single-point clamping of the test bottle is prone to tilting, and it is easy to shake and loosen during swinging. Therefore, the clamping mechanism 6 should have at least two clamping points, and their clamping center lines should be vertical and collinear. Specifically, for example... Figure 2 As shown, to facilitate quick clamping and allow for active adjustment of clamping force, the clamping mechanism 6 includes a retainer 62, two claws 61, a synchronizing block 63, a drive bolt 64, and two transmission links 65. The claws 61, synchronizing block 63, drive bolt 64, and transmission links 65 form a crank-connecting rod-slider mechanism. The claws 61 act as a crank, and the synchronizing block 63 acts as a driven slider. Under the drive and guidance of the drive bolt 64, the two claws 61 rotate to form an opening and closing clamping action. To guide and restrict the linear motion of the synchronizing block 63, the retainer 62 has an installation space in the middle. The crank-connecting rod-slider mechanism is installed in the installation space, that is, the connecting end of the claws 61 is located in the installation space, and its upper and lower ends are limited by the retainer 62. In this way, the transmission links 65 only have horizontal motion freedom. The two transmission links 65 are symmetrically arranged to jointly restrict the longitudinal movement of the synchronizing block 63 when it rotates with the drive bolt 64.

[0020] The base plate 2 is further arranged on the top end surface of the base 1 to separate the driving area and the testing area, wherein the swing mechanism and the clamping mechanism 6 thereon are arranged on one side of the base plate 2, the pivot seat 8 and the driving mechanism 9 are arranged on the other side of the base plate 2, and meanwhile, bearings can be arranged on the mounting holes on the base plate 2 when the transmission or support connection is performed through the base plate 2, so as to support the driving crankshaft 3 pin shaft and the pivot, and respectively improve the overall structural strength and the working stability of the swing mechanism;

[0021] In addition, in order to facilitate the observation of the foam height of the detection bottle in the vertical state, and facilitate the taking and placing of the detection bottle, two centering mechanisms 7 are arranged on the base plate 2 to automatically drive the swing rod 5 to return to the vertical position after the test is completed, and thus the state that the swing rod 5 returns to the vertical position is taken as the centering line, and the two centering mechanisms 7 are symmetrically arranged on the two sides of the centering line of the swing rod 5, and again referring to Figure 1 The centering mechanism 7 is a centering rod 71 rotatably arranged on the base plate 2 through a torsion spring pin shaft 72, one end of the torsion spring is anchored on the base plate 2, and the other end is anchored on the centering rod 71, the restoring force directions of the two centering mechanisms 7 are both towards the centering line, and meanwhile, the driving mechanism 9 should adopt a mechanism or device that can allow reverse dragging, and in the embodiment, a motor without a brake is preferred, and a corresponding belt reducer is arranged, the motor and the belt reducer can be arranged on the base plate 2, the motor is electrically connected with a control system, the control system at least includes a speed adjusting module and a time control module, and is used for setting the swing speed and the swing time; the centering rod 71 is in L shape or Z shape, the pin shaft connecting point of the centering rod 71 is at a certain distance from the swing rod 5, the upper end of the centering rod 71 abuts against the side surface of the swing rod 5, the centering rod 71 is arranged in the swing area of any amplitude angle of the swing rod 5, and it is ensured that the upper end of the centering rod 71 always abuts against the side surface of the swing rod 5 in the swing process, so that in any stop position, there is a centering mechanism 7 that can drive it to return to the center.
