TECHNICAL FIELD

[0001] The present application relates to the field of brush testing, in particular to a hair loss prevention testing machine for brush production. BACKGROUND

[0002] After the brush is produced by the automatic lifting shearing machine, a testing operation needs to be performed, wherein the hair bundle inspection is used to detect the hair bundle shedding strength, and mainly uses the experimental tension testing machine to cooperate with the brush clamp to perform the test and record the reading of the tension testing machine when the hair bundle is pulled off.

[0003] For example, a hair bundle quality detection device for brush production is disclosed in Chinese patent CN118130207A, which realizes the preparation work before the brush test through automatic cutting of the hair bundle, thereby improving the efficiency of the brush quality detection work, but it has the following defects: 1. When the clamp pulls off the hair bundle, the clamp will suddenly unload, and the impact generated by the unloading will be directly transmitted to the electric drive structure of the clamp, thereby shortening the service life of the electric drive structure; 2. The hair bundles on the strip brush are distributed in a cluster-by-cluster manner, i.e., the top ends of the hair bundles are in a scattered state, and the roots of the hair bundles are inserted into the holes of the strip brush in a gathered manner, so if the hair bundle is inserted from the top end downward, it is easy to cause the hair bundle to be squeezed and bent, which leads to the fact that the subsequently clamped hair bundle is relatively scattered, thereby affecting the accuracy of the test.

The appearances of the phrase that in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. As will be apparent to those of ordinary skill in the art, embodiments described herein can be combinable with other embodiments.

[0020] Embodiment 1: An anti-falling test machine for brush production, as shown in the figure, comprising a base 1 and a lower clamp 2; the base 1 is installed with the lower clamp 2; Figures 1-5 Embodiment 1: An anti-falling test machine for brush production, as shown in the figure, comprising a base 1 and a lower clamp 2; the base 1 is installed with the lower clamp 2; Further comprising a moving assembly; the base 1 is installed with the moving assembly; the moving end of the moving assembly is installed with two telescopic drive twos 6 arranged symmetrically, the telescopic drive two 6 is an electric drive push rod; the telescopic end of each telescopic drive two 6 is respectively installed with a connecting plate 7; each connecting plate 7 is respectively arranged below with a clamping plate 9; the connecting plate 7 and the clamping plate 9 are connected through a buffer assembly.

[0021] The moving assembly comprises a moving driving member 3, a telescopic driving member 4 and a mounting seat 5; the moving driving member 3 is mounted on the base 1; the telescopic driving member 4 is mounted on the moving end of the moving driving member 3 and is an electric driving push rod; the moving driving member 3 drives the telescopic driving member 4 to move horizontally; the mounting seat 5 is mounted on the telescopic end of the telescopic driving member 4; and two telescopic driving members 6 are both mounted on the mounting seat 5.

[0022] The buffer assembly comprises spring telescopic rods 8 and organ type air bags 11; two cylindrical grooves are formed in each of the connecting plates 7, and one spring telescopic rod 8 is mounted in each of the cylindrical grooves; the telescopic ends of the two spring telescopic rods 8 on each of the connecting plates 7 are connected with one clamping plate 9; one accommodating groove 91 is formed in each of the clamping plates 9, and one organ type air bag 11 is arranged in each of the accommodating grooves 91; the upper end of the organ type air bag 11 is connected with the connecting plate 7, and the lower end of the organ type air bag 11 is connected with the clamping plate 9.

[0023] One push plate 10 is mounted on one side of each of the clamping plates 9; and the push plate 10 is a triangular prism with a sharp tip outwardly protruding at the bottom.

[0024] In the embodiment, the application is installed beside an automatic lifting shearing machine, which is an automatic production equipment widely used for producing various industrial brushes and civilian brushes; the automatic lifting shearing machine can produce various strip brush products independently and can cut the strip brush without stopping during the production process, thereby improving the production efficiency; the automatic lifting shearing machine can accurately control the height requirement of the brush; after the strip brush is processed by the automatic lifting shearing machine, the worker carries out sampling inspection on the produced strip brush, and the application is used for testing the falling strength.

[0025] It should be known that the lower clamp 2 is mounted on the base 1 and connected with the tensile tester on the base 1; the tensile tester is used to measure the tensile force borne by the strip brush clamped on the lower clamp 2; and the content is common knowledge and will not be described here.

[0026] Firstly, the worker places the strip brush on the lower clamp 2, clamps and fixes the strip brush through the lower clamp 2, at this time, the strip brush is fixed to the specified position, then adjusts the position of the mounting seat 5 and the parts connected thereto by controlling the movement driving part 3 and the telescopic driving part one 4, so that the clamping plates 9 and the poking plates 10 are located at the rear side of the strip brush, considering that the bristles on the strip brush are distributed in clusters, that is, the top ends of the bristles are in a scattered state, and the roots of the bristles are inserted into the holes of the strip brush in a gathered state, so if the bristles are inserted from the top down, the bristles are easily squeezed and bent, which causes the subsequent clamped bristles to be relatively scattered, affecting the accuracy of the test; therefore, the poking plate 10 is additionally arranged in the present application, and the poking plate 10 is designed as a triangular prism with the bottom tip protruding outward, when the clamping plates 9 and the poking plates 10 are located at the rear side of the strip brush, then the connecting plate 7 and the parts connected thereto are moved by controlling the telescopic driving part two 6, so that the gap between the two clamping plates 9 is aligned with a certain row of bristles to be tested, then the mounting seat 5 and the parts connected thereto are moved forward by controlling the movement driving part 3, so that the poking plate 10 moves forward and is first inserted into the bristles, and the bottom tip of the protruding outward of the poking plate 10 is first inserted into the gap between the two clusters of bristles, in the forward movement of the poking plate 10, the bristles are gradually pushed away from the roots of the bristles by the edges of the poking plate 10, so that the clamping plates 9 are gradually inserted between the two rows of bristles, so that the two clamping plates 9 are located on both sides of a certain row of bristles to be tested, then the connecting plate 7 and the parts connected thereto are moved by controlling the telescopic driving part two 6, so that the two clamping plates 9 are moved close to each other to clamp and fix a certain row of bristles to be tested, so that a certain row of bristles to be tested is clamped relatively intact, solving the problem that the bristles are squeezed and bent in the existing test process, causing the clamped bristles to be scattered and affecting the test accuracy.

[0027] At this time, the certain row of bristles to be tested is clamped and isolated by the clamping plate 9, and the worker can selectively cut off the bristles at other positions according to the test requirements.

[0028] After that, the mounting seat 5 and the parts connected thereto are pulled upward by controlling the telescopic driving part one 4, since the connecting plate 7 and the clamping plate 9 are connected through the spring telescopic rod 8, when the connecting plate 7 is pulled and moved upward, the clamping plate 9 remains stationary first, so that the spring telescopic rod 8 is stretched, and when the connecting plate 7 moves upward, the upper end of the accordion air bag 11 is moved upward, so that the accordion air bag 11 is stretched and inhales air from the outside at the same time; When the hair bundle is pulled off, the maximum pulling force value of the lower clamp 2 is obtained by the pulling force tester, and the test data is recorded; since the clamping plate 9 will suddenly unload when the hair bundle is pulled off, if the clamping plate 9 is directly connected with the telescopic driving part two 6, the impact generated by the unloading will be directly transmitted to the telescopic driving part two 6 and the telescopic driving part one 4, affecting the service life of the telescopic driving part two 6 and the telescopic driving part one 4, so a buffer assembly is designed, and the buffer space is formed between the connecting plate 7 and the clamping plate 9 through the design of the spring telescopic rod 8, the air is sucked into the accordion air bag 11 when the connecting plate 7 moves up, and the air pressure is formed inside, when the clamping plate 9 is suddenly unloaded when the hair bundle is pulled off, the clamping plate 9 will slowly move up, and the spring telescopic rod 8 will slowly rebound, so as to realize the buffering effect of the clamping plate 9, thereby reducing the impact of the sudden unloading on the telescopic driving part two 6 and the telescopic driving part one 4.

[0029] Example 2: on the basis of example 1, as shown in Figures 1-5 the initial state, the lower surface of the connecting plate 7 is attached to the upper surface of the clamping plate 9, and the accordion air bag 11 is hidden in the accommodating groove 91.

[0030] Each of the accordion air bags 11 is provided with a communication pipe 12 at one end close to the clamping plate 9; each of the communication pipes 12 penetrates through the corresponding clamping plate 9, and the opening of the communication pipe 12 communicating with the outside is directed to the clamping surface of the clamping plate 9.

[0031] In this embodiment, when the connecting plate 7 moves up and drives the upper end of the accordion air bag 11 to move up, the accordion air bag 11 is stretched and sucks air at the same time, since the accordion air bag 11 sucks air from the communication pipe 12, and the opening of the communication pipe 12 is directed to the clamping surface of the clamping plate 9, so the suction negative pressure of the hair bundle can be continuously formed between the two clamping plates 9, and the clamping stability of the hair bundle is improved.

[0032] And since there is a large extrusion force between the hair bundle and the clamping plate 9 during the clamping and pulling off of the hair bundle by the clamping plate 9, after the hair bundle is pulled off, part of the hair bundle is easily attached to the clamping surface of the clamping plate 9, so in this application, after the clamping plate 9 pulls off the hair bundle, the two telescopic driving parts two 6 drive the two connecting plates 7 to move away from each other, and the spring telescopic rod 8 slowly rebounds, so that the air in the accordion air bag 11 slowly discharges from the opening of the communication pipe 12, thereby blowing the hair bundle attached to the clamping surface of the clamping plate 9 away, without the need for manual cleaning of the clamping plate 9.

[0033] Example 3: on the basis of example 2, as shown in Figures 1-5 a valve 13 is installed in the communication pipe 12, and the valve 13 is made of soft rubber; the fixed position of the valve 13 is located on the inner upper wall of the end of the communication pipe 12 directed to the clamping surface of the clamping plate 9.

[0034] The moving driving part 3 is composed of an electric slide rail installed on the base 1 and an electric slide block connected with the telescopic driving part 1, which slides on the electric slide rail to drive the telescopic driving part 1 to move.

[0035] The side of the base 1 is provided with a collecting box for collecting the fallen hair.

[0036] In the embodiment, the valve 13 is added at the opening of the communicating pipe 12, which can prevent dust from entering the organ type air bag 11 from the opening of the communicating pipe 12 in daily non-working time. When the organ type air bag 11 inhales air from the communicating pipe 12, the valve 13 bends inward. When the organ type air bag 11 exhales air from the communicating pipe 12, the valve 13 is blown outward and bends outward. The hair on the clamping surface of the clamping plate 9 is stirred by the outward bending of the valve 13, thereby assisting the removal of the hair on the clamping surface of the clamping plate 9.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit the protection scope of the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
