Description

Technical Field

[0001] The invention relates to the technical field of brush quality detection, in particular to a quality detection device for finished bristle brushes. Background Art

[0002] A boar bristle brush is a brush made of natural boar bristles and is widely used in cleaning, polishing, art and other fields. Its structure usually consists of a plate-like base (called a brush body or brush plate), which can be made of wood, plastic or other materials. A large number of boar bristles are evenly distributed in an array on the surface. The bristles are firmly installed on the base by punching, implanting, bonding or fixing with metal clips. The boar bristles have good toughness and wear resistance, are densely arranged, and the ends are soft and powerful. They can effectively remove dust or perform smearing operations without damaging the surface of the object.

[0003] Before a boar bristle brush leaves the factory, its quality stability, wear resistance, and bristle firmness are important indicators for evaluating its product performance. Existing testing methods mostly rely on manual sampling or simple pull-out tests, which are difficult to simulate the repeated friction and wear process in real usage scenarios. The test results are highly subjective, have poor repeatability, and are inefficient. There is also a lack of systematic testing methods for the dynamic contact performance between the bristles and the test medium, especially in terms of bristle wear resistance and hair loss. There is a lack of efficient and stable dynamic friction simulation devices. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following advantages: 1. The main structure of the present invention includes a testing table, a bearing seat, an inverted U-frame and an inverted T-block. The top of the inverted T-block is used to store a boar bristle brush. An I-shaped plate is movably inserted into the bottom of the inverted U-frame. The I-shaped plate is used to wrap the test cloth to be ground. A reciprocating drive assembly is provided on the side of the inverted T-block. The reciprocating drive assembly drives the boar bristle brush on the top of the inverted T-block to rub back and forth with the test cloth to be ground, and uses the reciprocating drive assembly to drive it to rub back and forth with the I-shaped plate covering the test cloth. It can accurately simulate the force and movement state of the brush during actual cleaning or use. This structure makes the detection closer to the actual working conditions and improves the accuracy of the assessment of the wear resistance, firmness and hair loss of the bristles.

[0017] 2. The present invention is provided with a bearing seat, and the inverted T-block is movably inserted into the bearing seat in the horizontal direction, and a lifting assembly is provided at the bottom of the bearing seat. When the lifting assembly is in standby mode, there is a sufficient height difference between the inverted T-block and the I-plate. This height difference provides sufficient operating space for the user to replace or install the test cloth to be polished, avoiding the inconvenience of operation caused by limited space, and improving the efficiency and accuracy of test cloth replacement. Secondly, this structure can effectively avoid unnecessary friction contact between the bristle brush and the test cloth before the equipment is started, which helps to extend the service life of the bristles and the test cloth. In addition, the setting of the lifting assembly can also prevent the inverted T-block from immediately contacting the I-plate when the reciprocating drive assembly is mistakenly started, effectively preventing its instantaneous displacement from causing accidental collision damage to the user's hand, and improving the operational safety of the entire device.

[0018] 3. The lifting assembly in the present invention has multiple functions, which significantly improves the operational convenience, detection stability and structural safety of the device. On the one hand, the lifting assembly can lift the supporting base together with the inverted T-block as a whole after the user completes the installation of the test cloth, so that the bristle brush on the top of the inverted T-block can achieve effective contact with the test piece to be worn on the I-beam, thereby ensuring the accuracy and fit of subsequent friction detection. On the other hand, a lifting folding seat is provided in the lifting assembly, which can reliably limit the I-beam to the side of the inverted U-frame during the lifting process, effectively preventing the I-beam from being displaced due to lateral force during the reciprocating friction process, ensuring that the test cloth is always in a stable and fixed detection position, avoiding detection errors, and integrating the three functions of height adjustment, brush head positioning and test piece limiting in one. It has a compact structure and coordinated movements, which is convenient for user operation and improves the stability and detection repeatability of the whole machine.

[0019] 4. One of the core components of the reciprocating drive assembly of the present invention is the reciprocating stroke adjustment assembly. The reciprocating stroke adjustment assembly controls the reciprocating movement stroke of the inverted T block, thereby controlling the reciprocating friction stroke of the bristle brush to be tested. It can accurately adjust the friction path length between the bristle brush and the test piece, thereby flexibly adapting to the brush detection requirements of different specifications and different application scenarios. In addition, one of the core components of the reciprocating stroke adjustment assembly is the instant power supply assembly. The instant power supply assembly can adjust and control the reciprocating movement stroke of the inverted T block in real time without stopping the reciprocating drive assembly, thereby avoiding time loss and equipment wear caused by frequent start and stop, and ensuring the efficiency of friction quality detection.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0034] Reference Figure 1-11 A quality inspection device for finished bristle brushes includes a testing platform 2, a bearing seat 10 and an inverted T-block 33. An inverted U-frame 1 is fixedly provided on the top of the testing platform 2. An I-plate 8 is movably inserted into the middle position of the side of the inverted U-frame 1. The outer wall of the I-plate 8 is wrapped with the test piece cloth to be rubbed. It should be supplemented that the inverted U-frame 1 is provided with a slot of matching shape at the insertion position of the I-plate 8, and one end of the slot is not aligned with one side of the inverted U-frame 1. Therefore, as long as the other end of the slot is blocked, the I-plate 8 can be limited to the inside of the inverted U-frame 1 so that no displacement occurs. In addition, there is a gap fit between the slot and the I-plate 8, and the gap between the slot and the I-plate 8 is used to accommodate the cloth to be tested wrapped by the I-plate 8.

[0035] The testing platform 2 is provided with a vertical guide column 101 movably inserted under the inverted U-frame 1, a supporting seat 10 is fixedly provided on the top of the vertical guide column 101, an inverted T-block 33 is movably inserted into the supporting seat 10 in the horizontal direction, and a fixing component for fixing the bristle brush to be tested is provided on the top of the inverted T-block 33; The testing platform 2 is provided with a reciprocating drive assembly on one side of the inverted T-block 33. The reciprocating drive assembly is used to drive the bristle brush to reciprocate along a preset direction relative to the test piece cloth to achieve reciprocating friction contact between the bristle brush and the test piece cloth. The reciprocating drive assembly includes a driving disk 9, a driving rod 20, a vertical column 21 and a reciprocating stroke adjustment assembly. The reciprocating stroke adjustment assembly controls the reciprocating movement stroke of the inverted T-block 33. The bottom center position of the driving disk 9 is fixedly connected to the output end of the driving motor 4. The driving motor 4 is fixedly arranged on the top of the motor base 3. The motor base 3 is fixedly arranged at the bottom of the testing platform 2. The vertical column 21 is movably inserted into one end of the driving rod 20. The vertical column 21 is screwed with a locking nut 210 on the upper and lower surfaces of one end of the driving rod 20. The bottom of the vertical column 21 is movably inserted into the top of one end of the inverted T-block 33. Figure 8 The vertical column 21 has a certain length. Therefore, when the inverted T block 33 moves a certain distance in the vertical direction, the driving disk 9 and the driving rod 20 still form a "crank slider structure" to drive the inverted T block 33 to move back and forth a certain distance in the horizontal direction.

[0036] The reciprocating stroke adjustment component includes a micro motor 22, an adjustment screw 23, a drive block 24 and an instant power supply component. The instant power supply component supplies power to the micro motor 22 instantly when the micro motor 22 rotates. An adjustment slot 91 is provided on the top of the drive disk 9. The micro motor 22 is fixedly provided at the end of the adjustment slot 91. The output end of the micro motor 22 is fixedly provided with an adjustment screw 23. The outer wall of the adjustment screw 23 is threaded with a drive block 24. The top of the drive block 24 is rotatably connected to one end of the drive rod 20. Therefore, the relative position of the drive block 24 and the center of the drive disk 9 can be adjusted, thereby controlling the relative position of one end of the drive rod 20 and the center of the drive disk 9.

[0037] The instant power supply assembly includes an inner connecting ring 26, an outer connecting ring 27, and a fixed folding rod 29. The bottom of the micro motor 22 is fixed with a power connection post 25. One end of the fixed folding rod 29 is fixed on the top of the detection table 2. The bottom of the other end of the fixed folding rod 29 is fixed with an inner connecting ring 26 and an outer connecting ring 27 in sequence. The tops of the inner connecting ring 26 and the outer connecting ring 27 are respectively in contact with the power connection post 25 of the micro motor 22. The inner connecting ring 26, the outer connecting ring 27, and the fixed folding rod 29 are arranged below the driving disk 9, and as shown in FIG. Figure 10 As shown, the bottom of the inner connecting ring 26 and the outer connecting ring 27 are provided with terminal posts for connecting to the external power supply system. The side of the fixed folding rod 29 is provided with a wire groove 28 for accommodating the power supply line of the external power supply system to connect to the inner connecting ring 26 and the outer connecting ring 27. The inner connecting ring 26 and the outer connecting ring 27 are concentrically arranged. When the driving disk 9 drives the micro motor 22 to rotate, the two connecting posts 25 of the micro motor 22 are always in contact with the inner connecting ring 26 and the outer connecting ring 27.

[0038] The inverted U-frame 1 is provided with a lifting assembly on one side of the supporting seat 10. The lifting assembly drives the bristle brush on the top of the supporting seat 10 to move up to the bottom position of the test piece cloth, and at the same time limits the I-plate 8 to the side of the inverted U-frame 1. The rear side of the inverted U-frame 1 is provided with an auxiliary holding assembly. When the lifting assembly fails, the auxiliary holding assembly keeps the bristle brush at a certain height and in contact with the test piece cloth.

[0039] The lifting assembly includes a lifting cylinder 5 and a lifting folding seat 6. The lifting folding seat 6 includes a vertical section and a horizontal section. The lifting cylinder 5 is fixed at the bottom of the testing table 2. The output end of the lifting cylinder 5 is vertically upward. The output end of the lifting cylinder 5 is fixed with a lifting folding seat 6. The lifting folding seat 6 includes a horizontal section and a vertical section. The horizontal section of the lifting folding seat 6 extends into the bottom of the bearing seat 10, and the vertical section of the lifting folding seat 6 fits into the side of the inverted U frame 1.

[0040] The fixing assembly includes a vertical screw 32, a locking pressure handle 31 and a holding rod 34. A contoured groove 30 is provided on the top of the inverted T-block 33. The shape of the contoured groove 30 is the same as the appearance of an actual boar bristle brush, including a cylindrical cavity and a rectangular cavity. The cylindrical cavity is used to accommodate the head of the boar bristle brush, and the rectangular cavity is used to accommodate the handle of the boar bristle brush. A vertical screw 32 is symmetrically fixed on one side of the contoured groove 30 at the top of the inverted T-block 33. The head of the vertical screw 32 is provided with an external thread. A holding rod 34 is movably inserted into the outer wall of the vertical screw 32. The locking pressure handle 31 is screwed into the head of the vertical screw 32. The length of the holding rod 34 is not less than the width of the contoured groove 30.

[0041] The auxiliary holding assembly includes a lifting block 13, a fixed seat 14, an attraction electromagnet 19, and a transverse folding plate 7. A transverse movement groove 12 is provided on the top of the transverse folding plate 7. A guide cross column 18 is fixedly provided on the side of the transverse movement groove 12. A guide block 11 is movably inserted into the outer wall of the guide cross column 18. The guide block 11 is fixedly set on the top of the inverted U frame 1. A fixed seat 14 is fixed on the side of the transverse folding plate 7. A right-angle folding rod 15 is movably inserted into the side of the fixed seat 14. A lifting block 13 is rotatably provided at one end of the right-angle folding rod 15. A retaining notch 61 is provided on the side of the vertical section of the lifting folding seat 6. The lifting block 13 is the same width as the retaining notch 61.

[0042] The right-angle folding rod 15 includes a horizontal section and a vertical section. The transverse folding plate 7 is fixedly provided with a retaining frame 16 under the fixed seat 14. The width of the vertical section of the right-angle folding rod 15 is the same as the inner cavity width of the retaining frame 16. The side of the guide block 11 is fixedly connected to one end of the driving spring 17. The other end of the driving spring 17 is fixedly set on the side of the transverse displacement groove 12. The attraction electromagnet 19 is fixedly set on the top of the inverted U frame 1. The output end of the attraction electromagnet 19 faces the side of the transverse folding plate 7. The attraction electromagnet 19 is connected in series to the circuit of the lifting cylinder 5. When the lifting cylinder 5 fails to lose power, the attraction electromagnet 19 is de-energized. When the lifting cylinder 5 is energized, the attraction electromagnet 19 will be energized to attract the transverse folding plate 7 away from the side of the lifting folding seat 6. At this time, the driving spring 17 is compressed.

[0043] The specific implementation steps and principles of the present invention are as follows: In the initial state, the lifting cylinder 5 is in the retracted state. At this time, the supporting base 10 is at the lowest position on the top of the testing platform 2. The vertical section of the supporting base 10 does not block the side of the inverted U-frame 1. On the one hand, the user puts the I-shaped plate 8 on the cloth to be tested, and then inserts the I-shaped plate 8 into the corresponding slot on the side of the inverted U-frame 1.

[0044] On the other hand, loosen the two locking pressure handles 31, rotate the two holding rods 34 away from the top of the profiling groove 30, then place the bristles of the bristle brush to be tested vertically upward, and finally rotate the two holding rods 34 to the top of the profiling groove 30. Since the existing bristle brush is generally provided with a handle, the two holding rods 34 hold the handle position of the bristle brush.

[0045] The micro motor 22 starts and drives the adjusting screw 23 to rotate, driving the driving block 24 to continuously approach the appropriate position of the center of the driving disk 9, starting the lifting cylinder 5, and the lifting cylinder 5 drives the lifting folding seat 6 to move vertically upward. On the one hand, the vertical section of the lifting folding seat 6 is fitted to the side of the inverted U frame 1, and the I-plate 8 is limited inside the inverted U frame 1. At the same time, the horizontal section of the lifting folding seat 6 lifts the bearing seat 10 to a certain height. At this time, the boar bristle brush can contact the test cloth at the bottom of the I-plate 8. At this time, the attraction electromagnet 19 is continuously energized, attracting the horizontal folding plate 7 to move horizontally to the extreme position. At this time, even if the user moves the right-angle folding rod 15 horizontally to the extreme position, it will not drive the lifting block 13 to move to the vertical displacement path of the lifting folding seat 6, thereby hindering the displacement of the lifting folding seat 6.

[0046] At this time, the driving motor 4 is started, and the driving motor 4 drives the bristle brush on the top of the inverted T block 33 to continuously reciprocate and rub against the cloth to be tested through the driving disk 9 and the driving rod 20.

[0047] Assuming that the lifting cylinder 5 fails and cannot continue to lift the folding seat 6 at a specific height, the attraction electromagnet 19 connected in series with the lifting cylinder 5 is powered off, and the horizontal folding plate 7 is reset due to the driving spring 17. At this time, the folding seat 6 is lifted up by manpower, and finally the lifting block 13 at one end of the right-angle folding rod 15 is inserted into the retaining notch 61 to maintain the folding seat 6 at a specific height.

[0048] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
