Abstract
Description
Technical Field
[0001] This invention relates to the field of furniture paint film testing equipment, specifically an integrated tooling for multi-item testing of furniture surface paint film. Background Technology
[0002] When integrating multi-item testing of furniture surface coatings, four core testing items are required: coating adhesion (4893.4), abrasion resistance (4893.7), impact resistance (4893.9), and resistance to temperature differences (4893.6). This method is compatible with coating samples from different substrates such as solid wood furniture and engineered wood furniture.
[0003] The existing GB / T4893 series tests require the use of four independent sets of fixtures: the fixture for adhesion testing cannot fix the impact test sample, the abrasion resistance test requires separate adjustment of the grinding head pressure, and the sample is easily contaminated or bumped when transferred between different fixtures, resulting in low testing efficiency. At the same time, traditional fixtures have poor stability in fixing irregularly shaped paint film samples (such as curved cabinet door panels and sloping tabletops), which cannot meet the standard requirement of "flat and displacement-free test surface", affecting the accuracy of test data. Summary of the Invention
[0004] The purpose of this invention is to provide an integrated tooling for multi-item testing of paint film on furniture surfaces, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated fixture for multi-item testing of furniture surface paint film, comprising a main frame and a sanding component. A fixed platform is provided on one side of the bottom of the main frame, and a heating plate is installed inside the fixed platform. Negative pressure suction holes are equidistantly opened inside the fixed platform. A horizontal plate is installed above the fixed platform, and an adhesion testing component for adhesion testing is slidably arranged in the middle of the horizontal plate. The adhesion testing component includes a slider, an electric push rod three, a connecting plate, and a cross-cutting knife. An electric push rod three is provided at the bottom of the slider, and a connecting plate is installed at the output end of the electric push rod three. A cross-cutting knife is provided at the bottom of the connecting plate. An impact component for impact testing is provided on one side of the horizontal plate, and the impact component includes an electric push rod one and an impact element. An impact element is installed at the output end of the electric push rod one. The sanding component for sanding testing is located on the side close to the impact component.
[0006] Furthermore, the impact assembly also includes a slider seat, a mounting plate, and a graduated impact outer cylinder. The graduated impact outer cylinder is provided on the outside of the electric push rod, and the top of the graduated impact outer cylinder is provided with a mounting plate. The slider seat is fixedly mounted on the outer surface of the mounting plate by bolts.
[0007] Further, the slider base is slidably arranged inside the cross plate. The grinding component includes an electric push rod II, a mounting plate, a grinding motor and a grinding head. The output end of the electric push rod II is provided with the mounting plate. The bottom of the mounting plate is provided with the grinding motor, and the output end of the grinding motor is provided with the grinding head.
[0008] Further, the slider is slidably arranged inside the cross plate, and the cross section of the slider is distributed in a "T" shape.
[0009] Further, one end of the negative pressure suction hole is communicated with a suction hole connecting pipe, and a rubber pad is installed on the outer surface of the main body frame.
[0010] Further, a limiting component for auxiliary fixation is arranged on one side of the top of the cross plate. The limiting component includes an electric push rod IV and a collecting plate. The output end of the electric push rod IV is provided with the collecting plate.
[0011] Further, the limiting component further includes a pressing strip I, a pressing strip II and a silica gel pad. The bottom of the collecting plate is provided with the pressing strip I. The end of the pressing strip I is provided with the pressing strip II. The outer surfaces of the bottoms of the pressing strip I and the pressing strip II are provided with the silica gel pad.
[0012] Further, the pressing strip I and the pressing strip II form a "C" shaped structure, and there are two groups of pressing strip I.
[0013] The present invention provides an integrated tooling for multi-item detection of furniture surface paint films, and has the following beneficial effects: 1. The present invention integrates four core functions of pre-treatment of resistance to cold and heat temperature difference, adhesion detection, abrasion resistance detection, and impact resistance detection. Through the adhesion detection component, impact component and grinding component slidably arranged on the cross plate, in-situ continuous detection of the same sample on the fixing table can be realized, without multiple sample transfers and re-clamping. Compared with traditional split-type detection equipment, the time for a single sample to complete four detections is greatly shortened, effectively reducing the labor and time costs in the detection process.
[0014] 2. The present invention, through the fixing table of this tooling in combination with the negative pressure suction holes, makes the fixing table a honeycomb-shaped vacuum adsorption panel. The negative pressure suction holes and the suction hole connecting pipes form a fixed structure with adjustable adsorption force. The suction hole connecting pipes are connected to the vacuum pump. At the same time, in combination with the "C" shaped pressing strip I, pressing strip II and the bottom silica gel pad of the limiting component, furniture paint film samples in various forms such as flat surface, arc surface, and inclined surface can be stably fixed.

A fixed platform 3 is provided on one side of the bottom of the main frame 1, and a heating plate 4 is installed inside the fixed platform 3. By opening the heating plate 4 inside the fixed platform 3 and using the pre-set temperature sensor in the heating plate 4, the temperature is monitored. During pretreatment, the sample remains in an adsorption and fixed state without the need for sample transfer. Negative pressure suction holes 5 are equidistantly spaced inside the fixed platform 3, with one end of each hole connected to a suction hole connecting pipe 6.

Pushing the T-shaped slider 901 of the adhesion testing component 9, it slides along the horizontal plate 2 to directly above the sample testing area. The height of the cross-section cutter 904 is adjusted using the electric push rod 902, setting the cross-section depth to 1mm, ensuring that the perpendicularity error between the cross-section cutter and the sample surface is ≤0.1°, after completing the scribing operation along a fixed trajectory, use the tape peeling auxiliary clip to stick the tape and peel it off at a uniform speed, observe the paint film peeling and record the data. The output end of the electric push rod 902 is equipped with a connecting plate 903, and the bottom of the connecting plate 903 is equipped with a scribing blade 904. One side of the horizontal plate 2 is equipped with an impact assembly 7 for impact testing, and the impact assembly 7 includes an electric push rod 704 and an impact element 705. The output end of the electric push rod 704 is equipped with the impact element 705. The grinding assembly 8 for grinding testing is located on the side close to the impact assembly 7.

The slider seat 701 is fixedly installed on the outer surface of the mounting plate 702 by bolts. The slider seat 701 of the sliding impact assembly 7 is... 01. Move the grinding assembly 8 to the side of the horizontal plate 2 to avoid the sample. Then move the grinding assembly 8 to the testing area. Adjust the height of the mounting plate 802 using the electric push rod 801 so that the grinding head 804 is in contact with the sample surface for wear resistance testing. Move the grinding assembly 8 to the avoidance position and slide the impact assembly 7 to the testing area. Adjust the impact height to 300mm corresponding to an impact energy of 1.5J using the scaled impact outer cylinder 703. Control the electric push rod 704 to drive the impact component 705 to fall along the guide cylinder to impact the sample surface. Observe whether the paint film cracks or peels off to complete the standard impact resistance test. The slider seat 701 is slidably set inside the horizontal plate 2. The grinding assembly 8 includes the electric push rod 801, the mounting plate 802, the grinding motor 803, and the grinding head 804. The output end of the electric push rod 801 is equipped with the mounting plate 802, the bottom of the mounting plate 802 is equipped with the grinding motor 803, and the output end of the grinding motor 803 is equipped with the grinding head 804.
[0019] like Figure 5As shown in the figure, a limiting component 11 for auxiliary fixation is provided on one side of the top of the horizontal plate 2. The limiting component 11 includes an electric push rod four 1101 and a collection plate 1102. The output end of the electric push rod four 1101 is equipped with a collection plate 1102. The limiting component 11 further includes a first pressing strip 1103, a second pressing strip 1104 and a silica gel pad 1105.

The bottom outer surfaces of the first pressing strip 1103 and the second pressing strip 1104 are provided with a silica gel pad 1105. The first pressing strip 1103 and the second pressing strip 1104 form a "C" - shaped structure, and there are two groups of the first pressing strips 1103. Place the solid wood door panel paint film sample stably on the honeycomb - shaped vacuum adsorption panel of the fixing table 3, ensure that the sample surface completely covers the negative pressure suction hole 5 area, start the vacuum pump, adjust the adsorption force to 60 kPa through the suction hole connecting pipe 6, and at the same time control the electric push rod four 1101 of the limiting component 11 to extend, driving the collection plate 1102 to move downwards, so that the silica gel pads 1105 at the bottoms of the "C" - shaped first pressing strip 1103 and the second pressing strip 1104 are fitted to the edge of the sample, and double fixation avoids displacement during the detection process.
[0020] In summary, for this integrated tooling for multi - item detection of the paint film on the furniture surface, first, according to Figures 1-5In the structure shown, during use, after placing the sample to be detected on the honeycomb vacuum adsorption panel of the fixed table 3, connect the vacuum pump through the suction hole connecting tube 6, so that the negative pressure suction hole 5 generates an adjustable adsorption force of 0 - 100 kPa to tightly adsorb the sample surface. At the same time, the limiting component 11 on the cross plate 2 drives the assembly plate 1102 to move down through the electric push rod four 1101,带动 the "C"-shaped pressing strip one 1103 and the pressing strip two 1104 to fit the edge of the sample. The bottom silicone pad 1105 buffers the pressure and increases the friction force, adapting to various shaped samples such as flat, arc-shaped, and inclined plane. Each detection component is adapted to the cross plate 2 by sliding to achieve rapid switching of the detection position. The adhesion detection component 9 slides along the internal chute of the cross plate 2 by means of the T-shaped slider 901, and precisely adjusts the depth and perpendicularity of the scribing knife 904 through the electric push rod three 902 to complete the scribing and tape peeling detection. The polishing component 8 is driven to slide by the slider seat 701, adjusts the height of the polishing head 804 through the electric push rod two 801, and配合 the polishing motor 803 to achieve a wear resistance test with a pressure switch of 500 g / 1000 g. The impact component 7 is also slid and positioned through the slider seat 701, adjusts the impact height of 100 - 500 mm by using the graduated impact outer cylinder 703, and drives the impact piece 705 to complete the impact resistance detection of energy through the electric push rod one 704. The impact piece 705 includes an impact drill and a drill bit. The three major components can quickly switch the detection station without disassembly. The fixed table 3 is internally provided with a heating plate 4 and a temperature sensor inside for monitoring the temperature. During the pretreatment process, the sample remains in a fixed state and can directly enter the subsequent detection without transfer. The rubber pad 10 on the outer surface of the main frame 1 plays a role in shock absorption and buffering, reducing the influence of equipment vibration on data accuracy during the detection process, and ensuring that各项检测 meet the requirements of the GB / T4893 series standards.
