Description

Technical Field

[0001] This utility model relates to the technical field of coating mold production test equipment, and in particular to a test device for wheel-type coating abrasives. Background Technology

[0002] In modern industrial production, wheel-type coated abrasives, with their unique grinding performance, are used in the machining field for surface polishing of precision parts to improve surface smoothness; in the automotive manufacturing industry for polishing body parts to ensure appearance quality; and in the furniture production process for fine processing of wood surfaces to make them smooth to the touch.

[0003] With the increasing application scenarios of wheel-type coated abrasives, the market demand for customization is growing, and existing mass-produced products cannot efficiently and quickly meet these needs. On the one hand, traditional mass production lines have high production costs and make it difficult to fully verify the production process in the early stages; on the other hand, the market lacks testing devices that can accurately simulate actual production conditions, making it impossible to effectively assess the impact of different process parameters on product performance. This leads to performance instability issues such as abrasive grain shedding and low grinding efficiency in actual use, seriously hindering the development of the industry and product upgrades. Utility Model Content

[0004] The purpose of this invention is to solve the problems of customized production requirements and unstable quality and performance of existing wheel-type coated abrasives. It provides a testing device for wheel-type coated abrasives that can systematically simulate the production process, realize precise testing and control of customized products, and thus improve product quality and production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A test apparatus for wheel-type coated abrasives includes a raw material unwinding mechanism, an adhesive coating mechanism, and a winding mechanism that cooperate with each other.

[0007] The raw material unwinding mechanism includes an unwinding device, which has an unwinding motor inside;

[0008] The coating mechanism includes a pair of transition rolls. The raw material is received and transferred from the outer ring of the unwinding device to the transition rolls. A pair of coating rollers are provided on the lower side of the transition rolls. A gap adjustment device is provided between the coating rollers. An adhesive coating nozzle is also provided above the coating rollers. The adhesive coating nozzle is connected to the adhesive storage tank through a pressure pump. A second transition roll is also provided on one side of the coating rollers.

[0009] The winding mechanism includes a transition roll three located at the top of the frame. A winding motor is installed on the frame, and the output end of the winding motor is connected to a winding shaft. The coated material passes through the gap between the coating rollers and is received on the winding shaft via the transition roll two and the transition roll three. A pressing device is located directly above the winding shaft, and a sensor is installed inside the pressing device.

[0010] Furthermore, the unwinding motor is a variable frequency speed control motor with an unwinding speed of 0~15m / min, which is used to ensure that the nylon cloth is smoothly and uniformly conveyed to the coating process by steplessly adjusting the unwinding speed, so as to provide a stable raw material input for subsequent operations.

[0011] Furthermore, the base material of the raw material unwinding mechanism is nylon fiber cloth, and the thickness of the nylon fiber cloth is set to 1~30mm.

[0012] Furthermore, the transition roll is connected to both sides of the transition platform. The transition roll on the side closer to the raw material unwinding mechanism is engaged with the unwinding device, and the transition roll on the other side is engaged with the coating roller. The transition platform is placed horizontally, and the transition rolls on both sides are on the same horizontal line.

[0013] Furthermore, the coating roller includes a left coating roller and a right coating roller, which are on the same horizontal line. The rotating shafts of the left and right coating rollers are connected to the gap adjustment device. The gap adjustment device includes a slider and a lead screw that cooperate with each other. One end of the lead screw is provided with a rotating handle for rotating the handle to adjust the gap between the coating rollers.

[0014] Furthermore, the adhesive coating nozzle is positioned directly above the right coating roller, and its coating rate is 0.1~2 kg / min, so as to evenly coat the prepared adhesive onto the surface of the nylon cloth.

[0015] Furthermore, the gap adjustment device has an adjustment gap range of 0.05~5mm, which is used to accurately squeeze out excess adhesive based on the viscosity, solid content and target coating amount of the adhesive.

[0016] Furthermore, the winding shaft is fixed to the frame by bearings, a tension sensor is provided on one side of the winding shaft, the winding motor is a servo motor, and the tension on the winding shaft is maintained within a set value of ±1N, so as to monitor and control the winding tension in real time.

[0017] Furthermore, the clamping device is an electric lifting structure, and the built-in sensors include a displacement sensor and a pressure sensor, with an adjustment accuracy of 0.1mm, so as to automatically control the clamping device to perform adaptive distance lifting based on the preset pressure value and displacement change.

[0018] Furthermore, the pressing device includes a lifting mechanism connected to the frame, with a pressing wheel connected to the bottom of the lifting mechanism. The axis of the pressing wheel and the axis of the winding shaft are both located on the vertical axis of the lifting mechanism.

[0019] Compared with the prior art, the advantages of the technical solution of this utility model are as follows:

[0020] (1) The unwinding mechanism of this utility model adopts stepless adjustment of unwinding speed, which ensures that the nylon cloth is transported to the coating process smoothly and at a uniform speed, providing a stable raw material input for subsequent operations;

[0021] (2) The device of this utility model can not only evenly apply the prepared glue to the surface of the nylon cloth, but also precisely adjust the gap of the glue coating roller, and precisely squeeze out the excess glue according to the viscosity, solid content and target amount of glue, so as to ensure product quality.

[0022] (3) This utility model uses a special high-temperature resistant and high-viscosity adhesive tape to firmly fix the semi-finished product coated with mortar onto the winding shaft. It also uses a combination of a high-precision tension sensor and a closed-loop control system to monitor the winding tension in real time, which effectively ensures the uniformity of the product winding and avoids uneven tension.

[0023] (4) This utility model achieves precise testing and control of customized products by systematically simulating the production process, thereby improving product quality and production efficiency. Attached Figure Description

The specific embodiments described herein are for illustrative purposes only and are not intended to limit this utility model.

[0027] See Figure 1 A test apparatus for wheel-type coated abrasives, comprising a raw material unwinding mechanism 1, a coating mechanism 2, and a winding mechanism 3 that cooperate with each other, characterized in that:

[0028] The raw material unwinding mechanism 1 includes an unwinding device 11, which has an unwinding motor 12 inside it;

[0029] The glue coating mechanism 2 includes a pair of transition rolls 21, which are respectively connected to the two sides of the transition platform 28. The transition roll 21 on the side closer to the raw material unwinding mechanism 1 is engaged with the unwinding device 11, and the transition roll 21 on the other side is engaged with the glue coating roller 22. The transition platform 28 is placed horizontally, and the transition rolls 21 on both sides are on the same horizontal line.

[0030] The raw material is received and transferred from the outer ring of the unwinding device 11 to the transition roll 21. The coating roller 22 includes a left coating roller 22a and a right coating roller 22b, which are on the same horizontal line. The rotating shafts of the left and right coating rollers are connected to the gap adjustment device 23. The gap adjustment device 23 includes a slider and a lead screw that cooperate with each other. One end of the lead screw is provided with a rotating handle 231.

[0031] Above the glue coating roller 22 is a glue coating nozzle 24, which is connected to the glue storage tank 26 via a pressure pump 25. A transition roller 27 is also provided on one side of the glue coating roller 22.

[0032] The winding mechanism 3 includes a transition roll 32 located at the top of the frame 31. A take-up motor 33 is provided on the frame 31. The output end of the take-up motor 33 is connected to a winding shaft 34. The winding shaft 34 is fixed to the frame 31 by bearings. A tension sensor 36 is provided on one side of the winding shaft 34. The coated raw material passes through the glue rollers 22 and is received on the winding shaft 34 via the transition roll 27 and the transition roll 32.

[0033] A clamping device 35 is provided directly above the winding shaft 34. The clamping device 35 is an electric lifting structure. The built-in sensor 35a includes a displacement sensor and a pressure sensor. The clamping device 35 includes a lifting mechanism 35b connected to the frame 31. The bottom of the lifting mechanism 35b is connected to a clamping wheel 35c. The axis of the clamping wheel 35c and the axis of the winding shaft 34 are both on the vertical axis of the lifting mechanism 35b.

[0034] In this embodiment, a specially shaped nylon fiber cloth is selected as the base material, and the thickness of the nylon fiber cloth is precisely set to 1~30mm. The raw material unwinding device 1 is equipped with a variable frequency speed control motor, which can steplessly adjust the unwinding speed within the speed range of 0~15m / min according to the requirements of subsequent processes, ensuring that the nylon cloth is transported smoothly and at a uniform speed to the coating process, providing a stable raw material input for subsequent operations.

[0035] In this embodiment, a high-precision adhesive application nozzle 24 is configured above the adhesive application roller 22. This nozzle is connected to the adhesive storage tank 26 via a pressure pump 25, and applies the prepared adhesive evenly to the nylon fabric surface at a application rate of 0.1~2 kg / min. Next, a pair of rubber extrusion rollers begin operation. A high-precision gap adjustment device 23 is provided between the two rollers, which can precisely adjust the gap within the range of 0.05~5 mm, accurately extruding excess adhesive based on the viscosity, solid content, and target application amount of the adhesive.

[0036] In this embodiment, at the beginning of the winding process, a specially designed high-temperature resistant, high-adhesion tape is used to firmly fix the semi-finished product coated with mortar onto the winding shaft 34. During the winding process, a high-precision tension sensor 36 is combined with a closed-loop control system to monitor the winding tension in real time, and the winding speed is automatically adjusted by a servo motor to ensure that the tension remains stable within ±1N of the set value. Simultaneously, the clamping device 35 adopts an electric lifting structure with built-in displacement and pressure sensors. With each additional turn of winding, the system automatically controls the clamping device to adaptively raise the distance based on the preset pressure value and displacement change. Manual distance adjustment is also possible via buttons on the operation panel, with an adjustment accuracy of up to 0.1mm, effectively ensuring the uniformity of the product winding and preventing uneven tension.

[0037] After the winding process, high-strength hemp thread is used to tightly wrap the wound product with a winding tension of 0-100N to prevent loosening during subsequent handling and drying processes, ensuring the stability of the product structure. Then, a programmed temperature rise drying process is performed at 110-200℃. The dried product is then cut in the width direction to meet diverse market demands.

[0038] The device of this invention is used to simulate and optimize the production process of wheel-type coated abrasives. By systematically simulating the production process, it enables precise testing and control of customized products, thereby improving product quality and production efficiency.

[0039] In addition to the embodiments described above, this utility model may have other implementations. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
