Description

Technical Field

[0001] This utility model relates to the field of rubber sample preparation technology, specifically to a test laboratory rubber sample preparation device. Background Technology

[0002] Rubber specimens are samples used to test the properties of rubber. These specimens are usually prepared according to specific specifications in order to accurately evaluate the physical and mechanical properties of rubber.

[0003] In existing technologies, rubber sample preparation involves three steps: first, thickness adjustment and cutting into several thin slices; second, fine grinding of the slices using a grinding machine; and third, cutting to form the sample. All of these processes are manual, which is not only inefficient and labor-intensive but also prone to resulting in irregular sample cuts, affecting testing efficiency and failing to meet the requirements of high efficiency and low cost in testing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention proposes a laboratory rubber sample preparation device that can improve the efficiency and accuracy of sample preparation.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a test laboratory rubber sample preparation device, comprising a slicing mechanism, a grinding mechanism, and a punching mechanism;

[0006] The slicing mechanism includes an upper telescopic arm, a lower telescopic arm, and a slicing blade. The upper and lower telescopic arms are arranged opposite to each other, with their ends that are far apart from each other fixedly arranged, and their ends that are close to each other each provided with a negative pressure adsorber. The slicing blade is rotatably arranged and can move toward the upper and lower telescopic arms.

[0007] The grinding mechanism includes a conveyor belt and a grinding wheel, the lower telescopic arm is located at one end of the conveyor belt, and the grinding wheel is rotatably located above the conveyor belt;

[0008] The punching mechanism includes a pad and a cutter. The pad is located at the other end of the conveyor belt, and the cutter is vertically and vertically positioned above the pad.

[0009] First, the sample is placed on the lower telescopic arm and fixed in place by the negative pressure adsorber. Then, the upper telescopic arm extends towards the lower telescopic arm, contacting the sample and further fixing it in place by the negative pressure adsorber. Next, the slicing blade is activated and moves towards the sample, cutting the lower part of the sample to the desired thickness. The lower telescopic arm then shortens downwards until the sample contacts the conveyor belt. At this point, the negative pressure adsorber on the lower telescopic arm is closed, and the sample is transported to the grinding wheel by the conveyor belt. The grinding wheel rotates and polishes the sample. After polishing, the conveyor belt continues to transport the sample to the pad, and the cutter descends to cut the sample into the desired shape, thus completing the sample preparation.

[0010] The beneficial effects of the above-mentioned testing laboratory rubber sample preparation device are: compared with manual slicing, grinding and cutting, it improves processing efficiency, accuracy and yield.

[0011] Furthermore, the slicing mechanism also includes a motor, which is mounted on the frame and connected to the slicing blade, and is capable of driving the slicing blade to rotate. The slicing blade is a circular slicing blade.

[0012] The sample can be cut by rotating the slicing blade at high speed driven by a motor. The circular slicing blade cuts the sample through one half, which avoids interference while maintaining contact with the sample.

[0013] Furthermore, the slicing mechanism also includes a slide rail and a cylinder, both of which are mounted on the frame. The motor is movably mounted on the slide rail, and the cylinder is connected to the motor, enabling it to drive the motor to move on the slide rail.

[0014] The cylinder drives the motor to move, which in turn moves the slicing blade toward the sample, thereby gradually cutting the sample to the required thickness.

[0015] Furthermore, the grinding wheel mechanism also includes a second motor, which is connected to the grinding wheel and can drive the grinding wheel to rotate.

[0016] The second motor drives the grinding wheel to rotate, which can polish the surface of the sample to improve the accuracy of the sample thickness.

[0017] Furthermore, the grinding disc mechanism also includes a vertically arranged slide rail two, and the motor two is movably arranged on the slide rail two and connected to a cylinder two, which can drive the motor two to move on the slide rail two.

[0018] Depending on the required thickness of the sample, the grinding wheel can be adjusted to contact the sample surface by driving the motor to rise or fall via the cylinder.

[0019] Furthermore, the pad is movably mounted on the slide rail three, and the pad is connected to a cylinder three, which can drive the pad to move on the slide rail three.

[0020] After the conveyor belt transfers the sample to the pad, cylinder three drives the pad to move on slide rail three, so that the cutting blade can be aligned with the cutting blade to complete the cutting. The punching point is set at a position away from the conveyor belt to avoid interference.

[0021] Furthermore, the punching mechanism also includes a press, which is connected to the cutting blade and can drive the cutting blade to rise and fall.

[0022] The press can drive the cutting blade to rise and fall, cutting the sample into the desired shape. Attached Figure Description

[0030] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0031] Please see Figure 1 and Figure 2 This utility model provides a test laboratory rubber sample preparation device, including a slicing mechanism 10, a grinding mechanism 20 and a punching mechanism 30, which can sequentially slice, grind and cut the sample.

[0032] Specifically, the slicing mechanism 10 includes an upper telescopic arm 11, a lower telescopic arm 12, and a slicing blade 13. The upper telescopic arm 11 and the lower telescopic arm 12 are both arranged vertically and opposite to each other, with their ends fixed away from each other and negative pressure suction devices provided at their ends close to each other. The slicing blade 13 is rotatably mounted and can move towards the upper telescopic arm 11 and the lower telescopic arm 12. The grinding mechanism 20 includes a conveyor belt 21 and a grinding wheel 22. The lower telescopic arm 12 is located at one end of the conveyor belt 21, and the grinding wheel 22 is rotatably mounted above the conveyor belt 21. The punching mechanism 30 includes a pad 31 and a cutting blade 32. The pad 31 is located at the other end of the conveyor belt 21, and the cutting blade 32 is vertically mounted above the pad 31.

[0033] First, the sample is placed on the lower telescopic arm 12 and fixed by the negative pressure adsorber. Then, the upper telescopic arm 11 extends towards the lower telescopic arm 12 and, upon contact with the sample, is also fixed by the negative pressure adsorber. The slicing blade 13 is activated and moves towards the sample. The extension and retraction of the upper telescopic arm 11 and the lower telescopic arm 12 can adjust the height of the sample, thereby adjusting the cutting thickness. After the lower part of the sample is cut to the desired thickness, the lower telescopic arm 12 retracts downward until the sample contacts the conveyor belt 21. At this point, the negative pressure adsorber of the lower telescopic arm 12 is closed and the conveyor belt 21 is turned on, which transports the sample to the grinding wheel 22. The grinding wheel 22 is then activated to grind the sample. After grinding, the conveyor belt 21 continues to transport the sample to the pad 31, and the cutter 32 descends to cut the sample into the desired shape, thus completing the sample preparation.

[0034] Specifically, the slicing mechanism 10 also includes a motor 14, a slide rail 15, and a cylinder 16. Both the slide rail 15 and the cylinder 16 are mounted on the frame. The motor 14 is movably mounted on the slide rail 15 and connected to the slicing blade 13, enabling it to drive the slicing blade 13 to rotate. The slicing blade 13 is a circular cutter. The cylinder 16 is connected to the motor 14 and enables it to drive the motor 14 to move on the slide rail 15.

[0035] The starter motor 14 drives the slicing blade 13 to rotate at high speed, which can cut the sample. The cylinder 16 drives the motor 14 to move, and the slicing blade 13 moves towards the sample to cut the sample to the required thickness. The circular slicing blade 13 cuts the sample through one half, which can avoid interference and maintain contact with the sample.

[0036] Specifically, the grinding wheel mechanism 20 also includes a second motor 23 and a second slide rail 24. The second motor 23 is connected to the grinding wheel 22 and can drive the grinding wheel 22 to rotate. The second slide rail 24 is vertically arranged, and the second motor 23 is movably arranged on the second slide rail 24 and connected to a second cylinder 25. The second cylinder 25 can drive the second motor 23 to move on the second slide rail 24.

[0037] Depending on the required thickness of the sample, the cylinder 25 drives the motor 23 to rise or fall, adjusting the position so that the grinding wheel 22 can contact the sample surface. By rotating the grinding wheel 22 with the motor 23, the surface of the sample can be polished to improve the accuracy of the sample thickness.

[0038] Specifically, the punching mechanism 30 also includes a press 33, which is connected to the cutter 32 and can drive the cutter 32 to rise and fall. The pad 31 is movably mounted on the slide rail 34, and the pad 31 is connected to a cylinder 35, which can drive the pad 31 to move on the slide rail 34.

[0039] The press 33 can drive the cutter 32 to rise and fall, cutting the sample into the required shape. After the conveyor belt 21 conveys the sample to the pad 31, the cylinder 35 drives the pad 31 to move on the slide rail 34, so that the cutter 32 can be aligned to complete the cutting. Setting the punching point at a distance from the conveyor belt 21 can avoid interference.

[0040] The working principle of the aforementioned laboratory rubber sample preparation device is as follows: During processing, the sample is first placed on the lower telescopic arm 12 and fixed by a negative pressure adsorber. Then, the upper telescopic arm 11 extends downward and, after contacting the sample, is also fixed by a negative pressure adsorber. The motor 14 is started to drive the slicing blade 13 to rotate, and the cylinder 16 pushes the motor 14 to move the slicing blade 13 toward the sample. The extension and retraction of the upper telescopic arm 11 and the lower telescopic arm 12 can adjust the height of the sample, thereby adjusting the cutting thickness of the sample. The height difference between the bottom surface of the sample and the slicing blade 13 is the slice thickness of the sample.

[0041] After slicing, the lower telescopic arm 12 retracts until the sample contacts the conveyor belt 21. The negative pressure adsorber is turned off and the conveyor belt 21 is turned on, which can transport the sample to the grinding wheel 22. The motor 23 is started to drive the grinding wheel 22 to rotate and grind the sample. The cylinder 25 can adjust the height of the grinding wheel 22.

[0042] After grinding, the conveyor belt 21 continues to transport the sample to the pad 31. The cylinder 35 drives the pad 31 to move below the cutter 32. The press 33 drives the cutter 32 to descend and cut the sample into the required shape, thus completing the sample preparation.

[0043] Using the aforementioned laboratory rubber sample preparation device, automatic slicing, grinding, and cutting are achieved, which not only improves the efficiency of processing and preparation but also enhances the accuracy and yield of processing.

[0044] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
