Description

Technical Field

[0001] The utility model relates to the technical field of abrasive cloth processing equipment, in particular to an abrasive cloth unwinding device. Background Art

[0002] Emery cloth is a composite material made of silicon carbide, aluminum oxide and cotton fiber. It has excellent properties such as good wear resistance, high temperature resistance and strength. It is widely used in metal surface grinding, polishing and electronic chip preparation. The processing procedures of emery cloth are mainly divided into emery cloth preparation, emery cloth shaping and emery cloth packaging. Emery cloth preparation is to add the mixed raw materials into the emery cloth machine, tear the raw materials into filaments by high-speed rotation, and then attach the abrasive to the base cloth made of cotton fiber mixture through multiple processes such as heating and pressing, so as to prepare tough and wear-resistant emery cloth material, and then wind the prepared emery cloth material onto the branch pipe, and finally form an emery cloth roll that is convenient for storage, so as to facilitate the collection of the prepared emery cloth material. Emery cloth shaping is to process the prepared emery cloth into emery cloth products of different specifications through multiple processes such as slitting, belt making, cutting, grinding wheel products, etc. Abrasive cloth packaging is to classify the processed abrasive cloth products according to specifications and uses, and use different packaging methods such as paper trays, pallets, tapes, etc. to package and seal them to ensure product quality and transportation safety.

[0003] For the shaping of emery cloth, it is necessary to first unwind the emery cloth roll so that the emery cloth roll can be continuously transported to the shaping machine for product making. In order to ensure that the wound emery cloth material is smoothly transported to the shaping machine for product making, it is necessary to raise the placement height of the branch pipe wound with the emery cloth material so that the wound emery cloth material is closer to the processing area of ​​the shaping machine. However, the branch pipe wound with emery cloth is relatively heavy and large in size, which makes it difficult and troublesome to lift the branch pipe wound with emery cloth material, thereby affecting the unwinding efficiency. In addition, in the process of unwinding the branch pipe wound with emery cloth material, it is necessary to first take out the branch pipe in the unwinding position, and then place the branch pipe wound with emery cloth material in the unwinding position. For this reason, the unwinding operation needs to complete the pre-operation of taking out the branch pipe first, which makes the unwinding operation very inconvenient. Furthermore, if the branch tube at the unwinding position is forgotten to be taken out first, that is, when the branch tube with the abrasive cloth material is lifted and it is found that the branch tube originally placed is not taken out, the branch tube with the abrasive cloth material needs to be put back to the position before lifting, and then the branch tube at the unwinding position needs to be taken out before the unwinding operation can be performed, resulting in the need for repeated unwinding operations. Therefore, there is still room for improvement in the unwinding of abrasive cloth, so as to further meet the production needs of abrasive cloth. Summary of the invention

At the same time, with the help of the motor drive, the support frame 8 at the top of the turntable 3 rotates toward the bottom of the turntable 3, and the branch tube set in the support frame 8 will slide out from the open end of the support frame 8 to avoid the operation of taking out the branch tube. It should be noted that a bearing is provided on the support 2, and the inner ring of the bearing and the outer ring of the bearing are respectively connected to the turntable 3 and the support 2, so that the support 2 is rotatably connected to the turntable 3.

[0025] Please refer again Figure 2 and 4 A bracket 16 is provided between the rotating motor 4 and the telescopic motor 9, and the two sides of the bracket 16 are respectively installed on the rotating motor 4 and the telescopic motor 9. A distance measuring sensor 17 is provided on the bracket 16, and the distance measuring end of the distance measuring sensor 17 faces the fixed rod 11. The distance is detected by the distance measuring sensor 17, that is, when the support rod 7 is located between the distance measuring sensor 17 and the fixed rod 11, the distance detected by the distance measuring sensor 17 becomes shorter, so as to determine the position of the support rod 7, so as to facilitate the use of the clamping device to clamp the branch pipe located at the top of the turntable 3.

[0026] In this embodiment, two cover plates 18 are provided on the frame 1, and the two cover plates 18 are respectively provided with a groove 19, and the two discs 5 are respectively mounted in the grooves 19 opened in the two cover plates 18, so as to restrict the two ends of the branch pipe placed in the support frame 8, prevent the branch pipe from sliding out along the two end directions of the branch pipe, and prevent the branch pipe from colliding with the rotating motor 4 or the telescopic motor 9 during the placement of the branch pipe.

After the branch pipe is placed in the support frame 8 at the bottom of the rotating disk 3, the branch pipe is prevented from sliding out of the support frame 8 due to inertia and other factors, so as to improve the stability of the placement of the branch pipe.

[0029] The assembly and debugging methods of this product are as follows: Figures 1 to 7 As shown, first, the frame 1 is installed on the feeding side of the shaping machine so that the support frame 8 located at the top of the turntable 3 is close to the processing area of ​​the shaping machine. The rotating motor 4, the telescopic motor 9 and the distance sensor 17 are connected to the electric control terminal respectively. Then, the product is tested, that is, the branch pipe is placed in the support frame 8 located at the bottom of the turntable 3, and the telescopic motor 9 is controlled by the electric control terminal to shorten the operation, and then the rotating motor 4 is started to operate, so that the branch pipe rotates to the top of the turntable 3. According to the signal detected by the distance sensor 17 that the distance is getting closer, the electric control terminal stops the operation of the rotating motor 4, and at the same time controls the telescopic motor 9 to extend the operation to observe whether the branch pipe is clamped between the clamping plate 12 and the clamping rod 10. If the branch pipe is clamped between the support plate 12 and the clamping rod 10, the support rod 7, the distance sensor 17, the electric control terminal, etc. are adjusted until the use requirements are met.

[0030] The rotating motor 4 provided in this embodiment drives the turntable 3, the disc 5, the rotating shaft 6, the support rod 7 and the support frame 8 to rotate, so that the support rod 7 located at the bottom of the turntable 3 rotates to the top of the turntable 3, and the branch pipe wound with the abrasive cloth material is set in the support frame 8 located at the bottom of the turntable 3, so that the branch pipe wound with the abrasive cloth material rotates to the top of the turntable 3, so as to facilitate the lifting operation, and pull one end of the abrasive cloth wound with the branch pipe to the processing area of ​​the shaping machine, so as to facilitate the product operation. At the same time, the support frame 8 located at the top of the turntable 3 rotates to the bottom of the turntable 3, and the branch pipe set in the support frame 8 will slide out from the open end of the support frame 8, so as to avoid the operation of taking out the branch pipe, thereby improving the convenience of unwinding. Moreover, during the processing of the shaping machine, the branch pipe wound with the abrasive cloth material can be placed in the support frame 8 located at the bottom of the turntable 3, so that when the branch pipe needs to be replaced, it is only necessary to control the rotating motor 4 to reduce the difficulty of unwinding.
