Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of filter membrane paper tapes, in particular to a filter membrane paper tape clamping device. Background Art
[0002] The filter paper tape is composed of a round plastic sleeve and a long strip of filter paper. The filter paper is wound around the plastic sleeve in circles. The whole finished product is similar to a transparent tape, with a hole in the middle for threading the shaft. In order to make the filter paper tape move smoothly and accurately on the instrument, it is necessary to fix the filter paper tape so that it can release and tighten the paper tape as the motor rotates.
[0003] The current method of clamping paper tape on the market is "end clamping method": that is, a shaft is passed through the hole in the middle of the paper tape to ensure that it is concentric with the paper tape, and circular baffles are added at both ends of the paper tape, and the threads are used to squeeze the paper tape from both ends until it is clamped to the plastic bushing and fixed, and finally the shaft is connected to the motor. In this way, the paper tape can be released and tightened as the motor rotates.
[0004] This clamping method clamps from both ends, and there is a matching tolerance between the paper tape and the plastic bushing. Also, because the plastic bushing is cut from plastic tubes on the market and is different from paper tape manufacturer to paper tape manufacturer, some paper tapes cannot be installed after assembly, and some plastic bushing circles are too large to ensure concentricity with the shaft, causing inconvenience in use and reduced paper moving accuracy of the instrument. Utility Model Content
[0005] The utility model aims to provide a filter membrane paper tape clamping device to solve the problems raised in the above background technology.
[0006] The technical solution adopted by the utility model is as follows:
[0007] A filter membrane paper tape clamping device comprises a rear clamping plate and a front clamping plate, wherein a paper tape bushing is sleeved on the outer side of one end adjacent to the rear clamping plate and the front clamping plate, and a rotating shaft is inserted at the center of the rear clamping plate and the front clamping plate.
[0008] Preferably, a locking nut is screwed onto the front end of the rotating shaft, and the rear end of the rotating shaft is connected to the output shaft of the motor via a coupling.
[0009] Preferably, a clamping head is provided at one adjacent end of the rear clamping plate and the front clamping plate, and the connection parts between the rear clamping plate and the front clamping plate and their corresponding clamping heads are rounded.
[0010] Preferably, the outer sides of the two clamping heads of the paper tape bushing and the connection between the paper tape bushing and the clamping heads are provided with buffer washers.
[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
[0012] In the utility model, the paper tape bushing is fixed by the clamping heads of the front and rear clamping plates, so the concentricity of the paper tape bushing and the rotating shaft can be ensured, the use is more convenient, and the paper moving accuracy of the instrument is improved.

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0018] Example:
[0019] A filter paper tape clamping device, such as Figure 1-2 As shown, it includes a rear clamping plate 1 and a front clamping plate 2, a paper tape bushing 3 is sleeved on the outer side of one end adjacent to the rear clamping plate 1 and the front clamping plate 2, and a rotating shaft 5 is inserted at the center of the rear clamping plate 1 and the front clamping plate 2.
[0020] In a possible implementation manner, a locking nut 6 is screwed onto the front end of the rotating shaft 5 , and the rear end of the rotating shaft 5 is connected to the output shaft of the motor 8 via a coupling 7 .
[0021] In a possible implementation, a clamping head is provided at one adjacent end of the rear clamping plate 1 and the front clamping plate 2, and the connection portions between the rear clamping plate 1 and the front clamping plate 2 and their corresponding clamping heads are rounded.
[0022] In a possible implementation manner, buffer washers 4 are provided on the outsides of the two clamping heads of the paper tape bushing 3 and at the connection between the paper tape bushing and the clamping heads.
[0023] In a possible implementation manner, the rotating shaft 5, the coupling 7 and the motor 8 are all arranged on a workbench and provided with a corresponding supporting structure (not shown in the figure).
[0024] Working principle, see Figure 1-3When in use, rotate the locking nut 6. Because there is a gap between the front and rear splints, the buffer washer 4 will be squeezed and deformed when locking. Because the front and rear splints have inclined surfaces where the buffer washer 4 is placed, the squeezed buffer washer 4 will expand outward, thereby squeezing the inner wall of the paper tape sleeve 3 of the filter membrane paper tape, thereby achieving the purpose of locking the filter membrane paper tape.
[0025] like Figure 3 As shown, A is a schematic diagram of the force on the filter membrane paper tape in the present application, and B is a schematic diagram of the force on the filter membrane paper tape in the prior art. It can be clearly seen that the paper tape sleeve 3 in the present application is subjected to outward expansion force, which can ensure the concentricity of the paper tape sleeve 3 and the rotating shaft, making it more inconvenient to use and improving the paper moving accuracy of the instrument.
[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
