Detailed Description
To further disclose the contents, features and functions of the present invention, the following examples are given in detail in conjunction with the accompanying drawings.
Example (b): referring to fig. 1-2, a felt roll holding plate 12 includes a central shaft 121 and plate bodies 122 installed at both ends of the central shaft, the plate bodies 122 and the central shaft 121 being fixed by locking rings 123; a tensioning hand wheel 124 is installed on the locking ring 123, an adjusting rod 125 is installed in the tensioning hand wheel 124, and the other end of the adjusting rod 125 is connected with a mandrel 127; the mandrels 127 are connected through a connecting rod 126, and tensioning blocks 128 are arranged on the outer sides of the mandrels 127; the tensioning block 128 is located at the opening of the central shaft 121, and the tensioning block 128 is fixed at the opening through a rubber ring 129.
As shown in fig. 3-4, the center of the disc 122 is provided with a catch 1221, the catch 1221 matching with the protrusion 1211 at the end of the central shaft 121. The structural cooperation of the catch 1221 and the projection 1211 ensures that the disk 122 does not rotate relative to the central shaft 121.
As shown in fig. 5, the mandrel 127 is circular truncated cone and has a trapezoidal cross section, and the middle portions of the upper and lower bottom surfaces of the mandrel 127 are provided with slots. The upper and lower bottom surfaces of the spindle 127 require the insertion of an adjusting lever 125 or a connecting lever 126. The bottom surface of the slot is conical. The mandrel 127 is made of aluminum, and the bottom surface of the tapered slot is beneficial to reducing abrasion among parts. The lower part of the adjusting rod 125 is provided with a spring and is connected with the mandrel 127, and the mandrel 127 and the tension handwheel 124 can be reset conveniently after the locking ring 123 is loosened.
As shown in fig. 6, the tensioning block 128 is a right-angled trapezoidal block; the bevel edge 128 of the tensioning block abuts the side of the mandrel 127. The number of the tension blocks 128 is the same as that of the opening of the central shaft 121, and the shape of the tension blocks 128 is matched with that of the mandrel 127, so that the mandrel 127 is pushed out of the opening of the central shaft 121 when being stressed, and the function of tensioning the axis of the felt roll is achieved. Positioning grooves are formed in the right-angle side of the tensioning block 128 and the corresponding position of the central shaft 121, and the rubber ring 129 is located in the positioning grooves. The positioning groove is designed to prevent the elastic member from deviating from the opening of the central shaft 121 when the elastic member is tensioned outwards by the tensioning block 128, so that the fixing effect on the tensioning block 128 is lost.
As shown in fig. 7-8, the central shaft 121 is a hollow circular tube with an opening on the surface, the opening is strip-shaped, and 3 of the four groups are uniformly distributed on the tube wall; the locking ring 123 fastens the adjusting rod 125 and the tightening handwheel 124 to the central shaft 121 by means of a positioning bolt.
The working principle is as follows: the tensioning hand wheel is screwed down to compress the spring, the positions of the disk body and the mandrel on the central shaft are adjusted, the mandrel extrudes the tensioning block from the opening of the central shaft, and the tensioning block protrudes out of the surface of the central shaft to clamp the axis of the felt roll, so that the rotation of the axis of the felt roll in the rolling process is prevented. When the clamping disc needs to be disassembled, the locking ring is loosened to reset the spring, the mandrel and the tensioning hand wheel are reset, and the tensioning block retracts into the central shaft.
Although the preferred embodiments of the present invention have been described, the present invention is not limited to the above-mentioned embodiments, which are only illustrative and not restrictive, and those skilled in the art can make many forms without departing from the spirit and scope of the present invention. All of which fall within the scope of the present invention.
