Description

Fixing structure for detecting paper towel tearing

Technical Field

The utility model relates to a paper handkerchief production check out test set's technical field, more specifically say, it relates to a paper handkerchief tears and detects and uses fixed knot to construct.

Background

In the production process of the paper towel, after the paper towel is formed, the tear resistance of the paper towel needs to be detected, the two ends of the paper towel are clamped tightly by the existing detection device through the clamp, and then the clamp is forced to push and pull in two opposite directions. The existing clamp is easy to damage the end face of the paper towel when clamping the paper towel, and the clamp is easy to break when stressed on the paper towel, so that the anti-tearing detection data of the paper towel is inaccurate.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a rational in infrastructure simple, the practicality is strong, is difficult for causing the paper handkerchief damaged when fixed to the paper handkerchief, improves to tear the paper handkerchief that detects the precision and tears and detect and use fixed knot to construct.

In order to achieve the above purpose, the utility model provides a following technical scheme:

the fixed knot that detects is torn to paper handkerchief constructs, and fixed knot constructs and is provided with two, arranges the both ends of paper handkerchief respectively and is used for taut paper handkerchief, fixed knot constructs including arranging in proper order and sets up first roller part, second roller part and compresses tightly the subassembly, first roller part and second roller part constitute by mount and roller combination, compress tightly the subassembly including the support and with support swing joint's last compression roller and lower compression roller, go up the compression roller and have with the both ends of lower compression roller with the connecting rod of leg joint, the roller of first roller part sets up highly is higher than the height of the roller of second roller part, the paper handkerchief is earlier around on the roller of first roller part, and the back is held fixedly by last compression roller and lower compression roller.

The utility model discloses further set up to: the support corresponds and is provided with two, sets up jaggedly on the support, and the connecting rod runs through the breach through the both ends of going up compression roller and lower compression roller, and threaded connection has lock nut on the connecting rod.

The utility model discloses further set up to: the inner walls of the notches are arranged in a tooth shape.

The utility model discloses further set up to: the roll shaft of the first roll shaft part and the roll shaft of the second roll shaft part comprise an inner cylinder and an outer cylinder, the outer cylinder and the inner cylinder are rotatably connected, rod pieces are arranged at two ends of the inner cylinder and connected with the fixing frame, and baffle plates used for limiting the outer cylinder are connected onto the rod pieces.

The utility model discloses further set up to: a first graphite block is embedded in the inner wall of the inner cylinder, and a second graphite block is embedded in the outer wall of the inner cylinder.

Contrast prior art not enough, the beneficial effects of the utility model are that:

the paper towel is wound on the roller shaft of the first roller shaft part, passes through the roller shaft of the second roller shaft part, and is clamped and fixed by the upper pressing roller and the lower pressing roller. Utilize first roller part and second roller part table curved surface to come the paper handkerchief tensioning, utilize last compression roller and lower compression roller to realize that the centre gripping is fixed at last, with roller curved surface and paper handkerchief contact, avoided when tearing the paper handkerchief, paper handkerchief central point puts and does not split, the damaged condition earlier of its centre gripping department, improved the precision that detects greatly.

Detailed Description

Embodiments of the present invention are further described with reference to fig. 1 to 3.

The embodiment has the specific structure that: the two fixing structures are respectively arranged at the two ends of the paper towel 4 and used for tensioning the paper towel 4. The fixed structure is installed on the working table surface of the frame, a sliding rail and an air cylinder are further arranged on the working table surface, a sliding guide rail matched with the sliding rail is installed at the bottom of the fixed structure, the output end of the air cylinder is connected with the fixed structure, the fixed structure is controlled to slide on the sliding rail, and therefore the paper towel 4 is torn.

The fixing structure comprises a first roller shaft part 1, a second roller shaft part 2 and a pressing assembly 3 which are sequentially arranged.

The first roller shaft part 1 and the second roller shaft part 2 are both composed of a fixed frame 11 and a roller shaft 12, and the roller shaft 12 of the first roller shaft part 1 is arranged to be higher than the roller shaft 13 of the second roller shaft part 2.

The roller of first roller part 1 and second roller part 2 includes interior barrel 302 and outer barrel 301, and outer barrel rotates with interior barrel to be connected, and the both ends of interior barrel have member 121, and the member runs through 121 and locks the body of rod and mount 11 through fixation nut 122 behind the locating hole on the mount 11, moreover, is connected with on the member to be used for the spacing baffle 7 of outer barrel. The baffle 7 can limit the paper towel 4.

The inner wall of the inner cylinder 302 is embedded with a first graphite block 312, and the outer wall of the inner cylinder is embedded with a second graphite block 311. The graphite block has a lubricating effect, and when the outer cylinder body rotates relative to the inner cylinder body, the rolling friction force of the outer cylinder body and the inner cylinder body is greatly reduced.

The pressing component 3 comprises a bracket 31, an upper pressing roller 32 and a lower pressing roller 33 which are movably connected with the bracket, and two ends of the upper pressing roller and the lower pressing roller are provided with connecting rods 5 connected with the bracket. The paper towel 4 firstly winds on the roller shaft of the first roller shaft part 1, then passes through the roller shaft of the second roller shaft part 2, and finally is clamped and fixed by the upper compression roller and the lower compression roller.

Support 31 corresponds and is provided with two, has seted up breach 30 on the support, and the connecting rod runs through breach 30 is passed through at the both ends of going up compression roller and lower compression roller, and the inner wall of breach is the cusp and arranges. The connecting rod 6 is connected with a locking nut 5 through threads.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and the skilled in the art can carry out the common changes and replacements within the technical solution of the present invention.
