In the above scheme, the up-down moving mechanism comprises a slide rail, a slide block and a cylinder, the slide rail is fixed on the side face of the wallboard, the slide block is arranged on the slide rail and moves up and down, the guide roller is fixed on the slide block through a bearing with a seat, and the cylinder for controlling the slide block to move up and down is connected on the slide block.

In the scheme, the air cylinder is fixed on the upper end face of the wallboard through the air cylinder support plate.

In the scheme, the extending shaft end of the cylinder is provided with the floating joint, and the extending shaft of the cylinder is fixed with the upper end of the sliding block through the floating joint.

In the above scheme, the guide rollers arranged side by side are provided with the up-and-down moving mechanism at intervals, and the wallboards at the two ends of the guide rollers provided with the up-and-down moving mechanism are provided with the abdicating long slotted holes.

In the above scheme, the up-down moving mechanism is a linear guide rail pair.

Compared with the prior art, the multi-roller safe material penetrating mechanism has the beneficial effects that:

1. the use of the movable roller thoroughly eliminates the potential safety hazard faced by an operator in the process of material penetration.

2. Because the roller spacing required in the process of material penetration is not considered, the roller spacing can be designed to be as small as possible, and thus, the processing technology requirement is met to a great extent.

3. The adoption of the mechanism also greatly shortens the material penetrating time, and the material penetrating work is simple and convenient.

In the figure: 1. the device comprises a cylinder, 2 a cylinder support plate, 3 a floating joint, 4 a wallboard, 5 a slide rail, 6 a slide block, 7 a seated bearing, 8.1# guide roller, 9.2# guide roller, 10 a material film, 11.3# guide roller, 12.4# guide roller and 13 a long slotted hole.

Detailed Description

The utility model further discloses a multi-roller safe material penetrating mechanism by combining the following drawings and specific embodiments:

fig. 1 is a schematic structural diagram of a multi-roller safe material penetrating mechanism of the utility model, and fig. 2 is a side view of fig. 1. In the picture, this multiroll safety wears material mechanism includes both sides wallboard 4, four deflector rolls of horizontal arrangement side by side between the wallboard 4 of both sides, material membrane 10 is S-shaped and walks around four deflector rolls in proper order, 1

# deflector roll

8 and 3# deflector roll 11' S both ends all are provided with reciprocating motion, reciprocating motion includes slide rail 5, slider 6 and cylinder 1, the medial surface at wallboard 4 is fixed to slide rail 5, slider 6 sets up and reciprocates on slide rail 5, 1

# deflector roll

8 and 3# deflector roll 11 are fixed on slider 6 through rolling bearing 7, be connected with the cylinder 1 that the control slider reciprocated on slider 6. The cylinder 1 is fixed on the upper end face of the wallboard 4 through the cylinder support plate 2, the extending shaft end of the cylinder 1 is provided with a floating joint 3, and the extending shaft of the cylinder 1 is fixed with the upper end of the sliding block 5 through the floating joint 3. And the wall plates at the two ends of the 1# guide roller 8 and the 3# guide roller 11 are provided with abdicating long slotted holes 13.

The 1# guide roller and the 3# guide roller can also be directly fixed on the wall plate through the linear guide rail pair, so that the up-and-down movement precision of the guide rollers can be better improved.

When the material is threaded, the air cylinder 1 retracts, the 1# guide roller 8 and the 3# guide roller 11 are lifted to a sufficient height, namely the vertical distance between the 1# guide roller 8 and the 3# guide roller 11 and the 2# guide roller 9 and the 4# guide roller 12 reaches the height which is enough to safely thread the material without damaging arms, and the material film 10 is directly pulled from right to left without winding any roller. After the material film 10 is pulled out of all four guide rollers, the air cylinder extends out, and then the No. 1 guide roller 8 and the No. 3 guide roller 11 descend to the normal operation position, as shown in figure 2, the machine can start to operate. As long as enough safe distance is reserved between the upper and lower groups of guide rollers, the material film can be easily pulled from one end to the other end, and potential safety hazards cannot occur. After the lifted guide roller falls down, the requirements of small enough roller spacing and reasonable feeding mode can be completely met.

The multi-roller safe material penetrating mechanism does not need to consider the roller distance required in material penetrating, so the roller distance can be designed to be as small as possible, the processing technology requirement is met to a great extent, the material penetrating time is greatly shortened, and the material penetrating work is simple and convenient.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the utility model as defined by the appended claims.
