The invention provides a fixed-length cutting device for PVC foam boards, which is further described in detail below by referring to the attached drawings and examples in order to make the purpose, technical scheme and effect of the invention clearer and clearer. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 3 and 4, the present invention provides a fixed length cutting device for PVC foam board, which comprises a conveying frame 1 and a frame driving mechanism 2 for driving the conveying frame 1 to move, and the fixed length cutting device for PVC foam board can be arranged at the downstream of the fixed width cutting device for the foam board.
As shown in fig. 1 and 3, the conveyor frame 1 further includes a driving roller group 11, a cutting platform 12, a cutting mechanism 13, and a platen mechanism 14.
The transmission roller set 11 comprises a plurality of transmission rollers, and after the foam board is cut to be constant in width, the foam board is continuously transported under the action of the transmission rollers (the power for the foam board to move forwards comes from a tractor of a PVC foam board production system, and the tractor can push the foam board forwards).
The pressing plate mechanism 14 is used for pressing the foaming plate on the cutting platform 12 when the foaming plate is cut.
As shown in fig. 5 to 7, the cutting mechanism 13 includes a tool holder 131, a cutting blade 132 disposed on the tool holder 131, a rolling mechanism disposed on the tool holder 131, and a first driving mechanism 133 for driving the tool holder 131 to move up and down.
Specifically, the knife seat 131 can move up and down under the action of the first driving mechanism 133, when the cutting blade 132 is disposed on the knife seat 131, the knife seat 131 can drive the cutting blade 132 to upwards penetrate through the cutting platform 12, and then when the pressing mechanism 14 presses the foam board onto the cutting platform 12, the cutting blade 132 can act on the foam board. In addition, the knife holder 131 can also be driven by the second driving mechanism 3 arranged on the conveying frame 1, when the second driving mechanism 3 works, the knife holder 131 can reciprocate along the width direction of the foaming board, and through the cooperation of the first driving mechanism 133 and the second driving mechanism 3, the cutting blade 132 can move along the width direction of the foaming board after passing through the cutting platform 12 upwards, so as to realize the fixed-length cutting of the foaming board (the length of the foaming board is the length of the board after the cutting blade 132 cuts twice).
Specifically, the rolling mechanism is disposed at a position in the same line as the cutting blade 132, and includes a mounting tube 134 and a ball 135 disposed at an opening at an upper end of the mounting tube 134. The cutting platform 12 is provided with a cutting groove 4 suitable for the cutting blade 132 and the rolling mechanism to penetrate upwards. The rolling mechanism is located lower than the cutting blade 132 on the knife holder 131, and when the cutting blade 132 passes through the cutting platform 12 upwards and cuts the foam board, the rolling mechanism is located in the cutting groove 4, and the ball 135 presses the lower surface of the foam board upwards. Along with cutting blade 132 cuts the fixed length to the foaming board, rolling mechanism also can move along the width direction of foaming board to the messenger just to the notched ball 135 roll extrusion foaming board's of PVC foaming board lower surface (the incision forms after cutting blade 132 cutting foaming board, therefore rolling mechanism's setting needs to satisfy the mode of the operation of cutting earlier back roll extrusion), and make the foaming board by the part of cutting blade 132 downward extrusion and be consolidated and flatten through the roll extrusion of ball 135, avoided the formation of foaming board both sides lower part deckle edge.
In addition, since the rotation direction of the ball 135 itself is random, when the ball 135 rolls, the surface of the object to be rolled can be uniformly stressed, so as to ensure that the part of the foam board extruded downwards by the cutting blade 132 can be compacted and flattened, and the situation of edge breakage of the board material can not occur.
As shown in fig. 3 and 4, when the cutting blade 132 cuts a fixed length, the frame driving mechanism 2 drives the entire conveying frame 1 to move in the conveying direction of the foam board, so that the foam board can be conveyed forward even if the foam board is pressed by the pressing mechanism 14 during cutting operation, and normal board discharge of the extruder is not affected.
As shown in fig. 7 and 8, further, the cutting blade 132 includes a first cutting blade 132a and a second cutting blade 132b which are disposed on the same line. The first cutting blade 132a is located lower than the second cutting blade 132b on the blade holder 131, and the first cutting blade 132a is used to perform preliminary cutting on the foam board. When the tool rest 131 moves to perform a cutting operation, the first cutting blade 132a first acts on the foam board, and the cutting depth of the first cutting blade 132a is lower than the thickness of the foam board, and after the foam board has formed a certain cutting depth, the second cutting blade 132b further cuts deeply. When the thickness of foaming plate is thick, the aforesaid cuts the mode and can avoid the blade to appear the problem of warping in the in-process of once only cutting foaming plate.
Because cutting blade 132 can not warp when cutting the foaming board, therefore can ensure the cutting quality of foaming board, also can ensure in addition that the foaming board cuts the incision that forms and is parallel with the width direction of foaming board all the time, makes the incision that ball 135 can act on the foaming board lower surface all the time like this, ensures that the deckle edge that the foaming board fixed length cut produced can be eliminated.
As shown in fig. 8 and 9, the holder 131 further includes a first seat plate 131a and a second seat plate 131b having the same shape, and the first seat plate 131a and the second seat plate 131b can be assembled by fastening bolts with screws.
