Has the advantages that:
the utility model provides a PVC board side cut hold-down mechanism, the subassembly that compresses tightly in cutting device's frame top both sides, every side is provided with two at least and compresses tightly the subassembly, every flange is compressed tightly on the side of PVC board by two piece at least elastic pressing strips, and because compress tightly the subassembly setting in cutting device's frame, can remove along with cutting device at the cutting device during operation, consequently the relative PVC board is static at the cutting device during operation, thereby can prevent that the sideboard from taking place the swing, and then ensure can not because the sideboard swing leads to cutting edge uneven, reduce the defective rate of product.
Drawings
Fig. 1 is the utility model provides a PVC board side cut hold-down mechanism's schematic structure.
Fig. 2 is the utility model provides an among the PVC board side cut hold-down mechanism, compress tightly the structural schematic diagram of subassembly.
FIG. 3 is a top view of a PVC sheet production system.
Detailed Description
The utility model provides a PVC board side cut hold-down mechanism, for making the utility model discloses a purpose, technical scheme and effect are clearer, clear and definite, and it is right that the embodiment is lifted to follow with reference to the drawing the utility model discloses further detailed description. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
herein, the rear means the direction of conveyance of the PVC sheet, i.e., the direction of the arrow in FIG. 3, and the front and rear are reversed.
Referring to fig. 1-2, the utility model provides a PVC plate trimming hold-down mechanism, which comprises a plurality of hold-down components arranged on both sides of the top of a frame 5.1 ' of a cutting device 5 ' of a PVC plate production system, at least two hold-down components are arranged on each side of the frame 5.1 '; each pressing component comprises a mounting seat 1 arranged on the rack 5.1' and an elastic pressing strip 2 arranged on the mounting seat; one end of the elastic pressing strip is inclined along the conveying direction of the PVC plate and pressed on the outer side surface of the plate edge 91 (namely, one end of the elastic pressing strip, which is in contact with the plate edge, is behind the other end).
During operation, every flange is compressed tightly on the side of PVC board by two piece at least elastic pressing strips (promptly PVC board 90 and elastic pressing strip clip flange 91 jointly), and owing to compress tightly the subassembly setting in cutting device's frame, can remove along with cutting device at cutting device during operation (moving speed equals with the moving speed of PVC board), consequently the relative PVC board is static at cutting device during operation, thereby can prevent effectively that the sideboard from taking place the swing, and then ensure not to lead to cutting edge uneven because the sideboard swing, reduce the defective rate of product.
Further, the mounting seat 1 is pivotally connected with the frame 5.1', an arc-shaped waist hole 1.2 concentric with the pivot shaft 1.1 is formed in the mounting seat, and the mounting seat is locked by a locking screw 3 penetrating through the waist hole 1.2.
