Description

Technical Field

[0001] The utility model relates to the technical field of resin rod processing, in particular to a resin rod cutting device. Background Art

[0002] Resin rods are usually formed by melting resin particles at high temperature and then extruding them through an extruder. The length of the resin rods extruded by the extruder is usually longer, so they need to be cut into resin rods of appropriate length as needed.

[0003] In order to ensure that the cutting surface of the resin rod is flat, intermittent feeding is usually performed. When the resin rod is stopped, it is cut by a cutting knife. To achieve intermittent feeding, one method in the prior art is to clamp the resin rod together by an actively rotating conveying wheel and an auxiliary conveying wheel, and then the conveying wheel rotates intermittently under the drive of repeated start and stop of the motor, thereby achieving intermittent feeding. Since the motor will increase the power consumption at the moment of starting and rotating, the power consumption of the equipment will increase when the motor is frequently started and stopped.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] A resin rod cutting device comprises a workbench 1, on which a supporting structure, an intermittent feeding structure and a cutting structure are sequentially arranged along the conveying direction of the resin rod.

[0023] The support structure is used to support the resin rod for transportation;

[0024] The intermittent feeding structure is used for intermittently conveying resin rods, and includes two meshingly connected rotating gears 3, one of which is driven to rotate by a rotating motor 5. A vertical rotating shaft is installed on the workbench 1, and the rotating shaft is rotatably installed on the workbench 1. The rotating gear 3 is fixedly installed on the rotating shaft, and the rotating motor 5 drives the rotating shaft to rotate. The central axis of the rotating gear 3 is vertically arranged, and the connecting line of the two rotating gears 3 is perpendicular to the conveying direction of the resin rods. A horizontally arranged fan-shaped feeding block 4 is fixedly arranged on the upper end of the rotating gear 3, and the fan-shaped feeding block 4 has an arc-shaped side surface. The feeding blocks 4 on the two rotating gears 3 are symmetrically arranged and rotate synchronously in opposite directions at the same speed. The rotation center of the feeding block 4 is located on the same vertical line as the rotation center of the rotating gear 3, and the rotation center of the feeding block 4 coincides with the fan-shaped circle. The two The closest distance between the arc surfaces of the feed blocks 4 matches the width of the resin rod, and the resin rod passes between the two feed blocks 4; the two feed blocks 4 rotate synchronously with the rotating gear 3, and when the arc surfaces of the two feed blocks 4 rotate to press on one side of the resin rod, the two feed blocks 4 clamp the resin rod together, and convey the resin rod forward as the feed blocks 4 rotate, and the conveying distance of the resin rod matches the arc length of the feed blocks 4. Since the resin rod has a certain elasticity, the closest distance between the arc surfaces of the two feed blocks 4 can actually be slightly smaller than the width of the resin rod, thereby ensuring that the arc surfaces of the two feed blocks 4 can clamp the resin rod for conveying. When the arc surface of the feed block 4 rotates to leave the surface of the resin rod, the conveying of the resin rod stops, thereby achieving intermittent conveying of the resin rod under the continuous uniform speed output of the rotating motor 5, and reducing the power consumption of the rotating motor 5;

[0025] The cutting structure is used for cutting the resin rods.

[0026] According to a preferred technical solution, the feed block 4 is detachably mounted on the upper end of the rotating gear 3 by means of a locking bolt. Since the conveying distance of the resin rods matches the arc length of the feed block 4, resin rods of different lengths can be cut by replacing the feed blocks 4 with different arc lengths.

[0027] A preferred technical solution is that a strip-shaped convex edge is protruding from the upper end of the rotating gear 3, and the length direction of the convex edge is arranged along the radius direction of the rotating gear 3. The lower end of the feed block 4 has a strip groove matching the convex edge, and the strip groove is clamped on the convex edge. In this way, the cooperation between the strip groove and the convex edge can avoid slipping between the feed block 4 and the rotating gear 3.

[0028] The preferred technical solution is that the cutting structure includes a support table 6, a cutting knife 10, a cylinder 9 and a bracket 8. The support table 6 is fixedly installed on the workbench 1, and the cylinder 9 is vertically installed above the workbench 1 through the bracket 8. The telescopic rod of the cylinder 9 is connected to the cutting knife 10 downward, and the blade of the cutting knife 10 is downward. The blade of the cutting knife 10 can be in contact with the side of the support table 6 away from the intermittent feeding structure. After the resin rod passes through the intermittent feeding structure, it passes through the upper end surface of the support table 6, and the part to be cut extends out of the edge of the support table 6. The cutting knife 10 is driven by the cylinder 9 to descend and cut the resin rod. The position setting of the cutting knife 10 and the support table 6 can form a shear force with one side edge of the support table 6 when the cutting knife 10 descends, which is more conducive to cutting the resin rod.

[0029] According to a preferred technical solution, the support platform 6 is detachably mounted on the workbench 1 by means of mounting bolts, and a limiting groove 7 matching the resin rod is provided on the upper end surface of the support platform 6, and the resin rod passes through the limiting groove 7, and the limiting groove 7 is used to restrict the resin rod to prevent it from swinging.

[0030] According to a preferred technical solution, the support structure includes a feeding trough 2 arranged along the conveying direction of the resin rod, and the feeding trough 2 matches the resin rod.
