Description

Technical Field

[0001] The invention relates to the technical field of heat shrinkable tube processing equipment, in particular to an adjustable PET heat shrinkable tube end surface flattening device. Background Art

[0002] Heat shrink tubing, also known as heat shrink protection tubing, provides insulation protection for wires, cables and wire terminals. It has high temperature shrinkage, soft flame retardancy, insulation and corrosion resistance, etc. It is widely used for insulation protection of various wiring harnesses, solder joints, inductors and rust and corrosion prevention of metal pipes and rods. After production and processing, the end of a type of PET heat shrink tubing will have uneven end faces, so it needs to be leveled.

[0003] The existing leveling method is to press the PET heat shrink tubing mechanically and cut the end with a knife. This method can achieve perfect cutting for softer heat shrink tubing, but for PET heat shrink tubing with higher hardness, the end is prone to cracking during cutting. If it is polished by a polishing device, the efficiency is low. If the end face is not vertical, polishing alone will take a long time and easily generate powder flying. Summary of the invention

[0004] The object of the present invention is to provide an adjustable PET heat shrink tubing end surface flattening device to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is an adjustable PET heat shrinkable tube end surface leveling device, comprising a device base, a clamping mechanism and a leveling mechanism, wherein the clamping mechanism and the leveling mechanism are both fixedly mounted on the upper surface of the device base;

[0007] The leveling mechanism includes a support frame and a ring rail, the ring rail is composed of two symmetrical sawtooth rings and a snap ring, the two sawtooth rings are fixedly connected to two snap rings respectively, and an adjustable cutting mechanism is arranged between the two sawtooth rings;

[0008] The adjustable cutting mechanism includes a sliding bin, a double-headed rotating motor is fixedly installed on the inner wall of the sliding bin, two output shafts of the double-headed rotating motor are fixedly connected to a group of driving components, and the two driving components include multiple rollers. A cutting component is arranged at the central axis of the sliding bin, and the cutting component includes a rotating cylinder and a fixed shell. The inner wall of the fixed shell is rotatably connected to the driving shaft, and the outer wall of the driving shaft is fixedly connected to the driving gear. A driven gear is arranged below the driving gear and its teeth are meshed with the teeth of the driving gear. The outer wall of the driven gear is fixedly connected to a driven rod, and the outer wall of the driven rod is rotatably connected to a U-shaped connecting piece, and the outer wall of the U-shaped connecting piece is fixedly connected to a telescopic rod, the inner wall of the fixed shell is fixedly connected to a limiting ring, and the inner wall of the fixed shell is slidably connected to a telescopic inner shell.

[0009] Furthermore, the equipment base includes an equipment cabin, a movable base and a fixed base, the outer wall of the equipment cabin is fixedly connected to the outer wall of the fixed base, the inner wall of the equipment cabin is slidably connected to the outer wall of the movable base, the inner wall of the equipment cabin is fixedly installed with a driving motor, two screw rods are arranged inside the equipment cabin, one end of one screw rod is fixedly connected to the output shaft of the driving motor, one end of the other screw rod is rotatably connected to the inner wall of the equipment cabin, a transmission belt is transmission-connected between the two screw rods, both of the two screw rods pass through the movable base and are rotatably connected to the inner wall of the fixed base, the outer wall of the movable base is symmetrically fixedly connected with a telescopic plate, the inner wall of the fixed base is provided with a sliding groove, the outer wall of one telescopic plate is slidably connected to the inner wall of the sliding groove, the inner wall of the equipment cabin is fixedly connected to the fixed plate, and the outer wall of the other telescopic plate is slidably connected to the outer wall of the fixed plate.

[0010] By adopting the above technical scheme, the movement effect of the clamping mechanism is realized, and the parts in the equipment cabin are protected, thereby extending their service life. The output shaft of the driving motor drives the screw to rotate, and the rotation of the screw drives the movable base to move horizontally, so that the clamping mechanism is moved in front of the casing transmission device. At this time, one of the telescopic plates slides into the fixed base, and the other telescopic plate slides and stretches on the fixed plate, so that the equipment cabin is always in a closed state to prevent dust generated by cutting or cut casing from falling into the equipment cabin.

[0011] Furthermore, the clamping mechanism includes a chassis and a telescopic cylinder, the outer wall of the chassis is rotatably connected to an adjusting disk, the outer wall of the adjusting disk is provided with a plurality of limit grooves, the outer wall of the adjusting disk is fixedly connected to a plurality of limit blocks, an adjusting slider is arranged between every two of the limit blocks, the outer wall of each adjusting slider is movably connected to a sliding rod, the outer wall of each adjusting slider is fixedly connected to an opening and closing support foot, the bottom of the chassis and the telescopic cylinder are fixedly connected to the upper surface of the movable base, the outer wall of the adjusting disk is rotatably connected to a hinge, the outer wall of the hinge is fixedly connected to the output end of the telescopic cylinder, the outer wall of each adjusting slider is slidably connected to the outer wall of the limit block, and the outer wall of each sliding rod is slidably connected to the outer wall of its corresponding limit groove.

[0012] The above technical solution is adopted to adjust the opening and closing legs. The output end of the telescopic cylinder is telescopically extended to drive the adjusting disk to rotate, and drive the sliding rod to slide in the limit groove, so that the opening and closing legs are gathered first, extended into the heat shrinkable sleeve and then dispersed. When the heat shrinkable sleeve is tensioned, it stops, and the sleeve port is fixed at this time.

[0013] Furthermore, the outer wall of the ring rail is fixedly connected to the outer wall of the support frame, the outer wall of the support frame is fixedly connected with a waste collection box and a peeling piece, and the bottom of the support frame and the waste collection box are both fixedly connected to the upper surface of the fixed base.

[0014] By adopting the above technical solution, the peeling piece can remove the waste material from the opening and closing support legs. After cutting, the cut heat shrink tubing still remains on the opening and closing support legs. The driving motor rotates in the opposite direction to drive the movable base to move backward, and then drives the clamping mechanism to move backward. When the opening and closing support legs withdraw from the leveling mechanism, the peeling piece will remove the heat shrink tubing remaining on the opening and closing support legs and drop it into the waste collection box below.

[0015] Furthermore, the outer wall of the sliding bin is slidably connected to the inner wall of the sawtooth ring, the inner wall of the sawtooth ring is provided with a plurality of strip-shaped teeth, and the outer wall of the roller is meshed with the strip-shaped teeth of the sawtooth ring.

[0016] By adopting the above technical scheme, the sliding chamber can slide between the two serrated rings. The output shafts at both ends of the double-headed rotating motor rotate to drive the driving assembly to rotate. The roller makes a circular motion with the output shaft of the double-headed rotating motor as the axis and meshes with the strip teeth of the serrated ring, thereby driving the sliding chamber to make a circular motion between the two serrated rings with the center of the serrated ring as the center.

[0017] Furthermore, the rotary cylinder is fixedly mounted on the inner wall of the sliding compartment, and the drive shaft passes through the fixed housing and is fixedly connected to the output shaft of the rotary cylinder.

[0018] The above technical solution is adopted to drive the driving shaft to rotate. The output shaft of the rotating cylinder drives the driving shaft to rotate, and the driving shaft drives the driving gear to rotate synchronously. The driving gear meshes with the driven gear to rotate, driving the U-shaped connecting piece to move up and down.

[0019] Furthermore, the telescopic rod passes through a limiting ring and is fixedly connected to an outer wall of the telescopic inner shell, and the outer wall of the telescopic rod is slidably connected to an inner wall of the limiting ring.

[0020] The above technical solution plays a role in limiting the telescopic rod. The U-shaped connecting piece moves up and down to drive the telescopic rod to move up and down in the limiting ring, and the telescopic inner shell moves synchronously with it.

[0021] Furthermore, the outer wall of the telescopic inner shell is symmetrically fixedly connected with a telescopic outer tube, the interiors of the two telescopic outer tubes are provided with telescopic elastic parts, the inner walls of the two telescopic outer tubes are slidably connected with the telescopic inner tube, and a circular cutting blade is provided between the two telescopic inner tubes and is rotatably connected thereto.

[0022] By adopting the above technical scheme, the effect of the circular cutting blade pressing the heat shrinkable sleeve is achieved, making the cutting more complete. When the circular cutting blade presses the heat shrinkable sleeve, the rotating cylinder stops running. At this time, the optimal cutting distance of the circular cutting blade is achieved. The setting of the telescopic elastic part can make the circular cutting blade fit tightly against the outer wall of the heat shrinkable sleeve.

[0023] The present invention has the following beneficial effects:

[0024] (1) The present invention drives the driving shaft to rotate by rotating the cylinder, and the driving shaft drives the driving gear to rotate synchronously, and the driving gear meshes with the driven gear to rotate, thereby driving the U-shaped connecting piece to move up and down, and then driving the telescopic rod to move up and down in the limit ring, and the telescopic inner shell moves synchronously with it. When the circular cutting blade presses the heat shrinkable sleeve, the rotating cylinder stops running, and the optimal cutting distance of the circular cutting blade is achieved. The setting of the telescopic elastic member can make the circular cutting blade fit tightly with the outer wall of the heat shrinkable sleeve, so that the cutting is more complete.

[0025] (2) The present invention uses a circular cutting blade to make a circular cut on the heat shrink tube to achieve leveling of its end. After the cutting is completed, the cut heat shrink tube still remains on the opening and closing legs. The driving motor rotates in the opposite direction to drive the movable base to move backward, and then drives the clamping mechanism to move backward. When the opening and closing legs withdraw from the leveling mechanism, the peeling piece will peel off the heat shrink tube remaining on the opening and closing legs and drop it into the waste collection box below, thereby recycling the waste.

[0026] (3) The present invention drives the screw to rotate through the output shaft of the driving motor, and the rotation of the screw drives the movable base to move horizontally, so that the clamping mechanism is moved in front of the casing transmission device. At this time, one of the telescopic plates slides into the fixed base, and the other telescopic plate slides and stretches on the fixed plate, so that the equipment cabin is always in a closed state, avoiding dust generated by cutting or cut casing from falling into the equipment cabin, reducing excessive wear of various parts in the equipment, and extending the service life of the parts.

[0027] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
