Description

Technical Field

[0001] This invention relates to the field of ABS plastic sheet trimming equipment, and more particularly to an automatic ABS plastic sheet trimming machine. Background Technology

[0002] ABS sheet is a relatively new material in the sheet industry. Its full name is acrylonitrile butadiene styrene copolymer sheet. It is the polymer with the largest production volume and the most widespread application. It organically combines the various properties of PS, SAN, and BS, exhibiting excellent mechanical properties with a balance of toughness, hardness, and rigidity.

[0003] In the prior art, according to Chinese patent application number 202420847215.6, an automatic trimming machine for plastic sheets is disclosed, which includes a base. Two symmetrical fixing blocks are fixed at both ends of the top of the base. The top of each fixing block is provided with a clamping device for holding the plastic sheet. A first support column is fixed at the center of the top of the base, and a first rotating rod is rotatably connected to the top of the first support column. This invention, by incorporating an adjustment device, allows the motor to rotate when it is running. The motor drives a lead screw to rotate, which in turn drives one of the first sliders to slide. When one of the first sliders slides, a third connecting rod moves accordingly, moving within a first slot and simultaneously causing a second slider to slide on a slide rail. The rack on the outer wall of the second slider meshes with a gear, causing the gear to rotate. Simultaneously, the gear drives the first rotating rod to rotate, thus achieving angle adjustment of the plastic sheet at the top of the first rotating rod.

[0004] In the prior art, according to Chinese patent application number 202420847215.6, an automatic edge trimming machine for plastic sheets is disclosed. This machine clamps the plastic sheet at the center of its left and right sides and then trims the edges of the front and back sides. If the plastic sheet is large, the probability of wobbling on the front and back sides increases, affecting the quality of the edge trimming. Therefore, we propose an automatic edge trimming machine for ABS plastic sheets to solve the above problems. Summary of the Invention

The two A double-end electric linear slide rails 71 can move the two drive tubes 2 in different directions in the front and back directions through the C-type connecting block 72 and the B drive block 73. Adjust the distance between the two drive tubes 2 so that the drive tubes 2 can move the placement strip 17. The placement strip 17 can be located at the edge of ABS plastic sheets of different sizes, which can better support the ABS plastic sheets. At the same time, the gantry frame 12 is slidably connected to the placement platform. Through the limit plate 15, the gantry frame 12 can move together with the positioning unit 9 along with the drive tube 2. The gantry frame 12, together with the support rod 75, can support the drive tube 2 and improve the stability of the movement of the drive tube 2. Two auxiliary blocks 14 are provided on both the left and right sides of the placement plate 1. The auxiliary blocks 14 are connected to the upper side of the connecting rod 13. The auxiliary blocks 14 can position the four corners of the ABS plastic plate and, together with the placement strip 17, can better support the ABS plastic plate. The pressure plate 16 is provided with a placement strip 17 on the lower side. The placement strip 17 is connected to the upper side of the drive tube 2. The positioning unit 9 is located between the pressure plate 16 and the gantry frame 12. The positioning unit 9 allows the pressure plate 16 to move up and down.

[0025] Positioning unit 9 includes three B electric push rods 91, two C electric push rods 92, and two D electric push rods 96. The gantry frame 12 has three through holes on its upper side. The B electric push rods 91 are mounted on the upper side of the gantry frame 12, with their shaft ends passing through the through holes and connecting to the upper side of the pressure plate 16. A buffer strip 95 is connected to the lower side of the pressure plate 16. A pressure block 93 is provided on the upper side of the auxiliary block 14. The C electric push rods 92 are mounted on one side of the limiting plate 15, and the pressure block 93 is connected to the shaft ends of the C electric push rods 92.

The electric actuators 91, 92, and 96 are connected to the power supply and controller via wires. After the ABS plastic sheet is placed and limited on both sides by the limiting plate 15, the electric actuator 96 adjusts the position of the auxiliary plate 97, limiting the distance between the edge of the ABS plastic sheet and the drive tube 2. At the same time, the A adjustment processing unit 7 limits the front and back of the ABS plastic sheet and places it in a suitable position. Then, the electric actuators 91 and 92, with the pressure plate 16 and the pressure block 93 respectively, press the upper side of the ABS plastic sheet. At this time, the pressure plate 16 presses the center of the edge, and the pressure block 93 presses the four corners, which improves the stability and quality of processing.

A sliding groove is provided on one side of the C-type support strip 54 and the connecting plate 4. Sliding blocks 55 are connected to the front and rear sides of the mounting block 53, and the sliding blocks 55 can slide inside the sliding groove. An L-type connecting plate 56 is connected to the lower side of the connecting plate 4.

The A-type electric linear slide rail 51 and the C-type motor 52 are connected to a power supply and controller via wires. The ABS plastic sheet is adjusted by clamping... After the process is completed, motor C 52 will rotate the trimming cutter 11, while electric linear guide rail A 51 will move through mounting block 53 and motor C 52 to trim the edge of the ABS plastic sheet. The distance between the edge of the ABS plastic sheet and the drive tube 2 is limited by auxiliary plate 97 according to the diameter of trimming cutter 11 and the edge condition of the ABS plastic sheet. Since the four auxiliary plates 97 can be adjusted independently, the applicability of the device is improved. At the same time, when the trimming cutter 11 is processing the ABS plastic sheet, the pressure plate 16 and the pressure block 93 are in a downward pressing state, and then the auxiliary plates 97 move away from the trimming cutter 11, so as not to affect the processing of the trimming cutter 11. The two trimming cutters 11 can process both sides of the ABS plastic sheet at the same time, which improves the processing efficiency. The placement plate 1 has a placement groove at the center of the upper side. The rotating plate 3 can slide inside the placement groove. The lifting and rotating unit 8 is located between the rotating plate 3 and the C-shaped support plate 10. The lifting and rotating unit 8 can make the rotating plate 3 lift and rotate.

The shaft end of the motor 82 is connected to the inner side of the L-shaped positioning ring 84 via a rack and pinion gear meshing transmission. The electric push rod 81 and the motor 82 are connected to a power supply and a controller via wires. After the ABS plastic sheet is processed on both sides, the electric push rod 81, through the drive housing 83 and the rotating plate... 3. Lift the ABS plastic sheet to raise the pressure plate 16 and the pressure block 93, and adjust the position of the drive tube 2 and the limiting plate 15 to avoid affecting the subsequent rotation of the ABS plastic sheet. Then, motor B 82 drives the L-shaped positioning ring 84 to rotate through the ring rack and gear. The L-shaped positioning ring 84 will drive the rotating plate 3 to rotate, making the ABS plastic sheet rotate 90 degrees. Then, the ABS plastic sheet is lowered. After clamping and positioning the ABS plastic sheet, the edges are trimmed. If the size of the ABS plastic sheet is too large and the rotation diameter exceeds the maximum position limit of the drive tube 2 and the limiting plate 15, manual rotation and placement are required. The maximum position adjustment range of the drive tube 2 and the limiting plate 15 is set according to actual needs.

[0026] Operating principle: After the ABS plastic sheet is placed, adjustment unit A 6 adjusts the distance between the two corresponding limit plates 15 on the left and right. Adjustment processing unit A 7 adjusts the distance between the two corresponding limit plates 15 at the front and back by adjusting the drive tube 2, so that the four limit plates 15 clamp and position the ABS plastic sheet. Then, positioning unit 9 can limit the distance between the front and rear sides of the ABS plastic sheet and the drive tube 2, and make pressure plate 16 and pressure block 93 press down and position the ABS plastic sheet. Then, after the auxiliary plate 97 is sent, processing unit 5 in adjustment processing unit A 7 carries the trimming rotary knife 11 to trim the ABS plastic sheet. After processing, the ABS plastic sheet is released, and lifting and rotating unit 8 rotates the ABS plastic sheet 90 degrees and then clamps, positions and trims the ABS plastic sheet again.
