Description

Technical Field

[0001] This invention belongs to the technical field of grinding devices, and specifically relates to a die grinding device. Background Technology

[0002] An extrusion die is a mold used to produce plastic profiles with continuous shapes. It's an extrusion process where pressure forces material through the die to form the product. During processing, powdered or granular polymer is typically added to the extruder barrel. Under the action of the screw or plunger, the polymer moves forward along the screw channel or barrel, gradually melting into a viscous fluid. This fluid then passes through the die at the end of the barrel, forming a continuous body similar in shape to the die's orifice. After cooling and solidification, the desired product shape is formed. To ensure the stability of extrusion production and the quality of the extruded product, the die structure is crucial. The die lip is a key aspect of quality assurance. Die lip grinding processes maintain the die lip in good working condition, preventing extrusion failures and lower quality products. A good die lip condition improves both the quality of the extruded product and production efficiency.

[0003] After a period of operation, the die lip surface will wear down, requiring grinding. Patent CN204221567U discloses a semi-automatic grinding machine, including a linear guide assembly and a grinding assembly. The linear guide assembly includes a motor and a fixed block, with a lead screw movably connected between the motor and the fixed block. A matching threaded movable block passes through the lead screw. A fixed plate, a thick washer, and a spring are bolted to the bottom of the threaded movable block from top to bottom. The grinding assembly includes a grinding block and a set screw. The upper end of the grinding block is fixedly connected to the spring, and the set screw passes through the fixed plate and presses against the surface of the spring at the upper end of the grinding block. This device is easy to install, greatly facilitating daily maintenance and timely repair of minor defects of the die head, while also avoiding the impact of manual operation on grinding accuracy. However, this device requires manual application and replacement of grinding paste during the grinding process. Furthermore, it can only grind the horizontal die lip of the die head and cannot grind the vertical die lip. If the vertical die lip needs to be ground, the die head needs to be manually changed to fix its direction. Moreover, the die head grinding requires three grinding operations with different precisions. The device requires manual replacement of grinding cloths with different precisions and multiple adjustments to the position of the grinding tools to complete the grinding of the entire die lip. This process is labor-intensive and time-consuming, which is not conducive to improving production efficiency.

[0004] Therefore, it is of great significance to develop a grinding device that can complete the grinding of different lip of the die head without having to manually adjust the grinding device multiple times. Summary of the Invention

[0052] The working process of the grinding apparatus of the present invention is as follows:

[0053] (1) Manually assemble the mold head onto the mold head transport plate, push the mold head transport plate along the track to the fixed slot position for fixing. A sensor is installed in the fixed slot. After the mold head transport plate moves to the fixed slot position, the sensor sends a signal to the PLC, and the PLC sends a start signal 1 to the motor C.

[0054] (2) After receiving the start signal 1, motor C adjusts the grinding head through the program set by PLC, adjusts the grinding head to the working surface, and after reaching the working position, PLC sends control signal 1 to the position detector;

[0055] (3) After receiving control signal 1, the position detector detects the position information of the horizontal die lip and sends it to the PLC;

[0056] (4) After receiving the position information of the horizontal mold lip, the PLC sends control signal 2 to motor A, motor B and hydraulic rod;

[0057] (5) After receiving control signal 2, motor A, motor B and hydraulic rod move, move the grinding head to the grinding starting point and the rectangular grinding surface a is in contact with the horizontal mold lip, and then the hydraulic rod stops moving (during this process, the pressure sensor monitors the pressure and sends it to the PLC, the PLC compares the monitored pressure with the set pressure range, and sends a stop signal to the hydraulic rod when the monitored pressure is equal to the set pressure); after motor A, motor B and hydraulic rod stop moving, the PLC sends start signal 2 to the piston rod connected to the piston rod of the first grinding liquid container A to drive the motor, and at the same time sends control signal 3 to motor B;

[0058] (6) After receiving the start signal 2, the piston rod drive motor connected to the piston rod of the first grinding fluid container A drives the piston rod to move, so that the grinding fluid flows out from the first grinding fluid outlet A;

[0059] After receiving control signal 3, motor B controls the grinding head to reciprocate in the left and right direction. During this process, the roughness meter monitors the roughness of the die head surface and sends it to the PLC. The PLC compares the roughness with the set roughness range. When the detected roughness is within the set roughness range, it sends stop signal 1 to the piston rod drive motor connected to the piston rod of the first grinding fluid container A and sends start signal 3 to the hydraulic rod and motor C.

[0060] (7) After receiving the start signal 3, the hydraulic rod and motor C adjust the grinding head through the program set by the PLC. The hydraulic rod first adjusts the grinding head upward to a suitable distance, and then the motor C adjusts the grinding head to the working surface of the rectangular grinding surface b. After reaching the working position, the PLC sends the control signal 4 to the position detector.

[0061] (8) After receiving control signal 4, the position detector detects the position of the horizontal membrane lip and sends it to the PLC;

[0062] (9) After receiving the position of the horizontal mold lip, the PLC sends start signal 4 to motor A, motor B and hydraulic rod;

[0063] (10) After receiving the start signal 4, motor A, motor B and hydraulic rod move. Motor B first controls the grinding head to move in the horizontal direction until the grinding head moves to the grinding starting point and the rectangular grinding surface b is in contact with the horizontal mold lip. Then, motor A, motor B and hydraulic rod stop moving. At the same time, PLC sends start signal 5 to the piston rod connected to the piston rod of the second grinding liquid container A to drive the motor, and sends control signal 5 to motor B.

[0064] (11) After receiving the start signal 5, the piston rod drive motor connected to the piston rod of the second grinding fluid container A drives the piston rod to move, so that the grinding fluid flows out from the second grinding fluid outlet A;

[0065] After receiving control signal 5, motor B controls the grinding head to reciprocate in the left and right direction. During this process, the roughness meter monitors the roughness of the die head surface and sends it to the PLC. The PLC compares the real-time roughness with the set roughness range. When the roughness is within the set roughness range, it sends stop signal 2 to the piston rod drive motor connected to the piston rod of the second grinding fluid container A and sends start signal 6 to motor C.

[0066] (12) After receiving the start signal 6, the motor C adjusts the grinding head through the program set by the PLC. The motor C then adjusts the grinding head to the working surface of the rectangular grinding surface c. After reaching the working position, the PLC sends the control signal 6 to the position detector. After receiving the control signal 6, the position detector detects the position of the horizontal lip and sends it to the PLC.

[0067] (13) After receiving the position of the horizontal diaphragm lip, the PLC sends start signal 7 to motor A, motor B and hydraulic rod;

[0068] (14) Motor A, Motor B and hydraulic rod move after receiving start signal 7. Motor B first controls the grinding head to move in the horizontal direction until the grinding head moves to the grinding starting point and the rectangular grinding surface c is in contact with the horizontal mold lip. Then the hydraulic rod stops moving. PLC sends start signal 8 to the piston rod connected to the piston rod of the third grinding liquid container A to drive the motor, and at the same time sends control signal 7 to motor B.

[0069] (15) After receiving the start signal 8, the piston rod drive motor connected to the piston rod of the third grinding fluid container A drives the piston rod to move, so that the grinding fluid flows out from the third grinding fluid outlet A;

[0070] After receiving control signal 7, motor B controls the grinding head to reciprocate in the left and right direction. During this process, the roughness meter monitors the roughness of the die head surface in real time and sends it to the PLC. The PLC compares the real-time roughness with the set roughness. When the real-time roughness is equal to the set roughness, it sends stop signal 3 to the piston rod drive motor connected to the piston rod of the third grinding fluid container A, and at the same time sends control signal 8 to the hydraulic rod and position detector.

[0071] (16) After receiving control signal 8, the hydraulic rod first adjusts the grinding head upward to a suitable distance, and the position detector detects the position information of the vertical die lip and sends it to the PLC;

[0072] (17) After receiving the position of the vertical die lip, the PLC sends control signal 9 to motor A, motor B and hydraulic rod;

[0073] (18) After receiving control signal 9, motor A, motor B and hydraulic rod move in the horizontal and vertical directions until the grinding head moves to the grinding starting point and the vertical grinding surface I is in contact with the vertical mold lip. After that, motor A, motor B and hydraulic rod stop moving. PLC sends start signal 9 to the piston rod connected to the piston rod of the first grinding liquid container B to drive the motor, and at the same time sends control signal 10 to motor B.

[0074] (19) After receiving the start signal 9, the piston rod drive motor connected to the piston rod of the first grinding fluid container B drives the piston rod to move, so that the grinding fluid flows out from the first grinding fluid outlet B;

[0075] After receiving control signal 10, motor B controls the grinding head to reciprocate in the left and right direction. During this process, the roughness meter monitors the roughness of the die head surface and sends it to the PLC. The PLC compares the roughness with the set roughness range. When the measured roughness is within the set roughness range, it sends stop signal 4 to the piston rod connected to the piston rod of the first grinding fluid container B, which drives the motor and motor B. At the same time, it sends control signal 11 to the hydraulic rod and position detector.

[0076] (20) After receiving control signal 11, the position detector detects the position information of the vertical die lip and sends it to the PLC;

[0077] (21) After receiving the position of the vertical die lip, the PLC sends control signal 12 to motor A, motor B and hydraulic rod;

[0078] 45 (22) After receiving control signal 12, motor A, motor B and hydraulic rod move in the horizontal and vertical directions until the grinding head moves to the grinding starting point and the vertical grinding surface II is in contact with the vertical mold lip. After motor A, motor B and hydraulic rod stop moving, PLC sends start signal 10 to the piston rod connected to the piston rod of the second grinding liquid container B to drive the motor, and at the same time sends control signal 13 to motor B.

[0079] (23) After receiving the start signal 10, the piston rod drive motor connected to the piston rod of the second grinding fluid container B drives the piston rod to move, so that the grinding fluid flows out from the second grinding fluid outlet B;

[0080] After receiving control signal 13, motor B controls the grinding head to reciprocate in the left and right direction. During this process, the roughness meter monitors the roughness of the die head surface and sends it to the PLC. The PLC compares the roughness with the set roughness range. When the roughness is within the set roughness range, it sends stop signal 5 to the piston rod connected to the piston rod of the second grinding fluid container B, which drives the piston rod motor and motor B. At the same time, it sends control signal 14 to the hydraulic rod and position detector.

[0081] (24) After receiving control signal 14, the hydraulic rod and position detector detect the position information of the vertical die lip and send it to the PLC;

[0082] (25) After receiving the position of the vertical die lip, the PLC sends control signal 15 to motor A, motor B and hydraulic rod;

[0083] (26) After receiving control signal 15, motor A, motor B and hydraulic rod move in the horizontal and vertical directions, move the grinding head to the grinding starting point and the vertical grinding surface III is in contact with the vertical mold lip. After motor A, motor B and hydraulic rod stop moving, PLC sends start signal 11 to the piston rod connected to the piston rod of the third grinding liquid container B to drive the motor, and at the same time sends control signal 16 to motor B.

[0084] (27) After receiving the start signal 11, the piston rod drive motor connected to the piston rod of the third grinding fluid container B drives the piston rod to move, so that the grinding fluid flows out from the third grinding fluid outlet B;

[0085] After receiving control signal 16, motor B controls the grinding head to reciprocate in the left and right direction. During this process, the roughness meter monitors the roughness of the die head surface and sends it to the PLC. The PLC compares the roughness with the set roughness range. When the roughness is within the set roughness range, it sends stop signal 6 to the piston rod connected to the piston rod of the third grinding fluid container B to drive the motor, and sends control signal 17 to motor B and hydraulic rod.

[0086] (28) After receiving control signal 17, motor B and hydraulic rod are reset to complete the grinding.

[0087] All polishing slurries consist of polishing paste and silicone oil. The polishing paste flowing out of different polishing slurries is different in order to achieve polishing processes of different precision.

[0088] Beneficial effects:

[0089] The die head grinding device of the present invention can switch between horizontal grinding surfaces with different roughness by rotating, so as to achieve grinding of the die lip with different precision. This process does not require manual replacement, reduces grinding steps, reduces time investment, and improves work efficiency.

[0090] The die head grinding device of the present invention can adjust the grinding position of the die head by moving the beam, so as to meet the position requirements of grinding the lip of various types of die heads, which is convenient and practical. Attached Figure Description
