Description

Technical Field

[0001] This invention relates to the field of extrusion die technology, and in particular to a dual-group intelligent adjuster for extrusion dies. Background Technology

[0002] The die lip opening gap on the extrusion die head usually needs to be adjusted by a fine-tuning screw. Initially, conventional adjusters could only adjust the fine-tuning screw, which had certain limitations on die heads containing baffles. The adjustment of the baffles still required manual adjustment and could not achieve complete automation. Summary of the Invention

[0003] To address the aforementioned problems, this invention aims to provide a dual-group intelligent adjuster for extrusion dies. This novel adjuster utilizes an industrial vision system and multiple motors to simultaneously adjust the fine-tuning screws and flow-restricting bars online.

[0004] The technical solution of this invention is a dual-group intelligent adjuster for an extrusion die, comprising an extrusion die and an adjuster body arranged in parallel. The front region of the extrusion die has a series of fine-tuning screws in the front row and a series of flow-blocking bars in the rear row, evenly arranged along the width direction. The adjuster body is connected to the extrusion die via a bracket. The adjuster body is characterized by having a first rack and a first guide rail arranged along the width direction on its front side. A main mounting plate is slidably connected to the first guide rail via a first slider. A first motor is connected to the main mounting plate, and the output shaft of the first motor meshes with the first rack via a first transmission gear. The first motor drives the main mounting plate to move laterally along the first guide rail via a gear and rack mechanism. The main mounting plate is equipped with an industrial vision system, an automatic flow-blocking bar adjustment mechanism, and an automatic fine-tuning screw adjustment mechanism. The industrial vision system captures the position of the flow-blocking bars and feeds it back to the automatic flow-blocking bar adjustment mechanism for fine-tuning. The industrial vision system also captures the position of the fine-tuning screws and feeds it back to the automatic fine-tuning screw adjustment mechanism for fine-tuning.

[0005] Preferably, the automatic adjustment mechanism for the flow-restricting bar includes a second guide rail vertically mounted on the main mounting plate. A second motor mounting plate is connected to the second guide rail via a slider. A second rack and a second motor are vertically mounted on the second motor mounting plate. A flow-restricting bar bit is synchronously connected to the lower end of the output shaft of the second motor. A third motor is mounted on the main mounting plate. The output shaft of the third motor meshes with the second rack via a second transmission gear. The third motor drives the second motor mounting plate to move vertically up and down along the second guide rail via a gear and rack mechanism. The industrial vision system captures the position of the flow-restricting bar and, through the coordinated operation of the first, second, and third motors, ultimately performs rotational fine-tuning of the flow-restricting bar using the flow-restricting bar bit.

[0006] Preferably, the top of the flow-blocking rod has an external hexagonal structure and each corner is provided with a flow-blocking rod calibration point. The industrial vision system controls the rotation of the flow-blocking rod bit by capturing the flow-blocking rod calibration points and then aligns it with the top of the flow-blocking rod.

[0007] Preferably, the automatic adjustment mechanism for the fine-tuning screw includes a third guide rail vertically mounted on the main mounting plate. A fourth motor mounting plate is slidably connected to the third guide rail via a slider. A third rack and a fourth motor are vertically mounted on the fourth motor mounting plate. A fine-tuning screwdriver bit is synchronously connected to the lower end of the output shaft of the fourth motor. A fifth motor is mounted on the main mounting plate. The output shaft of the fifth motor meshes with the third rack via a third transmission gear. The fifth motor drives the fourth motor mounting plate to move vertically up and down along the third guide rail via a gear and rack mechanism. The industrial vision system captures the position of the fine-tuning screw and, through the coordinated operation of the first, fourth, and fifth motors, ultimately performs rotational fine-tuning of the fine-tuning screw using the fine-tuning screwdriver bit.

[0008] Preferably, the tip of the fine-tuning screw has an external hexagonal structure and each corner is provided with a fine-tuning screw calibration point. The industrial vision system controls the fine-tuning screw bit to rotate and align with the tip of the fine-tuning screw by capturing the fine-tuning screw calibration points.

[0009] Preferably, the width of the regulator body is greater than the width of the extrusion die.

[0010] Preferably, during the lateral movement of the main mounting plate, the axis of the flow-blocking bar bit is located on the straight line formed by the axes of the entire row of flow-blocking bars; during the lateral movement of the main mounting plate, the axis of the fine-tuning screwdriver bit is located on the straight line formed by the axes of the entire row of fine-tuning screws.

[0011] Preferably, the industrial vision system consists of two sets, one set for capturing flow-blocking bars and the other set for capturing fine-tuning screws.

[0012] This invention achieves simultaneous online adjustment of fine-tuning screws and flow-restricting bars by setting up an industrial vision system in conjunction with the linkage of multiple motors. Attached Figure Description

Detailed Implementation

[0014] The present invention will now be described in further detail with reference to the accompanying drawings.

[0015] like Figures 1 to 6 As shown, this invention provides a dual-group intelligent regulator for extrusion dies, comprising an extrusion die 1 and a regulator body 2 arranged in parallel. The front region of the extrusion die 1 has a series of fine-tuning screws 3 arranged in the front row and a series of flow-blocking rods 4 arranged in the rear row, all uniformly arranged along the width direction. The regulator body 2 is connected to the extrusion die 1 via a bracket. The regulator body 2 is characterized by having a first rack 5 and a first guide rail 6 arranged along the width direction on its front side. A main mounting plate 8 is slidably connected to the first guide rail 6 via a first slider 7. A first motor 9 is connected to the main mounting plate 8. The output shaft of the first motor 9 meshes with the first rack 5 through the first transmission gear 10. The first motor 9 drives the main mounting plate 8 to move laterally along the first guide rail 6 through the gear and rack mechanism. The main mounting plate 8 is equipped with an industrial vision system 11, an automatic adjustment mechanism 12 for the flow-blocking bar, and an automatic adjustment mechanism 13 for the fine-tuning screw. After the industrial vision system 11 captures the position of the flow-blocking bar 4, it feeds back to the automatic adjustment mechanism 12 for fine-tuning the flow-blocking bar 4. After the industrial vision system 11 captures the position of the fine-tuning screw 3, it feeds back to the automatic adjustment mechanism 13 for fine-tuning the fine-tuning screw 3.

[0016] Specifically, the automatic adjustment mechanism 12 for the flow-restricting bar includes a second guide rail vertically mounted on the main mounting plate 8. A second motor mounting plate 122 is connected to the second guide rail via a slider. A second rack 123 and a second motor 124 are vertically mounted on the second motor mounting plate 122. A flow-restricting bar bit 125 is synchronously connected to the lower end of the output shaft of the second motor 124. A third motor 126 is mounted on the main mounting plate 8. The output shaft of the third motor 126 meshes with the second rack 123 via a second transmission gear 127. The third motor 126 drives the second motor mounting plate 122 to move vertically up and down along the second guide rail via a gear and rack mechanism. The industrial vision system 11 captures the position of the flow-restricting bar 4 and, through the coordinated operation of the first motor 9, the second motor 124, and the third motor 126, ultimately performs rotational fine-tuning of the flow-restricting bar 4 via the flow-restricting bar bit 125.

[0017] Specifically, the top of the flow-blocking rod 4 has an external hexagonal structure and each corner is provided with a flow-blocking rod calibration point 41. The industrial vision system 11 controls the flow-blocking rod bit 125 to rotate and align with the top of the flow-blocking rod 4 by capturing the flow-blocking rod calibration point 41.

[0018] Specifically, the automatic adjustment mechanism 13 for the fine-tuning screw includes a third guide rail 131 vertically mounted on the main mounting plate 8. A fourth motor mounting plate 132 is slidably connected to the third guide rail 131 via a slider. A third rack 133 and a fourth motor 134 are vertically mounted on the fourth motor mounting plate 132. A fine-tuning screwdriver bit 135 is synchronously connected to the lower end of the output shaft of the fourth motor 134. A fifth motor 136 is mounted on the main mounting plate 8. The output shaft of the fifth motor 136 meshes with the third rack 133 via a third transmission gear 137. The fifth motor 136 drives the fourth motor mounting plate 132 to move vertically up and down along the third guide rail 131 via a gear and rack mechanism. The industrial vision system 11 captures the position of the fine-tuning screw 3 and, through the coordinated operation of the first motor 9, the fourth motor 134, and the fifth motor 136, ultimately performs rotational fine-tuning of the fine-tuning screw 3 via the fine-tuning screwdriver bit 135.

[0019] Specifically, the top of the fine-tuning screw 3 has an external hexagonal structure and each corner point is provided with a fine-tuning screw calibration point 31. The industrial vision system 11 controls the fine-tuning screw bit 135 to rotate and align with the top of the fine-tuning screw 3 by capturing the fine-tuning screw calibration point 31.

[0020] Specifically, the width of the regulator body 2 is greater than the width of the extrusion die 1.

[0021] Specifically, during the lateral movement of the main mounting plate 8, the axis of the flow-blocking bar bit 125 is located on the straight line formed by the axes of the entire row of flow-blocking bars 4; during the lateral movement of the main mounting plate 8, the axis of the fine-tuning screw bit 135 is located on the straight line formed by the axes of the entire row of fine-tuning screws 3.

[0022] Specifically, the industrial vision system 11 consists of two sets, one set corresponding to capturing the flow-blocking bar 4, and the other set corresponding to capturing the fine-tuning screw 3.

[0023] In this invention, the industrial vision system 11 captures the calibration point 31 on the top of the fine-tuning screw 3, determines the angle, direction and position, controls the first motor 9 to adjust the lateral position, and after the main mounting plate 8 moves to the fine-tuning screw 3 that needs to be adjusted, the fifth motor 136 controls the fourth motor mounting plate 132 to move vertically up and down along the third guide rail 131 through the gear and rack mechanism, inserts the fine-tuning screw bit 135 into the top of the fine-tuning screw 3, and finally rotates the fourth motor 134 to turn the fine-tuning screw 3, thereby realizing the fine adjustment of the mold lip opening gap at that location.

[0024] Similarly, when fine-tuning the flow-restricting bar 4, the industrial vision system 11 captures the calibration point 41 on the top of the flow-restricting bar 4, determines the angle, direction and position, controls the first motor 9 to adjust the lateral position, and after the main mounting plate 8 moves to the flow-restricting bar 4 that needs to be adjusted, it controls the third motor 126 to drive the second motor mounting plate 122 to rise and fall vertically along the second guide rail through the gear and rack mechanism, inserts the flow-restricting bar bit 125 into the top of the flow-restricting bar 4, and finally rotates the second motor 124 to turn the flow-restricting bar 4, thereby achieving fine-tuning of the mold lip opening gap at that location.

[0025] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention in any way. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present invention shall still fall within the scope of the technical solution of the present invention.
