Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive labeling machines, and specifically to a blade mounting symmetry detection and adjustment device for hot melt adhesive labeling machines. Background Technology

[0002] The blades in the hot melt adhesive labeling machine are installed on the blade plate in the blade mounting seat. After the blades are installed, it is necessary to check and adjust the installation symmetry at both ends. The traditional detection and adjustment method is relatively complicated, requiring multiple manual calibrations, which requires high technical skills from the operators and is inefficient. In addition, the detection tools are not accurate enough, with cumulative errors exceeding 0.02mm. They are sensitive to the installation symmetry of the blades and can easily lead to a shortened blade life. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a blade mounting symmetry detection and adjustment device that can improve detection accuracy, improve detection and adjustment efficiency, simplify operation, reduce reliance on manual skills, and reduce manufacturing costs.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: a blade mounting symmetry detection and adjustment device, characterized in that it includes: two dial indicators, a calibration base, and a detection bracket. The detection bracket structure includes: a strip-shaped beam, with a vertically downward-facing support foot at each end of the strip-shaped beam. The two support feet and the strip-shaped beam are arranged in a U-shape. A locking block is provided at the bottom of each of the two support feet, and a mounting hole is provided on each of the two support feet. Each mounting hole vertically penetrates the support foot and the locking block. The two dial indicators are vertically mounted at the left and right ends of the strip-shaped beam with adjustable height. The detection heads of the two dial indicators pass downward through the strip-shaped beam and are located between the two support feet. The calibration base structure includes: a strip-shaped base, with a mounting step provided on the upper surface of each end of the strip-shaped base. A threaded hole is provided on each of the two mounting steps. A calibration boss is provided on the upper part of the strip-shaped base, and a reference surface is machined on the top of the calibration boss. The two support feet of the detection bracket can be placed on the two mounting feet respectively. On the step, two long bolts can pass through two mounting holes and be screwed into two threaded holes respectively, so that the test bracket can be fixed on the calibration base. At this time, the strip beam on the test bracket can be parallel to the reference surface on the calibration boss. After adjusting the height of the two dial indicators, the measuring heads of the two dial indicators can abut against the reference surface respectively, so that the reference surface can be used as the reference for resetting and zeroing the dial indicators. There are also two fine adjustment knobs installed at both ends of the blade mounting base for adjusting the extension distance of the two ends of the blade. Each fine adjustment knob is equipped with a set of meshing gears and racks installed in the blade mounting base. The fine adjustment knob is used to drive the gear to rotate. The rack is slidably installed in the blade mounting base. The outer end of the rack is fixed to the blade plate in the blade mounting base. The blade is installed on the blade plate. After turning the fine adjustment knob, the rack can move the blade plate in and out under the drive of the gear, thereby adjusting the extension distance of the two ends of the blade. After the installation symmetry of the two ends of the blade is adjusted, it can be locked by the screws threaded to the blade mounting base.

[0005] Furthermore, the aforementioned blade is equipped with a symmetry detection and adjustment device, wherein a handle is installed on the middle of the upper surface of the strip beam.

[0006] Furthermore, the aforementioned blade mounting symmetry detection and adjustment device includes the following mounting structure for the dial indicator and the strip beam: a vertical through hole is provided on the strip beam, the dial indicator is inserted into the vertical through hole, a notch is provided on the strip beam, and a clamp is provided in the notch. The clamp is located above the vertical through hole, half of the clamp is part of the strip beam, and the other half of the clamp is located in the notch. The locking screw of the clamp can pass through the notch and be screwed into the clamp, and the clamp can lock the dial indicator inserted into the vertical through hole.

[0007] Furthermore, the aforementioned blade mounting symmetry detection and adjustment device includes a strip-shaped base with several weight-reduction holes arranged along the strip-shaped base.

[0008] Furthermore, the aforementioned blade mounting symmetry detection and adjustment device includes a detection bracket made of lightweight aluminum alloy.

[0009] The advantages of this utility model are as follows: the blade installation symmetry detection and adjustment device uses two dial indicators for symmetrical detection, and the two dial indicators are uniformly zeroed, thereby reducing the cumulative error from the traditional >0.02mm to within 0.01mm, so that the blade installation symmetry deviation can be adjusted to ≤0.005mm. This can extend the blade life by 30%, reduce the reliance on manual skills, and reduce the detection time by 70% and improve the efficiency of manual operation by 40% by adopting a quick installation design and calibration function. It simplifies the operation process, optimizes the cost structure, and the modular design also reduces manufacturing costs and maintenance difficulty. Attached Figure Description

[0013] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0014] like Figure 1 , Figure 2 , Figure 3As shown, the blade mounting symmetry detection and adjustment device includes: two dial indicators 1, a calibration base 2, and a detection bracket 3. The detection bracket 3 consists of: a strip-shaped beam 4, with a vertically downward-facing support leg 5 at each end of the strip-shaped beam 4. The two support legs 5 and the strip-shaped beam 4 are arranged in a U-shape. A locking block 6 is provided at the bottom of each of the two support legs 5, and a mounting hole is provided on each of the two support legs 5. Each mounting hole vertically penetrates the support leg 5 and the locking block 6. The two dial indicators 1 are vertically mounted at adjustable height on the left and right ends of the strip-shaped beam 4. The two dial indicators 1 and the strip-shaped beam 4 are connected in a U-shape. The crossbeam 4 is perpendicular to the two micrometers 1. The measuring heads of the two micrometers 1 pass downward through the crossbeam 4 and are located between the two support legs 5. The structure of the calibration base 2 includes: a strip-shaped base 7, with a mounting step 8 on each of the two upper surfaces of the strip-shaped base 7, a threaded hole 9 on each of the two mounting steps 8, a calibration boss 10 on the upper part of the strip-shaped base 7, and a reference surface 11 machined on the top of the calibration boss 10. The two support legs 5 of the measuring bracket 3 can be placed on the two mounting steps 8 respectively, and the two long bolts 12 can pass through the two mounting holes and be screwed into the two mounting legs 5 respectively. In the threaded hole 9, the test bracket 3 can be fixed on the calibration base 2. At this time, the strip beam 4 on the test bracket 3 can be parallel to the reference surface 11 on the calibration boss 10. After adjusting the height of the two dial indicators 1, the measuring heads of the two dial indicators 1 can abut against the reference surface 11 respectively, so that the reference surface 11 can be used as the reference for resetting and zeroing the dial indicator 1. The surface of the reference surface 11 is finely ground, and the flatness error is ≤0.005mm. The test bracket 3 is made of lightweight aluminum alloy. It is also provided with two parts installed at both ends of the blade mounting seat 18 for adjusting the extension of the two ends of the blade 19. The distance fine-tuning knob 13 is equipped with a set of meshing gears and racks installed in the blade mounting seat 18. The fine-tuning knob 13 is used to drive the gears to rotate. The rack is slidably installed in the blade mounting seat 18. The outer end of the rack is fixed to the blade plate in the blade mounting seat 18. The blade 19 is installed on the blade plate. After turning the fine-tuning knob 13, the rack can move the blade plate in and out under the drive of the gear, thereby adjusting the extension distance at both ends of the blade. After the installation symmetry of the two ends of the blade 19 is adjusted, it can be locked by the screws threaded to the blade mounting seat 18.

[0015] In this embodiment, a handle 14 is installed on the middle of the upper surface of the strip beam 4. The mounting structure of the dial indicator 1 and the strip beam 4 is as follows: a vertical through hole is provided on the strip beam 4, the dial indicator 1 is inserted into the vertical through hole, a notch 15 is provided on the strip beam 4, and a clamp 16 is provided in the notch 15. The clamp 16 is located above the vertical through hole, half of the clamp 16 is part of the strip beam 4, and the other half of the clamp 16 is located in the notch 15. The locking screw of the clamp 16 can pass through the notch 15 and be screwed into the clamp 16, so that the clamp 16 can lock the dial indicator 1 inserted in the vertical through hole. Five weight-reducing holes 17 are provided on the strip base 7.

[0016] Different calibration bases 2 are required for installing and adjusting different blades. Because the distance of the blade exposed after different blades are installed is different, the height of the reference surface 11 on different calibration bases 2 is also different to adapt to the corresponding stationary blade.

[0017] During operation, lock the test bracket 3 onto the calibration base 2, then adjust the height of the two dial indicators 1 so that the test heads of the two dial indicators 1 press against the reference surface 11 on the calibration base 2. Next, use the reference surface 11 as the reference for resetting and zeroing the dial indicators 1. Then, use the handle 14 to move the test bracket 3 next to the blade mounting seat 18, and then remove the test bracket 3 from the calibration base 2. Figure 3 As shown, the test bracket 3 is tightened onto the blade mounting base 18 with screws, so that the test bracket 3 is aligned with the blade 19. The test heads of the two dial indicators 1 are pressed on the blade edge of the blade 19. The height and symmetry of the blade 19 are monitored in real time by the two dial indicators 1. Then, the fine adjustment knob 13 is manually turned according to the scale of the two dial indicators 1 to dynamically fine adjust the extension distance of the two ends of the blade 19 until the installation symmetry deviation of the blade 19 is ≤0.005mm. After the adjustment is completed, the test bracket 3 is removed from the blade mounting base 18.
