Description

Technical Field

[0001] The invention relates to the technical field of filter rod composite equipment, and more specifically to a suction block correction tool for a composite molding machine. Background Art

[0002] The insertion wheel is used to accurately place the filter segment group in the KDF cigarette gun in the direction of the filter rod's movement. The position accuracy of its suction slot directly affects whether the filter rod can be accurately placed in the KDF cigarette gun. At present, if the suction block position of the insertion wheel is deviated, the compound machine will malfunction and stop. To find out which suction slot is not in the right position, it is necessary to use a level to calibrate the position of each suction block. This takes a long time, has low efficiency, and is not very accurate. In addition, no special calibration tools have been found.

[0003] A Chinese patent with publication number CN111631427A disclosed on September 8, 2020 a composite filter rod conveying and docking device for a filter rod compounding machine. The scheme uses a spider-arm variable pitch adapter plate, a spider-arm changing direction adapter plate, and a linear arrangement mechanism that are connected in sequence to cooperate with each other to complete the positioning and transmission of the filter rods, and achieve stable and accurate transmission. However, due to the continuous production, it is inevitable that the components will be offset, so a correction tool is needed for quick and convenient correction of the suction block part. Summary of the invention

[0004] In order to overcome the defects described in the above-mentioned prior art, the present invention provides a composite molding machine suction block correction tooling, which can quickly correct the X-axis and Y-axis directions of the suction block in a horizontal position on the insertion wheel. Different suction blocks can be switched by rotating the insertion wheel, and the suction blocks can be checked and corrected one by one. The operation is convenient, fast and targeted.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A composite molding machine suction block correction tooling, comprising a base, a vertical adjustment block, a lateral adjustment block and a horizontal correction table, the base is provided with a vertical support rod, the end of the horizontal correction table is hinged to the top of the vertical support rod, and the hinge center axis is a horizontal rotation axis; the vertical adjustment block is located directly below the horizontal correction table and is parallel to the vertical support axis, and is used to support the horizontal correction table to correct the Y-axis accuracy of the suction block; the lateral adjustment block is arranged on the top surface of the horizontal correction table, and is used to correct the X-axis accuracy of the suction block.

[0007] Among them, the filter rod compound machine needs to be stopped in advance before detection and correction. During detection and correction, turn the insertion wheel to randomly make a suction block approximately in the horizontal position, and turn the horizontal correction table to make the suction block in the horizontal position stick to the horizontal correction table. Due to the support of the vertical adjustment block, the horizontal correction table remains horizontal. Then, observe with the naked eye whether the bottom surface of the suction block, that is, the Y-axis direction, is close to the horizontal correction table, and whether the side of the suction block, that is, the X-axis direction, is close to the horizontal adjustment block. If there is a contact gap, it means that the position of the suction block has deviated and needs to be corrected. By turning the insertion wheel to switch different suction blocks, the suction blocks are checked and corrected one by one. The entire detection and correction process is convenient and fast, more targeted, and effectively improves maintenance efficiency. The components involved in the correction and detection in the plan need to maintain a high degree of flatness and verticality to ensure sufficient correction accuracy.

[0008] As one of the preferred technical solutions, it also includes an auxiliary positioning block that is threadedly connected and fixed to the vertical adjustment block, and a positioning column is provided on the top of the auxiliary positioning block for limiting the rotation of the horizontal correction table. In order to avoid hinge deviation between the horizontal correction table and the vertical support rod, the auxiliary positioning block is added to limit the X-axis direction at the horizontal position of the horizontal correction table, avoid horizontal swing of the horizontal correction table, and ensure the correction position accuracy of the lateral adjustment block on the horizontal correction table.

[0009] As one of the preferred technical solutions, the lateral adjustment block is an L-shaped structure, one of the L-shaped surfaces is attached to the horizontal correction table and is fixed by threads. The lateral adjustment block is an L-shaped block, placed horizontally, one of the L-shaped surfaces is attached to the top surface of the horizontal correction table and is fixed by threads, and the other L-shaped surface is used to correct the X-axis direction of the air suction block.

[0010] As one of the preferred technical solutions, the L-shaped corner line of the lateral adjustment block is perpendicular to the hinge center axis. The L-shaped corner line is the intersection line at the corner of the L-shaped block.

[0011] As one of the preferred technical solutions, a positioning bolt is provided on the top of the vertical adjustment block, one end of which is threadedly engaged with the vertical adjustment block, and the other end supports the horizontal correction block. The positioning bolt abuts against the bottom of the horizontal correction block to adjust its vertical height, thereby ensuring the accuracy of the detection and correction in the Y-axis direction.

[0012] As one of the preferred technical solutions, the positioning bolt is also connected with a nut that matches it. The positioning bolt is vertically arranged, the threaded end is threadedly connected with the vertical adjustment block, the nut end abuts against the horizontal correction block, and a nut is inserted into the positioning bolt. When adjusting, the nut is tightened to lock the top surface of the vertical adjustment block, thereby preventing the positioning bolt from rotating.

[0013] As one of the preferred technical solutions, it also includes a locking bolt, and the lateral adjustment block is connected and fixed to the horizontal correction platform through the locking bolt; the auxiliary positioning block is connected and fixed to the vertical adjustment block through the locking bolt; the lateral adjustment block is correspondingly provided with a first strip hole for cooperating with the locking bolt, and the auxiliary positioning block should be provided with a second strip hole for cooperating with the locking bolt. The auxiliary positioning block and the lateral adjustment block are usually connected by at least two locking bolts, and the strip holes are mainly used to facilitate fine-tuning of the positions of the lateral adjustment block and the auxiliary positioning block.

[0014] As one preferred technical solution, the first strip hole and the second strip hole are parallel to the hinge center axis. The first strip hole and the second strip hole are used to adjust the position of the lateral adjustment block and the auxiliary positioning block in the X-axis direction.

[0015] As one of the preferred technical solutions, the vertical support rod is a telescopic rod. In order to flexibly adjust the horizontal height of the horizontal correction platform and match the vertical adjustment block, the vertical support rod adopts a telescopic rod with adjustable height.

[0016] As one of the preferred technical solutions, the horizontal correction platform is a rectangular body as a whole, and the vertical support rod and the base are a T-shaped structure as a whole. The horizontal correction platform is a rectangular body, and the lateral adjustment block is arranged on the top surface of the horizontal correction platform, and sufficient space is left on the top surface to place the suction block.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention discloses a correction tool for the suction block of a composite molding machine, which performs position correction on the suction block of the filter rod composite machine, and quickly corrects the X-axis and Y-axis directions of the suction block in a horizontal position on the insertion wheel. At the same time, different suction blocks are switched by rotating the insertion wheel to perform inspection and correction one by one, so that suction blocks with position displacement can be found in time. The operation is simple and quick, which is conducive to improving maintenance efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0026] Example

[0027] like Figure 1-3 As shown, this embodiment provides a composite molding machine suction block correction tooling, including a base 1, a vertical adjustment block 2, a lateral adjustment block 3, an auxiliary positioning block 6 and a horizontal correction table 4. Since the suction block 13 is usually made of cast iron, the tooling components use 304 stainless steel with higher hardness. At the same time, each component maintains a high flatness and verticality to ensure sufficient correction accuracy. In this embodiment, the flatness and verticality are both required to be 0.01mm.

[0028] The base 1 is provided with a vertical support rod 5, which is a T-shaped structure with the base 1 as a whole. The end of the horizontal correction platform 4 is hinged to the top of the vertical support rod 5, and the hinge center axis is a horizontal rotation axis, which is equivalent to the horizontal correction platform 4 rotating on the vertical plane around the hinge center axis. In this embodiment, the hinge rotation angle range of the horizontal correction platform is [90°, 270°].

[0029] In addition, if Figure 2As shown, the vertical adjustment block 2 is arranged parallel to the vertical support axis. In this embodiment, the vertical adjustment block 2 is also arranged on the base 1. The vertical adjustment block 2 is located directly below the horizontal position of the horizontal correction table 4 and is used to support the horizontal correction table 4 to correct the Y-axis accuracy of the suction block 13.

[0030] At the same time, the auxiliary positioning block 6 is threadedly connected and fixed to the vertical adjustment block 2, and a positioning column 7 is provided at the top of the auxiliary positioning block 6 for limiting the rotation of the horizontal correction platform 4. Figure 3 The positioning column 7 is matched with the horizontal correction platform 4 to limit the X-axis direction at the horizontal position of the horizontal correction platform 4, thereby avoiding the articulation deviation between the horizontal correction platform 4 and the vertical support rod 5, and also avoiding the horizontal swing of the horizontal correction platform 4, thereby ensuring the correction position accuracy of the lateral adjustment block 3 on the horizontal correction platform 4.

[0031] Specifically, a positioning bolt 8 is provided on the top of the vertical adjustment block 2, one end of the positioning bolt 8 is threadedly matched with the vertical adjustment block 2, and the other end supports the horizontal correction block, and the positioning bolt 8 is also connected to a nut 9 that matches it. The positioning bolt 8 is vertically arranged, and its threaded end is threadedly connected to the vertical adjustment block 2, and the nut end abuts the horizontal correction block, and its vertical height is adjusted to ensure the accuracy of the detection and correction in the Y-axis direction. In addition, a nut 9 is inserted into the positioning bolt 8, and the nut 9 is tightened during adjustment and locked on the top surface of the vertical adjustment block 2, thereby preventing the positioning bolt 8 from rotating. In this embodiment, the vertical support rod 5 is a telescopic rod with adjustable height, which can flexibly adjust the horizontal height of the horizontal correction platform 4, and also match the height adjustment of the positioning bolt 8 of the vertical adjustment block 2.

[0032] Among them, the horizontal correction platform 4 is a rectangular body as a whole, and the lateral adjustment block 3 is arranged on the top surface of the horizontal correction platform 4 to correct the X-axis accuracy of the suction block 13. At the same time, there is sufficient space on the top surface of the horizontal correction platform 4 to place the suction block 13.

[0033] Specifically, the lateral adjustment block 3 is a horizontally placed L-shaped structure, one L-shaped surface is attached to the top surface of the horizontal correction platform 4 and is screwed and fixed, and the other L-shaped surface corrects the X-axis direction of the air suction block 13. The L-shaped corner line of the lateral adjustment block 3, that is, the intersection line at the corner of the L-shaped block, is perpendicular to the hinge center axis.

[0034] This embodiment also includes a locking bolt 10, and the lateral adjustment block 3 is connected and fixed to the horizontal correction platform 4 through the locking bolt 10, and the auxiliary positioning block 6 is also connected and fixed to the vertical adjustment block 2 through the locking bolt 10. Specifically, the auxiliary positioning block 6 and the lateral adjustment block 3 are usually connected by at least two locking bolts 10, and the lateral adjustment block 3 is correspondingly provided with a first strip hole 11 for cooperating with the locking bolt 10, and the auxiliary positioning block 6 should be provided with a second strip hole 12 for cooperating with the locking bolt 10. The first strip hole 11 and the second strip hole 12 are parallel to the hinge center axis, and are used to adjust the position of the lateral adjustment block 3 and the auxiliary positioning block 6 in the X-axis direction, such as Figure 3 shown.

[0035] When in use, the filter rod compound machine needs to be stopped in advance, and the position of the insertion wheel 14 is disassembled, and the suction blocks 13 are evenly arranged on the insertion wheel 14 around the circumference. Figure 4 Assemble the calibration fixture so that the height of the vertical support rod 5 matches the support height of the vertical adjustment block 2, ensuring that the horizontal calibration platform 4 can remain horizontal during calibration. At the same time, ensure that the auxiliary positioning block 6 and the horizontal adjustment block 3 are positioned accurately.

[0036] First, rotate the insertion wheel 14 to randomly place a suction block 13 in an approximately horizontal position, and rotate the horizontal correction platform 4 to place the suction block 13 in a horizontal position on the horizontal correction platform 4. The horizontal correction platform 4 remains horizontal due to the support of the vertical adjustment block 2. Then, visually observe whether the bottom surface of the suction block 13, i.e., the Y-axis direction, is in close contact with the horizontal correction platform 4, and whether the side surface of the suction block 13, i.e., the X-axis direction, is in close contact with the horizontal adjustment block 3. If there is a contact gap, it means that the position of the suction block 13 is deviated and needs to be corrected.

[0037] By rotating the insertion wheel 14 to switch different air suction blocks 13, the air suction blocks 13 are quickly checked and corrected one by one. The entire inspection and correction process is convenient, fast, more targeted, and effectively improves maintenance efficiency.
