Description

Technical Field

[0001] The present application relates to the technical field of tobacco packaging, and in particular to a tool for adjusting the position of an electric soldering iron on a small transparent paper forming wheel of a hard box packaging machine. Background Art

[0002] The small box transparent paper forming wheel of a rigid box packaging machine (such as the GDX2 medium-speed rigid box packaging machine) is responsible for covering small cigarette packs with transparent paper. It folds each side of the transparent paper and heat-seals specific sides during the rotation and conveyance of the small cigarette packs. The main component of this part of the machine is the rotating head, called the small box transparent paper forming wheel, which rotates intermittently and is in the heat sealing position when it stops. Figure 1 、 Figure 2 As shown, the forming wheel 1 has six inlays 2, with cigarette packs (the transparent paper covering the packs is in different stages of folding) at four stations (A, B, C, and D). The cigarette packs, along with the transparent paper sheets, pass through the wrapping and forming material storage and enter the small box transparent paper forming wheel. In the subsequent heat sealing phase, the side edges are heat-sealed before output. The machine is equipped with two side heat-sealing electric soldering irons 3, located in stations B (the first heat sealing station) and C (the second heat sealing station), respectively, which apply alternating pressure to the sides of the cigarette packs. For detailed structure, please refer to the Chinese patent publication number CN204433164U, entitled "A Heat Sealing Device for Hard Box Outer Wrap Film Sealing Machine."

[0003] If the soldering iron is not adjusted properly at the right height (e.g., too high), a large gap will exist between the heated surface of the soldering iron and the surface of the cigarette pack's transparent paper, preventing effective heat sealing and ironing of the transparent paper. This can lead to defects such as the incompletely heat-sealed transparent paper spreading or noticeable wrinkles on the transparent paper surface. If the soldering iron is too low, excessive downward pressure will be applied when the soldering iron is pressed down to heat-seal and iron the transparent paper, causing indentations on the cigarette pack surface and potentially even scratching and interfering with the rotating forming wheel and the cigarette pack. Therefore, correctly adjusting the soldering iron's height relative to the packaging machine's transparent paper forming wheel is crucial to ensuring the quality of the packaging surface.

[0004] The most common method for correctly adjusting the height of the soldering iron on the forming wheel for small transparent paper boxes in packaging machines is to insert a metal gauge block the size of a cigarette pack into the forming wheel insert, manually turn the iron to the downward pressing working position, adjust the height of the soldering iron according to the position of the gauge block, and then adjust the height of the soldering iron as appropriate based on manual turning and observing the actual compression of the soldering iron on the cigarette pack. The left and right position of the soldering iron is also fine-tuned based on the position of the soldering iron relative to the side of the forming wheel insert and the opening of the curved cover when the soldering iron is pressed down. The main steps are as follows:

[0005] 1. Remove the entire forming wheel and insert a cigarette-pack-sized metal gauge block into the forming wheel insert. Install the forming wheel. Manually rotate the wheel until the insert and gauge block are under the soldering iron. Press the soldering iron down to the working position. Loosen the soldering iron arm clamping screw and rotate the soldering iron arm until the soldering iron presses against the cigarette-pack-sized metal gauge block in the forming wheel insert. Tighten the soldering iron arm clamping screw.

[0006] 2. Use a cigarette pack to push the forming wheel, turn the car to the working position below the soldering iron, press the soldering iron down, and observe whether the cigarette pack indentation, the front and rear sides of the soldering iron relative to the forming wheel insert, and the position of the arc plate opening interfere with each other, and make fine adjustments to the height and left and right position of the soldering iron.

[0007] The above adjustment steps are tedious and complex, requiring the gauge block and soldering iron to be adjusted separately, which is time-consuming. Furthermore, since the second step, fine-tuning based on the cigarette pack indentation and the relative position of the soldering iron, relies on observation, experience, and feel, it is highly subjective and can easily lead to inaccurate adjustments, affecting the appearance quality of the cigarette pack.

[0008] The most important thing is that after using the gauge block for adjustment and testing the machine, if you find that the pressure of the soldering iron on the actual cigarette pack is too high or too low (damaging it or the hot sticking effect is not good), you can only adjust the height of the soldering iron appropriately based on experience and feel (or remove the gauge block, thicken the sticker or replace it with a smaller gauge block and then reinsert it into the forming wheel insert and readjust it), which is extremely inconvenient to adjust. Utility Model Content

[0009] In order to solve the above technical problems, the purpose of the utility model is to provide a tool for adjusting the position of the electric soldering iron of the small box transparent paper forming wheel of a hard box packaging machine, which is convenient and accurate to adjust.

[0010] The technical solutions provided by this utility model are as follows:

[0011] A tool for adjusting the position of an electric soldering iron on a small transparent paper forming wheel of a rigid box packaging machine is provided for adjusting the position of the electric soldering iron corresponding to the small transparent paper forming wheel. The tool comprises a main body, two first inlays, and a first positioning block. The main body comprises a wheel body having an axial hole, and a first inner wing and a first outer wing extending in the same direction from the circumference of the wheel body. The first inner wing and the first outer wing constitute a first wing group and are both provided with a groove radially arranged along the wheel body and open at the end. The two first inlays are respectively fixed in the two grooves to form a receiving groove between the two first wings. The dimensions and positions of the axial hole and the receiving groove are the same as those of the axial hole and the cigarette clamping groove in the forming wheel, so that the structure composed of the main body and the first inlays simulates the forming wheel. The first positioning block is fixed to the outer end of the receiving groove so that its outer surface simulates the surface of a cigarette pack facing the electric soldering iron. The position of the first positioning block in the receiving groove is adjustable. After the first positioning block is adjusted into position, the tool is installed on the rigid box packaging machine, the main body is rotated to the heat sealing station, and the electric soldering iron is then placed against the outer surface of the first positioning block to adjust the height of the electric soldering iron.

[0012] Preferably, the main body also includes a second side wing group, the second side wing group includes a second inner wing and a second outer wing, the second side wing group has the same structure as the first side wing group, is arranged along the periphery of the wheel body, and the positions correspond to the first heat sealing station and the second heat sealing station respectively; the tooling also includes two second inlays and second positioning blocks for cooperating with the second side wing group, the second inlay and the second positioning block have the same structure as the first inlay and the first positioning block respectively.

[0013] Preferably, the side wings of the main body only include a first side wing group and a second side wing group.

[0014] Preferably, the first inner wing and the second inner wing are connected via an inner connecting piece, and the first outer wing and the second outer wing are connected via an outer connecting piece.

[0015] Preferably, each of the first inlays is provided with a through hole arranged along the axial direction of the wheel body, and the tooling further comprises a fastening screw, which passes through the through hole and abuts against the end surface of the first positioning block to fix the first positioning block.

[0016] Preferably, each of the first inlays is provided with two through holes arranged in the transverse direction.

[0017] Preferably, the through hole is a long waist hole arranged along the longitudinal direction.

[0018] Compared with the prior art, the utility model discloses a tool for adjusting the position of the soldering iron on the forming wheel of transparent paper for small boxes of a hard box packaging machine. By setting a main body, two first inlays and a first positioning block, the position of the first positioning block in the accommodating groove is adjustable. After the first positioning block is adjusted into place, the tool is installed on the hard box packaging machine, the main body is rotated to the heat sealing position, and then the soldering iron is placed against the outer surface of the first positioning block to adjust the height position of the soldering iron. This means that when it is found that the height of the soldering iron is too high or too low and needs fine-tuning during the adjustment process, it is no longer necessary to rely on experience and feel. Instead, the position of the soldering iron can be accurately fine-tuned by adjusting the height of the positioning block without frequently disassembling and assembling the forming wheel.

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

[0029] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the conditions under which this application can be implemented. Therefore, they have no substantive technical significance. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical content disclosed in this application without affecting the efficacy and purpose that can be achieved by this application.

[0030] like Figures 3 to 5 As shown, an embodiment of the present invention provides a soldering iron position adjustment tool for the small box transparent paper forming wheel of a hard box packaging machine, which is used to adjust the position of the soldering iron corresponding to the small box transparent paper forming wheel.

[0031] The tool comprises a main body 4 , two first inlays 5 , a first positioning block 6 , two second inlays 7 , and a second positioning block (not shown).

[0032] The main body 4 comprises a wheel 41 with an axial hole 411, and a first inner wing 42 and a first outer wing 43 extending in the same direction from the circumference of the wheel 41. The first inner wing 42 and the first outer wing 43 form a first wing group, and each wing is provided with a groove 44 extending radially along the wheel 41 and open at its distal end. Also extending in the same direction from the circumference of the wheel 41 are a second inner wing 45 and a second outer wing 46, forming a second wing group. The second wing group has the same structure as the first wing group and is arranged along the circumference of the wheel 41, corresponding to the first and second heat sealing stations, respectively.

[0033] The two first inlays 5 are respectively fixed in the grooves 44 of the first inner wing 42 and the first outer wing 43 to form a receiving groove between the two first wings. The size and position of the shaft hole 411 and the receiving groove are the same as the size and position of the shaft hole and the cigarette clamping groove in the forming wheel, so that the structure composed of the main body 4 and the first inlays 5 simulates the forming wheel. The first positioning block 6 is fixed to the outer end of the receiving groove so that its outer surface simulates the surface of the cigarette pack facing the soldering iron. The position of the first positioning block 6 in the receiving groove is adjustable. After the first positioning block 6 is adjusted into place, the tooling is installed on the hard box packaging machine, the main body 4 is rotated to the first heat sealing station, and then the soldering iron is placed against the outer surface of the first positioning block 6 to adjust the height position of the soldering iron.

[0034] The second inlay 7 and the second positioning block have the same structure as the first inlay 5 and the first positioning block 6 respectively, and cooperate with the groove 44 of the second inner wing 45 and the second outer wing 46 respectively to adjust the height position of the electric soldering iron in the second heat sealing station.

[0035] In this embodiment, the main body 4 comprises only a first wing group and a second wing group, resulting in a simpler structure compared to a forming wheel with six wing groups. Providing two wing groups effectively ensures that the front and rear soldering irons can be adjusted simultaneously and to the same height. Of course, in other embodiments, only one wing group can be provided, resulting in a simpler structure. If only one wing group is provided, only two inlays and one positioning block are required.

[0036] In this embodiment, the first inner wing 42 and the second inner wing 45 are connected by an inner connecting piece 47 , and the first outer wing 43 and the second outer wing 46 are connected by an outer connecting piece 48 , so that the structure is more solid.

[0037] In this embodiment, each first inlay 5 has a through-hole 51 axially arranged along the wheel body 41. The tooling also includes a fastening screw (not shown) that passes through the through-hole 51 and abuts against the end surface of the first positioning block 6 to secure the first positioning block 6. Preferably, each first inlay 5 has two transverse through-holes 51 to prevent the first positioning block 6 from rotating. Preferably, the through-holes 51 are longitudinally elongated to facilitate insertion and position adjustment of the fastening screw.

[0038] During use, remove the transparent paper forming wheel from the equipment box and install the newly designed adjustment tool in the original forming wheel position. The width between the front and rear sides of the tool positioning block is exactly the width of the soldering iron. This ensures that the soldering iron is stuck between the tool positioning blocks during adjustment, eliminating the need to adjust the front and rear positions. This avoids the need to adjust the front and rear entry and exit positions after height adjustment to ensure that there is no interference with the front and rear sides of the forming wheel positioning block. There are two long waist holes on the front and rear sides of the tool positioning block for screw adjustment. Before installation, adjust the positioning block to the standard position according to the cigarette pack. After installation, press the soldering iron directly onto the positioning block. If the indentation is too deep or the transparent paper is not hot enough during the cigarette pack turning, fine-tune the positioning block's fastening screws in the long waist holes. Then, place the soldering iron against the positioning block again to accurately adjust the soldering iron's height position. This effectively ensures that the front and rear soldering irons are adjusted simultaneously and to the same height.

[0039] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
