Description
Technical Field
[0001] This application relates to the field of cigarette box production equipment technology, and in particular to a folding device auxiliary positioning device. Background Technology
[0002] The YB45 hard-pack packaging machine is a high-speed packaging equipment widely used in the cigarette industry, mainly used to complete the packaging and forming of hard-pack cigarettes.
[0003] The YB45 packaging machine's No. 5 wheel folds two planes of the cigarette box via a movable folding mechanism. This movable folding mechanism is a parallel four-bar linkage, consisting of an inner folding plate and an outer folding plate. The adjustment requirements are as follows: the distance between the inner wall of the inner folding plate and the inner wall of the rear semicircular plate is 0.5 mm, and the distance between them is 5 mm; the distance between the inner wall of the outer folding plate and the inner wall of the front semicircular plate is 0.5 mm, and the distance between them is 5 mm.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0032] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0033] It should be noted that the directional terms such as "upper end," "lower end," "left side," and "right side" mentioned below are defined based on the accompanying drawings in the instruction manual.
[0034] like Figures 1 to 8 As shown in the embodiment of this application, the folding device auxiliary positioning device includes a first positioning component and a second positioning component. The first positioning component includes a first positioning plate 1 and a second positioning plate 2. The first positioning plate 1 and the second positioning plate 2 are connected by a connecting component 5. The first positioning plate 1 has a first positioning surface 101 and a second positioning surface 102. The first positioning surface 101 can abut against the inner folding plate 100, and the second positioning surface 102 can abut against the rear semicircular plate 300. The first positioning surface 101 extends outward by 0.5 mm relative to the second positioning surface 102. The second positioning plate 2 has a third positioning surface and a second positioning surface. The fourth positioning surface has four positioning surfaces. The third positioning surface can abut against the outer folding plate 200, and the fourth positioning surface can abut against the front semicircular plate 400. The third positioning surface extends outward by 0.5 mm relative to the fourth positioning surface. The second positioning component includes a third positioning plate 3 and a fourth positioning plate 4. The thickness of the third positioning plate 3 and the fourth positioning plate 4 is 5 mm. The third positioning plate 3 is located on the first positioning plate 1, and the fourth positioning plate 4 is located on the second positioning plate 2. The third positioning plate 3 can be placed between the inner folding plate 100 and the rear semicircular plate 300, and the fourth positioning plate 4 can be placed between the outer folding plate 200 and the front semicircular plate 400.
[0035] Specifically, such as Figure 1 As shown, the first positioning plate 1 includes a first segment and a second segment. The thickness of the first segment is 0.5 mm thicker than that of the second segment, and the inner wall of the first segment is flush with the outer wall of the second segment. The first segment is a square plate, and the second segment is an arc-shaped plate, with the arc of the second segment being the same as that of the rear semicircular plate 300. The outer wall of the first segment is the first positioning surface 101, and the outer wall of the second segment is the second positioning surface 102. The first positioning surface 101 protrudes outward by 0.5 mm more than the second positioning surface 102. A mounting groove is provided at the connection between the first segment and the second segment. The third positioning plate 3 is fixedly installed in the mounting groove by bolts. The third positioning plate 3 extends outward and has a thickness of 5 mm. The second positioning plate 2 has the same structure as the first positioning plate 1. A fourth positioning plate 4 is fixed on the second positioning plate 2. The first positioning plate 1 and the second positioning plate 2 are distributed parallel to each other and are connected together by a connecting component 5. The first positioning plate 1 and the second positioning plate 2 are symmetrically distributed about the midpoint of the connecting component 5.
[0036] Understandably, when adjusting the movable folding mechanism, the auxiliary positioning device is placed inside the movable folding mechanism, and the first positioning surface 101 of the first positioning plate 1 is tightly attached to the inner folding plate 100, and the second positioning surface 102 is tightly attached to the rear semicircular plate 300. Since the first positioning surface 101 protrudes outward by 0.5 mm more than the second positioning surface 102, when the inner sidewalls of the inner folding plate 100 and the rear semicircular plate 300 are tightly attached to the first positioning surface 101 and the second positioning surface 102 respectively, the distance between the inner wall of the inner folding plate 100 and the inner wall of the rear semicircular plate 300 can be guaranteed. The thickness is 0.5 mm. The third positioning plate 3 is located between the inner folding plate 100 and the rear semicircular plate 300. Since the thickness of the third positioning plate 3 is 5 mm, when the inner folding plate 100 and the rear semicircular plate 300 are tightly attached to the two side walls of the third positioning plate 3 respectively, the distance between the inner folding plate 100 and the rear semicircular plate 300 can be guaranteed to be 5 mm. Similarly, the distance between the inner wall of the outer folding plate 200 and the inner wall of the front semicircular plate 400 can be guaranteed to be 0.5 mm and the distance between the outer folding plate 200 and the front semicircular plate 400 can be guaranteed to be 5 mm.
[0037] In some embodiments, the connecting component 5 includes a connecting shaft 51 and a connecting sleeve 52. The connecting shaft 51 is connected to the first positioning plate 1, the connecting sleeve 52 is connected to the second positioning plate 2, and the connecting shaft 51 is connected to the connecting sleeve 52.
[0038] Specifically, one end of the connecting shaft 51 is provided with a first mounting plate, which has two spaced mounting holes located on both sides of the connecting shaft 51 and symmetrically distributed about the connecting shaft 51. Bolts pass through the mounting holes and threadedly engage with the threaded holes on the first mounting plate, allowing the first mounting plate to be fixed to the inner wall of the first positioning plate 1. One end of the connecting sleeve 52 is provided with a second mounting plate, which has the same structure as the first mounting plate. The second mounting plate is fixed to the inner wall of the second positioning plate 2 by bolts. The connecting shaft 51 and the connecting sleeve 52 are connected to each other, forming a connecting frame. Two connecting frames are parallel and spaced between the first positioning plate 1 and the second positioning plate 2, forming a rectangular frame structure between the first positioning plate 1, the second positioning plate 2, and the two connecting frames.
[0039] It is understandable that the connecting component 5 can connect the first positioning plate 1 and the second positioning plate 2 together, while ensuring the parallel spacing between the first positioning plate 1 and the second positioning plate 2.
[0040] Based on the above embodiments, the connecting sleeve 52 is provided with a first elastic element, the connecting shaft 51 extends into the guide sleeve 62 and is elastically connected to the connecting sleeve 52 through the first elastic element, and the connecting shaft 51 and the connecting sleeve 52 are slidably engaged.
[0041] Specifically, the inner diameter of the connecting sleeve 52 is the same as the diameter of the connecting shaft 51, and the connecting shaft 51 can extend into the connecting sleeve 52. The first elastic element can be a compression spring, one end of which is fixedly connected to the end of the connecting shaft 51, and the other end of which is fixedly connected to the end of the connecting sleeve 52. The connecting shaft 51 and the connecting sleeve 52 are in sliding fit.
[0042] It is understood that the connecting shaft 51 can move relative to the connecting sleeve 52 along the axial direction of the connecting sleeve 52 within the connecting sleeve 52, thereby adjusting the distance between the first positioning plate 1 and the second positioning plate 2 to suit different sizes of movable folding devices.
[0043] In some embodiments, such as Figure 1 , Figure 4 and Figure 5 As shown, the folding device auxiliary positioning device is also provided with a guide assembly 6. The guide assembly 6 includes a guide shaft 61, a guide sleeve 62, a second elastic element, and a first limiting shaft 63. The guide shaft 61 is connected to the first positioning plate 1, and the guide sleeve 62 is connected to the second positioning plate 2. The guide shaft 61 extends into the guide sleeve 62 and is elastically connected to the guide sleeve 62 through the second elastic element. The guide shaft 61 and the guide sleeve 62 are slidably engaged. The guide sleeve 62 is provided with a first limiting groove 621, which extends along the axial direction of the guide sleeve 62. The first limiting shaft 63 is provided on the guide shaft 61 and is slidably engaged in the first limiting groove 621. The first limiting shaft 63 can move within the first limiting groove 621.
[0044] Specifically, the guide assembly 6 has a similar shape to the connecting assembly 5, the second elastic element can be a compression spring, the first limiting shaft 63 is perpendicular to the guide shaft 61, and an L-shaped structure is formed between the first limiting shaft 63 and the guide shaft 61. The first limiting shaft 63 extends out of the guide sleeve 62 through the first limiting groove 621.
[0045] It is understandable that the guide shaft 61 can move along the axial direction of the guide sleeve 62. During the movement of the guide shaft 61, the first limiting shaft 63 will slide in the first limiting groove 621. When the first limiting shaft 63 moves to the end of the first limiting groove 621, the first limiting groove 621 can restrict the first limiting shaft 63 from continuing to move, thereby preventing the guide shaft 61 from continuing to move. Since the guide shaft 61 is fixedly connected to the first positioning plate 1, the movement of the first positioning plate 1 is restricted. By setting the first limiting groove 621, the range of movement of the first positioning plate 1 towards or away from the second positioning plate 2 can be restricted, thus preventing the connecting shaft 51 from detaching from the connecting sleeve 52.
[0046] In some embodiments, such as Figure 1 , Figure 6As shown, the folding auxiliary positioning device is also provided with a drive rod 8, a first bracket 7 is provided on the second positioning plate 2, the drive rod 8 is slidably engaged with the first bracket 7, the bottom of the drive rod 8 is provided with a drive groove 81, the drive groove 81 is inclinedly distributed, the first limiting shaft 63 is slidably engaged with the drive groove 81, and the drive rod 8 can move up and down.
[0047] It is understandable that by moving the drive rod 8 up and down, the drive groove 81 can be moved up and down. Since the first limiting shaft 63 is located in the drive groove 81 and the first limiting groove 621 restricts the up and down movement of the first limiting shaft 63, when the drive groove 81 moves up and down, the drive groove 81 can push the first limiting shaft 63 to move along the first limiting groove 621 within the first limiting groove 621. The first limiting shaft 63 drives the guide shaft 61 to overcome the elastic force of the compression spring and move along the axial direction of the guide sleeve 62, thereby driving the first positioning plate 1 to move. When the drive rod 8 moves upward, the guide shaft 61 overcomes the elastic force of the second elastic element and causes the second elastic element to contract, and the first positioning plate 1 moves closer to the second positioning plate 2. When the drive rod 8 moves downward, the compression spring releases its elastic force and moves the first positioning plate 1 away from the second positioning plate 2.
[0048] In some embodiments, such as Figure 1 , Figure 6 and Figure 7 As shown, the first bracket 7 is provided with a limiting sleeve 9, which is sleeved on the drive rod 8. The drive rod 8 is provided with a second limiting groove 82, which extends along the axial direction of the drive rod 8. The limiting sleeve 9 is provided with a second limiting shaft 10, which is slidably fitted in the second limiting groove 82.
[0049] Understandably, the limiting sleeve 9 is fixedly installed below the first bracket 7 by bolts, and the drive rod 8 is sleeved inside the limiting sleeve 9. The limiting sleeve 9 can restrict the movement of the drive rod 8 in the horizontal plane. The second limiting shaft 10 is fixedly installed on the inner wall of the limiting sleeve 9 and extends radially inward along the limiting sleeve 9. The second limiting groove 82 is provided on the side wall of the drive rod 8 and extends in the vertical direction. The second limiting shaft 10 extends into the second limiting groove 82. The second limiting shaft 10 and the limiting sleeve 9 can restrict the five degrees of freedom of the drive rod 8, so that the drive rod 8 can only move in the vertical direction. When the drive rod 8 moves up or down to its limit, the end of the second limiting shaft 10 abuts against the end of the second limiting groove 82. The second limiting groove 82 can restrict the range of vertical movement of the drive rod 8.
[0050] In some embodiments, the upper end of the drive rod 8 is provided with a hook 11, which is located above the first bracket 7.
[0051] It is understandable that the hook 11 is provided so that workers can pull the drive rod 8 through the hook 11 to manually control the up and down movement of the drive rod 8.
[0052] In some embodiments, the top of the drive rod 8 is provided with a limiting boss 83, and the bottom of the hook 11 is provided with a mating groove. The limiting boss 83 extends into the mating groove and engages with the mating groove.
[0053] Understandably, by setting the limiting boss 83, the hook 11 is prevented from rotating relative to the drive rod 8, thus improving safety.
[0054] In some embodiments, the second positioning plate 2 is further provided with a second bracket 12, and the second bracket 12 is provided with a handle 13.
[0055] Understandably, by setting handle 13, it is easier for staff to lift the folding auxiliary positioning device and facilitate the transfer of the folding auxiliary positioning device.
[0056] In some embodiments, the handle 13 is located directly above the hook 11.
[0057] It is understandable that when pulling the hook 11, the handle 13 can be used as a support, making it easier for the worker to pull the hook 11 with one hand.
[0058] The working principle of the folding auxiliary positioning device in this application is as follows:
[0059] like Figure 8 As shown, the auxiliary positioning device for the folding mechanism is placed inside the movable folding mechanism, and the first positioning surface 101 of the first positioning plate 1 is in close contact with the inner folding plate 100, and the second positioning surface 102 is in close contact with the rear semicircular plate 300. Since the first positioning surface 101 protrudes outward by 0.5 mm more than the second positioning surface 102, when the inner sidewalls of the inner folding plate 100 and the rear semicircular plate 300 are in close contact with the first positioning surface 101 and the second positioning surface 102 respectively, the distance between the inner wall of the inner folding plate 100 and the inner wall of the rear semicircular plate 300 can be guaranteed to be 0.5 mm. The third positioning plate 3 is located between the inner folding plate 100 and the rear semicircular plate 300. Since the thickness of the third positioning plate 3 is 5 mm, when the inner folding plate 100 and the rear semicircular plate 300 are tightly attached to the two side walls of the third positioning plate 3 respectively, the distance between the inner folding plate 100 and the rear semicircular plate 300 can be guaranteed to be 5 mm. Similarly, the second positioning plate 2 and the fourth positioning plate 4 can be used to ensure that the distance between the inner wall of the outer folding plate 200 and the inner wall of the front semicircular plate 400 is 0.5 mm, and the distance between the outer folding plate 200 and the front semicircular plate 400 is 5 mm.
[0060] When the inner folding plate 100 and the outer folding plate 200 need to be adjusted, remove the inner folding plate 100 and the outer folding plate 200, and lift the hook 11 to drive the drive rod 8 to move upward. The drive rod 8 drives the first limiting shaft 63 to move through the second limiting groove 82. The first limiting shaft 63 drives the guide shaft 61 to move against the elastic force of the second elastic element and compress the second elastic element. The first positioning plate 1 gradually approaches the second positioning plate 2. When the first positioning plate 1 approaches the second positioning plate 2 to the specified position, place the folding auxiliary positioning device between the front semicircular plate 400 and the rear semicircular plate 300, release the hook 11, and the first elastic element and the second elastic element release their elastic force, so that the third positioning surface is in close contact with the rear semicircular plate 300 and the fourth positioning surface is in close contact with the front semicircular plate 400. Then install the inner folding plate 100 and the outer folding plate 200, and make the inner folding plate 100 in close contact with the first positioning surface 101 and the outer folding plate 200 in close contact with the second positioning surface 102 to realize the adjustment of the movable folding device.
[0061] In summary, the folding device of this application enables convenient and rapid adjustment of the movable folding mechanism.
