Abstract
Description
Technical Field
[0001] This application relates to the field of conveyor equipment technology, specifically to a belt installation and adjustment device and a packaging production line. Background Technology
[0002] The cigarette pack output flipping device widely used in cigarette packaging equipment is a set of belt drive devices driven by a motor. The cigarette packs are conveyed forward to their positions through the synchronous toothed belt. Because the belt is biased to one side of the cigarette packs, the cigarette packs will flip to the bottom side due to gravity after being conveyed to their positions, and then be transferred to the next process through the conveying channel.
[0003] To provide sufficient support for the cigarette sticks during the conveying process, the cigarette stick conveyor belts all use synchronous toothed belts with a wide contact area as the power transmission medium. This is because a wider synchronous toothed belt can ensure that the cigarette sticks are conveyed smoothly over short distances even when the contact with the cigarette sticks is biased to one side. However, in actual use, this structure has problems. Due to the characteristics of the synchronous toothed belt drive structure, the synchronous toothed belt is embedded in the pulley, making installation and disassembly very inconvenient. Utility Model Content
[0004] The purpose of this application is to provide a belt installation and adjustment device and a packaging production line to solve the defects of the cumbersome process of installing and disassembling the conveyor belt (belt) in the prior art.
[0005] To achieve the above objectives, this application employs the following technical solution:

[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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. Example 1
[0032] like Figure 1 and Figure 2As shown, this embodiment discloses a belt mounting and adjusting device, which includes a mounting bracket 9, a second connecting part 200, and a driving part 300. The mounting bracket 9 is rotatably mounted with a first connecting part 100 and a swing arm 6, which can swing in an arc around the rotating part. The second connecting part 200 is rotatably mounted on the swing arm 6, and a belt 1 is tensioned between the second connecting part 200 and the first connecting part 100. When the second connecting part 200, the second connecting part 200, and the swing arm 6 are collinear, the swing arm 6 is fixedly connected to the mounting bracket 9. The driving part 300 is connected to the first connecting part 100 for transmission. The driving part here also uses a driving wheel in conjunction with a belt for transmission. Some embodiments use a gear meshing transmission method, which are all prior art and will not be described in detail here.
[0033] When using, as shown in the attached document Figure 3 By swinging the swing arm 6 around the rotation point, the distance between the second connecting part 200 and the first connecting part 100 changes, as shown in the attached figure. Figure 1 The swing arm 6 rotates clockwise. As the swing arm 6 rotates upward around the movable seat 8, the distance between the second connecting part 200 and the first connecting part 100 gradually decreases. This facilitates the installation and removal of the belt 1 between the second connecting part 200 and the first connecting part 100. When the center point of the second connecting part 200, the first connecting part 100 and the swing arm 6 are collinear, the swing arm 6 and the mounting bracket 9 are fixed by the second fastener 62. Only after the swing arm 6 is fixed can the belt 1 be guaranteed to run normally and stably. The cigarette stick enters the belt 1 in this embodiment from the conveyor belt at the wide end. The width between the two belts 1 in this device is less than the width of the cigarette stick. At this time, the cigarette stick falls to the side away from the mounting bracket 9 and then enters the next process. One end of the mounting bracket 9 is fixed with a baffle.
[0034] In a further embodiment, as shown in the appendix Figure 2 and Figure 5 As shown, in order to assist in fixing the position of the swing arm 6, a positioning block 7 is set on the mounting bracket 9 below the swing arm 6. This positioning block 7 is versatile. In the design, an oblong hole is opened on the positioning block 7, and a locking element (bolt) is provided in the oblong hole. According to the final horizontal position of the swing arm 6, the position of the positioning block 7 is adjusted adaptively through the oblong hole and fixed by the locking element. When the positioning block 7 is in use, the oblong hole is set vertically, and the positioning block 7 adaptively limits the downward position of the swing arm 6.
[0035] Continue to observe the appendix Figure 2 and Figure 3 In this embodiment, the first connecting part 100 rotates and drives the second connecting part 200 to rotate via the belt 1. In this embodiment, the first connecting part 100 includes two driving wheels 2 and a first wheel shaft 41. The first wheel shaft 41 is rotatably mounted on the mounting bracket 9 via a bearing. The two driving wheels 2 are coaxially and parallelly fixedly connected to the first wheel shaft 41.
[0036] The second connection includes two driven wheels 3 and a second wheel shaft 42. The second wheel shaft 42 is rotatably mounted on the swing arm 6 via bearings. The two driven wheels 3 are coaxially and parallelly fixedly connected to the second wheel shaft 42. The two driving wheels 2 and the two driven wheels 3 are arranged in a one-to-one correspondence. At this time, the two belts 1 are parallel to each other. Here, the belts 1 are polyurethane round belts 1 used for cigarette bar transportation. They do not contain steel wires and will not affect the appearance of the cigarette bar products. They have advantages such as strong wear resistance, light weight, good toughness, and environmental protection. They are widely suitable for high-precision industries such as food machinery and medical machinery. The selection and application are very convenient.
[0037] The driving wheel 2 is mounted on the first shaft 41 by a key and fasteners, and the driven wheel 3 is also mounted by a key and fasteners. Changing the mounting position of the driving wheel 2 on the shaft 41 can adjust the distance between the two driving wheels 2, and changing the mounting position of the driven wheel 3 on the shaft 42 can adjust the distance between the two driven wheels 3. The driving wheel 2 and the driven wheel 3 can be axially adjusted on the shaft. By changing the contact position between the belt 1 and the bottom of the cigarette stick, the cigarette stick is transported more smoothly and it is easier to flip the cigarette stick.
[0038] The designers, considering the device's versatility, developed a more practical design solution, as shown in the attached document. Figure 1 , Figure 4 and Figure 5 Height adjustment was added to the driving wheel 2 and the driven wheel 3; the specific design scheme is as follows;
[0039] The first connecting part 100 includes an eccentric bearing seat 5. A boss 51 is provided on one side of the eccentric bearing seat 5. The boss 51 has a bearing mounting hole. The bearing inside the boss 51 is fixed non-coaxially with the eccentric bearing seat 5. The mounting surfaces of the boss 51 and the eccentric bearing seat 5 are perpendicular. Here, the axis of the bearing mounting hole inside the boss 51 is set 2mm away from the axis of the eccentric bearing seat 5. This data is designed to be adaptable to the height range of the transported items in the design and production. The mounting surface of the eccentric bearing seat 5, which is coaxial with the boss 51, has two radially symmetrical arc-shaped through grooves 52. The third fastener 53 passes through the arc-shaped through grooves 52 and firmly fixes the eccentric bearing seat 5 to the mounting bracket 9. The eccentric bearing seat 5 on the driven wheel 3 is designed and installed in the same way, except that the installation position is on the swing arm 6. The diameter of the through hole on the mounting bracket 9 is large enough to allow the boss 51 to rotate around the axis.
[0040] When the height of the drive wheel 2 needs to be adjusted, the third fastener 53 is loosened, causing the eccentric bearing seat 5 to rotate along the arc center of the arc groove 52 (which is also the center point of the boss 51). Since the boss 51 and the bearing mounting hole inside the boss 51 are not concentric, the eccentric bearing seat 5 rotates, and the bearing and shaft 41 inside the boss 51 change in height, which ultimately causes the height of the drive wheel 2 to change to meet the docking requirements of different heights at the input end.
[0041] It should be noted that when the height of the driven wheel 3 needs to be adjusted, in addition to adjusting the height of the driving wheel 2 as described above, the position of the swing arm 6 can also be adjusted by adjusting the up and down position of the positioning block 7, so that the height of the driven wheel 3 meets the usage requirements, provided that the oblong hole on the swing arm 6 does not affect the use of the second fastener 62.
[0042] Normally, the mounting bracket 9 is provided with a receiving groove, and the second connecting part 200 is placed in the receiving groove. The second connecting part 200, the first connecting part 100 and the swing arm 6 are distributed on both sides of the mounting bracket 9; this facilitates the installation and use of the components.
[0043] As attached Figure 2 As shown, the rotation point of the swing arm 6 in this embodiment is adjustable; the swing arm 6 is provided with a mounting hole, and a movable seat 8 is provided in the mounting hole. The mounting bracket 9 is provided with an adjustment groove 10. The movable seat 8 is fixed to the adjustment groove 10 by the first fastener 61, and the swing arm 6 rotates around the movable seat 8; at the same time, a waist hole is opened in the middle of the swing arm 6; the waist hole corresponds to the adjustment groove 10, allowing the swing arm 6 to move in the length direction. After moving into place, the swing arm 6 is fixed to the mounting bracket 9 by the second fastener 62, ensuring that the swing arm 6 and the second connecting part 200 do not move in the working state, and at the same time ensuring that the axes of the first connecting part 100 and the second connecting part 200 are parallel.
[0044] In use, loosen the first fastener 61 and the second fastener 62 so that the position coordinates of the movable seat 8 can move along the length direction of the adjustment groove 10. At this time, the locking position of the first fastener 61 and the movable seat 8 on the mounting bracket 9 changes. Move the swing arm 6 left and right to adjust the distance between the driving wheel 2 and the driven wheel 3. This adjustment can be used when the belt 1 is installed for the first time, and it also meets the usage conditions when the belt 1 needs to be replaced after a long period of use, without the need to adjust the distance again.
[0045] The fasteners in the above embodiments use bolts or combinations of bolts and nuts. Example 2
