Description

Technical Field

[0001] The invention relates to the technical field of tobacco equipment, and in particular to a cigarette pack conveying synchronous belt adjusting device. Background Art

[0002] The cigarette packing machine is mainly used to wrap cigarettes in folded liner paper, attach white cardboard, and then complete the cigarette packaging work of wrapping trademark paper and transparent paper. Its purpose is to make it easy to carry cigarettes while keeping them moist and fragrant, extend the shelf life of cigarettes, and further highlight the product grade and brand culture.

[0003] In the prior art, the cigarette pack conveying process is as follows Figure 1 As shown, the belts 2 and 3 continuously receive vertical cigarette packs 4 from the lug belts 6. When the cigarette packs 4 enter the appearance inspection box 1, the camera in the appearance inspection box 1 will perform appearance inspection on the cigarette packs 4. Unqualified cigarette packs 4 will be removed at the cylinder 5, and qualified cigarette packs 4 will continue to be transported until they are received by the upper and lower synchronous belts 8. This is the entire process flow of the cigarette packs in this part. Through the process flow, it can be understood that the belts 2 and 3 are needed because the appearance inspection photography needs to detect the product surface as much as possible, so the belts 2 and 3 are designed to be narrow strips with a width of only 6mm, with two belts on the inside and outside, one long and one short, clamping the cigarette packs 4 forward. In order to ensure that the belts are always kept tight, the belts 7 are continuously tensioned by spring force.

[0004] In actual production, the change in the specifications of the double-medium cigarette packs leads to unstable transportation of the cigarette packs 4 at the appearance inspection box 1, and the conveying level may deviate by 1-2 mm. Figure 1 As shown in the middle dotted line, when a certain amount of cigarette pack 4 has fallen and is transported to the intersection of the upper and lower synchronous belts 8 and the belts 2 and 3, the cigarette pack 4 does not directly enter the center position of the upper and lower synchronous belts 8 due to the fall, but the lower left corner of the cigarette pack 4 rubs against the lower synchronous belt. Since the lower synchronous belt is always rotating counterclockwise, the cigarette pack 4 moving forward obtains an upward force due to the wrap angle of the lower synchronous belt and the accompanying rotation. Since the upper and lower synchronous belts 8 rotate very fast, the cigarette pack 4 is ejected upward for a distance, which causes the upper left corner of the cigarette pack 4 to touch the upper synchronous belt, and the force balance of the cigarette pack 4 is broken, which directly causes the cigarette pack 4 to lean back and overturn.

[0005] The transmission design structure of the existing upper and lower synchronous belts 8 is a fixed flange bearing structure. Figure 2As shown, the upper synchronous belt is installed on the synchronous pulley 9, and the upper synchronous belt is driven by the rotation of the synchronous pulley 9. The synchronous pulley 9 is fixedly installed on the wheel shaft 10, and the wheel shaft 10 provides rotation drive. The wheel shaft 10 is supported and positioned in the flange sleeve 12 by the bearing 11. The bearing 11 is fixed to the flange sleeve 12, and the flange sleeve 12 is fixed to the wall panel 14 by the flange on the periphery through three screws 13. Although the wall panel 14 is adjustable, the wall panel 14 is the total installation plate of the entire output part of the cigarette packing machine. The change of the position of the wall panel 14 will affect the position of all parts installed on the wall panel 14, so the wall panel 14 is not suitable for adjustment here, so that the transmission design structure of the upper synchronous belt is a non-adjustable fixed structure. The transmission design structure of the lower synchronous belt is also similar and cannot be adjusted. Therefore, it is impossible to adjust the upper and lower synchronous belts 8 to avoid the cigarette packs 4 from hitting the upper and lower synchronous belts 8. The spacing between the belts 2 and 3 is determined by the relative position between the bracket and the bottom plate. Since there is a positioning pin between the bracket and the bottom plate, this position cannot be adjusted from a design perspective. This results in the cigarette pack 4 falling down being unable to be avoided by adjustment, the upper and lower synchronous belts 8 and the spacing between the belts 2 and 3 cannot be adjusted, and the elongation and wear of the belts 2 and 3 are inevitable. As a result, the overturning of the cigarette packs of the ZB418 model cannot be effectively solved. Summary of the invention

[0051] Furthermore, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0052] like Figure 3 and Figure 4 FIG. 1 is an embodiment of a cigarette pack conveying synchronous belt adjusting device of the present invention. The cigarette pack conveying synchronous belt adjusting device of this embodiment includes a flange sleeve and a wheel shaft 300 .

[0053] The flange sleeve includes an outer ring 100 and an inner sleeve 200. The outer ring 100 is axially penetrated, and the inner sleeve 200 is axially penetrated. The outer ring 100 is used to be connected and fixed to a fixed wall panel, so that the flange sleeve is connected and fixed to the wall panel. The inner sleeve 200 is rotatably inserted into the inner circumference 101 of the outer ring. By rotating the inner sleeve 200, the relative position of the inner sleeve 200 and the outer ring 100 in the circumferential direction can be adjusted. After the adjustment is in place, the inner sleeve 200 is positioned in the inner circumference 101 of the outer ring and remains relatively fixed with the outer ring 100. The outer circumference 202 of the inner sleeve is matched with the inner circumference 101 of the outer ring and can be relatively rotatably matched. The center of the outer circumference 202 of the inner sleeve coincides with the center of the inner circumference 101 of the outer ring. The inner circumference 201 of the inner sleeve is eccentrically arranged with the outer circumference 202 of the inner sleeve. Therefore, when the outer ring 100 is stationary and the inner sleeve 200 is rotated, the center of the outer circumference 202 of the inner sleeve remains coincident with the center of the inner circumference 101 of the outer ring, and the center of the inner circumference 201 of the inner sleeve has an upper and lower offset relative to the center of the inner circumference 101 of the outer ring.

[0054] The axle 300 is rotatably arranged in the inner circumference 201 of the inner sleeve. The axle 300 is used to connect the synchronous pulley, which is used to connect the synchronous belt. The axle 300 is driven to rotate, thereby driving the synchronous pulley to rotate and driving the synchronous belt to run. Since the axle 300 is concentrically arranged with the inner circumference 201 of the inner sleeve and positioned in the inner circumference 201 of the inner sleeve, when the upper and lower positions of the center of the inner circumference 201 of the inner sleeve are adjusted by rotating the inner sleeve 200, the upper and lower positions of the axle 300 will change synchronously, and at the same time, the upper and lower positions of the synchronous pulley and the synchronous belt will change together, thereby realizing the upper and lower position adjustment of the synchronous belt.

[0055] Therefore, the cigarette pack conveying synchronous belt adjustment device of this embodiment designs the flange sleeve as a split eccentric sleeve structure that can be rotated and adjusted. When the outer ring 100 is connected to the wall panel and fixed, the inner sleeve 200 with eccentric settings on the inner and outer circumferences is rotated to achieve the up and down position adjustment of the wheel axle 300 inserted in the inner circumference 201 of the inner sleeve, thereby achieving the purpose of achieving the up and down position adjustment of the synchronous belt.

[0056] See also Figure 4 As shown in 4a, it is the state when the center of the inner circumference 201 of the inner sleeve is located at the highest position above the center of the inner circumference 101 of the outer ring. At this time, the distance that the center of the inner circumference 201 of the inner sleeve is higher than the center of the inner circumference 101 of the outer ring is the eccentricity L between the inner circumference 201 of the inner sleeve and the outer circumference 202 of the inner sleeve, and the upper and lower positions of the axle 300 and the synchronous pulley and synchronous belt installed on the axle 300 are located at the highest position that can be adjusted. In this state, the inner sleeve 200 is rotated 180° to switch to the state where the center of the inner circumference 201 of the inner sleeve is located at the lowest position below the center of the inner circumference 101 of the outer ring (as shown in FIG. 4a). Figure 4 4b), at this time, the distance between the center of the inner circumference 201 of the inner sleeve and the center of the inner circumference 101 of the outer ring is also the eccentricity L between the inner circumference 201 of the inner sleeve and the outer circumference 202 of the inner sleeve, and the up and down positions of the axle 300 and the synchronous pulley and synchronous belt mounted on the axle 300 are at the lowest position that can be adjusted. According to actual application needs, by controlling the rotation angle of the inner sleeve 200, the up and down position adjustment range of the synchronous belt can be controlled.

[0057] In this embodiment, preferably, the eccentricity L between the inner circumference 201 of the inner sleeve and the outer circumference 202 of the inner sleeve is 1.5 mm to 2.5 mm. Preferably, the eccentricity L between the inner circumference 201 of the inner sleeve and the outer circumference 202 of the inner sleeve is 2 mm.

[0058] See also Figure 1In this embodiment, preferably, a plurality of connection holes 103 are provided at intervals along the circumferential direction on the outer ring 100, and the connection holes 103 penetrate the outer circumference 102 of the outer ring and the inner circumference 101 of the outer ring along the radial direction of the outer ring 100. A plurality of adjustment holes 203 are provided at intervals along the circumferential direction on the inner sleeve 200, and the adjustment holes 203 penetrate the outer circumference 202 of the inner sleeve and the inner circumference 201 of the inner sleeve along the radial direction of the inner sleeve 200. At least one connection hole 103 and at least one adjustment hole 203 are detachably connected through a connecting member 400. When the up and down position of the synchronous belt needs to be adjusted, the connecting member 400 is removed, so that the inner sleeve 200 can be rotated, and the inner sleeve 200 is rotated to a corresponding angle according to the adjustment requirements. When the inner sleeve 200 is rotated to the right position, the axis of at least one connection hole 103 and at least one adjustment hole 203 should coincide, so that the inner sleeve 200 and the outer ring 100 can be reconnected and fixed by the connecting member 400 after being rotated to the right position. The number and spacing angle of the connection holes 103 and the adjustment holes 203 determine the gears at which the synchronous belt can be adjusted up and down, and can be designed according to actual needs. For example, two connection holes 103 can be provided on the outer ring 100, and the two connection holes 103 are 120° apart. Correspondingly, at least two adjustment holes 203 are provided on the inner sleeve 200. Compared with the flange sleeve 12 in the prior art, the thickness of the outer ring 100 of the flange sleeve of this embodiment is increased along the axial extension, so as to add a connection hole 103 that penetrates to the inner circumference 101 of the outer ring on the outer circumference 102 of the outer ring.

[0059] Preferably, the adjustment hole 203 on the inner sleeve 200 and the connection hole 103 on the outer ring 100 are both threaded holes with internal threads, and the connecting member 400 is a screw threadedly connected to the threaded hole. Connecting the inner sleeve 200 and the outer ring 100 by screws has the advantages of convenient assembly and disassembly and easy operation.

[0060] In this embodiment, preferably, a plurality of mounting holes 104 are provided at intervals along the circumferential direction on the outer ring 100. The mounting holes 104 penetrate the outer ring 100 along the axial direction of the outer ring 100. The mounting holes 104 are used to connect with the wallboard through screws to achieve the connection and fixation of the outer ring 100 with the wallboard. The mounting holes 104 and the connecting holes 103 are staggered along the circumferential direction of the outer ring 100 to avoid mutual interference. Preferably, three mounting holes 104 are provided, and the three mounting holes 104 are evenly spaced along the circumferential direction of the outer ring 100.

[0061] In this embodiment, in order to match the installation dimensions of the inner sleeve 200 and increase the stability of the wheel axle 300, preferably, the wheel axle 300 is supported in the inner circumference 201 of the inner sleeve by multiple pairs of bearings 500. Increasing the number of bearings 500 can improve the load-bearing capacity and enhance stability. Preferably, the wheel axle 300 is supported in the inner circumference 201 of the inner sleeve by two pairs of four bearings 500. Both pairs of bearings 500 are arranged at the two ends of the wheel axle 300, with a sleeve 600 in the middle, and retaining rings 700 are arranged between the two ends of the sleeve 600 and the adjacent bearings 500.

[0062] The cigarette pack conveying synchronous belt adjustment device of this embodiment is applied to Figure 1 and Figure 2 The upper synchronous belt in the prior art shown in the figure replaces the original transmission design structure of the upper synchronous belt, and the outer ring 100 of the flange sleeve of the cigarette pack conveying synchronous belt adjustment device of this embodiment is connected and fixed to the wall panel 14, and the axle 300 is connected to the synchronous belt pulley 9. The cigarette pack conveying synchronous belt adjustment device of this embodiment can realize the up and down position adjustment of the upper synchronous belt installed on the synchronous belt pulley 9, thereby effectively solving the problem of small pack overturning that has long plagued the production line and improving the stability of cigarette pack conveying.

[0063] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
