Description

Technical Field

[0001] The utility model relates to the technical field of silicon-carbon material processing, in particular to a synchronous toothed belt conveying device suitable for soft-pack hardening cigarette packs of a YB25 packaging machine. Background Art

[0002] In order to adapt to market changes, the 5.4mm*90mm thin soft pack hardened product was born; since the original design of the standard cigarette package size is: 86*54.5*22.5mm, and the new product thin soft pack hardened cigarette package size is: 92*54.5*11.5mm; this will result in the number of cigarette packages in the cigarette package conveying channel to increase by nearly 1 times (the number of conventional soft pack cigarette packages is 56 packages, and the number of thin soft pack hardened cigarette packages is 107 packages) without changing the length of the cigarette package conveying channel. According to the working principle of the cigarette package conveying channel, the indexing cam moves the roller disk of 12 rollers so that the cigarette package conveyor belt steps one time The distance is 22.5mm of the cigarette package thickness. The new specifications of products require stepping cigarette packs with a thickness of 11.5mm. Therefore, the conveying channel that was originally suitable for standard cigarette packs cannot be used for the conveying of new specifications of products. The specific problems are: due to the narrowing of the thickness of the cigarette packs, the contact area with the synchronous belt is also reduced accordingly, resulting in a decrease in the friction of the belt on the forward conveying of the cigarette packs, causing slippage; at the same time, due to the increase in the number of cigarette packs that need to be taken away in the channel, the displacement error generated during each stepping process continues to accumulate, further aggravating the accumulation of cigarette packs in the output channel; cigarette packs are seriously accumulated in the channel; they cannot be synchronously and accurately transported to the exit station of the cigarette pack conveying channel, and then synchronously turned to output by the cross turntable. Utility Model Content

[0003] The purpose of the utility model is to provide a synchronous toothed belt conveyor suitable for soft-pack hardening cigarette packs of YB25 packaging machine, which has the advantages of good grinding effect and convenient adjustment, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a synchronous toothed belt conveying device suitable for soft-pack hardened cigarette packs of YB25 packaging machine, comprising a conveying platform, a cigarette pack stopping mechanism is arranged at the upstream end of the conveying platform, synchronous toothed belts are symmetrically arranged on both sides of the conveying platform, the spacing between the synchronous toothed belts is equal to the length of the cigarette pack to be conveyed, the synchronous toothed belt is tensioned with a tensioning roller, driven with an active pulley, meshed with the synchronous toothed belt passing wheel, and a cigarette moving turntable is arranged at the downstream end of the conveying platform.

[0005] In summary, due to the adoption of the above technology, the beneficial effects of the utility model are:

[0006] The synchronous toothed belt used in the utility model has higher transmission accuracy and transmission efficiency, because its transmission relies on meshing rather than pure friction, which can ensure constant speed ratio transmission and is suitable for occasions requiring precise transmission and high-speed operation. According to actual application statistical data, the utility model solves the problem of blockage of the output wheel of the YB25 packaging machine for thin soft-pack hardened products, improves production efficiency, reduces quality risks and production costs such as raw and auxiliary material consumption, and adds a cigarette pack stop mechanism and a soft brush. The cigarette pack lateral push plate is pushed out to the left and then returns, and the cigarette pack stop mechanism pops out to limit the cigarette pack, so that the cigarette pack is not skewed in the channel, and the soft brush plays a straightening role during the movement of the cigarette pack. The combined use of the two is more conducive to the smooth and accurate transportation of the cigarette pack. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0012] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0013] The utility model provides Figure 1-4 As shown, a synchronous toothed belt conveying device suitable for soft-pack hardening cigarette packs of a YB25 packaging machine includes a conveying platform, a cigarette pack stopping mechanism III is arranged at the upstream end of the conveying platform, synchronous toothed belts are symmetrically arranged on both sides of the conveying platform, the spacing between the synchronous toothed belts is equal to the length of the cigarette pack to be conveyed, the middle section of the synchronous toothed belt is provided with a driving pulley 81 drivingly matched therewith, first tensioning rollers 95 are arranged on both sides of the driving pulley 81, the first tensioning rollers 95 are tensioned with the synchronous toothed belt, the end of the synchronous toothed belt is meshed with the synchronous toothed belt passing wheel 103 and then wound around the second tensioning roller 72, and a cigarette moving turntable 61 is arranged at the downstream end of the conveying platform.

[0014] The cigarette pack stopping mechanism III comprises a left guide block 48, a spring push rod 52, an adjusting nut 53 and a compression spring 118. One end of the compression spring 118 presses against the fixed left guide block 48, and the other end presses against the spring push rod 52. When the cigarette pack is pushed forward by the cigarette pack transverse push plate, the spring push rod retreats into the cigarette pack stopping mechanism III. At this time, the side of the cigarette pack stopping mechanism III is flush with the cigarette pack. When the cigarette pack passes through the spring push rod, the spring push rod bounces back under the action of the spring to limit the cigarette pack so that the cigarette pack cannot retreat.

[0015] The synchronous toothed belt comprises an inner synchronous toothed conveyor belt 107 and an outer synchronous toothed conveyor belt 106, and the inner synchronous toothed conveyor belt 107 and the outer synchronous toothed conveyor belt 106 are symmetrically arranged on both sides of the conveying channel.

[0016] Two cigarette removing blocks 59 are arranged on the cigarette removing rotating disk 61, and the two cigarette removing blocks 59 are arranged at 180 degrees.

[0017] The following examples illustrate a specific implementation of the present invention:

[0018] 1: Determination of pulley type and size

[0019] According to the classification of toothed belts and the economic efficiency of processing and use, we choose T10 toothed belts and pulleys. When determining the pulley parameters, in order to avoid insufficient stepping distance of cigarette packs, slight deformation caused by mutual extrusion, and considering the changes in the thickness of auxiliary materials, the thickness of the cigarette pack is 11.65mm for calculation, and its outer diameter should be:

[0020] d = hn / π

[0021] Where h is the thickness of the cigarette pack after comprehensive influence, 11.65mm, n is the roller plate, the number of rollers is 12, and the diameter d of the active pulley is 44.50mm. According to the T10 synchronous pulley size table, after rounding, the synchronous pulley of 14-T10 specification can be selected, that is, the synchronous pulley parameters with an outer diameter of 42.71mm, a pitch diameter of 44.56mm, and 14 teeth can be used to manufacture the corresponding active synchronous pulley;

[0022]

[0023] After determining the specifications of the synchronous pulleys, two synchronous toothed conveyor belts (outer side 35T10 / 2110-PAR / Z, inner side: 35T10 / 2080-PAR / Z) were customized according to the center distance of the driven pulleys at the front and rear ends, the diameter of the driving pulley, etc. At the same time, the driving wheel shaft and driving pulley, as well as the cigarette pack anti-return mechanism and soft brush on the horizontal conveying channel were improved and manufactured according to the actual situation.

[0024] Working principle (see Appendix Figure 1 ):

[0025] 1) The formed cigarette pack 47 is pushed out to the cigarette pack transverse conveying channel by the cigarette pack longitudinal push rod 7;

[0026] 2) The cigarette pack transverse push plate 115 pushes the formed cigarette pack 47 to the left, and the spring push rod 52 of the cigarette pack stop mechanism III is compressed. When the formed cigarette pack 47 passes the spring push rod 52, the cigarette pack transverse push plate 115 retreats, and the compression spring 118 ejects the spring push rod 52, thereby restricting the formed cigarette pack 47 from retreating, and the cigarette pack transverse push plate 115 retreats to wait for the next cigarette pack push;

[0027] 3) When the cigarette pack transverse push plate 115 starts to push the formed cigarette pack 47 to the left, the driving pulley 81 drives the outer synchronous toothed conveyor belt 106 and the inner synchronous toothed conveyor belt 107 to move 11.5 mm, and the formed cigarette pack 47 just stops at the cigarette pack limit plate 19, and then the driving pulley stops moving;

[0028] 4) As soon as the driving pulley 81 stops, the cigarette shifting turntable 61 rotates 180 degrees clockwise, and the cigarette bale shifting block 59 shifts the formed cigarette bales 47 away from the passage. Another cigarette bale shifting block 59 waits to shift the next pack of cigarettes. The cigarette shifting turntable 61 shifts 2 packs of cigarettes per rotation.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
