Description

Technical Field

[0001] The utility model relates to the technical field of cigarette equipment, in particular to a height adjustment device for a conveyor belt at an inlet of a spiral channel. Background Art

[0002] The ZB416A high-speed packaging equipment for slim cigarettes can produce up to 500 packs per minute and features a high level of automation. However, this type of packaging equipment still has some mechanical deficiencies, such as the height adjustment of the conveyor belt at the entrance of the spiral channel. According to the original operating manual, when adjusting the height of the conveyor belt at the entrance of the spiral channel, it is necessary to adjust multiple components, including the product sliding platform, the position of the conveyor belt, and the input roller of the spiral stacker feed belt. This involves multiple parameters, including the relative position of the sliding platform, the relative position of the upper conveyor belt, and the height of the spiral stacker feed belt input roller. The adjustment process is complex, and there are many interlocking mechanical parts, requiring repeated adjustments of various parts to achieve mechanical coordination. Therefore, the height adjustment process of the conveyor belt at the entrance of the spiral channel is time-consuming and inefficient, seriously affecting the equipment's production capacity.

[0029] like Figures 1 to 3 As shown, the utility model provides a height adjustment device for a conveyor belt at an entrance of a spiral channel, comprising a mounting seat 100 , a height adjustment shaft 200 and a height pressing gear 300 . Among them, a mounting hole 110 is provided at one end of the mounting seat 100, and a mounting groove 120 is provided at the other end of the mounting seat 100. The mounting seat 100 is provided with a first circular hole 130 and a second circular hole 140 that are communicated with the mounting groove 120. The first circular hole 130 and the second circular hole 140 are coaxially arranged. The mounting seat 100 is threadedly connected with a locking bolt, which can be inserted into the first circular hole 130; one end of the height adjustment shaft 200 is rotatably connected to the first circular hole 130, and the locking bolt can lock the height adjustment shaft 200. The other end of the height adjustment shaft 200 is rotatably connected to the second circular hole 140. A mounting cylinder 210 is provided on the height adjustment shaft 200, and the mounting cylinder 210 is located in the mounting groove 120. The axis of the mounting cylinder 210 is parallel to the axis of the height adjustment shaft 200, and the axis of the mounting cylinder 210 does not coincide with the axis of the height adjustment shaft 200; the height clamping gear 300 is rotatably sleeved on the mounting cylinder 210.

[0030] The present invention provides a height adjustment device for the conveyor belt at the entrance of a spiral channel. The mounting base 100 is installed at the exit of the original equipment through the mounting hole 110. The outer ring of the height-compression gear 300 engages the conveyor belt at the entrance of the spiral channel. The height-compression gear 300 rotates relative to the mounting cylinder 210 as the conveyor belt rotates. Specifically, a fixing bolt passes through the mounting hole 110 and is threadedly connected to the exit of the original equipment, thereby achieving installation of the mounting base 100 at the exit of the original equipment.

[0031] During adjustment operation, the height adjustment shaft 200 is rotated to drive the mounting cylinder 210 to rotate. Since the axis of the mounting cylinder 210 is parallel to the axis of the height adjustment shaft 200, and the axis of the mounting cylinder 210 does not coincide with the axis of the height adjustment shaft 200, an eccentric structure is formed between the height adjustment shaft 200 and the mounting cylinder 210. The height of the mounting cylinder 210 changes with the rotation of the height adjustment shaft 200, thereby adjusting the height of the rotation center of the height clamping gear 300, thereby changing the clamping height of the conveyor belt at the entrance of the spiral channel, and then tightening the locking bolt to lock the height adjustment shaft 200. The whole process is simple and convenient.

[0032] In some embodiments, a connecting cylinder 220 is provided at one end of the height adjustment shaft 200. The connecting cylinder 220 is coaxially arranged with the height adjustment shaft 200 and is rotatably connected to the first circular hole 130. A locking bolt can compress the outer wall of the connecting cylinder 220. A connecting groove 221 is formed at the end of the connecting cylinder 220 away from the height adjustment shaft 200. The connecting groove 221 can be a regular pentagonal groove or a regular hexagonal groove. When rotating the height adjustment shaft 200, a wrench can be inserted into the connecting groove 221. The wrench is used to rotate the connecting cylinder 220, and the connecting cylinder 220 drives the height adjustment shaft 200 to rotate.

[0033] In some embodiments, mounting hole 110 is a strip-shaped hole, allowing the mounting base 100 to be adjusted in its position at the outlet of the original device. A slot 150 is defined at the bottom of the end of mounting base 100 near mounting hole 110. Slot 150 fits snugly against the outlet of the original device, enhancing the stability of mounting base 100. Mounting base 100 also defines a screw hole 160 that communicates with first circular hole 130, and a locking bolt is threadedly engaged with screw hole 160.

[0034] In some embodiments, the number of the mounting cylinders 210 is at least two, and the number of the height pressing gears 300 is the same as the number of the mounting cylinders 210. The height pressing gears 300 and the mounting cylinders 210 are rotatably connected via a bearing.

[0035] In some embodiments, the height compression gear 300 has 20 teeth, an outer diameter of 30.98 mm, an inner diameter of 22.00 mm, and a tooth depth of 1.25 mm. The conveyor belt height H is equal to the cigarette pack width X minus 1 mm. If the cigarette pack width X is 12.5 mm, the conveyor belt height H is 11.5 mm.

[0036] The spiral channel inlet conveyor belt height adjustment device can reduce the time spent on adjusting the height of the spiral channel inlet conveyor belt, improve production efficiency, and ensure equipment production capacity.

[0037] All standard parts used in this utility model are commercially available, and special-shaped parts can be customized according to the description in the specification and drawings. The specific connection methods of each part adopt mature methods in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology. The circuit connections adopt conventional connection methods in the existing technology and will not be described in detail here.
