AI Technical Summary
[0003]在现有技术中，需要将内筒的两端进行前后朝向的摆放，摆放完成后再由传送带将其送往下个加工环节，但在运送过程中，容易出现部分内筒因为刮擦侧壁导致速度降低，同一直线上的其他内筒就会“追上”并发生碰撞，进而造成其中一个内筒端部翘起，发生内筒堆叠的现象，此时堆叠的内筒就不符合下个环节内筒机械化加工的排布要求，因此亟需一种能够有效限制内筒运送过程中发生高度变化并高效有序的送料技术方案
[0011]与现有技术相比，本实用新型的有益效果为：通过限位机构和过筒通道，将单个内筒呈直线依次排列在传送带上，并且为了解决传送过程中发生内筒上下搭放或堆叠的问题，设置有分筒件将已经发生搭放或堆叠的内容继续有序拨分，将其恢复呈前后呈一定间距的位置分布，提高后续加工效率和准确度。

Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of fireworks inner tube processing equipment, specifically an inner tube limiting and feeding mechanism. Background Technology
[0002] Paper tube fireworks consist of an inner tube and an outer tube. The inner tube is filled with mud powder and bright bead effect powder. During the production of paper tube fireworks, the above materials need to be efficiently loaded into the inner tube through mechanized processing, which requires the inner tube to be arranged and sorted in an orderly manner in advance.
[0003] In existing technologies, the two ends of the inner cylinder need to be placed facing forward and backward. After placement, the inner cylinder is then transported to the next processing stage by a conveyor belt. However, during transportation, some inner cylinders may slow down due to scraping the side walls, causing other inner cylinders on the same straight line to "catch up" and collide. This can cause one end of the inner cylinder to lift up, resulting in the stacking of inner cylinders. At this time, the stacked inner cylinders do not meet the arrangement requirements of the mechanized processing of inner cylinders in the next stage. Therefore, there is an urgent need for a feeding technology that can effectively limit the height changes of the inner cylinders during transportation and ensure efficient and orderly feeding. Utility Model Content
[0004] To address the above problems, this utility model provides an inner cylinder limiting feeding mechanism, which realizes lateral and upper / lower limiting during the inner cylinder transportation process, ensuring that only a single inner cylinder is transported on the conveyor belt to meet subsequent processing requirements.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An inner cylinder limiting and feeding mechanism includes an inner cylinder conveyor belt horizontally mounted on a frame; a uniformly spaced cylinder passage is provided above the inner cylinder conveyor belt, and a limiting mechanism and a cylinder dividing component are provided above the cylinder passage for limiting the arrangement of the inner cylinders; the limiting mechanism has a cylinder outlet at the front end of the cylinder passage, and a cylinder height limiting plate is provided directly above the cylinder outlet, the distance between the bottom of the cylinder height limiting plate and the upper surface of the inner cylinder conveyor belt is greater than the cross-sectional diameter of the inner cylinder but less than twice the cross-sectional diameter of the inner cylinder; the cylinder dividing component has a cylinder dividing shaft horizontally mounted above the middle section of the cylinder passage, a cylinder dividing wheel is sleeved on the cylinder dividing shaft, the outer edge of the cylinder dividing wheel has a protrusion, the distance between the lowest point of the front end of the protrusion and the upper surface of the inner cylinder conveyor belt is less than the cross-sectional diameter of the inner cylinder, and the two ends of the cylinder dividing shaft are rotatably connected to the frame through connecting seats.
[0006] As a further improvement to the above solution, the height limiting plate of the cylinder is provided with a guide slope at the end away from the cylinder outlet, and the guide slope is located on the bottom surface of the height limiting plate of the cylinder; the higher end of the guide slope is away from the cylinder outlet, and the lower end of the guide slope is close to the cylinder outlet.
[0007] As a further improvement to the above solution, the cylinder height limiting plate is provided with an outlet inclined side at one end near the outlet. The outlet inclined side is located on the bottom surface of the cylinder height limiting plate, with the higher end of the outlet inclined side close to the outlet and the lower end of the outlet inclined side away from the outlet.
[0008] As a further improvement to the above solution, the limiting mechanism also includes a stop block and a limiting roller arranged laterally above the middle section of the cylinder channel; the two ends of the stop block are fixedly connected to the frame, and the two ends of the limiting roller are movably connected to the frame through roller shafts.
[0009] As a further improvement to the above solution, the distance between the bottom surface of the stop block and the upper surface of the inner cylinder conveyor belt is greater than the diameter of the inner cylinder cross-section but less than twice the diameter of the inner cylinder cross-section; the distance between the lowest point of the limiting roller and the upper surface of the inner cylinder conveyor belt is greater than the diameter of the inner cylinder cross-section but less than twice the diameter of the inner cylinder cross-section.
[0010] As a further improvement to the above solution, the inner cylinder conveyor belt includes a drive shaft driven to rotate by a drive motor, and a base belt is sleeved on the drive shaft and positioned directly below the drive shaft; the bottom of the frame is provided with support feet at the grounding point.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: through the limiting mechanism and the cylinder passage, the individual inner cylinders are arranged in a straight line on the conveyor belt. In order to solve the problem of the inner cylinders overlapping or stacking during the conveying process, a cylinder separating component is provided to continue to orderly separate the contents that have overlapped or stacked, and restore them to a position with a certain distance between them, thereby improving the efficiency and accuracy of subsequent processing.

The distance between the lowest point of the movement of the front end of the protrusion 411 and the upper surface of the inner cylinder conveyor belt 2 is less than the diameter of the inner cylinder section. The two ends of the cylinder dividing shaft 42 are rotatably connected to the frame 1 through the connecting seat 43.
[0017] like Figures 1-2 As shown, in a preferred embodiment, the height limiting plate 32 of the cylinder is provided with a guide slope 321 at the end away from the outlet 33, and the guide slope 321 is located on the bottom surface of the height limiting plate 32 of the cylinder; the higher end of the guide slope 321 is away from the outlet 33, and the lower end of the guide slope 321 is close to the outlet 33.
[0018] like Figures 1-2 As shown, in a preferred embodiment, the cylinder height limiting plate 32 is provided with an outlet inclined side 331 at one end near the outlet 33. The outlet inclined side 331 is located on the bottom surface of the cylinder height limiting plate 32. The higher end of the outlet inclined side 331 is close to the outlet 33, and the lower end of the outlet inclined side 331 is far away from the outlet 33.
[0019] like Figures 1-2 As shown, in a preferred embodiment of the above, the limiting mechanism 3 further includes a stop block 31 and a limiting roller 34 that are laterally arranged above the middle section of the cylinder channel 24; the two ends of the stop block 31 are fixedly connected to the frame 1, and the two ends of the limiting roller 34 are movably connected to the frame 1 through the roller shaft 35.
[0020] like Figures 1-2 As shown, in a preferred embodiment, the distance between the bottom surface of the stop block 31 and the upper surface of the inner cylinder conveyor belt 2 is greater than the diameter of the inner cylinder cross-section but less than twice the diameter of the inner cylinder cross-section; the distance between the lowest point of the limiting roller 34 and the upper surface of the inner cylinder conveyor belt 2 is greater than the diameter of the inner cylinder cross-section but less than twice the diameter of the inner cylinder cross-section.

At this time, the inner cylinders stacked above or behind are blocked by the height of the cylinder separating wheel 41 until the inner cylinder in front completely passes under the cylinder separating wheel 41. Finally, the two originally stacked inner cylinders are restored to a position with a certain distance between them.
