Description

Technical Field

[0001] This utility model relates to the field of packaging bag production technology, specifically to a packaging bag distribution and transmission device. Background Technology

[0002] In the packaging bag production process, after the packaging bags are produced by the bag making machine, some processes involve conveying the packaging bags.

[0003] The inventor of this utility model disclosed a belt conveyor and branching transmission device with adjustable clearance in a prior invention patent application CN112758718B. In that patent, the bottom of the branching baffle extends below the transmission surface of the conveyor belt from the gap between the conveyor belts, thus neither interfering with the transmission of the belt conveyor nor leaving a gap between the bottom of the branching baffle and the transmission surface, solving the problems of packaging bag offset and leakage during the conveying process; and when adjusting the position of the branching baffle, if it is necessary to stop a certain branching baffle at the position of a certain conveyor belt, that conveyor belt can be transferred to a nearby excess belt groove, realizing the clearance adjustment of a single conveyor belt.

[0004] However, the aforementioned patents are highly practical and have excellent effects, so the inventors of this utility model have further optimized and improved them. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a packaging bag distribution and transmission device that can not only realize the yielding adjustment of a single conveyor belt, but also further improve the conveying stability of packaging bags.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A packaging bag diversion and conveying device, the packaging bag diversion and conveying device comprising a belt conveyor and a diversion baffle;

[0008] The belt conveyor includes at least two drive rollers, a drive roller mounting frame, and several conveyor belts. The drive rollers are arranged in parallel and are rotatably mounted on the drive roller mounting frame. Each drive roller has several annular arc-shaped protrusions, and the number of annular arc-shaped protrusions on each drive roller is greater than the number of conveyor belts. The conveyor belts are flat belts with a rectangular cross-section. The conveyor belts pass around the drive rollers and cover the annular arc-shaped protrusions on the drive rollers.

[0009] The dividing baffle is vertically installed above the belt conveyor and parallel to the conveying direction of the belt conveyor. The dividing baffles are arranged opposite each other to separate the dividing conveyor channels. The bottom of the dividing baffle extends from the gap between the conveyor belts into the conveying surface of the conveyor belt. The dividing baffle can move perpendicular to the conveying direction of the belt conveyor. When the conveyor belt needs to make way for adjustment, the conveyor belt is transferred to a nearby excess annular arc protrusion.

[0010] As a preferred technical solution, the number of annular arc protrusions on each drive roller is 2-4 times the number of conveyor belts.

[0011] As a preferred technical solution, the packaging bag diversion and conveying device further includes a baffle mounting beam that spans above the belt conveyor and is perpendicular to the conveying direction of the belt conveyor. The diversion baffle is movably mounted on the baffle mounting beam along the axial direction of the baffle mounting beam.

[0012] As a preferred technical solution, the width of the conveyor belt is 10-30mm, and the width of the annular arc protrusion is 10-30mm.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this invention, the number of annular arc protrusions on each drive roller is greater than the number of conveyor belts. The conveyor belts wrap around the drive rollers and cover the annular arc protrusions on the drive rollers. Therefore, the same technical effect as the prior patent CN112758718B can be achieved: the bottom of the dividing baffle extends from the gap between the conveyor belts into the transmission surface of the conveyor belt, so as not to interfere with the transmission of the belt conveyor, and not to leave a gap between the bottom of the dividing baffle and the transmission surface, thus solving the problem of packaging bag offset and leakage during the conveying process; when adjusting the position of the dividing baffle, if it is necessary to stop a certain dividing baffle at the position of a certain conveyor belt, this conveyor belt can be transferred to the nearby excess annular arc protrusion, realizing the yielding adjustment of a single conveyor belt.

[0015] Meanwhile, this utility model has made a special design to the shape and structure of the transmission roller. The conveyor belt is wrapped around the annular arc-shaped raised surface of the transmission roller to prevent the conveyor belt from shifting during operation and to facilitate the transfer and repositioning of the conveyor belt between the annular arc-shaped raised surfaces. The conveyor belt is a flat belt with a rectangular cross-section, which can improve the support for the packaging bag, improve the conveying stability of the packaging bag, and also slow down the loosening of the conveyor belt due to fatigue deformation, thus greatly improving the service life of the conveyor belt.

[0019] Figure 3 This is a schematic diagram of the transmission roller. Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0021] like Figures 1 to 3 The diagram shows a packing bag diversion and conveying device with adjustable clearance, the packing bag diversion and conveying device including a belt conveyor and a diversion baffle 1.

[0022] The belt conveyor includes at least two drive rollers 2, a drive roller mounting frame 3, and several conveyor belts 4. The drive rollers 2 are arranged in parallel and are rotatably mounted on the drive roller mounting frame 3. Each drive roller 2 has several annular arc-shaped protrusions 5. The number of annular arc-shaped protrusions 5 on each drive roller 2 is greater than the number of conveyor belts 4. The conveyor belts 4 are flat belts with a rectangular cross-section. The conveyor belts 4 pass around the drive rollers 2 and cover the surface of the annular arc-shaped protrusions 5 on the drive rollers 2.

[0023] When the number and density of the annular arc-shaped protrusions 5 processed on the drive roller 2 are large, it facilitates the adjustment of the conveyor belt 4. Preferably, the number of annular arc-shaped protrusions 5 on each drive roller 2 is 2-4 times the number of conveyor belts 4. Based on standard packaging bag sizes, the width of the conveyor belt 4 can be set to 10-30mm, and the width of the annular arc-shaped protrusions 5 can also be set to 10-30mm.

[0024] The dividing baffle 1 is vertically installed above the belt conveyor and parallel to the conveying direction of the belt conveyor. The dividing baffles 1 are arranged opposite each other to separate the dividing conveyor channels. The bottom of the dividing baffle 1 extends below the conveying surface of the conveyor belt 4 through the gap between the conveyor belts 4. The dividing baffle 1 can move perpendicular to the conveying direction of the belt conveyor to adjust the width of the dividing conveyor channels to accommodate packaging bags of different widths. When adjusting the position of the dividing baffle 1, if it is necessary to stop a certain dividing baffle 1 at the position of a certain conveyor belt 4, the conveyor belt 4 needs to make way for adjustment. At this time, the conveyor belt 4 can be transferred to a nearby excess annular arc protrusion 5.

[0025] As one of the ways to install and move the diversion baffle 1, the packaging bag diversion conveying device also includes a baffle mounting beam 6 that spans above the belt conveyor and is perpendicular to the conveying direction of the belt conveyor. The diversion baffle 1 is movably installed on the baffle mounting beam 6 along the axial direction of the baffle mounting beam 6.
