Description

Technical Field

[0001] This utility model relates to the field of packaging bag production technology, specifically to a stable and durable packaging bag conveying device with adjustable clearance. 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] The aforementioned patents are highly practical and have excellent effects. 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 stable and durable packaging bag conveying device with adjustable clearance, which can not only realize the clearance 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 stable and durable, adjustable bag conveyor, comprising a belt conveyor and a branch 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 rotatably mounted on the drive roller mounting frame. Each drive roller has several belt grooves, with the number of belt grooves on each drive roller exceeding the number of conveyor belts. The conveyor belts include a protrusion, a belt body, and an embedded part. The protrusion is located on the outer surface of the belt body and extends along the length of the belt body. The embedded part is located on the inner surface of the belt body and extends along the length of the belt body. The conveyor belts pass around the drive rollers, and the embedded parts of the conveyor belts are embedded in the belt grooves.

[0009] The dividing baffle is vertically installed above the belt conveyor and is parallel to the conveying direction of the belt conveyor. The dividing baffles are arranged opposite each other to separate the dividing conveying 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.

[0010] As a preferred technical solution, the conveyor belt body is a flat belt with a rectangular cross-section.

[0011] As a preferred technical solution, the protrusion of the conveyor belt is a semi-circular belt with a semi-circular cross-section.

[0012] As a preferred technical solution, the embedded part of the conveyor belt is a semi-circular belt with a semi-circular cross-section.

[0013] As a preferred technical solution, the protrusions, belt body and embedded part of the conveyor belt are integrally formed or bonded together.

[0014] As a preferred technical solution, the number of belt grooves on each drive roller is 2-5 times the number of conveyor belts.

[0015] As a preferred technical solution, the packaging bag 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, and the branch baffle is movably mounted on the baffle mounting beam along the axial direction of the baffle mounting beam.

[0016] As a preferred technical solution, when the conveyor belt needs to be adjusted, it is transferred to a nearby excess belt trough.

[0017] The beneficial effects of this utility model are as follows:

[0018] In this invention, the number of belt grooves on each drive roller is greater than the number of conveyor belts. The conveyor belts bypass the drive rollers, and the embedded part of the conveyor belts is embedded in the belt grooves. Therefore, it can achieve the same technical effect as the prior patent CN112758718B: 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 offset and leakage of packaging bags 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 a nearby excess belt groove, realizing the yielding adjustment of a single conveyor belt.

[0019] Meanwhile, this utility model features a special design for the shape and structure of the conveyor belt. The conveyor belt includes a protrusion, a belt body, and an insert. The protrusion is located on the outer surface of the belt body and extends along the length of the belt body, while the insert is located on the inner surface of the belt body and extends along the length of the belt body. The insert of the conveyor belt is used to embed itself into the belt groove to limit the movement of the conveyor belt and facilitates the transfer and repositioning of the conveyor belt between the belt grooves. Since the belt body is not limited by the width of the belt groove, its width can be increased, thereby improving the support for the packaging bag, enhancing the conveying stability of the packaging bag, preventing the conveyor belt from twisting and deforming, and slowing down the loosening of the conveyor belt due to fatigue deformation, thus greatly improving the service life of the conveyor belt. The protrusion of the conveyor belt is used to solve the problem of the packaging bag sticking flat and adhering to the belt body, so that the packaging bag can be smoothly discharged at the end of the belt conveyor.

[0026] 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.

[0027] like Figures 1 to 5 The present invention discloses a stable and durable adjustable packaging bag conveyor, which includes a belt conveyor and a branch baffle 1.

[0028] 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 belt grooves 5, and the number of belt grooves 5 on each drive roller 2 is greater than the number of conveyor belts 4. The conveyor belt 4 includes a protrusion 43, a belt body 41, and an embedded part 42. The protrusion 43 is disposed on the outer surface of the belt body 41 and extends along the length of the belt body 41. The embedded part 42 is disposed on the inner surface of the belt body 41 and extends along the length of the belt body 41. The conveyor belt 4 passes around the drive rollers 2, and the embedded part 42 of the conveyor belt 4 is embedded in the belt groove 5.

[0029] When the number and density of belt grooves 5 on the drive roller 2 are large, it facilitates the adjustment of the conveyor belt 4. Preferably, the number of belt grooves 5 on each drive roller 2 is 2-5 times the number of conveyor belts 4.

[0030] The embedding part 42 of the conveyor belt 4 is used to embed into the belt groove 5 to limit the position of the conveyor belt 4, and also facilitates the transfer and repositioning of the conveyor belt 4 between the belt grooves 5; since the belt body 41 is not limited by the width of the belt groove 5, its width can be increased, thus improving the support for the packaging bag, improving the conveying stability of the packaging bag, and also preventing the conveyor belt 4 from twisting and deforming, slowing down the loosening of the conveyor belt 4 due to fatigue deformation, and greatly improving the service life of the conveyor belt 4; the protrusion 43 of the conveyor belt 4 is used to solve the problem of the packaging bag sticking flat and adhering to the belt body 41, so that the packaging bag can be smoothly discharged at the end of the belt conveyor.

[0031] like Figure 5 As shown, the conveyor belt 4's main body 41 can be designed as a flat belt with a rectangular cross-section, the embedded part 42 of the conveyor belt 4 can be designed as a semi-circular belt with a semi-circular cross-section, and the protrusion 43 of the conveyor belt 4 can be designed as a semi-circular belt with a semi-circular cross-section. In practical applications, the protrusion 43, the main body 41, and the embedded part 42 of the conveyor belt 4 can be integrally formed or bonded together.

[0032] 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 positioned opposite each other to create dividing conveyor channels. The bottom of each 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 particular dividing baffle 1 at the position of a certain conveyor belt 4, the conveyor belt 4 needs to be adjusted to make way. In this case, the conveyor belt 4 can be moved to a nearby spare belt trough 5.

[0033] As one of the ways to install and move the diversion baffle 1, the packaging bag 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.

[0034] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention. The scope of protection of the present invention is defined by the claims.
