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 with a correction function. Background Technology

[0002] In the traditional packaging bag production process, after the bags are produced by the bag-making machine, they are manually counted, stacked, and bundled. This process is costly, inefficient, and makes it difficult to guarantee the accuracy of counting and the effectiveness of bundling. Therefore, the applicant of this utility model has invented a bag sorting machine that automates and mechanizes the stacking, sorting, and bundling of packaging bags.

[0003] Bag sorting machines typically have a dividing baffle above the conveying mechanism to guide and limit the movement of packaging bags during transport. For example, in a prior invention patent application CN201910528030.2 filed by the applicant of this utility model, a dividing baffle is installed above the conveying mechanism, with the dividing baffles positioned opposite each other to create a dividing conveying channel. Packaging bags cut by the upstream bag making machine are conveyed into the dividing conveying channel.

[0004] To ensure smooth transport of packaging bags within the distribution conveyor channel, the channel width is typically adjusted to be slightly larger than the width of the packaging bags. However, packaging bags cut from the upstream bag-making machine may enter the distribution conveyor channel at an angle, causing them to be transported forward at a skewed posture. In severe cases, they may even be transported forward with their length and width sides rotated by 90°, posing a risk of material jamming or uneven stacking downstream. The skewed packaging bags may be caused by machine vibration, especially in bag-making machines equipped with die-cutting mechanisms, which experience greater vibration during bag cutting, thus increasing the risk of skewed packaging bags entering the distribution conveyor channel. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a packaging bag diversion and conveying device with a correction function, which can correct skewed packaging bags during conveying.

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

[0007] A packaging bag diversion and conveying device with a correction function is disclosed. The packaging bag diversion and conveying device includes a conveying mechanism, diversion baffles, and a correction component. The diversion baffles are vertically arranged above the conveying mechanism and are parallel to the conveying direction of the conveying mechanism. The diversion baffles are arranged opposite to each other to separate diversion and conveying channels. The correction component includes a baffle rod and a lifting drive mechanism. The baffle rod is vertically arranged above the feed end of the conveying mechanism and extends into the diversion and conveying channel. The lifting drive mechanism is used to drive the baffle rod to move up and down.

[0008] As a preferred technical solution, the transmission mechanism is a belt conveyor, which includes a drive roller and several conveyor belts. The conveyor belts pass around the drive roller and are arranged in parallel intervals. When the lifting drive mechanism drives the stop bar to descend, the bottom of the stop bar extends from the gap between the conveyor belts into the transmission surface of the conveyor belt.

[0009] As a preferred technical solution, the packaging bag diversion and transmission device further includes a baffle mounting beam that spans above the transmission mechanism and is perpendicular to the transmission direction of the transmission mechanism. The diversion baffle is movably mounted on the baffle mounting beam along the axial direction of the baffle mounting beam.

[0010] As a preferred technical solution, the packaging bag branching and conveying device further includes a correction mounting beam that spans above the conveying mechanism and is perpendicular to the conveying direction of the conveying mechanism, and the correction component is movably mounted on the correction mounting beam along the axial direction of the correction mounting beam.

[0011] As a preferred technical solution, the correction mounting beam is slidably engaged with the transmission mechanism along the transmission direction of the transmission mechanism via a sliding mechanism.

[0012] As a preferred technical solution, the lifting drive mechanism is a cylinder, a hydraulic cylinder, an electric cylinder, a gear and rack transmission mechanism, a nut and screw mechanism, or a linear motor.

[0013] As a preferred technical solution, each branch transmission channel is equipped with one or more material stop bars.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention adds a correction component to the packaging bag distribution and conveying device. The baffle rod of the correction component is vertically positioned above the feed end of the conveying mechanism and extends into the distribution and conveying channel. When the packaging bags cut by the upstream bag making machine enter the distribution and conveying channel, the baffle rod descends to block the packaging bags. The packaging bags collide with the baffle rod, and under the combined action of the left and right side distribution baffles and the front baffle rod, the skewed packaging bags are corrected. Then the baffle rod rises again, and the packaging bags continue to be conveyed forward. Therefore, this invention achieves the purpose of correcting skewed packaging bags during conveying. Attached Figure Description

[0016] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the following drawings are provided for illustration:

[0017] Figure 1 A schematic diagram of the packaging bag distribution and conveying device (with the baffle bar in the lowered state);

[0018] Figure 2This is a schematic diagram of the packaging bag distribution and conveying device (with the baffle bar raised). Detailed Implementation

[0019] 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.

[0020] like Figure 1 and Figure 2 The diagram illustrates a packaging bag diversion and conveying device with a correction function. The packaging bag diversion and conveying device includes a conveying mechanism 1, a diversion baffle 2, and a correction component. The diversion baffle 2 is vertically arranged above the conveying mechanism 1 and is parallel to the conveying direction of the conveying mechanism 1. The diversion baffles 2 are arranged opposite each other to separate diversion and conveying channels. The correction component includes a baffle rod 3 and a lifting drive mechanism 4. The baffle rod 3 is vertically arranged above the feeding end of the conveying mechanism 1 and extends into the diversion and conveying channel. The lifting drive mechanism 4 is used to drive the baffle rod 3 to move up and down.

[0021] When the packaging bags cut by the upstream bag-making machine enter the branching conveyor channel, the baffle rod 3 descends to block the packaging bags (e.g., Figure 1 As shown), the packaging bag impacts the baffle bar 3. With the combined action of the left and right side baffles 2 and the front baffle bar 3, the tilted packaging bag is corrected; then the baffle bar 3 rises upwards (as shown). Figure 2 As shown, the packaging bag continues to be conveyed forward; thus achieving the purpose of correcting the skewed packaging bag during conveyance.

[0022] In this embodiment, the transmission mechanism 1 is a belt conveyor, which includes a drive roller and several conveyor belts 5. The conveyor belts 5 bypass the drive roller and are arranged in parallel at intervals. When the lifting drive mechanism 4 drives the baffle rod 3 to descend, the bottom of the baffle rod 3 extends below the transmission surface of the conveyor belt 5 through the gap between the conveyor belts 5. The bottom of the baffle rod 3 extending below the transmission surface of the conveyor belt 5 through the gap ensures that even very thin packaging bags will not leak through, guaranteeing a corrective effect.

[0023] The lifting drive mechanism 4 can be a conventional lifting drive mechanism such as a cylinder, hydraulic cylinder, electric cylinder, gear and rack transmission mechanism, nut and screw mechanism or linear motor. In this embodiment, the lifting drive mechanism 4 is a cylinder.

[0024] In this embodiment, each branch transmission channel is equipped with one baffle bar. Of course, depending on factors such as the width of the branch transmission channel and the packaging bag, two or more baffle bars can be set in each branch transmission channel, and the two baffle bars in one branch transmission channel can be driven by a lifting drive mechanism.

[0025] In order to enable the packaging bag branching and conveying device to adjust the width of the branching and conveying channel according to the size of the packaging bag, the packaging bag branching and conveying device also includes a baffle mounting beam 6 that spans above the conveying mechanism 1 and is perpendicular to the conveying direction of the conveying mechanism 1. The branching baffle 2 is movably mounted on the baffle mounting beam 6 along the axial direction of the baffle mounting beam 6.

[0026] Correspondingly, the correction component can also be adjusted left and right according to the adjustment of the branch transmission channel. The packaging bag branch transmission device also includes a correction mounting beam 7 that spans above the transmission mechanism 1 and is perpendicular to the transmission direction of the transmission mechanism 1. The correction component is movably mounted on the correction mounting beam 7 along the axial direction of the correction mounting beam 7.

[0027] In addition, the correction component is generally set above the feed end of the transmission mechanism 1. However, in order to facilitate the adjustment of the front and rear positions of the correction component, the correction mounting beam 7 is slidably engaged with the transmission mechanism 1 along the transmission direction of the transmission mechanism 1 through the sliding mechanism 8.

[0028] 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.
