Description

Technical Field

[0001] The utility model relates to the technical field of gauze production equipment, in particular to a stacking mechanism of a gauze folding machine. Background Art

[0002] Gauze is a thin and light silk fabric with sparse warp and weft. Gauze comes in various varieties and is widely used in industrial and medical fields. According to the requirements of the number of gauze layers and thickness in different fields, the gauze usually needs to be folded. Medical absorbent gauze is a necessary consumable used in hospitals and even in people's daily lives, and the amount used is huge. Due to the particularity of its use and the increasingly high quality requirements, especially for export products, the quality requirements are higher, so the processing technology requirements are becoming more and more stringent. During the production of medical absorbent gauze, the gauze is usually folded by a folding device to obtain the product. Among them, the earliest gauze folding machine is generally only suitable for products with one fold and two layers. As the requirements for the number of gauze layers continue to increase, the gauze folding machine for mask production mentioned above is obviously not applicable to gauze that needs to be folded into three layers or more. In order to meet the folding needs of more layers.

[0003] The "Gauze Tri-Folding Machine" disclosed in the Chinese Utility Model Patent with patent number 201921582130.5 (authorization announcement is CN210795206U) can realize three-layer folding, which includes a loading rack, a turning rack and a receiving rack. The loading rack is provided with a loading roller, the turning rack is arranged on one side of the loading rack, the turning rack is provided with a first folding plate and a second folding plate, the receiving rack is arranged on the side of the turning rack away from the receiving rack, and the receiving rack is provided with two active rollers, the two active rollers are arranged side by side and fit each other, and a receiving roller is installed on the receiving rack and between the two active rollers. The gauze can be folded into three layers in sequence by folding the first folding plate and the second folding plate in sequence.

[0004] However, this type of folding mechanism is only suitable for folding uncut whole gauze. In some specific occasions, it is often necessary to fold the pre-cut gauze to be folded into multiple layers separately, and it is also necessary to stack multiple pieces of individually folded gauze and then bundle them into a bundle for packaging. The above-mentioned folding mechanism obviously does not have the function of automatic stacking, and often requires subsequent manual stacking, which is time-consuming and labor-intensive.

[0005] Therefore, how to provide a stacking mechanism of a gauze folding machine that can automatically stack the folded gauze and make subsequent bundling and packaging more convenient is a problem that those skilled in the art urgently need to solve. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a stacking mechanism of a gauze folding machine which can automatically stack folded gauze to make subsequent bundling and packaging more convenient in view of the above technical status quo.

[0007] The technical solution adopted by the utility model to solve the above-mentioned technical problems is as follows: the stacking mechanism of the gauze folding machine includes a bottom plate and a shell arranged on the bottom plate, a feed port is formed on the top of the shell, and a lifting platform for placing the folded gauze is also provided in the shell. The lifting platform can be lifted up and down under the drive of a first driving mechanism, and the upper area of ​​the lifting platform forms a stacking space for accommodating the folded gauze. It also includes a pair of sensors arranged on both sides of the shell, and the two sensors are arranged opposite to each other and adjacent to the feed port.

When the support plate drops to the bottom of the groove, the robotic arm for grasping the stacked gauze can pass through the groove from the side of the lifting platform and grasp the folded gauze.

[0011] In order to optimize the overall structure of the second driving mechanism so that it can better drive the pallet to move up and down, preferably, the second driving mechanism is a first cylinder, which is installed at the bottom of the base plate, and the output end of the first cylinder passes through the lifting platform from bottom to top and is driven and connected to the pallet, and a second through hole is also provided on the lifting platform for the output end of the first cylinder to pass through.

The output end of the second cylinder passes through the base plate from bottom to top and is driven to be connected to the shell. A third through hole is provided on the base plate for the output end of the second cylinder to pass through from bottom to top, and the bottom of the shell also extends outward with a folded edge for connecting the output end of the cylinder.

[0014] In order to make the lifting platform and the shell better adaptable to the grasping of the robot arm, preferably, two grooves and two slots are provided, and the two grooves and the two slots are arranged at intervals and correspond to each other one by one up and down.

[0015] In order to optimize the sensing structure of the sensor so that it can more sensitively sense the falling process of the folded gauze, preferably, the sensor is a laser counter-beam sensor, and two laser counter-beam sensors are respectively installed on two brackets on both sides of the shell, and the two side walls of the shell adjacent to the feed port are also provided with corresponding laser holes.

[0016] In order to allow the folded gauze to better enter the accommodating space in the shell, preferably, the top edge of the shell extends obliquely from bottom to top toward the outer peripheral side to form a funnel-shaped guide wall.
