Description

Technical Field

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

[0002] Gauze is a thin 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 gauze layers and thickness in different fields, 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.

[0003] For example, the Chinese utility model patent with patent number 201721621861.7 (authorization announcement number CN207483021U) discloses a "Gauze folding machine for mask production", which includes a device body, which is composed of a holding frame, a folding device and a guide shaft. A discharge rod is arranged at the front end of the guide shaft, a rotating shaft is arranged at the bottom end of the discharge rod, and the rotating shaft is located on the upper side of the holding frame. There are two guide shafts, and gears are arranged at the bottom ends of the two guide shafts. The gears are slidably connected, and the bottom ends of the gears are connected to the motor. A folding device is arranged on one side of the guide shaft, a folding plate is arranged on the upper side of the folding device, and rings are arranged at the four corners of the folding plate. A first pressing wheel is arranged on one side of the folding device, and a second pressing wheel is arranged on one side of the first pressing wheel. The first pressing wheel and the second pressing wheel are located on the upper side of the bracket. The gauze folding machine for mask production can gradually fold the transmitted gauze through the folding plate, and finally the first pressing wheel and the second pressing wheel roll the gauze that has been folded into shape, so as to avoid deviation in the folding.

[0004] However, this type of solution is only applicable to 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, the "Gauze Trifolding Machine" disclosed in the Chinese utility model patent with patent number 201921582130.5 (authorization announcement is CN210795206U) can achieve 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.

[0005] However, this type of folding mechanism also has certain shortcomings: due to the structural limitations of the folding mechanism, if the specifications or folding dimensions of the gauze to be folded change, the relative positions of the first folding plate and the second folding plate often need to be adjusted accordingly, making the entire adjustment process very cumbersome.

[0006] Therefore, how to provide a mold changing mechanism for a gauze folding machine that can quickly replace the template for gauze placement and positioning to adapt to different gauzes is a problem that those skilled in the art urgently need to solve. Utility Model Content

[0029] In order to optimize the overall structure of the locking device 3 and make the unlocking operation of the locking device 3 simpler and more convenient, Figures 4 to 7 As shown, in this embodiment, the second lock plate 3b is fixed to the upper part of the base plate 1 and presses one side portion of the template 2, the first lock plate 3a is pressed on the other side portion of the template 2 and can be moved laterally outward relative to the template 2 to detach from the template 2, and when the first lock plate 3a is in the outwardly moved and unlocked state, the template 2 can be detached from the base plate 1 and replaced as needed.

[0030] Secondly, in order to better drive the first lock plate 3a to move, so that the first lock plate 3a can be quickly unlocked, refer to Figure 1 and Figure 3 As shown, in this embodiment, the locking device 3 also includes a slider 3c installed at the bottom of the first lock plate 3a, and a slide groove 1a is provided on the bottom plate 1 for the slider 3c to slide laterally. The first lock plate 3a is driven to separate from the template 2 by driving the slider 3c to move toward the outside of the slide groove 1a.

[0031] In addition, in order to enable the slider 3c in the sliding state to be quickly locked in the slide groove 1a, refer to Figure 5 and Figure 6As shown, in this embodiment, the locking device 3 also includes a handle 3d that can lock the slider 3c on the base plate 1, and the handle 3d is provided with a screw 3d1. The slider 3c is penetrated by a through hole 3c1 for the screw 3d1 to pass horizontally, and the base plate 1 is also provided with a screw hole 1b for the screw 3d1 to be threadedly connected. By rotating the handle 3d, the slider 3c is driven to move toward the inside of the slide groove 1a, so that the slider 3c is pressed and fixed in the slide groove 1a.

[0032] At the same time, in order to make the first lock plate 3a slide more smoothly during the sliding process, in the present embodiment, two sliders 3c and two handles 3d are provided, and each slider 3c and handle 3d is spaced apart in a direction perpendicular to the moving direction of the slider 3c. Of course, we can also set more sliders 3c and handles 3d as needed.

[0033] In this embodiment, in order to make the first locking plate 3a and the second locking plate 3b better lock the template 2, refer to Figures 5 to 7 As shown, first inclined surfaces 2b inclined outward from top to bottom are specially provided on both sides of the template 2 for pressing the first lock plate 3a or the second lock plate 3b, and second inclined surfaces 3a1 which can adapt to the first inclined surfaces 2b are formed on the first lock plate 3a and the second lock plate 3b.

[0034] In this embodiment, in order to make the template 2 move back and forth only in a set direction, so as to facilitate the locking or unlocking of the template 2, refer to Figure 3 , Figure 5 and Figure 7 As shown, a limiting column 1c is protruding from the base plate 1, and a limiting groove 2f is opened on the template for the limiting column 1c to slide laterally. When the template 2 is in a moving and unlocked state, the limiting column 1c slides laterally along the limiting groove 2f to make the first inclined surface 2b of the template laterally separate from the second inclined surface 3a1.

[0035] In this embodiment, in order to better position the gauze A to be folded on the template, refer to Figure 2 and Figure 3 As shown, the template 2 is also provided with a plurality of spike-shaped positioning posts 2c facing upwards. When the gauze A to be folded is placed on the unloading station 2a, the positioning posts 2c can pass through the gauze A to be folded from bottom to top so that the gauze A to be folded is fixed on the template 2.

[0036] In this embodiment, in order to optimize the overall structure of the template 2 so that it can be placed more conveniently on the bottom plate 1, refer to Figure 2 and Figure 3As shown, in this embodiment, the two sides of the template 2 perpendicular to the moving direction of the slider 3c are formed with downwardly folded edges 2d, and the connection between the folded edges 2d and the template 2 is provided with hollow portions 2e for convenient grasping of the gauze A to be folded, and at least two hollow portions 2e are formed on each side.

The side portion of the bottom plate 1 with the slide groove 1a passes through the groove 4a1 from the inside to the outside and is exposed to the first side plate 4a. When the template 2 is installed on the top of the bottom plate 1, the two folded edges 2d will be respectively located on the outside of the two second side plates 4b and a spacing will be formed between the corresponding second side plates 4b. The formation of the spacing is conducive to the clamping member extending into the hollow portion 2e to quickly clamp the gauze A to be folded, thereby performing the subsequent folding process.

[0038] It is necessary to explain additionally here that in the present embodiment, since a template 2 which can be quickly separated is provided on the base plate 1, and the template 2 has a discharge station 2a adapted to place and position the gauze A to be folded, and a locking device 3 which can quickly lock the template 2 on the base plate 1 is provided, the locking device 2 has a first locking plate 2a and a second locking plate 2b which can respectively press the two opposite sides of the template 2. When it is necessary to fold gauze of different specifications or sizes, we only need to drive the first locking plate 2a to move relative to the template 2 and separate the first locking plate 2a from the template 2, so that the template 2 locked on the base plate 1 can be instantly unlocked, so that the template 2 adapted to the specifications or sizes of the gauze A to be folded can be quickly replaced, and the template 2 can be quickly locked by pulling the handle 3d, which effectively solves the disadvantage of the inconvenience of adjustment when the specifications or folding sizes of the gauze A to be folded change in the prior art, thereby greatly simplifying the adjustment process, and also improving the overall working efficiency of the gauze folding machine.
