Description

Technical Field

[0001] This invention relates to a refill production apparatus, and more specifically to an automatic refill overlapping mechanism. Background Technology

[0002] Band-aids are a common item in daily life. Their main function is to help people recover from injuries by applying them to the injured area, thereby increasing the speed of wound healing and achieving effective hemostasis.

[0003] The existing structure of bandages includes an outer packaging and an adhesive core. The adhesive core consists of a bandage, a hemostatic pad, and a protective sheet. The protective sheet and the outer bandage wrap the hemostatic pad inside. The entire adhesive core is then fixed into a sheet shape by folding the outer bandage. Currently, the folding process is mainly done manually. On the one hand, the folding process is relatively complex, so manual folding often results in incorrect folding steps. On the other hand, manual folding is also prone to curling, which increases the product defect rate. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an automatic core overlapping mechanism that can effectively improve the product qualification rate.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic bandage overlapping mechanism, comprising a folding table, a pulling claw, and a folding assembly. The pulling claw is disposed on one side of the folding table for pulling up the bandage and placing it on the folding table. The folding assembly is disposed on the folding table for folding the bandage to form a bandage.

[0006] As a further improvement of the present invention, the folding assembly includes a folding plate, a clamping plate, a pusher plate, and a side folding plate. The folding plate is rotatably disposed on the side of the folding table facing the shearing table, for folding the bandage over the protective sheet. The clamping plate is vertically disposed above the folding table. The pusher plate is vertically disposed below the folding table, for lifting and feeding the bandage into the clamping plate. The side folding plate is rotatably disposed on the side of the folding table away from the shearing table, for folding the edge of the bandage. During folding, the pull claw pulls the bandage and places it on the folding table. The side folding plate flips upward to fold the bandage edge and then resets, conveying the hemostatic sheet and the protective sheet onto the bandage. The folding plate flips upward to fold the bandage over the protective sheet and then resets. The side folding plate flips upward to press down on the bandage edge. Then the clamping plate descends to the position of the bandage. After that, the pusher plate rises to push the bandage into the clamping plate. The clamping plate action folds the bandage a second time to form the dressing core.

[0007] As a further improvement of the present invention, the clamp includes a lifting bracket, a clamp seat, a left plate body, and a right plate body. The lifting bracket is vertically fixedly installed on the folding table, and the clamp seat is installed on the lifting bracket to move up and down on the folding table. A clamping cylinder is fixedly installed on the clamp seat, and the push rod of the clamping cylinder extends into the clamp seat. The left plate body and the right plate body are hinged to each other and installed on the clamp seat, and are linked with the push rod of the clamping cylinder to form a downward-opening clamp structure.

[0008] As a further improvement of the present invention, a left linkage plate and a right linkage plate are respectively bent and extended on the upper side of the left plate and the right plate, wherein the included angle between the left plate and the left linkage plate is smaller than the included angle between the right plate and the right linkage plate. A fixed column is fixed in the clamping plate seat. The side of the left linkage plate facing away from the left plate is connected to the fixed column, and the side of the right linkage plate facing away from the right plate is connected to the push rod of the clamping cylinder.

[0009] As a further improvement of the present invention, the side folding plate includes a side plate body, two side cylinders and side gears. The two side gears are rotatably mounted on both ends of the side of the folding platform facing away from the folding plate. The two ends of the side plate body are eccentrically fixed to the end faces of the two side gears. The push rods of the two side cylinders are each equipped with a rack, and the two racks mesh with the two side gears respectively.

[0010] As a further improvement of the present invention, the pulling claw includes a claw bar and a claw head. The claw bar is slidably mounted on an external frame, and the claw head is rotatably disposed on the end of the claw bar facing the folding table. A claw cylinder is fixed on the end of the claw bar, and the claw head is connected to the push rod of the claw cylinder.

[0011] As a further improvement of the present invention, the pulling claw includes a claw bar and a claw head. The claw bar is slidably mounted on an external frame, and the claw head is rotatably disposed on the end of the claw bar facing the folding table. A claw cylinder is fixed on the end of the claw bar, and the claw head is connected to the push rod of the claw cylinder.

[0012] The beneficial effect of this invention is that, by setting up the pull claw, the bandage can be effectively pulled up as a base, and then after the protective sheet and hemostatic sheet are placed on it, the folding component can effectively achieve the effect of automatic folding, thus greatly reducing the product defect rate.

[0017] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0018] Reference Figures 1 to 4 As shown, an automatic bandage core overlapping mechanism of this embodiment includes a folding table 1, a pulling claw 2, and a folding component 3. The pulling claw 2 is disposed on one side of the folding table 1 and is used to pull the bandage and place it on the folding table 1. The folding component 3 is disposed on the folding table 1 and is used to fold the bandage to form a bandage core. With the above structure, the bandage can be transported by pulling the bandage with the pulling claw 2, and the bandage core can be produced by the folding action of the folding component 3. This makes the overall bandage transport process more compact and enables better production of bandage cores.

[0019] As one specific embodiment of the improvement, the folding assembly 3 includes a folding plate 31, a clamping plate 32, a pusher plate 34, and a side folding plate 33. The folding plate 31 is rotatably disposed on the side of the folding table 1 facing the shearing table 233, for folding the bandage over the protective sheet. The clamping plate 32 is vertically and vertically disposed above the folding table 31. The pusher plate 34 is vertically and vertically disposed below the folding table 31, for lifting and feeding the bandage into the clamping plate 32. The side folding plate 33 is rotatably disposed on the side of the folding table 1 facing away from the shearing table 233, for folding the edge of the bandage. During folding, the pull claw 2 pulls the bandage and places it onto the shearing table 233. On the folding table 1, the side folding plate 33 flips upward to fold the bandage edge and then resets, conveying the hemostatic patch and protective patch onto the bandage. The folding plate 31 flips upward to fold the bandage over the protective patch and then resets. The side folding plate 33 flips upward to press down on the bandage edge. Then, the clamping plate 32 descends to the position of the bandage. After that, the push plate 34 rises to push the bandage into the clamping plate 32. The clamping plate 32 folds the bandage a second time to form the dressing core. With the above structure, the bandage with the protective patch and hemostatic patch placed can be folded stably and reliably to form the dressing core. In addition, certain edge pressing and pressing operations are performed during the folding process to effectively ensure the accuracy of the folding part and folding action.

[0020] As an improved specific implementation, the clamping plate 32 includes a lifting bracket 321, a clamping plate base 324, a left plate body 322, and a right plate body 323. The lifting bracket 321 is vertically fixedly installed on the folding table 1. The clamping plate base 324 is installed on the lifting bracket 321 to move up and down on the folding table 1. A clamping cylinder 325 is fixedly installed on the clamping plate base 324. The push rod of the clamping cylinder 325 extends into the clamping plate base 324. The left plate body 322 and the right plate body 323 are hinged to each other and installed on the clamping plate base 324, and are linked with the push rod of the clamping cylinder 325 to form a downward-opening clamping structure. Through the above structure, the clamping cylinder 325 can be effectively configured as a clamping force provider, thereby better realizing the secondary folding of the core.

[0021] As an improved specific implementation, the upper sides of the left plate 322 and the right plate 323 are respectively curved and extended with a left linkage plate 326 and a right linkage plate 327, wherein the included angle between the left plate 322 and the left linkage plate 326 is smaller than the included angle between the right plate 323 and the right linkage plate 327. A fixed column 328 is fixed inside the clamping plate seat 324. The side of the left linkage plate 326 facing away from the left plate 322 is connected to the fixed column 328, and the side of the right linkage plate 327 facing away from the right plate 323 is connected to the push rod of the clamping cylinder 325. With the above structure, the linkage between the left plate 322 and the right plate 323 and the clamping cylinder 325 can be realized simply and effectively.

[0022] As an improved specific implementation, the side folding plate 33 includes a side plate body 331, two side cylinders 333, and side gears 332. The two side gears 332 are rotatably mounted on both ends of the side of the folding table 1 facing away from the folding plate 31. The two ends of the side plate body 331 are eccentrically fixed to the end faces of the two side gears 332. Each of the push rods of the two side cylinders 333 is equipped with a rack, and the two racks mesh with the two side gears 332 respectively. With the above structure, the side cylinders 333 can be used to push the side plate body 331 to flip, which can effectively ensure the flipping stroke and increase the flipping speed.

[0023] As an improved specific implementation, the pull claw 2 includes a claw bar 21 and a claw head 22. The claw bar 21 is slidably mounted on an external frame, and the claw head 22 is rotatably disposed on the end of the claw bar 21 facing the folding table 1. A claw cylinder 23 is fixed on this end of the claw bar 21, and the claw head 22 is connected to the push rod of the claw cylinder 23. With the above structure, the pull claw 2 can be effectively constructed, and the overall structure is simple.

[0024] As an improved specific implementation, a discharge conveyor belt 4 is slidably provided above the pull claw 2. Both ends of the discharge conveyor belt 4 are provided with inclined discharge grooves 5, so that when the clamping plate 32 rises, the discharge conveyor belt 4 slides toward the folding table 1 to place the discharge grooves 5 at the ends below the clamping plate 32, and then slides back to its original position. With the above structure, it can play a role in receiving the core after the clamping plate 32 rises and completes the second fold, so that the clamping plate 32 does not need to be displaced in the horizontal direction, effectively increasing the overall production efficiency.

[0025] In summary, the overlapping mechanism of this embodiment achieves automated folding of the adhesive core through the cooperation of the folding component 3, the pull claw 2, and the folding table 1, effectively reducing the defect rate of the adhesive core.
