[0026] As Figure 1 shown, the disposable raincoat machine comprises a machine base 6, a front traction mechanism 4 and a raincoat forming mechanism 3. The front traction mechanism 4 is used to pull the film on the roll of film forward, so that the film reaches the raincoat forming mechanism 3, and the film completes the raincoat forming work in the raincoat forming mechanism 3, and one by one disposable raincoat 9 is made.
[0027] As Figure 2 and Figure 3 shown, the raincoat forming mechanism 3 comprises a forming base 31, a forming lifting seat 30, a lifting power source (not shown in the figure), a cutting knife 34, a heat sealing wire 35 (electric heating wire) and a heat sealing pressing plate 37. The forming base 31 is located below the forming lifting seat 30, the forming lifting seat 30 is installed on the machine base 6 in a lifting manner (realized by a lifting rod 32 on the machine base 6), and the lifting power source can drive the forming lifting seat 30 to lift up and down. Figure 6 The forming base 31 or the forming lifting seat 30 is provided with a forming cutting groove 36 (as Figure 6 shown, the forming cutting groove 36 is located on the forming base 31), the cutting knife 34 can enter the forming cutting groove 36 when the forming lifting seat 30 is lowered, the heat sealing wire 35 is arranged on the forming base 31 or the forming lifting seat 30 (as
[0028] It should be noted that the forming slot 36 can be provided on the forming base 31 or the forming lifting seat 30. When the forming slot 36 is provided on the forming base 31, the point cutting knife 34 is provided on the forming lifting seat 30; when the forming slot 36 is provided on the forming lifting seat 30, the point cutting knife 34 is provided on the forming base 31; thus, the point cutting knife 34 enters the forming slot 36 when the forming lifting seat 30 is lowered, and the film is point cut (which is an easy-to-tear line and will not be cut off). Similarly, the heat sealing wire 35 can be provided on the forming base 31 or the forming lifting seat 30. When the heat sealing wire 35 is provided on the forming base 31, the heat sealing pressing plate 37 is provided on the forming lifting seat 30; when the heat sealing wire 35 is provided on the forming lifting seat 30, the heat sealing pressing plate 37 is provided on the forming base 31; thus, the heat sealing pressing plate 37 is pressed on the heat sealing wire 35 when the forming lifting seat 30 is lowered, and the heat sealing is performed on the edge of the point cut of the film.
[0029] In operation, the film comes to the forming base 31, the point cutting knife 34 point cuts the outline of the raincoat on the film, and then the heat sealing wire 35 performs heat sealing on the edge of the point cut of the film, thereby forming one disposable raincoat after another. As shown in Figure 11 When the film uses the folded plastic film B, one disposable raincoat 9 after another can be formed by the raincoat forming mechanism 3, as shown in Figure 10 However, since one side of the folded plastic film B is not closed, this side can only be used as the lower hem of the raincoat, so that one film can only form one raincoat after another in the same direction, and obviously this method will produce waste B0, which not only wastes materials but also does not maximize the utilization of the film. As shown in Figure 9 If the film uses the cylindrical plastic film A, one disposable raincoat 9 after another can be point cut on the cylindrical plastic film A by designing the shape of the forming slot 36 and reasonably arranging the heat sealing wire 35, as shown in Figure 7 Since both sides of the cylindrical plastic film A are closed, both sides can be used as the upper edge of the raincoat, so there is no waste, and the utilization of the film is maximized.
[0030] In order to realize the above-mentioned waste-free raincoat production, as shown in Figure 6 The forming slot 36 includes a first longitudinal slot 360 (the direction of all longitudinal slots refers to the vertical direction in Figure 7 up and down) and a first transverse slot 361 (the direction of all transverse slots refers to the horizontal direction in Figure 7The left and right directions in the figure include the horizontal and oblique directions), the second longitudinal groove 362, the second transverse groove 363, the third transverse groove 365, the third longitudinal groove 366, the fourth transverse groove 367 and the fourth longitudinal groove 368; wherein the first longitudinal groove 360 and the fourth longitudinal groove 368 are symmetrically arranged, the first transverse groove 361 and the fourth transverse groove 367 are symmetrically arranged, the second longitudinal groove 362 and the third longitudinal groove 366 are symmetrically arranged, the second transverse groove 363 and the third transverse groove 365 are symmetrically arranged; the second transverse groove 363 and the third transverse groove 365 are symmetrically arranged; A fifth longitudinal slot 364 is connected between the slots 365; the heat sealing wire 35 includes a first heating wire 351, a second heating wire 352, a third heating wire 353 and a fourth heating wire 354, wherein the first heating wire 351 is located outside the second longitudinal slot 362 and the second transverse slot 363, the second heating wire 352 is located inside the first transverse slot 361 and the second longitudinal slot 362, the third heating wire 353 is located outside the third transverse slot 365 and the third longitudinal slot 366, and the fourth heating wire 354 is located inside the third longitudinal slot 366 and the fourth transverse slot 367.
[0031] The forming principle of this waste-free raincoat is as follows: Figure 4 and Figure 5 As described above, the cross-sectional shape of the point-breaking knife 34 is the same as the shape of the forming groove 36, and the point-breaking knife 34 can completely enter all the grooves of the forming groove 36. The point-breaking knife 34 cuts the outer contour of a raincoat on the tube plastic film A in one action. When the tube plastic film A continues to move the distance of a raincoat, the point-breaking knife 34 moves again to cut the outer contour of another raincoat in the same direction on the tube plastic film A, and a raincoat contour in a different direction will be formed between these two raincoats in the same direction; since the first heating wire 351 is located outside the second longitudinal groove 362 and the second transverse groove 363, the first heating wire 351 heat-seals the lower end of the sleeve of the raincoat and the side of the main body, forming a Figure 7 Since the second heating wire 352 is located inside the first transverse groove 361 and the second longitudinal groove 362, the second heating wire 352 is heat-sealed to the lower end of the sleeve of another adjacent raincoat in a different direction and the side of the main body, forming a Figure 7 Since the third heating wire 353 is located outside the third transverse groove 365 and the third longitudinal groove 366, the third heating wire 353 is heat-sealed to the lower end of the sleeve of another adjacent raincoat in the same direction and the side of the main body, forming a Figure 7the third sealing line 95 shown in Fig. 5; since the fourth heating wire 354 is located inside the third longitudinal cutting groove 366 and the fourth transverse cutting groove 367, the fourth heating wire 354 heat-seals the lower end of the other sleeve and the other side of the main body of the raincoat of different orientation as mentioned above, forming the fourth sealing line 96 shown in Fig. 6; and the position without heat-sealing wire, due to no heat-sealing, can form the opening after point cutting, that is, forming the two sleeve openings 90 and the lower hem opening 91 of the raincoat 9, as shown in Fig. 7. Figure 7 Figure 9 The continuous point cutting and heat sealing can convert the plastic film A into raincoat completely without any waste, thus maximizing the utilization of the film and significantly reducing the production cost and improving the product competitiveness.
[0032] The heat-sealing pressure plate 37 is used to press the film against the heat-sealing wire 35 to ensure the full contact between the film and the heat-sealing wire 35, so the heat-sealing pressure plate 37 is provided at the position corresponding to each heat-sealing wire 35; however, in order to better realize point cutting, the corresponding heat-sealing pressure plate 37 is provided on both sides of the forming cutting groove 36, that is, the heat-sealing pressure plate 37 corresponds to all the heat-sealing wires 35 and all the two sides of the forming cutting groove 36, which has the advantage that the film can be pressed by the heat-sealing pressure plate 37 to make the point cutting knife 34 act more stably on the film, improve the point cutting stability, and improve the cutting surface effect.
[0033] In order to cut the notches on both sides of the film to form the collar opening 92 of the raincoat 9, as shown in Fig. 7, the first collar cutting groove 311 and the second collar cutting groove 312 are provided on the forming base 31, the first collar cutting groove 311 is located at the middle position between the first longitudinal cutting groove 360 and the fourth longitudinal cutting groove 368; the second collar cutting groove 312 is located at one side of the fifth longitudinal cutting groove 364. The first collar cutting knife 8 and the second collar cutting knife 7 are installed on the forming lifting base 30, the first collar cutting knife 8 can enter the first collar cutting groove 311, and the second collar cutting knife 7 can enter the second collar cutting groove 312. When the forming lifting base 30 is lowered, the first collar cutting knife 8 penetrates one side of the film and enters the first collar cutting groove 311, and the second collar cutting knife 7 penetrates the other side of the film and enters the second collar cutting groove 312, so that the collar opening 92 is cut on the adjacent raincoat 9 of different orientation, as shown in Fig. 7. Figure 6 Figure 7
[0034] As mentioned above, the forming cutting groove 36 can be arranged on the forming base 31 or the forming lifting base 30; the heat sealing wire 35 can also be arranged on the forming base 31 or the forming lifting base 30. However, the more reasonable arrangement is that the forming cutting groove 36 is arranged on the forming base 31, the heat sealing wire 35 is arranged on the forming base 31, the point cutting knife 34 is arranged on the forming lifting base 30, and the heat sealing pressing plate 37 is arranged on the forming lifting base 30. The forming lifting base 30 is lowered to drive the point cutting knife 34 into the forming cutting groove 36 and drive the heat sealing pressing plate 37 to press the film on the heat sealing wire 35. Regardless of the arrangement, it is within the protection scope of the utility model.
[0035] In order to make the heat sealing pressing plate 37 elastically act on the heat sealing wire 35 and make the film more fully and stably contact with the heat sealing wire 35, as shown in Figure 3 The heat sealing pressing plate 37 is connected to the pressing plate seat 38, and the pressing plate seat 38 is movably installed on the forming lifting base 30 through the connecting rod 39, the upper end of the connecting rod 39 is connected to the limiting piece 390 (the connecting rod 39 can be a screw rod, and the limiting piece 390 can be a nut), the limiting piece 390 is limited above the forming lifting base 30, and the connecting rod 39 is sleeved with the spring 380 for driving the pressing plate seat 38 to move downward. When working, the forming lifting base 30 drives the pressing plate seat 38 to move downward, so that the heat sealing pressing plate 37 connected to the bottom of the pressing plate seat 38 acts on the heat sealing wire 35. Since the connecting rod 39 can be raised and lowered on the forming lifting base 30, the pressing plate seat 38 moves upward, and the spring 380 gives the pressing plate seat 38 downward pressure, so that the heat sealing pressing plate 37 elastically acts on the heat sealing wire 35. The limiting piece 390 is limited above the forming lifting base 30 to prevent the connecting rod 39 from falling.
[0036] When the forming lifting base 30 is lowered, it can drive the point cutting knife 34 to move downward to point cut the film, but due to the reaction of the heat sealing pressing plate 37, when the heat sealing pressing plate 37 is pressed on the heat sealing wire 35, the forming lifting base 30 cannot be lowered too much, that is, the point cutting knife 34 cannot be lowered too much, which may affect the stability of the point cutting. In order to solve this problem, a point cutting power source (not shown in the figure) is installed on the forming lifting base 30, which can drive the point cutting knife 34 to move downward. When working, the forming lifting base 30 is lowered to press the heat sealing pressing plate 37 on the heat sealing wire 35, and the point cutting power source drives the point cutting knife 34 to move downward to point cut the film, which can improve the stability of the point cutting.
[0037] In order to make the film more fully and stably contact with the heat sealing wire 35, the heat sealing pressing plate 37 is a rubber plate. That is, the heat sealing pressing plate 37 itself has elasticity, which can make the heat sealing pressing plate 37 fully press on the heat sealing wire 35, so that the heat sealing effect of the film is better and more stable.
[0038] As shown in Figure 1As shown, the disposable raincoat machine further comprises a rear traction mechanism 2, and the raincoat forming mechanism 3 is located between the front traction mechanism 4 and the rear traction mechanism 2. The rear traction mechanism 2 is used to pull the film from the film roll, and the front traction mechanism 4 pulls the film to the raincoat forming mechanism 3. Since the front and rear ends are pulled by the front traction mechanism 4 and the rear traction mechanism 2 respectively, the raincoat forming mechanism 3 will not affect the film supply station in front and the film receiving station behind when it is forming, so that the forming work of the raincoat forming mechanism 3 can be carried out stably. It is worth mentioning here that the front traction mechanism 4 and the rear traction mechanism 2 both comprise traction roller groups and traction power sources.
[0039] Finally, it is worth mentioning that the disposable raincoat machine further comprises a film supply mechanism 1 and a forming and winding mechanism 5. The film supply mechanism 1 comprises film guide rollers, and the film roll enters the rear traction mechanism 2 through the guidance of the film guide rollers. The forming and winding mechanism 5 comprises winding rollers and winding power sources. Through the driving of the winding power sources, the winding rollers rotate to receive the completed film.
