Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figure 1-4 This utility model provides a fast-changing plastic film bag making and composite machine, including a supporting body 1;

[0038] The loading module 2 is located on the upper surface of the supporting body 1;

[0039] The feeding module 3 is located on the upper surface of the supporting body 1, and the feeding module 3 is located to the left of the loading module 2;

[0040] The hot pressing mechanism 4 is located on the upper surface of the supporting body 1. It includes a support frame 41 located on the upper surface of the supporting body 1 and the support frame 41 is located on the left side of the feeding module 3; two cylinders 42 are symmetrically arranged inside the support frame 41; and a heating plate 43 is located between the output ends of the two cylinders 42.

[0041] Cooling mechanism 5 is located on the upper surface of the supporting body 1, and the cooling mechanism 5 is located to the left of the hot pressing mechanism 4;

[0042] The cutting module 6 is located on the upper surface of the supporting body 1, and the cutting module 6 is located to the left of the cooling mechanism 5.

[0043] This embodiment presents a rapid-change plastic film bag making and composite machine of the present invention. The loading module 2 can place the plastic film roll, and then the feeding module 3 can feed the plastic film into the lower part of the hot pressing mechanism 4. The hot pressing mechanism 4 can then heat-seal the annular plastic film. When the plastic film moves to the lower part of the cooling mechanism 5, the cooling mechanism 5 can cool the heat-sealed part of the plastic film, so that the plastic film can be quickly formed. Then, the plastic film moves to the cutting module 6, and the cutting module 6 will cut the plastic film at the appropriate position between the two seals, thus completing the processing of the plastic bag.

[0044] More specifically, the loading module 2, the feeding module 3, and the cutting module 6 are all existing technologies, therefore this application will not describe them in detail.

[0045] Furthermore, such as Figure 2-3 As shown, the hot pressing mechanism 4 in the preferred embodiment of this utility model further includes a mounting sleeve 44 disposed on the upper surface of the support frame 41; a guide rod 45 disposed on the inner side of the mounting sleeve 44; two clearance holes 46 respectively opened on the left and right sides of the mounting sleeve 44; a bidirectional lead screw 47 rotatably disposed on the inner side of the mounting sleeve 44; a motor 48 disposed on the left side of the mounting sleeve 44, and the left end of the bidirectional lead screw 47 is disposed on the output end of the motor 48; two moving plates 49 respectively symmetrically and slidably disposed between the outer sides of the guide rod 45 and the bidirectional lead screw 47; two connecting rods 410 respectively symmetrically disposed on the outer sides of the two moving plates 49, and the two connecting rods 410 are respectively located on the inner side of the two clearance holes 46; and two hot pressing plates 411 respectively disposed on the other end face of the two connecting rods 410.

[0046] Furthermore, the outer side of the bidirectional lead screw 47 is threadedly connected to the inner side of the movable plate 49; the connecting rod 410 is a telescopic connecting rod.

[0047] Furthermore, the hot press plate 411 is a copper hot press plate, and the upper surface of the hot press plate 411 is in contact with the lower surface of the heating plate 43.

[0048] This embodiment provides several preferred embodiments of the hot pressing mechanism 4. The heating plate 43 heats the hot pressing plate 411, and then the cylinder 42 drives the heating plate 43 and the hot pressing plate 411 to move downwards, so that the lower surface of the hot pressing plate 411 contacts the upper surface of the plastic film, thereby sealing the plastic film. Then, the cylinder 42 drives the heating plate 43 and the hot pressing plate 411 to reset, so that the sealed plastic film can move normally. When it is necessary to process plastic bags of different specifications, the motor 48 drives the bidirectional lead screw 47 to rotate. The rotating bidirectional lead screw 47 drives the two moving plates 49 located outside the guide rod 45 to move. The moving plates 49 drive the hot pressing plate 411 to move through the connecting rod 410, thereby adjusting the distance between the two hot pressing plates 411, so as to process plastic bags of different specifications and sizes.

[0049] Furthermore, such as Figure 4 As shown, the cooling mechanism 5 in the preferred embodiment of this utility model includes a mounting frame 51 disposed on the upper surface of the supporting body 1; a cooler 52 disposed on the upper surface of the mounting frame 51; a telescopic tube 53 disposed in connection with the air outlet of the cooler 52; a T-shaped block 54 slidably disposed on the inner side of the mounting frame 51; a blower sleeve 55 disposed on the lower surface of the T-shaped block 54; and a linkage rod 56 disposed between the outer side of the blower sleeve 55 and the connecting rod 410.

[0050] Furthermore, a T-shaped groove is formed on the inner side of the mounting bracket 51, and a T-shaped block 54 is slidably disposed on the inner side of the T-shaped groove.

[0051] This embodiment provides several preferred embodiments of the cooling mechanism 5. Through the telescopic tube 53, cold air generated by the air cooler 52 can be sent into the blower sleeve 55. The blower sleeve 55 then evenly blows out the cold air, thereby cooling the sealed plastic film and increasing the forming speed of the plastic film. Since the blower sleeve 55 is slidably mounted inside the mounting frame 51 via the T-shaped block 54, the adjustability of the blower sleeve 55 is ensured. Therefore, when the telescopic rod 410 adjusts the position of the hot press plate 411, the linkage rod 56 will drive the blower sleeve 55 to move. This allows adjustment of the distance between the blower sleeve 55 and the nearest hot press plate 411 on the right side. This not only does not affect the hot press plate 411's sealing of the plastic film but also cools and forms the plastic film immediately, preventing damage to the sealed plastic film during movement and thus improving the processing quality of the plastic bag.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
