Description

Technical Field

[0001] This utility model relates to the field of packaging bag sealing technology, and in particular to a packaging bag sealing and trimming machine. Background Technology

[0002] A sealing machine is a machine that seals containers filled with packaging materials. After a product is placed into a packaging container, it needs to be sealed to preserve the product, maintain its quality, and prevent product loss. This operation is done on a sealing machine. There are many types of sealing machines, and different sealing machines are required for different packaging containers.

[0003] Chinese patent CN213893052U discloses a sealing device for food packaging bags. In use, the horizontal plate 32 is pressed directly, at which time the second spring 34 is compressed. The elastic force of the second spring 34 acts downward on the pressing plate 21, causing the pressing plate 21 to be pressed down as well. When the elastic coefficient of the second spring 34 is higher than that of the first spring 24, the pressing plate 21 will first press the upper heating element onto the packaging bag. After holding it for a certain period of time, the pressing will continue to press down, fully pressing down the cutter 31, so that the cutter 31 cuts off the excess packaging bag. Finally, the pressing plate 21, the cutter 31, etc. will automatically return to their previous positions under the elastic force of the first spring 24 and the second spring 34. However, when cutting the edge of the packaging bag, it is not possible to ensure that the heating element and the packaging bag maintain a suitable pressure. Excessive pressure between the heating element and the packaging bag can easily damage the packaging bag. To solve the above problems, a packaging bag sealing and cutting machine is provided. Utility Model Content

[0004] In order to solve the problems mentioned in the background art, the present invention provides a packaging bag sealing and edge cutting machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A packaging bag sealing and cutting machine includes a fixed base, a worktable at the top of the fixed base, a connecting frame on the fixed base, a cylinder at the top of the connecting frame, and a cutter at the bottom of the cylinder output shaft.

[0007] A fixed plate is slidably connected to the cylinder output shaft, and a first telescopic rod is fixedly connected to the fixed plate. A hot pressure plate is provided at the bottom end of the first telescopic rod.

[0008] Preferably, the top of the workbench is provided with a cutting groove corresponding to the cutter.

[0009] Preferably, a first spring is sleeved on the cylinder output shaft, and the movable end of the first spring is fixedly connected to the top of the fixed plate.

[0010] Preferably, a second spring is sleeved on the first telescopic rod, and the movable end of the second spring is fixedly connected to the top of the hot press plate.

[0012] Preferably, the fixed plate is provided with a connecting plate, the bottom end of the connecting plate is provided with a second telescopic rod, and the movable end of the second telescopic rod is provided with a pressure plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The downward movement of the fixed plate can drive the hot press plate to move downward and press onto the packaging bag for heat sealing. When the fixed plate contacts the limit block, the fixed plate is fixed. When the cylinder continues to extend to cut the edge, the pressure between the hot press plate and the packaging bag remains unchanged. The hot press plate always maintains appropriate pressure and contact with the packaging bag, resulting in a good heat sealing effect.

[0015] 2. Between the contact between the hot press plate and the packaging bag, the pressure plate contacts the packaging bag, and the connecting plate continues to move downward. The restoring force of the third spring can press and fix the packaging bag. At this time, the hot press plate contacts the packaging bag, the heat sealing effect is good, and wrinkles are not easy to occur.

[0016] In summary, this utility model overcomes the shortcomings of the prior art, has a reasonable design, and can remove excess parts of the packaging bag while heat-sealing it, and maintain the pressure between the hot press plate and the packaging bag while cutting the edge. It has high social use value and application prospects. Attached Figure Description

[0022] Example 1

[0023] Reference Figure 1-2 A packaging bag sealing and trimming machine includes a fixed base 1, a worktable 14 at the top of the fixed base 1, a connecting frame 11 on the fixed base 1, a cylinder 12 at the top of the connecting frame 11, a cutter 13 at the bottom of the output shaft of the cylinder 12, a cutting groove 141 corresponding to the cutter 13 at the top of the worktable 14, a fixed plate 2 slidably connected to the output shaft of the cylinder 12, and a first spring 121 sleeved on the output shaft of the cylinder 12, with the movable end of the first spring 121 fixedly connected to the top of the fixed plate 2.

[0024] A first telescopic rod 211 is fixedly connected to a fixed plate 2. A hot press plate 22 is provided at the bottom of the first telescopic rod 211. A second spring 212 is sleeved on the first telescopic rod 211. The movable end of the second spring 212 is fixedly connected to the top of the hot press plate 22. When the packaging bag is placed on the workbench 14, the starting cylinder 12 can drive the fixed plate 2 to move downward. The downward movement of the fixed plate 2 can drive the hot press plate 22 to move downward and press it onto the packaging bag for heat sealing. When the starting cylinder 12 continues to move downward, the fixed plate 2 is slidably connected to the output shaft of the cylinder 12 and will not continue to move downward. At the same time, it drives the cutter 13 to move downward, which, together with the cutting groove 141, can cut the edges of the packaging bag.

[0025] Furthermore, a second cylinder 142 is provided at the top of the workbench 14, and a limit block 1421 is provided at the output end of the second cylinder 142. When the cylinder 12 extends, the hot press plate 22 presses onto the workbench 14 with a certain pressure, and the fixing plate 2 contacts the limit block 1421. At this time, the fixing plate 2 is fixed. When the cylinder 12 continues to extend and cut the edge, the pressure between the hot press plate 22 and the packaging bag remains unchanged. The hot press plate 22 always maintains a suitable pressure and contacts the packaging bag, resulting in a good heat sealing effect.

[0026] Furthermore, the fixed plate 2 is provided with a connecting plate 21, the bottom end of the connecting plate 21 is provided with a second telescopic rod 23, the movable end of the second telescopic rod 23 is provided with a pressure plate 24, the pressure plate 24 is used to fix the packaging bag placed on the workbench, and a third spring 231 is sleeved on the second telescopic rod 23, the movable end of the third spring 231 is fixedly connected to the pressure plate 24.

[0027] Working principle: When the packaging bag is placed on the workbench 14, the cylinder 12 is activated, which drives the fixed plate 2 to move downward. The downward movement of the fixed plate 2 drives the hot press plate 22 to move downward and press it onto the packaging bag for heat sealing. The fixed plate 2 contacts the limit block 1421, at which point the fixed plate 2 is fixed. When the cylinder 12 continues to extend to cut the edge, the pressure between the hot press plate 22 and the packaging bag remains unchanged. The hot press plate 22 always maintains appropriate pressure in contact with the packaging bag, resulting in a good heat sealing effect.

[0028] Between the contact between the hot press plate 22 and the packaging bag, the pressure plate 24 contacts the packaging bag, and the connecting plate 21 continues to move downward. The packaging bag can be pressed and fixed by the restoring force of the third spring 231. At this time, the hot press plate 22 contacts the packaging bag, the heat sealing effect is good, and wrinkles are not easy to occur.
