Abstract
Description

[0058] The traction unit is located between the longitudinal cutting unit and the transverse cutting unit, and is used to drive the packaging bag through the flattening unit, longitudinal cutting unit and transverse cutting unit in sequence.
[0059] By adopting the above technical solution and by the mutual cooperation of the various units of the cutting mechanism, the packaging bag can be cut efficiently and accurately.
[0060] Example 2:
[0061] This embodiment provides a surgical knife packaging machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0062] Furthermore, the horizontal cutting unit includes:
[0063] The cutting seat 3 is fixedly mounted on the machine body 1 and has a U-shaped structure including a base and vertical plates installed on both sides of the base;
[0064] The upper cutting plate 4 is slidably mounted between the two vertical plates 1;
[0065] The lower cutting plate 5 is fixedly mounted on the upper end of the base;
[0066] Among them, the upper cutting plate 4 and the lower cutting plate 5 are respectively fixed with an upper transverse cutter 6 and a lower transverse cutter 7, and a transverse cutting area is formed between the upper transverse cutter 6 and the lower transverse cutter 7;
[0067] Among them, a support plate 8 for supporting the packaging bag is fixedly installed above the lower cutting plate 5, and the support plate 8 is located upstream of the upper transverse cutter 6 and the lower transverse cutter 7.
[0068] In the above technical solution, both ends of the upper cutting plate extend out of the vertical plates and are connected and fixed with push rods for driving the upper cutting plate to move up and down. The push rods are connected to the external motor through a cam transmission to ensure its cutting stability.
[0069] By adopting the above technical solution, the vertical plate 1 is set to provide auxiliary support and limit for the upper cutting plate to prevent its cutting deviation. Combined with the upper and lower cutting knives, the packaging bag can be effectively cut horizontally to avoid sticking during cutting.
[0070] Example 3:
[0071] This embodiment provides a surgical knife packaging machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0072] Furthermore, the longitudinal cutting unit includes:
[0073] The second support plate 9 is located above the body 1 and is fixedly connected to the base via a support arm;
[0074] The strip block 10 is fixedly installed horizontally above the support plate 2 9;
[0075] The fixing block 11 is fixedly mounted on the middle portion of the upper end of the strip block 10, and an end of the fixing block 11 facing the transverse cutting unit is provided with an outwardly extending extension portion;
[0076] longitudinal cutter 12;

[0088] By adopting the above technical solution, a V-shaped guide area can be formed between the end of the upper splint and the lower splint. The packaging bag sent out through the upper film hot pressing station first enters the guide area, and then passes through between the upper and lower splints to assist in flattening the packaging bag.
[0089] Example 5:
[0090] This embodiment provides a surgical knife packaging machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0091] Furthermore, the traction unit further comprises:

Slide plates are slidably installed on the opposite sides of the vertical plates 18, and the two ends of the pressure roller 16 are rotatably connected to the two slide plates respectively.
[0095] By adopting the above technical solution, the traction unit assists in traction of the packaging bags, and the pressure roller adjacent to the longitudinal cutter enables the longitudinally cut packaging bags to quickly enter the packaging bag traction area and be pulled, and is less likely to deviate, thereby avoiding interference with the downstream transverse cutting area. The sliding roller can adjust the gap in the traction area to adapt to packaging bags of different specifications.

[0102] Furthermore, a support plate 3 21 for supporting the vertical plate 2 18 is fixedly connected between the vertical plate 2 18 and the vertical plate 1 .
[0103] By adopting the above technical solution, when the transverse cutting unit moves, the support plate three can simultaneously drive the traction unit to move, without having to readjust the position of the traction unit separately, thus facilitating operation.
[0104] Example 8:
[0105] This embodiment provides a surgical knife packaging machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0110] By adopting the above technical solution, a cursor is printed on the edge of the upper or lower film during production. The photoelectric sensor detects the cursor of the upper film and determines the distance that each section of the packaging bag on the equipment needs to be dragged through the cursor, so that the blade can load the material accurately and the subsequent horizontal cutting can be done accurately.
[0111] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
