Description

Heat sealing knife device

Technical Field

The utility model relates to an encapsulation equipment especially relates to a sealing knife device.

Background

Before shipping, a bottle-packed product is packaged in a heat-shrinkable bag 11. A flat heat seal knife then cuts a flat heat seal edge as shown in fig. 1. Then, the heat-shrinkable bag 11 is heated by hot air blowing to shrink, and the packaging bottle 12 is tightly wrapped. Since the heat-seal edge is flat and the hot air of the hot blast contacts the heat-shrinkable bag 11, the temperature distribution in the space is uncontrollable, resulting in uncontrollable shrinkage directions at the corners of both ends of the heat-seal edge after shrinkage.

When the contraction angle is tangent to the bottom of the packaging bottle 12 and the angle part is raised, as shown in fig. 2, the packaging bottle can stand upright on a subsequent sales shelf, and the packaging bottle is classified as a good product when being shipped out of a factory. In contrast, when the contraction angle is tangent to the body of the packaging bottle 12 and the corner is turned down, as shown in fig. 3, the packaging bottle cannot stand upright on a subsequent sales shelf and is classified as a defective product when the packaging bottle leaves the factory. The inferior products are treated by removing the heat-shrinkable bag 11 after heat sealing and then re-packaging until the products become good products. On a miniaturized production line, the defective rate is as high as more than three.

A spring is sleeved between the upper end part of the slide rail and the slide block; the upper end of the spring is fixedly connected with the upper end part of the slide rail, and the lower end of the spring is fixedly connected with the slide block.

The tool holders are symmetrically arranged on the edges of two sides of the tool rest.

The tool post is provided with a positioning groove, one end of the positioning groove is close to the middle part of the arc-shaped concave inner part of the tool pad, and the other end of the positioning groove extends towards the edge of the tool post.

The utility model discloses in a sealing knife device, its advantage lies in, can cut the heat-seal limit into the arc, and the arc direction shifts up to the bottle lid direction from the bottle bottom, and the angle that tightens up of angle of contraction when making hot-blast shrink is the angle that rises. Thereby the yield of the product after packaging is improved, and the resource waste caused by manual unpacking and reworking is avoided. Through the resilience resetting of the spring, the worker only needs to apply the heat-sealing cutting operation of pressing down, the resetting of hands is not needed, and the working efficiency is improved. Both sides are established separately to the handle of a knife, and the atress is even when guaranteeing to push down, avoids cutting incompleteness. The setting of constant head tank can improve the counterpoint efficiency when the packing bottle is put into, makes the encapsulation effect of every product keep unanimous basically.

Detailed Description

As shown in fig. 4, the heat sealing knife device of the present invention includes a knife holder 25 and a knife rest 21 stacked from top to bottom.

The upper end surface of the knife platform 21 is fixedly provided with a knife pad 22, and four corners of the knife platform 21 are respectively provided with a slide rail 23 which extends upwards and vertically. Four corners of the tool rest 25 are respectively provided with a sliding block 29 corresponding to the sliding rail 23 one by one. The middle part of the knife rest 25 is provided with an arc-shaped heat sealing knife 28, and the middle part and two ends of the heat sealing knife 28 are respectively fixedly connected with the lower end face of the knife rest 25. The vertical position and shape of the shim 22 is adapted to the heat seal knife 28. The edge of the tool holder 25 extends outwardly to provide a shank 27. A spring 26 is sleeved between the upper end part of the slide rail 23 and the slide block 29. The upper end of the spring 26 is fixedly connected with the upper end part of the slide rail 23, and the lower end is fixedly connected with the slide block 29. The tool holders 27 are symmetrically arranged on the edges of two sides of the tool holder 25. The knife rest 21 is provided with a positioning groove 24, one end of the positioning groove 24 is close to the middle part of the arc-shaped concave of the knife pad 22, and the other end extends towards the edge of the knife rest 21.

The utility model discloses in a sealing knife device working process as follows: first, in the initial state shown in fig. 4, the heat seal knife 28 is heated to the operating temperature by energization. The manner of electrically heating the heat seal knife 28 and the corresponding circuit configuration are well known in the art. The packaging bottle 12 is placed into the heat shrinkable bag 11 and then placed on the positioning groove 24. The bottom of the packaging bottle 12 is close to the knife pad 22, the opening direction of the heat-shrinkable bag 11 is far away from the bottle cap of the packaging bottle 12, and the excess material near the heat-shrinkable bag 11 is placed on the other side across the knife pad 22, as shown in fig. 5. The handle 27 is held by both hands while being pressed down with force, so that the heat-sealing knife 28 is fully contacted with the shim 22. The hot knife 28 at high temperature cuts off the excess of the heat-shrinkable bag 11 as shown in fig. 6. The spring 26 will return the blade holder 25 to move up when the downward pressure is released. The heat-sealed packaging bottle 12 and the cut materials of the heat-shrinkable bag 11 are taken away, and the heat-sealing operation of the next new packaging bottle 12 can be continued. The heat-sealing edge at the bottom of the packaging bottle 12 is shown in fig. 7, when the packaging bottle is subsequently shrunk by hot air, the heat-sealing edge is in a specific shape, so that the packaging bottle inevitably shrinks from a position close to the bottle body, and the good product effect of rising shrinkage angle is ensured, as shown in fig. 2.

Utilize the utility model discloses in a heat-seal knife device carries out heat-seal packing, tests through the production line of many batches up to ten thousand, does not reappear like the inferior goods condition shown in figure 3.

Various other modifications and changes can be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes should fall within the scope of the claims.
