Description

Technical Field

[0001] The utility model relates to the technical field of plastic film packaging bag sealing equipment, in particular to a film sealing machine and an anti-skew edge mechanism thereof. Background Art

[0002] The film sealing machine is composed of a frame, a speed reduction transmission mechanism, a sealing mechanism, a conveying device, and an electrical and electronic control system. It uses constant temperature control to seal plastic film packaging bags. In production, it is used in conjunction with a packaging bag conveyor belt. It is usually used for continuous production of the same model of products, and its sealing length is not limited.

[0003] However, when used in the laboratory, a plastic film sealing machine may need to seal plastic packaging bags of different sizes. At this time, it is necessary to frequently adjust the position of the bag conveyor belt so that the sealed part of the packaging bag can be fed into the film sealing machine; or even if the same size of plastic packaging bags are sealed, when the volume of the products contained in the plastic packaging bags is different, it is also necessary to adjust the position of the bag conveyor belt. The conveyor is relatively bulky and very inconvenient to adjust. In addition, the width of the conveyor belt of the existing plastic film sealing machine is fixed, and the width of the conveyor belt mechanism cannot be adjusted, which greatly limits its scope of application. Therefore, when operating the sealing in the laboratory, the experimenter often directly holds the packaging bag to seal, and the sealing edge often appears crooked. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a film sealing machine and its anti-skew edge mechanism, which aims to improve the situation of sealing skew edge during use through a simple anti-skew edge mechanism. It has a simple structure and is easy to adjust, and can be suitable for sealing operations of packaging bags of different sizes and thicknesses.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A film sealing machine comprises a sealing machine body and an anti-distortion mechanism.

[0007] Its anti-distortion mechanism includes a horizontal sealing platform, with sliding seats at both ends of the sealing platform, and vertical plates on the sliding seats. Two supporting columns are arranged on the bottom of the sealing platform close to the sealing machine body, and the supporting columns are arranged on the fixed seat through sliding sleeves. The two supporting columns are provided with scale lines with consistent heights. The sliding seat and the sliding sleeve are both provided with locking bolts. The sealing platform is a smooth flat plate, and the height is adjusted by adjusting the fixed position of the supporting column in the sliding sleeve to adapt to packaging bags of different thicknesses. When the packaging bags are placed on the sealing platform, their sealing parts correspond to the sealing mechanism, and the vertical plates adjust their positions through the sliding seats to limit the packaging bags to adapt to packaging bags of different lengths. When sealing, the operator only needs to hold the packaging bag with his hand and gently push the packaging bag with the sealing machine to avoid the situation where the packaging bag is easily distorted when sealed by hand, and it can be suitable for packaging bags of different sizes.

[0008] Further preferably, the sealing platform includes a frame-shaped frame, in which a plurality of rollers are arranged along the moving direction of the packaging bag, and each roller is provided with a plurality of rollers. The rollers rotate flexibly on the rollers, thereby converting the sliding friction between the packaging bag and the sealing platform into rolling friction, which can effectively reduce the friction force and make it easier to gently push the packaging bag along with the sealing machine.

[0009] The rollers are evenly distributed on the roller shaft, and the use of the rollers can help the packaging bag maintain a stable translation direction.

[0010] A column of a certain length is arranged on the slide seat, and the vertical plate is fixed on the column.

[0011] The support column is arranged on one side of the sealing platform close to the sealing machine body.

[0012] The fixing seat is arranged at the lower part of the sealing machine body.

[0013] Diagonal support rods are arranged between the two ends of the sealing platform and the support columns.

[0014] The utility model has the characteristics of simple structure, small volume, light weight, convenient adjustment and use, and strong practicality, and is worthy of wide promotion and application. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings of the specification of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Embodiment 1

[0020] See also Figure 1 The utility model provides an embodiment: a film sealing machine, comprising a sealing machine body 1 and an anti-skew edge mechanism 2 arranged on the sealing machine body 1.

[0021] The anti-skew edge mechanism 2 includes a horizontal sealing platform 21, with slides 22 provided at both ends of the sealing platform 21, with vertical plates 23 provided on the slides 22, and with columns 28 of a certain length provided on the slides 22, and the vertical plates 23 are fixed on the side of the columns 28. Two support columns 24 are provided at the bottom of the sealing platform 21 close to the sealing machine body 1, and diagonal braces 29 are provided between the two ends of the sealing platform 21 and the corresponding support columns 24. The support columns 24 are arranged on the fixed seats 26 through the sliding sleeves 25. In this embodiment, the fixed seats 26 are arranged at the lower part of the sealing machine body 1. The two support columns 24 are provided with scale lines 241 with the same height, so that when the support columns 24 on both sides are adjusted, their heights are kept consistent, so that the sealing platform 21 remains horizontal and adapted to the sealing structure on the sealing machine body 1.

[0022] The slide 22 and the sleeve 25 are both provided with dovetail locking bolts 27, which are threadedly connected to the slide 22 and the sleeve 25 and extend into the slide 22 and the sleeve 25 to press against the sealing platform 21 and the support column 24 to lock them. In this embodiment, the sealing platform 2 is a smooth flat plate, and the height is adjusted by adjusting the fixed position of the support column 24 in the sleeve 25 to adapt to the packaging bags of different thicknesses placed on the sealing platform 21, and the sealing part thereof corresponds to the sealing mechanism on the sealing machine body 1. The vertical plate 23 is adjusted between the slide 22 and the sealing machine body 1 to adapt to packaging bags of different lengths, and the packaging bags are limited and prevented from deflection. When sealing, the operator only needs to hold the packaging bag by hand and gently push the packaging bag forward with the sealing machine to avoid the situation that the packaging bag is easily distorted when sealed by hand, and it can be applied to packaging bags of different sizes.

[0023] Embodiment 2

[0024] See also Figure 2 and 3The difference between this embodiment and the first embodiment is that: the sealing platform 21 includes a frame-shaped frame 212, and a plurality of rollers 213 are arranged in the frame 212 along the moving direction of the packaging bag. A plurality of rollers 211 are passed through each roller 213, and the rollers 211 are evenly distributed on the rollers 213. The rollers 211 flexibly rotate on the rollers 213, and the sliding friction between the packaging bag and the sealing platform 21 is converted into rolling friction, which can effectively reduce the friction force, and is more convenient to gently push the packaging bag along with the sealing machine, and the rollers 211 help the packaging bag to maintain a stable translation direction.

[0025] In this embodiment, the slide seat 22 is sleeved on the frames at both ends of the frame body 212 and slides along the frames, and the frames at both ends of the frame body 212 are provided with corresponding scale lines to facilitate accurate translation adjustment of the vertical plate 23.

[0026] Working principle: When in use, the height of the sealing platform 21 is adjusted by adjusting the fixed height in the sliding sleeve 25 through the support column 24, so that when packaging bags of different thicknesses are placed on the sealing platform 21, the part of the packaging bag to be sealed corresponds to the height of the sealing mechanism on the sealing machine body 1. By adjusting the fixed position of the slide 22, the position of the vertical plate 23 is adjusted to adapt to packaging bags of different lengths, so that the vertical plate 23 limits the packaging bag on one side. The packaging bag is usually square, and the packaging bag can be prevented from being skewed by the limitation of the vertical plate 23. When sealing, the operator only needs to hold the packaging bag with his hand and gently push the packaging bag forward with the sealing machine.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
