Description

Technical Field

[0001] This utility model relates to the field of heat shrink packaging technology, specifically a multi-specification adaptive heat shrink packaging device. Background Technology

[0002] As is well known, in the heat shrink packaging industry, heat shrink packaging machines are important equipment used to shrink and tightly wrap items by heating packaging film. However, in practical applications, in order to adapt to different sizes and types of packaging needs, it is often necessary to change different film rollers to load packaging films of corresponding specifications. Traditional equipment usually requires operators to manually load, unload, and adjust the position of the film rollers. This means that operators must accurately align the two ends of the film rollers and ensure their stable installation. This is not only time-consuming and labor-intensive, but also prone to errors due to human factors, affecting the packaging effect. Since the equipment needs to be readjusted every time the film roller is changed, especially when different specifications of packaging film need to be changed frequently, this adjustment process greatly limits production efficiency. During manual operation, improper operation may cause damage to mechanical parts or even safety accidents, posing a potential threat to the safety of operators. Therefore, it is necessary to propose a solution to this technical problem. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-4This utility model relates to a multi-specification adaptive heat shrink packaging device, comprising a heat shrink packaging machine body 1. A film feeding mechanism is provided at the top of the heat shrink packaging machine body 1. The film feeding mechanism includes a mounting plate 2, an opening 3, and a film roller 4. The mounting plate 2 is mounted at the top of the heat shrink packaging machine body 1. The opening 3 is located at the top of the heat shrink packaging machine body 1. A telescopic mechanism 5 and an adjusting box 13 are provided at the top of the mounting plate 2. The output end of the telescopic mechanism 5 is connected to the adjusting box 13. An adjusting hole is provided on the adjusting box 13. A bidirectional lead screw 6 is provided on the adjusting hole. Adjusting blocks 7 are provided at both ends of the bidirectional lead screw 6. Threaded holes are provided on the adjusting blocks 7. The bidirectional lead screw 6 passes through the threaded holes. A bearing seat 8 is provided between the segment 7 and one end of the film roller 4. An adjusting gear 9 is provided on the bidirectional lead screw 6. The adjusting gear 9 is located inside the adjusting box 13. A drive motor 10 is provided at one end of the adjusting box 13. The output end of the drive motor 10 extends into the adjusting box 13 and is provided with a drive gear 11. The drive gear 11 meshes with the adjusting gear 9. A guide mechanism is provided between the mounting plate 2 and the two adjusting blocks 7. In this embodiment, when using the heat shrink packaging machine body 1, one end of the film roller 4 containing the protective film is abutted against the bearing seat 8 of one adjusting block 7, and the other end of the film roller 4 is aligned with the bearing seat 8 of the other adjusting block 7. Then, the drive gear is rotated by controlling the output end of the drive motor 10. 11. The drive gear 11 meshes with the adjusting gear 9, enabling the adjusting gear 9 to drive the bidirectional lead screw 6 to rotate. The bidirectional lead screw 6 passes through the threaded holes of the two adjusting blocks 7, allowing the two adjusting blocks 7 to move in opposite directions and move closer together. Through the guide mechanism, the adjusting blocks 7 can slide stably linearly on the mounting plate 2, causing the bearing seat 8 of the other adjusting block 7 to engage with one end of the film roller 4, thus automatically clamping and assembling the film roller 4. By controlling the output end of the telescopic mechanism 5 to linearly move the adjusting box 13 on the mounting plate 2, the position can be flexibly adjusted according to the size and type of packaging film assembled on the film roller 4, facilitating the alignment of the film roller 4 with the items to be packaged on the heat shrink packaging machine body 1. The output of the drive motor 10 rotates in reverse, causing the two adjusting blocks 7 to move away from each other, thus quickly replacing the film roller 4. This allows personnel to easily change the packaging film to the appropriate size and type according to production needs, making it faster and eliminating the need for manual assembly or disassembly of the film roller 4. Furthermore, by controlling the telescopic mechanism 5, the position can be adjusted according to the type of packaging film on the film roller 4, facilitating alignment with the items. The drive motor 10 and telescopic mechanism 5 in this structure can be automatically controlled according to existing technology, thereby achieving adaptive position adjustment. The packaging film enters the interior of the heat shrink packaging machine body 1 through the opening 3 for heat shrink packaging. The heat shrink packaging machine body 1 is a common heat shrink packaging device in daily life.The internal workings and principles are based on existing technology and will not be described in detail here.

[0024] In this solution, the guiding mechanism includes a guide groove and a guide bar 12. The guide bar 12 is installed on the top of the mounting plate 2, and the guide groove is opened at the bottom of the adjusting block 7. The guide bar 12 passes through the guide groove. By passing through the guide groove opened on the two adjusting blocks 7, the adjusting blocks 7 can slide more stably in a straight line on the mounting plate 2.

[0025] In this solution, two guide mechanisms are provided and symmetrically arranged. The stability of the linear movement of the adjusting block 7 can be further improved by using two symmetrically arranged guide mechanisms.

[0026] In this design, both the guide groove and the guide bar 12 are T-shaped. The T-shaped guide groove and guide bar 12 can improve the stability of the guide bar 12 in the guide groove and reduce shaking.

[0027] In this scheme, the telescopic mechanism 5 is an electric telescopic rod, which has the characteristics of high movement accuracy and good stability, thereby improving the movement accuracy of the control and adjustment box 13.

[0028] In this design, a bearing is provided between the output end of the drive motor 10 and the inner wall of the regulating box 13, which can improve the rotational stability of the output end of the drive motor 10.

[0029] In this scheme, the drive motor 10 is a servo motor, which has the characteristic of high rotational accuracy, thereby improving the rotational accuracy of the bidirectional lead screw 6.

[0030] In this solution, the mounting plate 2 is made of heat-insulating material. The heat-insulating material can reduce the heat conduction to the drive motor 10 and the telescopic mechanism 5, ensuring the normal operation of the device and preventing it from being affected by the high temperature of the heat shrink packaging machine body 1. The heat-insulating material is a common heat-insulating material in the prior art, such as aluminum alloy.

[0031] 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.
