Description

Technical Field

[0001] This utility model relates to the technical field of heat shrink film devices, and in particular to a heat shrink film device for temperature-controlled hot air sealing of bottle caps. Background Technology

[0002] With the rapid development of society, there is now a call to limit excessive packaging of goods in order to promote environmental protection. Some food bottles may no longer need an outer sealed box, while others will require an additional PVC film to be sealed between the bottle body and the cap after the cap is sealed to achieve a tight seal.

[0003] Existing packaging equipment uses steam heating to heat-shrink the PVC film on the bottle. However, steam heating often leaves water vapor residue between the bottle and the PVC film, which can lead to quality risks during product storage. Utility Model Content

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0021] Please refer to the following: Figures 1 to 3 As shown, Figure 1 A schematic diagram of the overall structure of a heat shrink film device 100 for temperature-controlled hot air sealing of bottle caps; Figure 2 A schematic diagram of the heat shrink film device 100 for temperature-controlled hot air sealing of bottle caps with the housing 40 in a split state. Figure 3 This is a schematic diagram of the structure of the heat shrink film device 100 for sealing bottle caps with temperature-controlled hot air, in which the base 10 is in a split state.

[0022] This utility model provides the following technical solution: a heat shrink film device 100 for temperature-controlled hot air sealing of bottle caps, including a base 10, a control panel 20, a conveying assembly 30, a cover 40, a fan assembly 50, and a heating element 60; the conveying assembly 30 is fixedly disposed on the top of the base 10, the cover 40 is fixedly disposed on the top of the base 10 and covers the middle part of the conveying assembly 30, and the front end of the cover 40 is provided with an inlet 401 and the rear end is provided with an outlet 402, the fan assembly 50 is fixedly disposed on the top of the cover 40 and partially extends into the interior of the cover 40, the heating element 60 is fixedly disposed inside the cover 40 and is located at the lower end of the fan assembly 50, and the control panel 20 is fixedly disposed on the side of the base 10 and is electrically connected to the conveying assembly 30, the fan assembly 50, and the heating element 60 respectively.

[0023] Due to the promotion of restrictions on excessive packaging of goods, some bottles containing food can choose not to have an outer sealed box. However, some bottles need to be sealed with a PVC film between the bottle body and the cap after the cap is sealed to achieve a sealing effect.

[0024] This embodiment provides a heat-shrink film device 100 for temperature-controlled hot air sealing of bottle caps. When heat-shrink sealing of PVC film on bottles is required, the bottles with PVC film on them can be placed sequentially on the conveying assembly 30. The conveying assembly 30 then sequentially conveys the bottles with PVC film on them into the housing 40 from the inlet 401. As the bottles with PVC film on them enter the housing 40, they pass sequentially through the lower end of the heating element 60 to receive the heat-shrink sealing film. The heating element 60 at the lower end of the fan assembly 50 is responsible for heating, while the fan assembly 50 is responsible for fanning. The air blown by the fan assembly 50 is heated by the lower heating element 60 and then blown onto the bottles, causing the PVC film on the bottles to shrink due to the hot air, thus completing the heat-shrink sealing of the PVC film on the bottles. The bottles with PVC film sealed inside the housing 40 are then sequentially conveyed out of the discharge port 402 by the conveying assembly 30. The control panel 20 is used for the user to control the operation of the conveying assembly 30, the fan assembly 50, and the heating element 60. In this invention, bottles covered with PVC film are sequentially conveyed into the housing 40 by the conveying component 30 to receive the hot air generated by the fan component 50 and the heating element 60 for heat shrink sealing, which has the advantages of being convenient and efficient.

[0025] In some embodiments, a temperature sensor 70 is fixedly disposed inside the housing 40, the temperature sensor 70 is disposed close to the heating element 60, and the control panel 20 is electrically connected to the temperature sensor 70.

[0026] In practice: Temperature sensor 70 is used to sense the temperature generated by the heating element 60. Temperature sensor 70 transmits the sensed temperature value of heating element 60 to control panel 20. Control panel 20 then controls the heating power of heating element 60 based on the temperature value sensed by temperature sensor 70, so as to adjust the heating temperature of heating element 60 within the preset standard temperature value. This facilitates the temperature control of heating element 60 to the standard temperature value to match the appropriate temperature for heat shrink sealing of PVC film on bottle.

[0027] In some embodiments, the conveying assembly 30 includes a drive motor 301, a drive shaft 302, a driven shaft 303, and a conveyor belt 304; the drive motor 301 is fixedly disposed on the side of the base 10, the drive shaft 302 is rotatably disposed on the top front end of the base 10, the driven shaft 303 is rotatably disposed on the top rear end of the base 10, the conveyor belt 304 is wound around and connected to the drive shaft 302 and the driven shaft 303, and the output end of the drive motor 301 is connected to one end of the drive shaft 302.

[0028] In specific implementation: When the conveying component 30 conveys the PVC-film-covered bottles into the housing 40 for heat shrink sealing, the PVC-film-covered bottles can be placed sequentially on the conveyor belt 304. The drive motor 301 drives the drive shaft 302 to rotate. When the drive shaft 302 rotates, it drives the conveyor belt 304 to rotate cyclically at one end. The driven shaft 303 supports the other end of the conveyor belt 304. Thus, when the conveyor belt 304 rotates cyclically, it conveys the PVC-film-covered bottles into the housing 40 for heat shrink sealing, so that the conveying component 30 can effectively convey the bottles.

[0029] In some embodiments, a plurality of grooves 3041 are arranged on the conveyor belt 304.

[0030] In specific implementation: When placing the bottle covered with PVC film on the conveyor belt 304 for conveying, the bottle covered with PVC film can be placed in the groove positions 3041 on the conveyor belt 304 in sequence. The groove positions 3041 can accommodate the bottom of the bottle to limit the position of the bottle, thereby preventing the bottle from being dislodged and falling off the conveyor belt 304 during conveying.

[0031] In some embodiments, the fan assembly 50 includes a motor 501, an output shaft 502, and a fan blade 503; the motor 501 is fixedly disposed on the top of the housing 40, the front end of the motor 501 has an output shaft 502, the output shaft 502 of the motor 501 extends inside the housing 40, and the fan blade 503 is fixedly connected to the output shaft 502; the heating element 60 is correspondingly located at the lower end of the fan blade 503.

[0032] In specific implementation: When the fan assembly 50 is running, the output shaft 502 is driven to rotate by the motor 501. When the output shaft 502 rotates, it drives the fan blades 503 to rotate. When the fan blades 503 rotate, they fan the air. The air fanned by the fan blades 503 is heated by the heating element 60 at the lower end and blown towards the bottle covered with PVC film, so that the PVC film on the bottle is heated and sealed.

[0033] In some embodiments, the heating element 60 is a nickel-chromium heating tube.

[0034] In practice: the heating element 60 is a nickel-chromium heating tube, which has the advantage of high heating efficiency, so that the heating element 60 can effectively heat up the air blown out by the fan assembly 50, and generate hot air to heat shrink the PVC film on the bottle.

[0035] In some embodiments, a plurality of rollers 101 are fixedly provided on the bottom of the base 10.

[0036] In practice: when it is necessary to move the heat shrink film device 100 for temperature-controlled hot air sealing bottle cap, the user can push the base 10. When the base 10 is pushed by force, several rollers 101 support the base 10 to move the heat shrink film device 100 for temperature-controlled hot air sealing bottle cap.
