Description

Technical Field

[0001] The utility model relates to the field of sealing machines, in particular to an automatic sealing machine for food packaging boxes. Background Technique

[0002] In food packaging, there are mainly the following reasons for installing a plastic bag inside the packaging box: The plastic bag can effectively block the entry of external moisture and humidity into the packaging box, preventing food from getting damp and deteriorating; for example, for crispy foods such as biscuits and potato chips, getting damp will affect the taste and quality; reduce the loss of moisture in the food, maintain the original moisture content of the food, and extend the freshness of the food; for example, for fresh fruits in the packaging box, without the isolation of the plastic bag, the moisture is easy to evaporate; it can prevent the dust, impurities or chemical substances that the packaging box itself may contain from directly contacting the food, ensuring the hygiene and safety of the food; prevent external pollutants such as dust and insects from entering the packaging box during transportation and storage to contaminate the food; some foods have strong odors, and the plastic bag can prevent these odors from penetrating into the packaging box, avoiding affecting other foods or causing odor residues in the packaging box; at the same time, it can also prevent the odors that the packaging box may emit from being absorbed by the food, maintaining the original taste of the food; the smooth surface of the plastic bag makes it easier to put the food into the packaging box and will not be scratched or damaged by the rough inner wall of the packaging box;

[0003] When sealing the plastic bag inside the packaging box, generally a sealing machine is used to seal the plastic bag inside the packaging box by means of heat melting. The sealing method is single-channel sealing, and it is easy for the food inside the plastic bag to leak, resulting in the contamination of the food (such as biscuits and dried fruits). Content of the Utility Model

[0004] The purpose of the utility model is to provide an automatic sealing machine for food packaging boxes to solve the defects mentioned in the above background technique.

[0005] To achieve the above purpose, an automatic sealing machine for food packaging boxes is provided, including a driving cover. Guide holes are opened on both sides of the driving cover, and the sizes of the guide holes are adapted to those of the guide rods. At the same time, the guide rods are inserted into the guide holes. At the same time, the bottom of the guide rods is fixedly installed on the surface of the base. And a battery compartment is opened on the right side of the bottom of the base, and the size of the battery compartment is adapted to that of the cover plate. At the same time, the cover plate is inserted through the surface of the battery compartment. The bottom of the driving cover is fixedly installed with a second sealing seat, and a first sealing seat is arranged at the bottom of the second sealing seat. At the same time, the bottom of the first sealing seat is fixedly connected to a heat transfer sheet. Springs are installed on the outer sides of the guide rods.

[0006] Preferably, the first sealing seat and the second sealing seat are arranged in parallel, and the distance between the first sealing seat and the second sealing seat is 1.5 cm.

[0007] Preferably, both the first sealing seat and the second sealing seat are powered and heated by a power source installed inside the battery compartment, and the length of the first sealing seat is less than that of the second sealing seat.

[0008] Preferably, a carrier is fixedly installed at the bottom of the heat transfer sheet, and the carrier covers the surface of the base and is fixedly connected by a fixing bolt. The carrier, the heat transfer sheet, the first sealing seat, and the second sealing seat are all rectangularly arranged.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Please refer to Figures 1-4 , the utility model provides an automatic sealing machine for food packaging boxes, which includes a driving cover 1. Guide holes are opened on both sides of the driving cover 1, and the sizes of the guide holes are adapted to those of the guide rods 2. At the same time, the guide rods 2 are inserted into the interior of the guide holes. Meanwhile, the bottom of the guide rods 2 is fixedly installed on the surface of a base 4, and a battery compartment 12 is opened on the right side of the bottom of the base 4. The size of the battery compartment 12 is adapted to that of a cover plate 5. At the same time, the cover plate 5 is inserted through the surface of the battery compartment 12. The bottom of the driving cover 1 is fixedly installed with a second sealing seat 10, and a first sealing seat 9 is arranged at the bottom of the second sealing seat 10. At the same time, the bottom of the first sealing seat 9 is fixedly connected to a heat transfer sheet 8, and springs 3 are installed on the outer sides of the guide rods 2.

[0018] Working principle: Place the plastic packaging bag inside the packaging box between the first sealing seat 9 and the second sealing seat 10. The driving cover 1 moves downward, causing the second sealing seat 10 to move downward, so that the two upper sealing strips 101 at the bottom of the second sealing seat 10 are respectively inserted into the two lower sealing grooves 91. The end of the plastic packaging bag is heated and melted to form two seals. The two seals greatly reduce the possibility of air leakage. For example, when packaging nuts that are prone to oxidation, better sealing can extend their shelf life; the food inside the plastic bag is not easily leaked, avoiding food contamination; it effectively prevents the leakage of liquid or finely granular food, such as packaging foods with more soup or powdered seasonings.

[0019] As a preferred embodiment, the first sealing seat 9 and the second sealing seat 10 are arranged in parallel, and the distance between the first sealing seat 9 and the second sealing seat 10 is 1.5 cm.

[0020] Both the first sealing seat 9 and the second sealing seat 10 are powered and heated by a power source installed inside the battery compartment 12, and the length of the first sealing seat 9 is less than that of the second sealing seat 10.

[0021] Both the first sealing seat 9 and the second sealing seat 10 are powered and heated by a power source installed inside the battery compartment 12; the temperatures of the first sealing seat 9 and the second sealing seat 10 increase, and double-channel sealing work is carried out on the packaging bag; the strength of the sealed part is increased, enabling it to withstand greater external pressure; during transportation or storage, even if it is squeezed, it is not easily broken or opened;

[0022] For some foods that have a certain degree of expansibility themselves, such as fermented foods, the two seals can better cope with the internal pressure; reduce the risk of accidental opening of the seal, especially for foods that may be accessed by children, improving safety; if the first seal has problems, the second seal can still play a certain protective role to ensure that the food is not contaminated;

[0023] As a preferred embodiment, a carrier 7 is fixedly installed at the bottom of the heat transfer sheet 8, and the carrier 7 covers the surface of the base 4 and is fixedly connected by a fixing bolt 11. The carrier 7, the heat transfer sheet 8, the first sealing seat 9 and the second sealing seat 10 are all rectangularly arranged.

[0024] A positioning track 6 is provided at the surface opening of the battery compartment 12, and the positioning track 6 is adapted to the size of the cover plate 5. At the same time, the cover plate 5 is inserted into the positioning track 6, and the cross-sections of the cover plate 5 and the positioning track 6 are both "T"-shaped.

[0025] Upper sealing strips 101 are fixedly arranged on both sides of the bottom of the second sealing seat 10, and lower sealing grooves 91 are provided on both sides of the surface of the first sealing seat 9. At the same time, the lower sealing grooves 91 are adapted to the size of the upper sealing strips 101, and the upper sealing strips 101 are inserted into the lower sealing grooves 91. The cross-sections of the lower sealing grooves 91 and the upper sealing strips 101 are both "V"-shaped.

[0026] An electric push rod can be installed on the driving cover 1. Through the electric push rod, the driving cover 1 can be automatically lifted and lowered to automatically seal the packaging bag inside the packaging box.
