Description

Technical Field

[0001] This utility model relates to the field of sealing machine technology, specifically a simple sealing machine for pastry packaging. Background Technology

[0002] A simple sealing machine is a device used to seal packaging bags for pastries, effectively maintaining product freshness and preventing air from entering, thus extending shelf life. Sealing machines are especially important for pastries because they ensure airtight packaging, preventing moisture and contamination, and are convenient and quick to use.

[0003] Currently, most hand-operated pliers sealing machines on the market seal packaging bags by gradually sealing the bags using a positioning shaft on one side of the machine as the center. During the sealing process, the heating wire on the side of the positioning shaft contacts the packaging bag first to heat and seal it. This may result in the sealing temperature of this part being too high or the heating time being too long, making the seal quality on this side more secure, while the other side may be heated unevenly or for insufficient time, resulting in lower sealing strength and poor sealing effect.

[0004] Therefore, a simple sealing machine for pastry packaging is proposed to address the above problems. Utility Model Content

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 scope of protection of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a simple sealing machine for pastry packaging, including a base 1. A positioning plate 2 is fixedly installed on one side of the top of the base 1. A positioning shaft 3 is fixedly installed inside the positioning plate 2. A pressure plate 4 is sleeved on the surface of the positioning shaft 3. Connecting ears 5 are fixedly installed on both sides of the pressure plate 4 near the end of the positioning shaft 3. T-shaped rods 6 are fixedly installed at the four corners of the top of the positioning plate 2. Springs 7 are movably installed on the surface of the T-shaped rods 6. A stop plate 8 is movably installed on the surface of the T-shaped rods 6 and on top of the springs 7. A mounting base 9 is fixedly installed at the bottom of the stop plate 8. A first electric heating rod 10 is fixedly installed inside the mounting base 9.

[0024] Reference Figure 1 , Figure 2 , Figure 3 Through the structural design of T-shaped rod 6, spring 7, abutment plate 8, mounting base 9, and first heating rod 10, and through the cooperation between the structures, the function of heating and uniform pressure distribution is achieved. Thus, by pressing the spring 7, the heating rod is driven to fall vertically to contact the packaging bag, thereby making the contact of the heating rod more uniform, ensuring consistent sealing pressure distribution, and avoiding uneven or incorrect sealing due to angle changes.

[0025] A through groove 11 is fixedly opened at the bottom of the abutment plate 8, and a handle 12 is fixedly installed on the side of the abutment plate 8 away from the connecting ear 5.

[0026] Reference Figure 2 and Figure 3The through slot 11 provides space for the first heating rod 10 to move, thus meeting the requirement for the first heating rod 10 to be able to lift vertically. The handle 12 allows the user to operate it manually, thereby driving the pressure plate 4 to adjust the angle, avoiding accidental contact with the heating rod by the user, thus increasing the safety of the overall device.

[0027] A torsion spring 13 is fitted in the middle of the surface of the positioning shaft 3. One end of the torsion spring 13 is attached to the bottom surface of the pressure plate 4, and the other end of the torsion spring 13 is attached to the top surface of the base 1.

[0028] Reference Figure 1 The torsion spring 13 facilitates the provision of a reverse force, thereby helping the pressure plate 4 return to its initial position after the sealing operation is completed, thus enabling the device to have an automatic reset function.

[0029] A slot 14 is provided in the middle of the top of the base 1, and a second electric heating rod 15 is fixedly installed inside the slot 14.

[0030] Reference Figure 1 The slot 14 provides space for the deployment of the second heating rod 15, which provides additional heat to the bottom heating area of ​​the packaging bag, helping to improve sealing efficiency. At the same time, it works with the first heating rod 10 to complete the full sealing of the packaging bag, ensuring the strength of the seal.

[0031] A cavity 16 is provided on the top of the base 1, and a positioning hole 17 is provided on one side of the cavity 16.

[0032] Reference Figure 2 The cavity 16 provides space for storing the battery 19 and the micro inverter 20.

[0033] A sealing cover 18 is fixedly installed at the bottom of the base 1. A storage battery 19 is fixedly installed on one side of the top of the sealing cover 18. A micro inverter 20 is fixedly installed on the other side of the top of the sealing cover 18. The micro inverter 20 is connected to the storage battery 19 by wires. The micro inverter 20 is also connected to the first heating rod 10 and the second heating rod 15 by wires.

[0034] Reference Figure 2 and Figure 4 The sealing cover 18 facilitates the closure of the bottom opening of the cavity 16, thereby reducing interference from the external environment to the internal electrical components and ensuring the service life of the device. The battery 19 facilitates the temporary storage of power for use by the first heating rod 10 and the second heating rod 15, thereby increasing the flexibility of the device and enabling the sealing machine to work independently to meet the needs of portable use scenarios. The micro inverter 20 facilitates the conversion of the DC power from the battery 19 into AC power suitable for the heating rods, thereby ensuring the normal operation of the heating function of the heating rods.

[0035] Working principle: When using this device, place the sealing area of ​​the packaging bag on the top of the base 1. Press the handle 12 to drive the pressure plate 4 to rotate around the positioning shaft 3 and then fit against the base 1. The pressure plate 4 presses the top surface of the packaging bag, and the base 1 holds the bottom surface of the packaging bag to complete the packaging bag fixation. Manually press the abutment plate 8, which presses the spring 7. The spring 7 deforms under pressure, providing space for the abutment plate 8 to descend. The abutment plate 8 drives the mounting base 9 to move and descend inside the slot 14. The mounting base 9 drives the first heating rod 10 to fit against the top surface of the packaging bag. The first heating rod 10 and the second heating rod 15 are activated to seal the packaging bag simultaneously. During this process, the power of the battery 19 is converted by the micro inverter 20 and supplied to the heating rods. After sealing, release the abutment plate 8 and handle 12. The torsion spring 13 releases the torque to drive the pressure plate 4 to reset, ready for resealing.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
