Technical Field

[0001] The utility model relates to the field of food packaging, in particular to a sealing device for powder raw materials used in food production. Background Art

[0002] After the ingredients are mixed in the powder food production workshop, the unused raw materials need to be sealed, and the sealing machine is often used to seal the remaining raw materials. After the sealing is completed, the raw materials are put into the outsourced raw material bags for return. If the seal is not tight, it may cause raw material contamination, waste resources and increase costs.

[0003] In the traditional sealing process, the air in the raw material bag needs to be pressed out first, and then the sealing machine is used to seal it. The commonly used sealing machine is placed flat on the table. During the sealing process, the pressing and hot pressing head moves up and down, so the raw material bag needs to be placed flat on a flat surface before sealing. When the raw material bag is placed flat, the powder raw material is easy to spill out of the bag opening. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments 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 in 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.

[0027] An embodiment of a sealing device for powder raw materials for food production according to the utility model:

[0028] A sealing device for powder raw materials for food production includes a box body 1, wherein there is a space inside the box body 1 for placing a raw material bag containing remaining raw materials to be sealed. The upper end of the box body 1 is open, and a box cover 2 is arranged thereon, and the cross-section of the box cover 2 is an arc shape.

[0029] Blowers 9 are installed on both sides of the box body 1 in the width direction, and exhaust filters 10 are provided at the air inlet of the blower 9 to prevent impurities from entering during the use of the blower 9. The air outlet of the blower 9 faces the inside of the box body 1. By starting the blower 9 to transport air into the box body 1, the pressure in the box body 1 is increased, so that the air in the raw material bag is discharged under the action of pressure. Above the box body 1 is a sealing assembly, including a pulling side panel 4, a flipping side panel 5, a heating assembly 6 and a transformer 7. The sealing assembly is used to perform the sealing operation. The transformer 7 is used to adjust the heating power of the heating wire.

[0030] The heating assembly 6 includes a heating strip 6-1, a high temperature cloth 6-2 and a silicone strip 6-3. The silicone strip 6-3 is mounted on the pulling side panel 4. The pulling side panel 4 is slidably mounted on the top of the box body 1. The pulling side panel 4 can be driven to move in the horizontal direction by a handle. The heating strip 6-1 and the high temperature cloth 6-2 are both mounted on the flip side panel 5, and the flip side panel 5 can be flipped upward by a handle. The raw material bag containing raw materials can be placed into the box body 1 by opening the pulling side panel 4 and the flip side panel 5. After the pulling side panel 4 and the flip side panel 5 are reset, the upper part of the raw material bag to be sealed is sandwiched between the heating strip 6-1 and the silicone strip 6-3 to ensure that the raw materials in the raw material bag will not overflow during the process of being squeezed by pressure. After the air in the raw material bag is discharged, the sealing assembly can be started to seal the raw material bag.

[0031] The middle of the box body 1 is hollow, and a filter screen 3 is detachably provided in the hollow part. The filter screen 3 can filter out the powder entrained in the exhaust gas of the raw material bag, so that the powder will not float into the air, and the difficulty of cleaning the site will not be increased. The filter screen 3 can be removed separately for cleaning and disinfection. The detachable fixing method of the filter screen 3 can be a clamping fixation or a bolt fixation.

[0032] A control panel 8 for controlling the blower 9 and the actuator of the sealing assembly is installed on the front side of the box 1. The working time, temperature and strength of the blower of the sealing assembly can be set through the control panel 8, and the set time, temperature and other parameters can be saved and named so that the values ​​do not need to be reset for subsequent use. Universal wheels 11 are installed at the bottom of the box 1, which can be moved at will as needed.

[0033] The actuator of the sealing assembly includes a heating wire. When the heating wire is working, the heating strip 6-1 will heat up to a set temperature, so that the bag opening material melts and adheres together under pressure. When the sealing setting time is reached, the controller in the control panel 8 turns off the power of the heating strip 6-1, thereby completing the sealing operation. The time setting is the function of the timer, and making the heating wire work regularly under the function of the timer belongs to the prior art, and will not be described in detail in this application.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
