Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a cleaning and drying device for vacuum packaging bags. Background Technology

[0002] Vacuum packaging bags are widely used in food processing, pharmaceutical packaging, and electronic component storage due to their excellent sealing and preservation properties. However, during reuse or recycling, stains, oils, or corrosive residues can easily remain on the surface and inside of vacuum packaging bags. If not thoroughly cleaned, this can not only affect the hygiene and safety of reuse but may also lead to odors or bacterial growth due to the deterioration of these residues. Furthermore, if cleaned vacuum packaging bags are not dried quickly and evenly, residual moisture can also cause microbial growth, reducing the bags' reusability.

[0003] Currently, traditional vacuum packaging bag cleaning methods mostly rely on manual brushing or simple spraying devices, which have the following shortcomings: Firstly, manual cleaning is inefficient and difficult to adapt to the needs of large-scale processing, and the cleaning force is uneven, easily resulting in localized stains. Secondly, simple spraying devices lack effective stirring and turning mechanisms, causing packaging bags to easily stack together during the cleaning process, leading to insufficient cleaning of the contact surfaces and poor cleaning results. In addition, the drying process after cleaning often uses natural air drying or direct hot air blowing. Natural air drying is greatly affected by environmental factors and has a long drying cycle; direct hot air blowing is prone to causing localized overheating and damage to the packaging bags due to uneven temperature distribution. At the same time, traditional drying equipment and cleaning equipment are often independent of each other, requiring manual transfer of packaging bags, increasing the number of operation steps and labor intensity, and also increasing the risk of secondary contamination. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides the following technical solution: a cleaning and drying device for vacuum packaging bags, comprising:

[0005] The support part includes a support shell; a support top cover is rotatably provided on the top of the support shell; and a support base is fixedly provided on the bottom of the support shell.

[0006] The cleaning unit is located inside the bearing shell. The cleaning unit includes a cleaning tank that is rotatably installed inside the bearing shell. A second cleaning gear disk is fixedly installed on the cleaning tank. A stirring assembly is detachably installed at the center of the cleaning tank. The stirring assembly includes a cleaning shaft. A cleaning vent head and a cleaning paddle are fixedly installed on the cleaning shaft.

[0007] The ventilation section is disposed on the support shell. The ventilation section includes a ventilation shell one fixedly disposed on the support shell. One end of the ventilation shell one is disposed on the top cover of the support shell through a ventilation pipe, and the other end of the ventilation shell one is fixedly disposed on the outer shell of the ventilation shell.

[0008] Furthermore, a venting resistance heating wire is fixedly installed inside the venting shell, and the venting shell is made of stainless steel.

[0009] Furthermore, a second ventilation shaft and a first ventilation shaft are rotatably disposed inside the ventilation housing, and the second ventilation shaft and the first ventilation shaft are slidably engaged. The second ventilation shaft is fixedly disposed on the cleaning transmission shaft, and the cleaning transmission shaft meshes with the second cleaning gear disc through a bevel gear.

[0010] Furthermore, the cleaning shaft, cleaning paddle, and cleaning vent head are all hollow structures, and the cleaning vent heads are arranged in a circular array along the rotation center of the cleaning shaft.

[0011] Furthermore, a cleaning sealing gasket is rotatably provided on the top of the cleaning shaft, and the bottom of the cleaning shaft is detachably mounted on the first cleaning gear disk via a spline, and the first cleaning gear disk is rotatably mounted on the support base.

[0012] Furthermore, the first cleaning gear disk meshes with a cleaning bevel gear fixedly mounted on the output shaft of the cleaning motor, and the cleaning bevel gear meshes with the second cleaning gear disk.

[0013] Furthermore, the vent pipe is made of high-temperature resistant silicone rubber material.

[0014] The advantages of this utility model compared with the prior art are:

[0015] 1. Significantly improves cleaning effect and ensures thorough cleaning; This device innovatively adopts a reverse rotation design between the cleaning tank and the stirring component. The cleaning tank rotates clockwise under the drive of the second cleaning gear disc, while the cleaning blades of the stirring component rotate counterclockwise under the drive of the first cleaning gear disc, creating strong relative motion and water flow disturbance. This reverse stirring structure can fully tumble and knead the packaging bags, completely breaking the problems of easy stacking of packaging bags and insufficient cleaning of contact surfaces in traditional spray devices, ensuring that every surface can fully contact the cleaning liquid. At the same time, the cleaning air head continuously sprays bubbles into the water through a hollow structure. The impact force generated when the bubbles burst further enhances the stain removal effect, achieving efficient removal of stubborn stains such as oil stains and corrosive residues, and significantly reducing the risk of local stain residue.

[0016] 2. Achieve rapid and uniform drying, enhancing reuse safety: This device integrates centrifugal dehydration and hot air circulation in its drying process. After washing, there is no need to transfer the packaging bags; the surface moisture is quickly removed by the centrifugal force generated by the high-speed rotation of the washing drum, shortening the subsequent drying time. The ventilation section heats the air through a resistance heating wire and delivers it to the inside of the housing via a ventilation pipe. The hot air is evenly distributed under the airflow disturbance created by the rotation of the washing drum, avoiding the localized overheating problem caused by direct hot air blowing in traditional methods. The heated air can penetrate the gaps in the packaging bags, accelerating moisture evaporation. Combined with the low moisture content after centrifugal dehydration, this significantly shortens the drying cycle. Furthermore, the entire drying process is carried out in a closed environment, reducing the risk of secondary contamination.

[0017] 3. Optimized operation process and reduced labor intensity: This device integrates washing and drying functions into one unit, eliminating the need for manual transfer of packaging bags between the washing and drying equipment, thus reducing operational steps. The top cover can be rotated and opened for easy insertion and removal of packaging bags; the washing shaft is connected to the washing gear disc via a spline, enabling quick disassembly of the stirring components for convenient cleaning and maintenance. Water inlet and outlet are automatically controlled by solenoid valves, minimizing manual intervention. The entire washing and drying process requires only initial feeding and final unloading, significantly reducing labor intensity, improving processing efficiency, and meeting the needs of large-scale processing.

[0031] like Figures 1 to 9As shown, the cleaning unit 1 is disposed inside the bearing shell 302. The cleaning unit 1 includes a stirring assembly, a first cleaning gear disk 101, a cleaning sealing gasket 104, a cleaning tank 106, a cleaning motor 107, a cleaning bevel gear 108, a second cleaning gear disk 109, and a cleaning drive shaft 110. The cleaning tank 106 is rotatably disposed inside the bearing shell 302. The second cleaning gear disk 109 is fixedly disposed on the cleaning tank 106. The stirring assembly is detachably disposed at the center of the cleaning tank 106. The stirring assembly includes a cleaning shaft 105, a cleaning vent head 102, and a cleaning paddle 103. The cleaning vent head 102 and the cleaning paddle 103 are fixedly disposed on the cleaning shaft 105. The cleaning shaft 105, the cleaning paddle 103, and the cleaning vent head 102 are all hollow structures. The cleaning vent head 102 is distributed in a circular array along the rotation center of the cleaning shaft 105. A cleaning sealing gasket 104 is rotatably mounted on the top of the cleaning shaft 105, and the bottom of the cleaning shaft 105 is detachably mounted on the first cleaning gear disk 101 via a spline. The first cleaning gear disk 101 is rotatably mounted on the support base 303. The first cleaning gear disk 101 meshes with the cleaning bevel gear 108 fixedly mounted on the output shaft of the cleaning motor 107, and the cleaning bevel gear 108 meshes with the second cleaning gear disk 109.

[0032] like Figures 1 to 9 As shown, the ventilation section 2 is mounted on the support shell 302. The ventilation section 2 includes a ventilation shaft 201, a second ventilation shaft 202, a ventilation resistance heating wire 203, a first ventilation shell 204, a ventilation pipe 205, and a second ventilation shell 206. The first ventilation shell 204 is fixedly mounted on the support shell 302. One end of the first ventilation shell 204 is mounted on the support top cover 301 via the ventilation pipe 205, and the other end is fixedly mounted on the second ventilation shell 206. The ventilation resistance heating wire 203 is fixedly mounted inside the first ventilation shell 204, which is made of stainless steel. The second ventilation shaft 202 and the first ventilation shaft 201 are rotatably mounted inside the second ventilation shell 206, and are in sliding engagement with each other.

The vent tube 205 is made of high-temperature resistant silicone rubber.

[0033] like Figures 1 to 9 As shown, the present invention discloses a cleaning and drying device for vacuum packaging bags, the working principle of which is as follows:

[0034] During cleaning, the operator places the packaging bag to be cleaned inside the cleaning tank 106, connects the water inlet on the top cover 301 to the water inlet system, opens the solenoid valve to put water for cleaning into the housing 302, and turns on the cleaning motor 107. The rotation of the cleaning motor 107 drives the cleaning bevel gear 108, which in turn drives the second cleaning gear disc 109, the first cleaning gear disc 101, and the cleaning drive shaft 110 to rotate together. When the second cleaning gear disc 109 rotates, it drives the cleaning tank 106 to rotate clockwise, and when the first cleaning gear disc 101 rotates, it drives the cleaning shaft 105, the cleaning vent head 102, and the cleaning lever 103 to rotate counterclockwise. The cleaning paddle 103 rotates counterclockwise and the cleaning tub 106 rotates clockwise simultaneously, stirring and cleaning the vacuum-packed bags inside the cleaning tub 106. At the same time, the cleaning drive shaft 110 rotates, driving the second ventilation shaft 202 and the first ventilation shaft 201 to rotate, delivering air from the air inlet at the bottom of the ventilation housing 206 through the ventilation housing 206, the first ventilation housing 204, and the ventilation pipe 205 to the cleaning paddle 103, the cleaning ventilation head 102, and the cleaning shaft 105. Finally, the air is sprayed out from the cleaning ventilation head 102 into the water inside the cleaning tub 106, generating bubbles to aid in the cleaning process and make it more thorough.

[0035] After cleaning, open the solenoid valve on the drain outlet to drain the water. The operator then opens the top cover 301 and removes the cleaning sealing gasket 104, cleaning paddle 103, cleaning vent head 102, and cleaning shaft 105 from the cleaning gear disc 101 and cleaning tank 106. The cleaning motor 107 is then turned on. The rotation of the cleaning motor 107 drives the cleaning bevel gear 108, which in turn drives the cleaning gear disc 109 and cleaning tank 106 to rotate together. Under centrifugal force, the water on the surface of the packaging bag inside the cleaning tank 106 is flung out. Simultaneously, the power supply to the venting resistor heating wire 203 is turned on. Heating wire 203 generates heat, and the rotation of cleaning drive shaft 110 drives ventilation shaft 202 and ventilation shaft 201 to rotate, which in turn transports air from the air inlet at the bottom of ventilation housing 206 through ventilation housing 206, ventilation housing 204, and ventilation pipe 205 to the bearing housing 302. During this process, the flowing air transports the heat generated by ventilation resistance heating wire 203 to the bearing housing 302 and the cleaning tank 106. The air is finally discharged from the drain, which increases the air flow in the cleaning tank 106. Combined with centrifugal force and the heat generated by ventilation resistance heating wire 203, it accelerates the drying of moisture and improves processing efficiency.
