Description

Technical Field

[0001] This utility model relates to the field of vacuum packaging machine technology, and in particular to a clean vacuum packaging machine. Background Art

[0002] Vacuum packaging machines can automatically extract air from packaging bags and seal them after reaching a predetermined vacuum level. They can also be filled with nitrogen or other mixed gases before sealing. They are commonly used in the food industry because vacuum packaging helps food resist oxidation and thus achieves long-term preservation.

[0003] When using a vacuum packaging machine, the operator needs to place the packaging bag into the lower vacuum chamber to create a vacuum between the upper and lower vacuum chambers. Then, the vacuum pump is started to extract the air from the packaging bag until the predetermined vacuum level is reached. After sealing, the vacuum pump is stopped to release the pressure inside the bag, thus completing the packaging process.

[0004] In practical use, existing technologies suffer from dirt and debris buildup on packaging bags due to the food itself affecting the bags during filling. This dirt and debris adhere to the lower vacuum chamber, impacting the quality and effectiveness of subsequent food packaging. Therefore, a clean vacuum packaging machine is proposed.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Example 1

[0028] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present invention. This embodiment provides a clean vacuum packaging machine, including a vacuum packaging machine body 1 and a universal wheel 101. The universal wheel 101 is fixedly installed on the lower surface of the vacuum packaging machine body 1. A lower vacuum chamber 102 is provided on the upper surface of the vacuum packaging machine body 1. A cleaning component 2 is provided inside the vacuum packaging machine body 1.

[0029] Specifically, the cleaning component 2 includes a groove 201 formed inside the vacuum packaging machine body 1. A motor 202 is fixedly connected inside the groove 201. A two-way lead screw 203 is provided at the output shaft end of the motor 202 and inside the groove 201. A transmission sprocket 206 is fixedly connected to the outer surface of the two two-way lead screws 203. A transmission chain 207 is movably connected to the outer surface of the two transmission sprockets 206. Two threaded sleeves 204 are threadedly connected to the outer surface of the two two-way lead screws 203. A cleaning brush 205 is fixedly connected between the threaded sleeves 204.

[0030] Furthermore, the starter motor 202 drives the bidirectional lead screw 203 to rotate. Through the cooperation of the two transmission sprockets 206 and the transmission chain 207, the two bidirectional lead screws 203 can rotate synchronously. When the bidirectional lead screw 203 rotates, it drives the two threaded sleeves 204 to move closer to each other. When the threaded sleeves 204 move, they drive the cleaning brush 205 to move, so that the cleaning brush 205 sweeps away the dirt and debris in the lower vacuum chamber 102, and the dirt and debris fall into the recycling bin for storage. This can prevent dirt and debris from adhering in the lower vacuum chamber 102 and affecting the quality and effect of subsequent food packaging, so as to reduce the wear and tear of dirt and debris on the equipment.

[0031] Example 2

[0032] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, and a sealing component 3 is provided on the upper surface of the vacuum packaging machine body 1.

[0033] Specifically, the sealing assembly 3 includes a fixing plate 301 disposed on the outer surface of the vacuum packaging machine body 1, an upper vacuum chamber 302 disposed between the fixing plates 301, a first sealing gasket 303 disposed on the lower surface of the upper vacuum chamber 302, two locking blocks 305 fixedly connected to the lower surface of the upper vacuum chamber 302, a locking groove 306 fixedly connected to the upper surface of the vacuum packaging machine body 1, the locking groove 306 and the locking blocks 305 engaging with each other, a second sealing gasket 304 disposed on the upper surface of the upper vacuum chamber 302, a positioning groove 307 opened inside the locking groove 306 and the locking blocks 305, a positioning block 308 movably connected inside the positioning groove 307, a moving rod fixedly connected to the outer surface of the positioning block 308, a spring 309 sleeved and connected to the outer surface of the moving rod, and a pull plate fixedly connected to the outer surface of the moving rod through the locking groove 306.

[0034] Furthermore, when the upper vacuum chamber 302 moves, it will cause the locking block 305 to engage with the locking groove 306. At the same time, when the locking block 305 moves downward, it will touch the positioning block 308, causing the positioning block 308 to move under the action of the spring 309 and the moving rod. Further, when the locking block 305 engages with the locking groove 306, the elasticity of the spring 309 will cause the positioning block 308 to engage with the positioning groove 307, so that the upper vacuum chamber 302 and the lower vacuum chamber 102 come into contact. When the upper vacuum chamber 302 and the lower vacuum chamber 102 come into contact, the first sealing gasket 303 and the second sealing gasket 304 will be squeezed against each other to form a seal and prevent gas leakage. This can improve the sealing performance between the upper vacuum chamber 302 and the lower vacuum chamber 102, so as to ensure the vacuum degree inside the packaging bag.

[0035] Working Principle: During use, the operator moves the device to the designated position using the casters 101 on the lower surface of the vacuum packaging machine body 1, and then fixes the vacuum packaging machine body 1 in place. Since the specific structure and working principle of the device are existing technologies well-known to those skilled in the art, they will not be elaborated upon here. After the work is completed, the operator starts the motor 202 to drive the bidirectional lead screw 203 to rotate. Through the cooperation of the two transmission sprockets 206 and the transmission chain 207, the two bidirectional lead screws 203 can be driven to rotate synchronously. Furthermore, when the bidirectional lead screws 203 rotate, they will drive the two threaded sleeves 204 to move closer to each other. When the threaded sleeve 204 moves, it drives the slider 209 to slide within the slide rail 208, thus supporting and limiting the threaded sleeve 204 and improving the overall stability of the device. Furthermore, when the threaded sleeve 204 moves, it drives the cleaning brush 205 to move, causing the cleaning brush 205 to sweep away dirt and debris in the lower vacuum chamber 102. The dirt and debris fall into the recycling bin for storage, thereby preventing dirt and debris from adhering to the lower vacuum chamber 102 and affecting the quality and effect of packaging other foods later. This reduces the wear and tear on the equipment caused by dirt and debris, thereby improving the packaging effect and cleanliness of the vacuum packaging machine body 1.

[0036] In use, after placing the packaging bag to be vacuum-packed in the lower vacuum chamber 102, the operator operates the control panel to move the fixing plate 301, causing the upper vacuum chamber 302 to move downwards. When the upper vacuum chamber 302 moves, it causes the locking block 305 to engage with the locking slot 306. Simultaneously, as the locking block 305 moves downwards, it touches the positioning block 308, causing the positioning block 308 to move under the action of the spring 309 and the moving rod. Further, when the locking block 305 engages with the locking slot 306, the spring 309... The elasticity of the 9-type positioning block 308 engages with the positioning groove 307 to bring the upper vacuum chamber 302 into contact with the lower vacuum chamber 102. When the upper vacuum chamber 302 and the lower vacuum chamber 102 are in contact, the first sealing gasket 303 and the second sealing gasket 304 will be squeezed against each other to form a seal and prevent gas leakage. This will improve the sealing performance between the upper vacuum chamber 302 and the lower vacuum chamber 102, so as to ensure the vacuum degree inside the packaging bag, improve the packaging effect, and prevent dust, impurities and other substances from entering the device.
