Description

Technical Field

[0001] The utility model relates to a packaging table, in particular to a vacuum packaging table. Background Technique

[0002] With the development of technology, in the fields of people's life and work, various vacuum packagings are everywhere, and the supply and demand have greatly increased. Through vacuum packaging, the purpose is to reduce the oxygen content in the packaging, prevent the mildew and deterioration of packaged food, maintain the color, aroma and taste of food, and extend the shelf life. When performing vacuum packaging, a vacuum packaging table is required.

[0003] For example, a liftable vacuum packaging workbench of a food packaging machine with a publication number of CN216070847U disclosed in the Chinese patent includes a chute, a slide bar, a lead screw, a threaded port and a placement table. Chutes are provided on both sides of the long end of the machine body. A slide bar is provided in each chute. A cross plate is connected between the slide bars. A support rod is provided on each slide bar. The support rods are all arranged under the placement table. A motor slot is opened on the machine body.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 - 4 , the present invention provides a technical solution: a vacuum packaging table, including a frame 1, a first placement table 2 is arranged on the front surface of the frame 1, one end of the first placement table 2 is hinged to a second placement table 3 through a hinge, triangular brackets 201 are symmetrically and fixedly connected to the positions near the two side edges under the first placement table 2, dovetail sliders 202 are fixedly installed on the inner walls of the triangular brackets 201, dovetail chutes 103 are opened on both sides of the frame 1, the dovetail chutes 103 are slidably matched with the dovetail sliders 202, two connecting shafts 203 are symmetrically and fixedly installed under the first placement table 2, and a support plate 5 is rotatably installed on the connecting shafts 203.

[0022] In this implementation scheme, through the sliding fit of the dovetail chute 103 and the dovetail slider 202, the triangular bracket 201 is slidably connected to the frame 1. The triangular bracket 201 is fixedly connected to the first placement table 2, so as to support the first placement table 2 in front of the frame 1. There are no grooves opened on the front surface of the frame 1, and the back surface of the first placement table 2 fits against the front surface of the frame 1, so as to ensure that the packaging bags or finished products placed on the first placement table 2 will not fall into the grooves, resulting in damage to the packaging bags. Secondly, the first placement table 2 and the second placement table 3 are hinged together through a hinge, so that the second placement table 3 can be rotated and unfolded. As Figure 1 , 3 shown, the support plate 5 supports the second placement table 3 from below, avoiding damage to the hinge due to the force on the second placement table 3. The first placement table 2 and the second placement table 3 will form a larger placement table, which is convenient for packaging large objects. At the same time, when packaging small objects, when the second placement table 3 is folded above the first placement table 2, the occupied space can be reduced. As Figure 2 shown.

[0023] Among them, in order to achieve the purpose of adjusting the height of the placement table, the present device adopts the following technical solutions: A control console 101 is fixedly connected to the upper surface of the frame 1. A clamping plate 102 is arranged on the control console 101. A convex edge 4 is fixedly installed on the front surface of the frame 1. A hydraulic telescopic rod 401 is fixedly installed on the convex edge 4. The upper end of the hydraulic telescopic rod 401 is fixedly connected to the first placement table 2.

[0024] By fixedly connecting the hydraulic telescopic rod 401 to the first placement table 2, starting the hydraulic telescopic rod 401 can drive the first placement table 2 to move up and down, thereby adjusting the height of the placement table.

[0025] Among them, in order to achieve the purpose of folding, the present device adopts the following technical solutions: Threaded fixing holes 301 are opened on the lower surface of the second placement table 3. A rubber plug 302 is arranged in the threaded fixing holes 301. A rotating connection hole 501 is opened at a position near one end edge inside the support plate 5. The rotating connection hole 501 cooperates with the connecting shaft 203. A connection through hole 502 is opened at a position near the other end edge inside the support plate 5. A fixing bolt 503 is arranged in the connection through hole 502. The fixing bolt 503 is in threaded cooperation with the threaded fixing holes 301.

[0026] When the second placement table 3 is in the folded state, the threaded fixing holes 301 will face upward, as Figure 2 shown. At this time, the lower surface of the second placement table 3 is the working surface. The rubber plug 302 can block the inside of the threaded fixing holes 301 to prevent impurities from falling and blocking the threaded fixing holes 301. After the fixing bolt 503 passes through the connection through hole 502 and is screwed into the inside of the threaded fixing holes 301, the support plate 5 can provide a certain supporting force for the second placement table 3. The support plate 5 is rotationally installed under the first placement table 2 through the rotational cooperation of the rotating connection hole 501 and the connecting shaft 203.

[0027] The working principle and usage process of the present utility model: When in use, the device needs to be placed in a suitable position. Starting the hydraulic telescopic rod 401 can drive the first placement table 2 to move. The movement of the first placement table 2 will synchronously drive the second placement table 3 to move, thereby adjusting the height of the placement table composed of the first placement table 2 and the second placement table 3. After the fixing bolt 503 is screwed out of the inside of the threaded fixing holes 301, the restriction on the support plate 5 can be released. At this time, the support plate 5 can be rotated 90 degrees and hidden under the first placement table 2. After the second placement table 3 loses the restriction of the support plate 5, it can be flipped 180 degrees and folded above the first placement table 2, as Figure 2 shown, thereby reducing the space occupied by the placement table.

[0028] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
