Detailed Embodiments

[0023] 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.

[0024] Embodiment

[0025] Such as Figures 1-3As shown in the figure, the present utility model provides a pressing mechanism 2 for a salt packaging bag, including: a conveying bed 1 and a pressing mechanism 2. Device plates 100 are horizontally extended along both edges of the conveying bed 1. The pressing mechanism 2 is arranged on the device plates 100. The pressing mechanism 2 includes: a moving cylinder 200, a moving block 210, a pressing plate 220, and a fixed block 230. The moving cylinder 200 is arranged on the device plate 100. The output shaft of the moving cylinder 200 is perpendicular to the conveying direction of the conveying bed 1. The moving block 210 is connected to the output shaft of the moving cylinder 200. Connecting columns 211 extend from both sides of the moving block 210. The lower end of the pressing plate 220 is rotatably connected to the connecting columns 211. The fixed block 230 is correspondingly arranged on the side of the pressing plate 220 away from the moving block 210. The upper end of the fixed block 230 is rotatably connected to the middle end of the pressing plate 220. As Figure 1 shown, controlling the moving cylinder 200 to move the moving block 210 backward can press the pressing plate 220 against the salt packaging bag on the conveying bed 1, thereby realizing the pressing of the salt packaging bag for subsequent sealing. Preferably, brackets are arranged on both sides of the conveying bed 1, and a sealing device is arranged on the brackets. Controlling the reciprocating movement of the output shaft of the moving cylinder 200 realizes the repeated pressing of the salt packaging bag on the conveying bed 1. It should be noted that,

[0026] in this embodiment, as Figures 2-3 shown, it further includes: a guide rail 3. The guide rail 3 is fixed on the device plate 100. A sliding groove 212 is arranged on the bottom surface of the moving block 210. The sliding groove 212 is restricted to move on the guide rail 3. The arrangement of the guide rail 3 facilitates the repeated movement of the moving cylinder 200, and the arrangement of the guide rail 3 defines the moving path of the moving block 210.

[0027] In this embodiment, the fixed block 230 is fixed on the device plate 100 by screws.

[0028] In this embodiment, connection holes 221 are arranged on the pressing plate 220. It further includes a plurality of adjusting plates 4. A limiting rod 400 is arranged on one side of the adjusting plate 4. The limiting rod 400 is detachably limited in the connection holes 221. A plurality of protrusions 410 are arranged on the side of the adjusting plate 4 away from the limiting rod 400. The protrusions 410 can contact the salt packaging bag. The arrangement of the adjusting plate 4 increases the adaptability of the device, and can be replaced and adjusted in time according to the specifications of the salt packaging bags on the conveying bed 1. At the same time, in order to avoid hard contact between the adjusting plate 4 and the conveying bed 1, a plurality of springs can be arranged on the side of the adjusting plate 4 close to the pressing plate 220. The springs can play a role in buffering between the adjusting plate 4 and the conveying bed 1 or the packaging belt of the bagged edible salt conveyed on the conveying bed 1.

[0029] In this embodiment, it is preferable to equidistantly arrange a plurality of partition plates 110 on the conveying bed 1. The arrangement of the partition plates 110 can limit the position of the salt packaging bags on the conveying bed 1. When the salt packaging bags restricted between two partition plates 110 move to the position of the pressing mechanism 2, the moving cylinder 200 presses the salt packaging bags, and the sealing device seals the pressed salt packaging bags. After the sealing device completes the sealing, the moving cylinder 200 controls the moving block 210 to move forward to lift the pressing plate 220, and the conveying bed 1 moves to move the next salt packaging bag to the position of the pressing mechanism 2.
