Description

Technical Field

[0001] The utility model relates to a clamping device suitable for sewing cigarette packages, belonging to the technical field of leaf threshing and re-drying sack clamping devices. Background Art

[0002] During the flue-cured tobacco operation, tobacco leaves are usually packed in sacks and then transported to a designated location by truck. Existing sacks are usually filled with tobacco manually, which requires one hand to open the mouth of the sack, and then use the other hand to grab the tobacco leaves and put them into the sack. After the sack is full, the mouth of the sack is sealed by sewing. This method of loading tobacco is inefficient, especially when sewing tobacco bags, because the mouth of the sack is in an open state after the tobacco is loaded, and the sewing requires the cooperation of two people, one of whom assists in closing the mouth of the sack, and the other sews. When performing large-scale tobacco loading operations, the manpower and time costs invested are high, the operation is time-consuming, labor-intensive and inefficient. Therefore, it is a technical problem that needs to be solved urgently to design a clamping device suitable for sewing tobacco bags to replace manual operations. Utility Model Content

[0022] 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 some embodiments of the utility model, not all embodiments. Based on the embodiments of 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.

[0023] Example 1

[0024] like Figure 1-2 As shown, a clamping device suitable for sewing cigarette packages includes a sack opening and closing structure 1, which can be opened into a ring shape that matches the sack mouth or closed to form a straight shape, and a plurality of sack clamping mechanisms 2 are arranged on the sack opening and closing structure 1.

[0025] When in use, the sack opening and closing structure 1 can be opened into a ring shape, and the sack can be clamped and fixed on the sack opening and closing structure 1 through the sack clamping mechanism 2, and the sack mouth can be opened. The sack clamping mechanism 2 can be held by hand to load cigarettes. After the cigarettes are loaded, the sack opening and closing structure 1 can be brought together to form a straight line, and then the sack mouth can be closed, and the sack mouth can be sewn, which is easy to operate.

[0026] The sack opening and closing structure 1 is formed by splicing a plurality of aluminum profiles 101 , and adjacent aluminum profiles 101 can be connected to each other via a hinge structure 102 , and a limiting mechanism is provided on the aluminum profile 101 to prevent the sack opening and closing structure 1 from closing together to form a straight line and then opening.

[0027] The limiting mechanism comprises at least two pieces symmetrically arranged on both sides of the sack opening and closing structure 1, which can ensure that the limiting is more reliable.

[0028] The limiting mechanism includes a magnetic structure 103 arranged on opposite sides of two relatively positioned aluminum profiles 101. When the sack opening and closing structure 1 is brought together to form a straight line, the magnetic structure 103 can prevent the sack opening and closing structure 1 from opening.

[0029] Alternatively, the limiting mechanism includes a hook 104, and the hook 104 is rotatably connected to the aluminum profile 101 through a hinge structure 105. When the sack opening and closing structure 1 is brought together to form a straight line, the hook 104 is rotated to snap onto the aluminum profile opposite to it, so as to prevent the sack opening and closing structure 1 from opening. Specifically, an elongated round hole is provided on the hook 104, so that the hook 104 is connected to the hinge structure 105 through an adjusting screw, and the installation distance of the hook 104 can be adjusted through the elongated round hole, so that the hook 104 is more convenient to snap onto the aluminum profile opposite to it.

[0030] The sack clamping mechanism 2 is any clamp that can clamp the mouth of the sack, such as an elastic clamp, a grasping clamp, a hook, etc.

[0031] Example 2

[0032] like Figure 3 As shown, based on Example 1, the clamping device also includes a supporting frame 3, the sack opening and closing structure 1 is fixed on the top of the supporting frame 3, and an automatic adjustment structure 4 for controlling the opening or closing of the sack opening and closing structure 1 is provided on one side of the sack opening and closing structure 1.

[0033] The support frame 3 includes a rectangular frame 301 formed by splicing cross bars, and support vertical bars 302 are provided at the four corners of the bottom of the rectangular frame 301, and an enlarged support foot 303 is provided at the bottom of the support vertical bars 302. A fixed rod 304 fixedly connected to the support vertical bars 302 is provided on one side below the rectangular frame 301, and a movable rod 305 is provided on the other side, and the movable rod 305 is connected to the fixed rod 304 through an automatic adjustment structure 4. One side of the gunny sack opening and closing structure 1 is fixed on the fixed rod 304, and the other side is connected to the movable rod 305. When in use, the automatic adjustment structure 4 drives the movable rod 305 away from the fixed rod 304, so that the gunny sack opening and closing structure 1 can be automatically unfolded. On the contrary, the automatic adjustment structure 4 drives the movable rod 305 close to the fixed rod 304, so that the gunny sack opening and closing structure 1 is automatically closed. Specifically, the gunny sack opening and closing structure 1 can be connected to the fixed rod 304 and the movable rod 305 through a connecting plate 5 with bolts, which is convenient for disassembly and replacement.

[0034] The automatic adjustment structure 4 can be an electric telescopic rod structure or a screw transmission mechanism. The automatic adjustment structure 4 is two pieces symmetrically arranged at both ends of the fixed rod 304, which can not only avoid interference with cigarette loading, but also facilitate the stable opening or closing of the sack opening and closing structure 1.

[0035] The above is only a preferred embodiment of the utility model, and does not limit the confidentiality of the utility model in any form. Any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still falls within the scope of the technical solution of the utility model.
