Description

Technical Field

[0001] The invention belongs to the technical field of tobacco production, and in particular relates to a top supporting device for a positioning mechanism of a box-type leaf storage and packing machine. Background Art

[0002] Box-type tobacco storage is a key process in the production line's fine-quality tobacco production line. Its function is to box tobacco leaves after loading them. After a certain period of storage to meet the tobacco production process standards, they are shipped out for shredding. Box-type tobacco storage consists of two modules: empty box loading and filled box shipping. The empty box loading module transports empty boxes from the material conveyor roller conveyor to the loading position. After positioning, a robot removes the box lid, fills the box with tobacco leaves, and replaces the lid before returning it to the warehouse for storage.

[0003] like Figure 1 As shown, when the empty box body 12 enters the packing position through the chain conveyor 11, the position information of the cigarette box is confirmed by the photoelectric switches 13 installed on both sides of the logistics conveying roller, and the position of the cigarette box is confirmed by the positioning mechanism. When the box body is transported to the photoelectric switch detection position, the logistics conveying roller motor stops running, and at the same time the cylinder in the positioning mechanism is actuated, and the cylinder piston rod extends, so that the positioning roller assembly 14 installed on the end of the piston rod blocks the box body, thereby playing the role of positioning the box body. Among them, a sliding guide rail and a slider that slides with the sliding guide rail are provided on the cylinder fixing plate, the positioning roller assembly is provided on the slider, and the end of the piston rod is connected to the slider. The cylinder drives the slider to reciprocate on the sliding guide rail through the piston rod; Figure 1 The arrows in the figure indicate the direction of logistics transportation.

[0004] After the logistics conveying roller motor stops running, the box will move forward a certain distance in the logistics conveying direction due to the influence of inertia. At this time, a lateral impact force will be generated on the positioning roller assembly, and the impact force will be transmitted to the sliding guide rail fixing screws through the slider and the sliding guide rail. After long-term use, the positioning roller assembly will be frequently subjected to lateral impact forces, which will make the sliding guide rail fixing screws easy to break, thereby causing the positioning mechanism to shift and the box positioning to be inaccurate. If it is not discovered in time, the cylinder and magnetic switch will be damaged, and eventually the equipment will fail and shut down, affecting the equipment operation efficiency. Summary of the Invention

One side of the fixed block 31 is connected to one side of the sliding guide rail on the mounting frame close to the positioning mechanism, and the other side of the fixed block is provided with a U-shaped groove, and the opening 32 of the U-shaped groove faces the sliding guide rail; a first fixed shaft is provided in the U-shaped groove, and the center hole of the first pulley is rotatably engaged with the first fixed shaft, and the two ends of the first fixed shaft are respectively connected to the two side plates of the U-shaped groove; the first pulley 41 has a protruding portion located outside the opening 32, and the outer circumferential surface of the protruding portion is used for rolling engagement with the slider of the positioning mechanism, and the mounting frame is arranged on the right side of the positioning mechanism.

[0030] The embodiment of the present invention provides a supporting device for the positioning mechanism of a box-type leaf storage cartoner, wherein the first pulley has a protruding portion located outside the opening 32 of the U-shaped groove, and the outer circumferential surface of the protruding portion can roll with the slider of the positioning mechanism, thereby not affecting the reciprocating motion of the slider on the sliding guide rail, nor affecting the function of the positioning mechanism; at the same time, the mounting frame is arranged on the right side of the positioning mechanism, and since the lateral impact force acts on the left side of the positioning mechanism, when the positioning roller assembly is subjected to a lateral impact force, since the slider contacts the first pulley 41, the supporting device can better block the slider, thereby preventing the slider from shifting laterally, that is, to the right, thereby better preventing the sliding guide rail fixing screws from breaking; and through the supporting device, the lateral impact force can be dispersed to the conveyor roller support frame through the mounting frame, thereby better alleviating the lateral impact force on the positioning mechanism, thereby greatly reducing the possibility of the sliding guide rail fixing screws breaking, enhancing the stability of the positioning mechanism, and effectively ensuring the operation efficiency of the cartoner.

[0031] Furthermore, the supporting device for the positioning mechanism of the box-type leaf storage packer provided in an embodiment of the present invention also includes a second pulley 51. A second fixed shaft parallel to the first fixed shaft is provided in the U-shaped groove. The center hole of the second pulley 51 is rotatably engaged with the second fixed shaft, and the two ends of the second fixed shaft are respectively connected to the two side plates of the U-shaped groove; the second pulley 51 has a protrusion located outside the opening, and the outer circumferential surface of the protrusion is used for rolling engagement with the slider of the positioning mechanism. With this solution, the first pulley and the second pulley are both in contact with the slider, so that when the positioning mechanism is subjected to a lateral impact force, the supporting device can play a better supporting role.

[0032] In one embodiment of the present invention, the supporting device for the positioning mechanism of the box-type leaf storage packer further includes a first connecting plate 61 and a second connecting plate 62 parallel to the first connecting plate.

This solution allows the first and second pulleys to be conveniently positioned in the U-shaped groove.

[0033] like Figure 3 As shown, the mounting frame is an L-shaped structure.

[0034] Furthermore, two mounting holes 23 are relatively provided on the transverse plate 21 of the mounting frame, so that the mounting frame and the conveyor roller support frame can be detachably connected through the mounting holes.

[0035] In order to ensure a firm and reliable connection between the fixing block and the mounting frame, the fixing block is welded to the vertical plate 22 of the mounting frame.

[0036] Furthermore, the two ends of the first fixed shaft are detachably connected to the two side plates of the U-shaped groove, so that the first pulley 41 and the first fixed shaft can be easily replaced and repaired. It is understood that the first pulley can preferably be a nylon wheel, so as to better buffer the lateral impact force.
