Description

Technical Field

[0001] The utility model relates to the field of commodity packaging equipment, in particular to a limiting device for inkjet coding and transmission of packaging bags. Background Art

[0002] When an inkjet printer is used to inkjet code a packaging bag, the packaging bags to be inkjet coded are stacked and placed at the feeding port. The feeding clamp of the filling machine will continuously pick up single packaging bags through a rotating mechanism and rotate them into the air, and then the inkjet conveying clamp at the lower end of the transportation track will pick up the packaging bags hovering in the air, pass them through the inkjet printer for inkjet coding, and then send them to the discharging port. When the feeding clamp picks up the packaging bag and hovers in the air, because the packaging bag is soft in texture, the problem of upturned feet will occur, and it cannot be ensured that the packaging bag hovers vertically in the air completely. In this way, when the upturned-foot packaging bag passes through the inkjet printer for inkjet coding, the inkjet position cannot be guaranteed to be at the same horizontal position, resulting in problems such as unclear, skewed, and uneven character display size of the sprayed information on the inkjet-coded packaging bag, affecting production efficiency, increasing the rejection rate, and raising production costs. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a limiting device for inkjet coding and transmission of packaging bags, so that the packaging bag always remains vertical during the inkjet coding and transmission process, and the spraying effect is improved.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is: a limiting device for inkjet coding and transmission of packaging bags, including a feeding clamp that clamps the packaging bag from the feeding port to the air. A vertical backboard is arranged below the feeding clamp. A transportation track is arranged above the right side of the vertical backboard. An inkjet conveying clamp is arranged on the transportation track. A compressed air tank for blowing the packaging bag to fit the vertical backboard is arranged on the left side of the vertical backboard. The air outlet pipe led out from the compressed air tank points to the vertical backboard. A limiting plate with a wide inlet and a narrow outlet and the installation direction consistent with the transportation direction of the transportation track is arranged at the right edge of the vertical backboard, and an inkjet port is opened on the limiting plate.

[0005] The further improvement of the technical solution of the utility model lies in that: the limiting plate includes a rear straight plate and a front curved plate, and the rear straight plate and the front curved plate are connected and fixed through a connecting bottom plate with a front-wide and rear-narrow and curved contraction at the bottom. The contraction curve of the connecting bottom plate is consistent with the curve of the front curved plate.

[0006] The further improvement of the technical solution of the utility model lies in that: a rectangular inkjet port with a hollow right side is opened on the front curved plate.

[0007] The further improvement of the technical solution of the utility model lies in that: long strip-shaped vertical through holes are arranged on the rear straight plate, and long strip-shaped vertical through holes are also arranged on the vertical backboard. The vertical through holes are installed and connected through a plurality of bolts. The rear straight plate is installed on the rear surface of the vertical backboard. Sinking grooves for making the bolt heads flush with the front surface are arranged around the vertical through holes on the front surface of the vertical backboard.

[0008] A further improvement of the technical solution of the utility model is that a code avoidance opening corresponding to the code injection opening is provided on the rear straight plate.

[0009] A further improvement of the technical solution of the utility model is that a pipe clamp for controlling and adjusting the direction of the outlet pipe opening is arranged on the left side of the vertical back plate.

[0010] Due to the adoption of the above-mentioned technical solution, the technical progress achieved by the utility model is as follows: by setting a compressed air tank, the compressed air sprayed from the air outlet pipe can be blown to the surface of the suspended packaging bag, so that the packaging bag is attached to the back plate and remains vertical, and the subsequent printed words will not be skewed or unclear. By setting a wide-in and narrow-out limit plate, the suspended packaging bag can be further limited in cooperation with compressed air to ensure the vertical position during spraying. By setting the front plate of the limit plate as a curved plate, the transition is more natural and the limiting effect is good. By setting a long vertical through hole and fixing it with bolts, the position of the limit plate can be adjusted up and down more flexibly to target different types of packaging bags.

[0015] The present invention is further described in detail below in conjunction with the embodiments:

[0016] like Figure 1As shown in the figure, it is a schematic structural diagram of a limit device for inkjet coding and transmission of packaging bags. When performing inkjet coding operations on packaging bags, the packaging bags 7 to be inkjet coded are stacked and placed at the feeding port, waiting for inkjet coding. The feeding clamp 2 of the filling machine continuously picks up single packaging bags 7 from the feeding port and hovers them in mid-air. A vertical backboard 1 is arranged below the feeding clamp 2. A transportation track 3 is arranged above the right side of the vertical backboard 1. An inkjet coding conveying clamp 4 is arranged on the transportation track 3, which is used to pick up the packaging bags 7 from the feeding clamp 2 and transport them to the inkjet coding machine through the track for inkjet coding. After inkjet coding, the packaging bags 7 after inkjet coding are sent into the discharge port. A compressed air tank 6 is arranged on the left side of the vertical backboard 1. An air outlet pipe is led out from the compressed air tank 6. A pipe clamp for controlling and adjusting the direction of the air outlet pipe orifice is arranged on the left side of the vertical backboard 1. The air outlet pipe orifice is clamped by the pipe clamp and the direction is adjusted so that the air outlet pipe orifice points obliquely downward towards the vertical backboard 1, and the compressed air blown out from the orifice blows towards the outer surface of the hovering packaging bag 7, hitting the packaging bag towards the vertical backboard 1, so that the suspended packaging bag 7 fits against the vertical backboard to maintain an initial vertical state and eliminate the phenomenon of warping feet. A limiting plate 5 with a wide inlet and a narrow outlet and the installation direction consistent with the transportation direction of the transportation track 3 is arranged at the right edge of the vertical backboard 1. A coding port 54 is opened on the limiting plate 5.

[0017] The structure of the limiting plate 5 is as Figure 2As shown, it is composed of three plates connected, including a rear straight plate 51 and a front curved plate 53 that bends forward. The rear straight plate 51 and the front curved plate 53 are connected and fixed by a connecting bottom plate 52 whose bottom is wide at the front and narrow at the back, and the curvature of the connecting bottom plate 52 is consistent with the curvature of the front curved plate 53, and is tightly connected. A rectangular inkjet port 54 with a hollow right side is provided on the front curved plate 53, which is used to face the inkjet printer. The inkjet printer can print the three-phase information to be sprayed on the packaging bag 7 through this inkjet port 54, ensuring the stability of the inkjet printing, clear handwriting and fixed position. A long vertical through hole is provided on the rear straight plate 51, and a long vertical through hole of the same size is also provided below the right edge of the vertical back plate. The vertical through holes of the rear straight plate 51 and the vertical back plate 1 are aligned, and the installation connection between the two plates is achieved by simultaneously passing a number of bolts through the two through holes and tightening them to fix them. When fixing, the upper and lower relationship of the two vertical through holes can be adjusted, and then the installation position of the limit plate 5 can be adjusted to cope with packaging bags of different sizes, so as to be suitable for 1kg packaging bags and 500g packaging bags, and have wider applicability. The rear straight plate 51 is installed on the rear surface of the vertical back plate 1. The bolts are screwed in from the front surface of the vertical back plate 1. In order to ensure the flatness of the front surface of the vertical back plate 1, a sink groove is dug around the vertical through hole on the front surface. The head of the screwed-in bolt can be tightened and fixed while sinking into the sink groove and flush with the front surface. The bolt head will not protrude, ensuring the flatness of the front surface and making the packaging bag fit better. The rear straight plate 51 is provided with a code avoidance port that is opposite to the coding port 54 of the front curved plate 53 and has the same shape to ensure that when the coding conveying clamp 4 fails to clamp the packaging bag 7, the inkjet printer will not spray on the limit plate 5 when performing empty spraying, thereby extending the service life of the limit plate 5.

[0018] When the present invention is used to limit the packaging bag during the coding transmission process, when the feeding clamp clamps the packaging bag and suspends it in the air, compressed air will blow to the surface of the packaging bag to ensure that the packaging bag is in close contact with the vertical back plate 1, so that the packaging bag is vertically positioned in the air and the curling phenomenon is effectively eliminated. The coding conveying clamp 4 clamps the packaging bag and enters from the wide entrance of the limiting plate, which becomes narrower and can eliminate the curling phenomenon again until it is completely limited at the narrow exit. The inkjet printer sprays information on the limited and clamped packaging bag from the coding port to ensure that the sprayed information is clear and the position is flat.

[0019] The embodiments described above are merely descriptions of preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
