Description

Technical Field

[0001] The utility model relates to a packaging box conveying line, in particular to a conveying line which can improve the coding quality of an outer packaging box of an ointment. Background Art

[0002] After the production and packaging of ointment drugs, three phases (i.e., the production date, product batch number, and expiration date) need to be printed on the outer packaging carton. The existing technology has two problems: 1) When a roller conveyor line is used for transportation, there are slight bumps during the transportation of the outer packaging box, resulting in blurred coding and waves; 2) When the packaging equipment fails, the coding is not continuous. When the interval between two coding is long (such as about 20 minutes), the ink in the coding equipment is easy to solidify, resulting in poor printing effect. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a conveyor line that can improve the quality of inkjet coding of outer packaging boxes of ointments, on the one hand to avoid blurred inkjet coding due to bumps during transportation of the outer packaging boxes; on the other hand to avoid the problem of poor inkjet coding effect due to long time intervals.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A conveyor line that can improve the inkjet coding quality of outer packaging boxes of ointments includes a first roller conveyor line and a second roller conveyor line. The first roller conveyor line and the second roller conveyor line are arranged vertically and a push rod is arranged at the end of the first roller conveyor line. The lower end of the push rod is connected to the cylinder. The push rod pushes the outer packaging box from the first roller conveyor line to the second roller conveyor line. The roller of the second roller conveyor line is covered with a belt, the lower end of the belt is tensioned by a tensioning roller, and the tension is adjusted at both ends of the tensioning roller by a tensioning mechanism.

[0006] Detection probes are installed at the input ends of the first roller conveyor line and the second roller conveyor line.

[0007] An end baffle is provided at the end of the first roller conveyor line, and a side baffle is provided at one side of the second roller conveyor line, and the end surfaces of the end baffle and the side baffle are flush.

[0008] The utility model provides a conveyor line that can improve the quality of inkjet coding of ointment outer packaging boxes, and has the following technical effects:

[0009] 1) If the nozzle of the coding equipment is interrupted for too long after spraying, the liquid ink in the nozzle will be initially condensed, resulting in blockage and unqualified words. By using two sets of detection probes, when one set of detection probes detects that an outer packaging box passes through the first roller conveyor line, pre-spraying can be completed to spray out the blockage in the coding equipment and clean the inside of the nozzle. In this way, when the outer packaging box moves from the first roller conveyor line to the second roller conveyor line, the other set of detection probes detects, and the nozzle of the coding equipment sprays again, and effective coding can be completed this time.

[0010] 2) Set up a belt on the second roller conveyor line and tighten it so that the outer packaging box moves steadily and at a uniform speed, the coding process is stable, and the font is straight. Avoid blurry coding. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] like Figure 1-2As shown, a conveyor line that can improve the quality of inkjet printing of outer packaging boxes of ointments includes a first roller conveyor line 1 and a second roller conveyor line 2. The first roller conveyor line 1 and the second roller conveyor line 2 both include a frame, a leg is arranged at the lower end of the frame, and a plurality of rollers 12 are rotatably installed on the upper end of the frame along the length direction. A pair of sprockets are arranged on one side of each roller 12, and a chain is wound around the sprockets between adjacent rollers 12. The sprocket of one roller 12 is driven by a motor and a first chain transmission mechanism. When the motor is started, all the rollers 12 of the first roller conveyor line 1 rotate synchronously, and all the rollers 12 of the second roller conveyor line 2 rotate synchronously. In this way, the outer packaging box falling thereon will also move accordingly. The first roller conveyor line 1 and the second roller conveyor line 2 are arranged vertically, and the input end of the first roller conveyor line 1 is transitionally connected with the output end of the packaging equipment, and the output end of the first roller conveyor line 1 is vertically opposite to the input end of the second roller conveyor line 2. Space can be saved by vertical arrangement. A push rod 3 is arranged above the end of the first roller conveyor line 1, and a connecting rod is fixed at the lower end of the push rod 3. The connecting rod extends downward from the roller 12 and is connected to the cylinder 4 arranged at the bottom. When the cylinder 4 contracts, the push rod 3 can push the outer packaging box from the first roller conveyor line 1 to the second roller conveyor line 2. The roller 12 of the second roller conveyor line 2 is covered with a belt 5, and the lower end of the belt 5 is tensioned by a tensioning roller 6. The tensioning force of the two ends of the tensioning roller 6 is adjusted by a tensioning mechanism 7. When the roller 12 rotates, the belt 5 is transported along with the rotation of the roller 12.

[0018] like Figure 1 As shown, the input ends of the first roller conveyor line 1 and the second roller conveyor line 2 are both equipped with detection probes 8. The detection probes 8 can be infrared sensors or photoelectric switches, etc., for detecting that the outer packaging box reaches the corresponding position.

[0019] like Figure 1 As shown, an end baffle 9 is provided at the end of the first roller conveyor line 1, and a side baffle 10 is provided on one side of the second roller conveyor line 2, and the end surfaces of the end baffle 9 and the side baffle 10 are flush. The end baffle 9 limits the position of the end of the first roller conveyor line 1 for conveying the outer packaging box, and at the same time, the outer packaging box contacts the side baffle 10 when it moves to the second roller conveyor line 2. The side baffle 10 guides and positions the outer packaging box for conveying forward, so that the side baffle 10 and the inkjet device on the inkjet device mounting frame 11 are kept at a certain distance, and the outer packaging box is conveyed forward closely against the side baffle 10 on the second roller conveyor line 2, and the inkjet device is extended and retracted later to realize inkjet.

[0020] like Figure 4As shown, the tensioning mechanism 7 includes left and right screw rods 7.1, which are fixed on both sides of the frame of the second roller conveyor line 2. A compression spring 7.2 is sleeved on the screw rod 7.1, and the upper semicircular clamp 7.3 and the lower semicircular clamp 7.4 pass through the left and right screw rods 7.1 and the lower ends are limited by nuts 7.5. The limiting ring between the upper semicircular clamp 7.3 and the lower semicircular clamp 7.4 can clamp the outer ring of the bearing at the end of the tensioning roller 6, and the inner ring of the bearing is fixedly connected to the tensioning roller 6. In this way, the installation of the tensioning roller 6 can be realized and the tensioning roller 6 can be ensured to be rotatable. Since the installed compression spring 7.2 is in a compressed state, under the gravity of the tensioning roller 6 and the elastic force of the compression spring 7.2, the tensioning roller 6 maintains a downward force and can tension the belt 5.

[0021] Working principle and process:

[0022] 1) Since the belt 5 is tightly wrapped around the roller 12, when the roller 12 is driven to rotate, the belt 5 realizes transmission and conveys the outer packaging box forward. Since the upper half of the belt 5 is horizontal and supported by the roller 12, the outer packaging box will not be bumpy when moving, and blur can be avoided when spraying the code.

[0023] 2) When the outer packaging box moves to the input end of the first roller conveyor line 1, the detection probe 8 there detects, and the control box controls the inkjet printer to perform a pre-spray (empty spray) once to spray out the ink that may solidify inside to clean the inside; when the outer packaging box moves to the output end of the first roller conveyor line 1, the cylinder 4 contracts, and the push rod 3 pushes the outer packaging box to the belt of the second roller conveyor line 2, and the belt transports the outer packaging box. When the carton passes through the inkjet printer, the detection probe 8 there detects a signal, and the control box controls the inkjet printer to print again to achieve normal inkjet printing.
