Description

Technical Field

[0001] The utility model relates to the technical field of wine box printing, in particular to a printing device for processing paper wine boxes. Background Art

[0002] A wine box is an outer packaging for wine. The sides of the wine box are usually printed with colorful patterns and texts. Therefore, printing equipment is needed to print on its surface.

[0003] The prior art wine box printing equipment generally includes a printing roller, a cleaning mechanism and a drying component arranged on a printing platform. The cleaning mechanism includes a rotating disk with a soft brush, and the dust on the surface of the wine box is cleaned by the soft brush of the rotating disk. The drying component dries the surface of the wine box after printing by the printing roller. However, the soft brush of the rotating disk of the prior art rotates at a high speed driven by the motor and the transmission rod, which is easy to cause wear on the surface of the wine box. Especially when the surface of the wine box is stained with oily solid particles, the high-speed rotating soft brush will aggravate the friction between the solid particles and the surface of the wine box, causing wear; and the hot air blower of the drying component is fixedly arranged, and cannot evenly dry the surface of the wine box after printing. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a printing device for processing paper wine boxes.

[0005] The technical solution of this utility model is as follows:

[0006] A printing device for processing paper wine boxes, comprising a printing platform with a conveyor belt, a support frame is arranged above the conveyor belt, a blower mechanism and a printing mechanism are arranged on the support frame, and the blower mechanism is located between the conveyor belt and the printing mechanism;

[0007] The air blowing mechanism includes an air collecting box and an air supply device connected to the air collecting box. The length direction of the air collecting box is perpendicular to the conveying direction of the conveyor belt. Both ends of the air collecting box are slidably connected to the inner side of the support frame and can reciprocate along the conveying direction of the conveyor belt. A blowing member is provided under the air collecting box, and the blowing port of the blowing member faces the conveyor belt.

[0008] The printing mechanism comprises a printing liquid tank and a printing nozzle which are connected to each other, and the printing nozzle is arranged toward the conveyor belt.

[0009] The conveyor belt is used to transport paper wine boxes to be printed. The wind collecting box is arranged above the conveyor belt, and is used to blow gas to the paper wine boxes on the conveyor belt to blow away dust and solid particles on the surface of the paper wine boxes, thereby reducing wear and damage to the surface of the paper wine boxes. The blown paper wine boxes are moved to the printing mechanism for printing under the conveyor belt. After printing is completed, the paper wine boxes are evenly air-dried by the wind collecting box that can move along the conveying direction of the conveyor belt.

[0010] The specific structure of the above-mentioned air collecting box that can move on the support frame is that the support frame is a door-shaped structure with two opposite side panels, a single side panel is provided with a first lead screw, one end of the first lead screw is provided with a driving motor for its rotation, the length direction of the first lead screw is perpendicular to the length direction of the air collecting box, and the end of the air collecting box is threadedly connected to the first lead screw.

[0011] Regarding the specific structure of the blowing part, the blowing part includes several first nozzles arranged along the length direction of the air collecting box. The nozzle of the first nozzle cannot be perpendicular or parallel to the upper surface of the conveyor belt, and is not in the same direction as the conveying direction of the conveyor belt. The first nozzle has an angle with the upper surface of the conveyor belt and is facing the starting end of the conveyor belt, which is used to blow the dust and solid particles on the surface of the paper wine box to the outside of the printing platform.

[0012] In order to facilitate the blowing part to dry the printed paper wine box, the blowing part also includes several second nozzles arranged along the length direction of the air collecting box. The second nozzle is arranged side by side with the first nozzle, and the nozzle of the second nozzle is perpendicular to the upper surface of the conveyor belt. After the paper wine box is printed, the air collecting box drives the second nozzle to move toward the printing position of the paper wine box, and the pigment of the paper wine box can be better dried through the vertically arranged nozzles.

[0013] In order to improve the drying effect of the printed paper wine box, an electric heating wire and its power supply are arranged in the air collecting box. After the electric heating wire is heated, hot air is delivered to the surface of the paper wine box through the blowing part.

[0014] Regarding the setting position of the electric heating wire, the air collecting box is connected to the air supply device through an air duct, one end of the air duct is connected to the end of the air collecting box, and the electric heating wire is set close to the air duct to facilitate faster delivery of the instantly heated air through the blowing member.

[0015] The position of the existing printing nozzle is fixed, and both sides of the paper wine box cannot be fully printed. The printing mechanism also includes a transverse movement component, which includes a ball screw. The axial direction of the ball screw is perpendicular to the conveying direction of the transmission belt. The ball screw has a nut. The printing nozzle is set on the nut and can move in a straight line. The ball screw can drive the printing nozzle to move back and forth along the width direction of the conveyor belt, which is convenient for printing in all directions.

[0016] The specific structure of the printing nozzle being able to move in a straight line direction is that the ball screw is rotatably arranged between the two side plates, and a guide rod parallel to the ball screw is also arranged between the two side plates, and the guide rod is penetrated in the connecting seat and slidably connected with the connecting seat.

[0017] Regarding the specific structure of the printing nozzle, the printing nozzle includes a connecting seat and a nozzle. The printing liquid tank and the nozzle are connected through a material pipe. The material pipe passes through the connecting seat. The connecting seat is installed on a nut. The connecting seat follows the nut to move on the ball screw.

[0018] In order to facilitate the wind collecting box to blow away the soot and dry the paper wine box through the nozzle, the nozzle is arranged to be able to move up and down so that the wind collecting box does not interfere with the nozzle when moving. The nozzle is connected to the connecting seat through a telescopic mechanism. The highest point that the nozzle can reach is higher than the wind collecting box, and the lowest point that it can reach is lower than the wind collecting box.

[0019] The beneficial effects of the utility model are:

[0020] The dust and solid particles on the surface of the paper wine box are cleaned by the first nozzle under the air collecting box. Compared with the prior art method in which the bristles are in direct contact with the surface of the paper wine box, the wear on the surface of the paper wine box can be reduced, and the dust and solid particles can also be cleaned by air blowing;

[0021] The printing nozzle that can move up and down and left and right is convenient for printing on the edges of paper wine boxes that are difficult to print, thus improving the printing effect;

[0022] A heating wire is arranged in the air collecting box, and air heated by the heating wire is blown to the surface of the printed paper wine box through the first nozzle and the second nozzle, so as to achieve a drying effect on the surface of the paper wine box.

[0033] See also Figure 1 , Figure 3 and Figure 4 A printing device for processing paper wine boxes shown in the figure includes a printing platform 1 with a conveyor belt 2, the upper conveying surface of the conveyor belt 2 is flush with the upper end surface of the printing platform 1, and a support frame 3 is provided on the printing platform 1. The support frame 3 is a door-shaped structure with two symmetrically arranged side panels 31. The lower ends of the two side panels 31 are installed on both sides of the printing platform 1 and are located on the outside of the width direction of the conveyor belt 2. The upper ends of the two side panels 31 are connected by a top plate 32. The support frame 3 is located above the conveyor belt 2. A blower mechanism and a printing mechanism are provided on the support frame 3. The blower mechanism is located between the conveyor belt 2 and the printing mechanism.

[0034] Among them, the blowing mechanism includes an air collecting box 4 and an air supply device 5 connected to the air collecting box 4. The air collecting box 4 is a long box with a cavity. The length direction of the air collecting box 4 is perpendicular to the conveying direction of the conveyor belt 2. The two ends of the air collecting box 4 are solid structures, and the two ends are slidably connected to the inner side of the support frame 3 and can move back and forth along the conveying direction of the conveyor belt 2. A blowing piece is provided under the air collecting box 4, and the blowing port of the blowing piece faces the conveyor belt 2.

[0035] See also Figure 2 As shown, the specific structure of the air collecting box 4 being able to move on the support frame 3 is that the opposite surfaces of the two side plates 31 are provided with sliding grooves 33, the sliding grooves 33 are horizontally arranged, and the length direction is the same as the conveying direction of the conveyor belt 2, the two sliding grooves 33 are symmetrically arranged, and a first screw 10 is arranged in each sliding groove 33, one end of the first screw 10 is rotatably connected in the sliding groove 33, and the other end extends out of the side plate 31 and is connected to the drive motor 11, and the length direction of the first screw 10 is perpendicular to the length direction of the air collecting box 4. The end portion is threadedly connected to the first lead screw 10, and each side panel 31 is provided with a first lead screw 10 and a driving motor 11 connected thereto. By controlling the two first lead screws 10 to rotate synchronously, the two ends of the air collecting box 4 can be driven to move synchronously in the horizontal direction, so that the blowing member under the air collecting box 4 can move along the conveying direction of the conveyor belt 2, and the dust on the surface of the wine box to be printed on the conveyor belt 2 is cleaned. The moving direction of the air collecting box 4 can be opposite to the conveying direction of the conveyor belt 2, so that dust and solid particles will not enter the printing area.

[0036] See also Figure 5 and Figure 6 As shown, the specific structure of the blowing member is that the blowing member includes several first nozzles 12 arranged along the length direction of the air collecting box 4 and several second nozzles 13 arranged along the length direction of the air collecting box 4, and the second nozzle 13 is arranged side by side with the first nozzle 12. The nozzle of the first nozzle 12 cannot be perpendicular or parallel to the upper surface of the conveyor belt 2, and is not in the same direction as the conveying direction of the conveyor belt 2. The first nozzle 12 has an angle with the upper surface of the conveyor belt 2 and is oriented toward the starting end of the conveyor belt 2, which is used to blow the dust and solid particles on the surface of the paper wine box to the outside of the printing platform 1. The second nozzle 13 is set to facilitate the blowing member to dry the printed paper wine box. The nozzle of the second nozzle 13 is perpendicular to the upper surface of the conveyor belt 2. After the paper wine box is printed, the air collecting box 4 drives the second nozzle 13 to move to the printing position of the paper wine box, and the vertically arranged nozzle 82 is used to better dry the pigment of the paper wine box.

[0037] See also Figure 7 As shown, the wind sent into the air collecting box 4 by the air supply device 5 is air at normal temperature. The air supply device 5 can be a hot air blower for blowing hot air with temperature. However, there is a long air duct 6 between the air supply device 5 and the air collecting box 4. The temperature of the hot air with temperature will be greatly reduced after passing through the long air duct 6, and the drying effect on the printed surface of the paper wine box is poor. In order to reduce the heat loss and improve the drying effect on the paper wine box after printing, an electric heating wire 14 and its power supply are provided in the air collecting box 4. The power supply is the prior art and is no longer shown in the figure. The power supply can be set on the outside of the air collecting box 4 to avoid damage to the power supply due to the high temperature in the air collecting box 4. After the electric heating wire 14 is heated, the hot air is transported to the surface of the paper wine box through the blowing member. Regarding the setting position of the electric heating wire 14, the air collecting box 4 is connected to the air supply device 5 through the air duct 6, and one end of the air duct 6 is connected to the end of the air collecting box 4. The electric heating wire 14 is arranged close to the air duct 6, which is convenient for quickly transporting the instantly heated air out through the blowing member. The air collecting box 4 has a short-term heat preservation effect on the heat generated by the electric heating wire 14. Driven by the wind delivered by the air supply device 5, the generated heat can be blown to the paper wine box on the conveyor belt 2 in a short time, reducing heat loss and improving the drying effect on the printed surface of the paper wine box.

[0038] The beneficial effects achieved by the above structure are as follows: dust and solid particles on the surface of the paper wine box are cleaned through the first nozzle 12 under the air collecting box 4. Compared with the prior art method of directly contacting the surface of the paper wine box with the bristles, the wear on the surface of the paper wine box can be reduced, and the dust and solid particles can also be cleaned by air blowing; by arranging a heating wire in the air collecting box 4, the air heated by the heating wire is blown to the surface of the printed paper wine box through the first nozzle 12 and the second nozzle 13, which has a drying effect on the surface of the paper wine box.

[0039] See also Figure 3 and Figure 4 As shown, the printing mechanism includes a printing liquid tank 7 and a printing nozzle 8 which are connected. The printing liquid tank 7 is arranged on the top plate 32. The printing nozzle 8 includes a connecting seat 81 and a nozzle 82. The nozzle 82 is a prior art and can spray the pigment in the printing liquid tank 7. The printing liquid tank 7 and the nozzle 82 are connected through a material pipe 9. The material pipe 9 passes through the connecting seat 81. The printing nozzle 8 is arranged toward the conveyor belt 2. The position of the existing printing nozzle 8 is fixed, and both sides of the paper wine box cannot be fully printed. The printing mechanism also includes a transverse movement component. The transverse movement component includes a ball screw 15. The axial direction of the ball screw 15 is perpendicular to the conveying direction of the transmission belt. The ball screw 15 has a nut. The nut is rotatably connected to the ball screw 15. This is a prior art and is not shown in the figure. One end of the ball screw 15 is rotatably connected to the side plate 31, and the other end passes through the other side plate 31 and is connected to the screw motor 16 on the outside of the support frame 3. A nut is provided on the ball screw 15, and the ball screw 15 drives the nut to move. This is a prior art. Without further elaboration, the connecting seat 81 of the printing head 8 is set on the nut, and the ball screw 15 is rotatably set between the two side plates 31. A guide rod 17 parallel to the ball screw 15 is also provided between the two side plates 31. The guide rod 17 is set below the ball screw 15, and the guide rod 17 is passed through the connecting seat 81 and slidably connected with it. The guide rod 17 plays a guiding role to prevent the connecting seat 81 from rotating during movement, so that the connecting seat 81 can move in a straight line along the width direction of the conveyor belt 2, and the ball screw 15 can drive the printing head 8 to move back and forth along the width direction of the conveyor belt 2, so as to facilitate printing in all directions.

[0040] See also Figure 3 and Figure 4 As shown, in order to facilitate the air collecting box 4 to blow away and dry the paper wine box through the nozzle 82, the nozzle 82 is arranged to be able to move up and down, so that the air collecting box 4 does not interfere with the nozzle 82 when moving, and the nozzle 82 is connected to the connecting seat 81 through the telescopic mechanism 18. The telescopic mechanism 18 can be a small electric push rod or a cylinder. The telescopic mechanism 18 is vertically arranged, and the output rod of the telescopic mechanism 18 is fixedly connected to the bottom of the connecting seat 81. The shell of the telescopic mechanism 18 is connected to the shell of the nozzle 82. The output rod of the telescopic mechanism 18 is extended to drive the nozzle 82 to move downward. The lowest point that the nozzle 82 can reach is lower than the air collecting box 4, and the paper wine box on the conveyor belt 2 can be printed. The output rod of the telescopic mechanism 18 is retracted to the minimum stroke, which can drive the nozzle 82 to a position higher than the air collecting box 4, without hindering the movement of the air collecting box 4, so that the air collecting box 4 can clean the surface of the paper wine box before printing and dry its surface after printing.
