Technical Field

[0001] This utility model relates to the field of coating equipment technology, and more specifically, to a surface coating equipment for carton production. Background Technology

[0002] Carton lamination involves covering the surface of packaged goods with a thin film, which can improve the airtightness, moisture and water resistance, and pollution prevention of the packaged goods. For example, patent application number CN202011081462.2 describes a cardboard lamination device for cardboard processing, which includes a box body. The bottom of the box body is fixedly connected to a base, and the top of the box body is fixedly connected to a transport platform. A dust removal mechanism is provided on the left side of the top of the transport platform, and a flattening mechanism is provided on the right side of the transport platform. The dust removal mechanism includes a first support plate and a dust removal box. This invention relates to the field of cardboard lamination technology. This cardboard laminating device for cardboard processing incorporates a dust removal mechanism. A first motor drives a first rotating shaft, which, in conjunction with transmission gears, a transmission rack, a push rod, and a dust removal head, moves the dust removal brush up and down. A second motor drives the dust removal head to rotate. This allows for height adjustment based on cardboard thickness, preventing damage to the cardboard, and effectively cleaning particles, dust, and other impurities from the cardboard, thus avoiding air bubbles during lamination. After lamination, the film needs to be cut to separate the cardboard. When the film comes into contact with the cardboard, it undergoes elastic deformation without being positioned, pulling and deforming the film covering the cardboard. Utility Model Content

[0003] The main purpose of this utility model is to provide a surface coating equipment for carton production, which can effectively solve the problem in the background technology that after the coating is completed, the film needs to be cut to separate the cardboard. When the film comes into contact with the cardboard, it will undergo a certain elastic deformation without being positioned, which will pull and deform the film covering the cardboard.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a surface coating equipment for carton production, comprising a support platform, a first hydraulic cylinder fixedly mounted on the upper surface of the support platform, an installation frame mounted on the output end of the first hydraulic cylinder, a conveyor belt mounted between the inner walls of both sides of the installation frame, positioning rods fixedly mounted on both sides of the upper surface of the support platform, side plates fixedly mounted on the top ends of the two positioning rods, the two side plates slidably passing through the upper surface of the installation frame, a first electric pressure roller fixedly mounted between the two side plates, an installation shaft mounted between the top ends of the two side plates, and a positioning and cutting assembly provided on the installation frame.

[0005] Preferably, a guide roller is rotatably mounted between the two side plates, and the two guide rollers are disposed between the first electric pressure roller and the mounting shaft.

[0006] Preferably, a second electric pressure roller is rotatably mounted between one end of the two side plates.

[0007] Preferably, a fixing plate is installed on both sides of the upper end of the mounting bracket, and a second hydraulic cylinder is fixedly installed on each of the two fixing plates. A clamping plate is installed on the output end of each of the two second hydraulic cylinders.

[0008] Preferably, the positioning and cutting assembly includes two limiting plates, which are respectively fixedly installed on both sides of the upper surface of the mounting frame.

[0009] Preferably, a top plate is fixedly installed between the top ends of the two limiting plates, a third hydraulic cylinder is fixedly installed on the upper surface of the top plate, an mounting plate is installed on the output end of the third hydraulic cylinder, and a cutting blade is installed on the lower surface of the mounting plate.

[0010] Preferably, positioning plates are fixedly installed on both sides of the mounting plate, and a sliding rod is slidably installed through the middle of the positioning plate. A pressure plate is fixedly installed at the lower end of the sliding rod, and a return spring is fixedly installed on the upper surface of the pressure plate. The top end of the return spring is located on the lower surface of the positioning plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) When the cutting position is moved to the position of the cutting blade, the mounting plate is driven to move downward through the output end of the third hydraulic cylinder. This drives the pressure plate to move downward, so that the two pressure plates press on the upper surfaces of the two cardboards respectively, which plays a positioning role for the cardboard and the surface film. When the mounting plate moves downward, due to the return spring, sufficient pressure can be applied to the pressure plate, and the pressure on the cardboard and the surface film is stronger. When the mounting plate moves to a certain distance, the cutting blade will contact the film and cut the film. This device can play a fixed limiting role for the cardboard and the film when cutting the film, preventing the film from deforming due to pressure during cutting.

[0013] (2) The distance between the first electric pressure roller and the conveyor belt is adjusted according to the thickness of the carton. At this time, the output end of the first hydraulic cylinder extends and retracts to drive the mounting frame to move up or down. The side plate is fixed. At this time, the first electric pressure roller and the conveyor belt can be adjusted to cover cartons of different specifications. At this time, the output end of the second hydraulic cylinder extends and retracts, which can drive the clamping plate to move, so that the distance between the two clamping plates is adjusted to the appropriate distance for the carton, which plays a limiting role for the carton, so that this device can cover cartons of different specifications.

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1 As shown, a surface coating equipment for carton production includes a support platform 1. A first hydraulic cylinder 2 is fixedly installed on the upper surface of the support platform 1. An installation frame 3 is installed at the output end of the first hydraulic cylinder 2. A conveyor belt 6 is installed between the inner walls of both sides of the installation frame 3. Positioning rods 4 are fixedly installed on both sides of the upper surface of the support platform 1. Side plates 7 are fixedly installed at the top of each of the two positioning rods 4. The two side plates 7 are slidably disposed through the upper surface of the installation frame 3. A first electric pressure roller 8 is fixedly installed between the two side plates 7. An installation shaft 9 is installed between the top of the two side plates 7. A positioning and cutting assembly 5 is provided on the installation frame 3.

[0021] like Figure 1As shown, a guide roller 11 is rotatably mounted between the two side plates 7. The two guide rollers 11 are located between the first electric pressure roller 8 and the mounting shaft 9. A second electric pressure roller 10 is rotatably mounted between one end of the two side plates 7, which can perform the work of pulling and pressing the film.

[0022] like Figure 1 , 4 As shown, fixing plates 12 are installed on both sides of the upper end of the mounting frame 3. A second hydraulic cylinder 13 is fixedly installed on each of the two fixing plates 12. A clamping plate 14 is installed on the output end of each of the two second hydraulic cylinders 13. When the output end of the second hydraulic cylinder 13 extends or retracts, it can drive the clamping plate 14 to move, so that the distance between the two clamping plates 14 is adjusted to the appropriate distance of the carton, thus limiting the carton.

[0023] like Figure 2 , 3 As shown in Figure 4, the positioning and cutting assembly 5 includes two limiting plates 501, which are respectively fixedly installed on both sides of the upper surface of the mounting frame 3. A top plate 502 is fixedly installed between the top ends of the two limiting plates 501. A third hydraulic cylinder 503 is fixedly installed on the upper surface of the top plate 502. A mounting plate 504 is installed at the output end of the third hydraulic cylinder 503. A cutting blade 505 is installed on the lower surface of the mounting plate 504. Positioning plates 506 are fixedly installed on both sides of the mounting plate 504. A sliding rod 507 is slidably installed through the middle of each positioning plate 506. A pressure plate 509 is fixedly installed at the lower end of the sliding rod 507. A return spring 508 is fixedly installed on the upper surface of the pressure plate 509. The top end of the return spring 508 is located on the lower surface of the positioning plate 506. When the cutting position is moved to the position of the cutting blade 505, the output end of the third hydraulic cylinder 503 drives the mounting plate 504 to move downward, which in turn drives the pressure plate 509 to move downward, so that the two pressure plates 509 press on the upper surfaces of the two cardboards respectively, which plays a role in positioning the cardboard and the surface film. When the mounting plate 504 moves downward, due to the return spring 508, sufficient pressure can be applied to the pressure plate 509, and the pressure on the cardboard and the surface film is stronger. When the mounting plate 504 moves to a certain distance, the cutting blade 505 will also come into contact with the film to cut the film. This device can fix and limit the cardboard and film when cutting the film, preventing the film from deforming due to pressure during cutting.

[0024] The working principle of a surface coating equipment for cardboard box production:

[0025] When using this device to laminate the surface of cartons, firstly, the distance between the first electric pressure roller 8 and the conveyor belt 6 is adjusted according to the thickness of the carton. This is achieved by extending or retracting the output end of the first hydraulic cylinder 12, which drives the mounting frame 3 to move up or down. The side plate 7 is fixed in place. This allows adjustment of the first electric pressure roller 8 and the conveyor belt 6 to laminate cartons of different sizes. Then, the output end of the second hydraulic cylinder 13 extends or retracts, driving the clamping plate 14 to move, adjusting the distance between the two clamping plates 14 to the appropriate distance for the carton size, thus limiting the carton's position and enabling the device to laminate cartons of different sizes. After adjustment, the film cylinder is installed on the mounting shaft 9, and the film passes sequentially through the guide roller 11 and the first electric pressure roller 8. When the cardboard passes under the first electric pressure roller 8, the film is pressed onto the surface of the cardboard. The laminated cardboard continues to move forward to the cutting position. When the cutting blade 505 is in position, the mounting plate 504 is driven downward by the output end of the third hydraulic cylinder 503. This drives the pressure plate 509 downward, so that the two pressure plates 509 press on the upper surfaces of the two cardboards respectively, which plays a role in positioning the cardboard and the surface film. When the mounting plate 504 moves downward, the return spring 508 can apply sufficient pressure to the pressure plate 509, which exerts stronger pressure on the cardboard and the surface film. When the mounting plate 504 moves to a certain distance, the cutting blade 505 will come into contact with the film and cut the film. This device can fix and limit the cardboard and film during film cutting, preventing the film from deforming due to pressure during cutting.

For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
