Description

Technical Field

[0001] The utility model relates to the field of silk screen curing, in particular to a silk screen curing device for plastic packaging bottles of washing products. Background Art

[0002] Screen printing curing technology is a process widely used in the printing field. Screen printing is a process in which ink is transferred to the substrate through the mesh of the graphic part of the screen by squeezing the ink with a scraper. Screen printing curing is an essential step after screen printing. Its purpose is to make the ink dry quickly and firmly adhere to the surface of the substrate.

[0003] During the curing process of the silk-screen printing on the surface of the plastic packaging bottles of washing and care products, the packaging bottles need to be immediately sent to the silk-screen curing device. The packaging bottles pass through the irradiation area of ​​the ultraviolet curing lamp at a uniform speed on the conveyor belt. The ultraviolet curing lamp emits ultraviolet light of a specific wavelength and intensity to irradiate the ink on the surface of the packaging bottles. The ultraviolet light prompts the photoinitiator in the ink to quickly trigger a polymerization reaction, curing the ink in a short time.

[0004] At present, during the process of fixing the silk screen printed on the surface of the plastic packaging bottle of the washing and care products, the silk screen curing device cures the silk screen on the packaging bottle through the ultraviolet curing lamps on the two sides or the top of the interior. Since the ultraviolet curing lamps on the two sides or the top of the silk screen curing device have blind spots when irradiating the packaging bottle, the silk screen curing device has a poor curing effect on the silk screen on the packaging bottle. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a silk screen curing device for plastic packaging bottles of washing products, so as to solve the technical problem that the ultraviolet curing lamps on both sides or the top of the existing silk screen curing device have blind spots when irradiating the packaging bottles, resulting in poor curing effect of the silk screen curing device on the packaging bottles.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a silk-screen curing device for plastic packaging bottles of washing products, comprising a curing device body, a curing bin installed on the top of the curing device body, an ultraviolet lamp board fixed to the inner wall of the curing bin, a driving plate installed on the inner wall of the curing bin, a controller provided on one side of the curing device body, a conveyor belt installed inside the curing device body, a fixed ring provided on the top of the conveyor belt, a rotating cylinder movably connected to the inner wall of the fixed ring, and packaging bottles placed inside the rotating cylinder.

[0007] By adopting the above technical solution, the technical problem that the ultraviolet curing lamps on both sides or the top of the existing silk screen curing device have blind spots when irradiating the packaging bottles, resulting in poor curing effect of the silk screen printing on the packaging bottles by the silk screen curing device is solved. The ultraviolet lamp boards on both sides of the curing chamber emit ultraviolet light. When the packaging bottle contacts the driving plate, the driving plate contacts and squeezes the surface of the packaging bottle. The squeezing friction of the driving plate causes the packaging bottle to drive the rotating cylinder at the bottom to rotate in the fixed circle. The rotation of the packaging bottle in the rotating cylinder enables the silk screen printing on the outer wall of the packaging bottle to be irradiated by ultraviolet light in all directions, thereby increasing the irradiation area of ​​the ultraviolet lamp board to the packaging bottle.

[0008] The present invention is further configured such that the inner wall of the curing bin is configured to be arched, and a reflective plate is installed on the inner wall of the curing bin.

[0009] By adopting the above technical solution, the reflector installed on the inner wall of the curing chamber reflects the ultraviolet light emitted by the ultraviolet lamp board, so that the ultraviolet light is reflected onto the packaging bottle, thereby increasing the irradiation efficiency of the ultraviolet lamp board on the packaging bottle.

[0010] The utility model is further configured such that the end portion of the driving plate is configured to be arc-shaped, and one side of the driving plate contacts and presses against the surface of the packaging bottle.

[0011] By adopting the above technical solution, the end of the driving plate is set to be arc-shaped, in order to reduce the squeezing damage to the packaging bottle caused by the corners of the driving plate.

[0012] The present invention is further configured such that a protrusion is fixed on the outer wall of the rotating cylinder, a groove is provided inside the fixing ring, and a plurality of groups of balls are installed inside the groove.

[0013] By adopting the above technical solution, the rotating cylinder is embedded in the groove inside the fixing ring through the protrusion, and the balls arranged inside the groove can reduce the friction between the protrusion and the inner wall of the groove.

[0014] The utility model is further configured such that the bottom of the fixing ring is connected with a connecting seat, and the connecting seat is elastic and fixedly mounted on the surface of the conveyor belt.

[0015] By adopting the above technical solution, the fixing ring is installed on the surface of the conveyor belt through the connecting seat. The connecting seat has a certain elasticity, so that the deformation of the fixing ring can be reduced when the fixing ring is at the end of the conveyor belt.

[0016] The present invention is further configured such that a cylinder bottom is fixed to the bottom of the rotating cylinder, and the bottom of the cylinder bottom is higher than the top of the connecting seat.

[0017] By adopting the above technical solution, the bottom of the rotating drum is suspended above the connecting seat, thereby reducing the friction resistance encountered by the rotating drum during rotation and allowing the packaging bottles inside the rotating drum to rotate easily.

[0018] The present invention is further configured such that a fixing seat is fixed on the top of the fixing ring, and the inner wall diameter of the fixing seat is larger than the inner wall diameter of the rotating cylinder.

[0019] By adopting the above technical solution, the fixing seat limits and fixes the packaging bottle placed in the rotating drum, thereby preventing the packaging bottle from shaking during the rotation process.

[0020] The present invention is further configured such that the inner wall of the fixing seat is configured to be conical, so as to facilitate the placement of the packaging bottle inside the fixing seat.

[0021] By adopting the above technical solution, the inner wall of the top of the fixing seat is set to be conical, so that the diameter of the inner wall of the top of the fixing seat is larger than the inner wall of the bottom of the fixing seat, thereby making it convenient for people to place the packaging bottles in the rotating cylinder.

[0022] In summary, the present invention has the following beneficial effects:

[0023] 1. The present invention solves the technical problem that the ultraviolet curing lamps on both sides or the top of the existing silk screen curing device have blind spots when irradiating the packaging bottles, resulting in poor curing effect of the silk screen printing on the packaging bottles. The ultraviolet lamp boards on both sides of the curing chamber emit ultraviolet light. When the packaging bottle contacts the driving plate, the driving plate contacts and squeezes the surface of the packaging bottle. The squeezing friction of the driving plate causes the packaging bottle to drive the rotating cylinder at the bottom to rotate in the fixing ring. The rotation of the packaging bottle in the rotating cylinder allows the silk screen printing on the outer wall of the packaging bottle to be irradiated by ultraviolet light in all directions, thereby increasing the irradiation area of ​​the ultraviolet lamp board on the packaging bottle.

[0024] 2. The utility model provides a reflector, protrusions, grooves and balls. The reflector installed on the inner wall of the curing chamber reflects the ultraviolet light emitted by the ultraviolet lamp board, so that the ultraviolet light is reflected onto the packaging bottles, thereby increasing the irradiation efficiency of the ultraviolet lamp board on the packaging bottles. In addition, the rotating cylinder is embedded in the groove inside the fixing ring through the protrusions on the outer wall. A plurality of balls are installed in the groove, which reduces the friction between the protrusion and the inner wall of the groove, so that the packaging bottles can rotate more smoothly in the rotating cylinder.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] The following describes an embodiment of the present invention based on its overall structure.

[0032] A screen printing curing device for plastic packaging bottles of cleaning products, such as Figure 1 - Figure 4 As shown, it includes a curing device body 1, a curing chamber 3 is installed on the top of the curing device body 1, an ultraviolet lamp board 6 is fixed on the inner wall of the curing chamber 3, a driving plate 302 is installed on the inner wall of the curing chamber 3, a controller 101 is provided on one side of the curing device body 1, a conveyor belt 2 is installed inside the curing device body 1, a fixing ring 401 is provided on the top of the conveyor belt 2, a rotating cylinder 402 is movably connected to the inner wall of the fixing ring 401, and a packaging bottle 5 is placed inside the rotating cylinder 402, which solves the problem that the ultraviolet curing lamps on both sides or the top of the existing screen printing curing device have problems when irradiating the packaging bottles. The blind area of ​​the radiation leads to a technical problem that the silk screen curing device has a poor curing effect on the silk screen printing on the packaging bottle. The ultraviolet lamp boards 6 on both sides of the curing chamber 3 emit ultraviolet light. When the packaging bottle 5 contacts the driving plate 302, the driving plate 302 contacts and squeezes the surface of the packaging bottle 5. The squeezing friction of the driving plate 302 causes the packaging bottle 5 to drive the rotating cylinder 402 at the bottom to rotate in the fixed ring 401. The rotation of the packaging bottle 5 in the rotating cylinder 402 allows the silk screen printing on the outer wall of the packaging bottle 5 to be irradiated by ultraviolet light in all directions, thereby increasing the irradiation area of ​​the ultraviolet lamp board 6 on the packaging bottle 5.

[0033] See also Figure 2The inner wall of the curing chamber 3 is set to be arched, and a reflective plate 301 is installed on the inner wall of the curing chamber 3. The reflective plate 301 installed on the inner wall of the curing chamber 3 reflects the ultraviolet light emitted by the ultraviolet lamp board 6, so that the ultraviolet light is reflected onto the packaging bottle 5, thereby increasing the irradiation efficiency of the ultraviolet lamp board 6 on the packaging bottle.

[0034] See also Figure 3 The end of the driving plate 302 is set to be arc-shaped, and one side of the driving plate 302 contacts and squeezes the surface of the packaging bottle 5. The end of the driving plate 302 is set to be arc-shaped to reduce the squeezing damage of the corners of the driving plate 302 to the packaging bottle 5.

[0035] See also Figure 4 A protrusion 403 is fixed on the outer wall of the rotating cylinder 402, a groove 404 is provided inside the fixing ring 401, and multiple groups of balls 405 are installed inside the groove 404. The rotating cylinder 402 is embedded in the groove 404 inside the fixing ring 401 through the protrusion 403. At the same time, the balls 405 arranged inside the groove 404 can reduce the friction between the protrusion 403 and the inner wall of the groove 404.

[0036] See also Figure 3 and Figure 4 The bottom of the fixed ring 401 is connected to a connecting seat 406, and the connecting seat 406 is elastic, and the connecting seat 406 is fixedly installed on the surface of the conveyor belt 2. The fixed ring 401 is installed on the surface of the conveyor belt 2 through the connecting seat 406. The connecting seat 406 has a certain elasticity, so that the fixed ring 401 can reduce the deformation of the fixed ring 401 when it is at the end of the conveyor belt 2.

[0037] See also Figure 4 A bottom 407 is fixed to the bottom of the rotating cylinder 402, and the bottom of the cylinder bottom 407 is higher than the top of the connecting seat 406. The bottom 407 of the rotating cylinder 402 is suspended above the connecting seat 406, thereby reducing the friction resistance encountered by the rotating cylinder 402 during rotation, so that the packaging bottles 5 inside the rotating cylinder 402 can rotate easily.

[0038] See also Figure 4 A fixing seat 4 is fixed on the top of the fixing ring 401, and the inner wall diameter of the fixing seat 4 is larger than the inner wall diameter of the rotating cylinder 402. The fixing seat 4 limits and fixes the packaging bottle 5 placed in the rotating cylinder 402 to prevent the packaging bottle 5 from shaking during rotation.

[0039] See also Figure 4 The inner wall of the fixing seat 4 is set to be conical, which is convenient for placing the packaging bottle 5 inside the fixing seat 4. The inner wall of the top of the fixing seat 4 is set to be conical, so that the diameter of the inner wall at the top of the fixing seat 4 is larger than the inner wall at the bottom of the fixing seat 4, thereby making it convenient for people to place the packaging bottle 5 in the rotating cylinder 402.

[0040] The working principle of the present invention is as follows: first, the operating speed of the conveyor belt 2 is adjusted by the controller 101, and then the packaging bottle with silk screen printing is placed in the fixing seat 4. The conveyor belt 2 conveys the packaging bottle in the fixing seat 4 to the curing chamber 3. The ultraviolet lamp panels 6 on both sides of the interior of the curing chamber 3 emit ultraviolet light. At the same time, the inner wall of the curing chamber 3 is installed with a reflector 301, so that the ultraviolet light irradiated on the reflector 301 is reflected, thereby increasing the irradiation efficiency of the ultraviolet lamp panel 6 on the packaging bottle. When the packaging bottle contacts the driving plate 302, the driving plate 302 contacts and squeezes the surface of the packaging bottle. The packaging bottle is squeezed and rubbed by the driving plate 302. The rubbing causes the packaging bottle 302 to drive the rotating cylinder 402 at the bottom to rotate in the fixed ring 401. The rotating cylinder 402 is embedded in the groove 404 inside the fixed ring 401 through the protrusion 403 on the outer wall. A plurality of balls 405 are installed in the groove 404, thereby reducing the friction between the protrusion 403 and the inner wall of the groove 404. The rotation of the packaging bottle in the rotating cylinder 402 allows the silk screen on the outer wall of the packaging bottle to be irradiated by the ultraviolet light in all directions, thereby increasing the irradiation area of ​​the ultraviolet lamp board 6 on the packaging bottle. During the rotation of the packaging bottle, the fixing seat 4 limits and fixes the packaging bottle to prevent the packaging bottle from shaking during the rotation.
