Detailed Description
To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
Referring to fig. 1, the inventor provides a water-proof film for paper cups and a coating apparatus thereof, which is characterized in that: the spraying system comprises a spraying material generating module, a material conveying module to be sprayed, a spraying thickness double-stage automatic adjusting module, a sprayed material collecting module and the like. The specific realization principle is as follows:
as a preferable structure of the invention, the spraying material generation module comprises a feed opening 1, an extrusion speed reduction motor 2, an extrusion screw shaft 3, a multi-section temperature control module 4, a die head 5 and the like. Wherein, the upper part of the feed inlet 1 is provided with an opening for directly feeding spraying materials. The output shaft of the extrusion speed reduction motor 2 is mechanically connected with the extrusion screw shaft 3, and hot-melt spraying material pipelines are arranged inside the extrusion screw shaft 3 and the die head 5 and are communicated with an output nozzle of the die head 5. Therefore, after the extrusion deceleration motor 2 is started to rotate, the extrusion screw shaft 3 can extrude and feed the spraying material in the feed port 1 along the direction of the screw shaft and extrude the spraying material through the nozzle of the die head 5. In addition, the extrusion screw shaft 3 is provided with a multi-section temperature control module 4, which can perform progressive heating temperature setting treatment on the spraying material (spraying) and realize thermal extrusion of the spraying material under the combined action of the extrusion speed reduction motor 2 and the extrusion screw shaft 3. The die head 5 is provided with a strip-shaped output nozzle for equalizing the pressure of the spraying material and spraying the spraying material at a specified position. Therefore, the spray material generating module is used for hot extrusion work after the spray material reaches a predetermined temperature, pressure and position.
As the preferred structure of the invention, the material conveying module to be sprayed consists of the material 7 to be sprayed, a feeding frame 6, a pressurizing wheel 12 and the like, and the material 7 to be sprayed can be continuously spread and input to the subsequent spraying operation process. The upper part of the feeding frame 6 is provided with a double-opening groove which can be used for supporting a rotating shaft of the material 7 to be sprayed. The bearings are arranged at two ends of the rotating shaft of the material to be sprayed 7, and the outer rings of the bearings are in contact with the double-opening grooves of the material feeding frame 6. Therefore, when the pressure wheel 12 rotates, the material 7 to be sprayed is continuously fed.
As a preferred structure of the present invention, the two-stage automatic spraying thickness adjusting module comprises a first-stage thickness adjusting motor 8, a first-stage pressure wheel adjusting bracket 11, a first-stage pressure wheel adjusting piston 9, a pressure wheel 12, a first-stage pressure wheel adjusting spring 10, a cooling wheel 13, a second-stage thickness adjusting motor 18, a second-stage thickness adjusting synchronous belt assembly 17, a second-stage thickness adjusting cam 16, a second-stage thickness adjusting scraper 14, a second-stage thickness adjusting tension spring 15, a heating groove 26, a heater 27, a vision sensor 19, a vision light module 20, and the like.
Furthermore, the double-stage automatic spraying thickness adjusting module can perform double-stage automatic spraying thickness adjustment, and can realize adjustment of spraying pressure and thickness and collection and recovery of redundant spraying materials. On one hand, because the inside of the first-stage pressure wheel adjusting bracket 11 is provided with a moving cavity of the pressure wheel 12 supporting shaft, when the first-stage thickness adjusting motor 8 rotates, the first-stage pressure wheel adjusting piston 9 can be driven by the screw rod output shaft to move along the moving cavity, and the first-stage pressure wheel adjusting spring 10 is further compressed or released to change the length of the first-stage pressure wheel adjusting spring, so that the spring pre-tightening pressure between the pressure wheel and the cooling wheel is changed, and the adjustment of the first-stage spraying thickness and pressure is realized. On the other hand, the output shaft of the secondary thickness adjusting motor 18 is connected with the driving wheel of the secondary thickness adjusting synchronous belt assembly 17, and when the secondary thickness adjusting motor 18 rotates, power can be transmitted to the driven wheel of the secondary thickness adjusting synchronous belt assembly 17 through a synchronous belt. Since the driven wheel is mechanically connected with the secondary thickness adjusting cam 16, namely, the rotation control of the secondary thickness adjusting motor 18 can indirectly control the angular displacement of the secondary thickness adjusting cam 16. The second-level thickness adjusting scraper 14 adopts a lever structure, one end of the second-level thickness adjusting scraper is a scraper, and the other end of the second-level thickness adjusting scraper is constantly in contact with a second-level thickness adjusting cam 16 through a second-level thickness adjusting tension spring 15. Therefore, when the secondary thickness adjusting cam 16 is rotated, its eccentric feature may change the gap between the secondary thickness adjusting blade 14 and the pressing wheel 12, thereby achieving secondary adjustment of the coating thickness by scraping off the surplus coating material on the pressing wheel 12. The heating tank collects the excessive spray material scraped by the thickness-adjusting scraper, and the heater provided at the bottom of the heating tank facilitates collection of the excessive spray material to a predetermined position. Further, the two-stage automatic spraying thickness adjusting module mainly controls the first-stage thickness adjusting motor 8 and the second-stage thickness adjusting motor 18 according to the dynamic identification of the spraying thickness of the vision sensor 19. As shown in fig. 1, the vision light module 20 and the vision sensor 19 are respectively arranged on 2 surfaces of the sprayed material, the vision sensor 19 can collect surface information on the sprayed material, the light transmittance of the sprayed material under different spraying thicknesses is utilized, and the surface information is compared with standard colors corresponding to different spraying thicknesses, so that whether the existing spraying thickness is too thin or too thick is identified and judged, real-time dynamic approaching of the spraying thickness to a designed value is realized through the control of the first-level thickness adjusting motor 8 and the second-level thickness adjusting motor 18, and material waste caused by overlarge spraying thickness is avoided.
The sprayed material collecting module is composed of a roller wheel assembly 21, an edge cutting tool 23, a blanking frame 24, a sprayed material roll 25 and the like, and can realize edge cutting processing and winding operation of the sprayed material. The roller assembly 21 is unpowered, and freely rolls under the tension of the sprayed material, but provides positioning guide for the edge cutting knife to cut the edge of the sprayed material. Like the loading frame, the unloading frame 24 is provided with double open grooves for supporting the rotating shaft of the sprayed material roll 25, and bearings are arranged at two ends of the rotating shaft of the sprayed material roll 25, and the outer rings of the bearings are in contact with the double open grooves of the loading frame 24. The roll of sprayed material 25 is thus free to rotate within the open slot of the blanking stand 24. When the rotating shaft of the spraying material roll 25 is driven by an external motor, the sprayed material can be driven to be continuously rolled.
In summary, the spraying process of the paper cup waterproof film and the coating equipment thereof designed by the invention mainly comprises the following steps:
(1) hot extrusion treatment of the spray material: the thickness of the spraying material on the hot extrusion pressing wheel after the spraying material reaches the preset temperature, pressure and position is larger than a set value by using the spraying material generating module.
(2) Two-stage automatic adjustment of spraying thickness: the spraying thickness two-stage automatic adjusting module can realize two-stage automatic adjusting of the spraying thickness based on machine vision, can adjust the spraying thickness of the pressure in the spraying process, and collects and recovers redundant spraying materials through the heating groove.
(3) Feeding, conveying and spraying the material to be sprayed: the material to be sprayed is continuously conveyed by the material conveying module to be sprayed, and the spraying operation of the raw material is completed under the combined action of the cooling wheel 13 and the pressurizing wheel 12.
(4) Cooling, edge cutting treatment and collection of the sprayed material: the roller set in the sprayed material collecting module is further cooled and pre-tightened, so that clamping force is provided for the edge cutting tool to cut the sprayed material; the sprayed material can be driven to be continuously rolled up by the driving of a motor arranged outside the rotating shaft of the sprayed material roll.
Different from the current technical situation that the spraying thickness is manually adjusted only by experience, the technical scheme has the following advantages: the spraying system for the spraying paper mainly comprises a spraying material generating module, a to-be-sprayed material conveying module, a spraying thickness double-stage automatic adjusting module, a sprayed material collecting module and the like, can realize double-stage automatic adjustment of spraying pressure and spraying thickness based on vision, and collects and recovers redundant spraying materials. The consistency of the spraying thickness is improved, the spraying thickness is customized according to the requirements of customers, and the waste of spraying materials is avoided.
