Drawings
Other features and effects of the present invention will become apparent from the following detailed description of the embodiments with reference to the accompanying drawings, in which:
FIG. 1 is a schematic view illustrating a conventional glue supply apparatus;
FIG. 2 is a schematic view illustrating an embodiment of the closed circular doctor blade glue supply apparatus according to the present invention; and
fig. 3 is an enlarged partial cross-sectional view illustrating a glue supply area and a dose area of the embodiment.
Detailed Description
Referring to fig. 2 and 3, one embodiment of the sealed circular doctor blade glue supply device of the present invention includes a backing wheel 2, a doctor blade unit 3, a glue supply unit 4, a gasket 5, and a vacuum unit 6.
The scraper unit 3 is spaced from the backing wheel 2, and includes a scraper body 31 capable of rotating around its axis, three blades 32 spaced from the scraper body 31, three fixing members 33 for respectively fixing the blades 32 to the scraper body 31, and three connecting ribs 34 spaced from the scraper body 31.
The backing wheel 2 and the blade unit 3 form a gap 35 through which a substrate 8 can pass. Each of the connecting ribs 34 is connected at both ends thereof to one of the blades 32, respectively, to enhance the stability of the blades 32 during the coating operation. In this embodiment, the fixing member 33 is a bolt.
The glue supply unit 4 is disposed below the backing wheel 2 and the scraper unit 3, and includes a glue material groove wall 41 cooperating with the scraper unit 3 to define a glue material groove 42, a glue inlet 43 formed in the glue material groove wall 41 and communicating with the glue material groove 42, a glue storage barrel 44 for storing a glue material 9, and a glue supply pump 45 having two ends respectively connected to the glue inlet 43 and the glue storage barrel 44.
The glue material groove 42 has a glue supply area 421 communicating with the glue inlet 43 and a dosage area 422 communicating with the glue supply area 421 and the gap 35, and the volume of the dosage area 422 is much smaller than that of the glue supply area 421.
The pad 5 is disposed between the backing wheel 2 and the scraper unit 3, and one end of the pad abuts against the glue groove wall 41. The gasket 5, the glue tank wall 41 and the scraper unit 3 cooperate to define the dosage area 422.
The user can adjust the volume of the dosage area 422 by changing the size of the spacer 5, so as to control how much the glue 9 enters the dosage area 422 from the glue supply area 421, thereby improving the coating precision.
In the embodiment, the material of the gasket 5 is rubber, and a user can select hard rubber or soft rubber according to the requirement, which is not an important technical feature of the present invention and will not be described herein.
The vacuum unit 6 comprises a vacuum tank wall 61 arranged below the back wheel 2 and adjacent to the sizing tank wall 41, a suction opening 62 formed in the vacuum tank wall 61, and a vacuum pump 63 connected to the suction opening 62. The vacuum slot wall 61 cooperates with the backing wheel 2 to define a chamber 64.
In actual operation, the vacuum pump 63 is started to pump air into the chamber 64, so that the chamber 64 is in a vacuum state, and at the same time, the glue supply pump 45 is started to convey the glue 9 in the glue storage barrel 44 to the glue supply area 421 of the glue groove 42, and the amount of the glue 9 conveyed from the glue supply area 421 to the dosage area 422 is adjusted by the gasket 5 to determine the thickness of the glue 9 applied to the object 8, and then the object 8 is driven by rotating the backing wheel 2, so that the object 8 passes through the chamber 64 to remove air bubbles attached to the surface of the object 8, and then the object 8 passes through the dosage area 422, and at this time, the glue 9 can be uniformly coated on the surface of the object 8.
In addition, in the process of coating operation, if one of the blades 32 is worn for a long time, the user only needs to rotate the blade body 31 to rotate the other blades 32 to the corresponding positions adjacent to the dosage zone 422, and the coating operation can be continued without replacing a new set of blades 12 (see fig. 1) as in the conventional method, thereby saving a lot of operation time and further improving the working efficiency of the worker.
From the above description, the advantages of the present invention can be summarized as follows:
firstly, through the high leakproofness of the sizing material groove 42, in the process of coating operation, the outside air can not enter the sizing material groove 42, so that the sizing material 9 is not easy to evaporate and can not deteriorate due to air contact, and the effect of improving the coating quality is achieved.
Secondly, through the characteristic that the blade 32 can rotate along with the scraper body 31, when one blade 32 is abraded, a worker can continue coating operation only by rotating the blade 32, and further the working efficiency is improved.
Thirdly, the volume of the dosage area 422 is adjusted through the arrangement of the gasket 5, so that the coating thickness of the rubber material 9 is controlled, and the effect of improving the coating precision is achieved.
Fourthly, through the arrangement of the vacuum unit 6, before the coated object 8 passes through the dosage area 422, bubbles attached to the surface of the coated object 8 are removed in advance, so that the coating quality of the sizing material 9 is improved, and the reject ratio of products is reduced.
It should be noted that if the coated object 8 is not a delicate product (such as a sticker for a mobile phone screen), the coating material 9 on the surface of the coated object 8 will not affect the aesthetic degree if some air bubbles are mixed in the coating process, so that the present invention can achieve the main inventive effect without the vacuum unit 6, depending on the product requirements of the end-users.
In summary, the present invention achieves the effect of improving the working efficiency and the coating quality by the rotatable characteristic of the scraper unit 3 and the high sealing property of the glue tank 42, so that the object of the present invention can be achieved.
The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and the invention is still within the scope of the present invention by simple equivalent changes and modifications made according to the claims and the contents of the specification.
