Description

Technical Field

[0001] The utility model relates to the technical field of thermos cup spraying equipment, in particular to a full mouth spray positioning fixture tooling. Background Art

[0002] A thermos is generally a water container made of ceramic or stainless steel with a vacuum layer. The vacuum insulation layer can slow the heat dissipation of the water or other liquids contained inside, thereby achieving the purpose of heat preservation. During the production process of a thermos, it is usually necessary to spray a layer of protective paint on the outside of the thermos to achieve an aesthetic effect. Among them, metallic glitter paint is a paint commonly used on the outer surface of thermos. Its paint base contains fine metal powder (such as aluminum powder, copper powder, etc.). When light hits the metal powder, it is reflected through the air film. This metallic glitter paint gives people a pleasant, light and novel feeling. By changing the shape and size of the metal powder, the glitter degree of the metallic glitter paint can also be controlled. On the outside of the metallic glitter paint, a layer of varnish is usually added for protection.

[0003] In the existing technology, the cup body is usually clamped on a fixture, and then the outer wall of the cup is fully sprayed. Since the general fixture tooling cannot completely cover the cup mouth, the sprayed metallic glitter paint and other paints during the full-mouth spraying of the cup body will cause pollution to the inside of the cup mouth, affecting product quality. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a full-mouth spray positioning fixture to solve the problem in the prior art that during the full-mouth spraying process of the cup body, the sprayed metallic glitter paint and other paints cause pollution to the inside of the cup mouth, affecting product quality.

[0005] The utility model solves the above technical problems through the following technical means: a full mouth spray positioning fixture tooling, comprising a cup holder with a cup holder, the cup holder being used to place a cup body, the cup holder comprising a central column, a baffle and a cup mouth airbag being provided on the central column, the bottom of the cup mouth airbag being in contact with the baffle, the central column being hollow to form a cavity, the cup mouth airbag being in communication with the cavity, an air hole being provided on the central column outside the cup mouth airbag area, and an air inlet being provided on the central column for communicating with an external compressed air source;

[0006] The cup mouth airbag is cylindrical, and a number of axially extending pattern grooves are provided on the outer surface of the cylinder. The corresponding baffle is provided with grooves connected to the pattern grooves. All grooves extend outward and are connected to an annular groove. The outer diameter of the annular groove is larger than the outer diameter of the cup mouth at the lower end of the cup body.

[0007] Optionally, a positioning airbag is provided on the top of the center column, and the positioning airbag is communicated with the cavity. The positioning airbag helps to fix the cup body and prevent the cup body from shaking.

[0008] Optionally, the positioning airbag is cylindrical, and both the positioning airbag and the cup opening airbag are spaced apart from the inner wall of the cup body, with the outer diameter of the positioning airbag being smaller than that of the cup opening airbag. The two airbags provide better support and fixation, and the outer diameters of the two airbags make the cup body easier to place and adapt to changes in the cup body's inner diameter.

[0009] Optionally, a driving mechanism for driving the cup holder to rotate is provided at the bottom of the cup holder, facilitating spraying operation.

[0010] Optionally, the elastic modulus of the positioning airbag is smaller than that of the cup mouth airbag, so that the positioning airbag is first expanded into place to play a positioning and fixing role, thereby preventing the cup body from shaking.

[0011] Optionally, the external compressed air source is a micro air pump provided on the cup holder, and the micro air pump is provided to provide a positive pressure source.

[0012] Optionally, an exhaust port is provided on the center column to relieve the pressure of the airbag and facilitate the removal of the cup.

[0013] Beneficial effects of the utility model:

[0014] 1. The utility model arranges a cup mouth airbag and a baffle on the bracket, and the compressed air entering the center column causes the cup mouth airbag to expand rapidly, thereby realizing rapid fixation of the cup body. When the compressed air flows out along the air flow channel formed by the axial patterned grooves on the cylindrical outer surface of the cup mouth airbag, the grooves connected by the patterned grooves on the baffle, and the gap between the lower end of the cup mouth and the annular groove of the cup body, a positive pressure environment is formed in the entire cup mouth area, so that paints such as metallic glitter plastic powder cannot stay or enter the cup mouth to cause pollution during the full mouth spraying process.

[0015] 2. The present invention is also provided with a positioning airbag, the elastic modulus of which is smaller than that of the airbag at the cup mouth, so that under the same positive pressure, the positioning airbag is easier and faster to expand than the airbag at the cup mouth. The positioning airbag extending into the cup body quickly fixes the cup body and reduces the shaking of the cup body. In addition, the use of the airbag and the baffle can reduce the damage caused by the collision of the cup body to avoid affecting the quality. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the terms describing the positional relationship in the figures are only used for illustrative purposes and cannot be understood as limitations on the present invention. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0023] like Figure 1-Figure 4 As shown in FIG, a full mouth spray positioning fixture tooling of the utility model is shown. Figure 1 、 Figure 2 As shown, it includes a cup holder 2 with a cup holder 1, and the cup holder 1 is used to place a cup body 3, and the cup body 3 is a full-mouthed cup body, such as Figure 3 As shown, the cup holder 1 includes a center column 11, on which a baffle 12, a cup mouth airbag 13 and a positioning airbag 14 are provided from bottom to top. The cup mouth airbag 13 is in contact with the baffle 12, and the positioning airbag 14 is located at the top of the center column 11. When the cup body 3 is placed on the cup holder 1, the cup mouth airbag 13 is located at the lower cup mouth of the cup body 3, and the positioning airbag 14 extends into the upper cup body of the cup body 3. The positioning airbag 14 and the cup mouth airbag 13 are both cylindrical and coincide with the cylindrical inner wall of the cup body 3. The outer diameters of the positioning airbag 14 and the cup mouth airbag 13 are slightly smaller than the inner diameter of the inner wall of the cup body 3, so that the positioning airbag 14 and the cup mouth airbag 13 are both fitted with the inner wall gap of the cup body 3, and the outer diameter of the positioning airbag 14 is slightly smaller than the outer diameter of the cup mouth airbag 13. When the airbag is not inflated, the cup body 3 can be freely moved and mounted on the cup holder 1.

[0024] In this embodiment, the center column 11 is hollow, forming a cavity 111. The positioning airbag 14 and the cup rim airbag 13 are both connected to the cavity 111. An air hole is provided on the center column 11 between the positioning airbag 14 and the cup rim airbag 13. The center column 11 is also provided with an air inlet for communicating with an external compressed air source, which is a micro air pump provided on the cup holder 2. The center column 11 is also provided with an exhaust port for venting the pressure in the two airbags and the cavity 111 after spraying is completed, thereby facilitating the removal of the cup body 3.

[0025] In this embodiment, if Figure 3 As shown, the baffle 12 is made of non-metallic materials, such as various hard plastics, etc. When the cup mouth of the cup body 3 is placed on the cup holder 1, it contacts the airbag and the baffle 12 without causing damage and affecting the appearance quality; Figure 4 As shown, a plurality of axially extending pattern grooves 131 are provided on the cylindrical outer surface of the cup mouth airbag 13, and a corresponding groove 121 connected to the pattern groove 131 is provided on the baffle 12. The groove 121 extends outward and is connected to an annular groove 122. The outer diameter of the annular groove 122 is slightly larger than the outer diameter of the cup mouth at the lower end of the cup body 3. When the cup body 3 is placed on the cup holder 1, the lower end of the cup body 3 contacts the baffle 12, and a small annular gap is formed between the annular groove 122 and the outer edge of the cup mouth at the lower end of the cup body 3.

[0026] In this embodiment, the elastic modulus of the positioning airbag 14 is smaller than that of the cup mouth airbag 13. Therefore, under the same positive pressure condition, the positioning airbag 14 is easier and faster to expand than the cup mouth airbag 13. When the cup body 3 is placed on the cup holder 1, compressed air is introduced, and the positioning airbag 14 expands rapidly and presses against the inner wall of the upper cup body 3, completing the fixation of the cup body 3 and preventing the cup body 3 from shaking. Subsequently, the cup mouth airbag 13 expands into place and presses against the inner wall of the cup mouth of the cup body 3. At this time, a positive pressure cavity is formed between the two airbags and the inner wall of the cup body 3, and the compressed air is compressed along the cup mouth airbag 13. 3, the groove 121 connected to the groove 131 on the baffle 12, the annular groove 122 connected to the groove 121, and the gap between the annular groove 122 and the outer edge of the cup mouth at the lower end of the cup body 3 form an air flow channel. Since the air flow channel is small, the compressed air flows out slowly, so that a positive pressure environment is formed in the lower end cup mouth area of the entire cup body 3. During the spraying process, the metallic glitter plastic powder cannot stay or enter the cup mouth of the cup body 3 to cause pollution.

[0027] In this embodiment, a driving mechanism for driving the cup holder 2 to rotate is provided at the bottom of the cup holder 2, so that spraying is convenient and uniform. There are many such driving mechanisms in the prior art, which will not be described in detail here.

[0028] The working principle of this utility model is as follows:

[0029] The cup body 3 is placed on the cup holder 1 by a robot or manually, and the end face of the cup mouth of the cup body 3 contacts the baffle 12. Compressed air enters the cavity 111 of the center column 11 from the air inlet, causing the positioning airbag 14 and the cup mouth airbag 13 to expand rapidly and press against the cup body 3, completing the rapid fixation and positioning of the cup body 3, and then the cup holder 2 can be driven to rotate for spraying.

[0030] During this process, due to the presence of air holes on the center column 11 between the two air bags, a positive pressure cavity is formed between the two air bags and the inner wall of the cup body 3, and the compressed air flows out along the air flow channel formed by the axial patterned groove 131 on the cylindrical outer surface of the cup mouth air bag 13, the groove 121 connected to the patterned groove 131 on the baffle 12, the annular groove 122 connected to the groove 121, and the gap between the annular groove 122 and the outer edge of the cup mouth at the lower end of the cup body 3, so that a positive pressure environment is formed in the lower end cup mouth area of the entire cup body 3, so that during the full mouth spraying of the outer wall of the cup body, paints such as metallic glitter plastic powder cannot stay or enter the inside of the cup mouth to cause pollution. At the same time, since the gaps in the entire air flow channel are very small, a large amount of airflow will not gush out to cause adverse effects on the spraying.

[0031] The above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art will appreciate that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and such modifications or equivalent substitutions shall be encompassed by the claims of the present invention. The techniques, shapes, and structural portions not described in detail in the present invention are well known.
