Description

Technical Field

[0001] This utility model belongs to the technical field of coating equipment, specifically relating to a high-speed oil-based coating equipment. Background Technology

[0002] Oil-based coating equipment is mainly used for surface coating processes of films, paper, etc. After the film is coated, it needs to be soaked in a water tank to allow the coating to solidify quickly. The film carries moisture as it passes through the water tank, and the solidified layer also contains a large amount of moisture. Therefore, before the film enters the drying oven, excess moisture needs to be removed from the film surface. Existing coating equipment often uses high-speed extrusion for water removal, which has disadvantages such as low removal efficiency and poor effect, and can easily damage the film surface.

[0003] According to a Chinese utility model patent published under publication number CN218308984U: an oil-based coating device, a water removal mechanism is set inside the machine casing. The water removal mechanism includes two sets of rotatable vacuum adsorption rollers and a vacuum pump. After the film is discharged from the water tank, the film is wound around the two vacuum adsorption rollers. The film is wound in an S-shape. The two vacuum adsorption rollers are in contact with the two sides of the film respectively. An air suction structure is connected between the vacuum adsorption rollers and the vacuum pump. The vacuum adsorption rollers can absorb moisture from the two sides of the film.

[0004] However, the above-mentioned device still has some problems when in use. When the water removal mechanism malfunctions, such as a decrease in suction, it can only absorb most of the moisture on the film. If it cannot be detected and dealt with in time, the film with moisture will flow to the next process for processing, resulting in unqualified film and causing economic losses. Utility Model Content

[0005] The purpose of this invention is to provide a high-speed oil-based coating equipment. When the dehydration mechanism inside the machine malfunctions and can only absorb most of the moisture on the film, the subsequent emergency dehydration mechanism can temporarily absorb the moisture remaining on the film, giving the operator enough reaction time to prevent the film with moisture from flowing to the next process and producing unqualified film, resulting in economic losses.

[0006] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0007] A high-speed oil-based coating device includes a chassis with a discharge port through which the film is discharged.

[0026] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort should fall within the protection scope of this utility model.

[0027] like Figures 1 to 5As shown, a high-speed oil-based coating device according to one embodiment of this utility model includes a housing 11 with a discharge port 12, through which a film 13 is discharged. Specifically, a dehydration mechanism is provided inside the housing 11, which includes a vacuum adsorption roller and a vacuum pump. After leaving the water tank, the film 13 can be wound sequentially onto the vacuum adsorption roller. Through the vacuum pump and the suction structure, the vacuum adsorption roller can adsorb the moisture on the film 13, and the film 13 is then drawn out through the discharge port 12 by the traction roller in the next process.

[0028] The device includes a support plate 21, which is mounted on the housing 11 and fixedly connected to the housing 11. The support plate 21 is located on the side of the discharge port 12. An emergency dewatering mechanism is provided on the support plate 21. The emergency dewatering mechanism includes an adsorption roller 31 and an adsorption layer 32 disposed on the adsorption roller 31. The adsorption roller 31 is rotatably disposed at one end of the support plate 21 near the discharge port 12. Two sets of adsorption rollers 31 are arranged side by side, and the two sets of adsorption layers 32 can respectively abut against the two surfaces of the film 13.

[0029] Specifically, the adsorption roller 31 is a commonly used shaft roller in the prior art. A rotating shaft 51 is fixedly connected to one end of the adsorption roller 31 near the support plate 21, and a bearing 52 matching the rotating shaft 51 is fixedly connected to the support plate 21. The rotating shaft 51 can be installed in the inner ring of the bearing 52, such as by welding or pressing. The film 13 is moved by the traction roller. During the movement, the film 13 can drive the adsorption roller 31 and the adsorption layer 32 to rotate, thereby adsorbing the moisture on the film 13.

[0030] Before leaving the discharge port 12 and entering the next processing step, the film 13 can be wound onto two sets of adsorption rollers 31 in sequence. The winding shape of the film 13 is S-shaped. The adsorption layer 32 set on the adsorption rollers 31 is in contact with the two surfaces of the film 13. When the water removal mechanism in the housing 11 has problems such as a decrease in suction that prevents the water on the film 13 from being completely adsorbed, the adsorption layer 32 can temporarily adsorb the water remaining on the film 13, preventing the film 13 with water from flowing to the next processing step.

[0031] If the staff does not discover the problem with the water removal mechanism inside the casing 11 immediately, the subsequent adsorption roller 31 and adsorption layer 32 can also adsorb the moisture on the membrane 13, giving the staff enough time to discover the problem. During the time between the discovery and repair of the water removal mechanism problem, the moisture on the membrane 13 can still be properly adsorbed.

[0032] The adsorption layer 32 is made of a material with strong water absorption capacity, such as water-absorbing sponge and water-absorbing resin, which can temporarily absorb the moisture on the film 13. After the moisture is absorbed, the moisture in the adsorption layer 32 can evaporate naturally for the next use without frequent replacement.

[0033] An adsorption layer 32 has a fixing layer 33 that matches the adsorption roller 31 on its inner side. The fixing layer 33 is fixedly connected to the inner end face of the adsorption layer 32. The fixing layer 33 is made of an elastic material, such as rubber or silicone. The fixing layer 33 can be tightly fitted onto the adsorption roller 31, increasing the stability of the adsorption layer 32 and allowing the adsorption layer 32 to rotate together with the adsorption roller 31.

[0034] A retaining ring 34 is provided on the adsorption roller 31. The retaining ring 34 is detachably provided on the adsorption roller 31. Generally, retaining rings 34 are provided on both sides of the adsorption roller 31. The retaining rings 34 limit the film 13 and prevent the film 13 from falling off. One retaining ring 34 away from the support plate 21 is detachable, which makes it easy to remove the adsorption layer 32 and the fixing layer 33 from the adsorption roller 31 for replacement.

[0035] A fixing plate 35 is fixedly connected to the retaining ring 34, and a fixing bolt 36 is threadedly connected to the fixing plate 35. A threaded hole 37 matching the fixing bolt 36 is opened in the adsorption roller 31. The fixing bolt 36 can be threadedly connected to the fixing plate 35 and the threaded hole 37, which facilitates the installation and removal of the retaining ring 34.

[0036] A retaining ring 34 is fixedly connected to a locking block 38, and the adsorption layer 32 and the fixing layer 33 are provided with locking grooves 39 that match the locking block 38. The locking block 38 can be locked in the locking groove 39. The retaining ring 34 facilitates the removal of the adsorption layer 32 and the fixing layer 33 from the adsorption roller 31, and also facilitates the pushing of the adsorption layer 32 and the fixing layer 33 when they are sleeved on the adsorption roller 31, which is convenient for installation and replacement.

[0037] A protective cover 22 is provided on the support plate 21. A limiting groove 23 is formed on the support plate 21, and a limiting plate 24 matching the limiting groove 23 is fixedly connected to the protective cover 22. The protective cover 22 protects the emergency dewatering mechanism and the detection mechanism on the support plate 21. The protective cover 22 can be pulled down to one side for easy maintenance of the emergency dewatering mechanism and the detection mechanism. A handle 25 is provided on the protective cover 22 for easy pulling.

[0038] The protective cover 22 is provided with an observation window 27, and a baffle 26 corresponding to the observation window 27 is hinged to the protective cover 22. The observation window 27 facilitates the observation of the testing status of the testing agency.

[0039] The detection mechanism includes a detection roller 41 with a rotating hole 43. A limiting shaft 42 matching the detection roller 41 is fixedly connected to the support plate 21. There are two sets of detection rollers 41, which are located in front of two sets of adsorption rollers 31. The two sets of detection layers 44 can respectively abut against the two surfaces of the film 13.

[0040] Specifically, when the film 13 passes through the two sets of detection rollers 41, it can drive the detection rollers 41 to rotate, and the detection layer 44 on the detection rollers 41 can contact the two surfaces of the film 13. The film 13 can pass through the two sets of detection rollers 41 in an S-shape, ensuring that the two surfaces of the film 13 are in contact with the detection layer 44 respectively.

[0041] The detection layer 44 is made of a water-sensitive material, such as water-based screen printing ink. It is white in color, becomes transparent when it comes into contact with water, and returns to its original color after drying. The color of the detection layer 44 can be used to determine whether there is still moisture on the film 13, and thus determine whether there is a problem with the water removal mechanism inside the chassis 11. When the protective cover 22 is closed, the rotating hole 43 can be observed through the observation window 27.

[0042] Furthermore, to save manpower, there is no need to arrange special observers. It is sufficient to observe during the shift handover when the operator stops the machine. Even if there is still residual moisture on the membrane 13, causing the color of the rotating hole 43 to change and not being observed in time, the residual moisture on the membrane 13 can be absorbed by the emergency dewatering mechanism. The dewatering mechanism inside the machine box 11 can be inspected and maintained during the shift handover when the machine stops the machine, without affecting the normal operating time and ensuring output.

[0043] When using, refer to Figures 1-5 As shown, after the film 13 is dehydrated by the dehydration mechanism inside the housing 11, it leaves the housing 11 through the discharge port 12. The film 13 leaving the housing 11 is wound around two sets of adsorption rollers 31 in sequence. The adsorption layer 32 on the adsorption rollers 31 contacts the two surfaces of the film 13 respectively, and then enters the next processing step. When the dehydration mechanism inside the housing 11 has a problem, such as a decrease in suction, which causes it to be unable to completely adsorb the moisture on the film 13, the adsorption layer 32 can adsorb the moisture remaining on the film 13.

[0044] When the dehydration mechanism inside the casing 11 only experiences a decrease in suction but can still absorb most of the moisture, it can prevent the film 13 containing moisture from entering the next processing step. On the other hand, it allows operators enough time to detect the problem. Finally, maintenance can be carried out during the shift handover without affecting normal production.

[0045] Compared with the prior art, the high-speed oil-based coating equipment of this utility model can temporarily absorb the residual moisture on the film when the dehydration mechanism inside the machine box malfunctions and can only absorb most of the moisture on the film. This allows the operators enough reaction time to prevent the film with moisture from flowing to the next process and producing unqualified film, resulting in economic losses.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0047] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
