Description

Technical Field

[0001] The utility model relates to the technical field of preparation and spraying, in particular to a coating spraying device for a paper cup cover. Background Art

[0002] Polylactic acid (PLA) is one of the more promising biodegradable materials, capable of complete degradation in the natural environment. Therefore, some companies are currently using PLA instead of polyethylene to produce paper cups and cup lids. Typically, PLA is sprayed onto the base paper during the coating process, and then the cups and lids are made. However, since a lot of waste paper needs to be cut during the production process, and the waste paper also has a film layer on it, it is not convenient for recycling the waste paper later, resulting in a large waste of film material. The small size of the paper cup lid makes it difficult to place it in the jig, and the spraying effect is difficult to control. It is also relatively difficult to automatically remove it from the jig after spraying. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0025] Reference Figure 1-6 , a coating spraying device for a paper cup cover, comprising a base 1, a circulating operation mechanism, a paper cup cover feeding slide 3, a spraying mechanism and a discharge blowing nozzle assembly;

[0026] The circulating operation mechanism includes a chain 2, four gear plates 7, a servo motor and a paper cup cover jig 4. The four gear plates 7 are arranged in a rectangular distribution on the base 1. A rotating shaft is provided at the center of the bottom of the gear plate 7 and is rotatably mounted on the base 1. The rotating shaft on one of the gear plates 7 extends into the base 1 and is connected to the shaft of the servo motor. The chain 2 meshes around the outside of the four gear plates to form a rectangular chain belt. The paper cup cover jig 4 is evenly spaced and the bottom is mounted on the shaft on the chain 2 through two connecting columns 42;

[0027] One of the gear plates 7 is driven by the servo motor to drive the chain 2 to rotate, and the four gear plates 7 can stretch the chain 2 to make it rectangular. The paper cup cover jig 4 is installed on the chain 2. As the chain moves, when the paper cup cover jig moves to the bottom of the paper cup cover feeding slide 3, a paper cup cover will slide down and fall into the jig. At the same time, the paper cup cover on the jig moved to this position is sprayed with a film layer at the spraying mechanism position (the inner side of the paper cup cover faces upward). After the spraying is completed, the chain 2 is moved again. When the jig is carrying the paper cup cover, it will be blown away from the jig when it reaches the discharge nozzle assembly for collection.

[0028] A paper cup lid feeding slide 3 is provided on one side of the rectangular chain belt, two paper cup lid slide rails 31 are provided inside the paper cup lid feeding slide 3, a baffle 32 is provided at the end of the output end of the paper cup lid feeding slide 3, and a drop opening 33 is provided between the end of the output end of the paper cup lid feeding slide 3 and the tail end of the slide rail 31. The drop opening 33 is located directly above the chain 2 and the paper cup lid jig 4 is directly below the drop opening 33 when passing through it;

[0029] The paper cup lids are fed one by one from the input end of the paper cup lid feeding slide 3, placed upside down on the slide rail 31, and slide down to the drop opening 33 to fall. They are prevented from moving forward by inertia and are blocked by the baffle 32. They then fall and can fall accurately into the paper cup lid jig 4.

[0030] The chain 2 is provided with a spraying mechanism at the next station position adjacent to the side of the paper cup lid feeding slide 3. The spraying mechanism includes a spraying device. The spraying device is arranged on a base and the spraying pipe 5 on the spraying device is vertically downwardly aligned with the paper cup lid jig 4.

[0031] The spraying equipment is a conventional spraying equipment, which is installed in the middle of the upper surface of the base (inside the chain). The spraying pipe 5 is pointed downward to spray above the jig, just spraying onto the inner wall of the paper cup lid;

[0032] The discharge blow nozzle assembly includes a large blowing force blow pipe 6 and a small blowing force blow pipe 61. The large blowing force blow pipe 6 and the small blowing force blow pipe 61 are symmetrically provided on both sides of the chain 2 at one side of the last workstation. The large blowing force blow pipe 6 and the small blowing force blow pipe 61 are directed upward at the two sides of the bottom of the paper cup lid jig 4.

[0033] The blowing force given by the large-blowing blowpipe 6 is large, and the blowing force given by the small-blowing blowpipe 61 is small, so that the paper cup cover can be turned over during the blowing process and collected in the collection box (not shown) outside the chain;

[0034] The paper cup cover jig 4 is in the shape of a circular cup cover, a platform 40 is provided on the inner side of the paper cup cover jig 4 , a circular hole is provided in the middle of the paper cup cover jig 4 and a cross bracket 41 is provided on the side wall of the circular hole, and the two connecting columns 42 are installed at the bottom of the cross bracket 41 .

[0035] The paper cup cover is inverted in the paper cup cover fixture 4 and placed on the platform 40. The cross bracket 41 can play a role in installation without affecting the blowing.

[0036] The paper cup lid feeding slide 3 is tilted downward from the input end to the output end, with an inclination angle ranging from 30 to 35 degrees, so as to facilitate sliding down at a certain speed.

[0037] The chain 2 is provided with a slide 8 below the position between two adjacent gear plates 7. The two ends of the slide 8 are curved and tilted downward. To prevent the chain from bending, the slide 8 plays a supporting role, ensuring that the chain is straight and the transport jig will not fall, ensuring levelness.

[0038] The large blowing force blowpipe 6 is on the inner side of the chain, and the small blowing force blowpipe 61 is on the outer side of the chain, so that the paper cup cover is turned over toward the outer side of the chain.

[0039] The paper cup lid jig 4 is provided with an identification label on the side wall outside the chain 2. The jig is identified by a code scanning device or a label identification device, and stops once when it reaches a fixed position, thereby blanking the paper cup lid, spraying the film layer, and blowing out the paper cup lid.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
