Description

Technical Field

[0001] The utility model relates to the technical field of tetrafluoro pipes, and particularly relates to a spraying machine for surface treatment of tetrafluoro pipes with different pipe diameters. Background Technique

[0002] The tetrafluoro pipe is a pipe made of polytetrafluoroethylene, also known as a polytetrafluoroethylene pipe. It is a material with excellent chemical stability, low friction coefficient and high temperature resistance. Spraying machines are commonly used for surface treatment of tetrafluoro pipes. The sprayed coating is usually in liquid form, which is convenient for uniform coating during the spraying process, and the coating can be cured into a hard coating by baking and other methods. A spraying machine is a spraying device that sprays the liquid coating onto the surface to be painted through compressed air or other media to form a uniform coating.

[0003] In the prior art, a Chinese patent with the authorization announcement number of CN117123416A discloses a spraying machine for the surface of wooden furniture, belonging to the field of tetrafluoro pipes.

Detailed implementation manner

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1: As Figures 1 - 3 shown in the technical solution, the present invention provides the following technical solution: In order to solve the problem that the spraying machine is inconvenient to position processing pipes with different pipe diameters, thereby affecting material processing, an extrusion mechanism is disclosed:

[0030] It includes a fixed base 1. A spraying pipe 2 is arranged on the top of the fixed base 1. A spraying material tank 3 is connected to the top of the fixed base 1. A conveying device 4 is installed on the top of the spraying material tank 3. A spray head 5 is connected to the side of the conveying device 4. A PLC controller 6 is installed on the top of the fixed base 1 away from the spraying material tank 3. A connecting seat 101 is fixed on the top of the fixed base 1. An extrusion mechanism for positioning workpieces with different pipe diameters is arranged on the top of the fixed base 1. Three groups of first rollers 102 are installed inside the connecting seat 101. Guide rods 103 are symmetrically fixed on the top of the fixed base 1 near the connecting seat 101. A guide frame 104 slides on the surface of the guide rods 103. A second roller 105 is installed at the bottom of the guide frame 104. A first friction plate 106 is connected to the surface of the wheel of the second roller 105. A first motor 107 is installed on the side of the second roller 105. A second motor 108 is installed on the top of the fixed base 1 near the guide rod 103. A threaded rod 109 is fixed to the output end of the second motor 108. The threaded rod 109 penetrates and is threadedly connected inside the guide frame 104. An external connection seat 110 is fixed on the top of the fixed base 1. The spray head 5 is connected to the inside of the external connection seat 110. An adjustment mechanism for adjusting the spraying distance is arranged inside the external connection seat 110. The guide rod 103 and the guide frame 104 are in sliding connection. The guide frame 104 and the threaded rod 109 are in threaded connection. Both the first roller 102 and the second roller 105 are at an oblique angle. When the spraying machine needs to fix workpieces with different pipe diameters, spraying pipes 2 of different sizes are placed on the surface of the first rollers 102, and the second motor 108 is started;

[0031] When the second motor 108 is started, its output end can drive the threaded rod 109 to rotate. When the threaded rod 109 rotates, it can drive the guide frame 104 to perform threaded sliding. When the guide frame 104 performs threaded sliding, it can slide through the guide rod 103. When the guide frame 104 slides, it can drive the second roller 105 to move. When the second roller 105 moves, it can drive the first friction plate 106 to move to the top of the spraying pipe 2 for extrusion. When the first friction plate 106 is extruded, it can deform to increase the friction force. Then, when the output end of the first motor 107 is started, it can drive the first friction plate 106 to rotate. When the first friction plate 106 rotates, it can drive the spraying pipe 2 to rotate. Since the second roller 105 is at an oblique angle, the first friction plate 106 can push the spraying pipe 2 to rotate forward when rotating. When the spraying pipe 2 rotates forward, it can complete the conveying of the processing pipe, realizing that the spraying machine can convey and process workpieces with different pipe diameters, and reducing the limitation of the spraying machine on the processing pipe diameter.

[0032] Embodiment 2: As Figure 1 、 Figure 2 、 Figure 4 and Figure 5 shown in the technical solution, the present invention provides the following technical solution: To solve the problem that the effect of the spraying machine is different when processing workpieces with different pipe diameters, and smaller pipes will also cause waste of paint, an adjustment mechanism is disclosed:

[0033] The adjusting mechanism includes a distance sensor 111, and the distance sensor 111 is installed inside the external seat 110. Three groups of fixing blocks 112 are symmetrically fixed inside the external seat 110. A fixing rod 113 is fixed between the fixing blocks 112. A guiding block 114 slides on the surface of the fixing rod 113. An electric push rod 115 is connected between the guiding block 114 and the fixing block 112. First rotating shafts 116 are fixed on the right sides of both the guiding block 114 and the fixing block 112. A guiding groove 117 is formed on the back of the spray head 5. A slider 118 slides inside the guiding groove 117. Second rotating shafts 119 are fixed on both the side of the slider 118 and the spray head 5. A lifting frame 120 is rotatably connected between the second rotating shaft 119 and the first rotating shaft 116. The fixing rod 113 and the guiding block 114 are in sliding connection. The guiding groove 117 and the slider 118 are in sliding connection. The first rotating shaft 116, the second rotating shaft 119 and the lifting frame 120 are in transmission connection. A collecting mechanism for collecting the spraying liquid is further arranged inside the external seat 110. When the spraying machine sprays, the conveying device 4 can convey the paint inside the paint spraying tank 3 to the inside of the spray head 5 and spray it out. Before the spray head 5 sprays, the distance sensor 111 can measure the size of the spraying pipe 2;

[0034] After the measurement of the spraying pipe 2 is completed, the data can be fed back to the PLC controller 6. The PLC controller 6 can start the electric push rod 115 to extend. When the electric push rod 115 extends, it can push the guiding block 114 to move. When the guiding block 114 moves, it can slide through the fixing rod 113. When the guiding block 114 slides, it can drive the first rotating shaft 116 to move. When the first rotating shaft 116 moves, it can drive the lifting frame 120 to extend. When the lifting frame 120 extends, it can drive the second rotating shaft 119 to move. While the lifting frame 120 extends, the first rotating shaft 116, the lifting frame 120 and the second rotating shaft 119 can rotate. When the second rotating shaft 119 moves, it can drive the slider 118 to move. When the slider 118 moves, it can slide through the guiding groove 117. When the slider 118 slides, it can push the spray head 5 to move. When the spray head 5 moves, it can change the distance from the spraying pipe 2. The adjustment of the distance between the spray head 5 and the spraying pipe 2 can improve the spraying effect and spraying efficiency of the spraying machine.

[0035] Embodiment 3: As Figure 1 、 Figure 4 and Figure 6 shown in the technical solution, the present invention provides the following technical solution: To solve the problem that the liquid of the spraying machine may drip and cause material waste, on the basis of Embodiment 2, a collecting mechanism is disclosed:

[0036] The collection mechanism includes a drainage groove 121 which is opened on the inner bottom surface of the external connection base 110. A slot 122 is opened on the right side of the external connection base 110. Second friction plates 123 are symmetrically connected inside the slot 122. A collection box 124 is arranged inside the slot 122. When the spraying machine is in use, the fluid ejected by the nozzle 5 may drip inside the external connection base 110. The fluid flows through the drainage groove 121. When the spraying fluid flows to the holes on the side of the drainage groove 121, it can fall inside the collection box 124. When the fluid in the collection box 124 is collected to a certain extent, it can be pulled outwards. When the collection box 124 is pulled, it can squeeze the second friction plates 123. When the second friction plates 123 are squeezed, they can deform due to their own material. When the second friction plates 123 deform, the friction force can be changed. When the friction force of the second friction plates 123 changes, the collection box 124 can slide out of the inside of the slot 122. After the collection box 124 slides out, the fluid can be poured into a designated position for reuse, avoiding waste of paint and reducing the spraying cost.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
