[0002] PVDF (polyvinylidene fluoride) tubing is a high-performance plastic tubing material. PVDF tubing has excellent chemical stability and can withstand a variety of corrosive chemicals, including strong acids, strong bases, and many organic solvents. This makes it widely used in the chemical processing industry.

[0003] When producing PVDF pipes, it is sometimes necessary to weld two sections of pipe together using an automatic welding device. During welding, the two sections of pipe need to be manually supported before they can be welded. This method is more troublesome, reduces welding efficiency, and increases workload. Moreover, after welding, the welding point solidifies through natural cooling, and the cooling time is long, which will also reduce the overall welding production efficiency. Utility Model Content

When the external power switch of the bidirectional motor is turned on, the output shaft of the bidirectional motor can rotate forward and backward, thereby driving the bidirectional screw rod to rotate.

[0013] As a further improvement of the present application: the outer surfaces of the plurality of uprights are movably sleeved with springs, the plurality of springs are respectively arranged on one side of the plurality of base plates, and the plurality of springs will generate a reverse force when squeezed.

[0027] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways than those described herein. Therefore, the present application is not limited to the specific embodiments disclosed in the following specification.

[0029] like Figures 1 to 4 As shown, the present application provides a fully automatic welding device for PVDF pipes, which comprises:

[0030] Base 1;

[0031] The support box 2 is arranged on one side of the base 1, and a bidirectional screw 201 is provided on both sides of the inner wall of the support box 2 through bearings. The bidirectional screw 201 can rotate because of the bearings, and the outer surface of the bidirectional screw 201 has two threads with different rotation directions connected;

[0032] Two threaded barrels 202 are threadedly sleeved on the outer surface of the bidirectional screw rod 201, and a connecting plate 203 is provided on one side of each of the two threaded barrels 202. The two threaded barrels 202 are respectively connected to two threads of different rotation directions on the outer surface of the bidirectional screw rod 201;

[0033] Two support plates 204 are respectively provided on one side of the two connecting plates 203, and two vertical rods 205 are movably embedded on one side of the two support plates 204. The vertical rods 205 can slide on one side of the two support plates 204;

[0034] A plurality of bottom plates 207 are respectively disposed at one end of the plurality of vertical poles 205;

[0035] Two arc-shaped plates 208 are respectively arranged on one side of the plurality of vertical poles 205, and rubber pads 209 are provided on the inner walls of the two arc-shaped plates 208. The two rubber pads 209 are elastic and soft, and can increase the friction between the two arc-shaped plates 208 and the pipeline.

[0036] like Figures 1 to 4 As shown, a bidirectional motor 210 is installed on one side of the support box 2, and the output shaft of the bidirectional motor 210 is connected to one side of the bidirectional screw rod 201. The outer surfaces of the two arc-shaped plates 208 are provided with pull rods 211. When the external power switch of the bidirectional motor 210 is turned on, the output shaft of the bidirectional motor 210 can rotate forward and backward, thereby driving the bidirectional screw rod 201 to rotate.

[0037] like Figures 1 to 4As shown, springs 206 are movably sleeved on the outer surfaces of the plurality of vertical rods 205 , and the plurality of springs 206 are respectively arranged on one side of the plurality of bottom plates 207 . The plurality of springs 206 will generate a reverse force when squeezed.

[0038] like Figures 1 to 4 As shown, a round rod 3 is provided on one side of the base 1, and a welding mechanism 308 is installed on one side of the base 1. The round rod 3 supports the cylinder 301, and controls the welding mechanism 308 to weld the pipe connection.

[0039] like Figures 1 to 4 As shown, a cylinder 301 is provided at one end of the round rod 3, and a rotating rod 302 is provided on one side of the cylinder 301 through a bearing. The rotating rod 302 can rotate because of the bearing.

[0040] like Figures 1 to 4 As shown, a fan blade 303 is provided on one side of the rotating rod 302, and a plurality of through holes 306 are opened on one side of the cylinder 301. When the fan blade 303 rotates, external air is sucked in through the plurality of through holes 306.

[0041] like Figures 1 to 4 As shown, a ring sleeve 304 is provided on one side of the cylinder 301 , and a motor 305 is fixedly embedded in the inner wall of the ring sleeve 304 . The ring sleeve 304 connects the motor 305 to the cylinder 301 .

[0042] like Figures 1 to 4 As shown, the output shaft of the motor 305 is connected to one side of the rotating rod 302, and a plurality of cross bars 307 are provided on the inner wall of the cylinder 301. When the external power switch of the motor 305 is turned on, the output shaft of the motor 305 drives the rotating rod 302 to rotate, and the plurality of cross bars 307 prevent the fan blades 303 from being exposed.

[0043] When welding PVDF pipe fittings, multiple vertical rods 205 can slide on one side of the two support plates 204 respectively. At this time, the two pull rods 211 are pulled upward to drive the two curved plates 208 to move, and the two sections of pipes are placed on the two support plates 204 respectively. The two pull rods 211 are released, and the elastic force generated by the multiple springs 206 pulls the multiple bottom plates 207, further causing the two curved plates 208 to move downward, further causing the two rubber pads 209 to cling to the outer surfaces of the pipes at both ends, fixing the pipes on the two support plates 204. At this time, the external power switch of the bidirectional motor 210 is turned on, and the output shaft of the bidirectional motor 210 can rotate forward and reverse, thereby driving the bidirectional screw rod 201 to rotate;

[0044] Since the two threaded barrels 202 are respectively connected to the two different rotation direction thread lines on the outer surface of the bidirectional screw rod 201, the two connecting plates 203 can slide on one side of the base 1. Therefore, when the bidirectional screw rod 201 rotates in different directions, the two threaded barrels 202 move relative to or oppositely on their outer surfaces, so that the two sections move in the same direction and contact each other. At this time, the welding mechanism 308 is controlled to weld the pipe connection. Therefore, when welding the pipe, there is no need to manually hold the pipe, which improves the welding efficiency of the pipe. After the pipe welding is completed, the external power switch of the motor 305 is turned on, and then the output shaft of the motor 305 drives the rotating rod 302 to rotate, further causing the fan blades 303 to rotate. When the fan blades 303 rotate, external air is inhaled through multiple through holes 306, and sprayed onto the welded pipe through the gaps between the multiple cross bars 307, thereby increasing the cooling rate of the pipe welding point and improving the overall welding production efficiency.
