Description

Technical Field

[0001] The utility model relates to the technical field of plastic welding, in particular to a plastic welding device with multi-size positioning. Background Technique

[0002] Plastic welding refers to a connection method in which the contact surfaces of two plastic parts are simultaneously melted by heating, so as to combine them into a whole. It is only applicable to the connection of thermoplastic plastics. When welding, a welding rod can be used or not. When using a welding rod, the end faces of the parts to be welded need to be made into seams with a certain shape (such as U-shaped, X-shaped, etc.), and the molten body of the welding rod is filled into the seams, and the two parts to be welded are connected into one body; when not using a welding rod, the welding surface is heated and melted, and then a vertical pressure is applied to the surface to be welded until it is tightly fused into one body. After retrieval, a welding device for plastic product production with the Chinese patent publication number CN210234045U and the application number CN201921021396.2 includes a main body frame. Six groups of rollers are rotatably installed inside the main body frame. One side of the top of the main body frame is fixedly installed with a first fixing frame, and a first electric push rod is fixedly installed on the first fixing frame. The bottom of the first electric push rod is fixedly installed with a first shock-absorbing spring, and the bottom of the first shock-absorbing spring is fixedly installed with a pressing plate. The utility model is provided with a first shock-absorbing spring to provide shock absorption when the device is fixed, avoid damage to the plastic plate caused by excessive pressure, and improve the safety of the device.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4, the present utility model provides a technical solution: a heating device 2 is provided at the central part inside the conveying device 1, a horizontal moving mechanism 3 is horizontally arranged directly below the inner top of the conveying device 1, horizontal adjusting mechanisms 4 are horizontally arranged on both sides directly below the horizontal moving mechanism 3, and a vertical fixing mechanism 5 is arranged on one side outside the horizontal adjusting mechanism 4.

[0022] The conveying device 1 is composed of a bottom fixing frame 101, a first shaft 102, rollers 103 and an L-shaped fixing frame 104. The horizontal moving mechanism 3 is composed of a double-headed motor 301, a first fixing plate 302, a first lead screw 303, a first guide rod 304 and a moving plate 305. The horizontal adjusting mechanism 4 is composed of an n-shaped fixing plate 401, a second lead screw 402, a second guide rod 403, a motor 404 and a baffle 405. The vertical fixing mechanism 5 is composed of a second fixing plate 501, a third guide rod 502, a spring 503 and a rotating roller 504.

[0023] The bottom fixing frame 101 is in the shape of a hollow rectangle, and a groove is provided at the central part above the bottom fixing frame 101. The heating device 2 is arranged inside the groove of the bottom fixing frame 101. A number of groups of first shafts 102 are horizontally arranged at intervals inside the bottom fixing frame 101 on both sides of the heating device 2. A group of rollers 103 is arranged on each shaft of the first shaft 102. An L-shaped fixing frame 104 is vertically arranged on one side above the bottom fixing frame 101, which can effectively fix the internal structure, and the rotating rollers can facilitate the movement of the plastic parts above.

[0024] A double-headed motor 301 is horizontally arranged at the central part below the horizontal plate above the L-shaped fixing frame 104. First fixing plates 302 are vertically arranged on both sides of the double-headed motor 301. First lead screws 303 are horizontally arranged on both sides of the double-headed motor 301, and the first lead screws 303 are arranged inside the first fixing plates 302. A first guide rod 304 is horizontally arranged below the first lead screws 303, and the first guide rod 304 is arranged inside the two first fixing plates 302. A moving plate 305 is arranged on each rod of the first lead screws 303, and this structure facilitates the subsequent driving of the plastic parts.

[0025] An n-shaped fixing plate 401 is horizontally arranged directly below each moving plate 305. A second lead screw 402 is horizontally arranged inside the n-shaped fixing plate 401. A number of groups of second guide rods 403 are horizontally arranged below the second lead screw 402. A motor 404 is horizontally arranged at one end of the second lead screw 402. A baffle 405 is vertically arranged on the rods of the second lead screw 402 and the second guide rods 403. This structure can adjust the position of the baffle horizontally, and when it is convenient to dock two groups of plastic parts subsequently, it can be conveniently moved to the designated position at the same time.

[0026] Inside the n-shaped fixing plate 401, a second fixing plate 501 is horizontally arranged. Inside the second fixing plate 501, several groups of third guiding rods 502 are horizontally arranged. On each rod of the third guiding rods 502, a spring 503 is arranged. Right below the third guiding rods 502, a rotating roller 504 is horizontally arranged. This structure can conveniently vertically fix the upper part of the plastic part.

[0027] Working principle: First, place two plastic parts directly above the rollers 103 on both sides of the heating device 2. The rollers 103 can conveniently rotate through the first shaft 102 arranged inside the bottom fixing frame 101. At this time, according to the width dimensions of the two plastic parts, start the motor 404 arranged outside the n-shaped fixing plate 401. At this time, the motor 404 drives the second lead screw 402 to rotate. During the rotation of the second lead screw 402, it drives the baffle 405 to perform a stable horizontal displacement on the second guiding rods 403. According to the width of the plastic part, the baffle 405 drives the plastic part to displace different distances, so that when it is subsequently moved above the heating device 2 for docking, it can reach the same displacement at the same time. At this time, start the double-headed motor 301. The double-headed motor 301 drives the first lead screws 303 on both sides to rotate inside the first fixing plate 302. During the rotation of the first lead screws 303, they drive the moving plate 305 to move on the rods of the first guiding rods 304. Since the baffle 405 inside the n-shaped fixing plate 401 is arranged directly below the moving plate 305, at this time, the baffle 405 will drive the plastic part to displace under the drive of the movement of the moving plate 305. During the movement, outside the n-shaped fixing plate 401, a second fixing plate 501 is horizontally arranged. Springs 503 are arranged outside several groups of third guiding rods 502 vertically arranged inside the second fixing plate 501. The springs 503 will squeeze the rotating roller 504 directly below. At this time, the plastic part can move stably under the extrusion of the rotating roller 504. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0028] 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 described 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.
