[0015] The advantages and features of the present application will be more readily understood from the detailed description which follows and from the appended claims, taken in conjunction with the accompanying drawings.

[0016] Referring now to the drawings in detail, it is stressed that the particulars shown are by way of example and for purposes of illustrative discussion of the preferred embodiments of the present application only and are presented in the cause of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the application. Figs. 1 to 3 The embodiments of the present application include:

[0017] A kind of gap scraper for resin automatic welding machine, the gap scraper follows installation behind the welding position of the resin automatic welding machine, the gap scraper includes: including tool rest 3, press knife cylinder 1 and tool rest 6, the tool rest 6 is installed with doctor blade;Two parallel limit adjustment long holes 301 are symmetrically arranged in the rear part of tool rest 3, the top end of the telescopic rod of press knife cylinder 1 is installed with pressing plate 2, the pressing plate 2 is symmetrically installed with the adjusting bolt 7 connected with two limit adjustment long holes 301 respectively on both sides, a plurality of tool rest connecting holes 303 are arranged in the front part of tool rest 3, a buffer bolt 4 is installed on each tool rest connecting hole 303, the screw rod tail end of buffer bolt 4 is connected with the top of tool rest 6, and buffer spring 5 is installed on the screw rod between the top of tool rest 6 and tool rest 3.

[0018] Two columns of parallel thimble holes 302 are symmetrically laid on tool rest 3 about center line between the two limit adjustment long holes 301, and in some special cases, thimble can be installed in the thimble hole 302 to fix the position of pressing plate 2 on tool rest 3 by pressing from both sides.

[0019] The bottom of the cutter holder 6 is sequentially provided with seven scrapers from front to back, namely, a first scraper 601, a second scraper 602, a third scraper 603, a fourth scraper 604, a fifth scraper 605, a sixth scraper 606 and a seventh scraper 607, and the seven scrapers are divided into two groups, one group is a cutting group and the other group is a leveling group. The cutting group comprises the first scraper 601, the second scraper 602, the third scraper 603 and the fourth scraper 604, wherein the first scraper 601 is a one-way flat scraper, the second scraper 602 and the third scraper 603 are inclined scrapers with a scraper edge angle of 45°, and the fourth scraper 604 is a two-way flat scraper. The heights of the scraper edges of the cutting group sequentially decrease from high to low, and the height difference between the first scraper 601 and the fourth scraper 604 is 2mm±0.1mm, the height difference between the second scraper 602 and the fourth scraper 604 is 1.3mm±0.1mm, and the height difference between the third scraper 603 and the fourth scraper 604 is 0.6mm±0.1mm. In this way, the seven scrapers can effectively remove the raised part of the weld. The leveling group comprises the fifth scraper 605, the sixth scraper 606 and the seventh scraper 607, and the heights of the scraper edges of the leveling group are all equal to the height of the scraper edge of the fourth scraper 604, so that the surface of the weld after the preliminary removal treatment can be leveled. The seventh scraper 607 is a two-way flat scraper, and the fifth scraper 605 and the sixth scraper 606 are vertical scrapers. In this way, during the subsequent processing, the scrapers of the leveling group can move back and forth on the surface of the weld together with the fourth scraper 604, so as to further improve the flatness of the surface.

[0020] The traditional weld processing is generally performed after the complete welding is finished, at which time the plastic material in the weld has been hardened. However, by means of the present application, the relative position between the pressing plate 2 and the limiting adjusting long hole 301 can be adjusted to make the cutter holder 6 and the welding position keep in a straight line and the position of the scraper edge is slightly lower than the welding position. In this way, after the front welding is finished, the scrapers on the cutter holder 6 following the front welding can be pressed on the weld with a certain pressure under the joint action of the pressing cylinder 1 and the buffer spring 5 on the buffer bolt 4. With the synchronous movement of the front welding position, the seven scrapers can first continuously scrape and remove the raised part on the weld, and then level the surface after the scraping. In this way, the trouble of separate processing of the hardened weld is reduced, the efficiency is high, and the appearance of the weld is neat and beautiful.

[0021] The above description is only an embodiment of the present application, and does not limit the patent range of the present application. Any equivalent structure or equivalent process conversion according to the content of the present application or directly or indirectly used in other related technical fields is also included in the patent protection range of the present application.
