Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste plastic cleaning and recycling, and particularly relates to a positioning and welding auxiliary device. BACKGROUND

[0002] In the waste plastic cleaning and recycling industry of PET, HDPE and the like, in order to obtain waste plastic of higher quality, photoelectric sorting equipment is used to remove impurities. A prerequisite for normal use of the photoelectric sorting equipment is that the material is uniformly distributed and cannot overlap. A disc screen is usually used to solve this problem. The known disc screen structure comprises a chassis, a plurality of disc screen shafts arranged in parallel are mounted on the chassis, a plurality of uniformly distributed triangular blades are welded on the disc screen shafts, the triangular blades on a previous disc screen shaft are located in the interval between two adjacent triangular blades on a subsequent disc screen shaft, drive sprockets are mounted at both ends of the disc screen shaft, and a drive device drives the disc screen shaft to rotate through a chain transmission. After the material enters the equipment, it intermittently collides with the triangular blades, and the collision imparts kinetic energy to the material for upward and forward displacement, thereby achieving the functions of conveying forward and dispersing the material. In order to prevent the triangular blades on the disc screen shaft from interfering with each other after installation, production personnel need to position each triangular blade in sequence when welding the triangular blades. The wider the width of the disc screen shaft, the more triangular blades there are, and the longer the time spent by the production personnel if rapid positioning cannot be achieved. SUMMARY

[0003] The positioning and welding auxiliary device has the advantages of simple structure, reasonable design, convenient use, and the like.

[0004] To achieve the above-mentioned purpose, the technical scheme adopted by the present application is as follows: it comprises a bent upper shell, upper positioning holes, fixed rib plates, upper welding auxiliary grooves, a bent lower shell, beveled positioning holes, lower positioning holes, lower fixed rib plates, lower welding auxiliary grooves and buckles; the top of the bent upper shell is provided with a plurality of upper positioning holes used in cooperation with the top corners of the triangular blades, the two ends of the bent upper shell are respectively connected with fixed rib plates, the bent bevel of the bent upper shell is provided with upper welding auxiliary grooves, the lower part of the bent upper shell is provided with the bent lower shell, the bent bevel of the bent lower shell is provided with a plurality of beveled positioning holes used in cooperation with the other two corners of the triangular blades in addition to the top corners, the bottom of the bent lower shell is provided with a plurality of lower positioning holes used in cooperation with the lower ends of the triangular blades, the two ends of the bent lower shell are respectively connected with lower fixed rib plates, the lower positioning holes at the bottom of the bent lower shell are provided with lower welding auxiliary grooves, and the bent upper shell and the bent lower shell are fixedly connected through buckles.

[0005] Further, the upper positioning holes are uniformly distributed, and the spacing of the upper positioning holes is equal to the spacing of the triangular blades.

[0006] Further, the inclined positioning holes and the lower positioning holes are uniformly distributed, and the distance between the inclined positioning holes and the lower positioning holes corresponds to the upper positioning holes.

[0007] Further, the distance between the first upper positioning hole, the inclined positioning hole and the lower positioning hole at one end of the bent upper shell and the bent lower shell is equal to half of the distance between two adjacent triangular blades, and the distance between the first upper positioning hole, the inclined positioning hole and the lower positioning hole at the other end of the bent upper shell and the bent lower shell is also equal to half of the distance between two adjacent triangular blades.

[0008] After the above structure is adopted, the positioning and welding auxiliary device has the advantages of compact structure, fast positioning of the triangular blades on the disc screen shaft, auxiliary welding, shortened production cycle, improved production efficiency, simple structure, reasonable setting, low manufacturing cost and the like.

[0014] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the following will briefly introduce the drawings needed to be used in the embodiments or the prior art description. Obviously, the drawings in the following description only some embodiments of the present application, and for those skilled in the art, other drawings can also be obtained from these drawings without creative labor.

[0015] Referring to FIG. 1, Figure 1 Figure 3 ​​​The specific embodiment shown adopts the technical scheme as follows: it comprises a bent upper shell 1, an upper positioning hole 2, a fixed rib plate 3, an upper welding auxiliary groove 4, a bent lower shell 5, an inclined surface positioning hole 6, a lower positioning hole 7, a lower fixed rib plate 8, a lower welding auxiliary groove 9 and a buckle 10; the top of the bent upper shell 1 is provided with a plurality of upper positioning holes 2 used in cooperation with the top corners of triangular blades, the two ends of the bent upper shell 1 are respectively connected with fixed rib plates 3, the bent inclined surface of the bent upper shell 1 is provided with upper welding auxiliary grooves 4, the lower part of the bent upper shell 1 is provided with a bent lower shell 5, the bent inclined surface of the bent lower shell 5 is provided with a plurality of inclined surface positioning holes 6 used in cooperation with the two corners other than the top corners of the triangular blades, the bottom of the bent lower shell 5 is provided with a plurality of lower positioning holes 7 used in cooperation with the lower ends of the triangular blades, the two ends of the bent lower shell 5 are respectively connected with lower fixed rib plates 8, the lower positioning holes 7 at the bottom of the bent lower shell 5 are provided with lower welding auxiliary grooves 9, and the bent upper shell 1 and the bent lower shell 5 are fixedly connected through the buckle 10.

[0016] The upper positioning holes 2 are uniformly distributed, and the interval of the upper positioning holes 2 is equal to the interval of the triangular blades.

[0017] The inclined surface positioning holes 6 and the lower positioning holes 7 are uniformly distributed, and the interval of the inclined surface positioning holes 6 and the lower positioning holes 7 corresponds to the upper positioning holes 2.

[0018] The distance between one end of the bent upper shell 1 and the bent lower shell 5 and the first upper positioning hole 2, the inclined surface positioning hole 6 and the lower positioning hole 7 at the end is equal to half of the interval of the adjacent two triangular blades, and the distance between the other end of the bent upper shell 1 and the bent lower shell 5 and the first upper positioning hole 2, the inclined surface positioning hole 6 and the lower positioning hole 7 at the end is also equal to half of the interval of the adjacent two triangular blades.

[0019] The working principle of the present application is as follows: before the triangular blades are welded to the disc screen shaft, the triangular blades are sequentially placed into the inclined surface positioning holes 6 and the lower positioning holes 7 of the bent lower shell 5, after the placement is completed, the bent upper shell 1 is installed, the triangular blades correspond to the upper positioning holes 2 of the bent upper shell 1, and the fixed connection is achieved through the buckle 10, after the fixation is completed, the bent upper shell 1 and the bent lower shell 5 provided with the triangular blades are sleeved into the disc screen shaft, the triangular blades at the starting position are positioned according to the design requirements, since the interval of the upper positioning holes 2, the inclined surface positioning holes 6 and the lower positioning holes 7 is equal to the interval of the triangular blades, the remaining triangular blades do not need to be sequentially positioned, and the welding fixation is directly performed through the upper welding auxiliary grooves 4 and the lower welding auxiliary grooves 9. Since the distance between one end of the bent upper shell 1 and the bent lower shell 5 and the first upper positioning hole 2, the inclined surface positioning hole 6 and the lower positioning hole 7 at the end is equal to half of the interval of the adjacent two triangular blades, when the subsequent bent upper shell 1 and the bent lower shell 5 provided with the triangular blades are installed, it is not necessary to distinguish the direction, and after the previous set of devices are closely contacted and aligned, the triangular blades can be welded and fixed.
