Technical Field

[0002] Stainless steel pipe is a hollow long round steel, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instrumentation, and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures, and is also often used as furniture and kitchen utensils.

[0003] The existing application number is CN202022238683.8, which is a wear-resistant and bend-resistant stainless steel pipe. The wear-resistant and bend-resistant stainless steel pipe includes a stainless steel pipe. A central reinforcing rod is provided inside the stainless steel pipe. The central reinforcing rod is fixedly connected to the inner wall of the stainless steel pipe. A shielding frame is provided at the bottom of the central reinforcing rod. A foldable covering sheet is formed at the bottom of the shielding frame. A fixed plate is provided on one side of the shielding frame, which is fixedly connected to the shielding frame.

As the rotating shell 161 rotates, the synchronous rotation of the movable plug-in rotating shaft 162 on the rear side will be realized, and the roller 163 docked on the rear side of the rotating shaft 162 will rotate synchronously and cooperate with the circulating groove opened on the outside to transmit the power to the convex shaft block 164 connected to the bottom, so that the roller 163 as a whole can realize back and forth reciprocating movement, and then the rotating shaft 162 as a whole can move back and forth accordingly, so that the supporting shell 151 docked on the outer side of the middle part of the rotating shaft 162 can move back and forth, and the cleaning member 154 cooperates with the sponge layers 1546 provided on both sides of the interior to realize the back and forth reciprocating movement of the outer side of the stainless steel pipe body 1 Wiping and cleaning, at the same time, when the rotating shaft 162 rotates, the rotation of the transmission wheel 152 provided inside the lower end of the supporting shell 151 will be synchronously realized. When the transmission wheel 152 rotates, the transmission belt 153 connected to the outside of the transmission wheel 152 will realize the rotation transmission of the top connected rotating ring 1541, so that the rotating ring 1541 rotates along the inner circumference of the upper end of the supporting shell 151. In this way, the sponge layers 1546 on both sides can rotate with the rotating ring 1541 to realize rotational wiping and cleaning of the outer side of the stainless steel pipe body 1, thereby enhancing the cleaning effect of the outer side of the stainless steel pipe body 1. As a result, the outer side of the stainless steel pipe body 1 can be wiped back and forth and wiped in a circular rotation at the same time, so that the outer side of the stainless steel pipe body 1 can be wiped and cleaned efficiently, the appearance of dirt can be reduced, and the dirt can be prevented from affecting the subsequent wear-resistant spraying quality;

[0059] At the same time, when the roller 163 drives the rotating shaft 162 back and forth, the connecting branch 166 connected to the rear side of the roller 163 can be synchronously reciprocated back and forth, so that the support shell 151 connected to the front side of the upper end of the connecting branch 166 can enhance the stability of the reciprocating movement, and the rear side of the roller 163 is movably limited and connected with the transmission rod 1422 provided inside the clamp assembly 142, so that when the roller 163 reciprocates back and forth, the transmission rod 1422 can still rotate, so that the stainless steel pipe body 1 clamped by the clamp assembly 142 can realize the reciprocating and rotating wiping cleaning activities, and can also realize the automatic rearward movement of the feeding and placement coordination, so as to achieve the efficient spraying preparation activities of the stainless steel pipe body 1.

[0060] See also Figure 12-14 The positioning assembly 144 in this embodiment includes a turntable 1441 installed on the rear side of the bracket 141, a first motor 1442 connected to the rear side of the turntable 1441, a rotating structure 17 installed inside the turntable 1441 to realize the rotational spraying of the connected stainless steel pipe body 1, and four positioning structures 18 equidistantly installed along the front side of the turntable 1441 and connected to the rotating structure 17.

[0061] Specifically, the rotating structure 17 includes a second motor 171 installed at the middle end of the turntable 1441, a main gear 172 connected to the front side of the second motor 171, and sub-gears 173 installed equidistantly along the four sides of the turntable 1441 and meshingly connected with the four sides of the outer end of the main gear 172. In this way, the sub-gears 173 at the four sides can rotate simultaneously with the main gear 172.

[0062] Specifically, the positioning structure 18 includes four positioning shafts 181 equidistantly installed along the outer side of the turntable 1441 and connected to the middle of the four sub-gears 173, a pressure block 182 symmetrically connected to the positioning shaft 181 for rotatable downward pressure transmission, a tension spring 183 connected to the side of the pressure block 182 to provide an elastic pull-back reset effect, a swing arm 184 docked at the bottom of the pressure block 182 and rotatably connected to the inside of the positioning shaft 181, and a hollow groove is provided on the active side of the swing arm 184, a connecting seat 185 transmission-connected to the side of the swing arm 184 away from the pressure block 182, a telescopic rod 186 installed in the connecting seat 185 for telescopic cooperation, a third compression spring 187 installed on the outside of the telescopic rod 186, and a top block 188 docked at the telescopic end of the telescopic rod 186, and the top block 188 is embedded in the positioning shaft 181, and the top block 188 is arranged as a semi-arc block as a whole.

[0063] Further explanation, when the clamp assembly 142 drives the stainless steel pipe body 1 to move backward, the stainless steel pipe body 1 will be inserted to the outside of the positioning shaft 181, so as to realize the longitudinal positioning and placement of the stainless steel pipe body 1. At the same time, during the insertion of the stainless steel pipe body 1, the pressing blocks 182 connected to the upper and lower ends of the extruded positioning shaft 181 are rotated respectively, so that the pressing blocks 182 on both sides are rotated into the interior of the positioning shaft 181. During the rotation process, the swing arm 184 connected to the inner side is driven to realize the swinging movement of the swing arm 184, and at the same time, the side is pulled The tension spring 183 connected thereto makes the tension spring 183 in a stretched state, and as the swing arm 184 swings, the connecting seat 185 connected to the other side of the swing arm 184 will push outwardly toward the positioning shaft 181, so that the top block 188 connected to the telescopic rod 186 provided inside the connecting seat 185 moves out of the positioning shaft 181 to contact with the inside of the stainless steel pipe body 1, thereby improving the longitudinal placement stability of the stainless steel pipe body 1. At the same time, the third compression spring 187 installed on the outside of the telescopic rod 186 will move with the external push to achieve compression, thereby Improve the compacting and reinforcing effect of the outer top block 188, so that the stainless steel pipe body 1 can be stably placed longitudinally for spraying preparation, and when the spraying activity is completed later, the first motor 1442 connected to the rear side of the turntable 1441 can be rotated to rotate the turntable 1441 by the first motor 1442, so as to rotate the stainless steel pipe body 1 that has been sprayed to the side, and rotate the new positioning shaft 181 to the upper end to realize the longitudinal positioning and plugging of the new stainless steel pipe body 1, and the stainless steel pipe body 1 rotated to the side is stationary for a period of time. After a certain time, it can be removed from the positioning shaft 181. At the same time, the tension springs 183 stretched on both sides of the positioning shaft 181 will realize the pulling and resetting of the pressing block 182 when the stainless steel pipe body 1 is moved out, so that the pressing block 182 is rotated and moved out of the positioning shaft 181. In this way, the swing arm 184 will pull the connecting seat 185 back inward, so as to move the top block 188 back to the inside of the positioning shaft 181, and realize the release and resetting of the compression and reinforcement effect, thereby achieving the advantages of accurate longitudinal positioning and placement of the stainless steel pipe body 1 for auxiliary compression and reinforcement.

[0064] In order to ensure that the placed stainless steel pipe body 1 can achieve sufficient spraying activities, after the stainless steel pipe body 1 completes the positioning and placement activities, the second motor 171 provided inside the turntable 1441 can be driven to enable the second motor 171 to achieve the rotation of the main gear 172 connected to the front output end. When the main gear 172 rotates, the sub-gear 173 connected to the four sides of the outer end of the main gear 172 will rotate at the same time to achieve the circumferential rotation spraying coordination of the placed stainless steel pipe body 1, so that the spraying agent can be fully sprayed to the outside of the stainless steel pipe body 1, thereby enhancing the spraying quality of the stainless steel pipe body 1.
