The powder coating device 100 is used to uniformly coat the high molecular powder on the woven reinforcing layer, and the hose production device is used to composite the woven reinforcing layer coated with high molecular powder to form a base material, and the base material is made into an inner lining hose. In this way, since the base material of the inner lining hose is compounded with high molecular powder, the peeling strength and toughness of the inner lining hose can be improved, the product quality of the inner lining hose can be improved, and the service life of the inner lining hose can be prolonged.

[0038] In the embodiment, the powder distributing device 100 uniformly applies the polymer powder on the woven reinforcing layer made of polyester staple fiber material, but is not limited thereto. In other embodiments, the powder can be low molecular powder, and the powder distributing device 100 can apply the powder on the strip 300 made of other materials, without specific limitation on the relative molecular mass of the powder and the material of the strip 300.

[0039] The powder distributing device 100 includes a frame 110, a powder storage hopper 120, a first driving mechanism 130, a distributing roller 140, a supporting seat 150, a second driving mechanism 160, a swing brush 170, a conveying mechanism 180, a third driving mechanism 190, a powder feeding hopper 200, a fourth driving mechanism 210, and an electrostatic eliminator 220. The first driving mechanism 130 is mounted on the frame 110 and connected with the distributing roller 140, and is configured to drive the distributing roller 140 to rotate. The powder storage hopper 120 is fixedly connected with the frame 110 and disposed above the distributing roller 140, and is configured to store the powder and allow the powder to fall onto the distributing roller 140 under the action of gravity. The supporting seat 150 is mounted on the frame 110 and rotationally connected with the swing brush 170, and the swing brush 170 is configured to rotate relative to the supporting seat 150. The second driving mechanism 160 is mounted on the supporting seat 150 and drivingly connected with the swing brush 170, and the swing brush 170 is disposed on one side of the distributing roller 140, and the second driving mechanism 160 is configured to drive the swing brush 170 to swing relative to the distributing roller 140. The conveying mechanism 180 is mounted on the frame 110 and disposed below the distributing roller 140, and is configured to drive the strip 300 to feed forward. Specifically, in the process of driving the strip 300 to feed forward by the conveying mechanism 180, the distributing roller 140 is configured to drive the powder falling from the powder storage hopper 120 to rotate towards the swing brush 170 under the action of the first driving mechanism 130, and the swing brush 170 is configured to swing under the action of the second driving mechanism 160 to brush off the powder adhered on the distributing roller 140, so that the powder is uniformly scattered on the strip 300. In this way, the powder distributing device 100 can uniformly apply the powder on the continuously running strip 300 to realize automatic powder application, with high mechanization degree, time and labor saving, high powder distribution efficiency, good powder application effect, and good powder uniformity.

[0040] It should be noted that the third driving mechanism 190 is installed on the rack 110 and connected with the powder feeding hopper 200, the powder feeding hopper 200 is arranged above the powder storage hopper 120, and the third driving mechanism 190 is used to drive the powder feeding hopper 200 to move along the length direction of the powder storage hopper 120. Specifically, the third driving mechanism 190 is an electric cylinder, the powder feeding hopper 200 is filled with powder, and in the process of feeding the powder on the powder storage hopper 120, the third driving mechanism 190 is used to drive the powder feeding hopper 200 to move along the length direction of the powder storage hopper 120, and in this process, the powder in the powder feeding hopper 200 falls into the powder storage hopper 120 under the action of gravity and is uniformly distributed along the length direction of the powder storage hopper 120.

[0041] Further, the length direction of the powder storage hopper 120 is the axial direction of the distribution roller 140, and the powder uniformly distributed along the length direction of the powder storage hopper 120 can fall onto the distribution roller 140 under the action of gravity, so that the powder is uniformly distributed along the axial direction of the distribution roller 140, thereby further improving the uniformity of the distribution. Specifically, the axial direction of the distribution roller 140 is perpendicular to the running direction of the strip 300 and is in the same direction as the width direction of the strip 300, so as to uniformly coat the powder on the continuously running strip 300.

[0042] In the embodiment, the fourth driving mechanism 210 is installed on the rack 110 and connected with the supporting seat 150, and the fourth driving mechanism 210 is used to drive the supporting seat 150 to move, so that the swing brush 170 is separated from the distribution roller 140, thereby facilitating equipment maintenance and cleaning. Specifically, the fourth driving mechanism 210 is a pneumatic cylinder, one end of the pneumatic cylinder is hinged to the rack 110, the other end is hinged to the supporting seat 150, and the supporting seat 150 is hinged to the rack 110; the pneumatic cylinder can drive the supporting seat 150 to rotate relative to the rack 110 in the elongation process, so that the swing brush 170 is separated from the distribution roller 140, thereby facilitating maintenance and cleaning of the swing brush 170 and the distribution roller 140; the pneumatic cylinder can also drive the supporting seat 150 to reversely rotate and reset relative to the rack 110 in the shortening process, so that the swing brush 170 is folded with the distribution roller 140, thereby facilitating the next distribution operation.

[0043] In the embodiment, the static eliminator 220 is installed on the rack 110 and is arranged at a position away from the swing brush 170 on the side of the distribution roller 140, and the static eliminator 220 is used to eliminate static electricity attached to the distribution roller 140, so as to prevent the powder from being adsorbed on the distribution roller 140 and ensure the coating effect of the powder.

[0044] Please refer to Figure 3 and Figure 4The supporting seat 150 comprises a seat body 151, a supporting plate 152, a rotating shaft 153, an adjusting bolt 154, a first powder leakage sieve plate 155 and a second powder leakage sieve plate 156. The seat body 151 is hinged to the rack 110, and the supporting plate 152 is fixedly connected to the seat body 151. The seat body 151 can drive the supporting plate 152 to rotate relative to the rack 110 under the action of the fourth driving mechanism 210, so as to facilitate equipment maintenance and cleaning. One end of the rotating shaft 153 is fixedly connected to the supporting plate 152, and the other end is rotationally matched with the swing brush 170. The axial direction of the rotating shaft 153 is perpendicular to the axial direction of the cloth roller 140. The swing brush 170 can rotate relative to the rotating shaft 153 to swing in the axial direction of the cloth roller 140, so as to brush off the powder attached to the cloth roller 140.

[0045] It should be noted that the adjusting bolt 154 is installed on the seat body 151 and abuts against the swing brush 170. The adjusting bolt 154 is used to adjust the distance between the swing brush 170 and the cloth roller 140, so that the swing brush 170 is close to or away from the cloth roller 140. Specifically, the adjusting bolt 154 is threadedly matched with the seat body 151. The adjusting bolt 154 is arranged below the rotating shaft 153. When the adjusting bolt 154 is tightened relative to the seat body 151, the adjusting bolt 154 moves towards the cloth roller 140, so as to tilt and push out the swing brush 170 towards the cloth roller 140, so that the swing brush 170 is close to the cloth roller 140. When the adjusting bolt 154 is loosened relative to the seat body 151, the adjusting bolt 154 moves away from the cloth roller 140. At this time, the swing brush 170 is lowered and reset under the action of gravity, so that the swing brush 170 is away from the cloth roller 140.

[0046] In the embodiment, the first powder leakage sieve plate 155 and the second powder leakage sieve plate 156 are arranged in a spaced manner and are fixedly connected to the seat body 151.

The first powder leakage sieve plate 155 is provided with a first sieve hole 157, and the second powder leakage sieve plate 156 is provided with a second sieve hole 158. The area of the first sieve hole 157 is greater than the area of the second sieve hole 158. Specifically, in the process of brushing off the powder attached to the cloth roller 140 by the swing brush 170, the powder first falls on the first powder leakage sieve plate 155 under the action of gravity and continues to fall through the first sieve hole 157. In this process, the first powder leakage sieve plate 155 preliminarily screens the powder, so as to improve the uniformity of the screened powder. Subsequently, the powder falls on the second powder leakage sieve plate 156 under the action of gravity and continues to fall through the second sieve hole 158 to the strip 300. In this process, the second powder leakage sieve plate 156 screens the powder again, so as to further improve the uniformity of the screened powder, so as to ensure that the powder is uniformly scattered on the strip 300.

[0047] The swing brush 170 comprises a swing frame 171, a swing rod 172 and a brush body 173. One end of the swing rod 172 is hinged to the swing frame 171, and the other end is rotationally matched with the rotating shaft 153. The swing rod 172 can rotate relative to the swing frame 171 and rotate relative to the rotating shaft 153, so as to realize the swing function of the swing frame 171. The brush body 173 is fixedly connected to the swing frame 171. The brush body 173 can reciprocate with the swing of the swing frame 171, so as to brush off the powder attached to the cloth roller 140.

[0048] The cloth roller 140 comprises a roller body 141 and a plurality of stop pins 142. The first driving mechanism 130 is connected with the roller body 141, and is used to drive the roller body 141 to rotate. The plurality of stop pins 142 are arranged at intervals on the circumferential surface of the roller body 141. The stop pins 142 are used to stop the powder falling on the roller body 141, so that the powder is attached to the circumferential surface of the roller body 141, thereby enabling the powder to rotate with the roller body 141 and be brushed off under the action of the swing brush 170. Specifically, the brush body 173 is elastic. The brush body 173 passes through the stop pins 142 and is arranged in close contact with the circumferential surface of the roller body 141. During the swing of the swing brush 170, part of the brush body 173 will be elastically deformed under the stopping action of the stop pins 142, and will be reset when leaving the stop pins 142, so as to ensure that the powder located between the plurality of stop pins 142 is completely brushed off, to avoid the waste of powder and improve the cloth effect.

[0049] In the embodiment, the bottom of the powder storage hopper 120 is provided with a first scraper 121 and a second scraper 122. The first scraper 121 and the second scraper 122 are arranged at two sides of the powder storage hopper 120 opposite to each other.

The first scraper 121, the swing brush 170 and the second scraper 122 are sequentially arranged along the rotating direction of the cloth roller 140. The first scraper 121 is used to scrape part of the powder attached to the cloth roller 140, so as to ensure that the height of the powder attached to the cloth roller 140 is equal to the length of the stop pins 142, thereby enabling the plurality of stop pins 142 to stop all the powder falling on the roller body 141, improving the stopping effect and preventing the powder from falling off naturally. The second scraper 122 is used to stop the powder, so as to prevent the powder from falling out from the side of the cloth roller 140 away from the swing brush 170, thereby ensuring the cloth effect of the powder and avoiding the waste of powder.
