[0024] Beneficial Effects

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The present invention realizes the function of effectively preventing the hose blank from folding and curling by arranging a stretching component inside the prepreg tank and designing a structure for stretching the flat hose blank, thereby effectively solving the problem that the hose blank may fold and curl when immersed in the prepreg liquid, resulting in the prepreg effect being affected.

[0027] 2. When the present invention is in operation, when it is necessary to pre-impregnate the hose blank, the hose blank can be passed through the interior of the first fixing frame, and then the hose blank can be passed through the bottom of the blocking block, and then the hose blank can be passed through the first clamping roller and the second clamping roller in sequence, and then through the interior of the plate frame, and drawn out from the interior of the second fixing frame, and then the pre-impregnation liquid can be added to the interior of the pre-impregnation tank to pre-impregnate the hose blank, and the hose blank can be stretched by the first clamping roller and the second clamping roller to make the hose blank flatter, so that the pre-impregnation effect can be better, and at the same time, when the hose blank that enters later is folded, the blocking block The conical design of the block can stretch the hose blank and enter the interior of the prepreg tank. At the same time, when the hose blank passes through the blocking block, the flattening roller can reduce the wear between the hose blank and the blocking block. At the same time, the flattening roller can squeeze the hose blank to squeeze out the air inside the hose blank, so that during the storage of the hose blank, air is retained inside the hose blank, which affects the storage of the hose blank. At the same time, when the hose blank passes through the plate rack, the scraper plate can scrape off the prepreg liquid adhering to the surface of the hose blank, thereby reducing the impact of the prepreg liquid adhering to the surface of the hose blank on the use of the finished light-curing hose.

[0028] 3. The present invention adopts a structural design to block the light of the UV lamp by arranging a light-blocking plate between the plate frame and the second fixed frame, thereby effectively preventing the prepreg liquid in the prepreg tank from being affected by the light of the UV lamp, which would cause the prepreg liquid in the prepreg tank to solidify. At the same time, the light-blocking plate can effectively prevent the prepreg liquid in the prepreg tank from splashing onto the surface of the UV lamp, which would affect the irradiation effect of the UV lamp.

[0029] 4. In the present invention, since different prepregs have different light curing speeds when exposed to UV light, it is necessary to adjust the light intensity of the UV lamp. When the light intensity of the UV lamp needs to be adjusted, the rotating rod can be rotated to drive the bevel gear set to rotate, so that the threaded rod can cooperate with the thread of the bevel gear set, so that the height of the second fixed frame can be adjusted, thereby changing the light intensity of the UV lamp, and then adjusting the light curing speed of the prepreg on the surface of the hose blank, so as to achieve a better thickening effect on the prepreg.

[0030] 5. In the present invention, when the second fixing frame is raised upward, the second fixing frame can pull the light shielding plate through the pull rope, thereby shortening the distance between the light shielding plate and the prepreg body, thereby making the angle between the hose blank and the light shielding plate larger, thereby making the contact area between the hose blank and the light shielding plate smaller, and reducing the wear between the hose blank and the light shielding plate; when the second fixing frame is lowered downward, the spring will push the light shielding plate out, thereby increasing the distance between the light shielding plate and the prepreg body, thereby making the shielding effect of the light shielding plate better.

[0031] 6. In the present invention, when the hose blank contacts the second clamping roller and drives the second clamping roller to rotate, the second clamping roller can drive the rotating shaft to rotate through the synchronous belt, so that the rotating shaft can drive the knocking rod to rotate and knock on the knocked plate, thereby causing the inside of the plate frame to vibrate, and then the vibration will be transmitted to the inside of the hose blank inside the plate frame, so that the pre-impregnation liquid on the surface of the hose blank and the surface of the scraper plate can be shaken off, so that the surface of the hose blank and the surface of the scraper plate can be cleaner, and the pre-impregnation liquid can be recycled.

[0032] 7. In the present invention, when the first clamping roller and the second clamping roller clamp the hose blank, the convex strips and the grooves can increase the contact area between the hose blank and the first clamping roller and the second clamping roller, and further increase the roughness between the hose blank and the first clamping roller and the second clamping roller, thereby increasing the friction between the hose blank and the first clamping roller and the second clamping roller, so that the first clamping roller and the second clamping roller can clamp the hose blank better. At the same time, the increased friction can make the rotation effect of the second clamping roller better, thereby effectively avoiding slipping between the second clamping roller and the hose blank, resulting in the second clamping roller not rotating.

[0033] 8. When the knocking rod of the present invention knocks on the side wall of the knocked plate, the arc-shaped knocking rod can make the knocking force stronger, so that the vibration generated by the knocking can be greater, and the vibration cleaning effect is better.

[0034] 9. In the present invention, when the rotating rod rotates, the anti-wear balls can convert the sliding friction between the rotating rod and the prepreg body into rolling friction, thereby reducing the friction between the rotating rod and the prepreg body and causing less wear between the rotating rod and the prepreg body.

[0057] S4: The hose blank is introduced through the prepreg device, and then the hose blank is flattened and pre-impregnated through the stretching component. After the hose blank is soaked in the prepreg device, it is irradiated with a UV lamp for 3-5 seconds to thicken the light-curing prepreg liquid, and then it is rolled into a temperature-controlled transport box for storage and transportation.

[0058] like Figure 2 As shown, the steps of using the prepreg device are as follows:

[0059] S11: introducing the hose blank into the prepreg tank of the prepreg machine body 1 through the first fixing frame 2, and then passing the hose blank through the first clamping roller 5 and the second clamping roller 6 in sequence, and then passing through the middle of the scraper plate 9 inside the plate frame 8, and then leading out through the second fixing frame 7;

[0060] S12: Adding light-curing prepreg liquid into the prepreg tank to soak the hose blank;

[0061] S13: Use a winding device to slowly wind up the hose blank. During the winding process, turn on the UV lamp on the second fixing frame 7 to irradiate the soaked hose blank for 3-5 seconds, so that the light-cured prepreg is thickened and then rolled up.

The hose blank can be stretched by the first clamping roller 5 and the second clamping roller 6 to make the hose blank flatter, so that the pre-impregnation effect can be better. At the same time, when the hose blank that enters later is folded, the conical design of the blocking block 3 The hose blank can be stretched out and then enter the interior of the prepreg tank. At the same time, when the hose blank passes through the blocking block 3, the flattening roller 4 can reduce the wear between the hose blank and the blocking block 3. At the same time, the flattening roller 4 can squeeze the hose blank to squeeze out the air inside the hose blank, so that during the storage of the hose blank, air is retained inside the hose blank, which affects the storage of the hose blank. At the same time, when the hose blank passes through the plate rack 8, the scraper plate 9 can scrape off the prepreg liquid adhering to the surface of the hose blank, thereby reducing the impact of the prepreg liquid adhering to the surface of the hose blank on the use of the finished light-curing hose.

[0063] like Figure 4 and Figure 6As shown, a light shielding plate 10 is provided between the second fixing frame 7 and the prepreg tank; the light shielding plate 10 is provided at the corner position corresponding to the prepreg body 1; the light shielding plate 10 is designed to be arc-shaped and inclined upward; a guide cone is provided at the bottom position of the light shielding plate 10, and the tip of the guide cone is arranged to face downward; when working, before the hose blank is led out through the second fixing frame 7, the light shielding plate 10 can scrape off the prepreg liquid on the surface of the hose blank, so that less residual prepreg liquid can be left on the surface of the hose blank. The removed prepreg liquid can drip through the guide cone at the bottom of the light shielding plate 10, so that the prepreg liquid can drip into the interior of the prepreg tank, reducing the waste of the prepreg liquid. At the same time, the light shielding plate 10 can block the light of the UV lamp, effectively preventing the light of the UV lamp from irradiating on the scraper plate 9, causing the residual prepreg liquid on the scraper plate 9 to solidify. At the same time, the light shielding plate 10 can effectively prevent the prepreg liquid on the prepreg tank and the scraper plate 9 from splashing onto the surface of the UV lamp, affecting the irradiation effect of the UV lamp.

[0064] like Figure 6 As shown, a bevel gear set 11 is installed inside the prepreg body 1; a rotating rod 12 is rotatably connected to the side wall of the input wheel of the bevel gear set 11; a threaded rod 13 is slidably connected inside the prepreg body 1; the end of the threaded rod 13 is rotatably connected to the inside of the second fixed frame 7; the threaded rod 13 is threadedly connected inside the output wheel of the bevel gear set 11; during operation, due to different prepreg liquids, the light curing speeds under the UV light are inconsistent, so it is necessary to adjust the light intensity of the UV lamp. When the light intensity of the UV lamp needs to be adjusted, the rotating rod 12 can be rotated so that the rotating rod 12 drives the bevel gear set 11 to rotate, and then the threaded rod 13 can be matched with the thread of the bevel gear set 11, so that the height of the second fixed frame 7 can be adjusted, so that the light intensity of the UV lamp can be changed, and then the light curing speed of the prepreg liquid on the surface of the hose blank can be adjusted, so that the thickening effect of the prepreg liquid can be better.

[0065] like Figure 6 and Fig. 9As shown, the light baffle 10 is slidably connected to the outside of the prepreg body 1; a spring is fixed between the light baffle 10 and the side wall of the prepreg body 1; a pull rope 14 is connected between the end of the light baffle 10 and the bottom of the second fixing frame 7; during operation, when the second fixing frame 7 is raised upward, the second fixing frame 7 can pull the light baffle 10 through the pull rope 14, thereby shortening the distance between the light baffle 10 and the prepreg body 1, thereby making the angle between the hose blank and the light baffle 10 larger, thereby making the contact area between the hose blank and the light baffle 10 smaller, and reducing the wear between the hose blank and the light baffle 10; when the second fixing frame 7 is lowered downward, the spring will push the light baffle 10 out, thereby increasing the distance between the light baffle 10 and the prepreg body 1, thereby making the shielding effect of the light baffle 10 better.

[0066] like Figure 7 and Figure 8 As shown, the plate frame 8 is fixed inside the prepreg body 1 through a fixing frame; the plate frame 8 does not contact the side wall of the prepreg body 1; the prepreg body 1 is rotatably connected to a rotating shaft 15; a plurality of knocking rods 16 are regularly arranged in a ring shape on the side wall of the rotating shaft 15; a synchronous belt 17 is connected between the rotating shaft 15 and the rotating shaft of the second clamping roller 6 closest to it; a knocking plate 18 is fixedly connected to the side wall of the plate frame 8; the knocking rod 16 and the knocking plate 18 are arranged correspondingly; when working, when the hose blank is in contact with the second During the process of the clamping roller 6 contacting and then driving the second clamping roller 6 to rotate, the second clamping roller 6 can drive the rotating shaft 15 to rotate through the synchronous belt 17, so that the rotating shaft 15 can drive the knocking rod 16 to rotate and knock on the knocked plate 18, so that the inside of the plate frame 8 can vibrate, and then the vibration will be transmitted to the inside of the hose blank inside the plate frame 8, so that the pre-impregnation liquid on the surface of the hose blank and the surface of the scraper plate 9 can be shaken off, so that the surface of the hose blank and the surface of the scraper plate 9 can be made cleaner, and the pre-impregnation liquid can be recycled.

[0067] like Figure 7 As shown, a plurality of convex strips are fixedly connected to the side wall of the first clamping roller 5 in an annular regularity; a plurality of grooves are opened on the side wall of the second clamping roller 6 in an annular regularity, and are arranged corresponding to the convex strips; during operation, when the first clamping roller 5 and the second clamping roller 6 clamp the hose blank, the convex strips and the grooves can increase the contact area between the hose blank and the first clamping roller 5 and the second clamping roller 6, and further increase the roughness between the hose blank and the first clamping roller 5 and the second clamping roller 6, so that the friction between the hose blank and the first clamping roller 5 and the second clamping roller 6 can make the first clamping roller 5 and the second clamping roller 6 have a better clamping effect on the hose blank, and at the same time, the increased friction can make the rotation effect of the second clamping roller 6 better, so as to effectively avoid slipping between the second clamping roller 6 and the hose blank, resulting in the second clamping roller 6 not rotating.

[0068] like Figure 8 As shown, the knocking rod 16 is designed to be arc-shaped with its tangent perpendicular to the knocked plate 18; during operation, when the knocking rod 16 knocks on the side wall of the knocked plate 18, the arc-shaped knocking rod 16 can make the knocking force stronger, thereby making the vibration generated by the knocking greater, so that the vibration cleaning effect is better.

[0069] Embodiment 2. A light-curing hose prepreg process, based on Embodiment 1, the rotating rod 12 is internally buckled with a plurality of anti-wear balls 19; the prepreg body 1 is internally provided with a rotation groove corresponding to the anti-wear balls 19; during operation, when the rotating rod 12 rotates, the anti-wear balls 19 can convert the sliding friction between the rotating rod 12 and the prepreg body 1 into rolling friction, thereby making the friction between the rotating rod 12 and the prepreg body 1 smaller, and making the wear between the rotating rod 12 and the prepreg body 1 less.

[0070] When the light-curing hose prepreg device in the above embodiment is working, when it is necessary to prepreg the hose blank, the hose blank can be passed through the interior of the first fixing frame 2, and then the hose blank can be passed through the bottom of the blocking block 3, and then the hose blank can be passed through the first clamping roller 5 and the second clamping roller 6 in sequence, and then through the interior of the plate frame 8, and led out from the interior of the second fixing frame 7, and then the prepreg liquid can be added to the interior of the prepreg tank to prepreg the hose blank, and the hose blank can be stretched by the first clamping roller 5 and the second clamping roller 6 to make the hose blank flatter, so that the prepreg effect can be better. At the same time, when the hose blank that enters later is folded When the situation occurs, the conical design of the blocking block 3 can stretch the hose blank and then enter the interior of the prepreg tank. At the same time, when the hose blank passes through the blocking block 3, the flattening roller 4 can reduce the wear between the hose blank and the blocking block 3. At the same time, the flattening roller 4 can squeeze the hose blank to squeeze out the air inside the hose blank, so that during the storage of the hose blank, air is retained inside the hose blank, which affects the storage of the hose blank. At the same time, when the hose blank passes through the plate rack 8, the scraper plate 9 can scrape off the prepreg liquid adhering to the surface of the hose blank, thereby reducing the impact of the prepreg liquid adhering to the surface of the hose blank on the use of the finished light-curing hose.

[0071] Before the hose blank is led out through the second fixing frame 7, the light baffle 10 can scrape off the prepreg on the surface of the hose blank, so that there is less residual prepreg on the surface of the hose blank, and the scraped prepreg can drip through the guide cone at the bottom of the light baffle 10, so that the prepreg can drip into the interior of the prepreg tank, reducing the waste of prepreg. At the same time, the light baffle 10 can block the light of the UV lamp, effectively preventing the light of the UV lamp from irradiating the scraper plate 9, causing the residual prepreg on the scraper plate 9 to solidify. At the same time, the light baffle 10 can effectively prevent the prepreg on the prepreg tank and the scraper plate 9 from splashing onto the surface of the UV lamp, affecting the irradiation effect of the UV lamp.

[0072] Since different prepregs have different light curing speeds when exposed to UV light, the light intensity of the UV lamp needs to be adjusted. When the light intensity of the UV lamp needs to be adjusted, the rotating rod 12 can be rotated to drive the bevel gear set 11 to rotate, so that the threaded rod 13 can be matched with the thread of the bevel gear set 11, so that the height of the second fixed frame 7 can be adjusted, so that the light intensity of the UV lamp can be changed, and the light curing speed of the prepreg on the surface of the hose blank can be adjusted, so that the thickening effect of the prepreg can be better.

[0073] When the second fixing frame 7 is raised upward, the second fixing frame 7 can pull the light baffle 10 through the pull rope 14, thereby shortening the distance between the light baffle 10 and the prepreg body 1, so that the angle between the hose blank and the light baffle 10 can be larger, so that the contact area between the hose blank and the light baffle 10 can be smaller, and the wear between the hose blank and the light baffle 10 is reduced. When the second fixing frame 7 is lowered downward, the spring will push the light baffle 10 out, thereby increasing the distance between the light baffle 10 and the prepreg body 1, so that the shielding effect of the light baffle 10 can be better.

[0074] When the hose blank contacts the second clamping roller 6 and drives the second clamping roller 6 to rotate, the second clamping roller 6 can drive the rotating shaft 15 to rotate through the synchronous belt 17, so that the rotating shaft 15 can drive the knocking rod 16 to rotate and knock on the knocked plate 18, so that the inside of the plate frame 8 can vibrate, and then the vibration will be transmitted to the inside of the hose blank inside the plate frame 8, so that the pre-impregnation liquid on the surface of the hose blank and the surface of the scraper plate 9 can be shaken off, so that the surface of the hose blank and the surface of the scraper plate 9 can be made cleaner, and the pre-impregnation liquid can be recycled.

[0075] When the first clamping roller 5 and the second clamping roller 6 clamp the hose blank, the convex strips and the grooves can increase the contact area between the hose blank and the first clamping roller 5 and the second clamping roller 6, and further increase the roughness between the hose blank and the first clamping roller 5 and the second clamping roller 6, so that the friction between the hose blank and the first clamping roller 5 and the second clamping roller 6 can make the first clamping roller 5 and the second clamping roller 6 have a better clamping effect on the hose blank, and at the same time, the increased friction can make the rotation effect of the second clamping roller 6 better, so as to effectively avoid slipping between the second clamping roller 6 and the hose blank, resulting in the second clamping roller 6 not rotating.

[0076] When the knocking rod 16 knocks on the side wall of the knocked plate 18, the arc-shaped knocking rod 16 can make the knocking force stronger, so that the vibration generated by the knocking can be greater, so that the cleaning effect of the vibration is better.
