DETAILED DESCRIPTION

[0021] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Reference Figures 1 to 9 : A glass fiber reinforced plastic cable protection tube automatic processing device, comprising a frame 1, a molding film shell 11 horizontally mounted on the frame 1, and a mobile feeding device 12 slidably mounted on the frame 1 and moving along the axis of the molding film shell 11. The frame 1 is also provided with an outer cover shell 2 surrounding the outside of the molding film shell 11, the longitudinal section of the outer cover shell 2 is in the shape of an arc, and the outer cover shell 2 is provided with an inlet and outlet 21 (combined with the inlet and outlet 21) facing the mobile feeding device 12. Figure 1 and Figure 7 ), both ends of the outer shell 2 are blocked by side blocking panels 22 (such as Figure 6 As shown); two laminating rollers 3 are arranged in the outer cover shell 2, and the axes of the laminating rollers 3 are parallel to the forming film shell 11 and are respectively located at the upper and lower ends of the forming film shell 11, and the laminating rollers 3 move in a centering manner to laminate the surface of the forming film shell 11 to press the material wrapped on the forming film shell 11; an inner cavity 23 is arranged inside the outer cover shell 2, and a feed port 231 connected to the inner cavity 23 is arranged at the bottom of the inner wall of the outer cover shell 2, and a discharge port 232 connected to the inner cavity 23 is arranged at the top of the inner wall of the outer cover shell 2, and a conveyor belt 24 is arranged in the inner cavity 23, and the conveyor belt 24 conveys the resin entering the inner cavity 23 through the feed port 231 to the discharge port 232, and falls on the surface of the laminating roller 3 above through the discharge port 232.

[0023] When the device in the present application processes the FRP cable protection tube, the mobile feeding device 12 conveys the material wrapped with resin to the molded film shell 11, and the molded film shell 11 rotates under the drive of the motor to wind the material around the molded film shell 11 to form the FRP cable protection tube. The outer cover shell 2 in this embodiment is coaxially arranged on the outside of the molded film shell 11, and the material conveyed by the mobile feeding device 12 enters from the inlet and outlet 21 of the outer cover shell 2, and the two bonding rollers 3 installed inside the outer cover shell 2 are bonded to the surface of the molded film shell 11, and when the material is wound on the molded film shell 11, the surface of the material is bonded to the surface of the material to flatten the material. When the bonding roller 3 located below is in contact with the material wound on the surface of the molded film shell 11, the bonding roller 3 When the outer cover shell 2 is touched, the mixed resin on the material will be squeezed downward by the bonding roller 3 and the fallen resin falls on the bottom of the outer cover shell 2. An inner cavity 23 is arranged inside the outer cover shell 2. The inner cavity 23 is located at the bottom of the inner wall of the outer cover shell 2 and is provided with a feed port 231. The resin at the bottom of the outer cover shell 2 enters the inner cavity 23 through the feed port 231 under the action of gravity, and is conveyed to the top of the inner cavity 23 by the conveyor belt 24 in the inner cavity 23, and then falls on the surface of the bonding roller 3 located above through the discharge port 232 at the top of the inner cavity 23. As the bonding roller 3 contacts the surface of the material, it is mixed with the material again, thereby ensuring the content of resin in the FRP cable protection tube, thereby ensuring the strength of the subsequent FRP cable protection tube after curing.

[0024] In order to achieve the purpose that the conveyor belt 24 can convey the resin entering the inner cavity 23 to the top discharge port 232, the following features are specifically set: The outer housing 2 is located at the upper and lower ends of the inner cavity 23 and is rotatably mounted with a driving roller 25, the axis of which is parallel to the axis of the outer housing 2, and the driving roller 25 is sleeved on both ends of the conveyor belt 24, and the conveyor belt 24 is provided with a plurality of push plates 241 (such as Figure 5 As shown in the figure, one end of the push plate 241 away from the conveyor belt 24 is in contact with the inner wall of the inner cavity 23, and a rotating driver 26 for driving the driving roller 25 to rotate is arranged outside the outer cover shell 2.

[0025] The upper and lower ends of the inner cavity 23 of the outer cover shell 2 are rotatably installed with driving rollers 25, and the driving rollers 25 are sleeved on the two ends of the conveyor belt 24. When the rotary driver 26 is started, the driving rollers 25 can be driven to rotate. The rotation of the driving rollers 25 drives the conveyor belt 24 to rotate in the inner cavity 23. The push plate 241 arranged on the outside of the conveyor belt 24 is in contact with the inner wall of the inner cavity 23. When the resin accumulates at the bottom of the inner cavity 23, it will enter between two adjacent push plates 241. When the conveyor belt 24 rotates, the resin between the two adjacent push plates 241 moves with the push plates 241 in the closed space, so that the resin can be transferred from the bottom of the inner cavity 23 to the top of the inner cavity 23. After the push plate 241 carries the resin to the top of the inner cavity 23, the push plate 241 releases the resin. Under the action of gravity, the resin flows into the top of the inner cavity 23 along the inclined push plate 241 and falls onto the bonding roller 3 through the discharge port 232. The rotary driver 26 in this embodiment can be a servo motor.

[0026] In order to solve the problem of how to ensure that the push plate 241 fits the inner wall of the inner cavity 23 when the conveyor belt 24 moves in the arc-shaped inner cavity 23, the following features are specifically set: The inner cavity 23 is located inside the conveyor belt 24 and is provided with an inner support block 233. The inner support block 233 fits the inner side of the conveyor belt 24. The inner support block 233 is provided with mounting grooves 234 on both sides thereof that fit the conveyor belt 24. The inner support block 233 is located in the mounting grooves 234 and is provided with a plurality of rollers 235 that fit the inner side of the conveyor belt 24.

[0027] The inner support block 233 inside the inner cavity 23 in this embodiment supports the inside of the conveyor belt 24, so that the conveyor belt 24 has the same curvature as the inner cavity 23, so that the distance between the surface of the conveyor belt 24 and the inner wall of the inner cavity 23 is kept the same during the movement of the conveyor belt 24, so as to ensure that when the push plate 241 on the conveyor belt 24 moves in close contact with the inner wall of the inner cavity 23, a closed space can be formed between two adjacent push plates 241 to ensure that the resin therein will not leak during the movement. Rollers 235 are arranged in the mounting grooves 234 on both sides of the inner support block 233. The rollers 235 can reduce the friction between the conveyor belt 24 and the conveyor belt 24, so that the conveyor belt 24 moves more smoothly.

[0028] In order to achieve the purpose of the rotary driver 26 driving the driving roller 25 to rotate, the following features are specifically provided: One end of the driving roller 25 located at the top is inserted into the side blocking panel 22 and extends to the outside of the outer cover shell 2. The end of the driving roller 25 located outside the outer cover shell 2 is coaxially provided with a first synchronous wheel 251 (combined with Figure 7 and Figure 8 The rotary driver 26 is fixedly mounted on the top of the outer cover shell 2, the rotary axis of the rotary driver 26 is arranged parallel to the axis of the driving roller 25, and a second synchronous wheel 261 is coaxially mounted on the working end of the rotary driver 26, and the second synchronous wheel 261 and the first synchronous wheel 251 are connected through a synchronous belt 262.

[0029] In this embodiment, the driving roller 25 located at the top passes through the side blocking panel 22 and extends to the outside of the outer cover shell 2 and is coaxially connected to the first synchronous wheel 251. The second synchronous wheel 261 at the working end of the rotary driver 26 is connected to the first synchronous wheel 251 through a synchronous belt 262. Therefore, the rotary driver 26 can drive the driving roller 25 in the inner cavity 23 to rotate outside the outer cover shell 2, so that the conveyor belt 24 transports the resin at the bottom of the inner cavity 23 to the top.

[0030] In order to solve the problem of how to ensure that the resin can accurately fall from the discharge port 232 onto the surface of the upper laminating roller 3, the following features are specifically set: The two ends of the laminating roller 3 are inserted into the waist-shaped holes 221 provided on the side blocking panel 22, and the waist-shaped holes 221 extend in the vertical direction along the axis perpendicular to the outer cover shell 2. The part of the laminating roller 3 located outside the side blocking panel 22 is inserted into the movable seat 31, and the movable seat 31 is provided with a limit block 311 inserted into the waist-shaped hole 221; the limit block 311 of the movable seat 31 located above is installed with a collection box 32, and the collection box 32 has an opening with an upwardly increasing width (such as Figure 5 As shown in the figure, a discharge port 321 is provided at the bottom of the collecting box 32, and the discharge port 321 is located above the laminating roller 3.

[0031] The bottom of the collecting box 32 is provided with an inclined surface 322 inclined toward the discharge port 321, and the discharge port 321 is located at the lower end of the inclined surface 322; an inclined guide plate 236 is provided on the side of the discharge port 232 away from the conveyor belt 24, and the guide plate 236 guides the resin conveyed by the conveyor belt 24 to flow above the opening of the collecting box 32; the outer cover shell 2 is provided with a bottom baffle 211 (such as Figure 3 and Figure 8 As shown in FIG. 1 ), the bottom baffle 211 extends toward the interior of the outer cover shell 2.

[0032] The two ends of the bonding roller 3 in this embodiment are inserted into the moving seat 31, and the moving seat 31 is slidably installed on the waist-shaped hole 221 of the side blocking panel 22 through the limit block 311 to maintain the movement in the vertical direction. A collecting box 32 is also arranged between the limit blocks 311 of the two upper moving seats 31. The collecting box 32 opens upward and is located below the discharge port 232. After passing through the discharge port 232, the resin falls vertically under the action of gravity. No matter at any height of the bonding roller 3, the resin will eventually fall into the collecting box 32 and move toward the discharge port 321 along the inclined surface 322 at the bottom of the collecting box 32. The resin can fall on the surface of the bonding roller 3 through the discharge port 321 and be mixed with the material again as the bonding roller 3 contacts the material. In this embodiment, a guide plate 236 is provided on the side of the discharge port 232 away from the conveyor belt 24. The guide plate 236 ensures that the resin thrown out by the conveyor belt 24 flows toward the top of the collection box 32. In this embodiment, a bottom baffle 211 is provided at the bottom of the outer cover shell 2 located at the inlet and outlet 21. The bottom baffle 211 ensures that the resin can only fall into the inner part of the outer cover shell 2 and flow to the feed port 231 at the bottom of the inner cavity 23.

[0033] In order to solve the problem of how to ensure that the laminating roller 3 always keeps in contact with the material wound on the forming film shell 11 during the processing of the glass fiber reinforced plastic cable protection tube, the following features are specifically set: At least two vertically extending guide rods 312 are provided on the side of the moving seat 31 away from the axis of the outer cover shell 2. The moving seat 31 is inserted on the slide 313 through the guide rods 312. The slide 313 is arranged at one end of the moving seat 31 away from the axis of the outer cover shell 2; a spring 314 is sleeved on the guide rod 312, and the spring 314 elastically connects the moving seat 31 and the slide 313; the slide 313 is connected to the working end of the synchronous moving unit 33, and the synchronous moving unit 33 drives the upper and lower slides 313 to move synchronously in opposite directions along the waist-shaped hole 221.

[0034] The synchronous moving unit 33 includes two racks 331 respectively arranged at the same end of the two slides 313. The racks 331 on the upper and lower slides 313 are parallel to each other and are respectively meshed with driving gears 332 rotatably mounted on the side blocking panel 22. The axis of the driving gear 332 is parallel to the axis of the outer cover shell 2; the synchronous moving unit 33 also includes a first linear drive 333 fixedly mounted on the side blocking panel 22. The working end of the first linear drive 333 is arranged to move in the vertical direction, and the working end of the first linear drive 333 is fixedly connected to one of the slides 313.

[0035] The movable seat 31 in this embodiment is inserted on the slide 313 through the guide rod 312, and is elastically connected to the slide 313 through the spring 314. When the synchronous moving unit 33 drives the slide 313 to move toward the molded film shell 11, the laminating roller 3 is laminated with the surface of the molded film shell 11, and then the position of the slide 313 is fixed. The movable seat 31 can move with the increase of the material thickness to compress the spring 314 to ensure the pressure of the laminating roller 3 on the material. The upper and lower slides 313 are respectively connected to the two racks 331 of the synchronous moving unit 33, and the driving gear 332 is meshed with the two racks 331 to achieve the synchronous opposite movement of the two slides 313. When the first linear drive 333 drives one of the slides 313 to move in the vertical direction, the other slide 313 moves accordingly. The first linear drive 333 in this embodiment can be a linear cylinder or an electric push rod, etc. The first linear drive 333 can change the position of the slide 313 and the laminating roller 3, and keep the position of the slide 313 unchanged.

[0036] In order to facilitate demoulding of the glass fiber reinforced plastic cable protection tube on the molded membrane shell 11 after processing, the following features are specifically set: A second linear drive 13 is disposed on the frame 1 . The working end of the second linear drive 13 is fixedly connected to the outer cover shell 2 . The second linear drive 13 drives the outer cover shell 2 to move in a horizontal direction perpendicular to the axis of the molding film shell 11 .

[0037] The outer cover shell 2 in this embodiment is installed at the working end of the second linear drive 13. The second linear drive 13 can be a slide or other equipment. The second linear drive 13 drives the outer cover shell 2 to move in a horizontal direction perpendicular to the axis of the molding film shell 11. Therefore, after the material is completely wrapped around the molding film shell 11 to form a glass fiber reinforced plastic cable protection tube, the second linear drive 13 starts to drive the outer cover shell 2 away from the molding film shell 11, and the molding film shell 11 is moved out of the inlet and outlet 21 of the outer cover shell 2, thereby facilitating the curing of the glass fiber reinforced plastic cable protection tube and the subsequent demolding.

[0038] In order to achieve the purpose that the molded film shell 11 can be separated from the outer cover shell 2 and the outer cover shell 2 remains on the same straight line with the axis of the molded film shell 11 after being reset, the following features are specifically set: The side blocking panel 22 is provided with a positioning opening 222 extending in the horizontal direction. When the positioning opening 222 is attached to the outer wall of the molded film shell 11, the axis of the outer cover shell 2 and the molded film shell 11 are in the same straight line; the width of the inlet and outlet 21 is greater than the diameter of the molded film shell 11; the diameter of the inlet and outlet 21 of the outer cover shell 2 in this embodiment is greater than the diameter of the molded film shell 11, so it can be ensured that the molded film shell 11 passes through the inlet and outlet 21, and the outer cover shell 2 moves in the horizontal direction. When the outer cover shell 2 moves toward the molded film shell 11, the molded film shell 11 enters the interior of the outer cover shell 2 and enters the positioning opening 222 of the side blocking panel 22. The width of the positioning opening 222 is the same as the diameter of the molded film shell 11. Therefore, when the top axis of the positioning opening 222 is in the same straight line with the axis of the molded film shell 11, the position of the outer cover shell 2 can be limited to ensure that the outer cover shell 2 and the molded film shell 11 are in the same straight line.

[0039] Working principle: When processing the FRP cable protection tube, the mobile feeding device 12 conveys the material wrapped with resin to the molded film shell 11. The molded film shell 11 rotates under the drive of the motor, and the material is wound on the molded film shell 11 to form the FRP cable protection tube. The material conveyed by the mobile feeding device 12 enters from the inlet and outlet 21 of the outer cover shell 2. The two laminating rollers 3 installed inside the outer cover shell 2 are laminated to the surface of the molded film shell 11, and when the material is wrapped around the molded film shell 11, the surface of the material is laminated to flatten the material. When the laminating roller 3 located below contacts the material wrapped on the surface of the molded film shell 11, the resin mixed on the material will be squeezed downward by the laminating roller 3. The resin falls to the bottom of the outer cover shell 2, and the resin at the bottom of the outer cover shell 2 enters the inner cavity 23 through the feed port 231 under the action of gravity, and is conveyed to the top of the inner cavity 23 by the conveyor belt 24 in the inner cavity 23, and then falls on the surface of the bonding roller 3 located above through the discharge port 232 at the top of the inner cavity 23. As the bonding roller 3 contacts the surface of the material, it is mixed with the material again. After the material is completely wrapped around the molding film shell 11 to form a FRP cable protection tube, the second linear drive 13 starts to drive the outer cover shell 2 away from the molding film shell 11, and the molding film shell 11 is removed from the inlet and outlet 21 of the outer cover shell 2, and the FRP cable protection tube is cured and subsequently demolded.

[0040] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
