Description

Technical Field

[0001] This utility model relates to the field of pipe demolding machine technology, and in particular to a fiberglass pipe demolding device. Background Technology

[0002] Fiberglass reinforced plastic (FRP) pipes are lightweight, high-strength, and corrosion-resistant non-metallic pipes. They are made by winding glass fibers with a resin matrix layer by layer onto a rotating mandrel according to process requirements, with silica sand evenly distributed between the fibers as a sand layer. Their pipe wall structure is rationally designed and advanced, fully utilizing the material's properties. While meeting strength requirements, it improves rigidity, ensuring product stability and reliability.

[0003] Chinese Patent No. CN222431315U discloses a fiberglass pipe demolding machine, including a base, a mounting frame fixedly mounted on the base, a roller rotatably connected inside the mounting frame, multiple slots provided inside the roller, each slot containing a mold, a toothed ring sleeved on the outer side of the roller, the bottom end of the toothed ring meshing with a gear, a sliding groove provided inside the base on the right side of the mounting frame, and a stop fixedly mounted on the left side of the mounting frame. This fiberglass pipe demolding machine can make full use of the waiting time during the demolding process for loading and unloading other molds and fiberglass pipes, reducing the overall demolding processing time and thus further improving demolding efficiency.

[0004] However, the above technical solution has the following shortcomings: when feeding the pipe into the demolding machine, the time interval between two consecutive demoldings needs to meet the user's filling requirements. Otherwise, during the movement of the pusher, the pusher will come into contact with the pipe and cause damage, and the pusher is likely to pinch the worker's body. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing a fiberglass pipe demolding device that automatically feeds steel pipes by setting a feeding basket at the top of the feeding rack, allowing the steel pipe to fall to a position that can abut against the feeding block, and the feeding block pushing the steel pipe onto the demolding component.

[0006] The technical solution of this utility model is a fiberglass pipe demolding device, comprising: a base plate on which a feeding rack, a demolding rack, and a discharge basket are provided; a feeding basket is provided on the feeding rack, the feeding basket including a feeding basket part and a guide rack part connected to the bottom end of the feeding basket part; the guide rack part has a pushing groove; a feeding assembly including a motor a provided on the base plate, a threaded rod provided on the output end of the motor a, a pusher threadedly connected to the threaded rod, a feeding block provided on the pusher, and a plurality of demolding rods arranged in a ring on the pusher; and a demolding assembly provided on the demolding rack.

[0007] Preferably, a rubber plate is provided on the discharge basket.

[0008] Preferably, the demolding assembly includes a rotating cylinder rotatably mounted on the demolding frame, a motor b mounted on the demolding frame, an elliptical block mounted on the output of the motor b, multiple fixed frames slidably mounted on the demolding frame, a spring mounted between the demolding frame and each of the multiple fixed frames, and a drive assembly mounted on the demolding frame; the multiple fixed frames are distributed in a ring on the demolding frame.

[0009] Preferably, the mounting bracket is connected to an expansion tube.

[0010] Preferably, the drive assembly includes a motor c mounted on the demolding frame, a gear mounted on the output end of the motor c, and a gear ring mounted on the rotating cylinder, wherein the gear and the gear ring are meshed together.

[0011] Preferably, the demolding frame is provided with multiple sets of support components distributed in a ring, and the support components include multiple rotatable rollers.

[0012] Preferably, the fixing frame is provided with an anti-slip block and an abutting block, with the elliptical block abutting against the fixing frame.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] In use, multiple steel pipes that need to be demolded are placed on the feeding basket. Under their own weight, the pipes slide downwards. The pipes slide one by one to the guide frame. Motor A drives the screw rod to rotate. The screw rod thread drives the pusher to move. The feeding block pushes the pipes onto the demolding assembly. The demolding rod, in conjunction with the demolding assembly, pushes the mold and steel pipes from the demolding assembly onto the discharge basket. When the feeding block pushes the steel pipes onto the demolding assembly, the bottom end of the next steel pipe to be fed slides into contact with the feeding block, thus tilting the bottom end of the steel pipe. During the reset process of the feeding block, the feeding block will drive the steel pipe to gradually tilt and rotate until the feeding block disengages from the steel pipe, thus achieving automatic feeding of the steel pipes.

[0020] Example 1

[0021] like Figures 1-4 As shown in this embodiment, a fiberglass pipe demolding device includes a base plate 1, a feeding basket 9, a feeding assembly, and a demolding assembly. The base plate 1 is equipped with a feeding rack 2, a demolding rack 3, and a discharge basket 4. The feeding basket 9 is mounted on the feeding rack 2 and includes a feeding basket section 91 and a guide rack section 92 connected to the bottom end of the feeding basket section 91. The guide rack section 92 has a pushing groove. The feeding assembly includes a motor a5 mounted on the base plate 1, a threaded rod mounted on the output end of the motor a5, a pusher 6 threadedly connected to the threaded rod, a feeding block 8 mounted on the pusher 6, and multiple demolding rods 7 arranged in a ring on the pusher 6. The demolding assembly is mounted on the demolding rack 3. A rubber plate is provided on the discharge basket 4. After the demolded mold and steel pipe fall into the discharge basket 4, the rubber plate absorbs the impact force of the mold falling, thereby reducing the probability of mold damage.

[0022] In this embodiment, multiple steel pipes that need to be demolded are placed on the feeding basket 9. Under their own weight, the pipes slide downwards. The multiple pipes slide one by one to the guide frame 92. The motor a5 drives the screw rod to rotate, and the screw rod thread drives the pusher 6 to move. The feeding block 8 pushes the pipes onto the demolding assembly, while the demolding rod 7, in conjunction with the demolding assembly, pushes the mold and steel pipes from the demolding assembly onto the discharge basket 4. When the feeding block 8 pushes the steel pipes onto the demolding assembly, the bottom end of the next steel pipe to be fed slides into contact with the feeding block 8, thereby making the bottom end of the steel pipe tilted. During the reset process of the feeding block 8, the feeding block 8 will drive the steel pipe to gradually tilt and rotate until the feeding block 8 disengages from the steel pipe, so that the steel pipe is automatically fed.

[0023] Example 2

[0024] like Figure 1 and Figure 3As shown, this embodiment proposes a fiberglass pipe demolding device. Compared to Embodiment 1, in this embodiment, the demolding assembly includes a rotating cylinder 10 rotatably mounted on a demolding frame 3, a motor b11 mounted on the demolding frame 3, an elliptical block 12 output from the motor b11, multiple fixed frames 16 slidably mounted on the demolding frame 3, a spring 18 positioned between the demolding frame 3 and each of the multiple fixed frames 16, and a driving assembly mounted on the demolding frame 3. The multiple fixed frames 16 are arranged in a ring on the demolding frame 3. An expansion tube 17 is connected to each fixed frame 16. The expansion tube 17 is frustoconical in shape. When the steel pipe contacts the expansion tube 17, the steel pipe is guided to the fixed frame 16 under the action of the expansion tube 17. This prevents the steel pipe from being unable to move into the expansion tube 17 after the spring 18 reduces its elasticity and the fixed frame 16 shifts position.

[0025] The fixed frame 16 is equipped with an anti-slip block, which contacts the steel pipe fixed on the fixed frame 16 to prevent the steel pipe from moving randomly. The fixed frame 16 is also equipped with an abutting block, and the elliptical block 12 abuts against the fixed frame 16. The abutting block extends a portion of the length of the rotating cylinder 10, so that the elliptical block 12 contacts the abutting block but is not contacted by the rotating cylinder 10.

[0026] In this embodiment, the motor b11 drives the elliptical block 12 to rotate, and the elliptical block 12 pushes the abutment block to move at intervals, thereby causing the fixed frame 16 to vibrate. However, the fixed frame 16 is slidably mounted on the rotating cylinder 10, and the rotating cylinder 10 restricts the vibration direction of the fixed frame 16. The spring 18 can absorb the force received by the fixed frame 16. The impact received by the fixed frame 16 will cause the fiberglass pipe and the mold mounted on it to gradually separate, improving the demolding effect of the device.

[0027] Example 3

[0028] like Figure 1 , Figure 3 and Figure 4 As shown, this embodiment of the fiberglass pipe demolding device differs from Embodiment 1 in that the driving assembly includes a motor c13 mounted on the demolding frame 3, a gear 14 mounted on the output end of the motor c13, and a gear ring 15 mounted on the rotating cylinder 10. The gear 14 and the gear ring 15 are meshed together. The demolding frame 3 is provided with multiple sets of support assemblies distributed in a ring, each support assembly including multiple rotatably mounted rollers 19.

[0029] In this embodiment, motor C13 drives gear 14 to rotate, gear 14 meshes and drives gear ring 15 to rotate, gear ring 15 drives rotating cylinder 10 to rotate, thereby adjusting according to user needs and automating the lifting device. After one end of demolding rod 7 is connected to push frame 6, the other end of demolding rod 7 will roll in contact with multiple rollers 19 to prevent demolding rod 7 from falling downward under its own weight, thus improving the service life of demolding rod 7.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
