Description

Technical Field

[0001] This utility model relates to the field of glass fiber tube production technology, and in particular to a glass fiber tube unloading mechanism. Background Technology

[0002] Existing fiberglass tube production lines typically employ a continuous production process. First, resin-impregnated fiberglass bundles are shaped into tube blanks through winding or pultrusion. These blanks are then fed into a heat curing zone. Under high temperature, the resin fully cross-links, forming a fiberglass tube with specific rigidity. After curing, the fiberglass tube moves forward at a constant speed under the action of a traction device. After online length cutting, it leaves the production line via a feeding device and falls into a discharge frame, then proceeds to subsequent processes such as trimming, visual inspection, and packaging.

[0003] During the traction and cutting process, after the fiberglass tube leaves the curing mold, it is typically gripped and continuously pulled out by at least two alternating tracked traction machines to ensure that the tube remains taut and moves in a straight line. When the fiberglass tube reaches the set length, the cutting mechanism starts and moves synchronously with the fiberglass tube to complete the cutting operation. After cutting, the cutting mechanism quickly resets, ready to enter the next work cycle.

[0004] However, before the fiberglass tube enters the unloading frame and is cut, it is suspended in mid-air. This suspension negatively impacts the unloading process. The suspended tube, due to its own weight, is prone to bending and deformation, affecting its dimensional accuracy and compromising its quality. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a glass fiber tube unloading mechanism that can reduce the bending deformation of the glass fiber tube and ensure the dimensional accuracy and quality of the glass fiber tube.

[0006] To solve the above-mentioned technical problems, the present invention provides a glass fiber tube unloading mechanism, including a receiving frame, multiple support arms arranged at intervals in the receiving frame to support the lower side of the glass fiber tube, a lifting device for driving the multiple support arms to move up and down, and a collection frame arranged on the right side of the receiving frame. The bottom surface of the receiving frame is inclined downward from left to right and has multiple one-to-one clearance openings for the multiple support arms to pass through. The right side of the receiving frame has a guide opening for the glass fiber tube on the bottom surface of the receiving frame to pass through and fall into the collection frame.

[0007] As an improvement to the above solution, the support arm extends to the left and right.

[0008] As an improvement to the above solution, the upper side of the support arm is provided with a V-shaped groove for supporting the lower side of the glass fiber tube.

[0009] As an improvement to the above solution, the lifting device includes multiple lifting cylinders and multiple connecting vertical rods that are installed one-to-one at the output end of the lifting cylinders. The multiple connecting vertical rods are used to pass through multiple clearance openings one-to-one and are fixedly connected to the lower side of multiple support arms one-to-one.

[0010] As an improvement to the above solution, the height of the connecting vertical rod is greater than the height of the material guide opening.

[0011] As an improvement to the above solution, the left end of the upper opening of the material collection frame is lower than the lower end of the material guide opening, and the right end of the upper opening of the material collection frame is higher than the upper end of the material guide opening.

[0012] As an improvement to the above solution, the lower part of the collection frame is rotatably connected to multiple rollers arranged at intervals.

[0013] As an improvement to the above solution, soft pads are attached to both the left and right sides of the material collection frame.

[0014] Implementing this utility model has the following beneficial effects: The glass fiber tube unloading mechanism of this utility model uses a receiving frame, a support arm, a lifting device and a collection frame to cooperate with each other. Before the glass fiber tube is cut off, multiple support arms are set at intervals to support the glass fiber tube, so that the glass fiber tube is not completely suspended in the air, which can reduce the bending deformation of the glass fiber tube and ensure the dimensional accuracy and quality of the glass fiber tube.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] like Figures 1 to 4As shown, a glass fiber tube unloading mechanism in this embodiment of the present invention includes a receiving frame 100, multiple support arms 200 arranged at intervals in the receiving frame 100 for supporting the lower side of the glass fiber tube, a lifting device 300 for driving the multiple support arms 200 to move up and down, and a collection frame 400 arranged on the right side of the receiving frame 100. In fact, both the receiving frame 100 and the collecting frame 400 are provided with slots that open upwards and extend through the front and rear sides, so that the glass fiber tubes can fall smoothly into the receiving frame 100 or the collecting frame 400 after cutting. They also allow operators to remove the glass fiber tubes from the front and rear sides of the receiving frame 100 or the collecting frame 400. The lifting device 300 can be a single device used to drive multiple support arms 200 to move up and down, or multiple devices such as cylinders, hydraulic cylinders, or single-axis translation tables used to drive multiple support arms 200 to move up and down, so that the support arms 200 can cut between the upper and lower positions.

[0022] The receiving frame 100 has a bottom surface that slopes downwards from left to right and is provided with multiple one-to-one clearance openings 110 for multiple support arms 200 to pass through. The right side of the receiving frame 100 has a guide opening 120 for the glass fiber tube on the inner bottom surface of the receiving frame to pass through and fall into the collecting frame 400. In practice, the outline of the clearance opening 110 should be larger than the outline of the support arm 200, so that the support arm 200 can move downwards through the clearance opening 110 to below the inner bottom surface of the receiving frame 100 or upwards through the clearance opening 110 to above the inner bottom surface of the receiving frame 100. Similarly, the outline of the guide opening 120 should be larger than the outline of the cut glass fiber tube, ensuring that the glass fiber tube can pass through the guide opening 120 and fall into the collecting frame 400.

[0023] It should be noted that the distance between two adjacent support arms 200 is determined by the length and strength of the fiberglass tube. Shortening the distance between two adjacent support arms 200 can reduce the deformation of the fiberglass tube. The specific distance is set according to actual production needs, and will not be elaborated here.

[0024] The specific working principle of the fiberglass tube unloading mechanism of this utility model is as follows: In the initial state, the multiple support arms 200 are in the lower position. When a fiberglass tube enters the inner bottom surface of the receiving frame 100, the lifting device 300 moves the multiple support arms 200 to the upper position. Figure 3As shown, the upper side of the support arm 200 supports the lower side of the fiberglass tube, preventing the fiberglass tubes above the bottom surface of the receiving frame 100 from being suspended in mid-air, reducing bending deformation of the fiberglass tubes, and ensuring the dimensional accuracy and quality of the fiberglass tubes. After the fiberglass tubes are cut, the lifting device 300 moves multiple support arms 200 to the lower position. The multiple support arms 200 pass through multiple clearance openings 110 one by one and move below the bottom surface of the receiving frame 100. Under the obstruction of the bottom surface of the receiving frame 100, as... Figure 4 As shown, the fiberglass tube is transferred to the bottom surface of the receiving frame 100. Under its own weight and the guiding action of the bottom surface of the receiving frame 100 being inclined from left to right, the fiberglass tube rolls down and passes through the guide port 120 before falling into the collection frame 400, completing the unloading of the fiberglass tube and entering the next working cycle.

[0025] The glass fiber tube unloading mechanism of this utility model uses a receiving frame 100, a support arm 200, a lifting device 300 and a collection frame 400 to cooperate with each other. Before the glass fiber tube is cut off, multiple support arms 200 are set at intervals to support the glass fiber tube, so that the glass fiber tube is not completely suspended in the air, which can reduce the bending deformation of the glass fiber tube and ensure the dimensional accuracy and quality of the glass fiber tube.

[0026] Specifically, the support arm 200 is preferably extended to the left and right, matching the front and rear extension direction of the glass fiber tube, so as to provide sufficient support area for the glass fiber tube to support it.

[0027] More specifically, the upper side of the support arm 200 is preferably provided with a V-shaped groove 210 for supporting the lower side of the glass fiber tube. In fact, the V-shaped groove 210 is centered with the glass fiber tube leaving the production line, which can prevent the glass fiber tube from rolling left and right compared with the upper side of the support arm 200 which is provided with a single inclined surface.

[0028] It is worth mentioning that the lifting device 300 preferably includes multiple lifting cylinders 310 and multiple connecting vertical rods 320, each corresponding to one of the output ends of the lifting cylinders 310. The multiple connecting vertical rods 320 are used to pass through multiple clearance openings 110 and are fixedly connected to the lower sides of the multiple support arms 200. In fact, the multiple lifting cylinders 310 can drive the multiple support arms 200 to move synchronously, ensuring that all support arms 200 can rise or fall simultaneously when needed, thereby maintaining stable support for the fiberglass tube. Preferably, according to the output speed of the fiberglass tube, the multiple lifting cylinders 310 can operate sequentially from front to back. This sequential operation is better because it can more accurately match the movement state of the fiberglass tube. Specifically, when the fiberglass tube is output from the production line at a certain speed, the sequentially operating lifting cylinders 310 can adjust the height of the support arms 200 one by one according to the real-time position of the tube, avoiding instantaneous impact or positional deviation that may be caused by synchronous action, reducing the shaking or deformation of the fiberglass tube caused by uncoordinated action of the support arms 200, thereby improving the smoothness of supporting the fiberglass tube.

[0029] It should be noted that the movement control of the multiple lifting cylinders 310 can be controlled manually, or it can be equipped with control components such as PLC or central control computer to control the automatic operation of the multiple lifting cylinders 310.

[0030] Preferably, the height of the connecting vertical rod 320 is greater than the height of the material guide opening 120, ensuring that the connecting vertical rod 320 has enough space to move vertically during the lifting and lowering process, so that when the support arm 200 is in the upper position, its upper side is higher than the upper end of the material guide opening 120 and when the support arm 200 is in the lower position, its lower side is higher than the lower end of the material guide opening 120, so that the glass fiber tube can be transferred to the inner bottom surface of the receiving frame 100.

[0031] Specifically, the left end of the upper opening of the collection frame 400 is preferably lower than the lower end of the guide opening 120, and the right end of the upper opening of the collection frame 400 is preferably higher than the upper end of the guide opening 120. When the glass fiber tube is output from the guide opening 120, the lower left end of the collection frame 400 opening facilitates the entry of the tube and reduces the risk of tube collision or jamming due to height difference; while the higher right end opening ensures that the tube can slide smoothly into the collection frame 400 after entering the frame, avoiding the tube from sliding out or accumulating at the frame opening due to the opening being too low, thus ensuring the efficiency and reliability of tube collection.

[0032] Furthermore, the lower part of the collection frame 400 is preferably rotatably connected to multiple rollers 410 arranged at intervals. When the operator removes the glass fiber tube supported by the rollers 410 from the front and rear sides of the collection frame 400, the rolling of the rollers 410 can effectively reduce the friction between the tube and the collection frame 400, and reduce scratches or wear on the tube surface caused by friction.

[0033] Furthermore, soft pads 420 are preferably attached to both the left and right sides of the collection frame 400. When the glass fiber tube enters the collection frame 400 or moves within the frame, the soft pads 420 can effectively absorb the kinetic energy of the tube, preventing the tube from directly colliding with the rigid sidewall, thereby reducing scratches, wear, or deformation on the tube surface caused by the collision.

[0034] The above are merely specific embodiments of this utility model and do not limit the patent scope of this utility model. Although embodiments of this utility model have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the claims and their equivalents. Those skilled in the art can make various other corresponding changes and modifications based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model.
