Description

Technical Field

[0001] The present invention relates to the technical field of injection molding machines, and more specifically, it relates to a feeding device and a feeding method for winding steel fiber belts of composite pipes. Background Art

[0002] Under the background of the existing technology, the feeding methods of steel fiber belts for composite pipes mainly rely on two methods: manual material change and robot stop feeding. Due to its simple and intuitive advantages, manual material change is widely used in small-scale production. However, its high safety risks and low efficiency are particularly prominent in large-scale production environments. In contrast, the method of using a robot for stop feeding is safer, but its significant reduction in production efficiency has become the main obstacle in high-density and high-demand production environments. Therefore, neither of the existing two feeding methods is sufficient to meet the production requirements of large scale, high efficiency, and high quality.

[0003] During the production process, the monitoring of the remaining amount of the steel fiber belt is usually achieved through an alarm system or manual monitoring. This method is particularly insufficient in high-demand production environments, which may not only lead to interruptions in production continuity but also cause product quality problems. Therefore, there is an urgent need for an automated device that can effectively detect the remaining amount of the steel fiber belt and improve production efficiency and product quality.

[0004] In view of the above problems, there is still room for improvement in the existing feeding methods and remaining amount monitoring means of steel fiber belts for composite pipes in the prior art. There is an urgent need for a new solution to address the challenges of large-scale, high-efficiency, and high-quality production. The new technical solution should be able to improve feeding safety, avoid significantly reducing production efficiency, and ensure stable production conditions even in high-density production environments.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] As shown in Figure 1 and Figure 2As shown in the figure, a feeding device for winding steel fiber belts on composite pipes according to the first embodiment of the present invention includes a machine body 1. A material changing disk 2 is arranged on the machine body 1, and a plurality of material belt disks 3 are annularly distributed on the material changing disk 2. For the convenience of operation, four material belt disks 3 are adopted in this embodiment. Each material belt disk 3 is assembled by an outer disk body 304 and an inner disk body 301. A guiding cylinder 302 is connected to the inner disk body 301. A bolt column 305 is installed at the center position of the outer disk body 304 corresponding to the guiding cylinder 302. A bolt hole 3021 adapted to the bolt column 305 is further provided at the outer end of the guiding cylinder 302. A coiling rack 303 is also sleeved on the guiding cylinder 302. During use, the inner disk can be pre-fixed on the material changing disk 2 so that the end of the guiding cylinder 302 with the bolt hole 3021 faces outward. Then, the coiling rack 303 wound with the material belt is sleeved on the guiding cylinder 302 of the inner disk body 301. Next, the bolt column 305 on the outer disk body 304 is aligned with the bolt hole 3021 at the center of the guiding cylinder 302, and the bolt column 305 provided on the outer disk body 304 is aligned and screwed into the bolt hole 3021, so as to fix the outer disk and the inner disk together, and rotatably install the coiling rack 303 equipped with the material belt between the outer disk and the inner disk.

[0032] In order to facilitate the timely replacement of the material belt, it is necessary to monitor the remaining amount of the material belt in real time. For this purpose, in this embodiment, a remaining amount monitoring module 4 is arranged on the machine body 1. In this embodiment, the remaining amount monitoring module 4 includes a bracket, and a photoelectric sensor 402 is arranged on the bracket. The detection end of the photoelectric sensor 402 is aligned with the belt surface of the material belt. Specifically, when using a certain coiling rack 303 on the material changing disk 2, the material belt on the coiling rack 303 is pulled out to the winding machine. During this period, the pulled-out material belt just passes under the photoelectric sensor 402. If the photoelectric sensor 402 has been generating signals, it indicates that the remaining amount of the material belt is sufficient. If the photoelectric sensor 402 suddenly loses signals, it indicates that the remaining amount of the material belt is insufficient, and the material belt disk 3 needs to be replaced immediately. As an alternative, non-contact sensors such as ultrasonic sensors, infrared sensors, and vision sensors can be used to monitor the remaining amount of the material belt. Similarly, when using an ultrasonic sensor, an infrared sensor, or a vision sensor to monitor the remaining amount of the material belt, although the types of sensors are different, their working principles are all to accurately align the detection end with the belt surface of the material belt and monitor the moving state of the material belt in real time. Once the remaining amount of the material belt decreases, the sensor detects this point and emits a signal to trigger the operation of replacing the material belt, so as to ensure the smooth progress of production.

[0033] Different from the conventional operation, continuous transfer operations can be carried out among the respective tape reels 3 on the tape-changing tray 2, that is, the work of quickly replacing the tape reel 3 is realized. When a tape reel 3 on the tape-changing tray 2 performs a loading operation, the tape reel 3 is at the loading station at this time. When the tape on the tape reel 3 at the loading station is exhausted, the tape-changing tray 2 is driven to rotate, so that the next tape reel 3 filled with sufficient tape enters the loading station, and the previous tape reel 3 at the loading station rotates away from the loading station as the tape-changing tray 2 rotates. In this way, through the continuous transfer operation among the tape reels 3, the tape-changing efficiency and the continuity of the production line can be significantly improved. That is, when a certain tape reel 3 on the tape-changing tray 2 is performing a loading operation at the loading station, the tape reel 3 will gradually supply the installed tape into the system. Once the tape in this tape reel 3 is exhausted, the tape-changing tray 2 will be driven by its own rotational power to automatically move the next new tape reel 3 filled with tape to the loading station, and the previous tape reel 3 that has exhausted the tape will rotate away from the loading station as the tape-changing tray 2 rotates, thus realizing the working process of quickly replacing the tape reel 3, ensuring that the production line continues without a long pause, greatly improving the production efficiency and shortening the downtime.

[0034] As Figure 3 shown, a feeding device for winding a steel fiber tape on a composite pipe according to the second embodiment of the present invention is different from the first embodiment in that a tape connection module 5 is added between the tape-changing tray 2 and the remaining amount monitoring module 4 on the basis of the first embodiment. The tape connection module 5 is used to automatically feed the tape into the remaining amount monitoring module 4 and then automatically into the system after the tape reel 3 is replaced. Its working principle is: when the tape on the tape-changing tray 2 is exhausted and needs to be replaced, after replacing the new tape reel 3, the tape connection module 5 can automatically connect and guide the tape into the remaining amount monitoring module 4, so as to automatically connect the new tape into the system and ensure the continuous production of the system without manual intervention.

[0035] As Figure 4As shown, the remaining amount monitoring module 4 of this embodiment includes a material belt guide seat connected to the body 1. The material belt guide seat is a device for guiding and supporting the material belt to move stably in the device. It consists of a base 401, which is the basis of the entire material belt guide seat and is used to install and fix other components. The base 401 has an entrance and an exit. In order to facilitate the detection of the remaining amount of the material belt, a photoelectric sensor 402 is installed above the entrance of the base 401. The detection end of the photoelectric sensor 402 is just aligned with the material belt that is entering the guide seat, so as to realize rapid monitoring of the remaining amount of the material belt; secondly, the base 401 is provided with a roller group 403 at the entrance, the exit and the middle part of the base 401, that is, there are two rows of rollers, including two first rollers 403a and a third roller 403c located at the entrance and the exit, one end of the first roller 403a is installed with a first gear 404, and the two first rollers 403a are meshed with each other through the first gear 404; one end of the third roller 403c is installed with a second gear 405, and the two third rollers 403c are meshed with each other through the second gear 405, and the first roller 403a and the third roller 403c are extended out of the base 401 away from the end where the gear is installed, and then a first pulley 406 is installed; the first roller 403a and the third roller 403c are extended out of the base 401 away from the end where the gear is installed, and then a first pulley 406 is installed; the first roller 403a and the third roller 403c are extended out of the base 401 away from the end where the gear is installed; the first pulley 406 is installed at the base 4 01 The second roller 403b in the middle is arranged in an upper and lower row in a staggered manner, one end of the second roller 403b extends out from the side of the base 401 and is equipped with a third gear 408, the third gears 408 of the second rollers 403b in the upper and lower rows are meshed in sequence, that is, by rotating any third gear 408, all the second rollers 403b can rotate, and a second pulley 407 is also installed at one end of the second roller 403b near the entrance and the exit, that is, the third gear 408 and the second pulley 407 are installed on the second roller 403b at the same time, and then the two adjacent pulleys are connected by transmission, that is, the first pulley 406 of the first roller 403a at the entrance and the second pulley 407 near the second roller 403b are connected by belt a, and the first pulley 406 of the third roller 403c at the exit and the second pulley 407 near the third roller 403c are also connected by belt b. A servo motor can be installed on the side of the base 401, so that the end of the corresponding first roller 403a away from the pulley can be connected to the driving end of the servo motor, so that when the servo motor drives the corresponding first roller 403a, all the rollers can rotate, so that the first roller 403a located at the entrance can pull the material belt, and transmit it to the third roller 403c under the transmission and tightening of the second roller 403b, and extend from the third roller 403c for subsequent loading work.

[0036] Furthermore, combined with Figure 3 and Figure 4In general, adjusting rods 410 are provided at positions corresponding to the first roller 403a, the second roller 403b and the third roller 403c on the base 401, a slide groove is provided on the side of the base 401, and a slider 409 is provided in the slide groove. The first roller 403a, the second roller 403b and the third roller 403c in the upper row are rotatably connected with the sliders 409 on both sides of the base 401, and the adjusting rod 410 passes through the top of the base 401 and extends into the slide groove and is fixedly connected with the top of the slider 409. A spring is provided at the top of the adjusting rod 410 and a baffle 412 for resisting the spring is also provided at the end of the adjusting rod 410 through a bolt. In this way, by squeezing the spring to adjust the position of the slider 409, the gap between the first roller 403a, the second roller 403b and the third roller 403c in the upper row can be flexibly adjusted to meet the needs of material strips of different thicknesses, thereby improving the adaptability and flexibility of use of the equipment.

[0037] In order to avoid the situation where the material belt gets stuck or the wrong material belt needs to be removed, the present embodiment improves the base 401, and a manual material lifting mechanism is also provided on the base 401. The manual material lifting mechanism is provided on the first roller 403a at the inlet and the third roller 403c at the outlet, and includes a rotating shaft, a material lifting seat 413 and a cam 415. The two ends of the rotating shaft are rotatably connected to the material lifting seats 413 on both sides and the cam 415 is fixed to the two ends of the rotating shaft. The material lifting seat 413 is fixedly provided at the adjusting rods 410 on both sides. The material lifting seat 413 is also fixedly provided with a material lifting mechanism. The lifting piece 414 has one end which is pressed against the lifting piece 414 by the spring, and a part of the lifting piece 414 is pressed against the cam 415 by the spring. A handle 416 is also provided on the rotating shaft, and the lifting piece 414 can be lifted up through the cam 415 by turning the handle 416. The lifting piece 414 passes through the anti-top spring. Since the end of the spring is blocked by the blocking piece 412 at this time, after the lifting piece 414 is lifted up, the adjusting rod 410 is also lifted up, thereby moving the slider 409 upward in the slide groove, separating the upper and lower rows of rollers, thereby facilitating the removal of the material belt.

[0038] The working principle of the material belt guide is to transmit power to the rollers through the orderly meshing between the gears and the pulleys, so that each roller drives the material belt to move according to the predetermined trajectory and speed. During the movement of the material belt, the synergy between the rollers, pulleys and gears ensures the stability and accuracy of the material belt.

[0039] like Figure 4 As shown, the strip connection module 5 includes a connection cylinder 501 disposed on the rear end surface of the material exchange tray 2, a strip connection seat 502 connected to the output end of the connection cylinder 501, and a joint module for connecting the strip connection seat 502 and the strip guide seat; specifically, as shown in FIG. Figure 7As shown in the figure, the connecting cylinders 501 are circumferentially distributed on the rear end face of the loading tray 2. At the same time, the installation positions of the connecting cylinders 501 are adapted to the positions of the tape reels 3, so that each connecting cylinder 501 can be matched with the corresponding tape reel 3. One end of the tape connecting seat 502 is fixedly connected to the output end of the connecting cylinder 501. Two guide rollers 503 are installed in the tape connecting seat 502, and the two guide rollers 503 are arranged vertically. Guide grooves are provided on both sides of the tape connecting seat 502, and guide blocks are arranged in the guide grooves. Both ends of the upper row of guide rollers 503 are rotatably installed on the guide blocks. Two guide rods 506 are arranged on both sides of the tape connecting seat 502. One end of the guide rod 506 extends into the guide groove from the top end of the tape connecting seat 502 and is fixedly connected to the guide block. A spring is also installed on the guide rod 506. The end of the guide rod 506 is fixedly connected with a spacer 507. One end of the spring abuts against the top end of the tape connecting seat 502, and the other end abuts against the spacer 507. Then, as Figure 5 and Figure 6 shown, at the entrance of the base 401 in the tape guide seat, there are two locking pieces 417, upper and lower. The locking pieces 417 are both in the shape of an L, that is, one end of the locking piece 417 has an L-shaped locking tongue 4171. Symmetric screws 419 are also installed on the two side end faces at the entrance of the base 401. A driving motor 420 is installed on one of the symmetric screws 419. Threaded holes are provided at both ends of the locking piece 417, and the locking piece 417 is connected to the symmetric screw 419 through the threaded holes, so that the locking piece 417 and the symmetric screw 419 can be adaptively installed. When the driving motor 420 drives the symmetric screw 419 to work, the locking pieces 417 can be closed or opened synchronously. For the convenience of the tape work, the locking pieces 417 are generally located below the roller shaft. Correspondingly, a locking groove 504 is inwardly provided on the bottom surface of the tape connecting seat 502 and facing the end face of the tape guide seat. The locking groove 504 is in the shape of a horizontally placed T when viewed from the side. The connecting cylinder 501 drives the tape connecting seat 502 to approach the entrance of the tape guide seat. At this time, continue to drive the tape connecting seat 502, so that the closed locking pieces 417 can be inserted into the locking groove 504. Moreover, when the driving motor 420 is started to drive the symmetric screw 419 to work, the locking pieces 417 can be opened, so that the locking tongues 4171 on the locking pieces 417 are inserted into the T-shaped locking groove 504, realizing the relative fixation between the tape connecting seat 502 and the tape guide seat, and ensuring that the tape can stably enter the tape guide seat from the tape connecting seat 502. It should be noted that in order to ensure the normal operation of the feeding, a part of the tape needs to be extended from the tape connecting seat 502 in advance. A rotating handle 505 is also installed on one side of the tape connecting seat 502. Again, as Figure 4 shown, the rotating handle 505 is fixedly connected to one end of the lower row of guide rollers 503. When the rotating handle 505 is rotated, the tape can be led out from the tape reel 3.

[0040] Furthermore, when the new tape reel 3 is installed or the remaining amount monitoring module 4 detects that the current tape has been used up, the tape connection module 5 captures the weak feedback signal of the new tape through its own mechanical or servo control system, quickly adjusts its own position and posture, and enables the tape to accurately enter the feeding channel of the remaining amount monitoring module 4. Then, the remaining amount monitoring module 4 further verifies the remaining amount of the tape and ensures its normal operation. This process is seamlessly connected, improving the automation level and production efficiency of the system, reducing errors and downtime caused by manual operation, and ensuring the continuity and stability of production.

[0041] As Figure 8 shown, the figure is a feeding device for winding a steel fiber tape on a composite pipe according to the third embodiment of the present invention. Different from the second embodiment, a displacement module 7 for changing the position of the tape guide seat is provided on the body 1 of this embodiment. The displacement module 7 includes a Z-axis translation mechanism 702 and an X-axis translation mechanism 701. The Z-axis translation mechanism 702 includes a Z-axis guide rod 418 installed in the body 1 and a Z-axis cylinder installed at the top of the body 1. A Z-axis slide is installed on the Z-axis guide rod 418, and the output end of the Z-axis cylinder is fixedly connected to the Z-axis slide. The Z-axis slide can perform a translational movement along the Z direction by the pulling of the Z-axis cylinder; the X-axis translation mechanism 701 includes an X-axis slide seat. One end of the X-axis slide seat is fixedly connected to the side of the Z-axis slide. An X-axis lead screw is installed on the X-axis slide seat. One end of the X-axis lead screw is connected to a lead screw motor. Slide rails are provided on both sides of the X-axis slide seat. An X-axis slide adapted to the slide rails is provided on the X-axis slide seat. The tape guide seat is installed on the X-axis slide. In addition, a nut block adapted to the X-axis lead screw is fixedly installed at the bottom of the X-axis slide. By driving the X-axis lead screw by the lead screw motor, the X-axis slide can be driven to move, and then the position of the tape guide seat can be adjusted in the X-axis and Z-axis directions to adapt to the position of the tape reel 3 on the material change disk 2, and to ensure that the inlet of the tape guide seat is in the same straight line as the output end of the connection cylinder 501, thereby ensuring the reliability of tape connection.

[0042] Further, based on the above embodiments, a synchronous pulley set and a power module 6 for driving the rotation of the material changing disk 2 are also installed on the machine body 1 of the present invention. The synchronous pulley set includes the first, second, third, and fourth synchronous pulleys; a notch is formed on the machine body 1, and a first support shaft 606 is arranged on the back surface of the material changing disk 2. The first support shaft 606 extends into the machine body 1 from the notch. A support seat adapted to the first support shaft 606 is installed on the inner wall of the machine body 1, and a first synchronous pulley 601 is installed at the end of the first support shaft 606. A rotating support frame 607 is installed on the side outer surface of the machine body 1. A third synchronous pulley 603 is installed on the rotating support frame 607 through a second support shaft 608. A reduction motor 605 is also installed below the rotating support frame 607. A fourth synchronous pulley 604 is installed at the output port of the reduction motor 605. One end of the second support shaft 608 extends and a second synchronous pulley 602 is installed. The first synchronous pulley 601 is fixedly connected to the first support shaft 606, and the second synchronous pulley 602 and the third synchronous pulley 603 are simultaneously fixedly connected to the second support shaft 608; wherein, the first synchronous pulley 601 and the second synchronous pulley 602 are connected by a synchronous belt, and the third synchronous pulley 603 and the fourth synchronous pulley 604 are connected by a synchronous belt; the third synchronous pulley 603 and the fourth synchronous pulley 604 are driven to rotate by the reduction motor 605. Since the second synchronous pulley 602 and the third synchronous pulley 603 are coaxially arranged, the first synchronous pulley 601 can be driven to rotate through the second synchronous pulley 602, and then the rotating material disk is driven to rotate, completing the station change of the material tape disk 3.

[0043] In summary, the feeding device for winding the steel fiber tape of the composite pipe mainly realizes efficient and continuous feeding work through the material changing disk 2, the surplus monitoring module 4, the connection module, the displacement module 7, and the power module 6. On the material changing disk 2, the material tape disk 3 is fixedly connected through the outer disk body 304 and the inner disk body 301, and the surplus of the material tape is detected in real time by the photoelectric sensor 402, so as to achieve the effect of automatic material change. At the same time, the connection module ensures that the new material tape disk 3 can be automatically introduced into the surplus monitoring module 4 after replacement, realizing seamless transition. The displacement module 7 can adjust the position of the material tape guiding seat as needed, so that the material tape disk 3 on the material changing disk 2 can accurately enter the system, ensuring the continuity of production. The power module 6 drives the material changing disk 2 to rotate through the reduction motor 605, realizes the automatic station change of the material tape disk 3, and ensures the fast and efficient feeding ability.

[0044] Further, the present invention also provides a feeding method for the feeding device for winding the steel fiber tape of the composite pipe, and the specific steps are as follows:

[0045] S1. First, fix the coiling rack 303 with the strip on the inner disk body 301 in advance. Then, by rotating the rotary handle 505, draw out a part of the new strip from the strip reel 3 to ensure that there is enough strip length to insert between the connection cylinder 501 and the guide seat. Then, rotate and install it between the outer disk body 304 and the inner disk body 301, and fix the outer disk body 304 together with bolts;

[0046] S2. When it is detected that the remaining amount of the strip in current use is insufficient, a signal is sent by the photoelectric sensor 402 in the remaining amount monitoring module 4, and S3 is executed;

[0047] S3. Release the strip connection seat 502 that is currently engaged with the strip guide seat, that is, drive the locking piece 417 to close, and then through the connection cylinder 501, disengage the locking piece 417 from the locking groove 504. After the connection cylinder 501 is reset, S4 is executed for strip replacement;

[0048] S4. Drive the replacement disk 2 to rotate, so that the old empty strip reel 3 is disengaged from the loading station through the self-rotation of the replacement disk 2. Immediately, the new strip reel 3 enters the loading station through the self-rotation of the replacement disk 2. Correspondingly, the connection cylinder 501 drives the strip connection seat 502 to approach the entrance of the strip guide seat. Secondly, automatically adjust the position of the strip guide seat through the displacement module 7 to ensure that the output end of the connection cylinder 501 can accurately align with the strip guide seat. Then, through the drive of the connection cylinder 501, the locking piece 417 of the strip guide seat is engaged with the current locking groove 504; and the drawn-out part of the strip is smoothly transitioned into the strip guide seat through the roller shaft in the strip guide seat to complete the strip loading operation;

[0049] S5. When the strip in S4 is used up, repeat the above step S2 until all the strip reels 3 on the replacement disk 2 are exhausted. After the strip reels 3 are exhausted, repeat the above step S1, replenish the strip reels 3 and then execute step S2 to complete the cyclic loading work.

[0050] In this process, in combination with the X-axis translation mechanism 701 and the Z-axis translation mechanism 702 of the displacement module 7, the movement of the X-axis and the Z-axis can make the strip guide seat not only stay beside the replacement disk 2, but also can move to the appropriate position of the replacement disk 2, so that the strip guide seat is always vertically aligned with the connection cylinder 501, enabling the seamless docking of the conversion of the strip between the connection cylinder 501 and the strip guide seat.

[0051] Through the above steps, the entire loading process of the composite pipe steel fiber tape winding can ensure error-free automatic operation, improving production efficiency and the continuity of the production line.

[0052] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
