Description

Technical Field

[0001] This application relates to the field of reinforced bag production technology, and in particular to an automatic feeding structure for reinforced bag sheets. Background Technology

[0002] As a common product, reinforced bundles have wide applications in industrial production and daily life. With the continuous development of the manufacturing industry, the requirements for the production efficiency and quality of reinforced bundles are also increasing. The production of reinforced bundles involves multiple stages, among which the feeding of the reinforcing strips and the bonding of the film are key steps. The ease and efficiency of these steps directly affect the overall production efficiency and quality of the reinforced bundles. Improving the automation level and ease of operation of the reinforcing strip feeding process is of great significance for promoting the development of the reinforced bundle manufacturing industry.

[0003] Currently, in the production process of reinforcing slabs, the sheet film raw materials are usually conveyed in three layers: upper, middle, and lower. Reinforcing strips need to be placed between two adjacent sheets along the height direction. In the past, the common practice for feeding reinforcing strips was to rely on manual operation by workers. Workers had to twist their bodies and stick their heads into the space between the upper and middle sheets or between the middle and lower sheets to place the reinforcing strips, and then push the reinforcing strips horizontally to the designated middle position. However, this feeding method not only involves frequent movements and makes the workers' working posture and condition very uncomfortable, but it is also very inconvenient to operate, resulting in low production efficiency and high labor intensity for workers. Summary of the Invention

[0004] In order to reduce the labor intensity of workers and increase the feeding speed of reinforcing bars, this application provides an automatic feeding structure for reinforcing bar wrapping sheets.

[0005] The automatic feeding structure for the reinforcing bar wrapping sheet provided in this application adopts the following technical solution: The automatic feeding structure for reinforcing bar wrapping sheets includes: frame; A rib conveying mechanism is provided on the frame and is used to move the rib from the outside to the inside of the frame and convey it between two adjacent upper and lower films. A pressing mechanism, disposed on the frame, is used to press the film and the ribs together; The rib conveying mechanism includes: A support beam is fixed to the frame and is arranged along the film conveying direction; A conveyor is mounted on the supporting crossbeam; Two positioning and mounting components for positioning and installing the reinforcing ribs are fixed on the conveyor belt of the conveyor.

[0006] By adopting the above technical solution, the reinforcing sheet conveying mechanism can move the reinforcing sheets from the outside to the inside of the frame and convey them between two adjacent film sheets. Two positioning and mounting components are fixed on the conveyor belt of the conveyor, which can be used for positioning and installing the reinforcing sheets. After the reinforcing sheet is installed on the positioning and mounting components, the conveyor starts and drives the positioning and mounting components and the reinforcing sheet to be conveyed to the designated position between the two adjacent film sheets, realizing the automatic feeding process of the reinforcing sheets. Subsequently, the pressing mechanism presses the film and one end of the reinforcing sheet together and performs subsequent thermal bonding between the two to ensure the stability of the bond between the reinforcing sheet and the film. After the reinforcing sheet is fixed to the film, the conveyor reverses its rotation and drives the positioning and mounting components to move to the outside of the frame. As in the traditional method, the operator does not need to reach into the narrow space to operate, but can conveniently install the reinforcing sheet again on the outside of the frame, avoiding uncomfortable postures during feeding, reducing the difficulty and labor intensity of manual operation, and at the same time, a robotic arm can be used to automatically install the reinforcing sheets, improving the installation efficiency of the reinforcing sheets and realizing the automation of the feeding of reinforcing sheet bundles.

[0007] Optionally, the rib conveying mechanism further includes a movable adjustment frame disposed between the support beam and the conveyor, wherein the frame of the conveyor is fixed to the movable adjustment frame; the support beam and the movable adjustment frame are fixed together by connecting bolts.

[0008] By adopting the above technical solution, the movable adjustment frame is fixed to the frame of the conveyor and then to the support beam through connecting bolts. When it is necessary to adapt to the production of ribbed bags of different sizes, the required position and length of the ribs will also be different due to the different sizes of the ribbed bags. By loosening the connecting bolts, the installation positions of the conveyor, positioning and mounting components, and ribs can be adjusted so that the ribs are accurately placed in the appropriate positions, thereby meeting the needs of different ribbed bag production, improving the versatility and applicability of the equipment, avoiding the problem of frequent equipment replacement or complex adjustments due to changes in the size of the ribbed bags, and reducing production costs.

[0009] Optionally, the supporting beam has multiple waist-shaped adjustment slots along its length, and the connecting bolt passes through the waist-shaped adjustment slots and is threaded with a locking nut.

[0010] By adopting the above technical solution, when it is necessary to adjust the installation position of the rib, the locking nut is loosened. At this time, the connecting bolt can move within the waist-shaped adjustment groove, thereby driving the moving adjustment frame and the conveyor to move, realizing the adjustment of the rib installation position. Thus, the installation position of the rib can be flexibly adjusted according to the length of the rib and the production needs of different sizes of rib bags, meeting diverse production requirements. Furthermore, during the adjustment process, the waist-shaped adjustment groove provides a certain amount of room for the connecting bolt, facilitating fine adjustment, greatly improving the error tolerance of the equipment loading, and ensuring the accuracy and flexibility of the rib installation position.

[0011] Optionally, the movable adjustment frame includes a connecting rod fixed to the conveyor frame and two adjusting legs fixed below the connecting rod. The two adjusting legs abut against both sides of the support beam. A friction block for increasing the contact area between the adjusting legs and the support beam is also fixed on the side of the support beam. A friction pad is laid on the side of the friction block that abuts against the support beam.

[0012] By adopting the above technical solution, the two adjustable legs are fixed below the connecting rod and respectively abut against both sides of the support beam. The friction block on the side of the adjustable leg abutting against the support beam increases the contact area between the two, and the friction pad laid on the side of the friction block abutting against the support beam further enhances the friction. After the movable adjustment frame is locked on the support beam by connecting bolts and locking nuts, the adjustable legs are less likely to shift due to vibration during equipment operation, ensuring the stability of the conveyor, positioning and installation components and the position of the rib plate, and improving the accuracy of rib plate conveying and installation.

[0013] Optionally, the positioning and mounting component includes: The lower support plate assembly is fixed to the conveyor belt of the conveyor. An upper pressure plate is spaced above the lower support plate assembly and is fixed to the lower support plate assembly on one side; The lower support plate assembly and the upper pressure plate form a positioning cavity for accommodating the reinforcing ribs.

[0014] By adopting the above technical solution, a positioning chamber is formed between the lower support plate group and the upper pressure plate spaced above the lower support plate group. When the rib needs to be installed, it can be placed in the positioning chamber to achieve the positioning and initial fixation of the rib. When the conveyor is running, it can drive the positioning and installation components to move together with the rib, accurately transporting the rib to the designated installation position between two adjacent films, and keeping the rib stable during the conveying process, avoiding the rib from shifting or falling off during the conveying, and improving the accuracy and stability of the rib installation.

[0015] Optionally, the length of the lower support plate assembly is longer than the length of the upper pressure plate.

[0016] By adopting the above technical solution, when positioning and installing the ribs, the lower support plate group is longer than the upper pressure plate, which can provide a larger support area and make the ribs more stable. When the conveyor drives the positioning and installation components and the ribs to be transported between two adjacent films, the longer lower support plate group can better support the ribs, so that the ribs will not shift or fall off during the transportation process.

[0017] Optionally, the lower support plate assembly includes: Two symmetrically arranged fixing plates are fixed to the conveyor belt of the conveyor. An extension plate is disposed between the two fixed plates and is slidably connected to the fixed plates; One of the fixed plates is threaded with a locking bolt, and a plurality of locking holes are evenly spaced along the length of one side of the extension plate, with the end of the locking bolt inserted into the locking hole.

[0018] By adopting the above technical solution, when it is necessary to adapt to the production of ribbed bags of different sizes, the locking bolt can be turned to disengage it from the locking hole of the extension plate. At this time, the extension plate can slide relative to the fixed plate, and the length of the lower support plate group can be adjusted. After adjusting to the appropriate length, the locking bolt can be inserted into the corresponding locking hole to fix the extension plate. This allows the length of the lower support plate group to be flexibly adapted according to the length of the ribs, improving the equipment's versatility for the production of ribbed bags of different sizes and reducing production costs.

[0019] Optionally, the upper pressure plate is fixed with an inclined upward guide plate on the side away from the side where it is fixed to the lower support plate assembly.

[0020] By adopting the above technical solution, the upwardly inclined guide plate can play a guiding role during the installation of the ribs. When the ribs are installed into the positioning chamber, the guide plate can guide the ribs into the positioning chamber between the lower support plate group and the upper pressure plate, avoiding the ribs from shifting or getting stuck during the installation process, making the installation of the ribs smoother and more accurate, thereby improving the installation efficiency of the ribs.

[0021] Optionally, the clamping mechanism includes: Two rotating shafts are provided in parallel and distributed vertically along the height direction. The two rotating shafts respectively abut against the sides of the upper film and the lower film that are far apart from each other. The swing arm is rotatably connected to the frame at its middle position. One end of the swing arm is hinged to the rotating shaft, and the other end is equipped with a drive cylinder. The housing of the drive cylinder is hinged to the frame, and the piston rod is hinged to the swing arm.

[0022] By adopting the above technical solution, when the piston rod of the drive cylinder extends or retracts, it will drive the swing arm to swing around the middle position where it is rotatably connected to the frame. The swing of the swing arm will then drive the rotating shaft that is hinged to it to move. Since the two rotating shafts are respectively abutted on the sides of the upper and lower film that are far apart from each other, the movement of the rotating shafts can flexibly perform the pressing operation on the upper and lower film, so as to achieve a tight fit between the film and the rib. Compared with the traditional vertical pressing method of upper and lower cylinders, the structure of the rotating shaft, swing arm and drive cylinder creates an operating space in the middle position, which can better accommodate the conveyor, positioning and installation components and other equipment, allowing operators to perform related loading operations more conveniently.

[0023] Optionally, a limit switch is fixed on the frame of the conveyor.

[0024] By adopting the above technical solution, when the positioning and installation component moves with the conveyor belt, the limit switch can monitor its position in real time. When the positioning and installation component moves to the preset travel position, the limit switch will send a signal to control the conveyor belt to stop running, thus preventing the positioning and installation component from moving excessively. At the same time, the limit switch can prevent the positioning and installation component from exceeding the normal movement range, reduce manual intervention, and improve the installation efficiency and safety of the rib plate.

[0025] In summary, this application includes at least one of the following beneficial technical effects: The conveyor of the rib conveying mechanism can drive the positioning and installation components and ribs to a designated position between adjacent film sheets. After the ribs are fixed to the film, the conveyor runs in reverse and drives the positioning and installation components to move to the outside of the frame. This allows the operator to reinstall the ribs more conveniently on the outside of the frame, avoiding the inconvenience of workers having to twist their bodies and reach between the film sheets to put the material in the traditional way, and greatly improving the installation efficiency of the ribs. The support beam is fixed to the movable adjustment frame by connecting bolts. Multiple waist-shaped adjustment slots are opened on the support beam. With the help of locking nuts, the connecting bolts can move in the waist-shaped adjustment slots when the locking nuts are loosened. This allows for quick changes in the installation positions of the conveyor, positioning and mounting components, and ribs. This enables the production of rib bags of different sizes to be adapted according to the length of the ribs, and also allows for fine adjustment of the installation position of the ribs. When there are deviations in the installation position, timely adjustments can be made to improve the fault tolerance rate of the equipment. When it is necessary to adapt to the production of ribbed bags of different sizes, the locking bolt can be turned to disengage it from the locking hole of the extension plate. At this time, the extension plate can slide relative to the fixed plate to adjust the length of the lower support plate assembly. After adjusting to the appropriate length, the locking bolt is inserted into the corresponding locking hole to fix the extension plate. This allows the length of the lower support plate assembly to be flexibly adapted to the length of the ribs. With the fine adjustment of the waist-shaped adjustment groove, connecting bolts and movable adjustment frame, the equipment can be improved to improve its versatility for the production of ribbed bags of different sizes and reduce production costs. Compared to the traditional vertical pressing method using upper and lower cylinders, the clamping mechanism, through the structure of a rotating shaft combined with a swing arm and a drive cylinder, creates operating space in the middle position, thus better accommodating equipment such as conveyors and positioning installation components, allowing operators to perform related material loading operations more conveniently.

[0028] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0029] This application discloses an automatic feeding structure for reinforcing bar wrapping sheets. (Refer to...) Figures 1-3 The automatic feeding structure for the reinforcing strips of the tie-up bundle includes a frame 1, a strip conveying mechanism 2, and a pressing mechanism 3. The strip conveying mechanism 2 and the pressing mechanism 3 are both located on the frame 1. The strip conveying mechanism 2 is used to move the strips 4 from the outside to the inside of the frame 1 and convey them between two adjacent film sheets 5. The pressing mechanism 3 is used to press the film sheets 5 and the strips 4 together. Through the cooperation of the strip conveying mechanism 2 and the pressing mechanism 3, the automatic feeding of the strips 4 and the pressing operation with the film sheets 5 are realized, which improves the efficiency and automation of the feeding of the strips 4 in the production process of the tie-up bundle, and avoids the inconvenience and low efficiency of manual operation.

[0030] Specifically, refer to Figures 3-5The rib sheet conveying mechanism 2 includes a supporting beam 21 and a conveyor 22. The supporting beam 21 is fixed to the frame 1 and is arranged along the conveying direction of the film 5. The conveyor 22 is mounted on the supporting beam 21. The conveyor 22 can be a belt conveyor. The conveyor belt of the conveyor 22 is driven by a motor to rotate the drive rollers. When the motor is running, power is transmitted to the drive rollers, and the rotation of the drive rollers drives the conveyor belt to move, thus conveying the rib sheet 4. Two positioning and mounting components 23 are fixed on the conveyor belt of the conveyor 22 for positioning and mounting the rib sheet 4. The function of the positioning and mounting components 23 is to accurately position the rib sheet 4 so that it can be smoothly conveyed to the designated position. After the rib sheet 4 is placed in the positioning and mounting components 23, it moves synchronously with the movement of the conveyor belt, ensuring the stability and accuracy of the conveying process.

[0031] Reference Figure 4 and Figure 5 The rib sheet conveying mechanism 2 also includes a movable adjustment frame 24 disposed between the support beam 21 and the conveyor 22. The frame of the conveyor 22 is fixed to the movable adjustment frame 24, and the support beam 21 and the movable adjustment frame 24 are fixed together by connecting bolts 25. The installation positions of the conveyor 22, the positioning and mounting assembly 23, and the rib sheet 4 can be changed by the connecting bolts 25, so as to adapt to the production of different sizes of rib bags according to the length of the rib sheet 4, thereby improving the versatility of the equipment. The support beam 21 has multiple waist-shaped adjustment grooves 211 along its length, and the connecting bolts 25 pass through the waist-shaped adjustment grooves 211 and are threaded with locking nuts. When different sizes of rib bags need to be produced, the connecting bolt 25 can be moved freely in the waist-shaped adjustment groove 211 by loosening the locking nut. This allows for quick adjustment of the positions of the connecting bolt 25, the movable adjustment frame 24, and the conveyor 22, thereby finely adjusting the installation position of the rib plate 4. After adjusting to the appropriate position, the connecting bolt 25 is tightened to complete the position adjustment. The operation is simple and quick, and it also improves the error tolerance of the equipment feeding.

[0032] Reference Figure 4 and Figure 5 The movable adjustment frame 24 includes a connecting rod 241 fixed to the frame of the conveyor 22, and two adjusting legs 242 fixed below the connecting rod 241. The two adjusting legs 242 respectively abut against both sides of the supporting beam 21. The adjusting legs 242 are made of square steel pipes. A friction block 243 is fixed on the side of the adjusting leg 242 that abuts against the supporting beam 21 to increase the contact area between the two. A friction pad is laid on the side of the friction block 243 that abuts against the supporting beam 21. The friction pad can further increase the friction force and prevent the adjusting leg 242 from shifting. After the connecting bolt 25 and the locking nut lock the adjusting leg 242 in position, the friction force provided by the friction block 243 and the friction pad makes the adjusting leg 242 less susceptible to displacement due to vibration and other factors, ensuring the stability of the conveying of the reinforcing sheet 4.

[0033] Reference Figures 4-6 The positioning and mounting assembly 23 includes a lower support plate assembly 231 and an upper pressure plate 232. The lower support plate assembly 231 is fixed to the conveyor belt of the conveyor 22. The lower support plate assembly 231 is made of aluminum alloy plate, which has a light weight and good surface flatness. The upper pressure plate 232 is spaced above the lower support plate assembly 231 and fixed to the lower support plate assembly 231 on one side. A positioning chamber for accommodating the reinforcing rib 4 is formed between the lower support plate assembly 231 and the upper pressure plate 232. The reinforcing rib 4 is placed in the positioning chamber and moves with the conveyor 22. The positioning chamber provides a stable placement space for the reinforcing rib 4, ensuring that the reinforcing rib 4 will not shake or fall during the conveying process, thus ensuring the accuracy of the conveying. The length of the lower support plate assembly 231 is longer than the length of the upper pressure plate 232, which gives the reinforcing rib 4 a better support and positioning effect in the positioning chamber, preventing the reinforcing rib 4 from shifting during the conveying process. When the reinforcing plate 4 is placed in the positioning chamber, the longer part of the lower support plate assembly 231 can better support the reinforcing plate 4, keeping it stable and preventing the reinforcing plate 4 from shifting position due to factors such as vibration during the conveying process.

[0034] Reference Figures 4-6 The lower support plate assembly 231 includes two symmetrically arranged fixed plates 2311 and an extension plate 2312 disposed between the two fixed plates 2311. The fixed plates 2311 are fixed to the conveyor belt of the conveyor 22 by bolts. The extension plate 2312 is slidably connected to the fixed plates 2311, and the extension plate 2312 slides with the fixed plates 2311 by means of a slider and a groove. One of the fixed plates 2311 is threaded with a locking bolt 2313, and the extension plate 2312 has a plurality of locking holes 2314 evenly spaced along its length on one side, and the end of the locking bolt 2313 is inserted into the locking hole 2314. When it is necessary to adapt to ribs 4 of different lengths, loosen the locking bolt 2313, slide the extension plate 2312 between the fixed plates 2311 to the appropriate position, insert the locking bolt 2313 into the corresponding locking hole 2314, and tighten the locking bolt 2313. This will allow the length of the lower support plate group 231 to be adjusted, thus adapting to the production of rib bags of different sizes. The adjustment method is simple and reliable and can meet a variety of production needs.

[0035] An upwardly inclined guide plate 233 is fixed to the side of the upper pressure plate 232 away from its fixation to the lower support plate assembly 231. The function of the guide plate 233 is to facilitate the guiding installation of the rib 4. When the rib 4 is placed into the positioning and installation assembly 23, the guide plate 233 can guide the rib 4 smoothly into the positioning chamber, improving the installation efficiency of the rib 4. During the placement process, the rib 4 only needs to overlap the guide plate 233, and it can easily slide into the positioning chamber along the tilt angle of the guide plate 233, without the need for precise manual alignment, making the operation more convenient.

[0036] Limit switches are fixed on the frame of conveyor 22. The limit switches can be photoelectric switches or electromagnetic switches. When a photoelectric switch is used, the position of the object is detected by emitting and receiving light. When the positioning mounting component 23 blocks the light, a signal is immediately sent. The limit switches are used to limit the movement of the positioning mounting component 23. When the positioning mounting component 23 moves to the designated position, the limit switch sends a signal to control the conveyor 22 to stop running, so as to ensure that the rib 4 can accurately reach the designated position between the two adjacent films 5.

[0037] Reference Figure 2 and Figure 7 The pressing mechanism 3 includes a rotating shaft 31 and a swing arm 32. Two rotating shafts 31 are arranged parallel to each other and distributed vertically along the height direction. The two rotating shafts 31 respectively abut against the sides of the upper and lower film 5 that are far apart from each other. The surfaces of the rotating shafts 31 need to be polished to reduce friction with the film 5. The middle position of the swing arm 32 is rotatably connected to the frame 1, and the swing arm 32 can swing around the rotation point. One end of the swing arm 32 is hinged to the rotating shaft 31, and the other end is equipped with a drive cylinder 33. The housing of the drive cylinder 33 is hinged to the frame 1, and the piston rod is hinged to the swing arm 32. When the piston rod of the drive cylinder 33 extends, it pushes the swing arm 32 to swing around the rotation point, causing the rotating shaft 31 to approach and press against the film 5 and the reinforcing rib 4; when the piston rod retracts, the rotating shaft 31 moves away from the film 5. The pressing mechanism 3 changes the traditional vertical pressing method of the upper and lower cylinders. It achieves upper and lower pressing by rotating the middle shaft, leaving operating space in the middle gap to better accommodate equipment such as the conveyor 22 and the positioning and installation component 23, allowing operators to perform related feeding operations more conveniently, such as adjusting the position of the film 5.

[0038] The implementation principle of the automatic feeding structure for the reinforcing bar wrap according to the embodiment of this application is as follows: In the production process of the reinforcing bar wrap, the reinforcing bar conveying mechanism 2 is first adjusted according to the length of the reinforcing bar 4. During the adjustment, the connecting bolt 25 can be loosened, and the connecting bolt 25 and the moving adjustment frame 24 can be moved in the waist-shaped adjustment groove 211 of the support beam 21 to make a preliminary adjustment to the installation position of the reinforcing bar 4. At the same time, the locking bolt 2313 on the fixing plate 2311 of the lower support plate group 231 is loosened, the extension plate 2312 is slid, and the length of the lower support plate group 231 is adjusted to match the length of the reinforcing bar 4. Then the locking bolt 2313 and the connecting bolt 25 are tightened. Then, the reinforcing sheet 4 is placed in the positioning chamber of the positioning and mounting assembly 23. Guided by the guide plate 233, the reinforcing sheet 4 can smoothly enter. When the conveyor 22 is started, the conveyor belt moves, causing the positioning and mounting assembly 23 and the reinforcing sheet 4 to move from the outside to the inside of the frame 1. When the positioning and mounting assembly 23 moves to the position of the limit switch, the limit switch detects and sends a signal, controlling the conveyor 22 to stop. At this time, the reinforcing sheet 4 accurately reaches the designated position between two adjacent sheets 5. Then, the drive cylinder 33 of the pressing mechanism 3 is activated, the piston rod extends and pushes the swing arm 32 to swing, so that the rotating shaft 31 presses the sheet 5 and the reinforcing sheet 4 together. After the sheet 5 and the reinforcing sheet 4 complete the hot bonding, the piston rod of the drive cylinder 33 retracts, the rotating shaft 31 moves away, the conveyor 22 reverses, and the positioning and mounting assembly 23 returns to the outside of the frame 1, ready for the next feeding. The whole process realizes the automation of the feeding of the reinforcing sheet 4, avoiding the inconvenience and inefficiency of manual operation, and improving the efficiency and quality of the reinforcing sheet production. The movable adjustment frame 24 and the adjustable lower support plate assembly 231 can be adapted to the production of rib bags of different sizes, improving the versatility of the equipment; and the pressing mechanism 3 has an operating space in the middle position between the upper film 5 and the lower film 5, so as to better accommodate the conveyor 22, the positioning and installation assembly 23 and other equipment, allowing operators to perform related material loading operations more conveniently.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
