Description

Technical Field

[0001] This utility model relates to the field of work technology, and in particular to a plastic woven bag weaving frame. Background Technology

[0002] The main production process of woven bags involves using plastic raw materials to extrude film, cut, and unidirectionally stretch them into flat yarns, which are then woven into the product. A Chinese utility model patent, authorized publication number "CN221165350U", discloses a weaving support for processing plastic woven bags, including a base plate. Two first support plates are fixedly connected to the top of the base plate, and a winding roller is rotatably connected between the two first support plates. A drive motor corresponding to the winding roller is fixedly connected to one side of one of the first support plates, and a mounting plate is fixedly connected to the front end of the other first support plate. A fixing bolt is rotatably connected to the outside of the mounting plate, and a buckle is fixedly connected to the outer wall of the winding roller. This utility model designs a cylinder that drives a rack to move, which in turn drives a gear to reciprocate, causing a connecting rod to reciprocate and a guide ring to reciprocate, thus reciprocating the winding of the original yarn. This results in a neater and more standardized winding of the original yarn, which is beneficial for subsequent storage and use. A pulley is also designed; after the device is moved to the desired position, the pulley self-locks to stabilize the device, making it easy for workers to handle and reducing labor intensity.

[0003] The above-mentioned technical solution uses a cylinder to drive a rack to move, which in turn drives a gear to swing back and forth. This causes the connecting rod to swing back and forth along the guide ring, reciprocatingly winding the original thread. This results in a neater and more standardized winding of the original thread, which is beneficial for subsequent storage and use. However, the above-mentioned technical solution still has certain drawbacks. For example, the above equipment uses a drive motor to drive the winding roller to move stably, thereby providing driving force for winding the woven bag thread. However, when the winding roller needs maintenance and repair after long-term use, it requires workers to use special tools and multiple people to disassemble the winding roller. This increases the workload of the workers and reduces the efficiency of maintenance and repair of the winding roller. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a plastic woven bag weaving frame that can solve the problem of the equipment driving the winding roller to move stably through the drive motor, thereby providing driving force for winding the original thread of the woven bag. However, when the winding roller needs to be maintained and repaired after long-term use, it requires workers to use special tools and multiple people to disassemble the winding roller. This increases the workload of workers and reduces the efficiency of maintenance and repair of the winding roller.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a plastic woven bag weaving frame, comprising a base, a guide assembly, a cylinder, and two support frames, each of which is provided with a limit mechanism;

[0006] The limiting mechanism includes a take-up roller, two connecting seats and two limiting blocks. The two limiting blocks are rotatably connected to one side of the outer wall of the support frame. The two connecting seats are correspondingly connected to the rotating shafts on both sides of the take-up roller. A motor is fixedly installed on the outer wall of the left support frame. The outer walls of the two rotating connecting seats are each provided with a first limiting block groove. Protective shells are fixedly connected to the upper two sides of the outer walls of the two rotating connecting seats.

[0007] Among them, the inner walls of the upper two sides of the two first limiting block grooves are provided with second limiting block grooves, the interiors of the four second limiting block grooves are slidably connected with limiting blocks, the outer walls of the four protective shells are rotatably connected with rotating threaded rod sleeves, the outer walls of the upper two sides of the two connecting seats are provided with first limiting block grooves, and the interiors of the four second limiting block grooves are provided with rotating threaded rods.

[0008] Preferably, the output end of the motor extends rotatably to the outside of the left support frame and is fixedly connected to the outer wall of the rotating connecting seat, and the outer walls of the two connecting seats are respectively slidably connected to the inside of the corresponding first limiting block groove;

[0009] The outer walls of the two connecting seats and the two conical blocks are slidably connected to the two conical block grooves opened on the outer walls of the corresponding first limiting block grooves.

[0010] Preferably, the four rotating threaded rod sleeves extend rotatably into the interior of the second limiting block groove at the end closest to the protective shell;

[0011] Among them, the ends of the four limiting blocks near the first limiting block groove all slide into the interior of the first limiting block groove and are respectively slidably connected to the interior of the corresponding first limiting block groove.

[0012] Preferably, one end of each of the four rotating threaded rods near the limiting block is fixedly connected to the outer wall of the corresponding limiting block;

[0013] The ends of the four rotating threaded rods away from the limiting block are respectively connected to the internal threads of the corresponding rotating threaded rod sleeve.

[0014] Preferably, a bidirectional motor is fixedly installed inside a groove on the upper surface of the base. Both output ends of the bidirectional motor are fixedly connected to threaded rods, and the ends of the two threaded rods away from the bidirectional motor are rotatably connected to the inner wall of the groove on the upper surface of the base.

[0015] The base has a fixed guide seat fixedly connected to its upper surface. The protrusions at the lower ends of the two support frames are threadedly connected to the outer walls of the corresponding threaded rods. The outer wall of the lower support block of the guide assembly is slidably connected to the groove on the upper surface of the fixed guide seat.

[0016] Preferably, the cylinder is fixed to the outer wall of one side of the fixed guide seat, and the outer walls of the T-shaped blocks on both sides of the lower end of the two support frames are slidably connected to the two T-shaped block grooves opened on the upper surface of the base.

The output end of the cylinder extends slidably into the interior of the fixed guide seat and is fixedly connected to the outer wall of the lower support block of the guide assembly. The guide assembly consists of a support block, a support frame, and a guide ring.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This plastic woven bag weaving frame, through the rotation of the threaded rod sleeve in the limiting mechanism, causes the limiting block to slide in the second limiting block groove, so that the end of the limiting block near the first limiting block groove exits from the inside of the first limiting block groove, releasing the limiting fixation on the connecting seat. The connecting seat is no longer subject to the limiting constraint, at which point the connecting seats on both sides of the take-up roller can be pulled out from the first limiting block groove on the rotating connecting seat, and the take-up roller can be disassembled as a whole. This effectively improves the disassembly efficiency of the take-up roller, while reducing the workload of the workers, thereby improving the practicality and reliability of the equipment.

[0030] Please see Figure 1-4 This utility model provides a technical solution: a plastic woven bag weaving frame, including a base 1, a guide assembly 4, a cylinder 5 and two support frames 8;

[0031] Limiting mechanisms are installed on both support frames 8;

[0032] The limiting mechanism includes a take-up roller 6, two connecting seats 12, and two limiting blocks 16. The two limiting blocks 16 are rotatably connected to the outer wall of one side of the support frame 8. The two connecting seats 12 are correspondingly connected to the rotating shafts on both sides of the take-up roller 6. A motor 7 is fixedly installed on the outer wall of the left support frame 8. The output end of the motor 7 extends rotatably to the outside of the left support frame 8 and is fixedly connected to the outer wall of the rotating connecting seat 14. The outer walls of the two rotating connecting seats 14 are each provided with a first limiting block groove 13. The outer walls of the two connecting seats 12 are respectively slidably connected to the interior of the corresponding first limiting block groove 13. Protective shells 10 are fixedly connected to the upper two outer walls of the two rotating connecting seats 14. The upper two inner walls of the two first limiting block grooves 13 are each provided with a second limiting block groove 17. Limiting blocks 16 are slidably connected inside the four second limiting block grooves 17. The outer walls of the two connecting seats 12 have two conical blocks on the outside. The walls are slidably connected to the two conical block grooves opened on the outer wall of the corresponding first limiting block groove 13. The outer walls of the four protective shells 10 are rotatably connected to rotating threaded rod sleeves 11. The ends of the four rotating threaded rod sleeves 11 near the protective shell 10 extend rotatably into the interior of the second limiting block groove 17. The upper ends of the two connecting seats 12 are opened on the outer walls of the two sides of the first limiting block groove 13. The ends of the four limiting blocks 16 near the first limiting block groove 13 extend slidably into the interior of the first limiting block groove 13 and are slidably connected to the interior of the corresponding first limiting block groove 13. The interior of the four second limiting block grooves 17 is provided with rotating threaded rods 15. The ends of the four rotating threaded rods 15 near the limiting block 16 are fixedly connected to the outer wall of the corresponding limiting block 16. The ends of the four rotating threaded rods 15 away from the limiting block 16 are threadedly connected to the interior of the end of the corresponding rotating threaded rod sleeve 11.

[0033] The base 1 has a slot on its upper surface that houses a bidirectional motor 18. Both output ends of the bidirectional motor 18 are fixedly connected to threaded rods 9. The ends of the two threaded rods 9 furthest from the bidirectional motor 18 are rotatably connected to the inner wall of the slot on the upper surface of the base 1. A fixed guide seat 2 is fixedly connected to the upper surface of the base 1. The lower protrusions of two support frames 8 are threadedly connected to the outer walls of the corresponding threaded rods 9. The outer wall of the lower support block of the guide assembly 4 is slidably connected to the slot on the upper surface of the fixed guide seat 2. A cylinder 5 is fixed to one side of the outer wall of the fixed guide seat 2. The outer walls of the T-shaped blocks on both sides of the lower end of the two support frames 8 are slidably connected to the two T-shaped slots on the upper surface of the base 1. The upper surface of the base 1 has two T-shaped slots 3. The outer walls of the T-shaped blocks on both sides of the lower support block of the guide assembly 4 are slidably connected to the corresponding T-shaped slots 3. The output end of the cylinder 5 extends slidably into the interior of the fixed guide seat 2 and is fixedly connected to the outer wall of the lower support block of the guide assembly 4. The guide assembly 4 consists of a support block, a support frame, and a guide ring.

[0034] Furthermore, when using this device, firstly, the bidirectional motor 18 on the base 1 is started. The threaded rods 9 connected to the output ends of the bidirectional motor 18 begin to rotate. Since the lower end protrusions of the two support frames 8 are threadedly connected to the outer walls of the corresponding threaded rods 9, and the T-shaped blocks on both sides of the lower end slide correspondingly to the T-shaped block grooves opened on the upper surface of the base 1, the two support frames 8 can move relative to each other on the base 1 along the T-shaped block grooves when the threaded rods 9 rotate, thereby adjusting the spacing to accommodate take-up rollers 6 of different sizes. Then, after adjusting the spacing of the two support frames 8, the connecting seats 12 on both sides of the take-up roller 6 are aligned with the first limiting block grooves 13 on the rotating connecting seat 14 and inserted. At this time, the conical blocks on the outer walls of the connecting seats 12 and the T-shaped block grooves 13 on the outer walls of the first limiting block grooves 13 are aligned. The tapered block groove slides and provides initial positioning. Next, the rotating threaded sleeve 11 is rotated. Because the rotating threaded sleeve 11 is threadedly connected to the rotating threaded rod 15, and the rotating threaded rod 15 is fixedly connected to the limiting block 16, the rotation of the rotating threaded sleeve 11 will drive the rotating threaded rod 15 to rotate. This causes the limiting block 16 to slide within the second limiting block groove 17 until one end of the limiting block 16 near the first limiting block groove 13 slides into the interior of the first limiting block groove 13 and slides into it, thus firmly fixing the connecting seat 12 onto the rotating connecting seat 14. This completes the installation and fixing of the take-up roller 6. Then, after the motor 7 on the outer wall of the left support frame 8 starts, its output end drives the rotating connecting seat 14 to rotate, thereby driving... The winding roller 6 rotates to wind up the woven bag. During the winding process, the cylinder 5 plays a role. The cylinder 5 is fixed to the outer wall of one side of the fixed guide seat 2, and its output end is fixedly connected to the outer wall of the lower support block of the guide assembly 4. The outer wall of the lower support block of the guide assembly 4 is slidably connected to the groove on the upper surface of the fixed guide seat 2, and the T-shaped blocks on both sides slide correspondingly to the T-shaped block groove on one side of the upper surface of the base 1. By extending and retracting the output end of the cylinder 5, the guide assembly 4 can be pushed to slide on the fixed guide seat 2. The guide assembly 4 consists of a support block, a support frame, and a guide ring. The guide ring can guide the woven bag to keep it neat and orderly during the winding process. Then, when it is necessary to disassemble the winding roller 6, the threaded sleeve 11 is rotated. The threaded rod sleeve 11 is threadedly connected to the rotating threaded rod 15, and the rotating threaded rod 15 is fixedly connected to the limiting block 16. Therefore, when the threaded rod sleeve 11 is rotated, the rotating threaded rod 15 will drive the limiting block 16 to slide in the second limiting block groove 17, so that the end of the limiting block 16 near the first limiting block groove 13 exits from the inside of the first limiting block groove 13, releasing the limiting fixation on the connecting seat 12. After the limiting block 16 completely exits from the first limiting block groove 13, the connecting seat 12 is no longer subject to limiting constraint. At this time, the connecting seats 12 on both sides of the take-up roller 6 can be pulled out from the first limiting block groove 13 on the rotating connecting seat 14. The conical block on the outer wall of the connecting seat 12 disengages from the conical block groove on the outer wall of the first limiting block groove 13, and the take-up roller 6 can be disassembled as a whole.

[0035] By rotating the threaded sleeve 11 in the limiting mechanism, the threaded rod 15 will cause the limiting block 16 to slide in the second limiting block groove 17, so that the end of the limiting block 16 near the first limiting block groove 13 will exit from the inside of the first limiting block groove 13, releasing the limiting fixation on the connecting seat 12. The connecting seat 12 is no longer subject to the limiting constraint. At this time, the connecting seats 12 on both sides of the winding roller 6 can be pulled out from the first limiting block groove 13 on the rotating connecting seat 14, and the winding roller 6 can be disassembled as a whole. This effectively improves the disassembly efficiency of the winding roller 6, while reducing the workload of the workers, thereby improving the practicality and reliability of the equipment.

[0036] Structural Description: Base 1: Base 1 is the basic support component of the entire braided frame. A bidirectional motor 18 is fixedly installed inside the slot on its upper surface to drive the threaded rod 9 to rotate, thereby adjusting the distance between the two support frames 8. At the same time, a T-shaped block slot is also provided on the upper surface of base 1 to cooperate with the T-shaped block at the lower end of the support frame 8 and the guide component 4 to guide and limit their movement, ensuring the stability and accuracy of their movement.

[0037] Guide component 4: It consists of a support block, a support frame and a guide ring. T-shaped blocks are provided on both sides of the lower end of the support block, which are slidably connected to the T-shaped block groove opened on the upper surface of one side of the base 1. The outer wall of the support block is slidably connected to the groove opened on the upper surface of the fixed guide seat 2. Under the push of the cylinder 5, it can slide on the fixed guide seat 2. The support frame is used to support the guide ring, and the guide ring plays a guiding role for the woven bag, ensuring that the woven bag can be accurately wound on the winding roller 6 during the winding process.

[0038] Cylinder 5: Fixed on the outer wall of one side of the fixed guide seat 2, its output end slides into the interior of the fixed guide seat 2 and is fixedly connected to the outer wall of the lower support block of the guide assembly 4. Through the extension and retraction movement of the output end of cylinder 5, power is provided for the sliding of the guide assembly 4, thereby realizing the adjustment of the guide position of the woven bag.

[0039] Take-up roller 6: Used to take up woven bags. Connecting seats 12 are connected to the rotating shafts on both sides. When working, the take-up roller 6 rotates under the drive of the motor 7 and wraps the woven bag around its own surface.

[0040] Motor 7: It is fixedly installed on the outer wall of the left support frame 8. Its output end extends to the outside of the left support frame 8 and is fixedly connected to the outer wall of the rotating connecting seat 14. Motor 7 provides power for the rotation of the take-up roller 6. By driving the rotating connecting seat 14 to rotate, the take-up roller 6 rotates to complete the take-up operation.

[0041] Threaded rod 9: Both ends are rotatably connected to the output end of bidirectional motor 18 and the inner wall of the groove on the upper surface of base 1, respectively. It rotates under the drive of bidirectional motor 18 and realizes the relative movement of the two support frames 8 on base 1 through the threaded connection with the protrusion at the lower end of support frame 8.

[0042] Rotary connecting seat 14: The outer wall is provided with a first limiting block groove 13, which is used to cooperate with the connecting seats 12 on both sides of the winding roller 6 to realize the installation of the winding roller 6. The upper two outer walls are fixedly connected with protective shells 10. The interior of the protective shell 10 is used to install components such as rotating threaded rod sleeve 11 and rotating threaded rod 15, which play a protective role for these components.

[0043] Limiting block 16: Rotatably connected to one side of the outer wall of the support frame 8 and slides in the second limiting block groove 17. Through cooperation with the first limiting block groove 13, it limits and fixes the connecting seat 12 of the winding roller 6 to prevent the winding roller 6 from loosening or falling off during rotation.

[0044] Rotating threaded rod sleeve 11: The outer wall is rotatably connected to the protective shell 10, and the end near the protective shell 10 extends rotatably into the interior of the second limiting block groove 17, and is threadedly connected to the rotating threaded rod 15. By rotating the rotating threaded rod sleeve 11, the rotating threaded rod 15 and the limiting block 16 can be moved to realize the fixing and disassembly operation of the winding roller 6.

[0045] Rotating threaded rod 15: One end is fixedly connected to the outer wall of the limiting block 16, and the other end is internally threaded to one end of the rotating threaded rod sleeve 11. Under the drive of the rotating threaded rod sleeve 11, the limiting block 16 slides, thereby completing the function of limiting and fixing the winding roller 6.

[0046] Bidirectional motor 18: It is fixedly installed inside the slot on the upper surface of the base 1. Both output ends are fixedly connected to threaded rods 9. By rotating in both directions, it provides power to the two threaded rods 9, so that the two support frames 8 can move relative to each other or towards each other to meet the installation requirements of winding rollers 6 of different sizes.

[0047] Fixed guide seat 2: Fixed on the upper surface of the base 1, used to support the guide assembly 4 and provide a guide groove for the sliding of the guide assembly 4. At the same time, a cylinder 5 is fixedly installed on one side of its outer wall, providing an installation base and power transmission path for the movement of the guide assembly 4.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
