Description

Technical Field

[0001] This utility model specifically relates to the field of die replacement technology, and more specifically to a high-speed machine die replacement mechanism. Background Technology

[0002] In modern industrial production, high-speed machines are widely used in many fields such as packaging, textiles, and papermaking. Taking the packaging industry as an example, high-speed winding machines are responsible for winding materials such as films and paper onto cores to produce various packaging rolls. In the textile industry, high-speed winding machines need to tightly and orderly wind yarns onto cores to prepare for subsequent textile processes. In these high-speed operating devices, timely and efficient replacement of cores is a key link to ensure production continuity and efficiency.

[0003] Currently, when high-speed winding machines are in operation, the traditional method for changing the core is manual. Workers need to constantly monitor the machine's operating status. Once a roll of material is wound, the used core must be quickly removed manually and a new core installed. This process is not only extremely labor-intensive, but also puts workers in a state of high tension for extended periods, making them prone to fatigue. Moreover, manual operation has limited speed. For example, in the packaging industry, changing a core manually takes about 1-2 minutes. Compared to a high-speed machine that can complete dozens of winding operations per minute, this replacement time significantly impacts overall production efficiency. Furthermore, the precision of manual operation varies from person to person. Different workers have different operating techniques and apply different amounts of force, which may result in the core not being securely installed. This can lead to problems such as core loosening and uneven material winding during high-speed operation, thus affecting product quality and increasing the defect rate.

[0004] With the development of technology, simple mechanical devices have emerged to assist in the process. A simple push-rod type tube changing device uses a mechanical push rod to eject the used tube core, after which a new tube core is manually placed, and the push rod pushes the new core core to the installation position. While this device reduces the labor intensity of workers to some extent, it still has many problems. On the one hand, its tube changing speed is still relatively slow; the reciprocating movement of the push rod and the manual intervention limit the efficiency of tube changing and cannot adapt to the high-speed operation of high-speed machines. On the other hand, the device's positioning of the tube core is not precise enough; during the ejection and installation of the tube core, core misalignment can easily occur, affecting the winding quality of the material.

[0005] A search revealed Chinese Patent Publication No. CN201720206318.4, which discloses an automatic core changing device for a coating machine's winding and unwinding. The device includes a frame and a fixed base for supporting the frame. The fixed base has a flipping support assembly and a bearing seat. The bottom of the flipping support assembly has a flipping device, which is movably connected to the fixed base via the bearing seat and the flipping device. A rotating arm is movably connected to the upper end of the frame via a bearing. One end of the rotating arm has a core shaft perpendicular to the plane of the rotating arm, and one end of the core shaft has a positioning groove. The flipping support assembly has a core support plate and a linear slide rail for supporting the core shaft, and an automatic core changing device is also provided on one side. One end of the automatic core changing device is engaged with the core shaft via the positioning groove.

[0006] Although the device in the aforementioned patent can replace the die, the machine still needs to be stopped during the replacement process because the die shaft that needs to move the die needs to be separated from the die. This greatly reduces the working efficiency of the high-speed machine and takes a long time to replace the die. Utility Model Content

[0007] The purpose of this invention is to provide a high-speed die replacement mechanism. In this device, the die is engaged with a positioning rod on a rotating disk. After the wire on the die has been used or wound up, the rotating disk is rotated by a drive assembly, causing the positioning rod on the rotating disk to work alternately. This effectively replaces the die on the positioning rod. The replaced die is then picked up and replaced by two clamping components at 90° angles, thus effectively reducing manual intervention, improving replacement efficiency, and avoiding downtime. This solves the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A high-speed machine core exchange mechanism includes a worktable; an alternation assembly is provided on the top of the worktable; the alternation assembly includes a rotating disk; multiple notches are provided on the edge of the rotating disk; a positioning rod is provided inside the notch; the bottom of the rotating disk is fixedly installed with a support shaft; the support shaft is movably installed with the top plate of the worktable via a bearing; a second helical gear is also fixedly installed at the end of the support shaft away from the rotating disk.

[0010] The workbench is equipped with a drive assembly; the drive assembly includes a first helical gear that meshes with the second helical gear; a worm gear is coaxially mounted on the first helical gear; the support rods on which the first helical gear and the worm gear are mounted are movably installed at both ends to the cross plate inside the workbench; the bottom of the worm gear is meshed with a worm; one end of the worm is fixedly installed to a reducer.

[0011] As a further technical solution of this utility model, two clamping components with the same structure are provided between the bottom of the rotary disk and the top plate of the workbench; the two clamping components are at 90°; the clamping components include a support frame; one end of the support frame is fixedly installed to the workbench, and the bottom of the other end is fixedly installed to the support leg.

[0012] As a further technical solution of this utility model, two symmetrical transverse slide rails are fixedly installed on the support frame; a transverse lead screw is provided between the two transverse slide rails; one end of the transverse lead screw is fixedly installed with the first drive motor.

[0013] As a further technical solution of this utility model, a transverse slide plate is slidably installed on the transverse slide rail; the bottom of the transverse slide plate is installed in conjunction with a transverse lead screw via an ear plate; and a rotary cylinder is fixedly installed on the transverse slide plate.

[0014] As a further technical solution of this utility model, a movable frame is fixedly installed on the rotating shaft of the rotary cylinder; a guide rod and a longitudinal lead screw are provided inside the movable frame; the guide rod and the longitudinal lead screw are installed in cooperation with a longitudinal sliding plate; the longitudinal sliding plate is slidably installed on a longitudinal slide rail fixedly installed on one side of the movable frame; and a top drive mechanism for the longitudinal lead screw is fixedly installed.

[0015] As a further technical solution of this utility model, two symmetrical insert arms are fixedly installed on the side of the longitudinal slide away from the longitudinal slide rail; the distance between the two insert arms is the same as the width of the notch.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In use, the tube core to be replaced is placed on the rotating disk. The worm gear driven by the reducer makes the worm gear and the first helical gear rotate coaxially. When the first helical gear rotates, it engages with the second helical gear at the same time, thereby effectively realizing the support shaft driving the rotating disk to rotate effectively, thereby realizing the alternation between multiple tube cores and effectively avoiding the need to stop the machine when replacing tube cores.

[0018] 2. In this utility model, after the rotating disk rotates 90°, two clamping components installed at 90° are used to unload and load the core to be replaced. During loading or unloading, the first drive motor drives the transverse screw to move the transverse slide to one side of the rotating disk, thereby effectively inserting the insertion arm on one side of the moving frame into the notch opened on the edge of the rotating disk, thus effectively reducing manual intervention. Then, the drive mechanism at the top of the longitudinal screw drives the longitudinal slide to move the insertion arm upward along the longitudinal slide rail, thereby effectively removing the core from the positioning rod. Then, the transverse screw moves backward. When it moves into place, the rotary cylinder rotates the insertion arm 180° to place the clamped core into the collection position.

[0019] 3. In this utility model, the rotating disk is rotated 90°. At this time, the positioning rod moves to the second clamping component. The second clamping component first holds the pipeline through the insertion arm, then rotates 90°. Through the rotation of the horizontal screw, it moves to the top of the positioning rod. Then, through the vertical screw, the insertion arm moves downward to make the tube core cooperate with the positioning rod. Finally, through the reversal of the horizontal screw, the insertion arm is removed from the notch opened on the edge of the rotating disk, avoiding interference with the rotation of the rotating disk.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-9 In this embodiment of the present invention, a high-speed machine core replacement mechanism includes a worktable 1; an alternation assembly 2 is provided on the top of the worktable 1; the alternation assembly 2 includes a rotating disk 20; the rotating disk 20 has multiple notches 21 on its edge; a positioning rod 22 is provided inside the notch 21; the bottom of the rotating disk 20 is fixedly installed with a support shaft 23; the support shaft 23 is movably installed with the top plate of the worktable 1 through a bearing; a second helical gear 24 is also fixedly installed at the end of the support shaft 23 away from the rotating disk 20.

[0032] The workbench 1 is equipped with a drive assembly 5; the drive assembly 5 includes a first helical gear 51 that meshes with the second helical gear 24; a worm gear 52 is coaxially arranged on the first helical gear 51; the support rods 50 on which the first helical gear 51 and the worm gear 52 are mounted are movably installed at both ends with the cross plate inside the workbench 1; the bottom of the worm gear 52 is meshed with a worm 53; one end of the worm 53 is fixedly installed with a reducer 54.

[0033] Two clamping components 3 with the same structure are provided between the bottom of the rotating disk 20 and the top plate of the workbench 1; the two clamping components 3 are at 90°; the clamping components 3 include a support frame 30; one end of the support frame 30 is fixedly installed to the workbench 1, and the bottom of the other end is fixedly installed to the support leg.

[0034] By adopting the above technical solution, when in use, the core to be replaced is placed on the rotating disk 20. The reducer 54 drives the worm gear 53 to make the turbine 52 and the first helical gear 51 rotate coaxially. When the first helical gear 51 rotates, it engages with the second helical gear 24 at the same time, thereby effectively realizing the support shaft 23 to drive the rotating disk 20 to rotate effectively, thereby realizing the alternation between multiple cores and effectively avoiding the need to stop the machine when replacing the core.

[0035] In this embodiment, two symmetrical transverse slide rails 31 are fixedly installed on the support frame 30; a transverse lead screw 34 is provided between the two transverse slide rails 31; one end of the transverse lead screw 34 is fixedly installed with the first drive motor 37.

[0036] In this embodiment, a transverse slide plate 32 is slidably mounted on the transverse slide rail 31; the bottom of the transverse slide plate 32 is installed in conjunction with the transverse lead screw 34 via an ear plate; a rotary cylinder 33 is fixedly mounted on the transverse slide plate 32.

[0037] By adopting the above technical solution, after the rotating disk 20 rotates 90°, the core to be replaced is unloaded and loaded by two clamping components 3 installed at 90°. During loading or unloading, the first drive motor 37 drives the transverse screw 34 to move the transverse slide plate 32 to one side of the rotating disk 20, thereby effectively inserting the insertion arm 310 on one side of the moving frame 36 into the notch 21 opened on the edge of the rotating disk 20. This effectively reduces manual intervention. Then, the drive mechanism at the top of the longitudinal screw 35 drives the longitudinal slide plate 39 to move the insertion arm 310 upward along the longitudinal slide rail 311, thereby effectively removing the core from the positioning rod 22. Then, the transverse screw 34 moves backward. When it moves to the position, the rotary cylinder 33 rotates the insertion arm 310 180° to place the clamped core into the collection position.

[0038] Furthermore, a movable frame 36 is fixedly mounted on the rotating shaft of the rotary cylinder 33; a guide rod 38 and a longitudinal lead screw 35 are provided inside the movable frame 36; the guide rod 38 and the longitudinal lead screw 35 are installed in conjunction with a longitudinal slide plate 39; the longitudinal slide plate 39 is slidably mounted on a longitudinal slide rail 311 fixedly mounted on one side of the movable frame 36; and a top drive mechanism for the longitudinal lead screw 35 is fixedly mounted.

[0039] In this embodiment, two symmetrical insert arms 310 are fixedly installed on the side of the longitudinal slide plate 39 away from the longitudinal slide rail 311; the distance between the two insert arms 310 is the same as the width of the notch 21.

[0040] By adopting the above technical solution, the rotating disk 20 is rotated 90°. At this time, the empty positioning rod 22 moves to the second clamping component 3. The second clamping component 3 first holds the pipeline through the insertion arm 310, and then rotates 90°. Through the rotation of the transverse screw 34, it moves to the position above the positioning rod 22. Then, through the longitudinal screw 35, the insertion arm 310 moves downward to make the tube core cooperate with the positioning rod 22. Then, through the reversal of the transverse screw 34, the insertion arm 310 is removed from the notch 21 opened on the edge of the rotating disk 20, avoiding interference with the rotation of the rotating disk 20.

[0041] The working principle of this utility model is as follows: When in use, the tube core to be replaced is placed on the rotating disk 20. The reducer 54 drives the worm gear 53 to make the turbine 52 and the first helical gear 51 rotate coaxially. When the first helical gear 51 rotates, it simultaneously engages with the second helical gear 24, thereby effectively realizing that the support shaft 23 drives the rotating disk 20 to rotate effectively, thus realizing the alternation between multiple tube cores and effectively avoiding the need to stop the machine when replacing the tube core.

[0042] After the rotating disk 20 rotates 90°, the core to be replaced is unloaded and loaded by two clamping components 3 installed at 90°. During loading or unloading, the first drive motor 37 drives the transverse screw 34 to move the transverse slide plate 32 to one side of the rotating disk 20, thereby effectively inserting the insertion arm 310 on one side of the moving frame 36 into the notch 21 opened on the edge of the rotating disk 20, thus effectively reducing manual intervention. Then, the drive mechanism at the top of the longitudinal screw 35 drives the longitudinal slide plate 39 to move the insertion arm 310 upward along the longitudinal slide rail 311, thereby effectively removing the core from the positioning rod 22. Then, the transverse screw 34 moves backward. When it moves into place, the rotary cylinder 33 rotates the insertion arm 310 180° to place the clamped core into the collection position.

[0043] Then rotate the rotating disk 20 by 90°. At this time, the empty positioning rod 22 moves to the second clamping component 3. The second clamping component 3 first holds the pipeline through the insertion arm 310, and then rotates it by 90°. Through the rotation of the transverse screw 34, it moves to the top of the positioning rod 22. Then, through the longitudinal screw 35, the insertion arm 310 moves downward to make the tube core cooperate with the positioning rod 22. Then, through the reversal of the transverse screw 34, the insertion arm 310 is removed from the notch 21 opened on the edge of the rotating disk 20 to avoid interference with the rotation of the rotating disk 20.
