[0001] This utility model relates to the technical field of yarn tube paper production equipment, and in particular to a yarn tube paper return and feeding device. Background Technology

[0002] In the production of yarn tube paper, defective products from the production process need to be re-rolled and reused. Currently, due to the difficulty of unbundling these defective products, the current method involves manually cutting the rolled yarn tube paper along its outer axial direction using a utility knife. The cut pieces are then manually fed into a pulping machine for pulping. This method results in high labor intensity for workers. Therefore, our workshop technicians, based on the actual on-site conditions, have proposed this yarn tube paper re-rolling and feeding device. Utility Model Content

[0003] The purpose of this invention is to provide a paper tube return and feeding device to realize the automatic unbundling and feeding of rolled paper tubes, thereby reducing the labor intensity of workers.

[0004] To achieve the above objectives, this utility model provides a paper return and feeding device for yarn tubes, including a tray with a central hole. The lower end of a lifting tube is aligned with and fixed to the central hole of the tray. A lifting lug is installed on the upper end of the lifting tube. A geared motor is installed on the lower side of the tray, extending into the lifting tube. The output shaft of the geared motor extends downward out of the tray. The output shaft of the geared motor is connected to one end of a connecting rod, and the other end of the connecting rod extends radially to the outside of the tray. The end of the connecting rod located on the outside of the tray is connected to an upright rod, which is located on the upper side of the tray.

[0005] The upper end of the hanging pipe is provided with a wiring hole. One end of the wire is electrically connected to the geared motor, and the other end extends a certain distance through the wiring hole.

[0006] A central ring is fixed to the lower side of the tray, the central hole of the tray is located inside the central ring, and multiple reinforcing plates are fixed to the outer wall of the central ring in a radial pattern.

[0007] A thickened plate is fixedly installed on the bottom of the pallet inside the central ring. The thickened plate has a clearance hole corresponding to the center hole of the pallet. The reduction motor passes through the clearance hole on the thickened plate and then extends into the lifting pipe. The reduction motor is installed on the thickened plate.

[0008] A connector is fixedly installed on the output shaft of the geared motor; the top of the connector is provided with a connecting hole, which is fixedly sleeved on the output shaft of the geared motor; the lower end of the connector is provided with a transverse through hole; the end of the connecting rod connected to the output shaft of the geared motor is provided with a screw section, and after the screw section passes through the through hole, a nut is screwed on.

[0009] The outer edge of the tray is circular, and a rotating ring is rotatably mounted on the outer edge of the tray. The upright is fixedly mounted on the rotating ring, and a drive plate is fixedly connected to the lower side of the rotating ring. The connecting rod is located at one end on the outer side of the tray and is connected to the drive plate.

[0010] The outer edge of the tray is provided with a first annular groove, and the side of the rotating ring facing the tray is provided with a second annular groove. At least three support wheels are rotatably installed in the second annular groove or the first annular groove by at least three pins, and the support wheels extend into the first annular groove or the second annular groove.

[0011] A support ring is fixed to the lower side of the tray. The cross-section of the support ring is "L" shaped, and the first annular groove is formed between the outer side of the support ring and the lower side of the tray.

[0012] The drive plate is provided with a sliding hole, through which the connecting rod passes.

[0013] There are two uprights, with a gap between them.

[0014] Compared with the prior art, this utility model has the following technical effects:

[0015] 1. The tray of this utility model is used to support the yarn tube paper, the lifting tube is used to pass through the central paper tube of the yarn tube paper, and the lifting lug is used to connect to the hook of the lifting equipment to lift the yarn tube paper. The geared motor drives the connecting rod to rotate, which in turn drives the upright to rotate. The upright is used to control the speed at which the paper on the yarn tube paper unwinds. When the geared motor starts, the upright begins to rotate around the tray and the yarn tube paper. The rotation direction of the upright is the same as the unwinding direction of the paper, thereby controlling the unbundling speed of the paper. When it is necessary to stop the paper from unbundling, the geared motor is turned off, and the upright blocks the paper, preventing the paper from unbundling automatically. This realizes the automatic unbundling and feeding of the rolled yarn tube paper, thereby reducing the labor intensity of workers.

[0016] 2. The outer edge of the tray of this utility model is circular, and a rotating ring is rotatably installed on the outer edge of the tray. The upright is fixedly installed on the rotating ring, and a drive plate is fixedly connected to the lower side of the rotating ring. One end of the connecting rod located on the outside of the tray is connected to the drive plate to improve the stability of the upright and prevent the connecting rod from bending.

[0017] 3. The drive plate of this utility model is provided with a sliding hole, through which the connecting rod passes. When the output shaft of the geared motor is in an eccentric state, the connecting rod will not be blocked when rotating.

[0018] 4. This utility model is equipped with two uprights to improve the stability of unbundling. When the diameter of the yarn tube paper becomes smaller, the paper can be pushed out through the upright on the inner side. Attached Figure Description

[0036] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0037] Example 1:

[0038] Please see Figure 1-7 A paper return and feeding device for yarn tubes includes a tray 10 with a central hole. The lower end of a lifting tube 30 is aligned with and fixed to the central hole of the tray 10. A lifting lug 40 is installed on the upper end of the lifting tube 30. A geared motor 60 is installed on the lower side of the tray 10. The geared motor 60 extends into the lifting tube 30. The output shaft of the geared motor 60 extends downward out of the tray 10. The output shaft of the geared motor 60 is connected to one end of a connecting rod 70. The other end of the connecting rod 70 extends radially to the outside of the tray 10. The end of the connecting rod 70 located on the outside of the tray 10 is connected to a vertical rod 50 located on the upper side of the tray 10.

[0039] The tray 10 is used to support the yarn tube paper 80, the lifting tube 30 is used to pass through the central paper tube of the yarn tube paper 80, the lifting lug 40 is used to connect to the hook of the lifting equipment so as to lift the yarn tube paper 80, the reduction motor 60 drives the connecting rod 70 to rotate, thereby driving the upright 50 to rotate through the connecting rod 70, and the upright 50 is used to control the speed at which the paper 81 on the yarn tube paper 80 spreads out.

[0040] The yarn tube 80 is initially placed horizontally on the ground. In use, the lifting pipe 30 of the paper-laying device is moved horizontally past the center paper tube of the yarn tube 80. Then, the hook of the lifting equipment is hooked onto the lifting lug 40, and the lifting equipment is used to lift the yarn tube 80. Figure 7 The state is shown. After pulling the paper 81 a certain distance, the yarn tube paper 80 is lifted above the pulping equipment. Due to the gravity of the paper 81, there is a tendency for the paper 81 to unbundle from the yarn tube paper 80. However, the paper 81 is blocked by the upright 50, and the paper 81 will not automatically unbundle during the hoisting process. When the reduction motor 60 is started, the upright 50 begins to rotate around the tray 10 and the yarn tube paper 80. The rotation direction of the upright 50 is the same as the unbundling direction of the paper 81. In this embodiment, the paper 81 is located between the upright 50 and the yarn tube paper 80, thereby controlling the unbundling speed of the paper 81. When it is necessary for the paper 81 to stop unbundling, the reduction motor 60 is turned off, and the upright 50 blocks the paper 81, so that the paper 81 will not automatically unbundle. This realizes the automatic unbundling and feeding of the rolled yarn tube paper 80, thereby reducing the labor intensity of workers.

[0041] In this embodiment, see Figure 3 , 7 The upper end of the hanging pipe 30 is provided with a wiring hole 31. One end of the wire is electrically connected to the geared motor 60, and the other end extends a certain distance through the wiring hole 31. In use, the end of the wire extending out of the wiring hole 31 is connected to the power cord.

[0042] When it is necessary to note, please refer to Figure 7The power cord connection must not affect the rotation of the upright 50 or the unbundling of the paper 81. Simultaneously, the hook of the lifting equipment can be restricted and fixed to prevent it from rotating, thus preventing the paper tube 80 from rotating during unbundling and the power cord from becoming tangled.

[0043] Example 2:

[0044] Based on Example 1, see Figure 2 , 4 A central ring 12 is welded to the lower side of the pallet 10. The central hole of the pallet 10 is located inside the central ring 12. Multiple reinforcing plates 11 are radially welded to the outer wall of the central ring 12. By installing the central ring 12 and the reinforcing plates 11, the overall weight of the pallet 10 is reduced while ensuring the structural strength of the pallet 10.

[0045] Furthermore, for ease of installation of the geared motor 60, see [reference needed]. Figure 4 A thickened plate 14 is fixedly installed on the bottom of the pallet 10 inside the center ring 12. The thickened plate 14 is provided with a clearance hole corresponding to the center hole of the pallet 10. The geared motor 60 passes through the clearance hole on the thickened plate 14 and then extends into the lifting pipe 30. The geared motor 60 is installed on the thickened plate 14.

[0046] In this embodiment, the geared motor 60 is a small constant speed brake motor.

[0047] Specifically, see Figure 4 A connector 61 is fixedly mounted on the output shaft of the geared motor 60. The top of the connector 61 has a connecting hole 62, which is fixedly fitted onto the output shaft of the geared motor 60. The lower end of the connector 61 has a transverse through hole 63. A threaded section 71 is provided at the end of the connecting rod 70 that connects to the output shaft of the geared motor 60. After passing through the through hole 63, a nut 72 is screwed onto the threaded section 71. The connector 61 facilitates the connection between the output shaft of the geared motor 60 and the connecting rod 70.

[0048] During installation, the connecting hole 62 at the top of the connector 61 is mounted on the output shaft of the geared motor 60 by means of a key pair and an interference fit.

[0049] Example 3:

[0050] Based on Example 1 or Example 2, see Figure 1 , 2 The outer edge of the tray 10 is circular, and a rotating ring 20 is rotatably mounted on the outer edge of the tray 10. The upright 50 is fixedly mounted on the rotating ring 20. A drive plate 25 is fixedly connected to the lower side of the rotating ring 20. One end of the connecting rod 70 located on the outer side of the tray 10 is connected to the drive plate 25 to improve the stability of the upright 50 and prevent the connecting rod 70 from bending.

[0051] Specifically, see Figure 5 The outer edge of the tray 10 is provided with a first annular groove 15, and the rotating ring 20 is provided with a second annular groove 22 on the side facing the tray 10. At least three support wheels 21 are rotatably mounted in the second annular groove 22 or the first annular groove 15 via at least three pins 23, and the support wheels 21 extend into the first annular groove 15 or the second annular groove 22. With the above structure, the rotating ring 20 can rotate around the tray 10.

[0052] In this embodiment, the pin 23 is a flat-headed cylindrical pin with a hole, and a cotter pin 24 is installed at the lower end of the pin 23 to limit the pin 23. The larger end of the pin 23 is installed by means of a countersunk hole to prevent the protruding side of the pin 23 from obstructing the unbundling of the paper 81.

[0053] In this embodiment, see Figure 5 A support ring 16 is fixed to the lower side of the tray 10. The cross-section of the support ring 16 is "L" shaped, and a first annular groove 15 is formed between the outer side of the support ring 16 and the lower side of the tray 10.

[0054] Furthermore, if the installation position of the geared motor 60 is inaccurate, or if the output shaft of the geared motor 60 is not in the center position, the output shaft of the geared motor 60 will be in an eccentric state, and the connecting rod 70 will be stuck when it rotates.

[0055] Therefore, as Figure 5 As shown, the drive plate 25 has a sliding hole 26 through which the connecting rod 70 passes. Grease is applied for lubrication between the connecting rod 70 and the sliding hole 26. When the output shaft of the geared motor 60 is in an eccentric state, the connecting rod 70 will not jam when rotating.

[0056] Example 4:

[0057] Based on embodiment 1, 2, or 3, in this embodiment, see Figure 3 , 6 There are two uprights 50, with a gap 51 between them. The two uprights 50 are provided to improve the stability of unbundling. When the diameter of the yarn tube paper 80 becomes smaller, the paper 81 can be pushed out through the inner upright 50.

[0058] During installation, the upright 50 is welded to the connecting rod 70 or the swivel 20. The paper 81 of the yarn tube 80 passes through the gap 51.

[0059] The working principle or operation process of this utility model is as follows:

[0060] See Figure 6 , 7In use, the lifting pipe 30 of the paper feeding device is horizontally passed over the center paper tube of the yarn tube 80. Then, the hook of the lifting equipment is hooked onto the lifting lug 40, and the lifting equipment is used to lift the yarn tube 80 into the position shown. Figure 7 The state shown.

[0061] After manually untying a section of paper 81 from the yarn tube 80, the paper 81 is passed through the gap 51 between the two uprights 50, and then the yarn tube 80 is lifted above the pulping equipment. Due to the gravity of the paper 81, there is a tendency for the paper 81 to unbundle from the yarn tube 80, but the paper 81 is blocked by the uprights 50, and the paper 81 will not automatically unbundle during the lifting process.

[0062] When the geared motor 60 starts, the upright 50 begins to rotate around the tray 10 and the yarn tube paper 80. The rotation direction of the upright 50 is the same as the unbundling direction of the paper 81, thereby controlling the unbundling speed of the paper 81. When it is necessary for the paper 81 to stop unbundling, the geared motor 60 is turned off, and the upright 50 blocks the paper 81, so that the paper 81 will not unbundle automatically.

[0063] This enables automatic unbundling and feeding of rolled yarn tubes 80, thereby reducing the labor intensity of workers.

[0064] It should be noted that since the number of yarn tubes 80 that need to be re-rolled is small, and the unbundling and feeding are intermittent during the re-rolling process, and the running time of each machine is short, the heat dissipation requirements of the geared motor 60 do not need to be considered in this application.
