Description

Technical Field

[0001] This utility model relates to the technical field of spool turning machine structure, specifically to a spool clamping device and its spool turning machine. Background Technology

[0002] A rewinding machine (also known as a winding machine or yarn rewinding machine) is a type of textile machinery used to rewind yarns and silk threads from smaller packages (such as bobbins or bobbins) into larger bobbins for subsequent weaving, dyeing, or packaging.

[0003] To prevent the spools on the rewinding machine from jumping or falling during high-speed rotation, a clamping device is installed on the rewinding machine to clamp and limit the spools. For example, CN222570480U discloses a spool clamping device for a rewinding machine, including a support base. Positioning components are symmetrically fixedly installed on the top of the support base. A spool is slidably sleeved on the top of the positioning component. The positioning component includes a first positioning device and a second positioning device. The first positioning device is fixedly installed on the top side of the second positioning device. The first positioning device includes a positioning handle, a clamping plate, a threaded rod, and a threaded cylinder. The clamping plate is rotatably installed on the outer ring of the positioning handle. The positioning handle is fixedly installed at the center of the top of the threaded rod, and the threaded rod is threadedly inserted into the center of the top of the threaded cylinder.

[0004] In the process of splitting the spool, the above-mentioned spool clamping device requires manual operation of the clamping plate in the first positioning device and the guide handle in the second positioning device to release the clamping limit on the spool before it can be moved out, which is relatively troublesome. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bobbin clamping device and its rewinding machine, so as to solve the problem that the operation of the existing clamping device is relatively troublesome when releasing the bobbin from the clamping limit.

[0006] To achieve the above objectives, the first aspect of this utility model adopts the following technical solution: a spool clamping device for connecting to the bearing of a rewinding machine, comprising:

[0007] A base, which is connected to the bearing of the rewinding machine and is used to limit the contact of one end of the rewind drum;

[0008] A bottom clamping structure is provided on the base and is used to embed one end of the spool and elastically abut against it. The bottom clamping structure is also provided with a bottom clamping release control part.

[0009] A top pressing structure is connected to a bottom clamping structure and is used to press and fix the other end of the bobbin. The top pressing structure is equipped with a top pressing release control part.

[0010] The adjustment unit is connected to both the bottom clamping release control unit and the top pressing release control unit, and is used to trigger the unlocking of both the bottom clamping structure and the top pressing structure.

[0011] The second aspect of this utility model adopts the following technical solution: a spool turning machine, including a spool clamping device according to the first aspect of this utility model.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this spool rewinding machine, the spool clamping device clamps the spool by placing the base against one end of the spool and tightening the bottom clamping structure inside that end of the spool. Then, the top pressing structure presses and fixes the other end of the spool, thus stably limiting and fixing the spool. When it is necessary to remove the spool, the bottom clamping release control unit and the top pressing release control unit are triggered by the adjustment unit, which unlocks the spool from both the bottom clamping structure and the top pressing structure. Then the spool can be removed. The operation of removing the spool is relatively more convenient and faster. Attached Figure Description

[0018] The present invention will be further described in detail below through specific embodiments:

[0019] like Figure 1 , Figure 2 as well as Figure 3 As shown in the figure, this utility model embodiment proposes a spool clamping device for connecting to the bearing of a spool turning machine. It includes a base 2, a bottom clamping structure 3, a top pressing structure 4, and an adjusting part. The base 2 is connected to the bearing of the spool turning machine and is used to limit and stop one end of the spool 1. The bottom clamping structure 3 is disposed on the base 2 and is used to elastically abut one end of the spool 1. The bottom clamping structure 3 is equipped with a bottom clamping release control part 5. The top pressing structure 4 is connected to the bottom clamping structure 3 and is used to press and fix the other end of the spool 1. The top pressing structure 4 is equipped with a top pressing release control part. The adjusting part is connected to both the bottom clamping release control part 5 and the top pressing release control part, and is used to trigger the unlocking of both the bottom clamping structure 3 and the top pressing structure 4.

[0020] The bobbin clamping device in this solution is used as follows:

[0021] Install the connecting column at the bottom of the base 2 onto the bearing of the rewinding machine for rotational connection. Then adjust the bottom clamping structure 3 and the top pressing structure 4 to be in the retracted state. At this time, pass the spool 1 through the bottom clamping structure 3 and the top pressing structure 4 until it abuts against the base 2. Then adjust the bottom clamping structure 3 and the top pressing structure 4 to the locked state. At this time, the bottom clamping structure 3 is placed inside the spool 1 and elastically abuts against it. The top pressing structure 4 presses and fixes the other end of the spool 1 to complete the installation of the spool 1 and ensure that the spool 1 remains stable during operation.

[0022] When spool 1 needs to be split:

[0023] The bottom clamp release control unit 5 and the top pressing release control unit are triggered by the adjustment unit. The bottom clamp release control unit 5 and the top pressing release control unit respectively drive the bottom clamping structure 3 and the top pressing structure 4 to disengage from the limit fixation of the wire drum 1 to unlock it. Then, the wire drum 1 can be held and moved away from the base 2 to complete the disassembly of the wire drum 1, making the disassembly of the wire drum 1 more convenient and faster.

[0024] To better understand this solution, the bottom clamping structure 3 and the top pressing structure 4 will be optimized below.

[0025] First is the bottom clamping structure 3.

[0026] like Figure 2 and Figure 3As shown, according to another embodiment of the present invention, the spool clamping device includes a bottom clamping structure 3 comprising a tensioning block 31 and a first elastic support member 32. There are two tensioning blocks 31 arranged facing each other on the top of the base 2, and both tensioning blocks 31 are slidably connected to the base 2. The bottom clamping release control part 5 is distributed between the two tensioning blocks 31 and is used to drive the two tensioning blocks 31 to move towards each other. There are multiple first elastic support members 32 connected between the two tensioning blocks 31.

[0027] In this solution, when the bottom clamping structure 3 needs to be tightened in the spool 1 for limiting and fixing, the two tensioning blocks 31 are adjusted to move towards each other a certain distance, and the first elastic support 32 is in a compressed state. At this time, the two tensioning blocks 31 are restricted to this state so that the two tensioning blocks 31 can be smoothly inserted into the spool 1. Then the restriction on the two tensioning blocks 31 is released, the first elastic support 32 unfolds, and drives the two tensioning blocks 31 to move away from each other to abut against the inner wall of the spool 1 for limiting and fixing.

[0028] To make the above process easier to operate, the two tensioning blocks 31 are arranged symmetrically, and each tensioning block 31 includes a semi-conical segment 311 and a semi-cylindrical segment 312 connected to the large end of the semi-conical segment 311. The elastic support and the bottom clamping release control part 5 are connected to the semi-conical segment 311 or the semi-cylindrical segment 312.

[0029] In this embodiment, the elastic support can be a spring or an elastic telescopic rod. Multiple elastic supports are distributed between the two semi-conical sections 311 and the two semi-cylindrical sections 312 to make the opposing or separating movements of the two tensioning blocks 31 more stable. The multiple elastic supports cooperate to provide force for the two tensioning blocks 31 to tighten and abut against the inside of the spool 1. Furthermore, they connect the two tensioning blocks 31 together when they are not under force, so that the semi-conical sections 311 of the two tensioning blocks 31 cooperate to support the two tensioning blocks. The tensioning block 31 acts as a guide during the process of being inserted into the spool 1. No additional force is needed to drive the two tensioning blocks 31 to move towards each other. The spool 1 is simply moved so that the semi-conical sections 311 of the two tensioning blocks 31 are inserted into the spool 1. The semi-conical sections 311 of the two tensioning blocks 31 are squeezed by the spool 1 to make the two tensioning blocks 31 move towards each other until one end of the spool 1 abuts against the base 2. At this time, the semi-cylindrical sections 312 of the two tensioning blocks 31 abut against the inside of the spool 1 to tighten and fix them. The operation is more convenient and faster.

[0030] Secondly, there is the bottom clamp release control unit 5.

[0031] like Figure 2 and Figure 3As shown, according to another embodiment of the present invention, the spool clamping device includes a bottom clamping release control unit 5 comprising a bottom electromagnet 51 and a bottom adsorption iron block 52. The bottom electromagnet 51 is embedded in one of the tensioning blocks 31 and is connected to the adjustment unit; the bottom adsorption iron block 52 is embedded in another tensioning block 31 and is arranged facing the bottom electromagnet 51.

[0032] In this embodiment, the bottom electromagnet 51 and the bottom adsorption iron block 52 are distributed between the semi-conical segment 311 and the semi-cylindrical segment 312 of the corresponding tensioning block 31. When the bottom clamping structure 3 needs to be unlocked, the bottom electromagnet 51 is energized by the adjustment part, and a magnetic force is generated on the bottom electromagnet 51 to attract the bottom adsorption iron block 52, driving one of the tensioning blocks 31 to move towards the other tensioning block 31. The first elastic support member 32 contracts, and the two tensioning blocks 31 are released from the tensioning fixation of the wire spool 1. Then the wire spool 1 can be moved to disengage from the two tensioning blocks 31.

[0033] In this embodiment, the bottom electromagnet 51 and the bottom adsorption block 52 are distributed on one side of the two tensioning blocks 31 facing each other, and at least the bottom adsorption block 52 extends beyond the corresponding tensioning block 31. In this embodiment, both the bottom electromagnet 51 and the bottom adsorption block 52 partially extend beyond the tensioning block 31. When the bottom electromagnet 51 is energized, it attracts the bottom adsorption block 52 until they adhere together. The portions of the bottom electromagnet 51 and the bottom adsorption block 52 extending beyond the corresponding tensioning block 31 then contact each other, serving a limiting function to prevent excessive pressure on the first elastic support member 32.

[0034] It should be noted that when the bottom electromagnet 51 is energized, the attraction force it generates on the bottom adsorbed iron block 52 is greater than the elastic force of the multiple first elastic support members 32, causing the tensioning block 31 to move and disengage from the spool 1. This process has been verified through prior experiments and is working normally.

[0035] Next is the top pressing structure 4.

[0036] like Figure 1 , Figure 2 as well as Figure 3As shown, according to another embodiment of the present invention, the spool clamping device includes a top pressing structure 4 comprising a mounting block 41, a sliding block 42, and a pressing block 43. The mounting block 41 is connected to the bottom clamping structure 3 via a guide rod 44. The sliding block 42 is slidably connected to the guide rod 44 and arranged facing the mounting block 41. An electric telescopic device 45 is connected between the sliding block 42 and the mounting block 41. One end of the sliding block 42 has a connecting groove arranged perpendicularly to the guide rod 44. One end of the pressing block 43 is slidably connected in the connecting groove and connected to the inner wall of the connecting groove via a second elastic support member. The other end is used to press and fix the end of the spool 1. A top pressing release control unit is provided between the pressing block 43 and the inner wall of the connecting groove and is used to release the pressing block 43 by sliding it into the connecting groove.

[0037] When the top pressing structure 4 is used in conjunction with the bobbin 1, the following is true:

[0038] Press the pressing block 43 to house it in the connecting groove. The second elastic support retracts. Then move the spool 1 to insert the top pressing structure 4 into the spool 1 until the spool 1 abuts against the base 2. At this time, the mounting block 41 and the sliding block 42 are both inserted to the outside of the end of the spool 1 away from the base 2. Under the action of the second elastic support, one end of the pressing block 43 moves out from the connecting groove to the outside of the edge of one end of the spool 1. Activate the electric telescopic device 45 to move the sliding block 42 towards the spool 1 until the pressing block 43 abuts against the spool 1 to press and fix the spool 1.

[0039] When it is necessary to release the pressure of the top pressing structure 4 on the bobbin 1:

[0040] The top pressing release control unit is triggered by the adjustment unit. The top pressing release control unit drives the pressing block 43 to slide into the connecting groove. The pressing block 43 is released from the pressing and fixing of the wire cylinder 1, and the top pressing structure 4 completes the unlocking of the wire cylinder 1.

[0041] The pressing block 43 has a guide slope on its end face away from the base 2. This facilitates the sliding contact between the end of the spool 1 and the guide slope when the top pressing structure 4 is inserted into the spool 1, thereby driving the pressing block 43 to move into the connecting groove and making the assembly of the spool 1 faster.

[0042] In this embodiment, one end of the guide rod 44 is specifically fixedly connected to the semi-conical segment 311 in one of the tensioning blocks 31; the second elastic support can be a spring or an elastic telescopic rod, and the electric telescopic device 45 can be an electric telescopic rod.

[0043] Next is the top pressure release control unit (the structure of the top pressure release control unit can refer to the structure of the bottom pressure release control unit, which is not shown in the attached figure).

[0044] According to another embodiment of the present invention, the spool clamping device includes a top pressing release control unit comprising a top electromagnet and a top adsorption iron block. The top electromagnet is disposed on the inner wall of the connecting groove and is connected to the adjustment unit. The top adsorption iron block is disposed on the pressing block 43 and is arranged facing the top electromagnet.

[0045] When it is necessary to release the pressure of the top pressing structure 4 on the bobbin 1:

[0046] The top electromagnet is energized by the adjustment unit, and the top electromagnet generates magnetic force, which drives the top adsorbed iron block to move towards it, thereby driving the pressing block 43 to move into the connecting groove until the top adsorbed iron block and the top electromagnet stick together, at which point the pressing block 43 is released from pressing the wire cylinder 1.

[0047] The pressing surface of the pressing block 43 can be provided with an elastic buffer coating to prevent damage to the spool 1 when the pressing block 43 presses it. A sensor can also be installed within the elastic buffer coating. When the pressing block 43 presses the spool 1, if the sensor detects that the force applied by the pressing block 43 to the spool 1 is a preset force, this signal is fed back to the controller. The controller then sends a stop signal to the electric telescopic rod. Once the electric telescopic rod stops operating, the force applied by the pressing block 43 to the spool 1 is the preset force. Under this preset force, the spool 1 can be pressed and fixed without causing damage. This preset force can be adjusted appropriately according to different situations, which will not be elaborated here.

[0048] It should be noted that when the top electromagnet is energized, the attraction force it generates on the top-adsorbed iron block is greater than the elastic force of the second elastic support, and it can also overcome the applied force, allowing the pressing block 43 to move into the connecting groove to release the pressure. This process was verified through prior experiments and can function normally.

[0049] Finally, there is the adjustment department.

[0050] According to another embodiment of the present invention, the spool clamping device includes an adjustment unit comprising a relay module connected to both the top electromagnet and the bottom electromagnet 51, and a controller connected to the relay module; the energization or de-energization of the top electromagnet and the bottom electromagnet 51 is controlled by the relay module through operation on the controller (e.g., a computer).

[0051] When this spool clamping device clamps spool 1:

[0052] Hold one end of the spool 1 to abut the guide slope of the pressing block 43 and assist in driving the pressing block 43 to move into the connecting groove. The mounting block 41 and the sliding block 42 are both inserted into the spool 1.

[0053] Continue moving the spool 1. One end of the spool 1 slides against the semi-conical sections 311 of the two tensioning blocks 31, driving the two tensioning blocks 31 to move towards each other until the two tensioning blocks 31 penetrate into the spool 1. One end of the spool 1 abuts against the base 2 and is tightened and fixed by the two tensioning blocks 31. The mounting block 41 and the sliding block 42 are both inserted to the other end of the spool 1, and one end of the pressing block 43 also slides from the connecting groove.

[0054] The electric expansion joint 45 is activated by the controller, which drives the pressing block 43 to move closer to the spool 1 until the sensor sends a signal to the controller to stop the electric expansion joint 45; at this time, the spool 1 is assembled.

[0055] When spool 1 needs to be split:

[0056] By operating the controller, both the top electromagnet and the bottom electromagnet 51 are energized, the two tensioning blocks 31 move towards each other, the pressing block 43 moves into the connecting groove, and the spool 1 is unlocked.

[0057] Then, hold the spool 1 and move it away from the base 2 to complete the disassembly of the spool 1.

[0058] The above-mentioned spool clamping device is applied to a spool rewinding machine. According to another embodiment of the present invention, the spool rewinding machine includes a spool clamping device as described in any of the above embodiments to stably install the spool 1, and the spool 1 is convenient and quick to disassemble.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
