Description

Technical Field

[0001] The present invention relates to the field of winding and packaging of wire materials (such as hoses and cables) and coiled materials (such as paper tapes), and in particular to a new winding wheel for hoses and soft wires and a winding machine with the new winding wheel. Background Art

[0002] After the hose, cord and other wires are manufactured, they need to be rolled into rolls and bundled before they can be transported and sold. There are two ways to bundle them. One is to tie them with a cable tie (such as Figure 1 ), one is the film tape through the core wrap (such as Figure 2 ). The winding of the wire is usually completed by a winder, and the winding wheel is the component of the winder that rolls the wire into a coil.

[0003] The winding wheel comprises a winding core, a first baffle and a second baffle, the first baffle and the second baffle are respectively connected to two ends of the winding core, the first baffle and the second baffle are respectively substantially perpendicular to the winding core, the first baffle or the second baffle can be disassembled, the first baffle, the second baffle and the winding core have aligned notches to form a winding groove running through the axial direction of the winding core, and there are usually four winding grooves.

[0004] The winding machine usually includes a frame, a power source, a speed reduction mechanism, a winding wheel, a wire arrangement device, etc. The frame is where the power source, winding wheel, wire arrangement device, etc. are installed. The power source is a mechanical device that can generate power, including electric motors, engines, pneumatic motors, etc., but electric motors are usually used. The motor usually also needs to transmit the rotation to the winding wheel through a speed reduction mechanism so that the winding wheel can rotate around its core axis. The wire arrangement device can make the wire swing back and forth evenly between the two baffles of the winding wheel, so that the wire can be evenly wound on the winding wheel layer by layer. When the winding machine winds the wire, the head end of the wire passes through the wire arrangement mechanism and is fixed on the winding wheel. When the switch is pressed to power on, the winding wheel rotates and the wire is wound on the winding wheel. When the wire is rolled to the appropriate size, the winder is powered off and stopped. At this time, the worker uses the winding groove of the winding wheel to tie the wire roll with a cable tie through the heart. It can be tied manually or with a cable tie machine, such as Figure 1 As shown, a cable tie 404 is used to pass through the inner space of the wire coil and bind the ring body of the wire coil. If there are four winding grooves, at most four cable ties can be used.

[0005] After the manual or mechanical threading and winding is completed, cut off the tail end of the wire, remove the detachable retaining frame of the winding wheel, and then remove the wire coil from the winding wheel of the winding machine. Wires of different materials have different bundling requirements. Some wires also need to be further wrapped with film tape on the basis of the cable tie threading. Figure 2 The wire coil is transferred to the next station, and the worker holds a roll of film tape 405, releases the film tape while rotating the wire coil, passes it through the core and wraps it around the cable tie, unties it in turn and removes the cable tie, and finally completes the closed protection of the wire coil ring body by the film tape.

[0006] From the above, it can be seen that the winding wheel of the existing winding machine has the following disadvantages. First, when the wire roll is tied with the cable tie through the center of the winding wheel, the number and position of the cable tie are limited by the setting of the winding groove on the winding wheel. Second, the film tape through the center of the wire roll cannot be completed on the winding wheel. The cable tie needs to be solidified first, then removed and transferred to a special workbench for film tape through the center of the winding. Summary of the invention

[0007] The technical problem to be solved by the present invention is to improve the defects of the above-mentioned prior art to provide a new winding wheel on which the wire roll can be wrapped with film tape and tied with cable ties at any position and quantity, and a winding machine having the new winding wheel.

[0008] In order to solve the above technical problems, the present invention provides a new type of winding wheel, which includes a winding core, a first baffle frame, and a second baffle frame. The first baffle frame and the second baffle frame are respectively connected to or matched with the two ends of the winding core, and the first baffle frame and the second baffle frame are respectively basically perpendicular to the winding core (the axis of the winding core is basically perpendicular to the restraining baffle surfaces of the two baffle frames for the wire coil), the first baffle frame or the second baffle frame can be disassembled, and the first baffle frame, the second baffle frame and the winding core have aligned notches to form a winding groove, which is characterized in that: the winding core is provided with a rotation structure.

[0009] The winding core is the axial core around which the wire is wound to form a coil, which constrains the coil. Figure 1 Figure 2 The hollow curved surface 401. The outer shape of the winding core is usually approximately cylindrical (of course, it can also be other shapes, such as a polygonal column). Approximately cylindrical means: 1. The outer shape of the winding core can have gaps, for example, the existence of the winding groove makes the outer shape of the winding core have gaps, and for example, the winding core is formed by rollers distributed along the cylindrical surface with gaps, etc. 2. The outer shape of the winding core can be slightly thicker at one end and slightly thinner at the other end, so that it is convenient to take out the wire coil from the thin end.

[0010] The retaining frame is a frame that constrains the wire material so that it can be wound on the winding core. The retaining frame can be a frame with gaps or a basically complete surface. The wire coil is formed under the constraint of the retaining frame. Figure 1 Figure 2The two side planes 403 (each coil has two side planes, and only one is marked in each figure), regardless of the form of construction, are all referred to as baffles that can play the above-mentioned restraining role. The first baffle and the second baffle are respectively connected or matched with the two ends of the winding core. The connection between the baffle (the first baffle or the second baffle) and the end of the winding core can be connected through a connecting piece or can be made into an integral connection. The cooperation between the baffle (the first baffle or the second baffle) and the two ends of the winding core is that the baffle contacts or approaches the end of the winding core and constrains the wire on the winding core when winding. Usually, to complete this cooperation, the baffle can rotate basically synchronously with the winding core. There are two ways to achieve synchronous rotation. The first is that the baffle and the winding core that are in contact with each other rotate one to drive the other to rotate (for example, there is a sufficiently large friction between them), and the second is that the winding core and the baffle contact or approach each other but rotate synchronously (the winding core and the cooperating baffle each actively rotate). In practical applications, the matching baffle is usually connected to the end of a shaft on the winding machine and can rotate around its axis. The shaft is on the same axis as the winding core. The matching baffle and the winding core can be relatively close or far away through the mechanical structure on the winding machine. When the winding machine is winding, it is close to and completes the constraint on the wire. When the winding is completed and the wire needs to be removed, it is far away. We also call this action of moving away the baffle disassembly. The baffle is disassembled in order to remove the wire coil from the winding core. It can be that the baffle is truly separated or deformed. In short, as long as the constraint is released so that the wire coil can be removed from the winding core, it is what we call the baffle disassembly.

[0011] The retaining frame and the winding core are both provided with notches. Regardless of the shape, size, and depth of the notches of the retaining frame and the winding core, as long as they can cooperate to form a winding groove that runs through the winding core axially, and through which a cable tie or film tape can be inserted to achieve cable tie through-core bundling or film tape through-core wrapping, it is the notch we are talking about. The novel winding wheel is usually provided with only one winding groove.

[0012] The beneficial rotation structure is a structure that facilitates the rotation of the wire coil relative to the winding wheel with the winding core as the axis. When the wire coil rotates relative to the winding wheel, it will be subject to resistance from the winding wheel. The beneficial rotation structure achieves the beneficial rotation function by reducing this resistance. The beneficial rotation structure includes a coating beneficial rotation structure and a rolling body beneficial rotation structure. The coating beneficial rotation structure reduces the sliding friction between the winding wheel and the wire coil. Specifically, a coating with a very small sliding friction coefficient is coated at the contact point between the winding wheel and the wire coil, such as a layer of polytetrafluoroethylene. The rolling body beneficial rotation structure converts the original sliding friction between the winding wheel and the wire coil into a relatively small rolling friction. Specifically, a rolling body is provided at the contact point between the winding wheel and the wire coil. The relative rotation resistance is reduced by the rolling of the rolling body. The rolling body is a rotating body or a nearly rotating body, which can be a cylinder, a truncated cone, a sphere, a polygonal prism, etc. By providing the beneficial rotation structure on the winding core, the resistance brought by the winding core when the wire coil rotates relative to the winding wheel is reduced.

[0013] As mentioned above, a winding machine usually includes a frame, a power source, a speed reduction mechanism, a winding wheel, a wire arrangement device, etc. However, according to needs and conditions, we can make the winding machine simpler or more complex. For example, the wire arrangement device can be omitted and manual wire arrangement can be adopted. For example, frequency conversion speed regulation can be used instead of the speed reduction mechanism. The winding machine can be complex or simple. However, as long as the winding machine has the new winding wheel, it is the winding machine of the present invention.

[0014] The new winding machine of the present invention is the same as the prior art when winding the wire, but it is different when bundling. After winding, the power source stops outputting power to stop the winding wheel from rotating. At this time, the wire roll is still constrained on the winding wheel, the head end of the wire is loosened and regulated, and the tension of the tail end of the wire is maintained, so that all the restraining forces still exist when winding the wire, and the wire roll will not be deformed and loose. The worker turns the wire roll by hand, and the winding core rotation structure reduces the resistance brought by the winding core when the wire roll rotates relative to the winding wheel, so that the wound wire roll can rotate relative to the winding wheel with the winding core as the axis, that is, the winding wheel The wire roll is stationary while rotating. The worker first wraps a small section of the wire roll with the film tape through the winding groove. After completing a small section, the wire roll is rotated and wrapped with another small section. In this way, the entire wire roll can be wrapped continuously, so that the film tape wrapping of the wire roll can be realized on the winding wheel; or the worker turns the wire roll to the required position by hand and stops, and ties it through the winding groove. The wire roll can be rotated and stopped for tying multiple times, and any position and number of ties can be tied through the winding groove. After bundling, the tail end of the wire is cut off, and the bundled wire roll can be taken out by disassembling the retaining frame. In this way, the present invention provides a new winding wheel on which the wire roll can be wrapped with the film tape, thereby eliminating the intermediate link of the solidification of the tie in the prior art, and a winding machine having the new winding wheel, and also provides a new winding wheel that can tie any position and number of ties through the heart and a winding machine having the new winding wheel.

[0015] Further optimization, in order to further reduce the resistance of the wire coil when it rotates relative to the winding wheel and make the rotation of the wire coil smoother, a rotation structure is also provided on the baffle frame on the basis of the rotation structure provided on the winding core. The rotation structure on the first baffle frame or the second baffle frame will reduce the resistance brought by the baffle frame when the wire coil rotates relative to the two baffle frames. The rotation structure on the baffle frame is also a coating rotation structure or a rolling body rotation structure.

[0016] For further optimization, a gap filling structure can be provided at the gap of the winding core or the baffle frame of the winding wheel. When the wire roll is wound, the gap filling structure will fill the gap of the winding core and the baffle frame, making the wire roll neater during winding. When the wire roll is bundled, the gap filling structure can be removed to expose the winding groove.

[0017] For further optimization, the winding core of the winding wheel is set to be a retractable winding core that can be retracted and expanded and restored. The retractable winding core usually includes at least two parts that are spliced ​​along the axial direction of the winding core, at least one part of which can be retracted inwardly, and the retraction makes the winding core smaller. Usually, we retract the winding core after the wire is wound. After shrinking, it is convenient to take the wire roll out from the winding core.

[0018] For further optimization and to reduce labor intensity, we configure a power source on the rolling body of the rolling body rotation structure set on the winding core or the baffle of the winding wheel. Configuring the power source means setting an electric motor, an engine, a pneumatic motor, etc. on the winding wheel. Usually the power source is an electric motor, and the power source and the rolling body are matched in transmission. The transmission match is the match of transmitting rotational motion, that is, the power source directly or through a transmission member transmits the rotation to the rolling body. Through the transmission match, the power source drives the rolling body to rotate around its own axis. The rolling body on the winding wheel can be partially or fully matched with a power source as needed. After adjusting the rotation speed and direction of each rolling body, it can provide power for the rotation of the wire roll during bundling. In order to prevent the rolling body from slipping when driving the wire roll, the surface of the rolling body can be knurled, toothed, and roughened.

[0019] In addition to manually rotating the wire coil, there are three sources of power for rotating the wire coil during baling: the first is the power source from the rolling body configuration, the second is the wire coil driving device configured by the winding machine, and the third is the power from the rolling body power source and the wire coil driving device simultaneously. The wire coil driving device is usually driven by an electric motor, which rotates the driving wheel, and the driving wheel directly contacts and rubs the outer curved surface 402 of the wire coil to rotate the wire coil, or the driving wheel contacts and rubs the outer curved surface 402 of the wire coil through the crawler to rotate the wire coil. Usually, the device is far away from the wire coil, and only when baling is needed, the device approaches and contacts the wire coil.

[0020] After the above three methods solve the power source for the rotation of the wire coil during bundling, the winding machine can be equipped with a cable tie machine or a wrapping machine to realize the mechanization and automation of "winding - cable tie through the core for bundling" or "winding - film tape through the core for wrapping". The wrapping machine described here is separated from the existing coating machine that wraps the wire coil with a film tape through the core. The wire is not easy to loosen and deform after being rolled into a coil, so the wire coil can be taken off the winding wheel and placed on the coating machine for wrapping. The existing coating machine is divided into two major parts, the clamping part and the wrapping part. The clamping part clamps the wire coil and rotates slowly, and the wrapping part wraps the wire coil. We separate the wrapping part of the coating machine to make a wrapping machine. The cable tie machine or the wrapping machine is installed on a moving mechanism. The cable tie machine or the wrapping machine can be driven by a motor or a cylinder to move close to or away from the new winding wheel. With the help of logic control, mechanization and automation are realized.

[0021] The basic process of automated "reeling - cable tie threading and bundling" is: 1. Start the cable arrangement device and the winding power source at the same time to rotate the winding wheel to realize winding; 2. Stop the winding wheel after winding is completed, and align the winding groove with the cable tie machine; 3. Start the moving mechanism to move the cable tie machine to the winding wheel, and the cable tie machine moves to the inner space of the wire coil through the winding groove and stops moving after reaching its working position; 4. Start the cable tie machine to complete the cable tie threading and bundling. After completing one cable tie threading and bundling, start the power source of the rolling body rotation structure (or start the configured wire coil drive device, or start the power source of the rolling body rotation structure and the wire coil drive device at the same time) to let the wire coil rotate with the winding core of the winding wheel as the axis (the direction of rotation of the wire coil is consistent with the direction of rotation during winding), and stop at the required place to thread the cable tie again; 5. When all the required positions have completed all the cable ties, start the moving mechanism to make the cable tie machine withdraw from the inner space of the wire coil, cut off the tail end of the wire and complete the bundling.

[0022] The basic process of automated "reeling - film tape through-core wrapping" is: 1. Simultaneously start the wire arrangement device and the winding power source to rotate the winding wheel to realize winding; 2. After winding is completed, stop the winding wheel and align the winding groove with the wrapping machine; 3. Start the moving mechanism to move the wrapping machine to the winding wheel, and the wrapping machine moves to the inner space of the wire roll through the winding groove to reach its working position and then stops moving; 4. Start the wrapping machine to through-core wrap the film and start the power source of the rolling body rotation structure (or start the configured wire roll drive device, or start the power source of the rolling body rotation structure and the wire roll drive device at the same time) to let the wire roll rotate with the winding core of the winding wheel as the axis (the direction of rotation of the wire roll is consistent with the direction of rotation during winding), and thus rotate the wire roll while through-core wrapping the film. After the wire roll rotates a full circle, the entire ring body is wrapped and closed by the film tape, and then stop the rotation of the wire roll and the wrapping machine, 5. Start the moving mechanism to make the wrapping machine exit the inner space of the wire roll through the winding groove, cut off the tail end of the wire roll and complete the bundling.

[0023] In the prior art, the film tape threading and wrapping of the wire coil of the hose and soft wire cannot be mechanized and automated, and must be completed manually by a large number of workers. This is a long-standing unresolved technical problem. Now, the winding machine with the new winding wheel and the special wrapping machine have solved this problem. The factory producing hose and soft wire can greatly reduce the number of workers and improve efficiency by using the winding machine with the new winding wheel.

[0024] The present invention is also applicable to coils of certain coiled materials (such as paper coils, plastic coils) and certain wire coils that are not easy to loosen. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] Example 1.

[0042] An embodiment of the present invention, as Figure 3A novel winding wheel shown includes a winding core 3, a first stop frame 1, and a second stop frame 2. The winding core 3 is approximately cylindrical in shape with one end thicker than the other end. The thicker end of the winding core 3 is fixedly connected to the first stop frame 1, and three screws 301 are fixed to the thinner end of the winding core 3. The second stop frame 2 is provided with three stop frame through holes 201 corresponding to the screws 301. The screws 301 pass through the corresponding stop frame through holes 201 and cooperate with three butterfly nuts 202 to lock the second stop frame 2 and the winding core 3. After locking, the second stop frame 2 is substantially perpendicular to the winding core 3, that is, the winding core 3 and the second stop frame 2 are connected together through the connecting member (screw 301 and butterfly nut 202), and the first stop frame notch 110, the second stop frame notch 210, and the winding core notch 310 are aligned with each other to form a winding groove. The winding core 3 is provided with a polytetrafluoroethylene coating 320, which is the coating transfer structure described in the present invention.

[0043] Four countersunk holes 124 are provided on the first stop frame 1, and the novel winding wheel can be fixed on the transmission frame (not shown) of the winding machine by countersunk bolts. As the transmission frame driven by the motor rotates, the novel winding wheel also rotates.

[0044] When winding, the head end of the wire is fixed on the new winding wheel, specifically, it can be pressed against one end of the winding core 3 and close to the inner wall of the winding core notch 310, then the motor is started to drive the winding wheel to rotate, and the wire is swung at the same time, so that the wire is evenly wound on the winding core 3 layer by layer and constrained by the first stop frame 1 and the second stop frame 2 to form a wire coil. After winding, the motor is stopped, the winding wheel stops, the tail end of the wire is cut off, and the tail end is fixed to the wire coil, the head end of the wire fixed on the winding core 3 is released, and then the winding wheel is kept stationary, and the wire coil is rotated in the reverse winding direction with the winding core as the fixed axis (the wire coil is rotated in the reverse winding direction, which can be To ensure that the wire coil is not loose without constraining the head end of the wire), the wire coil can be rotated because of the existence of the core coating rotation structure polytetrafluoroethylene coating 320. The wire coil is rotated to the required place and the cable tie is passed through the winding groove to complete the through-core bundling of the wire coil, or the worker first uses a film tape to pass through the winding groove to through-core and wrap a small section. After completing a small section, the wire coil is rotated and wrapped again. In this way, the entire wire coil can be through-core and wrapped continuously. After bundling is completed, the butterfly nut 202 is loosened, the second retaining frame 2 is disassembled and the bundled wire coil is taken out. Because the end of the winding core close to the second retaining frame 2 is slightly smaller than the other end, it is relatively easy to take out the wire coil.

[0045] It can be further optimized by coating polytetrafluoroethylene at the parts where the first retaining frame 1 and the second retaining frame 2 contact with the wire coil to form a coating rotation structure, which makes it more convenient to rotate the wire coil when bundling.

[0046] Example 2.

[0047] This embodiment is a new type of winding wheel. Figure 4 As shown, it includes a winding core 3, a first baffle 1, and a second baffle 2. The first baffle 1 is fixedly connected to both ends of the winding core 3, the first baffle 1 and the second baffle 2 are respectively substantially perpendicular to the winding core 3 (the axis of the winding core is substantially perpendicular to the restraining baffle surfaces of the two baffles to the wire coil), the second baffle 2 can be detached, the first baffle 1 and the second baffle 2 and the winding core 3 have aligned notches to form a winding groove, and the feature is that: the winding core 3 is provided with a rolling body rotation structure.

[0048] The winding core 3 is divided into two parts, an upper part and a lower part (the upper part and the lower part in this embodiment are distinguished by the direction shown in the figure), the upper part is made into an integral fixed connection with the second retaining frame 2, and the lower part is made into an integral fixed connection with the first retaining frame 1, and the upper and lower parts can be assembled together to form a winding core 3 that is approximately cylindrical after assembly. The upper part of the winding core 3 is fixed with three positioning pins 342 and two clamping seats 343, and the lower part of the winding core 3 has three pin holes 341 and two bases 347 that match the positioning pins 342. The rotating screw 345 is rotatably connected to the base 347 through the pin 346. After the positioning pin 342 is inserted into the corresponding pin hole 341, the rotating screw 345 is rotated to make it clamp into the clamping seat 343, and then the clamping nut 344 is screwed to clamp the base 347 and the clamping seat 343 so that the upper and lower parts of the winding core 3 are assembled and fixed. In addition, the first baffle frame notch 110, the second baffle frame notch 210 and the winding core notch 310 cooperate with each other to form a winding groove; the first baffle frame 1, the second baffle frame 2 and the winding core 3 are processed with holes at the contact points with the wire coil, and the steel balls are installed in the holes, which are conducive to the ball locking process to lock the steel balls in the holes. The steel balls protrude slightly from the surface, and the steel balls can roll flexibly and are not easy to fall off. That is, the first baffle frame 1, the second baffle frame 2 and the winding core 3 are provided with a spherical rolling body-shaped rotation structure. The smaller the diameter of the steel balls and the greater the arrangement density, the better the rotation effect.

[0049] The first stop frame 1 is provided with three transmission frame connecting screws 180, which can be used together with nuts to fix the new winding wheel on the transmission frame of the winding machine (not shown in the figure). As the transmission frame driven by the motor rotates, the new winding wheel also rotates.

[0050] When winding, the head end of the wire is fixed on the winding wheel, specifically, the head end of the wire is attached to the inner wall of one end of the winding core 3 close to the winding core notch 310, and then the motor is started to drive the winding wheel to rotate, and the wire is swung at the same time, so that the wire is evenly wound on the winding core 3 and constrained by the first stop frame 1 and the second stop frame 2 to form a wire coil. After winding, the tail end of the wire is cut off and the tail end is attached to the wire coil, the head end of the wire fixed on the winding core 3 is released, and the head end of the wire is also attached to the wire coil, and then the winding wheel is kept stationary, and the wire coil is rotated manually with the winding core 3 as the fixed axis. Due to the presence of the ball 340, the wire coil is easy to be rotated. The wire coil is rotated to the required position and the cable tie is passed through the winding groove to complete the through-core bundling of the wire coil, or the worker first uses a film tape to pass through the winding groove to through-core and wrap a small section, and then rotates the wire coil and wraps another small section after completing a small section. In this way, the entire wire coil can be through-core wrapped continuously; after bundling is completed, the clamping nut 344 is loosened, and the rotating screw 345 is rotated to remove the second retaining frame 2 together with the upper part of the winding core, thereby realizing the disassembly of the second retaining frame 2 to release the constraint on the wire coil, thereby removing the wire coil from the winding wheel.

[0051] Example 3.

[0052] An embodiment of the present invention, as Figure 5 , Figure 6 , Figure 7 A novel winding wheel is shown, comprising a winding core 3, a first baffle 1, and a second baffle 2. The first baffle 1 is fixedly connected to one end of the winding core 3, the second baffle 2 is rotatably connected to one end of the winding core 3, the first baffle 1 and the second baffle 2 are respectively substantially perpendicular to the winding core 3 (the axis of the winding core is substantially perpendicular to the restraining baffle surfaces of the two baffles for the wire coil), the second baffle 2 can be deformed, the first baffle 1 and the second baffle 2 and the winding core 3 have aligned notches to form a winding groove, and the characteristic is that: the winding core 3 is provided with a rolling body rotation structure.

[0053] The winding core 3 is composed of 10 round rods of the same shape (the round rods are blocked by the winding core cylinder 330 and are not shown in the figure) and 10 winding core cylinders 330. The two ends of the 10 round rods are respectively connected with the first block frame inner C ring 121 and the second block frame inner C ring 221 of the same diameter, and the annular surfaces of the two inner C rings are parallel and the C-shaped notches are aligned. The 10 round rods are connected in parallel with gaps along the side of the cylinder to form a winding core that is approximately cylindrical. The round rods are provided with a winding core cylinder 330 that can rotate with the round rod as the axis. The winding core cylinder 330 is a cylindrical cylinder. The cylinder and the round rod are rotatably connected by bearings to make the cylinder rotate smoothly. The rotatable winding core cylinder 330 is a rolling body rotation structure set on the winding core, which connects the gaps between the two cylindrical cylinders at the two ends of the two inner C ring gaps respectively, thus forming the winding core gap 310.

[0054] The first retaining frame 1 is composed of a first retaining frame inner C ring 121 , a connecting rod 123 , a first retaining frame outer C ring 122 , 10 round rods of the same shape (the round rods are blocked by the first retaining frame cylinder 120 and are not shown in the figure) and 10 first retaining frame cylinders 120 . The first retainer inner C ring 121 corresponds to the gap of the first retainer outer C ring 122 through the connecting rod 123 and is connected concentrically. Ten round rods are installed between the first retainer inner C ring 121 and the first retainer outer C ring 122. One end of the inner ring of the round rod is slightly higher than the end of the outer ring and is installed radially. The round rods are provided with a first retainer cylinder 120 that can rotate with the round rod as the axis. The first retainer cylinder 120 is a truncated cone cylinder. The cylinder and the round rod are rotatably connected by a bearing to make the cylinder rotate smoothly. The rotatable first retainer cylinder is a rolling body rotation structure provided on the retainer. The thin end of the truncated cone cylinder faces the inner ring and the thick end faces the outer ring to form a retainer with a gap. The restraining surface of the retainer for the wire coil is a plane. The gaps between the two first retainer cylinders at both ends of the inner and outer C ring gaps are connected to form the first retainer gap 110. The first retainer 1 is fixedly connected to the winding core 3 basically vertically through the first retainer inner C ring 121.

[0055] The second retaining frame 2 is composed of a second retaining frame inner C ring 221, 8 rotating connection mechanisms 240, 8 round rods 260 of the same shape and 8 second retaining frame cylinders 220. The 8 rotating connection mechanisms 240 are evenly distributed on the second retaining frame inner C221 ring, and each rotating connection mechanism 240 is composed of a square block A245, a square block B246, a locking tongue 242, a rotating shaft 243, a nut 244 and a limit block 247. Square blocks A245 and square blocks B246 are fixed on the second retaining frame inner C221 ring, as shown in FIG. Figure 7 As shown, the two blocks are arranged relative to each other in a slot shape, and a locking mechanism is provided on the block A245, whose locking tongue 242 can be extended into or out of the slot, and the two blocks are provided with holes for matching the rotating shaft 243, and the front end of the round rod 260 is inserted into the slot, and the cross section of the front end of the round rod 260 is rectangular and has a through hole 2201, so that the through hole 2201 corresponds to the holes on the two blocks, and the rotating shaft 243 is passed through the corresponding through hole and tightened with the nut 244, so that the round rod 260 is rotatably connected with the C ring 221 in the second stop frame, and the round rod 260 is provided with a mechanism that can rotate with the round rod as the axis The movable second baffle frame cylinder 220 is a truncated cone-shaped cylinder. The cylinder and the round rod 260 are rotatably connected by a bearing to make the cylinder rotate smoothly. The rotatable second baffle frame cylinder 220 is a rolling body rotation structure arranged on the baffle frame. A limit block 247 is arranged outside the groove. When the round rod 260 is flattened, it is placed on the limit block 247. The height of the limit block 247 is adjusted so that the constraint surface of the second baffle frame composed of 8 truncated cone-shaped cylinders becomes a plane, and then the lock tongue 242 extends out to lock the round rod 260 to prevent rotation.

[0056] The first stop frame 1 is provided with three transmission frame connecting screws 180, which can be used together with nuts to fix the new winding wheel on the transmission frame of the winding machine (not shown in the figure). As the transmission frame driven by the motor rotates, the new winding wheel also rotates.

[0057] When winding, the device presents Figure 5 state, that is, the winding core 3, the first stop frame 1 and the second stop frame 2 form a winding surface; the first stop frame notch 110, the second stop frame notch 210 and the winding core notch 310 form a winding groove; the head end of the wire is fixed on any winding core cylindrical barrel, of course, it is best to fix it near the end of the barrel next to the winding groove, and then start the motor to drive the winding wheel to rotate, and at the same time swing the wire to make the wire evenly wound on the winding core 3 and constrained by the first stop frame 1 and the second stop frame 2 to form a wire coil; after winding, cut the tail end of the wire, and stick the tail end on the wire coil, and release the wire fixed on the winding core 3. The head end of the wire on the core 3 is also pasted and fixed on the wire coil, and then the winding wheel is kept stationary, and the wire coil is manually rotated with the winding core as the fixed axis. Because of the rotation structure on the winding core and the retaining frame, the wire coil is easy to be rotated. The wire coil is rotated to the required place and the cable tie is passed through the winding groove to complete the through-core bundling of the wire coil, or the worker first uses a film tape to pass through the winding groove to through-core and wrap a small section, and after completing a small section, the wire coil is rotated and wrapped again. In this way, the entire wire coil can be through-core and wrapped continuously. After bundling is completed, the locking tongue 242 is retracted, and the second retaining frame cylinder 220 is rotated and retracted to deform the retaining frame, like Figure 6 In that case, the second retaining frame 2 is disassembled and the bundled wire coil is taken out.

[0058] Further optimization can be performed by replacing the cylindrical winding core body on the winding core 3 with a truncated cone-shaped body, with the thin end facing the second stop frame, thus forming a winding core with a thick end and a thin end that is approximately cylindrical, making it more convenient to remove the wire coil.

[0059] This embodiment is a winding machine with a new winding wheel equipped with a wrapping machine, such as Figure 8 , 9 As shown in Figures 10, 11, 12, 13, 14 and 15, the entire winding machine includes a frame, a winding power device, two transmission frames, a new winding wheel, a wire arrangement device, a wrapping machine, etc.

[0060] The frame 700 of this embodiment is a rectangular parallelepiped frame, and all parts of the winding machine are arranged and installed on it.

[0061] The present embodiment provides a new type of winding wheel for the winding machine, the new type of winding wheel comprises a winding core 3, a first baffle 1, and a second baffle 2, the first baffle 1 is connected to one end of the winding core 3, the second baffle 2 is matched with one end of the winding core 3, the first baffle 1 and the second baffle 2 are respectively substantially perpendicular to the winding core 3 (the axis of the winding core is substantially perpendicular to the restraining surfaces of the two baffles for the wire coil), the second baffle 2 can be detached, the first baffle 1 and the second baffle 2 and the winding core 3 have aligned notches to form a winding groove, and the characteristic is that the winding core 3 is provided with a rolling body rotation structure.

[0062] The winding core 3 is composed of 8 round rods (the round rods are blocked by the winding core cylinder 330 and are not marked in the figure) and 8 winding core cylinders 330. The first retaining frame 1 is composed of an arc ring A140, an arc ring B150, 6 round rods (the round rods are blocked by the first retaining frame cylinder 120 and are not marked in the figure) and 6 first retaining frame cylinders 120. The round rods of the winding core 3 are divided into two groups, each with 4 rods, which are vertically connected to the arc ring A140 and the arc ring B150 of the first retaining frame, and the two arc rings are respectively connected to the round rods of the first retaining frame 1 in the horizontal direction (each arc ring is connected to 3 rods), so that the first retaining frame 1 and the winding core 3 are connected together through two arc rings.

[0063] The winding core 3 is provided with a rotation-enhancing structure. Specifically, the round rod of the winding core 3 is provided with a winding core cylinder 330 which can rotate with the round rod as the axis. The winding core cylinder 330 is a cylindrical cylinder. The cylinder and the round rod are rotatably connected by a bearing to make the cylinder rotate smoothly. The rotatable winding core cylinder 330 is a rolling body rotation-enhancing structure.

[0064] The first baffle frame 1 is also provided with a rotation structure. The round rod of the first baffle frame 1 is slightly tilted downward. The round rod is provided with a first baffle frame cylinder 120 that can rotate with the round rod as the axis. The first baffle frame cylinder 120 is a truncated cone-shaped cylinder with the thin end facing inward. The cylinder and the round rod are rotatably connected by a bearing to make the cylinder rotate smoothly. The rotatable truncated cone-shaped cylinder is the rolling body rotation structure. The round rod is slightly tilted downward so that the constraint surface of the first baffle frame becomes a plane. The rolling body of the first baffle frame 1 is equipped with a power source, such as Fig.12 The drum motor 161 shown is fixed on the arc ring A140, and drives the first baffle drum 120 to rotate through the PU belt 162. The drum motor is also installed on the arc ring B150, so that the first baffle drum 120 can provide power for the coil to rotate relative to the core as a fixed axis.

[0065] The two arc rings are connected to the first transmission frame 500 (the first transmission frame 500 includes an upper ring, a lower ring, and four connecting rods. There are two pillars 514 on the inner side of the upper ring for connecting the ball nut seat, and a first shaft 510 extending downward at the center of the lower ring) through the ball screw module A520 and the ball screw module B620. Since the connection methods are the same, we will only describe one of them in detail. Fig.10 The arc ring A140 is connected to the shaft end of the three-axis cylinder A130 through the connecting piece 132. The three-axis cylinder A130 is fixed on the ball screw module base 524 of the ball screw module A520. The ball nut seat 521 on the ball screw module A520 is fixed on the support 514 of the first transmission frame 500. When the lifting motor 525 drives the ball screw 523 to rotate, it also drives the ball nut seat 521 and the ball screw 523 to move relative to each other. Because the ball nut seat 521 is fixed, the ball screw module base 524 will move up and down, so the three-axis cylinder A130 fixed thereon also moves up and down. The two arc rings are set to rise and fall synchronously and remain on a horizontal plane, so that the six first block frame cylinders 120 in the horizontal direction of the two arc rings form two first block frame constraint surfaces. When the shafts of the two three-axis cylinders (three-axis cylinder A130, three-axis cylinder B190) are extended to the maximum stroke, the two arc rings are distributed along the circumference with the same point as the center, so that the winding core 3 appears to be approximately cylindrical. When the shafts of the two three-axis cylinders are retracted, the winding core is retracted, so that the winding core is a retractable winding core.

[0066] The second baffle frame 2 is composed of a C-shaped ring 230, 9 round rods (the round rods are blocked by the second baffle frame cylinder 220 and are not marked in the figure) and 9 second baffle frame cylinders 220. The C-shaped ring 230 is connected to 9 round rods slightly tilted upward in the horizontal direction. The round rod is provided with a second baffle frame cylinder 220 that can rotate with the round rod as the axis. The second baffle frame cylinder 220 is a truncated cone-shaped cylinder with a thin end facing inward. The cylinder and the round rod are rotatably connected by bearings to make the cylinder rotate smoothly. The rotatable second baffle frame cylinder 220 is a rolling body rotation structure. The round rod is slightly upward so that the constraint surface of the first baffle frame becomes a plane. The C-shaped ring 230 is connected to the second transmission frame 600 (the second transmission frame 600 includes an upper ring, 4 connecting rods, and a second shaft 610 extending upward at the center of the upper ring) through 4 connecting rods of the second transmission frame 600.

[0067] There is a gap between the arc ring A140 and the arc ring B150, so that a corresponding gap is formed on the winding core 3 and the first baffle 1. This gap is the winding core notch 310 and the first baffle notch 110. The gap at the opening of the C-ring 230 and the second baffle cylinder 220 is the second baffle notch 210. The second baffle notch 210 is aligned with the winding core notch 310 and the first baffle notch 110 to form a winding groove.

[0068] like Fig.10 As shown, a gap filling structure is also installed at one end of the arc ring A140 to fill the gap 310 of the winding core and the gap 110 of the first stop frame. The filling bracket 170 is L-shaped, one end of which is rotatably connected to the arc ring A140 and the other end is connected to the filling cylinder 349 and the filling stop frame rod 171. The filling cylinder 349 is the same structure and size as the winding core cylinder 330. When winding the wire, the filling stop frame rod 171 is lifted up to the same plane as the first stop frame constraint surface under the drive of the lifting rod motor 174, and then the filling motor 173 drives the filling bracket 170 to rotate so that the filling cylinder 349 and other winding core cylinders 330 together form an approximately cylindrical winding core, as shown in FIG. Figure 8 As shown, the gaps between the first stop frame 1 and the winding core 3 are filled.

[0069] The winding power device is composed of a power source (winding motor 710), a speed reduction mechanism (speed reducer 711), a transmission shaft 720, etc. The upper and lower ends of the transmission shaft 720 are rotatably connected to the frame 700 through bearings. The upper end of the transmission shaft 720 is connected to the winding motor 710, and the winding motor 710 drives the transmission shaft 720 to rotate through the speed reducer 711. The lower part of the first transmission frame 500 has a first shaft 510, and the center of the first shaft 510 is hollow, and gas and electricity pipelines can pass through the hollow. From top to bottom, the first shaft 510 first passes through the first bearing 532 and the first bearing seat 530 (such as Fig.13 As shown in the figure, the first shaft 510 is rotatably connected to the frame 700 (the first bearing seat 530 is fixedly connected to the frame 700 by a four-leg bracket 531), and then a first driven wheel 511 is provided on the first shaft 510, and the first driven wheel 511 is belt-drivenly connected to the first driving wheel 721 on the transmission shaft 720 through a tensioned first belt 512. Finally, the first shaft 510 is connected to the mover end of the gas-electric slip ring 513, and the stator end of the gas-electric slip ring 513 is fixed on the frame 700, and the compressed gas, electricity and control signal can be introduced into the first rotating frame 500 through the hollow of the first shaft 510. A second shaft 610 is provided on the upper part of the second transmission frame 600 so as to be rotatably connected to the frame 700 through a second bearing 614 and a second bearing seat 615 (the inner ring of the round nut 613 is fastened to axially fix the second bearing), and a second driven wheel 611 is provided on the second shaft 610. The second driven wheel 611 is belt-drivenly connected to a second driving wheel (not shown in the figure) on the transmission shaft 720 through a tensioned second belt 612. The first shaft 510 and the second shaft 610 are on the same axis, and the first driving wheel 721 and the second driving wheel (not shown in the figure) are of equal size, and the first driven wheel 511 and the second driven wheel 611 are of equal size, so the first transmission frame 500 and the second transmission frame 600 can rotate synchronously driven by the winding motor 710.

[0070] The wire arranging device 800 can make the wire swing back and forth evenly between the two baffles of the winding wheel, so that the wire is evenly wound on the winding wheel layer by layer. The wire arranging device is an existing mature technology and will not be described in detail here.

[0071] When the winding machine of this embodiment is winding the wire, Figure 8 As shown, the shafts of the two three-axis cylinders (three-axis cylinder A130 and three-axis cylinder B190) extend to the maximum stroke so that the winding core 3 presents an approximately cylindrical shape. The first stop frame 1 and the winding core 3 cooperate with the second stop frame 2 under the synchronous lifting of the ball screw module A520 and the ball screw module B620, so that the second stop frame 2 can constrain the wire on the winding core 3 during winding. The winding core gap 310 is filled by the filling cylinder 349, and the first stop frame gap 110 is filled by the filling stop frame rod 171. After the wire head passes through the wire arrangement device 800, it is clamped by the finger cylinder 172 installed on the filling bracket 170. Then the winding motor 710 drives the transmission shaft 720 to rotate, and then drives the first stop frame 1 and the winding core 3 and the second stop frame 2 to rotate synchronously through the first transmission frame 500 and the second transmission frame 600. The wire arrangement device 800 swings the wire up and down to make the winding uniform. After the winding is completed, the wire forms a coil. The winding motor 710 stops working and the entire winding wheel is stationary.

[0072] Next, the film tape is wound around the core and the wire coil is wound. The wire head held by the finger cylinder 172 is released. The filling motor 173 drives the filling bracket 170 to rotate so that the winding core gap 310 and the first stopper gap 110 are exposed. The lifting motor 174 works to make the filling stopper rod 171 droop to leave the working space required for winding. Fig.14 As shown, the wrapping machine 900 moves toward the center of the coil, and stops when the film winding mechanism 910 of the wrapping machine penetrates into the inner space of the coil through the winding groove, and starts the wrapping machine 900. At the same time, the drum motor 161 is started to drive the first stop frame drum 120 to rotate, so that the coil rotates in the same direction as the winding direction, and realizes the wrapping while passing through the center. After the wrapping is completed, the wrapping machine 900 and the drum motor 161 are stopped at the same time, and the tail end of the wire is cut off, and the wrapping machine 900 withdraws the coil. The wrapped coil is still constrained on the winding wheel. First, start the lifting motors of the ball screw module A520 and the ball screw module B620 to synchronously lower and move the first frame 1, the winding core 3 and the coil thereon away from the second frame 2, that is, the second frame 2 is disassembled; then retract the two three-axis cylinder shafts (three-axis cylinder A130 and three-axis cylinder B190), and the winding core 3 is reduced; after completing the above two actions, the packaged coil can be easily taken out from the new winding wheel.

[0073] By replacing the wrapping machine in the present embodiment with a cable tie machine, automatic cable tie threading and bundling can be completed.

[0074] For this embodiment, additional configuration is as follows Fig.15 The wire reel drive and rotation device shown in the figure is connected to the frame 700 through a bracket 921. One end of the bracket 921 is connected to the upper end of the frame 700, and the other end is connected to the nut seat 922. Usually, the power roller 920 is away from the winding wheel and does not interfere with other operations on the winding machine. When it is necessary to bundle the wound wire reel, the motor 924 rotates to drive the screw rod 923 to rotate. Since the nut seat 922 is fixed to the frame 700 by the bracket 921, the base 925 will carry the two power rollers 92 0 approaches and contacts the outer curved surface 402 of the wire roll, and a motor is installed in the power roller 920, which enables the power roller 920 to rotate around its own axis, thereby rotating the wire roll by contacting and rubbing the outer curved surface 402 of the wire roll (the drum motor 161 in this embodiment can be started at the same time to provide power for the rotation of the wire roll, and of course, the drum motor 161 and the PU belt 162 can also be removed and only the power of the power roller 920 can be used). After bundling is completed, the motor 924 rotates in the opposite direction to move the power roller 920 away from the winding wheel.
