[0002] Polyester heat shrink tubing, also known as PET heat shrink tubing, is mainly used for heat-resistant insulation and mechanical protection of solder joints, connectors, heating elements, capacitors, relays, etc. During production, several cut film sheets are rolled into a tubular shape, and then one end is ultrasonically welded closed. No glue is needed, and manual rolling is also unnecessary.

After being cut into multiple pieces, multiple film sheets are simultaneously wound into tubes by a winding device. Then, multiple tubes are simultaneously ultrasonically welded. Therefore, a fast and stable tube winding device is needed to adapt to the rapid mass production of glue-free insulating sleeves. Summary of the Invention

The top plate and the bottom plate are fixedly connected by a support column, and the movable plate is located between the top plate and the bottom plate and is slidably connected to the support column.

[0009] The second power unit drives the movable plate to move along the length of the support column. The movable plate is connected to the crossbeam through a connecting plate. A plurality of the pressing heads are arranged on the side of the crossbeam facing the mandrel.

[0012] An installation groove is provided at the bottom of the vertical plate, and a belt is provided through the installation groove on the multiple vertical plates, with the pressing head abutting against the belt.

[0013] Furthermore, a first gear is coaxially arranged at one end of the mandrel, and the first gears on two adjacent mandrels mesh with each other. The first power device includes a first motor and a second gear that rotates coaxially with its output shaft. The second gear meshes with the first gear on any of the mandrels.

[0014] Furthermore, the second transmission assembly includes a mounting plate and a second motor, a first pulley, a first lead screw, a first guide rail, and a limiting seat disposed thereon. The first lead screw is arranged parallel to the first guide rail. The second motor drives the first lead screw to rotate through the first pulley. One end of the first lead screw is rotatably connected to the limiting seat.

[0015] A first slider is provided at the bottom of the mounting plate, and a threaded part and a second slider are provided at the bottom of the mounting base. The threaded part is screwed to the first lead screw, and the second slider is slidably connected to the first guide rail.

[0016] Furthermore, a limiting plate is provided on the limiting seat corresponding to the tube winding assembly, and limiting holes are provided on the limiting plate corresponding to the plurality of mandrels.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] like Figures 1 to 9The thin film winding device shown includes a base 1 and a first transmission assembly 2, a second transmission assembly 3, a winding assembly 4, and a pressing assembly 5 disposed thereon. The pressing assembly 5 is disposed on the winding assembly 4, and the winding assembly 4 is connected to the first transmission assembly 2 through the second transmission assembly 3. The first transmission assembly 2 is disposed on the base 1 and can drive the second transmission assembly 3 to move in a first direction. The second transmission assembly 3 can drive the winding assembly 4 to move in a second direction. The first direction and the second direction are perpendicular to each other. The winding assembly 4 includes a mounting base 41 and a first power device 42 and a plurality of mandrels 43 disposed thereon. The first power device 42 synchronously drives the plurality of mandrels 43 to rotate. The pressing assembly 5 includes a support frame 51 and a second power device 52 and a plurality of pressing heads 53 disposed thereon. The second power device 52 synchronously drives the plurality of pressing heads 53 to move closer to or away from the mandrels 43.

[0038] In this application, the first transmission component 2 drives the tube winding device to move along the production line direction, and the second transmission component 3 drives the tube winding device to clamp the film sheet and feed the sleeve to the welding device or the cutting device. In the tube winding device, the tube winding component 4 cooperates with the tube pressing component 5 to wind the clamped film sheet into a tube.

[0039] During the tube winding process, the first power device 42 synchronously drives multiple mandrels 43 to rotate one side of the film sheet, while the second power device 52 synchronously drives multiple pressing heads 53 to press against the mandrels 43. As the mandrels 43 drive the film sheet to rotate, the pressing heads 53 can prevent the side of the film sheet away from being clamped by the mandrels 43 from rotating with the mandrels 43. During the rotation of the mandrels 43, the film sheet wrapped around the outer ring of the mandrels 43 can be pressed and fixed by the pressing heads 53. This facilitates the feeding of the rolled-up tubular film into the welding device for ultrasonic sealing of the outer end, and after sealing, it is fed into the cutting device for stable cutting.

[0040] Multiple mandrels 43 are arranged in parallel, and multiple pressing heads 53 are also arranged in parallel corresponding to the mandrels 43. The multiple mandrels 43 and pressing heads 53 are driven by the first power device 42 and the second power device 52 respectively to achieve synchronous movement of multiple thin film sheets, thereby improving production efficiency.

[0041] In the crimping assembly 5 described in this application, such as Figure 5As shown, the support frame 51 is mounted on the mounting base 41 and includes a top plate 511, a movable plate 512 and a bottom plate 513 arranged in parallel. The top plate 511 and the bottom plate 513 are fixedly connected by a support column 514. The movable plate 512 is located between the top plate 511 and the bottom plate 513 and is slidably connected to the support column 514. The second power device 52 drives the movable plate 512 to move along the length of the support column 514. The movable plate 512 is connected to the crossbeam 516 through a connecting plate 515. Multiple pressing heads 53 are arranged on the side of the crossbeam 516 facing the spindle 43.

[0042] The second power unit 52 can be a vertically arranged cylinder, which is fixed on the top plate 511. Its output shaft is connected to the movable plate 512. The movable plate 512 is movably connected to multiple support columns 514 around its perimeter to ensure that the second power unit 52 drives several downward pressure heads 53 to move smoothly.

[0043] See further Figure 5 As shown, the pressing head 53 includes a rod 531 and a head 532. The rod 531 passes through and is slidably connected to the crossbeam 516. A return spring 54 is sleeved on the rod 531, and the two ends of the return spring 54 abut against the crossbeam 516 and the head 532, respectively. During the process of the second power device 52 driving the pressing head 53 to press against the mandrel 43, by setting the return spring 54 between the crossbeam 516 and the head 532, and setting the pressing head 53 as a movable pressing head, it can be ensured that the pressure applied by the pressing head 53 to the mandrel 43 is just enough to press the coiled tube, avoiding excessive force that could damage the mandrel 43.

[0044] As another preferred embodiment of the above-mentioned pressure tube assembly 5, such as Figure 5 and Figure 6 As shown, multiple vertical plates 55 are arranged side by side on the crossbeam 516, and the pressing head 53 is located between two adjacent vertical plates 55; an installation groove 551 is provided at the bottom of the vertical plate 55, and a belt is provided through the installation groove 551 on the multiple vertical plates 55, and the pressing head 53 abuts against the belt.

[0045] The pressing head 53 is pressed against the mandrel 43 by a belt, avoiding direct contact between the hard pressing head 53 and the hard mandrel 43. By setting the belt, the wear of the pressing head 53 and the mandrel 43 during repeated pressing is reduced, extending the service life of both, and at the same time, the wear of the sleeve is also avoided.

[0046] In the tube assembly 4 disclosed in this application, such as Figure 3 and Figure 4As shown, a first gear 431 is coaxially arranged at one end of the spindle 43. The first gears 431 on two adjacent spindles 43 mesh with each other. The first power device 42 includes a first motor 421 and a second gear 422 that rotates coaxially with its output shaft. The second gear 422 meshes with the first gear 431 on any spindle 43.

[0047] Rotational transmission among multiple mandrels 43 arranged in parallel is achieved by a first gear 431 set at one end of the mandrel 43. During the process of winding the film sheet into a tube, the rotational direction of the mandrel 43 is not required. Therefore, the second gear 422 on the first motor 421 only needs to mesh with any of the first gears 431 according to the installation conditions of the first motor 421 to achieve synchronous rotation of multiple mandrels 43.

[0048] Furthermore, a clamping groove 432 is provided at the end of the mandrel 43 away from the first gear 431. The clamping groove 432 is radially penetrating the mandrel 43 and extends axially along the mandrel 43. To facilitate the clamping of the film sheet by the mandrel 43, an initial clamping position of the mandrel 43 is set so that the clamping groove 432 is vertically penetrating the mandrel 43, which facilitates the clamping of the film sheet.

[0049] In the second transmission assembly 3 disclosed in this application, such as Figure 7 As shown, the second transmission assembly 3 includes a mounting plate 31 and a second motor 32, a first pulley 33, a first lead screw 34, a first guide rail 35, and a limiting seat 36 disposed thereon. The first lead screw 34 is arranged parallel to the first guide rail 35. The second motor 32 drives the first lead screw 34 to rotate through the first pulley 33. One end of the first lead screw 34 is rotatably connected to the limiting seat 36. A first slider 311 is provided at the bottom of the mounting plate 31, and a threaded part 411 and a second slider 412 are provided at the bottom of the mounting seat 41. The threaded part 411 is screwed to the first lead screw 34, and the second slider 412 is slidably connected to the first guide rail 35.

[0050] like Figure 2 The transmission principle of the first transmission assembly 2 and the second transmission assembly 3 shown is the same. The first transmission assembly 2 includes a third motor 21, a second pulley 22, a second lead screw 23 and a second guide rail 24. The third motor 21 drives the second lead screw 23 to rotate through the second pulley 22. The second lead screw 23 is arranged parallel to the second guide rail 24. A screw sleeve 25 is provided on the second lead screw 23. The screw sleeve 25 is screwed to the second lead screw 23 and fixedly connected to the bottom of the mounting plate 31. The first slider 311 is slidably connected to the second guide rail 24.

[0051] As a preferred embodiment of this application, a limiting plate 361 is provided on the limiting seat 36 corresponding to the tube winding assembly 4, and a limiting hole 362 is provided on the limiting plate 361 corresponding to a plurality of mandrels 43. The tube winding assembly 4 moves along the second direction and can drive the mandrels 43 to pass through the limiting hole 362.

[0052] like Figure 8 As shown, the second transmission assembly 3 drives the winding assembly 4 to move along the second direction, so that the mandrel 43 passes through the limiting hole 362 on the limiting plate 361, which facilitates the mandrel 43 to clamp the film, and cooperates with the pressing assembly 5 to complete the winding and forming of the film sheet, as shown. Figure 9 As shown; after the film sheet is wound into a sleeve, it is sent to the welding device for ultrasonic sealing, and then sent to the cutting device for trimming to obtain the finished product. The second transmission component 3 drives the tube winding component 4 to retract in the second direction, so that the sleeve on the mandrel 43 falls off the mandrel 43 under the obstruction of the limiting plate 361 and is collected in the material box.

[0053] Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to this invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the invention as claimed.
