DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] In this embodiment, a PVC coil winding device is provided, which solves the problem of uneven coil winding by adjusting the tension during winding, thereby improving the coil winding quality.

[0021] like Figure 1-Figure 11 As shown, in some embodiments, the winding device of the PVC coil includes a frame 200, which serves as a supporting base for the entire device and provides support for the entire device. In particular, an end-sealing assembly 300 is installed inside the frame 200, wherein the main function of the end-sealing assembly 300 is to carry the reel assembly 600 to ensure its stable operation.

[0022] The end-sealing assembly 300 includes a first rotating mechanism 310 and a second rotating mechanism 320, which are symmetrically arranged and respectively installed at both ends of the roll assembly 600. Below the second rotating mechanism 320, a roll conveying assembly 500 is specially designed to achieve smooth movement of the roll assembly 600. By connecting the end-sealing assembly 300 with an external motor, the external motor drives the end-sealing assembly 300 to rotate, thereby driving the roll assembly 600 to rotate.

[0023] Specifically, the first rotating mechanism 310 includes a first rotating disk 311, on which two fourth through holes 312 are arranged, and the two fourth through holes 312 are symmetrically arranged. These through holes are connected to one side of the roller assembly 600 to ensure a stable connection between the components. The second rotating mechanism 320 includes a second rotating disk 321, on which two fixed cylinders 322 are arranged. These fixed cylinders 322 are arranged one by one corresponding to the fourth through holes 312 on the first rotating disk 311. The fixed cylinder 322 is slidably connected to the other side of the roller assembly 600 to achieve smooth movement of the roller assembly 600.

[0024] The reel assembly 600 includes a reel 630 and a transmission shaft 680. A male connection buckle 640 is provided at one end of the reel 630, and a female connection buckle 670 is provided at one end of the transmission shaft 680. The two connection components cooperate with each other to ensure a firm connection between the reel 630 and the transmission shaft 680. An end plate 610 is provided at the other end of the reel 630, and the end plate 610 is connected to the reel conveying assembly 500 to ensure smooth movement of the reel assembly 600. A third transmission gear 690 is provided at the other end of the transmission shaft 680, and the gear is connected to the external motor to drive the reel assembly 600 to reel the PVC coil.

[0025] The roller conveying assembly 500 is designed to drive the movement of the reel 630 .

[0026] Furthermore, the rack 200 is provided with two symmetrically arranged side walls, which are symmetrically arranged on both sides of the rack 200 to ensure the stability and symmetry of the device. Each side wall includes a support column 210, a support side plate 250 and a mounting plate 260. The support column 210 is arranged on the front side of the support side plate 250, and a mounting groove 220 is specially designed on the support column 210 to facilitate the installation and fixing of the adjustment assembly 800.

[0027] The supporting side plate 250 is provided with two first through holes 230 and a second through hole 240, wherein the first through hole 230 is arranged in front of the second through hole 240, and the two first through holes 230 are arranged up and down, and the pressing roller assembly 100 is connected to the first through hole 230. The second through hole 240 is provided with a step, and the mounting plate 260 is mounted on the outside of the second through hole 240, and a slide groove is formed between the mounting plate 260 and the second through hole 240, and the mounting plate 260 is configured to fix the end-sealing assembly 300.

[0028] The supporting side plate 250 is provided with two first through holes 230 and one second through hole 240. The two through holes are cleverly arranged at different positions of the supporting side plate 250 to meet different installation requirements. Specifically, the first through hole 230 is arranged in front of the second through hole 240, the two first through holes 230 are arranged up and down, and the pressure roller assembly 100 is arranged corresponding to the first through hole 230.

[0029] It should be noted that the first rotating mechanism 310 and the second rotating mechanism 320 are respectively installed in the second through holes 240 of the supporting side plates 250 on both sides, and are fixed to the supporting side plates 250 by the mounting plate 260. In this embodiment, the second through hole 240 is designed as a through hole with a step form, and the mounting plate 260 is fixedly connected to the supporting side plate 250 by bolts. In particular, the mounting plate 260 is designed to be annular, and the end-sealing assembly 300 and the supporting side plate 250 are fixed as a whole by using the mounting plate 260. At this time, a slide groove can be formed between the mounting plate 260 and the second through hole 240, and the first rotating mechanism 310 and the second rotating mechanism 320 can be rotated in the second through hole 240 through this slide groove.

[0030] Specifically, in this embodiment, two stations are set in the middle of the end-sealing assembly 300, namely, a coiling station and a discharging station. At the coiling station, the roller assembly 600 rotates to reel the PVC coil. After the reeling is completed, the cutting assembly cuts the PVC coil, and then the end-sealing assembly 300 rotates to rotate the reel assembly 600 that has been reeled to the discharging station. The roller conveying assembly 500 moves the reel 630 outward, so that the reel 630 is pulled out of the reeled PVC coil, and the reel is collected by the discharging assembly 400. After the discharging is completed, the roller conveying assembly 500 drives the reel 630 to move into the frame 200, so that the connecting male buckle 640 and the connecting female buckle 670 are engaged with each other, and the assembly of the roller assembly 600 is completed. At the same time, the roller assembly 600 reels the PVC coil at the coiling station, and this is repeated to improve the reeling efficiency of the PVC coil.

[0031] It is worth noting that before the PVC coil is wound, the conveying tension of the PVC coil will be adjusted by the adjustment component 800 and the pressure roller component 100 to ensure that the tension of the PVC coil at the winding station is constant, so that the wound PVC coil is neat and consistent, thereby improving the winding quality of the coil.

[0032] The split roller assembly 600 can quickly complete the operations of winding and unloading the PVC coil, and eliminates the paper tube in the middle of the PVC coil, reducing the paper tube loading process, thereby reducing the packaging cost of the PVC coil and improving production efficiency.

[0033] like Fig.10 and Fig.11 As shown, in some embodiments, the first rotating mechanism 310 further includes a first transmission gear 313, and the first transmission gear 313 is fixedly connected to the outer surface of the first rotating disk 311 by bolts. The first transmission gear 313 is connected to an external motor through transmission, so that the external motor drives the first transmission gear 313 to rotate, thereby driving the entire first rotating mechanism 310 to rotate.

[0034] In order to further enhance the stability of the first rotating mechanism 310 , a first annular protrusion 314 is provided on the outer edge of the first rotating disk 311 . The first annular protrusion 314 is slidably connected to the slide groove, and the first annular protrusion 314 plays a role of fixing and guiding.

[0035] like Figure 8 and Fig. 9 As shown, in some embodiments, the second rotating mechanism 320 includes a second transmission gear 325 and a fifth through hole 323. Specifically, the second transmission gear 325 and the fixed cylinder 322 are respectively disposed on both sides of the second rotating disk 321. In addition, the fifth through hole 323 penetrates the fixed cylinder 322 and the second rotating disk 321, so that the fifth through hole 323 can be slidably connected with the reel 630.

[0036] In order to further enhance the stability of the second rotating mechanism 320 , a second annular protrusion 326 is provided on the outer edge of the second rotating disk 321 . The second annular protrusion 326 can be slidably connected with the slide groove, and the second annular protrusion 326 also plays a fixing and guiding role.

[0037] In order to ensure the accurate position of the reel 630 during the winding process, elastic protrusions 324 are specially designed in the fifth through hole 323. These elastic protrusions 324 are configured to effectively limit the position of the reel 630 to prevent it from deviating during the winding process, thereby ensuring the smooth winding process and the neatness of the coils.

[0038] like Figure 6As shown, in some embodiments, the reel 630 is further provided with a slot 620 and a guide rod 650. The slot 620 is arranged on a side close to the end plate 610 and on the front side of the end plate 610. In particular, on a side away from the end plate 610, the side wall of the slot 620 is designed to be beveled, and the purpose of the beveled design is to facilitate the elastic protrusion block 324 to smoothly disengage from the slot 620 when the reel 630 is moved by the roller conveying assembly 500.

[0039] Specifically, when the roller conveying assembly 500 drives the reel 630 to move into the frame 200, when the reel 630 moves to the position, the elastic protrusion block 324 extends, and its top end is connected with the bottom of the slot 620. After the female buckle 670 and the male buckle 640 are engaged, the transmission shaft 680 rotates clockwise to realize the reeling operation of the PVC coil. After the reeling operation is completed, the roller conveying assembly 500 drives the reel 630 to move away from the frame 200, and the bevel pushes the elastic protrusion block 324 upward, so that the reel 630 is separated from the PVC coil.

[0040] In addition, the guide rod 650 is arranged on the front side of the connecting male buckle 640, and the transmission shaft 680 is provided with a guide groove 660, which is arranged on the front side of the connecting female buckle 670. The guide rod 650 and the guide groove 660 are arranged correspondingly. When connecting, the guide rod 650 is inserted into the guide groove 660, ensuring that the reel 630 and the transmission shaft 680 can be accurately connected.

[0041] like Figure 4 As shown, in some embodiments, the roller conveyor assembly 500 includes a conveying track 510, a conveying mechanism 520, a transmission mechanism 530 and a fixing block 540. Specifically, the transmission mechanism 530 is connected to the conveying track 510 to provide power for the conveying mechanism 520, and the conveying mechanism 520 slides along the conveying track 510, and the fixing block 540 is installed at the end of the conveying track 510 to provide support for the roller assembly 600.

[0042] The conveying track 510 includes a support platform 512 and a slide rail 513. A cavity is provided in the support platform 512, and a transmission screw 531 is installed in the cavity. The slide rail 513 is provided on the upper surface of the support platform 512. The slide rail 513 provides a moving track for the first slider 524 to ensure that the conveying mechanism 520 can move smoothly on the slide rail 513. A sixth through hole 511 is provided on one side of the support platform 512, and the transmission screw 531 passes through the sixth through hole 511 and is connected to the conveying motor 532. The other side of the support platform 512 is fixedly connected to the support side plate 250 to enhance the stability of the overall structure.

[0043] The fixing block 540 is provided with a supporting plate 541 and a connecting block 543 . A connecting column 542 is provided between the supporting plate 541 and the connecting block 543 . The connecting block 543 is fixedly connected to the supporting platform 512 .

[0044] The conveying mechanism 520 includes a clamping plate 521 and a first slider 524. A connecting groove 522 is provided in the middle of the clamping plate 521. The width of the connecting groove 522 is greater than the thickness of the end plate 610 and is used to connect with the end plate 610. A second telescopic column 523 is provided between the clamping plate 521 and the first slider 524, which is used to drive the clamping plate 521 to move upward. When the clamping plate 521 moves upward, the connecting groove 522 is connected to the end plate 610, and as the conveying mechanism 520 moves forward and backward, the reel 630 is driven to move forward and backward. Grooves are provided on both sides of the first slider 524. The grooves are designed to cooperate with the slide rail 513, so that the first slider 524 is meshed with the slide rail 513 to ensure that the conveying mechanism 520 can move smoothly on the slide rail 513. A threaded hole 525 is also provided on the first slider 524, which is used to be connected to the transmission screw 531 to ensure that the transmission screw 531 can drive the conveying mechanism 520 to move. In particular, an inward curvature is provided on the top of the clamping plate 521, which cooperates with the curvature of the reel 630 to ensure the stability of the reel 630 during movement.

[0045] It should be explained that the transmission mechanism 530 in this embodiment includes a transmission screw 531 and a conveying motor 532. The conveying motor 532 is fixedly connected to the supporting platform 512 and is responsible for driving the transmission screw 531 to rotate.

[0046] Finally, a support plate 541 and a connection block 543 are provided on the fixed block 540. A connection column 542 is provided between the support plate 541 and the connection block 543 to enhance the stability of the fixed block 540. The connection block 543 is fixedly connected to the support platform 512 to ensure that the fixed block 540 can be stably fixed on the conveying track 510.

[0047] like Figure 3 As shown, in some embodiments, a pressing roller assembly 100 and an adjusting assembly 800 are further provided in the frame 200. Specifically, the pressing roller assembly 100 is arranged in front of the adjusting assembly 800 to effectively adjust the tension of the PVC coil.

[0048] The pressure roller assembly 100 includes two pressure rollers, both ends of which are axially connected to the first through hole 230 respectively, so as to ensure that the pressure rollers can rotate flexibly. One end of the two pressure rollers is connected to an external motor transmission. The two pressure rollers rotate synchronously. The PVC coil passes through the middle of the two pressure rollers. While the pressure rollers rotate, the PVC coil is driven forward to achieve precise control of the conveying speed of the PVC coil. The moving speed is the same as the winding speed of the roller assembly 600, so as to ensure the stability of the winding process.

[0049] In addition, the adjustment assembly 800 is connected to the mounting groove 220 .

[0050] Furthermore, an adjusting roller 810 is provided in the adjusting assembly 800, and damping members 820 are respectively provided at both ends of the adjusting roller 810. The damping member 820 is used to adjust and locate the specific position of the adjusting roller 810 to ensure the tension of the PVC coiled material conveying.

[0051] Specifically, each damping member 820 includes a second slider 821. Springs 822 are installed on the upper and lower sides of the second slider 821, and the two ends of the springs 822 are fixedly connected to the mounting groove 220 and the second slider 821, respectively, so as to ensure that the springs 822 can provide stable elastic force during operation. The adjusting roller 810 can be accurately adjusted in position under the action of the springs 822. Through this structural design, the position of the adjusting roller 810 can be effectively controlled, thereby ensuring the tension of the PVC coil conveying and the winding quality.

[0052] The adjusting roller 810 is connected to the second slider 821 by a shaft connection, so as to ensure that the adjusting roller 810 can reduce the friction between the adjusting roller 810 and the PVC coil by rotating during the movement of the PVC coil.

[0053] like Figure 1 , Figure 2 and Figure 5 As shown, in some embodiments, the device in this embodiment further includes a discharge assembly 400 and two motor housings 700. The two motor housings 700 are respectively arranged on the left and right outer sides of the frame 200 to cover the external motors of the frame 200. In addition, the discharge assembly 400 is arranged in the frame 200, and the discharge assembly 400 is arranged below the end-sealing assembly 300. The discharge assembly 400 is configured to guide the rolled PVC coil to complete the discharge. Such a layout enables the discharge assembly 400 to effectively guide the rolled PVC coil to complete the discharge process. Through this design, not only the efficiency of discharge is improved, but also the safety and convenience of operation are ensured.

[0054] Furthermore, the unloading assembly 400 includes a fixed platform 410 and a movable platform 420. The fixed platform 410 is hinged to the movable platform 420, and a fixed column 460 is provided at the bottom of the fixed platform 410; A fixed column 460 is provided at one end of the movable platform 420, and a first telescopic column 450 is provided at the other end of the movable platform 420.

A connecting rod 430 is provided between the two fixed side panels 440, and the first telescopic column 450 is connected to the connecting rod 430.

[0055] The unloading assembly 400 includes a fixed platform 410 and a movable platform 420. Specifically, the fixed platform 410 and the movable platform 420 are connected together by a hinge, so that the movable platform 420 can rotate within a certain range.
