Description

Technical Field

[0001] This invention relates to a PVC fiber reinforced hose traction winding and packaging device, method, and hose, belonging to the technical field of PVC fiber reinforced hose production equipment. Background Technology

[0002] PVC fiber-reinforced hoses are hoses made by extruding PVC resin and synthetic fibers with plasticizers and other additives through a mold. They have wide applications in the chemical and pharmaceutical industries. To facilitate the transfer and transportation of PVC fiber-reinforced hoses, they need to be wound up and stored on a winding drum after production.

[0003] The existing patent, CN219044476U, describes a PVC fiber hose traction winding and packaging machine. This patent uses two sets of baffles to shield and limit the PVC fiber hose, preventing it from collapsing at both ends of the roll and ensuring reliability during the winding process. However, in practical use, it still has the following shortcomings: In practice, after the fiber hose is bundled on the roll, the nuts at the bottom of two sets of screws need to be rotated simultaneously to lower the sliding blocks and remove the PVC fiber reinforced hose. This makes disassembling the bundled PVC fiber reinforced hose cumbersome, time-consuming, and labor-intensive, affecting production efficiency. Furthermore, during the winding process, the PVC fiber reinforced hose is prone to uneven arrangement, causing inconvenience for subsequent use. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a PVC fiber reinforced hose traction winding and packaging device, method, and hose.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] According to one aspect of the present invention, a PVC fiber reinforced hose traction winding and packaging device is provided, comprising a lower fixed base, a vertical support frame mounted on the lower fixed base, a lifting adjustment component connected to the top of the vertical support frame via an L-shaped support frame, an inwardly expanding abutment limiting component connected to the lifting adjustment component mounted on the vertical support frame, a reciprocating sliding support component connected to one side of the lower fixed base, and a hose traction guide component mounted on the reciprocating sliding support component, the hose traction guide component comprising an inverted T-shaped support frame, a lower anti-slip guide member rotatably disposed on the inverted T-shaped support frame, and an inverted U-shaped hollow component mounted on the inverted T-shaped support frame. The bracket has a sliding bar connected to the top of the inverted U-shaped hollow bracket via an electric telescopic rod. Guide bars that cooperate with the sliding bar are provided on both sides of the inner wall of the inverted U-shaped hollow bracket. A sliding plate is connected to the bottom of the sliding bar via a connecting shaft. An upper guide wheel is rotatably installed on one side of the sliding plate. Side connecting blocks are provided on both sides of the connection between the inverted T-shaped support frame and the inverted U-shaped hollow bracket. Guide rollers are fixedly installed on the side connecting blocks. The lower anti-slip guide component includes a lower traction guide disc. One end of the lower traction guide disc is rotatably connected to the inverted T-shaped support frame via a bearing. A limit groove is opened on the lower traction guide disc. Elastic rubber gaskets are provided on both sides of the inner wall of the limit groove.

[0007] Furthermore, the lifting and adjusting assembly includes a vertical guide rail fixed on a vertical support frame, a movable support plate at one end of the vertical guide rail, and a sliding connection between the movable support plate and the vertical guide rail via a sliding block. An inner support bearing is embedded in the center of the movable support plate, and a hydraulic telescopic cylinder connected to the movable support plate is fixed on the vertical support frame.

[0008] Furthermore, the internal expansion contact limiting component includes a hollow support column that is fixedly inserted through the inner ring of the inner support bearing. A limit stop is fixedly installed on one side of the hollow support column. An adjustable inner movable column is movably installed inside the hollow support column. One end of the adjustable inner movable column is integrally connected to a positioning threaded column located outside the hollow support column. A limit threaded sleeve is fixed on the positioning threaded column. The other end of the hollow support column is connected to a drive motor, and the drive motor can be detachably installed on the vertical support frame.

[0009] Furthermore, the outer wall of the hollow support column is slidably fitted with a sliding sleeve, and several sliding adjustment grooves corresponding to the sliding sleeve are evenly opened on the hollow support column. A connecting block that passes through the sliding adjustment groove and is connected to the sliding sleeve is fixed on the adjustable inner movable column. Four sets of connecting frames are rotatably connected to the outer side of the sliding sleeve, and a support plate is rotatably connected to the other end of the connecting frame. An arc-shaped inner support plate is installed on the support plate.

[0010] Furthermore, the limiting plate is evenly provided with strip grooves, one end of the support plate is connected to a connecting block that moves through the strip groove, the other end of the connecting block is fixed with a guide limiting block, and guide pulleys are rotatably installed on both sides of the guide limiting block.

[0011] Furthermore, the reciprocating sliding support assembly includes a U-shaped support base, one end of which is fixedly mounted with a forward and reverse drive motor, and a sliding base is provided on the U-shaped support base. The output end of the forward and reverse drive motor is connected to a transmission screw threaded through the sliding base. Inside the U-shaped support base, on both sides of the transmission screw, there are guide posts that penetrate the sliding base. A support platform is fixedly mounted on the sliding base, and the support platform is connected and fixedly connected to the inverted T-shaped support frame.

[0012] According to another aspect of the present invention, a method of using a PVC fiber reinforced hose traction winding and packaging device is provided, specifically including the following steps:

[0013] S1: Before traction, first adjust the hose traction guide assembly according to the diameter of the PVC fiber reinforced hose, and put the take-up drum used to wind up the PVC fiber reinforced hose outside the inner expansion contact limit assembly to complete the preparation work before traction winding.

[0014] S2: During traction, the produced PVC fiber reinforced hose is passed through the hose traction guide assembly. The hose traction guide assembly guides the PVC fiber reinforced hose and finally connects it to the take-up drum sleeved outside the inner expansion contact limit assembly. The drive motor drives the whole drum to rotate, thereby realizing the winding operation.

[0015] S3: While the take-up drum is rotating, the reciprocating sliding support component enables the hose traction guide component to move slowly back and forth on it, so that the PVC fiber reinforced hose is evenly arranged and wound around the outside of the take-up drum during winding.

[0016] S4: After the winding operation is completed, the lifting and adjusting component drives the inner expansion type abutment limit component and the winding drum containing the PVC fiber reinforced hose to descend to the ground. Then, by loosening the limit threaded sleeve and driving the positioning threaded column to move in the opposite direction, the adjusting inner movable column moves in the opposite direction, thereby realizing the retraction of the inner expansion type abutment limit component. This allows the winding drum containing the PVC fiber reinforced hose to disengage from the other side of the limit baffle from the inner expansion type abutment limit component, thus completing the winding and packaging operation.

[0017] In addition, the present invention also provides a PVC fiber reinforced hose, including the PVC fiber reinforced hose pulled, wound and packaged by the above-mentioned PVC fiber reinforced hose traction winding and packaging device.

[0018] The beneficial effects of this invention are:

[0019] The lower fixed base, in conjunction with the vertical support frame, provides overall support for the equipment. The L-shaped support frame supports the lifting and adjusting assembly, which in turn drives the inner-expanding contact limiting assembly to move up and down, facilitating unloading after winding. The inner-expanding contact limiting assembly provides internal support positioning for different sizes of take-up drums and facilitates subsequent disassembly. The hose traction guide assembly, in conjunction with the reciprocating sliding support assembly, allows the hose traction guide assembly to move slowly left and right, ensuring that the PVC fiber reinforced hose is evenly wound around the take-up drum during winding. This invention facilitates unloading after winding, and the inner-expanding contact limiting assembly provides internal support positioning for different sizes of take-up drums and facilitates subsequent disassembly. Furthermore, it ensures even arrangement during PVC fiber reinforced hose winding, preventing the hose from tangling and facilitating subsequent use. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-7This invention provides a technical solution for a PVC fiber reinforced flexible hose traction winding and packaging device, including a lower fixed base 1, on which a vertical support frame 2 is installed. The lower fixed base 1, in conjunction with the vertical support frame 2, provides overall support for the device. A lifting and adjusting assembly 4 is connected to the top of the vertical support frame 2 via an L-shaped support frame 3. An inwardly expanding contact limiting assembly 5, connected to the lifting and adjusting assembly 4, is installed on the vertical support frame 2. The L-shaped support frame 3 supports the lifting and adjusting assembly 4, which in turn drives the inwardly expanding contact limiting assembly 5 to move up and down, facilitating unloading after winding. A reciprocating sliding support assembly 6 is connected to one side of the lower fixed base 1. The component 6 is equipped with a hose traction guide assembly 7, which includes an inverted T-shaped support frame 31. A lower anti-slip guide component 32 is rotatably mounted on the inverted T-shaped support frame 31. An inverted U-shaped hollow bracket 33 is mounted on the inverted T-shaped support frame 31. A sliding strip 35 is connected to the top of the inverted U-shaped hollow bracket 33 via an electric telescopic rod 34. Guide strips 36 that cooperate with the sliding strip 35 are provided on both sides of the inner wall of the inverted U-shaped hollow bracket 33. A sliding plate 38 is connected to the bottom of the sliding strip 35 via a connecting shaft 37. An upper guide wheel 39 is rotatably mounted on one side of the sliding plate 38. Side connecting blocks 40 are provided on both sides of the connection between the inverted T-shaped support frame 31 and the inverted U-shaped hollow bracket 33. A guide roller 41 is fixedly mounted on the side connecting block 40. By passing the PVC fiber reinforced hose through the channel formed between the lower anti-slip guide member 32 and the upper guide wheel 39, traction guidance is achieved while anti-slip effect is also achieved. The sliding bar 35 is driven by the electric telescopic rod 34 and moves up and down along the inner wall of the inverted U-shaped hollow bracket 33 under the guidance of the guide bar 36. The sliding bar 35 drives the sliding plate 38 to slide up and down synchronously through the connecting shaft 37, thereby realizing the adjustment of the distance between the upper guide wheel 39 and the lower anti-slip guide member 32 to accommodate PVC fiber hoses of different diameters. The internal expansion contact limit component 5 can provide internal support positioning for different specifications of take-up drums and facilitate subsequent disassembly. The hose traction guide component 7 is set up in conjunction with the reciprocating sliding support component 6, so that the hose traction guide component 7 can move slowly left and right on it, thereby evenly arranging and winding the PVC fiber reinforced hose outside the take-up drum during winding.

[0031] See Figure 2 The lifting and adjusting assembly 4 includes a vertical guide rail 8 fixed on the vertical support frame 2. One end of the vertical guide rail 8 is provided with a movable support plate 9, and the movable support plate 9 is slidably connected to the vertical guide rail 8 through a sliding block 11. An inner support bearing 10 is embedded in the center of the movable support plate 9. A hydraulic telescopic cylinder 12 connected to the movable support plate 9 is fixed on the vertical support frame 2. The movable support plate 9 is lowered by the hydraulic telescopic cylinder 12, and stable lifting and lowering is achieved with the cooperation of the vertical guide rail 8 and the sliding block 11.

[0032] See Figure 3-4 The internal expansion contact limiting assembly 5 includes a hollow support column 13 that is fixedly inserted through the inner ring of the inner support bearing 10. A limit stop plate 14 is fixedly installed on one side of the hollow support column 13. An adjustable inner movable column is movably installed inside the hollow support column 13. One end of the adjustable inner movable column is integrally connected to a positioning threaded column 15 located outside the hollow support column 13. A limit threaded sleeve 16 is fixed on the positioning threaded column 15. The other end of the hollow support column 13 is connected to a drive motor, and the drive motor is detachably installed on the vertical support frame 2 by bolts. A sliding sleeve 17 is slidably fitted on the outer wall of the hollow support column 13. The upper part is evenly provided with several sliding adjustment grooves 18 corresponding to the sliding sleeve 17, and the adjustable inner movable column is fixed with a connecting block that passes through the sliding adjustment groove 18 and is connected to the sliding sleeve 17. Four sets of connecting frames 19 are rotatably connected to the outside of the sliding sleeve 17. The other end of the connecting frame 19 is rotatably connected to the support plate 20. The support plate 20 is equipped with an arc-shaped inner support plate 46. The limiting plate 14 is evenly provided with strip grooves 21. One end of the support plate 20 is connected to a connecting block 22 that moves through the strip groove 21. The other end of the connecting block 22 is fixed with a guide limiting block 23, and guide pulleys 24 are rotatably installed on both sides of the guide limiting block 23. Driven by the motor, the entire internal expansion contact limiting assembly 5 can be rotated, thereby enabling the PVC fiber reinforced hose to be wound on the take-up drum. When installing the take-up drum, first, the take-up drum is placed outside the internal expansion contact limiting assembly 5. By manually pushing the adjustable inner movable column inward, the connecting block drives the sliding sleeve 17 to slide on the hollow support column 13. With the cooperation of the connecting frame 19, the support plate 20 is simultaneously driven to expand outward, thereby performing internal support contact limiting work on the take-up drum. The support plate 20 drives the guide limiting block 23 and guide pulley 24 to move on the limiting plate 14 through the connecting block 22, thereby achieving stable guidance and positioning of the support plate 20.

[0033] See Figure 5 The reciprocating sliding support assembly 6 includes a U-shaped support base 25. A forward and reverse drive motor 26 is fixedly installed at one end of the U-shaped support base 25. A sliding base 27 is provided on the U-shaped support base 25. The output end of the forward and reverse drive motor 26 is connected to a transmission screw 28 threaded through the sliding base 27. Guide posts 29 are provided on both sides of the transmission screw 28 inside the U-shaped support base 25, penetrating the sliding base 27. A support platform 30 is fixedly installed on the sliding base 27, and the support platform 30 is connected and fixed to the inverted T-shaped support frame 31. The forward and reverse drive motor 26 drives the transmission screw 28 to rotate. Under the guidance of the guide posts 29, the sliding base 27 drives the support platform 30 to reciprocate left and right, thereby driving the hose traction guide assembly 7 to reciprocate and adapt to the uniform arrangement work of the winding operation.

[0034] See Figure 7The lower anti-slip guide component 32 includes a lower traction guide disc 42. One end of the lower traction guide disc 42 is rotatably connected to the inverted T-shaped support frame 31 through a bearing 43. A limiting groove 44 is provided on the lower traction guide disc 42, and elastic rubber gaskets 45 are provided on both sides of the inner wall of the limiting groove 44. By using the limiting groove 44 in conjunction with the elastic rubber gaskets 45 on both sides, an anti-slip effect can be achieved when guiding the PVC fiber reinforced hose, preventing the PVC fiber reinforced hose from sliding out of the limiting groove 44.

[0035] This invention provides a method for using a PVC fiber reinforced hose traction winding and packaging device, specifically including the following steps:

[0036] S1: Before traction, first adjust the hose traction guide assembly 7 according to the diameter of the PVC fiber reinforced hose, and put the take-up drum for winding the PVC fiber reinforced hose outside the inner expansion contact limit assembly 5 to complete the preparation work before traction winding.

[0037] S2: During traction, the produced PVC fiber reinforced hose is passed through the hose traction guide assembly 7. The hose traction guide assembly 7 guides the PVC fiber reinforced hose and finally connects it to the take-up drum sleeved outside the inner expansion contact limit assembly 5. The drive motor drives the whole drum to rotate, thereby realizing the winding operation.

[0038] S3: While the take-up drum is rotating, the reciprocating sliding support component 6 enables the hose traction guide component 7 to move slowly back and forth on it, so that the PVC fiber reinforced hose is evenly arranged and wound around the outside of the take-up drum during winding.

[0039] S4: After the winding operation is completed, the lifting adjustment component 4 drives the inner expansion type abutment limit component 5 and the winding drum with PVC fiber reinforced hose to descend to the ground. Then, by loosening the limit thread sleeve 16 and driving the positioning thread column 15 to move in the opposite direction, the adjustable inner movable column moves in the opposite direction, so as to realize the retraction of the inner expansion type abutment limit component 5. Thus, the winding drum with PVC fiber reinforced hose is separated from the inner expansion type abutment limit component 5 from the other side of the limit baffle 14, and the winding and packaging operation is completed.

[0040] The present invention also provides a PVC fiber reinforced hose, comprising the PVC fiber reinforced hose pulled, wound, and packaged by the aforementioned PVC fiber reinforced hose traction winding and packaging device.

[0041] In use, the lower fixed base 1, together with the vertical support frame 2, provides overall support for the equipment. The L-shaped support frame 3 supports the lifting and adjusting component 4, which in turn drives the inner expansion contact limit component 5 to move up and down, facilitating unloading after winding. The inner expansion contact limit component 5 can provide internal support positioning for different specifications of take-up drums and facilitates subsequent disassembly. The hose traction guide component 7, together with the reciprocating sliding support component 6, allows the hose traction guide component 7 to move slowly left and right, so that during winding, the PVC fiber reinforced hose is evenly arranged and wound around the take-up drum. This invention facilitates unloading after winding, and the inner expansion contact limit component 5 can provide internal support positioning for different specifications of take-up drums and facilitates subsequent disassembly. Furthermore, during the winding of the PVC fiber reinforced hose, it can achieve even arrangement, thereby preventing the PVC fiber reinforced hose from tangling together and facilitating subsequent use.

[0042] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
