Description

Technical Field

[0001] This utility model relates to the field of flame-retardant winding tubes, and in particular to a wire clamping device for winding flame-retardant winding tubes. Background Technology

[0002] Flame-retardant spiral wound tube winding refers to drawing a certain length of flame-retardant spiral wound tube from the take-up drum and winding it around the take-up bracket, then cutting it off. Subsequently, the flame-retardant spiral wound tube on the take-up bracket is tied with straps or slip knots. The flame-retardant spiral wound tube winding process requires the use of a wire feeding device, a wire clamping and pressing device, and a take-up bracket, all of which are arranged in a straight line. The flame-retardant spiral wound tube is released from the take-up drum by the wire feeding device and limited by the wire clamping and pressing device. Then, the released flame-retardant spiral wound tube is wound up by the rotation of the take-up bracket. This is one of the important steps in the production and processing of flame-retardant spiral wound tube.

[0003] In the existing technology, the clamping device used for winding flame-retardant spiral wound tubes uses a clamp to hold the flame-retardant spiral wound tube. During the unwinding process, the flame-retardant spiral wound tube inevitably rubs against the clamp, which hinders the unwinding and easily wears down the surface of the flame-retardant spiral wound tube. Furthermore, for flame-retardant spiral wound tubes of different diameters, the size of the clamp needs to be manually adjusted. Therefore, there is an urgent need to propose a clamping device for winding flame-retardant spiral wound tubes to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a wire clamping and pressing device for flame-retardant winding tubes that facilitates clamping of different sizes of flame-retardant winding tubes and facilitates the release of flame-retardant winding tubes.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a wire clamping and pressing device for winding flame-retardant spiral tubes, the innovation of which is: including A wire clamping table; A wire clamping assembly is provided on a wire clamping platform. The wire clamping assembly includes a pair of wire clamping wheels provided above the wire clamping platform. The wire clamping wheels are horizontally arranged and have wire clamping grooves recessed towards the center of the wire clamping wheel on their outer circumferential walls. The cross-section of the wire clamping grooves is V-shaped. The two wire clamping wheels move closer or further apart under the drive of a horizontal drive mechanism. The clamping of the flame-retardant winding tube is achieved through the joint cooperation of the two wire clamping wheels. A pair of limiting components are arranged on both sides of the clamping wheel. The two limiting components are distributed on both sides of the clamping wheel along the conveying direction of the flame-retardant winding tube. The limiting components include a pair of limiting rollers distributed vertically. The flame-retardant winding tube is limited by the cooperation of the two limiting rollers.

[0006] Furthermore, the horizontal drive mechanism is as follows: a guide frame is installed on the upper surface of the wire clamping table. The guide frame is in the shape of a square. A pair of support frames are installed inside the guide frame. The wire clamping wheels are movably installed on the support frames. Under the drive of the two support frame drive components, they move closer or further away from each other, thereby realizing that the two wire clamping wheels move closer or further away from each other. The drive assembly includes a drive screw with two threads in opposite directions. A threaded sleeve is also installed on each of the two support frames, and the two threaded sleeves are respectively matched with the two threads on the drive screw. The drive screw is driven to rotate by an asynchronous motor installed on the wire clamping table, which causes the two support frames to move closer or further apart.

[0007] Furthermore, the connection between the wire clamping wheel and the support frame is as follows: a rotating shaft extending into the support frame is provided on the bottom surface of the wire clamping wheel, a rotating seat is provided at the bottom end of the inner wall of the support frame, a rotating groove is opened on the upper end surface of the rotating seat to accommodate the bottom end of the rotating shaft to be inserted and rotated, and a slewing bearing is provided between the rotating shaft and the support frame. The slewing bearing is installed on the support frame and located above the rotating seat.

[0008] Furthermore, a guide strip is provided on both sides of the inner wall of the guide frame, and guide grooves that cooperate with the two guide strips are also provided on both sides of the support frame.

[0009] Furthermore, a displacement sensor is also provided on the support frame, and the two displacement sensors are respectively located on the adjacent sides of the two support frames.

[0010] Furthermore, a heat dissipation vent is provided on the clamping platform, and a heat dissipation mesh is provided at the heat dissipation vent.

[0011] The advantages of this utility model are as follows: In this utility model, the flame-retardant winding tube is clamped by the cooperation of two horizontally moving clamping wheels. By adjusting the distance between the two clamping wheels, it is convenient to clamp flame-retardant winding tubes of different diameters, and the application range is wider.

[0012] In addition, the connection between the wire clamping wheel and the support frame is achieved by the cooperation of a rotating seat and a slewing bearing, which enables the wire clamping wheel to rotate freely relative to the support frame. Based on this, during the wire feeding process, the feeding of the flame-retardant winding tube drives the two wire clamping wheels to rotate, thereby reducing the friction on the outer surface of the flame-retardant winding tube and reducing the resistance during winding, thus enhancing the practicality of the wire clamping and pressing device for winding the flame-retardant winding tube.

[0013] The horizontal drive mechanism is designed to drive the support frame to move horizontally within the guide frame by using a double-threaded drive screw and a threaded sleeve. Only one asynchronous motor is needed to achieve synchronous reverse movement of the two support frames, reducing the drive, simplifying the structure, and lowering energy consumption.

[0014] The design of the guide strips in the guide frame and the guide grooves on the support frame serves two purposes: firstly, to guide the horizontal movement of the support frame within the guide frame and prevent it from deviating from its intended path; and secondly, to limit the relative position of the support frame and the guide frame, preventing the support frame from swaying or shifting during horizontal movement.

[0019] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0020] like Figures 1-4 The illustrated flame-retardant winding tube wire clamping device includes: A wire clamping platform 1 is a rectangular parallelepiped structure with a cavity inside for accommodating components or wiring. A heat dissipation vent is also provided on the platform, and a heat dissipation mesh 3 is installed at the vent. The combination of the heat dissipation vent and the heat dissipation mesh 3 facilitates heat dissipation for the components or wiring installed within the platform, while also reducing the entry of external fixed particles and impurities into the cavity of the platform.

[0021] A wire clamping assembly is provided on a wire clamping platform 1. The wire clamping assembly includes a pair of wire clamping wheels 46 provided above the wire clamping platform 1. The wire clamping wheels 46 are horizontally arranged and have wire clamping grooves recessed towards the center of the wire clamping wheel on the outer circumference of the wire clamping wheel 46. The cross-section of the wire clamping grooves is V-shaped. The two wire clamping wheels 46 move closer or further away from each other under the drive of a horizontal drive mechanism. The clamping of the flame-retardant winding tube is achieved through the joint cooperation of the two wire clamping wheels 46.

[0022] The horizontal drive mechanism is as follows: a guide frame 41 is installed on the upper end face of the wire clamping table 1. The guide frame 41 is directly fixed to the upper end face of the wire clamping table 1. The guide frame 41 is U-shaped. A pair of support frames 44 are installed inside the guide frame 41. The support frames 44 are also U-shaped, and the opening direction of the support frames 44 is perpendicular to the opening direction of the guide frame 41. The two support frames 44 move closer or further away from each other under the drive of a drive component.

[0023] The drive assembly includes a drive screw 47, which is movably mounted on a guide frame 41 via bearings on both sides. The drive screw 47 has two threads with opposite directions of rotation. A threaded sleeve 48 is also installed on each of the two support frames 44, with each sleeve corresponding to one of the threads on the drive screw 47. The drive screw 47 is driven to rotate by an asynchronous motor 49 mounted on the wire clamping table 1, causing the two support frames 44 to move closer or further apart. The horizontal drive mechanism uses the double-threaded drive screw 47 and the threaded sleeves 48 to drive the horizontal movement of the support frames 44 within the guide frame 41. Only one asynchronous motor 49 is needed to achieve synchronous reverse movement of the two support frames, reducing the drive required, simplifying the structure, and lowering energy consumption.

[0024] The wire clamping wheel 46 is movably mounted on the support frame 44, and the two wire clamping wheels 46 move closer or further apart by the horizontal movement of the support frame 44.

[0025] The connection between the clamping wheel 46 and the support frame 44 is as follows: a rotating shaft 45 extending into the support frame 44 is provided on the bottom surface of the clamping wheel 46. A rotating seat is also provided at the bottom end of the inner wall of the support frame 44. A rotating groove is opened on the upper end surface of the rotating seat to accommodate the bottom end of the rotating shaft 45 for insertion and rotation. A bearing is also provided between the rotating shaft 45 and the rotating groove. A slewing bearing is also provided between the rotating shaft 45 and the support frame 44. The slewing bearing is installed on the support frame 44 and located above the rotating seat. The slewing bearing is fixedly fitted onto the outer wall of the rotating shaft 45. The connection between the clamping wheel 46 and the support frame 44 is achieved by the cooperation of the rotating seat and the slewing bearing, thereby realizing the free rotation of the clamping wheel 46 relative to the support frame 44. Based on this, during the wire feeding process, the feeding of the flame-retardant winding tube drives the two clamping wheels 46 to rotate, thereby reducing the friction on the outer surface of the flame-retardant winding tube, thus reducing the resistance during winding and enhancing the practicality of the wire clamping and pressing device for winding the flame-retardant winding tube.

[0026] A guide strip is provided on both sides of the inner wall of the guide frame 41, and guide grooves that cooperate with the two guide strips are also provided on both sides of the support frame 44. The design of the guide strips in the guide frame 41 and the guide grooves on the support frame 44 serves two purposes: first, to guide the horizontal movement of the support frame 44 within the guide frame 41 and prevent the support frame 44 from deviating; second, to limit the relative position of the support frame 44 and the guide frame 41 and prevent the support frame 44 from swaying or moving horizontally.

[0027] A displacement sensor 50 is also provided on the support frame 44, and the two displacement sensors 50 are respectively located on the adjacent sides of the two support frames 44. A control machine 2 is also provided on one side of the clamping table 1. The control machine 2 is connected to the displacement sensor 50 and the asynchronous motor 49. It is used to receive the position signal of the displacement sensor 50, and determine the position of the two support frames 44 according to the position signal, thereby controlling the asynchronous motor 49 to perform the action and realize automatic control.

[0028] A pair of limiting components are arranged on both sides of the clamping wheel 46. These two limiting components are distributed along the conveying direction of the flame-retardant winding tube on both sides of the clamping wheel 46. Each limiting component includes a pair of vertically distributed limiting rollers 43. The two limiting rollers 43 work together to limit the flame-retardant winding tube. The two sides of the two limiting rollers 43 on the same side are respectively fixed to a mounting frame 42, which is located outside the guide frame 41. The two sides of the limiting rollers 43 are movably connected to the mounting frame 42 via bearings. A gap is left between the two limiting rollers 43 to allow the flame-retardant winding tube to pass through. Through the design of the limiting components on both sides, the two limiting rollers 43 serve to limit the passing flame-retardant winding tube, preventing it from slipping off.

[0029] Working principle: In use, firstly, according to the required diameter of the flame-retardant winding tube, start the asynchronous motor 49 on the clamping table 1, so that the asynchronous motor 49 drives the drive screw 47 to rotate, and through the cooperation of the two threaded sleeves 48, drives the two support frames 44 to move in opposite directions, thereby adjusting the distance between the two clamping wheels 46 according to the diameter of the flame-retardant winding tube, so as to clamp the flame-retardant winding tube later. Then, the flame-retardant winding tube led out from the take-up drum passes through the limiting roller 43, and then passes through the two clamping wheels 46 to clamp the tube. When passing through, it drives the two clamping wheels 46 to rotate, thereby reducing the frictional resistance when the flame-retardant winding tube is fed in. After passing between another pair of limiting rollers 43, it is wound up by the take-up bracket and cut to the required length.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
