Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment devices, in particular to a heat treatment device for a TCP coating line. Background Art

[0002] TCP is the abbreviation of thermoplastic composite pipe, and TCP coating line is mainly used to produce coatings on the surface of thermoplastic composite pipes. Thermoplastic composite pipes are composed of inner lining, thermoplastic composite reinforcement layer and outer coating. During the production of these coatings, in order to improve the properties of the coatings, the surface of the coatings is usually heat treated.

[0003] However, in the process of coating treatment in existing TCP coating line heat treatment equipment, since most coatings are thermoplastic materials, they will produce a certain amount of deformation when the temperature rises. If the deformation is not controlled, it is easy to affect the internal structure of the coating material, resulting in a decrease in the coating heat treatment effect. In addition, when the temperature inside the heat treatment device is controlled, it is usually achieved by adjusting the power of the electric heater. However, when the temperature inside the device needs to be lowered, this method will slow the cooling speed of the device because the device is in a semi-closed state and the heater continues to release heat. Utility Model Content

[0004] The purpose of the present utility model is to provide a heat treatment device for a TCP coated wire to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a heat treatment device for a TCP coating line, comprising a shell, a hydraulic cylinder is fixedly installed on the top of the shell, a frame is engaged with the output end of the hydraulic cylinder, and a plurality of second rollers are respectively installed on the bottom ends of the frames, a cavity is opened inside the shell, a feed port is opened on one side wall of the cavity, and a discharge port is opened on the other side wall of the cavity, a plurality of first rollers are arranged inside the cavity, and the outer walls of the first and second rollers are movably connected with the coating line belts, a slide box is provided at the bottom of the shell, an electric heater is installed inside the slide box, four sliders are engaged with the bottom end of the slide box, the bottom end of the shell is fixedly connected to a bottom plate, and two linear guide rails are fixedly installed on the top of the bottom plate.

[0006] Preferably, a wire mesh is embedded in the top of the sliding box, the electric heater is located below the wire mesh, and the interior of the sliding box is communicated with the interior of the cavity through the wire mesh.

[0007] Preferably, the frame is movably connected to the cavity via a hydraulic cylinder, and the second roller is movably connected to the first roller via the frame.

[0008] Preferably, a rotating motor is fixedly installed inside the housing, and a sprocket is engaged with the output end of the rotating motor and the shaft end of one of the first rollers.

[0009] Preferably, the outer walls of the two sprockets are engaged with a chain, and one of the first rollers is rotatably connected to the outer shell through the sprocket and the chain.

[0010] Preferably, the remaining first rollers are rotatably connected to the housing via coated belts.

[0011] Preferably, the slider is slidably connected to the linear guide rail, and the slide box is movably embedded in the shell through the linear guide rail.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. This TCP coating line heat treatment device, through the frame, cavity, first roller, second roller and hydraulic cylinder, allows the coated strip to move within the device by alternately rotating along the surfaces of the first roller and the second roller when it enters the device and is heated to a higher temperature. This keeps the coated strip surface in a state of controlled contact, thereby reducing the adverse effects of excessive deformation on the internal structure of the coating and lowering the probability of poor coating heat treatment effect.

[0014] 2. This heat treatment device for TCP coating lines uses linear guides, sliders, slide boxes, and a base plate. When the temperature inside the device needs to drop, the slider can drive the slide box to slide along the linear guide toward one end of the base plate, separating the electric heater structure in the slide box from the device casing. This prevents the heater from continuously emitting heat inside the device, thereby facilitating a rapid drop in the temperature inside the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc. should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0023] like Figures 1 to 4As shown, the heat treatment device for TCP coating line in this embodiment includes a shell 1, a hydraulic cylinder 2 is fixedly installed on the top of the shell 1, a frame 7 is engaged with the output end of the hydraulic cylinder 2, and a plurality of second rollers 13 are respectively installed on the bottom end of the frame 7, a cavity 17 is opened inside the shell 1, a feed port 3 is opened on one side wall of the cavity 17, a discharge port 18 is opened on the other side wall of the cavity 17, a plurality of first rollers 11 are provided inside the cavity 17, and the outer walls of the first rollers 11 and the second rollers 13 are movably connected with the coating line belt 12, a slide box 4 is provided at the bottom of the shell 1, an electric heater 15 is installed inside the slide box 4, four sliders 16 are engaged with the bottom end of the slide box 4, the bottom end of the shell 1 is fixedly connected to the bottom plate 6, and two linear guide rails 5 are fixedly installed on the top of the bottom plate 6.

[0024] Specifically, the function of the hydraulic cylinder 2 is to adjust the position of the frame 7 so that the frame 7 can drive the position of the second roller 13 in the cavity 17 to be flexibly adjusted, thereby facilitating the deformation control of the coating tape 12 wound on the surface of the second roller 13. The frame 7 is made of lightweight carbon steel material, which can reduce the load on the output end of the hydraulic cylinder 2. The surfaces of the first roller 11 and the second roller 13 are smooth and the lengths are the same. At the same time, the first roller 11 and the second roller 13 are staggered inside the cavity 17, so that the coating that passes around the surfaces of the first roller 11 and the second roller 13 is staggered. The wire belt 12 can be in a state of controllable deformation. The coated wire belt 12 is the outer coating of the TCP pipe. After completing the heat treatment, it needs to be welded to the outer wall of the TCP pipe. The interior of the slide box 4 is hollowed out so that the electric heater 15 can have space for installation and fixation. The slider 16 can realize the sliding of the slide box 4 on the linear guide rail 5. The function of the base plate 6 is to support the linear guide rail 5 and the slide box 4 that slides out along the linear guide rail 5. At the same time, the function of the linear guide rail 5 is to enable the slid-out slide box 4 to slide back into the outer shell 1 along a predetermined path, thereby facilitating the sliding of the slide box 4 inside the outer shell 1.

[0025] Furthermore, a wire mesh 14 is embedded in the top of the slide box 4, and the electric heater 15 is located below the wire mesh 14. The interior of the slide box 4 is connected to the interior of the cavity 17 through the wire mesh 14. The wire mesh 14 can keep the top of the slide box 4 in an open state. At the same time, the wire mesh 14 can intercept larger debris to prevent the debris from falling into the housing 1 when the slide box 4 slides out.

[0026] Furthermore, the frame 7 is movably connected to the cavity 17 through the hydraulic cylinder 2, and the second roller 13 is movably connected to the first roller 11 through the frame 7. When the frame 7 is moved by the hydraulic cylinder 2, it can slide up and down in the cavity 17, thereby adjusting the displacement of the second roller 13 in the vertical direction.

[0027] Furthermore, a rotating motor 8 is fixedly installed inside the housing 1, and a sprocket 9 is engaged with the output end of the rotating motor 8 and the shaft end of one of the first rollers 11. The sprocket 9 can engage with the chain 10, thereby realizing the driving of the chain 10 by the sprocket 9.

[0028] Furthermore, the outer walls of the two sprockets 9 are engaged with a chain 10, and one of the first rollers 11 is rotatably connected to the outer shell 1 through the sprocket 9 and the chain 10. After the sprocket 9 is driven to rotate by the chain 10, it can drive the first sprocket 9 at the discharge port 18 to rotate, thereby driving the coated wire belt 12.

[0029] Furthermore, the remaining first rollers 11 are rotatably connected to the outer shell 1 through the coated belt 12. After being driven by the first roller 11, the coated belt 12 can slide along the surfaces of the remaining first rollers 11 and the second roller 13, thereby realizing the rotation of the first roller 11 in the outer shell 1.

[0030] Furthermore, the slider 16 is slidably connected to the linear guide 5, and the slide box 4 is movably embedded in the shell 1 through the linear guide 5. The slide box 4 can slide along the linear guide 5 through the slider 16, thereby realizing the separation of the slide box 4 and the shell 1, so that a larger opening appears at the bottom of the shell 1, which is conducive to the rapid dissipation of heat in the shell 1, thereby accelerating the cooling speed of the device.

[0031] The method of using this embodiment is as follows: before using the TCP coating line heat treatment device, it is necessary to first connect the device to an external power supply, and then the coating tape 12 can be passed through the feed port 3, and then passed through the first roller 11 and the second roller 13 in sequence, and then passed through the discharge port 18, and then the hydraulic cylinder 2 is started, so that the output end of the hydraulic cylinder 2 drives the frame 7 to move up and down in the cavity 17, and drives the second roller 13 to move up and down in the cavity 17, so that the second roller 13 is staggered between the first roller 11, and finally the axial ends of the second roller 13 and the first roller 11 are on the same horizontal line, and then the electric heater 15 in the slide box 4 can be started so that the electric heater The heater 15 starts to heat the inside of the slide box 4, and then the heated air in the slide box 4 will pass through the screen 14 into the cavity 17, and then heat the coated wire belt 12 and the first roller 11 and the second roller 13 in the cavity 17. When it is necessary to cool down the inside of the shell 1, the power supply of the linear guide 5 can be turned on, and the slider 16 can be controlled by the programmable control system so that the slider 16 can slide out from the inside of the shell 1 along the linear guide 5, so that the slide box 4 is separated from the shell 1. At this time, the heat in the slide box 4 will be in the external environment, and at the same time, a larger opening will appear at the bottom of the shell 1, which is conducive to the entry of low-temperature air from the outside, thereby causing the temperature inside the shell 1 to drop rapidly.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
