Description

Technical Field

[0001] This utility model relates to the field of PTC heater technology, and in particular to a PTC heater roller device. Background Technology

[0002] A PTC heater is an electric heater composed of a PTC ceramic heating element and an aluminum tube. PTC heaters have the advantages of low thermal resistance and high heat exchange efficiency, achieving automatic temperature control and energy saving. The PTC heater utilizes the constant-temperature heating characteristic of the PTC thermistor. When the PTC thermistor is energized, it heats up automatically, causing its resistance to enter the transition region, and the surface temperature remains constant. This temperature depends only on the Curie temperature of the PTC thermistor and the applied voltage, and is essentially independent of the ambient temperature. The PTC heater primarily relies on the PTC heating element for heating. During the manufacturing process of a PTC heater, a glue-coating device is used to apply glue to the surface of the PTC heating element.

[0003] Currently, most PTC heater gluing devices on the market tend to cause glue to adhere to the gluing roller when applying glue to the PTC heating element, thus affecting the gluing effect of the device. In addition, after applying glue, it is not convenient for operators to unload the glued PTC heating element, which causes inconvenience to the operators. Utility Model Content

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0034] Example 1: Refer to Figures 1-7 This is the first embodiment of the present invention, which provides a PTC heater gluing device. It addresses the common problem in most existing PTC heater gluing devices on the market: when applying glue to the PTC heating element, glue tends to adhere to the gluing roller, affecting the gluing effect. Furthermore, existing PTC heater gluing devices make it inconvenient for operators to unload the glued PTC heating element after gluing, causing inconvenience. The device includes a workbench 1, which comprises a first fixed plate 101 and a second fixed plate 102, the first fixed plate 101 and the second fixed plate 102 respectively... The conveying rollers 103 are rotatably mounted inside the first fixed plate 101 and the second fixed plate 102 via bearings, and a fixed frame 104 is installed on one side wall of the first fixed plate 101. A second rectangular plate 105 is provided on one side wall of the first fixed plate 101, and a glue-rolling roller 1051 is rotatably mounted on one side wall of the second rectangular plate 105. A drive motor is installed at one end of the glue-rolling roller 1051 and is fixedly connected to the rear side of the second rectangular plate 105, so that the operator can start the drive motor to drive the glue-rolling roller 1051 to rotate.

[0035] A glue spraying box 1041 is installed at the bottom of the fixing frame 104, and an external glue tube 1042 is installed at the top of the glue spraying box 1041. A rectangular hole 1021 is opened inside the second fixing plate 102, and a first sliding groove 1022 is opened on the side wall at both ends of the rectangular hole 1021. A first slider 1023 is arranged inside the first sliding groove 1022, and a first rectangular plate 1024 is installed on the side wall of the first slider 1023. A fixing sleeve rod 1026 is installed at the top of the rectangular hole 1021, and the first rectangular plate 1024 is fixedly connected to the bottom of the fixing sleeve rod 1026. The interior of the first rectangular plate 1024 is rotatably connected to the glue rolling roller 1051 through a bearing. A high-pressure spring body 1027 is installed at the top of the fixing sleeve rod 1026, and a connecting rod 1025 is installed at the bottom of the high-pressure spring body 1027. The bottom of the connecting rod 1025 is fixedly connected to the top of the first rectangular plate 1024.

[0036] A rubber sleeve 1052 is installed on the outer wall of the glue roller 1051. The side walls at both ends of the glue roller 1051 are provided with mounting grooves 1053, and an electric heating tube 1054 is installed inside the mounting groove 1053. A door panel body 1055 is hinged to one end of the mounting groove 1053.

[0037] The lifting adjustment mechanism 2 includes a first groove 201, which is formed on the side wall of the first fixed plate 101. An installation block 202 is provided inside the first groove 201, and the side wall of the installation block 202 is fixedly connected to the side wall of the second rectangular plate 105. The internal threaded connection of the installation block 202 passes through the T-shaped threaded rod 203 at the top of the first fixed plate 101.

[0038] The sidewalls at both ends of the first groove 201 are provided with second sliding grooves 204, and the second sliding grooves 204 are provided with second sliders 205. The sidewalls of the second sliders 205 are fixedly connected to the sidewalls of the mounting block 202.

[0039] The specific working principle is as follows: First, the design of the rubber sleeve 1052 facilitates the absorption of adhesive, resulting in better adhesive application by the gluing roller 1051. Simultaneously, the heating element 1054 is activated to heat the rubber sleeve 1052, preventing the adhesive absorbed by the sleeve from sticking together due to low temperature, which would affect the gluing effect of the roller 1051. Furthermore, when applying adhesive to PTC heating elements of different thicknesses, the T-shaped threaded rod 203 is rotated... Furthermore, the T-shaped threaded rod 203 is threadedly connected to the mounting block 202, causing the T-shaped threaded rod 203 to rotate and drive the mounting block 202 to rise and fall on the outer wall of the T-shaped threaded rod 203. The rise and fall of the mounting block 202 causes the second rectangular plate 105 and the glue roller 1051 to rise and fall simultaneously. At the same time, through the design of the first sliding groove 1022 and the first slider 1023, the height of the glue roller 1051 can be adjusted by rotating the conveying roller 103, so that it can perform glue rolling on PTC heating elements of different thicknesses.

[0040] Example 2: Refer to Figures 1-7This is the first embodiment of the present invention. This embodiment provides a PTC heater gluing device, which can solve the problem that most PTC heater gluing devices on the market currently have problems. When applying glue to PTC heating elements, the glue tends to stick to the gluing roller, thus affecting the gluing effect of the gluing device. At the same time, after applying glue, it is not convenient for operators to unload the glued PTC heating elements, which causes inconvenience to the operators. The automatic unloading mechanism 3 includes a mounting frame 301 and an electric lifting rod 306. The mounting frame 301 is fixedly installed on the top of the workbench 1. An inclined plate 302 is hinged inside the mounting frame 301, and a guide rail 303 is provided at the bottom end of the inclined plate 302. A guide block 304 is provided inside the guide rail 303, and a hinge seat 305 is installed at the bottom end of the guide block 304. An electric lifting rod 306 is installed on the top of the workbench 1, and the top end of the electric lifting rod 306 is hinged to the bottom end of the hinge seat 305.

[0041] The specific working principle is as follows: when it is necessary to automatically unload the PTC heating element after it has been glued, the mounting frame 301 is first hinged to the inclined plate 302, and the electric lifting rod 306 is hinged to the hinge seat 305. The electric lifting rod 306 is raised and lowered to drive the guide block 304 to slide inside the guide rail 303 and drive the inclined plate 302 to rotate inside the mounting frame 301, so as to facilitate the adjustment of the tilt angle of the inclined plate 302 to unload the PTC heating element after it has been glued.

[0042] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
