Description

Technical Field

[0001] This utility model belongs to the field of electrical component manufacturing, specifically relating to a heat shrink tubing roller baking machine. Background Technology

[0002] Nowadays, the safety performance requirements for electrical components are becoming increasingly stringent, especially for various connectors and wire connections. Heat shrink tubing is used to cover the contact points between the connectors and wires, and the heat shrink tubing is heat-shrinked and dried to ensure that it tightly wraps between the metal conductor and the insulating jacket at the weld joint, thereby improving the insulation performance of electrical components and production efficiency.

[0003] Many existing methods for drying heat shrink tubing employ fan drying, such as CN 222329100 U, which describes a heat shrink tubing drying machine with a limiting mechanism. This machine includes a conveyor belt, an outer mounting frame, a drying assembly inside the mounting frame, and a tray on the upper surface of the conveyor belt. The tray contains a limiting assembly comprising a groove, a screw, a slide, a limiting plate, and an electric push rod, with a slider fixedly mounted on the right end of the electric push rod. However, this method involves mounting multiple trays on the conveyor belt, each with its own limiting assembly, resulting in a complex structure, limited drying capacity per tray, low production efficiency, and high equipment costs, thus increasing production costs for enterprises. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a heat shrink tubing roller baking machine with a simple structure, improved production efficiency, and reduced production costs.

[0005] The technical solution for the purpose of this utility model is: A heat shrink tubing roller baking machine includes a conveying device. The conveyor belt of the conveying device is made of stainless steel mesh belt. The conveying support of the conveying device has multiple support rollers evenly arranged along the conveying direction. Multiple first heating components are provided in the middle of the conveying support of the conveying device. The multiple first heating components are located at the lower end of the conveyor belt. A certain distance is left between the first heating components and the conveyor belt. A drying hood is provided at the upper end of the conveying support of the conveying device. A second heating component is provided on the inner side wall of the drying hood.

[0006] Furthermore, both the first heating component and the second heating component are electric heating tubes. The two ends of the first heating component are respectively mounted on the conveying bracket of the conveying device through the first support base, and the second heating component is mounted on the inner side wall of the drying hood through the second support base.

[0007] Furthermore, it also includes a fan, which is disposed at the upper end of the inner side of the drying hood.

[0008] Furthermore, it also includes a high-temperature resistant rubber sleeve, which is fitted onto the drive roller of the conveying device.

[0009] Furthermore, the drying hood has an inverted concave structure with openings on both sides, the second heating component is disposed on the left and right sides of the drying hood, the front and rear sides of the drying hood are open, and the two opening sides are also provided with a shielding curtain.

[0010] Furthermore, the drying hood is provided with an observation hole, and a transparent baffle is provided inside the observation hole.

[0011] Furthermore, the temperature sensor is used to monitor the temperature inside the drying hood.

[0012] The above technical solution has the following beneficial effects: This utility model has a simple and compact structure. The conveyor belt of the conveying device is made of stainless steel mesh belt. Multiple support rollers are set on the conveyor support to support the stainless steel mesh belt. Multiple first heating components and a drying hood are set in the middle of the conveyor support. The inner wall of the drying hood is equipped with a second heating component. The heat shrink tubing is heated by the first heating component and the second heating component to cause heat shrinkage. The conveyor belt can hold more products, which improves the efficiency of production and processing and reduces production costs.

[0013] Adding a fan can quickly dissipate heat and ensure that the heat shrink tubing is heated evenly.

[0014] It also includes a high-temperature resistant rubber sleeve, which is fitted onto the drive roller of the conveyor device. The high-temperature resistant rubber sleeve can increase the friction force with the conveyor belt, thereby ensuring that the drive roller and the driven roller drive the conveyor belt to rotate.

[0015] The drying hood has an inverted concave structure with openings on both sides. The second heating component is located on the left and right sides of the drying hood. The front and rear opening sides of the drying hood are also equipped with shielding curtains, which facilitate the replacement of the second heating component and also serve to keep the temperature warm.

[0016] The drying hood is provided with an observation hole, and a transparent baffle is provided inside the observation hole, so that the condition inside the drying hood can be easily observed through the observation hole.

[0017] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details. Attached Figure Description

The conveyor belt 2 is mounted on the drive roller 3 and the driven roller 4. The drive motor is connected to the drive roller via a transmission wheel and a transmission belt. The conveyor belt 2 of the conveying device is made of stainless steel mesh belt. The high-temperature resistant rubber sleeve 5 is fitted in the middle of the drive roller 3, increasing the friction between the drive roller 3 and the conveyor belt 2, so that the drive roller 3 can stably drive the conveyor belt 2 to rotate.

[0022] The conveying support 1 of the conveying device is provided with multiple first heating components 6 in the middle. In this specific embodiment, five first heating components 6 are arranged sequentially on the conveying support. The multiple first heating components are located at the lower end of the conveyor belt 2. A certain distance of 20-30cm is left between the first heating components 6 and the conveyor belt 2. The baking parameters set in this technical solution are within the range that the heat shrink tubing can withstand. Baking is a kind of heat shrinking of the heat shrink tubing and will not have any impact on the heat shrink tubing material.

[0023] The conveyor support 1 is evenly arranged with multiple support rollers 9 along the conveying direction. The support rollers 9 not only support the conveyor belt 2, but also prevent the first heating component 6 from directly contacting the heat shrink tubing to be dried, thereby ensuring quality.

How the heating switch controls the interaction between itself and the electric heating elements, and how the drive motor switch controls the drive motor, as well as the internal wiring, are all conventional existing technologies in the field and will not be elaborated upon here.

[0027] Possibly, it also includes a fan and a fan switch. The fan is located at the upper end of the inner side of the drying hood. In this specific embodiment, the fan is located at the top of the inner side of the drying hood. The fan plays a role in rapid heat diffusion, ensuring uniform heating of the heat shrink tubing. The fan start switch is located on the control panel. The fan and the fan switch are electrically connected and used to control the start and stop of the fan. The wiring and other aspects of the control between the fan switch and the fan are conventional existing technology in the field and will not be described in detail here.

[0028] It also includes a temperature sensor and a temperature controller. The temperature sensor is electrically connected to the temperature controller. The temperature sensor is located inside the drying hood and is used to monitor the temperature inside the drying hood and send it to the temperature controller. The temperature controller is electrically connected to the electric heating tube and is used to adjust the temperature emitted by the electric heating tube. The connection between the temperature controller, the temperature sensor, and the electric heating tube is conventional prior art in the field and will not be described in detail here.
