Description

Technical Field

[0001] The utility model belongs to the field of shoe manufacturing, and particularly relates to a device for providing constant-temperature water for the edge of a shoe upper piece. Background Art

[0002] In the process of leather shoe manufacturing, according to the production specification requirements, the operation of slicing the edge of a component into a slope shape is called edge slicing, also known as "shoe upper slicing" or "leather slicing". For example, the normal thickness of the shoe upper material is 1.5 mm. After edge slicing, the edge of the shoe upper becomes a thin sheet with a slope. Refer to Figure 1 , and then place the thin sheet at the position with a seam on the shoe upper. In this way, after stitching, there will be no protruding ridge on the shoe upper, and it can avoid rubbing the foot inside the shoe.

[0003] When directly placing the shoe piece on the edge slicing machine for operation during edge slicing, there are two problems. One is that the shoe piece is relatively hard and not convenient for edge slicing; the other is that the edge slicing machine will generate a certain temperature during operation, and directly edge slicing will cause the shoe piece to adhere to the edge slicing machine. For this reason, a shoe piece treatment method - hot water soaking is proposed. Prepare a container filled with hot water, and place the shoe piece in the container for soaking. Since the hot water has a high temperature, it can make the shoe piece soft and convenient for edge slicing operation; moreover, after soaking in water, the shoe piece is relatively moist and will not adhere to the edge slicing machine.

[0004] However, the hot water in the container will become cold after a period of time, and it is necessary to frequently change the hot water, which is inconvenient for operation. Content of the Utility Model

[0005] To solve the above deficiencies in the prior art, the utility model aims to provide a device for providing constant-temperature water for the edge of a shoe upper piece, so as to achieve the purpose of keeping the water in the container at a constant temperature and eliminating the need to frequently change the hot water.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A device for providing constant-temperature water for the edge of a shoe upper piece includes a container filled with water, and also includes a leakage protection distribution box, a water temperature sensor, an electric heating rod, and a control switch for controlling the start / stop of the electric heating rod;

[0008] The control switch is electrically connected to the electric heating rod, and the electric heating rod is arranged at a position below the water surface in the container;

[0009] The water temperature sensor is fixedly arranged inside the container, and the output end of the water temperature sensor is connected to the input end of the PLC in the leakage protection distribution box;

[0010] The control switch is electrically connected to the leakage protection distribution box.

[0011] As a limitation to the utility model: the container is an open water tank.

[0012] Due to the adoption of the above technical solution, the beneficial effects achieved by the present utility model compared with the prior art are as follows:

[0013] The present utility model includes a container filled with water, a leakage protection distribution box, a water temperature sensor, an electric heating rod, and a control switch for controlling the start / stop of the electric heating rod. When the water temperature sensor senses that the water temperature reaches the use temperature, it transmits a signal to the PLC, and the leakage protection distribution box controls the control switch to close, and the electric heating rod will not continue to heat the water; when the water temperature sensor senses that the water temperature is insufficient, the leakage protection distribution box controls the control switch to open, and the electric heating rod works to heat the water. The present utility model can automatically control the start / stop of the electric heating rod so that the water in the container always maintains a certain temperature, and there is no need to frequently replace the hot water.

[0014] In summary, the present utility model can ensure a constant water temperature and there is no need to frequently replace the water in the container; the present utility model is applicable to the shoemaking industry and is used for soaking shoe pieces before edge trimming.

[0020] The following describes the preferred embodiments of the present utility model with reference to the drawings. It should be understood that the preferred embodiments described herein are only for explaining and illustrating the present utility model and do not constitute a limitation to the present utility model.

[0021] As shown in Figure 2 and 3 , this embodiment includes a container filled with water. In this embodiment, the container is an open water tank 1, which is convenient for putting shoe pieces into the water tank 1 for soaking and taking out the soaked shoe pieces. Figure 2 and 3 The water in

[0022] This embodiment further includes a leakage protection distribution box 2, a water temperature sensor 3, an electric heating rod 4, and a control switch 5 for controlling the start / stop of the electric heating rod 4.

[0023] The leakage protection distribution box 2, the water temperature sensor 3, the electric heating rod 4, and the control switch 5 all adopt existing technologies, and their structures, connection relationships, and working principles will not be elaborated in this embodiment.

[0024] The control switch 5 is electrically connected to the electric heating rod 4. The electric heating rod 4 is arranged at a position below the water surface in the water tank 1, and the electric heating rod 4 works to heat the water in the water tank 1.

[0025] The water temperature sensor 3 is fixedly arranged inside the container, and the output end of the water temperature sensor 3 is connected to the input end of the PLC in the leakage protection distribution box 2; the control switch 5 is electrically connected to the leakage protection distribution box 2.

[0026] The working principle is as follows: When the water temperature sensor 3 senses that the water temperature reaches the set temperature, it transmits a signal to the PLC, and the leakage protection distribution box 2 controls the control switch 5 to close, and the electric heating rod 4 stops heating the water. Then the shoe pieces can be put into the water tank 1 for soaking. The temperature setting range value in the actual application of this embodiment is 35°C - 40°C, which is determined according to the weather. For example, it is usually set to 35°C in summer and 40°C in winter, and can be adjusted within the range in other seasons.

[0027] When the water temperature sensor 3 senses that the water temperature is insufficient, the leakage protection distribution box 2 controls the control switch 5 to turn on, and the electric heating rod 4 works to heat the water. This embodiment can automatically control the start / stop of the electric heating rod 4 to ensure that the water in the container is kept at a constant temperature without the need to frequently replace hot water.
