Description

Technical Field

[0001] The present invention relates to the technical field related to heater processing, and in particular to a dishwasher heater detection device. Background Art

[0002] A dishwasher is a common kitchen appliance that uses an internal spray system to spray high-temperature, high-pressure water onto tableware to remove oil and stains from the surface of the tableware. U-shaped heating tubes are usually used inside the dishwasher to heat water or air. They can heat water during the washing process and heat air during the drying stage, enabling a heater to be used for multiple purposes in different working links, increasing the versatility and economy of the equipment. During the installation process, the U-shaped heater needs to be precisely coordinated with other components. For example, in some cases where the U-shaped heating tube needs to be installed in a specific fixture, bracket or equipment, if the tube spacing does not meet the requirements, it may cause installation difficulties or even impossible to install. For this reason, the tube spacing of the U-shaped heater needs to be tested.

[0003] At present, the existing U-shaped heating tube inspection usually uses the feeler gauge measurement method to measure the tube spacing. Usually, a thin piece of feeler gauge is inserted into the gap between the U-shaped tubes. The tube spacing is roughly determined by selecting a feeler gauge of appropriate thickness. In addition, the surface of the U-shaped tube is easily scratched during operation. Alternatively, a sample comparison method is used. However, the measurement accuracy of these inspection methods is greatly affected by human factors, and the measurement speed is slow, making them unsuitable for rapid inspection in mass production. Summary of the Invention

[0004] The purpose of the present invention is to provide a dishwasher heater detection device to solve the problems of the existing U-shaped heating tube detection method proposed in the above background technology, that its measurement accuracy is greatly affected by human factors, and its measurement speed is slow, which is not suitable for rapid detection in mass production.

[0005] To achieve the above object, the present invention provides the following technical solution: a dishwasher heater detection device, comprising a base,

[0006] A mounting plate is fixed on the top of the base, and two sets of support columns are provided above the side of the mounting plate, and U-shaped heating tubes are installed on the support columns. A cylinder is fixed on the top of the mounting plate, and a cylinder is provided at the output end of the cylinder. A fixing frame is provided below the cylinder, and pressure wheels are provided at both ends of the bottom of the fixing frame.

[0007] An L-shaped movable frame is provided below the side of the mounting plate, and two groups of detection tubes are provided on the side of the L-shaped movable frame close to the mounting plate, and several groups of touch units are provided on the inner walls of the detection tubes;

[0008] A slot 1 is vertically opened on the mounting plate, and a driving mechanism is provided in the slot 1, and the driving mechanism is used to drive the L-shaped movable frame to move vertically;

[0009] The L-shaped movable frame is provided with an adjustment mechanism 1, which is used to drive the detection tube to move horizontally. The mounting plate is provided with a second empty slot horizontally, and the second empty slot is provided with an adjustment mechanism 2, which is used to drive the support column to move horizontally.

[0010] In the above technical solution, the U-shaped heating tube is installed on two groups of support columns, and the cylinder is used to drive the cylinder and the fixed frame to descend, so that the pressure wheels at both ends of the bottom of the fixed frame press the top of the U-shaped heating tube, thereby fixing the U-shaped heating tube. After that, the L-shaped movable frame can be driven to rise by the driving mechanism, so that the L-shaped movable frame drives the two groups of detection tubes to move upward from the bottom of the U-shaped heating tube. Since multiple groups of touch units are provided on the inner wall of the detection tube, when the U-shaped heating tube is inserted, if the tube spacing deviates, the outer wall of the U-shaped heating tube can trigger the touch unit at the corresponding position, so that it can be intuitively judged whether the tube spacing is too large or too small, and there is no need for professional measurement personnel to perform complex data analysis and judgment. It can detect changes in tube spacing more accurately and better ensure product quality. In addition, this method is relatively simple to operate, shortens detection time, and improves production efficiency.

[0011] Preferably, an annular groove is provided on the support column, and the U-shaped heating tube is located in the annular groove.

[0012] In the above technical solution, the annular groove on the support column can limit and position the U-shaped heating tube to prevent the U-shaped heating tube from detaching from the support column.

[0013] Preferably, a spring is fixed inside the cylinder, and a movable rod is provided inside the cylinder, and both ends of the movable rod are connected to the fixing frame and the spring respectively.

[0014] In the above technical solution, a spring is arranged on the cylinder, and the arrangement of the spring enables the movable rod and the fixing frame to be extended and retracted, thereby preventing the fixing frame from causing damage and deformation to the U-shaped heating tube due to excessive downward pressure when pressing the U-shaped heating tube.

[0015] Preferably, the driving mechanism includes a screw rod 1, which is installed in an empty slot 1. A motor 1 is fixed to the bottom of the mounting plate, and the output end of the motor 1 is connected to the screw rod 1. A movable block is threadedly connected to the screw rod 1, and the movable block is fixedly connected to the L-shaped movable frame.

[0016] In the above technical solution, the motor drives the screw rod to rotate, which can drive the movable block threadedly connected to it to move vertically in the empty slot, so that the movable block drives the L-shaped movable frame and the detection tube to rise to detect the U-shaped heating tube.

[0017] Preferably, a controller and a warning light are respectively provided at both ends of the side portion of the mounting plate, and the controller is connected to the warning light and the touch unit respectively.

[0018] In the above technical solution, when detecting the spacing between the U-shaped heating tubes, after the outer wall of the U-shaped heating tube contacts the touch unit inside the detection tube, the touch unit will transmit an electrical signal to the controller. At the same time, the controller will turn on the prompt light and emit a prompt sound to remind the staff that the spacing between the U-shaped heating tubes has deviated, so that the staff can detect the U-shaped heating tubes more quickly.

[0019] Preferably, the adjustment mechanism 1 includes a screw rod 2, which is installed on the inner side of the L-shaped movable frame, and a mounting block is threadedly connected to the screw rod 2, and the mounting block is fixedly connected to the detection tube. A handwheel is provided on the side of the L-shaped movable frame, and the handwheel is connected to the screw rod 2.

[0020] In the above technical solution, by rotating the handwheel to drive the second screw to rotate, the second screw can drive the two sets of mounting blocks threadedly connected to it to move laterally, thereby adjusting the spacing between the two sets of mounting blocks and the detection tube. In this way, U-shaped heating tubes with different tube spacings can be detected, making it more widely used and suitable for production and detection operations of different types of U-shaped heating tubes.

[0021] Preferably, the second adjustment mechanism includes a third screw rod, which is installed in the second empty slot, and a placement block is threadedly connected to the third screw rod, and the placement block is fixedly connected to the support column. A second motor is provided on the side of the mounting plate, and the output end of the second motor is connected to the third screw rod.

[0022] In the above technical solution, the motor 2 drives the screw rod 3 to rotate, so that the screw rod 3 can drive the two groups of storage blocks threadedly connected to it to move horizontally in the empty slot 2, so as to adjust the distance between the two groups of storage blocks and the support columns. In this way, the two groups of support columns can support the inner ring of the U-shaped heating tube with different curvatures, and can meet the support requirements of U-shaped heating tubes of various specifications. When producing various models of U-shaped heating tubes or other related products, there is no need to frequently replace the supporting equipment, which reduces the production cost and the complexity of equipment management. In addition, this two-point support structure is relatively simple, which makes the overall design, manufacturing and maintenance easier, reduces the probability of equipment failure, and improves the stability and reliability of production.

[0023] Compared with the prior art, the beneficial effects of the present invention are: the dishwasher heater detection device,

[0024] (1) The L-shaped movable frame is driven to rise by a driving mechanism, so that the L-shaped movable frame drives two groups of detection tubes to move upward from the bottom of the U-shaped heating tube. Since multiple groups of touch units are provided on the inner wall of the detection tube, when the U-shaped heating tube is inserted, if there is a deviation in the tube spacing, the outer wall of the U-shaped heating tube can trigger the touch unit at the corresponding position. Compared with some traditional rough measurement methods, such as the comparison method or the use of measuring tools for rough measurement, the change of the tube spacing can be detected more accurately. For the production of U-shaped heating tubes with high precision requirements, the product quality can be better guaranteed. In addition, the operation of this method is relatively simple. It only needs to insert the U-shaped heating tube into the detection tube for detection. There is no need to perform complicated measurement operations and reading calculations, which reduces the detection time. Especially in the batch production of U-shaped heating tubes, a large number of products can be quickly detected, thereby improving production efficiency.

[0025] (2) The arc-shaped inner ring of the U-shaped heating tube is supported by two groups of support columns, and the spacing between the two groups of support columns is adjusted by setting an adjustment mechanism 2. It can be flexibly adjusted according to the actual shape of the U-shaped heating tube, so that U-shaped heating tubes with different tube spacings can be supported, and the spacing between the two groups of detection tubes is adjusted by adjusting mechanism 1, so that U-shaped heating tubes with different tube spacings can be detected, making the equipment highly versatile and able to meet the support and detection needs of U-shaped heating tubes of various specifications.
