Description

Technical Field

[0001] This utility model relates to the field of thermometer manufacturing technology, specifically a device for removing burrs after injection molding of electronic thermometers. Background Technology

[0002] An electronic thermometer is a portable device that uses electronic sensors (such as thermistors or thermocouples) to measure temperature. It is commonly used in medical, home, and industrial fields. Compared with mercury thermometers, electronic thermometers are safer, more drop-resistant, and safer to use.

[0003] Chinese utility model patent CN109278223A, published on January 29, 2019, discloses a tooling for removing burrs from injection molded parts. The tooling includes a base plate, a motor, an anti-rotation block, a support column, a slide block, a scraper, a scraper slider, a scraper screw, a spring, a rotating wheel screw, a support base, a rotating wheel slider, an outer rotating wheel, an inner rotating wheel, and a support base. The motor is mounted on the base plate, the anti-rotation block is fixed to the motor output shaft, the support column is mounted on the base plate, the slide block is mounted on the base plate, the scraper slider is mounted in the middle groove of the slide block, the scraper and scraper screw are respectively connected to both ends of the scraper slider, the rotating wheel slider slides in the side groove of the slide block, the outer rotating wheel and rotating wheel screw are respectively mounted on the rotating wheel slider, and the inner rotating wheel is optionally mounted on the top of the support base via a bearing. This invention allows the product to be placed on an anti-rotation block and a support column, with the inner and outer rotating wheels slightly clamping the outer ring of the product, allowing the product to rotate evenly. Then, the motor rotates, causing the product to rotate, and the scraper cuts and chamfers the edges. It has the advantages of simple operation, wide applicability, and high production efficiency.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the existing deburring devices can only remove burrs from the outer surface of rotating bodies, which makes them unsuitable for removing burrs from non-rotating objects. Therefore, they are unsuitable for removing burrs from the surface of electronic thermometers, which are roughly elongated. Therefore, it is necessary to design a special device for removing burrs generated by the parting line of the thermometer. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing deburring devices can only remove burrs from the outer surface of rotating bodies, making them unsuitable for removing burrs from non-rotating objects. This also makes them unsuitable for removing burrs from the surface of roughly elongated electronic thermometers. Therefore, it is necessary to design a special device for removing burrs generated by the mold parting line of a thermometer, and to provide a deburring device for electronic thermometers after injection molding.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] This utility model discloses a device for removing burrs after injection molding of an electronic thermometer, comprising a fixed base for aligning a conveyor belt; a plurality of threaded shafts are symmetrically threaded and connected to the fixed base; a fixed cover is movably connected to the end of each threaded shaft; a plurality of tensioning wheels are rotatably connected to the fixed cover; a belt is sleeved on each tensioning wheel; a motor is fixedly connected to the upper end of each tensioning wheel; symmetrically spaced slots are provided on the fixed base; a slider is slidably inserted into each slot; a fastener is threaded and connected to each slider; a support plate is detachably connected to the slider; a first sleeve is detachably fixed to the support plate; a scraper is slotted on the first sleeve.

[0008] Furthermore, a roller is rotatably connected to the end of the support plate; the roller contacts the rough surface of the electronic thermometer.

[0009] Furthermore, the support plate is sleeved with a second sleeve; the second sleeve is fixedly connected to an elastic element; the other end of the elastic element is fixedly connected to an adjusting base; the adjusting base is slidably sleeved in the spacer groove.

[0010] This utility model provides a device for removing burrs from an electronic thermometer after injection molding, which has the following beneficial effects:

[0011] 1. This utility model uses a conveyor belt structure consisting of four sets of motors, tensioning wheels and belts to clamp and move an electronic thermometer. Then, by adjusting the position of the scraper on the first sleeve and then the position of the first sleeve on the support plate, the scraper can contact the burrs for cutting and removing them. Then, through the threaded connection between the threaded shaft and the fixed base, the distance between the two fixed covers can be changed by rotating the threaded shaft, thereby adapting to electronic thermometers of different sizes for burr removal.

[0012] 2. This utility model uses symmetrical rollers to clamp the two sides of the electronic thermometer, so that after the electronic thermometer is exposed to the outside by moving from the clamping of the two belts, it is clamped by the two rollers and moved at the same time. At the same time, a scraper removes the burrs on the parting line of the outer surface of the electronic thermometer. Then the electronic thermometer enters the clamping of the next two belts and moves again to detach from the fixed base. Attached Figure Description

[0021] Please see Figure 1-3 As shown, a device for removing burrs after injection molding of an electronic thermometer includes a fixed base 1 aligned with a conveyor belt; multiple threaded shafts 2 are symmetrically threaded and connected to the fixed base 1; a fixed cover 3 is movably connected to the end of each threaded shaft 2; multiple tensioning wheels 5 are rotatably connected to the fixed cover 3; belts 6 are sleeved on the tensioning wheels 5; a motor 4 is fixedly connected to the upper end of each tensioning wheel 5; symmetrically spaced slots 7 are provided on the fixed base 1; sliders 8 are slidably inserted into the slots 7; fasteners 9 are threaded and connected to the sliders 8; a support plate 10 is detachably connected to the sliders 8; a first set of... Tube 11; A scraper 13 is slotted on the first sleeve 11. The electronic thermometer can be clamped and moved by a conveyor belt structure consisting of four sets of motors 4, tensioning wheels 5 and belts 6. The position of the scraper 13 on the first sleeve 11 and the position of the first sleeve 11 on the support plate 10 are adjusted so that the scraper 13 can contact the burrs for cutting. The screw shaft 2 is threaded to the fixed base 1, so that the distance between the two fixed covers 3 can be changed by rotating the screw shaft 2, thereby adapting to electronic thermometers of different sizes for burr removal.

[0022] Rollers 12 are rotatably connected to the end of the support plate 10. The rollers 12 contact the rough edge of the electronic thermometer. The two sides of the electronic thermometer are clamped by the symmetrical rollers 12, so that after the electronic thermometer is exposed to a certain distance from being clamped by the two belts 6, it is clamped by the two rollers 12 and moved. At the same time, the rough edge of the mold line on the outer surface of the electronic thermometer is scraped off by the scraper 13. Then the electronic thermometer is clamped by the next two belts 6 and moved again to detach from the fixed base 1.

[0023] The support plate 10 is fitted with a second sleeve 14; the second sleeve 14 is fixedly connected to an elastic element 15; the other end of the elastic element 15 is fixedly connected to an adjusting base 16; the adjusting base 16 is slidably fitted in the spacer groove 7. By adjusting the position of the adjusting base 16 in the spacer groove 7, the position of the second sleeve 14 on the support plate 10 is adjusted, thereby changing the degree of compression of the elastic element 15, so as to adapt to the pressure required for different thicknesses of burrs, thus making the removal more neat.

[0024] The lower end face of the fixed cover 3 slides in contact with the inner surface of the fixed base 1. This sliding contact allows the fixed cover 3 to be easily adjusted left and right to accommodate electronic thermometers of different widths.

[0025] A guide shaft 17 is fixedly connected to the fixed cover 3 in parallel with the threaded shaft 2. The guide shaft 17 ensures that the fixed cover 3 is always parallel to the side plate of the fixed base 1, so that the electronic thermometer is always clamped in parallel during the translation process.

[0026] The roller 12 is made of rubber; the scraper 13 has a threaded hole with a bolt connected to it. By rotating the bolt, the friction between the scraper 13 and the support plate 10 can be changed, so that it can be adapted to remove burrs from the sides of electronic thermometers of different widths.
