Description

Technical Field

[0001] This utility model relates to the field of abrasive wheel packaging technology, specifically to an abrasive wheel packaging sealing device. Background Technology

[0002] Abrasive wheel packaging and sealing equipment is a device used for automated sealing and packaging of abrasive wheels (blades, discs). Through processes such as heat shrink wrapping and thermoforming, it achieves sealed protection of the abrasive wheels, preventing them from being bumped, damp, or contaminated by dust during transportation and storage, while also improving the neatness and aesthetics of the product packaging.

[0003] Existing abrasive wheel packaging and sealing devices typically consist of three core modules: conveying and positioning, film processing, and thermoforming, along with an electrical control system. The conveying and positioning module usually uses a conveyor belt, driven by a servo motor to achieve precise positioning and conveying of abrasive wheels of different diameters. The film processing module includes a dual-film roller rotating frame and an integrated sealing and cutting mechanism. The dual film rollers achieve differential rotation through a planetary gear set to adapt to different specifications of abrasive wheels. The heat-sealing blade and the cutting blade of the sealing and cutting mechanism operate synchronously through a cam linkage mechanism, combined with a negative pressure air passage to complete the sealing and cutting of the film. The thermoforming module adopts a ring-shaped heating chamber design. When the abrasive wheel wrapped in heat-shrink film moves into the heating chamber via the conveyor belt, the bottom of the heat-shrink film may come into contact with the surface of the conveyor belt, which may cause uneven heating of the bottom of the heat-shrink film, thus affecting the quality of the sealing of the bottom of the abrasive wheel. Utility Model Content

[0004] The technical problem to be solved by this utility model is that, in the use of existing grinding wheel packaging and sealing devices, the bottom end of the heat shrink film may be heated unevenly due to contact between the bottom end of the heat shrink film and the surface of the conveyor belt, thereby affecting the quality of the plastic sealing of the bottom end of the grinding wheel.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A grinding wheel packaging and sealing device includes a frame, a blower fixedly connected to the top of the frame for air circulation, an air inlet hood inserted into the inner top of the frame, a second pipe inserted into the top of the air inlet hood, an air outlet hood installed at the inner bottom of the frame, a first pipe inserted into the bottom of the air outlet hood for connecting to the air outlet at the top of the blower, a conveying assembly set in the middle of the frame, the conveying assembly including a roller rotatably connected to the inner side wall of the frame, a conveyor belt wound around the outer surface of the roller, a plurality of first through grooves opened on the surface of the conveyor belt, a second heating assembly installed in the middle of the frame, the second heating assembly including a mounting bracket fixedly connected to the inner side wall of the frame, a heating tube inserted into the middle of the mounting bracket, and two sets of heating plates installed on the inner side wall of the frame.

[0006] The beneficial effects of this utility model are: the bottom of the grinding wheel can be heated by the heating tube in conjunction with the conveyor belt and the first through groove; the blower can generate air force to blow the heat shrink film at the bottom of the grinding wheel through the air outlet hood, thereby improving the uniformity of heating; and the air inlet hood and the second pipe can be used to circulate the warm air and reduce heat loss, thereby improving the quality and efficiency of the grinding wheel packaging and sealing.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the mounting frame extends through the conveyor belt, and the heating tubes are distributed in an S-shape, with the heating tubes located between the air inlet hood and the air outlet hood.

[0009] Furthermore, the air intake hood is connected to the second pipe, the air outlet hood is connected to the first pipe, and a protective cover is snapped onto the bottom of the air intake hood. Several second through slots are opened on the surface of the protective cover.

[0010] Furthermore, a filter is inserted at the other end of the second pipe, and the other end of the filter is connected to the air inlet on the side wall of the blower. A removable filter element is installed in the middle of the filter.

[0011] Furthermore, the conveying assembly also includes a servo motor fixedly connected to the side wall of the frame, with the output end of the servo motor fixedly connected to the end of the roller.

[0012] Furthermore, displacement sensors are fixedly connected to the inner wall of the frame, and the displacement sensors are coupled to the blower, servo motor and heating tube respectively.

[0013] Furthermore, several temperature sensors are fixedly connected to the inner top of the frame, and the temperature sensors are coupled to the heating plate and the heating tube respectively.

[0014] Furthermore, curtains are installed at both ends of the frame, and the curtains are symmetrically distributed to close the two ends of the frame.

[0015] The beneficial effect of adopting the above-mentioned further solution is that by setting up a protective cover, a second channel and a filter, the protective cover and the second channel are used to filter large dust particles, and the filter is used to filter dust, thereby improving the stability of the warm airflow circulation.

[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

In the description of this application, "a plurality of" means two or more, unless otherwise precisely specified.

[0025] like Figure 1-5As shown, the grinding wheel packaging and sealing device includes a frame 1. The outer surface of the frame 1 is made of aluminum alloy and has a cavity in the middle. An insulation layer is installed on the inner wall of the cavity to reduce heat loss. A blower 2 is fixedly connected to the top of the frame 1 for air circulation. An air inlet hood 5 is inserted into the inner top of the frame 1 to expand the air intake range. A second pipe 6 is inserted into the top of the air inlet hood 5, and the air inlet hood 5 and the second pipe 6 are connected. An air outlet hood 7 is installed in the inner bottom of the frame 1. A first pipe 3 is inserted into the bottom of the air outlet hood 7 to connect to the air outlet at the top of the blower 2. The air outlet hood 7 and the first pipe 3 are connected to each other to blow air evenly. The middle of the frame 1... A conveying assembly 4 is provided, which includes a roller 401 rotatably connected to the inner wall of the frame 1. A conveyor belt 402 is wound around the outer surface of the roller 401. Several first through slots 403 are formed on the surface of the conveyor belt 402, allowing for heat radiation and air circulation. The conveying assembly 4 also includes a servo motor 404 bolted to the side wall of the frame 1. The output end of the servo motor 404 is fixedly connected to the end of the roller 401. Starting the servo motor 404 drives the roller 401 and the conveyor belt 402 to rotate, thereby improving the grinding wheel conveying efficiency. Two sets of heating elements are installed on the inner wall of the frame 1. Two sets of heating plates 8 are symmetrically distributed on both sides of the conveyor belt 402 to heat the cavity. The heating plates 8 are key components of the thermoforming module. The heating plates 8 have built-in heating wires that generate heat when energized, and the heat is transferred to the heat-shrinkable film on the surface of the grinding wheel through heat conduction. A second heating component 9 is installed in the middle of the frame 1. The second heating component 9 includes a mounting bracket 901 fixedly connected to the inner wall of the frame 1. A heating tube 902 is inserted in the middle of the mounting bracket 901. The heating tube 902 is the heating element of the thermoforming module. The heating tube 902 uses the principle of infrared radiation, converting electrical energy into heat energy and releasing infrared rays. The mounting bracket 901 passes through the conveyor belt 402. The heating tubes 902 are arranged in an S-shape to increase the heating area and facilitate air circulation. The heating tubes 902 are located between the air inlet hood 5 and the air outlet hood 7 to improve the stability of airflow circulation. When the bagged grinding wheel is transported to the middle of the frame 1 by the conveyor belt 402, the operator turns on the power to the heating plate 8 and the heating tubes 902 to heat the cavity and the bottom of the grinding wheel. Then, by starting the blower 2, air force can be generated to blow the heat shrink film at the bottom of the grinding wheel through the air outlet hood 7 to improve the uniformity of heating. Then, through the cooperation of the air inlet hood 5 and the second pipe 6, the warm airflow circulates to reduce heat loss, thereby improving the quality and efficiency of the grinding wheel packaging and sealing.

[0026] like Figure 1-5As shown, a filter 15 is inserted into the other end of the second pipe 6. The other end of the filter 15 is connected to the air inlet on the side wall of the blower 2. A removable filter element is installed in the middle of the filter 15. A protective cover 13 is snapped into the bottom of the air inlet cover 5. Several second through slots 14 are opened on the surface of the protective cover 13. The protective cover 13 and the second through slots 14 are used to filter large dust particles, and the filter 15 is used to filter dust, thereby improving the stability of the warm air circulation.

[0027] like Figure 3 As shown, a displacement sensor 12 is fixedly connected to the inner wall of the frame 1. The displacement sensor 12 is coupled to the blower 2, the servo motor 404 and the heating tube 902 respectively. The displacement sensor 12 is an important component of the conveying and positioning module and is used to monitor the position of the grinding wheel. The displacement sensor 12 converts the distance change between the grinding wheel and the reference position into an electrical signal through laser or infrared ranging and transmits it to the control system. Several temperature sensors 11 are fixedly connected to the inner top of the frame 1. The temperature sensors 11 are coupled to the heating plate 8 and the heating tube 902 respectively. The sensitive element of the temperature sensor 11 changes the resistance or electromotive force with the change of ambient temperature. After being amplified and filtered by the signal conditioning circuit, it is transmitted to the central control unit. The control unit adjusts the power of the infrared heating tube in real time by comparing the measured value with the set value to form a closed-loop control and ensure the temperature inside the thermoplastic cavity is stable.

[0028] like Figure 1-3 As shown, curtains 10 are installed at both ends of the frame 1, and the curtains 10 are symmetrically distributed to close the two ends of the frame 1.

[0029] Working principle: When using this abrasive wheel packaging and sealing device, first connect an external power supply, then move the abrasive wheel covered with heat-shrink film to the surface of the conveyor belt 402. Start the servo motor 404 to drive the conveyor belt 402 to rotate and move the abrasive wheel. When the displacement sensor 12 detects the position of the abrasive wheel, start the heating plate 8 to heat the inside of the frame 1, then start the heating tube 902 to heat the bottom of the abrasive wheel. Then start the blower 2 to generate airflow through the first pipe 3 and the air outlet 7 to blow the bottom of the abrasive wheel, thereby improving the uniformity of heating the bottom of the abrasive wheel. Then, the air intake hood 5 and the second pipe 6 work together to draw in air, thereby facilitating the circulation of warm air inside the frame 1, thereby improving the uniformity and efficiency of abrasive wheel heating, improving the stability of heat-shrink film shrinkage on the surface of the abrasive wheel, and improving the packaging quality of the abrasive wheel.

[0030] Secondly, the combination of the grinding wheel guard 13 and the filter 15 filters impurities in the circulating airflow, improving the stability of airflow.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
