Description

Technical Field

[0001] The utility model belongs to the technical field of polishing machines, in particular to an environmentally friendly abrasive belt polishing machine. Background Art

[0002] In the field of welding material processing, polishing is an important process to improve the surface quality of welding materials and remove burrs and unevenness. Belt polishers are widely used in this field due to their high efficiency and flexible polishing effect. However, traditional belt polishers face a significant problem during use: the design of the angle adjustment mechanism is unreasonable.

[0003] Existing belt polishers are usually equipped with angle adjustment mechanisms to meet the polishing requirements of welds of different shapes and angles. However, these adjustment mechanisms often have design defects, that is, in order to facilitate angle adjustment and maintenance, the polishing structure (such as abrasive belts, pulleys, etc.) is exposed. This leakage not only causes dust and debris generated during the polishing process to be directly scattered into the working environment, causing environmental pollution, but also seriously endangers the health of operators and increases the risk of occupational diseases such as pneumoconiosis.

[0004] Specifically, the dust and metal debris generated during the polishing process contain a large number of harmful particles. Operators who are exposed to such an environment for a long time are prone to inhaling these particles, causing damage to the respiratory system. In addition, the accumulation of dust will affect the normal operation of the equipment, increase maintenance costs and downtime.

[0005] It can be seen that it is particularly important to design an environmentally friendly belt polisher that can cover the polishing structure, effectively collect dust, and facilitate angle adjustment. Summary of the invention

DETAILED DESCRIPTION

[0024] In order to better understand the present invention, Figures 1 to 4 The implementation modes of the present utility model will be explained in detail.

[0025] It should be noted that the directions "front, back, left, right, up, down" mentioned in the text are all based on Figure 1 The "front, back, left, right, up, down" directions in the utility model are used as the reference. The environmentally friendly abrasive belt polishing machine of the utility model comprises a base 1, which serves as a supporting platform for the entire device. The base 1 is provided with an articulated seat 2 for mounting an articulated shaft 3. The articulated shaft 3 is articulated with the bottom of the housing 4, so that the housing 4 can be adjusted in angle around the articulated shaft 3.

[0026] The housing 4 has an inner cavity 5, in which a first pulley 6 and a second pulley 7 are installed, and the two are connected by an abrasive belt 8 to form an abrasive belt 8 system required for polishing. Figure 2 As shown in the figure, the top of the housing 4 is provided with an opening slot 9 for the abrasive belt 8 to extend out, allowing the abrasive belt 8 to partially extend out by 0.5 cm to 1 cm so as to contact the workpiece to be polished. The lower end of the housing 4 is designed to extend inward to better seal the inner cavity 5, reduce dust leakage, and facilitate dust collection.

[0027] A dust drawer 10 is provided on one side of the housing 4, and the drawer is connected to the housing 4 via a first locking portion 11 (preferably a knob buckle) to facilitate extraction and cleaning of dust and debris generated during the polishing process.

[0028] A driving motor 12 is mounted on the base 1, and its driving shaft 13 is coaxially arranged with the hinge shaft 3 to ensure the stability of power transmission. The driving motor 12 is connected to the first pulley 6 through a transmission part to drive the abrasive belt 8 to rotate for polishing. Figure 3As shown in , the transmission part is a transmission belt 14 , and the driving shaft 13 of the driving motor 12 and the first pulley 6 are respectively provided with a transmission wheel 15 adapted to the transmission belt 14 .

[0029] In order to facilitate the adjustment of the angle of the housing 4, a slide plate 16 is provided on the base 1, and the slide plate 16 is connected to the housing 4 via a connecting rod 17. The two ends of the connecting rod 17 are respectively hinged to the slide plate 16 and the housing 4 to form a four-link 17 mechanism, so that the housing 4 can rotate smoothly around the hinge shaft 3.

[0030] like Figure 2 and Figure 4 As shown in the figure, a T-shaped slot 19 is provided on the base 1, and mutually symmetrical limiting racks 20 are arranged on both sides. The slide plate 16 is made of an elastic steel plate, and its outer end is bent upward and inward to form a pedal 21, and the inner end of the pedal 21 is provided with a latch 22 adapted to the limiting rack 20. By stepping on the pedal 21, the latch 22 is engaged with the limiting rack 20, so that the slide plate 16 is fixed, thereby locking the angle of the housing 4. At the same time, the pedal 21 is provided with an anti-slip pattern 24 to improve the safety of operation.

[0031] In order to avoid the pedal 21 being damaged by excessive stepping, Figure 2 As shown in FIG. 1 , a rubber limiting block 23 is also provided on the slide plate 16 to limit the pedal 21 .

[0032] To control the angle more precisely, Figure 4 As shown in FIG, the base 1 is provided with a scale 25 on one side of the T-slot 19 to facilitate the user to adjust according to needs.

[0033] like Figure 1 and Figure 3 As shown in the figure, a first baffle 26 is provided on one side of the housing 4, and a plurality of slots 27 are provided on the first baffle 26, and second baffles 29 of different heights can be inserted as needed to adjust the size or shape of the polishing area. In addition, the first baffle 26 is designed to slide laterally and is connected to the housing 4 through a second locking portion 28 (preferably a tightening bolt), which further enhances the flexibility and practicality of the device.

[0034] like Figure 2 The casing 4 shown in the figure is also provided with an inspection port, on which a side door 30 is hinged, and the side door 30 is connected to the casing 4 via a third locking portion 31 (preferably a knob buckle), which facilitates daily maintenance and inspection of the equipment.

[0035] The usage and principle of this utility model:

[0036] Preparation stage: First, according to the needs of the workpiece to be polished, consider whether to use the position of the first baffle 26 or the second baffle 29, and use the support and limit of the first baffle 26 or the second baffle 29 to assist the workpiece polishing. Then, by stepping on the pedal 21 and sliding the slide plate 16, the locking teeth 22 on the pedal 21 are engaged with the limit rack 20 on the base 1 to lock the initial angle of the housing 4.

[0037] Start polishing: Turn on the power supply, start the drive motor 12, and the motor drives the abrasive belt 8 to rotate through the transmission part. Place the workpiece to be polished under the abrasive belt 8, and make the abrasive belt 8 contact with the surface of the workpiece by adjusting the position of the workpiece or the angle of the housing 4 to perform the polishing operation.

[0038] Adjusting the angle: During the polishing process, if you need to adjust the polishing angle, you can loosen the locking mechanism, step on the pedal 21 and slide the slide 16, the housing 4 changes its angle to the desired position, and when you lift your foot, the latch 22 on the pedal 21 re-engages the limit rack 20 to lock the angle.

[0039] Cleaning and maintenance: After polishing is completed, turn off the power, open the dust drawer 10, and clean the collected dust and debris. Regularly check the wear of the sanding belt 8 and replace it in time to ensure the polishing quality. At the same time, the equipment can be maintained and repaired through the inspection port.
