[0030] See also Figure 1 and Figure 3 In one embodiment, in order to make the use of the trimming mechanism 5 more reliable, in this embodiment, preferably, the trimming mechanism 5 includes a limit support plate 51, one end of the lower surface of the limit support plate 51 is fixedly connected with a limit slider 52 threadedly connected to the limit screw rod 6, the limit slider 52 is slidably connected to the support base 2, a dust removal box 593 is arranged above the limit support plate 51, and a plurality of second height adjustment members 50 for adjusting the height of the dust removal box 593 are arranged on the upper surface of the limit support plate 51. The second height adjustment member 50 is a hydraulic cylinder, and the dust removal box 593 One end close to the fixing mechanism 3 is rotatably connected to the limiting transmission tube 54, and the end of the limiting transmission tube 54 away from the dust removal box 593 is fixedly connected to the dust removal cover 57, and the end of the dust removal cover 57 away from the limiting transmission tube 54 is provided with a grinding disc 55, and the end of the limiting transmission tube 54 close to the dust removal box 593 is fixedly connected to the driven gear 590, and the end of the dust removal box 593 close to the dust removal cover 57 is fixedly connected to the second driver 591, the second driver 591 is a motor, and the output end of the second driver 591 is fixedly connected to the driving gear 53 meshing with the driven gear 590.

[0031] See also Figure 3 and Figure 4In one embodiment, in order to make the trimming mechanism 5 more functional, in this embodiment, preferably, the dust removal box 593 is fixedly connected to one end of the dust removal cover 57 close to the dust removal cover 57 with a protective cover 58 rotatably connected to the limit transmission pipe 54. The setting of the protective cover 58 prevents the driving gear 53 and the driven gear 590 from causing harm to the staff. The interior of the dust removal box 593 is fixedly connected to a negative pressure fan 592 corresponding to the limit transmission pipe 54. When in use, the air in the limit transmission pipe 54 is pumped to the interior of the dust removal box 593 through the negative pressure fan 592 to remove dust. A dust bag 595 is provided at one end of the box 593 away from the dust cover 57, and an exhaust hole 596 corresponding to the dust bag 595 is opened on the dust box 593. A plurality of dust holes 56 are opened at one end of the dust cover 57 away from the limiting transmission tube 54. The plurality of dust holes 56 are arranged in a circular array at the end of the dust cover 57. An anti-clogging filter 594 is provided inside the dust box 593. The anti-clogging filter 594 is made of a stainless steel mesh plate, and the mesh holes thereon are used for air to pass through. When the mesh plate blocks the air, the dust can be preliminarily blocked.

[0032] When in use, the dust hood 57 is put on the trimming end of the inner tank, so that the grinding disc 55 is against the workpiece, and then the dust hood 57 is driven to rotate by the second driver 591. At this time, the dust hood 57 drives the grinding disc 55 to rotate, so that the workpiece is polished by the grinding disc 55. The dust hood 57 gathers the dust generated by grinding to prevent the dust from floating around.

[0033] During the grinding process, the power of the negative pressure fan 592 is turned on. At this time, the external air enters the limit transmission tube 54 through the dust removal hole 56, and the grinding end of the workpiece is cooled down by the flow of air. In this process, the dust generated by grinding is driven into the limit transmission tube 54 by the flow of air, and then the dust follows the air into the dust removal box 593. At this time, the air is filtered and dust-removed by the anti-clogging filter element 594, and the dust-removed air is discharged after secondary dust removal by the dust removal bag 595.

[0034] The anti-clogging filter element 594 adopts a multi-step stepped shape design. Through this design, not only can the anti-clogging filter element 594 filter and remove dust from the air multiple times, but it can also effectively prevent the anti-clogging filter element 594 from being blocked during use and affecting the normal use of the user's dressing device. For example, when the leftmost filter step is blocked, the second and third filter steps can still be used normally. When the second filter step is also blocked, the third filter step can still be used normally, thereby forming a safety structure to ensure that the user can use the device normally. The multiple bottom bends and depressions of the anti-clogging filter element 594 can be used to collect filtered dust to prevent excessive dust from accumulating in the filtering part of the anti-clogging filter element 594 and affecting the normal operation of the anti-clogging filter element 594.

The output end of the second driver 591 is fixedly connected to a driving gear 53 meshing with the driven gear 590. A nylon filter is provided at one end of the dust box 593 away from the dust cover 57. An exhaust through hole 596 corresponding to the nylon filter is provided on the dust box 593. A negative pressure fan 592 corresponding to the limit transmission pipe 54 is fixedly connected inside the dust box 593. A plurality of dust removal through holes 56 are provided at one end of the dust cover 57 away from the limit transmission pipe 54. The plurality of dust removal through holes 56 are arranged in a circular array at the end of the dust cover 57. An anti-clogging filter 594 is provided inside the dust box 593, and the anti-clogging filter 594 is made of a plastic mesh.

[0036] See also Figure 1 In one embodiment, in order to make the device better fix the workpiece, in this embodiment, preferably, a first elastic reinforcement plate 4 for cooperating with the fixing mechanism 3 to reinforce the workpiece is provided at one end of the upper surface of the support base 2. The first elastic reinforcement plate 4 is a rubber plate. When in use, the workpiece is fixed by the first elastic reinforcement plate 4 to prevent slipping. Ground wheels 1 are provided at both ends of the lower surface of the support base 2. The setting of the ground wheels 1 makes it easy for the user to move the trimming device, making the use of the trimming device more user-friendly.

[0037] In another embodiment, a first elastic reinforcement plate 4 for cooperating with the fixing mechanism 3 to reinforce the workpiece is provided at one end of the upper surface of the support base 2. The first elastic reinforcement plate 4 is a silicone plate. When in use, the workpiece is fixed to prevent slipping by the first elastic reinforcement plate 4. Ground wheels 1 are provided at both ends of the lower surface of the support base 2. The setting of the ground wheels 1 facilitates the user to move the trimming device, making the use of the trimming device more user-friendly.

[0038] The working principle and use process of the present invention are as follows: when in use, the inner liner to be trimmed is placed on the first elastic reinforcement plate 4 at the end of the support base 2, and then the workpiece is reliably clamped and fixed by cooperating with the support base 2 through the fixing mechanism 3, and then the dust cover 57 is adjusted through the second height adjustment member 50 so that the dust cover 57 can cover the grinding end of the workpiece, and then the limiting screw 6 is driven to rotate by the first driver 7, and the position of the dust cover 57 is adjusted through the mutual cooperation of the limiting screw 6 and the limiting slider 52, so that the grinding disc 55 is against the grinding end of the workpiece.

[0039] Then, the second driver 591 drives the limit transmission tube 54 and the dust removal cover 57 to rotate. At this time, the dust removal cover 57 drives the grinding disc 55 to rotate, so that the workpiece is polished by the grinding disc 55. The protective cover 58 gathers the dust generated by grinding to prevent the dust from floating around. At the same time, the power of the negative pressure fan 592 is turned on. At this time, the external air enters the limit transmission tube 54 through the dust removal hole 56, and the grinding end of the workpiece is cooled by the flow of air. In this process, the dust generated by grinding is driven into the limit transmission tube 54 by the flow of air, and then the dust follows the air into the interior of the dust removal box 593. At this time, the air is filtered and dust-removed by the anti-clogging filter element 594, and the dust-removed air is discharged after secondary dust removal by the dust removal bag 595, thereby realizing multi-stage dust removal of the air.

[0040] Therefore, the end of the inner liner can be automatically polished through the mutual cooperation of multiple structures, so that the polishing flatness of the trimming device is better. Secondly, the device can remove dust during the polishing process to avoid a large amount of dust from being dispersed during the polishing process, and prevent the dust from being scattered everywhere and causing harm to the health of the workers. In addition, the device can cool the polishing part of the inner liner during use, so that the functions of the trimming device are richer. The present invention has a simple structure and is easy to use, and is worthy of promotion and use.
