Description

Technical Field

[0001] The utility model relates to the technical field of thermos cup production, in particular to a double-station automatic sanding machine for the mouth of a thermos cup. Background Art

[0002] The stainless steel thermos is made of double-layer stainless steel inside and outside. The inner liner and the outer shell are combined together by welding technology, and then the air in the interlayer between the inner liner and the outer shell is extracted by vacuum technology to achieve the effect of vacuum insulation. Therefore, the mouth of the thermos needs to be polished. Prior art, such as the CN213615682U utility model patent, discloses a polishing assembly, which drives the polishing part to swing through a driving mechanism. Before polishing, the swing angle of the polishing part can be set according to the structure of the mouth of the thermos, so that the polishing part can better contact with the mouth of the thermos, thereby improving the polishing effect. As can be seen from the above structure, there is a possibility of insufficient and discontinuous polishing in the prior art, which is not conducive to the realization of continuous and smooth polishing.

DETAILED DESCRIPTION

[0023] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0024] This embodiment discloses a double-station automatic sanding machine. Figures 1 to 5 As shown, it includes a mounting frame 1 and a grinding wheel 2, wherein the mounting frame 1 is provided with an automatic pressing and following device for pressing the stainless steel cup body 100 against the surface of the rotating grinding wheel 2; the automatic pressing and following device includes a distance adjusting component 3 for adjusting the relative distance between the stainless steel cup body 100 and the grinding wheel 2 and a pressing component 4 for pressing the stainless steel cup mouth against the surface of the grinding wheel 2 between two adjustment distances of the distance adjusting component 3.

[0025] The distance adjustment component 3 in this embodiment includes a driving motor 31 and a mounting plate 32 driven by the driving motor 31 to move up and down to change the distance relative to the side wall of the grinding wheel 2. In this embodiment, the stainless steel cup body 100 to be ground has its mouth facing the grinding wheel 2 in the vertical direction, wherein a clamping component 4 for pressing the mouth of the stainless steel cup body 100 against the surface of the grinding wheel 2 is arranged on the mounting plate 32, and the mounting plate 32 is displaced to adjust the distance under the drive of the driving motor 31; when the driving motor 31 drives the mounting plate 32 and the stainless steel cup body 100 to adjust the large distance, the clamping component 4 drives the stainless steel cup body 100 to press against the surface of the grinding wheel 2 for real-time fine-tuning.

[0026] The driving rod of the driving motor 31 in this embodiment drives the mounting plate 32 to move up and down through a slider 34 nested on the track 33. In this embodiment, the driving motor 31 cooperates with the movable structure of the track 33-slider 34 to effectively ensure that the displacement of the mounting plate 32 is reliable and stable.

[0027] The clamping assembly 4 in this embodiment includes a clamping drive mechanism 41 hinged between the mounting plate 32 and the grinding wheel 2, a connecting rod 46, a cup seat positioning mechanism 5 driven by the connecting rod 46 and used to support the stainless steel cup body, and a cup bottom clamping mechanism arranged opposite to the cup seat positioning mechanism 5.

[0028] In this embodiment, the clamping drive mechanism 41 comprises a rotating plate 42 hinged on the mounting plate 32, one end of the rotating plate 42 is hinged with a rolling bearing 43, and the rolling bearing 43 rolls along a fixed guide surface 44; a tension spring 45 is installed between the other end of the rotating plate 42 and the mounting plate 32 to rotate the rotating plate 42 toward the grinding wheel 2;

[0029] The tension spring 45 has a tendency to pull the rotating plate 42 to rotate toward the grinding wheel 2, and the rotating plate 42 drives the connecting rod 46, and the connecting rod 46 pushes the cup seat positioning mechanism 5 to rotate toward the grinding wheel 2. One end of the tension spring 45 is relatively fixedly hinged to the rotating plate 42 with the connecting rod 46, and the other end of the tension spring 45 is fixedly connected to the fixing pin 321 of the mounting plate 32; in this embodiment, the continuous tension provided by the tension spring 45 is used as a continuous driving force to press the cup body to be ground against the surface of the grinding wheel 2 through the pressing assembly 4.

[0030] In the process of adjusting the distance twice by the distance adjustment assembly 3 in this embodiment, the driving motor 31 drives the mounting plate 32 to move downward, and the rolling bearing 43 moves upward relative to the fixed guide surface 44, and the guide surface 44 through which the rolling bearing 43 passes has a structure that is inclined from bottom to top and toward the grinding wheel 2. In this embodiment, the cup mouth is further pressed against the surface of the grinding wheel 2 by the driving force of the tension spring 45 in cooperation with the guide surface 44 of the rolling bearing 43.

[0031] The cup seat positioning mechanism 5 in this embodiment includes a connecting plate 51 which is hinged at the lower part to the mounting plate 32 and is arranged parallel to the mounting plate 32. A positioning seat 52 for supporting and positioning the stainless steel cup body 100 is horizontally installed at the upper end of the connecting plate 51. The cup seat positioning mechanism 5 in this embodiment also includes a rotating downward pressing cylinder 53 for pressing the stainless steel cup body 100 against the positioning seat 52 and a clamp 54 driven by the rotating downward pressing cylinder 53. The clamp 54 and the positioning seat 52 clamp and fix the stainless steel cup body 100, and the pressing assembly 4 presses the cup body to be ground against the surface of the grinding wheel 2.

[0032] In this embodiment, the lower part of the grinding wheel 2 is placed in the housing 6, and the upper part of the grinding wheel 2 is also covered with a movable cover 7 that moves relative to the grinding wheel 2. The movable cover 7 is fixed to the mounting plate 32, and the movable cover 7 follows the mounting plate 32 to keep the same moving path as the distance adjustment component 3. In this embodiment, the movable cover 7 effectively ensures the enclosure of the grinding process and reduces the overflow of particles generated by the grinding.

[0033] The specific working process of this embodiment is as follows:

[0034] The stainless steel cup body 100 to be ground is clamped and positioned by the cup seat positioning mechanism 5, and the distance between the stainless steel cup body 100 and the grinding wheel 2 is adjusted by the driving motor 31. As the grinding wheel 2 rotates, the pressing component 4 presses the stainless steel cup mouth against the surface of the grinding wheel 2; as the grinding progresses, the size of the grinding wheel 2 decreases until the grinding effect decreases, and the relative distance between the stainless steel cup body 100 and the grinding wheel 2 is adjusted again by the distance adjustment component 3; thereafter, under the action of the pressing component 4, the stainless steel cup body 100 is kept in close contact with the grinding wheel 2 during the grinding process, so that the stainless steel cup body 100 is pressed against the surface of the rotating grinding wheel 2 and automatically follows the pressing;

[0035] This embodiment effectively maintains stable and close contact between the cup body to be ground and the grinding wheel 2, ensuring reliable grinding; especially when the inner diameter of the grinding wheel 2 is reduced during the grinding process, the cup mouth and the surface of the grinding wheel 2 can also be kept in stable contact.

[0036] The above embodiments and drawings do not limit the product form and style of the present embodiment. Any appropriate changes or modifications made thereto by a person of ordinary skill in the relevant technical field should be deemed to be within the patent scope of the present embodiment.
