[0002] A head refers to a component used to seal the end of a container to isolate the internal and external media, also known as an end cover. The heads of cylindrical containers are generally rotating shells. According to the shape of the head surface, it can be divided into convex, conical, flat and combined shapes. A convex head refers to a head with a convex outer surface shape, such as a hemispherical, elliptical, butterfly-shaped and spherical head without folded edges. In the prior art, a Chinese invention patent with publication number CN104625925B discloses an automatic polishing machine for polishing the surface of a head. The invention includes a polishing belt, which is arranged on a driven wheel and a driving wheel driven by an electric motor. The motor is fixedly mounted on a support frame, and the side of the support frame is mounted on the front of the positioning plate and the back of the positioning plate is connected to the lower end of the rocker arm. This invention uses the arrangement of multiple cylinders and pins to adjust the angle of the polishing belt within a wide range, and the adjustment cylinder can timely adjust the tension of the polishing belt, which is conducive to adapting to the polishing of the head surface under different conditions; the entire polishing process does not require manpower to be applied to the polishing machine, so that the polishing machine can continue to work before a polishing belt is scrapped.

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Reference Figures 1-15 As shown, the present invention provides an elliptical head polishing device, comprising a polishing mechanism 1, a moving mechanism 2, a mounting platform 3 and a head fixing mechanism 4, wherein the moving mechanism 2 is arranged on the mounting platform 3, the polishing mechanism 1 is installed on the moving mechanism 2, the moving mechanism 2 drives the polishing mechanism 1 to move on the mounting platform 3, and the head fixing mechanism 4 is arranged on the mounting platform 3. The head is fixed by the head fixing mechanism 4 and drives the head to rotate on the mounting platform 3, thereby ensuring that the polishing mechanism 1 can polish the head evenly, and the polishing mechanism 1 is above the head fixing mechanism 4;

[0036] like Figure 4 As shown, embodiment 1 of the polishing mechanism 1: the polishing mechanism 1 includes a polishing mounting frame 11, an upper mounting roller 12, a lower mounting roller 13, a main power roller 14, a polishing belt 15 and a polishing motor 16, the polishing mounting frame 11 is arranged in an L shape, and the polishing mounting frame 11 includes a horizontally arranged horizontal frame and a vertically arranged vertical frame, the polishing mounting frame 11 is arranged on the moving mechanism 2, the upper mounting roller 12 and the lower mounting roller 13 are rotatably mounted at both ends of the polishing mounting frame 11, and the main power roller 14 is arranged at the bottom of the polishing mounting frame 11. The polishing motor 16 is fixedly mounted on the polishing mounting frame 11, and the output end of the polishing motor 16 is connected to the main power roller 14. The polishing belt 15 is sleeved on the upper mounting roller 12, the lower mounting roller 13 and the main power roller 14. The main power roller 14 is driven to rotate by the polishing motor 16, and the polishing belt 15 is driven to rotate on the upper mounting roller 12 and the lower mounting roller 13 by the main power roller 14, and the outer surface of the head is polished by the polishing belt 15.

[0037] In some embodiments, a first roller frame 121 is provided between the upper mounting roller 12 and the polishing mounting frame 11, and a second roller frame 131 is provided between the lower mounting roller 13 and the polishing mounting frame 11. The first roller frame 121 and the second roller frame 131 have the same structure. The upper mounting roller 12 is rotatably provided on the first roller frame 121, and the lower mounting roller 13 is rotatably provided on the second roller frame 131. The first roller frame 121 and the second roller frame 131 are respectively provided with a frame limiting rod 122. The frame limiting rods 122 on the first roller frame 121 and the second roller frame 131 are respectively slidably inserted into the polishing mounting frame 11. The frame limiting rod 122 limits the vertical movement of the upper mounting roller 12, and the frame limiting rod 122 on the second roller frame 131 limits the horizontal movement of the lower mounting roller 13. The frame limiting rods 122 on the first roller frame 121 and the second roller frame 131 are respectively provided with contact springs 123. The upper mounting roller 12 and the lower mounting roller 13 are pushed toward the head fixing mechanism 4 by the contact springs 123 provided on the first roller frame 121 and the second roller frame 131, so as to ensure that the polishing belt 15 sleeved on the upper mounting roller 12 and the lower mounting roller 13 can fit tightly with the outer wall of the head, thereby improving the polishing efficiency and uniformity of the equipment on the head.

[0038] like Figure 5 As shown, the second embodiment of the polishing mechanism 1, the difference between the second embodiment of the polishing structure and the first embodiment is that an intermediate roller 17, an intermediate sliding frame 18 and an intermediate spring 19 are further provided, the polishing mounting frame 11 is provided with an intermediate slide groove, the intermediate sliding frame 18 is provided with an intermediate sliding protrusion 181, the intermediate sliding protrusion 181 is embedded in the intermediate slide groove, the intermediate sliding frame 18 slides along the direction of the intermediate slide groove, the intermediate roller 17 is rotatably set on the intermediate sliding frame 18, the intermediate spring 19 The intermediate spring 19 pushes the intermediate roller 17 to the head fixing mechanism 4, and the intermediate roller 17 is located between the upper mounting roller 12 and the lower mounting roller 13. The polishing belt 15 is wound around the intermediate roller 17. By arranging the intermediate roller 17 between the upper mounting roller 12 and the lower mounting roller 13, the polishing belt 15 can be further wound around, so that the polishing belt 15 between the upper mounting roller 12 and the lower mounting roller 13 can have a bent area. Figure 4 and attached Figure 5It can be seen that when the polishing belt 15 between the upper mounting roller 12 and the lower mounting roller 13 is in a straight state, when the head is polished in this state, the polishing belt 15 in the straight state needs to bend and fit with the outer wall of the head. At this time, due to the tension of the polishing belt 15, a greater pressure is generated on the curved part of the head, and the pressure generated on the outer side of the polishing belt 15 near the curved part of the head is smaller, resulting in uneven pressure generated by the polishing belt 15 on the head during polishing, which affects the polishing effect of the head. When the middle roller 17 is set, the upper mounting roller 12 is placed on the lower mounting roller 13. The polishing belt 15 between the upper roller 12 and the lower mounting roller 13 is divided into two straight lines, and the two straight lines on the polishing belt 15 exert the same pressing force on the outer wall of the head. This can ensure that the pressure of each area of the outer wall of the head is the same when the polishing belt 15 polishes the outer wall of the head, thereby improving the polishing uniformity of the polishing mechanism 1. This can ensure that the polishing belt 15 fits the curved head better, and prevent the difference in polishing degree caused by the different pressures of the polishing belt 15 on the distorted part of the head, which affects the polishing effect of the polishing belt 15 on the head.

[0039] On this basis, the intermediate roller 17 in this solution can adopt a flexible structure, such as rubber material. In this case, the polishing belt 15 sleeved on the intermediate roller 17 can further fit the outer surface of the head, thereby improving the polishing effect of the polishing belt 15 on the head;

[0040] It can be selected that the elastic coefficients of the intermediate spring 19 and the contact spring 123 in this solution are the same, so as to ensure that the intermediate roller 17, the upper mounting roller 12 and the lower mounting roller 13 can generate the same pressure, thereby ensuring that the polishing belt 15 can apply uniform pressure to the head.

[0041] like Figure 6 As shown, the third embodiment of the polishing mechanism 1 is different from the second embodiment in that multiple groups of intermediate rollers 17, intermediate sliding frames 18 and intermediate springs 19 are provided, and the polishing belt 15 is sequentially arranged through multiple intermediate rollers 17. By providing multiple groups of intermediate rollers 17, the polishing belt 15 between the upper mounting roller 12 and the lower mounting roller 13 can be bent into multiple sections, thereby further improving the fit between the polishing belt 15 and the head, and improving the uniformity of the polishing of the head by the polishing belt 15.

[0042] In some embodiments, the polishing mechanism 1 further includes a synchronization component 5, which includes a first synchronization wheel 51, a second synchronization wheel 52, a synchronization tensioning wheel 53, a synchronization tensioning belt 54, a synchronization tensioning slide 55 and a synchronization tensioning spring 56. The synchronization tensioning slide 55 is slidably arranged on the polishing mounting frame 11, and the synchronization tensioning wheel 53 is rotatably arranged at the lower end of the synchronization tensioning slide 55. The synchronization tensioning spring 56 is sleeved on the synchronization tensioning slide 55, and the synchronization tensioning spring 56 drives the synchronization tensioning slide 55. Move to the side away from the head fixing mechanism 4, the first synchronous rotating wheel 51 is connected to the main power roller 14 in transmission, the second synchronous rotating wheel 52 is connected to the intermediate roller 17 in rotation, and the synchronous tensioning belt 54 is sleeved on the first synchronous rotating wheel 51, the second synchronous rotating wheel 52 and the synchronous tensioning wheel 53. The synchronous component 5 is set up, which can make the main power roller 14 drive the intermediate roller 17 to rotate synchronously, thereby improving the transmission smoothness of the polishing belt 15 on the intermediate roller 17 and preventing the polishing belt 15 from getting stuck during operation.

[0043] In some embodiments, the head fixing mechanism 4 includes a head rotating motor 41, a head rotating base 42, and a head limiting assembly 43. The lower end of the head rotating base 42 is provided with a base mounting drum 44, and the base mounting drum 44 is rotatably set on the mounting table 3. The head limiting assembly 43 is set on the upper end surface of the head rotating base 42. The head rotating motor 41 is set on the mounting table 3 and is rotatably connected to the base mounting drum 44. The head is set on the head rotating base 42, and then the head is fixed by the head limiting assembly 43. Then, the head rotating base 42 and the head on it are driven to rotate by the head rotating motor 41, so that the polishing mechanism 1 can polish the outer surface of the head.

[0044] In this solution, a mounting bearing can be provided on the outer side of the base mounting drum 44 , and the mounting bearing can improve the rotation flexibility of the base mounting drum 44 on the mounting platform 3 .

[0045] In some embodiments, the head limiting assembly 43 includes a limiting plate 431, a limiting slide 432, a limiting outer cylinder 433, a limiting inner cylinder 434 and a gas control unit 435. The limiting plate 431 is fixedly mounted on the upper end surface of the head rotating base 42. A limiting slide groove 4311 is provided on the inner side of the limiting plate 431. A ventilation cavity 4312 is provided in the middle of the limiting plate 431. The ventilation cavity 4312 is connected to the limiting slide groove 4311. The limiting slide rod 432 is slidably set in the limiting slide groove 4311. The limiting outer cylinder 433 is inserted in the ventilation cavity 4312. The limiting inner cylinder 434 is arranged on the inner side of the limiting outer cylinder 433, and the limiting inner cylinder 434 is connected to the outer side of the limiting plate 431. A limiting piston 4321 is provided on the side of the limiting slide rod 432 close to the vent cavity 4312. The outer wall of the limiting piston 4321 is airtightly matched with the inner wall of the limiting slide groove 4311. The gas control unit 435 is respectively connected to the limiting inner cylinder 434 and the limiting outer cylinder 433. The gas control unit 435 generates positive pressure to be connected to the limiting outer cylinder 433, and the gas control unit 435 generates positive and negative pressure to be connected to the limiting inner cylinder 434.

[0046] The positive pressure airflow generated by the gas control unit 435 is delivered to the limiting outer cylinder 433, and the airflow in the limiting outer cylinder 433 enters the limiting slide groove 4311. At this time, the air pressure in the limiting slide groove 4311 will push the limiting piston 4321 to move the limiting slide rod 432 outward, and a contact portion is provided on the outer side of the limiting slide rod 432 so that the contact portion on the outer side of the limiting slide rod 432 is in conflict with the inner side wall of the head. Therefore, this solution provides at least two limiting slide rods 432 to be able to conflict with the inner side wall of the head, thereby realizing the limiting fixation of the head and ensuring the coaxiality of the head setting, so as to facilitate the subsequent polishing effect of the outer side wall of the head by the polishing mechanism 1;

[0047] The gas control unit 435 generates negative pressure to the limiting inner cylinder 434, and the gas in the head is extracted through the limiting inner cylinder 434, so that the cavity formed between the head and the head rotating base 42 is in a negative pressure state, so that the head is tightly adsorbed on the head rotating base 42. In this solution, there is no need to use a clamp to fix the head, thereby ensuring the integrity of the head outer surface, and at the same time, it can also meet the polishing integrity of the head outer surface of the polishing mechanism 1;

[0048] On this basis, a rubber layer is further provided on the upper surface of the head rotating base 42 in this solution, so as to ensure the airtightness of the head when it is fixed.

[0049] In some embodiments, a spring column can be mounted on the limit slide 432 in this solution. The spring column provides a certain damping force for the movement of the limit slide 432. When the limit slide 432 loses the gas thrust, it can be reset in time, thereby ensuring the stability of the limit slide 432 during movement.

[0050] like Figure 10 As shown, implementation mode 1 of the gas control unit 435: the gas control unit 435 includes a positive pressure fan 4351 and a negative pressure fan 4352, the positive pressure fan 4351 is connected to the limiting outer cylinder 433, and the negative pressure fan 4352 is connected to the limiting inner cylinder 434. The positive pressure generated by the positive pressure fan 4351 drives the limiting slide rod 432 to position the head, and the negative pressure generated by the negative pressure fan 4352 allows the head to be adsorbed on the head rotating base 42, thereby fixing the closed head.

[0051] like Figure 11 As shown, the second embodiment of the gas control unit 435: the gas control unit 435 includes a gas control cylinder 4353, a gas control piston 4354 and a gas control electric cylinder 4355. The gas control piston 4354 is slidably arranged in the gas control electric cylinder 4355. The gas control piston 4354 separates the inner side wall of the gas control cylinder 4353 into an inner cylinder air cavity 4356 and an outer cylinder air cavity 4357. The inner cylinder air cavity 4356 is connected to the limiting inner cylinder 434, and the outer cylinder air cavity 4357 is connected to the outer cylinder air cavity 4357. The gas control electric cylinder 4355 is connected to the gas control piston 4353. 4. The gas control electric cylinder 4355 drives the gas control piston 4354 to move in the gas control cylinder 4353. By controlling the gas control piston 4354 to move in the gas control cylinder 4353, the gas in the outer tube air cavity 4357 is withdrawn outward, so that the gas in the outer tube air cavity 4357 enters the limiting outer tube 433, thereby driving the limiting slide 432 to position the head. At the same time, the gas control piston 4354 moves to increase the space of the inner tube air cavity 4356, thereby generating suction, and sucking the gas in the cavity between the head and the head rotating base 42 into the inner tube air cavity 4356, thereby fixing the head.

[0052] In some embodiments, the moving mechanism 2 includes a horizontal moving electric cylinder 21, a vertical moving frame 22, a vertical moving motor 23, and a vertical moving screw rod 24. The vertical moving frame 22 is vertically mounted on the horizontal moving electric cylinder 21. The horizontal moving electric cylinder 21 drives the vertical moving frame 22 to move horizontally. The vertical moving screw rod 24 is rotatably arranged on the vertical moving frame 22. The vertical moving motor 23 is fixedly mounted on the vertical moving frame 22. The vertical moving motor 23 is transmission-connected to the vertical moving screw rod 24. The side of the polishing mounting frame 11 A vertical moving slider 111 is provided at the end, and a screw groove is provided on the vertical moving slider 111. The vertical moving screw 24 passes through the screw groove on the vertical moving slider 111. The vertical moving screw 24 rotates to drive the polishing mounting frame 11 to move in the vertical direction. The vertical moving electric cylinder 21 is provided to drive the vertical moving frame 22 to move in the horizontal direction. The vertical moving motor 23 is provided to drive the vertical moving screw 24 to rotate, and the polishing mounting frame 11 is driven to move in the vertical direction by the cooperation of the vertical moving screw 24 and the vertical moving slider 111.

[0053] When using this solution, the head is first placed on the head rotating base 42, so that the opening of the head is in contact with the upper end surface of the head rotating base 42. At this time, the gas control unit 435 is started, and the positive pressure gas drives the limit slide 432 to position the head, so that the cavity between the head and the head rotating base 42 forms a negative pressure to fix the head. Then, the moving mechanism 2 is started, and the polishing mechanism 1 is driven by the moving mechanism 2 to move to the head part, so that the polishing belt 15 and the outer surface of the head are in contact with each other. Then, the polishing motor 16 is started, and the polishing belt 15 is driven to run by the polishing motor 16. At this time, the polishing belt 15 polishes the outer surface of the head. Then, the head rotating motor 41 is started, and the head rotating base 42 is driven by the head rotating motor 41 to rotate synchronously, so that the head can be fully polished.

[0054] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
