Description

Technical Field

[0001] The present invention relates to the technical field of safe processing, and specifically to a production and processing device for safe components. Background Art

[0002] A safe is a security container used for storing valuables and important documents, and usually has functions such as anti-prying, anti-drilling, and fire prevention. A safe usually consists of many parts, and the outer shell of the safe is an important part of the safe structure, playing a crucial role in the safety of the safe. After the main structure of the safe outer shell is formed, it needs to be spray-painted to improve the protection and wear resistance of the safe outer shell.

[0003] The existing spraying method for the safe outer shell usually uses a clamping and positioning device to position the safe outer shell, and then an operator holds a spray gun to spray the four side surfaces (i.e., the side surfaces perpendicular to the opening position) of the positioned safe outer shell at the front, rear, left, and right positions, and then sprays the side surface of the safe outer shell at the top position.

[0004] When spraying the positioned safe outer shell by the above spraying method, although it can ensure that the side surfaces of the safe outer shell perpendicular to the opening position are fully sprayed, during the process of spraying with a hand-held spray gun, it is difficult to accurately control the distance between the spray gun and the side surface of the safe outer shell perpendicular to the opening position, resulting in the paint not being evenly sprayed on the side surface of the safe outer shell perpendicular to the opening position. And because after the safe outer shell is processed, there will be a phenomenon of partial protrusions on the surface of the side perpendicular to the opening due to improper cutting process during the processing, which leads to the paint not being able to evenly cover the side surface of the safe outer shell perpendicular to the opening position during spraying. And using the manual grinding method cannot ensure the flatness of the side surface of the safe outer shell perpendicular to the opening after grinding, thus affecting the uniformity of the paint distribution after spraying.

[0013] The beneficial effects of the present invention are as follows: First, the present invention uses a spraying unit to uniformly and comprehensively spray all sides of the safe shell perpendicular to the opening. The nozzle is driven by a first electric slider to move up and down reciprocally, and the cooperation of the vertical rod and the baffle enables the nozzle to adaptively adjust the angle according to different positions of the side of the safe shell perpendicular to the opening, thereby avoiding the situation where the spraying unit sprays perpendicular to the side of the safe shell perpendicular to the opening, further increasing the uniformity of spraying and preventing paint splashing.

[0014] Second, the present invention adjusts the sliding sleeve, the sliding column, and the positioning and blocking element according to the opening size of the safe shell through a synchronous adjustment element, so that the positioning and blocking element can accurately position the opening of the safe shell. The length formed by the sliding sleeve and the sliding column is adjusted through the second connecting rod and the first connecting rod, so as to pre-adjust the position of the positioning and blocking element. Moreover, the second connecting rod and the first connecting rod on the front and rear sides can be pre-adjusted first, so as to perform targeted adjustment according to the length and width dimensions of the opening of the safe shell, thereby increasing the accuracy of the positioning of the positioning and blocking element on the safe shell and increasing the applicability of the present invention.

[0015] Third, the right-angle sliding sleeve and the middle-position column move along with the movement of the sliding sleeve and the sliding column, so as to be adjusted according to the size of the safe shell. In addition, the downward extension plate and the right-angle extension plate can also block the flying paint during the spraying process, thereby preventing too much paint from adhering to the inside of the safe shell and affecting the subsequent processing of the inside of the safe shell. In addition, the positioning and blocking element can also automatically adjust the spraying distance in cooperation with the spraying unit, so that the distances between the spraying unit and the sides of the safe shell perpendicular to the opening are equal during the spraying process, thereby making the spraying more uniform.

[0016] Fourth, the present invention uses a grinding unit to comprehensively grind the safe shell, and the power assembly enables the vertical grinding plate to continuously press against the side of the safe shell perpendicular to the opening, thereby ensuring the grinding effect of the vertical grinding plate on the side of the safe shell, and further ensuring the uniformity of the spraying of the spraying unit on the side of the safe shell perpendicular to the opening by eliminating the unevenness of the side of the safe shell.

[0033] The embodiments of the present invention will be described in detail below. The embodiments described below are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention. For those not specified in the embodiments regarding specific technologies or conditions, they shall be carried out according to the technologies or conditions described in the literature in this field or according to the product specifications.

[0034] Refer to Figure 1 、 Figure 2 and Figure 9 , a production and processing device for a safe component, including a spraying area plate 1. A first motor 2 is installed on the top of the spraying area plate 1 through a motor box. The output end of the first motor 2 is installed with a rotating clamping unit 3. On the top of the spraying area plate 1 and symmetrically arranged on the left and right sides of the first motor 2 are grinding units 4. A power component 11 is commonly connected between the two grinding units 4. A spraying unit 5 is installed on the top of the spraying area plate 1 and behind the first motor 2.

[0035] The present invention pre-polishes the side of the safe outer shell perpendicular to the opening through the polishing unit 4, and then performs equidistant inclined spraying on different positions of the side of the safe outer shell perpendicular to the opening through the spraying unit 5, so as to enhance the spraying effect on the side of the safe outer shell perpendicular to the opening. In addition, by rotating the clamping unit 3, the safe outer shell with different opening sizes can be clamped, thereby increasing the applicability of the present invention.

[0036] Specifically, first, the structure of the rotating clamping unit 3 is adjusted according to the opening size of the safe outer shell to be sprayed, so that the rotating clamping unit 3 can accurately position the safe outer shell to be sprayed. Then, the safe outer shell is sleeved on the rotating clamping unit 3 with the opening facing downwards, and then the rotating clamping unit 3 is controlled to clamp and position the safe outer shell.

[0037] After the rotating clamping unit 3 completes the clamping and positioning of the safe, the power assembly 11 drives the polishing unit 4 to fit the side of the safe outer shell, and the polishing unit 4 polishes the side of the safe outer shell. After the safe is polished, the power assembly 11 moves the polishing unit 4 away from the safe outer shell, and then controls the first motor 2 to drive the rotating clamping unit 3 and the safe outer shell to rotate, so that the safe outer shell rotates 90 degrees. After the rotation of the safe outer shell is completed, the power assembly 11 is again controlled to drive the polishing unit 4 to fit the side of the safe outer shell and perform polishing. After all the sides of the safe outer shell perpendicular to the opening are polished, the power assembly 11 is controlled to drive the polishing unit 4 away from the safe outer shell, and the first motor 2 is controlled to drive the rotating clamping unit 3 and the safe outer shell to continuously rotate, and the spraying unit 5 is controlled to perform a full spraying on the side of the safe outer shell.

[0038] Refer to Figure 4 、 Figure 6 and Figure 9, the rotating clamping unit 3 includes a rotating disk 31 fixed to the output end of the first motor 2. A locking element 32 is provided at the bottom of the rotating disk 31. A hollow column 311 is fixed to the top of the rotating disk 31. Four sliding columns 312 are circumferentially and evenly slidably connected to the middle of the hollow column 311. The four sliding columns 312 are respectively perpendicular to the opening. One ends of the four sliding columns 312 located inside the hollow column 311 are all fixed with pushed blocks 313. A cylinder 314 is installed at the bottom of the hollow part of the hollow column 311. The pushing end of the cylinder 314 is connected with a cross-shaped pushing block 316 through an upward extension rod 315. The cross-shaped pushing block 316 is used to push all the pushed blocks 313 synchronously; a square plate 317 is fixed to the bottom of the sliding column 312. A tension spring 318 is connected between the square plate 317 and the hollow column 311. Sliding sleeves 319 are sleeved on one ends of the four sliding columns 312 located outside the hollow column 311. A synchronous adjustment element 33 for adjusting the distance between the two is connected between the sliding sleeve 319 and the sliding column 312. A positioning and blocking element 34 is jointly fixed among the four sliding sleeves 319.

[0039] The rotating clamping unit 3 is used to clamp and position the safe outer shell with different opening sizes, so that the safe outer shell clamped and completed by the continuous drive of the first motor 2 can rotate, so as to spray the side surface of the safe outer shell perpendicular to the opening comprehensively. At the same time, the positioning and blocking element 34 can be used to position the opening of the safe outer shell, and it can prevent the paint from entering the inside of the safe outer shell during spraying and affecting the subsequent spraying inside the safe outer shell.

[0040] Specifically, first, according to the size of the opening of the safe outer shell, the length formed by the sliding sleeve 319 and the sliding column 312 is adjusted by the synchronous adjustment element 33. After the length formed by the sliding sleeve 319 and the sliding column 312 is adjusted, the opening of the safe outer shell to be sprayed is placed downward and corresponds to the position length of the positioning and blocking element 34. After the inner wall of the safe outer shell abuts against the top of the hollow column 311, the cylinder 314 is controlled to push the cross-shaped pushing block 316 upward. The cross-shaped pushing block 316 will push all the sliding columns 312 outward through the pushed blocks 313. Due to the pressing action of the synchronous adjustment element 33, all the sliding sleeves 319 and sliding columns 312 can move outward synchronously, so that the sliding sleeves 319 and sliding columns 312 drive the positioning and blocking element 34 to position the safe outer shell.

[0041] Refer to Figure 3 、 Figure 4 、 Figure 6 and Figure 7, the synchronous adjustment element 33 includes a first connecting rod 331 hinged to the top of the sliding column 312. One end of the first connecting rod 331 away from the sliding column 312 is hinged with a second connecting rod 332. One end of the second connecting rod 332 away from the first connecting rod 331 is hinged to the top of the sliding sleeve 319 at the corresponding position. A downward pushing structure for synchronously pushing the second connecting rod 332 and the first connecting rod 331 is arranged on the side of the hollow column 311.

[0042] The downward pushing structure includes a threaded section arranged on the side of the hollow column 311. A rotating ring 333 is threadedly connected to the side of the hollow column 311 at its threaded section position. A moving ring 334 is rotatably installed at the bottom of the rotating ring 333. A limiting plate slidably connected to the hollow column 311 is arranged inside the moving ring 334. Fixed downward pushing plates 335 are symmetrically fixed on the left and right sides of the moving ring 334. Extension plates 336 are symmetrically fixed on the front and rear sides of the moving ring 334. The rear extension plate 336 is connected with an adjusting screw rod 337. A positioning ring 338 is slidably connected to the side of the moving ring 334 and above the fixed downward pushing plate 335. The lower end of the adjusting screw rod 337 is rotatably installed on the positioning ring 338. The front end of the top of the positioning ring 338 is limited by a positioning rod passing through the front extension plate 336. Moving downward pushing plates 339 are symmetrically fixed on the front and rear sides of the bottom of the positioning ring 338.

[0043] The synchronous adjustment element 33 is used to adjust the sliding sleeve 319, the sliding column 312 and the positioning and blocking element 34 according to the opening size of the safe outer shell, and adopt different adjustment methods according to whether the opening shape of the safe outer shell is a cuboid or a cube. If the opening shape of the safe outer shell is a cuboid, the second connecting rods 332 and the first connecting rods 331 on the front and rear sides are pre-adjusted first. If the opening shape of the safe outer shell is a cube, the length formed by all the combinations of the sliding sleeves 319 and the sliding columns 312 is directly adjusted through the second connecting rods 332 and the first connecting rods 331.

[0044] Specifically, first, the rotating ring 333 is rotated according to the size of the opening of the safe outer shell, so that the moving ring 334 moves downward and drives the fixed downward pushing plate 335 to push downward or away from the second connecting rod 332 and the first connecting rod 331 at the corresponding position, and makes the sliding sleeve 319 move outward relative to the sliding column 312. Subsequently, the adjusting screw rod 337 drives the positioning ring 338 to move up and down, so as to drive the moving downward pushing plate 339 to move up and down relative to the fixed downward pushing plate 335, so as to push or move away from the second connecting rod 332 and the first connecting rod 331 at the corresponding position, so that after the adjustment is completed, the positioning and blocking element 34 can accurately position the safe outer shell after the sliding sleeve 319 and the sliding column 312 are pushed by the cross push block 316.

[0045] Refer to Figure 7, in this embodiment, to avoid the phenomenon that the second connecting rod 332 and the first connecting rod 331 are damaged due to long-term pressing and friction with the fixed lower push plate 335 and the moving lower push plate 339, a pressing roller is provided at the hinge joint of the second connecting rod 332 and the first connecting rod 331. Through the pressing roller, the friction fit between the second connecting rod 332 and the first connecting rod 331 and the fixed lower push plate 335 and the moving lower push plate 339 is changed into a rolling fit, so as to ensure the service life of the second connecting rod 332 and the first connecting rod 331.

[0046] Refer to Figure 4 , Figure 6 and Figure 8 , the positioning and blocking element 34 includes a middle column 341 fixed on the sliding sleeve 319. An inner spring is connected between the middle column 341 and the corresponding sliding column 312. A right-angle sliding sleeve 342 is sleeved between every two adjacent middle columns 341. An avoidance groove is provided at the bottom of the right-angle sliding sleeve 342. A downward extension plate 343 is fixed at the bottom of the middle column 341 and corresponding to the avoidance groove. A right-angle baffle 344 is fixed at the bottom of each right-angle sliding sleeve 342. A guiding slope is provided at the position where every two right-angle baffles 344 are close to each other.

[0047] The positioning and blocking element 34 can move with the sliding sleeve 319 and the sliding column 312 through the right-angle sliding sleeve 342 and the middle column 341, so as to be adjusted according to the size of the safe outer shell. In addition, the downward extension plate 343 and the right-angle baffle 344 can also block the flying paint during the spraying process, so as to prevent too much paint from adhering to the inside of the safe outer shell and affecting the subsequent processing of the inside of the safe outer shell. In addition, the positioning and blocking element 34 can also cooperate with the spraying unit 5 to automatically adjust the spraying distance, so that the distances between the spraying unit 5 and the side surface of the safe outer shell perpendicular to the opening are equal during the spraying process, and thus the spraying is more uniform.

[0048] Specifically, when the control synchronous adjustment element 33 adjusts the positions of the sliding sleeve 319 and the sliding column 312, the middle column 341 will move with the changes in the positions of the sliding sleeve 319 and the sliding column 312, and drive the right-angle sliding sleeve 342 between the two through the two middle columns 341. When the cross push block 316 is subsequently controlled to push the sliding sleeve 319 and the sliding column 312, the sliding sleeve 319 and the sliding column 312 will move outwards, so that the middle column 341 moves outwards, and the right-angle sliding sleeve 342 is driven to move again due to the movement of the middle column 341, so as to accurately position the opening position of the safe outer shell.

[0049] Refer to Figure 4 and Figure 9, the locking element 32 includes a stable chute 321 fixed to the top of the spraying area plate 1. A stable sliding ring 322 that mates with the stable chute 321 is fixed to the bottom of the rotating disc 31. Positioning holes 323 are provided at positions corresponding to each sliding column 312 on the stable sliding ring 322. A fixing plate 324 is fixed to the top of the spraying area plate 1 and located on the front side of the stable sliding ring 322. A positioning pin 325 that mates with the positioning holes 323 is longitudinally slidably connected to the middle of the fixing plate 324. A spring plate 326 is provided at the position between the fixing plate 324 and the stable sliding ring 322 on the positioning pin 325. A compression spring is connected between the spring plate 326 and the fixing plate 324.

[0050] The locking element 32 is used to precisely control the rotation angle during the process of the first motor 2 driving the rotating clamping unit 3 and the safe outer shell to rotate, so as to facilitate the grinding unit 4 to grind the side surface of the switched safe outer shell. Moreover, it can make the rotating clamping unit 3 and the safe outer shell stable during the rotation process with the cooperation of the stable sliding ring 322 and the stable chute 321. At the same time, it can also make the safe outer shell stable during the grinding process with the cooperation of the positioning holes 323 and the positioning pins 325, thereby ensuring the grinding effect of the grinding unit 4 and further ensuring the spraying effect during the spraying process.

[0051] Specifically, during the process of the positioning and blocking element 34 positioning the safe outer shell, the positioning pin 325 is inserted into the positioning hole 323 to stabilize the positioning and blocking element 34. After the positioning and blocking element 34 completes the positioning of the safe outer shell, control the power assembly 11 to drive the grinding unit 4 to press against the safe outer shell, and control the grinding unit 4 to grind the side surface of the safe outer shell. After the grinding is completed, control the power assembly 11 to drive the grinding unit 4 away from the safe outer shell. Subsequently, control the first motor 2 to drive the rotating clamping unit 3 and the safe outer shell to rotate. During the rotation process, first, the operator pulls out the positioning pin 325 to facilitate the rotation of the rotating clamping unit 3. During the rotation process, release the positioning pin 325, and the positioning pin 325 will press against the stable sliding ring 322. After the safe outer shell rotates 90 degrees, the positioning pin 325 will quickly snap into the positioning hole 323 due to the action of the compression spring, making the position of the safe outer shell stable. Subsequently, control the power assembly 11 to drive the grinding unit 4 to press against the safe outer shell again, and use the grinding unit 4 to grind the other set of side surfaces of the safe outer shell.

[0052] Refer to Figure 5 and Figure 10 , in this embodiment, in order to enable the safe outer shell to continuously rotate during the spraying process of the spraying unit 5 on the safe outer shell, a vertical buckle is slidably connected to the front side of the fixing plate 324. By pressing down the buckle, the front and rear positions of the positioning pin 325 are limited, so that the first motor 2 can drive the rotating clamping unit 3 and the safe outer shell to continuously rotate.

[0053] Refer to Figure 2 and Figure 11 Figure 11 , the grinding unit 4 includes a longitudinal plate 41 fixed to the top of the spraying area plate 1. A limiting rod 411 is fixed between the two longitudinal plates 41. A moving plate 412 is jointly arranged on the limiting rod 411 and the power assembly 11. A moving grinding element 42 is fixed to the top of each moving plate 412; the moving grinding element 42 includes a longitudinal slide rail 421 fixed to the top of the moving plate 412. A displacement block 422 is connected to the longitudinal slide rail 421 through a second electric slider. Vertical grinding plates 423 are fixed to the opposite sides of the two displacement blocks 422.

[0054] The power assembly 11 includes a bidirectional threaded rod 111 rotatably installed on the right side of the left longitudinal plate 41. The right end of the bidirectional threaded rod 111 penetrates through the right longitudinal plate 41. A second motor 112 is installed on the right side of the right longitudinal plate 41 through a motor sleeve. The output end of the second motor 112 is connected to the right end of the bidirectional threaded rod 111. The bidirectional threaded rod 111 is connected to each moving plate 412 in a threaded fit manner.

[0055] The grinding unit 4 is used to comprehensively grind the outer shell of the safe, and the power assembly 11 can make the vertical grinding plate 423 continuously press against the side of the safe perpendicular to the opening, so as to ensure the grinding effect of the vertical grinding plate 423 on the side of the safe, and then ensure the uniformity of the spraying on the side of the safe perpendicular to the opening by eliminating local protrusions and unevenness on the side of the safe.

[0056] Specifically, after the positioning and blocking element 34 completes the positioning of the safe outer shell, control the second motor 112 to drive the bidirectional threaded rod 111 to move the two moving plates 412 towards the safe outer shell until the vertical grinding plate 423 presses against the side of the safe perpendicular to the opening. Then, drive the displacement block 422 and the vertical grinding plate 423 to perform a reciprocating motion back and forth through the second electric slider, so as to grind the side of the safe perpendicular to the opening with the vertical grinding plate 423. Then, drive the vertical grinding plate 423 away from the side of the safe perpendicular to the opening through the power assembly 11, and rotate the safe outer shell 90 degrees through the locking element 32 in cooperation with the first motor 2 and the rotating clamping unit 3. Then, repeat the above grinding operation on the side of the safe perpendicular to the opening, so that all sides of the safe perpendicular to the opening are comprehensively ground, and then all sides of the safe perpendicular to the opening are flattened.

[0057] Refer to Figure 2 、 Figure 12 and Figure 13, the spraying unit 5 includes a vertical plate 51 fixed to the top of the spraying area plate 1. A moving spraying element 52 for cooperating with and positioning the blocking element 34 is provided on the vertical plate 51; the moving spraying element 52 includes a receiving push rod 521 penetrating through the vertical plate 51. The front end of the receiving push rod 521 abuts against the rear side of the lower extension plate 343 at the rear. A circular plate 522 is fixed to the rear end of the receiving push rod 521. A connecting spring is connected between the circular plate 522 and the vertical plate 51. An installation plate 523 is fixed on the receiving push rod 521 and on the front side of the vertical plate 51. The installation plate 523 is limited by a rear extension rod penetrating through the vertical plate 51. A vertical slide rail 524 is fixed to the front side of the installation plate 523. An installation frame 525 is installed on the vertical slide rail 524 through a first electric slider. A spray head 526 is rotatably installed in the middle of the installation frame 525. A torsion spring for rotating the spray head 526 to the left is provided at the rotating position of the spray head 526 and the installation frame 525. A vertical rod 527 is fixed to the left side of the spray head 526; a blocking plate 529 for pushing the vertical rod 527 is fixed to the left side of the vertical plate 51 through an L-shaped column 528; the middle of the longitudinal end of the L-shaped column 528 is an adjustable telescopic structure.

[0058] The spraying unit 5 is used to uniformly and comprehensively spray all sides of the safe outer shell perpendicular to the opening. The first electric slider cooperates with the vertical slide rail 524 to make the spray head 526 reciprocate up and down. At the same time, the receiving push rod 521 can cooperate with the lower extension plate 343 and the right-angle baffle 344 to automatically adjust the distance between the spray head 526 and all sides of the safe outer shell perpendicular to the opening as all sides of the safe outer shell perpendicular to the opening rotate. And with the cooperation of the vertical rod 527 and the blocking plate 529, the spray head 526 can perform adaptive angle adjustment according to different positions of all sides of the safe outer shell perpendicular to the opening, thereby avoiding the situation of spraying on the side of the safe outer shell perpendicular to the opening. While further increasing the uniformity of spraying, it can prevent paint splashing.

[0059] Specifically, after the synchronous adjustment element 33 adjusts the sliding sleeve 319, the sliding column 312 and the positioning and blocking element 34, the lower extension plate 343 will then press against the receiving push rod 521 backward, thereby pre-adjusting the distance between the spray head 526 and the safe outer shell. After the grinding unit 4 finishes grinding all sides of the safe outer shell perpendicular to the opening, the control unit controls the first motor 2 to drive the rotating clamping unit 3 and the safe outer shell to continuously rotate counterclockwise. At this time, due to the pressing action of the right-angle baffle 344, the receiving push rod 521 moves backward, and the spray head 526 that was originally rotated to the left due to the torsion spring will also move backward together. After the vertical rod 527 is blocked by the blocking plate 529, it rotates to be parallel to the receiving push rod 521. At this time, the vertical side of the safe outer shell just aligns with the spray head 526, so that the spray head 526 uniformly and effectively sprays the side of the safe outer shell perpendicular to the opening in an inclined spraying manner throughout the process.

[0060] It should be noted that the right end of the nozzle 526 is connected to an external paint supply unit through a connecting pipe, so as to ensure that the nozzle 526 can spray the paint evenly.

[0061] The working steps of the present invention are as follows: First step, first adjust the structure of the rotating clamping unit 3 according to the opening size of the safe outer shell to be sprayed. The main adjustment is to adjust the length formed by the sliding sleeve 319 and the sliding column 312 by the synchronous adjustment element 33. After the adjustment is completed, the positioning and blocking element 34 can accurately position the safe outer shell. Subsequently, place the safe outer shell to be sprayed with the opening facing down and corresponding to the position length of the positioning and blocking element 34.

[0062] Second step, after the opening of the safe outer shell is pressed against the top of the hollow column 311 with the opening facing down, control the air cylinder 314 to push the cross push block 316 upward. The cross push block 316 will push all the sliding columns 312 outward through the pushed block 313. Due to the pressing action of the synchronous adjustment element 33, all the sliding sleeves 319 and the sliding columns 312 can move outward synchronously, so that the sliding sleeves 319 and the sliding columns 312 drive the positioning and blocking element 34 to position the safe outer shell.

[0063] Third step, when the positioning and blocking element 34 completes the positioning of the safe outer shell, control the second motor 112 to drive the bidirectional threaded rod 111 to make the two moving plates 412 move towards the safe outer shell until the vertical grinding plate 423 is pressed against the side of the safe outer shell perpendicular to the opening. Subsequently, drive the displacement block 422 and the vertical grinding plate 423 to perform a reciprocating motion back and forth through the second electric slider, so as to grind the side of the safe outer shell perpendicular to the opening with the vertical grinding plate 423.

[0064] Fourth step, after the grinding unit 4 finishes grinding a group of sides of the safe outer shell perpendicular to the opening, drive the vertical grinding plate 423 to move away from the side of the safe outer shell perpendicular to the opening through the power assembly 11, and drive the safe outer shell to rotate 90 degrees through the locking element 32 in cooperation with the first motor 2 and the rotating clamping unit 3. Subsequently, repeat the above grinding operation on the side of the safe outer shell perpendicular to the opening, so that all sides of the safe outer shell perpendicular to the opening are comprehensively ground, and further make all sides of the safe outer shell perpendicular to the opening flat.

[0065] In the fifth step, after all the sides of the safe outer shell perpendicular to the opening are polished in the polishing unit 4, control the first motor 2 to drive the rotating clamping unit 3 and the safe outer shell to rotate continuously counterclockwise. At this time, continuously pull forward through the positioning pin 325 of the buckle. During the continuous counterclockwise rotation of the safe outer shell, due to the pressing action of the right-angled baffle 344, the receiving push rod 521 moves backward, and the spray head 526 that originally rotated to the left due to the action of the torsion spring will move backward together. After the vertical rod 527 is blocked by the blocking plate 529, it rotates to be parallel to the receiving push rod 521. At this time, the vertical side of the safe outer shell just aligns with the spray head 526. After the safe outer shell continues to rotate, the spray head 526 will move forward along with the receiving push rod 521 and return to the initial angle due to the action of the torsion spring. Thus, during the whole process, the spray head 526 uniformly and effectively sprays the side of the safe outer shell perpendicular to the opening in an inclined spraying manner.
