[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] This embodiment relates to a trimming device for blow molding of oil drums. In terms of overall structure, as follows... Figure 1 and Figure 3 As shown, it includes a base 1, a clamping mechanism 2, a multi-stage drive mechanism 3, and a cutting mechanism 4.

[0023] Among them, an L-shaped platform 101 is fixedly installed on the top of one side of the base 1, and a sliding groove 102 is longitudinally opened on the bottom of the other side of the base 1. The clamping mechanism 2 is fixedly installed on the top of the base 1, and the multi-stage drive mechanism 3 is slidably installed on the other side of the base 1. The multi-stage drive mechanism 3 includes a C-shaped frame 301 slidably installed on the sliding groove 102, a support platform 302 slidably installed on the C-shaped frame 301, and an annular support frame 303 fixedly installed on the top of the support platform 302. An annular slide rail 304 is fixedly installed on the side of the annular support frame 303 near the L-shaped platform 101, and a slider 305 is slidably installed on the annular slide rail 304. The edge cutting mechanism 4 is fixedly installed on the slider 305.

[0024] It is worth mentioning that the L-shaped platform 101 is fixedly installed on the top of the base 1, with the top end near the side of the base 1 being higher. The C-shaped frame 301 is longitudinally installed on the base 1 on the side away from the L-shaped platform 101, and the support plates on both sides of the C-shaped frame 301 are installed vertically upward on the base 1 to support the sliding installation of the support platform 302 on the C-shaped frame 301. The support platform 302 is slidably installed on the upper inner part of the C-shaped frame 301 to support the fixed installation of the annular support frame 303. The annular support frame 303 is fixedly installed on the top of the support platform 302 to support the fixed installation of the annular slide rail 304. The slider 305 is slidably mounted on the annular slide rail 304, allowing the slider 305 to move circumferentially on the slide rail. One side of the clamping mechanism 2 passes through the inside of the annular support frame 303 and is fixedly mounted on the top of the side of the base 1, allowing the slider 305 on the annular slide rail 304 to move circumferentially around the outer edge of the oil drum. The up-and-down movement and back-and-forth movement of the multi-stage drive mechanism 3 will keep the annular support frame 303 and the clamping mechanism 2 at a certain distance. The trimming mechanism 4 is fixedly mounted on the slider 305. As the slider 305 moves circumferentially around the oil drum, the trimming mechanism 4 can trim each side of the oil drum.

[0025] As a preferred option, such as Figure 2 As shown, in this embodiment, a first sliding block 3011 is fixedly provided at the bottom of the C-shaped frame 301, a first sliding groove 3012 is symmetrically provided on the inner side of the C-shaped frame 301, a first cylinder 306 is fixedly provided on one side of the C-shaped frame 301 on the base 1, and the first sliding block 3011 is slidably installed on the sliding groove 102.

[0026] It should be noted that the first sliding block 3011 at the bottom of the convex frame 301 is slidably installed in the sliding groove 102 on the base 1, and the piston rod end of the first cylinder 306 is fixedly installed on the convex frame 301. The extension and retraction of the piston rod of the first cylinder 306 drives the convex frame 301 to move in the front-back direction, thereby driving the entire multi-stage drive mechanism 3 to move in the front-back direction. The first sliding groove 3012 is opened on the inner side of the two vertically upward support plates of the convex frame 301 to support the sliding installation of the support platform 302.

[0027] As a preferred option, it remains as follows Figure 2 As shown, in this embodiment, a second sliding block 3021 is fixedly provided on the front and rear sides of the support platform 302, and a second cylinder 307 is fixedly provided at the bottom of the support platform 302 at the middle position of the top of the C-shaped frame 301. The second sliding block 3021 is slidably provided on the first slide groove 3012.

[0028] Specifically, the second sliding blocks 3021 on the front and rear sides of the support platform 302 are slidably installed on the two first sliding grooves 3012 of the C-shaped frame 301. The end of the piston rod of the second cylinder 307 is fixedly installed at the middle position of the bottom of the support platform 302. The extension and retraction of the piston rod of the second cylinder 307 drives the support platform 302 to move up and down, thereby driving the annular support frame 303 and the annular slide rail 304 to move up and down.

[0029] As a preferred option, it remains as follows Figure 1 and Figure 3 As shown, in this embodiment, the trimming mechanism 4 includes a C-shaped mounting plate 401 fixedly mounted on the slider 305 and a servo motor 402 fixedly mounted on the C-shaped mounting plate 401. A mounting block 403 is fixedly mounted at the end of the output shaft of the servo motor 402. A double-rod cylinder 404 is fixedly mounted on the side of the mounting block 403 away from the servo motor 402. A cutter 405 is fixedly mounted at the end of the piston rod of the double-rod cylinder 404. A probe 406 is fixedly mounted on the mounting block 403.

[0030] Specifically, the C-shaped mounting plate 401 is fixedly mounted on the slider 305 with a nut. As the slider 305 moves, it supports the fixed mounting of the servo motor 402. The mounting block 403 is fixedly mounted on the output shaft of the servo motor 402. The double-rod cylinder 404 is fixedly mounted on the mounting block 403. The cutter 405 is fixedly mounted on the end of the piston rod of the double-rod cylinder 404. The rotation of the output shaft of the servo motor 402 at a certain angle drives the mounting block 403 and the double-rod cylinder 404 to rotate at a certain angle, thereby driving the cutter 405 to adjust the cutting angle, so that the cutter 405 can cut the various sides, bevels and curved corners of the oil drum. The probe 406 is fixedly mounted on the mounting block 403. After the probe 406 moves around the side of the oil drum with the mounting block 403, it transmits the information that the side of the oil drum needs to be cut to the central control system to control the coordination between the various devices.

[0031] As a preferred option, it remains as follows Figure 1 and Figure 3 As shown, in this embodiment, the clamping mechanism 2 includes a third cylinder 201 fixedly mounted on an L-shaped platform 101 and a mounting platform 202 fixedly mounted on the top of one side of the base 1. The mounting platform 202 is fixedly mounted on the side away from the third cylinder 201. A set of limiting grooves 203 are provided on the side of the mounting platform 202 near the third cylinder 201. A limiting slide rod 204 is slidably mounted on the limiting groove 203. A spring 205 is fixedly mounted on the limiting slide rod 204 inside the limiting groove 203. Clamping plates 206 are fixedly mounted on the piston rod end of the third cylinder 201 and the end of the limiting slide rod 204.

[0032] Specifically, the mounting platform 202 is fixedly installed on the top of the base 1 on the side away from the third cylinder 201 to support the installation of the limiting slide rod 204. There are two limiting grooves 203, which are opened on the side of the mounting platform 202 near the third cylinder 201 to support the limiting slide rod 204 to slide on the mounting platform 202. The two ends of the spring 205 are fixedly installed on the limiting slide rod 204 and the mounting platform 202 respectively, so that the limiting slide rod 204 returns to its initial position when no external force is applied.

[0033] The distance between the clamping plate 206 at the end of the piston rod of the third cylinder 201 and the end of the limiting slide rod 204 is 1.1 to 1.3 times the thickness of the oil drum, so that the oil drum can be placed on the L-shaped platform 101 between the two clamping plates 206, while preventing the oil drum from falling off the L-shaped platform 101. When clamping the oil drum, the oil drum is placed on the L-shaped platform 101 at the end of the clamping plate 206 of the third cylinder 201. The piston rod of the third cylinder 201 extends, so that the clamping plate 206 at the end of the piston rod of the third cylinder 201 and the end of the limiting slide rod 204 clamps the two sides of the oil drum. The limiting slide rod 204 moves in the limiting groove 203, so that the side of the bottom of the oil drum is separated from the L-shaped platform 101, which facilitates the trimming of each side of the oil drum.

[0034] The trimming device for blow molding of oil drums described in this utility model, through the setting of the clamping mechanism 2, ensures that the oil drum can be suspended and clamped, so that all the sides of the oil drum are exposed. Through the setting of the multi-stage drive mechanism 3, it ensures that the trimming mechanism 4 can trim each side of the oil drum, improving the trimming accuracy. Through the setting of the trimming mechanism 4, the cutter 405 can rotate 360°, ensuring that the corners of the oil drum can be trimmed.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
