DETAILED DESCRIPTION

[0030] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0031] See also Figure 1-7 The utility model provides a technical solution: an automatic feeding device of an iron can sealing machine, comprising a sealing machine body 1, a conveyor belt 2 is arranged inside the sealing machine body 1 for conveying iron cans, and limiting plates 4 are arranged on both sides of the conveyor belt 2, so that the iron cans on the conveyor belt 2 can be restricted by the setting of the limiting plates 4, thereby avoiding the iron cans from slipping on the conveyor belt 2 and ensuring the smooth transportation of the iron cans. A transfer mechanism 3 is arranged inside the sealing machine body 1 for transferring the iron cans to the lower part of the iron can sealing mechanism inside the sealing machine body 1, so that the iron can sealing mechanism can smoothly fix the iron can lid to the iron can. At the same time, the iron can sealing mechanism is a known technology to those skilled in the art, and its specific structure and working principle are known technologies, so they will not be discussed in detail here.

[0032] The transfer mechanism 3 includes a mounting frame 301, and a plurality of support rods 302 are fixedly connected to the inner bottom of the mounting frame 301 to support the mounting frame 301. A motor 307 is fixedly connected to the inner wall of the sealing machine body 1. The output end of the motor 307 passes through the surface of the mounting frame 301 and is rotatably connected to the inside of the mounting frame 301 to provide power for the transfer of the iron cans.

[0033] A rotating disk 303 is placed on the inner wall of the mounting frame 301. The rotating disk 303 is provided with arc-shaped notches arranged equidistantly around the circumference for hooking the iron cans, so that the iron cans can be transported when the rotating disk 303 rotates. The output end of the motor 307 slides with the inside of the rotating disk 303.

[0034] The transfer mechanism 3 also includes a connecting frame 304 with a cross-shaped cross section. The surface of the connecting frame 304 slides with the inside of the motor 307. The surface of the rotating disk 303 is fixedly connected with four bolts 306 arranged equidistantly in a circle. The surface of the bolt 306 slides with the inside of the connecting frame 304. The surface of the bolt 306 is threadedly connected with a nut 305. Then, through the arrangement of the nut 305 and the bolt 306, the connecting frame 304 can be inserted into the output end of the motor 307, and the connecting frame 304 and the motor 307 can be connected by using the nut 305 and the bolt 306. The rotating disk 303 is connected, and the connection between the motor 307 and the motor 307 can be realized, so that the output terminal of the motor 307 can smoothly drive the rotating disk 303 to rotate synchronously when rotating. At the same time, the rotating disk 303 and the motor 307 can be separated by removing the nut 305 and the connecting frame 304, which makes it convenient for the staff to replace the rotating disk 303, thereby facilitating the device to seal iron cans of different sizes, making the device adjustable, improving the use effect of the device, and worthy of promotion.

[0035] Furthermore, the inner wall of the mounting frame 301 is fixedly connected with equidistantly arranged top rods 308, the upper ends of the top rods 308 are spherical, and the upper ends of the top rods 308 are in contact with the bottom of the rotating disk 303 to support the rotating disk 303, thereby reducing the contact area between the rotating disk 303 and the mounting frame 301, making the rotation of the rotating disk 303 in the mounting frame 301 smoother, thereby improving the smoothness of the device during use and improving the use effect of the device.

[0036] The sealing machine body 1 is provided with an adjustment mechanism 5 inside, which includes two bent clamps 514, and the two clamps 514 are respectively connected to the opposite sides of the two limiting plates 4 by hinges to position the iron cans for transportation. The opposite sides of the two clamps 514 are slidably connected with clamping frames 515, and the interiors of the two limiting plates 4 are threadedly connected with second adjusting screws 513 that penetrate the surface of the limiting plates 4. The opposite ends of the two second adjusting screws 513 are rotatably connected with connecting blocks 524, and the surfaces of the two connecting blocks 524 are respectively rotatably connected to the inner walls of the two clamping frames 515. Then, through the setting of the second adjusting screw 513, the spring 526 and the clamping frame 515, the staff can adjust the deflection angle of the two clamps 514 on the conveyor belt 2 by rotating the second adjusting screw 513, thereby adjusting the distance between the vertical ends of the two clamps 514, so that the device can position iron cans of different sizes, thereby ensuring the versatility of the device.

[0037] Electric push rods 508 are provided on both sides of the conveyor belt 2. The two electric push rods 508 are mounted on the sealing machine body 1. The output ends of the two electric push rods 508 are fixedly connected to the fixing sleeves 510. The inner walls of the two fixing sleeves 510 are slidably connected to the sliding rods 511. The opposite ends of the two sliding rods 511 are fixedly connected to the clamping plates 512, which are used to clamp and fix the iron cans so that the iron cans cannot be further transported by the conveyor belt 2, thereby providing time for the iron can lids to be installed on the iron cans, ensuring that the iron cans are installed with lids, and thus ensuring that the subsequent devices can smoothly seal the iron cans.

[0038] Furthermore, the opposite ends of the two slide rods 511 are fixedly connected with springs 526, and the ends of the two springs 526 away from the slide rod 511 are respectively fixedly connected to the inner walls of the two fixed sleeves 510. Then, through the setting of the slide rod 511, a certain sliding distance is provided for the slide rod 511 in the fixed sleeve 510, thereby providing a certain retraction distance for the clamping plate 512, so that the two clamping plates 512 can clamp and fix iron cans of different sizes, ensuring the smooth operation of the device.

[0039] The surfaces of the two clamping plates 512 are fixedly connected with infrared sensors 525, and the infrared sensors 525 are electrically connected to the electric push rod 508. Therefore, through the setting of the infrared sensor 525, when the iron can passes through the infrared sensor 525, the infrared sensor 525 transmits a signal to the electric push rod 508, thereby driving the clamping plates 512 to successfully clamp and fix the iron can, ensuring that the device can successfully clamp and fix the iron can.

[0040] Furthermore, the adjustment mechanism 5 also includes two arc-shaped blanking plates 501, which penetrate the surface of the sealing machine body 1 and slide against the interior of the sealing machine body 1. The inner wall of the sealing machine body 1 is fixedly connected with a mounting plate 504. The two blanking plates 501 also penetrate the surface of the mounting plate 504 and slide against the interior of the mounting plate 504. The center of the two blanking plates 501 corresponds to the center of the two clamping plates 512, and at the same time provides a blanking space for the iron can lid. The top of the sealing machine body 1 is fixedly connected with two fixed blocks 502. The internal threads of the two fixed blocks 502 are connected with a first adjusting screw 503 that penetrates the interior of the fixed block 502. The opposite ends of the two first adjusting screws 503 are rotatably connected to the surfaces of the two blanking plates 501 respectively, and then through the setting between the two first adjusting screws 503, the staff can adjust the distance between the two blanking plates 501 by rotating the first adjusting screw 503, thereby completing the limiting of the non-standard iron can lid, which is convenient for the subsequent sealing of iron cans of different specifications.

[0041] Two rotating shafts 506 are mounted on the surface of the mounting plate 504, and push-pull disks 516 are fixedly connected to the surfaces of the two rotating shafts 506. Push-pull grooves 517 are provided on both sides of the surfaces of the two push-pull disks 516. The push-pull grooves 517 are composed of two arc-shaped grooves, one large and one small, and the two arc-shaped grooves are connected to each other, and the push-pull grooves 517 on both sides of the push-pull disks 516 are arranged in opposite directions. Two mounting blocks 519 are fixedly connected to the surface of the mounting plate 504, and the interiors of the two mounting blocks 519 are slidably connected with slides 520 that pass through the surfaces of the mounting blocks 519. The two slides 520 in the mounting blocks 519 are arranged up and down, and one end of the slide 520 is fixedly connected to a push-pull rod 518, and the surface of the push-pull rod 518 slides with the inner wall of the push-pull groove 517. In the initial state of the device, the push-pull rods 518 on both sides of the push-pull disk 516 are respectively located in the large arc groove and the small arc groove of the two push-pull grooves 517.

[0042] Furthermore, one end of the slide plate 520 away from the push-pull rod 518 is threadedly connected to a third adjusting screw 522, and the other end of the third adjusting screw 522 away from the slide plate 520 is rotatably connected to a support plate 521. The side of the support plate 521 away from the third adjusting screw 522 is tapered, which facilitates the insertion of the support plate 521 between the two iron can covers and ensures the smooth operation of the device. At the same time, since the two push-pull rods 518 are respectively located in the large arc groove and the small arc groove of the two push-pull grooves 517, the two support plates 521 are arranged one in front and one behind, that is, in the initial state, only one support plate 521 supports the bottom of the iron can cover. At the same time, through the setting of the third adjusting screw 522, the staff can adjust the distance between the support plates 521 on both sides by rotating the third adjusting screw 522, so that the support plates 521 on both sides can support and limit iron can covers of different sizes, so that the device can discharge iron can covers of different sizes.

[0043] One side of the support plate 521 is fixedly connected to a limit rod 523, and the surface of the limit rod 523 is slidably connected to the inside of the slide plate 520. Therefore, through the setting of the limit rod 523, the movement trajectory of the support plate 521 can be limited, thereby preventing the support plate 521 from rotating with the rotation of the third adjusting screw 522, thereby ensuring the smooth operation of the device. At the same time, a scale can be set on the limit rod 523, which is convenient for the staff to accurately adjust the distance of the support plate 521, thereby improving the convenience of using the device.

[0044] The output ends of the two electric push rods 508 are fixedly connected to the connecting plates 509, and the opposite sides of the two connecting plates 509 are fixedly connected to the racks 507. One end of the two rotating shafts 506 is fixedly connected to the gears 505. The surfaces of the two gears 505 are respectively meshed with the surfaces of the two racks 507, so that the power of the electric push rods 508 can be used to control the unloading of the iron can lids, reducing the installation of power equipment and improving the energy-saving effect of the device.

[0045] Specifically, the conveyor belt 2 transports the iron cans. As the conveyor belt 2 transports the iron cans, the iron cans enter between the two clamping plates 514 and are subsequently captured by the infrared sensor 525, thereby starting the electric push rod 508 and driving the clamping plate 512 to clamp the iron cans. At the same time, the start of the electric push rod 508 drives the rotating shaft 506 to rotate, thereby driving the push-pull plate 516 to rotate, thereby driving the position of the push-pull slot 517 to change, thereby causing the push-pull rod 518 originally located in the large arc groove of the push-pull slot 517 to now be located in the small arc groove of the push-pull slot 517, while the push-pull rod 518 originally located in the small arc groove of the push-pull slot 517 is now located in the small arc groove of the push-pull slot 517. The push-pull rod 518 in the shaped groove is now located in the large arc groove of the push-pull groove 517, so that the push-pull grooves 517 on both sides of the push-pull plate 516 pull or push the push-pull rod 518, so that the support plates 521 at the bottom on both sides move away from each other, and the two support plates 521 at the top move relatively, so that the two support plates 521 at the top are inserted between the second to last and the first to last iron can lids of the two blanking plates 501, and support the second to last iron can lid, and because the two support plates 521 at the bottom move away from each other, the first to last iron can lid is no longer supported. The support is provided, and then the last iron can lid falls along the surface of the two blanking plates 501 and then falls on the iron can, and then the two electric push rods 508 return to their original state and no longer clamp the iron can, so that the iron can is transported with the iron can lid to the gap of the rotating disk 303, and as the rotating disk 303 rotates, it is transported to the bottom of the iron can sealing mechanism for sealing. When it is necessary to process iron cans of different sizes, the staff can replace the corresponding rotating disk 303, and then rotate the first adjusting screw 503 according to the size of the iron can to adjust the distance between the two blanking plates 501, and Then, the third adjusting screw 522 is rotated to adjust the distance between the two side support plates 521 to ensure that the support plates 521 can smoothly support the iron can cover and the iron can cover can fall smoothly, and the second adjusting screw 513 is rotated to adjust the distance between the two clamping plates 514 to ensure that the iron can can smoothly pass through the two clamping plates 514, so that the device can process iron cans of different sizes, thereby improving the scope of application of the device, solving the problem that the existing equipment cannot load iron cans of various sizes, improving the versatility of the device, and improving the practicality of the device, which is worthy of promotion.

[0046] Working principle: The conveyor belt 2 transports the iron cans. As the conveyor belt 2 transports the iron cans, the iron cans enter between the two clamping plates 514 and are then captured by the infrared sensor 525, thereby starting the electric push rod 508 and driving the clamping plate 512 to clamp the iron can. At the same time, the start of the electric push rod 508 drives the rotating shaft 506 to rotate, thereby driving the push-pull plate 516 to rotate, thereby driving the position of the push-pull groove 517 to change, thereby causing the push-pull rod 518 originally located in the large arc groove of the push-pull groove 517 to now be located in the small arc groove of the push-pull groove 517, and the push-pull rod 518 originally located in the small arc groove of the push-pull groove 517 to now be located in the large arc groove of the push-pull groove 517, so that the push-pull grooves 517 on both sides of the push-pull plate 516 pull or Push, so that the support plates 521 located at the bottom on both sides move away from each other, and the two support plates 521 located above move relatively, so that the two upper support plates 521 are inserted between the second-to-last and the first-to-last iron can lids of the two blanking plates 501, and support the second-to-last iron can lid. Since the two lower support plates 521 move away from each other, they no longer support the first-to-last iron can lid, and the first-to-last iron can lid falls along the surfaces of the two blanking plates 501, and then falls on the iron can, and then the two electric push rods 508 return to their original state and no longer clamp the iron can, so that the iron can is transported to the gap of the rotating disk 303 with the iron can lid, and as the rotating disk 303 rotates, it is transported to the bottom of the iron can sealing mechanism for sealing.

[0047] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
