Description

Technical Field

[0001] This utility model relates to the field of automatic filling equipment technology, specifically to an automatic filling machine. Background Technology

[0002] Magnetic polishing equipment is a surface treatment device that uses a high-speed rotating magnetic field to drive magnetic needles to impact workpieces (such as stainless steel water cups) at high frequency. It can achieve thorough polishing without damaging the precision of the workpiece. Before polishing a stainless steel water cup, a certain amount of magnetic needles and water need to be filled into its inner liner. Existing filling methods are mostly manual. First, a certain amount of magnetic needles is measured and then introduced into the stainless steel water cup, followed by a certain amount of water.

[0003] The existing filling method is too cumbersome and requires a lot of manual labor, which is not only time-consuming and labor-intensive but also inefficient. The magnetic needles to be filled need to be weighed first, which is prone to human weighing errors, resulting in too many or too few magnetic needles, which affects the subsequent magnetic polishing. Utility Model Content

There are multiple receiving seats, which are evenly spaced along the ring track for placing workpieces. The drive unit is connected to the receiving seats and drives the receiving seats to rotate cyclically along the ring track, passing through the magnetic needle filling mechanism and the water filling mechanism in sequence. The magnetic needle filling mechanism is used to input a certain amount of magnetic needles into the workpieces on the receiving seats that it passes through, and the water filling mechanism is used to input a certain amount of water into the workpieces on the receiving seats that it passes through.

[0006] By adopting the above structure, the automatic filling machine of this utility model has the following advantages compared with the prior art: This invention features a circular track on a frame, with a rotating receiving seat on the track. The receiving seat drives the workpiece through a magnetic needle filling mechanism and a water filling mechanism in sequence. The magnetic needle filling mechanism and the water filling mechanism fill a fixed amount of magnetic needles and water into the workpiece, thereby achieving automatic quantitative filling of polishing material into the workpiece. This invention has a high degree of mechanization, saving time and effort while also being highly efficient.

[0007] Preferably, the receiving seat includes a base plate, the top of which has two symmetrically arranged clamping blocks forming a slot for the workpiece to be inserted; the bottom of the base plate is rotatably connected to two roller sets, which are symmetrically engaged on both sides of an annular track.

[0008] Preferably, the two side walls of the annular track are provided with recessed slots, and the roller assembly includes two rollers that are tactilely connected in the corresponding slots to prevent the base plate from falling off the annular track.

[0009] Preferably, the drive unit includes a conveyor belt and a drive motor. The conveyor belt is located inside the circular track and matches the shape of the circular track. The drive motor is connected to the conveyor belt for transmission. A radial protrusion is connected to the side wall of the base plate facing the conveyor belt. The radial protrusion has an elongated hole. Several screw groups corresponding to the receiving seats are connected to the conveyor belt. The free ends of the screw groups are movably connected to the elongated holes to prevent the receiving seats from getting stuck at the turns of the circular track.

[0010] Preferably, the magnetic needle filling mechanism includes a first support connected to the frame, a hopper on the first support, and a quantitative control component at the outlet of the hopper for controlling the opening and closing of the outlet and controlling the amount of magnetic needles output by the hopper in a single operation.

[0011] Preferably, the quantitative control component includes a horizontal slide rail, a first baffle, a first horizontal motor, and a metering cylinder; the horizontal slide rail is mounted on a first support, the first baffle is slidably connected to the horizontal slide rail, and its upper end face is in contact with the discharge port of the hopper; the first horizontal motor is mounted on the first support, and its output end is connected to the first baffle; the first baffle is provided with a through hole, and the metering cylinder is connected below the through hole; the first horizontal motor is used to drive the first baffle and the metering cylinder to move along the horizontal slide rail, and to make the through hole communicate with or be misaligned with the discharge port of the hopper; The bottom of the first baffle is connected to a mounting bracket, and a second horizontal motor is connected to the mounting bracket. A second baffle is connected to the output end of the second horizontal motor. The upper end face of the second baffle is in contact with the lower opening of the metering cylinder. The second horizontal motor is used to drive the second baffle to move horizontally, thereby opening or closing the lower opening of the metering cylinder.

[0012] Preferably, the mounting frame is provided with a receiving funnel below the second baffle for receiving magnetic needles dropped from the metering cylinder; a first detection sensor is provided on one side of the receiving funnel on the frame for detecting whether there is a workpiece at the station below the receiving funnel.

[0013] Preferably, the water filling mechanism includes a second bracket connected to the frame, a water inlet faucet connected to the second bracket, and a second detection sensor located on one side of the water inlet faucet on the frame.

[0014] Preferably, the water inlet includes a first water inlet and a second water inlet spaced apart along the workpiece conveying direction, with the water inlet rate of the second water inlet being lower than that of the first water inlet. The first and second water inlets perform water inlet operations separately, which can speed up the water inlet process, improve water inlet efficiency, and avoid affecting the conveyor belt speed due to excessive water inlet time. In addition, during water inlet, the first water inlet can quickly inject a portion of water into the workpiece, and then when the workpiece moves under the second water inlet, the second water inlet injects the remaining water at a slower rate to prevent water from splashing out of the workpiece and contaminating the equipment.

[0025] like Figures 1-7 As shown, this utility model discloses an automatic filling machine, including a frame 1, a circulating transmission mechanism 2 installed on one side of the frame 1, and a magnetic needle filling mechanism 3 and a water filling mechanism 4 connected to the frame 1. The circulating transmission mechanism 2 is used to drive the workpiece to pass through the magnetic needle filling mechanism 3 and the water filling mechanism 4 in sequence. The magnetic needle filling mechanism 3 is used to input a certain amount of magnetic needle into the workpiece on the receiving seat 22, and the water filling mechanism 4 is used to input a certain amount of water into the workpiece on the receiving seat 22.

[0026] The circulating transmission mechanism 2 includes an annular track 21, a receiving seat 22, and a driving unit 23. There are multiple receiving seats 22, which are evenly spaced along the annular track 21 and are used to place workpieces. An elastic element for buffering is also provided between two adjacent receiving seats 22. The driving unit 23 is connected to the receiving seat 22 and is used to drive the receiving seat 22 to rotate cyclically along the annular track 21.

[0027] This utility model sets up a ring track 21 on the frame 1, and a rotating accommodating seat 22 on the ring track 21. When the accommodating seat 22 drives the workpiece through the magnetic needle filling mechanism 3 and the water filling mechanism 4, it automatically fills a quantitative amount of magnetic needles and water, thereby realizing the automatic quantitative filling of polishing material in the workpiece. It has a high degree of mechanization, which not only saves time and labor, but also has high efficiency.

[0028] The receiving seat 22 includes a base plate 221. The top of the base plate 221 is provided with two symmetrically arranged clamping blocks 222. A slot for inserting the workpiece is formed between the two clamping blocks 222, which can prevent the workpiece from tipping over during the transfer process and causing the polishing material to spill out.

[0029] Two roller assemblies 223 are rotatably connected to the bottom of the base plate 221. The two roller assemblies 223 are symmetrically engaged on both sides of the annular track 21, allowing the base plate 221 to slide on the annular track 21. The two side walls of the annular track 21 are provided with recessed slots 211. The roller assembly 223 includes two rollers, which are rolled and connected in the corresponding slots 211 to prevent the base plate 221 from falling off the annular track 21.

[0030] The drive unit 23 includes a conveyor belt 231 and a drive motor 232. The conveyor belt 231 is located inside the annular track 21 and matches the shape of the annular track 21. The drive motor 232 is connected to the conveyor belt 231 for transmission. A radial protrusion 224 is connected to the side wall of the base plate 221 facing the conveyor belt 231. The radial protrusion 224 is provided with a radially extending elongated hole 225. Several screw groups 233 corresponding one-to-one with the receiving seat 22 are connected to the conveyor belt 231. The free end of the screw group 233 is movably connected to the elongated hole 225. While driving the receiving seat 22 to slide along the annular track 21, it prevents the receiving seat 22 from getting stuck at the bend of the annular track 21.

[0031] The magnetic needle filling mechanism 3 includes a first support 31 connected to the frame 1. A hopper 32 is provided on the first support 31. A quantitative control component 33 is provided at the outlet of the hopper 32 to control the opening and closing of the outlet of the hopper 32 and to control the amount of magnetic needles output by the hopper 32 in a single operation.

[0032] Specifically, the quantitative control component 33 includes a horizontal slide rail 331, a first baffle 332, a first horizontal motor 333, and a metering cylinder 334. The horizontal slide rail 331 is mounted on the first support 31, and the first baffle 332 is slidably connected to the horizontal slide rail 331, with its upper end face abutting against the discharge port of the hopper 32. The first horizontal motor 333 is mounted on the first support 31, and its output end is connected to the first baffle 332. The first baffle 332 has a through hole 3321, and the metering cylinder 334 is connected below the through hole 3321. The first horizontal motor 333 is used to drive the first baffle 332 and the metering cylinder 334 to move along the horizontal slide rail 331, and to make the through hole 3321 connected to or misaligned with the discharge port of the hopper 32.

[0033] The bottom of the first baffle 332 is connected to a mounting bracket 335, and a second horizontal motor 336 is connected to the mounting bracket 335. A second baffle 337 is connected to the output end of the second horizontal motor 336. The upper end face of the second baffle 337 is in contact with the lower end opening of the metering cylinder 334. The second horizontal motor 336 is used to drive the second baffle 337 to move horizontally, thereby opening or closing the lower end opening of the metering cylinder 334.

[0034] A receiving funnel 338 is provided on the mounting frame 335 below the second baffle 337 for receiving magnetic needles dropped from the metering cylinder 334; a first detection sensor 339 is provided on the frame 1 on one side of the receiving funnel 338 for detecting whether there is a workpiece at the station below the receiving funnel 338.

[0035] When the receiving seat 22 carries the workpiece past the receiving funnel 338, the first detection sensor 339 detects the presence of a workpiece and transmits the detection signal to the device controller. The controller controls the first horizontal motor 333 to drive the first baffle 332 and the metering cylinder 334 to move along the horizontal slide rail 331, and connects the through hole 3321 with the discharge port of the hopper 32. The magnetic needle in the hopper 32 fills the metering cylinder 334. Then, the first horizontal motor 333 drives the first baffle 332 and the metering cylinder 334 to reset. At this time, the hole 3321 is misaligned with the discharge port of the hopper 32, and the discharge port of the hopper 32 is closed. Then, the second horizontal motor 336 drives the second baffle 337 to move horizontally, opening the lower opening of the metering cylinder 334. The magnetic needle in the metering cylinder 334 passes through the receiving funnel 338 below and fills the workpiece (stainless steel water cup). Finally, the second horizontal motor 336 drives the second baffle 337 to reset, closing the lower opening of the metering cylinder 334, and repeating the next filling operation.

[0036] The water filling mechanism 4 includes a second bracket 41 connected to the frame 1, a water inlet faucet 42 connected to the second bracket 41, and a second detection sensor 43 located on one side of the water inlet faucet 42 on the frame 1. The second detection sensor 43 is electrically connected to the control switch of the water inlet faucet 42. The first detection sensor 339 and the second detection sensor 43 can be distance sensors, which can detect the approach of a metal workpiece to determine whether there is a workpiece on the receiving seat 22.

[0037] Water inlet faucet 42 includes a first water inlet faucet and a second water inlet faucet spaced apart along the workpiece conveying direction. The water inlet rate of the second water inlet faucet is less than that of the first water inlet faucet. The first and second water inlet faucets perform water inlet operations separately, which can speed up the water inlet progress, improve water inlet efficiency, and avoid affecting the conveying speed of the conveyor belt 231 due to excessive water inlet time. In addition, during water inlet, the first water inlet faucet can quickly inject a portion of water into the workpiece, and then when the workpiece moves under the second water inlet faucet, the second water inlet faucet injects the remaining water at a slower rate to prevent water from splashing out of the workpiece and contaminating the equipment.

Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
