Description

Technical Field

[0001] This utility model relates to the field of filling machine technology, and in particular to a filling machine oil negative pressure reflux recovery device. Background Technology

[0002] A negative pressure filling machine first creates negative pressure by evacuating the packaging container, and then fills the container with liquid. Its advantages include the ability to ignore manufacturing errors in the packaging container, and because it uses liquid level for quantitative filling, it achieves excellent consistency in the appearance of the filling level. It is best suited for glass bottle filling. During operation, the filling head assembly is inserted into the bottle by a lifting mechanism and seals the bottle opening. At this time, the vacuum system evacuates the bottle through a vacuum tank and vacuum tube, creating negative pressure inside. The filling liquid tank then fills the bottle through the filling tube and filling head assembly, achieving the filling purpose.

[0003] A search revealed Chinese Patent Publication No. CN210595196U, which discloses a negative pressure filling machine, including a frame, a liquid storage tank, and an electric cylinder. The frame includes an upper frame plate, a lower frame plate, and several connecting columns installed between the upper and lower frame plates. The liquid storage tank is located on one side of the upper surface of the upper frame plate. This invention uses a movable plate to connect with the vacuum container in a compression-sealing manner, ensuring the airtightness of the vacuum container. The valve mechanism, through the elastic deformation force generated by the elastic element, enables the entire slide to open and close the water outlet. At the same time, the water output and water output rate can be determined according to the deformation of the elastic element, making the overall device highly flexible in use.

[0004] The above-mentioned device has the following defects: when the filling machine is filling, the bottle body and bottom itself will generate a large pressure, and it is difficult to position the bottle, which will cause the bottle to deviate during filling and cause leakage of liquid. To solve the above problems, a filling machine oil negative pressure reflux recovery device is proposed. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a negative pressure reflux recovery device for filling machines, which aims to improve the problem in the prior art where the bottle body and bottom themselves generate large pressure during filling, and it is difficult to position the bottle, resulting in the bottle body deviating during filling and causing errors and liquid leakage.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a filling machine oil negative pressure reflux recovery device, comprising an oil injection frame, a hydraulic cylinder fixedly connected to the bottom outer wall of the oil injection frame, an operating disc rotatably connected to the output end of the hydraulic cylinder via a bearing, the bottom outer wall of the operating disc fixedly connected to the top outer wall of the negative pressure chamber via a coupling, an adjustment mechanism provided on the top outer wall of the operating disc for oil recovery, an auxiliary mechanism provided on the adjustment mechanism for maintaining the arc-shaped clamping plate, the adjustment mechanism comprising an oil discharge cylinder, the oil discharge cylinder fixedly connected to the top inner wall of the operating disc, a support frame fixedly connected to the top of the oil discharge cylinder, sliding grooves provided on both sides of the inner walls of the support frame, sliding frames slidably connected to both sides of the inner walls of the sliding grooves, arc-shaped clamping plates slidably connected to both sides of the inner walls of the sliding frames, a first spring engaged on the bottom outer wall of the arc-shaped clamping plate, and a second spring fixedly connected to one side of the outer wall of the sliding frame.

[0007] As a further description of the above technical solution: the auxiliary mechanism includes an arc-shaped groove, which is formed on the top outer wall of the arc-shaped clamping plate, and threaded grooves are formed on both inner walls of the sliding frame, with a threaded rod threadedly connected to the inner ring of the threaded groove.

[0008] As a further description of the above technical solution: a recovery pipe is fixedly connected to one side of the outer wall of the negative pressure chamber, the oil drain cylinder penetrates the bottom inner wall of the negative pressure chamber, the bottom end of the oil drain cylinder is connected to the recovery pipe, and the oil drain cylinder penetrates the top outer wall of the support frame.

[0009] As a further description of the above technical solution: the end of the first spring away from the arc-shaped clamp is fixedly connected to the inner wall of one side of the sliding frame, and the end of the second spring away from the sliding frame is fixedly connected to the inner wall of one side of the support frame.

[0010] As a further description of the above technical solution: the end of the recovery pipe away from the negative pressure chamber is fixedly connected to the outer wall of one side of the oil injection frame, and the recovery pipe is connected to the negative pressure chamber.

[0011] As a further description of the above technical solution: a wear-resistant pad is fixedly connected to the bottom inner wall of the arc-shaped clamp.

[0012] As a further description of the above technical solution: an adjusting disc is fixedly connected to the end of the threaded rod away from the threaded groove, and a groove is provided on the outer side wall of the adjusting disc.

[0013] As a further description of the above technical solution: an indicator mark is provided on one side of the outer wall of the adjustment disc.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by setting up a support frame, an oil drain tank, an arc-shaped clamping plate and other structures, the bottle is flexibly clamped and limited, which improves the situation where the bottle body and bottom itself generate large pressure during filling and it is difficult to position the bottle, resulting in the bottle body deviating and causing errors and liquid leakage during filling. At the same time, the excess leaked oil after filling is recycled and returned to the inside of the oil filling machine frame, reducing the problem of oil dripping to the outside and causing waste.

[0016] 2. In this utility model, by setting up structures such as threaded grooves, threaded rods, and adjusting discs, the arc-shaped clamping plate can be easily disassembled, replaced, and maintained. This improves the problem that arc-shaped clamping plates are prone to wear and aging after long-term use, which leads to a decrease in clamping and limiting performance and makes it difficult for personnel to replace and maintain them in a timely manner, thus affecting work efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-3This utility model provides an embodiment of an oil negative pressure reflux recovery device for a filling machine, including an oil injection frame 1. A hydraulic cylinder 2 is fixedly connected to the bottom outer wall of the oil injection frame 1. The output end of the hydraulic cylinder 2 is rotatably connected to an operating plate 3 via a bearing. The bottom outer wall of the operating plate 3 is fixedly connected to the top outer wall of a negative pressure chamber 4 via a coupling. By setting the negative pressure chamber 4, a vacuum negative pressure is applied to the inside of the recovery pipe 58. The above mechanism is existing technology and therefore will not be described in detail. An adjustment mechanism 5 is provided on the top outer wall of the operating plate 3 for oil recovery. An auxiliary mechanism 6 is provided on the adjustment mechanism 5 to maintain the arc-shaped clamp 55. The adjustment mechanism 5 includes an oil discharge cylinder 51, which is used to collect and recover oil. The oil discharge cylinder 51 is fixedly connected to the operating plate 3. The top inner wall of the oil discharge cylinder 51 is fixedly connected to a support frame 52. The inner walls of both sides of the support frame 52 are provided with sliding grooves 53. The inner walls of both sides of the sliding grooves 53 are slidably connected to sliding frames 54. The inner walls of both sides of the sliding frames 54 are slidably connected to arc-shaped clamps 55. By setting the arc-shaped clamps 55, different bottles to be filled are clamped and limited, reducing the error caused by the deviating of the bottle during filling and the leakage of liquid. The bottom outer wall of the arc-shaped clamps 55 is clamped with a first spring 56. The end of the recovery pipe 58 away from the negative pressure box 4 is fixedly connected to the outer wall of one side of the oil filling machine frame 1. The recovery pipe 58 is connected to the negative pressure box 4. By setting the recovery pipe 58, the oil collected by the oil discharge cylinder 51 is returned to the inside of the oil filling machine frame 1 through negative pressure rewashing. The bottom inner wall of the arc-shaped clamps 55 is fixedly connected with a wear-resistant pad.

[0025] Reference Figures 2-3 A recovery pipe 58 is fixedly connected to one side of the outer wall of the negative pressure chamber 4. The oil drain cylinder 51 penetrates the bottom inner wall of the negative pressure chamber 4. The bottom end of the oil drain cylinder 51 is connected to the recovery pipe 58. The oil drain cylinder 51 penetrates the top outer wall of the support frame 52. A second spring 57 is fixedly connected to one side of the outer wall of the sliding frame 54. The end of the first spring 56 away from the arc-shaped clamp 55 is fixedly connected to one side of the inner wall of the sliding frame 54. By setting the first spring 56 to continuously push the arc-shaped clamp 55 upward, a certain flexible pushing force is generated, which reduces the problem of breakage caused by the large pressure generated by the bottle body and bottle bottom when the filling machine nozzle is pressed down to fill. The end of the second spring 57 away from the sliding frame 54 is fixedly connected to one side of the inner wall of the support frame 52.

[0026] Reference Figures 3-4The auxiliary mechanism 6 includes an arc-shaped groove 61, which is formed on the top outer wall of the arc-shaped clamping plate 55. The arc-shaped groove 61 allows the bottle to be inserted directly into the surface of the arc-shaped clamping plate 55, causing the arc-shaped clamping plate 55 to be squeezed and unfolded to the sides to clamp and limit the bottle. The inner walls of both sides of the sliding frame 54 are provided with threaded grooves 62. The inner ring of the threaded groove 62 is threadedly connected to a threaded rod 63. The arc-shaped clamping plate 55 is limited to move upward within the threaded rod 63. The end of the threaded rod 63 away from the threaded groove 62 is fixedly connected to an adjusting plate 64. The adjusting plate 64 facilitates operation. The outer wall of the side of the adjusting plate 64 is provided with a groove, and an indicator is provided on one side of the outer wall of the adjusting plate 64 to indicate the operation method.

[0027] Working principle: By inserting the bottle to be filled between the two arc-shaped clamps 55, the arc-shaped clamps 55 expand outward and compress the second spring 57. The second spring 57 continuously exerts a pushing force on the arc-shaped clamps 55, thereby clamping and limiting the outer wall of the bottle to be filled. Then, the hydraulic cylinder 2 is activated to lower the oil injection frame 1, so that the oil nozzle at the bottom of the oil injection frame 1 presses the top of the bottle to be filled. When pressing the bottle, the arc-shaped clamps 55 move, and the arc-shaped clamps 55 compress the first spring 56, preventing damage or leakage to the bottle due to excessive or insufficient pressure. At the same time, after the equipment is used up, the threaded rod 63 is rotated by rotating the adjusting plate 64. The threaded rod 63 rotates and disengages from the threaded groove 62, so that the arc-shaped clamps 55 are separated from the sliding frame 54 for maintenance and replacement.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
