Description

[0002] Cutting fluid is a liquid used in the cutting process of metal, stone, glass and other materials, and has the functions of cooling, lubrication and chip removal. It is mainly composed of base oil, emulsifier, rust inhibitor, extreme pressure additive, defoamer and other ingredients.

[0003] Cutting fluids can be divided into water-based cutting fluids, oil-based cutting fluids and synthetic cutting fluids. Among them, oil-based cutting fluids are mainly composed of mineral oil or synthetic oil, have a certain viscosity and good lubricity.

[0004] During the production process, cutting liquid needs to be injected into the bottle body. After each injection of cutting liquid by the existing quantitative injection device for cutting liquid production, a lot of cutting liquid is likely to remain in the injection hose. During the next injection, this part of the cutting liquid is likely to mix with the air and enter the bottle body, which will cause insufficient injection accuracy in the bottle body.

[0027] 4. When the scraper moves along the inner wall of the tapered sleeve, the tooth plate contacts the rubber rack.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0041] like Figure 1-Figure 10 As shown, a quantitative injection device for cutting fluid production provided by the present invention comprises a base 1, the base 1 is fixedly connected to a support table 2, the support table 2 is rotatably connected to a placement table 11, a driving mechanism capable of driving the placement table 11 to rotate intermittently is arranged at the bottom of the support table 2, and a capping machine 12 for screwing a cap on a bottle body is arranged on one side of the support table 2;

[0042] A positioning mechanism 3 for positioning the bottle body is arranged at the center of the support platform 2, the base 1 is fixedly connected to a support frame 13, a water tank 14 and a driving rod 15 are fixedly arranged on the end surface of the support frame 13, a measuring cylinder 16 is fixedly connected to the telescopic end of the driving rod 15, a hydraulic mechanism 4 is arranged between the measuring cylinder 16 and the water tank 14, and the hydraulic mechanism 4 can drive the cutting fluid in the water tank 14 and the measuring cylinder 16 to circulate;

[0043] The bottom surface of the measuring cylinder 16 is connected with a connecting sleeve 10, and a conical sleeve 18 is sleeved outside the connecting sleeve 10, and the conical sleeve 18 is fixedly connected to the bottom of the measuring cylinder 16. A hydraulic valve 9 is arranged in the connecting sleeve 10, and a discharging mechanism 5 for pushing liquid outward is arranged in the measuring cylinder 16. A telescopic limiting rod 17 for vertically positioning the discharging mechanism 5 is fixedly arranged on the top surface of the measuring cylinder 16;

[0044] A sealing mechanism 6 is provided at the discharge hole of the conical sleeve 18, and a scraping mechanism 7 is provided inside the conical sleeve 18. The scraping mechanism 7 can scrape along the inner wall of the conical sleeve 18. The scraping mechanism 7 is connected to a blowing mechanism 8, and the blowing mechanism 8 can discharge the cutting fluid on the inner wall of the conical sleeve 18 downwards together with the scraping mechanism 7.

[0045] In this embodiment, the hydraulic mechanism 4 is started before use, and the hydraulic mechanism 4 drives the cutting liquid between the water tank 14 and the measuring cylinder 16 to circulate, which increases the fluidity of the cutting liquid on the one hand, and makes the hydraulic mechanism 4 and the sealing mechanism 6 filled with the cutting liquid before the injection starts, thereby preventing the hydraulic mechanism 4 and the sealing mechanism 6 from mixing with too much air when the injection starts;

[0046] When injecting materials, first close one end of the measuring cylinder 16 to increase the hydraulic pressure of the hydraulic mechanism 4. The hydraulic pressure directly acts on the measuring cylinder 16 to further ensure that the measuring cylinder 16 is filled with cutting liquid. The cutting liquid pushes the discharging mechanism 5 to move to a predetermined position (the volume in the measuring cylinder 16 can be changed by adjusting the telescopic limit rod 17, thereby determining the liquid output of a single discharge in the measuring cylinder 16), and close the other end of the measuring cylinder 16;

[0047] All bottles are placed in the respective placement cylinders on the placement table 11, and then the driving mechanism drives the placement table 11 to rotate, and the placement table 11 drives each bottle to move to the lower side of the positioning mechanism 3 in turn, and the bottle is fixed by the positioning mechanism 3, and then the driving rod 15 drives the measuring cylinder 16 to move downward, and the measuring cylinder 16 drives the conical sleeve 18 to move downward, and at this time, the sealing mechanism 6 releases the sealing of the conical sleeve 18;

[0048] Then the discharging mechanism 5 pushes the liquid outside the vector cylinder 16, and the cutting liquid flows downward through the connecting sleeve 10. Under the guidance of the tapered sleeve 18, the cutting liquid enters the bottle body;

[0049] During this process, the scraping mechanism 7 can scrape along the inner wall of the tapered sleeve 18, and the blowing mechanism 8 can discharge the cutting liquid on the inner wall of the tapered sleeve 18 downwards together with the scraping mechanism 7, thereby discharging the cutting liquid remaining on the inner wall of the tapered sleeve 18, further improving the injection accuracy of the cutting liquid during injection;

[0050] Afterwards, the bottle cap is placed on the bottle body by a conveying mechanism or manually, and the bottle body is capped by a capping machine 12 .

[0051] like Figure 2 As shown, it is a quantitative injection device for cutting fluid production provided by the present invention, wherein the hydraulic mechanism 4 includes a hydraulic pump 41, a conduit 42 and a solenoid valve 43;

[0052] Solenoid valves 43 are disposed on both side end surfaces of the measuring cylinder 16 . A conduit 42 is connected between the solenoid valve 43 and the water tank 14 . A hydraulic pump 41 is disposed between one of the conduits 42 and the water tank 14 .

[0053] In this embodiment, the hydraulic pump 41 is started, and the hydraulic pump 41 drives the cutting fluid in the water tank 14 to circulate between the water tank 14 and the measuring cylinder 16, thereby increasing the fluidity of the cutting fluid and bringing the remaining cutting fluid in the conduit 42 and the measuring cylinder 16 into the water tank 14 for flow;

[0054] When injecting liquid, first close the solenoid valve 43 on one side of the measuring cylinder 16. At this time, the pump pressure of the hydraulic pump 41 acts on the measuring cylinder 16, thereby filling the measuring cylinder 16 with cutting liquid. At this time, close the solenoid valve 43 on the other side of the measuring cylinder 16, thereby sealing the measuring cylinder 16. Then, start the discharging mechanism 5 to discharge the cutting liquid into the connecting sleeve 10 through the hydraulic valve 9. By filling and sealing the measuring cylinder 16, it can be prevented that the cutting liquid in the conduit 42 falls into the bottle body excessively under the action of gravity during the injection process, and at the same time, it can be prevented that air is mixed into the measuring cylinder 16.

[0055] like Figure 3 As shown, a quantitative injection device for cutting fluid production provided by the present invention is provided, the discharging mechanism 5 includes a No. 1 sealing plate 51 and a telescopic push rod 52, the inner wall of the measuring cylinder 16 slides vertically and is sealedly connected to the No. 1 sealing plate 51, the guide holes of the two solenoid valves 43 are both arranged at the lower part of the No. 1 sealing plate 51, the top surface of the measuring cylinder 16 is fixedly connected to the telescopic push rod 52, and the telescopic ends of the telescopic push rod 52 and the telescopic limit rod 17 are both facing the No. 1 sealing plate 51.

[0056] In this embodiment, when the solenoid valve 43 on one side of the measuring cylinder 16 is closed, the cutting fluid pushes the No. 1 sealing plate 51 upward under the pressure of the hydraulic pump 41 until the No. 1 sealing plate 51 abuts against the telescopic limit rod 17, and the area between the No. 1 sealing plate 51 and the bottom surface of the measuring cylinder 16 is filled with cutting fluid. At this time, the solenoid valve 43 at the other end of the measuring cylinder 16 is closed, so that the cutting fluid is quantitatively stored in the measuring cylinder 16.

[0057] By controlling the telescopic length of the telescopic limit rod 17, the maximum height of the No. 1 sealing plate 51 can be controlled, thereby adjusting the actual volume of the measuring cylinder 16 and controlling the amount of liquid injected into the bottle body at one time.

[0058] like Figure 5 and Figure 6 As shown, a quantitative injection device for cutting fluid production provided by the present invention is provided, wherein the scraping mechanism 7 comprises a rotating sleeve 71, a scraper 72 and a driving assembly 73;

[0059] The outer wall of the connecting sleeve 10 is rotatably connected with a rotating sleeve 71, the bottom surface of the scraper 72 is slidably connected with the scraper 72, a second spring 75 is connected between the scraper 72 and the rotating sleeve 71, and the bottom surface of the measuring cylinder 16 is connected with a driving assembly 73 that can drive the rotating sleeve 71 to rotate;

[0060] The driving assembly 73 includes a motor 731, a driving wheel 732 and a ring gear 733. The motor 731 is fixedly connected to the bottom surface of the measuring cylinder 16. The output shaft of the motor 731 passes through the side wall of the tapered sleeve 18, and the output shaft of the motor 731 is fixedly connected to the driving wheel 732. The upper end surface of the rotating sleeve 71 is annularly provided with a ring gear 733, and the driving wheel 732 is meshed with the ring gear 733.

[0061] In this embodiment, the motor 731 is started, and the motor 731 drives the rotating sleeve 71 to rotate through the engagement of the driving wheel 732 and the ring gear 733. The rotating sleeve 71 drives all scrapers 72 to scrape the cutting liquid on the inner wall of the conical sleeve 18 to prevent the cutting liquid from sticking to the inner wall of the conical sleeve 18.

[0062] like Figure 7 As shown, a quantitative injection device for cutting fluid production provided by the present invention, the scraper mechanism 7 also includes a transmission assembly 74, the transmission assembly 74 includes a tooth plate 741 and a rubber rack 742, the end face of the rotating sleeve 71 that fits the inner wall of the conical sleeve 18 is provided with a tooth plate 741, the inner wall of the conical sleeve 18 is annularly embedded with multiple sections of rubber racks 742, and the tooth plate 741 and the rubber rack 742 are arranged at the same height.

[0063] In this embodiment, when the scraper 72 moves along the inner wall of the conical sleeve 18, the tooth plate 741 contacts the rubber rack 742. Then, as the scraper 72 moves, under the elastic force of the No. 2 spring 75, the tooth plate 741 drives the scraper 72 to vibrate, thereby vibrating away the cutting fluid remaining on the scraper 72.

[0064] An air pump 81 is fixedly connected to the outer wall of the measuring cylinder 16, and a cover plate 82 is fixedly connected to the outer wall of the connecting sleeve 10. The cover plate 82 covers the rotating sleeve 71, and the cover plate 82 is rotatably connected to the rotating sleeve 71. A closed cavity is formed between the rotating sleeve 71, the cover plate 82 and the connecting sleeve 10, and the closed cavity is communicated with the air pump 81 through a hose. A plastic tube is connected between the scraper 72 and the rotating sleeve 71, and one end of the plastic tube is communicated with the closed cavity. The scraper 72 is provided with a plurality of air holes 83 obliquely downward along the length direction.

[0065] In this embodiment, air is injected into the closed cavity through an air pump 81, and then the air flow is passed into the scraper 72 through a plastic tube. The scraper 72 scrapes the cutting liquid on the inner wall of the conical sleeve 18, and the scraped cutting liquid is further accelerated and blown into the bottle body through the air flow;

[0066] like Figure 4 As shown, it is a quantitative injection device for cutting fluid production provided by the present invention, the sealing mechanism 6 includes a guide rod 61, a No. 1 spring 62 and a No. 2 sealing plate 63;

The bottom surface of the sealing plate 63 is an inclined surface, and the bottom surface of the sealing plate 63 can abut against the positioning mechanism 3.

[0068] In this embodiment, when the conical sleeve 18 drives the sealing plate 63 to move downward, the sealing plate 63 abuts against the positioning mechanism 3. Under the action of the thrust, the sealing plate 63 moves horizontally and pushes the No. 1 spring 62 to compress. At this time, the sealing plate 63 releases the seal on the discharge hole of the conical sleeve 18.

[0069] like Fig. 9 and Fig.10 As shown, it is a quantitative injection device for cutting fluid production provided by the present invention, the positioning mechanism 3 includes a No. 1 electric rod 31, a fixing frame 32, a No. 2 electric rod 33, a telescopic clamp 34 and a convex rubber ring 35;

[0071] In this embodiment, the No. 1 electric rod 31 descends in height so that the two telescopic clamps 34 are located on both sides of the bottle mouth. At this time, the two No. 2 electric rods 33 are started and extended at the same time, and the two No. 2 electric rods 33 drive the telescopic clamps 34 connected thereto to approach each other. The bottom of the telescopic clamps 34 fixes the bottle body, and at the same time the convex rubber ring 35 wraps the side wall of the bottle mouth to prevent the cutting fluid from contaminating the bottle mouth when discharging. Furthermore, the vertical telescopic end of the telescopic clamp 34 can abut against the sealing plate 63 to prevent the sealing plate 63 from directly applying pressure to the bottle body when moving downward.
