Description

Technical Field

[0001] The utility model relates to the technical field of filling equipment, in particular to a quantitative paint filling head. Background Art

[0002] Filling refers to the process of filling liquid or gas products in a predetermined amount, speed and accuracy using specific filling equipment during the production process. This filling method is usually used in the packaging industry, such as beverages, food, medicine, cosmetics, etc. In the filling of paint, it is necessary to control the filling speed and volume to avoid bubbles or overflow, but the current filling head cannot accurately control the volume filled into the paint bucket.

[0003] The Chinese utility model patent with the name of "a quantitative filling head" and the publication number CN219771747U has been published. The patent includes a measuring cylinder with a buffer cylinder at the bottom. The buffer cylinder is connected to the measuring cylinder through a feed pipe on its side to ensure the continuous supply of adhesive. A filling nozzle is provided at the bottom of the buffer cylinder to fill the adhesive into the target container. The device can always keep the buffer cylinder full of adhesive during the filling process, avoiding the influence of residual adhesive inside the device on the filling amount, thereby improving the filling accuracy. However, when filling smaller containers, the filling head that is always full cannot stop filling in time after quantitative input of the filling container. Utility Model Content

[0025] Example

[0026] Please refer to Figure 1-Figure 4 The utility model provides a paint quantitative filling head, including a first material storage barrel 1, a second material storage barrel 2, a blocking structure, and a pull rod 12.

[0027] The first storage barrel 1 is cylindrical, with a discharge port at the bottom, and a thread is provided on the outer wall of the top opening of the first storage barrel 1. The second storage barrel 2 is cylindrical, with a feed port at the top, and a thread is provided on the inner wall of the bottom opening of the second storage barrel 2. The first storage barrel 1 and the second storage barrel 2 are matched by threads, and the openings of the two are symmetrically oriented to each other to form a closed space.

[0028] When it is necessary to adjust the size of the space formed by the first storage barrel 1 and the second storage barrel 2 to fill different amounts of paint, the first storage barrel 1 or the second storage barrel 2 is rotated. Through the rotation of the thread, the first storage barrel 1 moves vertically relative to the second storage barrel 2, increasing or decreasing the capacity of the space formed inside the first storage barrel 1 and the second storage barrel 2.

[0029] A blocking structure is slidably arranged in the internal chute of the first storage barrel and the second storage barrel, and the blocking structure slides to block the feed port and the discharge port. When the first storage barrel or the second storage barrel rotates, the blocking structure is a telescopic structure, and the relative vertical distance between the chute of the first storage barrel and the second storage barrel changes, and the vertical length distance of the blocking structure changes synchronously.

[0030] A stepped chute is provided inside the other end of the first storage barrel 1 and the second storage barrel 2 away from the opening, and the chute shape of each step is a waist hole shape, and the chute mouth is open to the cylinder. In the stepped chute of the first storage barrel 1, the size of the chute above the step is smaller than the chute below the step, and the smaller chute vertically penetrates the discharge port of the first storage barrel 1. In the stepped chute of the second storage barrel 2, the size of the chute above the step is larger than the chute below the step, and the smaller chute vertically penetrates the discharge port of the second storage barrel 2. The feed port of the storage barrel 2, the upper and lower ends of the sealing structure slide in the stepped chutes of the first storage barrel 1 and the second storage barrel 2, and can completely block the chute space when sliding into the smallest chute. The shape of the waist-shaped hole in the chute of the first storage barrel 1 limits the free rotation of the sealing mechanism, so that during filling, the sealing mechanism only slides vertically in the chute. The pull rod 12 is fixed at the top of the sealing structure and passes through the circular hole at the top of the second storage barrel 2. A warning strip is sprayed on the outer wall of the pull rod 12 for people to observe.

[0031] Before filling, there is no paint inside the device, and the bottom of the sealing structure slides into the smallest slide groove of the first storage barrel 1 due to gravity, blocking the discharge port of the first storage barrel 1. Because the top of the sealing structure has a certain length, the top of the sealing structure slides downward into the larger slide groove of the stepped slide groove of the second storage barrel 2, allowing the feed port of the second storage barrel 2 to flow with the inside of the device.

[0032] When filling, the paint enters the device from the feed port of the second storage barrel 2. The blocking structure has buoyancy, but when the paint is not close to the top of the blocking structure, the gravity of the blocking mechanism is greater than its buoyancy, and the blocking mechanism will not slide in the stepped chute, and the discharge port of the first storage barrel 1 is still blocked; when the paint contacts the top of the blocking structure, the gravity of the blocking mechanism is less than its buoyancy, and the blocking mechanism slides vertically upward in the stepped chute, and the top of the blocking structure slides into the smallest chute of the second storage barrel 2, blocking the feed port of the second storage barrel 2, but at this time, the paint cannot continue to enter the device, and the blocking structure stops sliding as soon as it enters the smallest chute of the second storage barrel 2, so the bottom of the blocking structure has not completely slid out of the smallest chute of the first storage barrel 1, and the discharge port of the first storage barrel 1 is still blocked. At this time, the paint inside the device is quantitatively filled into the device and will not flow out.

[0033] When filling to the outside, after the paint is quantitatively stored inside the device, the pull rod 12 moves up a specified distance through the upward movement of the blocking structure, exposing the warning strip on the outer wall of the pull rod 12, so that outsiders can observe that the filling inside the device is complete; then the pull rod 12 is pulled, and the pull rod 12 slides in the circular hole sliding on the second storage barrel 2, driving the blocking structure to move vertically upward, so that the bottom slide of the blocking structure slides into the minimum slide of the first storage barrel 1, allowing the discharge port of the first storage barrel 1 to flow, and the quantitative paint inside the device is filled into the external paint bucket.

[0034] Furthermore, a paint quantitative filling head also includes a pump pipe 3 and a filling pipe 4.

[0035] The pump pipe 3 is threadedly installed at the feed port on the top of the second storage barrel 2 to pump the paint into the device. The injection pipe 4 is fixedly installed at the discharge port at the bottom of the first storage barrel 1 to guide the paint into the external paint bucket. The injection pipe 4 has a small diameter and can be extended into a paint bucket with a narrower diameter. It can also reduce the flow rate of the paint from the device into the paint bucket and reduce the generation of bubbles in the paint bucket.

[0036] Furthermore, the blocking structure includes a first cavity block 5 , a first support rod 6 , a first scraper 7 , a second support rod 8 , a second scraper 9 , and a second cavity block 10 .

[0037] The first cavity block 5 slides in the stepped groove inside the second storage barrel 2. There is a cavity inside the first cavity block 5 to generate buoyancy. The shape of the first cavity block 5 is matched with the waist hole shape, so that it is completely matched with the minimum groove shape inside the second storage barrel 2, and the feed port of the second storage barrel 2 can be blocked. The bottom of the first cavity block 5 is fixedly connected with a first support rod 6. The hollow inner wall inside the first support rod 6 is provided with a thread, which is threadedly connected to the outer wall of the second support rod 8. When the first storage barrel 1 and the second storage barrel 2 are aligned and threadedly connected, the first support rod 6 and the second support rod 8 are also aligned and threadedly connected.

[0038] A first scraper 7 is fixed to the middle end of the first support rod 6, and the circular outer edge of the first scraper 7 fits with the inner wall of the second storage barrel 2. There is at least one through hole on the plate surface of the first scraper 7, which facilitates the paint to pass through the first scraper 7 and circulate inside the device; the first support rod 6 and the second support rod 8 are coaxial, the first support rod 6 is vertically located in the second storage barrel 2, and the second support rod 8 is vertically located in the first storage barrel 1. A second scraper 9 is fixed to the middle end of the second support rod 8, and the circular outer edge of the second scraper 9 fits with the inner wall of the first storage barrel 1, and there is at least one through hole on the plate surface of the second scraper 9. A second cavity block 10 is fixedly connected to the bottom of the second support rod 8, and the second cavity block 10 slides in the stepped chute inside the first storage barrel 1. There is a cavity inside the second cavity block 10 to generate buoyancy. The shape of the second cavity block 10 is a waist hole shape, which is completely matched with the shape of the minimum chute inside the first storage barrel 1, and can block the discharge port of the first storage barrel 1.

[0039] During filling, the paint covers the second cavity block 10, but the gravity of the blocking structure cannot slide due to the buoyancy of the second cavity block 10. The paint contacts the first cavity block 5. The common buoyancy of the first cavity block 5 and the second cavity block 10 exceeds the gravity of the blocking mechanism. The blocking structure begins to slide in the stepped chute, thereby achieving blocking and circulation of the inlet and outlet.

[0040] After filling is completed, the pull rod 12 is released. As the paint inside the device basically flows out, the sealing structure slides down inside the first storage barrel 1 and the second storage barrel 2 under gravity. The circular outer edges of the first scraper 7 and the second scraper 9 scrape off excess paint remaining on the inner walls of the first storage barrel 1 and the second storage barrel 2, and continue to scrape the paint into the discharge port, while maintaining the accuracy of the internal capacity of the device.

[0041] When adjusting the capacity of the device, the first storage barrel 1 or the second storage barrel 2 is rotated to change the size of the space inside the device, and the stepped chute inside the first storage barrel 1 and the second storage barrel 2 is limited by the waist hole shape, and when rotating, it will drive the first cavity block 5 or the second cavity block 10 to rotate in the same direction. The first cavity block 5 and the second cavity block 10 are connected together by the threads of the first support rod 6 and the second support rod 8, so that when the relative distance between the first storage barrel 1 and the second storage barrel 2 changes, the first cavity block 5 and the second cavity block 10 will also change the relative vertical distance through the threads. Therefore, when the first storage barrel 1 and the second storage barrel 2 rotate relative to each other, when the relative vertical distance of the stepped chute inside the two changes, the first cavity block 5 and the second cavity block 10 will also change the same vertical distance, ensuring that when filling devices of different capacities, the blocking structure can vertically displace the same distance to achieve quantitative filling of the device.

[0042] Please refer to Figure 5 In some embodiments, a paint quantitative filling head further includes a scale plate 11.

[0043] The scale plate 11 is fixedly mounted on the outer wall of the second storage barrel 2. The scale plate 11 has scale lines extended by spraying paint, and the scale lines extend to the outer wall of the first storage barrel 1. A part of the extended scale lines on the outer wall of the first storage barrel 1 will be covered by the second storage barrel 2 when adjusting the capacity. When adjusting the capacity of the device and reading the capacity, the scale reading of the scale plate 11 on the second storage barrel 2 and the scale mark exposed on the outer wall of the first storage barrel 1 are added to obtain the capacity value.

[0044] So far, various embodiments of the present invention have been described in detail.
