Description

Technical Field

[0001] The utility model relates to the technical field of latex production, in particular to an automatic weighing storage tank. Background Art

[0002] Latex is formerly known as latex. It is a general term for colloidal latex formed by polymer particles dispersed in water. Usually, the water dispersion system of rubber particles is called latex; the water dispersion system of resin particles is called latex. It can be directly used as surface coating, making films and adhesives, etc., and can be processed into raw rubber and latex products (such as sponges, gloves, balloons, condoms, medical hoses, etc.), which are widely used in daily life.

[0003] A Chinese patent with the publication number of CN210311818U discloses a storage tank for latex production, which relates to the technical field of latex production equipment, and specifically comprises a tank body, wherein a support bracket is fixedly connected to the lower surface of the tank body, and a motor is mounted on the upper surface of the tank body through a motor mounting frame. When the utility model is in use, water is first introduced into the jacket through a water inlet pipe, and the water in the jacket is heated by a heating pipe, so that the latex in the tank body can be evenly heated by heat exchange, thereby improving the fluidity of the latex, and then the rotation of the motor drives the rotation of the threaded rod, and the rotation of the threaded rod drives the pressing plate to move downward, and the sliding rod acts as a limit to prevent the pressing plate from rotating, so that the latex in the tank body can be squeezed out by the discharge pipe, thereby improving the discharge rate of the latex, thereby facilitating the use of latex production, and at the same time, when the pressure plate moves downward, the latex stuck on the inner side of the tank body can be scraped off, so that the cleaning personnel can clean the tank body and reduce the labor intensity of the cleaning personnel.

[0004] However, in the above-mentioned technology, the patent cleans the sticky latex remaining in the tank body by moving the threaded rod scraper. The cleaning relies on the friction between the tube and the inner wall of the tank. However, after the scraper has been running for a period of time, the friction between the scraper and the inner wall causes the scraper to wear, and the distance between the scraper and the inner wall gradually increases, resulting in a decrease in the cleaning effect. Utility Model Content

[0005] The utility model aims to provide an automatic weighing storage tank in view of the problems existing in the background technology.

[0006] The technical solution of the utility model is: an automatic weighing storage tank, comprising a storage tank body, the storage tank body is connected with supporting feet distributed in a circumference, a weighing sensor is arranged at the bottom of the supporting feet, the weighing sensor is electrically connected to a display, a scraper is arranged in the storage tank body, the scraper is arranged on a cleaning mechanism, the cleaning mechanism can drive the scraper to reciprocate along the axis of the storage tank body, and a feeding pipe and a discharging pipe are respectively arranged on both sides of the storage tank body;

[0007] The cleaning mechanism includes a cleaning component and an expansion component. The cleaning component is arranged at the axis of the storage tank body and drives the scraper to move back and forth. The expansion component is arranged inside the scraper, and the expansion component drives the outer peripheral wall of the scraper to expand and slide in connection with the inner wall of the storage tank body.

[0008] Preferably, the cleaning assembly includes a motor, a threaded rod, and a guide assembly for limiting the scraper to rotate with the threaded rod. The motor is connected to the top of the tank body, and the output end of the motor passes through the tank body and is connected to the threaded rod. A threaded hole matching the threaded rod is provided on the scraper, and the threaded rod passes through the threaded hole and is rotatably connected to the tank body. A guide assembly is provided on the outer peripheral wall of the scraper.

[0009] Preferably, the guide assembly comprises a guide block connected to the outer wall of the scraper, a guide groove is formed on the inner wall of the storage tank body, and the guide block is slidably connected to the guide groove.

[0010] Preferably, the expansion component includes a accommodating cavity, an auxiliary plate, a sliding rod, a moving block and an adjusting component capable of driving the moving block to reciprocate along the axis of the threaded rod. The accommodating cavity is provided in the scraper, and the accommodating cavity is divided into an upper and lower layer. An expansion groove penetrating the outer wall of the scraper is provided in the accommodating cavity, and an auxiliary plate slidably connected to the inner wall of the storage tank body is slidably connected in the expansion groove.

The upper surface of the scraper is rotatably connected with bolts distributed circumferentially. The baffle is provided with threaded holes matching the bolts, and the bolts are threadedly connected to the baffle.

[0013] Compared with the prior art, the above technical solution of the utility model has the following beneficial technical effects:

[0014] As the scraper itself wears, the distance between it and the inner wall of the tank body increases. At this time, the bolt is adjusted to drive the baffle and the moving block to move downward. The movement of the moving block causes the sliding rod in the sliding groove to drive the auxiliary plate to move toward the inner wall of the tank body. The staggered auxiliary plates extend out and slide against the inner wall of the tank body to clean the tank body when the scraper moves, so that the scraper can still stably clean the tank body after wear. At the same time, the weighing sensor at the bottom of the tank body can measure the changes in the latex in the side tank body. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The cleaning mechanism includes a cleaning component and an expansion component. The cleaning component is arranged at the axis of the storage tank body 1 and drives the scraper 5 to move back and forth. The expansion component is arranged inside the scraper 5. The expansion component drives the outer peripheral wall of the scraper 5 to expand and slide in connection with the inner wall of the storage tank body 1. The latex is discharged outward from the discharge pipe. The weighing sensor 3 can detect the change of its weight and display it on the display 4 on the storage tank body 1. After the latex is discharged, the inner wall of the storage tank body 1 is cleaned by the cleaning component. The scraper 5 fits with the inner wall of the storage tank body 1 and is cleaned under the drive of the threaded rod 7. After the scraper 5 is worn, the auxiliary plate 11 in the expansion component moves outward to contact the storage tank body 1, thereby removing the latex still remaining on the inner wall of the storage tank body 1.

[0024] The cleaning assembly includes a motor 6, a threaded rod 7, and a guide assembly for limiting the rotation of the scraper 5 with the threaded rod 7. The motor 6 is connected to the top of the storage tank body 1, and the output end of the motor 6 passes through the storage tank body 1 and is connected to the threaded rod 7. The scraper 5 is provided with a threaded hole matching the threaded rod 7, and the threaded rod 7 passes through the threaded hole and is rotatably connected to the storage tank body 1. A guide assembly is provided on the outer peripheral wall of the scraper 5. After the motor 6 is started, the threaded rod 7 is driven to rotate. When the threaded rod 7 rotates, the scraper 5 is driven by the thread to move down and contact the inner wall of the storage tank body 1 to clean it to avoid waste of latex and blockage of the discharge port.

[0025] The guide assembly includes a guide block 8, which is connected to the outer wall of the scraper 5. A guide groove 9 is provided on the inner wall of the storage tank body 1. The guide block 8 is slidably connected to the guide groove 9. When the scraper 5 moves, the guide block 8 moves in the guide groove 9. The guide groove 9 limits and guides the scraper 5 to prevent it from rotating with the rotation of the threaded rod 7.

[0026] In this embodiment, the cleaning component is driven by the motor 6 to move the scraper 5 along the axis of the threaded rod 7 toward the bottom surface of the tank body 1, and the scraper 5 contacts the inner wall of the tank body 1 for cleaning. The expansion component drives the baffle 17 to move downward by screwing the bolt 18 in the adjustment component. When the baffle 17 moves downward, it drives the truncated cone-shaped moving block 13 to move downward. The sliding groove 15 and the sliding rod 12 on the moving block 13 release the auxiliary plate 11 to move along the expansion groove 14 toward the inner wall of the tank body 1. The two layers of auxiliary plates 11 cooperate with the scraper 5 to clean to reduce the waste of latex and the possibility of clogging the discharge pipe and affecting normal operation.

When the moving block 13 moves downward along the axis of the threaded rod 7, the sliding groove 15 on its outer circumferential surface slides with the sliding rod 12. Due to the angle of the moving block 13, when the moving block 13 moves downward, the sliding rod 12 pushes the auxiliary plate 11 to move toward the inner wall of the storage tank body 1, and the threaded rod 7 drives the scraper 5 to move so that the auxiliary plate 11 cleans the storage tank body 1.

[0029] The sliding grooves 15 and the auxiliary plates 11 are staggered on the upper and lower sides of the accommodating cavity 10. After the auxiliary plates 11 expand outward, there are fan-shaped gaps between the auxiliary plates 11 in the same plane.
