Description

Technical Field

[0001] This utility model relates to a container for material storage, specifically a device for quantitatively dispensing paste. Background Technology

[0002] A paste removal device is a device that uses modern industrial methods to squeeze and expel paste from a container. The entire removal process needs to be fast, efficient, clean, and hygienic.

[0003] The application number is 2015104360462, and the patent name is: A paste dispensing device. Although it can dispense paste-like objects, the structure of the dispensing device is too complicated, making it easy to be damaged and inconvenient to maintain.

[0004] The application number is 2005200950284, and the patent name is: Ointment quantitative extrusion box. The ointment can be extruded by manually pressing the button. It is only suitable for ordinary packaging in daily life and has a limited scope of use. At the same time, the structure of this device requires manual operation, which is time-consuming and laborious.

[0005] This application is based on publication number CN109229827B, entitled "A Device for Quantitatively Removing Paste." The device comprises: a first tubular object, a second tubular object located within the first tubular object, a valve core fixed to the output end of the second tubular object and capable of closing or opening the paste unloading channel on the first tubular object as the second tubular object moves relative to the first tubular object, and a reset mechanism for restoring the second tubular object to its original position. The device of this invention is very simple; in embodiments of this invention, it consists of only three components. Practical application has shown that its operation is highly reliable.

[0006] During use, the applicant discovered that the lack of protective devices for the valve body and valve core could contaminate the extruded paste. Furthermore, using a spring as the power source for extruding the paste was inconvenient and the spring was prone to damage, affecting the normal operation of the entire device. Therefore, improvements were needed to address the aforementioned technical problems. Utility Model Content

[0007] The purpose of this utility model is to provide a device with a more reasonable structural design, ingenious concept, convenient operation, easy installation and disassembly, low processing cost, convenient paste dispensing, and protection for the valve body and valve core, making it safer to dispense paste in a quantitative manner.

[0008] This utility model discloses a device for quantitatively removing paste, comprising a valve body, a valve core installed inside the valve body, a valve seat fixedly installed on the bottom surface of the valve body, and a fixed protrusion fixedly connected to the inner wall of the valve seat; a fixed stop block fixedly connected to the outer wall of the valve body; a second outer shell sleeved on the outside of the valve body; a first outer shell connected to the surface of the second outer shell; the first outer shell includes two half-shells, and baffles are fixedly installed on the inner walls of the two half-shells respectively, with the positions of the baffles corresponding to the positions of the fixed stop blocks.

[0009] A second outer shell is fitted onto the outside of the valve body, and the surface of the second outer shell is connected to the first outer shell. The first and second outer shells can protect the valve body and valve core, preventing external dust and other contaminants from harming them. In particular, after the paste is squeezed out, it can effectively protect the paste at the valve core opening, preventing the paste from being contaminated and achieving the purpose of cleaning and removing the paste.

[0010] The number of fixed blocks and baffles is four. The fixed blocks are located on the outer wall of the valve body and are symmetrically arranged along the center line of the valve body. The baffles are arranged in pairs and are located on the inner walls of the two half-shells respectively.

[0011] A fixed stop is fixedly connected to the outer wall of the valve body, and baffles are fixedly installed on the inner walls of the two half-shells respectively. When the paste is squeezed from the bottom surface of the valve core into the valve core, and then into the cavity formed by the valve core and the valve body, the paste is squeezed into the surface of the valve core and squeezed out from the port of the valve core. As the paste is squeezed, the valve body moves upward, and the fixed stop on the outer wall of the valve body also moves upward. After the fixed stop contacts the baffle, the baffles on the inner walls of the two half-shells are lifted. During the lifting process, the two half-shells separate and can move in an arc trajectory to both sides along the center line of the valve body. The baffle contacts the fixed stop, and the fixed stop acts as a stop and limit for the baffle, which facilitates the separation of the two half-shells without affecting the operation of paste dispensing. It also facilitates the merging of the two half-shells. When merging, the two half-shells can move in an arc trajectory from both sides to the center along the center line of the valve body to complete the reset. After the two half-shells are merged, they can protect the port of the valve core. The operation is convenient, safe and reliable.

[0012] The first outer shell is fixedly connected to a limiting shell, which is respectively disposed in the two half-shells.

[0013] A limiting housing is fixedly connected inside the first outer casing to further protect the port of the valve core, thus achieving the purpose of double protection.

[0014] The valve body includes a small port diameter and a large port diameter. An iron ring is fixedly installed inside the valve body, and a first magnetic iron ring is fixedly installed on the inner wall of the valve body.

[0015] The small and large port diameters are designed for installing valve cores, making installation and disassembly convenient.

[0016] The valve core includes an outlet pipe, a column, a first gap, a connecting section, a second magnetic iron ring fixing pipe, a support frame, and a second gap. The surface of the fixing pipe is fixedly installed with a second magnetic iron ring, and the inner wall of the fixing pipe is fixedly connected with a support frame. There are three support frames, and the second gap is between the support frames. The surface of the support frame is fixedly connected with a connecting section, and the surface of the connecting section is fixedly connected with a column. There are two columns, and the first gap is between the columns. The surface of the column is fixedly connected with an outlet pipe.

[0017] A first magnetic iron ring is fixedly installed on the inner wall of the valve body, and a second magnetic iron ring is fixedly installed on the surface of the fixing tube. When the valve body moves upward along the valve core, the first and second magnetic iron rings generate a repulsive force, which gradually increases. As the paste is squeezed out, the valve body moves downward to reset. At this time, the repulsive force generated by the first and second magnetic iron rings gradually decreases, thus better achieving the reset of the valve body. The second magnetic iron ring fixedly installed on the surface of the fixing tube can attract the iron ring fixedly installed on the inner wall of the valve body, achieving an auxiliary reset function. It also serves to fix the valve core and valve body, resulting in good reset and fixation effect, resistance to damage, ease of maintenance, and long service life.

[0018] A housing base is fixedly installed on the bottom surface of the second outer shell. A fixing hole is opened on the bottom surface of the second outer shell, and a first fixing ring is fixedly installed through the fixing hole. The bottom surface of the first fixing ring is fixedly connected to the housing base.

[0019] The bottom surface of the second outer shell is fixedly installed with a shell base, which makes it easy to place the second outer shell anywhere and provides protection and support for the second outer shell; a first fixing ring is fixedly installed through the fixing hole, and the bottom surface of the first fixing ring is fixedly connected to the shell base, which is safe and reliable and has a compact structure.

[0020] Magnets are provided on the side walls of the first and second outer shells.

[0021] Magnets are provided on the side walls of the first and second outer shells. When the two half-shells are combined, they can facilitate the closure of the two half-shells, ensuring a secure and effective closure.

[0022] The second outer shell has holes on its side wall.

[0023] This utility model discloses a second structure of a device for quantitatively removing paste, comprising a valve body, a valve core installed inside the valve body, a fixed base fixedly connected to the bottom end of the valve core, connecting bolts fixedly installed on the side walls of the fixed base, a first inclined tie rod and a second inclined tie rod hinged to the connecting bolts, the connecting bolts being located at one end of the first inclined tie rod and the second inclined tie rod, the other end of the first inclined tie rod being hinged to the side wall of a first horizontal connecting rod by the connecting bolts, a first support frame fixedly connected to the surface of the first horizontal connecting rod, and a fixing ring fixedly connected to the side wall of the first horizontal connecting rod; the other end of the second inclined tie rod being hinged to the side wall of the second horizontal connecting rod by the connecting bolts, a second support frame fixedly connected to the surface of the second horizontal connecting rod, and a second fixing ring fixedly connected to the side wall of the second horizontal connecting rod, the second fixing ring being hinged to both side walls of the valve body by the connecting bolts; a semi-circular bracket fixedly connected to the side walls of the first support frame and the second support frame, a soft protective film covering the first support frame, the second support frame and the semi-circular bracket, the bottom end of the soft protective film being fixed to the side wall of the fixed base.

[0024] A first and a second diagonal tie rod are respectively installed on both sides of the side wall of the fixed base. When the valve core is filled with paste, the paste is squeezed and squeezed out through the port of the valve core. At this time, the paste drives the valve body to move upward along the valve core. During the upward movement of the valve body, the first support frame, the first horizontal connecting rod, the second support frame, and the second horizontal connecting rod move upward. Through the hinge action of the connecting bolts, the included angle between the first and second diagonal tie rods becomes smaller. Since the first diagonal tie rod and the first horizontal connecting rod are hinged, and the second diagonal tie rod and the second horizontal connecting rod are hinged, the first and second diagonal tie rods pull the first and second horizontal connecting rods downward. Since the first and second support frames are hinged, the first support frame can be pulled downward. The angle between the valve body and the second support frame increases, achieving the open state; the paste is squeezed out from the valve core port, achieving pressure relief, and the valve body moves downward along the valve core. The second magnetic iron ring fixedly installed on the surface of the fixed tube can attract each other with the iron ring fixedly installed on the inner wall of the valve body, achieving reset. The first and second diagonal pull rods drive the first and second horizontal connecting rods to push upward, and the angle between the first and second diagonal pull rods decreases, achieving closure between the first and second support frames. Since the first support frame, the second support frame, and the semi-circular bracket are covered with a soft protective film, it can protect the part of the valve core from which the paste comes out, keeping it clean and hygienic, preventing the paste from being contaminated, and making the operation simple and convenient.

[0025] The valve body includes a small port diameter and a large port diameter. An iron ring is fixedly installed inside the valve body, and a first magnetic iron ring is fixedly installed on the inner wall of the valve body.

[0026] The valve core includes an outlet pipe, a column, a first gap, a connecting section, a second magnetic iron ring, a fixed pipe, a support frame, and a second gap. A magnetic ring is fixedly installed on the surface of the fixed pipe, and a support frame is fixedly connected to the inner wall of the fixed pipe. There are three support frames, and the second gap is between the support frames. A connecting section is fixedly connected to the surface of the support frame, and a column is fixedly connected to the surface of the connecting section. There are two columns, and the first gap is between the columns. An outlet pipe is fixedly connected to the surface of the column, and the fixed pipe is fixedly connected to the fixed seat.

[0027] This utility model discloses a third structure of a device for quantitatively removing paste, comprising a valve body, a valve core installed inside the valve body, a fixed base fixedly connected to the bottom end of the valve core, and two support bases fixedly installed on the side walls of the fixed base, symmetrically arranged along the center line of the fixed base; the support bases are U-shaped, and a third support frame and a first gear are hinged to the side walls of the support bases by fixing bolts, with the third support frame and the first gear being fixedly connected; a fourth support frame and a second gear are hinged to the side walls of the support bases by fixing bolts, with the fourth support frame and the second gear being fixedly connected; a rack meshes between the first gear and the second gear, and the rack is fixedly installed on the side wall of the valve body by a connecting rod; a semi-circular bracket is fixedly connected to the side walls of the third support frame and the fourth support frame, and a soft protective film is covered by the third support frame, the fourth support frame, and the semi-circular bracket, with the bottom end of the soft protective film fixed to the side wall of the fixed base.

[0028] Support seats are installed on both sides of the side wall of the fixed seat. A third support frame and a first gear are hinged to the side wall of the support seat via fixing bolts. The third support frame and the first gear are fixedly connected. A fourth support frame and a second gear are hinged to the side wall of the support seat via fixing bolts. The fourth support frame and the second gear are fixedly connected. A rack meshes between the first gear and the second gear. The rack is fixedly installed on the side wall of the valve body via a connecting rod. When paste is filled into the valve core, the paste is squeezed and extruded through the port of the valve core. At this time, the paste drives the valve body to move upward along the valve core. During the upward movement of the valve body, the rack rotates between the first gear and the second gear, causing the valve body to move upward. When the rack rotates between the first and second gears, the third and fourth support frames open, allowing the paste to be squeezed out through the valve core's port, thus releasing pressure. The valve body moves downwards along the valve core. The second magnetic iron ring, fixedly installed on the surface of the fixed tube, attracts the iron ring fixedly installed on the inner wall of the valve body, achieving resetting. The third and fourth support frames close when the rack rotates between the first and second gears. Because the third and fourth support frames and the semi-circular bracket are covered with a soft protective film, the paste outlet at the valve core end is protected, ensuring cleanliness and hygiene, preventing contamination of the paste, and making operation simple and convenient.

[0029] The valve body includes a small port diameter and a large port diameter. An iron ring is fixedly installed inside the valve body, and a first magnetic iron ring is fixedly installed on the inner wall of the valve body.

[0030] The valve core includes an outlet pipe, a column, a first gap, a connecting section, a second magnetic iron ring, a fixed pipe, a support frame, and a second gap. The second magnetic iron ring is fixedly installed on the surface of the fixed pipe, and the support frame is fixedly connected to the inner wall of the fixed pipe. There are three support frames, and the second gap is between the support frames. The connecting section is fixedly connected to the surface of the support frame, and the column is fixedly connected to the surface of the connecting section. There are two columns, and the first gap is between the columns. The outlet pipe is fixedly connected to the surface of the column, and the fixed pipe is fixedly connected to the fixed seat.

[0031] The beneficial effects of this utility model are:

[0032] 1) A fixed stop is fixedly connected to the outer wall of the valve body, and baffles are fixedly installed on the inner walls of the two half-shells respectively. When the paste is squeezed from the bottom surface of the valve core into the inside of the valve core, and then into the cavity formed by the valve core and the valve body, the paste is squeezed into the surface of the valve core and squeezed out from the port of the valve core. As the paste is squeezed, the valve body moves upward, and the fixed stop on the outer wall of the valve body also moves upward. After the fixed stop contacts the baffle, the baffles on the inner walls of the two half-shells are lifted. During the lifting process, the two half-shells separate and can move in an arc trajectory along the center line of the valve body to both sides. The baffle contacts the fixed stop, and the fixed stop acts as a stop and limit for the baffle, which facilitates the separation of the two half-shells without affecting the operation of paste dispensing. It also facilitates the merging of the two half-shells. When merging, the two half-shells can move in an arc trajectory from both sides to the center along the center line of the valve body to complete the reset. After the two half-shells are merged, they can protect the port of the valve core. The operation is convenient, safe and reliable.

[0033] 2) A limiting housing is fixedly connected inside the first outer shell to further protect the port of the valve core, thus achieving the purpose of double protection.

[0034] 3) A first magnetic iron ring fixedly installed on the inner wall of the valve body and a second magnetic iron ring fixedly installed on the surface of the fixing tube generate a repulsive force when the valve body moves upward along the valve core. The repulsive force gradually increases. As the paste is squeezed out, the valve body moves downward to reset. At this time, the repulsive force generated by the first and second magnetic iron rings gradually decreases, thus better achieving the reset of the valve body. The second magnetic iron ring fixedly installed on the surface of the fixing tube can attract each other with the iron ring fixedly installed on the inner wall of the valve body, achieving an auxiliary reset function. It also serves to fix the valve core and valve body, resulting in good reset and fixation effect, resistance to damage, ease of maintenance, and long service life.

There are three support frames 707, and the second gap 708 is between the support frames 707. The connecting section 704 is fixedly connected to the surface of the support frame 707, and the column 702 is fixedly connected to the surface of the connecting section 704. There are two columns 702, and the first gap 703 is between the columns 702.

[0077] The soft protective film 27 is made of silicone film, PP, or PVC.

[0078] Instructions for use: The soft protective film 27 can be wrapped around the first support frame 10 and the semi-circular bracket 18, and the second support frame 13 and the semi-circular bracket 18 respectively. The bottom end of the soft protective film 27 is fixed to the side wall of the fixing seat 9. A valve core 7 can be installed in the large port diameter 502 and the small port diameter 501 of the valve body 5. The outlet pipe 701 of the valve core 7 extends out of the small port diameter 501, and the fixing pipe 706 of the valve core 7 extends to the outside of the large port diameter 502. The fixing pipe 706 is fixed in the fixing hole 202 of the second outer shell 2. When a paste is connected through the fixing pipe 706... The paste is fed into the container pipe through the fixed pipe 706, then through the second gap 708 and the first gap 703, finally entering the outlet pipe 701. The paste is extruded through the outlet pipe 701. At this time, the paste causes the valve body 5 to move upwards along the valve core 7. During this upward movement, the valve body 5 also causes the first support frame 10, the first horizontal connecting rod 11, the second support frame 13, and the second horizontal connecting rod 15 to move upwards. Through the hinge action of the connecting bolt 16, the included angle between the first diagonal tie rod 12 and the second diagonal tie rod 17 decreases. Because the first diagonal tie rod 12 and the first horizontal connecting rod 17... The connecting rods 11 are hinged together, and the second diagonal tie rod 17 is hinged together with the second horizontal connecting rod 15. Therefore, the first diagonal tie rod 12 and the second diagonal tie rod 17 pull the first horizontal connecting rod 11 and the second horizontal connecting rod 15 downward. Since the first support frame 10 and the second support frame 13 are hinged together, the angle between the first support frame 10 and the second support frame 13 can be increased, realizing the open state. After the paste is squeezed out from the port of the valve core 7, the pressure is released. The valve body 5 moves downward along the valve core 7. The second magnetic iron ring 705, which is fixedly installed on the surface of the fixed tube 706, can interact with the inner side of the valve body 5. The iron rings 503 fixed to the wall attract each other to achieve reset. The first diagonal tie rod 12 and the second diagonal tie rod 17 drive the first horizontal connecting rod 11 and the second fixed plate 15 to be pushed upward. The angle between the first diagonal tie rod 12 and the second diagonal tie rod 17 becomes smaller, realizing the closure between the first support frame 10 and the second support frame 13. Since the first support frame 10, the second support frame 13 and the semi-circular bracket 18 are covered with a soft protective film 27, it can protect the part of the valve core 7 from the paste, keeping it clean and hygienic, avoiding contamination of the paste, and making the operation simple and convenient.

[0083] Usage: The soft protective film 27 can be wrapped around the third support frame 19 and the semi-circular bracket 18, and the fourth support frame 22 and the semi-circular bracket 18 respectively. The bottom end of the soft protective film 27 is fixed to the side wall of the fixing seat 9.

The fixing pipe 706 is fixed in the fixing hole 202 of the second outer shell 2. When the end of the paste-containing pipe is connected through the fixing pipe 706, the paste enters through the fixing pipe 706, passes through the second gap 708 and the first gap 703, and finally enters the outlet pipe 701. The paste is squeezed out through the outlet pipe 701. At this time, the paste drives the valve body 5 to move upward along the valve core 7. During the upward movement of the valve body 5, the rack 23 and the first gear 2 When the first gear 20 and the second gear 24 rotate, the valve body 5 moves upward. This rotation between the rack 23 and the first gear 20 and the second gear 24 opens the third support frame 19 and the fourth support frame 22, allowing the paste to be squeezed out through the port of the valve core 7. After the paste is squeezed out, pressure is released, and the valve body 5 moves downward along the valve core 7. The second magnetic iron ring 705, which is fixedly installed on the surface of the fixed tube 706, attracts the iron ring 503 fixedly installed on the inner wall of the valve body 5, achieving a reset. The valve body 5 moves downward, and the rotation between the rack 23 and the first gear 20 and the second gear 24 closes the third support frame 19 and the fourth support frame 22. Since the soft protective film 27 covers the third support frame 19, the fourth support frame 22, and the semi-circular bracket 18, it can protect the paste outlet at the end of the valve core 7, keeping it clean and hygienic, preventing the paste from being contaminated, and making the operation simple and convenient.
