Description

Technical Field

[0001] This application relates to the field of unsaturated resin filling technology, and in particular to an automatic quantitative filling device for unsaturated resin. Background Technology

[0002] Unsaturated resin refers to a polymer compound containing unsaturated double bonds, which is produced by the condensation reaction of diacids and diols. Unsaturated polyester resin is a thermosetting resin that can be cured into an insoluble and infusible polymer network under the action of heat or an initiator. In the production process of unsaturated resin, a filling process is required. After the filling equipment of some existing unsaturated resins stops filling, a small amount of residual resin will still drip, which affects the cleanliness of the working environment and causes waste.

[0003] Chinese patent CN105152112A, entitled "An Integrated Mechanism for Quantitative Filling," describes a mechanism where a drive motor lowers a valve core to block the filling nozzle outlet. The liquid to be filled enters the filling container through the feed channel on the valve core. Simultaneously, the quantitative extrusion component gradually rises, reducing its encroachment on the filling container. After quantitative filling, the drive motor raises the valve core, positioning the feed channel outlet between two sealing rings to prevent material from entering the filling container. At the same time, the drive motor lowers the quantitative extrusion component, squeezing the filling liquid out of the filling nozzle until the extruded volume reaches a set value.

[0004] Chinese patent CN114735255A, entitled "A Quantitative Filling Machine for Liquid Filling", improves filling accuracy by setting a weighing chamber to control the filling volume at one time; it can set multiple groups of filling barrels for individual control; and it improves control stability by using a mechanical structure to reduce the use of solenoid valves.

[0005] In the prior art, such as the aforementioned patents, during the liquid filling process, pumps are typically used to achieve quantitative filling. However, prolonged use of the pump can lead to inaccurate filling volume and increased operating costs. Furthermore, dripping is prone to occur after filling, affecting the cleanliness of the working environment and causing waste, as the pump cannot absorb any incompletely dripped liquid. Therefore, there is room for improvement in existing automatic quantitative filling equipment. Summary of the Invention

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Please see Figure 1-11 An automatic quantitative filling device for unsaturated resin provided in this embodiment of the invention includes a mounting plate 1; a fixed cylinder 2, which is installed in the middle of the upper end of the mounting plate 1, the fixed cylinder 2 having a cylindrical hollow structure and an open structure at the lower front end; a rotating assembly 3, which is installed on the upper end of the mounting plate 1, the rear side of the rotating assembly 3 being located inside the open structure at the front end of the fixed cylinder 2; a feeding assembly 4, which is symmetrically installed on the upper end of the mounting plate 1, the feeding assembly 4 being used to transport the filling bottles to the rotating assembly 3 and output the filling bottles that have been filled on the rotating assembly 3 to the right; and a filling assembly 5, which is installed inside the fixed cylinder 2, the lower end of the filling assembly 5 being connected to the rotating assembly 3, the lower end of the filling assembly 5 rotating synchronously with the rotating assembly 3, and the filling assembly 5 being used to automatically and quantitatively fill the unsaturated resin into the filling bottles one by one.

[0034] In the above technical solution, the feeding component 4 on the left side of the mounting plate 1 feeds the filling bottles one by one into the rotating component 3. The rotating component 3 drives the filling bottles and the lower end of the filling component 5 to rotate synchronously. When the filling bottles enter the inner side of the fixed cylinder 2, the filling component 5 automatically and quantitatively fills the unsaturated resin into the filling bottles one by one. After the filling component 5 finishes filling, the feeding component 4 on the right side of the mounting plate 1 sends the filling bottles out one by one, thereby realizing the function of continuous quantitative filling of unsaturated resin.

[0035] See Figures 3-4 As shown, as a preferred technical solution in this embodiment, the rotating component 3 includes a support frame 31, a drive motor 32, and a rotating frame 33. The support frame 31 is installed on the upper end of the mounting plate 1. The drive motor 32 is installed inside the support frame 31 through a motor seat. The rotating frame 33 is installed on the outside of the support frame 31 through a bearing. The output shaft of the drive motor 32 is connected to the rotating frame 33. Arc-shaped grooves are evenly arranged on the outside of the rotating frame 33, and negative pressure adsorption holes are evenly installed in the arc-shaped grooves.

[0036] In the above technical solution, when the feeding component 4 on the left side of the mounting plate 1 conveys the filling bottle, the arc groove on the rotating frame 33 can correspond to the filling bottle, so that the filling bottle can just enter the interior of the rotating frame 33 when it is conveyed to the right. The negative pressure adsorption hole on the rotating frame 33 can adsorb and fix the filling bottle, ensuring that the filling bottle can be in close contact with the rotating frame 33. When the filling of the bottle is completed, the negative pressure adsorption hole stops adsorbing, and the filled bottle enters the feeding component 4 on the right side of the mounting plate 1.

[0037] See Figures 3-4As shown, in this preferred embodiment, the feeding assembly 4 includes a conveying platform 41, a baffle 42, and a feeding rack 43. The conveying platform 41 is installed on the outer side of the mounting plate 1, and baffles are symmetrically installed on the conveying platform 41. The feeding rack 43 is installed on the mounting plate 1, and the middle part of the feeding rack 43 is connected to the output shaft of the motor. The feeding rack 43 has a circular structure and slots are evenly arranged on the feeding rack 43. The baffle 42 is provided on the mounting plate 1. The baffle 42 has an arc-shaped structure and is coaxial with the feeding rack 43. One end of the baffle 42 is connected to the baffle, and the other end of the baffle 42 is in close contact with the rotating assembly 3.

[0038] In the above technical solution, when the filling bottle is placed on the conveying platform 41, the conveying platform 41 can drive the filling bottle to be conveyed horizontally to the right. The baffle and the baffle frame 42 play a role in protecting the filling bottle and preventing the filling bottle from tipping over during the conveying process. The slot on the feeding frame 43 corresponds to the arc groove of the rotating frame 33. When the feeding frame 43 rotates, the filling bottle inside the slot can just enter the arc groove of the rotating frame 33, thereby realizing the function of feeding and positioning the filling bottle one by one.

[0039] See Figures 2-6 As shown, in this preferred embodiment, the filling assembly 5 includes a storage tank 51, a rotating disk 52, a connecting column 53, a rotating ring 54, a connecting pipe 55, an injection unit 56, and a pressing unit 57. The storage tank 51 is installed inside the fixed cylinder 2. The storage tank 51 is filled with unsaturated resin in the middle. The rotating disk 52 is installed at the lower end of the storage tank 51 through a sealed bearing. The lower end of the rotating disk 52 is connected to the rotating assembly 3 through the connecting column 53. A rotating ring 54 is provided on the outside of the rotating disk 52. A connecting pipe 55 is evenly installed between the rotating ring 54 and the rotating disk 52. A one-way valve is installed in the middle of the connecting pipe 55. A slot is evenly provided on the outside of the rotating ring 54. An injection unit 56 is installed in the slot. The injection unit 56 is connected to the inside of the rotating disk 52 through the connecting pipe 55. A pressing unit 57 is installed on the outside of the storage tank 51. The lower end of the pressing unit 57 is connected to the injection unit 56.

[0040] In the above technical solution, the prepared unsaturated resin is filled into the storage tank 51. When the filling bottle moves synchronously with the rotating frame 33 into the fixed cylinder 2, the injection unit 56 first moves downward to the upper part of the filling bottle. Then, the pressing unit 57 presses downward to inject the unsaturated resin inside the injection unit 56 into the filling bottle. After the injection unit 56 completes the injection, the injection unit 56 first moves upward to reset. Then, when the pressing unit 57 moves upward again, the lower end of the injection unit 56 closes, so that the pressing unit 57 can enter the injection unit 56 from the storage tank 51 through the connecting pipe 55. The function of quantitative filling of unsaturated resin can be realized by the up-and-down reciprocating motion of the pressing unit 57.

[0041] It should be noted that a one-way valve is installed inside the connecting pipe 55. When the pressing unit 57 moves upward, the injection unit 56 is under negative pressure, so that the unsaturated resin inside the storage tank 51 can only be injected into the injection unit 56 through the one-way valve. When the pressing unit 57 moves downward, the one-way valve closes, and the unsaturated resin inside the pressing unit 57 can be injected downward.

[0042] See Figures 8-9 As shown, in this preferred embodiment, the injection unit 56 includes an injection frame 561, an injection piston 562, a pneumatic piston 563, a pressure plate 564, a guide column 565, a connecting frame 566, an injection component 567, and a negative pressure component 568. The injection frame 561 has a rectangular structure and is installed in a slot on the outside of the rotating ring 54 by screws. An injection chamber is provided in the middle of the injection frame 561, and pneumatic chambers are evenly distributed on the outside of the injection frame 561. The injection piston 562 is installed at the upper end of the injection chamber. A pneumatic piston 563 is installed at the upper end of the pneumatic chamber. The upper ends of the injection piston 562 and the pneumatic piston 563 are connected by a pressure plate 564. A guide column 565 is installed at the lower end of the pneumatic chamber. A connecting frame 566 is installed between the lower ends of the guide columns 565. An injection component 567 is installed at the lower end of the injection chamber. The lower end of the injection component 567 is located inside the connecting frame 566. A negative pressure component 568 that cooperates with the injection component 567 is installed inside the connecting frame 566. The negative pressure component 568 is connected to the inside of the pneumatic chamber through the guide column 565.

[0043] In the above technical solution, the injection chamber is connected to the inside of the storage tank 51 through the connecting pipe 55. When the injection piston 562 moves upward, the injection piston 562 causes the inside of the injection chamber to be in a negative pressure state, so that the unsaturated resin inside the storage tank 51 can enter the inside of the injection chamber through the connecting pipe 55. When the filling bottle is filled, the injection element 567 moves downward and extends into the upper end of the filling bottle. Then, the pressure plate 564 drives the injection piston 562 to move downward, and the one-way valve inside the connecting pipe 55 closes. The unsaturated resin inside the injection chamber can then be injected into the filling bottle through the injection element 567. After the filling is completed, the injection element 567 returns to the initial position, and the injection piston 562 repeats the above steps, thereby realizing the function of continuous filling.

[0044] It should be noted that the pneumatic piston 563 moves synchronously with the filling piston 562. The pneumatic piston 563 is slidably disposed inside the pneumatic chamber, which is connected to the negative pressure component 568 through the air guide column 565. When the pneumatic piston 563 moves upward, the gas inside the pneumatic chamber moves upward, causing the negative pressure component 568 to be in a negative pressure state. This prevents the unsaturated resin remaining on the filling component 567 from dripping, thus preventing the unsaturated resin from dripping onto the outer surface of the filling bottle and ensuring that the surface of the filling bottle is not contaminated.

[0045] See Figure 10 As shown, in this preferred embodiment, the injection component 567 includes a fixed sleeve 5671, a sliding sleeve 5672, a connecting spring 5673, an injection head 5674, and a guide rod 5675. The fixed sleeve 5671 is installed at the lower end of the injection cavity, and the sliding sleeve 5672 is slidably arranged on the outer side of the lower end of the fixed sleeve 5671. A sealing ring is evenly arranged between the sliding sleeve 5672 and the fixed sleeve 5671. The connecting spring 5673 is installed on the fixed sleeve 5671. The injection head 5674 is installed at the lower end of the sliding sleeve 5672. The guide rod 5675 is installed in the middle of the sliding sleeve 5672. A guide groove that cooperates with the guide rod 5675 is provided on the inner wall of the fixed cylinder 2. The middle part of the guide groove is inclined inward.

[0046] In the above technical solution, the end of the guide rod 5675 is movably disposed inside the guide groove. When the guide groove tilts downward, the guide groove drives the sliding sleeve 5672 to move downward through the guide rod 5675, so that the injection head 5674 can extend into the upper part of the filling bottle. After the unsaturated resin is filled, the upward tilting guide groove drives the sliding sleeve 5672 to move upward, so that the sliding sleeve 5672 drives the injection head 5674 to return to the initial position. The lower end of the injection head 5674 is sealed to prevent excess unsaturated resin from flowing out and to ensure the injection amount of unsaturated resin.

[0047] See Figure 11As shown, as a preferred technical solution of this embodiment, the negative pressure component 568 includes a negative pressure frame 5681, an ear seat 5682, and a plug-in post 5683. The negative pressure frame 5681 has a cylindrical structure. The ear seats 5682 are evenly arranged at the lower end of the negative pressure frame 5681. The plug-in post 5683 is installed on the ear seat 5682. The plug-in post 5683 is connected to the air pressure chamber through the air guide column 565. The negative pressure frame 5681 has a conical groove inside.

[0048] In the above technical solution, the pneumatic piston 563 moves synchronously with the pressing unit 57. After the injection is completed, the pressing unit 57 moves upward and the pneumatic piston 563 moves upward synchronously, so that the inside of the pneumatic chamber is in a negative pressure state, and the inside of the negative pressure frame 5681 is also in a negative pressure state. Thus, the negative pressure frame 5681 can adsorb and fix the unsaturated resin that has not completely dripped, and avoid the phenomenon of long-term accumulation and dripping of unsaturated resin.

[0049] It should be noted that when the unsaturated resin is injected, the pneumatic piston 563 moves downward, allowing the gas inside the pneumatic chamber to move downward, and thus the accumulated unsaturated resin can drip downward synchronously.

[0050] Continue reading Figure 11 As shown, in this preferred embodiment, rectangular grooves are uniformly arranged on the inner wall of the conical groove, a diaphragm is arranged on the outer side of the rectangular groove, and the inside of the rectangular groove is connected to the inside of the plug-in post 5683.

[0051] In the above technical solution, the diaphragm serves to seal the rectangular groove. When the pneumatic piston 563 moves upward, the inside of the pneumatic chamber is under negative pressure, and the diaphragm moves into the rectangular groove. As a result, the unsaturated resin that has not completely dripped can be collected inside the rectangular groove, preventing the unsaturated resin from dripping downward. When the pneumatic piston 563 moves downward, the gas inside the pneumatic chamber drives the diaphragm to extend outward, allowing the unsaturated resin accumulated inside the rectangular groove to drip downward, ensuring that the unsaturated resin can only be injected when the injection part 567 moves downward.

[0052] See Figures 7-8 As shown, as a preferred technical solution of this embodiment, the pressing unit 57 includes a connecting rod 571 and a guide frame 572. The upper end of the injection unit 56 is equipped with a connecting rod 571, which has an F-shaped structure. The outer side of the storage tank 51 is equipped with a guide frame 572, and the connecting rod 571 is slidably disposed on the guide frame 572.

[0053] In the above technical solution, the connecting rod 571 slides on the guide frame 572. When the guide frame 572 tilts downward, the connecting rod 571 drives the injection unit 56 to move downward to inject material. When the guide frame 572 tilts upward, the connecting rod 571 drives the injection unit 56 to move downward, so that the unsaturated resin inside the storage tank 51 can enter the injection cavity.

[0054] It should be noted that when the guide frame 572 tilts downward, the filling component 567 extends downward into the filling bottle, and when the guide frame 572 tilts upward, the filling component 567 returns to its initial position.

[0055] See Figure 7 As shown, as a preferred technical solution in this embodiment, the guide frame 572 is an inclined annular structure, and the upper and lower sides of the guide frame 572 are provided with limiting grooves that cooperate with the connecting rod 571.

[0056] In the above technical solution, the limiting groove serves to limit the connecting rod 571, so that the connecting rod 571 can slide on the guide frame 572 continuously, preventing the connecting rod 571 from falling off the guide frame 572, and ensuring that the unsaturated resin can achieve continuous injection processing.

[0057] It should also be noted that the guide frame 572 is detachable. By replacing the guide frame 572 with different inclinations, the descent height of the connecting rod 571 can be adjusted, thereby enabling the function of adjusting the injection volume and satisfying the function of adjusting different injection volumes.

[0058] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
