Description

Technical Field

[0001] The utility model relates to the field of filling, and more specifically, to a novel screw-rod quantitative filling machine. Background Art

[0002] Sealing agent is an upgraded product of grouting agent. The decorative and practical properties of seaming agent are obviously better than those of colored grouting agent, which solves the problems of unsightly and dirty seams of tiles. With the continuous improvement of people's living standards, people's pursuit of the beauty of interior decoration is increasing day by day. Therefore, in the process of laying tiles and floors, the use of seaming agent can better meet the needs of users.

[0003] The applicant has previously applied for a utility model patent entitled "Screw quantitative filling machine", with application number 2024200811570. The utility model patent is connected by setting a feed pipe, a storage tank and a discharge pipe, and then setting a three-way valve and a switching module. The switching module switches the connection relationship between the storage tank, the feed pipe and the discharge pipe by driving the rotating shaft in the three-way valve to rotate. A sealing plug is set in the storage tank, and then a pressure rod, a driving mechanism for driving the pressure rod to rise and fall, and a control mechanism for controlling the height position of the pressure rod are set. When filling, the feed pipe and the storage tank are connected through the three-way valve. Under the restriction of the pressure rod and the control mechanism, the sealing plug can only store a specific volume of raw materials in the storage tank, thereby achieving the effect of quantitative extraction of raw materials. Then, the switching module drives the rotating shaft to rotate, and then the three-way valve is switched to connect the storage tank and the discharge pipe, and then the pressure rod is driven down by the driving mechanism, and then the raw materials in the storage tank are quickly pushed into the container through the three-way valve and the discharge pipe in sequence through the sealing plug to achieve quantitative filling.

[0004] However, in actual use, the applicant found that some air would be mixed into the caulking agent during the extraction and filling process. Since the caulking agent is a relatively viscous liquid, the mixed gas is difficult to discharge, which will cause errors in the filling of the caulking agent and thus affect the compliance rate of the product filling.

[0005] Based on the above, the purpose of the utility model is to provide a new screw quantitative filling machine to solve the above problems. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a novel screw quantitative filling machine. The utility model arranges an ultrasonic generator and a vent pipe on the storage tank body, and the gas inside the raw material is dissolved, raised and released through ultrasonic generation, and the released air is discharged through the vent pipe. The liquid level gauge arranged on the cover body will measure whether the volume of the raw material after the gas is discharged meets the standard. When the volume of the raw material is less than the preset value, the raw material is injected into the storage tank again. After the volume of the raw material meets the standard, the valve on the vent pipe is closed, and the raw material is injected into the preset container, thereby eliminating the air in the raw material during the quantitative filling process, making the quantitative filling more accurate.

[0007] The above technical purpose of the utility model is achieved through the following technical solutions: a new screw quantitative filling machine, including a mounting frame, on which a feed pipe, a discharge pipe, a three-way valve, a storage tank, a switching module, a pressure rod, a driving mechanism and a control mechanism are arranged, the storage tank includes a tank body, a cover body is slidably arranged in the tank body, the cover body is fixedly connected to the pressure rod, a vent pipe and a liquid level meter are arranged on the cover body, a valve is arranged on the vent pipe, and an ultrasonic generator is arranged on the storage tank.

[0008] By adopting the above technical scheme, when it is necessary to fill the caulking agent, the feed pipe is connected to the external raw material conveying mechanism, the valve is opened, the storage tank is connected to the outside through the vent pipe, and then the raw materials are sequentially input into the storage tank through the feed pipe and the three-way valve through the external raw material conveying mechanism. Due to the limitation of the pressure rod, the height of the cover body is limited, thereby limiting the capacity of the storage tank for the caulking agent, so that the storage tank can only be filled with a specific volume of caulking agent, which has the effect of quantitative material extraction. During the injection of the caulking agent, the air in the storage tank will be discharged through the vent pipe, and the liquid level meter will measure the injection of the caulking agent. When the caulking agent fills the inner cavity of the storage tank, the ultrasonic generator is started, and the ultrasonic wave can produce a cavitation effect in the liquid, that is, a non-cavitation effect is formed. Countless tiny bubbles grow and collapse rapidly. This process can break the original bubbles and promote the release of dissolved gas in the liquid. The released gas will rise to the upper end of the inner cavity of the storage tank. At this time, the liquid level meter measures the caulking agent again. When the caulking agent is less than the preset value, the caulking agent is injected again through the external raw material conveying mechanism. When the caulking agent capacity is within the preset value range, the control valve is closed, and then the switching module drives the three-way valve to switch to the storage tank and the discharge pipe. Then, the driving mechanism drives the pressure rod to descend, thereby driving the cover body to descend and injecting the caulking agent in the storage tank into the container through the three-way valve and the discharge pipe. With this arrangement, the air in the raw materials can be eliminated during the quantitative filling process, making the filling operation more accurate.

[0009] The utility model is further configured as follows: the vent pipe is threadedly connected to the cover body, a diaphragm is arranged on the vent pipe, the diaphragm allows air to pass through and blocks viscous liquid, a limiting groove is arranged on the cover body to limit the diaphragm, a through groove communicated with the vent pipe is arranged on the limiting groove, and the diameter of the through groove is smaller than the diameter of the vent pipe.

[0010] The utility model is further configured as follows: a plurality of sealing rings are arranged on the cover body.

[0011] The utility model is further configured as follows: the switching module comprises a motor and a reduction mechanism, the output shaft of the motor is fixedly connected to the input shaft of the reduction mechanism, and the output shaft of the reduction mechanism is fixedly connected to the rotating shaft.

[0012] The utility model is further configured as follows: a proximity sensor is arranged on the mounting frame, and a contact cam matched with the proximity sensor is arranged on the output shaft of the speed reduction mechanism.

[0013] In summary, the utility model has the following beneficial effects:

[0014] The utility model arranges an ultrasonic generator and a vent pipe on the storage tank body, and the ultrasonic wave is used to dissolve the gas inside the raw material and release it by rising. The released air is discharged through the vent pipe, and a liquid level gauge arranged on the cover body measures whether the volume of the raw material after the gas is discharged meets the standard. When the volume of the raw material is less than a preset value, the raw material is injected into the storage tank again. After the volume of the raw material meets the standard, the valve on the vent pipe is closed, and the raw material is injected into a preset container. A diaphragm is arranged on the vent pipe to prevent the raw material from being discharged through the vent hole during the exhaust process. The detachable structure of the vent pipe is convenient for the user to replace the diaphragm, thereby eliminating the air in the raw material during the quantitative filling process, so that the quantitative filling is more accurate.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] The utility model is described in detail below in conjunction with the accompanying drawings.

[0025] A new type of screw quantitative filling machine, such as Figures 1 to 5As shown, it includes a mounting frame 1, on which are provided a feed pipe 2, a discharge pipe 3, a three-way valve 4, a storage tank 5, a switching module 6, a pressure rod 7, a driving mechanism and a control mechanism 8. The storage tank 5 includes a tank body 9 fixedly connected to the three-way valve, a cover body 10 is slidably connected inside the tank body 9, the cover body 10 is fixedly connected to the pressure rod 7, a vent pipe 11 and a liquid level meter 12 are provided on the cover body 10, the liquid level meter 12 is a radar liquid level sensor, a valve 13 is provided on the vent pipe 11, and an ultrasonic generator 14 is installed on the storage tank 5, and the ultrasonic generator 14 is an external wall-mounted ultrasonic defoamer.

[0026] Furthermore: the vent pipe 11 is threadedly connected to the cover body 10, and a diaphragm 15 is provided on the vent pipe 11. The diaphragm is a GORE-TEX membrane. The diaphragm 15 allows air to pass through and blocks viscous liquid. The cover body 10 is provided with a limiting groove 16 for placing and limiting the diaphragm 15. The limiting groove 16 is provided with a through groove 17 that is connected to the vent pipe 11, and the diameter of the through groove 17 is smaller than the diameter of the vent pipe 11.

[0027] Furthermore: a plurality of sealing rings 18 are installed on the cover body 10 .

[0028] Furthermore: the switching module 6 includes a motor 19 and a reduction mechanism 20, the reduction mechanism is a gear reduction box, the output shaft of the motor 19 is fixedly connected to the input shaft of the reduction mechanism 20, and the output shaft of the reduction mechanism 20 is fixedly connected to the rotating shaft of the three-way valve.

[0029] Furthermore: a proximity sensor 21 is provided on the mounting frame 1 , and a contact cam 22 cooperating with the proximity sensor 21 is fixedly connected to the output shaft of the speed reduction mechanism 20 .

[0030] Working principle: When it is necessary to fill the caulking agent, connect the feed pipe 2 with the external raw material conveying mechanism, open the valve 13, and make the storage tank 5 communicate with the outside world through the vent pipe 11, and then pass the raw materials through the feed pipe 2 and the three-way valve 4 in sequence into the storage tank 5 through the external raw material conveying mechanism. Due to the limitation of the pressure rod 7, the height of the cover body 10 is limited, thereby limiting the capacity of the caulking agent in the storage tank 5, so that the storage tank 5 can only be filled with a specific volume of caulking agent, which has the effect of quantitative material extraction.

[0031] During the process of injecting the caulking agent, the air in the storage tank 5 will be discharged through the vent pipe 11, and the liquid level meter 12 will measure the injection situation of the caulking agent. When the caulking agent fills the inner cavity of the storage tank 5, the ultrasonic generator 14 is started. The ultrasonic wave can produce a cavitation effect in the liquid, that is, countless tiny bubbles are formed and grow and collapse rapidly. This process can break the original bubbles and promote the rise and release of dissolved gas in the liquid. The released gas will rise to the upper end of the inner cavity of the storage tank 5.

[0032] At this time, the liquid level meter 12 measures the caulking agent again. When the caulking agent is less than the preset value, the caulking agent is injected again through the external raw material conveying mechanism. The diaphragm 15 can discharge the air in the storage tank 5. The caulking agent is a thick liquid and is not easy to pass through the diaphragm 15, thereby preventing the caulking agent from being discharged through the vent pipe 11 during injection. When the caulking agent capacity is within the preset value range, the control valve 13 is closed, and then the motor 19 and the speed reduction mechanism 20 drive the rotating shaft of the three-way valve 4 to rotate, thereby switching the three-way valve 4 to a state where the storage tank is connected to the discharge pipe 3, and the proximity sensor 2 1 By detecting the position of the contact cam, it is determined whether the shaft has rotated to the right position, and then the motor is controlled to stop running after the shaft rotates to the right position. It should be mentioned here that the number of contact cams can be changed according to the selection of the motor. If an ordinary motor is selected, two contact cams can be set to correspond to the two conduction modes of the three-way valve. When a servo motor is selected, only one contact cam needs to be set to ensure the accurate switching of the three-way valve. The cooperation of the motor 19 and the reducer can increase the switching speed and torque of the three-way valve, making the switching of the three-way valve 4 faster and more accurate.

[0033] Then, the pressure rod 7 is driven down by the driving mechanism (how the driving mechanism drives the pressure rod 7 to descend is described in detail in the patent application number 2024200811570, which will not be elaborated here), thereby driving the cover body 10 to descend and injecting the seam beautifying agent in the storage tank 5 into the container through the three-way valve 4 and the discharge pipe 3. With this arrangement, the air in the raw material can be eliminated during the quantitative filling process, making the filling operation more accurate.

[0034] During the above operation, the user can also connect the vent tube 11 to an external negative pressure device to form a quasi-vacuum in the storage tank 5 through the negative pressure device, which can further help the air in the caulking agent to rise and release. The user can also remove the vent tube 11 from the cover body 10 and replace the diaphragm 15 to ensure stable quantitative filling.

[0035] It is also necessary to mention that the electronic components used above can be controlled by a PLC controller and a preset program. Controlling the operation of electronic components by a PLC controller is a mature existing technology and will not be elaborated here.

[0036] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
