Description

Technical Field

[0001] This application relates to the field of solenoid valve installation technology for quantitative dispensing machines, and in particular to a feed valve assembly for a quantitative dispensing machine. Background Technology

[0002] A metering dispensing machine is an industrial device used to precisely control the amount of adhesive dispensed. It ensures that the amount of adhesive in each drop remains consistent during the production process and is widely used in industries such as electronics, LED, and automobiles that require high-precision adhesive application.

[0003] In existing quantitative dispensing machines, the feed valve assembly has a solenoid valve installed at a fixed position on the equipment. The solenoid valve is connected to the dispensing valve by an air pipe. The solenoid valve and the dispensing valve are far apart, and the air pipe is long. After the solenoid valve is activated, the air path then transmits the air to the dispensing valve, which makes the opening and closing response time of the dispensing valve even longer.

[0004] Therefore, we propose a feed valve assembly for a quantitative dispensing machine. Utility Model Content

[0005] To address the shortcomings of the existing production technology, the applicant provides a feed valve assembly for a quantitative dispensing machine, which has a more compact structure, shortens the air path length between the solenoid valve and the glue valve, and allows for faster response speed when the glue valve opens and closes.

[0006] The technical solution adopted in this application is as follows: A feed valve assembly for a quantitative dispensing machine includes: Glue valve; Valve plate, fixedly connected to the glue valve; Solenoid valve, fixedly connected to valve plate; The valve plate contains an intake passage, an exhaust passage, and an exhaust passage that are not interconnected with each other. One end of the air intake channel is connected to the air intake port of the solenoid valve, and the other end of the air intake channel is connected to air; one end of the air outlet channel is connected to the air outlet port of the solenoid valve, and the other end of the air outlet channel is connected to the air intake port of the rubber valve; one end of the exhaust channel is connected to the exhaust port of the solenoid valve, and the other end of the exhaust channel is connected to air.

[0007] Its further features are: The valve plate is also provided with a through hole, which is connected to the air outlet channel. A bolt is installed in the through hole to fix the valve plate and the rubber valve. The bolt is provided with a first channel connected to the air inlet of the rubber valve. The bolt is also provided with a second channel connected to the first channel. After the bolt is tightened, the second channel is connected to the air outlet channel.

[0008] Both ends of the bolt are equipped with sealing rings. After the bolt is tightened, the two sealing rings are located on both sides of the air outlet channel. The diameter of the bolt at the second channel is smaller than the diameter of the through hole, and the second channel is connected to the through hole.

[0009] The bolt is also provided with a third channel, which is connected to the first channel and is in a different direction from the second channel.

[0010] An air intake pipe is provided at one end of the air intake channel that is connected to the air.

[0011] A muffler is installed at one end of the exhaust passage that is connected to the air.

[0012] The solenoid valve is equipped with one air inlet, two air outlets, and two exhaust outlets, with two corresponding air outlet channels, two bolts, and two air inlets for the rubber valve.

[0013] The exhaust passage is connected to the two exhaust ports of the solenoid valve.

[0014] The beneficial effects of this application are as follows: This application features a compact and reasonable structure, and is easy to operate. Air enters the intake channel from the intake pipe, and then from the intake channel into the intake port of the solenoid valve. Part of the air inside the solenoid valve enters the exhaust channel from the solenoid valve's outlet, while another part of the air enters the exhaust channel from the solenoid valve's exhaust port. Air in the exhaust channel enters the intake port of the rubber valve. Air in the exhaust channel is discharged to the valve plate. Noise is reduced by installing a silencer in the exhaust channel. The structure is more compact, and the air path length between the solenoid valve and the rubber valve is shortened, resulting in a faster response speed for the rubber valve to open and close.

[0015] In addition, this application also has the following advantages: (1) Bolts fix the valve plate and the glue valve, and also connect the air inlet of the valve plate and the glue valve. Bolts achieve both air passage and fixing functions, which can save the processing steps of the valve plate, and the assembly of the valve plate and the glue valve is also more convenient.

[0024] The specific embodiments of this application are described below with reference to the accompanying drawings.

[0025] like Figures 1-7 As shown, a feed valve assembly for a quantitative dispensing machine includes a solenoid valve 1, a valve plate 2, and a dispensing valve 3.

[0026] Solenoid valve 1 is fixedly connected to valve plate 2, and valve plate 2 is fixedly connected to glue valve 3.

[0027] The valve plate 2 has an air intake channel 201, one end of which is connected to the air intake of the solenoid valve 1, and the other end of which is connected to an air intake pipe 205 and connected to air. The valve plate 2 also has an air outlet channel 202, one end of which is connected to the air outlet of the solenoid valve 1, and the other end of which is connected to the air intake of the rubber valve 3. The valve plate 2 also has an exhaust channel 203, one end of which is connected to the exhaust port of the solenoid valve 1, and the other end of which is connected to a muffler and connected to air. The air intake channel 201, air outlet channel 202, and exhaust channel 203 are not interconnected.

[0028] Air enters the intake passage 201 through the intake pipe 205, and then enters the intake port of the solenoid valve 1 through the intake passage 201. Part of the air in the solenoid valve 1 enters the exhaust passage 202 through the exhaust port of the solenoid valve 1, and another part of the air in the solenoid valve 1 enters the exhaust passage 203 through the exhaust port of the solenoid valve 1. The air in the exhaust passage 202 enters the intake port of the rubber valve 3. The air in the exhaust passage 203 is discharged to the valve plate 2. A silencer is installed on the exhaust passage 203 to reduce noise.

[0029] In one embodiment, the valve plate 2 is further provided with a through hole 204, which communicates with the air outlet channel 202. A bolt 4 is provided in the through hole 204 to fix the valve plate 2 and the rubber valve 3. The bolt 4 is provided with a first channel 401 that communicates with the air inlet of the rubber valve 3, and a second channel 402 that communicates with the first channel 401. After the bolt 4 is tightened, the second channel 402 communicates with the air outlet channel 202.

[0030] Bolt 4 secures valve plate 2 and rubber valve 3, and also connects the air inlets of valve plate 2 and rubber valve 3. Bolt 4 serves both to allow air to pass through and to fix the valve plate, saving on the processing steps of valve plate 2 and making the assembly of valve plate 2 and rubber valve 3 more convenient.

[0031] In one embodiment, sealing rings are provided at both ends of the bolt 4. After the bolt 4 is tightened, the two sealing rings are respectively located on both sides of the air outlet channel 202. The diameter of the bolt 4 at the second channel 402 is smaller than the diameter of the through hole 204. The second channel 402 is connected to the through hole 204, so that the air in the air outlet channel 202 enters the through hole 204 and then enters the second channel 402 from the through hole 204. The air enters the first channel 401 from the second channel 402 and then enters the air inlet of the rubber valve 3 through the first channel 401.

[0032] In one embodiment, the bolt 4 is further provided with a third channel 403, which is connected to the first channel 401 and is in a different direction from the second channel 402. When the second channel 402 is not aligned with the air outlet channel 202, the air in the through hole 204 can enter the first channel 401 through the second channel 402 and the third channel 403, thereby improving the air delivery efficiency.

[0033] In one embodiment, the solenoid valve 1 is provided with one air inlet, two air outlets, and two exhaust ports, with two corresponding exhaust channels 202, two bolts 4, two air inlets for the rubber valve 3, and exhaust channels 203 connected to the two exhaust ports of the solenoid valve 1 respectively.

[0034] In practical use, air enters the intake passage 201 through the intake pipe 205, and then enters the intake port of the solenoid valve 1 from the intake passage 201. A portion of the air inside the solenoid valve 1 enters the exhaust passage 202 from the outlet port of the solenoid valve 1, while another portion enters the exhaust passage 203 from the exhaust port of the solenoid valve 1. The air in the exhaust passage 202 enters the intake port of the rubber valve 3. The air in the exhaust passage 203 is discharged to the valve plate 2. A silencer is installed on the exhaust passage 203 to reduce noise. The structure is more compact, and the air path length between the solenoid valve 1 and the rubber valve 3 is shortened, resulting in a faster opening and closing response speed for the rubber valve 3.

[0035] The above description is an explanation of this application and not a limitation thereof. The scope of this application is defined by the claims. Within the scope of protection of this application, any form of modification may be made.
