AI Technical Summary
Existing filling machines are prone to clogging the nozzle when spraying solid granular materials, resulting in poor material discharge.
The valve core adopts a valve core structure with a vertical shaft hole. The valve core is connected to the valve seat at the top of the horizontally set conveying pipeline. The valve core moves up and down under the action of power. The end of the valve core matches the valve port as a columnar object to ensure smooth material discharge and clear blockages when the valve is opened.
It effectively prevents nozzle blockage and ensures smooth material ejection, especially for materials containing solid particles, avoiding blockage and ensuring the continuity and efficiency of the filling process.

TECHNICAL FIELD
[0001] The present application relates to the field of filling technology, in particular to a filling machine. BACKGROUND
[0002] The existing filling machine, after outputting the material from the pipeline according to the set amount, closes the outlet through the valve to control the output amount. The valve of the prior art only closes the valve. Since the filled material is various, some of which are mixed with solid particles, such as nuts mixed in syrup, the ejection port is easily blocked by the solid material in the material, resulting in poor ejection of the subsequent material. SUMMARY
[0003] The present application aims to provide a filling machine which can overcome one or more of the above-mentioned shortcomings, prevent the ejection port from being blocked, and ensure smooth ejection of the material.
[0004] The filling machine of the present application is realized by comprising a material conveying pipeline and a valve arranged on the conveying pipeline and perpendicular to the conveying pipeline. The valve comprises a valve seat with an axial hole perpendicular to the conveying pipeline arranged on the upper part of the horizontally arranged conveying pipeline, a valve core driven by a power source to move up and down along the axial hole arranged on the valve seat, and a valve port arranged at the lower part of the conveying pipeline, the valve port facing the valve core, the valve port being a tubular hole, a sealing structure being arranged between the valve core and the axial hole, and the end of the valve core being a columnar object matched with the tubular hole of the valve port, the valve core being driven by the power source to penetrate into or away from the valve port.
[0005] In use, the material is conveyed to the conveying pipeline at a certain conveying pressure, the valve core is driven by the power source to move upwards when filling is needed, the columnar object at the lower end of the valve core is away from the valve port, the material is ejected from the valve port, the filling operation is completed, then the valve core is driven by the power source to move downwards, the columnar object at the lower end of the valve core is inserted into the valve port, and at the same time, the material remaining in the valve port is taken out of the valve port; since the end of the valve core is a columnar object matched with the tubular hole of the valve port, even if the material (such as nuts in syrup) is stuck in the valve port, it is also cleaned out of the valve port under the action of the columnar object. Since the columnar object is suspended in the conveying pipeline when the valve is opened, there is no obstacle around the columnar object, and the material in the conveying pipeline flows smoothly to the valve port when the valve is opened, ensuring smooth ejection of the material.
[0006] Preferably, the valve port is a tapered hole with a large upper opening and a small lower opening, and the taper of the tapered hole is 1-10 degrees.
[0007] If the pipe hole shaped valve port is a cylindrical valve port, once solid objects are retained between the pipe hole shaped valve port and the end of the columnar shaped valve core, the end of the columnar shaped valve core is easily stuck on the pipe hole shaped valve port, and the objects retained between the pipe hole shaped valve port and the end of the columnar shaped valve core are easily pressed against the pipe hole shaped valve port and are not easy to be cleaned out, which causes the end of the columnar shaped valve core to be unable to be smoothly inserted into the pipe hole shaped valve port. The existence of the conical hole causes the solid objects beside the end of the columnar shaped valve core to not be easily stuck between the conical hole and the end of the columnar shaped valve core, thereby avoiding the solid objects to be retained between the pipe hole shaped valve port and the end of the columnar shaped valve core.
[0008] Compared with the prior art, the present application has the advantages of preventing the nozzle from being blocked and ensuring smooth spraying of the material. BRIEF DESCRIPTION OF DRAWINGS

[0010] FIG. 1 is a structural schematic diagram of a filling machine according to Embodiment 1 of the present application; DETAILED DESCRIPTION
[0011] The filling machine according to the present application will be further described in detail in combination with the drawings and embodiments: Example 1: As shown in Figure 1 , 2 The filling machine of the present application is realized as shown in the drawings, comprising a material conveying pipe 1 with a material inlet 102, a plurality of valves 2 arranged on the conveying pipe 1 and perpendicular to the conveying pipe 1, which is characterized in that the valve 2 comprises a valve seat 202 with an axial hole 201 perpendicular to the conveying pipe 1 arranged on the upper part of the horizontally arranged conveying pipe 1, a valve core 204 driven by a power 203 (cylinder) arranged on the valve seat 202 to move up and down along the axial hole 201, a valve port 205 arranged on the lower part of the conveying pipe 1, the valve port 205 is opposite to the valve core 204, the valve port 205 is a tubular hole, a sealing structure 206 (a sealing ring arranged on the side wall groove of the valve core 204) is arranged between the valve core 204 and the axial hole 201, and the end of the valve core 204 is a columnar object 207 (cylindrical) matched with the tubular hole of the valve port 205. The valve core 204 is driven by the power 203 to penetrate into or away from the valve port 205.
[0012] Preferably, the axial hole 201 of the valve seat 202 extends into the upper part of the inner cavity of the conveying pipe 1. The axial hole 201 of the valve seat 202 extends into the upper part of the inner cavity of the conveying pipe 1, which ensures that the columnar object 207 suspended in the inner cavity of the conveying pipe 1 does not shake and can be accurately inserted into the valve port 205.
[0013] Preferably, the port 208 of the valve port 205 located in the inner cavity of the conveying pipe 1 is trumpet-shaped, and the root 209 of the matched columnar object 207 is circular truncated cone-shaped, and the circular truncated cone-shaped root 209 is a sealing pad. By using the trumpet-shaped port 208 matched with the circular truncated cone-shaped root 209, even if the diameter of the columnar object 207 is smaller than the diameter of the hole of the valve port 205, the valve port 205 can be closed by the sealing effect of the sealing pad of the root 209, at the same time, even if there are solid debris on the inner wall of the hole of the valve port 205, it does not affect the smooth insertion of the columnar object 207 into the valve port 205, and after the valve port 205 is opened, the impact force of the fluid is sufficient to flush out the solid debris retained on the inner wall of the hole of the valve port 205.
[0014] In use, the material is delivered to the delivery pipe 1 at a certain delivery pressure. When filling is required, the power 203 drives the valve core 204 to move upward, the columnar body 207 at the lower end of the valve core 204 leaves the valve port 205, the material is sprayed out of the valve port 205, and the filling operation is completed. Then, the power 203 drives the valve core 204 to move downward, the columnar body 207 at the lower end of the valve core 204 is inserted into the valve port 205, and at the same time, the material remaining in the valve port 205 is brought out of the valve port 205. Since the end of the valve core 204 is the columnar body 207 matched with the pipe hole-shaped valve port 205, even if the material (such as nuts in syrup) is stuck in the valve port 205, it is also cleaned out of the valve port 205 under the action of the columnar body 207. Since the columnar body 207 is suspended in the delivery pipe 1 when the valve is opened, there is no obstacle around the columnar body 207, and the material in the delivery pipe 1 flows smoothly to the valve port 205 when the valve is opened, ensuring smooth spraying of the material.
