[0004] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a positioning sandwich valve body device to achieve accurate positioning of the core material of a single product.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a positioning sandwich valve body device, comprising: a valve body assembly and a drive assembly, wherein the valve body assembly includes a valve body, a flow-stopping valve stem, and a back-suction valve stem; the valve body is provided with a core material channel in a direction perpendicular to the ground; the valve body is provided with a main valve chamber and a back-suction valve chamber in a direction forming an angle with the axis of the core material channel; the main valve chamber and the back-suction valve chamber are arranged sequentially along the core material flow direction and are both connected to the core material channel; the flow-stopping valve stem is disposed in the main valve chamber and is connected to the drive assembly. The sidewall of the valve cavity is rotatably fitted and has a feed hole that passes through the flow-stopping valve rod. The back-suction valve rod is located inside the back-suction valve cavity and is slidably connected to the back-suction valve cavity. The drive assembly is connected to the flow-stopping valve rod and the back-suction valve rod respectively, and is used to drive the flow-stopping valve rod to rotate in the main valve body and drive the back-suction valve rod to slide in the back-suction valve cavity. The rotation of the flow-stopping valve rod is used to open or close the feed hole to the core material channel, and the sliding of the back-suction valve rod is used to suck the core material in or squeeze it out of the back-suction valve cavity.

[0006] Furthermore, the axes of the main valve chamber and the back suction valve chamber are perpendicular to the axis of the core material channel.

[0007] Furthermore, the main valve chamber extends through the valve body and is equipped with a sealing element, which is located between the side walls at both ends of the main valve chamber and the flow-stopping valve stem.

[0008] Furthermore, the drive assembly includes a mounting base, a first drive member, and a second drive member. Both the first drive member and the second drive member are connected to the mounting base. The first drive member is connected to the suction valve rod and is used to drive the suction valve rod to slide back and forth in the suction valve chamber. The second drive member is connected to the flow-stopping valve rod and is used to drive the flow-stopping valve rod to rotate relative to the main valve chamber.

[0009] Furthermore, the mounting base includes a left side plate, a right side plate, and a fixing post.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1-6 As shown, this utility model proposes a positioning sandwich valve body device including a valve body assembly 1 and a drive assembly 2. The valve body assembly includes a valve body 4, a flow-stopping valve stem 5 and a back suction valve stem 6. The valve body 4 is provided with a core material channel in a direction perpendicular to the ground. The valve body 4 is provided with a main valve chamber 9 and a back suction valve chamber 10 in a direction that forms an angle with the axis of the core material channel. The main valve chamber 9 and the back suction valve chamber 10 are arranged sequentially along the core material flow direction and are all connected to the core material channel.

[0026] The flow interruption valve stem 5 is located in the main valve chamber 9 and is rotatably engaged with the side wall of the main valve chamber 9. It is provided with a material conveying hole 12 that passes through the flow interruption valve stem 5. The back suction valve stem 6 is located in the back suction valve chamber 10 and is slidably connected to the back suction valve chamber 10.

[0027] The drive assembly 2 is connected to the flow cut-off valve rod 5 and the back suction valve rod 6 respectively, and is used to drive the flow cut-off valve rod 5 to rotate in the main valve body 9 and drive the back suction valve rod 6 to slide in the back suction valve cavity 10. The rotation of the flow cut-off valve rod 5 is used to connect or close the core material channel of the feed hole 12, and the sliding of the back suction valve rod 6 is used to suck the core material into or squeeze it out of the back suction valve cavity 10.

[0028] It is understood that the two ends of the core material channel are the inlet 8 and the outlet 11, respectively. The inlet 8 and the outlet 11 are connected to form the core material channel. The main valve chamber 9 and the back suction valve chamber 10 are located between the inlet 8 and the outlet 11, and both are connected to the core material channel.

[0029] It is understandable that the core material enters the core material channel from the feed inlet 8. When the flow cut-off valve rod 5 rotates to the point where the feed hole 12 connects to the core material channel, the core material flows out from the discharge port 11 after passing through the core material channel. When the flow cut-off valve rod 5 rotates to the point where the feed hole 12 closes the core material channel, that is, when the feed hole 12 does not coincide with the core material channel, the core material cannot flow in.

[0030] In this embodiment, the axes of the main valve chamber 9 and the back suction valve chamber 10 are both perpendicular to the axis of the core material channel.

[0031] It is understandable that when core material needs to be injected, the flow cut-off valve rod 5 is rotated until the feed hole 12 is connected to the core material channel. The core material flows through the core material channel to the outlet 11 for filling. When the predetermined amount is filled, the back suction valve rod 6 is driven to slide away from the valve body 4 in the back suction valve chamber 10, so that the air pressure in the back suction valve chamber 10 is lower than the external air pressure, so as to generate negative pressure to suck the remaining core material in the core material channel into the back suction valve chamber 10. This avoids the core material from flowing out of the outlet 11 under the action of gravity after the predetermined amount is filled, thus affecting the filling accuracy of a single product and ensuring that the core material filling amount of a single product is consistent.

[0032] In this embodiment, the valve body assembly 1 and the drive assembly 2 are connected by a connecting post 3.

[0033] Furthermore, the main valve chamber 9 extends through the valve body 4, and a sealing element 7 is provided inside it. The sealing element 7 is located between the side walls at both ends of the main valve chamber 9 and the shut-off valve stem 5.

[0034] It is understandable that the seal 7 is used to prevent the core material from flowing out, and does not affect the rotation of the shut-off valve stem 5 relative to the main valve chamber 9.

[0035] Furthermore, the drive assembly 2 includes a mounting base 13, a first drive member, and a second drive member. Both the first drive member and the second drive member are connected to the mounting base 13. The first drive member is connected to the suction valve rod 6 and is used to drive the suction valve rod 6 to slide back and forth in the suction valve chamber 10. The second drive member is connected to the flow-stopping valve rod 5 and is used to drive the flow-stopping valve rod 5 to rotate relative to the main valve chamber 9.

[0036] Furthermore, the mounting base 13 includes a left side plate 23, a right side plate 24, and a fixing post 26. The fixing post 26 is located between the left side plate 23 and the right side plate 24, and its two ends are respectively connected to the left side plate 23 and the right side plate 24. The first driving member and the second driving member are both connected to the right side plate 24 and pass through the right side plate 24. The back suction valve rod 6 and the flow cut-off valve rod 5 both pass through the left side plate 24 and are respectively connected to the first driving member and the second driving member.

[0037] Furthermore, the first driving component includes a lead screw 14, a slider 15, and a first motor 19. The lead screw 14 is located between the left side plate 23 and the right side plate 24, and its two ends are rotatably connected to the left side plate 23 and the right side plate 24, respectively. The first motor 19 is connected to the right side plate 24, and its output shaft is connected to the end of the lead screw 14 near the right side plate 24. The slider 15 is threadedly engaged with the lead screw 15 and connected to the suction valve rod 6.

[0038] It can be understood that the first motor 19 drives the lead screw 14 to rotate in both directions, causing the slider 15, which is threadedly engaged with the lead screw 14, to slide on the lead screw 14, thereby driving the suction valve rod 6 to move together, so as to realize the reciprocating sliding of the suction valve rod 6 in the suction valve cavity 10.

[0039] Furthermore, the first driving component also includes a connecting block 16, through which the slider 15 and the suction valve rod 6 are connected.

[0040] Furthermore, the first driving component also includes a motor mounting base 18, through which the first motor 19 is connected to the right side plate 24.

[0041] It is understood that the first motor 19 is connected to the lead screw 14 through the first coupling 17. This can be either the lead screw 14 passing through the right side plate 24 and then connecting to the first coupling 17, or the first coupling 17 passing through the right side plate 24 and extending to the space between the left side plate 23 and the right side plate 24 and connecting to the lead screw 14.

[0042] In this embodiment, a through hole is provided on the right side plate 24, and a bearing fixing seat 25 is provided in the through hole. A bearing is provided in the bearing fixing seat 25. The lead screw 14 is inserted into the bearing to realize the rotatable connection with the right side plate 24. After the lead screw 14 is inserted into the bearing, it extends to the side away from the right side plate 24 to connect with the first coupling 17.

[0043] It is understandable that the rotatable connection between the lead screw 14 and the left side plate 23 can also be achieved by setting a bearing on the left side plate 23.

[0044] Furthermore, the second driving component includes a second coupling 21 and a second motor 22, with the second coupling 21 connected to the flow-stopping valve stem 5 and the output shaft of the second motor 22, respectively.

[0045] Furthermore, the second driving component also includes a clamp 20, which is disposed on the left side plate 23 and is used to limit the axial displacement of the shut-off valve stem 5.

[0046] In this embodiment, the clamp 20 is disposed on the left side plate 23 and sleeved on the flow cut-off valve stem 5, thereby restricting the flow cut-off valve stem 5 from moving along its axial direction. That is, the flow cut-off valve stem 5 only rotates relative to the main valve chamber 9, and does not slide relative to the main valve chamber 9.

[0047] The working principle of this utility model is as follows: Initially, the core material enters from the inlet 8. At this time, the flow cut-off valve rod 5 rotates until the feed hole 12 coincides with the core material channel. After the core material enters from the inlet 8, it flows through the feed hole 12 to the outlet 11 to fill the product with core material. When the product is filled to the predetermined amount and filling needs to be stopped, the flow cut-off valve rod 5 rotates until the feed hole 12 and the core material channel form an angle to close the core material channel. After closure, the core material that has flowed through the feed hole 12, that is, the core material in the core material channel below the main valve chamber 9, will still drip down under the action of gravity. Since the product has already been filled with the predetermined amount of core material, if more core material is dripped into the product, it will cause the core material filling to exceed the standard and will also affect the appearance of the product. At this time, the first motor 19 drives the back suction valve rod 6 to slide away from the valve body 4 through the transmission of the lead screw 14, which increases the space of the back suction valve chamber 10 and generates negative pressure in the back suction valve chamber 10. This draws the core material located in the core material channel into the back suction valve chamber 10, preventing it from dripping onto the product, thereby achieving precise filling and positioning of a single product.

[0048] When the next product needs to be filled, the second motor 22 drives the flow cut-off valve rod 5 to rotate again until the feed hole 12 coincides with the core material channel. At the same time, the first motor 19 also drives the back suction valve rod 6 to slide closer to the valve body 4, thereby squeezing out the core material in the back suction valve chamber 10 and filling it into the next product from the discharge port 11.

[0049] As can be seen from the above embodiments, by setting a back suction valve rod and a back suction valve chamber, this utility model can use pressure difference to draw back the excess core material retained in the core material channel into the back suction valve chamber after a single product has completed the predetermined filling amount. This prevents the retained core material from continuing to fall into the filled product under the action of gravity, thereby achieving precise positioning of the filling of a single product and ensuring the consistency of the filling amount of a single product.

[0050] The present invention is not limited to the embodiments described in the specific implementation. Other implementation methods derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of the technical innovation of the present invention.
