Description

Technical Field

[0001] The utility model relates to the technical field of blanking devices, and more specifically, to a blanking control valve modification device. Background Art

[0002] In the polyester chip unloading control valve system on the existing biaxially oriented polyester film production line, the unloading flap valve is commonly used. For example, the German Bruckner biaxially oriented film production line uses a flap valve to discharge the material into the extruder by gravity. Since the valve body surface of the flap valve is flat, if the chip particles are uneven in size, the angle is not correct, or the particles are stuck and cannot be crushed apart in time, it is easy to cause material jamming and blockage, resulting in material unloading fluctuations, which will directly affect the production of the film.

[0003] The production equipment of many excellent biaxially oriented film production line companies, including Bruckner in Germany, are equipped with unloading flap valves in the unloading system. The main problems of the existing unloading control valve system are as follows:

[0004] First, large raw material particles can easily cause material jams and blockages. Second, wet, cohesive raw material particles can easily cause material jams and blockages. Third, during the opening and closing stages of material discharge, the discharge valve can easily become lodged by raw material particles trapped in the valve gap, preventing it from opening or closing, or even becoming stuck. These problems can repeatedly cause fluctuations in material discharge and lead to downtime, resulting in significant losses in film production. Utility Model Content

[0005] (1) Technical issues to be resolved

[0006] The technical problem to be solved by the utility model is that the existing discharge valve is prone to blocking and jamming, which in turn causes discharge fluctuations and leads to machine downtime, causing huge losses to film production.

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0017] (3) Beneficial effects

[0018] The above technical solution of the present utility model has at least the following advantages:

[0019] This utility model removes the standard gate valve that comes with the original manufacturer and replaces it with a pneumatic ball valve.

Even large particles can be crushed directly, breaking large particles into smaller ones for smoother material discharge. This utility model effectively improves equipment reliability, making production equipment safer to operate, and reduces equipment failure rates, bringing greater economic benefits to the company.

[0031] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate relative importance or the number of technical features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined. The following is a more detailed description of the specific implementation of this utility model in conjunction with specific embodiments:

[0032] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a material discharge control valve modification device, comprising a silo 1, a discharge pipe 2, a pneumatic ball valve 3, and a hopper 4. The silo 1 is used to store materials; the discharge pipe 2 is connected to the outlet of the silo 1; the pneumatic ball valve 3 is connected to the outlet of the discharge pipe 2; and the hopper 4 is connected to the outlet of the pneumatic ball valve 3. The pneumatic ball valve 3 includes a valve body 31, a spherical valve core 32, a rotating shaft 33, and an air pump 34. The valve body 31 has a receiving chamber, and the spherical valve core 32 is accommodated in the receiving chamber. One end of the rotating shaft 33 is connected to the output end of the air pump 34, and the other end of the rotating shaft 33 is connected to the spherical valve core 32. Specifically, the silo 1 is used to store polyester chips. The diameter of the discharge pipe 2 can be selected according to actual usage requirements.

[0033] The utility model removes the original ordinary gate valve and replaces it with a pneumatic ball valve 3. When the material is stuck, the air pump 34 can be activated to drive the ball valve core 32 to rotate, effectively crushing the particles that are stuck together due to excessive moisture in the material. Even large particles can be directly crushed. After resetting, smooth material discharge is achieved.

[0034] The discharge pipe 2 is welded with high-quality steel throughout and has excellent sealing performance. The discharge pipe 2 is cut and transformed into a first pipe body 21 and a second pipe body 22, and is fixed with a pipe connection lock 23 to facilitate the subsequent disassembly of the discharge control valve.

[0035] As an optional implementation of this embodiment, the spherical valve core 32 is provided with a discharge hole 321. The diameter of the discharge hole 321 is no less than the inner diameter of the discharge pipe 2. During discharge, the discharge hole 311 in the valve body 31 is coaxial with the discharge port 321 in the spherical valve core 32. This through-hole allows for material discharge. If material becomes stuck, the air pump 34 can be activated to rotate the spherical valve core 32 to an appropriate angle to crush the material.

[0036] As one of the optional implementations of this embodiment, the feeding pipe 2 includes a first pipe body 21, a second pipe body 22, and a pipe connection lock 23. The first pipe body 21 is connected to the silo 1, the second pipe body 22 is connected to the pneumatic ball valve 3, and the pipe connection lock 23 seals the connection between the first pipe body 21 and the second pipe body 22. Specifically, the number of pipe bodies can be determined based on the required pipe length of the part to be modified. Multiple pipe bodies can be selected and connected in sequence through the pipe connection lock 23 to form a feeding pipe 2 of sufficient length, thereby realizing the modification of the feeding device without changing the existing equipment.

[0037] As one of the optional implementations of this embodiment, the pipe connection lock 23 includes a first semicircular pipe clamp 231, a second semicircular pipe clamp 232, and a fastener 233. The first semicircular pipe clamp 231 and the second semicircular pipe clamp 232 are flipped and connected. The first semicircular pipe clamp 231 and the second semicircular pipe clamp 232 are each provided with a mounting groove 234 for accommodating the pipe end ring of the discharge pipe 2. The fastener 233 fastens the first semicircular pipe clamp 231 and the second semicircular pipe clamp 232. The fastener 233 is specifically a screw, bolt, etc. When the first semicircular pipe clamp 231 and the second semicircular pipe clamp 232 are flipped and opened, the pipe end rings of the first tube body 21 and the second tube body 22 can be stored in the mounting groove 234. Then, the first semicircular pipe clamp 231 and the second semicircular pipe clamp 232 are closed and locked with the fastener 233, thereby achieving the connection between the first tube body 21 and the second tube body 22.

[0038] As an optional implementation of this embodiment, the pipe connection lock 23 further includes a sealing ring, which is provided at the interface between the first tube body 231 and the second tube body 232. The sealing ring is preferably a rubber ring, which can improve the sealing performance of the connection between the first tube body 231 and the second tube body 232, thereby improving the airtightness and watertightness of the pipe.

[0039] As one of the optional implementations of this embodiment, the pneumatic ball valve 3 is sealed and connected to the discharge pipe 2 through a flange.

[0040] As one of the optional implementations of this embodiment, the pneumatic ball valve 3 and the hopper 4 are sealed and connected via a flange.

[0041] As one of the optional implementations of this embodiment, the hopper 4 is a conical hopper.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
