Description

Technical Field

[0001] The utility model relates to the technical field of powder packaging, in particular to a precise control discharging device. Background Art

[0002] In the powder industry, powder processing generally requires discharge and packaging. Using a butterfly valve for discharge is a common method in this process. The finished powder packaging requires precise weight, typically accurate to 20 grams, placing high demands on powder discharge equipment.

[0003] The current method of discharging is to control the swing amplitude of the butterfly valve (for example, repeatedly opening and closing between 10 and 12 degrees) and rely on the shaking of the powder to obtain accurate gram weight. However, this method has disadvantages:

[0004] 1. Accurate material quantity in the packaging box requires accurate material discharge, which requires adjusting the swing amplitude of the control butterfly valve according to the specific powder. However, the swing amplitude of the control butterfly valve is difficult to adjust. Different powders require different amplitudes. Adjusting to the appropriate swing amplitude is troublesome and time-consuming.

[0005] 2. During the continuous swinging process, a portion of the powder passing through the butterfly valve will be repeatedly squeezed into flakes, which cannot meet the customer's requirements for powder particles.

[0006] Therefore, in view of the shortcomings of the above scheme in actual production and implementation, it has been revised and improved. At the same time, in the spirit and concept of seeking excellence, and with the assistance of professional knowledge and experience, as well as after many ingenuity and experiments, a precise control discharge device is specially provided to solve the technical problem that it is difficult to control the swing amplitude when the butterfly valve is discharging. Utility Model Content

[0007] The purpose of the utility model is to provide a precise control discharging device, which is used to solve the technical problem that it is difficult to adjust the swing amplitude of the butterfly valve when discharging.

[0008] The technical solution of the present utility model is achieved as follows:

[0009] A precise control discharging device includes a box cover, a butterfly valve and a vibration generator. The box cover is provided with a blanking port, the top of the blanking port is provided with a connecting flange, the butterfly valve is located on the top of the connecting flange and is connected to the connecting flange, and the vibration generator is fixed on the butterfly valve.

[0010] As a preferred embodiment, the connecting flange includes a columnar blanking channel, and the columnar blanking channel passes through the blanking opening downward in the longitudinal direction.

[0011] The columnar blanking channel can enhance the sealing performance and prevent powder from floating out.

[0012] As a preferred embodiment, the edge of the box cover is provided with a cover eave inclined downward.

[0013] As a preferred embodiment, the vibration generator is fixed on the butterfly valve by using a fixer.

[0014] As a preferred embodiment, the fixture includes a top fixing seat, a bottom fixing seat, and connecting bolts. The vibration generator is located on top of the top fixing seat and is fixedly connected to the top fixing seat. The connecting bolts pass through the vibration generator, the top fixing member, and the bottom fixing member in sequence to fix the fixture to the butterfly valve. A specific and feasible method for fixing the vibration generator to the butterfly valve is provided.

[0015] As a preferred embodiment, it also includes a PLC, which is communicatively connected with the butterfly valve and the vibration generator. The PLC uses a three-position five-way solenoid valve to accurately control the opening angle of the butterfly valve.

[0016] This solution mainly changes the control requirements through novel hardware design, from controlling the swing amplitude to controlling the vibration generator. Controlling the swing amplitude and setting the maximum and minimum amplitudes require adjustment, which takes a long time and is very troublesome. Controlling the vibration generator is much easier, saves time and effort, and controls the material more accurately, with excellent applicability.

[0017] This solution is used in conjunction with a PLC control program. A three-position, five-way solenoid valve precisely controls the opening angle of the butterfly valve. At the beginning of packaging, the butterfly valve is opened to its maximum angle. When the box is nearly full, the angle is adjusted to the minimum gap. A vibration generator is installed on the butterfly valve. During the fine discharge stage, vibration can cause a small amount of powder to flow into the packaging box. This solution is simple to operate, does not require precise debugging, and avoids the situation where the butterfly valve repeatedly swings and causes solidified particles. It also has better actual measurement and control accuracy.

[0018] The beneficial effects of the utility model are:

[0019] This solution changes the control requirements through design, from controlling the swing amplitude to controlling the vibration generator. It is simple to debug, saves time and effort, and is highly practical. In addition, this method avoids the situation where the powder passing through the butterfly valve is repeatedly squeezed into flakes. The discharge is also more precise and controllable, solving the current problem of the butterfly valve being difficult to control the swing amplitude when discharging and the powder being easily pressed into flakes.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0030] In addition, the terms "first," "second," and so on, used in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of these features.

[0031] In the description of the embodiments, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct connections, connections through an intermediary medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on their specific circumstances.

[0032] like Figures 1 to 5 As shown, a precise control discharging device includes a box cover 3, a butterfly valve 2 and a vibration generator 1. A blanking port 9 is provided on the box cover 3, a connecting flange 4 is provided at the top of the blanking port 9, the butterfly valve 2 is located at the top of the connecting flange 4 and is connected to the connecting flange 4, and the vibration generator 1 is fixed on the butterfly valve 2.

[0033] The connecting flange 4 includes a columnar blanking channel 11 , which passes through the blanking opening 9 downward in the longitudinal direction.

[0034] The columnar blanking channel 11 can enhance the sealing performance and prevent powder from floating out.

[0035] The edge of the box cover 3 is provided with a cover eave 10 that is inclined downward.

[0036] The vibration generator 1 is fixed to the butterfly valve 2 by a fixer 5 .

[0037] The holder 5 includes a top fixing seat 6, a bottom fixing seat 7 and a connecting bolt 8. The vibration generator 1 is located on the top of the top fixing seat 6 and is fixedly connected to the top fixing seat 6. The connecting bolt 8 passes through the vibration generator 1, the top fixing piece, and the bottom fixing piece in sequence and fixes the holder 5 to the butterfly valve 2. A specific and feasible method of fixing the vibration generator 1 to the butterfly valve 2 is given.

[0038] It also includes a PLC, which is communicated with the butterfly valve 2 and the vibration generator 1. The PLC uses a three-position five-way solenoid valve to accurately control the opening angle of the butterfly valve 2.

[0039] Figure 2 This is a schematic diagram of the structure of the present solution without the butterfly valve 2, so as to clearly show the structure of the retainer 5 and the connecting flange 4; Figure 3 The figure shows the specific structure of the holder 5 and the connection relationship between the holder 5 and the vibration generator 1; Figure 4 The structure of the box cover 3 (and the connecting flange 4) is shown from a bottom perspective.

[0040] This solution mainly changes the control requirements through novel hardware design, from controlling the swing amplitude to controlling the vibration generator 1. Controlling the swing amplitude, the setting of the maximum amplitude and the minimum amplitude requires adjustment, which takes a long time and is very troublesome. Controlling the vibration generator 1 is much easier, saving time and effort, and the material control is more accurate, and the applicability is very good.

[0041] This solution is used in conjunction with the PLC control program. The opening angle of the butterfly valve is accurately controlled by a three-position five-way solenoid valve. When packing begins, the opening angle of the butterfly valve is opened to a maximum of 90 degrees. When the box is nearly full, the opening angle of the butterfly valve is adjusted to the minimum gap (5 degrees or any angle, depending on the actual situation). A vibration generator 1 is installed on the butterfly valve 2. During the fine discharging stage, a small amount of powder can be made to flow into the packaging box 12 through vibration. This solution is simple to operate, does not require precise debugging, and avoids the situation where the butterfly valve repeatedly swings to cause solidified particles. In addition, the measured gram weight is more accurate than before, and can be within 5 grams, with better material control accuracy. Figure 6 What is shown is a schematic diagram of the packaging box, that is, a diagram of the usage status, which can be used as a reference.

[0042] The beneficial effects of the utility model are:

[0043] This solution changes the control requirements through design, from controlling the swing amplitude to controlling the vibration generator. It is simple to debug, saves time and effort, and is highly practical. In addition, this method avoids the situation where the powder passing through the butterfly valve is repeatedly squeezed into flakes. The discharge is also more precise and controllable, solving the current problem of the butterfly valve being difficult to control the swing amplitude when discharging and the powder being easily pressed into flakes.

[0044] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention. In addition, the technical solutions of the various embodiments may be combined with each other, but this must be based on the fact that they can be implemented by a person of ordinary skill in the art. If the combination of technical solutions is inconsistent or cannot be implemented, it shall be deemed that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.
