Description

Technical Field

[0001] This utility model relates to the field of filling device technology, specifically to an adjustable flow rate weighing and filling device. Background Technology

[0002] Utility model patent CN220951157U discloses a filling and weighing machine. The machine has a weighing platform mounted on its top, and a weighing frame assembly mounted on top of the platform. The frame assembly includes a frame plate with two vertical plates symmetrically connected to its bottom. A through groove is formed on the surface of the frame plate, and a conveying assembly is installed inside the groove. The conveying assembly includes two guide plates, and conveying components are rotatably mounted on the inner wall of each guide plate. This utility model uses the output end of a hydraulic cylinder to push the horizontal plate, causing the conveyor rollers to lift the ton containers. Simultaneously, a drive motor starts, causing a pinion and a large gear to engage and control the rotation of the conveyor belt, which in turn drives the conveyor rollers to rotate. This facilitates the displacement and transport of the ton containers, allowing them to be quickly moved onto a transport vehicle, reducing the workload of workers and improving work efficiency to some extent.

[0003] However, the device has some shortcomings in use. It is not easy to adjust the discharge flow rate. If the flow rate is too high, the liquid in the container is easily impacted and overflows. At the same time, the device does not change when changing containers after filling, which affects the filling efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable flow rate weighing and filling device, which solves the problems of inconvenient adjustment of the discharge flow rate, excessive flow rate causing liquid in the container to be easily impacted and overflowed, and the inability to change containers after filling, thus affecting filling efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable flow weighing and filling device, comprising a base, a conversion mechanism on the base, a tray on the conversion mechanism, a weighing device on the tray, a bracket fixedly connected to the upper end of the base, a feeding hopper fixedly connected to the surface of the bracket, a discharge pipe fixedly connected to the inside of the feeding hopper, and an adjustment mechanism on the discharge pipe.

[0006] Preferably, the conversion mechanism includes a motor. The motor is fixedly mounted on the lower end of the base. The motor's shaft passes through the base and is rotatably connected to it. The motor's shaft is fixedly connected to a pallet. A guide rod is fixedly connected to the lower end of the pallet. A cylinder is slidably connected to the outer side of the guide rod. A spring is provided on the outer side of the guide rod. An insert block is fixedly connected to the lower end of the cylinder. The insert block is slidably connected to the base. The motor drives the pallet to rotate, thereby changing the weighing device's position. The spring acts on the cylinder, causing the insert block and the slot on the base to engage and limit the pallet's position. This ensures accurate positioning after the device changes positions, making the filling process more efficient.

[0007] Preferably, a support is fixedly connected to the upper end of the base, and the support and the tray are slidably connected. By providing the support, the tray is given auxiliary support.

[0008] Preferably, one end of the spring is fixedly connected to the support plate, and the other end of the spring is fixedly connected to the cylinder. By setting the spring, the cylinder is elastically pressed down.

[0009] Preferably, the adjusting mechanism includes a support plate, which is fixedly connected inside the discharge pipe. A slide rod is fixedly connected to the lower end of the support plate, and a plug is slidably connected to the outer side of the slide rod. A compression spring is provided on the outer side of the slide rod, with one end of the compression spring fixedly connected to the support plate and the other end fixedly connected to the plug. A retaining ring is fixedly connected inside the discharge pipe, and the retaining ring and the plug are slidably connected. A sliding pin is fixedly connected to the surface of the plug, and the sliding pin is slidably connected to the discharge pipe. A threaded ring is threadedly connected to the outer side of the discharge pipe. By rotating the threaded ring and the discharge pipe, the sliding pin causes the plug to move, and the gap between the plug and the retaining ring changes, thereby changing the flow rate of the discharge pipe and preventing overflow from the container due to excessive filling speed if the container is too small.

[0010] Preferably, a retaining sleeve is fixedly connected to the outer side of the sliding pin, and the retaining sleeve is slidably connected to the discharge pipe. By setting the retaining sleeve, the discharge pipe is sealed off.

[0011] Preferably, a protrusion is fixedly connected to the lower end of the sliding pin, and the protrusion is slidably connected to the threaded ring. By providing the protrusion, the friction between the sliding pin and the threaded ring is reduced.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a motor to drive the pallet to rotate, thereby enabling the weighing device to switch positions. Furthermore, a spring acts on the cylinder, causing the insertion block and the slot on the base to engage and limit the pallet. This ensures accurate positioning after the device switches positions, resulting in more efficient filling.

[0014] 2. This utility model uses the rotating screw ring and the discharge pipe to make a threaded movement, which causes the sliding pin to drive the plug to move and the gap between the plug and the retaining ring to change, thereby changing the flow rate of the discharge pipe and preventing the container from overflowing due to excessive filling speed when the container is too small.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-2 An adjustable flow weighing and filling device includes a base 1, a conversion mechanism 2 on the base 1, a tray 3 on the conversion mechanism 2, a weighing device 4 on the tray 3, a bracket 5 fixedly connected to the upper end of the base 1, a feeding hopper 6 fixedly connected to the surface of the bracket 5, a discharge pipe 7 fixedly connected inside the feeding hopper 6, and an adjustment mechanism 8 on the discharge pipe 7.

[0022] Please see Figures 1-2The conversion mechanism 2 includes a motor 21. The motor 21 is fixedly installed at the lower end of the base 1. The rotating shaft of the motor 21 passes through the base 1 and is rotatably connected to the base 1. The rotating shaft of the motor 21 is fixedly connected to the support plate 3. A support 22 is fixedly connected to the upper end of the base 1. The support 22 is slidably connected to the support plate 3. The support 22 provides auxiliary support for the support plate 3. A guide rod 23 is fixedly connected to the lower end of the support plate 3. A cylinder 24 is slidably connected to the outer side of the guide rod 23. A spring 25 is provided on the outer side of the guide rod 23. One end of the spring 25 is connected to the support plate. 3. Fixed connection: The other end of the spring 25 is fixedly connected to the cylinder 24. By setting the spring 25, the cylinder 24 is elastically pressed down. The lower end of the cylinder 24 is fixedly connected to the insert block 26. The insert block 26 is slidably connected to the base 1. The motor 21 drives the tray 3 to rotate, thereby causing the weighing device 4 to change positions. The spring 25 acts on the cylinder 24, thereby causing the insert block 26 and the slot on the base 1 to cooperate to limit the tray 3. This makes the device accurately positioned after changing positions, and makes the filling of the device more efficient.

[0023] Please see Figure 1 , Figure 3 , Figure 4 The adjusting mechanism 8 includes a support plate 81. The support plate 81 is fixedly connected inside the discharge pipe 7. A slide rod 82 is fixedly connected to the lower end of the support plate 81. A plug 83 is slidably connected to the outer side of the slide rod 82. A compression spring 84 is provided on the outer side of the slide rod 82. One end of the compression spring 84 is fixedly connected to the support plate 81, and the other end of the compression spring 84 is fixedly connected to the plug 83. A retaining ring 85 is fixedly connected inside the discharge pipe 7. The retaining ring 85 and the plug 83 are slidably connected. A sliding pin 86 is fixedly connected to the surface of the plug 83. The sliding pin 86 is slidably connected to the discharge pipe 7. A stop is fixedly connected to the outer side of the sliding pin 86. The sleeve 87, the retaining sleeve 87 and the discharge pipe 7 are slidably connected. By setting the retaining sleeve 87, the discharge pipe 7 is closed. The outer side of the discharge pipe 7 is connected to the threaded ring 88. The lower end of the sliding pin 86 is fixedly connected to the protrusion 89. The protrusion 89 and the threaded ring 88 are slidably connected. By setting the protrusion 89, the friction between the sliding pin 86 and the threaded ring 88 is reduced. By rotating the threaded ring 88 and the discharge pipe 7, the sliding pin 86 drives the plug 83 to move and the gap between it and the retaining ring 85 changes. This changes the flow rate of the discharge pipe 7 and prevents the container from overflowing from the container due to the excessively fast filling speed.

[0024] The specific implementation process of this utility model is as follows: In use, the container is placed on the weighing device 4, and the motor 21 is started. The motor 21 drives the pallet 3 to rotate, thereby causing the weighing device 4 to change positions. During this process, the rotation of the cylinder 24 causes the insert 26 and the slot on the base 1 to misalign, thus causing the cylinder 24 to move upwards. The upward movement of the cylinder 24 compresses the spring 25 until the cylinder 24 rotates to the point where the insert 26 corresponds to the next slot position. The spring 25 acts on the cylinder 24, thereby causing the insert 26 and the slot on the base 1 to cooperate and limit the position of the pallet 3, thus... After the device changes position, the positioning is accurate, which makes the filling more efficient. The flow rate is adjusted according to the size of the container. The screw ring 88 is manually rotated. The rotation of the screw ring 88 and the screw pipe 7 make a threaded movement, which causes the screw ring 88 to move upward. The screw ring 88 drives the sliding pin 86 to move upward. The sliding pin 86 drives the plug 83 to move, which changes the gap between the plug 83 and the retaining ring 85. This changes the flow rate of the screw pipe 7, preventing the container from overflowing due to excessive filling speed when the container is too small. Then, the solenoid valve on the feed hopper 6 is activated to control the discharge pipe 7 to discharge material.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
