Description

Technical Field

[0001] This utility model relates to a powder conveying device, and more particularly to a multi-channel switching device. Background Technology

[0002] Powder materials play a vital role in industrial production, serving as indispensable raw materials for many industries. Powder processing often utilizes pipeline transportation. When multiple points need to be transported, electric butterfly valves are typically used to control the opening and closing of different pipelines to achieve multi-path switching. Some manufacturers also use mobile pipeline switching valves, such as those disclosed in Chinese Patent (CN2506828Y), for material transport switching. However, multi-path switching pipeline systems controlled by electric butterfly valves are complex when applied to multiple sets of pipelines, resulting in high manufacturing and maintenance costs. Furthermore, mobile pipeline switching valves have a limited number of ports, making it difficult to switch more than five sets of pipelines. Given these shortcomings, it is necessary to design a multi-path switching device. Utility Model Content

[0003] The purpose of this utility model is to provide a multi-channel switching device. The number of discharge pipes of this device is not limited and can be increased or decreased according to actual conditions. It also has a simple structure and low cost.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a multi-channel switching device, including a bracket, the top of the bracket having not less than two through holes, a discharge pipe colinear with the axis of the through holes installed on the bracket, multiple sensors provided on the outer side of the bracket, the sensors being opposite to the discharge pipe, and a feed pipe provided at the lower end of the bracket, the feed pipe sliding along the left and right direction of the bracket. It is worth noting that, depending on the actual situation, the number of through holes can be increased to install more discharge pipes. Theoretically, the number of discharge pipes is unlimited.

[0005] The further improvements of this utility model are as follows:

[0006] Furthermore, the lower end of the bracket is provided with a notch for the feed pipe to slide left and right. This notch can be formed by leaving the lower end of the bracket open, or it can be a notch cut from the lower end of the bracket. The diameter of the notch can be larger than the diameter of the feed pipe to facilitate the entry and exit of the feed pipe.

[0007] Furthermore, a support plate is provided on the outside of the discharge pipe, and the support plate slides along the left and right direction of the bracket.

[0008] Furthermore, the driving component is a cylinder, the fixed end of which is detachably fixed to the support plate, and the movable end of which is detachably fixed to the feed pipe.

[0009] Furthermore, the bracket is also provided with several locking holes, which are located at the bottom of the bracket.

[0010] Furthermore, the feed tube is also equipped with a rotary positioning pin, which is inserted into the locking hole to lock the feed tube.

[0011] Furthermore, the sensor is a stroke sensor.

[0012] Furthermore, the feed pipe is also equipped with a trigger rod, which is located on the outside of the feed pipe. When the trigger rod contacts the stroke sensor, the axis of the feed pipe coincides with the axis of the discharge pipe.

[0013] Furthermore, an arc-shaped contact head is provided at the top of the trigger rod.

[0014] Furthermore, the arc-shaped contact head is made of nylon.

[0015] Compared with existing technologies, this multiplexing device has the following advantages:

[0016] 1) The number of discharge pipes can be designed according to actual conditions, with no limit on the number, thus improving the applicability;

[0017] 2) The manual switching design is adopted, which avoids the extensive use of switching devices such as electric butterfly valves. This reduces costs and simplifies the design, making it suitable for low-cost solutions. Attached Figure Description

[0025] like Figures 1 to 6 As shown, a multi-channel switching device includes a bracket 1. The top of the bracket 1 has at least two through holes 101. A discharge pipe 2, coaxial with the through holes 101, is mounted on the bracket 1. Multiple sensors 3 are located on the outer side of the bracket 1, opposite to the discharge pipe 2. A feed pipe 4 is located at the lower end of the bracket 1 and slides along the left-right direction of the bracket 1. A driving component 5 is located on the outer side of the feed pipe 4, driving the feed pipe 4 to move up and down to engage or disengage with the discharge pipe 2 for raw material transport. A support plate 401 is also located on the outer side of the discharge pipe 4 and slides along the left-right direction of the bracket 1. The driving component 5 is a cylinder; the fixed end of the cylinder is detachably fixed to the support plate 401, and the movable end of the cylinder is detachably fixed to the feed pipe 4.

[0026] The lower end of the bracket 1 is provided with a notch for the feed pipe 2 to slide left and right. This notch can be formed by leaving the lower end of the bracket 1 unclosed, or it can be formed by cutting the lower end of the bracket 1. The diameter of the notch is larger than the diameter of the feed pipe 4, so as to facilitate the entry and exit of the feed pipe.

[0027] like Figure 1 , Figure 2 , Figure 3 As shown, this embodiment also includes an operating handle 6, which is located on the outside of the bracket 1. The operating handle 6 is manually operated to drive the cylinder to move up or down, so that the feed pipe 4 moves up and down to fit or separate from the discharge pipe 2 for material conveying. There are 10 discharge pipes 2. After the operator manually pushes the feed pipe 4 to slide left and right to the target discharge pipe 2, the sensor 3 at that location is triggered. The operating handle 6 drives the driving component 5 to move the feed pipe 4 upward to fit with the discharge pipe 2 for material conveying. Of course, in order to ensure the stability of the movement of the feed pipe 4, the number of driving components 5 is set to 2, which are symmetrically arranged along the pallet. In other embodiments, the driving component 5 can also be an electric push rod, a hydraulic cylinder, or a linear module, etc., linear motion components.

[0028] like Figure 4 As shown in this embodiment, in order to improve the stability and smoothness of the movement of the pallet 401, a sliding structure 402 is provided between the pallet 401 and the bracket 1. The sliding structure 402 includes a slider 403 and a guide rail 404. The slider 403 is connected to the pallet 401, and the guide rail 404 is connected to the bracket 1. The slider 403 slides along the guide rail 404. The sliding structure 402, which is composed of the common slider 403 and guide rail 404, improves the stability and smoothness of the pallet movement, and is simple to maintain and inexpensive.

[0029] like Figure 3 , Figure 5As shown in this embodiment, in order to ensure the stability of the feed pipe 4 and the discharge pipe 2 when they are connected, the bracket 1 is also provided with a number of locking holes 102. The locking holes 102 are located at the bottom of the bracket 1. The feed pipe 4 is also provided with a rotating positioning pin 405. When the operator manually pushes the feed pipe 4 to slide left and right to the target discharge pipe 2, the operator operates the rotating positioning pin 405 to insert into the locking hole 101 to lock the feed pipe 4. At this time, the axes of the feed pipe 4 and the discharge pipe 2 are collinear, ensuring that the feed pipe 4 remains stable and does not shake when the raw material is conveyed, thus preventing the raw material from leaking out.

[0030] It is worth noting that, such as Figure 3 As shown, in this embodiment, in order to improve the sealing effect, a sealing gasket 201 is provided at the inlet of the discharge pipe 2. When the feed pipe 4 and the discharge pipe 2 are connected and fitted together, the sealing gasket 201 can seal the contact surface between the two to prevent the raw material from leaking out. Of course, in other embodiments, a sealing gasket 201 is provided at the outlet of the feed pipe 401 to seal the contact surface between the feed pipe 4 and the discharge pipe 2.

[0031] like Figure 1 , Figure 6 As shown, in this embodiment, the sensor 3 is a stroke sensor, which is characterized by its low cost and simple control system. Of course, engineers can choose other types of sensors, such as distance sensors or displacement sensors, depending on the required precision. To accommodate the stroke sensor, a trigger rod 406 is provided on the feed pipe 4. The trigger rod 406 is located on the outside of the feed pipe 4. By adjusting the position of the trigger rod 406 on the outside of the feed pipe 4, when the trigger rod 406 contacts the stroke sensor, the axis of the feed pipe 4 coincides with the axis of the discharge pipe 2. This ensures that the feed pipe 4 and the discharge pipe 2 are aligned, preventing raw material leakage.

[0032] The trigger rod 406 is provided with an arc-shaped contact head 407 at the top, and the arc-shaped contact head 407 is made of nylon. This ensures that the trigger rod 406 can make smooth contact with the stroke sensor, and also protects the stroke sensor from failure due to long-term impact.

[0033] In this embodiment, during operation, when the operator manually pushes the feed pipe 4 to slide left and right, the support plate 401 drives the slider 403 to slide along the guide rail 404, which in turn drives the feed pipe 4 to slide along the bracket 1. When it reaches the target discharge pipe 2, the trigger rod 406 on the feed pipe 4 contacts the sensor 3 at that location. At this time, the feed pipe 4 and the discharge pipe 2 are facing each other. The operator operates to rotate the positioning pin 405 into the locking hole 102 to lock the feed pipe 4. Subsequently, the operator operates the handle 6, and the control system (not shown in the figure) controls the cylinder to drive the feed pipe 4 to fit and connect with the discharge pipe 2, and the feeding system (not shown in the figure) can then carry out the raw material conveying operation. This device can switch different discharge pipes 2 for raw material conveying according to actual needs, and the number of discharge pipes 2 is unlimited, meeting the needs of various working conditions.

[0034] This utility model is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort shall fall within the protection scope of this utility model.
