Description

Technical Field

[0001] The utility model belongs to the technical field of valve islands, and particularly relates to a fast spraying valve island. Background Technique

[0002] A valve island is a control component composed of multiple electric control valves. It integrates signal input / output and signal control. Just like a control island, the valve island mechanism is generally an electro-pneumatic integrated control component. It has developed from the initial valve island with a multi-pin interface to the valve island with a field bus, and then programmable valve islands and modular islands have emerged. The combination of valve island technology and field bus technology not only ensures easy wiring of electric control valves, but also greatly simplifies the debugging, performance detection, diagnosis and maintenance of complex systems. A spraying valve island is a control component composed of multiple electric control valves, integrating various control functions required in spraying operations, such as color switching, flow control, pressure regulation, etc. The spraying valve island usually consists of multiple modules, including a control module, a solenoid valve module, a signal input / output module, etc. These modules are interconnected through internal circuits and pipelines to form a complete control system. The valve islands on the market need to be fixed one by one with a large number of screws as a whole, which is not only troublesome but also has low installation efficiency.

[0003] In the prior art, there is a multi-pin valve island with the patent publication number of CN213332546U. When the above patent is not in use, the connection head is unplugged, and then the slider is slid into the chute to drive the dust-proof plate to slide into the fixed frame to cover the circuit connection part, preventing dust from entering. It effectively realizes that the circuit connection part of the existing multi-pin valve island has a dust-proof function, and can prevent dust and other sundries from entering the circuit connection part, damaging the circuit connection part and affecting the use of the solenoid valve. However, there are still the following deficiencies in actual use: From a practical point of view, the overall installation of this valve island requires multiple screws to be fixed one by one, and the fixing steps are relatively cumbersome, reducing the installation efficiency. Moreover, this valve island is composed of multiple electric control valve components. When a fault occurs or maintenance is required, the entire electric control valve component needs to be disassembled, and the work efficiency is not high, and it is not convenient for maintenance or replacement.

[0004] Therefore, a fast spraying valve island is needed to solve the problem of relatively cumbersome fixing steps and reduced installation efficiency in the prior art. Content of the Utility Model

[0005] The purpose of the utility model is to provide a fast spraying valve island to solve the problems put forward in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A fast spraying valve island, comprising a fixing plate, a mounting mechanism, a bottom plate, a control valve body and a fixing mechanism. The mounting mechanisms are symmetrically arranged on the left and right sides of the fixing plate. The bottom plate is arranged above the fixing plate through the mounting mechanism. The fixing mechanism is arranged inside the bottom plate. The control valve body is installed above the bottom plate through the fixing mechanism.

[0007] The mounting mechanism consists of a threaded rod, a moving frame, a limiting rod, a bidirectional lead screw, a cross block, a pressing plate, a limiting column and a limiting cylinder. Grooves are symmetrically opened above the fixing plate. The threaded rod is threadedly connected to one end of the fixing plate, and a handle is fixedly connected to the end of the threaded rod away from the fixing plate. The moving frame is rotatably connected to the other end of the threaded rod.

[0008] It should be noted in the solution that the limiting rods are symmetrically and fixedly connected to one side of the moving frame, and the limiting rods are slidably connected to the fixing plate. The moving frame is slidably connected inside the groove.

[0009] Furthermore, it is worth noting that the bidirectional lead screw is rotatably connected inside the moving frame, and the back end of the bidirectional lead screw penetrates through the back of the fixing plate. A through groove adapted to the bidirectional lead screw is opened on the back of the fixing plate.

[0010] Even further, it should be noted that the cross blocks are symmetrically threadedly connected to the outside of the bidirectional lead screw, and the cross blocks are slidably connected inside the moving frame. The pressing plate is fixedly connected above the cross block. The limiting column is fixedly connected to the side of the pressing plate close to the bottom plate.

[0011] As a preferred implementation manner, the limiting cylinders are symmetrically and fixedly connected to the side of the bottom plate close to the pressing plate, and the inner shape of the limiting cylinder is adapted to the limiting column.

[0012] As a preferred implementation manner, the fixing mechanism consists of a slide bar, a connecting plate, a spring and a positioning block. A chute is opened on the back of the bottom plate. The slide bar is fixedly connected to the bottom surface of the control valve body, and the slide bar is slidably connected inside the chute. An L-shaped groove is opened on the bottom surface of the chute, and the front end of the L-shaped groove is communicated with the front of the bottom plate. The connecting plate is slidably connected inside the L-shaped groove.

[0013] As a preferred implementation manner, the spring is fixedly connected between the bottom surface of the connecting plate and the bottom surface of the L-shaped groove. The positioning block is fixedly connected above the connecting plate, and an inclined surface is arranged above the back of the positioning block. A positioning groove is opened on the bottom surface of the slide bar, and the size of the positioning groove is adapted to the positioning block.

[0014] Compared with the prior art, a fast spraying valve island provided by the present utility model at least includes the following

[0015] Beneficial effects:

[0016] (1) By means of the provided installation mechanism, valve islands of different size specifications can be installed without using screws, which simplifies the fixing steps, has a simple structure, is convenient to operate, improves the disassembly and assembly efficiency, and is beneficial to the maintenance and repair of the valve island.

Similarly, when installing the sliding bar, the sliding bar is clamped under the elastic action of the spring, which facilitates the disassembly and assembly of the sliding bar.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following further describes the present utility model in conjunction with embodiments.

[0025] Please refer to Figures 1-5 , the present utility model provides a fast spraying valve island, including a fixing plate 1, an installation mechanism 2, a bottom plate 3, a control valve body 4 and a fixing mechanism 5. The installation mechanism 2 is symmetrically arranged on the left and right sides of the fixing plate 1. The bottom plate 3 is arranged above the fixing plate 1 through the installation mechanism 2. The fixing mechanism 5 is arranged inside the bottom plate 3. The control valve body 4 is installed above the bottom plate 3 through the fixing mechanism 5.

[0026] The mounting mechanism 2 is composed of a threaded rod 202, a moving frame 203, a limiting rod 204, a bidirectional lead screw 205, a cross block 207, a pressing plate 208, a limiting column 209 and a limiting cylinder 210. Grooves 201 are symmetrically formed above the fixing plate 1. The threaded rod 202 is threadedly connected to one end of the fixing plate 1, and a handle is fixedly connected to the end of the threaded rod 202 away from the fixing plate 1. The moving frame 203 is rotatably connected to the other end of the threaded rod 202.

[0027] Further as shown in Figure 2 、 Figure 3 and Figure 4 It is worth specifically explaining that the limiting rods 204 are symmetrically and fixedly connected to one side of the moving frame 203, and the limiting rods 204 are slidably connected to the fixing plate 1. The moving frame 203 is slidably connected to the inside of the groove 201. The bidirectional lead screw 205 is rotatably connected to the inside of the moving frame 203, and the back end of the bidirectional lead screw 205 penetrates through the back of the fixing plate 1, and a through groove 206 adapted to the bidirectional lead screw 205 is formed on the back of the fixing plate 1.

[0028] Further as shown in Figure 2 、 Figure 3 and Figure 4 It is worth specifically explaining that the cross blocks 207 are symmetrically threadedly connected to the outside of the bidirectional lead screw 205, and the cross blocks 207 are slidably connected to the inside of the moving frame 203. The pressing plate 208 is fixedly connected above the cross block 207. The limiting column 209 is fixedly connected to the side of the pressing plate 208 close to the bottom plate 3.

[0029] Further as shown in Figure 2 、 Figure 3 and Figure 4 It is worth specifically explaining that the limiting cylinders 210 are symmetrically and fixedly connected to the side of the bottom plate 3 close to the pressing plate 208, and the internal shape of the limiting cylinder 210 is adapted to the limiting column 209;

[0030] By rotating the bidirectional lead screw 205 to drive the cross blocks 207 to move towards or away from each other, the distance between the pressing plates 208 is adjusted. By driving the limiting column 209 to move through the pressing plate 208, the limiting column 209 is inserted into the inside of the limiting cylinder 210, so that the bottom plate 3 can be clamped and fixed, which is convenient for installing and using the bottom plate 3 and the control valve body 4.

[0031] According to the above working process, it can be known that: through the provided mounting mechanism 2, valve islands with different size specifications can be installed, without the need to install through screws, which simplifies the fixing steps, has a simple structure, is convenient to operate, improves the disassembly and assembly efficiency, and is beneficial to the maintenance and repair of the valve island.

[0032] Further as shown in Figure 2 、Figure 4 and Figure 5 As shown in Figure 5 , it is worth specifically explaining that the fixing mechanism 5 is composed of a slide bar 501, a connecting plate 505, a spring 506 and a positioning block 507. A chute 502 is opened on the back surface of the bottom plate 3. The slide bar 501 is fixedly connected to the bottom surface of the control valve body 4, and the slide bar 501 is slidably connected to the inside of the chute 502. An L-shaped groove 504 is opened on the bottom surface of the chute 502, and the front end of the L-shaped groove 504 is communicated with the front surface of the bottom plate 3. The connecting plate 505 is slidably connected to the inside of the L-shaped groove 504.

[0033] Further, as shown in Figure 2 , Figure 4 and Figure 5 As shown in Figure 5 , it is worth specifically explaining that the spring 506 is fixedly connected between the bottom surface of the connecting plate 505 and the bottom surface of the L-shaped groove 504. The positioning block 507 is fixedly connected above the connecting plate 505, and a slope is provided above the back surface of the positioning block 507. A positioning groove 503 is opened on the bottom surface of the slide bar 501, and the positioning groove 503 is adapted to the size of the positioning block 507;

[0034] Through the slope design above the back surface of the positioning block 507, it plays a guiding role when the connecting plate 505 is docked with the slide bar 501, so that the positioning block 507 can smoothly slide into the positioning groove 503, further improving the installation accuracy and efficiency.

[0035] This solution has the following working process: When in use, first place the bottom plate 3 above the middle of the fixing plate 1, and then manually rotate the threaded rod 202. Since the limiting rod 204 is slidably connected to the fixing plate 1, the movement of the moving frame 203 following the threaded rod 202 is restricted, thereby driving the moving frame 203 to move stably in a straight line. The limiting column 209 is driven to move through the pressing plate 208, so that the limiting column 209 is inserted into the inside of the limiting cylinder 210, thereby the bottom plate 3 can be clamped and fixed, facilitating the installation and use of the bottom plate 3 and the control valve body 4; When fixing bottom plates 3 of different sizes are required, the two-way lead screw 205 can be rotated to drive the cross block 207 to move towards or away from each other, adjusting the distance between the pressing plates 208 to expand the applicable range of the device; When a certain control valve body 4 above the bottom plate 3 fails, press down the connecting plate 505 to drive the positioning block 507 to move downward, release the positioning of the slide bar 501, and the control valve body 4 can be pulled out backward to remove the control valve body 4, facilitating the replacement or repair of the control valve body 4, avoiding the disassembly of the overall valve island, and improving the maintenance efficiency.

[0036] In summary: By setting the installation mechanism 2, valve islands with different size specifications can be installed without using screws, simplifying the fixing steps, with a simple structure and convenient operation, improving the disassembly and assembly efficiency, which is beneficial to the maintenance and repair of the valve island; by setting the fixing mechanism 5, when it is necessary to maintain and repair the individual control valve body 4 in the valve island, the limiting connection between the positioning block 507 and the positioning groove 503 is released, and the control valve body 4 is pulled out from the bottom plate 3 by sliding the slide bar 501 inside the sliding groove 502, improving the working efficiency. Similarly, when installing the slide bar 501, the slide bar 501 is locked under the elastic action of the spring 506, facilitating the disassembly and assembly of the slide bar 501.
