Description

Technical Field

[0001] This invention belongs to the field of pipeline valves, specifically relating to a pipeline valve for discharging putty powder during putty powder production. Background Technology

[0002] In the production and discharge of powder materials such as putty powder, pipeline valves are the core components for controlling the flow of materials. Currently, the discharge valves widely used in the industry are mostly manual plug-in type plate valves, which mainly consist of a discharge pipe and a removable plate valve body. The discharge channel is cut off or opened by manually inserting or pulling the plate valve into the opening on the side wall of the discharge pipe. This type of traditional manual plate valve device has many inherent defects in practical applications.

[0003] The technical solution disclosed in the patent document with announcement number CN205155193U is as follows: a pipe valve for discharging putty powder, including a storage bin and a discharge pipe located at the bottom of the storage bin. The discharge pipe has a circular pipe structure and a plate valve is provided on the discharge pipe. An opening is opened on the lower side wall of the discharge pipe, and the plate valve is installed in the opening. The plate valve includes an integrally formed plate valve body, a protrusion and a handle. The handle is located on one side of the plate valve body, and the protrusion is located on the other side of the plate valve body. The central angle corresponding to the plate valve body is equal to the central angle corresponding to the opening, and the outline diameter of the plate valve body is equal to the outer diameter of the discharge pipe. The edge outline surface of the protrusion is fitted with the inner wall of the discharge pipe.

[0004] The existing technology has the following problems: In the above-mentioned device, putty powder is easy to adhere and accumulate on the discharge pipe, the inner wall of the valve body and the surface of the plate valve. Long-term use will lead to valve jamming, sealing failure, poor material discharge, and even pipeline blockage. At the same time, the opening and closing of the valve depends entirely on manual insertion and removal of the plate valve, which cannot achieve automated control, has low operating efficiency and is difficult to link with the production process. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a pipe valve for discharging putty powder during putty powder production, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides a pipe valve for discharging putty powder in putty powder production, comprising a valve body, a control box fixedly connected to the outer wall of the valve body, a valve stem rotatably connected to the inner wall of the valve body, a valve plate fixedly sleeved on the outer wall of the valve stem, and one end of the valve stem penetrating through the valve body and the control box; A full gear is fixedly sleeved on the outer wall of the valve stem. A micro motor is fixedly connected to the outer wall of the control box. A half gear and a cam are fixedly sleeved on the output shaft of the micro motor. A lifting rod slides through the upper end of the control box. A lifting plate A is fixedly connected to the bottom of the lifting rod. A lifting cylinder is fixedly connected to the upper end of the lifting rod. A rotating rod is rotatably connected to the upper side of the valve body. A scraper is fixedly connected to the lower outer wall of the rotating rod. A spiral groove is opened on the upper outer wall of the rotating rod. A round block is fixedly connected to the inner wall of the lifting cylinder. An elastic element for resetting the lifting rod is assembled at the upper end of the control box.

[0007] Preferably, the elastic element includes a connecting block and a spring A. The connecting block is fixedly sleeved on the outer wall of the lifting rod, and the spring A is fixedly connected to the bottom of the connecting block. The bottom of the spring A is fixedly connected to the control box.

[0008] Preferably, the bottom of the lifting plate A is in contact with the surface of the cam, and one side of the scraper is in contact with the inner wall of the valve body.

[0009] Preferably, the lifting cylinder is slidably connected to the outer wall of the rotating rod, and the circular block is slidably connected to the inside of the spiral groove.

[0010] Preferably, the outer wall of the control box is equipped with a striking assembly, which includes a toggle block. The toggle block is fixedly connected to one end of the valve stem located on the outside of the control box. An annular block is rotatably connected to the outer wall of the control box. A connecting rod A is hinged to the outer wall of the annular block. A moving rod is hinged to the other end of the connecting rod A. A mounting plate is fixedly connected to the end of the moving rod away from the connecting rod A. A rubber striking ball is fixedly connected to the outer wall of the mounting plate. A conductive plate is fixedly connected to the outer wall of the valve body. A vertical shaft is fixedly connected to the outer wall of the annular block.

[0011] Preferably, the striking assembly further includes an L-shaped block and a spring B. The L-shaped block is fixedly connected to the outer wall of the control box, the moving rod slides through the L-shaped block, and the spring B is fixedly connected between the L-shaped block and the mounting plate.

[0012] Preferably, the end of the vertical shaft furthest from the control box exceeds the distance between the toggle block and the control box, and the vertical shaft is located on the rotation trajectory of the toggle block.

[0013] Preferably, the valve body is further equipped with a pusher assembly on its interior and exterior walls. The pusher assembly includes a lifting plate B, which is fixedly sleeved on the exterior wall of the lifting rod. The exterior wall of the lifting plate B has an inclined groove. A slide rod slides through the interior of the valve body. One end of the slide rod is fixedly connected to a slide shaft. The end of the slide rod located inside the valve body is fixedly connected to a C-shaped plate. An installation shaft is rotatably connected to the inner side of the C-shaped plate. A pusher plate is fixedly sleeved on the outer wall of the installation shaft.

[0014] Preferably, one end of the sliding shaft is slidably connected inside the inclined groove, and the opening of the C-shaped plate is located inside the valve body.

[0015] The advantages of this application are:

[0016] (1) This application uses a micro motor to drive the half gear and the full gear to mesh, thereby realizing the opening and closing control of the valve plate. At the same time, the cam and the elastic element are used to drive the lifting rod to move up and down repeatedly. Then, through the cooperation of the circular block and the spiral groove, the linear motion is converted into the rotational motion of the rotating rod, which drives the scraper to closely adhere to the inner wall of the valve body for bidirectional rotation and scraping. This not only realizes the automatic control of the valve, but also forms a self-cleaning mechanism that is synchronized with the opening and closing of the valve. It effectively removes the putty powder residue adhering to the inner wall of the valve body, avoids the valve jamming or sealing failure caused by powder accumulation, significantly improves the self-cleaning effect and service life of the valve, and the entire cleaning process does not require an additional power source. It has a compact structure and low energy consumption.

[0017] (2) This application adds a tapping component. When the valve stem rotates, the actuating block periodically pushes the vertical shaft, which drives the rubber tapping ball to intermittently tap the conductive plate on the valve body through the linkage mechanism. The resulting vibration wave is transmitted to the entire valve body, causing the putty powder particles attached to the inner wall of the valve body and the surface of the valve plate to detach, effectively preventing the powder from caking and clogging. This tapping action is synchronized with the valve opening and closing process, forming an intermittent vibration unblocking mechanism. The tapping force and frequency are automatically adjusted with the valve stem rotation speed, requiring no additional power, further enhancing the unblocking and anti-sticking effect and improving the stability of equipment operation.

[0018] (3) This application sets up a pusher assembly and adds a lifting plate with an inclined groove to the lifting rod, converting its vertical reciprocating motion into the horizontal reciprocating sliding motion of the slide rod, which drives the pusher plate to push unidirectionally in the valve body flow channel. The unidirectional rotation design of the pusher plate ensures that the putty powder can be effectively promoted to pass smoothly through the valve discharge port during pushing, avoiding the obstruction of material discharge caused by local accumulation, and will not push the powder back in reverse during resetting, thus preventing pipeline blockage and material waste caused by backflow.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0030] Example 1, as Figures 1-7 As shown, a pipe valve for discharging putty powder in putty powder production includes a valve body 1, a control box 2 fixedly connected to the outer wall of the valve body 1, a valve stem 31 rotatably connected to the inner wall of the valve body 1, a valve plate 32 fixedly sleeved on the outer wall of the valve stem 31, and one end of the valve stem 31 passing through the valve body 1 and the control box 2. A full gear 33 is fixedly sleeved on the outer wall of the valve stem 31. A micro motor 34 is fixedly connected to the outer wall of the control box 2. A half gear 35 and a cam 315 are fixedly sleeved on the output shaft of the micro motor 34. A lifting rod 36 slides through the upper end of the control box 2. A lifting plate A37 is fixedly connected to the bottom of the lifting rod 36. A lifting cylinder 38 is fixedly connected to the upper end of the lifting rod 36. A rotating rod 39 is rotatably connected to the upper side of the valve body 1. A scraper 310 is fixedly connected to the lower outer wall of the rotating rod 39. A spiral groove 311 is opened on the upper outer wall of the rotating rod 39. A round block 312 is fixedly connected to the inner wall of the lifting cylinder 38. An elastic element for resetting the lifting rod 36 is assembled at the upper end of the control box 2.

[0031] The elastic element includes a connecting block 313 and a spring A314. The connecting block 313 is fixedly sleeved on the outer wall of the lifting rod 36, and the spring A314 is fixedly connected to the bottom of the connecting block 313. The elastic element enables the lifting rod 36 to automatically reset after losing the lifting action of the cam 315, ensuring the periodic reciprocating rotation of the scraper 310, thereby achieving continuous cleaning of residual putty powder on the inner wall of the valve body 1.

[0032] The bottom of the lifting plate A37 is in contact with the surface of the cam 315, and one side of the scraper 310 is in contact with the inner wall of the valve body 1. Thus, the scraper 310 can be driven by the micro motor 34 to rotate and scrape the inner wall of the valve body 1, effectively avoiding the adhesion and accumulation of putty powder on the inner wall of the valve body 1.

[0033] The lifting cylinder 38 is slidably connected to the outer wall of the rotating rod 39, and the round block 312 is slidably connected to the inside of the spiral groove 311. Thus, when the lifting rod 36 moves up and down reciprocally under the action of the cam 315, the round block 312 slides in the spiral groove 311, converting the lifting motion into the rotational motion of the rotating rod 39. This causes the scraper 310 to form a compound motion trajectory of up and down reciprocating rotation inside the valve body 1, which significantly improves the cleaning effect on all corners of the inner wall of the valve body 1.

[0034] When the above equipment is used, the valve body 1 is first installed at the outlet of the discharge pipe for putty powder production to ensure a sealed connection between the valve body 1 and the pipe. When it is necessary to open the valve to discharge putty powder, the micro motor 34 is started. The output shaft of the micro motor 34 drives the half gear 35 and the cam 315 to rotate synchronously. The half gear 35 meshes with the full gear 33 to drive the valve stem 31 and the valve plate 32 to rotate, thereby realizing the opening action of the valve. Simultaneously, the rotation of cam 315 pushes the lifting plate A37 and lifting rod 36 upward, compressing and storing energy in spring A314. During the upward movement of lifting rod 36, lifting cylinder 38 rises synchronously. Since the circular block 312 is embedded in the spiral groove 311 on the outer wall of rotating rod 39, the linear motion of lifting cylinder 38 is converted into the rotational motion of rotating rod 39 through the cooperation of circular block 312 and spiral groove 311. Rotating rod 39 drives scraper 310 to perform circumferential scraping along the inner wall of valve body 1, effectively removing putty powder residue adhering to the inner wall of valve body 1, thus preventing valve jamming or sealing failure caused by powder accumulation. When the half gear 35 rotates to the toothless section and disengages from the full gear 33, the valve plate 32 remains open. The protrusion of the cam 315 gradually moves away from the lifting plate A37. The spring A314 releases its elastic potential energy to push the lifting rod 36 to reset and move downward. The lifting cylinder 38 then descends. The circular block 312 slides in the opposite direction along the spiral groove 311, driving the rotating rod 39 and the scraper 310 to rotate and scrape in the opposite direction, forming a bidirectional cleaning effect on the inner wall of the valve body 1. This reciprocating motion mode ensures that all areas of the inner wall of the valve body 1 can be thoroughly cleaned, significantly improving the self-cleaning effect and service life of the valve.

[0035] Example 2, as Figure 5 As shown, the outer wall of the control box 2 is equipped with a striking assembly, which includes a toggle block 41. The toggle block 41 is fixedly connected to one end of the valve stem 31 located on the outside of the control box 2. The outer wall of the control box 2 is rotatably connected to an annular block 42. The outer wall of the annular block 42 is hinged to a connecting rod A43. The other end of the connecting rod A43 is hinged to a moving rod 44. The end of the moving rod 44 away from the connecting rod A43 is fixedly connected to a mounting plate 45. The outer wall of the mounting plate 45 is fixedly connected to a rubber striking ball 46. The outer wall of the valve body 1 is fixedly connected to a conductive plate 47. The outer wall of the annular block 42 is fixedly connected to a vertical shaft 48.

[0036] The striking assembly also includes an L-shaped block 49 and a spring B410. The L-shaped block 49 is fixedly connected to the outer wall of the control box 2. The moving rod 44 slides through the L-shaped block 49. The spring B410 is fixedly connected between the L-shaped block 49 and the mounting plate 45. The L-shaped block 49 and the spring B410 can ensure the stability of the moving rod 44 during reciprocating motion, while providing continuous elastic restoring force for the rubber striking ball 46, ensuring the continuity and effectiveness of the striking action.

[0037] The end of the vertical shaft 48 that is away from the control box 2 exceeds the distance between the toggle block 41 and the control box 2, and the vertical shaft 48 is located on the rotation trajectory of the toggle block 41. When the valve stem 31 drives the toggle block 41 to rotate, the toggle block 41 will periodically strike the vertical shaft 48, thereby driving the annular block 42 to swing back and forth.

[0038] When the above-mentioned device is used, when the valve stem 31 reciprocates under the drive of the micro motor 34 to control the opening and closing of the valve plate 32, the actuating block 41 rotates synchronously with the valve stem 31. The rotation trajectory of the actuating block 41 forms an interference fit with the vertical shaft 48. When the actuating block 41 rotates to the position of contacting the vertical shaft 48, the actuating block 41 pushes the vertical shaft 48 to rotate the annular block 42. The rotational motion of the annular block 42 is transmitted to the moving rod 44 through the connecting rod A43, driving the moving rod 44 to slide outward along the guide hole of the L-shaped block 49. The spring B410 is stretched and stored, and the mounting plate 45 and the rubber striking ball 46 move away from the conducting plate 47. As the valve stem 31 continues to rotate, when the vertical shaft 48 rotates to the furthest point away from the moving rod 44, the vertical shaft 48 rotates. Since there is no obstruction from the actuating block 41 on its other side, the annular block 42 rotates and resets under the rebound force of the spring B410. The moving rod 44 drives the rubber striking ball 46 to move quickly toward the transmission plate 47 and generate a striking action. The vibration wave generated by the striking is transmitted to the entire valve body 1 through the transmission plate 47, causing the putty powder particles attached to the inner wall of the valve body 1 and the surface of the valve plate 32 to detach, effectively preventing the powder from caking and clogging. Since the actuating block 41 rotates periodically with the valve stem 31, the above-mentioned striking action is synchronized with the valve opening and closing process, forming an intermittent vibration clearing mechanism. Moreover, the striking force and frequency are automatically adjusted with the rotation speed of the valve stem 31, requiring no additional power source, and the structure is compact and energy-efficient.

[0039] Example 3, as Figures 6-8 As shown, the valve body 1 is also equipped with a pusher assembly inside and on its outer wall. The pusher assembly includes a lifting plate B51, which is fixedly sleeved on the outer wall of the lifting rod 36. The outer wall of the lifting plate B51 is provided with an inclined groove 52. A slide rod 53 slides through the inside of the valve body 1. One end of the slide rod 53 is fixedly connected to a slide shaft 54. The end of the slide rod 53 located inside the valve body 1 is fixedly connected to a U-shaped plate 55. The inner side of the U-shaped plate 55 is rotatably connected to an installation shaft 56. A pusher plate 57 is fixedly sleeved on the outer wall of the installation shaft 56.

[0040] A section of the sliding shaft 54 ​​is slidably connected inside the inclined groove 52. The opening of the shaped plate 55 is located inside the valve body 1. The inclined trajectory of the inclined groove 52 drives the sliding shaft 54 ​​and the sliding rod 53 to reciprocate horizontally inside the valve body 1.

[0041] In practical use, the lifting rod 36 reciprocates under the alternating action of the cam 315 and the spring A314: when the cam 315 rotates to the lifting stage, it pushes the lifting rod 36 upward, while the spring A314 is compressed and stores energy; when the cam 315 enters the return stage, the spring A314 releases energy, pushing the lifting rod 36 downward, thus achieving a continuous and stable lifting cycle. The lifting plate B51 moves up and down synchronously with the lifting rod 36 through a rigid connection, and its movement trajectory is strictly controlled by the lifting rod 36. Since the sliding shaft 54 ​​is embedded in the inclined groove 52 on the outer wall of the lifting plate B51 and maintains sliding contact within the groove, the vertical movement of the lifting plate B51 is guided by the inclined structure of the inclined groove 52 to generate lateral displacement of the sliding shaft 54. This mechanism converts the vertical movement of the lifting plate B51 into the reciprocating sliding of the slide rod 53 in the horizontal direction, realizing the conversion and transmission of the direction of movement; When the lifting rod 36 rises, the inclined section of the sloping groove 52 pushes the sliding shaft 54 ​​and the sliding rod 53 to move towards the inside of the valve body 1. The shaped plate 55 drives the pusher plate 57 to extend into the flow channel area of ​​the valve body 1. The pusher plate 57 mechanically pushes the putty powder during its forward movement, promoting the smooth passage of the powder through the valve discharge port and avoiding the obstruction of material discharge caused by local accumulation. When the lifting rod 36 falls back to its original position, the sloping groove 52 pulls the sliding shaft 54 ​​in the opposite direction, causing the sliding rod 53 to move outward, so that the pusher plate 57 is reset. When the pusher plate 57 is fixedly sleeved on the outer wall of the mounting shaft 56, and the mounting shaft 56 is rotatably connected to the inner side of the U-shaped plate 55, the pusher plate 57 will rotate inward, thus preventing the putty powder from being pushed back. At the same time, when pushing the putty powder inward, due to the restriction of the U-shaped plate 55, the pusher plate 57 will not rotate outward, thus achieving an effective one-way pushing function, ensuring that the powder always flows in the discharge direction, and preventing backflow from causing pipe blockage and material waste.
