Description

Technical Field

[0001] This utility model belongs to the field of valve plate grinding technology, specifically, it relates to an automatic grinding and deburring equipment for duct check valve plates. Background Technology

[0002] Duct check valves are key components in ventilation systems that prevent airflow from flowing backwards. They are widely used in building ventilation, industrial dust removal, and air conditioning systems. Their valve plates are usually made of metal or polymer materials and come in various shapes with complex edge contours.

[0003] Chinese Patent No. CN214923095U discloses a valve plate grinding machine. Compared with the prior art, the advantages and positive effects of this utility model are as follows: (1) The valve plate grinding machine of this utility model uses a valve plate fixing device to fix the valve plate to be ground. During the grinding process, the operator does not need to hold it, which reduces the workload of the operator and reduces safety accidents; (2) The encoder of the electric cylinder can accurately control the feed displacement and feed rate of the electric cylinder screw. The electric cylinder drives the grinding wheel to feed at the set rate. When the set feed displacement is reached, the grinding wheel no longer moves towards the valve plate, thereby avoiding the defective products generated by grinding and preventing the grinding wheel from being overloaded; however, this grinding device can only adjust the fixed distance between the valve plate and the grinding wheel. The angle is fixed during grinding, and the edge is easy to turn over after grinding, which produces burrs and makes the overall grinding effect poor.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an automatic grinding and deburring device for duct check valve plates, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] An automatic grinding and deburring device for duct check valve plates includes: a base, characterized in that a distance adjusting screw is installed through the base, a first crank is provided at one end of the distance adjusting screw, a vertical base is provided at the top of the base, a height adjusting screw is vertically installed inside the vertical base, a second crank is provided at the top of the height adjusting screw, an extension frame is sleeved on the surface of the height adjusting screw, a valve plate fixing frame is provided at the top of the extension frame, a fixing screw is vertically installed inside the valve plate fixing frame, a fixing screw sleeve is sleeved on the surface of the fixing screw, a bottom ring is provided at the front end of the extension frame, a pressure rod is provided at the top of the bottom ring, a valve plate is arranged between the pressure rods, a grinding seat is provided at the top of the bottom end of the base, a motor is provided at the top of the grinding seat, a locking head is provided below the motor, and a grinding head is provided below the locking head.

[0008] Optionally, a ring is fixedly connected to the bottom of the fixing screw, and a ring sleeve is fitted around the outer ring of the ring.

[0009] Optionally, the pressure bar consists of four small bars.

[0010] Optionally, the valve plate rotates in the same direction as the fixed screw sleeve.

[0011] Optionally, the grinding head can be replaced.

[0012] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0013] 1. This automatic deburring equipment for duct check valve plates uses two screws to adjust the position of the valve plate, allowing it to contact the grinding head in both vertical and horizontal directions. This enables better deburring of the edges at the grinding location. By changing the shape of the grinding head, the angle of the grinding edge can be altered, resulting in a smoother transition at the grinding location edge.

[0014] 2. The automatic grinding and deburring equipment for the duct check valve plate uses a fixed screw sleeve to rotate and push the upper pressure rod downward to cooperate with the lower pressure rod to clamp and fix the valve plate. The valve plate is ground by rotating and contacting the grinding head. The valve plate will not shake during the grinding process, making it more stable and resulting in a better and more aesthetically pleasing grinding effect.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] Please see Figure 1-4 As shown in the figure, this embodiment provides an automatic grinding and deburring device for duct check valve plates, including: a base 1.

[0026] like Figure 1-4As shown, in this embodiment, a distance adjusting screw 101 is installed through the base 1. A first crank 102 is provided at one end of the distance adjusting screw 101. A vertical base 2 is provided on the top of the base 1. A height adjusting screw 201 is vertically installed inside the vertical base 2. A second crank 202 is provided on the top of the height adjusting screw 201. An extension bracket 3 is sleeved on the surface of the height adjusting screw 201. A valve plate fixing bracket 4 is provided on the top of the extension bracket 3. A fixing screw 401 is vertically installed inside the valve plate fixing bracket 4. A fixing screw 401 is fitted with a fixing screw sleeve 402. A bottom ring 406 is provided at the front end of the extension frame 3, and a pressure rod 405 is provided at the top of the bottom ring 406. A valve plate 6 is provided between the pressure rods 405. A grinding seat 5 is provided at the top of the end of the base 1, and a motor 501 is provided at the top of the grinding seat 5. A locking head 503 is provided below the motor 501, and a grinding head 504 is provided below the locking head 503. The bottom part of the vertical base 2 is embedded in the base 1, and the distance adjustment screw 101 passes through the vertical base 1. At the threaded hole of the vertical base 2, rotating the first crank 102 moves the vertical base 2 within the base 1, bringing the installed valve plate 6 closer to the grinding head 504. Similarly, the height adjustment screw 201 inside the vertical base 2 passes through the threaded hole on the extension frame 3, and the end of the extension frame 3 is embedded in the vertical base 2. By rotating the second crank 102, the threaded engagement achieves height adjustment of the extension frame 3 within the vertical base 2. The two screws rotate in coordination, enabling the extension frame 3 to move in both the horizontal and vertical directions. The valve plate 6 is fixed by two pressure rods 405 clamping it from top to bottom on the extension frame 3. The upper pressure rod 405 passes through the fixing screw 402 and the valve plate fixing frame 4 through the top fixing screw 401, and fixes the fixing screw 402 in the valve plate fixing frame 4 to prevent it from falling off. By rotating the fixing screw 402, the internal thread and the fixing screw 401 are engaged, realizing the up and down movement of the fixing screw 401, thereby driving the bottom pressure rod 405 to move up and down to clamp or release the valve plate 6.

[0027] like Figure 1-4 As shown, in this embodiment, a ring 403 is fixedly connected to the bottom of the fixing screw 401, and a ring sleeve 404 is sleeved on the outer ring of the ring 403. The ring sleeve 404 is directly connected to the pressure rod 405. The top opening is small and the inner opening is large, so that the ring 403 is completely wrapped and a gap is left, so that the fixing screw 401 connected to the ring 403 can rotate independently relative to the ring sleeve 404 connected to the pressure rod 405. The same applies to the bottom pressure rod 405 and the bottom ring 406. The bottom ring 406 can also rotate independently, so that the valve plate 6 can also rotate after being fixed, so that the overall edge area can be polished.

[0028] like Figure 1-4As shown, the pressure rod 405 in this embodiment consists of four small rods; the conventional valve plate 6 is located inside the valve body and requires a rotating shaft to flip it to open and close the valve body. The rotating shaft of the circular valve plate 6 is usually located in the middle position, and the area through which it passes is usually provided with a protrusion on the outside. At this time, the small rods clamp the valve plate 6 by fitting against the edge of the protrusion, so that the valve plate 6 will not loosen during manual rotation.

[0029] like Figure 1-4 As shown, in this embodiment, the rotation direction of the valve plate 6 is the same as that of the fixing sleeve 402. During the grinding and rotation of the valve plate 6, one hand needs to hold the fixing sleeve 402 to prevent it from rotating, while the other hand is used to rotate the valve plate 6. When rotating, the friction of the pressure rod 405 is relatively large, which has a certain probability of driving the fixing screw 401 to rotate. With conventional straight thread, the fixing sleeve 402 is rotated clockwise to tighten the pressure rod 405. When the valve plate 6 also rotates clockwise, the top pressure rod 405 is subjected to downward pressure from the thread under the fixed state of the fixing sleeve 402, so that the force of fixing and clamping the valve plate 6 will not decrease, and the overall fixation will only become tighter and tighter until it is maintained at the maximum value.

[0030] like Figure 1 , 2 As shown, the grinding head 504 in this embodiment can be replaced; wherein, the grinding head 504 is clamped by the locking head 503, which rotates to hold the mounting rod at the end of the grinding head 504. By installing grinding heads 504 of different shapes, the contact area of ​​the grinding position can be changed, thereby achieving different grinding effects.

[0031] Working principle: First, place the valve plate 6 to be ground on the bottom ring 406. Rotate the fixing sleeve 402 to move it downward, driving the fixing screw 401 and the upper pressure rod 405 to press down. Together with the lower pressure rod 405, the valve plate 6 is clamped and fixed. Then, by rotating the first crank 102, the distance adjusting screw 101 is rotated, pushing the vertical base 2 and the valve plate 6 closer to or further away from the grinding head 504 in the horizontal direction. Next, rotate the second crank 202 to rotate the height adjusting screw 201, adjusting the height of the extension frame 3 and the valve plate 6 in the vertical direction, thereby flexibly adjusting the relative position of the valve plate 6 and the grinding head 504 to achieve multi-angle grinding. Start the motor 501, which drives the grinding head 504 to rotate at high speed. The operator fixes the rotating sleeve 402 and manually rotates the valve plate 6 so that its edge contacts the grinding head 504 for uniform deburring. Because the contact area between the pressure rod 405 and the valve plate 6 is small, the central protrusion structure of the valve plate can be avoided, ensuring stable clamping.
