Description

Technical Field

[0001] This invention relates to the field of molding plate polishing technology, and in particular to a groove polishing device for ECP hollow extrusion molding plates. Background Technology

[0002] In the production and processing of ECP hollow extrusion molding sheets, the groove structure is a key part for its assembly and connection, requiring extremely high surface smoothness and dimensional accuracy. Traditional groove grinding mostly relies on manual operation or simple equipment. Manual grinding is inefficient, labor-intensive, and it is difficult to ensure that the groove depth is consistent and the surface is flat. Simple equipment lacks precise positioning and spacing adjustment mechanisms, cannot adapt to molding sheets with different groove spacings, and is prone to problems such as grinding misalignment and missed grinding, which seriously affects the subsequent assembly quality and service stability of the molding sheet.

[0003] With the increasing demand for ECP hollow extruded sheets from the construction and building materials industries, the market's requirements for processing efficiency and precision are constantly rising. Existing grinding equipment suffers from poor adaptability and insufficient grinding synchronization. When the groove spacing of the formed sheet changes, the equipment needs to be readjusted or parts replaced, leading to production interruptions and increased costs. At the same time, some equipment lacks an effective sheet feeding and positioning mechanism, making the sheet prone to displacement during grinding, further reducing grinding precision and making it difficult to meet the needs of large-scale, high-quality production. Summary of the Invention

The several elliptical slide plates are linked together through a linkage mechanism. Each of the elliptical slide plates has an L-shaped connecting plate fixed at its left end, and a U-shaped plate fixed at its bottom end. A driven shaft is rotatably inserted through the center of the bottom surface of each U-shaped plate. The U-shaped plate is connected to the driven shaft via a meshing mechanism.

[0007] Preferably, each of the fixed shafts is fixedly provided with a driven link in the lower middle part, and the outer ends of several driven links located on the same side are respectively movably hinged to the same hinge rod.

[0008] Preferably, a pair of symmetrically distributed electric telescopic cylinders are hinged at the two corners on the left side of the top surface of the U-shaped horizontal plate. Each electric telescopic cylinder has a fixed swing arm hinged at the end of its telescopic rod. The outer end of each fixed swing arm is fixedly connected to the driven connecting rod on the corresponding side in an "L" shape.

[0009] Preferably, the linkage mechanism includes a hinged short rod and a hinged long rod. A fixed pin is fixedly provided on the right side of the top surface of each elliptical slide block. The top ends of a pair of fixed pins located on the front and rear sides are provided with hinged short rods that are movably hinged in a "V" shape. The top ends of the remaining fixed pins are provided with hinged long rods that are movably hinged in an "X" shape. The outer ends of adjacent hinged short rods and hinged long rods are hinged to each other.

[0010] Preferably, each of the elliptical slide plates has fixed sliding holes at both ends, each of the fixed sliding rods is slidably inserted into several fixed sliding holes on the same side, each of the elliptical slide plates has a fixed through hole in the middle, and a threaded cylinder is fixedly inserted into a pair of circular through holes on the front and rear sides.

[0011] Preferably, a fixed long shaft is rotatably inserted between the pair of side plates, and a pair of symmetrically distributed threaded screws are fixed on the front and rear sides of the fixed long shaft. Each threaded screw is helically inserted into the corresponding threaded cylinder and threadedly connected to it. A second motor with the output end facing backward is fixedly installed on the front side of the front side plate, and the motor shaft end of the second motor is fixedly connected to the front end of the fixed long shaft.

[0012] Preferably, the meshing mechanism includes a driving bevel gear and a driven bevel gear. Hollow shafts are rotatably inserted into each U-shaped plate and are distributed throughout.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the first motor drives the roller shaft and roller to rotate synchronously, so as to realize the smooth conveying of the forming plate to the right; the electric telescopic cylinder drives the rubber cylinder to rotate and press against both sides of the forming plate through the linkage of components such as the fixed swing arm, driven connecting rod and fixed shaft, so as to avoid damage to the plate and ensure that the forming plate is centered and aligned, providing a precise and stable reference for groove grinding and improving the accuracy of grinding position; 2. In this invention, the fixed long shaft and the threaded screw are driven to rotate by the second motor. In conjunction with the threaded cylinder and the fixed slide rod, the elliptical slide plate is driven to slide. Then, through the linkage of the hinged short rod and the hinged long rod, the grinding head is equidistantly distributed and precisely controlled. It can flexibly adapt to the forming plate with different groove spacing without replacing the equipment or making major adjustments, thus broadening the scope of application of the equipment. 3. In this invention, the third motor drives the active long shaft to rotate, and through the cooperation of the limiting clip and the limiting slot, it drives the hollow shaft and the active bevel gear to move synchronously. Then, through the meshing transmission of the active bevel gear and the driven bevel gear, all grinding heads can rotate synchronously. Even if the spacing between the grinding heads is adjusted, the grinding effect can still be maintained, which greatly improves the consistency and processing efficiency of groove grinding. In summary, this invention, through the coordinated operation of three major modules—conveying and positioning, spacing adjustment, and synchronous grinding—ensures both the stability and positioning accuracy of the forming plate conveying and achieves flexible adaptation of the grinding head spacing and synchronous and efficient grinding. It effectively solves the problems of poor adaptability, low grinding accuracy, and insufficient efficiency of traditional equipment, and meets the batch high-quality processing requirements of ECP hollow extrusion forming plate grooves.

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Example 1: This example provides a groove grinding device for ECP hollow extrusion molded plates. See [link / reference]. Figures 1 to 6 Specifically, it includes a frame bracket 100, on the top surface of which a U-shaped horizontal plate 101 is fixed. The frame bracket 100 and the U-shaped horizontal plate 101 provide a stable mounting base for each component. Rollers 102 are rotatably installed inside the U-shaped horizontal plate 101, and a roller 103 is fixedly sleeved in the middle of each roller 102. The rollers 102 and rollers 103 rotate synchronously to transmit the driving force of the first motor 104. A forming plate 105 is carried on several rollers 103, and the forming plate 105 is conveyed to the right by rotation. Several equidistant fixed shafts 200 are rotatably inserted on the front and rear sides of the top of the U-shaped horizontal plate 101. The fixed shafts 200 serve as the rotational support shafts of the fixed connecting rods 201, transmitting swinging power. Each fixed shaft 200 has a fixed connecting rod 201 fixed at its top end, and a connecting shaft 202 is rotatably inserted at the outer end of each fixed connecting rod 201. The fixed connecting rods 201 connect the fixed shafts 200 and the connecting shafts 202, driving the rubber cylinders 203 to swing and adjust their positions. Each connecting shaft 202 has a rubber cylinder 203 fixedly sleeved at its bottom end. The connecting shafts 202 enable the rotation of the rubber cylinders 203, adapting to the conveying movement of the forming plate 105. Each rubber cylinder 203 slides against the forming plate 105, avoiding damage to the plate and achieving center alignment. A pair of symmetrically distributed side plates 300 are fixedly provided on the right side of the top surface of the U-shaped horizontal plate 101. The side plates 300 provide mounting support for components such as fixed slide rods 301, fixed long shafts 308, and active long shafts 408. A pair of parallel fixed slide rods 301 are fixed between the pair of side plates 301. The fixed slide rods 301 limit the sliding trajectory of the elliptical slide plate 302 to ensure its smooth movement. Several equidistant elliptical slide plates 302 are slidably sleeved between the pair of fixed slide rods 301. The elliptical slide plates 302 adjust the spacing of the grinding heads 406 by sliding. Several elliptical slide plates 302 are linked together through a linkage mechanism. Each elliptical slide plate 302 has an L-shaped connecting plate 400 fixedly installed at its left end. The L-shaped connecting plate 400 connects the elliptical slide plate 302 to the U-shaped plate 401 and transmits the position adjustment action. Each L-shaped connecting plate 400 has a U-shaped plate 401 fixedly installed at its bottom end. The U-shaped plate 401 provides mounting support for components such as the hollow shaft 402 and the driven shaft 404. Each U-shaped plate 401 has a driven shaft 404 rotatably inserted through the center of its bottom surface. The driven shaft 404 transmits power to the driven bevel gear 405 and drives the grinding head 406 to rotate. The U-shaped plate 401 is connected to the driven shaft 404 through a meshing mechanism. Each driven shaft 404 has a grinding head 406 fixedly sleeved at its bottom end for grinding the forming plate 105. The grinding head 406 directly contacts the groove of the forming plate 105 and performs the grinding operation by rotation.

[0019] It should be noted that: such as Figure 3 and Figure 4 As shown, a number of first motors 104 are fixedly installed on the back of the U-shaped horizontal plate 101 at equal intervals. The motor shaft end of each first motor 104 is fixedly connected to the rear end of the corresponding roller 102. The first motor 104 provides conveying power and drives the corresponding roller 102 and roller 103 to rotate synchronously. Each fixed shaft 200 has a driven link 207 fixed in the middle and lower part. The outer ends of several driven links 207 located on the same side are respectively hinged to the same hinge rod 204. The hinge rod 204 links all driven links 207 on the same side to ensure that multiple positioning components move synchronously. A pair of symmetrically distributed electric telescopic cylinders 205 are hinged at the two corners on the left side of the top surface of the U-shaped horizontal plate 101. Each electric telescopic cylinder 205 has a fixed swing arm 206 hinged at the end of its telescopic rod. The outer end of each fixed swing arm 206 is fixedly connected to the driven link 207 on the corresponding side in an "L" shape. The fixed swing arm 206 transmits the power of the electric telescopic cylinder 205 and drives the driven link 207 to swing.

[0020] The working principle of this embodiment is as follows: After the first motors 104 are started, their motor shafts directly drive the corresponding roller shafts 102 and rollers 103 to rotate synchronously. Through the coordinated action of the rollers 103, the forming plate 105 is smoothly conveyed to the right. A pair of electric telescopic cylinders 205 drive the telescopic rod to extend, which in turn drives the driven connecting rod 207, fixed shaft 200 and fixed connecting rod 201 on the corresponding side to swing through the fixed swing arm 206. With the help of the linkage hinge relationship between the hinge rod 204 and all the driven connecting rods 207, the remaining driven connecting rods 207, fixed shaft 200 and fixed connecting rod 201 swing synchronously. Since the connecting shaft 202 is rotatable, several rubber cylinders 203 rotate and press against the front and rear sides of the forming plate 105 respectively, so that the forming plate 105 automatically centers and aligns, and maintains a stable rightward conveying state. A linkage mechanism drives several elliptical slide plates 302 to maintain precise equidistant distribution, ensuring that the grinding heads 406 on them are aligned with the grooves on the top surface of the forming plate 105. Then, the meshing mechanism drives all the grinding heads 406 to rotate synchronously, and the grinding work of the grooves on the top surface of the forming plate 105 is completed by the coordinated grinding of several grinding heads 406.

[0021] Example 2: Based on Example 1, this example solves the problem of difficulty in flexibly adjusting the spacing of the grinding heads 406 according to the groove spacing of the forming plate 105 by adding a specific linkage mechanism, thus achieving precise control of the equidistant distribution of the grinding heads 406. It also includes: In the specific implementation process, such as Figure 5 and Figure 6As shown, the linkage mechanism includes a hinged short rod 305 and a hinged long rod 306. A fixed pin 304 is fixedly provided on the right side of the top surface of each elliptical slide plate 302. The top ends of a pair of fixed pins 304 located on the front and rear sides are provided with hinged short rods 305 that are movably hinged in a "V" shape. The top ends of the remaining fixed pins 304 are provided with hinged long rods 306 that are movably hinged in an "X" shape. The outer ends of adjacent hinged short rods 305 and hinged long rods 306 are hinged to each other. The hinged short rods 305 cooperate with the hinged long rods 306 to realize the equidistant linkage of the elliptical slide plate 302. Each elliptical slide plate 302 has fixed sliding holes at both ends. Each fixed sliding rod 301 is slidably inserted into several fixed sliding holes on the same side. Each elliptical slide plate 302 has a fixed through hole in the middle. A threaded cylinder 303 is fixedly inserted into a pair of circular through holes on the front and rear sides. The threaded cylinder 303 is threadedly engaged with the threaded screw 309 to convert the rotational motion into the linear motion of the elliptical slide plate 302. A fixed long shaft 308 is rotatably inserted between a pair of side plates 300. The fixed long shaft 308 transmits power to the second motor 307, driving the threaded screws 309 on both sides to rotate synchronously. A pair of symmetrically distributed threaded screws 309 are fixed on the front and rear sides of the fixed long shaft 308. Each threaded screw 309 is helically inserted into the corresponding threaded cylinder 303 and threadedly connected to it. A second motor 307 with the output end facing backward is fixedly installed on the front side of the side plate 300. The motor shaft end of the second motor 307 is fixedly connected to the front end of the fixed long shaft 308. The second motor 307 provides the power for pitch adjustment and drives the fixed long shaft 308 and the threaded screws 309 to rotate.

[0022] The working principle of this embodiment is as follows: After the second motor 307 starts, it drives the fixed long shaft 308 and a pair of threaded screws 309 to rotate synchronously. By utilizing the threaded engagement between the threaded screws 309 and the threaded cylinder 303, the elliptical slide plates 302 on the front and rear sides slide relative to or in opposite directions along the fixed slide rod 301. Through the linkage between the hinged short rod 305 and the hinged long rod 306, all the elliptical slide plates 302 are automatically distributed at equal intervals along the fixed slide rod 301, which synchronously drives several U-shaped plates 401 and the grinding head 406 to maintain an equidistant state.

[0023] Example 3: Based on Example 2, this example solves the problem of the grinding head 406 being difficult to rotate synchronously and stably after the spacing is adjusted by adding a specific meshing mechanism. This allows the grinding head 406 to maintain synchronous and efficient grinding even when its position changes. It also includes: In the specific implementation process, such as Figure 5 and Figure 6As shown, the meshing mechanism includes a driving bevel gear 403 and a driven bevel gear 405. Hollow shafts 402 are rotatably inserted into each U-shaped plate 401 and are distributed through the plate. The hollow shafts 402 carry the driving bevel gears 403. Each hollow shaft 402 is fixedly fitted with a driving bevel gear 403. The top end of each driven shaft 404 is fixedly fitted with a driven bevel gear 405. Adjacent driving bevel gears 403 and driven bevel gears 405 mesh with each other, changing the direction of power transmission and driving the driven shaft 404 to rotate. An active long shaft 408 is rotatably inserted between a pair of side plates 300. The active long shaft 408 passes through all hollow shafts 402, transmits the power of the third motor 407, and drives multiple sets of active bevel gears 403 to rotate synchronously. The active long shaft 408 is inserted through several hollow shafts 402 in sequence. The third motor 407 with the output end facing backward is fixedly installed on the front of the side plate 300. The end of the motor shaft of the third motor 407 is fixedly connected to the front end of the active long shaft 408. The third motor 407 provides grinding driving force and drives the active long shaft 408 to rotate. Each hollow shaft 402 has a pair of limiting slots, and the active long shaft 408 has a pair of limiting strips fixed on it. The outer edge of each limiting strip slides into the corresponding limiting slots, so as to realize the synchronous rotation of the active long shaft 408 and the hollow shaft 402, while allowing the hollow shaft 402 to slide along the active long shaft 408.

[0024] The working principle of this embodiment is as follows: After the third motor 407 is started, its motor shaft drives the active long shaft 408 to rotate synchronously. With the help of the limiting cooperation of the limiting strip and the limiting slot, the hollow shaft 402 and the active bevel gear 403 are driven to rotate synchronously. The active bevel gear 403 meshes with the driven bevel gear 405, which in turn drives the driven shaft 404 and the grinding head 406 to rotate synchronously, thus completing the grinding operation.

[0025] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
