Description

Technical Field

[0001] This utility model relates to the technical field of grinding machines, and in particular to a template surface grinding machine. Background Technology

[0002] During the production process, the outer surface of the template needs to be ground to achieve a set flatness. Chinese utility model patent CN217776444U discloses a grinding device for decorative insulation templates. This device includes a base, a processing table fixedly mounted on the top of the base, a through groove in the center of the top of the processing table, and a grinding roller driven by a motor rotatably mounted within the through groove. The base has a collection chamber communicating with the through groove for collecting waste debris. A collection frame is located at the bottom of the collection chamber. An exhaust fan is located on one side of the base, and the air inlet of the exhaust fan is connected to the collection chamber via a connecting pipe. A filter device is installed inside the collection chamber to trap waste debris. Two rectangular fixed frames are fixedly connected to the top of the base, and movable plates are movably connected between the inner walls of the fixed frames. Two pressure rollers rotating in the same direction are rotatably connected between the movable plates. This allows the waste debris generated during the grinding process to be collected by the exhaust fan in conjunction with the collection chamber, preventing the waste debris from scattering and polluting the environment.

[0003] However, the aforementioned grinding machine does not have a limiting mechanism for the pressure roller. Instead, it controls the gap between the pressure roller and the processing table solely through the extension and retraction of the cylinder. This results in an unstable gap, and when the gap is too large or too small, the pressure of the pressure roller on the template will be different, leading to an unstable grinding effect. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a template surface grinding machine that can limit the size of the gap between the two pressure rollers and the platform, so as to stabilize the gap and make the surface grinding effect of the template more stable.

[0005] This utility model discloses a template surface grinding machine, which further includes a platform, grinding rollers, and a chip box. A through groove runs vertically through the center of the platform, and the grinding rollers are rotatably mounted in the groove. The chip box is installed at the bottom of the platform and is used to collect wood chips. It also includes an upper frame, a push cylinder, a clamping frame, two pressure rollers, multiple limiting rollers, and multiple adjusting components. The upper frame is mounted on the platform, and the fixed end of the push cylinder is mounted on the upper frame. The lower end of the piston rod of the push cylinder is connected to the clamping frame. The two pressure rollers are rotatably mounted at both ends of the clamping frame, located on the left and right sides of the grinding rollers. The multiple limiting rollers are mounted on the clamping frame via multiple adjusting components. The multiple adjusting components are used to adjust the height of the multiple limiting rollers. The multiple limiting rollers extend below the two pressure rollers and adjust the height of the pressure rollers relative to the surface. The gap between the platforms is limited; multiple adjustment components are operated according to the thickness of the template, so that multiple limiting rollers extend under the two pressure rollers respectively, and the distance of the multiple limiting rollers extending under the two pressure rollers is adjusted, which is the limiting gap; during operation, the piston rod of the push cylinder extends downward, causing the clamping frame and the two pressure rollers to descend, so that the multiple limiting rollers roll and connect with the platform, thereby limiting the gap between the two pressure rollers and the platform; the grinding roller rotates at high speed, and the two pressure rollers rotate synchronously, thereby rubbing the template to move on the platform, so that the grinding roller performs surface grinding on the template surface. Compared with the existing technology, it can limit the size of the gap between the two pressure rollers and the platform, making the gap stable, thereby stabilizing the pressure of the two pressure rollers on the template, and making the surface grinding effect of the template more stable.

[0006] Preferably, the adjustment assembly includes a sleeve, a worm gear, a handwheel, and a roller mounting rod. The sleeve is mounted on the clamping frame, the worm gear is vertically rotatably mounted in the mounting groove of the sleeve, the handwheel is mounted on the upper end of the worm gear, the upper end of the roller mounting rod is slidably inserted into the slide groove of the sleeve, the upper part of the roller mounting rod meshes with the worm gear, and the lower end of the roller mounting rod rotatably mounts a limiting roller. By rotating the worm gear with the handwheel, the worm gear meshes and drives the roller mounting rod to rise and fall along the slide groove of the sleeve, thereby adjusting the distance by which the limiting roller extends out from under the pressure roller. The operation is convenient and has a self-locking function, and the position of the limiting roller is stable and reliable after adjustment.

[0007] Preferably, the device further includes two driven wheels, a motor, a driving wheel, and two transmission belts. The two driven wheels are concentrically mounted on the central shafts of the two pressure rollers, the motor is mounted on the clamping frame, the driving wheel is mounted on the output shaft of the motor, one end of each of the two transmission belts is fitted onto the two driven wheels, and the other end of each of the two transmission belts is fitted onto the driving wheel. The motor drives the driving wheel to rotate, and the driving wheel drives the two driven wheels to rotate through the two transmission belts. The two driven wheels drive the two pressure rollers to rotate, and the two pressure rollers rotate synchronously and in the same direction, ensuring stable and reliable driving.

[0008] Preferably, it also includes two shafts, two torsion springs, two swing arms, and two auxiliary pressure rollers. The two shafts are installed opposite each other on both sides of the clamping frame. The upper ends of the two swing arms are elastically connected to the two shafts through two torsion springs, and the two auxiliary pressure rollers are rotatably installed at the lower ends of the two swing arms. The torque of the two torsion springs drives the two auxiliary pressure rollers to rotate downward through the two swing arms, so that the two auxiliary pressure rollers assist in clamping the template in the middle of the two pressure rollers, avoiding the decline in grinding effect caused by poor contact between the template and the grinding roller due to lack of clamping force, and improving grinding stability.

[0009] Preferably, it also includes two upper pull rods and a telescopic rod. The lower ends of the two upper pull rods are respectively connected to two shafts, and the two ends of the telescopic rod are respectively rotatably connected to the two upper pull rods. When the telescopic rod extends or retracts, it pushes the two upper pull rods to open or close in opposite directions, thereby driving the two shafts to rotate. Then, the distance between the two auxiliary pressure rollers extending below the two pressure rollers is adjusted by the two swing arms to achieve different auxiliary pressing effects on the template.

[0010] Preferably, it also includes two lower support rollers, which are rotatably installed in the through groove of the platform and are respectively located below the two auxiliary pressure rollers; the two lower support rollers, together with the two auxiliary pressure rollers, provide rolling support for the template located between the two pressure rollers, thereby improving the grinding stability of the template.

[0011] Preferably, the device also includes an air extractor and two breathable sponge strips. The air extractor is installed below the platform, with its suction end extending into the interior of the chip box. Two vertically connected adsorption grooves are provided on the platform, communicating with the interior of the chip box. The two adsorption grooves are located on the left and right sides of the groove, respectively, and the two breathable sponge strips are installed in the two adsorption grooves. When the air extractor operates, it draws out the air from inside the chip box, thereby creating a negative pressure inside the chip box. This causes the wood chips ground by the grinding roller to be sucked into the chip box through the groove, where they are collected. At the same time, the negative pressure inside the chip box vacuum adsorbs the lower surface of the template through the two breathable sponge strips, thus ensuring that the template is tightly attached to the platform and improving the stability of the template.

[0012] Compared with the prior art, the beneficial effects of this utility model are: it can limit the size of the gap between the two pressure rollers and the platform, so as to stabilize the gap, thereby stabilizing the pressure of the two pressure rollers on the template and making the surface grinding effect of the template more stable.

[0015] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0016] Example 1 like Figures 1 to 3 , Figure 6 and Figure 7As shown, a template surface grinding machine further includes a platform 1, a grinding roller 2, and a chip box 8. A through groove is provided in the middle of the platform 1, and the grinding roller 2 is rotatably mounted in the through groove of the platform 1. The chip box 8 is installed at the bottom of the platform 1 and is used to collect wood chips. It also includes an upper frame 3, a push cylinder 4, a clamping frame 5, two pressure rollers 6, multiple limiting rollers 7, and multiple adjusting components. The upper frame 3 is mounted on the platform 1, and the fixed end of the push cylinder 4 is mounted on the upper frame 3. The lower end of the piston rod of the push cylinder 4 is connected to the clamping frame 5. Two pressure rollers 6 are rotatably mounted at both ends of the clamping frame 5, located on the left and right sides of the grinding roller 2. Multiple limiting rollers 7 are mounted on the clamping frame 5 via multiple adjusting components. These adjusting components are used to adjust the height of the limiting rollers 7, which extend below the two pressure rollers 6 to limit the gap between the pressure rollers 6 and the platform 1. The adjusting components include a sleeve 9, a worm gear 10, a handwheel 11, and a roller mounting rod 12. The sleeve 9 is mounted on the clamping frame 5, and the worm gear 10 is vertically rotatably mounted on... Inside the mounting groove of the sleeve 9, a handwheel 11 is mounted on the upper end of the worm gear 10, and the upper end of the roller mounting rod 12 is slidably inserted into the sliding groove of the sleeve 9. The upper part of the roller mounting rod 12 meshes with the worm gear 10 through the worm teeth, and the lower end of the roller mounting rod 12 is rotatably mounted with a limiting roller 7. It also includes two driven wheels 13, a motor 14, a driving wheel 15, and two transmission belts 16. The two driven wheels 13 are concentrically mounted on the central shafts of the two pressure rollers 6, the motor 14 is mounted on the pressure frame 5, and the driving wheel 15 is mounted on the transmission belt of the motor 14. On the output shaft, one end of each of the two drive belts 16 is fitted onto two driven pulleys 13, and the other end of each of the two drive belts 16 is fitted onto a drive pulley 15. It also includes an air extractor 24 and two breathable sponge strips 25. The air extractor 24 is installed below the platform 1, and the suction end of the air extractor 24 extends into the interior of the debris box 8. Two vertically connected adsorption grooves are provided on the platform 1, and the adsorption grooves are connected to the interior of the debris box 8. The two adsorption grooves are located on the left and right sides of the groove, respectively, and the two breathable sponge strips 25 are installed in the two adsorption grooves.

[0017] According to the thickness of the template, the worm gear 10 is rotated by the handwheel 11. The worm gear 10 engages with the roller mounting rod 12, which moves up and down along the groove of the sleeve 9, thereby adjusting the distance of the limiting roller 7 extending below the pressure roller 6. This distance is the limiting gap. The operation is convenient and has a self-locking function. After adjustment, the position of the limiting roller 7 is stable and reliable. During operation, the piston rod of the push cylinder 4 extends downward, causing the clamping frame 5 and the two pressure rollers 6 to descend, so that multiple limiting rollers 7 are rolled and connected to the platform 1, thereby limiting the gap between the two pressure rollers 6 and the platform 1. The grinding roller 2 rotates at high speed, and the motor 14 drives the drive wheel 15 to rotate. The drive wheel 15 drives the two driven wheels 13 to rotate through two transmission belts 16, and the two driven wheels 13 drive the two pressure rollers respectively. The rollers 6 rotate synchronously and in the same direction, causing the friction template to move on the platform 1. This allows the grinding rollers 2 to perform surface grinding on the template. Compared with existing technologies, this technology can limit the size of the gap between the two rollers 6 and the platform 1, making the gap stable and thus stabilizing the pressure of the two rollers 6 on the template, resulting in a more stable surface grinding effect. The air extractor 24 operates to extract the air from the chip box 8, creating a negative pressure inside the chip box 8. This allows the wood chips ground by the grinding rollers 2 to be sucked into the chip box 8 through the through groove for collection. At the same time, the negative pressure inside the chip box 8 vacuum-adheres the lower surface of the template through the two breathable sponge strips 25, thus making the template adhere tightly to the platform 1 and improving the stability of the template.

[0018] Example 2 like Figure 1 , Figure 2 and Figure 4 As shown, based on Embodiment 1, it further includes two shafts 17, two torsion springs 18, two swing arms 19, and two auxiliary pressure rollers 20. The two shafts 17 are installed opposite each other on both sides of the clamping frame 5. The upper ends of the two swing arms 19 are elastically connected to the two shafts 17 through the two torsion springs 18 respectively. The two auxiliary pressure rollers 20 are rotatably installed at the lower ends of the two swing arms 19 respectively. It also includes two upper pull rods 21 and a telescopic rod 22. The lower ends of the two upper pull rods 21 are connected to the two shafts 17 respectively. The two ends of the telescopic rod 22 are rotatably connected to the two upper pull rods 21 respectively. It also includes two lower support rollers 23. The two lower support rollers 23 are rotatably installed in the through groove of the platform 1. The two lower support rollers 23 are located below the two auxiliary pressure rollers 20 respectively.

[0019] When the telescopic rod 22 extends or retracts, it pushes the two upper pull rods 21 to open or close, thereby driving the two shafts 17 to rotate. Then, the distance of the two auxiliary pressure rollers 20 extending below the two pressure rollers 6 is adjusted by the two swing arms 19 to achieve different auxiliary pressing effects on the template. The torque of the two torsion springs 18 drives the two auxiliary pressure rollers 20 to rotate downward through the two swing arms 19, so that the two auxiliary pressure rollers 20 provide auxiliary pressing on the template in the middle of the two pressure rollers 6. The two lower support rollers 23 cooperate with the two auxiliary pressure rollers 20 to provide rolling support for the template located between the two pressure rollers 6, so as to avoid the template between the two pressure rollers 6 from poor contact with the grinding roller 2 due to lack of pressing force, and improve grinding stability.

[0020] like Figures 1 to 7 As shown, this utility model discloses a template surface grinding machine. During operation, the worm gear 10 is first rotated via handwheel 11 according to the template thickness. The worm gear 10 engages with and drives the roller mounting rod 12 to rise and fall along the slide groove of the sleeve 9, thereby adjusting the distance by which the limiting roller 7 extends below the pressure roller 6. This distance is the limiting gap. Later, during operation, the piston rod of the push cylinder 4 extends downwards, causing the clamping frame 5 and the two pressure rollers 6 to descend, making the multiple limiting rollers 7 roll and connect with the platform 1, thus adjusting the gap between the two pressure rollers 6 and the platform 1. The gap is limited; then the two lower support rollers 23 cooperate with the two auxiliary pressure rollers 20 to roll and support the template located between the two pressure rollers 6. The grinding roller 2 rotates at high speed, and the two pressure rollers 6 rotate synchronously, so that the template moves on the platform 1 by friction, so that the grinding roller 2 performs surface grinding on the lower surface of the template. Finally, the air extractor 24 runs to extract the air inside the chip box 8, so that the inside of the chip box 8 forms a negative pressure, so that the wood chips ground by the grinding roller 2 are sucked into the chip box 8 through the through groove, and the wood chips can be collected.

[0021] The main functions achieved by this utility model are: 1. It can limit the size of the gap between the two pressure rollers 6 and the platform 1, so as to stabilize the gap and thus stabilize the pressure of the two pressure rollers 6 on the template, making the surface grinding effect of the template more stable. 2. The distance by which the limiting roller 7 extends below the pressure roller 6 can be adjusted, making operation convenient and featuring a self-locking function. After adjustment, the position of the limiting roller 7 is stable and reliable. 3. Two lower support rollers 23, together with two auxiliary pressure rollers 20, provide rolling support for the template located between the two pressure rollers 6, thereby improving the grinding stability of the template; 4. The wood chips ground by the grinding roller 2 can be sucked into the chip box 8 through the through groove to collect the wood chips; at the same time, the negative pressure inside the chip box 8 vacuum adsorbs the lower surface of the template through the two breathable sponge strips 25, so that the template is tightly attached to the platform 1 and the stability of the template is improved.
