Description

Technical Field

[0001] The present invention relates to the technical field of roller grinding equipment, and in particular to a general grinding device for zero - parts rollers of carding machines. Background Art

[0002] As a key equipment for fiber carding in the textile industry, various rollers inside the carding machine (such as cylinder, doffer, licker - in, etc.) play a crucial role during the operation of the machine. The quality of these components directly affects the carding effect, working efficiency, and the quality of the final product. With the increase of usage time, the surface of the rollers will gradually wear or be damaged due to continuous friction with fiber materials, thus affecting the machine performance. Therefore, regularly grinding and repairing the rollers of the carding machine is an important measure to maintain its efficient operation.

[0003] For some rollers that are easy to disassemble, they can be placed on a dedicated grinding machine for repair. However, not all rollers are easy to disassemble; due to structural limitations or installation methods, some rollers in key positions cannot be easily removed, which makes it difficult for traditional grinding machines to access and effectively grind and repair them. For such rollers that are not easy to disassemble, the current practice is usually to manually hold sandpaper or a hand - held grinding machine for on - site grinding and repair. Although this method is feasible, it has low efficiency, and due to the limitations of the operating environment and the consistency problem of manual operation, the grinding quality and effect may not be satisfactory.

Those skilled in the art can make some non - essential improvements and adjustments to the present application according to the above application content.

[0032] See Figures 1-5, a general grinding device for zero - matching roller parts of a carding machine, including a base 1. On the right side of the top of the base 1, a mounting plate 2 is installed. A three - jaw chuck one 3 is rotatably connected to the mounting plate 2. On the right side of the mounting plate 2, a driving motor 4 for driving the three - jaw chuck one 3 to rotate is installed. On the top of the base 1, an electric slide rail one 5 is installed on the left side of the mounting plate 2. The slider of the electric slide rail one 5 is connected to an L - shaped movable plate one 6. On the top of the movable plate one 6, an electric slide rail two 61 is installed. The slider of the electric slide rail two 61 is connected to a movable plate two 7. On the front side of the movable plate two 7, a three - jaw chuck two 8 coaxial with the three - jaw chuck one 3 is rotatably connected. The specification of the three - jaw chuck two 8 is smaller than that of the three - jaw chuck one 3. A mobile grinding machine 9 is arranged on the base 1. The mobile grinding machine 9 includes two connecting frames 91 respectively arranged on the left and right sides of the base 1. At the front and back of the bottom of the connecting frame 91, two wheels 92 are symmetrically arranged. Vertical grooves are opened on both connecting frames 91. A gantry 93 is slidably connected between the two connecting frames 91 through the vertical grooves. Guide rods 94 are connected to the left rear side of the left connecting frame 91 and the front and back sides of the right part of the right connecting frame 91. The guide rods 94 penetrate through the gantry 93 to guide the lifting of the gantry 93. On the left front side of the left connecting frame 91, a lead - screw motor one 95 is arranged. The lead - screw on the lead - screw motor one 95 is threadedly connected to the gantry 93 to drive the gantry 93 to lift. A chute is opened on the top of the gantry 93. A T - shaped inverted slide plate 96 is slidably connected in the chute. A short abrasive belt 97 for grinding the roller part is arranged on the slide plate 96. On the front and back sides of the slide plate 96, locking parts one 98 are arranged to lock the short abrasive belt 97 on the slide plate 96. The locking part one 98 includes a pressing plate 982 connected to the slide plate 96 through a cloth strip 981. On the left and right sides of the pressing plate 982, fastening bolts 983 for locking it on the slide plate 96 are arranged. Through holes matching the fastening bolts 983 are opened on the short abrasive belt 97. A short rubber block 99 for supporting the short abrasive belt 97 is connected to the bottom of the slide plate 96. A driving component is arranged on the upper part of the gantry 93 to drive the slide plate 96 to drive the short abrasive belt 97 to reciprocate left and right to grind the roller part. The driving component includes a lead - screw motor two 910 arranged on the upper part of the gantry 93. The lead - screw on the lead - screw motor two 910 is threadedly connected to the T - shaped inverted slide plate 96 to drive the slide plate 96 to reciprocate left and right. Two perforated plates 911 are slidably connected in the chute on the top of the gantry 93. The two perforated plates 911 are located outside the slide plate 96 and are slidably sleeved on the lead - screw of the lead - screw motor two 910. On the lower part of the side of the two perforated plates 911 close to each other, buttons 912 are installed. The buttons 912 are electrically connected to the motor on the lead - screw motor two 910. The movement of the slide plate 96 can press the buttons 912. On the upper part of the perforated plate 911, a fastening bolt 913 for locking it on the gantry 93 is arranged. Locking components for locking the connecting frames 91 are arranged on the left and right sides of the base 1. The locking component includes an L - shaped plate 101 connected to the lower part of the side of the base 1. Two clamping balls 102 are slidably connected to the L - shaped plate 101.A first spring 103 is connected between the ball 102 and the L-shaped plate 101. On the lower part of the back side of the connecting frame 91 facing away from the base 1, there are two front and rear card holes 104 that match the ball 102, and the shape of the card hole 104 is hemispherical.

[0033] Initially, the connecting frame 91 is located inside the L-shaped plate 101, and the ball 102 is inserted into the card hole 104 on the connecting frame 91 to lock the connecting frame 91, thereby locking the entire mobile grinding machine 9 on the base 1 to prevent the mobile grinding machine 9 from automatically displacing during the subsequent grinding of the roller, which may affect the grinding of the roller. Place the roller removed from the carding machine on the first three-jaw chuck 3. Subsequently, control the first electric slide rail 5 to drive the first movable plate 6 to drive the second electric slide rail 61 to move to the right, thereby driving the second three-jaw chuck 8 to move to the right through the second movable plate 7. The second three-jaw chuck 8 can be driven to move left and right through the second electric slide rail 61 to adapt to rollers of different length specifications. Then, make the first three-jaw chuck 3 and the second three-jaw chuck 8 clamp the connecting shaft on the roller. The three-jaw chuck is a prior art and will not be elaborated here. Then, control the first lead screw motor 95 to rotate to drive the gantry 93 to move downward, so that the slide plate 96 drives the short abrasive belt 97 to move downward to contact the roller. Subsequently, control the drive motor 4 to drive the first three-jaw chuck 3 to drive the roller to rotate, and the rotating roller is ground and repaired by the short abrasive belt 97. At the same time, control the second lead screw motor 910 to rotate forward to drive the slide plate 96 to drive the short abrasive belt 97 to move to the left. When the slide plate 96 moves to the left and presses the button 912 on the left opening plate 911, the left button 912 controls the second lead screw motor 910 to reverse, so as to drive the slide plate 96 to drive the short abrasive belt 97 to move to the right. When the slide plate 96 moves to the right and presses the button 912 on the right opening plate 911, the right button 912 controls the second lead screw motor 910 to rotate forward. In this way, the short abrasive belt 97 can move left and right reciprocally to achieve comprehensive grinding of the roller. The distance between the two opening plates 911 can be adjusted according to the length of the roller, thereby adjusting the distance between the two buttons 912 to adapt to rollers of different length specifications. Loosen the fastening bolt 913 to unlock the opening plate 911 to adjust the distance between the two opening plates 911 and the two buttons 912. Tighten the fastening bolt 913 to re-lock the opening plate 911 to prevent the opening plate 911 from being displaced by the slide plate 96. After the roller is ground once, loosen the fastening bolt 983 on the first locking member 98 to unlock the pressing plate 982 on the first locking member 98, thereby unlocking the short abrasive belt 97 to facilitate the replacement of the short abrasive belt 97. Then, use a short abrasive belt 97 with a finer particle size to grind the roller again, so as to achieve rough grinding, medium grinding, and fine grinding of the roller in sequence. Through such a step-by-step grinding method, the surface quality of the roller can be effectively repaired and improved, and good carding performance can be maintained. Tighten the fastening bolt 983 on the first locking member 98 to re-lock the pressing plate 982 on the first locking member 98 on the slide plate 96 to press and fix the short abrasive belt 97 on the slide plate 96.

[0034] When it is necessary to polish and repair the rollers on the carding machine that are difficult to disassemble, pull the connecting frame 91 forward from the L-shaped plate 101. During this process, the hemispherical clamping hole 104 on the connecting frame 91 squeezes the clamping ball 102 into the L-shaped plate 101, compressing the first spring 103, so that the locking of the connecting frame 91 can be easily released. Then control the first lead screw motor 95 to rotate to drive the gantry 93 to move downward, so that the sliding plate 96 drives the short abrasive belt 97 to move downward to contact the roller on the carding machine. Subsequently, adjust the distance between the two opening plates 911 and the two buttons 912 according to the length of the roller on the carding machine, so as to avoid hitting the carding machine when the sliding plate 96 drives the short abrasive belt 97 to reciprocate left and right to polish the roller on the carding machine. Drive the roller to rotate through the carding machine, and the rotational polishing of the roller can be realized. In this way, this device can not only automatically polish and repair the rollers that are easy to disassemble through the mobile grinding machine 9, but also conveniently polish and repair the rollers on the carding machine that are difficult to disassemble, greatly enhancing the operation convenience and safety when dealing with the rollers that are not easy to disassemble, and significantly improving the convenience and efficiency of equipment maintenance in the textile industry.

[0035] See Figure 3 , an arc-shaped connecting block 111 is connected to the upper surface of the inverted T-shaped sliding plate 96. The front side of the bottom of the connecting block 111 is connected with a short dust suction hood 112 located in front of the sliding plate 96, and a hose 113 is communicated with the short dust suction hood 112.

[0036] Connect the hose 113 to an external air extraction device. When the sliding plate 96 drives the short abrasive belt 97 to move and polish the roller, control the air extraction device to work, and the debris and dust generated during polishing can be timely sucked into the short dust suction hood 112 and transported to a designated collection location by the air extraction device, effectively preventing the debris and dust from spreading everywhere, reducing its impact on the surrounding environment, and protecting the health of the staff.

[0037] See Figures 6-11, a grinding mechanism is provided on the base 1. The grinding mechanism includes two sets of hydraulic cylinders 121 installed on the inner bottom surface of the base 1, with two hydraulic cylinders 121 in each set. The two hydraulic cylinders 121 in each set are arranged left and right. An arc-shaped plate 122 located above the base 1 is connected between the piston rods of the two sets of hydraulic cylinders 121. Two arc-shaped sliding grooves are formed on the arc-shaped plate 122. Arc-shaped sliders 123 are slidably connected in both of the two arc-shaped sliding grooves. Three telescopic blocks 124 are connected to the top of the arc-shaped slider 123 at intervals along the length extension direction thereof. The telescopic blocks 124 on the two arc-shaped sliders 123 correspond one by one. Long plates 125 located inside the arc-shaped plate 122 are connected between the left and right corresponding telescopic blocks 124. A long abrasive belt 127 for the grinding roller is provided on the long plate 125. Locking members II 128 are provided on the front and rear sides of the long plate 125 for locking the long abrasive belt 127 on the long plate 125. The structure of the locking member II 128 is the same as that of the locking member I 98. A long rubber block 126 for supporting the long abrasive belt 127 is connected to the top of the long plate 125. The particle sizes of the three long abrasive belts 127 from back to front are gradually thickened. Arc-shaped slide rails 1210 are connected to the sides of the two arc-shaped sliders 123 close to each other. Arc-shaped top blocks 1211 are slidably connected in both of the two arc-shaped slide rails 1210. The arc-shaped slide rails 1210 and the arc-shaped top blocks 1211 are both located inside the arc-shaped plate 122. The two arc-shaped top blocks 1211 are connected by a T-shaped plate 1212. An arc-shaped guide groove for the front and rear sliding of the T-shaped plate 1212 is formed on the arc-shaped plate 122. A spring II 1213 is connected between the long plate 125 and the arc-shaped slider 123. Two clamping members 129 are provided on the arc-shaped plate 122. The left clamping member 129 is used to lock the T-shaped plate 1212, and the right clamping member 129 is used to lock the right arc-shaped slider 123. The clamping member 129 includes a sliding plate 1291 slidably connected to the arc-shaped plate 122. The shape of the sliding plate 1291 is arc-shaped. An external threaded rod 1292 is connected to the rear side of the sliding plate 1291. An internal threaded rod 1293 is threadedly connected to the external threaded rod 1292. A hollow rubber top block 1294 is connected to the front end of the internal threaded rod 1293. The sliding plate 1291 on the right clamping member 129 is fixedly connected to the right arc-shaped slider 123 and is slidably connected in the right arc-shaped sliding groove. The sliding plate 1291 on the left clamping member 129 is fixedly connected to the T-shaped plate 1212 and is slidably connected in the arc-shaped guide groove.

[0038] The roller part which is shorter than the long abrasive belt 127 removed from the carding machine can be fixed on the three-jaw chuck 1 3 and the three-jaw chuck 2 8, and then the hydraulic cylinder 121 is controlled to drive the arc plate 122 to drive the upper part thereof to move upward, so that the long abrasive belt 127 moves upward and close to the roller part. Then the internal threaded rod 1293 on the two clamps 129 is rotated so that the internal threaded rod 1293 drives the rubber top block 1294 thereon to disengage from the arc plate 122 backward, so as to release the lock of the sliding plate 1291 on the clamp 129, thereby releasing the lock of the arc slider 123, the T-shaped plate 1212 and the arc top block 1211. Then, the arc-shaped slider 123 is moved forward to drive the telescopic block 124, the long plate 125, the long rubber block 126, the long sanding belt 127, the second locking member 128, the clamp 129, the arc-shaped slide rail 1210, the arc-shaped top block 1211, the T-shaped plate 1212 and the second spring 1213 to move forward, and the front-end long sanding belt 127 moves forward to the lower side of the roller. Then, the internal threaded rod 1293 on the right clamp 129 is reversed, so that the right internal threaded rod 1293 drives the rubber top block 1294 on it to move forward and closely contact the arc plate 122, and the internal threaded rod 1293 is locked by the friction between the rubber top block 1294 and the arc plate 122, thereby locking the external threaded rod 1292 through the internal threaded rod 1293, and then locking the sliding plate 1291. After the right sliding plate 1291 is locked, the right arc-shaped slider 123 is locked to prevent the long plate 125 from driving the long sanding belt 127 to move forward and backward by itself, which affects the subsequent grinding of the roller. Then the left clamp 129 is moved forward continuously, so that the T-shaped plate 1212 drives the arc-shaped top block 1211 to continue to move forward and contact the frontmost long plate 125, and the frontmost long plate 125 is pushed upward by the arc-shaped top block 1211, so that the long sanding belt 127 on the frontmost long plate 125 contacts the roller, and the frontmost spring 2 1213 is stretched accordingly, and the frontmost telescopic block 124 is extended accordingly. Then, the internal threaded rod 1293 on the left clamp 129 is reversed so that the left internal threaded rod 1293 drives the rubber top block 1294 on it to move forward and close to the arc plate 122, thereby locking the left sliding plate 1291, and then locking the T-shaped plate 1212, and finally locking the arc top block 1211, to prevent the long plate 125 from driving the long sanding belt 127 to move down by itself, affecting the subsequent grinding of the roller. Then, the driving motor 4 is controlled to drive the three-claw chuck 13 to drive the roller to rotate and be grinded by the front-end long sanding belt 127. In this way, the device can grind the disassembled roller while the mobile grinder 9 grinds the roller that is difficult to disassemble in the carding machine, thereby improving work efficiency. By repeating the above operation, the three long sanding belts 127 from the front to the back can grind the roller in turn. Since the particle sizes of the three long sanding belts 127 from the back to the front are successively coarsened, the coarse grinding, medium grinding and fine grinding of the roller can be achieved in turn. Through such a step-by-step grinding method, the quality of the roller surface can be effectively repaired and improved, and good combing performance can be maintained.Loosen the fastening bolt 983 on the second locking member 128, and the locking of the pressing plate 982 on the second locking member 128 can be released, so that the locking of the long abrasive belt 127 can be released, facilitating the replacement of the long abrasive belt 127. Tighten the fastening bolt 983 on the second locking member 128, and the pressing plate 982 on the second locking member 128 can be locked on the long plate 125 again to press and fix the long abrasive belt 127 on the long plate 125.

[0039] See Figure 6 、 Figure 12 and Figure 13 , a dust suction mechanism is provided on the front side of the arc-shaped plate 122. The dust suction mechanism includes an arc-shaped rotating plate 131 hinged on the front side of the arc-shaped plate 122. Two springs three 134 are connected to the rear side of the arc-shaped rotating plate 131. A cross plate 135 is connected between the rear ends of the two springs three 134. Two chutes are opened on the front side of the cross plate 135. Sliding blocks 136 are slidably connected in the two chutes. Connecting plates 137 are hinged on the two sliding blocks 136. The front ends of the connecting plates 137 are hinged on the arc-shaped rotating plate 131. The lower part of the rear side of the cross plate 135 is connected with a long dust suction hood 138. The upper part of the rear side of the cross plate 135 is connected with a sponge block 14. The width of the sponge block 14 is greater than that of the long dust suction hood 138. A C-shaped block one 130 is connected to the left side of the arc-shaped rotating plate 131. A C-shaped block two 139 for clamping the C-shaped block one 130 is rotatably connected to the left front side of the arc-shaped plate 122. A dust collector 132 is provided on the front side inside the base 1. The dust collector 132 is communicated with the long dust suction hood 138 through a dust suction pipe 133. The dust collector 132 is a prior art and will not be described in detail here.

[0040] After the roller is fixed on the three-jaw chuck 1 and the three-jaw chuck 2, rotate the arc-shaped rotating plate 131 backward, drive the cross plate 135 to rotate backward through the third spring 134, and the first C-shaped block 130, the sliding block 136, the connecting plate 137, the long dust suction hood 138 and the sponge block 14 rotate backward accordingly. When the sponge block 14 rotates to contact the roller, the sponge block 14, the cross plate 135, the long dust suction hood 138 and the sliding block 136 cannot continue to rotate backward. Thus, the arc-shaped rotating plate 131 continues to move backward to compress the third spring 134 and push the connecting plate 137 to swing, and the sliding block 136 slides in the chute on the cross plate 135, so as to adapt to rollers of different diameters. Then, the second C-shaped block 139 is rotated into the first C-shaped block 130 to lock the arc-shaped rotating plate 131. When the roller fixed on the three-jaw chuck 1 and the three-jaw chuck 2 rotates and is polished by the long abrasive belt 127, the sponge block 14 can scrape off the debris and dust adhering to the roller, realizing automatic cleaning of the roller. Control the vacuum cleaner 132 to work, and the debris and dust can be sucked into the long dust suction hood 138. Then, the debris and dust are conveyed to the vacuum cleaner 132 through the dust suction pipe 133 for collection, effectively preventing the debris and dust from spreading everywhere, reducing its impact on the surrounding environment, and protecting the health of the staff. Rotate the second C-shaped block 139 out of the first C-shaped block 130 to unlock the arc-shaped rotating plate 131, and then the arc-shaped rotating plate 131 can drive the components thereon to rotate forward and reset, so as to facilitate the subsequent removal of the polished roller.
