Description

Technical Field

[0001] This invention relates to the field of cutting and edge-grinding devices, and more particularly to an adjustable cutting and edge-grinding device for PP board production. Background Technology

[0002] PP sheets, as a lightweight, corrosion-resistant, and easy-to-process plastic sheet, are widely used in chemical corrosion protection, environmental protection equipment, packaging and building materials, and other fields. During the PP sheet cutting process, burrs, welded edges, and uneven end faces are easily produced at the cuts. Specialized edge-grinding equipment is usually required to trim the cuts to ensure the quality of the sheet edges and its safety in use.

[0003] Most existing PP board edge grinding devices adopt a double-sided grinding head structure to achieve simultaneous processing of both sides of the board. The width adjustment is generally completed by unidirectional lead screw movement or independent adjustment on both sides. Some equipment uses linear guide rails in conjunction with sliders to achieve lateral positioning of the edge grinding unit, so as to adapt to edge grinding operations of PP boards of different widths.

[0004] The above-mentioned issues have the following drawbacks: the traditional adjustment method cannot achieve synchronous movement of the grinding heads on both sides, which easily leads to problems such as asynchronous adjustment, poor centering, and low positioning accuracy, making it difficult to meet the production needs of rapid and accurate adjustment of PP boards of different widths. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of existing technologies, such as the inability to achieve synchronous movement of the grinding heads on both sides, the easy occurrence of asynchronous adjustment, poor centering, and low positioning accuracy, which make it difficult to meet the production needs of rapid and accurate adjustment of PP boards of different widths. Therefore, an adjustable cutting and grinding device for PP board production is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: It includes an operating table and two mounting columns. Four support columns are fixedly connected to the lower surface of the operating table. A grinding plate is abutted against the upper surface of the operating table. An adjustment structure is provided on the side of the two mounting columns that are close to each other. The adjustment structure includes an adjustment component, a linkage component, and a grinding component. The adjustment component includes a horizontal plate, which is fixedly connected to the side of the two mounting columns that are close to each other. Two mounting seats are fixedly connected to the lower surface of the horizontal plate. Bearings are installed on the inner wall of the mounting seats. A bidirectional lead screw is rotatably connected to the mounting seats via the two bearings. An adjustment motor is installed on the upper surface of the horizontal plate. A drive shaft is fixedly connected to the output end of the adjustment motor. An auxiliary shaft is fixedly connected to the arc surface of the bidirectional lead screw. A drive belt is connected to the drive shaft and the auxiliary shaft for transmission. The screw has two sliding seats threadedly connected to its two threaded surfaces. The linkage assembly includes two linkage seats, which are slidably connected to the bidirectional screw. Each linkage seat has a sliding groove on its two sides. A sliding rod is fixedly connected to the side of the sliding seat near the sliding groove. The sliding rod is slidably connected to the inner wall of the corresponding sliding groove. A linkage column is fixedly connected to the lower surface of the linkage seat. A drive motor is mounted on the lower surface of the linkage seat. The grinding assembly includes two grinding frames, which are fixedly connected to the corresponding linkage columns. Three rotating rods are rotatably connected to the inner wall of each grinding frame. A drive gear is fixedly connected to the arc surface of each of the three rotating rods. A central gear is fixedly connected to the output end of the drive motor. The central gear and the three drive gears mesh with a toothed belt. A grinding wheel is fixedly connected to the end of the rotating rod near the operating table.

[0007] The effect achieved by the above-mentioned components is that the grinding components on both sides can be finely adjusted at the same time by adding an adjustment structure. This can be accomplished simply by controlling the forward and reverse rotation of the adjustment motor. Moreover, the adjustment accuracy is high, which can meet the precise requirements of grinding the edges of PP boards of different specifications, and effectively avoids the problems of cumbersome adjustment and insufficient accuracy of traditional devices.

[0008] Preferably, the two mounting bases are fixedly connected to each other on their adjacent sides by a guide rod, and the two guide rods are slidably connected to two guide seats, with each guide seat being fixedly connected to a corresponding sliding seat.

[0009] The effect achieved by the above components is that the sliding fit between the guide rod and the guide seat provides additional guiding support for the movement of the sliding seat, further restricting the degree of freedom of the sliding seat during the movement process, so that it can only make a smooth linear movement along the axial direction of the guide rod, avoiding radial shaking or torsion of the sliding seat caused by factors such as the thread clearance of the double-acting screw or assembly errors.

[0010] Preferably, two reinforcing plates are fixedly connected to the sides of the two added columns that are close to each other, and the two reinforcing plates are fixedly connected to the cross plate together.

[0011] The effect achieved by the above components is that the addition of the reinforcing plate, the added column, and the horizontal plate form a stable triangular support structure, which effectively enhances the structural strength and load-bearing capacity of the connection between the horizontal plate and the added column.

[0012] Preferably, an upper dust cover is fixedly connected to the upper surface of the horizontal plate, and a lower dust cover is fixedly connected to the lower surface of the horizontal plate.

[0013] The effects achieved by the above components are as follows: the upper and lower dust covers, through their fully enclosed protective design, can effectively prevent dust from adhering to the transmission surface and causing slippage, and avoid mechanical failures caused by debris jamming the transmission gap.

[0014] Preferably, the lower surface of the sliding seat is provided with a fine-tuning structure, which includes a fine-tuning component, an assisting component, and a guiding component. The assisting component includes a long plate, which is fixedly connected to the sliding seat. The long plate and the sliding seat are jointly fixedly connected to two stabilizing plates. A sliding plate is fixedly connected to the end of the long plate away from the sliding seat. The fine-tuning component includes an mounting base, which is fixedly connected to a corresponding sliding plate. The guiding structure includes two first guide grooves, which are formed on the upper surface of the operating table. The inner wall of the guide groove is slidably connected to the mounting base. A guide plate is fixedly connected to the lower surface of the mounting base. Two limiting covers are fixedly connected to the lower surface of the operating table. The guide plate is slidably connected to the bottom wall of the limiting cover. A fine-tuning rod is slidably connected to the mounting base, and the fine-tuning rod is fixedly connected to the grinding frame. A shaft is fixedly connected to the mounting base, and an eccentric disk is rotatably connected to the arc surface of the shaft. A transmission ring is fixedly connected to the side of the eccentric disk near the mounting base. A first short rod is fixedly connected to the end of the fine-tuning rod away from the grinding frame. A rotating frame is rotatably connected to the arc surface of the first short rod, and a roller is rotatably connected to the arc surface of the first short rod. The roller abuts against the arc surface of the transmission ring. A second short rod is fixedly connected to one side of the rotating frame, and an extrusion shaft is rotatably connected to the arc surface of the second short rod. The extrusion shaft abuts against the inner wall of the transmission ring. A positioning cap is threadedly connected to the arc surface of the shaft. A lever is fixedly connected to the side of the eccentric disk away from the mounting base.

[0015] The effect achieved by the above components is that, by adding a fine-tuning structure, a more precise position adjustment of the grinding frame can be achieved on the basis of the overall position adjustment of the grinding frame along with the sliding plate.

[0016] Preferably, a friction ring pad is fixedly connected to the side of the eccentric disk near the positioning cap, and the surface of the friction ring pad is provided with several anti-slip grooves.

[0017] The effect achieved by the above components is that by fixing a friction ring pad to the side of the eccentric disk near the positioning cap and opening several anti-slip grooves on the surface of the friction ring pad, the friction force between the positioning cap and the eccentric disk can be significantly enhanced.

[0018] Preferably, the arc surface of the lever is fixedly connected with an anti-slip sleeve, which is a rubber sleeve.

[0019] The effect achieved by the above components is that by fixing a rubber anti-slip sleeve to the arc surface of the lever, the friction force when the operator holds the lever can be effectively increased.

[0020] Preferably, a strip groove is provided on one side of the eccentric disk, the inner wall of the strip groove is slidably connected to the second short rod, and a plurality of scale grooves are provided on the surface of the eccentric disk.

[0021] The effect achieved by the above components is as follows: by opening a strip groove on one side of the eccentric disk, the second short rod can slide along the inner wall of the strip groove. At the same time, several scale grooves are opened on the surface of the eccentric disk. The operator can intuitively read the rotation angle of the eccentric disk through the scale grooves and the position of the second short rod, so as to achieve precise quantitative adjustment of the position of the grinding frame. This avoids the error of relying on experience judgment in the traditional adjustment method and further improves the convenience of device adjustment and the level of precision control.

[0022] Preferably, the upper surface of the operating table is provided with an auxiliary structure, the auxiliary structure including two second guide grooves, the two second guide grooves are respectively opened on the upper surface of the operating table, the two second guide grooves are slidably connected to a push plate, the push plate abuts against the plate to be ground, the lower surface of the push plate is fixedly connected to a base plate, the side of the push plate away from the grinding component is fixedly connected to an installation tube, the inner wall of the installation tube abuts against an insert, the end of the insert away from the push plate is fixedly connected to a connecting frame, and the connecting frame is rotatably connected to a push rod.

[0023] The effects achieved by the above-mentioned components are as follows: by adding auxiliary structures, the problems of easy PP board displacement and uneven pushing speed during traditional manual pushing are effectively solved, the stability and processing accuracy of the edge grinding process are improved, the intensity of manual operation is reduced, and the overall production efficiency is improved.

[0024] Preferably, a gripping frame is fixedly connected to the end of the push rod away from the connecting frame, and the gripping frame is a tripod.

[0025] The above-mentioned components achieve the following effects: the grip frame adopts a triangular structure design, which not only conforms to the principles of ergonomics and provides operators with a comfortable and stable grip, but also effectively avoids the problem of affecting the pushing accuracy due to hand slippage during the pushing process.

[0026] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this invention, when the regulating motor starts, its output end drives the bidirectional lead screw to rotate synchronously within the bearing of the mounting base via a transmission shaft, transmission belt, and auxiliary shaft. Since the threads on both sides of the bidirectional lead screw rotate in opposite directions, the two sliding seats will move synchronously towards or away from each other along the lead screw. The sliding seats slide in conjunction with the sliding groove of the linkage seat via a sliding rod, thereby driving the two linkage seats and the grinding assembly below to move synchronously, achieving adjustment of the distance between the grinding wheels on both sides. Simultaneously, the guide rod on the linkage seat is slidably connected to the guide seat fixed to the lower surface of the horizontal plate, ensuring that the linkage seat remains horizontally stable during movement and preventing the grinding wheels from shifting. (The last sentence appears to be incomplete and possibly refers to a specific feature or feature.) The plate, along with the added column and horizontal plate, forms a stable triangular support structure, effectively enhancing the structural strength and load-bearing capacity of the connection between the horizontal plate and the added column. The upper and lower dust covers, through their fully enclosed protective design, effectively prevent slippage caused by dust adhering to the transmission surface and avoid mechanical failures caused by debris jamming the transmission gap. By adding an adjustment structure, the grinding components on both sides can be precisely adjusted simultaneously. This can be accomplished simply by controlling the forward and reverse rotation of the adjustment motor, and the adjustment accuracy is high, meeting the precise edge grinding requirements of PP boards of different specifications. This effectively avoids the problems of cumbersome adjustment and insufficient precision of traditional devices.

[0027] 2. In this invention, when the PP board needs to be edge-ground, the drive motor can be started to drive the central gear to rotate, and the toothed belt synchronously drives the three drive gears and the rotating rod to rotate, so that the three grinding wheels on the same grinding frame grind the PP board cut at the same speed in multiple dimensions. From the first grinding wheel near the PP board feeding direction to the third grinding wheel near the push plate, the surface abrasive mesh size increases sequentially, forming a stepped grinding sequence from coarse to fine. When the PP board passes through the three grinding wheels in sequence under the push plate, the grinding wheel with the smaller mesh size first quickly removes large burrs and imperfections at the cut. The flattened section undergoes initial shaping, followed by further finishing of the cut surface with a medium-grit grinding wheel to refine the grinding marks. Finally, the cut is finely polished with the highest-grit grinding wheel, resulting in a smooth and flat PP board cut. By adding a grinding component, the grinding process of the PP board cut can complete three processes—rough grinding, semi-fine grinding, and fine grinding—in a single feed. This not only significantly improves the edge grinding efficiency but also effectively ensures the stability and consistency of the grinding quality, avoiding the problems of low processing efficiency or insufficient surface finish that occur with traditional single-wheel grinding or multi-wheel grinding with the same grit.

[0028] 3. In this invention, when fine-tuning is required, the operator can rotate the lever to drive the eccentric disc to rotate around the central axis. Due to the eccentric setting of the eccentric disc, its rotation will act on the roller and extrusion shaft through the transmission ring. Specifically, the arc surface of the transmission ring abuts against the roller, and the inner wall abuts against the extrusion shaft. The rotation of the eccentric disc will change the contact position between the transmission ring and the roller and extrusion shaft, thereby driving the fine-tuning rod to slide within the mounting base through the first short rod and the rotating frame. The sliding of the fine-tuning rod is directly transmitted to the grinding frame, thereby realizing the small displacement adjustment of the grinding frame in a limited direction. After the adjustment is in place, the positioning cap can be tightened. When the positioning cap is tightened so that it abuts against the friction ring pad, the position of the eccentric disc is fixed by friction, thereby locking the position of the fine-tuned grinding frame and ensuring positional stability during the grinding process. This meets the higher requirements for grinding accuracy when grinding the edges of PP board cuts. The presence of the friction ring pad increases the contact surface. The anti-slip groove further enhances the anti-slip effect, effectively preventing the eccentric disk from rotating unexpectedly due to vibration and other factors during the grinding process. This ensures the long-term stability of the grinding frame position after fine adjustment, further improving the processing accuracy and reliability of PP board edge grinding. The anti-slip sleeve on the arc surface of the lever effectively increases the friction when the operator holds the lever. During the rotation of the eccentric disk, the second short rod can slide along the inner wall of the strip groove. The operator can intuitively read the rotation angle of the eccentric disk through the scale groove and the position of the second short rod, realizing precise quantitative adjustment of the grinding frame position. This avoids the error of relying on experience judgment in the traditional adjustment method, further improving the convenience and precision control level of the device adjustment. By adding a fine adjustment structure, more precise position adjustment of the grinding frame can be achieved on the basis of overall position adjustment of the grinding frame with the sliding plate.

[0029] 4. In this invention, when it is necessary to push the plate to be ground, the insert on the push rod can be inserted into the mounting tube, and then the pushing force is applied with the help of the grip frame. At this time, the cooperation structure between the mounting tube and the insert can ensure a stable connection between the push rod and the plate to be ground, avoiding slippage during the pushing process. At the same time, the arc design of the grip frame conforms to the ergonomic principle, which can effectively distribute hand pressure, making it less tiring for operators to push for a long time, thereby improving the convenience and stability of the overall operation, and further ensuring the accurate feeding of PP board during the edge grinding process. By setting the auxiliary structure, the problems of easy deviation of PP board and uneven pushing speed during traditional manual pushing are effectively solved, improving the stability and processing accuracy of the edge grinding process, while reducing the intensity of manual operation and improving the overall production efficiency.

A push rod 47 is rotatably connected to the connecting frame 46. A grip frame 48 is fixedly connected to the end of the push rod 47 away from the connecting frame 46. The grip frame 48 is a triangular frame. The grip frame 48 adopts a triangular frame structure design, which not only conforms to the ergonomic principle and provides the operator with a comfortable and stable grip, but also effectively avoids the problem of affecting the pushing accuracy due to hand slippage during the pushing process.

[0039] The overall working principle is as follows: when the regulating motor 8 starts, its output end drives the bidirectional lead screw 214 to rotate synchronously in the bearing 213 of the mounting base 212 through the transmission shaft 216, transmission belt 218 and auxiliary shaft 217. Since the threads on both sides of the bidirectional lead screw 214 rotate in opposite directions, the two sliding seats 215 will move synchronously towards or away from each other along the lead screw. The sliding seats 215 slide and engage with the sliding groove 222 of the linkage seat 221 through the sliding rod 223, thereby driving the two linkage seats 221 and the grinding assembly 23 below to move synchronously, realizing the adjustment of the distance between the two grinding wheels 236. At the same time, the guide rod 225 on the linkage seat 221 is slidably connected to the guide seat 226 fixed on the lower surface of the horizontal plate 211, ensuring that the linkage seat 221 remains horizontal and stable during the movement. To prevent the grinding wheel 236 from shifting, the reinforcing plate 219, together with the mounting column 7 and the horizontal plate 211, forms a stable triangular support structure, effectively enhancing the structural strength and load-bearing capacity of the connection between the horizontal plate 211 and the mounting column 7. The upper dust cover 227 and the lower dust cover 228, through a fully enclosed protective design, can effectively prevent dust from adhering to the transmission surface and causing slippage, avoiding mechanical failures caused by debris jamming the transmission gap. By adding the adjustment structure 2, the grinding components 23 on both sides can be finely adjusted simultaneously. This can be accomplished simply by controlling the forward and reverse rotation of the adjustment motor 8, and the adjustment accuracy is high, which can meet the precise requirements of grinding the edges of PP boards of different specifications, effectively avoiding the problems of cumbersome adjustment and insufficient accuracy of traditional devices.

[0040] When the edge of the plate to be ground 5 needs to be ground, the drive motor 9 can be started to drive the central gear 232 to rotate. The gear belt 235 synchronously drives the three drive gears 234 and the rotating rod 233 to rotate, so that the three grinding wheels 236 on the same grinding frame 231 grind the PP plate cut at the same speed in multiple dimensions. From the first grinding wheel 236 near the PP plate feeding direction to the third grinding wheel 236 near the push plate 42, the surface abrasive mesh size increases sequentially, forming a stepped grinding sequence from coarse to fine. When the PP plate passes through the three grinding wheels 236 in sequence under the push of the push plate 42, the smaller mesh size grinding wheel 236 first removes the abrasive particles quickly. Large burrs and uneven parts at the cut are initially shaped. Then, a medium-grit grinding wheel 236 further refines the cut surface, smoothing the grinding marks. Finally, the highest-grit grinding wheel 236 performs fine polishing on the cut, making the PP board cut smooth and flat. By adding the grinding component 23, the grinding process of the PP board cut can complete three processes of rough grinding, semi-fine grinding, and fine grinding in one feed. This not only significantly improves the edge grinding efficiency but also effectively ensures the stability and consistency of the grinding quality, avoiding the problems of low processing efficiency or insufficient surface finish that occur in traditional single-wheel grinding or multi-wheel grinding with the same grit.

[0041] When fine-tuning is required, the operator can rotate the lever 322, causing the eccentric disk 314 to rotate around the axis 313. Due to the eccentric setting of the eccentric disk 314, its rotation will act on the roller 318 and the extrusion shaft 321 through the transmission ring 315. Specifically, the arc surface of the transmission ring 315 abuts against the roller 318, and the inner wall abuts against the extrusion shaft 321. The rotation of the eccentric disk 314 will change the contact position between the transmission ring 315 and the roller 318 and the extrusion shaft 321, and then through the first short rod 316 and the rotating frame 317, it will drive... The fine-tuning rod 312 slides within the mounting base 311. The sliding motion of the fine-tuning rod 312 is directly transmitted to the grinding frame 231, thereby achieving a small displacement adjustment of the grinding frame 231 in a defined direction. After adjustment, the positioning cap 324 can be tightened. When the positioning cap 324 is tightened to abut against the friction ring pad 323, the position of the eccentric disk 314 is fixed using friction, thus locking the finely adjusted position of the grinding frame 231. This ensures stable positioning during the grinding process and meets the higher precision requirements for edge grinding of PP boards. The friction ring... The presence of pad 323 increases the contact area and friction coefficient, while the anti-slip groove 222 further enhances the anti-slip effect, effectively preventing the eccentric disk 314 from rotating unexpectedly due to vibration and other factors during the grinding operation. This ensures the long-term stability of the grinding frame 231 position after fine adjustment, further improving the processing accuracy and reliability of PP board edge grinding. The anti-slip sleeve 325 on the arc surface of the lever 322 can effectively increase the friction when the operator holds the lever 322. During the rotation of the eccentric disk 314, the second short rod 319 can slide along the inner wall of the strip groove 326. The operator can intuitively read the rotation angle of the eccentric disk 314 through the position of the scale groove 334 and the second short rod 319, realizing precise quantitative adjustment of the position of the grinding frame 231. This avoids the error of relying on experience judgment in the traditional adjustment method, further improving the convenience and precision control level of the device adjustment. By adding the fine adjustment structure 3, the grinding frame 231 can be adjusted more precisely based on the overall position adjustment of the grinding frame 231 with the sliding plate 328.

[0042] When it is necessary to push the plate to be ground 5, the insert 45 on the push rod 47 can be inserted into the mounting tube 44, and then the pushing force can be applied with the help of the grip 48. At this time, the cooperation structure between the mounting tube 44 and the insert 45 can ensure a stable connection between the push rod 47 and the plate to be ground 5, and avoid slippage during the pushing process. At the same time, the arc design of the grip 48 conforms to the ergonomic principle, which can effectively distribute the pressure on the hand, so that the operator is not prone to fatigue during long-term pushing operations, thereby improving the convenience and stability of the overall operation, and further ensuring the accurate feeding of PP board during the edge grinding process. By setting the auxiliary structure 4, the problems of easy deviation of PP board and uneven pushing speed during traditional manual pushing are effectively solved, improving the stability and processing accuracy of the edge grinding process, while reducing the intensity of manual operation and improving the overall production efficiency.
