Description

Technical Field

[0001] The invention belongs to the technical field of ceramic production, and in particular relates to a lower enclosure plate machine and a lower enclosure plate method. Background Art

[0002] In the production of foamed ceramics, the function of the enclosure is to enclose a space on the bottom plate to accommodate raw materials. The powder used to burn the foamed ceramics is placed in the space enclosed by the enclosure. After burning, the finished ceramic plate is formed. Then the enclosure needs to be separated from the finished plate to facilitate the next step of unloading the finished plate and cleaning the bottom plate to prepare for the next production. Therefore, the lower enclosure machine is necessary for the production of foamed ceramics.

[0003] The lower panel machine currently used generally uses a chain sprocket mechanism to achieve lifting, and is driven by an ordinary three-phase motor. An additional buffer device needs to be installed between the gripper and the chain to solve the problem of crushing the panel when the gripper descends. However, in actual use, the problems of the existing lower panel machine are still not truly and effectively solved. This is because on the tunnel kiln production line, the bumps during transportation will cause the position of the panel to shift, especially after the ceramic firing is completed, the position of the panel often shifts significantly. Due to the defects of the lifting mechanism of the existing lower panel machine, even with the presence of a buffer device, the panel will still often be crushed.

[0004] In addition, the buffer device itself also has defects. Most of the current buffer devices use hydraulic cylinders as the buffer power source. Therefore, the buffer device needs to be equipped with a complete hydraulic system, such as a hydraulic oil tank, hydraulic pipelines, and cables that run through the entire unloader. Hydraulic fluid leakage in the hydraulic system is inevitable and may occur at any connection point, which means that there are safety hazards in the hydraulic system. When a failure occurs, the maintenance cost is expensive and the downtime is long. In addition, the hydraulic fluid is greatly affected by temperature. In winter, the hydraulic oil is prone to stagnation, resulting in reduced buffer efficiency or even downtime.

[0005] Based on this, the present invention intends to propose a new type of lower enclosure machine to solve the problems existing in the existing lower enclosure. Summary of the invention

[0006] In order to solve the above technical problems, the purpose of the present invention is to provide a lower enclosure panel machine and a lower enclosure panel method. The lower enclosure panel machine has a simple structure, stable operation, and the advantages of a high safety factor. The lifting function and the buffering function are integrated in the lifting mechanism by arranging a steel belt, thereby achieving effective weight reduction of the device, effectively reducing the damage of the enclosure panel caused by the defects of the lower enclosure panel machine itself, and helping to reduce production costs.

DETAILED DESCRIPTION

[0044] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0045] The present invention proposes a lower panel machine, which improves the lifting structure and integrates the lifting and buffering functions. In addition, the present invention also proposes new improvements for the hand clamping part, which, in conjunction with the new lifting structure, effectively solves the problem of easy crushing of the panel. The technical solution of the present invention is described in detail below with a specific structure.

[0046] like Figure 1-9 As shown, the lower enclosure plate machine includes a main frame 1, a steel belt lifting buffer device 2 and an enclosure plate clamping device 3, wherein the steel belt lifting buffer device 2 is arranged in the main frame 1, the enclosure plate clamping device 3 is connected to the steel belt lifting buffer device 2, and the enclosure plate clamping device 3 is controlled to rise and fall by the steel belt lifting buffer device 2.

[0047] The steel belt lifting and buffering device 2 comprises an upper frame 201 , a lower frame 202 and a lifting mechanism. The upper frame 201 is arranged on the main frame 1 , the lifting mechanism is arranged on the upper frame 201 , and the lifting mechanism is connected to the lower frame 202 .

[0048] like Figure 1-5As shown, the lifting mechanism includes a lifting motor 203, a winch 204, a steel belt 209, a guide cylinder 205 and a guide rod 206. The lifting motor 203 is connected to the winch 204, and the lifting motor 203 and the winch 204 are both fixedly arranged on the upper frame 201. One end of the steel belt 209 is wound around the winch 204, and the other end of the steel belt 209 passes through the upper frame 201 and is fixedly connected to the lower frame 202. The guide cylinder 205 is fixedly arranged on the upper frame 201, and the guide cylinder 205 passes through the upper frame 201. One end of the guide rod 206 passes through the guide cylinder 205 and is fixedly connected to the lower frame 202.

[0049] The present invention abandons the conventional hard-linked structure of the sprocket chain, and adopts the soft connection mode of the steel belt 209. The lifting and lowering of the lower frame 202 is realized by the cooperation of the winch 204 and the steel belt 209. Moreover, the steel belt 209 itself can play a buffering role. When the lower frame 202 drops too much and causes the clamping panel device 3 to be obviously pressed on the panel, the panel plays an obvious supporting role on the clamping panel device 3, and the steel belt 209 acts on the steel belt 209, which is manifested as the steel belt 209 being in a relaxed state, so that the lifting motor 203 can detect the torque reduction and can issue an alarm in time. For example, by setting the parameters of the lifting motor 203, the present invention can trigger an alarm when the panel is pressed down by 1-2mm, while the existing lower panel machine needs at least half of the position of the proximity switch, which is about 6-9mm, to trigger the alarm.

[0050] The lifting mechanism controls the lifting and lowering of the lower frame 202, but the steel belt 209 itself is flexible and cannot control the stability of the lower frame 202 during lifting and lowering. The guide rod 206 can effectively prevent the lower frame 202 from shaking during lifting and lowering. Preferably, the number of guide rods 206 is greater than or equal to two. For example, the number of guide rods 206 in the figure is two, and the two guide rods 206 are arranged on both sides of the winch 204. The top of the guide rod 206 can be connected to form a whole through a limit plate 207. It is easy to understand that the number of guide rods 206 and guide cylinders 205 is the same, and the two correspond one to one. Bearings can be arranged in the guide cylinders 205 to reduce the resistance of the guide rods 206 to lift and lower.

[0051] It is easy to understand that the more guide rods 206 there are, the more stable the lower frame 202 is when it is raised or lowered. However, the total weight of the guide rods 206 and the lower frame 202 is greater, which puts higher requirements on the output of the winch 204 and the quality of the steel belt 209. Therefore, the number of guide rods 206 is generally two, three or four.

[0052] The lifting mechanism of the present invention integrates the lifting function and the buffering function through the steel belt 209. Compared with the existing lower enclosure machine, the present invention can omit the original buffering mechanism, achieve overall weight reduction of the device, and is beneficial to saving energy consumption. It is equivalent to that each movement of the lifting motor 203 can save the electric energy originally used to lift part of the weight of the buffering mechanism.

[0053] In the present invention, the upper frame 201 can be connected to the main frame 1 in various ways. For example, the upper frame 201 can be fixedly installed on the main frame 1, or the upper frame 201 can be connected to the main frame 1 through a moving mechanism, that is, the upper frame 201 can be moved on the main frame 1 to adapt to different workplaces.

[0054] Attached Figure 1-3 The figure shows the way in which the upper frame 201 is fixedly connected to the main frame 1. In addition, the present invention also proposes a technical solution for the upper frame 201 to move on the main frame 1, which is not shown in the accompanying drawings. For example, the moving mechanism includes a guide rail, a guide wheel, a guide rack, a motor reducer assembly, a driving shaft and a driving gear. Two guide rails are arranged in parallel on the main frame 1, two sets of guide wheels are arranged at the edge of the upper frame 201, and each set of guide wheels is slidably connected to the guide rails on the same side, two guide racks are arranged in parallel, and the guide racks are parallel to the guide rails, and the guide rails are outside the guide racks. The motor reducer assembly is arranged on the upper frame 201, and two driving shafts are respectively connected to the motor reducer assembly, and a driving gear is arranged at one end of the driving shaft, and the driving gear is meshed with the guide rack on the same side. In this way, the walking of the steel belt lifting buffer device 2 on the main frame 1 is realized, and the clamped enclosure is moved to the station for collecting the enclosure.

[0055] Preferably, the lower frame 202 is provided with a plurality of limit posts 208, and a buffer pad is provided on the top surface of the limit posts 208. The limit posts 208 are arranged upward to prevent the lower frame 202 from rising beyond the limit and directly impacting the upper frame 201 during the lifting process.

[0056] More preferably, a proximity switch may be provided on the top surface of the limiting column 208 to automatically monitor the distance between the lower frame 202 and the upper frame 201 .

[0057] The lines of the equipment between the upper rack 201 and the lower rack 202 can be integrated in the drag chain, which will not be described in detail in the present invention.

[0058] The clamping plate device 3 is arranged at the lower frame 202. The structure of the clamping plate device 3 can be diverse and easy to understand. In the present invention, the steel belt lifting buffer device 2 does not affect the structure of the clamping plate device 3. The steel belt lifting buffer device 2 mainly plays a lifting and buffering role.

[0059] In order to more effectively solve the problem of the lower enclosure plate machine damaging the enclosure plate, the present invention also proposes improvements to the enclosure plate clamping device 3. The improved enclosure plate clamping device 3 cooperates with the steel belt lifting buffer device 2 to more effectively protect the enclosure plate.

[0060] As shown in the figure, the clamping plate device 3 includes a plurality of clamping mechanisms, which are arranged on the edge of the lower frame 202, wherein the clamping mechanism includes an adjusting cylinder 303, a mounting rod 301, a first linear guide pair 305 and a plurality of clamping assemblies 302, the cylinder body of the adjusting cylinder 303 is fixedly connected to the lower frame 202, the end of the piston member of the adjusting cylinder 303 is connected to the mounting rod 301, the linear guide of the first linear guide pair 305 is fixedly arranged on the bottom surface of the lower frame 202, the slider of the first linear guide pair 305 is fixedly arranged on the top surface of the mounting rod 301, the adjusting cylinder 303 controls the mounting rod 301 to move along the first linear guide pair 305, and a plurality of clamping assemblies 302 are arranged on the bottom surface of the mounting rod 301.

[0061] like Figure 6 As shown, in each clamping mechanism, the number of the first linear guide pairs 305 is preferably two, the piston member of the adjusting cylinder 303 is fixedly connected to the top surface of the middle part of the mounting rod 301, and the two first linear guide pairs 305 are respectively located on the left and right sides of the adjusting cylinder 303. It is easy to understand that the extension and retraction direction of the piston member of the adjusting cylinder 303 is consistent with the guiding direction of the first linear guide pair 305.

[0062] Taking the enclosure as an example, the number of gripping mechanisms is four, and the four gripping hands are arranged around the edge of the lower frame 202. When the enclosure clamping device 3 descends, the regulating cylinder 303 first drives the mounting rod 301 to move outward, and avoids the gripping hand assembly 302 from contacting the enclosure as much as possible during the descent process. After descending to the set height, the regulating cylinder 303 controls the mounting rod 301 to move inward, and the gripping hand assembly 302 contacts and clamps the enclosure.

[0063] It is easy to understand that, for situations where the number of panel offsets and the offset distance are small, the panel clamping device 3 can reduce damage to the panel. For panels with larger offset distances, even if the clamping mechanism moves outward to the extreme position, there is a possibility of contact with the offset panel. At this time, the steel belt lifting buffer device 2 plays a precise buffering role when the panel clamping device 3 contacts the panel, effectively preventing the panel clamping device 3 from continuing to press down and causing damage to the panel.

[0064] Preferably, the enclosure plate clamping device 3 further includes an air tank 304 , which is disposed on the lower frame 202 , and the plurality of regulating cylinders 303 are all connected to the air tank 304 .

[0065] Preferably, the piston of the adjusting cylinder 303 is hinged to the mounting rod 301 , so as to provide a certain adjustment space for the movement of the mounting rod 301 .

[0066] The structure of the gripper assembly 302 in the clamping panel device 3 is not limited. Currently, any gripper structure that can clamp the panel is applicable to the present invention. Preferably, the present invention also proposes an improved gripper assembly 302, such as Figure 6 As shown, a buffer assembly is arranged between the gripper assembly 302 and the mounting rod 301, and the buffer assembly includes a sliding base 315, a fixed seat 316 and a buffer spring 318, the fixed seat 316 is fixedly connected to the mounting rod 301, the sliding base 315 is fixedly connected to the gripper assembly 302, the sliding base 315 and the fixed seat 316 are slidably connected, and the buffer spring 318 is arranged between the sliding base 315 and the fixed seat 316, wherein the sliding direction between the sliding base 315 and the fixed seat 316 is the same as the guiding direction of the first linear guide pair 305.

[0067] The function of the buffer assembly is to provide a certain buffer for the contact between the clamping assembly 302 and the enclosure when the mounting rod 301 is controlled to retract by the adjusting cylinder 303. For example, when the enclosure is offset a large distance and is stuck, the clamping assembly 302 is in contact with the enclosure. Even if the mounting rod 301 continues to retract, the buffer assembly provides a buffer distance for the clamping assembly 302, thereby reducing the extrusion of the enclosure by the clamping assembly 302.

[0068] Further, such as Figure 6-9 As shown, the sliding base 315 is provided with a through groove, the fixed seat 316 is provided in the through groove, and the second linear guide pair 317 is provided between the sides of the fixed seat 316 close to the through groove. For example, a slider of the second linear guide pair 317 is provided on the inner side wall of the through groove, and a linear guide of the second linear guide pair 317 is provided on the side of the sliding base 315, and the connection between the sliding base 315 and the fixed seat 316 is realized through the second linear guide pair 317.

[0069] The bottom surface of the fixed seat 316 is open, and a fixed shaft 320 and a moving part 319 are set in the fixed seat 316, and the fixed shaft 320 is parallel to the external second linear guide pair 317, and the buffer spring 318 is sleeved on the fixed shaft 320, and the fixed shaft 320 passes through the moving part 319. The buffer spring 318 is between the moving part 319 and the inner wall of the fixed seat 316, and the moving part 319 is fixedly connected to the sliding base 315.

[0070] In the process of the lower enclosure plate clamping the enclosure plate, theoretically the clamping hand assembly 302 is in contact with the enclosure plate, and the enclosure plate and the clamping hand assembly 302 will not be subjected to squeezing force. However, in actual production, due to the deviation of the enclosure plate position, the enclosure plate is often squeezed by the clamping hand assembly 302, and the clamping hand assembly 302 will also be subjected to reaction force, causing the clamping hand piece 308 thereof to become loose, which is not conducive to production. Furthermore, the present invention also proposes improvements to the gripper assembly 302. Specifically, the gripper assembly 302 includes a clamping cylinder 306, a gripper piece 308, a connecting piece 310, a connecting shaft 311, a connecting rod piece 309 and a mounting frame 307. The clamping cylinder 306 is arranged in the mounting frame 307. The piston of the clamping cylinder 306 is fixedly connected to the connecting piece 310. Two connecting shafts 311 are symmetrically arranged on both sides of the connecting piece 310. The connecting shaft 311 passes through the mounting frame 307, and a limiting portion is provided at one end of the connecting shaft 311. Two self-locking nuts 321 are provided at the other end of the connecting shaft 311. There is a gap between the self-locking nuts 321 and the mounting frame 307. One end of the gripper piece 308 is in the mounting frame 307 and the connecting shaft 311 passes through the gripper piece 308. One end of the connecting rod piece 309 is hinged to the gripper piece 308, and the other end of the connecting rod piece 309 is hinged to the connecting piece 310. The clamping cylinder 306 is connected to the gas storage tank 304 .

[0071] Since there is a gap between the limiting nut and the mounting frame 307, the connecting shaft 311 and the mounting frame 307 are movable. Even if the clamping member 308 presses against the connecting shaft 311 during rotation, the connecting shaft 311 can rotate with it, and the limiting nut will not be loosened due to external force.

[0072] It is easy to understand that the circumferential side surface of one end of the connecting shaft 311 that is provided with the self-locking nut 321 is a threaded surface so that it can be connected to the self-locking nut 321, which is not elaborated in the present invention.

[0073] Further, such as Fig. 9 As shown, a wear-resistant sleeve 312 and a positioning sleeve 313 are also arranged between the gripper 308 and the connecting shaft 311. The wear-resistant sleeve 312 passes through the gripper 308, and the wear-resistant sleeve 312 and the gripper 308 are interference fit. Two positioning sleeves 313 are respectively arranged at both ends of the wear-resistant sleeve 312, and the positioning sleeve 313 is located between the end of the wear-resistant sleeve 312 and the inner wall of the adjacent mounting frame 307. The connecting shaft 311 passes through the wear-resistant sleeve 312 and the two positioning sleeves 313, and the connecting shaft 311 is gap-connected with the wear-resistant sleeve 312 and the positioning sleeve 313. The gripper 308 is in direct contact with the wear-resistant sleeve 312. When the gripper 308 rotates, the wear-resistant sleeve 312 and the connecting shaft 311 actually rotate relative to each other. The two positioning sleeves 313 are used to limit the gripper 308 and prevent the gripper 308 from deviating too much along the axial direction of the connecting shaft 311.

[0074] In addition, the positioning sleeve 313 also helps to prevent the clamping piece 308 from loosening. The reason is that when the clamping piece 308 is affected by external force and causes the wear-resistant sleeve 312 to tend to abut the connecting shaft 311, the wear-resistant sleeve 312 is restricted by the positioning piece, that is, the wear-resistant sleeve 312 will apply force to the positioning sleeve 313 on one side, so that the positioning sleeve 313 will also press the inner wall of the adjacent mounting frame 307. Therefore, the wear-resistant sleeve 312 transfers the force that originally affects the connecting shaft 311 to the adjacent positioning sleeve 313. At this time, the clamping piece 308 can still rotate, but it encounters greater resistance, and the influence of the positioning sleeve 313 and the wear-resistant sleeve 312 on the connecting shaft 311 is reduced, thereby effectively preventing the connecting shaft 311 from loosening.

[0075] Preferably, a gasket 314 is provided between the limiting portion of the connecting shaft 311 and the mounting frame 307 .

[0076] Preferably, a pad is provided on the clamping portion of the gripping member 308 to increase the friction between the gripping member 308 and the enclosure.

[0077] The present invention also proposes a method for lowering the enclosure plate, which is implemented by the above-mentioned lower enclosure plate machine, as follows:

[0078] S1, the lifting mechanism in the steel belt lifting buffer device 2 controls the lower frame 202 to descend by releasing the steel belt 209. During the descent process, multiple gripping mechanisms of the clamping panel device 3 extend outward to avoid the panel below;

[0079] If the clamping device 3 abuts against the top surface of the enclosure, the enclosure supports the clamping device 3, so that the steel belt 209 is gradually relaxed, so as to prevent the lower frame 202 from continuing to press down and causing damage to the enclosure. At the same time, the lifting mechanism continues to release the steel belt 209 until the lifting motor 203 in the lifting mechanism detects that the output torque decreases and reaches the warning value, the lifting mechanism stops and sounds an alarm;

[0080] If the apron clamping device 3 never contacts the apron top surface or the lifting motor 203 detects that the output torque reduction never reaches the warning value, then go to step S2;

[0081] S2, after the lower frame 202 is lowered into position, the multiple gripping mechanisms of the clamping panel device 3 are retracted, so that the gripping assembly 302 is in contact with the ribs on the outer side of the panel;

[0082] During the retraction process of the gripping mechanism, the buffer assembly between the gripping assembly 302 and the mounting rod 301 provides a certain moving distance for the gripping assembly 302, thereby reducing the large squeezing force generated by the gripping assembly 302 from the outer side of the enclosure plate to the enclosure plate;

[0083] S3, after the multiple gripping mechanisms are retracted into position, the multiple gripping assemblies 302 in each gripping mechanism grip the ribs of the corresponding enclosure one by one;

[0084] S4. The lifting mechanism controls the lower frame 202 to rise, so that all the enclosure panels are separated from the finished panels and leave the production line.
