Description

TECHNICAL FIELD

[0001] The utility model belongs to ceramic production technical field, and specifically relates to a lower baffle machine. BACKGROUND

[0002] In the production of foamed ceramic, the function of the baffle is to form a space for accommodating raw materials on the bottom plate, and the powder for sintering foamed ceramic is placed in the space formed by the baffle, and after sintering, a ceramic finished plate is formed, and then the baffle needs to be separated from the finished plate to facilitate the unloading of the finished plate and the cleaning of the bottom plate for the next production. Therefore, the lower baffle machine is necessary in the production of foamed ceramic.

[0003] The current lower baffle machine generally uses a chain and sprocket mechanism to achieve lifting, and a common three-phase motor is used for driving. An additional buffer device needs to be installed between the gripper and the chain to solve the problem of crushing the baffle when the gripper is lowered. However, in actual use, the existing lower baffle machine still has problems that cannot be truly and effectively solved. This is because the jolting that occurs during transportation on the tunnel kiln production line can cause the position of the baffle to deviate, especially after the ceramic is sintered, the position of the baffle often deviates significantly. Due to the defects of the lifting mechanism of the existing lower baffle machine, even with the buffer device, the baffle is still often 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 unloading machine. Hydraulic fluid leakage of the hydraulic system is inevitable and can occur at any connection point, i.e. the hydraulic system has safety hazards. When a fault occurs, the repair cost is high and the downtime is long. In addition, hydraulic fluid is greatly affected by temperature. In winter, the hydraulic oil can easily solidify, resulting in reduced buffer efficiency or even shutdown.

[0005] Based on this, the utility model intends to provide a new type of lower baffle machine to solve the problems existing in the current lower baffle machine. UTILITY MODEL CONTENTS

[0044] The lifting mechanism controls the lifting 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 the guide rods 206 can effectively prevent the lower frame 202 from shaking during lifting. Preferably, the number of guide rods 206 is greater than or equal to two, such as 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 end of the guide rod 206 can be connected by the limiting plate 207 to form a whole.

Bearings can be arranged in the guide cylinder 205 to reduce the lifting resistance of the guide rod 206.

[0045] It is easy to understand that the more guide rods 206, the more stable the lower frame 202 during lifting, but the total weight of the guide rod 206 and the lower frame 202 is larger, which puts higher requirements on the output of the winch 204 and the quality of the steel belt 209.

Thus, the steel belt lifting and buffering device 2 can move on the total frame 1, and the clamped coaming can be moved to the coaming collecting station.

[0049] Preferably, the lower rack 202 is provided with a plurality of limiting posts 208, and the top surface of the limiting post 208 is provided with a buffer pad. The limiting post 208 is upwardly arranged, and is used for preventing the distance of the lower rack 202 from being too long during lifting, and directly impacting the upper rack 201.

[0050] More preferably, the top surface of the limiting post 208 is also provided with a proximity switch, and the distance between the lower rack 202 and the upper rack 201 is automatically monitored.

[0051] The lines of the equipment between the upper rack 201 and the lower rack 202 can be integrated in a drag chain, and the utility model will not be described in detail.

[0052] The clamping and surrounding plate device 3 is arranged at the lower rack 202, and the structure of the clamping and surrounding plate device 3 can be various. It is easy to understand that the steel belt lifting and buffering device 2 does not affect the structure of the clamping and surrounding plate device 3 in the utility model, and the steel belt lifting and buffering device 2 mainly plays a lifting and buffering role.

[0053] In order to more effectively solve the problem of the damage of the surrounding plate by the lower surrounding plate machine, the utility model also improves the clamping and surrounding plate device 3, and the improved clamping and surrounding plate device 3 cooperates with the steel belt lifting and buffering device 2, so that the surrounding plate can be more effectively protected.

[0054] As shown in the figure, the clamping and surrounding plate device 3 comprises a plurality of clamping hand structures, and the clamping hand structure is arranged at the edge of the lower rack 202. The clamping hand structure comprises an adjusting cylinder 303, a mounting rod 301, a first linear guide rail pair 305 and a plurality of clamping hand assemblies 302. The cylinder body of the adjusting cylinder 303 is fixedly connected with the lower rack 202, the piston end of the adjusting cylinder 303 is connected with the mounting rod 301, the linear guide rail of the first linear guide rail pair 305 is fixedly arranged on the bottom surface of the lower rack 202, the sliding block of the first linear guide rail 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 rail pair 305, and the plurality of clamping hand assemblies 302 are arranged on the bottom surface of the mounting rod 301.

[0055] As shown in the figure, the clamping and surrounding plate device 3 comprises a plurality of clamping hand structures, and the clamping hand structure is arranged at the edge of the lower rack 202. The clamping hand structure comprises an adjusting cylinder 303, a mounting rod 301, a first linear guide rail pair 305 and a plurality of clamping hand assemblies 302. The cylinder body of the adjusting cylinder 303 is fixedly connected with the lower rack 202, the piston end of the adjusting cylinder 303 is connected with the mounting rod 301, the linear guide rail of the first linear guide rail pair 305 is fixedly arranged on the bottom surface of the lower rack 202, the sliding block of the first linear guide rail 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 rail pair 305, and the plurality of clamping hand assemblies 302 are arranged on the bottom surface of the mounting rod 301. Figure 6 As shown in the figure, the clamping and surrounding plate device 3 comprises a plurality of clamping hand structures, and the clamping hand structure is arranged at the edge of the lower rack 202. The clamping hand structure comprises an adjusting cylinder 303, a mounting rod 301, a first linear guide rail pair 305 and a plurality of clamping hand assemblies 302. The cylinder body of the adjusting cylinder 303 is fixedly connected with the lower rack 202, the piston end of the adjusting cylinder 303 is connected with the mounting rod 301, the linear guide rail of the first linear guide rail pair 305 is fixedly arranged on the bottom surface of the lower rack 202, the sliding block of the first linear guide rail 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 rail pair 305, and the plurality of clamping hand assemblies 302 are arranged on the bottom surface of the mounting rod 301.

[0056] For example, the square space surrounded by the fence, the number of clamping hand structure is four, four clamping hand around the edge of the lower frame 202 is set. When the fence clamping device 3 is lowered, the adjusting cylinder 303 first drives the mounting rod 301 to move outward, to avoid the contact between the clamping hand assembly 302 and the fence during the lowering process as far as possible, after lowering to the set height, the adjusting cylinder 303 controls the mounting rod 301 to move inward, the clamping hand assembly 302 contacts and clamps the fence.

[0057] It is easy to understand that for the fence offset number is less and the offset distance is small, the fence damage can be reduced by the fence clamping device 3, for the fence with large offset distance, even if the clamping hand structure is moved to the limit position, there is a possibility of contact with the offset fence, at this time, the steel belt lifting buffer device 2 plays an accurate buffering role when the fence clamping device 3 contacts the fence, effectively avoiding the fence damage caused by the continuous pressing of the fence clamping device 3.

[0058] Preferably, the fence clamping device 3 further comprises a gas storage tank 304, and the gas storage tank 304 is arranged on the lower frame 202, and the plurality of adjusting cylinders 303 are connected with the gas storage tank 304.

[0059] Preferably, the piston of the adjusting cylinder 303 is hinged with the mounting rod 301, so as to provide a certain adjustment space for the movement of the mounting rod 301.

[0060] The structure of the clamping hand assembly 302 in the fence clamping device 3 is not limited, and at present, as long as the clamping hand structure capable of clamping the fence is suitable for the utility model. Preferably, the utility model also proposes an improved clamping hand assembly 302, as shown in Figure 6 The buffer assembly is arranged between the clamping hand assembly 302 and the mounting rod 301, the buffer assembly comprises a sliding base 315, a fixed seat 316 and a buffer spring 318, the fixed seat 316 is fixedly connected with the mounting rod 301, the sliding base 315 is fixedly connected with the clamping hand 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 rail pair 305.

[0061] The function of the buffer assembly is to provide a certain buffer for the contact between the clamping hand assembly 302 and the fence when the mounting rod 301 is controlled to retract by the adjusting cylinder 303, for example, when the fence offset distance is large and is stuck, the clamping hand assembly 302 contacts the fence, even if the mounting rod 301 continues to retract, the buffer assembly provides a buffer distance for the clamping hand assembly 302, and the extrusion of the clamping hand assembly 302 to the fence is reduced.

[0062] Further, as shown in Figures 6-9As shown, the sliding base 315 is provided with a through slot, the fixing base 316 is arranged in the through slot, the fixing base 316 is provided with a second linear guide rail pair 317 between the side faces close to the through slot, for example, the inner side wall of the through slot is provided with the slider of the second linear guide rail pair 317, and the side face of the sliding base 315 is provided with the linear guide rail of the second linear guide rail pair 317, so that the connection of the sliding base 315 and the fixing base 316 is realized through the second linear guide rail pair 317.

[0063] The bottom face of the fixing base 316 is opened, the fixing shaft 320 and the moving piece 319 are arranged in the fixing base 316, the fixing shaft 320 is parallel to the second linear guide rail pair 317 outside, the buffer spring 318 is sleeved on the fixing shaft 320, the fixing shaft 320 penetrates through the moving piece 319, the buffer spring 318 is between the moving piece 319 and the inner wall of the fixing base 316, and the moving piece 319 is fixedly connected with the sliding base 315.

[0064] In the process of clamping the surrounding plate, theoretically, the clamping hand assembly 302 is just in contact with the surrounding plate, and the surrounding plate and the clamping hand assembly 302 will not be subjected to extrusion force, but in actual production, due to the deviation of the position of the surrounding plate, the surrounding plate is often subjected to extrusion of the clamping hand assembly 302, and the clamping hand assembly 302 will also be subjected to a reaction force, so that the part of the clamping hand 308 of the clamping hand assembly 302 is loose, which is not conducive to production. Further, the utility model also improves the clamping hand assembly 302, specifically, the clamping hand assembly 302 comprises a clamping cylinder 306, a clamping hand 308, a connecting piece 310, a connecting shaft 311, a connecting rod 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 with the connecting piece 310, the two connecting shafts 311 are symmetrically arranged on the two sides of the connecting piece 310, the connecting shaft 311 penetrates through the mounting frame 307, and one end of the connecting shaft 311 is provided with a limiting portion, and the other end of the connecting shaft 311 is provided with two self-locking nuts 321, there is a gap between the self-locking nut 321 and the mounting frame 307, one end of the clamping hand 308 is in the mounting frame 307 and the connecting shaft 311 penetrates through the clamping hand 308, one end of the connecting rod 309 is hinged with the clamping hand 308, and the other end of the connecting rod 309 is hinged with the connecting piece 310. The clamping cylinder 306 is connected with the gas storage tank 304.

[0065] Due to the 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 hand 308 abuts against the connecting shaft 311 during rotation, the connecting shaft 311 can follow the rotation and the limiting nut will not be loose due to external force.

[0066] It is easy to understand that the circumferential side face of one end of the connecting shaft 311 provided with the self-locking nut 321 is a threaded face, so as to be connected with the self-locking nut 321, and the utility model will not be described here.

[0067] Further, as shown in Figure 9 The wear-resistant sleeve 312 penetrates the clamping hand piece 308, the wear-resistant sleeve 312 is in interference fit with the clamping hand piece 308, two positioning sleeves 313 are arranged at two ends of the wear-resistant sleeve 312 respectively, the positioning sleeve 313 is between the end of the wear-resistant sleeve 312 and the inner wall of the adjacent mounting frame 307, the connecting shaft 311 penetrates the wear-resistant sleeve 312 and the two positioning sleeves 313, and the connecting shaft 311 is in clearance connection with the wear-resistant sleeve 312 and the positioning sleeve 313. The clamping hand piece 308 is in direct contact with the wear-resistant sleeve 312, and when the clamping hand piece 308 rotates, the wear-resistant sleeve 312 and the connecting shaft 311 actually rotate relatively, and the two positioning sleeves 313 limit the clamping hand piece 308, so that the clamping hand piece 308 does not deviate too much along the axial direction of the connecting shaft 311.

[0068] In addition, the positioning sleeve 313 also helps to prevent the clamping hand piece 308 from loosening, and the reason is that when the clamping hand piece 308 is affected by external force and tends to abut against the connecting shaft 311, the wear-resistant sleeve 312 is limited by the positioning member, that is, the wear-resistant sleeve 312 applies a force to the positioning sleeve 313 on one side, so that the positioning sleeve 313 is pressed against the inner wall of the adjacent mounting frame 307, and therefore the wear-resistant sleeve 312 transfers the force originally affecting the connecting shaft 311 to the adjacent positioning sleeve 313, at this time the clamping hand piece 308 can still rotate, but the resistance is larger, 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 loosening of the connecting shaft 311.

[0069] Preferably, a gasket 314 is arranged between the limiting portion of the connecting shaft 311 and the mounting frame 307.

[0070] Preferably, a gasket 314 is arranged between the limiting portion of the connecting shaft 311 and the mounting frame 307.

[0071] The utility model also proposes the method of lower coaming, realizes through above-mentioned lower coaming machine, specific as follows:

[0072] S1, the lifting mechanism in the steel belt lifting buffer device 2 controls the lower machine frame 202 to descend through the release of the steel belt 209, in the descending process, the multiple clamping hand mechanisms of the coaming clamping device 3 stretch out outward, avoid the coaming below;

[0073] If the coaming clamping device 3 abuts against the top surface of the coaming, the coaming supports the coaming clamping device 3, so that the steel belt 209 is in a gradually relaxed state, avoiding the lower machine frame 202 from continuing to press down and causing the coaming to be damaged, 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 reduction of the output torque reaches the prewarning value, the lifting mechanism stops and sends out an alarm.

[0074] If the clamping plate device 3 is always not in contact with the top surface of the surrounding plate or the output torque detected by the lifting motor 203 always fails to reach the pre-warning value, step S2 is entered;

[0075] S2, after the lower rack 202 is lowered into position, the plurality of clamping hand mechanisms of the clamping plate device 3 are retracted, so that the clamping hand assemblies 302 are in contact with the rib plates of the outer side surface of the surrounding plate;

[0076] During the retraction of the clamping hand mechanisms, the buffer assembly between the clamping hand assemblies 302 and the mounting rods 301 provides a certain movement distance for the clamping hand assemblies 302, so as to reduce the large extrusion force of the clamping hand assemblies 302 on the surrounding plate from the outer side surface of the surrounding plate;

[0078] S4, the lifting mechanism controls the upper rack 202 to rise, so that all the surrounding plates are separated from the finished plate and leave the production line.

The principle and implementation mode of the utility model are described by applying specific examples in this paper, and the above embodiment description is only used to help understand the core idea of the utility model. It should be pointed out that for ordinary skilled persons in the technical field, some improvements and modifications can be made to the utility model without departing from the principle of the utility model, and these improvements and modifications also fall within the protection scope of the utility model claims.
