Description

TECHNICAL FIELD

[0001] The application relates to the technical field of ceramic tile production, in particular to a conveying device for ceramic tiles. BACKGROUND

[0002] As a basic material in the field of building decoration, ceramic tiles need to go through multiple core processes such as raw material preparation, pressing forming, high-temperature firing, surface polishing and quality detection in the production process. Since ceramic tiles are brittle after forming, and the production process is usually in a continuous assembly line mode, the running stability of the conveying device, which is the key equipment connecting each production process, directly affects the production efficiency and the qualified rate of finished products. In actual production, the conveying device needs to realize stable transfer, accurate positioning and orderly connection of the tiles to meet the strict requirements of subsequent polishing, sorting and other processes on the posture of the tiles.

[0003] At present, since the belt conveyor has the advantages of flat conveying surface and little damage to the surface of the tiles, after the production of the tile blanks is completed, the belt conveyor is usually used to convey and process the tile blanks. The existing belt conveying device is usually composed of a driving motor, a driving drum, a driven drum and a conveying belt. The driving motor drives the driving drum to rotate, thereby driving the conveying belt to move in a cycle, realizing the continuous conveying of the tiles. However, when the existing conveying equipment is used, the stacked tile blanks usually need to be manually placed on the conveying belt.

[0004] In addition, some conveying equipment also has a conveying belt for feeding arranged at the feeding end of the conveying belt, so that the vertically placed tile blanks can be directly poured on the inclined conveying belt, facilitating the feeding and conveying of the tile blanks and reducing the labor cost. Referring to the Chinese patent document with the publication number CN110980118A and the name of a building ceramic tile production device, the document comprises a feeding part and a conveying part arranged on a track. The feeding part is located above one side of the conveying part. The ceramic tiles conveyed by the feeding part fall on the conveying part and are continuously conveyed to the automatic stacking part by the conveying part. The conveying part comprises a plurality of conveying rollers arranged on a rack, and a conveying belt is wound around the plurality of conveying rollers. The ceramic tiles conveyed to the inclined side bottom end of the conveying belt fall on the material taking part by the pushing assembly. This scheme can automatically send the produced ceramic tiles to the material taking part, thereby reducing the labor cost and improving the production efficiency.

[0005] With reference to the technical scheme, although the tile taking and placing convenience can be optimized, there are still technical defects to be solved in actual application: when the tiles are conveyed to the transition position of the inclined conveying belt and the horizontal conveying belt, the center line of the stacked tiles crosses the center line of the transition section, and one end of the tile along the conveying direction will fall under the action of gravity due to the loss of support, resulting in hard collision between the tile and the conveying belt surface; and since the tiles are in a stacked state, the impact force generated by the falling will further cause collision between adjacent tiles, which is easy to cause tile breakage, seriously affecting the quality of the tile finished product. In view of the above transition section collision problem, the existing technology usually extends the transmission distance of the inclined section as much as possible under the premise that the conveying height remains unchanged, so as to slow down the slope of the inclined conveying section, so as to reduce the influence of the height difference on the stability of the tile conveying. However, this coping method, on the one hand, prolongs the overall land occupation space of the equipment, which puts forward higher requirements for the production workshop layout; on the other hand, the long-distance conveying belt has very high requirements for the flatness precision during installation, which not only increases the installation difficulty and cost, but also easily causes the conveying belt to deviate due to installation error, further affecting the conveying stability. SUMMARY

[0006] Therefore, the application provides a ceramic tile conveying device to solve the problem of tile breakage caused by collision due to the angle of the conveying belt during the conveying process of the ceramic tile.

[0011] By adopting the above technical scheme, the cross beam arranged movably can play different supporting roles in different scenes, when the ceramic floor tiles are loaded, the second roller frames are separated from the conveying belts on the same side of the second belt conveyor, at this time, the second belt conveyor can play a role of buffering the loading of the ceramic floor tiles, and the impact during the loading of the ceramic floor tiles is greatly reduced; when the ceramic floor tiles are conveyed, the second roller frames can play a role of hard support for the second belt conveyor, and the stable conveying of the ceramic floor tiles is ensured.

[0012] Optionally, springs are sleeved at the bottoms of the T-shaped rods, and the upper ends of the springs are abutted against the cross beam.

[0015] By adopting the above technical scheme, the pneumatic cylinder can drive the support rod to displace, and under the guidance and limiting action of the connecting rod, the support rod can always maintain a parallel posture with the second roller frame, thereby facilitating flexible switching of the support state of the cross beam and the upper end structure thereof on the conveying belt, and adapting to different operation requirements.

[0016] Optionally, the right end of the second belt conveyor is rotationally connected with a feeding support, the right end of the support rod is articulated with the middle part of the feeding support, and the connecting rod is arranged in parallel with the left side of the feeding support.

[0026] 1、Ceramic tile with the upper support bracket rotates to the second belt conveyor abuts, the damping effect of hydraulic damper and the spring on the T-shaped rod cooperate, which can effectively absorb the impact of the gravity of ceramic tile on the conveyor belt, avoid the rigid collision of ceramic tile and the conveyor belt, and when the adjusting frame rotates, the deformation of the conveyor belt drives the displacement of the adjusting roller, and then pushes the lever to rotate and compresses the hydraulic damper. The reverse damping force generated by the hydraulic damper can effectively slow down the inclination speed of the adjusting frame, preventing the ceramic tile from falling due to the rapid inclination of the adjusting frame; further reducing the breakage probability of the ceramic tile during the transition of the conveyor, improving the safety and qualification rate of the ceramic tile conveying process, and effectively reducing the probability of collision during the transition of the ceramic tile.

[0027] 2、The initial state of the adjusting frame is consistent with the inclination angle of the second belt conveyor, which can ensure the stable bearing of the ceramic tile before transition. When the center of gravity of the ceramic tile passes the shaft center of the connection between the two belt conveyors, the adjusting frame can gradually incline to the horizontal with the pressure difference around the hinge point, and simultaneously drive the conveyor belt to adaptively deform through the groove plate and the roller, so that the conveyor belt always adheres to the bottom surface of the ceramic tile, avoiding the shaking and falling of the ceramic tile during the transition process, realizing seamless and stable transition from the second belt conveyor to the first belt conveyor, and improving the continuity of the overall conveying process.

[0028] 3、When the cylinder drives the support rod to reset, the spring force can promote the support rod to tightly abut the cross beam, driving the second roller frame to reset upward along the T-shaped rod and forming a rigid support; and the precise abutment of the limiting shaft outside the groove plate and the limiting rod outside the second roller frame can ensure the alignment of the second roller frame and the groove plate, so that the conveyor belt always maintains a flat state, avoiding the deviation and dumping of the ceramic tile due to the deformation of the conveyor belt, providing a stable bearing basis for subsequent continuous conveying of the ceramic tile, and reducing the conveying failure.

DETAILED DESCRIPTION

[0037] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the following will combine the embodiments of the present application with the drawings for Figures 1-7 , a clear and complete description of the technical scheme of the embodiments of the present application is given. Based on the described embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0038] With reference to Figure 1 and Figure 7 , the present embodiment provides a ceramic tile conveying device, which comprises a first belt conveyor 1, a second belt conveyor 2, a transition mechanism, a damping mechanism 4 and a feeding mechanism. The first belt conveyor 1 is horizontally arranged and used for horizontally conveying ceramic tiles. The second belt conveyor 2 is arranged on the right side of the first belt conveyor 1 and is obliquely arranged to facilitate the feeding of ceramic tiles. The first belt conveyor 1 and the second belt conveyor 2 share one driving motor. Through the operation of the driving motor, the first belt conveyor 1 and the second belt conveyor 2 can be driven to work synchronously to convey ceramic tiles.

[0039] With reference to Figure 2 , Figure 4 and Figure 5, the transition mechanism comprises an adjusting frame 3, support rollers 31, groove plates 32 and rollers 321; the adjusting frame 3 is rotationally connected to a drive shaft at the joint of the first belt conveyor 1 and the second belt conveyor 2, the ends of the support rollers 31 are each rotationally connected to a corresponding mounting hole on the left side of the adjusting frame 3 through a one-way bearing 311, the support rollers 31 are arranged in a linear array, rubber sleeves 312 are fixedly sleeved on the outer sides of the support rollers 31, the rubber sleeves 312 can increase the friction between the support rollers 31 and the ceramic tiles, meanwhile, the one-way bearings 311 can prevent the support rollers 31 from rotating in the reverse direction, thereby greatly reducing the probability of the ceramic tiles sliding to the right when being transferred; the groove plates 32 are arranged on the right side of the adjusting frame 3, the rollers 321 are rotationally connected to the inner sides of the two groove plates 32 at equal intervals, and the rollers 321 are in abutment with the inner walls of the conveying belts inside the second belt conveyor 2.

[0040] With reference to Figure 2 and Figure 5 , the damping mechanism 4 comprises a lever 41 and a hydraulic damper 42; the lever 41 and the hydraulic damper 42 are each hingedly connected inside the second belt conveyor 2, the lever 41 and the hydraulic damper 42 are arranged in a V shape, the lower ends of the lever 41 and the hydraulic damper 42 are rotationally connected to an adjusting roller 43, and the adjusting roller 43 is in driving connection with the conveying belts inside the second belt conveyor 2.

[0041] During the conveying of the ceramic tiles at the transition position of the first belt conveyor 1 and the second belt conveyor 2, the initial state of the adjusting frame 3 is consistent with the inclination angle of the second belt conveyor 2, when the stacked ceramic tiles are conveyed to the transition position by the second belt conveyor 2, the ceramic tiles first contact the support rollers 31 on the left side of the adjusting frame 3; as the ceramic tiles continue to be conveyed, the center of gravity of the ceramic tiles gradually passes the shaft center at the joint of the first belt conveyor 1 and the second belt conveyor 2, at this time, the pressure of the ceramic tiles on the left side of the adjusting frame 3 gradually increases, under the driving of the pressure, the adjusting frame 3 gradually tilts to the left around its rotation point, until it is rotated to a state completely horizontal to the first belt conveyor 1, so as to realize the smooth receiving and transition of the ceramic tiles from the second belt conveyor 2 to the first belt conveyor 1.

[0042] During the process that the adjusting frame 3 begins to rotate to the left, the groove plates 32 on the right side of the adjusting frame 3 synchronously rotate with the adjusting frame 3, the rollers 321 inside the groove plates 32 come into contact with the surfaces of the conveying belts inside the second belt conveyor 2 and produce a pushing action, the pushing action causes the conveying belts inside the second belt conveyor 2 to adaptively deform (with reference to Figure 6), the deformation process always follows the displacement trajectory of the tile bottom surface, ensuring that the conveyor belt is in full contact with the tile bottom surface throughout the process, avoiding the suspension or shaking of the tile due to the discontinuity of the bottom support, thereby maintaining the position stability during the tile conveying process, and preventing the upper tile from sliding due to unstable support of the lower tile; at the same time of the deformation of the conveyor belt inside the second belt conveyor 2, the adjusting roller 43 is displaced, causing the lever 41 and the hydraulic damper 42 to rotate, and the hydraulic damper 42 is compressed, which can provide damping force to the deformation of the conveyor belt inside the second belt conveyor 2, thereby making the rotation of the adjusting frame 3 have a certain damping force, which can effectively avoid the phenomenon that the ceramic tile rapidly falls on one side due to unbalanced gravity when the ceramic tile transitions from the second belt conveyor 2 to the first belt conveyor 1, thereby greatly reducing the probability of breaking of the ceramic tile during conveying.

[0043] With reference to Figure 2 , Figure 3 and Figure 5 , the feeding mechanism includes a feeding support 9, a connecting rod 6, a support rod 7, a cylinder 8, and a support assembly 5; the feeding support 9 is rotationally connected to the inner right end of the second belt conveyor 2, the connecting rod 6 is hingedly connected to the inside of the second belt conveyor 2, the left end of the support rod 7 is hingedly connected to the end of the connecting rod 6, the cylinder 8 is hingedly connected to the inside of the second belt conveyor 2, the telescopic end of the cylinder 8 is hingedly connected to the middle of the support rod 7, the right end of the support rod 7 is hingedly connected to the middle of the feeding support 9, the connecting rod 6 is arranged in parallel with the left side of the feeding support 9, the distance between the upper and lower hinging points of the connecting rod 6 is equal to the distance between the upper and lower hinging points of the feeding support 9, the connecting line between the two hinging points of the connecting rod 6 and the two hinging points of the feeding support 9 can form a parallelogram, and the support assembly 5 is arranged inside the second belt conveyor 2 and is used for supporting the conveyor belt inside the second belt conveyor 2.

[0044] With reference to Figure 2 and Figure 5 , the support assembly 5 includes a T-shaped rod 51, a cross beam 52, and a second roller frame 53, the T-shaped rod 51 is arranged on the frame of the second belt conveyor 2, the front and rear ends of the cross beam 52 are respectively slidably connected to the corresponding T-shaped rod 51 on the same side, the left and right ends of the second roller frame 53 are respectively fixedly connected to the corresponding cross beam 52 on the same side, the two second roller frames 53 are respectively in abutment with the inner walls of the conveyor belts on the same side inside the second belt conveyor 2, the support rod 7 can be in abutment with the bottom surfaces of the two cross beams 52, and springs 511 are arranged on the bottoms of the T-shaped rods 51.

[0045] In the initial stage of ceramic tile conveying, the operator vertically stacks the ceramic tiles to be conveyed to the designated load-bearing area of the loading support 9, at this time the ceramic tiles are inclined to the left at a certain angle, ensuring that the stacked ceramic tiles are stable and fit the support bearing surface, then the cylinder 8 starts and outputs driving force to drive the support rod 7 to move, because the distance between the upper and lower hinge points of the connecting rod 6 is equal to the distance between the upper and lower hinge points of the loading support 9, the connecting line between the two hinge points of the connecting rod 6 and the two hinge points of the loading support 9 can form a parallelogram, as the cylinder 8 works, the support rod 7 can move downward, at the same time, the loading support 9 is smoothly rotated counterclockwise around its bottom hinge point, in this rotating process, the ceramic tiles stacked on the loading support 9 move synchronously with the loading support 9, finally the stacked ceramic tiles are transferred to the conveying area of the second belt conveyor 2, the stacked ceramic tiles are conveyed by the second belt conveyor 2, without manual carrying, the batch transfer of the tiles is completed, which not only reduces the labor intensity of the operator, but also avoids the possibility of tile bumping during manual transfer.

[0046] When the cylinder 8 drives the support rod 7 to move downward, under the guidance of the connecting rod 6 and the loading support 9, the support rod 7 moves downward to the left along an arc trajectory, so that the support rod 7 is separated from the cross beam 52, when the stacked ceramic tiles abut against the conveying belt of the second belt conveyor 2, the conveying belt of the second belt conveyor 2 can deform under the pressure of the ceramic tiles; so that the hydraulic damper 42 is compressed, the second roller shaft frame 53 and the cross beam 52 can slide downward along the T-shaped rod 51 by a certain distance, the spring 511 is compressed, and the hydraulic damper 42 can play a certain buffering and damping role in the loading of the ceramic tiles, thereby effectively avoiding the rigid contact between the ceramic tiles and the second belt conveyor 2, reducing the breakage of the corners of the ceramic tiles, the local excessive wear of the conveying belt and other problems, reducing the impact of the ceramic tiles on the second belt conveyor 2, prolonging the overall service life of the device, and reducing the rebound of the ceramic tiles during loading, ensuring that the tiles are stacked neatly during loading, and reducing the probability of misalignment during subsequent ceramic tile conveying. After the loading is completed, the ceramic tiles are conveyed a certain distance to the left on the second belt conveyor 2, then the cylinder 8 drives the support rod 7 to reset, and the spring 511 resets, so that the support rod 7 abuts against the cross beam 52 and resets the cross beam 52, at this time the cylinder 8 fixes the support rod 7, thereby making the second roller shaft frame 53 support the conveying belt of the second belt conveyor 2 rigidly, while keeping the second roller shaft frame 53 aligned with the recessed plate 32, keeping the internal conveying belt of the second belt conveyor 2 flat, making the conveying of the ceramic tiles more stable, and the support rod 7 drives the loading support 9 to reset, preparing for the loading of the subsequent batch of ceramic tiles, realizing the cyclic and continuous operation of the device, and effectively improving the overall efficiency of tile conveying.

[0047] Referring to Figure 2And Figure 4 The outer side of the groove plate 32 is provided with a limiting shaft 322, and the outer side of the second roller support 53 is provided with a limiting rod 531 capable of abutting against the limiting shaft 322.

[0048] When the ceramic tiles are conveyed on the second belt conveyor 2, the limiting shaft 322 on the outer side of the groove plate 32 abuts against the limiting rod 531 on the outer side of the second roller support 53, so that the second roller support 53 is kept aligned with the groove plate 32, and the flatness of the conveying belt inside the second belt conveyor 2 is maintained.

[0049] With reference to Figure 1 And Figure 2 The inner side of the first belt conveyor 1 is provided with a fixed rod 101 fixedly installed by bolts, and the two fixed rods 101 are directly provided with a first roller support 102, and the two second roller supports 53 abut against the inner walls of the conveying belts on the same side of the first belt conveyor 1, so as to stably support the conveying belts inside the first belt conveyor 1.

[0050] In use, the operator places the ceramic tiles vertically on the loading support 9, and then the cylinder 8 drives the supporting rod 7 to move downward and drives the loading support 9 to rotate counterclockwise, so that the ceramic tiles are transferred to the second belt conveyor 2; during the loading process, the hydraulic damper 42 and the spring 511 provide buffering to avoid rigid collision of the ceramic tiles with the second belt conveyor 2; after the loading is completed, the tiles are conveyed to the left with the conveyor, and the cylinder 8 drives the supporting rod 7 to reset; under the action of the spring 511, the supporting rod 7 abuts against the cross beam 52 again, and the cross beam 52 and the second roller support 53 are reset upward along the rod body. After resetting, the second roller support 53 forms a hard support for the second belt conveyor 2, the outer limiting shaft 322 abuts against the limiting rod 531, and the position alignment is ensured; the supporting rod 7 is reset synchronously to drive the loading support 9 to rotate clockwise; during the tile conveying, the adjusting frame 3 can automatically tilt according to the change of the center of gravity to realize smooth transition of the ceramic tiles to the first belt conveyor 1, and at the same time, the deformation of the conveying belt drives the adjusting roller 43 and the push rod 41 to act, the hydraulic damper 42 is compressed to provide damping for the rotation of the adjusting frame 3, the tilting speed is slowed down, the impact of the falling tiles is prevented, and the risk of breaking is reduced; the deformation of the conveying belt inside the second belt conveyor 2 can ensure that the conveying belt is in full contact with the bottom surface of the tiles, so as to avoid the tiles from being suspended or shaken due to intermittent support of the bottom surface, and thus the position stability during the tile conveying is maintained; automatic loading, buffering protection and stable conveying of the ceramic tiles are realized.

[0051] The implementation principle of the ceramic tile conveying device in the embodiment is as follows:

[0052] When loading, first stack the ceramic tiles vertically on the loading support 9, then start the cylinder 8, on the one hand drive the support rod 7 to move downward, on the other hand pull the loading support 9 to rotate counterclockwise around the hinge point, so that the stacked ceramic tiles on the loading support 9 are transferred to the upper end face of the second belt conveyor 2 synchronously, and finally realize the subsequent conveying of the stacked ceramic tiles through the second belt conveyor 2.

[0053] In this process, while the cylinder 8 drives the support rod 7 to move downward, under the guidance and constraint of the connecting rod 6, the support rod 7 always maintains a parallel posture with the second roller frame 53 and moves downward to the left side along an arc trajectory, thereby realizing the separation of the support rod 7 and the cross beam 52; when the stacked ceramic tiles are rotated with the loading support 9 to abut against the conveying belt of the second belt conveyor 2, the gravity of the ceramic tiles will generate pressure on the conveying belt, prompting the conveying belt to deform to a certain extent; at the same time, the hydraulic damper 42 associated with the conveying belt is compressed, the second roller frame 53 and the cross beam 52 can slide downward along the T-shaped rod 51 by a certain distance, and the spring 511 on the T-shaped rod 51 is also compressed synchronously; through the damping action of the hydraulic damper 42 and the elastic buffering action of the spring 511, buffering protection is provided for the loading process of the ceramic tiles, avoiding rigid collision between the tiles and the conveying belt.

[0054] After the loading action is completed, the ceramic tiles are conveyed a certain distance to the left with the second belt conveyor 2, at this time the cylinder 8 drives the support rod 7 to reset; under the elastic force of the spring 511, the support rod 7 re-abuts against the cross beam 52, and the cross beam 52 drives the second roller frame 53 to reset upward along the T-shaped rod 51. After resetting, the second roller frame 53 forms a hard support for the conveying belt of the second belt conveyor 2, the limiting shaft 322 outside the groove plate 32 abuts against the limiting rod 531 outside the second roller frame 53, ensuring that the second roller frame 53 is aligned with the groove plate 32, and ensuring that the conveying belt inside the second belt conveyor 2 always maintains a flat state, providing stable conditions for subsequent tile conveying; in addition, the support rod 7 drives the loading support 9 to rotate clockwise to reset during the resetting process, so as to perform the loading operation of the next batch of ceramic tiles.

[0055] When the stacked ceramic tiles are conveyed to the transition position of the first belt conveyor 1 and the second belt conveyor 2 with the second belt conveyor 2, the initial state of the adjusting frame 3 is consistent with the inclination angle of the second belt conveyor 2, ensuring stable loading of the tiles before transition.

[0056] With the ceramic tiles continue to be transported, when the center of gravity of the ceramic tiles passes the axis of the joint of the first belt conveyor 1 and the second belt conveyor 2, the pressure on the left side (close to the first belt conveyor 1) of the ceramic tiles gradually becomes greater than the pressure on the right side; under the action of the pressure difference, the adjusting frame 3 gradually tilts to the left around its own hinge point until the adjusting frame 3 rotates to a position where it is level with the first belt conveyor 1, at which time the ceramic tiles are smoothly transferred to the first belt conveyor 1, completing the stable transition from the second belt conveyor 2 to the first belt conveyor 1.

[0057] When the adjusting frame 3 begins to rotate to the left, the groove plate 32 connected to the right side of the adjusting frame 3 moves synchronously with the roller 321, which triggers adaptive deformation of the conveyor belt inside the second belt conveyor 2, so that the conveyor belt can always maintain contact with the bottom surface of the ceramic tiles, ensuring the stability of support during the conveying of the tiles.

[0058] At the same time, when the conveyor belt inside the second belt conveyor 2 deforms, it will cause the associated adjusting roller 43 to displace; during the displacement of the adjusting roller 43, the push rod 41 is pushed to rotate, which further causes the hydraulic damper 42 to rotate and be compressed; through the damping action of the hydraulic damper 42, a counter-damping force is provided for the rotation of the adjusting frame 3, effectively slowing down the tilting speed of the adjusting frame 3, avoiding the impact of the ceramic tiles due to the rapid tilting of the adjusting frame 3, and ultimately greatly reducing the probability of breakage of the ceramic tiles during the conveying process.

[0059] The above describes the preferred embodiments of the present application, and it should be noted that for those skilled in the art, without departing from the principles described in the present application, a number of improvements and refinements can be made, which should also be considered within the scope of protection of the present application.
