Description

Technical Field

[0001] This application relates to the field of tile presses, and more particularly to a pressing device for tile production. Background Technology

[0002] A roof tile press is a machine used to manufacture profiled roof tiles. Roof tile presses are widely used in the construction industry to produce decorative materials for roofs, walls, and other building surfaces.

[0003] Chinese utility model application CN200620086807.2 discloses a hydraulic tile press, including a base, a vertical arm, a machine head, an upper die, a lower die, and a power device for driving the upper die downward. The power device includes a hydraulic pump, an electric motor driving the hydraulic pump, and a hydraulic cylinder driven by the hydraulic pump. The piston rod of the hydraulic cylinder is fixedly connected to the upper die. The hydraulic pipeline is also equipped with an overflow valve and a manual directional valve. A filling valve is also installed on the oil inlet pipeline of the rodless chamber of the hydraulic cylinder. This utility model replaces the mechanical transmission of ordinary tile presses with hydraulic transmission. During the production process, the user can adjust the oil pressure according to the production needs. Compared with products produced by ordinary tile presses, the produced tiles are more uniformly stressed, have higher forming density, and higher strength.

[0004] After the workers put the clay into the lower mold, the upper and lower molds press the tile blanks together. After pressing, the workers remove the tiles. However, manually removing the tiles is inefficient. Summary of the Invention

[0005] To improve the efficiency of pressing tiles, this application provides a pressing device for tile production.

[0006] This application provides a pressing device for tile production, which adopts the following technical solution:

[0007] A pressing device for tile production includes a frame with a conveyor belt. An upper die is positioned above the conveyor belt, and a lifting member is connected to the top of the upper die. Multiple processing holes are evenly spaced along the length of the conveyor belt on its surface. A lower die is positioned within each processing hole and is detachably connected to the inner wall of the processing hole. A feeding belt is positioned on the side of the conveyor belt away from the upper die, and a connecting member is positioned on its surface. The lifting member is used to push the lower die out of the processing hole through the upper die and connect the lower die to the connecting member.

[0008] By adopting the above technical solution, the worker places the clay material in the lower mold, and the conveyor belt transports the lower mold to directly below the upper mold. The lifting component drives the upper mold to descend, pushing the lower mold out of the processing hole to the surface of the feeding belt and connecting it with the connector, thus completing the pressing of the clay material. After pressing the clay material into a tile, the lifting component drives the upper mold to rise, and the feeding belt can transport the lower mold and the tile. In this way, the tile can be separated from the processing hole when pressing the tile. The conveyor belt transports the next lower mold to directly below the upper mold, so that the next tile pressing can be carried out, which can improve the working efficiency of pressing tiles.

[0009] Preferably, a first support plate is provided on the side of the conveyor belt away from the upper mold. The length direction of the first support plate is consistent with the length direction of the conveyor belt. The first support plate has a through hole located above the feeding belt.

[0010] By adopting the above technical solution, after the conveyor belt transports the lower die to the top of the through hole, the lifting component drives the upper die to push the lower die out of the processing hole and through the through hole to the surface of the feeding belt. The first support plate can support the conveyor belt and can minimize the deformation of the conveyor belt when the upper die presses down on the lower die, thereby improving the efficiency of pushing the lower die out of the processing hole.

[0011] Preferably, a second support plate is provided on the side of the feeding belt away from the upper mold. The length direction of the second support plate is consistent with the length direction of the feeding belt. A sliding groove is provided on the top of the second support plate. The length direction of the sliding groove is consistent with the length direction of the second support plate. Limiting grooves are provided on both sides of the sliding groove along the width direction. The length direction of the limiting grooves is consistent with the length direction of the second support plate. The top middle part of the feeding belt is located in the sliding groove, and the two ends of the top of the feeding belt along the width direction are located in the limiting grooves.

[0012] By adopting the above technical solution, when the upper die presses the lower die onto the feeding belt, the second support plate can support the feeding belt, which can minimize the deformation of the feeding belt, thereby facilitating the connection between the lower die and the connecting piece. Through the sliding groove and the limiting groove, after the lower die and the connecting piece are separated, the lower die can be prevented from falling from both sides of the feeding belt width direction as much as possible.

[0013] Preferably, the lower mold includes a base and a module. The top of the base has a receiving groove, the module is located in the receiving groove, and a first spring is provided in the receiving groove. One end of the first spring is connected to the bottom wall of the receiving groove, and the other end of the first spring is connected to the bottom of the module. The module is slidably connected to the base along the depth direction of the receiving groove.

[0014] By adopting the above technical solution, the workers place the clay on top of the module. When the upper mold is pressed down, the clay and the module can be pressed into the receiving groove together. At this time, the first spring is compressed and shortened. After the upper mold rises, the first spring returns to its original position and can push the module upward, thereby pushing the tile out of the receiving groove, which makes it convenient for the workers to separate the tile from the module.

[0015] Preferably, the conveyor belt has a limiting strip on the side away from the upper mold. The limiting strip is distributed at both ends of the processing hole along the length of the conveyor belt. A second spring is connected to the side of the two limiting strips that are far apart from each other. One end of the second spring is connected to the limiting strip, and the other end of the second spring is connected to a fixing strip. The fixing strip is connected to the conveyor belt. Guide surfaces are provided at the top and bottom of the side of the two limiting strips that are close to each other. The limiting strip is slidably connected to the conveyor belt along the length of the conveyor belt.

[0016] By adopting the above technical solution, after the worker places the lower mold in the machining hole, the bottom of the base can be supported by the limiting strip. When the upper mold presses down, the base moves toward the feeding belt, and the limiting strips can be moved away from each other by the guide surface. After the lower mold is pressed to the feeding belt, the limiting strips are reset by the second spring. When the upper mold rises, the limiting strips can be moved away from each other by the guide surface, thereby resetting the upper mold.

[0017] Preferably, the conveyor belt has two guide strips on the side away from the upper mold. The length direction of the two guide strips is consistent with the length direction of the conveyor belt. The two guide strips are spaced apart along the width direction of the conveyor belt. The guide strips are made of flexible material and have guide grooves. The length direction of the guide grooves is consistent with the length direction of the guide strips. The two ends of the limiting strip are located in the guide grooves, and the limiting strips are slidably connected to the guide strips along the length direction of the guide grooves.

[0018] By adopting the above technical solution, the limiting bar can be limited by the guide groove when it moves, which can minimize the bending of the second spring caused by the limiting bar moving away from the conveyor belt. The guide groove can also guide the limiting bar, which can improve the stability of the limiting bar when it moves. At the same time, the guide groove can support the limiting bar, which can make the limiting bar better support the base.

[0019] Preferably, a first magnetic strip is embedded in the side wall of the base, and a second magnetic strip is embedded in the inner wall of the machining hole. When the first magnetic strip approaches the second magnetic strip, the first magnetic strip and the second magnetic strip are attracted to each other.

[0020] By adopting the above technical solution, when the bottom of the base is supported by the limiting strip, the first magnetic strip and the second magnetic strip are attracted to each other, which can reduce the supporting force required for the limiting strip to support the base, thereby reducing the burden on the limiting strip.

[0021] Preferably, there are multiple connectors, all of which are electromagnets. The connectors are evenly spaced along the length of the feed belt. The electromagnets are embedded in the surface of the feed belt and electrically connected to a controller. A detection element is provided at the bottom of the receiving groove. The detection element is electrically connected to the controller. The detection element is used to detect the distance from the bottom of the module to the bottom of the receiving groove and output a distance value. The controller is used to receive the distance value and compare it with a preset value. When the distance value is less than the preset value, the controller controls the electromagnet to be energized. When the distance value is greater than the preset value, the controller controls the electromagnet to be de-energized.

[0022] By adopting the above technical solution, when the worker places the clay on top of the module, the module descends under the weight of the clay, the first spring is compressed, the distance value detected by the detector is less than the preset value, the electromagnet is energized, and when the upper mold presses the lower mold onto the feeding belt to press the tile, the electromagnet can attract the first spring, thereby adsorbing the lower mold onto the surface of the feeding belt. When the worker takes out the pressed tile, the module rises, the distance value detected by the detector is greater than the preset value, the electromagnet is de-energized, thus making it easy to remove the lower mold from the feeding belt.

[0023] Preferably, the module is fitted with a sealing ring, which contacts the inner peripheral wall of the receiving groove. The bottom of the base is provided with a plurality of first air vents, and a second air vent is provided on one side of the base. Both the first air vents and the second air vents are connected to the receiving groove. A switch for opening and closing the second air vent is provided on one side of the base. The connector is made of a flexible layer, which is laid on the surface of the feeding belt.

[0024] By adopting the above technical solution, when the upper mold presses the lower mold onto the feeding belt to press the tiles, the module descends and the first spring is compressed, which can discharge some of the gas in the receiving groove from the second vent. After the switch closes the second vent, the air pressure in the receiving groove is relatively small. The bottom of the base can be adsorbed by the flexible layer through the first vent, so that the lower mold can be adsorbed onto the feeding belt, which can improve the stability of the feeding belt in conveying the lower mold.

[0025] Preferably, the switch includes a third spring and a plug, one end of the plug is located in the second vent hole, the other end of the plug is located outside the second vent hole, one end of the third spring is connected to the inner wall of the second vent hole, and the other end of the third spring is connected to the end of the plug located in the second vent hole.

[0026] By adopting the above technical solution, when the module descends to discharge the gas in the receiving tank, the gas can push the block out of the second vent. After some of the gas in the receiving tank is discharged, the third spring resets to pull back the block so that the block seals the second vent. This allows the second vent to be opened and closed. When it is necessary to remove the tile, the worker pulls the block to open the second vent. The first spring can push the module upward, which can push the tile out of the receiving tank, thus making it easy to remove the tile.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The worker places the clay material into the lower mold. The conveyor belt transports the lower mold to directly below the upper mold. The lifting device drives the upper mold to descend, pushing the lower mold out of the processing hole to the surface of the feeding belt and connecting it with the connector. At the same time, the clay material is pressed. After the clay material is pressed into a tile, the lifting device drives the upper mold to rise. The feeding belt can transport the lower mold and the tile. This allows the tile to be separated from the processing hole during the pressing of the tile. The conveyor belt transports the next lower mold to directly below the upper mold, so that the next tile pressing can be carried out, which can improve the working efficiency of pressing tiles.

[0029] 2. When the limit bar moves, it can be limited by the guide groove, which can minimize the limit bar moving away from the conveyor belt and causing the second spring to bend. The guide groove can also guide the limit bar, which can improve the stability of the limit bar when moving. At the same time, the guide groove can support the limit bar, so that the limit bar can better support the base.

[0030] 3. When the upper mold presses the lower mold onto the feeding belt to press the tile, the module descends and the first spring is compressed, which can discharge some of the gas in the receiving groove through the second vent. After the switch closes the second vent, the air pressure in the receiving groove is relatively small. The bottom of the base can be adsorbed by the flexible layer through the first vent, so that the lower mold can be adsorbed onto the feeding belt, which can improve the stability of the feeding belt in conveying the lower mold.

[0047] The present application will be further described in detail below with reference to all the accompanying drawings.

[0048] This application discloses a pressing device for tile production.

[0049] Example 1:

[0050] Reference Figure 1 and Figure 2The pressing device for tile production includes a frame 100, a conveyor belt 200, and a feeding belt 500. The frame 100 is connected to a lifting component 101, which is connected to an upper die 300. The conveyor belt 200 is equipped with a lower die 400. The conveyor belt 200 is used to transport the lower die 400 directly below the upper die 300. The lifting component 101 is used to lift the upper die 300, thereby pressing the lower die 400 onto the feeding belt 500 while simultaneously pressing the tile. The feeding belt 500 is used to transport the lower die 400 and the tile, which can improve the working efficiency of pressing tiles.

[0051] The lifting component 101 uses a hydraulic cylinder, which is vertically positioned with its piston rod facing the conveyor belt 200. The top of the upper mold 300 is connected to the piston rod of the hydraulic cylinder. Both the conveyor belt 200 and the feeding belt 500 are horizontally positioned, with the conveyor belt 200 located below the upper mold 300 and the feeding belt 500 located below the top of the conveyor belt 200. The length direction of the feeding belt 500 is perpendicular to the length direction of the conveyor belt 200. The conveyor belt 200 has multiple rectangular machining holes 201, which are evenly spaced along the length direction of the conveyor belt 200. The lower mold 400 is disposed in the machining hole 201. The lower mold 400 includes a base 401 and a module 402. The base 401 is cuboid in shape and has a receiving groove 403 on its top. The module 402 is located in the receiving groove 403. A first spring 404 and a detection element 406 are disposed in the receiving groove 403. The first spring 404 is made of iron and one end is connected to the bottom of the module 402. The other end of the first spring 404 is connected to the bottom wall of the receiving groove 403. The detection element 406 is embedded in the bottom wall of the receiving groove 403. The detection element 406 is an ultrasonic ranging sensor and is electrically connected to a controller, which is an S7-200 PLC. The bottom of the base 401 has multiple first vent holes 408, which communicate with the receiving groove 403. In other embodiments, there may be only one first vent hole 408. First magnetic strips 405 are embedded on both outer walls of the base 401, and the length direction of the first magnetic strips 405 is distributed horizontally.

[0052] Reference Figure 3 and Figure 4Multiple limiting strips 204 are provided on the inner side of the conveyor belt 200, with one limiting strip 204 distributed on each side of the processing hole 201 along the length direction of the conveyor belt 200. The length direction of the limiting strip 204 is consistent with the width direction of the conveyor belt 200. Guide surfaces 207 are provided at the top and bottom of the two limiting strips 204 located on both sides of the same processing hole 201 facing each other. A second spring 205 is connected to the side of the two limiting strips 204 that are far apart from each other. The length direction of the second spring 205 is consistent with the length direction of the conveyor belt 200. Two guide strips 208, made of rubber, are provided on the inner side of the conveyor belt 200. The guide strips 208 are spaced apart along the width of the conveyor belt 200, with guide grooves 209 on opposite sides of each guide strip 208. The length of the guide grooves 209 is aligned with the length of the guide strips 208. A limiting strip 204 is located in each of the two guide grooves 209 along its length, and is slidably connected to the guide strips 208 along the length of the guide grooves 209. A fixing strip 206 is connected to the end of the second spring 205 away from the limiting strip 204. The fixing strip 206 is aligned with the width of the conveyor belt 200 and is fixedly connected to the conveyor belt 200.

[0053] A first support plate 202 is provided below the top of the conveyor belt 200. The length direction of the first support plate 202 is consistent with the length direction of the conveyor belt 200. A through hole 203 is provided in the middle of the first support plate 202. The through hole 203 is located directly below the upper mold 300. A limiting strip 204 is located between the first support plate 202 and the conveyor belt 200.

[0054] Reference Figure 4 and Figure 5 A second magnetic strip 210 is embedded in the inner wall of the machining hole 201 along the length direction of the conveyor belt 200, and the length direction of the second magnetic strip 210 is consistent with the width direction of the conveyor belt 200. When the base 401 is placed in the machining hole 201, the first magnetic strip 405 and the second magnetic strip 210 are attracted to each other, and the bottom of the base 401 rests on the guide surface 207 at the top of the limiting strip 204.

[0055] Reference Figure 1 and Figure 6Multiple connectors 501 are provided on the surface of the feeding belt 500. These connectors 501 are evenly spaced along the length of the feeding belt 500 and are electromagnets embedded in its surface. The electromagnets are electrically connected to a controller, which controls their energization. A detection element 406 detects the distance between the module 402 and the bottom wall of the receiving tank 403 and outputs the distance value. The controller receives this distance value and compares it with a preset value. When the worker places mud on top of the module 402, the module 402 descends due to the weight of the mud. If the distance value is less than the preset value, the controller energizes the electromagnet. When the upper mold 300 presses the lower mold 400 onto the surface of the feeding belt 500, the electromagnet attracts the first spring 404. When the worker removes the tile from the top of the module 402, the module 402 returns to its original position due to the first spring 404. If the distance value is greater than the preset value, the controller de-energizes the electromagnet.

[0056] A second support plate 502 is provided below the top of the feeding belt 500, and the length direction of the second support plate 502 is consistent with the length direction of the feeding belt 500. A sliding groove 503 is formed on the top of the second support plate 502. Limiting grooves 504 are formed on both inner sidewalls of the sliding groove 503 along the width direction of the feeding belt 500. The length directions of the sliding groove 503 and the limiting grooves 504 are consistent with the length direction of the second support plate 502. The middle part of the top of the feeding belt 500 is located in the sliding groove 503, and the two ends of the top of the feeding belt 500 along the width direction are respectively located in the two limiting grooves 504.

[0057] The implementation principle of Example 1 is as follows: The worker places the lower mold 400 in the processing hole 201 and places the clay material on top of the module 402. The conveyor belt 200 transports the lower mold 400 to directly below the upper mold 300. The lifting component 101 drives the upper mold 300 to press down the lower mold 400. The lower mold 400 passes through the processing hole 201 and the through hole 203 in sequence. The upper mold 300 presses the lower mold 400 onto the feeding belt 500. At the same time, the upper mold 300 and the lower mold 400 press the clay material into a tile. The electromagnet attracts the first spring 404, which can attract the lower mold 400 onto the feeding belt 500. The feeding belt 500 transports the lower mold 400. After the worker removes the tile from the module 402, the lower mold 400 can be placed back into the processing hole 201. After the upper mold 300 presses the lower mold 400 onto the feeding belt 500, the lifting component 101 drives the upper mold 300 to rise, and the conveyor belt 200 transports the next lower mold 400 directly below the upper mold 300, so that the next tile pressing can be carried out, which can improve the working efficiency of pressing tiles.

[0058] Example 2: The difference between it and Example 1 is that the lower mold 400 and the connecting piece 501 are different.

[0059] Reference Figure 7 and Figure 8The pressing device for tile production includes a feeding belt 500 and a lower die 400. The feeding belt 500 is provided with a connector 501. The connector 501 is made of a flexible layer. In this embodiment, the flexible layer is made of rubber and is laid on the surface of the feeding belt 500.

[0060] The lower mold 400 includes a base 401 and a module 402. The top of the base 401 has a receiving groove 403. The module 402 is fitted with a sealing ring 407, which contacts the inner wall of the receiving groove 403 and slides vertically against the inner wall of the receiving groove 403. The bottom of both sides of the base 401 has second vent holes 409, which communicate with the receiving groove 403.

[0061] Reference Figure 8 and Figure 9 A switch element 600 is provided on the outer side of the base 401. The switch element 600 includes a third spring 601 and a block 602. The third spring 601 is located in the second vent 409, and one end of the third spring 601 is connected to the inner wall of the second vent 409. The block 602 is frustoconical in shape. The smaller end of the block 602 is located in the second vent 409 and connected to the other end of the third spring 601, while the larger end of the block 602 is located outside the second vent 409.

[0062] The implementation principle of Example 2 is as follows: After the conveyor belt 200 transports the lower mold 400 to directly below the upper mold 300, the lifting component 101 drives the upper mold 300 to press the lower mold 400 down to the feeding belt 500. When the upper mold 300 is pressed down, the module 402 descends, and some of the gas in the receiving groove 403 is discharged from the second vent 409. The base 401 is adsorbed onto the flexible layer through the first vent 408. The worker pulls the block 602 to open the second vent 409, and the gas enters the receiving groove 403. The first spring 404 can lift the module 402, thereby lifting the tile and making it convenient for the worker to remove the tile from the module 402.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
