Description

Technical Field

[0001] The present application relates to the technical field of tile adhesive testing, and in particular to a test piece preparation device for testing the tensile bonding properties of tile adhesives. Background Art

[0002] In modern architectural decoration, ceramic tiles are widely used for flooring, walls, and exterior cladding due to their aesthetics, wear resistance, and ease of cleaning. The adhesive between the tiles and the substrate directly determines the quality and safety of the paving process and is a key factor in ensuring the long-term stability of a building.

[0003] Reference Figure 18 With the increasingly stringent standards in the construction industry, the country has put forward clear requirements for the tensile bond strength of tile adhesives. Therefore, professional personnel are required to conduct tensile bond strength tests on tile adhesives before construction. The tiles are 50*50mm in size. The following test process is usually adopted: First, the tile adhesive is thoroughly mixed and evenly mixed using a mixer specified in the standard. The staff manually scrapes the evenly mixed tile adhesive slurry onto the substrate plate 60 specified in the standard, so that the substrate plate 60 is coated with a mortar layer 70. A toothed knife is used to scrape multiple adhesive strips 80 on the mortar layer 70. Then, multiple standard-sized ceramic tiles 90 are manually pasted. The spacing between adjacent ceramic tiles is 40mm. The adhesive strips can be compressed to fill the gaps under the ceramic tiles, so that the ceramic tiles can be stably adhered to the mortar layer 70. Then, pressure blocks of the same weight are placed on the ceramic tiles one by one. Each pressure block presses the ceramic tile for the same time. Finally, the tiles are transferred to the curing room, processed according to the standard, and moved under the testing machine for tensile bond strength testing of the ceramic tile adhesive.

[0004] Reference Figure 18 Since the ceramic tile pieces 90 are placed and pasted on the mortar layer 70 manually, it is difficult to place them absolutely horizontally. Therefore, when the staff places the pressing blocks, the ceramic tile pieces 90 are very likely to slip and tilt. It is impossible to ensure that the force direction of each ceramic tile piece 90 is vertical during the strength test, resulting in a smaller tensile bond strength test result, which seriously affects the accuracy of the strength test results. There is room for improvement. Summary of the Invention

[0005] In order to ensure that the ceramic tile pieces can be placed horizontally on the mortar layer, the present application provides a test piece preparation device for testing the tensile bonding properties of ceramic tile adhesives.

[0006] This application provides a test specimen preparation device for testing the tensile bonding properties of tile adhesives, which adopts the following technical solutions: A device for preparing specimens for testing the tensile bonding properties of tile adhesives, comprising a frame, the frame being provided with a second bracket, a conveying mechanism for conveying a substrate plate, and a clamping mechanism for clamping and fixing the substrate plate, the clamping mechanism being provided on the conveying mechanism, the second bracket being provided with a horizontal placement plate and an adsorption and lowering structure for horizontally adsorbing a tile plate and vertically descending the tile plate, the horizontal placement plate being in sliding engagement with the second bracket; The horizontal placement plate is provided with a plurality of guide grooves for guiding the ceramic tiles to be accurately placed on the mortar layer of the base material plate; a left opening and closing plate and a right opening and closing plate are relatively slidingly arranged under any guide groove on the horizontal placement plate; an opening and closing drive structure for driving all the left opening and closing plates and the right opening and closing plates to open and close synchronously is arranged inside the horizontal placement plate; when the ceramic tiles are horizontally placed on the mortar layer of the base material plate, any of the left opening and closing plates and any of the right opening and closing plates respectively form an abutment fit with the upper surface of the ceramic tiles.

[0007] By adopting the above technical solution and utilizing the setting of the conveying mechanism and the clamping mechanism, the stable conveying and clamping fixation of the base material plate is realized. When the left opening and closing plate and the right opening and closing plate are in the closed state, and in conjunction with the setting of the guide groove on the horizontally placed plate, the staff places the ceramic tiles in the guide groove one by one, and the lower surface of the ceramic tiles abuts against the closed left opening and closing plate and the right opening and closing plate. The ceramic tiles are adsorbed and driven down by the adsorption and descending structure, ensuring that the ceramic tiles always remain in a horizontal state during the adsorption and descending process. When the left opening and closing plate and the right opening and closing plate are in the open state, the adsorption and descending structure drives the ceramic tiles It descends to the surface of the mortar layer and releases the adsorption force on the ceramic tile. At this time, the ceramic tile falls horizontally onto the mortar layer of the base plate; the left opening and closing plate and the right opening and closing plate are driven to close by the opening and closing drive structure, and the adsorption descending structure continues to descend and press the horizontally placed plate, so that all the left opening and closing plates and the right opening and closing plates on the horizontally placed plate are respectively pressed against the ceramic tile, ensuring that all ceramic tiles are subjected to uniform force and the force direction is vertical, effectively avoiding slippage and tilting of the ceramic tile, thereby greatly improving the accuracy of the test results of the tensile bonding strength performance of the ceramic tile adhesive, and providing reliable guarantee for the quality inspection of the ceramic tile adhesive.

[0008] Preferably, the adsorption and descending structure includes a lifting plate, a second electric cylinder fixed on the second bracket, a hollow cylinder arranged on the lifting plate and a suction nozzle for adsorbing ceramic tiles. The piston rod of the second electric cylinder is fixedly connected to the lifting plate, the position and number of the hollow cylinder correspond to the guide groove, and the suction nozzle corresponds to the position and number of the hollow cylinder. Any of the suction nozzles slides vertically on the hollow cylinder, and any of the suction nozzles is connected to an external vacuum pump through an air pipe.

[0009] By adopting the above technical solution, the suction nozzle is connected to the vacuum pump through the air pipe to provide stable adsorption force, and the hollow cylinder constrains the movement trajectory of the suction nozzle. By controlling the third electric cylinder to drive the lifting plate to drive the hollow cylinder and the suction nozzle to descend, it is ensured that the ceramic tile falls horizontally along the guide groove to the specified position of the substrate plate, realizing stable adsorption and precise placement of the ceramic tile, while avoiding position deviation caused by manual operation, further ensuring the horizontality and efficiency of ceramic tile placement, and helping to improve the reliability of the tensile bonding strength performance test of ceramic tile adhesives.

[0010] Preferably, the opening and closing drive structure includes a driving plate, a first connecting plate provided on the left opening and closing plate, a second connecting plate provided on the right opening and closing plate, a first linkage rod perpendicular to the first connecting plate, a second linkage rod perpendicular to the second connecting plate, and a slide rail provided on the horizontally placed plate, the driving plate is connected to the first linkage rod, any one of the first connecting plates is connected to the first linkage rod, any one of the second connecting plates is connected to the second linkage rod, any one of the left opening and closing plate and any one of the right opening and closing plates are slidably provided on the slide rail, and the second bracket is provided with a control mechanism for accurately controlling the left and right movement of the driving plate; A first rack is provided on the first linkage rod, and a second rack is provided on the second linkage rod. The first rack and the second rack are arranged in parallel. A transmission gear is provided between the first rack and the second rack, and the first rack and the second rack respectively form a meshing transmission with the transmission gear.

[0011] By adopting the above technical solution, in actual operation, the driving plate is controlled by the operation control mechanism to drive the first linkage rod to move. Since the first rack and the second rack respectively form an engaged transmission with the transmission gear, the first driving plate reversely drives the second linkage rod to move, thereby enabling multiple groups of first connecting plates and second connecting plates to open and close in the opposite direction, thereby enabling multiple groups of left opening and closing plates and right opening and closing plates to open and close synchronously. At the same time, the setting of the slide rail is used to ensure the smoothness of the opening and closing process. This design only requires operating the driving plate to drive the synchronous opening and closing actions of all left opening and closing plates and right opening and closing plates, thereby ensuring the consistency of the actions of multiple groups of opening and closing plates.

[0012] Preferably, the control mechanism includes a second fixed plate, a third connecting plate, a horizontally arranged connecting rod, a connecting spring for driving the third connecting plate to move left and right, two oppositely arranged guide plates, a fourth connecting plate for connecting the guide plate and the driving plate, two oppositely arranged pulleys and an N-shaped frame fixed to the lifting plate; The second fixing plate is fixed to the second bracket, one side of the two guide plates is connected to the third connecting plate, and the other side of the two guide plates is connected to the fourth connecting plate, the fourth connecting plate and the driving plate are fixed by bolts, the connecting spring is sleeved on the connecting rod, one end of the connecting rod is plug-fitted with the second fixing plate, and the other end is connected to the third connecting plate, one end of the connecting spring is connected to the second fixing plate, and the other end is connected to the third connecting plate; A connecting rod is provided on the end of the N-shaped frame away from the lifting plate, and the two ends of the connecting rod are respectively connected to the pulleys in a rotational manner. The opposite sides of the two guide plates are respectively provided with a sliding groove group for guiding the direction of the pulleys. A second spring is provided between any of the pulleys and the connecting rod, and any of the second springs is sleeved on the connecting rod.

[0013] By adopting the above technical solution, when the pulley moves down with the lifting plate, the pulley slides in the slide groove group. At the same time, the connecting spring is set, and the connecting spring is stretched or contracted according to the position of the pulley in the slide groove group, thereby driving the third connecting plate and the guide plate to move left and right, and the vertical movement of the lifting plate is converted into horizontal movement of the guide plate, and then the opening and closing timing of the left opening and closing plate and the right opening and closing plate is controlled by the driving plate to ensure the accuracy and stability of the placement of the ceramic tiles.

[0014] Preferably, the frame is provided with a first bracket, an adhesive stirring mechanism arranged on the first bracket, a glue discharge structure for controlling the glue discharge of the adhesive stirring mechanism, a scraping structure for scraping the glue layer on the substrate plate, and a toothed knife structure for scraping glue strips from the scraped glue layer, and the adhesive stirring mechanism is arranged above the glue discharge structure.

[0015] By adopting the above technical solution, the stirring mechanism on the first bracket is used to realize adhesive pre-processing, and the glue discharge situation of the mortar stirring mechanism is controlled by the glue discharge structure. After the scraping structure evenly applies the mortar layer, the toothed knife structure scrapes out a standard glue strip on the glue layer, thereby ensuring the smearing quality and uniformity of the mortar layer on the substrate board. This design integrates the functions of mortar stirring, glue discharge, scraping and toothed knife scraping strip into one, reducing the process error and time cost of preparing tile adhesive specimens and improving the standardization of test samples.

[0016] Preferably, the stirring mechanism includes a glue storage barrel fixed on the first bracket, a cover body rotatably connected to the top of the glue storage barrel, a stirring shaft rotatably connected to the inside of the glue storage barrel, stirring blades for stirring the adhesive and a third motor for driving the stirring shaft to rotate, a plurality of stirring blades are provided, and the stirring blades are arranged on the stirring shaft at cross intervals, the output shaft of the third motor is coaxially arranged with the stirring shaft, a glue outlet is opened at the bottom of the glue storage barrel, and the glue outlet structure forms an abutment fit with the glue outlet.

[0017] By adopting the above technical solution, during actual operation, the staff opens the cover to add materials into the glue storage cylinder, and drives the third motor to rotate the stirring shaft and the stirring blade, so that the various components of the tile adhesive in the glue storage cylinder can be stirred and mixed evenly, thereby ensuring the quality of the adhesive. At the same time, the glue outlet structure is used to control the closure of the glue outlet to ensure that the adhesive is taken in a quantitative manner as needed, thereby realizing controllable output of the adhesive and providing reliable quality adhesive for subsequent scraping and tile pasting.

[0018] Preferably, the glue discharge structure includes a mounting plate fixed to the bottom of the glue storage cylinder, connecting shafts formed on both sides of the mounting plate, a toggle plate rotatably connected to the connecting shaft, and a sealing plate for tightly sealing the glue outlet. The sealing plate is rotatably connected to the connecting shaft. A reset torsion spring is sleeved on any of the connecting shafts, one end of the reset torsion spring abuts against the toggle plate, and the other end abuts against the sealing plate. Limit blocks for limiting the rotation of the toggle plate are respectively extended on both sides of the sealing plate. A trapezoidal boss for driving the toggle plate to rotate is fixed on the clamping mechanism, and the trapezoidal boss forms an abutment fit with the toggle plate.

[0019] By adopting the above technical solution, when the substrate plate is transported into place by the clamping mechanism, the slope surface and upper surface of the trapezoidal boss are used to drive the toggle plate to rotate counterclockwise, and the toggle plate drives the sealing plate to rotate to open the glue outlet, so that the glue slurry can flow out and fall onto the substrate plate; after the glue is discharged, the trapezoidal boss is separated from the toggle plate, and the reset torsion spring resets the sealing plate, and the sealing plate is pressed against the glue outlet again to seal the glue outlet. This structural design realizes the automatic control of the glue discharge process, improves the working efficiency and operation convenience of the equipment, and ensures the accuracy and stability of the glue discharge amount.

The scrapers are provided with multiple specifications, any of which is provided on the rotating shaft, and the output shaft of the fourth motor is coaxially arranged with the rotating shaft.

[0021] By adopting the above technical solution and using the setting of multiple scrapers of different specifications, the scraping requirements of different adhesive layer thicknesses can be met. When in use, the fourth motor drives the rotating shaft to rotate, thereby driving the scraper of the required specifications to rotate to the appropriate height for scraping operations, providing a strong guarantee for accurately testing the tensile bonding strength of tile adhesives.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The stable conveying and clamping fixation of the substrate plate is achieved by utilizing the setting of the conveying mechanism and the clamping mechanism. When the left opening and closing plate and the right opening and closing plate are in the closed state, and in conjunction with the setting of the guide groove on the horizontally placed plate, the staff places the ceramic tiles in the guide groove one by one, and the lower surface of the ceramic tiles abuts against the closed left opening and closing plate and the right opening and closing plate. The ceramic tiles are adsorbed and driven down by the adsorption and descending structure to ensure that the ceramic tiles always remain in a horizontal state during the adsorption and descending process. When the left opening and closing plate and the right opening and closing plate are in the open state, the adsorption and descending structure drives the ceramic tiles down to The mortar layer is moved on the surface and the adsorption force on the tiles is released. At this time, the tiles fall horizontally onto the mortar layer of the substrate plate at the same time. The opening and closing drive structure then drives the left and right opening and closing plates to close. The adsorption descending structure continues to descend and press the horizontal placement plate, so that all the left and right opening and closing plates on the horizontal placement plate are respectively pressed against the tiles, ensuring that all the tiles are subjected to the same force and the force direction is vertical, effectively avoiding the tiles from slipping and tilting, thereby greatly improving the accuracy of the tensile bonding strength performance test results and providing reliable guarantee for the quality inspection of tile adhesives. 2. The suction nozzle is connected to a vacuum pump via an air pipe to provide stable suction force, while the hollow cylinder constrains the nozzle's movement trajectory. By controlling the third electric cylinder to drive the lifting plate, the hollow cylinder and the suction nozzle are lowered, ensuring that the tile falls horizontally along the guide groove to the specified position on the substrate plate. This achieves stable suction and precise placement of the tile, while avoiding position deviation caused by manual operation, further ensuring the levelness and efficiency of tile placement, and helping to improve the reliability of the tensile bond strength performance testing of tile adhesives. 3. The driving plate is controlled by operating the control mechanism to drive the first linkage rod to move. Since the first rack and the second rack are respectively engaged with the transmission gear, the first driving plate drives the second linkage rod to move in the reverse direction, thereby enabling multiple groups of first connecting plates and second connecting plates to open and close in the opposite direction, thereby enabling multiple groups of left opening and closing plates and right opening and closing plates to open and close synchronously. At the same time, the setting of the slide rail is used to ensure the smoothness of the opening and closing process. This design only requires operating the driving plate to drive the synchronous opening and closing of all left opening and closing plates and right opening and closing plates, thereby ensuring the consistency of the movements of multiple groups of opening and closing plates.

The mounting frames 81 are symmetrically arranged on both sides of the frame 1, and the rotating shaft 82 is rotatably connected between the two mounting frames 81. The scrapers 83 are provided with multiple specifications. In this embodiment, the scrapers 83 are provided with three of different heights. Any scraper 83 is fixed to the rotating shaft 82 by bolts. The fourth motor 84 is installed on one of the mounting frames 81, and the output shaft of the fourth motor 84 is coaxially arranged with the rotating shaft 82.

[0043] Reference Figure 5 In order to make the glue applied on the substrate plate 60 more stable, it is necessary to use a scraper 83 to repeatedly squeeze the glue, so as to control the thickness of each layer of glue layer by layer. At the same time, by stacking scrapers 83 of different heights layer by layer, the glue can more evenly fill the depressions or pores on the surface of the substrate plate 60, avoiding the situation where the glue layer 70 is locally too thick or too thin.

[0044] Reference Figure 2 and Figure 7 In actual operation, the staff drives the driving gear 451 to rotate by operating the first motor 41, and the driving gear 451 drives the driven gear 452 to rotate through the synchronous toothed belt 453. At this time, the sliding seat 44 fixed on the synchronous toothed belt 453 also transmits the conveyor frame 51 along the transmission direction, so that the conveyor frame 51 drives the trapezoidal boss 515 to move forward; Reference Figure 3 and Figure 5 When the conveying is in place, the fourth motor 84 is operated to select the scraper 83 with the highest height, and then the first electric cylinder 443 is operated to drive the connecting block 514 to drive the conveying frame 51 to extend forward; Reference Figure 6 and Figure 7 As the conveying frame 51 extends, the sloped surface on the front side of the trapezoidal boss 515 contacts the toggle plate 73 and applies a force to the toggle plate 73 along the conveying direction. At this time, due to the limiting effect of the limiting block 741, the toggle plate 73 drives the sealing plate 74 connected to the limiting block 741 to rotate counterclockwise. The toggle plate 73 drives the sealing plate 74 to rotate and open the glue outlet, allowing the adhesive to flow out and fall onto the substrate plate 60. Reference Figure 5 and Figure 7 As the conveyor frame 51 moves forward, the scraper 83 evenly and stably scrapes the adhesive layer 70 on the substrate plate 60. When the substrate plate 60 is completely covered with the adhesive layer 70, the piston rod of the first electric cylinder 443 extends to its full position, and the trapezoidal boss 515 is disengaged from the toggle plate 73. At this time, the sealing plate 74 is reset by the return torsion spring, and the first batch scraping operation is completed. Reference Figure 3 and 5 Then, the fourth motor 84 is operated to select the scraper 83 with a suitable height, and the first electric cylinder 443 is operated to drive the connecting block 514 to drive the conveying frame 51 to retract backward; Reference Figure 5 and Figure 8 As the conveyor frame 51 retracts, the scraper 83 can once again evenly and stably scrape the glue layer 70 on the substrate plate 60.

At this time, the toggle plate 73 will be forced to rotate clockwise, and the sealing plate 74 is always tightly against the glue outlet. When the piston rod of the first electric cylinder 443 retracts into place, the second batch scraping operation is completed.

The frame 1 is provided with a support unit 13 for supporting the horizontally placed plate 10. There are four support units 13, and the four support units 13 are symmetrically arranged in pairs along the length direction of the horizontally placed plate 10.

When the horizontal plates 10 are pressed down, the horizontal plates 10 drive the first fixed plates 132 to descend and compress the first springs 133. After the pressure is released, the first springs 133 can drive the first fixed plates 132 and the horizontal plates 10 to rise and reset.

The lifting plate 201 is provided with avoidance holes 2011 corresponding to the positions and numbers of the second guide columns 205. Any second guide column 205 is plug-fitted with the avoidance hole 2011 of the lifting plate 201, so that the second guide column 205 can guide the lifting plate 201 to descend horizontally and stably.

[0052] Reference Figure 12 and Figure 13 There are multiple hollow cylinders 203. In the present embodiment, there are ten hollow cylinders 203. The ten hollow cylinders 203 are divided into two rows and five columns of rectangles. Any hollow cylinder 203 is vertically fixed to the lifting plate 201 by bolts. A slide 2031 is symmetrically opened inside any hollow cylinder 203. The suction nozzles 204 are arranged corresponding to the position and number of the hollow cylinders 203. Any suction nozzle 204 slides vertically on the corresponding slide 2031 through a slider, and a step surface 2032 is provided at the bottom of the slide 2031 of the hollow cylinder 203. The step surface 2032 is used to limit the sliding of the suction nozzle 204 to prevent the suction nozzle 204 from falling during the sliding process.

The material of the suction nozzle 204 is set to rubber, and the head shape of the suction nozzle 204 is designed to be trumpet-shaped, which is used to better fit the surface of the tile piece 90 and improve the adsorption effect. When adsorbing the tile piece 90, the vacuum pump provides suction to the suction nozzle 204 through the air pipe 2041, so that the suction nozzle 204 can stably adsorb the tile piece 90.

[0054] Reference Figure 12 and Figure 14 The horizontally placed plate 10 is provided with a guide groove 101 and a supporting bottom frame 102. The supporting bottom frame 102 is surrounded on three sides to form an avoidance groove for avoiding the substrate plate 60. The horizontally placed plate 10 and the supporting bottom frame 102 are welded up and down, and a sandwich space is formed between the horizontally placed plate 10 and the supporting bottom frame 102. The guide groove 101 is used to guide the ceramic tile piece 90 to be accurately placed on the mortar layer 70 of the substrate plate 60. There are multiple guide grooves 101. In this embodiment, there are ten guide grooves 101 corresponding to the position and number of the suction nozzle 204. Any guide groove 101 is connected to the avoidance groove up and down.

The two left opening and closing plates 103 in the same column are arranged opposite to each other and are formed as one piece. The two right opening and closing plates 104 in the same column are arranged opposite to each other and are formed as one piece. When a group of left opening and closing plates 103 and right opening and closing plates 104 are in a closed state, a space is reserved between the left opening and closing plate 103 and the right opening and closing plate 104 for avoiding the suction nozzle 204.

[0056] Reference Figure 12 and Figure 13 In the initial state, any group of left opening and closing plates 103 and right opening and closing plates 104 are in a closed state. The staff now places ten ceramic tiles 90 in turn into the guide groove 101. At this time, any group of left opening and closing plates 103 and right opening and closing plates 104 provide horizontal support for the ceramic tiles 90, and then controls the second electric cylinder 202 to drive the lifting plate 201 to drive the hollow cylinder 203 and the suction nozzle 204 to descend, and the suction nozzle 204 adsorbs the ceramic tiles 90.

[0057] Reference Figure 12 and Figure 13 When the left opening and closing plate 103 and the right opening and closing plate 104 are driven to open, the suction nozzle 204 drives the tile piece 90 to fall accurately along the guide groove 101 to the specified position of the substrate plate 60, realizing stable adsorption and simultaneous precise placement of the tile piece 90, avoiding position deviation caused by manual operation, and ensuring the levelness and efficiency of the placement of the tile piece 90, which helps to improve the reliability of the tensile bonding strength test of the tile adhesive.

[0058] Reference Figure 12 and Figure 15 In order to drive all the left opening and closing plates 103 and the right opening and closing plates 104 to open and close synchronously, an opening and closing driving structure 30 is arranged in the interlayer space between the horizontally placed plate 10 and the supporting bottom frame 102. The opening and closing driving structure 30 includes a driving plate 301, a first connecting plate 302, a second connecting plate 303, a first linkage rod 304, a second linkage rod 305 and a slide rail 306. The first connecting plate 302 corresponds to the position and quantity of the left opening and closing plate 103, and the second connecting plate 303 corresponds to the position and quantity of the right opening and closing plate 104. The driving plate 301, the first linkage rod 304 and the second linkage rod 305 are all slidably set on the supporting bottom frame 102.

[0060] Reference Figure 14 Since the linkage modes between the two groups of first linkage rods 304 and second linkage rods 305 are the same, the linkage mode between one group of first linkage rods 304 and second linkage rods 305 is now described as an example.

[0061] Reference Figure 14 A first rack 307 is fixed to the first linkage rod 304 by bolts, and a second rack 308 is fixed to the second linkage rod 305 by bolts. The first rack 307 and the second rack 308 are arranged in parallel. A fixed shaft 1021 is vertically welded on the supporting bottom frame 102, and a transmission gear 309 is rotatably connected to the fixed shaft 1021. The transmission gear 309 is arranged between the first rack 307 and the second rack 308, and the first rack 307 and the second rack 308 respectively form a meshing transmission with the transmission gear 309.

[0062] When the operating driving plate 301 drives the first linkage rod 304 to move on the supporting bottom frame 102, since the first rack 307 and the second rack 308 respectively form an engaged transmission with the transmission gear 309, the first driving plate 301 reversely drives the second linkage rod 305 to move on the supporting bottom frame 102, thereby enabling multiple groups of first connecting plates 302 and second connecting plates 303 to open and close in the opposite direction, and then enabling multiple groups of left opening and closing plates 103 and right opening and closing plates 104 to open and close synchronously. This design only requires operating the driving plate 301 to drive the synchronous opening and closing actions of all left opening and closing plates 103 and right opening and closing plates 104, thereby ensuring the consistency of the actions of multiple groups of opening and closing plates.

[0063] Reference Figure 12 and Figure 14The slide rail 306 is fixed to the horizontally placed plate 10 by bolts, and an avoidance slide groove 105 for avoiding the slide rail 306 is provided between the two left opening and closing plates 103 in the same column and between the two right opening and closing plates 104 in the same column. Any left opening and closing plate 103 and any right opening and closing plate 104 can be slid onto the slide rail 306 through the avoidance slide groove 105, so that the left opening and closing plate 103 and the right opening and closing plate 104 are smoother during the opening and closing process. The two ends of the driving plate 301 in the length direction are respectively connected to the first linkage rod 304 by bolts, and the two first linkage rods 304 are respectively arranged perpendicular to the driving plate 301.

[0064] Reference Figure 10 and Figure 15 In order to accurately control the left and right movement of the driving plate 301, a control mechanism 40 is also provided on the second bracket 3. The control mechanism 40 includes a second fixed plate 401, a third connecting plate 402, a connecting rod 403, a connecting spring 404, a guide plate 405, a fourth connecting plate 406, two oppositely arranged pulleys 407 and an N-shaped frame 408 fixed on the lifting plate 201. The connecting rod 403 is horizontally arranged and there are two of them.

[0065] Reference Figure 10 and Figure 15 The second fixing plate 401 is fixed to the second bracket 3 by bolts, and the second fixing plate 401 is provided with a plug hole 4011 corresponding to the position and number of the connecting rod 403. One end of any connecting rod 403 is plugged into the plug hole 4011 of the second fixing plate 401 to form a plug-in fit, and the other end is welded and fixed to the third connecting plate 402. The connecting spring 404 is set in number corresponding to the position of the connecting rod 403. Any connecting spring 404 is sleeved on the corresponding connecting rod 403. One end of any connecting spring 404 is connected to the second fixing plate 401, and the other end is connected to the third connecting plate 402. The two connecting springs 404 are always in a stretched state during use. Any connecting rod 403 is threadedly connected to a limiting nut 4031, and the limiting nut 4031 abuts against the side of the second fixing plate 401 facing away from the third connecting plate 402. At the same time, the limiting nut 4031 can prevent the plug-in rod from detaching from the second fixing plate 401.

[0066] Reference Figure 15, two guide plates 405 are relatively provided, and the left sides of the two guide plates 405 are fixed to the third connecting plate 402 by bolts, and the right sides of the two guide plates 405 are fixed to the fourth connecting plate 406 by bolts, and a connecting pin 4061 is provided between the fourth connecting plate 406 and the driving plate 301, and the fourth connecting plate 406 and the driving plate 301 are coaxially provided with a connecting hole, and the fourth connecting plate 406 and the driving plate 301 are respectively sleeved on the connecting pin 4061 through the connecting holes. During installation, the connecting pin 4061 passes through the connecting holes of the fourth connecting plate 406 and the driving plate 301 from top to bottom and is locked by a double nut. The driving plate 301 can slide up and down on the connecting pin 4061, and the sliding stroke of the driving plate 301 on the connecting pin 4061 can be accurately adjusted by screwing the double nut on the position of the connecting pin 4061.

[0067] Reference Figure 15 and Figure 16 One end of the n-shaped frame 408 is fixedly connected to the lifting plate 201 by a bolt, and the other end is formed with a connecting rod 4081. The two ends of the connecting rod 4081 are respectively connected to the pulley 407 through bearings to form a rotation connection. A second spring 409 is provided between any pulley 407 and the connecting rod 4081. Any second spring 409 is sleeved on the connecting rod 4081, which effectively alleviates the impact force of the pulley 407 during movement and improves the stability and reliability of the equipment operation.

[0068] Reference Figure 16 , the two guide plates 405 are respectively provided with a slide groove group 50 on the opposite side for guiding the direction of the pulley 407. Since the structures of the two groups of slide groove groups 50 and the guiding methods of the pulley 407 are the same, one of the slide groove groups 50 is now used as an example for explanation.

[0069] Reference Figure 16 The chute group 50 includes a first vertical chute 501, a first inclined chute 502, a second inclined chute 503 and a second vertical chute 504 connected in sequence. The first inclined chute 502 is inclined from the upper left to the lower right, and the second inclined chute 503 is inclined from the upper right to the lower left.

[0070] Reference Figure 10 and Figure 16 When the pulley 407 moves downward along with the lifting plate 201 through the n-shaped frame 408, the pulley 407 slides in the slide groove group 50, thereby forcing the pulley 407 to circulate along a predetermined path.

[0071] Reference Figure 15 and Figure 16 At the same time, the connection spring 404 is set, and the connection spring 404 stretches or contracts according to the position of the pulley 407 in the slide groove group 50, thereby driving the third connection plate 402 and the guide plate 405 to move left and right.

[0072] Reference Figure 14 The opening and closing timing of the left opening and closing plate 103 and the right opening and closing plate 104 is controlled by the driving plate 301 to ensure that the opening and closing action is strictly performed according to the process sequence, and the accuracy and stability of the placement of the ceramic tile 90 are ensured. There are convex points arranged in an array under any left opening and closing plate 103 and any right opening and closing plate 104. The setting of the convex points can increase the distance between the left opening and closing plate 103 and the ceramic tile 90 and between the right opening and closing plate 104 and the ceramic tile 90, preventing the compressed mortar from overflowing upward and adhering to the left opening and closing plate 103 or the right opening and closing plate 104, thereby affecting the normal opening and closing operation between the left opening and closing plate 103 and the right opening and closing plate 104.

[0073] The working principle of the embodiment of the present application is as follows: in actual operation, the staff drives the driving gear 451 to rotate by operating the first motor 41, and the driving gear 451 drives the driven gear 452 to rotate through the synchronous toothed belt 453. At this time, the sliding seat 44 fixed on the synchronous toothed belt 453 also moves the conveyor frame 51 along the transmission direction, so that the conveyor frame 51 drives the trapezoidal boss 515 to move forward; First, when the substrate plate 60 is transported to the right position by the synchronous toothed belt 453, the fourth motor 84 is operated to select the scraper 83 with the highest height, and then the first electric cylinder 443 is operated to drive the connecting block 514 to drive the conveying frame 51 to extend forward, so that the slope surface on the front side of the trapezoidal boss 515 abuts against the toggle plate 73 and applies a force to the toggle plate 73 along the conveying direction. At this time, due to the limiting effect of the limiting block 741, the toggle plate 73 drives the sealing plate 74 connected to the limiting block 741 to rotate counterclockwise, and the toggle plate 73 drives the sealing plate 74 to rotate to open the glue outlet. , the adhesive is able to flow out and fall onto the substrate plate 60. As the conveyor frame 51 moves forward, the scraper 83 can evenly and stably scrape the adhesive layer 70 on the substrate plate 60. When the substrate plate 60 is fully covered with the adhesive layer 70, the piston rod of the first electric cylinder 443 is extended to its position, and the trapezoidal boss 515 is disengaged from the toggle plate 73. At this time, the sealing plate 74 is reset together with the reset torsion spring, and the first batch scraping operation is completed. At this time, if there is any adhesive residue on the scraper 83, the adhesive can be manually scraped off to the storage box 12, or the residual adhesive can be applied to the edge of the substrate plate 60 for the next scraping. Then, the fourth motor 84 is operated to select the scraper 83 at an appropriate height, and the first electric cylinder 443 is operated to drive the connecting block 514 to drive the conveyor frame 51 to retract backward, so that the scraper 83 can once again evenly and stably scrape the adhesive layer 70 on the substrate plate 60, and the slope surface on the rear side of the trapezoidal boss 515 abuts against the toggle plate 73 and applies a force to the toggle plate 73 in the retraction direction. At this time, the toggle plate 73 rotates clockwise, and the sealing plate 74 always abuts against the adhesive outlet. When the piston rod of the first electric cylinder 443 retracts into place, the second batch scraping operation is completed. At this time, if there is any adhesive residue on the scraper 83, the adhesive can be manually scraped off to the storage box 12. Next, the fourth motor 84 is operated to select the scraper 83 with the lowest height, and the first motor 41 is restarted to drive the synchronous toothed belt 453 to transport the sliding seat 44 forward. The sliding seat 44 drives the conveying frame 51 forward, so that the slope surface on the front side of the trapezoidal boss 515 abuts against the toggle plate 73 again and drives the sealing plate 74 to rotate and open the glue outlet, so that the adhesive can flow out and fall onto the substrate plate 60, and the scraper 83 evenly and stably scrapes the slurry layer 70 on the substrate plate 60. As the conveying frame 51 moves forward, the toothed blade 93 scrapes the slurry layer 70 on the substrate plate 60 to form a glue strip 80, and the third batch scraping operation is completed. Reference Figure 17 , the descent of the tile piece 90 is divided into five stages ae: When the tile piece 90 is in stage a, the substrate plate 60 that has completed the scraping operation is conveyed to the bottom of the horizontal placement plate 10. The left opening and closing plate 103 and the right opening and closing plate 104 are always in the closed state at this stage. The staff sequentially places the tile piece 90 horizontally in the guide groove 101, and then controls the first motor 41 to stop driving. At this time, the second electric cylinder 202 is controlled to drive the lifting plate 201 to drive the hollow cylinder 203 and the suction nozzle 204 to move downward. At this time, the n-shaped frame 408 connected to the lifting plate 201 also drives the pulley 407 to move downward along the first vertical groove 501 until the suction nozzle 204 descends to abut against the tile piece 90 in the guide groove 101 and sucks the tile piece 90 with air. When the tile 90 is in stage b, the second electric cylinder 202 continues to drive the lifting plate 201 to drive the hollow cylinder 203 to continue to move downward, the suction nozzle 204 remains in a fixed position, and the hollow cylinder 203 slides downward relative to the suction nozzle 204. At this time, the pulley 407 slides into the first inclined groove 502. Since the connecting spring 404 is always in a stretched state, the two guide plates 405 gradually move to the left under the action of the connecting spring 404, so that the guide plate 405 drives the driving plate 301 to move to the left through the third connecting plate 402, thereby driving the left opening and closing plate 103 and the right opening and closing plate 104 to open; When the tile 90 is in stage c, the left opening and closing plate 103 and the right opening and closing plate 104 are fully opened, and the suction nozzle 204 falls freely under the influence of the tile 90 and its own gravity, and the suction nozzle 204 drives the tile 90 to completely pass through the guide groove 101. At this time, the tile 90 is located below the left opening and closing plate 103 and the right opening and closing plate 104; When the tile 90 is in stage d, the second electric cylinder 202 continues to drive the lifting plate 201 to drive the hollow cylinder 203 and the suction nozzle 204 to move downward, and the pulley 407 slides from the end of the first inclined groove 502 into the second inclined groove 503. Since the connecting spring 404 is always in a stretched state, the two guide plates 405 gradually move to the right under the action of the connecting spring 404, so that the guide plate 405 drives the driving plate 301 to move to the right through the fourth connecting plate 406, and then drives the left opening and closing plate 103 and the right opening and closing plate 104 to gradually close. At this time, the suction nozzle 204 gradually moves downward until the lower surface of the tile 90 abuts against the upper surface of the mortar layer 70, ensuring the horizontality of the tile 90. The hollow cylinder 203 descends to abut against the upper surfaces of the left opening and closing plate 103 and the right opening and closing plate 104, and then the adsorption of all the suction nozzles 204 on the tile 90 is released at the same time by controlling the external vacuum pump; When the ceramic tile 90 is in the e stage, the left opening and closing plate 103 and the right opening and closing plate 104 are completely closed, and the second electric cylinder 202 continues to drive the lifting plate 201 to drive the hollow cylinder 203 to press down, so that the hollow cylinder 203 moves downward relative to the suction nozzle 204, and the hollow cylinder 203 presses the left opening and closing plate 103 and the right opening and closing plate 104 downward. At the same time, the n-shaped frame 408 connected to the lifting plate 201 also drives the pulley 407 to move downward along the second vertical groove 504.

[0074] When the hollow cylinder 203 drives the entire horizontally placed plate 10 to move downward, the horizontally placed plate 10 drives the driving plate 301 to move downward along the axial direction of the connecting pin shaft 4061, so that all the left opening and closing plates 103 and the right opening and closing plates 104 can simultaneously press down the ceramic tiles 90 horizontally and stably. At this time, the pressure detection device detects the pressure condition of each ceramic tile 90 and feeds back to the control system, ensuring that all ceramic tiles 90 are subjected to consistent force and the force direction is vertical, effectively avoiding slippage and tilting of the ceramic tiles 90, thereby greatly improving the accuracy of the tensile bonding strength test results and providing reliable protection for the quality inspection of ceramic tile adhesives.

[0075] After completing the pressing operation, the staff controls the second electric cylinder 202 to drive the lifting plate 201 to move the hollow cylinder 203 and the suction nozzle 204 upward. At this time, the N-shaped frame 408 connected to the lifting plate 201 also drives the pulley 407 to return along the original path of the slide group 50, so that the pulley 407 is reset.

[0076] Finally, the first motor 41 is started to drive the conveyor frame 51 to continue to transport forward, so that the staff can transfer the pressed substrate plate 60 to the work station. After the transfer is completed, the first motor 41 is started and the output shaft of the first motor 41 is rotated in the opposite direction, thereby transporting the conveyor frame 51 back to the initial position, so as to facilitate the next scraping operation.

[0077] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
