Description

Technical Field

[0001] This invention relates to the field of sintered stone production technology, and in particular to an automated production line for laying back mesh on sintered stone. Background Technology

[0002] For some large-sized slabs, a backing mesh (such as fiberglass mesh) is glued to the back to enhance their strength and toughness and reduce breakage during processing and installation. Before laying the backing mesh, adhesive is applied to the back of the slab, then the mesh is laid on top and pressed together. After the adhesive cures, the mesh is fixed to the back of the slab. Currently, the production of backing mesh on slabs is mostly done manually or with semi-automatic equipment, resulting in low production efficiency and long production times. Therefore, those skilled in the art desire a slab production line that can automatically lay the backing mesh to improve the production efficiency of backing mesh installation on slabs.

[0003] In addition, some existing fast-drying AB adhesives can cure quickly, and the applicant found that they can be used to bond backing mesh to rock slabs. However, their fast-drying characteristics cause many problems in production, and further research and design are needed on how to apply them in automated production. Summary of the Invention

[0004] The main objective of this invention is to propose an automated production line for laying back netting on slabs, aiming to solve the technical problems of low production efficiency and long production time in the existing technology, where the laying of back netting on slabs is mostly carried out manually or with semi-automatic equipment.

[0005] To achieve the above objectives, this invention proposes an automatic production line for laying back mesh on slabs, comprising a glue-spreading machine, a mesh-laying machine, a glue-rolling machine, a roller press, and a drying kiln arranged sequentially from back to front; The glue-coating machine includes a first frame, on which a glue-coating conveying device, a glue-coating left and right driving device, and a glue-coating head are provided. The glue-coating conveying device can convey rock slabs from back to front. The glue-coating head is located above the glue-coating conveying device. The glue-coating left and right driving device is connected to the glue-coating head and can drive the glue-coating head to move in the left and right direction. The glue-coating head can reciprocate left and right to coat the rock slabs with glue while the glue-coating conveying device conveys the rock slabs forward. The net laying machine includes a net laying conveyor and a net laying device. The net laying conveyor is directly opposite the adhesive coating conveyor and can convey the rock slab from back to front. The net laying device is located above the net laying conveyor and can lay the back net on the adhesive-coated rock slab. The gluing machine includes a third frame, on which a gluing conveyor and a gluing assembly are mounted. The gluing conveyor is directly opposite the netting conveyor and can convey the rock slab from back to front. The gluing assembly is located above the gluing conveyor and includes a gluing roller, a first gluing seat, a gluing motion drive device, and a gluing up-and-down drive device. The axis of the gluing roller is arranged laterally. The gluing roller is rotatably connected to the first gluing seat. The first gluing seat is drively connected to the gluing motion drive device and the gluing up-and-down drive device. The gluing up-and-down drive device can drive the gluing roller to move in the up-and-down direction, and the gluing motion drive device can drive the gluing roller to move laterally. The gluing roller can roll on the rock slab and the back net. The roller press includes a third frame, on which are mounted a roller pressing conveyor roller, an upper pressure roller, and a roller pressing lifting drive device. The axes of the upper pressure roller and the roller pressing conveyor roller are both arranged in the left-right direction. The upper pressure roller is located above the roller pressing conveyor roller. The roller pressing lifting drive device is connected to the upper pressure roller and can drive the upper pressure roller to move up and down to move closer to or away from the roller pressing conveyor roller. The roller pressing conveyor roller and the upper pressure roller can press the rock slab and back net passing between the upper pressure roller and the roller pressing conveyor roller. The drying kiln is capable of drying the rolled rock slabs and back mesh.

[0006] The slab to be coated with adhesive is conveyed forward on the adhesive coating conveyor. When the front end of the slab reaches the underside of the adhesive coating head, the head begins to dispense adhesive. Simultaneously, the adhesive coating left-right drive device drives the head to reciprocate left and right, automatically conveying the slab forward while simultaneously coating its surface with adhesive, until the rear end of the slab leaves the underside of the adhesive coating head. The coated slab is then conveyed to the mesh laying conveyor, which lays the back mesh on the coated slab. Next, the slab with the back mesh is conveyed to the glue rolling conveyor, stopping when it reaches below the glue rolling assembly. The slab continues forward onto the roller pressing conveyor rollers of the roller press. The roller pressing lifting drive device drives the upper pressure roller to press down on the slab and back mesh. While the slab is continuously conveyed forward, the upper pressure roller evenly presses over the entire back mesh in the left-right direction. The pressure from the roller pressing conveyor rollers and the upper pressure roller further disperses the adhesive and allows it to fuse more evenly with the back mesh, resulting in a smoother back mesh surface after pressing. The slabs are then conveyed to the drying kiln, where the roller-pressed slabs and back mesh are dried.

[0007] In this solution, the slabs are sequentially coated with adhesive by a glue-coating machine, laid with a back net by a net-laying machine, rolled and pressed by a glue-rolling machine and a roller press, and dried in a drying kiln. This process can automatically lay the back net on the slabs and glue it in place, which can improve production efficiency, shorten production time, and ensure that the back net is more evenly adhered to the slabs and has a smoother surface.

[0008] Preferably, the automatic rock slab back mesh laying production line further includes an upper slab transporter, a first tilting conveyor, a second tilting conveyor, and a lower slab transporter; The upper plate transporter and the first flip conveyor are both located behind the glue-applying machine. The upper plate transporter is located behind the first flip conveyor. The upper plate transporter can feed the rock slab to be laid with the back net to the first flip conveyor. The first flip conveyor can flip the rock slab so that its back faces and transport it to the glue-applying machine. The second tilting conveyor and the lower plate transporter are both located on the front side of the drying kiln. The lower plate transporter is located on the front side of the second tilting conveyor. The second tilting conveyor can receive the processed rock slabs, tilt the rock slabs to face the front, and transport them to the lower plate transporter. The lower plate transporter can remove the rock slabs from the rock slab back mesh automatic laying production line.

[0009] The upper plate conveyor is used for automatically transporting slabs of rock. The first flip conveyor flips the loaded slabs so that the back of the slabs faces up and then transports them to the front for glue application. After drying, the slabs are flipped by the second flip conveyor so that the front of the slabs faces up, and then the lower plate conveyor transports the slabs off the plate, thus realizing automatic loading and unloading of slabs.

[0010] Preferably, the automatic slab back mesh laying production line further includes a dust blower, which is located between the first tilting conveyor and the glue spraying machine. The dust blower includes a dust blower conveying device and a dust blower. The dust blower conveying device is directly opposite the first tilting conveyor and can convey slabs from back to front. The dust blower is located above the dust blower conveying device and can blow away dust on the back of the slab.

[0011] Preferably, the glue-applying head includes a glue-applying base, with a glue inlet on the upper side and multiple glue outlets on the lower side. The multiple glue outlets are arranged at intervals along the front-to-back direction. A glue flow channel is provided inside the glue-applying base. The glue inlet and the multiple glue outlets are connected through the glue flow channel. The glue flow channel includes a multi-stage diversion channel arranged vertically. The upper side of the uppermost diversion channel is connected to the glue inlet. Each diversion channel of the lowermost stage is connected to one glue outlet. One diversion channel of the upper stage is connected to two diversion channels of the lower stage.

[0012] The glue-spraying head has multiple glue outlets arranged in a front-to-back pattern. Multiple outlets spray glue onto the rock slab, increasing the spraying area, efficiency, and uniformity. Each outlet corresponds to a flow-diverting channel; the upper-level channel splits the glue into two lower-level channels, resulting in a more uniform glue flow rate across multiple channels and improving the uniformity of glue output from each outlet.

[0013] Preferably, the diversion channel is inclined in the front-to-back direction.

[0014] The distribution channels are angled, which guides the adhesive flow more smoothly, reducing buildup within the channels. Simultaneously, the angled impact force at the dispensing holes increases the flow rate and reduces residue, preventing solidification and blockage. This design is particularly suitable for applying strong, fast-drying adhesives. Furthermore, the angled distribution ensures more even adhesive coverage, guaranteeing bonding quality while reducing cleaning frequency and equipment wear, resulting in improved efficiency, reduced costs, and higher productivity.

[0015] Preferably, the first frame is further provided with a glue receiving groove, which extends in the left-right direction and is located directly below the glue application head; The upper side of the glue-coating seat is fixed with a glue inlet pipe that communicates with the glue inlet. The glue inlet pipe is equipped with a glue inlet valve that can pass glue and a liquid inlet valve that can pass cleaning liquid. During glue application, the glue inlet valve is opened and the liquid inlet valve is closed, allowing the glue to enter the glue inlet pipe and the glue flow channel for glue application. When the glue application stops, the glue inlet valve can be opened and the liquid inlet valve can be closed, allowing the cleaning liquid to enter the glue inlet pipe and the glue flow channel to flush out and clean the glue.

[0016] After the slab is coated with adhesive and leaves the underside of the adhesive applicator, some adhesive may still drip down. A receiving trough is provided to catch the dripping adhesive and prevent it from sticking to other areas. Additionally, the adhesive application and cleaning modes can be switched by changing the adhesive inlet valve and the liquid inlet valve. During production, the adhesive applicator can apply adhesive. When adhesive application stops for a period of time, if there is no continuous application, the adhesive dries quickly and needs to be cleaned promptly to prevent it from hardening and clogging, affecting subsequent production. Therefore, the liquid inlet valve is opened to allow cleaning fluid to pass through the adhesive inlet pipe, inlet port, flow channel, and outlet. The cleaning fluid dissolves and flushes out the adhesive, and the receiving trough catches the flowing adhesive and cleaning fluid.

[0017] Preferably, during the gluing process, the axis of the gluing roller is in the front-to-back direction. The gluing roller first moves from the left or right edge of the rock slab towards the center in the left-to-right direction, and the moving distance can be between 1 / 2 and 2 / 3 of the left-to-right width of the rock slab. Then, the gluing roller rises and moves to the other edge of the rock slab and then moves towards the center in the left-to-right direction, and the moving distance can be between 1 / 2 and 2 / 3 of the left-to-right width of the rock slab.

[0018] The glue roller moves along the path described above, pushing the glue from both sides of the slab towards the center. While dispersing the glue, it concentrates excess glue towards the center of the slab, providing sufficient space for further dispersion of the glue during subsequent rolling and reducing glue overflow to both sides.

[0019] Preferably, the glue rolling machine further includes a first glue washing device, which includes a first cleaning tank and a first cleaning motor. The first cleaning tank is located beside the glue rolling conveyor. The first cleaning tank can store cleaning liquid. A first cleaning roller is rotatably connected in the first cleaning tank. The first cleaning motor is drivenly connected to the first cleaning roller. The first cleaning tank and the glue rolling roller are positioned to match each other. The glue rolling roller can move into the first cleaning tank and press against the first cleaning roller. The first glue washing device also includes a second cleaning tank, which is located beside the glue conveying device. The second cleaning tank contains a brush roller and a first scraper. The second cleaning tank is also equipped with a first scraper driving device, which is connected to the first scraper. The first scraper driving device can drive the first scraper to move closer to or away from the brush roller. The second cleaning tank is positioned to match the glue roller. The glue roller can move into the second cleaning tank and press against the brush roller. When the first scraper is close to the brush roller, it can scrape across the surface of the glue roller. The first adhesive washing device further includes a first driving device, which includes a first cleaning drive motor and a first drive gear. The first cleaning drive motor is connected to the first drive gear. The first drive gear is located on the side of the second cleaning tank. A second drive gear is also fixed on the adhesive roller. The first drive gear and the second drive gear are matched and arranged. When the adhesive roller is close to the second cleaning tank, the first drive gear can mesh with the second drive gear.

[0020] After the glue roller finishes rolling, glue will remain on its surface. This glue will harden over time, especially fast-drying AB glue, which will harden very quickly. This will affect the smoothness of the roller surface, reduce the effectiveness of subsequent rolling, and is difficult to remove once hardened. This solution includes a first cleaning tank containing a cleaning solution that can dissolve the glue. After the glue roller finishes rolling, a rolling motion drive device moves the roller to the upper side of the first cleaning tank. A rolling up-and-down drive device presses the roller downwards onto the first cleaning roller. A first cleaning motor drives the first cleaning roller to rotate, which in turn rotates the roller, ensuring that the entire outer surface of the roller contacts the cleaning solution to dissolve the glue.

[0021] After the roller is cleaned in the first cleaning tank, the roller movement drive device and the roller up-and-down drive device move the roller to the upper side of the second cleaning tank and move downwards to press it onto the brush roller cotton. The first drive gear and the second drive gear approach and mesh. The first cleaning drive motor drives the roller to rotate, and the brush roller cotton can scrape the glue and cleaning liquid on the surface of the roller. At the same time, the first scraping drive device drives the first scraper to press on the roller. The first scraper can also scrape away the glue and cleaning liquid on the surface of the roller, reducing glue residue on the roller and keeping the surface of the roller flat. The first drive gear and the second drive gear separate during the roller rolling process, allowing the roller to rotate freely.

[0022] Preferably, the roller press further includes a third cleaning tank capable of storing cleaning liquid. The third cleaning tank is located on the front or rear side of the roller press conveyor roller. The third frame is equipped with a cleaning tank lifting drive device, which is connected to the third cleaning tank in a transmission manner. The cleaning tank lifting drive device can drive the third cleaning tank to move up and down. The roller press further includes a front and rear roller drive device, an upper and lower roller slide, and a front and rear roller slide. The front and rear roller slide is slidably connected to the third frame in the front and rear direction. The upper and lower roller slide is slidably connected to the front and rear roller slide in the up and down direction. The upper pressure roller is rotatably connected to the upper and lower roller slide. The roller lifting drive device is located on the front and rear roller slide. The moving end of the roller lifting drive device is connected to the upper and lower roller slide. The front and rear roller drive device is located on the third frame. The moving end of the front and rear roller drive device is connected to the front and rear roller slide. The front and rear roller drive device can drive the upper pressure roller to move in the front and rear direction to the upper side of the roller conveyor roller or the third cleaning tank. The roller press also includes a third cleaning drive motor, which is connected to the upper pressure roller in a transmission manner. When cleaning the upper pressure roller, the third cleaning drive motor can drive the upper pressure roller to rotate. The roller press further includes a second scraping drive device and a second scraping plate. The second scraping drive device is mounted on the third frame, and the second scraping plate is located on the front or rear side of the upper pressure roller. The second scraping plate is located on the upper side of the third cleaning tank. The second scraping drive device is connected to the second scraping plate in a transmission manner. The second scraping drive device can drive the second scraping plate to move closer to or away from the upper pressure roller. When the second scraping plate is close to the upper pressure roller, it can scrape across the surface of the upper pressure roller.

[0023] After the upper pressure roller passes over the back mesh, adhesive will adhere to its surface. This adhesive will harden over time, especially fast-drying AB adhesive, which will harden very quickly. This will affect the flatness of the upper pressure roller surface, reduce the effectiveness of subsequent roller presses, and is difficult to remove once hardened. This solution includes a third cleaning tank containing a cleaning solution that can dissolve the adhesive. After the upper pressure roller passes over the rock slab, the roller lifting drive first moves the upper pressure roller upwards. Then, the roller front and rear drive moves the upper pressure roller above the third cleaning tank. Next, the roller lifting drive moves the upper pressure roller downwards, and the cleaning tank lifting drive moves the third cleaning tank upwards. This immerses the lower side of the upper pressure roller in the cleaning solution of the third cleaning tank. Then, the third cleaning drive motor rotates the upper pressure roller, immersing its entire outer circumference in the cleaning solution, which dissolves the adhesive. When the upper pressure roller is being cleaned, the second scraper drive device drives the second scraper to press on the upper pressure roller. The second scraper can scrape off the glue and cleaning liquid on the surface of the upper pressure roller, reducing the glue residue on the upper pressure roller and keeping the surface of the upper pressure roller flat.

[0024] Preferably, the third frame is further provided with a cleaning transmission lifting drive device and a third cleaning lifting slide. The third cleaning lifting slide is slidably connected to the third frame in the vertical direction. The cleaning transmission lifting drive device is driven to the third cleaning lifting slide. The cleaning transmission lifting drive device can drive the third cleaning lifting slide to move up and down. The third cleaning drive motor is fixed on the third cleaning lifting slide. A third drive gear is fixedly connected to the output shaft of the third cleaning drive motor. A fourth drive gear is fixedly connected to the upper pressure roller. The third drive gear and the fourth drive gear are matched and configured so that the third drive gear and the fourth drive gear can approach and mesh when cleaning the upper pressure roller.

[0025] When the upper pressure roller is being cleaned, the cleaning transmission lifting drive device can drive the third cleaning drive motor and the third drive gear to move upward, causing the third drive gear to approach and mesh with the fourth drive gear. The third cleaning drive motor can then drive the upper pressure roller to rotate. The third drive gear and the fourth drive gear separate during rolling, allowing the upper pressure roller to rotate freely as the rock slab is conveyed. Attached Figure Description

[0033] like Figures 1 to 12 As shown, an automatic slab back mesh laying production line includes a glue-spreading machine 2, a mesh laying machine 3, a glue-rolling machine 4, a roller press 5, and a drying kiln 6 arranged sequentially from back to front.

[0034] The glue-coating machine 2 includes a first frame 21, on which a glue-coating conveying device 22, a glue-coating left-right drive device 232, and a glue-coating head 233 are mounted. The glue-coating conveying device 22 can convey rock slabs from back to front. The glue-coating head 233 is located above the glue-coating conveying device 22. The glue-coating left-right drive device 232 is connected to the glue-coating head 233 and can drive the glue-coating head 233 to move in the left-right direction. The glue-coating head 233 can reciprocate left and right to coat the rock slabs with glue while the glue-coating conveying device 22 conveys the rock slabs forward. The glue-coating left-right drive device 232 can be a gear and rack motion module or a synchronous belt and synchronous pulley motion module, etc. The glue-coating conveying device 22 includes a conveying motor and multiple conveying rollers 221 arranged at intervals in the front-back direction. The multiple conveying rollers 221 are connected to the conveying motor and support the plates. The rotation of the conveying rollers 221 can convey the plates.

[0035] The net-laying machine 3 includes a net-laying conveyor and a net-laying machine 3. The net-laying conveyor is positioned opposite the adhesive-coated conveyor 22 and is capable of conveying the rock slab from back to front. The net-laying device is located above the net-laying conveyor and is capable of laying the back net onto the adhesive-coated rock slab. The net-laying machine 3 is comparable to existing net-laying machines 3, including feeding, cutting, and pressing the back net onto the rock slab.

[0036] The gluing machine 4 includes a third frame 51, on which a gluing conveyor 42 and a gluing assembly 43 are mounted. The gluing conveyor 42 is directly opposite the netting conveyor and can convey the rock slab from back to front. The gluing assembly 43 is located above the gluing conveyor 42. The gluing assembly 43 includes a gluing roller 431, a first gluing seat 432, a gluing motion drive device, and a gluing up-and-down drive device 435. The axis of the gluing roller 431 is arranged laterally. The gluing roller 431 is rotatably connected to the first gluing seat 432. The first gluing seat 432 is connected to the gluing motion drive device and the gluing up-and-down drive device 435. The gluing up-and-down drive device 435 can drive the gluing roller 431 to move in the up-and-down direction. The gluing motion drive device can drive the gluing roller 431 to move laterally. The gluing roller 431 can roll on the rock slab and the back net. Taking the axis of the rubber roller 431 along the front-to-back direction as an example, the rubber roller 431 rolls on the rock slab in the left-to-right direction. The width and length of the rolling range of the rubber roller 431 in one left-to-right movement correspond to the length of the rubber roller 431 and the width of the rock slab, respectively. The rubber rolling motion drive device and the rubber rolling up-and-down drive device 435 work together to make the rubber roller 431 move multiple times in the front-to-back direction to cover and roll the entire surface of the rock slab and the back net. The rubber rolling conveying device 42 can be a belt conveyor mechanism. The rock slab can be placed flat on the belt, with a support plate on the underside of the belt. The front of the rock slab is facing down, and the back of the rock slab and the back net are facing up.

[0037] The roller press 5 includes a third frame 51, on which are mounted a roller conveyor roller 53, an upper pressure roller 52, and a roller lifting drive device 541. The axes of the upper pressure roller 52 and the roller conveyor roller 53 are both arranged in a left-right direction. The upper pressure roller 52 is located above the roller conveyor roller 53. The roller lifting drive device 541 is connected to the upper pressure roller 52 and can be a cylinder. The roller lifting drive device 541 can drive the upper pressure roller 52 to move up and down to approach or move away from the roller conveyor roller 53. The roller conveyor roller 53 and the upper pressure roller 52 can roller press the rock slab and back net passing between the upper pressure roller 52 and the roller conveyor roller 53. The roller conveyor roller 53 can be connected to a conveyor motor, which can drive the roller conveyor roller 53 to rotate to convey the rock slab.

[0038] Drying kiln 6 is capable of drying the rolled slabs and back mesh. Drying kiln 6 can be an existing drying kiln 6 used for heating and drying ceramic slabs.

[0039] The slab to be coated with adhesive is conveyed forward on the adhesive coating conveyor 22. When the front end of the slab reaches the underside of the adhesive coating head 233, the adhesive coating head 233 begins to dispense adhesive. Simultaneously, the adhesive coating left-right drive device 232 drives the adhesive coating head 233 to reciprocate left and right, automatically conveying the slab forward and simultaneously coating its surface with adhesive, until the rear end of the slab leaves the underside of the adhesive coating head 233. The coated slab is then conveyed to the mesh laying conveyor, which lays the back mesh on the coated slab. Next, the slab with the back mesh is conveyed to the glue rolling conveyor 42, and the conveying stops when the slab reaches below the glue rolling assembly 43. The slab is then continuously conveyed forward to the roller conveyor roller 53 of the roller press 5. The roller pressing lifting drive device 541 drives the upper pressure roller 52 to press down on the slab and the back net. While the slab is continuously conveyed forward, the upper pressure roller 52 presses evenly over the entire back net in the left-right direction. The slab and the back net are pressed together by the roller conveyor roller 53 and the upper pressure roller 52, which further disperses the glue and makes it more evenly integrated with the back net. After pressing, the surface of the back net is smoother. Then the slab is conveyed to the drying kiln 6, where the roller-pressed slab and the back net are dried.

[0040] In this scheme, the slab passes through the glue-spraying machine 2 for glue application, the back netting machine 3 for back netting, the glue-rolling machine 4 and the roller press 5 for glue rolling and roller pressing, and the drying kiln 6 for drying. This can automatically lay the back netting on the slab and glue it in place, which can improve production efficiency and shorten production time. At the same time, the back netting is more evenly pasted and fixed on the slab, and the surface of the back netting is flatter.

[0041] In some specific embodiments, the automatic slab back mesh laying production line also includes an upper slab transporter 11, a first tilting conveyor 12, a second tilting conveyor 71, and a lower slab transporter 72; The upper plate transporter 11 and the first flip conveyor 12 are both located behind the glue spreading machine 2. The upper plate transporter 11 is located behind the first flip conveyor 12. The upper plate transporter 11 can load the rock slab to be laid with the back net onto the first flip conveyor 12. The first flip conveyor 12 can flip the rock slab so that its back faces and transport it to the glue spreading machine 2. The second tilting conveyor 71 and the lower plate transporter 72 are both located on the front side of the drying kiln 6. The lower plate transporter 72 is located on the front side of the second tilting conveyor 71. The second tilting conveyor 71 can receive the processed rock slabs, tilt the rock slabs to face the front and transport them to the lower plate transporter 72. The lower plate transporter 72 can remove the rock slabs from the rock slab back mesh automatic laying production line.

[0042] The upper plate conveyor 11 is used for automatically conveying slabs of ceramic slabs. The first tilting conveyor 12 can tilt the loaded slabs so that the back side of the slabs faces upwards and then convey them to the front side for adhesive application. After drying, the slabs are tilted by the second tilting conveyor 71 so that the front side of the slabs faces upwards, and then the lower plate conveyor 72 moves the slabs out of the machine, realizing automatic loading and unloading of the slabs. The upper plate conveyor 11 and the lower plate conveyor 72 can adopt existing mechanisms for handling ceramic slabs, and can use a multi-axis motion module in conjunction with a vacuum suction cup to pick up the front side of the slab for handling. The first tilting conveyor 12 and the second tilting conveyor 71 can adopt existing mechanisms for tilting ceramic slabs.

[0043] Furthermore, the automatic slab back mesh laying production line also includes a dust blower 13. The dust blower 13 is located between the first tilting conveyor 12 and the glue applicator 2. The dust blower 13 includes a dust blower conveying device and a dust blower. The dust blower conveying device is directly opposite the first tilting conveyor 12 and can convey slabs from back to front. The dust blower is located above the dust blower conveying device and can blow away the dust on the back of the slab, increasing the adhesion between the glue and the back of the slab.

[0044] In some specific embodiments, reference is made to Figure 4 The glue-applying head 233 includes a glue-applying base 2331. The glue-applying base 2331 has a glue inlet 2332 on its upper side and multiple glue outlet holes 2333 on its lower side. The multiple glue outlet holes 2333 are arranged at intervals in the front-back direction. The glue-applying base 2331 has a glue flow channel 2334. The glue inlet 2332 and the multiple glue outlet holes 2333 are connected through the glue flow channel 2334. The glue flow channel 2334 includes a multi-stage diversion channel 23341 arranged in an upper and lower direction. The upper side of the uppermost diversion channel 23341 is connected to the glue inlet 2332. Each diversion channel 23341 of the lowermost stage is connected to one glue outlet hole 2333. One diversion channel 23341 of the upper stage is connected to two diversion channels 23341 of the lower stage.

[0045] The glue-applying head 233 has multiple glue outlets 2333 arranged in a front-to-back pattern. These multiple outlets apply glue to the rock slab, increasing the application area, efficiency, and uniformity. Each outlet corresponds to a diversion channel 23341. The upper-level diversion channel 23341 branches into two lower-level diversion channels 23341, resulting in a more uniform glue flow rate across the multi-stage diversion channels 23341 and improving the uniformity of glue output from each outlet.

[0046] Furthermore, the diversion channel 23341 is inclined in the front-to-back direction.

[0047] The existing glue applicator 233 has channels that extend vertically and horizontally; specifically, channels within the same level extend horizontally, while channels connecting upper and lower levels extend vertically. This design presents significant drawbacks in practical applications: Due to the vertical and horizontal arrangement of the channels, some glue accumulates at the outlet and within the internal channels during the application process due to gravity and other factors. Furthermore, the vertical and horizontal arrangement results in a relatively unidirectional flow of glue, easily creating dead zones. This leads to glue solidification and blockage of the glue holes and internal channels, especially with strong, fast-drying glues such as fast-drying AB glue. Blockage not only affects the uniformity of glue application, causing weak adhesion between the slab and the backing mesh, and localized delamination, but also necessitates frequent disassembly of the glue applicator 233 for cleaning, increasing labor costs and downtime, reducing production efficiency, and in severe cases, damaging the glue applicator 233 and increasing equipment wear and tear costs.

[0048] The diversion channel 23341 is angled, which guides the adhesive flow more smoothly within it, reducing accumulation. Simultaneously, the adhesive has a slight impact force as it flows out of the dispensing hole 2333, increasing flow and reducing residue, thus preventing solidification and blockage. This design is more suitable for applying strong, fast-drying adhesives. Furthermore, the angled distribution of the diversion channel 23341 ensures more even adhesive coverage, guaranteeing bonding quality while reducing cleaning frequency and equipment wear, achieving improved efficiency, reduced costs, and lower consumption.

[0049] In some specific embodiments, reference is made to Figure 2 and Figure 3 The first frame 21 is also provided with a glue receiving groove 27, which extends in the left and right direction and is located directly below the glue spraying head 233. The glue-coating base 2331 has a glue inlet pipe 283 fixed on its upper side, which communicates with the glue inlet 2332. The glue inlet pipe 283 is equipped with a glue inlet valve 281 that can pass glue and a cleaning liquid inlet valve 282 that can pass cleaning liquid. The glue pump is connected to the glue inlet valve 281 through a pipe, and the cleaning liquid pump is connected to the cleaning liquid inlet valve 282 through a pipe.

[0050] During glue application, glue inlet valve 281 is opened and liquid inlet valve 282 is closed, allowing glue to enter glue inlet pipe 283 and glue flow channel 2334 for glue application. When the glue application stops, the glue inlet valve 281 can be opened and the liquid inlet valve 282 can be closed, allowing the cleaning liquid to enter the glue inlet pipe 283 and the glue flow channel 2334 to flush out and clean the glue.

[0051] After the slab is coated with adhesive and leaves the underside of the adhesive head 233, some adhesive may still drip down from the adhesive head 233. The adhesive receiving tank 27 can catch the dripping adhesive to prevent it from sticking to other places. In addition, the adhesive coating state and the cleaning state can be switched by switching the adhesive inlet valve 281 and the liquid inlet valve 282. During production adhesive coating, the adhesive head 233 can coat adhesive. When adhesive coating stops for a period of time, if there is no continuous adhesive coating, the adhesive dries quickly and needs to be cleaned in time to prevent the adhesive from solidifying and clogging and affecting subsequent normal production. Therefore, the liquid inlet valve 282 is opened to allow the cleaning liquid to pass through the adhesive inlet pipe 283, adhesive inlet 2332, adhesive flow channel 2334 and adhesive outlet 2333. The cleaning liquid can dissolve and flush out the adhesive. The adhesive receiving tank 27 can catch the flowing adhesive and cleaning liquid.

[0052] In some specific embodiments, during the gluing process, the axis of the gluing roller 431 is in the front-to-back direction. The gluing roller 431 first moves and rolls from the left or right edge of the slab towards the center in the left-to-right direction. The moving distance can be between 1 / 2 and 2 / 3 of the left-to-right width of the slab. Then, the gluing roller 431 rises and moves to the other edge of the slab and then moves and rolls towards the center in the left-to-right direction. The moving distance can be between 1 / 2 and 2 / 3 of the left-to-right width of the slab.

[0053] The glue roller 431 moves along the path described above, which can push the glue from the left and right sides of the slab towards the center. While dispersing the glue, it concentrates the excess glue towards the center of the slab, providing sufficient dispersion space for further dispersion of the glue during subsequent rolling and reducing glue overflow to both sides.

[0054] In some specific embodiments, there are two sets of roller adhesive assembly 43, arranged in a front-to-back direction. The two sets of roller adhesive assembly 43 arranged in a front-to-back direction can simultaneously apply roller adhesive to the front and rear areas of the slab, improving the efficiency of applying roller adhesive to the entire surface of the slab.

[0055] In some specific embodiments, reference is made to Figure 7 The glue-rolling motion drive device includes a front-to-back glue-rolling drive device 433 and a left-to-right glue-rolling drive device 434. The front-to-back glue-rolling drive device 433 is mounted on the second frame 41, the left-to-right glue-rolling drive device 434 is mounted on the moving end of the front-to-back glue-rolling drive device 433, and the up-and-down glue-rolling drive device 435 is mounted on the moving end of the left-to-right glue-rolling drive device 434. The first glue-rolling seat 432 and the glue-rolling roller 431 are mounted on the moving end of the up-and-down glue-rolling drive device 435. The front-to-back glue-rolling drive device 433 and the left-to-right glue-rolling drive device 434 can respectively drive the glue-rolling roller 431 to move in the front-to-back direction and the left-to-right direction. The front-to-back glue-rolling drive device 433, the left-to-right glue-rolling drive device 434, and the up-and-down glue-rolling drive device 435 can be adopted as a screw motion module, a gear and rack motion module, or a synchronous pulley and synchronous belt motion module, etc.

[0056] Furthermore, the roller assembly 43 also includes a second roller seat 436, which is located on the upper side of the first roller seat 432. A buffer spring 437 is provided between the first roller seat 432 and the second roller seat 436. The second roller seat 436 is located on the moving end of the roller up and down drive device 435.

[0057] When the roller roller 431 moves downwards driven by the roller roller drive device 435, after the roller roller 431 presses against the rock slab, the first roller roller seat 432 and the second roller roller seat 436 move closer to each other. The first roller roller seat 432 and the second roller roller seat 436 are buffered by the buffer spring 437. On the one hand, the roller roller 431 can be kept close to the back net, and on the other hand, damage to the rock slab or the back net can be avoided.

[0058] In some specific embodiments, reference is made to Figure 8 and Figure 9 The roller glue machine 4 also includes a first glue washing device, which includes a first cleaning tank 441 and a first cleaning motor 442. The first cleaning tank 441 is located next to the roller glue conveying device 42. The first cleaning tank 441 can store cleaning liquid. A first cleaning roller 443 is rotatably connected in the first cleaning tank 441. The first cleaning motor 442 is drivenly connected to the first cleaning roller 443. The first cleaning tank 441 and the roller glue 431 are matched in position. The roller glue 431 can move into the first cleaning tank 441 and press on the first cleaning roller 443. The first glue washing device also includes a second washing tank 451, which is located beside the glue conveying device 42. The second washing tank 451 is provided with a brush roller cotton 452 and a first scraper plate 461. The second washing tank 451 is also provided with a first scraper drive device 462, which is connected to the first scraper plate 461. The first scraper drive device 462 can be a cylinder. The first scraper drive device 462 can drive the first scraper plate 461 to move closer to or away from the brush roller cotton 452. The second washing tank 451 is matched with the glue roller 431. The glue roller 431 can move into the second washing tank 451 and press on the brush roller cotton 452. When the first scraper plate 461 is close to the brush roller cotton 452, it can scrape the surface of the glue roller 431. The first adhesive washing device also includes a first driving device, which includes a first cleaning drive motor 471 and a first drive gear 472. The first cleaning drive motor 471 and the first drive gear 472 are connected in transmission. The first drive gear 472 is located on the side of the second cleaning tank 451. A second drive gear 4311 is also fixed on the adhesive roller 431. The diameter of the adhesive roller 431 is larger than the outer diameter of the second drive gear 4311. The first drive gear 472 and the second drive gear 4311 are matched and configured so that the first drive gear 472 can mesh with the second drive gear 4311 when the adhesive roller 431 is close to the second cleaning tank 451.

[0059] After the glue roller 431 finishes rolling, glue will adhere to its surface. This glue will harden over time, especially fast-drying AB glue, which will harden quickly, affecting the smoothness of the roller 431's surface and reducing the effectiveness of subsequent rolling. Once hardened, it is also difficult to remove. This solution includes a first cleaning tank 441 containing a cleaning solution that can dissolve the glue. After the roller 431 finishes rolling, the rolling motion drive device moves the roller 431 to the upper side of the first cleaning tank 441. The rolling up-and-down drive device 435 presses the roller 431 downwards onto the first cleaning roller 443. The first cleaning motor 442 drives the first cleaning roller 443 to rotate, which in turn drives the roller 431 to rotate, ensuring that the entire outer circumference of the roller 431 contacts the cleaning solution, dissolving the glue.

[0060] After the glue-rolling roller 431 is cleaned in the first cleaning tank 441, the glue-rolling motion drive device and the glue-rolling up-and-down drive device 435 drive the glue-rolling roller 431 to move to the upper side of the second cleaning tank 451 and move downward to press on the brush roller cotton 452. The first drive gear 472 and the second drive gear 4311 approach and mesh. The first cleaning drive motor 471 drives the glue-rolling roller 431 to rotate. The brush roller cotton 452 can scrape the glue and cleaning liquid on the surface of the glue-rolling roller 431. At the same time, the first scraping drive device 462 drives the first scraper 461 to press on the glue-rolling roller 431. The first scraper 461 can also scrape off the glue and cleaning liquid on the surface of the glue-rolling roller 431, reducing the glue residue on the glue-rolling roller 431 and keeping the surface of the glue-rolling roller 431 flat. The first drive gear 472 and the second drive gear 4311 separate during glue rolling, and the glue-rolling roller 431 can rotate freely during glue rolling.

[0061] In some specific embodiments, reference is made to Figures 10 to 12 The roller press 5 also includes a third cleaning tank 55 that can store cleaning liquid. The third cleaning tank 55 is located on the front or rear side of the roller press conveyor roller 53. The third frame 51 is equipped with a cleaning tank lifting drive device 551. The cleaning tank lifting drive device 551 is connected to the third cleaning tank 55 in a transmission. The cleaning tank lifting drive device 551 can be a cylinder. The cleaning tank lifting drive device 551 can drive the third cleaning tank 55 to move up and down. The roller press 5 also includes a front and rear roller drive device 542, an upper and lower roller slide 543, and a front and rear roller slide 544. The front and rear roller slide 544 is slidably connected to the third frame 51 in the front and rear direction. The upper and lower roller slide 543 is slidably connected to the front and rear roller slide 544 in the up and down direction. The upper pressure roller 52 is rotatably connected to the upper and lower roller slide 543. The roller lifting drive device 541 is located on the front and rear roller slide 544. The moving end of the roller lifting drive device 541 is connected to the upper and lower roller slide 543. The front and rear roller drive device 542 is located on the third frame 51. The front and rear roller drive device 542 can be a cylinder. The moving end of the front and rear roller drive device 542 is connected to the front and rear roller slide 544. The front and rear roller drive device 542 can drive the upper pressure roller 52 to move in the front and rear direction to the upper side of the roller conveyor roller 53 or the third cleaning tank 55. The roller press 5 also includes a third cleaning drive motor 561, which is connected to the upper pressure roller 52 in a transmission manner. When cleaning the upper pressure roller 52, the third cleaning drive motor 561 can drive the upper pressure roller 52 to rotate.

The second scraping drive device 571 is mounted on the third frame 51, and the second scraping plate 572 is mounted on the front or rear side of the upper pressure roller 52. The second scraping plate 572 is mounted on the upper side of the third cleaning tank 55. The second scraping drive device 571 and the second scraping plate 572 are connected in a transmission. The second scraping drive device 571 can be a cylinder. The second scraping drive device 571 can drive the second scraping plate 572 to move closer to or away from the upper pressure roller 52. When the second scraping plate 572 is close to the upper pressure roller 52, it can scrape across the surface of the upper pressure roller 52.

[0062] After the upper pressure roller 52 presses over the back mesh, adhesive will adhere to its surface. This adhesive will harden over time, especially fast-drying AB adhesive, which will harden quickly, affecting the smoothness of the upper pressure roller 52 surface and reducing the effectiveness of subsequent roller presses. Once hardened, it is also difficult to remove. This solution includes a third cleaning tank 55 containing a cleaning solution that can dissolve the adhesive. After the upper pressure roller 52 presses over the rock slab, the roller pressing lifting drive device 541 first drives the upper pressure roller 52 upwards. Then, the roller pressing front and rear drive device 542 moves the upper pressure roller 52 above the third cleaning tank 55. Next, the roller pressing lifting drive device 541 drives the upper pressure roller 52 downwards, and the cleaning tank lifting drive device 551 drives the third cleaning tank 55 upwards. This immerses the lower side of the upper pressure roller 52 in the cleaning solution of the third cleaning tank 55. Then, the third cleaning drive motor 561 drives the upper pressure roller 52 to rotate, immersing the entire outer circumference of the upper pressure roller 52 in the cleaning solution, which dissolves the adhesive. When the upper pressure roller 52 is being cleaned, the second scraper drive device 571 drives the second scraper plate 572 to press against the upper pressure roller 52. The second scraper plate 572 can scrape off the glue and cleaning liquid on the surface of the upper pressure roller 52, reducing the amount of glue residue on the upper pressure roller 52 and keeping the surface of the upper pressure roller 52 flat. After cleaning, the roller lifting drive device 541 drives the upper pressure roller 52 upward, and the cleaning tank lifting drive device 551 drives the third cleaning tank 55 downward below the upper side of the roller conveyor roller 53 to avoid obstructing the conveying of the next piece of board.

[0063] Furthermore, the third frame 51 is also equipped with a cleaning transmission lifting drive device 562 and a third cleaning lifting slide 563. The third cleaning lifting slide 563 is slidably connected to the third frame 51 in the vertical direction. The cleaning transmission lifting drive device 562 is connected to the third cleaning lifting slide 563 in a transmission manner. The cleaning transmission lifting drive device 562 can be a cylinder. The cleaning transmission lifting drive device 562 can drive the third cleaning lifting slide 563 to move up and down. The third cleaning drive motor 561 is fixed on the third cleaning lifting slide 563. A third drive gear 564 is fixedly connected to the output shaft of the third cleaning drive motor 561. A fourth drive gear 521 is fixedly connected to the upper pressure roller 52. The third drive gear 564 and the fourth drive gear 521 are matched and set so that the third drive gear 564 and the fourth drive gear 521 can approach and mesh when cleaning the upper pressure roller 52.

[0064] When the upper pressure roller 52 is cleaning, the cleaning transmission lifting drive device 562 can drive the third cleaning drive motor 561 and the third drive gear 564 to move upward, so that the third drive gear 564 and the fourth drive gear 521 approach and mesh, and the third cleaning drive motor 561 can drive the upper pressure roller 52 to rotate. The third drive gear 564 and the fourth drive gear 521 separate during rolling, and the upper pressure roller 52 can rotate freely with the conveying of the rock slab.

[0065] Furthermore, a second lower idler roller 58 is rotatably connected to the third frame 51. The second lower idler roller 58 is located behind the roller conveyor roller 53, and a third cleaning tank 55 is located between the roller conveyor roller 53 and the second lower idler roller 58.
