Description

Technical Field

[0001] This utility model relates to the technical field of mosaic board production equipment, and in particular to a rolling mechanism and a screen pasting machine. Background Technology

[0002] In mosaic tile production, the mosaic tiles are arranged into a mold, then a mesh is applied with adhesive and laid on top of the tiles. At this point, the mesh needs to be pressed firmly onto the mosaic tiles again to improve adhesion. Currently, a pressure roller is typically used to roll the mesh from one end of the mold to the other. However, after prolonged rolling, the adhesive on the roller dries and becomes increasingly sticky. When the roller starts rolling again from one end of the mold, one end of the mesh can easily become entangled and stick to the roller, resulting in the mesh not adhering to the mosaic tiles or the mesh shifting. Therefore, there is an urgent need for a rolling mechanism that can improve the rolling effect of the mesh. Utility Model Content

[0003] The purpose of this utility model is to provide a rolling mechanism and a screen pasting machine to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is:

[0005] A rolling mechanism includes: a conveying device; and a rolling assembly including a fixed frame, a pressure roller, a scraper, and a recycling trough. The pressure roller, the scraper, and the recycling trough are respectively disposed on the fixed frame. The pressure roller is located above the conveying device. The scraper is used to collect the glue on the outer surface of the pressure roller. The recycling trough is located below the scraper.

[0006] This technical solution has at least the following beneficial effects: The conveying device is used to transport the external mold, and the mold can be loaded with mosaic pieces after the mesh fabric has been laid. When the conveying device drives the mold past the pressure roller, the pressure roller rolls the mesh fabric on the top surface, so that the mesh fabric is further bonded to the mosaic pieces. After the pressure roller completes one or more rolls, the glue on the surface of the pressure roller can be collected using a scraper. The glue collected on the scraper flows into the collection tank below under the action of gravity, and the glue is collected in the collection tank. This can remove the glue on the surface of the pressure roller in time, reduce the stickiness of the pressure roller surface after rolling, and effectively prevent the pressure roller from sticking the mesh fabric or causing the mesh fabric to shift when rolling it, thereby improving the rolling effect of the mesh fabric and the final product quality.

[0007] As a further improvement to the above technical solution, the scraper blade abuts against the outer circumferential surface of the pressure roller, and a first motor is provided on the fixing frame, the first motor being connected to the pressure roller in a driving connection.

[0008] As a further improvement to the above technical solution, the fixed frame is provided with a transition roller, a lifting device and a second motor. The transition roller is located above the pressure roller. The second motor is driven and connected to the transition roller. The scraper blade abuts against the outer circumferential surface of the transition roller. The lifting device is driven and connected to the pressure roller. The lifting device can drive the pressure roller to move upward and make the pressure roller abut against the transition roller, or drive the pressure roller to move downward and make the pressure roller move away from the transition roller.

[0009] As a further improvement to the above technical solution, the lifting device includes a linear drive component, which can drive the lifting seat to move up and down, and the pressure roller is connected to the lifting seat.

[0010] As a further improvement to the above technical solution, the lifting device includes a rotary drive component and a fork mounted on the fixed frame. The rotary drive component is connected to the fork in a driving manner. The rotary drive component can drive the fork to rotate closer to or away from the transition roller. The fork is provided with a transmission groove extending toward the rotation axis of the fork. The fixed frame is provided with a guide groove extending in the vertical direction. The end of the pressure roller passes through the transmission groove and the guide groove.

[0011] As a further improvement to the above technical solution, the fixing frame is provided with a straight groove extending in the horizontal direction, and the guide grooves are respectively provided at both ends of the straight groove.

[0012] As a further improvement to the above technical solution, the fixing frame is provided with a connecting pipe, and the connecting pipe is provided with a plurality of atomizing nozzles facing the transition roller.

[0013] As a further improvement to the above technical solution, one end of the recycling tank is provided with a liquid inlet, and the other end of the recycling tank is provided with a liquid outlet.

[0014] As a further improvement to the above technical solution, a sponge layer is provided on the outer periphery of the pressure roller.

[0015] A screen pasting machine includes the aforementioned rolling mechanism.

[0016] The technical solution has at least the following beneficial effects: In this mesh applicator, the above-mentioned rolling mechanism is used to further roll the applied mesh. Since the rolling mechanism can remove the glue on the surface of the pressure roller in time, it reduces the stickiness of the pressure roller surface after rolling, effectively preventing the pressure roller from sticking the mesh or causing the mesh to shift when rolling the mesh, thereby improving the rolling effect of the mesh and the final product quality.

[0030] Reference Figure 1 A rolling mechanism includes a conveying device 100 and a rolling assembly. The conveying device 100 is mainly used for conveying the mold and can be a chain conveyor, belt conveyor, or roller conveyor. The rolling assembly includes a fixed frame 210, a pressure roller 220, a glue scraper 230, and a recovery trough 240. The pressure roller 220, the glue scraper 230, and the recovery trough 240 are respectively disposed on the fixed frame 210. The pressure roller 220 is located above the conveying device 100. The glue scraper 230 is used to recover the glue on the surface of the pressure roller 220. The recovery trough 240 is located below the glue scraper 230. Naturally, the pressure roller 220 is rotatably connected to the fixed frame 210, so that when the mold passes through the pressure roller 220, the pressure roller 220 can both roll the mesh on the mold and reduce the friction between the mold and the mesh.

[0031] As described above, the conveying device 100 is used to convey the mold of the external device. The mold can be loaded with mosaic pieces after the mesh fabric has been laid. When the conveying device 100 drives the mold past the pressure roller 220, the pressure roller 220 rolls the mesh fabric on the top surface, so that the mesh fabric is further bonded to the mosaic pieces. After the pressure roller 220 completes one or more rolls, the glue scraper 230 can be used to collect the glue on the surface of the pressure roller 220. The glue collected on the glue scraper 230 flows into the collection tank 240 below under the action of gravity. The glue is collected in the collection tank 240. In this way, the glue on the surface of the pressure roller 220 can be removed in time, reducing the stickiness of the surface of the pressure roller 220 after rolling. This effectively prevents the pressure roller 220 from sticking the mesh fabric or causing the mesh fabric to shift when rolling the mesh fabric, thereby improving the rolling effect of the mesh fabric and the final product quality.

[0032] There are several ways for the scraper blade 230 to recover the adhesive on the surface of the pressure roller 220. In Embodiment 1, the scraper blade 230 abuts against the outer circumferential surface of the pressure roller 220, and a first motor is mounted on the fixing frame 210, which drives the pressure roller 220. In this embodiment, the scraper blade 230 is in direct contact with the pressure roller 220. During operation, the first motor drives the pressure roller 220 to rotate, causing the outer circumferential surface of the pressure roller 220 to move relative to the scraper blade 230. The scraper blade 230 then scrapes off the adhesive adhering to the outer circumferential surface of the pressure roller 220, thus achieving the recovery of the adhesive on the surface of the pressure roller 220 by the scraper blade 230.

[0033] As a second embodiment of recycling adhesive from the surface of the pressure roller 220 by the scraper blade 230, such as Figure 2 and Figure 3As shown, the fixed frame 210 is equipped with a transition roller 270, a lifting device and a second motor. The transition roller 270 is located above the pressure roller 220. The second motor is driven to the transition roller 270. The scraper blade 230 abuts against the outer circumferential surface of the transition roller 270. The lifting device is driven to the pressure roller 220. The lifting device can drive the pressure roller 220 to move upward and abut against the transition roller 270, or drive the pressure roller 220 to move downward and move away from the transition roller 270. In this embodiment, the pressure roller 220 is not equipped with an active rotation driving force. When it is necessary to remove the glue from the outer periphery of the pressure roller 220, the lifting device drives the pressure roller 220 to move upward, so that the pressure roller 220 abuts against the transition roller 270. Then, the second motor drives the transition roller 270 to rotate. Since the pressure roller 220 abuts against the transition roller 270, when the transition roller 270 rotates, it can drive the pressure roller 220 to rotate, so that the glue on the outer periphery of the pressure roller 220 is transferred to the outer periphery of the transition roller 270. At this time, the glue scraper 230 abuts against the outer peripheral surface of the transition roller 270 and can scrape off the glue adhering to the outer periphery of the transition roller 270. In this way, the glue scraper 230 can recycle the glue on the surface of the pressure roller 220. After the glue removal of the pressure roller 220 is completed, the lifting device drives the pressure roller 220 to move downward, so that the pressure roller 220 leaves the transition roller 270 and moves down to reset, in preparation for the next rolling of the mesh fabric.

[0034] In Embodiment 2, there are several ways in which the lifting device drives the pressure roller 220 to move up and down, such as... Figure 2 As shown, in this embodiment, the lifting device includes a linear drive 250, which drives the lifting seat to move up and down. The pressure roller 220 is connected to the lifting seat. In this case, the linear drive 250 directly drives the lifting seat to move linearly up and down, causing the pressure roller 220 to move directly upwards towards the transition roller 270 or linearly downwards away from the transition roller 270. In practical applications, the linear drive 250 can be an electric lead screw, a pneumatic cylinder, or a hydraulic cylinder, etc.

[0035] In Embodiment 2, there are several ways in which the lifting device drives the pressure roller 220 to move up and down, such as... Figure 3As shown, in this embodiment, the lifting device includes a rotary drive component and a fork 260 mounted on the fixed frame 210. The rotary drive component is connected to the fork 260. The rotary drive component can drive the fork 260 to rotate closer to or away from the transition roller 270. In practical applications, the rotary drive component can have various structural forms. It can be a third motor that directly drives the fork 260 to rotate, or it can use a cylinder, electric screw, or hydraulic cylinder as a drive source. The two ends of the drive source are rotatably connected to the fork 260 and the fixed frame 210 respectively. The fork 260 is rotated by the extension and retraction of the drive source. The fork 260 is provided with a transmission groove extending toward the rotation axis of the fork 260. The fixed frame 210 is provided with a guide groove 211 extending in the vertical direction. The end of the pressure roller 220 passes through the transmission groove and the guide groove 211. At this time, the rotary drive unit drives the shift fork 260 to rotate. When the shift fork 260 rotates upward, it drives the transmission shaft to move upward along the guide groove 211, thereby driving the pressure roller 220 to move upward and abut against the transition roller 270. When the rotary drive unit drives the shift fork 260 to rotate in the opposite direction, the shift fork 260 rotates downward, driving the transmission shaft to move downward along the guide groove 211, thereby driving the pressure roller 220 to move downward away from the transition roller 270. Naturally, the rotary drive unit can directly drive the shift fork 260 to rotate on the fixed frame 210, or it can drive the shift fork 260 to rotate on the fixed frame 210 by means of a lever.

[0036] In a lifting device that drives the fork 260 to rotate, thereby causing the pressure roller 220 to move up and down, such as Figure 4 and Figure 5 As shown, the fixing frame 210 is further provided with a straight groove 212 extending in the horizontal direction, and the guide grooves 211 are respectively provided at both ends of the straight groove 212. When the conveying device 100 moves the mold to below the pressure roller 220, the fork 260 rotates to drive the drive shaft upward into a guide groove 211 at one end of the straight groove 212. At this time, the pressure roller 220 is not in contact with the mesh fabric on the top surface of the mold. After the conveying device 100 moves the mold forward a certain distance, the fork 260 rotates to drive the drive shaft into the straight groove 212. At this time, the pressure roller 220 moves down to the middle of the mesh fabric and rolls forward from the middle of the mesh fabric, consistent with the direction of the template conveying. After passing the mesh fabric, it rises and leaves the mesh fabric. At this time, the fork 260 rotates to drive the drive shaft upward into the guide groove 211 at the other end of the straight groove 212. The template continues to move forward, and the fork 260 rotates in the opposite direction, causing the pressure roller 220 to fall back to the middle of the mesh fabric and roll backward. After passing the mesh fabric, it rises and leaves the mesh fabric. At this time, the pressure roller 220 contacts the upper transition roller 270, which can remove glue from the pressure roller 220. In this way, the pressure roller 220 will not contact the end of the mesh in the forward direction when rolling the mesh, thereby effectively reducing the phenomenon of the pressure roller 220 adhering and lifting the mesh, and further improving the rolling effect on the mesh.

[0037] To reduce the likelihood of increased viscosity due to glue drying on the transition roller 270, in this embodiment, the fixing frame 210 is provided with a connecting pipe 300, on which multiple atomizing nozzles are arranged facing the transition roller 270. The connecting pipe 300 can be connected to an external water supply pipe or water supply device, allowing external water to be supplied to the multiple atomizing nozzles. Alternatively, an external humidifier can supply humidifying mist to the connecting pipe 300, from which the multiple atomizing nozzles spray water mist onto the transition roller 270. This water mist then flows down to the pressure roller 220 during the glue removal process, thereby wetting the transition roller 270 and the pressure roller 220, delaying the excessive viscosity or hardening of the glue during drying.

[0038] When the adhesive is recycled into the recycling tank 240, to facilitate its removal, in this embodiment, the recycling tank 240 is provided with an inlet at one end and a drain at the other end. An external water supply device can be connected to the inlet, while the drain is connected to an external collection container. During operation, the water supply device supplies a small amount of water to the inlet, which promotes the flow of the adhesive in the recycling tank 240, thereby draining the adhesive to the drain, effectively preventing the adhesive from hardening and becoming difficult to clean in the recycling tank 240.

[0039] To further improve the rolling effect of the pressure roller 220 on the mesh fabric, in this embodiment, a sponge layer is provided on the outer periphery of the pressure roller 220. The sponge layer is soft, allowing for more thorough contact with the mesh fabric during rolling and providing sufficient downward pressure, thereby improving the rolling effect. Furthermore, it prevents the mosaic pieces on the mold from shifting due to excessive downward pressure, thus avoiding any impact on the rolling effect.

[0040] A screen pasting machine includes the aforementioned rolling mechanism.

[0041] In this screen bonding machine, the aforementioned rolling mechanism is used to further roll the laid screen fabric. Since the rolling mechanism can remove the glue on the surface of the pressure roller 220 in a timely manner, it reduces the stickiness of the pressure roller 220 surface after rolling, effectively preventing the pressure roller 220 from sticking the screen fabric or causing the screen fabric to shift when rolling it, thereby improving the rolling effect of the screen fabric and the final product quality.

[0042] The screen coating machine includes a frame, on which a guiding assembly, an unwinding mechanism, a cutting mechanism, and an adhesive applicator are mounted. The guiding assembly has a downwardly inclined guide gap. The guiding assembly can be two plates mounted on the frame, each extending downwards at an angle, forming a guide gap between them. To facilitate the feeding of the screen roll into the guide gap, the two plates are inclined away from each other at their top positions, forming an enlarged opening. The unwinding mechanism has a rotatable unwinding roller, which unwinds the screen into the guide gap. The cutting mechanism has a cutter that reciprocates below the guide gap. The adhesive applicator is located below the cutting mechanism, and within the adhesive applicator, a rotatable upper... The upper and lower glue-coating rollers are used to apply glue to the passing wire mesh roll. Naturally, the frame is equipped with a motor that can drive the upper and lower glue-coating rollers to rotate. The motor can drive the upper and lower glue-coating rollers to rotate synchronously through gear transmission. There are various ways to apply glue to the upper and lower glue-coating rollers. For example, multiple glue spraying heads are set on the frame directly opposite the upper or lower glue-coating roller. Multiple glue spraying heads simultaneously spray glue onto the upper or lower glue-coating roller. At this time, a glue layer is formed on the outer layer of the upper or lower glue-coating roller. When the wire mesh roll passes between the upper and lower glue-coating rollers, the glue can be applied to the wire mesh roll. The rolling mechanism is located downstream of the conveying device 100 relative to the glue-coating mechanism.

[0043] As described above, the mesh roll for applying the mesh is loaded onto the unwinding roller, and one end of the mesh roll is fed through the guide gap. The guide gap guides and limits the mesh roll, releasing it between the upper and lower gluing rollers. After the mesh roll has been released to the required length, the cutter in the cutting mechanism moves horizontally below the guide gap to cut the mesh roll located between the guide gap and the gluing mechanism. Then, the upper and lower gluing rollers continue to rotate, feeding the cut mesh roll downwards while simultaneously applying glue to it. At this time, the mosaic sheet to be meshed passes under the lower gluing roller, allowing the released mesh roll to be directly laid on the mosaic sheet. Then, it passes through the pressure roller 220, which further presses the mesh roll onto the mosaic sheet.
