Description

Technical Field

[0001] This utility model belongs to the technical field of paving machines, and specifically relates to a paving machine. Background Technology

[0002] A tile laying machine is a device used for laying tiles and other similar items. It generally consists of a main body and suction cups mounted on the main body. An air pump is installed inside the main body, and a sealed cavity is formed between the suction cups and the main body. The air pump is connected to this cavity. When the suction cups come into contact with the tiles, the air pump draws air out of the cavity, creating negative pressure, which in turn causes the suction cups to adhere to the tiles.

[0003] This type of paving machine can only pick up smooth-surfaced tiles. When the tile is rough, that is, the tile surface is not smooth, the suction cup cannot seal well with the tile because the tile surface is not smooth enough, so the suction cup cannot effectively pick up the tile. When the paving machine picks up the tile, the tile is easy to fall off. Utility Model Content

[0004] This invention provides a tiling machine, which aims to solve the problem that existing tiling machines cannot pick up tiles with rough surfaces.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A paving machine includes a machine body and an elastic sealing ring disposed at the lower end of the machine body;

[0007] The area surrounded by the elastic sealing ring is a negative pressure zone. An air pump is installed inside the machine body. The air pump maintains the negative pressure zone in a negative pressure state by drawing air from the negative pressure zone.

[0008] A further improvement: The machine body is also equipped with a pressure sensor to detect the air pressure value in the negative pressure zone.

[0009] Based on the above technical solution: During the tile adsorption process, if air enters the negative pressure zone through gaps due to uneven tile surfaces or loose adhesion between the elastic sealing ring and the tile, the air pressure sensor can quickly detect the change in air pressure. The control system will immediately instruct the air pump to increase the suction force, restoring the negative pressure state in the negative pressure zone and preventing the tile from falling due to unstable adsorption, thus ensuring operational safety. Under different working environments and conditions, such as changes in temperature and humidity, the density and flow of air will affect the air pressure in the negative pressure zone. The air pressure sensor can sense these changes in real time and feed them back to the control system, enabling the paving machine to automatically adjust the adsorption parameters according to the actual working conditions, maintaining a stable adsorption effect and reliably adsorbing tiles in both dry indoor and humid outdoor environments.

[0010] A further improvement: The machine body is also provided with a support ridge for positioning the item adsorbed by the negative pressure zone, and the support ridge is located within the negative pressure zone.

[0011] Based on the above technical solution, the support ridges provide additional physical support for the adsorbed items. When the tile is adsorbed within the negative pressure zone, the support ridges limit the tile's position relative to the machine body, preventing excessive deformation of the elastic sealing ring. This effectively ensures the tile won't easily fall off, further enhancing the stability of the adsorption process.

[0012] A further improved solution: There are two support ridges with a gap between them, and the support ridges are in surface contact with the items adsorbed by the negative pressure zone.

[0013] Based on the above technical solution: the surface contact method increases the contact area between the supporting ridges and the adsorbed item. Compared with point contact or line contact, surface contact provides more stable support and fixation. The two supporting ridges support the item from different positions, further dispersing the force on the item and reducing the possibility of the item shaking or falling off due to gravity or external forces, making the item more stable during adsorption and movement.

[0014] A further improved solution: The negative pressure zone includes a first end and a second end opposite to the first end. An air extraction port is provided on the body, and the air extraction port communicates with the negative pressure zone. The air extraction port is located at the first end. The air pump draws air from the negative pressure zone through the air extraction port, and the air pressure sensor is located at the second end.

[0015] Based on the above technical solution: The air extraction port is positioned at the first end of the negative pressure zone. When the air pump draws air from the negative pressure zone through it, the air flows from all directions towards the first end. Because the extraction port is clearly positioned, air can be extracted relatively smoothly, allowing a stable negative pressure environment to be quickly established within the negative pressure zone. This layout contributes to the uniform distribution of negative pressure within the zone. The air flowing from all parts of the negative pressure zone towards the extraction port at the first end creates a relatively stable pressure gradient throughout the entire negative pressure zone, making the negative pressure values ​​at various points within the zone relatively similar. This ensures that the adsorbed item experiences a more uniform adsorption force throughout the entire negative pressure zone, avoiding unstable adsorption due to excessive localized negative pressure differences, and guaranteeing the reliability of the adsorption process.

[0016] A further improvement: The machine body is also provided with a groove for installing the air pressure sensor, and the air pressure sensor is threaded into the groove.

[0017] Based on the above technical solution: the groove provides a clear installation position for the pressure sensor. During assembly, operators can quickly and accurately place the pressure sensor into the groove, avoiding deviations in sensor installation position. The threaded connection secures the pressure sensor in the groove, providing strong and stable fixing force. The threaded connection is self-locking; even under vibration, impact, or other external forces during equipment operation, the pressure sensor is not easily loosened or detached. Compared to simple snap-fit ​​or adhesive fixing methods, the threaded connection better ensures long-term stable sensor operation, reducing measurement errors or equipment malfunctions caused by sensor loosening.

[0018] A further improvement: The body is also equipped with a handle, which is provided on the body by a buffer component to reduce the vibration of the handle.

[0019] Based on the above technical solution: During equipment operation, the machine body may vibrate due to internal mechanical movements, air pump operation, and other factors. If the handle is directly fixed to the machine body, these vibrations will be transmitted to the operator's hands without any attenuation. The buffer component acts like a "shock absorber," absorbing and dispersing some of the vibration energy, greatly reducing the vibration transmitted to the operator's hands. For example, when the paving machine is picking up and moving items, the machine body vibrates significantly, but with the buffer component on the handle, the operator will not experience excessive numbness or fatigue in their hands even after holding it for a long time, thus improving the comfort and endurance of operation.

[0020] A further improved solution: The buffer assembly includes a bellows, one end of which is fixed to the handle, and the other end of which is fixed to the body.

[0021] Based on the above technical solution: the bellows has a unique corrugated structure, which gives it excellent elasticity and flexibility. When the machine vibrates, the bellows can absorb and disperse the vibration energy through its own expansion and contraction and deformation. Under vibration, the bellows continuously compress and expand, converting the vibration energy into its own elastic potential energy, thereby greatly reducing the vibration transmitted to the handle and significantly reducing the vibration felt by the operator when holding the handle. In actual operation, the vibration of the machine may come from multiple directions, not just a single direction. The flexibility of the bellows allows it to adapt to vibrations in different directions. Whether it is up-and-down bumps, left-and-right swaying, or front-and-back impacts, the bellows can buffer these vibrations through corresponding deformation, providing all-round shock absorption protection for the handle and ensuring that the operator can obtain a relatively stable grip experience in various working scenarios.

[0022] A further improved solution: The buffer assembly includes a spring, one end of which is fixed to the handle, and the other end of which is fixed to the body.

[0023] Based on the above technical solution: Springs possess significant elastic properties. When the machine vibrates due to internal mechanical operation, external impact, or other factors, the spring deforms, converting the kinetic energy generated by the vibration into its own elastic potential energy. By continuously expanding and contracting to absorb and release energy, it effectively reduces the vibration transmitted to the handle, making it more comfortable for the operator to hold. The frequency of machine vibration varies in different working scenarios. Springs have a certain buffering capacity for vibrations of different frequencies. For low-frequency, large-amplitude vibrations, springs can absorb energy through larger deformations; for high-frequency, small-amplitude vibrations, springs can dissipate energy through rapid expansion and contraction.

[0024] A further improved solution: The machine body is equipped with a vibration motor, which includes a machine body and an output shaft mounted on the machine body. The output shaft is rotatably connected to the machine body, and both ends of the output shaft extend out of the machine body. Eccentric blocks for generating vibration are provided at both ends of the output shaft.

[0025] Based on the above technical solution: when the vibratory motor is powered on, the output shaft begins to rotate. Since the center of gravity of the eccentric block is not on the axis of the output shaft, the eccentric block will generate centrifugal force during rotation. This centrifugal force changes direction and magnitude continuously with the rotation of the output shaft, thus forming periodic vibration.

[0026] A further improved solution: the elastic sealing ring is bonded to the machine body, and the elastic sealing ring is in surface contact with the item adsorbed by the negative pressure area.

[0027] Based on the above technical solution: surface contact provides a larger contact area compared to point or line contact. The elastic sealing ring itself is elastic, allowing it to better conform to uneven surfaces of items adsorbed by the negative pressure zone. The surfaces of items adsorbed by the negative pressure zone may have various shapes and roughnesses. The surface contact characteristics of the elastic sealing ring allow it to adapt to these variations. For example, when the adsorption surface has tiny protrusions or depressions, the elastic sealing ring can fill these unevennesses through its own elastic deformation, maintaining a good seal. This expands the applicability of the device, enabling stable adsorption of more items of different shapes.

[0028] The beneficial effects of this utility model are as follows:

[0029] This invention, through the combination of an elastic sealing ring and a negative pressure zone, can adapt to tile surfaces of varying roughness, effectively adsorbing both smooth and rough tiles, greatly expanding the applicability of the tile laying machine. Even if there is a gap between the tile and the elastic sealing ring, the negative pressure state within the negative pressure zone remains stable due to the continuous extraction action of the air pump. This prevents the tile from easily falling off due to tiny gaps during the adsorption process, improving the stability and reliability of the adsorption. Operators can work with greater confidence when laying tiles, reducing repetitive work and safety hazards caused by falling tiles.

[0030] Unlike traditional pavers, operators no longer need to rigorously screen and pre-treat the tile surface when using the improved pavers. Whether dealing with tiles of varying surface conditions or uneven surfaces encountered during operation, the pavers can be used directly for adsorption and laying, enhancing operational flexibility.

[0031] Because the tile paver can adapt to more types of tiles and has improved adhesion stability, operators do not need to frequently adjust the position and pressure of the paver during the laying process, nor do they need to interrupt work due to tiles falling. This greatly shortens the tile laying time, improves work efficiency, and reduces labor intensity. Attached Figure Description

There are two support ridges 4 with a gap between them, and the support ridges 4 are in surface contact with the items adsorbed by the negative pressure zone 3. The cross-sectional shape of the support ridges 4 can be rectangular, and the support ridges 4 can be an integral part of the body 1.

[0043] Specifically: The negative pressure zone 3 includes a first end and a second end opposite to the first end. An air extraction port 5 is provided on the body 1, communicating with the negative pressure zone 3. The air extraction port 5 is located at the first end, and the air pump draws air from the negative pressure zone 3 through the air extraction port 5. The air pressure sensor is located at the second end. The body 1 also has a groove 6 for mounting the air pressure sensor, which is threaded into the groove 6.

[0044] The device body 1 is further provided with a handle 7, which is attached to the body 1 via a buffer assembly to reduce vibration. The buffer assembly includes a bellows 8, one end of which is fixed to the handle 7, and the other end of which is fixed to the body 1. Alternatively, the buffer assembly includes a spring 9, one end of which is fixed to the handle 7, and the other end of which is fixed to the body 1. The bellows 8 can be fixed by adhesive bonding. The spring 9 can be fixed by screws. Both the bellows 8 and the spring 9 can be simultaneously installed between the handle 7 and the body 1.

[0045] Specifically: A vibration motor 10 is installed inside the machine body 1. The vibration motor 10 includes the machine body 1 and an output shaft mounted on the machine body 1. The output shaft is rotatably connected to the machine body 1, and both ends of the output shaft extend out of the machine body 1. Eccentric blocks 11 for generating vibration are provided at both ends of the output shaft. The vibration motor 10 can be fixed to the machine body 1 with screws. The eccentric blocks 11 can be an integral part of the output shaft.

[0046] Specifically: the elastic sealing ring 2 is adhered to the body 1, and the elastic sealing ring 2 is in surface contact with the item adsorbed by the negative pressure zone 3. A groove for installing the elastic sealing ring 2 can be provided on the body 1. The elastic sealing ring 2 is adhered to the groove, and a portion of the elastic sealing ring 2 protrudes from the groove to ensure proper contact between the elastic sealing ring 2 and the tile.

[0047] The working principle of this embodiment:

[0048] The elastic sealing ring 2 is located at the lower end of the machine body 1, enclosing a specific area, which is the negative pressure zone 3. When the paving machine prepares to pick up the tile, the elastic sealing ring 2 comes into contact with the tile surface. Due to its elasticity, the elastic sealing ring 2 can adapt to the shape of the tile surface, whether smooth or rough, and can fit it to a certain extent. The air pump inside the machine body 1 is connected to the negative pressure zone 3 through a pipe, which creates conditions for subsequent air extraction. After the air pump starts working, it will continuously extract air from the negative pressure zone 3. As air is continuously extracted, the air pressure in the negative pressure zone 3 gradually decreases, forming a negative pressure state. At this time, the external atmospheric pressure is relatively higher than the air pressure in the negative pressure zone 3, which will exert a downward pressure on the tile, attempting to press the tile into the negative pressure zone 3. The elastic sealing ring 2 plays a certain role in blocking and sealing, preventing a large amount of air from rapidly entering the negative pressure zone 3. In practical use, even if there is a gap between the tile and the elastic sealing ring 2, because the air pump continuously extracts air from the negative pressure zone 3, the volume of air entering the negative pressure zone 3 from the gap between the tile and the elastic sealing ring 2 is less than or equal to the volume of air extracted from the negative pressure zone 3 by the air pump. In other words, the speed at which the air pump extracts air can compensate for or even exceed the speed at which air enters from the gap, thus maintaining the negative pressure state within the negative pressure zone 3. In this way, the external atmospheric pressure will continue to exert downward pressure on the tile, effectively adhering it to the paving machine and preventing it from falling off.

[0049] This utility model is not limited to the above-mentioned optional embodiments. Under the premise of non-contradiction, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the guidance of this utility model.
