Description

Technical Field

[0001] The utility model belongs to the technical field of tile laying tools, and in particular relates to an electric tile laying machine. Background Art

[0002] At present, there is a paving machine for laying ceramic tiles, floor tiles, etc. on the market. When in use, the suction cup is deformed to generate negative pressure to adsorb the column tiles. The paving machines in the prior art are all manually controlled by a joystick connected to the suction cup to deform the suction cup to generate negative pressure, so that it is adsorbed on the tile. During the operation of this paving machine, the user needs to hold the joystick all the time until the laying is completed, and then release the joystick. This method of manually pulling the joystick to make the suction cup adsorb the tile is prone to the problem that the suction cup cannot firmly adsorb the tile if the user does not pull it into place, and it will also cause arm pain to the user during the operation. Utility Model Content

[0003] The utility model provides an electric tile laying machine, aiming to solve the problem that the tile laying machine in the prior art uses a manual lever to make a suction cup absorb tiles, which is easy to cause the suction cup to fail to absorb the tiles firmly because the user fails to pull the lever into place.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] An electric paving machine, comprising:

[0006] Body;

[0007] A suction cup is arranged on the body, and a suction surface is arranged on the lower side of the suction cup;

[0008] A swing rod, one end of which is provided with a support end supported on the machine body, and the other end of which is provided with a power input end, the middle part of the swing rod is connected to the upper side of the suction cup, and the power input end includes a first position located at a high position and a second position located at a low position; and

[0009] A driving assembly is arranged on the machine body and is used to drive the power input end; when the driving assembly drives the power input end to rise to the first position, the swing rod is lifted upward with the supporting end as a fulcrum and drives the suction cup to generate negative pressure on the suction surface of the suction cup;

[0010] When the driving assembly drives the power input end to descend to the second position, the swing rod descends with the supporting end as a fulcrum and releases the negative pressure of the suction cup.

[0011] A further solution: the driving assembly includes a turntable and a turntable motor for driving the turntable to rotate, a guide rail is arranged around the turntable, and the lower side of the power input end abuts against the upper side of the guide rail; a recessed portion and a protruding portion are arranged on the guide rail, and the recessed portion and the protruding portion have a smooth transition;

[0012] When the turntable rotates to make the protrusion abut against the power input end, the power input end is located at the first position; when the turntable rotates to make the recess abut against the power input end, the power input end is located at the second position.

[0013] Based on the above technical solution: the turntable motor drives the turntable to rotate, so that the recessed part and the protruding part of the turntable cooperate with the power input end respectively, and then the power input end switches between the first position and the second position, so that in the first position, the swing rod drives the suction cup to deform and adsorb the tile, and in the second position, the suction cup releases the adsorption of the tile. The electric operation is simple and labor-saving, and has a high safety factor.

[0014] A further solution: a micro switch is provided in the body, the micro switch is located on the upper side of the power input end and is electrically connected to the turntable motor; when the turntable motor drives the turntable to rotate until the protrusion abuts against the power input end, the power input end triggers the micro switch to stop the turntable motor, and the protrusion remains abutted against the power input end.

[0015] Based on the above technical solution: by setting a micro switch, when the turntable rotates to make the protrusion abut against the power input end, the power input end triggers the micro switch, thereby stopping the turntable motor. At this time, the protrusion remains in a state of abutting against the power input end, so that the power input end remains in the first position, thereby keeping the suction cup in a state of adsorbing the tile, which is safer.

[0016] A further solution: the guide rail is located on the upper surface of the turntable.

[0017] A further solution: the drive assembly further includes a return spring located between the suction cup and the body.

[0018] Based on the above technical solution: when the swing arm drives the suction cup to rise, the reset spring is compressed. When the swing arm descends, the suction cup resets under the action of the reset spring to release the adsorption of the tile. The reset spring makes the suction cup more sensitive.

[0019] A further solution: there are two protruding parts and two recessed parts respectively, and the two protruding parts and the two recessed parts are arranged alternately around the guide rail.

[0020] A further solution: the driving assembly includes a driving motor, an eccentric wheel arranged at the output end of the driving motor, and a cam, the upper end of the cam is sleeved on the eccentric wheel, the lower end of the cam is provided with a through hole, and the power input end is located in the through hole; the driving motor drives the eccentric wheel to rotate to make the through hole rise or fall and switch the power input end between the first position and the second position.

[0021] A further solution: a mounting seat is provided on the lower side of the body, and the suction cup is arranged on the lower side of the mounting seat; a connecting rod is provided between the upper side of the suction cup and the swing rod, the upper end of the connecting rod passes through the mounting seat and is hinged to the swing rod, and the lower end of the connecting rod is fixedly connected to the center of the suction cup.

[0022] Based on the above technical solution: the upper end of the connecting rod is hinged to the swing rod, and the lower end is fixedly connected to the center of the suction cup, so that the connecting rod drives the middle of the suction cup to lift it upward perpendicular to the suction cup, so that the space between the suction cup and the tile becomes larger to generate negative pressure, so that the suction cup can be more stably and firmly adsorbed on the tile, facilitating the laying of the tile.

[0023] A further solution: a metal protrusion is provided on the mounting seat, and the supporting end abuts against the metal protrusion.

[0024] Based on the above technical solution: since the support end needs to be used as a fulcrum to bear force, in order to prevent the mounting seat from being compressed and deformed, a metal protrusion that cooperates with the support end is provided on the mounting seat to prevent the support end from being compressed and deformed.

[0025] A further solution: both left and right sides of the swing rod are provided with limit assemblies, and the limit assemblies are arranged on the mounting seat.

[0026] Based on the above technical solution: the limit components located on the left and right sides of the swing rod can prevent the swing rod from swinging left and right, so that the power input end of the swing rod is more stable when rising or falling, so that when the power input end is in the first position, the suction cup can more stably adsorb the tiles.

[0027] A further solution: a vibration assembly is provided on the mounting seat; the vibration assembly includes a vibration motor and two eccentric blocks, and the two eccentric blocks are respectively arranged on the output shaft on both sides of the vibration motor; two mounting grooves are provided on the mounting seat, and the two eccentric blocks are respectively located in the two mounting grooves; the swing rod is located between the two eccentric blocks.

[0028] Based on the above technical solution: by setting a vibration motor and two eccentric blocks, and the two eccentric blocks are respectively set at the output ends on both sides of the vibration motor, a balancing effect is played, and uniform vibration can be generated when laying tiles, so that the laying is smoother.

[0029] The beneficial effects of the utility model are:

[0030] The utility model sets one end of a swing arm as a supporting end and the other end as a power input end, the middle part of the swing arm is connected to the upper side of the suction cup, and the swing arm drives the suction cup through the lever principle under the action of a driving component, so that the swing arm, driven by the driving component, rises with the supporting end as a fulcrum, thereby driving the suction cup to rise and generate negative pressure to adsorb on ceramic tiles and floor tiles, or descends with the supporting end as a fulcrum, so that the suction cup recovers its deformation and releases the negative pressure to release the adsorption of the ceramic tiles; the suction cup is controlled by the electric driving component, thereby avoiding the problem of loose adsorption due to manual failure to pull it into place, and the operation is more labor-saving.

[0043] When the driving assembly drives the power input end 21 to descend to the second position, the swing arm 2 descends with the supporting end 22 as a fulcrum and releases the negative pressure of the suction cup 12, thereby releasing the adsorption effect on the tile. In this embodiment, the driving assembly is electrically driven.

[0044] In this embodiment, Figure 1 and Figure 2 As shown, a mounting seat 11 is provided at the lower side of the machine body 1, the mounting seat 11 is fixedly connected to the machine body 1, and the suction cup 12 is arranged at the lower side of the mounting seat 11; a connecting rod 3 is provided between the upper side of the suction cup 12 and the swing rod 2, the upper end of the connecting rod 3 passes through the mounting seat 11 and is hinged to the swing rod 2, and the lower end of the connecting rod 3 is fixedly connected to the center of the suction cup 12.

[0046] When the turntable 5 rotates to make the protrusion 512 abut against the power input end 21, the power input end 21 is located in the first position, at which time the swing arm 2 rises upward with the support end 22 as a fulcrum, thereby driving the suction cup 12 to deform and causing negative pressure to be generated on the adsorption surface of the suction cup 12; when the turntable 5 rotates to make the recessed portion 511 abut against the power input end 21, the power input end 21 is located in the second position, at which time the swing arm 2 descends, the suction cup 12 resumes its deformation, releases the negative pressure, and releases the adsorption of the tile.

[0047] The guide rail 51 is preferably arranged on the upper surface of the turntable 5, and the lower side of the power input end 21 abuts against the upper surface of the guide rail 51. Specifically, the protrusions 512 and the recesses 511 are preferably two each, and the two protrusions 512 and the two recesses 511 are arranged alternately around the guide rail 51.

[0048] When the swing arm 2 is lowered, in order to quickly restore the deformation of the suction cup 12, the driving assembly further includes a reset spring located between the suction cup 12 and the body 1. When the swing arm 2 drives the suction cup 12 to rise, the reset spring is compressed.

[0050] In this embodiment, Figure 1 and Figure 2As shown, as a specific structure of the swing arm 2, the swing arm 2 is integrally formed, and includes a first arm 23 located at the upper side, a second arm 24 located at the lower side and parallel to the first arm 23, and a third arm 25 connecting the first arm 23 and the second arm 24 and tilted upward from the center of the mounting seat 11, the first arm 23 and the second arm 24 are respectively located on opposite sides of the third arm 25; the power input end 21 is located on the first arm 23, and the support end 22 is formed by bending the free end of the second arm 24 downward. The third arm 25 extends from the center of the suction cup 12 to the outer side away from the center of the suction cup 12.

[0051] In order to prevent the support end 22 from deforming the mounting seat 11, a metal protrusion 112 is provided on the mounting seat 11 in this embodiment, and the support end 22 abuts against the metal protrusion 112. Specifically, the metal protrusion 112 can be a bolt, which is fixed on the mounting seat 11, and the support end 22 abuts against the bolt head.

[0052] In this embodiment, in order to prevent the swinging rod 2 from swinging left and right, which may cause the suction cup 12 to not be firmly adsorbed when adsorbing tiles, a limit assembly 113 is provided on both the left and right sides of the swinging rod 2, and the limit assembly 113 is arranged on the mounting seat 11.

Specifically, when the driving motor rotates, the eccentric action of the eccentric wheel will drive the cam to move up and down, so that the cam drives the power input end 21 to move up and down.

[0055] In this embodiment, the driving assembly may also be other structures such as a gear rack in the prior art.

[0056] Working principle description:

[0057] The swing arm 2 drives the suction cup 12 through the lever principle under the action of the driving component. When the driving component drives the power input end 21 to rise to the first position, the swing arm 2 is lifted upward with the support end 22 as a fulcrum and drives the suction cup 12 to generate negative pressure on the suction surface of the suction cup 12, thereby adsorbing on the ceramic tile or floor tile.

[0058] When the driving assembly drives the power input end 21 to descend to the second position, the swing arm 2 descends with the supporting end 22 as a fulcrum and releases the negative pressure of the suction cup 12, thereby releasing the adsorption effect on the tile.

[0059] The present utility model is not limited to the above optional implementation modes. Under the premise of not conflicting with each other, the various schemes can be combined arbitrarily. Anyone can derive other forms of products under the inspiration of the present utility model.
