Description

Automatic gluing machine for wall joints of prefabricated buildings

Technical Field

The invention belongs to the field of wall joint glue-applying machines, and particularly relates to an automatic glue-applying machine for wall joints of fabricated buildings.

Background

Buildings assembled from prefabricated parts at the site are called fabricated buildings.

Compared with the traditional building, a large number of building parts in the fabricated building are produced and processed in a workshop, and a large number of assembly operations on site are greatly reduced compared with the original cast-in-place operation. The assembly type building adopts building and decoration integrated design and construction, and ideally, decoration can be synchronously carried out along with main body construction, and the assembly type building is energy-saving and environment-friendly.

However, the assembled building has a large number of vertical or horizontal wall seams due to the assembly form, and a glue applicator is needed for gluing and blocking the wall seams. When the traditional wall joint glue spreader is under the action of external force, the lateral movement or the swing can occur, so that the working glue spreader can not continue to effectively spread the wall joint. Therefore, it is necessary to design an automatic glue applicator for wall joints of fabricated buildings to solve the above problems.

The invention designs an automatic gluing machine for wall joints of fabricated buildings, which solves the problems.

At the moment, the telescopic rod B on one side of the further tightened synchronous belt part contracts under the action of the tightened synchronous belt, so that the tightened synchronous belt part becomes loose, the tightened synchronous belt drives the belt pulley B to rotate in an accelerating mode to be effectively weakened, the belt pulley B drives the reverse sliding speed of the sliding seat relative to the base through a series of transmissions to be basically the same as the movement speed of the base relative to the ground, and further the reverse sliding speed of the driving wheel driving the sliding seat through a series of transmissions is still basically equal to the movement speed of the base relative to the ground when the driving wheel passes through the ground protruding part, and further the glue gun is guaranteed to be small in moving distance in the horizontal direction and still carry out effective gluing on vertical or horizontal wall seams.

As a further improvement of the technology, a trapezoidal guide block A is arranged at the bottom of the sliding seat and slides in a trapezoidal guide groove A on the base; the lower end of the vertical rod is provided with a trapezoidal guide block B which slides in a trapezoidal guide groove B on the swing seat; two guide blocks C are symmetrically arranged on the sliding block B and respectively slide in the two guide grooves C on the inner wall of the sliding groove. The cooperation of the trapezoidal guide block A and the trapezoidal guide groove A plays a role in positioning and guiding the sliding of the sliding seat on the base. The trapezoidal guide block B is matched with the trapezoidal guide groove B to play a role in positioning and guiding the sliding of the vertical rod on the swinging seat. The guide block C is matched with the guide groove C to play a positioning and guiding role in the sliding of the sliding block B in the sliding groove.

As a further improvement of the technology, the telescopic rod A consists of an inner rod A and an outer sleeve A; the inner rod A is symmetrically provided with two guide blocks A which slide in two guide grooves A on the inner wall of the outer sleeve A respectively; the spring B is positioned in the outer sleeve A; one end of the spring B is connected with the inner wall of the outer sleeve A, and the other end of the spring B is connected with the tail end of the inner rod A; the spring B is an extension spring; the telescopic rod B consists of an inner rod B and an outer sleeve B; the inner rod B is symmetrically provided with two guide blocks B which slide in two guide grooves B on the inner wall of the outer sleeve B respectively; the spring C is positioned in the outer sleeve B; one end of the spring C is connected with the inner wall of the outer sleeve B, and the other end of the spring C is connected with the end face of the inner rod B; the spring C is a compression spring; one end of the spring A is connected with the inner wall of the guide seat, and the other end of the spring A is connected with the upper end face of the sliding block A; one end of the spring D is connected with the inner wall of the sliding chute, and the other end of the spring D is connected with the sliding block B; and one end of the spring E is connected with the side surface of the sliding seat, and the other end of the spring E is connected with a fixed block arranged on the same side of the base. The guide block A is matched with the guide groove A to play a positioning and guiding role in the sliding of the inner rod A relative to the outer sleeve A, and the inner rod A is prevented from being separated from the outer sleeve A under the pulling of the synchronous belt. The guide block B is matched with the guide groove B to play a positioning and guiding role in the sliding of the inner rod B in the outer sleeve B, so that the inner rod B is prevented from being separated from the outer sleeve B.

As a further improvement of the technology, the pedal rod vertically slides in a movable groove A which is arranged on the side wall of the base and communicated with the transmission groove A and a movable groove C arranged on the side wall of the guide seat; one ends of the two swing rods are hinged in the swing grooves at the lower ends of the sliding blocks A; the two swing rods swing in the two movable grooves B on the two sides of the guide seat around the hinged point with the slide block A respectively.

As a further improvement of the technology, a gear A is arranged on a shaft where the belt wheel B is arranged, and the gear A is positioned in a transmission groove C on the upper end surface of the base; the gear A is meshed with a gear B arranged in the transmission groove C, and the gear B is meshed with a rack arranged at the bottom of the sliding seat.

As a further improvement of the present technology, the transmission ratio of the pulley a to the pulley B is 1: 1; the pitch circle diameter of gear a is equal to the diameter of the drive wheel. When the base laterally moves along the direction parallel to the wall surface under the action of external force, the belt wheels A arranged on the shafts of the two driving wheels drive the belt wheels B to rotate through the synchronous belt. Because the transmission ratio of the belt pulley A to the belt pulley B is 1: 1; the reference circle diameter of the gear A is equal to the diameter of the driving wheel, so the rotating speed of the gear A coaxial with the belt wheel B is equal to the rotating speed of the driving wheel, and the linear speed of the gear A driving the sliding seat to slide relative to the base through the gear B and the rack is equal to the linear speed of the base relative to the ground and opposite to the linear speed. The moving speed of the slide seat relative to the base is equal to the moving speed of the base relative to the ground, so that the glue gun installed on the vertical rod does not move relative to the ground or the wall in the horizontal direction, the glue gun which is used for gluing the wall seam in the process of acting on the base by external force parallel to the wall is guaranteed not to move in the horizontal direction, the glue gun which is working is driven by the sliding sleeve to continuously perform normal gluing work on the vertical or horizontal wall seam along the vertical direction, and the efficiency of gluing the wall seam is improved.

Compared with the traditional wall seam gluing machine, when the base laterally moves in the direction parallel to the wall surface under the action of external force, the two driving wheels drive the sliding seat to move in the opposite direction relative to the base through a series of transmission, and the moving speed of the sliding seat relative to the base is equal to that of the base relative to the ground, so that the glue gun arranged on the vertical rod does not move in the horizontal direction relative to the ground or the wall surface, the glue gun which is gluing the wall seam in the process of acting on the base by the external force parallel to the wall surface does not move in the horizontal direction, the glue gun which is working continuously performs normal gluing work on the vertical or horizontal wall seam in the vertical direction under the driving of the sliding sleeve, and the efficiency of gluing the wall seam is improved.

Meanwhile, when the base is under the action of an external force parallel to the wall surface, one of the driving wheels passes through the raised part on the ground, the reverse sliding speed of the sliding seat relative to the base is basically kept the same as the movement speed of the base relative to the ground, and then the driving wheel is ensured to drive the reverse sliding speed of the sliding seat to be still basically equal to the movement speed of the base relative to the ground through a series of transmissions when passing through the raised part on the ground, so that the moving distance of the glue gun in the horizontal direction is ensured to be small, and the glue gun still carries out effective gluing on the vertical or horizontal wall joint.

When one end of the base swings away from the wall surface due to the action force applied to one corner of the base, the compressed spring D pushes the sliding block B to drive the L rod hinged with the sliding block B to swing towards the wall surface through the compressed plate spring B, meanwhile, the L rod drives the swinging seat to keep contact with the wall surface through the compressed plate spring C, and the sliding seat basically does not move relative to the wall surface, so that a glue gun which is gluing in a wall gap cannot move horizontally relative to the wall surface, the glue gun can still continuously perform vertical or horizontal gluing work on the wall gap on the wall surface when the base swings laterally, and the gluing efficiency is improved.

The invention has simple structure and better use effect.

The working process of the invention is as follows: in the initial state, the sliding seat 41 is located in the middle of the base 1, and the two springs E50 are in the tension energy storage state. The swinging seat 53 is retracted into the sliding seat 41, and the recovery rod 64 is inserted into the slot 46 on the sliding seat 41 to recover and keep the swinging seat 53 within the sliding seat 41. The spring D49 is in a compressed energy storage state and the L-bar 52 is in contact with the limit swing block 56. The plate spring B55 and the plate spring C57 are both in a compression energy storage state. The spring A16 is in the tension energy storage state, the slide block A14 is at the upper extreme position in the guide seat 11, and the pedal lever 40 is at the top of the movable groove A4 on the base 1. The two plate springs A19 are in a compression energy storage state, and under the action of the two plate springs A19, the two swing rods 17 respectively and simultaneously drive the two driving wheels 18 to be in contact with the ground. The telescopic rod A27 is in a stretching state, the two telescopic rods B33 are in a contracting state, and the synchronous belt 22 is in a tightening state. The gear is engaged with the middle of the rack 44. The two swing rods 17 are respectively spaced from the two fixing rods 20.

When the invention is used for gluing wall seams, the base 1 is tightly attached to the wall surface, so that the axis of the driving wheel 18 is vertical to the wall surface. The four screws 8 are adjusted so that the four screws 8 form a horizontal support for the support of the base 1. During the adjustment of the screw 8, the two swing rods 17 respectively drive the corresponding driving wheels 18 to keep constant contact with the ground under the action of the corresponding leaf springs a 19. Then the recovery rod 64 is pulled out, the sliding block B47 slides to the wall surface along the direction vertical to the wall surface under the action of the spring D49, the sliding block B47 drives the L rod 52 to swing to the wall surface direction through the plate spring B55 and separate from the swing limiting block 56, and the L rod 52 drives the swing seat 53 to be tightly attached to the wall surface through the plate spring C57.

Then, the driving module a60 and the driving module B63 are turned on to drive the glue gun 62 to glue the wall joint.

In the gluing process, if the side surface of the base 1 is acted by a force parallel to the wall surface, the base 1 can move on the ground parallel to the wall surface. The two driving wheels 18 rotate in the same direction under the action of the ground due to the movement of the base 1, the two rotating driving wheels 18 drive the two belt wheels A21 to rotate synchronously through the shafts, and the two belt wheels A21 drive the belt wheel B23, the supporting wheel A32 and the two supporting wheels B39 to rotate through the synchronous belt 22. The pulley B23 drives the gear A25 to synchronously rotate through the shaft on which the pulley B23 is arranged, the gear A25 drives the gear B26 to synchronously rotate through the shaft on which the gear B26 is arranged, the sliding seat 41 is driven by the gear B26 to horizontally slide on the base 1 relative to the base 1 along the direction parallel to the wall surface through the rack 44, the two springs E50 simultaneously generate deformation energy storage, one spring E50 is further stretched, and the other spring E50 is contracted. Since the transmission ratio of the pulley a21 to the pulley B23 is 1: 1, the reference circle diameter of the gear A25 is equal to the diameter of the driving wheel 18, so that the sliding speed of the sliding base 41 relative to the base 1 is equal to the moving speed of the base 1 relative to the ground and the direction is opposite, so that the sliding base 41 does not horizontally move relative to the wall surface, the glue gun 62 which is gluing the wall seam is ensured not to move in the horizontal direction in the process of acting the base 1 by external force parallel to the wall surface, the glue gun 62 which is working is driven by the sliding sleeve 61 to continuously glue the vertical or horizontal wall seam in the vertical direction, and the efficiency of gluing the wall seam is improved.

When the base 1 is subjected to an external force parallel to the wall surface so that one of the driving wheels 18 passes through the raised portion on the floor, the portion of the timing belt 22 between the driving wheel 18 passing through the raised portion and the adjacent driving wheel 18 becomes slack by the rotational speed of the driving wheel 18 passing through the raised portion being greater than the rotational speed of the other driving wheel 18, and the portion of the timing belt 22 between the driving wheel 18 passing through the raised portion and the pulley B23 becomes further tightened to thereby preliminarily accelerate the pulley B23. At this time, the telescopic rod B33 on the side of the further tightened synchronous belt 22 contracts under the action of the tightened synchronous belt 22, so that the tightened synchronous belt 22 becomes loose, the tightened synchronous belt 22 drives the belt pulley B23 to rotate in an accelerated manner to be effectively weakened, the belt pulley B23 drives the reverse sliding speed of the sliding seat 41 relative to the base 1 through a series of transmissions to be basically the same as the movement speed of the base 1 relative to the ground, and further, it is ensured that the reverse sliding speed of the driving slide seat 41 through a series of transmissions is still basically equal to the movement speed of the base 1 relative to the ground when one driving wheel 18 passes through a raised part of the ground, and further, the moving distance of the glue gun 62 in the horizontal direction is small, and the glue is still effectively applied to vertical or horizontal wall joints.

When one end of the base 1 swings away from the wall surface due to the action force applied to one corner of the base 1, the sliding block B47 pressed by the compressed spring D49 drives the L rod 52 hinged with the sliding block B47 to swing towards the wall surface through the compressed plate spring B55, meanwhile, the L rod 52 drives the swinging seat 53 to keep contact with the wall surface through the compressed plate spring C57, and the sliding seat 41 basically does not move relative to the wall surface, so that the glue gun 62 which is gluing the wall seam cannot move horizontally relative to the wall surface, the glue gun 62 can still continuously perform vertical or horizontal gluing work on the wall seam on the wall surface when the base 1 swings sideways, and the gluing efficiency is improved.

When the invention is finished or when the application of glue is a paragraph, the slide 41 is repositioned relative to the base 1. The foot is used for stepping on the pedal lever 40 downwards, the pedal lever 40 drives the sliding block A14 to synchronously vertically move downwards in the guide seat 11, and the sliding block A14 drives the spring A16 to further stretch and store energy. The slide block a14 drives the two swing rods 17 to contact with the two fixing rods 20 and swing upwards around the hinge point under the prevention of the two fixing rods 20, and the two swing rods 17 respectively drive the two driving wheels 18 to separate from the ground. Under the reset action of two springs E50, slide 41 resets for base 1, and slide 41 drives gear B26 through rack 44 and counter-rotates, and gear B26 drives through gear A25 and counter-rotates through its axis pulley B23 that is located, and pulley B23 drives two pulleys A21, supporting wheel A32 and two supporting wheels B39 through hold-in range 22 and counter-rotates, and the effort that acts on pedal lever 40 is withdrawn to slide 41 for the complete reset of base 1. Under the reset action of the spring A16, the slide block A14 is reset vertically and upwards, the two swing rods 17 are respectively reset in a swinging mode under the action of the corresponding plate spring A19, finally the two swing rods 17 drive the two driving wheels 18 to be in contact with the ground again, and finally the two swing rods 17 are separated from the two fixing rods 20.

After the sliding seat 41 is reset relative to the base 1, the swinging seat 53 is retracted into the range of the sliding seat 41 by hand, the swinging seat 53 drives the L rod 52 to swing back and retract around a hinge point with the sliding block B47 through the plate spring C57, the L rod 52 drives the sliding block B47 to move in the sliding groove 42 along the direction perpendicular to the wall surface and far away from the wall surface through the plate spring B55, and the spring D49 is compressed and stored with energy again. When the L-bar 52 comes back into contact with the rocker 56, the slider B47 continues to move relative to the base 1 under the continued pushing of the L-bar 52. When the swing seat 53 swings into the range of the slot 46 again, the recovery rod 64 is inserted into the slot 46 and the recovery state of the swing seat 53 is fixed.

In conclusion, the beneficial effects of the invention are as follows: when the base 1 moves along the direction parallel to the wall surface under the action of external force, the two driving wheels 18 drive the sliding seat 41 to move in the opposite direction relative to the base 1 through a series of transmission, and the moving speed of the sliding seat 41 relative to the base 1 is equal to that of the base 1 relative to the ground, so that the glue gun 62 mounted on the upright rod 58 does not move relative to the ground or the wall surface in the horizontal direction, and therefore the glue gun 62 which is gluing the wall gap is not moved in the horizontal direction in the process of acting on the base 1 by the external force parallel to the wall surface, the glue gun 62 which is working is driven by the sliding sleeve 61 to continuously carry out normal gluing work on the vertical or horizontal wall gap along the vertical direction, and the efficiency of gluing the wall gap is improved.

Meanwhile, when the base 1 is under the action of an external force parallel to the wall surface, one of the driving wheels 18 passes through the raised part on the ground, the reverse sliding speed of the sliding seat 41 relative to the base 1 is basically the same as the movement speed of the base 1 relative to the ground, so that it is ensured that the reverse sliding speed of the sliding seat 41 driven by a series of transmission when one driving wheel 18 passes through the raised part on the ground is still basically equal to the movement speed of the base 1 relative to the ground, and further that the moving distance of the glue gun 62 in the horizontal direction is small and the vertical or horizontal wall joint is still effectively glued.
