Technical Field

[0001] The invention relates to the technical field of tools used in building decoration engineering, and in particular to an automatic mortar laying device for ceramic tiles. Background Art

[0002] In the prior art, the plastering machine for plastering the back of ceramic tiles and floor tiles has three stages, the first is the brick preparation stage; the second is the plastering stage; and the third is the brick removal stage. All three stages require manual participation, which is labor-intensive. The existing auxiliary machinery has a low degree of automation, especially in the plastering process, it is easy to fail, and the adaptability to complex construction environments is not high. Summary of the invention

[0003] In order to overcome the above-mentioned shortcomings of the prior art, reduce manual participation, make brick preparation and brick removal more convenient, solve common machine failures during the plastering process, and improve the adaptability to complex construction environments, the present invention provides an automatic plastering machine.

[0004] The technical solution adopted by the present invention is: an automatic ash spreading machine, characterized in that it includes a frame 1, a conveying bed 2, guide piles 3, a guide fence 4, and an ash trough 5;

[0005] The frame 1 is a square frame, and a conveyor bed 2 is installed in the frame 1. The conveyor bed 2 is composed of a conveyor belt 201, a rotating shaft 202 and a motor 203 providing power;

[0006] A plurality of guide piles 3 are installed on both sides of the conveyor bed 2 and above the side of the frame 1, and a guide fence 4 is arranged behind the guide piles 3;

[0007] The guide piles 3 and guide fences 4 arranged on both sides are parallel to each other and consistent with the travel direction of the conveyor bed 2; wherein, the upper end of the guide piles 3 is inclined from the outside to the inside to 1 / 3 of the overall height, and a plurality of guide piles 3 form a spatial horizontal plane with a larger upper portion and a smaller lower portion; wherein, the upper opening is used as a brick receiving opening, and the size is larger to facilitate brick entry; the lower opening is small, so that the position of the bricks after entry can be restricted, so that each brick falls accurately on the conveyor bed;

[0008] The guide fences 4 are arranged on both sides of the rear of the space plane surrounded by the guide piles 3, and the spacing is preferably such that the bricks can pass through. When the bricks pass through, the orientation of the bricks is corrected so that the bricks are pushed forward in the direction of the guide fences 4, which provides favorable conditions for the next step of paving the bricks.

[0009] A mortar trough 5 is installed on the guide fences 4 on both sides. The mortar trough 5 is a hollow component with a large opening at the upper end and a small opening at the lower end and surrounded on all sides. The mortar is filled in the mortar trough 5 and falls from the bottom and is spread flat on the brick body. After the brick body passes under the mortar trough 5, it pauses at the other end of the frame 1 and waits to be taken away.

[0010] The connection mode between the ash trough and the guide fence 4 is set to a connecting rod connection. The guide fence 4 is a hollow part. An upper connecting hole 501 and a lower connecting hole 401 are respectively set on both ends of the ash trough 5 and the guide fence 4. A spring 402 is installed in the inner cavity of the guide fence 4. The spring 402 is in an unsaturated compression state. The connecting rod 403 passes through the upper connecting hole 501, the lower connecting hole 401, and the spring 402 in sequence, and connects the ash trough 5, the guide fence 4, and the spring 402 from top to bottom. The elastic force of the spring 402 presses the guide fence 4 and the ash trough 5 from bottom to top, and at the same time ensures that the ash trough 5 can be lifted upward within a specific stroke from the unsaturated compression state of the spring 402 to the compression limit;

[0011] During the paving process, when large particles are encountered in the mortar, the ash trough 5 is squeezed and lifted by the large particles, the connecting rod 403 is pulled up, and the spring 402 is squeezed by the guide fence 4. After the particles are discharged smoothly, under the action of the ash trough 5's own gravity and the elastic force of the spring 402, the connecting rod 403 pulls the ash trough 5 to return to its original state, thereby achieving the goal of automatically discharging large particles and avoiding the machine from being stuck.

[0012] Preferably, a push bar 204 is installed on the conveyor belt 201, and the push bar 204 pushes the brick body to move forward.

[0013] Preferably, in order to reduce the floor space occupied by the mortar laying machine when in use, a brick station is provided in the brick discharging direction of the mortar trough, and the brick station is a virtual plane composed of horizontal support rods 605 fixed on both sides of the front end of the frame 1 and a movable telescopic sub-frame 6, and the telescopic sub-frame 6 includes a track 601, a pulley 602, a telescopic frame 603, and a blocking plate 604; wherein the track 601 is installed at a position inside the frame 1 and outside the conveyor bed 2, the pulley 602 is installed on the track 601, and the telescopic frame 603 is provided below the track 601, and the telescopic frame 603 is clamped by the pulley 602, so that it slides horizontally back and forth below the track 601 along the direction of brick movement;

[0014] The brick station is a platform composed of horizontal support rods 605 fixed on both sides of the front end of the frame 1 and vertical support rods 606 on the front end crossbar of the telescopic frame 603. The vertical support rods 606 are installed with a blocking plate 604, and the height of the blocking plate 604 is preferably such that it can be supported by the brick body;

[0015] During the mortar laying process, after the front end of the brick body contacts the blocking plate 604, the brick body pushes the blocking plate 604 to push the telescopic frame 603 out. After the brick body has completely passed through the mortar laying groove 5, the front end of the brick body stops on the vertical support rod 606 of the brick station, and the rear end of the brick stops on the horizontal support rods 605 on both sides of the front end of the frame 1. When taking the brick, first lift the front end of the brick, retract the telescopic frame 603 into the frame 1, and then you can easily take the brick away. In this way, the purpose of reducing components, making the machine structure compact, convenient brick taking and easy machine installation is achieved.

[0016] Preferably, in order to meet the requirements for laying long bricks, a reel-in roller device 8 is installed on the guide fence 4 at a position close to the brick feeding side of the mortar trough 5, and the reel-in roller device 8 and the conveyor bed 2 are clamped up and down to push the brick body; the specific method is: it includes an outer bracket 801, an inner bracket 802, a roller 803, a rotating shaft 804, a tension spring 805, and a pusher and puller 806, both ends of the roller 803 are fixed to the inner bracket 802 through bearings, and the roller 803 is rotated by a motor. The rotating shaft 804 and the tension spring 805 are respectively arranged at the front and rear of the roller 803, the rotating shaft 804 hinges the inner bracket 802 at both ends of the outer bracket 801, and the tension spring 805 pulls the inner bracket 802 and the outer bracket 801, so that the inner bracket 802 is suspended inside the outer bracket 801, and a push-pull device 806 is installed on the inner side of the top of the outer bracket 801. When the push-pull device 806 is in motion, the suspended inner bracket 802 is squeezed downward, so that the inner bracket 802 rotates downward with the rotating shaft 804 as a fulcrum, driving the roller 803 to descend, forming a conveying mode of clamping the brick body with the conveyor bed 2 from top to bottom, and installing an induction switch 807 next to the roller 803. The induction switch 807 controls the push-pull device 806. When there are no bricks, the push-pull device 806 contracts, driving the inner bracket 802 and the roller 803 to rise and reset, and the brick inlet is opened. After sensing the brick body entering, the inner bracket 802 drives the roller 803 to descend and clamp the brick body.

[0017] Preferably, a shock absorber 9 is installed on the rotating shaft 804 of the roller device 8. The lower section of the shock absorber 9 is a semicircular ring 901, and the upper section is a support rod 902. A shock-absorbing spring 903 is sleeved on the support rod 902. First, a strip hole 904 is opened at the hinge position between the two ends of the outer bracket 801 and the rotating shaft 804, so that the rotating shaft 804 can move up and down. A slot 905 is installed above the strip hole 904. The semicircular ring 901 is buckled on the rotating shaft 804, and the support rod 902 is installed in the slot 905 and can move up and down. The two ends of the shock-absorbing spring 903 respectively support the semicircular ring 901 and the slot 905, so that when the roller 803 contacts the brick body, it has a shock-absorbing and buffering effect, and the roller 803 is evenly stressed at both ends when working.

[0018] Preferably, in order to meet the requirements for long bricks to be stationed, a detachable support frame 10 is installed at the end of the telescopic frame 603, and casters 101 are set at the bottom of the support frame 10 to transfer the load-bearing gravity to the ground, so as to adapt to a larger load-bearing capacity without affecting the telescopic function of the telescopic frame 603; and the blocking plate 604 on the brick stationing platform is set as a rotatable structure, and the blocking plate 604 is connected to the vertical support rod 606 through an elastic connector, so that after the telescopic frame 603 is extended to the limit, the blocking plate 604 is squeezed by the brick body and can rotate, so that the brick body passes over the blocking plate 604 and is parked on the brick stationing platform, so that the mortar laying length and the brick stationing length are more adaptable.

[0019] Preferably, in order to meet the requirements of different ash laying thicknesses, adjusting screws are installed on the guide fence 4, and the guide fence 4 is set as an installation structure with a fixed horizontal position and adjustable up and down height. The position of the guide fence 4 is raised and lowered to drive the elevation of the ash laying device and the conveyor bed 2 to change, thereby achieving the requirements of adjusting various ash laying thicknesses.

[0020] Preferably, in order to facilitate cleaning and prevent the mortar in the ash trough 5 from contaminating the conveyor bed 2, a bridge 7 is installed below the ash trough 5. The bridge 7 is composed of a fixed frame 701 installed on the inner side of the track 601, a bearing 702, a rolling shaft 703, and a supporting roller 704 mounted on the rolling shaft 703. Both ends of the rolling shaft 703 are installed on the bearings 702 in the fixed frame 701. The bridge 7 supports the brick body, and the brick body is more stable below when passing through the ash trough 5 and is not easily damaged.

[0021] Preferably, the travel speed of the conveyor bed 2 is adjustable, and the size of the lower opening of the ash trough 5 is adjustable, so as to adjust the brick conveying and ash spreading speeds.

[0022] Working process of the mortar machine:

[0023] Put the bricks on the conveyor bed 2 between the guide piles 3. The conveyor bed 2 works to push the bricks at a uniform speed. After the previous brick is pushed through the conveyor bed 2, the next brick continues to push the previous brick forward. When passing the lower end of the mortar trough 5, since there is a specific distance between the mortar trough 5 and the brick surface, the mortar in the mortar trough 5 is smeared on the brick surface under the action of gravity. The brick body that has completed the mortaring continues to move forward and finally stops on the brick station, completing the mortaring task.

[0024] Beneficial effects:

[0025] ① The guide piles, guide fences and conveyor bed are combined to form a brick receiving port and a brick transport platform, which is convenient for brick entry and allows the bricks to move horizontally on the conveyor bed in the direction of the guide fence, providing favorable conditions for mortar laying.

[0026] ② Set the connection mode between the ash trough and the guide fence to a connecting rod connection to improve the adaptability of the ash spreading machine to complex environments.

[0027] ③ Set the brick station as a movable telescopic brick station to reduce the floor space occupied by the mortar laying machine, so as to achieve the purpose of convenient brick retrieval and easy machine installation.

[0028] ④Install rollers above the conveyor bed to meet the requirements for laying longer bricks, so that the laying length is not restricted. BRIEF DESCRIPTION OF THE DRAWINGS

The mortar is contained in the mortar troughs 5, and falls from the bottom and is spread flat on the bricks. After the bricks pass under the mortar troughs 5, they are suspended at the other end of the frame 1, waiting to be taken away.

[0045] Example 2

[0046] like Figure 3 , 4 As shown in Figures 5, 6 and 7, the automatic ash spreading machine described in this embodiment is basically the same as that described in Example 1, except that: the connection mode between the ash trough and the guide fence 4 is set to a connecting rod connection, the guide fence 4 is a hollow part, an upper connecting hole 501 and a lower connecting hole 401 are respectively set on both ends of the ash trough 5 and the guide fence 4, a spring 402 is installed in the inner cavity of the guide fence 4, and the spring 402 is in an unsaturated compression state.

When the push-pull device 806 is in motion, the suspended inner bracket 802 is squeezed downward, so that the inner bracket 802 rotates downward with the rotating shaft 804 as a fulcrum, driving the roller 803 to descend, forming a conveying mode of clamping the brick body up and down with the conveyor bed 2. An induction switch 807 is installed next to the roller 803. The induction switch 807 controls the push-pull device 806. When there are no bricks, the push-pull device 806 contracts, driving the inner bracket 802 and the roller 803 to rise and reset, and the brick inlet is opened. After sensing the brick body entering, the inner bracket 802 drives the roller 803 to descend and clamp the brick body.
