A connecting block 64 is fixedly connected to the end of the plug rod 63 outside the sleeve 61. Each connecting block 64 is fixedly connected to the inner side wall of the short side of the corresponding end of the dust hood 4. When the connecting spring 62 is in its natural state, the side of the dust hood 4 away from the tube 3 protrudes from the housing 21 of the laying end 2.

[0040] Reference Figure 1 and Figure 2 A blower 5 is also installed on the housing 21 of the laying end 2. The blower 5's blower pipe 51 is fixedly connected to the side wall of the material pipe 3 away from the dust hood 4. The material pipe 3 is provided with a sealing plate 7 to block the connection between the blower pipe 51 and the material pipe 3. The length of the sealing plate 7 is set along the length of the material pipe 3. A drive cylinder 8 is installed on the inner side wall of the material pipe 3 away from the dust hood 4. The drive cylinder 8 is located above the sealing plate 7, and the end of the extension rod of the drive cylinder 8 is fixed to the upper surface of the sealing plate 7.

[0041] When the induced draft fan 5 is working, the operator controls the drive cylinder 8 to work. The extension rod of the drive cylinder 8 moves downward, causing the sealing plate 7 to move downward, exposing the connection between the induced draft pipe 51 and the material pipe 3. At this time, the induced draft fan 5 can work normally. When the induced draft fan 5 is not working, the operator controls the drive cylinder 8 to work. The extension rod of the cylinder drives the sealing plate 7 to move upward, causing the sealing plate 7 to reset and seal the connection between the induced draft pipe 51 and the material pipe 3, reducing the occurrence of dust in the material pipe 3 entering the induced draft pipe 51.

[0042] Reference Figure 2 and Figure 4 The material pipe 3 is also equipped with a baffle assembly 9 to concentrate dust in the material pipe 3, so that the dust is concentrated in the material pipe 3, making it convenient for operators to collect and clean the dust. The baffle assembly 9 includes two guide plates 91 set in the material pipe 3. The length direction of the guide plates 91 is set along the length direction of the material pipe 3, and the two guide plates 91 are arranged along the height direction. Both guide plates 91 are located on the side of the material pipe 3 close to the dust collection hood 4, and the surfaces of the two guide plates 91 that are far apart from each other are hinged to the corresponding inner wall of the material pipe 3.

[0043] The material pipe 3 is further provided with a baffle plate 92 located on the side of the guide plates away from the dust cover 4, the length direction of the baffle plate 92 is consistent with that of the guide plates, and the position of the baffle plate 92 is aligned with the side of the two guide plates close to each other; the upper surface and the lower surface of the baffle plate 92 are both vertically and fixedly connected with a connecting rod 921, and the end of the connecting rod 921 away from the baffle plate 92 is fixedly connected with a protruding block 922.

[0044] The inner top surface and the inner bottom surface of the material pipe 3 are both provided with a groove 33 matched with the protruding block 922, the length direction of the groove 33 is arranged along the width direction of the material pipe 3, each protruding block 922 is slidingly inserted into the corresponding groove 33, and the cooperation between the protruding block 922 and the groove 33 enables the sliding cooperation between the baffle plate 92 and the material pipe 3; the side wall of the protruding block 922 away from the guide plate 91 is fixedly connected with a limiting spring 93, the limiting spring 93 is located in the groove 33, and the end of the limiting spring 93 away from the protruding block 922 is fixed to the corresponding groove wall of the groove 33; the limiting spring 93 limits the protruding block 922 and the baffle plate 92, so that there is a gap between the baffle plate 92 and the guide plate 91.

[0045] The material blocking assembly 9 further comprises a rotating member 94 for driving the guide plate 91 to rotate, the rotating member 94 comprises a horizontal rod 941 vertically fixed to the side wall of the baffle plate 92 close to the guide plate 91, and the horizontal rod 941 is located between the two guide plates 91; the end of the horizontal rod 941 away from the baffle plate 92 is fixedly connected with a rotating plate 942, the rotating plate 942 is located on the side of the guide plate 91 away from the baffle plate 92, and the rotating plate 942 is in contact with the two guide plates 91.

[0046] The side wall of the baffle plate 92 close to the guide plate 91 is further slidingly inserted with a guide rod 943 corresponding to the guide plate 91, the length direction of the guide rod 943 is arranged along the length direction of the horizontal rod 941; the guide rod 943 is located on the side of the guide plate 91 close to the baffle plate 92, the end of the guide rod 943 close to the guide plate 91 is fixedly connected with a cooperation plate 944, and each cooperation plate 944 is in contact with the corresponding guide plate 91; the guide rod 943 is sleeved with a rotating spring 945, one end of the rotating spring 945 is in abutment with the cooperation plate 944, the other end of the rotating spring 945 is in abutment with the baffle plate 92, the elastic force of the rotating spring 945 is smaller than that of the limiting spring 93, and the cooperation between the rotating spring 945, the cooperation plate 944 and the rotating plate 942 enables the guide plate 91 to remain vertical, and the cooperation between the two guide plates 91 prevents the dust in the guide plate 91 from drifting out of the material box.

[0047] The material blocking assembly 9 further comprises a driving piece 95 configured to drive the blocking plate 92 to move and drive the rotating piece 94 to work. The driving piece 95 comprises a sliding block 951 arranged on the side of the blocking plate 92 away from the guide plate 91. The sliding block 951 is T-shaped. The side wall of the blocking plate 92 away from the guide plate 91 is provided with a sliding groove 923 matched with the sliding block 951. The length direction of the sliding groove 923 is arranged along the height direction of the material pipe 3. The sliding block 951 is slidingly inserted into the sliding groove 923. The lower surface of the sliding block 951 is fixedly connected with a reset spring 952. The lower end of the reset spring 952 is fixed to the bottom groove wall of the sliding groove 923. The reset spring 952 supports the sliding block 951, so that the sliding block 951 is located on the upper portion of the blocking plate 92.

[0048] The sliding block 951 is hingedly connected with a hinge rod 953. The end of the hinge rod 953 away from the sliding block 951 is connected to the sealing plate 7. When the sealing plate 7 seals the position where the air duct 51 is communicated with the material pipe 3, the reset spring 952 and the limiting spring 93 are in the initial state. At this time, the two guide plates are in the vertical state. The end of the hinge rod 953 close to the sealing plate 7 is not higher than the end of the hinge rod 953 close to the blocking plate 92.

[0049] When the wall paper is laid on the laying working end 2, the wall paper is laid from bottom to top on the laying working end 2. The shell 21 drives the dust cover 4 to move, so that the dust on the wall surface can be cleaned before the wall paper is laid, reducing the manual cleaning and improving the laying efficiency of the wall paper laying robot.

[0050] When the laying working end 2 works, the side of the dust cover 4 away from the material pipe 3 is in contact with the wall surface. Since the distance between the laying working end 2 and the wall surface is not fixed when the wall paper is laid, the extension and contraction of the connecting spring 62 and the insertion rod 63 can ensure that the dust cover 4 is always in contact with the wall surface. After the dust cover 4 is in contact with the wall surface, the operator controls the driving cylinder 8 to work, drives the sealing plate 7 to move downward, and exposes the position where the air duct 51 is communicated with the material pipe 3.

[0051] When the driving cylinder 8 drives the sealing plate 7 to move downward, the sealing plate 7 drives the corresponding end of the hinge rod 953 to move downward. Meanwhile, the end of the hinge rod 953 close to the sliding block 951 moves toward the sealing plate 7. The hinge rod 953 drives the sliding block 951 and the blocking plate 92 to move toward the sealing plate 7. The blocking plate 92 is compressed while moving. The blocking plate 92 drives the horizontal rod 941 and the rotating plate 942 to move toward the sealing plate 7. The rotating plate 942 drives the two guide plates 91 to turn inward into the material pipe 3. The guide plates 91 are turned and drive the matching plate 944 to move toward the blocking plate 92. The movement of the blocking plate 92 further compresses the rotating spring 945.

[0052] When the blocking plate 7 is moved downward to the position, at this time, the side of the two flow guide plates 91 close to each other is inclined to the direction of the baffle 92, and the lower side of the upper flow guide plate 91 is not higher than the upper surface of the baffle 92, and the lower side of the lower flow guide plate 91 is not lower than the lower surface of the baffle 92; the air in the material pipe 3 is continuously sucked out by the air blower 5 through the air duct 51, so that the dust in the dust suction cover 4 is sucked into the material pipe 3, and the flow guide plate guides the airflow and the dust, so that the dust flows to the baffle 92, and the baffle 92 blocks the dust, so that the dust is left as much as possible between the flow guide plate 91 and the baffle 92.

[0053] When the tiling working end 2 is separated from the wall surface, the connecting spring 62 resets to drive the plug-in rod 63 and the dust suction cover 4 to move and reset; after the tiling is completed, the operator closes the air blower 5, and then controls the driving cylinder 8 to work, so that the blocking plate 7 moves upward to reset, and the corresponding end of the hinged rod 953 driven by the blocking plate 7 moves upward, and the end of the hinged rod 953 close to the sliding block 951 moves away from the blocking plate 7. The limiting spring 93 recovers and pushes the baffle 92 to move close to the flow guide plate 91.

[0054] The baffle 92 drives the horizontal rod 941 and the rotating plate 942 to move away from the blocking plate 7, and at the same time, the rotating spring 945 recovers the deformation and pushes the matching plate 944 and the guide rod 943 to move away from the blocking plate 7, the matching plate 944 pushes the flow guide plate 91 to rotate and reset, the flow guide plate 91 rotates and resets, and the two flow guide plates 91 cooperate to block the material pipe 3 again, so as to block the dust in the bin, reduce the situation that the dust is scattered to the outside of the material pipe 3, and facilitate the operator to collect the dust. When collecting the dust, the operator takes out the end cover 32, and uses a tool to scrape out the dust in the material pipe 3, and finally inserts the end cover 32 into the material pipe 3.

[0055] The implementation principle of the wall paper tiling robot in the embodiment of the application is as follows: when tiling the wall paper, the tiling working end 2 works, so that the dust suction cover 4 is in contact with the wall surface, the operator controls the driving cylinder 8 and the air blower 5 to work, the driving cylinder 8 drives the blocking plate 7 to move downward, and at the same time, the baffle 92 and the flow guide plate 91 move, so that the dust is concentrated between the baffle 92 and the flow guide plate 91; after the tiling is completed, the operator controls the driving cylinder 8 and the air blower 5 to work, the driving cylinder 8 works to drive the blocking plate 7 to move upward to reset, and at the same time, the baffle 92 and the flow guide plate 91 reset; when it is necessary to clean the dust, the operator takes out the end cover 32, and uses a tool to scrape out the dust in the material pipe 3, and finally inserts the end cover 32 into the material pipe 3.

[0056] The above are the preferred embodiments of the application, which do not limit the protection scope of the application, so: any equivalent changes made according to the structure, shape, principle of the application shall be covered within the protection scope of the application.
