Technical Field

[0001] This utility model relates to the field of building decoration technology, specifically to a device for beautifying and painting exterior walls in building decoration projects. Background Technology

[0002] The primary purpose of painting is to enhance aesthetics. While beautifying the wall surface, wall paint also protects it, providing excellent waterproofing and scratch resistance. Exterior wall paint is harder and more water-resistant than interior wall paint. It also needs to resist ultraviolet radiation and should not change color even after prolonged exposure to sunlight.

[0003] For example, application number CN202420952797.4 discloses a painting device for exterior walls in architectural decoration projects. The device includes a trolley, a lifting and painting mechanism, and a mixing and processing mechanism mounted on the trolley. The lifting and painting mechanism includes a support frame and a lifting plate. The support frame is mounted on the trolley, and a motor is mounted on the support frame.

A dredging mechanism is opened on the front side of the inner wall of the through groove.

[0007] In a preferred embodiment of this utility model, the unblocking mechanism includes an inclined mounting groove, which is located on the front side of the inner wall of the channel. The bottom of the inclined mounting groove extends to the bottom of the transfer box. A one-way valve is fixedly connected to the inner wall of the inclined mounting groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up a filter screen and a recycling bin, allows exterior wall paint dripping into the paint drip box. After dripping, the paint is transported through a conduit into a transfer box, then filtered by the filter screen in the channel, and finally transported again through the conduit into the recycling bin for storage. This solves the problem of waste paint dripping into the paint drip box being usable in non-critical areas where appearance and quality requirements are not high, such as the walls of internal storage rooms and equipment rooms of buildings, where the requirements for painting effect are relatively low. However, the waste paint from these equipment rooms accumulates directly in the paint drip box and cannot be recycled and stored in a timely manner, causing the exterior wall paint to easily solidify into a dried film, resulting in waste. This invention achieves the effect of assisting in recycling.

[0015] 2. This utility model has a clearing mechanism. When the painting device moves up and down, the L-shaped pressure plate moves up and down together. Then, when the L-shaped pressure plate moves down, it squeezes the airbag. The air in the airbag enters the channel through the one-way valve and blows air in the opposite direction to the filter screen, thereby blowing away the impurities accumulated on the filter screen and stabilizing the clearing of the filter screen. Then, when the L-shaped pressure plate moves up, the airbag returns to its original shape, preparing for the next squeezing.

[0016] 3. By setting a limiting mechanism, the groove in the perforated plate slides along the upright during the compression and recovery of the airbag, thereby limiting the airbag by the upright and the perforated plate, ensuring that the airbag is compressed and recovered vertically, and preventing the airbag from shifting or being damaged due to uneven force.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, this utility model provides an exterior wall beautification painting device 6 for building decoration projects, including a trolley 1, a mixing tank 2, a U-shaped frame 3, a motor 4, a reciprocating screw 5, a painting device 6, and a paint collection box 7. The bottom of the mixing tank 2 is fixedly connected to the left side of the top of the trolley 1. The two sides of the U-shaped frame 3 are fixedly connected to the two sides of the right side of the top of the trolley 1. The bottom of the motor 4 is fixedly connected to the top of the U-shaped frame 3, and the output end of the motor 4 extends through to the top of the inner wall of the U-shaped frame 3. The top of the reciprocating screw 5 is fixedly connected to the output end of the motor 4, and the bottom of the reciprocating screw 5 is movably connected to the right side of the top of the trolley 1 via a pin. The painting device 6... The inner wall of the device is threadedly connected to the reciprocating screw 5. The two sides of the painting device 6 are slidably connected to the two sides of the inner wall of the frame 3. The top left side of the paint drop box 7 is fixedly connected to the bottom right side of the painting device 6. The top front right side of the trolley 1 is fixedly connected to the support rod 8. The top of the support rod 8 is fixedly connected to the transfer box 9. The transfer box 9 is connected to the paint drop box 7 through a conduit. The bottom left side of the inner wall of the transfer box 9 is provided with a through groove 10. The inner wall of the through groove 10 is fixedly connected to the filter screen 11. The front side of the top of the trolley 1 is provided with a recycling bin 12. The recycling bin 12 is connected to the through groove 10 through a conduit. The front side of the inner wall of the through groove 10 is provided with a dredging mechanism 13.

[0024] refer to Figure 2 and Figure 3The unblocking mechanism 13 includes an inclined mounting groove 131, which is opened on the front side of the inner wall of the channel 10. The bottom of the inclined mounting groove 131 extends to the bottom of the transfer box. A one-way valve 132 is fixedly connected to the inner wall of the inclined mounting groove 131. A fixing block 133 is fixedly connected to the bottom of the left front side of the U-shaped frame 3. An airbag 134 is fixedly connected to the top of the fixing block 133. The bottom of the airbag 134 is fixedly connected to the one-way valve 132 through a conduit. An L-shaped pressure plate 135 is provided on the top of the airbag 134. The rear right side of the L-shaped pressure plate 135 is fixedly connected to the bottom of the left front side of the painting device 6. A limit mechanism 14 is fixedly connected to the top of the airbag 134.

[0025] As a technical optimization of this utility model, by setting up a dredging mechanism 13, when the painting device 6 moves up and down, the L-shaped pressure plate 135 moves up and down together. Then, when the L-shaped pressure plate 135 moves down, it squeezes the airbag 134. The air in the airbag 134 enters the channel 10 through the one-way valve 132 and blows air in the reverse direction on the filter screen 11, thereby blowing away the impurities accumulated on the filter screen 11 and stabilizing the dredging of the filter screen 11. Then, when the L-shaped pressure plate 135 moves up, the airbag 134 returns to its original state, preparing for the next squeezing.

[0026] refer to Figure 3 The limiting mechanism 14 includes an air vent plate 141. The bottom of the air vent plate 141 is fixedly connected to the top of the airbag 134. The inner wall of the air vent plate 141 is connected to the inner wall of the airbag 134. Slide grooves 142 are provided at the four corners of the top of the air vent plate 141. A vertical rod 143 is slidably connected to the inner wall of the slide groove 142. The bottom of the vertical rod 143 is fixedly connected to the four corners of the top of the fixing block 133. The inner side of the vertical rod 143 is in contact with the periphery of the surface of the airbag 134. A reset assembly 15 is fixed on the right side of the top of the air vent plate 141.

[0027] As a technical optimization of this utility model, by setting a limiting mechanism 14, during the process of the airbag 134 being compressed and restored, the sliding groove 142 in the air hole plate 141 slides along the upright 143, thereby making the upright 143 and the air hole plate 141 limit the airbag 134, ensuring that the airbag 134 is compressed and restored vertically, and preventing the airbag 134 from shifting or being damaged due to uneven force.

[0028] refer to Figure 1 The reset assembly 15 includes a tension spring 151. One end of the tension spring 151 is fixedly connected to the right side of the top of the vent plate 141, and the other end of the tension spring 151 is fixedly connected to a support block 152. The bottom of the support block 152 is fixedly connected to the front side of the left side of the U-shaped frame 3.

[0029] As a technical optimization of this utility model, by setting a reset component 15, when the L-shaped pressure plate 135 squeezes the airbag 134, the air hole plate 141 moves downward, the tension spring 151 is stretched, and a rebound force is generated. Then, when the L-shaped pressure plate 135 moves upward and the airbag 134 returns to its original state, the tension of the tension spring 151 causes the air hole plate 141 to move upward quickly to the reset position, allowing the airbag 134 to be quickly filled with air again, thereby stabilizing the cyclic squeezing operation of the airbag 134.

[0030] refer to Figure 3 Both sides of the top of the vent plate 141 are movably connected to anti-detachment plates 16, and the two sides of the bottom of the anti-detachment plates 16 are fixedly connected to the top of the upright 143.

[0031] As a technical optimization of this utility model, by setting an anti-detachment plate 16, when the air vent plate 141 rises and resets to a certain degree by the rebound force of the tension spring 151, the air vent plate 141 will collide with the anti-detachment plate 16 and stop there, thereby preventing the air vent plate 141 from rising excessively and detaching from the upright 143 due to the excessive inertia of the rebound force of the tension spring 151, which would affect the subsequent cyclic operation of the airbag 134.

[0032] refer to Figure 1 A sealing block 17 is fixedly connected to the front side of the bottom left side of the L-shaped pressure plate 135. The sealing block 17 is made of rubber.

[0033] As a technical optimization of this utility model, by setting a sealing block 17, when the L-shaped pressure plate 135 is pressed onto the vent plate 141, the sealing block 17 replaces it in contact with the vent plate 141, and deforms due to the compression, blocking the seal on the vent plate 141. Thus, the air in the airbag 134 can be stably compressed, opening the one-way valve 132.

[0034] refer to Figure 1 A groove 18 is provided on the front side of the top of the cart 1, and the bottom of the surface of the recycling bin 12 is slidably connected to the inner wall of the groove 18.

[0035] As a technical optimization of this utility model, by setting the groove 18, when the recycling bin 12 is placed on the cart 1, the recycling bin 12 can be inserted into the groove 18, so that the recycling bin 12 will not tilt or collapse due to bumps or inertial force during the movement of the cart 1.

[0036] The working principle and usage process of this utility model are as follows: When the user needs to paint the exterior wall of a house, first pour the exterior wall paint into the mixing bucket and mix it homogenously. Then, start the painting device 6 to spray the exterior wall paint onto the exterior wall. Next, start the motor 4 to drive the reciprocating screw 5 to rotate, causing the painting device 6 to move up and down repeatedly. This allows the coating roller on the painting device 6 to move up and down along the exterior wall, evenly brushing the previously sprayed paint. Afterward, the excess paint on the coating roller inside the painting device 6 is removed. The paint first falls into the paint collection box 7, then flows through the conduit into the transfer box 9, and then into the channel 10. After being filtered by the filter screen 11, impurities from the exterior wall mixed in with the paint are intercepted in the transfer box 9. Finally, it flows through the conduit into the recycling bin 12. During this process, as the painting device 6 moves up and down, the L-shaped pressure plate 135 moves up and down together. When the L-shaped pressure plate 135 moves downward, it pushes the air vent plate 141 to squeeze the air bag 134. The air in the air bag 134 enters through the one-way valve 132. The channel 10 blows air in the opposite direction onto the filter screen 11, thereby blowing away the impurities accumulated on the filter screen 11 and stabilizing the filter screen 11. At the same time, the tension spring 151 is stretched by the descent of the vent plate 141, generating a rebound force. Then, when the L-shaped pressure plate 135 moves upward, the tension of the tension spring 151 causes the vent plate 141 to move upward quickly to its reset position, allowing the airbag 134 to be quickly refilled with air. During this process, the sliding groove 142 in the vent plate 141 moves along the upright 14. 3. Sliding causes the upright 143 and the vent plate 141 to limit the airbag 134, ensuring the vertical compression and recovery of the airbag 134, thereby stabilizing the cyclic squeezing operation of the airbag 134. Finally, the filter screen 11 is blown by the air, keeping it unobstructed and stabilizing the filtration of the exterior wall paint. Thus, the exterior wall paint stored in the recycling bin 12 can be used in non-critical areas where appearance and quality requirements are not high, reducing waste and loss, and thus having the advantage of auxiliary recycling.

[0037] In summary, this exterior wall beautification painting device for building decoration projects, by setting up a filter screen 11 and a recycling bin 12, allows exterior wall paint to drip into the paint drip box 7, then be transported through a conduit into a transfer box 9, and then filtered by the filter screen 11 in the channel 10 before being transported again through the conduit into the recycling bin 12 for storage. This solves the problem of waste paint dripping into the paint drip box being used in non-critical areas where appearance and quality requirements are not high, such as the walls of internal storage rooms and equipment rooms of buildings, where the requirements for painting effect are relatively low. However, the aforementioned equipment waste paint directly accumulates in the paint drip box and cannot be recycled and stored in time, causing the exterior wall paint to easily solidify into a dried film, thus causing waste.
