TECHNICAL FIELD
[0001] The utility model relates to the field of concrete, specifically is a concrete waterproofing agent processing production feeding device. BACKGROUND
[0002] With the rapid development of infrastructure construction in China, the demand for building waterproofing is increasing. Traditional waterproofing materials have been unable to meet the high requirements of modern buildings on waterproofing performance, so the demand for new waterproofing materials in the market is increasing. In order to improve the waterproofing performance, various types of waterproofing agents have been developed, including organic waterproofing agents, inorganic waterproofing agents, and high-molecular waterproofing agents. These waterproofing agents are widely used in concrete waterproofing, roofing, basement waterproofing and other fields according to different construction engineering requirements. Among them, concrete waterproofing agent is an additive that can effectively reduce the water absorption and permeability of concrete. By reducing the pore and blocking the capillary channel, it can significantly improve the waterproofing performance of concrete. In use, concrete waterproofing agent usually needs to be mixed with concrete or coated on the surface of the building as waterproofing paint to achieve waterproofing effect. However, due to the high requirement of waterproofing performance, the proportioning and processing precision of waterproofing agent in the production process have strict requirements.
[0003] In the processing and production process of concrete waterproofing agent, the feeding device as one of the key equipment directly affects the production efficiency and product quality of waterproofing agent. However, the existing concrete waterproofing agent feeding device generally has some problems, especially after multiple discharges, it is easy to appear the phenomenon of blockage. The main reason is that the waterproofing agent coating cannot be completely extruded during the feeding process, resulting in accumulation in the feeding pipe and hardening on the surface, thereby forming blockage. This blockage not only affects the continuous operation of the production line, but also increases the workload of cleaning and maintenance, and in severe cases may cause production interruption, affecting production efficiency; therefore, a concrete waterproofing agent processing and production feeding device is proposed to solve the above problems.

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.
[0022] Example 1
[0023] Please see Figures 1-4As shown, a concrete waterproofing agent processing and production feeding device includes a material guide trough 1, which is a cylindrical structure with one end closed and the other end open. A feeding hopper 5 is fixed to the top of the material guide trough 1. The closed end of the material guide trough 1 is provided with a pushing component for pushing out the material inside the material guide trough 1, and the open end of the material guide trough 1 is provided with a shielding component for closing the material guide trough 1. An observation window 3 is fixed to the outer wall of the material guide trough 1 near the open end. During operation, the open end of the material guide trough 1 is first closed using the shielding component. Waterproofing agent coating is added to the material guide trough 1 through the feeding hopper 5. When the operator observes through the observation window 3 that the material inside the material guide trough 1 has reached a specified height, the addition of waterproofing agent coating is stopped. Then, the shielding component is opened, and the pushing component is used to push the waterproofing agent coating inside the material guide trough 1 out from the open end, which facilitates material discharge and increases the material discharge speed.
[0024] The feeding assembly includes a pusher plate 11 that is slidably and sealed inside the feed trough 1. A rectangular through hole 12 is formed at the center of the end of the feed trough 1. A U-shaped frame 7 is fixed to the outer wall of the feed trough 1. An internally threaded sleeve 13 is fixed to the side of the pusher plate 11. The internally threaded sleeve 13 slides through the through hole 12 and extends to the middle of the U-shaped frame 7. The outer contour of the internally threaded sleeve 13 is adapted to the through hole 12. A lead screw 14 is threadedly connected to the middle of the internally threaded sleeve 13. A drive mechanism is fixed on the U-shaped frame 7. The motor 8 rotates the lead screw 14. During operation, the motor 8 is started. The motor 8 rotates in both directions and drives the lead screw 14 to rotate. In turn, the lead screw 14 pushes the internal threaded sleeve 13 to move along the through hole 12 into the guide groove 1. Simultaneously, it pushes the push plate 11 to move along the guide groove 1, pushing the waterproofing agent coating inside the guide groove 1 out of the opening and increasing the feeding speed. The push plate 11 is completely in contact with the inner wall of the guide groove 1, which can completely empty the waterproofing agent coating inside the guide groove 1 and prevent it from causing blockage after drying.
[0025] The shielding assembly includes a housing 2, which is fixedly connected to the outside of the opening of the material guide trough 1. A baffle 9 is slidably installed inside the housing 2, and the size of the baffle 9 is adapted to the size of the opening of the material guide trough 1. The baffle 9 completely closes the opening of the material guide trough 1. A pull rod 4 is fixed to the middle of the side of the baffle 9, and the pull rod 4 slides through a rectangular through hole 15 opened on the housing 2. During operation, the outline of the baffle 9 is adapted to the inner wall of the housing 2, so that the baffle 9 can only move in a straight line along the inside of the housing 2. It is convenient to directly push the baffle 9 with the pull rod 4 to completely close the opening of the material guide trough 1, preventing the leakage of the waterproofing agent coating inside the material guide trough 1. When discharging, the opening can be opened by directly pulling the baffle 9, so that the waterproofing agent coating inside the material guide trough 1 can be pushed out by the material pushing assembly, which is convenient for discharging.
[0026] A spring 10 is sleeved in the middle of the pull rod 4. During operation, the spring 10 is positioned between the inner wall of the housing 2 and the baffle 9. The spring 10 pushes the baffle 9 to fit tightly against the opening of the guide trough 1, resulting in a better sealing effect.
[0027] The feed hopper 5 is equipped with a control valve 6; during operation, the waterproofing agent coating in the feed hopper 5 is controlled by the control valve 6 to enter the guide trough 1.
[0028] A limiting component is provided on the outer wall of the housing 2 above the pull rod 4. The limiting component includes a limiting rod 17. A fixing block 18 and a fixing block 21 are fixedly connected from bottom to top on the outer wall of the housing 2 above the pull rod 4. The limiting rod 17 slides vertically through the middle hole of the fixing block 18 and the fixing block 21 to limit the movement direction of the limiting rod 17. The bottom end of the limiting rod 17 is inclined. A limiting hole 16 adapted to the bottom end of the limiting rod 17 is opened on the upper end face of the pull rod 4. During operation, the limiting rod 17 is pulled upward, and then the pull rod 4 is pulled outward. The pull rod 4 drives the baffle 9 to move, opening the opening. The limiting rod 17 is then vertically inserted into the limiting groove at the top of the pull rod 4 to limit the pull rod 4, thereby restricting the position of the baffle 9. This ensures that the opening of the material guide trough 1 remains open, facilitating continuous material feeding.
[0029] Example 2
[0030] Please see Figure 3 As shown in the comparative embodiment one, as another implementation of this utility model, a fixing plate 19 is fixed in the middle of the limiting rod 17. The fixing plate 19 is disposed between the fixing block 18 and the fixing block 21. A spring 20 is installed above the fixing plate 19. The spring 20 is sleeved on the limiting rod 17 and its top end abuts against the fixing block 21. During operation, when the pull rod 4 moves, the limiting groove on the upper end of the pull rod 4 contacts the inclined surface at the bottom end of the limiting rod 17, pushing the limiting rod 17 to move automatically upward. Then, the spring 20 pushes the fixing plate 19 and the limiting rod 17 to automatically descend and insert into the limiting groove, so as to realize the automatic limiting of the pull rod 4, reduce the difficulty of work, and improve the work efficiency.
[0031] Working principle: First, the open end of the guide chute 1 is closed using the shielding component. Waterproofing agent is added to the guide chute 1 through the feed hopper 5. When the operator observes through the observation window 3 that the material inside the guide chute 1 has reached the designated height, the addition of waterproofing agent is stopped. The pull rod 4 drives the baffle 9 to move, causing the open end to open. During the movement of the pull rod 4, the limiting groove on the upper end of the pull rod 4 contacts the inclined surface at the bottom of the limiting rod 17, pushing the limiting rod 17 to move automatically upward. Then, the spring 20 pushes the fixing plate 19 and the limiting rod 17 to automatically descend and... It is inserted into the limiting groove to automatically limit the pull rod 4, thereby limiting the position of the baffle 9, so that the opening of the guide trough 1 is always kept open for continuous material feeding; the motor 8 is started. The motor 8 is a forward and reverse rotating motor. The motor 8 drives the lead screw 14 to rotate, and then pushes the internal threaded sleeve 13 along the through hole 12 into the guide trough 1 through the lead screw 14. At the same time, it pushes the push plate 11 along the guide trough 1 to push the waterproofing agent coating inside the guide trough 1 out of the opening and increase the feeding speed.
