Description

Technical Field

[0001] This utility model relates to the field of concrete pipes, and in particular to a feeding device for reinforced concrete pipe manufacturing. Background Technology

[0002] Concrete pipes are pipes made of concrete or reinforced concrete; they are used to transport fluids such as water, oil, and gas; and can be divided into four types: plain concrete pipes, ordinary reinforced concrete pipes, self-stressed reinforced concrete pipes, and prestressed concrete pipes. The forming methods for concrete pipes include centrifugal forming, vibration forming, rolling forming, vacuum forming, and a combination of rolling, centrifugal forming, and vibration forming.

[0003] In the process of manufacturing reinforced concrete pipes, material feeding is required to facilitate the subsequent molding and production of reinforced concrete pipes. However, some existing material feeding and conveying devices may leave some raw materials stuck or remaining during the material conveying process. To avoid cross-contamination, cleaning is necessary. Some existing cleaning structures require machine shutdown for cleaning or replacement after problems occur. For example, the existing Chinese patent for a concrete pipe raw material pouring device, authorized announcement number CN209954951U, describes a "cleaning brush" that requires machine shutdown when cleaning or replacement is needed; otherwise, the material feeding and conveying device may miss cleaning areas.

[0004] Based on this, a material feeding device for reinforced concrete pipe manufacturing is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a feeding device for reinforced concrete pipe manufacturing, which aims to solve the problem that some existing feeding and conveying devices may stick or leave some raw materials during the material conveying process. In order to avoid cross-contamination, cleaning is required. Some existing cleaning structures require machine shutdown for cleaning or replacement after problems occur.

[0006] Specifically: A reinforced concrete pipe manufacturing and feeding device includes a cleaning device installed at the bottom of a feeding conveyor belt. The cleaning device is used to clean the feeding conveyor belt without stopping the machine. The feeding conveyor belt is used to feed reinforced concrete pipes during the manufacturing process. The cleaning device includes a cleaning conveyor belt and multiple unit cleaning racks. The multiple unit cleaning racks are arrayed on the cleaning conveyor belt. The cleaning conveyor belt uses multiple unit cleaning racks to sequentially and alternately attach to the bottom of the feeding conveyor belt, for cleaning or replacing itself during the non-stop cleaning of the feeding conveyor belt.

[0007] During the fabrication of reinforced concrete pipes, the feeding conveyor belt may pick up or leave some raw materials. To prevent cross-contamination, a cleaning conveyor belt and several unit cleaning racks are attached to the feeding conveyor belt for continuous cleaning. When the unit cleaning racks in contact with the feeding conveyor belt become dirty or damaged, the cleaning conveyor belt is activated to switch to another set of unit cleaning racks, which are then reattached to the feeding conveyor belt. This allows the cleaning conveyor belt to use multiple unit cleaning racks that are sequentially attached to the bottom of the feeding conveyor belt. This ensures that the cleaning conveyor belt can clean or replace itself during continuous cleaning, preventing any areas from being missed and ensuring the cleaning quality of the unit cleaning racks themselves, thus improving the cleaning effect and quality of the unit cleaning racks on the feeding conveyor belt.

[0008] In a specific embodiment of this application, the cleaning device further includes a support base, a cleaning conveyor belt is rotatably mounted inside the support base, and a cleaning chamber is provided inside the support base for cleaning multiple unit cleaning racks that are switched in; a maintenance chamber is provided inside the support base on the side of the cleaning chamber for replacing multiple damaged unit cleaning racks.

[0009] In a specific embodiment of this application, the cleaning conveyor belt includes a drive motor, which drives the chain to move multiple unit cleaning racks. The cleaning conveyor belt is also provided with multiple placement slots, which correspond one-to-one with the multiple unit cleaning racks. The unit cleaning racks are installed on the placement slots.

[0010] In a specific embodiment of this application, the unit cleaning rack includes a cleaning table and a support frame, the cleaning table being mounted on the support frame, and the support frame being mounted on the cleaning conveyor belt.

[0011] In a further specific embodiment, the cleaning table includes a support platform, which is mounted on a support frame; a scraper and a cleaning plate are installed on the side of the support platform away from the support frame, the scraper and the cleaning plate are arranged side by side, and the scraper is in front of the cleaning plate, which is used to first clean the feeding conveyor belt.

[0012] The cleaning plate includes multiple cleaning brushes and multiple discharge troughs, which are arranged alternately in sequence. Multiple discharge holes are opened inside the discharge troughs, and the discharge holes are distributed at equal intervals in a straight line along the discharge troughs.

[0013] The support platform has a liquid storage chamber inside, and multiple discharge holes are connected to the liquid storage chamber. A peristaltic pump is installed inside the liquid storage chamber. The peristaltic pump is used to move the cleaning liquid inside the liquid storage chamber to the multiple discharge holes and to use the multiple discharge holes to rinse the feeding conveyor belt. An injection pipe is installed on the support platform.

[0014] In a further specific embodiment, the support frame includes a guide plate, which is mounted on the cleaning conveyor belt. The guide plate has guide grooves, on which two guide sliders are slidably mounted. A support column is fixed at the center of the guide plate, and telescopic rods are mounted inside the guide grooves on both sides of the support column. One end of the telescopic rod is fixed to the support column, and the other end is fixed to the guide slider. The guide slider is fixed to the bottom of the cleaning table. An anti-detachment flange is provided on the guide plate to prevent the guide slider from falling off. During the process of the cleaning conveyor belt pressing multiple unit cleaning racks against the loading conveyor belt, the cleaning table uses a scraper in front of the cleaning plate to first scrape the loading conveyor belt, followed by multiple cleaning brushes to clean the loading conveyor belt. During this process, multiple discharge holes are used to rinse the loading conveyor belt, improving cleaning efficiency and effectiveness. Then, the telescopic rods are activated, and the telescopic rods use the guide sliders to drive the cleaning table to move periodically left and right to increase the cleaning coverage of each unit cleaning rack and avoid cleaning dead zones.

[0015] Compared with existing technologies, the new reinforced concrete pipe fabrication and feeding equipment can achieve the following:

[0016] During the fabrication of reinforced concrete pipes, the feeding conveyor belt may pick up or leave some raw materials. To avoid cross-contamination, a cleaning conveyor belt and several unit cleaning racks are attached to the feeding conveyor belt for continuous cleaning. When the unit cleaning racks in contact with the feeding conveyor belt become dirty or damaged, the cleaning conveyor belt is activated to switch to another set of unit cleaning racks, which are then reattached to the feeding conveyor belt. This allows the cleaning conveyor belt to use multiple unit cleaning racks that are sequentially attached to the bottom of the feeding conveyor belt. This process cleans or replaces the racks themselves during continuous cleaning of the feeding conveyor belt, preventing any areas from being missed and ensuring the cleaning quality of the unit cleaning racks themselves, thus improving the cleaning effect and quality of the unit cleaning racks on the feeding conveyor belt.

[0017] During the process of the cleaning conveyor belt pressing multiple unit cleaning racks against the feeding conveyor belt, the cleaning table uses a scraper in front of the cleaning plate to first scrape the feeding conveyor belt, and then uses multiple cleaning brushes to clean the feeding conveyor belt. During this process, multiple discharge holes are used to rinse the feeding conveyor belt to improve cleaning efficiency and effect. Then, the telescopic rod is activated, and the telescopic rod uses a guide slider to drive the cleaning table to move left and right periodically to increase the cleaning coverage of the unit cleaning racks and avoid cleaning dead corners.
