Preferably, both between the transmission connecting rod 54 and the first transmission shaft 52 and between the transmission connecting rod 54 and the second transmission shaft 53 are connected through a fish - eye joint 55. When the cleaning drive source 20 acts, it drives the transmission crank 51 to rotate, and through the first transmission shaft 52, the fish - eye joint 55, the transmission connecting rod 54, and the second transmission shaft 53, the transmission slider 30 and the cleaning scraper 40 are driven to reciprocate back and forth.

[0058] Preferably, as Figure 1 shown, the pipe mold cleaning mechanism further includes a guide shaft 60 that extends straight back and forth along the moving direction of the transmission slider 30. There are two guide shafts 60 arranged up and down, and both guide shafts 60 are fixed to the cleaning frame 10. The transmission slider 30 is supported and installed on the guide shaft 60 so as to be movable back and forth. Through the guiding cooperation between the guide shaft 60 and the transmission slider 30, the smoothness of the forward and backward movement of the transmission slider 30 is improved, and the cleaning effect of the cleaning scraper 40 cleaning the rabbet surface 110 of the edge of the pipe mold and the sealing groove 120 is better ensured. Of course, in other embodiments, the number of guide shafts 60 can also be set to other numbers, such as one or three.

[0059] Preferably, the guide shaft 60 is a circular shaft, and the shaft hole in the transmission slider 30 that mates with the guide shaft 60 is a circular hole; alternatively, the guide shaft 60 is a rectangular shaft, and the shaft hole in the transmission slider 30 that mates with the guide shaft 60 is a rectangular hole. The combination structure of the transmission slider 30 and the guide shaft 60 can be: the transmission slider 30 is installed on the guide shaft 60 through a linear bearing so as to be movable back and forth, realizing the sliding fit between the two; or, the sliding fit between the transmission slider 30 and the guide shaft 60 is realized through a dovetail groove structure.

[0060] Furthermore, as Figure 3 or Figure 4 shown, the tube mold cleaning mechanism further includes a tool fixing component connected between the transmission slider 30 and the cleaning scraper 40. The tool fixing component includes a scraper mounting block 71 and a scraper mounting plate 72; a tool fixing groove 31 is formed in the transmission slider 30, and the tool fixing groove 31 penetrates through the transmission slider 30 from left to right and extends forward to the front end of the transmission slider 30; the scraper mounting block 71 includes a mounting block body 711 embedded in the tool fixing groove 31 and a plate fixing protrusion 712 extending forward from the mounting block body 711; the scraper mounting plate 72 is distributed on the front side of the scraper mounting block 71, and a mounting positioning groove 721 is formed at the upper end of the scraper mounting plate 72, and the mounting positioning groove 721 is a U-shaped groove; the plate fixing protrusion 712 is inserted into the mounting positioning groove 721 to realize the positioning during the installation of the scraper mounting plate 72; the plate fixing protrusion 712 and the scraper mounting plate 72 are fixedly connected by several screws, thereby fixing the scraper mounting plate 72 to the scraper mounting block 71; and the cleaning scraper 40 is fixed to the lower end of the scraper mounting plate 72 by several screws.

[0061] Furthermore, in the tool fixing component of the tube mold cleaning mechanism, the installation structure of the mounting block body 711 of the scraper mounting block 71 in the tool fixing groove 31 of the transmission slider 30 preferably has the following two types.

[0062] Method 1: As Figure 3 shown, the mounting block body 711 and the transmission slider 30 are fixedly connected by bolts, thereby embedding and fixing the mounting block body 711 of the scraper mounting block 71 in the tool fixing groove 31 of the transmission slider 30.

[0063] Method 2: As Figures 4 to 6As shown in the figure, the fixed knife assembly further includes a fixed knife support shaft 73 and a scraping knife spring 74 that both extend vertically. The fixed knife support shaft 73 is distributed in the fixed knife groove 31 and fixed to the transmission slider 30. The main body 711 of the mounting block is supported by an oil-free bushing to be movable up and down on the fixed knife support shaft 73. The scraping knife spring 74 abuts between the transmission slider 30 and the top of the main body 711 of the mounting block, thereby embedding the main body 711 of the scraping knife mounting block 71 in the fixed knife groove 31 of the transmission slider 30 in a floating manner up and down. In this way, during the cleaning process, the scraping knife spring 74 acts on the scraping knife mounting block 71, making the cleaning scraping knife 40 tightly abut against the rabbet surface 110 and the sealing groove 120 of the pipe mold. However, when encountering a protruding hard object, it also allows the cleaning scraping knife 40 to float up a certain distance, making the cleaning scraping knife 40 durable, reducing the failure rate, and improving the adaptability to the pipe mold.

[0064] Preferably, there are two fixed knife support shafts 73, which are distributed on the left and right sides of the scraping knife spring 74. A blind hole is provided at the top of the main body 711 of the mounting block, and the lower section of the scraping knife spring 74 is accommodated in the blind hole of the main body 711 of the mounting block. In addition, the cleaning scraping knife 40 is made of carbon steel, which has good rigidity and improves the service life of the cleaning scraping knife 40.

[0065] Furthermore, as Figure 1 , Figure 2 and Figure 7 shown in the figure, the pipe mold cleaning mechanism further includes a guiding support 80 fixed to the bottom of the cleaning frame 10, and several guiding wheels 90 rotatably mounted on the guiding support 80. The several guiding wheels 90 are arranged front and back. The guiding wheel 90 includes a wheel main body part 91 and a wheel flange part 92 protruding from the wheel main body part 91. During the cleaning process of the pipe mold, the wheel main body part 91 is in rolling cooperation with the rabbet surface 110 of the pipe mold edge, and the wheel flange part 92 is located in the sealing groove 120 of the pipe mold edge and in rolling cooperation with the sealing groove 120. In this way, the overall guiding of the pipe mold cleaning mechanism is realized through the guiding wheels 90.

[0066] In summary, the present application can effectively clean the rabbet surface 110 and the sealing groove 120 of the pipe mold edge, with good cleaning effect, high cleaning efficiency, reliable overall structure, good adaptability to the pipe mold, greatly improving the quality of pipe mold cleaning, being beneficial to the fully automatic unmanned operation of the prestressed pipe pile automatic production line, and meeting the development needs of automatic production equipment.
