With the continuous improvement of the foundry industry's requirements for productivity, mechanized molding line has been widely used in casting production. How to reduce the labor intensity of workers and realize the automatic operation of mechanized molding line, the most critical thing is how to realize the automatic cycle of sand box pushing, poking and returning. At present, the return roller of the mechanized molding line mostly adopts the method of installing support rollers on the brackets on both sides or installing straight rollers between the brackets. Each of these methods has disadvantages. When the support rollers are used to operate the sand box, since the support rollers on both sides are hollow and the contact area between the support rollers and the sand box is small, if the sand box is offset, it is easy to fall off the support rollers, resulting in production accidents such as box falling off, affecting the production operation of the entire molding line; when the sand box is operated on a straight roller, since there is no limit on both ends of the roller, the sand box is easy to deviate during the pushing process and collide with the brackets on both sides. It only relies on the brackets for blocking and correction, which often causes friction between the sand box and the bracket, damaging the production equipment, reducing its service life, increasing related maintenance costs, and low production efficiency.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings:

[0021] like Figure 1 As shown, in the prior art, the return box roller adopts a straight roller structure, and an adjusting bracket 4 is installed on the foundation 6 where the molding line is set. The original roller bracket 01 is fixedly installed on the adjusting bracket 4. The original roller bracket 01 is L-shaped, and the two ends of the straight roller 02 are directly placed and mounted above the original roller bracket 01. The sand box is transported back to the box through the top of the straight roller 02. It is easy to deviate during the production process. The sand box slides out from the top of the two ends of the straight roller 02, and friction and collision occur between the original roller bracket 01, affecting the circulation and operation of the entire molding line.

[0022] In order to avoid the above situation, the utility model provides a new box return roller for molding line, combined with Figures 2 to 4As shown, it includes two roller supports 1 that are parallel to each other and arranged at intervals, and a number of return box rollers 2 installed on the roller supports 1 and arranged at equal intervals. According to the actual production layout requirements of the molding line, a plurality of embedded base plates 7 are fixedly installed on the foundation 6 at the designated setting position of the return box roller, two by two in a horizontal group, and a group of adjusting supports 4 are fixedly installed on each group of embedded base plates 7. The adjusting supports 4 include two lifting bases 41, adjusting bolts 42 and supporting and fixing seats 43 respectively arranged on the corresponding embedded base plates 7. The lifting base 41 is installed above the embedded base plate 7 by adjusting bolts 42 on both end sides thereof, and the height of the lifting base 41 can be adjusted up and down. A horizontal supporting and fixing seat 43 is mounted on the two lifting bases 41, and the setting length of the supporting and fixing seat 43 is greater than the spacing between the two roller supports 1. The above-mentioned two roller supports 1 are fixedly installed on the two ends of the supporting and fixing seat 43 by bolts, symmetrically, and the spacing distance between them is greater than the width of the sand box 8. Each roller support 1 is made of welded channel steel and includes multiple sections, which are connected and arranged in sequence. A set of adjustment supports 4 is arranged directly below the joint between each two adjacent roller supports 1, and the ends of the roller supports 1 are fixed to the support and fixing seats 43 of the adjustment supports 4 by bolts. A number of return rollers 2 are set between the two roller supports 1. Each return roller 2 includes a cylindrical main roller body 21, cam baffles 22 arranged at both ends of the main roller body 21, and a roller shaft 23. The cam baffle 22 is coaxially mounted on the main roller body 21, and the two are relatively fixed; the outer diameter of the cam baffle 22 is larger than the outer diameter of the main roller body 21, and a boss-like structure is formed between the end of the main roller body; the distance between the two cam baffles 22 is exactly the same as the width of the sand box 8, so that the bottom of the sand box 8 is just stuck between the two cam baffles 22, located between the main roller body 2 1 is circulated directly above; a roller shaft 23 is coaxially fixed to each of the two ends of the main roller body 21, and the free ends of the roller shaft 23 extend to both sides, pass through the roller support 1 on the corresponding side, and are rotatably fixed to the outer wall of the roller support 1 through the seat bearing 3. The free end of the roller shaft 23 and the inner side of the seat bearing 3 are positioned and installed using a shoulder; at the same time, an elastic retaining ring can be installed on the outer end of the roller shaft 23 extending from the seat bearing 3 to limit and fix it, so as to prevent the return box roller 2 from sliding left and right between the two roller supports 1; the seat bearing 3 is a deep groove ball bearing. The setting heights of the above-mentioned return box rollers 2 are consistent to ensure that the sand box 8 completes the return box operation in a straight line; the spacing between two adjacent return box rollers 2 is about one-third of the length of the sand box 8, so as to ensure that the sand box 8 always has three return box rollers 2 at its bottom to support its operation stability during operation.

[0023] A further optimized technical solution is that a box stop frame 5 vertically perpendicular to the supporting fixed seat 43 is fixedly installed on the above-mentioned adjustment bracket 4 located at the end of the entire box return roller, so as to complete the positioning and blocking of the sand box 8 to facilitate the connection with the next molding line process.

[0024] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
