[0020] Taking the transportation of the working box 4 of the 3DP sand mold printing device as an example, the specific implementation means of this embodiment is described in detail.

[0021] A transmission device for a working box 4 of a 3DP sand mold printing device comprises an endless chain 1 for carrying the working box 4, a driving mechanism 2 for driving the chain 1, a follower mechanism and a guide mechanism 3 for driving the working box 4, wherein the follower mechanism is arranged at the bottom of the working box 4, and the working box 4 is located on the chain 1, so as to achieve the purpose of entering and exiting the 3DP sand mold printing device.

[0022] As a supplement to this embodiment, the driving mechanism 2 includes a first mounting member arranged at both ends of the guide rail mechanism, a motor arranged on the first mounting member and a sprocket arranged on the motor. The motor is mounted on the first mounting member at an angle perpendicular to the horizontal direction of the output shaft, and the sprocket is mounted on the motor output shaft with the end face horizontal, thereby realizing the rotational movement of the sprocket in the horizontal plane.

[0023] As a further supplement to this embodiment, the chain 1 is meshed on the sprocket so that the side end surface of the chain 1 is horizontal, thereby avoiding the problem of the chain 1 falling due to the horizontal front surface of the chain 1, and well ensuring that the working box 4 is always in a horizontal state.

[0024] As a further supplement to this embodiment, the guide mechanism 3 is arranged inside the working space of the 3DP sand mold printing device, and the guide mechanism 3 is arranged in pairs at the box outlet and box inlet of the 3DP sand mold printing device; specifically, the guide mechanism 3 is fixedly arranged on the ground where the 3DP sand mold printing device is arranged, and is placed in the frame of the 3DP sand mold printing device to determine the running track of the working box 4. In this embodiment, the guide mechanism 3 is an L-shaped guide rail, which is provided with four rails, two of which are arranged at the box inlet and two of which are arranged at the box outlet. In one application mode, the driving mechanism 2 is respectively arranged at both ends of a guide rail at the box inlet to realize the box inlet transfer of the working box 4, and it is a unilateral power transfer; it is also possible to set the driving mechanism 2 at both ends of the two guide rails at the box inlet to realize the bilateral power transfer of the working box 4. In this case, the box inlet and the box outlet are shared, and the box outlet and the box inlet are staggered and alternate. In another embodiment, the driving mechanism 2 is respectively arranged at both ends of a guide rail of the box inlet, and the driving mechanism 2 is respectively arranged at both ends of a guide rail of the box outlet, thereby realizing unilateral power transfer of the working box 4 in and unilateral power transfer of the working box 4 out of the box; more preferably, one driving mechanism 2 is respectively arranged at both ends of each guide rail of the box inlet, and one driving mechanism 2 is respectively arranged at both ends of each guide rail of the box outlet, thereby realizing bilateral power transfer of the working box 4 in and bilateral power transfer of the working box 4 out of the box; this embodiment realizes the synchronization of the entry and exit of the working box 4, that is, the working box 4 whose printing job is completed is transferred out from the box outlet, and at the same time, the spare working box 4 is transferred into the 3DP sand mold printing equipment from the box inlet, thereby improving the transfer efficiency of the working box 4 and shortening the waiting time of the 3DP sand mold printing equipment.

Specifically, the follower mechanism includes a second mounting member and a bearing follower, the second mounting member is arranged at the bottom of the working box 4, and the bearing follower is arranged on the second mounting member; the bearing follower cooperates with the guide mechanism 3 to realize the operation of the working box 4 on the guide mechanism 3. The follower mechanism reduces the static friction between the guide mechanism 3 and the working box 4, reduces the wear and loss of the working box 4, and adopts positioning between mechanical structures to improve the stability of the transmission device.

[0026] like Figure 1 and Figure 2 As shown, the working position of the 3DP sand mold printing device, that is, the printing working position of the working box is set at one end of the guide mechanism 3, that is, one end of the guide mechanism 3 is inside the 3DP sand mold printing device, and the other end is outside the 3DP sand mold printing device; in the case where the 3DP sand mold printing device is provided with a box inlet and a box outlet with separate independent functions, when the box inlet and the box outlet are both provided with the transmission device described in the utility model, the printing working position is located between the driving mechanism 2 of the box inlet transmission device placed inside the 3DP sand mold printing device and the driving mechanism 2 of the box outlet transmission device placed inside the 3DP sand mold printing device, thereby conveniently realizing the switching of the working box inlet and out of the box.

[0027] The above embodiments are merely descriptions of a typical application of the technical solution of the utility model, and reasonable expansion can be carried out on a reasonable basis without requiring creative work.
