Description

Technical Field

[0001] This utility model relates to the field of box flipping machine technology, and in particular to an automatic box flipping machine. Background Technology

[0002] After being stir-fried, hot pot base is usually in a high-temperature, semi-fluid state with high fluidity. After being packaged and cooled, the base gradually cools and solidifies, forming a solid or semi-solid block structure, which facilitates subsequent quantitative packaging and mechanized operations.

[0003] The cooling boxes are generally recycled. After the square hot pot base is demolded, the inside of the square empty box is cleaned, disinfected, and dried before being put back into the production line.

[0004] During the cleaning process, empty boxes are usually facing downwards and need to be rotated 180° before they can be conveyed to the front end for further filling. Currently, workers manually rotate them, which is not only inefficient but also has high labor costs, making it difficult to meet production requirements. Utility Model Content

[0005] The purpose of this invention is to solve the problem of low efficiency caused by manually flipping empty boxes in the existing technology, and to propose an automatic box flipping machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic box-turning machine includes a frame and a table fixedly connected to the frame. A box is fixedly connected to the table, and a turning conveyor for turning empty boxes 180° is installed inside the box. The box has an inlet and an outlet at both ends. The turning conveyor includes two sets of conveyor lines symmetrical about a center line L. A spiral conveying channel is formed between the inner walls of the two sets of conveyor lines. The two ends of the conveying channel are connected to the inlet and the outlet, respectively.

[0008] To facilitate the flipping of empty boxes, preferably, the conveyor line includes: a first rotating shaft, a second rotating shaft, and a third rotating shaft, wherein the first rotating shaft, the second rotating shaft, and the third rotating shaft are all rotatably connected inside the box, the first rotating shaft and the second rotating shaft are parallel to each other, and the first rotating shaft and the second rotating shaft are both spatially perpendicular to the third rotating shaft; at least two connecting belts with an annular structure are sequentially sleeved on the first rotating shaft, the third rotating shaft, and the second rotating shaft, and a motor for driving the third rotating shaft to rotate is provided on the frame.

[0009] To further reduce the torsion on the empty box, the third rotating shaft is provided in two parts.

[0010] Furthermore, a mounting bracket is fixedly connected to the platform, and both the first and second rotating shafts are rotatably connected to the mounting bracket, with the first and second rotating shafts distributed vertically.

[0011] In order to enable the conveying and flipping of empty boxes with a small height, preferably, a fan is fixedly connected inside the frame, and an air outlet pipe is fixedly connected inside the box. The output end of the fan is connected to the air outlet pipe through a pipe, and the air outlet pipe is directed toward the point where the empty box in the flipping conveyor section switches from vertical to horizontal.

[0012] Preferably, an observation cover is detachably connected to the top of the box, and the observation cover is fixedly connected to a transparent observation port.

[0013] Compared with the prior art, this utility model provides an automatic box-turning machine, which has the following beneficial effects:

[0014] 1. This automatic box flipping machine forms an approximately spiral-shaped conveying channel between its inner walls through the twisting of two sets of conveyor lines. When the empty box moves from one end of the conveyor channel to the other end, the empty box flips 180° without manual intervention. When used in conjunction with a production line, it can achieve continuous flipping, which helps to improve production efficiency and reduce labor costs.

[0015] 2. This automatic box-turning machine, by installing a fan inside the frame and directing the air outlet towards the point where the empty box transitions from vertical to horizontal, especially when the height of the empty box is less than the width of the conveying channel, can reduce the possibility of the empty box falling at the turning point. At this time, starting the fan and blowing air through the air outlet onto the empty box can speed up the transition process, reduce the suspension time, and allow it to smoothly transition from a vertical to an inclined state, ensuring the conveying and turning effect of low-height empty boxes.

[0016] The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model forms an approximately spiral-shaped conveying channel between the inner walls of two sets of conveyor lines through their twisting. When the empty box moves from one end of the conveying channel to the other end, the empty box rotates 180° without manual intervention. When used in conjunction with a production line, it can achieve continuous rotation, which helps to improve production efficiency and reduce labor costs. Attached Figure Description

[0025] Example:

[0026] Reference Figures 1-5An automatic box-turning machine includes a frame 1 with adjustable feet fixedly connected to the bottom for leveling the frame 1. The frame 1 is made of stainless steel. It also includes a table 101 fixedly connected to the frame 1, a box body fixedly connected to the table 101, and an observation cover detachably connected to the top of the box body. The observation cover can be directly placed on the top of the box body, or one end of the observation cover can be hinged to the box body for rotation, with the other end abutting against the top of the box body. A transparent observation port is fixedly connected to the observation cover for easy observation of the conveying process inside the box body. A turning conveyor unit for turning empty boxes 180° is installed inside the box body, and inlet and outlet ports are respectively opened at both ends of the box body. The turning conveyor unit includes two sets of conveyor lines symmetrical about a center line L. That is, one set of conveyor lines can rotate 180° around the center line L to obtain the other... The system consists of two conveyor lines forming a rotating conveyor section. A spiral conveying channel is created between the inner walls of the two lines, connecting the inlet and outlet at both ends. During operation, the empty box enters the box through the inlet and moves along the conveyor channel towards the outlet. As it moves, the box changes from a horizontal to a vertical position, then back to a horizontal position with the opening facing upwards, achieving a 180° rotation. Finally, it exits the box with the opening facing upwards, facilitating the subsequent filling of liquid hot pot base into the empty box. This system allows for continuous box rotation and can be integrated into a production line. With one end as the inlet and the other as the outlet, all empty boxes rotate 180° without manual intervention. The inlet and outlet speeds can be matched to the speed of the connecting conveyor, improving production efficiency and reducing labor costs.

[0027] Reference Figure 1 , Figure 2 and Figure 5Here, we design the conveyor line as follows: a first rotating shaft 2, a second rotating shaft 201, and a third rotating shaft 202. Preferably, we provide two third rotating shafts 202. By extending the length of the vertical section, we can reduce the torsional deformation of the empty box during the transition from tilted to vertical and back to tilted, ensuring the quality of the empty box. The first rotating shaft 2, the second rotating shaft 201, and the third rotating shaft 202 are all rotatably connected within the box. The first rotating shaft 2 and the second rotating shaft 201 are parallel to each other and located on either side of the third rotating shaft 202. Both the first rotating shaft 2 and the second rotating shaft 201 are spatially perpendicular to the third rotating shaft 202. At least two connecting shafts form a ring structure. Connecting belts 3, preferably two in number, with the distance between them less than the width of the empty box. The connecting surface between the two connecting belts 3 is the conveying surface, which facilitates the conveying of the empty box. The connecting belts 3 are sequentially mounted on the first rotating shaft 2, the third rotating shaft 202, and the second rotating shaft 201. The frame 1 is equipped with a motor for driving the third rotating shaft 202 to rotate. The motor is preferably a 120W micro motor. The cross-section of the connecting belts 3 is circular or elliptical. Here, we prefer a circular shape. In use, the twisting of the connecting belts 3 in the two sets of conveyor lines forms an approximately spiral-shaped conveying channel, which can achieve a 180° rotation of the empty box.

[0028] Reference Figures 1-4 A mounting bracket 102 is fixedly connected to the tabletop 101, and the first rotating shaft 2 and the second rotating shaft 201 are rotatably connected to the mounting bracket 102. The first rotating shaft 2 and the second rotating shaft 201 are distributed vertically. In use, by fixing the mounting bracket 102 to the tabletop 101, the first rotating shaft 2 and the second rotating shaft 201 can be supported and their reliable rotation can be ensured, thereby improving the use effect.

[0029] Reference Figure 1 , Figure 2 and Figure 4 A fan 4 is fixedly connected inside the frame 1. The fan 4 preferably has a power of 250W. An air outlet pipe 401 is fixedly connected inside the housing. The output end of the fan 4 is connected to the air outlet pipe 401 through a pipe. The outlet of the air outlet pipe 401 faces the point in the flipping conveyor section where the empty box changes from vertical to horizontal, that is, the point where the empty box changes from tilted to vertical to tilted. Especially when the height of the empty box is less than the width of the conveyor channel, it can reduce the possibility of the empty box falling at the turning point. In use, when the low-height empty box changes from vertical to tilted, although the empty box has a tendency to change due to the inertia of the conveyor line, the bottom of the empty box is briefly suspended at this time. At this time, the fan 4 is started, and the air outlet pipe 401 blows air onto the empty box, which can speed up the change in this process, reduce the suspension time, and make it smoothly change from vertical to tilted, ensuring the conveying and flipping effect of the low-height empty box.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
