Description

Technical Field

[0001] The utility model relates to the technical field of packaging box turning over, in particular to an automatic box turning over device for an in-line conveyor line. Background Art

[0002] In the process of packaging the products, usually the automatic packaging line is used for full-line automatic box loading and automatic 360° film wrapping. Because the film wrapping process requires that the film cutting interface must be at the bottom of the carton, and the carton output of the cartoning machine is in the upward direction, in order to meet the direction of the die-cutting interface of the film wrapping machine, the direction of the carton must be adjusted to meet the packaging requirements.

[0003] The traditional box turning operation usually requires an additional worker to turn the boxes manually at the production site, which not only increases the labor cost but also reduces production efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the position and direction of the packaging box in the original packaging line design cannot meet the requirements of automatic packaging, resulting in a reduction in processing efficiency.

[0005] In order to solve the above problems, the technical solution of the utility model is: an automatic box turning device of an in-line conveyor line, comprising a frame and a conveyor belt on the frame, a first stopper is provided at both ends of the top surface of the frame along the width direction of the conveyor belt, and a first force point is formed at the contact point between the end of the first stopper and the packaging box;

[0006] An inverted U-shaped frame is provided on the frame in the conveying direction of the conveyor belt along its width direction, and a second stopper extending toward the first stopper is provided in the middle position of the U-shaped frame, and the second stopper is an upwardly bent arc hook structure, and a second force point is formed at the contact point between the second stopper and the packaging box, and the first stopper and the U-shaped frame are elastic parts.

[0007] Furthermore, the first force point is 2-5mm lower than the upper edge of the current flipped packaging box, the second force point is 2-5mm lower than the upper edge of the current flipped packaging box, the length of the second stopper is 2-5mm longer than the length of the last flipped packaging box surface, and the height of the second stopper is 2-5mm lower than the height of the current flipped packaging box surface, and the distance between the second stopper and the conveyor belt is determined by the current height of the flipped packaging box, and the height is 2-5mm less than the current height of the flipped packaging box.

[0008] Furthermore, limiting plates are provided on the top surface of the frame at both ends of the conveyor belt along its length direction.

[0009] Furthermore, the bottom surfaces at both ends of the first stopper are respectively provided with connecting seats and the first positioning hole is opened on the connecting seats, and the bottom surfaces at both ends of the U-shaped frame are respectively provided with mounting seats and the second positioning hole is opened on the mounting seats.

[0010] Furthermore, an anti-wear sleeve is provided on the outer side of the second stopper.

[0011] The advantage of the utility model compared with the existing technology is that: through the cooperation of the first stopper, the U-shaped frame and the second stopper, when the packaging box is transported and waits for the packaging box to run to the device, a first force is applied to it to make it flip 90 degrees. After the packaging box passes through the first force, a second force is applied to make it flip 180 degrees again, so that it can reach the expected position. During use, the force points and the straight track are fully utilized to operate at a uniform speed to turn the packaging box, thereby meeting the requirements of the die-cutting interface direction of the longitudinal film wrapping machine in the back-end process.

[0016] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0017] like Figure 1 to Figure 2 As shown, the in-line conveyor line automatic box turning device comprises a frame 1 and a conveyor belt 2 on the frame 1, first stoppers 4 are provided at both ends of the top surface of the frame 1 along the width direction of the conveyor belt 2, and a first force point 5 is formed at the contact point between the end of the first stopper 4 and the packaging box 3, and the packaging box 3 can be turned 90 degrees through the first force point 5 during the conveying process of the packaging box 3;

[0018] An inverted U-shaped frame 6 is provided along the width direction of the frame 1 in the transmission direction of the conveyor belt 2, and a second stopper 7 extending toward the first stopper 4 is provided in the middle position of the U-shaped frame 6, and the second stopper 7 is an upwardly curved hook structure, and an anti-wear sleeve is sleeved on the outer side of the second stopper 7, and a second force point 8 is formed at the contact between the second stopper 7 and the packaging box 3. Under the action of the second force point 8 and the second stopper 7, the packaging box 3 can be turned over 180 degrees again. The first stopper 4 and the U-shaped frame 6 are elastic parts, and they must also have the characteristics of wear resistance and non-deformation.

[0019] The first force point 5 is 2-5mm lower than the upper edge of the current flipped packaging box 3, the second force point 8 is 2-5mm lower than the upper edge of the current flipped packaging box 3, the length of the second stopper 7 is 2-5mm greater than the length of the surface of the last flipped packaging box 3, and the height of the second stopper 7 is 2-5mm lower than the height of the surface of the current flipped packaging box 3, the distance between the second stopper 7 and the conveyor belt 2 is determined by the current height of the flipped packaging box 3, and the height is 2-5mm less than the current height of the flipped packaging box 3;

[0020] By limiting the specific positions of the first force point 5, the second force point 8 and the second stopper 7 with respect to the flip packaging box 3, and limiting the position between the second stopper 7 and the conveyor belt 2 through the above structure, the flip packaging box 3 can be effectively adjusted during the conveying process.
