[0001] The utility model relates to the field of cartoning machines, in particular to a compression carrier.

[0002] The utility model also relates to a cartoning machine. Background Art

[0003] Soft packaging materials such as stick packs, three-side sealed and four-side sealed pouches are relatively soft. When the existing cartoning machines pack the soft packaging materials into boxes, they need to compress the packaging materials first and then pack them into boxes, so as to make full use of the limited space inside the packaging box. Figure 1 The schematic diagram of the existing cartoning machine for packing packages is presented. Figure 1 , the existing cartoning machines include:

[0004] The carrier 1 has a compression groove 11 formed on the top thereof, the compression groove 11 is used to place the package 14 and can guide the package 14 to move toward the packaging box 13, and the compression groove 11 includes two ends with different widths, wherein the width of one end is greater than the outer width of the package 14, and the width of the other end is less than the inner width of the packaging box 13;

[0005] The push handle 12 is disposed on the opposite side of the packaging box 13 relative to the carrier 1 and is used to push the packaging 14 to move along the compression groove 11 to the inside of the packaging box 13 so that the outer width of the packaging 14 is compressed to a size smaller than the inner width of the packaging box 13 .

[0006] Combination Figure 1 The defect of the existing cartoning machine is that the width of the push handle 12 cannot be greater than the width of the compression groove 11, which causes the corners of the package 14 to overflow between the push handle 12 and the compression groove 11. When the package 14 is pushed by the push handle 12, the corners of the package 14 are easily stuck in the gap between the side wall of the push handle 12 and the side wall of the compression groove 11, thereby causing the package 14 to be torn.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] The following provides a compression carrier for a cartoning machine, which aims to solve the problem that when a package 14 with an outer width larger than the inner width of the package 13 is loaded into the package 13 by the existing cartoning machine, the package 14 is easily damaged.

[0037] Figure 2 The improved compression carrier box loading action diagram is presented, combined with Figure 2 .

[0038] The compression carrier includes:

[0039] The bearing portion 2 comprises a bottom wall and a first side wall erected on one side of the bottom wall;

[0040] The compression part 3 is slidably connected to the bearing part 2 and has a second side wall standing upright on the other side of the bottom wall.

[0041] The working principle of the compression carrier is: the package 14 is placed on the bottom wall and clamped by the first side wall and the second side wall. When the second side wall moves toward the first side wall, the package 14 is compressed, and then the push handle 12 pushes the compressed package 14 into the interior of the packaging box 13.

[0042] Through the above working principle, before the package 14 is pushed by the push handle 12 , the outer width of the package 14 has been compressed to a size that fits the push handle 12 , thereby avoiding the problem of the corners of the package 14 overflowing from both ends of the push handle 12 .

[0043] (First embodiment)

[0044] Figures 3 to 8 The specific structure of the compression carrier is shown, wherein: Figure 3 A three-dimensional image of the compression carrier is shown. Figure 4 A front view of the partial structure of the compression carrier is shown. Figure 5 A bottom view of the partial structure of the compression carrier is shown. Figure 5 A three-dimensional diagram of the local structure of the compression carrier is shown, combined with Figure 3 , Figure 4 , Figure 5 , Figure 6 .

[0045] The compression carrier includes:

[0046] The bearing part 2 is movably connected to the frame and comprises a bottom wall and a first side wall erected on one side of the bottom wall;

[0047] The compression part 3 is slidably connected to the bearing part 2 and has a second side wall erected on the other side of the bottom wall;

[0048] The rotating part 4 is rotatably connected to the bearing part 2;

[0049] The first cam mechanism 5 is transmission-connected to the frame and the rotating part 4, and causes the rotating part 4 to perform a rotational motion through the linear motion of the bearing part 2;

[0050] The second cam mechanism 6 is transmission-connected to the rotating part 4 and the compression part 3. The rotational movement of the rotating part 4 causes the compression part 3 to perform linear movement, thereby causing the second side wall to approach the first side wall to compress the package 14 placed on the bottom wall.

[0051] The working principle of the compression carrier is:

[0052] The load-bearing portion 2 is usually installed on a conveyor, which is used to transport the load-bearing portion 2 through a loading station and a packaging station. The package 14 moves to the bottom wall of the load-bearing portion 2 at the loading station and is clamped in the middle by the first side wall and the second side wall. Then the load-bearing portion 2, the compression portion 3 and the package 14 move toward the packaging station together. During the movement of the load-bearing portion 2 from the loading station to the packaging station, the linear movement of the load-bearing portion 2 itself is transmitted to the compression portion 3 through the first cam mechanism 5 and the second cam mechanism 6, so that the second side wall approaches the first side wall, thereby compressing the package 14. The compressed package 14 is pushed to the inside of the packaging box 13 by the pusher 12 at the packaging station. After the load-bearing portion 2 leaves the packaging station, the second side wall moves away from the first side wall, so that the compression portion 3 is reset.
