[0001] The utility model belongs to the technical field of machinery and relates to a flower packaging machine, in particular to a carrier for the flower packaging machine. Background Art

[0002] In the past, flowers were packaged manually, which was inefficient. Therefore, people designed various machines that can realize automatic packaging of flowers, and some have even applied for patents.

[0003] For example, Chinese patent literature discloses a multifunctional bundling and packaging device for fresh cut flowers [application number: 202220182004.6; authorization announcement number: CN216995005U], which consists of a flower branch conveying device, a flower branch picking device, an outer packaging material taking and placing device, a tooling conveying device, a flower wrapping clamp tooling, a flower branch bundling device, and a residual branch cutting and collecting device. The flower wrapping clamp tooling consists of a tooling frame, a lifting rod, a clamping plate, a pressure rod, a buffer device, a clamping device, a centering device and a folding cover plate. The tooling frame has a symmetrical structure, and lifting rods are respectively arranged on it. Clamping plates are arranged between the tooling frames through the centering device and the buffer device. A folding cover plate and a pressure rod are arranged on the upper part of the clamping plate through a hinge, and a clamping device is also arranged between the bottom of the tooling frames.

[0004] The flower wrapping clamp tooling in the above-mentioned multifunctional bundling and packaging device for fresh cut flowers can be used to place outer packaging materials, inner partitions and flower branch groups, but its structure is complex and the manufacturing cost is high. Moreover, when in use, the outer packaging expansion rod presses the two sides of the outer packaging material, and the mouth of the tooling frame and the outer packaging material cannot expand outward. Because the flower branch group is composed of multiple fresh flowers, and the sizes of fresh flowers are different, there is a situation where the expanded size of the flower branch group is larger than the size of the mouth of the tooling frame designed for the flowers to be placed in. This makes it difficult to put the flower branch group in, and there is also the problem of the tooling frame damaging the flowers, affecting the packaging quality. Summary of the invention

[0005] The utility model aims to solve the above problems in the prior art and provide a carrier for a flower packaging machine which can prevent flowers from being damaged.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a carrier for a flower packaging machine, comprising a bottom plate, characterized in that the bottom plate is hinged with two oppositely arranged side plates, the bottom plate is fixedly connected with a back plate, the back plate and the two side plates surround a placement cavity with front end and top end openings, the bottom plate or the back plate is provided with abutment portion 1 and abutment portion 2 for the two side plates to abut, when the two side plates abut against the abutment portion 1, the two side plates are vertically opposite to each other, when the two side plates abut against the abutment portion 2, the two side plates rotate around the hinge and the top ends of the two side plates expand to both sides, and the bottom plate or the back plate is provided with an elastic structure that provides elastic force to keep the two side plates vertically opposite to each other.

[0007] In the above-mentioned carrier for a flower packaging machine, the bottom plate is fixedly connected with two fixing blocks, and the fixing blocks are hinged to the corresponding side plates through hinges.

[0008] In the above-mentioned carrier for a flower packaging machine, the back plate is provided with two horizontally arranged waist-shaped holes, and the two side plates are fixedly connected with pins extending into the corresponding waist-shaped holes, the width of the waist-shaped holes is greater than the diameter of the pins, and the abutment part 1 is two blocks fixedly connected to the back plate, and the two blocks are vertically superimposed on the corresponding waist-shaped holes respectively, and the abutment part 2 is the hole wall of the two waist-shaped holes close to the side wall of the back plate.

[0009] In the above-mentioned carrier for a flower packaging machine, the elastic structure includes two horizontally arranged displacement rods, and a plurality of guide blocks for the two displacement rods to pass through are fixedly connected to the back plate. The two displacement rods have vertically arranged strip holes for the corresponding pin shafts to pass through, and the two displacement rods are both sleeved with springs that provide elastic force so that the pin shafts maintain a tendency to abut against the abutment portion.

[0010] In the above-mentioned carrier for a flower packaging machine, a bolt is passed through the inner end of the displacement rod, and a nut is threadedly connected to the bolt.

[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the carrier for the flower packaging machine includes a bottom plate 1, which is hinged with two oppositely arranged side plates 2, and the bottom plate 1 is fixedly connected with a back plate 3. The back plate 3 and the two side plates 2 form a placement cavity with openings at the front end and the top end. The bottom plate 1 or the back plate 3 is provided with abutment portion 1 4 and abutment portion 2 5 for the two side plates 2 to abut against. When the two side plates 2 abut against the abutment portion 1 4, the two side plates 2 are vertically opposite to each other. When the two side plates 2 abut against the abutment portion 2 5, the two side plates 2 rotate around the hinge and the top ends of the two side plates 2 expand to both sides. The bottom plate 1 or the back plate 3 is provided with an elastic structure that provides elastic force to keep the two side plates 2 vertically opposite to each other.

[0019] When the carrier of the flower packaging machine is in use, the manipulator clamps a plurality of flowers, and the manipulator moves down to contact the two side plates 2, overcoming the elastic force of the elastic structure so that the top ends of the two side plates 2 expand to the sides. In this way, even if the flowers on the manipulator expand outward due to their size, the two side plates 2 with the expanded top ends provide sufficient space for placement, and the two side plates 2 will not damage the flowers. The process of placing the flowers into the placement cavity is smooth, and then the manipulator withdraws, and the elastic structure provides elastic force to keep the two side plates 2 vertically opposite to each other; when the two side plates 2 are reset, because the flowers in the placement cavity are not clamped by the manipulator, the flowers on the two sides can be gathered to the middle by the force of the two side plates 2, and the two side plates 2 will not damage the flowers, thereby improving the packaging quality.

[0020] In further detail, the bottom plate 1 is fixedly connected with two fixing blocks 6, and the fixing blocks 6 are hingedly connected to the corresponding side plates 2 through hinges 7. The fixing blocks 6 play a lifting role to avoid interference, and the side plates 2 rotate smoothly with the hinges 7.

[0021] In this embodiment, the back plate 3 is provided with two horizontally arranged waist-shaped holes 8, and the two side plates 2 are fixedly connected with pin shafts 9 extending into the corresponding waist-shaped holes 8. The width of the waist-shaped hole 8 is greater than the diameter of the pin shaft 9. The abutment part 1 4 is two stoppers 10 fixedly connected to the back plate 3, and the two stoppers 10 are vertically overlapped on the corresponding waist-shaped holes 8 respectively. The abutment part 2 5 is the hole wall of the two waist-shaped holes 8 close to the side wall of the back plate 3.

[0022] When in use, when the pin shafts 9 of the two side plates 2 abut against the corresponding stop blocks 10, the two side plates 2 are vertically opposite to each other. In this embodiment, the stop blocks 10 are fixed to the back plate 3 by screws. The setting of the stop blocks 10 enables the two side plates 2 to be accurately positioned; when the pin shafts 9 of the two side plates 2 respectively abut against the hole walls of the corresponding waist-shaped holes 8 close to the side walls of the back plate 3, the top ends of the two side plates 2 expand to both sides. Because the width of the waist-shaped hole 8 is greater than the diameter of the pin shaft 9, the upper and lower hole walls of the waist-shaped hole 8 will not interfere with the pin shaft 9, and the outward expansion of the side plates 2 drives the pin shaft 9 to move smoothly.

[0023] The elastic structure includes two horizontally arranged displacement rods 11, and four guide blocks 12 for the two displacement rods 11 to pass through are fixedly connected to the back plate 3. The two displacement rods 11 have vertically arranged strip holes 13 for the corresponding pin shafts 9 to pass through. The two displacement rods 11 are both sleeved with springs 14 that provide elastic force to keep the pin shaft 9 in contact with the abutment portion 4.

[0024] The spring 14 provides elastic force to keep the pin shaft 9 in contact with the abutment part 4, so that the two side plates 2 remain in a vertically relative state. The two side plates 2 are subjected to force to overcome the elastic force of the spring 14, and the top ends of the two side plates 2 expand outward. The strip hole 13 will not interfere with the displacement of the pin shaft 9, and the working process is smooth. In this embodiment, the displacement rod 11 has a shoulder for one end of the spring 14 to abut, and the other end of the spring 14 abuts on the guide block 12. This structure is simple and easy to arrange.

[0025] The inner end of the displacement rod 11 is provided with a bolt 15, and the bolt 15 is threadedly connected with a nut 16. The bolt 15 and the nut 16 not only play a counterweight role, but also are convenient for workers to grasp and are convenient for the assembly of the spring 14.
