Description

Technical Field

[0001] This utility model belongs to the field of logistics packaging carrier technology, specifically relating to a small roll material storage and transfer recycling packaging box. Background Technology

[0002] For the transportation and line-side use of industrial roll materials such as aluminum foil rolls, fiberglass rolls, fabric rolls, and film rolls, it is necessary to consider core requirements such as deformation prevention, moisture prevention, pollution prevention, and friction resistance. Traditional cardboard boxes or wooden boxes are prone to the following defects: First, the side wall support of the box is insufficient, and the lower layer of roll material is subjected to excessive pressure when stacked, causing the core shaft to deform and the edges to collapse, resulting in the material being unable to unwind properly; Second, the packaging material is in direct contact with the surface of the roll material, which is prone to surface contamination and scratches; Third, the moisture-proof performance of the box is insufficient. In environments with high air humidity, it is impossible to prevent the roll material from getting damp. Aluminum foil will oxidize and produce white spots when damp, and the strength of fiberglass will decrease significantly after absorbing moisture, affecting the performance of the roll material.

[0003] Patent application number 2024202128244 discloses a packaging box for roll material packaging. It uses a side panel and a bottom support to form a receiving cavity, and a notch is set on the side panel to support the end of the mandrel. In order to facilitate opening and closing, multiple movable plates are set on the box body. Although the packaging box can be used to store and transport roll material, it can only hold one roll material. Moreover, if the weight of the roll material is too large, the plastic packaging box may be damaged due to exceeding the bearing limit, and the internal roll material may also be deformed. Setting too many movable plates will result in too many gaps on the box body, affecting the moisture-proof performance.

[0004] Among the existing improvement solutions, steel-edged boxes are used for transportation. However, this is not only costly and heavy, but also inconvenient to store and cannot be used in conjunction with lined boxes. Therefore, it is necessary to improve the design of existing packaging boxes. Utility Model Content

[0005] To address the aforementioned problems and technical needs, this utility model provides a small roll material storage and transfer recycling packaging box. The box body is made by combining a steel frame with a plastic outer layer, which provides high support strength for the roll material while being lightweight. Furthermore, the box can accommodate multiple roll materials at the same time, and the roll materials also have good limiting and anti-jumping effects, making it suitable for the transportation of small roll materials and for use at the edge of the production line.

[0006] The technical solution of this utility model is as follows: A small roll material storage and transfer recycling packaging box includes a top cover plate, a side plate, a bottom support plate, a limiting steel frame, and a support frame. The side plate is inserted into the four sides of the bottom support plate, and the limiting steel frame is provided inside the side plate. The limiting steel frame is connected to the bottom support plate, and the top cover plate covers the top of the side plate. The limiting steel frame includes a bottom horizontal frame, a side vertical frame, and guide horizontal columns. The side vertical frame is fixedly connected to one side of the bottom horizontal frame. The bottom horizontal frame and the side vertical frame are symmetrically provided with supporting diagonal rods on both sides. Multiple guide horizontal columns are vertically connected to the inner side of the side vertical frame. The guide horizontal columns extend parallel to the bottom horizontal frame to the opposite side. Multiple roll material workpieces can be fitted onto the guide horizontal columns. The center of the end face of the guide horizontal column is provided with an insertion shaft. The support frame is detachably connected to the other side of the bottom horizontal frame. The support frame is provided with insertion holes. The insertion shaft and the insertion holes are correspondingly inserted. The guide horizontal columns can support the roll material workpieces independently or cooperate with the support frame to support the roll material workpieces.

[0007] Compared to wooden and plastic boxes, the limiting steel frame has higher strength and can support multiple rolls of material, preventing deformation and loss caused by pressure and friction between the rolls. The supporting diagonal bars reinforce the limiting steel frame on both sides to prevent deformation during use. When working on the line, the support frame can be removed for easy access to the rolls. During packing and transportation, the support frame is fixedly connected to the bottom crossbar to ensure stability during transportation. The support frame supports the guide crossbar at the other end, providing better limiting and anti-jumping effects.

[0008] Furthermore, the guide column is provided with multiple limiting pin holes along its length. These holes penetrate vertically through the guide column, and each hole can accommodate a positioning pin. The positioning pins limit the end face of the roll material fitted onto the guide column. Since multiple roll materials are fitted onto one guide column, when using the line edge, after removing one roll material, the next roll material must be secured to prevent it from rolling or slipping. Depending on the placement position of the roll material, inserting the positioning pins into the limiting pin holes limits the roll material, preventing slippage and improving safety.

[0009] Furthermore, a flange seat is provided at the connection between the guide column and the side vertical frame. Multiple triangular reinforcing ribs are welded between the flange seat and the guide column. A ring of mounting holes is provided on the flange seat, and the flange seat and the side vertical frame are locked together through the mounting holes.

[0010] Furthermore, a fixed circular step is provided on the outer end face of the guide column. The fixed circular step is fixed around the outside of the insertion shaft. A limiting sleeve is detachably fitted on the outside of the fixed circular step. The limiting sleeve can press the mandrel end face of the outermost roll material.

[0011] Furthermore, the positioning pin is cylindrical, with a spherical head that is larger than the diameter of the positioning pin, and an external thread at the tail. The circumferential surface of the limiting sleeve has multiple screw holes that are distributed at equal angles along the circumference, and the tail of the positioning pin can be screwed into the screw holes.

[0012] A limiting sleeve is fitted onto the outer end of the guide column to tighten the roll material and prevent axial collisions during transportation due to excessive gaps between roll materials. Multiple screw holes on the outside of the limiting sleeve can be used to store positioning pins. This way, a positioning pin can be unscrewed from the limiting sleeve whenever needed. Excess positioning pins do not need to be specially stored, which facilitates the management of positioning pins and improves the convenience and flexibility of use.

[0013] Furthermore, the base plate is made of double-layer vacuum-formed material, and a reinforcing steel frame is provided on the bottom surface of the base plate. The reinforcing steel frame, the base plate, and the bottom crossbar are connected by multiple bolts. Both the reinforcing steel frame and the bottom crossbar are made of steel, and they clamp and fix the base plate in the middle, which can prevent the plastic base plate from deforming and improve the support strength of the bottom.

[0014] Furthermore, a guide slot is provided near the edge of the outer side of the bottom cross frame. The guide slot consists of two symmetrically arranged L-shaped plates. The L-shaped plates are fixedly connected to the bottom cross frame by screws. The L-shaped plates are provided with fixing holes. The bottom of the support frame is provided with an insert plate. The insert plate can be inserted into the guide slot from the outside to the inside. The insert plate is provided with holes corresponding to the fixing holes. The L-shaped plates, insert plates and bottom cross frame are locked together by screws.

[0015] Furthermore, the outer side of the bottom cross frame is provided with multiple sets of guide slots, and a support frame is inserted into each guide slot. The support frame is a hollow square steel tube, and multiple insertion holes are provided along the support frame. Each insertion hole corresponds to the insertion of a guide cross column. Reinforcing ribs are provided between the support frame and the bottom insertion plate.

[0016] Furthermore, both the top cover and the surrounding panels are made of plastic.

[0017] The beneficial effects of this utility model are:

[0018] 1) This packaging box uses a combination of an outer plastic box and an internal limiting steel frame to store and package industrial roll materials. The internal limiting steel frame has high strength and can support multiple roll materials. It is not easily deformed during use, and the roll materials will not be deformed due to mutual friction or stacking, thus providing excellent protection for the roll materials. The outer plastic box is not only lightweight, which greatly reduces the weight of the box, but also has good moisture-proof performance. It is also very convenient to unpack. Just remove the top cover and the side panels, and it can be used at the production line, meeting the needs of various working conditions.

[0019] 2) The guide columns on the limiting steel frame can independently support and fix the roll material. The tail of the guide column is equipped with a flange seat. The flange seat is reinforced with triangular ribs to greatly improve the strength of the connection, avoid bending when supporting multiple roll materials, and keep the guide column in a horizontal support state. The flange seat and the side vertical frame are detachably connected, and can be quickly replaced when the guide column is damaged. A row of limiting pin holes along the axial direction can fix the roll material axially with the cooperation of the positioning pin, preventing the roll material from slipping off the guide column when bumping, and ensuring safety in use.

[0020] 3) A detachable support frame is installed on one side of the limiting steel frame, which can be used for two working conditions. In the case of use at the line edge, the detachable support frame allows workers to easily take the roll material from the guide column, improving work efficiency. In the case of long-distance packing and transportation, the support frame can enhance the support and stability of the roll material, prevent the roll material from jumping, and at the same time reduce the pressure on the other side of the guide column, protect the guide column, and prevent the roll material from axial movement when shaking and bumping, thus improving transportation safety.

[0021] 4) This box can be reused multiple times and after its effective service life, it can be recycled and reused, realizing green recycling of packaging, without generating pollution, and is highly environmentally friendly. Attached Figure Description
