Description

Technical Field

[0001] This invention relates to the field of fire protection equipment technology, specifically to an automatic opening device for packaging boxes used in fire protection equipment packaging. Background Technology

[0002] Firefighting equipment is a critical facility used for fire prevention, alarm, and extinguishing, as well as ensuring the safe evacuation of personnel. Packaging of firefighting equipment is a crucial step in ensuring that the equipment is not damaged and maintains stable performance during transportation, storage, and installation. Its packaging design must comprehensively consider the characteristics of the equipment (such as weight, size, and fragility), the transportation environment (such as vibration, humidity, and temperature), and safety regulations.

[0003] Packaging methods mainly include wooden crates, corrugated cardboard boxes, and metal frames. Among them, corrugated cardboard boxes are often used for packaging lightweight equipment (such as fire extinguishers and fire hoses) because of their low cost and recyclability.

[0004] During packaging in the workshop, flat corrugated cardboard boxes need to be folded and unfolded into packaging boxes before lightweight fire-fighting equipment is placed inside. Traditionally, this is done manually, but this method is inefficient and can easily damage the boxes during assembly. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of low efficiency and easy damage to packaging boxes during manual folding and unfolding. It provides an automatic unfolding device for packaging boxes for fire-fighting equipment, which can realize automatic forming of packaging boxes, improve efficiency, and prevent damage to packaging boxes.

[0006] The technical solution adopted by this invention to solve its technical problem is: An automatic opening device for packaging boxes for fire-fighting equipment includes a conveyor belt and a movable frame that can move back and forth. The conveyor belt is evenly provided with a plurality of forming grooves along the conveying direction. The movable frame is provided with a pressing mechanism for pressing flat packaging boxes into the forming grooves. The movable frame is provided with folding mechanisms on both sides of the forming grooves. The pressing mechanism includes a column mounted on the movable frame, a lifting frame mounted on the column and moving up and down on the column, and a pressure plate mounted on the lifting frame that cooperates with the forming groove. The movable frame is provided with a drive mechanism for driving the lifting frame to move up and down. The drive mechanism includes a motor mounted on the movable frame, a drive disk mounted on the output shaft of the motor, and a first connecting rod. The left end of the lifting frame is provided with a fixed shaft. The upper end of the first connecting rod is rotatably connected to the fixed shaft, and the lower end of the first connecting rod is rotatably connected to the drive disk at an eccentric position. When the motor drive shaft rotates, the movable frame moves back and forth under the action of the first linkage mechanism. The first linkage mechanism includes a drive shaft disposed within the movable frame and rotating within the movable frame, a turntable disposed on the drive shaft, a drive rod disposed at an eccentric position on the turntable, and a fixed block. The drive rod cooperates with the fixed block, and the motor output shaft is connected to the drive shaft via a belt. The folding mechanism includes a rotating rod mounted on the movable frame and rotating on the movable frame. The upper end of the rotating rod is provided with a stop bar that cooperates with the side plate in the height direction of the packaging box. The upper end of the rotating rod is provided with an arc-shaped plate that cooperates with the cover plate of the packaging box. When the lifting frame is raised and lowered, the rotating rod rotates under the action of the second linkage mechanism.

[0007] Furthermore, the upper end of the forming groove is provided with an outwardly curved arc-shaped portion.

[0008] Furthermore, two columns are arranged side by side.

[0009] Furthermore, a first guide rod is provided on the ground, and a guide sleeve that cooperates with the first guide rod is provided at the lower end of the movable frame. A tension spring is provided on the first guide rod, the front end of which is connected to the front end of the first guide rod, and the rear end of which is connected to the guide sleeve.

[0010] Furthermore, the side of the movable frame is provided with a bracket for supporting the motor.

[0011] Furthermore, the rotating rod is rotatably connected to the movable frame at its middle position.

[0012] Furthermore, the second linkage mechanism includes a lifting beam disposed within the movable frame and raised and lowered within the movable frame, a rotating rod rotatably connected to the column at its middle position, and second connecting rods disposed at the upper and lower ends of the rotating rod. The upper end of the second connecting rod is rotatably connected to the fixed shaft, the lower end of the second connecting rod is rotatably connected to the upper end of the rotating rod, the upper end of the second connecting rod is rotatably connected to the lower end of the rotating rod, and the lower end of the second connecting rod is rotatably connected to the lifting beam. The lifting beam is connected to the lower end of the rotating rod via a third connecting rod.

[0013] Furthermore, the movable frame is provided with a first through hole for the second connecting rod to pass through and a second through hole for the third connecting rod to pass through.

[0014] Furthermore, the movable frame is provided with a second guide rod that passes through the lifting beam and is slidably connected to the lifting beam.

[0015] The beneficial effects of this invention are: This invention includes a conveyor belt and a movable frame that can move back and forth. The conveyor belt has a plurality of forming grooves evenly distributed along the conveying direction. The movable frame is equipped with a pressing mechanism for pressing flat packaging boxes into the forming grooves. Folding mechanisms are located on both sides of the forming grooves on the movable frame. The conveyor belt continuously rotates backward, and a gripping mechanism picks up the unformed packaging boxes and places them at the pressing mechanism. The gripping mechanism can be a structure using a robotic arm in conjunction with suction cups. The pressing mechanism presses down, pressing the cardboard packaging box into the forming groove. During this process, the folding mechanism folds the side panels on both sides of the cardboard packaging box along its height direction; in layman's terms, this refers to the ear-shaped side panels on both sides of the packaging box. This achieves automatic forming of the packaging box, improves efficiency, and prevents damage to the packaging box.

[0016] The first linkage mechanism in this invention includes a drive shaft disposed within and rotating within the movable frame, a turntable disposed on the drive shaft, a drive rod disposed at an eccentric position on the turntable, and a fixing block. The drive rod cooperates with the fixing block, and the motor output shaft is connected to the drive shaft via a belt. When the motor output shaft rotates, the drive shaft rotates under the action of the belt, and the turntable rotates accordingly. Under the action of the drive rod and the fixing block, the movable frame moves continuously back and forth. When the lifting frame descends, the movable frame moves backward a short distance, coordinating with the backward movement of the conveyor belt to maintain synchronization. The conveyor belt does not need to stop operating to complete the folding and forming process, thus improving the forming efficiency. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0021] like Figure 1 As shown, an automatic opening device for packaging boxes for fire-fighting equipment includes a conveyor belt 1 and a movable frame 2 that can move back and forth. The conveyor belt 1 has several forming grooves 3 evenly distributed along the conveying direction. The movable frame 2 is equipped with a pressing mechanism for pressing flat packaging boxes into the forming grooves 3. Folding mechanisms are located on both sides of the forming grooves 3 on the movable frame 2, used to fold the side panels of the packaging box in the height direction. The conveyor belt continuously moves backward, and a gripping mechanism grips the unformed packaging box to the pressing mechanism. The gripping mechanism can be a structure using a robotic arm and suction cups, which is existing technology and will not be elaborated upon here. The pressing mechanism presses down the cardboard packaging box into the forming grooves 3, and during this process, in conjunction with the folding mechanism, folds the side panels of the cardboard packaging box in the height direction, which, in layman's terms, refers to the ear-shaped side panels on both sides of the packaging box. This achieves automatic forming of the packaging box, improves efficiency, and prevents damage to the packaging box.

[0022] like Figure 2 As shown, the pressing mechanism includes a column 4 mounted on the movable frame 2, a lifting frame 5 mounted on the column 4 and moving up and down on the column 4, and a pressure plate 6 mounted on the lifting frame 5 that cooperates with the forming groove 3. The movable frame 2 is provided with a drive mechanism for driving the lifting frame 5 to move up and down. When folding the packaging box, the drive mechanism drives the lifting frame 5 to move up and down. When the lifting frame 5 descends, the pressure plate 6 descends. The pressure plate 6 cooperates with the forming groove 3 to realize the folding and forming of the packaging box.

[0023] like Figure 2As shown, the driving mechanism includes a motor 7 mounted on the movable frame 2, a drive disc 8 mounted on the output shaft of the motor 7, and a first connecting rod 9. The left end of the lifting frame 5 is provided with a fixed shaft 10. The upper end of the first connecting rod 9 is rotatably connected to the fixed shaft 10, and the lower end of the first connecting rod 9 is rotatably connected to the drive disc 8 at an eccentric position. When the motor 7 drives the shaft to rotate, the movable frame moves back and forth under the action of the first linkage mechanism. The motor 7 drives the drive disc 8 to rotate, and under the action of the first connecting rod 9, the lifting frame 5 rises and falls on the column 4. The lifting frame 5 is driven to rise and fall through the drive disc 8 and the first connecting rod 9. The lifting height of the lifting frame 5 is fixed and highly accurate, and the packaging box will not be unable to be folded due to inconsistent lifting height.

[0024] like Figure 1 and Figure 2 As shown, the first linkage mechanism includes a drive shaft 11 disposed within and rotating within the movable frame 2, a turntable 12 disposed on the drive shaft 11, a drive rod 13 disposed at an eccentric position on the turntable 12, and a fixing block 14. The fixing block 14 is fixed to the ground. The drive rod 13 cooperates with the fixing block 14. The output shaft of the motor 7 is connected to the drive shaft 11 via a belt 15. Both the output shaft of the motor 7 and the drive shaft 11 are provided with pulleys that cooperate with the belt 15. When the output shaft of the motor 7 rotates, the drive shaft 11 rotates under the action of the belt 15, and the turntable 12 rotates accordingly. Under the action of the drive rod 13 and the fixing block 14, the movable frame 2 moves back and forth continuously. When the lifting frame 5 descends, the movable frame 2 moves backward a short distance, coordinating with the backward rotation of the conveyor belt 1 to maintain synchronization between the two. The conveyor belt 1 does not need to stop rotating to complete the folding and forming process, thereby improving the forming efficiency.

[0025] like Figure 1 and Figure 3 As shown, the folding mechanism includes a rotating rod 19 mounted on the movable frame 2 and rotating on the movable frame 2. The upper end of the rotating rod 19 is provided with a stop bar 20 that cooperates with the side plate in the height direction of the packaging box. The upper end of the rotating rod 19 is provided with an arc plate 21 that cooperates with the cover plate of the packaging box. When the lifting frame 5 is raised and lowered, the rotating rod 19 rotates under the action of the second linkage mechanism. When the lifting frame 5 is lowered, the rotating rod 19 rotates to a horizontal position under the action of the second linkage mechanism. At this time, the height of the stop bar 20 is higher than that of the arc plate 21. When the pressure plate presses down on the cardboard, the stop bar 20 contacts the side plate in the height direction of the cardboard, and the side plate folds. Then the arc plate 21 contacts the cover plate of the packaging box and pre-folds the cover plate to prevent the packaging box from being damaged due to the large size of the cover plate when the cardboard is folded in the forming groove 3.

[0026] like Figure 1 As shown, the upper end of the forming groove 3 is provided with an outwardly curved arc-shaped part to prevent scratching the packaging box.

[0027] like Figure 1 As shown, two columns 4 are arranged side by side to ensure the stability of the lifting frame. The columns pass through the lifting frame and are slidably connected to it.

[0028] like Figure 1 As shown, a first guide rod 16 is provided on the ground. A guide sleeve that cooperates with the first guide rod 16 is provided at the lower end of the movable frame 2. A tension spring 17 is provided on the first guide rod 16. The front end of the tension spring 17 is connected to the front end of the first guide rod 16, and the rear end of the tension spring 17 is connected to the guide sleeve. When the drive rod 13 and the fixed block 14 contact, the movable frame 2 moves backward a short distance against the elastic force of the tension spring 17. After the drive rod 13 and the fixed block 14 separate, the movable frame 2 moves forward and resets under the action of the elastic force of the tension spring 17. At this time, the movable frame 2 contacts the support plate at the front end of the first guide rod 13.

[0029] like Figure 2 As shown, the movable frame 2 has a bracket 18 on its side for supporting the motor 7.

[0030] The rotating rod 19 is rotatably connected to the movable frame 2 at its middle position.

[0031] like Figure 2 and Figure 3 As shown, the second linkage mechanism includes a lifting beam 22 disposed within the movable frame 2 and moving up and down within the movable frame 2, a rotating rod 23 rotatably connected to the column 4 at its middle position, and second connecting rods 24 disposed at the upper and lower ends of the rotating rod 23. The upper end of the upper connecting rod 24 is rotatably connected to the fixed shaft 10, and the lower end of the upper connecting rod 24 is rotatably connected to the upper end of the rotating rod 23. The upper end of the lower connecting rod 24 is rotatably connected to the lower end of the rotating rod 23, and the lower end of the lower connecting rod 24 is rotatably connected to the lifting beam 22. The lifting beam 22 is connected to the lower end of the rotating rod 19 via a third connecting rod 25. The upper end of the third connecting rod 25 is rotatably connected to the lower end of the rotating rod 19, and the lower end of the third connecting rod 25 is rotatably connected to the lifting beam 22. When the lifting frame 5 descends, the lifting beam 22 rises under the action of the second connecting rod 24 and the rotating rod 23. When the lifting beam 22 rises, one end of the inner side of the rotating rod 19 swings downward under the action of the third connecting rod 25.

[0032] like Figure 1 As shown, the movable frame 2 is provided with a first through hole 26 for the second connecting rod 24 to pass through and a second through hole 27 for the third connecting rod 25 to pass through.

[0033] like Figure 1 As shown, the movable frame 2 is provided with a second guide rod 28 that passes through the lifting beam 22 and is slidably connected to the lifting beam 22. The second guide rod 28 is in the vertical direction.
