Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to a top and bottom cover gluing and forming machine. Background Technology

[0002] In the modern packaging industry, the manufacturing process of fruit storage boxes is gradually moving towards automation and efficiency. Currently, most common fruit storage boxes use a top-and-bottom lid structure, with symmetrical and similar shapes for the top and bottom lids. In traditional production processes, manual application of glue to the four corners of the cardboard and manual folding are required to complete the shaping. This manual operation is not only inefficient but also requires at least two workstations working together, significantly increasing labor costs. Furthermore, with the increasing market demand for fruit boxes, traditional manual production methods can no longer meet the requirements of large-scale, high-efficiency production. Therefore, there is an urgent need for automated equipment that can replace manual operation to improve production efficiency.

[0003] While existing automated folding box equipment can improve production efficiency to some extent, it still has many shortcomings. For example, the coordination and intelligence of the equipment are low in the paperboard feeding, gluing, folding, and forming processes, resulting in limited overall production efficiency. Especially in the paperboard feeding process, due to the diverse sizes of the paperboard and its tendency to shift positions, existing equipment often struggles to achieve precise feeding, thus affecting subsequent gluing and folding processes. Furthermore, the gluing devices and forming mechanisms in existing equipment lack flexibility and cannot quickly adapt to the processing needs of different sized paperboards, further limiting the equipment's applicability. At the same time, the loading and feeding operations of traditional equipment are complex and time-consuming, making it difficult to meet the needs of mass production.

[0004] To address the aforementioned issues, developing an automated box-making machine capable of efficient feeding, precise gluing, rapid folding, and flexible forming is of great significance. This equipment needs intelligent control capabilities, automatically adjusting the feeding spacing based on the cardboard dimensions, and achieving rapid and stable box production through efficient gluing and forming mechanisms. Furthermore, the feeding mechanism should be designed with short-stroke operations to minimize time loss, while the conveying mechanism must ensure the stability of the cardboard during transport, preventing interference and misalignment. These improvements can significantly enhance the production efficiency of fruit boxes, meeting the demands of large-scale production, while simultaneously reducing labor costs and improving the product's market competitiveness.

[0063] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings:

[0064] Top and bottom cover gluing and molding machine, combined with attached Figure 1 To be continued Figure 4 The specific embodiments of this utility model will be described in detail. Figure 1 This is a schematic diagram of the overall structure of this utility model. Figure 2 A detailed schematic diagram showing the parts delivered to the receiving and loading mechanisms. Figure 3 This is a schematic diagram of the feeding device and forming mechanism. Figure 4 Further details of the forming mechanism are shown below. All parts mentioned in the following description correspond to the markings in the accompanying drawings.

[0065] The core of this invention lies in achieving fully automated operation of cardboard from feeding, gluing, pushing to folding through the coordinated work of multiple mechanisms, significantly improving production efficiency and reducing manual intervention. The equipment includes a feeding mechanism 1, a forming mechanism 2, a feeding device 3, and a loading mechanism 4, all mounted on a frame. These mechanisms work closely together in actual operation to complete the entire processing from raw cardboard to finished fruit boxes.

[0066] The feeding mechanism 1 is the foundation of the entire equipment. Its main function is to place the cardboard to be formed and push it to the forming mechanism 2. The feeding mechanism 1 includes a pair of feeding slides 9, a hopper, a material support pulley 7, a sliding hanging plate 12, an adjusting screw 13, a glue gun 17, and a glue dispensing sensor 19. The hopper consists of a pair of hopper plates 6 fixedly mounted on the feeding slides 9 and a rear hopper plate 8 slidably mounted on the frame. The rear hopper plate 8 is slidably connected to the frame via a rear hopper plate moving seat 10, which is threadedly connected to a rear hopper plate screw 11. When it is necessary to adjust the width of the hopper to accommodate cardboard of different sizes, rotating the rear hopper plate screw 11 will move the rear hopper plate 8 back and forth along the frame, thereby changing the size of the hopper. Positioning grooves 15 are provided near the bottom of the hopper plates 6 and the rear hopper plate 8, and the material support pulley 7 is rotatably mounted in the positioning grooves 15. The function of the material support pulley 7 is to hold the placed cardboard in place, preventing it from slipping or shifting during the feeding process. Additionally, the sliding hanger 12 is slidably mounted on the guide rod 16 via bearings, used to adjust the position of the feeding slide rail 9. The adjusting screw 13 cooperates with the adjusting threaded seat 14 to control the spacing between the pair of feeding slide rails 9, thus meeting the processing requirements of cardboard of different specifications.

[0067] The feeding mechanism 1 also includes a glue gun 17 and a dispensing sensor 19. The glue gun 17 is positioned on one side of the feeding slide rail 9 and is used for dispensing glue onto the cardboard. A stopper 18 is installed on one side of the glue gun 17, and the dispensing action is controlled by starting and stopping the stopper 18. The dispensing sensor 19 detects the cardboard that has slid across the material guide 20 and transmits a signal to the controller, which then controls the glue gun 17 to perform the dispensing operation based on the signal. This design ensures the accuracy of the dispensing action and avoids wasting glue or missing glue.

[0068] The feeding mechanism 4 is a key component of the equipment, responsible for adsorbing and pulling the cardboard from the hopper onto the receiving guide 20. The feeding mechanism 4 includes a cylinder mounting base 31, a lifting cylinder 30, a lifting bracket 29, and multiple suction cups 21. The cylinder mounting base 31 is fixed to the frame and is used to mount the lifting cylinder 30. The piston rod of the lifting cylinder 30 is fixedly connected to the lifting bracket 29, and multiple suction cups 21 are mounted on the top of the lifting bracket 29. The suction cups 21 adsorb the cardboard through negative pressure, completing a short-stroke pull-down action and stably placing the cardboard onto the receiving guide 20. This process not only improves the efficiency of cardboard feeding but also ensures the positional accuracy of the cardboard on the receiving guide 20. The lifting bracket 29 slides on the cylinder mounting base 31, allowing it to slide up and down relative to the cylinder mounting base 31, while the lifting cylinder 30 controls the lifting and lowering of the lifting bracket 29 relative to the cylinder mounting base 31.

[0069] The feeding device 3 includes a feeding linear module 24, an anti-interference cylinder 23, and an L-shaped pusher plate 22. The feeding linear module 24 is fixed to the frame, and the output end of the linear module 24 is connected to the anti-interference cylinder 23. The linear module 24 controls the anti-interference cylinder 23 to move horizontally. The L-shaped pusher plate 22 is fixedly mounted on the top of the piston rod of the anti-interference cylinder 23. The anti-interference cylinder 23 controls the raising and lowering of the L-shaped pusher plate 22 to prevent interference between the L-shaped pusher plate 22 and the cardboard placed on the feeding mechanism 1 during the resetting process. The L-shaped pusher plate 22 is used to abut against the cardboard placed on the receiving guide 20 and quickly push the cardboard to the forming mechanism 2. This design effectively shortens the cardboard pushing time and improves the overall production efficiency.

[0070] The forming mechanism 2 is the core component of the equipment, used to fold and glue the cardboard to complete the final forming operation. The forming mechanism 2 includes a forming drive module 25, a forming lower pressure plate 26, a left-right adjustable base plate 28, a front-back adjustable plate 33, a stamping assembly 32, and forming sheet metal assemblies 27. The left-right adjustable base plate 28 and the front-back adjustable plate 33 can control the spacing between the various sheet metal assemblies 27. Both the left-right adjustable base plate 28 and the front-back adjustable plate 33 are equipped with screws and threaded seats to control their movement. Specifically, the left-right adjustable base plate 28 slides on the frame, while the front-back adjustable plate 33 slides on the left-right adjustable base plate 28. The stamping assembly 32 is mounted on the front-back adjustable plate 33, and multiple forming sheet metal assemblies 27 are fixedly mounted on the front-back adjustable plate 33. The drive module 25 can control the vertical movement of the forming lower pressure plate 26.

[0071] The following is the specific structure of the molding drive module 25:

[0072] The forming drive module 25 includes a lifting pressure plate 35 that slides on the frame and moves up and down. A forming lower pressure plate 26 is fixedly installed at the bottom of the lifting pressure plate 35. The lifting pressure plate 35 is guided by guide rails to limit its sliding direction and trajectory, ensuring smooth movement. Pressure rods 34 are provided on both sides of the lifting pressure plate 35. The pressure rods 34 are rotatably connected to the lifting pressure plate 35 near the forming lower pressure plate 26, and the top of the pressure rods 34 is rotatably connected to a connecting rod 36. The other end of the connecting rod 36 is fixedly connected to a drive shaft 37. The drive shaft 37 is rotatably connected to the frame through a bearing seat. A drive motor 38 is fixedly installed on the frame, and the output end of the drive motor 38 is connected to one end of the drive shaft 37. The drive motor 38 controls the movement of the connecting rod 36 by rotating the drive shaft 37, thereby driving the lifting pressure plate 35 to slide vertically, realizing the folding and forming of the cardboard.

[0073] The left and right adjustable base plate 28 is slidably mounted on the frame and is used to adjust the position of the front and rear adjustable plates 33. The front and rear adjustable plates 33 are fixedly equipped with a stamping assembly 32 and a forming sheet metal assembly 27. The forming sheet metal assembly 27 can fold and form the cardboard sequentially, while the stamping assembly 32 further folds and presses the cardboard box to prevent accidental unfolding. An opening is provided in the middle of the forming sheet metal assembly 27. The stamping assembly 32 includes a telescopic and translatable pressure plate that passes through the opening into the forming sheet metal assembly 27 to press the cardboard box during forming, ensuring precise and secure folding angles. Multiple forming sheet metal assemblies 27 mounted on the front and rear adjustable plates 33 can change position by moving the front and rear adjustable plates 33 and the left and right adjustable base plates 28 to adapt to the production needs of cardboard boxes of different specifications.

[0074] The working process of the equipment is as follows: S1 The feeding mechanism 4 uses the suction cup 21 to pick up the cardboard and completes a short-distance pull-down action to place the cardboard on the material guide strip 20; S2 When the glue dispensing sensor 19 detects the cardboard passing by, it triggers the glue gun 17 to perform glue dispensing operation on the cardboard; S3 The feeding device 3 pushes the cardboard to the forming mechanism 2 quickly through the L-shaped push plate 22; S4 The forming mechanism 2 folds the cardboard through the forming sheet metal component 27 and further folds and presses the cardboard through the stamping component 32 to complete the final forming operation; S5 The formed cardboard box is pushed down onto the unloading conveyor belt 5 to complete the entire production process.

[0075] Through the coordinated action of various mechanisms, the equipment achieves automatic dispensing, pushing, folding, and forming of cardboard. The feeding mechanism 1, by adjusting the hopper, feeding slide rail 9, and adjusting screw 13, adapts to cardboard of different sizes to meet diverse production needs. The loading mechanism 4 achieves stable cardboard feeding through the negative pressure adsorption of the suction cup 21 and a short-stroke downward pull. The feeding device 3 controls the lifting and lowering of the L-shaped push plate 22 via the anti-interference cylinder 23 to avoid interference with the cardboard, while simultaneously improving production efficiency through rapid pushing action. The forming mechanism 2, through the coordinated operation of the forming sheet metal assembly 27 and the stamping assembly 32, ensures precise and secure folding angles of the cardboard boxes. Furthermore, the adjustment of the left and right adjusting base plates 28 and the front and rear adjusting plates 33 adapts to the production needs of cardboard boxes of different specifications.
