Description

Technical Field

[0001] The utility model relates to the technical field of box body manufacturing, and in particular discloses an automatic corner pasting machine. Background Art

[0002] In the modern packaging industry, paper boxes are a common form of packaging, widely used in the packaging and transportation of various commodities. The production quality and efficiency of paper boxes directly affect the protection effect and market competitiveness of commodities.

[0003] Traditional carton production typically involves bending and forming the carton before taping. This process involves bending grayboard material to form the basic shape of the carton, then applying tape at key locations to secure and strengthen the carton structure. This method has significant drawbacks, including complex production processes and low efficiency. Especially in high-volume production, process complexity and low production efficiency become significant productivity constraints. Utility Model Content

[0004] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present invention is to provide a corner pasting machine with high production efficiency, high automation, good tape pasting effect and high structural stability of the finished product.

[0005] To achieve the above-mentioned purpose, the present invention provides an automatic corner pasting machine, comprising a frame and a conveying mechanism, a gluing mechanism, and a corner pasting mechanism arranged on the frame. The conveying mechanism is connected to the gluing mechanism and the corner pasting mechanism in sequence. The conveying mechanism is used to transport external gray boards, the gluing mechanism is used to apply tape to the gray boards, and the corner pasting mechanism is used to bend the gray boards with tape applied and perform corner pasting to form them into box bodies. In the present invention, the gray boards are transported by the conveying mechanism, are applied with tape by the gluing mechanism, and are then bent and corner pasted by the corner pasting mechanism to finally form the box body, thus realizing automatic gluing and forming of the gray boards. This solves the problem of complicated and time-consuming operations of first bending and forming and then applying tape in traditional box body manufacturing, thus simplifying the operation process and improving production efficiency.

[0006] Furthermore, the adhesive laminating mechanism includes a base plate, a clamping assembly mounted on the base plate, a tape placement assembly mounted on the clamping assembly, and a tape cutting assembly. The base plate is rotatably connected to the frame, and the tape placement assembly is wound around an external tape. The clamping assembly includes a clamping base, one end of which is connected to the base plate, and a guide wheel mounted on the other end of the base plate. The guide wheel contacts the tape and adheres it to the gray board. The tape cutting assembly is used to cut the tape. The tape placement assembly provides the tape, the clamping assembly adheres the tape to the gray board via the guide wheel, and the tape cutting assembly drives a cutter to cut the tape via a cutting cylinder. This ensures that the tape is accurately and securely adhered to the gray board and can be precisely cut, thereby improving the efficiency and quality of adhesive laminating.

[0007] Furthermore, the rubber cutting assembly includes a cutter, a cutter holder, and a rubber cutting cylinder for the briquetting machine. The cutter cylinder is mounted on a pressing base, and the cutter holder is connected to the cutter cylinder. One end of the cutter holder is rotatably connected to the pressing base, and the other end of the cutter holder is connected to the cutter. The cutter cylinder drives the cutter holder to rotate relative to the pressing base, and the rotating cutter holder drives the cutter to cut the tape. The cutter cylinder drives the cutter holder and cutter to rotate, ultimately achieving tape cutting. The operation of cutting the tape is simple and precise, ensuring the continuity and stability of the adhesive application process, improving the degree of automation, and enhancing production efficiency.

[0008] Furthermore, the gluing mechanism also includes a limit assembly, which includes a support rod connected to the frame, two sets of first limit plates respectively provided at both ends of the support rod, and a second limit plate provided on the support rod. The two sets of first limit plates are connected to the frame via a screw rod. A gap is left between the end of the second limit plate closest to the conveying mechanism and the conveying mechanism, and the gap is used for the passage of an external gray board. The first limit plate controls the movement path and position of the gray board, ensuring the gray board's accurate position during the gluing process and improving the gluing effect. The second limit plate controls the passage of a single gray board to prevent the gray boards from sticking.

[0009] Furthermore, the glue applying mechanism is provided with two groups, which are movably mounted on the base plate. The two groups of glue applying mechanisms can work separately or simultaneously, thereby improving glue applying efficiency.

[0010] Furthermore, the corner-fixing mechanism includes a pushing assembly and a corner-fixing assembly. The pushing assembly includes a pushing base slidably mounted on a frame, a pushing motor mounted on the pushing base, and a pushing member connected to the pushing motor. The pushing motor drives the pushing member to push the gray board, and the pushing member cooperates with the corner-fixing assembly to bend the gray board and fix the corners to form the box body. This achieves automatic bending and forming of the gray board, improving production efficiency and product quality.

[0011] Furthermore, the push member includes a support base plate connected to a push motor and push rods mounted on the support base plate. The push rods are elongated rods and are provided in multiple groups arranged in a rectangular array along the support base plate. The multiple groups of push rods provide a stable push force, and the rectangular array of multiple push rods evenly distributes force on the mortar board, improving the bending effect and the molding quality of the box body.

[0012] Furthermore, the corner bend assembly includes a corner bend base and a guide rod mounted on the corner bend base. The guide rod has a guide arc surface at one end near the plasterboard. The plasterboard is bent along the guide arc surface of the guide rod, ensuring a smooth bending process, improving bending accuracy and quality, and reducing damage to the plasterboard.

[0013] Furthermore, the corner-attaching assembly includes a drive motor mounted on the corner-attaching base, which drives a scraper connected to the drive motor. The drive motor drives the scraper to contact the adhesive tape on the grayboard, causing the tape to adhere to the grayboard. The drive motor drives the scraper to move, ensuring a tight fit between the tape and the grayboard, improving the firmness and accuracy of the adhesive tape and grayboard adhesion, and ensuring the structural stability of the formed box body.

[0014] Furthermore, the corner pasting components are provided in four groups, and the four groups of corner pasting components are arranged in a rectangular array along the frame. The four groups of corner pasting components can work simultaneously or separately, thereby improving the corner pasting efficiency.

[0015] The beneficial effects of the present invention are as follows: in the present invention, the gray board is conveyed by a conveying mechanism, pasted with tape by a gluing mechanism, and then bent and angled by an angle-pasting mechanism to finally form a box body, thereby realizing automatic gluing and forming of the gray board, solving the problem that the traditional box body manufacturing requires complicated operations such as bending and forming first and then taping, which takes a lot of time, simplifying the operating procedures and improving production efficiency; the moving path and position of the gray board are controlled by the first limiting plate to ensure that the gray board is accurately positioned during the gluing process, thereby improving the gluing effect; the single gray board is controlled to pass through by the second limiting plate to avoid adhesion of the gray board.

[0027] See also Figures 1 to 8 As shown, the utility model is an automatic corner pasting machine, including a frame 1 and a conveying mechanism 2, a gluing mechanism 3 and a corner pasting mechanism 4 arranged on the frame 1. The conveying mechanism 2 is connected to the gluing mechanism 3 and the corner pasting mechanism 4 in sequence. The conveying mechanism 2 is used to transport external gray boards, the gluing mechanism 3 is used to apply tape to the gray boards, and the corner pasting mechanism 4 is used to bend the gray boards with tape applied and paste the corners to form them into box bodies. In the utility model, the gray boards are transported by the conveying mechanism 2, pasted with tape by the gluing mechanism 3, and then bent and pasted by the corner pasting mechanism 4 to finally form the box body, realizing automatic gluing and forming of the gray boards, solving the problem of complicated and time-consuming operations of first bending and forming and then applying tape in traditional box body manufacturing, simplifying the operation process and improving production efficiency.

[0028] Specifically, the conveying mechanism 2 is a conveyor belt.

[0029] The adhesive laminating mechanism 3 includes a base plate 31, a clamping assembly 32 disposed on the base plate 31, a tape placement assembly 33 disposed on the clamping assembly 32, and a tape cutting assembly 34. The base plate 31 is rotatably connected to the frame 1, and an external tape is wound around the tape placement assembly 33. The clamping assembly 32 includes a clamping base 321, one end of which is connected to the base plate 31, and a guide wheel 322 is disposed at the other end of the clamping base 321. The guide wheel 322 contacts the tape and adheres it to the gray board. The tape cutting assembly 34 is used to cut the tape. The tape placement assembly 33 provides the tape, the clamping assembly 32 adheres the tape to the gray board via the guide wheel 322, and the tape cutting assembly 34 drives the cutter 341 via the tape cutting cylinder 343 to cut the tape. This ensures that the tape is accurately and firmly adhered to the gray board and can be precisely cut, thereby improving the efficiency and quality of adhesive laminating.

[0030] The rubber cutting assembly 34 includes a cutter 341, a cutter holder 342, and a rubber cutting cylinder 343 for the briquetting machine. The rubber cutting cylinder 343 is mounted on the pressing base 321. The cutter holder 342 is connected to the rubber cutting cylinder 343 in a driving manner. One end of the cutter holder 342 is rotatably connected to the pressing base 321, and the other end of the cutter holder 342 is connected to the cutter 341. The rubber cutting cylinder 343 drives the cutter holder 342 to rotate relative to the pressing base 321. The rotating cutter holder 342 drives the cutter 341 to cut the tape. The rubber cutting cylinder 343 drives the cutter holder 342 and the cutter 341 to rotate, ultimately cutting the tape. The operation of cutting the tape is simple and precise, ensuring the continuity and stability of the adhesive application process, improving the degree of automation, and enhancing production efficiency.

[0031] The gluing mechanism 3 also includes a limiting assembly 35, which comprises a support rod 351 connected to the frame 1, two sets of first limiting plates 352 respectively disposed at each end of the support rod 351, and a second limiting plate 353 disposed on the support rod 351.

The pushing assembly 41 includes a pushing base 411 slidably mounted on the frame 1, a pushing motor 412 mounted on the pushing base 411, and a pushing member 413 connected to the pushing motor 412. The pushing motor 412 drives the pushing member 413 to push the grayboard. The pushing member 413 cooperates with the corner-fixing assembly 42 to bend the grayboard and fix the corners to form a box body. This achieves automatic bending and forming of the grayboard, improving production efficiency and product quality.

[0034] The push member 413 includes a support base 4131 drivingly connected to the push motor 412, and push rods 4132 disposed on the support base 4131. The push rods 4132 are elongated rods and are provided in multiple groups arranged in a rectangular array along the support base 4131. The multiple groups of push rods 4132 provide a stable push force, and the rectangular array of the multiple groups of push rods 4132 evenly distributes the force on the gray board, improving the bending effect and the molding quality of the box body.

[0036] Specifically, the corner base 421 is slidably mounted on the frame 1. The slidable corner base 421 on the frame 1 facilitates adjustment of the position of the corner assembly 42 to accommodate the production needs of cartons of different sizes and shapes. The position and number of the corner assembly 42 can be adjusted according to different carton designs to achieve diversified production.

[0037] Corner-attaching assembly 42 also includes a drive motor 423 mounted on corner-attaching base 421 and a drive blade 424 connected to drive motor 423. Drive motor 423 drives blade 424 to contact the adhesive tape on the grayboard, causing the tape to adhere to the grayboard. Drive motor 423 drives blade 424 to ensure a tight fit between the adhesive tape and the grayboard, improving the firmness and accuracy of the adhesive tape and grayboard adhesion, and ensuring the structural stability of the formed box body.

[0040] Specifically, the output component 52 is a conveyor belt.

[0041] In this embodiment, the gray board is transported to the position of the gluing mechanism 3 by the conveying mechanism 2. The limiting component 35 ensures that the gray board maintains the correct position during the conveying process and ensures that the gray board is accurately positioned.

After the gray board reaches the gluing mechanism 3, the pressing component 32 fixes the gray board in an appropriate position, the tape placing component 33 pulls out the tape, and the guide wheel 322 sticks the tape to the designated position of the gray board. After the tape is pasted, the cutting glue component 34 is started. Cut the tape; the gray board with the tape is transported to the corner pasting mechanism 4 through the conveying mechanism 2, the pushing assembly 41 is started, and the pushing motor 412 drives the pushing part 413 to push the gray board toward the corner pasting assembly 42, the guide rod 422 bends the corners of the gray board, and the guiding arc surface 4221 helps the gray board to bend and shape smoothly, and the driving motor 423 drives the scraper 424 to make the scraper 424 stick to and press the tape on the gray board to ensure that the tape and the gray board are firmly bonded.
