Description

Technical Field

[0001] This utility model belongs to the field of case opener technology, and in particular relates to a case opener with a high-performance transmission mechanism. Background Technology

[0002] The related technology discloses a carton opening machine with announcement number CN222081016U. This device can effectively transport cartons downward by setting a conveyor slide. Its limiting block and limiting baffle work together to effectively prevent cartons from tipping over. Its rotating motor can effectively drive the rotating rod to rotate, thereby driving the conveyor belt through the pulley. After the cartons slide onto the conveyor belt, they can be transported. The limiting belt can effectively limit the cartons transported on the conveyor belt.

[0003] However, when clamping the blanks, the device squeezes and clamps them to one side of the blank placement rack. This method is not conducive to ensuring that the blanks are in the precise preset position each time, which may affect the accuracy of subsequent opening actions, resulting in unsmooth opening, uneven box openings, and other problems, which seriously restricts production efficiency and product quality. Utility Model Content

[0004] The purpose of this invention is to provide a box opener with a high-performance transmission mechanism. By setting up a clamping mechanism, it solves the problem of squeezing and clamping the box blank to one side of the box blank placement rack. This method is not conducive to ensuring that the box blank is in a precise preset position every time, which may affect the accuracy of subsequent box opening actions, resulting in unsmooth box opening, uneven box openings, and other problems, which seriously restrict production efficiency and product quality.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a box opener with a high-performance transmission mechanism, comprising a chassis, on which a clamping mechanism and a box-removing mechanism are provided.

[0007] The clamping mechanism includes a blank placement rack fixedly connected to the front side of the chassis. A bidirectional threaded rod is rotatably connected to the inner wall of the blank placement rack. The right end of the bidirectional threaded rod extends to the outside of the blank placement rack. A handle is fixedly connected to the right end of the bidirectional threaded rod. Two internal threaded blocks are threadedly connected to the bidirectional threaded rod. A clamping block is fixedly connected to the top of each of the two internal threaded blocks. Two sliding rods are fixedly connected to the inner wall of the blank placement rack. A slider is slidably connected to each of the two sliding rods. Each of the two sliders is fixedly connected to a corresponding clamping block.

[0008] Furthermore, a central beam block is fixedly connected to the inner wall of the box blank placement rack, and a T-shaped sliding groove is provided on the top of the central beam block.

[0009] Furthermore, a slide plate is slidably connected to the inner wall of the T-shaped groove, the top of the slide plate extends to the outside of the central beam block, and an extrusion plate is fixedly connected to the rear side of the slide plate.

[0010] Furthermore, the box-retrieving mechanism includes a motor fixedly connected to the top of the chassis, the output shaft of the motor being fixedly connected to a rotating shaft via a coupling, and a gear being fixedly connected to the rotating shaft.

[0011] Furthermore, a second rotating shaft is rotatably connected to the inner top wall of the chassis, and a second gear is fixedly connected to the bottom end of the second rotating shaft, which meshes with the first gear.

[0012] Furthermore, a turntable is fixedly connected to the bottom end of the second rotating shaft, a fixed rod is fixedly connected to the bottom of the turntable, and a hinge plate is rotatably connected to the bottom end of the fixed rod.

[0013] Furthermore, two guide rods are fixedly connected to the inner wall of the chassis, and two sliders are slidably connected to each of the two guide rods. A connecting plate is fixedly connected between the two sliders, and the hinge plate is hinged to the connecting plate on the side away from the fixed rod.

[0014] Furthermore, a box-retrieving plate is fixedly connected to the bottom of the two sliders, and several suction cups are fixedly connected to the front side of the box-retrieving plate. A control box is fixedly connected to the front side of the chassis, and a conveyor table is fixedly connected to the left side of the chassis.

[0015] This utility model has the following beneficial effects:

[0016] 1. By setting up a clamping mechanism, rotating the handle drives the bidirectional threaded rod to rotate, which in turn moves the internal threaded block, which in turn moves the clamping block, which in turn moves the slider on the slide rod. The clamping mechanism clamps the blanks on the blank placement rack, thus accommodating blanks of different sizes and firmly fixing them regardless of their size. At the same time, it ensures that the blank is always in the exact center of the blank placement rack, making subsequent mechanical operations more precise and efficient. This avoids gripping failures or opening errors due to blank position deviation. Moreover, stable positioning ensures that all links are closely connected during the entire opening operation, greatly improving opening efficiency and ensuring that the opening work is continuous and smooth.

[0017] 2. By setting up a box-retrieving mechanism, the motor is started, driving the first rotating shaft to rotate. The rotation of the first rotating shaft drives the first gear to rotate, which in turn drives the second gear to rotate. The second gear then drives the second rotating shaft to rotate, which in turn drives the turntable to rotate. The turntable's rotation drives the fixed rod to rotate, which in turn moves the hinge plate. The hinge plate's movement drives the connecting plate to move, which in turn moves the second slider to slide on the guide rod. The movement of the second slider then moves the box-retrieving plate and the suction cup. Through the box-retrieving mechanism, the first gear, with its larger size and torque, drives the second gear to rotate at high speed. Due to the difference in diameter, the second gear rotates several times faster than the first gear, giving subsequent mechanical actions a faster pace and greatly improving the overall working efficiency of the box-retrieving machine. This allows the box-retrieving and opening process to operate at lightning speed. Simultaneously, the coordinated work between the various components converts rotational motion into linear motion, ensuring not only smooth and stable movement but also precise execution of each box-retrieving and opening action, greatly reducing operational errors and laying a solid foundation for efficient and stable box-retrieving operations.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6As shown, this utility model is a box opener with a high-performance transmission mechanism, including a housing 1. The housing 1 is equipped with a clamping mechanism 2 and a box retrieval mechanism 3. The clamping mechanism 2 includes a box blank placement rack 21 fixedly connected to the front side of the housing 1. A bidirectional threaded rod 22 is rotatably connected to the inner wall of the box blank placement rack 21. The right end of the bidirectional threaded rod 22 extends to the outside of the box blank placement rack 21, and a handle 23 is fixedly connected to the right end of the bidirectional threaded rod 22. Two internal threaded blocks 24 are threadedly connected to the bidirectional threaded rod 22, and clamping blocks 25 are fixedly connected to the top of each of the two internal threaded blocks 24. Two sliding rods 26 are fixedly connected to the inner wall of the box blank placement rack 21, and sliders 27 are slidably connected to each of the two sliding rods 26. Each slider 27 is fixedly connected to a corresponding clamping block 25. The inner wall of the box blank placement rack 21... A central beam block 28 is fixedly connected to the wall. A T-shaped groove 29 is provided on the top of the central beam block 28. A sliding plate 210 is slidably connected to the inner wall of the T-shaped groove 29. The top of the sliding plate 210 extends to the outside of the central beam block 28. An extrusion plate 211 is fixedly connected to the rear side of the sliding plate 210. The box blanks on the box blank placement rack 21 are clamped by the clamping mechanism 2, so as to adapt to box blanks of different sizes. Regardless of size, they can be firmly fixed. At the same time, it can ensure that the box blank is always in the center of the box blank placement rack 21, so that the subsequent mechanical operation is more precise and efficient, avoiding the failure of gripping or opening error due to the position of the box blank. Moreover, the stable positioning can ensure that all links are closely connected in the entire opening operation, greatly improving the opening efficiency and ensuring that the opening work is continuous and smooth.The box-retrieving mechanism 3 includes a motor 31 fixedly connected to the top of the housing 1. The output shaft of the motor 31 is fixedly connected to a rotating shaft 32 via a coupling. A gear 33 is fixedly connected to the rotating shaft 32. A rotating shaft 34 is rotatably connected to the inner top wall of the housing 1. A gear 35 is fixedly connected to the bottom end of the rotating shaft 34, and the gear 35 meshes with the gear 33. A turntable 36 is fixedly connected to the bottom end of the rotating shaft 34. A fixing rod 37 is fixedly connected to the bottom of the turntable 36. A hinge plate 38 is rotatably connected to the bottom end of the fixing rod 37. Two guide rods 39 are fixedly connected to the inner wall of the housing 1. A slider 310 is slidably connected to each of the two guide rods 39. A connecting plate 311 is fixedly connected between the two sliders 310. The side of the hinge plate 38 away from the fixing rod 37 is hinged to the connecting plate 311. A box-retrieving plate 312 is fixedly connected to the bottom of the machine. Several suction cups 313 are fixedly connected to the front of the box-retrieving plate 312. A control box 314 is fixedly connected to the front of the machine housing 1. A conveyor table 315 is fixedly connected to the left side of the machine housing 1. Through the box-retrieving mechanism 3, gear one 33, with its larger size and torque, drives gear two 35 to rotate at high speed. Due to the difference in diameter between the two, the rotational speed of gear two 35 is several times that of gear one 33, giving subsequent mechanical actions a faster rhythm and greatly improving the overall working efficiency of the box-retrieving and box-opening machine. This allows the box-retrieving and box-opening process to run at high speed. At the same time, through the coordinated work between various components, the rotational motion is converted into linear motion, which not only ensures the smoothness of the movement, but also ensures that each box-retrieving and box-opening action is accurate and precise, greatly reducing operational errors and laying a solid foundation for efficient and stable box-opening operations.

[0030] A specific application of this embodiment is as follows: When using the device, first place the unopened blank ingot on top of the blank ingot placement rack 21, then rotate the handle 23. When the handle 23 rotates, it drives the bidirectional threaded rod 22 to rotate. When the bidirectional threaded rod 22 rotates, it drives the internal threaded block 24 to move. When the internal threaded block 24 moves, it drives the clamping block 25 to move. When the clamping block 25 moves, it drives the slider 27 to slide on the slide rod 26. Through the slide rod 26 and the slider 27, the clamping block 25 is made more stable during the movement. At the same time, the slide rod 26 and the slider 27 limit the internal threaded block 24, converting the rotational motion of the internal threaded block 24 into a linear motion. The clamping block 25 can clamp boxes of any size placed on the box blank placement rack 21 within a certain range, while keeping the box blanks in the center of the box blank placement rack 21. As the number of box blanks on the box blank placement rack 21 decreases, the extrusion plate 211 moves under its own gravity, thereby driving the slide plate 210 to slide in the T-shaped slide groove 29. The extrusion plate 211 then pushes the remaining box blanks forward, ensuring that the box blanks can be continuously supplied to the gripping range of the suction cup 313. This allows the box opening machine to pick up boxes continuously without interruption due to the box blanks being placed too far back, maintaining the smoothness of the box opening operation.

[0031] After the boxes on the box placement rack 21 are placed, the box unloading machine begins operation. First, the motor 31 is started, which drives the rotating shaft 32 to rotate. When the rotating shaft 32 rotates, it drives the gear 33 to rotate. When the gear 33 rotates, it drives the gear 35 to rotate. When the gear 35 rotates, it drives the rotating shaft 34 to rotate. When the rotating shaft 34 rotates, it drives the turntable 36 to rotate. Since the diameter of the gear 33 is larger than that of the gear 35, when the gear 33 rotates one revolution, the gear 35 will rotate more than one revolution. When the turntable 36 rotates, it drives the fixed rod 37 to rotate. When the fixed rod 37 rotates, it drives the hinge plate 38 to move. When the machine moves, it drives the connecting plate 311 to move. When the connecting plate 311 moves, it drives the second slider 310 to slide on the guide rod 39. The guide rod 39 and the second slider 310 limit and guide the movement path of the connecting plate 311, thereby converting the rotational motion of the turntable 36 to the connecting plate 311 into linear motion. When the connecting plate 311 drives the second slider 310 to move, the second slider 310 drives the box-retrieving plate 312 to move, thereby causing the box-retrieving plate 312 to move back and forth. Thus, through the cooperation of the suction cup 313 and the box-retrieving plate 312, the box-retrieving and opening task of the box blank is repeatedly completed. Finally, the opened box is transported out of the machine box 1 through the conveyor table 315.
