Detailed Implementation
[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] This utility model provides, for example Figure 1-4 The carton cutting equipment shown includes a processing table 1, two clamping mechanisms 3 and a height adjustment mechanism 4.
[0025] A shearing table 2 is fixedly connected to the middle of the top wall of the processing table 1. A top plate 5 is provided on the top of the processing table 1. A height adjustment mechanism 4 is provided at the bottom of the top plate 5. A pressing mechanism 3 is provided on both sides of the bottom of the height adjustment mechanism 4, and the two pressing mechanisms 3 are symmetrically arranged.
[0026] Each clamping mechanism 3 includes a sliding block 31, a shrinking shell 32, a telescopic block 33, a fixing block 35, two second limit rods 36, two return springs 38, and a pressure plate 37. The sliding block 31 has sliding holes 311 at the top center near both ends. The shrinking shell 32 is fixedly connected to the bottom of the sliding block 31 on the side facing the processing table 1. One end of the telescopic block 33 is inserted into the inner cavity of the shrinking shell 32. The top of the shrinking shell 32, away from the sliding block 31, has two symmetrical fixing bolt holes, each threaded with a fixed bolt. The top of the telescopic block 33 near both ends is provided with multiple limit bolt holes at equal intervals. The fixed block 35 is fixedly connected to the side of the telescopic block 33 outside the shrink shell 32. One end of each of the two second limit rods 36 slides through the top of the fixed block 35 near both ends. The top wall of the pressure plate 37 is fixedly connected to the bottom end of the two second limit rods 36. The pressure plate 37 is located above the shearing table 2. Two return springs 38 are respectively sleeved on the two second limit rods 36, and both return springs 38 are located between the fixed block 35 and the pressure plate 37.
[0027] Before using the device, connect it to a power source. When cutting cardboard, first place it horizontally on the top wall of the shearing table 2. Then, according to the size of the cardboard, unscrew the fixing bolts 34. Next, pull the telescopic block 33 out of the shrink shell 32 to a suitable length, so that the pressure plate 37 is placed above the cardboard. After adjustment, fix the telescopic block 33 in the corresponding fixing bolt holes and limit bolt holes of the fixing bolts 34. Simultaneously start the two cylinders 49 via the controller. The cylinders 49 drive the fixing plate 41 and connecting plate 42 downwards. The fixing plate 41 drives the cutter 48 downwards, causing the cutter 48 to contact the cardboard and cut it. Start the motor 4 via the controller. 3 (Motor 43 is a bidirectional motor, which is existing technology) drives the threaded rod 44 to rotate, thereby moving the T-block 46, driving the cutter 48 to move horizontally, adjusting the cutting position of the cutter 48. When the connecting plate 42 moves downward, it drives the sliding block 31 to move downward, thereby moving the shrink shell 32, the telescopic block 33 and the fixing block 35 downward. When the pressure plate 37 contacts the cardboard with the rubber pad 39, it presses the cardboard to prevent the cardboard from shifting. During the process of the pressure plate 37 pressing the cardboard, the pressure plate 37 moves upward. The second limit rod 36 limits the movement of the pressure plate 37. At this time, the return spring 38 is squeezed and contracts to achieve a buffering effect, preventing the pressure plate 37 from excessively squeezing the cardboard and causing damage to the cardboard.
[0028] Two fixing bolt holes correspond to a row of limit bolt holes respectively. The fixing bolt 34 is threadedly connected to the limit bolt holes. Limit plates are fixedly connected to the top of the two second limit rods 36.
[0029] The fixing bolt 34 is screwed into the corresponding fixing bolt hole and the limiting bolt hole to facilitate the limiting of the telescopic block 33. The limiting plate limits the second limiting rod 36 to prevent the second limiting rod 36 from moving out of the fixing block 35.
[0030] Two first limiting rods 8 are symmetrically provided at the middle position on both sides of the top wall of the processing table 1. One end of each first limiting rod 8 is fixedly connected to the top wall of the processing table 1 and the other end is fixedly connected to the bottom wall of the top plate 5. The two sliding holes 311 on the two sliding blocks 31 are respectively slidably sleeved on the two first limiting rods 8 on the same side.
[0031] The first limiting rod 8 limits the movement of the sliding block 31 and the connecting plate 42, so that the sliding block 31 and the connecting plate 42 move along the first limiting rod 8.
[0032] Both cylinders 49 and motor 43 are electrically connected to an external controller.
[0033] The controller has a built-in control program, which allows the operator to control the cylinder 49 and the motor 43, making it easy to cut the carton.
[0034] The height adjustment mechanism 4 includes two cylinders 49, a fixed plate 41, two connecting plates 42, a motor 43, two limiting plates 45, a threaded rod 44, and a T-block 46. The fixed ends of the two cylinders 49 are symmetrically fixedly connected to the middle of the bottom wall of the top plate 5 near both sides. The telescopic ends of the two cylinders 49 are fixedly connected to the top wall of the fixed plate 41. The two connecting plates 42 are respectively fixedly connected to both sides of the fixed plate 41. The top of the two connecting plates 42 near both ends is provided with through holes. The two through holes on the connecting plate 42 on the same side are respectively slidably fitted onto the two first limiting rods 8 on the same side. The connecting plate 42 on the same side is fixedly connected to the top wall of the sliding block 31 on the same side. The two limiting plates 45 are respectively fixedly connected to the bottom wall of the fixed plate 41 near both ends. The middle of the side wall of the two limiting plates 45 is provided with... The device has an installation port, and each installation port has an embedded bearing 451. A limiting groove 411 is opened on the bottom wall of the fixing plate 41 between the two limiting plates 45. The threaded rod 44 is fixedly connected to the inner ring of the two bearings 451 near both ends. The motor 43 is fixedly connected to the bottom wall of the fixing plate 41 near the right side. The right end of the threaded rod 44 passes through the right limiting plate 45 and is fixedly connected to the output end of the motor 43. The protruding wall of the T-block 46 is slidably connected to the limiting groove 411. A threaded hole 461 is opened in the middle of the connecting wall of the T-block 46. The threaded hole 461 is threadedly connected to the threaded rod 44. The two cylinders 49 and the motor 43 are electrically connected to an external controller. A movable plate 47 is fixedly connected to the bottom wall of the connecting wall of the T-block 46. A cutter 48 is fixedly connected to the bottom wall of the movable plate 47. The cutter 48 is 3-5cm higher than the pressure plate 37.
[0035] Two cylinders 49 are activated synchronously by the controller. Cylinders 49 drive the fixed plate 41 and connecting plate 42 to move downward. The fixed plate 41 drives the cutter 48 to move downward, so that the cutter 48 contacts the cardboard and cuts the cardboard. When the cutting position of the cutter 48 is required, the controller starts the motor 43. The motor 43 drives the threaded rod 44 to rotate. Under the limit of the limiting groove 411 and the action of the threaded hole 461, when the threaded rod 44 rotates, the T-block 46 moves along the threaded rod 44, thereby driving the cutter 48 at the bottom of the moving plate 47 to move and adjust the cutting position. The limiting plate 45 supports the threaded rod 44, and the bearing 451 facilitates the rotation of the threaded rod 44. The cutter 48 is higher than the pressure plate 37. The pressure plate 37 first presses the cardboard tightly, and the return spring 38 contracts (the contraction range of the spring 38 meets the cutting of the cutter 48). The cutter 48 continues to move downward to cut the cardboard.
[0036] A support column 6 is provided at the top of the processing table 1 near the four corners. The bottom end of each support column 6 passes through the processing table 1 and extends to the bottom of the processing table 1. A support base 7 is fixedly connected to the bottom end of the support column 6. The top ends of the four support columns 6 are fixedly connected to the bottom wall of the top plate 5 near the four corners.
[0037] The support column 6 supports and fixes the top plate 5, and the support base 7 is used to increase the grounding area and improve the stability of the device.
