Detailed Embodiments
[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0019] Please refer to Figures 1-4 , the present invention provides a technical solution: a trimming device for cardboard production, including a frame 1, a positioning table 2, a conveyor belt 3, and a cardboard 4. At one end of the frame 1 close to the positioning table 2, mounting seats 5 are symmetrically and fixedly installed. At the outer inner corners of the two groups of mounting seats 5, servo motors 6 are respectively fixedly installed. At the output ends of the two groups of servo motors 6, ball screws 61 are respectively fixedly installed. A guide rod 9 passes through the middle of the two groups of mounting seats 5;
[0020] At both ends of the guide rod 9, guide sleeves 63 are respectively movably sleeved. At the tops of the two groups of guide sleeves 63, grinding mechanisms 7 and cutters 8 are respectively arranged. At the different sides of the two groups of guide sleeves 63, guide blocks 62 are respectively fixedly installed. The two groups of guide blocks 62 are respectively connected to the ball screws 61 on the same side through threaded cooperation;
[0021] A conveyor belt 3 is installed in the middle of the frame 1. Through the conveyor belt 3, the trimming support plate can be conveyed to the positioning table 2. After the conveyor belt 3 transports the cardboard 4 to be trimmed to a specified position, it stops working. The cylinder in the positioning mechanism 22 can press and position the pressing plate on the top of the cardboard 4. At this time, the side of the cardboard 4 can be trimmed by the cutter 8 in the positioning table 2. The conveyor belt 3 conveys the cardboard 4 and controls the coordinated work of the conveyor belt 3 and the cylinder in the positioning mechanism 22 through the start-stop mechanism, which is an existing technical solution in the edge cutting process of the cardboard 4 and will not be elaborated here;
[0022] After the conveyor belt 3 conveys the cardboard 4 to the specified position at the opening of the positioning table 2, the positioning mechanism 22 on the top of the positioning table 2 positions it. The two groups of servo motors 6 can be intermittently controlled to work respectively through the PLC controller, so that the cutter 8 and the grinding mechanism 7 can move intermittently and reciprocally along the guide rod 9 under the cooperation of the guide sleeves 63 on the ball screw 61 and the guide rod 9. Therefore, after trimming the cardboard 4, the trimmed position can be immediately polished, removing burrs and rough edges, so that the trimmed cardboard 4 does not need to be transferred to the deburring process for further processing.
[0023] Among them, at both ends of the frame 1, opening grooves 21 are respectively opened through. The opening grooves 21 are used to make way for the grinding mechanism 7 and the cutter 8. Guide grooves are respectively opened between the opening grooves 21 and the two groups of guide blocks 62.
[0024] Among them, a positioning mechanism 22 is further arranged on the top of the positioning table 2. The positioning mechanism 22 includes a cylinder, and a pressing plate is fixedly installed at the telescopic end of the cylinder. The pressing plate is used to position the cardboard 4 on the top of the conveyor belt 3. The trimming support plate can be conveyed to the positioning table 2 through the conveyor belt 3. After the conveyor belt 3 transports the cardboard 4 to be trimmed to the specified position, it stops working. The cylinder in the positioning mechanism 22 can press and position the pressing plate on the top of the cardboard 4.
[0025] Among them, the edge grinding mechanism 7 includes an upper grinding block 71, a lower grinding block 72 and a connecting plate 73 which are symmetrically arranged up and down. The upper grinding block 71 and the lower grinding block 72 are symmetrically and movably sleeved on the ends of the connecting plate 73. One side of the upper grinding block 71 and the lower grinding block 72 is installed with a positioning bolt 74 through a thread. The top of the connecting plate 73 is of a T-shaped structure. The L-shaped upper grinding block 71 and the lower grinding block 72 are respectively slidably sleeved on both ends of the connecting plate 73. In this way, the upper and lower grinding blocks 72 can be adjusted to approach each other and can be positioned by the positioning bolt 74, realizing synchronous grinding and deburring of the upper and lower edges after trimming cardboard 4 of different thicknesses.
[0026] Among them, the bottom end of the connecting plate 73 is fixedly installed on the same-side guide sleeve 63. The cutting knife 8 is installed on the same-side guide sleeve 63 through a support. The two servo motors 6 are electrically connected with a PLC controller. The controller controls the two servo motors 6 to work intermittently. After one of the servo motors 6 completes a cycle of forward and reverse rotation, the other servo motor 6 works again. In this way, after the cardboard 4 is trimmed, the trimming position can be immediately ground, realizing that after the cardboard 4 is trimmed, the trimming position is immediately ground to remove burrs and rough edges, so that the trimmed cardboard 4 does not need to be transferred to the deburring process for further processing.
[0027] Working principle: When in use, first place the cardboard 4 to be trimmed on the conveyor belt 3 for conveying. Then, after the conveyor belt 3 conveys the cardboard 4 to the specified position at the opening of the positioning table 2, the positioning mechanism 22 on the top of the positioning table 2 positions it;
[0028] At this time, the two servo motors 6 can be respectively controlled to work intermittently through the PLC controller. The two servo motors 6 intermittently drive the ball screw 61 to rotate. First, the cutting knife 8 can reciprocate along the guide rod 9 under the cooperation of the ball screw 61 and the guide sleeve 63 on the guide rod 9 for one cycle, trim the edge of the cardboard and then reset to the corresponding opening groove 21. Then, the edge grinding mechanism 7 can immediately grind the trimming position after trimming the cardboard 4, realizing that after the cardboard 4 is trimmed, the trimming position is immediately ground to remove burrs and rough edges, so that the trimmed cardboard 4 does not need to be transferred to the deburring process for further processing.
