Description

Technical Field

[0001] This utility model belongs to the field of cardboard box processing technology, and specifically relates to a cardboard box cutting device. Background Technology

[0002] Cardboard box cutting equipment refers to specialized equipment used for precise cutting and creasing of cardboard materials. It achieves efficient cutting through high-frequency vibration of the blade (tens of thousands of times per minute), similar to "sawing" but without producing debris. It does not require the creation of die-cutting molds and can be cut directly by importing electronic drawings. It is a commonly used cutting and processing equipment for corrugated paper, grey board, cardboard, honeycomb board, and other cardboard boxes. According to the platform type, it can be divided into non-conveyor belt fixed platforms and conveyor belt integrated platforms. Among them, the conveyor belt integrated platform supports continuous feeding of cardboard and is suitable for mass production.

[0003] Existing cardboard box cutting equipment has poor demolding ability. Although the cardboard has been cut and cut marks have been made, the cardboard will still be connected to the unfolding template due to friction caused by cutting defects (burrs, fiber direction, etc.). The unfolding template needs to be manually removed to separate the two so that the cardboard can be folded and formed later. In the mass production of cardboard, this demolding method is too inefficient, time-consuming and occupies human resources for a long time. Utility Model Content

[0004] The purpose of this invention is to provide a carton cutting device that uses a narrow conveyor belt and rollers to clamp and transport the carton template output by the cutting device. During the movement of the carton template, an adjusting plate pushes the die template of the carton downward, which can separate the die template from the waste cardboard and make the die template automatically stacked at the bottom of the receiving rack. This can improve demolding efficiency, eliminate the need for manual demolding and material separation, and save manpower and time.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A cardboard box cutting device includes a cutting device and a receiving rack fixedly assembled at its output end. The receiving rack is used to receive cardboard and is U-shaped with its opening facing upwards. Narrow conveyor belts are driven and assembled on the inner walls of both sides of the top of the receiving rack. Several fixed rods are linearly arranged on both sides of the top of the receiving rack. A roller is rotatably connected to one end of each fixed rod and above the narrow conveyor belt. Lifting and adjusting mechanisms for controlling the vertical movement of the fixed rods are provided on both sides of the top of the receiving rack. A bridge is fixedly connected to the top of the receiving rack. Sliding columns are symmetrically slidably connected to the bottom of the bridge. A support plate is fixedly connected to the outer wall of each sliding column. An adjusting plate is rotatably connected to the bottom of each sliding column. A spring column is elastically connected to one end of the support plate. One end of the spring column is fixedly connected to one end of the adjusting plate. A roller is rotatably connected to the bottom of one end of the adjusting plate.

[0007] The lifting and adjusting mechanism includes a fixed plate that is fixedly installed on the outer walls of both sides of the receiving rack, and a screw that can be manually rotated is rotatably connected to the middle of the fixed plate.

[0008] A lifting plate is fixedly connected to one end of several fixed rods located on the same side. A screw is threadedly connected to the lifting plate. Rotation of the screw can control the lifting plate and roller to lift and lower, adapting to different thicknesses of cardboard. The top of both sides of the receiving rack is provided with slots for the fixed rods to move and fit together.

[0009] Limiting rods are fixedly connected to both ends of the lifting plate, and the lifting plate is slidably connected to the fixed plate through the limiting rods to restrict the vertical movement of the lifting plate.

[0010] The top of the sliding column is fixedly connected to a screw rod two. A sliding groove for the screw rod two to slide through is opened in the middle of the cable frame. A fastening nut is threadedly connected to one end of the screw rod two and located above the cable frame. By tightening the fastening nut, the friction with the cable frame can be increased, which is used to adjust and fix the position of the sliding column.

[0011] The technical effect achieved by this utility model is as follows: the cardboard template output by the narrow-faced conveyor belt and roller clamping and conveying the cardboard template is separated from the waste cardboard by the downward pushing of the cardboard die template by the adjusting plate during the movement of the cardboard template. The die template is automatically stacked at the bottom of the receiving rack, which can improve the demolding efficiency, eliminate the need for manual demolding and material separation, and save manpower and time.

Detailed Implementation

[0018] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0019] like Figures 1-3 As shown, a cardboard box cutting device includes a cutting device 1 and a receiving rack 2 fixedly assembled at its output end. The receiving rack 2 is used to receive cardboard and is U-shaped with the opening facing upwards. Narrow conveyor belts 201 are driven and assembled on the inner walls of both sides of the top of the receiving rack 2. Several fixed rods 205 are linearly arranged on both sides of the top of the receiving rack 2. One end of the fixed rod 205 and above the narrow conveyor belt 201 is rotatably connected to a roller 206. Lifting and adjusting mechanisms for controlling the vertical movement of the fixed rods 205 are provided on both sides of the top of the receiving rack 2. The lifting and adjusting mechanisms include fixed plates 202 fixedly installed on the outer walls of both sides of the receiving rack 2. The middle of the fixed plate 202 is rotatably connected to a screw 203 that can be operated by manual rotation. One end of several fixed rods 205 located on the same side is fixedly connected to a lifting plate 204. The screw 203 is threadedly connected to the lifting plate 204. Rotation of the screw 203 can control the lifting plate 204 and the roller 206 to lift and lower, adapting to different thicknesses of cardboard. Limiting rods 208 are fixedly connected to both ends of the lifting plate 204. The lifting plate 204 is slidably connected to the fixed plate 202 through the limiting rods 208 to limit the vertical movement of the lifting plate 204. The top of both sides of the receiving rack 2 are provided with slots 207 for the fixed rods 205 to be movably fitted.

[0020] According to the above structure, after the cutting equipment 1 cuts the cardboard, the conveyor belt of the cutting equipment 1 drives the cardboard box receiving rack 2 to move. The narrow conveyor belt 201 starts to run through the power and motor. When one end of the cardboard is transported to the narrow conveyor belt 201 by the cutting equipment 1, the cardboard is located between the narrow conveyor belt 201 and the roller 206. The narrow conveyor belt 201 and the roller 206 are responsible for clamping and restricting the two ends of the cardboard to prevent them from tilting up. At the same time, the narrow conveyor belt 201 drives the cardboard to continue to move. By rotating the screw 203 and under the rotation restriction of the lifting plate 204 by the limit rod 208, the lifting plate 204 can be vertically lifted and lowered. The lifting plate 204 can drive the fixed rod 205 and the roller 206 to be lifted and lowered together to adapt to cardboard of different thicknesses. The groove 207 can be used for the fixed rod 205 to be engaged during the lifting and lowering process to prevent the top of the receiving rack 2 from obstructing the fixed rod 205.

[0021] See attached document Figures 1-2 , Figure 4 The top of the receiving rack 2 is fixedly connected to a bridge frame 209. The bottom of the bridge frame 209 is symmetrically slidably connected to a sliding column 210. The top of the sliding column 210 is fixedly connected to a screw rod 211. The middle of the bridge frame 209 is provided with a through-hole for the screw rod 211 to slide. One end of the screw rod 211, located above the bridge frame 209, is threadedly connected to a fastening nut 213. Tightening the fastening nut 213 can increase the friction with the bridge frame 209 and is used to adjust the position of the fixed sliding column 210. The outer wall of the sliding column 210 is fixedly connected to a support plate 216. The bottom of the sliding column 210 is rotatably connected to an adjusting plate 214. One end of the support plate 216 is elastically connected to a spring column 215. One end of the spring column 215 is fixedly connected to one end of the adjusting plate 214. The bottom of one end of the adjusting plate 214 is rotatably connected to a roller 217.

[0022] According to the above structure, when the narrow conveyor belt 201 moves the cardboard, one end of the cardboard first contacts the roller 217 at the bottom of the adjusting plate 214. The adjusting plate 214 is squeezed by the cardboard and rotates slightly upward. The spring column 215 begins to contract and store elastic potential energy. The cardboard continues to move until the die template that has been cut in the middle contacts the roller 217. When the weak edge area (such as rough edges or micro-adhesion) of the die template is squeezed by the adjusting plate 214, the stress concentration point is broken, realizing the separation of the die template and the cardboard. The die template falls and is piled at the bottom of the receiving rack 2, while the cardboard continues to move under the drive of the narrow conveyor belt 201 and falls on one side of the receiving rack 2. The sliding column 210 slides along the bottom of the bridge frame 209. The adjustable plate 214 can be moved to adjust its position to accommodate cardboard with different die shapes (such as square, rectangular, trapezoidal, etc.). Rotating the fastening nut 213 causes it to descend through its connection with the screw 211. The fastening nut 213 is in contact with the bridge frame 209, and the friction between the two can fix the position of the sliding column 210. This utility model uses a narrow conveyor belt 201 and roller 206 to clamp and convey the cardboard template output by the cutting equipment 1. During the movement of the cardboard template, the adjusting plate 214 pushes the die template of the cardboard downward, which can separate the die template from the waste cardboard and make the die template automatically stacked at the bottom of the receiving rack 2. This can improve demolding efficiency, eliminate the need for manual demolding and material separation, and save manpower and time.

[0023] The working principle of this utility model is as follows: After the cutting equipment 1 cuts the cardboard, the conveyor belt of the cutting equipment 1 drives the cardboard box receiving rack 2 to move. The narrow conveyor belt 201 starts to run through electricity and motor. When one end of the cardboard is conveyed by the cutting equipment 1 onto the narrow conveyor belt 201, the cardboard is located between the narrow conveyor belt 201 and the roller 206. The narrow conveyor belt 201 and the roller 206 are responsible for clamping and restricting both ends of the cardboard to prevent them from tilting up. At the same time, the narrow conveyor belt 201 drives the cardboard to continue moving. By rotating the screw 203 and under the rotation restriction of the lifting plate 204 by the limit rod 208, the lifting plate 204 can be vertically lifted and lowered. The lifting plate 204 can drive the fixed rod 205 and the roller 206 to be lifted and lowered together to adapt to cardboard of different thicknesses. The groove 207 can be used for the fixed rod 205 to be engaged during the lifting and lowering process to prevent the top of the receiving rack 2 from obstructing the fixed rod 205. When the narrow conveyor belt 201 drives the cardboard to move, the cardboard... One end of the plate first contacts the roller 217 at the bottom of the adjusting plate 214. The adjusting plate 214 is squeezed by the cardboard and rotates slightly upward. The spring column 215 begins to contract and store elastic potential energy. The cardboard continues to move until the die template, which has been cut in the middle, contacts the roller 217. When the cutting creates a weak edge (such as burrs or slight adhesion) in the die template, the stress concentration point is broken through when it is squeezed by the adjusting plate 214, thus separating the die template from the cardboard. The die template falls and stacks on the... At the bottom of the receiving rack 2, the cardboard continues to move and falls to one side of the receiving rack 2 under the drive of the narrow conveyor belt 201. The sliding column 210 moves along the bottom of the bridge frame 209, which can adjust the position of the adjusting plate 214 to accommodate cardboard with different die shapes (such as square, rectangular, trapezoidal, etc.). The fastening nut 213 is rotated and lowered by screwing with the screw 211. The fastening nut 213 is in contact with the bridge frame 209, and the position of the sliding column 210 can be fixed by the friction between the two.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
