Description

Technical Field

[0001] This utility model relates to the field of collection device technology, specifically to a waste collection vehicle for a flatbed die-cutting machine. Background Technology

[0002] Flatbed die-cutting machines are key equipment in the post-printing processing of paper products such as packaging boxes, trademarks, and paper cards. Their main function is to use precision molds to punch and creasing (press) printing materials such as cardboard and corrugated board, thereby obtaining semi-finished workpieces with specific shapes and fold lines. These workpieces can then be folded and glued into the final packaging product through subsequent processes.

[0003] Die-cutting inevitably generates waste. The mechanism is as follows: to maximize material utilization, multiple unfolded images (blanks) of packaging boxes are typically arranged (nested) closely on a large-format substrate. During die-cutting, a die-cutting plate equipped with high-strength steel blades and crimping blades acts under immense pressure on the substrate, cutting it into individual blank units. However, the material outside the blank units, as well as the "skeleton" parts used for connection and fixation between units (also known as "bridges" or "edge material"), become the parts that need to be discarded—the die-cutting waste. This waste is often in the form of long strips.

[0004] Currently, most mainstream flatbed die-cutting machines employ automated waste removal systems to eliminate the aforementioned waste. This system typically includes an ejector mechanism that matches the die-cutting plate and a set of ducts connected to a high-pressure air source. After die-cutting, the ejector mechanism lifts the entire die-cut sheet, initially separating the finished blank from the waste skeleton. Subsequently, high-pressure airflow is forcefully directed through nozzles in the ducts at the waste skeleton, using the kinetic energy of the airflow to rapidly blow the waste away from the machine and discharge it through pre-set pipes or guide channels.

[0005] Although traditionally airflow can be used to discharge waste from inside the machine through pipes, the discharged waste currently piles up directly on the ground, making it impossible to collect the discharged waste in a centralized manner. The scattered waste can easily cause people to slip and fall, thus affecting safe production. Utility Model Content

[0006] The purpose of this utility model is to provide a waste collection vehicle for a flatbed die-cutting machine, addressing the shortcomings and deficiencies of existing technologies.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a waste collection vehicle for a flatbed die-cutting machine, comprising a frame, a receiving opening at the front end of the frame for receiving waste, an airflow mesh plate on the back of the frame for discharging waste after airflow blows it into the receiving opening and preventing waste from passing through, and an interception component on the frame located within the receiving opening for intercepting and collecting waste when airflow blows it into the receiving opening, so as to prevent waste from clogging the airflow mesh plate.

[0008] A further improvement is that the interception component includes a connecting crossbar disposed on the frame within the receiving opening, and a plurality of interception bars equidistantly disposed on the connecting crossbar.

[0009] A further improvement is that each of the aforementioned interceptor bars is equidistant along the length of the connecting crossbar.

[0010] A further improvement is that each of the aforementioned intercepting rods is symmetrically and fixedly installed at the upper and lower ends of the connecting crossbar.

[0011] A further improvement is that each of the aforementioned interceptor bars has an arc-shaped interceptor plate symmetrically arranged at both ends, with one end of the arc-shaped interceptor plate fixedly mounted on the interceptor bar.

[0012] Further benefits: When intercepting waste, the arc-shaped interceptor plate can further improve the interception effect of waste by converging and intercepting it in an arc shape, and reduce the phenomenon of waste passing through the airflow mesh plate.

[0013] A further improvement is that: several arc-shaped interceptor plates are provided, and each arc-shaped interceptor plate is arranged longitudinally at equal intervals on each interceptor bar.

[0014] A further improvement is that the lower end of the frame is equipped with four omnidirectional wheels.

[0015] A further improvement is that the airflow mesh plate is made of stainless steel.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are as follows: Before the die-cutting machine processes the packaging box, the frame is placed on the opposite side of the pipe, and the receiving opening faces the outlet of the pipe. When the airflow blows the waste material out of the pipe during the die-cutting process, the waste material enters the frame through the receiving opening and is collected. After the airflow blows the waste material into the receiving opening, the airflow mesh plate allows the airflow to be discharged and prevents the waste material from passing through. It can play a role in depressurizing the airflow and prevent the contained waste material from flying out of the frame due to the disturbance of the airflow. After the waste material enters the receiving opening, the waste material will first contact the interception component to intercept the waste material, so as to prevent the waste material from sticking to the airflow mesh plate and forming a blockage. This achieves the functions of waste material collection and airflow depressurization, improves the waste material collection effect, and the discharged waste material can be collected in a concentrated manner. It is not easy for scattered waste material to cause personnel to slip and fall, and it is not easy to affect safe production. Attached Figure Description

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0021] See Figures 1 to 3 As shown, the technical solution adopted in this specific embodiment is: a waste collection vehicle for a flatbed die-cutting machine, including a frame 1, a receiving opening 2 opened at the front end of the frame 1 for waste to enter and contain, an airflow mesh plate 3 set on the back of the frame 1 for airflow to discharge and prevent waste from passing through after the airflow blows the waste into the receiving opening 2, and an interception component set on the frame 1 located in the receiving opening 2 for intercepting and collecting the waste when the airflow blows the waste into the receiving opening 2, so as to prevent the waste from clogging the airflow mesh plate 3.

[0022] The airflow mesh plate 3 has several air holes for airflow to pass through. The diameter of the air holes in the airflow mesh plate 3 can be smaller than the width of the waste material, and the shape of the air holes is not limited, to prevent unintercepted waste material from passing through the air holes in the airflow mesh plate 3. The airflow mesh plate 3 is installed on the frame 1 by welding through an opening that is the same size as or slightly larger than the frame 1 by 1-10 mm. The frame 1 is selected as a stainless steel frame 1.

[0023] The interception assembly includes a connecting crossbar 4 disposed on the frame 1 within the receiving opening 2, and a plurality of intercepting rods 5 equidistantly disposed on the connecting crossbar 4. The connecting crossbar 4 can be a single rod, positioned in the middle of the frame 1. In this case, the intercepting rods 5 are arranged vertically, forming a staggered arrangement with the connecting crossbar 4 within the receiving opening 2. Figure 1 and Figure 3 As shown, two connecting crossbars 4 can also be used. In this case, the two connecting crossbars 4 divide the frame 1 into three equidistant spaces, with the connecting rods located in each space, and the distance between the upper and lower ends of the intercepting rods 5 being close to each other. A gap is formed between the connecting crossbars 4 and the airflow mesh plate 3. This gap is set to be greater than the maximum length of common waste material, preferably 1.2 to 2 times the maximum length of common waste material, typically between 1 and 3 meters. This setting ensures that the intercepted waste material cannot contact and block the airflow mesh plate 3 within its own length range. The left and right ends of the connecting crossbars 4 are fixed to the frame 1 by welding, or can be disassembled using bolts. The intercepting rods 5 are fixed to the connecting crossbars 4 by welding or bonding.

[0024] Each of the aforementioned interceptor bars 5 is equidistantly arranged along the length direction of the connecting crossbar 4.

[0025] Each of the aforementioned intercepting rods 5 is symmetrically fixed at the upper and lower ends of the connecting crossbar 4.

[0026] Each of the intercepting rods 5 has symmetrically arranged arc-shaped intercepting plates 6 at both ends, with one end of the arc-shaped intercepting plate 6 fixedly attached to the intercepting rod 5. Arc-shaped intercepting plates 6 are arranged at intervals between each intercepting rod 5 to intercept waste material within that interval. To improve the waste interception effect, the height of the arc-shaped intercepting plates 6 can be adjusted to increase the interception area and enhance the interception effect. The arc-shaped intercepting plates 6 are fixed to the intercepting rods 5 by welding or bonding.

[0027] Several arc-shaped interceptor plates 6 are provided, and each arc-shaped interceptor plate 6 is arranged longitudinally at equal intervals on each interceptor bar 5.

[0028] The lower end of the frame 1 is provided with four casters 7. The casters 7 are all movable casters with brakes, which can fix the position of the frame 1 while allowing it to move, and prevent the airflow from moving the frame 1.

[0029] The airflow mesh plate 3 is made of stainless steel. Its corrosion resistance and high mechanical strength ensure that it maintains structural integrity and unobstructed airflow even under long-term impact from waste materials and the workshop environment, thus extending the equipment's service life. The working principle of this utility model is as follows: The core of this utility model lies in the synergistic solution to the problems of airflow depressurization and fine interception of waste materials. Before the die-cutting machine processes the packaging box, the frame 1 is placed opposite the pipe, with the receiving opening 2 facing the outlet of the pipe and the caster 7 braked. When the airflow blows the waste material out of the pipe during the die-cutting process, the waste material enters the frame 1 through the receiving opening 2 and is collected. After entering, the waste material first collides with the connecting crossbar 4 and several intercepting bars 5. The connecting crossbar 4 and the intercepting bars 5 constitute the main primary interception structure, which initially intercepts the waste material. The arc-shaped intercepting plate 6 further increases the interception area and guides and gathers the waste material through its arc structure, effectively preventing the waste material from rushing towards the airflow in a straight line. The mesh plate 3 reduces the phenomenon of waste sticking to the airflow mesh plate 3 and causing blockage. After the airflow loses the waste carrier and is blocked by the interception component, the kinetic energy is greatly reduced, and then it is evenly discharged through the air holes on the airflow mesh plate 3, thereby achieving the functions of waste collection and airflow depressurization. Since the diameter of the air hole is smaller than the width of the minimum waste, the waste is completely blocked in the frame 1. During this process, the airflow can be depressurized smoothly, and its reaction force on the frame 1 is reduced to an extremely low level. Thus, with the assistance of the universal wheel 7 brake, the phenomenon of the collection vehicle moving or tipping over is completely eliminated. Through the coordinated work of the above components, this utility model realizes the centralized and efficient collection of waste, avoids the risk of slipping and production interruption caused by the scattering of waste, and significantly improves the safety production efficiency and the convenience of waste management.
