Description

Technical Field

[0001] This utility model belongs to the field of pneumatic tool technology, and specifically relates to a waste collection structure for a pneumatic engraving machine. Background Technology

[0002] A pneumatic engraving machine is an industrial marking device powered by compressed air. It consists of three parts: a controller, a printer, and a computer. It is mainly used for permanent marking printing on automotive and motorcycle parts, metal pipes, military products, hardware tools, and other fields. The waste collection structure used in pneumatic engraving machines is a structure that collects the waste and debris generated during the engraving process.

[0003] However, the waste collection structure of traditional pneumatic engraving machines is difficult to adapt to the layout of the engraving machine base, and it is not easy to avoid the blind spots of collection caused by the base. The collection efficiency of the waste generated by engraving is low, and a large amount of waste remains on the worktable. Some structures may also occupy the engraving operation space or interfere with the clamps and engraving heads, which not only affects the clamps' fixing effect on the workpiece, but may also interfere with the normal engraving accuracy of the engraving machine. It is difficult to balance the collection effect and the original performance of the equipment. At the same time, waste can easily enter the suction part, causing blockage or wear, resulting in frequent failures of the suction function and unstable operation. Cleaning requires disassembling the core components of the equipment, which is cumbersome and inconvenient, and greatly increases the maintenance time.

[0004] To address the problems mentioned in the background above, a waste collection structure for a pneumatic engraving machine is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a waste collection structure for a pneumatic engraving machine, which has the advantages of waste adsorption and easy cleaning.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a waste collection structure for a pneumatic engraving machine, comprising a shell, a through groove being provided around the top of the shell near the center, a dust collection chamber being provided inside the shell, an air suction pipe being provided at the bottom of the dust collection chamber, a material suction machine being connected to the end of the air suction pipe away from the dust collection chamber, and the surface of the material suction machine being embedded in the bottom of the shell, an exhaust pipe being connected to the left side of the material suction machine, and the left side of the exhaust pipe penetrating the left side of the shell, a filter screen being embedded in the bottom of the dust collection chamber, and a cleaning mechanism being provided on the front of the shell.

[0007] The above technical solution works as follows: After the suction machine starts, it creates negative pressure in the dust collection chamber through the suction pipe. The debris generated during the engraving process will enter the dust collection chamber through the through-slot on the top of the outer shell under the negative pressure. The filter screen at the bottom of the dust collection chamber will trap the debris and prevent it from entering the suction machine with the airflow. The filtered air is then sucked in by the suction machine and discharged from the outer shell through the exhaust pipe, thus completing the collection of debris and the circulation of airflow. The debris on the surface of the pneumatic engraving machine and the fixture can be manually swept away by a brush to the vicinity of the through-slot and collected together when the suction machine is working. This solution can effectively adapt to the layout of the engraving machine base, avoid the collection blind spots formed by the base and the fixture, and ensure that the debris can be guided to the collection area in an orderly manner. Through the combination of active adsorption and auxiliary cleaning, various debris generated during the engraving process can be collected efficiently, reducing the residue of debris in the gaps of the equipment and the worktable. This does not interfere with the normal engraving accuracy of the engraving machine and the fixing function of the fixture on the workpiece, and takes into account both the collection effect and the original performance of the equipment.

[0008] The present invention is further configured such that the cleaning mechanism includes a door, the door is located on the front of the outer shell and is rotatably connected by a hinge, sliders are welded on both sides of the dust collection bin, and grooves are provided on both sides of the inner wall of the outer shell, and the interior of the grooves is slidably connected to the surface of the sliders.

[0009] The above technical solution employs a cleaning mechanism. During cleaning, the door on the front of the outer casing is first opened to expose the internal dust collection chamber. Then, the dust collection chamber is pulled outwards, and the sliders on both sides slide synchronously along the grooves on the inner wall of the outer casing, allowing the dust collection chamber to be smoothly removed from the casing for cleaning of internal debris and waste. After cleaning, the sliders of the dust collection chamber are aligned with the grooves and pushed in. After the dust collection chamber is reset, the door can be closed by rotating it in the opposite direction, completing the entire cleaning operation. This effectively traps debris and waste, preventing it from entering the suction components and causing blockages or wear, ensuring stable operation of the suction function. Cleaning does not require disassembling the core components of the equipment, making the operation convenient and efficient, significantly reducing maintenance time. It ensures that the debris and waste collection process does not interfere with the engraving operation of the engraving machine or the function of the clamp fixing the workpiece, balancing collection reliability and the original performance of the equipment.

[0010] The present invention is further provided that a mounting groove is provided at the center of the top of the outer casing.

[0011] The above technical solution involves setting up a mounting slot to install a base for the pneumatic engraving machine.

[0012] The present invention is further provided with a mesh cover at the top of the through groove.

[0013] The above technical solution, by setting up a mesh cover, can prevent large particles of waste from entering the channel and clogging the filter screen.

[0014] The present invention is further configured such that a dust cover is bolted to the left side of the exhaust pipe.

[0015] The above technical solution employs a dust cover made of metal, which is bolted on and provides both dust protection and noise reduction.

[0016] The present invention is further provided that a sealing strip is embedded in the surface of the door.

[0017] The above technical solution, by setting a sealing strip and using an interference fit, has a sealing function and can prevent the leakage of debris and waste inside the dust collection box.

[0018] The present invention is further configured such that the top edge of the outer casing is a ramp.

[0019] The above technical solution is adopted: by setting it as a ramp, it can prevent debris and waste from jumping out. The debris and waste that come into contact with the ramp fall to the top of the shell by gravity and can be collected later.

[0020] The present invention is further configured such that a handle is bolted to the front of the door.

[0021] The above technical solution incorporates a handle, making it easy to open the door.

[0022] In summary, this utility model has the following beneficial effects: 1. This utility model can effectively adapt to the layout of the engraving machine base, avoid the collection blind spots formed by the base obstruction and the clamp, and ensure that the debris and waste can be guided to the collection area in an orderly manner. Through the combination of active adsorption and auxiliary cleaning, it can efficiently collect various debris and waste generated during the engraving process, reduce the residue of debris and waste in the gaps of the equipment and the worktable, and not interfere with the normal engraving accuracy of the engraving machine and the fixing function of the clamp on the workpiece, thus taking into account both the collection effect and the original performance of the equipment. 2. This utility model can effectively intercept debris and waste materials, preventing them from entering the suction component and causing blockage or wear, thus ensuring the stable operation of the suction function. There is no need to disassemble the core components of the equipment during cleaning, making the operation convenient and efficient, and significantly reducing maintenance time. It can ensure that the debris and waste material collection process does not interfere with the engraving operation of the engraving machine and the function of the clamp to fix the workpiece, thus taking into account the reliability of collection and the original performance of the equipment.

A through groove 2 is formed around the top of the housing 1 near the center. A dust collection chamber 3 is located inside the housing 1. An air suction pipe 4 is located at the bottom of the dust collection chamber 3. One end of the air suction pipe 4, away from the dust collection chamber 3, is connected to a material suction machine 5. The surface of the material suction machine 5 is embedded in the bottom of the housing 1. An exhaust pipe 6 is connected to the left side of the material suction machine 5, and the left side of the exhaust pipe 6 penetrates the left side of the housing 1. A filter screen 7 with a pore size of 0.8-1.5mm is embedded in the bottom of the dust collection chamber 3. A cleaning... After the suction machine 5 starts, it creates a negative pressure in the dust collection chamber 3 through the suction pipe 4. The debris generated during the engraving process will enter the dust collection chamber 3 through the through groove 2 at the top of the outer shell 1 under the action of negative pressure. The filter screen 7 at the bottom of the dust collection chamber 3 will trap the debris and prevent it from entering the suction machine 5 with the airflow. The filtered air is then sucked in by the suction machine 5 and discharged from the outer shell 1 through the exhaust pipe 6, thus completing the collection of debris and the circulation of airflow. The debris on the surface of the pneumatic engraving machine and the fixture can be manually swept away by a brush to the vicinity of the through groove 2 and collected together when the suction machine 5 is working.

[0027] refer to Figure 2 , Figure 3 The top center of the outer casing 1 has a mounting groove 11, which allows the base of the pneumatic engraving machine to be installed.

[0028] refer to Figure 1 , Figure 2 , Figure 3 A mesh cover 12 is provided at the top of the channel 2. By providing the mesh cover 12, large particles of waste can be prevented from entering the channel 2 and clogging the filter screen 7. The mesh cover 12 has a hole diameter of 3-5mm.

[0029] refer to Figure 3 The left side of the exhaust pipe 6 is bolted with a dust cover 13. The dust cover 13 is made of metal and is bolted on, and has the functions of dust prevention and noise reduction.

[0030] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 The top edge of the outer shell 1 is set as a ramp. By setting it as a ramp, it can prevent debris and waste from jumping out. The debris and waste that come into contact with the ramp falls to the top of the outer shell 1 by gravity and can be collected later.

[0031] Example 2: refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 A waste collection structure for a pneumatic engraving machine includes a cleaning mechanism comprising a door 8, which is located on the front of a housing 1 and is rotatably connected by a hinge. Slider 9s are welded to both sides of a dust collection chamber 3. Slide grooves 10 are provided on both sides of the inner wall of the housing 1, and the interior of the slide grooves 10 is slidably connected to the surface of the slider 9s. During cleaning, the door 8 on the front of the housing 1 is first opened to expose the dust collection chamber 3 inside. Then, the dust collection chamber 3 is pulled outwards, and the slider 9s on both sides slide synchronously along the slide grooves 10 on the inner wall of the housing 1, allowing the dust collection chamber 3 to smoothly detach from the housing 1 for cleaning internal debris and waste. After cleaning, the slider 9s of the dust collection chamber 3 are aligned with the slide grooves 10 and pushed in. After the dust collection chamber 3 is reset, the door 8 can be closed by rotating it in the opposite direction, completing the entire cleaning operation.

[0032] refer to Figure 1 , Figure 4 The surface of door 8 is embedded with a sealing strip 14. By setting the sealing strip 14 and fitting it with an interference fit, it has a sealing function and can prevent the leakage of debris and waste inside the dust collection box. The material is silicone rubber.

[0033] refer to Figure 1 , Figure 4 A handle 15 is bolted to the front of door 8, which makes it easy to open door 8.

[0034] The material suction machine, model 5, is Exair Model 6084 2. Its surface and bottom are embedded within the casing, forming a unified design that avoids occupying additional external space. It connects to the bottom of the dust collection chamber via a suction pipe, which provides a negative pressure channel for drawing air from the chamber. The left side connects to an exhaust pipe, which extends through the left side of the casing, expelling the air drawn in by the suction machine and filtered by the dust collection chamber's filter to the outside, creating an airflow circulation. Upon startup, the suction pipe creates a negative pressure environment within the dust collection chamber, causing engraving debris to enter through a slot at the top of the casing. Simultaneously, it receives filtered clean air from the dust collection chamber and exhausts it through the exhaust pipe. This, combined with the dust collection chamber and filter, achieves a closed-loop debris collection process of "adsorption-filtration-exhaust."

[0035] Brief description of operation: After the suction machine 5 starts, a negative pressure is formed in the dust collection chamber 3 through the suction pipe 4. The debris and waste generated during the engraving process will enter the dust collection chamber 3 through the through groove 2 at the top of the outer shell 1 under the action of negative pressure. The filter screen 7 at the bottom of the dust collection chamber 3 will trap the debris and waste, preventing it from entering the suction machine 5 with the airflow. The filtered air is then sucked in by the suction machine 5 and discharged from the outer shell 1 through the exhaust pipe 6, thus completing the collection of debris and waste and the circulation of airflow. The debris and waste on the surface of the pneumatic engraving machine and fixture can be brushed away. The dust collected manually near the channel 2 is collected together with the suction machine 5 when it is working. During cleaning, first open the door 8 on the front of the outer shell 1 to expose the dust collection bin 3 inside. Then pull the dust collection bin 3 outward. The sliders 9 on both sides will slide synchronously along the sliding groove 10 on the inner wall of the outer shell 1, so that the dust collection bin 3 can be smoothly removed from the outer shell 1 to clean the internal debris and waste. After cleaning, align the sliders 9 of the dust collection bin 3 with the sliding groove 10 and push them in. After the dust collection bin 3 is reset, turn the door 8 in the opposite direction to close it, and the entire cleaning operation is completed.

[0036] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
