Description

Technical Field

[0001] This utility model relates to the field of tobacco processing equipment technology, and in particular to a cleaning device for the guide strip of a shredder. Background Technology

[0002] Guide strips are widely used in the cutting systems of tobacco shredders, primarily to guide the cut tobacco shreds downwards. The guide strip includes a volume groove, a transition arc surface, a discharge surface, and a cutting edge. It is fixedly mounted on the cutter roller, which has side plates on both sides, and the roller is rotatably connected between these plates. During shredding, the tobacco shreds cut by the rotating cutter roller are guided by the cutting edge and guide surface of the guide strip to the discharge port and vibrating trough below. In actual production, tobacco powder and impurities easily adhere to the guide strip and the cutting edge of the cutter roller. The tobacco oil contained in the tobacco sheets also adheres and accumulates on the cutting edge of the guide strip, drying to form hard, strip-shaped tobacco residue, which falls off and mixes into the tobacco shreds in the vibrating trough below. Because this residue reforms after falling off, this process repeats itself, resulting in a large amount of residue mixing into the tobacco shreds. This not only reduces the shredding quality but may also affect the stability of the equipment operation. Utility Model Content

[0003] The purpose of this invention is to provide a cleaning device for the guide strip of a shredder, which solves the problem of easy dirt accumulation on the guide strip in the prior art.

[0024] like Figure 1-7 As shown in the figure, this utility model embodiment proposes a cleaning device for the guide strip of a shredder, including an air blowing mechanism and an external cleaning mechanism. The air blowing mechanism is used to clean tobacco powder and impurities adhering to the guide strip 3, while the external cleaning mechanism is used to clean stubborn tobacco residue such as tar. This utility model cleans the guide strip 3 in two ways: firstly, by modifying the structure of the guide strip 3 itself and then cleaning it in real time by air blowing; secondly, by designing an external cleaning mechanism corresponding to the modified guide strip 3, it can effectively prevent dirt accumulation on the guide strip 3, thereby improving the stability and shredding quality of the shredder.

[0025] To facilitate understanding of this embodiment, as Figure 6As shown, the guide bar 34 includes a volume groove 31, a transition arc surface 32, a throwing surface 33, and a cutting edge 34. The guide bar 3 is fixedly installed on the cutter roller 11. Both sides of the cutter roller 11 are provided with side plates 10. The cutter roller 11 is rotatably connected between the two side plates 10. The guide bar 3 and the side plates 10 are in clearance fit.

[0026] One end face of the guide strip 3 is provided with a first air passage 35 extending along the length of the guide strip 3 and opening towards one side of the end face. The side wall of the volume groove 31 is provided with a plurality of compressed air holes 36 spaced along the length of the guide strip 3. Each compressed air hole 36 communicates with an air passage. A second air passage is opened on the side plate 10. When the guide strip 3 rotates, the first air passage 35 on the guide strip 3 can align and communicate with the second air passage. The blowing mechanism includes an air guide pipe 1 and a straight-through solenoid valve 2. One end of the air guide pipe 1 communicates with the second air passage, and the other end communicates with an external air source. In this embodiment, the air source can be the air source provided by the shredder, or an additional electric air pump can be added specifically for cleaning the guide strip 3. The straight-through solenoid valve 2 is installed on the air guide pipe 1. According to the working state of the shredder and the properties of the tobacco, the opening and closing of the compressed air holes 36 and the air flow rate can be automatically adjusted by the straight-through solenoid valve 2 to achieve the optimal cleaning effect.

[0027] A one-way valve is installed in the compressed air port 36. Since cleaning is not a continuous process, the one-way valve in the compressed air port 36 prevents soot from entering the first air passage 35 through the compressed air port 36.

[0028] In fact, the one-way valve can be a spring and a ball. The diameter of the compressed air hole 36 gradually increases from the direction of airflow. The two ends of the spring are fixedly connected to the side wall of the compressed air hole 36 and the ball, respectively. The spring makes the ball tend to seal the compressed air hole 36. When the air source enters the compressed air hole 36 through the air guide pipe 1, the second air passage, and the first air passage 35, the air pressure overcomes the spring force and pushes the ball open to blow it out of the compressed air hole 36. In this embodiment, the compressed air port 36 is a stepped port. The end of the compressed air port 36 near the volume groove 31 is a large-diameter section, and the end near the first air passage 35 is a small-diameter section. The one-way valve includes a mounting bracket 4 and an elastic plate 5. The mounting bracket 4 is cross-shaped, and its four ends are fixedly connected to the sidewall of the small-diameter section of the compressed air port 36 near the shoulder of the port. The elastic plate 5 is located at the shoulder of the compressed air port 36, and it matches the large-diameter section of the compressed air port 36. The outer side of the elastic plate 5 is flush with the sidewall of the volume groove 31 to prevent soot from entering the compressed air port 36. The inner side of the elastic plate 5 is fixedly connected to the mounting bracket 4, and the cross-shaped mounting bracket 4 can provide stable support for the elastic plate 5.

[0029] In this embodiment, the elastic sheet 5 is a disc-shaped thin sheet, preferably made of polytetrafluoroethylene (PTFE) or perfluororubber. Both of these materials have excellent chemical stability, corrosion resistance, high lubricity and non-stickiness, and good anti-aging resistance. They also exhibit elasticity when in sheet form. Since the outer side of the elastic sheet 5 is flush with the sidewall of the volume groove 31, it does not affect the normal use of the guide strip 3. At the same time, the tobacco will not adhere to the elastic sheet 5 when passing through the sidewall of the volume groove 31.

[0030] In the above embodiment, when the first air passage 35 and the second air passage are aligned and connected, the direct-flow solenoid valve 2 allows airflow to enter the second air passage, the first air passage 35, and the compressed air hole 36. The gas pressure causes the edge of the disc-shaped elastic sheet 5 to bend outward. The greater the gas flow rate, the greater the bending degree of the elastic sheet 5. At this time, the gas can flow past the edge of the elastic sheet 5 to clean the guide wire strip 3 and the cutting edge 34 of the cutter roller 11 in real time. When the direct-flow solenoid valve 2 disconnects the air source, the gas stops, and the disc-shaped elastic sheet 5 returns to its initial shape due to its own elasticity.

[0031] The external cleaning mechanism includes a handle 6, a roller brush 7, and a drive motor 9. The roller brush 7 is rotatably mounted on one end of the handle 6, and the drive motor 9 is located inside the handle 6. The roller brush 7 is connected to the drive motor 9, and the axis of the roller brush 7 is perpendicular to the axis of the handle 6. In this embodiment, there are two roller brushes 7. A rotating shaft is rotatably mounted on the front end of the handle 6 via a bearing. The axis of the rotating shaft is perpendicular to the axis of the handle 6, and both ends of the rotating shaft protrude outside the handle 6. The two ends of the rotating shaft are fixedly connected to two roller brushes 7, respectively. The axis of the roller brush 7 is collinear with the axis of the rotating shaft. The handle 6 has a cavity inside, and the drive motor 9 is fixedly mounted in the cavity by bolts. The output end of the drive motor 9 is connected to the rotating shaft via a gear and chain mechanism. A protective shell 8 is fitted over the roller brush 7 to prevent cleaning fluid from splashing during cleaning. The drive motor 9 can drive the rotating shaft and the roller brush 7 to rotate.

[0032] In this embodiment, the external cleaning mechanism is handheld and used to clean the guide strip 3 of this application. The size of the roller brush 7 is exactly matched with the volume groove 31 of the guide strip 3. Since the contact surface between the guide strip 3 and the tobacco shreds of this application is designed with multiple elastic pieces 5, it is not advisable to use a traditional scraper to remove the tobacco residue, as the elastic pieces 5 are easily damaged when the scraper removes the tobacco residue. Therefore, the external cleaning mechanism designed in this application drives the rotating shaft through the drive motor 9 to rotate the roller brush 7, thereby achieving a gentle cleaning method for cleaning the guide strip 3. The bristles of the roller brush 7 will not cause any damage to the guide strip 3 and the elastic pieces 5, which is safe and reliable. At the same time, the rotation of the entire roller brush 7 achieves surface cleaning, which not only has a large cleaning area but is also highly efficient and fast, greatly improving the efficiency of cleaning and maintaining the guide strip 3 of the tobacco shredder.

[0033] Working principle:

[0034] The air source is connected via a direct-flow solenoid valve 2. When the first air passage 35 and the second air passage are aligned and connected, gas enters the first air passage 35 and the compressed air hole 36. Under the action of air pressure, the edge of the elastic sheet 5 bends outward, and the gas is blown out from the compressed air hole 36, cleaning the guide wire strip 3 in real time. After a period of use, the dirt on the guide wire strip 3 is moistened by spraying water. By holding the handle 6, the drive motor 9 is started, and the roller brush 7 extends into the volume groove 31 to clean the stubborn soot adsorbed inside the guide wire strip 3. When one guide wire strip 3 is cleaned, the cutter roller 11 is rotated to move the next guide wire strip 3 to a position that is convenient for the operator to clean, and the cleaning continues.

[0035] The shredder guide bar cleaning device provided by this utility model can effectively prevent dirt buildup on the guide bar 3, improving the stability and shredding quality of the shredder. Furthermore, the device has a simple airflow cut-off structure, is easy to use, greatly reducing operating difficulty and maintenance intensity, and conforms to the trend of modern tobacco processing equipment towards intelligence and automation.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
