Description

Technical Field

[0001] This invention relates to the field of rubber product processing equipment technology, and more specifically, to a cylindrical grinding machine for rubber manufacturing that facilitates waste collection. Background Technology

[0002] The external cylindrical grinding machine used in rubber manufacturing generates a large amount of loose, easily dispersed, and sticky rubber debris during the grinding process, and its effective handling has been a long-standing challenge for the industry.

[0003] First, these flying debris severely pollute the workshop environment, endangering the respiratory health of operators and easily penetrating precision moving parts such as machine tool guideways and lead screws, leading to abnormal wear and precision deterioration. Furthermore, due to the characteristics of rubber, the debris often re-adheres to the surface of the workpiece being processed after being randomly diffused in the grinding zone under the influence of centrifugal force and airflow, directly affecting the dimensional accuracy and surface finish of the workpiece and accelerating grinding wheel clogging.

[0004] Furthermore, existing dust removal solutions mostly rely on external dust hoods in a single direction, which are inefficient at capturing lightweight, statically charged rubber shavings and have obvious airflow dead zones.

[0005] More importantly, the sucked-in debris tends to adhere to the dust collection pipes and the inner walls of the container. Regular cleaning requires disassembling parts, which is a cumbersome process and results in long downtime, severely restricting the equipment's continuous operation capability and production efficiency. Summary of the Invention

[0006] To address the problems existing in the prior art, this invention provides a rubber-manufactured cylindrical grinding machine that facilitates waste collection. This solves the problem mentioned in the background art where the flying debris seriously pollutes the workshop environment, not only endangering the respiratory health of operators but also easily intruding into precision moving parts such as machine tool guideways and lead screws, leading to abnormal wear and precision degradation. Furthermore, due to the characteristics of rubber, the debris often re-adheres to the surface of the workpiece being processed after being disorderly diffused by centrifugal force and airflow in the grinding zone, directly affecting the dimensional accuracy and surface finish of the workpiece and accelerating grinding wheel clogging.

[0008] The present invention is further configured such that the cover cleaning structure includes a first sliding rod, and a first arc-shaped sliding groove is provided on both sides of the protective cover. Both sets of the first arc-shaped sliding grooves are slidably fitted with the first sliding rod. A limiting frame that is slidably fitted with the protective cover is provided on both sides of the first sliding rod. A first scraper is provided on the first sliding rod, and a handle is provided on one set of the two sets of limiting frames. Through the sliding cooperation between the first slide rod and the first arc-shaped slide groove, the first scraper can achieve smooth reciprocating motion along a specific trajectory on the inner wall of the protective cover.

[0009] The present invention is further configured such that a rubber sleeve is provided on the handle; The rubber sleeve on the handle improves the gripping feel for the operator, providing anti-slip and shock absorption, thus enhancing the comfort and safety of manual cleaning operations and reflecting a human-centered design.

[0010] The present invention is further configured such that the mounting structure includes two sets of fixing blocks, the main body of the device is provided with two sets of mounting sliders, the collection box is connected to the two sets of fixing blocks, and the two sets of fixing blocks are respectively provided with mounting grooves that slide and fit with the two sets of mounting sliders. This structure enables the rapid installation and removal of the collection box through the sliding cooperation of the fixing block, the mounting groove, and the mounting slider on the main body of the equipment.

[0011] The present invention is further configured such that the inner wall cleaning structure of the box includes a first slider, a second arc-shaped groove is provided on one side of the dust collection box and slides in a sliding fit with the first slider, a second scraper is provided on one side of the first slider, a limiting plate is provided on one side of the first slider, an arc-shaped handle is provided on the limiting plate, and a discharge port is provided on one side of the dust collection box. This structure is key to solving the problem of cleaning the inside of the dust collection box. The first slider slides in the second arc-shaped groove, which drives the second scraper to scrape the inner wall of the dust collection box. The arc-shaped handle provides an external operating fulcrum, so that the cleaning work can be completed without opening or disassembling the dust collection box.

[0012] The present invention is further configured such that a sealing arc-shaped strip of a sliding sleeve is provided on the second arc-shaped groove; The sealing arc strip ensures the dust collection box remains sealed even when it has not been cleaned, preventing insufficient airflow from the centrifugal fan due to the second arc groove.

[0013] The present invention is further configured such that a storage box is provided on one side of the dust collection box and fixed thereto by bolts; The storage box serves as a temporary storage container for the final waste, catching the debris falling from the discharge port.

Beneficial effects

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention physically surrounds the grinding area with a detachable protective cover, effectively blocking the disorderly splashing of debris, protecting the health of operators and preventing debris from entering the precision parts of the machine tool. Its inner wall cleaning structure is easy to maintain and ensures long-term effective protection. At the same time, large particles of debris are guided to the sliding collection box below, realizing the primary classification and convenient cleaning of waste. 2. This invention utilizes four sets of ventilation pipes to guide the suction of the dust collection box to different key locations inside the protective cover, forming a three-dimensional suction field that covers the main flying trajectory of debris. This design overcomes the defect of dead airflow in a single dust collection port, and can capture lightweight, electrostatic rubber debris from multiple directions in a timely manner, making dust removal more thorough and reducing the secondary adhesion of debris to workpieces and grinding wheels from the source. 3. To address the problem of debris easily adhering to the inner wall of the dust collection components, this invention integrates an inner wall cleaning structure into the dust collection box. Operators do not need to disassemble any components; they only need to operate the arc-shaped handle from the outside to drive the scraper to remove the accumulated debris from the inner wall, which then falls into the storage box through the discharge port. This design enables rapid and convenient online cleaning of the dust collection system, greatly reducing maintenance downtime and ensuring the production efficiency and continuous operation capability of the equipment.

A first scraper 14 is provided on the first slide rod 11, and a handle 15 is provided on one of the two sets of limiting frames 13. Through the sliding cooperation between the first slide bar 11 and the first arc-shaped slide groove 12, the first scraper 14 achieves a smooth reciprocating motion along a specific trajectory on the inner wall of the protective cover 2. This structure is ingeniously designed and reliable in operation. It can effectively scrape away debris adhering to the inner wall of the protective cover 2, preventing debris accumulation from affecting vision, reducing the protective effect, or causing secondary pollution. The setting of the limit frame 13 ensures the stability of the slide bar movement, and the handle 15 provides a convenient manual operation interface.

[0023] In this embodiment, a rubber sleeve 16 is provided on the handle 15; The rubber sleeve 16 installed on the handle 15 improves the grip feel for the operator, and plays a role in anti-slip and shock absorption, thereby improving the comfort and safety of manual cleaning operations.

[0024] In this embodiment, the mounting structure includes two sets of fixing blocks 17, and two sets of mounting sliders 18 are provided on the main body of the device. The collection box 4 is connected to the two sets of fixing blocks 17, and the two sets of fixing blocks 17 are respectively provided with mounting grooves 19 that slide and fit with the two sets of mounting sliders 18. This structure enables the quick installation and removal of the collection box 4 through the sliding cooperation of the fixing block 17, the mounting groove 19 and the mounting slider 18 on the main body of the equipment. When large particles of waste accumulated in the collection box 4 need to be cleaned, the operator can easily pull them out along the groove, empty the waste, and then push them back to their original position to lock them. The whole process does not require tools, which greatly simplifies daily maintenance operations and improves the convenience of using the equipment.

[0025] In this embodiment, the inner wall cleaning structure of the box includes a first slider 20, a second arc-shaped groove 21 that slides and fits with the first slider 20 is provided on one side of the dust collection box 7, a second scraper 22 is provided on one side of the first slider 20, a limiting plate 23 is provided on one side of the first slider 20, an arc-shaped handle 24 is provided on the limiting plate 23, and a discharge port 25 is provided on one side of the dust collection box 7.

Then, remove the storage box 27 secured by bolts, and then remove the sealing arc strip 26. First, move the first slide bar 11 along the two sets of first slide grooves by using the handle 15. During the movement, the first scraper 14 will scrape off the debris on the inner wall of the protective cover 2, and the scraped debris will fall into the collection box 4 due to gravity. After the scraping is completed, push the first slide bar 11 and the first scraper 14 back to the original position by using the handle 15, and then proceed... When cleaning the dust collection box 7, the arc handle 24 drives the first slider 20 and the second scraper 22 to slide along the second arc groove 21. During the sliding, the second scraper 22 scrapes the remaining debris off the inner wall of the dust collection box 7 and discharges it through the discharge port 25. Then, push the arc handle 24, the first slider 20 and the second scraper 22 back to the original position. After that, reinstall the sealing arc strip 26 and the storage box 27, and then move the collection box 4 upward along the two sets of snap-fit ​​sliders 18 to remove it. Finally, clean the debris off the collection box 4.
