[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In actual use, due to the different sizes and lengths of the rubber rollers, different sizes of grinding machines are required for grinding. However, the existing dust collection hood has a fixed size and cannot be adjusted. This results in poor sealing when it is placed on the grinding device, which leads to an insignificant dust removal effect of the dust collection device.

[0021] In view of this, the present invention provides a dust removal device for fine grinding of rubber rollers, which solves the problem that in actual use, due to the different sizes and lengths of rubber rollers, different sizes of grinding machines are required for grinding. However, the existing dust collection hood has a fixed size and cannot be adjusted, resulting in poor sealing effect when it is placed on the grinding device, which leads to the dust removal effect of the dust collection device being insignificant.

[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0023] Example 1: By Figure 1-4 It is known that a dust removal device for fine grinding of rubber rollers includes a protective cover 1, an adjusting plate 11 installed on one side of the inner wall of the protective cover 1, and an adjusting device 2, a fixing device 3, and a dust collection device 4. The adjusting device 2 is installed on the outer wall of the adjusting plate 11; the fixing device 3 is installed on the side of the adjusting plate 11 away from the protective cover 1; and the dust collection device 4 is installed on the top of the protective cover 1. The adjusting device 2 adjusts the position of the adjusting plate 11, the fixing device 3 fixes the protective cover 1, and the dust collection device 4 absorbs the dust inside the protective cover 1.

[0024] In the specific implementation process, it is worth noting that the size of the protective cover 1 is adjusted by using the adjusting plate 11, so that the dust removal device can remove dust better and avoid the problem of insignificant dust removal effect. The fixing device 3 will install the protective cover 1 on the grinding device, so that the dust removal device is more stable when placed. The dust suction device 4 will suck out the dust inside the protective cover 1.

[0025] Furthermore, the adjusting device 2 includes a threaded rod 21, a fixed housing 22, a first gear 23, a second gear 24, and a drive rod 25. The threaded rod 21 is rotatably connected to the inner wall of the protective cover 1 via a sealed bearing, and its outer wall is threadedly connected to the inner wall of the adjusting plate 11. The fixed housing 22 is fixedly connected to the top of the inner wall of the protective cover 1, and its inner wall is rotatably connected to the outer wall of the threaded rod 21 on the side away from the protective cover 1 via a sealed bearing. The first gear 23 is fixedly connected to one end of the threaded rod 21 extending into the fixed housing 22. The second gear 24 is meshed with the outer wall of the first gear 23. The drive rod 25 is fixedly connected to the top of the second gear 24 and passes through the top of the protective cover 1 via a sealed bearing. Through the cooperation of the threaded rod 21 and the fixed housing 22, the drive rod 25 drives the adjusting plate 11 to move, and the first gear 23 drives the second gear 24 to rotate.

[0026] In the specific implementation process, it is worth noting that both the first gear 23 and the second gear 24 are bevel gears. When the second gear 24 rotates, it can drive the second gear 24 to rotate. The outer wall of the threaded rod 21 is provided with threads, and the threaded rod 21 is threadedly connected to the inner wall of the adjusting plate 11, so that the position of the adjusting plate 11 can be adjusted.

[0027] Furthermore, a clamping plate 13 is fixedly connected to the lower outer wall of the protective cover 1 on the side away from the adjusting plate 11. The fixing device 3 includes a clamping plate 31, a sleeve 32, a sliding rod 33, and a bolt 34. The clamping plate 31 is located on the lower outer wall of the adjusting plate 11 on the side away from the protective cover 1. The sleeve 32 is fixedly connected to the top of the clamping plate 31. The sliding rod 33 is inserted into the inner wall of the sleeve 32 and fixedly connected to the outer wall of the adjusting plate 11. The bolt 34 is threadedly connected to the inner wall of the sleeve 32, and one end extending into the inside of the sleeve 32 abuts against the top of the sliding rod 33. The clamping plate 31 is fixed by the cooperation of the sleeve 32 and the sliding rod 33, and the bolt 34 is fixed to the sleeve 32.

[0028] In the specific implementation process, it is worth noting that the length of the slide bar 33 is sufficient to allow the adjustment plate 11 to move the maximum distance. When the adjustment plate 11 moves a certain distance into the protective cover 1, the sleeve 32 moves outside the slide bar 33, which allows the clamping plate 31 to press against the outer wall of the grinding device. After the adjustment is completed, the bolt 34 is rotated to press against the top of the slide bar 33, thus fixing the position of the clamping plate 31. This ensures that the dust removal device is stable during operation.

[0029] Specifically, when using this dust removal device for fine grinding of rubber rollers, when removing dust from the grinding machine, the drive rod 25 drives the second gear 24 to rotate, and through the meshing of the second gear 24 with the first gear 23, the threaded rod 21 is driven to rotate, causing the adjusting plate 11 to move inside the protective cover 1, thereby reducing the space inside the protective cover 1. In this way, the protective cover 1 can correspond to the size of the grinding device, and the sliding sleeve 32 adjusts the position of the clamping plate 31, pressing the clamping plate 31 against the outer wall of the grinding device. After pressing, the bolt 34 is rotated so that the bottom of the bolt 34 presses against the top of the sliding rod 33, thus fixing the position of the clamping plate 31 and making the dust removal device stable during operation.

[0030] Example 2: From Figure 1-4It can be seen that the dust collection device 4 includes a connecting pipe 41, a blower 42, a dust collection box 43, a filter screen 44, and an exhaust pipe 45. The connecting pipe 41 is connected to the top of the protective cover 1; the input end of the blower 42 is connected to the end of the connecting pipe 41 away from the protective cover 1; the dust collection box 43 is fixedly connected to the outer wall of the blower 42 and connected to the output end of the blower 42; several filters 44 are provided, all inserted into the inner wall of the dust collection box 43; the exhaust pipe 45 is connected to the outer wall of the dust collection box 43; wherein, through the cooperation of the connecting pipe 41 and the blower 42, the dust in the protective cover 1 enters the dust collection box 43, and the filters 44 filter the dust and discharge it through the exhaust pipe 45. The model of the blower 42 is not limited, as long as it meets the actual use conditions.

[0031] In the specific implementation process, it is worth noting that the inner wall of the connecting pipe 41 is relatively smooth, which can prevent dust from adhering to the inner wall of the connecting pipe 41. Moreover, under the action of the blower 42, the dust is transported to the inside of the dust collection box 43. Furthermore, several filters 44 are installed inside the dust collection box 43, and the filters 44 will remove dust from the gas to prevent dust from flying around.

[0032] Furthermore, a limiting post 12 is inserted into the inner wall of the adjusting plate 11, and one end of the limiting post 12 is fixedly connected to the inner wall of the protective cover 1.

[0033] In the specific implementation process, it is worth noting that there are two limit posts 12, which are set on the front and back of the inner wall of the protective cover 1. This makes the adjustment plate 11 more stable when it moves and avoids instability of the adjustment plate 11 when it moves.

[0034] Furthermore, a flexible hose 14 is sleeved on the outer wall of the threaded rod 21, and the two ends of the flexible hose 14 are fixedly connected to the inner wall of the protective cover 1 and the surface of the adjusting plate 11, respectively.

[0035] In the specific implementation process, it is worth noting that the threaded rod 21 inside the protective cover 1 is wrapped with a hose 14 to prevent debris from adhering to its outer wall and affecting its normal operation.

[0036] Specifically, based on the above embodiments, when adjusting the adjusting plate 11, the limiting post 12 can ensure that the adjusting plate 11 is stable when moving, and press the clamping plate 13 against the outer wall of the grinding device, while the clamping plate 31 will clamp on the other side of the grinding device. In this way, the dust removal device can be fixed as a whole on the grinding device. Moreover, when the protective cover 1 is installed, there will be a gap between it and the grinding device. This allows the gas inside the protective cover 1 to circulate when the blower 42 is working, preventing the dust inside the protective cover 1 from not being discharged under the action of suction.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
