This utility model provides a structure for a scraper roller assembly, which includes a roller 1, an adjusting part 2, and a wrench part 3; wherein, the adjusting part 2 includes a worm gear 21, a worm 22, a bearing 23, a bearing seat 231, a seal 232, a bearing seat cover 233, an oil-free bushing 24, a horizontal bearing 25, a drive shaft 26, a digital display 27, a fastener 28, a mechanism mounting base 4, a protective cover 41, a scale 42, and an adjusting bolt assembly 43.

[0022] The mechanism mounting base 4 is provided with a bearing housing 231 and a drive shaft 26. The bearing housing 231 has a bearing groove (not shown) inside to accommodate the bearing 23. The bearing housing 231 also includes a bearing housing cover 233, which covers the bearing housing 231 and the bearing 23, and a seal 232 is provided on the side of the bearing housing 231 to seal it. The roller 1 passes through the mechanism mounting base 4, the bearing housing 231 and the bearing 23, and the worm gear 21 is sleeved on one end of the roller 1. In other words, starting from the worm gear 21 and extending along the direction of the roller 1, the sequence is worm gear 21, bearing housing cover 231, bearing 23 and mechanism mounting base 4. A protective cover 41 covers the worm gear 21, bearing 23, bearing housing 231 and bearing cover 232 to prevent the aforementioned components from being damaged by collision. In addition, the protective cover 41 has an opening (not shown) through which the worm gear 21 and worm 22 can mesh with each other.

[0023] A drive shaft 26 passes through a worm gear 22, extending in the same direction as the worm gear 22. The drive shaft 26 includes a counting end (not shown) and a fixed end (not shown). The worm gear 22 is positioned between the counting end and the fixed end. Oil-free bushings 24 are respectively arranged around both sides of the worm gear 22 to prevent slippage. Horizontal bearings 25 are respectively arranged on the side of the oil-free bushings 24 away from the worm gear 22 to support the drive shaft 26. A digital display 27 is located at the counting end of the drive shaft 26, connected to the worm gear 22, and displays the rotation angle of the roller 1. This display is based on the gear ratio to calculate the rotation angle of the roller 1 connected to the worm gear 21 after one revolution, providing a visually representable rotation angle value for the scraper roller assembly. A fastener 28 is located at the fixed end to secure the drive shaft 26 and prevent it from shifting. The fastener 28 can be secured using bolts.

[0024] The wrench unit 3 includes a wrench body 31, a ratchet 32, two pawl assemblies 33, and a retaining spring 36. The wrench body 31 includes a handle 311 and a receiving groove 312. The pawl assembly includes pawls 34 and elastic members 35. The wrench body 31 is selectively detachable and tractably connected to the adjustment unit 2. More specifically, the wrench body 31 is partially tractively connected to the drive shaft 26 via the receiving groove 312. The receiving groove 312 is located at one end of the handle 311, and the ratchet 32, pawl assemblies 33, and retaining spring 36 are all located within the receiving groove 312. The ratchet 32 ​​is located at the end of the receiving groove 312 away from the handle 311, the two pawl assemblies 33 are located at the end of the receiving groove 312 adjacent to the handle 311, and the retaining spring 36 is located at the other end of the receiving groove 311. Between the pawl assemblies 33, the ratchet 32 ​​and the two pawl assemblies 33 together enclose an area. The retaining spring 36 is located within this area, and the elastic element 35 is connected to the inner wall of the receiving groove 312 and is disposed on the side of the pawl 34 away from the retaining spring 36. In addition, the wrench part 3 also has a toggle switch (not shown). When the toggle switch is toggled, the retaining spring 36 will switch from the pawl assembly 33 that originally stopped the ratchet 32 ​​to another pawl assembly 33. The pawl 34 in the original pawl assembly 33 will be removed from the state of stopping the ratchet 32 ​​due to the compression of the connected elastic element 35. The other pawl assembly 33 will extend because the spring 35 is no longer under force, and push out the pawl 34 to stop the ratchet 32. The rotation direction of the drive shaft 26 can be changed by the aforementioned mechanism. This is one embodiment of the present invention.

[0025] Example 2

[0026] The scraper roller assembly provided in this embodiment has the same structure and operating principle as that in Embodiment 1. However, the difference between this embodiment and Embodiment 1 is that an adjustment part and a wrench part with the same structure are provided at the other end of the roller, allowing the user to control the roller at both ends.

[0027] Example 3

[0028] The scraper roller assembly structure provided in this embodiment is largely the same as that in Embodiment 1, but there are some adjustments to the structure of the wrench part 3. The number of pawls 33 is adjusted to a single one, and it includes a pawl 34, a push rod 37 and an elastic element 35. The pawl 34 is crescent-shaped or rocker-shaped. The push rod 37 passes through the connection between the receiving groove 312 and the handle 311, and the push rod 37 is located at one end adjacent to the receiving groove 312. The elastic element 35 is located between the push rod 37 and the handle 311. The pawl 34 is located between the push rod 37 and the ratchet 32. The snap ring 36 is stacked on one side of the ratchet 32 ​​away from the bottom of the receiving groove 312. In addition, the wrench part 3 also has a toggle switch (not shown). When the toggle switch is toggled, the push rod 37 will change its angle with the toggle switch. The elastic element 35 will press the push rod 37 against the pawl 34 to ensure that it engages with the ratchet 32 ​​due to its elastic force. The direction of the ratchet 32 ​​can be changed by switching through the toggle switch.

[0029] Example 4

[0030] The scraper roller assembly provided in this embodiment has the same composition and operating principle as that in embodiment 3. However, the difference between this embodiment and the embodiment is that an adjustment part and a wrench part with the same structure are provided at the other end of the roller, allowing the user to control the roller at both ends.

[0031] The scraper roller assembly structure provided by this utility model is easy to operate and saves working space because it replaces the turntable with a wrench. The gear ratio between the worm gear and the worm reduces the effort required for rotation, and the rotation angle of the roller connected to the worm gear can be calculated by the gear ratio. Therefore, the digital display can convert the number of rotations of the transmission shaft through the gear ratio, and thus the rotation angle of the roller can be seen by the displayed value, making the scraper roller assembly structure have a visual rotation angle value. In addition, the bolts in the adjusting bolt assembly can move the entire mechanism left and right, and the amount of movement and position can be determined by the scale. Through the above combination, the operating accuracy and convenience of the scraper roller assembly structure can be greatly improved.

[0032] The above content involving common knowledge will not be described in detail, as those skilled in the art will understand.

[0033] The embodiments described above are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
