[0002] The transmission system of the cleaning machine configured in the cement packaging system is a driving roller connected to multiple driven rollers through a chain to complete the transportation. The driving rollers and the driven rollers are all designed with an integrated toothed disc and roller. Long-term operation and the cement packaging working environment lead to inadequate lubrication and rapid wear of the toothed disc. When the toothed disc is damaged, the rollers must be replaced as a whole. The replaced old rollers become waste. On the one hand, it is not conducive to reducing production costs. On the other hand, replacing new rollers requires shutdown, which affects production. It also requires the cooperation of multiple people to complete, which is time-consuming and labor-intensive. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a detachable toothed disc roller, which does not need to be disassembled when the toothed disc wears and affects the normal transmission work, and only needs to replace a new toothed disc to restore the normal work, which is convenient, fast, time-saving and labor-saving.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: a detachable toothed disc roller, including a roller shaft and a roller; a bushing is sleeved on one end of the roller shaft, the bushing is interference fit with the roller shaft, and the bushing is welded to the roller; the outer end of the bushing is detachably mounted with a toothed disc.

[0005] As a preferred technical solution, a limiting groove matching the inner end portion of the toothed disc is concavely arranged on the outer end surface of the bushing.

[0006] As a preferred technical solution, more than two threaded holes are distributed circumferentially on the groove surface of the limiting groove; connecting holes corresponding to the threaded holes are opened on the toothed disc, and the toothed disc and the bushing are fixedly connected by bolts.

[0007] As a preferred technical solution, more than two key slots are circumferentially distributed on the slot surface of the limiting slot; and a key block corresponding to the key slot is provided on the inner end surface of the toothed disc.

[0008] As a preferred technical solution, a sealing groove is concavely arranged on the outer end surface of the toothed disc, and a sealing pressure ring is arranged in the sealing groove.

[0009] As a preferred technical solution, more than two roller teeth are welded on the outer circumferential surface of the roller, and each of the roller teeth extends in the axial direction.

[0010] Due to the adoption of the above technical scheme, the utility model has at least the following beneficial effects: by installing a bushing on one end of the roller shaft, the bushing and the roller shaft are interference fit, the bushing is welded to the roller, and the outer end of the bushing is detachably installed with a toothed disc; in this way, when the toothed disc wears and affects the normal transmission operation, there is no need to stop the machine to disassemble the roller, but only need to replace a new toothed disc to resume normal operation, which can be completed by one person, which is convenient and fast, saves time and effort, and is conducive to cost saving.

[0019] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0020] like Figure 1 As shown, the detachable toothed disc roller comprises a roller shaft 1 and a roller 2; one end of the roller shaft 1 is sleeved with a bushing 3, the bushing 3 is interference fit with the roller shaft 1, and the bushing 3 is welded to the roller 2; the outer end of the bushing 3 is detachably mounted with a toothed disc 4.

[0021] refer to Figures 2 to 4 In this embodiment, a concave limit groove 31 is provided on the outer end surface of the bushing 3 to match the inner end of the toothed disc 4. Four threaded holes 32 are provided on the groove surface of the limit groove 31 along the circumferential direction; four key grooves 33 are also provided on the groove surface of the limit groove 31 along the circumferential direction; Figures 5 to 7 , the toothed disc 4 is provided with a connection hole 41 corresponding to the threaded hole 32, and the inner end surface of the toothed disc 4 is provided with a key block 42 corresponding to the keyway 33; when installing the toothed disc 4, the inner end of the toothed disc 4 is placed in the limit groove 31 of the outer end surface of the bushing 3, and after adjusting the connection hole 41 of the toothed disc to align with the threaded hole 32 of the bushing 3, the toothed disc 4 is fixedly connected to the bushing 3 by bolts, which is not only convenient for disassembly and assembly, but also can ensure that the toothed disc and the bushing have good coaxiality and positioning accuracy, which is conducive to extending the service life. Of course, the toothed disc 4 can also be detachably installed with the bushing 3 through other structures, which should all belong to the protection scope of the utility model.

[0022] refer to Figure 1 and Figure 7 A sealing groove 43 is concavely arranged on the outer end surface of the toothed disc 4, and a sealing pressure ring 5 is arranged in the sealing groove 43. The sealing pressure ring 5 can prevent impurities from entering as much as possible, thereby extending the service life of the toothed disc.

[0023] refer to Figure 1 A plurality of roller teeth 21 are welded on the outer circumferential surface of the roller 2, and each of the roller teeth 21 extends in the axial direction to improve the conveying stability.

[0024] When the toothed disc 4 is worn and affects the normal transmission work, there is no need to stop the machine to disassemble the roller. Instead, it is only necessary to remove the sealing pressure ring 5 and four bolts and replace the new toothed disc to resume normal operation. It can be completed by one person, which is convenient and fast, saving time and effort, and helping to save costs.

[0025] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
