Description

Technical Field

[0001] The utility model belongs to the technical field of logging machines, and particularly relates to a feeding mechanism driven by a spline sleeve. Background Technique

[0002] In the wood processing industry, as a core device, the performance and stability of a logging machine play a crucial role in production efficiency and cost control. As one of the core components, the feeding mechanism has extremely high operating intensity. Therefore, the spline drive is often adopted for the transmission structure of the feeding mechanism, which can effectively bear the load. However, in the existing spline drive mechanism of the feeding mechanism of a logging machine, the splines are usually processed deep inside the feeding roller, and it is difficult for heat treatment equipment to reach these areas, increasing the complexity and cost of processing. Moreover, it is difficult for the heat treatment process to fully penetrate into the deep parts of the splines. Since heat treatment requires uniform heating and cooling, it is difficult for the deep splines to reach the required temperature and cooling rate, resulting in insufficient hardness and strength of the splines, making it difficult to bear the high-intensity operating load during the logging process, with a high failure rate, easy deformation and wear of the splines. And the existing splines are usually fixedly processed in the feeding roller. After the splines are worn and deformed, only the entire feeding roller can be replaced, greatly increasing the use cost. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a feeding mechanism driven by a spline sleeve to solve the technical problems in the above-mentioned background technique that the splines of the feeding roller in the existing technology have insufficient strength and hardness, need to be replaced as a whole when there is a failure, and have a high use cost, and can improve the service life of the splines of the feeding roller and reduce the use cost.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A feeding mechanism driven by a spline sleeve includes a feeding roller and a spline sleeve. The feeding roller is horizontally arranged left and right, and through channels are provided at both its left and right ends, and counterbores are opened on the outer sides of both ends of the channels; the spline sleeve includes a shaft sleeve and a transmission disk; spline teeth are provided inside the shaft sleeve; the transmission disk is a vertically arranged circular ring structure, and its inner ring is sleeved on the outer side wall of one end of the shaft sleeve; there are two spline sleeves, which are arranged opposite to each other. One end of the shaft sleeve of the two spline sleeves enters the channel of the feeding roller, and the other end is detachably connected to the counterbore through the transmission disk.

[0006] Further, connection holes are circumferentially and spacedly opened in the counterbore; fixing holes are circumferentially opened in the transmission disk, and the fixing holes are connected to the connection holes through bolts to connect the transmission disk to the counterbore.

[0007] Further, an opening communicating with the channel is opened on the feeding roller; an oil nozzle is provided on the opening.

[0008] Furthermore, a plug is provided on the nozzle.

[0009] Furthermore, it further includes a motor; there are two motors, and spline grooves are provided on the output shafts of the two motors. The output shafts of the two motors respectively pass through the drive disks of the two spline sleeves and enter the shaft sleeve, and mesh with the spline teeth inside the shaft sleeve.

[0010] The working principle and process of the present utility model are as follows:

[0011] Insert the shaft sleeves of the two spline sleeves into the channels at both ends of the feeding roller in a relative form. One end of the spline sleeve is aligned with the counterbore of the feeding roller through the drive disk, and then use bolts to fix the drive disk in the counterbore, so that the spline sleeve is firmly connected to the feeding roller. Pass the output shafts of the two motors through the drive disks of the two spline sleeves respectively and enter the shaft sleeve, so that the spline grooves on the output shafts of the motors mesh with the spline teeth inside the shaft sleeve to complete the installation. After the motor is started, the output shaft meshes with the spline teeth through the spline groove, transmits the power to the spline sleeve, and the spline sleeve transmits the power to the feeding roller through the drive disk, so that the feeding roller rotates. When the feeding roller rotates, the wood is fed.

[0012] The beneficial effects of the present utility model compared with the prior art are as follows:

[0013] 1. By changing the original method of fixing and processing the spline with the feeding roller to an independent spline sleeve and the feeding roller, and respectively assembling the drive disk in the two spline sleeves with the counterbore of the feeding roller through bolts, the independent spline sleeve is more convenient for heat treatment, thus greatly improving the hardness of the spline, extending the service life, and it is easy to replace the spline sleeve after wear, without replacing the entire feeding roller, reducing the use cost.

[0014] 2. By providing a nozzle on the feeding roller, it can directly lubricate the spline in the spline sleeve, reduce the wear caused by friction, and thus extend the service life of the spline. Description of the Drawings

[0019] To make the purpose, technical solution and advantages of the present utility model clearer and more understandable, the following preferred embodiments are cited with reference to the accompanying drawings to further elaborate on the present utility model in detail. However, it should be noted that many details listed in the specification are only for enabling the reader to have a thorough understanding of one or more aspects of the present utility model, and these aspects of the present utility model can be implemented even without these specific details.

[0020] A feeding mechanism driven by a spline sleeve, including a feeding roller 1 and a spline sleeve 2. The feeding roller 1 is horizontally arranged left and right, and through channels 11 are provided at both its left and right ends. Counterbores 12 are opened outside both ends of the channels 11; the spline sleeve 2 includes a shaft sleeve 21 and a transmission disc 22; spline teeth 212 are provided inside the shaft sleeve 21; the transmission disc 22 is a vertically arranged circular ring structure, and its inner ring is sleeved on the outer side wall of one end of the shaft sleeve 21; there are two spline sleeves 2, and the two spline sleeves 2 are arranged oppositely. One end of the shaft sleeve 21 of the two spline sleeves 2 enters the channel 11 of the feeding roller 1, and the other end is detachably connected to the counterbore 12 through the transmission disc 22. By providing two independent spline sleeves 2, it is easier to perform heat treatment on the splines during processing, thereby improving the hardness and strength of the splines; by detachably connecting the two spline sleeves 2 to the feeding roller 1, it is not necessary to replace the entire feeding roller 1 after the splines are worn.

[0021] Connecting holes 121 are circumferentially spaced apart in the counterbore 12; fixing holes 221 are circumferentially opened in the transmission disc 22, and the fixing holes 221 are connected to the connecting holes 121 through bolts 3 to connect the transmission disc 22 to the counterbore 12. Connecting the transmission disc 22 to the counterbore 12 of the feeding roller 1 through bolts 3 is convenient for disassembly and assembly, and thus convenient for maintenance or replacement.

[0022] An opening 13 communicating with the channel 11 is provided on the feeding roller 1; an oil nozzle 14 is provided on the opening 13. Lubricating oil is sprayed on the spline sleeve 2 through the oil nozzle 14, thereby reducing the wear of the spline teeth 212 inside the spline sleeve 2 and increasing the service life of the spline sleeve 2.

[0023] A plug 15 is provided on the oil nozzle 14. When oil spraying is required, the plug 15 is taken out, and the oil nozzle 14 is blocked by the plug 15 during operation to prevent impurities from entering the oil nozzle 14, thereby preventing impurities from entering the spline sleeve 2 along with the lubricating oil when the oil nozzle 14 sprays oil, increasing the wear of the spline teeth 212, and further increasing the service life of the spline sleeve 2.

[0024] It further includes a motor 4; there are two motors 4, and spline grooves are provided on the output shafts of the two motors 4. The output shafts of the two motors 4 respectively pass through the drive discs 22 of the two spline sleeves 2 and enter the sleeve 21, and are engaged with the spline teeth 212 inside the sleeve 21. The spline sleeve 2 is driven to rotate by the motor 4, so that the feeding roller 1 rotates.

[0025] The working mode of the present utility model is as follows:

[0026] The sleeves 21 of the two spline sleeves 2 are respectively inserted into the channels 11 at both ends of the feeding roller 1 in a relative form. One end of the spline sleeve 2 is aligned with the counterbore 12 of the feeding roller 1 through the drive disc 22, and then the drive disc 22 is fixed to the counterbore 12 by using the bolt 3, so that the spline sleeve 2 is firmly connected to the feeding roller 1. The output shafts of the two motors 4 respectively pass through the drive discs 22 of the two spline sleeves 2 and enter the sleeve 21, so that the spline grooves on the output shafts of the motors 4 are engaged with the spline teeth 212 inside the sleeve 21, and the installation is completed. After the motor 4 is started, the output shaft is engaged with the spline teeth 212 through the spline groove, and the power is transmitted to the spline sleeve 2. The spline sleeve 2 transmits the power to the feeding roller 1 through the drive disc 22, so that the feeding roller 1 rotates. When the feeding roller 1 rotates, the wood is fed.

[0027] The above is only the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
