Description

Technical Field

[0001] This utility model relates to the field of cigarette machinery and equipment technology, and more specifically, to a motor pulley disassembly device for cigarette factories. Background Technology

[0002] In the tobacco processing and transportation process, belt drives are often used. There are generally two ways to install belt pulleys on motors: one is to connect the motor shaft and the belt pulley by pin positioning, and the other is to connect the motor shaft and the belt pulley by interference fit. In the interference fit, the belt pulley is installed without a pin. Because the belt pulley without a pin is installed with an interference fit to the motor shaft, it is difficult to disassemble.

[0003] In the current process of disassembling pinless pulleys for motors, the pinless pulley is usually knocked off the motor shaft directly with a hammer. This method can easily damage the pinless pulley and makes it difficult to remove.

[0004] Therefore, how to provide a motor pulley disassembly device for cigarette factories has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0027] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a motor pulley disassembly device for a cigarette factory, wherein the end of the pulley 6 has multiple fixing holes 61 and grooves 62;

[0028] The disassembly device for the motor 4 pulley 6 includes a fixing component 1 and a disassembly component 2;

[0029] The fixing component 1 includes a fixing plate 11, fixing bolts 12 and connecting holes 13. The connecting holes 13 are provided on the fixing plate 11 and are evenly spaced along the circumference of the fixing plate 11. The fixing bolts 12 pass through the connecting holes 13 and are connected to the fixing holes 61.

[0030] The disassembly assembly 2 includes a lead screw 21, a lead hole 22, and a fixing part. The lead hole 22 is located at the center of the fixing plate 11. The lead screw 21 is connected to the lead hole 22, and the fixing part is located in the groove 62 of the pulley 6. The first end of the lead screw 21 is connected to the fixing part.

[0031] This invention features a connecting hole 13 evenly spaced along the circumference of a fixing plate 11, with fixing bolts 12 passing through the connecting hole 13 and connecting to the fixing hole 61. A threaded hole 22 is positioned at the center of the fixing plate 11, with a lead screw 21 connected to the threaded hole 22. The fixing part is located within the groove 62 of the pulley 6, and the first end of the lead screw 21 is connected to the fixing part. During disassembly, the operator first connects the fixing plate 11 to the pulley 6 using the fixing bolts 12 passing through the connecting hole 13 and connecting to the fixing hole 61. Then, the lead screw 21 is connected to the threaded hole 22 and the fixing part. The operator then uses the machine to pull the pulley 6 off the shaft 5 of the motor 4, thus completing the disassembly of the pulley 6. This invention provides a simpler structure for disassembling motor pulleys in cigarette factories, making it convenient to use, avoiding damage to the pulley 6 from hammering, and increasing the ease of disassembly.

[0032] In one embodiment of the motor pulley disassembly device for cigarette factories of this utility model, such as... Figure 1 and Figure 2 As shown, there are three connecting holes 13, and the connecting holes 13 are oblong holes.

[0033] Specifically, the angle formed between two adjacent connecting holes 13 is 120 degrees, and because the connecting holes 13 are designed as waist-shaped holes, the fixing plate 11 can be matched with different types of pulleys 6, which improves the practicality of the motor pulley disassembly device used in cigarette factories.

[0034] In one embodiment of the motor pulley disassembly device for cigarette factories of this utility model, such as... Figure 1 and Figure 2 As shown, a fixing ring 14 is provided at the center of the fixing plate 11. The fixing ring 14 is connected to the threaded hole 22, and the screw rod 21 is threadedly connected to the fixing ring 14 and the threaded hole 22.

[0035] This invention increases the connection area of ​​the screw rod 21 by connecting the fixing ring 14 to the threaded hole 22 and threading the screw rod 21 to the fixing ring 14 and the threaded hole 22, thereby effectively improving the stability of the disassembly process.

[0036] In one embodiment of the motor pulley disassembly device for cigarette factories of this utility model, such as... Figure 1 and Figure 2 As shown, the motor pulley disassembly device for cigarette factories also includes a connecting block 3, which is connected to the second end of the lead screw 21, and the cross-section of the connecting block 3 is hexagonal.

[0037] This invention connects the connecting block 3 to the second end of the mounting rod, and makes the cross-section of the connecting block 3 a hexagonal structure, so that the operator can move the mounting rod by acting on the connecting block 3, thereby increasing the efficiency and convenience of disassembly.

[0038] In one embodiment of the motor pulley disassembly device for cigarette factories of this utility model, such as... Figure 1 and Figure 2 As shown, the fixing plate 11 is also provided with a waist-shaped opening 15, which is located between two adjacent connecting holes 13.

[0039] This invention provides a waist-shaped opening 15 between two adjacent connecting holes 13, thereby enabling the fixing plate 11 to be installed on pulleys 6 of different models when facing different models of pulleys 6.

[0040] In one embodiment of the motor pulley disassembly device for cigarette factories of this utility model, such as... Figure 1 and Figure 2 As shown, the fixing part includes a fixing sleeve 23, a connecting plate 24, a protrusion 25, a bearing 26, and an annular plate 27. The two ends of the connecting plate 24 are respectively connected to the first end of the fixing sleeve 23 and the annular plate 27. The second end of the fixing sleeve 23 is connected to the cigarette connecting hole 13. The first end of the lead screw 21 is connected to the fixing sleeve 23. The protrusion 25 is located at the center of the connecting plate 24, and the annular plate 27 is located on the outside of the protrusion 25. The bearing 26 is located on the protrusion 25.

[0041] Specifically, the fixed sleeve 23 is fixedly connected to the fixed plate 11, and the protrusion 25 is rolled on the connecting plate 24.

[0042] This invention connects the second end of the fixed sleeve 23 to the cigarette connecting hole 13, connects the first end of the lead screw 21 to the fixed sleeve 23, and sets the protrusion 25 at the center of the connecting plate 24. The annular plate 27 is located outside the protrusion 25, and the bearing 26 is set on the protrusion 25. When the fixed plate 11 is installed on the pulley 6, the protrusion 25 and the bearing 26 abut against the rotating shaft 5 of the motor 4. When the rotating shaft 5 rotates, it can drive the protrusion 25 to rotate, but will not drive the entire motor pulley disassembly device used in cigarette factories to rotate, effectively increasing stability.

[0043] In one embodiment of the motor pulley disassembly device for cigarette factories of this utility model, such as... Figure 1 and Figure 2 As shown, the fixing part also includes a limiting ring 28, which is sleeved on the protrusion 25 and abuts against the bearing 26.

[0044] This utility model provides a limiting ring 28 on the protrusion 25 and abuts against the bearing 26, thereby limiting the bearing 26 and ensuring the stability of the bearing 26 installation.

[0045] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
