Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] like Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a quick-change mechanism for glass fiber stub cutter heads, including a housing 1, a feed inlet 11 at one end of the housing 1, and a housing 12 fixedly connected to one side of the housing 1. A positioning cylinder 13 is provided on the inner side of the middle of the housing 1, and one end of the positioning cylinder 13 is fixedly connected to the output shaft of the housing 12. A discharge port 14 is fixedly connected to the lower end of the housing 1, and a collection box 15 is provided below the discharge port 14. A transmission assembly 2 is provided on the middle side of one side of the housing 12 inserted into the housing 1, and the transmission assembly 2 includes a set of transmission rods 21 fixedly connected to the output shaft of the housing 12. An electric telescopic rod 2 is fixedly connected to the end of the transmission rods 21 away from the housing 12. 2. The electric telescopic rod 22 is fixedly connected to a connecting plate 23 at the end away from the transmission rod 21. The connecting plate 23 is equipped with a locking component 3. The outer shell 1 is equipped with a protective component 4 at the end away from the machine box 12. The protective component 4 is equipped with a power component 5 at the end away from the outer shell 1. The power component 5 is equipped with a tool changing component 6 at one end. The tool changing component 6 is equipped with a positioning component 7 at the end away from the power component 5. When the tool cylinder 62 is replaced, the replacement operation can be completed automatically without opening the baffle 41 through the cooperation of the transmission component 2 and the locking component 3, thereby shortening the replacement time, effectively improving the replacement efficiency, and thus shortening the downtime and improving the processing efficiency.

[0024] like Figure 5As shown, the locking assembly 3 includes a locking plate 31 inserted inside the end of the connecting plate 23 away from the electric telescopic rod 22. A spring 32 is fixedly connected to one end of the locking plate 31 inserted into the connecting plate 23. The end of the spring 32 away from the locking plate 31 is fixedly connected to the connecting plate 23. When the electric telescopic rod 22 is started, it extends and pushes the connecting plate 23 to move, so that the connecting plate 23 fits with the corresponding positioning plate 71. During this process, the positioning plate 71 will squeeze the locking plate 31, so that the locking plate 31 is inserted into the connecting plate 23 and compresses the spring 32. Then, the machine box 12 is started, so that the output shaft of the machine box 12 drives the transmission rod 21 and the electric telescopic rod 22 to rotate. After the electric telescopic rod 22 rotates, it drives the connecting plate 23 to rotate. The rotation of the connecting plate 23 drives the locking plate 31 to rotate. When the locking plate 31 rotates to the positioning groove 72, the elastic potential energy of the spring 32 pushes the locking plate 31 to insert into the positioning groove 72, so that the connecting plate 23 and the positioning plate 71 are docked and locked.

[0025] like Figure 1 As shown, the protective component 4 includes a baffle 41 attached to the outer side of the outer shell 1 away from the chassis 12, and fastening bolts 42 are threaded on both ends of the baffle 41. The fastening bolts 42 are threaded on the outer shell 1 at the end near the outer shell 1. The fastening bolts 42 are unscrewed, and then the baffle 41 is removed, which drives the turntable 61 and the knife cylinder 62 to pull out the outer shell 1 for replacement.

[0026] like Figure 3 As shown, the power assembly 5 includes a protective cover 51 fixedly connected to the side of the baffle 41 away from the outer casing 1, and a motor 52 is fixedly connected inside the lower end of the protective cover 51. The output shaft of the motor 52 is fixedly connected to a first gear 53, and the upper end of the first gear 53 is meshed with a second gear 54. The middle end of the second gear 54 is rotatably connected to the baffle 41. After the motor 52 is started, the output shaft drives the first gear 53 to rotate. After the first gear 53 rotates, it drives the second gear 54 to rotate through the meshing of the gear with the second gear 54. After the second gear 54 rotates, it synchronously drives the turntable 61 and the cutter barrel 62 to rotate.

[0027] like Figure 3 As shown, the tool changing assembly 6 includes a turntable 61 fixedly connected to the second gear 54 near the outer casing 1 through the baffle 41, and a tool cylinder 62 fixedly connected to the turntable 61 away from the second gear 54.

[0028] like Figure 4 As shown, four sets of cutter barrels 62 are arranged in a circular array on the turntable 61.

[0029] like Figure 4As shown, the positioning assembly 7 includes a positioning plate 71 fixedly connected to the end of the cutter barrel 62 away from the turntable 61, and a positioning groove 72 is provided at the end of the positioning plate 71 away from the cutter barrel 62. When the clamping plate 31 rotates to the positioning groove 72, the elastic potential energy of the spring 32 pushes the clamping plate 31 to insert into the positioning groove 72, so that the connecting plate 23 docks and locks with the positioning plate 71, thereby enabling the connecting plate 23 to drive the corresponding cutter barrel 62 to rotate and complete the tool change.

[0030] Working principle: When the tool barrel 62 needs to be replaced, first close the machine housing 12, then start the electric telescopic rod 22 with the support of the transmission rod 21. After the electric telescopic rod 22 is started, the output shaft retracts, driving the connecting plate 23 to move, thereby allowing the connecting plate 23 to pull the clamping plate 31 out of the positioning groove 72, separating the connecting plate 23 from the positioning plate 71. Then, the motor 52 is started with the support of the baffle 41. After the motor 52 is started, the output shaft drives the first gear 53 to rotate. After the first gear 53 rotates, it meshes with the second gear 54, driving the second gear 54 to rotate. After the second gear 54 rotates, it synchronously drives the turntable 61 and the tool barrel 62 to rotate. When the tool barrel 62 to be used rotates to be parallel with the connecting plate 23, the motor 52 is turned off, and then the electric telescopic rod 22 is started. When the electric telescopic rod 22 is started, it extends and pushes the connecting plate 23 to move, thereby allowing the connecting plate 23 to move out of the positioning groove 72. 23 is attached to the corresponding positioning plate 71. During this process, the positioning plate 71 will squeeze the clamping plate 31, so that the clamping plate 31 is inserted into the connecting plate 23 and the spring 32 is compressed. Then the machine box 12 is started, so that the output shaft of the machine box 12 drives the transmission rod 21 and the electric telescopic rod 22 to rotate. After the electric telescopic rod 22 rotates, it drives the connecting plate 23 to rotate. The rotation of the connecting plate 23 drives the clamping plate 31 to rotate. When the clamping plate 31 rotates to the positioning groove 72, the elastic potential energy of the spring 32 pushes the clamping plate 31 to insert into the positioning groove 72, so that the connecting plate 23 and the positioning plate 71 are docked and locked. The connecting plate 23 drives the corresponding tool cylinder 62 to rotate, and the tool change is completed. When multiple sets of tool cylinders 62 need to be disassembled and repaired later, the fastening bolts 42 can be unscrewed, and then the baffle 41 can be removed to pull out the outer shell 1 to replace the tool.

[0031] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
