DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5 The utility model provides a technical solution: it includes a support frame 1, a horizontal shaft 2 is rotatably provided on the inner side of the support frame 1, a plurality of crosses 3 are connected to the middle end of the horizontal shaft 2, and the outer side of the cross 3 is connected to the same group of cylinders 4, which evenly support the inner wall of the cylinder 4 to ensure stability in use. One end of the horizontal shaft 2 passes through the support frame 1 and is connected to a reduction motor 5, which is fixedly installed on one side of the support frame 1. A plurality of displacement units 6 are connected to the surface of the cylinder 4.

[0024] Reference Figure 3The displacement unit 6 includes two groups of positioning base plates 61, and a guide rod 62 and a screw rod 64 are connected between the two groups of positioning base plates 61. A movable base plate 63 is slidably provided at one end of the guide rod 62, and the screw rod 64 is slidably connected to the movable base plate 63. When the servo motor 8 drives the active wheel 9 to rotate, the driven wheel 65 at one end of the screw rod 64 is driven to rotate through the transmission belt 10, thereby driving the screw rod 64 to rotate, thereby causing the movable base plate 63 to move. The running direction is controlled by the forward and reverse rotation of the servo motor 8. Multiple connections are provided on one side of the inner ring of the cylinder 4. The mounting frame 7 is a group, and the top of the mounting frame 7 is connected to a servo motor 8. The output end of the servo motor 8 is connected to a driving wheel 9. A transmission belt 10 is sleeved and connected between the driving wheel 9 and the driven wheel 65 to ensure the transmission effect, so that each group of displacement units 6 can be operated independently. The tops of the two positioning base plates 61 and the movable base plate 63 are connected to a clamping mechanism 12. The clamping mechanism 12 clamps the pipe fittings and automatically loads the pipes as the movable base plate 63 moves. The top of the support frame 1 is connected to a material guide box 13 and a cutting unit 14.

[0025] A distance sensor 11 is connected to the side of the positioning seat plate 61 close to the movable seat plate 63. When the movable seat plate 63 moves, the distance sensor 11 will detect the travel distance of the movable seat plate 63, so as to detect the feeding length of the processed pipe fittings, thereby controlling the cutting size.

[0026] like Figure 2 As shown, the clamping mechanism 12 includes two sets of clamping plates 121, which are curved to facilitate clamping square tubes and round tubes. A telescopic rod 122 is rotatably set on the side of the clamping plates 121 away from each other, and a transmission roller 123 is rotatably set on one side of the two surfaces of the clamping plates 121. A vertical plate 124 is connected to the side of the clamping plates 121 away from each other. The vertical plate 124 is located on both sides of the transmission roller 123, and a cylinder 125 is connected to one side of the vertical plate 124. The output end of the cylinder 125 passes through the vertical plate 124 and is connected to a positioning plate 126. The cylinder 125 extends to push the positioning plate 126 to move, thereby clamping and fixing the transmission roller 123 so that it will not rotate, which is convenient for fixing the pipe fitting when the clamping mechanism 12 is clamped. When the clamping mechanism 12 on the movable seat plate 63 clamps the pipe fitting and moves, the transmission roller 123 in the clamping mechanism 12 on the positioning seat plate 61 is loosened by the positioning plate 126, which is convenient for the movement and loading of the pipe fitting.

[0027] The outer surface of the transmission roller 123 is sleeved with a rubber sleeve, and a limiting groove is provided on the surface of the rubber sleeve. On the one hand, it can ensure the protection of the surface of the pipe during clamping, and on the other hand, it prevents sliding and ensures the fixing effect. The positioning plate 126 is provided with limiting teeth on the side close to the rubber sleeve to ensure the positioning effect of the transmission roller 123. The other end of the telescopic rod 122 is rotatably set at the top of the positioning seat plate 61. The telescopic rod 122 is retracted or extended to control the opening and closing of the clamping plate 121, which is convenient for the fixed clamping of the pipe.

[0028] like Figure 4 As shown, the cutting unit 14 includes a stabilizing frame 141, and a saw blade 142 is rotatably arranged between the stabilizing frame 141. A circular shaft is connected to one side of the saw blade 142, and one end of the circular shaft passes through the stabilizing frame 141 and is connected to a gearbox 143. A driving motor 144 is connected to the other side of the gearbox 143. The driving motor 144 drives the gearbox 143, and the gearbox 143 drives the saw blade 142 to rotate through the circular shaft to cut the pipe. The saw blade 142 is located on one side of the cylinder 4 and is close to the clamping mechanism 12. One side of the driving motor 144 extends into the material guide box 13. The bottom end of the driving motor 144 is connected to a supporting base, and the supporting base is fixedly arranged at the bottom end of the inner wall of the material guide box 13, which can effectively prevent the cut pipe from hitting the driving motor 144 when it falls and causing damage. A heat dissipation hole is opened on one side of the material guide box 13 to ensure the basic heat dissipation effect of the driving motor 144.

[0029] The implementation principle of the sprayer with a medicine mixing function in the embodiment of the present application is as follows: the pipe is clamped between the clamping plates 121, the telescopic rod 122 extends to lift the clamping plate 121 to rotate, thereby clamping the pipe, the reduction motor 5 drives the horizontal shaft 2 to rotate, so that the cylinder 4 rotates with the pipe, and is cut when passing through the rotating saw blade 142. The cut pipe will slide down along the top of the guide box 13, and the displacement unit 6 and the clamping mechanism 12 have multiple groups that can cut continuously. After the cutting is completed, the servo motor 8 starts to drive the driven wheel 65 to rotate through the transmission belt 10, thereby driving the movable seat plate 63 to move, and the movable seat plate 63 is located on the movable seat plate 63. The square clamping mechanism 12 clamps the pipe and moves so that the end of the pipe exceeds the cylinder 4. The moving distance is detected by the distance sensor 11, and the length to be cut is determined. When the movable seat plate 63 moves, the positioning plate 126 in the clamping mechanism 12 on the positioning seat plate 61 releases the transmission roller 123 to facilitate the movement of the pipe. After moving to the expected position, the positioning plate 126 clamps the transmission roller 123 to fix the pipe. When the movable seat plate 63 is reset, the transmission roller 123 above it is also released and fixed after reset, thereby completing automatic feeding. The extended pipe continues to be cut by the saw blade 142 as the cylinder 4 rotates.
