Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The present invention will be further described below in conjunction with the embodiments.

[0022] Embodiment 1:

[0023] Reference Figure 1-4 , which is the first embodiment of the present invention, discloses a one-time two-piece automatic straw insertion machine, including a workbench 8 and a feeding mechanism 3 and a storage vibration plate installed on the workbench 8, the input end of the feeding mechanism 3 is connected with the output end of the storage vibration plate, a press pump 1 is arranged in the feeding mechanism 3, a screw rod 5 is rotatably arranged on the workbench 8, a straw clamping, insertion and cutting mechanism 4 threadedly mounted with the screw rod 5 is also installed on the workbench 8, a straw clamping, insertion and cutting mechanism 4 is installed with a straw 2 connected to the output end of the press pump 1, and symmetrically distributed pump head positioning and clamping structures 10 are installed on both sides of the feeding mechanism 3.

[0024] Embodiment 2:

[0025] Reference Figure 1-4, which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: the feeding mechanism 3 includes a feeding guide groove 11 installed on the workbench 8, and upper cylinders 12 and lower cylinders 17 are installed on both sides of the feeding guide groove 11, and pump head falling positioning baffles 14 are installed at the bottom of the two lower cylinders 17, and a pump head falling positioning baffle rod 13 is arranged on the top of the pump head falling positioning baffle 14, and a pump head falling positioning baffle rod 13 is arranged on the top of the pump head falling positioning baffle 14, and a pump head 16 is arranged on the top of the two pump head falling upper positioning baffles 15, and a feeding guide groove reinforcing partition plate 18 is installed at the lower notch of the feeding guide groove 11, and cylinder support seats 19 are installed at the connection between the upper cylinder 12 and the lower cylinder 17 and the outer wall of the feeding guide groove 11, and a baffle 20 is arranged in the feeding guide groove 11;

[0026] The pump 1 passes through the feeding mechanism 3 to the pump head positioning and clamping structure 10. The feeding mechanism 3 is connected to the storage vibration plate. The storage vibration plate pushes the disorderly placed products into the feeding mechanism 3 according to the standard direction of the pump 1. The feeding mechanism 3 is a double-material conveying, with 2 feeding troughs. Each time, 2 products fall into the pump head positioning and clamping structure 10. The pump head positioning and clamping structure 10 is bilaterally symmetrical, with each side responsible for a corresponding pump head, each of which is distributed with upper and lower cylinders;

[0027] like Figure 3 As shown, the air cylinder at the bottom moves, driving the installed pump head to fall down the lower positioning baffle 14 and the pump head falling positioning blocking rod 13 to block the bottommost pump 1, and the air cylinder at the top moves, driving the installed pump head to fall down the upper positioning baffle 15 and the pump head falling positioning blocking rod 13 to block the second to last pump and clamp the bottommost pump 1 together with the pump head falling upper positioning baffle 15 on the upper cylinder. At this time, the straw clamping, inserting and cutting mechanism 4 is driven by the servo motor 7 through the screw rod 5 and the pump head installed in the straw clamping, inserting and cutting mechanism. The nut at the bottom of the mechanism 4 acts to move forward to the preset position, insert the suction tube 2 into the pump 1, and then the mechanism is reset to retreat and cut off the suction tube. After the cutting action is completed, the cylinder below the pump head positioning and clamping structure 10 first withdraws to allow the pump head 16 with the completed insertion to fall into the discharge chute and then resets to block the feeding guide groove of the feeding mechanism 3. At this time, the upper cylinder withdraws, and the blocked pump 1 falls into the pump head falling positioning baffle 14 and the pump head falling positioning blocking rod 13 of the lower cylinder. At this point, the insertion action of the second pump suction tube is repeated;

[0028] Figure 3The pump head positioning and clamping structure shown in FIG. (a) shows a state in which the pump head 16 is blocked by the pump head falling upper positioning baffle 15 and the pump head falling positioning blocking rod 13 driven by the upper cylinder 12; FIG. (b) shows a state in which the pump head 16 is blocked by the pump head falling upper positioning baffle 15 and the pump head falling positioning blocking rod 13 driven by the lower cylinder 17; FIG. (c) shows a state in which the pump head 16 is blocked and clamped by the pump head falling upper positioning baffle 15 and the pump head falling positioning blocking rod 13 driven by the upper and lower cylinders;

[0029] The upper and lower pump head positioning baffles move on the guide rails 9 provided on the cylinder support seat 19. The upper and lower positioning baffle rods are circular and also move through the guide holes provided on the cylinder support seat 19, which ensures the accuracy of the positioning baffle. Similarly, a baffle 20 is provided behind the feeding guide groove mechanism to prevent the pump head 16 from jumping out of the guide groove when the tube is inserted.

[0030] A screw support 6 is installed on the workbench 8, and one end of the screw 5 away from the servo motor 7 rotates and penetrates the screw support 6. A servo motor 7 for driving the screw 5 to rotate is fixedly installed on the workbench 8. Two rows of guide rails 9 are installed on the workbench 8. The straw clamping, inserting and cutting mechanism 4 includes a screw nut 25 threadedly sleeved on the screw 5, and a mounting mainboard 27 is installed on the screw nut 25. A front beam plate 26 is also installed on the top of the workbench 8. Two axially symmetrically distributed straw clamping cylinders 24 are installed on the top of the mounting mainboard 27. The output ends of the straw clamping cylinders 24 are both installed with straw clamping blocks 23. Two pipe cutting cylinders 22 are axially symmetrically arranged on the mounting mainboard 27, and the output ends of the two pipe cutting cylinders 22 are both installed with blade holders 21.

[0031] The workbench 8 is also provided with a screw support seat 28, and one end of the screw 5 passes through the screw support seat 6 and is rotatably mounted on the screw support seat 28. The screw support seat 28 is fixedly mounted with a rear beam plate 29 at one end away from the screw 5. The rear beam plate 29 is mounted on the workbench 8. A pipe cutting cylinder fixing block 30 is installed between the pipe cutting cylinder 22 and the mounting main board 27.

[0032] A guide groove is provided on the pipe cutting cylinder fixing block 30, and the blade holder 21 moves along the guide groove to perform pipe cutting; the straw clamping block 23 is connected to the pipe cutting cylinder 22, and the clamping and loosening of the straw are achieved by opening and closing the cylinder.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
