[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] Example 1

[0029] Please refer to Figures 1 to 6 A preferred embodiment of the present invention provides an automatic pipe capping device, which mainly includes a bracket 1, a conveyor belt 2 and a torsion slide 3.

[0030] Please refer to Figure 1 The conveyor belt 2 is mounted on the support 1 to transport pipes. The conveyor belt 2 includes a driving pulley 22, a transmission pulley 23, a transmission motor 24, and a conveyor belt 25. The conveyor belt 25 is a closed-loop structure, tensioned between the driving pulley 22 and the transmission pulley 23. The driving pulley 22, the transmission pulley 23, and the transmission motor 24 are mounted on the support 1. The transmission motor 24 is connected to the driving pulley 22 and drives the driving pulley 22 to rotate. The conveyor belt 25 is transversely provided with a plurality of grooves 21 for receiving pipes. During operation, the transmission motor 24 is activated to drive the driving pulley 22 to rotate. The transmission belt 25 is driven by the driving pulley 22 and the driven pulley 23. The pipes placed in the grooves 21 are transported from the front end to the rear end along with the transmission belt 25 and eventually separated from the transmission belt 25. The support 1 is provided with multiple transversely arranged horizontal shafts 12, each of which is equipped with rollers 13. The rollers 13 are located below the conveyor belt 25. The arrangement of the horizontal shaft 12 and the roller 13 can support the conveyor belt 25, especially the conveyor belt 25 on which the pipe is placed, so that the pipe transmission is more stable and smooth.

[0031] Please refer to Figure 1 There are two twisting slides 3, which are respectively arranged on both sides of the conveyor belt 2 for conveying the caps. The ends of the twisting slides 3 gradually approach the conveyor belt 2 and face the conveyor belt 2, so that when the caps are transported from the front end to the rear end of the twisting slide 3, the caps can enter the two end ports of the pipe conveyed by the conveyor belt 2.

[0032] As a preferred embodiment, please continue to refer to Figure 1 and Figure 3The twisting slide 3 includes a lid receiving portion 31 at the front, a lid twisting conveying portion 32 at the middle, and a closing portion 33 at the rear. The receiving portion 31 is set upward to allow the lid to enter; the closing portion 33 is close to the conveyor belt 2 and faces the conveyor belt 2 to allow the lid to enter the port of the pipe; the twisting conveying portion 32 is gradually twisted to connect the receiving portion 31 and the closing portion 33 to convey the lid. In a preferred embodiment, the ends of the two closing portions 33 are set in detail, and the distance between the two is equal to the length of the pipe to ensure that the lid can enter the port of the pipe in sufficient quantity. Both sides of the twisting slide 3 are provided with a slide groove 34 for the end convex edge of the lid to enter and slide, so as to ensure that the lid can slide smoothly on the twisting slide 3 and will not fall out of the twisting slide 3. The front end of the receiving portion 31 is set to be larger at the front and smaller at the back to ensure that the lid can enter smoothly. In order to achieve smooth sliding of the lid, the twisting slide 3 is set to be higher at the front (end) and lower at the back (end). Accordingly, please refer to Figure 1 The front of the conveyor belt 2 is horizontally arranged, and the rear is tilted downward. The torsion slide 3 is correspondingly arranged at the rear of the conveyor belt 2. The torsion slide 3 is flush with the height of the conveyor belt 2 at the corresponding position, thereby ensuring that the cap can smoothly enter the port at the end of the pipe. The front of the conveyor belt 2 is horizontally arranged, and the rear is tilted downward. The tilted rear end also facilitates the removal of the pipe after the cap is added.

[0033] When implementing, please refer to Figure 7 and Figure 8 After the cover 6 enters the end of the pipe 5, it moves along with the pipe 5 under the action of the conveyor belt 2, and finally leaves the torsional slide 3 from the end of the transmission belt 2, and the covering work is completed. The adding speed and sliding of the cover 6 can be adjusted together according to the transmission of the pipeline 5 to ensure that each pipeline 5 can be covered with a cover 6 and that each cover 6 can enter the port of the pipeline 5.

[0034] In a preferred embodiment, please refer to Figure 1 and Figure 7The bracket 1 is provided with an adjustment plate 11 at both sides of the front end of the conveyor belt 2. The two adjustment plates 11 are arranged opposite to each other and form a closing structure with a larger front and a smaller rear end. The distance between the rear end closing points of the two adjustment plates 11 is equal to the length of the pipe to be covered. When the pipe 5 is placed on the groove 21, especially when placed manually, it is difficult to ensure that the pipe 5 is placed symmetrically along the center line of the conveyor belt 2. The two adjustment plates 11 are provided. When the pipe 5 is placed, the two adjustment plates 11 are arranged opposite to each other and form a closing structure with a larger front and a smaller rear end. The distance between the rear end closing points of the two adjustment plates 11 is equal to the length of the pipe to be covered. Therefore, under the action of the two adjustment plates 11, the position of the pipe 5 can be adjusted so that the pipe 5 is placed symmetrically along the center line of the conveyor belt 2, so as to ensure that the covers 6 at both ends can smoothly enter the two end ports of the pipe 5 at the same time.

[0035] In a preferred embodiment, in order to achieve automatic, uniform and controllable lid addition, in this preferred embodiment, please refer to Figure 2 The automatic pipe capping device also includes a cap separation and dropping mechanism 4. There are two cap separation and dropping mechanisms 4, each located above the front end of the two torsion slides 3. The cap separation and dropping mechanism 4 includes a cap feed pipe 41, a stop fork 43, a support rod 44, and a drive mechanism for driving the stop fork 43 and the support rod 44. The cap feed pipe 41 is fixedly mounted on the bracket 1. The cap feed pipe 41 is arranged upright, with open ends at the top and bottom. The pipe is used to place multiple caps. The bottom side wall of the cap feed pipe 41 is provided with a side hole for the fork of the stop fork 43 to enter. The open lower end is located directly above the front end of the torsion slide 3. The fork head of the stop fork 43 is a V-shaped or U-shaped forked structure. In this preferred embodiment, the fork head of the stop fork 43 is a U-shaped forked structure. The fork head of the stop fork 43 is larger than the tapered portion 62 of the lid 6 and smaller than the convex edge 61 of the lid 6, so that the stop fork 43 can support the convex edge 61 of the lid 6 through the fork head without affecting the lid below.

[0036] The driving mechanism is respectively connected to the stop fork 43 and the supporting rod 44, for driving the fork head of the stop fork 43 to penetrate into the side hole of the bottom side wall of the lid feeding tube 41 to support the second to last lid at the bottom or driving the fork head of the stop fork 43 to leave the side hole of the bottom side wall of the lid feeding tube 41; and for driving the end of the supporting rod 44 to be located at the lower end opening of the lid feeding tube 41 to support the bottommost lid or driving the end of the supporting rod 44 to leave the lower end opening of the lid feeding tube 41; and the stop fork 43 and the supporting rod 44 alternately approach or move away from the lid feeding tube 41.

[0037] Preferably, please refer to Figure 2The drive mechanism includes a support frame 48, a limiting post 42 mounted on the support frame 48, a rotating shaft 45, and a motor 46 for driving the rotating shaft 45. The support frame 48 is fixedly mounted on the bracket 1. The limiting post 42 has two limiting holes defined from top to bottom. The stop fork 43 passes through the upper limiting hole, and the support rod 44 passes through the lower limiting hole. A driving gear 410 is provided on the output shaft of the motor 46, and the rotating shaft 45 is arranged on the support frame 48 through a bearing. A driven gear 412 meshing with the driving gear 410 is provided on the rotating shaft 45, and two cranks 413 facing in opposite directions (roughly in two opposite directions, but not necessarily strictly parallel) are provided at the two ends of the rotating shaft 45. The cranks 413 are arranged perpendicular to the rotating shaft 45, and the ends of the cranks 413 are fixedly connected to the ends of the rotating shaft 45. One of the cranks 413 is connected to the rear end of the stop fork 43 through the first connecting rod 47, and the other crank 413 is connected to the rear end of the supporting rod 44 through the second connecting rod 49. The two ends of the first connecting rod 47 are respectively rotatably connected to the crank 413 and the stop fork 43, and the two ends of the second connecting rod 49 are respectively rotatably connected to the crank 413 and the supporting rod 44.

[0038] Please refer to Figures 3 to 6 The motor 46 starts to drive the driving gear 410 to rotate, so that the driven gear 412 rotates and drives the rotating shaft 45 to rotate. When the rotating shaft 45 rotates, it drives the crank 413 to rotate. The crank 413 rotates around the axis of the rotating shaft 45, thereby driving the first connecting rod 47 and the second connecting rod 49 to move. Under the action of the first connecting rod 47 and the second connecting rod 49, the material stop fork 43 and the material support rod 44 make a back and forth reciprocating motion under the action of the limiting hole of the limiting column 42. When implementing, please refer to Figure 4 , multiple lids are stacked in the lid feeding tube 41 (the convex edge of the lid is at the bottom), the end of the supporting rod 44 is located at the lower open end of the lid feeding tube 41 to support the lid at the bottom, and the fork of the stop fork 43 leaves the side hole of the bottom side wall of the lid feeding tube 41. At this time, the lid at the bottom (of course including the lid above it) is supported by the end of the supporting rod 44, and the motor 46 runs, driving the driving gear 410, the driven gear 412, the rotating shaft 45, the crank 413 and the first connecting rod 47 and the second connecting rod 49 to operate. At this time, the stop fork 43 moves toward the lid feeding tube 41, and the supporting rod 44 moves away from the lid feeding tube 41. Please refer to Figure 5 , continue to move, at this time the fork of the stop fork 43 penetrates the side hole of the bottom side wall of the lid feeding tube 41 to support the bottom of the second to last lid convex edge, and the end of the supporting rod 44 leaves the lower end opening of the lid feeding tube 41, please refer to Figure 6The lid 41 is then released from the bottom of the feed pipe 41 and the lid 42 is released from the bottom of the feed pipe 41. The lid 41 is then released from the bottom of the feed pipe 41 and the lid 42 is released from the bottom of the feed pipe 41. Figure 4 In the illustrated situation, the motor 46 keeps running and the operation is repeated, so that the lids can be added continuously, automatically, orderly, at a uniform speed and in a controllable manner.
