DETAILED DESCRIPTION

[0017] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] The utility model provides a paper tube feeding and conveying mechanism, comprising a device housing front plate 1, a device housing rear plate 2, a linear reciprocating moving mechanism 3, a push frame 4, a first supporting rod 5, a second supporting rod 6 and a paper tube transporting automatic clamp 7;

[0022] The two ends of the linear reciprocating mechanism 3 are respectively fixed on the front plate 1 of the equipment housing and the rear plate 2 of the equipment housing. The front plate 1 of the equipment housing is provided with a circular opening 11. The first supporting rod 5 and the second supporting rod 6 are respectively arranged on both sides of the linear reciprocating mechanism 3, and their length direction is consistent with the length direction of the linear reciprocating mechanism 3. The push frame 4 is fixed on the actuator of the linear reciprocating mechanism 3, and the height value of the push frame 4 is greater than or equal to the outer diameter of the paper tube 9. The automatic clamping claw 7 for transporting the paper tube is arranged in front of the front plate 1 of the equipment housing.

[0023] The basic working principle of the utility model is as follows: a plurality of paper tubes 9 are placed in a row on the first supporting rod 5 and the second supporting rod 6, and the end faces of two adjacent paper tubes 9 are fitted together, the circumferential surface of the paper tube 9 is supported by the first supporting rod 5 and the second supporting rod 6, and the rear end face of the last paper tube 9 is against the push rack 4. When the paper tube 9 is needed, the linear reciprocating mechanism 3 is started, and the actuator starts to move forward, thereby driving the push rack 4 to move forward, so that the push rack 4 pushes the front side of all paper tubes 9 to move, until the frontmost paper tube 9 moves to a position where the automatic clamp 7 of the transport tube can grab it, and then the actuator stops moving. When the paper tube 9 is to be fed, the circular opening 11 allows the front plate 1 of the equipment housing of the frontmost paper tube 9 to extend outward a part to facilitate the clamping of the automatic clamp 7 of the transport tube.

[0024] Since the paper tube 9 is relatively rough and the end faces of two adjacent paper tubes 9 are in contact with each other, the friction is relatively large. When the automatic paper tube transport clamp 7 clamps the previous paper tube 9 away, the next paper tube 9 is often moved along with it, causing the next paper tube 9 to tilt, thereby affecting the automatic paper tube transport clamp 7's gripping of the tilted paper tube 9.

[0025] Therefore, the utility model also includes a paper tube separation mechanism, which includes a front push cylinder 81 and a rear push cylinder 82. The automatic paper tube transport clamp 7 is arranged in front of the front plate 1 of the equipment housing, and the first supporting rod 5 and the second supporting rod 6 extend a part of the paper tube transport clamp 7 from the circular opening 11 to the front side; the automatic paper tube transport clamp 7 includes an arm plate 71 and an upper clamping part 72 and a lower clamping part 73 fixed on the arm plate 71, the upper clamping part 72 and the lower clamping part 73 can approach and move away from each other, and the height of the lower clamping part 73 is lower than the height of the first supporting rod 5 and the second supporting rod 6. The front push cylinder 81 is fixed to the outer side surface of the front plate 1 of the equipment housing, and its telescopic rod faces the automatic paper tube transport clamp 7. The rear push cylinder 82 is fixed to the rear side surface of the arm plate 71, and its telescopic rod faces the front plate 1 of the equipment housing, and the height of the front push cylinder 81 is lower than the height of the first supporting rod 5 and the second supporting rod 6.

[0026] When paper tube 9 is needed to be fed, the frontmost paper tube 9 is directly pushed to be separated from the first supporting rod 5 and the second supporting rod 6, and the paper tube 9 falls from the first supporting rod 5 and the second supporting rod 6 to the lower clamping part 73. At this time, the lower clamping part 73 supports the circumferential surface of the paper tube 9, and the telescopic rod of the rear push cylinder 82 just contacts the front end surface of the feeding paper tube 9, and the feeding paper tube 9 and the adjacent paper tube 9 at the back are still in contact with each other. Then the telescopic rod of the back-pushing cylinder 82 is extended, and the paper tube 9 of the feeding and the paper tube 9 behind it are pushed toward the front plate 1 of the equipment housing, and the rear end face of the feeding paper tube 9 contacts the telescopic rod of the front-pushing cylinder 81, and the paper tube 9 adjacent to the back of the feeding paper tube 9 retreats to the rear side of the telescopic rod of the front-pushing cylinder 81, so that the push plate is located between the feeding paper tube 9 and the paper tube 9 adjacent to the back. Since the height of the lower clamping portion 73 is lower than the first supporting rod 5 and the second supporting rod 6, the bottom of the feeding paper tube 9 will extend downward relative to the paper tube 9 adjacent to the back, so as to facilitate the front-pushing cylinder 81 to push the feeding paper tube 9 toward the automatic clamping jaw 7 of the transport cylinder (pushing the extended part). Of course, before the front-pushing cylinder 81 pushes the feeding paper tube 9 alone, the telescopic rod of the back-pushing cylinder 82 needs to be retracted. After the front-pushing cylinder 81 pushes the feeding paper tube 9 toward the automatic clamping jaw 7 of the transport cylinder, the feeding paper tube 9 is finally separated from the paper tube 9 adjacent to the back.

[0027] The linear reciprocating mechanism 3 of the utility model is a slide 31 cylinder, including a slide 31 and a guide rod 32 . The slide 31 can slide back and forth on the guide rod 32 , and the push frame 4 is fixed on the slide 31 .

[0028] The push frame 4 in the utility model includes a connecting plate 41, a first support rod 42, a second support rod 43 and a reinforcing rod 44. The connecting plate 41 is fixed on the slide 31, the bottom end of the first support rod 42 and the bottom end of the second support rod 43 are respectively fixed on the connecting plate 41, and the two ends of the reinforcing rod 44 are respectively fixed on the top end of the first support rod 42 and the top end of the second support rod 43. The connecting plate 41 mainly plays the role of connecting the first support rod 42, the second support rod 43 and the slide 31, and the main function of the first support rod 42 and the second support rod 43 is to directly push the paper tube 9. The reinforcing rod 44 plays the role of reinforcing the parallel position relationship between the first support rod 42 and the second support rod 43.

[0029] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
