DETAILED DESCRIPTION

[0024] The application will be further described in detail below with reference to the drawings.

[0025] The embodiment discloses a stringing machine capable of processing soft bags, like Figures 1-7As shown, including a bag storage rack 1 storing a plurality of bags, bag conveying mechanism 2, punching mechanism 3 and rope threading mechanism 4, the bag storage rack 1 is provided with a bag outlet mechanism 11 for moving the bag on the bag storage rack 1 to the bag outlet position; the bag conveying mechanism 2 comprises a conveying channel 7 and a bag taking clamp 8 and a bag holding assembly 10 reciprocating along the conveying channel; can refer to Figures 2-3 The bag taking clamp 8 clamps at the bag opening of the bag and can move the bag from the bag outlet position to the conveying channel 7; in this embodiment, the bag taking clamp comprises two clamping plates and a telescopic cylinder, the bag taking clamp 8 clamps the bag 19 through the telescopic cylinder, and during the process, the bag taking clamp clamps at the bag opening of the bag 19, so that the bag opening is effectively fixed, and the bag 19 naturally falls down under the action of gravity. Compared with the prior art, clamping at the bag opening can better fix the soft bag and prevent it from shaking and bending during conveying. The bag holding assembly 10 comprises a bag holding clamp A 10a and a bag holding clamp B 10b arranged in front of and behind the conveying channel 7, and the position of the bag taking clamp 8 clamping the bag is vertically offset from the position of the bag holding clamp A 10a clamping the bag. The bag holding clamp A 10a is used to take the bag 19 on the bag taking clamp 8 and move to the punching mechanism 3. Thus, the vertical offset of the clamping positions can ensure that the bag holding clamp A can smoothly take the bag 19 from the bag taking clamp. At the same time, after the punching mechanism 3 punches, the bag can stay at the punching mechanism 3, and when the bag holding clamp A 10a releases and takes the bag to the bag taking clamp 8, the bag holding clamp B 10b can take the punched bag to move to the rope threading mechanism 4. Through the above structure, after punching is completed, the punching mechanism does not release the bag first, but the bag holding clamp A 10a releases the bag first to take the bag to the bag taking clamp 8. During the process, the bag holding clamp B 10b moves to the punching mechanism 3, and then the bag holding clamp B holds the bag, the punching mechanism releases the bag, and the bag holding clamp B 10b moves the bag to the rope threading mechanism 4 for rope threading. At the same time, the bag holding clamp A 10a moves the next bag to the punching mechanism for punching and repeats the above process. Thus, through the cooperation of the bag holding clamp A 10a, the punching mechanism 3 and the bag holding clamp B 10b, the bag can be alternately clamped and conveyed, realizing continuous work.

[0026] Further, referring to Figure 6 The punching mechanism 3 comprises a telescopic cutter head 301 and a cutter groove 302 corresponding to the cutter head 301. The cutter head 301 can pass through the bag and be inserted into the cutter groove 302 to punch. After punching, the cutter head 301 stays in the cutter groove 302 to limit the bag to stay at the punching mechanism 3. Through the above structure, the bag stays most simply, only needs to delay for a period of time after the cutter head 301 extends to punch, and does not need to additionally set components, which is very convenient.

[0027] Further, the bag clamping clamp A 10a and the bag clamping clamp B 10b are clamped below and close to the bag opening position of the bag opening. Since the bag opening of the bag body needs to be punched and threaded, the bag clamping clamp A and the bag clamping clamp B are clamped below and close to the bag opening position, so as not to hinder the punching and threading of the upper part of the bag body, and because the clamping position is close to the bag opening, the bag opening can be kept from shaking and bending, ensuring the smooth progress of the subsequent punching and threading process.

[0028] Further, the conveying channel 7 is provided with a pair of second reciprocating tracks 6, and the second reciprocating tracks 6 are provided with a conveying plate 9 moving back and forth, and the bag clamping clamp A 10a and the bag clamping clamp B 10b are respectively arranged at both ends of the conveying plate 9. Through the above structure, the bag clamping clamp A and the bag clamping clamp B move synchronously. When the bag clamping clamp A 10a moves to the bag taking clamp direction to take the bag, the bag clamping clamp B moves synchronously to the punching mechanism 3, and when the bag clamping clamp A moves to the punching mechanism 3, the bag clamping clamp B moves synchronously to the threading mechanism 4. The two cooperate to move, and the conveying efficiency is high.

[0029] Further, the conveying channel 7 is provided with a first reciprocating track 5, and the bag taking clamp 8 moves back and forth on the first reciprocating track 5. Among them, the first reciprocating track extends to the bag taking position 17 of the bag storage rack 1, and the first reciprocating track is preferably a straight track, so that the bag taking clamp 8 can move back and forth between the conveying channels at the bag taking position of the bag storage rack.

[0030] Further, the punching mechanism 3 is provided with a limiting frame 12, and the end of the limiting frame 12 is provided with a trumpet structure, so that when the bag body 19 enters the punching mechanism 3, it can be guided into the limiting frame 12 with the trumpet structure. Through the above structure, the upper part of the bag body is further constrained and guided, and the punching position is guaranteed to be accurate.

[0031] Further, the bagging mechanism 11 comprises a base, a suction cup mechanism 1101 for sucking the bag body, and a blocking rack 1102 for blocking the subsequent bag bodies. Specifically, the blocking rack 1102 is provided with an elastic sheet 18 above, and the bag body is blocked by the elastic sheet 18. The bag body can overcome the constraint of the elastic sheet 18 and move to the bagging position 17 through the suction and movement of the suction cup mechanism 1101. Further, the base is provided with a translation mechanism 1103 and a rotating mechanism 1104 cooperating with the suction cup mechanism 1101. The translation mechanism 1103 is used to drive the suction cup mechanism to move horizontally, and move the bag body to the bagging position. The rotating mechanism 1104 is used to drive the suction holder to rotate. Since the soft bag material is relatively soft, the soft bags stored on the bag storage rack 1 are preferably placed horizontally, i.e. the side of the bag body is placed on the bottom for support, so that the bag body can be placed more stably and is not easy to bend and deform. Therefore, the rotating mechanism 1104 is provided, and the bag body is rotated while the translation mechanism 1103 moves the bag, so that the horizontally placed bag body is rotated to be placed vertically with the bag opening upward, so as to be clamped by the bag taking clamp 8. Through the bagging mechanism 11, the bag bodies stacked together can be separated one by one, and the bag taking clamp 8 can take the bags at the bagging position.

[0032] Further, the string threading mechanism 4 comprises a bag opening device 16 and a chuck pulling-out device 14. The bag opening device 16 comprises bag opening suction cups 1601 on both sides of the conveying channel, which can move towards each other. The chuck pulling-out device 14 comprises a chuck clamp jaw 15 that can be lifted and lowered, which is used to clamp the chuck on the string. After the bag opening, the lifting plate 1401 drives the chuck clamp jaw 15 to descend, and the chuck clamp jaw 15 clamps the chuck on the string and then pulls the string. During the process, the lifting plate 1401 rises synchronously, so that the chuck can be pulled out. Further, a conveyor belt 13 is arranged below the string threading mechanism 4, which is used to convey the processed bag bodies outward. Through the above structure, after the chuck is pulled out, the bag holding clamp B is released, and the bag body naturally falls onto the conveyor belt 13 and is then conveyed outward, which facilitates the collection of the processed bag bodies.

[0033] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. within the design concept of the present application shall be included in the protection scope of the present application.
