[0036] like Figure 1As shown, the automatic wrap tube bagging device includes a workbench 800, on which a bag feeding device 500, a bag opening device 400, a bag lifting device 300 and a wrap tube feeding device are installed. The bag lifting device 300 is located above the bag feeding device 500, and the bag lifting device 300 separates the annular bags on the bag feeding device 500. The bag opening device 400 is located at one side of the bag feeding device 500, and the bag opening device 400 opens the separated annular bags. The wrap tube feeding device is located in front of the bag lifting device 300, and the wrap tube feeding device feeds the wrap tube into the opened annular bag.

[0037] In this embodiment, if Figure 1 As shown, a bag taking device 700 is also installed on the workbench 800. The bag taking device 700 is located at the rear side of the bag lifting device 300, and the bag taking device 700 takes out the winding tube with the annular bag and puts it into the finished product box.

[0038] In this embodiment, if Figure 6 As shown, the bag feeding device 500 includes a support frame f501, which is installed on the workbench 800. A box body 503 for placing an annular bag and a telescopic component 504 are installed on the support frame f501. The telescopic component 504 is located below the box body 503. A lifting cylinder a505102 is installed on the telescopic component 504. A suction cup b507 for sucking the annular bag out of the box body 503 is installed on the piston rod of the lifting cylinder a505102. The telescopic component 504 extends to send the suction cup b507 to the bottom of the bag lifting device 300. After the telescopic component 504 retracts, the suction cup b507 is located below the box body 503. The lifting cylinder a505102 extends so that the suction cup b507 is located below the box body 503. The suction cup b507 works, thereby sucking the annular bag onto the suction cup b507. , then the lifting cylinder a505102 resets, the annular bag is brought out of the box body 503, and then the telescopic assembly 504 extends, the suction cup b507 moves toward the bag lifting device 300, and finally is located below the bag lifting device 300. In this embodiment, the telescopic assembly 504 includes a first cylinder and a second cylinder. The first cylinder is installed on the side wall of the support frame f501. The first cylinder is provided with a guide rail. The second cylinder is installed on the first cylinder, and the first cylinder works so that the second cylinder moves along the guide rail. The second cylinder is also provided with a guide rail, and a moving frame is slidably installed on the guide rail. The piston rod of the second cylinder is connected to the moving frame, and the lifting cylinder a505102 is installed on the moving frame. Of course, according to actual needs, more cylinders can be set to meet the requirements of the moving distance of the suction cup b507.

[0039] In this embodiment, if Figure 7 and Figure 8As shown, a discharge port is provided at the top of the box body 503, and a discharge port 517 is provided at the bottom of the box body 503. Rotatable rollers 518 are installed on the two side walls of the discharge port 517, and the distance between the two rollers 518 is smaller than the width of the annular bag. The annular belt can be put into the box body 503 through the discharge port, and the annular bag is stacked in the box body 503. Since the annular bag is light, a pressing plate 513 can be placed in the box body 503, so that the annular bag is pressed. The annular bag is held in place to prevent it from becoming fluffy, and after the annular belt is pressed, the edge of the annular bag at the bottom is located on the roller 518, and when the suction cup b507 sucks the annular bag and causes the annular bag to separate from the box body 503, the annular bag slides along the outer circle of the roller 518, and when the friction force is large enough, the roller 518 will rotate, so when the annular bag separates from the box body 503, the annular bag can separate from the box body 503 smoothly without creases, thereby ensuring that the shape of the annular bag is regular.

[0040] In this embodiment, if Figure 7 and Figure 8 As shown, an L-shaped plate 502 is also installed on the top of the support frame f501, and the box body 503 is installed on the vertical plate of the L-shaped plate 502. Furthermore, a mounting block 519 is provided on the side of the box body 503 close to the L-shaped plate 502, and an adjustment groove 516 is opened on the L-shaped plate 502. A locking piece 515 is installed in the adjustment groove 516. The locking piece 515 is threadedly matched with the screw hole on the mounting block 519. Therefore, the position of the locking piece 515 in the adjustment groove 516 can be adjusted according to actual conditions, thereby adjusting the position of the box body 503. After adjustment, the locking piece 515 can be locked. In order to ensure the stability of the installation of the box body 503, multiple mounting blocks 519 can be set on the box body 503.

[0041] In this embodiment, if Figure 7 and Figure 8 As shown, one side wall of the box body 503 in the width direction is a detachable side wall, and the detachable side wall is a limit plate 509. The limit plate 509 can slide along the inner cavity of the box body 503. The size of the inner cavity of the box body 503 can be adjusted by adjusting the position of the limit plate 509. A locking hole 511 is provided on the top of the side wall of the box body 503. The pressure block 510 is installed on the top of the box body 503 by a locking screw 512, and the locking screw 512 is threadedly matched with the locking hole 511. When the pressure block 510 is locked, the pressure block 510 presses the limit plate 509, so that the position of the limit plate 509 is fixed.

[0042] In this embodiment, if Figure 7 and Figure 8As shown, an observation window 514 is also provided on the side wall of the box body 503 so that the operator can intuitively see the remaining amount of the annular bag, and the length of the observation window 514 should be smaller than the length of the annular bag. Furthermore, a detector 508 for detecting the remaining amount of the annular bag is also provided at the bottom of the box body 503. Optionally, the detector 508 is an infrared detector, that is, an infrared transmitter is installed on the side wall of the box body 503, and an infrared receiver is installed on the opposite side wall of the box body 503. If the infrared receiver can receive an infrared signal, it indicates that the remaining amount of the annular bag cannot meet the requirement and the annular bag should be added immediately. If the infrared receiver does not receive the infrared signal, it indicates that the remaining amount of the annular bag meets the requirement and there is no need to add the annular bag.

[0043] In this embodiment, if Figure 4 As shown, the bag lifting device 300 includes a vertical frame 301, which is installed on the workbench 800. A horizontal frame 302 is also installed on the top of the vertical frame 301. A cylinder d303 is installed on the horizontal frame 302, and the piston rod of the cylinder d303 extends toward the workbench 800. A suction cup a304 is installed on the piston rod of the cylinder d303. The suction cup a304 sucks the annular bag on the suction cup b507, and as the piston rod of the cylinder d303 retracts, the suction cup b507 separates the annular bag, the piston rod of the cylinder d303 extends downward, the suction cup a304 contacts the annular bag, and then the suction cup a304 works, and the cylinder d303 retracts a certain distance, so that the annular bag is separated. At this time, the separated annular bag presents a triangular structure.

[0044] In this embodiment, if Figure 5As shown, the bag opening device 400 includes a support frame c401, which is mounted on the workbench 800, and a cylinder e402 is mounted on the support frame, the piston rod of the cylinder e402 is connected to a vertical plate 407, a finger slide cylinder 408 is mounted on the vertical plate 407, an upper connecting rod 409 is mounted on the upper slide seat of the finger slide cylinder 408, an upper connecting plate is mounted on the upper connecting rod 409, a lower connecting rod 410 is mounted on the lower slide seat of the finger slide cylinder 408, and the lower connecting rod 410 is mounted on the lower slide seat of the finger slide cylinder 408. A lower connecting plate 412 is installed on the upper part, and the lower connecting plate 412 is located below the upper connecting plate. The lower connecting plate 412 and the upper connecting plate enter the separated annular bags under the action of the cylinder e402, and the separated annular bags are fully opened under the action of the finger slide cylinder 408. In this embodiment, a slide rail is provided on the cylinder e402, and a slide plate b403 is installed on the slide rail. The telescopic rod of the cylinder e402 is connected to the slide plate b403, and the vertical plate 407 is installed on the slide plate b403. When the annular bag is opened, the cylinder e402 is opened. After the bags are separated, the cylinder e402 works, so that the slide plate b403 moves along the slide rail. At this time, the distance between the upper slide seat and the lower slide seat of the finger slide cylinder 408 is the smallest, so the distance between the upper connecting plate and the lower connecting plate 412 is also the smallest. In order to facilitate the insertion of the upper connecting plate and the lower connecting plate 412 into the annular bag, the insertion ends of the upper connecting plate 411 and the lower connecting plate 412 are arc-shaped structures. When the upper connecting plate 411 and the lower connecting plate 412 are inserted into the annular bag, the cylinder e402 stops working and the finger slide cylinder stops working. The cylinder 408 works to move the upper connecting plate upward and the lower connecting plate 412 downward, so that the annular bag is fully opened. After the annular belt is fully opened, the annular belt is rectangular. Then the winding tube is pushed into the annular belt under the action of the winding tube feeding device, and then the finger slide cylinder 408 is reset. At this time, the annular bag is no longer tightened by the upper connecting plate and the lower connecting plate 412, but is tightened by the elastic restoring force of the winding tube. Then the bag taking device 700 takes out the put-on annular bag and puts it into the finished box.

[0045] In this embodiment, a cylinder f404 is also installed on the stand 407. The cylinder 404 is located below the finger slide cylinder 408. A push rod 405 is installed on the top of the piston rod of the cylinder 404. When the finger slide cylinder 408 needs to be reset, the cylinder 404 works and the push rod 405 moves upward. The push rod 405 presses against the bottom of the lower slide of the finger slide cylinder 408, thereby assisting the finger slide cylinder 408 in resetting.

[0046] In this embodiment, if Fig. 9As shown, the bag taking device 700 includes a support frame d701, and the support frame d701 is installed on the workbench 800. Two fixed seats 706 are installed on the support frame d701, and a telescopic cylinder 702 is installed between the two fixed seats 706. A mounting frame 703 is installed on the cylinder seat of the telescopic cylinder 702, and a chuck cylinder a704102 is installed on the mounting frame 703. A chuck a705 is installed on the chuck cylinder a704102. The chuck a705 takes out the winding tube with the annular bag and puts it into a finished product box. The finished product box is located on one side of the support frame d701. The telescopic cylinder 702 works to move the mounting frame 703 toward the winding tube with the annular bag, and at this time, the chuck cylinder a704102 works to open the chuck a705, and the winding tube is opened. Then it enters into the chuck a705, and then the telescopic cylinder 702 makes the chuck a705 clamp the winding tube, and the telescopic cylinder 702 resets. During the resetting process of the telescopic cylinder 702, the chuck cylinder a704102 makes the chuck a705 open again, so that the winding tube is separated from the chuck a705, and the winding tube falls into the finished product box after being separated from the chuck a705. Furthermore, the chuck a705 includes an upper chuck and a lower chuck, and the end of the upper chuck is L-shaped, so it can hook the winding tube. In this embodiment, a shuttle groove 707 is provided on the workbench 800, and the bag taking device 700 takes out the winding tube, and then the winding tube falls into the shuttle groove 707, and then the winding tube slides along the shuttle groove 707 into the finished product box, and the finished product box is located on one side of the workbench 800.

[0047] In this embodiment, the winding tube feeding device includes a shaping device 100, a compression device 200 and a pushing device 600. The shaping device 100 is located in front of the compression device 200. A slot 900 is provided on the workbench 800. The compression device 200 and the pushing device 600 are both installed on the workbench 800, and the compression device 200 and the pushing device 600 span the slot 900. The pushing device 600 is installed at the slot 900 of the workbench 800, and the pushing device 600 pushes the winding tube from the shaping device 100 to the compression device 200, and allows the winding tube to enter the opened annular bag from the compression device 200.

[0048] In this embodiment, if Figure 2As shown, the shaping device 100 includes two support frames a105, and the two support frames a105 are respectively installed on the workbench 800 on the left and right sides of the slot hole 900, and a slide rail is installed on the support frame a105, and a slide plate a103 is slidably matched on the slide rail. A cylinder a102 is installed on the support frame a105, and the piston rod of the cylinder a102 is connected to the slide plate a103. A cylinder b104 is installed on the slide plate a103, and an arc-shaped pressure plate 101 is installed on the piston rod of the cylinder b104. A support platform 107 is also installed on the inner side of the support frame a105, and a gap is left between the two support platforms 107 for the pushing device 600 to extend, and the gap is located above the slot hole 900. The arc-shaped pressure plate 101 is located above the corresponding support platform 107, and the wound winding The tube is placed on the support platform 107. At this time, the spacing between the two arc-shaped pressure plates 101 is relatively wide. After the winding tube enters the support platform 107, the winding tube will open under the action of the elastic restoring force, so that the winding tube at this time is close to a circle. Of course, the circumferential diameter of the winding tube at this time is determined by the clamping device of the clamped winding tube. Then the cylinder b104 works, so that the arc-shaped pressure plates 101 move relatively, thereby compressing the winding tube, making the winding tube elliptical. The cylinder a102 is mainly used to adjust the initial spacing of the corresponding arc-shaped pressure plates 101. Therefore, the spacing of the corresponding arc-shaped pressure plates 101 can be adjusted according to different products, thereby improving the versatility of the shaping device 100. The shaped winding tube is pushed into the compression device 200 through the pushing device 600.

[0049] In this embodiment, if Figure 3 As shown, the compression device 200 includes two support frames b203, and the two support frames b203 are respectively installed on the workbench 800 on the left and right sides of the slot hole 900. A cylinder c202 is installed on the support frame b203. The piston rod of the cylinder c202 is connected to a pressing frame 201. A gap is left between the two pressing frames 201 for the pushing device 600 to extend out. The pressing frame 201 is a rectangular structure, and the opposite surfaces of the two pressing frames 201 are open. The feeding end of the pressing frame 201 is bent outward, so that the feeding end formed by the two pressing frames 201 is a trumpet mouth.
