[0002] Regardless of the recycling of waste edge materials from slitting machines or blown film machines, the synchronous winding and recycling method is usually adopted. In this winding method, a torque motor drives a reel, and the reel rotates with torque to wind synchronously. For example, Chinese Patent No. 200910029954.4 discloses an edge collecting device for a slitting machine. The edge collecting cylinder is installed on the edge collecting frame, and power is input by a motor. The guide edge wheels entering the edge collecting mechanism are fixed after being adjusted to an appropriate position.

[0003] For the above-mentioned existing technology, the following problems still exist: During the winding process, if the waste edge has a cut (which may occur during the process production), due to the action of the tensile force, the waste edge will surely break, and only the machine can be stopped to manually wind the broken head onto the reel again. This seriously affects the quality and efficiency of the slit film roll, consumes the reel at the same time, and it is time-consuming for unloading and loading the reel, and the control requirements are relatively high. Summary of the Utility Model

[0027] The following will specifically describe the preferred embodiments of the present utility model in conjunction with the accompanying drawings. The accompanying drawings form a part of this application and are used together with the embodiments of the present utility model to explain the principle of the present utility model, rather than to limit the scope of the present utility model.

[0028] As Figures 1-4As shown in the figure, the utility model provides a waste edge vacuum recovery device, which includes a suction part 1, a pusher part 2 and a discharging part 3. The suction part 1 includes a vacuum pump 11, a vacuum box 12, a suction pipe 13 and a perforated plate 14. The perforated plate 14 is arranged inside the vacuum box 12. The suction pipe 13 and the vacuum pump 11 are both connected to the vacuum box 12 and are respectively located above and below the perforated plate 14. Under the suction of the vacuum pump 11, a negative pressure is formed in the vacuum box 12, and a strong suction force is generated at the suction pipe 13, so that the waste edge is sucked into the vacuum box 12 and stays on the perforated plate 14 for storage. An opening 101 with a bottom flush with the top surface of the perforated plate 14 is provided on one side of the vacuum box 12. The opening 101 is used to communicate with the discharging part 3. Under the action of the pusher part 2, the waste edge in the height range of the opening 101 of the vacuum box 12 is transferred to the discharging part 3; the pusher part 2 is arranged in the opening 101 and is used to push the waste edge material deposited on the perforated plate 14 out of the vacuum box 12 to the discharging part 3 and close the opening 101 to cut off the waste edge. Since the waste edge is in a continuous process of entering the vacuum box 12, when transferring, the front and rear waste edges are still in a single or entangled state. Therefore, after the transfer, the waste edge between the vacuum box 12 and the discharging part 3 needs to be cut off to separate it. That is, after the waste edge is pushed into the discharging part 3, it is immediately cut off at the middle position, that is, at the opening 101, so that the waste edge in the discharging part 3 and the vacuum box 12 is disconnected. And after the cutting, the opening 101 is also closed to avoid air leakage when the discharging part 3 is opened for discharging, and to maintain the negative pressure environment in the vacuum box 12; the discharging part 3 is arranged on one side of the opening 101 and is used to receive the waste edge material pushed out and cut off by the pusher part 2 and discharge the material when the opening 101 is closed, so that the waste edge can be continuously recycled without stopping the machine for cleaning.

[0029] In one embodiment, in order to suck the materials corresponding to the actual number of waste edges, the suction pipe 13 includes a horizontal pipe 131, a vertical pipe 132 and a conical hopper 133. One end of the horizontal pipe 131 is closed, and the other end is connected and communicated with the vacuum box 12. A plurality of vertical pipes 132 are arranged on the top of the horizontal pipe 131 and are communicated with it. Among them, the number of vertical pipes 132 is the same as the actual number of waste edges, and the distribution spacing also matches the actual position of the waste edges to suck the waste edges one by one.

[0030] Furthermore, in order to improve the success rate of sucking the waste edge and entering the vertical pipe 132, the conical hoppers 133 are respectively arranged on the tops of the vertical pipes 132 to guide the falling waste edges so that they can enter the vertical pipes 132 along the conical hoppers 133 under the suction air flow.

[0031] In one embodiment, in order to have the function of clearing and pushing the waste edges in the vacuum chamber 12 while also having the effect of closing the open end 101, the pushing part 2 includes a partition board 21, a rotating mechanism 22, a telescopic mechanism 23, and a cutting knife 24. The rotating mechanism 22 is installed on the vacuum chamber 12, and its movable end is connected to the partition board 21 for driving the partition board 21 to rotate and push materials within the open end 101. The partition board 21 rotates into the vacuum chamber 12 to push the waste edge materials, rotates 180°, and pushes the waste edge materials into the discharging part 3. Among them, the telescopic mechanism 23 is arranged inside the partition board 21, that is, a receiving groove space is opened at the top of the partition board 21, and the telescopic mechanism 23 is installed in this space. In addition, the cutting knife 24 is arranged at the movable end of the telescopic mechanism 23 and is located at the top of the partition board 21. The length of the cutting knife 24 matches the length of the partition board 21, and part of it is also located in the receiving groove for telescoping. The telescoping of the cutting knife 24 is used to move upward and abut against the inner top wall of the open end 101 to cut off the waste edge materials and close the open end 101.

[0032] It can be understood that when the partition board 21 is inserted into the open end 101 in a flush manner and the cutting knife 24 extends upward and abuts against the inner top wall of the open end 101, the closing of the open end 101 is formed and the waste edge is cut; in addition, in order to prevent the cut waste edge from being clamped, the telescoping of the cutting action can be performed two or three times.

[0033] It can be understood that the rotating mechanism 22 can adopt a stepper motor with a rotation amplitude of 180° each time; the telescopic mechanism 23 can adopt a cylinder push rod; as long as the rotating mechanism 22 and the telescopic mechanism 23 can respectively achieve rotation drive and telescopic drive, there is no unique limitation here.

[0034] In one embodiment, in order to collect and discharge the discharged and cut waste edges, the discharging part 3 includes a discharging box 31 and a bottom cover assembly 32. The bottom cover assembly 32 is arranged at the bottom of the discharging box 31 in an openable and closable manner for opening and closing the bottom of the discharging box 31 for discharging. The internal space height of the discharging box 31 is at least sufficient for the partition board 21 and the cutting knife 24 thereon to enter without interfering with its rotation.

[0035] It can be understood that since the negative pressure environment in the vacuum chamber 12 needs to be maintained, therefore, when opening and closing the bottom of the discharging box 31, it needs to be carried out when the open end 101 is closed, and the waste edge falls downward by its own weight for discharging.

[0036] Furthermore, if it is necessary to shred the waste edges, a cutting mechanism can also be arranged in the discharging box 31 to shred the waste edges. A cutting assembly that moves up and down can be adopted, hovering above the height of the partition board 21, and descending for cutting when the partition board 21 returns to the open end 101.

[0037] In one embodiment, in order to comprehensively clean and push the waste edge coverage area in the vacuum box 12, the shape of the vacuum box 12 is semi-circular, and its diameter matches the length of the partition plate 21, so that when rotating, it can cover the entire cross-sectional area.

[0038] In one embodiment, in order to have a better sealing effect when abutting against the inner top wall of the open end 101, the cutting knife 24 includes a base 241, a tip 242 and a sealing gasket 243. The tip 242 is arranged on the top of the base 241, and the base 241 is connected to the telescopic mechanism. The sealing gasket 243 is arranged on the top of the base 241 and is located on both sides of the tip 242. A groove 244 opposite to the tip 242 is provided on the inner top wall of the open end 101. During lifting and lowering, the tip 242 abuts against the groove 244 to cut the waste edge. After cutting, it descends to allow the waste edge to slide off, and then rises to abut the sealing gasket 243 against the inner top wall of the open end 101 to form a seal.

[0039] In one embodiment, in order to open and close the bottom of the discharge box 31, the bottom cover assembly 32 includes a cover body 321, a connecting rod 322 and a linear drive member 323. The linear drive member 323 is installed on the discharge box 31, and its movable end is connected to the connecting rod. The cover body 321 is arranged at the bottom of the connecting rod and fits with the bottom of the discharge box 31. By the telescopic movement of the linear drive member 323, the connecting rod 322 and the cover body 321 are driven to move to form an opening and closing action.

[0040] It can be understood that the linear drive member 323 can adopt a hydraulic push rod, as long as it can achieve the linear telescopic function, and it is not uniquely limited here.

[0041] In one embodiment, in order to collect the discharged waste edge material, a receiving component 4 is further included, which is arranged below the discharging part 3 and is used for collecting the waste edge material.

[0042] Specifically, the receiving component 4 includes a support frame 41 and a collection bag 42. The support frame 41 is installed on one side of the vacuum box 12 and is located directly below the discharge box 31. The collection bag 42 is hung on the support frame 41, and the waste edge material is collected through the collection bag 42.

[0043] Furthermore, the support frame 41 includes a square frame 411 and hooks 412. A plurality of the hooks 412 are evenly arranged on the outer periphery of the frame. Hanging holes 421 corresponding to the hooks 412 one by one are provided on the collection bag 42. Through the cooperation of the hooks 412 and the hanging holes 421, it is convenient to hang and connect the collection bag 42 with the support frame 41 and to take it.

[0044] The specific working process of the present utility model: Start the vacuum pump 11 to form a negative pressure in the vacuum chamber 12, generate suction at each vertical pipe 132 of the suction pipe 13, and suck the waste edge materials into the vacuum chamber 12; First, drive the partition plate 21 to rotate 180° through the rotating mechanism 22 to push the waste edge materials into the discharge box 31, then push up the cutting knife 24 through the telescopic mechanism 23 for cutting, and make the sealing gasket 243 abut against the inner top wall of the open end 101 for sealing. Then, move the cover body 321 to open the bottom of the discharge box 31, let the waste edge materials fall into the collection bag 42 for collection, and finally move the cover body 321 again to close the bottom of the discharge box 31.

[0045] The entire working process ends, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0046] As mentioned above, only the preferred specific embodiments of the present utility model are described, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
