Description

Technical Field

[0001] This utility model relates to the field of pre-selection technology for spout bag top cover, and in particular to a spout pre-rotation device. Background Technology

[0002] A spout pouch is a flexible packaging bag with a horizontal support structure at the bottom and a spout on the top or side. Its self-standing structure allows it to stand upright without any support and regardless of whether it is opened or closed. Self-standing spout pouches are a relatively new packaging format, and their biggest advantage over common packaging is portability. During the production process, the spout cap needs to be pre-tightened to prevent misalignment between the internal threads of the spout cap and the external threads of the bottle opening.

[0003] In the prior art, Chinese utility model patent CN212769753U discloses an automatic pre-spinning cap device, including a left suction nozzle and a right suction nozzle. The left suction nozzle is mounted on the rotating shaft of a left rotating cylinder, which is fixed to the piston rod of a left telescopic cylinder. The left telescopic cylinder is fixed to one end of a rotating plate, and the middle of the rotating plate is fixed to the rotating shaft of the rotating cylinder. The right suction nozzle is mounted on the rotating shaft of a right rotating cylinder, which is fixed to the piston rod of a right telescopic cylinder. The right telescopic cylinder is fixed to the other end of the rotating plate. This utility model can continuously pre-spin the caps of wide-mouth bottles, achieving automated feeding, effectively improving work efficiency and reducing labor costs. Both the left and right suction nozzles of this utility model are made of flexible materials that can be bent. The left and right suction nozzles directly contact the bottle caps, avoiding scratches on the caps. At the same time, it simulates the flexibility of a human hand, so even if the thread starting point is not aligned, the product will not be damaged.

[0004] Problems with the existing technology: The above-mentioned automatic pre-rotating cover device cannot stably clamp various types of nozzle covers during the pre-rotating process, resulting in poor applicability of the nozzle cover pre-rotating device.

[0005] Therefore, there is an urgent need for a nozzle pre-rotation device. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pre-rotation device for a suction nozzle.

[0007] The technical problem solved by this utility model is achieved through the following technical solution: a nozzle pre-rotation device, including a frame, a worktable installed on one side of the frame, and a pre-rotation mechanism set above the worktable for automatically pre-rotating the nozzle. It also includes a clamping mechanism at one end of the pre-rotation mechanism for clamping various nozzle caps. The pre-rotation mechanism includes a lifting electric push rod, which is rotatably connected to one side of the worktable. A lifting arm is fixedly installed at the extended end of the lifting electric push rod. A drive motor is fixedly installed at one end of the lifting arm. A rotating rod is fixedly installed at the rotating end of the drive motor. An extension rod is slidably connected to the inner wall of the rotating rod. A helical spring is fixedly installed at one end of the extension rod, and a mounting base is fixedly installed at one end of the extension rod.

[0008] As a further embodiment of this utility model: the clamping mechanism includes a square tube, which is uniformly welded to the outer wall of the mounting base. A movable rod is slidably connected to the inner wall of the square tube. A compression spring is fixedly installed at one end of the movable rod, and a clamping block is fixedly installed at the other end of the movable rod. Multiple ball bearings are rotatably connected to the inner wall of the clamping block.

[0009] As a further embodiment of this utility model: a support mechanism is provided in the middle of the frame to support the opening of the suction bag. The support mechanism includes a servo motor, which is fixed to the outside of the frame by bolts. A bidirectional lead screw is fixedly installed on the rotating end of the servo motor. Side plates are connected to both sides of the bidirectional lead screw. A top rod is provided at one end of the side plate. An arc-shaped clamping plate A is fixedly installed on one side of the top rod, and an arc-shaped clamping plate B is fixedly installed on the other side of the top rod.

[0010] As a further embodiment of this utility model: multiple drive rollers are rotatably connected inside the frame, and a conveyor belt is rotatably connected to the outside of the drive rollers.

[0011] As a further improvement of this utility model: retaining rings are fixedly installed on both sides of the conveyor belt, and multiple partitions are evenly arranged on the outer wall of the conveyor belt.

[0012] As a further embodiment of this utility model: a toothed pulley is fixedly installed at one end of the drive roller, and a toothed belt is connected to the outer side of the toothed pulley.

[0013] As a further improvement of this utility model, a limit rod is slidably connected to one end of the side plate.

[0014] As a further embodiment of this utility model: a steering motor is fixedly installed above the workbench, a drive gear is fixedly installed at the rotating end of the steering motor, and a driven gear is fixedly installed at one end of the lifting electric push rod, with the drive gear meshing with the driven gear.

[0015] As a further improvement of this utility model, a support platform is fixedly installed on one side of the frame.

[0016] As a further improvement of this utility model: the inner walls of both the arc-shaped clamp A and the arc-shaped clamp B are provided with rubber pads, and a pressure sensor is fixedly installed inside the top rod.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] 1. The steering motor drives the driven gear to rotate via the drive gear, which in turn drives the lifting electric push rod to rotate. The lifting electric push rod then drives the lifting arm to rise and fall, thereby picking up the suction nozzle. Subsequently, the drive motor drives the rotating rod to rotate, allowing the mounting base to move up and down while rotating. Multiple compression springs elastically compress multiple clamping blocks, and the movable rod can slide along the inner wall of the square tube. This allows the suction nozzle pre-rotation device to stably clamp various suction nozzle covers during the pre-rotation process. At the same time, the ball bearings can rotate along the clamping blocks, reducing the friction between the clamping blocks and the suction nozzle. This allows the suction nozzle pre-rotation device to pre-rotate various sizes of suction nozzle covers, expanding its applicability.

[0019] 2. A servo motor drives a bidirectional lead screw to rotate, which causes the side plates to move closer or further apart. Under the detection of the clamping force of the top rod by a pressure sensor, the arc-shaped clamping plate A and arc-shaped clamping plate B cooperate to clamp and fix various sizes of stand-up pouches. At the same time, the conveyor belt drives multiple stand-up pouches forward in sequence, thus replacing the manual handling of the stand-up pouches and automatically supporting them. This ensures the safety of the nozzle pre-rotation and improves the automation level of the nozzle pre-rotation device. Attached Figure Description

[0034] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0035] Example 1: As Figure 1-6As shown, a nozzle pre-rotation device includes a frame 100, a worktable 200 mounted on one side of the frame 100, and a pre-rotation mechanism disposed above the worktable 200 for automatically pre-rotating the nozzle. It also includes a clamping mechanism disposed at one end of the pre-rotation mechanism for clamping various nozzle caps. The pre-rotation mechanism includes a lifting electric actuator 101, which is rotatably connected to one side of the worktable 200. The extended end of the lifting electric actuator 101 is bolted to a lifting arm 102. The lifting electric actuator 101 drives the lifting arm to move upwards and downwards. The lifting arm 102 is raised and lowered. One end of the lifting arm 102 is bolted to a drive motor 103. The rotating end of the drive motor 103 is bolted to a rotating rod 104. The drive motor 103 drives the rotating rod 104 to rotate. An extension rod 105 is slidably connected to the inner wall of the rotating rod 104. One end of the extension rod 105 is bolted to a helical spring 106, which elastically connects the extension rod 105 to the rotating rod 104. One end of the extension rod 105 is bolted to a mounting base 107. 07. A clamping mechanism for various sizes of suction nozzles is provided. A steering motor 110 is bolted to the top of the worktable 200. A drive gear 120 is bolted to the rotating end of the steering motor 110. A driven gear 130 is bolted to one end of the lifting electric push rod 101. The steering motor 110 drives the driven gear 130 to rotate via the drive gear 120. The drive gear 120 meshes with the driven gear 130, thereby causing the lifting electric push rod 101 to rotate. The clamping mechanism includes a square tube 201. The square tube 201 is uniformly welded to the outer wall of the mounting base 107. A movable rod 202 is slidably connected to the inner wall of the square tube 201. The movable rod 202 can slide along the inner wall of the square tube 201. A compression spring 203 is fixed to one end of the movable rod 202 by bolts. A clamping block 204 is fixed to the other end of the movable rod 202 by bolts. Multiple compression springs 203 elastically compress multiple clamping blocks 204. Multiple ball bearings 205 are rotatably connected to the inner wall of the clamping block 204. The ball bearings 205 can rotate along the clamping block 204 to reduce the friction between the clamping block 204 and the suction nozzle.

[0036] In this embodiment, the steering motor 110 drives the driven gear 130 to rotate via the drive gear 120. The driven gear 130 drives the lifting electric push rod 101 to rotate, and the lifting electric push rod 101 drives the lifting arm 102 to rise and fall, thereby picking up the suction nozzle. Subsequently, the drive motor 103 drives the rotating rod 104 to rotate, so that the mounting base 107 can move up and down while rotating. Multiple compression springs 203 elastically compress multiple clamping blocks 204. The movable rod 202 can slide along the inner wall of the square tube 201, so that the suction nozzle pre-rotation device can stably clamp various suction nozzle covers during the pre-rotation process of the suction nozzle cover. At the same time, the ball bearing 205 can rotate along the clamping block 204 to reduce the friction between the clamping block 204 and the suction nozzle, so that the suction nozzle pre-rotation device can pre-rotate suction nozzle covers of various specifications, thus expanding the applicability of the suction nozzle cover pre-rotation device.

[0037] Example 2: Figure 1-5 As shown, a nozzle pre-rotation device is disclosed. A support platform 210 is bolted to one side of a frame 100. A support mechanism is located in the middle of the frame 100 to support the opening of the nozzle bag. The support mechanism includes a servo motor 301, which is bolted to the outside of the frame 100. A bidirectional lead screw 302 is bolted to the rotating end of the servo motor 301, driving the bidirectional lead screw 302 to rotate. Side plates 303 are connected to both sides of the bidirectional lead screw 302. The rotation of the bidirectional lead screw 302 causes the side plates 303 to move closer or further apart. A top rod 304 is welded to one end of each side plate 303. A pressure sensor 320 is bolted inside the top rod 304 to detect the clamping force of the top rod 304. A limit rod 300 is slidably connected to one end of each side plate 303. An arc-shaped clamping plate A305 is bolted to one side of the top rod 304. On the other side of 304, an arc-shaped clamping plate B306 is fixed by bolts. Arc-shaped clamping plates A305 and B306 cooperate to clamp and fix stand-up pouches of various sizes. Rubber pads 310 are adhered to the inner walls of both arc-shaped clamping plates A305 and B306 to prevent scratches on the bottle openings. Multiple drive rollers 401 are rotatably connected inside the frame 100. A conveyor belt 402 is rotatably connected to the outer side of each drive roller 401. One end of the roller 401 is fixed with a toothed pulley 410 by bolts. The outer side of the toothed pulley 410 is connected to a toothed belt 420. Under the transmission action of the toothed pulley 410 and the toothed belt 420, multiple drive rollers 401 rotate synchronously. Both sides of the conveyor belt 402 are fixed with retaining rings 403 by bolts. The retaining rings 403 prevent the stand-up pouches from slipping off the conveyor belt 402. Multiple partitions 404 are evenly pasted on the outer wall of the conveyor belt 402, and the multiple partitions 404 separate the multiple stand-up pouches.

[0038] In this embodiment, the servo motor 301 drives the bidirectional lead screw 302 to rotate. The rotation of the bidirectional lead screw 302 causes the side plates 303 to move closer or further apart. Under the detection of the clamping force of the top rod 304 by the pressure sensor 320, the arc-shaped clamping plate A305 and the arc-shaped clamping plate B306 cooperate to clamp and fix various sizes of stand-up pouches. At the same time, the conveyor belt 402 drives multiple stand-up pouches forward in sequence, thereby replacing the manual hand-held operation and automatically supporting the stand-up pouches. This ensures the safety of the nozzle pre-rotation and improves the automation level of the nozzle pre-rotation device.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
