Description

Technical Field

[0001] This utility model relates to the field of cushioning bag technology, specifically to a cushioning bag film air column forming mechanism. Background Technology

[0002] In the field of packaging technology, air column cushioning bags are commonly used to package objects. Air column bags are prepared by processing and inflating an air-filled film. The film is held and laid flat by a clamping device for inflation, thus producing the air column bag. The air column cushioning bag winding device is designed to facilitate the storage and transportation of these bags. Currently, existing air column cushioning bags require winding via a winding drum after forming for convenient transportation.

[0003] To facilitate the disassembly and installation of the take-up drum, publication number CN220334258 U discloses a film winding device for a cushioning bag air column forming machine. This patent, including this utility model, discloses a film winding device for a cushioning bag air column forming machine, including a take-up drum. The take-up drum has symmetrically provided guard plates at both ends. Square slots are opened in both ends of the take-up drum. Square insert rods that are adapted to the square slots are symmetrically provided at both ends of the take-up drum. This patent uses a first motor to rotate a first sliding rod, which drives the square insert rods on both sides to disengage from the square slots on both sides of the take-up drum to achieve convenient disassembly.

[0004] However, after the square inserts on both sides of the above-mentioned patent disengage from the square slots, the take-up drum will fall directly, which is inconvenient for the staff to replace the take-up drum. In addition, the lifting device also moves to both sides, causing the clamping cylinder above the take-up drum to detach from the connecting rod. Therefore, in the above-mentioned patent, the take-up drum and the clamping cylinder are easy to fall off during the take-up drum replacement, which increases the difficulty of replacing the take-up drum.

[0005] The purpose of this invention is to provide a buffer bag film air column forming mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a buffer bag film air column forming mechanism, including a base, a sliding groove on the base, a bidirectional lead screw inside the sliding groove, a motor fixedly mounted on the side of the base, a slider inside the base, the surface of the slider being fixedly connected to a fixed plate, the side of the fixed plate being rotatably connected to one end of a rotating shaft, one end of the rotating shaft being fixedly connected to a square rod, a take-up drum on the base, the outer side of the take-up drum being fixedly connected to a baffle, both ends of the take-up drum being fixedly connected to a fixed cylinder, a square groove inside the fixed cylinder, a mating groove outside the fixed cylinder, the upper surface of the base being fixedly connected to a support plate, an arc-shaped groove on the top of the support plate, the top surface of the fixed plate being fixedly connected to a bracket, a movable plate inside the bracket, one end of the movable plate being rotatably connected to a connecting rod, one end of the connecting rod being fixedly connected to a cross plate, a connecting rod on the top of the movable plate, a pressing cylinder outside the cross plate, and a cross groove inside the spring.

[0007] Preferably, the inside of the groove is slidably connected to the outside of the slider, and the slider is symmetrically distributed inside the groove.

[0008] Preferably, one end of the bidirectional lead screw is rotatably connected to the inner wall of the slide groove, and the other end of the bidirectional lead screw is fixedly connected to the output end of the motor. Opposite threads are provided on both sides of the bidirectional lead screw, and the sliders are symmetrically distributed on both sides of the slider. The side of the slider is connected to the outer thread of the bidirectional lead screw through a threaded hole.

[0009] Preferably, a second motor is fixedly installed on the side of the fixing plate, one end of the rotating shaft is fixedly connected to the output end of the second motor, the other end of the rotating shaft is fixedly connected to a square rod, and the square rod is movably inserted into the square groove.

[0010] Preferably, steel balls are arranged inside the arc-shaped groove, and the fixed cylinder is connected to the arc-shaped groove through a mating groove.

[0011] Preferably, the bracket is fixedly connected to one end of the guide rod, the movable plate is slidably connected to the outside of the guide rod through a circular through hole, and the spring is sleeved on the outside of the guide rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses a two-way lead screw, slider, fixing plate, square rod, fixing cylinder, mating groove and support plate to place the fixing cylinders at both ends of the winding drum on the support plate, and connects the mating groove with the inside of the arc groove so that the steel column in the arc groove is located inside the mating groove, which limits the horizontal direction of the winding drum. The support plate supports and fixes the winding drum, avoiding the situation where the square rod disengages from the square groove when the fixing plates on both sides move, thus effectively reducing the difficulty of replacing the winding drum.

[0014] 2. This utility model also utilizes a bracket, a movable plate, a connecting rod, a cross plate, a spring, and a pressing cylinder. When the fixed plate moves to both sides, the movable plate moves synchronously, causing the connecting rod to drive the cross plate to slide inside the cross groove. This avoids interference between the horizontal movement of the pressing cylinder and the fixed plate, improving the efficiency of the operator in changing the winding drum. At the same time, the spring pushes the movable plate to ensure that the pressing roller always presses the buffer belt tightly, preventing the buffer belt from being blocked due to changes in thickness during winding.

[0022] Please see Figure 1-5This utility model provides a technical solution: a buffer bag film air column forming mechanism, including a base 1, a sliding groove 2 on the base 1, the inner wall of the sliding groove 2 being rotatably connected to one end of a bidirectional lead screw 3, the side of the base 1 being fixedly connected to a motor 4 by bolts, the base 1 being slidably connected to a slider 5, the surface of the slider 5 being welded and fixed to a fixing plate 6, the side of the fixing plate 6 being rotatably connected to one end of a rotating shaft 7, one end of the rotating shaft 7 being welded and fixed to a square rod 8, a take-up drum 9 being provided on the base 1, the outer side of the take-up drum 9 being welded and fixed to a baffle 10, and both ends of the take-up drum 9 being connected to the fixing drum 1. 1. Welding and fixing: A square groove 12 is formed inside the fixing cylinder 11, and a mating groove 13 is formed on the outside of the fixing cylinder 11. The upper surface of the base 1 is welded and fixed to the support plate 14. An arc-shaped groove 15 is formed on the top of the support plate 14. The top surface of the fixing plate 6 is welded and fixed to the bracket 16. A movable plate 17 is set on the bracket 16. One end of the movable plate 17 is rotatably connected to the connecting rod 18. One end of the connecting rod 18 is welded and fixed to the cross plate 19. A connecting rod 18 is set on the top of the movable plate 17. A clamping cylinder 21 is set on the outside of the cross plate 19. A cross groove 22 is formed inside the spring 20.

[0023] The slide groove 2 is slidably connected to the outer side of the slider 5. The sliders 5 are symmetrically distributed inside the slide groove 2. One end of the bidirectional lead screw 3 is rotatably connected to the inner wall of the slide groove 2, and the other end of the bidirectional lead screw 3 is welded and fixed to the output end of the motor 4. Opposite threads are provided on both sides of the bidirectional lead screw 3. The sliders 5 are symmetrically distributed on both sides of the slider 5. The sides of the sliders 5 are threadedly connected to the outer side of the bidirectional lead screw 3 through threaded holes. The motor 4 causes the bidirectional lead screw 3 to rotate, thereby causing the sliders 5 on both sides to move towards each other inside the slide groove 2. The fixing plate 6 pushes the square rod 8 into the square groove 12, so that the winding drum 9 is fixed on the support plate 14, which can realize convenient disassembly and replacement of the winding drum 9, effectively reducing the workload of the workers.

[0024] A second motor is fixedly mounted on the side of the fixed plate 6. One end of the rotating shaft 7 is welded and fixed to the output end of the second motor, and the other end of the rotating shaft 7 is welded and fixed to the square rod 8. The second motor causes the rotating shaft 7 and the square rod 8 to drive the winding drum 9 to rotate, thereby achieving the winding effect.

[0025] The square rod 8 is movably inserted into the square groove 12. A steel ball is placed inside the arc-shaped groove 15. The fixed cylinder 11 is connected to the arc-shaped groove 15 via a mating groove 13. The bracket 16 is welded and fixed to one end of the guide rod. The movable plate 17 is slidably connected to the outside of the guide rod through a circular through-hole. The spring 20 is sleeved on the outside of the guide rod.

[0026] Working principle: When installing the take-up drum 9, place it on the support plate 14 and engage the mating groove 13 with the arc-shaped groove 15. Simultaneously, ensure the steel column inside the arc-shaped groove 15 is located inside the mating groove 13. The horizontal movement of the take-up drum 9 is limited by the steel ball and the mating groove 13. Then, the motor 4 rotates the bidirectional lead screw 3, causing the sliders 5 on both sides to move towards each other inside the sliding groove 2. The fixing plate 6 pushes the square rod 8 into the square groove 12, thus fixing the take-up drum 9 to the support plate. On the support plate 14, the motor 2 on one side of the fixed plate 6 causes the take-up drum 9 to rotate. The clamping cylinder 21 presses the buffer belt onto the surface of the take-up drum 9. As the thickness of the buffer belt increases, the clamping cylinder 21 and the moving plate 17 move upward and squeeze the spring 20. When disassembling and replacing the take-up drum 9, the motor 1 4 causes the fixed plate 6 to move to both sides until the square rod 8 disengages from the inside of the square groove 12. Then, the take-up drum 9 is lifted upward so that the mating groove 13 disengages from the arc groove 15, thus completing the disassembly of the take-up drum 9.
