Abstract
Description
Technical Field
[0001] This utility model relates to the field of manufacturing technology, specifically to a lifting airbag mechanism. Background Technology
[0002] In the field of automated processing technology, cans are divided into upper and lower cans, mainly used for shrinking and shaping folded airbags. In the workflow of automatic can-opening equipment, the folded airbag is first transferred to the lower can for can-closing. Then, the can is sent to an oven for heating, cooling and shaping. After shaping, it flows out of the oven and is placed on the can-opening equipment for automatic opening. Then, the airbag lifting mechanism lifts the shaped airbag out of the lower can. Finally, the transfer mechanism removes the shaped airbag and places it on the conveyor belt to exit the equipment, where it is manually removed for subsequent processes.
[0003] However, the lifting stroke of existing ordinary cylinders is limited by the length of the cylinder. Long strokes require the use of large-size cylinders, which takes up space and increases costs. Although existing synchronous belt drive mechanisms can amplify the stroke, they usually require an additional power source and have a complex structure. Summary of the Invention
[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a lifting airbag mechanism that doubles the stroke of the lifting unit through a stroke amplification unit.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting airbag mechanism, comprising a fixed base, a stroke amplification unit, a lifting unit, and a driving component; the stroke amplification unit includes a fixed plate slidably disposed on the fixed base, two synchronous pulleys rotatably disposed on the fixed plate, a synchronous belt sleeved on the two synchronous pulleys, and a fixed arm fixedly disposed on the synchronous belt; the two synchronous pulleys on the fixed plate are spaced apart along the sliding direction of the fixed plate, so that the synchronous belt between the two synchronous pulleys is parallel to the sliding direction of the fixed plate; the end of the fixed arm away from the synchronous belt is fixedly disposed on the fixed base; the lifting unit is fixedly disposed on the synchronous belt, and the lifting unit and the fixed arm are respectively connected to the two parallel sides of the synchronous belt; the driving component is fixedly disposed on the fixed base for driving the fixed plate to slide on the fixed base.
[0006] In some embodiments, the lifting unit is slidably disposed on the fixed plate, and the sliding direction of the lifting unit is the same as the sliding direction of the fixed plate on the fixed base.
[0007] In some embodiments, the distance between the two synchronizing pulleys is not less than the sliding stroke of the fixed plate on the fixed base.
[0008] In some embodiments, the one closer to the working position of the fixed plate among the two synchronous pulleys is the first synchronous pulley, and the other is the second synchronous pulley. The fixed arm is connected to the side of the synchronous belt near the first synchronous pulley, and the lifting unit is connected to the side of the synchronous belt near the second synchronous pulley.
[0009] In some embodiments, at least one of the two synchronous pulleys is movably mounted on a fixed plate, and the direction of movement is consistent with the sliding direction of the fixed plate, so that the distance between the two synchronous pulleys is adjustable.
[0010] In some embodiments, the mounting base includes a mounting plate for mounting the mounting plate and the driving component, a reinforcing plate fixed to one end of the mounting plate, and a triangular reinforcing brace connecting the mounting plate and the reinforcing plate.

[0014] In some embodiments, the drive component includes a cylinder fixed to a mounting base, the piston rod of the cylinder being fixedly connected to a mounting plate.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: the fixed plate is moved by the driving component, and the lifting unit moves synchronously with the fixed plate to achieve first-order movement. The fixed plate is equipped with a synchronous belt through two synchronous wheels. One side of the synchronous belt is connected to the fixed seat through a fixed arm. The lifting mechanism is fixed on the other side of the synchronous belt. During the movement of the fixed plate, relative displacement occurs with the fixed arm. The fixed arm drives the synchronous belt to rotate, thereby causing the lifting mechanism to produce second-order movement. This amplifies the stroke of the driving component, improves the working efficiency and lifting height of the lifting airbag mechanism. At the same time, the mechanism has a compact structure, low manufacturing cost, and high practicality and reliability.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4This utility model provides a technical solution: a lifting airbag mechanism, including a fixed base 1, a stroke amplification unit 2, a lifting unit 3, and a driving component 4; the stroke amplification unit 2 includes a fixed plate 21 slidably disposed on the fixed base 1, two synchronous pulleys 22 rotatably disposed on the fixed plate 21, a synchronous belt 23 sleeved on the two synchronous pulleys 22, and a fixed arm 24 fixed on the synchronous belt 23. The two synchronous pulleys 22 on the fixed plate 21 are spaced apart along the sliding direction of the fixed plate 21, so that the synchronous belt 23 between the two synchronous pulleys 22 is parallel to the sliding direction of the fixed plate 21. The end of the fixed arm 24 away from the synchronous belt 23 is fixed to the fixed base 1; the lifting unit 3 is fixed on the synchronous belt 23, and the lifting unit 3 and the fixed arm 24 are respectively connected to the two parallel sides of the synchronous belt 23; the driving component 4 is fixed on the fixed base 1 for driving the fixed plate 21 to slide on the fixed base 1;
[0024] During operation, the driving component 4 drives the fixed plate 21 to slide on the fixed base 1. When the fixed base 1 slides, it drives the two synchronous pulleys 22, the synchronous belt 23, and the lifting unit 3 to move synchronously, thereby realizing the first-order movement of the lifting unit 3. The stroke of the first-order movement is the movement stroke of the driving component 4 driving the fixed plate 21. When the fixed plate 21 drives the synchronous belt 23 and the synchronous pulleys 22 to move as a whole, the fixed arm 24 is fixedly set on the fixed base 1, so the fixed arm 24 does not move with the fixed plate 21. When the fixed plate 21 moves, the fixed arm 24 will form a relative displacement with the synchronous belt 23, the synchronous pulleys 22, and the lifting unit 3. Since the fixed arm 24 is fixedly connected to the synchronous belt 23, when the fixed plate 21 drives the synchronous pulleys 22 and the synchronous belt 23 to move, the fixed arm 24 will not move with the fixed plate 21. When the timing belt 23 is connected to the fixed arm 24, it remains relatively stationary with respect to the fixed arm 24. At this time, the timing belt 23 will rotate on the timing pulley 22, and the lifting unit 3 fixed on the other side of the timing belt 23 will undergo a second-order movement. The stroke of the second-order movement is also the stroke of the fixed plate 21. That is to say, when the driving component 4 drives the fixed plate 21 to move, the lifting unit 3 will move twice the stroke of the fixed plate 21 in the same direction, thereby amplifying the stroke of the lifting unit 3. The driving stroke of the driving component 4 is doubled through the relative displacement between the fixed arm 24 and the fixed plate 21, which improves the working efficiency and lifting height of the lifting airbag mechanism. At the same time, the mechanism has a compact structure, low manufacturing cost, and high practicality and reliability.
[0025] like Figures 1-3As shown, when the synchronous belt 23 is sleeved on the two synchronous pulleys 22, the two sides of the synchronous belt 23 between the two synchronous pulleys 22 are parallel to each other. Since the two synchronous pulleys 22 are spaced apart along the sliding direction of the fixed plate 21, the length direction of the parallel sides of the synchronous belt 23 is consistent with the sliding direction of the fixed plate 21. Therefore, when the lifting unit 3 is driven to move in a second order by the rotation of the synchronous belt 23, the movement direction of the lifting unit 3 is consistent with the movement direction of the fixed plate 21 when the rotation of the synchronous belt 23 drives the lifting unit 3 to move. This allows the first order movement and the second order movement of the lifting unit 3 to be directly superimposed, thereby doubling the driving stroke of the driving component 4 on the lifting unit 3.
[0026] like Figures 1-3 As shown, in this example, the fixed plate 21 is vertically slidably mounted on the fixed base 1. The driving component 4 is used to drive the fixed plate 21 to rise and fall. When the driving component 4 drives the fixed plate 21 to rise, the fixed plate 21 drives the two synchronous pulleys 22, the synchronous belt 23 and the lifting unit 3 to rise. At this time, the fixed arm 24 slowly approaches the synchronous pulley 22 located below, causing the synchronous belt 23 on the left side of the synchronous pulley 22 to move downward, while the synchronous belt 23 on the right side of the synchronous pulley 22 moves upward, thereby driving the lifting unit 3 to perform a second-order movement.
[0027] like Figures 1-4 As shown, the lifting unit 3 is further slidably mounted on the fixed plate 21, and the sliding direction of the lifting unit 3 is the same as the sliding direction of the fixed plate 21 on the fixed seat 1. When the synchronous belt 23 rotates and drives the lifting unit 3 to perform a second-order movement, the degree of freedom of the lifting unit 3 can be restricted by the sliding cooperation between the lifting unit 3 and the fixed plate 21, so that the lifting unit 3 can only move along its sliding direction, thereby improving the stability of the lifting unit 3 during the second-order movement.
[0028] Furthermore, the distance between the two synchronous pulleys 22 is not less than the sliding stroke of the fixed plate 21 on the fixed base 1. When the synchronous belt 23 rotates and drives the lifting unit 3 to move, the maximum stroke of the synchronous belt 23 driving the lifting unit 3 is the length of the synchronous belt 23 in the area between the synchronous pulleys 22. The larger the distance between the two synchronous pulleys 22, the longer the length of the synchronous belt 23 in the area between the two synchronous pulleys 22. When the distance between the two synchronous pulleys 22 is not less than the sliding stroke of the fixed plate 21 on the fixed base 1, the length of the synchronous belt 23 in the area between the two synchronous pulleys 22 is also greater than the sliding stroke of the fixed plate 21 on the fixed base 1. In other words, the synchronous belt 23 does not restrict the sliding stroke of the fixed plate 21.
[0029] Furthermore, of the two synchronous pulleys 22, the one closer to the working position of the fixed plate 21 is the first synchronous pulley 221, and the other is the second synchronous pulley 222. The fixed arm 24 is connected to the side of the synchronous belt 23 near the first synchronous pulley 221, and the lifting unit 3 is connected to the side of the synchronous belt 23 near the second synchronous pulley 222.
[0030] The working position of the fixed plate 21 refers to the position after the fixed plate 21 is driven to move by the driving component 4. In this example, the driving component 4 drives the fixed plate 21 to move upward to the working position. That is, the synchronous wheel 22 at the upper installation position is the first synchronous wheel 221, and the synchronous wheel 22 at the lower installation position is the second synchronous wheel 222. The fixed arm 24 is connected to the synchronous belt 23 near the first synchronous wheel 221. When the fixed plate 21 rises to the working position, the fixed arm 24 will move downward relative to the two synchronous wheels 22 and move closer to the second synchronous wheel 222. Connecting the fixed arm 24 to the position near the first synchronous wheel 221 allows the fixed arm 24 to make full use of the stroke of the synchronous belt 23 and prevents the fixed arm 24 from contacting the second synchronous wheel 222 too early. Similarly, the connection position of the lifting unit 3 and the synchronous belt 23 is close to the second synchronous wheel 222, so that the lifting unit 3 can make full use of the stroke of the synchronous belt 23 and prevents the lifting unit 3 from contacting the first synchronous wheel 221 too early.
[0031] Furthermore, at least one of the two synchronous pulleys 22 is movably mounted on the fixed plate 21, with the direction of movement being consistent with the sliding direction of the fixed plate 21, in order to tighten the synchronous belt 23 from the inside and prevent the synchronous belt 23 from slipping on the synchronous pulley 22.
[0032] Specifically, such as Figure 3 As shown, the first synchronous wheel 221 is mounted on the fixed plate 21 via an adjustable base. The adjustable base has an oblong hole. After the bolt passes through the oblong hole and the circular hole on the fixed plate 21, it cooperates with the nut to press the adjustable base. The length direction of the oblong hole is the same as the sliding direction of the fixed plate 21. The position of the adjustable base on the fixed plate 21 can be adjusted within the length range of the oblong hole, thereby realizing the adjustment of the distance between the first synchronous wheel 221 and the second synchronous wheel 222.
[0033] Specifically, such as Figure 2 As shown, the mounting base 1 includes a mounting plate 11 for mounting the mounting plate 21 and the driving component 4, a reinforcing plate 12 fixed to one end of the mounting plate 11, and a triangular reinforcing brace 13 connecting the mounting plate 11 and the reinforcing plate 12. The cooperation between the reinforcing plate 12 and the triangular reinforcing brace 13 increases the bending strength of the mounting plate 11 and ensures the safety of the entire device during use.
[0034] The mounting plate 11 has a first slide rail 14 fixed on one side for mounting the fixing plate 21. The fixing plate 21 has a first slider that matches the first slide rail 14 and is used for sliding cooperation with the first slide rail 14. The sliding cooperation between the fixing plate 21 and the mounting plate 11 is achieved through the cooperation between the first slider and the first slide rail 14. The fixing plate 21 has a second slide rail 25 fixed on one side for mounting the lifting unit 3. The lifting unit 3 has a second slider that matches the second slide rail 25 and is used for sliding cooperation with the second slide rail 25. The sliding cooperation between the lifting unit 3 and the fixing plate 21 is achieved through the cooperation between the second slider and the second slide rail 25. The first slide rail 14 and the second slide rail 25 are parallel to each other to ensure that the sliding direction of the fixing plate 21 and the lifting unit 3 is consistent.
[0035] Specifically, the end of the fixed arm 24 that is connected to the timing belt 23 is fixedly provided with a first clamping plate 26. The first clamping plate 26 is used to cooperate with the fixed arm 24 to clamp the timing belt 23, thereby realizing the fixed connection between the fixed arm 24 and the timing belt 23.
[0036] Specifically, the lifting unit 3 includes a mounting base 31 and a contact element 32 disposed on the mounting base 31. The mounting base 31 is slidably disposed on the fixing plate 21, and a second clamping plate 33 is fixedly disposed on the side of the mounting base 31 facing the synchronous belt 23. The second clamping plate 33 is used to cooperate with the mounting base 31 to clamp the synchronous belt 23.
[0037] The lifting unit 3 and the timing belt 23 are fixedly connected by pressing the timing belt 23 with the second pressing plate 33, and the contact member 32 is used to contact the workpiece that needs to be moved.
[0038] Specifically, such as Figure 3 As shown, the driving component 4 includes a cylinder, which is fixed on the fixed base 1. The piston rod of the cylinder is fixedly connected to the fixed plate 21, and the fixed plate 21 is driven to slide on the mounting plate 11 by the cylinder.
