Description

Technical Field

[0001] The utility model relates to the technical field of aerosol cans, in particular to an inflation positioning device. Background Art

[0002] Aerosol cans have the characteristics of convenient use, good airtightness and safe use, so they are widely used. Aerosol cans have a certain pressure and are generally made of iron or aluminum packaging. When inflating an aerosol can with an inflation device, it is necessary to position the aerosol can to prevent the aerosol can from moving during the inflation process, resulting in defective products.

[0003] According to the inflation mechanism of an aerosol filling machine disclosed in the patent with the publication number CN205907013U, the inflation mechanism of the aerosol filling machine includes a frame, a turntable, and an inflation device, and further includes a positioning device. The positioning device includes a sensor, a relay, and a positioning cylinder. The sensor is arranged on the frame and above the turntable, the positioning cylinder is arranged on the frame and directly opposite the upper middle part of the turntable, and the sensor, the relay, and the positioning cylinder are electrically connected in sequence. An adjustment groove is provided at the top of the frame, and the inflation device is movably installed in the adjustment groove through a mounting seat, and a locking piece is provided on the mounting seat.

[0004] Adopting the above scheme can press and position the aerosol can, prevent the aerosol can from moving during the inflation process, resulting in defective products, reduce the defective rate of the equipment, and improve the production efficiency. Although the above scheme can realize the positioning of the aerosol can, its system structure is complex. The system detects the position information of the aerosol can through a sensor, and then controls the expansion and contraction of the positioning cylinder through a relay, so as to realize the precise positioning and fixing of the aerosol can. It needs to rely on the coordinated work of multiple electrical devices such as sensors, relays, and positioning cylinders. Although this positioning method has a high positioning accuracy, due to the linkage of multiple electrical components, not only the system cost is high, but also the electrical components are easily damaged. If any one of the electrical components has a problem, the accurate positioning effect of the aerosol can cannot be achieved, and the positioning effect is not good. Therefore, we provide an inflation positioning device to solve the above problems. Content of the Utility Model

Detailed Embodiment

[0021] The principles and features of the present utility model will be described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0022] See Figures 1 to 4 , an inflation positioning device, including a workbench 1. The upper surface of the workbench 1 is fixedly connected with a support plate 2. The top of the support plate 2 is fixedly installed with a telescopic mechanism, and the telescopic mechanism is a telescopic cylinder 3. The telescopic end of the telescopic cylinder 3 is fixedly connected with a mounting plate 4. The bottom surface of the mounting plate 4 is fixedly connected with a group of extrusion rods 5. The bottom of the mounting plate 4 is fixedly installed with an inflation nozzle 6. The upper surface of the workbench 1 is fixedly connected with a bottom plate 7. A circular placement groove is provided at the center of the bottom plate 7, and the aerosol can is placed in the circular placement groove to achieve the limiting effect on the aerosol can.

[0023] One end of the extrusion rod 5 in contact with the slider 903 is spherical, which can reduce the friction with the slider 903. The spherical ball can also be replaced with a roller or a ball bearing. Moving wheels or ball bearings can also be installed below the slider 903, which can also reduce the friction when the slider 903 moves, making the slider 903 move more smoothly.

[0024] Above the bottom plate 7, there is a set of limiting mechanisms 8. The limiting mechanism 8 includes a fixing plate 801, and the bottom surface of the fixing plate 801 is fixedly connected to the upper surface of the bottom plate 7. A first guiding rod 802 is slidably connected inside the fixing plate 801. One end of the first guiding rod 802 is fixedly connected to a retaining piece 803. The retaining piece 803 can prevent the first guiding rod 802 from disengaging from the limit of the fixing plate 801. The other end of the first guiding rod 802 is fixedly connected to a first clamping block 804, and the bottom surface of the first clamping block 804 is slidably connected to the upper surface of the bottom plate 7. A first elastic member 805 is sleeved on the outer surface of the first guiding rod 802. The first elastic member 805 is made of a spring and has elasticity for telescopic rebound. One end of the first elastic member 805 is fixedly connected to the outer surface of the fixing plate 801, and one end of the first elastic member 805 is fixedly connected to the outer surface of the first clamping block 804. A layer of rubber pad is provided on the outer surface of the first clamping block 804, which will not damage the outer surface of the aerosol can when contacting it.

[0025] By pulling the retaining piece 803, the first guiding rod 802 and the first clamping block 804 can be driven to move accordingly. At the same time, the first clamping block 804 will compress the first elastic member 805, and then the first elastic member 805 will generate elastic deformation and store a certain amount of elastic potential energy. When the retaining piece 803 is released, the compressed first elastic member 805 will release the elastic potential energy, thereby pushing the first clamping block 804 to move in the reverse direction. At the same time, the first clamping block 804 will drive the first guiding rod 802 and the retaining piece 803 to move accordingly, thus realizing the rapid reset effect of the first guiding rod 802, the retaining piece 803 and the first clamping block 804.

[0026] Above the bottom plate 7, there is a set of positioning mechanisms 9. The positioning mechanism 9 includes a fixed block 901, and the bottom surface of the fixed block 901 is fixedly connected to the upper surface of the bottom plate 7. A second guiding rod 902 is slidably connected inside the fixed block 901. The other end of the second guiding rod 902 is fixedly connected to a second clamping block 904. An elastic member 905 is fixedly connected to the outer surface of the fixed block 901, and one end of the elastic member 905 away from the fixed block 901 is fixedly connected to the outer surface of the second clamping block 904. The elastic member 905 is made of a spring and has elasticity for telescopic rebound, which can realize the rapid reset effect of the second clamping block 904, the second guiding rod 902 and the slider 903. A circular placement groove is provided at the center of the bottom plate 7, and the aerosol can is placed in the circular placement groove to realize the limiting effect on the aerosol can.

[0027] When the extrusion rod 5 moves downward, it will contact the inclined surface of the slider 903 and extrude the slider 903 downward. As a result, the slider 903 will drive the second guide rod 902 and the second clamping block 904 to move closer to the aerosol can to be inflated. At the same time, the second clamping block 904 will stretch the second elastic member 905 until the second clamping block 904 clamps and fixes the aerosol can to be inflated placed at the center position of the bottom plate 7. When the extrusion rod 5 moves upward, at this time, the extrusion rod 5 will gradually release the pressure on the slider 903. At the same time, the stretched second elastic member 905 will drive the second clamping block 904, the second guide rod 902 and the slider 903 to move away from the aerosol can after inflation and reset, thereby releasing the positioning effect on the aerosol can after inflation.

[0028] Working principle: When the utility model is in use, the baffle 803 can be pulled outward, which can drive the first guide rod 802 and the first clamping block 804 to move accordingly. At the same time, the first clamping block 804 will compress the first elastic member 805, and then the first elastic member 805 will generate elastic deformation and store a certain amount of elastic potential energy. Then, the aerosol can to be inflated is placed in the placement groove at the center position of the bottom plate 7, and then the baffle 803 can be released. At this time, the compressed first elastic member 805 will release the elastic potential energy, thereby pushing the first clamping block 804, the first guide rod 802, and the baffle 803 to move in the reverse direction, so that the two first clamping blocks 804 can quickly and preliminarily position the aerosol can to be inflated. Then, the telescopic cylinder 3 is activated through an external controller. At this time, the telescopic end of the telescopic cylinder 3 will drive the mounting plate 4, the extrusion rod 5, and the inflation nozzle 6 to move downward. When the extrusion rod 5 moves downward, it will contact the inclined surface of the slider 903 and extrude the slider 903 downward. As a result, the slider 903 will drive the second guide rod 902 and the second clamping block 904 to move closer to the aerosol can to be inflated. At the same time, the second clamping block 904 will stretch the second elastic member 905 until the second clamping block 904 clamps and fixes the aerosol can to be inflated placed at the center position of the bottom plate 7. At the same time, the inflation nozzle 6 just combines with the aerosol can to be inflated below and performs the inflation operation. After the restart is completed, the telescopic cylinder 3 drives the mounting plate 4, the extrusion rod 5, and the inflation nozzle 6 to move upward again. At this time, the extrusion rod 5 will gradually release the pressure on the slider 903. At the same time, the stretched second elastic member 905 will drive the second clamping block 904, the second guide rod 902 and the slider 903 to move away from the aerosol can after inflation and reset, thereby releasing the positioning effect on the aerosol can after inflation. Through the mutual cooperation of the limiting mechanism 8, the extrusion rod 5 and the positioning mechanism 9, the rapid positioning effect on the aerosol can to be inflated can be realized. The overall cost is relatively low, the positioning effect is fast, and the positioning method is simple.

[0029] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
