Description
Technical Field
[0001] This utility model relates to the field of automotive urea production technology, specifically a filling machine for automotive urea solution production and processing. Background Technology
[0002] Automotive urea is a liquid used in SCR technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. During the production of automotive urea solution, a measured amount of urea granules and high-purity water are directly added to a mixing tank for mixing and stirring to obtain a qualified automotive urea solution.
[0003] For example, the utility model patent with publication number CN209721554U discloses a vehicle urea filling equipment, which relates to the field of liquid filling technology. It includes a vehicle urea storage tank, a support frame is vertically arranged at the lower rear end of the vehicle urea storage tank, a conveying hose is arranged below the urea storage tank, the lower end of the conveying hose is connected to the discharge pipe, a filling head is vertically arranged on the lower left side of the discharge pipe, a horizontal adjustment device is fixedly connected to the right end of the discharge pipe, a vertical adjustment component is arranged on the right side of the horizontal adjustment device, and the horizontal adjustment device is installed in front of the support frame through the vertical adjustment component. The utility model's support frame and filling base ensure stable fixation of the urea storage tank. The horizontal and vertical adjustment devices allow for adjustment of the discharge pipe position, ensuring the filling head accurately reaches the finished product tank to accommodate different tank sizes. The entire utility model has a simple structure, convenient, fast, efficient, and highly practical filling process. However, when liquid is present on the upper part of the filling base, empty bottles may shift during filling, causing misalignment of the filling position and interference between the bottle and the filling head, ultimately leading to instability in the entire filling process. Therefore, we propose a filling machine for automotive urea solution production and processing. Utility Model Content

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.
[0021] Please see Figures 1-4This utility model provides a technical solution: a filling machine for producing and processing automotive urea solution, including a filling base 1, a double limiting arc plate 5 fixedly installed at the middle of the upper end of the filling base 1, two sets of symmetrically arranged water permeable holes 2 opened at the upper end of the filling base 1, two symmetrically arranged sliding grooves 4 opened at the front end of the filling base 1, a filling mechanism 7 provided at the rear side of the upper end of the filling base 1, and a filling bottle limiting mechanism 6 provided on the filling base 1.

[0022] In this embodiment, the filling bottle limiting mechanism 6 includes a U-shaped plate 61, with moving grooves 62 on both sides of the U-shaped plate 61. A stepper motor 63 is fixedly installed at the middle of the front end of the U-shaped plate 61, and a rotating shaft 64 is fixedly installed at the output end of the stepper motor 63. A rotating gear 65 is fixedly installed at the rear end of the rotating shaft 64. Two moving racks 66 arranged centrally symmetrically are meshed at the outer end of the rotating gear 65. The outer end of each moving rack 66 is slidably connected to the moving groove 62. An L-shaped moving strip 67 is fixedly installed at the outer end of each moving rack 66. An outer limiting arc plate 69 is fixedly installed at the upper end of the L-shaped moving strip 67. The outer limiting arc plate 69 is located on the upper part of the filling base 1.
[0023] Specifically, when filling urea into the bottles, each bottle is placed on the filling base 1, with each bottle positioned above each set of permeable holes 2. Next, the stepper motor 63 is activated. The output of the stepper motor 63 drives the rotating shaft 64 to rotate, which in turn drives the rotating gear 65 to rotate counterclockwise. The rotating gear 65 then drives two centrally symmetrically arranged moving racks 66 to move closer together. Each moving rack 66 drives a slider 68 to slide within the groove 4. The slider 68 improves the stability of the moving racks 66 during movement. Each moving rack 66 also drives an L-shaped moving strip 67 and an outer limiting arc plate 69 to move. The two symmetrically arranged outer limiting arc plates 69 move closer together, and the two outer limiting arc plates 69, in conjunction with the double limiting arc plate 5, clamp and limit the two bottles.
[0024] In this embodiment, the filling mechanism 7 includes a vertical plate 71, a filling base 1 is fixedly installed at the lower end of the vertical plate 71, a filling device 710 is fixedly installed on the upper front side of the vertical plate 71, and two symmetrically arranged first electric push rods 72 are fixedly installed on the upper rear side of the filling base 1. Each first electric push rod 72 has an L-shaped upward moving plate 73 fixedly installed at its output end. A second electric push rod 74 is fixedly installed at the front end of the L-shaped upward moving plate 73.

A liquid storage bottle 77 is fixedly installed at the front end of the moving plate 76. A telescopic tube 78 is fixedly connected to the front end of the liquid storage bottle 77. The upper end of the telescopic tube 78 is fixedly connected to the filling device 710.
[0025] Specifically, the filling mechanism 7 can simultaneously fill two bottles, and the position of the filling head 79 can be adjusted to extend into the bottle mouth for filling, thus improving the accuracy of the filling process.
[0026] In this embodiment, two symmetrically arranged through grooves 3 are provided at the lower end of the filling base 1, and each through groove 3 is connected to a water-permeable hole 2.
[0027] Specifically, a through groove 3 is provided to allow liquid flowing through the permeable hole 2 to a position outside the filling base 1.
[0028] In this embodiment, the first electric push rod 72 is located on the front side of the vertical plate 71, and the filling head 79 is located at the lower middle part of the liquid storage bottle 77.
[0029] Specifically, the filling head 79 can be used to fill the bottles.
[0030] In this embodiment, each L-shaped moving bar 67 has a slide bar 68 fixedly installed at its rear end, and each slide bar 68 has a slide groove 4 slidably connected to its outer end.
[0031] Specifically, the L-shaped moving bar 67 drives the slider 68 to slide, and the slider 68 slides within the groove 4, which improves the stability of the L-shaped moving bar 67 during movement.
[0032] In this embodiment, a second protective pad 8 is fixedly installed on the outer end of the double limiting arc plate 5, and a first protective pad 610 is fixedly installed on the inner end of each outer limiting arc plate 69.
[0033] Specifically, the first protective pad 610 and the second anti-slip pad can reduce scratches on the outer end of the filling bottle.
[0034] Working principle: In use, first place two filling bottles on the filling base 1, then start the stepper motor 63. The output of the stepper motor 63 drives the rotating shaft 64 to rotate, which in turn drives the rotating gear 65 to rotate counterclockwise. At this time, the rotating gear 65 drives two centrally symmetrically arranged moving racks 66 to move closer to each other. Each moving rack 66 drives the slide bar 68 to slide in the slide groove 4. The slide bar 68 can improve the stability of the moving rack 66 during the movement. At this time, each moving rack 66 drives the L-shaped moving bar 67 and the outer limiting arc plate 69 to move. The two symmetrically arranged outer limiting arc plates 69 move closer to each other. The two outer limiting arc plates 69 cooperate with the double limiting arc plate 5 to clamp and limit the two filling bottles. Then, the filling mechanism 7 can be used to fill the bottles with urea.
