Description

Technical Field

[0001] The utility model relates to the technical field of protective devices, in particular to a protective device for a ball forming machine. Background Art

[0002] The pot-type granulator, also known as a ball-forming machine, works on the principle that the transmission device drives the granulation pot to rotate through the bridge device, and the axis of the granulation pot is at a specific angle to the horizontal plane; when the powder is added into the granulation pot through the feed port, water is sprayed into the granulation pot, and the wet powder gradually forms a ball core while rolling. The ball core with a wet surface gradually grows into a granule under continuous rolling, friction and collision. When the particle size reaches the requirement, it is unloaded through the discharge door.

[0003] The tank (granulation pot) of a common ball forming machine is placed in the air and exposed. It rotates at high speed. There are no relevant protective measures or protective devices during its rotation. When workers are not careful or operate improperly, it is easy to cause danger to workers. In addition, the tank itself has a certain risk of falling. Therefore, it is necessary to design a protective device for the ball forming machine. Utility Model Content

[0021] Embodiment

[0022] The following is further described in conjunction with specific embodiments. As shown in the attached Figure 1 - attached Figure 5 As shown, the pelletizer protection device of this embodiment includes an arc-shaped protective frame 21, a connecting plate 22 fixedly arranged on the lower side of the protective frame 21, and a support device arranged below the protective frame 21; the protective frame 21 is arranged on the lower side of the tank body 11 of the pelletizer 10; the support device includes a bottom plate 31 and a telescopic mechanism hinged on the bottom plate 31; the telescopic mechanism is hinged with the connecting plate 22, and the connecting plate 22 is hinged with the bottom plate 31 through a connecting piece. Specifically, when in use, the protective frame 21 and the support device are installed under the tank body 11 of the pelletizer 10, and the protective frame 21 is supported by the support device, and the protective frame 21 can prevent workers from contacting the tank body 11 of the pelletizer 10 when the pelletizer 10 is running, and can protect the safety of workers to a certain extent. When the pelletizer 10 is not running, the telescopic mechanism can be used to push the protective frame 21 to rotate upward around the hinge point of the connecting plate 22 and the connecting piece, and make part of the protective frame 21 contact the lower side of the tank body 11, playing a supporting role for the tank body 11 and preventing the tank body 11 from falling. Therefore, this device can not only protect the safety of workers when the pelletizer 10 is running, but also prevent it from falling when the pelletizer 10 is not running.

[0023] In this embodiment, a horizontally arranged first sleeve 23 and a second sleeve 24 are provided on the lower side of the connecting plate 22; the first sleeve 23 and the second sleeve 24 are parallel to each other; the telescopic mechanism is connected to the first sleeve 23, and the connecting piece is connected to the second sleeve 24. Specifically, the first sleeve 23 and the second sleeve 24 can play a role in supporting the protective frame 21, and the lengths of the first sleeve 23 and the second sleeve 24 are greater than the width of the connecting plate 22. Therefore, the force on the connecting plate 22 can be more balanced through the first sleeve 23 and the second sleeve 24, and it is less likely to tip over.

[0024] In the present embodiment, a first rotating shaft 32 is rotatably arranged inside a first sleeve 23, and one end of the telescopic mechanism away from the bottom plate 31 is connected to the first rotating shaft 32. There are a pair of telescopic mechanisms; both of the pair of telescopic mechanisms are hinged to the bottom plate 31, the pair of telescopic mechanisms are respectively arranged at both ends of the first rotating shaft 32, and the pair of telescopic mechanisms are respectively connected to both ends of the first rotating shaft 32. The telescopic mechanism includes an electric push rod; the cylinder body of the electric push rod is hinged to the bottom plate 31, and the telescopic rod of the electric push rod is connected to the first rotating shaft 32. Specifically, by pushing the first rotating shaft 32 with the electric push rod, the protective frame 21 can be rotated around the second sleeve 24 as the center until a part of the protective frame 21 contacts the tank body 11, achieving the supporting effect on the tank body 11.

[0025] In the present embodiment, it further includes a pair of support columns 35 vertically arranged at both ends of the first rotating shaft 32, and a screw rod 36 threadedly connected to the lower end of the support column 35; the upper side wall of the support column 35 is rotatably connected to the end of the first rotating shaft 32. A horizontally arranged backing plate 37 is provided at the lower end of the screw rod 36. Specifically, the upper side wall of the support column 35 is rotatably connected to the end of the first rotating shaft 32, so that no matter how the first rotating shaft 32 rotates, the support column 35 can maintain a vertical state. The function of the support column 35 is to prevent the electric push rod from suddenly losing the supporting force. The existence of the support column 35 makes the protective frame 21 not suddenly fall downwards. By screwing the screw rod 36, the backing plate 37 at the lower end of the screw rod 36 contacts the bottom plate 31, so that a stable supporting effect can be achieved, and the electric push rod does not need to bear too much force, which can avoid damage to the electric push rod. When it is necessary to rotate the protective frame 21 downwards, it is necessary to first screw the screw rod 36 to make the backing plate 37 rise a certain distance.

[0026] The connecting member in the present embodiment includes a second rotating shaft 33 rotatably arranged inside the second sleeve 24, and a pair of support plates 34 fixedly arranged on the bottom plate 31; the pair of support plates 34 are respectively connected to both ends of the second rotating shaft 33.

[0027] In summary, for the ball forming machine protection device of the present embodiment, when in use, the protective frame 21 and the supporting device are installed under the tank body 11 of the ball forming machine 10. The protective frame 21 is supported by the supporting device, and the protective frame 21 can prevent workers from contacting the tank body 11 of the ball forming machine 10 during the operation of the ball forming machine 10, which can protect the safety of workers to a certain extent. When the ball forming machine 10 is not operating, the telescopic mechanism can be used to push the protective frame 21 to rotate upwards at the hinge joint between the connecting plate 22 and the connecting member, and make a part of the protective frame 21 contact the lower side of the tank body 11, playing a supporting role for the tank body 11 and preventing the tank body 11 from falling. Therefore, this device can not only protect the safety of workers during the operation of the ball forming machine 10, but also prevent it from falling when the ball forming machine 10 is not operating.

[0028] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
