Technical Field

[0001] The utility model belongs to the technical field of feeding tanks, and particularly relates to a negative pressure feeding tank. Background Art

[0002] In food processing, feeding tanks are often used as temporary storage equipment for materials. There are usually three ways to add materials to the feeding tank: first, open the cover and pour the materials into the tank by a robot; second, use a pump to transport the materials into the tank; third, use negative pressure to feed the materials into the tank.

[0003] In the prior art, the above three feeding methods are all single feeding methods, and the tank body that feeds by negative pressure is not provided with a cover or the cover cannot be opened. The feeding tank of the prior art cannot select a more suitable feeding method according to the material conveying speed requirements, placement position and other conditions. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0028] like Figure 1 to Figure 6 As shown, the negative pressure feeding tank of this embodiment includes a cylinder 1, a lower cone 2 is fixed to the lower part of the cylinder 1, a cover 3 is covered on the upper part of the cylinder 1, an opening and closing mechanism 4 is installed between the cylinder 1 and the lower cone 2, the output end of the opening and closing mechanism 4 is connected to the cover 3, a feed port pipe 11 and a vacuum port pipe 12 are provided on the cylinder 1, and a gate valve 5 is installed on the lower cone 2.

[0029] The opening and closing mechanism 4 of the utility model can drive the cover body 3 to open and close. When the cover body 3 is opened, the material can be poured by a robot; when the cover body 3 is closed, the material can be fed through the feed port pipe 11, and Haike opens the vacuum port pipe 12 at the same time to realize negative pressure feeding. During negative pressure feeding, the opening and closing mechanism 4 can make the cover body 3 and the cylinder body 1 reliably sealed and pressed to avoid leakage. When Gu Ya feeds, the feeding speed is faster, which is suitable for situations where fast feeding is required. The utility model can realize a variety of feeding methods including negative pressure feeding, which is convenient for users to choose the best feeding method according to the on-site material conditions.

[0030] Specifically, the opening and closing mechanism 4 includes a lower support plate 41 fixedly mounted on the lower cone 2, an opening and closing cylinder 42 is rotatably connected to the lower support plate 41, an upper support plate 43 is fixedly mounted on the cylinder 1, an active rod 44 and a rocker arm 45 are rotatably connected to the upper support plate 43, a connecting rod 46 is rotatably connected to the rocker arm 45, the other end of the connecting rod 46, the piston rod of the opening and closing cylinder 42 and the end of the active rod 44 away from the upper support plate 43 are rotatably connected through the same rotating shaft, and the other end of the rocker arm 45 is connected to the cover body 3. The shape of the rocker arm 45 is an arc. When the piston rod of the opening and closing cylinder 42 drives the connecting rod 46 to rotate, the connecting rod 46 pulls the rocker arm 45 to rotate, so that the rocker arm 45 pulls the cover body 3 to realize the opening and closing action of the cover body 3. The active rod 44 can limit the connecting rod 46 to ensure that the degree of freedom of the connecting rod 46 is 1, and to ensure accurate control of the opening and closing of the cover body 3.

[0031] It should be noted that when locking the cover 3, the cover 3 is closed, and the piston rod of the opening and closing cylinder 42 pushes the connecting rod 46 to a position where the rocker arm forms a self-locking state. The connecting line between the connection point between the upper support plate 43 and the rocker arm 45 and the connecting line between the connecting rod 46 and the rocker arm 45 is perpendicular to the connecting rod 46. At this time, if the cover 3 is to be opened, the thrust of the rocker arm 45 on the connecting rod 46 coincides with the arrangement direction of the connecting rod 46, so that the connecting rod 46 cannot rotate, and then the rocker arm 45 cannot rotate, forming a self-locking state, and preventing the cover 3 from being opened by mistake.

[0032] In order to facilitate the adjustment of the cover body 3, two lifting ears 31 are fixed on the cover body 3, a balancing shaft 32 is sleeved between the two lifting ears 31, a connecting column 33 is connected to the balancing shaft 32, the other end of the connecting column 33 is passed through the rocker arm 45, and the connecting column 33 is locked with the rocker arm 45 by an adjusting nut 34.

[0033] The lifting lug 31 is threadedly connected with a set screw 35, and the set screw 35 tightens the balancing shaft 32 from the upper side or the lower side. Set screws 35 are provided on both sides of the balancing shaft 32, so that by adjusting the two set screws 35, the horizontality of the balancing shaft 32 can be adjusted, and the horizontality of the cover body 3 can be adjusted accordingly to prevent the cover body 3 from tilting.

[0034] In order to ensure reliable sealing between the cover body 3 and the cylinder body 1, the upper opening of the cylinder body 1 is provided with a tank flange 6, the upper cross section of the tank flange 6 is triangular, and a sealing ring 7 is provided on the lower side of the cover body 3, the lower side of the sealing ring 7 has a triangular opening, and the sealing ring 7 is pressed tightly against the tank flange 6.
