Description

Technical Field

[0001] This application relates to the technical field of the feeding device of a packaging machine, and more specifically, to a feeding device for a liquid sauce packaging machine. Background Art

[0002] A liquid sauce packaging machine is composed of a packaging machine, a liquid sauce storage tank, a sealing mechanism, a packaging bag guiding and conveying system, etc. The liquid sauce storage tank generally adopts a feeding structure with a feeding pipe of a filling tube type, and cooperates with a continuous feeding driving device to realize the intermittent filling and feeding of liquid sauce, so as to cooperate with the intermittent sealing to realize the packaging work of packaging bags one by one. However, since a large number of granular objects are often mixed in the liquid sauce and the fluidity is general, it will cause uneven feeding amount of the packaging bag. During the sealing process of the packaging bag, a small section of liquid dripping sauce will finally form at the end of the feeding pipe. Because the bottom opening of the packaging bag has been sealed, the packaging bag will become deflated. This part of the liquid dripping sauce will flow along the inner wall of the packaging bag to the next sealing position, resulting in the phenomenon of liquid sauce inside the sealed packaging bag. In view of this, we propose a feeding device for a liquid sauce packaging machine. Content of the Utility Model

Detailed Description of the Invention

[0019] The present application will be further described in detail below with reference to the accompanying drawings of the specification.

[0020] Refer to Figures 1 to 4, an embodiment of the present application provides a feeding device for a liquid sauce packaging machine, comprising: a T-shaped seat 1, on which an electric cylinder 3 is fixedly installed by threading, a F-shaped frame 2 is fixedly arranged on the T-shaped seat 1, two clamping sleeves 21 are fixedly arranged on the F-shaped frame 2, and a T-shaped receiving pipe 4 is fixedly installed through the clamping sleeves 21. The T-shaped receiving pipe 4 is threadedly connected to the discharge pipe of the liquid sauce storage tank. A ball valve 44 and a metering column 43 are rotatably installed in the T-shaped receiving pipe 4. The ball valve 44 and the metering column 43 are fixedly connected. The metering column 43 is fixedly connected with a first rotating arm 432. The piston rod of the electric cylinder 3 is connected with a metering feeding mechanism 5. The piston rod of the electric cylinder 3 extends and retracts, and drives the first rotating arm 432 through the metering feeding mechanism 5. The piston rod of the electric cylinder 3 is movably inserted into the T-shaped receiving pipe 4 and fixedly connected with a push column 31. The T-shaped receiving pipe 4 is threadedly sleeved with a hose 6. The hose 6 is threadedly connected with an L-shaped pipe 7. An air-blowing assembly 8 is fixedly arranged on the L-shaped pipe 7. A packaging tape guiding pipe 9 is arranged outside the L-shaped pipe 7.

[0021] By adopting the above technical solution, the liquid sauce feeding device is installed on the packaging machine for use. The T-shaped seat 1 is fixedly installed on the packaging machine body by threading and is arranged at the bottom of the liquid sauce storage tank. The T-shaped receiving pipe 4 is communicated with the discharge pipe of the liquid sauce storage tank. The packaging tape is sleeved outside the packaging tape guiding pipe 9. The sauce in the storage tank is quantitatively flowed into the metering column 43 by intermittent conveying of the bottom and side packaging mechanisms. When the piston rod of the electric cylinder 3 extends, the first rotating arm 432 can be driven to move through the metering feeding mechanism 5, so that the metering column 43 and the ball valve 44 rotate 90°, so that the metering column 43 can be communicated with the hose 6 through the ball valve 44. At the same time, the piston rod of the electric cylinder 3 forces the push column 31 to move along the T-shaped receiving pipe 4, so that the liquid sauce is forcibly extruded into the hose 6 and falls into a section of packaging bag for bottom and side packaging through the L-shaped pipe 7. And the air-blowing assembly 8 can blow nitrogen into this section of packaging bag, so that this section of packaging bag can be inflated, so that the liquid sauce finally dripping from the bottom port of the L-shaped pipe 7 will not drip on the inner wall of the packaging bag, avoiding the liquid sauce flowing along the inner wall of the packaging bag to the next packaging port. By repeatedly extending and retracting the piston rod of the electric cylinder 3, the metering sauce feeding operation can be realized.

[0022] Referring to Figure 1 and Figure 2 , a first screw sleeve 41 and a second screw sleeve 45 are fixedly arranged on the T-shaped receiving pipe 4. The T-shaped receiving pipe 4 is threadedly sleeved with the discharge pipe of the liquid sauce storage tank through the first screw sleeve 41. A nut 61 is rotatably arranged at both ends of the hose 6. The T-shaped receiving pipe 4 is threadedly sleeved with a nut 61 adjacent to the hose 6 through the second screw sleeve 45.

[0023] By adopting the above technical solution, the T-shaped material receiving pipe 4 can be threadedly connected to the discharge pipe of the liquid sauce storage tank and the hose 6 through the first screw sleeve 41 and the second screw sleeve 45 respectively. The hose 6 is provided to facilitate the adjustment of the installation height of the L-shaped pipe 7, so that the liquid sauce can flow smoothly.

[0024] Refer to Figure 2 and Figure 4 , both ends of the L-shaped pipe 7 are fixedly provided with a third screw sleeve 71 and a tapered head 72 respectively, and the third screw sleeve 71 is threadedly connected to the nut 61 adjacent to the hose 6.

[0025] By adopting the above technical solution, the push column 31 moves along the T-shaped material receiving pipe 4, can squeeze the liquid sauce at the ball valve 44, flows through the hose 6 into the L-shaped pipe 7, and is quickly extruded through the tapered head 72.

[0026] Refer to Figure 2 and Figure 3 , an arc-shaped groove 42 is formed on the T-shaped material receiving pipe 4, the first rotating arm 432 rotates along the arc-shaped groove 42, a material metering cavity 433 is arranged inside the metering column 43 and is communicated with the ball valve 44, and two sealing rings 431 are hermetically sleeved on the metering column 43 inside the T-shaped material receiving pipe 4 and are respectively arranged at the upper and lower parts of the arc-shaped groove 42.

[0027] By adopting the above technical solution, the first rotating arm 432 rotates along the arc-shaped groove 42 formed on the T-shaped material receiving pipe 4, so that the metering column 43 can rotate by 90°, thereby enabling the ball valve 44 to achieve the purpose of opening and closing. The metering column 43 can achieve the purpose of being hermetically sleeved and connected with the T-shaped material receiving pipe 4 by arranging two sealing rings 431.

[0028] Refer to Figure 1 and Figure 2 , the metering feeding mechanism 5 includes a cross guide rail 51, the cross guide rail 51 is fixedly connected to the T-shaped seat 1, a carriage 53 is slidably mounted on the cross guide rail 51, a return spring 52 is fixedly connected between the carriage 53 and the cross guide rail 51, the bottom end of the carriage 53 is fixedly sleeved with the piston rod of the electric cylinder 3, and the upper end of the carriage 53 is rotatably connected to a second rotating arm 54 through a shaft, and the second rotating arm 54 is rotatably connected to the first rotating arm 432 through a shaft.

[0029] By adopting the above technical solution, when the piston rod of the electric cylinder 3 expands and contracts, it can drive the carriage 53 to slide along the cross guide rail 51 and use the return spring 52 for buffering. The first rotating arm 432 and the second rotating arm 54 are connected into a connecting rod structure, so that the carriage 53 can drive the metering column 43 to rotate.

[0030] Refer to Figure 2 and Figure 4, the air inflation assembly 8 includes an air inlet pipe 81 which is connected to a nitrogen tank through an air pump. The air inlet pipe 81 is fixedly installed outside the L-shaped pipe 7 and is fixedly connected to an annular pipe 82. The annular pipe 82 is sleeved outside the conical head 72, and a plurality of air holes 821 are evenly formed in the annular pipe 82 along the circumference.

[0031] By adopting the above technical solution, the air pump extracts nitrogen from the nitrogen tank, transports it to the annular pipe 82 through the air inlet pipe 81, and transports it into the packaging bag through the plurality of annularly arranged air holes 821, forcing the packaging bag to bulge, so as to prevent the liquid sauce finally dripping from the bottom port of the L-shaped pipe 7 from dripping along the inner wall of the packaging bag to the next sealing position.

[0032] Working principle: The liquid sauce feeding device is installed on a packaging machine. By threadedly fixing the T-shaped seat 1 on the body of the packaging machine and setting it at the bottom of the liquid sauce storage tank, it is connected to the discharge pipe of the liquid sauce storage tank through the T-shaped receiving pipe 4. The packaging tape is sleeved outside the packaging tape guiding pipe 9 and is intermittently transported by the bottom and side sealing mechanisms. The sauce in the storage tank flows into the quantitative column 43 quantitatively. The piston rod of the electric cylinder 3 extends, and the first swing arm 432 can be driven to move through the quantitative feeding mechanism 5, so that the quantitative column 43 and the ball valve 44 rotate 90°, so that the quantitative column 43 can be connected to the hose 6 through the ball valve 44. At the same time, the piston rod of the electric cylinder 3 forces the push column 31 to move along the T-shaped receiving pipe 4, so that the liquid sauce is forcibly squeezed into the hose 6 and falls into a section of the packaging bag sealed at the bottom and side through the L-shaped pipe 7. The air inflation assembly 8 can inflate nitrogen into this section of the packaging bag to make this section of the packaging bag bulge. The air pump extracts nitrogen from the nitrogen tank, transports it to the annular pipe 82 through the air inlet pipe 81, and transports it into the packaging bag through the plurality of annularly arranged air holes 821, forcing the packaging bag to bulge, so as to prevent the liquid sauce finally dripping from the bottom port of the L-shaped pipe 7 from dripping along the inner wall of the packaging bag to the next sealing position. By repeatedly extending and retracting the piston rod of the electric cylinder 3, the operation of quantitatively feeding the sauce can be realized.
