Description

Technical Field

[0001] The utility model relates to the technical field of packaging machines, in particular to a metering packaging machine. Background Art

[0002] A metering and packaging machine is a piece of equipment required by companies to package and pack products after production. Currently, when a metering and packaging machine unloads materials, the material enters the packaging container. Due to the height difference between the discharge end of the metering and packaging machine and the bottom of the packaging container, this can cause material splashing. This is especially true when packaging liquid products. When liquid splashes outside the packaging container, it directly affects the workshop environment.

[0003] Therefore, improvements are needed. Utility Model Content

[0051] The anti-splash structure 2 and the discharge structure 3 can be controlled by the lifting mechanism to move in opposite directions in cooperation with the rack 4 and the rack structure.

[0052] In this embodiment: the splash-proof structure 2 includes:

[0053] The first split body 21 is slidably mounted on the body 10;

[0054] The second split body 22 is hinged to the first split body 21 on one side via a hinge 22a, and is detachably connected to the first split body 21 on the other side via a connecting structure;

[0055] The cross-sectional shapes of the first body 21 and the second body 22 are both semi-circular. When the first body 21 and the second body 22 are connected, they form a splash-proof cavity that can cover the barrel.

[0056] In this embodiment, a slide rail 10 a is provided on the body 10 , and a slide groove 10 b adapted to the slide rail 10 a is provided on the first split body 21 .

[0057] In this embodiment: the lifting structure includes:

[0058] The screw shaft 60 is rotatably mounted on the body 10 and can be controlled by the motor 60a to rotate clockwise or counterclockwise.

[0059] The screw bearing seat 61 is cooperatively disposed on the screw shaft 60 and connected to the first split body 21 .

[0060] In this embodiment, reference Figure 3The machine body 10 is provided with a transmission chamber (the transmission chamber extends longitudinally) for the movement of the screw shaft 60, the screw shaft 60 (the screw shaft is arranged longitudinally) is arranged in the transmission chamber, the motor 60a is arranged on the base 11, and the main shaft of the motor 60a is connected to the screw shaft 60, thereby driving the screw shaft to rotate.

[0061] In this embodiment, the lifting structure is composed of two screw structures, and the screw bearing seats 61 of the two screw structures are both connected to the first split body.

[0062] In this embodiment: the discharge structure 3 includes:

[0063] The discharge body 30 is coaxially arranged with the anti-splash chamber;

[0064] A filter cavity 31 is formed in the discharge body 30;

[0065] The feed pipe 32 is provided at the top of the discharge body 30 and communicates with the top of the filter chamber 31. The feed pipe is connected to an external material pipe and is used to receive the material into the filter chamber;

[0066] The filter screen 33 is disposed in the filter chamber 31;

[0067] The discharge pipe 34 is provided at the bottom of the discharge body 30 and communicates with the filter cavity 31;

[0068] Wherein, the discharge pipe 34 is provided with a control valve.

[0069] In this embodiment, the control valve can be a solenoid valve, which includes a valve body 70 installed on the discharge pipe 34, an electromagnet 71 provided on the valve body 70, a valve cavity 72 formed on the valve body 70, and a piston shaft 74 slidingly connected to the valve cavity 72, a spring 75 is provided between the piston shaft and the valve cavity 72, one end of the piston shaft penetrates into the discharge pipe 34, and a closing body 76 is provided at one end of the piston shaft.

[0070] refer to Figure 1-4 , the principle of this embodiment is:

[0071] During packaging, the lifting mechanism controls the anti-splash structure to descend, and the discharge structure is controlled to rise through the rack structure and gear. Then, the second split body is opened, and the barrel-shaped container is placed on the base, and then the second split body is closed;

[0072] Subsequently, the lifting mechanism controls the anti-splash structure to rise and the discharge structure to descend, and the discharge body to enter the container. When the control valve is opened and the material is discharged, and the material enters the container, the lifting structure controls the anti-splash structure to descend again, and the discharge body to gradually rise, thereby completing the discharge work. After the container is loaded with material, the second split is opened and a new container is replaced.

[0073] In the above process of this embodiment, the discharge body can enter the container. Therefore, in the early stage of discharge, although the splash-proof structure is located above the container, the inner wall of the container itself can also prevent the material from splashing. When the discharge body gradually rises and leaves the container, the splash-proof structure descends, thereby covering the container. Therefore, in the later stage of discharge, the splash-proof structure can be used to prevent the material from splashing.

[0074] Example 2 is different from Example 1 in that:

[0075] like Figure 5 As shown, in this embodiment: the connection structure includes:

[0076] The base shaft is composed of a first shaft body 81 mounted on the first split body 21 and a second shaft body 82 mounted on the second split body 22, and the cross-sectional shapes of the first shaft body 81 and the second shaft body 82 are both semicircular;

[0077] The connecting ring 83 can be sleeved on the base shaft and fix the first shaft 81 and the second shaft 82;

[0078] Wherein, magnets are provided on the first shaft 81 and / or the second shaft 82 .

[0079] In this embodiment: the first shaft 81 and the second shaft 82 are provided with a stud 84 that can adapt to each other and is semi-cylindrical in shape, and the connecting ring 83 is a nut that can cooperate with the stud 83, that is, the first shaft and the second shaft are both semi-cylindrical, and when the two are in contact, a cylindrical stud is formed.

[0080] refer to Figure 5 , Figure 5 This is a side schematic diagram of the splash-proof structure of this embodiment. When the first split and the second split of this embodiment are fixed, the two can be closed and the first shaft body and the second shaft body can be brought close to each other through magnets. At this time, the first shaft body and the second shaft body are attached to each other and the semi-cylindrical stud forms a complete stud. Finally, the nut is screwed onto the stud to fix the first shaft body and the second shaft body, completing the fixation of the first split and the second split.

[0081] The purpose of providing the magnet in this embodiment is to facilitate the installation of the nut. That is to say, when the first shaft and the second shaft are close to each other, the two will be tightly attached due to the magnet, thereby facilitating the installation of the nut.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
