[0002] When producing products such as high-quality ice cream and Nurikin low-GI powders with small particle sizes and large density ratios in vermicelli packaging production, due to the small mesh number and large density ratio of the powder, and the fixed structure of the anti-leakage net (it cannot rotate with the rotation of the screw), during the production process, material blockage often occurs near the anti-leakage net of the screw.

[0003] Therefore, we propose a metering screw for a strip packing machine to solve the above problems. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a metering screw for a strip packing machine, in which the anti-leakage net rotates with the rotation of the screw body, thereby reducing the probability of material blockage of the anti-leakage net and effectively solving the problems in the background technique.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A metering screw for a strip packing machine includes a threaded sleeve, a screw body extending into the inner cavity of the threaded sleeve, a spiral blade integrally welded to the outer wall of the screw body, and a powder discharging cup installed on one side of the threaded sleeve. The spiral blade spirals outside the screw body, so as to realize the transportation of vermicelli through the rotation of the screw body and the spiral blade. A anti-leakage net is integrally connected to one side of the screw body close to the powder discharging cup. On the outer wall of the threaded sleeve close to the powder discharging cup, convex blocks are symmetrically welded. Rotating blocks are respectively rotatably connected to the two convex blocks. Thin screws are respectively coaxially connected to the two rotating blocks, and inserting blocks are respectively threadedly sleeved on the two thin screws;

[0007] A plate-shaped bracket is welded at a position between the two convex blocks in the inner cavity of the threaded sleeve. An installation groove is formed on the side of the bracket facing away from the powder discharging cup. A bearing seat is installed in the installation groove, and a screw body connecting block is fitted and installed in the bearing seat. The screw body connecting block is fixedly welded to one end of the screw body, so that one side of the screw body extending into the inner cavity of the threaded sleeve is kept stable under the action of the bracket and the bearing seat. Sockets are respectively formed on both sides of the screw body connecting block, and the two inserting blocks are respectively slidably inserted into the two sockets.

[0008] As a preferred implementation, side openings are respectively formed on the opposite sides of the two convex blocks, and the two rotating blocks are respectively installed in the two side openings; so that the two rotating blocks can be hidden in the side openings and thus protected.

[0009] As a preferred embodiment, internal hexagonal grooves are formed on the opposite sides of the two rotating blocks; thus, it is convenient for tools such as external internal hexagonal screwdrivers to extend into the internal hexagonal grooves, so that the rotating blocks can be rotated.

[0010] As a preferred embodiment, internal sliding grooves are formed on both sides inside the bracket, and the two thin screws are respectively located in the two internal sliding grooves and are rotatably connected to the inner walls of the internal sliding grooves; the internal sliding grooves and the sockets are sealed inside the bracket.

[0011] As a preferred embodiment, the two insertion blocks are respectively attached to the inner walls of the two internal sliding grooves; so that when the thin screws operate, the insertion blocks can be driven to slide in the internal sliding grooves.

[0012] In summary, the technical effects and advantages of the present utility model are as follows:

[0013] For this strip wrapping machine metering screw, since it includes a threaded sleeve, a screw rod body extending into the inner cavity of the threaded sleeve, a spiral blade integrally welded to the outer wall of the screw rod body, and a powder feeding cup installed on one side of the threaded sleeve, wherein the spiral blade spirals on the outside of the screw rod body, thus realizing the conveyance of vermicelli through the rotation of the screw rod body and the spiral blade. A leak-proof net is integrally connected to the side of the screw rod body close to the powder feeding cup, and the leak-proof net rotates as the screw rod body rotates, thereby reducing the probability of the leak-proof net being blocked by materials;

[0014] For this strip wrapping machine metering screw, by rotating the two rotating blocks to drive the two thin screws to operate, so that the two insertion blocks are driven to separate from the two sockets, the threaded sleeve can be taken out from the outside of the screw rod body, thus facilitating the replacement of the screw rod body, so as to replace it in time when the screw rod body is damaged, avoiding replacing the entire module and reducing the replacement cost.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Referring to Figures 1 - 3 , a metering screw of a strip packing machine includes a threaded sleeve 1, a screw main body 2 extending into the inner cavity of the threaded sleeve 1, a spiral blade 3 integrally welded to the outer wall of the screw main body 2, and a powder feeding cup 15 installed on one side of the threaded sleeve 1. The spiral blade 3 spirals around the outside of the screw main body 2, so as to realize the conveying of vermicelli by the rotation of the screw main body 2 and the spiral blade 3. A leakage prevention net is integrally connected to one side of the screw main body 2 close to the powder feeding cup 15. The leakage prevention net rotates with the rotation of the screw main body 2, so as to reduce the probability of the leakage prevention net being blocked by materials;

[0021] On the outer wall of the threaded sleeve 1 close to the powder feeding cup 15, convex blocks 4 are symmetrically welded. Rotating blocks 6 are respectively rotatably connected to the two convex blocks 4. Side openings 5 are formed on the opposite sides of the two convex blocks 4. The two rotating blocks 6 are respectively installed in the two side openings 5, so that the two rotating blocks 6 can be hidden in the side openings 5 and thus be protected. Inner hexagonal grooves 7 are formed on the opposite sides of the two rotating blocks 6, so as to facilitate the use of tools such as external inner hexagonal screwdrivers to extend into the inner hexagonal grooves 7, so that the rotating blocks 6 can be rotated. Thin screws 9 are respectively coaxially connected to the two rotating blocks 6, and insertion blocks 10 are respectively sleeved on the two thin screws 9 in a threaded manner;

[0022] A plate-shaped support 11 is welded at a position between the two convex blocks 4 in the inner cavity of the threaded sleeve 1. An installation groove is formed on the side of the support 11 facing away from the powder feeding cup 15. A bearing seat 12 is installed in the installation groove, and a screw main body connection block 13 is fitted and installed in the bearing seat 12. The screw main body connection block 13 is fixedly welded to one end of the screw main body 2, so that one side of the screw main body 2 extending into the inner cavity of the threaded sleeve 1 is kept stable under the action of the support 11 and the bearing seat 12. Socket openings 14 are respectively formed on both sides of the screw main body connection block 13. The two insertion blocks 10 are respectively slidably inserted into the two socket openings 14. Inner sliding grooves 8 are respectively formed on both sides inside the support 11. The two thin screws 9 are respectively located in the two inner sliding grooves 8 and are rotatably connected to the inner walls of the inner sliding grooves 8. The inner sliding grooves 8 and the socket openings 14 are sealed inside the support 11. The two insertion blocks 10 are respectively attached to the inner walls of the two inner sliding grooves 8, so that the thin screws 9 can drive the insertion blocks 10 to slide in the inner sliding grooves 8 when operating.

[0023] This strip-packing metering screw: During installation, the side of the screw body 2 facing away from the powder cup 15 is connected to an external motor. The motor is powered on to operate and drives the screw body 2 to rotate within the inner cavity of the threaded sleeve 1, so that the vermicelli material is input from the side of the threaded sleeve 1 facing away from the powder cup 15. The vermicelli material is gradually conveyed towards the side where the powder cup 15 is located under the action of the rotation of the spiral blade 3 within the inner cavity of the threaded sleeve 1. At the same time, it is cut into a specified shape under the action of the threads on the inner wall of the threaded sleeve 1 and the spiral blade 3, and finally vermicelli of a specified shape and thickness is output from the powder cup 15; if the screw body 2 or the spiral blade 3 is worn or damaged after long-term use, two hexagon screwdrivers can be inserted into the two hexagon slots 7 and rotated to drive the two rotating blocks 6, causing the two thin screws 9 to rotate accordingly, driving the two insertion blocks 10 to slide in opposite directions, thus releasing the limitation of the two insertion blocks 10 on the connection block 13 of the screw body. At this time, the threaded sleeve 1 can be removed from the outside of the screw body 2, and the screw body 2 can be replaced (the connection method between the screw body 2 and the external motor cannot be welding, and a detachable connection method in the prior art can be used for connection. The specific method is the prior art and is not limited here).
