[0002] Paste food is a type of food with unique texture and characteristics. Paste food usually has high viscosity and certain fluidity, presenting a thick paste-like form. Common paste foods include jam, peanut butter, honey, bean paste filling, condensed milk, etc. These foods are often made from a variety of raw materials through fine processing and are rich in nutrients. Paste food has a rich and delicate taste, which can bring a unique taste experience. In the food processing industry, the filling of paste food is an important link. Due to its special physical properties, paste food faces some unique challenges during the filling process. The viscosity of paste food is relatively high and its fluidity is relatively poor. The filling equipment needs to have sufficient pressure to ensure that the food can flow out of the filling head smoothly and be accurately injected into the packaging container.

[0003] With the continuous improvement of consumers' requirements for food quality and packaging, the filling accuracy and packaging effect of paste food have received increasing attention. When the blanking head stops discharging, due to the residual pressure inside it and the characteristics of the food itself, it is easy to form a filamentous connection at the discharge port. The wire-drawing problem will not only affect the appearance quality of the product, but may also lead to inaccurate filling volume. Content of the Utility Model

The inner wall of the lower cavity of the filling head body is rotatably connected with a baffle plate. A wire-drawing prevention mechanism is arranged in the mounting block, which drives the linkage tooth plate to slide through the rotation of the transmission gear, thereby driving the positioning column, the limiting column and the piston head to slide, and driving the suction air bag to contract.

[0006] Preferably, the mounting block is designed to be strip-shaped, and an opening is provided between the mounting block and the filling head body.

[0007] With the above technical solution, due to the strip-shaped design of the mounting block, it is convenient to install components, and the opening between the mounting block and the filling head body facilitates material suction.

One end of the connecting rod penetrates the surface of the filling head body, and one end of the connecting rod is fixedly connected to the rotating shaft of the baffle plate.

[0011] With the above technical solution, since a transmission chain is provided between the first sprocket and the second sprocket, the first sprocket drives the second sprocket to rotate.

[0020] 2. A transmission gear and a linkage tooth plate are provided. When the device is working, the first sprocket rotates to drive the transmission gear to mesh with the two linkage tooth plates, so that the linkage tooth plate drives the positioning column to move, which is convenient for the positioning column to drive the limit column and perform subsequent material suction operations, thereby improving the efficiency of material suction. The stability of material suction is improved through two-way material suction. During filling, the suction airbag expands and resets to push the sucked product to be re-fed, thereby improving practicality;

[0021] 3. A connecting rod and a material baffle plate are provided, so that when the device is working, the first sprocket is driven to rotate by the driving motor, so that the first sprocket drives the second sprocket to rotate through the transmission chain, and then the second sprocket drives the material baffle plate to rotate through the connecting rod, so that after the device absorbs the material, the material baffle plate is rotated and closed, thereby further preventing the product from flowing out and improving the anti-wire drawing effect.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-6 , the present invention provides a technical solution: a wire-drawing prevention blanking head for paste food filling, including a filling head body 1, a mounting block 2, a driving motor 3, a first sprocket 4, a second sprocket 5, a transmission chain 6, a connecting rod 7, a material blocking plate 8, a transmission gear 9, a linkage tooth plate 10, a positioning column 11, a limiting column 12, a piston head 13 and a suction airbag 14. The lower outer surface of the filling head body 1 is fixedly connected with a mounting block 2. The mounting block 2 is designed in a long strip shape, and there is an opening between the mounting block 2 and the filling head body 1. The output end of the driving motor 3 penetrates the surface of the support plate of the mounting block 2, and the output end of the driving motor 3 is fixedly connected with the rotating shaft of the first sprocket 4. When using this device, first, the material is fed through the filling head body 1. After the material feeding is completed, the driving motor 3 drives the first sprocket 4 to rotate, so that the rotating shaft of the first sprocket 4 drives the transmission gear 9 to rotate, and the transmission gear 9 drives the two linkage tooth plates 10 to slide and unfold.

[0031] A support plate is arranged on the upper rear surface of the mounting block 2, and a driving motor 3 is fixedly connected to the support surface of the mounting block 2. The inner support surface of the mounting block 2 is rotatably connected with a first sprocket 4. A transmission chain 6 is arranged between the outer surfaces of the first sprocket 4 and the second sprocket 5. One end of the connecting rod 7 penetrates the surface of the filling head body 1, and one end of the connecting rod 7 is fixedly connected with the rotating shaft of the material blocking plate 8. After the linkage tooth plate 10 slides, the linkage tooth plate 10 drives the limiting column 12 to move through the positioning column 11 at one end, so that the piston head 13 at one end of the limiting column 12 extracts the air in the suction airbag 14, causing the suction airbag 14 to deform and contract.

[0032] A second sprocket 5 is arranged below the first sprocket 4. A connecting rod 7 is arranged between the second sprocket 5 and the lower end of the filling head body 1. The anti-drawing mechanism includes a transmission gear 9 which is rotatably connected to the rear surface of the mounting block 2. A groove is arranged on the rear surface of the mounting block 2, and two positioning columns 11 are slidably connected to the inner wall of the groove of the mounting block 2. One end of the positioning column 11 is fixedly connected with a linkage tooth plate 10. A limiting column 12 is fixed on the side surface of one end of the positioning column 11, and a piston head 13 is fixed at one end of the limiting column 12. Two suction air bags 14 are fixedly connected between the filling head body 1 and the inner wall of the opening of the mounting block 2. After the suction air bags 14 contract, a negative pressure is formed between the suction air bags and the paste product, so that the two suction air bags 14 suck the residual paste product to prevent the product from dripping and drawing, ensuring the appearance quality of the product.

[0033] A baffle 8 is rotatably connected to the inner wall of the lower cavity of the filling head body 1. An anti-drawing mechanism is arranged in the mounting block 2. The rotation of the transmission gear 9 drives the sliding of the linkage tooth plate 10, thereby driving the sliding of the positioning column 11, the limiting column 12 and the piston head 13 to drive the contraction of the suction air bag 14. The rotating shaft of the transmission gear 9 is fixedly connected to the rotating shaft of the first sprocket 4. Tooth blocks are arranged on the surface of the linkage tooth plate 10 facing the transmission gear 9, and the linkage tooth plate 10 is meshed with the transmission gear 9 through the tooth blocks. A spring is connected between the positioning column 11 and the mounting block 2. The piston head 13 penetrates through the side opening of the suction air bag 14. When sucking the product, the first sprocket 4 drives the second sprocket 5 to rotate through the transmission chain 6, so that the second sprocket 5 drives the baffle 8 to rotate through the connecting rod 7, so that the baffle 8 seals the filling head body 1, further improving the blocking effect on the product and preventing the product from falling and drawing.

[0034] Working principle: When using the anti-drawing blanking head for filling paste food, first, the driving motor 3 drives the first sprocket 4 and the transmission gear 9 to rotate, so that the transmission gear 9 drives the two linkage tooth plates 10 to move, so that the linkage tooth plates 10 drive the positioning columns 11 and the limiting columns 12 to slide, and the suction air bag 14 is pumped air through the piston head 13, so that the suction air bag 14 deforms to suck the material to prevent dripping and drawing. At the same time, the first sprocket 4 drives the second sprocket 5 to rotate through the transmission chain 6, so that the second sprocket 5 drives the baffle 8 to rotate through the connecting rod 7 to seal the filling head body 1 to further prevent the product from flowing out, increasing the overall practicability.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
