Description

Technical Field

[0001] This utility model relates to the field of chemical production technology, and in particular to a device for improving the packaging efficiency of food-grade phosphate products. Background Technology

[0002] In the food additive production field, sodium tripolyphosphate, sodium hexametaphosphate, and sodium pyrophosphate must all be packaged in clean areas. Taking sodium tripolyphosphate as an example, based on actual production conditions, the packaging material silos are strictly separated into automated line packaging silos and manual silos. Most customers use automated line packaging, but some special customers prefer manual packaging. Due to the on-site equipment layout, automated and manual packaging cannot be substituted. During the production process, according to customer needs, qualified products from the previous process are transported to either the automated line packaging silo or the manual silo, where packaging personnel complete the packaging operation.

[0003] However, when the automated line malfunctions, products stored in the automated packaging hopper cannot be packaged in a timely manner, and excessive material accumulation can cause a "hopper overflow" and spillage, resulting in product defects. Furthermore, when a laboratory technician finds a product to be defective and unsuitable for packaging at the packaging port, the products in the automated packaging line cannot be transferred to the manual hopper in a timely manner, where waste bags are disposed of.

[0004] This will affect packaging speed and output, and if too much material accumulates in the automatic packaging chamber, the machine will need to be stopped for cleaning, causing production stoppages and impacting the company's profits. Summary of the Invention

[0005] The technical problem to be solved by this utility model is that when the automatic packaging line malfunctions, the automatic packaging hopper is prone to bursting.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a device for improving the packaging efficiency of food-grade phosphate products, including a guide pipe connected to the bottom of an automatic packaging hopper, a screw conveyor connected to the output end of the guide pipe, and a scraper conveyor connected to the output end of the screw conveyor. The output end of the scraper conveyor is connected to the inner top of the manual packaging hopper, and a switch structure is provided on the guide pipe.

[0007] Preferably, the switch structure includes an electric push rod fixedly connected to the movable end of the guide tube, and the output end of the electric push rod is fixedly connected to a piston structure slidably arranged inside the fixed end of the guide tube.

[0008] Preferably, the piston structure includes a sealing ball slidably connected within the fixed end of the feed tube, the outer wall of the sealing ball being in contact with the inner wall of the feed tube.

[0009] Preferably, the top of the outer wall of the sealing ball is provided with a receiving groove for accommodating materials, and when the materials flow through the gap between the sealing ball and the guide pipe, the materials come into contact with the materials in the receiving groove.

[0010] Preferably, a guide sleeve is fixedly connected to the inner top of the guide tube, and an extension rod is slidably connected inside the guide sleeve, with the extension rod arranged parallel to the guide tube.

[0011] Preferably, a limiting seat is fixedly installed at the bottom of the feed tube, and a stop plate is fixedly connected to the bottom of the extension rod. The outer circumferential surface of the stop plate is in contact with the inner sidewall of the feed tube, and when the stop plate contacts the limiting seat, the piston structure blocks the feed tube, and the stop plate is always located below the output end of the feed tube.

[0012] Preferably, the electric push rod is connected to a control module, which is used to control the timed extension and retraction of the electric push rod. The control module includes a time relay and a relay module.

[0013] This invention provides a device for improving the packaging efficiency of food-grade phosphate products, which has the following beneficial effects.

[0014] 1. When the automatic packaging line malfunctions, the time relay and relay module in the control module control the electric push rod to extend and retract at regular intervals, driving the piston structure to open the feed pipe. Material in the automatic packaging hopper can then be quickly conveyed to the manual packaging hopper via the feed pipe, screw conveyor, and scraper conveyor. This design prevents the automatic packaging hopper from overflowing due to excessive material accumulation, thus preventing product defects. It eliminates the need to stop production for material cleaning, significantly reducing downtime and effectively ensuring the continuity of food additive production and packaging.

[0015] 2. The outer wall of the sealing ball in the piston structure is in contact with the inner wall of the feed tube, and a receiving groove is provided at the top. When the material flows through the gap between the sealing ball and the feed tube, the friction between the material and the material in the receiving groove is used to reduce the wear of the sealing ball caused by the material flow and ensure the sealing between the sealing ball and the feed tube.

[0018] Figure 2 This is a schematic diagram of the internal structure of the feed tube in an embodiment of this utility model.

[0020] like Figure 1 and Figure 2 As shown, this utility model provides a device for improving the packaging efficiency of food-grade phosphate products, including a guide pipe 3 connected to the bottom of the automatic packaging hopper 1, a screw conveyor 6 connected to the output end of the guide pipe 3, and a scraper conveyor 8 connected to the output end of the screw conveyor 6. The output end of the scraper conveyor 8 is connected to the inner top of the manual packaging hopper 2, and a switch structure is provided on the guide pipe 3.

[0021] When the automatic packaging production line malfunctions, the discharge valve at the bottom of the automatic packaging hopper 1 is closed, and the switch structure on the guide pipe 3 is opened. The material enters the screw conveyor 6 through the guide pipe 3, and the screw conveyor 6 transports the material to the scraper conveyor 8. The scraper conveyor 8 then lifts the material to the manual packaging hopper 2, which maintains the storage and output of the material. At this time, the number of workers on the manual packaging line is increased to cope with the downtime of the automatic packaging production line.

[0022] The screw conveyor 6 is driven by the drive motor 7 to rotate the internal auger for feeding. When there is too much material in the automatic packaging hopper 1, the material is transported to the screw conveyor 6 through the guide pipe 3. If the material pressure inside the screw conveyor 6 is too high, it can easily cause damage to the screw conveyor 6. Therefore, by adding a switch structure to control the opening and closing of the guide pipe 3, a stable working environment for the screw conveyor 6 is maintained.

[0023] like Figure 1 and Figure 2 As shown. The switching structure includes an electric push rod 4 fixedly connected to the movable end of the guide tube 3. The output end of the electric push rod 4 is fixedly connected to a piston structure slidably arranged inside the fixed end of the guide tube 3. By extending the output end of the electric push rod 4, the electric push rod 4 pushes the piston structure out from the fixed end of the guide tube 3, and the piston structure enters the automatic packaging hopper 1. The guide tube 3 is then opened, and materials can enter the guide tube 3 for transfer.

[0024] like Figure 2As shown. The piston structure includes a sealing ball 10 slidably connected within the fixed end of the feed tube 3, with the outer wall of the sealing ball 10 fitting against the inner wall of the feed tube 3. The sealing ball 10 is used to seal the feed tube 3. While achieving a sealed state, the end of the sealing ball 10 away from the electric push rod 4 is sharp, allowing the electric push rod 4 to easily push the sealing ball 10 into the automatic packaging hopper 1.

[0025] As a preferred embodiment of this utility model, the top of the outer wall of the sealing ball 10 is provided with a receiving groove for accommodating materials. When the material flows through the gap between the sealing ball 10 and the guide pipe 3, the material comes into contact with the material in the receiving groove. After the sealing ball 10 is pushed out of the guide pipe 3, the material enters the receiving groove of the sealing ball 10. When the material in the automatic packaging hopper 1 enters the guide pipe 3, the material passes through the gap between the sealing ball 10 and the guide pipe 3. At this time, the flowing material rubs against the material inside the receiving groove, thereby avoiding wear on the sealing ball 10 and ensuring the sealing between the sealing ball 10 and the guide pipe 3.

[0026] like Figure 2 As shown. A guide sleeve 11 is fixedly connected to the inner top of the feed tube 3, and an extension rod 9 is slidably connected inside the guide sleeve 11. The extension rod 9 is arranged parallel to the feed tube 3. The guide sleeve 11 ensures the stability of the movement of the extension rod 9, and the electric push rod 4 is connected to the piston structure through the extension rod 9.

[0027] like Figure 2 As shown. A limiting seat 12 is fixedly installed at the bottom of the feed tube 3. A stop plate 13 is fixedly connected to the bottom of the extension rod 9. The outer circumferential surface of the stop plate 13 is in contact with the inner wall of the feed tube 3. When the stop plate 13 contacts the limiting seat 12, the piston structure seals the feed tube 3. The stop plate 13 is always located below the output end of the feed tube 3. When the feed tube 3 is not in use, the sealing ball 10 is located inside the feed tube 3. The limiting seat 12 supports the stop plate 13, and the stop plate 13 supports the extension rod 9. The extension rod 9 provides stable support for the sealing ball 10, thereby ensuring the sealing of the feed tube 3.

[0028] As a preferred embodiment of this utility model, the electric push rod 7 is connected to a control module. The control module is used to control the timed extension and retraction of the electric push rod 7. The control module includes a time relay and a relay module. The guide tube 3 adopts a timed extension and retraction method to alleviate the equipment pressure during material transfer. An electronic time relay is selected, and a timed period of 30 seconds is set. After 30 seconds, an electrical signal is output to the relay module. After receiving the electrical signal, the relay module controls the on / off state of the electric push rod motor to realize the timed opening and closing of the guide tube 3.
