Description

Technical Field

[0001] This utility model relates to the field of additive filling technology, specifically to a food additive production and filling equipment. Background Technology

[0002] Food additives are chemical or natural substances added to improve food quality, extend shelf life, or enhance sensory characteristics. Common types include preservatives, colorings, flavorings, and antioxidants. Filling is a crucial process for ensuring the stability and safety of additives. It involves sealing the food to prevent oxygen, moisture, and microbial contamination, thus preventing degradation or inactivation. Food additive production and filling equipment is required for filling food additives.

[0003] According to the Chinese patent "A filling device for feed additive production" authorized announcement number "CN221341324U", this utility model can make it easy to restrict the position of the limiting plate by contacting the outer wall of the positioning rod with the outer wall of the connecting plate. This makes it convenient for the opening of the outer packaging bag to be placed on the top of the slide rail. Through the reaction force of the tension spring, the moving plate can slide inside the connecting plate, so that multiple connecting plates move away from the outer wall of the connecting cylinder. In this way, the limiting plate drives the limiting groove to squeeze and restrict the opening of the packaging bag to the outer wall of the slide rail, thereby restricting and supporting the position of the opening of the packaging bag, which is convenient for the field of feeding additive filling technology.

[0004] While the aforementioned application addresses the issue of workers needing to constantly hold the bag opening during filling by using a spring-driven limiting plate to fix the bag opening onto the slide rail when packaging additives in packaging bags, it still requires workers to repeatedly open the bag opening because brand-new packaging bags are often used for filling additives. This not only increases the workload of workers but also affects filling efficiency because the opening of brand-new packaging bags is usually difficult to open.

[0005] Based on this, the present invention designs a food additive production and filling equipment to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a food additive production and filling equipment.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A food additive production and filling device includes a machine body, and a feeding hopper is fixedly connected inside the machine body.

[0009] Furthermore, the clamping mechanism includes two opposing clamping blocks disposed below the hopper. An air pump is fixedly connected inside the machine body, and the interiors of both clamping blocks are connected to the air pump. A drive assembly is disposed between the clamping blocks and the machine body.

[0010] Furthermore, the machine body is equipped with a worktable inside, and a conveyor belt is provided on the surface of the worktable, with the conveyor belt located below the hopper.

[0011] Furthermore, the drive assembly includes a slide rail disposed inside the body, the clamping block being slidably connected to the slide rail, one end of the slide rail extending through the back of the body and the other end being slidably connected to the support columns on both sides of the body.

[0012] Furthermore, a protective shell is fixedly connected to the back of the machine body, one end of the slide rail extends through the machine body and is slidably connected to the inner wall of the protective shell, and a servo motor is fixedly connected to the top of the protective shell.

[0013] Furthermore, the drive end of the servo motor penetrates into the protective shell and is fixedly connected to a reciprocating screw. The bottom end of the reciprocating screw is rotatably connected to the inner bottom wall of the protective shell, and one end of the slide rail that penetrates out of the machine body is set on the surface of the reciprocating screw.

[0014] Furthermore, two electric push rods are fixedly connected to the lower part of the slide rail, and the two electric push rods are arranged opposite each other. Near both ends of the slide rail, the driving end of the slide rail is fixedly connected to the back of the clamping block.

[0015] Furthermore, a sealing strip, made of rubber, is fixedly connected to the surface of the opening end of the clamping block. Beneficial effects

[0016] 1. By setting up two clamping blocks driven by electric push rods in conjunction with an air pump to replace mechanical clamping, when the additive is filled into a brand new packaging bag, the clamping blocks hold the packaging bag and the negative pressure of the clamping blocks will adsorb the packaging bag onto the two clamping blocks. Then, the movement of the clamping blocks will open the bag, eliminating the step of workers opening the bag opening, reducing the workload of workers and effectively improving work efficiency.

[0017] 2. By installing a conveyor belt below the two clamping blocks, the staff can directly add the packaging bag between the two conveyor belts during filling. This can effectively reduce the probability of the packaging bag tilting and tipping over due to the staff's mistake when placing the packaging bag between the two clamping blocks. At the same time, the conveyor belt can also transport the filled packaging bag backward, reducing the workload of the staff. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4A food additive production and filling device includes a body 100, a feeding hopper 200 fixedly connected inside the body 100, and a clamping mechanism 300. The clamping mechanism 300 includes two opposing clamping blocks 310 disposed below the feeding hopper 200. An air pump 330 is fixedly connected inside the body 100, and the interiors of the two clamping blocks 310 are connected to the air pump 330. A drive assembly 350 is disposed between the clamping blocks 310 and the body 100.

[0028] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, in a preferred embodiment of this utility model, a workbench 110 is provided inside the machine body 100, and a conveyor belt 340 is provided on the surface of the workbench 110. The conveyor belt 340 is located below the hopper 200. The drive assembly 350 includes a slide rail 352 disposed inside the machine body 100. The clamping block 310 is slidably connected to the slide rail 352. One end of the slide rail 352 extends through the back of the machine body 100, and the other end is slidably connected to the support columns on both sides of the machine body 100. A protective shell 351 is fixedly connected to the back of the machine body 100. The end of the slide rail 352 extending through the machine body 100 is slidably connected to the support columns on both sides of the machine body 100. The inner wall of the protective shell 351 is fixedly connected to the top of the protective shell 351. The drive end of the servo motor 354 passes through the protective shell 351 and is fixedly connected to the reciprocating screw 353. The bottom end of the reciprocating screw 353 is rotatably connected to the inner bottom wall of the protective shell 351. One end of the slide rail 352 that passes through the machine body 100 is set on the surface of the reciprocating screw 353. Two electric push rods 320 are fixedly connected to the bottom of the slide rail 352. The two electric push rods 320 are arranged opposite to each other. Near both ends of the slide rail 352, the drive end of the slide rail 352 is fixedly connected to the back of the clamping block 310.

[0029] In this embodiment, the hopper 200 is a relatively mature existing technology. Its main structure adopts a conical design, with internal distributing blades and a stirring shaft, connected to the transmission system via a sprocket. The stirring component is driven by a motor to rotate the distributing blades, convectively mixing the materials and improving their flowability. The transmission mechanism transmits power through a rack, sprocket, or worm gear, adjusting the stirring speed and discharging rhythm to adapt to different material characteristics. The discharge control uses a solenoid valve linked to a weight sensor to achieve quantitative discharging. The weight sensor is installed on the conveyor belt, and when the packaging bag reaches the qualified weight, it will fall onto the conveyor belt. On conveyor belt 340, a weight sensor detects changes in the weight of the conveyor belt and controls the solenoid valve to close via an electrical signal. This device requires the addition of a sensor on conveyor belt 340 and a control panel on the machine body 100. Conveyor belt 340, servo motor 354, and air pump 330 are electrically connected to the control panel. When the packaging bag moves directly below the hopper 200, conveyor belt 340 stops moving. At the same time, servo motor 354 and electric push rod 320 drive clamping block 310 to clamp the packaging bag. After the packaging bag falls onto conveyor belt 340, it resumes operation under the action of the weight sensor.

[0030] The clamping mechanism 300 of this device is located below the feeding hopper 200, and the movement of the slide rail 352 is limited by the thread of the reciprocating screw 353, so its range of motion is always between the conveyor belt 340 and the feeding hopper 200. Furthermore, the components of the clamping mechanism 300 are all connected to the frame of the machine body 100, so they will not affect the feeding, stirring, feeding or other normal operation of the feeding hopper 200. At the same time, most food additives are in the form of powder or granules, so the physical state of the additives will not affect this device.

[0031] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, a sealing strip 311 is fixedly connected to the surface of the opening end of the clamping block 310. The sealing strip 311 is made of rubber. The two clamping blocks 310 are respectively arranged on the longitudinal sides of the hopper 200, and the conveyor belt 340 is arranged laterally below the slide rail 352.

[0032] In this embodiment, the conveyor belt 340 is driven by a motor located inside the machine body 100. The side and top surfaces of the conveyor belt 340 are provided with belt bodies. The side surfaces are complete belt bodies, and the top surfaces are narrower belt bodies, so that after the packaging bag falls onto the top surface, it can move backward under the conveying of the top surface belt body, and the two conveyor belts 340 rotate in opposite directions.

[0033] In use, the food additives are fully mixed in the hopper 200 and then fed through the discharge port.

[0034] During the unloading process, the worker adds the packaging bag between two conveyor belts 340. The packaging bag is transported forward by the friction of the two conveyor belts 340. When the packaging bag moves directly below the unloading port, the reciprocating screw 353 drives the slide rail 352 to move to a position flush with the opening of the packaging bag. Then, two electric push rods 320 push two clamping blocks 310 to fit against the two sides of the packaging bag. At the same time, the air pump 330 extracts the air from the clamping blocks 310, creating a negative pressure inside the two clamping blocks 310. At this time, the reciprocating screw 353 continues to rotate, and the slide rail 352 will... The upward movement causes the two clamping blocks 310 and the packaging bag to move upward as well. At the same time, the two electric push rods 320 cause the two clamping blocks 310 to retract, opening the bag opening. Then, the food additive is filled into the packaging bag through the discharge port of the hopper 200. When the weight inside the packaging bag reaches the qualified weight, under the action of gravity, the downward gravity is greater than the adsorption of the packaging bag by the two clamping blocks 310, and the packaging bag falls onto the surface of the conveyor belt 340. It is then transported backward by the conveyor belt 340, and then the next packaging bag is filled. The above steps are repeated.

[0035] Note: The reciprocating screw 353 is characterized by two threaded grooves with the same pitch but opposite directions, connected at both ends by a transition curve. The rotation of the reciprocating screw 353 causes the side of the helical groove to push the slider placed in the helical groove to perform axial reciprocating motion.

[0036] It should be noted that the reciprocating lead screw 353, air pump 330, electric actuator 320 and servo motor 354 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the air pump 330, electric actuator 320 and servo motor 354 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
