Description

Technical Field

[0001] This utility model relates to the field of metering technology, specifically to a metering feeding device that can adapt to powders of different particle sizes. Background Technology

[0002] In plastic film production, metering feeding devices are typically used to precisely control the conveying amount and feeding speed of plastic powders of different particle sizes, so as to achieve continuity of the production process and consistency of product quality.

[0003] The feeding device of the metering machine usually uses a screw feeder to guide powder of different particle sizes into the metering machine. Because the gap between the screw blades and the outer shell of the screw feeder is usually small, coarse powder is easy to get stuck in the narrow channel or gap of the screw feeder during the screw conveying, which can easily lead to the risk of blockage.

[0004] Based on this, the present invention designs a metering feeder that can adapt to powders of different particle sizes to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a metering feeding device that can adapt to powders of different particle sizes.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A metering machine feeding device adaptable to powders of different particle sizes includes a feeding hopper and an anti-clogging mechanism. The anti-clogging mechanism includes a spiral feeding rod rotatably connected to the inner wall of the feeding hopper. A first motor is fixedly connected to the top end of the spiral feeding rod. A second motor is provided on one side of the feeding hopper. A cam rod is fixedly connected to the output shaft of the second motor. Several springs are fixedly connected to the end of the feeding hopper. A scraper is fixedly connected to the lower end of the surface of the spiral feeding rod. One side of the scraper contacts the lower end of the inner wall of the feeding hopper.

[0008] Furthermore, the surface of the spiral feed rod is fixedly connected with annularly distributed feeding blocks.

[0009] Furthermore, a guide rod is fixedly connected to the top of the spring, and the inner wall of the feed hopper is slidably connected to the surface of the guide rod.

[0010] Furthermore, a baffle plate, which is an iron component, is hinged to the upper surface of the feed hopper.

[0011] Furthermore, two magnets are embedded in the top of the feed hopper, and the top of the magnets is magnetically attached to the bottom of the cover plate.

[0012] Furthermore, a guide plate is fixedly connected to the upper end of the inner wall of the feed hopper, and the bottom of the guide plate forms an angle with the horizontal plane.

[0013] Furthermore, a corrugated sleeve is fixedly connected to the lower end of the surface of the feed hopper.

[0014] Furthermore, a limiting disc is fixedly connected to the surface of the guide rod, and the end of the feed hopper contacts the top of the limiting disc.

[0015] Furthermore, a fixed cylinder is fixedly connected to the top of the feed hopper, and the top of the first motor is fixedly connected to the inner top wall of the fixed cylinder.

[0016] Furthermore, a handle is fixedly connected to the top of the cover.

[0017] Beneficial effects

[0018] 1. The second motor, cam rod and spring work together to realize the reciprocating vibration of the feed hopper, thereby avoiding the risk of blockage inside the feed hopper and ensuring that powder of different particle sizes will not get stuck between the screw feed rod and the feed hopper. The scraper and screw feed rod scrape off the powder attached to the lower end of the inner wall of the feed hopper, ensuring smooth material discharge from the feed hopper.

[0019] 2. The material is dispersed by the material-dispersing block to reduce the clumping of the powder inside the hopper, thereby reducing the risk of blockage. The magnetic attraction and the baffle plate work together to seal the top of the hopper, preventing the powder from scattering out and reducing pollution to the working environment.

[0027] 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.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4 A metering feeder device adaptable to powders of different particle sizes includes a feed hopper 100 and an anti-blocking mechanism 200. The anti-blocking mechanism 200 includes a spiral feeding rod 203 rotatably connected to the inner wall of the feed hopper 100. A first motor 202 is fixedly connected to the top of the spiral feeding rod 203. A second motor 206 is provided on one side of the feed hopper 100. A cam rod 205 is fixedly connected to the output shaft of the second motor 206. Several springs 208 are fixedly connected to the end of the feed hopper 100. A scraper 204 is fixedly connected to the lower end of the surface of the spiral feeding rod 203. One side of the scraper 204 contacts the lower end of the inner wall of the feed hopper 100.

[0030] A metering machine is provided at the lower end of the surface of the feed hopper 100. The cam rod 205 includes a rotating rod and a cam. The surface of the rotating rod is rotatably connected to the upper end of the surface of the metering machine, and the surface of the rotating rod is fixedly connected to the inner wall of the cam. The surface of the second motor 206 is fixedly connected to the top of the metering machine.

[0031] It should be noted that the metering machine usually consists of a feed hopper 100, a metering device, a discharge pipe, a discharge valve, and a control device.

[0032] Measuring device: This is the core component of the measuring machine, containing various sensors such as load cells and volumetric measuring instruments. Load cells determine the quantity of materials by measuring their weight, while volumetric measuring instruments measure the volume occupied by the materials. These are common, well-known technologies in this field and are not particularly relevant to the technical issues addressed in this application; therefore, they are not described in detail.

[0033] When plastic powder needs to be metered, the plastic powder enters the metering machine through the feed hopper 100. The weight of the plastic powder is converted into an electrical signal by the weighing sensor. The control device processes and analyzes the electrical signal to obtain the weight of the raw material and can control the material discharge process according to the preset weight value.

[0034] In this embodiment of the invention, when plastic powder enters the feeding hopper 100 and needs to be guided to the metering machine, the first motor 202 and the second motor 206 are manually turned on. The output shaft of the first motor 202 rotates, driving the screw feeder 203 to rotate. The rotating screw feeder 203 guides the raw material in the feeding hopper 100 into the metering machine. The output shaft of the second motor 206 rotates, driving the cam rod 205 to rotate. The highest point of the cam rod 205 rotates and contacts the end of the feeding hopper 100, pushing the feeding hopper 100 upward and squeezing the spring 208. The highest point of the cam rod 205 moves away from the end of the feeding hopper 100. The elastic force of the spring 208 and the weight of the feeding hopper 100 itself cause the feeding hopper 100 to vibrate back and forth, thereby causing the powder in the feeding hopper 100 to fall into the metering machine in an orderly manner.

[0035] In this embodiment of the utility model, the second motor 206, the cam rod 205 and the spring 208 cooperate to realize the reciprocating vibration of the feed hopper 100, thereby avoiding the risk of blockage inside the feed hopper 100 and ensuring that powder of different particle sizes will not get stuck between the screw feed rod 203 and the feed hopper 100. The scraper 204 and the screw feed rod 203 scrape off the powder attached to the lower end of the inner wall of the feed hopper 100, ensuring smooth material discharge from the feed hopper 100.

[0036] In some embodiments, such as Figure 3-4As shown, in a preferred embodiment of this utility model, the surface of the spiral feeding rod 203 is fixedly connected with annularly distributed feeding blocks 209, the top end of the spring 208 is fixedly connected with a guide rod 207, the inner wall of the feeding hopper 100 is slidably connected to the surface of the guide rod 207, a cover plate 210 is hinged to the upper end of the surface of the feeding hopper 100, the cover plate 210 is an iron component, two magnets 212 are embedded in the top of the feeding hopper 100, the top of the magnets 212 are magnetically attracted to the bottom of the cover plate 210, a guide plate 213 is fixedly connected to the upper end of the inner wall of the feeding hopper 100, the bottom of the guide plate 213 forms an angle with the horizontal plane, a limiting plate 214 is fixedly connected to the surface of the guide rod 207, the end of the feeding hopper 100 contacts the top end of the limiting plate 214, and a handle 215 is fixedly connected to the top of the cover plate 210. The spiral feed rod 203, scraper 204, feed block 209 and guide plate 213 are all stainless steel components.

[0037] In this embodiment of the utility model, the material dispersing block 209 disperses the powder inside the feed hopper 100, reducing the occurrence of powder clumping and thus reducing blockage inside the feed hopper 100. The magnetic magnet 212 and the baffle plate 210 work together to seal the top of the feed hopper 100, thereby preventing the powder inside the feed hopper 100 from drifting out and reducing pollution to the working environment. The guide plate 213 guides the powder entering the feed hopper 100 to the center of the spiral feed rod 203, preventing the powder from accumulating on one side inside the feed hopper 100. The limiting plate 214 limits the downward movement height of the feed hopper 100.

[0038] In some embodiments, such as Figure 4 As shown, in a preferred embodiment of this utility model, a corrugated sleeve 201 is fixedly connected to the lower end of the surface of the feed hopper 100, and a fixed cylinder 211 is fixedly connected to the top of the feed hopper 100. The top end of the first motor 202 is fixedly connected to the inner top wall of the fixed cylinder 211. The corrugated sleeve 201 is a silicone component.

[0039] In this embodiment of the utility model, the corrugated sleeve 201 seals the space between the feed hopper 100 and the metering machine, preventing the powder from being dispersed into the air through the gap between the metering machine and the feed hopper 100. The fixed cylinder 211 protects the surface of the first motor 202, preventing the powder from adhering to the surface of the first motor 202.

[0040] It should be noted that the feeding hopper 100, the first motor 202, the screw feeder 203, the second motor 206, the baffle 210, the magnet 212, and the metering machine mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the first motor 202, the second motor 206, and the metering machine 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.

[0041] 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.
