Description

Technical Field

[0001] This utility model relates to a vacuum feeder, and more specifically to a scraper for a hopper, and to a vacuum feeder hopper with a vibrating scraper. Background Technology

[0002] A vacuum conveyor is a device that uses a vacuum pump to create a vacuum for conveying powder or granular materials; it is a type of pneumatic conveying.

[0003] A vacuum conveyor, also known as a vacuum feeder, is a dust-free, closed-loop pipeline conveying device that uses vacuum suction to transport granular and powdered materials. It utilizes the pressure difference between the vacuum and the ambient space to create gas flow within the pipeline, which in turn moves the powdered material, thus completing the conveying process. It is now widely used in various light and heavy industries, including chemical, pharmaceutical, food, metallurgy, building materials, and agricultural products.

[0004] Vacuum conveying is a closed-loop pipeline conveying method that eliminates dust pollution, improves the working environment, and reduces contamination of materials by the environment and personnel, thus increasing cleanliness. Because it's a pipeline system, it occupies little space, enabling the conveying of powders in confined spaces and creating a more aesthetically pleasing workspace. It is also not limited by distance. Furthermore, vacuum conveyors reduce manual labor intensity and increase work efficiency, making them the preferred method for conveying most powder materials.

[0005] When using existing vacuum feeders, the hopper is prone to blockage due to material contact with the inner wall, making it impossible to continuously convey materials under vacuum negative pressure. Vibrating scrapers are used to clean the material on the inner wall of the hopper. However, existing vibrating scrapers require a separate power unit to operate, resulting in an excessively large structure that occupies a large space in the hopper, reducing the material storage capacity or even preventing material storage, and easily causing material accumulation and blockage. Utility Model Content

[0006] One objective of this invention is to provide a new technical solution for a vacuum feeder hopper with a vibrating scraper.

[0007] According to a first aspect of the present invention, a vacuum feeder hopper with a vibrating scraper is provided, comprising a hopper shell, wherein a vibrating scraper mechanism is provided inside the hopper shell;

[0008] The vibrating scraper mechanism includes a linkage housing. A movable shaft is installed through the bottom of the linkage housing. An arc-shaped gear is fixedly installed on the movable shaft inside the linkage housing. Moving parts that are misaligned and meshed with the arc-shaped gear are movably installed on both sides of the linkage housing. A first crank rod is movably connected to the bottom of the moving parts on both sides. A scraper frame is movably connected to the other end of the first crank rod. A rubber plate is installed on the scraper frame on the side close to the hopper housing.

[0009] Rotary push rods are fixedly connected to both ends of the movable shaft, and a drive shaft is fixedly connected to the upper end of the linkage housing. A differential is meshed on the drive shaft, and three actuating levers are fixedly provided on the outside of the differential. The differential adjusts the rotation of the rotary push rods by means of the three actuating levers.

[0010] Furthermore, a fixed bracket is welded to the upper end of the hopper shell, and the drive shaft passes through the fixed bracket.

[0011] Furthermore, a servo motor is fixedly mounted on the upper part of the fixed bracket, and the upper end of the transmission shaft is bonded to the output end of the servo motor.

[0012] Furthermore, the vibrating scraper mechanism is rotatably located at the bottom of the fixed bracket, and the linkage housing is located on the center line of the hopper housing, with the rubber plate attached to the inner wall of the hopper housing.

[0013] Furthermore, the moving part includes a rack portion and a connecting portion, the rack portion being movably located inside the linkage housing, and the rack portion being meshed with the arc-shaped gear.

[0014] Furthermore, sliding grooves are provided on both sides of the connecting part, and limiting rods are fixedly provided on both sides of the interior of the linkage housing, with the limiting rods movably positioned inside the sliding grooves.

[0015] Furthermore, one end of the first crank rod is movably connected to one end of the connecting part via a connecting pin, and the other end of the first crank rod is movably connected to the upper part of the scraper frame via a connecting pin.

[0016] Furthermore, the middle part of the first crank rod is movably connected to the second crank rod via a connecting pin, and the other end of the second crank rod is movably connected to the lower part of the scraper frame via a connecting pin.

[0017] Furthermore, the two first crank rods are movably connected to a third crank rod on one side near the connecting part by a connecting pin, and the other ends of the two third crank rods are movably connected to each other by a connecting pin.

[0018] Furthermore, the rotating push rods on both sides are at an angle of 45° to 90°, and both rotating push rods on both sides are set upwards.

[0019] According to one embodiment of this disclosure, the vibrating scraper is driven by a servo motor. When the servo motor outputs power, it can drive the scraper frame and the rubber plate to rotate inside the hopper shell, so that the scraper frame and the rubber plate can clean the residual and sticky materials inside the hopper shell, preventing the hopper shell from becoming blocked and causing the materials to be unable to be conveyed.

[0020] The scraper frame and rubber plate are connected by a linkage housing. Inside the linkage housing, the moving parts on both sides are connected by an arc gear. The arc gear is connected and rotated by a movable shaft. A rotating push rod is provided on the movable shaft. A servo motor drives the differential to rotate. A toggle rod is provided on the differential. The toggle rod moves the rotating push rod, which drives the movable shaft and the arc gear to rotate. This allows the moving parts to control the scraper frame and rubber plate to vibrate back and forth, thus cleaning the material in the hopper housing. Upward rotating push rods are provided on both sides, which allow the toggle rod to move the rotating push rod back and forth. That is, the toggle rod on one side moves the rotating push rod down, and the toggle rod on the other side moves the rotating rod back, thus achieving reciprocating movement.

[0021] Furthermore, the moving part is connected to the scraper frame via the first crank rod, and the first crank rod is connected to the lower part of the scraper frame via the second crank rod. This maintains the stability of the scraper frame and facilitates contact between the scraper frame and the rubber plate and the inner wall of the hopper shell. In order to maintain the stability of the scraper frames and rubber plates on both sides, the first crank rods on both sides are connected to each other via the third crank rod, which supports and bends the scraper frames and rubber plates on both sides, improving the stability of the contact between the scraper frame and the rubber plate and the inner wall of the hopper shell.

[0036] In this embodiment, preferably, a fixed bracket 2 is welded to the upper end of the hopper shell 1, and the drive shaft 5 passes through the fixed bracket 2.

[0037] It should be noted that the fixed bracket 2 welded to the upper part of the hopper shell 1 is used to install and connect the vibrating scraper mechanism 4, maintain the stability of the vibrating scraper mechanism 4, and also maintain the rotation of the vibrating scraper mechanism 4.

[0051] It should be noted that a third crank rod 413 is provided on both sides of the first crank rod 409 on both sides, and the third crank rods 413 on both sides are movably connected by a connecting pin 414, which facilitates the support and folding of the scraper frame 410 and rubber plate 411 on both sides, and keeps the scraper frame 410 and rubber plate 411 in contact with the inner wall of the hopper shell 1.

[0052] In this embodiment, preferably, the two rotating push rods 405 are at an angle of 45° to 90°, and both rotating push rods 405 are upward;

[0053] It should be noted that the included angle between the rotating push rods 405 on both sides is 45° to 90° and both are set upwards, so that the actuating rod 403 can move the rotating push rods 405 on both sides, which facilitates reciprocating operation and realizes the vibration adjustment of the scraper frame 410 and the rubber plate 411. The vibration can knock the hopper shell 1 to clean the material.

[0054] The specific operational procedures for this application are as follows:

[0055] When in use, the material is put into the hopper shell 1, and then the servo motor 3 is started. The servo motor 3 can drive the vibrating scraper mechanism 4 at the bottom of the fixed bracket 2 through the transmission shaft 5. In turn, the transmission shaft 5 can drive the vibrating scraper mechanism 4 at the bottom to rotate, so that the scraper frame 410 and the rubber plate 411 can rotate inside the hopper shell 1. The scraper frame 410 and the rubber plate 411 rotate the material inside the hopper shell 1, which is convenient for cleaning the residual and blocked material on the hopper shell 1.

[0056] A differential 402 is provided on the drive shaft 5. The differential 402 drives the actuating lever 403 to rotate. The differential 402 is designed so that the rotational speed of the actuating lever 403 is different from that of the drive shaft 5, which facilitates continuous vibration of the scraper frame 410 and the rubber plate 411. That is, the differential 402 drives the actuating lever 403 to rotate, so that the actuating lever 403 can actuate the rotating push rod 405. When the rotating push rod 405 is actuated, the movable shaft 404 can drive the arc gear 406 to rotate. When the arc gear 406 rotates, it can drive the moving parts 407 on both sides to move and adjust, so that the moving parts 407 can move and adjust through the first The crank rod 409, the second crank rod 412, and the third crank rod 413 adjust the left and right vibration of the scraper frame 410 and the rubber plate 411. The setting of the first crank rod 409 and the second crank rod 412 can maintain the balance and stability of the scraper frame 410 and the rubber plate 411, preventing the scraper frame 410 and the rubber plate 411 from tilting and failing to adhere to the inner wall of the hopper housing 1. The setting of the third crank rod 413 is used to support the scraper frame 410 and the rubber plate 411 on both sides to maintain stability. This allows the scraper frame 410 and the rubber plate 411 to continuously and repeatedly vibrate the inner wall of the hopper housing 1 when cleaning the material in the hopper housing 1, effectively preventing material residue and blockage.

[0057] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
