Description

Technical Field

[0001] This utility model belongs to the field of abrasive grinding wheel technology, specifically relating to a resin abrasive storage vertical lifting quantitative feeding device. Background Technology

[0002] Grinding wheels are a type of abrasive. Their formation requires multiple processes. Currently, grinding wheel forming machines primarily use manual feeding. Patent CN106002667A describes a method using a vibratory lifting conveyor for feeding, but this method has the following drawbacks: 1. The vibratory feed trough directly feeds the forming machine, with the feeding amount determined solely by a material level detection switch. This results in inaccurate feeding and untimely feeding, as the trough is only replenished when the material level is insufficient, leading to excessively high replenishment levels and difficulty in timely replenishment. 2. The elevator feeds the vibratory conveyor trough by its own weight, causing splashing and dust generation. 3. The elevator is too large, making operation and maintenance inconvenient. Utility Model Content

[0003] This invention provides a resin abrasive storage vertical lifting quantitative feeding device to address the shortcomings of the prior art.

[0004] The technical solution adopted in this utility model is as follows: A resin abrasive storage vertical lifting quantitative feeding device includes a lifting conveying mechanism, a feeding conveying mechanism, and a controller. The feeding conveying mechanism is located at the discharge end of the lifting conveying mechanism, and a weighing feeding mechanism is located on the discharge side of the feeding conveying mechanism. The weighing feeding mechanism includes a feeding hopper, a weighing sensor, a feeding gate opening structure, and a feeding support. The feeding hopper is mounted on the feeding support via the weighing sensor, and the feeding hopper is equipped with a feeding gate. The feeding gate opening structure is connected to the feeding gate. The weighing sensor, the conveying motor of the lifting conveying mechanism, the power component of the feeding conveying mechanism, and the power component of the feeding gate opening structure are all electrically connected to the controller. The lifting conveyor transfers the lifted resin abrasive to the feeding conveyor, which then performs a secondary quantitative conveying before supplying it to the weighing and feeding mechanism. The weighing and feeding mechanism uses a weighing sensor to detect the weight of the resin abrasive to be fed, thus controlling the amount of resin abrasive in a dual manner to precisely control the amount of resin abrasive obtained in the next process. Furthermore, the feeding conveyor and weighing and feeding mechanisms serve as temporary storage devices for the two resin abrasives, enabling timely replenishment of the resin abrasive and preventing material shortages. The feeding hopper uses a gate-type discharge system, which is convenient for both discharging and cleaning.

[0005] In a preferred embodiment of this utility model, the feeding gate opening structure includes a gate opening cylinder. The piston rod of the gate opening cylinder is connected to the feeding gate and drives the feeding gate to rotate around the hinge. The extension and retraction of the gate opening cylinder can drive the opening and closing of the feeding gate, thereby realizing whether the resin abrasive is fed. The gate opening cylinder operates according to the controller's instructions. When the weight in the feeding hopper reaches the target, the gate opening gate opens for feeding. To ensure that the feeding gate opens and closes normally, it is preferable to set two gate opening cylinders to drive simultaneously.

[0006] As a preferred embodiment of this utility model, the inner wall of the feeding hopper is provided with an anti-stick coating to prevent the resin abrasive from sticking to the wall of the feeding hopper and being difficult to clean. In addition, the feeding part of the feeding hopper is generally triangular pyramidal in shape, which facilitates feeding.

[0007] In a preferred embodiment of this utility model, an opening barrier is provided on the outside of the feeding gate, and the opening barrier contacts the feeding gate. The ends of the opening connecting rods are respectively hinged to the piston rods of an opening cylinder. The upper part of the feeding gate is hinged to one side wall of the feeding hopper. Rotating the feeding gate outward away from the feeding hopper opens the feeding process, and rotating it closer to the feeding hopper closes the feeding process. The opening barrier is located on the side that blocks the opening and rotation of the feeding gate. Two opening cylinders pull the opening barrier simultaneously. In the initial state, the feeding gate is closed, and the opening barrier spans and presses against the feeding gate. When feeding is required, the piston rod of the opening cylinder extends, and the resin abrasive, under its own weight, squeezes the feeding gate to rotate outward and open it.

[0008] In a preferred embodiment of this utility model, the feeding and conveying mechanism includes a feeding bracket, a feeding belt conveyor, and a feeding conveying enclosure. The feeding belt conveyor is mounted on the feeding bracket, and the feeding conveying enclosure is connected to the frame of the feeding belt conveyor, forming a feeding and conveying cavity with the upper conveying surface of the feeding belt conveyor. A material level detector is installed inside the feeding and conveying cavity, and the material level detector is connected to a controller. The feeding conveying enclosure has a pre-reserved discharge port on the discharge side of the feeding and conveying cavity, and a discharge gate structure is provided at the discharge port. The feeding belt conveyor horizontally conveys the received resin abrasive, serving as an intermediate mechanism between the lifting and conveying mechanism and the weighing and feeding mechanism. It can act as a buffer area for the resin abrasive, avoiding untimely replenishment and reducing the number of replenishments, and also as a measure of the amount of resin abrasive supplied at one time. In conjunction with the weighing and feeding mechanism, it improves the accuracy of feeding to the next process.

[0009] In a preferred embodiment of this invention, a vibrating screen structure is provided on the feeding side of the feeding conveying chamber. The vibrating screen structure receives the discharge from the lifting conveying mechanism and feeds the material into the feeding conveying chamber. The vibrating screen structure shortens the vertical distance between the lifting conveying mechanism and the feeding conveying chamber, and disperses the resin abrasive to prevent clumping.

[0010] In a preferred embodiment of this utility model, the vibrating screen structure includes a vibrating screen support, a vibrating screen, a transfer feed hopper, a screening motor, a screening crank, and an eccentric block. The vibrating screen support is connected to the lifting frame of the lifting and conveying mechanism. The transfer feed hopper is mounted on the vibrating screen support, and the vibrating screen is positioned inside the transfer feed hopper and reciprocates relative to the transfer feed hopper. One end of the vibrating screen is hinged to the screening crank, and the other end of the screening crank is hinged to the eccentric block. The eccentric block is mounted on the output shaft of the screening motor, and the screening motor is fixed to the vibrating screen support. The rotation of the screening motor drives the eccentric block to rotate, and the screening crank rotates eccentrically accordingly, thereby driving the vibrating screen to reciprocate and keep the resin abrasive on the vibrating screen dispersed to prevent clumping. The outer wall of the vibrating screen is fitted with rollers, which reciprocate in cooperation with the roller grooves on the vibrating screen support. After passing through the vibrating screen, the resin abrasive falls from the transfer feed hopper into the feeding and conveying chamber, minimizing the time the resin abrasive is exposed.

[0011] In a preferred embodiment of this invention, a guide hopper is installed on the discharge side of the lifting and conveying mechanism, with the discharge port of the guide hopper corresponding to the feed port of the vibrating screen. The guide hopper prevents the resin abrasive from splashing and flying, ensuring that it falls accurately onto the vibrating screen.

[0012] In a preferred embodiment of this utility model, the lifting and conveying mechanism is a Z-type elevator, which has a bottom horizontal conveying section, a vertical conveying section, and a top horizontal conveying section; a storage hopper is provided above the bottom horizontal conveying section of the Z-type elevator. The Z-type elevator uses a belt conveyor, and the belt is equipped with inclined scrapers and side baffles. The vertical conveying section reduces the overall footprint.

[0013] As a preferred embodiment of this utility model, the storage hopper is provided with a discharge port located above the bottom horizontal conveying section. A stirring fork is installed inside the storage hopper, with one end of the stirring fork extending out of the storage hopper and connected to the output shaft of the stirring motor. The stirring motor includes a motor and a reducer, which provides rotational power to the stirring fork to stir the resin abrasive in the storage hopper and prevent the stored resin abrasive from clumping. The storage hopper is also equipped with a primary screen.

[0014] This invention prevents resin abrasive from clumping at the source by vibrating the conveying mechanism to keep it loose. The weighing and feeding mechanism is linked with the lifting and conveying mechanism and the feeding and conveying mechanism to ensure both weighing speed and feeding accuracy. In addition, both the feeding and conveying mechanism and the weighing and feeding mechanism have resin abrasive buffering function to improve the timeliness of replenishment.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: A resin abrasive storage and vertical lifting quantitative feeding device, such as Figure 1 As shown, it includes a lifting conveying mechanism 1, a feeding conveying mechanism 2 and a controller. The feeding conveying mechanism 2 is provided at the discharge end of the lifting conveying mechanism 1, and a weighing and feeding mechanism 3 is provided on the discharge side of the feeding conveying mechanism 2.

[0027] The lifting and conveying mechanism 1 used is a Z-type elevator and an elevator frame. The Z-type elevator is installed on the elevator frame and has a bottom horizontal conveying section, a vertical conveying section, and a top horizontal conveying section. A storage hopper 4 is provided above the bottom horizontal conveying section of the Z-type elevator. Figure 8 and 9 As shown, the storage hopper 4 is provided with a discharge port 41, which is located above the bottom horizontal conveying section. A stirring fork 44 is installed inside the storage hopper 4, and one end of the stirring fork 44 extends out of the storage hopper 4 and is connected to the output shaft of the stirring motor 43. The stirring motor includes a motor and a reducer, and is installed on one side of the bottom of the storage hopper to provide rotational power to the stirring fork to stir the resin abrasive in the storage hopper and prevent the stored resin abrasive from clumping. The storage hopper 4 is also equipped with a primary screen 42 to increase the capacity of the storage hopper.

[0028] The discharge port of hopper 4 corresponds to the bottom horizontal conveyor section. A gate is installed at the discharge port of hopper 4, and the gate is controlled by a telescopic cylinder to open and close the discharge port. The Z-type elevator uses a belt elevator, and the belt is equipped with inclined scrapers and side baffles. The vertical conveyor section reduces the overall footprint. The Z-type elevator vertically lifts the resin abrasive discharged from the hopper. The agitation discharge from the hopper disperses the resin abrasive and keeps it in a loose state. Vertical lifting reduces the space occupied by the Z-type elevator.

[0029] A guide hopper 11 is installed on the discharge side of the top horizontal conveyor section. The discharge port of the guide hopper 11 discharges the conveyed resin abrasive to the feeding conveyor mechanism 2.

[0030] The feeding and conveying mechanism 2 includes a feeding support 21, a feeding belt conveyor 22, and a feeding conveying enclosure 23. The feeding belt conveyor 22 is mounted on the feeding support 21, and the feeding conveying enclosure 23 is connected to the frame of the feeding belt conveyor 22, forming a feeding and conveying chamber with the upper conveying surface of the feeding belt conveyor 22. A material level detector is installed inside the feeding and conveying chamber, and the material level detector is connected to a controller. The feeding and conveying enclosure 23 has a pre-reserved discharge port on the discharge side of the feeding and conveying chamber, and a discharge gate structure is provided at the discharge port. The discharge gate structure adopts a discharge cylinder 231 and a discharge gate. The discharge cylinder is vertically arranged, and the piston rod of the discharge cylinder is connected to the discharge gate to drive the discharge gate to rise and fall.

[0031] A vibrating screen structure 24 is provided on the feeding side of the feeding and conveying chamber. The vibrating screen structure 24 includes a vibrating screen support 241, a vibrating screen 242, a transfer feeding hopper 243, a screening motor 244, a screening crank 245, and an eccentric block 246. The vibrating screen support 241 is horizontally installed on the lifting frame. The transfer feeding hopper 243 is installed at the installation port reserved on the vibrating screen support 241. Several rollers are installed on the outer wall of the screen body of the vibrating screen 242. Roller grooves are provided at the corresponding positions of the vibrating screen support. The rollers are located in the roller grooves, so that most of the vibrating screen is in the transfer feeding hopper. The upper end face of the vibrating screen corresponds to the discharge port of the guide hopper.

[0032] The side of the vibrating screen 242 is hinged to one end of the screening crank 245 via a pin. The other end of the screening crank 245 is hinged to an eccentric block 246, which is mounted on the output shaft of the screening motor 24. The screening motor 24 is fixed to the vibrating screen support 241. The rotation of the screening motor drives the eccentric block to rotate, causing the screening crank to rotate eccentrically, which in turn drives the vibrating screen to reciprocate, keeping the resin abrasive on the screen dispersed and preventing clumping. The outer wall of the vibrating screen is fitted with rollers, which reciprocate in conjunction with roller grooves on the vibrating screen support. After passing through the vibrating screen, the resin abrasive falls from the transfer feed hopper 243 onto the weighing and feeding mechanism 3, minimizing the time the resin abrasive is exposed. The vibrating screen structure shortens the vertical distance between the lifting and conveying mechanism and the weighing and feeding mechanism 3, and disperses the resin abrasive, preventing clumping.

[0033] The weighing and feeding mechanism 3 includes a feeding hopper 31, a weighing sensor 32, a feeding gate structure, and a feeding bracket 34. The feeding hopper 31 is installed on the feeding bracket 34 through the weighing sensor 32. The weighing sensor 32 serves as the main support for the feeding hopper. The feeding hopper is essentially suspended on the feeding bracket and only connected to the weighing sensor, which is fixed on the feeding bracket.

[0034] A feeding gate 311 is hinged to one side of the feeding hopper 31, and the feeding gate opening structure is connected to the feeding gate 311; thereby driving the feeding gate to open or close.

[0035] The feeding gate opening structure includes a gate opening cylinder 331. The piston rod of the gate opening cylinder 331 can be directly connected to the feeding gate 311, driving the feeding gate 311 to rotate around the hinge. The extension and retraction of the gate opening cylinder can drive the opening and closing of the feeding gate, thereby realizing whether the resin abrasive is fed. The gate opening cylinder operates according to the controller's instructions. When the weight in the feeding hopper reaches the target, the gate opening gate opens for feeding. To ensure normal opening and closing of the feeding gate, it is preferable to set two gate opening cylinders to drive simultaneously.

[0036] However, in order to control the feeding gate more easily, an opening barrier 332 is provided on the outside of the feeding gate 311. The opening barrier 332 contacts the feeding gate 311, and the end of the opening linkage 332 is hinged to the piston rod of an opening cylinder 331.

[0037] The upper part of the feeding gate is hinged to one side wall of the feeding hopper. Rotating the feeding gate outward away from the feeding hopper opens the feeding process, while rotating it closer to the feeding hopper closes the feeding process. The gate opening barrier is located on the side that prevents the feeding gate from opening and rotating. Two gate opening cylinders pull the gate opening barrier simultaneously. In the initial state, the feeding gate is closed, and the gate opening barrier spans and presses against the feeding gate. When feeding is required, the piston rod of the gate opening cylinder extends, and the resin abrasive, under its own weight, squeezes the feeding gate to rotate outward and open it.

[0038] To facilitate cleaning, the inner wall of the feeding hopper 31 is coated with an anti-stick coating to prevent the resin abrasive from sticking to the hopper wall. Furthermore, the feeding section of the hopper is shaped like a triangular pyramid for easy material discharge.

[0039] The weighing sensor 32 detects the weight of the resin abrasive in the feeding hopper and transmits it to the controller. The controller controls the gate opening cylinder 331, the screening motor 24, the feeding belt conveyor 22, and the conveying motor of the Z-type elevator to perform corresponding actions based on the detected weight information.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
