Description

Technical Field

[0001] The utility model relates to the technical field of vibration discs, in particular to a high-compatibility automatic feeding device. Background Art

[0002] The vibration plate is a device used for material transmission. The application range of the vibration plate is extremely wide. In the packaging equipment industry, the vibration plate needs to continue to separate and arrange the materials during the material sorting process to achieve effective feeding operations. At present, the vibration plates on the market have complex geometric shapes, thin sheets, and special-shaped parts that are difficult to feed, and are extremely prone to material jamming, stacking, and scratching, which increases the equipment failure rate and affects the production rate and qualified rate. Utility Model Content

[0003] The purpose of the utility model is to solve the problem in the prior art that the vibration disk is prone to material jamming, material stacking and material scratching, which leads to increased equipment failure rate and affects the production rate and qualified rate, and to propose a high-compatibility automatic feeding device.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a highly compatible automatic feeding device, comprising: a vibration plate and a feeding track spirally wound on the inner wall of the vibration plate, a primary screening section for screening irregularly stacked workpieces and pushing them back into the vibration plate along the conveying direction of the feeding track, a lateral screening section for pushing transversely flowing workpieces back into the vibration plate, a material acceleration section for increasing the conveying speed of the feeding track, a longitudinal screening section for pushing longitudinally flowing workpieces back into the vibration plate, and a sorting discharge section for counting the number and blowing the counted excess workpieces away from the discharge end one by one.

[0005] In the above-mentioned high-compatibility automatic feeding device, the primary screening part is provided with an adjusting baffle with one end extending through the wall of the vibration disk to the outside of the vibration disk, and the other end extending along the conveying direction of the feeding track and gradually reducing the feeding diameter of the feeding track to allow a single workpiece to pass through. The end of the adjusting baffle passing through the wall of the vibration disk is Z-shaped, and the Z-shaped part is fixed to the vibration disk by a locking member. The adjusting baffle away from the end of the Z-shaped part is provided with an adjusting push plate which can be adjustably installed on the outer wall of the vibration disk and one end passes through the wall to push the adjusting baffle. The adjusting baffle is pushed by adjusting the length of the adjusting push plate passing through the wall to adjust the feeding diameter of the feeding track.

[0006] In the above-mentioned high-compatibility automatic feeding device, the baffle is arc-shaped.

[0007] In the above-mentioned high-compatibility automatic feeding device, the horizontal screening part includes a first feed chute that avoids being recessed toward the outside of the vibration plate from the feeding track, and the bottom surface of the first feed chute is an inclined surface. The horizontal screening part also includes a first adjusting plate that can be adjustably installed on the outside of the vibration plate and one end of which is inserted from the outside of the vibration plate into the slot of the first feed chute, and a first arc-shaped scraper for scraping the stacked workpieces into the vibration plate. The length of the first adjusting plate extending to the slot is less than the diameter of the feeding track, and the upper surface of the first adjusting plate is flush with the surface of the feeding track. When the horizontal workpiece flows through the first adjustment plate, one end of the workpiece does not contact the first adjustment plate. Since one end of the workpiece is not supported by the first adjustment plate under the action of gravity, the workpiece falls from the first adjustment plate and flows back into the vibration plate from the first feed chute.

[0008] In the above-mentioned high-compatibility automatic feeding device, the material acceleration part is provided with an acceleration air outlet pipe whose air outlet end blows air in the feeding direction of the feeding track.

[0009] In the above-mentioned high-compatibility automatic feeding device, the longitudinal screening part includes a second feed chute that is prevented from being recessed toward the outside of the vibration plate from the feeding track, and the bottom surface of the second feed chute is an inclined surface. The longitudinal screening part also includes a second adjusting plate that can be adjustably installed on the outside of the vibration plate and one end of which is inserted from the outside of the vibration plate into the slot of the second feed chute, and a second arc scraper for scraping the stacked workpieces into the vibration plate. The length of the second adjusting plate extending to the slot is less than the diameter of the feeding track, and the upper surface of the second adjusting plate is flush with the surface of the feeding track. When the longitudinal workpiece flows through the second adjusting plate, one end of the workpiece does not contact the second adjusting plate. Since one end of the workpiece is not supported by the second adjusting plate under the action of gravity, the workpiece falls from the second adjustment plate and flows back into the vibration plate from the second feed chute.

[0010] In the above-mentioned high-compatibility automatic feeding device, the sorting and discharging part includes a photoelectric sensor for counting the number of workpieces flowing through and an air blow pipe for blowing away the incoming material from the rear when the front photoelectric sensor counts an appropriate number to ensure accurate counting. An adjustment strip groove is provided on the side wall of the vibration disk to enable the photoelectric sensor to move.

[0011] Compared with the existing technology, the utility model has the following advantages:

[0012] 1. The utility model can solve the problem of unsmooth conveying caused by material jamming and stacking by designing the primary screening part, the transverse screening part, the material acceleration part, the longitudinal screening part and the sorting and discharging part along the conveying direction of the feeding track. The material acceleration part can improve the transportation speed, meet the conveying needs of different materials, and has high compatibility.

[0013] 2. The stacked materials are screened for the first time by adjusting the baffle. The scraper and the adjusting plate can be used to scrape the horizontally and vertically stacked materials into the vibration plate and re-break them up, ensuring that only one material passes through the vibration plate in the horizontal and vertical directions. The air blowing port is accelerated to increase the transportation speed. When the discharge volume reaches the preset value, air is blown through the air blowing port to blow the excess materials back into the vibration plate.

[0014] 3. It can eliminate the phenomenon of material jamming and stacking.

[0015] 4. High discharging rate.

[0016] 5. The discharge quantity can be accurately controlled within the parameter range. BRIEF DESCRIPTION OF THE DRAWINGS

One end of the adjusting baffle plate 3 is in a Z shape, and the Z-shaped part passes through the vibration plate 1 to the outside and is fixed to the vibration plate 1 by a locking member. The adjusting baffle plate 3 away from one end of the Z-shaped part is abutted with an adjusting push plate 4, and one end of the adjusting push plate 4 movably passes through the vibration plate 1 to extend to the outside, and a fixing plate is provided on the vibration plate 1, and a strip groove is provided on the fixing plate. The plate 4 is fixed on the fixed plate by a locking piece, and the length of the adjusting push plate 4 inserted into the vibration disk 1 can be adjusted through the strip groove.

When the locking piece is loosened, the length of the first adjusting plate 6 inserted into the slot can be adjusted to meet the needs of conveying workpieces of different sizes. The length of the first adjusting plate 6 extending to the slot is less than the diameter of the feeding track 2, and the upper surface of the first adjusting plate 6 is flush with the surface of the feeding track 2. When the horizontal workpiece flows through the first adjusting plate 6, one end of the workpiece does not contact the first adjusting plate 6. Since one end of the workpiece is not supported by the first adjusting plate 6 under the action of gravity, the workpiece falls from the first adjusting plate 6 and flows back from the first unloading chute 5 to the vibration plate 1.

[0025] In order to prevent the stacked workpieces from flowing through the first adjusting plate 6, a first arc scraper 7 is provided on the wall of the vibration disk 1 on the side of the first adjusting plate 6. The first arc scraper 7 is L-shaped. The first arc scraper 7 has a first vertical plate and a first arc plate perpendicular to the first vertical plate. A strip groove is opened on the first vertical plate. The first vertical plate is fixed to the wall of the vibration disk 1 through the strip groove by a locking member. When the locking member is loosened, the height of the first arc plate can be adjusted to meet the transportation of products of different thicknesses. The stacked workpieces are scraped from the feeding track 2 to the vibration disk 1 through the first arc plate.

[0026] In order to speed up the conveying speed of the workpiece, a material acceleration part is set on the side of the horizontal screening part. The material acceleration part can increase the flow speed of the workpiece to improve efficiency. The material acceleration part is provided with an acceleration air outlet pipe 8 whose air outlet end blows air in the feeding direction of the feeding track 2.

A strip groove is provided on the second adjustment plate 10. The second adjustment plate 10 passes through the strip groove through a locking member to lock the second adjustment plate 10 on the second horizontal fixed plate. When the locking member is loosened, the length of the second adjustment plate 10 inserted into the slot can be adjusted to meet the needs of conveying workpieces of different sizes. When the longitudinal workpiece flows through the second adjustment plate 10, one end of the workpiece does not contact the second adjustment plate 10. Since one end of the workpiece is not supported by the second adjustment plate 10 under the action of gravity, the workpiece falls from the second adjustment plate 10 and flows back from the second unloading chute 9 to the vibration plate 1.

[0029] Specifically, in the present embodiment, the sorting and discharging section is mainly used to count the number and blow the counted excess workpieces away from the discharging end one by one. The sorting and discharging section includes a photoelectric sensor 12 for counting the number of workpieces flowing through and an air blowing pipe 13 for blowing away the incoming material from the rear to ensure accurate counting when the front end photoelectric sensor 12 counts an appropriate number of workpieces. An adjustment strip groove is provided on the side wall of the vibration disk 1 to enable the photoelectric sensor 12 to move. The air blowing pipe 13 is connected to an external air source through a hose. The photoelectric sensor 12 feeds back the sensed counting signal to the controller of the device. When the counted number is appropriate, the controller controls the air source to start, so that the air blowing pipe 13 is ventilated, and the workpieces flowing at the front end are blown away from the feeding track 2 and fall into the vibration disk 1 for re-transportation.
