Description

Technical Field

[0001] This utility model relates to the technical field of feeding mechanism for button attaching machines, specifically a feeding mechanism for button attaching machines with a dust cover. Background Technology

[0002] A button attaching machine is a specialized automatic sewing machine primarily used for attaching buttons of regular shapes and for sewing processes involving "nailing" and "drip" stitching, such as attaching labels, tags, and caps. Button attaching machines offer superior performance and can quickly adapt to various sewing requirements. Through simple operation, the button attachment method can be changed, such as from 4 holes to 2 holes, or the shape of "=" and "X" can be easily switched using a lever. In addition, button attaching machines are characterized by easy operation, energy saving, high efficiency, low noise, and long service life.

[0003] The button-attaching machine uses a vibratory feeder for feeding. A vibratory feeder is a widely used automated device in industrial production, mainly used to realize the automatic sorting, orientation and feeding of materials. The working principle of the vibratory feeder is that the pulse electromagnet set under the hopper makes the hopper vibrate up and down, and with the cooperation of the inclined spring, the hopper makes the hopper torsion vibration around the vertical axis. This vibration mode enables materials (such as screws, rivets, buttons, etc.) to be neatly arranged and transported along a specific track, realizing automated feeding.

[0004] However, the feeding mechanism of the button-attaching machine is exposed to the air, and dust in the air will accumulate in the feeding mechanism and contaminate the material in the feeding mechanism; therefore, it does not meet the existing requirements. In response, we propose a feeding mechanism for the button-attaching machine with a dust cover. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding mechanism for a button-attaching machine with a dust cover, so as to solve the problems mentioned in the background art, such as the button-attaching machine feeding mechanism being exposed to the air, where dust in the air will accumulate in the feeding mechanism and contaminate the material in the feeding mechanism.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for a button-making machine with a dust cover, comprising a vibrating feeding disc, a feeding guide rail on the outer surface of the vibrating feeding disc, a dust cover plate detachably installed above the vibrating feeding disc, a through circular hole in the middle of the dust cover plate, twelve rubber dustproof sheets arranged in a circular array inside the circular hole, the sides of two adjacent rubber dustproof sheets fitting together, the arc-shaped edges of the rubber dustproof sheets being fixed to the dust cover plate, a feeding guide tube fixed on the upper surface of the dust cover plate, the axis of the feeding guide tube coinciding with the axis of the circular hole and having the same inner diameter, and a shielding cover plate detachably installed above the rubber dustproof sheets.

[0007] Preferably, the side of the shielding cover is in sliding contact with the inner wall of the feed conduit, the bottom surface of the shielding cover is provided with an annular groove, and a column is fixed at the center of the upper surface of the vibrating feeder.

[0008] Preferably, a positioning strip is fixed on the upper surface of the rubber dustproof sheet, and the positioning strip is arc-shaped with its center aligned with the center of the rubber dustproof sheet.

[0009] Preferably, the positioning strip is snapped into the inner side of the annular groove on the bottom surface of the cover plate, and both the inner and outer surfaces of the positioning strip are provided with snapping strips. The inner side of the annular groove is provided with two sealing grooves, and the snapping strip is snapped into the sealing grooves.

[0010] Preferably, a sealing ring is snapped onto the bottom surface of the dust cover, and the inner and outer edges of the sealing ring are both bent downwards at a 90-degree angle. An annular positioning plate is also fixed to the bottom surface of the dust cover.

[0011] Preferably, the bottom end of the annular positioning plate is bent outward at a 90-degree angle, and the outer diameter of the bottom end of the annular positioning plate is consistent with the inner diameter of the vibrating feeding plate.

[0012] Preferably, a compression-inflatable airbag is provided between the inner edge of the annular positioning plate and the sealing ring, and the compression-inflatable airbag is bonded and fixed to the annular positioning plate by adhesive.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model covers the top of the vibrating feeder with a dustproof cover plate, adds twelve rubber dustproof sheets with their sides fitting together in the middle round hole of the dustproof cover plate, and adds a shielding cover plate above the rubber dustproof sheets to block dust in the air and prevent dust from entering the vibrating feeder and contaminating the materials.

[0015] 2. This utility model removes the cover plate and then adds material into the feed pipe. The weight of the material squeezes the rubber dustproof sheets that are attached to each other on the sides and passes through the gaps between the adjacent rubber dustproof sheets. This ensures that the material is added smoothly into the vibrating feeder without opening the dustproof cover plate, while preventing dust from entering the vibrating feeder.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figures 1 to 3 As shown, a feeding mechanism for a button-making machine with a dust cover includes a vibrating feeding plate 1, a feeding guide rail 2 on the outer surface of the vibrating feeding plate 1, a dust cover 3 detachably installed on the top of the vibrating feeding plate 1, a sealing ring 7 snapped into the bottom surface of the dust cover 3, the inner and outer edges of the sealing ring 7 being bent downwards at a 90-degree angle, and an annular positioning plate 8 fixed to the bottom surface of the dust cover 3.

[0023] The bottom end of the annular positioning plate 8 is bent outward at a 90-degree angle, and the outer diameter of the bottom end of the annular positioning plate 8 is consistent with the inner diameter of the vibrating feed plate 1. An extrusion airbag 9 is provided between the inner edge of the annular positioning plate 8 and the sealing ring 7. The extrusion airbag 9 and the annular positioning plate 8 are bonded and fixed with adhesive. After the feeding guide rail 2 and the vibrating feed plate 1 are assembled, the gap between the feeding guide rail 2 and the vibrating feed plate 1 is filled by the sealing ring 7, and gas is filled into the extrusion airbag 9, so that the extrusion airbag 9 expands and presses the inner edge of the sealing ring 7 against the inner wall of the feeding guide rail 2, so that the inner edge of the sealing ring 7 is completely attached to the inner wall of the vibrating feed plate 1, thereby ensuring the overall sealing performance of the dust cover 3 and the vibrating feed plate 1 after assembly.

[0024] like Figure 2 and Figure 4 As shown, a through circular hole is provided in the middle of the dust cover plate 3. Twelve rubber dustproof sheets 6 are arranged in a circular array inside the circular hole. The sides of two adjacent rubber dustproof sheets 6 are attached to each other. The arc-shaped edge of the rubber dustproof sheet 6 is fixed to the dust cover plate 3. A feed guide 4 is fixed on the upper surface of the dust cover plate 3. The axis of the feed guide 4 coincides with the axis of the circular hole and the inner diameter is the same. A shielding cover plate 5 is detachably installed above the rubber dustproof sheets 6. The dust cover plate 3 covers the vibrating feeder plate 1, and the rubber dustproof sheets 6 and the shielding cover plate 5 shield the central circular hole of the dust cover plate 3 to prevent dust from entering the vibrating feeder plate 1 and contaminating the material.

[0025] The side of the shielding cover 5 slides in contact with the inner wall of the feed conduit 4. The bottom surface of the shielding cover 5 is provided with an annular groove. A column is fixed at the center of the upper surface of the vibrating feeder 1. The column grips the shielding cover 5, making it easy to remove the shielding cover 5 from the inside of the feed conduit 4. The shielding cover 5 also shields the rubber dustproof sheet 6, preventing dust from adhering to the surface of the rubber dustproof sheet 6. This prevents dust from being present on the surface of the rubber dustproof sheet 6 during feeding and from entering the vibrating feeder 1 with the material.

[0026] A positioning strip 10 is fixed on the upper surface of the rubber dustproof sheet 6. The positioning strip 10 is arc-shaped and its center is consistent with the center of the rubber dustproof sheet 6. The positioning strip 10 is snapped into the inner side of the annular groove on the bottom surface of the cover plate 5. Both the inner and outer surfaces of the positioning strip 10 are provided with snap-fit ​​strips 11. The inner side of the annular groove is provided with two sealing grooves. The snap-fit ​​strips 11 are snapped into the sealing grooves. The positioning strip 10 and the snap-fit ​​strips 11 seal the connection gap between the cover plate 5 and the rubber dustproof sheet 6. The positioning strip 10 and the snap-fit ​​strips 11 increase the connection strength between the cover plate 5 and the rubber dustproof sheet 6, ensuring that the cover plate 5 will not slide up and down inside the feed guide 4 due to the vibration of the vibrating feed tray 1 during operation.

[0027] Working principle: First, the dust cover 3 is placed on top of the vibrating feeder 1. At this time, the outer surface of the bottom end of the annular positioning plate 8 is attached to the inner wall of the vibrating feeder 1, and the inner wall of the bottom end of the dust cover 3 is attached to the outer surface of the vibrating feeder 1. The sealing ring 7 is located between the feeding guide rail 2 and the vibrating feeder 1. Gas is injected into the compression inflation bladder 9, causing the compression inflation bladder 9 to expand and compress the inner edge of the sealing ring 7, so that the inner edge of the sealing ring 7 is completely attached to the inner wall of the vibrating feeder 1, thereby ensuring that the sealing ring 7 connects the vibrating feeder 1 and the dust cover 3. After the joint is completely sealed, the shielding cover 5 is placed inside the feed conduit 4 and pushed downward until the bottom surface of the shielding cover 5 is in contact with the rubber dustproof sheet 6. At this time, the positioning strip 10 on the upper surface of the rubber dustproof sheet 6 enters the inner side of the annular groove at the bottom of the shielding cover 5, and the snap strips 11 on the inner and outer surfaces of the positioning strip 10 snap into the sealing groove of the annular groove. The shielding cover 5, the rubber dustproof sheet 6 and the dustproof cover 3 cover the vibrating feeder 1 from above, preventing dust in the air from entering the vibrating feeder 1 and contaminating the material inside the vibrating feeder 1.

[0028] When material needs to be added to the vibrating feeder 1, simply pull up the cover plate 5 to separate the cover plate 5 from the positioning strip 10 on the upper surface of the rubber dustproof sheet 6. Then pour the material into the feed guide 4. The material falls under the action of gravity and squeezes the rubber dustproof sheet 6, causing the rubber dustproof sheets 6, which are stuck together on the sides, to separate. The material falls through the gap between the rubber dustproof sheets 6 after they are separated. After the material is added, the rubber dustproof sheet 6 returns to its original shape and seals the central hole of the dustproof cover plate 3. The normal addition of material is not affected without opening the dustproof cover plate 3.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
