Description

Technical Field

[0001] This invention relates to the field of concrete production equipment technology. More specifically, this invention relates to an automatic feeding device and its method of use. Background Technology

[0002] Ultra-high performance concrete (UHPC), as a new material, possesses excellent mechanical properties and durability, making it popular among engineers and leading to its increasingly widespread engineering applications. However, its high cost and immature design specifications mean that it is currently mostly used in critical and special structural parts of engineering projects. This results in a very small usage volume compared to ordinary concrete, making the construction of fully automated UHPC production lines too costly and reducing the profit margins of enterprises. Therefore, the current method of supplying UHPC for on-site casting involves setting up a mixer and raw material storage area on-site, serving as a simple mixing plant. To improve supply efficiency, raw materials are mixed according to the mix proportions at the factory, packaged in ton bags, and transported to the site. When producing UHPC finished products, the mixed raw materials from the ton bags are directly added to the feed inlet of the mixer, along with water, and then mixed.

[0003] However, the current method of feeding ton bags requires additional manual labor to cut open the ton bags, which not only increases the labor cost of production, but also poses a safety hazard because the operators work on the narrow operating platform at the top of the mixer feed. Furthermore, the dust raised during the falling of powdery goods pollutes the construction environment and also poses a health hazard to the workers.

[0004] Currently, there is no optimization for the manual cutting of ton bags for feeding, in order to reduce production costs, improve construction safety, and reduce dust pollution and health hazards to workers. Summary of the Invention

[0005] One object of the present invention is to solve at least the above-mentioned problems and to provide at least the advantages that will be described later.

[0006] Another objective of this invention is to provide an automatic feeding device and its usage method to solve the technical problems of high difficulty and low efficiency in handling broken ton bags in the prior art.

[0007] To achieve these objectives and other advantages according to the present invention, in one aspect, the present invention provides an automatic feeding device, comprising:

[0008] The feeding chamber has an upper feeding inlet at the top and a lower feeding inlet at the bottom. A limiting groove is symmetrically connected vertically on the inner wall of the feeding chamber. The upper end of the limiting groove and the side facing the center of the feeding chamber are open. A support member is connected to the upper end of the lower feeding inlet of the feeding chamber.

[0009] The bag-cutting mechanism includes a column connected to a support member along the middle of the feeding chamber. A piercing blade is provided on the top of the column. A transverse cutting assembly is provided on the side of the column and between each side of the limiting groove. The transverse cutting assembly includes a horizontally arranged slide rail. One end of the slide rail is located in the limiting groove on the corresponding side and is slidably connected to the limiting groove vertically. The other end is slidably connected to the column vertically. A sliding blade is slidably connected on the slide rail. A return spring is connected between the end of the sliding blade near the limiting groove and the end of the slide rail. A cable is connected to the end of the sliding blade facing away from the limiting groove. A pulley is provided on the column corresponding to each cable. The cable extends upward after passing over the pulley and is fixedly connected to the upper end of the column.

[0010] Preferably, the top of the feeding chamber is provided with a dustproof assembly, which includes multiple dustproof plates arranged symmetrically. Each dustproof plate is hinged to the top side of the feeding chamber. There is a gap between adjacent dustproof plates and a traction spring is connected thereto. A flexible material plate is covered above each gap and is fixed to one of the dustproof plates. The inner sides of the multiple dustproof plates form a feeding port, and the size of the feeding port is smaller than the cross-sectional size of the ton bag.

[0011] Preferably, the dustproof plate has a trapezoidal plate structure.

[0012] Preferably, a sleeve is slidably connected to the column, and one end of each slide rail facing the column is fixedly connected to the top of the sleeve.

[0013] Preferably, the outer side wall of the column is provided with a locking hole along the vertical direction, and the inner side of the sleeve is provided with a protruding strip corresponding to the locking hole, the protruding strip sliding vertically along the locking hole.

[0014] Preferably, a diagonal brace is connected between the lower outer end of the sleeve and the bottom of the slide rail.

[0015] Preferably, the piercing blade includes four symmetrically arranged triangular pieces, each of which is fixed to the top of the column, and adjacent triangular pieces are fixedly connected to form a cutting edge. The slide rail and the limiting groove are symmetrically arranged in four places and are located in the same vertical plane as the cutting edge.

[0016] Preferably, a rotating ring is fitted at the upper end of the column below the piercing blade. The rotating ring is located above the fixed end of the cable. The rotating ring is connected to the column through a bearing. The outer diameter of the rotating ring is not less than the outer diameter of the lower end of the piercing blade. A cutting edge is provided on the outer side of the rotating ring along the spiral direction.

[0017] On the other hand, the present invention also provides a method of using an automatic feeding device, comprising the following steps:

[0018] S1. Hoist the ton bag to the top of the feed inlet;

[0019] S2. Lower the ton bag until the bottom of the ton bag contacts the dustproof plate. Press the dustproof plate downwards and rotate it until the bottom of the ton bag falls to the piercing blade and is pierced.

[0020] S3. The ton bag continues to slide down, and the puncture area increases until the bottom of the ton bag contacts the sliding blade. Under the weight of the ton bag, the slide rail slides down along the column, and the sliding blade slides along the slide rail toward the column. During the sliding process, the sliding blade cuts the bottom of the ton bag, and the goods inside the ton bag fall from the cut. The dustproof plate contacts the side of the ton bag and squeezes the goods inside the ton bag, accelerating the falling of the goods.

[0021] S4. After the goods stop falling, lift the ton bag. The dustproof plate scrapes the side of the ton bag, and the remaining goods are disturbed and continue to fall. During the lifting process of the ton bag, the sliding blade and the slide rail gradually return to their original positions under the pull of the return spring.

[0022] S5. After all the goods in the ton bag have fallen out, remove the ton bag and proceed with the next feeding.

[0023] The present invention has at least the following beneficial effects: The automatic feeding device and its method of use of the present invention utilize the weight of the ton bag to allow the ton bag to be cut open by the piercing blade and the sliding blade, and the goods inside the ton bag fall out. The dustproof plate promotes the falling of the remaining goods and prevents dust from drifting out. Afterwards, the slide rail and the sliding blade return to their original positions by the action of the spring. Repeated operation realizes automatic cutting and feeding of the ton bag, reducing the labor cost and production safety hazards in concrete production, and reducing dust pollution to the environment.

[0024] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0032] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0033] It should be noted that, unless otherwise specified, the experimental methods described in the following embodiments are all conventional methods, and the reagents and materials described are all commercially available unless otherwise specified. In the description of this invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0034] like Figure 1-4 As shown, the present invention provides an automatic feeding device, comprising:

[0035] The feeding chamber has an upper feeding port 1 at its upper end and a lower feeding port 2 at its lower end. A limiting groove 3 is symmetrically connected vertically on the inner wall of the feeding chamber. The upper end of the limiting groove 3 and the side facing the center of the feeding chamber are open. A support member 4 is connected to the upper end of the lower feeding port 2 of the feeding chamber.

[0036] The bag-cutting mechanism includes a column 5 connected to a support member 4 along the middle of the feeding chamber. A piercing blade 6 is provided on the top of the column 5. A transverse cutting assembly is provided between the side of the column 5 and the limiting groove 3 on each side. The transverse cutting assembly includes a horizontally arranged slide rail 7. One end of the slide rail 7 is located in the limiting groove 3 on the corresponding side and is slidably connected to the limiting groove 3 vertically. The other end is slidably connected to the column 5 vertically. A sliding blade 8 is slidably connected on the slide rail 7. A return spring 9 is connected between the end of the sliding blade 8 near the limiting groove 3 and the end of the slide rail 7. A pull cable 10 is connected to the end of the sliding blade 8 facing away from the limiting groove 3. A pulley 11 is provided on the column 5 corresponding to each pull cable 10. The pull cable 10 extends upward after passing over the pulley 11 and is fixedly connected to the upper end of the column 5.

[0037] One end of the slide rail 7 of the bag cutting mechanism is installed in the limiting groove 3, and the other end slides relative to the column 5 to limit the slide rail 7 during vertical sliding. The ton bag first contacts the piercing blade 6 and is pierced. Then, during the downward movement, it contacts the sliding blade 8 on the side. Under the action of gravity, it presses down on the slide rail 7. The pull cable 10 is turned by the pulley 11. Since the length of the pull cable 10 is constant, it pulls the sliding blade 8 to move horizontally. The return spring 9 extends. As the sliding blade 8 moves towards the column 5, it cuts and breaks the ton bag that is pressed down from above. When the amount of material falling out of the ton bag is reduced to the basic completion, under the action of the return spring 9, the pull cable 10 is pulled to drive the sliding blade 8 back to its original position and away from the column 5, so as to achieve the effect of reverse cutting and disturbing the remaining material in the ton bag.

[0038] The automatic feeding device of the present invention utilizes the weight of the ton bag containing the goods to make the ton bag cut itself on the piercing blade 6 and the sliding blade 8, so that the goods inside the ton bag fall into the feeding port 2, solving the problem of traditional manual repeated cutting and realizing automated bag breaking and feeding.

[0039] In another technical solution, such as Figure 1-2 As shown, a dustproof assembly is provided on the top of the feeding chamber. The dustproof assembly includes multiple dustproof plates 12 arranged symmetrically. Each dustproof plate 12 is hinged to the top side of the feeding chamber. A gap is left between adjacent dustproof plates 12 and a traction spring 13 is connected thereto. A flexible material plate 14 is provided above each gap. The flexible material plate 14 is fixed to one of the dustproof plates 12. The inner sides of the multiple dustproof plates 12 form a feeding port 15. The size of the feeding port 15 is smaller than the cross-sectional size of the ton bag.

[0040] Dustproof components are installed to prevent dust during the cutting and unloading of ton bags. The inlet 15 in the middle of the dustproof plate 12 is smaller than the cross-sectional size of the ton bag containing the goods. It connects with the ton bag to prevent the ton bag from falling too quickly. When the dustproof plate 12 flips down around the hinge, it contacts and scrapes the outside of the ton bag to prevent dust from drifting out. At the same time, it disturbs the goods inside the ton bag to help it fall. The goods inside the ton bag continue to fall, and the ton bag moves down until all the goods inside the ton bag have fallen. The ton bag is then lifted, and the dustproof plate 12 returns to its initial position under the action of the traction spring 13, waiting for the next ton bag to fall. The flexible material plate 14 itself has a certain ability to stretch and deform, and is relatively soft. It can follow the movement of the dustproof plate 12 to cover the gaps and prevent dust from overflowing.

[0041] In another technical solution, such as Figure 2 As shown, the dustproof plate 12 has a trapezoidal structure. The long side of the trapezoidal plate is hinged to the top of the feeding chamber, and the short side is used to contact the ton bag, forming a gap between adjacent inclined sides.

[0042] In another technical solution, such as Figure 1 , 6 As shown, a sleeve 17 is slidably connected to the column 5, and one end of each slide rail 7 facing the column 5 is fixedly connected to the top of the sleeve 17.

[0043] The sleeve 17 is slidably sleeved and limited on the column 5. The sleeve 17 is fixedly connected to the slide rail 7 and supports the slide rail 7. The upper end of the cable 10 is fixedly connected to the column 5 and is set as the fixed end. The fixed end is located below the piercing blade 6 and above the sleeve 17.

[0044] In another technical solution, such as Figure 1 , 6 As shown, a locking hole 18 is vertically formed on the outer side wall of the column 5, and a protruding strip 19 is provided on the inner side of the sleeve 17 corresponding to the locking hole 18. The protruding strip 19 slides vertically within the locking hole 18. By setting the locking hole 18 and the protruding strip 19, the horizontal stability of the automatic cross-cutting component is ensured.

[0045] In another technical solution, such as Figure 1 , 6 As shown, a diagonal brace 20 is connected between the lower outer end of the sleeve 17 and the bottom of the slide rail 7 to improve the stability of the structural connection between the slide rail 7 and the sleeve 17 and ensure the cutting quality.

[0046] In another technical solution, such as Figure 1-2As shown in Figure 6, the piercing blade 6 includes four symmetrically arranged triangular pieces, each of which is fixed to the top of the column 5, and adjacent triangular pieces are fixedly connected to form a blade 21. The slide rail 7 and the limiting groove 3 are symmetrically arranged in four places and are located in the same vertical plane as the blade 21.

[0047] By designing the structure of the piercing blade 6, the top of the piercing blade 6 first pierces the center of the bottom of the ton bag. When the ton bag falls under the action of gravity, the inclined blades 21 on all four sides continue to cut outward from the already pierced center at the bottom of the ton bag. The blades 21, the slide rail 7, and the sliding blade 8 are located on the same vertical plane. The cutting of the bottom of the ton bag by the sliding blade 8 is basically on the same vertical plane as the cutting direction of the blade 21, which reduces the cutting path and cutting difficulty of the sliding blade 8 and increases the cutting range of the ton bag.

[0048] In another technical solution, such as Figure 6 As shown, a rotating ring 22 is fitted on the upper end of the column 5 below the piercing blade 6. The rotating ring 22 is located above the fixed end of the cable 10. The rotating ring 22 is connected to the column 5 through a bearing. The outer diameter of the rotating ring 22 is not less than the outer diameter of the lower end of the piercing blade 6. A cutting blade 23 is provided on the outer side of the rotating ring 22 along the spiral direction.

[0049] A rotating ring 22 is mounted on the column 5 via bearings. The rotating ring 22 is equipped with a cutting blade 23. When the ton bag falls due to gravity and is pierced at the bottom center by the piercing blade 6, it continues to move downwards and contacts the cutting blade 23 on the rotating ring 22. Simultaneously, the rotating ring 22 rotates due to its spiral configuration, cutting the bottom area of ​​the ton bag that may not have been cut between the sliding blade 8 and the piercing blade 6. At the same time, when the ton bag is pulled up to release the goods, the cutting blade 23 on the rotating ring 22 cuts the ton bag in the opposite direction or slightly hooks onto the ton bag to form an inclined surface and continues cutting, causing any remaining goods on the inner surface near the center of the ton bag's bottom to slide off and fall off. Furthermore, the width and thickness of the cutting blade 23 can be gradually increased in the downward spiral direction to match the change in the cutting surface as the ton bag moves vertically.

[0050] The present invention also provides a method of using an automatic feeding device, combined with Figure 1-6 As shown, it includes the following steps:

[0051] S1. Hoist the ton bag to the top of the feed inlet 1 and use lifting equipment to lift the ton bag.

[0052] S2. Lower the ton bag until the bottom of the ton bag contacts the dustproof plate 12. Press the dustproof plate 12 to rotate downwards until the bottom of the ton bag falls to the piercing blade 6 and is pierced. The ton bag continues to slide down, and the piercing area becomes larger.

[0053] S3. The ton bag continues to slide down, and the puncture area increases until the bottom of the ton bag contacts the sliding blade 8. Under the weight of the ton bag, the slide rail 7 slides down along the column, and the sliding blade 8 slides along the slide rail 7 toward the column. During the sliding process, the sliding blade 8 cuts the bottom of the ton bag, and the goods inside the ton bag fall from the cut. The dustproof plate 12 contacts the side of the ton bag, squeezing the goods inside the ton bag, disturbing the internal agglomeration of the goods, and accelerating the falling of the goods.

[0054] S4. After the goods stop falling, lift the ton bag. The dustproof plate 12 scrapes the side of the ton bag, and the remaining goods are disturbed and continue to fall. During the lifting process of the ton bag, the sliding blade 8 and the slide rail 7 gradually return to their original positions under the pull of the return spring 9.

[0055] S5. Repeat operation S4 until all the goods in the ton bag have fallen out, then remove the ton bag and proceed with the next feeding.

[0056] This invention utilizes the weight of the ton bag to allow it to be cut open sequentially by the piercing blade 6 and the sliding blade 8, allowing the contents of the ton bag to fall into the feed inlet. The dustproof plate 12 helps any remaining contents fall off and prevents dust from escaping. Furthermore, the device automatically returns to its original position under the action of the return spring 9, reducing labor costs and safety hazards in concrete production and minimizing dust pollution to the environment.

[0057] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
