Description

Technical Field

[0001] This invention relates to the field of material sorting technology, and in particular to a feeding device for lightweight and easily clogged materials. Background Technology

[0002] In the field of material sorting, to prevent material from accumulating too quickly on the vibrating feed pan and overflowing from the feed pan, a transition feed hopper is usually installed to receive the material falling from the collection hopper and decelerate it before it falls into the vibrating feed pan. However, the feeding, conveying, and sorting of thin, lightweight materials is often very difficult. First, their mass and density are generally low, and their operating state is easily altered by the combined effects of conveyor resistance and material-to-material resistance. Second, such materials are prone to blockage during conveying, especially in the vibrating feeding stage. When material falls from the collection hopper to the vibrating feed pan, it is very easy for it to get stuck in the transition feed hopper, preventing the material from effectively falling into the vibrating feed pan and causing feeding failure.

[0003] The common methods to solve the problem of material blockage during the feeding process of thin, lightweight materials are to reduce the feeding speed and slow down the feeding slope. However, this often sacrifices production efficiency, which is undesirable for users.

[0004] The purpose of this invention is to solve the problem of easy clogging of thin, lightweight materials during vibration feeding in the prior art, and to provide a feeding device for lightweight, easily clogged materials. Summary of the Invention

[0005] To address the technical problems mentioned in the background section, the present invention provides a feeding device for lightweight and easily clogged materials.

[0006] The present invention is achieved by the following technical solution: a feeding device for lightweight and easily clogged materials, including a base, a vibrator assembly elastically supported on the top of the base, a vibrating plate connected to a material slide on the vibrating end of the top of the vibrator assembly, a feeding hopper assembly for conveying materials is suspended above the vibrating plate, a vibrating component extending into the output end of the feeding hopper assembly is provided on the top of the vibrating plate, the vibrating component can keep the vibration synchronized with the vibrating plate to agitate the material accumulated after entering the feeding hopper assembly from the collection hopper, so that the material passively overcomes the resistance between materials and falls into the vibrating plate at an accelerated speed.

[0007] As a further improvement to the above solution, four rubber pads are arranged in a rectangular shape on the top of the base, and four rubber pads are adapted to be provided on the bottom of the vibrator housing of the vibrator assembly, with vibration isolation springs provided between the two corresponding rubber pads.

[0008] As a further improvement to the above solution, the vibrator assembly includes a vibrator housing, a U-shaped plate, a gasket, a spring, a cover plate, and an internal coil core assembly. The vibrator housing and the U-shaped plate are connected as one unit by the spring. The top of the U-shaped plate is fixedly connected to the bottom of the vibrating material tray. The internal coil core assembly is enclosed and installed in the vibrator housing by the cover plate.

[0009] As a further improvement to the above solution, the vibrator assembly also includes a gasket, and the vibrator housing and U-shaped plate are connected as a whole by the gasket, spring and screw.

[0010] As a further improvement to the above solution, a fixed pressure plate is provided on the vibrator housing, a pressure plate is provided on the top of the base, an adjusting screw is inserted into the fixed pressure plate, the bottom of the adjusting screw is threaded through the pressure plate, and a nut that cooperates with the bottom of the adjusting screw is provided at the bottom of the pressure plate.

[0011] As a further improvement to the above solution, the vibrating component is an elastic vibrating rod, which is installed in the vibrating feed pan, with the top of the vibrating rod extending into the center of the output end of the feed hopper assembly.

[0012] As a further improvement to the above solution, the bottom of the vibrating rod is fixed in the vibrating tray by a positioning component. The positioning component includes a rod concentrically arranged at the bottom of the vibrating rod. A cylinder is inserted into the bottom wall of the vibrating tray, and a block is inserted into the top of the cylinder. The top of the block has a slot for inserting the rod.

[0013] As a further improvement to the above solution, the feed hopper assembly includes a feed hopper body welded component. The top of the feed hopper body welded component is connected to the output end of the collecting hopper, and the bottom is connected to the inside of the vibrating material plate. The feed hopper body welded component has an upper pressure reducing plate and a lower pressure reducing plate with opposite inclination directions arranged sequentially on both sides from top to bottom.

[0014] As a further improvement to the above solution, the output end of the feed hopper is provided with an adjustment plate for adjusting the size of its output opening.

[0015] As a further improvement to the above solution, front and rear silicone rubber assemblies are respectively provided on both sides of the outer side of the output end of the feed hopper body welded part to block and buffer the material fed into the vibrating feed pan.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. The feeding device for lightweight and easily clogged materials of the present invention uses a vibrating component installed on a vibrating feed pan. The vibrating component is driven to vibrate at high frequency by the vibration generated by the vibrator assembly itself. This agitates the material accumulated after entering the feed hopper assembly from the collection hopper, causing it to passively overcome the resistance between materials and fall into the vibrating feed pan at an accelerated speed. The vibration of the vibrating feed pan then transports the material to the material chute, and finally through the identification and rejection sorting area.

[0018] 2. Without adding an extra drive, this invention makes reasonable use of existing structures and power to solve the problem of material blockage in the feed hopper for lightweight materials, ensuring smooth material conveying and sorting output. Attached Figure Description

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example 1

[0031] Please combine Figures 1 to 5 A feeding device for lightweight, easily clogged materials includes a base 1. A vibrator assembly 4 is elastically supported on the top of the base 1. A vibrating disc 6, connected to a material chute, is installed on the vibrating end of the top of the vibrator assembly 4. A feed hopper assembly 8, which can convey materials into the vibrating disc 6, is suspended above the vibrating disc 6 to receive the materials falling into the feed hopper assembly 8. A vibrating component is installed on the top of the vibrating disc 6, extending into the output end of the feed hopper assembly 8. The vibrating component can maintain synchronous vibration with the vibrating disc 6 to agitate the materials accumulated after entering the feed hopper assembly 8 from the collection hopper, so that the materials passively overcome the resistance between materials and fall more quickly into the vibrating disc 6.

[0032] The base 1 has four rubber pads 2 arranged in a rectangle on the top. The vibrator housing 41 of the vibrator assembly 4 is fitted with four rubber pads 2 at the bottom. A vibration isolation spring 3 is provided between two corresponding rubber pads 2.

[0033] In this embodiment, four sets of vibration isolation springs 3 are used. The entire vibrator assembly 4 and the vibrating feed pan 6 can be elastically supported by the rubber pads 2 on the base 1 and the vibration isolation springs 3.

[0034] The vibrator assembly includes a vibrator housing 41, a U-shaped plate 42, a gasket 43, a spring 44, a cover plate 45, and an internal coil core assembly 46. The vibrator housing 41 and the U-shaped plate 42 are connected by the spring 44 to form a whole. The top of the U-shaped plate 42 is fixedly connected to the bottom of the vibrating material tray 6. The internal coil core assembly 46 is enclosed and installed in the vibrator housing 41 through the cover plate 45.

[0035] The vibrator assembly also includes a gasket 43. The vibrator housing 41 and the U-shaped plate 42 are connected as one unit by the gasket 43, the spring 44 and the screws, so as to facilitate the disassembly, maintenance or replacement of the vibrator housing 41, the U-shaped plate 42 and the spring 44.

[0036] A fixed pressure plate 5 is provided on the vibrator housing 41, and a pressure plate 51 is provided on the top of the base 1. An adjusting screw (not shown) is inserted on the fixed pressure plate 5. The bottom thread of the adjusting screw passes through the pressure plate 51, and a nut (not shown) that matches the bottom of the adjusting screw is provided at the bottom of the pressure plate 51.

[0037] The compression of the vibration isolation spring 3 can be adjusted by using the adjusting screw on the fixed pressure plate 5 and the pressure plate 51.

[0038] The vibrating component is an elastic vibrating rod 7, which is installed in the vibrating feed pan 6, with the top of the vibrating rod 7 extending into the center of the output end of the feed hopper assembly 8.

[0039] The vibrating rod 7 utilizes the high-frequency vibration of the vibrator assembly 4 and the vibrating material plate 6 to create a large amplitude at its top, which agitates the material around the vibrating rod 7, causing it to overcome the resistance between the materials and fall into the lower vibrating material plate 6, and then be conveyed from the vibrating material plate 6 to the material chute.

[0040] In this embodiment, the vibrator 7 is made of a highly elastic material in order to generate a larger amplitude and more effectively move materials.

[0041] The feed hopper assembly 8 includes a feed hopper body weldment 81. The top of the feed hopper body weldment 81 is connected to the output end of the collecting hopper (not shown in the figure), and the bottom is connected to the inside of the vibrating feed pan 6.

[0042] Inside the feed hopper body welded component 81, from top to bottom, there are upper pressure reducing plate 82 and lower pressure reducing plate 83 with opposite inclination directions respectively. The upper pressure reducing plate 82 and lower pressure reducing plate 83 are both buffer structures for material falling, so that the material is decelerated and falls into the vibrating feed plate 6, ensuring that the material is fed evenly and smoothly.

[0043] The feed hopper body welded part 81 is provided with an adjustment plate 84 at the output end to adjust the size of its output end opening, so as to adjust the output amount of material through the output end of the feed hopper body welded part 81.

[0044] On both sides of the output end of the feed hopper body welded part 81, there are front silicone rubber assembly 85 and rear silicone rubber assembly 86, which can block and buffer the material fed into the vibrating feed pan 6. The front silicone rubber assembly 85 and rear silicone rubber assembly 86 are material blocking and buffering structures to prevent the material from escaping to the outside of the pan when it enters the vibrating feed pan 6, causing pollution and material waste.

[0045] In summary, the feeding method for lightweight, easily clogged materials in this embodiment includes the following steps:

[0046] (1) After the material falls from the collection hopper, it passes through the upper pressure reducing plate 82 and the lower pressure reducing plate 83 in the feed hopper body welded part 81 in sequence, and then falls into the vibrating material plate 6 from the lower opening of the feed hopper body welded part 81.

[0047] (2) The vibrating rod 7 vibrates at high frequency with the vibrator assembly 4 and the vibrating material plate 6, shaking the material accumulated in the feed hopper assembly 8, causing it to accelerate away from the opening at the bottom of the feed hopper body welded part 81.

[0048] (3) After the material falls into the vibrating feeder 6, it is vibrated and conveyed to the material chute;

[0049] (4) The material passes through the identification and rejection area from the slide to achieve sorting.

[0050] Example 2

[0051] Please combine Figures 6 to 8 This embodiment is an improvement on embodiment 1. The bottom of the vibrating rod 7 is fixed in the vibrating material tray 6 by the positioning component 9. The positioning component 9 includes an insertion rod 71 concentrically arranged at the bottom of the vibrating rod 7. A cylinder 901 is inserted into the bottom wall of the vibrating material tray 6. An insertion block 902 is inserted into the top of the cylinder 901. The top of the insertion block 902 has a slot 903 for the insertion rod 71 to be inserted.

[0052] Insert the rod 71 at the bottom of the vibrating rod 7 into the slot 903 and insert the plug 902 into the top of the cylinder 901 to achieve the initial installation and fixation of the vibrating rod 7 in the vibrating material plate 6.

[0053] Furthermore, a cylinder insertion groove 61 is provided on the bottom wall of the vibrating feed pan 6 for inserting the cylinder 901, and the cylinder 901 can rotate relative to the cylinder insertion groove 61 when it is inside the groove. The top of the cylinder 901 has an opening groove (not shown) for inserting the insertion block 902, and both the opening cross-section and the cross-section of the insertion block 902 are circular. A spiral groove 905 is provided along the axial direction of the opening groove, and a protrusion 904 is provided on the outer side of the insertion block 902 to slide and engage with the groove 905. A crossing (not shown) is provided at the opening of the opening groove to guide the protrusion 904 into the groove 905. A locking rod 906 that can extend out of the bottom of the cylinder 901 is concentrically slidably engaged, and a return spring (not shown) is provided between the top of the locking rod 906 and the inner wall of the cylinder 901.

[0054] When the insert block 902 is inserted into the cylinder 901, the protrusion 904 will slide and engage with the groove 905 through the cross passage. Driven by the continued axial downward movement of the insert block 902, the protrusion 904 rubs and squeezes the spiral groove wall of the groove 905, forcing the cylinder 901 to drive the locking rod 906 to rotate in one direction, so that the locking rod 906 rotates and engages in the locking groove 62, thereby completing the installation and fixation of the cylinder 901 on the vibrating material plate 6.

[0055] Furthermore, inside the insert block 902, two C-shaped swing arms 909 are arranged opposite each other via a coiled shaft 910 and a coiled spring. One end of each swing arm 909 is provided with a hook (not shown), and the outer wall of the insert rod 71 has a first slot 72 that engages with the hook. The other end of the swing arm 909 is provided with a pressure plate 911. A push rod 907 is elastically inserted into the bottom of the insert block 902 via a return spring. The bottom of the push rod 907 contacts and presses against the bottom wall of the opening slot (causing the return spring to compress and deform). The top of the push rod 907 is located inside the insert block 902 and is fixed with a cross arm 908. Both ends of the cross arm 908 are provided with rollers (not shown). The rollers contact and press against the corresponding pressure plates 911 to force the hooks of the swing arms 909 to deflect toward the first slot 72 (causing the coiled spring to compress and deform during this process).

[0056] Therefore, when the insert 902 enters the opening slot of the cylinder 901, the push rod 907 will be subjected to a reaction force when it touches the bottom of the opening slot, so as to force the push rod 907 to drive the horizontal arm 908 and the roller to move upward to squeeze the pressure plate 911 on both sides respectively, and force the two swing arms 909 to drive their respective hooks to close together, so as to respectively lock into the two first slots 72, thereby realizing the positioning and fixing of the vibrating rod 7 on the insert 902.

[0057] Furthermore, a locking ring 912 that can move axially relative to the outer side of the cylinder 901 is fitted. Two axially extending push rods 913 are arranged opposite each other on the annular surface of the locking ring 912 away from the vibrating material disc 6. Two vertical plates 914 are arranged opposite each other on the top of the insert block 902. A locking block 915 is slidably inserted into each of the two vertical plates 914. A second locking groove 73 is opened on the outer wall of the vibrating rod 7 to engage with one end of the locking block 915. An oblique through groove 916 is opened on the opposite end of the locking block 915, through which the push rod 913 can pass. After the top end of the push rod 913 contacts the groove wall of the oblique through groove 916, it slides and presses to force the locking block 915 to move toward the second locking groove 73 until the two are locked together. A washer (not marked) is fixed to the outside of the locking block 915. A return spring (not marked) is fitted on the outside of the locking block 915. The two ends of the return spring are connected to the washer and the upright plate 914 respectively. When the push rod 913 does not press the inclined through groove 916, the return spring does not deform.

[0058] The locking ring 912 drives the top rod 913 to move upward, so that the top rod 913 touches and penetrates the inclined through groove 916, forcing the locking block 915 to move towards the second locking groove 73 until the locking block 915 is engaged in the second locking groove 73, thereby further fixing the vibrating rod 7 on the insert block 902, and forming a whole between the vibrating rod 7, the insert block 902, the cylinder 901 and the vibrating material plate 6, so that the installation of the vibrating rod 7 on the vibrating material plate 6 is stable and reliable, and the disassembly and assembly are convenient for later maintenance or replacement.

[0059] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
