Description

Technical Field

[0001] This invention relates to the field of storage auxiliary device technology, and more specifically to a reciprocating uniform fabric distribution mechanism. Background Technology

[0002] After the dry-mixed mortar is mixed, if it cannot be packaged immediately, it usually needs to be transferred to a designated silo for storage in order to free up the mixing equipment and prevent the dry-mixed mortar from getting damp or contaminated. The usual method is to use a lifting device to throw the mixed dry-mixed mortar to the top of the silo, and then use a material distribution device on the top of the silo to distribute the dry-mixed mortar into the silo.

[0003] However, most current cloth-laying devices are simply circular rotating cloth-laying devices. During the cloth-laying process, gaps or material piles are easily formed in the area corresponding to the center of the rotation. Under the influence of different specific gravities of dry-mixed mortar materials, coarse and fine separation is likely to occur, which in turn leads to uneven dry-mixed mortar mix ratio in this area, thus affecting important properties of subsequent products such as strength and consistency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes a reciprocating uniform material distribution mechanism to solve the technical problems of uneven material distribution and the tendency for material accumulation or blank areas to appear at specific points in existing technologies.

[0005] The technical solution adopted in this invention is a reciprocating fabric equalization mechanism, comprising: The hopper has an inlet and an outlet at its upper and lower ends, respectively. A fabric-laying mechanism, wherein the fabric-laying mechanism is located inside the hopper and connected to the feed inlet; The fabric feeding mechanism includes: a fabric feeding nozzle, a drive assembly, and a guide rail assembly. The fabric feeding nozzle is rotatably connected to the feed inlet. The drive assembly is located on the upper side of the hopper and is drively connected to the fabric feeding nozzle so that it can rotate around the output axis. The guide rail assembly is located inside the hopper and is connected to the fabric feeding nozzle. The fabric nozzle can swing as it rotates, guided by the guide rail assembly.

[0006] This structure, through the cooperation of the guide rail assembly and the material dispensing nozzle, enables the mortar to be distributed more evenly when the mixed dry mortar is loaded into the silo for storage, reducing the dispersion that may occur due to the different volumes of raw materials in the mortar, and improving the storage uniformity of dry mortar.

[0007] The fabric nozzle includes a connecting cylinder and a guide plate. The connecting cylinder is concentrically distributed with the feed inlet and is rotatably disposed within the hopper. The diameter of the connecting cylinder is larger than the diameter of the feed inlet. The drive assembly is connected to the connecting cylinder in a transmission manner. The number of guide plates is at least two, and they are symmetrically hinged to the lower opening of the connecting cylinder.

[0008] This structure, through the drive component driving the connecting cylinder, enables the guide plate to move circumferentially around the axis of the feed inlet. Combined with the guiding effect of the guide rail assembly on the guide plate, it allows the mortar material to be distributed more evenly and over a wider area into the hopper, improving the uniformity of the mortar mix ratio.

[0009] An anti-overflow cloth is provided between the two guide plates, and the anti-overflow cloth is provided on both sides of the guide plates to cover the side openings formed when the two guide plates are installed.

[0010] This structure can block the opening between the two guide plates, preventing mortar from overflowing from the opening during the fabric application process and improving the accuracy of the fabric guidance.

[0011] The guide rail assembly includes a track and a traction device. The track is fixed in the hopper by a bracket, and its horizontal height matches the horizontal height of the guide plate. The number of traction devices is the same as that of the guide plate and they are connected one-to-one. When the guide plate rotates, it can drive the traction device to slide along the track and apply a radial thrust relative to the feed inlet to the guide plate through the traction device and the guide rail.

[0012] The horizontal cross-section of the track has a closed rhombus profile, including a first tip and a second tip arranged opposite to each other. The radial distance from the first tip to the center of the track is greater than the radial distance from the second tip to the center of the track. The center of the track coincides with the center of the feed inlet.

[0013] This structure, through the cooperation of guide rails and traction devices, allows the guide plates to move around the feed inlet while being guided by the structure of the guide rails and pulled or pushed by the traction devices, thereby causing the two guide plates to flip in the same direction at the same time, thus automatically adjusting the material guiding direction of the guide plates.

[0014] The traction device includes a slide, a connecting rod, and a ball head. The slide is slidably connected to the middle of the guide plate, and the sliding direction is parallel to the axis of the feed inlet. One end of the connecting rod is hinged to the slide, and the ball head is connected to the other end of the connecting rod and slidably connected to the track.

[0015] This structure is stable and simple, and can meet the structural changes during the connection of the guide plate and guide rail and the tilting and swinging.

[0016] The lower ends of the two guide plates are connected to a material guide bag, and the feeding channel of the material guide bag is connected to the channel of the fabric nozzle.

[0017] This structure, through the setting of the guide bag, can provide secondary guidance and buffering for the mortar material entering the hopper, reduce the free fall height of the mortar material during the falling process, thereby reducing the unevenness of the mix caused by different falling speeds due to different weights, and also reduce the amount of dust generated during the material distribution process.

[0018] Two winding components are centrally symmetrically arranged between the guide plate and the material guide bag. The winding components are used to wind up the drooping part of the material guide bag.

[0019] The winding assembly includes a support plate, a winding roller, a first motor, and a traction cable. The support plate is fixedly connected to the side of the guide plate. The first motor is located on the upper side of the guide plate, and its rotating shaft is concentrically connected to the winding roller. One end of the traction cable is connected to the winding roller, and the other end slides through the support plate and is connected to the guide bag.

[0020] This structure, through the drive of the first motor to the winding roller, and the drive of the winding roller to the traction cable, thereby adjusting the discharge height of the guide bag, can match the changes in the storage height of mortar in the silo and prevent the guide bag from being blocked or buried.

[0021] The number of traction cables is multiple and of varying lengths. They are connected to the take-up roller via a ratchet clutch in order of increasing length. Except for the shortest traction cable, the ends of the other traction cables are provided with spring boxes that are connected to the guide bag. The spring boxes are used to take up the redundant parts of the traction cables. In the order of length, the length of the longer traction cable is more than three times that of the shorter traction cable.

[0022] This structure, with multiple traction cables of varying lengths, combined with the ratchet clutch and the split winding effect of the coil spring box, can gradually wind up the guide bag, thus avoiding the possibility of folding caused by directly traction on the lower part of the guide bag and reducing material blockage.

[0023] As can be seen from the above technical solution, the beneficial technical effects of the present invention are as follows: 1. Through the cooperation of the feeding nozzle and the guide rail assembly, when the driving component drives the feeding nozzle to move in a circular motion around the feed inlet, the guide rail assembly can simultaneously guide and traction the guide plate to swing synchronously, so as to distribute the mortar material into the hopper more evenly and improve the uniformity of the material distribution.

[0024] 2. By setting up the material guide bag, the mortar material can be further guided and buffered during the material guiding process. On the one hand, this reduces the uneven distribution of the mortar material due to different falling speeds caused by different component weights. On the other hand, it can reduce the amount of dust during material distribution.

[0025] 3. By setting up the winding component, the discharge height of the guide bag can be further adjusted according to the amount of mortar stored in the hopper, which is more conducive to the material needs.

[0026] 4. By setting up multiple traction cables of different lengths, and coordinating with the automatic transmission or idling of the ratchet clutch, as well as the redundant winding of the traction cable by the coil spring box, the multiple traction cables can be wound in stages to form a progressive winding of the guide bag, thereby reducing the possibility of blockage caused by bending due to folding of the guide bag.

[0029] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0030] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by those skilled in the art to which this invention pertains.

[0031] Example 1: like Figure 1-3 As shown, this embodiment provides a reciprocating equalization material distribution mechanism, including: a hopper 1 and a material distribution mechanism 2; the hopper 1 is provided with an inlet 11 and an outlet 12 at its upper and lower ends, respectively; the material distribution mechanism 2 is located inside the hopper 1 and connected to the inlet 11; the material distribution mechanism 2 includes: a material distribution nozzle 21, a drive assembly 22 and a guide rail assembly 23, the material distribution nozzle 21 is rotatably connected to the inlet 11, the drive assembly 22 is located on the upper side of the hopper 1 and is drively connected to the material distribution nozzle 21 so that it can rotate around the axis of the outlet 12, the guide rail assembly 23 is located inside the hopper 1 and connected to the material distribution nozzle 21; when rotating, the material distribution nozzle 21 is guided by the guide rail assembly 23 and can form a sway.

[0032] The working principle of Example 1 is explained in detail below: During the material feeding process, the feed inlet 11 on the hopper 1 is used to input the dry-mixed mortar material after mixing, and the discharge outlet 12 is used to connect with the external packaging machine for subsequent packaging. Before loading the mortar material into the hopper 1, the drive assembly 22 is activated to synchronously drive the feeding nozzle 21 to rotate around the axis of the feed inlet 11. With the guidance of the guide rail assembly 23, the feeding nozzle 21 will be swayed while rotating circumferentially around the axis of the feed inlet 11, due to the traction of the guide rail assembly 23. At this time, the mortar material flows from the feed inlet... When the material is fed into the feeding nozzle 21, it will be guided by the movement of the feeding nozzle 21 to disperse the mortar material into the hopper 1, thereby achieving the effect of dispersed reciprocating feeding. Compared with the conventional method of only rotating the feeding port in a circular motion, this feeding method makes the mortar material more uniform when stored in the hopper 1, reduces the accumulation of material at the center of the hopper 1, and keeps the relative position of the feeding mechanism 2 centered, improving the stability of equipment operation, reducing the frequency of failures and reducing the difficulty of maintenance, while significantly improving the uniformity of mortar material distribution.

[0033] The feeding nozzle 21 includes a connecting cylinder 211 and a guide plate 212. The connecting cylinder 211 is concentrically distributed with the feed inlet 11 and is rotatably disposed in the hopper 1. The diameter of the connecting cylinder 211 is larger than the diameter of the feed inlet 11. The drive assembly 22 is connected to the connecting cylinder 211 in a transmission manner. There are at least two guide plates 212, which are symmetrically hinged to the lower opening of the connecting cylinder 211.

[0034] In this first embodiment, the connecting cylinder 211 is mainly used to connect the feed inlet 11 and cooperate with the drive component 22 to rotate, so as to drive the guide plate 212 to rotate around the feed inlet 11. In this way, the guide rail assembly 23 can cyclically adjust the angle and orientation of the guide plate 212 to meet the needs of dispersing and distributing the material.

[0035] In this embodiment, the drive assembly 22 consists of a second motor 221 and a pulley assembly 222. The second motor 221 is fixedly mounted on the upper end of the hopper 1 for maintenance, heat dissipation, and observation. The pulley assembly 222 is located between the connecting cylinder 211 and the output shaft of the second motor 221. Through the pulley connected to the shaft of the second motor 221, the pulley ring located on the outside of the connecting cylinder 211, and the transmission belt wound between the pulley and the pulley ring, the connecting cylinder 211 can be rotated by the drive of the second motor 221, thereby driving the entire fabric nozzle 21 to move. In other embodiments, the drive assembly 22 can also be a direct drive such as a gear.

[0036] An anti-overflow cloth 213 is provided between the two guide plates 212. The anti-overflow cloth 213 is provided on both sides of the guide plate 212 and can cover the side openings formed when the two guide plates 212 are installed.

[0037] In this first embodiment, the anti-overflow cloth 213 is mainly used to cover the side openings of the two guide plates 212 to prevent the mortar material in the connecting cylinder 211 from overflowing from the side openings between the two guide plates 212 when guided by the cloth, thus affecting the uniformity of the cloth. At the same time, the anti-overflow cloth 213 itself is made of a stretchable material such as cloth, so it does not affect the change of the angle position of the two guide plates 212 when they swing.

[0038] Furthermore, a dustproof cloth is provided between the hopper 1 and the two guide plates 212, located on the lower side of the guide rail assembly 23. The dustproof cloth is used to separate the upper and lower spaces of the hopper 1.

[0039] In this first embodiment, the dustproof cloth is also made of a material with inherent elasticity, such as cloth, or other materials with better airtightness, such as rubber diaphragms. This can isolate the guide rail assembly 23 entirely inside the upper side of the hopper 1 to avoid the dust or mortar generated during the material distribution process from affecting the guide rail assembly 23, reducing the equipment failure rate and lowering the maintenance frequency. Of course, in order to ensure the stability of the air pressure inside the hopper 1 due to volume changes during the material distribution process, a corresponding air passage pipe can be set between the dustproof cloth and the upper end of the hopper 1 to discharge the air inside the hopper 1 to meet the storage needs.

[0040] The guide rail assembly 23 includes a track 231 and a traction device 232. The track 231 is fixed in the hopper 1 by a bracket, and its horizontal height matches the horizontal height of the guide plate 212. The number of traction devices 232 is the same as that of the guide plate 212 and they are connected one by one. When the guide plate 212 rotates, it can drive the traction device 232 to slide along the track 231, and apply a radial thrust relative to the feed inlet 11 to the guide plate 212 through the traction device 232 and the guide rail.

[0041] The horizontal cross section of the track 231 has a closed rhomboid profile, including a first tip 2311 and a second tip 2321 arranged opposite to each other. The radial distance from the first tip 2311 to the center of the track 231 is greater than the radial distance from the second tip 2321 to the center of the track 231. The center of the track 231 coincides with the center of the feed inlet 11.

[0042] In this first embodiment, the traction device 232 is directly connected to the guide plate 212 and can move synchronously with the guide plate 212 during its circumferential rotation. Combined with the positional traction of the traction device 232 by the track 231, the traction device 232 and the track 231 work together to push or pull the guide plate 212. The horizontal cross-sectional shape of the track 231 is a closed rhombus profile with two apexes. When the two opposing guide plates 212 move the traction device 232 along the track 231, they can form a continuous connection through the rhombus structure of the track 231. The continuous and cyclical traction action means that, according to the change in the moving position of the traction device 232 in the first tip 2311 and the second tip 2321, a corresponding thrust or traction force is applied to the guide plate 212, and the forces on the two guide plates 212 are opposite. Therefore, the angle position of the two guide plates 212 can be adjusted in the same direction at the same time to change the direction and position of the guide plate 212 in guiding the mortar material distribution. This allows the swaying to be formed synchronously while the entire distribution nozzle 21 is moving in a circle, thereby further dispersing and expanding the distribution area, which is more conducive to the need for uniform material distribution.

[0043] The traction device 232 includes a slide block 2321, a connecting rod 2322, and a ball head 2323. The slide block 2321 is slidably connected to the middle part of the guide plate 212, and the sliding direction is parallel to the axis of the feed inlet 11. One end of the connecting rod 2322 is hinged to the slide block 2321, and the ball head 2323 is connected to the other end of the connecting rod 2322 and slidably connected to the track 231.

[0044] In this first embodiment, the connecting rod 2322 can slide up and down along the middle of the guide plate 212 via the slide block 2321. The ball head 2323 connects to the connecting rod 2322. When the connecting rod 2322 rotates with the guide plate 212, its circumferential position changes, and its relative position to the guide plate 212 also changes. This causes the slide block 2321 to push the guide plate 212 to flip, and the slide block 2321 to slide along the middle of the guide plate 212. This allows a stable guiding connection to be formed between the guide plate 212 and the traction device 232. By controlling the position of the traction device 232 relative to the track 231, the guide plate 212 is repeatedly driven to deflect and guide the material during the cyclical motion, thus meeting the needs of continuous material feeding.

[0045] Example 2: like Figure 4 As shown, the only difference in technical features compared to Embodiment 1 is that the lower ends of the two guide plates 212 are connected to the material guide bag 3, and the feeding channel of the material guide bag 3 is connected to the channel of the material nozzle 21.

[0046] Apart from that, all other structures are identical.

[0047] In this second embodiment, the guide bag 3 has a cylindrical structure and is connected to the discharge side of the cloth nozzle 21. When the mortar is output from the cloth nozzle 21, the mortar will be guided down by the guide bag 3. On the one hand, this can reduce the segregation caused by the different falling speeds of the components with different weights in the mortar. On the other hand, it can reduce the amount of dust during cloth feeding, which is more conducive to the cloth feeding needs of mortar.

[0048] Example 3: like Figure 5 As shown, the only difference in technical features compared to Embodiment 2 is that two winding components 4 are provided symmetrically between the guide plate 212 and the material guide bag 3. The winding components 4 are used to wind up the drooping part of the material guide bag 3.

[0049] The winding assembly 4 includes: a support plate 41, a winding roller 42, a first motor 43, and a traction cable 44. The support plate 41 is fixedly connected to the side of the guide plate 212. The first motor 43 is located on the upper side of the guide plate 212, and its rotating shaft is concentrically connected to the winding roller 42. One end of the traction cable 44 is connected to the winding roller 42, and the other end slides through the support plate 41 and is connected to the guide bag 3.

[0050] Apart from that, all other structures are identical.

[0051] In this third embodiment, to prevent the mortar material in the hopper 1 from gradually blocking or burying the guide bag 3, and to ensure that the guide bag 3 is always kept at the optimal guiding height, during the feeding process, the first motor 43 on the support plate 41 feeds the material synchronously to wind up the take-up roller 42, so that the traction cable 44 gradually wraps around the take-up roller 42. At this time, the traction cable 44 will synchronously lift the guide bag 3 upward, so that the outlet height of the guide bag 3 can be increased to match the continuously rising mortar material level. At the same time, since the guide bag 3 itself is made of cloth and has a certain degree of folding flexibility, the lifted guide bag 3 will not affect the guiding of the material.

[0052] In other embodiments, the material guide bag 3 may also be fitted with a folded corrugated tube on the outside, and a counterweight ring may be provided at the lower opening of the material guide bag 3 to further improve the smooth flow of material guide space after the material guide bag 3 is lifted and reduce folding obstruction.

[0053] The wiring of the first motor 43 can be achieved by setting an electric slip ring at the connecting cylinder 211 to meet the wiring requirements of the first motor 43 in the rotating state. This is a well-known common knowledge technology in circuit wiring, so it will not be elaborated on here.

[0054] Example 4: like Figure 5-6 As shown, the only technical feature that differs from Embodiment 3 is that there are multiple traction cables 44 of varying lengths, which are connected to the take-up roller 42 via a ratchet clutch in order of increasing length. Except for the shortest traction cable 44, the ends of the other traction cables 44 are provided with spring boxes 5 that are connected to the guide bag 3. The spring boxes 5 are used to take up the redundant parts of the traction cables 44. In the order of length, the length of the longer traction cable 44 is more than three times that of the shorter traction cable 44.

[0055] Apart from that, all other structures are identical.

[0056] In this fourth embodiment, to maximize the matching of the material storage height of the hopper 1 and avoid directly connecting the traction cable 44 to its lower opening for winding the guide bag 3, multiple traction cables 44 of unequal lengths are connected to the winding roller 42 when winding the guide bag 3. Since the traction cables 44 are of unequal lengths, and except for the shortest traction cable 44, the ends of the remaining traction cables 44 are equipped with spring boxes 5, when the winding roller 42 winds up, the shortest traction cable 44 will be wound up first. The shortest traction cable 44 is wound up, and the corresponding shortest traction cable 44 is connected to the guide bag 3 at a higher horizontal position. Therefore, the upper side of the guide bag 3 will be lifted and folded first, thereby increasing the discharge height of the lower end of the guide bag 3. During this process, due to the weight of the guide bag 3 and the presence of the counterweight ring, the lower guide bag 3 will keep the bag body flat, and only the upper guide bag 3 will be folded and wound up. This can significantly reduce the folding area, thereby reducing the phenomenon of mortar blockage and clumping.

[0057] Correspondingly, when the shortest traction cable 44 is fully wound up and the guide bag 3 is fully wound up, due to the ratchet clutch, in this embodiment the winding roller 42 is the active rotating part, the active end of the ratchet clutch is fixedly connected to the winding roller 42, and the driven end is connected to the traction cable 44. When the traction cable 44 is not fully wound, the ratchet clutch engages, and the winding roller 42 drives the traction cable 44 to wind synchronously. When a single traction cable 44 is wound to its limit position, the driven end stops due to resistance, the winding roller 42 rotates continuously at low speed, the ratchet clutch overruns and idles, and the traction cable 44 stops winding, while the remaining traction cables 44 continue to complete the winding action.

[0058] The ratchet clutch structure is a well-known technology, and will only be explained in principle here, without further details.

[0059] This allows for the gradual winding and folding of the guide bag 3 within a smaller space, based on the length of the traction cable 44 and in conjunction with the coil spring box 5 to wind up the redundant length of the longer traction cable 44, which is more conducive to the fabric needs.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
