Description

Technical Field

[0001] This utility model relates to the field of dicalcium phosphate processing technology, specifically to a dicalcium phosphate powder packaging and conveying line. Background Technology

[0002] After processing, dicalcium phosphate is typically stored temporarily in storage tanks, then packaged into bags using a packing line. After being sealed with thread, it is transferred to external transport equipment or storage warehouses via conveyor. Currently, during the dicalcium phosphate packaging process, each packing line is generally equipped with one packing device and one sewing device, along with a corresponding conveyor for transfer.

[0003] In actual production, the packaging process, including bagging and sewing, takes time. To reduce the number of conveyors, lower overall costs, and minimize subsequent transfer waiting time, multiple packaging lines typically share a single conveyor. This means the conveyor has multiple inputs and shares a single output. The multiple inputs and outputs are usually connected by a steering mechanism. For example, patent CN200710003169.2 describes a conveyor device that uses a switching unit to connect the straight section and branch sections, or patent CN202323501201.3 describes a conveyor device that uses a turning mechanism to connect the upstream and downstream conveyor lines. While these existing designs are suitable for lightweight, small-sized materials with low spatial requirements, they are clearly unsuitable for bagged dicalcium phosphate weighing 100-200 catties and initially in an upright position. Meanwhile, bagged dicalcium phosphate in an upright position is prone to varying degrees of tilting or even collapsing, which hinders the conveyor's outward transport and affects subsequent transportation and palletizing operations. To address this, workers typically use specialized equipment on the upstream conveyor line to knock down the bagged dicalcium phosphate before conveying it to a switching mechanism. This mechanism then transfers the bagged dicalcium phosphate from the upstream to the downstream conveyor line. Clearly, this structural design not only adds the need for knocking equipment but also requires the existing switching mechanism to cooperate, increasing overall equipment and control costs, as well as subsequent maintenance costs. Utility Model Content

[0004] In order to overcome one of the shortcomings of the existing technology, the purpose of this utility model is to provide a dicalcium phosphate powder packaging and conveying line. This dicalcium phosphate powder packaging and conveying line has a simple structure and can properly lay down the material while transferring the material to the next stage conveyor belt.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] A dicalcium phosphate powder packaging and conveying line includes several upstream and downstream conveying lines. Each upstream conveying line is equipped with a filling and packaging machine and a bag sewing machine sequentially along the conveying direction. The downstream conveying line is set at an angle to all the upstream conveying lines. A tipping device is provided between each upstream and downstream conveying line. The inlet end of each tipping device is connected to the output end of the corresponding upstream conveying line, and the outlet end of each tipping device is mounted above the downstream conveying line. The outlet end of each tipping device is inclinedly connected to a correction slide. The tipping device can tip the material along the sliding direction of the correction slide. The material in the correction slide can slide onto the downstream conveying line. The horizontal projection of the sliding direction of the material in the correction slide overlaps with the horizontal projection of the downstream conveying line.

[0007] Furthermore, each of the aforementioned tilting devices includes a frame and a receiving conveyor line mounted on the frame. The inlet end of the receiving conveyor line is connected to the output end of the corresponding upstream conveyor line, and the output end of the receiving conveyor line is mounted above the downstream conveyor line. The correcting slide is mounted on the side of the frame corresponding to the output end of the receiving conveyor line, and a tilting mechanism is mounted on the side of the frame opposite to the correcting slide. The tilting mechanism can push the upright material on the receiving conveyor line into the correcting slide.

[0008] Furthermore, the pushing mechanism includes a pushing frame and a pushing cylinder. The top two sides of the pushing frame are hinged to the frame. The mounting end of the pushing cylinder is hinged to the frame. The telescopic end of the pushing cylinder is hinged to one swinging end of the pushing frame. The pushing cylinder can push the pushing frame to swing and push the bottom of the material on the conveyor line to slide into the corrective slide first.

[0009] Furthermore, a limiting roller is rotatably provided above the inlet end of the correction slide on the frame, and a feed inlet is formed between the limiting roller and the inlet end of the correction slide. The pushing mechanism can push the material standing upright on the conveyor line from the feed inlet into the correction slide.

[0010] Furthermore, guard plates are provided on both sides of the corrective slide, the lower end of the corrective slide is mounted above the downstream conveyor line, and guard plates are also provided on both sides of the corresponding area of ​​the lower end of the corrective slide of the downstream conveyor line.

[0011] Furthermore, a position sensor is provided on one side of the pusher frame or machine frame located at the output end of the conveyor line, and the position sensor is electrically connected to the pusher cylinder.

[0012] Furthermore, the lower end of the pusher frame is rotatably equipped with several rollers.

[0013] Furthermore, guardrails are installed on both sides of the upstream conveyor line.

[0014] Furthermore, the upstream conveyor line is composed of two independent sections connected together, with the filling and packaging machine located on the first section of the upstream conveyor line and the bag sewing machine located on the second section of the upstream conveyor line.

[0015] Furthermore, the downstream conveyor line includes a lifting section and a horizontal conveyor section, the horizontal conveyor section being connected to all of the lowering devices.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model discloses a dicalcium phosphate powder packaging and conveying line. Based on existing multi-conveyor lines, a tipping device is designed. This device tipps down the material from the upstream conveyor line and pushes it into a corrective chute. This ensures the material's spatial orientation during downstream conveying, facilitating subsequent stacking. Simultaneously, the tipping device is located above the downstream conveyor line, thus avoiding interference with its normal transport flow and ensuring that multiple upstream conveyors can independently transport materials to the downstream line. The corrective chute maintains the preset spatial orientation of the tipped material, facilitating its transfer to the downstream conveyor line. The horizontal projection of the corrective chute overlaps with the horizontal projection of the downstream conveyor line, ensuring that the material's orientation remains unchanged during transfer from the corrective chute to the downstream conveyor line, minimizing spatial orientation changes and further facilitating subsequent stacking.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0032] Reference Figures 1 to 4 The illustrated dicalcium phosphate powder packaging and conveying line includes several upstream conveying lines 10 and downstream conveying lines 40. Each upstream conveying line 10 is equipped with a filling and packaging machine 20 and a bag sewing machine 30 sequentially along the conveying direction. The downstream conveying lines 40 are arranged at an angle to all the upstream conveying lines 10. A tipping device 50 is provided between each upstream conveying line 10 and the downstream conveying line 40. The inlet end of each tipping device 50 is connected to the output end of the corresponding upstream conveying line 10, and the outlet end of each tipping device 50 is mounted above the downstream conveying line 40. Each outlet end of the tipping device 50 is inclinedly connected to a correction slide 60. The tipping device 50 can tip the material along the sliding direction of the correction slide 60. The material in the correction slide 60 can slide onto the downstream conveying line 40. The horizontal projection of the sliding direction of the material in the correction slide 60 overlaps with the horizontal projection of the downstream conveying line 40.

[0033] In this application, both the upstream conveyor line 10 and the downstream conveyor line 40 are designed as belt conveyors, supported by several support rollers to achieve heavy-duty conveying. This design is a conventional conveying structure and will not be detailed here. The upstream conveyor line 10 and the downstream conveyor line 40 are designed vertically, facilitating connection between them. The groove structure of the corrective slide 60 has an inverted trapezoidal cross-section, allowing the bagged dicalcium phosphate to automatically maintain a specific posture during sliding as it is transferred to the downstream conveyor line 40. In this application, the corrective slide 60 can only accommodate one bag of dicalcium phosphate at a time, and its sides also provide spatial posture limitation for the bagged dicalcium phosphate.

[0034] It should be noted that both the filling and packaging machine 20 and the bag sewing machine 30 are conventional packaging equipment in this application. For example, both the filling and packaging machine 20 and the bag sewing machine 30 can adopt the filling mechanism and sewing mechanism in CN217456692U - a packaging bag filling and sewing production line. The filling and packaging machine 20 can also adopt the technical solution in patent CN 218086109U - a fully automatic phosphate fertilizer packaging machine, which will not be described in detail here.

[0035] See Figure 1 and Figure 4 In the above embodiments, guardrails 11 are provided on both sides of the upstream conveyor line 10 to prevent the upright bags of dicalcium phosphate from tipping over. To accommodate different operational needs, the upstream conveyor line 10 is composed of two independent sections connected together. The filling and packaging machine 20 is located on the first section of the upstream conveyor line 10, and the bag-sewing machine 30 is located on the second section of the upstream conveyor line 10, thus adapting to the conveying speed requirements of both the bag-sewing machine 30 and the filling and packaging machine 20. Furthermore, in the above embodiments, the downstream conveyor line 40 includes a lifting section 41 and a horizontal conveying section 42, with the horizontal conveying section 42 connected to all the tipping devices 50. The main purpose of the lifting section 41 is to facilitate the subsequent transfer of the bagged dicalcium phosphate to vehicles or for palletizing.

[0036] This dicalcium phosphate powder packaging and conveying line incorporates a tilting device 50 based on existing multi-conveyor lines. The tilting device 50 tilts the material from the upstream conveyor line 10, which is in an upright position, and pushes it into the corrective chute 60. This ensures that the downstream conveyor line 40 maintains the spatial orientation of the material during transport, facilitating subsequent stacking. Simultaneously, the tilting device 50 is located above the downstream conveyor line 40, thus avoiding interference with its normal transport flow and ensuring that multiple upstream conveyor lines 10 can independently transport materials to the downstream conveyor line 40. The corrective chute 60 ensures that the tilted material maintains a preset spatial orientation, facilitating its transfer to the downstream conveyor line 40. The horizontal projection of the corrective chute 60 overlaps with the horizontal projection of the downstream conveyor line 40, ensuring that the material's orientation remains unchanged and its spatial orientation is minimally altered when transferred from the corrective chute 60 to the downstream conveyor line 40, further benefiting subsequent stacking.

[0037] See Figures 1 to 4 To facilitate the direct pushing and sliding of bagged dicalcium phosphate into the corrective chute 60, each of the tipping devices 50 includes a frame 51 and a receiving conveyor line 52 mounted on the frame 51. The inlet end of the receiving conveyor line 52 is connected to the output end of the corresponding upstream conveyor line 10, and the output end of the receiving conveyor line 52 is mounted above the downstream conveyor line 40. The corrective chute 60 is located on the side of the frame 51 corresponding to the output end of the receiving conveyor line 52. A tipping mechanism is provided on the side of the frame 51 opposite to the corrective chute 60, which can push the upright material on the receiving conveyor line 52 into the corrective chute 60.

[0038] Specifically, in the above embodiment, the conveying speed of bagged dicalcium phosphate is reduced by receiving the conveyor line 52, and the pushing action of the overturning mechanism is adapted to make the upright bagged dicalcium phosphate tilt in the preset falling direction, which helps to ensure the spatial posture of the bagged dicalcium phosphate on the downstream conveyor line 40.

[0039] In the above embodiments, conventional methods of pushing over bagged dicalcium phosphate involve large movements, and the direction of the bagged dicalcium phosphate's collapse is difficult to control, which is detrimental to the conveying of the downstream conveyor line 40. Therefore, in one embodiment of this application, the pushing mechanism includes a pusher frame 53 and a pusher cylinder 54. The top two sides of the pusher frame 53 are hinged to the frame 51, and the mounting end of the pusher cylinder 54 is hinged to the frame 51. The telescopic end of the pusher cylinder 54 is hinged to the swinging end of the pusher frame 53. The pusher cylinder 54 can push the pusher frame 53 to swing and slide the bottom of the material on the conveyor line 52 into the correction chute 60 first. In this application, the pusher frame 53 is designed to facilitate swinging and pushing of bagged dicalcium phosphate to the maximum area. At the same time, the bagged dicalcium phosphate is first pushed into the correction slide 60 by its bottom. At this time, the upper end of the bagged dicalcium phosphate will fall to one side of the pusher frame 53. In this way, when the bagged dicalcium phosphate falls, it can fit into the inclined correction slide 60, reducing the overall amount of swing in space. The upper end of the fallen bagged dicalcium phosphate swings at a lower speed and the amount of swing is reduced, which is more conducive to maintaining the spatial posture of the bagged dicalcium phosphate within the correction slide 60.

[0040] In the above embodiments, to facilitate the control of the actuation time of the push cylinder 54 and to adapt to the conveying action of the receiving conveyor line 52, in one embodiment of this application, a position sensor 56 is provided on one side of the push frame 53 or the frame 51 located at the output end of the receiving conveyor line 52. The position sensor 56 is electrically connected to the push cylinder 54. In fact, the control system between the position sensor 56 and the push cylinder 54 is a conventional electronic control system, and the technical solution in patent CN201980080593.8 - Method for Controlling Cylinders can be referred to, which will not be described in detail here.

[0041] In the above embodiment, when the bottom of the bagged dicalcium phosphate is slid into the inlet of the corrective slide 60, the entire bag of dicalcium phosphate may slide down rapidly. At this time, because the center of gravity of the entire bag of dicalcium phosphate is unstable, and with the pushing action of the pusher 53, the entire bag of dicalcium phosphate may also tilt in the opposite direction, that is, tilt towards one side of the corrective slide 60. In order to avoid the above situation, the frame 51 is rotatably provided with a limiting roller 55 above the inlet of the corrective slide 60. The limiting roller 55 and the inlet of the corrective slide 60 form a feed port. The pushing mechanism can push the material standing upright on the conveyor line 52 from the feed port into the corrective slide 60. The actual position of the limiting roller 55 relative to the receiving conveyor line 52 in the vertical direction is about half the height of the bagged dicalcium phosphate when it is upright. This can prevent the upper end of the bagged dicalcium phosphate from falling towards the correcting slide 60. At the same time, the design of the inlet can also flatten the bagged dicalcium phosphate when it falls towards the pusher 53. That is, the space between the limiting roller 55 and the inlet end of the correcting slide 60 is used to flatten and straighten the shape of the packaging bag, which is convenient for the later stacking work.

[0042] In the above-mentioned improved scheme, in order to prevent the bagged dicalcium phosphate from sliding out of the corrective slide 60 and from sliding out when it falls onto the downstream conveyor line 40, guard plates 70 are provided on both sides of the corrective slide 60. The lower end of the corrective slide 60 is mounted above the downstream conveyor line 40, and guard plates 70 are also provided on both sides of the corresponding area of ​​the downstream conveyor line 40 located at the lower end of the corrective slide 60.

[0043] See Figure 4 In the improved embodiment described above, in order to better enable the lower end of the pusher 53 to slide relative to the surface of the bagged dicalcium phosphate, a plurality of rollers 57 are rolledly installed on the lower end of the pusher 53, wherein the outer diameter of the rollers 57 protrudes from the side of the pusher 53 that is in contact with the surface of the bagged dicalcium phosphate.

[0044] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
