Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, specifically a device for quantitative conveying of viscous materials, which is particularly suitable for applications in the food, chemical, and pharmaceutical industries where high-viscosity materials need to be accurately measured and continuously conveyed. Background Technology

[0002] In industrial production, the conveying of viscous materials is a common and complex problem. Traditional methods often fail to achieve precise control and continuous conveying of such materials, especially in scenarios requiring quantitative output, which can easily lead to problems such as material blockage and uneven conveying.

In this device, a sealing wheel is mounted on an auxiliary drive shaft, and a conveying wheel is mounted on a main drive shaft. The sealing wheel and conveying wheel are located within the conveying chamber of the pump body and sealed by a pump cover. The sealing wheel and conveying wheel mesh with each other. A main drive gear is mounted on the main drive shaft, and a driven gear is mounted on the auxiliary drive shaft. The main drive gear and driven gear mesh with each other. The motor main shaft is directly connected to the main drive shaft via a coupling. This invention enables quantitative conveying of highly viscous materials; reduces device noise and improves pump efficiency; the conveying wheel and sealing wheel are designed as a two-toothed rotor wheel and a two-grooved rotor wheel, respectively. This structural form is simple, reduces tooth wear, and facilitates cleaning and maintenance; it also allows for lower requirements on the impurity content of the conveyed medium, especially the solid particle content; and the conveying pump has high volumetric efficiency.

[0004] However, the aforementioned patented technology has a complex structure and is inconvenient to operate. Moreover, this device cannot meet the needs of rapid industrial conveying of viscous materials. Therefore, it is particularly important to develop a device that can effectively solve the above problems and achieve stable and quantitative conveying of viscous materials. Utility Model Content

[0005] The purpose of this invention is to provide a quantitative conveying device for viscous materials to solve the problems mentioned in the background art.

[0006] (1) How to achieve efficient and accurate conveying of viscous materials while ensuring the continuity and stability of the conveying process.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A quantitative conveying device for viscous materials;

[0009] Includes a housing, drive shaft, two turntables, and several shovel assemblies;

[0010] The outer shell has a storage chamber, a discharge port extending from the front of the outer shell and communicating with the outside, and a feed port extending from the rear of the outer shell and communicating with the outside. The drive shaft passes through the outer shell along the axial direction of the outer shell and is supported on the side walls at both ends of the outer shell. Two turntables are fixedly installed on the drive shaft at intervals. The two turntables are located in the storage chamber of the outer shell, and there is a gap between the two turntables and the side wall of the storage chamber.

[0011] Several shovel assemblies are evenly distributed circumferentially between two turntables along the axial direction of the drive shaft. Each shovel assembly includes a bucket, two half-shafts, two connecting rods, and two positioning blocks. The two half-shafts are fixedly connected to the left and right sides of the bucket, respectively. The two connecting rods are arranged on the left and right sides of the bucket, respectively. One end of each connecting rod is hinged to the edge of the corresponding turntable, and the other end is hinged to the corresponding half-shaft. The positioning block is fixedly connected to the end of the corresponding half-shaft. The positioning block can move along the gap between the corresponding turntable and the side wall of the storage chamber. The bucket moves circumferentially along the drive shaft, and the movement trajectory of the bucket passes through the discharge port and the inlet of the outer shell, respectively.

[0012] Based on the above technical solution, the present invention can be further improved as follows.

[0013] Furthermore, the outer shell includes an upper shell and a lower shell. The lower end face of the upper shell is open, the upper end face of the lower shell is open, and a storage chamber is formed between the upper shell and the lower shell. The opening area of ​​the upper shell extending out of the lower shell forms a discharge port, and the opening area of ​​the lower shell extending out of the upper shell forms a feed port.

[0014] Furthermore, rails are fixedly connected to the inner walls of the storage chamber on both sides inside the lower shell. The rails on both sides correspond one-to-one with the two positioning blocks of the shovel assembly. The rails are only for the positioning blocks to pass through.

[0015] Furthermore, the trajectory of the bucket moving from the bottom of the storage chamber to a position near the discharge port is the shoveling stroke.

[0016] Furthermore, it also includes two tilting discs, which correspond one-to-one with two turntables. The tilting discs are fixedly connected to the inner wall of the storage chamber. The ends of the tilting discs extend outward from the turntables. A tilting groove is opened on the lower end face of the tilting disc. The beginning of the tilting groove and the track at the end of the shoveling stroke have a smooth transition. The positioning block of the shoveling assembly can continue to move along the upper side wall of the tilting groove. A through groove is opened on the upper end face of the tilting disc and the lower end of the through groove communicates with the tilting groove. The through groove is only for the positioning block of the shoveling assembly to pass through.

[0017] Furthermore, the turntable has several limiting slots at its edge, which can cooperate with the half shafts of several shovel assemblies.

[0018] Furthermore, the drive shaft is supported by bearings on the left and right end sidewalls of the housing, and the end of the drive shaft is connected to an external power output source.

[0019] Furthermore, a support is provided on the lower side of the outer casing.

[0020] With this structure, the outer shell consists of an upper shell and a lower shell, which are joined together at their open ends to form a storage chamber, which is roughly circumferential in shape. The front opening of the upper shell forms the discharge port, and the rear opening of the lower shell forms the inlet port, facilitating the entry and exit of materials.

[0021] The drive shaft runs through the housing axially and is supported on the left and right sides of the housing by bearings. One end of the shaft is connected to an external power source to drive the entire device.

[0022] Two turntables are fixedly mounted on the drive shaft at intervals within the material storage chamber, maintaining a certain gap with the chamber sidewalls to reduce friction and allow the material shoveling assembly to pass through. Multiple limiting slots are provided on the edges of the turntables to engage with the half-shafts of the material shoveling assembly, ensuring accurate entry of the half-shafts into the track for precise control of the bucket's movement position and ensuring the accuracy of the material shoveled each time.

[0023] The shoveling assemblies are evenly distributed circumferentially between the two turntables along the axis of the drive shaft. Each shoveling assembly includes a bucket, two half-shafts, two connecting rods, and two positioning blocks. The bucket is connected to the connecting rods via the half-shafts, and the other end of the connecting rods is hinged to the edge of the turntable, forming a linkage mechanism that allows the bucket to move along a specific trajectory when the turntable rotates. The positioning blocks are fixed to the ends of the half-shafts and reciprocate along the gap between the turntable and the side wall of the chamber, ensuring that the bucket accurately performs shoveling and feeding actions.

[0024] The tipping disc is fixedly installed on the inner wall of the storage chamber, located at the end of the shoveling stroke. The tipping disc is equipped with a tipping trough and a through trough. The tipping trough smoothly transitions to the end of the shoveling stroke, guiding the material in the bucket to tip over and fall into the next stage of the conveying path; the through trough is only for the positioning block to pass through, so as to avoid interfering with the material flow.

[0025] The beneficial effects of this quantitative conveying device for viscous materials are:

[0026] (1) Precise quantification: Through the coordinated action of the turntable, shovel assembly and tipping disc, precise quantification and continuous conveying of viscous materials are achieved.

[0027] (2) High efficiency and stability: The four-bar linkage design makes the bucket move smoothly, reduces the risk of material blockage, and improves the conveying efficiency.

[0028] (3) Strong adaptability: It is suitable for conveying a variety of viscous materials. Adjusting the turntable speed and the parameters of the shovel assembly can meet different production needs.

[0029] (4) Easy maintenance: The structure is reasonably designed and easy to disassemble and clean, which reduces maintenance costs.

[0030] (5) Protecting materials: The bucket can scrape materials along the inner wall of the storage chamber. The bucket and other components will not squeeze the materials, which can ensure the integrity of the particles in the materials. Attached Figure Description

[0042] Please see Figures 1 to 6 .

[0043] This quantitative conveying device for viscous materials includes a housing 100, a drive shaft 200, two turntables 300, two tipping discs 500, and multiple sets of shovel assemblies.

[0044] The outer shell 100 includes an upper shell 110 and a lower shell 120. The lower end face of the upper shell 110 is open, and the upper end face of the lower shell 120 is open. The upper shell 110 and the lower shell 120 form a storage chamber 130, which is generally circumferential in shape. The opening area of ​​the front part of the upper shell 110 extending out of the front part of the lower shell 120 forms a discharge port 140, and the opening area of ​​the rear part of the lower shell 120 extending out of the rear part of the upper shell 110 forms a feed port 150. A bracket 600 is welded and fixed to the bottom of the lower shell 120.

[0045] The drive shaft 200 passes through the housing 100 along the axial direction of the housing 100, and the drive shaft 200 is supported by bearings on the left and right end sidewalls of the housing 100. The end of the drive shaft 200 is connected to an external power output source.

[0046] Two turntables 300 are fixedly mounted on the drive shaft 200 at intervals. The two turntables 300 are located inside the storage chamber 130 of the outer casing 100, and there is a gap between the two turntables 300 and the side wall of the storage chamber 130. Multiple limiting slots 310 are opened at the edge of the turntables 300, and the multiple limiting slots 310 can cooperate with the half shafts 420 of multiple shovel assemblies.

[0047] Multiple sets of shovel assemblies are evenly distributed circumferentially between two turntables 300 along the axial direction of the drive shaft 200 (only four sets of shovel assemblies are shown in this embodiment to clearly show the structure of the shovel assemblies). Each shovel assembly includes a bucket 410, two half-shafts 420, two connecting rods 430, and two positioning blocks 440. The two half-shafts 420, two connecting rods 430, two turntables 300, and two positioning blocks 440 correspond one-to-one. The two half-shafts 420 are fixedly connected to the left and right sides of the bucket 410, respectively. The two connecting rods 430 are arranged on the left and right sides of the bucket 410, respectively. One end of the connecting rod 430 is hinged to the edge of the corresponding turntable 300, and the other end of the connecting rod 430 is hinged to the corresponding half-shaft 420. The positioning block 440 is fixedly connected to the end of the corresponding half-shaft 420. The positioning block 440 can move along the gap between the corresponding turntable 300 and the side wall of the storage chamber 130.

[0048] Tracks 121 are bolted to the inner walls of the storage chamber 130 inside the lower housing 120. The two tracks correspond one-to-one with the two positioning blocks 440 of the shovel assembly. The tracks 121 are only for the positioning blocks 440 to pass through.

[0049] The bucket 410 of the shoveling assembly moves in a circular motion along the drive shaft 200, and the movement trajectory of the bucket 410 passes through the discharge port 140 and the feed port 150 respectively. During this process, when the positioning block 440 enters the upper housing 110, the positioning block 440 can move along the gap between the turntable 300 and the side wall of the storage chamber 130; when the positioning block 440 enters the lower housing 120, the positioning block 440 can move along the track 121 of the lower housing 120. The trajectory of the bucket 410 moving from the bottom of the track 121 to a position near the discharge port 140 is the shoveling stroke.

[0050] Two tilting discs 500 correspond one-to-one with two turntables 300. The tilting discs 500 are fixedly connected to the inner wall of the storage chamber 130. The tilting discs 500 are at the end of the shoveling stroke. The end of the tilting discs 500 extends out of the turntables 300. A tilting groove 510 is opened on the lower end face of the tilting discs 500. The beginning of the tilting groove 510 and the end of the shoveling stroke have a smooth transition. The positioning block 440 of the shoveling assembly can continue to move along the upper side wall of the tilting groove 510. A through groove 520 is opened on the upper end face of the tilting groove 510 and the tilting discs 500. The lower end of the through groove 520 communicates with the tilting groove 510. The through groove 520 is only for the positioning block 440 of the shoveling assembly to pass through.

[0051] In operation, when the drive shaft 200 is driven to rotate by an external geared motor, the turntable 300 rotates accordingly, driving the bucket 410 to move along a predetermined trajectory via the connecting rod 430 mechanism. The bucket 410 scoops up material from the bottom of the storage chamber 130 and moves along the trajectory to the vicinity of the discharge port 140 to complete the unloading. At the end of the scooping stroke, the tilting disc 500 flips the material through the tilting trough 510, ensuring that the material smoothly enters the next stage of processing or conveying. The cooperation between the positioning block 440 and the limit slot 310 ensures precise control of the amount of material scooped each time.

[0052] The above description is only one embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the principle of the present utility model, and these should also be considered to fall within the protection scope of the present utility model.
