Description

Technical Field

[0001] This utility model belongs to the field of straw weaving technology, specifically, it relates to a straw bundling device for straw weaving. Background Technology

[0002] In the straw weaving industry, the uniform bundling of straw is a crucial step in ensuring weaving quality. Traditional straw bundling relies primarily on manual sorting, where workers separate bundles of straw into smaller bundles suitable for weaving. This method is common in small-scale workshops. With the development of the straw weaving industry, some companies have begun using simple mechanical bundling devices. These devices typically employ multi-layered screen structures or simple diversion plates for initial straw separation. Currently, manual bundling is labor-intensive and inefficient, making it difficult to meet the demands of large-scale production. Simple mechanical bundling devices, lacking proper guidance and separation structures, are prone to uneven distribution, tangling, or irregular bundle shapes during separation. Existing diversion plate devices often feature right-angled edges, causing straw to accumulate or break at the top of the diversion plate upon entering the diversion channel, affecting the continuity and integrity of the bundles. Furthermore, the discharge structure of existing devices is poorly designed, resulting in straw bundles of varying thicknesses from different outlets, failing to guarantee the uniformity required for subsequent weaving processes. Utility Model Content

[0003] In view of this, the present invention provides a straw bundling device for straw weaving, which can solve the technical problem of low straw weaving efficiency caused by uneven straw bundling in the prior art.

[0004] This utility model is implemented as follows:

[0005] This utility model provides a straw bundling device for straw weaving, comprising a bundling body having a bundling chamber, an inlet at the top of the bundling chamber, and multiple outlets at the bottom of the bundling chamber. A partition plate is provided inside the bundling chamber, extending downward from the inlet to the multiple outlets, dividing the bundling chamber into multiple independent channels, each channel corresponding to one outlet. The upper edge of the partition plate is arc-shaped, and the two sides of the partition plate are flat. The partition plate is fixedly connected to the inner wall of the bundling chamber by welding.

[0006] The technical effects of the straw bundling device for straw weaving provided by this utility model are as follows: By setting a partition plate, the material bundling chamber is divided into multiple independent channels, so that the straw entering from the inlet falls along their respective independent channels to the corresponding outlet under the action of gravity, thus achieving effective bundling of the straw. The upper edge of the partition plate is arc-shaped, which can guide the straw to enter each channel smoothly without accumulation. The two sides of the partition plate are flat, which ensures the regularity of the channels. The welding and fixing of the partition plate to the inner wall of the material bundling chamber ensures the stability of the partition plate during operation and avoids the partition plate from shifting position due to vibration or impact, which would affect the bundling effect.

[0007] Based on the above technical solution, the straw bundling device for straw weaving processing of this utility model can be further improved as follows:

[0008] The thickness of the partition plate gradually decreases from top to bottom along the vertical direction, and the thickness of the upper part of the partition plate is 2 to 3 times that of the lower part.

[0009] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the design of the partition plate thickness gradually decreasing from top to bottom makes the upper end have greater strength to withstand the initial impact force of the grass, while the lower end is thinner, which reduces the obstruction to the passage of grass. The thickness ratio of 2 to 3 times ensures both structural strength and optimizes the flowability of grass. This gradual thickness design makes the resistance encountered by grass gradually decrease during the falling process, improving the uniformity and smoothness of the bundle splitting.

[0010] Furthermore, the cross-sectional area of ​​the feed inlet is greater than the sum of the cross-sectional areas of all the discharge outlets, and a transition section is provided at the connection between the feed inlet and the distribution chamber, and the transition section is trumpet-shaped.

[0011] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the design that the cross-sectional area of ​​the feed inlet is greater than the sum of the cross-sectional areas of all the discharge outlets avoids the clogging of the feed inlet. The trumpet-shaped transition section makes the speed of the feed gradually decrease and evenly dispersed when the feed transitions from the feed inlet to the distribution chamber, reducing the direct impact of the feed on the partition plate. This structural design not only ensures the smoothness of feeding but also realizes the rational distribution of the feed to each channel, improving the overall working efficiency of the bundle splitting device.

[0012] Furthermore, the radius of the arc at the upper edge of the partition plate is 20mm~35mm, and the center of the arc is located on the center line of the thickness of the partition plate.

[0013] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the arc radius of the upper edge of the partition plate is set within the range of 20mm to 35mm, which can effectively guide the grass to slide into each independent channel along the arc surface, avoiding the grass from breaking or tangling at the top of the partition plate. The center of the arc is located on the thickness center line, which ensures that the arc surfaces on both sides are symmetrical, making the distribution of grass to the two side channels more uniform. This precise arc design reduces the mechanical damage of grass during diversion.

[0014] Furthermore, the discharge port is rectangular, with a spacing of 5mm to 10mm between two adjacent discharge ports, and the long side of the discharge port is parallel to the extension direction of the partition plate.

[0015] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the rectangular setting of the discharge port facilitates the output of hay in bundle form, and the spacing between adjacent discharge ports is 5mm~10mm, which not only ensures the independence of each bundle of hay but also avoids excessive weakening of the structural strength. The long side of the discharge port is parallel to the extension direction of the partition plate, so that the hay can be directly and smoothly discharged from the discharge port after falling along the channel. This discharge port arrangement ensures the neatness of the hay after being bundled.

[0016] Furthermore, the inner wall surface of the material distribution chamber is provided with multiple vertical ribs, which are evenly distributed along the circumference of the material distribution chamber, and the height of the vertical ribs is 2mm~4mm.

[0017] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the vertical ribs on the inner wall surface of the feeding chamber play a guiding role during the falling of the straw, preventing the straw from slipping or rotating on the smooth inner wall. The ribs are evenly distributed in the circumference to ensure that the guiding force on the straw in each channel is balanced. The rib height of 2mm to 4mm can effectively guide the straw without causing excessive obstruction, thus improving the stability of the straw falling in each channel.

[0018] Furthermore, a gap is formed between the lower end of the separator and the edge of the discharge port, with a height of 3mm to 6mm. This gap is used for the final separation of the forage.

[0019] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the 3mm~6mm gap between the lower end of the separator plate and the edge of the discharge port provides a buffer space for the final separation of the grass, avoiding the grass from being torn or stuck at the discharge port due to the separator plate extending directly to the discharge port. This gap allows the grass that has been basically separated into bundles to be completely separated into independent bundles before leaving the device, improving the thoroughness of bundle separation and the integrity of the grass.

[0020] Furthermore, the beam splitter body is made of stainless steel, and its outer surface is polished.

[0021] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: stainless steel material has good corrosion resistance and mechanical strength, and can withstand the friction and impact during the forage conveying process for a long time without deformation or damage. The outer surface polishing treatment makes the surface of the bundle body smooth, reducing the frictional resistance between the forage and the device surface. At the same time, the polished surface is not easy to adhere to forage debris, which facilitates cleaning and maintenance and extends the service life of the device.

[0022] Furthermore, the cross-section of the material distribution chamber is circular, and the partition plates are arranged radially, with 3 to 5 partition plates in total.

[0023] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the cross-section of the material distribution chamber is circular, which has high structural strength and no stress concentration points. The radial arrangement of the partition plates realizes the optimal use of space and makes the area of ​​each channel equal. The number of 3 to 5 partition plates can divide the grass into 4 to 6 bundles to meet the needs of conventional grass weaving. This arrangement makes the bundling device compact and the bundling effect uniform.

[0024] Furthermore, the edge of the feed inlet is provided with a flange structure, which extends outward to form a mounting flange. The mounting flange is provided with 4 to 6 mounting holes evenly distributed on it, which are used for bolt connection with external equipment.

[0025] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the mounting flange formed by the outward extension of the flange structure at the edge of the feed port provides a reliable mounting base for the connection between the device and external equipment; the 4 to 6 evenly distributed mounting holes ensure that the bolt connection is subjected to uniform force; this mounting structure design simplifies the installation process of the device, while ensuring the stability and sealing of the connection between the device and external equipment in the working state, and avoiding leakage of straw during the feeding process.

[0026] Compared with existing technologies, the beneficial effects of the straw bundling device for straw weaving provided by this utility model are as follows: By setting a partition plate extending downward from the inlet to multiple outlets within the bundling chamber, the bundling chamber is divided into multiple independent channels, allowing the straw to fall orderly along their respective channels under gravity, thus achieving directional bundling of the straw. The upper edge of the partition plate is arc-shaped, which guides the straw to flow smoothly from the inlet into each independent channel, avoiding the problems of straw accumulation and breakage caused by traditional right-angle edge designs. The welding and fixing of the partition plate to the inner wall of the bundling chamber ensures the positional stability of the partition plate during operation, eliminating channel deformation and uneven bundling caused by structural loosening. The independent outlet design for each channel ensures that each bundle of straw maintains an independent state and uniform bundle shape when leaving the device. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0034] like Figures 1-3 The image shows an embodiment of a straw bundling device for straw weaving provided by this utility model. In this embodiment, it includes a bundling body 10, which has a bundling chamber 11. The top of the bundling chamber is provided with an inlet 12, and the bottom of the bundling chamber is provided with multiple outlets 13. A partition plate 14 is provided inside the bundling chamber. The partition plate extends downward from the inlet to the multiple outlets, dividing the bundling chamber into multiple independent channels. Each channel corresponds to one outlet. The upper edge of the partition plate is arc-shaped, and the two sides of the partition plate are flat. The partition plate is fixedly connected to the inner wall of the bundling chamber by welding.

[0035] In the above technical solution, the thickness of the partition plate gradually decreases from top to bottom along the vertical direction, and the thickness of the upper part of the partition plate is 2 to 3 times the thickness of the lower part.

[0037] Furthermore, in the above technical solution, the arc radius of the upper edge of the partition plate is 20mm~35mm, and the center of the arc is located on the thickness center line of the partition plate.

[0038] Furthermore, in the above technical solution, the discharge port is rectangular, the distance between two adjacent discharge ports is 5mm~10mm, and the long side of the discharge port is parallel to the extension direction of the partition plate.

[0039] Furthermore, in the above technical solution, the inner wall surface of the material distribution cavity is provided with multiple vertical ribs 16, which are evenly distributed along the circumference of the material distribution cavity, and the height of the vertical ribs is 2mm~4mm.

[0040] Furthermore, in the above technical solution, a gap is formed between the lower end of the separator plate and the edge of the discharge port, with a gap height of 3mm to 6mm, and the gap is used for the final separation of the forage.

[0041] Furthermore, in the above technical solution, the beam splitter body is made of stainless steel, and the outer surface of the beam splitter body is polished.

[0042] Furthermore, in the above technical solution, the cross-section of the material distribution chamber is circular, the partition plates are arranged radially, and the number of partition plates is 3 to 5.

[0043] Furthermore, in the above technical solution, the edge of the feed inlet is provided with a flange structure 17, which extends outward to form a mounting flange 18. The mounting flange is provided with 4 to 6 mounting holes 19 evenly, which are used for bolt connection with external equipment.

[0044] The method of using this utility model is as follows: The bundle-splitting body is bolted to the discharge end of the external feeding device through the mounting holes on the mounting flange, ensuring a tight, gapless connection between the inlet and the discharge outlet of the feeding device. After starting the feeding device, the bundled hay is conveyed to the inlet through the feeding device. Under the action of gravity, the hay enters the transition section through the inlet. The funnel-shaped structure of the transition section gradually reduces the falling speed of the hay and spreads it evenly in all directions. After the hay comes into contact with the arc-shaped upper edge of the partition plate, it slides into the independent channels formed by the partition plate under the guidance of the arc-shaped surface. During the vertical fall of the hay in the independent channels, it is constrained by the space of the two sides of the partition plate to maintain its bundle shape. At the same time, the vertical ribs on the inner wall of the distribution chamber guide the hay and prevent it from rotating or sliding against the wall in the channel. When the hay falls to the gap between the lower end of the partition plate and the discharge outlet, the gap space provides a buffer for the final separation of the hay, so that each bundle of hay is completely separated into an independent state before leaving the device. The straw is ultimately output in uniform bundles through its corresponding outlets. The output bundles are of consistent thickness and regular shape, meeting the requirements of subsequent straw weaving processes. The entire bundling process is continuous and requires no manual intervention. The bundled straw can be directly fed into the weaving equipment for processing.

[0045] The following is a specific embodiment 1: A straw weaving processing enterprise uses the straw bundling device of this utility model. The bundling body is made of stainless steel, and the diameter of the bundling chamber is 100mm and the height is 250mm. The diameter of the inlet is 75mm, and the cone angle of the transition section is 38° and the height is 25mm. There are 5 rectangular outlets at the bottom of the bundling chamber, each outlet measuring 20mm × 10mm, with a spacing of 7mm between adjacent outlets. There are 5 partition plates evenly distributed radially inside the bundling chamber, dividing the bundling chamber into 5 independent channels. The upper edge of the partition plate is machined into an arc shape with a radius of 28mm, and the thickness of the partition plate is 5mm at the top and 2.5mm at the bottom, decreasing linearly. The partition plates are fully welded to the inner wall of the bundling chamber using argon arc welding. A 4.5mm gap is maintained between the lower end of the partition plate and the upper edge of the outlet. Ten vertical ribs are evenly distributed along the axial direction on the inner wall of the bundling chamber, with a height of 3mm and a width of 4mm. The feed inlet has an outward-extending mounting flange with an outer diameter of 140mm and a thickness of 4mm. Five evenly spaced 8mm diameter mounting holes are provided on the flange for bolt connections. This device is installed on the company's hay conveying production line, with the feeding equipment delivering hay at a rate of 15kg~20kg per minute. After passing through the transition section into the distribution chamber, the hay is evenly distributed into five independent channels under the guidance and separation of the partition plates. Vertical ribs stabilize and guide the falling hay, preventing it from swaying within the channels. The hay undergoes thorough bundling and sorting as it falls through the 250mm high channels, reaching the lower gap of the partition plates where each bundle is completely separated. Five bundles of hay are simultaneously output from the five outlets, each bundle having a uniform and stable diameter within the range of 8mm~10mm, with a neat bundle shape and no tangling or scattering. The output hay bundles directly enter five parallel hay weaving machines for weaving, with a smooth weaving process without material breaks or blockages. The straw bundling device can operate continuously for 8 hours without failure, processing a total of 800-900 kg of straw. The stainless steel construction and polished surface of the device ensure smooth flow of straw within the channels. After operation, a small amount of straw debris can be easily removed by blowing with an air gun, making maintenance convenient. This device effectively solves the problems of high labor intensity in manual straw bundling and uneven bundling in simple bundling devices, significantly improving the production efficiency and product quality stability of straw weaving.

[0046] The following is a specific embodiment 2: This embodiment is an improvement on embodiment 1, changing the thickness gradient of the separator plate from a linear decrease to a parabolic decrease. This results in a rapid thinning of the separator plate in the upper third and a gradual thinning in the lower two-thirds. This improvement gives the upper part of the separator plate a stronger load-bearing capacity, capable of withstanding the larger impact force of the initial fall of the forage, while the gradual thinning at the lower end reduces resistance and allows for smoother flow of the forage in the lower part of the channel. Simultaneously, the cross-sectional shape of the vertical ribs is changed from rectangular to triangular, with the rib tips pointing towards the center of the distribution chamber. The triangular ribs have a height of 3mm and a base width of 5mm. The triangular ribs provide a gentler guiding effect on the forage, reducing resistance when the forage contacts the ribs. Furthermore, the triangular structure is less prone to accumulating forage debris, facilitating cleaning. The device using this improved design performs better when processing fresh forage with high moisture content, increasing the forage's falling speed in the channel by approximately 15%, and further improving the uniformity and stability of the bundle separation effect.

[0047] The following is a specific embodiment 3: This embodiment is another improvement based on embodiment 1. A ring-shaped guide channel is added at the middle height of the distributing chamber. The guide channel is 5mm wide and 3mm deep, and is integrally formed with the inner wall of the distributing chamber. The function of the guide channel is to provide a brief buffer and sorting space during the falling of the forage, allowing the faster-falling forage to pause slightly at the guide channel position, keeping it synchronized with the slower-falling forage, and improving the consistency of the falling forage in each channel. At the same time, the shape of the discharge port is changed from rectangular to trapezoidal with a narrower top and a wider bottom. The upper width of the trapezoid is 10mm, the lower width is 15mm, and the height is 20mm. The trapezoidal discharge port design causes the forage to be slightly compressed laterally when passing through the discharge port, resulting in a more compact and neat bundle of output forage. The device using this improved design is particularly suitable for processing mixed straw with large differences in length. The buffering effect of the guide channel and the shaping effect of the trapezoidal outlet together ensure the consistency of the output straw bundles, meeting the needs of fine straw weaving processes with higher requirements for straw bundle quality.

[0048] Specifically, the principle of this invention is as follows: A partition plate divides the material distribution chamber into multiple independent channels, achieving physical isolation of the forage in space and preventing mutual interference and entanglement between different bundles of forage. The continuous design of the partition plate extending from the inlet to the outlet ensures that the forage is always subject to clear spatial constraints throughout its descent, guaranteeing the consistency of the bundles. The arc-shaped edge design at the upper end of the partition plate follows the streamline principle in fluid mechanics, reducing the impact force and resistance when the forage contacts the partition plate, allowing the forage to enter each channel smoothly. The welded fixation of the partition plate to the inner wall of the material distribution chamber provides reliable structural strength, enabling the device to withstand the impact load of the forage during continuous operation. The independent outlet ensures that each bundle of forage does not affect the others during output, maintaining the stability of the bundle distribution effect. This structural design transforms the complex forage bundling process into simple spatial separation and gravity guidance, ensuring the uniformity and reliability of the bundle distribution.
