Description

Technical Field

[0001] The invention relates to the technical field of silicon core tubes, in particular to a flexible tensile-resistant silicon core tube and a closing device. Background Art

[0002] During the loading, unloading and transportation of silicon-core tubes, strapping tape is an important tool for fixing and protecting the tubes. Its stability and reliability are crucial to the overall safety of the tubes. However, in actual operation, due to the characteristics of the material and structural design of the strapping tape itself, as well as improper operation during loading, unloading and transportation, the strapping tape is often easily gathered together, causing the entire coil to become loose and deformed. This not only affects the appearance quality of the tube, but more importantly, it may have an adverse effect on the physical properties and service life of the tube. At the same time, when silicon-core tubes are transported over long distances, due to the bumps and vibrations during vehicle driving, relative displacement and friction will occur between the tubes and between the tubes and the strapping tape. This long-term, repeated friction and impact will cause the strapping tape to gradually become loose, or even pull off or break. Once the strapping tape fails, the entire coil of tubes is prone to skew or scatter.

[0003] The patent with authorization announcement number CN205229529U discloses a corrosion-resistant HDPE silicon core tube, which is provided with an antibacterial layer inside, so that the inside of the silicon core tube will not be corroded by microorganisms after a long time, thereby increasing the service life of materials such as optical cables arranged inside the silicon core tube; in addition, an anti-radiation layer is provided in the middle of the silicon core tube to block the radiation emitted by radioactive materials such as optical cables, thereby reducing the harm of radiation to the human body and reducing mutual interference of radiation.

[0004] However, this technical solution still has some defects: the silicon core tube has enhanced corrosion resistance by adding an antibacterial layer and an anti-radiation layer, but it cannot increase the strength of the silicon core tube itself, and cannot improve the compression and bending resistance. Especially when the silicon core tube is packaged, the silicon core tube is prone to tearing, and after the silicon core tube is packaged into bundles, the silicon core tube is prone to impact the packaging tape, causing the packaging tape to loosen or break.

DETAILED DESCRIPTION

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0040] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0041] Example 1

[0042] This is the first embodiment of the present invention, which provides a flexible tensile-resistant silicon core tube.

[0043] Reference Figure 1 and Figure 2Specifically, it includes a silicon core tube body 1, an anti-friction silicon core layer 2 is arranged on the outside of the silicon core tube body 1, a high-density polyethylene material layer 3 is arranged on the outside of the anti-friction silicon core layer 2, a color ribbon layer 4 is arranged on the outside of the high-density polyethylene material layer 3, and an outer sheath 5 is arranged on the outside of the color ribbon layer 4. The outer sheath 5 is made of transparent silica gel material, which has high elasticity and significantly improves the environmental stress cracking resistance of the flexible tensile silicon core tube, and at the same time has good resistance to corrosion from chemical substances such as acids and alkalis.

[0044] The anti-friction silicon core layer 2 is used to improve the wear resistance and sliding property of the silicon core tube body 1 ; the high-density polyethylene material layer 3 is used to enhance the strength and durability of the overall structure of the silicon core tube body 1 .

[0045] The anti-friction silicon core layer 2 serves as an inner layer, which effectively prevents direct contact between the internal medium and the external environment, while reducing the friction loss of the pipe during use and extending its service life; the anti-friction silicon core layer 2 is mainly composed of high-performance silicone rubber material, which incorporates wear-resistant microparticles of silicon carbide and lubricant silicone oil, which not only retains the original excellent properties of silicone rubber, such as weather resistance, high and low temperature resistance, chemical stability, etc., but also enhances its wear resistance and self-lubrication. The addition of lubricant forms a lubricating film on the surface of the anti-friction silicon core layer 2, which reduces the friction coefficient between the pipe and other contact surfaces, improves sliding properties, reduces heat and wear generated by friction, and further protects the internal structure and external coating of the pipe.

[0046] The high-density polyethylene material layer 3 is made by an extrusion process, which significantly enhances the compressive strength and tensile strength of the pipe and improves the overall structural stability of the pipe; the ribbon layer 4 is formed by an extrusion process and is used to identify pipeline information or distinguish pipelines of different uses; the outer sheath 5 also uses a highly active adsorption material to ensure that it will not react with any substance, thereby enhancing the mechanical strength of the outer layer. The outer sheath 5 is used to protect the internal structure of the silicon-core tube body 1 and observe the internal situation, so that the pipe can quickly return to its original use size after being extruded and deformed.

[0047] The outer wall array of the ribbon layer 4 is provided with a plurality of grooves 41, and the inner wall array of the outer sheath 5 is provided with a plurality of ridges 51. The ends of the ridges 51 extend to the inner walls of the grooves 41 and fit tightly therewith. The connection stability between the outer sheath 5 and the ribbon layer 4 is further improved through the concave-convex matching structure. The interior of the ridges 51 is provided with reinforcing ribs 52. The reinforcing ribs 52 are corrugated and are used to enhance the strength and toughness of the ridges 51. The reinforcing ribs 52 are used to improve the compression and bending resistance of the outer sheath 5.

[0048] The combination of HDPE high-density polyethylene base pipe and silicon core layer is tighter and more reliable, which can improve its service life and increase its wear resistance.

[0049] In the raw material stage, the raw materials are mixed, preheated and evenly mixed through a hopper dryer to remove moisture from the raw materials. The vacuum feeder then feeds the materials to ensure that the feeding is uniform and stable without any breakage. At the same time, the feeding is precisely controlled to control the weight per meter and wall thickness of the product.

[0050] Customized molds are used in the silicon core tube molding stage to ensure molding pressure and further plasticize the material. The mold, die and mandrel are all electroplated with mirror finish to ensure smooth inner and outer walls of the tube from the source, greatly improve the performance of the tube and reduce the friction coefficient of the inner wall of the tube.

[0051] Afterwards, a high-level water tank is installed to eliminate the bubbles in the vacuum forming box, stabilize the vacuum, cool and shape the silicon-core tube, and use a suitable sizing sleeve to make the tube look bright and have uniform and stable size. A four-claw traction machine is used with strong traction force and multi-point clamping to prevent the product from deformation. Hydraulic adjustment control is used to clamp tubes with an outer diameter of 32-150mm.

[0052] The silicon core pipe is tested, air is supplied by air compressor, steel ball is tested, and the variable diameter plug is used to prevent the pipe from leaking, so as to ensure that the whole roll of pipe is not blocked and leaking, which is convenient for cable threading and cable blowing construction. This series of processes together constitutes the complete production chain of flexible tensile silicon core pipe from raw materials to finished products, meeting the market's strict requirements for the tear resistance and other differentiated needs of pipes.

The servo motor 104 drives the rotating shaft 201 to rotate inside the limit bearing 1021 through a wheel chain. The fixed shaft 202 passes through the winding assembly 200, and the end position of the fixed shaft 202 is located inside the shell 101.

A part of the rotating shaft 201 extends into the interior of the shell 101 and passes through the limit bearing 1021 above the internal fixed platform 102. A transmission gear 2011 is fixed on the outer side of the end of the rotating shaft 201. The servo motor 104 under the placement table 103 drives the transmission gear 2011 to rotate through the wheel chain, and the rotation of the transmission gear 2011 will drive the rotating shaft 201 to rotate.

[0061] The sleeve 2012 is fixed on the other side of the rotating shaft 201, located outside the shell 101, and is driven by the transmission gear 2011 located inside the shell 101 to rotate outside the shell 101. A plurality of movement grooves 2013 are arranged in an array on the outer surface of the sleeve 2012. The fixed rod 2014 is fixed inside the sleeve 2012, close to one side of the shell 101. There are a plurality of fixed rods 2014 in an array, which extend from the movement grooves 2013 on the surface of the sleeve 2012 to the outside, and cooperate with the limit rod 204 on the outside of the fixed shaft 202 to limit the rolled silicon core tube and limit the length after bundling.

[0063] A portion of the fixed shaft 202 extends into the housing 101 , and is longer than the length of the rotating shaft 201 inside the housing 101 . The fixed shaft 202 is located at the axis of the rotating shaft 201 , and the rotation of the rotating shaft 201 and the fixed shaft 202 do not affect each other.

[0064] The first drive shaft 2021 is sleeved on the outside of the fixed shaft 202, and the two move synchronously. The length of the first drive shaft 2021 is shorter than that of the fixed shaft 202, and there is a certain distance between the front end of the first drive shaft 2021 and the front end of the fixed shaft 202.

Two first push columns 2023 are symmetrically arranged on the outside of the end of the shell 101.

[0066] Among them, the second drive shaft 2024 is sleeved on the outside of the first drive shaft 2021, and the length of the second drive shaft 2024 is shorter than that of the first drive shaft 2021. The short length is the same as the difference in length between the front end of the first drive shaft 2021 and the fixed shaft 202. A second push ring 2025 is fixed to the outside of the front end of the second drive shaft 2024. The end position of the second drive shaft 2024 extends to the interior of the shell 101. A threaded groove 2026 is opened at the end position of the second drive shaft 2024. The first push column 2023 on the outside of the first drive shaft 2021 rotates inside the threaded groove 2026. When the threaded groove 2026 rotates, the first drive shaft 2021 will be driven to slide inside the second drive shaft 2024 through the sliding of the first push column 2023 inside the threaded groove 2026.

[0067] Better, refer to Figure 8 The second driving shaft 2024 is sleeved with a third driving shaft 2028 on the outside, and the outer wall of the end of the third driving shaft 2028 is sleeved with a third pushing ring 2029, the outer wall of the third driving shaft 2028 is sleeved with a fourth driving shaft 20210, and the outer wall of the end of the fourth driving shaft 20210 is sleeved with a fourth pushing ring 20211, and the outer wall of the fourth driving shaft 20210 is sleeved with an output shaft 20212, and the outer wall of the output shaft 20212 is provided with a driving groove 20213, and the end of the output shaft 20212 is also provided with an output gear 20214.

[0068] In which, similarly, the third drive shaft 2028 is sleeved on the outside of the second drive shaft 2024, and the fourth drive shaft 20210 is sleeved on the outside of the third drive shaft 2028, and the ends of both extend into the interior of the shell 101, and the third drive shaft 2028 is connected to the third push column, and the third push column at the end of the third drive shaft 2028 slides in the thread groove 2026 at the end of the second drive shaft 2024, and the fourth drive shaft 20210 is connected to the fourth push column, and the fourth push column at the end of the fourth drive shaft 20210 slides in the thread groove 2026 at the end of the third drive shaft 2028, thereby driving the second drive shaft 2024 to slide inside the third drive shaft 2028, and the third drive shaft 2028 to slide inside the fourth drive shaft 20210.

[0069] The output shaft 20212 is sleeved on the outside of the fourth drive shaft 20210, and the fourth push column outside the fourth drive shaft 20210 slides inside the drive groove 20213 on the surface of the output shaft 20212.

When the transmission gear 2011 rotates, the rotating shaft 201 rotates along with the transmission gear 2011. The rotation drives the sleeve 2012 on the other side of the rotating shaft 201 to rotate on the outside of the shell 101.

The rotating shaft 201 is sleeved on the outside of the fourth drive shaft 20210, and the rotating shaft 201 and the fourth drive shaft 20210 do not affect each other. At the same time, the length difference between the first drive shaft 2021 and the front end of the fixed shaft 202 is the same as the length difference between the first drive shaft 2021 and the second drive shaft 2024, the length difference between the second drive shaft 2024 and the third drive shaft 2028 is the same as the length difference between the first drive shaft 2021 and the second drive shaft 2024. Similarly, the length difference between the third drive shaft 2028 and the fourth drive shaft 20210 is the same.

[0072] The first push column 2023 at the end of the first drive shaft 2021 slides inside the thread groove 2026 at the end of the second drive shaft 2024, and the second push column 2027 at the end of the second drive shaft 2024 slides inside the thread groove 2026 at the end of the third drive shaft 2028. Similarly, the third push column at the end of the third drive shaft 2028 slides inside the thread groove 2026 at the end of the fourth drive shaft 20210, and the fourth push column at the end of the fourth drive shaft 20210 slides inside the drive groove 20213 at the end of the external output shaft 20212.

[0073] When the driving motor 105 drives the output shaft 20212 to rotate, the output shaft 20212 rotates outside the fourth driving shaft 20210. The output shaft 20212 is restricted to rotate without displacement. When the output shaft 20212 rotates, the driving groove 20213 on the surface rotates to drive the fourth push column at the end of the fourth driving shaft 20210 to slide inside the driving groove 20213. When the fourth push column slides inside the driving groove 20213, it drives the fourth driving shaft 20210 to slide forward inside the output shaft 20212. When the fourth push column slides to At the bottom of the driving groove 20213, the rotation of the output shaft 20212 will begin to drive the fourth driving shaft 20210 to rotate together. At the same time, as the fourth driving shaft 20210 rotates, the third pushing column on the outer wall of the third driving shaft 2028 begins to slide inside the thread groove 2026 at the end of the fourth driving shaft 20210. When sliding to the bottom of the thread groove 2026, the rotation of the fourth driving shaft 20210 begins to drive the third driving shaft 2028 to rotate, step by step, until the first driving shaft 2021 slides forward inside the second driving shaft 2024.

[0074] Example 3

[0075] This is the third embodiment of the present invention, which is implemented based on the previous embodiment.

[0076] Specifically, refer to Fig. 9 A protrusion 2031 is provided on the outer wall of the winding plate 203, a notch 2032 is provided on the outer wall of the winding plate 203 away from the protrusion 2031, a slide plate 2033 is provided on one side of the end face of the winding plate 203, and a hinge block 2034 is provided on the outer wall on the other side away from the slide plate 2033.

[0077] There are multiple winding plates 203 arrayed around the fixed shaft 202 to form a containing cylinder. At the same time, multiple containing cylinders are arrayed outside the fixed shaft 202, and the silicon core tube is rolled up through the formed containing cylinder.

[0078] A protrusion 2031 is fixed at the center of one side of the surface of the winding plate 203, and a recess 2032 is opened at the center of the other side. The holding cylinder formed by the array of multiple winding plates 203 is closely arranged together to form a larger cylinder. Between two adjacent winding plates 203, the protrusion 2031 of the winding plate 203 extends into the recess 2032 of the adjacent winding plate 203. A slide plate 2033 and a hinge block 2034 are fixed to the inner surface of the winding plate 203. The two are on the same horizontal line and are respectively located on both sides of the winding plate 203.

[0079] Preferably, Figure 6Taking the first winding plate 203 on the middle right as an example, a pushing rod 2035 is hinged on the outer wall of the slide plate 2033, an auxiliary rod 2036 is hinged on the outer wall of the hinge block 2034, and a moving ring 2037 is hinged on the other end of the pushing rod 2035. The moving ring 2037 is sleeved on the outer wall of the fourth driving shaft 20210, and the other end of the auxiliary rod 2036 is hinged on the limiting ring 2038. The limiting ring 2038 is sleeved on the outer wall of the third driving shaft 2028 and fits onto the outer side of the third pushing ring 2029.

[0080] The upper end of the push rod 2035 is hinged to the outside of the slide plate 2033, and the other end is hinged to the outside of the movement ring 2037. The upper end of the auxiliary rod 2036 is hinged to the outside of the hinge block 2034, and the other end is hinged to the outside of the limit ring 2038. Figure 7 For example, the moving ring 2037 is sleeved on the outside of the fourth driving shaft 20210, and is tightly attached to the left outside of the fourth pushing ring 20211. The limiting ring 2038 is sleeved on the outside of the third driving shaft 2028. The limiting ring 2038 is located on the right side of the third pushing ring 2029, and the moving ring 2037 is driven by the fourth pushing ring 20211. With the movement of the fourth pushing ring 20211, the moving ring 2037 moves in the direction of the limiting ring 2038. At this time, the movement of the moving ring 2037 will drive the pushing rod 2035 to move, and move the winding plate 203 outward again for a distance.

[0081] The winding plate 203 array forms a holding cylinder, and the internal moving ring 2037 is driven by the pushing ring outside the driving shaft to move, and the limiting ring 2038 is an outer side of the driving shaft inside the moving ring 2037. The length of the holding cylinder is the same as the length difference between the front ends of the two driving shafts, and when the moving ring 2037 moves, the pushing rod 2035 and the auxiliary rod 2036 move inside the moving groove 2013 opened on the surface of the sleeve 2012.

[0082] Reference Fig.10 A sliding groove 2041 is provided on the inner wall of the limiting rod 204, a placement groove 2042 is also provided on the inner wall of the limiting rod 204, a guide groove 2043 is also provided on the end of the placement groove 2042, a push block 2044 is provided on the inner wall of the placement groove 2042, a sliding column 2045 is provided on the outer wall of the push block 2044, and the end of the sliding column 2045 extends to the inner wall of the placement groove 2042 and slidably cooperates therewith.

[0083] Among them, a plurality of arrays of limit rods 204 are installed on the outside of the fixed shaft 202, located on the outer wall of the sleeve 2012, and a sliding groove 2041 is opened on the inner surface of the limit rod 204. The protrusion 2031 on the outside of the winding plate 203 slides inside the sliding groove 2041. Similarly, the recess 2032 on the other side of the winding plate 203 slides with the protrusion 2015 on the surface of the fixed rod 2014.

[0084] The placement groove 2042 is above the slide groove 2041, and there is a guide groove 2043 at the top of the placement groove 2042. The push block 2044 slides inside the placement groove 2042. Initially, a portion of the push block 2044 is exposed outside the placement groove 2042. Through the sliding column 2045 on the surface of the push block 2044, the push block 2044 slides into the inside of the placement groove 2042 when squeezed.

[0085] Better, refer to Fig.10 , Fig.11 and Fig.12 An angular block 2046 is also provided inside the placement groove 2042, and a first end angle 2047 and a second end angle 2048 are provided on the outer wall of the angular block 2046. The first end angle 2047 is hinged to the inner wall of the placement groove 2042, and the outer wall of the second end angle 2048 is hinged with a hinged rod 2049, and the other end of the hinged rod 2049 is hinged with a blocking rod 20410. A guide column 20411 is provided on the outer wall of the blocking rod 20410, and the end of the guide column 20411 extends to the inner wall of the guide groove 2043 and slides with it, and a pulley 20412 is provided in an array on the inner wall of the guide column 20411.

[0086] Among them, the angle block 2046 is above the push block 2044, and the lower bottom end position of the angle block 2046 contacts the inclined surface of the push block 2044. Affected by the push of the push block 2044, the first end angle 2047 of the front end of the angle block 2046 is hinged inside the placement groove 2042, serving as a fulcrum for the hinged movement of the angle block 2046, and the second end angle 2048 of the angle block 2046 is located at the upper end of the angle block 2046, and the outside of the second end angle 2048 is hinged with a hinge rod 2049, and the other end of the hinge rod 2049 is hinged with a blocking rod 20410. The number of blocking rods 20410 is less than the number of limit rods 204, and the guide column 20411 on the outside of the blocking rod 20410 slides inside the guide groove 2043. When the push block 2044 is squeezed When pressed toward the inner side of the placement groove 2042, the inclined surface of the push block 2044 contacts the lower bottom end position of the angle block 2046, causing the angle block 2046 to flip over with the first end angle 2047 as the fulcrum, and the second end angle 2048 moves upward, pushing the hinge rod 2049 to move from an inclined state to a straight state, pushing the blocking rod 20410 upward. At this time, the guide column 20411 on the outer wall of the blocking rod 20410 is guided by the guide groove 2043 and tilted upward. When the guide column 20411 slides out of the guide groove 2043, the blocking rod 20410 detaches from the placement groove 2042 and flips down, and the top end position of the blocking rod 20410 falls into the opening 2016 on the surface of the fixing rod 2014, thereby fixing the blocking rod 20410.

[0087] In summary, when in use, the servo motor 104 drives the transmission gear 2011 to rotate through the wheel chain, and transmits it to the rotating shaft 201. The rotating shaft 201 rotates in the limit bearing 1021 above the fixed platform 102. The other part of the rotating shaft 201 extends to the outside of the shell 101 and is provided with a sleeve 2012. When the rotating shaft 201 rotates, the sleeve 2012 rotates together, and the fixed rod 2014 located inside the sleeve 2012 and the limit rod 204 on the outside rotate together. The winding plate 203 of the outer array of the sleeve 2012 rotates with the sleeve 2012 to wind up the silicon core tube. There are multiple winding plates 203 in the array, which form a containing cylinder. The multiple containing cylinders are combined into a longer cylinder for winding up the silicon core tube.

[0088] As the silicon core tube on the cylinder is rolled up, the thickness of the rolled silicon core tube increases, and the silicon core tube is rolled up between the limiting rod 204 and the fixing rod 2014, as shown in FIG. Fig.10 As shown, a placement groove 2042 is provided in the middle of the inner wall of each limiting rod 204, and the placement grooves 2042 have the same length. At the same time, a push block 2044 is arranged on the inner wall of each placement groove 2042, and the push block 2044 has the same height inside the placement groove 2042. When the thickness of the rolled silicon core tube increases, the silicon core tube hits the push block 2044 inside the placement groove 2042 of the inner wall of the limiting rod 204 located in the middle upwardly erected position, and the push block 2044 is squeezed by the silicon core tube and slides toward the inside of the placement groove 2042. With the movement of the push block 2044, the lower bottom end of the angular block 2046 in contact with the surface of the push block 2044 contacts the inclined surface of the push block 2044, and the angular block 2046 is turned over with the first end angle 2047 as the fulcrum. The second end corner 2048 of the angular block 2046 is pushed upward to push the upper baffle 20410 upward. When the baffle 20410 moves upward, the side guide column 20411 slides upward in the guide groove 2043. When the guide column 20411 slides out of the guide groove 2043, the baffle 20410 is separated from the placement groove 2042 and flipped down to fall on the opening 2016 on the surface of the fixed rod 2014. At this time, the baffle 20410 located inside the limit rod 204 erected upward in the middle, which is the first to be hit by the silicon core tube, falls down and presses on the rolled silicon core tube below, stops the servo motor 104, stops the rotation of the rotating shaft 201, and starts the first round of packaging of the silicon core tube on the sleeve 2012, using a loose buckle packaging method, such as Fig.14As shown, the packing tape is wrapped around the outermost silicon core tube of the outer circle of the silicon core tube roll once, and then wrapped around the outermost silicon core tube on the other side of the silicon core tube roll once more, and finally wrapped around the entire silicon core tube roll once to perform loose-loop packaging. The arrow in the figure points to the packaging direction, and then the servo motor 104 continues to rotate and stops. Each time it rotates to the upper baffle 20410 flipped down, a loose-loop packaging will be performed until all the baffles 20410 are flipped down. After the loose-loop packaging is completed, the servo motor 104 continues to rotate and continues to reel in the silicon core tube.

[0089] After the silicon core tube is rolled, it is packaged again in an 8-shaped packaging method. Fig.15As shown, the arrow in the figure points to the packaging path of the packaging tape. A packaging tape is packaged in layers, and the layer packaged by the buckle after the stop rod 20410 is flipped down is the inner layer, and then the newly rolled silicon core tube is the outer layer. An 8-shaped packaging method is adopted. The upper silicon core tube is packaged first, then passed over the top of the inner silicon core tube and then wrapped back, and the inner and outer silicon core tubes are packaged in layers. At this time, as the silicon core tube is rolled up, the limit rod 204 is separated from the fixed shaft 202 and then pulled out. At this time, the stop rod 20410 is located in the middle of the two layers of silicon core tubes, and the internal pulley 20412 is used. It is convenient to pull the blocking rod 20410 outward. When the blocking rod 20410 is pulled outward, a small gap will appear between the two layers of silicon core tubes. At this time, as the blocking rod 20410 is pulled out, when the blocking rod 20410 pulls out the first containing cylinder, the driving motor 105 rotates, driving the output shaft 20212 outside the fourth driving shaft 20210 to rotate. When the output shaft 20212 rotates, the fourth push column at the tail of the fourth driving shaft 20210 slides inside the driving groove 20213 outside the output shaft 20212, and slides forward inside the output shaft 20212. At this time, the fourth pushing ring 20211 at the front end of the fourth driving shaft 20210 pushes the moving ring 2037 under the winding plate 203 to move forward, so that the winding plate 203 is pushed outward for a distance. At this time, the protrusion 2031 of the adjacent winding plate 203 slides in the notch 2032 on the surface of the winding plate 203 pushed upward, and the packed silicon core tube is driven to move by the upward expansion of the winding plate 203. Because the 8-shaped packaging method is adopted, when the winding plate 203 is expanded, the silicon core tube moves adaptively in the packaging belt, tightening the packaging belt. When the blocking rod 20410 is pulled out of the second When placing a cylinder, the driving motor 105 drives the output shaft 20212 to continue to rotate, and the fourth driving shaft 20210 inside the output shaft 20212 drives the third driving shaft 2028 to slide forward, thereby driving the next winding plate 203 for placing a cylinder to be opened outward, and so on, the driving motor 105 drives the output shaft 20212 to rotate, thereby opening the winding plate 203 outward, tightening the silicon-core tube in the packing tape, and rolling and packing the silicon-core tube. Through the 8-shaped packing method, an extra layer of packing tape is added to the silicon-core tube to avoid slippage and breakage of the packing tape due to excessive tightening.
