Description

Technical Field

[0001] This invention relates to the field of yarn tube paper preparation technology, specifically to a manufacturing equipment and forming process for a compression-resistant and fold-resistant yarn tube paper. Background Technology

[0002] Yarn tube paper is an industrial technical paper used in chemical fiber equipment factories within the textile industry. It can be used to make the core of high-speed filament spinning bobbins. It not only requires high dry strength, wet strength, smoothness, and abrasion resistance, but also must be oil- and water-resistant. Furthermore, it must not fuzz, deform, or burst during polyester spinning after being rolled into a tube. Based on these characteristics, yarn tube paper is required to have a certain physical strength and a high basis weight.

[0003] Chinese Patent Publication No. CN114103384A discloses a high-ash-content yarn tube paper manufacturing equipment. An upper paperboard, a support paperboard, and a lower paperboard are fed into a first support plate and a second support plate via a feeding roller and tensioned on a tensioning roller. The upper and lower paperboards are then fed between a first pressure roller and a second pressure roller via a reversing roller. Adhesive is fed into a glue spraying frame through a glue inlet pipe and sprayed onto the upper and lower surfaces of the support paperboard through a nozzle. A drive mechanism drives the first and second pressure rollers to rotate. Simultaneously, the first and second pressure rollers press the upper paperboard, support paperboard, and lower paperboard together and bond them with adhesive, thus completing the processing of the yarn tube paper.

[0004] The aforementioned patent has the following defects:

[0005] 1. Yarn tube paper comes in various width specifications. The aforementioned patent has a fixed adhesive spraying width, which can only be applied to yarn tube paper of a single specification. Yarn tube paper with a larger width will result in uneven adhesive spraying, while a narrower width will result in adhesive being sprayed outside the yarn tube paper. For example, the high ash content yarn tube paper manufacturing equipment mentioned in patent publication number CN114103384A cannot adjust the yarn tube paper manufacturing equipment to spray adhesive on yarn tube paper of different specifications, which greatly reduces the scope of equipment application. It is necessary to replace the yarn tube paper manufacturing equipment of different specifications to produce yarn tube paper of different specifications.

[0006] 2. Existing yarn tube paper manufacturing equipment cannot collect excess glue sprayed on, resulting in glue waste and increased production costs. For example, a high ash content yarn tube paper manufacturing equipment with reference patent publication number CN114103384A lacks glue collection equipment, which makes it easy for glue to overflow when the yarn tube paper is squeezed by the pressure roller, resulting in glue waste. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a manufacturing equipment and forming process for compression-resistant and fold-resistant yarn tube paper. It solves the problems of fixed glue spraying width in yarn tube paper manufacturing equipment, which can only be applied to yarn tube paper of a single specification. Wide yarn tube paper will result in uneven glue spraying, while narrow yarn tube paper will result in glue being sprayed outside the yarn tube paper.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] This invention provides three technical solutions:

[0042] like Figure 1-8The first embodiment is shown: a manufacturing apparatus for pressure-resistant and fold-resistant yarn tube paper, including an operating table 1. Side plates 2 are fixedly installed on both the front and rear side walls of the operating table 1. Guide mechanisms for rolling the yarn tube paper are installed on the opposite side walls of the two side plates 2. A glue spraying mechanism 11 for spraying glue onto the yarn tube paper is installed at the top of the operating table 1 and to the right of the guide mechanisms. A glue storage tank 12 for supplying glue to the glue spraying mechanism 11 is installed at the bottom of the operating table 1. A first glue pump 13 is fixedly installed on the side wall of the glue storage tank 12. The output end of the first glue pump 13 is connected to the glue spraying mechanism 11 via a hose 14. A return pipe 15 for recovering excess glue from the glue spraying mechanism 11 is fixedly installed on the side wall of the glue storage tank 12. A second glue pump 16 is fixedly installed inside the return pipe 15. The system includes a glue spraying box 111, a glue spreading plate 112 fixedly mounted on the inner wall of the glue spraying box 111, and long rectangular paper inlets on the left and right sides of the outer wall of the glue spraying box 111. A flexible hose 14 is connected to the glue spreading plate 112 for conveying glue. The paper inlets are located on the left and right sides of the glue spraying box 111, and there are two glue spraying mechanisms 11 on each side of the left and right sides, arranged vertically. The top and bottom of the glue spreading plate 112 are provided with multiple threaded through holes in a rectangular array. The threaded through holes are threadedly connected to nozzle assemblies 113 for spraying glue. The front and rear sides of the outer wall of the glue spreading plate 112 are respectively slidably fitted with a first glue spraying range adjustment assembly 114 and a second glue spraying range adjustment assembly 115. A second motor is fixedly mounted on the top of the glue spraying box 111 by a bracket. 116. A gear 117 is fixedly installed at the output end of the second motor 116 to change the position of the first glue spraying range adjustment component 114 and the second glue spraying range adjustment component 115. A recycling component 118 for collecting glue is fixedly installed on the right side wall of the glue spraying box 111. The guiding mechanism includes a first guide roller 3, a second guide roller 4, a third guide roller 5, a fourth guide roller 6, a pulley 7, a transmission belt 8, a gear 9, and a first motor 10. The first guide roller 3, the second guide roller 4, the third guide roller 5, and the fourth guide roller 6 are vertically distributed from top to bottom. The pulley 7 is fixedly installed at one end of the first guide roller 3 and the third guide roller 5, respectively. The transmission belt 8 is sleeved on the outer wall of the first guide roller 3 and the third guide roller 5 for transmitting power. The four gears 9 are... The first guide roller 3, the second guide roller 4, the third guide roller 5, and the fourth guide roller 6 are fixedly installed at the ends away from the pulley 7. Adjacent gears 9 are meshed with each other. The first guide roller 3, the second guide roller 4, the third guide roller 5, and the fourth guide roller 6 are all rotatably mounted on the opposite side walls of the two side plates 2 via rotating shafts. The first motor 10 is fixedly mounted on the outer wall of the side plate 2, and its output shaft rotates through the side plate 2 and is fixedly connected to the first guide roller 3. Gap is provided between the first guide roller 3 and the second guide roller 4, and between the third guide roller 5 and the fourth guide roller 6, for the passage of the yarn tube paper. The gap distance is adapted to the thickness of the yarn tube paper. The first glue spraying range adjustment component 114 and the second glue spraying range adjustment component 115 are two components with identical structures.T-shaped sliders are fixedly installed on both sides of the inner wall of the first glue spraying range adjustment component 114. T-shaped grooves matching the T-shaped sliders are opened on the front and rear sides of the left and right side walls of the glue spreading plate 112. The T-shaped sliders are slidably connected in the T-shaped grooves. The width of the yarn tube is less than the maximum width of the glue spreading plate 112. The first motor 10 rotates at a uniform speed, not exceeding 20 r / min. The second glue spraying range adjustment component 115 includes a drive sleeve 1151 and a rack 1152. The rack 1152 is fixedly installed on the top of the drive sleeve 1151. The rack 1152 and the gear 117 are meshed together, and the rack 1152 has chamfers on both the upper and lower sides of the inner wall near the second motor 116.

[0043] like Figure 9 The second embodiment is shown, and its main difference from the first embodiment is that: a manufacturing device for pressure-resistant and fold-resistant yarn tube paper, the nozzle assembly 113 includes a glue dispensing tube 1131 and a baffle 1132 fixedly disposed on the inner wall of the glue dispensing tube 1131. The baffle 1132 has a glue dispensing through hole 1133 for glue to pass through. A glue supply tube 1135 is slidably connected inside the glue dispensing tube 1131 and located on one side of the baffle 1132. A sealing plunger 1134 for sealing the glue dispensing through hole 1133 is fixedly disposed on the side wall of the glue supply tube 1135 near the baffle 1132. A glue dispensing head 1136 is fixedly disposed at the end of the glue supply tube 1135 away from the baffle 1132. A spring 1137 is sleeved on the outer wall of the glue supply tube 1135 and located between the glue dispensing tube 1131 and the glue dispensing head 1136. Glue dispensing holes communicating with the glue supply tube 1135 are evenly disposed on the outer wall of the glue dispensing head 1136. The number of dispensing holes 1133 is the same as that of the sealing plungers 1134, and their positions correspond one-to-one. After the dispensing head 1136 is squeezed, the sealing plungers 1134 enter the dispensing holes 1133 to block the dispensing holes 1133 and prevent the glue from flowing out.

[0044] like Figure 10The third embodiment is shown, the main difference from the second embodiment being: a manufacturing device for pressure-resistant and fold-resistant yarn tube paper, wherein the recycling component 118 includes a recycling box 1181, a filter plate 1182 for filtering glue impurities is fixedly installed inside the recycling box 1181, and side plates 1183 are fixedly installed on both sides of the top of the recycling box 1181. A first extrusion roller 1184 and a second extrusion roller 1185 are respectively rotatably installed on the opposite side walls of the two side plates 1183 and are vertically distributed vertically. The first extrusion roller 1184, the second extrusion roller 1185, and a first paper guide are also included. Roller 3, second guide roller 4, third guide roller 5, and fourth guide roller 6 are all composed of a metal drive shaft and a rubber protective sleeve. The rubber protective sleeve is fixedly fitted on the outer wall of the metal drive shaft. The rubber protective sleeve not only prevents damage to the yarn tube paper, but also has a certain elasticity, allowing yarn tube paper with a thickness greater than the distance between the first guide roller 3 and the second guide roller 4 or between the first squeeze roller 1184 and the second squeeze roller 1185 to pass through, thus improving its applicability. The distance between the third guide roller 5 and the fourth guide roller 6 is the same as the distance between the first guide roller 3 and the second guide roller 4.

[0045] This invention also provides a forming process for compression-resistant and fold-resistant yarn tube paper, the specific method including the following steps:

[0046] Step 1, Pre-treatment before glue spraying: Place one end of each of the two yarn tubes into the gap between the first guide roller 3, the second guide roller 4, the third guide roller 5, and the fourth guide roller 6, respectively, and manually pass the two yarn tubes through the two vertically distributed rectangular paper inlets on the glue spraying box 111; one yarn tube passes through the top of the glue cloth plate 112, and the other yarn tube passes through the bottom of the glue cloth plate 112, and pull the two yarn tubes out from the other side of the glue spraying box 111 and wrap them around the yarn tube winding roller.

[0047] Step 2, Spraying Adhesive: The first motor 10 drives the first guide roller 3, the second guide roller 4, the third guide roller 5, and the fourth guide roller 6 to rotate. Since one end of each of the first guide roller 3, the second guide roller 4, the third guide roller 5, and the fourth guide roller 6 is equipped with a gear 9, and adjacent gears 9 mesh with each other, and the pulleys 7 at one end of the first guide roller 3 and the third guide roller 5 transmit power through the transmission belt 8, the first guide roller 3, the second guide roller 4, the third guide roller 5, and the fourth guide roller 6 can push the yarn tube paper to the right by friction while rotating. The first glue pump 13 draws out the glue from the glue storage tank 12 and sprays it onto the opposite side walls of the two yarn tube papers through multiple nozzle assemblies 113 at the top and bottom of the glue application plate 112.

[0048] Step 3, Glue Spraying Range Adjustment: The second motor 116 drives the gear 117 to rotate. The drive gear 117 meshes with the rack 1152 in the first glue spraying range adjustment assembly 114 and the second glue spraying range adjustment assembly 115. Therefore, when the gear 117 rotates counterclockwise or clockwise, it can move the first glue spraying range adjustment assembly 114 and the second glue spraying range adjustment assembly 115 closer or further apart, changing the distance between the first glue spraying range adjustment assembly 114 and the second glue spraying range adjustment assembly 115. The nozzle assembly 113 between the second glue spraying range adjustment component 115 and the 14th nozzle assembly 113 can spray glue normally. One end of the drive sleeve 1151 is chamfered to facilitate the extrusion head 1136, so that the glue delivery tube 1135 pushes the sealing plunger 1134 into the glue outlet hole 1133 to prevent glue from flowing out. Conversely, the spring pushes the glue outlet head 1136 to move away from the glue delivery tube 1131, so that the glue outlet hole 1133 can spray glue normally. In the above way, the number of nozzle assemblies 113 in the normal glue spraying state can be controlled.

[0049] Step 4: Glue recycling: After the glue is sprayed, the two yarn tubes pass through the recycling assembly 118. The first extrusion roller 1184 and the second extrusion roller 1185 together squeeze the yarn tubes passing between them. The squeezed-out glue falls into the recycling bin 1181 under the action of gravity. After being filtered by the filter plate 1182, it is stored in the recycling bin 1181. The second glue pump 16 pumps the glue in the recycling bin 1181 back into the glue storage tank 12 through the glue return pipe 15, so that the excess glue is squeezed out and recycled for reuse.
