Description

Technical Field

[0001] The invention relates to the field of roller core cloth wrapping, and more specifically to a roller core cloth wrapping mechanism for producing polyurethane rubber rollers. Background Art

[0002] In the production process of polyurethane rubber rollers, in order to improve the wear resistance of the rubber rollers and improve the performance of the rubber roller surface, the roller core of the rubber roller is usually wrapped with cloth. At present, in order to improve the production efficiency of roller core wrapping, the roller core wrapping mechanism is usually used to automatically wrap the roller core. In order to enhance the stability of the cloth on the roller core surface and the stability between multiple layers of cloth, the surface of the cloth is usually sprayed with glue by a glue spraying device;

[0003] However, most of the existing glue spraying equipment adopts a constant glue spraying pressure to spray glue on the fabric. However, due to the problem of different softness and hardness of fabrics in the production, storage, pretreatment and other links, when a constant glue spraying pressure is used to spray glue on fabrics of different softness and hardness, it is easy to reduce the effect of glue adhesion on the fabric surface. For example, when a larger glue spraying pressure is used to spray glue on soft fabrics, the larger impact force generated during the glue spraying process can easily make the glue penetrate into the soft fabric, reduce the glue on the surface of the soft fabric, and easily reduce the bonding effect between the fabrics and between the fabric and the roller core. Similarly, when a smaller glue spraying pressure is used to spray glue on the fabric, the glue liquid cannot be evenly spread on the fabric surface due to the hardness of the fabric, thereby reducing the glue spraying effect of the equipment on the hard fabric. Therefore, it is urgent to design a roller core wrapping mechanism for the production of polyurethane rubber rollers to solve the above problems. Summary of the invention

[0052] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0053] See also Figures 1 to 18 A roller core cloth wrapping mechanism for producing a polyurethane rubber roller includes a support frame 1, a reel 2, and a roller core 11. The reel 2 is wound with cloth 12, the support frame 1 is provided with a fixing component 5, a curing box 3 is fixedly installed on the support frame 1, a detection component 7 is provided in the curing box 3, a voltage regulating component 8 is provided in the curing box 3, and a speed regulating component 10 is provided on the curing box 3.

[0054] like Figure 1 - Figure 4 As shown, the fixing assembly 5 includes a sliding groove 51 provided on the support frame 1, and two sliding grooves 51 are provided, and a telescopic fixing frame 52 is slidably installed on each of the two sliding grooves 51, and a fixing cylinder 53 is penetrated and rotatably installed on each of the two telescopic fixing frames 52, and balls 55 evenly distributed in an annular shape are fixedly installed on each of the two fixing cylinders 53, and an annular sliding groove 54 is provided on each of the two telescopic fixing frames 52, and the balls 55 are slidably installed on the corresponding annular sliding groove 54;

[0055] A fixed plate is fixedly installed on the support frame 1, and a rotating cylinder 56 is penetrated and rotatably installed on the fixed plate. A transmission cylinder 57 is sealably penetrated and rotatably installed on the curing box 3. Elastic stoppers 58 are fixedly installed in the two fixed cylinders 53 and the rotating cylinder 56 and the transmission cylinder 57. Spring clamps 59 evenly distributed in an annular shape are fixedly installed in the two fixed cylinders 53 and the rotating cylinder 56 and the transmission cylinder 57.

[0056] from Figure 4 It can be seen that the multiple elastic blocks 58 are composed of a return spring and a conical cylinder, and the conical cylinders are fixedly connected to one end of the corresponding return spring, the fixed cylinder 53, the rotating cylinder 56 and the transmission cylinder 57 are each provided with a return spring, and the inner walls of the fixed cylinder 53, the rotating cylinder 56 and the transmission cylinder 57 are fixedly connected to the other end of the corresponding return spring, and in the initial state, the middle positions of the multiple conical cylinders squeeze the corresponding multiple spring clamps 59, so that the corresponding multiple spring clamps 59 are in a compressed state in the initial state.

[0057] After the glue spraying pressure in the liquid storage box 81 is adjusted, one end of the reel 2 can be inserted into the rotating cylinder 56. During this process, the right end of the reel 2 will continuously compress the elastic stopper 58 (such as Figure 459, the elastic stopper 58 is separated from the corresponding spring clamping plate 59, and the plurality of spring clamping plates 59 inside the rotating cylinder 56 clamp the right end of the reel 2, and then the telescopic fixing frame 52 on the left side is stretched upwards (as shown in FIG. Figure 2 In the direction shown, the two telescopic fixing frames 52 are in the initial state and are both in the retracted state) until the fixing tube 53 on the left telescopic fixing frame 52 is directly opposite to the other end of the reel 2, and then the left telescopic fixing frame 52 is manually pushed so that the left fixing tube 53 gradually approaches the other end of the reel 2 (as shown in FIG. Figure 2 The elastic stopper 58 in the left fixed cylinder 53 is compressed away from the corresponding spring clamping plate 59, and the plurality of spring clamping plates 59 in the left fixed cylinder 53 clamp and fix the left side of the reel 2 (as shown in the direction of FIG. 1 ). Figure 4 direction shown).

[0058] After the position of the reel 2 is fixed, the door of the curing box 3 is opened first, and then the right end of the roller core 11 is fixedly installed in the transmission cylinder 57 (such as Figure 4 The left end is fixedly mounted in the corresponding fixing cylinder 53.

[0059] After the reel 2 and the roller core 11 are fixedly mounted on the upper end of the support frame 1, one end of the cloth 12 wound on the reel 2 is passed through the tensioning roller 64, the guide roller, the curing box 3 and the partition inside the curing box 3 in sequence, and is fixedly mounted on the roller core 11 (combined with Figure 2 and Figure 3 It can be seen that in order to improve the winding effect of the cloth 12 on the reel 2 by the subsequent rotation of the roller core 11, a guide roller that can guide the movement of the cloth 12 is arranged on the support frame 1, and in order to facilitate improving the fixing effect between the cloth 12 that directly contacts the surface of the roller core 11 and the roller core 11, rubber can be coated on the surface of the roller core 11 before installing the roller core 11).

[0060] like Figure 1 - Figure 3 , Figure 5 As shown, a tensioning assembly 6 is provided on the support frame 1, and the tensioning assembly 6 includes a limit frame 61 fixedly installed on the support frame 1, and two limit frames 61 are provided. A threaded rod 62 is rotatably installed on the two limit frames 61, and a bevel gear 66 is fixedly installed on the two threaded rods 62. A sliding block 63 is threadedly installed on the two threaded rods 62, and a tensioning roller 64 is fixedly installed between the two sliding blocks 63. A rotating rod 65 passes through and rotatably installed on the support frame 1, and a bevel gear 2 is fixedly installed on the rotating rod 65. There are two bevel gears 2, and the two bevel gears 2 are meshed with the corresponding bevel gear 1 66.

[0061] When one end of the cloth 12 is fixed on the roller core 11, if the tension of the cloth 12 needs to be increased, the rotating rod 65 can be manually rotated clockwise (such as Figure 3 As shown in the direction, the two bevel gears 2 cooperate with the two bevel gears 1 66 to drive the two threaded rods 1 62 to rotate. At this time, the rotation of the two threaded rods 1 62 will drive the tension roller 64 to move downward (as shown in the direction of Figure 5 The cloth 12 is wound around the roller 11 and the tensioning force is adjusted to the desired direction. The tensioning force of the cloth 12 ... Figure 5 The effect of reducing the tension of the cloth 12 can be achieved.

[0062] like Figure 6 , Figure 7 As shown, the detection assembly 7 includes an electric telescopic rod 71 fixedly mounted on the top wall of the curing box 3, a pressure sensor 72 is fixedly mounted on the lower end of the electric telescopic rod 71, a pressing plate 73 is fixedly mounted on the lower end of the pressure sensor 72, a positioning plate 74 matched with the pressing plate 73 is fixedly mounted in the curing box 3, and a positioning rod (drawn but not marked in the figure, from Figure 7 As can be seen in the figure, there are two positioning rods.

[0063] After one end of the cloth 12 is fixed on the roller core 11, the lower end of the cloth 12 is in contact with the upper surface of the positioning plate 74, and the upper end of the cloth 12 is in contact with the lower surface of the pressing plate 73 (as shown in FIG. Figure 7 The purpose is to facilitate the subsequent detection component 7 to detect the softness and hardness of the cloth 12. At the same time, the positioning plate 74 can be used to limit the subsequent force movement of the cloth 12, thereby improving the flatness of the cloth 12 rolled up by the subsequent force rotation of the roller core 11.

[0064] After the tensioning force of the cloth 12 is adjusted, the electric telescopic rod 71 and the pressure sensor 72 can be started first. The operation of the electric telescopic rod 71 will drive the pressing plate 73 to move downward through the pressure sensor 72 to press the cloth 12. During this process, if the pressure value measured by the pressure sensor 72 rises rapidly, it is determined that the cloth 12 is a hard cloth 12, otherwise it is determined to be a soft cloth 12.

[0065] For example, the electric telescopic rod 71 is set to drive the pressing plate 73 to move down 2 mm at a speed of 1 mm per second (the thickness of the cloth 12 made of polyurethane material is usually between 0.5 mm and 3 mm). When the pressing plate 73 moves down to press the cloth 12 above the positioning plate 74, if the cloth 12 is soft, the cloth 12 is easily deformed after being pressed. At this time, the reaction force generated by the cloth 12 on the pressing plate 73 is small, and the pressure measured by the pressure sensor 72 will gradually increase from 0. On the contrary, when the cloth 12 is hard, the cloth 12 is not easily deformed under pressure, and the reaction force generated on the pressing plate 73 is large, and the pressure measured by the pressure sensor 72 will rise rapidly. Therefore, the hardness of the cloth 12 can be judged by the rising speed of the pressure value measured by the pressure sensor 72. In this way, the accuracy of the hardness detection of the cloth 12 can be effectively improved.

[0066] The fabric 12 may be soft or have different hardness during production and storage (if the fabric 12 is in a high temperature environment for a long time, some thermoplastic polyurethane fabrics 12 may soften, while in a low temperature environment, the fabric 12 may harden), as well as pretreatment.

[0067] The purpose of installing two positioning rods between the pressing plate 73 and the curing box 3 is to ensure that when the electric telescopic rod 71 drives the pressing plate 73 to move up and down (such as Figure 7 The pressing plate 73 can be moved in the vertical direction by two retractable positioning rods to ensure that the pressing plate 73 is always in contact with the upper surface of the cloth 12 when the pressing plate 73 presses the cloth 12 (as shown in the direction). Figure 7 The pressure sensor 72 is used to detect the softness and hardness of the fabric 12 through the pressing plate 73, which helps to improve the accuracy of the detection.

[0068] like Figure 2 , Figure 6 - Fig.13 As shown, the pressure regulating assembly 8 includes a liquid storage box 81 fixedly mounted on the curing box 3, the lower end of the liquid storage box 81 is fixedly connected with telescopic tubes 83 which are evenly distributed linearly, a pressure lifting plate 88 is fixedly mounted between the telescopic tubes 83, an adjusting tube 84 is fixedly connected between the telescopic tubes 83, a rotating shaft 810 is sealed and penetrated through the adjusting tube 84 and rotatably mounted, a pressure regulating component is installed between the pressure lifting plate 88 and the rotating shaft 810, a knocking component is installed on the rotating shaft 810, and a liquid spraying component is installed on the adjusting tube 84.

[0069] The pressure regulating component includes an air compressor 4 fixedly mounted on the curing box 3, an air injection pipe 82 is fixedly connected between the air compressor 4 and the liquid storage box 81, a servo motor 86 is fixedly mounted on the top wall of the curing box 3, a threaded rod 87 is fixedly mounted on the driving end of the servo motor 86, a nut is threadedly mounted on the threaded rod 87, and the nut is fixedly connected to the pressure lifting plate 88;

[0070] A first rack 89 is fixedly installed at the lower end of the lifting plate 88, a rotating gear 814 meshing with the first rack 89 is fixedly installed on the rotating shaft 810, a reciprocating screw 811 is fixedly installed on the rotating shaft 810, a ball nut is matched with the reciprocating screw 811, two ball nuts are provided, a sealing slider 813 is fixedly installed on one side of the two ball nuts, a limiting plate 812 is fixedly installed on the two sealing sliders 813, and the two limiting plates 812 are sealed and slidably installed in the adjusting tube 84.

[0071] The liquid spraying component includes a slide 819 provided in the regulating tube 84. There are two slides 819. A round rod 821 is rotatably mounted on each of the two slides 819. A glue spraying tube 85 is fixedly mounted between the two round rods 821. A sealing ring (not shown in the figure but not marked, from the figure) is fixedly mounted between the glue spraying tube 85 and the regulating tube 84. Fig.13 As can be seen in the figure, the two round rods 821 are fixedly mounted with a rotating gear 822, and the right limit plate 812 is fixedly mounted with a rack rod 820 (the right side here refers to Fig.12 , Fig.12 In the figure, the position of the slide groove 819 is the right side, and two rack rods 820 are provided, and the two rack rods 820 are matched with the corresponding rotating gear 2 822.

[0072] Before spraying glue on the cloth 12, start the air compressor 4 first. At this time, the operation of the air compressor 4 will inject gas into the liquid storage box 81 through the air injection pipe 82 (the liquid storage box 81 stores the glue required for the cloth 12 to be rolled up). When the pressure inside the liquid storage box 81 reaches the pressure required for subsequent glue spraying, the operation of the air compressor 4 can be stopped first.

[0073] During operation, the air compressor 4 will suck external gas into the air compressor 4, and after compressing this part of gas, the compressed gas will be input into the gas injection pipe 82 and the air supply pipe 102 respectively. Its specific working principle and internal components are all existing mature technologies and will not be further elaborated here.

[0074] If the pressure sensor 72 detects that the cloth 12 is soft, the pressure sensor 72 will start the servo motor 86. At this time, the operation of the servo motor 86 will drive the threaded rod 87 to rotate forward, so that the nut drives the lifting plate 88 to move downward (such as Fig. 9 In the direction shown in the figure, the multiple telescopic tubes 83 are stretched, and when the multiple telescopic tubes 83 are stretched downward, the glue spraying tube 85 is driven downward through the adjusting tube 84, so as to shorten the distance between the glue spraying tube 85 and the soft cloth 12.

[0075] At the same time, during the process of the lifting and pressing plate 88 being forced to move downward (such as Fig.10 The first rack 89 cooperates with the rotating gear 814 to enable the rotating shaft 810 to drive the reciprocating screw 811 to rotate. At this time, the rotation of the reciprocating screw 811 will cause the two limit plates 812 to move away from each other, thereby increasing the effective diameter of the glue input from the regulating tube 84 to the glue spraying tube 85 and reducing the glue spraying pressure from the glue spraying tube 85 to the cloth 12.

[0076] When the soft fabric 12 needs to be sprayed with glue, the air compressor 4 is started and the valves on the multiple telescopic tubes 83 are opened (not shown in the figure, the air compressor 4 is set to operate at a constant power during the process of the equipment covering the roll core 11 with the fabric 12, and the amount of gas input into the air injection pipe 82 and the air delivery pipe 102 is relatively uniform). At this time, the operation of the air compressor 4 will cause the glue inside the liquid storage box 81 to flow into the regulating pipe 84 under pressure, and finally be sprayed out from the glue spraying pipe 85. The spacing between the limit plates 812 is relatively large, and the operating power of the air compressor 4 is set to a constant value, that is, the glue spraying pressure of the liquid storage box 81 is constant. Therefore, according to the principle of the continuity equation in fluid mechanics, it can be concluded that when the glue spraying pressure of the liquid storage box 81 is constant, the volume flow rate of the rubber is also relatively fixed to a certain extent. At this time, when the regulating tube 84 increases the effective glue delivery pipe diameter to the glue spraying pipe 85, in order to keep the volume flow rate of the rubber unchanged, the speed of the rubber fluid will be reduced, thereby achieving the effect of reducing the glue spraying pressure of the glue spraying pipe 85 on the soft fabric 12.

[0077] During the process of winding the fabric 12, the roller core 11 can effectively improve the bonding effect between the fabrics 12 and improve the final overall cloth wrapping effect of the roller core 11 by spraying glue on the surface of the fabric 12. Since the roller core 11 is usually made of metal (such as steel, aluminum, etc.), when the fabric 12 (such as polyurethane fabric 12) is in direct contact with it, due to the difference in properties between the materials, the friction and affinity between the two are limited. Therefore, the glue can effectively fill the small gaps between the fabrics 12 and between the fabric 12 and the roller core 11, so that the multiple layers of fabric 12 are tightly wound around the roller core 11. In addition, after the roller core 11 is wrapped with cloth, when it is put into use and subjected to different degrees of pressure, friction and impact, the glue layer between the fabrics 12 and the fabric 12 cooperate to play an effective buffering role, which helps to reduce the occurrence of direct mechanical damage to the surface of the roller core 11.

[0078] During the glue spraying process of the equipment on the soft fabric 12, since the organizational structure of the soft fabric 12 is usually loose and the bonding force between the fibers is weak (such as soft polyurethane non-woven fabric), during the glue spraying process of the soft fabric 12, a higher glue spraying pressure can easily cause the glue to penetrate into the interior of the soft fabric 12, causing the glue layer on the surface of the soft fabric 12 to become thinner, thereby reducing the bonding effect between the soft fabric 12 and the roller core 11 and between the soft fabric 12, reducing the overall wrapping effect of the roller core 11 and the subsequent use effect. At the same time, if the glue spraying pressure of the glue spraying hose 85 on the soft fabric 12 is too high, it is easy to cause the soft fabric 12 to become dented or wrinkled, thereby destroying its flatness and further reducing the winding and coating effect of the soft fabric 12 on the roller core 11.

[0079] At the same time, when the glue spraying hose 85 sprays glue on the soft cloth 12 at a low pressure, shortening the distance between the glue spraying hose 85 and the soft cloth 12 can help the glue to be evenly sprayed on the surface of the soft cloth 12 under the action of its own gravity and a relatively low spraying pressure, thereby further improving the gluing effect of the equipment on the soft cloth 12. Since the glue spraying power of the glue spraying hose 85 is relatively small when the glue spraying hose 85 sprays glue at a low pressure, shortening the distance between the glue spraying hose 85 and the soft cloth 12 can help the glue to accurately fall on the surface of the soft cloth 12, thereby avoiding excessive diffusion of the glue before reaching the cloth 12 and failing to effectively coat the surface of the soft cloth 12.

[0080] At the same time, the two limit plates 812 move away from each other, and the right limit plate 812 drives the two rack rods 820 to move continuously to the right (such as Fig.12 In the direction shown in the figure), through the cooperation between the two rack rods 820 and the corresponding rotating gear 2 822, the glue spraying hose 85 can be driven to rotate clockwise by a certain angle with the two round rods 821 as the axis (the two round rods 821 are symmetrically arranged).

[0081] When the glue spraying hose 85 sprays glue on the soft fabric 12 at a low pressure, the glue sprayed by the inclined glue spraying hose 85 can generate a component force on the surface of the soft fabric 12 along the plane direction of the soft fabric 12. This component force can compact the fabric to a certain extent, enhance the tightness of the fit between the soft fabrics 12 during the subsequent winding process of the soft fabric 12, and further improve the cloth wrapping effect of the roller core 11. At the same time, if there are tiny wrinkles or undulations on the surface of the soft fabric 12, the inclined glue spraying hose 85 can make the glue better adapt to these irregular surfaces, and the glue sprayed at an inclined angle can flow along the undulations on the surface of the soft fabric 12, which helps to distribute the glue more evenly on the surface of the soft fabric 12.

[0082] If the cloth 12 detected by the pressure sensor 72 is a hard cloth 12, the pressure sensor 72 starts the operation of the servo motor 86, which drives the threaded rod 87 to rotate in the opposite direction, so that the lifting plate 88 moves upward (such as Fig. 9 As shown in the direction, during the upward movement of the lifting plate 88, the glue spraying tube 85 can be driven to move up a certain distance through the cooperation of the multiple telescopic tubes 83 and the adjusting tube 84, thereby increasing the distance between the glue spraying tube 85 and the hard cloth 12.

[0083] At the same time, during the process of the lifting plate 88 being forced to move upward (such as Fig.10 The first rack 89 cooperates with the rotating gear 814, the rotating shaft 810 and the reciprocating screw 811 to drive the two limit plates 812 closer to each other, thereby increasing the glue spraying pressure of the glue spraying hose 85 on the hard cloth 12.

[0084] Since the hard cloth 12 has high hardness and is not easy to deform, if low-pressure glue spraying is used, the glue liquid may not be evenly spread on the surface of the cloth 12 due to the hardness of the cloth 12. By increasing the glue spraying pressure of the glue spraying tube 85, the impact force of the glue liquid can be effectively increased, and the glue liquid can be quickly dispersed on the surface of the hard cloth 12, which can help improve the glue spraying effect of the equipment on the hard cloth 12. For some hard cloths 12 with tiny gaps, by increasing the glue spraying pressure of the glue spraying tube 85, the glue liquid can be more easily penetrated into the tiny gaps on the surface of the hard cloth 12, thereby improving the subsequent adhesion strength between the hard cloths 12, which helps to improve the cloth wrapping effect of the equipment on the roller core 11.

[0085] At the same time, when increasing the glue spraying pressure of the glue spraying hose 85 on the hard cloth 12, by increasing the distance between the glue spraying hose 85 and the hard cloth 12, it can be effectively avoided that the glue rebounds or forms uneven accumulation on the surface of the hard cloth 12 during the glue spraying process of the glue spraying hose 85 on the hard cloth 12. Because when the glue is sprayed at high pressure, if the distance between the glue spraying hose 85 and the hard cloth 12 is too short, the reaction force generated by the hard cloth 12 on the glue at this time can easily cause the glue to rebound, making it impossible for the glue to effectively adhere to the surface of the hard cloth 12. Therefore, by increasing the distance between the glue spraying hose 85 and the hard cloth 12, it can help the glue to have a certain space to disperse and slow down after being sprayed, so that the glue can hit the surface of the hard cloth 12 at a relatively appropriate speed and force, promote the glue to better penetrate into the texture of the surface of the hard cloth 12, and further increase the glue spraying effect of the equipment on the hard cloth 12.

[0086] At the same time, the lifting plate 88 moves upward, driving the two limit plates 812 to move closer to each other, and the right limit plate 812 drives the two rack rods 820 to gradually move to the left (such as Fig.12 The glue spraying tube 85 can be driven to rotate counterclockwise around the two round rods 821 until it is reset (as shown in the direction). Fig.12 In the direction shown), the glue spraying tube 85 can achieve the effect of vertically spraying glue on the hard cloth 12.

[0087] In the process of increasing the glue spraying pressure of the glue spraying hose 85 on the hard cloth 12, the vertical glue spraying method is adopted, which can cause the glue to act vertically on the surface of the hard cloth 12 with a greater impact force, further ensuring that the glue can fully fill the tiny pores and textures that may exist on the surface of the hard cloth 12, which helps to further improve the subsequent bonding strength between the hard cloths 12.

[0088] The sealing ring arranged between the glue spraying tube 85 and the adjusting tube 84 is made of elastic material, so as to ensure that the sealing ring can effectively seal the gap between the glue spraying tube 85 and the adjusting tube 84, and when the glue spraying tube 85 is rotated relative to the adjusting tube 84 under force, the glue spraying tube 85 can rotate by compressing or stretching the sealing ring.

[0089] like Figure 8 - Fig.11 As shown, the knocking component includes a driving roller 815 fixedly mounted on the rotating shaft 810, and two driving rollers 815 are provided. A plurality of limit members 816 are fixedly mounted on the adjusting tube 84, and a connecting rod 817 is slidably mounted between the corresponding two limit members 816, and one end of the connecting rod 817 is slidably mounted on the corresponding driving roller 815, and a knocking plate 818 is fixedly mounted on the connecting rod 817.

[0090] At the same time, the lifting plate 88 is forced to move up and down (such as Fig.10 When the drive shaft 810 rotates, the two drive rollers 815 on the shaft 810 rotate together with it. During the rotation of the two drive rollers 815, the thread grooves (from Fig.11 As can be seen in FIG. 1 , the driving force applied to the corresponding two connecting rods 817 can cause the corresponding connecting rods 817 to drive the corresponding knocking plates 818 to move up and down reciprocatingly (as shown in FIG. 1 ). Fig.11 The outer wall of the regulating tube 84 is intermittently knocked, and the vibration force generated in the process of knocking the regulating tube 84 will be transmitted to the glue spraying tube 85 through the two round rods 821, so that the automatic cleaning of the nozzle on the glue spraying tube 85 can be achieved by knocking and vibrating, which helps to improve the smoothness of the glue when the glue is sprayed out of the glue spraying tube 85 on the hard or soft cloth 12 during the glue spraying process, thereby improving the glue spraying effect of the glue spraying tube 85 on the cloth 12.

[0091] like Figure 1 - Figure 4 , Fig.14 - Fig.18 As shown, the speed regulating assembly 10 includes an air collecting box 101 fixedly mounted on the curing box 3 , a shaft 103 is sealably penetrated and rotatably mounted inside the air collecting box 101 , and a sealing mechanism is installed between the shaft 103 and the pressure lifting plate 88 .

[0092] The blocking mechanism includes a roller 109 rotatably mounted on the inner wall of the air collecting box 101, a spur gear 110 is fixedly mounted on the roller 109, a connecting plate 107 is fixedly mounted on the pressure plate 88, and a second rack 108 meshing with the spur gear 110 is fixedly mounted on the connecting plate 107;

[0093] A limiting groove 114 is provided in the air collecting box 101, and a blocking block 113 is slidably installed on the limiting groove 114. There are two blocking blocks 113, and the two blocking blocks 113 are both in contact with the inner top wall of the air collecting box 101. A rod body 112 is fixedly installed at the lower end of the two blocking blocks 113. A driving disk 111 is fixedly installed on the roller 109, and one end of the two rod bodies 112 is slidably installed on the driving disk 111. Fan blades 104 uniformly distributed in an annular shape are fixedly installed on the shaft 103. An air supply pipe 102 is fixedly connected between the air collecting box 101 and the air compressor 4. A ventilation hole matching the air supply pipe 102 is provided on the air collecting box 101 (drawn but not marked in the figure, from Fig.15 As can be seen in the figure), a cleaning component is installed on the air collecting box 101.

[0094] The cleaning component includes a positioning block fixedly installed on the curing box 3 , and there are two positioning blocks. An air jet pipe 106 penetrates and is fixedly installed between the two positioning blocks. A one-way exhaust pipe 105 is fixedly connected between the air jet pipe 106 and the air collecting box 101 .

[0095] A transmission assembly 9 is provided between the rotating cylinder 56 and the transmission cylinder 57. The transmission assembly 9 includes a parallel axis gear 1 92 fixedly mounted on the transmission cylinder 57, a parallel axis gear 2 93 meshing with the parallel axis gear 1 92 is fixedly mounted on the shaft 103, rotating wheels are fixedly mounted on the shaft 103 and the rotating cylinder 56, and a conveyor belt 91 is installed between the two rotating wheels.

[0096] When the air compressor 4 is running, air is injected into the liquid storage box 81 through the air injection pipe 82, prompting the glue spraying pipe 85 to spray glue on the cloth 12. Part of the gas generated by the air compressor 4 during operation will enter the air collecting box 101 along the air supply pipe 102 and the ventilation hole. In this process, the gas will drive the multiple fan blades 104 to drive the shaft 103 to rotate. During the rotation of the shaft 103, through the cooperation of the two rotating wheels and the conveyor belt 91, and the parallel shaft gear 1 92 and the parallel shaft gear 2 93, the rotating cylinder 56 and the transmission cylinder 57 can rotate with the shaft 103. However, since the tooth directions of the parallel shaft gear 1 92 and the parallel shaft gear 2 93 are opposite, the transmission cylinder 57 rotates in the opposite direction to the shaft 103 and the rotating cylinder 56. Therefore, when the rotating cylinder 56 rotates to drive the reel 2 to release the cloth 12 thereon, the transmission cylinder 57 will drive the roller core 11 to rotate to reel in the glue-coated cloth 12, thereby achieving the effect of continuous glue spraying of the equipment on the cloth 12.

[0097] If the detection component 7 detects that the cloth 12 is a soft cloth 12, the servo motor 86 drives the lifting plate 88 to move downward (such as Fig.15 The connecting plate 107 cooperates with the second rack 108 and the spur gear 110 to drive the roller 109 to drive the driving disk 111 to rotate. At this time, the driving disk 111 rotates through two arc grooves (from Fig.16 As can be seen in FIG. 1 , the driving force applied to the two rod bodies 112 can drive the two rod bodies 112 to drive the two blocking blocks 113 away from each other (combined with Fig.15 It can be seen that in the initial state, the two blocking blocks 113 cooperate to block the lower end of the ventilation hole), so as to gradually increase the effective diameter of the air supply pipe 102 to supply air to the air collecting box 101 through the ventilation port, and reduce the pressure of the air supply pipe 102 to drive the multiple fan blades 104 to rotate.

[0098] Since the operating power of the air compressor 4 is set to a constant value, when the diameter of the one-way exhaust pipe 105 on the air collecting box 101 does not change and the aperture of the ventilation hole for supplying air to the air collecting box 101 increases, in order to keep the flow rate unchanged, the air flow velocity at the ventilation hole is reduced. At this time, the impact force of the wind on the multiple fan blades 104 is relatively small, so the rotation speed of the multiple fan blades 104 in cooperation with the driving shaft 103 will also decrease accordingly.

[0099] When the rotation speed of the shaft 103 decreases, the cooperation between the rotating cylinder 56 and the driving cylinder 57 can reduce the release speed of the cloth 12 caused by the rotation of the reel 2 and the winding speed of the cloth 12 caused by the rotation of the roller core 11, thereby achieving the effect of reducing the moving speed of the soft cloth 12 during the low-pressure spraying of the glue spraying hose 85 on the soft cloth 12.

[0100] Since the organizational structure of the soft cloth 12 is usually loose, and the glue has a certain viscosity, after it contacts the soft cloth 12, the physical state of the surface of the soft cloth 12 is easily changed. If the moving speed of the soft cloth 12 is too fast at this time, the glue that has just contacted the soft cloth 12 may not be fully attached and diffused on the surface of the soft cloth 12, and it may be pulled by the fast-moving cloth 12, resulting in uneven distribution of the glue on the surface of the soft cloth 12, reducing the glue spraying effect of the equipment on the soft cloth 12. Therefore, in the process of low-pressure glue spraying on the soft cloth 12, by reducing the moving speed of the soft cloth 12, the glue coating effect of the equipment on the soft cloth 12 can be further ensured, that is, the effect of subsequent roller core 11 wrapping can be improved.

[0101] On the contrary, when the lifting plate 88 is forced to move upward, the glue spraying tube 85 is pressurized to spray glue on the hard cloth 12 (such as Fig.15In the direction shown, through the cooperation of the connecting plate 107, the second rack 108, the roller 109 and the driving disk 111, the two blocking blocks 113 can be driven closer to each other, gradually reducing the effective diameter of the ventilation holes to transport air to the inside of the air collecting box 101, so as to gradually increase the rotation speed of the plurality of fan blades 104 in cooperation with the driving shaft 103, the reel 2 and the roller core 11, that is, the moving speed of the hard cloth 12 in this process.

[0102] When the glue spraying hose 85 sprays glue on the hard cloth 12 with a large pressure, the moving speed of the hard cloth 12 is increased, which helps the glue to adhere to the surface of the hard cloth 12. Since the surface of the hard cloth 12 is relatively smooth, the glue will not be easily affected by the subsequent impact of the glue like the soft cloth 12 after the glue is quickly attached. Therefore, by increasing the moving speed of the hard cloth 12, the winding speed of the roller core 11 for the glue-coated hard cloth 12 can be effectively increased, thereby improving the cloth wrapping efficiency of the roller core 11.

[0103] At the same time, when the air supply pipe 102 continuously supplies air to the air collecting box 101, the driving shaft 103 rotates, and the excess air in the air collecting box 101 enters the air injection pipe 106 along the one-way exhaust pipe 105 and is ejected from the air injection pipe 106. Fig.15 It can be seen that the nozzles on the air jet pipe 106 are all tilted, so the impact force generated by the gas ejected from the air jet pipe 106 can blow the dust and other impurities adhering to the cloth 12 to one side, thereby effectively improving the cleanliness of the upper surface of the cloth 12, improving the accuracy of the subsequent detection component 7 for the hardness and softness of the cloth 12, and improving the adhesion effect of the glue on the surface of the cloth 12 when the subsequent glue spray hose 85 sprays glue on the cloth 12, thereby further helping to improve the cloth wrapping effect of the roller core 11.

[0104] At the same time, during the process of rolling the glued cloth 12, the heating device (not shown in the figure but not marked) arranged inside the curing box 3 is used. Figure 6 As can be seen in the figure, the glue-coated fabric 12 can be heated and cured, thereby enhancing the adhesive force of the glue on the fabric 12 and improving the overall performance of the fabric 12. At the same time, the partition (from the Figure 6 As can be seen in the figure), the heating device can perform centralized curing treatment on the fabric 12 on the roller core 11, thereby improving the heating efficiency of the heating device on the fabric 12.

[0105] Instructions for use: When the device is needed to wrap the roller core 11 with the cloth 12, first fix the reel 2 between the rotating cylinder 56 and the corresponding fixed cylinder 53 through the fixing assembly 5, and fix the roller core 11 between the transmission cylinder 57 and the corresponding fixed cylinder 53, and then pass one end of the cloth 12 through the tensioning roller 64, the guide roller and the curing box 3 in sequence to fix it on the roller core 11, and then adjust the tensioning force of the cloth 12 through the tensioning assembly 6.

[0106] After the tension of the cloth 12 is adjusted, the electric telescopic rod 71 and the pressure sensor 72 are started to detect the hardness of the cloth 12. If the cloth 12 is detected to be soft, the pressure sensor 72 starts the servo motor 86 to drive the pressure plate 88 to move the glue spraying tube 85 downward (such as Fig. 9 At the same time, through the cooperation of the pressure-lifting plate 88 and the pressure-adjusting component, the two limit plates 812 can be driven away from each other, thereby reducing the glue spraying pressure of the glue spraying tube 85 and achieving the effect of low-pressure glue spraying on the soft cloth 12.

[0107] At the same time, during the downward movement of the lifting plate 88 (such as Fig.15 In the direction shown, by cooperating with the blocking component to reduce the air supply pressure of the ventilation hole to the inside of the air collecting box 101, the rotation speed of the multiple fan blades 104 cooperating with the driving shaft 103 can be effectively reduced. At this time, the shaft 103 can effectively reduce the speed of the roller core 11 to roll up the cloth 12 by cooperating with the transmission component 9, thereby further ensuring the gluing effect of the equipment on the soft cloth 12.

[0108] If the detection component 7 detects that the cloth 12 is a hard cloth 12, the operation of the servo motor 86 will drive the lifting plate 88 to move upward (such as Fig. 9 In the process, the pressure-lifting plate 88 cooperates with the pressure-adjusting component and the blocking component to improve the gluing effect of the equipment on the hard cloth 12 by increasing the pressure and speed.

[0109] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
