Description

Technical Field

[0001] The invention relates to the field of hot melt adhesive compounding machines, in particular to a hot melt adhesive compounding machine for roller pressing and laminating. Background Art

[0002] Hot melt adhesive laminating machine refers to a processing machine that heats plastics, sheets, cloth, etc. to perform hot melt laminating processing, combines two or more different materials and applies a certain pressure to make them composite into one. Hot melt laminating machine is mostly used for the composite processing of clothing leather, waterproof coiled materials, soles and shoes, and light foam sheets. Its advantages are that the product has a long storage time, no signs of discoloration, is not easy to tear, has a strong laminating effect, and has a wide range of adaptability and stability; For example, a large roller hot melt adhesive laminating machine disclosed in publication number CN112109421B has a laminating device arranged on the side of the gluing device away from the second unwinder, and an automatic telescopic device capable of controlling the linear reciprocating motion of the upper part thereof is arranged on the laminating device, and the automatic telescopic device is connected to the bottom of the frame, and the upper part of the laminating device can be controlled to move linearly up and down by the automatic telescopic device, thereby controlling the pressure of squeezing the two layers of fabric when the laminating device is working, and can also be used to adjust the contact area between the laminating device and the fabric; Publication No. CN103302949A discloses a hot melt adhesive coating compound machine, which is connected to a position detector through a rotatable tension detection rod, an axial stretching roller, and a cylinder. The position detector is connected to a PLC, and the PLC is connected to an encoder behind a power motor of the axial stretching roller. The invention has the advantages of environmental protection, high adhesive adjustment accuracy, no deformation and wrinkling, high degree of automation, and high production efficiency. However, the above-mentioned hot-melt adhesive laminating machine still has the following problems during actual use: although the symmetrically arranged laminating mechanism is used to achieve the pressing and laminating of the materials, there is dust and dirt on the side of the materials that are bonded to each other before the two materials are laminated, making it difficult to effectively bond them during the subsequent hot-melt adhesive pressing and laminating, which easily reduces the bonding effect. At the same time, when the material is discharged through the discharge mechanism, the material is also prone to wrinkles, which leads to wrinkles and deviations in the subsequent material collection, affecting the quality of the composite fabric.

[0003] Publication No. CN118721954B discloses a roller-type laminating hot melt adhesive compound machine, comprising a compound machine body; the front ends of the compound pressure rollers on the upper and lower sides are fixedly provided with driving gears; and further comprising: a wrinkle removal mechanism is provided at the left end of the compound machine body; wherein an auxiliary material discharge roller is rotatably provided at the lower middle part of the compound machine body, and a first material guide roller is rotatably provided at the inner center position of the compound machine body; wherein a dust removal mechanism is provided at the upper middle part of the compound machine body.

[0004] The roller-type laminating machine for hot melt adhesive uses a wrinkle removal mechanism at the left end of the laminating machine body to assist in smoothing the material, while the dust removal mechanism removes dust from the inner wall of the material to be bonded, so that the gluing mechanism can achieve gluing and evenly spread the hot melt adhesive, so that the composite pressure roller can press and cover the materials to integrate and connect them, thereby ensuring the stability of the adhesion between the materials and preventing wrinkles and deviations after composite adhesion.

[0005] However, simple wheel scraping wrinkle removal is difficult to meet the wrinkle removal needs of the fabric, and although the dust removal step is close to the gluing, there is no protection between the two, so the fabric after the initial dust removal will still be stained with dust in the air before gluing, and when the glue roller is pressed and bonded, too much glue is used, and there will be a problem of glue leakage. If the excessive glue leakage is overcome, the amount of glue cannot meet the bonding needs and is difficult to control. Summary of the invention

[0006] In view of the shortcomings of the prior art, the present invention provides a hot melt adhesive laminating machine for roller pressing, which solves the problems raised in the above background technology.

The bottom end of each end plate is hinged with two rocker arms, and a roller is arranged between the two corresponding front and rear rocker arms, and the roller is rotatably connected with the front and rear rocker arms. A motor is fixedly installed on one of the rocker arms, and the output shaft of the motor acts on the main shaft of the roller; The end plate is provided with a plurality of through holes distributed up and down at the middle position corresponding to the two groups of auxiliary axes A. The through holes penetrate the end plate. A glue box is installed on the side of the end plate away from each other. The through holes are connected to the glue box. A pipe for glue discharge is installed at the outer end of the glue box.

[0008] Preferably, a push rod is hinged on one side of any rocker arm away from the rolling wheel, and rotatable slip rings are installed on the left and right sides of the upper part of the end plate. The upper end of the push rod passes through the slip ring and is slidably connected to the slip ring. A nut is installed on the upper end of the push rod, and a spring is fixedly installed on one side of the slip ring close to the end of the push rod, and the spring is rotatably connected to the nut.

[0009] Preferably, the processing component includes a glue coating tube and a dust collection box. The outer wall of the glue coating tube is provided with glue spray holes connected to the interior on both sides, the glue coating tube is located above the corresponding front and rear through holes, and the two ends of the glue coating tube are respectively fixed to the two end plates, and a pipeline for glue supply is installed at one end of the glue coating tube. The glue coating tube is located in the middle position of the two groups of auxiliary axes A. The dust collection box and the glue coating tube are located in a vertical straight line. The dust collection box is fixed on the angle steel frame, and a pipeline for exhausting air is provided at the upper end of the dust collection box. The interior of the dust collection box is a hollow structure, and the left and right sides of the dust collection box are provided with air holes connected to the interior, and there are multiple air holes on either side distributed at equal distances. The air holes are arranged obliquely downward and perpendicular to the axis connecting the centers of the arranged auxiliary axes A.

[0010] Preferably, the leveling assembly includes an air box, a top plate and a scraper strip. The air box is fixed above the angle steel frame. The interior of the air box is a hollow structure and its upper end is a flat structure. The top plate is suspended and fixed above the air box. The coil passes between the two and fits the upper surface of the air box. Two scraper strips are provided. The ends of the two scraper strips close to each other are elastically swingably connected to the top plate. The two scraper strips are V-shaped and staggered. Two hoses connected to the interior of the air box are installed on the air box. The other end of the hose is connected to the scraper strip after it passes over the top plate. A pipeline for supplying steam is provided at one end of the air box.

[0011] Preferably, the interior of the scraper strip is a hollow structure, a plurality of strip-shaped protrusions are provided at the bottom of the scraper strip, and microholes are provided at the tip positions of the strip-shaped protrusions for discharging steam.

[0012] Preferably, the material guiding assembly includes a cloth placing roller, an auxiliary shaft B and an auxiliary shaft C. The cloth placing roller is mounted on the angle steel frame and is farthest from the air box, followed by the auxiliary shaft B and the auxiliary shaft C. Both are mounted on the angle steel frame, and the auxiliary shaft B is higher than the auxiliary shaft C. After passing the cloth placing roller, the coil passes over the bottom of the auxiliary shaft B, and then passes over the top of the auxiliary shaft C until it fits the upper surface of the air box.

[0013] Preferably, the material guiding assembly further comprises an auxiliary shaft D, which is located at the other end of the air box. After the coil passes through the air box, it passes over the auxiliary shaft D and passes between the two sets of auxiliary shafts A.

[0014] Preferably, the winding assembly includes a winding roller and an auxiliary shaft E. The auxiliary shaft E and the winding roller are both installed in an angle steel frame. After the two groups of coils are closed by the roller pressing wheel, they are guided by the auxiliary shaft E and then wound by the winding roller.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The hot melt adhesive laminating machine for roller-pressing bonding has a polymerization component and a processing component. The two coils to be laminated will enter between the two sets of auxiliary shafts A in a V shape, and then the glue coating tube will spray hot melt adhesive between the two coils. The adhesive will be affected by gravity on the coils. As the distance between the two coils gets closer, the adhesive will close between the two coils, and the excess adhesive will keep going upward. The adhesive overflowing from the front and back of the coils will be sucked away by the negative pressure of the glue box for reuse. Therefore, when the two coils are closed under the action of the roller, the amount of adhesive between them can meet the demand, and the bonding effect is good. In addition, when the vacuum box is vacuuming under negative pressure, its action direction is at the position where the two coils are about to be glued, and an end plate is also provided. Therefore, after the dust is adsorbed away, it is difficult for additional dust to enter between the two coils, ensuring that there is no dust between the coils when gluing, and the bonding effect is better.

[0016] 2. The roll-type hot melt adhesive laminating machine is equipped with a flattening component. Due to the action of the scraper, the coil will be close to the air box. As high-temperature steam is filled into the air box, the temperature of the air box surface will increase, and the bottom of the coil passing through the air box surface will also be heated. The scraper on the surface can release steam. The steam acts on the coil along with the scraper, which can effectively remove the wrinkles on the coil. Compared with directly applying external force to keep it flat, this method is gentler, and the coil with smoothed wrinkles is not easy to deform again, and the dust content on the surface is reduced, which is convenient for later dust removal.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0022] like Figure 1-8As shown, a roller-type laminating hot melt adhesive compounding machine includes an angle steel frame 1, on which two raw material guide components 2, two leveling components 3, a polymerization component 4 and a processing component 5 are respectively installed. The two raw material guide components 2 are located on both sides of the upper end of the angle steel frame 1, the two leveling components 3 are arranged on the left and right and are located between the two raw material guide components 2, the polymerization component 4 is located between the two leveling components 3, and the processing component 5 is located above the polymerization component 4.

[0023] It also includes a winding component 6. The coils output by the two raw material guiding components 2 are guided to the winding component 6 for winding after passing through the flattening component 3, the processing component 5 and the polymerization component 4.

[0024] The aggregation component 4 includes two end plates 401, and two groups of auxiliary shafts A402 distributed on the left and right are arranged between the two end plates 401. Each group of auxiliary shafts A402 includes a plurality of equally distributed shafts. The two groups of auxiliary shafts A402 are distributed in a V-shape, and the bottom ends are gathered together. Two rocker arms 403 are hinged at the bottom end of each end plate 401, and a roller wheel 404 is arranged between the two corresponding front and rear rocker arms 403. The roller wheel 404 is rotatably connected relative to the front and rear rocker arms 403. A motor 405 is fixedly installed on one of the rocker arms 403, and the output shaft of the motor 405 acts on the main shaft of the roller wheel 404.

[0025] The end plate 401 is provided with a plurality of through holes 406 distributed up and down at the middle position where the two groups of auxiliary shafts A402 gather. The through holes 406 penetrate the end plate 401. A glue box 407 is installed on the side of the end plate 401 away from each other. The through holes 406 are connected to the glue box 407. The outer ends of the glue boxes 407 are installed with pipelines for glue discharge.

[0026] The angle steel frame 1 is a 120*60 square tube, with a roller surface width of 2300mm and an outer width of 2740mm. The equipment also includes a display screen and is controlled by a PLC program. All the rotatable devices included are controlled by a servo motor. The end plate 401 is a metal plate, which is fixed to the front and rear ends of the angle steel frame 1 by bolts. A hub motor is provided inside the auxiliary shaft A402, which can accurately rotate after being controlled by a servo drive board. The surface of the roller 404 is smooth, and the inside can be powered on to heat up. The motor 405 is used to control the rotation of the roller 404 and exert the rotational force on the two coils. The through hole 406 just corresponds to the position where the two coils are about to close. When there is too much adhesive between the two coils, it can be discharged from the position of the through hole 406. The pipeline outside the glue box 407 is connected to the negative pressure device, and a glue storage device is installed on the negative pressure device. The excess adhesive can be reused after being recycled, and the negative pressure force of the glue box 407 can also make the adhesive between the coils more evenly dispersed.

[0027] In order to adjust the pulling force, in an optimal implementation scheme: a push rod 408 is hinged on one side of any rocker arm 403 away from the roller wheel 404, rotatable slip rings 409 are installed on the left and right sides of the upper part of the end plate 401, the upper end of the push rod 408 passes through the slip ring 409 and is slidably connected to it, a nut 410 is installed on the upper end of the push rod 408, and a spring 411 is fixedly installed on one side of the slip ring 409 close to the end of the push rod 408, and the spring 411 is rotatably connected to the nut 410.

[0028] The end of the top rod 408 is provided with a thread, which cooperates with the nut 410. A bearing is provided at one end of the spring 411 away from the slip ring 409, and the bearing is connected to the nut 410, so when the nut 410 rotates, it can rotate relative to the spring 411, but the two cannot be separated. When the nut 410 is turned, the spring 411 can be stretched. At this time, the reaction force of the spring 411 can provide a greater pulling force to the pull rod, so that the roller 404 connected to the pull rod can exert a greater force on the coil. The nut 410 is mainly set to play the effect of fine-tuning the extrusion force. The daily spring 411 is sufficient to exert the pressure required for the extrusion compound. At the same time, the specifications of the spring 411 can be replaced. In response to different coils, the spring 411 with different elastic coefficients can be replaced.

[0029] The processing component 5 includes a glue coating tube 501 and a dust collection box 502. The left and right sides of the outer wall of the glue coating tube 501 are provided with glue spray holes 503 connected to the interior thereof. The glue coating tube 501 is located above the corresponding front and rear through holes 406. The two ends of the glue coating tube 501 are respectively fixed to the two end plates 401. One end of the glue coating tube 501 is installed with a pipeline for supplying glue. The glue coating tube 501 is located in the middle position of the two groups of auxiliary shafts A402. The dust collection box 502 and the glue coating tube 501 are located on a vertical straight line. The dust collection box 502 is fixed on the angle steel frame 1. The upper end of the dust collection box 502 is provided with a pipeline for exhausting air. The interior of the dust collection box 502 is a hollow structure. The left and right sides of the dust collection box 502 are provided with air holes connected to the interior thereof. The air holes on either side are multiple and equidistantly distributed. The air holes are arranged obliquely downward and perpendicular to the axis connecting the centers of the arranged auxiliary shafts A402.

[0030] The glue coating tube 501 is a device for preheating adhesive, and can also preheat PE film. In the prior art, some adhesives are in liquid form after preheating, so they can be adapted for use with the glue coating tube 501. By changing the pumping pressure, the hot melt adhesive can be discharged from the glue coating tube 501 and then sprayed onto the coil. After the adhesive is applied to the sides of the coils that are close to each other, they can be better bonded in the subsequent closed state. The same glue coating tube 501 can also be improved into a component for releasing PE film, which can release the PE film between two coils. The dust collection box 502 is connected to the existing negative pressure dust collection equipment, and a cavity is formed between the dust collection box 502 and the coil and the end plate 401. After the dust between the two coils is adsorbed, the dust in the air is not easy to enter between the two coils that are about to be closed, so the probability of secondary contamination is low.

[0031] The leveling component 3 includes an air box 301, a top plate 302 and a scraper 303. The air box 301 is fixed above the angle steel frame 1. The interior of the air box 301 is a hollow structure and its upper end is a flat structure. The top plate 302 is suspended and fixed above the air box 301. The coil passes between the two and fits the upper surface of the air box 301. Two scraper strips 303 are provided. The ends of the two scraper strips 303 close to each other are elastically swingingly connected to the top plate 302. The two scraper strips 303 are V-shaped and staggered. Two hoses 304 connected to the interior of the air box 301 are installed on the air box 301. The other end of the hose 304 is connected to the scraper strip 303 after crossing the top plate 302. One end of the air box 301 is provided with a pipeline for supplying steam.

[0032] High-pressure steam is introduced into the air box 301 before processing the coil. The high-temperature and high-pressure steam can quickly increase the temperature of the air box 301. The upper surface of the air box 301 is polished and the wall is thin, which can better transfer the heat of the steam. The hollow structure of the scraper 303 can circulate the steam inside the air box 301, and a torsion spring is installed at the connection between the scraper 303 and the top plate 302. When the coil moves forward, the scraper 303 will change its angle slightly if it encounters resistance. Under the reaction force of the torsion spring, it will quickly recover. Therefore, when the coil is actually released, the scraper 303 is not fixed in position.

[0033] The scraper strip 303 has a hollow structure inside. A plurality of strip-shaped protrusions are provided at the bottom of the scraper strip 303. Microholes are provided at the tip of each strip-shaped protrusion for discharging steam.

[0034] The bottom of the strip-shaped protrusions is provided with dense micro-holes by micro-drilling equipment. When high-pressure steam is introduced, the steam can be discharged from the micro-holes to heat the coil.

[0035] The material guiding assembly 2 comprises a cloth placing roller 201, an auxiliary shaft B202 and an auxiliary shaft C203. The cloth placing roller 201 is mounted on the angle steel frame 1 and is the farthest from the air box 301, followed by the auxiliary shaft B202 and the auxiliary shaft C203. Both are mounted on the angle steel frame 1. The auxiliary shaft B202 is higher than the auxiliary shaft C203. After the coil passes through the cloth placing roller 201, it passes over the bottom of the auxiliary shaft B202 and then over the auxiliary shaft C203 until it fits the upper surface of the air box 301.

[0036] The cloth placing roller 201 can place coils, fabrics, etc. The auxiliary shaft B202 and the auxiliary shaft C203 can be set as devices with hub motors for pulling the coils. If the coils are heavy, they can all be replaced with devices with power sources for stable and fast transmission of the coils.

[0037] The material guiding assembly 2 further includes an auxiliary shaft D204, which is located at the other end of the air box 301. After the coil passes through the air box 301, it passes over the auxiliary shaft D204 and passes between the two sets of auxiliary shafts A402.

[0038] The winding assembly 6 includes a winding roller 601 and an auxiliary shaft E602. The auxiliary shaft E602 and the winding roller 601 are both installed in the angle steel frame 1. After the two groups of coils are closed by the roller pressing wheel 404, they are guided by the auxiliary shaft E602 and then wound by the winding roller 601.

[0039] When in use, the two kinds of coils of raw materials are respectively on the two cloth placing rollers 201. As the equipment is pulled, the coils will pass through the auxiliary shafts B202 and C203 and enter the air box 301. Since the air box 301 is pre-heated by steam, when the coils pass through the air box 301, the bottom thereof will be heated up under the influence of the air box 301, and the scraper bar 303 above will always be in contact with the surface of the coils as the coils move forward. An elastic hinge is provided to enable the scraper bar 303 to move to a certain extent. When the steam is discharged from the air box 301 and acts on the scraper bar 303, the steam can be discharged from the contact position between the scraper bar 303 and the coils, so that a large amount of high-temperature steam acts on the coils to smooth out the wrinkles of the coils, and can also preheat the coils to facilitate subsequent gluing work. Moreover, the coils after being treated with steam spraying and the scraper bar 303 have less dust content. The auxiliary shaft D204 is reversed again, so that the two rolls will converge and be converged into a V shape by the two sets of auxiliary shafts A402. When they just converge, the dust box 502 is connected to the negative pressure device, so that the dust box 502 can absorb the excess dust between the two sets of rolls. Since the two sets of fabrics are located between the two end plates 401 to form a triangular structure, it is difficult for the excess dust to have a secondary impact on the rolls during vacuuming. After the vacuuming is completed, the surfaces of the two sets of rolls to be bonded have been completely clean. At this time, the hot melt adhesive or PE film is heated to allow the adhesive to enter between the two rolls. After the adhesive is processed on the surface of the rolls, as the rolls are closed and the roller 404 is affected, the two sets of rolls can be pressed and bonded, and the excess adhesive will be taken away in time by the negative pressure of the glue box 407. Then, with the reversing action of the auxiliary shaft E602, the two sets of rolls are basically completely bonded and finally wound up by the winding roller 601.
