Technical Field

[0002] Polypropylene mat is a mat made of polypropylene material. It has the advantages of light weight, low moisture absorption rate and small electrostatic effect. Therefore, it is often used as industrial cloth. The lamination process can make the polypropylene mat material composite, thereby improving the performance of the polypropylene mat.

[0003] The existing polypropylene pad fabric laminating device manually places flexible pads, laminated steel plates, polypropylene pad fabrics soaked in adhesive, laminated steel plates and flexible pads layer by layer on a horizontal laminating tray, and puts the laminating tray into the device for lamination. In actual use, the staff needs to use tools to align the laminated steel plates and the polypropylene pad fabrics. The alignment steps are cumbersome, and when the staff aligns the laminated steel plates on the top layer, in order to improve the alignment effect, they often press the top surface of the laminated steel plates with their thumbs, thereby leaving sweat fingerprints or grease fingerprints, causing corrosion of the laminated steel plates, thereby reducing the flatness of the laminated steel plates and the effect of spreading pressure, resulting in a reduction in the life of the laminated steel plates. When the lamination process over-extrudes the polypropylene pad fabric, or the polypropylene pad fabric absorbs too much adhesive, the laminated adhesive will overflow from between the two laminated steel plates to form a colloid, resulting in low quality of the laminated polypropylene pad fabric.

[0029] like Figure 1-Figure 2 , Fig.10 and Fig.12As shown, it also includes an exhaust unit 7, which includes an exhaust shell 701. The exhaust shell 701 is fixedly connected to the top of the upper laminated shell 602, and variable pitch studs 702 are symmetrically rotatably connected in the exhaust shell 701.

[0030] like Figure 10-12 As shown, the pressure limiting unit 8 includes a limiting housing 801, the top of the exhaust housing 701 is fixedly connected to the limiting housing 801, a fourth vent hole 6025 is opened in the upper laminated housing 602, a T-type air intake valve 8011 is installed on the top of the upper laminated housing 602, the T-type air intake valve 8011 is connected to the fourth vent hole 6025, one end of the limiting housing 801 is connected to the T-type air intake valve 8011 through a hose, and the T-type air intake valve 8011 is connected at two ends or three ends, and a rotating column 802 is rotatably connected in the limiting housing 801, and the limiting A second motor 804 is installed on the top of the limiting shell 801, and the output shaft of the second motor 804 is fixedly connected to the rotating column 802.

A piston column 805 is slidably connected inside the limiting shell 801, and a second compression spring is connected between the limiting shell 801 and the piston column 805. The bottom of the piston column 805 contacts and squeezes the pressure cylinder 803.

[0031] In the initial state, the roller 504 at the front end contacts the lower laminating frame 2 under the action of the torsion spring, and the rear side of the driving frame 202 contacts the lower laminating frame 2. The staff first pulls the handrail 301, so that the handrail 301 drives the sliding support frame 501 to slide in the second sliding groove 201 through the lower laminating bracket 3. During the sliding of the sliding support frame 501, the sliding support frame 501 slides out of the second sliding groove 201 and slides on the sliding guide frame 502 until the front end of the sliding support frame 501 is in contact with the sliding guide frame 502. The hooked end of the guide frame 502 contacts, and the lower laminating bracket 3 is in an inclined state at this time. The movement of the lower laminating bracket 3 causes the first flexible plate 302 to move synchronously, so the first flexible plate 302 keeps tilting synchronously. During the sliding out of the lower laminating bracket 3, the elastic member 203 is released to push the driving frame 202 to move forward. The driving frame 202 moves and drives the gear 205 to rotate through the rack 204. The gear 205 rotates to make the knife 206 disengage from the driving frame 202, so that the knife 206 can cut off the excess polypropylene pad fabric by resetting.

[0032] After tilting the first flexible board 302, the staff places the bottom laminated steel plate, the polypropylene pad fabric and the top laminated steel plate neatly in sequence on the first flexible board 302, wherein the front end of the bottom laminated steel plate and the front end of the top laminated steel plate are in contact with the lower laminate bracket 3, so that the front end of the bottom laminated steel plate and the front end of the top laminated steel plate are easier to align. Then the staff pushes the handrail 301, so that the handrail 301 drives the sliding support frame 501 to slide on the sliding guide frame 502 through the lower laminate bracket 3. The sliding support frame 501 will detach from the sliding guide frame 502 during the sliding process and slide back into the second sliding groove 201, and complete the reset, so that the second sliding groove 201 drives the lower laminate bracket 3 to squeeze the driving frame 202 to reset, and the driving frame 202 moves When the sliding support frame 501 slides on the sliding guide frame 502, the excess polypropylene pad fabric will fall on the driving frame 202, and the driving frame 202 moves through the rack 204 to drive the gear 205 to rotate. The gear 205 rotates to make the gate knife 206 fit the driving frame 202 again and reset, thereby cutting off the excess polypropylene pad fabric. The excess polypropylene pad fabric will slide out of the lower laminating frame 2 along the inclined surface at the top of the driving frame 202, so as to remove the excess polypropylene pad fabric and prevent the excess polypropylene pad fabric from interfering with the subsequent lamination process of the polypropylene pad fabric. When the support frame 501 slides into the second sliding groove 201 and resets, the top laminated steel plate will contact and squeeze the cleaning roller 405, causing the cleaning roller 405 to slide upward along the first sliding groove 4041. The cleaning roller 405 slides upward to squeeze the scraper 412 to move, thereby compressing the first compression spring. The cleaning roller 405 slides upward along the first sliding groove 4041 and rotates at the same time, so that the dust on the top laminated steel plate is adhered by the cleaning roller 405, preventing the dust from being distributed on the top laminated steel plate and causing uneven heating of the top laminated steel plate during lamination. If the staff leaves sweat fingerprints or grease fingerprints on the top laminated steel plate when placing the top laminated steel plate, in order to better align the front end of the top laminated steel plate with the lower laminating bracket 3, the staff may leave sweat fingerprints or grease fingerprints on the top laminated steel plate. , fingerprints will corrode the top laminated steel plate, thereby reducing the service life of the top laminated steel plate. The cleaning roller 405 will clean the fingerprints left on the top laminated steel plate during the rotation process. The fingerprints and dust are cleaned by the cleaning roller 405, so that the top laminated steel plate is kept clean, thereby avoiding the problem of corrosion of the top laminated steel plate and increasing the service life of the top laminated steel plate. The rotation of the cleaning roller 405 will move the wiped dust, sweat and grease to the scraper 412. The scraper 412 will scrape the sweat and grease on the surface of the cleaning roller 405 and leave them on the scraper 412. At the same time, due to the static electricity on the scraper 412, the dust on the surface of the cleaning roller 405 will be adsorbed by the scraper 412 when it is close to the scraper 412, thereby completing the cleaning of the cleaning roller 405.Prevent dust on the cleaning roller 405 from interfering with the lamination of the polypropylene pad fabric and preventing sweat and grease from corroding the laminated steel plate.

[0033] During the resetting process of the sliding support frame 501, the bottom laminated steel plate and the top laminated steel plate will contact and squeeze the roller 504 at the rear end, and the roller 504 at the rear end will move, thereby driving the L-shaped frame 503 to rotate, and causing the torsion spring to store elastic potential energy. The rotation of the L-shaped frame 503 causes the roller 504 at the front end to rotate and detach from the lower lamination frame 2, and squeeze the left or right side of the bottom laminated steel plate and the top laminated steel plate, so that the bottom laminated steel plate and the top laminated steel plate drive the polypropylene pad fabric to be located in the middle of the lower lamination bracket 3, preventing the polypropylene pad fabric from being unevenly heated due to its position close to the edge of the lower lamination frame 2 when being laminated and heated. When the bottom laminated steel plate and the top laminated steel plate are adjusted to their positions, the bottom laminated steel plate and the top laminated steel plate pass between the two rollers 504 at the rear end, and at this time, the roller 504 at the front end is located directly in front of the roller 504 at the rear end.

[0034] After the sliding support frame 501 is reset, the staff begins to laminate the polypropylene pad fabric. The staff starts the first motor 604. The output shaft of the first motor 604 rotates to drive the screw 603 to rotate. The rotation of the screw 603 causes the lower lamination frame 2 to move upward along the rear end vertical pole 601, thereby driving the lower lamination bracket 3 to move upward through the sliding support frame 501. The lower lamination bracket 3 drives the bottom laminated steel plate, the polypropylene pad fabric and the top laminated steel plate to move upward through the first flexible plate 302. In the process of the lower lamination frame 2 moving upward, the lower lamination frame 2 will drive the second positioning frame 407 to move upward. The movement of the second positioning frame 407 causes the friction ring 406 to rotate through friction. The rotation of the friction ring 406 drives the installation shell 404 to rotate synchronously through the rotating frame 403, thereby causing the installation shell 404 to detach from the lower lamination frame 2. The installation shell 404 rotates The cleaning roller 405 is driven to move synchronously, and the installation shell 404 rotates through the third positioning frame 411 to drive the scraper 412 to move synchronously. Since the rotation radius of the installation shell 404 is greater than the outer diameter of the friction ring 406, the movement speed of the installation shell 404 is faster than the lower lamination frame 2, thereby avoiding the collision of the lower lamination frame 2 with the rotating frame 403. The friction ring 406 keeps rotating until it disengages from the second positioning frame 407, so that the cleaning roller 405 avoids the bottom laminated steel plate, the polypropylene pad fabric and the top laminated steel plate. At the same time, the installation shell 404 rotates to disengage the round head column 408 from the lower lamination frame 2, so that the first tension spring contracts and pulls the wedge block 409. The movement of the wedge block 409 causes the round head column 408 to move synchronously, and causes the cutting knife 410 to slide into the installation shell 404, to prevent the cutting knife 410 from cutting the staff and posing a safety threat to the staff.

[0035] When the lower lamination frame 2 moves upward to contact with the upper lamination shell 602, the second flexible plate 6023 will contact and squeeze the top laminated steel plate, so that the top laminated steel plate will exert a sufficiently large pressure on the polypropylene pad fabric. At this time, the lower lamination frame 2, the lower lamination bracket 3 and the upper lamination shell 602 form a first cavity. Then the staff starts the heating plate 6021, and the heating plate 6021 generates heat, which is evenly diffused through the heat spreader 6022. The heat of the heat spreader 6022 is transferred to the top laminated steel plate through the second flexible plate 6023, and finally transferred to the polypropylene pad fabric through the top laminated steel plate, so that the adhesive on the polypropylene pad fabric fully bonds the polypropylene pad fabric. In order to improve the bonding effect of the polypropylene pad fabric, the work The personnel starts the second motor 804, and the output shaft of the second motor 804 rotates through the rotating column 802 to drive the pressing cylinder 803 to rotate. The rotation of the pressing cylinder 803 causes the two meshed variable pitch studs 702 to rotate through extrusion and friction. It is worth noting that since the lower lamination frame 2, the lower lamination bracket 3 and the upper lamination shell 602 form a first cavity, the first cavity is connected to the first vent hole 6024 in the upper lamination shell 602, and the gas in the first cavity enters the second vent hole 7011 through the first vent hole 6024, and enters the thread of the variable pitch stud 702. Since the two variable pitch studs 702 are tightly meshed, the gas in the thread of the variable pitch stud 702 is blocked from flowing, and as the variable pitch stud 702 As the variable pitch stud 702 rotates, the pitch of the thread of the variable pitch stud 702 gradually decreases, and the space where the gas in the thread of the variable pitch stud 702 is located gradually decreases, so that the gas is compressed and finally released to the outside through the third vent hole 7012, thereby causing the air pressure in the first cavity composed of the lower lamination frame 2, the lower lamination bracket 3 and the upper lamination shell 602 to gradually decrease, making the adhesive easier to melt, and reducing the content of the adhesive dissolved in the air, thereby improving the bonding effect of the adhesive, thereby improving the lamination effect of the polypropylene pad fabric. It is worth noting that the limiting shell 801 and the piston rod 805 form a second cavity, and the first cavity is connected to the second cavity through a hose, a T-type air inlet valve 8011 and a fourth vent hole 6025. Therefore, as the first cavity As the air pressure decreases, the air pressure in the second cavity also decreases, causing the second cavity to pull the piston column 805 to move upward along the limiting shell 801. At the same time, the second compression spring is compressed, and the piston column 805 moves, causing the pressure cylinder 803 to be pulled by the second tension spring and move upward. The pressure cylinder 803 is separated from the variable pitch stud 702, so that the variable pitch stud 702 no longer rotates. At this time, the air pressure in the first cavity composed of the lower lamination frame 2, the lower lamination bracket 3 and the upper lamination shell 602 no longer changes, preventing the air pressure in the first cavity from being too low, causing bubbles to continue to emerge from the adhesive, thereby reducing the bonding effect of the adhesive. At this time, the output shaft of the second motor 804 causes the pressure cylinder 803 to idle through the rotating column 802, and then the second motor 804 is turned off.

[0036] The polypropylene pad fabric is laminated under the action of heating, low air pressure and high pressure. Then the staff adjusts the T-type air inlet valve 8011 to allow the outside air to enter the first cavity composed of the lower lamination frame 2, the lower lamination bracket 3 and the upper lamination shell 602 through the T-type air inlet valve 8011 and the fourth air vent 6025, so that the air pressure in the first cavity gradually increases. At the same time, the outside air enters the limiting shell 801 through the T-type air inlet valve 8011 and the hose, so that the air pressure in the limiting shell 801 increases, so that the second compression spring is reset to squeeze the piston column 805, and the piston column 805 moves to push the pressure cylinder 803 downward to reset the pressure cylinder 803, and the second tension spring is re- After the first motor 604 is newly stretched, the staff starts the first motor 604 to reverse the output shaft of the first motor 604, thereby driving the lower laminating frame 2 to move downward, and the lower laminating frame 2 moves downward to drive the lower laminating bracket 3 to move downward and reset through the sliding support frame 501, wherein the lower laminating frame 2 moves downward to make the second positioning frame 407 move synchronously, thereby contacting and squeezing the friction ring 406, so that the friction ring 406 drives the installation shell 404 to move through the rotating frame 403, and the installation shell 404 moves to drive the cleaning roller 405 to move back to the top laminated steel plate, and at the same time, the installation shell 404 moves to make the lower laminating frame 2 contact and squeeze the round head column 408 The round head column 408 moves to make the wedge block 409 move synchronously, and the first tension spring is stretched. The wedge block 409 moves to make the cutting knife 410 slide out of the mounting shell 404. The staff pulls the handrail 301 again to make the lower laminate bracket 3 repeat the forward movement. It is worth noting that if there is too much adhesive left on the polypropylene pad fabric, the excess adhesive will overflow from between the top laminate steel plate and the bottom laminate steel plate and form a colloid. Since the front side of the top laminate steel plate and the bottom laminate steel plate are squeezed by the lower laminate bracket 3 and the back side is squeezed by the driving frame 202, the overflowed colloid will only flow to the left and right sides, and the lower laminate bracket 3 moves forward. The colloid between the top laminated steel plate and the bottom laminated steel plate will be cut off by the cutting knife 410, thereby improving the quality of the polypropylene pad fabric, and the lower laminate bracket 3 moves forward to make the top laminated steel plate and the bottom laminated steel plate separate from the roller 504, so that the torsion spring is released to make the L-shaped frame 503 rotate and drive the roller 504 to reset, and at the same time, the top laminated steel plate moves forward to separate from the cleaning roller 405, at this time the first compression spring is released to make the scraper 412 push the cleaning roller 405 to reset, the staff will take out the bottom laminated steel plate, the polypropylene pad fabric and the top laminated steel plate at the same time, and push the handrail 301, so that the lower laminate bracket 3 repeats the above-mentioned reset action to complete the reset of the device.
