Description

Technical Field

[0001] The invention relates to the technical field of film coating, and in particular to an environmentally friendly rubber self-adhesive coil film coating device. Background Art

[0002] Waterproof membrane is a commonly used building material used in water conservancy projects, underground projects and roof protection projects. It is mostly made of a composite base made of EPDM or butyl rubber and modified asphalt. The upper layer of the composite base uses high-density polyethylene film or aluminum foil, which has the advantages of corrosion resistance, high strength and aging resistance.

[0003] According to patent No. CN114347629A, publication (announcement) date: 2022-04-15, a self-adhesive polymer modified asphalt waterproofing membrane coating device is disclosed, and the self-adhesive polymer modified asphalt waterproofing membrane coating device includes: a box body, and a coating assembly is rotatably connected to the middle part of the box body; a tensioning mechanism is rotatably connected to the middle part of the box body and rotatably cooperates with the coating assembly; a transmission assembly is rotatably connected to both sides of the box body; a pressing assembly is slidably connected to the inside of the box body; a linkage assembly is rotatably connected to one end of the outside of the box body; when the device is coating the membrane body, the tensioning mechanism can keep the membrane material in a tensioned state at all times, avoiding the loosening of the membrane material due to the reduction of the membrane material, so that the membrane material and the processing material can be perfectly fitted, and bubbles generated by the membrane material and the processing material during the coating process can be removed, thereby improving the degree of fit between the membrane material and the processing material, and achieving a perfect fit effect.

[0004] In the prior art including the above-mentioned patent, a removable isolation film is covered on the composite base to prevent the composite base from losing its stickiness due to air drying. However, the isolation film is stretched and adhered to the composite base. However, the thickness at the edges is uneven due to the extension of the composite base during the pressing process, so that small gaps will still appear at the edges. This can easily lead to the situation where the roll material is placed for a long time after production and then used. Due to the small gaps, air can leak in and the edges will curl up when it is air-dried and then adhered for use. Summary of the invention

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0037] like Figure 1-9 As shown, an environmentally friendly rubber self-adhesive coil laminating device comprises:

[0038] A semi-finished product roll, which includes a composite tire base 41 and an upper film 5 that are bonded to each other;

[0039] Isolation film 6;

[0040] The outward expansion pressing roller group 1 comprises a first pressing part 11 and outward expansion columns 12 rotatably arranged at both ends of the first pressing part 11, and the outward expansion columns 12 are provided with threaded strips;

[0041] The auxiliary pressing roller and the outer pressing roller group 1 are clamped to form a pressing space, the isolation film 6 and the semi-finished product roll are attached and pass through the pressing space, and the upper film 5 is attached to the auxiliary pressing roller;

[0042] The first pressing part 11 is driven to rotate and drives the outer expansion column 12 times to rotate, so that the threaded strips squeeze the two sides of the isolation membrane 6.

[0043] Specifically, the isolation film 6 is a coiled material, and the coiled isolation film 6 is arranged on the supporting roller 42. The outer pressing roller group 1 and the auxiliary pressing roller are axially parallel and in the same vertical plane, so that the auxiliary pressing roller and the outer pressing roller group 1 are clamped to form a pressing space, and the semi-finished roll and the isolation film 6 are passed through the pressing space, and the upper film 5 is attached to the auxiliary pressing roller, and the outer pressing roller group 1 is attached to the isolation film 6 for pressing. During the pressing, the first pressing part 11 is driven to rotate to cooperate with the auxiliary pressing roller to press the semi-finished roll and the isolation film 6, and the auxiliary pressing roller is used to press the semi-finished roll and the isolation film 6. The two are fitted together, and at the same time, the outward expansion column 12 will rotate at a speed twice that of the first pressing part 11, so that the threaded strips on the outward expansion column 12 will squeeze the two sides of the isolation membrane 6, so as to push the middle composite tire base 41 to both sides along with the threaded strips, thereby filling the gap between the edge of the isolation membrane 6 and the composite tire base 41, so that the gap at the edge of the finished coil 4 output after extrusion is filled, which can reduce the contact with the air when placed after production, thereby reducing the situation of air drying, and thus reducing the situation of warping when applying.

[0044] Furthermore, when self-adhesive rolls of different specifications are produced, additional glue can be squeezed on both sides of the semi-finished roll in the step of laminating the isolation film 6 and the semi-finished roll, so that the thread strips can push the glue to spread when squeezed, which can also reduce the edge warping during laminating.

[0045] In the above technical solution, when pressing the isolation film 6, the first pressing part 11 on the external pressing roller group 1 is driven to cooperate with the auxiliary pressing roller to press the semi-finished roll and the isolation film 6 to achieve preliminary bonding. At the same time, the external expansion columns 12 on both sides will rotate at a speed twice that of the first pressing part 11 to squeeze the semi-finished roll and the isolation film 6 at the edge through the threaded strips, so that the composite tire base 41 is extended to fill the edge gap and prevent it from drying out.

[0046] As an embodiment provided by the present invention, the external expansion pressing roller group 1 also includes a fixed shaft 14, and connecting sleeves 113 and gear bins 112 are provided at both ends of the first pressing part 11. A planetary gear 114 is rotatably connected in the gear bin 112, and the connecting sleeve 113 is rotatably connected to the fixed shaft 14. A sun gear that is fixedly provided on the fixed shaft 14 and coupled to the planetary gear 114, and an outer gear ring 122 that is coupled to the planetary gear 114 is provided on the external expansion column 12.

[0047] Specifically, the fixed shaft 14 is fixed on the frame (the frame is an aluminum profile frame or a cast iron frame), the connecting sleeve 113 is rotatably connected to the fixed shaft 14 for rotation, a planetary rotating column 1121 is arranged in a circular array in the gear bin 112, and the planetary gear 114 is rotatably connected to the planetary rotating column 1121. A sun gear is fixed on the fixed shaft 14, and the sun gear is arranged in the gear bin 112 to couple with the planetary gear 114 to cooperate with the planetary rotating column 1121 to drive the planetary gear 114 to rotate when the first pressing part 11 rotates. An outer ring gear 122 coupled to the planetary gear 114 is arranged on the outer expansion column 12. When the planetary gear 114 rotates, it will drive the outer ring gear 122 to rotate at a times speed, thereby driving the outer expansion column 12 to rotate, thereby realizing a faster rotation of the outer expansion column 12 relative to the first pressing part 11.

[0048] Furthermore, a motor is arranged on the frame, and a transmission belt is arranged between the output end of the motor and the connecting sleeve 113, thereby driving the first pressing part 11 to rotate.

[0049] During pressing, the motor drives the transmission belt to rotate, thereby driving the first pressing part 11 to rotate, so as to cooperate with the auxiliary pressing roller to press the semi-finished product roll and the isolation film 6, and assist the two to fit together. At the same time, the planetary rotating column 1121 acts as a planetary carrier to drive the planetary gear 114 to rotate, and drives the outer gear ring 122 to rotate at a times speed, so that the outer expansion column 12 will rotate at a speed twice that of the first pressing part 11, so that the threaded strips on the outer expansion column 12 will squeeze the two sides of the isolation film 6, so as to push the middle composite tire base 41 to both sides along with the threaded strips, thereby filling the gap between the edge of the isolation film 6 and the composite tire base 41.

[0050] As an embodiment provided by the present invention, a friction shaft 13 which rotates synchronously with the outer expansion column 12 is provided on the first pressing part 11, and the thread strip on the outer expansion column 12 is an elastic thread sleeve 121, and the elastic thread sleeve 121 includes the following two stations:

[0051] First station: the isolation membrane 6 is driven to tension and pull the friction shaft 13 to limit, so as to drive the elastic threaded sleeve 121 to reduce the pitch;

[0052] The second working position: the isolation membrane 6 reduces the restriction on the friction shaft 13 to drive the elastic threaded sleeve 121 to increase the pitch.

[0053] Specifically, a transfer groove 111 is provided at the center of the first pressing part 11, and the friction shaft 13 is rotatably connected to the transfer groove 111. The friction shaft 13 and the first pressing part 11 are attached to the isolation film 6 together. When the isolation film 6 is set, it will be tensioned by the support roller 42 to control the tension of the isolation film 6 along the transportation direction. When the tensioning force is high, the isolation film 6 is not easy to wrinkle. At this time, the elastic threaded sleeve 121 is in the first position, and the friction shaft 13 is pulled and restricted by the tensioned isolation film 6, so that the misalignment angle between the friction shaft 13 and the outer expansion column 12 is increased, so as to drive the elastic threaded sleeve 121 to reduce the pitch. The smaller the tension force, the smaller the extrusion range of the threaded strip in a single rotation. This corresponds to a larger tensioning force, which prevents the threaded strip from being unable to push the composite tire base 41 to deform due to excessive tensioning force. When the tensioning force of the isolation membrane 6 is low, the limiting force of the isolation membrane 6 on the friction shaft 13 is reduced, so that the friction shaft 13 switches to the second working position, and the misalignment angle between the friction shaft 13 and the outer expansion column 12 increases and decreases, so as to drive the elastic threaded sleeve 121 to recover. Compared with high tension, the pitch increases, so that the extrusion range of the threaded strip in a single rotation is increased. Corresponding to the situation of smaller tensioning force, it is pushed by a long pitch.

[0054] During pressing, the motor drives the transmission belt to rotate, thereby driving the first pressing part 11 to rotate, so as to cooperate with the auxiliary pressing roller to press the semi-finished product roll and the isolation film 6 to assist the two to fit together. At the same time, when the tension of the isolation film 6 is high, the friction shaft 13 drives the elastic threaded sleeve 121 to reduce the pitch; when the tension of the isolation film 6 is low, the friction shaft 13 drives the elastic threaded sleeve 121 to increase the pitch; the planetary rotating column 1121 acts as a planetary carrier to drive the planetary gear 114 to rotate, driving the outer gear ring 122 to rotate at a times speed, so that the outer expansion column 12 will rotate at a speed twice that of the first pressing part 11, so that the threaded strips on the outer expansion column 12 will squeeze the two sides of the isolation film 6, so as to push the composite tire base 41 in the middle to both sides along with the threaded strips, thereby filling the gap between the edge of the isolation film 6 and the composite tire base 41.

[0055] As an embodiment provided by the present invention, a connecting strip 123 is slidably connected to the outer gear ring 122, and a first end of the connecting strip 123 is arranged on the elastic threaded sleeve 121. A coupling ring 15 is fixedly connected to the friction shaft 13 through a spring 153, and elastic teeth 151 are arranged in a circumferential array on the coupling ring 15. The connecting strip 123 pushes against the elastic teeth 151 to rotate;

[0056] The elastic tooth 151 is provided with a bending portion 152 , and a rotating cavity for the spring 153 and the coupling ring 15 to rotate is opened in the first pressing portion 11 . A connecting column 150 is provided in the rotating cavity, and the elastic tooth 151 bends along the connecting column 150 as it rotates.

[0057] Specifically, the first end of the connecting bar 123 (with Figure 6For reference, the first end is the left end and the second end is the right end) is arranged on the elastic threaded sleeve 121. When the first pressing part 11 is driven to rotate, the elastic threaded sleeve 121 will be driven to rotate. At this time, the fitting plate 124 arranged on the second end of the connecting strip 123 will rotate to push the elastic tooth 151, thereby driving the coupling ring 15 to rotate, and the coupling ring 15 drives the friction shaft 13 to rotate, so that the rotation speed of the friction shaft 13 is the same as that of the elastic threaded sleeve 121. When the tensioning force of the isolation membrane 6 is high, the friction between the isolation membrane 6 and the friction shaft 13 will also increase with the increase of the tensioning pressure, so that the spring 153 will twist and tighten to pull the elastic threaded sleeve 121, thereby shortening the pitch. When the tensioning force of the isolation membrane 6 is low, the friction between the isolation membrane 6 and the friction shaft 13 is reduced, and the reduced friction is not enough to cause the spring 153 to shorten, so that the elastic threaded sleeve 121 rebounds relative to the high tension. The pitch increases.

[0058] Furthermore, the bending portion 152 is used to pull the bonding plate 124 to move, and a connecting column 150 is provided in the rotating cavity. When the elastic tooth 151 is driven to rotate, it will be hindered by the connecting column 150 to bend, and rebound after passing over the connecting column 150 and re-bond the bonding plate 124. There are two connecting strips 123, so that when the elastic tooth 151 of one of them is bent, the other one continues to bond.

[0059] During pressing, the motor drives the transmission belt to rotate, thereby driving the first pressing part 11 to rotate, so as to cooperate with the auxiliary pressing roller to press the semi-finished product roll and the isolation film 6 to assist the two to fit together. At the same time, when the tension of the isolation film 6 is high, the friction between the isolation film 6 and the friction shaft 13 will also increase with the increase of the tension pressure, so that the spring 153 will twist and tighten to pull the elastic threaded sleeve 121. When the tension of the isolation film 6 is low, the friction between the isolation film 6 and the friction shaft 13 is reduced, and the reduced friction The force is not enough to shorten the spring 153, so that the elastic threaded sleeve 121 rebounds and the pitch increases relative to when the tension force is high. The planetary rotating column 1121 acts as a planetary carrier to drive the planetary gear 114 to rotate, and drives the outer gear ring 122 to rotate at a times speed, so that the outer expansion column 12 will rotate at a speed twice that of the first pressing part 11, so that the thread strips on the outer expansion column 12 will squeeze the two sides of the isolation membrane 6, so as to squeeze the composite tire base 41 in the middle to both sides along with the thread strips, thereby filling the gap between the edge of the isolation membrane 6 and the composite tire base 41.

[0060] As an embodiment provided by the present invention, it also includes a diaphragm tensioning roller 3 for tensioning the isolation membrane 6. Rubber contacts 321 are arranged on both sides of the diaphragm tensioning roller 3. The rubber contacts 321 rotate and move axially with the rotation of the diaphragm tensioning roller 3 to pull the isolation membrane 6.

[0061] Specifically, the diaphragm tensioning roller 3 is used to pre-expand the isolation membrane 6 when it is pulled out from the coil for use, so as to reduce the occurrence of wrinkles on the isolation membrane 6. Rubber contacts 321 are provided on both sides of the diaphragm tensioning roller 3. When the isolation membrane 6 is attached to the diaphragm tensioning roller 3, as the isolation membrane 6 rotates, the rubber contacts 321 will move toward the axial direction of the diaphragm tensioning roller 3 to pull the isolation membrane 6 in the axial direction, thereby reducing the occurrence of wrinkles in the axial direction.

[0062] When the isolation film 6 is pulled out from the isolation roll, it will pass through the isolation film tensioning roller 3. At this time, the rubber contact 321 will move toward the axial direction of the isolation film tensioning roller 3 to pull the isolation film 6 in the axial direction. Then, during pressing, the motor drives the transmission belt to rotate, thereby driving the first pressing part 11 to rotate, so as to cooperate with the auxiliary pressing roller to press the semi-finished roll and the isolation film 6 to assist in fitting the two. At the same time, the planetary rotating column 1121 acts as a planetary carrier to drive the planetary gear 114 to rotate, and drives the outer gear ring 122 to rotate at a times speed, so that the outer expansion column 12 will rotate at a speed twice that of the first pressing part 11, so that the threaded strips on the outer expansion column 12 will squeeze the two sides of the isolation film 6, so as to push the middle composite tire base 41 to both sides along with the threaded strips, thereby filling the gap between the edge of the isolation film 6 and the composite tire base 41.

[0063] As an embodiment provided by the present invention, the diaphragm tensioning roller 3 includes a central shaft 32 and an outer sleeve 31 sleeved on the central shaft 32, and the central shaft 32 is rotatably connected with an outward expansion column 12 on both sides, and the rubber contact 321 is arranged on the outward expansion column 12, and the rubber contact 321 extends out of the spiral groove 311 on the outer sleeve 31.

[0064] Specifically, the outward expansion column 12 on the central shaft 32 has the same mechanism as the outward expansion column 12 on the outward pressing roller group 1 for achieving double speed, but the outward expansion column 12 on the central shaft 32 cannot be deformed, and the rubber contact 321 is arranged on the threaded strip of the outward expansion column 12 to move spirally along the spiral groove 311 as it rotates.

[0065] When the isolation film 6 is pulled out from the isolation roll, it will pass through the isolation film tensioning roller 3. At this time, the rotation of the central axis 32 and the rotation of the outer expansion column 12 at a times speed drive the rubber contact 321 to move spirally, so that the rubber contact 321 will move toward the axial direction of the diaphragm tensioning roller 3 to pull the isolation film 6 in the axial direction. Then, during pressing, the motor drives the transmission belt to rotate, thereby driving the first pressing part 11 to rotate, so as to cooperate with the auxiliary pressing roller to press the semi-finished roll and the isolation film 6 to assist in the fitting of the two. At the same time, the planetary rotating column 1121 acts as a planetary carrier to drive the planetary gear 114 to rotate, and drives the outer gear ring 122 to rotate at a times speed, so that the outer expansion column 12 will rotate at a speed twice that of the first pressing part 11, so that the threaded strips on the outer expansion column 12 will squeeze the two sides of the isolation film 6, so as to push the middle composite tire base 41 to both sides along with the extrusion of the threaded strips, thereby filling the gap between the edge of the isolation film 6 and the composite tire base 41.

[0066] As an embodiment provided by the present invention, it also includes a tire membrane pressing roller 2, a symmetrical cooling pressing roller 7 and an output die 71. The output die 71 extrude the composite tire base 41 and is plasticized by the cooling pressing roller 7 and then pressed with the upper membrane 5 through the tire membrane pressing roller 2 and the auxiliary pressing roller;

[0067] The fetal membrane pressing roller 2 includes a second pressing portion 21 and protruding blocks 22 arranged on both sides of the second pressing portion 21 .

[0068] Specifically, the diaphragm pressing roller 2 is used to press the upper membrane 5 and the composite tire base 41 extruded from the output die 71. The cooling pressing roller 7 is connected to the coolant, which can plasticize and cool the composite tire base 41 extruded from the output die 71. The diaphragm pressing roller 2 includes a second pressing portion 21 and raised blocks 22 arranged on both sides of the second pressing portion 21. When rotating, the diaphragm pressing roller 2 will cooperate with the auxiliary pressing roller to press the upper membrane 5 and the composite tire base 41. While pressing, the raised blocks 22 on both sides will assist in bonding the upper membrane 5 and the composite tire base 41 at the extruded edge.

[0069] During production, the composite tire base 41 is first extruded by the output die head 71, and then the cooling pressing roller 7 plasticizes and cools the composite tire base 41. Then, the tire membrane pressing roller 2 cooperates with the auxiliary pressing roller to press the upper film 5 and the composite tire base 41. During the pressing, the raised blocks 22 on both sides will assist in the adhesion of the upper film 5 and the composite tire base 41 at the extrusion edge. When the isolation film 6 is pulled out from the isolation roll, it will pass through the diaphragm tensioning roller 3. At this time, the rotation of the central shaft 32 and the 12-fold rotation of the outer expansion column drive the spiral movement of the rubber contact 321, so that the rubber contact 321 will move toward the axial direction of the diaphragm tensioning roller 3 to move in the axial direction. The isolation film 6 is pulled, and then during pressing, the motor drives the transmission belt to rotate, thereby driving the first pressing part 11 to rotate, so as to cooperate with the auxiliary pressing roller to press the semi-finished product roll and the isolation film 6, and assist the two to fit together. At the same time, the planetary rotating column 1121 acts as a planetary frame to drive the planetary gear 114 to rotate, and drives the outer gear ring 122 to rotate at a times speed, so that the outer expansion column 12 will rotate at a speed twice that of the first pressing part 11, so that the threaded strips on the outer expansion column 12 will squeeze the two sides of the isolation film 6, so as to push the middle composite tire base 41 to both sides along with the threaded strips, thereby filling the gap between the edge of the isolation film 6 and the composite tire base 41.

[0070] As the optimal embodiment provided by the present invention, outward expansion columns 12 are arranged on both sides of the second pressing part 21, and the protruding blocks 22 are arranged on the outward expansion columns 12. The outward expansion columns 12 rotate at a higher speed to drive the protruding blocks 22 to approach the second pressing part 21.

[0071] Specifically, the outward expansion columns 12 on both sides of the second pressing portion 21 will also rotate at double speed relative to the second pressing portion 21, and its double speed structure is the same as the structure of the outward expansion columns 12 on the outward pressing roller group 1, and the spiral bars of the outward expansion columns 12 on both sides of the second pressing portion 21 are opposite to the spiral directions of the spiral bars of the outward expansion columns 12 on the outward pressing roller group 1, so that the raised blocks 22 will approach the center (that is, the second pressing portion 21) as the fetal membrane pressing roller 2 rotates, thereby increasing the thickness of the middle part to cope with the subsequent extension of the outward pressing roller group 1.

[0072] During production, the composite tire base 41 is first extruded by the output die head 71, and then the cooling pressing roller 7 plasticizes and cools the composite tire base 41. Then, the tire membrane pressing roller 2 cooperates with the auxiliary pressing roller to press the upper film 5 and the composite tire base 41. During the pressing, the raised blocks 22 on both sides will move closer to the center as the tire membrane pressing roller 2 rotates, so as to assist in the adhesion of the upper film 5 and the composite tire base 41 at the extrusion edge. When the isolation film 6 is pulled out from the isolation roll, it will pass through the diaphragm tensioning roller 3. At this time, the rotation of the central shaft 32 and the 12-fold speed rotation of the outer expansion column drive the rubber contact 321 to move spirally, so that the rubber contact 321 will move toward the axis of the diaphragm tensioning roller 3. The motor drives the transmission belt to rotate during pressing, thereby driving the first pressing part 11 to rotate, so as to cooperate with the auxiliary pressing roller to press the semi-finished product roll and the isolation film 6, and assist in the bonding of the two. At the same time, the planetary rotating column 1121 acts as a planetary carrier to drive the planetary gear 114 to rotate, and drives the outer gear ring 122 to rotate at a times speed, so that the outer expansion column 12 will rotate at a speed twice that of the first pressing part 11, so that the threaded strips on the outer expansion column 12 will squeeze the two sides of the isolation film 6, so as to push the composite tire base 41 in the middle to both sides along with the threaded strips, thereby filling the gap between the edge of the isolation film 6 and the composite tire base 41.

[0073] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
