DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-4 This application is described in further detail.

[0023] The present application embodiment discloses a die-cut material thermal bonding device. Figure 1 The die-cutting material thermal bonding device includes a frame 1 and a mounting frame 2, wherein the mounting frame 2 is fixedly arranged on the frame 1, and the number of the mounting frames 2 can be set as needed, and an ordinary laminating roller and a heating laminating roller are installed on the mounting frame 2, wherein the heating laminating roller is adjusted in distance from the ordinary laminating roller by a height control component, the height control component is electrically connected to an external controller, and the temperature of the heating laminating roller is controlled by a temperature control system; an energy consumption management module is arranged on the frame 1, and the energy consumption management module is electrically connected to the main power supply, and the driving source of the ordinary laminating roller, the driving source of the heating laminating roller, the temperature control system and the height control component are all electrically connected to the energy consumption management module to monitor and optimize the energy consumption of the entire system.

[0024] Reference Figure 1 and Figure 2, a plurality of brackets 3 are fixedly arranged on the frame 1, and the brackets 3 correspond to the material strips entering between the ordinary pressing roller and the heated pressing roller one by one. The bracket 3 is a door-shaped bracket, and an abutting roller 4 for abutting the corresponding material strip is rotatably arranged on the bracket 3, and the rotation axis of the abutting roller 4 is perpendicular to the conveying direction of the corresponding material strip. A mounting plate 7 is slidably arranged on the bracket 3, and the sliding direction of the mounting plate 7 is perpendicular to the plane where the corresponding material strip is located. The cross section of the mounting plate 7 is U-shaped, and a plurality of guide rods 27 are fixed on the side of the mounting plate 7 away from the abutting roller 4. The guide rods 27 are slidably penetrated on the corresponding bracket 3, which helps to guide the sliding of the mounting plate 7; an extrusion roller 5 is rotatably arranged on the side of the mounting plate 7 close to the abutting roller 4, and the rotation axis of the extrusion roller 5 is parallel to the rotation axis of the abutting roller 4. The abutting roller 4 and the extrusion roller 5 are respectively located on the opposite sides of the corresponding material strip, and an elastic member is arranged on the bracket 3 for driving the mounting plate 7 to drive the extrusion roller 5 to slide in the direction close to the corresponding abutting roller 4. Reference Figure 2 A distance meter 6 for measuring the distance between the squeezing roller 5 and the abutting roller 4 is installed on the inner wall of the mounting plate 7, and a side of the mounting plate 7 close to the abutting roller 4 is flush with the edge of the squeezing roller 5 close to the abutting roller 4; the distance meter 6 is aligned with the mounting plate 7, and a side of the distance meter 6 close to the mounting plate 7 is flush with the edge of the abutting roller 4 close to the squeezing roller 5. The distance meter 6 is electrically connected to an external controller, and the distance meter 6 measures the distance between the distance meter 6 and the mounting plate 7 to obtain the distance between the squeezing roller 5 and the abutting roller 4.

[0025] When in use, the material strip first passes through the corresponding abutment roller 4 and squeezing roller 5, and then enters between the ordinary pressing roller and the heated pressing roller. Since the squeezing roller 5 and the abutment roller 4 can rotate with the movement of the material strip, the resistance to the material strip transmission can be reduced; under the action of the elastic member, the mounting plate 7 will drive the corresponding squeezing roller 5 to slide in the direction close to the abutment roller 4, so that the squeezing roller 5 and the abutment roller 4 clamp the corresponding material strip, and the distance between the squeezing roller 5 and the abutment roller 4 is measured by the distance meter 6 and sent to the external controller. The external controller receives the distance value and obtains the thickness of the corresponding material strip. The external controller drives the height control member to adjust the heated pressing roller to a suitable position according to the thickness of each material strip, so as to adjust the pressure applied by the heated pressing roller according to the thickness of the material strip entering between the ordinary pressing roller and the heated pressing roller, which helps to ensure the thermal bonding effect. At the same time, for strips of different materials and hardness, the thickness of the strip under extrusion can be obtained under the extrusion of the extrusion roller 5 and the contact roller 4, so as to adjust the pressure applied by the heating pressing roller to a suitable value according to the thickness and material of the material to ensure the thermal bonding effect. During the continuous conveying process of the strip, the rangefinder 6 can monitor the thickness of the strip in real time, so as to adjust the applied pressure in time for uneven strips, and at the same time eliminate the gaps and bubbles of the strips that have been bonded in the previous process.

[0026] Reference Figure 2In order to facilitate driving the mounting plate 7 to drive the squeezing roller 5 to slide in the direction close to the corresponding abutting roller 4, the elastic member includes a first spring 8, the first spring 8 corresponds to the guide rod 27 one by one, the first spring 8 is movably sleeved on the corresponding guide rod 27, the extension direction of the first spring 8 is parallel to the sliding direction of the mounting plate 7, one end of the first spring 8 is fixed to the side of the bracket 3 away from the abutting roller 4, and the other end is fixed to the side of the corresponding mounting plate 7 away from the abutting roller 4, when the squeezing roller 5 abuts against the abutting roller 4, the first spring 8 is in a compressed state.

[0027] Since the first spring 8 is always in a compressed state, it always exerts a pushing force on the mounting plate 7 toward the abutment roller 4, so that the squeezing roller 5 and the abutment roller 4 can extrude the corresponding material strip, which helps to adjust the pressure applied by the heating pressing roller to the required value according to the material and thickness of the material to ensure the effect of thermal bonding; at the same time, it can also eliminate gaps and bubbles in the bonded material strip in the previous process.

[0028] Reference Figure 2 and Figure 3 First fixing plates 21 are fixed to the outer walls on opposite sides of the bracket 3, and the arrangement direction of the two first fixing plates 21 is parallel to the rotation axis of the abutting roller 4. Fixed rods 22 are fixed on the two first fixing plates 21, and the length direction of the fixing rods 22 is parallel to the sliding direction of the mounting plate 7.

Second fixing plates 23 are fixed on opposite sides of the mounting plate 7, and the second fixing plates 23 are slidably penetrated on the bracket 3. Openings 26 for sliding of the second fixing plates 23 are provided on opposite sides of the bracket 3. The second fixing plates 23 correspond to the first fixing plates 21 one by one, and the second fixing plates 23 are located on the side of the first fixing plate 21 close to the squeezing roller 5. Abutment blocks 24 are fixed on the second fixing plates 23, and the abutment blocks 24 are aligned with the corresponding push rods 9. The push rods 9 are located on the side of the corresponding abutment blocks 24 close to the abutment roller 4. An adjusting component is provided on the first fixing plate 21, and the adjusting component is used to adjust the push rod 9 to push the abutment block 24 when the squeezing roller 5 abuts against the abutment roller 4, so as to drive the mounting plate 7 to slide in a direction away from the abutment roller 4.

[0029] Reference Figure 2 and Figure 3In order to facilitate the abutment of the squeezing roller 5 with the abutment roller 4, the push rod 9 is adjusted to push the abutment block 24 to drive the mounting plate 7 to slide in the direction away from the abutment roller 4. The adjustment component includes a first Velcro 10, a second Velcro 11, a first adsorption member and a pushing member. The first Velcro 10 is fixed to the side of the push rod 9 away from the mounting plate 7, and the second Velcro 11 is fixed to the first fixing plate 21. The first Velcro 10 is used to be bonded and matched with the second Velcro 11. When the first Velcro 10 is bonded and matched with the second Velcro 11, the push rod 9 is in a disengaged state from the abutment block 24 on the mounting plate 7; a suspension rod 25 is fixed to the side of the second fixing plate 23 close to the push rod 9, and the suspension rod 25 is located opposite to the push rod 9. The abutment block 24 should be on the side away from the mounting plate 7, and a sliding block 15 is passed through the suspension rod 25. The sliding block 15 is located between the abutment block 24 and the first fixed plate 21. The first adsorption member is arranged on the side of the sliding block 15 close to the first fixed plate 21. The first adsorption member is used to adsorb the push rod 9 to slide toward the mounting plate 7. The adsorption force of the first adsorption member is greater than the adhesion force between the first Velcro 10 and the second Velcro 11. When the extrusion roller 5 abuts the abutment roller 4, the first adsorption member is started; the pushing member is arranged on the first fixed plate 21, and the pushing member is used to push the push rod 9 to slide toward the mounting plate 7. The thrust of the pushing member is greater than the sum of the thrusts of the multiple first springs 8.

[0030] Reference Figure 2 , Figure 3 and Figure 4 In order to facilitate the adsorption of the push rod 9 and slide in the direction close to the mounting plate 7, the first adsorption component includes a first magnet 12 and a second magnet 13. The first magnet 12 is embedded on the side of the sliding block 15 close to the first fixed plate 21, and the second magnet 13 is fixed on the side of the push rod 9 close to the mounting plate 7. The first magnet 12 is used to adsorb the second magnet 13 to drive the push rod 9 to slide in the direction close to the mounting plate 7. The adsorption force between the first magnet 12 and the second magnet 13 is greater than the adhesion force between the first Velcro 10 and the second Velcro 11. When the extrusion roller 5 abuts against the abutment roller 4, the first magnet 12 has an adsorption force on the second magnet 13.

[0031] Reference Figure 2 and Figure 3 In order to facilitate the push rod 9 to slide toward the direction close to the mounting plate 7, the push member includes a second spring 14, which is movably mounted on the fixing rod 22, one end of the second spring 14 is fixed on the push rod 9, and the other end is fixed on the first fixing plate 21.

[0032] When the material strip is being conveyed, the first Velcro 10 on the push rod 9 is bonded and matched with the second Velcro 11 on the first fixed plate 21, the second spring 14 is in a compressed state, and the push rod 9 is located on the side of the squeezing roller 5 close to the abutting roller 4; when the material strip is conveyed, the mounting plate 7 drives the squeezing roller 5 to slide in the direction close to the abutting roller 4 under the push of the first spring 8, so that the second fixed plate 23 drives the abutting block 24 and the suspension rod 25 to synchronously approach the push rod 9 until the squeezing roller 5 abuts against the abutting roller 4. At this time, the first magnet 12 on the sliding block 15 has an adsorption effect on the second magnet 13 on the push rod 9, and the large Due to the adhesion force between the first Velcro 10 and the second Velcro 11, the first magnet 12 absorbs the second magnet 13 and drives the push rod 9 to slide toward the direction close to the mounting plate 7, so that the first Velcro 10 and the second Velcro 11 are separated, and then the push rod 9 slides toward the direction close to the mounting plate 7 under the thrust of the second spring 14, and then the push rod 9 pushes the abutment block 24 to drive the mounting plate 7 to slide in the direction away from the abutment roller 4, so that the squeezing roller 5 and the abutment roller 4 are separated, so that the material belt can pass between the squeezing roller 5 and the abutment roller 4 when used next time, which provides convenience for the operator to lay the material.

[0033] Reference Figure 2 and Figure 3 The sliding block 15 is slidably arranged on the suspension rod 25, and the sliding direction of the sliding block 15 is perpendicular to the sliding direction of the mounting plate 7. Specifically, the sliding direction of the sliding block 15 is parallel to the rotation axis of the abutting roller 4. A third magnet 16 is fixedly arranged on the outer wall of the bracket 3, and the third magnet 16 is located on the side of the abutting block 24 away from the suspension rod 25. A fourth magnet 17 is fixed on the sliding block 15 for adsorbing and cooperating with the third magnet 16 to drive the sliding block 15 to slide. When the squeezing roller 5 abuts the abutting roller 4, the fourth magnet 17 is aligned with the third magnet 16; when the fourth magnet 17 is adsorbed and cooperated with the third magnet 16, the first magnet 12 is aligned with the second magnet 13; when the third magnet 16 is misaligned with the fourth magnet 17, the first magnet 12 is misaligned with the second magnet 13.

[0034] Reference Figure 2 and Figure 3The suspension rod 25 is provided with a reset member for pushing the sliding block 15 to slide in a direction away from the third magnet 16. The reset member includes a third spring 19, which is sleeved on the side of the sliding block 15 away from the third magnet 16. One end of the third spring 19 is fixed on the side of the sliding block 15 away from the third magnet 16, and the other end is fixed on the suspension rod 25. The elastic force of the third spring 19 is less than the elastic force of the second spring 14. The side of the sliding block 15 close to the third magnet 16 is an arc surface, and the side of the arc surface close to the third magnet 16 is inclined in a direction away from the first fixed plate 21. The side of the push rod 9 close to the third magnet 16 is fixed with a separator 18, which is used to slide relative to the arc surface of the sliding block 15. The distance from the side of the separator 18 close to the mounting plate 7 to the center line of the squeezing roller 5 is less than the distance from the side of the push rod 9 close to the mounting plate 7 to the center line of the squeezing roller 5. When the first Velcro 10 and the second Velcro 11 are bonded and matched, the separator 18 is located on the side of the third magnet 16 away from the mounting plate 7.

[0035] Reference Figure 2 and Figure 3 A partition plate 20 is fixed on the outer wall of the bracket 3. The cross section of the partition plate 20 is U-shaped. The partition plate 20 is located between the abutment block 24 and the suspension rod 25. The push rod 9 is located on the side of the partition plate 20 close to the third magnet 16. The side of the third magnet 16 close to the mounting plate 7 is flush with the side of the partition plate 20 close to the abutment roller 4. When the third magnet 16 and the fourth magnet 17 are misaligned, the sliding block 15 is located on the side of the partition plate 20 away from the third magnet 16. The setting of the partition plate 20 prevents the fourth magnet 17 on the sliding block 15 from being adsorbed and connected with the third magnet 16 in advance, so as to ensure that the fourth magnet 17 can be adsorbed and matched with the third magnet 16 only when the abutment roller 4 and the squeezing roller 5 are in abutment.

[0036] When there is a gap between the squeezing roller 5 and the abutting roller 4, the sliding block 15 cannot slide in the direction close to the third magnet 16 under the action of the partition plate 20. Only when the squeezing roller 5 abuts against the abutting roller 4 can the fourth magnet 17 be completely aligned with the third magnet 16, and the third magnet 16 absorbs the fourth magnet 17 to drive the sliding block 15 to slide in the direction close to the push rod 9. Then the first magnet 12 is aligned with the second magnet 13, and the first magnet 12 absorbs the second magnet 13 to slide in the direction close to the mounting plate 7, so that the first Velcro 10 and the second Velcro 11 is disengaged, the push rod 9 moves toward the mounting plate 7 under the thrust of the second spring 14, and then the partition sheet 18 and the arc surface of the sliding block 15 slide relative to each other to push the sliding block 15 to move in the direction away from the third magnet 16, so that the third magnet 16 is disengaged from the fourth magnet 17, and then the sliding block 15 is reset under the action of the third spring 19, the first magnet 12 is misaligned with the second magnet 13, the second spring 14 pushes the push rod 9 to move and abut against the abutment block 24, and the push rod 9 pushes the abutment block 24 to move, thereby realizing the disengagement of the squeezing roller 5 and the abutment roller 4.

[0037] The implementation principle of the embodiment of the present application is as follows: when in use, the material strip first passes through between the corresponding abutment roller 4 and the squeezing roller 5, and then pushes the push rod 9 in the direction close to the first fixed plate 21, so that the first Velcro 10 and the second Velcro 11 are bonded and matched. After the push rod 9 is disengaged from the abutment block 24, the mounting plate 7 drives the squeezing roller 5 to abut the material strip against the abutment roller 4 under the action of the first spring 8, and then the material strip enters between the ordinary pressing roller and the heated pressing roller. When the material strip moves during transmission, it will drive the squeezing roller 5 and the abutment roller 4 to rotate; the distance between the squeezing roller 5 and the abutment roller 4 is measured by the distance meter 6 and sent to the external controller, the external controller receives the distance value, and obtains the thickness of the corresponding material strip. The external controller drives the height control component to adjust the position of the heated pressing roller according to the extrusion thickness of each material strip, so as to facilitate the adjustment of the pressure applied by the heated pressing roller according to the thickness and material of the material strip, which helps to ensure the heat bonding effect and can eliminate the gaps and bubbles in the bonded material strips in the previous process.

[0038] When the material belt is transmitted, it proves that the processing is completed. Since there is no gap between the material belts, the mounting plate 7 drives the extrusion roller 5 to slide in the direction close to the abutment roller 4 under the push of the first spring 8, and the second fixed plate 23 synchronously drives the abutment block 24 and the suspension rod 25 close to the push rod 9 until the extrusion roller 5 abuts against the abutment roller 4. At this time, the fourth magnet 17 on the sliding block 15 is misaligned with the partition plate 20 and is completely aligned with the third magnet 16. Then the third magnet 16 absorbs the fourth magnet 17 to drive the sliding block 15 to move in the direction close to the push rod 9, so that the third magnet 16 and the fourth magnet 17 are adsorbed and connected. At this time, the first magnet 12 on the sliding block 15 is aligned with the second magnet 13 on the push rod 9, and then the first magnet 12 absorbs the second magnet 13 to drive the push rod 9 to slide in the direction close to the mounting plate 7. The first Velcro 10 is disengaged from the second Velcro 11, and the push rod 9 slides toward the direction close to the mounting plate 7 under the thrust of the second spring 14, and then the separator 18 and the arc surface of the sliding block 15 slide relative to each other, and the abutting sliding block 15 moves in the direction away from the third magnet 16, so that the fourth magnet 17 is disengaged from the third magnet 16, and then the sliding block 15 is reset under the action of the third spring 19 and is staggered with the abutting block 24 again, and then the push rod 9 continues to move and abuts against the abutting block 24, and the push rod 9 pushes the abutting block 24 under the thrust of the second spring 14 to drive the mounting plate 7 to slide in the direction away from the abutting roller 4, so that the squeezing roller 5 is disengaged from the abutting roller 4, so that it is convenient for the material belt to pass between the squeezing roller 5 and the abutting roller 4 when used next time, providing convenience for the operator to cloth.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
