Description

Technical Field

[0001] This invention relates to the field of laminating machines, and in particular to a hot press laminating machine. Background Technology

[0002] Laminating machines can be divided into two main categories: instant coating laminating machines and pre-coating laminating machines. Instant coating laminating machines apply the coating directly to the surface of the material and then solidify the coating on the surface of the material after hot pressing. Pre-coating laminating machines pre-apply the coating to a plastic film and then transfer the coating to the material through hot pressing. Usually, the film strip with the pre-coated coating is wound around a material cylinder to form a roll for storage and transportation.

[0003] Currently, laminating machines are mostly used for laminating flat products. When laminating products with multiple laminating surfaces, it is necessary to disassemble and reassemble the products multiple times to laminate different surfaces separately, which affects production efficiency. Therefore, there is a need for a laminating machine that can laminate multiple laminating surfaces of a product in one installation, thereby improving laminating efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a hot press laminating machine, which has the advantage of being able to laminate multiple laminating surfaces of the workpiece to be laminated in one installation, thereby improving laminating efficiency.

[0005] To achieve the above and other related objectives, the present invention provides the following technical solution: a hot press laminating machine, comprising:

[0006] Support base for holding workpieces to be coated;

[0007] A rotary drive device for driving the support base to rotate about a fixed axis to drive the workpiece to be coated to rotate.

[0008] A tape-supporting assembly for holding a pre-coated film tape and driving the film tape to move in a directional direction along its length.

[0009] A hot press roller that connects to an external power supply and, after heating, presses a film strip toward the workpiece to transfer the coating onto the workpiece.

[0010] A sliding drive device for driving the hot press roller to slide in a direction perpendicular to the axis of rotation of the support base; and,

[0011] The controller, pre-inputting the contour of the workpiece to be coated, controls the sliding drive device to drive the hot pressure roller to slide when the workpiece to be coated rotates or the distance between the coating position of the workpiece to be coated and the rotation axis of the support changes, so that the hot pressure roller always applies pressure to the workpiece to be coated.

[0012] With the above technical solution, the workpiece to be coated is installed on the support base during use. The controller controls the sliding drive device to drive the hot pressure roller to move and press the film belt supported by the material belt carrier assembly onto the workpiece to be coated. The external power supply device supplies power to the hot pressure roller. Then, the controller controls the rotation drive device to drive the workpiece to be coated to rotate. If the coating surface of the workpiece to be coated is not a regular arc shape when the workpiece to be coated rotates, the distance from the contact position between the hot pressure roller and the workpiece to the rotation axis of the workpiece to be coated will change. At this time, the controller controls the sliding drive device to drive the hot pressure roller to slide according to the pre-input contour information of the workpiece to be coated, so that the hot pressure roller always presses the film belt and the workpiece to be coated. In this way, the workpiece to be coated can be coated on multiple surfaces parallel to the rotation axis of the workpiece to be coated in one installation and fixation, thereby improving the coating efficiency.

[0013] In one embodiment of the present invention, the strip carrying assembly includes:

[0014] A mounting rod for holding film strip rolls; a take-up cylinder for recycling waste film strips after hot pressing; and a recycling drive for driving the take-up cylinder to rotate so that the waste film strips are wound around the take-up cylinder.

[0015] With the above technical solution, when in use, the roll of material containing the film belt is installed on the mounting rod, and the film belt is led out and the end of the film belt is fixed on the take-up cylinder. When the equipment is running, the film belt is moved by the retraction drive component while the hot press roller is hot pressing the film, so that the part of the film belt with pre-coated paint comes into contact with the workpiece to be coated.

[0016] In one embodiment of the present invention, the material strip bearing assembly further includes at least two pressure rollers disposed between the mounting rod and the hot press roller, the pressure rollers squeezing the film strip to tighten the film strip and maintain the film strip tension when the recycling drive drives the take-up cylinder to rotate.

[0017] Through the above technical solution, the pressure roller applies pressure to the film belt. When the recycling drive drives the take-up cylinder to rotate and make the film belt wrap around the take-up cylinder, the force applied by the take-up cylinder to the film belt needs to be greater than the frictional force of the pressure roller's rotation in order to drive the film belt. The film belt between the take-up cylinder and the pressure roller will be subjected to tension, causing the film belt between the take-up cylinder and the pressure roller to move along a specific route, thereby enhancing the stability of the equipment operation.

[0018] In one embodiment of the present invention, the material strip bearing assembly further includes at least two conforming rollers. When the hot pressure rollers press the film strip to transfer the coating onto the workpiece to be coated, the conforming rollers press the position of the film strip that is not in contact with the workpiece to be coated in a direction away from the pressure rollers to enhance the adhesion between the film strip and the workpiece to be coated.

[0019] By using the above technical solution, the two sides of the film strip are pressed towards the workpiece to be coated, so that the film strip adheres to the workpiece to be coated, thereby improving the stability during hot pressing and coating.

[0020] In one embodiment of the present invention, a sliding frame is further included, the strip bearing assembly and the hot press roller are mounted on the sliding frame, and the sliding drive device drives the sliding frame to slide.

[0021] The above technical solution enables the material strip mounting assembly and the hot press roller to slide synchronously, and further enables the film strip to slide synchronously with the hot press roller. As a result, when the hot press roller slides and adjusts its position relative to the workpiece to be coated, the relative position of the film strip and the hot press roller does not change, thus enhancing the stability of operation.

[0022] In one embodiment of the present invention, a heat insulation cover is further provided around the hot press roller and has an opening for the hot press roller to extend out. The hot press roller is rotatably connected to the heat insulation cover. An elastic element is connected between the heat insulation cover and the sliding frame. The elastic element deforms when the hot press roller is pressed to apply a reverse force to the heat insulation cover so that the hot press roller presses the workpiece to be coated.

[0023] Through the above technical solution, the heat insulation cover can block some of the heat loss of the hot pressure roller. At the same time, when the sliding drive device drives the sliding frame to slide towards the workpiece to be coated, the elastic element deforms when the hot pressure roller squeezes the workpiece to be coated, which plays a buffering role to prevent the workpiece to be coated from being deformed by pressure. At the same time, the pressure is transmitted to the workpiece to be coated through the elastic element, which can enhance the stability of the workpiece to be coated under pressure and improve the coating quality.

[0024] In one embodiment of the present invention, a modeling component is further included for measuring the contour of the workpiece to be coated and inputting the contour information into a controller.

[0025] The above technical solution can avoid pre-inputting the contour information of the workpiece to be coated, making it convenient to use.

[0026] In one embodiment of the present invention, the measuring component includes: a measuring element that reciprocates along a linear direction; a measuring drive element that applies a force to the measuring element and keeps the measuring element in contact with the workpiece to be coated during one rotation of the workpiece; and a stroke detection element that is electrically connected to the controller, monitors the sliding stroke of the measuring element, and sends the stroke information to the controller.

[0027] With the above technical solution, if the contour information of the workpiece to be coated is unknown before the coating work is carried out, the measuring drive unit drives the measuring component to abut against the workpiece to be coated and records this position as the initial value. Then, the rotation drive unit drives the workpiece to be coated to rotate. During the rotation, the measuring drive unit drives the measuring component to abut against the workpiece to be coated. When the linear position of the measuring component changes, the stroke detection unit detects the sliding stroke of the measuring component and sends the stroke information to the controller. The controller combines the stroke information with the rotation angle of the workpiece to be coated to obtain the contour information of the workpiece to be coated. This adds another way to input the contour of the workpiece to be coated, making it more convenient to use.

[0028] In one embodiment of the present invention, the stroke detection element is configured as an encoder.

[0029] Through the above technical solution, the encoder detects the slippage information of the measuring component and sends the information to the controller.

[0030] In one embodiment of the present invention, the rotary drive device is configured as a servo motor with a speed reducer.

[0031] Through the above technical solution, the servo motor controls the workpiece to be coated to rotate in a fixed quantity, and the reducer reduces the speed of the servo motor.

[0032] As described above, the hot press laminating machine of the present invention has the following beneficial effects:

[0033] In use, the workpiece to be coated is installed on the support base. The controller controls the sliding drive device to drive the hot pressure roller to move and press the film strip supported by the material strip carrier assembly onto the workpiece to be coated. The external power supply device supplies power to the hot pressure roller. Then, the controller controls the rotation drive device to drive the workpiece to be coated to rotate. If the coating surface of the workpiece to be coated is not a regular arc shape when the workpiece is rotating, the distance from the contact position between the hot pressure roller and the workpiece to the rotation axis of the workpiece to be coated will change. At this time, the controller controls the sliding drive device to drive the hot pressure roller to slide according to the pre-input contour information of the workpiece to be coated, so that the hot pressure roller always presses the film strip and the workpiece to be coated. In this way, the workpiece to be coated can be coated on multiple surfaces parallel to the rotation axis of the workpiece in one installation and fixation, thereby improving the coating efficiency.

[0038] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features described herein can be combined with each other.

[0039] Please see Figure 1 This invention provides a hot press laminating machine, comprising:

[0040] The base 1 has a horizontal upper surface and a support frame 2 is fixed to the base 1 with screws. A bottom slide 3 is slidably mounted on the upper surface of the base 1 in the horizontal direction. The bottom slide 3 is driven to slide by a screw mechanism driven by a servo motor. A mounting plate 4 is fixed to the upper surface of the bottom slide 3 with screws.

[0041] It also includes controllers used to control the operation of the equipment.

[0042] Please see Figure 1 and Figure 2 It also includes a support base 5 for holding the workpiece to be coated and a rotary drive device 7 for driving the support base 5 to rotate. In this embodiment, the rotary drive device 7 is a servo motor with a reducer. The rotary drive device 7 is controlled by a controller and the controller records the output rotation angle. The housing of the reducer is fixed to the mounting plate 4 with screws. The output shaft of the reducer is fixed to the support base 5 with screws. The installation position of the workpiece to be coated is adjusted by adjusting the position of the bottom slide 3. The bottom slide 3 stops when coating. The axis of the reducer output shaft is set in the horizontal direction. The support base 5 is conformally set to the workpiece to be coated. The workpiece to be coated is sleeved on the support base 5. It also includes a stabilizing block 8 and a cylinder for driving the stabilizing block 8 to slide. The cylinder body is fixed to the mounting plate 4. The stabilizing block 8 is fixed to the piston rod of the cylinder through a coupling. The cylinder drives the stabilizing block 8 to press the end of the workpiece to be coated away from the reducer, thereby preventing the workpiece to be coated from falling off the support base 5 and improving the stability of the workpiece installation.

[0043] Please see Figure 1It also includes a sliding frame 9 that is slidably mounted on the support frame 2 in the vertical direction, a material belt bearing assembly 6 that is used to hold a film belt pre-coated with paint and drive the film belt to move in the direction of the film belt length, and a hot press roller 10 that is connected to an external power supply device and, after heating, squeezes the film belt toward the workpiece to be coated to transfer the paint onto the workpiece.

[0044] Please see Figure 1 It also includes a sliding drive device 11 that drives the sliding frame 9 to slide so that the hot pressure roller 10 mounted on the sliding frame 9 presses the workpiece to be coated. In this embodiment, the sliding drive device 11 is set as a lead screw mechanism driven by a servo motor. The lead screw is rotatably connected to the support frame 2. The lead screw sleeve is fixed to the sliding frame 9 by screws. The sliding drive device 11 is controlled by a controller.

[0045] Please see Figure 1 It also includes a heat insulation cover 12 that covers the periphery of the hot press roller 10 and has an open bottom. The hot press roller 10 is rotatably connected to the heat insulation cover 12 via a rotating shaft, and the axis of the rotating shaft is parallel to the axis of the reducer output shaft. The bottom of the hot press roller 10 extends out of the heat insulation cover 12 to contact the workpiece to be coated. The heat insulation cover 12 is slidably assembled with the sliding frame 9 via guide posts 13. An anti-detachment block is fixed at the top of the guide posts 13 to prevent the heat insulation cover 12 from detaching from the sliding frame 9. An elastic element is connected between 9. In this embodiment, the elastic element is set as a spring. The spring is sleeved on the guide post 13 and the two ends of the spring abut against the sliding frame 9 and the heat insulation cover 12 respectively. When the sliding drive device 11 drives the sliding frame 9 to slide in the direction of the workpiece to be coated, the elastic element deforms when the hot pressure roller 10 squeezes the workpiece to be coated, which plays a buffering role to prevent the workpiece to be coated from being deformed by pressure. At the same time, the pressure is transmitted to the workpiece to be coated through the elastic element, which can enhance the stability of the workpiece to be coated under pressure and improve the coating quality.

[0046] Knowing the contour information of the workpiece to be coated, the contour information is pre-input into the controller. The controller controls the rotary drive device 7 and the sliding drive device 11 to work. When the workpiece to be coated rotates and the distance between the coating position of the workpiece to be coated and the rotation axis of the support 5 changes, the controller controls the sliding drive device 11 to drive the hot pressure roller 10 to slide so that the hot pressure roller 10 always applies pressure to the workpiece to be coated.

[0047] Please see Figure 1 The tape carrying assembly 6 includes: a mounting rod 61 for carrying the film tape roll; a collection cylinder 62 for recycling the waste film tape after hot pressing; and a recycling drive for driving the collection cylinder 62 to rotate so that the waste film tape is wrapped around the collection cylinder 62.

[0048] The mounting rod 61 and the receiving cylinder 62 are both rotatably connected to the sliding frame 9, and the direction of the rotation axis is parallel to the direction of the rotation axis of the hot press roller 10. The recycling drive is set as a servo motor. The housing of the servo motor is fixed to the sliding frame 9 by screws, and the output shaft is coaxially fixed with the receiving cylinder 62. The end of the film tape is wound and fixed on the receiving cylinder 62.

[0049] Please see Figure 1 The tape carrying assembly 6 also includes at least two pressure rollers 63 arranged horizontally between the mounting rod 61 and the hot pressure roller 10. The pressure rollers 63 are rotatably connected to the sliding frame 9. In this embodiment, there are two pressure rollers 63, which are distributed vertically. After the film tape is drawn from the roll, it passes between the two pressure rollers 63 and finally winds onto the take-up cylinder 62. The pressure rollers 63 apply pressure to the film tape. When the take-up cylinder 62 is rotated by the recycling drive to wind the film tape onto the take-up cylinder 62, the force applied by the take-up cylinder 62 to the film tape needs to be greater than the frictional force of the pressure rollers 63 rotating to drive the film tape. The film tape between the take-up cylinder 62 and the pressure rollers 63 will be under tension, causing the film tape between the take-up cylinder 62 and the pressure rollers 63 to move along a specific route, thereby enhancing the stability of the equipment operation.

[0050] Please see Figure 1 The tape carrier assembly 6 also includes at least two conforming rollers 64. In this embodiment, two conforming rollers 64 are provided. Both conforming rollers 64 are rotatably connected to the sliding frame 9, and the two conforming rollers 64 are respectively arranged on both sides of the hot pressure roller 10. The bottom height of the conforming roller 64 is lower than the bottom height of the hot pressure roller 10. The film tape passes through the bottom of the conforming roller 64 and the hot pressure roller 10. When the hot pressure roller 10 squeezes the film tape to transfer the coating onto the workpiece to be coated, the conforming roller 64 squeezes the position of the film tape that is not in contact with the workpiece to the direction away from the pressure roller to enhance the adhesion between the film tape and the workpiece to be coated.

[0051] Please see Figure 1It also includes a measuring component 14 for measuring the contour of the workpiece to be coated and inputting the contour information into a controller. The measuring component 14 includes: a measuring element 141 that slides back and forth in a linear direction; a connecting frame 15 that is slidably mounted on the mounting plate 4 in a horizontal direction; in this embodiment, the measuring element 141 is a roller that is rotatably connected to the connecting frame 15; in other embodiments, ball bearings can also be used instead; a force is applied to the measuring element 141 so that the measuring element 141 rotates once during the workpiece to be coated. The shaping drive 142, which finally adheres to the workpiece to be coated, is configured as a cylinder in this embodiment. The shaping drive 142 drives the connecting frame 15 to slide, thereby driving the shaping component 141 to slide. When shaping the workpiece to be coated, air is supplied to the cylinder to make the shaping component 141 continuously move toward the position of the workpiece to be coated. When the shaping component 141 comes into contact with the workpiece to be coated, a small amount of air is continuously supplied to the cylinder to maintain the tendency of the cylinder to move and to enable the shaping component 141 to withstand the pressure of the workpiece to be coated. The reverse movement occurs as the rotating drive device 7 drives the workpiece to be coated to rotate one revolution, during which the measuring component 141 comes into contact with the workpiece to be coated. Additionally, the stroke detection component 143, which is electrically connected to the controller, monitors the sliding stroke of the measuring component 141 and sends the stroke information to the controller, is configured in this embodiment as an encoder with a roller mounted on it. The roller abuts against the mounting plate 4. During the sliding process, the roller rolls under the frictional force between the measuring component 141 and the mounting plate 4. The encoder detects the rotation angle information and sends it to the controller. The stroke information is obtained when the radius of the roller is known. The position where the measuring component 141 first abuts against the workpiece to be coated is recorded as the initial value. The contour of the workpiece to be coated can be obtained by combining the stroke information transmitted by the encoder, the angle information output by the rotating drive device 7, and the axial position of the reducer output shaft. When the contour of the workpiece to be coated is known, direct input to the controller is preferred; when the contour of the workpiece to be coated is unknown, it is measured by the measuring component 14.

[0052] In this invention, the workpiece to be coated is installed on the support base 5. The controller controls the sliding drive device 11 to drive the hot press roller 10 to move and press the film strip supported by the material strip carrier assembly 6 onto the workpiece to be coated. An external power supply device supplies power to the hot press roller 10. Then, the controller controls the rotation drive device 7 to drive the workpiece to be coated to rotate. If the coating surface of the workpiece to be coated is not a regular arc shape when the workpiece to be coated rotates, the distance from the contact position between the hot press roller 10 and the workpiece to be coated to the rotation axis of the workpiece to be coated will change. At this time, the controller controls the sliding drive device 11 to drive the hot press roller 10 to slide according to the pre-input contour information of the workpiece to be coated, so that the hot press roller always presses the film strip and the workpiece to be coated. In this way, the workpiece to be coated can be coated on multiple surfaces parallel to the rotation axis of the workpiece to be coated in one installation and fixation, thereby improving the coating efficiency.

[0053] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this invention should still be covered by the claims of this invention.
