TECHNICAL FIELD

[0001] The application belongs to the field of plastic plate processing, and more particularly to a plastic plate preparation device and process. BACKGROUND

[0002] Commonly used plastic plates have a PS (polystyrene plastic) melting point of about 166℃, and a processing temperature of generally 185-215℃. The thermal deformation temperature of PS is 70-80℃, the embrittlement temperature is -30℃, and the melting temperature is 240℃. PS is severely degraded at high vacuum and 330-380℃.

[0003] Foam is a material foamed from plastic particles, simply referred to as foam. Foam is divided into PU foam, anti-static foam, conductive foam, EPE, anti-static EPE, CR, EVA, bridged PE, SBR, EPDM, etc. Foam has a series of characteristics such as elasticity, light weight, fast pressure-sensitive fixing, easy to use, bending freely, ultra-thin volume, and reliable performance.

[0004] When the plastic plate is used, the foam is usually pasted on the plastic plate for use together. The common foam is adhered to the surface of the plastic plate by an adhesive such as glue. Due to the difference of the adhesive, the pasting effect is different. At the same time, some adhesives will pollute the environment. SUMMARY

[0008] The movement directions of the two adjusting plates are opposite. When the adjusting plates rotate relative to the adjusting screw, the adjusting plates move along the axial direction of the heating roller, thereby changing the effective heating length of the heating wires. A rotating roller for pasting the foam and the plastic plate together is rotatably connected to the support. A motor for driving the rotating roller to rotate is fixedly connected to the support.

[0009] As a further improvement of the present application, a plurality of heating extrusion rollers are slidably connected to the support side wall along the radial direction of the heating roller outside the periphery of the heating roller. A rotating disc coaxially arranged with the heating roller for driving each heating extrusion roller to move is rotatably connected to the outer wall of the support.

[0010] When the rotating disc moves to the reverse limit position, the heating extrusion roller is located at the limit position far away from the heating roller, and there is a gap between the heating extrusion roller and the heating roller.

[0011] When the rotating disc moves to the reverse limit position, the heating extrusion roller is located at the limit position far away from the heating roller, and there is a gap between the heating extrusion roller and the heating roller.

[0013] When the driving ring moves to the limit position far away from the heating roller, the synchronous rod moves to the limit position close to the axis of the heating roller, and the synchronous rod abuts against the adjusting plate, so that the adjusting plate rotates synchronously with the heating roller.

[0014] As a further improvement of the application, the heating extrusion roller is provided with a driving abutting rod at the end thereof, which can abut against the driving ring to drive the driving ring to move; one end of the driving abutting rod close to the driving ring is provided with a driving inclined surface.

[0015] A spring is installed between the driving ring and the end of the heating roller, which is used for driving the driving ring to move away from the heating roller.

[0016] When the rotating disc moves to the reverse limit position, the driving abutting rod is separated from the driving ring, and the driving ring is located at the limit position far away from the heating roller under the action of the spring.

[0017] As a further improvement of the application, the side wall of the support is provided with a foam seat used for placing foam; a positioning screw slidingly connected with the foam is slidingly connected to the side wall of the support close to the foam seat; the sliding direction of the positioning screw is parallel to the rotating shaft of the heating roller.

[0018] The positioning screw moves synchronously with the adjusting plate; when the positioning screw abuts against the foam, the gap between the two adjusting plates is equivalent to the width of the foam.

[0019] As a further improvement of the application, a threaded sleeve used for driving the positioning screw to rotate is rotationally connected to the side wall of the support; an arc-shaped sliding groove coaxial with the threaded sleeve is arranged on the side wall of the support close to the heating roller; a sliding gear slidingly connected with the heating roller is slidingly connected in the arc-shaped sliding groove; the sliding gear and the threaded sleeve are drivingly connected through a transmission belt.

[0020] The side wall of the rotating disc is provided with a driving wall abutting against the outer wall of the sliding gear to drive the sliding gear to move; the end of the heating roller is provided with a heating roller gear capable of meshing and driving the sliding gear.

[0021] When the rotating disc moves to the reverse limit position, the sliding gear meshes with the heating roller gear.

[0022] As a further improvement of the application, a laminating roller for extruding the foam and the plastic plate is longitudinally slidingly connected above the rotating roller on the support; a push rod for driving the longitudinal sliding of the laminating roller is fixedly connected to the side wall of the support; a rack for driving the rotation of the rotating disc is arranged at the end of the laminating roller.

[0023] When the push rod moves the laminating roller to the limit position away from the rotating roller, the rack drives the rotating disc to move to the reverse limit position.

[0024] The push rod is an electric push rod or a pneumatic push rod; and the motor is a stepping motor.

[0025] As a further improvement of the application, a reciprocating screw parallel to the rotating shaft of the heating roller is rotatably connected above the heating roller on the support; a cleaning seat in transmission connection with the reciprocating screw is arranged on the reciprocating screw; a cleaning knife capable of abutting against the outer wall of the heating roller is arranged at one end of the cleaning seat; a collecting groove for collecting garbage is arranged on the cleaning seat close to the cleaning knife; and the heating roller, the reciprocating screw and the rotating roller are in transmission connection through a synchronous belt.

[0030] S3: The heating roller heats the surface of the plastic plate to melt the surface of the plastic plate.

[0031] S4: The rotating roller and the laminating roller extrude and laminate the plastic plate and the foam.

[0032] Compared with the prior art, the beneficial effects of the present application are that the scheme utilizes the viscosity of the melted plastic plate itself to make the foam and the plastic plate laminated together, without the need for additional adhesive, thereby reducing waste and saving costs.

[0033] The scheme can adapt to plastic plates of different widths by controlling the movement of the adjusting plate and changing the heating range of the heating wire on the heating roller, that is, the heating range of the heating roller is always equal to the width of the plastic plate, so that the waste of heat caused by the heating range of the heating roller being greater than the width of the plastic plate when heating plastic plates of different widths, or the heating range of the heating roller being less than the width of the plastic plate and the plastic plate being unable to be completely melted, thereby affecting the subsequent operation, is avoided.

[0034] The scheme can heat the plastic plate and drive the adjusting plate to rotate by controlling the movement of the synchronous rod, so as to change the heating range of the heating wire.

Embodiment

[0045] Specific embodiment one: please see Figures 1-8 A plastic plate preparation device, comprising a support 1, a rotating connection on the support for heating the plastic plate 102 heating roller 2; the rotating shaft of the heating roller is arranged along the left and right directions; the side wall of the support is provided with a heating roller connecting hole connected with the heating roller; the heating roller is provided with an adjusting mechanism.

[0046] The adjusting mechanism comprises an adjusting screw 31 coaxially arranged with the heating roller and fixedly connected to the support, two adjusting plates 33 threadedly connected with the adjusting screw and slidingly connected to the heating roller along the axial direction of the heating roller, and a heating wire 32 arranged in a spiral line and mounted between the two adjusting plates.

[0047] The movement directions of the two adjusting plates are opposite; when the adjusting plates rotate relative to the adjusting screw, the adjusting plates move along the axial direction of the heating roller, thereby changing the effective heating length of the heating wire; the support is rotatably connected with a rotating roller 72 for laminating the foam and the plastic plate together; the support is fixedly connected with a motor 71 for driving the rotating roller to rotate.

[0048] The adjusting screw is fixedly connected with a screw positioning frame 311 fixedly connected with the side wall of the support; the heating wire is fixedly connected to the adjusting plate; since the heating wire is arranged in a spiral line, when the spacing between the two adjusting plates changes, the pitch of the heating wire also changes; the effective heating length of the heating wire is the spacing between the two adjusting plates.

[0049] When the heating wire works, the heat generated by the heating wire is directly transmitted to the heating roller, and the part of the heating roller sidewall directly opposite to the heating wire has the highest temperature, which heats the plastic plate and melts the end of the plastic plate in contact with the heating roller, so as to facilitate the adhesion of the plastic plate and the foam.

[0050] The scheme utilizes the viscosity of the melted plastic plate to make the foam adhere to the plastic plate, without the need for additional adhesive, thereby reducing waste and saving costs.

[0051] The scheme can adapt to plastic plates of different widths by controlling the movement of the adjusting plate and changing the heating range of the heating wire on the heating roller, that is, the heating range of the heating roller is always equal to the width of the plastic plate, thereby avoiding the waste of heat due to the heating range of the heating roller being greater than the width of the plastic plate when heating plastic plates of different widths, or the plastic plate not being completely melted due to the heating range of the heating roller being less than the width of the plastic plate, thereby affecting subsequent operations.

[0052] The adjusting screw sidewall is provided with two threads 312; one thread is in driving connection with one adjusting plate; and the rotation directions of the two threads are opposite. The adjusting plate is provided with a threaded connector in sliding connection with the threads.

[0053] The support sidewall is slidingly connected with a plurality of heating extrusion rollers 41 in the radial direction of the heating roller along the outer periphery of the heating roller; and the support outer wall is rotatably connected with a rotating disc 42 coaxially arranged with the heating roller and used for driving the movement of each heating extrusion roller.

[0054] When the rotating disc moves forward, the heating extrusion roller can extrude the plastic plate onto the heating roller, so that the plastic plate is more closely attached to the heating roller, which is conducive to the melting of the plastic plate by the heating roller.

[0055] When the rotating disc moves to the reverse limit position, the heating extrusion roller is located at the limit position away from the heating roller, and there is a gap between the heating extrusion roller and the heating roller, so that the plastic plate can freely pass between the heating extrusion roller and the heating roller, thereby facilitating the installation of the plastic plate.

[0056] The support sidewall is provided with a plurality of radial sliding grooves 11 arranged in the radial direction of the heating roller; the heating extrusion roller is provided with extrusion roller sliding columns 412 at the centers of both ends in sliding connection with the radial sliding grooves; and one end of the rotating disc is provided with a plurality of adjusting inclined grooves 421 in sliding connection with the extrusion roller sliding columns.

[0057] When the rotating disc rotates, the adjusting inclined groove forces the extrusion roller sliding column to move along the radial sliding groove, and the heating extrusion roller moves in the radial direction of the heating roller.

[0058] The adjusting mechanism further comprises a synchronous rod 36 slidably connected in the heating roller along the radial direction of the heating roller, and a driving ring 34 slidably connected to one side of the heating roller along the axial direction of the heating roller and used for driving the synchronous rod to slide; the driving ring is coaxially arranged with the heating roller.

[0059] When the driving ring moves to the limit position away from the heating roller, the synchronous rod moves to the limit position close to the axis of the heating roller, and the synchronous rod abuts against the adjusting plate, at which time the adjusting plate rotates synchronously with the heating roller.

[0060] The outer wall of the adjusting plate is uniformly provided with synchronous clamping grooves capable of clamping the synchronous rod; when the synchronous rod moves to the limit position close to the axis of the heating roller, the synchronous rod enters one of the synchronous clamping grooves and generates a friction force between the synchronous rod and the adjusting plate, thereby driving the adjusting plate to rotate and forcing the adjusting plate to move axially along the adjusting screw, and the synchronous clamping groove also moves on the synchronous rod, thereby enabling the adjusting plate to rotate synchronously with the synchronous rod in the circumferential direction and axially relatively slide.

[0061] The scheme enables the heating roller to heat the plastic plate and drive the adjusting plate to rotate by controlling the movement of the synchronous rod, thereby changing the heating range of the heating wire.

[0062] The side wall of the driving ring is provided with a driving connecting plate 341; the driving connecting plate is provided with driving inclined grooves 342 obliquely distributed thereon; the synchronous rod is provided with a synchronous sliding column 361 slidably connected with the driving inclined grooves; and the driving inclined grooves are located in the plane where the radius of the driving ring is located.

[0063] The heating roller is provided with heating connecting shafts 21 centrally arranged at both ends thereof; and the driving ring is sleeved on the heating connecting shafts.

[0064] The end of the heating extrusion roller is provided with a driving abutting rod 411 capable of abutting against the driving ring and thereby driving the driving ring to move; one end of the driving abutting rod close to the driving ring is provided with a driving inclined surface; and the outer wall of the heating extrusion roller is rotationally connected with a rotating tube in contact with the plastic plate.

[0065] The driving ring and the end of the heating roller are mounted with a spring 35 used for driving the driving ring to move away from the heating roller.

[0066] When the rotating disc moves to the reverse limit position, the driving abutting rod is separated from the driving ring, and the driving ring is located at the limit position away from the heating roller under the action of the spring.

[0067] When the rotating disc is positively rotated by a certain angle, the driving inclined surface contacts the driving ring and forces the driving ring to move to the limit position close to the heating roller, the spring is contracted, the synchronous sliding column 361 is separated from the adjusting plate, and the heating roller does not drive the adjusting plate to rotate, at which time the rotating disc continues to be positively rotated and the driving ring does not move.

[0068] The heating extrusion roller in the scheme can extrude the plastic plate to the heating roller, so that the plastic plate is closely attached to the heating roller, and the driving ring can be controlled to move, so that the heating roller drives the heating wire to move.

[0069] The support side wall is provided with a foam seat 13 for placing foam; the foam rotates on the foam seat; the position close to the foam seat of the support side wall is slidingly connected with a positioning screw 54 capable of abutting against the foam; the sliding direction of the positioning screw is parallel to the rotating shaft of the heating roller.

[0070] The positioning screw moves synchronously with the adjusting plate; when the positioning screw abuts against the foam, the distance between the two adjusting plates is equivalent to the width of the foam.

[0071] The support side wall is rotatably connected with a threaded sleeve 53 for driving the positioning screw to rotate; the threaded sleeve is provided with internal threads in transmission connection with the positioning screw; the support side wall is provided with a sliding opening 14 with a non-circular cross section; the positioning screw is slidingly connected in the sliding opening, so that the positioning screw only moves axially and does not rotate; the position close to the heating roller of the support side wall is provided with an arc-shaped sliding groove 12 coaxial with the threaded sleeve; the arc-shaped sliding groove is slidingly connected with a sliding gear 51 capable of being in transmission connection with the heating roller; the sliding gear and the threaded sleeve are in transmission connection through a transmission belt 52.

[0072] The rotating disc side wall is provided with a driving wall 422 abutting against the outer wall of the sliding gear to drive the sliding gear to move; the end of the heating roller is provided with a heating roller gear 22 capable of being in meshing transmission with the sliding gear; the heating roller gear is coaxially arranged at the end of the heating connection shaft away from the center of the heating roller.

[0073] When the rotating disc moves to the reverse limit position, the sliding gear is in meshing transmission with the heating roller gear.

[0074] When the rotating disc rotates forward by a certain angle from the reverse limit position, the driving wall pushes the sliding gear to move along the arc-shaped sliding groove, so that the sliding gear is no longer in meshing transmission with the heating roller gear.

[0075] The threads on the positioning screw and the adjusting screw are the same, and the diameters of the threaded sleeve, the sliding gear and the heating roller gear are the same, so that the distances moved by the positioning screw and the adjusting plate per unit time are equal.

[0076] The scheme synchronously moves the positioning screw and the adjusting plate, so that the two adjusting plates are driven to move to a position equivalent to the width of the foam, without the need for manual distance measurement, saving time and effort.

[0077] The rotating disc in the scheme can drive the movement of each heating extrusion roller and drive the movement of the sliding gear, so as to conveniently control the movement of the positioning screw.

[0078] The support is longitudinally and slidingly connected with a laminating roller 62 above the rotating roller for extruding the foam and the plastic plate; the rotating shafts of the laminating roller and the rotating roller are parallel to the heating roller; the side wall of the support is fixedly connected with a push rod 61 for driving the laminating roller to longitudinally slide; the end of the laminating roller is provided with a rack 621 for driving the rotating disc to rotate; the outer wall of the rotating disc is coaxially provided with a rotating disc gear 423 engaged with the rack.

[0079] When the push rod drives the laminating roller to move to the limit position away from the rotating roller, the rack drives the rotating disc to move to the reverse limit position.

[0080] The push rod is an electric push rod or a pneumatic push rod; and the motor is a stepping motor.

[0081] The laminating roller can be cooperated with the rotating roller to clamp the extruded foam and the plastic plate, so that the laminating of the extruded foam and the plastic plate is facilitated, and the rotating disc can be driven to rotate without an additional power source.

[0082] The support is rotatably connected with a reciprocating screw 81 parallel to the rotating shaft of the heating roller above the heating roller; the reciprocating screw is provided with a cleaning seat 82 in driving connection with the reciprocating screw; one end of the cleaning seat is provided with a cleaning knife 821 capable of abutting against the outer wall of the heating roller; the cleaning seat is provided with a collecting groove 822 for collecting garbage near the cleaning knife; the heating roller, the reciprocating screw and the rotating roller are drivingly connected through a synchronous belt.

[0083] When the reciprocating screw rotates in one direction, the cleaning seat reciprocates along the axial direction of the reciprocating screw and scrapes off the residual plastic plate attached to the surface of the heating roller through the cleaning knife, so as to avoid affecting the heating of the subsequent plastic plate by the heating roller.

[0084] One end of the cleaning seat away from the cleaning knife is provided with a cleaning sliding plate 823; the cleaning sliding plate is provided with a cleaning driving groove arranged along the radius direction of the reciprocating screw; the support is slidingly connected with a cleaning sliding rod 83 in sliding connection with the cleaning driving groove and driving the cleaning seat to rotate; the cleaning sliding rod is provided with a cleaning handle 831.

[0085] The side wall of the support is provided with a sliding rod sliding groove in sliding connection with the cleaning sliding rod and arranged along the horizontal direction; by moving the cleaning handle, the cleaning seat is rotated relative to the reciprocating screw, so as to control the cleaning knife to be close to or away from the heating roller, thereby facilitating the cleaning of the surface of the heating roller by the cleaning knife.

[0086] In the initial state, the push rod 61 drives the matching roller 62 to the extreme position away from the rotating roller, the rotating disc 42 is located at the reverse extreme position, the drive ring moves to the extreme position away from the heating roller, the synchronous rod moves to the extreme position close to the heating roller axis, and the two adjusting plates 33 are located at the extreme position away from each other.

[0087] In use, the foam with the same width as the plastic plate is first installed on the support and passes between the rotating roller 72 and the matching roller, and then the plastic plate passes between the heating roller 2 and the heating extrusion roller 41, and also passes between the rotating roller and the matching roller.

[0088] Then the operator presses the corresponding button, the motor 71 works, and the rotating roller 72 drives the heating roller to rotate. Since the synchronous rod 36 and the two adjusting plates are in close contact at this time, the rotating roller drives the two adjusting plates to rotate synchronously in the circumferential direction, and the adjusting plates move axially along the adjusting screw rod. At the same time, the rotation of the heating roller drives the sliding gear 51 to rotate, and then the positioning screw rod is driven to move synchronously through the threaded sleeve 53. The two adjusting plates move closer to each other, and the positioning screw rod moves in the direction of the foam.

[0089] When the positioning screw rod moves to contact the foam, the operator presses the corresponding button, and the motor stops working. At this time, the distance between the two adjusting plates is equivalent to the width of the foam, and the heating range of the heating wire is equivalent to the width of the foam.

[0090] Then the operator presses the corresponding button, the push rod drives the matching roller 62 to move towards the rotating roller, until the matching roller and the rotating roller clamp the foam and the plastic plate; at the same time, the rack on the matching roller drives the rotating disc gear 423 to rotate, and then the rotating disc rotates forward by a certain angle.

[0091] During the process of rotating the rotating disc forward by a certain angle, the driving wall 422 on the rotating disc pushes the sliding gear 51 to move, so that the sliding gear is separated from the heating roller gear 22. At the same time, the rotating disc drives each heating extrusion roller to move towards the heating roller through the adjusting inclined groove 421, and finally the heating extrusion roller extrudes the plastic plate to the outer wall of the heating roller. At the same time, the driving abutment rod 411 abuts against the drive ring, forcing the drive ring to move to the position close to the heating roller, and the synchronous rod is separated from the adjusting plate 33 through the driving inclined groove 342. At this time, the heating roller no longer drives the adjusting plate to rotate.

[0092] Then the operator presses the corresponding button, and the heating wire works to heat the heating roller, and then the heating roller melts the end of the plastic plate in contact with the heating roller. At the same time, the motor works to drive the rotating roller to rotate, and the rotating roller and the matching roller extrude the plastic plate and the foam, and drive the plastic plate that has been matched to move away from the heating roller, and then the plastic plate that has just been melted by the heating roller moves towards the rotating roller. The motor continues to work, and then the foam is continuously attached to the plastic plate.

[0093] In the above process, as the heating roller continues to melt the plastic plate, a part of the plastic plate will inevitably adhere to the surface of the heating roller, which will affect the melting of the subsequent plastic plate by the heating roller. Therefore, when the operator observes that the heating roller needs to be cleaned, the cleaning handle is manually slid to move the cleaning knife towards the heating roller in the direction of 821 until it abuts tightly against the outer wall of the heating roller, and at the same time, the rotating roller drives the reciprocating screw 81 to continuously rotate in one direction, and then the reciprocating screw continuously drives the cleaning knife to reciprocate on the outer wall of the heating roller, and the residues on the heating roller will be collected into the collecting groove under the action of the cleaning knife. After a certain period of time, the operator reversely moves the cleaning handle to separate the cleaning knife from the heating roller, and then the cleaning of the heating roller is completed.

[0094] When the device is working, the operator presses the corresponding button, the motor and the heating wire stop working, the push rod drives the laminating roller to move to the limit position away from the rotating roller, at the same time, the rack drives the rotating disc to move to the reverse limit position, the sliding gear 51 is engaged with the heating roller gear 22 again, the heating extrusion roller 41 moves to the limit position away from the heating roller, the driving abut rod 411 is separated from the driving ring 34, and the synchronous rod is again abutted with the adjusting plate; then the motor works reversely, the heating roller rotates reversely, and then the two adjusting plates move away from each other, after a certain period of time, the operator presses the corresponding button, the motor stops working, and the device returns to the initial state for the next use.
