Description

TECHNICAL FIELD

[0001] The present application relates to the conveying technical field, especially to a continuous conveying system for a color steel plate hot press. BACKGROUND

[0002] The color steel rock wool sandwich panel takes natural minerals such as basalt as raw materials, and is formed into a high-performance fireproof panel material after being melted into fibers at high temperature and being solidified and formed with a bonding agent.

[0003] Its core production process relies on the continuous conveying system of the double-track laminating machine; the plate after assembly enters the laminating station at a uniform speed through the closed-loop track conveyor, and under the synchronous transmission of the PLC control, the upper and lower tracks are driven to rotate in reverse by the servo motor, realizing the precise conveying and dynamic pressing of the plate. In this process, the heating system controls the temperature of the track plate through the circulating air duct, promotes the synchronous solidification of the bonding agent during conveying, and forms a structural integrated composite panel.

[0004] However, during the continuous conveying process, the material plate may deviate, affecting the processing precision and efficiency, and the bonding agent is easy to adhere to the surface of the track, forming a glue residue. In the traditional conveying machine in the hot pressing of viscous materials, the accumulation of the glue residue on the surface of the track leads to an increase in the slip rate and a decrease in the conveying efficiency. Although the traditional glue scraping mechanism is arranged at the discharge end of the track, it only scrapes the glue by a scraper, lacks integrated collection, and the scraped glue is directly retained around the conveying line and re-adhered to the surface of the track with the track, causing surface contamination and quality defects of the plate. Therefore, frequent shutdown is required for cleaning, which eventually interrupts the continuous production.

[0005] In view of the above technical problems, the present application discloses a continuous conveying system for a color steel plate hot press. SUMMARY

[0006] The present application aims to overcome the shortcomings of the prior art, and provides a continuous conveying system for a color steel plate hot press, to solve the technical problem that in the continuous production line of the color steel rock wool sandwich panel, the bonding agent overflows and adheres to the surface of the track during the conveying process of the track laminating machine, forming a glue residue, which leads to the track pollution and shutdown of the continuous conveyor due to the residue of viscous materials. The present application has the advantage of ensuring the continuity of the production of the color steel rock wool sandwich panel in the continuous production line of the color steel rock wool sandwich panel through the glue scraping mechanism.

[0007] The present application is realized by the following technical scheme: the present application discloses a continuous conveying system for a color steel plate hot press, comprising a conveying assembly, a lifting lead screw mechanism, a circulating mechanism, a temperature control assembly, a glue scraping mechanism and a side chain mechanism, the conveying assembly comprises a closed-loop conveying channel composed of symmetrically arranged lower conveying tracks and upper conveying tracks;

[0008] The lifting screw mechanism is used to drive the synchronous vertical displacement of the upper conveying track, dynamically adapt the material thickness, the temperature control assembly is integrated in the middle section of the conveying channel, cooperates with the circulating mechanism to control and solidify the material, the side chain mechanism is symmetrically arranged on both sides of the feeding end for initial positioning of the material, and the shoveling mechanism includes a cleaning assembly and a collecting assembly.

[0009] Further, the cleaning assembly includes a shell fixed to the lifting screw mechanism, a horizontal plate is arranged inside the shell, an arc-shaped positioning groove is formed in the horizontal plate, a sliding rod is slidingly inserted into the positioning groove, a scraper is connected to the bottom end of the sliding rod, and the top end of the scraper is connected to a spring through a round rod to elastically press against the surface of the track; a spiral groove is arranged on the outer wall of the round rod, a sliding block in the groove is fixed to the horizontal plate; the collecting assembly is linked to the sliding rod through a connecting piece to convert the swinging of the scraper into the horizontal reciprocating motion of the collecting assembly, the spring continuously applies pressure to the scraper to ensure that the bottom end of the scraper is always in close contact with the surface of the track, and the unevenness of the track or the thickness change of the glue is self-adapted to ensure that there is no dead angle in the glue scraping.

[0010] Further, the lifting screw mechanism includes symmetrically distributed lifting screw part one, lifting screw part two and lifting drive motor, which are connected to the lower conveying track and the upper conveying track through positioning plate one and positioning plate two, the lifting drive motor drives the lifting screw part one through a bevel gear and drives the lifting screw part two through a thread linkage to realize the synchronous pressing of the upper conveying track; wherein the inner surfaces of the upper conveying track and the lower conveying track are uniformly provided with protrusions. The lifting screw mechanism realizes the synchronous pressing of the upper conveying track in a compact space through the rigidity cooperation of the bevel gear transmission and the thread linkage double-stage screw, has the functions of mechanical self-locking, low maintenance and dynamic stroke adaptation, and solves the problems of thickness fluctuation and pressure instability in the lamination process.

[0011] Further, the inner sides of the two lower conveying tracks and the two upper conveying tracks are symmetrically connected with telescopic tensioning devices, and the lower conveying tracks and the upper conveying tracks are connected with track drive motors.

[0012] Further, the temperature control assembly includes an electric heating device and a gas heating device, and the bottom ends of the two lower conveying tracks are respectively provided with circulating air ducts, and the circulating mechanism includes a circulating fan installed at the temperature control assembly.

[0013] Further, the side tracks of the side chain mechanism are fixed to the positioning plate one through supports, when the lifting drive motor drives the upper conveying track to lift, the bottom ends of the side tracks are flush with the top ends of the lower conveying tracks, and the side tracks cooperate with the upper conveying tracks and the lower conveying tracks to form a dynamic guide channel, so that the material is always constrained by both sides during the conveying process to inhibit lateral deviation and torsion.

[0014] Further, the number of turns of the spiral groove is less than 1 / 4 turn.

[0015] Furthermore, the spiral groove is configured such that when the scraper is vertically displaced by the resistance of the track, the slide rod slides along the positioning groove trajectory, forcing the slider in the spiral groove to drive the round rod to rotate by an angle α, thereby realizing the adjustment of the scraper cutting angle.

[0016] Furthermore, the collection assembly includes two collection components symmetrically installed on the lower sides of the housing. Each of the two collection components has a vertically inserted rod at its outer end. Each of the two rods has a connecting plate fixedly connected to its top end. The two connecting plates are bent, and the other ends of the two connecting plates are rotatably connected to the outer wall of the adjacent sliding rod.

[0017] Furthermore, both of the collecting components are fixedly connected to a protrusion parallel to the extension direction of the second positioning plate. The two positioning plates below the protrusions are respectively provided with sliding grooves. The sliding grooves are slidably connected to the protrusions, so that when the sliding rod slides along the scraper and swings, it will push the entire collecting component to slide back and forth.

[0018] Furthermore, a connecting rod is vertically slidably connected to the middle of the horizontal plate. The connecting rod is "I" shaped, and its upper and lower horizontal ends are movable at the upper and lower ends of the horizontal plate, respectively. The two horizontal ends of the connecting rod located below the horizontal plate are rotatably connected to abutment wheels, and the tops of the two abutment wheels abut against the inner protrusion of the matching upper conveyor belt.

[0019] The present invention has the following advantages:

[0020] (1) The present invention adopts the connection between the side chain mechanism and the lifting screw mechanism. By directly fixing the brackets of the symmetrically arranged side tracks to the positioning plate of the lifting screw mechanism, the dynamic constraint and pressing action during the conveying process of the plate are coordinated. When the lifting drive motor drives the lifting screw component one and the lifting screw component two to press down on the upper conveyor track at the same time, the side tracks of the side chain mechanism apply a rigid limiting force to the plate from both sides of the feeding end, suppressing the lateral displacement tendency of the plate in the track transmission. Through the coordination of the glue scraping mechanism and dynamic lifting, the downtime for cleaning the conveyor belt is reduced, and the continuity of conveying is improved.

[0021] (2) This invention adopts a mechanical linkage integrated design for scraping and collecting adhesive. The scraper and the spiral groove work together to drive the collecting component to move synchronously, thus solving the problem of secondary pollution caused by adhesive residue. The scraper elastically presses against the surface of the track at a preset angle. When the resistance triggers the vertical displacement of the scraper, it drives the spiral groove on the outer wall of the round rod to convert the vertical movement into an α-angle rotational swing. This enhances the scraper's ability to peel off viscous adhesive. At the same time, the outer slide rod drives the collecting component. The swing of the scraper pushes the insert rod through the bent connecting plate, driving the collecting component to move horizontally back and forth along the slide groove of the second positioning plate. The tilted scraper directly guides the peeled adhesive into the collecting component that is moving horizontally and uniformly, avoiding adhesive dripping and contaminating the conveying channel.

[0022] (3) The side chain mechanism of the present invention is rigidly connected to the positioning plate of the lifting screw mechanism through the bracket. When the lifting screw mechanism adjusts the height of the upper conveyor track to adapt to materials of different thicknesses, the side track can effectively guide the material to enter and apply a double radial constraint force before the material enters the lamination zone to counteract the lateral offset trend caused by adhesive rheology or uneven pressure in the track transmission and improve the lamination alignment accuracy.

[0035] Embodiments, reference Figures 1-10 :

[0036] A continuous conveying system for a color steel plate hot press is disclosed. The embodiment takes a closed-loop conveying system as the core and is composed of a conveying assembly (including a lower conveying track 1 and an upper conveying track 11), a lifting lead screw mechanism, a circulating mechanism, a temperature control assembly 2, etc. After the material enters from the inlet, the track is synchronously driven (the speed is automatically matched with the production line) under the control of the PLC, and the glue heating and curing is completed synchronously during the conveying process. The lower conveying track 1 and the upper conveying track 11 are designed to rotate in opposite directions, and the track spacing is dynamically adjusted by the lifting lead screw mechanism to adapt to the continuous conveying and pressing requirements of materials of different thicknesses.

[0037] Specifically (see Figure 2 the product conveying direction), the product enters from the inlet and runs at a constant speed to the outlet side, and the speed is automatically matched with the production line under the control of the PLC, and the glue heating and curing is completed within a specified time; during the operation of the upper and lower tracks, a set of glue scraping mechanism is arranged on the upper and lower tracks respectively to automatically clean the glue remaining on the surface of the track plate, avoid the secondary pollution of the glue to the conveying belt and the material, and ensure the stable operation of the conveying system and the output quality.

[0038] The conveying assembly is composed of a lower conveying track 1 and an upper conveying track 11 arranged symmetrically to form a closed-loop continuous conveying channel. The upper conveying track 11 realizes synchronous vertical displacement through a lifting adjustment mechanism to dynamically adapt to the conveying gap of materials of different thicknesses. The temperature control assembly 2 is integrated in the middle section of the conveying system and cooperates with the circulating mechanism to control the temperature of the material being conveyed, ensuring that the glue curing is completed synchronously during the conveying process.

[0039] The side chain mechanism is symmetrically arranged at the inlet end (product inlet direction) for initial positioning of material conveying to avoid deviation; the glue scraping mechanism is integrated on the upper and lower sides at the outlet end (product outlet direction) to remove the residual glue on the surface of the track in real time through the elastic contact type scraping component, ensuring the continuity of conveying and the output quality.

[0040] Specifically, reference can be made to Figure 2 , Figure 3 andFigure 4 Wherein the upper and lower tracks in the conveying assembly are respectively driven by AC servo motors, the upper track rotates counterclockwise and the lower track rotates clockwise (the rotation directions of the upper and lower tracks can be referred to Figure 3 the angle of view), and the upper and lower tracks are synchronously started and stopped.

[0041] Wherein each scraping mechanism is composed of a cleaning assembly and a collecting assembly, the cleaning assembly includes a shell 4, the upper and lower ends of the shell 4 are respectively connected with the upper and lower ends of the lifting lead screw mechanism, a horizontal plate 41 is fixedly connected inside the shell 4, arc-shaped positioning grooves 42 are symmetrically formed on both sides of the matching positions of the lower conveying track 1 and the upper conveying track 11 inside the horizontal plate 41, the positioning grooves 42 penetrate through the upper and lower end faces of the horizontal plate 41, sliding rods 46 are respectively slidably inserted into the two positioning grooves 42, scraper plates 45 are fixedly connected to the bottom ends of the two sliding rods 46, the bottom ends of the two scraper plates 45 are in inclined abutment with the surfaces of the lower conveying track 1 and the upper conveying track 11, round rods 44 are fixedly connected to the top ends of the two scraper plates 45, the two round rods 44 are movably inserted into the horizontal plate 41, the outer walls of the two round rods 44 are slidably connected with the horizontal plate 41, springs 43 are fixedly connected to the top ends of the two round rods 44, the other ends of the two springs 43 are connected with the inner wall of the shell 4, helical grooves 47 are formed in the outer walls of the two round rods 44, sliding blocks are slidably connected in the two helical grooves 47, the two sliding blocks are connected with the horizontal plate 41, the two sliding rods 46 located on the outer sides are connected with the collecting assembly, and are used for synchronously reciprocating and rotating when the scraper plates 45 vertically slide at the positions abutting against the lower conveying track 1 and the upper conveying track 11, and driving the entire collecting assembly to move.

[0042] Referring to Figure 5 , Figure 6 and Figure 8 , during the operation of the equipment, the bottom ends of the two scraper plates 45 are in inclined abutment with the track plate surfaces, and due to the inclined state, the scraped and cleaned glue can be better guided into the collecting assembly; the sliding connection of the positioning grooves 42 and the sliding rods 46 can further ensure the stability of the scraper plates 45 during the rotation adjustment; the number of turns of the helical grooves 47 is less than 1 / 4 turn.

[0043] The short radian of the helical groove 47 is limited within one-fourth of the circumference. When the running resistance of the track triggers the vertical displacement of the scraper plate 45, the sliding rod 46 slides along the track of the positioning groove 42, forcing the sliding block in the helical groove 47 to move relatively. This limited helical motion converts the vertical displacement into a preset rotation angle, driving the scraper plate 45 to produce a small but continuous α angle swing. The change in the rotation angle continuously fine-tunes the cutting direction of the scraper plate 45 blade, improving the stripping efficiency of different viscosity glues.

[0044] Referring to Figure 10A connecting rod 6 is vertically slidably connected to the middle of the horizontal plate 41. The connecting rod 6 is "I"-shaped, and its upper and lower horizontal ends are movable at the upper and lower ends of the horizontal plate 41, respectively. Abutment wheels 61 are rotatably connected to both sides of the horizontal end of the connecting rod 6 located below the horizontal plate 41. The tops of the two abutment wheels 61 abut against the inner protrusions of the matching upper conveyor belt 11. The upper and lower ends of the connecting rod 6 are connected to 44 and the abutment wheels 61, respectively. When the upper conveyor belt 11 is in operation, it can provide downward pressure to the entire connecting rod 6 and simultaneously drive the entire connecting rod 6 and scraper 45 to descend. The spring 43 returns the rod to its original position at the non-protruding connection point on the inner side of the abutment wheel 61 and the upper conveyor belt 11.

[0045] The lifting screw mechanism includes several lifting screw components 13 evenly and symmetrically installed at the bottom ends of both sides of the two lower conveyor tracks 1. Each lifting screw component 13 is fixedly connected to a positioning plate 16. Each positioning plate 16 is connected to the adjacent lower conveyor track 1. The top of each lifting screw component 13 is connected to a lifting screw component 2 14. Each lifting screw component 2 14 is fixedly connected to a positioning plate 2 17. Each positioning plate 2 17 is connected to the adjacent upper conveyor track 11. A lifting drive motor 15 is connected in the middle of the multiple lifting screw components 13 in one direction to synchronously drive the multiple lifting screw components 13 and realize the synchronous downward pressing of the two lower conveyor tracks 1. The inner surfaces of the upper conveyor track 11 and the lower conveyor track 1 are evenly provided with protrusions.

[0046] The lifting screw component 13 and the lifting drive motor 15 are driven by bevel gears, and the lifting screw component 13 and the lifting screw component 2 14 are connected by threads.

[0047] For details, please refer to Figure 1 and Figure 4 The upper track is driven by a servo motor lifting drive motor 15, which controls the rotation of the lifting screw to lift the upper track, depending on the thickness of the product. The lifting screw component 13 and the lifting screw component 14 can also be rigidly connected through a coupling for synchronous drive, and the lifting accuracy error is controlled within 0.15mm.

[0048] The inner sides of the two lower conveyor tracks 1 and the two upper conveyor tracks 11 are symmetrically connected with telescopic tensioning devices 12, and both the lower conveyor tracks 1 and the upper conveyor tracks 11 are connected with track drive motors.

[0049] For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 It is used to synchronously drive the two lower conveyor belts 1 and the two upper conveyor belts 11 to ensure that the material is conveyed while being pressurized synchronously.

[0050] The temperature control assembly 2 comprises an electric heating device and a gas heating device, and circulating air ducts 21 are respectively arranged at the bottom ends of the two lower conveying caterpillar belts 1.

[0051] Specifically, the device is equipped with two sets of parallel heating systems, and the gas heating system and the electric heating system can operate simultaneously or individually, and the control mode can be selected from various modes such as servo automatic control and manual control. An intelligent algorithm is adopted to automatically analyze and select the heating energy type by collecting energy consumption data and energy prices. Hot air enters the air duct from the inlet side under the action of the recirculating fan in the combustion chamber, contacts the caterpillar plate to heat it, and then returns to the combustion chamber from the outlet side after heat exchange to be heated again. Two temperature sensors are arranged on the upper and lower conveying caterpillar belts respectively to detect the temperature of the caterpillar belt. When the temperature difference exceeds the program setting value, the control system sends a temperature control instruction to the heating system to adjust the heating temperature, thereby realizing temperature control of the caterpillar plate.

[0052] Further, part of the air ducts are made of thermal insulation materials (such as aluminum silicate fiber).

[0053] The side chain mechanism comprises two side caterpillar belts 3 symmetrically arranged on the two sides of the lower conveying caterpillar belt 1 and the upper conveying caterpillar belt 11. The bottom ends of the two side caterpillar belts 3 are fixedly connected with a plurality of supports 31, and the bottom end of each support 31 is connected with a matching positioning plate 16. The two side caterpillar belts 3 are located between the lower conveying caterpillar belt 1 and the upper conveying caterpillar belt 11. When the lifting driving motor 15 drives the upper conveying caterpillar belt 11 to lift, the bottom end of the side caterpillar belt 3 is flush with the top end of the lower conveying caterpillar belt 1. The side caterpillar belt 3 cooperates with the upper conveying caterpillar belt 11 and the lower conveying caterpillar belt 1 to form a dynamic guide channel, so that the material is always constrained by both sides in the conveying process, and the lateral deviation and torsion are inhibited.

[0054] Referring to Figure 2 , the two side caterpillar belts 3 can be used to position the material at the inlet, thereby facilitating subsequent pressure conveying.

[0055] The collecting assembly comprises two collecting pieces 5 symmetrically arranged below the two sides of the shell 4. The outer ends of the two collecting pieces 5 are vertically inserted with insertion rods 51, which are vertically detachably inserted into the outer ends of the collecting pieces 5. The top ends of the two insertion rods 51 are fixedly connected with connecting plates 52, which are bent. The other ends of the two connecting plates 52 are rotatably connected with the outer walls of the adjacent slide rods 46.

[0056] The bottom ends of the two collecting pieces 5 are fixedly connected with protrusions parallel to the extension direction of the positioning plate 2. Sliding grooves are formed in the two positioning plates 2 below the protrusions, and the sliding grooves are slidably connected with the protrusions. When the slide rod 46 slides along the scraper 45 and swings, the collecting piece 5 is pushed to reciprocally slide.

[0057] Referring to Figure 6 and Figure 8 , with the rotation of the scraper 45, the sliding rod 46 can be guided to slide along the arc-shaped positioning groove 42, so that the whole collecting device 5 can be pushed to reciprocally slide horizontally along the positioning plate two 17 by the connecting plate 52, the collected water glue is homogenized, and the whole collecting device 5 is connected with the inserting rod 51 in a plug-in manner, so that the collecting device 5 is convenient to disassemble and clean.

[0058] The principle of the present application is as follows:

[0059] The present application can quickly guide the input plate to the center position by the lower conveying track 1 and the upper conveying track 11 driven by the track servo motor and cooperating with the side tracks 3 arranged on both sides, can drive the lifting screw piece one 13 and the lifting screw piece two 14 to move downward synchronously by the lifting driving motor 15, and can make the upper conveying track 11 connected with the lifting screw piece two 14 press down to the surface of the plate, and can adopt different heating modes according to needs, for example, an electric heating mode, cooperating with the circulating mechanism and the circulating air duct 21 to control the temperature of the plate material in the conveying process.

[0060] When the plate is conveyed to the direction of the discharge port, the track plates of the lower conveying track 1 / upper conveying track 11 will abut against the scrapers 45 arranged on the upper and lower ends in sequence, the abutment of the scrapers 45 and the track plates is always maintained under the elastic pushing of the spring 43, and the contact between the abutment wheel 61 and the inner side surface protrusion of the track can make the scraper 45 elastically abut against the outer surface of the track, and the scraper 45 can reciprocally move vertically, then slide along the protrusion of the horizontal plate 41 by the helical groove 47, and finally realize the intermittent change of the angle of the scraper 45 by α, and with the driving of the lower conveying track 1 / upper conveying track 11, the water glue scraped by the abutment can be collected into the collecting device 5.

[0061] With the reciprocating α angle rotation of the scraper 45, the sliding rod 46 will slide along the positioning groove 42, and the inserting rod 51 and the collecting device 5 will reciprocally slide horizontally at the positioning plate two 17 by the rotary connection of the connecting plate 52.

[0062] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and range of the equivalent elements of the claims are intended to be embraced in the present application. Any reference signs in the claims should not be considered as limiting the claims involved.
