Description

Technical Field

[0001] The invention relates to the technical field of wet embryo transfer, and in particular to an arc guide rail servo synchronous follower device. Background Art

[0002] At present, pulp molding is a green and environmentally friendly product made from plant fiber pulp or waste paper products that can be completely naturally degraded and recycled as the basic material. The production process of pulp molding is completed by pulping, adsorption molding, wet embryo transfer, hot pressing and shaping. It is widely used in food and medicine holding, electrical appliance packaging, planting and seedling cultivation, medical utensils, handicraft base and fragile product cushioning packaging.

[0003] In the related art, the invention with application number CN202010641726.9 discloses a fully automatic rotary pulp molding hot pressing and shaping integrated production equipment, including a pulping wet embryo forming device, a rotary pulp molding hot pressing and shaping device, and a rotary wet embryo transfer device; the rotary wet embryo transfer device is arranged between the wet embryo forming device and the hot pressing and shaping device, and the rotary wet embryo transfer device absorbs the wet embryos in the pulping wet embryo forming device one by one during the rotation process, and when one of the wet embryo transfer arm structures sends the wet embryo into the rotary pulp molding hot pressing and shaping device, the other wet embryo transfer arm structure opposite thereto absorbs the wet embryo in the pulping and shaping device, and part of them waits to send the wet embryo into the hot pressing and shaping device, and the other part waits to enter the pulping station. The present invention has the characteristics of reasonable layout, compact structure, small space occupation, stable and reliable operation, low energy consumption, and high production efficiency, and can realize continuous automatic production of wet embryo forming, wet embryo transfer, hot pressing and shaping and other processes. A follower push rod is fixedly installed on one side of each hot-pressing lower mold structure in the vertical direction, and a follower pulley that can contact the follower push rod is fixedly installed on each wet embryo adsorption mold; the first arc track, the second arc track and the rotating frame are cocentric; and also include a reset spring, one end of which is fixedly connected to the arc guide plate, and the other end of which is fixedly connected to the lifting installation plate. During operation, when the wet embryo adsorption mold rotates to the second position, the wet embryo adsorption mold is located directly above the hot-pressing lower mold structure, the follower push rod contacts the follower pulley, and the wet embryo adsorption mold is driven by the lifting drive mechanism to descend in the vertical direction, and the wet embryo adsorption mold is molded with the hot-pressing lower mold structure. Since the follower push rod rotates at a uniform speed with the hot-pressing lower mold structure, the follower push rod will apply a horizontal driving force to the follower pulley and the wet embryo adsorption mold. When the follower push rod wet embryo adsorption mold is subjected to the horizontal driving force of the follower push rod, the wet embryo adsorption mold is horizontally translated relative to the wet embryo transfer arm according to the trajectory of the arc guide rail under the constraint of the arc guide follower mechanism, so that The wet embryo adsorption mold rotates at a uniform speed with the hot pressing lower mold structure, ensuring that the wet embryo adsorption mold is always located directly above the hot pressing lower mold structure during the mold closing process, thereby improving the ability of the wet embryo adsorption mold to accurately transfer the wet embryo to the hot pressing lower mold structure; when the wet embryo adsorption mold is closed with the hot pressing lower mold structure, the wet embryo adsorption mold releases the wet embryo, causing the wet embryo to fall into the hot pressing lower mold structure, and the wet embryo adsorption mold is driven by the lifting drive mechanism to rise in the vertical direction and return to the preset height position; when the follower push rod is separated from the follower pulley, the horizontal driving force on the wet embryo adsorption mold disappears, and the reset spring pulls the wet embryo adsorption mold back to the initial horizontal position. However, the above structure still has the following problems: since the arc-shaped guide follower mechanism is passively driven by the follower push rod, mechanical shock is inevitable, and there are inevitably disadvantages of poor stability and poor reliability. Summary of the invention

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] When the driving motor of the present invention is started and runs at a speed and acceleration corresponding to the movement of the hot pressing and shaping mold, its output shaft drives the driving wheel to rotate through the spline shaft. The curved groove on the outer surface of the driving wheel generates friction with the traction rope, thereby driving the traction rope to move. The first end of the traction rope is connected to the first end of the arc guide plate, and the second end is finally connected to the second end of the arc guide plate through a series of paths (including the first arc track, the guide groove of the double-groove guide wheel, the curved groove, etc.). Therefore, when the traction rope moves, it will drive the arc guide plate to follow synchronously along the arc track. At the same time, the first guide wheel and the second guide wheel on the lifting installation plate rotate along the first arc track and the second arc track respectively., ensuring that the relative position between the lifting installation plate and the arc guide plate is stable. Compared with the traditional gear transmission method, the present invention drives the arc guide plate to move by the traction rope line pulling method, which has the characteristics of strong environmental adaptability, no lubrication, no pollution, stable and reliable synchronous transmission, high motion accuracy, light action quality (weight), low consumption and high efficiency, convenient manufacturing, installation and maintenance, and low cost, as follows:

[0032] 1. The traction rope line pulling method is completely insensitive to the unavoidable harsh environment of pulp molding production, such as humidity, splashing of wet pulp, and flying dust after pulp drying. This is because the traction rope itself is not affected by these environmental factors and can maintain stable, reliable and accurate transmission performance for a long time, while traditional gear transmission may cause tooth surface wear, stagnation or failure due to humidity, dust, etc.

[0033] 2. The traction rope pulling method does not require oiling and lubrication, thus completely avoiding machine and product contamination caused by mechanical lubrication. It is also extremely convenient to clean and maintain.

[0034] 3. The soft high-tension traction rope is used to accurately convert the movement of the servo motor into the synchronous movement of the wet embryo mold following the shaping mold. This transmission method has a transmission accuracy no less than that of traditional gears, which can ensure the stability and reliability of the production process.

[0035] 4. Compared with gear transmission, the traction rope pulling method can significantly reduce the weight of the entire system, especially the motion system. This is because the traction rope itself is light in weight and does not require complex components such as gear boxes and transmission shafts; reducing weight not only reduces the energy consumption of the system, but also reduces or avoids impact and vibration during movement, further improving the efficiency, stability and reliability of the system.

[0036] 5. The components of the traction rope are relatively simple, and the manufacturing difficulty and cost are very low. Due to the small number of components and simple structure, the installation process is more convenient, shortening the production and installation cycle. The maintenance of the traction rope is relatively simple, and the use and maintenance costs are very low. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] Embodiment 1:

[0056] Please refer to Figure 1-10 As shown, this embodiment provides an arc guide servo synchronous follower device, including an arc guide follower mechanism 10 and a motor drive mechanism 20;

[0057] Specifically, the arc-shaped guide follower mechanism 10 includes an arc-shaped guide plate 11 and a lifting installation plate 12; a first arc-shaped track 111 is provided on one side wall of the arc-shaped guide plate 11, and a second arc-shaped track 112 is provided on the other opposite side wall; the first arc-shaped track 111 and the second arc-shaped track 112 are co-centered; a first guide wheel 121 and a second guide wheel 122 are provided on the bottom surface of the lifting installation plate 12, and the first guide wheel 121 and the second guide wheel 122 cooperate with the first arc-shaped track 111 and the second arc-shaped track 112 to form an arc-shaped motion pair respectively;

[0058] Specifically, the motor drive mechanism 20 includes a motor mounting plate 21, a drive motor 22, a drive wheel 23, a double-groove guide wheel 24, and a traction rope 25;

[0059] One end of the motor mounting plate 21 is mounted on the lifting mounting plate 12;

[0060] The driving motor 22 is mounted on the motor mounting plate 21, and the output shaft 221 of the driving motor 22 passes through the bottom surface of the motor mounting plate 21 and extends vertically downward;

[0061] The driving wheel 23 is mounted on the output shaft 221 of the driving motor 22, and a curved groove 231 is formed on the outer surface of the driving wheel 23;

[0062] The double-groove guide wheel 24 is installed on the bottom surface of the lifting installation plate 12 and is located in the middle of one side of the first arc-shaped track 111. A first annular guide groove 241 and a second annular guide groove 242 are formed on the outer surface of the double-groove guide wheel 24.

[0063] The first end of the traction rope 25 is connected to the first end of the arc guide plate 11, and the second end thereof enters the first arc track 111 from the left end, then passes through the middle position of the first arc track 111, and successively bypasses the first circular guide groove 241, the curved groove 231, and the second circular guide groove 242 before entering the first arc track 111 again, and finally passes through the right end of the first arc track 111 and is connected to the second end of the arc guide plate 11.

[0064] On the basis of the above structure, when the driving motor 22 is started and runs at the speed and acceleration corresponding to the movement of the hot pressing and shaping mold, its output shaft 221 drives the driving wheel 23 to rotate. The curved groove on the outer surface of the driving wheel 23 generates friction with the traction rope 25, thereby driving the traction rope 25 to move. The first end of the traction rope 25 is connected to the first end of the arc guide plate 11, and the second end is finally connected to the second end of the arc guide plate 11 through a series of paths (including the first arc track 111, the guide groove of the double groove guide wheel 24, the curved groove 231, etc.). Therefore, when the two ends of the traction rope 25 move left and right, the arc guide plate 11 will be driven to follow synchronously along the arc track under the constraint of the guide wheel. At the same time, the first guide wheel 121 and the second guide wheel 122 on the lifting installation plate 12 roll along the first arc track 111 and the second arc track 112 respectively, ensuring the relative position stability between the lifting installation plate 12 and the arc guide plate 11. Compared with the gear transmission mode, the present invention drives the arc guide plate 11 by the traction rope 25 line pulling mode in the arc guide rail servo synchronous follower device, showing significant advantages, and has the characteristics of strong environmental adaptability, no need for lubrication, no pollution, stable and reliable synchronous transmission, high motion accuracy, light motion mass (weight), low consumption and high efficiency, convenient manufacturing, installation and maintenance, and low cost, as follows:

[0065] 1. The traction rope 25 wire-pull transmission has a high adaptability to the unavoidable harsh environment of pulp molding production, such as humidity, splashing of wet pulp, and flying dust after pulp drying. This is because the traction rope 25 itself is not affected by these environmental factors, and can be maintained for a long time without maintenance to maintain stable and reliable transmission performance that meets the requirements of motion accuracy, while traditional gear transmission may cause tooth surface wear, stagnation or failure due to humidity, dust, etc.

[0066] 2. The 25-wire pulling transmission of the traction rope does not require oiling and lubrication, thus completely avoiding machine and product contamination caused by mechanical lubrication. It is also extremely convenient to clean and maintain.

[0067] 3. The soft high-tension traction rope 25 is used to accurately convert the movement of the servo motor into the synchronous movement of the wet embryo mold following the shaping mold. This transmission method has a transmission accuracy that is no less than that of traditional gears, which can ensure the stability and reliability of the production process. 4. Compared with gear transmission, the traction rope 25 wire-pull transmission can significantly reduce the weight of the entire system, especially the motion system. This is because the traction rope 25 itself is light in weight and does not require complex components such as gear boxes and transmission shafts; reducing weight not only reduces the energy consumption of the system, but also reduces or avoids impact and vibration during movement, further improving the efficiency, stability and reliability of the system.

[0068] 5. The components of the traction rope 25 are relatively simple, and the manufacturing difficulty and cost are very low. Due to the small number of components and simple structure, the installation process is more convenient and the installation cycle is shortened. The maintenance of the traction rope 25 is relatively simple, and the use and maintenance costs are very low.

[0069] In a preferred embodiment of the present invention, the first annular guide groove 241 and the second annular guide groove are staggered in the axial direction of the double-groove guide wheel 24, and both have the same shape and diameter.

[0070] On the basis of the above structure, when the traction rope 25 bypasses the double-groove guide wheel 24, since the first annular guide groove 241 and the second annular guide groove are staggered in the axial direction and have the same diameter, the two ends of the traction rope 25 enter the two guide grooves respectively and move in the same direction and speed on the double-groove guide wheel 24. This staggered design ensures that the traction rope 25 will not be entangled or knotted when bypassing the double-groove guide wheel 24. The staggered guide groove design reduces the friction of the traction rope 25 during the transmission process, reduces energy loss, and thus improves the transmission efficiency. At the same time, this design also reduces the wear of the traction rope 25 and extends the service life of the traction rope 25.

[0071] In a preferred embodiment of the present invention, the curved groove 231 includes all continuous curved grooves without abrupt points, such as a sine curve groove or a wave groove.

[0072] In a preferred embodiment of the present invention, the curved groove 231 is a shallow wavy groove evenly and symmetrically distributed along the circumference of the driving wheel. In this way, the wavy groove has a rounded crest and trough design, which can adapt to traction ropes 25 of different diameters and materials, improving the versatility of the device. The rounded crest and trough design can effectively increase the contact area with the traction rope 25, thereby increasing the mutual friction to avoid slipping, thereby enhancing the transmission stability and reliability.

[0073] In a preferred embodiment of the present invention, it further includes a spline shaft 26 and a limit plate 27;

[0074] A flat key is provided on the output shaft 221 of the driving motor 22;

[0075] The limit plate 27 is locked to the bottom of the output shaft 221 of the driving motor 22 by connecting screws;

[0076] A flat keyway 261 is formed in the middle through hole of the spline shaft 26, and the spline shaft 26 cooperates with the flat key of the output shaft 221 through the flat keyway 261; the spline shaft 26 is locked on the limit plate 27 by connecting screws;

[0077] An inner spline hole 232 is formed in the middle of the driving wheel 23, and the driving wheel 23 forms a clearance fit with the outer spline 262 of the spline shaft 26 through the inner spline hole 232. The driving wheel 23 can move freely up and down along the axial direction of the spline shaft 26, and is restricted from escaping from the spline shaft 26 by the limit plate 27.

[0078] On the basis of the above structure, the driving wheel 23 is not rigidly fixed in a certain position, but can float up and down along the axial direction of the spline shaft 26. This design gives the driving wheel 23 a certain degree of freedom, so that it can adjust its position adaptively to match the actual position of the traction rope 25 when entering and exiting the curved groove 231. When the traction rope 25 has a slight up and down position difference when entering and exiting the curved groove 231, the driving wheel 23 will immediately sense this deviation and automatically adjust its position by moving up and down along the spline shaft 26. This adaptive adjustment can ensure that the traction rope 25 always maintains optimal contact with the curved groove 231, thereby reducing or avoiding mechanical shock and vibration. The spline connection between the spline shaft 26 and the driving wheel 23 not only transmits torque, but also allows this slight axial movement. The precise matching of the splines ensures the stability and accuracy of the transmission, and at the same time, no additional friction or wear will be generated due to axial movement. The presence of the limit plate 27 not only limits the axial movement of the spline shaft 26, but also prevents the driving wheel 23 from coming off the spline shaft 26, thus providing a solid safety guarantee for the entire transmission system. The entire design adopts a modular structure, and the connection between the various components is simple and clear, which is convenient for quick installation, disassembly and daily maintenance.

[0079] In a preferred embodiment of the present invention, the axial length of the spline shaft 26 is greater than the axial length of the driving wheel 23. Thus, the extended spline shaft 26 design enables the device to more flexibly adapt to driving wheels 23 of different sizes and shapes. Even if the axial length of the driving wheel 23 changes, the spline shaft 26 can still provide sufficient support and matching length, ensuring the reliability and accuracy of the transmission.

[0080] In a preferred embodiment of the present invention, two traction rope fixing seats 28 are further included. The two traction rope fixing seats 28 are respectively installed on two side walls of the arc guide plate 11 adjacent to the first arc track 111; the two ends of the traction rope 25 are respectively connected to the two traction rope fixing seats 28.

[0081] Based on the above structure, the traction rope fixing seat 28 provides a stable support point for the traction rope 25, ensuring the stability and reliability of the traction rope 25 in the power transmission process. No matter how the arc guide plate 11 moves, the traction rope 25 can maintain a constant tension, thereby achieving stable traction force transmission.

[0082] In a preferred embodiment of the present invention, an adjustment assembly 30 is further included, and the adjustment assembly 30 includes a fixing plate 31, a plurality of connecting screws 32 and a tensioning cam 33;

[0083] One end of the motor mounting plate 21 is provided with a plurality of long waist holes 211;

[0084] The lifting installation plate 12 is provided with a plurality of threaded holes corresponding to the above-mentioned long waist holes one by one;

[0085] The fixing plate 31 is provided with a plurality of nail through holes corresponding one to one with the plurality of threaded holes on the lifting and mounting plate;

[0086] The connecting screws 32 are sequentially passed through the nail through holes, the long waist holes 211 and threadedly connected with the threaded holes of the lifting mounting plate 12. A plurality of connecting screws 32, a plurality of nail through holes, and a plurality of threaded holes are arranged one by one to mount the motor mounting plate 21 on the lifting mounting plate 12. When the connecting screws 32 are not tightened, the motor mounting plate can be allowed to move along the length direction of the long waist holes 211 so as to adjust the tension of the traction rope 25 to the best.

[0087] The tensioning cam 33 is installed on the lifting mounting plate 12 by means of a fastening screw 34. The tensioning cam 33 abuts against the motor mounting plate 21. The tensioning cam 33 is rotated by a wrench tool to adjust the eccentricity of the tensioning cam 33, so that the tensioning cam 33 drives the motor mounting plate 21 to move along the length direction of the long waist hole 211, so as to adjust the tension of the traction rope 25.

[0088] On the basis of the above structure, by adjusting the eccentricity of the tensioning cam 33, the movement of the motor mounting plate 21 along the length direction of the long waist hole 211 can be accurately controlled, and then the motor can be driven to move through the motor mounting plate 21. This fine-tuning ability allows the tension of the traction rope 25 to be adjusted very finely, thereby meeting the strict requirements of tension in different application scenarios. The tight connection between the connecting screws 32, the fixing plate 31, the motor mounting plate 21 and the lifting mounting plate 12 forms a stable overall structure. This design not only enhances the stability of the system, but also ensures the accuracy and reliability during the transmission process. The design of the long waist hole 211 provides a certain amount of activity space for the motor mounting plate 21, making the installation and debugging process more flexible. Users can easily adjust the position of the motor mounting plate 21 according to actual needs to achieve the best transmission effect.

[0089] In a preferred embodiment of the present invention, the tensioning cam 33 is fixedly mounted on the lifting mounting plate 12 by means of a fastening screw 34. The upper portion of the tensioning cam 33 is a regular polygonal protrusion (a regular hexagon in this embodiment) along the axial direction, so as to facilitate precise adjustment using a wrench tool. When the fastening screw 34 has not been tightened, the tensioning cam 33 can be rotated around the fastening screw 34 using a wrench, thereby achieving a slight adjustment of the tension of the traction rope 25. When the tensioning cam 33 is adjusted to the best, the fastening screw 34 can ensure that the tensioning cam 33 is firmly fixed on the lifting mounting plate 12. This avoids changes in tension caused by vibration or external force during operation, thereby maintaining the stability and consistency of the tension of the traction rope 25. In a preferred embodiment of the present invention, the traction rope is a soft and strong stainless steel wire rope with high tension. Other manufacturing materials are not excluded, but are not limited to: metal, plastic, animal and plant fibers and their braids.

[0090] In a preferred embodiment of the present invention, the driving motor is a high-performance servo motor with complete servo functions, and other prime movers such as stepper motors with communication capabilities and capable of automatic synchronous control according to external and self-encoder feedback signals are not excluded.
