Description

Technical Field

[0001] This invention relates to the field of corrugated roll processing technology, and in particular to an angle-adjustable rotary table for a corrugated grinding machine. Background Technology

[0002] Corrugated rolls are the most important component of corrugated cardboard production equipment, and are key parts of singlefacers. Corrugated rolls are divided into upper and lower corrugated rolls, both with toothed surfaces. The two rolls are paired and meshed, and their meshing mechanism differs from typical gear drives. The lower corrugated roll is the driving roll, with a gear at its shaft end. An electric motor drives the lower corrugated roll through a reduction gear. The upper corrugated roll is the driven roll, relying on the meshing of the teeth of the upper and lower rolls for transmission. During the manufacturing process, a corrugated grinding machine is used to polish the corrugated rolls, forming corrugated teeth. The corrugated grinding machine uses a turntable connected to the end of the corrugated roll to control its rotation, thereby creating uniform corrugated teeth.

[0003] The use of existing turntables varies depending on the processing steps of the corrugated rollers. For example, during the initial grinding process, the turntable drives the corrugated rollers to grind evenly at a set speed. During the fine grinding process, the drive motor controls the turntable to rotate at a certain angle to grind a single tooth groove. As described above, the main purpose is to control the rotation of the corrugated rollers (divided into uniform rotation and fixed-angle rotation). During the grinding process, external environmental factors can affect the turntable. These factors can form grinding particles that may intrude into the turntable bearings and encoder disks, causing angle positioning failure. External vibrations can also cause the turntable to resonate, leading to increased rotational amplitude, unstable contact between the grinding wheel and the workpiece, and "vibration marks" on the tooth surface after rough grinding. Furthermore, during the rotation control process, unbalanced mass or insufficient allowance at the connection points of the corrugated rollers can amplify the vibration. Existing turntables lack auxiliary control mechanisms to reduce the impact of external factors and improve processing accuracy and forming effect. Summary of the Invention

[0004] The present invention addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The present invention provides an angle-adjustable rotary table for a corrugated grinding machine to solve the technical problems of existing rotary tables being affected by external factors, resulting in eccentric rotation and inability to perform precise positioning during the process of controlling the rotation of the corrugated rollers.

[0005] The present invention adopts the following technical solution: an angle-adjustable rotary table for a corrugated grinding machine, including a Haver head for clamping the end of the corrugated roller, and further comprising; The turntable transmission assembly is connected to the end of the Haval head to allow the Haval head to rotate. The drive motor is connected to the turntable transmission assembly, and the driving force of the drive motor is supplied to the Haval head to rotate through the turntable transmission assembly; The auxiliary control mechanism is installed on the turntable transmission assembly. It is used to limit the angle deflection, thereby reducing the deflection angle deviation caused by gear wear, and the control deflection angle is adjustable. The transmission body is installed in the turntable transmission assembly and the auxiliary control mechanism assembly, and is used by the auxiliary control mechanism to detect the rotation angle of the turntable transmission assembly.

[0006] Furthermore, the transmission body is slidably mounted on the turntable transmission assembly and fixed by bolts. An adjustment groove for adding counterweights is provided on the upper part of the transmission body. The end of the transmission body is connected to the rotatable side of the mating housing. The mating housing is connected to the turntable transmission assembly and is hollow.

[0007] Furthermore, the auxiliary control mechanism includes an adjustment component and an auxiliary limiting component. The adjustment component includes several conical blocks connected to the transmission body, and the conical blocks are located inside the mating housing. In the initial state, the friction between the conical blocks and the inner surface of the mating housing is low. The mating housing is provided with a control connecting ring, a limiting ring, and an abutting connecting ring in sequence from the inside out. The inner ring of the limiting ring is provided with a connecting groove. The control connecting ring is connected to the connecting groove through a rotating connecting block. An abutting ball that serves as a limit is provided between every two adjacent conical blocks. The displacement of one side of the abutting connecting ring is controlled by a first electrically controlled telescopic rod.

[0008] Furthermore, the surface of the conical block and the contact surface of the mating shell are made of a material that produces abnormal noise due to excessive friction, such as hard plastic + hard material.

[0009] Furthermore, the control component includes a screw connected to an abutment ball, the screw being threadedly connected to a control connecting ring, and a mating gear at the end of the screw. A plurality of mounting slots are provided on the limiting ring, each mounting slot being connected to a magnetic damping rack via a guide rod. An electromagnetic damping block is provided in each mounting slot to cooperate with the magnetic damping rack. The mating gear meshes with the magnetic damping rack. The screw end has a T-shaped cross-section and is slidably connected to the abutment connecting ring. The limiting ring cooperates with an electrically controlled plug rod, and one side of the limiting ring is connected to a rotating motor, which drives the limiting ring to rotate.

[0010] Furthermore, in the initial state, the screw has low contact force with the control connecting ring.

[0011] Furthermore, a number of insertion holes are equidistantly arranged inside the limiting ring, and the limiting ring is limited by the cooperation of the insertion holes and the electronically controlled insertion rod.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: During use, by adding an auxiliary control mechanism to the turntable, the wear caused by inertia on the gear set and bearings can be reduced during fine grinding at a small angle. (During use, due to the large size of the corrugated roller, although the drive motor stops rotating each time braking is applied, the turntable actually relies on the hard contact of the internal gear set to achieve the braking effect, resulting in all the inertial force acting on the braking component, lacking a component to distribute the force.) This auxiliary control mechanism can achieve the distribution of the force, thereby alleviating the wear problem caused by braking. Secondly, although it alleviates the wear problem caused by braking, wear caused by external factors is still inevitable with continuous use, resulting in a margin of error during braking. This structure addresses this issue by using internal components to transform the tendency of the deflection roller into a relative tendency, reducing its inertia and thus providing auxiliary restraint and improving the accuracy of the deflection angle. Furthermore, considering the different deflection angles of different corrugated rollers during structural design, this structure also features an adjustable angle. The intervention angle of the auxiliary control mechanism can be adjusted according to the required deflection angle for corrugated roller processing, effectively expanding its applicability. Secondly, if eccentricity occurs, the mechanism will issue a signal during rotation to alert the operator. (In the initial state, the contact force between the conical block and the inner wall of the mating housing is small, resulting in relatively low friction. However, if eccentricity occurs, the turntable will not exhibit obvious eccentricity during processing due to the influence of the sliding base and bearing housing, but there will be a tendency towards eccentricity. This increases the contact force between the conical block and the mating housing, indirectly increasing friction. If the friction is too high, the conical block will produce a sound during rotation due to the influence of its surface material, thus alerting the operator.) In summary, by adding an auxiliary control mechanism to the existing turntable, the inertial wear caused by braking during angle deflection processing can be mitigated, reducing turntable wear caused by hard contact. Furthermore, when gaps inevitably appear on the turntable, this device can be finely adjusted to reduce the impact of these gaps. Moreover, the internal structural parameters can be adjusted as needed to make it suitable for different corrugated roll processing applications. Attached Figure Description

Detailed Implementation

[0016] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0017] The components of the embodiments of the invention described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0018] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] The following is combined with Figures 1 to 8 As shown, an embodiment of the present invention provides an angle-adjustable rotary table for a corrugated grinding machine, including a Haver head 2 for clamping the end of the corrugated roller, and further comprising; Turntable transmission assembly 3 is connected to the end of Haval head 2 to allow Haval head 2 to rotate; Drive motor 4 is connected to turntable transmission assembly 3, and the driving force is supplied to the Haval head 2 to rotate through turntable transmission assembly 3; The auxiliary control mechanism 11 is installed on the turntable transmission assembly 3. It is used to assist in limiting the angle deflection, thereby reducing the deflection angle deviation caused by gear wear, and the control deflection angle is adjustable. Transmission body 1 is installed in the turntable transmission assembly 3 and the auxiliary control mechanism 11 assembly, and is used by the auxiliary control mechanism 11 to detect the rotation angle of the turntable transmission assembly 3.

[0022] During operation, it is important to note that the Haval head 2 clamps the workpiece. To facilitate clamping and installation, the Haval head 2 employs a design with two detachable semi-circular plates. The remaining drive motor 4 and turntable transmission assembly 3 are existing drive mechanisms. Internally, they transmit rotational power to the Haval head 2 through several transmission gear sets or other transmission components, similar to a lathe. Rotation is controlled by the drive motor 4, and the auxiliary controller of the drive motor 4 controls the rotation angle. In this design, the basic angle control of the turntable is also controlled by the drive motor 4. The auxiliary control mechanism 11 only serves as an auxiliary guide. To reduce wear, an additional lubricating oil circulation route can be added to the turntable transmission assembly 3. Through the cooperation of the oil tank and the pressure pump, the turntable transmission assembly 3 can be circulated with oil to prevent wear of internal transmission components due to lack of lubrication. (It should also be noted that the auxiliary control mechanism 11 is only used to limit the position, reduce wear on the transmission group, extend the service life of the transmission group, and prevent excessive movement due to clearance.)

[0023] Specifically, the transmission body 1 is slidably mounted on the turntable transmission assembly 3 and fixed by bolts. An adjustment groove 102 for adding counterweights is provided inside the transmission body 1. The end of the transmission body 1 is rotatably connected to the mating housing 103. The mating housing 103 is connected to the turntable transmission assembly 3 and is hollow.

[0024] During operation, when the turntable inside the turntable transmission assembly 3 rotates via the transmission body 1 (this turntable is the part connected to the Haval head 2; the drive motor 4 drives the turntable on the turntable transmission assembly 3 to rotate, and the rotation of the turntable drives the Haval head to rotate; the rest of the housing of the turntable transmission assembly 3 is fixed and does not participate in the rotational movement), the transmission body 1 is actually connected to the turntable inside the turntable transmission assembly 3. Therefore, the transmission body 1 will rotate synchronously with the turntable of the turntable transmission assembly 3. At the beginning of installation, the turntable transmission assembly 3 needs to be restored to its initial state, that is, the Haval head 2 is in a specific rotational position (this position is the installation position or debugging position). The turntable transmission assembly 3 has a vertical slot, and the transmission body 1 is equipped with a plug-in block. The plug-in block is connected to the vertical slot. The slots correspond, and then they are locked with bolts or other locking parts. There are several ways to connect the transmission body 1 and the conical block 115. One way is to directly connect the transmission body 1 and the conical block 115. During the installation of the transmission body 1, the conical block 115 can be directly inserted into the mating housing 103. At this time, the rotatable side plays a sealing role to prevent processing dust from entering. Another way is to connect the rotatable side to the conical body. The rotatable side cannot be disassembled. During the installation of the transmission body 1, since it is in the initial position, there is a hole on the transmission side and a plug at the end of the transmission body 1. The plug of the transmission body 1 is inserted into the hole on the transmission side. The fundamental purpose of the above two methods is to allow the conical block 115 to move with the Haval head 2, thereby assisting in judgment.

[0025] Specifically, the auxiliary control mechanism 11 includes an adjustment component and an auxiliary limiting component. The adjustment component includes several conical blocks 115 connected to the transmission body 1, and the conical blocks 115 are located inside the mating housing 103. In the initial state, the friction between the conical blocks 115 and the inner surface of the mating housing 103 is low. The mating housing 103 is provided with a control connecting ring 116, a limiting ring 119 and an abutting connecting ring 111 in sequence from the inside out. The inner ring of the limiting ring 119 is provided with a connecting groove 1191. The control connecting ring 116 is connected to the connecting groove 1191 through a rotating connecting block 1161. An abutting ball 114 that plays a limiting role is provided between each two adjacent conical blocks 115. The displacement of one side of the abutting connecting ring 111 is controlled by a first electrically controlled telescopic rod 112.

[0026] Specifically, the contact surface between the conical block 115 and the mating housing 103 is made of a material that causes abnormal noise due to excessive friction, such as hard plastic + hard material.

[0027] During operation, the use of two different materials is intended to enhance the signal warning effect. Abnormal noises can clearly indicate the occurrence of eccentricity, facilitating operator judgment.

[0028] Specifically, the connecting groove 1191 adopts a T-shaped groove or a vertical groove, so that the limiting ring 119 can follow the horizontal movement of the control connecting ring 116.

[0029] Specifically, the control component includes a screw 1112 connected to the contact ball 114, the screw 1112 being threadedly connected to the control connecting ring 116, and a mating gear 1111 being provided at the end of the screw 1112. A plurality of mounting slots 1192 are provided on the limiting ring 119, each mounting slot 1192 being connected to a magnetic damping rack 117 via a guide rod 118. An electromagnetic damping block 110 is provided in each mounting slot 1192 to cooperate with the magnetic damping rack 117. The mating gear 1111 meshes with the magnetic damping rack 117. The end of the screw 1112 has a T-shaped cross-section and is slidably connected to the contact connecting ring 111. The limiting ring 119 is used in conjunction with the electrically controlled plug 113. One side of the limiting ring 119 is connected to a rotating motor 1113, which drives the limiting ring 119 to rotate.

[0030] Specifically, in the initial state, the screw 1112 and the control connecting ring 116 have low contact force.

[0031] In the initial state, the contact force between the screw 1112 and the control connecting ring 116 is low. Therefore, when the screw 1112 is rotated, it can rotate. Due to the threaded connection between the control connecting ring 116 and the screw 1112, the rotation of the screw 1112 can cause displacement. However, if the contact force is increased (i.e., the friction between the screw 1112 and the contact wall of the control connecting ring 116 is increased; to make this friction force more intuitive, the screw 1112 can be made of a plastic material with a certain degree of plasticity. When the extrusion pressure is large, slight deformation will occur, thus increasing the friction force more significantly and hindering its normal rotation), the screw 1112 cannot rotate normally. That is, the screw 1112 will not rotate when subjected to external forces, but will move accordingly.

[0032] Specifically, a number of insertion holes are equidistantly arranged inside the limiting ring 119, and the limiting ring 119 is limited by the cooperation of the insertion holes and the electronically controlled insertion rod 113.

[0033] During operation, the insertion holes and the electrically controlled insertion rod 113 within the limiting ring 119 are also designed for rotation control. The setting of the insertion hole angle gap is based on the minimum value of the corrugated roller rotation angle. Normal corrugated rollers are divided into three types: A, B, and C, with an average gap difference of 4 cm. In this case, the insertion hole angle gap can be set to 2 cm for adaptation. If the corrugated roller requires special processing during the manufacturing process, resulting in model incompatibility, it can be disassembled. During disassembly, the entire auxiliary control mechanism 11 is removed, and the bolts on several rotating connecting blocks 1161 and the control connecting ring 116 are removed to replace the limiting ring 119, ensuring that its gap meets the deflection gap requirements.

[0034] Working principle: The grinding process of corrugated rollers is mainly divided into fine grinding and coarse grinding. During the rough grinding stage, the drive motor 4 drives the Haval head 2 to rotate via the turntable transmission assembly 3. The Haval head 2 clamps the workpiece, allowing it to rotate. During the rough grinding process, the workpiece rotates continuously, thus roughing out the material and removing the rough material at a relatively fast speed. Therefore, it is not necessary to intervene too much in the deflection angle of the drive motor 4 (i.e., no auxiliary control mechanism 11 needs to be involved). The first electrically controlled telescopic rod 112 is retracted by the operator. The first electrically controlled telescopic rod 112 is connected to the abutting connecting ring 111. The abutting connecting ring 111 is connected to the control connecting ring 116 via the screw 1112. The control connecting ring 116 is connected to the limiting ring 119 via the rotating connecting block 1161. In this way, the entire component will eventually retract, causing the abutting ball 114, which is located between the two conical blocks 115, to move out. At this time, the presence of the abutting ball 114 will not restrict the conical blocks 115, allowing the conical blocks 115 to perform normal circumferential motion, achieving a rapid roughing effect. Simultaneously, during roughing, the workpiece exhibits a certain degree of eccentricity due to the influence of clamping or the workpiece's inherent imbalance. While the presence of the Haval head 2 and other auxiliary slides prevents significant changes in its state, the eccentricity persists. Consequently, more force is transferred to the bearing housing, leading to increased wear on the bearing during rotation. (This eccentricity also causes slight vibrations in the workpiece during machining, resulting in wavy surfaces and affecting the machining outcome.) This non-distinct deformation makes it difficult for operators to clearly and promptly determine the initial state (i.e., the normal state without eccentricity). (The text also mentions the cone block 1, but this seems unrelated to the main topic and is likely a separate, incomplete thought.) 15 is connected to the Haval head 2 via the transmission body 1, causing the conical block 115 to follow and also be affected by eccentricity. The contact force between the conical block 115 and the inner wall of the mating housing 103 is small, resulting in relatively small friction. However, if eccentricity occurs, it will tend to be eccentric, increasing the contact force between the conical block 115 and the mating housing 103, thereby indirectly increasing the friction. If the friction is too large, the conical block 115 will make a sound during rotation due to the influence of its surface material, thus alerting the production personnel. At this time, the staff will check the eccentric position and set a counterweight in the adjustment groove 102 to reduce the eccentricity and reduce wear.

[0035] In the fine grinding stage, after roughing is completed and larger rough materials are removed from the workpiece, each corrugated groove needs to be finely finished to process any remaining material. Grinding is also required. Because each groove needs processing, the drive motor 4 needs to deflect at a certain angle and then stop to grind the corrugated roller. Often, a single corrugated roller requires multiple angle deflections, causing significant inertial wear on its internal transmission components. Therefore, the auxiliary control mechanism 11 intervenes to reduce the wear caused by inertia on the transmission components (restoring them to the adjustment state, i.e., the aligned position). At this point, the required deflection angle of the corrugated roller is known each time. The first electrically controlled telescopic rod 112 is then moved by the operator, ultimately driving the contact ball 11. 4. Movement: At this point, the presence of the contact ball 114 serves to abut against the conical block 115, thereby limiting the movable distance of the conical block 115. Due to the shape of the conical block 115, the gap between the contact ball 114 and the conical block 115 will change (gradually increasing from the outside to the inside). At this point, only the position of the contact ball 114 needs to be controlled to determine the deflection angle. Since the initial control angle is known, the position of the contact ball 114 is determined by the first electrically controlled telescopic rod 112. During the deflection process, when the conical block 115 abuts against the contact ball 114, since the position of the contact ball 114 cannot move, the contact ball 114 can play an auxiliary limiting role in restricting the conical block 115 and distributing its inertial wear. Similarly... If wear occurs, making accurate positioning impossible, the drive motor 4 stops rotating. The conical block 115, after contacting the contact ball 114, still has a tendency to deflect, causing the contact ball 114 to deflect as well. At this time, the control connecting ring 116 is restricted by the electronically controlled rod 113, preventing it from deflecting. Therefore, when the control connecting ring 116 deflects, the meshing gear 1111 on the contact ball 114 meshes and rotates around the magnetic damping rack 117. Subsequently, through the screw 1112, it has an outward extending motion tendency. If the contact ball 114 extends outward, it causes the conical block 115 in contact with it to move in the opposite direction, thus utilizing the excessive movement tendency of the conical block 115 to... The moving contact ball 114 undergoes an additional static change, canceling out the direction of the force and thus limiting the impact of wear on the transmission assembly. This component also requires circular motion. After one limit cycle, the resistance of the electromagnetic damping block 110 increases, causing excessive contact force between the mating gear 1111 and the magnetic damping rack 117. At this point, the mating gear 1111 cannot rotate normally. (That is, it can be understood that the control connecting ring 116 and the limiting ring 119 are connected, but due to the excessive contact force, the screw 1112 cannot rotate and is restricted. At this time, the rotation of the control connecting ring 116 will drive the limiting ring 119 to rotate synchronously.) The electronic control rod 113 retracts, releasing the restriction on the limiting ring 119, and the rotating motor 1113 is started.The control ring 116 rotates at a certain angle, causing the contact ball 114, which was in contact with the conical block 115, to separate and return to its initial state. Then, the electronically controlled plug 113 is inserted into one of the several sockets to complete the reset.
