Technical Field
[0001] This utility model relates to the field of rubber roller positioning technology, specifically a rubber roller positioning device. Background Technology
[0002] Rubber rollers, commonly known as rubber rollers, are roller-shaped products made with a metal or other material core covered with rubber through vulcanization. Proper positioning of rubber rollers ensures their accurate position and orientation within equipment, thereby guaranteeing precise operation during production. Accurate positioning also helps to evenly distribute the force on the roller, preventing excessive localized wear and extending its service life. Utility model patent CN213197249U discloses an outer cylinder positioning device for rubber roller production, including a base. Both sides of the outer surface of the base are provided with sliding grooves. A plurality of positioning holes are evenly distributed on the outer surface of the sliding grooves. A slider is slidably connected to the inner sides of the front and rear ends of the sliding grooves. A pin hole B is provided at the middle position of the outer surface of the slider. A movable block is fixedly installed on the opposite side of the outer surface of the slider. A pin hole A is provided at the middle position of the outer surface of the movable block. A pin post is provided inside the pin hole A, penetrating the pin hole A, the pin hole B, and one of the positioning holes. A vertical plate A is provided at the front of the upper end face of the base. A motor is fixedly installed at the middle position of the front end face of the vertical plate A, and a rotating shaft is fixedly connected to the output end of the motor. The above technical solution, by setting a fixing ring, spring and arc-shaped limiting plate, can support outer cylinders of different diameters. The rubber sleeve on the outer surface of the arc-shaped limiting plate improves the limiting effect of the arc-shaped limiting plate on the outer cylinder and prevents the outer cylinder from sliding back and forth. However, when conveying materials, the rubber rollers are installed on the end of the conveying equipment. The installation positions of rubber rollers of different sizes are not fixed, and the installation distances between the rotating shafts at both ends of the rubber rollers and the corresponding driving components are different. There is a distance between the rubber rollers and the side wall of the conveying equipment. During the conveying operation, the rubber rollers move left and right. After long-term rotation and conveying, the rubber rollers are subjected to uneven force, wear and wear out quickly, shorten their service life, are not convenient for positioning the rubber rollers, and limit their range of movement. Utility Model Content
[0003] The purpose of this invention is to provide a rubber roller positioning device to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: A rubber roller positioning device includes a fixed base and a positioning plate for a liftable and positionable rubber roller mounted on top of the fixed base. The fixed base has inserts near its four corners on its upper surface. A positioning platform is located above the fixed base. Sleeves are located on the lower surface of the positioning platform corresponding to the inserts. Slots are provided at the bottom of each sleeve. A connecting plate is located between the sleeves near their bottoms. An electric push rod is located at the center of the upper surface of the fixed base and the lower surface of the connecting plate. A dual-axis motor is located at the center of the lower surface of the positioning platform. A forward lead screw is located at the end of the right output shaft of the dual-axis motor, and a reverse lead screw is located at the end of the left output shaft of the dual-axis motor. Positioning structures for clamping and positioning the rubber roller are located near both ends of the positioning platform. The positioning structure includes two symmetrical positioning plates. Each positioning plate has a rotating shaft groove at the top center and a cross slide plate at the bottom. Each cross slide plate has a screw hole. A cross groove is formed at the end of the positioning platform corresponding to the cross slide plate. A rubber roller is provided between the two rotating shaft grooves.
[0005] Furthermore, the lower surface of the fixed base is provided with support feet near the four corners. The support feet are L-shaped and each support foot has a fixing hole at its bottom.
[0006] In this invention, the support feet help to secure the bottom of the fixed base to the bottom of the conveying equipment. External screws pass through the fixing holes and are fixedly connected to the bottom of the corresponding conveying equipment, increasing the stability of the fixed base installation.
[0007] Specifically, the bottom of the insertion post is welded and fixed to the top of the fixing seat, the top of the sleeve post is welded and fixed to the bottom of the positioning platform, and the width of the inner wall of the slot is adapted to the width of the outer wall of the insertion post.
[0008] In this invention, the insert and slot are connected to each other, so that the positioning platform can slide up and down in the insert through the sleeve, thereby adjusting the distance between the positioning platform and the fixed seat, and thus adjusting the height of the rubber roller held by the positioning plate.
[0009] It should be noted that the bottom of the electric push rod is fixedly connected to the fixed base by screws. The outer wall of the electric push rod is provided with a control switch, and the control switch is electrically connected to an external power source through a wire. The end of the telescopic arm of the electric push rod is fixedly connected to the bottom of the connecting plate by screws. The connecting plate is welded and fixed to the corresponding sleeve column.
[0010] In this invention, the control switch is activated to extend or shorten the telescopic arm of the electric push rod. When the telescopic arm extends, the positioning platform moves upward, increasing the distance between the positioning platform and the fixed seat. When the telescopic arm shortens, the positioning platform moves downward, decreasing the distance between the positioning platform and the fixed seat. The connecting plate provides a point of force, facilitating the installation of the telescopic arm of the electric push rod.
[0011] Secondly, the cross slide plate and the positioning plate are integrally formed, and the width of the outer wall of the cross slide plate is adapted to the width of the inner wall of the cross slide groove.
[0012] In this invention, the cross-shaped sliding plate and the cross-shaped sliding groove are connected and engaged, which helps the positioning plate to move horizontally and stably on the positioning platform.
[0013] It is worth noting that the dual-axis motor is fixedly connected to the positioning table by screws, and the forward lead screw and the reverse lead screw are respectively welded and fixed to the corresponding output shaft of the dual-axis motor. In addition, the forward lead screw and the reverse lead screw are also threadedly connected to the screw holes on the corresponding cross slide plate.
[0014] In this invention, the control switch on the outer wall of the dual-axis motor is electrically connected to an external power source via a wire. When the control switch is activated, the output shaft of the dual-axis motor rotates. When the output shaft rotates synchronously in the forward direction, the forward lead screw and the reverse lead screw rotate synchronously in the forward direction, enabling the two cross slides to move synchronously outward. When the output shaft rotates synchronously in the reverse direction, the forward lead screw and the reverse lead screw rotate synchronously in the reverse direction, enabling the two cross slides to move synchronously inward. This facilitates the synchronous movement of the two positioning plates towards each other, clamping and positioning rubber rollers of different lengths, preventing the rubber rollers from moving left and right during rotation. Furthermore, during clamping and positioning, the opposing sides of the two positioning plates are close to the outer wall of the rubber roller with a small gap, which does not hinder the flexible rotation of the rubber roller.
[0015] Specifically, the rotating shafts at both ends of the rubber roller are inserted into the corresponding rotating shaft grooves, and the outer diameter of the rotating shaft is adapted to the inner diameter of the rotating shaft groove. The ends of the rotating shafts are inserted into the external driving components through the snap-fit grooves and snap-fit blocks.
[0016] In this invention, the rotating shaft groove facilitates the insertion and engagement of the rubber roller shaft, and the ends of the rotating shaft all pass through the rotating shaft groove. One end of the rotating shaft is inserted and engaged with an external driving component to perform the corresponding rotation engagement of the rubber roller, which facilitates the material conveying and guiding.
[0017] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, by setting up a positioning platform and a fixed base for plug-in cooperation, and with the cooperation of an electric push rod, realizes the height adjustment of the positioning platform to rise or fall. The positioning plates that can move towards each other are symmetrically installed on the positioning platform, and with the cooperation of a dual-axis motor with a forward lead screw and a reverse lead screw, the two positioning plates can move towards each other to clamp and position rubber rollers of different lengths. The lifting adjustment can adjust the height of the clamping rubber rollers, which is convenient for combination with corresponding conveying equipment for conveying.
[0018] 2. This utility model uses support feet and screws through fixing holes to fix the fixing base to the bottom of the conveying equipment. The shaft groove is designed to facilitate the insertion of the shaft of the rubber roller. The rotation of the shaft and the shaft groove does not affect the rotation of the rubber roller tube.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-5 This embodiment provides a technical solution: A rubber roller positioning device includes a fixed base 1 and a positioning plate 3 for a rubber roller that can be lifted and positioned mounted on the fixed base 1. The lower surface of the fixed base 1 is provided with support feet 12 near the four corners. The support feet 12 are L-shaped and each support foot 12 has a fixing hole at its bottom.
[0023] In this invention, the support foot 12 helps to fix the bottom of the fixed base 1 to the bottom of the conveying equipment. External screws pass through the fixing holes and are fixedly connected to the bottom of the corresponding conveying equipment, increasing the stability of the fixed base 1 during installation.
[0024] Furthermore, the upper surface of the fixing base 1 is provided with inserts 10 near the four corners, the fixing base 1 is provided with a positioning platform 2 above it, the lower surface of the positioning platform 2 is provided with sleeves 20 corresponding to the inserts 10, the bottom of each sleeve 20 is provided with a slot 200, the bottom of the insert 10 is welded to the top of the fixing base 1, the top of the sleeve 20 is welded to the bottom of the positioning platform 2, and the width of the inner wall of the slot 200 is adapted to the width of the outer wall of the insert 10.
[0025] In this utility model, the insert post 10 and the slot 200 are inserted and engaged, so that the positioning platform 2 can slide up and down in the insert post 10 through the sleeve post 20, thereby realizing the distance adjustment between the positioning platform 2 and the fixed seat 1, and thus realizing the height adjustment of the rubber roller 5 held by the positioning plate 3.
[0026] Specifically, a connecting plate 21 is provided near the bottom between the sleeves 20. An electric push rod 11 is provided at the center of the upper surface of the fixed seat 1 and the lower surface of the connecting plate 21. The bottom of the electric push rod 11 is fixedly connected to the fixed seat 1 by screws. A control switch is provided on the outer wall of the electric push rod 11, and the control switch is electrically connected to an external power source through a wire. The end of the telescopic arm of the electric push rod 11 is fixedly connected to the bottom of the connecting plate 21 by screws. The connecting plate 21 is welded and fixed to the corresponding sleeves 20.
[0027] In this utility model, when the control switch is activated, the telescopic arm of the electric push rod 11 is extended or shortened. When the telescopic arm is extended, the positioning platform 2 moves upward, increasing the distance between the positioning platform 2 and the fixed seat 1. When the telescopic arm is shortened, the positioning platform 2 moves downward, decreasing the distance between the positioning platform 2 and the fixed seat 1. The connecting plate 21 provides a point of force, facilitating the installation of the telescopic arm of the electric push rod 11.
[0028] It should be noted that a dual-axis motor 4 is provided at the center of the lower surface of the positioning table 2. The right output shaft of the dual-axis motor 4 is provided with a forward lead screw 40, and the left output shaft of the dual-axis motor 4 is provided with a reverse lead screw 41. The dual-axis motor 4 is fixedly connected to the positioning table 2 by screws. The forward lead screw 40 and the reverse lead screw 41 are respectively welded and fixed to the corresponding output shaft of the dual-axis motor 4. The forward lead screw 40 and the reverse lead screw 41 are also threadedly connected to the screw hole 310 on the corresponding cross slide plate 31.
[0029] In this invention, the control switch on the outer wall of the dual-axis motor 4 is electrically connected to an external power source via a wire. When the control switch is activated, the output shaft of the dual-axis motor 4 rotates. When the output shaft rotates synchronously in the forward direction, the forward lead screw 40 and the reverse lead screw 41 rotate synchronously in the forward direction, causing the two cross slide plates 31 to move outward synchronously. When the output shaft rotates synchronously in the reverse direction, the forward lead screw 40 and the reverse lead screw 41 rotate synchronously in the reverse direction, causing the two cross slide plates 31 to move inward synchronously. This helps the two positioning plates 3 to move synchronously towards each other, clamping and positioning the rubber rollers 5 of different lengths, preventing the rubber rollers 5 from moving left and right when rotating. Furthermore, when clamping and positioning, the opposing sides of the two positioning plates 3 are close to the outer wall of the rubber rollers 5 with a small gap between them, which does not hinder the flexible rotation of the rubber rollers 5.
[0030] Furthermore, positioning structures for clamping and positioning the rubber rollers are provided on both ends of the positioning platform 2. Secondly, the positioning structure includes two symmetrical positioning plates 3. Each positioning plate 3 has a rotating shaft groove 30 at the top center and a cross slide plate 31 at the bottom. Each cross slide plate 31 has a screw hole 310. A cross groove 22 is provided at the end of the positioning platform 2 corresponding to the cross slide plate 31. The cross slide plate 31 and the positioning plate 3 are integrally formed. The width of the outer wall of the cross slide plate 31 is adapted to the width of the inner wall of the cross groove 22.
[0031] In this invention, the cross slide plate 31 and the cross slide groove 22 are inserted and matched, which helps the positioning plate 3 to move horizontally and stably on the positioning platform 2.
[0032] In addition, a rubber roller 5 is provided between the two rotating shaft grooves 30. The rotating shafts at both ends of the rubber roller 5 are correspondingly inserted into the rotating shaft grooves 30, and the outer diameter of the rotating shaft is adapted to the inner diameter of the rotating shaft groove 30. The end of the rotating shaft is inserted into the external driving component through a snap-fit groove and a snap-fit block.
[0033] In this invention, the rotating shaft groove 30 facilitates the insertion and engagement of the rotating shaft of the rubber roller 5, and the ends of the rotating shaft all pass through the rotating shaft groove 30. One end of the rotating shaft is inserted and engaged with an external driving component to perform the corresponding rotation engagement of the rubber roller 5, which facilitates the material conveying and guiding.
[0034] In this embodiment, when the rubber roller positioning device is in use, the positioning platform 2 is first inserted into the insertion post 10 on the fixed base 1 through the sleeve post 20. The dual-axis motor 4 with the forward lead screw 40 and the reverse lead screw 41 is fixed at the bottom of the positioning platform 2. The two positioning plates 3 are inserted into the cross slide groove 22 through the cross slide plate 31, and the screw hole 310 on the cross slide plate 31 is threadedly connected to the corresponding forward lead screw 40 and reverse lead screw 41. The fixed base 1 is placed on the bottom panel of the conveying equipment and fixed to the bottom panel by external screws passing through the fixing holes on the support foot 12. The rotating shafts at both ends of the rubber roller 5 that need to be positioned are sequentially inserted into the rotating shaft grooves 30 on the corresponding positioning plate 3, and the ends of the rotating shafts extend out from the rotating shaft grooves 30. According to the length of different rubber rollers 5, the control switch on the outer wall of the dual-axis motor 4 is activated to control the output shaft to rotate. When the output shaft rotates synchronously in the forward direction, the forward lead screw 40 and the reverse lead screw 41 rotate synchronously in the forward direction, so that the two cross slide plates 31 move outward synchronously. When the output shaft rotates synchronously in the reverse direction, the forward lead screw 40 and the reverse lead screw 41 rotate synchronously in the reverse direction, so that the two cross slide plates 31 move inward synchronously. This helps the two positioning plates 3 to move synchronously towards each other, clamping and positioning the rubber rollers 5 of different lengths. The outer wall of the rubber roller 5 is close to the side of the positioning plate 3, but not in contact with it, so as not to affect the rotation. Based on the position of the shaft and the external drive component, the control switch on the outer wall of the electric push rod 11 is activated. When the telescopic arm extends, the positioning platform 2 moves upward, increasing the distance between the positioning platform 2 and the fixed seat 1. When the telescopic arm shortens, the positioning platform 2 moves downward, decreasing the distance between the positioning platform 2 and the fixed seat 1. This allows the shaft of the rubber roller 5 to be snapped into place with the external drive component, making the overall assembly and installation convenient. It also prevents the rubber roller 5 from moving left and right when rotating, thus limiting the position of the rubber roller 5 during rotation and reducing left and right sliding. This prevents uneven force distribution when the rubber roller 5 conveys materials, which can shorten the service life of the rubber roller 5.
