[0002] The roller body is a cylindrical part, and the roller body is mainly divided into a driving roller and a driven roller. Rollers are widely used in various transmission and conveying systems such as rotary screen printing machines, digital printers, mining conveying equipment, papermaking and packaging machinery. When the roller body is subjected to force or non-uniform temperature changes, the axis of the roller body will be displaced in a direction perpendicular to its axis, that is, a certain deflection will occur. If the deflection of the roller body is large, the roller body will be unbalanced when it rotates, and even cause the roller body to shake. Therefore, a roller body deflection balancing device is needed to balance the deflection of the roller body. However, the existing deflection balancing device for the roller body generally adds a balancing block to the outside of the roller body, which will change the external shape of the roller body and affect the normal use of the roller body to a certain extent.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In the description of the embodiments of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limitations on the present invention. The terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to the specific circumstances.

[0036] like Figures 1 to 4 As shown, the deflection balancing device for a roller body provided in an embodiment of the present invention includes a mounting shell 1, a support assembly 2, and a counterweight block 3.

[0037] The installation housing 1 is a cubic structure with one end open, and a clamping ring 11 is provided on the bottom surface of the installation housing 1. A plug hole 12 is provided on the end surface of the opening end of the installation housing 1, and the clamping ring 11 and the plug hole 12 are coaxially arranged.

[0038] The number of the support assemblies 2 is four, and the four support assemblies 2 are evenly distributed in the circumference of the mounting housing 1. The support assemblies 2 include a screw rod 4, an abutment plate 5, and an adjustment gear 6.

[0039] The adjusting gear 6 includes a driven bevel gear 61 and a rotating inner ring 62 fixed to one side of the driven bevel gear 61 . The rotating inner ring 62 is engaged in a fixed ring 13 on the side wall of the mounting housing 1 . The rotating inner ring 62 and the fixed ring 13 are rotationally connected.

[0040] One end of the screw rod 4 is screwed into the threaded hole in the adjusting gear 6 and then rotatably connected to the abutment plate 5. The counterweight block 3 is mounted on the abutment plate 5 of one of the supporting assemblies 2.

[0041] It should be noted that the mounting shell 1 is a square shell with one end open, and the mounting shell 1 is used to mount the support assembly 2 and the counterweight 3. The mounting shell 1 can also adopt a column structure with one end open. The number of support assemblies 2 is three or more, and the deflection balance purpose of the present invention can be achieved. The four groups of support assemblies 2 of the present invention have higher stability and are easy to install.

[0042] The clamping ring 11 is used to cooperate with the mounting mechanism of the balancing device to realize the rotation of the adjusting gear 6. After the jack 12 is installed in cooperation with the mounting mechanism of the balancing device, the mounting housing 1 can be relatively fixed to ensure that the adjusting gear 6 can rotate normally.

[0043] The four groups of support assemblies 2 are respectively arranged on the four sides of the mounting housing 1, and the axes of the screws 4 of the four groups of support assemblies 2 are located in the same plane. The rotating inner ring 62 and the fixed ring 13 can be connected through a bearing or directly in a set connection mode, which has a lower cost.

[0044] When the adjusting gear 6 rotates on the fixing ring 13 , it can drive the screw rod 4 to move along its axial direction, so that the abutting plate 5 can move toward the outside of the mounting housing 1 through the screw rod 4 .

[0045] The counterweight block 3 is used to balance the deflection of the roller body 10 during rotation. The counterweight block 3 can be made of a metal block, such as a stainless steel block. The counterweight block 3 is clamped on the end of the screw rod 4. After the screw rod 4 and the abutment plate 5 are connected, the counterweight block 3 can be fixedly installed between the screw rod 4 and the abutment plate 5.

[0046] The balancing device of the present invention is installed in the roller body 10. When the roller body 10 rotates, the counterweight 3 applies an outward force to the roller body 10 under the action of its centripetal force, thereby keeping the roller body 10 balanced when rotating. The present invention adds a balancing device inside the roller body 10, so the external shape of the roller body 10 is not changed, thereby avoiding the problem of adding a balancing block outside the roller body 10, which affects the normal use of the roller body 10.

[0047] like Figure 1 and Figure 2 As shown, in this embodiment, an anti-loosening mechanism is also included on the side wall of the mounting shell 1 , and the anti-loosening mechanism includes a top column 7 , a spring 8 , and a limit pin 9 .

[0048] The side wall of the mounting housing 1 is provided with an anti-loosening hole 14 , the anti-loosening hole 14 passes through the fixing ring 13 , the top column 7 is located in the anti-loosening hole 14 , and the axis of the top column 7 and the anti-loosening hole 14 is perpendicular to the screw rod 4 .

[0049] The spring 8 is arranged between the rear end of the top column 7 and the bottom of the anti-loosening hole 14, one end of the limit pin 9 penetrates into the anti-loosening hole 14 from the inner wall of the mounting shell 1, the axis of the limit pin 9 and the anti-loosening hole 14 are perpendicular, the limit pin 9 and the front end surface of the top column 7 are abutted, and a first pull ring is arranged at the rear end of the limit pin 9.

[0050] It should be noted that before the balancing device is installed, the anti-loosening mechanism is in the initial state, that is, the limit pin 9 is in contact with the front end surface of the top column 7, and the spring 8 is in a compressed state. When the balancing device is installed in place, the limit pin 9 is pulled out from the side wall of the installation shell 1 by pulling the first pull ring, and the top column 7 moves toward the direction of the screw 4 under the action of the spring 8, and finally the top column 7 is in contact with the side wall of the screw 4, and there is a certain friction between the end of the top column 7 and the screw 4, so that the screw 4 and the adjustment gear 6 can be prevented from rotating relative to each other. Therefore, after the balancing device of the present invention is installed in the roller body 10, the balancing device has higher stability and is not easy to loosen.

[0051] like Figure 3 and Figure 4As shown, the embodiment of the present invention further provides a mounting mechanism for a deflection balancing device, which is used to mount the above-mentioned deflection balancing device for a roller body inside the roller body 10. The mounting mechanism for the deflection balancing device includes a fixed cylinder 20, a core shaft 21 disposed in the fixed cylinder 20, an active bevel gear 22, a positioning shaft 23, and an insertion rod 24.

[0052] The core shaft 21 and the fixed cylinder 20 are rotationally connected. The front end of the core shaft 21 extends out of the fixed cylinder 20 and is connected to the rear end of the active bevel gear 22. The positioning shaft 23 is rotationally connected to the front end of the active bevel gear 22. The axes of the positioning shaft 23, the active bevel gear 22, and the core shaft 21 coincide.

[0053] The insertion rod 24 is mounted on the side wall of the fixed cylinder 20 via a connecting rod, and the axes of the insertion rod 24 and the core shaft 21 are parallel.

[0054] It should be noted that the mandrel 21 and the fixed cylinder 20 can be connected in rotation by bearings, and the two ends of the mandrel 21 extend out of the two ends of the fixed cylinder 20. The mandrel 21 and the fixed cylinder 20 can rotate relative to each other, so after the position of the fixed cylinder 20 is fixed, the rotating mandrel 21 can rotate the active bevel gear 22. The rear end of the rotating mandrel 21 can be installed with a rotating force component, such as a rotating handle or other structures.

[0055] After the insertion rod 24 is inserted into the insertion hole 12, the end of the positioning shaft 23 is inserted into the clamping ring 11, and the active bevel gear 22 is meshed with the driven bevel gears 61 of the four groups of support assemblies 2, the active bevel gear 22 can be driven to rotate by rotating the core shaft 21, and then the driven bevel gear 61 can be rotated, thereby achieving the purpose of driving the screw 4 to rotate.

[0056] In this embodiment, a second pull ring is provided at the front end of the fixed cylinder 20 .

[0057] It should be noted that the second pull ring is used to cooperate with the first pull ring. After the mounting mechanism for the deflection balancing device and the deflection balancing device for the roller body are assembled, the second pull ring is connected to the first pull ring through a rope.

[0058] like Figures 1 to 4 As shown, an embodiment of the present invention further provides a method for installing a deflection balancing device for a roller body, the method is an operation step of installing the balancing device in the roller body 10 through the installation mechanism of the balancing device, and the method specifically includes the following steps:

[0059] Step 1: remove the shaft head at one end of the roller body 10, and then fix and install the roller body 10. The present invention is applicable to a roller body 10 with a hollow structure inside the roller body 10, and a balancing device is added inside the roller body 10 to achieve a balanced state when the roller body 10 rotates.

[0060] Step 2: Measure the deflection of the roller body 10 to determine the weight and installation position of the counterweight 3. After the balancing device is installed in place, measure the deflection of the roller body 10 again to ensure that the deflection of the roller body 10 is corrected.

[0061] Step three: install the counterweight 3 onto the abutment plate 5 of one of the support assemblies 2 .

[0062] A rubber pad can be arranged between the abutment plate 5 and the inner wall of the roller body 10, which can prevent the abutment plate 5 from scratching the inner wall of the roller body 10. After the rubber pad is compressed, it plays a role similar to that of a spring 8 washer, thereby preventing the screw 4 from loosening easily.

[0063] Assemble the mounting mechanism for the deflection balancing device and the deflection balancing device for the roller body, insert the insertion rod 24 into the insertion hole 12, insert the end of the positioning shaft 23 into the clamping ring 11, and make the active bevel gear 22 mesh with the driven bevel gears 61 of the four groups of support assemblies 2.

[0064] In order to prevent the insertion rod 24 from falling out of the insertion hole 12, a locking mechanism can be used on the insertion rod 24, and the locking mechanism can be a stepper motor installed in the insertion rod 24. A clamping piece is provided on the output shaft of the stepper motor, and the clamping piece can be clamped in the groove body of the inner wall of the insertion hole 12 by rotating the clamping piece, so that the insertion rod 24 and the insertion hole 12 are relatively fixed, and the control end of the stepper motor can be set at the rear end of the fixed cylinder 20. Rotating the clamping piece again can remove the clamping piece from the groove body, and the insertion rod 24 and the insertion hole 12 can be separated at this time.

[0065] The locking mechanism may also adopt a relatively simple structure, for example, the following structure: after the end of the insertion rod 24 is inserted into the insertion hole 12, the fixed cylinder 20 is rotated so that the protrusion at the end of the insertion rod 24 is engaged in the groove on one side of the bottom of the insertion hole 12 to prevent the insertion rod 24 from moving along its axial direction, wherein the rotation direction of the fixed cylinder 20 is opposite to the rotation direction when the core shaft 21 drives the active bevel gear 22, thereby avoiding the problem that the protrusion at the end of the insertion rod 24 moves out of the groove when the core shaft 21 rotates.

[0066] In this embodiment, step three also includes the following steps: connecting the first pull ring and the second pull ring through a pull rope.

[0067] Step 4: Use the fixed cylinder 20 to push the deflection balancing device for the roller body to the set position in the roller body 10, and then fix the fixed cylinder 20 by the fixing device.

[0068] Step five, rotating the core shaft 21 , the core shaft 21 drives the active bevel gear 22 to rotate, the active bevel gear 22 drives the driven bevel gear 61 to rotate, and then the screw 4 drives the abutment plate 5 to approach the inner wall of the roller body 10 under the action of the adjusting gear 6 .

[0069] Step six, after the abutment plate 5 abuts against the inner wall of the roller body 10 , the mounting mechanism for the deflection balancing device is pulled outwards, so that the insertion rod 24 is withdrawn from the insertion hole 12 , and the end of the positioning shaft 23 is withdrawn from the clamping ring 11 .

[0070] In this embodiment, step six also includes the following steps: the fixed cylinder 20 drives the first pull ring to move through the pull rope, the first pull ring pulls the limit pin 9 out from the inner wall of the mounting shell 1, and the top column 7 moves toward the direction of the screw 4 under the action of the spring 8, thereby making the end of the top column 7 abut against the side wall of the screw 4.

[0071] Then the shaft head of the roller body 10 is installed, thereby completing the installation of the balancing device.

[0072] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0073] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment based on the technical essence of the present invention still falls within the protection scope of the technical solution of the present invention.
