Description

TECHNICAL FIELD

[0001] The application relates to the technical field of aluminum rollers, in particular to an aluminum roller with improved counterweight. BACKGROUND

[0002] In modern industrial production, aluminum rollers play an important role in material conveying, processing and manufacturing. The aluminum roller comprises a roller body and a plug head arranged on both sides of the roller body, and the roller body is of an aluminum structure. When the weight of the roller body is uneven due to production errors, the roller body is prone to deformation in a long time of work, thereby affecting the service life of the aluminum roller.

[0003] At present, when the weight of the roller body is uneven, workers usually fix counterweight nails on the plug head to make the counterweight of the roller body uniform. Specifically, workers open pre-punching holes in the plug head according to the weight distribution of the roller body, and then workers bury counterweight nails in the pre-punching holes. The counterweight nails are in interference fit with the pre-punching holes, and the counterweight of the aluminum roller is uniform under the action of the counterweight nails, thereby increasing the service life of the aluminum roller.

[0004] When the plug head is not arranged at both ends of the aluminum roller, the counterweight nails cannot be buried in the roller body, so that the counterweight of the aluminum roller cannot be changed, and there is room for improvement. CONTENT OF THE INVENTION

[0005] In order to change the counterweight of the aluminum roller when the plug head is not arranged at both ends of the aluminum roller, the application provides an aluminum roller with improved counterweight.

[0006] The application provides an aluminum roller with improved counterweight, which adopts the following technical scheme:

[0007] The aluminum roller with improved counterweight comprises a roller body, a middle shaft groove is opened in the roller body, two openings of the middle shaft groove are arranged at both ends of the roller body, a counterweight block is installed in the roller body, the counterweight block is used for balancing the weight of the roller body, an adhesive member is bonded to the inner wall of the roller body, and the counterweight block is fixed to the inner wall of the roller body through the adhesive member.

[0008] By adopting the above technical scheme, the weight distribution of the roller body can be accurately adjusted by installing the counterweight block in the roller body, so that the roller body can maintain good dynamic balance under different working conditions. The counterweight block is bonded to the inner wall of the roller body through the adhesive member, which reduces the possibility of affecting the inner wall of the roller body by the counterweight block, and the process is easier to operate. The setting realizes the change of the counterweight of the aluminum roller when the plug head is not arranged at both ends of the aluminum roller.

[0009] Optionally, the adhesive member completely covers the surface of the counterweight block, and the counterweight block is close to the opening position of the middle shaft groove.

[0010] Through the adoption of the above technical scheme, under the action of the bonding member, the counterweight block is stably fixed to the inner wall of the roller body, and the covering arrangement reduces the possibility of the counterweight block shaking when the roller body rotates, thereby increasing the stability of the roller body during operation.

[0011] Optionally, the rotating shaft is arranged in the middle shaft groove, and a plurality of bearings are fixed to the rotating shaft, and the outer rings of the bearings are in interference fit with the middle shaft groove, the rotating shaft is used for transporting the bonding member, and the rotating shaft can press the bonding member.

[0012] Through the adoption of the above technical scheme, the design of the rotating shaft makes the installation process of the bonding member more efficient, the bonding member is sent into the middle shaft groove through the rotating shaft, and the position of the bonding member is accurately controlled, so that the assembly time can be greatly shortened, and the rotating shaft can also enhance the bonding effect of the bonding member through the pressing action when transporting the bonding member.

[0013] Optionally, the rotating shaft comprises a rotating shell in interference fit with the inner rings of the bearings, a connecting rod in sliding connection with the rotating shell, and a transport rod in rotating connection with one end of the connecting rod away from the rotating shell, the transport rod is hollow, and one end of the transport rod close to the connecting rod can abut against the inner wall of the middle shaft groove.

[0014] Through the adoption of the above technical scheme, the interference fit between the rotating shell and the inner rings of the bearings ensures the stability of the rotating shaft, so that the rotating shaft can rotate smoothly in the middle shaft groove, and the hollow structure of the transport rod not only reduces the overall weight of the rotating shaft, but also facilitates the delivery of the bonding agent or other necessary substances through the inside of the transport rod, which facilitates the work of the staff in bonding the counterweight block and improves the bonding efficiency.

[0015] Optionally, the two ends of the rotating shell are both in sliding connection with the connecting rods, and one end of each of the two connecting rods away from the rotating shell is hinged with the transport rod.

[0016] Through the adoption of the above technical scheme, the design that the two ends of the rotating shell are both in sliding connection with the connecting rods makes the whole rotating shaft structure more stable, and the setting that the positions close to the two ends of the roller body can both bond the counterweight block makes the range of the counterweight larger, which is convenient for the staff to operate.

[0017] Optionally, the inner wall of the rotating shell is provided with a plurality of clamping grooves, and the end of the connecting rod is fixed with a clamping block, and the clamping block can be clamped with the clamping grooves.

[0018] Through the adoption of the above technical scheme, the clamping and clamping design of the clamping grooves and the clamping block provides a stable connection point between the rotating shell and the connecting rod, which not only enhances the stability of the whole rotating shaft structure, but also ensures that the connecting rod will not accidentally fall off or loosen during sliding, thereby improving the reliability of the connection.

[0019] Optionally, an inner part of the roller body is provided with a clamping groove for limiting the bearing.

[0020] By using the above technical scheme, the clamping groove provides a stable support and limiting point for the bearing. When the bearing is correctly installed in the clamping groove, it effectively prevents the bearing from shaking or mispositioning inside the roller body, thereby enhancing the stability of the entire roller body structure.

[0021] Optionally, a soft shell is fixed to one end of the transport rod close to the rotating shell, and the soft shell can abut against the inner wall of the roller body.

[0022] By using the above technical scheme, the soft shell is mainly provided to protect the inner wall of the roller body from damage. When the transport rod is transported or compacted, the soft shell acts as a buffer layer to reduce the friction and impact of the transport rod on the inner wall of the roller body, thereby prolonging the service life of the roller body.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When the weight distribution of the roller body is uneven, the worker places the counterweight at the part of the roller body with lighter weight according to the weight distribution of the roller body. At this time, the counterweight is placed inside the roller body, and the counterweight abuts against the inner wall of the central shaft groove. Then the worker uses an adhesive to bond the counterweight to the inside of the roller body, so that the counterweight is fixed to the inner wall of the roller body. This arrangement changes the counterweight of the aluminum roller when there is no plug at both ends of the aluminum roller.

[0025] 2. By setting the limiting structures such as the clamping groove, the clamping block and the clamping groove, the accurate assembly and positioning of the bearing and the connecting rod are achieved. BRIEF DESCRIPTION OF DRAWINGS
