Description

Technical Field

[0001] This utility model relates to the field of turntable support technology, specifically a turntable support device. Background Technology

[0002] The rotary two-color printing press has a cantilever beam structure for supporting the mold. After supporting the mold, it will inevitably generate a lateral tilting moment. Especially when supporting heavy weight and high torque molds, the rotary table will tilt, causing wear and jamming between the rotary table and the template surface. At the same time, it will cause deviations in the parallelism and coaxiality of the male and female molds, affecting product production and precision.

[0003] In the prior art, application number 202322478460.2 is disclosed, entitled "A Rotary Support Device for a Multi-Material Injection Molding Machine", which includes a support base, an integral support and roller integrals. The integral support is vertically installed on the right side of the upper end face of the support base, and a plurality of roller integrals are evenly installed on the right side of the integral support.

[0004] In existing technology, the rollers are fixedly connected to the overall support and installed on the support as an external structure. This is cumbersome to install and lacks adjustment function for supporting the turntable, resulting in the rollers not being able to fit tightly with the turntable when lifting the box. Therefore, a turntable support device needs to be designed. Utility Model Content

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] A turntable support device, such as Figures 1-4As shown, the turntable support device is symmetrically installed on the moving mold 1 to support the turntable 2 on the moving mold 1. The turntable support device can bear the lateral tilting force of the turntable 2, improve the load-bearing capacity of the turntable 2, improve the parallelism and coaxiality of the turntable 2 and the mold on it with the fixed mold, and ensure the stability of the turntable 2.

[0026] The turntable support device includes an installation groove 11 formed on the moving mold 1. The installation groove 11 is symmetrically arranged on the moving mold 1. A fixing block 12 is provided on the installation groove 11. The fixing block 12 is fixedly installed on the moving mold 1 by bolts. An adjusting screw 14 is threadedly connected to the fixing block 12. One end of the adjusting screw 14 is fixedly connected to a nut 15, and the other end is attached to the support column 31. The support column 31 is supported and fixed by the adjusting screw 14.

[0027] In this embodiment, a locking screw 13 is threaded onto the fixing block 12. The locking screw 13 is added to lock the position of the support column 31, preventing the support column 31 from loosening and also preventing the device from being tilted by the turntable 2.

[0028] A support column 31 is slidably installed in the mounting groove 11. One end of the support column 31 is rotatably connected to a support bearing 3, and the other end is fixedly connected to a slider 32. The slider 32 is slidably connected to the mounting groove 11, and a limit hole 33 is opened on the support column 31. The limit hole 33 is connected to the locking screw 13, and the side of the support column 31 is attached to the adjusting screw 14.

[0029] In this embodiment, a bearing outer sleeve 30 is fixedly installed on the support bearing 3. Whether or not to install the bearing outer sleeve 30 is selected according to actual production needs.

[0030] In this embodiment, the support bearing 3 is selected from deep groove ball bearings, roller bearings or support bearings (i.e. roller bearings and mounting shaft integrated bearings). The outer ring of the bearing can be fitted with a bearing outer sleeve 30 to increase the radial load capacity. The bearing is in line contact with the turntable 2, supports the turntable 2 and rotates with the turntable 2.

[0031] The fixing block 12 is fixedly connected to the template. In this embodiment, it is fixed from the side, but it can also be fixed from the bottom. Its function is to be integrated with the template and to bear the force.

[0032] The working principle is as follows:

[0033] One end of the support column 31 is installed with the support bearing 3, and the other side is embedded in the moving mold 1. The T-slot on the template allows the support column to slide up and down in the slot. The gap between the upper and lower surfaces of the T-slot and the corresponding surfaces of the support column is small, ensuring that the lateral tilting force of the support column 31 is borne by the moving mold 1.

[0034] The adjusting screw 14 on the fixed block 12 supports the support column 31, ensuring that the support bearing 3 on the support column 31 supports the turntable. After adjustment, the position is locked by the nut 15. After adjusting the position, the adjusting screw 14 is tightened to lock it. The whole device is integrated and is not easily tilted by the radial force transmitted by the turntable 2.

[0035] This device can withstand the lateral tilting force of the turntable 2, thereby improving the load-bearing capacity of the turntable 2. At the same time, its symmetrical arrangement can adjust and improve the parallelism and coaxiality between the turntable 2 and the fixed mold.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
