The outer edge of each multi-layer roller sheet is rotationally connected with a licker-in ring through a bearing; a plurality of notches distributed in a staggered mode are further formed in the square shaft, jacking columns are arranged in the notches, the jacking columns ascend and descend through air cylinders, and the air cylinders are communicated with an air connecting valve through a pipeline; limiting rings are arranged at the two ends of each multi-layer roller piece, each limiting ring is composed of two semi-circular rings, and fixing holes are formed in the semi-circular rings.

Description

Technical Field

[0001] The utility model belongs to the technical field of tire manufacturing, and particularly relates to a thousand-layer thistle roll. Background Art

[0002] At present, there are two forms of pressing the tread joint of a semi-steel forming machine. One is that the operator manually rolls the tread joint with a thistle roll. This method is time-consuming and laborious, with low efficiency and uneven joints and poor quality. The second is to roll the tread joint with a plastic thousand-layer roll. Although the thousand-layer roll can achieve the overall pressing of the tread joint (the middle of the tread, the shoulder, and the small sidewall of the tire), the pressing effect on the tread with poor adhesion is not good, and the tread joint with poor adhesion cannot be effectively pressed, resulting in the generation of defective products with cracks at the tread joint after vulcanization. Content of the Utility Model

[0003] The purpose of the utility model is to solve the above technical deficiencies and provide a thousand-layer thistle roll.

[0004] To this end, the utility model provides a thousand-layer thistle roll, which includes a square shaft. A plurality of thousand-layer roll sheets are sleeved on the square shaft. Each thousand-layer roll sheet is provided with a direction groove matching the shape of the square shaft, so that the thousand-layer roll sheet slides up and down along the square shaft; the outer edge of each thousand-layer roll sheet is rotatably connected with a thistle roll ring through a bearing; a plurality of staggered slot openings are also provided on the square shaft, and a jacking column is arranged in the slot opening. The jacking column is lifted and lowered by a cylinder, and the cylinder is connected to an air intake valve through a pipeline.

[0005] Further, limit rings are arranged at both ends of the thousand-layer roll sheet. The limit ring is composed of two semi-circular rings, and fixing holes are provided on the semi-circular rings, and the limit ring can be fixed on the square shaft through bolts.

[0006] Further, a total of six air intake valves are provided, and each air intake valve controls a plurality of jacking columns in one area of the thousand-layer thistle roll.

[0007] The utility model provides a thousand-layer thistle roll, which has the following beneficial effects:

[0008] 1. The tread thistle roll can press the middle part of the tread, the shoulder, and the small sidewall of the tire, and the tread joint is pressed flat.

[0009] 2. The pressing effect of the tread thistle roll on the tread joint with poor adhesion is better than that of the thousand-layer roll.

[0010] 3. The tread thistle roll can achieve segmented control of pressure and can be adjusted according to requirements.

[0011] 4. Adding a thousand-layer thistle roll to the tread can effectively improve the quality of the tread joint and reduce the generation of defective products with cracks at the tread joint. Description of the Drawings

[0018] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present utility model. The methods used in the present utility model are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercially available products unless otherwise specified.

[0019] As Figure 1 , shown in FIGS. 2 and 4, the present utility model provides a multi-layer thistle roller, which includes a square shaft 1. A plurality of multi-layer roller sheets 2 are sleeved on the square shaft 1. Each multi-layer roller sheet 2 is provided with a square groove 3 that matches the shape of the square shaft 1, which can enable the multi-layer roller sheet 2 to slide up and down along the square shaft 1. A thistle roller ring 4 is rotatably connected to the outer edge of each multi-layer roller sheet 2 through a bearing. The square shaft 1 is also provided with a plurality of staggered slots, and a jacking column 6 is arranged in the slots. The jacking column 6 is lifted and lowered by a cylinder, and the cylinder is connected to the air intake valve 7 through a pipeline. Through the staggered jacking columns 6, it can be ensured that when a plurality of multi-layer roller sheets 2 are lifted, the force is more uniform, providing a stable pressing pressure and making the pressing effect of the tread 9 better.

[0020] As Figure 34, when in use, the plural-layer licker-in roller is installed on the forming machine, and the forming machine fits the plural-layer licker-in roller with the tread 9 on the bonding drum 10, and the tread 9 pushes the corresponding plural-layer roller sheet 2 upward and staggers with other plural-layer roller sheets 2. At this time, the multiple lifting columns 6 corresponding to the plural-layer roller sheet 2 that is pushed up are raised to apply downward pressure to the plural-layer roller sheet 2. Then the bonding drum 10 drives the tread 9 to rotate, and the plural-layer roller sheet 2 that is pushed up is rolled and pressed on the middle part, shoulder and small side of the tread 9. At the joint position of the tread 9, the multiple lifting columns 6 corresponding to the plural-layer roller sheet 2 that is pushed up further increase the lifting height, so that the plural-layer roller sheet 2 that is pushed up can provide greater pressing pressure. Then the bonding drum 10 drives the tread 9 to reciprocate, so that the joint position of the tread 9 can be repeatedly rolled, and the joint of the tread 9 is pressed and flat.

[0021] Limiting rings 5 ​​are provided at both ends of the melaleuca roller 2. The limiting rings 5 ​​are composed of two semicircular rings. Fixing holes 8 are opened on the semicircular rings. The limiting rings 5 ​​can be fixed on the square shaft 1 by bolts, thereby fixing the width of the melaleuca roller 2.

[0022] like Figure 5 As shown, the centerline position of the pushed-open plural roller sheet 2 is used as the first reference, and the plural roller is divided into two left and right areas. The left and right sides of the plural roller are both plural roller sheets 2 that have not been pushed open and plural roller sheets 2 that have been pushed open; the centerline position of the plural roller sheet 2 that has not been pushed open is used as the second reference, and the plural roller sheet 2 that has not been pushed open is further divided into two left and right areas, and the plural roller is divided into six areas in total. There are six air receiving valves 7 in total, and each air receiving valve 7 controls multiple lifting columns 6 in one area of ​​the plural roller, so that the pressure of each area of ​​the plural roller can be adjusted. Moreover, through the above design, the control method can be flexibly adjusted according to the actual width of the tread 9, which has good versatility.

[0023] In the description of the present invention, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inside", "outside", "back", "middle", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] However, what is described above is only a specific embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the patent of the present invention should still fall within the scope covered by the claims of the present invention.
