Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, a system for producing a tire inner liner according to the present invention will be described in further detail with reference to the accompanying drawings and examples.

For ease of understanding, the structure of the lining layer will first be described, as shown in fig. 1, the lining layer includes a transition layer 11 and an airtight layer 12, which are bonded together by a vulcanization process or the like.
As shown in fig. 2, a production system for a tire inner liner includes: transition layer production unit 2, inner liner production unit 3, conveyor 4, separation platform 5 and support 51. The support column 51 is vertically arranged, the bottom end of the support column is fixed on the ground, the separation platform 5 is horizontally arranged, and the support column is fixedly connected to the top end of the support column 51, so that an accommodating space 52 is formed between the separation platform 5 and the ground, the transition layer production unit 2 is arranged on the upper surface of the separation platform 5, and the air barrier production unit 3 is arranged in the accommodating space 52. The transition layer production unit 2 and the airtight layer production unit 3 both correspond to the conveying device 4, so that the transition layer 11 produced by the transition layer production unit 2 and the airtight layer 12 produced by the airtight layer production unit 3 can be overlapped on the conveying device 4 from top to bottom, and the conveying device 4 can drive the overlapped transition layer 11 and the overlapped airtight layer 12 to move so as to convey the overlapped transition layer 11 and the overlapped airtight layer 12 into a pre-vulcanizing device through the conveying device 4 for pre-vulcanizing. Adopt such technical scheme, can produce transition layer 11 and airtight layer 12 simultaneously, improve production efficiency, through the mode that adopts transition layer production unit 2 and airtight layer production unit 3 to arrange from top to bottom, realize the miniaturized design of production line simultaneously, reduced area, and then avoid causing the soil extravagant.
As an embodiment, as shown in fig. 2, 3, 4 and 5, the transition layer production unit 2 includes a first driving device 21 and a first rolling device 22 for pressing the process profile on the surface of the transition layer 11. As shown in fig. 5, the first rolling device 22 includes a first frame 221, a first pressing roller 222 and a second pressing roller 223, the first frame 221 is fixedly disposed on the separation platform 5, the first pressing roller 222 includes a first rotating shaft 224 and a first roller sleeve 225 disposed on the first rotating shaft 224, the second pressing roller 223 includes a second rotating shaft 226 and a second roller sleeve 227 disposed on the second rotating shaft 226, and both the first rotating shaft 224 and the second rotating shaft 226 are rotatably connected to the first frame 221 and have parallel axes. In actual use, the transition layer 11 can pass between the first pressing roller 222 and the second pressing roller 223, and the first roller sleeve 225 and the second roller sleeve 227 rotate relatively to press the process profile on the surface of the transition layer 11, which is a relatively mature technology in the field and is not the invention point of the invention, so that the specific installation mode and the rotation operation principle of the first pressing roller 222 and the second pressing roller 223 are not described in detail here.
Since the first roll shell 225 and the second roll shell 227 need to be replaced frequently in order to meet the needs of the work in the actual work, the first roll shell 225 and the second roll shell 227 are inconvenient to replace due to the heavy weight of the first roll shell 225 and the second roll shell 227. Therefore, as shown in fig. 5, the first driving device 21 is fixedly disposed on the partition platform 5, and the first driving device 21 can be connected to the first roller housing 225 and can drive the first roller housing 225 to perform a linear reciprocating motion relative to the first rotating shaft 224 along the axial direction of the first rotating shaft 224, or the first driving device 21 can be connected to the second roller housing 227 and can drive the second roller housing 227 to perform a linear reciprocating motion relative to the second rotating shaft 226 along the axial direction of the second rotating shaft 226. Wherein, the first driving device 21 can be a linear driving device such as an air cylinder or an oil cylinder or an electric push rod, and is attached in use to one end of the first roll shell 225 (or the second roll shell 227) in the axial direction, meanwhile, the connection between the end of the first rotating shaft 224 (or the second rotating shaft 226) far away from the first driving device 21 and the first frame body 221 is removed, so that the end of the first rotating shaft 224 (or the second rotating shaft 226) far away from the first driving device 21 is in a free state, when the first driving means 21 drives the first sleeve 225 (or the second sleeve 227) to move away from itself, the first roll shell 225 (or the second roll shell 227) can be detached from the first rotating shaft 224 (or the second rotating shaft 226) through the end of the first rotating shaft 224 (or the second rotating shaft 226) in the free state, thereby completing the detachment work of the first roll shell 225 (or the second roll shell 227). When the first driving device 21 drives the first roller shell 225 (or the second roller shell 227) to move towards the direction close to the first roller shell 225 (or the second roller shell 227), the first roller shell 225 (or the second roller shell 227) can be sleeved on the first rotating shaft 224 (or the second rotating shaft 226) through one end of the first rotating shaft 224 (or the second rotating shaft 226) in a free state, and then the installation work of the first roller shell 225 (or the second roller shell 227) is completed. Therefore, the first roller sleeve 225 and the second roller sleeve 227 can be replaced by the first driving device 21, so that the labor intensity of operators is reduced, and the production efficiency and the safety are improved.
Further, as shown in fig. 5, the transition layer production unit 2 further includes a first fixing bracket 26, a first fixing member (not shown), and a second fixing member (not shown), the first fixing bracket 26 has a first fixing position 261 corresponding to the first roller sleeve 225 and a second fixing position 262 corresponding to the second roller sleeve 227, and the first driving device 21 is connected to the first fixing bracket 26 and can switch between the first fixing position 261 and the second fixing position 262. When the first driving device 21 is located at the first fixing position 261, the first fixing member can fix the first driving device 21 at the first fixing position 261, and when the first driving device 21 is located at the second fixing position 262, the first fixing member can fix the first driving device 21 at the second fixing position 262. The first fixing member and the second fixing member may be any members such as screws or fixing pins that can achieve the object of the invention. In actual production, the first driving device 21 has a driving shaft (not shown) that can abut on the end side of the first sleeve 225 (or the second sleeve 227). When the first drive 21 is fixed in the first fixing station 261, the axis of the drive shaft coincides with the axis of the first roller shell 225, and when the first drive 21 is fixed in the second fixing station 262, the axis of the drive shaft coincides with the axis of the second roller shell 227.
Preferably, as shown in fig. 2, 3 and 4, the lifting device 6 is further included, and as shown in fig. 4, the lifting device 6 includes a supporting frame 61, a driving device 62 and a supporting plate 63 for supporting the first roller shell 225 and/or the second roller shell 227. The supporting frame 61 is fixedly connected with the separating platform 5, and the driving device 62 is disposed on the supporting frame 61 and connected with the supporting plate 63, so that the driving device 62 can drive the supporting plate 63 to drive the first roller sleeve 225 or the second roller sleeve 227 to move to a position corresponding to the first rotating shaft 224 or the second rotating shaft 226. Therefore, the first roller sleeve 225 and/or the second roller sleeve 227 can be conveyed to the upper part of the separation platform 5 from the ground through the lifting device 6, the manual conveying mode of an operator is replaced, the labor intensity of the operator is reduced, and meanwhile, the safety is improved.

In actual manufacturing, the number of the adjusting mechanisms 251 is two or more, the two or more adjusting mechanisms 251 are sequentially arranged at intervals along the running direction of the transition layer 11, and the position of the transition layer 11 is limited along the running direction of the transition layer 11 by the two or more adjusting mechanisms 251, so that the transition layer 11 can be ensured to accurately fall on the conveying device 4, and the accuracy of the relative position between the transition layer 11 and the airtight layer is further ensured.
