Description

Technical Field

[0001] This application relates to the field of tire manufacturing technology, and in particular to an automatic rubber compound splicing device. Background Technology

[0002] In the internal mixing process of rubber tire and product factories, the parts connecting the rubber sheet cooling line may be extruded by a twin-screw extruder or a two-roll mill. Due to different rubber compound formulations and process requirements, if the rubber sheet requires one end per batch and mixing is not allowed, the rubber tail of the previous batch and the rubber head of the next batch need to be pressed together to prevent breakage, which would necessitate re-grinding and cause abnormalities. The existing solution is attached. Figure 1 As shown, an overlapping platform 10 is provided, and a pressing roller device 100 is set above the overlapping platform. Manual labor involves overlapping the rubber tail of the previous batch and the rubber head of the next batch on the overlapping platform, and then manually controlling the pressing roller device 100 to descend and press the overlapping area of ​​the head and tail together. A roller with a textured surface rolls at the overlapping point of the rubber head and tail, connecting the two batches of rubber together. This method requires manual intervention; it cannot be automated, requiring tedious manual overlapping and cylinder control operations, increasing production costs, and carries the risk of human error. Summary of the Invention

[0003] The purpose of this utility model application is to provide an automatic overlap device for rubber materials, which adopts a staggered overlap method to automatically complete the overlap and pressing operations, reduce manual intervention, lower production costs, and reduce the risks associated with manual intervention.

[0004] This application provides an automatic rubber compound end-to-end overlapping device, which includes an intermittently distributed conveying mechanism and a pressing roller device mounted at the end of the conveying mechanism. The conveying mechanism includes a primary conveying mechanism for conveying along a first direction and a secondary conveying mechanism for conveying along the first direction and / or a second direction. The first end of the secondary conveying mechanism extends obliquely below the primary conveying mechanism, and the second end of the secondary conveying mechanism is at the same conveying height as the primary conveying mechanism. The pressing roller device includes a pressing roller located at the second end of the secondary conveying mechanism and a driving component for driving the pressing roller to a first set height and a second set height. A rubber infeed control component is mounted on the secondary conveying mechanism for detecting the head and tail end position information of the rubber compound. When the rubber infeed control component receives the tail end information of the rubber compound, it controls the secondary conveying mechanism to convey the rubber compound a set distance along the second direction. When the rubber infeed control component receives information that the head end of one rubber compound covers the tail end of another rubber compound, it controls the secondary conveying mechanism to convey the rubber compound along the first direction to directly below the pressing roller, and controls the pressing roller to be at the second set height.

[0005] In this application, after receiving the tail end information of the previous rubber material through the glue supply control component, it controls the secondary conveying mechanism to convey the material in the second direction, so that the tail end of the previous rubber material is below the primary conveying mechanism. The head end of the next rubber material falls to the detection end of the secondary conveying mechanism under the conveying of the primary conveying mechanism. At this time, the tail end of the previous rubber material is covered by the head end of the next rubber material, completing the head-to-tail overlap operation between the rubber materials. The glue supply control component controls the primary and secondary conveying mechanisms to convey the material in the first direction simultaneously and move it to directly below the pressing roller device to complete the pressing operation. The overall operation process is simple and convenient, requires no manual intervention, and the pressing effect is firm and reliable.

[0006] In one specific implementation, the first direction and the second direction are two opposite directions.

[0007] In one specific implementation scheme, the secondary conveying mechanism includes: an inclined conveyor platform and a planar conveyor platform connected to the inclined conveyor platform; wherein the inclined lower end of the inclined conveyor platform extends below the primary conveying mechanism.

[0008] In one specific implementation, the glue delivery control assembly is mounted on the inclined conveyor table.

[0009] In one specific implementation, the pressing roller device is located directly above the planar conveyor.

[0010] In one specific implementation scheme, the secondary conveying mechanism conveys a set distance along the second direction such that the tail end of the rubber material is located directly below the primary conveying mechanism.

[0011] In one specific implementation, when the drive assembly drives the pressing roller to the first set height, the pressing roller avoids the planar conveyor table conveying the adhesive material.

[0012] In one specific implementation, when the glue delivery control component receives information that the head end of one glue material covers the tail end of another glue material, it controls the primary conveying mechanism and the secondary conveying mechanism to synchronously convey the glue material in the first direction.

[0017] To facilitate understanding of the automatic rubber compound end-to-end splicing device provided in this application embodiment, its application scenario is first described. The automatic rubber compound end-to-end splicing device provided in this application embodiment is applied in the field of tire manufacturing technology. Because different rubber compound formulations have different process requirements, if the rubber sheet requires one end per batch and mixing is not allowed, it is necessary to press the rubber end of the previous batch and the rubber head of the next batch together to avoid breakage, which would necessitate re-gluing the rubber and cause abnormalities. Existing solutions are attached. Figure 1 As shown, an overlapping platform 10 is provided, and a pressing roller device 100 is set above the overlapping platform. Manual labor involves overlapping the rubber tail of one cart and the rubber head of the next cart on the overlapping platform, and then manually controlling the pressing roller device 100 to descend and press the overlapping area of ​​the head and tail together. A roller with a textured surface rolls at the overlapping point of the rubber head and tail, connecting the two carts of rubber together. This method requires manual intervention; it cannot be automated, requiring tedious manual overlapping and cylinder control, increasing production costs, and posing risks associated with manual intervention. Therefore, this application provides an automatic rubber head and tail overlapping device that uses a staggered overlapping method to automatically complete the overlapping and pressing operations, reducing manual intervention, lowering production costs, and reducing the risks associated with manual intervention.

[0018] Therefore, the automatic glue joint device provided in this application uses a glue supply control component in conjunction with a secondary conveying mechanism to adjust the conveying direction and achieve glue jointing without manual intervention. The automatic glue joint device is described in detail below with specific examples.

[0019] refer to Figure 2 As shown, Figure 2A schematic diagram of the automatic rubber compound end-to-end overlapping device provided in this application is shown. This automatic rubber compound end-to-end overlapping device requires no manual intervention. By controlling the forward and reverse operation of the conveying mechanism, it achieves synchronous conveying after the tail end of the previous rubber compound overlaps with the head end of the next rubber compound. The entire process requires no manual intervention, ensuring the accuracy of the overlapping length and possessing a highly automated operation process.

[0020] The automatic rubber compound head-to-tail splicing device in this application includes an intermittently distributed conveying mechanism; the conveying mechanism comprises two conveying mechanisms, and there is an operating space between the two conveying mechanisms for splicing, thereby ensuring that the tail of the previous rubber compound and the head of the next rubber compound have space to be spliced.

[0021] Specifically, the conveying mechanism includes: a primary conveying mechanism 210 for conveying along a first direction, and a secondary conveying mechanism for conveying along the first direction and / or a second direction; the primary conveying mechanism 210 is horizontal and is mounted on the work site via a first bracket 200; after the tail end of the previous adhesive material is conveyed by the primary conveying mechanism 210, it falls to the secondary conveying mechanism, and the adhesive receiving control component 400 on the secondary conveying mechanism detects the tail end information of the previous adhesive material and controls the secondary conveying mechanism to convey along the second direction; the secondary conveying mechanism is mounted on the rear end of the primary conveying mechanism 210 via a second bracket 300.

[0022] The primary conveying mechanism 210 in this application is used for horizontal conveying of the adhesive material. The first end of the secondary conveying mechanism extends obliquely below the primary conveying mechanism 210, and the second end of the secondary conveying mechanism is at the same conveying height as the primary conveying mechanism 210. When the previous adhesive material is about to be consumed, the primary conveying mechanism 210 conveys the tail end of the previous adhesive material to the secondary conveying mechanism. As an important conveying component in this application, the secondary conveying mechanism has the flexibility to switch between forward conveying (first direction) and reverse conveying (second direction). After the adhesive receiving control component 400 on the secondary conveying mechanism detects the tail end information of the previous adhesive material, it switches the forward conveying to reverse conveying, so that the tail end of the previous adhesive material extends below the primary conveying mechanism 210. The adhesive receiving control component 400 uses a photoelectric sensor component for detection and controls the corresponding operation of the secondary conveying mechanism and the pressing roller 120 device. These are all prior art known to those skilled in the art and will not be described in detail here.

[0023] Continue reading Figure 2 The secondary conveying mechanism includes an inclined conveyor 310 and a flat conveyor 320 connected to the inclined conveyor; wherein the inclined lower end of the inclined conveyor 310 extends below the primary conveying mechanism 210. The inclined conveyor 310 and the flat conveyor 320 on the secondary conveying mechanism are an integrated conveying structure, and the glue supply control assembly 400 is mounted on the inclined conveyor 310.

[0024] The pressing roller 120 device is located directly above the planar conveyor table 320. This pressing roller 120 device includes a pressing roller 120 located on the planar conveyor table 320, and a drive assembly 110 for driving the pressing roller 120 to a first set height and a second set height. The drive assembly 110 is driven by a lifting cylinder. When the drive assembly 110 drives the pressing roller 120 to the first set height, the pressing roller 120 avoids the planar conveyor table 320 while conveying the adhesive. When the drive assembly 110 drives the pressing roller 120 to the second set height, the pressing roller 120 rolls and presses against the overlap of the adhesive. Therefore, under the action of the adhesive receiving control assembly 400, which is equipped on the secondary conveying mechanism for detecting the head and tail end position information of the adhesive, when the adhesive receiving control assembly 400 receives the tail end information of the adhesive, it controls the secondary conveying mechanism to convey a set distance in a second direction. The set distance conveyed by the secondary conveying mechanism in the second direction is such that the tail end of the adhesive is directly below the primary conveying mechanism 210. When the glue supply control component 400 receives information that the head end of one glue material covers the tail end of another glue material, it controls the secondary conveying mechanism to convey the glue material along the first direction to directly below the pressing roller 120, and controls the pressing roller 120 to be at a second set height. At the same time, when the glue supply control component 400 receives information that the head end of one glue material covers the tail end of another glue material, it controls the primary conveying mechanism 210 and the secondary conveying mechanism to convey the glue material synchronously in the first direction.

[0025] In this application, after receiving the tail end information of the previous rubber material through the glue supply control component 400, it controls the secondary conveying mechanism to convey the material in the second direction, so that the tail end of the previous rubber material is below the primary conveying mechanism 210. The head end of the next rubber material falls to the detection end of the secondary conveying mechanism under the conveying of the primary conveying mechanism 210. At this time, the tail end of the previous rubber material is covered by the head end of the next rubber material, completing the head-tail overlap operation between the rubber materials. The glue supply control component 400 controls the primary conveying mechanism 210 and the secondary conveying mechanism to convey the material in the first direction at the same time, and move them directly below the pressing roller 120 device to complete the pressing operation. The overall operation process is simple and convenient, requires no manual intervention, and the pressing effect is firm and reliable.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of one or more embodiments of this specification should be included within the scope of protection of this disclosure.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
