Description

TECHNICAL FIELD

[0001] The application relates to the field of tire processing technology, in particular to a novel splicing machine. BACKGROUND

[0002] In the field of tire manufacturing, accurately and firmly splicing the strip-shaped tire blank into a ring-shaped structure is an important part to ensure the quality and performance of the tire. In this process, the splicing machine plays an indispensable role. The splicing machine is a specially designed device, and its core function is to efficiently press the joint part when the strip-shaped tire blank is formed into a ring-shaped structure. Through precise mechanical pressure, it can ensure that the materials at the joint part are tightly combined to form a seamless and reliable connection, which not only helps to improve the overall structural strength of the tire, but also effectively prevents air leakage or safety accidents caused by loose or damaged joints during use. Therefore, the splicing machine plays a crucial role in the tire manufacturing process, and its technical performance and operation precision directly affect the final quality and market competitiveness of the tire products.

[0003] The utility model patent with the patent application number 202420648789.0 discloses a splicing machine, which includes a rack, a support rod and a crossbeam arranged in sequence on the side of the rack, and a pressing drive assembly installed on the crossbeam, with its power output end connected to a pressing head assembly. The pressing head assembly includes a fixed part with a downward opening and a pressing head slidingly arranged in the fixed part, and a compressible cavity is formed between the end faces of the two parts. The cavity is filled with a plurality of steel balls, and when the pressing head acts on the strip-shaped embryo, the cavity is compressed, and each steel ball is uniformly laid in the cavity to provide a buffering effect. When the pressing head moves away from the strip-shaped embryo, the gravity of each steel ball causes the pressing head to reset relative to the fixed part. Although this application performs well in achieving efficient buffering effect, in actual operation, the worker needs to place both hands on the designated work station. If the splicing machine accidentally falls during the process of taking and placing the tire embryo due to misoperation, it is likely to cause extrusion injury to the worker's hands. More inconveniently, after completing the pressing operation, the formed ring-shaped embryo still needs to be manually taken down by relying on manual labor. This process not only consumes time and effort, but also further increases the labor intensity of the workers. In view of the above problems, there is an urgent need for an innovative safety structure for splicing, which aims to fundamentally improve the safety of the workers during the operation process, effectively avoid potential extrusion risks, and simplify the taking and placing process of the ring-shaped embryo to reduce the workload of the workers and achieve a more efficient and safe tire manufacturing operation environment. UTILITY MODEL CONTENT

[0004] The device provides a novel splicing machine, and the specific implementation is as follows:

[0005] A novel splicing machine includes:

[0006] The crimping assembly is connected with a driving assembly, and the top of the positioning base is used for placing a to-be-spliced part of a strip-shaped embryo body; the driving assembly drives the crimping assembly to crimp the to-be-spliced part;

[0008] The brake pedal is connected with the first cylinder and the driving assembly; the telescopic air arm of the first cylinder changes the abutting position of the sliding block and the wedge-shaped block, thereby adjusting the horizontal posture of the turnover shell to make the ring-shaped embryo body slide laterally after splicing is completed.

[0009] Preferably, the crimping assembly comprises a crimping head and a crimping shell which are slidingly connected, and a buffer is arranged between the crimping head and the crimping shell.

[0010] Based on the above technical scheme, the blanking assembly is hinged to the top of the positioning base, and the sliding block is driven to operate by the power of the first cylinder, so that the automatic downward turning action of the turnover shell after the embryo body crimping process is completed is realized, thereby ensuring that the embryo body can be smoothly and automatically separated from the turnover shell.

[0011] Preferably, the machine frame is further provided with a stand body, and a vertical column and a cross beam are sequentially arranged on the top of the stand body; the driving assembly is arranged on the cross beam, and the positioning base is arranged on the side of the vertical column.

[0012] Based on the above technical scheme, the machine frame bears and fixes the driving assembly, the positioning base and the blanking assembly. The driving assembly is designed as a hydraulic cylinder structure, and its working principle depends on the telescopic action of the air arm of the hydraulic cylinder, so that the crimping assembly is stably driven to be pressed downward, thereby ensuring that the joint of the tire embryo is tightly and uniformly pressed.

[0013] Preferably, the machine frame is further provided with a controller and a detection cabinet; the signal output end of the controller is electrically connected with the driving assembly and the first cylinder; a rack is vertically slidably arranged in the detection cabinet, and proximity switches are arranged at the upper and lower sliding limit ends of the rack; the hinge center of the turnover shell and the positioning base is engaged with the rack through gear transmission.

[0015] Preferably, a first tension spring is arranged between the opening and closing ends of the turnover shell and the positioning base.

[0016] Preferably, a limiting sliding groove is formed on the top of the positioning base along the length direction, and the limiting sliding groove is in sliding connection with the sliding block.

[0017] Preferably, a rotating shaft is arranged at the hinge between the turning shell and the positioning base, and the rotating shaft is coaxially arranged with the gear.

[0018] Based on the above technical scheme, after the first air cylinder retracts the gas arm, the turning shell can realize downward tilting by virtue of its own gravity and the weight of the embryo body, and the first tension spring can improve the effect and speed of downward tilting.

[0019] Preferably, the detection pedal electrically connected to the controller is further included, and the brake pedal and the detection pedal are arranged on the two sides of the stand column respectively.

[0020] Based on the above technical scheme, in order to ensure the accuracy and safety of the crimping process, the detection pedal is arranged, and before the actual operation of the crimping process, the worker needs to step on the detection pedal first, because it can trigger the comprehensive detection of the current posture of the turning shell in advance, and can identify and verify the position state of the turning shell in advance, so as to effectively avoid the misalignment in the subsequent crimping operation, greatly improve the crimping precision and product quality; at the same time, this process also serves as a safety barrier, which can prevent accidental operation caused by misstepping the brake pedal to a certain extent, and adds additional safety protection to the whole production process.
