Description

Technical Field

[0001] This utility model relates to tire production equipment, specifically an automatic cutting device for a steel cord fabric cutting machine. Background Technology

[0002] Steel cord fabric refers to a tire manufacturing component in which rubber is covered on steel cords.

[0003] On the fabric calendering machine, steel cords are covered with rubber to form steel cord fabric rolls. On the steel cord fabric cutting machine, they are cut at different angles and widths. The cut steel cord fabric is a parallelogram with a certain angle and width. After passing through the splicing device, slitting device, edge binding device, and winding device, it is then rolled up for use by the forming machine.

[0004] During the automatic cutting process of the steel wire curtain fabric through the winding device, quality problems may occur, such as the steel wires of the steel wire curtain fabric not being cut due to the cutting blade, or the steel wire curtain fabric after edging not being cut.

[0005] The traditional automatic winding and cutting mechanism first lifts the material, the cutter hooks the steel wire curtain, and cuts from one end to the other using the blade. Due to the shape of the cutter and the edge of the steel wire curtain, it is inevitable that the steel wire curtain will not be cut completely, resulting in waste of steel wire curtain and production line downtime, which in turn increases the production cost of manufacturing enterprises. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model proposes an automatic cutting device for a steel wire cord fabric cutting machine.

[0007] An automatic cutting device for steel wire cord fabric cutting machines that can solve the problems of existing technologies includes a steel wire cord fabric conveying mechanism, a cutting knife mechanism, a cutting knife rotation mechanism, and a cutting knife moving mechanism, wherein:

[0008] 1. The steel wire cord conveying mechanism includes a conveyor belt that transports steel wire cord fabric forward under the drive of a motor.

[0009] 2. The cutting blade rotation mechanism is located above the conveyor belt and includes a swing frame that rotates under the drive of servo motor I. The angle between the swing frame and the front and rear directions is equal to the cutting angle of the steel wire curtain. A blade rest connected to the swing frame and pressed on the conveyor belt is provided below the swing frame. A guide ramp is provided at the rear end of the blade rest to facilitate the steel wire curtain to climb over the blade rest.

[0010] 3. The cutting blade moving mechanism includes a linear guide rail pair located at the bottom of the swing frame and a synchronous belt drive pair driven by servo motor II.

[0011] 4. The cutting mechanism includes a disc hob aligned with the cutter rest. The disc hob is mounted on a cylinder-driven lifting assembly via a cutter holder assembly. The lifting assembly is mounted on a machine base. The machine base is mounted on a linear guide pair and reciprocates under the drive of a synchronous belt transmission pair.

[0012] One floating structure of the tool holder assembly includes a tool holder, which is mounted on a fixed base via a bearing. The fixed base is mounted on a lifting assembly via a sliding pair coaxial with the disc hob and is centrally positioned by elastic elements on both axial sides.

[0013] Furthermore, the disc hob is mounted on the cutter holder via a heat-conducting mandrel, and a heating rod is mounted on the heat-conducting mandrel.

[0014] Furthermore, several magnets are embedded at the front and rear ends of the conveyor belt.

[0015] The beneficial effects of this utility model are:

[0016] This utility model of an automatic cutting device for steel wire cord fabric cutting machine solves the problem of automatic cutting devices failing to cut steel wire cord fabric, improves the quality and stability of automatic cutting of steel wire cord fabric, realizes automated production, reduces labor intensity, and improves production efficiency.

[0017] 1. This utility model has a steel wire cord conveyor belt structure of a certain length and stability, as well as a corresponding number of magnets, to ensure the stability of the steel wire cord during the cutting process.

[0018] 2. This utility model has a disc-shaped cutting blade and a blade rest with a sloping guide, which avoids the problem that traditional hook blades cannot completely cut the edge of the steel wire curtain, and makes it easy for the steel wire curtain to pass through.

[0019] 3. The cutting mechanism of this utility model with a floating structure avoids the problem of the cutting blade breaking due to the large resistance of the steel wire during the cutting process.

[0020] 4. This utility model has an independent angle adjustment and displacement drive mechanism, which uses a synchronous belt and an encoder for precise positioning, and can meet the specifications of steel wire curtains with different widths and angles. Attached Figure Description

[0028] The technical solution of this utility model will be further described below with reference to the embodiments shown in the accompanying drawings.

[0029] The present invention relates to an automatic cutting device for steel wire cord fabric cutting machine, comprising a steel wire cord fabric conveying mechanism 1, a cutting knife mechanism 2, a cutting knife rotating mechanism 3, and a cutting knife moving mechanism 4.

[0030] The steel wire cord conveying mechanism includes a conveyor belt 1-1 arranged in a front-to-back direction. Several magnets 7 are provided at both the front and rear ends of the conveyor belt 1-1. Driven by a reducer I driven by a motor 1-2, the conveyor belt 1-1 transports the steel wire cord 5 from back to front to a designated position. Figure 1 , Figure 2 As shown.

[0031] The cutting blade rotation mechanism 3 includes an arched swing frame 3-1 that spans above the conveyor belt 1-1. The swing frame 3-1 is mounted on the crossbeam of the frame 8 via a rotation mechanism 9 with an encoder. The rotation mechanism 9 rotates the swing frame 3-1 around its axis under the drive of a reducer II driven by a servo motor 3-2, so that the swing frame 3-1 forms an angle with the forward conveying direction of the steel wire curtain 5. This angle is consistent with the cutting angle of the steel wire curtain 5. A blade rest 6 is installed between the two ends of the arched bottom of the swing frame 3-1, pressing against the conveyor belt 1-1. A guide ramp is provided at the rear of the blade rest 6 (facing the direction of the steel wire curtain 5). Figure 1 , Figure 2 , Figure 3 As shown.

[0032] The cutting blade moving mechanism 4 includes a linear guide rail pair 4-1 and a synchronous belt drive pair 4-2 located at the bottom of the swing frame 3-1. The linear guide rail pair 4-1 includes a slide block that slides on the linear guide rail. The synchronous belt drive pair 4-2 includes a driving and a driven pulley connected by a synchronous belt. The driving pulley is driven by a servo motor II 4-3 and a reducer III. Figure 1 , Figure 3 , Figure 4 As shown.

[0033] The cutting mechanism 2 includes a disc cutter 2-1 aligned with the cutter rest 6. The disc cutter 2-1 is mounted on a lifting assembly 2-5 driven by a cylinder 2-4 via a blade holder assembly with a floating structure. The lifting assembly 2-5 is mounted on a base 2-3. The base 2-3 is mounted on a slide of a linear guide pair 4-1 and connected to a synchronous belt of a synchronous belt drive pair 4-2. The synchronous belt drives the disc cutter 2-1 to reciprocate along the linear guide. Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown.

[0034] The tool holder assembly includes a tool holder 2-6, which is mounted on the bottom of a fixed base 2-8 via a bearing 2-7. An directional structure 2-12 is also provided between the bottom of the fixed base 2-8 and the tool holder 2-6 to ensure that the running direction of the disc hob 2-1 corresponds to the tool rest 6. The fixed base 2-8 is mounted in the lifting frame of the lifting assembly 2-5 via a sliding pair 2-9 coaxial with the disc hob 2-1. The lifting frame is mounted on the machine base 2-3 via a sliding structure. Elastic elements 2-10 are provided on both axial sides of the lifting frame to centrally position the fixed base 2-8. The disc hob 2-1 is mounted in the tool holder 2-6 via a heat-conducting spindle 2-11. A heating rod 2-2 is mounted on the heat-conducting spindle 2-11. Figure 5 , Figure 6 As shown.

[0035] The operating mode of this utility model is as follows:

[0036] 1. Start the servo motor 3-2, and adjust the swing of the swing frame 3-1 according to the cutting angle of the steel wire curtain 5 so that the angles of the two are consistent. At this time, the disc cutter 2-1 rises and stays at the starting position on the left.

[0037] 2. The steel wire curtain 5 is attracted to the conveyor belt 1-1 by the magnet 7. The motor 1-2 is started, and the conveyor belt 1-1 transports the steel wire curtain 5 forward to the set position in front of the cutting blade rotating mechanism 3. When passing the cutting blade rotating mechanism 3, the steel wire curtain 5 climbs over the blade rest 6 through the guide ramp.

[0038] 3. When cylinder 2-4 is started, the disc cutter 2-1 is lowered and pressed onto the left end of the cutter rest 6. Servo motor II 4-3 is started, and the synchronous belt drives the disc cutter 2-1 to move from left to right on the cutter rest 6. During operation, the disc cutter 2-1 completes the cutting and trimming of the steel wire curtain 5 on the cutter rest 6.

[0039] During the cutting process, when the disc roller 2-1 encounters the steel wire of the steel wire curtain 5, the resistance will increase. The disc roller 2-1 can achieve slight deflection through the floating structure (bearing 2-7 + elastic element 2-10) to avoid blade breakage.

[0040] 4. After cutting the steel wire curtain 5, the disc cutter 2-1 rises upward, and the synchronous belt runs in the opposite direction, driving the disc cutter 2-1 from right to left back to the origin.

[0041] 5. The conveyor belt 1-1 moves forward and transports the cut steel wire cord fabric 5 to the next working position for winding.
