Description

Technical Field

[0001] This utility model belongs to the technical field of material feeding mechanism, and in particular relates to a rubber sealing ring cutting device with continuous feeding function. Background Technology

[0002] Rubber seals are precision components widely used in machinery, automobiles, hydraulics, pneumatics, and aerospace. They are typically made of highly elastic rubber materials and are ring-shaped or have other specific cross-sectional shapes. Through their elastic deformation, they fill gaps, thereby sealing the medium, preventing leakage, and isolating dust. In the production process of rubber seals, the compounded rubber is first extruded into continuous long strips with specific cross-sectional shapes using an extruder. These continuous long strips are then cut into rings of predetermined lengths, and finally vulcanized to form the final product. The cutting process is a crucial step, as the cutting accuracy and efficiency directly affect the dimensional consistency of the product, the quality of the joints, and the final production efficiency. The equipment used to complete this process is called a rubber seal cutting device.

[0003] Existing rubber sealing ring cutting devices still have some problems during use. For example, after each round of cutting, the production process must be interrupted and manual feeding is required. This intermittent production mode not only increases the labor intensity of operators, but also seriously restricts the production efficiency and automation level of the equipment, making it impossible to achieve continuous and large-scale production, thus becoming a bottleneck in improving the overall production line.

[0004] To address these issues, we provide a rubber sealing ring cutting device with continuous feeding function. Utility Model Content

[0005] The purpose of this utility model is to provide a rubber sealing ring cutting device with continuous feeding function. By using the feeding mechanism and the replenishing mechanism in combination, the problem of the current rubber sealing ring cutting device having to interrupt the production process after each round of cutting and relying on manual feeding is solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a rubber sealing ring cutting device with continuous feeding function, comprising a cutting box, a cutting blade assembly and a supporting assembly on one side of the inside of the cutting box, a discharge assembly at the bottom of the cutting box, and a feeding mechanism on one side of the inside of the cutting box. The feeding mechanism includes a feeding assembly on one side of the inside of the cutting box, a closed box on one side of the feeding assembly, and a closing assembly inside the closed box. A replenishing mechanism is provided on one side of the cutting box, comprising a fixed frame fixedly connected to one side of the inside of the cutting box, a channel box fixedly connected to the fixed frame, a conveying box fixedly connected to one side of the cutting box, and a pushing assembly on one side of the conveying box.

[0008] The present invention is further configured such that the feeding assembly includes a first hydraulic cylinder fixedly connected to one side of the fixed frame, a feeding pipe fixedly connected to one side of the enclosed box, and a slide rod fixedly connected to the other side of the enclosed box.

[0009] The present invention is further configured such that the sealing assembly includes a second hydraulic cylinder fixedly connected to one side of the sealing box, a push plate fixedly connected to the output end of the second hydraulic cylinder, a sealing plate fixedly connected to one side of the push plate, and a limiting rod fixedly connected inside the sealing box.

[0010] The present invention is further configured such that the cutting box, the enclosed box, the fixed frame, the channel box and the conveying box are all provided with feeding channels, and a feeding inclined plate is fixedly connected to the top of one side of the conveying box.

[0011] The present invention is further configured such that the pushing assembly includes an extension plate fixedly connected to one side of the conveying box, a third hydraulic cylinder fixedly connected to one side of the extension plate, a moving plate fixedly connected to the output end of the third hydraulic cylinder, an extension rod fixedly connected to one side of the moving plate, and a feeding plate fixedly connected to the other end of the extension rod.

[0012] The present invention is further configured such that the cutting blade assembly includes a transverse moving box fixedly connected inside the cutting box, a longitudinal moving box disposed on the top of the transverse moving box, and a cutting blade fixedly connected to the top of the longitudinal moving box.

[0013] The present invention is further configured such that the supporting component includes a rotating component fixedly connected to one side of the inside of the cutting box, a supporting roller fixedly connected to one side of the rotating component, and a pusher plate sleeved on the surface of the supporting roller.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model achieves continuous production through the coordinated movement of the pushing component in the feeding mechanism and the feeding mechanism. The third hydraulic cylinder drives the feeding plate to push the rubber strip into the feeding pipe through the continuous feeding channel to complete the material preparation. Subsequently, the first hydraulic cylinder pushes the entire enclosed box and feeding pipe to move, directly pushing the rubber strip onto the support roller, replacing the traditional manual feeding. This allows the equipment to start the next round of operation immediately after completing one round of cutting, reducing the time interval of downtime for feeding, and effectively improving the utilization rate of the equipment and the overall production efficiency.

[0017] 2. This utility model effectively solves the problems of slippage and misalignment in automatic feeding through the closed component and guide design. During the process of pushing the rubber strip through the feeding tube, the second hydraulic cylinder drives the closing plate to close the feeding channel, preventing the rubber strip from retracting into the feeding channel under axial pressure. At the same time, the slide bar provides rigid lateral limit and support for the forward closed box, so that the rubber strip can be accurately fitted onto the surface of the support roller.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] For a specific implementation example, please refer to Implementation Example 1. Figures 1-6 This utility model is a rubber sealing ring cutting device with continuous feeding function, including a cutting box 1, a cutting blade assembly 2 and a supporting assembly 3 inside the cutting box 1, a discharge assembly 4 at the bottom of the cutting box 1, a feeding mechanism 5 inside the cutting box 1, the feeding mechanism 5 including a feeding assembly 51 inside the cutting box 1, a closed box 52 inside the feeding assembly 51, and a closing assembly 53 inside the closed box 52, and a replenishing mechanism 6 on one side of the cutting box 1, the replenishing mechanism 6 including a fixed frame 61 fixedly connected to one side of the cutting box 1, a channel box 62 fixedly connected to the fixed frame 61, a conveying box 63 fixedly connected to one side of the cutting box 1, and a pushing assembly 64 on one side of the conveying box 63.

[0029] Specifically, the core function of the feeding mechanism 5 is to automatically fit the rubber sealing rings to be cut onto the support rollers of the support assembly 3, replacing the traditional manual feeding operation. First, the first hydraulic cylinder 511 is activated, pushing the sealing box 52 and the feeding pipe 512 fixed thereto to move horizontally towards the support rollers. The slide rod 513 slides in the sliding through hole to provide guidance and support, ensuring smooth movement. At this time, the sealing plate 533 in the sealing assembly 53 is in a closed state. The first hydraulic cylinder 511 continues to push, and the rubber sealing rings pre-placed in the feeding pipe 512 are directly fitted onto the surface of the rotating support rollers under the continuous pushing of the feeding pipe 512, completing the feeding. The function of the replenishing mechanism 6 is to... After the feeding mechanism 5 completes one feeding cycle, it automatically transports the new rubber strip to be cut from the storage position to the feeding pipe 512, preparing for the next feeding cycle and realizing continuous feeding. During the replenishment process, the sealing plate 533 moves to one side, so that the feeding channel is in a connected state. The outer rubber strip slides down through the feeding inclined plate 7 into the feeding channel of the conveying box 63. The third hydraulic cylinder 642 drives the moving plate 643, which in turn drives the extension rod 644 and the feeding plate 645 to move forward. The feeding plate 645 pushes the rubber strip along the feeding channel that is connected inside the conveying box 63, the channel box 62 and the fixed frame 61, and continuously pushes it into the feeding pipe 512 until the rubber strip reaches the predetermined position, preparing the material for the next feeding action.

[0030] For a specific embodiment two, please refer to Figures 1-6Based on the first specific embodiment, the feeding assembly 51 includes a first hydraulic cylinder 511 fixedly connected to one side of the fixed frame 61, a feeding pipe 512 fixedly connected to one side of the enclosed box 52 with both ends of the feeding pipe 512 being open, and a sliding rod 513 fixedly connected to the other side of the enclosed box 52. Both the cutting box 1 and the fixed frame 61 have sliding through holes adapted to the sliding rod 513. The enclosing assembly 53 includes a second hydraulic cylinder 531 fixedly connected to one side of the enclosed box 52, a push plate 532 fixedly connected to the output end of the second hydraulic cylinder 531, a closing plate 533 fixedly connected to one side of the push plate 532, and a sealing plate 533 fixedly connected to the other side of the enclosed box 52. The limiting rod 534 inside the closed box 52 has a limiting through hole inside the push plate 532, and the limiting rod 534 is located inside the limiting through hole. The cutting box 1, closed box 52, fixed frame 61, channel box 62, and conveying box 63 all have feeding channels inside. A feeding inclined plate 7 is fixedly connected to the top of one side of the conveying box 63. The pushing assembly 64 includes an extension plate 641 fixedly connected to one side of the conveying box 63, and a third hydraulic cylinder 642 fixedly connected to one side of the extension plate 641. The working principle of the hydraulic cylinder is to use pressurized liquid to transmit pressure in a closed space, acting on the piston to generate a huge linear thrust, thereby driving the load movement. This is existing technology. The solution will not be elaborated upon further, and those skilled in the art can clearly understand its working principle. A movable plate 643 is fixedly connected to the output end of the third hydraulic cylinder 642; an extension rod 644 is fixedly connected to one side of the movable plate 643; and a feeding plate 645 is fixedly connected to the other end of the extension rod 644. The cutting blade assembly 2 includes a transverse moving box fixedly connected inside the cutting box 1, a longitudinal moving box located at the top of the transverse moving box, and a cutting blade fixedly connected to the top of the longitudinal moving box. Both the transverse and longitudinal moving boxes have servo motors fixedly connected inside, and ball screw pairs fixedly connected to the output end of the servo motors. This is prior art, and this solution does not... The working principle is readily understood by those skilled in the art. The supporting component 3 includes a rotating component fixedly connected to one side of the inside of the cutting box 1, a supporting roller fixedly connected to one side of the rotating component, and a pusher plate sleeved on the surface of the supporting roller. The rotating component includes a servo motor fixedly connected to the inside of the cutting box and a synchronous belt drive system set at the output end of the servo motor. The supporting roller is fixedly connected to the synchronous belt drive system, which is prior art. This solution will not be elaborated further, and the working principle is readily understood by those skilled in the art. The discharging component 4 includes a discharge sloping plate set at the bottom of the inside of the cutting box 1 and a conveyor belt set at the bottom of the discharge sloping plate.

[0031] Specifically, the feeding component 51 is used to place the rubber sealing ring to be cut on the surface of the support roller on the support component 3. The first hydraulic cylinder 511 is used to push the sealing box 52 and the feeding pipe 512 towards the support component 3. The rubber strip is located inside the feeding pipe 512. The slide bar 513 provides lateral limiting support when the sealing box 52 moves. The sealing component 53 is used to close the feeding channel in the sealing box 52 that communicates with the feeding pipe 512 when the feeding component 51 is feeding, thus preventing the rubber sealing ring from being cut during the feeding process. The rubber sealing ring slides towards the closed box 52, preventing it from being squeezed onto the support roller of the support assembly 3. The second hydraulic cylinder 531 drives the push plate 532 to move, which in turn moves the closing plate 533 to the feeding chute. The closing plate 533 closes the feeding chute, and the limiting rod 534 limits the push plate 532, causing it to slide in a fixed position. The feeding chute then conveys the rubber sealing ring to be cut into the feeding pipe 512. The feeding inclined plate 7 causes the outer rubber strip to slide down into the conveying pipe. In the feeding channel of the feeding box 63, the rubber sealing ring sliding off the feeding inclined plate 7 is pushed towards the upward feeding pipe 512 by the setting of the pushing component 64. The third hydraulic cylinder 642 drives the moving plate 643 and the extension rod 644 to move. The extension rod 644 drives the feeding plate 645 to move towards the upward feeding pipe 512. The feeding plate 645 pushes the rubber strip in the feeding box 63 towards the upward feeding pipe 512. Through the setting of the cutting blade component 2, the servo motor drives the ball screw pair to rotate, and the position of the cutting blade is adjusted horizontally and vertically. The cutting blade is used to cut... The rubber sealing ring fitted on the surface of the support roller is cut to a fixed width. With the support component 3, the rubber strip is tightly fitted on the surface of the support roller. The servo motor in the rotating component drives the synchronous belt drive system to rotate, which in turn drives the support roller to rotate, facilitating the cutting blade to cut. The hydraulically driven pusher plate fitted on the surface of the support roller pushes the cut rubber sealing ring to one side. With the discharge component 4, the pushed rubber sealing ring slides onto the conveyor belt after being guided by the discharge inclined plate and is then transported outward by the conveyor belt.

[0032] The operation process of this embodiment is as follows: The continuous long rubber strip to be cut slides down the feeding inclined plate 7 into the feeding channel of the conveying box 63. The third hydraulic cylinder 642 of the feeding mechanism 6 is activated, driving the moving plate 643, the extension rod 644 and the feeding plate 645 to move forward, pushing the rubber strip into the feeding pipe 512 along the feeding channel in the channel box 62 and the fixed frame 61. Subsequently, the first hydraulic cylinder 511 of the feeding mechanism 5 is activated, pushing the sealing box 52 and the feeding pipe 512 as a whole to move horizontally towards the support roller. The sliding rod 513 provides guiding support. During this process, in order to prevent the rubber strip from slipping back due to resistance when being sleeved, the sealing component 53... The sealing plate 533 moves under the drive of the second hydraulic cylinder 531, sealing the feeding channel in the sealing box 52 that is connected to the feeding pipe 512, thus preventing backflow and avoiding the rubber strip from sliding back into the sealing box 52 during the installation process. Then, the feeding pipe 512, together with the rubber strip placed inside, continues to move forward. When one end of the rubber strip begins to be fitted onto the support roller, the sealing plate 533 provides constraint at the other end of the rubber strip. Under the continuous push of the feeding pipe 512, the rubber strip is accurately fitted onto the support roller. After the feeding is completed, all the actuators reset, and the feeding mechanism 6 begins the next push, pushing the rubber strip into the feeding pipe 512 to prepare for continuous production.

[0033] The rotating motor of the support assembly 3 drives the support roller to rotate. The transverse and longitudinal moving boxes of the cutting blade assembly 2 drive the cutting blade to be precisely positioned and perform circumferential cutting on the rotating rubber strip. After the cutting is completed, the pusher plate pushes the formed sealing ring blank out of the support roller. The falling sealing ring is guided by the discharge inclined plate and slides down to the conveyor belt for output.
