Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of sealing strip processing, and more specifically, to an automatic punching machine for door rubber guide grooves. Background Technology

[0002] In the mass production of rubber guide channels for doors, the continuity of punching and the efficiency of material discharge directly affect the overall production capacity. Traditional punching equipment generally faces two major technical bottlenecks when processing these flexible rubber products: firstly, the continuous cutting efficiency is low, and secondly, the inability to achieve rapid material discharge leads to material accumulation, which seriously restricts the smoothness of the production line and the stability of product quality.

[0003] Because of their irregular cross-sectional structure, rubber guide grooves for doors are typically cut using a single-station intermittent operation mode in traditional punching machines. After each cut, manual resetting or waiting for the machine to return to its original position is required, resulting in a limited number of processing operations per unit time, which is insufficient to meet the needs of mass production. Furthermore, the elastic shrinkage properties of rubber make it prone to burrs or dimensional deviations due to uneven stress during the cutting process, further increasing the workload of subsequent finishing processes.

[0004] More importantly, the existing equipment's discharge mechanism is simply designed, relying heavily on gravity for natural descent. The smooth surface and irregular shape of the rubber guide channel make it prone to jamming and stacking at the discharge port. This accumulated material not only hinders subsequent workpieces from entering the processing station but can also deform already processed parts due to compression, affecting product precision. For automated production lines, this poor discharge can cause equipment downtime, disrupting the continuity of production. Therefore, developing an automatic punching machine for door rubber guide channels with efficient continuous cutting capabilities and rapid discharge has become an urgent need for the industry to improve production efficiency. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide an automatic punching and cutting machine for rubber guide grooves for doors, which solves the technical problems of low efficiency in continuous cutting and material accumulation caused by the inability to achieve rapid material discharge in the prior art.

[0006] According to one aspect, at least one embodiment of this disclosure provides an automatic punching machine for rubber guide grooves in doors, comprising: A platform and an upright plate, wherein the upright plate is fixed to one side of the surface of the platform; A positioning component is provided on the upright plate; A clamping and punching assembly is disposed on the frame and the upright plate; A tilting discharge assembly is mounted on the frame; The propulsion positioning component includes a rectangular opening, which is formed on the side surface of the upright plate. A pair of movable rods are movably connected to the side surface of the upright plate. One end of each movable rod is connected to a fixed frame. The bottom of the fixed frame and the top of the rectangular opening are both rotatably connected to rolling rods.

[0007] As a further technical solution, the rolling rods located at both ends of the bottom of the fixed frame are all driven to rotate by electricity. One end of the movable rod is provided with an anti-detachment block, and a spring is fitted on the movable rod. The spring is supported between the anti-detachment block and the side surface of the upright plate.

[0008] As a further technical solution, the pressing and punching assembly includes a cut, which is opened on the surface of the frame and located at the front end of the upright plate. A fixed seat is provided on the surface of the frame, and a telescopic cylinder is horizontally fixedly connected to the side surface of the fixed seat.

[0009] As a further technical solution, the output end of the telescopic cylinder is provided with a clamping frame, the side surface of the upright plate is provided with a notch, the notch is located corresponding to the clamping frame, and the top of the upright plate is provided with a telescopic hydraulic cylinder vertically downward.

[0010] As a further technical solution, the output end of the telescopic hydraulic cylinder is provided with a cutter, the side surface of the cutter is slidably attached to the front end face of the upright plate, the cutter is located directly above the cut, and a pair of stabilizing rods are provided on the top of the cutter, the stabilizing rods being vertically and movably connected to the upright plate.

[0011] As a further technical solution, the flipping discharge assembly includes a side opening, which is opened on the surface of the frame. A flipping plate is rotatably connected inside the side opening via a rotating shaft, and a gear is provided at one end of the rotating shaft of the flipping plate.

[0012] As a further technical solution, a second cylinder is provided on the side end face of the platform, and a rack is provided at the output end of the second cylinder. The rack meshes with the gear, and the tipping plate is located on the rubber strip conveying path.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the propulsion positioning assembly solves the problem of unstable propulsion of the rubber guide channel by combining elastic clamping with power transmission.

[0022] like Figures 1-3 The diagram illustrates an automatic punching machine for rubber guide grooves for doors, according to an embodiment of this disclosure, comprising: The platform 1 and the upright plate 2 are fixed to one side of the surface of the platform 1; A positioning component 3 is propelled and disposed on the upright plate 2; A pressing and punching assembly 4 is disposed on the frame 1 and the upright plate 2; A tilting discharge assembly 5 is mounted on the frame 1. The propulsion positioning component 3 includes a rectangular opening 3-1, which is formed on the side surface of the upright plate 2. A pair of movable rods 3-2 are movably connected to the side surface of the upright plate 2. One end of each movable rod 3-2 is connected to a fixed frame 3-3. The bottom of the fixed frame 3-3 and the top of the rectangular opening 3-1 are rotatably connected to rolling rods 3-4. The rolling rods 3-4 at both ends of the bottom of the fixed frame 3-3 are electrically driven to rotate. One end of each movable rod 3-2 is provided with an anti-detachment block 3-5. A spring 3-6 is fitted on the movable rod 3-2, and the spring 3-6 is supported between the anti-detachment block 3-5 and the side surface of the upright plate 2.

[0023] In some examples, the continuous advancement and stable positioning of the rubber guide groove for the door is achieved by advancing the positioning component 3. A rectangular opening 3-1 on the side surface of the upright plate 2 provides a passageway for the rubber guide groove. A pair of movable rods 3-2 are horizontally mounted on the side surface of the upright plate 2. A fixed bracket 3-3 connected to one end can move laterally with the movable rods 3-2. A rolling rod 3-4, rotatably connected at its bottom to the top of the rectangular opening 3-1, forms an upper and lower clamping structure. The rolling rods 3-4 at both ends of the bottom of the fixed bracket 3-3 are electrically driven to rotate, providing power for the conveying of the rubber guide groove. An anti-detachment block 3-5 at one end of the movable rod 3-2 prevents it from detaching from the upright plate 2. A spring 3-6 mounted on the movable rod 3-2 supports it between the anti-detachment block 3-5 and the side surface of the upright plate 2, providing elastic pressure to the fixed bracket 3-3 towards the inside of the rectangular opening 3-1.

[0024] During operation, spring 3-6 pushes the fixed frame 3-3, causing the upper and lower rolling rods 3-4 to clamp the rubber guide groove. The electrically driven rolling rods 3-4 rotate, propelling the rubber guide groove forward along the rectangular opening 3-1. When the size of the rubber guide groove fluctuates, the elastic deformation of spring 3-6 can adaptively adjust the clamping force to avoid excessive compression or loosening. The rotational conveying of rolling rods 3-4 ensures continuous and stable propulsion, while the elastic clamping of spring 3-6 keeps the rubber guide groove centered during propulsion, preventing deviation. The fitted cooperation between movable rod 3-2 and vertical plate 2 restricts the movement direction of fixed frame 3-3, ensuring clamping accuracy. The cooperation of upper and lower rolling rods 3-4 provides both driving force and positioning constraint, ensuring that the rubber guide groove maintains a stable posture during propulsion, providing a precise positional basis for subsequent punching processes. This component achieves continuous and stable conveying and positioning of the rubber guide groove through the synergy of elasticity and power.

[0025] like Figures 1-3As shown in the figure, the pressing and punching assembly 4 in this embodiment includes a cut 4-1, which is formed on the surface of the frame 1 and located at the front end of the upright plate 2. A fixed seat 4-2 is provided on the surface of the frame 1. A telescopic cylinder 4-3 is horizontally fixedly connected to the side surface of the fixed seat 4-2. A pressing frame 4-4 is provided at the output end of the telescopic cylinder 4-3. A notch 4-5 is provided on the side surface of the upright plate 2 and is located opposite to the pressing frame 4-4. A telescopic hydraulic cylinder 4-6 is vertically downwardly provided at the top of the upright plate 2. A cutter 4-7 is provided at the output end of the telescopic hydraulic cylinder 4-6. The side surface of the cutter 4-7 is slidably attached to the front end face of the upright plate 2. The cutter 4-7 is located directly above the cut 4-1. A pair of stabilizing rods 4-8 are provided at the top of the cutter 4-7 and are vertically and movably connected to the upright plate 2.

[0026] In some examples, the rubber guide groove is smoothly cut by clamping the punching assembly 4. The cut 4-1 on the surface of the stand 1 is located at the front end of the upright plate 2, providing space for the cutter 4-7 to descend. The telescopic cylinder 4-3 on the fixed seat 4-2 on the surface of the stand 1 is horizontally set, and the clamping frame 4-4 connected to the output end can move laterally under the drive of the cylinder. The notch 4-5 on the side surface of the upright plate 2 provides clearance for the clamping frame 4-4, ensuring that it can fit against the surface of the rubber guide groove. The output end of the telescopic hydraulic cylinder 4-6 vertically downward at the top of the upright plate 2 is connected to the cutter 4-7. The side surface of the cutter 4-7 slides against the front end of the upright plate 2, ensuring vertical movement during punching. A pair of stabilizing rods 4-8 at the top are vertically and movablely fitted with the upright plate 2, enhancing the stability of the cutter 4-7's movement. The cutter 4-7 is located directly above the cut 4-1, forming a precise punching structure.

[0027] During operation, after the rubber guide groove is pushed to the punching position, the telescopic cylinder 4-3 drives the clamping frame 4-4 to extend and press against the surface of the rubber guide groove from the notch 4-5. Subsequently, the telescopic hydraulic cylinder 4-6 drives the cutter 4-7 to slide down along the front end face of the vertical plate 2, pass through the rubber guide groove, and enter the cut 4-1 to complete the punching. After punching, the cutter 4-7 and the clamping frame 4-4 are reset sequentially, waiting for the next operation. The front clamping of the clamping frame 4-4 prevents the rubber guide groove from shifting during punching, ensuring a flat cut surface. The sliding contact between the cutter 4-7 and the vertical plate 2, and the guidance of the stabilizing rod 4-8, ensure that the punching direction is perpendicular, improving cutting accuracy. The cut 4-1 provides a buffer space for the cutter 4-7 to prevent damage to the blade. The step-by-step actions of each component are coordinated through program control, making the punching process stable and orderly, and greatly improving the quality and efficiency of cutting the rubber guide groove.

[0028] like Figures 1-3As shown in the figure, the present embodiment proposes that the flipping discharge assembly 5 includes a side opening 5-1, which is opened on the surface of the frame 1. A flipping plate 5-2 is rotatably connected to the side opening 5-1 through a rotating shaft. A gear 5-3 is provided at one end of the rotating shaft of the flipping plate 5-2. A second cylinder 5-4 is provided on the side end face of the frame 1. A rack 5-5 is provided at the output end of the second cylinder 5-4. The rack 5-5 meshes with the gear 5-3. The flipping plate 5-2 is located on the rubber strip conveying path.

[0029] In some examples, the rapid discharge of the punched rubber guide channel is achieved by flipping the discharge assembly 5. The side opening 5-1 on the surface of the frame 1 is located on the conveying path of the rubber guide channel. The flipping plate 5-2, which is rotatably connected to the inside via a rotating shaft, can be flipped downwards to allow the cut portion to slide down. The gear 5-3 at one end of the rotating shaft of the flipping plate 5-2 meshes with the rack 5-5 at the output end of the second cylinder 5-4 on the side end face of the frame 1, forming a flipping drive structure.

[0030] During operation, after the rubber guide channel is cut, the second cylinder 5-4 drives the rack 5-5 to retract, which in turn drives the tilting plate 5-2 to rotate downwards around the axis of rotation via the gear 5-3. Its surface is lower than the surface of the frame 1, causing the cut rubber guide channel segment to slide downwards. After discharge, the second cylinder 5-4 resets, the rack 5-5 drives the gear 5-3 to rotate in the opposite direction, and the tilting plate 5-2 flips downwards and resets to the surface of the frame 1, without affecting the subsequent conveying of the rubber guide channel. The meshing transmission between the gear 5-3 and the rack 5-5 allows for precise control of the tilting angle of the tilting plate 5-2, ensuring a stable discharge direction and preventing the accumulation of cut rubber guide channels on the conveying path. The side opening 5-1 provides space for the tilting plate 5-2 to move, preventing interference with the frame 1 during tilting. This component, in conjunction with the propulsion and cutting components, enables rapid transfer of cut materials, improves the continuous operation capability of the equipment, and ensures a smooth and efficient production process.

[0031] For example, such as Figure 2 As shown, the flipping plate 5-2 can be rotated downwards by 60° via the rotating shaft.

[0032] In some examples, the tilting plate 5-2 can be rotated downwards by 60° via the axial rotation. This angle design allows for precise guidance of the punched rubber guide channel as it slides out. When rotated downwards by 60°, the tilting plate 5-2 forms a suitable incline, allowing the rubber guide channel to quickly slide into the collection area under gravity, avoiding stagnation. Simultaneously, this angle ensures that the tilting plate 5-2 does not droop excessively and interfere with other components of the frame 1, and it can smoothly return to its initial position upon reset, without affecting subsequent rubber guide channel conveying, thus improving discharge efficiency and equipment coordination.

[0033] In actual use: The rubber guide groove enters the rectangular opening 3-1 of the upright plate 2. The spring 3-6 on the movable rod 3-2 pushes the fixed frame 3-3, causing the bottom of the fixed frame 3-3 to clamp the guide groove with the rolling rod 3-4 at the top of the rectangular opening 3-1. The electrically driven rolling rod 3-4 rotates, driving the guide groove forward. The spring 3-6 adaptively adjusts the clamping force to accommodate fluctuations in the guide groove size. After the guide groove reaches the punching position, the telescopic cylinder 4-3 drives the clamping frame 4-4 to extend from the notch 4-5 to clamp the surface of the guide groove. The telescopic hydraulic cylinder 4-6 at the top of the upright plate 2 drives the cutter 4-7 to slide down along the front end face, completing the punching through the cut 4-1. The stabilizing rod 4-8 ensures that the cutter 4-7 moves vertically. After punching, the second cylinder 5-4 drives the rack 5-5 to retract, which in turn drives the gear 5-3 to flip the tilting plate 5-2 downward by 60°. The guide groove slides out along the tilting plate 5-2, and then the tilting plate 5-2 resets, waiting for the next section of the guide groove to advance. The entire process realizes continuous automatic punching and unloading.
