Description

Technical Field

[0001] This utility model relates to the field of molding equipment, and in particular to a soundproof door curtain slat molding machine. Background Technology

[0002] Door curtain forming machines play a vital role in building decoration and industrial production. They are primarily used to cold-bend metal sheets (such as stainless steel and color steel plates) into door curtain slats for roller shutters. Among these, sound-absorbing door curtains are widely popular in the market due to their ability to effectively reduce noise transmission. To ensure that market demands are met, the production quality and efficiency of sound-absorbing door curtain slats are crucial.

[0003] The workflow of a traditional door curtain slat forming machine includes material entering from the back of the mold, being shaped through a specific forming process, and then cutting. The shape and size of the mold can be flexibly adjusted according to actual needs to adapt to the production of different specifications and types of soundproof door curtain slats. However, after cutting, the exit in front of the mold often lacks a suitable restraining device, which can cause the formed curtain slats to easily shift left or right if they are not caught manually in time when they fall.

[0004] This misalignment not only affects the quality and aesthetics of the slats, but can also cause collisions between slats, resulting in noise and damage. Furthermore, during subsequent collection and sorting processes, misaligned slats increase the complexity and difficulty of operations, further reducing production efficiency.

[0005] To address this issue, an improved soundproof door curtain slat forming machine was proposed. This machine incorporates a limiting device at the exit in front of the mold, effectively preventing the formed curtain slats from shifting left or right when falling. Utility Model Content

[0006] This invention addresses the shortcomings of existing technologies by using symmetrically arranged guide plates at both ends of the curtain slat mold outlet to effectively limit the horizontal movement of the curtain slats during drop. When the curtain slats fall from the mold outlet and are not handled manually in time, the guide plates prevent the curtain slats from shifting left or right. This ensures that the curtain slats remain neat in their initial state after forming, avoiding deformation caused by shifting, thereby guaranteeing the shape accuracy of the soundproof door curtain slats and enabling them to better meet the installation and use requirements in architectural decoration and industrial production.

[0007] In order to solve the above-mentioned technical problems, the present invention solves the problem that if the formed curtain slats are not caught by humans in time when they fall, they are prone to left and right deviation through the following technical solution.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A soundproof door curtain slat forming machine includes a device body, on which a forming device is installed. The forming device has a curtain slat mold for forming curtain slats. The two ends of the outlet of the curtain slat mold are symmetrically provided with guide plates. The front end of the forming device has a discharge port for discharging the curtain slats. The two sides of the front end of the forming device are symmetrically provided with support frames. The guide plates can move back and forth relative to the support frames. A collection frame is placed on the device body and is located directly below the discharge port.

[0010] Preferably, the support frame has a longitudinal groove and a transverse channel inside, and one end of the guide plate is connected to an adjusting rod, which can enter along the channel and slide back and forth in the groove.

[0011] Preferably, the portion of the adjusting rod that passes through the groove and channel is provided with an external thread, and a locking kit is rotatably connected to the thread to fix or adjust the position of the guide plate.

[0012] Preferably, the locking kit has a stabilizing pad on top.

[0013] Preferably, the stabilizing pad is made of rubber and can form a tight contact with the bottom of the device body.

[0014] Preferably, a protective layer is glued to the inner end face of the guide plate to protect the curtain slats.

[0015] Preferably, the support frame is connected to a fixing plate on its side, and the fixing plate is connected to the corresponding position on the outer wall of the device body by bolts.

[0016] Preferably, a guide plate is movably installed inside the discharge port to guide the curtain slats to fall into the collection frame. The guide plate has a smooth surface and a curved shape.

[0017] Preferably, the inner rear end of the discharge port is symmetrically provided with recessed mounting grooves on both sides, and a rotating rod structure is bolted between the two recessed mounting grooves. One end of the guide plate is rotatably connected to the rotating rod structure, and the other end faces the opening of the guide plate.

[0018] Preferably, a stop block is provided at the rear end of the bottom of the guide plate, and a buffer spring is provided between the stop block and the guide plate. A mounting bracket is connected to the bottom of the discharge port by bolt thread, and a stabilizing sleeve is connected to the mounting bracket, into which the stop block is inserted.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The soundproof door curtain slat forming machine provided in this application effectively restricts the horizontal movement of the curtain slats during drop by using guide plates symmetrically arranged at both ends of the curtain slat mold outlet. When the curtain slats fall from the mold outlet and are not handled manually in time, the guide plates prevent the curtain slats from shifting left or right. This ensures that the curtain slats remain neat in their initial state after forming, avoiding deformation caused by shifting, thereby guaranteeing the shape accuracy of the soundproof door curtain slats and enabling them to better meet the installation and use requirements in building decoration and industrial production.

[0021] The rubber protective layer on the inner side of the guide plate in this application acts as a buffer during the curtain's exit process, preventing surface damage caused by direct collision between the curtain and the guide plate. Simultaneously, the buffer springs inside the guide plate and the buffer springs between the guide plate and the stop block effectively reduce the impact force on the curtain during its fall, preventing deformation or damage due to the impact.

[0022] The discharge port at the front end of the forming device in this application is aligned horizontally and appropriately with the outlet of the curtain slat mold, allowing the curtain slats to fall directly from the mold outlet along the inside of the discharge port onto the guide plate. This design ensures smooth discharge of the curtain slats during production, reducing production stoppages caused by obstructed discharge. The guide plate has a smooth, curved surface, effectively guiding the falling curtain slats and allowing them to slide smoothly into the collection device. This process requires minimal manual intervention, improving the collection efficiency of the curtain slats and thus enhancing the overall production efficiency.

[0023] This application allows for the production of slats of different specifications by adjusting the position of the guide plate. The adjusting rod at the bottom of the guide plate can move within the groove and channel of the support frame. After adjustment, it is fixed using locking kits and stabilizing pads. This flexible adjustment mechanism enables the equipment to quickly switch between producing slats of different lengths, reducing the time spent changing molds or equipment and improving equipment utilization and production efficiency.

[0024] The support frame of this application is securely connected to the outer wall of the device body via a fixing plate and bolts, providing stable support for the discharge plate. Simultaneously, the stop block at the bottom of the guide plate cooperates with the stabilizing sleeve on the mounting bracket at the bottom of the discharge port, ensuring the stability of the guide plate when subjected to the impact force of the falling curtain. The buffer spring acts as a cushion during the curtain's fall, reducing the impact force on the guide plate and other related components, thereby reducing wear on these components caused by strong impacts. Furthermore, a rubber stabilizing pad is used at the contact point between the locking kit and the bottom of the support frame, increasing the friction of the contact surface; the elasticity of the rubber also helps reduce wear caused by minor vibrations during equipment operation.

[0025] The adjustment of the output plate position in this application is relatively simple. The operator only needs to loosen the locking mechanism, move the adjusting rod to the desired position, and then tighten the locking mechanism to complete the adjustment. This intuitive and convenient operation reduces the skill requirements for operators and facilitates flexible adjustment of equipment parameters according to actual needs during production.

Example

[0040] Please see Figure 1-8 A soundproof door curtain slat forming machine includes a device body 1, a forming device 2 installed on the device body 1, a curtain slat mold 3 inside the forming device 2 for forming curtain slats, guide plates 4 symmetrically provided at both ends of the outlet of the curtain slat mold 3, a discharge port 701 opened at the front end of the forming device 2 for discharging the curtain slats, support frames 5 symmetrically provided on both sides of the front end of the forming device 2, the guide plates 4 can move back and forth relative to the support frames 5, and a collection frame 101 is placed on the device body 1, the collection frame 101 being located directly below the discharge port 701.

[0041] The soundproof door curtain slat forming machine of this application is mainly composed of a device body 1, a forming device 2, a curtain slat mold 3, an output plate 4, a support frame 5, a guide plate 6, a discharge port 701, and other components. The following is a detailed description of its structure and working principle.

[0042] (a) Equipment assembly

[0043] Install the forming device 2 onto the device body 1, ensuring a secure connection. The forming device 2 is used to form materials, and it contains a curtain mold 3.

[0044] The curtain slat mold 3 is installed inside the forming device 2, and its shape and size are designed according to the specifications of the required soundproof door curtain slats. The rear opening of the mold is used for material input, and the material is formed inside the mold by methods such as cold pressing.

[0045] The outlet ends of the curtain slat mold 3 are symmetrically equipped with guide plates 4. The length of the guide plates 4 is designed according to the length of the curtain slat to ensure that the movement of the curtain slat is effectively limited when it falls. A protective layer of rubber material 401 is glued to the inner contact surface of the guide plates 4 to prevent damage to the material due to collision during discharge.

[0046] Setting of discharge port 701 and related components

[0047] A discharge port 701, adapted to the width of the slat, is opened at the front end of the forming device 2. The discharge port 701 is on the same horizontal line as the outlet of the slat mold 3 and is located directly in front of it. In this way, the slats separated from the opening of the slat mold 3 can fall directly along the inside of the discharge port 701.

[0048] Symmetrical recessed mounting grooves 702 are formed on both sides of the rear end inside the discharge port 701 for mounting the rotating rod structure 7. The two ends of the rotating rod structure 7 are fastened to the recessed mounting grooves 702 with bolts, which facilitates subsequent disassembly.

[0049] Installation of guide plate 6 and its related components

[0050] On the device body 1, a guide plate 6 is placed directly below the discharge port 701. A buffer spring 601 is movably installed inside the guide plate 6. Its surface is smooth and has an arc facing the inside of the collection frame 101 placed on the device body 1 for collecting materials, and is used to guide the curtain falling from the discharge port 701.

[0051] A stop 602 is provided at the bottom rear end of the guide plate 6, and a buffer spring 601 is provided between the stop 602 and the guide plate 6. The bottom of the discharge port 701 is connected to the mounting bracket 604 by bolts. The mounting bracket 604 is connected to the stabilizing sleeve 603, and the stop 602 is inserted into the stabilizing sleeve 603 to ensure the stability of the guide plate 6 and facilitate subsequent disassembly.

[0052] Connection between support frame 5 and guide plate 4

[0053] Support frames 5 are symmetrically arranged on both sides of the front end of the molding device 2. The sides of the support frames 5 are connected to the outer wall of the device body 1 by bolts through fixing plates 503, which facilitates disassembly.

[0054] The support frame 5 has a longitudinal channel 501 and a transverse channel 502 inside, and an adjusting rod 402 is fixedly connected to the bottom of the guide plate 4. The adjusting rod 402 can move along the channel 502 into the channel 501 to move back and forth to adjust the position of the guide plate 4.

[0055] The adjusting rod 402 has a thread at one end that passes through the slot 501 and the channel 502, and the locking kit 403 is connected to the thread by rotation. The top of the locking kit 403 has a rubber stabilizing pad 404. When the locking kit 403 is rotated and fastened to the bottom of the support frame 5 and comes into contact with it, the friction of the contact surface can be increased, making the position of the guide plate 4 more stable.

[0056] (II) Material Selection

[0057] Protective layer 401 and stabilizing pad 404

[0058] The protective layer 401 and the stabilizing pad 404 are made of rubber. Rubber has good elasticity and cushioning properties, which can effectively prevent the curtain from being damaged by collision with the guide plate 4, and increase the friction when the locking kit 403 contacts the support frame 5, ensuring a stable connection.

[0059] 601 buffer spring

[0060] The buffer spring 601 should be made of a spring material with a suitable elastic coefficient. When the curtain falls onto the guide plate 6 and slides into the collection frame 101, the buffer spring 601 can buffer the impact of the curtain and prevent damage to the curtain.

[0061] Other metal components

[0062] The main metal components, including the device body 1, forming device 2, curtain slat mold 3, guide plate 4, and support frame 5, can be made of high-strength steel. The steel has sufficient strength and rigidity to withstand the pressure and stress during operation, ensuring the stability and service life of the equipment.

[0063] Working principle

[0064] (a) Shaping and Cutting of Curtain Slats

[0065] The material is fed in through the opening at the rear of the curtain mold 3, and through forming processes such as cold pressing, the metal sheet and other materials are formed into a soundproof door curtain within the curtain mold 3.

[0066] The cutting device located in the center of the forming device 2 breaks the formed curtain slab.

[0067] (II) Curtain slat outlet and restriction

[0068] The cut slats are exited from the slat mold 3. Since the slats may experience stress and deformation during the forming and cutting process, the guide plate 4 plays a crucial role at this time. The guide plate 4 is symmetrically arranged at both ends of the slat mold 3 exit, and its length is designed according to the length of the slats to restrict the movement of the slats in the horizontal direction.

[0069] When the slats fall from the mold exit, the guide plate 4 provides support and guidance on both sides of the slats, preventing them from shifting left or right due to their own weight or other external forces. The protective layer 401 on the inner side of the guide plate 4 not only prevents the slats from being damaged by direct collision with the guide plate 4, but also reduces the friction between the slats and the guide plate 4 to a certain extent, allowing the slats to be smoothly discharged from the mold exit.

[0070] The limiting effect of the guide plate 4 on the slats is based on its position and structural design. The installation position of the guide plate 4 is closely matched with the outlet of the slat mold 3, and the length of the guide plate 4 is sufficient to cover the possible range of movement of the slats in the horizontal direction.

[0071] From a mechanical perspective, when the slats are subjected to external forces such as lateral forces generated by airflow or the slats' own inertial forces attempting to deflect them to the left or right, the guide plate 4 provides a restraining force opposite to the direction of deflection. This restraining force is transmitted to the slats through the contact between the guide plate 4 and the slats, keeping the slats on the correct guide path. Simultaneously, the stiffness and strength of the guide plate 4 ensure that it will not deform under the pressure and potential impact forces of the slats, thus effectively limiting the movement of the slats at all times.

[0072] (iii) Guiding curtain slats from falling off

[0073] The slats separated from the slat mold 3 fall directly into the discharge port 701 at the front end of the forming device 2. The discharge port 701 is on the same horizontal line as the outlet of the slat mold 3 and is located directly in front of it, ensuring that the slats can smoothly enter the discharge port 701.

[0074] A guide plate 6, which is movably installed inside the discharge port 701, guides the falling slats. The guide plate 6 has a smooth surface and is curved towards the collection frame 101, allowing the slats to slide smoothly into the collection frame 101 for centralized collection.

[0075] (iv) Buffering and stabilization mechanisms

[0076] When the curtain slats fall onto the guide plate 6, the buffer spring 601 inside the guide plate 6 acts as a buffer to reduce the impact force on the curtain slats and prevent damage to them.

[0077] The stop block 602 at the bottom rear end of the guide plate 6 is inserted into the stabilizing sleeve 603 connected to the mounting bracket 604 at the bottom of the discharge port 701 to ensure the stability of the guide plate 6. At the same time, the buffer spring 601 between the stop block 602 and the guide plate 6 further enhances the buffering effect.

[0078] Five-way plate 4 position adjustment

[0079] For curtain slats of different specifications, the position of the guide plate 4 can be adjusted to meet production requirements. The adjusting rod 402 at the bottom of the guide plate 4 can move along the channel 502 inside the support frame 5 and enter the groove 501 to move back and forth.

[0080] After adjusting the position, the locking device 403 on the adjusting rod 402 is rotated to secure it to the bottom of the support frame 5. The rubber stabilizing pad 404 on the top of the locking device 403 increases the friction with the bottom of the support frame 5, making the position of the guide plate 4 more stable and ensuring that the movement direction of the curtain can be accurately limited during the curtain slat outgoing process.

[0081] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
