Description

Technical Field

[0001] This utility model relates to the field of adhesive strip processing technology, and in particular to an extrusion device for door and window adhesive strips. Background Technology

[0002] A soft and hard rubber strip extruder is a type of machinery used to manufacture various plastic or rubber products, especially for producing long strip products such as sealing strips and profiles. These machines can process materials of varying hardness, such as soft rubbers (e.g., EPDM, silicone rubber) and hard plastics (e.g., PVC), hence the name "soft and hard rubber strip extruder." The working principle of an extruder is to melt the raw material (usually granular or powdered plastic or rubber) under heat and pressure, and then extrude it through a die of a specific shape to form the desired product. In the field of door and window sealing strip production, with the continuous improvement of quality requirements for doors and windows in the construction industry, the quality of the sealing strips is crucial. Existing door and window sealing strip extrusion equipment faces many problems affecting product quality during operation.

[0003] The inventors believe that the following defects often exist: when the processing machine is in use or idle, a large amount of dust falls into the feeding hopper, causing the raw materials in the feeding hopper to be covered and contaminated by dust and impurities, resulting in the contaminated raw materials entering the processing machine, thus causing the processed products to be of substandard quality; therefore, in order to address the above problems, a door and window sealing strip extrusion device is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology where the raw materials in the feeding hopper are contaminated, and the contaminated raw materials enter the processing machine, resulting in substandard product quality. Therefore, this invention proposes a door and window sealing strip extrusion device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a door and window sealing strip extrusion device, comprising a processing machine, wherein a feeding bin is connected to the upper surface of the processing machine, a discharge head is installed on one side of the processing machine, a dustproof device is provided on the arc surface of the feeding bin, the dustproof device includes a support frame, the support frame is fixedly connected to the arc surface of the feeding bin, a rotating rod is fixedly connected to the inner surface of the support frame, a connecting plate is rotatably connected to the arc surface of the rotating rod, a dustproof plate is fixedly connected to one side of the connecting plate, a rubber stopper is fixedly connected to one side of the dustproof plate, and the arc surface of the rubber stopper is slidably connected to the feeding bin.

[0006] The effect achieved by the above-mentioned components is as follows: by setting up a dustproof device, the feeding bin is protected from dust, which prevents a large amount of dust from falling into the feeding bin when the processing machine is in use or idle. This would prevent the raw materials in the feeding bin from being covered and contaminated by dust and impurities, thus contaminating the raw materials in the feeding bin and allowing the contaminated raw materials to enter the processing machine, resulting in substandard product quality after processing. This improves the protective performance of the device.

[0007] Preferably, a fixing rod is fixedly connected to the arc surface of the feeding hopper, an operating plate is slidably connected to the arc surface of the fixing rod, an insertion rod is fixedly connected to one side of the operating plate, and a slot is provided on the arc surface of the dustproof plate.

[0008] The effect achieved by the above-mentioned components is to fix and limit the dustproof plate, thus preventing the dustproof plate from shaking due to the vibration generated during the operation of the processing machine, which would force the rubber plug to open and reduce the dustproof effect of the feeding hopper.

[0009] Preferably, a limiting plate is fixedly connected to the end of the fixing rod away from the feeding bin, and the size of the insertion rod is adapted to the size of the dustproof plate slot.

[0010] The effect achieved by the above components is that the limiting plate restricts the maximum sliding distance of the operating plate on the arc surface of the fixed rod, thus preventing the operating plate from detaching from the arc surface of the fixed rod due to excessive pulling force when the operator pulls it.

[0011] Preferably, a first spring is fitted onto the arc surface of the fixing rod, and the two ends of the first spring are fixedly connected to the operating plate and the feeding bin, respectively.

[0012] The effect achieved by the above components is that the first spring improves the stability of the insertion rod when it limits the dust cover.

[0013] Preferably, the arc surface of the rotating rod is fitted with two torsion springs, and the two ends of the torsion springs are respectively fixedly connected to the support frame and the connecting plate.

[0014] The effect achieved by the above components is that the torsion spring automatically opens the rubber plug, thereby reducing the number of steps required for the operator to operate the device and improving the operator's work efficiency.

[0015] Preferably, the surface of the discharge head has two mounting grooves, and the surfaces of the two discharge head mounting grooves are provided with a filter device. The filter device includes two connecting blocks, which are slidably connected to the surfaces of the two discharge head mounting grooves respectively. A filter plate is fixedly connected to the side of the two connecting blocks that are close to each other. A strip plate is fixedly connected to the surface of the discharge head mounting groove. A slide rod is slidably inserted into the strip plate. A semi-circular block is fixedly connected to one end of the slide rod. The semi-circular block is slidably connected to the surface of the connecting block. A second spring is sleeved on the arc surface of the slide rod. The two ends of the second spring are fixedly connected to the strip plate and the slide rod respectively.

[0016] The effect achieved by the above-mentioned components is as follows: by setting up a filtration device, the processed products in the discharge head are filtered, which avoids the presence of a large number of impurities in the raw materials fed into the feeding hopper. Excessive impurities are discharged from the discharge head with the raw materials after being heated by the processing machine, thereby reducing the quality of the products and improving the practicality of the device.

[0017] Preferably, an arc-shaped block is fixedly connected to the surface of the connecting block, and the size of the arc-shaped block is adapted to the size of the discharge head mounting groove.

[0018] The effect achieved by the above-mentioned components is that the arc-shaped block prevents the products discharged from the discharge head from entering the installation groove of the discharge head, thus avoiding a large number of processed products from entering the installation groove of the discharge head and causing the slide bar to be blocked.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] 1. In this utility model, by setting up a dustproof device, the dustproof effect of the feeding bin is achieved, which avoids a large amount of dust falling into the feeding bin when the processing machine is in use or idle, causing the raw materials in the feeding bin to be covered and contaminated by dust and impurities, resulting in the contaminated raw materials entering the processing machine, thus causing the processed product to be of substandard quality, thereby improving the protective performance of the device.

[0021] 2. In this utility model, by setting up a filtration device, the product processed in the discharge head is filtered, which avoids the presence of a large number of impurities in the raw materials fed into the feeding hopper. Excessive impurities are discharged from the discharge head with the raw materials after being heated by the processing machine, thereby reducing the product quality and improving the practicality of the device.

[0030] Reference Figure 1 As shown, this utility model provides a technical solution: a door and window sealing strip extrusion device, including a processing machine 1. The upper surface of the processing machine 1 is connected to a feeding bin 2, and a discharge head 3 is installed on one side of the processing machine 1. The arc surface of the feeding bin 2 is provided with a dustproof device 4. By setting the dustproof device 4, the feeding bin 2 is protected from dust, preventing a large amount of dust from falling into the feeding bin 2 when the processing machine 1 is in use or idle. This would cause the raw materials in the feeding bin 2 to be covered and contaminated by dust and impurities, resulting in contamination of the raw materials in the feeding bin 2. The contaminated raw materials would then enter the processing machine 1, causing the processed product to be substandard. This improves the protective performance of the device. The surface of the discharge head 3 has two mounting grooves, and the surfaces of the two mounting grooves of the discharge head 3 are provided with a filter device 5. By setting the filter device 5, the processed product in the discharge head 3 is filtered, preventing the raw materials fed into the feeding bin 2 from containing a large amount of impurities. Excessive impurities would be discharged from the discharge head 3 with the raw materials after being heated by the processing machine 1, thus reducing the product quality and improving the practicality of the device.

[0031] The specific setup and function of its dustproof device 4 and filter device 5 will be explained below.

[0032] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in this embodiment: the dustproof device 4 includes a support frame 401, which is fixedly connected to the arc surface of the feeding bin 2. A rotating rod 402 is fixedly connected to the inner surface of the support frame 401. A connecting plate 403 is rotatably connected to the arc surface of the rotating rod 402. A dustproof plate 404 is fixedly connected to one side of the connecting plate 403. A rubber plug 405 is fixedly connected to one side of the dustproof plate 404. The arc surface of the rubber plug 405 is slidably connected to the feeding bin 2. A fixing rod 406 is fixedly connected to the arc surface of the feeding bin 2. An operating plate 407 is slidably connected to the arc surface of the fixing rod 406. An insertion rod 408 is fixedly connected to one side of the operating plate 407. A slot is provided on the arc surface of the dustproof plate 404. When the worker inserts the rubber plug 405... 5. After inserting the rod into the feeding bin 2, press the operating plate 407 to slide it on the arc surface of the fixed rod 406. At the same time, the operating plate 407 drives the insertion rod 408 to move until the insertion rod 408 is inserted into the slot of the dustproof plate 404. At this time, the dustproof plate 404 is fixed and limited, which prevents the dustproof plate 404 from shaking due to the vibration generated during the operation of the processing machine 1. This would force the rubber plug 405 to open, thereby reducing the dustproof effect of the feeding bin 2. The end of the fixed rod 406 away from the feeding bin 2 is fixedly connected to the limiting plate 409. The size of the insertion rod 408 is adapted to the size of the slot of the dustproof plate 404. When the operator pulls the operating plate 407, When the operating plate 407 slides on the arc surface of the fixed rod 406, the limiting plate 409 effectively limits the maximum sliding distance of the operating plate 407 on the arc surface of the fixed rod 406, preventing the operating plate 407 from detaching from the arc surface of the fixed rod 406 due to excessive pulling force when the operator pulls it. A first spring 410 is fitted onto the arc surface of the fixed rod 406, with both ends of the first spring 410 fixedly connected to the operating plate 407 and the feeding bin 2, respectively. When the operator releases the operating plate 407, the rebound force of the first spring 410 causes the operating plate 407 to slide on the arc surface of the fixed rod 406, simultaneously driving the insertion rod 408 to move until the insertion rod 408 inserts into the anti-slip device. Inside the slot of the dust plate 404, the first spring 410 improves the stability of the insertion rod 408 when it limits the dust plate 404. Two torsion springs 411 are sleeved on the arc surface of the rotating rod 402. The two ends of the torsion springs 411 are fixedly connected to the support frame 401 and the connecting plate 403, respectively. When the operator releases the insertion rod 408 from limiting the dust plate 404, the torque of the torsion springs 411 drives the connecting plate 403 to rotate on the arc surface of the rotating rod 402. The connecting plate 403 drives the dust plate 404 to rotate, and the dust plate 404 drives the rubber plug 405 to disengage from the feeding bin 2. At this time, the torsion springs 411 achieve the effect of automatically opening the rubber plug 405, so as to reduce the operator's operation steps and improve the operator's work efficiency.

[0033] Reference Figure 6 and Figure 7 As shown, specifically, the filter device 5 includes two connecting blocks 51, which are slidably connected to the surfaces of the mounting slots of the two discharge heads 3 respectively. A filter plate 52 is fixedly connected to one side of the two connecting blocks 51 that is close to each other. A strip plate 53 is fixedly connected to the surface of the mounting slot of the discharge head 3. A slide rod 54 is slidably inserted in the strip plate 53. A semi-circular block 55 is fixedly connected to one end of the slide rod 54. The semi-circular block 55 is slidably connected to the surface of the connecting block 51. A second spring 56 is sleeved on the arc surface of the slide rod 54. The two ends of the second spring 56 are fixedly connected to the strip plate 53 and the slide rod 54 respectively. An arc-shaped block 57 is fixedly connected to the surface of the connecting block 51. The size of the arc-shaped block 57 is adapted to the size of the mounting slot of the discharge head 3. At this time, the arc-shaped block 57 achieves the effect of blocking the product discharged from the discharge head 3 from entering the mounting slot of the discharge head 3, thus avoiding the situation where a large number of processed products enter the mounting slot of the discharge head 3, causing the slide rod 54 to be blocked.

[0034] Working principle: When dust prevention is required for the feeding hopper 2, the operator first tightly inserts the rubber plug 405 into the feeding hopper 2. At this time, the dustproof plate 404 adheres to the surface of the feeding hopper 2, initially constructing a dustproof barrier. Then, the operator presses the operating plate 407. Guided by the fixed rod 406, the operating plate 407 slides along its arc surface, driving the insertion rod 408 to move and insert into the slot of the dustproof plate 404, reinforcing the dustproof plate 404 from the side and preventing the dustproof plate 404 from shaking due to the vibration of the processing machine 1. This ensures that the rubber plug 405 stably seals the feeding hopper 2, guaranteeing a good dustproof effect. During this process, the limiting plate 409 on the fixed rod 406 constantly limits the sliding distance of the operating plate 407, preventing the operating plate 407 from detaching from the fixed rod 406 due to improper operation, ensuring the safe operation of the device. In daily use, the first spring 410 sleeved on the fixed rod 406 plays an important role. When the operator releases the control panel 407, the first spring 410 pushes the control panel 407 with its rebound force, causing the insertion rod 408 to be precisely inserted into the slot of the dustproof plate 404 again, continuously maintaining the stable limit on the dustproof plate 404 and improving the reliability of the device operation. When it is necessary to open the feeding bin 2, the operator releases the limit on the dustproof plate 404 by the insertion rod 408, and the torsion spring 411 sleeved on the rotating rod 402 responds immediately. The two ends of the torsion spring 411 are connected to the support frame 401 and the connecting plate 403 respectively. The torque generated by it drives the connecting plate 403 to rotate, thereby causing the dustproof plate 404 to automatically disengage the rubber plug 405 from the feeding bin 2, completing the convenient opening action, reducing manual operation procedures, improving work efficiency, and ensuring the dustproof effect of the feeding bin 2 while taking into account the safety, stability and convenience of operation.

[0035] Two connecting blocks 51 slide on the surface of the discharge head 3 mounting groove, and the filter plate 52 fixed inside them constitutes the main filtration structure. When the product is discharged from the discharge head 3, it will pass through the filter plate 52. The filter plate 52 can block impurities mixed in the raw materials, thereby filtering the product and preventing impurities from affecting the product quality. In terms of installation and maintenance, a sliding rod 54 is inserted into the strip plate 53 on the surface of the discharge head 3 mounting groove. The semi-circular block 55 at one end of the sliding rod 54 is slidably connected to the surface of the connecting block 51, and the sliding rod 54 is fitted with a second spring 56. When installing the device, push the connecting block 51 to slide into the discharge head 3 mounting groove. The semi-circular block 55 slides on the surface of the connecting block 51 and compresses the second spring 56. After the connecting block 51 is in place, the elastic force of the second spring 56 pushes the slide rod 54, causing the semi-circular block 55 to lock the connecting block 51, thus fixing the device in place. When disassembly and maintenance are required, the elastic force of the second spring 56 is overcome to pull the slide rod 54, causing the semi-circular block 55 to disengage from the connecting block 51. The connecting block 51 and the filter plate 52 can then slide out of the installation groove of the discharge head 3. In addition, the arc-shaped block 57 fixed on the surface of the connecting block 51 is adapted to the size of the installation groove of the discharge head 3. During the process of the product being discharged from the discharge head 3, the arc-shaped block 57 can effectively prevent the product from entering the installation groove of the discharge head 3, avoiding the accumulation of product in the installation groove and hindering the movement of the slide rod 54, ensuring stable operation of the device and ensuring that the filtration function continues to play its role.
