Description

Technical Field

[0001] This utility model relates to the technical field of silicone strip production, specifically the technical field of directly producing silicone strips using liquid silicone. Background Technology

[0002] Silicone strips are currently primarily made from solid silicone extrusion. Solid silicone is produced by mixing silicone base material with other additives and then undergoing a compounding process. Liquid silicone production, on the other hand, only requires mixing the two-component liquid silicone raw materials using a liquid silicone feeder before direct extrusion, eliminating the need for compounding and simplifying the production process. Furthermore, compared to solid silicone, liquid silicone products offer higher transparency and better aesthetics. However, liquid silicone has high fluidity and is prone to deformation under gravity after extrusion, affecting product performance and appearance. Therefore, liquid silicone should be vulcanized immediately after extrusion to prevent deformation due to gravity. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an adjustable-angle silicone strip extrusion device. This device can precisely and accurately adjust the position and angle of the liquid silicone extrusion equipment, bringing it as close as possible to the vulcanizing equipment. The extruded liquid silicone product can immediately fall onto the vulcanizing equipment for vulcanization, minimizing the impact of gravity on the liquid silicone product. Simultaneously, it can improve equipment utilization and increase silicone strip production efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-angle silicone strip extrusion device, comprising a silicone strip extrusion device and a position adjustment device; the silicone strip extrusion device is a tubular structure, with an extrusion nozzle at one end and a feed inlet connected to a liquid silicone feeder at the other end; the position adjustment device is used to support and install the silicone strip extrusion device, and includes a position fixing device placed on the ground, a height adjustment rod connected to the upper end of the position fixing device, an orientation adjustment device on the height adjustment rod, a horizontal adjustment rod installed in the orientation adjustment device, and the silicone strip extrusion device installed at the end of the horizontal adjustment rod via a universal adjuster.

[0005] The silicone strip extrusion device is an L-shaped tubular structure. The extrusion nozzle is detachably connected to the whole and is threadedly connected to the whole, which facilitates the replacement of extrusion nozzles of different shapes and sizes.

[0006] The position fixing device has a counterweight disc structure, and the upper part of the position fixing device has a cylindrical hole for inserting a height adjustment rod, which increases the stability of the entire device.

[0007] The orientation adjustment device includes two clamp structures. One clamp is fitted outside the height adjustment rod and locked in place by a height adjustment knob. The other clamp is fitted outside the horizontal adjustment rod and locked in place by a horizontal adjustment knob. Both clamps are provided with mounting ears. Locking screws pass through the mounting ears of the two clamps to connect and position them. The orientation adjustment device is adjusted and positioned by connecting the clamps.

[0015] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] The adjustable-angle silicone strip extrusion device consists of a silicone strip extrusion device 1 and a position adjustment device 2.

[0017] Silicone strip extrusion device 1: The feed end of the silicone strip extrusion device is connected to the discharge end of the liquid silicone feeder. The discharge end of the silicone strip extrusion device is equipped with product die holes of different specifications, which can extrude silicone strips. The silicone strip extrusion device is shaped like an "L" shaped device. The long side is called the extrusion nozzle 1-1, and the short side 1-2 is connected to the discharge end of the liquid silicone feeder by a thread.

[0018] The position adjustment device 2 consists of a position fixing device 2-1, a height adjustment rod 2-2, a horizontal adjustment rod 2-3, an orientation adjustment device 2-4, and a universal adjuster 2-5.

[0019] Position fixing device 2-1: The position fixing device is a disc. The disc is placed on a horizontal ground. The disc has a certain weight or has a counterweight inside, which can stabilize the entire adjustable angle silicone strip extrusion device.

[0020] Height Adjustment Rod 2-2: The height adjustment rod is a threaded steel pipe with its lower end connected to the position fixing device.

[0021] Horizontal Adjustment Rod 2-3: The horizontal adjustment rod is also a threaded steel pipe, with one end connected to the universal adjuster. For easy distinction, the end connected to the universal adjuster is called the head of the horizontal adjustment rod.

[0022] The orientation adjustment device 2-4 includes two clamp structures. One clamp is fitted outside the height adjustment rod 2-2 and locked in place by the height adjustment knob 2-4-1. The other clamp is fitted outside the horizontal adjustment rod 2-3 and locked in place by the horizontal adjustment knob 2-4-3. Both clamps are equipped with mounting ears. The locking screw 2-4-5 passes through the mounting ears of both clamps to connect and position them. When adjusting the position, loosen the nut of the locking screw 2-4-5. When fixing the position, tighten the nut of the locking screw 2-4-5 to fix the relative position of the two clamps.

[0023] Alternatively, other methods can be used for positioning: the orientation adjustment device 2-4 and the clamp on which the height adjustment rod 2-2 is installed are provided with a height adjustment knob 2-4-2; the orientation adjustment device 2-4 and the clamp on which the horizontal adjustment rod 2-3 is installed are provided with a horizontal adjustment knob 2-4-4; the outer surfaces of the height adjustment rod 2-2 and the horizontal adjustment rod 2-3, and the inner surface of the clamp are provided with corresponding threaded structures, and the positions of the height adjustment rod 2-2 and the horizontal adjustment rod 2-3 are adjusted by rotation; one end of the height adjustment knob 2-4-2 is exposed, and the other end is threadedly connected to the clamp and inserted into the clamp, extending towards the height adjustment rod 2-2, and the height position of the height adjustment rod 2-2 is positioned by screwing the height adjustment knob 2-4-2 inward; one end of the horizontal adjustment knob 2-4-4 is exposed, and the other end is threadedly connected to the clamp and inserted into the clamp, extending towards the horizontal adjustment rod 2-3, and the horizontal direction of the horizontal adjustment rod 2-3 is positioned by screwing the horizontal adjustment knob 2-4-4 inward.

[0024] The threaded range of the height adjusting rod 2-2 can be as large as possible, allowing for greater vertical freedom of the silicone strip extrusion device and adaptability to vulcanization equipment of various heights. Similarly, the threaded range of the horizontal adjusting rod can also be as large as possible, maximizing horizontal freedom of the silicone strip extrusion device. However, it should be noted that the longer either the vertical or horizontal adjusting rod, the more prone it is to instability. Therefore, careful attention must be paid to adjusting the equipment's center of gravity during manufacturing and use.

[0025] The horizontal universal pin can control the horizontal adjusting rod, allowing it to rotate around the vertical adjusting rod. The universal pin can also be a bolt structure, which can be loosened for adjustment and tightened for fixation.

[0026] By turning the knob to adjust the position of the silicone strip extrusion device, mechanical adjustment can be used instead of manual adjustment. This allows for precise adjustment of the position of the silicone strip extrusion device, ensuring that it is as close as possible to the vulcanizing equipment and reducing the time that liquid silicone undergoes deformation due to gravity.

[0027] The universal adjuster 2-5 includes a clamping device I2-5-1 connected to the head of the horizontal adjusting rod 2-3. The clamping device I2-5-1 is a clamping structure with a tightening bolt. The clamping device II2-5-2 includes a tubular structure and an upper clamping structure. The tubular structure is inserted into the clamping device I2-5-1 and is installed and positioned by the tightening bolt on the clamp. The clamping structure consists of two semi-ring structures with mounting ears. The semi-ring structures are connected by bolts set on the mounting ears. After the semi-ring structures are connected, they form a cylindrical space for installing the silicone strip extrusion device 1.

[0028] Clamping device II uses screws to secure the silicone strip extrusion device, accommodating various specifications and offering good practicality. Theoretically, the silicone strip extrusion device can rotate 360° using a universal adjuster. Therefore, we can place as many adjustable-angle silicone strip extrusion devices as possible within a circle with the maximum extension length of the horizontal adjusting rod as the radius, extruding more silicone strips at once, improving the utilization rate of the vulcanizing equipment and increasing silicone strip production efficiency. Even if such high flexibility cannot be achieved in practice due to some obstacles, the adjustable-angle silicone strip extrusion device still offers considerable flexibility and a wide adjustment range. Adjusting the angle of the silicone strip extrusion device relative to the horizontal plane allows the extrusion nozzle to better contact the vulcanizing equipment, reducing the time the liquid silicone is affected by gravity and preventing deformation.

[0029] Example 1:

[0030] The adjustable-angle silicone strip extrusion device includes a silicone strip extrusion unit and a position adjustment unit. It is designed to produce 10mm × 1mm silicone strips using liquid silicone, with the horizontal vulcanization unit approximately 90cm high.

[0031] The total length of the extrusion nozzle of the silicone strip extrusion device is 170mm. The outer contour of the 30mm area at the inlet end has external threads and a 5mm wide hexagonal head to facilitate the mating of the liquid silicone extrusion head with the port nut of the liquid silicone feeding device. The outer contour diameter of the extrusion nozzle body is Φ25mm. The inner contour diameter of the extrusion nozzle body is Φ18mm, and the length is 120mm. The extrusion die hole size is 10mm×1mm, with a 5mm long, rounded transition at the short side to facilitate product shaping. The transition section between the main body section and the extrusion die hole section is 15mm long, with the outer and inner contours of the extrusion end area naturally transitioning to the extrusion port end. The short side is 10cm long.

[0032] The position adjustment device includes a position fixing device, a height adjustment rod, a horizontal adjustment rod, an orientation adjustment device, and a universal adjuster. The height adjustment rod is 150cm high, the horizontal adjustment rod is 50cm long, and the clamping structure of the universal adjuster clamping device I is horizontal, securing clamping device II. Clamping device II is also horizontal in its entirety.

[0033] Change the position of the fixing device so that the distance between the height adjustment rod and the horizontal vulcanizing device is about 25cm to ensure the stability of the device's center of gravity.

[0034] Next, roughly adjust the position of each part to bring the silicone strip extrusion device close to the horizontal vulcanizing device, and then continuously adjust the height of the horizontal adjusting rod and the angle of the silicone strip extrusion device to bring the silicone strip extrusion nozzle as close as possible to the horizontal vulcanizing device.

[0035] For example:

[0036] First, make a rough adjustment: Adjust the height adjustment knob of the orientation adjustment device to loosen the connection between the orientation adjustment device and the height adjustment rod. Manually adjust the horizontal adjustment rod to about 105cm above the height adjustment rod. Then, adjust the height adjustment knob to tighten the connection between the orientation adjustment device and the height adjustment rod, and fix the orientation adjustment device and the height adjustment rod in place.

[0037] Adjust the horizontal tension knob of the orientation adjustment device to loosen the connection between the orientation adjustment device and the horizontal adjustment rod. Manually adjust the horizontal adjustment rod so that it extends about 15cm. Then adjust the horizontal tension knob again to tighten the connection between the orientation adjustment device and the horizontal adjustment rod, thus fixing the orientation adjustment device and the horizontal adjustment rod in place.

[0038] Tightening or loosening the locking screw of the rotation position adjustment device causes the horizontal adjustment rod to rotate around the height adjustment rod until the horizontal adjustment rod is parallel to the horizontal vulcanizing device.

[0039] Unscrew the bolts of the clamping structure of clamping device II, clamp the short side of the “L”-shaped silicone strip extrusion device and tighten the bolts so that the clamping structure firmly clamps the silicone strip extrusion device.

[0040] Further fine-tuning: Different die holes of the silicone strip extrusion nozzle have different product shapes. According to different shape requirements, continuously adjust the height of the horizontal adjustment rod and the angle of the universal adjuster to make the distance between the silicone strip extrusion nozzle and the horizontal vulcanizing device meet the requirements.

[0041] The extruded silicone strip at this point measures 1cm × 0.1cm.
