Description

Technical Field

[0001] This utility model relates to the field of mold accessories technology, and in particular to a pull rod device for a waterproof cap. Background Technology

[0002] A waterproof cap is a type of cap made of polyethylene material that has undergone high-energy ion radiation treatment. Waterproof caps have high mechanical strength, aging resistance, resistance to environmental stress cracking, good sealing performance, and a long service life. During the production process of waterproof caps, after the mold is opened, the waterproof cap rod needs to be removed from the waterproof cap to facilitate subsequent processing operations.

[0003] Currently, most companies use manual extraction, which has many drawbacks. On the one hand, manual extraction is inefficient and cannot meet the needs of large-scale production. On the other hand, the difficulty in accurately controlling the force and angle during manual extraction can easily damage the waterproof cap rod and the waterproof cap product, leading to an increase in the product defect rate. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the existing technology. At present, most enterprises use manual extraction, which has many drawbacks. On the one hand, manual extraction is inefficient and cannot meet the needs of large-scale production. On the other hand, due to the difficulty in accurately controlling the operating force and angle during manual extraction, it is easy to damage the waterproof cap rod and the waterproof cap product, resulting in an increase in the product defect rate. Therefore, a rod extraction device for waterproof caps is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pull rod device for a waterproof cap includes a mounting plate with a sliding opening on its surface. A slider is slidably disposed within the sliding opening. Support plates are symmetrically fixedly mounted on the lower surface of the mounting plate. Driven rotating rods are symmetrically rotatably mounted on the side walls of the mounting plate. An active rotating rod is rotatably mounted on the surface of one of the support plates. Sprockets are fixedly sleeved on both the driven and active rotating rods. Chains are meshed and wound on multiple sprockets. A horizontal opening is provided on one side of the mounting plate. The surface of the chain is fixedly connected to the slider via a connecting rod. Multiple waterproof cap rods are fixedly mounted on the surface of the slider.

[0007] A drive motor is fixedly mounted on the surface of one of the support plates via a mounting component, and the output shaft of the drive motor is fixedly connected to the active rotating rod.

[0008] Preferably, the mounting component includes a U-shaped plate fixedly mounted on the surface of the support plate, and the drive motor is fixedly mounted on the surface of the U-shaped plate.

[0009] Preferably, the upper and lower walls of the slide are horizontally provided with rectangular openings, and multiple U-shaped blocks are fixedly installed on the upper and lower surfaces of the slider. A rotating shaft is horizontally rotatably installed inside the U-shaped block, and a roller is fixedly sleeved on the rotating shaft. The multiple rollers respectively roll in contact with the walls of the multiple rectangular openings.

[0010] Preferably, the surface of the chain is provided with an anti-detachment component, which is used to prevent the chain from separating from the sprocket.

[0011] Preferably, the anti-detachment component includes two connecting rods, and anti-detachment grooves are symmetrically and obliquely formed on the surface of the support plate near the chain. The ends of the two connecting rods away from the chain are respectively slidably disposed in the two anti-detachment grooves.

[0012] Preferably, a scraper ring is slidably fitted on the surface of the waterproof cap rod, two adjacent scraper rings are fixedly connected by a straight rod, and the surfaces of the two scraper rings furthest apart are fixedly connected to the mounting plate by an L-shaped rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0024] Reference Figures 1-6 A pull rod device for a waterproof cap includes a mounting plate 1. A sliding opening 2 is provided on the surface of the mounting plate 1, and a slider 3 is slidably disposed in the sliding opening 2. Support plates 4 are symmetrically fixedly installed on the lower surface of the mounting plate 1. Driven rotating rods 5 are symmetrically rotatably installed on the side wall of the mounting plate 1. A driving rotating rod 6 is rotatably installed on the surface of one of the support plates 4. A sprocket 7 is fixedly sleeved on both the driven rotating rod 5 and the driving rotating rod 6. Chains 8 are meshed and wound on multiple sprockets 7. A through opening 9 is horizontally opened on one side of the mounting plate 1. The surface of the chain 8 is fixedly connected to the slider 3 through a connecting rod. Multiple waterproof cap rods 10 are fixedly installed on the surface of the slider 3.

[0025] One of the support plates 4 has a drive motor 11 fixedly mounted on its surface by a mounting component. The mounting component includes a U-shaped plate 12 fixedly mounted on the surface of the support plate 4. The drive motor 11 is fixedly mounted on the surface of the U-shaped plate 12, and the output shaft of the drive motor 11 is fixedly connected to the active rotating rod 6.

[0026] Both forward and reverse rotation of the output shaft of the drive motor 11 can drive the chain 8 to operate, but the chain 8 operates in opposite directions.

[0027] When the drive motor 11 is started, the output shaft of the drive motor 11 rotates clockwise with the active rotating rod 6. Under the transmission action of multiple sprockets 7, the chain 8 moves the slider 3 and multiple waterproof cap rods 10 to complete the rod pulling. When the rod needs to be inserted, the output shaft of the drive motor 11 rotates counterclockwise with the active rotating rod 6, causing the chain 8 to move the slider 3 and multiple waterproof cap rods 10 to complete the rod insertion.

[0028] The upper and lower walls of the slide 2 are both horizontally provided with rectangular openings 13. Multiple U-shaped blocks 14 are fixedly installed on the upper and lower surfaces of the slider 3. A rotating shaft is horizontally rotatably installed inside the U-shaped block 14. Rollers 15 are fixedly sleeved on the rotating shaft. The multiple rollers 15 respectively roll in contact with the walls of the multiple rectangular openings 13.

[0029] The roller 15 can reduce the friction between the surface of the slider 3 and the contact surface of the sliding mouth 2, making it easier for the chain 8 to move the slider 3 when it is running, and avoiding the movement of the slider 3 due to the large friction of the contact surface.

[0030] The surface of the chain 8 is provided with an anti-detachment component, which is used to prevent the chain 8 from separating from the sprocket 7. The anti-detachment component includes two connecting rods 16. The surface of the support plate 4 near the chain 8 is symmetrically and obliquely provided with anti-detachment grooves 17. The ends of the two connecting rods 16 away from the chain 8 are respectively slidably disposed in the two anti-detachment grooves 17.

[0031] Both anti-derailment grooves 17 correspond to the position of the chain 8. One end of the connecting rod 16 can only slide within the anti-derailment groove 17, thereby preventing the chain 8 from separating from the sprocket 7.

[0032] The surface of the waterproof cap rod 10 is slidably fitted with a scraper ring 18. Two adjacent scraper rings 18 are fixedly connected by a straight rod, and the surfaces of the two scraper rings 18 that are furthest apart are fixedly connected to the mounting plate 1 by an L-shaped rod.

[0033] When the waterproof cap rod 10 is moved and pulled out, the multiple waterproof cap rods 10 will move within multiple scraping rings 18 respectively, and the surface of the waterproof cap rod 10 will slide into contact with the inner ring wall of the scraping ring 18, thereby cleaning the surface of the waterproof cap rod 10.

[0034] During the contact process between the waterproof cap rod 10 and the waterproof cap material, some debris, particles or other impurities of the waterproof cap material may adhere to the surface. If not cleaned, these impurities may be mixed into the newly produced waterproof cap during the next use, affecting the structural integrity and performance of the waterproof cap, causing defects such as holes and cracks in the waterproof cap, and reducing the waterproof effect.

[0035] Meanwhile, the surface of the removed waterproof cap rod 10 may have residual mold release agent, oil, or other chemicals. If these substances transfer to the surface of the waterproof cap, they will contaminate the waterproof cap, affect its appearance quality, and may also have an adverse effect on the assembly and bonding of the waterproof cap with other components, thus reducing the overall quality of the product.

[0036] In this invention, by starting the drive motor 11, the output shaft of the drive motor 11 rotates clockwise with the active rotating rod 6. Under the transmission action of multiple sprockets 7, the chain 8 moves the slider 3 and multiple waterproof cap rods 10, thereby completing the rod pulling. When it is necessary to insert the rod, the output shaft of the drive motor 11 rotates counterclockwise with the active rotating rod 6, causing the chain 8 to move the slider 3 and multiple waterproof cap rods 10, thereby completing the rod insertion. This can replace manual rod pulling and insertion, improving the extraction efficiency. At the same time, it can accurately control the operating force and angle, ensuring the product qualification rate.

[0037] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
