Description

Technical Field

[0001] This application relates to the field of plastic processing technology, and in particular to a nylon 6 chip shaping oven for the production of high-strength transparent monofilament. Background Technology

[0002] Nylon 6, also known as polyamide 6, has similar chemical and physical properties to nylon 66; however, it has a lower melting point and a wider processing temperature range.

[0003] In related technologies, nylon 6 slices are placed in an oven for heating and shaping. The oven has a hinged door that can be opened and closed. To ensure the stability of the door after it is closed, existing ovens usually have a locking mechanism set at a position away from the hinge axis of the door to limit the rotation of the door.

[0004] However, the existing locking mechanism, located on the outside of the door's hinge axis, results in a significant amount of external space being occupied. Utility Model Content

[0005] This application provides a nylon 6 chip shaping oven for high-strength transparent monofilament production, which can reduce the space occupied by the door locking mechanism when it is arranged.

[0008] The high-strength transparent monofilament production nylon 6 chip shaping oven provided in this application restricts the rotation of the door around the hinge axis through a locking mechanism formed by the insertion and cooperation of the positioning post and the positioning hole. Thus, by arranging the positioning post inside the hinge axis, the space occupied by the door can be reduced compared with the prior art.

[0009] In some embodiments, the axis of the positioning post is kept parallel to the axis of the hinge axis.

[0010] In some embodiments, a spring is compressed at the inner end of the positioning post.

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description of this application is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0027] Nylon 6, also known as polyamide 6, has similar chemical and physical properties to nylon 66; however, it has a lower melting point and a wider processing temperature range.

[0028] In related technologies, nylon 6 slices are placed in an oven for heating and shaping. The oven has a hinged door that can be opened and closed. To ensure the stability of the door after it is closed, existing ovens usually have a locking mechanism set at a position away from the hinge axis of the door to limit the rotation of the door.

[0029] However, the existing locking mechanism, located on the outside of the door's hinge axis, results in a significant amount of external space being occupied.

[0030] Based on the above considerations, this application provides a nylon 6 chip shaping oven for high-strength transparent monofilament production, which can reduce the space occupied by the door locking mechanism when it is arranged.

[0031] The specific implementation of this application will be described in detail below with reference to specific embodiments.

[0032] Please see Figures 1-4 This application provides a high-strength transparent monofilament production nylon 6 chip shaping oven, including a door 20 hinged to the main body 10 of the oven, a hinge shaft 12 on the main body 10 and a shaft hole 211 on the door 20, an eccentrically arranged positioning post 13 passing through the hinge shaft 12, and the positioning post 13 and the positioning hole 212 at the bottom of the shaft hole 211 are inserted into each other.

[0033] The main body 10 defines a drying chamber and has a heating module for heating and drying nylon 6 slices placed inside the drying chamber.

[0034] The door 20 is hinged to the door opening on the main body 10 of the box. When the door 20 is opened, the nylon 6 slices can be put into the drying chamber through the door opening. When the door 20 is closed, the door opening will be sealed, thus forming a closed space in the drying chamber.

[0035] The hinge shaft 12 is provided on the box body 10, and the shaft hole 211 is provided on the door 20. The hinge shaft 12 is rotatably inserted into the shaft hole 211, so that the door 20 and the box body 10 form a hinge connection. The door 20 rotates around the hinge shaft 12 to realize the opening and closing function.

[0036] The positioning pin 13 passes through the insertion hole 121 on the end face of the hinge shaft 12, and the positioning pin 13 can slide inside the insertion hole 121 and extend to the outside of the end face of the hinge shaft 12.

[0037] The positioning hole 212 is opened on the bottom of the shaft hole 211, and the positioning hole 212 allows the positioning pin 13 to be inserted into it. Since the positioning pin 13 is eccentrically arranged with the axis of the hinge shaft 12, the rotation of the door 20 relative to the hinge shaft 12 can be restricted when the positioning pin 13 is inserted into the positioning hole 212.

[0038] It should be noted that when the door 20 is completely closed, the positioning pin 13 and the positioning hole 212 are coaxial, and the positioning pin 13 can be inserted into the positioning hole 212, thereby locking the door 20.

[0039] Before the door 20 is fully closed, the positioning post 13 and the positioning hole 212 are misaligned, and the outer end of the positioning post 13 is blocked by the bottom of the shaft hole 211.

[0040] The high-strength transparent monofilament production nylon 6 chip shaping oven provided in this application restricts the rotation of the door 20 around the hinge axis 12 by a locking mechanism formed by the insertion and cooperation of the positioning post 13 and the positioning hole 212. Thus, by arranging the positioning post 13 inside the hinge axis 12, the space occupied by the door can be reduced compared with the prior art.

[0041] Please see Figures 1-4 In some embodiments, the axis of the positioning post 13 is kept parallel to the axis of the hinge shaft 12.

[0042] The axis of the positioning pin 13 is parallel to the axis of the hinge shaft 12 and is eccentrically arranged. The axis of the positioning hole 212 is also parallel to the axis of the shaft hole 211 and is eccentrically arranged.

[0043] Among them, the insertion hole 121 on the end face of the hinge shaft 12 is a circular hole, the positioning post 13 is adapted to the shape of the insertion hole 121, the positioning post 13 is configured as a cylinder, the outer diameter of the positioning post 13 is equal to the diameter of the insertion hole 121, and the positioning hole 212 is constructed as a circular hole adapted to the size of the positioning post 13.

[0044] Please see Figures 1-4 In some embodiments, the inner end of the positioning post 13 is compressed with a spring 14.

[0045] The spring 14 is compressed between the inner end face of the positioning post 13 and the bottom of the insertion hole 121. The spring 14 exerts a pushing force on the positioning post 13 toward the shaft hole 211, so that when the door 20 is fully closed and the positioning post 13 is aligned with the positioning hole 212, the positioning post 13 can automatically insert into the positioning hole 212 under the push of the spring 14, thereby locking the position of the door 20 and ensuring the stability of the door 20 after it is closed.

[0046] Please see Figures 1-4 In some embodiments, a slider 16 passing through the hinge shaft 12 is fixed to the positioning post 13.

[0047] The slider 16 passes through and extends out of the hinge shaft 12. The slider 16 can drive the positioning pin 13 to move, which makes it easy to move the positioning pin 13 from the inside of the positioning hole 212, thereby releasing the lock on the door 20 and allowing the door 20 to be opened smoothly.

[0048] Please see Figures 1-4 In some embodiments, a locking rod 15, whose inner end is inserted into the slider 16, is screwed onto the positioning post 13.

[0049] The locking rod 15 and the positioning post 13 are arranged coaxially and are threaded together. After the locking rod 15 is screwed in axially, its inner end is inserted into the hole on the slider 16, thereby restricting the slider 16 to the positioning post 13.

[0050] As an example, the slider 16 is arranged radially along the positioning post 13.

[0051] Please see Figures 1-4 In some embodiments, the hinge shaft 12 is formed on the end face of the fixed block 11.

[0052] The fixing block 11 is fixed to the box body 10. The fixing blocks 11 are symmetrically arranged on both sides of the door 20. The hinge shaft 12 is formed on the opposite end face of the two fixing blocks 11. The fixing block 11 is provided with a groove 111 for engaging the slider 16. The extension direction of the groove 111 is parallel to the axis of the hinge shaft 12. The outer end of the slider 16 is provided with a limiting plate 161 that fits against the fixing block 11. Pushing the limiting plate 161 can drive the slider 16 to move along the groove 111, thereby driving the positioning post 13 to move along the insertion hole 121.

[0053] It should be noted that the slider 16 is first inserted into the insertion hole 121 via the slide groove 111, and then inserted into the positioning post 13 via the limiting hole 131 on the positioning post 13. The limiting hole 131 is configured as a rectangular hole and is adapted to the size of the positioning post 13.

[0054] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
