Description

Technical Field

[0001] This utility model relates to the field of mold head maintenance technology, specifically to a mold head maintenance bracket with angle adjustment. Background Technology

[0002] Polyester film die head maintenance brackets generally consist of two parts. First, the die head must be disassembled and separated into two parts by distance adjustment. Then, it is transferred to an angle adjustment bracket, where the angle is adjusted manually using levers and secured with bolts. This intermediate transfer increases labor and time costs. Typical angle adjustment brackets lack labor-saving designs, requiring multiple personnel, and lack angle self-locking devices, further complicating angle adjustment.

[0003] Therefore, the inventors have provided a mold head maintenance bracket with adjustable angle. Utility Model Content

[0035] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following detailed description of the embodiments and the accompanying drawings are used to exemplarily illustrate the principle of this utility model, but should not be used to limit the scope of this utility model. That is, this utility model is not limited to the described embodiments, and covers any modifications, substitutions and improvements to the parts, components and connection methods without departing from the spirit of this utility model.

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] Figure 1 This is a schematic diagram of the structure of a mold head maintenance bracket with angle adjustment provided in an embodiment of this utility model. See also: Figures 1-4 The mold head maintenance bracket may include a first bracket and a second bracket that are detachably connected. The first bracket and the second bracket are arranged opposite to each other, and both the first bracket and the second bracket include an angle adjustment handle 1, a mold head connector 2, an angle self-locking device 3, a support frame 4, and a base 5. The angle adjustment handle 1 and the angle self-locking device 3 are respectively connected to the two ends of the mold head 100 through the corresponding mold head connector 2. The angle adjustment handle 1 is used to adjust the angle of the mold head 100, and the angle self-locking device 3 is used to lock the mold head 100 after the angle is adjusted. The mold head 100 is mounted on the support frame 4. The two support frames 4, which are respectively mounted on the first bracket and the second bracket, are slidably mounted on the corresponding base 5 to adjust the distance between the two mold heads 100.

[0040] In the above embodiment, the torque is transmitted to the mold head connector 2 and the mold head 100 by rotating the angle adjustment handle 1. The mold head 100 is connected to the mold head connector 2 at the other end, and the torque is transmitted to the angle self-locking device 3. When the angle is suitable for the maintenance personnel to observe, the rotation of the angle adjustment handle 1 is stopped. At this time, the angle self-locking device 3 automatically locks the angle adjustment system.

[0041] Furthermore, such as Figure 5 As shown, the angle adjustment handle 1 includes a handle wheel 101 and a planetary gear mechanism. The handle wheel 101 drives the planetary gear mechanism to rotate, thereby outputting power to the corresponding mold head 100. The planetary gear mechanism includes an external gear ring 102, a sun gear 103, and planet gears 104. Power is input from the sun gear 103, transmitted to the planet gears 104, and then output from the planet carrier to the corresponding mold head 100. The external gear ring 102 is locked. This structure can achieve a transmission ratio between 2.5 and 5, which significantly reduces the torque applied when rotating the mold head 100, thereby increasing the torque output.

[0042] As an optional implementation method, such as Figures 6-8As shown, the angle self-locking device 3 includes an adjusting limiter 301, a limiting lever 302, an elastic element 303, an elastic element support 304, an adjusting lever 305, a limit adjuster 306, an adjuster support 307, an adjusting gear 308, a limiting lever spring 309, and a positioning plate 310. The adjusting limiter 301, the limiting lever 302, the elastic element 303, the elastic element support 304, the adjusting lever 305, and the limiting lever spring 309 are all installed on the positioning plate 310. The adjusting limiter 301 is located on one side of the limiting lever 302 and is used to limit the circumferential movement of the limiting lever 302. The two limiting levers 302 are located on opposite sides of the adjusting lever 305 to form a limiting lever assembly and are used to limit the circumferential movement of the adjusting lever 305. The two elastic elements 303 are located on opposite sides of the adjusting lever 305 and are elastically connected to the adjusting lever 305. One end of the elastic element 303 is connected to the elastic element support 304, and the other end of the elastic element 303 is connected to the adjusting lever 305. The adjusting gear 308 is used to drive the adjusting lever 305 to rotate. In the absence of external force, the limiting lever 302 cooperates with the elastic element 303 and provides a reaction force to stabilize the adjusting gear 308. Multiple limiting adjusters 306 are distributed circumferentially along the adjuster support 307, and two adjacent limiting adjusters 306 are located on both sides of a set of limiting lever assemblies. The adjuster support 307 is used to drive the limiting adjusters 306 to rotate synchronously to realize the clockwise / counterclockwise rotation of the adjusting gear 308.

[0043] Specifically, such as Figure 8 As shown, one end of the limiting lever 302 is hinged to the positioning plate 310 so that it can rotate within a certain angle range under the drive of the adjusting lever 305, thereby completing the limiting of the adjusting lever 305. The elastic element 303 can specifically be a spring. The two ends of the adjusting lever 305 are elastically supported and connected by corresponding elastic elements 303. One end of the adjusting lever 305 is limited by the limiting adjuster 306, and the other end of the adjusting lever 305 is inserted into the tooth groove of the adjusting gear 308 through the limiting adjuster 306, thereby achieving the locking and limiting of the adjusting gear 308.

[0044] Furthermore, such as Figure 7 As shown, the angle self-locking device 3 also includes a support roller 311 and a connector 312. The support roller 311 is fixedly connected to the adjuster support 307 and is used to drive the adjuster support 307 to rotate synchronously. The adjusting gear 308 is connected to the mold head 100 through the connector 312. The angle self-locking device 3 can adjust the locking direction by adjusting the position of the limit adjuster 306 through the angle adjusting support roller 311.

[0045] In one specific implementation, such as Figures 1-4As shown, both the first and second supports further include a split-distance adjustment handle 6 and a split-distance adjustment screw 7. The two split-distance adjustment screws 7 are respectively threaded through and connected to the two support frames 4 on the first and second supports. The split-distance adjustment handle 6 is installed at the end of the split-distance adjustment screw 7 and is used to rotate it to adjust the distance between the two mold heads 100. Specifically, the split-distance adjustment handle 6 includes a planetary gear transmission device (the specific structure can be referred to in the planetary gear transmission device in the angle adjustment handle 1). It uses a transmission method where power is input from the sun gear and output from the planet carrier, with the external gear ring locked. This structure can improve torque output. The split-distance adjustment screw 7 uses a ball screw structure, which reduces the frictional resistance between the split-distance adjustment screw 7 and the support frame 4 and the split-distance adjustment limiter 9.

[0046] In one specific implementation, such as Figures 1-4 As shown, both the first and second supports further include a split-distance adjustment track 8, on which the support frame 4 is slidably mounted. Both the first and second supports also include a split-distance adjustment limiter 9, which is mounted on the split-distance adjustment track 8 to limit the movement of the support frame 4. The ball bearings of the split-distance adjustment limiter 9 contact the split-distance adjustment track 8 to reduce frictional resistance. By rotating the split-distance adjustment handle 6, torque is transmitted to the split-distance adjustment screw 7, which in turn transmits torque to the support frame 4, causing the support frame 4 to move along the split-distance adjustment track 8.

[0047] In one specific implementation, such as Figures 1-4 As shown, the mold head maintenance bracket also includes a split lock 10, which is used to connect the first bracket and the second bracket into a whole. The split lock 10 uses a bolt structure to connect the maintenance bracket into a whole.

[0048] In one specific implementation, such as Figures 1-4 As shown, both the first bracket and the second bracket also include casters 11. The casters 11 are installed at the bottom of the base 5 and facilitate the movement of the entire maintenance bracket. The casters 11 can also have a self-locking function.

[0049] It should be clarified that the various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments. This utility model is not limited to the specific steps and structures described above and shown in the figures. Furthermore, for the sake of brevity, detailed descriptions of known methods and techniques are omitted here.

[0050] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art without departing from the scope of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this application should be included within the scope of the claims of this application.
