Description

Technical Field

[0001] The present application relates to the technical field of film stretching equipment, and in particular to an amplitude modulation position indicating device for film production equipment. Background Art

[0002] When the film production equipment is modulating, a position indicator (meter) needs to be installed on the modulation side to indicate the current width parameters of the film.

[0003] However, the current installation of the position indicator is based on the transmission shaft passing through the oven, and the driving gear is installed on the transmission shaft. However, the transmission shaft is a cantilever structure, and the rotation will be eccentric, so the driving gear will also be eccentric. Then, the shaft of the driven gear is connected to the shaft of the position indicator, and the driven gear is meshed with the driving gear. The position of the driven gear is fixed. When the driving gear rotates eccentrically, the driven gear will not move up and down with the driving gear. When the distance between the driving gear and the driven gear is large, it is easy to cause the meshing point of the driven gear to be squeezed or disengaged, which will cause frequent failures of the position indicator. In addition, since the existing transmission shaft passes through the inside of the oven and will have a high temperature, the heat inside the oven is directly transferred to the position indicator, which is easy to cause the position indicator to overheat and be damaged.

DETAILED DESCRIPTION

[0022] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the embodiments of the present application, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is for the convenience of description, and the specific implementation of the present application should not be construed as any limitation, and the various embodiments can be combined with each other and quoted from each other without contradiction.

[0023] The present application embodiment provides a thin film production equipment amplitude modulation position indicating device, please refer to Figure 1-Figure 3 As shown, it includes a bottom plate 1, a mounting base plate 2, a position indicator 3 and a gear transmission member. The bottom plate 1 is fixedly mounted on the side of the oven, and a transmission shaft 10 passing through the inside of the oven passes through the bottom plate 1, and a clearance hole 12 is provided at the middle position of the bottom plate 1, and the transmission shaft 10 passes through the clearance hole 12, so that the transmission shaft 10 can rotate eccentrically in the clearance hole 12. The mounting base plate 2 is slidably connected to the side of the bottom plate 1 away from the oven, and the transmission shaft 10 extends to pass through the mounting base plate 2, and can drive the mounting base plate 2 to slide on the bottom plate 1 during the eccentric rotation process; the gear transmission member is arranged on the mounting base plate 2, and is used to indirectly connect the position indicator 3 with the transmission shaft 10.

[0024] In this embodiment, a mounting base plate 2 that can be slid up and down is installed on the base plate 1, and a gear transmission part is used to indirectly connect the position indicator 3 to the transmission shaft 10. Then, the high temperature brought by the transmission shaft 10 will not be directly transmitted to the position indicator 3, so that the position indicator 3 can be prevented from being damaged by overheating. At the same time, the gear transmission part is installed on the mounting base plate 2 that can be slid up and down. The transmission shaft 10 is a cantilever structure, and there will be eccentricity in rotation. During the eccentric rotation, the gear transmission part can move up and down with the mounting base plate 2, and then the gears of the gear transmission part will not cause tooth disengagement or squeezing, so the position indicator 3 can be prevented from malfunctioning.

[0025] In this embodiment, it should be noted that, please continue to refer to Figure 1-Figure 3 As shown, the bottom plate 1 is vertically arranged and fixed on the side of the oven, and a slide groove 11 is arranged on the side of the bottom plate 1 away from the side of the oven, and the slide groove 11 is arranged vertically. The mounting base plate 2 is vertically arranged and located on the side of the bottom plate 1 away from the side of the oven, and a slide bar is fixed on the side of the mounting base plate 2 facing the bottom plate 1, and the slide bar is adapted to the slide groove 11, and then the mounting base plate 2 is slidably connected with the bottom plate 1 by sliding the slide bar in the slide groove 11.

[0026] In this embodiment, it should be noted that the gear transmission member includes a driving gear 41 and a driven gear 42, a mounting hole 23 is provided at the middle position of the mounting base plate 2, the driving gear 41 is installed in the mounting hole 23, and the transmission shaft 10 passes through the clearance hole 12 of the base plate 1 and is coaxially connected to the driving gear 41. Therefore, the transmission shaft 10 will drive the driving gear 41 to rotate during the eccentric rotation, and at the same time, due to the eccentricity, the mounting base plate 2 will slide up and down along the direction of the slide slot 11.

[0027] The driven gear 42 is arranged on the mounting base 2 and meshes with the driving gear 41 for transmission. The rotating shaft of the driven gear 42 is coaxially connected to the position indicator 3. Then, in this embodiment, the driving gear 41 and the driven gear 42 are simultaneously mounted on the mounting base 2 which can slide up and down. During the eccentric rotation of the transmission shaft 10, the driving gear 41 and the driven gear 42 can simultaneously follow the mounting base 2 to move up and down, thereby ensuring that the driving gear 41 and the driven gear 42 are always in a meshing state, and there will be no tooth disengagement or squeezing, thereby ensuring the normal operation of the position indicator 3.

[0028] In addition, the material of the driven gear 42 is set to be a heat-insulating material, preferably a plastic material. In this way, when the driving gear 41 is connected to the hot transmission shaft 10 extending from the oven, the heat is transferred to the driven gear 42. Since the driven gear 42 is made of plastic material, the heat is isolated from being transferred to the position indicator 3 directly connected to the driven gear 42, thereby preventing the position indicator 3 from malfunctioning due to overheating.

[0029] It should be noted that, in the above embodiments, the structure of the gear transmission part can be realized by other structures besides the structure described in the embodiments. This application does not list them one by one, as long as they are within the spirit and principles of the above embodiments of this application, they all belong to the protection scope of this application.

[0030] In this embodiment, it should also be noted that the driven gear 42 is mounted on the mounting base 2 via the driven gear seat 5 . The driven gear seat 5 can be detachably mounted on the mounting base 2 and can slide synchronously with the mounting base 2 .

[0031] In one example, two guide bars 21 are detachably mounted on the side of the mounting base 2 facing away from the base plate 1. The two guide bars 21 are vertically arranged and spaced apart in the horizontal direction. The guide bar 21 is L-shaped. The driven gear seat 5 is located between the two guide bars 21. The two sides of the driven gear seat 5 are respectively slidably clamped between the two guide bars 21, so that the driven gear seat 5 can be slid up and down between the two guide bars 21. The driven gear 42 is installed on the driven gear seat 5 and can slide up and down synchronously with the driven gear seat 5.

[0032] In this embodiment, the driven gear seat 5 is restricted between the relatively arranged guide strips 21 and is slidably connected to the mounting base 2, and the driven gear 42 installed on the driven gear seat 5 is meshed with the driving gear 41. In combination with the arrangement of the guide strips 21, the driven gear seat 5 and the driven gear 42 can be prevented from being offset, and the driven gear 42 and the driving gear 41 can be prevented from being disengaged.

[0033] The guide bar 21 is fixed to the mounting base plate 2 by bolts, and a waist-shaped hole 22 is provided vertically on the mounting base plate 2. The guide bar 21 can be adjusted in height along the length direction of the waist-shaped hole 22 as needed. After the position is determined, the guide bar 21 can be fixedly connected to the mounting base plate 2 by bolts penetrating the guide bar 21 and passing through the waist-shaped hole 22. By setting the guide bar 21 with adjustable position, the height of the driven gear seat 5 limited between the relatively arranged guide bars 21 can be flexibly adjusted as needed, so as to better ensure the stable meshing of the driven gear 42 and the driving gear 41.

[0034] In this embodiment, it should also be noted that a clearance adjustment member is also provided at the top of the driven gear seat 5 for adjusting the gear clearance between the driven gear 42 and the driving gear 41. The clearance between the driven gear 42 and the driving gear 41 can be adjusted by the clearance adjustment member as needed to further ensure stable meshing of the driving gear 41 and the driven gear 42.

[0035] Specifically, a pressure block 7 is further provided on the side of the mounting base plate 2, and the pressure block 7 is located between the two guide bars 21. The gap adjustment member includes an adjustment threaded rod 6, and the lower end of the adjustment threaded rod 6 passes through the pressure block 7 and is rotatably connected to the top of the driven gear seat 5, and the adjustment threaded rod 6 is threadedly connected to the pressure block 7. A handle 61 is provided at the top of the adjustment threaded rod 6. When it is necessary to adjust the gear gap between the driving gear 41 and the driven gear 42, the adjustment threaded rod 6 is twisted by the handle. The adjustment threaded rod 6 can push the driven gear seat 5 to slide between the two guide bars 21 during the process of thread pushing, and then adjust the gear gap between the driven gear 42 and the driving gear 41, and further ensure the stable meshing of the driving gear 41 and the driven gear 42.

[0036] It should be noted that, in the above embodiments, the structure of the gap adjustment member can be realized by other structures besides the structure described in the embodiments. This application does not list them one by one, and all of them are within the scope of protection of this application as long as they are within the spirit and principles of the above embodiments of this application.

[0037] In this embodiment, it should be noted that the driving gear 41 is mounted in the mounting hole 23 of the mounting base plate 2 through the bearing 8, and the transmission shaft 10 is passed through the bearing 8 and is coaxially connected to the driving gear 41. The arrangement of the bearing 8 ensures that when the transmission shaft 10 drives the driving gear 41 to rotate, the position of the mounting base plate 2 will not rotate with the transmission shaft 10.

[0038] The implementation principle of this embodiment is as follows: the transmission shaft 10 can drive the mounting base plate 2 to slide up and down on the bottom plate 1 during the eccentric rotation, and at the same time drive the driving gear 41 to rotate, and the driving gear 41 meshes with the driven gear 42 to rotate, and the driving gear 41 and the driven gear 42 are both installed on the mounting base plate 2 that can slide up and down. Then, during the eccentric rotation of the transmission shaft 10, the driving gear 41 and the driven gear 42 can always maintain a meshing state, and the situation of tooth disengagement and squeezing will not occur, thereby ensuring the normal operation of the position indicator 3. At the same time, the driven gear 42 is made of heat-insulating material, which can isolate the heat-carrying transmission shaft 10 passing through the oven from directly transferring heat to the driven gear 42, and then transferring heat to the position indicator 3, causing the position indicator 3 to be overheated and damaged.

[0039] It should be understood that the above specific embodiments of the present application are only used to illustrate or explain the principles of the present application, and do not constitute a limitation to the present application. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present application should be included in the protection scope of the present application. In addition, the claims attached to the present application are intended to cover all changes and modifications that fall within the scope and boundaries of the attached claims, or the equivalent forms of such scope and boundaries.
