Description

Technical Field

[0001] The utility model relates to the technical field of diaphragm stretching, in particular to a track structure. Background Art

[0002] In the wet process of diaphragm production, a transverse stretching mechanism or a biaxial stretching mechanism is required to stretch the film, that is, the edge of the film is clamped by a chain clamp at the entrance of the equipment, and then the chain clamp moves on a specific track. The film is preheated, stretched, shaped, cooled and other processes in turn, and finally a diaphragm with uniform film thickness and meeting the requirements is formed. The length of the transverse stretching mechanism or biaxial stretching mechanism of the diaphragm is usually 20m-40m, so the chain clamp walking track is usually composed of several tracks spliced ​​together.

[0003] Existing chain clamp walking tracks usually have plug-in structures at the joints to compensate for installation errors in the length direction and adapt to the adjustment of the track width. However, there are uneven upper end faces and side faces at the track joints. When the chain clamp passes through the joints, it will collide with the uneven joints, causing wear on the rollers of the chain clamp, which has an adverse effect on the life of the chain clamp bearings and the track. At present, the conventional practice is for workers to manually polish the joints with oilstones after the track is installed, but manual polishing is time-consuming and labor-intensive, and a large amount of metal powder will be generated during the polishing process. If the metal powder is not cleaned up, it will affect the quality of the diaphragm.

[0004] In view of this, the purpose of the utility model is to provide a new technical solution to solve the existing technical problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-5 The utility model is further described.

[0022] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0023] Reference Figures 1 to 5 A track structure includes a track body 1, and a plurality of track bodies 1 are connected in sequence to form a track structure for a chain clamp 4 to travel. A first plug-in portion 2 and a second plug-in portion 3 are respectively provided at both ends of the track body 1, and the first plug-in portion 2 is plugged into the second plug-in portion 3 to realize the connection between adjacent track bodies 1. The first plug-in portion 2 includes a plug-in plate 21, and a plug-in slot 31 is provided on the second plug-in portion 3. The plug-in slot 31 extends from the end of the second plug-in portion 3 along the length direction of the track body 1, and the plug-in plate 21 can be plugged into the plug-in slot 31. When installing and connecting each track body 1, the length of the first plug-in portion 2 plugged into the second plug-in portion 3 can be adjusted according to actual installation needs to adjust and compensate for the installation error of the track structure in the length direction. The track body 1, the first plug-in portion 2 and the second plug-in portion 3 are integrally formed. This track structure is suitable for steel belt track structures and full-plate track structures. It has a simple structure and is easy to install, which effectively improves the installation efficiency.

[0024] The first plug-in portion 2 is also fixedly provided with a first limiting strip 22, which is arranged on opposite sides of the plug-in board 21, and the second plug-in portion 3 is provided with first limiting grooves 32 on opposite sides, and the first limiting strip 22 and the first limiting grooves 32 are arranged one by one. In this embodiment, two first limiting strips 22 are arranged on each side of the plug-in board 21, and the first limiting strip 22 is formed integrally with the track body 1. Correspondingly, two first limiting grooves 32 are arranged on each side of the second plug-in portion 3, and the first limiting grooves 32 are connected to the plug-in groove 31. When the plug-in board 21 is plugged into the plug-in groove 31, the first limiting groove 32 is plugged into the first limiting groove 32, and the second plug-in portion 3 is located between the two first limiting strips 22 on the same side. The first limiting strip 22 and the first limiting groove 32 are used in conjunction with each other to limit the two adjacent track bodies 1 plugged together, thereby reducing the possibility of the adjacent track bodies 1 being separated during use.

[0025] Reference Figure 3 and Figure 4 The first limit strip 22 is provided with a first transition slope 221. Specifically, the first limit strip 22 located on the side close to the upper end face of the track structure is provided with a first transition slope 221. The first transition slope 221 is located on the end face of the limit strip close to the edge of the track structure, and the first transition slope 221 is inclined downward along the advancing direction of the chain clip 4. The second plug-in portion 3 is provided with a second transition slope 33. The second transition slope 33 is inclined toward the first limit groove 32, and the second transition slope 33 and the first transition slope 221 are located on the same side of the track structure. The first limit slope and the second transition slope 33 are provided to compensate for the unevenness of the upper end faces of the joints of the adjacent track bodies 1 caused by processing and installation errors. When the chain clip 4 structure passes through the joint, due to the transition buffering effect of the first transition slope 221 and the second transition slope 33, the chain clip 4 bearing 41 can pass smoothly without collision and wear with the joint, effectively ensuring the service life of the track and the chain clip 4 bearing 41.

[0026] Reference Figure 3 and Figure 4 , the end of the first plug-in part 2 is fixedly connected with a second limiting strip 23, the second plug-in part 3 is provided with a second limiting groove 34, the second plug-in strip corresponds to the second limiting groove 34 one by one, and the second limiting groove 34 is connected to the plug-in groove 31, when the plug-in board 21 is plugged into the plug-in groove 31, the second plug-in strip is plugged into the second limiting groove 34. In this embodiment, two second limiting strips 23 are fixedly connected to the end of the first plug-in part 2, and the second limiting strips 23 are integrally formed with the first plug-in part 2. Correspondingly, the second plug-in part 3 is also provided with two second limiting grooves 34. The second limiting groove 34 is used in conjunction with the second limiting strip 23 to further limit the mutually plugged track bodies 1, and further ensure the connection stability between adjacent track bodies 1.

[0027] The second plug-in part 3 is provided with a first transition slope 36, which is inclined from the second plug-in part 3 to the first limit groove 32. The first transition slope 36 is provided to play a transition buffering role at the connection between the first limit strip 22 and the second limit part. When the chain clip 4 moves from the first limit strip 22 of the previous track body 1 to the second plug-in part 3 of the adjacent track body 1, it can smoothly climb up the second plug-in part 3 from the first transition slope 36, effectively avoiding the possibility of collision between the bearing 41 of the chain clip 4 and the side end face of the second plug-in part 3. The track body 1 is provided with a second transition slope 11 on one side close to the first plug-in part 2, and the second transition slope 11 is inclined from the aisle body to the plug-in board 21. The end of the second plug-in part 3 is provided with a third transition slope 37, and the second transition slope 11 and the third transition slope 37 are provided correspondingly. The second transition slope 11 and the third transition slope 37 play a transition buffer role on the joint of the inner and outer sides of the track structure, which can compensate for the unevenness of the relative sides of the joint caused by processing and installation errors, so that the chain clip 4 bearing 41 running on the inner and outer sides of the track structure can run smoothly when passing through the joint.

[0028] The second plug-in portion 3 is provided with a third transition slope 35, which inclines from the second plug-in portion 3 to the second limiting groove 34, and the third transition slope 35 is located on the side of the second plug-in portion 3 close to the upper end surface of the track structure. The third transition slope 35 performs transition buffering on the connection between the second limiting strip 23 of the previous track body 1 and its adjacent second plug-in portion 3. When the chain clamp 4 structure passes through the joint, due to the transition buffering effect of the third transition slope 35, the bearing 41 of the chain clamp 4 on the upper end surface of the track can pass smoothly without colliding and wearing with the joint, thereby further ensuring the service life of the track and the bearing 41 of the chain clamp 4.

[0029] It should be noted that the first transition slope 36, the second transition slope 11, the third transition slope 37, the first transition slope 221, the second transition slope 33 and the third transition slope 35 are all opened corresponding to the walking track of the bearing 41 of the chain clamp 4. When actually opened, they can be set accordingly according to the working position of the bearing 41 of the chain clamp 4 and the track structure.

[0030] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
