Description

Technical Field

[0001] This utility model relates to the technical field of PET sheet production equipment, and in particular to a split roller extension sleeve. Background Technology

[0002] In the biaxial stretch molding process of PET sheets, the sheets need to be wound around multiple sets of rollers on the membrane bridge and conveyed in an arched shape. Due to different customer orders and equipment alignment errors in large production lines, when producing wide sheets, some sheets tend to extend beyond the edge of the membrane bridge rollers. When the sheets extend beyond the rollers to a certain extent, the edges will fold, causing the trimmed edge sheets to fail to accurately enter the feed inlet of the suction duct. In severe cases, they may even run out of the feed inlet, causing sheet breakage or even machine shutdown, significantly reducing the stability of equipment operation and affecting production efficiency.

The first semicircular sleeve 1 has a first mounting hole 11, in which a first screw 12 is installed. The second semicircular sleeve 2 has a second threaded hole 23 corresponding to the position of the first mounting hole 11, and the first screw 12 is threaded into the second threaded hole 23. The second semicircular sleeve 2 has a second mounting hole 21, in which a second screw 22 is installed. The first semicircular sleeve 1 has a first threaded hole 13 corresponding to the position of the second mounting hole 21, and the second screw 22 is threaded into the first threaded hole 13. The first semicircular sleeve 1 and the second semicircular sleeve 2... Each of the two semicircular sleeves 2 is fixedly connected to a clamping plate 3. The clamping plate 3 has a clamping groove 31. A first mounting hole 11 and a second threaded hole 23 are used to install a first screw 12. The second mounting hole 21 and the first threaded hole 13 are used to install a second screw 22. The first semicircular sleeve 1, the second semicircular sleeve 2, and the clamping plate 3 constitute the main structure of the extension sleeve. The clamping plate 3 is held on the shoulder of the roller through the clamping groove 31. Both the first semicircular sleeve 1 and the second semicircular sleeve 2 have a third threaded hole 33, which extends through the clamping groove 31. A third screw 34 is threaded into the third threaded hole 33. The third threaded hole 33 is used to install the third screw 34, which improves the stability of the extension sleeve assembly. An elastic pad assembly 4 is installed in the groove 31. The elastic pad assembly 4 includes a third semi-circular sleeve 41, a second through hole 42, a flange 43, a rib 44, a first connecting piece 45, a second connecting piece 46, and a third through hole 47. The third semi-circular sleeve 41 is fitted into the groove 31. The first connecting pieces 45 are fixedly connected to both outer walls of the third semi-circular sleeve 41 and are disposed on the clamping plate 3. A second connecting piece 46 is fixedly connected to one end of the first connecting piece 45. The second connecting piece 46 has a third through hole 47. The third semi-circular sleeve 41 is used to fit on the shaft shoulder. The first connecting piece 45 serves as a buffer structure between the two clamping plates 3, and the second connecting piece 46 serves as the first semi-circular sleeve 1 and the second semi-circular sleeve 2. The buffer structure between the two is used to avoid the first screw 12 and the second screw 22. Both ends of the third semi-circular sleeve 41 are fixedly connected with flanges 43, and ribs 44 are fixedly connected on the flanges 43. The outer walls on both sides of the clamping plate 3 are provided with slots 32, and the ribs 44 are set in the slots 32. The flanges 43 are used to support the ribs 44.

The first through holes 35 are used to realize the hollow design of the clamping plate 3 to reduce its weight. The third semi-circular sleeve 41 is provided with a second through hole 42 at the position corresponding to the third threaded hole 33. The second through hole 42 is used to avoid the third screw 34.

[0019] Working principle: When using this utility model, the roller surface is extended by installing it on the shoulder of the roller. Specifically, two elastic pad assemblies 4 are installed on two clamping plates 3 respectively, so that the third semicircular sleeve 41 is fitted into the clamping groove 31, and the protruding rib 44 on the flange 43 is engaged in the slot 32, thereby locking the position between the elastic pad assembly 4 and the clamping plate 3. Then, the first semicircular sleeve 1 and the second semicircular sleeve 2 are installed on the shoulder of the roller. The first screw 12 is inserted into the first mounting hole 11, passes through the third through hole 47 and is then inserted into the second threaded hole 23. The second screw 22 is inserted into the second mounting hole 21, passes through the third through hole 47 and is then inserted into the first threaded hole 13, thereby locking the first semicircular sleeve 1 and the second semicircular sleeve 2, and making the third semicircular sleeve 41 fit tightly. Finally, the third screw 34 is inserted into the third threaded hole 33 on the shoulder of the roller. The stability of the extension sleeve assembly can be further improved by adjusting the third screw 34 to make it press tightly against the shoulder of the roller. The first through hole 35 is used to realize the hollow design of the clamping plate 3 to reduce its weight. The second through hole 42 is used to avoid the third screw 34. The third screw 34 is located in the diameter direction of the extension sleeve. The first connecting piece 45 serves as a buffer structure between the two clamping plates 3. The second connecting piece 46 serves as a buffer structure between the first semicircular sleeve 1 and the second semicircular sleeve 2, which can solve the problem of dimensional deformation caused by temperature changes. The first semicircular sleeve 1 and the clamping plate 3 are an integral structure. The second semicircular sleeve 2 and the other clamping plate 3 are an integral structure. The elastic pad assembly 4 is an integral structure.
