Description

Technical Field

[0001] The utility model relates to the technical field of heat shrinkable tube production, in particular to a winding tension frame for improving the quality of heat shrinkable tubes. Background Technique

[0002] The production process of heat shrinkable tubes involves multiple steps, including manufacturing heat shrinkable tubes using hot melt extrusion equipment, followed by cooling the formed tubes with a cooling device. Subsequently, the heat shrinkable tubes enter the winding tension frame stage, where they are appropriately stretched and finally wound. This winding tension frame is a device that ensures heat shrinkable tubes meet the design standards. It is equipped with tension wheels with adjustable spacing, brackets supporting these tension wheels, and guide wheels installed on both sides. The heat shrinkable tubes themselves are made from heated and melted particles through an extrusion process and are stretched and shaped by the tension wheels at a certain temperature.

[0003] However, the temperature of the heat shrinkable tubes coming out of the cooling device is still relatively high. When the heat shrinkable tubes are guided by the guide wheels on this side and the tension applied by the tension wheels is too large and cannot be effectively buffered and released, it may cause excessive stretching of the outer ends of the contact parts of the heat shrinkable tubes, thereby thinning the tube walls. This will result in uneven wall thickness of the heat shrinkable tubes after stretching and the problem that the finally wound heat shrinkable tubes may not meet the quality standards.

[0005] To solve the above-mentioned problems, the utility model provides the following technical solution: a winding tension frame for improving the quality of heat shrinkable tubes, including a tensioning component for tensioning. The tensioning component is arranged on a support component. One end of the support component is provided with an output wheel, and the other end is provided with an input wheel.

However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0030] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation mode of the present utility model. The "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an independent or selectively exclusive embodiment from other embodiments.

[0031] Embodiment

[0032] Referring to Figures 1 to 6 , which is an embodiment of the present utility model. This embodiment provides a winding tension frame for improving the quality of heat shrinkable tubes, including a tensioning component 200 for tensioning. The tensioning component 200 is arranged on the support component 100. One end of the support component 100 is provided with an output wheel 203, and the other end is provided with an input wheel 204. Both the output wheel 203 and the input wheel 204 are matched with the tensioning component 200. The feature is that: the outer surface of the input wheel 204 has a buffer member 205. The buffer member 205 is internally provided with a number of equally spaced partitions 205-1. Adjacent partitions 205-1 form a sealed cavity 205b. The partition 205-1 has micropores 205a-1 to enable mutual communication between adjacent cavities 205b.

[0033] Specifically, the tensioning component 200 is arranged on the supporting component 100. The heat-shrinkable tube 400 is rolled and guided from the input wheel 204 of the supporting component 100 to the roller of the tensioning component 200, and then rolled out from the output wheel 203 at the output end of the supporting component 100. There is a buffer 205 on the outer surface of the input wheel 204, which rolls relative to the outer surface of the heat-shrinkable tube 400. During this process, the contact end of the buffer 205 and the heat-shrinkable tube 400 is gradually compressed. Here, the cavity 205b is squeezed and discharges air or other media to the surrounding cavity 205b through the micropores 205a-1 of the partition 205-1. In this way, the contact end of the heat-shrinkable tube at the input wheel can be buffered. During the buffering process, since the media is discharged through the micropores to relieve pressure, the squeezed part of the buffer 205 gradually sinks slowly at the same time. The reverse pulling force acting on the heat-shrinkable tube 400 is converted by the way of pressure relief and the deformation of the buffer 205. The buffering effect is more linear and gentle, providing better buffering protection for the heat-shrinkable tube 400;

[0034] Further, as Figure 3 shown, the contact end of the buffer 205 and the outer surface of the input wheel 204 is provided with a protrusion 205a. Correspondingly, the outer surface of the input wheel 204 has a limit groove 204a, which is engaged with the protrusion 205a. The input wheel 204 is composed of two mirror-symmetrical parts spliced together. A screw hole 204b is provided on the side surface of the input wheel 204. The input wheel 204 is spliced to facilitate the installation of the buffer 205. The protrusion on the buffer 205 and the limit groove 204a of the input wheel 204 are engaged with each other to achieve the effect of synchronous operation of the input wheel 204 and the buffer 205. The buffer 205 can be made of silica gel material, and the partition 205-1 has the same material as the buffer. In this way, the silica gel itself has a certain buffering effect. By setting the buffer 205 made of silica gel material, the protection of the heat-shrinkable tube will be better;

[0035] In order to better protect the input end of the heat-shrinkable tube by the input wheel 204 and make the tensioning frame better adapt to heat-shrinkable tubes of different specifications, as Figure 5 、 Figure 6As shown, the input wheel 204 is arranged at the other end of the support assembly 100 through the fine-tuning assembly 300. Both ends of the support assembly 100 are extension plates 106. The fine-tuning assembly 300 is composed of a sleeve rod 301, a slider 302, a concave strip 302a, a sliding rod 303, a screw rod 304, and a rotating cap 304a. The sleeve rod 301 is used to sleeve on the input wheel 204 so that the input wheel 204 can roll freely. One end of the sleeve rod 301 is arranged on the slider 302. The slider 302 is sleeved on the sliding rod 303, and the middle part of the slider 302 is threadedly connected to the screw rod 304. One end of the screw rod 304 is provided with a rotating cap 304a. The slider 302 moves in the movable cavity 106a of the extension plate 106. Both ends of the sliding rod 303 are arranged on the surface of the movable cavity 106a. The screw rod 304 is arranged on the surface of the movable cavity 106a through a bearing. The outer surface of the slider 302 is provided with a concave strip 302a, which corresponds to the scale grooves 106b equally spaced on the outer surface of the extension plate 106;

[0036] For the fine-tuning assembly 300, from the perspective of simplicity in implementation, the slider 302 is sleeved on the sliding rod 303, and the screw rod 304 and the slider 302 are threadedly connected to effectively move the slider 302. The front and rear positions of the input wheel 204 are adjusted by aligning the scale groove 106b and the concave strip 302a to adjust whether there is a good guide for the heat shrinkable tube and prevent the excessive tension of the heat shrinkable tube on the input wheel 204;

[0037] Common tensioners adopt such as Figure 1 、 Figure 2 As shown, the support assembly 100 further includes a cross beam 101, a fixed bracket 101a, a support beam 102, a base 103, a lead screw 104, and a movable bracket 105. The tensioning assembly 200 further includes a fixed tensioning wheel 201 and a movable tensioning wheel 202. Both ends of the top of the base 103 are provided with support beams 102. The bottom of the support beam 102 is provided with a cross beam 101. The cross beam 101 is provided with a fixed bracket 101a, which is connected to the fixed tensioning wheel 201. A lead screw 104 is rotatably arranged between the cross beam 101 and the base 103. A movable bracket 105 is sleeved on the lead screw 104. The movable bracket 105 is provided with a movable tensioning wheel 202. The heat shrinkable tube 400 is rolled and guided from the input wheel 204 to the upper fixed tensioning wheel 201, winds several turns between the fixed tensioning wheel 201 and the movable tensioning wheel 202, and then is rolled and exported from the output wheel 203. The movable tensioning wheel 202 on the movable bracket 105 can be lifted and lowered by driving the lead screw 104 to change the distance between the movable tensioning wheel 202 and the fixed tensioning wheel 201, so as to change the tension of the heat shrinkable tube 400 passing through this tensioner.
