Description

Technical Field

[0001] The utility model relates to the field of heat shrinkable tube processing, and specifically, to a surface grinding device. Background Art

[0002] A heat shrinkable tube is a special polyolefin-based heat shrinkable sleeve. Heat shrinkable tubes are divided into single-layer, double-layer and multi-layer heat shrinkable tubes, and different specifications and functions of heat shrinkable tubes are selected according to the usage scenarios. The double-layer heat shrinkable tube is processed by compounding a high-quality soft cross-linked polyolefin material on the outer layer and a hot melt adhesive on the inner layer. The outer layer material has characteristics such as insulation, corrosion prevention and wear resistance, and the inner layer has advantages such as low melting point, waterproof sealing and high adhesiveness.

[0003] Heat shrinkable tubes can be used in various application scenarios. According to the non-bacterial property of the heat shrinkable tube material itself, heat shrinkable tubes with surface frosting processing in daily life are often used to cover the contact positions of handrails such as fishing rods, badminton rackets, and the handles of bicycles and motorcycles. After the production of heat shrinkable tubes, during the process of processing them into specific products, it is necessary to perform frosting treatment on the outer surface of the heat shrinkable tubes so that the surface of the finished product has anti-slip performance and better adapts to specific application requirements.

[0004] When performing grinding treatment on heat shrinkable tubes, the conventional treatment method is to first cut the heat shrinkable tubes into the sizes required by the products. After cutting to the required sizes, the heat shrinkable tubes are sleeved outside a metal mold adapted to the tube body size, and the mold is rotated for grinding. Grinding by rotating the tube body of the heat shrinkable tube requires manual cutting of the heat shrinkable tubes into different length sizes in advance, and the heat shrinkable tubes that have been made cannot be directly subjected to frosting treatment, which is not conducive to the continuous operation of the production line.

[0034] Referring to Figure 1 、 Figure 2 and Figure 3 , Figure 1 is a three - dimensional view of the surface grinding device in the embodiment, Figure 2 is a three - dimensional view of the surface grinding device in the embodiment with part of the housing removed.Figure 3 A perspective view of the grinding assembly and the adjustment assembly of the surface grinding device in the embodiment. This embodiment provides a surface grinding device for grinding the outer surface of the pipe body 01.

[0035] A surface grinding device in this embodiment includes a grinding mechanism 1, a chip removal mechanism 2, and a limiting mechanism 3. The grinding mechanism 1 and the limiting mechanism 3 are arranged on the top surface of the chip removal mechanism 2. The grinding mechanism 1 is used for grinding the outer surface of the pipe body 01, and the chip removal mechanism 2 is used for collecting the waste chips generated during the grinding of the pipe body 01. The limiting mechanism 3 is used for fixing the pipe body 01, making the pipe body 01 more stable during continuous transportation, and reducing the shaking and instability generated during the grinding process.

[0036] The grinding mechanism 1 includes a housing 11, a rotating assembly 12, a grinding assembly 13, and an adjustment assembly 14. The rotating assembly 12 is connected to the housing 11, and the rotation of the rotating assembly 12 drives the adjustment assembly 14 and the grinding assembly 13 to rotate around the pipe body 01 together. The grinding assembly 13 is arranged inside the housing 11 and is used for grinding the pipe body 01. The adjustment assembly 14 is arranged inside the housing 11 and is connected to the rotating assembly 12. The grinding assembly 13 is fixed to the adjustment assembly 14 and is used for adjusting the distance between the grinding assembly 13 and the outer surface of the pipe body 01.

[0037] Before grinding, the cross-section of the pipe body 01 of the heat shrinkable tube is flat. An expansion gas such as inert gas or compressed gas is filled into one end of the pipe body 01, so that the pipe body 01 is propped up into a cylindrical shape for easy grinding. At the same time, the pipe body 01 passes through the grinding mechanism 1 at a set speed uniformly.

[0038] Start the grinding device. The rotating assembly 12 operates, driving the adjustment assembly 14 to rotate around the pipe body 01, and then driving the grinding assembly 13 to rotate around the pipe body 01. Then operate the grinding device to make the grinding assembly 13 operate. At this time, the grinding assembly 13 has not yet contacted the pipe body 01. Immediately drive the adjustment assembly 14 to make the grinding assembly 13 fixed to the adjustment assembly 14 move radially along the pipe body 01, so that the grinding assembly 13 approaches and contacts the pipe body 01 to grind the pipe body 01. Thus, while the pipe body 01 passes through the grinding mechanism 1 uniformly, the grinding assembly 13 grinds the pipe body 01 while rotating 360 degrees around the pipe body 01, and the grinding track on the pipe body 01 is spiral, realizing that the grinding assembly 13 grinds the outer surface of the pipe body 01 without dead angles. The chips generated after the grinding assembly 13 grinds the pipe body 01 fall by gravity and fall into the chip removal mechanism 2 below.

[0039] With this setting, when grinding, the grinding component 13 is rotated by the rotating component 12, and at the same time, the grinding component 13 rotates itself to grind the pipe body 01, without the need to rotate the pipe body 01. Therefore, there is no need to cut the pipe body 01 first and then perform the grinding operation. Once the heat shrinkable tube is manufactured, it can be ground, and the production line can operate continuously, with high automation, simple operation, greatly improving labor efficiency, saving costs, and improving production efficiency.

[0040] Further, the adjusting component 14 includes a rotating base 141, a slide rail 142 and a slider 143. The slide rail 142 is fixed to the rotating base 141, and the slider 143 is slidably connected to the slide rail 142. The grinding component 13 is connected to the slider 143, and the rotating base 141 is connected to the rotating component 12. By driving the slider 143, the slider 143 slides on the slide rail 142, and the slider 143 drives the grinding component 13 to slide along the slide rail 142 on the rotating base 141, so that the grinding component 13 approaches and contacts the pipe body 01.

[0041] See again Figure 3 , the grinding component 13 includes a first abrasive belt roller 131, a second abrasive belt roller 132, an abrasive belt 133, a first motor 134 and a base 135. The first abrasive belt roller 131 and the second abrasive belt roller 132 are arranged on the base 135. The abrasive belt 133 connects the first abrasive belt roller 131 and the second abrasive belt roller 132. The first motor 134 is connected to the first abrasive belt roller 131, and the base 135 is connected to the slider 143. When the first motor 134 is powered on, it drives the first abrasive belt roller 131 to rotate, and then drives the second abrasive belt roller 132 to rotate through the abrasive belt 133. The surface of the abrasive belt 133 contacts the outer surface of the pipe body 01 and grinds the pipe body 01. In this embodiment, two sets of grinding components 13 are provided, and the two sets of grinding components 13 are symmetrically arranged outside the pipe body 01. With this setting, the grinding efficiency is improved and the grinding effect is better.

[0042] In addition, see Figure 4 , the rotating component 12 includes a driving part 121, a first pulley 122, a second pulley 123, a belt 124 and a conductive slip ring 125. The driving part 121 is connected to the housing 11. The driving part 121 is connected to the first pulley 122. The belt 124 connects the first pulley 122 and the second pulley 123. The second pulley 123 is connected to the conductive slip ring 125. The conductive slip ring 125 is connected to the rotating base 141. The driving part 121 drives the first pulley 122 to rotate. The rotation of the first pulley 122 drives the belt 124 to run. The running of the belt 124 drives the second pulley 123 to rotate. The rotation of the second pulley 123 drives the conductive slip ring 125 to rotate synchronously. The conductive slip ring 125 drives the rotating base 141 to rotate, and further drives the grinding component 13 to rotate, realizing the rotation of the grinding component 13 around the pipe body 01.

[0043] Further, the driving unit 121 includes a driving motor 1211 and a worm and worm gear reducer 1212. The rotating shaft of the driving motor 1211 is connected to the power input end of the worm and worm gear reducer 1212, and the power output end of the worm and worm gear reducer 1212 is connected to the first pulley 122.

[0044] Refer again to Figure 4 , the slip ring 125 includes a rotating shaft 1251, a stator 1252 and a bearing 1253. One end of the rotating shaft 1251 is fixed to the rotating base 141, and the other end is rotatably connected to the stator 1252. The bearing 1253 is sleeved on the rotating shaft 1251. The second pulley 123 is sleeved on the rotating shaft 1251, and the bearing 1253 is fixed to the housing 11.

[0045] Refer to Figure 3 and Figure 4 , the rotating base 141 is provided with a positioning port 1410. The rotating shaft 1251 is inserted into the positioning port 1410 and fixedly connected to the positioning port 1410. With this setting, a tight connection between the rotating base 141 and the rotating shaft 1251 is achieved.

[0046] Refer again to Figure 5 , Figure 5 is a three-dimensional view of the limiting mechanism of the surface grinding device in the embodiment. The limiting mechanism 3 includes a bracket 31, two first limiting members 32 and two second limiting members 33. The bracket 31 is fixed to the top surface of the chip removal mechanism 2. The length direction of each first limiting member 32 is horizontal, and the two first limiting members 32 are arranged in parallel along the vertical direction on the bracket 31. The length direction of each second limiting member 33 is vertical, and the two second limiting members 33 are arranged in parallel along the horizontal direction on the bracket 31.

[0047] The limiting mechanism 3 surrounds the outer surface of the pipe body 01 by arranging two first limiting members 32 and two second limiting members 33, so as to limit the circumferential wall of the pipe body 01, and prevent the pipe body 01 from being collided and extruded during the grinding process of the grinding assembly 13, thereby causing the pipe body 01 to generate displacement in the radial direction and affecting the grinding effect. In this embodiment, in order to better prevent the pipe body 01 from shifting, two sets of limiting mechanisms 3 are provided, and the two sets of limiting mechanisms 3 are located at both ends of the grinding mechanism 1, so that the pipe body 01 is more stable during continuous conveying, reducing the shaking and instability generated during the grinding process, and making the grinding effect more ideal.

[0048] Furthermore, each first limiting member 32 and each second limiting member 33 include a rotating cylinder 301 and a fixed shaft 302. The fixed shaft 302 is arranged on the bracket 31. The rotating cylinder 301 is sleeved on the fixed shaft 302 and is rotatably connected to the fixed shaft 302. With this arrangement, when the first limiting member 32 and the second limiting member 33 limit the pipe body 01, the rotating cylinder 301 contacts the outer surface of the pipe body 01, and the rotating cylinder 301 rotates along with the pipe body 01 during the continuous transportation process, reducing the resistance while limiting the pipe body 01.

[0049] Refer to Figure 1 and Figure 2 , the housing 11 includes an outer shell 111 and a partition plate 112. There is a cavity 113 inside the outer shell 111. The partition plate 112 divides the cavity 113 into a first cavity 1131 and a second cavity 1132. The grinding assembly 13 and the adjusting assembly 14 are arranged in the first cavity 1131, and the stator 1252 is arranged in the second cavity 1132. An installation hole 1120 is formed on the partition plate 112, and the bearing 1253 is snap-fitted with the installation hole 1120. The settings of the outer shell 111 and the partition plate 112 limit the debris generated when the grinding assembly 13 grinds the pipe body 01 in the first cavity 1131, preventing the flying debris from running out or splashing into other components and affecting the operation of the equipment.

[0050] Refer to Figure 6 , the conductive slip ring 125 further includes a rotation stopping piece 1254, and the rotation stopping piece 1254 is fixed to the stator 1252. The housing 11 further includes a limiting rod 114, and the limiting rod 114 is fixed to the partition plate 112. The rotation stopping piece 1254 is provided with a clamping groove 1255, and the limiting rod 114 is snap-fitted with the clamping groove 1255. Thus, the rotation stopping piece 1254 is clamped to the limiting rod 114 to further fix the stator 1252.

[0051] Refer to Figure 2 , the chip removal mechanism 2 includes a frame 21 and a collection port 22. The first cavity 1131 is communicated with the collection port 22. With this arrangement, the debris generated by the grinding assembly 13 when grinding the pipe body 01 directly enters the chip removal mechanism 2, preventing the debris from splashing and affecting the operation of the equipment.

[0052] In summary, first, the driving part 121 drives the first pulley 122 to rotate. The second pulley 123 rotates synchronously with the first pulley 122 under the traction of the belt 124. The rotation of the first pulley 122 drives the rotation of the rotating shaft 1251, and the rotating shaft 1251 drives the rotation of the rotating base 141. The grinding assembly 13 fixed on the rotating base 141 first rotates around the pipe body 01. Then, the first motor 134 is started. The first motor 134 drives the first abrasive belt roller 131 to rotate. The second abrasive belt roller 132 rotates synchronously with the first abrasive belt roller 131 under the traction of the abrasive belt 133, and the abrasive belt 133 starts to operate. Immediately afterwards, the slider 143 is adjusted to move the base 135 along the slide rail 142. The first abrasive belt roller 131 and the second abrasive belt roller 132 fixed on the base 135 move together along the slide rail 142, so that the operating abrasive belt 133 approaches and contacts the pipe body 01 to grind the pipe body 01.

[0053] Thus, through the operation of the rotating assembly 12, the adjusting assembly 14 is driven to rotate around the pipe body 01 of the heat shrinkable tube. The grinding assembly 13 is fixed to the adjusting assembly 14, and then drives the grinding assembly 13 to rotate around the pipe body 01. Then, the grinding assembly 13 is started to make the grinding assembly 13 operate. Then, the adjusting assembly 14 is operated to make the abrasive belt 133 approach and contact the pipe body 01 for grinding, so that the grinding assembly 13 does not need to rotate the pipe body 01 when grinding the heat shrinkable tube, and thus there is no need to first cut the pipe body 01 and then perform the grinding operation. Once the heat shrinkable tube is manufactured, it can be ground. The production line can operate continuously, with high automation, simple operation, greatly improving labor efficiency, saving costs, and improving production efficiency.
