Description

Technical Field

[0001] This utility model relates to the field of hot press roller technology, specifically to a replaceable outer layer structure for hot press rollers. Background Technology

[0002] A hot press roller is a device that heats and presses products into shape through rolling. Hot press rollers are generally classified into three types according to their heating method: steam-heated hot press rollers, oil-heated hot press rollers, and electric-heated hot press rollers. In fields such as plastics processing and composite material production, hot press rollers utilize high temperatures (up to 350℃) to soften materials, combined with precise pressure control (e.g., 0.5-2.5MPa), to allow the material to adhere to the curved surface of the mold or bond between layers, forming a stable shape. For example, in the production of automotive interior parts, curved hot press rollers can be heated in segments according to the curvature of the mold to ensure uniform material adhesion. In lithium battery manufacturing, hot press rollers soften the binder through heating, reducing the risk of active particle breakage, while simultaneously enhancing the bonding force between the electrode coating and the current collector, reducing battery internal resistance, and improving energy density and cycle life. In the lamination process, chrome plating or ceramic treatment on the surface of the hot press roller can improve wear resistance, ensure a smooth and flat material surface, and avoid burrs or impurities affecting the quality of the finished product. For example, the lamination process of packaging materials requires precise control of temperature error (±1℃).

[0003] Chinese Patent Publication No. CN212684887U discloses a corrugated paper hot press roller, including a roller core 1, the roller core 1 is connected to an insulation layer 2, the insulation layer 2 is connected to an electric heating layer 3, the electric heating layer 3 is provided with a plurality of cylindrical holes 4 coaxial with the roller core 1, electric heating tubes 5 are connected in the cylindrical holes 4, the electric heating layer 3 is connected to a heat equalization layer 6, the heat equalization layer 6 is connected to a heat conduction layer 10, and an electric slip ring 12 is connected to the end of the roller core 1, and the electric heating tubes 5 are electrically connected to the electric slip ring 12.

[0004] However, the inventor of the above-mentioned device believes that there are certain defects. After a period of use, the outer surface of the hot press roller of the above-mentioned device will be worn. When the wear is severe, the entire hot press roller needs to be replaced, which has a high production cost. Therefore, this utility model provides a replaceable outer layer structure for the hot press roller. Utility Model Content

[0005] The purpose of this invention is to provide a replaceable outer layer structure for hot press rollers to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a replaceable outer layer structure for a hot press roller, comprising a hot press roller core and an outer roller sleeve, wherein the outer roller sleeve is fitted onto the outer surface of the hot press roller core, both ends of the hot press roller core are fixedly connected to a connecting shaft, both ends of the hot press roller core are slidably connected to multiple sliding stops, the connecting shaft is provided with an adjustment mechanism for driving the multiple sliding stops to slide, the adjustment mechanism includes a turntable rotatably connected to the connecting shaft, the turntable having an extrusion groove, the top of the sliding stops being fixedly connected to a connecting slider, the connecting slider being disposed inside the extrusion groove, and the connecting shaft being provided with a limiting mechanism for limiting the rotation of the turntable.

[0007] Preferably, one end of the hot press roller core is fixedly connected to a fixed slide rail, and the sliding stop bar is slidably connected inside the fixed slide rail, so that the sliding stop bar can slide stably at one end of the hot press roller core under the action of the fixed slide rail.

[0008] Preferably, each group of sliding stops consists of four sliding stops, which are arranged in a circular array at one end of the hot-pressing roller core. The multiple sliding stops provide multi-directional obstruction to one end of the outer roller sleeve.

[0009] Preferably, the limiting mechanism includes a rotating sleeve fixed on the turntable, the rotating sleeve being sleeved on a connecting shaft, a swing rod being mounted on the connecting shaft, a slot being formed on the outer surface of the rotating sleeve, and a plug being fixedly connected to the swing rod. The plug is inserted into the inside of the slot. By inserting the plug into the inside of the slot, the rotation of the rotating sleeve is limited, thereby limiting the rotation of the turntable on the connecting shaft.

[0010] Preferably, a support frame is fixedly connected to the connecting shaft, and the swing rod is hinged inside the support frame by a pin. By pressing one end of the swing rod, the insert at the other end of the swing rod is pulled out from inside the slot.

[0011] Preferably, one end of the swing rod is fixedly connected to a spring, and the other end of the spring is fixedly connected to the connecting shaft. Under the action of the spring, one end of the plug is stably inserted into the slot.

[0012] Preferably, a fixing strip is fixedly connected to the outer surface of the hot press roller core, and an inner groove corresponding to the fixing strip is opened on the inner wall of the outer roller sleeve. The fixing strip and the inner groove restrict the relative rotation between the outer roller sleeve and the hot press roller core.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This application involves placing an outer roller sleeve on the outer surface of a hot-pressing roller core. By rotating a turntable, multiple extrusion grooves and connecting sliders cause multiple sliding stops to slide away from the connecting shaft. Two sets of sliding stops at both ends of the hot-pressing roller core block the outer roller sleeve, thus installing it on the hot-pressing roller core. When the outer roller sleeve needs to be replaced, the turntable is rotated in the opposite direction, causing the sliding stops to slide and release the obstruction of the outer roller sleeve, making it easy to slide the outer roller sleeve off the hot-pressing roller core for replacement. This reduces the number of spare parts for the hot-pressing roller core and further reduces production costs.

[0015] 2. This application restricts the rotation of the turntable on the outer surface of the connecting shaft by means of the rotating sleeve, slot, support frame, swing rod and insert block, thereby improving the stability of the installation. In addition, the inner sliding groove and fixing strip prevent relative rotation between the outer roller sleeve and the hot pressing roller core. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The hot press roller has a replaceable outer structure, including a hot press roller core 1 and an outer roller sleeve 2. The outer roller sleeve 2 is fitted on the outer surface of the hot press roller core 1. A fixing strip 11 is fixedly connected to the outer surface of the hot press roller core 1. The inner wall of the outer roller sleeve 2 is provided with an inner sliding groove 21 corresponding to the fixing strip 11. By inserting the outer roller sleeve 2 from one end of the hot press roller core 1 onto the outer surface of the hot press roller core 1, the fixing strip 11 is inserted into the inner sliding groove 21 to restrict the relative rotation between the outer roller sleeve 2 and the hot press roller core 1.

[0024] Please refer to it again. Figure 1 , Figure 2 , Figure 4 and Figure 5 Both ends of the hot press roller core 1 are fixedly connected to a connecting shaft 3. Under the action of the connecting shaft 3, the entire device is installed on the frame. Both ends of the hot press roller core 1 are slidably connected to multiple sliding stops 5. One end of the hot press roller core 1 is fixedly connected to a fixed slide rail 4. The sliding stops 5 are slidably connected inside the fixed slide rail 4. The side of the fixed slide rail 4 is provided with a groove. The sliding stops 5 are fixedly connected to a slide bar that slides inside the groove. The bottom of the sliding stops 5 is in contact with the end face of the hot press roller core 1. There are four sliding stops 5 in each group. The four sliding stops 5 are distributed in a circumferential array at one end of the hot press roller core 1. By driving the sliding stops 5 to slide outwards around the connecting shaft 3, one end of the sliding stops 5 blocks the outer roller sleeve 2, so that the outer roller sleeve 2 is installed inside the hot press roller core 1. The final sliding position of one end of the sliding stops 5 is set at three-quarters of the thickness of the outer roller sleeve 2 to prevent one end of the sliding stops 5 from sliding beyond the outer surface of the outer roller sleeve 2.

[0025] Please refer to it again. Figure 1 , Figure 2 , Figure 4 and Figure 5 The connecting shaft 3 is equipped with an adjustment mechanism that drives multiple sliding stops 5 to slide. The adjustment mechanism includes a turntable 6 rotatably connected to the connecting shaft 3. The turntable 6 has a pressing groove 61. A connecting slider 51 is fixedly connected to the top of the sliding stops 5. The connecting slider 51 is located inside the pressing groove 61. By driving the turntable 6 to rotate on the outer surface of the connecting shaft 3, the connecting slider 51 is pressed by the pressing groove 61 to drive the sliding stops 5 to extend to the fixed slide 4 for sliding. The connecting slider 51 is cylindrical.

[0026] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 5The connecting shaft 3 is provided with a limiting mechanism to restrict the rotation of the turntable 6. The limiting mechanism includes a rotating sleeve 7 fixed on the turntable 6, which is sleeved on the connecting shaft 3. A swing rod 9 is installed on the connecting shaft 3. A slot 71 is opened on the outer surface of the rotating sleeve 7. An insert 91 is fixedly connected to the swing rod 9 and is inserted into the slot 71. By driving the rotating sleeve 7 to rotate, the turntable 6 is driven to rotate on the outer surface of the connecting shaft 3. The rotation of the turntable 6 is restricted by inserting one end of the insert 91 into the slot 71.

[0027] Please refer to it again. Figure 1 , Figure 2 and Figure 3 A support frame 8 is fixedly connected to the connecting shaft 3. The swing rod 9 is hinged to the inside of the support frame 8 by a pin. One end of the swing rod 9 is fixedly connected to a spring, and the other end of the spring is fixedly connected to the connecting shaft 3. By pressing one end of the swing rod 9, the other end of the swing rod 9 is raised, causing the insert 91 to be pulled out from the inside of the slot 71, allowing the rotating sleeve 7 to rotate freely. Under the action of the spring, the insert 91 is stably inserted into the inside of the slot 71.

[0028] Working principle: When the outer roller sleeve 2 on the outer surface of the hot press roller core 1 needs to be replaced, the spring is compressed by pressing one end of the swing rod 9, causing the insert block 91 to be pulled out from the inside of the slot 71. The rotating sleeve 7 is driven to rotate, causing the turntable 6 to rotate on the outer surface of the connecting shaft 3. The connecting slider 51 is pushed by the squeezing groove 61, causing the sliding stop 5 to slide inside the fixed slide rail 4, so that one end of the sliding stop 5 releases the obstruction of the outer roller sleeve 2. The outer roller sleeve 2 is removed from the hot press roller core 1 and replaced with a new outer roller sleeve 2. The turntable 6 is rotated in the opposite direction, and the connecting slider 51 is squeezed by the squeezing groove 61 to push the sliding stop 5 to slide outward. The sliding stop 5 blocks one end of the outer roller sleeve 2 to install the outer roller sleeve 2 on the outer surface of the hot press roller core 1. The fixing strip 11 and the inner slide rail 21 restrict the relative rotation between the outer roller sleeve 2 and the hot press roller core 1. Finally, the insert block 91 is inserted into the inside of the slot 71 to restrict the rotation of the rotating sleeve 7 on the connecting shaft 3.
