Technical Field
[0001] This utility model relates to the technical field of water-cooled double-roller tablet presses, and in particular to a water-cooled double-roller tablet press. Background Technology
[0002] A water-cooled twin-roll tablet press is a mechanical device used for forming or pressing materials into tablets. It mainly consists of two opposing rotating metal rollers, with cooling water circulating inside to control the operating temperature. Its working principle is to extrude, compact, or calender materials (such as metal powder, plastics, rubber, or chemical raw materials) using the twin rollers to form sheets, strips, or other specific shapes. The cooling system prevents the rollers from overheating, ensuring continuous and stable production while avoiding changes in material properties due to high temperatures. This equipment is widely used in metallurgy, chemical industry, pharmaceuticals, battery materials, and other fields, featuring high efficiency, strong controllability, and adaptability to various materials.
[0003] In the prior art, Chinese utility model patent CN206501468U discloses a double-roller water-cooled tablet press, including a fixed frame and a drive device. A conveying mechanism is fixedly installed on the fixed frame, and a cooling water tank is installed on the upper right side of the fixed frame. A hopper is fixed on the left side of the fixed frame, and a uniform discharge device is connected below the hopper. The front end of the main pressure roller is connected to a conveying roller via a transmission structure. The front end of the hollow shaft is connected to the cooling water tank via a water supply pipe, and a control valve is installed in the middle of the water supply pipe. A small gear is installed behind the main pressure roller, and a large gear is installed behind the side passive pressure roller. A driven wheel is fixed to the outer side of the rear of the large gear. The drive device is connected to the driven wheel. This double-roller water-cooled tablet press has a reasonable structural design. The equipment uses pneumatic valves and pressurized water pumps to control the water cooling system, making the equipment cool more evenly and stabilizing the water delivery, enabling better material tableting operations and promoting the development of the tablet press industry.
[0004] Problems compared with existing technologies: Some existing water-cooled twin-roll tablet presses cannot adjust the tablet thickness at any time during use, making it difficult for them to meet the tableting needs of various thicknesses, and their functionality needs to be improved.
[0005] Therefore, there is an urgent need for a water-cooled double-roller tablet press. Utility Model Content
[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a water-cooled double-roller tablet press.
[0007] The present invention solves its technical problem through the following technical solution: It includes a frame and an adjustment mechanism disposed on one side of the frame for adjusting the tablet thickness of the water-cooled double-roller tablet press. It also includes a cooling mechanism disposed on one side of the adjustment mechanism for cooling the double-roller tablet press. The adjustment mechanism includes a bidirectional electric push rod, which is bolted to the outer wall of the frame. Mounting blocks are fixed at both ends of the bidirectional electric push rod, and a heat-conducting pipe is disposed in the middle of the mounting blocks.

Similarly, the tablet thickness can be decreased. Synchronous gears ensure that the two rollers of the water-cooled double-roll tablet press rotate synchronously in opposite directions, allowing the tablet thickness to be adjusted at any time during use. This enables the water-cooled double-roll tablet press to meet various tablet thickness requirements, enriching its functionality.
[0016] 2. By cooperating with the toothed belt pulley, multiple transmission rollers are ensured to rotate synchronously, thereby driving the conveyor belt to rotate, ensuring the smooth feeding of the water-cooled double-roll tablet press. The position of the baffle is adjusted by the paddle, thereby adjusting the feeding speed of the water-cooled double-roll tablet press, ensuring that the water-cooled double-roll tablet press can meet the tableting operations at various speeds.
[0017] 3. By increasing the heat dissipation area of the reflux pipe through heat dissipation fins, and by using heat transfer oil and heat transfer plates to cool the water-cooled twin-roll tablet press, the heat dissipation efficiency of the water-cooled twin-roll tablet press is ensured.

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0033] Example 1
[0034] like Figure 1-6As shown, a water-cooled double-roll tablet press includes a frame 100 and an adjustment mechanism disposed on one side of the frame 100 for adjusting the tablet thickness. It also includes a cooling mechanism disposed on one side of the adjustment mechanism for cooling the double-roll tablet press. The adjustment mechanism includes a bidirectional electric actuator 101, which is bolted to the outer wall of the frame 100. Mounting blocks 102 are bolted to both ends of the bidirectional electric actuator 101. When the bidirectional electric actuator 101 extends, it moves the mounting blocks 102 away from each other; when it shortens, it moves the mounting blocks 102 closer together. The frame 100 has cut edges on both sides. A slot 120 is cut into the mounting block 102, which is slidably connected to the slot 120. A heat-conducting pipe 103 is rotatably connected to the middle position of the mounting block 102. A lifting electric push rod 104 is bolted to the top of the frame 100. A lifting frame 105 is bolted to the extended end of the lifting electric push rod 104. The lifting electric push rod 104 drives the lifting frame 105 to rise and fall. Pulleys A106 are rotatably connected to both ends of the lifting frame 105. A pulley B107 is bolted to one end of the heat-conducting pipe 103. A belt 108 is drivingly connected to the outer side of pulleys A106 and B107. One side of pulley A106 is bolted to... A synchronous gear 109 is provided, and a motor is bolted to one side of the synchronous gear 109. The motor drives the synchronous gears 109 at both ends of the lifting frame 105 to rotate synchronously in opposite directions. The cooling mechanism includes a connecting pipe 201, which is rotatably connected to both ends of a heat-conducting pipe 103. Rotary joints 110 are bolted to both ends of the heat-conducting pipe 103. One end of the rotary joint 110 is rotatably connected to the connecting pipe 201. Coolant is filled inside the heat-conducting pipe 103. A circulation pump 202 is bolted to one end of the connecting pipe 201, and a return pipe 203 is bolted to one end of the circulation pump 202. 2. The coolant is circulated along the return pipe 203. The outside of the return pipe 203 is fixed with heat dissipation fins 204 by bolts. The heat dissipation fins 204 increase the heat dissipation area of the return pipe 203. Multiple heat conduction plates 205 are evenly installed on the outside of the heat conduction pipe 103. The outside of the heat conduction pipe 103 is fixed with extrusion rollers 206 by bolts. Heat conduction oil is added inside the extrusion rollers 206. The heat conduction plates 205 conduct heat from the heat conduction oil. The outer wall of the frame 100 is welded with a track 200. The inner wall of the track 200 is slidably connected with a slider 300. The slider 300 slides along the track 200 to limit the movement trajectory of the connecting pipe 201.
[0035] In this embodiment, the bidirectional electric push rod 101 drives the mounting block 102 to move. When it is necessary to increase the tablet thickness, the bidirectional electric push rod 101 extends, causing the mounting blocks 102 to move away from each other. At the same time, the lifting electric push rod 104 drives the lifting frame 105 to move down, ensuring the clamping force of the belt 108 on the pulleys A106 and B107, thereby increasing the tablet thickness of the water-cooled double-roller tablet press. Similarly, the tablet thickness of the water-cooled double-roller tablet press can be decreased. The synchronous gear 109 ensures that the two rollers of the water-cooled double-roller tablet press rotate synchronously in opposite directions, so that the tablet thickness can be adjusted at any time during use. This allows the water-cooled double-roller tablet press to meet the tableting operations of various thicknesses, enriching the functionality of the water-cooled double-roller tablet press. The heat dissipation fins 204 increase the heat dissipation area of the return pipe 203, and the heat transfer oil and heat transfer plate 205 cool the water-cooled double-roller tablet press, ensuring the heat dissipation efficiency of the water-cooled double-roller tablet press.

A toothed pulley 303 is bolted to one end of the transfer roller 302. A toothed belt 304 is connected to the outer side of the toothed pulley 303. The toothed pulley 303 and the toothed belt 304 cooperate to ensure multiple transfers... The conveyor roller 302 rotates synchronously, and a conveyor belt 305 is rotatably connected to the outer side of the conveyor roller 302. A feeding mechanism is provided above the frame 100 for feeding the material to be pressed into tablets. The feeding mechanism includes a storage box 401, which is fixed to the upper part of the frame 100 by bolts. A feeding pipe 402 is welded to the lower part of the storage box 401.

[0038] In this embodiment, the toothed pulley 303 and the toothed belt 304 cooperate to ensure that multiple transmission rollers 302 rotate synchronously, thereby driving the conveyor belt 305 to rotate, ensuring the smooth feeding of the water-cooled double roller tablet press. The position of the baffle 403 is adjusted by the paddle 404, thereby adjusting the feeding speed of the water-cooled double roller tablet press, ensuring that the water-cooled double roller tablet press can meet the tableting operations at various speeds.
