Description

Technical Field

[0001] This invention relates to the field of tracked tablet press technology, specifically a tracked air-cooled tablet press. Background Technology

[0002] In the field of continuous sheet production of hot melt materials, tracked air-cooled tablet presses, as core equipment integrating calendering, cooling and shaping, and conveying and collecting, are widely used in industries such as powder coatings, hot melt resins, rubber modification, hot melt adhesives, and chemical granule sheet production. Currently, most traditional tracked air-cooled tablet presses on the market have simple structures and limited functions, and generally suffer from numerous technical shortcomings in actual production, making it difficult to meet the modern production demands of high precision, high efficiency, low loss, and continuous operation. Specific defects are as follows: 1. Poor cooling system design leads to poor molding quality. Traditional tablet presses often use a single-sided fixed fan for direct cooling, resulting in uneven airflow distribution, non-adjustable airflow speed, and no segmented cooling design. When the hot-melt sheets are freshly discharged, they are hot and soft, and direct exposure to strong airflow for rapid cooling can easily generate internal stress, leading to problems such as warping, deformation, brittleness, and edge curling. At the same time, fixed-point airflow can easily cause local overcooling or undercooling, and the cooling of the upper and lower surfaces of the sheet is not synchronized, further aggravating defects such as uneven thickness, rough surface, and poor flatness, which seriously affect subsequent crushing, packaging, and product performance.

[0003] 2. Material adhesion is a prominent problem. Low-melting-point materials in continuous production are prone to adhering to the surface of the pressure rollers and conveyor belts during calendering and conveying. Traditional equipment lacks automated anti-adhesion measures and usually relies on manual periodic application of silicone oil or release agent. This not only results in uneven spraying and waste of agents, but also requires frequent machine shutdowns for cleaning, which is labor-intensive, poses high safety risks, and is prone to causing sheet tearing, material breakage, and stacking, significantly reducing production efficiency and equipment utilization.

[0004] 3. The edge material cannot be automatically recycled, resulting in serious raw material loss. During the tableting process, after the material is extended by the pressure roller, excess burrs will be generated on both sides. Traditional equipment does not have an edge material recycling mechanism. The cut edge material falls directly and accumulates. After cooling, it quickly hardens and clumps together. This not only makes it difficult to reuse, causing a lot of raw material waste, but also easily gets stuck in the transmission gap, leading to problems such as track deviation, roller surface wear, and increased motor load, thus increasing the equipment failure rate and maintenance costs.

[0005] 4. Low functional integration and low level of automation: Traditional tablet presses only have basic calendering and air-cooling functions, lacking integrated designs such as online shaping, automatic edge trimming, waste material return, and intelligent spraying. The processes are scattered, the workflow is lengthy, and there are many manual intervention steps.

[0006] Therefore, we first designed a tracked air-cooled tablet press that could improve tablet compression quality to solve these defects. Summary of the Invention

[0018] This invention provides a tracked air-cooled tablet press. Compared with existing technologies, it has the following advantages: (1) The tracked air-cooled tablet press combines the conveying return mechanism and the blowing tablet pressing mechanism. The two mechanisms can use the first conveying platform and the second conveying platform to transfer the material in a transitional manner. During the transfer, the blowing tablet pressing mechanism is used to cool the material in stages to avoid the material being cooled down rapidly under a wind speed, which would cause excessive internal stress and breakage. The first and second pressure rollers, together with the straightening guide and the blade, can cut and plasticize the material, thereby pressing the plate evenly. Excess material can be discharged into the return trough for secondary processing, avoiding the accumulation and solidification of residual material and causing waste.

[0019] (2) The tracked air-cooled tablet press significantly improves production stability and sheet forming quality through mechanical linkage automatic anti-stick spraying and segmented gradient air-cooling structure. When the equipment is running, the L-shaped plate and the arc-shaped pressure seat move back and forth synchronously with the threaded seat, intermittently triggering the pressing pump, and uniformly spraying silicone oil onto the sealed conveyor belt through the atomizing spray pipe to form an ultra-thin isolation layer, which prevents hot melt materials from sticking to the roller surface and conveyor belt from the source. It can run continuously for a long time without manual intervention. At the same time, the top T-shaped top frame, together with the air distribution plate, achieves gentle pre-cooling, and the bottom internal threaded blower frame moves back and forth with the threaded rod to dynamically cool the sheet on both sides, forming a gradient cooling curve of pre-cooling, strong cooling, and shaping, effectively eliminating internal stress, preventing the sheet from warping, deforming and cracking, and greatly improving the flatness and appearance quality of the finished product.

[0020] (3) This tracked air-cooled tablet press achieves fully automated recycling and closed-loop utilization of side scrap materials, fundamentally reducing raw material loss and improving equipment maintainability. During the tablet pressing process, the straightening guide and the blade precisely cut the edges of the plate. The cut scrap materials automatically fall into the return trough through the discharge port. Under the linkage drive of the U-shaped frame, toothed groove and gear cylinder, the auger blades stably transport the waste material to the discharge pipe, and finally return it to the arc-shaped frame feeding area to fuse with the new molten material for reprocessing. The entire return system is completely mechanically synchronized with the main machine, requiring no additional power, avoiding the accumulation, solidification and blockage of scrap materials, significantly improving the raw material utilization rate, reducing production costs, simplifying the equipment structure, and improving operational reliability and service life.

The blower tableting mechanism 2 includes a trapezoidal frame 201, which is installed on the upper part of the first feeding table 102. A fourth rotating rod 202 is rotatably installed between the front and rear parts of the inner cavity of the trapezoidal frame 201 through an opening. Several fourth rotating rods 202 are provided. A first pressure roller 206 and a second pressure roller 207 are respectively installed on the surface of several fourth rotating rods 202. The second pressure roller 207 is located between two straightening guides 109. Several fourth rotating rods 202 are connected by a fifth pulley 208 and a fifth belt 209. The surface of the trapezoidal frame 201 and the surface of the first rotating rod 104 on the left are both provided with a fourth pulley 203. The first rotating rod 104 is fixedly connected to the fourth pulley 203. The trapezoidal frame 201 is rotatably connected to the fourth pulley 203 through a bearing. The two fourth pulleys 203 are connected by a fourth belt 204. The surface of the fourth pulley 203 and the surface of the fourth rotating rod 202 on the left are both fixedly connected with meshing gear rings 205. A T-shaped top frame 210 is fixedly installed on the top of the trapezoidal frame 201 through an opening. A blower 211 is installed on the top of the equipment box 101. A venting pipe 215 is installed on the right side of the blower 211. One end of the venting pipe 215 passes through the equipment box 101 and the T-shaped top frame 210 and extends to the inside of the T-shaped top frame 210. An air expansion frame 212 is fixedly installed at the end of the venting pipe 215 that extends into the inside of the T-shaped top frame 210. An air distribution plate 214 is fixedly installed at the bottom of the T-shaped top frame 210 through an opening. An air outlet pipe 213 is fixedly installed at the bottom of the venting pipe 215 and inside the T-shaped top frame 210 through an opening. The rear end of the air guide pipe 149 passes through the equipment box 101 and is connected to the air outlet of the blower 211.

[0026] In operation, the motor 108 is started first. The transmission of the first pulley 140, first belt 141, third pulley 146, third belt 147, second pulley 144, second belt 145, fourth pulley 203, fourth belt 204, fifth pulley 208, and fifth belt 209 drives the sealed conveyor belt 106 and the mesh conveyor belt 138 synchronously. Meanwhile, the first pressure roller 206 and the second pressure roller 207 rotate in opposite directions through the meshing of two gear rings 205. At this time, the melting device 112 feeds the molten material through the injection pipe 111 in an intermittent manner. Since the injection pipe 111 is located directly above the arc frame 117, the material falls on top of the sealed conveyor belt 106 and inside the arc frame 117. Then, the transmission of the sealed conveyor belt 106 drives the material to move to the left. At this time, the first pressure roller 206 performs initial rolling on the material through its width, thereby flattening the material as a whole. The excess material on both sides is squeezed and extends forward and backward on the top of the sealed conveyor belt 106. As the sealed conveyor belt 106 moves to the left, the blade 110 cuts the material, and then forms a flat rectangular plate between the two straightening guides 109. The excess waste cut off by the blade 110 is guided by the straightening guides 109 and squeezed into the material outlets 116 on both sides and falls into the inner side of the return trough 113. Then, the blower 211 starts and uses the air duct 215 to ventilate. First, the air blown out of the air outlet duct 213 is dispersed by the air distribution plate 214, making it uniform and The air is gently blown onto the material for initial cooling. After the material is cut into rectangular plates by the blade 110, it is conveyed to the bottom of the air-expanding frame 212 by the sealed conveyor belt 106. The air blown out by the air-expanding frame 212 then directly contacts the plate to cool and shape it. The cut plate is then double-pressed by the second pressure roller 207 and limited by the straightening guide 109 to make the plate evenly pressed. The plate is then conveyed by the sealed conveyor belt 106 and transferred to the top of the mesh conveyor belt 138. As the mesh conveyor belt 138 moves the plate, the internal threaded blower frame 148 moves back and forth under the action of the first threaded rod 142. The movement of the plate causes the internal threaded blower frame 148 to blow air onto the bottom of the plate in a curved shape. The blowing action separates the sheet material from the mesh conveyor belt 138 and provides secondary heat dissipation to the bottom of the sheet material. Simultaneously, the first threaded rod 142 rotates, and the second pulley 144 drives the second threaded rod 143 to rotate as well. The rotation of the second threaded rod 143 is limited by the longitudinal guide plate 150, causing the threaded seat 151 and the longitudinal guide plate 150 to reciprocate. Each reciprocating movement causes the arc-shaped pressure seat 154 to press the pressure head 133, thereby spraying silicone oil onto the surface of the sealing conveyor belt 106 through the atomizing nozzle 134. This reduces the adhesion between the material and the sealing conveyor belt 106. Furthermore, because the inclined slide 153 is slidably connected to the pressure column 130, when the pressure column 130 moves forward, it pushes the two U-shaped frames 122 to rise synchronously.When the U-shaped frame 122 is at its bottom, the two magnetic guide blocks 124 are separated from the guide plate 121. Simultaneously, the front magnetic guide block 124 is attracted by the second magnetic block 126, causing the U-shaped frame 122 to move forward under the sliding action of the rectangular sliding opening 127. This causes the toothed groove 123 on the rear inner side of the U-shaped frame 122 to mesh with the gear cylinder 119. As the U-shaped frame 122 rises, the right magnetic guide block 124 enters the right guide plate 121 for guidance and fixation. The toothed groove 123 drives the gear cylinder 119 to rotate clockwise. When the U-shaped frame 122 rises to its top, the toothed groove 123 separates from the gear cylinder 119, and the same magnetic guide block 124 separates from the guide plate 121 again. However, at this time... The rear magnetic guide block 124 is attracted by the first magnetic block 125, thereby driving the U-shaped frame 122 to move backward. When the inclined slide 153 presses down on the bearing column 130 and the U-shaped frame 122 descends, the rear magnetic guide block 124 enters the guide slide 121, and the front toothed groove 123 meshes with the gear cylinder 119, driving the gear cylinder 119 to continue rotating clockwise. The continuous clockwise rotation of the gear cylinder 119 also drives the second rotating rod 114 and the auger blade 115 to rotate, so that the auger blade 115 conveys the excess material inside the return trough 113, and then squeezes it out from the discharge pipe 118 to the inside of the arc frame 117, where it merges with the material dripping from the injection pipe 111 and continues to be rolled.
