The extrusion motor can melt and blend the raw material and extrude it into the molding die 2 for forming. A casting processing mechanism 4 is provided in the casting supports 3. The table mat formed by the molding die 2 is cooled by the casting processing mechanism 4 to fix its shape. A hot pressing mechanism 5 and a winding mechanism 6 are provided in the casting supports 3. The hot pressing mechanism 5 is used to support the film material laminated on the table mat, and at the same time, the film and the table mat are overlapped by hot pressing. A trimming mechanism 7 for cutting the size of the table mat is symmetrically arranged on the casting supports 3. The trimming mechanism 7 is located between the hot pressing mechanism 5 and the winding mechanism 6. A collecting mechanism 8 is provided at the bottom of the casting supports 3. The winding mechanism 6 is used to wind up the trimmed table mat, and the collecting mechanism 8 is used to collect the edge parts cut off by the trimming mechanism 7, and at the same time absorb the impurities generated during the cutting process.

[0034] Please see Figures 1-2 and Figure 4The casting processing mechanism 4 includes a casting cooling roller 41 rotatably connected between casting supports 3 via bearings. A support plate 42 is provided on the casting supports 3, and an output pump 43 is provided on the support plate 42. The output end of the output pump 43 is connected to an air nozzle 44 via a pipe. The air outlet of the air nozzle 44 is located on one side of the casting cooling roller 41, and the air outlet of the air nozzle 44 is close to the discharge port at the bottom of the forming mold 2. The formed platform pad will flow out from the bottom of the forming mold 2 and fall. During the falling process, the airflow generated by the output pump 43 will be sprayed out through the air nozzle 44. The pad is cooled by airflow and adheres tightly to the casting cooling roller 41. A first motor reducer 45 is fixed to one side of the casting support 3. The output end of the first motor reducer 45 is fixedly connected to the casting cooling roller 41. The first motor reducer 45 drives the casting cooling roller 41 to rotate. A peeling roller 46 is rotatably connected between the casting supports 3. The peeling roller 46 supports the cooled pad and is located on one side of the casting cooling roller 41. As the pad passes around the peeling roller 46, it peels off from the casting cooling roller 41. Two sets of auxiliary cooling rollers 47 are evenly rotatably connected. One end of one of the auxiliary cooling rollers 47 is fixedly connected to the output end of a second motor reducer 48, which is fixed on the casting support 3. A first gear is fixed on the second gear auxiliary cooling roller 47, and the first gear meshes with the second gear.

A protective shell is provided on the casting support 3, and both the first and second gears are located inside the protective shell. The second motor reducer 48 drives one of the auxiliary cooling rollers 47 to rotate. During the process, the meshing of two continuously meshing second gears drives another auxiliary cooling roller 47 to rotate synchronously in the opposite direction. The molded pad will flow out from the bottom of the molding mold 2 and fall. During the fall, the airflow generated by the output pump 43 will be sprayed out through the jet nozzle 44. The outflowing pad will adhere tightly to the casting cooling roller 41 for cooling under the action of the airflow.

The pad after bypassing the auxiliary cooling roller 47 is completed.

[0035] Please see Figures 1-2 and Figure 4 The hot pressing mechanism 5 includes a feeding roller 51 rotatably connected between the casting supports 3. The feeding roller 51 is used to support the film to be laminated on the casting pad. The casting supports 3 are respectively rotatably connected by bearings to a hot pressing roller 52 and a glue roller 53.

[0036] Please see Figures 1-2 and Figure 4The winding mechanism 6 includes a winding roller 61 rotatably connected between the casting brackets 3 via bearings. One end of the winding roller 61 is fixedly connected to a third motor reducer 62, which is fixed on the casting brackets 3. The operation of the third motor reducer 62 provides winding power to the winding roller 61, thereby winding the composite film onto the winding roller 61.

[0037] Please see Figures 1-3 The finishing mechanism 7 includes cylinder brackets 71 fixed on both sides of the casting bracket 3. A first cylinder 72 is fixedly connected to the cylinder bracket 71. A first bracket 73 is fixedly connected to the output end of the first cylinder 72.

The first cylinder 72 drives the first bracket 73 to move, which can adjust the cutting width. The second cylinder 74 drives the second bracket 75 to move down, so that the cutting disc 77 contacts the table pad. The cutting action is achieved by the cutting motor 76 driving the cutting disc 77 to rotate.

[0038] Please see Figure 1 and Figures 3-6The collection mechanism 8 includes side support rods 81 symmetrically fixedly installed on both sides of the bottom of the casting support 3. The side support rods 81 are fixed to the connecting shell 82. A conical support bucket 83 is provided on the top of the connecting shell 82. The support bucket 83 is used to guide the cut edge material into the connecting shell 82. A filter shell 87 is provided at the bottom of the connecting shell 82. A filter plate 86 is provided at the connection between the bottom of the connecting shell 82 and the filter shell 87. The microporous structure on the filter plate 86 allows the cut debris and impurities to pass through and enter the filter shell 87. A filter element for adsorbing particulate impurities is embedded in the filter shell 87. An air pump 84 is provided on one side of the filter shell 87. The air pump 84 is connected to the filter shell 87. The air pump 84 provides a negative pressure environment for the filter shell 87. A collection shell 88 for collecting edge material is provided between 7, and an isolation and cutting mechanism 85 is provided above the collection shell 88. The isolation and cutting mechanism 85 includes T-shaped plates 851 symmetrically fixed to the top of the collection shell 88. A first roller 852 is rotatably connected between the two T-shaped plates 851 via a bearing. A second roller 854 is rotatably connected to the support bucket 83 via a bearing. A connecting belt 853 is wound around the second roller 854 and the first roller 852. An isolation plate 858 for isolating the connecting shell 82 and the collection shell 88 is symmetrically provided on the connecting belt 853. A cutting blade 859 for cutting edge material is provided on the isolation plate 858. The cutting blade 859 periodically cuts the cut edge material, which can prevent the cut material from being too long and tangling. Stacking facilitates later transfer and sorting. A closed cover 857 is provided on one side of the T-shaped plate 851. An isolation motor 855 is fixedly installed on the closed cover 857. The output end of the isolation motor 855 is fixedly connected to one of the first rollers 852. A transmission gear 856 is fixed to one end of the first roller 852. The transmission gear 856 meshes with a rotating gear. There are two sets of rotating gears, and the two sets of rotating gears mesh with each other. The rotating gear is rotatably connected to the T-shaped plate 851. The transmission gear 856 and the connecting gear are both located inside the closed cover 857. A side bracket 860 is provided on the support bucket 83. A support column 861 is slidably connected in the side bracket 860. The support columns 861 are symmetrically arranged on the cutting pressure plate 862. A support spring 863 is provided between the 62 and the side support 860. The support spring 863 is sleeved on the support column 861. During the casting process, the air pump 84 draws air to create negative pressure in the filter shell 87. External airflow enters the connecting shell 82 from the top support hopper 83. At this time, the edge material cut off by the trimming mechanism 7 will enter the connecting shell 82 under the action of unidirectional airflow and be blown onto the filter plate 86. The particulate impurities generated during the cutting process will pass through the filter plate 86 and be adsorbed and captured by the filter element embedded in the filter shell 87. During continuous production, the isolation motor 855 starts at regular intervals. During the rotation of one of the first rollers 852, the other first roller 852 will rotate synchronously in the opposite direction through two sets of meshing rotating gears.During the process, the connecting belt 853 rotates around the second roller 854 and the first roller 852. During operation, the cutting blade 859 on the isolation plate 858 flips and approaches the cutting pressure plate 862. Combined with the elastic support of the support spring 863 on the cutting pressure plate 862, the continuously cut edge material is cut off. The cut edge material enters the connecting shell 82. Subsequently, the isolation plate 858, located outside the connecting shell 82, gradually flips along with the connecting belt 853 into the support hopper 83, pushing the cut material into the connecting shell 82. As the isolation plate 858 continues to move, it pushes the cut edge material away from the filter plate 86 and into the upper part of the collection shell 88. Simultaneously, the isolation motor 855 stops operating, and the edge material, losing external force, falls directly to the bottom of the collection shell 88. Meanwhile, the isolation plate 858 remains at the edge of the connecting shell 82, separating the connecting shell 82 from the collection shell 88. This process continues intermittently, collecting the independently cut edge material into the collection shell 88.

[0039] Please see Figure 7 A casting and laminating method for producing PVC table mats includes the following steps:

[0040] Step 1, Extrusion Casting: The raw material of the PVC table mat is fed into the extruder 1. The extruder 1 melts and extrudes the raw material into the molding die 2 for initial molding. After initial molding, the table mat flows out from the bottom of the molding die 2 and falls. When falling, the output pump 43 outputs airflow through the jet nozzle 44 to adhere the table mat to the casting cooling roller 41. The casting cooling roller 41 rotates at low speed under the drive of the first motor reducer 45, so that the table mat is quickly cooled and shaped. Then, it passes over the peeling roller 46 to peel off the table mat from the casting cooling roller 41, and then passes over the auxiliary cooling roller 47 driven by the second motor reducer 48 for further cooling and complete shaping.

[0041] Step 2, hot pressing lamination: The fully shaped pad and the film on the feeding roller 51 pass through the hot pressing roller 52 and the glue roller 53 together. During the process, the hot pressing roller 52 provides heat to laminate the film onto the surface of the pad.

[0042] Step 3, winding correction: The third motor reducer 62 operates to provide winding power to the winding roller 61, thereby winding the composite film onto the winding roller 61. During the winding process, the first cylinder 72 drives the first bracket 73 to move, which can adjust the cutting width. The second cylinder 74 drives the second bracket 75 to move down, so that the cutting disc 77 contacts the table pad. In conjunction with the cutting motor 76 driving the rotation of the cutting disc 77, the cutting action is realized, and the excess edge material is cut off according to the required size.

[0043] Step 4, Waste Disposal: During the cutting process of the repair mechanism 7, the air pump 84 draws air to create negative pressure in the filter housing 87. The edge material cut off by the repair mechanism 7 will enter the connecting housing 82 under the action of unidirectional airflow and be blown onto the filter plate 86. During continuous production, the isolation motor 855 starts at regular intervals, causing the connecting belt 853 to rotate around the second roller 854 and the first roller 852. During this process, the cutting blade 859 on the isolation plate 858 moves closer to the cutting pressure plate 862. With the support spring 863 providing elastic support to the cutting pressure plate 862, the continuously cut edge material is cut off. After cutting, the isolation plate 858 continues to enter the connecting housing 82, pushing the cut edge material away from the filter plate 86 and into the upper part of the collection housing 88. At the same time, the isolation motor 855 stops running, and the edge material loses external force and falls directly to the bottom of the collection housing 88. Meanwhile, the isolation plate 858 stays at the edge of the connecting housing 82, separating the connecting housing 82 from the collection housing 88. After that, it continues to operate intermittently, collecting the independently cut edge material into the collection housing 88.

[0044] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.

7. A casting and laminating method for producing PVC table mats, based on the casting and laminating equipment for producing PVC table mats as described in claim 6, characterized in that, Includes the following steps: Step 1, Extrusion Casting: The raw material of the PVC table mat is fed into the extruder. The extruder melts and extrudes the raw material into the molding die for initial molding. After initial molding, the table mat flows out from the bottom of the molding die and falls. When falling, the output pump outputs air through the jet nozzle to stick the table mat to the casting cooling roller. The casting cooling roller rotates at low speed under the drive of the first motor reducer, so that the table mat is quickly cooled and shaped. Then, it passes over the peeling roller to peel the table mat off from the casting cooling roller, and then passes over the auxiliary cooling roller driven by the second motor reducer for further cooling and complete shaping. Step 2, hot pressing lamination: The fully shaped pad and the film on the feeding roller pass through the hot pressing roller and the glue roller together. During the process, the hot pressing roller provides heat to laminate the film onto the surface of the pad. Step 3, winding correction: The third motor reducer operates to provide winding power to the winding roller, thereby winding the composite film onto the winding roller. During the winding process, the first cylinder drives the first bracket to move and adjust the cutting width. The second cylinder drives the second bracket to move down, so that the cutting disc contacts the table. The cutting motor drives the cutting disc to rotate and realize the cutting action. The excess edge material is cut off according to the required size. Step 4, Waste Disposal: During the cutting process of the repair mechanism, the air pump draws air to create negative pressure in the filter housing. The edge material cut off by the repair mechanism will enter the connecting housing under the action of unidirectional airflow and be blown onto the filter plate by the airflow. During continuous production, the isolation motor starts at regular intervals, causing the connecting belt to rotate around the second roller and the first roller. During this process, the cutting blade on the isolation plate moves closer to the cutting pressure plate. With the support spring providing elastic support to the cutting pressure plate, the continuously cut edge material is cut off. After cutting, the isolation plate continues to enter the connecting housing, pushing the cut edge material away from the filter plate and into the upper part of the collection housing. At the same time, the isolation motor stops running, and the edge material loses external force and falls directly to the bottom of the collection housing. Meanwhile, the isolation plate stays at the edge of the connecting housing, separating the connecting housing from the collection housing. After that, it continues to run intermittently, collecting the independently cut edge material into the collection housing.
