Description

Technical Field

[0001] This invention relates to the field of plastic product processing technology, specifically to a production equipment and method for composite plastic products. Background Technology

[0002] Plastic flooring is made of PVC as the main raw material, with the addition of fillers, plasticizers, stabilizers, colorants and other auxiliary materials. In the manufacturing process, most of the materials are hot-pressed together to form a composite plastic board.

[0003] After the plastic sheets are hot-pressed and laminated, they are transported to the next process. Because the hot-pressing process leaves the plastic sheets with a certain temperature, they tend to stick to the conveying device, causing inconvenience to the production process. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a production equipment and method for composite plastic products, which solves the problem that plastic sheets tend to stick to the conveying device during the hot-pressing composite process, causing inconvenience to production operations.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a production equipment for composite plastic products, comprising an extrusion and lamination mechanism, a conveying device, a support belt, and a heating device. The extrusion and lamination mechanism is installed on the upper side of the inlet end of the conveying device. A support belt is sleeved on the outer side of the conveyor belt of the conveying device. The support belt forms a rectangular shape with the support roller of the conveying device through idler rollers. A heating device is installed on the lower side of the conveying device. The section where the support belt separates from the conveyor belt of the conveying device passes through the heating device. A cooling device is installed on the upper side of the outlet end of the conveying device. An infrared shaping device is installed on the upper side of the conveying device between the extrusion and lamination mechanism and the cooling device. Multiple convex strips extend equidistantly from the outer side of the support belt.

[0006] Preferably, the extrusion compounding mechanism includes a housing, an extrusion assembly is installed in the middle of the housing, a drive assembly is installed on one side of the extrusion assembly, heating chambers are provided on both sides of the housing located on the extrusion assembly, heaters are installed in the heating chambers, a mounting base is fixedly connected to the upper side of the middle of the housing, a feeding channel is formed between the two sides of the mounting base and the housing, and a coating mechanism is installed on the top wall of the feeding channel.

[0007] Preferably, the extrusion assembly includes pressure rollers, and multiple pressure rollers are rotatably connected to the housing. The pressure rollers on both sides are arranged vertically corresponding to the two feeding channels on both sides. The multiple pressure rollers are arranged in a V shape. The inlet end of the extrusion assembly is located on the lower side of the intersection of the two feeding channels, and the drive assembly is located at the end of the upper pressure roller.

[0008] Preferably, the drive assembly includes a motor, the output end of which is fixedly connected to a drive gear, the drive gear meshing with a first driven gear, the first driven gear meshing with a second driven gear, the middle part of one side of the first driven gear and the second driven gear being fixedly connected to the ends of two upper pressure rollers respectively, and the motor being fixedly connected to a part of the outer wall of the housing via a mounting plate.

[0009] Preferably, the coating mechanism includes a nozzle and a brush plate, the nozzle being fixedly connected to a location on the top wall of the feed channel, and the brush plate being fixedly connected to a location on the top wall of the feed channel near the bottom side.

[0010] Preferably, a baffle is fixedly connected to the top wall of the feed channel above the nozzle.

[0011] Another object of the present invention is to provide a method for producing composite plastic products using equipment, comprising the following steps:

[0012] S1. First, preheat the two plastic sheets to be laminated, and then simultaneously put the two plastic sheets to be laminated into the feeding channels on both sides of the extrusion lamination mechanism.

[0013] S2. During the process, adhesive is sprayed onto the surface of the plastic sheet through the nozzle. Then the plastic sheet continues to move downwards, and the adhesive is evenly applied by the brush.

[0014] S3. When the bottom ends of the two plastic sheets come into contact with the top pressure roller of the extrusion assembly, the motor output drives the drive gear to rotate. The drive gear meshes with the first driven gear, and the first driven gear meshes with the second driven gear. This causes the first and second driven gears to rotate in opposite directions through the motor output, which in turn drives the two upper pressure rollers to rotate relative to each other. The drive assembly drives the two upper pressure rollers to rotate in opposite directions, thereby causing the two plastic sheets to be extruded and compounded by the V-shaped pressure rollers on both sides. During the extrusion process, the heater keeps the inside of the box at a certain temperature. Afterward, the extruded and compounded plastic sheets fall from the bottom of the mechanism onto the conveying device.

[0015] S4. The plastic sheet is conveyed by the conveying device and shaped by the infrared shaping device, and then cooled by the cooling device.

[0016] During the conveying process in steps S5 and S4, the heating device allows the support belt to move into the heating device along with the conveying device. The heating device circulates heat on the support belt, keeping its temperature within a certain range. This effectively prevents the extruded and laminated plastic sheet from sticking to the surface of the support belt. Furthermore, the multiple protrusions on the outer side of the support belt reduce the contact area between the plastic sheet and the support belt, further preventing the plastic sheet from sticking to the surface of the support belt.

[0017] This invention provides a production equipment and method for composite plastic products. It has the following beneficial effects:

[0018] This invention provides a support belt fitted over the outside of the conveyor belt of a conveyor device that transports composite plastic sheets after extrusion lamination. This prevents the extruded plastic sheets from sticking to the surface of the conveyor belt during transport. Simultaneously, a heating device allows the support belt to move into the heating device as the conveyor transports the sheets. The heating device cyclically heats the support belt, maintaining its temperature within a certain range, effectively preventing the extruded plastic sheets from sticking to the support belt surface. Furthermore, multiple protrusions on the outside of the support belt reduce the contact area between the plastic sheet and the support belt, further preventing the plastic sheet from sticking to the support belt surface.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1:

[0028] like Figure 1-6 As shown, this embodiment of the invention provides a production equipment for composite plastic products, including an extrusion composite mechanism 1, a conveying device 6, a support belt 7, and a heating device 8. The extrusion composite mechanism 1 is installed on the upper side of the inlet end of the conveying device 6. After the extrusion composite mechanism 1 extrudes and composites two plastic sheets, they fall onto the conveying device 6. The support belt 7 is sleeved on the outer side of the conveyor belt of the conveying device 6. The support belt 7 prevents the extruded plastic sheets from sticking to the surface of the conveyor belt of the conveying device 6. The support belt 7 forms a rectangular shape with the support roller of the conveying device 6 through the idler roller 701. The heating device 8 is installed on the lower side of the conveying device 6. The section of the support belt 7 that separates from the conveyor belt of the conveying device 6 passes through the heating device 8. The heating device 8 allows the support belt 7 to move into the heating device 8 as it is conveyed by the conveying device 6. The overheating device 8 circulates heat to the support belt 7, keeping its temperature within a certain range to effectively prevent the extruded plastic sheet from sticking to the surface of the support belt 7. A cooling device 10 is installed on the upper side of the discharge end of the conveying device 6. The extruded plastic sheet is conveyed to the cooling device 10 through the conveying device 6 for cooling. An infrared shaping device 9 is installed on the upper side of the conveying device 6 between the extrusion and lamination mechanism 1 and the cooling device 10. Before being cooled by the cooling device 10, the extruded plastic sheet needs to be shaped by the infrared shaping device 9. Multiple protrusions 702 are equidistantly arranged on the outer side of the support belt 7. The multiple protrusions 702 on the outer side of the support belt 7 reduce the contact area between the plastic sheet and the support belt 7, thereby further preventing the plastic sheet from sticking to the surface of the support belt 7.

[0029] By attaching a support belt 7 to the outside of the conveyor belt of the conveyor device 6 that transports the composite plastic sheet after processing by the extrusion compounding mechanism 1, the plastic sheet after extrusion compounding can be prevented from sticking to the surface of the conveyor belt during the transport process of the conveyor device 6. At the same time, the support belt 7 can be moved into the heating device 8 along with the conveyor device 6 during transport. The heating device 8 circulates the heating of the support belt 7, so that the temperature of the support belt 7 is always kept within a certain range, which effectively prevents the plastic sheet after extrusion compounding from sticking to the surface of the support belt 7. Furthermore, the multiple protrusions 702 provided on the outside of the support belt 7 reduce the contact area between the plastic sheet and the support belt 7, thereby further preventing the plastic sheet from sticking to the surface of the support belt 7.

[0030] The extrusion laminating mechanism 1 includes a housing 101, an extrusion assembly 2 installed in the middle of the housing 101, a drive assembly 3 installed on one side of the extrusion assembly 2, heating chambers 102 on both sides of the housing 101 located on the extrusion assembly 2, and heaters 4 installed in each heating chamber 102. A mounting base 103 is fixedly connected to the upper middle part of the housing 101, and a feeding channel 104 is formed between the two sides of the mounting base 103 and the housing 101. A coating mechanism 5 is installed on the top wall of the feeding channel 104. Two plastic sheets to be laminated enter the extrusion assembly 2 through the feeding channels 104 on both sides. During the entry process, adhesive is evenly applied to the joint of the two plastic sheets by the coating mechanism 5. Then, the two plastic sheets are extruded and laminated by the extrusion assembly 2 to form a composite plastic product.

[0031] The extrusion assembly 2 includes pressure rollers 201, which are rotatably connected to the housing 101. The two pressure rollers 201 are arranged vertically corresponding to the two feed channels 104. The multiple pressure rollers 201 are arranged in a V shape. The inlet end of the extrusion assembly 2 is located on the lower side of the intersection of the two feed channels 104. The drive assembly 3 is located at the end of the upper pressure roller 201. The drive assembly 3 drives the two upper pressure rollers 201 to rotate in opposite directions, thereby driving the two plastic sheets to be extruded and compounded by the two V-shaped pressure rollers 201.

[0032] The drive assembly 3 includes a motor 301. A drive gear 302 is fixedly connected to the output end of the motor 301. The drive gear 302 meshes with a first driven gear 303. The first driven gear 303 meshes with a second driven gear 304. The middle part of one side of the first driven gear 303 and the second driven gear 304 are respectively fixedly connected to the ends of the two upper pressure rollers 201. The motor 301 is fixedly connected to a part of the outer wall of the housing 101 through a mounting plate 305. The motor 301 drives the drive gear 302 to rotate. The drive gear 302 meshes with the first driven gear 303, and the first driven gear 303 meshes with the second driven gear 304. Thus, the motor 301 drives the first driven gear 303 and the second driven gear 304 to rotate in opposite directions, thereby driving the two upper pressure rollers 201 to rotate relative to each other.

[0033] The coating mechanism 5 includes a nozzle 501 and a brush plate 502. The nozzle 501 is fixedly connected to a part of the top wall of the feed channel 104, and the brush plate 502 is fixedly connected to the top wall of the feed channel 104 near the bottom side. The nozzle 501 sprays adhesive onto the surface of the plastic sheet, and then the plastic sheet continues to move downward, and the brush plate 502 spreads the adhesive evenly.

[0034] A stop 503 is fixedly connected to the top wall of the feed channel 104 above the nozzle 501. The stop 503 prevents the plastic sheet from contacting the nozzle 501 when it enters the feed channel 104, thereby preventing damage to the nozzle 501.

[0035] Example 2:

[0036] This embodiment provides a production method for composite plastic product manufacturing equipment, including the following steps:

[0037] S1. First, preheat the two plastic sheets to be laminated, and then simultaneously put the two plastic sheets to be laminated into the feeding channels 104 on both sides of the extrusion lamination mechanism 1.

[0038] S2. During the entry process, adhesive is sprayed onto the surface of the plastic sheet through the nozzle 501. Then the plastic sheet continues to move downwards, and the adhesive is evenly applied through the brush plate 502.

[0039] S3. When the bottom ends of the two plastic sheets come into contact with the top pressure roller 201 of the extrusion assembly 2, the motor 301 outputs to drive the drive gear 302 to rotate. The drive gear 302 meshes with the first driven gear 303, and the first driven gear 303 meshes with the second driven gear 304. This causes the first driven gear 303 and the second driven gear 304 to rotate in opposite directions through the output of the motor 301, which in turn drives the two upper pressure rollers 201 to rotate relative to each other. The drive assembly 3 drives the two upper pressure rollers 201 to rotate in opposite directions, thereby driving the two plastic sheets to be extruded and compounded by the V-shaped pressure rollers 201 on both sides. During the extrusion process, the heater 4 heats the inside of the box 101 to maintain a certain temperature. Then, the extruded and compounded plastic sheets fall from the bottom of the mechanism onto the conveying device 6.

[0040] S4. The plastic sheet is conveyed by the conveying device 6 and shaped by the infrared shaping device 9, and then cooled by the cooling device 10.

[0041] During the conveying process in steps S5 and S4, the heating device 8 allows the support belt 7 to move into the heating device 8 along with the conveying device 6. The heating device 8 cyclically heats the support belt 7, keeping its temperature within a certain range. This effectively prevents the extruded and laminated plastic sheet from sticking to the surface of the support belt 7. Furthermore, the multiple protrusions 702 on the outer side of the support belt 7 reduce the contact area between the plastic sheet and the support belt 7, further preventing the plastic sheet from sticking to the surface of the support belt 7.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
