Description

Technical Field

[0001] This utility model relates to the technical field of polyester resin production equipment, and in particular to a polyester resin cooling and sheeting machine. Background Technology

[0002] Polyester resins are a class of linear polymer compounds synthesized from polyols and polyacids through polycondensation reactions. They are divided into two categories: saturated polyester resins and unsaturated polyester resins, and are widely used in coatings, composite materials and other fields.

[0003] Polyester resin has a wide range of applications in industrial production. In its manufacturing process, cooling and sheet formation is an important step. In traditional polyester resin cooling and sheet formation machines, the height of the cooling roller is usually fixed and cannot be flexibly adjusted according to the characteristics of polyester resin and different production processes. This will affect the contact effect between polyester resin and cooling roller, thereby reducing the sheet formation quality and making it impractical. Therefore, it is necessary to redesign a polyester resin cooling and sheet formation machine to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a polyester resin cooling and sheeting machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A polyester resin cooling and sheeting machine includes a base plate. Two connecting pipes are fixedly installed on the upper surface of the base plate via a support plate. A discharge pipe is fixedly connected to the outer wall of the two connecting pipes. A discharge nozzle communicating with the interior is fixedly installed on the outer wall of the discharge pipe. A screw is rotatably installed on the upper surface of the base plate via a support frame. A first motor connected to the screw is fixedly installed on the upper surface of the support frame. A moving block is rotatably installed on the outer wall of the screw via a thread. A limit rod is fixedly installed inside the support frame. The limit rod slides through the moving block. A lifting plate is fixedly connected to the outer wall of the moving block via a connecting mechanism.

[0007] Two connecting plates are fixedly installed on the upper surface of the lifting plate. Rotating tubes are rotatably installed through the inner walls of both connecting plates. Hollow rollers are fixedly installed on the outer walls of both rotating tubes. Connecting sleeves are fixedly installed on the outer walls of both rotating tubes. A water inlet pipe is fixedly installed on the inner wall of one connecting sleeve, and a water outlet pipe is fixedly installed on the inner wall of the other connecting sleeve. A water tank is fixedly installed on the upper surface of the lifting plate. A water pump is fixedly installed on the upper surface of the water tank. The inlet pipe of the water pump extends into the water tank. The end of the inlet pipe is connected to the outlet of the water pump. The outlet pipe extends into the water tank. A second motor is fixedly installed on the outer wall of one of the connecting plates. The outer wall of the output shaft of the second motor is connected to the rotating tube on the same side through a transmission mechanism. An electric push rod is fixedly installed on the outer walls of both connecting plates through a mounting frame. A scraper is fixedly installed on the telescopic end of the electric push rod through a fixing mechanism. A collection frame is slidably installed on the upper surface of the lifting plate.

[0008] Preferably, the connecting mechanism includes two connecting rods fixedly installed on the outer wall of the movable block, and the ends of the two connecting rods are fixedly connected to the upper surface of the lifting plate.

[0009] Preferably, the transmission mechanism includes pulleys fixedly installed on the output shaft of the second motor and the outer wall of the rotating tube, and the two pulleys are connected by a belt for transmission.

[0010] Preferably, the fixing mechanism includes a fixing plate fixedly installed at the telescopic end of the electric push rod, and the bottom wall of the fixing plate is fixedly connected to the upper end face of the scraper.

[0011] Preferably, a cooler is fixedly installed on the outer wall of the water tank, and the cold end of the cooler is installed on the inner wall of the water tank.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting up components such as a screw, a moving block, and a lifting plate, the first motor drives the screw to rotate, and the limit rod restricts the moving block to move linearly along the screw axis. The lifting plate is raised and lowered through the connecting rod. This height adjustment function allows the hollow roller to be precisely positioned as needed, so that the contact state between the polyester resin and the hollow roller is optimal, significantly improving cooling efficiency and sheet quality.

[0014] 2. By setting up components such as electric push rods and fixed plates, when it is necessary to adjust the thickness of the agglomerates, the operator only needs to control the extension and retraction of the electric push rods. The electric push rods will push the fixed plates and the scrapers installed on them closer to or further away from the hollow rollers, thereby achieving precise control of the thickness of the agglomerates.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-7 A polyester resin cooling and sheeting machine includes a base plate 1. Two connecting pipes 3 are fixedly installed on the upper surface of the base plate 1 via a support plate 2. The outer walls of the two connecting pipes 3 are fixedly connected to a discharge pipe 4. A discharge nozzle communicating with the interior is fixedly installed on the outer wall of the discharge pipe 4. A screw 6 is rotatably installed on the upper surface of the base plate 1 via a support frame 5. A first motor 7 connected to the screw 6 is fixedly installed on the upper surface of the support frame 5. A moving block 9 is rotatably installed on the outer wall of the screw 6 via a thread. A limit rod 8 is fixedly installed inside the support frame 5. The limit rod 8 slides through the moving block 9. A lifting plate 11 is fixedly connected to the outer wall of the moving block 9 via a connecting mechanism.

[0025] Two connecting plates 12 are fixedly installed on the upper surface of the lifting plate 11. Rotating pipes 13 are rotatably installed through the inner walls of both connecting plates 12. Hollow rollers 14 are fixedly installed on the outer walls of both rotating pipes 13. Connecting sleeves 15 are fixedly installed on the outer walls of both rotating pipes 13. A water inlet pipe 16 is fixedly installed on the inner wall of one connecting sleeve 15, and a water outlet pipe 17 is fixedly installed on the inner wall of the other connecting sleeve 15. A water tank 18 is fixedly installed on the upper surface of the lifting plate 11, and a water pump 19 is fixedly installed on the upper surface of the water tank 18. The inlet pipe extends into the water tank 18, the end of the inlet pipe 16 is connected to the outlet of the water pump 19, and the outlet pipe 17 extends into the water tank 18. A second motor 21 is fixedly installed on the outer wall of one of the connecting plates 12. The outer wall of the output shaft of the second motor 21 is connected to the rotating pipe 13 on the same side through a transmission mechanism. The outer walls of the two connecting plates 12 are fixedly installed with an electric push rod 24 through a mounting frame 23. A scraper 26 is fixedly installed on the telescopic end of the electric push rod 24 through a fixing mechanism. A collection frame 27 is slidably installed on the upper surface of the lifting plate 11.

[0026] Furthermore, the setting of the limiting rod 8 plays a key limiting and guiding role for the moving block 9, ensuring that the moving block 9 can only move in a straight line along the axis of the screw 6 when the screw 6 rotates, avoiding the moving block 9 from rotating with the screw 6, thereby ensuring the stability and accuracy of the lifting plate 11 during the lifting process.

[0027] The connecting mechanism includes two connecting rods 10 fixedly installed on the outer wall of the movable block 9, and the ends of the two connecting rods 10 are fixedly connected to the upper end face of the lifting plate 11.

[0028] Furthermore, the connecting rod 10 is made of high-strength material, with good rigidity and toughness, and can withstand the weight of the lifting plate 11 and its components, ensuring that the movement of the moving block 9 can be accurately transmitted to the lifting plate 11, thereby achieving effective adjustment of the height of the hollow roller 14.

[0029] The transmission mechanism includes pulleys 22 that are fixedly installed on the output shaft of the second motor 21 and the outer wall of the rotating tube 13. The two pulleys 22 are connected by a belt for transmission.

[0030] Furthermore, the pulley 22 and belt transmission method has the advantages of simple installation and convenient maintenance, and can buffer the impact force during the transmission process to a certain extent, protecting components such as the motor and rotating tube 13.

[0031] The fixing mechanism includes a fixing plate 25 fixedly installed at the telescopic end of the electric push rod 24, and the bottom wall of the fixing plate 25 is fixedly connected to the upper end face of the scraper 26.

[0032] Furthermore, the fixed plate 25 is securely connected to the electric push rod 24 and the scraper 26, which ensures that the scraper 26 moves and works stably under the drive of the electric push rod 24. This fixing method makes the position adjustment of the scraper 26 more precise and can better adapt to different production processes and product quality requirements.

[0033] A cooler 20 is fixedly installed on the outer wall of the water tank 18, and the cold end of the cooler 20 is installed on the inner wall of the water tank 18.

[0034] Furthermore, the cooler 20 can precisely control the temperature of the coolant in the water tank 18, keeping it within a suitable range. Through the efficient cooling effect of the cooler 20, the coolant can continuously remove the heat from the polyester resin on the surface of the hollow roller 14, ensuring the stability and consistency of the cooling effect, thereby improving the quality and production efficiency of the cooled polyester resin sheets.

[0035] When this utility model is in use, the cold end of the cooler 20 can pre-cool the cooling water inside the water tank 18. The water pump 19 pumps the cooled water into the internal cooling channel of the hollow roller 14 through the water inlet pipe 16. When the surface temperature of the hollow roller 14 drops, the polyester resin is evenly transported to the inside of the discharge pipe 4 through the two connecting pipes 3, and then flows out from the discharge nozzle of the discharge pipe 4, evenly covering the surface of the hollow roller 14. At this time, the cooling water can exchange heat with the polyester resin attached to the surface of the hollow roller 14. The heated cooling water flows back to the water tank 18 through the water outlet pipe 17 and is cooled down again by the cooler 20, forming a highly efficient circulating cooling system.

[0036] Meanwhile, the second motor 21 drives the rotating tube 13 and the hollow roller 14 to rotate via the pulley 22 and belt, so that the polyester resin moves at a uniform speed on the roller surface and is fully cooled. When the polyester resin reaches a suitable degree of curing, the electric push rod 24 adjusts the position of the scraper 26 according to the set parameters, and precisely scrapes the cooled flakes off the roller surface, which fall into the collection frame 27 that is slidably set below for collection. In addition, if different specifications of polyester resin products are produced, the first motor 7 can be started to drive the screw 6 to rotate. Under the restriction of the limit rod 8, the moving block 9 drives the lifting plate 11 to rise and fall smoothly through the connecting rod 10, so as to realize the flexible adjustment of the height of the hollow roller 14 and meet the diverse production needs. When a thicker flake is required, the electric push rod 24 retracts, driving the fixed plate 25 and the scraper 26 away from the surface of the hollow roller 14, so that more polyester resin is cooled and accumulated on the roller surface. If a thinner flake is required, the electric push rod 24 is extended to push the scraper 26 closer to the hollow roller 14, so as to precisely control the thickness of the flake.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
