Description

Technical Field

[0001] This utility model relates to the field of PET processing, and in particular to a shaping device for improving the flatness of PET sheets. Background Technology

[0002] PET resin is a crystalline material. In the process of producing PET sheets, in order to obtain transparent PET sheets, the PET sheet preform needs to be rapidly cooled after demolding to freeze the PET molecular chains and prevent crystallization, thereby obtaining transparent sheets.

[0003] Chinese patent CN221873157U discloses a device for improving the flatness of PET sheets. The device includes a side support, a limiting frame, a servo motor, a bidirectional screw, leveling feet, a second slot, and a lead screw slide. The bottom end of the second slot is arc-shaped and abuts against the top of the sheet. By starting the servo motor, the bidirectional screw and the lead screw slide can be rotated, thereby driving the two leveling feet to move towards each other inside the second slot. This causes the two edges of the sheet to be stretched to both sides simultaneously through friction, thereby further improving the flatness of the sheet.

[0004] Taking the aforementioned patent as an example, traditional PET sheet flattening equipment usually uses friction to trim PET sheets. However, the device in the aforementioned patent exposes the trimmed sheet directly to the air after completing the friction trimming work, which may cause the PET sheet to expand and contract rapidly under the contact of oxygen, inevitably causing the PET surface to crack. Utility Model Content

[0005] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a shaping device for improving the flatness of PET sheets.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a shaping device for improving the flatness of PET sheets, comprising a mounting base, a drive motor, a transmission roller, a gantry frame, a drive cylinder, a mounting frame, an extrusion roller, a stabilizing device, and a mounting shaft. The drive motor is mounted at the rear end of the mounting base, and the drive motor is connected to the rear end of the transmission roller via a coupling. The left end of the mounting base is nested inside the outer side of the transmission roller. The gantry frame is fixed to the top of the mounting base, and the drive cylinder is fixed to the inner top end of the gantry frame. The drive cylinder is connected to the outer side of the mounting frame. The inner side of the mounting frame... An installation shaft is provided, and the extrusion roller is installed on the outside of the installation shaft. The stabilizing device is fixed to the top of the mounting base and is located at the left end of the extrusion roller. The stabilizing device includes a cooling shroud, a temperature controller, a cold air pump, a condensation pipe, a gas concentrator, and a driver. A detection shroud is installed at the right end of the cooling shroud. The temperature controller is connected to the right end of the cold air pump, which is installed inside the cooling shroud. The left end of the cold air pump is connected to the condensation pipe. The gas concentrator is movably fitted to the bottom of the condensation pipe and is installed at the right end of the driver. The driver is fixed to the left end of the cooling shroud.

[0007] As a further embodiment of this utility model, the driver includes a housing, a servo motor, a swing arm, and a mounting sleeve. The housing is fixed to the left end of the cooling cover, the servo motor is mounted on the left end of the swing arm, and the right end of the swing arm is fitted with a mounting sleeve. The mounting sleeve is fixed to the left end of the air-gathering nozzle by a fixing stud.

[0008] As a further embodiment of this invention, a rectangular groove is provided at the bottom of the cooling cover to ensure that the sheet can move normally from the bottom of the cooling cover.

[0009] As a further embodiment of this invention, the bottom of the condensation pipe is provided with multiple sets of frustum-shaped nozzles, thereby ensuring that the gas output from the condensation pipe can uniformly cool and shape the sheet.

[0010] As a further embodiment of this invention, the cross-section of the condensation pipe is a spiral structure, which facilitates the flow of air inside the condensation pipe.

[0011] As a further embodiment of this utility model, a guide rail is provided on the inner left end of the cooling cover, and the left end of the cooling cover slides in conjunction with the right end of the driver.

[0012] As a further embodiment of this utility model, the right end of the mounting sleeve is annular and matches the left end of the air-gathering nozzle, ensuring that the mounting sleeve can be stably embedded into the left end of the air-gathering nozzle and play a role in fixing and transmitting the air-gathering nozzle.

[0013] Compared with the prior art, this utility model provides a shaping device for improving the flatness of PET sheets, which has the following beneficial effects:

[0014] 1. This utility model is equipped with a stabilizing device. By starting the cold air pump to introduce gas, and then starting the temperature controller to heat and cool the gas, the treated gas can flow into the interior of the condensing pipe. The condensing pipe, with its own spiral structure, prevents the gas from changing too quickly. The gas concentrator is evenly distributed at the bottom of the condensing pipe, so that the gas can be sprayed downwards evenly without uneven gas distribution. The auxiliary gas sprayed by the gas concentrator can quickly assist the newly shaped sheet in taking off, allowing the sheet to adapt to the external environment. In this way, the stabilizing device generates auxiliary gas and blows it onto the sheet, allowing the sheet to quickly adapt to the external temperature, thereby avoiding the problem of the sheet surface cracking caused by external environmental factors.

[0021] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0022] Please see Figures 1-2 In the embodiments of this utility model:

[0023] A shaping device for improving the flatness of PET sheets includes a mounting base 1, a drive motor 2, a transmission roller 3, a gantry frame 4, a drive cylinder 5, a mounting frame 6, a squeeze roller 7, a stabilizing device 8, and a mounting shaft 9. The drive motor 2 is mounted at the rear end of the mounting base 1 and is connected to the rear end of the transmission roller 3 via a coupling. The left end of the mounting base 1 is nested on the outer side of the transmission roller 3. The gantry frame 4 is fixed to the top of the mounting base 1. The drive cylinder 5 is fixed to the inner top end of the gantry frame 4 and is connected to the outer side of the mounting frame 6. The mounting shaft 9 is provided inside the mounting frame 6. The squeeze roller 7 is mounted on the outer side of the mounting shaft 9. The stabilizing device 8 is fixed to the top of the mounting base 1 and is located at the left end of the squeeze roller 7.

[0024] refer to Figures 3-4 In the embodiments of this utility model:

[0025] The stabilizing device 8 includes a cooling cover 81, a temperature controller 82, a cold air pump 83, a condensation pipe 84, a gas concentrator 85, and a driver 86. A detection cover 82 is installed on the right end of the cooling cover 81. The temperature controller 82 is connected to the right end of the cold air pump 83. The cold air pump 83 is installed inside the cooling cover 81. The left end of the cold air pump 83 is connected to the condensation pipe 84. The gas concentrator 85 is movably fitted to the bottom of the condensation pipe 84. The gas concentrator 85 is installed on the right end of the driver 86. The driver 86 is fixed to the left end of the cooling cover 81.

[0026] In this embodiment, the following features are prioritized: a rectangular groove is provided at the bottom of the cooling cover 81 to ensure that the sheet can move normally from the bottom of the cooling cover 81; multiple sets of frustum-shaped nozzles are provided at the bottom of the condensing pipe 84 to ensure that the gas output by the condensing pipe 84 can uniformly cool and shape the sheet; the cross-section of the condensing pipe 84 is a spiral structure to facilitate airflow inside the condensing pipe 84; a guide rail is provided at the left end of the interior of the cooling cover 81, and the left end of the cooling cover 81 slides in conjunction with the right end of the driver 86.

[0027] refer to Figure 5 In the embodiments of this utility model:

[0028] The driver 86 includes a housing 861, a servo motor 862, a swing arm 863, and a mounting sleeve 864. The housing 861 is fixed to the left end of the cooling cover 81. The servo motor 862 is mounted on the left end of the swing arm 863. The right end of the swing arm 863 is fitted with the mounting sleeve 864. The mounting sleeve 864 is fixed to the left end of the air nozzle 85 by a fixing stud. The right end of the mounting sleeve 864 is annular and matches the left end of the air nozzle 85, ensuring that the mounting sleeve 864 can be stably embedded in the left end of the air nozzle 85, thus playing a role in fixing and transmitting power to the air nozzle 85.

[0029] refer to Figures 1-5When in use, place the mounting base 1 horizontally on the ground to support the equipment;

[0030] The sheet is placed from the right side of the mounting bracket 6. The transmission motor 2 is started and the transmission roller 3 is driven to rotate through the coupling. The transmission roller 3 can move the sheet under the gantry 4 by friction with the sheet.

[0031] Subsequently, the mounting frame 6 is pushed downward by the transmission cylinder 5, so that the extrusion roller 7 installed inside the mounting frame 6 can extrude and roll friction on the sheet, thereby completing the shaping work of the sheet.

[0032] Furthermore, by starting the cold air pump 83 to introduce gas, and then starting the temperature controller 82 to heat and cool the gas, the treated gas can flow into the interior of the condenser pipe 84. The condenser pipe 84, with its own spiral structure, prevents the gas from changing too quickly. The gas concentrator 85 is evenly distributed at the bottom of the condenser pipe 84, so that the gas concentrator 85 can spray the gas evenly downwards, without uneven gas distribution.

[0033] Simultaneously, the servo motor 862 drives the swing arm 863 to swing up and down, enabling the mounting sleeve 864 to move up and down with the air-gathering nozzle 85. This allows the air-gathering nozzle 85 to be attached to the top of the sheet, enabling the air-gathering nozzle 85 to spray auxiliary gas to quickly assist the newly shaped sheet in taking off. This allows the sheet to adapt to the external environment. Furthermore, the stabilizing device 8 generates auxiliary gas and blows it onto the sheet, allowing the sheet to quickly adapt to the external temperature and thus preventing the sheet surface from cracking due to external environmental factors.
