Description

Technical Field

[0001] This utility model belongs to the field of PET tape processing technology, specifically relating to a PET tape surface matte treatment device. Background Technology

[0002] PET strapping is a process of making PET strapping using polyethylene terephthalate (PET) as raw material. First, the raw material is dried and dehumidified, then heated and melted in an extruder, and extruded into a strip-shaped preform through a die. The preform is then stretched longitudinally to improve its strength and toughness, followed by heat setting to prevent shrinkage, and finally cooled and cut into finished products of different specifications.

[0003] Matte finishing in PET tape processing is a step designed to meet practical usage scenarios and appearance requirements. This treatment reduces the light reflectivity of the tape surface, preventing glare in brightly lit environments such as warehouses and workshops, ensuring clear vision for operators, and reducing operational errors caused by visual interference. Simultaneously, the matte finish increases the microscopic roughness of the tape surface, enhancing friction and effectively preventing slippage and misalignment during packaging, ensuring greater stability during machine transport or manual bundling.

[0004] While existing PET belt surface matte treatment equipment can also achieve matte treatment of PET belt surface, the sanding roller and heating system are integrated together. Therefore, whenever the sanding roller needs to be replaced or repaired, a lot of time is wasted in disassembling or installing it, which will cause serious inconvenience to the workers and reduce the processing efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a device for matte surface treatment of PET tapes to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PET tape surface matte treatment device, comprising a treatment box, the interior of which is provided with a treatment cavity, and a plurality of conveying rollers symmetrically distributed on the left and right sides are rotatably connected inside the treatment cavity. A hydraulic cylinder is fixedly connected to the top of the treatment box, the telescopic end of which penetrates through the upper surface of the treatment cavity and is fixedly connected to a support frame. A frosting roller is mounted on the side of the support frame via a connecting assembly. A support platform is fixedly connected to the lower surface inside the treatment cavity, and a pair of support rollers are mounted inside the support platform via an adjusting assembly. The connecting assembly includes a support base fixedly connected to the side of the support frame, a resistance heating rod fixedly mounted on the side of the support base, a connecting ring rotatably connected to the side surface of the support base via a bearing, a locking block fixedly connected to the side of the connecting ring, a thread one on the front of the locking block and located on the side of the connecting ring, and a thread two at the opening of the inner cavity of the frosting roller.

[0007] In a preferred embodiment, the adjustment assembly includes an adjustment cavity formed inside the support platform, and a limiting groove is formed on the lower surface inside the adjustment cavity. A bidirectional lead screw is rotatably connected inside the limiting groove via a bearing.

[0008] In a preferred embodiment, the adjustment assembly further includes a pair of movable frames slidably connected inside the adjustment cavity. The movable frames are U-shaped, and the bottom of the pair of movable frames is provided with a protrusion. The pair of movable frames are threadedly connected to a bidirectional lead screw through the protrusion. The protrusion is adapted to the shape of the limiting slide groove. A servo motor is fixedly installed on the right side of the support platform.

[0009] In a preferred embodiment, the processing chamber has entrances and exits on the left and right sides, and an observation port is provided at the front end of the processing chamber, with a door hinged inside the observation port.

[0010] In a preferred embodiment, a support leg is fixedly connected to the bottom of the processing box, and an anti-slip pad is fixedly connected to the bottom of the support leg.

[0011] In a preferred embodiment, the inner cavity of the grinding roller is filled with a heat-insulating filler, which is in contact with the outer surface of the resistance heating rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention features two pairs of symmetrically distributed conveyor rollers that limit the conveying of the PET belt from both sides, effectively preventing belt misalignment and wrinkles during transport and ensuring conveying stability. The L-shaped support frame slides along the gap between the support platform and the processing chamber, restricting its movement and ensuring the sanding roller is precisely aligned with the lower support roller, preventing uneven matte finishing of the PET belt due to roller misalignment. A resistance heating rod heats the sanding roller, enhancing the interaction between the roller and the PET belt surface, reducing uneven scratches, and improving the quality and efficiency of the matte finishing process. The hexagonal locking block allows for easy wrench fixing of the connecting ring, preventing it from rotating synchronously with the sanding roller during installation, reducing installation difficulty. The matching thread 1 and thread 2 ensure a secure installation of the sanding roller and facilitates easy disassembly and replacement of worn rollers, improving work efficiency.

[0013] This utility model features an adjustment component that uses a servo motor to drive a bidirectional lead screw to rotate. During rotation, the lead screw connects to the moving frame via a threaded connection and adapts to the shape of the protrusion and the limiting groove, thereby causing a pair of moving frames to move relative to each other. This allows for adjustment of the distance between a pair of support rollers, improving adaptability to grinding rollers of different radii and facilitating the matching of grinding rollers of different sizes. This effectively enhances practicality and convenience. Attached Figure Description

[0016] The present invention will be further described below with reference to the embodiments.

[0017] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0018] Please see Figure 1 - Figure 4 This utility model provides a matte surface treatment device for PET strips, including a treatment box 1. The treatment box 1 has a treatment cavity 2 inside. Several conveyor rollers 3, symmetrically distributed left and right, are rotatably connected inside the treatment cavity 2. One pair of conveyor rollers 3 are located above the side wall of the treatment cavity 2, and another pair of conveyor rollers 3 are located below the side wall of the treatment cavity 2. A hydraulic cylinder 4 is fixedly connected to the top of the treatment box 1. The telescopic end of the hydraulic cylinder 4 penetrates the upper surface of the treatment cavity 2 and is fixedly connected to a support frame 5. The support frame 5 is L-shaped, and its longitudinal end is slidably connected in the gap formed between a support platform 7 and the treatment cavity 2. A frosting roller 6 is installed on the side of the support frame 5 via a connecting assembly. A support platform 7 is fixedly connected to the lower surface inside the treatment cavity 2. A pair of support rollers 8 are installed inside the support platform 7 via an adjusting assembly, and the pair of support rollers 8 are located directly below the frosting roller 6. The connecting assembly includes a fixed connecting... A support base 501 is attached to the side of the support frame 5. The support base 501 is electrically connected to the resistance heating rod 502 via a wire. The resistance heating rod 502 is fixedly installed on the side of the support base 501, which can heat the sanding roller 6, thereby improving the quality and efficiency of the matte treatment of the PET belt surface. A connecting ring 503 is rotatably connected to the side surface of the support base 501 via a bearing. A locking block 504 is fixedly connected to the side of the connecting ring 503. The locking block 504 is hexagonal, which makes it easy for the operator to use a wrench to lock the connecting ring 503 and fix it. A thread 1 505 is provided in front of the locking block 504 and on the side of the connecting ring 503. A thread 2 506 is provided at the opening of the inner cavity of the sanding roller 6. The thread 1 505 and the thread 2 506 are adapted to each other, and the sanding roller 6 is threadedly connected to the connecting ring 503 through the adaptation of the thread 1 505 and the thread 2 506.

[0019] This invention, by designing the conveyor rollers 3 as two pairs symmetrically distributed vertically, can limit the conveying of the PET belt from both the upper and lower sides, effectively preventing the PET belt from shifting or wrinkling during conveying and ensuring conveying stability; the support frame 5 adopts an L-shaped structure and slides along the gap between the support platform 7 and the processing chamber 2, which can limit the movement direction of the support frame 5 and ensure that the sanding roller 6 can be accurately aligned with the support roller 8 below, avoiding uneven matte treatment of the PET belt due to the positional deviation of the sanding roller 6; the resistance heating rod 502 heats the sanding roller 6, which can improve the interaction effect between the sanding roller 6 and the PET belt surface, reduce the unevenness of scratches on the PET belt surface, and thus improve the quality and efficiency of matte treatment; the locking block 504 is hexagonal, which makes it convenient for workers to fix the connecting ring 503 with a wrench, and prevents the connecting ring 503 from rotating synchronously with the sanding roller 6 when installing the sanding roller 6, reducing the installation difficulty; the matching connection of thread one 505 and thread two 506 can ensure that the sanding roller 6 is firmly installed, and at the same time facilitate the disassembly and replacement of the worn sanding roller 6 later, improving work efficiency.

[0020] Specifically, such as Figure 1 and Figure 3 As shown, the adjustment assembly includes an adjustment cavity 701 inside the support platform 7. A limiting groove 702 is formed on the lower surface of the adjustment cavity 701. A bidirectional lead screw 703 is rotatably connected to the inside of the limiting groove 702 through a bearing. The side surfaces at both ends of the bidirectional lead screw 703 are provided with threads in opposite directions. The adjustment assembly also includes a pair of moving frames 704 slidably connected inside the adjustment cavity 701. The moving frames 704 are U-shaped, and the support roller 8 is rotatably connected inside the moving frames 704. The bottom of the pair of moving frames 704 is provided with a protrusion, and the pair of moving frames 704 are threadedly connected to the bidirectional lead screw 703 through the protrusion. The protrusion is adapted to the shape of the limiting groove 702. A servo motor 705 is fixedly installed on the right side of the support platform 7. The transmission end of the servo motor 705 extends into the inside of the adjustment cavity 701 and is fixedly connected to one end of the bidirectional lead screw 703.

[0021] In this invention, the adjustment component is configured such that a servo motor 705 drives a bidirectional lead screw 703 to rotate. During rotation, the bidirectional lead screw 703, through its threaded connection with the moving frame 704 and the adaptation of the protrusion to the shape of the limiting groove 702, drives a pair of moving frames 704 to move relative to each other. This achieves adjustment of the distance between a pair of support rollers 8, thereby improving the adaptability to grinding rollers 6 with different radii and facilitating the adaptation to grinding rollers 6 of different sizes, effectively improving practicality and convenience.

[0022] Specifically, such as Figure 1 and Figure 4 As shown, the processing chamber 2 has entrances and exits on the left and right sides, and an observation port is provided at the front end of the processing chamber 2. The observation port is hinged to a door 9.

[0023] During equipment operation, staff can observe the processing status of the PET belt inside the processing chamber 2 through the observation port at the front end of the processing chamber 2. When it is necessary to inspect or clean the internal components of the processing chamber 2, the door 9 can be opened around the hinge of the observation port. After the operation is completed, the door 9 can be closed to keep the processing chamber 2 in a relatively closed environment.

[0024] Specifically, such as Figure 1 As shown, a support leg 10 is fixedly connected to the bottom of the processing box 1, and an anti-slip pad 11 is fixedly connected to the bottom of the support leg 10.

[0025] The support leg 10 lifts the processing box 1 off the ground, which can prevent the bottom of the processing box 1 from getting damp and corroded due to long-term contact with the ground. At the same time, it can also prevent debris on the ground from causing wear on the bottom of the processing box 1, thus extending the service life of the processing box 1. The anti-slip pad 11 increases the friction between the support leg 10 and the ground, which can effectively prevent the equipment from sliding due to the vibration of internal components such as the conveyor roller 3 and the servo motor 705 during operation, thus ensuring the stability of the equipment during operation.

[0026] Specifically, such as Figure 2 As shown, the inner cavity of the abrasive roller 6 is filled with a heat-insulating filler, which is made of ceramic fiber or rock wool; the heat-insulating filler is in contact with the outer surface of the resistance heating rod 502.

[0027] The ceramic fiber or rock wool insulation filling material inside the frosting roller 6 has a low thermal conductivity, high temperature resistance and strong chemical stability. When it comes into contact with the outer surface of the resistance heating rod 502, it can tightly wrap the heating rod to reduce heat loss and keep the frosting roller 6 in the optimal matte processing temperature range, avoiding uneven processing of PET strip caused by temperature fluctuations. It can also reduce the energy consumption of the resistance heating rod 502 to save operating costs.

[0028] Working principle and usage process of this utility model: When operating the PET belt surface matte treatment equipment, if it is necessary to disassemble or replace the worn sanding roller 6, the machine must be stopped and the power supply disconnected first to ensure that the resistance heating rod 502 cools down to a safe temperature. Then, open the door 9 of the observation port at the front of the treatment chamber 2, start the hydraulic cylinder 4 to move the telescopic end to move the support frame 5 and the sanding roller 6 upward away from the support roller 8 to leave room for operation. Next, use a wrench to hold the hexagonal locking block 504 on the side of the connecting ring 503 to fix the connecting ring 503. Then rotate the sanding roller 6 in the opposite direction to gradually separate the second thread 506 at the opening of the inner cavity of the sanding roller 6 from the first thread 505 on the side of the connecting ring 503. After the threads are completely separated, remove the old sanding roller 6 from the side of the support base 501 and clean the impurities on the surface of the support base 501 and the outer surface of the resistance heating rod 502. When replacing the new sanding roller 6, first align the inner cavity of the new sanding roller 6 with the support base 501 and the resistance heating rod 502, so that the second thread 506 of the sanding roller 6 is aligned with the first thread 505 of the connecting ring 503, and use a wrench to clamp the hexagonal block 504 to fix the connecting ring 503. Rotate the new sanding roller 6 in the forward direction until the threads are fully tightened to ensure that the sanding roller 6 is installed firmly and without looseness. After replacement, start hydraulic cylinder 4 to adjust the position of the sanding roller 6 so that it corresponds vertically with the support roller 8. Close the box door 9 and start the equipment according to the normal procedure. Feed the PET belt into the processing chamber 2 from one side entrance and exit. Use the symmetrical conveyor rollers 3 to transport it stably. Hydraulic cylinder 4 pushes the sanding roller 6 to clamp the PET belt with the support roller 8. The support base 501 supplies power to the resistance heating rod 502 for heating. The ceramic fiber or rock wool insulation filling in the inner cavity of the sanding roller 6 reduces heat loss and gives the PET belt a matte finish. The staff monitors the processing through the observation port. The processed PET belt is sent out from the other side entrance and exit.

[0029] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
