Description

Technical Field

[0001] This utility model relates to the field of vacuum metallization machine technology, and in particular to a cooling device for PET vacuum metallized film after metallization. Background Technology

[0002] After the existing vacuum metallizing machine finishes winding the PET film, it needs to be disassembled and replaced with a new winding drum. However, due to the limited space inside the cabinet, the staff needs to enter the cabinet to disassemble and replace the PET film winding drum, which makes the disassembly process inconvenient.

[0003] A search revealed that prior art CN219156967U discloses a vacuum metallizing machine for PET film, comprising a base, cabinet, sealed door, power cord, unwinding roller, guide roller, cooling roller, take-up roller, machine body, controller, feed pipe, spraying head, vacuum pump, connecting pipe, and pushing device. This invention features a pushing device. Rotating the sealed door opens the machine, and the controller starts the motor. The motor output shaft rotates, causing the drive gear to rotate. This rotation of the drive wheel causes the crossbar to slide, which in turn moves the support plate, pushing the push plate. This pushes the take-up drum connected to the take-up roller, causing the take-up drum to move along the surface of the take-up roller and disengage from it. The take-up drum then falls onto the support frame surface, remaining inside the cabinet. This design allows for easy removal and replacement of the take-up drum when needed.

[0004] The above-mentioned equipment uses a cooling roller to cool the aluminum film after plating and a scraping mechanism is set at the bottom to remove impurities from the surface of the cooling roller. However, in the working structure of the cooling roller, the impurities will fall directly and disperse at the bottom of the machine body after removal, which makes subsequent manual cleaning very inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide a cooling device for PET vacuum metallized film after coating, which aims to solve the problem that in the working structure of the cooling roller of existing processing equipment, impurities will fall directly and disperse at the bottom of the machine body after removal, making subsequent manual cleaning very inconvenient.

[0006] To achieve the above objectives, this utility model provides a cooling device for PET vacuum metallized film after coating, including a cooling roller and a receiving assembly; The receiving assembly includes a material box, a connecting seat, an upper sliding plate, a lower sliding plate, a locking block, a positioning block, a connecting piece, a limiting pin, and a scraping component. The material box is located below the cooling roller. The connecting seat is detachably connected to the material box and is symmetrically arranged. T-shaped guide ends are vertically symmetrically arranged on the connecting seat. The T-shaped grooves on the upper sliding plate and the lower sliding plate are slidably engaged with the T-shaped guide ends on the connecting seat and are respectively fixed to the body of the processing equipment. The bottom of the locking block is mounted on the front side of one of the connecting seats via a pin. The positioning block is mounted on the upper sliding plate near the locking block and is slidably connected to the locking block. The connecting piece is used to connect the positioning block and the locking block. The limiting pin is threadedly connected to the upper sliding plate and the lower sliding plate and abuts against the rear end face of the connecting seat. The scraping component is located below the cooling roller.

[0007] The material box is equipped with a pull frame welded to its front side.

[0008] The scraping component includes a mounting block and a cleaning brush body. The mounting block is detachably connected to the body of the processing equipment. The cleaning brush body is mounted on the front side of the mounting block and can slide and scrape on the surface of the cooling roller.

[0009] The mounting block and the cleaning brush body are symmetrically arranged.

[0010] The receiving assembly further includes rolling balls, which are respectively disposed on the upper slide plate and the lower slide plate and make rolling contact with the connecting seat.

[0011] This utility model discloses a PET vacuum metallized film post-coating cooling device. During processing, the cooling roller can perform post-coating cooling of the aluminum film, while the scraping component can remove impurities from the surface of the cooling roller. The removed impurities fall directly into the material box below the cooling roller for centralized collection, thus avoiding the impurities from being scattered in various areas inside the machine body. Centralized collection also facilitates subsequent rapid processing of impurities. By removing the connecting piece and rotating the locking block, the top of the device is disengaged from the positioning block, and then the material box can be pulled forward directly to remove it. Subsequently, the centrally collected impurities can be directly dumped. This solves the problem in the existing processing equipment where, after the impurities are removed, they fall directly and disperse at the bottom of the machine body, making subsequent manual cleaning very inconvenient.

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Example 1: like Figures 1 to 3 As shown, where Figure 1 This is a schematic diagram of the overall structure of the cooling device after vacuum metallization of PET film. Figure 2 This is a structural diagram of the material bin 102. Figure 3 This is a schematic diagram of the limiting pin 109. This utility model provides a cooling device for PET vacuum metallized film after coating: it includes a cooling roller 101 and a receiving assembly. The receiving assembly includes a material box 102, a connecting seat 103, an upper sliding plate 104, a lower sliding plate 105, a locking block 106, a positioning block 107, a connecting piece 108, a limiting pin 109, and a scraping component. The scraping component includes an mounting block 111 and a cleaning brush body 112. This solution solves the problem in existing processing equipment where impurities in the cooling roller 101 fall directly and disperse at the bottom of the machine body after cleaning, making subsequent manual cleaning very inconvenient. It is understood that the aforementioned solution facilitates the centralized collection of cleaning impurities on the surface of the cooling roller 101, making subsequent cleaning easier.

[0021] In this embodiment, the cooling roller 101 can be directly adopted from the cooling roller disclosed in the prior art CN219156967U, which is used in conjunction with the processing equipment as prior art and will not be described in detail here.

[0022] The material box 102 is located below the cooling roller 101. The connecting seat 103 is detachably connected to the material box 102 and is symmetrically arranged. T-shaped guide ends are vertically symmetrically arranged on the connecting seat 103. The T-shaped grooves on the upper slide plate 104 and the lower slide plate 105 are respectively slidably engaged with the T-shaped guide ends on the connecting seat 103 and are respectively fixed on the body of the processing equipment. The bottom of the locking block 106 is installed on the front side of one of the connecting seats 103 by a pin. The positioning block 107 is installed on the upper slide plate 104 near the locking block 106 and is slidably connected to the locking block 106. The connecting member 108 is used to connect the positioning block 107 and the locking block 106. The limiting pin 109 is threadedly connected to the upper slide plate 104 and the lower slide plate 105 respectively and abuts against the rear end face of the connecting seat 103. The scraping member is located below the cooling roller 101. The receiving box 102 is bolted to both sides with connecting seats 103. The bolts are countersunk from the inside to the outside. The connecting seats 103 are vertically symmetrically provided with T-shaped guide ends for sliding engagement with the upper slide plate 104 and the lower slide plate 105, respectively. The upper slide plate 104 and the lower slide plate 105 are L-shaped, and their tails are bolted to the body of the equipment. One of the connecting seats 103 has symmetrically provided perforated limiting plates on its front side. The bottom of the locking block 106 slides between the limiting plates and then passes through the pin. The pin can be provided with retaining spring grooves on both sides. A retaining ring (not shown in the figure) is installed to prevent it from falling off and to ensure that the locking block 106 rotates smoothly vertically. The positioning block 107 is fixed by a countersunk bolt from bottom to top and is provided with a rectangular slot. The rectangular slot facilitates the sliding insertion of the top of the locking block 106. The positioning block 107 is provided with a through hole that cooperates with the through hole at the top of the locking block 106. The connecting member 108 adopts a T-shaped screw and nut. After installation, the limiting pin 109 is used to abut and limit the rear side of the connecting seat 103. The scraping component is used to assist in cleaning impurities on the surface of the cooling roller 101.

[0023] Secondly, a pull frame 110 is welded to the front side of the material box 102. This structure facilitates the installation or removal of the material box 102.

[0024] Then, the mounting block 111 is detached and connected to the body of the processing equipment; the cleaning brush 112 is installed on the front side of the mounting block 111 and can slide and scrape on the surface of the cooling roller 101. The mounting block 111 is bolted to the body of the processing equipment, and the cleaning brush 112 can be fixed by bolts. The cleaning brush 112 can directly adopt the scraping block structure under the cooling roller of the prior art CN219156967U to achieve cleaning.

[0025] Finally, the mounting block 111 and the cleaning brush body 112 are symmetrically arranged. This structure helps to improve the cleaning effect.

[0026] In addressing the problem in the existing processing equipment's cooling roller 101 working structure where impurities, after removal, fall directly and disperse at the bottom of the machine body, making subsequent manual cleaning extremely inconvenient, this invention solves the issue of impurities falling directly and dispersed at the bottom of the machine body after being removed from the existing cooling roller 101 working structure, making subsequent manual cleaning extremely inconvenient. During processing, the cooling roller 101 can undergo aluminum film plating followed by cooling, while the scraping component removes impurities from the surface of the cooling roller 101. The removed impurities fall directly into the material box 102 below the cooling roller 101 for centralized collection, thus preventing impurities from dispersing throughout the machine body. Centralized collection also facilitates rapid impurity processing. By removing the connecting piece 108 and rotating the locking block 106, its top is disengaged from the positioning block 107, and the material box 102 can be pulled forward and removed. The collected impurities can then be directly dumped, thus solving the problem in the existing processing equipment's cooling roller 101 working structure where impurities fall directly and disperse at the bottom of the machine body after removal, making subsequent manual cleaning extremely inconvenient.

[0027] Example 2: like Figure 4 and Figure 5 As shown, where Figure 4 This is a schematic diagram of the overall structure of the cooling device after vacuum metallization of PET film. Figure 5 yes Figure 4 The enlarged view at point A shows that, based on the first embodiment, this utility model provides a PET vacuum metallized film cooling device after coating. The receiving assembly further includes a rolling ball 201, which is respectively disposed on the upper sliding plate 104 and the lower sliding plate 105 and makes rolling contact with the connecting seat 103.

[0028] In this embodiment, by arranging a plurality of rollable balls 201 at intervals on the upper slide plate 104 and the lower slide plate 105 respectively, the rolling balls 201 form a rolling contact support structure when the connecting seat 103 is slidably installed, increasing the number of support points after the connecting seat 103 is installed and improving the stability of the connecting seat 103 after installation.
