Description

Technical Field

[0001] This invention relates to the field of packaging device technology, and more specifically, to a packaging device for fan coil units. Background Technology

[0002] A fan coil unit is one of the terminal devices in an air conditioning system, consisting of a small fan, an electric motor, and a coil (air heat exchanger). When chilled or hot water flows through the coil, it exchanges heat with the outside air, thus cooling, dehumidifying, or heating the air to regulate indoor air parameters. It is a commonly used terminal device for both cooling and heating.

[0003] In existing technologies, fan coil units are stored as inventory after production and testing, often simply covered with a disposable plastic bag before packaging, which is then discarded during unpacking and installation. There is a lack of dust protection measures between storage and shipment, and manually covering them with disposable plastic bags is inefficient. Furthermore, existing technologies, such as the Chinese utility model patent CN201922027347.6 which discloses a packaging protection device and fan coil unit, primarily improve the external box of the fan coil unit, without effectively addressing dust prevention.

[0004] Therefore, it is necessary to propose a packaging device for fan coil units to at least partially solve the problems existing in the prior art. Summary of the Invention

Both the first transverse guide plate and the second transverse guide plate have cutting grooves corresponding to the hot cutting plate.

[0012] According to an embodiment of the present invention, the encapsulation device for fan coil units includes a waste treatment component that further includes a front pressing mechanism. The front pressing mechanism includes an L-shaped seat rod with two front pressing roller sections disposed on the L-shaped seat rod. A first upper guide roller section and a second upper guide roller section are respectively disposed at both ends of the waste lifting seat. A first lower guide roller section corresponding to the first upper guide roller section and a second lower guide roller section corresponding to the second upper guide roller section are respectively disposed at both ends of the waste base.

[0013] According to an embodiment of the present invention, the packaging device for fan coil units further includes an electrostatic dust removal unit in the outer conveying section. The electrostatic dust removal unit includes an electrostatic dust removal box, and at least two electrostatic dust removal roller modules are arranged at intervals inside the electrostatic dust removal box.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0037] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0038] like Figures 1-7 As shown, the present invention provides a packaging device for fan coil units, comprising: a packaging device body 100, wherein the packaging device body 100 includes an outer conveying part 1, an outer packaging part 2, and an inner packaging part 3, wherein the outer conveying part 1, the outer packaging part 2, and the inner packaging part 3 are installed sequentially, wherein an upper plastic bag unit 11 is installed on one side of the outer conveying part 1, and a lower plastic bag unit 12 is installed on the outer conveying part 1, wherein the free ends of the upper plastic bag unit 11 and the lower plastic bag unit 12 preferably enter the outer packaging part 2.

[0039] In use, the two free ends of the two components are heat-cut by the outer packaging section 2 to form a plastic bag with one end sealed. When the fan coil unit needs to be packaged, it is placed on the outer conveying section 1, which moves it towards the outer packaging section 2. The fan coil unit then enters the outer packaging section 2 and into the sealed end of the plastic bag 200. The outer packaging section 2 continues to move the fan coil unit, causing it to drag the upper plastic bag unit 11 and the lower plastic bag unit 12. The upper and lower plastic bag units 11 and 12 then completely cover the fan coil unit. The outer packaging section 2 then seals the other end of the fan coil unit. The plastic bag unit 12 is heat-cut, forming a plastic bag 200 with the other end sealed between the upper plastic bag unit 11 and the lower plastic bag unit 12. At the same time, the outer packaging part 2 also heat-cuts both sides of the upper plastic bag unit 11 and the lower plastic bag unit 12, forming a complete plastic bag 200 between the upper plastic bag unit 11 and the lower plastic bag unit 12. Then, the plastic bag 200 wraps around the fan coil unit and enters the inner packaging part 3. After being heated by the inner packaging part 3, the plastic bag 200 shrinks onto the fan coil unit 300, thereby achieving a sealed packaging of the fan coil unit, effectively preventing dust and moisture. Moreover, this process replaces manual bagging, greatly improving work efficiency.

[0040] Exemplary outer packaging

[0041] Furthermore, some embodiments of the present invention provide a specific structure of the outer packaging part 2 described above, wherein the outer packaging part 2 has a movable heat cutting mechanism 21, which is used to heat cut the upper plastic bag unit 11 and the lower plastic bag unit 12.

[0042] Specifically, the movable heat-cutting mechanism 21 includes an inverted U-shaped frame 211, the ends of which are hinged to the outer packaging part 2. The two sides of the inverted U-shaped frame 211 are respectively mounted on the outer packaging part 2 via a cylinder rod or an electric telescopic rod 212. A heat-cutting blade 213 is installed in the middle of the inverted U-shaped frame 211. Therefore, under the action of the cylinder rod or the electric telescopic rod 212, the inverted U-shaped frame 211 can be driven to move up and down relative to the outer packaging part 2. Thus, when the free ends of the upper plastic bag unit 11 and the lower plastic bag unit 12 enter the outer packaging part 2... On the packaging section 2, the inverted U-shaped frame 211 moves from top to bottom, so that the hot cutting blade 213 heat-cuts the free ends of the upper plastic bag unit 11 and the lower plastic bag unit 12 to form one end of the plastic bag 200 and seals it. Then the inverted U-shaped frame 211 rises again. After the fan coil unit moves into place, the inverted U-shaped frame 211 moves from top to bottom again, and the hot cutting blade heat-cuts the upper plastic bag unit 11 and the lower plastic bag unit 12 again to seal the other end of the plastic bag 200. At the same time, the seal of one end of the next new plastic bag 200 is also formed.

[0043] The above structural design greatly improves the efficiency of hot cutting of the upper plastic bag unit 11 and the lower plastic bag unit 12, and the plastic bag formed by hot cutting has good sealing performance, playing a role in dust prevention, moisture prevention and other functions.

[0044] Exemplary waste treatment components

[0045] like Figures 4-5 As shown, in some embodiments of the present invention, two waste processing components 4 are further installed on the outer packaging part 2. The two waste processing components 4 are located on both sides of the movable hot cutting mechanism 21. The waste processing components 4 can perform hot cutting on both sides of the upper plastic bag unit 11 and the lower plastic bag unit 12 and remove excess waste 201, so that after the formed plastic bag 200 wraps the fan coil unit, it can be completely shrunk and formed when heated and shrunk in the inner packaging part 3. After the plastic bag 200 shrinks, it can better fit onto the fan coil unit and has an aesthetic effect.

[0046] Specifically, the aforementioned waste processing component 4 includes a waste base 41 and a waste lifting seat 42. The waste base 41 is installed on the upper side of the outer packaging part 2, and the waste lifting seat 42 is movably installed on the waste base 41 via a vertical screw slide 424. The vertical screw slide 424 has a rotating handle 425. By rotating the rotating handle 425, the vertical screw slide 424 can be driven to move the waste lifting seat 42 up and down. The waste base 41 is equipped with... A first transverse guide plate 411 is installed, and a second transverse guide plate 421 is installed on the waste material lifting seat 42. The second transverse guide plate 421 is located above the first transverse guide plate 411. When the waste material lifting seat 42 moves up and down, it also drives the second transverse guide plate 421 to move relative to the first transverse guide plate 411. This allows for adjustment of the gap between the two, facilitating the passage of the upper plastic bag unit 11 and the lower plastic bag unit 12 through the first transverse guide plate 411 and the second transverse guide plate 421.

[0047] Meanwhile, a lifting and cutting section 43 is installed on the waste material lifting seat 42. The lifting and cutting section 43 can perform hot cutting on the upper plastic bag unit 11 and the lower plastic bag unit 12 so that the upper plastic bag unit 11 and the lower plastic bag unit 12 form the side seal of the plastic bag 200.

[0048] Exemplary lifting and cutting section

[0049] Further embodiments of the present invention provide a specific structure of the above-mentioned lifting and cutting section 43. The lifting and cutting section 43 with this structure can perform hot cutting of the upper plastic bag unit 11 and the lower plastic bag unit 12. The lifting and cutting section 43 with this structure includes a cutting cylinder 431 and a cutting seat 432. The cutting cylinder 431 is installed on the waste material lifting seat 42 and is located above the second transverse guide plate 421. The cutting seat 432 is installed at the bottom of the cutting cylinder 431. A hot cutting plate 433 is installed on the cutting seat 432. A hot cutting conductor 434 is installed at the bottom of the hot cutting plate 433. The height of the hot cutting plate 433 can be adjusted by the cutting cylinder 431 so that the hot cutting plate 433 can be separated from the first transverse guide plate 411 and the second transverse guide plate 421 after cutting, which is convenient for subsequent maintenance.

[0050] The heat-cutting plate 433 cuts off the excess parts of the upper plastic bag unit 11 and the lower plastic bag unit 12 to form a plastic bag 200, while the cut-off parts on both sides are waste material 201.

[0051] Correspondingly, cutting grooves 401 are provided on the first transverse guide plate 411 and the second transverse guide plate 421, so that the hot cutting plate 433 can enter the two cutting grooves 401 downwards to perform hot cutting on the sides of the upper plastic bag unit 11 and the lower plastic bag unit 12. At the same time, after heating the sides of the upper plastic bag unit 11 and the lower plastic bag unit 12, the two can be melted and sealed together to form the side seal of the plastic bag 200.

[0052] Furthermore, a front pressing mechanism 44 is also installed on the waste processing assembly 4. The front pressing mechanism 44 includes an L-shaped seat rod 441, which is installed at the front end of the waste base 41. Two front pressing roller sections 442 are installed on the L-shaped seat rod 441. Therefore, the upper plastic bag unit 11 and the lower plastic bag unit 12 pass through the gap between the two front pressing roller sections 442 and are initially squeezed synchronously to prevent them from moving out of alignment.

[0053] Furthermore, a first upper guide roller section 422 and a second upper guide roller section 423 are respectively installed at both ends of the waste material lifting seat 42, and a first lower guide roller section 412 and a second lower guide roller section 413 are respectively installed at both ends of the waste material base 41. Correspondingly, the first upper guide roller section 422 is located above the first lower guide roller section 412, and the second upper guide roller section 423 is located above the second lower guide roller section 413. Therefore, the upper plastic bag unit 11 and the lower plastic bag unit 12 maintain a state of synchronous movement after passing through the first upper guide roller section 422, the first lower guide roller section 412, the second upper guide roller section 423, and the second lower guide roller section 413. Moreover, the waste material 101 also plays a traction role on the upper plastic bag unit 11 and the lower plastic bag unit 12 under the action of the first upper guide roller section 422, the first lower guide roller section 412, the second upper guide roller section 423, and the second lower guide roller section 413.

[0054] Furthermore, two first guide rings are installed between the first lower guide roller section 412 and the second lower guide roller section 413, and the two first guide rings slide through the two first inner guide grooves of the first transverse guide plate 411.

[0055] An auxiliary guide roller section 424 is also installed on the waste material lifting seat 42. Two second guide rings are arranged between the first upper guide roller section 422, the second upper guide roller section 423, and the auxiliary guide roller section 424. The two second guide rings slide through the two second inner guide grooves of the second transverse guide plate 421. The two first inner guide grooves are located on both sides of the cutting groove 401, and the two second guide rings are also located on both sides of the cutting groove 401. This makes the first guide rings and the second guide rings correspond to each other vertically, which can drive the waste material 201 to move outward and prevent the waste material 201 from accumulating and becoming disordered on the outer packaging part 2.

[0056] Exemplary inner packaging

[0057] like Figure 6 As shown, further, some embodiments of the present invention provide a specific structure of the inner packaging part 3 described above. This inner packaging part 3 includes a support frame 31 and a packaging box 32. The support frame 31 is located at one end of the outer packaging part 2. The packaging box 32 is mounted on the support frame 31. The packaging box 32 contains an inner conveying mechanism 33 and two heating mechanisms 34, located on the upper and lower sides of the inner conveying mechanism 33, respectively. Therefore, after the plastic bag 200 wraps around the fan coil unit and enters the packaging box 32, the inner conveying mechanism 33 drives the fan coil unit to move slowly within the packaging box 32, while the two heating mechanisms 34 are activated to heat it. This causes the plastic bag 200 to shrink after heating, thus fitting snugly around the fan coil unit, providing dust and moisture protection while also being aesthetically pleasing.

[0058] Furthermore, the aforementioned heating mechanism 34 includes heating frames 341, with two heating frames 341 located on the upper and lower sides of the inner conveying mechanism 33, respectively. Multiple heat conductors are installed within the heating frames 341. When energized, these heat conductors generate heat, thereby heating and shrinking the plastic bag 200. Multiple temperature measuring units 342 are also configured at the bottom of the heating frames 341. These units monitor the temperature inside the sealing box 32 to prevent excessively high or low temperatures, thus ensuring proper heating and maintaining the sealing function of the plastic bag 200.

[0059] Furthermore, the heating frame 341 has a quick-release assembly (not shown) for fixing the heat conductor, which facilitates the fixing and installation of the heat conductor for easy replacement later.

[0060] Exemplary electrostatic precipitator

[0061] like Figure 1 , Figure 7 As shown, in some embodiments of the present invention, an electrostatic dust removal unit 5 is further installed in the outer conveying unit 1. The electrostatic dust removal unit 5 performs electrostatic dust removal treatment on the lower plastic bag unit 12 to prevent dust from adhering to the lower plastic bag unit 12 due to static electricity. The electrostatic dust removal unit 5 of this structure includes an electrostatic dust removal box 51. At least two electrostatic dust removal roller modules 52 are installed at intervals in the electrostatic dust removal box 51. The lower plastic bag unit 12 enters the electrostatic dust removal box 51 and passes through the at least two electrostatic dust removal roller modules 52 to achieve the electrostatic dust removal effect.

[0062] Understandably, an electrostatic dust removal unit 5 can be configured for the upper plastic bag unit 11 to perform electrostatic dust removal treatment on the upper plastic bag unit 11, so as to prevent dust from entering the plastic bag 200.

[0063] Exemplary electrostatic dust removal roller module

[0064] like Figure 7 As shown, further, some embodiments of the present invention provide a specific structure of the electrostatic dust removal roller module 52 described above. The electrostatic dust removal roller module 52 of this structure includes an anti-stick dust removal roller 53, two antistatic rollers 54, and two bearing support parts 55. The two bearing support parts 55 are installed at intervals in the electrostatic dust removal box 51. The anti-stick dust removal roller 53 has a first roller shaft 531 at its end, and the antistatic roller 54 has a second roller shaft 541 at its end. The first roller shaft 531 and the second roller shaft 541 are installed through the bearing support parts 55. The bearing support parts 55 make the first roller shaft 531 and the second roller shaft 541 rotate more smoothly, and the lower plastic bag unit 12 can pass better between the anti-stick dust removal roller 53 and the two antistatic rollers 54.

[0065] In this embodiment, the electrostatic dust removal roller module 52 has an anti-stick dust removal roller 53 and two antistatic rollers 54. The lower plastic bag unit 12 enters between the two antistatic rollers 54 and exits between one of the antistatic rollers 54 and the anti-stick dust removal roller 53. In this way, the two antistatic rollers 54 can perform electrostatic treatment on the inner and outer surfaces of the lower plastic bag unit 12, while the anti-stick dust removal roller 53 performs dust removal treatment on the inner surface, so as to prevent the lower plastic bag unit 12 and the upper plastic bag unit 11 from being contaminated with dust when forming the plastic bag 200.

[0066] It is understood that this embodiment is also equipped with an electrostatic generator corresponding to the antistatic roller 54, as well as a vacuum cleaner, etc. The electrostatic generator and the vacuum cleaner are existing components well known to those skilled in the art, and the specific structural components will not be described in detail.

[0067] Exemplary bearing support

[0068] like Figure 8 , Figure 9As shown, the bearing support portion 55 further includes a support plate 56, an inverted U-shaped fastener 57, and an inner support assembly 58. The inverted U-shaped fastener 57 is mounted on the support plate 56, while the inner support assembly 58 is mounted between the support plate 56 and the inverted U-shaped fastener 57. A first bearing member 571 is installed between the top of the inner support assembly 58 and the top of the inverted U-shaped fastener 57, and a second bearing member 572 is installed between the inner support assembly 58 and the support plate 56. A first roller shaft 531 is installed inside the first bearing member 571, and a second roller shaft 541 is installed inside the second bearing member 572. The bearing 571 and the second bearing 572 facilitate the rotation of the first roller shaft 531 and the second roller shaft 541, so that the lower plastic bag unit 12 can easily pass between the anti-stick dust removal roller 53 and the anti-static roller 54. Moreover, the aforementioned inner bearing assembly 58 can fix the first bearing 571 and the second bearing 572 of different sizes in the inverted U-shaped fastener 57, and control the distance between the anti-stick dust removal roller 53 and the two anti-static rollers 54 to facilitate the passage of lower plastic bag units 12 of different thicknesses, and also make the rotation of the first bearing 571 and the second bearing 572 more stable.

[0069] Exemplary internal carrier component

[0070] like Figures 8-15 As shown, in some embodiments of the present invention, the inner bearing component 58 includes a multi-faceted bearing corner piece 59, a first support member 60, and three second support members 61. Here, the multi-faceted bearing corner piece 59 has three concave bearing surfaces 591, which can contact the outer circular surfaces of the first bearing member 571 and the second bearing member 572 to better fix them.

[0071] Specifically, the first support member 60 is disposed within the central support frame 62 of the multi-faceted bearing corner member 59, and three second support members 61 are evenly distributed on the three external protrusions 590 of the multi-faceted bearing corner member 59 and connected to the central support frame 62. Two of the second support members 61 are connected to the inverted U-shaped fasteners 57, and the remaining second support member 61 is connected to the bearing plate 56. The first support member 60 can support the first bearing member 571 and the second bearing member 572 from the inside, while the three second support members 61 also provide auxiliary support for the first bearing member 571 and the second bearing member 572. The operation and control of the three second support members 61 can control the distance between the anti-stick dust removal roller 53 and the two antistatic rollers 54. The three second support members 61 also have good detachability, which facilitates the subsequent disassembly and maintenance of the anti-stick dust removal roller 53 and the two antistatic rollers 54.

[0072] Exemplary first support member

[0073] like Figure 12As shown, the first supporting member 60 further includes a supporting cylinder 601 and three spring rods 602. The supporting cylinder 601 is installed inside the middle support frame 62. Each spring rod 602 includes a spring cylinder 603, a spring rod 604, a first spring body 605, and a first outer support plate 606. Multiple spring cylinders 603 are evenly installed on the supporting cylinder 601. The inner wall of the supporting cylinder 601 has an inner fixing plate 607 corresponding to the spring cylinder 603. The inner fixing plate 607 prevents the supporting cylinder 601 from detaching from the supporting cylinder 601. The inner end of the spring rod 604 is connected to the spring cylinder 603 through the first spring body 605. The outer end of the spring rod 604 passes through the first inner hole 621 of the middle support frame 62. The first outer support plate 606 is installed on the outer end of the spring rod 604 and is located in the outer support groove 5911 of the concave bearing surface 591. The first outer support plate 606 also has a first wear-resistant plate 608. After the first wear-resistant plate 608 contacts the first bearing member 571 (second bearing member 572), it presses the first spring body 605 inside. The first spring body 605 provides elastic support for the spring rod 604, so that the first outer support plate 606 and the first wear-resistant plate 608 can better support and fix the first bearing member 571.

[0074] Exemplary second support member

[0075] like Figures 13-14 As shown, further, some embodiments of the present invention provide a specific structure of the second support member 61. The second support member 61 of this structure includes a support moving rod 611, a support rotating cylinder 612, and two inner support rods 613. Here, the support rotating cylinder 612 is rotatably installed in the first rotating hole 571 of the inverted U-shaped fastener 57, while the support moving rod 611 is screwed into the support rotating cylinder 612. Therefore, by rotating the support rotating cylinder 612, the support moving rod 611 can reciprocate within the inverted U-shaped fastener 57 and the inner bearing assembly 58. In turn, the support moving rod 611 can drive the second support member 61 to support the first bearing member 571 and the second bearing member 572 on both sides, thereby changing the distance between the anti-stick dust removal roller 53 and the two antistatic rollers 54, and also making the rotation of the anti-stick dust removal roller 53 and the two antistatic rollers 54 more stable.

[0076] The inner end of the support moving rod 611 passes through the second inner hole 592 of the multi-faceted bearing corner piece 59 and extends into the third inner hole 593. The two inner support rods 613 are installed in the two side grooves 614 of the support moving rod 611. The inner end of the inner support rod 613 has a retaining plate 615, which can move in the side groove 614. The side groove 614 has a first fixing rod 616 corresponding to the inner support rod 613, which makes it convenient to fix the inner support rod 613 after support.

[0077] Furthermore, a second outer support plate 617 is installed on the inner support rod 613, and a second wear-resistant plate 618 is installed on the second outer support plate 617. The two second wear-resistant plates 618 on both sides can cooperate with the first wear-resistant plate 608 in the middle to support the first bearing component 571 and the second bearing component 572, and cooperate with the external inverted U-shaped fastener 57 to wrap around the first bearing component 571 and the second bearing component 572 to achieve fixation, and also make the first bearing component 571 and the second bearing component 572 rotate more smoothly.

[0078] Furthermore, since the second support member 61 can fix and support the first bearing member 571 of different sizes, an inner support groove 594 is provided on the inner wall of the multi-faceted bearing corner member 59. The inner support rod 613 passes through the inner support groove 594, and a second fixing rod 595 is installed in the inner support groove 594. The second fixing rod 595 can be in the second rotating hole 619 of the inner support rod 613. In this way, the inner support rod 613 can move in the inner bearing assembly 58 following the support moving rod 611, and then fit with the first bearing member 571 (second bearing member 572) of different sizes to achieve support and fixation.

[0079] Exemplary auxiliary internal support

[0080] like Figure 15 As shown, in some embodiments of the present invention, a plurality of auxiliary inner support members 63 are further installed inside the inverted U-shaped fastener 57. The plurality of auxiliary inner support members 63 can abut against the first bearing member 571 and the second bearing member 572. Specifically, the aforementioned auxiliary inner support member 63 includes an auxiliary C-shaped side plate 631, a side block 632, and an auxiliary side cap 633. One end of the auxiliary C-shaped side plate 631 is hinged in the auxiliary groove 572 of the inverted U-shaped fastener 57, and the auxiliary side cap 633 is fastened in the auxiliary groove 572 to fix the aforementioned auxiliary C-shaped side plate 631. A side block 632 is installed on one side of the auxiliary C-shaped side plate 631. An inner trapezoidal block 634 is installed on the side block 632. The inner trapezoidal block 634 can be hinged in the auxiliary side cap 633. The auxiliary side cap 633 has an auxiliary spring body 635 that abuts against the inner trapezoidal block 634. In this way, the auxiliary inner support 63 can always fit against the first bearing member 571 (second bearing member 572) under the action of the auxiliary spring body 635, so that the inverted U-shaped fastener 57 can better fix the first bearing member 571 (second bearing member 572).
