Description

Technical Field

[0001] This utility model relates to the field of adhesive film production technology, and in particular to a roll adhesive film transfer rack. Background Technology

[0002] Photovoltaic encapsulation films are an important encapsulation material for solar cell modules, used as top and bottom covers to protect the cells inside the module. Depending on their structure, photovoltaic encapsulation films are classified into EVA films, POE films, EPE films, etc.

[0003] Currently, all photovoltaic encapsulation film manufacturers use wooden pallets and cardboard boxes for packaging. During the production process, dedicated personnel are required to handle pallets, cardboard boxes, pallets and other components. This not only results in high packaging costs and a large amount of manpower, but also involves many packaging steps.

[0004] Currently, transfer racks are commonly used for transporting film rolls. Common film transfer racks have complex structures, and due to structural fit issues, the side mounting frames always have a significant amount of sway, posing a risk of collision during transport. Furthermore, when unloading, the side mounting frames need to be opened to their maximum angle and placed on the ground; when folding them up, personnel must walk to both sides to lift the mounting frames, making it inconvenient for loading / unloading film and folding the transfer rack. Utility Model Content

[0005] One objective of this invention is to overcome the shortcomings of existing technologies and provide a roll-shaped adhesive film transfer rack. To solve the aforementioned technical problems, this invention adopts the following technical solution:

[0006] A roll film transfer rack, comprising:

[0007] The base frame is equipped with a base, which includes two fixed plates that are spaced apart from each other.

[0008] Two end frames are arranged at opposite ends of the bottom frame. The two end frames can be in an upright position relative to the bottom frame to support the film roll. Each end frame includes a support column. The bottom end of the support column is rotatably connected to two fixing plates of the corresponding base, so that the end frame can rotate inward relative to the bottom frame to fold onto the bottom frame or can rotate outward relative to the bottom frame.

[0009] The limiting structure is set between the support column and the two corresponding fixed plates. The limiting structure has a limiting state and a releasing state. In the limiting state, the limiting structure can keep the end frame in an upright position relative to the bottom frame. In the releasing state, the end frame can rotate inward or outward relative to the bottom frame.

[0010] The abutment structure is installed on the base. When the limiting structure is in the released state, the abutment structure can abut against the support column to keep the end frame extended outward at a predetermined angle, wherein the predetermined angle is an acute angle.

[0011] In one embodiment, the limiting structure includes a first limiting component and a second limiting component, which act on opposite sides of the support column. The first limiting component restricts the support column from rotating outward relative to the two corresponding fixed plates, and the second limiting component restricts the support column from rotating inward relative to the two corresponding fixed plates.

[0012] The abutment structure is provided corresponding to the first limiting component so as to abut against the outer surface of the support column when the first limiting component releases its restriction on the support column.

[0013] In one embodiment, the first limiting component includes a limiting shaft and two limiting grooves, the limiting shaft being movably connected to two fixed plates, and the two limiting grooves being respectively disposed on the two fixed plates;

[0014] In the limiting state, the two ends of the limiting shaft are respectively locked in the two limiting grooves to prevent the support column from rotating outward relative to the two fixed plates. In the releasing state, the limiting shaft disengages from the two limiting grooves so that the support column can rotate outward relative to the two fixed plates.

[0015] In one embodiment, the first limiting component includes a connecting shaft and two connecting plates. The two ends of the connecting shaft are rotatably connected to the two fixed plates, and the two connecting plates are fixedly connected to the two ends of the connecting shaft. Each of the two connecting plates has a connecting hole, and the two ends of the limiting shaft pass through the two connecting holes. The connecting holes are elongated holes.

[0016] In one embodiment, the connecting shaft is configured to abut against the support column to keep the end frame extended outward by a predetermined angle, and the connecting shaft is able to abut against the outer side of the support column when the support column rotates outward by a predetermined angle.

[0017] In one embodiment, the first limiting component includes an elastic element connected between the connecting shaft and the limiting shaft, the elastic element being used to provide an elastic force to the limiting shaft to bring it closer to the connecting shaft.

[0018] In one embodiment, each limiting groove is inclined relative to the vertical direction so that the limiting shaft can be offset inward when it is engaged along the limiting groove.

[0019] In one embodiment, the second limiting component includes a first limiting block and a second limiting block. The first limiting block is disposed on the side wall opposite to the support column and the two corresponding fixed plates, and the second limiting block is disposed on the fixed plate corresponding to the first limiting block.

[0020] In the limiting state, the first limiting block and the second limiting block abut against each other to prevent the support column from rotating inward relative to the two fixed plates. In the releasing state, the first limiting block and the second limiting block are at different vertical heights and are misaligned so that the support column can rotate inward relative to the two fixed plates.

[0021] In one embodiment, each fixed plate is provided with a connecting through hole, and the bottom end of the support column is provided with a through hole corresponding to the connecting through hole. A pin is used to pass through the connecting through hole and the through hole to make the support column rotatably connected to the two fixed plates. The connecting through hole is an elongated hole extending in the vertical direction.

[0022] In one embodiment, a bottom plate is provided at the top of the bottom frame, and baffles are respectively provided on opposite sides of the top of the bottom frame, each baffle corresponding to one end frame and located on the same side of the bottom frame; and / or,

[0023] The two end frames are respectively provided with positioning grooves for inserting the roll of film.

[0024] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects:

[0025] In this invention, a roll-shaped adhesive film transfer rack includes a base frame, two end frames, a limiting structure, and a supporting structure. The base frame has a base plate, which includes two fixed plates spaced apart from each other. Each end frame includes a support column, the bottom end of which is rotatably connected to the two fixed plates of the corresponding base. Through the rotatable connection between the support column and the two fixed plates, the two end frames can rotate outward relative to the base frame to unload the adhesive film roll onto the base frame, thus facilitating unloading and feeding. Alternatively, the two end frames can also fold inward relative to the base frame to stack on top of it, thereby achieving foldable storage of the transfer rack and improving its ease of use.

[0026] Furthermore, the limiting structure keeps the end frame upright relative to the bottom frame, reducing end frame sway and ensuring stable support of the film roll, thus improving the stability of the transfer rack's support for the film roll. The abutment structure keeps the end frame extended outward at a predetermined angle, where this predetermined angle is an acute angle. Because the end frame only needs to extend at a small angle, rapid unloading of the film roll is possible, while also facilitating quick operation of the end frame by workers.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0041] Please see Figure 1 and Figure 2 As shown, the roll film transfer rack according to an embodiment of the present invention includes a bottom frame 100 and two end frames 200, as well as a limiting structure 300 and a supporting structure 400. The bottom frame 100 is provided with a base 110, and each end frame 200 includes a support column 210 for rotatably connecting to the base 110.

[0042] like Figure 3 As shown, the base frame 100 can be a generally square frame structure. The base frame 100 may include four bottom beams connected end to end, and a plurality of crossbeams connecting opposite bottom beams. Exemplarily, the top of the base frame 100 may be provided with a base plate 120, which can better support the adhesive film roll.

[0043] See Figure 3 The base frame 100 has four corners, each of which is provided with a base 110. Each base 110 includes two fixing plates 111 arranged at relatively intervals. The upper part of each fixing plate 111 protrudes upward from the upper surface of the base frame 100 to rotatably connect to the bottom end of the support column 210. The lower part of each fixing plate 111 is used to fix it to the base frame 100.

[0044] like Figure 1 As shown, two end frames 200 are disposed at opposite ends of the base frame 100. Each end frame 200 may include two support columns 210, and the two support columns 210 of each end frame 200 are rotatably connected to the bases 110 at the two corners of the base frame 100, so that the two end frames 200 can be in an upright position relative to the base frame 100 to support the film roll. Alternatively, as Figure 5 As shown, the two end frames 200 can rotate inward relative to the bottom frame 100 to fold onto the bottom frame 100. Alternatively, as... Figure 6 As shown, the two end frames 200 can rotate outward relative to the bottom frame 100 so that the film roll can be unloaded onto the bottom frame 100.

[0045] In other embodiments, the base frame 100 may also have a circular or elliptical shape, and multiple bases 110 may be arranged at intervals along the circumferential edge of the base frame 100.

[0046] See Figure 2 and Figure 4 In one embodiment of this utility model, the support column 210 is rotatably connected to the two fixing plates 111 of the corresponding base 110 by means of: each fixing plate 111 having a connecting through hole 112, and the bottom end of the support column 210 having a through hole 211 corresponding to the connecting through hole 112. A pin 500 is used to pass through the connecting through hole 112 and the through hole 211 to rotatably connect the support column 210 to the two fixing plates 111. The connecting through hole 112 is an elongated hole extending vertically.

[0047] like Figure 1 and Figure 2 As shown, when the support column 210 is in an upright position relative to the base 110, the bottom end of the support column 210 can be inserted into the base 110 at a position lower than the upper surface of the bottom frame 100. At this time, the pin 500 can be located at the bottom end of the connecting through hole 112. In addition, the limiting structure 300 limits the support column 210, which allows the end frame 200 to remain in an upright position relative to the bottom frame 100.

[0048] like Figure 5 As shown, when the end frame 200 needs to be folded inward, the end frame 200 is lifted upward so that the bottom end of the support column 210 extends upward beyond the upper surface of the bottom frame 100. At this time, the pin 500 can be located at the top of the connecting through hole 112. Then, the limiting structure 300 is released from its limiting effect on the support column 210, allowing the end frame 200 to rotate inward relative to the bottom frame 100 and fold onto the bottom frame 100.

[0049] See Figure 1 In some embodiments, the two end frames 200 are respectively provided with positioning grooves 221 for inserting the roll of film. For example, each end frame 200 also includes a support beam 220 that is laterally connected between the two support columns 210, the support beam 220 is provided with a support seat, and the positioning groove 221 is disposed on the top of the support seat.

[0050] The positioning groove 221 can be an arc-shaped groove. The number of positioning grooves 221 provided on each end frame 200 can be one, two, or even more, depending on the situation. The positioning grooves 221 on the two end frames 200 are provided one-to-one to support the two ends of the roller on which the film roll is placed.

[0051] See Figure 1 In some embodiments, baffles 130 are provided on opposite sides of the top of the bottom frame 100. Each baffle 130 corresponds to one end frame 200 and is located on the same side of the bottom frame 100. By providing baffles 130, the mechanical strength of the bottom frame 100 can be enhanced, and the parts placed on the bottom frame 100 can be protected.

[0052] See Figure 1 In some embodiments, each base 110 may have a stacking bottom corner 113 at its bottom end, and each support column 210 may have a stacking top cap 212 corresponding to the stacking bottom corner 113 at its top end. The size of the stacking top cap 212 is slightly smaller than the size of the stacking bottom foot 113, so that the stacking bottom foot 113 can be stacked on the stacking top cap 212. By setting the stacking bottom corner 113 and the stacking top cap 212, it is convenient to stack multiple transfer racks, reduce the floor space occupied, and facilitate the storage and handling of the transfer racks.

[0053] See Figure 1 In some embodiments, the bottom of the base frame 100 may be provided with two forklift frames 140, which are respectively located on opposite sides of the base frame 100. Each forklift frame 140 is provided with forklift holes for the forks of a forklift to enter. By providing forklift frames 140, the forklift can lift and transfer the transfer rack, improving the transfer stability of the transfer rack and preventing tipping during transfer.

[0054] See Figure 1 and Figure 2 As shown, in this utility model, the limiting structure 300 is disposed between the support column 210 and the two corresponding fixing plates 111. The limiting structure 300 mainly restricts the support column 210 from rotating inward and outward relative to the base 110, so that the end frame 200 remains in an upright position relative to the bottom frame 100, ensuring that the end frame 200 can stably support the film roll and effectively reduce the amount of shaking of the end frame 200.

[0055] like Figure 1 As shown, the limiting structure 300 has a limiting state and a releasing state. In the limiting state, the limiting structure 300 can keep the end frame 200 in an upright position relative to the bottom frame 100. At this time, the two end frames 200 can be used to stably support the film roll.

[0056] When the limiting structure 300 is in the released state, the end frame 200 can rotate inward or outward relative to the bottom frame 100. At this time, as... Figure 6 As shown, if a film roll is supported on both end frames 200, both end frames 200 can rotate outward simultaneously to unload the film roll onto the bottom frame 100, thereby achieving unloading of the film roll. Alternatively, as... Figure 5 As shown, if the two end frames 200 are in an idle state, the two end frames 200 can be rotated inward simultaneously to fold onto the bottom frame 100, thereby facilitating the storage and handling of the transfer rack.

[0057] See Figure 1In one embodiment, the limiting structure 300 includes a first limiting component 310 and a second limiting component 320. The first limiting component 310 and the second limiting component 320 act on opposite sides of the support column 210, respectively. The first limiting component 310 restricts the support column 210 from rotating outward relative to the two corresponding fixed plates 111, and the second limiting component 320 restricts the support column 210 from rotating inward relative to the two corresponding fixed plates 111. In this embodiment, by setting the first limiting component 310 and the second limiting component 320, the rotation of the support column 210 can be restricted from both the inner and outer sides, so that the support column 210 can be kept in an upright position relative to the base 110, thereby ensuring that the end frame 200 can stably support the film roll.

[0058] like Figure 2 As shown, in one embodiment, the first limiting component 310 can be structured as follows: the first limiting component 310 includes a limiting shaft 311 and two limiting grooves 312. The limiting shaft 311 is movably connected to two fixed plates 111, and the two limiting grooves 312 are respectively disposed on the two fixed plates 111. In the limiting state, both ends of the limiting shaft 311 are respectively engaged in the two limiting grooves 312 to prevent the support column 210 from rotating outward relative to the two fixed plates 111. In the releasing state, the limiting shaft 311 disengages from the two limiting grooves 312 so that the support column 210 can rotate outward relative to the two fixed plates 111.

[0059] See Figure 2 The connection method between the limiting shaft 311 and the two fixed plates 111 can be as follows: The first limiting assembly 310 includes a connecting shaft 313 and two connecting plates 314. The two ends of the connecting shaft 313 are rotatably connected to the two fixed plates 111, and the two connecting plates 314 are fixedly connected to the two ends of the connecting shaft 313. Each of the two connecting plates 314 has a connecting hole 315, and the two ends of the limiting shaft 311 pass through the two connecting holes 315.

[0060] The connecting hole 315 is an elongated hole to allow the limiting shaft 311 to move up and down to engage with or disengage from the limiting groove 312.

[0061] In this embodiment, the limiting shaft 311 can be rotatably connected to two fixed plates 111 through the connecting plate 314 and the connecting shaft 313. The limiting shaft 311 can quickly switch between the limiting state and the releasing state, thereby making the structure of the first limiting component 310 simple and easy to operate.

[0062] It is understood that in other embodiments, the limiting shaft 311 may also have one end rotatably connected to the corresponding fixed plate 111, and the other end being a free end. In the limiting state, the limiting shaft 311 is rotated so that it engages with the two limiting grooves 312; in the releasing state, the limiting shaft 311 is rotated so that it disengages from the two limiting grooves 312. Alternatively, the limiting shaft 311 may be set independently of the base 110. When limiting is needed, the limiting shaft 311 is engaged with the two limiting grooves 312; when limiting is not needed, the limiting shaft 311 is removed. The specific configuration can be determined according to actual needs.

[0063] See Figure 2 and Figure 3 In one embodiment, each limiting groove 312 is inclined relative to the vertical direction so that the limiting shaft 311 can be offset inward when it is engaged along the limiting groove 312. Specifically, the limiting groove 312 is an elongated groove that is inclined inward along the vertically downward direction. Therefore, when the limiting shaft 311 moves downward along the limiting groove 312, the limiting shaft 311 can gradually offset inward and gradually apply an inward force to the support column 210. In addition, the limiting effect of the second limiting component 320 on the support column 210 can restrict the relative displacement of the support column 210 in the horizontal direction from both the inside and outside, thereby effectively eliminating the gap between the support column 210 and the base 110 and reducing the amount of shaking of the end frame 200.

[0064] See Figure 2 In one embodiment, the first limiting component 310 includes an elastic element 316 connected between the connecting shaft 313 and the limiting shaft 311. The elastic element 316 provides an elastic force to the limiting shaft 311 to bring it closer to the connecting shaft 313. The elastic element 316 may be a tension spring, with its two ends fixedly connected to the connecting shaft 313 and the limiting shaft 311, respectively.

[0065] When it is necessary to limit the support column 210, the limiting shaft 311 is pulled and engaged in the limiting groove 312. At this time, the tension spring is stretched and deformed, accumulating elastic force. When the limiting shaft 311 slides along the limiting groove 312 to the bottom of the limiting groove 312, the tension spring gradually releases the accumulated elastic force, which keeps the limiting shaft 311 engaged in the bottom of the limiting groove 312. This effectively prevents the limiting shaft 311 from easily coming out of the limiting groove 312 due to bumps during transportation.

[0066] It should be noted that the elastic element 316 may be omitted in other embodiments. Furthermore, to prevent the limiting shaft 311 from dislodging from the limiting groove 312 during transportation, a limiting plate can be provided on the outer surface of the support column 210. When the limiting shaft 311 is engaged at the bottom of the limiting groove 312, the limiting plate can abut against the top of the limiting shaft 311 and prevent the limiting shaft 311 from moving upward. It is understood that the elastic element 316 and the limiting plate can also be used in combination, depending on the specific circumstances.

[0067] like Figure 2 As shown, in one embodiment, the structure of the second limiting component 320 can be as follows: the second limiting component 320 includes a first limiting block 321 and a second limiting block 322. The first limiting block 321 is disposed on the side wall opposite to the support column 210 and the two corresponding fixing plates 111, and the second limiting block 322 is disposed on the fixing plate 111 corresponding to the first limiting block 321.

[0068] In the limiting state, the first limiting block 321 and the second limiting block 322 abut against each other to prevent the support column 210 from rotating inward relative to the two fixed plates 111. In the released state, the first limiting block 321 and the second limiting block 322 are at different vertical heights and are misaligned to allow the support column 210 to rotate inward relative to the two fixed plates 111.

[0069] In this embodiment, the mutual abutment of the first limiting block 321 and the second limiting block 322 can restrict the inward rotation of the end frame 200. In conjunction with the aforementioned first limiting component 310, the rotation of the support column 210 can be restricted from both the inside and outside, so that the support column 210 can be kept in an upright position relative to the base 110, thereby ensuring that the end frame 200 can stably support the film roll.

[0070] See Figure 1 As shown, in this utility model, the abutment structure 400 is disposed on the base 110. When the limiting structure 300 is in the released state, the abutment structure 400 can abut against the support column 210 to keep the end frame 200 extended outward at a predetermined angle, wherein the predetermined angle is an acute angle.

[0071] Specifically, such as Figure 2 and Figure 6 As shown, when it is necessary to unload the film roll, the limiting shaft 311 can be disengaged from the limiting groove 312 to release the restriction on the outward rotation of the support column 210. At this time, the end frame 200 can tilt outward. When the end frame 200 tilts outward at a certain angle, the abutting structure 400 abuts against the support column 210 and prevents the support column 210 from continuing to rotate outward, that is, the end frame 200 cannot continue to tilt outward. Thus, by setting the abutting structure 400, the end frame 200 can be prevented from opening further after opening to a small angle, which facilitates the operation of the end frame 200 by workers and makes it easier for workers to load and unload film rolls and fold the transfer rack.

[0072] See Figure 1 In some embodiments, the abutment structure 400 may be provided corresponding to the first limiting component 310. That is, the abutment structure 400 may act on the outer surface of the support column 210. Specifically, the abutment structure 400 may abut against the outer surface of the support column 210 when the first limiting component 310 releases its restriction on the support column 210, so that the end frame 200 remains extended outward at a predetermined angle.

[0073] Furthermore, such as Figure 2 As shown, the connecting shaft 313 in the first limiting assembly 310 constitutes a supporting structure 400 that abuts against the support column 210 to keep the end frame 200 extended outward by a predetermined angle. Specifically, the connecting shaft 313 can abut against the outer surface of the support column 210 when the support column 210 rotates outward by a predetermined angle.

[0074] In this embodiment, the abutment structure 400 is the connecting shaft 313 in the first limiting component 310. That is, the connecting shaft 313 can not only rotate and connect the limiting shaft 311, but also abut against the outer side of the support column 210 to make the support column 210 rotate outward by a predetermined angle. This avoids the need to set other abutment structures 400 on the base 110, greatly simplifies the structure of the base 110, and thus helps to simplify the manufacturing process of the transfer rack and reduce the manufacturing cost of the transfer rack.

[0075] It is understood that in other embodiments, the abutment structure 400 may also have other structural forms. For example, the abutment structure 400 may be two abutment blocks disposed on two fixed plates 111, as long as they can abut against the outer surface of the support column 210 when the first limiting component 310 releases the restriction on the support column 210, so that the end frame 200 maintains the purpose of extending outward at a predetermined angle. The specific configuration can be made according to actual needs.

[0076] When using the roll-shaped adhesive film transfer rack of this utility model embodiment:

[0077] See Figure 1 When the film roll needs to be placed, each end frame 200 is erected so that the bottom end of each support column 210 is inserted into the lower part of the corresponding base 110. At the same time, the first limiting block 321 and the second limiting block 322 abut against each other, and then the limiting shaft 311 is inserted into the bottom of the limiting groove 312. This ensures that each end frame 200 can maintain an upright position relative to the base frame 100, and at this time, the two end frames 200 can stably support the film roll.

[0078] See Figure 6When the film roll needs to be unloaded, the limiting shaft 311 disengages from the limiting groove 312 to release the restriction on the outward rotation of the support column 210. At this time, each end frame 200 can tilt outward. When each end frame 200 tilts outward at a certain angle, the outer side of the support column 210 abuts against the connecting shaft 313. At the same time, since the bottom end of the support column 210 and the two fixing plates 111 are connected by the pin 500, the end frame 200 can remain in its current position and stop tilting outward. At this time, since both end frames 200 have tilted outward at a predetermined angle, both ends of the film roll will disengage from the positioning groove 221 and fall onto the bottom frame 100, thereby achieving rapid unloading of the film roll.

[0079] See Figure 5 When the end frame 200 needs to be folded, the end frame 200 is lifted upward so that the bottom end of the support column 210 is higher than the upper surface of the bottom frame 100. At the same time, the first limiting block 321 and the second limiting block 322 are misaligned with each other, so that the support column 210 can rotate inward relative to the bottom frame 100 and fold onto the bottom frame 100.

[0080] This utility model's roll-shaped adhesive film transfer rack, through the rotatable connection between the support column and two fixed plates, allows the two end frames to rotate outward relative to the bottom frame, enabling the adhesive film roll to be unloaded onto the bottom frame, thus facilitating unloading and feeding of the adhesive film roll. Alternatively, the two end frames can also fold inward relative to the bottom frame to stack on top of the bottom frame, thereby achieving foldable storage of the transfer rack and improving its ease of use.

[0081] The roll-shaped adhesive film transfer rack of this utility model uses a limiting structure to keep the end frame in an upright position relative to the base frame, ensuring that the end frame can stably support the adhesive film roll. Furthermore, the limiting structure includes a first limiting component and a second limiting component. Through the cooperation of the first and second limiting components, the rotation of the support column relative to the base can be restricted from both the inner and outer sides, ensuring that the support column remains in an upright position relative to the base. This effectively eliminates the gap between the support column and the base, reduces the amount of end frame sway, and improves the stability of the adhesive film roll support.

[0082] The roll-shaped adhesive film transfer rack of this utility model uses a supporting structure to keep the end frame extended outward at a predetermined angle, wherein the predetermined angle is an acute angle. Since the end frame only needs to be extended at a small angle, the film roll can be quickly unloaded and loaded, and the end frame can be easily operated by workers.

[0083] The above embodiments are merely illustrative examples of structures. The structures in each embodiment are not fixed combinations. In the absence of structural conflicts, the structures in multiple embodiments can be arbitrarily combined and used.

[0084] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
