Description

Technical Field

[0001] This utility model relates to the technical field of cutting equipment, specifically to a PVB film edge material collection device and a PVB film production line. Background Technology

[0002] Polyvinyl butyral (PVB) film is a key material widely used in the manufacture of laminated glass, including automotive windshields and building curtain walls. During the production and processing of PVB film, it is typically cut, resulting in a large amount of scrap material. This scrap material can be collected and reused, thereby reducing raw material waste during processing and lowering the production cost of PVB film.

[0003] However, in the current industry, the collection of PVB film scraps mainly relies on manual operation. Specifically, after the PVB film is cut, workers need to manually sweep and collect the scraps scattered around the processing equipment. On the one hand, the speed of manual collection is difficult to match with the rhythm of the production line, which easily leads to excessive accumulation of PVB film scraps, resulting in the need to stop production to carry out the cleaning and collection of PVB film scraps, thus reducing the production efficiency of PVB film. On the other hand, the PVB film scraps collected manually are usually piled up in a messy manner, which is not conducive to subsequent recycling and reuse.

[0004] Therefore, there is an urgent need to develop an automated edge material collection device to achieve efficient recycling of edge materials during the PVB film production process, while also addressing the technical pain points of the manual mode. Utility Model Content

[0005] This invention provides a PVB film edge material collection device, which can quickly recycle PVB film edge materials through mechanized equipment, and the recycled PVB film edge materials are neatly stored, which is conducive to their rapid use in reuse projects.

[0006] This utility model is achieved through the following technical solution:

[0007] A PVB film edge material collection device, which cooperates with a PVB film cutting device, is used to collect the PVB film edge material generated after cutting. The device includes: a drive unit comprising at least one set of edge material drive rollers, the edge material drive rollers being disposed on the side of a conveying roller in the PVB film cutting device, the conveying direction of the edge material drive rollers forming a first angle with the conveying direction of the conveying rollers; and a receiving unit for receiving the PVB film edge material output by the edge material drive rollers, wherein a receiving path for the PVB film edge material is formed between the drive unit and the receiving unit, the orientation of the receiving path conforming to the conveying direction of the edge material drive rollers.

[0008] As a further improvement of this utility model, a guide portion is provided between the driving portion and the storage portion, and the guide portion includes at least one set of guide rollers.

[0009] As a further improvement of this utility model, the guide portion also includes a tensioning structure for tensioning the PVB film edge material.

[0010] As a further improvement of this utility model, the tensioning structure includes a tensioning roller, which cooperates with the guide roller to tension the PVB film edge material.

[0011] As a further improvement of this utility model, the storage section includes an active storage roller.

[0012] As a further improvement of this utility model, the active receiving roller is provided with two sets of limiting ring blocks, and a receiving space is formed between the two sets of limiting ring blocks for receiving the PVB film edge material.

[0013] As a further improvement of this utility model, at least one of the two sets of limiting ring blocks is a movable ring block, which is fitted onto the active receiving roller by a movable mounting component.

[0014] As a further improvement of this utility model, of the two sets of limiting ring blocks, one set is a fixed ring block, which is fixed to one side of the active receiving roller; the other set is a pressure applying ring block, which is movably fitted onto the active receiving roller, and a pressure applying kit is connected to the side of the ring block away from the fixed ring block.

[0015] As a further improvement of this utility model, the pressure application kit includes a limiting block disposed on the active receiving roller on the side away from the fixed ring block, and a pressure output component connecting the limiting block and the pressure application ring block.

[0016] Secondly, this utility model provides a PVB film production line, which includes any of the above-mentioned PVB film edge material collection devices.

[0017] The beneficial effects of this utility model include:

[0018] (1) By setting the edge material drive roller in the drive unit and arranging its conveying direction, after the PVB film is cut, the main body can be transported normally to the next processing stage by the conveyor roller, while the edge material can be driven away from the main body by the edge material drive roller, thereby realizing the rapid separation of the two. At the same time, the collection unit can quickly collect the separated edge material, which on the one hand ensures that the edge material collection speed is compatible with the automated cutting speed of the PVB film, reducing the accumulation of edge material; on the other hand, it ensures that the collected edge material is placed neatly, which is conducive to rapid recycling.

[0019] (2) In the structure of this utility model, when the PVB film is cut, the remaining main body area is large, and its edge extends beyond the conveying roller and is placed on the edge material driving roller, on the one hand, the edge material driving roller still has the function of conveying the edge material away from the main body, and on the other hand, since the conveying direction of the edge material driving roller and the conveying direction of the conveying roller form a first angle, the edge material driving roller also has the function of assisting in unfolding the edge of the main body, reducing the possibility of the edge of the main body curling due to the cutting operation.

[0020] (3) In the preferred structure, one set of the two sets of limiting ring blocks is a fixed ring block, which is fixed to one side of the active collecting roller; the other set is a pressure ring block, which is movably fitted on the active collecting roller, and a pressure kit is connected to the side of the active collecting roller away from the fixed ring block. The pressure kit can force the pressure ring block to move closer to the position of the fixed ring block. In this structure, when the active collecting roller starts to collect the edge material, the pressure ring block can force the edge material to move closer to the fixed ring block for winding, which further improves the neatness of the edge material after collection.

[0027] Example 1:

[0028] This embodiment provides a PVB film edge material collection device, which is used to collect the edge material B02 generated in the PVB film cutting device. Exemplarily, in this embodiment, the PVB film cutting device includes a conveyor roller A01 and two sets of cutting blades, wherein the two sets of cutting blades respectively cut off the excess material on both sides of the PVB film, that is, edge material B02 is generated on both sides of the main body portion B01 of the PVB film.

[0029] The PVB film edge material collection device includes a drive unit 1 and a collection unit 2. The drive unit 1 includes at least one set of edge material drive rollers 101. In this embodiment, since edge material B02 is generated on both sides of the PVB film main body portion B01, therefore... Figure 1 As shown, the drive unit 1 includes two sets of edge material drive rollers 101, and the two sets of edge material drive rollers 101 are respectively arranged on both sides of the conveyor roller A01 in the PVB film cutting equipment. The conveying direction of the edge material drive rollers 101 and the conveying direction of the conveyor roller A01 form a first angle α, as shown below. Figure 1 As shown, driven by the edge material drive roller 101, the edge material B02 generated on both sides of the main body portion B01 of the PVB film gradually moves away from the main body portion B01. The receiving part 2 is used to receive the PVB film edge material B02 output by the edge material drive roller 101. In this embodiment, since two sets of edge material drive rollers 101 are provided, each has a receiving part 2 to cooperate in carrying out the collection of edge material B02 on both sides. In this embodiment, the receiving part 2 can be any device or equipment that can realize the collection of PVB film edge material, such as a receiving roller, a negative pressure adsorption receiving system, or a winding device with electrostatic adsorption.

[0030] In this structure, the separation of edge material B02 from the main body B01 and the collection of edge material B02 are both carried out by automated equipment. On the one hand, this allows the overall collection speed of edge material B02 to dynamically match the automated cutting production speed of PVB film, greatly improving the collection efficiency of edge material B02 and avoiding the accumulation of edge material B02 that would affect the processing of PVB film. On the other hand, the automated collection process also makes the collected edge material B02 more regular, which is conducive to its storage or rapid subsequent recycling.

[0031] Preferably, such as Figure 1 and Figure 3 As shown, a guide section 3 is provided between the drive section 1 and the storage section 2. In this embodiment, the guide section 3 includes a set of guide rollers 301. With this structure, during the process of the edge material B02 being transferred from the edge material drive roller 101 to the storage section 2, the guide rollers 301 can provide support and guidance for the edge material B02, avoiding a large deviation in the movement path of the edge material B02 after long-term operation, which would reduce its neatness in storage in the storage section 2.

[0032] Preferably, the guide section 3 further includes a tensioning structure 302 for tensioning the PVB film edge material B02. This structure ensures efficient storage of the PVB film in the storage section 2, and especially when using storage structures such as winding devices, it can also enhance the compactness of the wound edge material roll.

[0033] Preferably, such as Figure 1 and Figure 3 As shown, the tensioning structure 302 includes a tensioning roller 302-1, which cooperates with the guide roller 301 to tension the PVB film edge material B02. In achieving the tensioning effect, the tensioning structure 302 utilizes the guide roller 301, thereby reducing the total number of components used in the tensioning structure 302 and achieving a lightweight design.

[0034] Preferably, such as Figure 1 As shown, the storage section 2 includes an active storage roller 201, which mainly includes the storage roller body and a corresponding driving device.

[0035] Preferably, the active take-up roller 201 is provided with two sets of limiting ring blocks 201-1, and a storage space is formed between the two sets of limiting ring blocks 201-1 for storing the PVB film edge material B02. This structure avoids the edge material B02 from shifting on the active take-up roller 201 after long-term winding operations, which would otherwise lead to the dispersion and damage of the overall structure such as the edge material roll.

[0036] Preferably, in this embodiment, both sets of limiting ring blocks 201-1 are movable ring blocks, which are fitted onto the active collecting roller 201 via movable mounting parts. This allows the spacing between them, i.e., the size of the collecting space, to be adjusted according to the size of the edge material B02. In this embodiment, the movable mounting parts can be any device or assembly that can fix the movable ring blocks at any position in the axial direction of the active collecting roller 201, such as a slide rail-slider locking system or a pneumatic / hydraulic telescopic push rod system.

[0037] Example 2:

[0038] The difference between this embodiment and Embodiment 1 is that, in this embodiment, as... Figure 2 As shown, of the two sets of limiting ring blocks 201-1, one set is a fixed ring block 201-1a, which is fixed to one side of the active collecting roller 201; the other set is a pressure ring block 201-1b, which is movably fitted onto the active collecting roller 201, and a pressure kit 201-2 is connected to the side of the pressure ring block 201-1a away from the fixed ring block 201-1a. The pressure kit 201-2 can force the pressure ring block 201-1b to tend to move closer to the position of the fixed ring block 201-1a. Under this structure, when the active collecting roller 201 starts to collect the edge material B02, the pressure ring block 201-1b can force the edge material B02 to move closer to the fixed ring block 201-1a for winding, which further improves the neatness of the collected edge material B02.

[0039] Preferably, such as Figure 2 As shown, the pressure application kit 201-2 includes a limiting block 201-2a disposed on the active receiving roller 201 on the side away from the fixed ring block 201-1a, and a pressure output component 201-2b connecting the limiting block 201-2a and the pressure ring block 201-1b. The pressure output component 201-2b can be an elastic component such as a spring, or an active output force component such as a pneumatic / hydraulic telescopic push rod. In this embodiment, the pressure output component 201-2b adopts a spring structure.

[0040] Example 3:

[0041] This embodiment provides a PVB film production line, which includes a PVB film cutting device. The PVB film cutting device includes a conveyor roller A01 and two sets of cutting blades, wherein the two sets of cutting blades respectively cut off the excess material on both sides of the PVB film, resulting in edge material B02 on both sides of the main body portion B01 of the PVB film. The production line also includes a PVB film edge material collection device as described in Embodiment 1, capable of collecting the edge material B02 generated on both sides of the main body portion B01.
