This will be described in detail below.

[0096] The base 1 has a processing area 11 and two support frames 12. The two support frames 12 are arranged on two sides of the processing area 11 and extend upward by a predetermined length. The base 1 can be a steel frame structure for carrying other components.

[0097] The first roller 2 is disposed on the top of the processing area 11 of the base 1 , and is used to drive the workpiece 201 to move after contacting the workpiece 201 .

[0098] The motor 3 is disposed on the base 1 and connected to the first roller 2 to drive the first roller 2 to roll. The motor 3 can adopt various structures that are convenient for driving the first roller 2. For example, a gear 21, a gear 31 and a chain 32 can be respectively disposed on the ends of the first roller 2 and the motor 3 corresponding to each other, so that the motor 3 can drive the chain 32, and then the chain 32 drives the first roller 2 to roll.

[0099] Figure 3 It is a front view of the present invention, Figure 3 The artifacts are hidden for illustration purposes. Figure 3 As shown, the second roller 4 is straddled between the two support frames 12 and is located above the first roller 2 , with a first predetermined spacing distance D1 between the second roller 4 and the first roller 2 , for cooperating with the first roller 2 to apply the protective film 51 to the top surface of the workpiece.

[0100] Figure 4 It is a right side view of the present invention. Figure 4 Some components such as the base are hidden in the figure for the convenience of explanation. Figures 3 to 5 As shown, the film reel 5 is arranged between the two support frames 12 and is located above the second roller 4. A protective film 51 is rolled up on the film reel 5, and the protective film 51 is wound from the front of the second roller 4 to the bottom of the second roller 4. When the workpiece 201 passes between the first roller 2 and the second roller 4 from the front, the protective film 51 is attached to the top surface of the workpiece 201, which can facilitate the protective film 51 to be attached to the workpiece 201. In addition, the main structure of the workpiece 201 can be a floor unit 202 of an elevated floor. The protective film 51 is mainly used to protect the top surface of the floor unit 202 of the elevated floor, so as to prevent dirt from remaining on the floor unit 202 of the elevated floor when performing works such as installing the floor unit 202 of the elevated floor, thereby saving cleaning costs. There are many types of elevated floor unit 202. Some elevated floor unit 202 has small protrusions such as four-side legs at the bottom, which cannot stably move on the front work table. Therefore, the workpiece 201 can be composed of an elevated floor unit 202 and a trough 203. The top center of the trough 203 has a groove 2031, and the upper edge of the groove 2031 of the trough 203 is provided with a plurality of flat plates 2032. The elevated floor unit 202 is clamped in the groove 2031 of the trough 203, which can facilitate the assembly of the elevated floor unit and the trough. Figure 5 As shown, the floor unit 202 of the elevated floor may further include: a four-sided frame 2021, a plurality of ribs and other structures (not shown); and a top plate 2022, which is arranged on the top of the four-sided frame 2021, the top surface of the top plate 2022 is a flat structure, and the four sides protrude by a predetermined length than the four-sided frame 2021, the four-sided frame 2021 is arranged in the groove 2031, and the top plate 2022 is protruded on the flat plate 2032. In addition, the trough body 203 may be made of, for example, wood, aluminum alloy or other materials.

[0101] Figure 6 Schematic diagram of the top of the front workbench and the rear workbench of the present invention being lower than the top of the first roller. Figure 6 A virtual thin chain line L1 is used to connect the top of the front workbench and the top of the rear workbench to facilitate comparison with the first roller. Figure 1 and Figure 6 As shown, the front workpiece platform 6 is disposed at the front side of the base 1 , and a plurality of front support rollers 61 are disposed on the top of the front workpiece platform 6 , wherein the top 611 of the front support roller 61 is lower than the top 22 of the first roller 2 .

[0102] The rear workpiece platform 7 is disposed at the rear side of the base 1 . A plurality of rear support rollers 71 are disposed on the top of the rear workpiece platform 7 . The tops 711 of the rear support rollers 71 are lower than the tops 22 of the first rollers 2 .

[0103] Figures 7-10 FIG. 1 is a schematic diagram of applying a protective film on a workpiece according to the present invention. Figure 7 As shown, the protective film 51 is firstly made to go around from the front of the second roller 4 to the bottom of the second roller 4, and then a first force F1 is applied manually or in other ways, and the force F1 can keep the protective film 51 against the bottom of the second roller 4. In addition, the motor 3 is started to keep the first roller 2 in a continuous rolling state. Then, the workpiece 201 is placed on the front workpiece table 6, and then a second force F2 is applied to push the workpiece 201 between the first roller 2 and the second roller 4.

[0104] like Figure 8 As shown, when the workpiece 201 enters between the first roller 2 and the second roller 4, the workpiece 201 can be driven by the first roller 2, and the second force F2 can be removed at this time.

[0105] like Fig. 9 As shown, when a portion of the workpiece 201 passes through between the first roller 2 and the second roller 4 and the protective film 51 is attached to a portion of the top surface of the floor unit 202 of the elevated floor of the workpiece 201, the first force F1 can be removed.

[0106] like Fig.10As shown, after the workpiece 201 completely passes through the first roller 2 and the second roller 4, the workpiece 201 is separated from the first roller 2 and stops moving, and at this time, the work of attaching the protective film 51 to the top surface of the floor unit 202 of the elevated floor of the workpiece 201 is completed. By using the first roller 2 as the main power to drive the workpiece 201, the workpiece 201 can stop moving after it is separated from the first roller 2, thereby achieving the following effects: 1. There will be no problem of excessive pulling out of the protective film 51, so there is no need to rush to place subsequent workpieces continuously; 2. There is no need to stop the first roller 2, and subsequent operations can be prepared conveniently; 3. The workpiece 201 passing between the first roller 2 and the second roller 4 can be used as a means to maintain the protective film 51, and the aforementioned first force F1 does not need to be applied when processing each workpiece.

[0107] Figures 11-12 This is a schematic diagram of the present invention of continuously applying protective films on multiple workpieces. In this specification, the use of "first workpiece", "second workpiece", "third workpiece" and other descriptions is only for the convenience of distinguishing different workpieces, and should not be used to limit the meaning of this case. That is, all kinds of modified designs based on the listed patent application scope should be included in the patent scope of this case. Fig.11 As shown, after the aforementioned Figures 7 to 9 After the operation, a portion of the first workpiece 201 has passed between the first roller 2 and the second roller 4. At this time, the second workpiece 201a can be placed on the front workpiece table 6, and then a third force F3 is used to push the second workpiece 201a against the back of the first workpiece 201. Fig.12 This is a schematic diagram of placing a third workpiece when a protective film is continuously applied to multiple workpieces according to the present invention, wherein descriptions such as removing the third force and applying other forces are not repeated. Fig.12 As shown, when the first workpiece 201 completely passes between the first roller 2 and the second roller 4, the second workpiece 201a is driven by the first roller 2 to move and push the first workpiece 201 to continue moving. At this time, the third workpiece 201b can be put down, and after the protective film between the first workpiece 201 and the second workpiece 201a is cut out, the first workpiece 201 is taken away. By repeating the above operation, the purpose of continuously applying protective films on multiple workpieces can be achieved quickly and stably.

[0108] like Fig.13As shown, the first roller 2 and the second roller 4 may have a predetermined elasticity, so that they are deformed (not shown) when contacting the workpiece 201, thereby increasing the contact area with the workpiece. In addition, the first predetermined spacing distance D1 between the first roller 2 and the second roller 4 may be smaller than the thickness T1 of the workpiece, so when the workpiece 201 passes between the first roller 2 and the second roller 4, the first roller 2 and the second roller 4 will increase the contact area with the workpiece 201 due to deformation; with this structure, the friction between the first roller 2 and the workpiece 201 can be used to drive the workpiece 201 to move, and the second roller 4 can be used to cover the protective film 51 on the top surface of the workpiece 201.

[0109] like Figure 2 and Fig.14 As shown, a limiting device 8 may be provided on the front workpiece table 6. The limiting device 8 further includes: a fixed bracket 81, which is provided on the front workpiece table 6 and protrudes upward from the front supporting roller 61; and a limiting platform 82, which is provided on the fixed bracket 81; and a plurality of limiting rods 83, which are arranged from front to back and provided on the limiting platform 82; and a plurality of limiting bearings 84, which are respectively provided on the plurality of limiting rods 83; by means of this structure, when the workpiece 201 is placed on the front workpiece table 6, one side of the workpiece 201 can be placed against the plurality of limiting bearings 84, and the workpiece 201 can be moved along the limiting bearings 84, so as to ensure that the workpiece 201 can be aligned with the position of the protective film 51. In addition, there is a second predetermined spacing distance D2 between the bottom 821 of the limiting platform 82 and the top of the front supporting roller 61, so as to pass over the groove 203 of the workpiece 201.

[0110] Figures 15-16 This is the second embodiment of the present invention. Figures 15-16 As shown, the base 1c is provided with an auxiliary structure 9c, and the auxiliary structure 9c further includes: two pneumatic cylinders 91c, respectively provided on the two support frames 12c, and located between the second roller 4c and the film reel 5c, and the two pneumatic cylinders 91c respectively have a telescopic rod 92c facing forward; and a driven roller 93c, spanning between the telescopic rods 92c of the two pneumatic cylinders 91c, so that the protective film 51c has a predetermined tension and can be evenly attached to the top surface of the workpiece 201c. In addition, when the telescopic rods 92c of the two pneumatic cylinders 91c extend forward, the driven roller 93c pushes the protective film 51c, so that the protective film 51c on the film reel 5c extends to a predetermined length. With this structure, the protective film 51c on the film reel 5c can be extended to a predetermined length, reducing possible interference when pulling the protective film 51c from the film reel 5c, and further ensuring that the protective film 51c can be smoothly attached to the top surface of the workpiece 201c without wrinkles.

[0111] In addition, the auxiliary structure 9c may further include a gas rod switch 94c; the gas rod switch 94c is arranged at a predetermined position on the rear workpiece platform 7c, is connected to the two pneumatic cylinders 91c, and has a sensor. When the sensor senses the workpiece 201c, it transmits a signal to control the telescopic rod 92c of the two pneumatic cylinders 91c to extend forward, which can conveniently control the timing of the driven roller 93c to push the protective film 51c.

[0112] like Figures 17 to 19 As shown, according to different use conditions, the time point when the protective film 51c on the film reel 5c needs to be extended to a predetermined length may also be different. For example, the protective film 51c on the film reel 5c may be extended to a predetermined length after a portion of the workpiece 201c has passed through between the first roller 2c and the second roller 4c or is about to completely pass through between the first roller 2c and the second roller 4c. An example is given below. Fig.17 As shown, before the workpiece 201c enters between the first roller 2c and the second roller 4c, the telescopic rod 92c of the pneumatic cylinder 91c has not yet been extended. Fig.18 As shown, after a portion of the workpiece 201c has passed between the first roller 2c and the second roller 4c and triggered the gas rod switch 94c, the telescopic rod 92c extends forward, causing the driven roller 93c to push the protective film 51c, so that the protective film 51c on the film reel 5c extends to a predetermined length. Fig.19 As shown, the workpiece 201c continues to move after the gas rod switch 94c is triggered, so that the protective film 51c covers the top surface of the workpiece 201c and the telescopic rod 92c retracts backward.

[0113] Figures 20-24 This is the third embodiment of the present invention. Figures 20-24 As shown, a lifting structure 10d may be provided between the two support frames 12d and the second roller 4d, and the lifting structure 10d further includes: two spiral lifts 101d, which are provided on the two support frames 12d; and two first connecting rods 102d, which are respectively connected to the two spiral lifts 101d and can spirally rise or spirally descend along the two spiral lifts 101d, and the bottoms of the two first connecting rods 102d are connected to the two ends of the second roller 4d; and a second connecting rod 103d, which is spanned between the two spiral lifts 101d. The forward or reverse rotation of the second connecting rod 103d can drive the two first connecting rods 102d to spirally rise or spirally descend through the two spiral lifts 101d, thereby driving the second roller 4d to rise or fall. With this structure, the first predetermined spacing D1 between the first roller 2d and the second roller 4d can be conveniently adjusted to correspond to workpieces of different thicknesses, thereby achieving the effect of conveniently applying protective films to workpieces of different thicknesses. In addition, a rotating wheel 104d can be provided at one end of the second connecting rod 103d to facilitate the rotation of the second connecting rod 103d. Fig.23This is a schematic diagram of the protective shell that hides the spiral lift. Figures 21 to 24 As shown, the two-screw elevator 101d can adopt a worm gear structure to match other components to save costs. The two-screw elevator 101d can include: a worm wheel 1011d, arranged at the top of the first connecting rod 102d; and a worm 1012d, arranged at one end of the second connecting rod 103d; and a protective shell 1013d, covering the outside of the worm wheel 1011d and the worm 1012d. The user can drive the second connecting rod 103d and the worm 1012d to rotate by rotating the wheel 104d forward or reversely, and the worm 1012d drives the worm wheel 1011d and the first connecting rod 102d to rotate, so that the second roller 4d rises or falls, thereby saving costs.

[0114] Fig.25 This is the fourth embodiment of the present invention. Fig.25 As shown, an auxiliary film reel 52e may be further provided on the two support frames 12e. The auxiliary film reel 52e is arranged between the two support frames 12e, and an auxiliary protective film 53e is rolled up on the auxiliary film reel 52e; the auxiliary protective film 53e and the protective mold 51e may be attached to the top surface of the workpiece 201e together.
