Description

Technical Field

[0001] The invention relates to a telescopic shield, in particular to a scale-type telescopic shield. Background Art

[0002] like Figure 1 , 2 As shown in Figure 3, there is a scale-type telescopic shield for a processing machine (such as a chip cutting machine, not shown), which includes a protective curtain 1 that can be unfolded or folded, a support module 2 connected to the protective curtain 1, and a scale module 3 for shielding the top side of the protective curtain 1. The protective curtain 1 includes a top curtain body 101, and two side curtain bodies 102 connected to both sides of the top curtain body 101. The top curtain body 101 has a plurality of ridges 103 arranged in a length direction X and extending along a transverse direction Y, and a plurality of top folding parts 104 connected between the ridges 103. When the protective curtain 1 is unfolded, each top folding part 104 can define a concave space 105. The support module 2 includes a movable plate 201 disposed at the front end of the protection curtain 1, a fixed plate 202 disposed at the rear end of the protection curtain 1, and a plurality of support ribs 203 disposed in the protection curtain 1 and fixed to the corresponding ridges 103. Figure 2 , 3 As shown in FIG. 4 , the scale module 3 includes several scales 301 of the same specification, one of the scales 301 located at the front end is fixed to the movable plate 201 , and the remaining scales 301 are connected to the corresponding ridges 103 and fixed to the tops of the corresponding supporting ribs 203 .

[0003] By this, Figure 4 , 5 As shown, when the processing machine is to perform processing operations, the movable plate 201 can be driven forward to unfold the originally folded protective curtain 1, so that the scales 301 originally overlapped are pulled apart to overlap each other front and back, and the top curtain body 101 of the protective curtain 1 is covered. At this time, the supporting ribs 203 will be spaced apart from each other to support the unfolded protective curtain 1. In this way, the mechanism (such as the lead screw, not shown) covered by the protective curtain 1 can be protected, and the scales 301 can also protect the top curtain body 101 of the protective curtain 1.

[0004] When the scale-type telescopic shield is deployed, the protective curtain 1 is closest to the tool of the processing machine at the end of the movable plate 201 and is usually the most frequently deployed place. Therefore, the first few scales 301 adjacent to the end of the movable plate 201 are also most frequently pulled open. However, since the scale-type telescopic shield is deployed in a one-to-one manner, each scale 301 is responsible for directly shielding the concave space 105 of the respective top folding portion 104. Therefore, the concave spaces 105 of the first few top folding portions 104 adjacent to the end of the movable plate 201 need to be covered by the same number of the first few scales 301. To cover it, although the first few scales 301 can cover the top of the concave space 105 of the first few top folding parts 104, a gap will still be formed between these scales 301, causing the waste of cut chips to fall onto these scales 301. It is easy to have the opportunity to fall into the concave space 105 of the first few top folding parts 104 through the gaps between these scales 301, so that the protective curtain 1 may be cut by the waste during the process of unfolding and folding, causing the cutting fluid (such as pure water) used in processing to leak into the interior of the protective curtain 1, causing the mechanism under the protective curtain 1 to rust. Summary of the invention

[0008] The support unit comprises a movable plate arranged at the front end of the protective curtain unit, and a plurality of support ribs, each of which is connected to a corresponding peak ridge portion and is located under the top curtain body.

[0009] The scale unit is used to shield the top side of the protective curtain unit, and includes an extended scale and a plurality of standard scales.

When the protective curtain unit is in the unfolded state, the extended scale directly shields the concave space of at least two of the top folding parts closest to the movable plate, and the standard scales respectively shield the concave spaces of the remaining top folding parts other than the at least two top folding parts. The standard scales are connected to the corresponding peak ridges located on both sides of the remaining top folding parts, and the standard scales are fixed to the corresponding supporting ribs, and the corresponding supporting ribs are connected to the corresponding peak ridges.

[0011] The scale-type telescopic shield of the present invention, the first shielding block of the extended scale has a first horizontal plate portion connected to the first mounting block, a first inclined plate portion extending backward and downward from the first horizontal plate portion, and a first overlapping portion extending backward and downward from the first inclined plate portion, and the second shielding block of each standard scale has a second horizontal plate portion connected to the second mounting block, and a second overlapping portion extending backward and downward from the second horizontal plate portion.

[0012] The scale-type telescopic shield of the present invention, the protective cloth curtain unit also includes two side curtain bodies, the side curtain bodies are respectively connected to the opposite sides of the top curtain body along the length direction and extend downward, each side curtain body has a plurality of side ridges arranged in the length direction and corresponding to the peak ridges, and a plurality of side folding portions corresponding to the top folding portions, each side folding portion is connected between any two adjacent side ridges, and the opposite ends of each supporting rib are connected to the side ridges corresponding to the side curtain bodies.

[0013] The scale-type telescopic shield of the present invention, the support unit also includes a fixing plate arranged at the rear end of the protective cloth curtain unit.

[0014] The beneficial effect of the present invention is that: the scale unit of the present invention utilizes the design of the extended scale in conjunction with the standard scale, and the extended scale can directly cover the concave space of the first few top folding parts closest to the movable plate in a one-to-many manner. Even if the protective curtain unit is most often unfolded at this end of the movable plate, the extended scale will only form a gap with one of the standard scales at the front end, and this gap is still located outside the concave space of the first few top folding parts. In this way, the present invention can greatly reduce the chance of waste materials that fall onto the extended scales due to cutting operations and accidentally fall into the concave space of the first few top folding parts, so that the protective curtain unit will not be easily cut by waste materials during the process of unfolding and folding, and can effectively prevent the cutting fluid (such as pure water) used during processing from leaking into the interior of the protective curtain unit, thereby avoiding rusting of the mechanism under the protective curtain unit.

[0027] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0028] See also Figure 6 , 7 8 is an embodiment of the flared telescopic shield 100 of the present invention. The flared telescopic shield 100 includes a protective curtain unit 10, a support unit 20, and a flaked unit 30. In this embodiment, the flared telescopic shield 100 can be used in a processing machine (such as a chip cutting machine, not shown).

[0029] The protective curtain unit 10 can be in an unfolded state along a length direction X (see Figure 8 , 9 ) and a folded state (see Fig.11 , 12 ) and includes a top curtain body 11 and two side curtain bodies 12. In the present embodiment, the protective cloth curtain unit 10 is formed by folding a piece of cloth.

[0030] The top curtain body 11 has a plurality of ridges 111 arranged in a length direction X and extending along a transverse direction Y, and a plurality of top folded portions 112 extending along the transverse direction Y. Each top folded portion 112 is connected between any two adjacent ridges 111 .

[0031] The side curtain bodies 12 are respectively connected to the left and right opposite sides of the top curtain body 11 along the length direction X and extend downward. Each side curtain body 12 has a plurality of side ridges 121 arranged in the length direction X and corresponding to the peak ridges 111, and a plurality of side folding portions 122 corresponding to the top folding portions 112. Each side folding portion 122 is connected between any two adjacent side ridges 121.

[0032] like Figure 8 As shown, when the protective curtain unit 10 is in the unfolded state, the peak ridges 111 are separated from each other, the top folded portions 112 are unfolded, each top folded portion 112 defines a concave space 113, the side ridges 121 are separated from each other, and the side folded portions 122 are unfolded. Fig.11As shown, when the protective curtain unit 10 is in the folded state, the peak ridges 111 are close to each other, the top folding portion 112 is folded, the side ridges 121 are close to each other, and the side folding portions 122 are folded.

[0033] like Figure 7 , 8 As shown, the support unit 20 includes a movable plate 21 disposed at the front end of the protection curtain unit 10 , a fixed plate 23 disposed at the rear end of the protection curtain unit 10 , and a plurality of support ribs 22 .

[0034] like Figure 8 , 9 As shown in FIG. 10 , the top side of each supporting rib 22 is connected to one of the corresponding peak ridges 111 , and the left and right opposite ends of each supporting rib 22 are connected to the corresponding side ridges 121 of the side curtain body 12 . The supporting ribs 22 are arranged inside the protective curtain unit 10 and are located under the top curtain body 11 .

[0035] like Figure 7 , 9 As shown in FIG. 10 , the scale unit 30 is used to shield the top side of the protective curtain unit 10 , and includes an extended scale 31 and a plurality of standard scales 32 .

[0036] In this embodiment, the extended scale 31 has a first mounting block 311 fixed to the movable plate 21, and a first shielding block 312 extending rearward from the first mounting block 311. The first shielding block 312 of the extended scale 31 has a first horizontal plate portion 313 connected to the first mounting block 311, a first inclined plate portion 314 extending rearward and downward obliquely from the first horizontal plate portion 313, and a first lap portion 315 extending rearward and downward obliquely from the first inclined plate portion 314.

[0037] In this embodiment, each standard scale 32 has a second mounting block 321 and a second shielding block 322 extending rearward from the second mounting block 321. The second shielding block 322 of each standard scale 32 has a second horizontal plate portion 323 connected to the second mounting block 321, and a second overlapping portion 324 extending rearward and downward obliquely from the second horizontal plate portion 323.

[0038] When the protective curtain unit 10 is in the unfolded state, the extended scale 31 directly covers the concave space 113 of at least two of the top folding parts 112 closest to the movable panel 21, and the standard scale 32 respectively covers the concave space 113 of the remaining top folding parts 112 outside the at least two of the top folding parts 112, and the standard scale 32 is connected to the corresponding peak ridge parts 111 located on both sides of the remaining top folding parts 112, and the standard scale 32 is fixed to the corresponding supporting rib 22, and the corresponding supporting rib 22 is connected to the corresponding peak ridge part 111.

[0039] In this embodiment, when the protective curtain unit 10 is in the unfolded state, the extended scale 31 directly covers the concave space 113 of four of the top folding portions 112 (for clear marking, additionally marked as 112Ⅰ) that are closest to the movable panel 21, and the standard scale 32 respectively covers the concave space 113 of the remaining top folding portions 112 (for clear marking, additionally marked as 112Ⅱ) other than the four top folding portions 112. It can be understood that in other variations of the present embodiment, the number of concave spaces 113 of the top folding portions 112 (112Ⅰ) directly covered by the extended scale 31 may also be two, three or more than four.

[0040] The standard scale 32 is connected to the corresponding peak ridge portion 111 (additionally marked as 111Ⅰ for clear marking) located on both sides of the remaining top folding portion 112 (112Ⅱ), and the standard scale 32 is fixed to the corresponding supporting rib 22 (additionally marked as 22Ⅰ for clear marking), and the corresponding supporting rib 22 (22Ⅰ) is connected to the corresponding peak ridge portion 111 (111Ⅰ).

[0041] like Fig. 9 , 10 As shown, when the protective curtain unit 10 is in the unfolded state, the first mounting block 311 of the extended scale 31 is away from the second mounting block 321 of one of the standard scales 32 that is most adjacent to the extended scale 31, the first overlapping portion 315 of the first shielding block 312 of the extended scale 31 is overlapped on the second horizontal plate portion 323 of the second shielding block 322 of one of the standard scales 32, the second mounting blocks 321 of any two adjacent standard scales 32 are away from each other, the rear ends of the second overlapping portions 324 of the second shielding blocks 322 of any two adjacent standard scales 32 are away from each other, and the second shielding blocks 322 of the standard scales 32 are overlapped with each other. Specifically, the second overlapping portion 324 of the second shielding block 322 of the previous standard scale 32 will overlap the second horizontal plate portion 323 of the second shielding block 322 of the next standard scale 32.

[0042] like Fig.11 , 12As shown, when the protective curtain unit 10 is in the folded state, the first mounting block 311 of the extended scale 31 is adjacent to the second mounting block 321 of one of the standard scales 32, the first shielding block 312 of the extended scale 31 is located above the second shielding block 322 of the standard scale 32, the second mounting blocks 321 of any two adjacent standard scales 32 are adjacent to each other, the rear ends of the second overlapping portions 324 of the second shielding blocks 322 of any two adjacent standard scales 32 are adjacent to each other, and the second shielding blocks 322 of the standard scales 32 overlap each other.

[0043] By this, Fig. 9 , 10 As shown, when the processing machine is to perform processing operations, the movable plate 21 can be driven forward to move the protective curtain unit 10 from the folded state (see Fig.11 , 12 ) is unfolded to the unfolded state, so that the extended scale 31 and the standard scale 32 that were originally overlapped are sequentially pulled apart to overlap each other front and back, and the top curtain body 11 of the protection curtain unit 10 is covered. At this time, the supporting ribs 22 are spaced apart from each other to support the unfolded protection curtain unit 10. In this way, the mechanism (such as the lead screw, not shown) covered by the protection curtain unit 10 can be protected, and the extended scale 31 and the standard scale 32 can also protect the top curtain body 11 of the protection curtain unit 10.

[0044] Through the above description, the advantages of the present invention can be summarized as follows:

[0045] 1. The scale unit 30 of the present invention utilizes the design of the extended scale 31 in conjunction with the standard scale 32. The extended scale 31 can directly cover the concave space 113 of the first four top folding parts 112 (112I) closest to the movable plate 21 in a one-to-many manner. Even if the protective curtain unit 10 is most often unfolded at this end of the movable plate 21, the extended scale 31 will only form a gap with one of the standard scales 32 at the front end, and the gap is still located at the first four top folding parts 112 (112I). 2Ⅰ), compared with the prior art, the present invention can greatly reduce the chance of waste materials falling onto the extended scale 31 due to cutting chips and accidentally falling into the concave space 113 of the first four top folding parts 112 (112Ⅰ), so that the protective curtain unit 10 will not be easily cut by the waste materials during the process of unfolding and folding, and can effectively prevent the cutting fluid (such as pure water) used in processing from leaking into the interior of the protective curtain unit 10, thereby avoiding rusting of the mechanism under the protective curtain unit 10.

[0046] 2. The first shielding block 312 of the extended scale 31 of the scale unit 30 of the present invention utilizes the first inclined plate portion 314 to extend obliquely backward and downward from the first horizontal plate portion 313, and cooperates with the design that the first overlapping portion 315 extends obliquely backward and downward from the first inclined plate portion 314. When the protective curtain unit 10 is in the unfolded state, the first overlapping portion 315 of the first shielding block 312 of the extended scale 31 will generate an elastic force that is constantly pressed toward one of the standard scales 32 located at the front end, so that the two are tightly overlapped together.

[0047] 3. The scale unit 30 of the present invention utilizes the extended design of the extended scale 31. When the protective curtain unit 10 is in the folded state, the extended scale 31 will cover the top of the standard scale 32 to protect the standard scale 32 and reduce the chance of foreign matter invading between the standard scales 32.

[0048] In summary, the scale-type telescopic shield of the present invention can not only effectively reduce the chance of waste materials generated during processing accidentally falling into the concave spaces of the first few top folding parts of the protective curtain unit, but also prevent the protective curtain unit from being easily cut by waste materials during the process of unfolding and folding, thereby truly achieving the purpose of the present invention.

[0049] The above are only embodiments of the present invention and should not be used to limit the scope of the present invention. That is, any simple equivalent changes and modifications made according to the claims and description of the present invention are still within the scope of the present invention.
