2018100358 23 Mar 2018 base assembly 2 and is capable of sliding together with the sliding base assembly 2, when the eccentric locking assembly 3 is driven, the eccentric locking assembly 3 could lock the sliding base assembly 2 and the slide assembly 1 unlock the sliding base assembly 2 and the slide assembly 1;

a spacer assembly 4, which is fixed to the sliding base assembly 2 and is capable of sliding together with the sliding base assembly 2;

a material baffle 5, which is connected to the spacer assembly 4.

In the material baffle mechanism according to the present invention, the slipway assembly 1 is the only fixed assembly. Referring to Figs.5-6, the slipway assembly 1 comprises a slipway fixed to an operating platform of the woodworking band sawing machine. The slipway is formed of metal having an integrated structure. The slipway and a fixed surface of the operating platform are arranged in the horizontal plane. The slipway matching part is a matching potion which is capable of matching the slipway assembly 1 to the sliding base assembly 2. This slipway matching part is provided with a plurality of ribs, which comprise a first rib 11 and a second rib

12. The first rib 11 includes a locking surface 111 and a first abrasive surface 112. The first abrasive surface 112 is implemented as a horizontal surface and is capable of cooperating with the sliding base assembly 2 to realize a sliding process. The locking surface 111 is provided on one side of the first abrasive surface 112 and contacts with an upper end of the eccentric locking assembly 3. Meanwhile, as the eccentric locking assembly 3 is driven, the locking surface 111 could come in close contact with the upper end of the eccentric locking assembly 3, thereby, the sliding base assembly 2 and the slipway assembly 1 could lock tightly. The height of the first rib 11 is identical to the height of the second rib 12. Moreover, the sliding base assembly 2 merely contacts with the first rib 11 and the second rib 12 of the

2018100358 23 Mar 2018 slideway. The second rib 12 includes a second abrasive surface 121 and a third abrasive surface 122, wherein the second abrasive surface 121 is a horizontal plane, and the third abrasive surface 122 is a vertical plane which is perpendicular to the second abrasive surface 121. Both of the second abrasive surface 121 and the third abrasive surface 122 are capable for cooperating with the sliding base assembly 2 to realize the sliding process.

In order to install the slipway matching part onto the operating platform, the above-mentioned slipway matching part further comprises a third rib 13 and an edge portion 14. Wherein, the height of the third rib 13 is less than the height of the first rib 11 and the height of the second rib 12. The third rib 13 is connected to the second rib 12. Meanwhile, an installing groove 15 is provided between the third rib 13 and the edge portion 14. A plurality of slot holes 151 are provided on the installing groove 15. A plurality of bolts pass through the plurality of slot holes 151, then the slipway is capable of being fixed on the operating platform. Furthermore, in order to realize the accuracy of the adjustment for the material baffle, the slipway assembly 1 further comprises a scale 16, which is fixed in a rib groove 17 formed between the first rib 11 and the second rib 12, and the scale 16 is used for positioning the sliding position of the sliding base assembly 2 accurately.

Referring to Fig.7, all of the sliding base assem bly 2, the eccentric locking assembly 3, the spacer assembly 4 and the material baffle 5 are capable of sliding relative to the slipway assembly 1. In other words, all of these assemblies are slidable. Referring to Figs.8-10, the sliding base assembly 2 could be implemented as a half-surrounded structure, which has an integrated structure. This sliding base assembly 2 comprises a sliding cover board 21 and a first sliding side plate 22 and a second sliding side plate 23 located on both sides of the

2018100358 23 Mar 2018 sliding cover board 21 respectively, wherein such two sliding side plates are respectively connected to two sides of the sliding cover board 21 in a vertical manner. An upper portion of the sliding cover board 21 is capable of being fixed to the spacer assembly 4, and a lower portion of the sliding cover board 21 form a slide matching part, which is capable of cooperating with the slipway for realizing a sliding process. Wherein the slide matching part is provided with a plurality of recesses corresponding to the ribs, the plurality of recesses are capable of being engaged with the plurality of ribs. The plurality of recesses include a first recess portion 211 and a second recess portion 212 which are capable of cooperating with the first rib 11 and the second rib 12 respectively, so as to implement the sliding process. On one side of the sliding base assembly 2, the first sliding side plate 22 is provided with an axial hole 221, wherein the axial hole 221 and the eccentric locking assembly 3 are connected through the arbor 6, to implement a hinge connection between the first sliding side plate 22 and the eccentric locking assembly 3. On the other side of the sliding base assembly 2, the second sliding side plate 23 is capable of sliding within the groove between the second rib 12 and the third rib 13 constantly.

By this way, the sliding base assembly 2 merely contacts with the first rib 11 and the second rib 12 of the slipway assembly 1. In this case, a metal friction caused by a relative sliding between the sliding base assembly 2 and the slipway assembly 1 cannot be prevented. In order to reduce the sliding friction between the slipway matching part and the sliding matching part, several wear-resistant elements are proved between the slipway matching part of the slipway assembly 1 and the sliding matching part of the sliding base assembly 2. Here, these wear-resistant elements could be wear-resistant medium provided on the ribs, or could be implemented as wear-resistant pads

2018100358 23 Mar 2018 provided on the sliding matching part.

Specifically, referring to Figs.10-12, a first dovetail groove 214 and a second dovetail groove 215 are provided on the first recess portion 211 and the second recess portion 212, respectively, meanwhile, a third dovetail groove 231 is provided on the second sliding side plate 23. Here, first wear-resistant pads 24 and second wear-resistant pads 25 are installed in the first dovetail groove 214 and the second dovetail groove 215, respectively; and third wear-resistant pads 26 are located in the third dovetail groove 231. By this way, all of the direct contact between the first abrasive surface 112 and the first recess portion 211, the direct contact between the second abrasive surface 121 and the second recess portion 212, and the direct contact between the third abrasive surface 122 and the second sliding side plate 23 could be avoided.

Referring to FIG. 15, these wear-resistant pads have tapered shapes to facilitate installation. Each wear-resistant pad comprises a first pad end surface 241 embedded into the dovetail groove and a second pad end surface 242 being capable of implementing the sliding step. Here, the surface area of the first pad end surface 241 is greater than or equal to the surface area of the second pad end surface 242. Preferably, these wear-resistant pads are made of non-metallic materials, e.g., plastic pads or elastic pads. By this way, the metallic contact between the sliding base assembly 2 and the slipway assembly 1 could be avoided, and sliding damages occurred between these two assemblies could be reduced. Meanwhile, related to the slipway assembly 1 and the sliding base assembly 2, these wear-resistant pads are independent structure, thus when the wear caused by a long-time operation is serious, the smoothness could be recovered by replacing the wear-resistant pads only.

Referring to Figs.8-12, it should be noted that, for avoiding the

2018100358 23 Mar 2018 relative sliding motion between the sliding cover board 21 and spacer assembly the 4 during the sliding process, one side of the sliding cover board 21, with which the spacer assembly 4 is connected, is provided with a strip-shaped anti-skidding structure 213. Meanwhile, in order to maximize the sliding efficiency relative to the slipway assembly 1, the strip-shaped anti-skidding structure 213 extends along the extending direction of the slipway.

At the same time, the first sliding side plate 22 is provided with a plurality of screw holes 222, in which wear-resistant bolts 223 could be installed. Wherein, the wear-resistant ends of the wear-resistant bolts 233 towards the locking surface 111, which are used for avoiding a direct contact between the sliding base assembly 2 and the slipway assembly 1. Preferably, in order to reduce the production cost, the wear-resistant bolts 223 could be implemented by plastic bolts. During the process of assembling the sliding base assembly 2, the plastic bolts, whose wear-resistant ends toward the locking surface 111, pass through the screw holes 222, and thus a sliding space is capable of being formed between the sliding base assembly 2and the slipway assembly 1, so as to eliminate the direct contact between the sliding base assembly 2 and the slipway assembly 1. Therefore a nonmaterial separation forms between the sliding base assembly 2 and the slipway assembly 1.

Referring to Figs.1-4, as mentioned above, driven by the sliding base assem bly 2, the eccentric locking assem bly 3 is capable of sliding Meanwhile, the eccentric locking assembly 3 is used for locking or unlocking the sliding of the sliding base assembly 2. Preferably, the eccentric locking assembly 3 could be implemented by an eccentric handle, which is made of wear-resistant plastic, with good wear resistance and elasticity. The eccentric handle has an eccentric structure for implementing locking or unlocking process. Specifically,

2018100358 23 Mar 2018 the eccentric locking assembly 3 is connected to the first sliding side plate 22 by the arbor 6 and is capable of rotating around the arbor 6, for implementing locking process or unlocking process applied on the sliding base assembly 2. When the eccentric locking assembly 3 does not contact with the locking surface 111 of the slipway assembly 1, the sliding base assembly 2 is in an unlocking state. At this time, the sliding base assembly 2 is capable of sliding along the slipway assembly 1 together with the material baffle 5, thus the cutting size of the material could be adjusted. When the eccentric locking assembly 3 is pressed downward and the eccentric locking assembly 3 comes in close contact with the locking surface 111 of the slipway assembly 1, the sliding base assembly 2 turns into a locking state, at this time, a cutting operation could be implemented. Meanwhile, referring to Fig.13, the matching end of the eccentric locking assembly 3, which could cooperate with the locking surface 111 of the slipway assembly 1 could be a matching end having a wide area 31, thus the contact area between the eccentric locking assembly 3 and the first rib 11 could be increased, furthermore, a locking force could be improved. When the sliding base assembly 2 is locked by the eccentric locking assembly 3, a supporting force is provided by the sliding base assembly 2 for the locking process of the sliding base assembly 2, thus the deformation of the arbor 6 could be relieved. Meanwhile, the matching end 31 has a wear-resistant surface used for reducing the friction between the slipway assembly 1 and the matching end 31.

The spacer assembly 4 is provided between the sliding base assembly 2 and the material baffle 5 and is used for fixing the material baffle 5 on the sliding base assembly 2. By this way, the material baffle 5 is capable of sliding along the slipway assembly 1 together with the sliding base assembly 2. Referring to Fig.11 and Fig.14, the spacer assembly 4 includes a spacer body 41, spacer plugs 42 and a

2018100358 23 Mar 2018 locking bracket 43. Preferably, the pad body 41 forms a hollow cavity to reduce the total weight of the spacer assembly 4 and to further reduce the sliding resistance. Both the upper portion and the lower portion of the pad body 41 are provided with bolt holes, thereby fixing bolts 411 are capable passing through these bolt holes and are used for fixing the spacer body 41 to the sliding cover board 21. For improving the fastening between the fixing blot 411 and the spacer body 41, an elastic washer 412 and a flat washer 413 are further sequentially arranged at the junction of the fixing blot 411 and the spacer body 41. Furthermore, in order to avoid a rigid contact between the pad body 41 and the sliding cover board 21, a shim 7 is provided between the lower portion of the pad body 41 and the sliding cover board 21, so as to separate the pad body 41 from the sliding cover board 21. The spacer plugs 42 are plugging elements which are installed on both sides of the spacer body 41 and are used for plugging both ends of the hollow cavity of the spacer body 41. The locking bracket 43 is used for connecting the spacer body 41 and the material baffle 5. The locking bracket 43 comprises a first connecting portion and second connecting portions, where the first connecting portion is perpendicular to the second connecting portions. The first connecting portion has a strip-shaped structure and is capable of being embedded into the material baffle 5 to connect to the material baffle 5. Each second connecting portion has a cylindrical structure, these second connecting portions are capable of penetrating the spacer body 41 from its lateral side and is capable of connecting to the spacer body 41 by combined nuts 51. Wherein, the installing position between the spacer body 41 and the second connecting portion could be adjusted by the adjustment of the combined nut 51. By this way, the relative position between the material baffle 5 and the sliding base assembly 2 could be adjusted.

2018100358 23 Mar 2018

The material baffle 5 is connected to the spacer assembly 4 through the locking bracket 43. The material baffle plate 5 is provided with a T-shaped groove, and the first connecting portion of the locking bracket 43 could be embedded into this T-shaped groove. Here, it should be noted that, the connection relationship between the first connecting portion and the T-shaped groove could be implemented according to following two embodiments.. According to the first embodiment, the first connecting portion and the T-shaped groove are connected to each other in a sliding manner, i.e., the first connecting portion is capable of sliding relative to the T-shaped groove. According to the second embodiment, the first connecting portion and the T-shaped groove are connected in a fixing manner, i.e. a relative movement between the first connecting portion and the T-shaped groove is impossible. When it is necessary to adjust the distance between the material baffle 5 and the slipway assembly 1 in a direction that is perpendicular to the slipway assembly 1, the first embodiment could be implemented. At this time, the sliding base assembly 2 should be in the locking state and the material baffle 5 is pushed by it , since both of the sliding base assembly 2 and the spacer assembly 4 are locked and static, there is a relative movement occurred between the T-shaped groove of the material baffle 5 and the first connecting portion of the spacer assembly 4, until the material baffle 5 arrives at a desired position.

The operation of the material baffle mechanism includes adjusting process, locking process and unlocking process. The processes will be described hereafter.

During the adjusting process, the sliding base assembly 2, the eccentric locking assembly 3, the spacer assembly 4 and the material baffle 5 are sequentially installed above the slipway assembly 1.

2018100358 23 Mar 2018 assembly 2, the second wear-resistant pad 25 and the third wear-resistant pad 26 of the sliding base assembly 2 are connected with the first abrasive surface 112, the second abrasive surface 121 and the third abrasive surface 122, respectively. Meanwhile, by adjusting the wear-resistant bolt 223 finely, a sliding space between the abrasive surface and the locking surface 111 of the slipway assembly 1 could be formed.

During the unlocking process, the eccentric locking assembly 3 is lifted, when the eccentric locking assembly 3 does not contact with the locking surface 111 of the slipway assembly 1, the sliding base assembly 2 could be capable of sliding relative to the slipway assembly 1. At this time, the position of the material baffle 5 on the slipway assembly 1 could be adjusted according to the scale 16, to realize a fast and precise positioning.

During the locking process, the eccentric locking assembly 3 is pressed downward. When the eccentric locking assembly 3 comes in close contact with the locking surface 111 of the slipway assembly 1, the sliding base assembly 2 and the slipway assembly 1 are locking. At the moment, both the spacer assembly 4 and the material baffle 5 are in a locking state to perform a cutting process for the materials.

Referring to Fig.16, the present invention also provides a woodworking band sawing machine, which comprises the material baffle mechanism mentioned above. During the operation of the band sawing machine, the material baffle mechanism is capable of being mounted on the operating platform 8. When the band saw machine stands idle, the sliding assembly is capable of being hung on the body of the band sawing machine 9, as shown in FI G. 17, to save the space occupied by the operating platform.
