Description

Technical Field

[0001] The utility model belongs to the technical field of woodworking machinery, and in particular relates to an improvement of a dust cover structure used on a milling machine. Background Art

[0002] Sanding with a belt sander is a traditional method for improving the surface flatness and finish of wood panels. However, sanding processes have limited throughput, consume large amounts of sandpaper, and result in high costs. Large processing volumes are labor-intensive, time-consuming, and inefficient. Furthermore, sanding machines require high power, requiring a high-power power distribution system in processing plants. Consequently, milling machines have been developed in recent years for high-volume wood panel processing. Milling machines utilize milling techniques to process wood panels, offering high efficiency and low costs. They also consume little power and do not require a high-power power distribution system, making them easy to deploy and apply.

[0003] The milling machine has a conveyor line for conveying plates and is equipped with a milling head for milling the plates. The milling head can move up and down to perform milling operations on the plates conveyed to the conveyor line.

[0004] To prevent dust, a dust cover is provided at the corresponding cover at the position of the milling head, and a dust suction port is provided on the dust suction cover, which is connected to the dust suction pipe. The dust and waste generated by the milling head when milling the plate are sucked away by a centrifugal fan.

[0005] In order to press and position the plate during milling, a pressure roller bracket is arranged correspondingly at a position close to the rear side of the dust hood. Multiple groups of pressure rollers are arranged on the pressure roller bracket. The pressure roller bracket and the pressure rollers constitute a pressure roller assembly. The arrangement of the pressure roller assembly makes the space behind the dust hood limited.

[0006] When setting the dust suction port on the dust suction hood, in order to ensure the dust suction effect, the dust suction port should be set around the dust suction hood. However, since the space on the rear side of the dust suction hood is relatively narrow, if the dust suction port is set, a large number of dust suction pipes cannot be arranged, resulting in the dust suction port cannot be set on the side of the dust suction hood close to the pressure roller. This greatly reduces the number of dust suction ports, and since no dust suction port is set on the rear side, the dust suction amount is reduced and the dust suction effect is worsened. Utility Model Content

[0007] In view of the above technical problems existing in the prior art, the utility model provides a dust collection hood for a milling machine, which increases the dust collection amount and improves the dust collection effect through structural improvement.

[0008] In order to achieve the above-mentioned utility model / design purpose, this utility model adopts the following technical solutions:

[0009] A dust collecting hood for a milling machine, comprising:

[0010] The cover body is internally divided into a first cavity with an open bottom and a closed second cavity located on the side thereof;

[0011] A milling head passing portion is provided on the cover body, which is arranged through the cover body and communicates with the first cavity. A plurality of milling head passing portions are provided and arranged in sequence along the direction of the first side of the cover body;

[0012] The first dust suction portion is arranged on one side of the cover body corresponding to the position of the first cavity. A plurality of first dust suction portions are provided and arranged in sequence along the direction of the first side of the cover body;

[0013] The second dust suction member is arranged on the cover body on the side opposite to the first dust suction portion and extends from the first cavity to the second cavity along the direction of the first side. A dust suction cavity is formed between it and the cover body, and the dust suction cavity communicates with the first cavity and the second cavity, and is used to send the dust adsorbed from the first cavity into the second cavity;

[0014] The third dust suction portion is arranged on the cover shell and communicates with the second cavity, and is used to send out the dust from the second cavity.

[0015] Compared with the prior art, the advantages and positive effects of the present utility model are:

[0016] The dust suction cover for the milling machine proposed by the present utility model improves the structure of the dust suction cover. A second dust suction member is arranged at the cover body near the pressure roller assembly. A dust suction cavity is formed by enclosing the second dust suction member and the cover body and communicates with the first cavity. At the same time, it communicates with the second cavity located at the side through the second dust suction member. The dust debris and other substances adsorbed from the first space are circulated through the second dust suction member, enter the second cavity at the side position, and are sucked out through the third dust suction portion corresponding to the position of the second cavity.

[0017] By arranging the second dust suction member, the flow direction of the adsorbed dust debris is changed, so that the adsorbed dust debris is sucked from the first space and discharged from the third dust suction portion at the side position. In this way, there is no need to connect a dust suction pipe to the second dust suction member, but only to connect the dust suction pipe to the third dust suction portion at the side, effectively solving the problem that it is impossible to set a dust suction port due to the narrow space on the side of the cover body close to the pressure roller assembly where it is impossible to arrange a dust suction pipe.

[0018] By arranging the second dust suction member on the cover body near the pressure roller assembly, it can be used to adsorb the dust debris at the first space, increasing the number of dust suction members, increasing the number of dust suction ports, increasing the dust suction volume, and having a better dust suction effect.

[0019] In addition, during the structural arrangement, the first dust prevention member and the second dust prevention member are arranged on two opposite sides of the cover body, and the second dust suction member near the pressure roller assembly is extended to the side of the second cavity and communicates with the second cavity to discharge dust. The entire dust suction cover structure is not only compact but also occupies a small space, making it suitable for the installation requirements of small spaces.

[0034] In the description of the present utility model, unless otherwise stated, the meaning of "a plurality" is two or more.

[0035] In some embodiments of the present application, a dust suction hood for a milling machine is proposed. The milling machine mainly drives a milling head to rotate through a motor, and performs milling operations on the plates conveyed through a conveyor line to process the surfaces of the plates.

[0036] To achieve the conveyance of the plates, a conveyor line is provided below it, and a pressure roller assembly is assembled on the conveyor line for pressing and positioning the plates to facilitate the operation of the milling head.

[0037] To achieve the shielding and adsorption of the dust and debris generated during the operation of the milling head, a dust suction hood is provided at the position of the milling head, which can at least shield the dust or debris generated by the milling head of the milling machine and prevent the dust from spreading everywhere.

[0038] In some embodiments of the present application, the dust hood includes:

[0039] A hood body 100, which is internally divided to form a first cavity 110 with an open bottom and a closed second cavity 120 located at its side.

[0040] A milling head passing portion 130 is provided on the hood body 100, which is arranged through the hood body 100 and communicates with the first cavity 110. A plurality of milling head passing portions 130 are provided and arranged in sequence along the direction of the first side 141 of the hood body 100.

[0041] In some embodiments, the milling head passing portion 130 is a milling head passing hole arranged through the hood body 100 for the milling head to pass through.

[0042] The milling head for milling the plate passes through the milling head passing portion 130 and reaches the plate through the first space.

[0043] Since the milling head passing portion 130 communicates with the first space, and the milling head operates after passing through the milling head passing portion 130 and the first space, the dust and debris generated by the milling operation of the milling head on the plate are basically located at the position of the first space.

[0044] Therefore, the adsorption of dust and debris mainly focuses on the position of the first space.

[0045] A plurality of milling head passing portions 130 are provided to cooperate with a plurality of milling heads, so that the entire plate milling machine can perform milling operations simultaneously through a plurality of milling heads at one time, improving the milling efficiency of the plate.

[0046] A first dust suction portion 200 is arranged on one side of the hood body 100 corresponding to the position of the first cavity 110. A plurality of first dust suction portions 200 are provided and arranged in sequence along the direction of the first side 141 of the hood body 100.

[0047] In some embodiments of the present application, the first dust suction portion 200 is a first dust suction cylinder, which is arranged on the hood shell and at least partially extends into the first cavity 110.

[0048] In some embodiments of the present application, the first dust suction portion 200 is a first dust suction cylinder, which is arranged on the top surface of the hood body 100 at the position of the first cavity 110. A first connection port is provided on the hood body 100, and the first dust suction cylinder communicates with the first cavity 110 through the first connection port.

[0049] The first dust suction cylinder is connected to a dust suction pipe, and the dust suction pipe is communicated with the main dust discharge pipe. A centrifugal fan for adsorbing dust and debris is arranged on the main dust discharge pipe.

[0050] When the centrifugal fan is operating, substances such as dust in the first space connected to the first dust suction cylinder are adsorbed into the first dust suction cylinder through the centrifugal force of the centrifugal fan, then enter the dust suction pipe, and finally are discharged through the total dust discharge pipe.

[0051] In some embodiments, the first side 141 is the side in the length direction of the housing 100 or the side in the width direction of the housing 100.

[0052] The first dust suction part 200 is arranged in multiple numbers and arranged in sequence along the direction of the first side 141 of the housing 100, which can increase the number of dust suction members for sucking dust in the first space, increase the dust suction amount, and improve the dust suction effect.

[0053] In some embodiments of the present application, a second dust suction member 300 is further provided on the dust suction hood, which is arranged on the housing 100 on the opposite side of the first dust suction part 200 and extends from the first cavity 110 to the second cavity 120 along the direction of the first side 141.

[0054] The second dust suction member 300 is arranged opposite to the first dust suction part 200 and is respectively arranged on two opposite sides of the housing 100.

[0055] The second dust suction member 300 is closer to the pressure roller assembly on the milling machine than the first dust suction part 200.

[0056] The pressure roller assembly extends along the direction of the first side 141 of the housing 100, so that the second dust suction member 300 cannot be connected to the dust suction pipe.

[0057] A dust suction cavity is formed between the second dust suction member 300 and the housing 100, and the dust suction cavity is communicated with the first cavity 110 and the second cavity 120 for sending the dust adsorbed from the first cavity 110 into the second cavity 120.

[0058] The second dust suction member 300 is communicated with the first cavity 110 and can be used to adsorb substances such as dust debris in the first cavity 110.

[0059] The second dust suction member 300 is communicated with the second cavity 120, so that when the centrifugal fan is working, under the action of centrifugal force, the adsorbed substances such as dust debris can be sucked from the first cavity 110 to the second cavity 120.

[0060] A third dust suction part 400 is arranged at the housing corresponding to the position of the second cavity 120 and is communicated with the second cavity 120 for sending out the dust from the second cavity 120.

[0061] In some embodiments of the present application, the third dust suction part 400 is a third dust suction cylinder, which is communicated with the second cavity 120, and a dust suction pipe can be correspondingly connected to the third dust suction cylinder to discharge the dust debris in the second cavity 120.

[0062] Since the third dust suction part 400 is arranged at the side part of the housing corresponding to the position of the second cavity 120, there is sufficient space to arrange the dust suction pipe.

[0063] The dust suction hood for the milling machine proposed in this application improves the structure of the dust suction hood. A second dust suction part 300 is arranged at the hood body 100 close to the side of the pressure roller assembly. A dust suction cavity is formed by enclosing the second dust suction part 300 and the hood body 100 and is communicated with the first cavity 110. At the same time, it is communicated with the second cavity 120 located at the side through the second dust suction part 300. The substances such as dust and debris adsorbed from the first space are circulated through the second dust suction part 300, enter the second cavity 120 at the side position, and are sucked out through the third dust suction part 400 corresponding to the position of the second cavity 120.

[0064] By arranging the second dust suction part 300, the flow direction of the adsorbed dust and debris is changed, so that the adsorbed dust and debris are sucked from the first space and discharged from the third dust suction part 400 at the side position. In this way, it is not necessary to connect the dust suction pipe to the second dust suction part 300, but only to connect the dust suction pipe to the third dust suction part 400 at the side, effectively solving the problem that the dust suction port cannot be set due to the narrow space on the side of the hood body 100 close to the pressure roller assembly where the dust suction pipe cannot be arranged.

[0065] By arranging the second dust suction part 300 on the hood body 100 close to the side of the pressure roller assembly, it can be used to adsorb the dust and debris in the first space, increasing the number of dust suction parts and the number of dust suction ports, increasing the dust suction volume, and having a better dust suction effect.

[0066] In addition, during the structural arrangement, a first dust-proof part and a second dust-proof part are arranged on two opposite sides of the hood body 100, and the second dust suction part 300 close to the side of the pressure roller assembly extends to the side of the second cavity 120 and is communicated with the second cavity 120 to discharge dust. The whole dust suction hood structure is not only compact but also occupies a small space, enabling it to meet the installation requirements in small spaces.

[0067] In some embodiments of the present application, the dust suction hood further includes:

[0068] Two groups of fourth dust suction parts 500 are arranged symmetrically on both sides of the plurality of milling head passing parts 130. Each group of fourth dust suction parts 500 includes at least one fourth dust suction part 500. The fourth dust suction part 500 is arranged along the direction of the second side edge 142 of the hood body 100, corresponding to the position of the first cavity 110 and communicated with the first cavity 110, and the second side edge 142 is perpendicular to the first side edge 141.

[0069] The fourth dust suction part 500 is a fourth dust suction cylinder, which is arranged at the position of the second side 142, and adsorbs dust and debris in the first space at the position where the second side 142 is located.

[0070] Two groups of fourth milling dust components arranged on both sides of the milling head through part 130 cooperate to adsorb dust and debris from the position of the second side 142 on both sides of the first space. The first dust suction part 200 and the second dust suction part 300 are arranged along the direction of the first side 141, and can adsorb dust and debris from the position of the first side 141 on the other two sides of the first space. In this way, it can be ensured that dust suction parts are provided at all four surrounding positions of the first space, the number distribution of the dust suction parts is uniform, the dust suction amount is large and uniform, and the adsorption effect of dust and debris in the first space is ensured.

[0071] In some embodiments of the present application, an intermediate part 151 located in the middle and edge parts 152 located on both sides thereof are formed on the cover body 100.

[0072] The intermediate part 151 constitutes the middle section of the cover body 100, and the edge parts 152 constitute the edge sections of the cover body 100. There are two edge sections, which are symmetrically arranged at both ends of the middle section.

[0073] In some embodiments of the present application, the first cavity 110 is formed at the intermediate part 151, and the milling head through part 130, the first dust suction part 200 and the fourth dust suction part 500 are arranged at the intermediate part 151.

[0074] When arranging, the milling head through part 130 is arranged at the middle position of the intermediate part 151 along the length direction of the intermediate part 151.

[0075] The first dust suction part 200 is sequentially arranged at one side position of the intermediate part 151 along the length direction of the intermediate part 151;

[0076] The fourth dust suction part 500 is arranged at the other side position of the intermediate part 151 along the width direction of the intermediate part 151.

[0077] The second cavity 120 is formed at the edge part 152, and the third dust suction part 400 is arranged at the edge part 152.

[0078] Forming the first cavity 110 at the intermediate part 151 arranged at the middle position can facilitate the integrated adsorption of dust and debris at the middle position.

[0079] In some embodiments of the present application, there are two second cavities 120, which are symmetrically arranged at both ends of the cover body 100 and arranged on both sides of the first cavity 110.

[0080] To achieve the adaptive connection with the two second cavities 120, two corresponding second dust suction members 300 are provided. The two second dust suction members 300 are arranged to fit the cover body 100 and extend from the middle part 151 of the cover body 100 to the edge parts 152 at both ends of the cover body 100 respectively, so as to communicate with the two second cavities 120 at both ends of the cover body 100 respectively.

[0081] The two second dust suction members 300 communicate with the two second cavities 120 located at both ends of the cover body 100 respectively. When sucking dust, both of the two second dust suction members 300 suck dust from the first space, and then flow through to the corresponding second cavities 120 respectively, so as to discharge the dust and other substances adsorbed from the first space from the third dust suction parts 400 connected to the second cavities 120 at both side positions, achieving the effect of uniform adsorption and discharge.

[0082] In some embodiments of the present application, an installation position is formed on the side of the cover body 100, and the second dust suction member 300 is assembled to the installation position. By setting the installation position on the side of the cover body 100 to assemble the second dust suction member 300, the occupied space can be reduced.

[0083] In some embodiments of the present application, the cover body 100 includes a top member 161, side members 162 and end members 163.

[0084] The top member 161 forms the top surface of the cover body 100 and is the top plate of the cover body 100.

[0085] The side members 162 form the side surfaces of the cover body 100. There are two side members 162, which are symmetrically arranged on both sides of the cover body 100. An inclined guiding slope is formed above the side members 162, and the installation position is formed on the guiding slope.

[0086] In some embodiments, the side member 162 includes an inclined plate 1621 and a vertical plate 1622 which are connected to each other. The inclined plate 1621 is connected to the top member 161, and the vertical plate 1622 is connected to the inclined plate 1621.

[0087] When sucking dust and other substances from the first cavity 110, the inclined plate 1621 arranged obliquely can play a guiding role in the flow of dust and other substances.

[0088] The second dust-proof member is arranged at the position of the inclined plate 1621.

[0089] Correspondingly, the first dust suction part 200 is arranged at the connection position between the inclined plate 1621 and the top member 161 of the side member 162 on the other side of the cover body 100.

[0090] There are two end members 163, which are respectively connected to both ends of the two side members 162 and the top member 161.

[0091] The end member 163 is an end baffle, which is connected to both ends of the housing 100 to form a seal for both ends of the housing 100.

[0092] In some embodiments of the present application, when the dust suction shell is buckled on the cover shell, a dust suction cavity is formed between the dust suction shell and the cover shell.

[0093] One side of the dust suction shell is open, and its open side is buckled on the inclined plate 1621 of the cover shell and welded and fixed to the inclined plate 1621 to form a dust suction cavity together with the inclined plate 1621.

[0094] In some embodiments of the present application, the dust suction shell is a long dust suction box, which is arranged along the direction of the first side 141 and fits the inclined plate 1621 of the housing 100, which can reduce the occupied space.

[0095] A dust suction inlet part 1623 is provided on the cover shell at the installation position, and the dust suction inlet part 1623 communicates with the first cavity 110. The dust suction inlet part 1623 is a dust suction inlet hole, which penetrates through the inclined plate 1621.

[0096] A plurality of dust suction inlet holes are provided, and they are arranged at equal or unequal intervals along the length direction of the dust suction shell. By providing a plurality of dust suction inlets, the number of dust suction ports can be increased, the dust suction volume can be increased, and the dust suction effect can be improved.

[0097] In some embodiments of the present application, the dust suction inlet holes include a first dust suction inlet hole and a second dust suction inlet hole. The area of the first dust suction inlet hole is larger than that of the second dust suction inlet hole, and the first dust suction inlet hole is closer to the center line of the housing 100 than the second dust suction inlet hole.

[0098] The dust suction inlet hole near the middle position of the housing 100 is set to have a larger area, mainly because the amount of dust generated at the middle part 151 is the largest. The large-area dust suction inlet hole can achieve large-flow dust suction and ensure the dust suction effect.

[0099] In some embodiments, the first dust suction inlet hole and the second dust suction inlet hole are an oval dust suction hole and a circular dust suction hole respectively. The area of the oval dust suction hole is larger than that of the circular dust suction hole, and the oval dust suction hole is closer to the center line position of the housing 100 than the circular dust suction hole.

[0100] A dust suction outlet part 1624 is provided on the cover shell, and the dust suction outlet part 1624 communicates with the second cavity 120.

[0101] The dust suction outlet part 1624 is a dust suction outlet hole formed on the inclined plate 1621, which communicates with the second cavity 120 to ensure that the air flow can enter the second cavity 120.

[0102] The dust suction outlet part 1624 is arranged at the end position of the inclined plate 1621, and is arranged away from the dust suction inlet part.

[0103] In some embodiments of the present application, the dust suction hood includes:

[0104] A partition member 600, adapted to the inner contour of the hood body 100, is assembled in the hood body 100 to divide the hood body 100 into a first cavity 110 and a second open cavity 800 with an opening at the bottom.

[0105] The partition of the hood body 100 is realized through the partition member 600 to separate the first cavity 110 and the second cavity 120.

[0106] In some embodiments, the partition member 600 is a partition plate, and the partition member 600 is arranged perpendicular to the top member 161 and the side members 162 on both sides. A second open cavity 800 is formed by enclosing between the partition member 600 and the top member 161, the side members 162 and the end member 163.

[0107] In some embodiments of the present application, the dust suction hood includes: a blocking member 700, connected to the hood shell, blocking the open end to form the second cavity 120 together with the partition member 600 and the hood body 100.

[0108] The blocking member 700 is a blocking plate, and the blocking plate is arranged parallel to the top member 161. It is respectively connected to the end member 163, the side member 162 and the bottom of the partition member 600 to block the open end at the bottom of the second open cavity 800 to form a closed second cavity 120.

[0109] In some embodiments of the present application, the blocking member 700 extends from the second cavity 120 to the first cavity 110 to block the fourth dust suction port of the fourth dust suction part 500 to improve the overall aesthetics.

[0110] In some embodiments of the present application, the fourth dust suction part 500 is a fourth dust suction cylinder, and its inner diameter is larger than the inner diameter of the first dust suction cylinder.

[0111] In some embodiments of the present application, the third dust suction part 400 is a third dust suction cylinder, and at least a part of it extends into the cavity.

[0112] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, for those of ordinary skill in the art, it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions required to be protected by the present invention.
