Description

Technical Field

[0001] The present invention relates to the technical field of furniture manufacturing, and more particularly to a band saw machine for manufacturing intelligent classroom furniture. Background Art

[0002] The application of intelligent manufacturing in the furniture industry is developing rapidly. The most widely used is the Internet of Things (IoT) and smart home interconnection. Smart home technology allows furniture to be connected to the Internet, such as smart tables and smart beds. It can collect data through sensors and adjust the functions and settings of furniture, thereby improving the user experience.

[0003] A large number of furniture (tables, chairs, podiums, etc.) are needed in smart classrooms. These furniture need to be manufactured using wooden boards. After the boards are processed by cutting, grinding, splicing, gluing, etc., they are integrated to obtain the prototype of a smart home.

[0004] A band saw is a device used when cutting furniture to cut boards into suitable sizes for subsequent assembly. However, a band saw usually produces some wood chips and fine wood dust when sawing wooden boards. These waste chips will accumulate at the sawing position. If they are not cleaned up in time, when the board moves, the waste chips will enter the band saw along the sawing gap, causing the internal wear of the band saw to increase and the operation to be poor. The existing band saws have not yet been able to make corresponding improvements to this drawback. Summary of the invention

[0005] The present invention provides a band saw machine for manufacturing smart classroom furniture, which solves the technical problem in the related art that it is difficult to prevent chips from entering the inside of the band saw machine, thereby causing increased wear inside the band saw machine and poor operation.

[0010] As a further solution of the present invention: the air outlet regulating member comprises: a lower roller and an upper roller rotatably mounted on the wind box; a wind shielding belt wound between the lower roller and the upper roller; a front air outlet opened on the wind shielding belt; and a rear air outlet opened on the wind shielding belt;

[0011] The front air outlet and the rear air outlet are arranged in parallel along the air flow direction.

[0012] As a further solution of the present invention: the air outlet adjustment member further comprises: a slide rail symmetrically mounted on the wind shielding belt, and a baffle slidably mounted in the slide rail;

[0013] The sliding movement of the baffle relative to the slide rail can be locked.

[0014] As a further solution of the present invention: a hand wheel is fixedly sleeved on one end of the upper roller extending out of the bellows.

[0015] As a further solution of the present invention: the chip blowing mechanism further comprises: a side air outlet pipe connected to one side of the wind box; and a ring sleeve sleeved on one end of the side air outlet pipe;

[0016] The ring sleeve is rotatably connected to the bellows;

[0017] The side air outlet pipe is L-shaped, and the outlet side of the side air outlet pipe is aligned with the side of the saw blade away from the air outlet regulating member.

[0018] As a further solution of the present invention: the driving member includes: a motor; a driving wheel fixedly matched with the output end of the motor; and a transmission belt wound between the driving wheel and the lower rotating wheel.

[0019] As a further solution of the present invention: the contact surface of the transmission belt and the saw blade relative to the lower rotating wheel is parallel and staggered.

[0020] As a further solution of the present invention: a stabilizer is installed on the base, and the stabilizer includes a plurality of rotatable rollers, and the rollers are respectively in compression contact with the front side and the back side of the saw blade.

[0021] As a further solution of the present invention: the loading platform comprises: a fixed seat; a movable seat that can rotate and slide relative to the fixed seat; an arc groove provided on the movable seat; a rod body fixedly mounted on the fixed seat; and a tightening knob matched on the rod body;

[0022] The bellows is fixedly connected to the movable seat.

[0023] As a further solution of the present invention: an external thread is provided on one end of the rod body passing through the arc groove, and an internal thread is provided in the tightening knob, and the external thread cooperates with the internal thread.

[0024] The beneficial effects of the present invention are:

[0025] The present invention adopts the blowing effect to remove waste chips, preventing them from accumulating on the surface of the board and then entering the transmission structure of the band saw (i.e., the lower wheel and the upper wheel). Specifically, the air supplied by the blower is transmitted to the bellows through the duct, and finally sent out from the air outlet part of the air outlet regulating part to blow the waste chips generated by sawing away from the surface of the board.

[0026] By rotating the lower roller or the upper roller, the position of the front air outlet and the rear air outlet relative to the air slot (in the height direction) is changed, so that the rear air outlet and the front air outlet are aligned with the waste chip accumulation surface, thereby adapting to the change in the position of the waste chip accumulation surface when sawing plates of different thicknesses.

[0027] The baffle is moved relative to the slide rail and locked in real time. Existing locking methods such as bolts and magnetic suction can be used here, which will not be elaborated here. After the baffle is moved, the height of the exposed part of the front air outlet changes immediately, which can adapt to the different heights of waste chips accumulated when sawing boards of different materials.

[0028] The wind force of the bellows is divided, with one part used for blowing away the deposits around the saw blade and on the side of the saw blade facing the air outlet, and the other part directly guided to the side of the saw blade away from the air outlet adjustment member through the side air outlet pipe. The two parts are combined so that when sawing, all chips near the contact surface of the saw blade and the plate can be affected by the blowing, further improving the chip removal effect and preventing chips from entering the inside of the band saw machine along the sawing gap.

DETAILED DESCRIPTION

[0039] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that the discussion of these implementations is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Various examples may omit, replace, or add various processes or components as needed. In addition, the features described in some examples may also be combined in other examples.

[0040] like Figure 1-Figure 8 As shown, a band saw machine for manufacturing intelligent classroom furniture includes a base 10; a driving member 20 mounted on the base 10; a lower rotating wheel 30 and an upper rotating wheel 40 rotatably mounted on the base 10; a saw blade 50 wound in a band shape and matched between the lower rotating wheel 30 and the upper rotating wheel 40; a loading platform 70 mounted on the base 10; and a chip blowing mechanism 80 matched between the base 10 and the loading platform 70;

[0041] The output end of the driving member 20 cooperates with the lower rotating wheel 30 to drive the lower rotating wheel 30 to rotate;

[0042] The chip blowing mechanism 80 includes: a blower 801; a conduit 802 connected to the air outlet of the blower 801; a bellows 803 installed on the loading platform 70, one side of the bellows 803 is connected to the conduit 802, and the other side is provided with a wind slot 804; and a wind outlet adjustment member 805 matched with the wind slot 804;

[0043] The air outlet adjusting member 805 is provided with an air outlet portion which can be adjusted up and down relative to the air slot 804, and the opening size of the air outlet portion is adjustable.

[0044] In view of the current situation that if the waste chips of the band saw machine are not cleaned in time during use, adverse effects will be caused, the present invention makes the following specific improvements:

[0045] First, the waste chips are removed by blowing to prevent them from accumulating on the surface of the board and then entering the transmission structure of the band saw (i.e., the lower wheel 30 and the upper wheel 40). Specifically, the blower 801 sends air to the bellows 803 through the duct 802, and finally sends it out from the air outlet of the air outlet regulating member 805 to blow the waste chips generated by sawing away from the surface of the board;

[0046] However, in actual operation, due to the different thicknesses of the plates, the heights of the waste accumulation surfaces are also different. In order to ensure that the formed blowing action surface is highly aligned with the waste accumulation surface and to ensure an excellent cleaning effect, the present invention makes the following arrangements:

[0047] The air outlet adjustment member 805 includes: a lower roller 8051 and an upper roller 8052 rotatably mounted on the air box 803; a wind shielding belt 8053 wound between the lower roller 8051 and the upper roller 8052; a front air outlet 8054 opened on the wind shielding belt 8053; and a rear air outlet 8055 opened on the wind shielding belt 8053;

[0048] The front air outlet 8054 and the rear air outlet 8055 are arranged parallel to the air flow direction.

[0049] By rotating the lower roller 8051 or the upper roller 8052, the positions of the front air outlet 8054 and the rear air outlet 8055 relative to the wind slot 804 (in the height direction) are changed, so that the rear air outlet 8055 and the front air outlet 8054 are aligned with the waste accumulation surface, thereby adapting to the change in the position of the waste accumulation surface when sawing plates of different thicknesses.

[0050] When sawing a plate, the height of the waste chips generated in real time will be different due to the different plate materials. Specifically, when sawing a hard plate, the waste chips generated in real time have a large specific gravity and the waste chips have a low stacking height. When sawing a soft plate, the waste chips generated in real time have a small specific gravity and the waste chips have a high stacking height. The above-mentioned fixed-size air outlet (i.e., the front air outlet 8054) is still lacking for such a situation. Therefore, the present invention further improves as follows:

[0051] The air outlet adjustment member 805 further includes: a slide rail 8056 symmetrically mounted on the wind shielding belt 8053, and a baffle 8057 slidably mounted in the slide rail 8056;

[0052] The sliding movement of the baffle 8057 relative to the slide rail 8056 can be locked.

[0053] The baffle 8057 is moved relative to the slide rail 8056 and locked in real time. Existing locking methods such as bolts and magnetic attraction can be used here, which will not be elaborated here. After the baffle 8057 is moved, the height of the exposed part of the front air outlet 8054 changes immediately, which can adapt to the different heights of waste chips accumulated when sawing boards of different materials.

[0054] Further research has found that the above-mentioned blowing and clearing means can only cover the deposits on the side of the saw blade 50 and the side of the saw blade 50 facing the air outlet, while the chips are generated near the contact surface of the saw blade 50 and the plate. Considering that the saw blade 50 itself has a certain volume, the chips on the back side of the saw blade 50 cannot be affected by the above-mentioned blowing because they are blocked by the saw blade 50. Therefore, the present invention is further configured as follows:

[0055] The chip blowing mechanism 80 further includes: a side air outlet pipe 806 connected to one side of the wind box 803; and a ring sleeve 807 sleeved on one end of the side air outlet pipe 806;

[0056] The ring sleeve 807 is rotatably connected to the bellows 803;

[0057] The side air outlet duct 806 is L-shaped, and the outlet side of the side air outlet duct 806 is aligned with the side of the saw blade 50 that is away from the air outlet adjustment member 805 .

[0058] The wind force of the bellows 803 is divided, with one part used for blowing away the deposits on the side of the saw blade 50 and the side of the saw blade 50 facing the air outlet, and the other part is directly guided to the side of the saw blade 50 away from the air outlet adjustment member 805 through the side air outlet pipe 806. The two parts are combined so that when sawing, all chips near the contact surface of the saw blade 50 and the plate can be affected by the blowing, further improving the chip removal effect and preventing chips from entering the inside of the band saw machine along the sawing gap.

[0059] A hand wheel 80520 is fixedly sleeved on one end of the upper roller 8052 extending out of the bellows 803 , and the upper roller 8052 can be conveniently rotated by the hand wheel 80520 to adjust the position of the front air outlet 8054 .

[0060] The driving member 20 includes: a motor 201 ; a driving wheel 202 fixedly matched with the output end of the motor 201 ; and a transmission belt 203 wound between the driving wheel 202 and the lower rotating wheel 30 .

[0061] The contact surface of the transmission belt 203 and the saw blade 50 relative to the lower rotating wheel 30 is parallel and offset.

[0062] A stabilizer 60 is mounted on the base 10 . The stabilizer 60 includes a plurality of rotatable rollers. The rollers are in compression contact with the front and back surfaces of the saw blade 50 , respectively.

[0063] The loading platform 70 includes: a fixed seat 701; a movable seat 702 that can rotate and slide relative to the fixed seat 701; an arc groove 703 provided on the movable seat 702; a rod body 704 fixedly mounted on the fixed seat 701; and a fastening knob 705 matched with the rod body 704;

[0064] The bellows 803 is fixedly connected to the movable seat 702 .

[0065] An external thread is provided on one end of the rod body 704 passing through the arc groove 703, and an internal thread is provided in the tightening knob 705, and the external thread matches the internal thread.

[0066] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
