Description

Technical Field

[0001] The utility model relates to a wood processing device, in particular to a gravity feeding device for a wood slicer. Background Art

[0002] Wooden materials are favored by people for their advantages of heat preservation, moisture resistance, sound insulation, no static induction, no pollution, beauty and luxury, and are widely used in the fields of furniture, architecture, etc. Among them, wood is cut into slices by a saw blade for use. At present, there is a method of cutting wood by manually holding an electric saw. The manual cutting efficiency is low, and the integrity and the thickness of the wood chips are not easy to control.

[0003] In view of the problem of manually slicing wood, there are automatic wood cutters on the market. For example, a wood automatic cutter disclosed in Chinese Utility Model Patent CN206913310U includes a fixed frame and a movable frame. The movable frame is arranged above the fixed frame. A guide rail and a lead screw are arranged between the fixed frame and the movable frame. A cutting blade is arranged on the fixed frame. The fixed frame includes a top plate. A material discharging outlet and a material discharging slideway located below the material discharging outlet are arranged on the top plate. A clamping mechanism, a pushing mechanism and a length positioning mechanism are arranged on the movable frame. The clamping mechanism, the length positioning mechanism and the pushing mechanism are arranged in sequence. A cutting area corresponding to the cutting blade is arranged between the clamping mechanism and the length positioning mechanism. The length positioning mechanism includes a plurality of positioning grooves with a certain distance and a positioning plate clamped in the positioning grooves. The wood to be sliced is placed on the movable frame. The pushing mechanism pushes the wood forward so that the front end of the wood abuts against the positioning plate for positioning. The clamping mechanism fixes the wood on the movable frame. The movable frame moves left and right to make the wood pass through the cutting blade, and the cutting blade cuts off the front end of the wood. The cut part of the wood falls from the material discharging outlet.

[0004] Problems existing in the existing wood slicers: 1. When feeding wood, a pushing mechanism needs to be set to push the wood for feeding, such as a cylinder and a push plate arranged on the cylinder. Every time the wood is cut, the pushing mechanism needs to be started to push once. When feeding through the pushing mechanism, it is necessary to stop for a while to wait for the cylinder to start feeding each time, and the working efficiency is slow. Moreover, the additional pushing mechanism also increases the complexity of the machine and the cost; 2. The distance between the pushing mechanism and the length positioning mechanism is fixed. If the length of the wood to be sliced is longer than the fixed distance, the wood cannot be placed for cutting, and the distance between the pushing mechanism and the length positioning mechanism needs to be reset; 3. Since the placement surface of the movable frame is horizontal, if the wood to be processed is a round log, the round log placed on the placement surface will roll and cause deviation, and the worker needs to adjust and align it before cutting, reducing the slicing efficiency. Summary of the Utility Model

[0005] Based on the problems of low efficiency, high cost, low applicability to the length of wood, the length of the wood not exceeding the distance between the length positioning mechanism and the pushing mechanism, and the round wood rolling on the placement surface in the above-mentioned feeding through the pushing mechanism, the present utility model provides a gravity feeding device for a wood slicing machine.

[0006] The technical solution adopted by the present utility model to solve the above technical problems is as follows: The gravity feeding device of the wood slicing machine includes a feeding frame, and a wood placement groove is provided on the feeding frame. The wood placement groove is inclined downward for the placed wood to slide automatically. The wood placement groove has a receiving part for receiving the placed wood. The receiving part includes a first receiving surface and a second receiving surface. The first receiving surface and the second receiving surface are arranged at an angle to each other, and the bottom of the receiving part is formed between the first receiving surface and the second receiving surface. Both the first receiving surface and the second receiving surface have a high-low slope for guiding the wood to the bottom for positioning.

[0007] A further preferred technical solution of the present utility model is: The receiving part is V-shaped.

[0008] A further preferred technical solution of the present utility model is: The feeding frame is a long strip-shaped frame body with an extended length. The wood placement groove extends along the length direction of the feeding frame and penetrates both ends of the feeding frame to form openings at both ends of the feeding frame. The two ends of the feeding frame in the length direction are offset in the Z-axis direction, the two ends of the feeding frame in the length direction are offset in the X-axis direction, and the two ends of the feeding frame in the length direction are offset in the Y-axis direction.

[0009] A further preferred technical solution of the present utility model is: It further includes a fixed bracket and a movable frame. The movable frame is arranged on the fixed bracket and can move relative to the fixed bracket. The feeding frame is installed on the movable frame. When the movable frame moves relative to the fixed bracket, the slope of the feeding frame is changed.

[0010] A further preferred technical solution of the present utility model is: The upper and lower ends of the wood placement groove have openings, and the wood placement groove is a V-shaped groove.

[0011] A further preferred technical solution of the present utility model is: The included angle between the first receiving surface and the second receiving surface is a right angle.

[0012] A further preferred technical solution of the present utility model is: The inclination angle of the wood placement groove inclined downward is 30 - 60°.

[0013] A further preferred technical solution of the utility model is: the movable frame includes a connecting frame and a mounting plate, the connecting frame is hinged on the fixed bracket, a hinge axis is provided between the connecting frame and the fixed bracket, the mounting plate is installed on the connecting frame, the mounting plate is tilted, the feeding rack is fixed on the mounting plate and has the same inclination as the mounting plate, the mounting plate and the feeding rack can swing up and down around the hinge axis, a support rod is provided between the mounting plate and the fixed bracket, and two ends of the support rod are respectively detachably connected to the mounting plate and the fixed bracket to prop up the mounting plate and the feeding rack.

[0014] A further preferred technical solution of the utility model is: the connecting frame includes a horizontal plate parallel to the mounting plate, the mounting plate is arranged on the horizontal plate, and can swing left and right around a first axis on the horizontal plate, the first axis is perpendicular to the horizontal plate, and an arc groove with the first axis as the center is provided on the mounting plate, and a screw passes through the arc groove and is connected to the horizontal plate to fix the mounting plate and the horizontal plate.

[0015] A further preferred technical solution of the utility model is: connecting seats are fixed on the mounting plate and the fixing bracket, and the two ends of the support rod are respectively connected to the two connecting seat pins.

[0016] Compared with the prior art, the advantages of the utility model are: a wood placement slot is provided on the feeding frame, and the wood placement slot is tilted downward. When the wood is placed in the wood placement slot, the wood can automatically slide down for feeding under the action of its own gravity, and the wood can be automatically unloaded under the action of gravity after each cutting. Compared with waiting for the pushing mechanism to start the pushing efficiency is higher, and the structure is simple and the cost is low. In addition, the feeding method in which the wood is placed in the wood placement slot and automatically slides down does not have the spacing limitation between the pushing mechanism and the length positioning mechanism on the existing slicer. Even if the length of the wood is longer than the length of the wood placement slot, the wood can be placed in the wood placement slot, and it is more applicable.

[0017] The wood placement groove has a receiving part, which includes a first receiving surface and a second receiving surface. The first receiving surface and the second receiving surface are arranged at an angle to each other, and the bottom of the receiving part is formed between the first receiving surface and the second receiving surface.

Finally, the round wood can abut against the first receiving surface and the second receiving surface, automatically complete the adjustment, and always keep sliding straight down, without the need for workers to make additional adjustments and alignment, so as to improve the overall efficiency.

Specific embodiments

[0025] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. Those skilled in the art will understand that these descriptions are only descriptive and exemplary and should not be construed as limiting the protection scope of the present utility model.

[0026] It should be noted that: Similar reference numerals represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0027] Figures 1 - 5 As shown, the gravity feeding device of a wood slicing machine includes a feeding rack 1. A wood placement groove 8 is provided on the feeding rack 1. The round log 9 to be processed can be placed in the wood placement groove 8 and slide for feeding. The wood placement groove 8 is inclined downward. When the round log 9 is placed in the wood placement groove 8, it can automatically slide down along the slope of the wood placement groove 8 for feeding, without the need to set up an additional pushing mechanism to push the round log 9, making the structure simpler and saving the machine cost.

[0028] After each cutting, the log 9 can be automatically discharged under the action of gravity, which is more efficient than waiting for the pushing mechanism to start. In addition, the log 9 is placed in the wood placement groove 8 and fed by sliding, so that the feeding rack 1 is not limited by the distance between the pushing mechanism and the length positioning mechanism on the existing slicing machine. Even if the length of the log 9 is longer than the length of the wood placement groove 8, the wood placement groove 8 can still place the log 9 for feeding the log 9, with stronger applicability.

[0029] The upper and lower ends of the wood placement groove 8 are provided with openings 12.

[0030] Figure 1 、 Figure 3 As shown in the figure, the wood placement groove 8 has a receiving part 2 for receiving and placing the log 9. The receiving part 2 includes a first receiving surface 4 and a second receiving surface 5. The first receiving surface 4 and the second receiving surface 5 are arranged at an angle to each other, and a bottom 3 of the receiving part 2 is formed between the first receiving surface 4 and the second receiving surface 5. Both the first receiving surface 4 and the second receiving surface 5 have a height difference slope for guiding the received log 9 to the bottom 3.

[0031] Figure 5 As shown in the figure, when the log 9 is placed in the wood placement groove 8 for feeding, the log 9 falls on the first receiving surface 4 or the second receiving surface 5 and is guided towards the middle, so that the log 9 can automatically roll towards the middle bottom 3. The log 9 finally abuts against the first receiving surface 4 and the second receiving surface 5 on both sides for positioning at the same time. The log 9 is straightened through the slope guidance of the first receiving surface 4 or the second receiving surface 5, so that the log 9 can slide downward in a straight state without the need for workers to adjust and straighten it additionally, and the left and right rolling of the log 9 during the downward sliding process can be restricted to achieve a better feeding effect.

[0032] Preferably, the receiving part 2 is V-shaped, so that the log 9 placed in the wood placement groove 8 can automatically roll and correct towards the bottom 3 of the receiving part 2 for receiving through the receiving part 2, and the included angle between the first receiving surface 4 and the second receiving surface 5 is a right angle.

[0033] Figure 1As shown, preferably, the feeding rack 1 is a long strip-shaped rack with an extended length. The wood placement groove 8 extends along the length direction of the feeding rack 1 and penetrates through both ends of the feeding rack 1, so as to form openings 12 at both ends of the feeding rack 1. The two ends of the feeding rack 1 in the length direction are misaligned in the Z-axis direction, the two ends of the feeding rack 1 in the length direction are misaligned in the X-axis direction, and the two ends of the feeding rack 1 in the length direction are misaligned in the Y-axis direction, so as to form the slopes of the wood placement groove 8, the first receiving surface 4 and the second receiving surface 5. That is, the two ends of the feeding rack 1 in the length direction are misaligned in the Y-axis direction, and the two ends of the feeding rack 1 in the length direction are misaligned in the Z-axis direction, so that the feeding rack 1 is inclined obliquely downward, and the wood placement groove 8 on the feeding rack 1 is also inclined obliquely downward. The two ends of the feeding rack 1 in the length direction are misaligned in the X-axis direction, so that both the first receiving surface 4 and the second receiving surface 5 have a high-low slope for guiding the received round logs 9 to the bottom 3, that is to say, while tilting the feeding rack 1 downward, it is tilted to the left or right.

[0034] In addition, the opening 12 at the lower end of the feeding rack 1 allows the round logs 9 to slide out of the feeding rack 1 downward for cutting, and the opening 12 at the upper end of the feeding rack 1 enables the feeding rack 1 to place round logs 9 longer than the feeding rack 1.

[0035] Preferably, the wood placement groove 8 is a V-shaped groove with an opening facing forward, which is convenient for workers to put the round logs 9 into the wood placement groove 8 from the side of the feeding rack 1.

[0036] Figure 4 As shown, preferably, the inclination angle of the wood placement groove 8 inclined downward is 30-60°, and most preferably, the inclination angle of the wood placement groove 8 inclined downward is 35°, and the inclination angle is set as a. The inclination angle of the wood placement groove 8 inclined downward is related to the sliding speed of the placed round logs 9. The larger the inclination angle, the faster the sliding speed of the round logs 9, and the smaller the inclination angle, the slower the sliding speed of the round logs 9. The above inclination angle enables the sliding speed of the round logs 9 placed on the wood placement groove 8 not to generate a large impact due to being too fast, nor to affect the processing efficiency due to the too slow sliding speed of the round logs 9.

[0037] Figure 2 As shown, the slope of the feeding rack 1 is adjustable. Preferably, the feeding device further includes a fixed bracket 7 and a movable frame 6. The movable frame 6 is arranged on the fixed bracket 7 and can move relative to the fixed bracket 7. The feeding rack 1 is installed on the movable frame 6. The movable frame 6 can change the inclination of its own various directions by moving relative to the fixed bracket 7 to adjust the slope of the feeding rack 1, such as the inclination angle of the wood placement groove 8 arranged obliquely downward, or the slope of the first receiving surface 4 and the second receiving surface 5 for guiding the round logs 9 to the middle.

[0038] For example, the movable frame 6 described in this embodiment includes a connecting frame 13 and a mounting plate 14. The connecting frame 13 is hinged to the fixed bracket 7. There is a hinge shaft 15 between the connecting frame 13 and the fixed bracket 7. The mounting plate 14 is installed on the connecting frame 13. The mounting plate 14 is arranged obliquely. The feeding frame 1 is fixed to the mounting plate 14, and the feeding frame 1 has the same inclination as the mounting plate 14. The mounting plate 14 and the feeding frame 1 can swing up and down around the hinge shaft 15. A support rod 19 is provided between the mounting plate 14 and the fixed bracket 7. The two ends of the support rod 19 are detachably connected to the mounting plate 14 and the fixed bracket 7 respectively to support the mounting plate 14 and the feeding frame 1 upward.

[0039] Since the mounting plate 14 and the feeding frame 1 can swing up and down around the hinge shaft 15, the inclination angle of the wood placement groove 8 arranged obliquely downward is adjusted by the up and down swing of the mounting plate 14 and the feeding frame 1. After adjusting the angle, a support rod 19 with a corresponding length is selected to be connected between the mounting plate 14 and the fixed bracket 7 to support the mounting plate 14 and the feeding frame 1, so that the wood placement groove 8 maintains the adjusted inclination angle, thereby controlling the sliding speed of the round log 9 in the wood placement groove 8. The support rod 19 is used here to support the mounting plate 14 upward and to limit the swing of the mounting plate 14 around the hinge shaft 15 relative to the fixed bracket 7, playing a locking role.

[0040] In other words, support rods 19 with different lengths are supported between the mounting plate 14 and the fixed bracket 7 to adjust the inclination angle of the wood placement groove 8 obliquely downward. The shorter the support rod 19, the smaller the angle at which the support rod 19 supports the mounting plate 14 upward, that is, the smaller the angle between the mounting plate 14 and the horizontal plane, and the smaller the downward inclination angle of the feeding frame 1 and the wood placement groove 8 on the feeding frame 1. The longer the support rod 19, the larger the angle at which the support rod 19 supports the mounting plate 14 upward, that is, the larger the angle between the mounting plate 14 and the horizontal plane, and the larger the downward inclination angle of the feeding frame 1 and the wood placement groove 8 on the feeding frame 1.

[0041] Figure 2 、 Figure 4 As shown, preferably, connecting seats 20 are fixed on both the mounting plate 14 and the fixed bracket 7. The two ends of the support rod 19 are respectively pin-connected to the two connecting seats 20 to lock the rotation of the mounting plate 14 and the feeding frame 1 around the hinge shaft 15. The rotation of the connecting frame 13 around the hinge shaft 15 is not limited to the above-mentioned support rod 19 for support and adjustment. It can also be driven and rotated by a reduction motor, or the mounting plate 14 can be jacked up upward at the bottom of the mounting plate 14 by a jacking cylinder.

[0042] The hinge shaft 15 is parallel to the X-axis.

[0043] Figure 1 、 Figure 3As shown, in addition, the connecting frame 13 includes a cross plate 16 parallel to the mounting plate 14. The mounting plate 14 is arranged on the cross plate 16 and can swing left and right around the first shaft 10 on the cross plate 16. The first shaft 10 is perpendicular to the cross plate 16. An arc-shaped groove 11 centered on the first shaft 10 is provided on the mounting plate 14. A screw passes through the arc-shaped groove 11 and is connected to the cross plate 16 to fix the mounting plate 14 and the cross plate 16.

[0044] By swinging the mounting plate 14 and the feeding frame 1 left or right around the first shaft 10, the inclination of the first receiving surface 4 and the second receiving surface 5 guiding towards the middle bottom 3 is adjusted. At the same time, the downward inclination angle of the wood placement groove 8 also changes. When it is necessary to adjust the inclination of the first receiving surface 4 and the second receiving surface 5, loosen the screw so that the mounting plate 14 can rotate relative to the cross plate 16. At this time, the screw inserted in the arc-shaped groove 11 can limit the angular range of the left and right swing of the mounting plate 14 and the feeding frame 1. After adjustment, tighten the screw, and the head of the screw presses on the mounting plate 14 to fix the mounting plate 14 and the cross plate 16 together, locking the relative rotation.

[0045] Threaded holes 18 connected to the screws are provided on the cross plate 16.

[0046] The connecting frame 13 further includes a vertical plate 17. The lower side of the vertical plate 17 is hinged to the fixed bracket 7. The cross plate 16 is fixed to the other side of the vertical plate 17, and the vertical plate 17 is perpendicular to the cross plate 16.

[0047] When setting the inclination of the wood placement groove 8, the first receiving surface 4 and the second receiving surface 5, before setting, the mounting plate 14 and the feeding frame 1 are horizontally arranged, and the wood placement groove 8 on the feeding frame 1 is horizontally arranged. At this time, the first receiving surface 4 is a vertical surface, and the second receiving surface 5 is a horizontal surface. The first shaft 10 is vertically arranged. By supporting a support rod 19 between the mounting plate 14 and the fixed bracket 7, one end of the mounting plate 14 is lifted upward, and the mounting plate 14 is arranged obliquely downward, forming an obliquely downward inclination angle. At this time, both the feeding frame 1 and the wood placement groove 8 are adjusted from the horizontal arrangement to the obliquely downward arrangement, and the first shaft 10 changes from the vertical arrangement to the oblique arrangement. Then swing the mounting plate 14 around the first shaft 10 to the left, so that the feeding frame 1 also swings to the left around the first shaft 10. Since the first shaft 10 is obliquely arranged, when the feeding frame 1 swings to the left around the first shaft 10, the upper end of the feeding frame 1 moves to the left and the height decreases, making the second receiving surface 5 change from being equal in height on both sides to being lower on the left and higher on the right. The first receiving surface 4 located on the left side of the second receiving surface 5 changes from a vertical surface to an inclined surface that is higher on the left and lower on the right. During the process of the feeding frame 1 gradually rotating to the left around the first shaft 10, the inclination of the second receiving surface 5 that is lower on the left and higher on the right will become larger and larger, and the inclination of the first receiving surface 4 that is higher on the left and lower on the right will become smaller and smaller.

Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the present utility model and its core idea. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
