Description

Technical Field

[0001] The utility model belongs to the technical field of grinding bamboo and wooden sharpening knives, and particularly relates to an automatic sharpening machine and method for the integrated front and rear blade surfaces of a bamboo and wooden sharpening knife. Background Art

[0002] After any tool is used for a long time, the cutting edge of the tool will wear out, and the precision and quality of the parts and materials processed by the worn tool will be greatly reduced. The bamboo sharpening knife is a special tool with a six-blade or eight-blade structure. The blade is welded on the leaf at a certain angle, and the blade is in the same plane of the tool. Through this structure, the bamboo sharpening knife can quickly sharpen bamboo and wood products. For example, the sharpness of bamboo chopsticks is used to distinguish between the feeding head and the non-feeding head, barbecue bamboo skewers, etc. During the sharpening process, the sharpening accuracy of the front and rear blades of the tool must be ensured. Due to this special structure, manual sharpening is very difficult.

[0003] The existing automatic knife sharpening machines only have automatic repetitive movement of the sharpening stroke and automatic blade change sharpening. The knife still needs to be manually aligned, which is very strict with people's visual control, and there is a risk of being splashed by sparks or water if you get too close. In addition, both the front and rear blades of the sharpened knife need to be sharpened. If only one blade is sharpened, it will cause the defect that the blade is not in the same plane, resulting in low quality of the produced bamboo and wood. The existing technology is to manually disassemble the sharpened knife with the sharpened front blade to another CNC sharpening machine or turn it over. This operation not only increases the machine cost, land cost and labor cost, but also increases the risk of injury when workers remove the sharp blade. In summary, it is necessary to develop an automatic sharpening machine that integrates the front and rear blades of bamboo and wood sharpened knives. Utility Model Content

DETAILED DESCRIPTION

[0035] The following are specific embodiments of the utility model and the accompanying drawings to further describe the technical solution of the utility model, but the utility model is not limited to these embodiments.

[0036] Embodiment 1

[0037] like Figure 1 As shown, the sharpening tool A has a plurality of cutting edges distributed circumferentially, and each cutting edge is formed by a rake face A1 and a relief face A2.

[0038] like Figure 5 and Figure 7 As shown, the present automatic knife sharpening machine for sharpening front and rear blades of bamboo and wood knives comprises a machine platform 1. A chamber for installing electric control is provided inside the bottom of the machine platform 1, a foldable control display screen is provided on the side of the machine platform 1, and a protective cover 10 that can be opened and closed is also provided on the machine platform 1, and at least part of the protective cover 10 is transparent to facilitate observation.

[0039] like Figure 1 and Figure 3-Figure 6 As shown, the automatic knife sharpening machine for the front and rear blades of a bamboo and wood sharpening knife also includes a sharpening knife fixing component 2, a lateral driving mechanism 3, a rotating driving mechanism 4, a sharpening knife alignment component 5, a front blade sharpening component 6 and a rear blade sharpening component 7, and a control system (such as a PLC control system), and the control system controls the above-mentioned various mechanisms and components.

[0040] The sharpening knife fixing assembly 2 is used to fix the sharpening knife A to be sharpened, specifically, as Figure 3As shown, the sharpening tool fixing assembly 2 includes a vertically arranged baffle plate 20, on which a rotation positioning shaft 21 and a fastener 22 threadedly connected to the rotation positioning shaft 21 are arranged. The rotation positioning shaft 21 is a stepped shaft, so as to be able to position any end face of the tool holder of the sharpening tool A in the thickness direction, and the fastener 22 is, for example, a bolt, etc., which is tightened by thread and the cap end of the fastener 22 fastens the other end face of the tool holder of the sharpening tool A in the thickness direction. Of course, some elastic gaskets or plane bearings and other components can also be added to prevent the fastener 22 from loosening.

[0041] The sharpening knife fixing assembly 2 comprises a rotational positioning shaft 21 and a rotational driving mechanism 4, and the rotational driving mechanism 4 is a motor driving mechanism to drive the rotational positioning shaft 21 to rotate. The motor driving mechanism is, for example, a stepping motor or a servo motor, which is connected to the rotational positioning shaft 21 through a belt drive, a gear drive or other drive methods. The rotational driving mechanism 4 is mounted on the traverse driving mechanism 3.

[0042] The sharpening knife fixing assembly 2 is connected to the traverse driving mechanism 3. Figure 6 As shown, the lateral drive mechanism 3 drives the sharpening tool fixing assembly 2 to move linearly in the horizontal direction. This embodiment uses the active movement of the sharpening tool A to approach the sharpening assembly to ensure the rotational stability of the sharpening assembly. Specifically, the lateral drive mechanism 3 includes a transverse screw sleeve 30 fixedly connected to the baffle 20, and a transverse screw rod 31 that penetrates the transverse screw sleeve 30 and is threadedly connected to the transverse screw sleeve 30, both ends of the transverse screw rod 31 are rotatably connected to the machine 1, and the transverse screw rod 31 is connected to the driving motor through a transmission structure, and a lateral guide assembly 32 is provided between the baffle 20 and the machine 1.

[0043] When the driving motor is started, the transverse screw 31 is driven to rotate in situ, and the transverse screw sleeve 30 is then moved linearly, and finally drives the linear movement of the baffle 20. At the same time, the transverse guide assembly 32 of this embodiment has two groups, such as a combination structure of a guide post and a guide sleeve, and of course, a combination structure of a guide rail and a slider, to ensure the linear movement of the baffle 20.

[0044] In order to ensure the safety of tool alignment, at least part of the transverse guide assembly 32 is fixed to the transverse seat 33, for example, the guide sleeve is fixed to the transverse seat, and the transverse screw sleeve 30 is also fixed to the transverse seat. A lifting seat 34 is provided on the transverse seat, and the baffle 20 is fixed to the lifting seat. The lifting seat is connected to the lifting drive assembly fixed on the transverse seat. When the knife needs to be aligned, the rotary drive mechanism 4 drives the rotary positioning shaft 21 to rotate so that one of the blades of the sharpening knife A is in a vertical state. When the sharpening knife alignment assembly 5 is in the set position, the lifting drive assembly drives the entire baffle 20 to descend and makes the outer tip corner of the blade contact the sharpening knife alignment assembly 5 first. When all the edges of the blade are aligned with the sharpening knife alignment assembly 5, it means that the knife alignment is completed. Of course, in the process of knife alignment, photoelectric sensors or other sensors or cameras can be used to detect whether there is a gap between the blade and the sharpening knife alignment assembly 5. If there is a gap, the rotary drive mechanism 4 drives the rotary positioning shaft 21 to rotate. Of course, the sharpening knife alignment assembly 5 can also be moved to finally eliminate the gap.

[0045] Specifically, Figure 3 As shown, the sharpening knife setting assembly 5 comprises a vertically arranged tool setting reference 50 and a linear drive assembly 51 for driving the tool setting reference 50 to move linearly. The linear drive assembly 51 is, for example, a linear motor drive assembly.

[0046] Specifically, the rake face grinding assembly 6 includes a rake face grinding wheel 60 whose inclination angle is consistent with the rake face inclination angle, and a first drive motor 61 that drives the rake face grinding wheel 60 to rotate, the first drive motor 61 is a servo motor, and the first drive motor 61 is fixed to the machine 1 through a first angle adjustable mechanism 62, and the first angle adjustable mechanism 62 here is, for example, a dividing plate type angle adjuster; the back face grinding assembly 7 includes a back face grinding wheel 70 whose inclination angle is consistent with the back face inclination angle, and a second drive motor 71 that drives the back face grinding wheel 70 to rotate, and the second drive motor 71 is fixed to the machine 1 through a second angle adjustable mechanism 72. The second angle adjustable mechanism 72 is, for example, a dividing plate type angle adjuster.

[0047] Before sharpening the knives, the corresponding inclination angles of the rake face sharpening wheel 60 and the flank face sharpening wheel 70 are adjusted according to different sharpening knives A.

[0048] Preferably, the front blade grinding assembly 6 of this embodiment has a conductive element 1 (not shown in the figure). For example, only when the working surface of the front blade grinding wheel 60 coincides with the front blade A1, the conductive element 1 will be electrically connected to the front blade A1. On the contrary, for example, when there is a gap between the working surface of the front blade grinding wheel 60 and the front blade A1, the conductive element 1 will not be electrically connected. At this time, the position of the front blade grinding wheel 60 needs to be adjusted. Specifically, the first angle adjustable mechanism 62 is arranged on the two-dimensional linear adjustment assembly 63. The two-dimensional linear adjustment assembly 63 includes vertical adjustment and lateral adjustment. The specific structure of the two-dimensional linear adjustment assembly 63 adopts a mutually matched slide rail substructure 630, and corresponding adjustment is set in the corresponding dimension. The driving screw 631, for example, is adjusted to drive the slider to move relative to the slide rail to achieve vertical or horizontal position adjustment. At this time, the working surface of the rake face grinding wheel 60 can be brought into contact with the rake face. The conductive element 1 adopts a non-contact wireless conduction method, and the conductive element 1 is implanted in the rake face grinding wheel 60. When the rake face grinding wheel 60 stops rotating, it is energized and electrically connected to the outer tip angle or rake face of the blade. When the conductive element 1 is electrically connected to the rake face of the blade, the transverse driving mechanism 3 drives the sharpening knife fixing assembly 2 to move linearly relative to the rake face grinding assembly 6. At this time, the rake face grinding wheel 60 starts to rotate (the power supply of the conductive element 1 is disconnected), and the grinding of the rake face is completed. The conductive element 1 can be electrically connected to or canceled from the detachable mobile power supply provided on the rake face grinding wheel 60.

[0049] Secondly, the back face sharpening assembly 7 has a conductive element 2. When the conductive element 2 is electrically connected to the back face of the blade, the lateral drive mechanism 3 drives the sharpening knife fixing assembly 2 to move linearly relative to the back face sharpening assembly 7. The arrangement of the conductive element 2 is similar to that of the conductive element 1. Similarly, the second angle adjustable mechanism 72 is arranged on the two-dimensional linear adjustment group 73. The structure of the two-dimensional linear adjustment group 73 is the same as that of the two-dimensional linear adjustment assembly 63, and the principle can be referred to the two-dimensional linear adjustment assembly 63.

[0050] When the power is on, it means that the working surface of the rake face grinding wheel 60 of the rake face grinding assembly 6 and the rake face are in a state of coincident contact, and the working surface of the rake face grinding wheel 70 of the rake face grinding assembly 7 and the rake face are in a state of coincident contact, so as to prevent the two from being out of contact or

[0051] like Figure 2 As shown, when working:

[0052] Rake face grinding: the rotary drive mechanism 4 drives the sharpening tool A to rotate 90° in the first rotation direction (counterclockwise) so that the rake face of the blade is distributed laterally; the sharpening tool A is linearly moved to force the rotating rake face grinding wheel 60 to process the rake face.

[0053] To grind the back face, the rotary drive mechanism 4 drives the sharpening tool A to rotate 90° in the second rotation direction (clockwise) so that the back face of the blade is distributed laterally. The linear movement of the sharpening tool A forces the rotating back face grinding wheel 70 to process the front face.

[0054] Embodiment 2

[0055] Based on Example 1, Figure 1 Figure 7 As shown, this embodiment further provides an automatic sharpening method for the front and rear blades of a bamboo sharpening knife, using the integrated automatic sharpening machine for the front and rear blades of a bamboo sharpening knife of the first embodiment, and the automatic sharpening method comprises the following steps:

[0056] S1, fixing the sharpening knife A to be sharpened to the sharpening knife fixing assembly 2;

[0057] S2, the lateral drive mechanism 3 drives the sharpening knife fixing assembly 2 of S1 to approach the sharpening knife setting assembly 5, and the rotation drive mechanism 4 drives one of the blades of the sharpening knife A to be vertically distributed and consistent with the setting reference 50 of the sharpening knife setting assembly 5;

[0058] S3, the rotary drive mechanism 4 in S2 drives the sharpening tool A to rotate in the first rotation direction by a first set angle, such as 90°, so that the front cutting surface of the blade is distributed laterally; or the rotary drive mechanism 4 in S2 drives the sharpening tool A to rotate in the second rotation direction by a second set angle, such as 90°, so that the back cutting surface of the blade is distributed laterally;

[0059] S4, the sharpening knife fixing assembly 2 in S3 moves linearly under the drive of the transverse driving mechanism 3, and the direction of the linear movement includes a first direction moving toward the front blade sharpening assembly 6 and a second direction moving toward the rear blade sharpening assembly 7. When the sharpening knife fixing assembly 2 moves in the first direction with the blade rotated to the set angle 1 and contacts the front blade sharpening assembly 6, the front blade is ground;

[0060] When the sharpening tool fixing assembly 2 moves in the second direction with the blade rotated to the set angle 2 and contacts the back face grinding assembly 7, the back face grinding is performed.

[0061] When the front blade face sharpening assembly 6 and the front blade face of the blade are electrically connected, the lateral drive mechanism 3 drives the sharpening knife fixing assembly 2 to move linearly relative to the front blade face sharpening assembly 6; and when the rear blade face sharpening assembly 7 and the rear blade face are electrically connected, the lateral drive mechanism 3 drives the sharpening knife fixing assembly 2 to move linearly relative to the rear blade face sharpening assembly 7.

[0062] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
