Description

Technical Field

[0001] This utility model relates to the field of double-sided grinding of pruning blades, and more particularly to an automatic feeding device suitable for double-sided grinding of pruning blades. Background Technology

[0002] With the advancement of technology and the development of the landscaping and horticulture industry, a series of semi-automatic or fully automatic pruning blade sharpening equipment has gradually emerged in the market. These devices have improved the sharpening efficiency and quality of pruning blades to a certain extent. However, despite the significant progress these devices have made in sharpening technology, there are still many shortcomings in feeding, which limits the further improvement of their overall performance and efficiency.

[0003] On the one hand, some pruning blade grinding equipment uses a simple mechanical pushing method for feeding. While this method can basically meet the feeding requirements, the lack of precise control and separation mechanisms often prevents accurate pushing and separating of the pruning blades. In actual operation, this can easily lead to damage or misalignment of the blades during the pushing process, thus affecting the subsequent grinding effect and the lifespan of the blades. On the other hand, other pruning blade grinding equipment relies on manual feeding. This method is not only cumbersome, requiring operators to constantly put pruning blades into the equipment, but it also cannot achieve continuous production, greatly reducing work efficiency. In addition, manual feeding is easily affected by human factors, such as operator fatigue and distraction, which can lead to inaccurate or missed feeding, thus affecting grinding quality and production efficiency.

[0004] For example, the utility model patent with application number 202323012474.1 discloses a crusher blade grinding machine, which includes a turntable device and a grinding device. The turntable device includes a fixed base, a turntable body rotatably disposed on the fixed base, and a first driver for driving the turntable body. The turntable body is provided with multiple blade holders, which are arranged sequentially along the circumference of the turntable body. The grinding device includes a base frame, a grinding wheel rotatably disposed on the base frame, and a second driver for driving the grinding wheel. The grinding wheel is disposed on the side of one of the blade holders along the axial direction of the turntable body.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0029] As shown in the figure, an automatic feeding device for double-sided grinding of pruning blades includes: a feeding mechanism 1, and a grinding mechanism 2 disposed on one side of the feeding mechanism 1.

[0030] The polishing mechanism 2 includes: a polishing base 20, a polishing motor disposed at the bottom of the polishing base 20, and a polishing stone 21 disposed on the polishing motor. The polishing stone 21 is arranged in a circular shape and rotates in the opposite direction.

[0031] The grinding motor is located inside the grinding base 20, and the output shaft of the grinding motor passes through the grinding base 20. The grinding motor is fixedly connected to the grinding stone 21. By rotating the grinding motor, the grinding stone 21 is rotated, thereby grinding the pruning blade.

[0032] The feeding mechanism 1 includes: a feeding base 10, a pushing component 11 disposed on one side of the feeding base 10, and a separating component 12 disposed on one side of the pushing component 11; the pushing component 11 and the separating component 12 are disposed on the feeding base 10, and the separating component 12 and the grinding mechanism 2 are located on the same axis;

[0033] In a preferred embodiment of this utility model, the feeding base 10 and the polishing base 20 are misaligned.

[0034] It should be noted that the feeding base 10 and the grinding base 20 are staggered, so that when grinding the pruning blade, the pruning blade can be directly pushed from the feeding base 10 to the grinding base 20, and can be directly pushed between the two grinding stones 21 for grinding.

[0035] In a preferred embodiment of the present invention, the pushing assembly 11 includes a pushing shell 111, a pushing member disposed inside the pushing shell 111, and a push plate 114 fixedly connected to the pushing member; the push plate 114 contacts the pruning blade and pushes it.

[0036] In a preferred embodiment of the present invention, the pushing component includes: a pushing cylinder 112, and telescopic shafts 113 disposed on both sides of the pushing cylinder 112; the ends of the telescopic shafts 113 and the pushing cylinder 112 are both fixedly connected to the pushing shell 111, and the output shaft of the pushing cylinder 112 and the front end of the telescopic shaft 113 are both fixedly connected to the push plate 114.

[0037] It should be noted that the push shell 111 is fixedly connected to the top side of the feeding base 10, and the pusher is set inside the push shell 111. On the side of the push shell 111, specifically on the side of the push shell 111 on the feeding base 10, there is a push plate 114. The push plate 114 is not directly connected to the push shell 111, but is fixedly connected to the pusher. The pusher includes a push cylinder 112 and two telescopic shafts 113. The output shaft of the push cylinder 112 is fixedly connected to the push plate 114. The telescopic shafts 113 are set on both sides of the push cylinder 112. The bottom of the telescopic shafts 113 is fixedly connected to the push shell 111, and the extendable part at the top of the telescopic shafts 113 is fixedly connected to the push plate 114.

[0038] During the grinding process, the parallel push plate 114 of the pruning blade is placed on the feeding base 10, and the pruning blade is placed on the side of the push plate 114 away from the push shell 111. During the grinding process, the push cylinder 112 pushes the push plate 114, thereby pushing the pruning blade to the separation component 12 for separation.

[0039] In a preferred embodiment of the present invention, the separation component 12 includes: an upper pusher 13 and a lower presser 14 disposed above the upper pusher 13; the lower presser 14 is disposed opposite to the pusher plate 114.

[0040] In a preferred embodiment of the present invention, the pusher 13 includes: a limiting shell 132, an upper push plate 131 slidably connected to the limiting shell 132, and an upper push cylinder 133 fixedly connected to the upper push plate 131; the limiting shell 132 is fixedly connected to the side of the feeding base.

[0041] It should be noted that the limiting shell 132 is fixedly connected to the side of the feeding base 10, and the side of the limiting shell 132 is parallel to the side of the pushing shell 111. The upper pushing cylinder 133 is fixedly connected to the limiting shell 132, and the output shaft of the upper pushing cylinder 133 is arranged to pass through the limiting shell 132. The upper pushing plate 131 is slidably connected to the inner side of the limiting shell 132, and the bottom of the upper pushing plate 131 is fixedly connected to the upper pushing cylinder 133. The upper pushing plate 131 is set to fit against the side of the feeding base 10, and the top of the upper pushing plate 131 is fitted against the side of the feeding base 10 with a rectangular groove. The width of the rectangular groove is the same as the width of a pruning blade.

[0042] When the push plate 114 pushes the pruning blade to the side of the feeding base 10 where the upper pusher 13 is located, the upper pusher cylinder 133 pushes the upper pusher plate 131 upward, so that the foremost pruning blade, which is closest to the upper pusher plate 131, is pushed into the rectangular groove of the upper pusher plate 131, and the upper pusher plate 131 continues to move upward, separating several pruning blades.

[0043] In a preferred embodiment of the present invention, the pressing member 14 includes: a connecting plate 141, a misaligned plate 142 fixedly connected to the connecting plate 141, and a feeding cylinder fixedly connected to the connecting plate 141; a feeding plate 143 is fixedly connected to the output shaft of the feeding cylinder, and a fixing member 144 is provided on the feeding plate 143.

[0044] In a preferred embodiment of the present invention, a misalignment groove is provided between the connecting plate 141 and the misalignment plate 142. The width of one pruning blade is less than the width of the misalignment groove and less than the width of two pruning blades. A moving groove is provided between the connecting plate 141 and the misalignment plate 142. The feeding cylinder and the feeding plate 143 are connected through the moving groove.

[0045] In a preferred embodiment of the present invention, the fixing member 144 includes a threaded rod, straight rods disposed on both sides of the threaded rod, and a fixing plate rotatably connected to the threaded rod. The threaded rod is threadedly connected to the feeding plate 143.

[0046] In a preferred embodiment of the present invention, a hidden groove is provided at the bottom of the misalignment plate 142, and the fixing plate is located in the hidden groove in the initial state.

[0047] It should be noted that the connecting plate 141 is fixedly connected to the feeding base 10, and a gap is provided between the connecting plate 141 and the side of the feeding base 10. This gap is used to avoid obstructing the upward movement of the pushing plate 131 of the pushing member 13. The misalignment plate 142 is fixedly connected to the side of the connecting plate 141 near the pruning blade. The connecting plate 141 and the misalignment plate 142 are arranged in parallel, and a gap is left between the connecting plate 141 and the misalignment plate 142. This gap is the misalignment groove, and the width of the misalignment groove is greater than the width of one pruning blade but less than the width of two pruning blades. Due to the stacking of pruning blades, some blades may be completely stuck together and difficult to open manually. As the upper push plate 131 pushes the pruning blades upward, the pruning blades are pushed into the misalignment groove. When two or more pruning blades are pushed in, the outer pruning blade is blocked by the misalignment plate 142, and only the inner pruning blade can enter the misalignment groove. The blocked pruning blades are then separated by the upward movement of the upper push plate 131.

[0048] A moving groove is provided in the middle of both the connecting plate 141 and the misalignment plate 142. The feeding cylinder and the feeding plate 143 are fixedly connected by a short shaft. The short shaft passes through the moving groove, and its two ends are fixedly connected to the feeding cylinder and the feeding plate 143, respectively. The feeding cylinder is fixedly connected to the connecting plate 141, and the feeding plate 143 is threadedly connected to the threaded rod. As the threaded rod rotates, it can drive the fixed plate to move up and down, disengaging from the hidden groove. When separating the pruning blade, the fixed plate is located in the hidden groove, which can prevent the fixed plate from obstructing the separation of the pruning blade. As the fixing plate disengages from the hidden groove, the fixing plate and the upper push plate 131 fix the pruning blade. As the feeding cylinder extends and retracts, it drives the feeding plate 143 to move towards the grinding mechanism 2, which in turn drives the fixing plate to move. The fixing plate then pushes the pruning blade to move. The side of the fixing plate that contacts the pruning blade has a groove. As the fixing plate moves down, the pruning blade moves into the groove. As the fixing plate moves, the groove drives the pruning blade to move, and the pruning blade is slowly fed into the pruning blade for gradual grinding as the feeding cylinder moves back and forth.
