Detailed Implementation
[0028] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other. Example
[0029] A sharpening machine for processing cigarette clip pins, such as Figure 1-7 As shown, the workbench 1 includes a base plate 2 mounted on an opening 23; the upper surface of the base plate 2 is arc-shaped; a wear-resistant layer 201 is adhered to the upper surface of the base plate 2. By adhering the wear-resistant layer 201 to the upper surface of the base plate 2, only the wear-resistant layer 201 needs to be replaced after a certain period of operation, resulting in low maintenance costs.
[0030] Specifically, the bottom of the base plate 2 is provided with a threaded hole for connecting with the worktable 1; the bottom of the base plate 2 is also provided with a boss for engaging with the opening; the wear-resistant layer 201 is made of nylon.
[0031] Specifically, two mounting brackets 3 are installed above the workbench 1, and a first rotating shaft 5 is rotatably mounted between the two mounting brackets 3. One end of the first rotating shaft 5 is connected to a first motor 4. Two pressure rollers 6 are detachably mounted on the first rotating shaft 5. The outer ring of the pressure rollers 6 can undergo elastic deformation. The upper surface of the base plate 2 presses against the edge of the pressure rollers 6 or contacts the edge of the pressure rollers 6. In this embodiment, the pressure rollers 6 are made entirely of sponge, but can also be replaced with other materials that can undergo elastic deformation. By driving the first rotating shaft 5 to rotate through the first motor 4, the two pressure rollers 6 can be driven to rotate. The rotation of the pressure rollers 6 causes the pins inserted between the pressure rollers 6 and the base plate 2 to rotate and move simultaneously.
[0032] Specifically, in order to process pins of different thicknesses, the height of the pressure roller 6 needs to be finely adjusted to regulate the tightness of the compression between the pressure roller 6 and the base plate 2. The mounting bracket 3 has a sliding groove in which a mounting block 26 can be slidably mounted. A top plate 27 is mounted above the mounting block 26, and a support spring 29 is mounted below it. The lower end of the screw 28 passes through the upper part of the mounting bracket 3 and abuts against the top plate 27; the screw 28 is threadedly connected to the mounting bracket 3. When the pressure roller 6 needs to be adjusted downwards, the screw 28 is rotated, causing it to move downwards against the top plate 27 and mounting block 26, further compressing the support spring 29. When the pressure roller 6 needs to be adjusted upwards, the screw 28 is rotated, causing it to move upwards, and the top plate 27 and mounting block 26 move upwards under the elastic force of the support spring 29 until the top plate 27 re-abuts against the screw 28. Correspondingly, shims or other methods can be used to adjust the mounting height of the first motor 4. Specifically, the radius of the pressure roller 6 is the same as the radius of the upper surface of the base plate 2. The radius of the pressure roller 6 can also be larger or smaller than the radius of the upper surface of the base plate 2. A smaller radius of the pressure roller 6 will result in a smaller grinding tip, while a larger radius will increase the design cost.
[0033] Specifically, a second rotating shaft 7 is rotatably mounted above the worktable 1; several needle rollers 8 are detachably and fixedly mounted on the second rotating shaft 7; several needle grooves are opened on the needle rollers 8; the needle rollers 8 press the edge of the pressure roller 6. When processing needles of different thicknesses, the needle rollers 8 with suitable needle groove sizes can be selected and replaced.
[0034] Specifically, in order to make the needles move more smoothly, a slope 202 is provided on one side of the upper surface of the base plate 2, and a protruding tooth 203 is provided on the other side; the protruding tooth 203 is inserted into the gap between several needle rollers 8.
[0035] Specifically, an infeed groove 12 is installed at an angle on the upper surface of the worktable 1 near the needle roller 8, and an outlet groove 13 is installed at an angle on the side away from the needle roller 8; limit plates 14 are installed on both sides of the worktable 1. The angled arrangement of the infeed groove 12 and the outlet groove 13 facilitates the movement of the needles. The limit plates 14 prevent the needles from tilting out from both sides.
[0036] Specifically, a grinding wheel 11 is rotatably mounted under the workbench 1; the surface of the grinding wheel 11 is arc-shaped, and the radius of the arc is equal to the radius of the upper surface of the base plate 2; the mounting height of the upper surface of the grinding wheel 11 is flush with the base plate 2; and a clearance groove 204 for the grinding wheel 11 to rotate is provided at the bottom of the base plate 2.
[0037] Specifically, the worktable 1 is mounted on the support plate 16 below; the support plate 16 is equipped with a height adjustment component for adjusting the installation height of the grinding wheel 11; and a drive component for driving the grinding wheel 11 to rotate is also installed below the worktable 1.
[0038] Specifically, there are two sets of adjustment components, arranged opposite each other. Each set of adjustment components includes a first mounting plate 19 and a second mounting plate 20 fixed to the wall of a sliding groove opened on the support plate 16; a lead screw 21 is rotatably mounted between the first mounting plate 19 and the second mounting plate 20; a slider 18 is slidably mounted on the sliding groove; one end of the lead screw 21 is threadedly connected to the slider 18; a handle 22 is mounted on the lead screw 21; a bearing seat is mounted on the upper section of the slider 18; and a third rotating shaft 17 for mounting the grinding wheel 11 is rotatably mounted between the two opposing bearing seats. When it is necessary to adjust the mounting height of the third rotating shaft 17, hold the handle 22, rotate the lead screw 21, drive the slider 18 to move up and down, and the mounting height of the third rotating shaft 17 and the grinding wheel 11 mounted on it can be adjusted.
[0039] Specifically, the drive assembly includes a second motor 15 mounted below the worktable 1 and a belt drive assembly or chain drive assembly connecting the second motor 15 and the third rotating shaft 17.
[0040] Specifically, the feed trough 12 is detachably mounted on the workbench 1 via the first bracket 25; the discharge trough 13 is detachably mounted on the workbench 1 via the second bracket 24.
[0041] Specifically, a U-shaped frame 9 is installed on the workbench 1; a baffle 10 is installed on the U-shaped frame 9; the baffle 10 is located above the needle roller 8, and a gap is left between its lower edge and the surface of the needle roller 8 to prevent the needle from passing through. The function of the baffle 10 is to prevent the needle from being thrown out under the action of centrifugal force.
[0042] Furthermore, a dust baffle is installed on one side of the workbench 1 located in the discharge chute 13.
[0043] The working principle of this utility model:
[0044] During operation, the first motor 4 and the second motor 15 are turned on. The second motor 15 rotates, transmitting the rotation to the third rotating shaft 17 via a belt drive assembly or chain drive assembly, causing the grinding wheel 11 to rotate. The needle is placed into the inclined feed groove 12, and the needle slides along the feed groove 12 toward the needle-feeding wheel 8. The first motor 4 drives the first rotating shaft 5 to rotate, which in turn drives the pressure roller 6 to rotate. Because the needle-feeding wheel 8 presses against the pressure roller 6, the rotation of the pressure roller 6 drives the needle-feeding wheel 8 to rotate. The needle in the needle groove of the needle-feeding wheel 8 rotates with the needle-feeding wheel 8 until it enters between the pressure roller 6 and the base plate 2. The needle rotates and moves under the action of the pressure roller 6 and the base plate 2. During the movement of the needle, the grinding wheel 11 grinds the part of the needle that extends out of the base plate 2. After grinding, the needle slides down the inclined surface 202 of the base plate 2 into the discharge groove 13.
[0045] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
