Description

Technical Field

[0001] This invention relates to the field of pencil lead packaging equipment technology, specifically to a pencil lead counting and measuring device. Background Technology

[0002] In the 15th century, graphite mines were discovered. People at the time did not know the composition of graphite, so they called it black lead. Around 1492, people in England began to use pens made of graphite, which were then called pencils.

[0003] It wasn't until 1779 that scientists realized graphite was a form of carbon. Graphite is ground into powder, mixed with clay, and then poured into two semi-circular wooden tubes to create the pen. Plastic pen barrels are also available.

[0004] In the pencil lead production process, after the lead leads are fired and shaped, they need to be boxed and packaged. Currently, the packaging method used in the industry is manual weighing and manual packing, which requires a lot of physical strength from the operators. In addition, during the filling process, manual counting is prone to errors in the filling quantity. Therefore, there is a need to provide a pencil lead counting and measuring device to solve the above problems. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a pencil lead counting device to solve the problems mentioned in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A pencil lead counting and measuring device, comprising:

[0008] Pen refill packaging machine;

[0009] The feeding unit, installed inside the pencil lead packaging machine, is used to feed pencil leads.

[0010] The metering unit is connected to the feeding unit and is used to measure the feeding unit.

[0011] The positioning unit is installed on the pen refill packaging machine and connected to the feeding unit to position the feeding unit.

[0012] The drive unit is installed on the pen refill packaging machine and connected to the feeding unit. It is used to drive the feeding unit to rotate in a specific direction.

[0013] The feeding unit, installed on the pen refill packaging machine, is used to feed the pen refill boxes;

[0014] The material handling unit is connected to the box feeding unit and is used to guide and limit the box feeding unit.

[0015] Compared with the prior art, the embodiments of the present invention have the following beneficial effects: The present invention includes a feeding unit installed inside a pencil lead packaging machine for feeding pencil leads; a metering unit connected to the feeding unit for metering the feeding unit; a positioning unit installed on the pencil lead packaging machine and connected to the feeding unit for positioning the feeding unit; a driving unit installed on the pencil lead packaging machine and connected to the feeding unit for driving the feeding unit to rotate in a specific direction; and a box feeding unit installed on the pencil lead packaging machine for feeding pencil lead boxes.

[0016] During pencil lead filling, the pencil leads are introduced into the feeding unit, and the drive unit is activated. The drive unit, connected to the feeding unit, drives the metering unit to rotate intermittently. This allows the metering unit to automatically count and measure the pencil leads in the feeding unit during the filling process, effectively improving the efficiency and accuracy of pencil lead counting.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0027] See Figures 1-6 A pencil lead counting and measuring device, comprising:

[0028] Pen refill packaging machine 1;

[0029] The feeding unit 2 is installed inside the pencil lead packaging machine 1 and is used to feed pencil leads.

[0030] Metering unit 3 is connected to feeding unit 2 and is used to meter feeding unit 2;

[0031] Positioning unit 4 is installed on pen refill packaging machine 1 and connected to feeding unit 2, and is used to position feeding unit 2;

[0032] The drive unit 5 is installed on the pen refill packaging machine 1 and connected to the feeding unit 2, and is used to drive the feeding unit 2 to rotate in a specific direction.

[0033] The feeding unit 6 is installed on the pen refill packaging machine 1 and is used to feed the pen refill boxes;

[0034] The material handling unit 7 is connected to the feeding unit 6 and is used to guide and limit the feeding unit 6.

[0035] In an embodiment of the present invention, when filling pencil leads, the pencil leads are introduced into the feeding unit 2, and the drive unit 5 is activated. The drive unit 5, connected to the feeding unit 2, drives the metering unit 3 to rotate intermittently, so that the metering unit 3 can automatically count and measure the pencil leads in the feeding unit 2 during the pencil lead feeding process. The lead box is placed in the feeding unit 6, and the feeding unit 6 is activated. The feeding unit 6, driven by the picking unit 7, causes the lead box to slide out intermittently, facilitating the picking of the lead box for filling the pencil leads after the lead box has been counted and measured by the feeding unit 2.

[0036] In one embodiment of the present invention, such as Figure 2 and Figure 5 As shown, the feeding unit 2 includes:

[0037] The feed hopper 21 is installed on the pen refill packaging machine 1, and a rotating rod 22 is rotatably connected inside it.

[0038] The feed cylinder 23 is installed at the end of the rotating rod 22, and has an opening 231 on its surface;

[0039] The transmission rod 24 is rotatably connected inside the pen refill packaging machine 1, and a rotating disk 25 is mounted on its surface.

[0040] The placement groove 251 is formed on the surface of the rotating disk 25 and is used to drive the pencil lead for transmission.

[0041] In this embodiment, the feeding hopper 21 is installed on the pencil lead packaging machine 1, and a rotating rod 22 is rotatably connected inside it; the feeding cylinder 23 is installed at the end of the rotating rod 22, and an opening 231 is provided on its surface; the transmission rod 24 is rotatably connected inside the pencil lead packaging machine 1, and a rotating disk 25 is installed on its surface; the placement groove 251 is opened on the surface of the rotating disk 25 and is used to drive the pencil lead to perform transmission.

[0042] When filling pencil leads, the pencil leads are introduced into the feeding hopper 21, and the drive unit 5 is activated. The drive unit 5 can rotate the feeding cylinder 23 on its surface via the rotating rod 22. When the feeding cylinder 23 rotates the opening 231 to the upper side, the pencil leads in the feeding hopper 21 can flow into the feeding cylinder 23 through the opening 231. When the feeding cylinder 23 continues to rotate the opening 231 to the lower side, the pencil leads in the feeding cylinder 23 can slide out through the opening 231. When the rotating rod 22 rotates, it can drive the transmission rod 24 to rotate within the pencil lead packaging machine 1 through its connection with the metering unit 3. Thus, the transmission rod 24 can drive the placement groove 251 to rotate intermittently via the rotating disk 25, causing the placement groove 251 and the opening 231 to overlap, so that the pencil leads in the feeding cylinder 23 can slide into the placement groove 251 through the opening 231.

[0043] The above working process is repeated in sequence. When the feed cylinder 23 drives the opening 231 to rotate upward again, the pencil lead in the feed hopper 21 can slide back into the feed cylinder 23, so that the pencil lead can be fed intermittently.

[0044] The placement slots 251 in the feeding unit 2 are provided in eight or ten groups, which is not limited to one group here.

[0045] In one embodiment of the present invention, such as Figure 2 As shown, the metering unit 3 includes:

[0046] A rotating column 31 is mounted on the surface of a rotating disk 25;

[0047] The rotating frame 32 is connected to the surface of the rotating rod 22 and is slidably connected to the rotating column 31;

[0048] The first sensor 33 is installed inside the pen refill packaging machine 1;

[0049] The second sensor 34 is mounted on the surface of the rotating disk 25 and is rotatably connected to the first sensor 33.

[0050] In this embodiment, the rotating column 31 is mounted on the surface of the rotating disk 25; the rotating frame 32 is connected to the surface of the rotating rod 22 and is slidably connected to the rotating column 31; the first sensor 33 is mounted inside the pen refill packaging machine 1; the second sensor 34 is mounted on the surface of the rotating disk 25 and is rotatably connected to the first sensor 33. A display screen is mounted on the side of the pen refill packaging machine 1, and a controller is installed inside the pen refill packaging machine 1. The controller is electrically connected to the display screen, the first sensor 33, and the second sensor 34 respectively.

[0051] When the rotating rod 22 rotates, it can drive the rotating frame 32 to rotate synchronously. When the rotating frame 32 rotates to contact the rotating column 31, the rotating column 31 can be pushed by the rotating frame 32 to make the rotating disk 25 drive the transmission rod 24 to rotate in the pencil lead packaging machine 1 until the rotating frame 32 rotates to disengage from the surface of the rotating column 31. At this time, the rotating disk 25 can stop rotating. During the rotation of the rotating disk 25, it can drive the placement groove 251 to rotate below the opening 231, so that the pencil lead in the feed cylinder 23 can slide into the placement groove 251 through the opening 231.

[0052] During the rotation of the rotating disk 25, the second sensor 34 on its surface can rotate synchronously. When the second sensor 34 rotates to contact the first sensor 33, the controller in the pencil lead packaging machine 1 can control the display screen to count, thereby counting the number of rotations of the rotating disk 25. Since the placement groove 251 on the surface of the rotating disk 25 is fixed, the filling of pencil leads can be measured.

[0053] The surface of the rotating column 31 in the metering unit 3 can also be fitted with a rubber ring or rollers to protect the rotating column 31.

[0054] In one embodiment of the present invention, such as Figure 2 As shown, the positioning unit 4 includes:

[0055] Positioning disc 41 is mounted on rotating rod 22, and groove 42 is provided on its surface;

[0056] A connecting plate 43 is connected to the side of the rotating plate 25, and a positioning post 44 is mounted on its surface. The positioning post 44 and the surface of the positioning plate 41 are rotatably connected.

[0057] In this embodiment, the positioning disk 41 is mounted on the rotating rod 22, and a groove 42 is provided on its surface; the connecting disk 43 is connected to the side of the rotating disk 25, and a positioning post 44 is mounted on its surface, and the positioning post 44 and the surface of the positioning disk 41 are rotatably connected.

[0058] When the rotating disk 25 rotates, it can drive the connecting disk 43 on its side to rotate synchronously. The connecting disk 43 can drive the positioning pin 44 to rotate synchronously. When the rotating rod 22 rotates, it can drive the groove 42 to rotate synchronously through the positioning disk 41. When the rotating frame 32 rotates to the point of disengaging from the surface of the rotating pin 31, the positioning disk 41 can rotate on the surface of the positioning pin 44. Thus, the positioning disk 41 can limit the connecting disk 43 through the two sets of positioning pins 44, and in turn, the connecting disk 43 can limit the rotating disk 25, thereby improving the stability of the rotating disk 25 after intermittent rotation.

[0059] Until the rotating frame 32 rotates to contact the rotating column 31, the positioning plate 41 can drive the groove 42 to rotate to the side of the positioning column 44. Therefore, when the rotating column 31 drives the rotating plate 25 to rotate under the push of the rotating frame 32, the rotating plate 25 can drive the positioning column 44 to rotate in the groove 42 through the connecting plate 43, which prevents the positioning plate 41 from interfering with the overall rotation of the connecting plate 43 and the positioning column 44.

[0060] Rollers can also be installed on the surface of the positioning post 44 in the positioning unit 4, so that the positioning disk 41 can limit the connection disk 43 and the rotating disk 25 by means of the rollers and the positioning post 44.

[0061] In one embodiment of the present invention, such as Figure 3 As shown, the driving unit 5 includes:

[0062] Drive unit 51 is installed on pen refill packaging machine 1;

[0063] The rotating shaft 52 is rotatably connected to the pen refill packaging machine 1 and connected to the output end of the drive component 51;

[0064] The first gear 53 is mounted on the surface of the rotating shaft 52;

[0065] An arc-shaped frame 54 is installed on the inner wall of the pen refill packaging machine 1, and a sliding column 55 is slidably connected inside;

[0066] A sliding gear 56 is mounted on the surface of a sliding column 55, and the sliding gear 56 is meshed with the first gear 53.

[0067] The rotating rod 57 is rotatably connected inside the pen refill packaging machine 1, and a second gear 571 is mounted on its surface. The second gear 571 and the sliding gear 56 are meshed together.

[0068] The third gear 58 is mounted on the rotating rod 22 and meshes with the second gear 571.

[0069] In this embodiment, the drive component 51 is mounted on the pen refill packaging machine 1; the rotating shaft 52 is rotatably connected to the pen refill packaging machine 1 and connected to the output end of the drive component 51; the first gear 53 is mounted on the surface of the rotating shaft 52; the arc-shaped frame 54 is mounted on the inner wall of the pen refill packaging machine 1, and a sliding column 55 is slidably connected inside; the sliding gear 56 is mounted on the surface of the sliding column 55, and the sliding gear 56 and the first gear 53 are meshed together; the rotating rod 57 is rotatably connected inside the pen refill packaging machine 1, and a second gear 571 is mounted on its surface, and the second gear 571 and the sliding gear 56 are meshed together; the third gear 58 is mounted on the rotating rod 22 and is meshed together with the second gear 571.

[0070] When the drive unit 51 is activated, it can drive the first gear 53 to rotate via the rotating shaft 52. When the rotating shaft 52 drives the first gear 53 to rotate clockwise, the first gear 53, through its connection with the sliding gear 56, can drive the sliding column 55 to rotate counterclockwise within the arc frame 54. When the sliding gear 56 rotates, it can drive the rotating rod 57 to rotate clockwise within the pen refill packaging machine 1 through its connection with the second gear 571. When the second gear 571 rotates, it can drive the rotating rod 22 to rotate counterclockwise within the pen refill packaging machine 1 through its connection with the third gear 58. Thus, the rotating rod 22 can drive the feeding cylinder 23 to rotate counterclockwise within the pen refill packaging machine 1.

[0071] When the rotating shaft 52 drives the first gear 53 to rotate counterclockwise, the first gear 53, through its connection with the sliding gear 56, drives the sliding column 55 to slide upward within the arc frame 54 until the sliding column 55 slides to the uppermost end of the arc frame 54. At this point, the sliding column 55 drives the sliding gear 56 to slide until it contacts the third gear 58. When the sliding column 55 slides to the leftmost end of the arc frame 54, the sliding gear 56, under the action of the first gear 53, drives the sliding column 55 to rotate clockwise within the arc frame 54. Thus, the sliding gear 56, through its connection with the third gear 58, drives the rotating rod 22 to rotate counterclockwise within the pen refill packaging machine 1. Consequently, the rotating rod 22 drives the feeding cylinder 23 to rotate counterclockwise within the pen refill packaging machine 1.

[0072] Therefore, regardless of whether the rotating shaft 52 rotates clockwise or counterclockwise, the rotating rod 22 always drives the feeding cylinder 23 to rotate counterclockwise within the pencil lead packaging machine 1. This allows the feeding cylinder 23 to rotate in a specific direction, preventing the pencil lead in the placement groove 251 from breaking during the reverse rotation of the feeding cylinder 23 through the placement groove 251, thereby improving the protective performance of the pencil lead.

[0073] The driving component 51 can be a servo motor or a pneumatic motor, which can easily drive the rotating shaft 52 to rotate stably.

[0074] In one embodiment of the present invention, such as Figure 4 and Figure 6 As shown, the feeding unit 6 includes:

[0075] A feeding box 61 is installed inside the pen refill packaging machine 1, and a feeding trough 611 is provided at the bottom;

[0076] The placement rack 62 is fixed to the inner wall of the pen refill packaging machine 1;

[0077] An arc-shaped groove 63 is formed on the pen refill packaging machine 1, and a sliding column 67 is slidably connected inside it.

[0078] A sliding groove 64 is formed on the pen refill packaging machine 1, communicates with the arc-shaped groove 63, and is slidably connected to the sliding column 67;

[0079] Motor 65 is installed on pen refill packaging machine 1;

[0080] The rotating carriage 66 is connected to the output end of the motor 65 and is slidably connected to the slide column 67.

[0081] In this embodiment, the feeding box 61 is installed inside the pen refill packaging machine 1, and a feeding trough 611 is provided at the bottom; the placement rack 62 is fixed on the inner wall of the pen refill packaging machine 1; the arc-shaped groove 63 is opened on the pen refill packaging machine 1, and a sliding column 67 is slidably connected inside; the sliding groove 64 is opened on the pen refill packaging machine 1, communicates with the arc-shaped groove 63, and is slidably connected with the sliding column 67; the motor 65 is installed on the pen refill packaging machine 1; the rotating slide 66 is connected to the output end of the motor 65 and is slidably connected with the sliding column 67.

[0082] By placing the pencil lead box in the supply box 61 and turning on the motor 65, the output end of the motor 65 can drive the sliding column 67 to slide clockwise in the arc-shaped groove 63 via the rotating slide 66 until the sliding column 67 slides through the arc-shaped groove 63 to the left end of the sliding groove 64. The sliding column 67 can also slide within the rotating slide 66. When the rotating slide 66 continues to rotate, it can drive the sliding column 67 to slide horizontally to the right within the sliding groove 64. Thus, the sliding column 67 can slide the pencil lead box in the supply box 61 through the feeding chute 611 via the picking unit 7 until the pencil lead box slides onto the placement rack 62, making it easy to pick up the pencil lead box for filling with pencil lead.

[0083] The motor 65 in the feeding unit 6 can also be replaced by a handle, which can be used to drive the rotating carriage 66 to rotate stably.

[0084] In one embodiment of the present invention, such as Figure 4 As shown, the material handling unit 7 includes:

[0085] Guide groove 71 is formed on pen refill packaging machine 1;

[0086] Sliding member 72 is slidably connected within guide groove 71;

[0087] The slide rod 73 is rotatably connected to the surface of the slide column 67 and slidably connected within the slide member 72.

[0088] In this embodiment, the guide groove 71 is formed on the pen refill packaging machine 1; the sliding member 72 is slidably connected in the guide groove 71; the sliding rod 73 and the sliding column 67 are rotatably connected to each other and slidably connected in the sliding member 72.

[0089] During the sliding process of the sliding column 67 within the arc-shaped groove 63 and the sliding groove 64, the sliding column 67 can drive the sliding rod 73 to slide vertically within the sliding member 72. Furthermore, the sliding member 72 can slide within the guide groove 71 under the push of the sliding rod 73, allowing the guide groove 71 to guide and limit the sliding rod 73 via the sliding member 72. When the rotating carriage 66 drives the sliding column 67 to slide horizontally to the right within the sliding groove 64, the sliding column 67 can simultaneously drive the sliding member 72 to slide horizontally to the right within the guide groove 71 via the sliding rod 73. This allows the upper end of the sliding rod 73 to slide the pen refill box from the supply box 61 onto the placement rack 62 via the feeding groove 611.

[0090] By repeating the above process, the pen refill boxes in the supply box 61 can be slid out intermittently. A sliding frame can also be installed at the upper end of the slide rod 73 in the feeding unit 7, allowing the pen refill boxes in the supply box 61 to be slid out intermittently via the sliding frame.

[0091] The working principle of this invention is as follows: When filling pencil leads, the pencil leads are introduced into the feeding hopper 21, and the drive unit 5 is activated. The drive unit 5 can rotate the feeding cylinder 23 on its surface via the rotating rod 22. When the feeding cylinder 23 rotates the opening 231 to the upper side, the pencil leads in the feeding hopper 21 can flow into the feeding cylinder 23 through the opening 231. When the feeding cylinder 23 continues to rotate the opening 231 to the lower side, the pencil leads in the feeding cylinder 23 can slide out through the opening 231. When the rotating rod 22 rotates, it can drive the transmission rod 24 to rotate within the pencil lead packaging machine 1 through its connection with the metering unit 3. Thus, the transmission rod 24 can drive the placement groove 251 to rotate intermittently via the rotating disk 25, causing the placement groove 251 and the opening 231 to overlap, so that the pencil leads in the feeding cylinder 23 can slide into the placement groove 251 through the opening 231.

[0092] When the rotating rod 22 rotates, it can drive the rotating frame 32 to rotate synchronously. When the rotating frame 32 rotates to contact the rotating column 31, the rotating column 31 can be pushed by the rotating frame 32 to make the rotating disk 25 drive the transmission rod 24 to rotate in the pencil lead packaging machine 1 until the rotating frame 32 rotates to disengage from the surface of the rotating column 31. At this time, the rotating disk 25 can stop rotating. During the rotation of the rotating disk 25, it can drive the placement groove 251 to rotate below the opening 231, so that the pencil lead in the feed cylinder 23 can slide into the placement groove 251 through the opening 231.

[0093] During the rotation of the rotating disk 25, the second sensor 34 on its surface can rotate synchronously. When the second sensor 34 rotates to contact the first sensor 33, the controller in the pencil lead packaging machine 1 can control the display screen to count, thereby counting the number of rotations of the rotating disk 25. Since the placement groove 251 on the surface of the rotating disk 25 is fixed, the filling of pencil leads can be measured.

[0094] By placing the pencil lead box in the supply box 61 and turning on the motor 65, the output end of the motor 65 can drive the sliding column 67 to slide clockwise in the arc-shaped groove 63 via the rotating slide 66 until the sliding column 67 slides through the arc-shaped groove 63 to the left end of the sliding groove 64. The sliding column 67 can also slide within the rotating slide 66. When the rotating slide 66 continues to rotate, it can drive the sliding column 67 to slide horizontally to the right within the sliding groove 64. Thus, the sliding column 67 can slide the pencil lead box in the supply box 61 through the feeding chute 611 via the picking unit 7 until the pencil lead box slides onto the placement rack 62, making it easy to pick up the pencil lead box for filling with pencil lead.
