DETAILED DESCRIPTION
[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] The following is a combination of specific implementation cases and attached Figure 1-8 The present invention is further described below, but the present invention is not limited to these embodiments.
[0033] A writing pen automatic core loading device includes a base 7 fixed to a placement surface. The base 7 is fixed to the placement surface by bolts, and two brackets 5 are vertically fixed to the upper surface of the base 7 in parallel with each other. A core feeding assembly is arranged above the base 7. The core feeding box 2 of the core feeding assembly is fixedly embedded and installed between the two brackets 5, and the core feeding box 2 is fixed above the base 7 by the brackets 5 on both sides. A core placing box 1 is arranged at the feed inlet at the top of the core feeding assembly, and the inner cavity of the core placing box 1 is provided with a conveying assembly for sequentially inputting the pen cores. The pen cores are placed in the interior of the core placing box 1, and the pen cores are sequentially entered into the interior of the core feeding box 2 of the core feeding assembly through the internal conveying assembly. The pen cores fall onto the core feeding frame 3 through the outlet at the bottom of the core feeding box 2, and each pen core is sequentially delivered to the core loading seat 4 through a plurality of card slots 10 on the core feeding frame 3.
[0034] A core feeding frame 3 for conveying the pen core is rotatably arranged below the core feeding assembly, and a core loading assembly is arranged between the core feeding frame 3 and the base 7. A movable pen holder support 6 is arranged on the base 7, and the pen holder support 6 corresponds to the core loading assembly. The pen holder on the pen holder support 6 is moved to a position opposite to the core loading assembly on the upper surface of the base 7. Then, the pen core is loaded into the interior of the pen holder through the core loading assembly, which makes the processing of the writing pen production process more convenient, thereby improving the production efficiency of the writing pen. During the pen core conveying process, the pen core is conveyed to the core loading assembly in sequence through the core feeding frame 3. Then, each pen core is loaded into the pen holder in sequence to avoid accumulation of the pen core assembly process, thereby ensuring the smoothness of the core loading process.
[0035] Among them, the outer wall of the core feeding frame 3 is provided with a card slot 10 in a circumferential direction in sequence, and the outer circumference of the core feeding frame 3 is provided with a semicircular baffle 15 fixed on the base 7. The semicircular baffle 15 is a semicircular arc plate, and the two arc-shaped semicircular baffles 15 are fixedly connected, and the two semicircular baffles 15 are respectively circumferentially sleeved on the outside of the two core feeding frames 3. The two core feeding frames 3 are both disc-shaped, and a circle of card slots 10 are continuously opened in sequence on the outer wall of each circular core feeding frame 3, and the slots of the card slots 10 correspond to the specifications of the pen core. Through the semicircular baffle 15 on the outside of the core feeding frame 3, the pen core that falls inside the card slot 10 of the core feeding frame 3 slides along the inner wall of the semicircular baffle 15 as the core feeding frame 3 rotates. The semicircular baffle 15 limits the conveyed pen core to prevent the pen core from escaping from the inside of the card slot 10.
[0036] One end of the support rod 31 is fixedly mounted on the outer wall of the semicircular baffle 15, and the other end of the support rod 31 is vertically fixed to the upper surface of the base 7. One end of the rotating shaft 13 is vertically fixedly mounted on both sides of the frame body composed of the two core feeding frames 3, and bearings are embedded and installed on the opposite surfaces of the two brackets 5. The other ends of the rotating shaft 13 on both sides of the core feeding frame 3 are respectively embedded and installed inside the two bearings. The core feeding frame 3 rotates between the two brackets 5. The first drive motor 14 is fixed on the surface of one of the brackets 5 through the motor seat, and the output shaft of the first drive motor 14 passes through the inner cavity of the bracket 5 and extends to the inside and is fixedly connected to one end of the rotating shaft 13. The first drive motor 14 is electrically connected to the external power supply through a wire.
[0037] When assembling and conveying the pen core, the first drive motor 14 is connected to a power source so that the output shaft of the first drive motor 14 drives the corresponding rotating shaft 13 to rotate, so that the rotating shaft 13 drives the core feeding frame 3 to rotate between the two brackets 5. The pen core dropped from the core feeding box 2 falls on the card slot 10 on the outer wall of the core feeding frame 3, and as the core feeding frame 3 rotates, the pen core slides against the inner wall of the semicircular baffle 15. After the core feeding frame 3 rotates half a circle, the pen core slides out of the inner wall of the semicircular baffle 15 and falls onto the core loading seat 4. Then, the pen core is loaded into the inside of the pen holder on the pen holder support 6 through the core loading assembly. The operation of the pen core assembly process is made more convenient, and the pen cores are assembled one by one, thereby ensuring the smoothness of the writing pen processing process.
[0038] It is worth mentioning that the core loading assembly includes a core loading seat 4 fixed to the top of the base 7, and a limiting slide groove 16 is provided on the top of the core loading seat 4. The core loading seat 4 is fixed to the upper surface of the base 7 and is located at the bottom discharge position of the core feeding frame 3. A limiting slide groove 16 that penetrates the inner cavity is provided horizontally on the surface of the core loading seat 4. The limiting slide groove 16 is composed of two connected grooves, and the groove part located on the surface of the core loading seat 4 is a large semicircular groove larger than the specification of the pen core. A small semicircular groove corresponding to the specification of the pen core is provided below the large semicircular groove, and the two groove cavities are connected. Through the large semicircular groove with a large opening, the pen core falls into the small semicircular groove with a small space, and the sliding process of the pen core loading is limited by the small semicircular groove with a small space.
[0039] A push assembly for assembling the refill is provided on the side of the core loading seat 4 away from the pen holder support 6, and the push assembly corresponds to the limiting slide groove 16. A through hole 22 penetrating the inner cavity is provided on the surface of the bracket 5 between the pen holder support 6 and the core loading seat 4, and the through hole 22 is located on the straight line track where the core loading seat 4 and the pen holder support 6 are connected, and the aperture of the through hole 22 is larger than the specification of the refill. In the process of assembling the refill, the pen holder on the pen holder support 6 is moved to a position relative to the limiting slide groove 16 on the core loading seat 4. Then, the refill that falls into the limiting slide groove 16 is pushed by the push assembly, so that the refill slides against the inner wall of the limiting slide groove 16 and passes through the through hole 22 and is installed into the pen holder. After that, the next pen holder is moved to the relative position again by the pen holder support 6, and the next refill is installed continuously, so that the refills of the writing pen are installed in sequence, thereby ensuring the production efficiency of the writing pen.
[0040] In addition, the pushing assembly includes a movable seat 27 rotatably arranged on the side of the core-loading seat 4 away from the pen holder 6, and the inner cavity of the movable seat 27 is threadedly connected with a lead screw 21 opposite to the limiting slide groove 16. A movable hole penetrating the inner cavity is provided on the surface of the bracket 5 on the side of the core-loading seat 4 away from the pen holder 6, and a bearing is embedded and installed inside the movable hole. The movable seat 27 is embedded and installed inside the bearing, so that the movable seat 27 rotates inside the bracket 5 and both sides extend outside the two sides of the bracket 5. An internal thread penetrating the inner cavity is provided on the surface of the movable seat 27, and the position of the movable seat 27 ensures that the lead screw 21 connected with the internal thread can move to the inside of the limiting slide groove 16.
[0041] A first gear 29 is rotatably provided on the base 7, and a second gear 28 is sleeved on the outside of the movable base 27, and the second gear 28 meshes with the first gear 29. A second drive motor 30 is fixed to the upper surface of the base 7 through a motor seat, and the second drive motor 30 is a motor with forward and reverse functions, and the second drive motor 30 is electrically connected to an external power supply through a wire. The first gear 29 is fixedly sleeved on the outside of the output shaft of the second drive motor 30 through a central mounting hole, and the second gear 28 is fixedly sleeved on the outside of the movable base 27 through a central mounting hole.
[0042] After the pen core falls into the limiting slide groove 16, the second drive motor 30 is connected to the power supply. The output shaft of the second drive motor 30 drives the movable seat 27 to rotate inside the bracket 5, so that the lead screw 21 connected to the inner thread of the movable seat 27 moves horizontally. The lead screw 21 drives the circular push plate 32 fixedly installed at the end to move to the inside of the limiting slide groove 16, so that the circular push plate 32 slides against the inner wall of the limiting slide groove 16 and pushes the pen core to move from the limiting slide groove 16 to the outside. The pen core passes through the through hole 22 and enters the inside of the pen holder, making the operation process more convenient. The accuracy of the pen core assembly is guaranteed, thereby ensuring the quality of the writing pen.
[0043] In addition, the pen holder 6 is slidably arranged on the top of the base 7 through a guide rail 17. The guide rail 17 can be an electric guide rail. The guide rail base of the guide rail 17 is fixed on the upper surface of the base 7, and the slider of the guide rail 17 is fixed on the bottom of the pen holder 6. The pen holder 6 slides on the base 7 through the guide rail 17. Positioning grooves 18 for placing the pen holder are opened in sequence on the top of the pen holder 6. A non-through positioning groove 18 is opened from the surface of the pen holder 6 relative to the core mounting seat 4. The cross-sectional shape of the positioning groove 18 is mostly semicircular, that is, the shape of the longitudinal cross-section is larger than a semicircle. The positioning groove 18 is used to limit the top of the pen holder to prevent the pen holder from sliding out of the positioning groove 18. The pen holder 6 is continuously moved by the guide rail 17, so that the pen cores are assembled in sequence, thereby ensuring the efficiency of the writing pen processing process.
[0044] Furthermore, the core delivery assembly includes a core delivery box 2, and a core drop hole 20 penetrating the inner cavity is provided on the top of the core delivery box 2. The two sides of the core delivery box 2 are respectively fixed to the opposite surfaces of the two brackets 5 and fixed by bolts, and the upper surface of the core delivery box 2 is longitudinally provided with a core drop hole 20 penetrating the inner cavity. The aperture of the core drop hole 20 corresponds to the specification of the pen core, so that the pen core sequentially enters the interior of the core drop hole 20 from the upper surface of the core delivery box 2, and is discharged to the outside through the bottom of the core drop hole 20. The aperture of the core drop hole 20 allows only one pen core to enter at a time.
[0045] Limit baffles 12 are provided on both sides of the bottom outlet of the core drop hole 20. The two limit baffles 12 are vertically fixed on both sides of the bottom outlet of the core drop hole 20 in parallel with each other. The pen core is guided to fall by the limit baffles 12 on both sides, so that the pen core falls on the card slot 10 of the core feeding frame 3. After that, the core installation process is carried out, and two side baffles 11 are fixedly installed in parallel with each other at the bottom of the core feeding box 2. The two side baffles 11 and the limit baffles 12 are arranged perpendicular to each other and are located on both sides of the core feeding frame 3. The two side baffles 11 limit the two ends of the pen core to prevent it from detaching from the core feeding frame 3, and limit the falling pen core in four directions. The pen core is accurately placed on the core feeding frame 3, thereby ensuring the stability of the pen core transportation and installation process.
[0046] The conveying assembly includes a center roller 26 rotatably arranged in the inner cavity of the core placing box 1. Bearings are embedded and installed in the inner walls on both sides of the core placing box 1, and the two ends of the central axis of the center roller 26 are respectively embedded and installed in the inside of the two bearings, so that the center roller 26 rotates inside the core placing box 1. A discharge port is opened on the upper surface of the core placing box 1, and a feed plate 8 is circumferentially arranged on the outer wall of the center roller 26. Multiple feed plates 8 are fixedly installed on the outer wall of the center roller 26 in sequence in the circumferential direction.
[0047] The third drive motor 19 is fixed to one side of the core placing box 1 through a motor seat, and the third drive motor 19 is electrically connected to an external power source through a wire. The output shaft of the third drive motor 19 penetrates the side wall of the core placing box 1 and extends to the inner end corresponding to the center roller 26 and is fixedly connected, so that multiple circumferential conveying plates 8 rotate along with the center roller 26 in contact with the inner wall of the core placing box 1. The rotation speed of the conveying plates 8 is adjusted by the third drive motor 19, and the refill is driven to move inside the core placing box 1 by low-speed rotation, so that the refills are assembled and installed in sequence.
[0048] A connection box 9 is fixedly installed between the bottom of the core placing box 1 and the top of the core sending box 2, and a through hole 24 penetrating the inner cavity is provided on the surface of the connection box 9. The core placing box 1 is connected to the inside of the core sending box 2, and the aperture of the through hole 24 corresponds to the lead, which ensures the stability of the lead conveying process.
[0049] When the writing pen is loaded with a core, the third drive motor 19 is connected to a power source. The output shaft of the third drive motor 19 drives the center roller 26 to rotate inside the core placing box 1, and the center roller 26 drives the circumferential multiple conveying plates 8 to slide against the inner wall of the core placing box 1. The multiple slowly rotating conveying plates 8 sequentially convey the pen core to the discharge hole 25 at the bottom of the core placing box 1, and the pen core enters the perforation 24 of the connecting box 9 through the discharge hole 25. After passing through the perforation 24, the pen core enters the inside of the core feeding box 2, making the pen core assembly and loading process smoother and avoiding accumulation, thereby ensuring the efficiency of the pen core assembly process.
[0050] The present embodiment is an automatic core loading device for writing pens, and its working principle is as follows: when processing the core loading of the writing pen, the core is placed inside the core placing box 1. Then the third driving motor 19 is connected to the power supply, so that the output shaft of the third driving motor 19 drives the center roller 26 to rotate inside the core placing box 1, so that the center roller 26 drives multiple circumferential conveying plates 8 to slide against the inner wall of the core placing box 1. The core is sequentially transported to the discharge hole 25 at the bottom of the core placing box 1 by the multiple slowly rotating conveying plates 8, and the core enters the perforation 24 of the connecting box 9 through the discharge hole 25, and then enters the inside of the core delivery box 2 after passing through the perforation 24.
[0051] The pen refills sequentially enter the interior of the core drop hole 20 from the upper surface of the core delivery box 2, and are discharged to the outside through the bottom of the core drop hole 20. Then the pen refills fall into the slot 10 on the core delivery frame 3. Then the first drive motor 14 is connected to the power supply, so that the output shaft of the first drive motor 14 drives a corresponding shaft 13 to rotate, so that the shaft 13 drives the core delivery frame 3 to rotate between the two brackets 5. The pen refills dropped from the core delivery box 2 fall into the slot 10 on the outer wall of the core delivery frame 3, and as the core delivery frame 3 rotates, the pen refills slide against the inner wall of the semicircular baffle 15. After the core delivery frame 3 rotates half a circle, the pen refills slide out of the inner wall of the semicircular baffle 15 and fall into the core loading seat 4.
[0052] Then, the second drive motor 30 is connected to a power source, so that the output shaft of the second drive motor 30 drives the movable seat 27 to rotate inside the bracket 5. The screw 21 connected to the inner thread of the movable seat 27 moves horizontally, so that the screw 21 drives the circular push plate 32 fixedly installed at the end to move to the inside of the limiting slide groove 16. The circular push plate 32 slides against the inner wall of the limiting slide groove 16 and pushes the pen core to move from the limiting slide groove 16 to the outside, so that the pen core passes through the through hole 22 and enters the inside of the pen holder.
