Description
Technical Field
[0001] The utility model belongs to the technical field of pencil production equipment, and in particular relates to a feeding device for a paper-clamped pen core. Background Art
[0002] A pencil is a type of pen used for writing and drawing sketches. Traditional pencils are made of graphite and a wooden core rod. A paper clip pen is a type of disposable pencil, including a plastic shell and a pencil lead. The assembly process of the paper clip pen is to insert the pencil lead into the plastic shell. The pencil lead feeding device in the existing assembly equipment generally transfers the pencil lead to a feeding hole of a feeding seat, and uses the shape of the feeding hole to match the tip of the pencil lead, thereby fixing and restricting the pencil lead. Then the inner wall of the feeding hole applies a thrust to the tip of the pencil lead, thereby inserting the pencil lead into the plastic shell.
[0003] However, since the angle of the tip of each pencil lead is different, for example, it can be 15 to 30 degrees or even larger, the shape of the feeding hole is difficult to match the tip of the pencil lead, resulting in shaking of the pencil lead, thereby affecting the alignment accuracy of the subsequent insertion of the pencil lead into the plastic shell, resulting in installation failure.

[0033] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
[0034] like Figure 6 As shown, the paper-clamp pen 6 comprises a pen core 61 and a pen holder 62 which are plugged into each other, and an elastic clip 621 is installed on the pen holder 62; the pen core 61 comprises a core tip 611 and a core holder 612.
[0035] like Figures 1 to 4 As shown, a feeding device for a paper-clamped pen refill in one embodiment of the utility model comprises a frame 1, a feeding mechanism 2 and a positioning mechanism 3 mounted on the frame 1; a feeding cavity 21 is provided in the feeding mechanism 2, and a discharge port 22 connected to the feeding cavity 21 is provided at the lower end of the feeding mechanism 2; the positioning mechanism 3 comprises a positioning seat 31 and a positioning member 32 mounted on the positioning seat 31, a receiving cavity 311 is provided in the positioning seat 31, and an elastic abutment member 33 is provided on the bottom wall of the receiving cavity 311, and an elastic abutment member 33 is provided on the positioning member 32 A positioning hole 321 matching the core rod 612 is provided, and the positioning hole 321 has an axially arranged first opening 322 and a second opening 323, and the first opening 322 faces the elastic abutment 33 and is connected to the accommodating cavity 311; in the first state, the positioning member 32 is spaced below the feeding mechanism 2, and the second opening 323 is located below the discharge port 22 and aligned with the discharge port 22; the core tip 611 is abutted against the elastic abutment 33, and at least a part of the core rod 612 is located and inserted in the positioning hole 321.
[0036] It should be noted that when the pen core 61 is removed from the discharge port 22, the core tip 611 faces downward or toward the second opening 323, and then the entire pen core 61 enters the positioning hole 321 from the second opening 323 under the action of gravity or other forces, and the core tip 611 extends from the first opening 322 and abuts against the elastic abutment 33. The elastic abutment 33 can be made of existing elastic materials, such as rubber, etc. When the pen core 61 and the pen holder 62 are plugged in, the elastic abutment 33 can give the core tip 611 a supporting force, so that the core holder 612 can be plugged in with the pen holder 62, and reduce the degree of loss of the core tip 611 during the plugging process of the pen core 61 and the pen holder 62.
[0037] It can be understood that in the first state, the elastic abutment 33 abuts against the core tip 611, and the positioning hole 321 and the core rod 612 are inserted and cooperated, so as to limit the position of the pen core 61 and fix the pen core 61 during the loading process of the pen core 61, thereby ensuring the positioning of the pen core 61 and the stable loading process during the subsequent installation of the pen core 61 and the pen rod 62. Among them, the matching of the positioning hole 321 and the core rod 612 means that the size of the positioning hole 321 is slightly larger than the size of the core rod 612. For example, when the diameter of the core rod 612 is 2mm, the aperture of the positioning hole 321 can be about 2.1mm, that is, it can be considered that the size of the positioning hole 321 is slightly larger than the size of the core rod 612. Figures 1 to 4 All are views in the first state.
[0038] Preferably, the positioning member 32 is slidably connected to the accommodating cavity 311; in the first state, the top of the positioning member 32 protrudes out of the accommodating cavity 311 of the positioning seat 31. This arrangement is so that when the pen core 61 needs to be inserted into the pen holder 62, the positioning member 32 is pushed by other components or manually to move it into the accommodating cavity 311. Since the pen core 61 abuts against the elastic abutment member 33, the pen core 61 will not move or will only move slightly, that is, the positioning member 32 and the pen core 61 move relatively, until the pen core 61 extends out of the positioning hole 321 of the positioning member 32 from the second outlet, thereby facilitating the subsequent insertion process of the pen core 61 and the pen holder 62.
[0039] Furthermore, an elastic member 34 is installed in the accommodating cavity 311 of the positioning seat 31. Along the sliding direction of the positioning member 32, the elastic member 34 abuts against the positioning member 32 to drive the positioning member 32 to protrude out of the accommodating cavity 311 of the positioning seat 31. The elastic member 34 drives the positioning member 32 to protrude out of the accommodating cavity 311 of the positioning seat 31 in order to prevent the core rod 612 of the pen core 61 from protruding out of the positioning member 32, so that the positioning member 32 can play a role in positioning the pen core 61 and can also play a role in protecting the pen core 61.
[0040] Specifically, the elastic member 34 is a spring, and is sleeved on the elastic abutment member 33. The elastic abutment member 33 can play the role of limiting the spring. The spring can be considered as a compression spring.
[0041] Furthermore, the positioning member 32 is provided with a limiting portion 324, which is located in the accommodating cavity 311; in the first state, along the sliding direction of the positioning member 32, the limiting portion 324 is located in the accommodating cavity 311 and abuts against the inner wall of the accommodating cavity 311. In the first state, the limiting portion 324 plays a role in limiting the positioning member 32 from moving out of the accommodating cavity 311, that is, under the joint action of the elastic member 34 and the limiting portion 324, the relative position relationship between the positioning member 32 and the positioning seat 31 is limited.
[0042] like Figure 3 As shown, a guide surface 326 is provided at the second opening 323 . The guide surface 326 serves to guide the pen core 61 to enter the positioning hole 321 from the second opening 323 better.
[0043] In this embodiment, the feeding device further includes a blowing mechanism 4, and an air inlet 312 communicating with the outside is provided on the inner wall of the accommodating chamber 311, and the air inlet 312 is communicated with the blowing mechanism 4. Since the pen core 61 is generally made of graphite, it is easy to generate debris during the feeding process. The blowing mechanism 4 can be connected to an external air source (a clean, dust-free air source, such as air, etc.), and the blowing mechanism 4 can blow air into the accommodating chamber 311 through the air inlet 312, which can not only blow away the debris between the pen core 61 and the positioning port and the debris falling on the elastic abutment 33, but also make the accommodating chamber 311 produce a positive pressure state, which plays a role in assisting the pen core 61 to move out of the positioning hole 321 during the insertion process of the pen core 61 and the pen shaft 62.
[0044] Furthermore, a connecting hole 325 can be provided on the positioning member 32, and the connecting hole 325 is connected to the accommodating cavity 311, and the connecting hole 325 is connected to the first opening 322. The aperture of the connecting hole 325 is larger than the aperture of the positioning hole 321, and in the first state, the top of the elastic abutment 33 is located in the connecting hole 325. This arrangement is to facilitate the blowing mechanism 4 to blow away the debris that falls on the elastic abutment 33.
[0045] like Figure 1 , Figure 2 and Figure 4 As shown, the feeding device further includes a driving mechanism 5, which includes a first driver 51 mounted on the frame 1, and a movable member 52 mounted on the output end of the first driver 51, the movable member 52 is rotatably connected to the positioning seat 31, and the positioning seat 31 is movably connected to the frame 1; in the second state (such as Figure 5The second opening 323 is away from the discharge port 22 and is aligned with the pen shaft 62 of the paper clamp pen 6; wherein the first driver 51 is used to drive the movable member 52 to reciprocate so that the feeding device switches between the first state and the second state.
[0046] It can be understood that the first state is to make the pen core 61 fall from the feeding chamber 21 onto the positioning mechanism 3 and be fixed or limited by the positioning mechanism 3. Figure 1 , Figure 2 and Figure 4 As shown, the first driver 51 can be a cylinder, whose piston rod is connected to the movable member 52. The first driver 51 can drive the movable member 52 to perform linear motion. Since the movable member 52 is rotatably connected to the positioning seat 31, and the positioning seat 31 is movably connected to the frame 1, under the limitation of the connection relationship between the frame 1 and the movable member 52 and the positioning seat 31 respectively, when the movable member 52 pushes the positioning mechanism 3 to perform linear motion, it will also perform rotational motion relative to the movable member 52, that is, the driving mechanism 5 can drive the positioning mechanism 3 to be converted from the first state to the second state (such as Figure 5 similarly, the driving mechanism 5 can drive the positioning mechanism 3 to be converted from the second state to the first state.
[0047] Furthermore, the movable member 52 may have a limiting surface 521, in the second state (such as Figure 5 In the state shown), the positioning seat 31 abuts against the limiting surface 521, thereby limiting the position and placement angle of the positioning mechanism 3 in the second state, that is, limiting the direction of the second opening 323 of the positioning hole 321, so that the second opening 323 can be oriented towards the pen shaft 62.
[0048] Specifically, the frame 1 is provided with a slide groove 11, in which a pulley 12 is slidably connected, and the pulley 12 is rotatably connected to the positioning seat 31. This arrangement is to cooperate with the driving mechanism 5 to drive the positioning mechanism 3 to switch between the first state and the second state.
[0049] like Figure 4 As shown, the feeding mechanism 2 includes a locking assembly 23, which includes a second driver 231 and a locking tongue 232. The second driver 231 is used to drive the locking tongue 232 to insert into the feeding cavity 21 to prevent the pen core 61 from moving out of the discharge port 22. The locking tongue 232 can be supported by an elastic material, such as rubber, etc., to prevent the locking tongue 232 from damaging the pen core 61 when inserted into the feeding cavity 21.
[0050] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
