Description

Technical Field

[0001] This utility model relates to the field of pen refill processing, specifically a clamping and conveying device for pen refill processing. Background Technology

[0002] The clamping and conveying equipment for pen refill processing is a key piece of equipment on the pen refill production line for fixing and transferring pen refills. Its core function is to stably fix the pen refills through clamping mechanisms during the filling, assembly, and testing processes, and to accurately transfer the pen refills along a predetermined path using a conveying system, ensuring the continuity and accuracy of each processing step. In the automated production process of pen refills, due to the small diameter of the pen refill tubes, the fragility of the material, and the significant differences in the requirements for the posture and positional accuracy of the pen refills in different processes, it is necessary to rely on professional clamping and conveying equipment to prevent the pen refills from shifting, shaking, or being damaged during transmission, so as to ensure product quality and production efficiency.

[0003] Traditional pen refill clamping and conveying equipment mostly adopts a single transmission structure. A single transmission method is difficult to realize the multi-dimensional movement of the clamping mechanism, which means that the pen refill cannot adjust its posture according to different processing steps during the conveying process. In addition, the rigid clamping structure has poor adaptability to the pen refill diameter. When changing pen refills of different specifications, not only is it necessary to use tools to disassemble the clamping parts, which is time-consuming and laborious, but it is also easy to cause pen refill deformation due to excessive clamping or conveying deviation due to excessive clamping. To address this, we propose a clamping and conveying equipment for pen refill processing. Utility Model Content

[0006] Preferably, the inner walls of both sides of the limiting plate on the support are tangent to the outer arc surface of the base.

[0007] Preferably, the planetary gear set includes a first pinion, a second pinion, and a large gear. The large gear is rotatably connected to the base, and the output shaft of the motor inside the base is coaxially and fixedly connected to the large gear.

On the side of the base corresponding to the second pinion, multiple first pinions are also rotatably connected, and the first pinions are distributed in a ring at equal intervals. The first pinions mesh with the second pinions.

[0008] Preferably, a fixed base is coaxially fixedly mounted on the pinion, and another motor is fixedly connected to the bottom surface of the fixed base. Two sets of hinged seats are symmetrically fixedly mounted on the upper surface of the fixed base, and a threaded hole is provided in the middle of the upper surface of the fixed base. The hinge consists of two hinge blocks, one tall and one short, with the shorter hinge block installed in front of the taller hinge block.

[0009] Preferably, the clamping mechanism includes a sliding seat, a lead screw, and a connecting rod. The lead screw is rotatably connected to the threaded hole on the fixed base, and the sliding seat is threadedly connected to the support. A hinge seat is symmetrically fixedly installed on the outer arc surface of the sliding seat, and a connecting rod is hinged to each hinge seat on the sliding seat.

[0011] Preferably, two hinge blocks are installed on the bottom surface of the connecting block, the other end of the first connecting rod is hinged to one of the hinge blocks at the bottom of the connecting block, and the other end of the second connecting rod is hinged to the other hinge block at the bottom of the connecting block; A support plate is fixedly installed on the upper surface of the connecting block, and a surrounding plate is installed on three sides of the upper plane of the support plate. The support plate and the surrounding plate together constitute the connecting seat.

[0012] Preferably, the quick-change assembly includes a sliding block, a wedge block, and a spring. A spring is fixedly installed in the middle of the upper surface of the support plate on the connecting block.

[0014] Compared with the prior art, this utility model provides a clamping and conveying device for pen refill processing, which has the following beneficial effects: 1. This pen refill processing clamping and conveying equipment adopts a planetary gear turntable structure. The large gear is driven by a motor to rotate, which drives the two small gears, which are distributed at equal intervals in a ring, to mesh. This allows the clamping mechanism on the fixed base to achieve multi-directional position adjustment and angle rotation. Compared with the traditional single transmission method, this improves the flexibility of the pen refill during the conveying process and can meet the requirements of different processing steps for the pen refill posture.

[0015] 2. The clamping and conveying equipment for pen refill processing uses a clamping mechanism with a linkage design of a lead screw, connecting rod one, connecting rod two, and connecting rod three. When the lead screw rotates, it drives the sliding seat to move, and then the connecting block drives the V-groove module to achieve the clamping action through the linkage transmission. Compared with the traditional rigid clamping, this linkage transmission structure can provide a more stable clamping force and has better adaptability to pen refills of different diameters, reducing the damage to the pen refills during the clamping and conveying process.

[0016] 3. This pen refill processing clamping and conveying equipment uses a quick-change component that utilizes the cooperation of springs, wedge blocks, and sliding blocks. When it is necessary to replace the V-groove module, simply press the wedge block to compress the spring, causing the sliding block to move, which allows for quick disassembly and installation of the V-groove module. Compared with the traditional method that requires tools for disassembly, this greatly improves the replacement efficiency and shortens the equipment debugging time, making it especially suitable for the batch processing and production of pen refills of various specifications.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 A clamping and conveying device for pen refill processing includes a support 1, a motor 2, a pulley 3 and a conveyor belt 4. The pulley 3 is rotatably connected to the support 1, and the conveyor belt 4 is connected between the two pulleys 3. The motor 2 is fixedly installed on one outer wall of the support 1, and the output shaft of the motor 2 is coaxially fixedly connected to one of the pulleys 3. Limiting plates are symmetrically fixedly installed on the upper plane of support 1; The conveyor belt 4 is equipped with a planetary gear turntable, which includes a motor 2, a base 5, and a planetary gear set. The base 5 is fixedly installed on the plane of the conveyor belt 4, and another motor 2 is fixedly connected inside the base 5. The planetary gear set is installed on the base 5. The planetary gear turntable is equipped with a clamping mechanism, and the clamping mechanism is equipped with a quick-change component.

[0021] Furthermore, the inner walls of the limiting plate on both sides of the support 1 are tangent to the outer arc surface of the base 5. The mechanical limiting ensures that the base 5 maintains a stable trajectory when moving on the conveyor belt 4, avoiding positional deviation of the planetary wheel turntable and clamping mechanism due to offset.

[0022] Furthermore, the planetary gear set includes a first pinion 6, a second pinion 7, and a large gear 8. The large gear 8 is rotatably connected to the base 5, and the output shaft of the motor 2 inside the base 5 is coaxially and fixedly connected to the large gear 8. Multiple second pinions 7 are rotatably connected to the base 5. The second pinions 7 are distributed in a ring at equal intervals, and the second pinions 7 are meshed with the large gear 8.

[0023] Furthermore, a fixed base 9 is coaxially fixedly mounted on the pinion 6, another motor 2 is fixedly connected to the bottom surface of the fixed base 9, and two sets of hinged seats are symmetrically fixedly mounted on the upper surface of the fixed base 9. A threaded hole is opened in the middle of the upper surface of the fixed base 9. The hinge consists of two hinge blocks, one high and one low. The lower hinge block is installed in front of the higher hinge block. The two sets of hinge seats, one high and one low, on the fixed base 9 provide hinge fulcrums of different heights for connecting rod 12 and connecting rod 23. The height difference forms a lever transmission structure, which enables the connecting rod assembly to generate a stable clamping force during the clamping process.

[0024] Furthermore, the clamping mechanism includes a sliding seat 10, a lead screw 11, and a connecting rod 14. The lead screw 11 is rotatably connected to the threaded hole on the fixed base 9, and the sliding seat 10 is threadedly connected to the support 1.

Connecting rod 12 is hinged to the higher hinge block on the fixed base 9, and connecting rod 23 is hinged to the lower hinge block on the fixed base 9. Link 2 13 is a bent link with an obtuse angle. When the sliding seat 10 moves, the obtuse angle structure can decompose the thrust of link 3 14 into a clamping force perpendicular to the connecting block 15 and a stabilizing force in the horizontal direction. This can ensure the clamping effect of the V-groove module 16 on the pen refill, and reduce the deformation of the link assembly through structural mechanics design, thereby improving the durability of the clamping mechanism. The other end of link 3 14 is hinged to the bend of link 2 13.

[0026] Furthermore, two hinge blocks are installed on the bottom surface of the connecting block 15. The other end of the connecting rod 12 is hinged to one of the hinge blocks at the bottom of the connecting block 15, and the other end of the connecting rod 13 is hinged to the other hinge block at the bottom of the connecting block 15. A support plate is fixedly installed on the upper surface of the connecting block 15, and a surrounding plate is installed on three sides of the upper plane of the support plate. The support plate and the surrounding plate together constitute the connecting seat.

[0027] Furthermore, the quick-change assembly includes a sliding block 17, a wedge block 18, and a spring 19. The spring 19 is fixedly installed in the middle of the upper surface of the support plate on the connecting block 15. The sliding blocks 17 are symmetrically slidably connected to the upper surface of the support plate corresponding to the two sides of the spring 19. The opposing surfaces of the two sliding blocks 17 are inclined. The wedge block 18 is fixedly installed on the other end of the spring 19. The two sides of the wedge block 18 are inclined. The two sides of the wedge block 18 correspond to the sidewalls of the sliding block 17; A fixing groove is formed between the plane of the sliding block 17 and the surrounding plate on the connecting block 15.

[0028] Furthermore, one side of the V-groove module 16 is V-shaped, and a rubber block is fixedly installed on the V-shaped surface. Connecting blocks are symmetrically fixedly installed on the other side of the V-groove module 16. The connecting block and fixing slot on the V-groove module 16 are snapped together.

[0029] Structural Description: Support 1: Support 1 is the basic support structure of the equipment. It is frame-shaped and has rotatably connected pulleys 3 at the front and rear ends inside. The upper plane is symmetrically fixed with limit plates to limit and guide the base 5, ensuring that the base 5 moves smoothly along the conveyor belt 4, and at the same time providing installation support for components such as motor 2 and pulleys 3. Motor 2: The equipment is equipped with multiple motors 2. Among them, the motor 2 on the side of the support 1 is used to drive the pulley 3 to rotate, the motor 2 in the base 5 drives the planetary gear set to rotate, and the motor 2 fixed on the bottom surface of the base 9 can adjust the action of the clamping mechanism as needed. It is the core component of the equipment's power output. Pulley 3: Pulley 3 is a cylindrical structure. The front and rear pulleys 3 are installed inside the support 1 and are connected by the conveyor belt 4. Under the drive of the motor 2, the conveyor belt 4 is driven to rotate in a cycle, providing conveying power to the base 5 and the planetary gear turntable. Conveyor belt 4: The conveyor belt 4 is wrapped around the outside of the two pulleys 3 in a ring shape. A base 5 is fixed on its plane. The continuous conveying of the base 5 is achieved by the rotation of the pulleys 3. Base 5: Base 5 is fixed on conveyor belt 4 and is disc-shaped. It has a motor 2 that drives planetary gear set installed inside. The upper surface is equipped with planetary gear set. The outer arc surface is tangent to the inner wall of the support 1 limiting plate to ensure stability when moving with conveyor belt 4. Pinion 6: Pinion 6 is a cylindrical gear, which is distributed in a ring at equal intervals on the base 5. It meshes with pinion 7 and drives the fixed base 9 to move through planetary gear transmission, thereby realizing the multi-directional angle adjustment of the clamping mechanism. Small gear 27: Small gear 27 is also a cylindrical gear, which is mounted in a ring at equal intervals on the base 5. It meshes with large gear 8 and small gear 16 respectively. Under the drive of large gear 8, it drives small gear 16 to rotate. It is the intermediate transmission component in the planetary gear set. Large gear 8: Large gear 8 is mounted on base 5 and is fixed coaxially with the output shaft of motor 2 inside base 5. It drives the entire planetary gear set to rotate through meshing with small gear 7. It is the driving gear of planetary gear turntable transmission. Fixed base 9: Fixed base 9 is coaxially mounted on pinion 6 and is disc-shaped. The bottom surface is connected to motor 2. The upper surface is symmetrically provided with two sets of hinge seat assemblies of different heights and a central threaded hole for installing the lead screw 11 and connecting rod assembly of the clamping mechanism. Sliding seat 10: The sliding seat 10 is threadedly connected to the support 1. The outer arc surface is provided with a hinge seat, which is hinged to the connecting rod 14. When the lead screw 11 rotates, it moves along the support 1 and drives the connecting block 15 to move through the connecting rod transmission, thereby realizing the opening and closing of the clamping mechanism. Lead screw 11: The lead screw 11 is installed in the threaded hole of the fixed base 9. When rotated, it can drive the sliding seat 10 to move along the support 1. It is a key part in the clamping mechanism to realize the conversion between linear motion and linkage transmission. It transmits power through threaded engagement. Link 12: Link 12 is a straight rod, with one end hinged to the higher hinge block of the fixed base 9 and the other end hinged to the bottom of the connecting block 15. When the sliding seat 10 moves, it drives the connecting block 15 to swing through the linkage transmission, thus participating in the clamping action. Link 2 13: Link 2 13 is a curved link with an obtuse angle. One end is hinged to the shorter hinge block of the fixed base 9, and the other end is hinged to the bottom of the connecting block 15. The middle bend is hinged to link 3 14. The clamping force is transmitted through the linkage of multiple links. Link 3 14: Link 3 14 is a straight rod, with both ends hinged to the sliding seat 10 and the bend of link 2 13 respectively. When the sliding seat 10 moves, it pushes link 2 13 to swing, thereby driving the connecting block 15 and the V-groove module 16 to complete the clamping or releasing action. Connecting block 15: The bottom surface of connecting block 15 is provided with two hinge blocks that are hinged to connecting rod 12 and connecting rod 2 13. The upper surface is fixed with a support plate, and the three sides are provided with a surrounding plate to form a connecting seat, which is used to install quick-change assembly and V-groove module 16. It is the connecting carrier between clamping mechanism and quick-change assembly. V-groove module 16: One side of the V-groove module 16 is a "V" shaped groove surface with rubber blocks attached to the groove surface for clamping the pen refill. The other side is provided with symmetrical connecting blocks that engage with the fixing groove on the connecting block 15. It is a functional component that directly clamps the pen refill and can be quickly replaced by a quick-change assembly. Sliding block 17: Sliding block 17 is symmetrically installed on the support plate of connecting block 15 and can slide along the support plate. The opposite surfaces are inclined and cooperate with wedge block 18 to form a fixing groove through sliding. It is used to snap the connecting block of V-groove module 16 to realize the quick fixing of the module. Wedge block 18: The two sides of the wedge block 18 are inclined and fit against the opposite side of the sliding block 17. The bottom is connected to the support plate through the spring 19. When pressed, the spring 19 is compressed to move the sliding block 17 outward. After releasing, the spring returns to its original position and pushes the sliding block 17 to clamp the V-groove module 16, realizing the quick change function. Spring 19: Spring 19 is mounted on the support plate of connecting block 15, with one end fixed and the other end connected to wedge block 18. The wedge block 18 is pushed back by elastic force, so that sliding block 17 clamps V-groove module 16. It is an elastic element that provides clamping force in quick-change assembly.

[0030] Working principle: After the motor 2 on the support 1 side starts, the output shaft drives the pulley 3 to rotate, which in turn causes the conveyor belt 4 surrounding the two pulleys 3 to circulate. The base 5 fixed on the plane of the conveyor belt 4 moves accordingly. The outer arc surface of the base 5 is tangent to the inner walls of the upper limit plate on both sides of the support 1, ensuring that it moves smoothly along the conveyor belt 4. When the base 5 moves to the designated position, the motor 2 inside the base 5 starts, and the output shaft drives the large gear 8 to rotate. The large gear 8 meshes with the small gear 7 that is equidistantly distributed in a ring on the base 5, thereby driving the small gear 7 to rotate. The small gear 7 then meshes with the small gear 6 that is equidistantly distributed in a ring on the base 5, causing the small gear 6 to rotate. The fixed base 9, which is coaxially fixedly installed with the small gear 6, rotates accordingly, realizing the angle adjustment of the clamping mechanism.

[0031] When the lead screw 11 on the fixed base 9 rotates, it is connected to the threaded hole on the fixed base 9, and the sliding seat 10 is threaded to the support 1. The rotation of the lead screw 11 will drive the sliding seat 10 to move along the support 1. The hinge seat symmetrically fixed on the outer arc surface of the sliding seat 10 has a connecting rod 14 hinged inside. When the sliding seat 10 moves, it pushes the connecting rod 13 to swing through the connecting rod 14. One end of the connecting rod 13 is hinged to the lower hinge block on the fixed base 9, and the other end is hinged to the bottom of the connecting block 15. The middle bend is hinged to the connecting rod 14. At the same time, the connecting rod 12 hinged on the higher hinge block on the fixed base 9 will also drive the connecting block 15 to swing. The two hinge blocks on the bottom surface of the connecting block 15 are respectively hinged to the connecting rod 12 and the connecting rod 13. The support plate fixed on the upper surface has a three-sided mounting plate to form a connecting seat. The quick-change assembly and the V-groove module 16 are installed on the connecting seat.

[0032] When the sliding seat 10 moves, the linkage of connecting rod 12, connecting rod 23 and connecting rod 314 causes the connecting block 15 to drive the V-groove module 16 to perform clamping or releasing actions. One side of the V-groove module 16 is V-shaped, and the rubber block fixedly installed on the V-shaped surface can increase friction and stably clamp the pen refill. The connecting block symmetrically fixedly installed on the other side engages with the fixing groove on the connecting block 15. When the V-groove module 16 needs to be replaced, press the wedge block 18 to compress the spring 19, causing the sliding block 17 to move outward and the fixing groove to enlarge, so that the V-groove module 16 can be quickly disassembled. During installation, the connecting block of the V-groove module 16 is placed into the fixing groove, the wedge block 18 is released, the spring 19 returns to its original position and pushes the wedge block 18, so that the sliding block 17 clamps the connecting block of the V-groove module 16, achieving quick installation.
