Description

Technical Field

[0001] This invention relates to injection molding technology, and more particularly to a pen barrel production equipment with a protective sleeve. Background Technology

[0002] Plastic pens are manufactured using injection molding machines. Traditionally, after demolding, the pen barrels fall freely into a collection tank at the bottom of the injection molding machine due to gravity. Workers then retrieve the pen barrels and place them in a transport box for further assembly. In practice, the pen barrels easily scrape against each other as they fall, resulting in defective products that must be broken and recycled. Furthermore, workers need to pick up the pen barrels and arrange them in a uniform orientation, making the process cumbersome, time-consuming, and labor-intensive. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this invention proposes a pen barrel production device with a protective sleeve.

[0004] A pen barrel manufacturing device with a protective sleeve, comprising: A base, on which an extrusion mechanism and a molding mechanism are provided. The extrusion mechanism is used to extrude molten plastic particles, and the molding mechanism is a mold used to mold the pen barrel. A transfer mechanism is provided at the upper end of the forming mechanism. The transfer mechanism includes a first slide rail, a second slide rail, a cylinder, and a holding mechanism. The second slide rail is installed at the lower end of the first slide rail, the cylinder is located at the lower end of the second slide rail, and the holding mechanism is located at the lower end of the cylinder. The first slide rail and the second slide rail are arranged perpendicularly. The retaining mechanism includes: A fixed cover, wherein a first sliding hole and a second sliding hole are respectively provided at both ends of the fixed cover; A driving component is disposed in the middle of the fixed cover, with one end of the driving component disposed in the first sliding hole and the other end disposed in the second sliding hole; A mounting plate is provided at the lower end of the fixed cover.

The retaining assembly includes a mounting component, a gear component, and symmetrically arranged retaining rods. The mounting component and the gear component are mounted in a mounting hole via a rotating shaft. The gear is meshed with a driving component. The retaining rods are respectively disposed at both ends of the mounting component, and a retaining area is formed between the retaining rods. The drive unit drives the gear to rotate, and the rotation of the retaining assembly applies external pressure to the pen barrel that has entered the retaining area, placing it on the baffle.

[0005] In this invention, the fixing cover consists of a fixing plate, a first side plate and a second side plate. The first sliding hole is disposed on the first side plate and the second sliding hole is disposed on the second side plate. An active area is formed between the first side plate and the second side plate, and the driving member is disposed within the active area.

[0006] In this invention, the driving member consists of a driving rod, a first sliding rod disposed at one end of the driving rod, and a second sliding rod disposed at the other end of the driving rod.

[0007] In this invention, a spring is fitted on the first sliding rod, one end of which contacts the driving rod and the other end contacts the first side plate.

[0008] In this invention, an electromagnetic component is sleeved on the second sliding rod, the electromagnetic component is installed on the second side plate, and the second sliding rod passes through the electromagnetic component and enters the second sliding hole.

[0009] In this invention, a magnet is provided at the lower end of the drive rod, and the first and second sliding rods are made of non-metallic materials.

[0010] In this invention, the drive rod is provided with multiple teeth, which mesh with gears.

[0012] In this invention, a through hole is formed in the middle of the elastic sleeve, and the inner diameter of the through hole is smaller than the outer diameter of the retaining rod.

[0013] The pen barrel production equipment with a protective sleeve according to the present invention has the following beneficial effects: The equipment employs a rotating structure, which allows force to be applied to both ends of the pen barrel on the mold core, placing it on the baffle and maintaining its position. Furthermore, the holding component can rotate and open, adapting to pen barrels of different diameters, and can also clamp and transfer different numbers of pen barrels. In use, simply controlling the movement of the holding mechanism and energizing the electromagnetic component controls the holding component to clamp the pen barrel. The operation is fast, adaptable to different pen barrels, and automated, which helps improve overall work efficiency and reduce the labor intensity of workers. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0017] like Figures 1 to 7 As shown, the pen barrel production equipment of the present invention includes a base 1, an extrusion mechanism 2, a molding mechanism 3, a transfer mechanism 4, and a holding mechanism 5. The extrusion mechanism 2 and the molding mechanism 3 are disposed on the base 1. The extrusion mechanism 2 is used to extrude molten plastic particles, and the molding mechanism 3 is a mold used to mold the pen barrel 6.

[0018] This application includes a moving template 7, a fixed template 8, and a push plate 9. Other structures are also provided, and existing technologies can be used to form the mold, so they will not be described in detail here.

[0019] The transfer mechanism 4 is located at the upper end of the forming mechanism 3. The transfer mechanism 4 includes a first slide rail 10, a second slide rail 11, a cylinder 12, and a holding mechanism 5. The second slide rail 11 is installed at the lower end of the first slide rail 10, the cylinder 12 is located at the lower end of the second slide rail 11, and the holding mechanism 5 is located at the lower end of the cylinder 12. The first slide rail 10 and the second slide rail 11 are arranged perpendicularly. The first slide rail 10 drives the second slide rail 11 to move, achieving lateral sliding of the second slide rail 11. The second slide rail 11, in turn, drives the cylinder 12 to move back and forth. The cylinder 12 drives the holding mechanism 5 to move up and down, thereby achieving the transfer of the pen barrel 6.

[0020] The retaining mechanism 5 includes a fixed cover 13, a driving member 14, a mounting plate 15, and a retaining assembly 16. The fixed cover 13 is connected to the lower end of the cylinder 12. The driving member 14 is used to drive the retaining assembly 16 to rotate. The retaining assembly 16 is provided in several parts and is mounted on the mounting plate 15. This allows the retaining assembly 16 to apply force to the pen barrel 6 that extends into the retaining area 17, press it against the baffle 18, thereby positioning the pen barrel 6, clamping it, and transferring it.

[0021] The fixed cover 13 has a first sliding hole 19 and a second sliding hole 20 at both ends. The first sliding hole 19 and the second sliding hole 20 are used for the sliding of the drive member 14, so that it can move within the active area 21.

[0022] The driving component 14 is located in the middle of the fixed cover 13. One end of the driving component 14 is located in the first sliding hole 19, and the other end is located in the second sliding hole 20. The driving component 14 drives the gear 22 to rotate, and through the rotation of the retaining assembly 16, it applies external pressure to the pen barrel 6 that has entered the retaining area 17 and places it on the baffle 18.

[0023] The driving component 14 consists of a driving rod 23, a first sliding rod 24 disposed at one end of the driving rod 23, and a second sliding rod 25 disposed at the other end of the driving rod 23. A spring 26 is fitted onto the first sliding rod 24, with one end of the spring 26 contacting the driving rod 23 and the other end contacting the first side plate 27. An electromagnetic component 28 is fitted onto the second sliding rod 25, and the electromagnetic component 28 is mounted on the second side plate 29. The second sliding rod 25 passes through the electromagnetic component 28 and enters the second sliding hole 20.

[0024] The electromagnetic component 28 can push the drive rod 23 to move, thereby compressing the spring 26. When the electromagnetic component 28 is not energized, it will not generate magnetic force, and the spring 26 can push the drive component 14 downward, causing the drive rod 23 to drive the gear 22 to rotate, thereby resetting the retaining assembly 16. The electromagnetic component 28 is only energized when the pen 6 enters the retaining area 17, so that the pen 6 is subjected to force and positioned within the retaining area 17 and placed on the baffle 18.

[0025] A magnet (not shown in the figure) is installed at the lower end of the drive rod 23, and the magnet is located at the upper end of the second sliding rod 25. The first sliding rod 24 and the second sliding rod 25 are made of non-metallic materials. The drive rod 23 has multiple teeth 30, which mesh with the gear 22. This allows the electromagnetic component 28 to push the drive rod 23, thereby compressing the spring 26.

[0026] Mounting plate 15 is located at the lower end of fixed cover 13. Mounting plate 15 has several mounting holes 31 and several baffles 18, which are staggered. The baffles 18 are used to support one end of pen barrel 6, so that the other end of pen barrel 6 is lifted by force, and then the other end can be pressed against the baffle 18.

[0027] The retaining assembly 16 includes a mounting member 32, a gear member 22, and symmetrically arranged retaining rods 33. The mounting member 32 and the gear member 22 are disposed in the mounting hole 31 via a rotating shaft 34. The gear 22 is meshed with the driving member 14. The retaining rods 33 are respectively disposed at both ends of the mounting member 32, and a retaining area 17 is formed between the retaining rods 33.

[0028] The fixed cover 13 consists of a fixed plate 35, a first side plate 27 and a second side plate 29. A first sliding hole 19 is provided on the first side plate 27 and a second sliding hole 20 is provided on the second side plate 29. An active area 21 is formed between the first side plate 27 and the second side plate 29, and a driving member 14 is provided in the active area 21.

[0029] An elastic sleeve 36 is fitted onto the retaining rod 33. The elastic sleeve 36 can deform under force. The elastic sleeve 36 can be a rubber sleeve or a foam sleeve. A through hole 37 is formed in the middle of the elastic sleeve 36, and the inner diameter of the through hole 37 is smaller than the outer diameter of the retaining rod 33. When installing the elastic sleeve 36, it is necessary to make the elastic sleeve 36 deform to a certain extent under force, so that the force on the elastic sleeve 36 is restricted to the retaining rod 33 and will not be removed from the retaining rod 33.

[0030] like Figure 7As shown, a mold core 38 is provided on the moving template 7, and the mold core 38 passes through the push plate 9. After the pen barrel 6 is formed, the pen barrel 6 formed on the mold core 38 can be pushed out by the push plate 9. At this time, the holding component 16 can move on the first slide rail 10 via the second slide rail 11, so that the holding mechanism 5 is close to the mold core 38. At this time, the mounting component 32 is in an inclined state because the spring 26 pushes the drive rod 23 to move down, so that the magnet at the lower end of the drive rod 23 contacts the electromagnetic component 28, and the electromagnetic component 28 is in a non-energized state. One holding rod 33 is at the lower end of the pen barrel 6, and the other holding rod 33 is at the upper end of the pen barrel 6, so that the pen barrel 6 is between the baffle 18 and the other holding rod 33. At this time, the electromagnetic component 28 is energized, so that the electromagnetic component 28 pushes the magnet to move up, driving the drive component 14 to move up, compressing the spring 26. The gear 22 is driven to rotate by the toothed teeth 30, which in turn drives the mounting component 32 to rotate via the rotating shaft 34. This causes the two retaining rods 33 to rotate towards the pen barrel 6, clamping the pen barrel 6 between the two retaining rods 33. At this time, the pen barrel 6 is still on the mold core 38 and is in a horizontal state. When the push plate 9 pushes the pen barrel 6, the pen barrel 6 just detaches from the mold core 38. The end of the pen barrel 6 away from the push plate 9 can be pressed against the baffle 18 by the retaining rods 33, thus restricting the position of the pen barrel 6 by the pressure exerted by the retaining rods 33 on the baffle 18.

[0031] Meanwhile, since the elastic sleeve 36 has a certain degree of elasticity, when the pen barrel 6 is pressed onto the elastic sleeve 36 on the retaining rod 33, the pen barrel 6 can be pressed onto the elastic sleeve 36, causing the elastic sleeve 36 to deform and form a groove on the elastic sleeve 36. This can restrict the position of the pen barrel 6 and prevent the pen barrel 6 from slipping at the moment of separation from the mold core 38, which would affect the position of the pen barrel 6 and cause the pen barrel 6 to fall out of the retaining assembly 16.

[0032] Once the pen barrel 6 is restrained by the holding mechanism 5, multiple pen barrels 6 can be transferred directly from the mold core 38 to the conveyor belt through the cooperation of the first slide rail 10, the second slide rail 11, and the cylinder 12. This avoids confusion in the orientation of the pen barrels 6 and eliminates the need for manual placement by staff, thereby further improving work efficiency, reducing the labor intensity of staff, and achieving automated operation.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
