Description

Technical Field

[0001] The utility model relates to the technical field of plastic bottle cap processing, in particular to a device for cutting off the edges and corners of a plastic bottle cap. Background Technique

[0002] Plastic caps are a common packaging form for bottles, cans, and barrels, and are particularly widely used in the fields of beverages, chemicals, and pharmaceuticals. According to their uses, they can be divided into breathable plastic caps and non-breathable plastic caps. When plastic bottle caps are produced, they generally go through injection molding and hot pressing, and then cooperate with molds to complete the finished products. Subsequently, the protruding edges and corners of these finished products will be polished and processed later to ensure the installation quality of the bottle caps.

[0003] However, when the existing plastic bottle cap cutting device is in use, the bottle cap is manually placed on the clamping seat, and then the outer periphery of the bottle cap is polished and trimmed by starting the scraper, resulting in a relatively low overall efficiency during the edge trimming process. For this reason, we propose a device for cutting off the edges and corners of a plastic bottle cap. Content of the Utility Model

[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art, and provides a device for cutting off the edges and corners of a plastic bottle cap.

[0005] To achieve the above object, the utility model adopts the following technical scheme. A device for cutting off the edges and corners of a plastic bottle cap includes a base and a support table. A servo cylinder is installed on the top of the support table. A through groove is opened on the top of the support table. The bottom of the servo cylinder is provided with a drive shaft assembly that penetrates through the through groove. The bottom of the drive shaft assembly is installed with a cutting sleeve for cutting and processing the outer periphery of the bottle cap. A conveyor belt is arranged on one side of the support table and is peripherally driven and sleeved by a connecting shaft. A buffer pad is installed on the surface of the conveyor belt. An upper limit seat pad for limiting the bottle cap is integrally formed above the buffer pad. An inner support plate for supporting the inner side of the conveyor belt is installed on one side of the support table. A collection box for collecting the processed materials is arranged above the base.

[0006] Preferably, when the conveyor belt moves to drive the bottle cap sleeved outside the limit seat pad to move to the position of the cutting sleeve, the servo cylinder starts to drive the cutting sleeve to perform a one-time downward cutting state on the outer periphery of the bottle cap through the drive shaft assembly.

[0007] Preferably, both the buffer pad and the limit seat pad have deformation characteristics. When the servo cylinder starts to drive the cutting sleeve to move downward to cut the bottle cap through the drive shaft assembly, the upper end of the buffer pad is in contact with the lower end of the cutting sleeve in a buffer state.

[0008] Preferably, a support plate is installed on one side of the support table, a servo motor is installed on the front side of the support plate, the output shaft end of the servo motor is drivingly connected to a rotating shaft passing through the support plate, and the end of the rotating shaft is drivingly connected and matched with one end of a set of connecting shafts.

[0009] Preferably, the drive shaft assembly is composed of an upper shaft and a lower shaft. An inner cavity is formed inside the upper shaft, a telescopic shaft fixedly connected to the lower shaft is arranged inside the inner cavity, the end of the telescopic shaft is in limit fit with the inside of the inner cavity through a limiting member, and a buffer spring supporting and connecting with the limiting member is arranged inside the inner cavity.

[0010] Preferably, when the servo cylinder drives the cutting sleeve to contact the buffer pad through the drive shaft assembly during startup, the lower shaft is in a state of squeezing and buffering the buffer spring inside the inner cavity through the limiting member at the end of the telescopic shaft.

[0011] The utility model provides a device for cutting the edges of plastic bottle caps. It has the following beneficial effects:

[0012] 1. For this device for cutting the edges of plastic bottle caps, in this article, a conveyor belt for batch conveying of bottle caps is arranged on one side of the support table, and the bottle caps to be edge-cut can be sleeved outside the limit seat cushion for positioning. When the servo motor starts and controls the bottle caps on the conveyor belt to move to the bottom position of the cutting sleeve through the connecting shaft, the servo cylinder can start to drive the cutting sleeve at the bottom of the drive shaft assembly to move downward, so as to directly cut and trim the outside of the bottle cap integrally. There is no need to slowly grind with a cutter, which reduces the efficiency. Moreover, the conveyor belt and the cutting sleeve feed each other, so as to achieve the effect of improving the edge-cutting processing efficiency of the bottle cap.

[0013] 2. For this device for cutting the edges of plastic bottle caps, the drive shaft assembly is composed of an upper shaft and a lower shaft. When the servo cylinder drives the cutting sleeve to move downward to cut the bottle cap through the drive shaft assembly after startup, the lower end of the cutting sleeve can be in extrusion contact with the upper end of the buffer pad, and preliminary protection is carried out through the characteristics of the buffer pad itself. When the drive shaft assembly continues to be extruded, the lower shaft can perform telescopic movement into the upper shaft through the telescopic shaft, and the buffer spring inside the inner cavity can buffer and support the cutting pressure generated by the cutting sleeve, avoiding direct excessive pressure, so as to achieve the effect of improving the self-protection of the cutting sleeve and extending the service life of the cutting sleeve.

[0023] Embodiment: A device for cutting off the corners of plastic bottle caps, as Figures 1-4As shown in the figure, it includes a base 1 and a support platform 2. A servo cylinder 3 is installed on the top of the support platform 2. A through groove 4 is opened on the top of the support platform 2. The bottom of the servo cylinder 3 is provided with a drive shaft assembly 5 that penetrates through the through groove 4. The bottom of the drive shaft assembly 5 is installed with a cutting sleeve 6 for cutting the periphery of the bottle cap. A support plate 7 is installed on one side of the support platform 2. A servo motor 8 is installed on the front side of the support plate 7. The output shaft end of the servo motor 8 is drivingly connected to a rotating shaft 9 that penetrates through the support plate 7. One end of the rotating shaft 9 is drivingly connected and matched with one end of a group of connecting shafts 10. A conveyor belt 11 is sleeved on the outside of the connecting shaft 10 on one side of the support platform 2. A buffer pad 12 is installed on the surface of the conveyor belt 11. An upper limit seat pad 13 for limiting the bottle cap is integrally formed above the buffer pad 12. An inner support plate 14 for supporting the inside of the conveyor belt 11 is installed on one side of the support platform 2. A collection box 15 for collecting the processed materials is arranged above the base 1. The drive shaft assembly 5 is composed of an upper shaft 16 and a lower shaft 17. An inner cavity 18 is opened inside the upper shaft 16. An expansion shaft 19 fixedly connected to the lower shaft 17 is arranged inside the inner cavity 18. The end of the expansion shaft 19 is limited and matched with the inside of the inner cavity 18 through a limiting member 20. A buffer spring 21 that is supported and connected to the limiting member 20 is arranged inside the inner cavity 18.

[0024] Further, when the conveyor belt 11 moves to drive the bottle cap sleeved and limited outside the limit seat pad 13 to move to the position of the cutting sleeve 6, the servo cylinder 3 starts to drive the cutting sleeve 6 through the drive shaft assembly 5 to perform a one-time downward cutting state on the periphery of the bottle cap.

[0025] Further, both the buffer pad 12 and the limit seat pad 13 have deformation characteristics. When the servo cylinder 3 starts to drive the cutting sleeve 6 to move downward through the drive shaft assembly 5 to cut the bottle cap, the upper end of the buffer pad 12 is in contact with the lower end of the cutting sleeve 6 in a buffer state.

[0026] Further, when the servo cylinder 3 starts to drive the cutting sleeve 6 to contact the buffer pad 12 through the drive shaft assembly 5, the lower shaft 17 squeezes the buffer spring 21 inside the inner cavity 18 through the limiting member 20 at the end of the expansion shaft 19 in a buffer state.

[0027] The working principle of the present utility model:

[0028] On one side of the support table 2, there is a conveyor belt 11 for batch conveying of bottle caps. The bottle caps to be trimmed can be sleeved outside the limit seat cushion 13 for positioning. When the servo motor 8 is started and the bottle caps on the conveyor belt 11 are controlled by the connecting shaft 10 to move to the bottom position of the cutting sleeve 6, the servo cylinder 3 can be started to drive the cutting sleeve 6 at the bottom of the drive shaft assembly 5 to move downward, so as to directly cut and trim the outside of the bottle cap integrally. There is no need to slowly grind with a cutter, which reduces the efficiency. Moreover, the conveyor belt 11 and the cutting sleeve 6 feed and supply materials to each other, thereby improving the efficiency of bottle cap trimming. The drive shaft assembly 5 is composed of an upper shaft 16 and a lower shaft 17. When the servo cylinder 3 drives the cutting sleeve 6 to move downward to cut the bottle cap after being started through the drive shaft assembly 5, the lower end of the cutting sleeve 6 can be in extrusion contact with the upper end of the buffer pad 12, and preliminary protection is carried out through the characteristics of the buffer pad 12 itself. When the drive shaft assembly 5 continues to be extruded, the lower shaft 17 can move telescopically into the upper shaft 16 through the telescopic shaft 19, and the buffer spring 21 inside the inner cavity 18 can buffer and support the cutting pressure generated by the cutting sleeve 6, avoiding direct excessive compression.
