Description

Technical Field

[0001] The present invention belongs to the technical field of helmet production, and particularly relates to a cutting device for helmet production. Background Art

[0002] In today's society, helmets, as an important safety protection equipment, are widely used in multiple fields such as transportation and industrial production. Especially helmets made of plastic materials have become the mainstream products in the market due to their advantages such as light weight, low cost, and strong plasticity. During the production process of plastic helmets, the injection molding process is usually adopted. In this process, molten plastic is injected into the mold cavity, and after the plastic cools and solidifies, the basic shape of the helmet can be obtained. However, this production method will inevitably generate some flash, burrs, overflow materials, etc. at the bottom of the helmet. The existence of these impurities will seriously affect the quality and performance of the helmet.

[0003] However, when existing cutting devices are in use, most of them cut horizontally or vertically. Due to the unique hollow spherical shape of the helmet, it is difficult to perform automated cutting according to its shape. Moreover, most existing clamps are difficult to fit and hold it, and it is easy to displace and difficult to limit the position during cutting, which affects the stability and cutting accuracy during cutting and also increases the scrap rate during helmet production. Summary of the Invention

[0004] The purpose of the present invention is to provide a cutting device for helmet production to solve the problems raised in the above background art.

[0005] In view of this, the present invention provides a cutting device for helmet production, including: A fixed seat, a support rod is fixed at the top of the fixed seat, limit claws are fixed around the surface of the support rod, and a helmet body is movably sleeved at the top of the limit claws; A fixing component, which is arranged above and on one side of the fixed seat and is used to fix the helmet body; Connection columns are fixed around the surface of the fixed seat, a fixed gear is fixed on the other side of the connection column, a fixed ring is fixed at the bottom of the fixed gear, an inner annular groove and an outer annular groove are respectively formed on the inner side and the outer side of the fixed ring, a support plate is arranged on one side of the fixed ring, a first motor is installed at the top of one end of the support plate, a moving gear is fixed at the coupling end of the first motor, a movable column is fixed on one side of the first motor, an L-shaped plate is fixed on one side of the support plate, and a rotating column is movably inserted in the L-shaped plate, and a connecting plate is fixed at the top of the support plate; A fixing plate is fixed to one side of the connecting plate, a No. 3 electric push rod is fixed to the top of the fixing plate, a push plate is fixed to the top of the No. 3 electric push rod, a No. 2 electric push rod is installed on one side of the connecting plate, a No. 2 motor is fixed to the piston end of the No. 2 electric push rod, and a cutting disc is fixed to the coupling end of the No. 2 motor; A limiting component is arranged on one side of the second motor and one side of the top of the fixing plate, and is used to limit the position of the helmet body.

[0006] In the above technical solution, further, the fixing assembly includes a support frame, which is fixed to the ground by expansion bolts, and one end of the fixing seat is equipped with an electric push rod No. 1, and the bottom end of the electric push rod No. 1 is fixed with a limiting disc, and the bottom end of the limiting disc is provided with an arc-shaped groove, and the arc-shaped groove cooperates with the top of the helmet body. After the helmet body is placed on the support rod, the electric push rod No. 1 is started to push the limiting disc downward to move to the top of the helmet body to fix the helmet body. After the cutting is completed, the electric push rod No. 1 is started in the same reverse direction, and the piston end of the electric push rod No. 1 drives the limiting disc away from the helmet body, so that the processed helmet body can be taken out.

[0007] In the above technical solution, further, the limiting assembly includes a fixing frame, which is fixed at one end of the fixing plate, and connecting frames are fixed on both sides of the top of the fixing frame. Two No. 1 rollers are rotatably provided on the surfaces of the two connecting frames, and multiple No. 1 rollers are in contact with the inner wall of the helmet body. As the support plate and the connecting plate move, the No. 1 rollers are driven to roll in a circular manner on different surfaces of the inner wall of the helmet body, thereby facilitating the limiting of the helmet body during cutting, reducing displacement and shaking during cutting, and increasing stability during resection production.

[0008] In the above technical solution, further, the limiting assembly also includes a No. 2 motor, and fixed rods are symmetrically fixed on both sides of the No. 2 motor, and moving rods are fixed in the two fixed rods respectively. The surfaces of the two moving rods are movably sleeved with springs, and the top ends of the two moving rods are fixed with limiting frames respectively. The surfaces of the limiting frames on both sides are rotatably provided with No. 2 rollers. After the helmet body is placed on top of the support rod, the No. 1 electric push rod and the No. 2 electric push rod are started synchronously. As the No. 2 electric push rod moves, the two moving rods are pushed toward the helmet body. According to the thickness and position of the helmet body, the moving rod is retracted into the fixed rod, which increases the flexibility and adjustability of the device during use. At the same time, the inner wall and outer wall of the helmet body are jointly limited, which further increases the reliability during cutting.

[0009] In the above technical solution, further, a plurality of first rollers and second rollers are respectively provided. The plurality of first rollers and second rollers are distributed vertically. The plurality of first rollers and second rollers located above are arranged in an inclined shape. The horizontal distance between the plurality of first rollers is smaller than the distance between the plurality of second rollers. Rubber pads are fixedly laid on the surfaces of the plurality of first rollers and second rollers. The surfaces of the plurality of first rollers and second rollers are respectively in contact with and roll on the inner and outer walls of the helmet body. Through the inclined arrangement of the first rollers and the horizontal first rollers, the inner wall arc of the helmet body is fitted. Also, with the movement of the rotation cutting, the limiting component is driven to rotate and limit around the helmet body. The rubber material has good friction and certain elasticity, increasing the friction of the contact surface with the helmet body, thereby increasing the stability of the position of the helmet body and also protecting the surface of the helmet body.

[0010] In the above technical solution, further, a square groove is opened at the top end of the support plate. A slider is movably inserted into the square groove. A second motor is fixed to the top end of the slider, defining the moving direction and position of the second motor, reducing the deviation and position after long-term use, and also avoiding the collision with the push plate, increasing the rationality of the equipment.

[0011] In the above technical solution, further, the fixed gear is adapted to the moving gear. The fixed gear and the moving gear are meshed. The top end of the moving gear is rotatably inserted with the bottom end of the connecting plate. After starting the first motor, the moving gear is driven to rotate. Thus, the moving gear meshes and rotates in a circular manner on the surface of the fixed gear, cutting and removing the burrs of the helmet body.

[0012] In the above technical solution, further, a plurality of limiting claws are provided. The plurality of limiting claws are evenly distributed in a circular manner with the support rod as the center. The plurality of limiting claws are arranged in an "L" shape. One end of the plurality of limiting claws is arranged in an inclined shape. The top ends of the plurality of limiting claws are in contact and cooperate with the top end of the inner wall of the helmet body, fixing and limiting the helmet body from the bottom end. The limiting claws cooperate with the limiting disc, enabling the helmet body to be fixed up and down by the limiting claws and the limiting disc. The inclined arrangement of the plurality of limiting claws increases the clamping area.

[0013] In the above technical solution, further, a rotating column is movably inserted into the inner annular groove, and a movable column is movably inserted into the outer annular groove. There is a gap between the inner annular groove and the outer annular groove. Two L-shaped plates are symmetrically arranged. The two L-shaped plates are located below the fixed ring. The length of the L-shaped plate is greater than the width of the fixed ring. The push plate is located between the fixed frame and the moving rod. The push plate is in contact with the burr of the helmet body in a matching manner. After the moving gear and the support plate rotate, the rotating column and the movable column roll and move in the inner annular groove and the outer annular groove of the fixed ring, so that the support plate and the connecting plate can move stably in cooperation.

[0014] In the above technical solution, further, the push plate is located between the fixed frame and the moving rod. The push plate is in contact with the burr of the helmet body in a matching manner. After the cutting is completed, the third electric push rod is started to push the push plate upward to move, and the burr is pushed upward, so that the burr is inclined and convenient to take out, reducing the burr from being stuck and falling into the middle of the connecting frame and the connecting plate, and improving the processing efficiency.

[0015] The beneficial effects of the present invention are: 1. For the helmet production cutting equipment, by placing the helmet body above multiple limit claws and starting the first electric push rod to drive the limit disc to move downward, the multiple limit claws and the arc-shaped grooves at the bottom of the limit disc clamp and fix the helmet body, so that the top of the helmet body is fixed and clamped, thereby exposing the burrs around the helmet body, facilitating cutting and processing, and reducing the shaking and displacement during processing; 2. For the helmet production cutting equipment, the first electric push rod and the second electric push rod are started at the same time. The piston end of the second electric push rod pushes the second motor and moves towards the helmet body, while limiting the position of the helmet body and the cutting position. After the limiting and cutting are completed, the first electric push rod and the second electric push rod are started in reverse at the same time to release the limit on the helmet body, facilitating clamping and fixing and taking out the helmet body, increasing the production efficiency, and thus increasing the production volume of helmets in the same period; 3. For the helmet production cutting equipment, the second electric push rod pushes the second motor and the moving rod towards the position of the helmet body, adjusts according to the position and wall thickness of the helmet body, the moving rod retracts into the fixed rod, so that the spring rebounds under force, limiting the cutting area on the outer wall of the helmet body. At this time, multiple first rollers and second rollers fix and limit the cutting position of the helmet body. The cutting blade cuts between the multiple first rollers and second rollers. As the cutting blade performs circumferential cutting, the multiple first rollers and second rollers keep rolling and displacing on the inner and outer walls of the helmet body, so that the cutting blade can cut stably, maintaining the stability of the cutting position, thereby increasing the flatness of the helmet body cutting process, making the surface of the helmet more flat after processing, and improving the cutting accuracy; 4. After the cutting position of the helmet production cutting equipment is limited, the first motor is started to drive the moving gear to rotate. The moving gear rotates on the surface of the meshing fixed gear, driving the rotating column and the movable column to rotate in a circular motion in the inner annular groove and the outer annular groove. As a result, the connecting plate and the cutting blade also rotate, performing a circular cut on the helmet body. It can work continuously at a stable and fast rhythm, eliminating the need for manual operation one by one. It can complete more helmet burr removal tasks within a unit of time. As long as the equipment is properly maintained and powered, it can operate continuously for 24 hours, improving production efficiency. Operating according to the preset program and parameters also ensures that the position, depth, and accuracy of the burr removal of each helmet are highly consistent, increasing product consistency and maintaining a high yield rate.

The moving rod 24 automatically retracts into the fixed rod 32 according to the thickness and position of the helmet body 2, causing the spring 31 to retract under force. At this time, the multiple first rollers 28 and second rollers 34 limit different positions on the inner and outer walls of the helmet body 2, cooperating with the cutting disc 17 for stable cutting; When the second motor 25 is started, start the first motor 15 at the same time to drive the moving gear 21 to rotate. The moving gear 21 rotates on the surface of the meshing fixed gear 9, driving the support plate 8 and the connecting plate 14 to rotate and cut around the helmet body 2 synchronously by 360°. Thus, the multiple first rollers 28 and second rollers 34 rotate on the surface and inner wall of the helmet body 2. As the support plate 8 rotates, the rotating columns 19 in the two L-shaped plates 18 rotate at the same time. Subsequently, the rotating columns 19 rotate in a circular motion in the inner annular groove 12, and at the same time, the movable columns 20 rotate in a circular motion in the outer annular groove 13, enabling the device to cut and move smoothly; After cutting is completed, the support plate 8 and the connecting plate 14 return to their original positions, and the cut burrs fall. Start the third electric push rod 29 to push the push plate 30 upward, and the movable column 20 pushes the burrs upward. Reverse drive the first electric push rod 4 and the second electric push rod 22 to release the limit on the helmet body 2. Finally, take out the helmet body 2 and the burrs, and place the unprocessed helmet body 2 above the support rod 6 to repeat the operation.
