Description

Technical Field

[0001] The present invention relates to the technical field related to the production of bulletproof helmet linings, and specifically to a production device for bulletproof helmet linings with triple protection. Background Technique

[0002] A bulletproof helmet is a piece of equipment that can absorb and dissipate the energy of a bullet, prevent penetration, reduce blunt trauma, and effectively protect the human head. An inner lining layer is usually provided inside the bulletproof helmet to make it more comfortable for combatants to wear. During the production process of the bulletproof helmet lining, it is necessary to punch the manufactured lining fabric into a suitable shape for easy installation inside the bulletproof helmet.

[0003] During the existing process of punching the lining fabric of a bulletproof helmet, the lining fabric is prone to positional deviation before punching, which affects the punching effect of the punched fabric. Moreover, during punching, the punched fabric is easily stuck inside the punching die, making subsequent punching inconvenient. And after punching, a lot of small scraps are generated, making it inconvenient to separate the scraps from the punched lining fabric, which is rather troublesome. Therefore, we propose a production device for bulletproof helmet linings with triple protection to facilitate solving the problems raised above. Summary of the Invention

A baffle is fixedly installed on the lower surface of the screen.

[0007] Preferably, a rotating shaft is rotatably connected inside the support frame, and a cam is fixedly installed on the surface of the rotating shaft. The rotating shaft and the second rotating shaft are rotationally connected by a first belt.

[0008] Preferably, a coiling roller and a feeding roller are arranged inside the support frame. Rectangular bumps are fixedly installed on the surfaces at both ends of the coiling roller and the feeding roller. Connectors are arranged on both sides of the coiling roller and the feeding roller, and clamping grooves are formed on the surfaces of the two connectors. The connection mode between the rectangular bumps and the clamping grooves is clamping connection, and a clamping structure is formed between the coiling roller, the feeding roller and the connectors on both sides.

[0009] Preferably, a fixing block is fixedly installed inside the support frame, and the fixing block is arranged inside the conveyor belt.

[0010] Preferably, the incomplete gear and the connecting gear are both rotatably connected to the surface of the support frame, and the connection mode between the incomplete gear and the connecting gear is meshing connection. The first rotating shaft and the second rotating shaft are both rotatably connected inside the support frame, and the conveyor belt is in contact with the surfaces of the first rotating shaft and the second rotating shaft.

[0013] Preferably, a top plate is arranged inside the blanking die, and the top plate is slidably connected inside the blanking die, and a third spring is fixedly installed between the top plate and the blanking die.

[0014] Preferably, a sliding block is slidably connected inside the connector on one side of the coiling roller and the feeding roller, and a fourth spring is fixedly installed between the sliding block and the connector. The connector on the other side of the coiling roller and the second rotating shaft are rotationally connected by a second belt.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The production equipment for the triple-protection bulletproof helmet lining facilitates the fixation of the lining fabric during blanking, avoids the situation of fabric deviation, and can prevent the blanked fabric from getting stuck inside the blanking die. Moreover, it is convenient to separate the blanked scraps from the lining fabric, enhancing its practicality.

[0016] 1. By setting a fixed frame, a sliding frame, a second spring, rollers, and a connecting belt, the fixed frame is slidably connected to the sliding frame, and the second spring is installed between the fixed frame and the sliding frame. The elastic force of the second spring drives the sliding frame and the internal rollers and connecting belt to move downward, pressing the connecting belt against the surface of the lining fabric to fix the fabric. When the conveyor belt conveys the lining fabric, the connecting belt is driven by the friction force of the fabric, which can prevent the fabric from deviating during the conveying process, affecting the blanking effect of the fabric, and enhancing its practicality.

By setting a rotating disk, a connecting rod, a blanking die, a first spring, and a top plate, one end of the connecting rod is rotatably connected to one side of the surface of the rotating disk, and the other end of the connecting rod is hinged to the moving block. By starting the second motor to drive the rotating disk to rotate, the rotating disk drives the moving block and the blanking die to move up and down reciprocally through the connecting rod on the surface, blanking the lining fabric. When the blanking die moves downward for blanking, the top plate first contacts the fabric and deforms the first spring. When the blanking die moves upward after blanking, the elastic force of the first spring drives the top plate to move, and the top plate will eject the fabric in the blanking die, preventing it from remaining in the blanking die and affecting the blanking on the lower side, enhancing its practicality.

[0018] 3. By setting a rotating shaft, a cam, a fixed strip, a sieve mesh, and a baffle, the rotating shaft and the second rotating shaft are rotationally connected through a first belt. The sieve mesh is slidably connected within the fixed strip, and a third spring is installed on one side. When the second rotating shaft drives the cam to rotate, the cam strikes the baffle, and the baffle drives the sieve mesh to slide within the fixed strip. The elastic force of the third spring drives the sieve mesh to slide within the fixed strip, cooperating with the cam to make the sieve mesh move back and forth reciprocally, separating the blanked scraps from the lining fabric, facilitating collection, and enhancing its practicality.

[0019] 4. By setting a connecting piece, a sliding block, and a fourth spring, the connecting piece on the other side of the coiling roller is rotationally connected to the second rotating shaft through a second belt, facilitating driving the coiling roller to rotate through the connecting piece to collect the remaining corner scraps after blanking. And the sliding block is slidably connected inside one of the connecting pieces, and the fourth spring is installed between the sliding block and the connecting piece, facilitating the replacement of the coiling roller and the unwinding roller, enhancing its practicality.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figure 1-4 , the present invention provides a technical solution: a production device for a triple-protection bulletproof helmet lining, including a bottom plate 1. To prevent the cut fabric from getting stuck inside the punching die 17, a support frame 2 is fixedly installed on the surface of the bottom plate 1, and a first motor 3 is fixedly installed on the inner surface of the support frame 2. The output end of the first motor 3 is connected to an incomplete gear 5, and a connecting gear 6 is connected to the surface of the incomplete gear 5. A first rotating shaft 7 is fixedly installed on one side of the connecting gear 6, and a second rotating shaft 8 is arranged on one side of the first rotating shaft 7. A conveyor belt 9 is arranged on the surfaces of the first rotating shaft 7 and the second rotating shaft 8. The incomplete gear 5 and the connecting gear 6 are both rotatably connected to the surface of the support frame 2, and the connection between the incomplete gear 5 and the connecting gear 6 is a meshing connection. The first rotating shaft 7 and the second rotating shaft 8 are both rotatably connected inside the support frame 2, and the conveyor belt 9 is in contact with the surfaces of the first rotating shaft 7 and the second rotating shaft 8, facilitating the intermittent movement of the conveyor belt 9 driven by the incomplete gear 5. A fixing block 10 is fixedly installed inside the support frame 2, and the fixing block 10 is arranged inside the conveyor belt 9, facilitating the protection of the conveyor belt 9 by setting the fixing block 10 to avoid damage to the surface of the conveyor belt 9 caused by long-term punching. An installation box 11 is fixedly installed on the surface of the support frame 2, and a driving box 12 is installed on the top of the installation box 11. A fixing plate 18 is fixedly installed inside the driving box 12, and a second motor 13 is fixedly installed on the surface of the fixing plate 18. The output end of the second motor 13 is fixedly connected to a rotating disk 14, and a connecting rod 15 is connected to the surface of the rotating disk 14. One end of the connecting rod 15 is connected to a moving block 16. One end of the connecting rod 15 is rotatably connected to one side of the surface of the rotating disk 14, and the connection between the other end of the connecting rod 15 and the moving block 16 is a hinged connection. The moving block 16 is connected to the driving box 12 by a sliding connection method, facilitating the up and down movement of the moving block 16 driven by the rotation of the rotating disk 14. The moving block 16 is limited by the driving box 12, and a punching die 17 is fixedly installed on the lower surface of the moving block 16. A top plate 19 is arranged inside the punching die 17, and the top plate 19 is slidably connected inside the punching die 17. A third spring 39 is fixedly installed between the top plate 19 and the punching die 17, facilitating the movement of the top plate 19 driven by the elastic force of the third spring 39 to eject the lining fabric inside the punching die 17 and avoid the situation where the cut fabric gets stuck inside the punching die 17.

[0033] Please refer to Figure 2 and Figure 5, To facilitate the fixation of the lining fabric, fixing frames 20 can be fixedly installed on the inner wall surfaces of both sides of the installation box 11. A sliding frame 21 is slidably connected inside the fixing frame 20. A second spring 22 is fixedly installed between the top of the sliding frame 21 and the inside of the fixing frame 20. Two rollers 23 are rotatably connected inside the sliding frame 21, and the two rollers 23 are connected by a connecting belt 24. The connecting belt 24 is attached to the surfaces of the two rollers 23. It is convenient to drive the sliding frame 21 to slide downward inside the fixing frame 20 by the elastic force of the second spring 22, driving the internal connecting belt 24 to press on the surface of the lining fabric, preventing the fabric from moving during transportation.

[0034] Please refer to Figures 6-10 , To facilitate the separation of the lining fabric and the scraps and the installation and replacement of the coiling roller 32 and the unwinding roller 33, a rotating shaft 25 can be rotatably connected inside the support frame 2. A cam 26 is fixedly installed on the surface of the rotating shaft 25. The rotating shaft 25 and the second rotating shaft 8 are rotationally connected by a first belt 27, facilitating the rotation of the rotating shaft 25 by the first belt 27. Fixed strips 28 are fixedly installed on both sides of the inner wall of the support frame 2, and the fixed strips 28 are inclined. A sieve 29 is slidably connected inside the fixed strips 28. A first spring 30 is fixedly installed between the sieve 29 and the inside of the fixed strips 28. A baffle 31 is fixedly installed on the lower surface of the sieve 29, facilitating the cam 26 to strike the baffle 31, driving the sieve 29 to move inside the fixed strips 28 and, in cooperation with the first spring 30, driving the sieve 29 to move to the other side, causing the sieve 29 to shake, separating the lining fabric and the punched scraps and collecting them. A coiling roller 32 and an unwinding roller 33 are arranged inside the support frame 2. Rectangular protrusions 36 are fixedly installed on the surfaces at both ends of the coiling roller 32 and the unwinding roller 33. Connectors 34 are arranged on both sides of the coiling roller 32 and the unwinding roller 33. Card slots 37 are formed on the surfaces of the two connectors 34. The connection mode between the rectangular protrusions 36 and the card slots 37 is snap connection, and the coiling roller 32 and the unwinding roller 33 and the connectors 34 on both sides form a snap structure. A sliding block 38 is slidably connected inside the connector 34 on one side of the coiling roller 32 and the unwinding roller 33, and a fourth spring 4 is fixedly installed between the sliding block 38 and the connector 34. The connector 34 on the other side of the coiling roller 32 and the second rotating shaft 8 are rotationally connected by a second belt 35. Insert the rectangular protrusion 36 on one side of the coiling roller 32 and the unwinding roller 33 into the card slot 37. At this time, the rectangular protrusion 36 drives the sliding block 38 to move, aligning the rectangular protrusion 36 on the other side of the coiling roller 32 and the unwinding roller 33 with the card slot 37 on the surface of the connector 34 on the other side. Drive the coiling roller 32 and the unwinding roller 33 to move by the elastic force of the fourth spring 4, and insert the rectangular protrusion 36 on the other side into the card slot 37, facilitating the installation and replacement of the coiling roller 32 and the unwinding roller 33.

[0035] Working principle: First, when in use, the material feeding roller 33 and the coiling roller 32 are clamped between two connecting pieces 34. One end of the fabric is passed through the bottom of the connecting belt 24 and fixedly connected to the coiling roller 32 on the lower side of the conveyor belt 9. The elastic force of the second spring 22 drives the sliding frame 21 to slide inside the fixed frame 20. The sliding frame 21 drives the internal rollers 23 and the connecting belt 24 to move downward, pressing the connecting belt 24 against the surface of the lining fabric to fix the fabric. When the conveyor belt 9 conveys the lining fabric, the connecting belt 24 is driven to move by the friction force of the fabric.

[0036] Start the first motor 3 to drive the incomplete gear 5 to rotate. The incomplete gear 5 drives the first rotating shaft 7 to perform intermittent motion through the connecting gear 6 on its surface. While the first rotating shaft 7 is rotating, it drives the conveyor belt 9 to perform intermittent motion through the second rotating shaft 8 to convey the lining fabric on the surface. Start the second motor 13 to drive the rotating disk 14 on its surface to rotate. While the rotating disk 14 is rotating, it drives the moving block 16 and the punching die 17 to perform reciprocating up and down motion through the connecting rod 15 on its surface, cooperating with the intermittent motion of the conveyor belt 9. When the conveyor belt 9 stops moving, the punching die 17 moves downward to punch the fabric. During the punching process when the punching die 17 moves downward, the top plate 19 contacts the fabric and drives the first spring 30 to deform. When the punching die 17 moves upward, the elastic force of the first spring 30 drives the top plate 19 inside the die to eject the lining fabric, preventing the lining fabric after punching from remaining inside the punching die 17 and affecting the next punching.

[0037] The lining fabric after punching and the scraps generated by punching both fall on the surface of the conveyor belt 9. The conveyor belt 9 transports them to the surface of the sieve 29. While the second rotating shaft 8 is rotating, it drives the connecting piece 34 and the coiling roller 32 on one side to move through the second belt 35 to wind and collect the cut-off scraps. The first belt 27 drives the rotating shaft 25 to rotate. The rotating shaft 25 drives the cam 26 to rotate. The cam 26 hits the baffle 31. The baffle 31 drives the sieve 29 to slide inside the fixed strip 28. The elastic force of the third spring 39 drives the sieve 29 to slide inside the fixed strip 28, cooperating with the cam 26 to make the sieve 29 reciprocate back and forth to separate the scraps and the lining fabric after punching for convenient collection. The sliding block 38 is slidably connected inside one connecting piece 34, and the fourth spring 4 is installed between the sliding block 38 and the connecting piece 34 to facilitate the replacement of the coiling roller 32 and the material feeding roller 33. The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
