Description

Technical Field

[0001] This invention relates to the field of polystyrene board nailing technology, specifically to an automated polystyrene board nailing machine. Background Technology

[0002] Existing polystyrene board nailing machines generally use a multi-axis motion mechanism in conjunction with a positioning cylinder to perform nailing, or they directly push the nail into a fixed position. The nailing method of the multi-axis motion mechanism requires adjusting multiple memory positions, so that the corresponding multi-axis motion mechanism can find the corresponding nail position. If the nail position needs to be changed, a lot of time is required for machine debugging, which is cumbersome and unsuitable for high-efficiency nailing scenarios. On the other hand, the nailing method of directly pushing the nail into a fixed position will cause stress concentration at the nailing position, causing the polystyrene board to deform towards the nailing position, and the deformation is greatest at the nailing position, resulting in poor nailing effect.

[0003] Chinese Patent CN210501499U discloses an automatic nail-threading machine, which realizes the function of multi-station operation of the nail-threading machine, thereby improving the working efficiency and convenience of the nail-threading machine. However, it is quite cumbersome to perform a lot of debugging on the sensors, touch screen and microcontroller, and to change the nail-threading position of the polystyrene board.

[0004] Chinese patent CN109732028A discloses a rivet-threading machine. By cooperating with the rivet support block and the guide groove, rivets can be quickly sorted into the rivet-threading station, then positioned by the positioning mechanism, and finally threaded by the rivet-threading mechanism. It has a high degree of automation, reduces labor costs, and improves production efficiency. However, it requires control by a multi-axis motion mechanism and has many memory positions, making it unsuitable for high-efficiency rivet-threading work scenarios.

[0005] Therefore, how to develop a nail-driving machine that integrates stress reduction to stabilize nail insertion, has high working efficiency, and is suitable for nail insertion position changes has become a problem to be solved. Summary of the Invention

[0006] The purpose of this invention is to provide a polystyrene board nailing machine to solve the above problems.

[0007] To achieve the above objectives, the following technical solutions are provided:

[0008] A polystyrene board nailing machine, used in conjunction with polystyrene boards and nails, includes: a frame, a conveying mechanism, a nail-carrying mechanism, and a nail-piercing mechanism. The frame includes a track frame and a platform frame. The track frame is a frame structure symmetrically arranged on both sides of the platform frame. The track frame adjustably supports the conveying mechanism and the nail-carrying mechanism. The top surface of the platform frame is a plate-like structure used to fix and support the nail-piercing mechanism. The conveying mechanism extends perpendicular to the length direction of the frame. The polystyrene board is transported by the conveying mechanism. The nail-carrying mechanism is located close to the conveying mechanism, and an opening is provided on the side of the nail-carrying mechanism adjacent to the conveying mechanism, so that the polystyrene board nails can be inserted into the polystyrene board on the conveying mechanism through the opening. The nail-piercing mechanism includes a first cylinder, a movable plate, and a connecting plate. The connecting plate may or may not penetrate the movable plate. The nail-piercing mechanism can perform pushing and / or nailing operations on the polystyrene board according to the connection relationship between the movable plate and the connecting plate.

[0009] Preferably, the conveying mechanism includes a chain guide rail, a chain, and baffles. The chain is disposed on the chain guide rail, and the end of the chain away from the chain guide rail is bent and provided with a folded lug. The folded lug extends in a direction away from the center line of the chain, and baffles are provided on the folded lug at fixed intervals for pushing the polystyrene board to move on the conveying mechanism.

[0010] Preferably, the width of the chain guide rail is smaller than the width of the polystyrene board, the length between two adjacent baffles is greater than the length of the polystyrene board, and the polystyrene board can be elastically deformed on the conveying mechanism, thereby facilitating the insertion of the polystyrene board nail into the polystyrene board.

[0011] Preferably, the width of the chain guide rail and the length between two adjacent baffles can be varied according to the Poisson's ratio of different polystyrene boards.

[0012] Preferably, the nail-carrying mechanism includes nail-carrying guide rails and a second cylinder symmetrically arranged with the nail-piercing mechanism as the central axis. The two nail-carrying guide rails are also symmetrically provided with nail-piercing grooves on their adjacent sides. One end of the nail-piercing groove is fixed to the nail-piercing mechanism, and the other end of the nail-piercing groove is open and connected to the conveying mechanism.

[0013] Preferably, the polystyrene board nail is disposed on the nail-carrying guide rail, and the second cylinder can reciprocate at a constant speed along the nail-carrying guide rail, thereby conveying the polystyrene board nail from the nail-carrying guide rail to the nail-passing groove.

[0014] Preferably, the first cylinder of the nail-piercing mechanism is fixed to the platform frame, and a top block is fixedly connected to the pushing end of the first cylinder. One end of the connecting plate is fixed to the top block, and the other end of the connecting plate can be fixed to one side wall of the movable plate. The other end of the connecting plate can also penetrate the movable plate and slide relative to it. When the connecting plate penetrates the movable plate, the end of the connecting plate that penetrates the movable plate extends towards the opening of the nail-piercing groove. Thus, the connecting plate can push the polystyrene board nail into the polystyrene board for the nail-piercing process. When the connecting plate is fixed to the movable plate, the first cylinder can push the movable plate, thereby performing a pressing process on the polystyrene board.

[0015] Preferably, the automated polystyrene board nailing machine includes at least one nailing mechanism for performing the pushing and nailing processes, and the nailing mechanisms for performing different processes are symmetrically arranged at both ends of the platform frame.

[0016] Preferably, the benzene plate is offset toward the nail-piercing mechanism that performs the pressing process, and the movable plate of the nail-piercing mechanism that performs the pressing process abuts against the chain guide when it reaches its maximum stroke.

[0017] Preferably, the nail-piercing mechanism that performs different processes first pushes the polystyrene board and then performs the nail-piercing process.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. This invention can combine the two processes of pressing and nailing into one process by different connection settings of the nailing mechanism, or it can set the two processes of pressing and nailing separately. At the same time, the pressing process and the nailing process have the same structure, and the conversion between the pressing process and the nailing process can be realized by changing different connection settings. In addition, it can be flexibly changed according to the need for nailing at different positions of the polystyrene board.

[0020] 2. The adjacent baffles and chain guide rails of the present invention are used to fix the polystyrene board. The polystyrene board has a certain range of motion in the length direction and protrudes outward in the width direction. At this time, the pushing process can push the polystyrene board according to the width of the chain guide rail. At this time, the part of the polystyrene board that exceeds the chain guide rail is neatly pushed and compressed, and the chain guide rail limits the pushing stroke to ensure that the polystyrene board is not damaged by excessive pushing.

[0021] 3. During the process of pushing and squeezing the polystyrene board of the present invention, its width direction is compressed and its length direction is correspondingly stretched according to its Poisson's ratio. According to the different Poisson's ratios of different polystyrene boards, the area where the polystyrene board is fixed can be relatively changed, thereby conforming to the Poisson's ratio of the polystyrene board, which facilitates the compression and nailing operation of the polystyrene board.

[0022] 4. The second cylinder of the present invention performs reciprocating motion to push the polystyrene board nails scattered on the nail guide rail into the nail slot in sequence. The reciprocating motion speed of the second cylinder is higher than the speed at which the conveying mechanism conveys the polystyrene board to the nail position. Therefore, when the polystyrene board reaches the nail position, there are always polystyrene board nails in the nail slot, which facilitates the nailing operation.

[0023] 5. In this invention, the benzene plate is biased towards the nail-piercing mechanism performing the pressing process and is located at one end of the conveying mechanism. When the benzene plate travels through the conveying mechanism to the symmetrically arranged nail-piercing mechanisms of different processes, the first cylinder on the nail-piercing mechanism performing the pressing process drives the movable plate. The movable plate squeezes the benzene plate that exceeds the chain guide rail and neatly presses it towards one side of the nail-piercing groove. At this time, the first cylinder on the nail-piercing mechanism performing the nail-piercing process drives the connecting plate. The connecting plate slides parallel to its corresponding movable plate. The benzene plate nail pushed by the second cylinder in the nail-piercing groove is pushed by the connecting plate and passes through the opening of the nail-piercing groove into the benzene plate that is squeezed into the nail-piercing groove, completing the nail-piercing operation of the benzene plate. The nail-piercing mechanism returns to its original position, and the benzene plate elastically deforms back to its original unpressed state, completing the nail-piercing operation. The conveying mechanism then sends the nail-pierced benzene plate away from the device. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the structural schematic diagrams in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figure 1-6 As shown, the automated polystyrene board nailing machine, used in conjunction with polystyrene boards and nails, includes: a frame 10, a conveying mechanism 20, a nail-carrying mechanism 30, and a nail-threading mechanism 40. The frame 10 includes a track frame 101 and a platform frame 102. The track frame 101 is a frame structure symmetrically arranged on both sides of the platform frame 102. The track frame 101 adjustably supports the conveying mechanism 20 and the nail-carrying mechanism 30. The top surface of the platform frame 102 is a plate-like structure used to fix and support the nail-threading mechanism 40. The conveying mechanism 20 extends perpendicular to the length direction of the frame 10. The polystyrene boards are transported through the conveying mechanism 20. The nail-carrying mechanism 30 is located close to the conveying mechanism 20, and an opening is provided on the side of the nail-carrying mechanism 30 adjacent to the conveying mechanism 20, thus nailing the polystyrene boards. The pinning mechanism 40, which inserts into the polystyrene sheet on the conveying mechanism 20 through the opening, includes a first cylinder 401, a movable plate 402, and a connecting plate 403. The connecting plate 403 may or may not be connected to the movable plate 402. The pinning mechanism 40 can perform pushing and / or pinning operations on the polystyrene sheet according to the connection relationship between the movable plate 402 and the connecting plate 403. Through different connection settings of the pinning mechanism 40, the two operations of pushing and pinning can be combined into one operation, or the two operations of pushing and pinning can be set separately. At the same time, the pushing operation and the pinning operation have the same structure. The conversion between the pushing operation and the pinning operation can be achieved by changing different connection settings. Thus, it can be flexibly changed according to the need for pinning at different positions on the polystyrene sheet.

[0033] In some embodiments, the conveying mechanism 20 includes a chain guide rail 201, a chain 202, and baffles 203. The chain 202 is disposed on the chain guide rail 201. One end of the chain 202 away from the chain guide rail 201 is bent and provided with a folded ear 204. The folded ear 204 extends in a direction away from the center line of the chain 202. Baffles 203 are provided on the folded ear 204 at fixed intervals for pushing the polystyrene board to move on the conveying mechanism 20.

[0034] In some embodiments, the width of the chain guide 201 is smaller than the width of the polystyrene board, and the length between two adjacent baffles 203 is greater than the length of the polystyrene board. The polystyrene board can be elastically deformed on the conveying mechanism 20, which facilitates the insertion of the polystyrene board nail into the polystyrene board. The adjacent baffles 203 and the chain guide 201 are used to fix the polystyrene board. The polystyrene board has a certain range of motion in the length direction and protrudes outward in the width direction. At this time, the pressing process can press the polystyrene board according to the width of the chain guide 201. At this time, the part of the polystyrene board that exceeds the chain guide 201 is neatly pushed and compressed, and the chain guide 201 limits the pressing stroke to ensure that the polystyrene board is not damaged by excessive pressing.

[0035] In some embodiments, the width of the chain guide 201 and the length between two adjacent baffles 203 can vary according to the Poisson's ratio of different polystyrene boards; during the process of the polystyrene board being pushed and squeezed, its width direction is compressed, and its length direction is correspondingly stretched according to its Poisson's ratio. According to the different Poisson's ratios of different polystyrene boards, the area where the polystyrene board is fixed can vary relatively, thereby conforming to the Poisson's ratio of the polystyrene board, which facilitates the compression and pinning operation of the polystyrene board.

[0036] In some embodiments, the nail-carrying mechanism 30 includes nail-carrying guide rails 301 and a second cylinder 302 symmetrically arranged with the nail-piercing mechanism 40 as the central axis. The two nail-carrying guide rails 301 are also symmetrically provided with nail-piercing grooves 303 on the side close to each other. One end of the nail-piercing groove 303 is fixed to the nail-piercing mechanism 40, and the other end of the nail-piercing groove 303 is open and connected to the conveying mechanism 20. The opening of the nail-piercing groove 303 leaves a position for a polystyrene board nail in the conveying mechanism 20, so that the polystyrene board on the conveying mechanism 20 can be nailed through the opening.

[0037] In this embodiment, the second cylinder 302 performs a reciprocating motion to push the polystyrene board nails scattered on the nail guide rail 301 into the nail insertion groove 303 in sequence. The reciprocating motion rate of the second cylinder 302 is higher than the rate at which the conveying mechanism 20 conveys the polystyrene board to the nail insertion position. Therefore, when the polystyrene board reaches the nail insertion position, there are always polystyrene board nails in the nail insertion groove 303.

[0038] In some embodiments, the polystyrene board nails are disposed on the nail conveying guide rail 301, and the second cylinder 302 can reciprocate at a constant speed along the nail conveying guide rail 301, thereby conveying the polystyrene board nails from the nail conveying guide rail 301 to the nail slot 303; the second cylinder 302 can be adjusted to a slow reciprocating speed, thereby adding polystyrene board nails to the nail conveying guide rail 301 at any time, facilitating the transportation of polystyrene board nails;

[0039] In some embodiments, the first cylinder 401 of the nail-piercing mechanism 40 is fixed to the platform frame 102. The pushing end of the first cylinder 401 is fixedly connected to the top block 404. One end of the connecting plate 403 is fixed to the top block 404. The other end of the connecting plate 403 can be fixed to one side wall of the movable plate 402. The other end of the connecting plate 403 can also pass through the movable plate 402 and slide relative to it. When the connecting plate 403 is set through the movable plate 402, the end of the connecting plate 403 that passes through the movable plate 402 extends towards the opening direction of the nail-piercing groove 303. Then the connecting plate 403 can push the polystyrene board nail into the polystyrene board to perform the nail-piercing process. When the connecting plate 403 is fixed to the movable plate 402, the first cylinder 401 can push the movable plate 402, thereby performing the pressing process on the polystyrene board.

[0040] In some embodiments, the automated polystyrene board nailing machine includes at least one set of nailing mechanisms 40 for performing the pushing and nailing processes, and the nailing mechanisms 40 for performing different processes are symmetrically arranged at both ends of the platform frame 102. When the polystyrene board is in place, the symmetrically arranged nailing mechanisms 40 can push it first, so that the polystyrene board is compressed, and then nail it. This facilitates the insertion of the nails into the polystyrene board and will not cause damage to the polystyrene board.

[0041] In some embodiments, the polystyrene board is offset toward the nail-threading mechanism 40 that performs the pressing process. When the movable plate 402 of the nail-threading mechanism 40 reaches its maximum stroke, it abuts against the chain guide rail 201. When the maximum stroke of the pressing process reaches the chain guide rail 201, the pressing process is in place and ready to return to its original position to prevent the polystyrene board from being squeezed and damaged.

[0042] In some embodiments, the nailing mechanism 40, which performs different processes, first pushes the polystyrene board and then performs the nailing process.

[0043] In this embodiment, the benzene plate is biased towards the nail-piercing mechanism 40 performing the pressing process and is disposed at one end of the conveying mechanism 20. When the benzene plate moves through the conveying mechanism 20 to the symmetrically arranged nail-piercing mechanisms 40, the first cylinder 401 on the nail-piercing mechanism 40 performing the pressing process drives the movable plate 402. The movable plate 402 squeezes the benzene plate that exceeds the chain guide rail 201 and neatly presses it towards one side of the nail-piercing groove 303. At this time, the first cylinder 401 on the nail-piercing mechanism 40 performing the nail-piercing process... The cylinder 401 drives the connecting plate 403, which slides parallel to its corresponding movable plate 402. The benzene plate nail pushed by the second cylinder 302 in the nail slot 303 is pushed by the connecting plate 403 and passes through the opening of the nail slot 303 into the benzene plate that is squeezed into the nail slot 303, completing the nailing operation of the benzene plate. The nailing mechanism 40 returns to its original position, and the benzene plate elastically deforms back to its original un-squeezed state, completing the nailing operation. The conveying mechanism 20 sends the nailed benzene plate away from the device.
