Description

Technical Field

[0001] The present invention belongs to the technical field of machinery, and relates to a nailing device, in particular to a spring mattress border nailing device. Background Art

[0002] A spring mattress is commonly known as a "Simmons" mattress, which is a commonly used and relatively high-performance modern mattress. Its cushion core is composed of a spring layer and two hard cotton felt layers respectively laid flat on the top and bottom surfaces of the spring layer. Among them, the top edge and the bottom edge of the spring layer are both circular frames, and a nail gun is used to fasten the circular frame and the hard cotton felt layer together.

[0003] To achieve automatic nailing of the nail gun to liberate human labor, people have invented automated devices. For example, a mattress bed net border fixing device (application number: 202320128476.8) disclosed in the Chinese patent database includes a translation base. A lifting guide seat is vertically installed on the upper surface of the translation base. An upper nailing structure is vertically slidably installed on the lifting guide seat, and a lower nailing structure is fixedly installed. Both the upper nailing structure and the lower nailing structure include a mounting substrate. A U-shaped nail roll is rotatably installed on the mounting substrate. A U-shaped nail tape is wound around the U-shaped nail roll. A bottom support plate for lifting the U-shaped nail tape is fixedly installed between the U-shaped nail roll and the mounting substrate. A side baffle for guiding the U-shaped nail tape to one side is fixedly installed on the bottom support plate. A nailer is provided on the side of the mounting substrate away from the U-shaped nail roll, and a nail feeding guide rail extending above the bottom support plate is provided on the nailer.

[0004] When the above device is in use, the nailing structure tilts and moves under the action of a cylinder for nailing operations. Limited by processing accuracy and spring material, in actual processing, there are more or less certain thickness errors in spring layers of the same specification, resulting in certain undulations in the position of the above circular frame. In the above device, for mattresses of the same specification, the relative height of the nailing structure is fixed and unchanged, and there is a situation where it cannot be completely fastened, affecting the processing quality and accuracy. Summary of the Invention

[0005] The object of the present invention is to address the above problems existing in the prior art and propose a spring mattress border nailing device with stable operation.

[0006] The object of the present invention can be achieved by the following technical solutions: A spring mattress border nailing device, including a bracket, a base, a positioning seat, and a nail gun disposed obliquely downward. An elevating mechanism for driving the base to move up and down is provided on the bracket. The rear end of the nail gun is installed on the positioning seat. A driving mechanism for driving the positioning seat to move back and forth to make the muzzle of the nail gun approach or move away from the mattress border is provided on the base. It is characterized in that a straight sheet body is provided on the left side of the nail gun. The rear end of the straight sheet body is hinged to the positioning seat through a horizontally arranged rotating shaft, and the axis of the rotating shaft extends left and right. The front end of the straight sheet body is in front of the nail gun, and the front end of the straight sheet body can press on the top wall of the mattress border; A sensor is also fixed above the front end of the straight sheet body on the positioning seat. The sensor controls the closing of the elevating mechanism and the opening of the driving mechanism by contacting the front end of the straight sheet body.

[0007] The usage process is as follows: In the initial state, the straight sheet body is inclined under its own gravity; during operation, the elevating mechanism drives the base to move downward. When the front end of the straight sheet body contacts the top wall of the mattress border, it will swing upward and press on the sensor. At this time, the elevating mechanism closes, and the driving mechanism works to perform the nailing operation.

[0008] With the cooperation of the swingable straight sheet body and the sensor, the nailing height of the nail gun can be corrected by the contact between the front end of the straight sheet body and the mattress border, ensuring that each nail is driven in the correct position, and the working stability and processing accuracy are both good.

[0009] In the above spring mattress border nailing device, the positioning seat includes a main body and a seat body slidably arranged horizontally back and forth on the main body. The driving mechanism and the nail gun are both connected to the main body. The above-mentioned straight sheet body and sensor are both connected to the seat body. A vertical plane is formed on the front side of the seat body. A spring is also provided on the main body to make the seat body have a tendency to move forward so that the vertical plane presses on the side wall of the mattress border. Specifically in use, the vertical plane presses on the hard cotton felt of the mattress border. When the nail gun moves forward to perform the nailing action, the seat body moves backward against the spring force to strengthen the pressing on the hard cotton felt to make it stably positioned, ensuring that the hard cotton felt does not deviate during the nailing process, thereby further improving the working stability and accuracy.

[0010] In the above spring mattress border nailing device, a strip-shaped groove for accommodating the straight sheet body is horizontally penetrated at the position of the vertical plane on the seat body. The strip-shaped groove includes two groove walls arranged side by side up and down, and the front end of the straight sheet body extends out of the strip-shaped groove. The design of the strip-shaped groove is used to shorten the swing stroke of the straight sheet body, making the overall reaction more efficient and improving the processing efficiency.

[0011] In the above spring mattress border nailing device, the front side of the seat body further includes a guiding plane arranged obliquely upward relative to the nail gun. The guiding plane is below the vertical plane, and the guiding plane and the vertical plane are in arc transition. With the above design, when the base moves downward, the vertical plane can smoothly move downward to contact the side wall of the mattress border, and the working stability is better.

[0012] In the above-mentioned spring mattress border nailing device, a first linear guide is horizontally fixed on the main body. The first linear guide is located above the straight sheet body, and the length of the first linear guide extends back and forth. A first guide block is installed on the first linear guide, and the upper side of the seat body is fixedly connected to the first guide block. The cooperation of the first linear guide and the first guide block realizes the sliding connection between the seat body and the main body, which has the advantages of simple structure and stable operation.

[0013] In the above-mentioned spring mattress border nailing device, a screw is horizontally fixed on the main body. The screw and the first linear guide are in the same length direction. A spring is sleeved on the screw rod part, and the two ends of the spring act on the rear side of the seat body and the main body respectively. The screw is used for both spring positioning and spring expansion and contraction guiding. While simplifying the structure, it can improve the working stability.

[0014] In the above-mentioned spring mattress border nailing device, the type of the sensor is a proximity switch. The proximity switch includes a straight rod-shaped body, and the body is vertically fixed on the main body.

[0015] In the above-mentioned spring mattress border nailing device, the driving mechanism includes a connecting seat, a first motor, and a front connecting rod, a driven connecting rod, a driving connecting rod, and a rear connecting rod arranged in sequence from front to back; the upper and lower ends of the rear connecting rod and the upper and lower ends of the driving connecting rod are respectively hinged to the connecting seat and the base through a horizontally arranged rear shaft, the upper ends of the front connecting rod and the driven connecting rod are respectively hinged to the connecting seat through a horizontally arranged front shaft, and the lower ends of the front connecting rod and the driven connecting rod are fixedly connected to the main body; the first motor is fixed on the base, and the first motor drives the rear shaft connected to the lower end of the driving connecting rod to rotate through a gear transmission structure. A first small gear is fixed on the rear shaft connected to the upper end of the driving connecting rod and the front shaft connected to the driven connecting rod, and the two first small gears are meshed; the axes of the front shaft and the rear shaft extend left and right.

[0016] The connecting rod assembly composed of the front connecting rod, the driven connecting rod, the driving connecting rod, and the rear connecting rod, while effectively increasing the stroke of the nail gun to adapt to different sizes of mattresses, makes the overall structure more compact, so as to effectively shorten the horizontal length of the device when it is not working and reduce the space occupation.

[0017] In the above-mentioned spring mattress border nailing device, the gear transmission structure includes a large gear fixed on the rear shaft connected to the lower end of the driving connecting rod and a second small gear fixed on the main shaft of the motor, and the second small gear is meshed with the large gear.

[0018] In the above-mentioned spring mattress border nailing device, the lifting mechanism includes a second motor fixed on the bracket, and the second motor is connected to the base through a lead screw nut transmission mechanism.

[0019] In the above-mentioned spring mattress border nailing device, the base is slidably connected to the bracket up and down to improve the sliding accuracy and stability of the base, and effectively ensure the accuracy of the nail gun nailing height correction.

[0020] In the above spring mattress border nailing device, a second linear guide is vertically fixed on the bracket, a second guide block is installed on the second linear guide, and the rear side of the base is fixedly connected to the second guide block.

[0021] Compared with the prior art, the spring mattress border nailing device has the following advantages:

[0022] 1. With the cooperation of the swing - arranged straight sheet body and the sensor, the height of the nail gun for nailing can be corrected by the contact between the front end of the straight sheet body and the mattress border, ensuring that each nailing is at the correct position, and both the working stability and the processing accuracy are relatively good.

[0023] 2. During specific use, the vertical plane presses on the hard cotton felt of the mattress border. When the nail gun moves forward for nailing, the seat body moves backward against the spring force to strengthen the extrusion of the hard cotton felt so that it is stably positioned, ensuring that the hard cotton felt does not deviate during the nailing process, thereby further improving the working stability and accuracy.

[0024] 3. The connecting rod assembly composed of the front connecting rod, the driven connecting rod, the driving connecting rod and the rear connecting rod, while effectively increasing the stroke of the nail gun to adapt to mattresses of different sizes, makes the overall structure more compact, effectively shortening the horizontal length of the device when it is not working and reducing the space occupation.

[0030] The following are specific embodiments of the present invention. In combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments. Embodiment 1

[0031] As Figure 1 shown, this spring mattress border nailing device includes a bracket 1, a base 2, a positioning seat 3, and a nail gun 4 disposed obliquely downward. Among them, the nail gun 4 is of an existing structure and can be obtained in the market.

[0032] Specifically,

[0033] The bracket 1 is provided with a lifting mechanism for driving the base 2 to lift and lower; the front end of the nail gun 4 is the muzzle, the rear end of the nail gun 4 is installed on the positioning seat 3, and the base 2 is provided with a driving mechanism for driving the positioning seat 3 to move forward and backward so that the muzzle of the nail gun 4 approaches or moves away from the mattress border.

[0034] As Figure 1 and Figure 2 shown, a straight piece 5 is provided on the left side of the nail gun 4, and the straight piece 5 has a certain weight. Among them, the rear end of the straight piece 5 is hinged to the positioning seat 3 through a horizontally arranged rotating shaft 6, and the axis of the rotating shaft 6 extends left and right; the front end of the straight piece 5 is in front of the nail gun 4, that is, relative to the nail gun 4, the straight piece 5 is closer to the mattress border, and in actual use, the front end of the straight piece 5 can press on the top wall of the mattress border. A sensor 7 is further fixed above the front end of the straight piece 5 on the positioning seat 3, and the sensor 7 controls the closing of the lifting mechanism and the opening of the driving mechanism by contacting the front end of the straight piece 5.

[0035] The usage process is as follows: In the initial state, the straight piece 5 is inclined under its own gravity; during operation, the lifting mechanism drives the base 2 to move downward. When the front end of the straight piece 5 contacts the top wall of the mattress border, it will swing upward and press on the sensor 7. At this time, the lifting mechanism closes, and the driving mechanism works for nailing operation.

[0036] With the cooperation of the swingable straight piece 5 and the sensor 7, the nailing height of the nail gun 4 is corrected by the contact between the front end of the straight piece 5 and the mattress border, ensuring that each nail is driven at the correct position, and both the working stability and the processing accuracy are relatively good.

[0037] Further explanation,

[0038] The positioning base 3 includes a main body 3a and a base body 3b that is horizontally slidable back and forth on the main body 3a. Among them, the driving mechanism and the nail gun 4 are both connected to the main body 3a; the straight piece 5 and the sensor 7 are both connected to the base body 3b. A vertical plane 3c is formed on the front side of the base body 3b, and a spring 8 is further provided on the main body 3a to make the base body 3b have a tendency to move forward so that the vertical plane 3c presses against the side wall of the mattress frame. During specific use, the vertical plane 3c presses against the hard cotton felt on the mattress frame. When the nail gun 4 moves forward to drive nails, the base body 3b moves backward against the elastic force of the spring 8 to strengthen the pressing of the hard cotton felt so that it is stably positioned, ensuring that the hard cotton felt does not deviate during the nail driving process, thereby further improving the working stability and accuracy.

[0039] In this embodiment,

[0040] The connection method between the straight piece 5 and the base body 3b is as follows: As Figure 2 shown, the base body 3b is horizontally penetrated with a strip-shaped groove 3d at the position of the vertical plane 3c. The straight piece 5 is located within the strip-shaped groove 3d, and the front end of the straight piece 5 extends out of the strip-shaped groove 3d. The rotating shaft 6 is located within the strip-shaped groove 3d. The straight piece 5 is fixedly connected to the rotating shaft 6, and both ends of the rotating shaft 6 are pivotally connected to the base body 3b. The strip-shaped groove 3d includes two groove walls arranged side by side up and down, and the distance between the two groove walls is greater than the thickness of the straight piece 5. The design of the strip-shaped groove 3d is used to shorten the swing stroke of the straight piece 5, making the overall reaction more efficient and improving the processing efficiency.

[0041] Furthermore, the front side of the base body 3b further includes an introduction plane 3e that is obliquely upward relative to the nail gun 4. The introduction plane 3e is below the vertical plane 3c, and the introduction plane 3e and the vertical plane 3c are in arc transition. With the above design, when the base 2 moves downward, the vertical plane 3c can smoothly move downward to contact the side wall of the mattress frame, and the working stability is better.

[0042] The sliding method of the base body 3b and the main body 3a is as follows: A linear guide rail 9 is horizontally fixed on the main body 3a, and the linear guide rail 9 is on the left side of the base body 3b. The linear guide rail 9 is higher than the straight piece 5, and the length of the linear guide rail 9 extends back and forth. A guide block 10 is installed on the linear guide rail 9, and the upper side of the base body 3b is fixedly connected to the guide block 10. The cooperation of the linear guide rail 9 and the guide block 10 realizes the sliding connection between the base body 3b and the main body 3a, which has the advantages of simple structure and stable operation.

[0043] The installation method of the spring 8 is as follows: A screw 11 is horizontally fixed on the main body 3a. The screw 11 and the linear guide rail are in the same length direction. The spring 8 is sleeved on the rod part of the screw 11, and both ends of the spring 8 act on the rear side of the base body 3b and the main body 3a respectively. The screw 11 is used for both the positioning of the spring 8 and the telescopic guiding of the spring 8. While simplifying the structure, it can improve the working stability.

[0044] The type of the sensor 7 is a proximity switch, and the proximity switch includes a straight rod-shaped body, and the body is vertically fixed on the main body 3a. Naturally, the type of the sensor 7 can also be a pressure sensor 7.

[0045] The driving mechanism is as follows: it includes a connecting seat 12, a first motor 13, and a front link 14, a driven link 15, a driving link 16, and a rear link 17 arranged in sequence from front to back.

[0046] Among them,

[0047] The above-mentioned sensor 7 is used to control the first motor 13 to turn off.

[0048] As Figure 3 and Figure 4 shown, both the upper and lower ends of the rear link 17 are respectively hinged to the connecting seat 12 and the base 2 through a horizontally arranged rear shaft 18; both the upper and lower ends of the driving link 16 are also respectively hinged to the connecting seat 12 and the base 2 through a horizontally arranged rear shaft 18; the upper ends of the front link 14 and the driven link 15 are respectively hinged to the connecting seat 12 through a horizontally arranged front shaft 19, and the lower ends of the front link 14 and the driven link 15 are both fixedly connected to the main body 3a. The axes of both the front shaft 19 and the rear shaft 18 extend left and right.

[0049] In the actual product, both ends of the front shaft 19 are pivotally connected to the connecting seat 12; both ends of the upper rear shaft 18 are pivotally connected to the connecting seat 12, and both ends of the lower rear shaft 18 are pivotally connected to the base 2.

[0050] Furthermore, the number of the front link 14, the driven link 15, the driving link 16, and the rear link 17 is two, and the two front links are arranged side by side left and right, the two driven links 15 are arranged side by side left and right, the two driving links 16 are arranged side by side left and right, and the two rear links 17 are arranged side by side left and right to improve the swinging stability of the main body 3a. The upper ends of the two rear links 17 are connected in series through the same rear shaft 18; the lower ends of the two rear links 17 are also connected in series through the same rear shaft 18. The cooperation of the driven link 15, the driving link 16, and the front link 14 with the shaft is the same as that of the rear link 17, and will not be introduced in detail here.

[0051] The first motor 13 is fixed on the base 2, and the first motor 13 drives the rear shaft 18 connected to the lower end of the driving link 16 to rotate through a gear transmission structure. Small gears one 20 are fixed on the rear shaft 18 connected to the upper end of the driving link 16 and the front shaft 19 connected to the driven link 15, and the two small gears one 20 are meshed with each other. Among them, the gear transmission structure includes a large gear 21 fixed on the rear shaft 18 connected to the lower end of the driving link 16 and a small gear two 22 fixed on the main shaft of the motor, and the small gear two 22 is meshed with the large gear 21.

[0052] The link assembly composed of the front link 14, the driven link 15, the driving link 16 and the rear link 17 not only effectively increases the stroke of the nail gun 4 to adapt to different sizes of mattresses, but also makes the overall structure more compact, so as to effectively shorten the horizontal length when the equipment is not working and reduce the space occupation.

[0053] The lifting mechanism includes a second motor 23 fixed on the bracket 1, and the second motor 23 is connected to the base 2 through a lead screw-nut transmission mechanism. The lead screw-nut transmission mechanism is a conventional structure and will not be described in detail here. At this time, the sensor 7 is used to control the start of the second motor 23. Further, the base 2 is slidably connected to the bracket 1 up and down to improve the sliding accuracy and stability of the base 2 and effectively ensure the accuracy of the nail height correction of the nail gun 4. Among them, the specific sliding mode of the base 2 and the bracket 1 is as follows: A second linear guide rail 24 is vertically fixed on the bracket 1, a second guide block is installed on the second linear guide rail 24, and the rear side of the base 2 is fixedly connected to the second guide block.

A magazine for stacking the bullets of the nail gun 4 up and down is formed on the material plate 25, and a strip-shaped arrangement channel is provided through the bottom of the magazine. In actual use, the bullets in the magazine fall into the arrangement channel in sequence. The feeding channel 4a and the discharging channel have the same length extension direction, and the front end of the discharging channel is connected to the rear end of the feeding channel 4a. A push plate is arranged in the rear end of the discharging channel, and the push plate is pushed by a driving member to push the bullets in the discharging channel into the feeding channel 4a to realize automatic loading of the nail gun 4. Among them, the driving member can be a cylinder, an electric push rod or other components. Embodiment 2
