Description

Technical Field

[0001] This invention relates to the technical field of continuous foaming production lines, and more specifically to a production line follow-up cutting device. Background Technology

[0002] In existing technologies, the factors affecting foaming production efficiency fall into two main categories: chemical variables, also known as process formulations, and physical variables, which mainly include the following:

[0003] 1. Types of foaming machinery;

[0004] 2. Metering: Number and composition of metering components, temperature control, and metering system control;

[0005] 3. Mixing head: structural design, mixing speed;

[0006] 4. Transport machinery: operating status and speed;

[0007] 5. Reliability of the paper receiving and discharging system and paper quality;

[0008] 6. Ambient temperature, atmospheric pressure, and air humidity.

[0009] The key physical variable is the level of each component of the foaming production line. Among them, the uninterrupted operation of the transport machinery is an effective means to improve the foaming production line. The cutting equipment used in the cutting process of the existing production line has poor versatility and cannot guarantee the synchronization of cutting while the material is being transported forward. It is necessary to stop the material during the cutting process and then transport it again after cutting, which reduces the overall production efficiency of the foaming production line. Therefore, we provide a production line follow-up cutting device to solve the above problems. Summary of the Invention

[0010] In order to avoid and overcome the technical problems existing in the prior art, the present invention provides a production line follow-up cutting device, which realizes one-time cutting in the state of material conveying.

[0011] To achieve the above objectives, the present invention employs a production line follow-up cutting device, comprising:

[0012] The cutting device body is equipped with a cutting platform. The workpiece to be cut is conveyed to the cutting platform and continuously output forward under the drive of the first drive unit. The cutting device body is equipped with a second drive unit to drive the cutting platform to move synchronously with the profile.

[0013] The aforementioned cutting platform is equipped with a clamping part that moves vertically to clamp the workpiece to be cut from top to bottom; the cutting platform is also equipped with a cutting part, which includes a saw blade, a third driving part is a power source for driving the saw blade, and a fourth driving part drives the cutting platform to move in a direction perpendicular to the direction of travel of the workpiece to be cut; wherein:

[0014] One reciprocating motion of the above-mentioned cutting platform completes the cutting and transfer of one workpiece to be cut.

[0015] When the above structure is performing a cutting operation, the workpiece to be cut is conveyed to the cutting platform and pressed and fixed under the action of the clamping part. Then, the cutting platform and the cutting material are moved synchronously through the first drive part and the second drive part. In the process of one reciprocating motion of the cutting platform, a complete cutting process is completed, realizing one-time cutting under the state of cutting material conveying, improving the work efficiency in the cutting process, and thus improving the overall production efficiency of the foaming production line.

[0016] As a further optimization of the above solution, the first drive unit includes a scissor telescopic structure arranged on the side of the cutting platform and extending and retracting along the direction of travel of the workpiece to be cut. The scissor telescopic structure includes an upper part as a drive module and a lower part as an inertial module. The drive module includes a roller with a rotation function. The drive end of the roller is provided with two first connecting wheels. A first belt structure connects the two first connecting wheels on the same plane on two adjacent rollers. The first motor is designed as the power source of the first drive unit and is provided with a second connecting wheel at the drive end and is connected to the first connecting wheels on the same plane on adjacent rollers through a second belt structure. The second drive unit includes a second motor arranged on the cutting platform. A first drive gear is mounted on the output shaft of the second motor. A first fixed rack is arranged along the length direction of the cutting device body. The first drive gear and the first fixed rack are a mating structure, and the first drive gear moves linearly along the first fixed rack under the drive of the second motor.

[0017] The above structure realizes the transportation of the workpiece to be cut through the scissor telescopic structure. During the process of the cutting platform moving linearly driven by the second drive unit, the scissor telescopic structure extends and retracts synchronously to transport the workpiece, thus helping to realize the synchronous movement of the cutting platform and the cutting material.

[0018] As a further optimization of the above solution, the fourth drive unit includes a third motor, a second drive gear is mounted on the output shaft of the third motor, and a second fixed rack is arranged along the width direction of the cutting device body. The second drive gear and the second fixed rack are in a mating structure, and the second drive gear moves linearly along the second fixed rack under the drive of the third motor.

[0019] The structural design of the second and fourth drive units enables the cutting platform to move in two directions, ensuring that during actual operation, the cutting platform can both transport the workpiece to be cut and perform the cutting action.

[0020] As a further optimization of the above solution, the cutting section includes a cutting saw frame mounted on the cutting platform. The cutting saw frame has an arc-shaped receiving space for the saw blade to enter. The side of the cutting saw frame away from the workpiece to be cut is the driving side, and the other side is the cutting side. The driving wheel is arranged on the driving side, and two driven wheels are arranged on the cutting side. The saw blade passes through the driving wheel and the two driven wheels to form a closed cutting saw structure. The band saw motor is the power source for the driving wheel and drives the driving wheel to rotate so that the saw blade moves around the shape of the cutting saw structure. As a further optimization of the above solution, the two driven wheels are located on the same vertical plane and the driving wheel and the two driven wheels form a triangular shape.

[0021] The above-described structure design enables a fully enclosed cutting saw structure, ensuring the cutting effect of the cutting saw on the workpiece. In addition, for the cutting saw, this invention adopts an arc-shaped combination structure and uses a three-point triangular arrangement for fixation, which provides greater stability compared to two-point fixation.

[0022] As a further optimization of the above solution, the upper part of the accommodating space is provided with an upper rotating seat for the band saw, and the lower part is provided with a lower rotating seat for the band saw. Both the upper and lower rotating seats for the band saw are provided with limiting modules to restrict the position of the saw blade; wherein:

[0023] As a further optimization of the above solution, the limiting module includes a first gear and a second gear that mesh with each other. The driving component drives the first gear to rotate. The second gear has a hollow structure and an opening that is arranged in the limiting path of the saw blade. The saw blade enters the hollow part of the second gear along the opening and the limiting path of the saw blade is closed by the rotation of the second gear, so as to limit the position of the saw blade and avoid the saw blade from changing position significantly during the cutting process, which would affect the cutting effect.

[0024] As a further optimization of the above solution, a lifting device is also included. The lifting device includes a screw nut installed on the cutting saw frame, a screw rod mounted on the screw nut, and a drive unit that is the power source for the screw rod and drives the screw rod to rotate. The screw rod is provided with a bearing seat that moves linearly along the screw rod as it rotates. The bearing seat and the rotating seat on the band saw are an integral structure. Through the action of the drive unit, the screw nut is rotated, which in turn drives the screw rod to rotate, thereby realizing the positional change of the bearing seat and the rotating seat on the band saw in the vertical direction.

[0025] As a further optimization of the above solution, the pressing part includes a pressing frame installed on the lower rotating seat. The pressing frame is provided with at least one pressing cylinder. The extrusion component is installed at the output end of the pressing cylinder and moves up and down under the action of the pressing cylinder. The extrusion component is a lifting roller.

[0026] The aforementioned clamping structure abandons the traditional flat-press structure and is replaced by a rolling structure, which reduces the contact area with the workpiece to be cut during the clamping process and reduces damage to the workpiece to be cut during the clamping process.

[0027] The production line follow-up cutting device of the present invention has the following beneficial effects:

[0028] 1. A production line follow-up cutting device of the present invention, when performing a cutting operation, the workpiece to be cut is conveyed to the cutting platform and pressed and fixed under the action of the clamping part. Then, the cutting platform and the cutting material are moved synchronously through the first driving part and the second driving part, and a complete cutting process is completed in one reciprocating motion of the cutting platform. This realizes one-time cutting under the condition of cutting material conveying, improves the working efficiency of the cutting process, and thus improves the overall production efficiency of the foaming production line.

[0029] 2. A production line follow-up cutting device of the present invention realizes the transportation action of the workpiece to be cut through the scissor telescopic structure, and during the process of the cutting platform being driven to move linearly by the second drive unit, the scissor telescopic structure extends and retracts synchronously and transports the workpiece to be cut, thereby assisting in realizing the synchronous movement of the cutting platform and the cutting material.

[0030] 3. The production line follow-up cutting device of the present invention adopts a cutting saw structure in a fully enclosed state to ensure the cutting effect of the cutting saw structure on the workpiece to be cut. At the same time, for the above-mentioned cutting saw, the present invention adopts an arc-shaped combination structure and a three-point structure similar to a triangle arrangement for fixation, which is more stable than two-point fixation.

[0031] 4. The production line follow-up cutting device of the present invention uses a limiting module to restrict the position of the saw blade, so as to avoid the saw blade from changing position significantly during the cutting process, which would affect the cutting effect.

[0032] 5. The production line follow-up cutting device of the present invention abandons the traditional flat pressing structure in the pressing structure and replaces it with a rolling pressing structure, thereby reducing the contact area between the device and the workpiece to be cut during the pressing process and reducing the damage to the workpiece to be cut during the pressing process.

The driving wheel 64 is arranged on the driving side, and two driven wheels 65 are arranged on the cutting side. The saw blade 61 passes through the driving wheel 64 and the two driven wheels 65 to form a closed cutting saw structure. The band saw motor is the power source for the driving wheel 64 and drives the driving wheel 64 to rotate so that the saw blade 61 moves around the shape of the cutting saw structure. As a further optimization of the above scheme, the two driven wheels 65 are located on the same vertical plane and the driving wheel 64 and the two driven wheels 65 form a triangular shape.

[0052] like Figure 1 As shown, the third drive unit 7 is a band saw motor, the output shaft of which is connected to the drive wheel 64 and drives the drive wheel 64 to rotate.

[0053] Please refer to Figure 2 as well as Figure 3 The first drive unit 3 includes a scissor telescopic structure arranged on the side of the cutting platform 2 and extending and retracting along the direction of travel of the workpiece to be cut. The scissor telescopic structure includes an upper part as a drive module 31 and a lower part as an inertial module 32. The drive module 31 includes a roller 311 with a rotation function. The drive end of the roller 311 is provided with two first connecting wheels 312. A first belt structure 313 connects the two first connecting wheels 312 on the same plane on two adjacent rollers 311. The first motor 314 is designed as the power source of the first drive unit 3 and is provided with a second connecting wheel 315 at the drive end and is connected to the first connecting wheels 312 on the same plane on adjacent rollers 311 through a second belt structure 316.

[0054] like Figure 4As shown, the second drive unit 4 includes a second motor 41 mounted on the cutting platform 2, a first drive gear 42 mounted on the output shaft of the second motor 41, and a first fixed rack 43 arranged along the length direction of the cutting device body 1. The first drive gear 42 and the first fixed rack 43 are in a mating structure, and the first drive gear 42 moves linearly along the first fixed rack 43 under the drive of the second motor 41.

[0055] like Figure 5 As shown, the pressing part 5 includes a pressing frame 51 mounted on the lower rotating seat. The pressing frame 51 is provided with at least one pressing cylinder 52. The extrusion member 53 is mounted on the output end of the pressing cylinder 52 and moves up and down under the action of the pressing cylinder 52. The extrusion member 53 is a lifting roller 311.

[0056] It should be noted that in this embodiment, there are two pressing cylinders 52, which are placed on both sides and connected by a synchronizer to achieve synchronous operation of the two pressing cylinders 52.

[0057] like Figure 7 As shown, the fourth drive unit 8 includes a third motor 81, a second drive gear 82 mounted on the output shaft of the third motor 81, and a second fixed rack 83 arranged along the width direction of the cutting device body 1. The second drive gear 82 and the second fixed rack 83 are in a mating structure, and the second drive gear 82 moves linearly along the second fixed rack 83 under the drive of the third motor 81.

[0058] It should be noted that both the second drive unit 4 and the fourth drive unit 8 are provided with a guide structure, which includes a guide rail. The cutting platform is slidably fitted onto the guide rail to ensure that the cutting platform moves in a straight line.

[0059] like Figures 1-7 As shown in the figure, the working process of the production line follow-up cutting device provided in this embodiment is as follows:

[0060] The workpiece to be cut is conveyed to the cutting platform 2. The pressing cylinder 52 drives the extruder 53 to press down and clamp the workpiece to be cut. Then, the first motor 314, the second motor 41 and the third motor 81 move synchronously. The first motor 314 drives the second connecting wheel 315 to rotate. Under the action of the second belt structure 316, the first connecting wheel 312 is driven to rotate. Under the action of the first belt structure 313, all the first connecting wheels 312 rotate and drive the roller 311 to rotate. The second motor 41 drives the first driving gear 42 to rotate and move along the first fixed rack 43. The third motor 81 drives the second driving gear 82 to rotate and move along the second fixed rack 83 until the workpiece to be cut is completed. At this time, the second moving part drives the cutting platform 2 to the end of the length direction of the cutting device body 1. The clamping part 5 releases the workpiece to be cut. Under the action of the roller 311, the cut material is transported to the next process. At this time, the cutting platform 2 and the cutting part 6 are reset under the action of the first driving part 3 and the second driving part 4.

[0061] Please refer to the instruction manual appendix. Figure 1-9 The present invention provides a technical solution: a second embodiment of a production line follow-up cutting device, comprising:

[0062] The cutting device body 1 is provided with a cutting platform 2. The workpiece to be cut is conveyed to the cutting platform 2 and continuously output forward under the drive of the first drive unit 3. The cutting device body 1 is provided with a second drive unit 4 to drive the cutting platform 2 to move synchronously with the profile.

[0063] The cutting platform 2 is provided with a pressing part 5 that moves in the vertical direction to press the workpiece to be cut from top to bottom; the cutting platform 2 is also provided with a cutting part 6, which includes a saw blade 61, a third driving part 7 is a power source for driving the saw blade 61, and a fourth driving part 8 drives the cutting platform 2 to move in the vertical direction of the direction of travel of the workpiece to be cut.

[0064] in:

[0065] One reciprocating motion of the cutting platform 2 completes the cutting and transfer of one workpiece to be cut.

[0066] like Figure 6As shown, the cutting section 6 includes a cutting saw frame 62 mounted on the cutting platform 2. The cutting saw frame 62 has an arc-shaped receiving space 63 for the saw blade 61 to enter. The side of the cutting saw frame 62 away from the workpiece to be cut is the driving side, and the other side is the cutting side. The driving wheel 64 is arranged on the driving side, and two driven wheels 65 are arranged on the cutting side. The saw blade 61 passes through the driving wheel 64 and the two driven wheels 65 to form a closed cutting saw structure. The band saw motor is the power source for the driving wheel 64 and drives the driving wheel 64 to rotate so that the saw blade 61 moves around the shape of the cutting saw structure. As a further optimization of the above scheme, the two driven wheels 65 are located on the same vertical plane and the driving wheel 64 and the two driven wheels 65 form a triangular shape.

[0067] As a further optimization of the above scheme, such as Figure 6 , Figure 8 as well as Figure 9 As shown, the upper part of the accommodating space 63 is provided with an upper rotating seat 631 for the band saw, and the lower part is provided with a lower rotating seat 632 for the band saw. Both the upper rotating seat 631 and the lower rotating seat 632 are provided with limiting modules 9 to restrict the position of the saw blade 61; wherein:

[0068] As a further optimization of the above solution, the limiting module 9 includes a first gear 91 and a second gear 92 that mesh with each other. The driving component 93 drives the first gear 91 to rotate. The second gear 92 has a hollow structure and an opening 921. The opening 921 is arranged in the limiting path 922 of the saw blade 61. The saw blade 61 enters the hollow part of the second gear 92 along the opening 921 and the limiting path 922 of the saw blade 61 is closed under the action of the rotation of the second gear 92, so as to limit the use position of the saw blade 61 and avoid the saw blade 61 from undergoing a large position change during the cutting process, which would affect the cutting effect.

[0069] like Figure 8 as well as Figure 9 As shown, the working steps of the limiting module 9 in this embodiment are as follows:

[0070] First, during the adjustment process, the saw blade 61 is fed into the hollow part of the second gear 92 along the opening 921. Then, the drive component 93 drives the first gear 91 to rotate, which in turn drives the second gear 92 to rotate, and makes the opening 921 offset from the limiting path 922. At this time, the limiting work of the saw blade 61 is realized.

[0071] As a further optimization of the above solution, the lifting device 66 includes a screw nut 661 mounted on the cutting saw frame 62, a screw rod 662 mounted on the screw nut 661, a drive unit 663 serving as the power source for the screw rod 662 and driving the screw rod 662 to rotate, and a bearing seat 664 mounted on the screw rod 662 that moves linearly along the screw rod 662 as it rotates, and the bearing seat 664 and the rotating seat 631 on the band saw are an integral structure.

[0072] It should be noted that the aforementioned driving component 663 is a handwheel connected to the lead screw 661. By rotating the handwheel, the lead screw 661 is rotated, which in turn drives the lead screw 662 to rotate.

[0073] The working steps of the lifting device 66 in this embodiment are as follows:

[0074] First, during the height adjustment process, rotate the handwheel to drive the screw nut 661 to rotate, which in turn drives the lead screw 662 to rotate, causing the bearing seat 664 and the rotating seat 631 on the band saw to move up and down, thus completing the height adjustment of the rotating seat 631 on the band saw.

[0075] It should be noted that since the first gear 91 rotates slightly, in this embodiment, the driving component 93 is selected to drive the first gear 91 to rotate slightly during operation using a swing cylinder.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
