Description

Technical Field

[0001] The utility model relates to the technical field of polyvinyl fluoride product processing, and particularly relates to a cutting device for polyvinyl fluoride products. Background Art

[0002] Polyvinyl fluoride can be processed into various materials such as rods, tubes, plates, films, tapes, ropes, packing rings, gaskets, etc. When polyvinyl fluoride products are processed into gaskets, polyvinyl fluoride is usually first processed into tubular products, and then the end face of the polyvinyl fluoride tubular product is cut by a blade to cut the end face into sheet-shaped gaskets. In actual production, we found that when cutting polyvinyl fluoride gaskets, sometimes the gasket thickness needs to be adjusted. At this time, professional engineers need to re-edit the blade movement cutting program and input it into the machine tool, and then re-use the raw material of the polyvinyl fluoride tubular product for tool setting. In the process from re-editing the program to inputting the new program into the machine tool, due to the complex operation, ordinary operators cannot participate and can only wait for professional engineers, wasting time invisibly; moreover, when the machine tool uses polyvinyl fluoride tubular products to cut gaskets, after the polyvinyl fluoride tubular product is cut short, the blade moves towards the polyvinyl fluoride tubular product, and at this time, the cut gaskets will scatter towards the clamping disc direction of the polyvinyl fluoride tubular product, which is not easy to collect. Content of the Utility Model

[0003] Therefore, in order to solve the above deficiencies, the utility model provides a cutting device for polyvinyl fluoride products herein. When adjusting the cutting thickness of the gasket, professional engineers do not need to re-edit the program to participate, and ordinary operators can directly adjust the blade thickness, thereby adjusting the cutting thickness of the gasket, saving time; moreover, when the polyvinyl fluoride tubular product is cut short, the blade does not need to move towards the polyvinyl fluoride tubular product, but the polyvinyl fluoride tubular product moves towards the blade, so that the cut gaskets will not scatter in a certain direction and are convenient to collect.

[0004] The present utility model is implemented as follows. A cutting device for polyvinyl fluoride products is constructed, including: a main body bed frame, a braking side plate is installed at one end of the main body bed frame, a supporting side plate is installed at the other end of the main body bed frame, an installation hole is opened at the middle position near the top of the braking side plate, and a braking motor A is installed inside the installation hole; a moving fastening frame is installed at the top position between the braking side plate and the supporting side plate, a sliding through groove is opened at the middle position of the supporting side plate, a laser distance sensor is slidably connected inside the sliding through groove, and an outer protective shell is wrapped outside the laser distance sensor; a cutting frame is installed at the top of the main body bed frame near the supporting side plate, and the cutting frame is composed of a second electric slide rail, a right-angle plate, a sleeve blade, a size scale bar, a large-head threaded rod, and a support box.

[0005] As a supplement to the above, it should be noted that: the laser distance sensor is fixed on the outside of the slide plate of the first electric slide rail by relying on the outer protective shell, the laser distance sensor can slide up and down through the sliding through groove, the cutting frame, the braking side plate, the moving fastening frame, the second electric slide rail, and the first electric slide rail are controlled to operate through the control cabinet, the size scale bar can be used as a reference for the size distance to adjust the position of the sleeve blade, one end of the large-head threaded rod is provided with a thin screw rod, which is adapted to the small threaded through hole, and the position of the sleeve blade is fixed by screwing the large-head threaded rod through the small threaded through hole and contacting the right-angle plate. The material sliding channel is located on one side of the end face of the support box; the staff clamps a polyvinyl fluoride round tube product with appropriate size specifications through the moving fastening frame, then sends it to the sleeve blade by relying on the moving fastening frame, and then drives the sleeve blade to reciprocate through the second electric slide rail to cut out a thin gasket on the end face of the polyvinyl fluoride round tube product. The cut thin gasket falls down and enters the material sliding channel, and then slides away through the material sliding channel.

[0006] Furthermore, the sleeve blade is composed of a through-hole sleeve, a cutting blade, and a small threaded through hole. The cutting blade is arranged on the side of the end face of one end of the through-hole sleeve, and the small threaded through hole is opened on one side of the through-hole sleeve;

The other end of the limiting rod is fixedly connected to the braking side plate. The other end of the lead screw passes through the surface of the braking side plate through a bearing and enters the mounting hole. The part entering the mounting hole is fixedly connected to the output shaft of the braking motor A. The braking motor A is a servo motor. After the braking motor A operates, it drives the lead screw to rotate. The rotation of the lead screw relies on the large threaded through hole to push the sliding carriage to drive the fastening block to move.

[0010] Further, a large threaded through hole is penetrated and opened in the middle of the sliding carriage, and limiting through holes are opened at both ends of the large threaded through hole;

[0011] The lead screw passes through the large threaded through hole and is adapted to the large threaded through hole. The limiting rod passes through the limiting through hole, and the sliding carriage slides on the outside of the limiting rod relying on the limiting through hole.

[0013] The braking motor B is a servo motor. The output shaft of the braking motor B is fixedly connected to the back of the three-jaw chuck. The jaw area of the three-jaw chuck is located outside the inner groove, facilitating the sliding of the jaws of the three-jaw chuck. When the braking motor B operates, it drives the three-jaw chuck to rotate, and the polyvinyl fluoride round tube product is clamped by the three-jaw chuck.

The relay and the single-chip microcomputer are electrically connected by an adapted circuit. There are four groups of relays. The four groups of relays are respectively connected to the braking motor B, the braking motor A, the first electric slide rail, and the second electric slide rail by an adapted circuit, so that the four groups of relays are respectively used as automatic power switches for the braking motor B, the braking motor A, the first electric slide rail, and the second electric slide rail. The single-chip microcomputer is respectively connected to the motors in the braking motor B, the braking motor A, the first electric slide rail, and the second electric slide rail through an H-bridge circuit, facilitating the control of the rotation directions of the motors in the braking motor B, the braking motor A, the first electric slide rail, and the second electric slide rail.

At the same time, the distance information measured by the laser ranging sensor between the end face of the polyvinyl fluoride round tube product and the laser ranging sensor itself is transmitted to the single-chip microcomputer.

[0016] The beneficial effects of the present utility model can be specifically reflected after analysis as follows:

[0017] Advantage 1: When adjusting the cutting thickness of the shim, the operator only needs to unscrew the large-head threaded rod, slide the sleeve blade towards the brake side plate, so that the cutting blade slides towards the brake side plate according to the size scale bar by a distance equal to the thickness of the shim to be cut plus the thickness of the cutting blade. Then, screw the large-head threaded rod into the small threaded through-hole by relying on its thin screw rod to contact the right-angle plate to fix the position of the sleeve blade, thereby adjusting the cutting thickness of the shim. There is no need for professional engineers to re-edit the blade or participate in the movement program of the polyvinyl fluoride tubular product, saving time.

[0018] Advantage 2: When the polyvinyl fluoride tubular product is cut short, the single-chip microcomputer automatically relies on the corresponding relay to turn on the brake motor A to operate. At this time, the moving fastening frame carries the polyvinyl fluoride round tube product and moves towards the support side plate to approach the sleeve blade, so that the end face of the polyvinyl fluoride tubular product is always cut at the same position, and the cut shims fall concentratedly inside the sliding material channel for easy collection.

[0033] Embodiment: A polyvinyl fluoride product cutting device provided in the present application, in combination with Figure 1-4 and Figure 10, a mounting hole 21 is provided in the middle position near the top of the braking side plate 2, and a braking motor A22 is installed inside the mounting hole 21; the moving fastening frame 3 is composed of a sliding frame 31, a limiting rod 32, a lead screw 33 and a fastening block 34. The limiting rod 32 penetrates through both ends of the sliding frame 31, the lead screw 33 penetrates through the middle of the sliding frame 31, and the fastening block 34 is connected to the bottom of the sliding frame 31; the fastening block 34 is composed of a block body 341, an inner groove 342, a braking motor B343 and a three-jaw chuck 344. The inner groove 342 is opened on one side of the block body 341, the braking motor B343 is installed at the inner end of the inner groove 342, and the three-jaw chuck 344 is installed at the opening end of the inner groove 342 through a bearing; a hollow cavity 71 is provided in the middle position of the control cabinet 7, a single-chip microcomputer 72 and a relay 73 are installed inside the hollow cavity 71, and a human-machine interaction interface board 74 is installed on the top of the control cabinet 7.

[0034] As an example, it should be noted that: the staff tightly fixes a polyvinyl fluoride round tube product with appropriate specifications and dimensions through the three-jaw chuck 344, and then the staff operates the human-machine interaction interface board 74 to turn on the power supply of the braking motor A22 by relying on the single-chip microcomputer 72 and the corresponding relay 73. Then the braking motor A22 runs. At this time, the braking motor A22 will drive the lead screw 33 to rotate and push the sliding frame 31 to drive the fastening block 34 and the polyvinyl fluoride round tube product to move towards the support side plate 4 until the polyvinyl fluoride round tube product contacts the cutting blade 632 side of the sleeve blade 63. Then the power supply of the braking motor A22 is disconnected. It should be noted that at this time, the sleeve blade 63 is at the end of the second electric slide rail 61 farthest from the control cabinet 7.

[0035] Combined with Figure 5-9 , a sliding through groove 41 is provided in the middle position of the support side plate 4, a laser distance sensor 43 is slidably connected inside the sliding through groove 41, and an outer protective shell 42 is wrapped outside the laser distance sensor 43; the cutting frame 6 is composed of a second electric slide rail 61, a right-angle plate 62, a sleeve blade 63, a size scale bar 64, a large-headed threaded rod 65 and a support box 66. The second electric slide rail 61 is installed on the top of the support box 66, the right-angle plate 62 is installed at one end of the slide plate of the second electric slide rail 61, the sleeve blade 63 is nested outside the right-angle plate 62, the size scale bar 64 is engraved on one side of the right-angle plate 62, and the large-headed threaded rod 65 is screwed into one side of the sleeve blade 63; the sleeve blade 63 is composed of a through-hole sleeve 631, a cutting blade 632 and a small threaded through-hole 633. The cutting blade 632 is provided on the side of the end face of one end of the through-hole sleeve 631, and the small threaded through-hole 633 is opened on one side of the through-hole sleeve 631.

[0036] As an example, it should be noted that after the cutting blade 632 side of the polyvinyl fluoride round tube product contact sleeve blade 63 is contacted, the staff operates the human-computer interaction interface board 74 to rely on the single-chip microcomputer 72 to cooperate with the corresponding relay 73 to turn on the power supply of the motor in the second electric slide rail 61. At this time, the second electric slide rail 61 runs, causing its slide plate to drive the right-angle plate 62, the sleeve blade 63, etc. to move to the end close to the control cabinet 7. Then, the power supply of the laser distance sensor 43 is turned on. Then, the staff operates the human-computer interaction interface board 74 again to rely on the single-chip microcomputer 72 to cooperate with the corresponding relay 73 to turn on the power supply of the motor in the first electric slide rail 5, and controls the first electric slide rail 5 to run to drive the outer housing 42 and the laser distance sensor 43 to move up and down until the laser distance sensor 43 detects the distance between the end face of the polyvinyl fluoride round tube product and the laser distance sensor 43 itself. Then, the staff operates the human-computer interaction interface board 74 to rely on the single-chip microcomputer 72 to cooperate with the corresponding relay 73 to turn off the power supply of the motor in the first electric slide rail 5. Then, the laser distance sensor 43 transmits the distance information between the end face of the polyvinyl fluoride round tube product and the laser distance sensor 43 itself to the single-chip microcomputer 72 for storage. Then, according to the thickness of the polyvinyl fluoride product gasket to be cut, the staff unscrews the large-head threaded rod 65 and slides the sleeve blade 63 towards the brake side plate 2, so that the cutting blade 632 slides towards the brake side plate 2 according to the dimension scale bar 64 by a distance equal to the thickness of the gasket to be cut plus the thickness of the cutting blade 632. Then, the large-head threaded rod 65 is screwed into the small threaded through hole 633 by its thin screw rod to contact the right-angle plate 62 to fix the position of the sleeve blade 63.

[0037] After the position of the sleeve blade 63 is adjusted, the operator then operates the human-machine interface panel 74 to turn on the power supply of the braking motor B343 by relying on the single-chip microcomputer 72 in cooperation with the corresponding relay 73. The braking motor B343 runs to drive the three-jaw chuck 344 to rotate, and the three-jaw chuck 344 rotates to drive the polyvinyl fluoride round tube product to rotate. Then the operator operates the human-machine interface panel 74 again to turn on the power supply of the motor in the second electric slide rail 61 by relying on the single-chip microcomputer 72 in cooperation with the corresponding relay 73. Then, through the single-chip microcomputer 72, the output shaft of the motor in the second electric slide rail 61 is adjusted to rotate in the reverse direction by relying on the corresponding H-bridge circuit, so that the slide plate of the second electric slide rail 61 drives the right-angle plate 62 and the sleeve blade 63 to move away from the control cabinet 7 to cut the rotating polyvinyl fluoride round tube product, and cut its end face into gaskets. After the gaskets are cut out, they fall inside the material sliding channel 11. At this time, the operator operates the human-machine interface panel 74 again to control the output positive shaft of the motor in the second electric slide rail 61 to rotate by relying on the single-chip microcomputer 72 through the corresponding H-bridge circuit, so that the right-angle plate 62 and the sleeve blade 63 return to the direction of the control cabinet 7. At this time, the laser distance sensor 43 detects that the distance between itself and the end face of the polyvinyl fluoride round tube product has changed. Then the laser distance sensor 43 feeds back the distance information to the single-chip microcomputer 72 for comparison with the previously stored distance information. The single-chip microcomputer 72 automatically turns on the braking motor A22 to run by relying on the corresponding relay 73. At this time, the moving fastening frame 3 carries the polyvinyl fluoride round tube product and moves towards the support side plate 4 until the laser distance sensor 43 detects that the distance between itself and the end face of the polyvinyl fluoride round tube product is the stored data size distance. At this time, the laser distance sensor 43 transmits the information back to the single-chip microcomputer 72 for comparison. After the single-chip microcomputer 72 compares and confirms, it then disconnects the power supply of the braking motor A22 by relying on the corresponding relay 73. At this time, the process of cutting gaskets from one polyvinyl fluoride round tube product is completed. Then the operator operates the human-machine interface panel 74 to record the above process through the single-chip microcomputer 72, and then operates the human-machine interface panel 74 to control the single-chip microcomputer 72 to automatically cycle the above process to cut the polyvinyl fluoride round tube product.

[0038] In summary, for the polyvinyl fluoride product cutting device of the present utility model, when adjusting the cutting thickness of the gasket, there is no need for professional engineers to re-edit the program to participate. Ordinary operators can directly adjust the blade thickness, thereby adjusting the cutting thickness of the gasket, saving time; moreover, when the polyvinyl fluoride tubular product is cut short, the blade does not need to move towards the polyvinyl fluoride tubular product. Instead, the polyvinyl fluoride tubular product moves towards the blade, so that the cut gaskets will not scatter in a certain direction, which is convenient for collection.

[0039] The above are only the embodiments of the present utility model. Common knowledge such as the specific structures and characteristics known in the solutions is not described in detail herein. It should be noted that for those skilled in the art, without departing from the structure of the present utility model, several modifications and improvements can be made, which should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicability of the patent. The protection scope required by this application shall be subject to the content of its claims, and the specific implementation manners and the like recorded in the specification can be used to interpret the content of the claims.
