Description

A PVC board feeding device with a positioning structure Technical Field

[0001] This utility model relates to the field of PVC board technology, and in particular to a PVC board feeding device with a positioning structure. Background Technology

[0002] PVC sheets are a common type of plastic sheet, mainly made of polyvinyl chloride resin. PVC sheet feeding devices are used to automatically transport PVC sheets from storage locations or cutting areas to the next processing step, which can improve production efficiency, reduce manual operation, and ensure that the sheets maintain a stable feeding speed and accurate position throughout the processing.

[0003] Existing PVC board feeding devices typically use baffles of fixed height to support and transport the boards. They cannot adjust the support height of the baffles according to the actual amount of PVC boards being transported, thus limiting their ability to meet the needs of transporting large quantities of PVC boards.

[0004] Therefore, in view of the problem that the above-mentioned PVC board feeding device is limited in meeting the needs of conveying large quantities of PVC boards, this utility model adopts the design of setting a detachable extension plate at the upper end of the baffle through the mechanism component. When the extension plate is installed, the overall height of the baffle is raised, which is suitable for the conveying needs of large quantities of PVC boards. When the extension plate is removed, the height of the baffle remains unchanged, which is suitable for the conveying needs of regular batches of PVC boards. Summary of the Invention

[0005] To overcome the limitations of common PVC board feeding devices in handling large-volume PVC board conveying needs.

[0006] The technical solution of this utility model is: a PVC board feeding device with a positioning structure, including a positioning support, a drive roller, a driven roller and a transmission belt. The positioning support is configured as a "U" shaped structure. The drive roller is rotatably installed inside the positioning support, and the driven rollers are rotatably installed in an equally spaced arrangement inside the positioning support. A transmission belt is connected between the drive roller and the driven roller.

[0007] A drive control mechanism is provided on the side of the drive roller, a positioning adjustment mechanism is provided on the outer side of the transmission belt, and a support adjustment mechanism is provided below the positioning support seat.

[0008] Preferably, the drive control mechanism includes a positioning support frame, a driven gear, a drive gear, and a drive motor. An "n"-shaped positioning support frame is fixedly installed on the outer side wall of the positioning support seat. The support roller inside the drive roller passes through the positioning support seat and is rotatably installed on the inner side wall of the positioning support frame. The driven gear is fixedly installed on the outside of the support roller. The drive gear is meshed with the side of the driven gear. The drive motor is fixedly installed on the outer side wall of the positioning support frame. The output end of the drive motor passes through the positioning support frame and is connected to the outer side wall of the drive gear.

[0009] Preferably, both the driven gear and the driving gear are rotatably mounted to the outer side wall of the positioning support, and the diameter of the driven gear is larger than the diameter of the driving gear.

[0010] Preferably, the positioning adjustment mechanism includes a positioning baffle, an extension plate, a positioning T-shaped strip, and a positioning T-shaped groove. The positioning baffle is circumferentially fixedly installed on the outer wall of the transmission belt. The extension plate is fitted to the upper end of the positioning baffle. The positioning T-shaped strip is fixedly installed on the lower outer wall of the extension plate. The positioning T-shaped groove for the positioning T-shaped strip to be inserted is correspondingly opened on the upper outer wall of the positioning baffle.

[0011] Preferably, the outer side wall of the positioning baffle is symmetrically provided with a first threaded groove, and the first threaded groove communicates with the internal space of the positioning T-shaped groove. The outer side wall of the positioning T-shaped strip is provided with two sets of second threaded grooves that are aligned and communicate with each other. Fastening bolts are installed inside the first threaded groove and the second threaded groove, and the fastening bolts are embedded in the inside of the positioning baffle.

[0012] Preferably, the support adjustment mechanism includes piston columns, a support box, a support base, and a crossbar. Two sets of piston columns are symmetrically arranged on the bottom outer wall of the positioning support seat. The bottom ends of the piston columns are slidably installed inside the support box. The support base is fixedly installed on the bottom outer wall of the support box. A crossbar is connected between the two sets of support bases on the same side.

[0013] Preferably, the outer side wall of the support box is provided with a positioning threaded groove at equal intervals, and the outer side wall of the piston rod near the bottom end is provided with a mating threaded groove. Positioning bolts are installed inside the positioning threaded groove and the mating threaded groove. The rotating end of the positioning bolt is located on the outside of the support box, and an anti-slip strip is fixedly installed circumferentially on the outer side wall of the positioning bolt at the rotating end position.

[0014] The beneficial effects of this utility model are:

[0015] 1. This PVC board feeding device with a positioning structure features a detachable extension plate at the upper end of the baffle. When the extension plate is installed, the overall height of the baffle is raised, suitable for conveying large quantities of PVC boards. When the extension plate is removed, the height of the baffle remains unchanged, suitable for conveying regular batches of PVC boards. This design allows the device to automatically adjust the height of the baffle according to the quantity and specifications of the boards, ensuring stable conveying of multiple boards during the process. This effectively solves the limitation of traditional devices that cannot flexibly adapt to different quantities of boards, improving the stability and flexibility of the feeding process.

[0016] 2. When in use, the PVC board feeding device with positioning structure is designed to be adjustable by changing the overall support of the device from a fixed height through the mechanism components. This allows the overall height of the device to be flexibly adjusted according to different conveying needs, improving the flexibility and applicability of the device. Furthermore, in the drive component, a smaller diameter drive gear drives a larger diameter driven gear to rotate. By increasing the output torque of the device, the transmission belt assembly can operate more stably. The overall structure is ingeniously designed and has good practical effect.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please refer to Figures 1-7. This utility model provides a technical solution: a PVC board feeding device with a positioning structure, including a positioning support 1, a drive roller 2, a driven roller 3 and a transmission belt 4. The positioning support 1 is configured with a "U" shaped structure. The drive roller 2 is rotatably installed inside the positioning support 1, and the driven roller 3 is rotatably installed inside the positioning support 1 in an equally spaced arrangement.

[0027] A drive control mechanism 5 is provided on the side of the drive roller 2, a positioning adjustment mechanism 6 is provided on the outside of the transmission belt 4, and a support adjustment mechanism 7 is provided below the positioning support seat 1.

[0028] The drive control mechanism 5 includes a positioning support frame 501, a driven gear 502, a drive gear 503, and a drive motor 504. An "n"-shaped positioning support frame 501 is fixedly installed on the outer side wall of the positioning support seat 1. A support roller inside the drive roller 2 passes through the positioning support seat 1 and is rotatably mounted to the inner side wall of the positioning support frame 501. The driven gear 502 is fixedly installed through the outside of the support roller, and the drive gear 503 is meshed with the side of the driven gear 502. The drive motor 504 is fixedly installed on the outer side wall of the positioning support frame 501. The output end of 504 passes through the positioning support frame 501 and is connected to the side outer wall of the drive gear 503. Both the driven gear 502 and the drive gear 503 are rotatably mounted to the side outer wall of the positioning support 1. The diameter of the driven gear 502 is larger than that of the drive gear 503. Here, the driven gear 502 and the drive gear 503 are set to different diameters. The smaller diameter drive gear 503 drives the larger diameter driven gear 502 to rotate. By increasing the output torque of the device, the transmission belt 4 assembly can run more stably.

[0029] The positioning adjustment mechanism 6 includes a positioning baffle 601, an extension plate 602, a positioning T-shaped strip 603, and a positioning T-shaped groove 604. The positioning baffle 601 is circumferentially fixed to the outer wall of the transmission belt 4. The extension plate 602 is fitted to the upper end of the positioning baffle 601. The positioning T-shaped strip 603 is fixedly installed on the lower outer wall of the extension plate 602. The positioning T-shaped groove 604 is correspondingly provided on the upper outer wall of the positioning baffle 601 for the positioning T-shaped strip 603 to be inserted into. The side of the positioning baffle 601... The outer wall is symmetrically provided with first threaded grooves 605, and the first threaded grooves 605 are in communication with the internal space of the positioning T-shaped groove 604. The side outer wall of the positioning T-shaped strip 603 is provided with two sets of second threaded grooves 606. Fastening bolts 607 are installed inside the first threaded grooves 605 and the second threaded grooves 606. The fastening bolts 607 are embedded in the positioning baffle 601. The fastening bolts 607 are set to be embedded in the positioning baffle 601. The fastening bolts 607 are set to be embedded in the positioning baffle 601 so that the PVC board will not be scratched when it is actually transported.

[0030] The support adjustment mechanism 7 includes piston columns 701, a support box 702, a support base 703, and a crossbar 704. Two sets of piston columns 701 are symmetrically arranged on the bottom outer wall of the positioning support base 1. The bottom ends of the piston columns 701 are slidably installed inside the support box 702. The support base 703 is fixedly installed on the bottom outer wall of the support box 702. A crossbar 704 is connected between the two sets of support bases 703 on the same side. Positioning threaded grooves 705 are evenly spaced through the side outer wall of the support box 702. The piston columns 701... A threaded groove 706 is provided through the outer wall of the side near the bottom. A positioning bolt 707 is installed inside the positioning threaded groove 705 and the threaded groove 706. The rotating end of the positioning bolt 707 is located on the outside of the support box 702. An anti-slip strip is fixedly installed circumferentially on the outer wall of the side where the rotating end of the positioning bolt 707 is located. The design of the anti-slip strip increases the contact friction, so that the user can rotate the positioning bolt 707 more conveniently and stably when operating the device, and it is not easy to slip off.

[0031] Working principle: Refer to Figures 1-3 in the instruction manual. When the entire drive device needs to be operated to feed PVC boards, simply turn on the drive motor 504. When the drive motor 504 is turned on, its output end will rotate, which will automatically drive the drive gear 503 to rotate, which in turn will drive the driven gear 502 to rotate. The driven gear 502 will then automatically drive the drive roller 2 to rotate. Subsequently, the drive roller 2 will automatically drive the transmission belt 4 to rotate, which in turn will drive the driven roller 3 to rotate. Here, the driven roller 3 provides auxiliary support for the transmission belt 4.

[0032] Referring to Figures 4 and 5 in the instruction manual, when the aforementioned transmission belt 4 is in operation, it will automatically drive multiple sets of positioning baffles 601 to drive synchronously. Thus, when actually transporting PVC boards, the board can be placed directly in the middle of two adjacent sets of positioning baffles 601 for smooth transport. When transporting a large number of PVC boards, the stability of the device for transporting materials can be improved by raising the positioning baffles 601. When raising the positioning baffles 601, firstly, the extension plate 602 needs to be adjusted to a suitable position and then its bottom positioning T-shaped strip 603 is inserted into the inside of the positioning T-shaped groove 604. When the positioning T-shaped strip 603 moves to the bottom of the positioning T-shaped groove 604, the first threaded groove 605 and the second threaded groove 606 are in an overlapping state. Then, the fastening bolt 607 is directly passed through the first threaded groove 605 and screwed to the bottom of the second threaded groove 606. This completes the installation process of the extension plate 602.

[0033] Referring to Figures 6 and 7 in the instruction manual, when it is necessary to adjust the height of the overall support feet of the device according to the height of the conveyor table, the positioning bolt 707 should first be unscrewed from the inside of the positioning threaded groove 705, and then the piston column 701 will change from the locked state to the movable state. Then, the positioning support seat 1 should be lifted directly upwards, and the movement of the positioning support seat 1 will automatically drive the piston column 701 to slide inside the support box 702. When the piston column 701 moves to the appropriate height, the positioning bolt 707 should be passed through the corresponding positioning threaded groove 705 and screwed to the bottom of the mating threaded groove 706 to complete the overall adjustment and installation of the device.

[0034] It should be noted that the aforementioned drive motor 504 can be powered by existing operating techniques, whether by using a power supply component or by an external wire. These are all conventional operating techniques and will not be described in detail here.

[0035] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
