Description

Technical Field

[0001] The utility model relates to the technical field of machine tool loading equipment, in particular to a machine tool loading positioning device for door leaf processing. Background Art

[0002] With the rapid development of modern furniture manufacturing, door panels, as an important part of furniture, have a significant impact on the overall production of the enterprise due to their processing quality and efficiency. In the process of door panel processing, machine tools, especially double-sided saws, are generally used to accurately cut the door panels. The processing accuracy and efficiency are directly related to the final quality of the door panels. The feeding accuracy of the door panels has also become one of the important factors in improving the overall processing accuracy.

[0003] Deficiencies of existing technology:

[0004] In the existing double-sided sawing door leaf processing process, the loading and positioning of the door leaf mainly relies on manual operation. Specifically, the door leaf is conveyed to the saw table by a conveyor belt, and then the staff stands on both sides of the conveyor belt to manually adjust and correct the tilted door leaf, so that the four sides of the door leaf are respectively kept horizontal and vertical with the conveyor belt, thereby ensuring that the door leaf will not be parked on the saw table in a tilted posture. However, this loading method still has many shortcomings. First of all, in the traditional loading process, if the placement of the door leaf needs to be corrected, due to the heavy weight of the door leaf, the operation is inconvenient and the machine needs to be stopped, which affects the overall transmission efficiency. Secondly, long-term manual operation will also increase the labor intensity of the staff, reduce work efficiency, and cannot meet the needs of large-scale and high-efficiency production. Utility Model Content

[0011] A small speed-changing wheel is symmetrically arranged on the upper end surface of the base through a bracket and meshedly connected with the lower end of the fixed gear. A large speed-changing wheel is arranged on one side of the small speed-changing wheel, and the teeth of the large speed-changing wheel match the movable gear.

[0012] Preferably, a plurality of protrusions are arranged on the side wall adjacent to the fixed gear, a groove matching the contour of the protrusion is opened on the side wall of the fixed gear, and the movable gear and the fixed gear rotate synchronously through the docking of the protrusion and the groove.

Compared with the traditional manual measurement and adjustment of material feeding by staff, it does not require shutdown operation, has higher transmission efficiency, and also reduces the labor intensity of staff, and can meet the large-scale and high-efficiency production needs.

[0030] See also Figure 1-5As shown, the utility model provides a technical solution of a machine tool loading and positioning device for door leaf processing: a machine tool loading and positioning device for door leaf processing, comprising a base 1, two roller groups 2 are symmetrically mounted on the upper end surface of the base 1 through a bracket, and a conveyor belt 3 for conveying door leaves is mounted on the two roller groups 2, and a correction driving mechanism 4 for driving the door leaf to be conveyed and corrected is mounted on one end of the two roller groups 2, and a controller 5 is also mounted on the upper end surface of the base 1. The correction driving mechanism 4 includes a transmission shaft 401, a mounting frame 403, a sliding rod 406 and a small speed change wheel 410. The transmission shaft 401 is respectively mounted on one end of the two roller groups 2, and a motor 402 is mounted on the bracket on one side of the two roller groups 2, and the output end of the motor 402 is connected to the end of the transmission shaft 401. The mounting frame 403 is fixedly mounted on the upper end surface of the base 1 and located between the transmission shafts 401, and a transmission box 404 is rotatably connected in the mounting frame 403, and an electromagnet 405 is symmetrically mounted on the inner mounting plate of the transmission box 404. The sliding rod 406 is slidably connected to the two ends of the transmission box 404. The interior of the sliding rod 406 is embedded with a permanent magnet 407 matching the electromagnet 405. The end of the sliding rod 406 is also installed with a moving gear 408. The end of the transmission shaft 401 adjacent to the transmission box 404 is installed with a fixed gear 409 matching the moving gear 408. The diameter of the moving gear 408 is smaller than the fixed gear 409. The small speed change wheel 410 is symmetrically installed on the upper end surface of the base 1 through a bracket and meshed with the lower end of the fixed gear 409. A large speed change wheel 411 is installed on one side of the small speed change wheel 410. The teeth of the large speed change wheel 411 match the moving gear 408. When the moving gear 408 and the fixed gear 409 are in close transmission, the large speed change wheel 411 does not mesh with the moving gear 408. When the loading and positioning device needs to transport the wooden door to the double-sided saw, the motor 402 is started and the two electromagnets 405 are energized. The electromagnets 405 generate a repulsive force on the permanent magnets 407, so that the moving gear 408 and the fixed gear 409 fit together and can keep rotating synchronously. The motor 402 drives the transmission shaft 401 on one side to rotate. The transmission shaft 401 drives the transmission box 404 to rotate through the fixed gear 409, the moving gear 408 and the sliding rod 406 at the end. The other end of the transmission box 404 drives another transmission shaft 401 to rotate with the same structure. At this time, the two roller groups 2 start to rotate, and the conveying speeds of the conveyor belts 3 on both sides of the base 1 remain consistent. The stacking box 8 first releases a door leaf to the feeding end of the conveyor belt 3, and the door leaf is transmitted on the conveyor belt 3.When the controller 5 detects that the door leaf is tilted on the conveyor belt 3, the electromagnet 405 on the front side of the door leaf changes the direction of the current under the control of the controller 5, generates attraction to the matching permanent magnet 407, and sucks the sliding rod 406 into the transmission box 404. At this time, the moving gear 408 on the sliding rod 406 is separated from the fixed gear 409 and re-engaged with the large speed change wheel 411. Due to the change in the transmission ratio, the running speed of the transmission shaft 401, the roller group and the corresponding conveyor belt 3 on this side is lower than that on the other side, so that the front side of the door leaf moves relatively backward and the rear side moves relatively forward, achieving the purpose of correction. This adjustment method only adjusts the transmission ratio of the transmission shaft 401 on both sides. Through the correction drive mechanism 4, the effect of automatic online correction of the offset door leaf during the feeding process is achieved, so that the door leaf is automatically aligned on both sides before entering the double-sided saw. Compared with the traditional manual measurement and adjustment of the feeding by the staff, it does not require shutdown operation, the transmission efficiency is higher, and the labor intensity of the staff is reduced, which can meet the large-scale and high-efficiency production needs.

[0031] Several protrusions 4081 are installed on the side wall of the side adjacent to the fixed gear 409, and a groove 4091 matching the profile of the protrusion 4081 is opened on the side wall of the fixed gear 409. When the moving gear 408 and the fixed gear 409 need to maintain synchronous transmission, the protrusion 4081 can be embedded in the groove 4091. When the moving gear 408 needs to mesh with the large speed change wheel 411, the protrusion 4081 is pulled out from the groove 4091, and the moving gear 408 is separated from the fixed gear 409. Through the cooperation of the protrusion 4081 and the groove 4091, the fast docking and separation of the moving gear 408 and the fixed gear 409 is realized, and such a docking mode is more stable and reliable in combination with the magnetic force of the electromagnet 405, and the moving gear 408 and the fixed gear 409 will not be separated due to large torque and insufficient magnetic force, thereby improving the stability of the overall operation.

[0032] The cross section of the sliding connection part between the sliding rod 406 and the transmission box 404 is rectangular, and the rectangular cross section can ensure that the sliding rod 406 and the transmission box 404 are synchronously and stably transmitted without slipping and idling.

[0033] Photoelectric sensors 6 for detecting the placement status of the door leaf on the conveyor belt 3 are symmetrically installed on both sides of the upper end surface of the base 1. The photoelectric sensors 6 can accurately detect whether the door leaf is tilted on the conveyor belt 3 and send the data to the controller 5.

[0034] The controller 5 is electrically connected to the electromagnet 405 and the photoelectric sensor 6 through wires. After receiving the signal from the photoelectric sensor 6 through the wires, the controller 5 can determine by calculation which electromagnet 405 needs to adjust the current direction and the time for the current direction to change, thereby ensuring that the door leaf can be corrected in one correction.

[0035] A plurality of tensioning rollers 7 for tensioning the conveyor belt 3 are installed at the lower ends of the two roller groups 2. The tensioning rollers 7 can ensure that the conveyor belt 3 fits tightly with the lower ends of the rollers in the two roller groups 2.
