Description

Technical Field

[0001] This application relates to the field of wood panel processing technology for log cabins, specifically an extension frame for the production of log cabin panels. Background Technology

[0002] Log cabins are constructed by splicing together multiple wooden planks. When processing these planks, due to the varying heights of the workbenches on the processing equipment, extension racks are needed to support the planks. For example, as shown in Publication No. CN218285943U, an extension rack for wood processing requires workers to simultaneously turn handwheels with both hands to adjust the support rollers up and down. This method is quite laborious, and this type of extension rack can only support the planks, resulting in poor functionality. Therefore, this application proposes an extension rack for log cabin plank production to solve this problem. Summary of the Invention

Detailed Implementation

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 1 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0017] Please see Figure 1-3This application provides a technical solution for an extension frame for the production of wooden planks for wooden houses: an extension frame for the production of wooden planks for wooden houses includes a support frame 1, the support frame 1 includes a side frame 2, a first connecting plate 3 and a second connecting plate 4, the support frame 1 is in the shape of "A", and there are two support frames 1, the two support frames 1 are connected by the first connecting plate 3 and the two second connecting plates 4, and the first connecting plate 3 is set above the second connecting plate 4.

[0018] Specifically, the first connecting plate 3 and the second connecting plate 4 are both fixed to the side frame 2 by bolts. The two side frames 2 can be connected together by the first connecting plate 3 and the second connecting plate 4, which can improve the stability of the support frame 1.

[0019] Furthermore, the bottom of the side frame 2 is provided with a base plate 5, and the bottom of the base plate 5 is provided with two casters 6.

[0020] Specifically, the base plate 5 is fixed to the side frame 2 with bolts, and the caster wheel 6 is fixed to the base plate 5 with bolts. The caster wheel 6 has a self-locking function.

[0021] Two lead screws 7 are vertically mounted on the support frame 1, and the lead screws 7 are connected to the support frame 1 by threads. The bottoms of the two lead screws 7 are connected by a linkage group 8.

[0022] Furthermore, the linkage group 8 includes a guide plate 9, a guide rod 10, a sprocket 11, a chain 12, and a handwheel 13. The bottom of the lead screw 7 is provided with a guide rod 10, and the guide plate 9 is movably connected to the outside of the guide rod 10. The guide plate 9 is mounted on the support frame 1. The bottom of the guide rod 10 is provided with a sprocket 11, and the two sprockets 11 are connected by a chain 12. A handwheel 13 is provided at the bottom of one of the sprockets 11.

[0023] Specifically, there are two guide plates 9, two guide rods 10, and two sprockets 11. The guide plate 9 is fixed in the side frame 2 by bolts. The guide rod 10 passes through the guide plate 9 and is movably connected to the guide plate 9, so that the guide rod 10 can rotate or slide along the guide plate 9. The guide plate 9 can guide the guide rod 10 and improve the stability of the movement of the lead screw 7.

[0024] With this configuration, by turning the handwheel 13, one of the sprockets 11 transmits power through the chain to the other sprocket 11, which in turn drives the two guide rods 10 to rotate, thereby causing the lead screw 7 to rotate. Since the lead screw 7 is connected to the side frame 2 by a thread, the lead screw 7 can move up and down along the side frame 2, thereby adjusting the height of the support roller 16.

[0025] Furthermore, a sleeve 26 is provided on the outside of the lead screw 7, and the sleeve 26 is located between the linkage group 8 and the support frame 1.

[0026] Specifically, the sleeve 26 protects the lead screw 7, preventing dust and other debris from contaminating it and extending its service life.

[0027] A support plate 14 is rotatably connected to the top of the lead screw 7. A support plate 15 is provided on the support plate 14, and a support roller 16 is rotatably connected to the two support plates 15.

[0028] Specifically, the pallet 15 is fixed to the support plate 14 by bolts, and the support roller 16 is provided to support the plate and assist the plate in moving forward.

[0029] A limiting guide group 17 is provided on one side of the support plate 14. The limiting guide group 17 includes a mounting plate 18, an adjusting plate 19 and a guide roller 20. The mounting plate 18 is provided on one side of the support plate 14. The adjusting plate 19 is provided on the upper surface of the mounting plate 18. The guide roller 20 is provided on the upper end of the adjusting plate 19.

[0030] Specifically, the mounting plate 18 and the base plate of the support plate 14 are connected by two strip plates and fixed to the strip plates by bolts. The guide rollers 20 are used to position and guide the plate.

[0031] Furthermore, the adjusting plate 19 has an adjusting groove 21, the fixing bolt 22 is placed in the adjusting groove 21, and the adjusting plate 19 is fixed to the mounting plate 18 by the fixing nut.

[0032] Specifically, by adjusting the groove 21, the fixing nut can be loosened to adjust the position and angle of the guide roller 20, and then fixed again, thereby guiding and positioning plates of different sizes.

[0033] Furthermore, the guide roller 20 includes a connecting bolt 23, a support block 24, a bearing 25, and a connecting nut. The connecting bolt 23 passes through the adjusting plate 19 from bottom to top. A support block 24 is provided on the outside of the connecting bolt 23. At least two bearings 25 are provided on the upper surface of the support block 24, and the bearings 25 are fitted on the connecting bolt 23. The upper surface of the bearings 25 is fixed to the connecting bolt 23 by the connecting nut.

[0034] Specifically, there are five bearings 25, which are used to guide and position the sheet metal.

[0035] In use: Move the device to a suitable position, then lock the caster wheel 6. By turning the handwheel 13, one of the sprockets 11 transmits power to the other sprocket 11 through the chain, which drives the two guide rods 10 to rotate, thereby causing the lead screw 7 to rotate. Since the lead screw 7 is connected to the side frame 2 by a thread, the lead screw 7 can move up and down along the side frame 2, thereby adjusting the height of the support roller 16.

[0036] Subsequently, the fixing nut can be loosened, and the guide roller 20 can be pulled to make the adjusting plate 19 and the adjusting groove 21 rotate or stretch around the fixing bolt 22, thereby adjusting the position and angle of the guide roller 20. Then the fixing nut can be tightened, and the bearing 25 on the guide roller 20 will position and guide the plate.

[0037] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
