DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-Figure 6 The present embodiment provides a rubber wood processing extension device, comprising a base 1, a workbench 2 is arranged on the top of the base 1, a push plate assembly 4 located at the front end of the workbench 2 is arranged on the base 1 through a bracket 3, and a baffle assembly 5 is arranged on the base 1 at the rear end of the workbench 2, a hanger 6 parallel to the workbench 2 is arranged above the workbench 2, a connecting plate 7 inclined toward the advancing direction of the rubber wood is hinged on the lower side of the hanger 6 through a U-shaped plate 61, a pressing roller 8 is arranged at the bottom of the connecting plate 7, and a pressing assembly 9 is hinged between the connecting plate 7 and the hanger 6.

[0025] In the utility model, two short boards processed with comb teeth are sequentially placed on the workbench 2 on the top of the base 1, the comb tooth ends of the two short boards are coated with glue, and then the push plate assembly 4 on the bracket 3 is driven, and the push plate assembly 4 pushes the two short boards until the rear end of one of the short boards is against the baffle assembly 5, and the push plate assembly 4 makes the two short boards tightly connected. In the process of the push plate assembly 4 pushing the short boards, the short boards pass through the pressure roller 8 at the lower end of the connecting plate 7 when moving, and the pressure roller 8 is pressed on the short boards under the action of the pressing assembly 9, which can avoid the phenomenon of warping at the connection of the wood and prevent the wood from arching, thereby ensuring that the two short boards that are extended can be tightly connected.

[0026] Specifically, refer to Figure 2 and Figure 3The clamping assembly 9 includes a support rod 91 hinged to the hanger 6 through a first connecting member 95, a movable rod 93 is sleeved on the support rod 91 through a connecting groove 92, a spring 94 is arranged between the top of the movable rod 93 and the inner wall of the connecting groove 92, and the bottom of the movable rod 93 is hinged to the connecting plate 7 through a second connecting member 96. The sleeved movable rod 93 can be extended and retracted on the connecting groove 92 of the support rod 91, and cooperates with the spring 94 to provide elastic force, so that the clamping assembly 9 can be extended and retracted when plates of different thicknesses pass through the pressing roller 8, ensuring that there is space between the pressing roller 8 and the workbench 2 for the plates to pass through, and at the same time, the elastic force of the spring 94 also presses the pressing roller 8 downward, ensuring that the pressing roller 8 can always be pressed on the plate, so that the lateral thrust on the plate is more dispersed, thereby avoiding the phenomenon of plate arching.

[0027] Specifically, refer to Figure 2 and Figure 4 The pressure roller 8 includes a roller shaft 81, a rubber sleeve 82 is provided on the outside of the roller shaft 81, and shafts 83 are provided at both ends of the roller shaft 81. The roller shaft 81 is rotatably mounted on the bottom of the connecting plate 7 through the shaft 83, so as to achieve guidance, ensuring that the extended sheet can smoothly pass through the lower side of the pressure roller 8, and the rubber sleeve 82 provides a buffer to prevent the pressure roller 8 from crushing the sheet when the pressure roller 8 presses the extended sheet.

[0028] It should be noted that there are several pressing rollers 8, and the several pressing rollers 8 are evenly arranged below the hanger 6 along the length direction of the hanger 6 through the connecting plate 7. The several pressing rollers 8 can make the lateral thrust of the push plate assembly 4 on the board offset the pressure of the pressing rollers 8, so that the lateral thrust is more dispersed, avoiding the phenomenon of the board arching caused by the concentrated thrust, thereby improving the safety of the wood when splicing.

[0029] Among them, the hanger 6 is fixed above the workbench 2 through a plurality of positioning plates 62. The positioning plates 62 are provided with screw holes 63. The hanger 6 is fixed through the positioning plates 62. At the same time, the positioning plates 62 can be used to realize the installation and disassembly of the hanger 6, so that the hanger 6 can be conveniently maintained and repaired.

[0030] Specifically, refer to Figure 1 and Figure 5 The push plate assembly 4 includes a first cylinder 41 fixed to the bracket 3 through a fixing frame 43 and a mounting strip 44, and a push plate 42 is provided on the output end of the first cylinder 41 to slide on the upper side of the workbench 2. The first cylinder 41 is detachably mounted on the bracket 3 through the fixing frame 43 and the mounting strip 44, so that it can be disassembled for maintenance. The first cylinder 41 pushes the push plate 42 to move, and then the push plate 42 is used to push the plate to be extended to make it tightly connected.

[0031] Specifically, refer to Figure 1 and Figure 6The baffle assembly 5 includes a mounting frame 51 mounted on the workbench 2, a second cylinder 52 is arranged on the top of the mounting frame 51, and a material baffle plate 54 is arranged on the output end of the second cylinder 52 through a fixed seat 53. When two short boards are connected, the second cylinder 52 pushes the material baffle plate 54 on the fixed seat 53 to block the rear end of the workbench 2, thereby providing a support point for the short boards, and the two short boards can be tightly connected in cooperation with the push plate assembly 4. After the glue of the two short boards is cured, the second cylinder 52 drives the material baffle plate 54 to rise, and then the two short boards connected together can be pulled out.

[0032] Among them, a slide rail 55 is arranged on the inner side surface of the mounting frame 51, and a slide groove 56 matching with the slide rail 55 is opened on the fixed seat 53. The slide rail 55 and the slide groove 56 perform a guiding role. When the second cylinder 52 is extended and retracted to drive the baffle plate 54 of the fixed seat 53 to move up and down, the fixed seat 53 can slide stably with the cooperation of the slide rail 55 and the slide groove 56, thereby avoiding the phenomenon of the fixed seat 53 being offset and tilted.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
