Description

Technical Field

[0001] This utility model relates to the field of wood processing equipment technology, and in particular to a wood slicing machine with adjustable slicing gap. Background Technology

[0002] Logs are long sections of wood cut into certain lengths according to standard or special specifications for size, shape, and quality. Generally, the length of the log is specified to be no more than 12m or 40 feet. They have many uses in construction, furniture, craft carving, and papermaking. For wood processing, wood chips are the most common.

[0003] However, existing wood chippers cannot adjust the gap between the blade rollers when slicing wood, so the size of the wood chips produced is relatively fixed, which is not conducive to diversified production. In addition, existing devices often use traction rollers to guide the logs to contact the blade rollers, but logs that have not yet entered the device are prone to warping, which poses a safety hazard.

[0029] In this embodiment, two movable bases 15 slide on one side of the inner wall of the cutting chamber 13, and driven wheels 19 are rotatably mounted on the top of each movable base 15.

[0030] In this embodiment, a drive wheel 20 is rotatably mounted on the top of each of the two movable bases 15, and a corresponding belt 22 is fitted on each of the two drive wheels 20 and the two driven wheels 19.

[0031] In this embodiment, a motor chamber is provided inside the cutting chamber 13. Two cutting servo motors 21 are fixedly installed on one inner wall of the two motor chambers. The output shafts of the two cutting servo motors 21 are respectively connected to the corresponding drive wheels 20, so that the two cutting servo motors 21 can drive the corresponding drive wheels 20 to rotate.

[0032] In this embodiment, each of the two driven wheels 19 has a snap-fit ​​groove on its top, and a snap-fit ​​metal block 17 is snapped into each of the two snap-fit ​​grooves.

[0034] Working principle: When slicing logs, the worker places the processed logs on the roller conveyor belt 3. The roller conveyor belt 3 moves the logs. The worker starts two limit servo motors 9 via the main control board 2. The two limit servo motors 9 drive the corresponding active bevel gears 7 to rotate. The two active bevel gears 7 drive the same driven bevel gear 6 to rotate. The driven bevel gear 6 drives the planar threaded ring 5 to rotate. The planar threaded ring 5 drives multiple sliding racks 10 to slide. The sliding racks 10 move closer together, causing the corresponding limit rollers 12 to move closer together to clamp the logs. Since the multiple limit rollers 12 are all rotated and mounted on corresponding limit posts 11, once the position is adjusted, it can accommodate logs of similar diameter without frequent adjustments, and it will not affect the movement of the traction roller 14. The logs contact the traction roller 14, and the traction roller 14 pulls the logs. The guide roller 14 moves the log toward the two cutter rollers 18. The main control board 2 starts the rotation of two cutting servo motors 21. The rotation of the two cutting servo motors 21 drives the corresponding drive wheels 20 to rotate. The rotation of the two drive wheels 20 drives the corresponding driven wheels 19 to rotate via the corresponding belts 22. The rotation of the two driven wheels 19 drives the corresponding transmission shafts 16 to rotate. The rotation of the two transmission shafts 16 drives the corresponding cutter rollers 18 to rotate. The two cutter rollers 18 rotate to slice the wood. When it is necessary to adjust the cutting gap, there is no need to stop the machine. The main control board 2 starts the movement servo motor 24. The movement servo motor 24 drives the positive and negative toothed ball screws 23 to rotate. The rotation of the positive and negative toothed ball screws 23 drives the two moving sliders 25 to move. The movement of the two moving sliders 25 drives the corresponding moving bases 15 to move, causing the corresponding cutter rollers 18 to move closer or further apart, thereby achieving the purpose of adjusting the gap.

[0035] The technological advancements of this invention compared to existing technologies are as follows: the gap between the cutter rollers 18 can be adjusted through a set mechanism, thereby adjusting the thickness of the produced wood chips, which increases the practicality of the device. Furthermore, it can limit the logs that have not yet entered the device for cutting, preventing them from shifting or warping, thus increasing the safety and stability of the device.
