Description

Technical Field

[0001] This utility model belongs to the field of wooden pallet processing, and in particular relates to a wooden block cutting device. Background Technology

[0002] Wooden pallets are horizontal platform devices used for the assembly, stacking, handling, and transportation of goods and products as unit loads. Made of timber, wooden pallets typically consist of a front panel, a base plate, and padding blocks, forming a stable load-bearing structure that facilitates forklift handling.

[0003] Spacer blocks are generally made from timber, specifically by using a block-cutting device to cut the timber into several equal-sized blocks. When using existing block-cutting devices to cut timber, the timber is first placed on the processing position of the machine according to requirements. A cylinder is then used to push the timber a short distance towards the cutting disc, and a pressure seat presses the timber at the cutting position. The cutting disc then cuts the timber into blocks. While this method can produce spacer blocks, only the cutting position of the timber is pressed during the cutting process, causing slight wobbling and resulting in poor cutting quality. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a timber cutting device, which aims to solve the problem that the timber will shake slightly during the process of existing timber cutting devices, resulting in poor cutting quality.

[0005] The present invention adopts the following technical solution:

[0006] The timber cutting device includes a machine base with a machine cover. A fixed base is located on one side of the machine base, and a pre-tightening assembly is located on the other side. A pressing mechanism is located at the front end of the fixed base. A liftable cutting disc is located inside the machine base, directly opposite the pressing mechanism. A long slot is opened at the top of the fixed base, and a moving module is located inside the fixed base. The drive end of the moving module extends out of the long slot and is provided with a push seat. The push seat is located between the fixed base and the pre-tightening assembly. The pre-tightening assembly includes a rotating shaft and a column respectively rotatably mounted on the machine base. A clamp is provided on the rotating shaft via a torsion spring. A slot is opened on the back of the clamp. A rotating block is rotatably mounted in the slot via a short shaft. A sliding opening is opened at the other end of the rotating block. A C-shaped handle is provided on the column, and the upper part of the C-shaped handle is located in the sliding opening.

[0007] Furthermore, the pressing mechanism includes a pressing frame, a pressing seat is slidably provided inside the pressing frame, and the pressing seat is a cavity. An adsorption tube is connected to the top of the pressing seat. The adsorption tube extends out of the machine cover and is connected to the adsorption port of the negative pressure machine. A pressing cylinder is provided at the top of the pressing frame, and the drive shaft of the pressing cylinder is connected to the pressing seat.

[0008] Furthermore, the side wall of the lower pressure frame has a pair of left and right sliding grooves, and the left and right sides of the pressure seat are provided with sliding rods. The sliding rods pass through the sliding grooves on the same side and are provided with retaining sleeves.

[0009] Furthermore, the machine platform has a cutting groove inside the upper and lower pressure frame, and the cutting disc is located inside the cutting groove.

[0010] Furthermore, the machine tool is equipped with a cutting frame, on which a lifting frame is slidably mounted. The lifting frame is equipped with a cutting disc and a cutting motor, wherein the cutting disc is rotatably mounted and the cutting motor is fixedly mounted. The drive shafts of the cutting motor and the cutting disc are respectively equipped with a driving wheel and a driven wheel. A cutting belt is fitted between the driving wheel and the driven wheel. A lead screw is rotatably mounted on the cutting frame, and a threaded sleeve is fitted on the lead screw. The threaded sleeve is connected to the lifting frame. A lifting wheel is located at the bottom of the lead screw. The cutting frame is equipped with a lifting motor, and the drive shaft of the lifting motor is equipped with a drive wheel. A lifting belt is fitted between the drive wheel and the lifting wheel.

[0011] The beneficial effects of this utility model are as follows: First, the timber is placed at the processing position, and the left and right sides of the timber are limited by the fixing seat and the pre-tightening component. Then, the pushing seat pushes the timber forward a short distance, and the pressing mechanism presses the front end of the timber. Finally, the rotating cutting disc moves upward to complete the cutting and then resets. The pressing mechanism releases the pressure on the timber. Then, the pushing seat continues to push the timber forward a short distance, and the cutting disc is ready to cut the timber into pads again. During the above cutting process, the pushing seat can continuously push the timber forward, which can improve the cutting effect. Moreover, the distance that the pushing seat pushes the timber forward each time is equal, which ensures that all pads have the same specifications after production. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0017] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0018] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0019] Combination Figure 1-3 As shown, the timber cutting device includes a machine base 1, a machine cover 2 on the machine base 1, a fixed seat 3 on one side of the machine base 1, and a pre-tightening assembly 4 on the other side. A pressing mechanism is provided at the front end of the fixed seat 3. A liftable cutting disc 6 is provided inside the machine base 1, directly opposite the pressing mechanism. A long slot 7 is opened at the top of the fixed seat 3. A moving module 5 is provided inside the fixed seat 3. The driving end of the moving module 5 extends out of the long slot 7 and is provided with a pushing seat 8. The pushing seat 8 is located between the fixed seat 3 and the pre-tightening assembly 4. The pre-tightening assembly 4 includes a rotating shaft 41 and a column 42 respectively rotatably mounted on the machine base 1. A clamp 43 is provided on the rotating shaft 41 via a torsion spring (covered in the figure). A slot 44 is opened on the back of the clamp 43. A rotating block 46 is rotatably provided in the slot 44 via a short shaft 45. A sliding opening 47 is opened at the other end of the rotating block 46. A C-shaped handle 48 is provided on the column 42. The upper part of the C-shaped handle 48 is located in the sliding opening 47.

[0020] Wooden pallets are made of timber and generally consist of a panel, a base, and pads to form a stable load-bearing structure that facilitates forklift handling. The pads are also made of timber and can be cut into several equal-sized pads using this cutting device.

[0021] When using this cutting device to cut timber into several equal-sized blocks, the timber is first placed in the processing position between the fixed seat and the pre-tightening component. The fixed seat and the pre-tightening component limit the left and right sides of the timber. Then, driven by the moving module, the pusher pushes the timber forward a short distance. The pressing mechanism presses down on the front end of the timber. Finally, the rotating cutting disc moves upward to complete the cutting and resets, and the pressing mechanism releases the pressure on the timber. Immediately afterwards, the pusher continues to push the timber forward a short distance, and the cutting disc prepares to cut the timber into blocks again. During the cutting process, the pusher can continuously push the timber forward, which improves the cutting effect. Furthermore, the distance the pusher pushes the timber forward each time is equal, ensuring that all blocks produced are of the same size. Since the moving module is existing technology, it will not be described in detail here.

[0022] Before placing the timber at the processing position, first turn the C-shaped handle outwards. As the C-shaped handle rotates outwards, it causes the clamp to rotate outwards, creating a clearance. During this process, the torsion spring deforms. Then, place the timber between the fixed seat and the clamp as required, and release the C-shaped handle. Under the action of the torsion spring, the clamp contacts the timber, and the C-shaped handle returns to its original position under the action of the rotating block. Throughout the entire process of cutting the timber, the clamp remains in contact with the timber, pre-pressing it. The clamp and fixed seat together limit the lateral movement of the timber, making the timber more stable during cutting without affecting the normal pushing of the timber by the pusher.

[0023] As a preferred structure, such as Figure 1-2 as well as Figure 4 The pressing mechanism includes a pressing frame 9, within which a pressing seat 10 is slidably mounted. The pressing seat 10 is a cavity, and an adsorption tube 11 is connected to the top of the pressing seat 10. The adsorption tube 11 extends out of the machine cover and connects to the adsorption port of a negative pressure machine (not shown in the figure). A pressing cylinder 12 is mounted on the top of the pressing frame 9, and the drive shaft of the pressing cylinder 12 is connected to the pressing seat 10. A cutting groove 28 is formed inside the pressing frame 9 on the machine base 1, and the cutting disc 6 is located within the cutting groove 28.

[0024] After the timber is placed in the processing position, the pusher, driven by the moving module, pushes the timber forward a short distance, with the front end of the timber passing through the lower pressure frame. Then, the lower pressure cylinder drives the pressure seat downwards until it presses the timber firmly. The rotating cutting disc moves upwards and cuts the timber. During the cutting process, some dust and other impurities are generated. The negative pressure machine remains operational throughout this process, generating negative pressure and adsorbing these impurities through the suction tube. This prevents excessive dust and lint buildup during cutting. Since the negative pressure machine is not a key component of this device, it will not be described in detail here.

[0025] In the above structure, the side wall of the lower pressure frame 9 has a pair of left and right sliding grooves 14, and the left and right sides of the pressure seat 10 are provided with sliding rods 15. The sliding rods 15 pass through the sliding grooves 14 on the same side and are provided with retaining sleeves 16. During the process of the lower pressure cylinder driving the pressure seat to move vertically, the sliding rods slide vertically in the sliding grooves on the same side. During this process, the sliding rods and retaining sleeves play a guiding and limiting role, making the vertical movement of the pressure seat more stable.

[0026] Furthermore, as a preferred structure, such as Figure 3The machine tool 1 is equipped with a cutting frame 17, on which a lifting frame 18 is slidably mounted. The lifting frame 18 is equipped with a cutting disc 6 and a cutting motor 20, wherein the cutting disc 6 is rotatably mounted and the cutting motor 20 is fixedly mounted. The drive shafts of the cutting motor 20 and the cutting disc 6 are respectively equipped with a driving wheel and a driven wheel 22, and a cutting belt is fitted between the driving wheel and the driven wheel 22. A lead screw 23 is rotatably mounted on the cutting frame 17, and a threaded sleeve 24 is fitted on the lead screw 23, which is connected to the lifting frame 18. A lifting wheel 25 is located at the bottom of the lead screw 23. A lifting motor 26 is mounted on the cutting frame 19, and a drive wheel 27 is mounted on the drive shaft of the lifting motor 26. A lifting belt is fitted between the drive wheel 27 and the lifting wheel 25. The driving wheel, lifting belt, and cutting belt are not shown in the figure.

[0027] During the timber cutting process, the cutting disc remains rotating. Specifically, the cutting motor drives the drive wheel, which in turn rotates under the linkage of the cutting belt. Once the timber is pressed down by the pressure seat, the lifting motor drives the drive wheel to rotate, and under the linkage of the lifting belt, the lead screw rotates. The lead screw sleeve moves the lifting frame a short distance along the height of the lead screw, allowing the cutting disc to pass through the cutting groove until the timber is cut into pieces. Afterward, the lifting motor reverses, the cutting disc returns to its original position, and it awaits the next cutting operation.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
