Description

Technical Field

[0001] This utility model belongs to the field of packaging wooden box production technology, specifically relating to a packaging wooden box production cutting device. Background Technology

[0002] Wooden crates are wooden containers used for transporting and protecting goods, widely used in industry, agriculture, electronic equipment, and machinery. Their core function is to protect goods from damage caused by impact, vibration, moisture, or compression during transportation. Precisely cutting the planks to the designed dimensions is a crucial step in the production of wooden crates.

[0003] Chinese patent document CN217476145U discloses a clean cutting device for processing wooden boxes for packaging. When the worker feeds the wooden board from the feed inlet, the wooden board moving with the conveyor belt can push the pressing block hinged at the feed inlet of the dust hood to rotate in the direction of the saw disc. The pressing block overlapping the wooden board can apply a downward pressure perpendicular to the surface of the conveyor belt to the wooden board under the action of gravity, so that the wooden board is not easy to deviate during the cutting process.

[0004] However, in the existing technology, the reliance on conveyor belt friction and rigid pressing blocks for positioning has defects such as insufficient positioning stability and easy to cause scratches on the surface of the wooden board. Therefore, a cutting device for packaging wooden box production is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a cutting device for producing packaging wooden boxes.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A packaging wooden box production cutting device includes a feeding component that can laterally convey board material placed in the device, a cutting component that can cut the board material is provided above the feeding component, and a limiting component that can ensure cutting accuracy while avoiding mechanical damage to the board material is also provided above the feeding component.

[0008] The cutting assembly includes a longitudinal shift seat movably installed in the feeding assembly, a carrier movably installed on the longitudinal shift seat, and guide rods movably connected to both sides of the longitudinal shift seat;

[0009] The limiting assembly includes a main limiting component that can apply pressure to the sheet metal and adjust its cutting position, a transmission component that enables the carrier to be linked with the main limiting component, and a secondary limiting component that can cooperate with the main limiting component to further ensure the cutting accuracy of the sheet metal.

[0010] The main limiting component includes a longitudinal frame located in front of the longitudinal frame, a lifting frame movably installed on both sides of the longitudinal frame, a pressure roller movably connected to the front of the lifting frame, and an electric push rod with a telescopic end fixedly connected to the longitudinal frame inside the longitudinal frame.

[0011] Preferably, the transmission component includes a slider disposed behind the longitudinal transfer frame, and a damping rod is disposed between the frame and the slider.

[0012] Preferably, the secondary limiting component includes a U-shaped frame fixedly installed inside the front side of the feeding assembly, and multiple vertical cylinders are movably installed inside the U-shaped frame.

[0013] Preferably, the longitudinal sliding seat is slidably connected to the carrier frame, and both the longitudinal sliding seat and the longitudinal sliding frame are slidably connected to the guide rod.

[0014] Preferably, the longitudinal shift frame and the slider are slidably connected to the lifting frame, and the lifting frame is rotatably connected to the pressure roller.

[0015] Preferably, both the carrier and the slider are rotatably connected to the damping rod.

[0016] Preferably, the damping rod has an electromagnetic lock.

[0017] Preferably, the U-shaped frame is rotatably connected to the vertical cylinder.

[0018] The beneficial effects of this utility model are as follows: by setting pressure rollers on both sides of the longitudinal shift seat, which can move longitudinally with the longitudinal shift seat, rise and fall with the carrier frame, rotate, and move longitudinally independently under the action of electric push rods, the pressure rollers, in conjunction with the secondary limiting parts, can ensure the precise positioning of the sheet metal during the cutting process, and can effectively reduce material surface damage by replacing traditional sliding friction with rolling contact, thus taking into account both the requirements of processing accuracy and material protection.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0030] like Figures 1-5 As shown, a packaging wooden box production cutting device includes a feeding component 1 that can horizontally convey board material placed in the device, a cutting component 2 that can cut the board material is provided above the feeding component 1, and a limiting component 3 that can ensure cutting accuracy while avoiding mechanical damage to the board material is also provided above the feeding component 1.

[0031] In this embodiment: the feeding assembly 1 includes a frame 101, a plurality of idler rollers 102 are movably installed inside the frame 101, a protective frame 103 is fixedly connected to the front side of the frame 101, a shaft seat 104 is fixedly installed inside both sides of the protective frame 103, a rotating shaft 105 is movably connected between the shaft seats 104, a motor 106 is fixedly connected to one end of the rotating shaft 105, a driven bevel gear 107 is fixedly connected to the front end of the idler roller 102, and a driving bevel gear 108 is fixedly connected to the outer side of the rotating shaft 105 on one side of the driven bevel gear 107;

[0032] The bearing seat 104 is rotatably connected to the rotating shaft 105, and the driven bevel gear 107 is meshed with the driving bevel gear 108.

[0033] The frame 101 provides mounting positions for components such as idler rollers 102, protective frames 103, longitudinal hydraulic cylinders 203, guide rods 204, and U-shaped frames 307. Idler rollers 102, which are movably installed in the frame 101, carry the sheet material to be cut and transport it laterally after rotation. The rotating shaft 105 is installed in the protective frame 103 through the bearing seat 104, so that the rotating shaft 105 can synchronously transmit the rotation of the output end of the motor 106 to each idler roller 102 through the driving bevel gear 108 and the driven bevel gear 107.

[0034] In this embodiment: the cutting assembly 2 includes a longitudinal shift seat 201 movably installed in the feeding assembly 1, a carrier frame 202 movably installed on the longitudinal shift seat 201, a longitudinal hydraulic cylinder 203 fixedly connected to the rear of the longitudinal shift seat 201, a guide rod 204 provided between the frame 101 and the longitudinal shift seat 201, a vertical hydraulic cylinder 205 with its telescopic end fixedly connected to the carrier frame 202 fixedly installed in front of the longitudinal shift seat 201, and a cutting machine body 206 fixedly installed at the front end of the carrier frame 202;

[0035] The longitudinal shift seat 201 is slidably connected to the carrier 202, the longitudinal shift seat 201 is slidably connected to the guide rod 204, and the carrier 202 is rotatably connected to the damping rod 306;

[0036] The longitudinal shift seat 201 is installed in the frame 101 via the guide rod 204 whose center line is parallel to the idler roller 102, so that the longitudinal shift seat 201 can move longitudinally in the frame 101 after the longitudinal hydraulic cylinder 203 is run. The height of the carrier 202 on which the cutting machine body 206 is installed is adjusted by the vertical hydraulic cylinder 205. The cutting machine body 206, after running, contacts the plate material passing below it and cuts the plate material.

[0037] In this embodiment: the limiting component 3 includes a main limiting component that can apply pressure to the plate and adjust its cutting position, a transmission component that can link the carrier 202 with the main limiting component, and a secondary limiting component that can cooperate with the main limiting component to further ensure the cutting accuracy of the plate.

[0038] The main limiting component includes a longitudinal frame 301 located in front of the longitudinal shift seat 201, a lifting frame 302 movably installed on both sides of the longitudinal frame 301, a pressure roller 303 movably connected to the front of the lifting frame 302, an electric push rod 304 with its telescopic end fixedly connected to the longitudinal frame 301 fixedly installed inside the longitudinal shift seat 201, a transmission component including a slider 305 located behind the longitudinal frame 301, a damping rod 306 provided between the carrier frame 202 and the slider 305, and a secondary limiting component including a U-shaped frame 307 fixedly installed in front of the feeding assembly 1, and multiple vertical cylinders 308 movably installed inside the U-shaped frame 307.

[0039] The longitudinal transfer frame 301 is slidably connected to the guide rod 204. The longitudinal transfer frame 301 and the slider 305 are both slidably connected to the lifting frame 302. The lifting frame 302 is rotatably connected to the pressure roller 303. The slider 305 is rotatably connected to the damping rod 306. The damping rod 306 has an electromagnetic lock. The U-shaped frame 307 is rotatably connected to the vertical cylinder 308.

[0040] The lifting frame 302, which is rotatably connected to the pressure roller 303, is installed via the longitudinal transfer frame 301, which can move longitudinally along the guide rod 204 after the electric actuator 304 has been moved. This allows the lifting frame 302 to be vertically raised and lowered by external force. The pressure roller 303, located in front of the longitudinal transfer frame 301 and having two different outer diameter specifications, contacts the upper and rear sides of the sheet metal placed within the device after movement. The height change of the carrier frame 202 is redirected via the slider 305 and damping rod 306, and then transmitted to the lifting frame 302, which moves longitudinally with the longitudinal transfer frame 301. 2. The damping rod 306 with an electromagnetic lock can adjust and maintain the distance between the carrier 202 and the lifting frame 302 by changing and locking the length of its telescopic end. The damping rod 306 can also significantly reduce the impact of the vibration generated by the operation of the cutting machine body 206 on the height of the lifting frame 302. Multiple vertical cylinders 308 are installed with their center lines orthogonal to the center line of the roller 102 through the U-shaped frame 307. The vertical cylinders 308, which are rotatable and have an outer diameter that varies within a certain height range, contact the front side of the sheet material placed in this device.

[0041] Working principle: When this device is installed for cutting in the production of wooden boxes for packaging, after the board is placed on the support roller 102, it can be pushed to move the board from one side of the device to below one of the pressure rollers 303. After the movement is completed, according to the longitudinal position of the board to be cut, through the coordinated operation of the longitudinal hydraulic cylinder 203, the vertical hydraulic cylinder 205, the electric push rod 304, and the damping rod 306, the board on the support roller 102 is pressed against the vertical cylinder 308 on the front side, the front of the larger part of the pressure roller 303 on the rear side, and the outer side of the smaller part of the pressure roller 303 on the upper side. The cutting edge of the cutting blade of the cutting machine body 206 coincides with the longitudinal position of the board to be cut, and the lowest edge of the cutting edge should be lowered to a suitable height relative to the board. In addition, when the lifting frame 302 drives the pressure roller 303 to the limit position, the damping rod 306 should, through its own length change and re-locking, offset the effect of the reduction in the height of the carrier frame 202 on the lifting frame 302 and lock the height of the lifting frame 302.

[0042] After the above adjustments are completed, the motor 106 and the cutting machine body 206 can be started to transport and cut the sheet material laterally.

[0043] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
