Description

A Knife Holder for Paper Tube Cutting Machines with Easy-to-Adjust Spacing

technical field

The utility model relates to a cutter holder for a cutting machine which is easy to adjust the spacing, in particular to a cutter holder suitable for cutting paper tubes.

Background technique

At present, in the paper tube production industry, long paper tubes are generally produced by spiral coiling or flat coiling, and then the long paper tubes are cut into short paper tubes of a certain length according to different application requirements. Industries, such as chemical fiber industrial tubes, film industrial tubes, and printing industrial tubes, have different requirements for the length of paper tubes, which requires frequent adjustment of the blade distance for cutting paper tubes, which needs to be adjusted with a vernier caliper. The adjustment is difficult and efficient. Low.

In the actual production of paper tubes, a knife holder that can quickly adjust the blade is often needed, and the utility model proposes a new knife holder at this point.

Utility model content

The purpose of this utility model is to overcome the deficiencies of the above-mentioned background technology, and provide a paper tube cutting machine tool holder that is easy to adjust the spacing. The tool holder should have the characteristics of manual operation, convenient adjustment, and visible spacing to improve the cutting machine. work efficiency.

The technical solution provided by the utility model is: a cutting machine tool holder that is easy to adjust the distance, including two tool holder seats arranged in parallel and separated by a certain distance and connected as a whole through a connecting block, rotatably positioned at the end of the knife holder seat The blade of the part, the sprocket assembly that transmits the power of the drive shaft to the blade, is characterized in that the tool holder seat is positioned on the tool holder slide table through a guide rail arranged parallel to the axis of the drive shaft, and the tool holder is driven by the rack assembly Move along the rails.

The rack in the rack assembly is arranged parallel to the axial direction of the transmission shaft on the slide table of the tool holder, and the gear matched with the rack is rotatably positioned on the connecting block through the hand wheel shaft.

One end of the handwheel shaft is fixed with a handwheel.

The sprocket assembly includes a large sprocket fixed on the drive shaft, a small sprocket fixed on the cutter shaft and a chain transmitting power between the two sprockets.

Scale marks arranged parallel to the axial direction of the transmission shaft are also made on the said knife rest slide table.

The beneficial effect of the utility model is: adopting the cutter holder of the above-mentioned technical scheme, the operator can adjust the position of the drive shaft direction of the cutter holder only by rotating the handwheel, and read the distance between the blades through the scale on the side of the handwheel, Therefore, it has the characteristics of manual operation, convenient adjustment, and intuitive and visual spacing.

detailed description

Further description will be given below in conjunction with the embodiments shown in the accompanying drawings.

As shown in Figure 1, several cutting machine tool holders 100 are arranged in parallel on the knife holder slide table 1 of the paper tube cutting machine, and a rotatable transmission shaft 2 is positioned on the knife holder slide table through a shaft seat 3, and the transmission shaft 2 is positioned on the knife holder slide table. A large sprocket 10 is installed on the shaft, and the transmission shaft 2 is rotated by external power, and the cutter shaft 8 is driven by a chain to rotate, thereby driving the blade 6 to rotate, which can facilitate the cutting of the paper tube 4.

In the cutter holder of the cutting machine, two parallel blade holders 21 with a certain distance from each other are connected as a whole through the connecting block 14; the cutter shaft 8 equipped with the blade 6 is rotatably positioned on the knife holder swing arm 25 At the end of the sprocket assembly (including the large sprocket fixed on the drive shaft, the small sprocket fixed on the blade shaft and the chain transmitting power between the two sprockets) transmits the power introduced by the drive shaft to blade. In addition, each knife rest seat swing arm is hinged on the knife rest seat through a pin shaft, and the bottom end of the adjusting screw 22 positioned on the knife rest seat is connected with the knife rest seat swing arm through a hinge pin 24; Rotate the nut 23 on the adjusting screw rod of two knife rest seats at the same time and can make the knife shaft move up and down.

The improvement of the utility model is that a guide rail 15 parallel to the axis of the transmission shaft is arranged between the tool holder seat and the tool holder slide table, so that the tool holder seat can slide along the axial direction of the transmission shaft; in addition, a drive tool holder seat is arranged The rack assembly provides the power for the tool holder to slide. The structure of the rack assembly includes a rack 13 and a gear 12 engaged with the rack; the rack is located on the tool holder slide table and is arranged parallel to the axial direction of the transmission shaft; the gear matched with the rack is manually The wheel shaft is rotatably positioned on the connecting block; as can be seen in the figure, the hand wheel shaft passes through the connecting block, one end of which is fixed with the hand wheel 11, and the other end is fixed with a gear. Rotating the hand wheel drives the tool holder to move as a whole to complete the adjustment of the blade spacing. The transmission accuracy of the rack and pinion can reach 0.1mm, and the precision that the distance between the blades can achieve depends on the transmission accuracy of the rack and pinion, so the utility model has higher precision when adjusting the distance.

Figure 4 is a schematic diagram of the cutting state of the embodiment of the utility model; the external power drives the slide table 1 to rotate, so that the tool holder as a whole rotates around the axis 1-1 where the slide table is located, and the blade 6 in high-speed motion approaches the paper tube 4 , to complete the cutting of the paper tube.

The above is only a specific embodiment of the utility model, but the technical characteristics of the utility model are not limited thereto, and any changes or modifications made by those skilled in the art within the scope of the utility model are all covered by the utility model. In the scope of the new patent.
