Description

A mold knife cutting and forming device for the post-absorbing process

technical field

The utility model relates to the technical field of post-molding deep processing of plastic sheet packaging, in particular to a mold cutter cutting and forming device for post-absorbing plastic.

Background technique

At present, there are mainly two ways of cutting and forming equipment for mold knife cutting after blistering:

The first one is to use hydraulic machinery for stamping and cutting. The main disadvantages of this equipment are:

Lower production capacity: first stamp the processed large piece of forming frame material into a small frame material of about 20X20 cm, then manually collect it for temporary storage, and finally manually stack several layers of the small frame material and place it in the die knife for stamping and cutting again, and manually take it out again One-time stamping and automatic separation of a whole sheet or a large area is not possible. Due to the cumbersome process, the production capacity is low. Based on a large sheet or a large area (1.2X0.7m) frame material, the production capacity is about 5 pieces per minute. about.

Poor operation safety: During the stamping process, the operator has to place it constantly, the mold knife has a cutting edge, and if you are not careful, your fingers will be scratched. Injuries are common in the industry; in addition, the small frame will be installed manually When the mold knife is reciprocally placed on the hydraulic machine table, people will be fatigued due to continuous and repetitive work, and their arms will also be injured due to human errors. In the industry, it is generally necessary to equip the punching machine with infrared body protection.

The cost of using the mold knife is high: cutting and forming need to be equipped with a mold knife (female mold) and a punch (male mold), and it takes a lot of time to match the mold each time. If the male and female molds are slightly loose, the mold knife will be scrapped, which will also cause In addition, die knives also need a complete set of stamping punches. It is very difficult to match a large area with a one-to-one layout and a large number of punches, and the cost is also high. This method has not been adopted in the industry. Even if This method can only be applied to about 1/3 of the area of the frame material of 1.2X0.7 meters.

High energy consumption: The minimum power of the hydraulic system motor is above 4KW, which belongs to continuous work.

The labor intensity of the operator is high: during the whole processing process, the workers have to keep turning around, placing them back and forth, and constantly stepping on the foot control switch. The operator is in a tense and busy state during the whole process; It can be cut at one time, and the cutting efficiency is very high, but it is very inconvenient to load and unload, and the loading and unloading efficiency is extremely low, especially after cutting, there are dozens of products that need to be picked up manually, because the weight of the mold knife itself can reach more than 10KG, using Operations such as manual loading and unloading are obviously unrealistic.

The second is to use a transmission belt with a width of about 1.2 meters. There are two pairs of rollers in the middle. The mold knife is placed on the transmission belt. At that time, it is equivalent to completing a mold knife cutting, and the entire equipment is about 3.5 meters long. Compared with the first type of hydraulic machine for stamping and cutting, this kind of die knife cutting has some advantages. The operator will not be injured by stamping. Cutting and forming), based on a large piece or a large area (1.2X0.7m) frame material, the production capacity is about 7 pieces per minute.

But there are also the following problems:

Potential safety hazard: After cutting and forming, the operator will bend over to pick up the cut products with his hands. At this time, the operator's hands will still be injured; at the same time, this kind of equipment has no stroke control when it is in place during the cutting process, and only depends on eye observation. There is no terminal anti-collision protection, and the equipment itself actually has certain security risks. Due to the circular motion of the belt transmission, the equipment does not run in place and has no terminal safety control, so there are certain safety hazards. At the same time, due to the negligence of the operator, the failure to control it in time will cause the mold knife to fall from the machine table and break.

Greater labor intensity: Due to the long length of the equipment, the operator needs to run back and forth to work at both ends, loading and unloading materials back and forth. According to the production capacity of about 7 pieces per minute, the length of the equipment is about 3.5 meters, and the length of the mold knife is 1.2 meters, which is equivalent to 1 piece. 3.5-1.2=2.3 meters, the production capacity is 420 pieces per hour, and the production capacity is 3360 pieces in 8 hours per day, which is equivalent to 7.7KM.

Poor quality stability: Since the mold knife is directly placed on the transmission belt, when it passes through the pressure cutting of the roller, it will be aggravated by the friction of the conveyor belt and the strong rolling friction of the roller, which will aggravate the wear of the bottom of the mold knife, gradually lose parallelism, and lose After the parallelism, the die edge loses the vertical force, the product cutting accuracy will be affected, and the product quality will also be affected, which may eventually cause the die edge to be damaged and cause unnecessary waste.

Low production capacity: Since the operator needs to walk back and forth during work, and also needs to bend down to pick up the cut products, it is very time-consuming and has a great impact on production capacity.

Either way, there are disadvantages such as low production capacity, no safety guarantee for people and equipment, high labor intensity, high energy consumption, shortened life of mold knives, and unguaranteed product qualification rate and quality.
