ABOUT

The invention relates to the woodworking industry, primarily to the manufacture of ice cream sticks. A device for cutting veneer is known, including a movable table with a feeding unit, a working member in the form of a movable frame with a knotter and a drive 1. However, the knife of the device cuts a pack of H1pone into rectangular strips. In order to carry out the subsequent shaping of the end surfaces of the veneer strips, by knotting ice cream sticks, at KOTopt) ix, the ends are rounded along the radius, it is necessary to organize their assembly and placement in a special additional machine, which is associated with the presence of special equipment and well-known labor costs. also a device for cutting products from a strip material, including a frame, a feeder, a working body, a die and a drive 2. A disadvantage of the known device is that the technological process Ani profile rods for morozhenoIo occurs in two stages; First, the rectangular profile strip is cut, then the ends are rounded. For this, an additional unit for forming an end profile with an additional knife drive is introduced into the device, which in ne: ioM considerably complicates the design. In addition, for the used device, a procurement section is required, whereby veneer sheets are preliminarily sized to fit the dimensions of the table. There is also the need to use raw material for high-quality logging. The purpose of the invention is to simplify the design and expand the technological capabilities of the device. This goal is achieved by the fact that in a device for cutting products from strip material, including a frame, a feed mechanism, a working body, a matrix and a drive, the working body is made in the form of a rotor fixed to the shaft with cutting-out knives, the feed mechanism is fixed a rubber roller shaft, the roller shaft being connected to the rotor shaft by a friction clutch, and the die is placed between the rotor and the feed mechanism, which is mounted to move in a vertical plane. The drawing shows a device for cutting products from a strip material, a general view. The device drives the electric motor 1, which, through tsish 2, the V-belt transmission and the pulley 3, which is also a flywheel, rotates the rotor 4, the shaft of which is fixed in two ball bearings 5. On the rotor 4 there are two carving knives 6, whose profile corresponds to the shape of the product ( ice cream stick). The C-profile 7 matrix is installed on the plate 8, through which the strip 9 is fed. The side rulers 10 and the peak 11 also serve to guide the strip. Automatic feeding. veneer strips are carried out through a friction clutch feed mechanism. The feed mechanism is made in the form of rubber rollers 12 mounted on the shaft 13, rotating in bearings 14, the shells of which are reinforced so that they can be moved in a vertical plane. The feed mechanism is driven by a pulley 15 fastened to the rotor shaft 4, an intermediate tensioning pulley 16, the axis of which is fixed in the spindle 17, an idler pulley 18, which is loosely fastened on the shaft of the feed mechanism and is the drive disk of the friction clutch. One driven disk 19 is rigidly fixed on the shaft, and the second disk 20 is axially displaceable. Felt disks 21 are reinforced between the drive and the driven disks. The clutch disks are pressed by the spring 22, the force of which is regulated by the handwheel 23. The spring 22 is adjusted so that when the front edge of the veneer strip is pressed into the generator of the rotor 4, the slip clutch slips until it is product 24 was cut down. Since the feed rate for each cutting knife (i.e., for every half-turn of the rotor) is provided somewhat more than is required (i.e., more than the width of the cutting stick. my stick), the edge of the veneer strip rests on qilin The drift of the rotor is earlier than the next carving knife is suitable. Due to this, constant contact (clamping) of the billet is ensured with the cylindrical rotor generatrix, which is the final stop determining the width of the Erupted product. In addition, the slipping of the friction clutch after the edge of the workpiece reaches the stop, prevents deformation (formation of folds, creases) of the strip of the spike, as well as the breakdown of the feeding means. The guiding means also serve to prevent deformation, wrinkles, and jamming of the strip of the spindle when the front edge of the guide stops in the rotor cylinder until it slips. The formation of wrinkles, waviness, corrugations, "accordions", prevents the set minimum clearance between the visor 11 and the plate 8. All components and mechanisms of the device are mounted on a common frame 25. The device operates as follows.

The end of the veneer strip is manually inserted into the guide means (tucked under the rubber feed rollers 12). When the motor 1 is turned on through a V-belt transmission, the rotation is transmitted to the rotor 4 with the cutting-out knives 6 as well as the feeding means. The spike strip 9 is picked up by the feed rollers 12 and fed over the plate 8 until its front edge abuts against the end stop, which determines the size of the cut of the cut product - into the cylindrical forming rotor 4. At the same time, the friction clutch is adjusted to transfer a certain force this time, the rubber feed rollers begin to slip, at the same time ensuring tight clamping of the front edge of the spike strip with the rotating rotor cylinder until the cutting-out knife and the tube of the product 24. Approach. feeding each knife cuts out (or at every half turn of the rotor) several) Large Live Schirin felled coli (1/6 Schirin part), i.e. Since the workpiece is pressed against the end stop earlier than the next cutting knife fits and is fixed in this position by the force of the feed rollers, this ensures a stable width of the product being cut.

After the knife approaches and the punching of article 24, which falls down under its own weight, the cycle repeats, i.e. Again, the cut-off product is fed to the width (up to the stop into the rotor cylinder). The repeatability of feed cycles (number of cycles) per rotor revolution depends on the number of cutting knives installed on it. In this case, waste is generated only along the edges of the workpiece in the form of narrow strips with teeth, i.e. reduced to a minimum.

The proposed device for cutting products from a strip material is characterized by simplicity of design, makes it possible to use waste of a spike without limiting its dimensions in length and thickness, and has high productivity and quality.
