Description of the invention

The utility model relates to methods of manufacturing a continuous clip tape made of 2 aluminum and aluminum alloys for use in the food industry, namely in the meat and dairy industry for clips when clamping or fixing the end edges of a sleeve or other packaging material.

Known from the field of technology are "Method of rolling metal tape" | KO patent 2134621, B21801/22, B21837/22, 505813/02, 511C11/54 dated 20.08.1999), "Method of making flattened tape" | KO patent 2100108, B21801/40 dated 12.27.1997), "Method of obtaining a thin metal strip and a rolling mill for its implementation (options)" 70 IKO patent 2146972, B21801/22, B21C47/18 dated 03.27.2000). The analysis of the technical properties of analogs and prototypes based on their characteristics shows that obtaining the expected technical result when using these technical solutions is hindered by some complexity of the production methods and low manufacturability.

The useful model is based on the task of improving the method of manufacturing clips from aluminum and aluminum alloys through the following operations: rolling round aluminum or aluminum alloys 12 wire, obtaining a rectangular tape, applying a profile pattern on it, which increases the adhesion of the clip with the packaging shell, forming a continuous clip tape on the stamp, which ensures an increase in the quality, reliability and tightness of pressing when using a continuous clip tape during portion packing in a sleeve packaging shell of meat and dairy food products.

To implement the proposed utility model, a continuous clip tape production line (hereinafter the line) is used for the production of various standard sizes of continuous aluminum clip tapes used in automatic clippers in food processing industries.

T" method according to the proposed useful model. The line (Fig. 1) consists of an unwinding device 1 for placing a round wire bay, a rolling device for obtaining a strip of rectangular cross-section from a round wire, a crank press b for placing replaceable stamps 7 on it, a winding device 9 29 of the finished clip tape on plastic coils and two racks 8 with non-contact sensors of the automation system placed on them. The control board is fixed on the frame of the winding device. External power supply and internal line separation is carried out through the control panel.

Fig. 2 shows a schematic view of part of the line according to Fig. 1, which allows to implement the method according to the proposed useful model, namely the rolling installation. The rolling plant 17 consists of 60 electric drive 12 with a reducer 13, an intermediate shaft 14 with sprockets 15, a correct device 2 (Fig. 1), a block

From the first group of flattening shafts and block 4 of the second group of shafts, intended for application to the tape obtained after flattening, a profile pattern that increases the adhesion of the staples to the shell.

Fig. 4 schematically presents the general side view of the device in an enlarged form, which is manufactured using the proposed useful model, where T/H-B x5 is the standard size of the clip, T is the pitch of the clip, H is the height of the clip, B is the width of the clip, 5 clip thickness.

The method of implementation of the proposed useful model. Install a coil of wire of the required diameter on the unwinding device 1 (Fig. 1). Insert the straightened end of the wire through the correct device 2 and then through the guide tubes 24 (Fig. 2) of the rolling device 17.

The thickness of the strip coming out of the rolling mill is regulated by changing the gap between the flattening shafts From the first group with the help of adjusting gears 22, made together with thrust screws 29, which move the bearing housings 26 /sliders/ of the upper flattening shaft 18. When the pressure of thrust screws 29 is weakened - sliders under the action of mounted springs 27 move up and the gap between the flattening shafts increases, and due to this, the thickness of the pumped tape increases. When the 7/0 thrust screws are wrapped, the gap between the flattening shafts is reduced and, accordingly, the thickness of the belt being pumped is reduced.

The width of the tape is adjusted by moving the movable rollers 28 (Fig. 2) of the correct device with the stop screws 29. When the movable and fixed rollers 23 of the correct device converge, the resistance to the passage of the wire increases and, as a result, the width of the tape decreases, and when the stop screws are loosened, the gap between /5 rollers increases, the resistance of the passage of the wire decreases and the width of the tape increases. After obtaining the required width of the tape, it is necessary to align the axes of the movable rollers with the help of locking bolts.

Next, the obtained tape passes through the second group of shafts 4 of the rolling unit 17 - the rolling one, which serves to apply the profile pattern 31 (Fig. 4), in the form of grooves, to the formed tape 30 to increase adhesion with the shell of the clipped product.

Next, the prepared tape is formed into a clip tape 30 with the help of a die space. Fig. 3 shows a structural and structural diagram of a part of the line according to Fig. 1, namely the lower plate of the die. To do this, the matrix 47 is installed on the lower plate of the stamp 7 (Fig. 3) so that the holes for the peelers 38 (Fig. 5) in the matrix approximately coincide in the centers with the threaded holes of the plate. The matrix is fixed on the plate with the rear clamp 32 (Fig. 3), and then the front clamp 33 is installed. The front 34 and the rear OZ guides are installed in the groove. The guide device Zb is fixed on the front end of the plate, and the transfer device 37 is installed on the back end. De-stickers 38 are inserted into the matrix through the threaded holes in the plate, and then the bushings 39 of the springs 40 (Fig. 5) of the de-stickers 38 are wrapped, the plungers of the de-stickers are inserted into the bushings, springs and threaded plugs 41 are wrapped. Separators 43 are put on the columns of the lower plate. Strikers 46 are installed on the lower plate of the body 45 close to the matrix.
