Detailed description of the preferred embodiments

The invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1, a back sealing powder packaging machine color code bag length adjusting device comprises a first color code sensor 1, an adjusting rod 3, a driving rod 4, a motor 5 and a second color code sensor 2. Referring to fig. 2, the first color code sensor 1 comprises a first probe 11, and the first probe 11 and the first color code sensor 1 are clamped and fixed; a through-hole has been seted up to color mark sensor 1, and adjusting lever 3 passes the through-hole and with color mark sensor 1 sliding connection. The two ends of the adjusting rod 3 are respectively provided with a connecting block 31, the adjusting rod 3 and the two connecting blocks 31 are respectively fixed by bolts, and the central shaft of the adjusting rod 3 is vertical to the largest side surface of the connecting block 31. Each connecting block 31 is connected with one driving rod 4 through threads, and the driving rod 4 is perpendicular to the adjusting rod 3. One end of the driving rod 4 is connected with a motor 5, and the motor 5 and the driving rod 4 are fixed through threads; the motor 5 is fixed on the supporting plate 7. Referring to fig. 3, the second color mark sensor 2 comprises a second probe 21, and the second probe 21 and the second color mark sensor 2 are clamped and fixed; the second color code sensor 2 is provided with a through hole, and the fixing rod 6 penetrates through the through hole and is in sliding connection with the second color code sensor 2; the fixing rod 6 is perpendicular to the support plate 7 and is bolted to the support plate 7.

The first color patch sensor 1 and the second color patch sensor 2 detect the color patch sites on the film by using the reflection and absorption of visible light. Taking the first color mark sensor 1 as an example, the first probe 11 emits a beam of visible light directly, when the visible light irradiates the color mark site of the film, the color mark site reflects the color light corresponding to the color of the first probe and absorbs other color lights, the reflected color light is received by the first probe 11 and converted into an electric signal, after the electric signal is transmitted to a computer, the computer identifies and processes the electric signal and then emits a transverse sealing instruction, and finally, the related structure is controlled to complete transverse sealing.

The first color code sensor 1 and the second color code sensor 2 can independently detect two color code loci. If define the distance between two adjacent color code sites as a complete bag length to adjust the position between a color code sensor 1 and a color code sensor 2, make it align two adjacent color code sites respectively, then a color code sensor 1 and a color code sensor 2 can detect the color code site and send the signal of telecommunication simultaneously. The computer is arranged, the transverse sealing instruction can be sent out only when the computer receives the electric signals of the first color mark sensor 1 and the second color mark sensor 2 at the same time, and the electric signals sent out by the first color mark sensor or the second color mark sensor can not enable the computer to send out the transverse sealing instruction. The advantage of this is that when the first color mark sensor 1 and the second color mark sensor 2 detect the electrical signal from the color mark site twice at the same time, the film moves exactly for a complete bag length, and the interval between the two transverse sealing positions is exactly for a complete bag length. More importantly, the computer can not respond to the electric signals of the single color code sensor, so that the phenomenon that the single color code sensor falsely detects and sends the electric signals and enables the computer to send transverse sealing instructions is avoided, and the generation of short bags is prevented.

The first color patch sensor 1 is movable along the adjustment rod 3, and the first color patch sensor 1 can be correctly aligned with the color patch site when the bag width is changed. The motor 5 drives the driving rod 4, so that the driving rod 4 rotates by taking the center shaft of the driving rod 4 as the center shaft, the connecting block 31 can be driven to move along the driving rod 4, and the first color code sensor 1 can also be correctly aligned with the color code locus when the length of the bag is changed.

Referring to fig. 3, a second focusing nut 22 is installed on the second color mark sensor 2, the second focusing nut 22 is in threaded connection with the second color mark sensor 2, and the focusing nut and the second probe 21 are clamped and fixed.

When the distance between the color mark sensor and the film is far, the visual field range of the probe is larger than that of the actual color mark site, and the probe is interfered by colors except the color mark site to generate false detection, so that the distance between the color mark sensor and the film to be detected needs to be adjusted in actual work, and the colors appearing in the detection range of the color mark sensor are as few as possible. Taking the first color scale sensor 1 as an example, the first focusing nut 12 is rotated, and the first focusing nut 12 drives the first probe 11 to move along the central axis direction of the focusing nut. This has the advantage that the distance between the first probe 11 and the film can be adjusted to make the monitoring range of the first color mark sensor 1 coincide with the color mark site on the film as much as possible, thereby improving the monitoring accuracy of the first color mark sensor 1.

Referring to fig. 2, a first fixing bolt 13 is further mounted on the first color mark sensor 1, the first fixing bolt 13 is perpendicular to the central axis of the first focusing nut 12, and the first fixing bolt 13 is perpendicular to the adjusting rod 3; a fixing bolt 13 and a color mark sensor 1 are in threaded connection, and the tail end of the fixing bolt 13 is abutted against the adjusting rod 3. Referring to fig. 3, a second fixing bolt 23 is installed on the second color mark sensor 2, the second fixing bolt 23 is perpendicular to the central axis of the second focusing nut 22, and the second fixing bolt 23 is perpendicular to the fixing rod 6; no. two gim pegs 23 and No. two color mark sensor 2 threaded connection, No. two gim pegs 23's terminal and dead lever 6 conflict.

Taking the first fixing bolt 13 as an example, the first fixing bolt 13 and the adjusting rod 3 are abutted to generate friction force, so that the movement of the first color mark sensor 1 on the adjusting rod 3 can be avoided, and the fixing effect of the first color mark sensor 1 is realized. The advantage of doing so is, fixed color mark sensor 1 is favorable to maintaining the stability of a probe 11 direction of detection, guarantees that a probe 11 aligns with each color mark locus, avoids can't detect the color mark locus because of a probe 11 skew.

The three film clamping rods 8 are divided into two rows, and the installation sections of the film clamping rods are in a shape like a Chinese character 'pin'. The first probe 11 is opposite to a gap between the two film clamping rods 8 at the bottom of the shape like a Chinese character 'pin'. This has the advantage that the film clamping rod 8 forces the film to pass smoothly, preventing the film from buckling and blocking the color mark sites.

Referring to fig. 1, three film guide rods 9 are further installed between the two support plates 7, the film guide rods 9 are parallel to the fixing rods 6, and the film guide rods 9 and the support plates 7 are fixed through bolts. The sections of the three film guide rods 9 are in a shape like a Chinese character 'pin', and the second probe 21 is over against the gap between the two film guide rods 9 at the bottom of the shape like the Chinese character 'pin'. The advantage of this is that the film guide rod 9 can make the film smooth without the phenomenon of hanging and dragging the floor,

the concave-convex or bending of the surface of the measured object has large influence on the detection of the color mark sensor, and the color mark sensor easily misses the color mark site at the bending part. Therefore, the film is fixed by the clamping rod to keep flat, the stability of the monitoring result of the color mark sensor is guaranteed, and the phenomenon that the transverse sealing position is missed is avoided.
