The handle 2431 is used for overcoming the pulling force of the second stretching spring 2429 through manual application of external force, so that the first clamping wheel 2423 and the second clamping wheel 2424 are in a separated state, and the packaging film is conveniently installed at a position between the first clamping wheel 2423 and the second clamping wheel 2424.

Specifically, a second connecting arm 2432 is fixed between the first mounting seat 2421 and the first mounting plate 2410, the second connecting arm 2432 is rotatably connected with a third rotating shaft 2433, the third rotating shaft 2433 is disposed at one end of the first mounting seat 2421 and is in transmission connection with the first rotating shaft 2426 through a bevel gear, and the third rotating shaft 2433 is disposed at one end of the first mounting plate 2410 and is in transmission connection with the first driving component 2425. Through the arrangement of the third rotating shaft 2433 and the bevel gears mounted on the first rotating shaft 2426 and the third rotating shaft 2433, the bevel gear on the first rotating shaft 2426 is in meshed connection with the bevel gear on the third rotating shaft 2433, so that the first rotating shaft 2426 is in transmission connection with the first driving assembly 2425.

Preferably, the second connecting arm 2432 is sleeve-shaped, and the third rotating shaft 2433 passes through a center hole of the second connecting arm 2432, so that the third rotating shaft 2433 is placed inside the second connecting arm 2432 and can rotate along an axis of the second connecting arm 2432, and further the structure is more compact, and the third rotating shaft 2433 is convenient to mount.

Referring to fig. 2, in the above description, the first driving assembly 2425 and the driving motor of the second transferring assembly 2600 are the same driving assembly, that is, one driving motor drives the second transferring assembly 2600 to move and the first clamping wheel 2423 to rotate at the same time, in practical applications, the motor can also be in transmission connection with the guiding roller 2330, so that the guiding roller 2330 also has a driving force.

and S100, clamping both sides of the packaging film between the first clamping wheel 2423 and the second clamping wheel 2424 of the first pressing structure 2400 and between the two heating sheets 2443 of the first pressing structure 2400, so that the first clamping wheel 2423 and the second clamping wheel 2424 of the first pressing structure 2400 can drive the packaging film to move, and the packaging film is conveyed and passes through the positions of the two heating sheets 2443.

And S200, starting the first conveying assembly 1000 and the packaging device 2000, and synchronizing the conveying of the section fittings by the first conveying assembly 1000 and the conveying of the packaging films by the packaging device 2000. The control member 2200 starts counting the number of profile parts and reading the distance between two adjacent profile parts according to the signal of the second detector 1200, while the control member 2200 starts counting the number of profile parts according to the signal detected by the first detector 1100. In this step, the section fittings are required to be placed on the first conveying assembly 1000, then the first conveying assembly 1000 is conveyed to the packaging film, then the packaging film passes through the first pressing structure 2400 and the second pressing structure 2500, the packaging film is subjected to hot pressing to form a packaging bag, and the section fittings are placed in the packaging bag.

In the process of conveying the profile fittings on the first conveying assembly 1000, the profile fittings sequentially pass through the positions of the second detector 1200 and the first detector 1100 and are detected by the second detector 1200 and the first detector 1100, the profile fittings detected by the second detector 1200 and the first detector 1100 generate corresponding signals, and the control assembly 2200 can calculate the actual distance value between two adjacent profile fittings according to the signals of the second detector 1200 and the first detector 1100 and the conveying speed of the first conveying assembly 1000 and judge the difference value between the actual distance value and the set distance.

When the second detector 1200 detects that the distance between two adjacent profile assemblies is not equal to the set distance, the control component 2200 records and calculates the time T of the fast transfer or the slow transfer to be performed, wherein the fast transfer is performed when the distance between two adjacent profile assemblies is greater than the set distance, and the slow transfer is performed when the distance between two adjacent profile assemblies is less than the set distance.

In the above, before the first transferring assembly 1000 and the packing device 2000 are started, the speed values of the fast transferring, the slow transferring and the normal transferring of the first transferring assembly 1000 are set, and the transferring speed of the packing device 2000 is equal to the normal transferring speed of the first transferring assembly 1000.

S400, after the first detector 1100 detects that the previous one of the two profile fittings with unequal distances passes, the control component 2200 controls the first transferring component 1000 to transfer fast or slowly, and the operation time is the time T calculated in step S300, and then the first transferring component 1000 resumes the normal speed operation. After the previous section fitting enters the packaging device 2000, the packaging device 2000 is installed for normal speed transmission, and the transmission speed of the first transmission assembly 1000 is controlled to enable the transmission speed of the previous section fitting to be unequal to that of the next section fitting, so that the effect of adjusting the distance between the previous section fitting and the next section fitting is achieved, the distance between the section fittings entering the packaging device 2000 is enabled to be equal, therefore, the lengths of packaging films of the packaging section fittings can be guaranteed to be equal, the packaging device 2000 performs uniform hot pressing on the packaging films, and local overheating is avoided.

In the above, the control component 2200 may give the corresponding serial number to the corresponding profile fitting according to the signals that the first detector 1100 and the second detector 1200 detect the profile fitting, so that the positions of two profile fittings requiring the distance adjustment may be known. For example, in step S300, the second detector 1200 detects that the distance between the nth and (N + 1) th profile accessories needs to be adjusted, and in step S400, after the first detector 1100 detects that the nth profile accessory passes through, the first conveying assembly 1000 is controlled to perform corresponding actions, so as to adjust the distance between the nth and (N + 1) th profile accessories.
