[0024] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0025] This device is mainly used in the vertical bag making and packaging process of liquid and fluid materials. It cooperates with the longitudinal sealing mechanism and the film traction mechanism to assist in forming a tubular space, and after the transverse sealing mechanism operates to form the end seal, the material is transported into the semi-open cavity.

[0026] According to the present invention, an auxiliary molding bag making and diverting injection device is provided, comprising: a flying flow pipe 1, a mounting fixed plate 2, an auxiliary bag making diverting injection pipe 3, a film guide fork 4 and an auxiliary molding body 5;

[0027] The flying flow pipe 1 transitions from a large diameter to a preset number of small diameter pipes; the large diameter and small diameter are located at both ends of the auxiliary molding bag making and diversion injection device, the large diameter is connected to the mounting fixing plate 2, and the small diameter is connected to the auxiliary molding body 5;

[0028] The mounting fixing plate 2 is connected to the auxiliary bag making diverter injection tube 3; the auxiliary bag making diverter injection tube 3 is connected to the auxiliary molding body 5; there are two film guiding forks 3, and the film guiding forks 3 are connected to the auxiliary bag making diverter injection tube 3 and the auxiliary molding body 5; they are respectively located on the sides of the auxiliary bag making diverter injection tube 3 and the auxiliary molding body 5; and are usually made of 304 and / or 316 materials.

[0029] Specifically, the flying flow material pipe (1) has three small diameters, and the flying flow material pipe (1) transitions from one large diameter pipe to three small diameter pipes.

[0030] Specifically, the outlet pipe (1) is provided with a clamp joint at its port, which is convenient for installation and replacement.

[0031] Specifically, the first end portion 6 and the second end portion 8 of the film guiding fork 3 are bent toward the auxiliary bag making diversion injection pipe direction 3 , and the bent portion plays a guiding role.

[0032] Specifically, the cross-sectional circumference of the first end portion 6 of the film guiding fork 3 is smaller than the tubular channel formed by heat-sealing into a longitudinal seal.

[0033] Specifically, the cross-sectional circumference of the second end portion 8 of the film guiding fork 3 is smaller than the tubular channel formed by heat-sealing into a longitudinal seal.

[0034] Specifically, the cross-sectional perimeter of the connection point 7 between the auxiliary bag-making diversion injection tube 3 and the auxiliary forming body 5 is equal to the tubular channel formed by heat-sealing into a longitudinal seal.

[0035] Specifically, the auxiliary molding body 5 is made of an embossed plate with a rice grain pattern to reduce friction resistance during the auxiliary bag-making process.

[0036] Specifically, there are three discharge pipes 6 ; the actual cross-sectional area of ​​the feed pipe 1 is equal to the sum of the cross-sectional areas of the three discharge pipes 6 .

[0037] Specifically, the auxiliary forming body 5 gradually increases in width from the large diameter direction to the small diameter direction, and narrows obliquely from the connection point 7 toward the central axis.

[0038] The present invention is a structurally symmetrical auxiliary forming bag-making and diverting injection device.

[0039] The present invention is further described by the following preferred examples:

[0040] After being properly installed and fixed, the device is actually placed in the collar channel and interlaced with it. After the packaging film is guided by the collar former, it wraps the device inside. After being folded in half, the part that exceeds the theoretical inner circumference of the collar former is heat-sealed into a longitudinal seal after passing through the longitudinal sealing mechanism, thus forming a tubular channel (internal circumference L of the cross section). Figure 3 In the figure, when passing through section A, La is slightly smaller than L, and the formed tubular channel can pass smoothly. After being guided by the gradual film guide fork, it naturally transitions to section B, where Lb = L. After passing section B, the auxiliary molding body begins to narrow inward, and the tubular channel continues to expand to both sides along the guidance of the film guide fork. The abdomen narrows along the auxiliary molding body until it reaches section C, where Lc is also slightly smaller than L. After leaving the film guide fork, the two sides of the tubular channel are folded in half to become flat and guided into two pairs of traction pressure wheels. During the pressing and rotation of the traction wheels, the film is pulled under the action of static friction. Figure 3 During the whole process, the theoretical envelope line fits at most the fillet formed by the bending of the auxiliary molding body and the outer circle of the film guide fork. There is still a small distance between the actual film and the auxiliary molding body, so there is no large-area fitting contact. In addition, the auxiliary molding body is made of an embossed plate with a rice grain pattern to minimize the contact area between the film and it, thereby reducing the friction resistance in the auxiliary bag-making process and avoiding the deviation of the film to the greatest extent. For liquid materials with poor fluidity and high target gram weight, the bottleneck of packaging efficiency lies in the filling speed. Since the diversion injection of this device does not significantly reduce the flow cross-sectional area, it is significantly better than the 1-to-1 variable diameter injection method of similar traction methods, greatly improving packaging efficiency.
