[0002] The continuous blowing, filling and sealing machine can complete a series of process flows including continuous forming, filling and sealing without cutting the tube blank. The equipment uses a pair of ring chains to carry multiple molds. A single bearing is installed on the mold to withstand the mold closing pressure. Due to the high pressure required for mold closing, the single bearing is subjected to high force, which makes the bearing easily damaged. At the same time, the mold swings up and down when it rotates in the circular direction, resulting in unstable operation. The two sets of molds rub against each other, which affects their service life. Frequent disassembly and assembly of the mold to replace the bearing seriously affects production efficiency.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] Figures 1 to 3An embodiment of a continuous blow-fill-seal integrated machine forming mold device of the present invention is shown. The continuous blow-fill-seal integrated machine forming mold device of this embodiment includes two sets of forming mold assemblies 1. A mold clamping and forming area 2 is formed between the two sets of forming mold assemblies 1. The forming mold assembly 1 includes a mold clamping positioning block 3 and a plurality of forming molds 10 arranged around the mold clamping positioning block 3. A rolling assembly is provided on the forming mold 10. The rolling assembly includes three rolling elements. At least two of the three rolling elements are arranged in the front-to-back direction ( Figure 1 The center is perpendicular to the paper, that is, at least two rolling elements are in different vertical planes), the mold positioning block 3 is provided with three parallel guide surfaces on the side close to the mold forming area 2, and there is a height difference between at least two guide surfaces (see Figure 3 , the upper end of the first guide surface 31 is higher than the upper end of the second guide surface 32), when the molding die 10 moves to the mold closing molding area 2, the three rolling elements are in contact with the three guide surfaces one by one.

[0028] In the forming mold device of the continuous blowing, filling and sealing machine of this embodiment, when the two corresponding left and right forming molds 10 move to the mold closing and molding area 2 for mold closing, the three rolling elements contact the three guide surfaces on the forming mold 10 one by one at the same time, and at least two of the three rolling elements are arranged in the front-to-back direction, and there is a height difference between at least two of the three guide surfaces. This vertically staggered and front-to-back staggered arrangement structure of the rolling elements can reduce the friction between the vertical swing and the forming mold 10 while achieving the distribution of the mold closing pressure, thereby improving the operating stability, extending the service life of the rolling elements, avoiding frequent disassembly and replacement of the mold, and helping to ensure production efficiency.

[0029] As a preferred embodiment, the three rolling elements include a first rolling element 11 and two second rolling elements 12 disposed axially on either side of the first rolling element 11. The axes of the two second rolling elements 12 coincide with each other and are parallel to the axis of the first rolling element 11. The three guide surfaces include a first guide surface 31 and two second guide surfaces 32 disposed on either side of the first guide surface 31. When the first rolling element 11 contacts the first guide surface 31, the two second rolling elements 12 respectively contact the two second guide surfaces 32 in a one-to-one correspondence. The two second rolling elements 12 are disposed on opposite sides of the first rolling element 11, resulting in good force symmetry in the front-to-back direction.

[0030] Furthermore, in this embodiment, when the molding mold 10 moves to the mold closing molding area 2, the height of the second rolling element 12 is less than the height of the first rolling element 11, that is, when the mold is closed, the upper first rolling element 11 shares the mold closing pressure, and the lower two second rolling elements 12 share the mold closing pressure. This triangular arrangement is conducive to ensuring operational stability.

[0031] Furthermore, in this embodiment, the distance between the first guide surface 31 and the mold clamping and molding area 2 is smaller than the distance between the second guide surface 32 and the mold clamping and molding area 2, that is, relative to the second guide surface 32, the first guide surface 31 protrudes toward the mold clamping and molding area 2, so that the first guide surface 31 can provide a limiting effect in the front and rear directions for the second rolling element 12, and the structure is simple and reasonable.

[0032] See Figure 2 and Figure 3 Furthermore, in this embodiment, two groups of rolling assemblies are provided on the forming mold 10, and the two groups of rolling assemblies are arranged at intervals along the axial direction. There are two mold closing positioning blocks 3, and the two mold closing positioning blocks 3 are arranged one-to-one corresponding to the two groups of rolling assemblies, which is conducive to ensuring the force balance at both ends of the forming mold 10.

[0033] As a preferred embodiment, the rolling element is a rolling bearing. Rolling bearings are simple in structure, mature and reliable in technology, and low in cost. Of course, in other embodiments, the rolling element can also be a roller, a ball, etc.

[0034] Example 2

[0035] Figure 4 Another embodiment of the continuous blow-fill-seal machine mold assembly of the present invention is shown. This embodiment is substantially the same as the first embodiment, except that the rolling assembly further comprises two third rolling elements 13 disposed axially on either side of the first rolling element 11. The axes of the third rolling elements 13, the second rolling element 12, and the first rolling element 11 are parallel. The mold clamping and positioning block 3 is also provided with two third guide surfaces (not shown) disposed on either side of the first guide surface 31. When the first rolling element 11 contacts the first guide surface 31, the two third rolling elements 13 contact the two third guide surfaces in a one-to-one correspondence. When the mold 10 moves to the mold clamping and molding area 2, the height of the third rolling elements 13 is less than that of the second rolling elements 12. The provision of two third rolling elements 13 further distributes the mold clamping pressure and increases the number of contact points between the mold 10 and the mold clamping and positioning block 3 in the height direction. This makes it suitable for molds 10 with larger vertical dimensions and can be used to mold longer plastic containers.

[0036] Furthermore, in this embodiment, the distance between the second guide surface 32 and the mold clamping and molding area 2 is smaller than the distance between the third guide surface and the mold clamping and molding area 2, that is, relative to the third guide surface, the second guide surface 32 protrudes toward the mold clamping and molding area 2, so that the second guide surface 32 can provide a limiting effect in the front and rear directions for the third rolling element 13, and the structure is simple and reasonable.

[0037] Furthermore, in this embodiment, the axes of the two third rolling elements 13 coincide with each other. The two third rolling elements 13 are arranged oppositely on both sides of the first rolling element 11, and the force symmetry in the front-to-back direction is good.

[0038] Example 3

[0039] Figure 5 Another embodiment of the forming mold device of a continuous blowing, filling and sealing machine of the present invention is shown. The forming mold device of the continuous blowing, filling and sealing machine of this embodiment is basically the same as that of the first and second embodiments, except that: in this embodiment, the forming mold 10 is provided with four groups of rolling assemblies, which are arranged at intervals along the axial direction. Accordingly, four mold closing positioning blocks 3 are provided, and the four mold closing positioning blocks 3 are arranged in a one-to-one correspondence with the four groups of rolling assemblies. This is suitable for forming molds 10 with larger dimensions in the front-to-back direction, and can form multiple plastic containers at the same time, which is conducive to improving production efficiency.
