Description

Technical Field

[0001] The invention relates to the technical field of forming pulp molded integral cylindrical bottle products, in particular to a compacting mechanism with radial contraction function during the forming process of the pulp molded integral cylindrical bottle. Background Art

[0002] While plastics bring many conveniences to humans, they also bring a great burden to the ecological environment. Plastic products have the disadvantages of being difficult to collect, recycle, and dispose of, and have a long period of environmental damage, which has caused great damage to the ecological environment. People have a huge demand for bottle packaging products, so promoting the use of environmentally friendly materials to make packaging bottle products to gradually replace plastic bottle packaging products is of great significance to environmental protection.

[0003] Pulp molding, as a three-dimensional papermaking technology, is an important technology for the production of green packaging paper products. It can usually use waste paper or bamboo fiber and sugarcane fiber as raw materials to produce paper products of a certain shape. The raw materials of pulp molding are widely available and pollution-free. Its finished products are widely used in many aspects of production and life such as food packaging, industrial product cushioning packaging, agricultural seedling cultivation, medical consumables, etc. It is of great significance to promote paper-plastic bottles instead of plastic bottles and promote the development of paper-plastic bottle production technology.

[0004] According to the survey, the existing traditional solutions at home and abroad mainly include the following: Patent CN201320746431 involves a paper-plastic bottle body, including a bottle body and a plastic end cap arranged on the upper part of the bottle body, the bottle body is an upwardly open paper tube, and the lower edge of the plastic end cap is tightly connected with the opening of the paper tube to close the inner cavity of the paper tube. The above-mentioned paper-plastic bottle has a complex structure, high cost, and contains plastic materials, resulting in poor environmental protection; Patent CN 111593616A discloses an extrusion mold and extrusion process for a paper-plastic integral bottle, which applies high temperature and high pressure resistant elastomer materials to the design of the paper-plastic mold. This molding method of using elastomer materials to extrude the inner cavity of the paper-plastic bottle body has extremely high requirements for the pressure and high temperature resistance of the elastomer materials, and the elastic materials are repeatedly heated and pressurized and deformed during mass production, and their service life is short and the reliability is poor.

[0005] Columnar bottles are widely used in the packaging field. In the process of promoting paper-plastic columnar bottles to replace plastic columnar bottles, improving the structural strength of paper-plastic columnar bottles is of great significance for the promotion and use of paper-plastic bottles. Therefore, the present invention also designs a paper-plastic integral columnar bottle compacting mechanism. Summary of the invention

[0006] In view of the deficiencies in the current prior art, the technical problem to be solved by the present invention is to provide a mechanism for compacting the bottom and body of a paper-plastic integral cylindrical bottle during the molding stage, so as to increase the density of paper fibers in the bottom and body of the paper-plastic integral cylindrical bottle, thereby increasing the structural strength of the bottle.

[0007] The purpose of the present invention is achieved through the following technical solutions:

[0008] A paper-plastic integral cylindrical bottle compacting mechanism with radial telescopic function, which is composed of a bottle body pressing plate driving mechanism, a bottle bottom pressing plate driving mechanism, a bottle body pressing plate, and a bottle bottom pressing plate.

[0009] The bottle body pressing plate driving mechanism is composed of a central shaft, a sliding sleeve, a hinge seat C, a connecting rod A, a connecting rod B, and a connecting rod G. The sliding sleeve is sleeved on the central shaft, and the sliding sleeve slides relative to the central shaft. Four hinge seats C are arranged at equal intervals in the peripheral direction of the lower end of the sliding sleeve. The other ends of the four hinge seats C are respectively hinged to four identical connecting rods A, and the other ends of the connecting rods A are respectively hinged to the connecting rods B.

[0010] On the shaft extending from the lower end of the sliding sleeve of the central shaft, three groups of hinge seats C are axially fixedly connected, and the other end of each group of hinge seats C is hinged to four identical connecting rods B, four identical connecting rods G, and four identical bottle bottom pressure plates in sequence;

[0011] The bottle bottom pressing plate driving mechanism is composed of a connecting rod E, a central connecting rod, a bottle bottom driving rod, and a hinge seat D. One end of the connecting rod E is hinged to the central connecting rod through the hinge seat D fixedly connected to the bottle body pressing plate. The lower part of the central connecting rod is hinged to the bottle bottom driving connecting rod. The other end of the bottle bottom driving connecting rod is hinged to the bottle bottom pressing plate.

[0012] The inner side of the bottle body pressing plate is also fixedly connected with two identical hinge seats C, and the other ends of the hinge seats C are hinged to the connecting rod B and the connecting rod G respectively.

[0013] The central axis is driven by a cylinder or a mechanical arm to complete the rotation and vertical movement of the mechanism.

[0014] The sliding sleeve is pushed by a cylinder or a mechanical arm to complete the radial contraction and expansion of the mechanism.

[0015] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0016] The mechanism of the present invention can be driven by a cylinder or a mechanical arm in a contracted state to enter the inner cavity of the paper-plastic cylindrical bottle from the bottle mouth, and then the mechanism can be rotated under the drive of the cylinder or the mechanical arm, and the pressure plate at the bottom of the bottle body and the bottom of the bottle body can be squeezed and contacted to fully compact the bottom of the cylindrical bottle and the bottle body, thereby improving the density of the overall bottom of the paper-plastic cylindrical bottle and the paper fibers of the bottle body, thereby improving the structural strength of the bottle body, and at the same time squeezing out excess water, saving energy consumption in the subsequent drying process, which has great significance and practical value.

[0028] The present invention provides a paper-plastic integral cylindrical bottle compacting mechanism with a radial contraction function. During the process of forming the paper-plastic integral cylindrical bottle, the compacting mechanism can penetrate into the bottle cavity from the bottle mouth. The mechanism is unfolded in the bottle cavity and squeezes the inner cavity of the bottle body and the bottle bottom at the same time, thereby improving the density of paper fibers of the bottle body and the bottle bottom, thereby improving the structural strength of the paper-plastic integral bottle.

[0029] The present invention is described in detail below with reference to the accompanying drawings and embodiments:

[0030] like Figures 1 to 6As shown, the present invention comprises: a bottle body pressure plate driving mechanism, a bottle bottom pressure plate driving mechanism, a bottle body pressure plate 6, and a bottle bottom pressure plate 11. The sliding sleeve 2 is sleeved on the central axis 1, and the sliding sleeve 2 can slide relative to the central axis 1. The lower end of the sliding sleeve 2 is fixedly connected to four hinge seats C3 evenly distributed in the circumferential direction. The four hinge seats C3 are respectively hinged to four identical connecting rods A4, and the other end of the connecting rod A4 is hinged to the connecting rod B5. The central axis 1 is axially fixedly connected to three groups of hinge seats C3. The three groups of hinge seats C3 fixed on the central axis 1 are respectively hinged to four identical connecting rods B5, four identical connecting rods G7, and four identical bottle bottom pressure plates 11. Two identical hinge seats C3 are fixedly connected to the inner side of the bottle body pressure plate 6. The two hinge seats C3 fixed to the inner side of the bottle body pressure plate are respectively hinged to the connecting rod B5 and the connecting rod G7. Therefore, when the sliding sleeve 2 slides relative to the central axis 1 driven by the cylinder or the mechanical arm, the bottle body pressing plate 6 can realize radial contraction and expansion movement. Four hinge seats D12 are fixedly connected to the inner side of the bottle body pressing plate 6. The hinge seat D12 fixed to the bottle body pressing plate 6 is hinged to the connecting rod E8. The other end of the connecting rod E8 is hinged to the central connecting rod 9. The bottom of the central connecting rod 9 is hinged to the bottle bottom driving connecting rod 10. The other end of the bottle bottom driving connecting rod 10 is hinged to the bottle bottom pressing plate 11. Therefore, when the sliding sleeve 2 slides relative to the central axis 1 and drives the bottle body pressing plate 6 to radially contract and expand through the connecting rods A4, B5, and G7, the circumferentially adjacent bottle body pressing plates 6 drive the bottle bottom pressing plates 11 to realize radial contraction and expansion movement synchronously with the bottle body pressing plate 6 through the connecting rods E8, the central connecting rod 9, and the bottle bottom driving connecting rod 10. Therefore, when the sliding sleeve 2 and the central shaft 1 slide relative to each other, the bottle body pressing plate 6 and the bottle bottom pressing plate 11 are opened at the same time, and contact and squeeze the bottle body and the bottle bottom at the same time.

[0031] like Figure 7-8 As shown, when the mechanism is in a contracted state, the cylinder or the mechanical arm drives the mechanism in the contracted state to move vertically from the bottle mouth of the paper-plastic integral cylindrical bottle into the bottle cavity, and then the cylinder or the mechanical arm pushes away the sliding sleeve 2 to slide relative to the central axis 1, so that the mechanism extends, and the bottle body pressing plate 6 and the bottle bottom pressing plate 11 simultaneously contact the bottle body and the inner wall of the bottom of the paper-plastic integral cylindrical bottle. Driven by the rotating cylinder or the mechanical arm, the mechanism rotates, and the bottle body and the bottle bottom pressing plates fully contact and squeeze the bottle body and the inner wall of the bottom of the paper-plastic bottle, thereby improving the density of the paper fibers of the bottle body and the bottom of the paper-plastic integral cylindrical bottle, thereby improving the structural strength of the paper-plastic integral cylindrical bottle.
