Description

Technical Field

[0001] The utility model relates to a mould, in particular to a combined switching mould for a packaging machine. Background Art

[0002] Moulds are commonly used in packaging equipment. Current packaging machines generally have a set of moulds. When producing more than two products, the machine needs to be stopped to replace the moulds to meet the vacuum packaging needs of products of different sizes. However, current moulds are generally heavy and it is difficult to fix, disassemble and replace them, which not only reduces packaging efficiency but also is not conducive to cost savings. Utility Model Content

[0003] In order to solve the above problems, the purpose of the utility model is to provide a combined switching mold for a packaging machine.

[0004] To achieve the above-mentioned purpose, the technical solution of the utility model is: a combined switching mold for a packaging machine, including a fixed frame and a horizontal guide rail installed on the fixed frame, and a plurality of molds arranged in sequence are supported on the guide rail by multiple groups of rodless cylinders, and the fixed frame and the guide rail reserve the length of at least one mold.

[0005] Furthermore, the fixing frame is composed of a middle plate and side plates located at both ends of the middle plate, each guide rail is fixed on the middle plate and the side plate respectively, the bottom of the middle plate and the side plate are respectively fixed with bottom plates, and the two ends of each bottom plate are respectively vertically fixed with fixing plates.

[0006] Furthermore, the mold has two pieces, and a plurality of grooves are arranged on the surface of each piece of the mold.

[0007] Furthermore, a positioning block is fixed to the lower surface of each mold, a conical groove is arranged on the lower surface of the positioning block, and a plurality of positioning columns driven to rise and fall by a cylinder are passed through the fixed frame, and the upper end of each positioning column is a cone head that matches the shape of the conical groove.

[0008] Furthermore, buffer baffles are respectively provided at both ends of the fixing frame.

[0009] Furthermore, a plurality of vertical strip-shaped installation holes are respectively opened on the upper end of each fixing plate.

[0010] Through the above settings, since the fixed frame and the guide rail reserve the length of at least one mold, all the molds can be horizontally moved along the guide rail on the fixed frame by the distance of at least one mold, so that it is convenient to realize the switching of molds at different positions. When switching molds, for example, switching the mold of the middle plate, the mold in that part is moved to the part reserved by the fixed frame and the guide rail by the rodless cylinder, and then the molds in other parts are moved to the middle plate by the rodless cylinder, thereby realizing the switching of molds of different models.

[0011] The advantages of the utility model are: the utility model can package at least two products of different sizes, and is convenient for seamless switching of molds, and there is no need to stop the machine when switching molds, which not only saves time and manpower, but is also faster and more efficient, and fully guarantees packaging efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The utility model is now further described with reference to the accompanying drawings.

[0014] Figure 2 It is a three-dimensional structural schematic diagram of the fixing frame of the utility model;

[0015] Figure 3 It is a three-dimensional structural schematic diagram of the mold of the utility model. DETAILED DESCRIPTION

[0016] like Figure 1-3 As shown, a combined switching mold for a packaging machine includes a fixed frame 1 and a horizontal guide rail 2 installed on the fixed frame 1, and a plurality of molds 4 arranged in sequence are supported on the guide rail 2 by a plurality of groups of rodless cylinders 3, and the fixed frame 1 and the guide rail 2 reserve the length of at least one mold 4. For example, there are two molds 4, and a plurality of grooves 5 are respectively arranged on the surface of each mold 4. The grooves 5 of the two molds 4 are different in size and even in shape, so that the packaging of two products can be adapted.

[0017] In order to facilitate the adaptation and installation with the packaging machine frame, the fixed frame 1 is specifically composed of a middle plate 101 and side plates 102 located at both ends of the middle plate 101, each guide rail 2 is fixed on the middle plate 101 and the side plate 102, respectively, and the bottom of the middle plate 101 and the side plate 102 are respectively fixed with a bottom plate 103, and the two ends of each bottom plate 103 are respectively vertically fixed with a fixed plate 104, and the upper end of each fixed plate 104 is respectively opened with a plurality of vertical long strip mounting holes 105.

[0018] In order to better position and limit, a positioning block 6 is fixed on the lower surface of each mold 4, and a conical groove 7 is arranged on the lower surface of the positioning block 6. A plurality of positioning columns 8 driven to rise and fall by a cylinder are passed through the fixed frame 1, and the upper end of each positioning column 8 is a cone head which matches the shape of the conical groove 7. Buffer baffles 9 are arranged at both ends of the fixed frame 1, respectively, and the buffer baffles 9 can prevent the mold 4 from slipping out when it moves to the end.

[0019] The working principle of the utility model is as follows: since the fixed frame 1 and the guide rail 2 reserve the length of at least one mold 4, all the molds 4 can be horizontally moved along the guide rail 2 on the fixed frame 1 by at least one distance of the mold 4, so that it is convenient to realize the switching of the mold 4 at different positions. When switching the mold 4, for example, switching the mold 2 of the middle plate 101, the mold 2 at this position is moved to the position reserved by the fixed frame 1 and the guide rail 2 by the rodless cylinder 3, and then the mold 2 at other positions is moved to the middle plate 101 by the rodless cylinder 3, thereby realizing the switching of molds of different models.

[0020] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
