Description

Technical Field

[0001] The present application relates to the field of bottle preform transportation, and in particular to a bottle preform transport device. Background Art

[0002] Preforms are the raw materials for producing plastic bottles. In the automated or semi-automated production lines of plastic bottles, various mechanical devices are needed to carry the preforms and transport them to the processing points of the bottle blowing process. At present, the preforms are generally clamped one-to-one by a clamping device, and the clamping device is transferred by a track drive device. This method of transporting preforms requires the preforms to be coordinated with the clamping device in turn, and requires a large number of clamping devices, which is expensive. In addition, the distance between adjacent clamping mechanisms is large, and a certain length of track can carry fewer preforms. Utility Model Content

[0003] In order to solve the above-mentioned defects of the related prior art, the present application provides a bottle preform transporting device, which does not need to use a clamping device to clamp the bottle preform one-to-one, can carry more bottle preforms at the same time, and has strong practicality.

[0004] In order to achieve the above purpose, the utility model adopts the following technologies:

[0005] A preform carrier device, comprising:

[0006] The first transmission mechanism is provided with two groups at intervals, each comprising two first rotating heads rotating around their own central axes and first rotating belts sleeved thereon, the upper surfaces of the two first rotating belts being arranged in the same plane and the straight sections thereof being arranged in parallel;

[0008] Furthermore, a first support plate is provided between the first rotating heads of the same group, and an edge of the first support plate is in contact with the first rotating belt. A second support plate is provided between the second rotating heads of the same group, and an edge of the second support plate is in contact with the second rotating belt.

[0010] Furthermore, a load-bearing track and a linear mechanism are connected to the lower surface of the first mounting plate.

The driving shaft of the linear mechanism is connected to the slide bar. The slide bar is vertically connected to a third connecting column. The third connecting column is vertically connected to the upper surface of the second support plate.

[0011] The beneficial effects of the utility model are:

[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0017] like Figure 1 As shown, this embodiment provides a preform transporting device, comprising a first conveying mechanism 1 and a second conveying mechanism 2.

[0020] During operation, when the second conveying mechanism 2 is arranged directly below the first conveying mechanism 1, the device is used to convey the preform to the processing point of the bottle blowing process. At this time, the preform successively enters between two opposite straight sections of the two first conveying belts 12 from one end of the first conveying mechanism 1. When the preform is conveyed to the other end of the first conveying mechanism 1 and leaves the first conveying mechanism 1, the preform falls between two opposite straight sections of the two second conveying belts 12 at one end of the second conveying mechanism 2. When the preform is conveyed to the other end of the second conveying mechanism 2, the second conveying mechanism 2 is moved so that the second conveying mechanism 2 is located directly above the bottle blowing mold and its clamping mechanism. The second conveying belt 12 continues to drive the preform to move until the preform leaves the other end of the second conveying mechanism 2 and falls into the clamping mechanism. At this time, the bottle blowing process can be carried out.

[0022] Preferably, Figure 2 As shown, the lower surface of the first support plate 13 is vertically connected to the first connecting column 31, and the first connecting column 31 is vertically connected to the first mounting plate 32. The first mounting plate 32 is vertically rotatably connected to two second connecting columns 33, and the second connecting columns 33 are coaxially connected to the first rotating head 11 respectively. A first rotating mechanism 34 is provided on the first mounting plate 32. The first rotating mechanism 34 can adopt a rotating motor, a rotating cylinder or other rotating driving mechanical device; the driving shaft of the first rotating mechanism 34 is coaxially connected to one of the second connecting columns 33, so as to drive one of the second connecting columns 33 to rotate The lower surface of the second support plate 23 is vertically connected with a fourth connecting column 36, the fourth connecting column 36 is vertically connected with a second mounting plate 37, the second mounting plate 37 is vertically rotatably connected with two fifth connecting columns 38, the fifth connecting columns 38 are coaxially connected to the corresponding second rotating heads 21, and a second rotating mechanism 39 is provided on the second mounting plate 37. The second rotating mechanism 39 can adopt a rotating motor, a rotating cylinder or other rotating driving mechanical device; the driving shaft of the second rotating mechanism 39 is coaxially connected to one of the fifth connecting columns 38, and is used to drive one of the fifth connecting columns 38 to rotate.

[0023] Preferably, Figure 2 As shown, the lower surface of the first mounting plate 32 is connected with a load-bearing rail 14 and a linear mechanism 16. In this example, the linear mechanism 16 adopts a linear cylinder; the load-bearing rail 14 and the linear mechanism 16 are both arranged along the straight section direction of the first rotating belt 12, and a slide bar 15 is slidably fitted in the load-bearing rail 14.
