Description

Technical Field

[0001] This invention relates to the field of silkworm cocoon processing technology, specifically an automatic silkworm cocoon peeling and stripping system. Background Technology

[0002] Sericulture is a traditional and advantageous industry in my country, with silkworm cocoon production accounting for more than three-quarters of the world's total. A silkworm cocoon refers to the cocoon of a mulberry silkworm. It is the protective, sac-like layer of the silkworm's pupa, containing the pupa. The cocoon layer can be reeled into silk, and the cocoon shell and waste silk after reeling can be used as raw materials for silk floss and spun silk. Common silkworm cocoons are oblong, oval-waisted, spherical, or spindle-shaped, or slightly constricted in the middle. During silkworm breeding, the pupa needs to be separated from the cocoon without damaging it. The common method is for farmers to manually cut the cocoon shell, but this is difficult to control the size of the cut, easily injuring the pupa inside. Mechanical cutting devices typically only place the cocoon into the clamping area and make the cut at the top. This method, to avoid cutting the inner pupa, generally avoids making the cut too deep, which could make it difficult for the pupa to separate from the cocoon later.

[0003] This case arose in order to resolve the aforementioned issues. Summary of the Invention

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the present application more clear and explicit, the present application is further described in detail below in combination with specific embodiments and with reference to the drawings.

[0026] Referring to the drawings, an automatic cocoon shell cutting and peeling system comprises a frame 1, a conventional conveying mechanism is formed on one side of the frame 1, a conventional cocoon guide-in mechanism (the distribution speed of the conveying mechanism falls within the scope of the present application and can be seen by referring to the drawings, and thus no further description is given) is arranged on the rear side of the frame 1, and a cutting mechanism is arranged on the front side of the frame 1. Figs. 1-2 A plurality of clamping members are arranged on the conveying mechanism at equal intervals, the clamping members are used to receive the guided-in cocoon, and the conveying mechanism conveys the cocoon to the cutting mechanism on the front side to realize the cutting.

[0027] The conveying mechanism comprises pulleys 16 at both ends and a conveying belt 3 wrapped around the pulleys 16 and forming a closed state, one of the pulleys 16 is driven to rotate by a first motor 2. Each clamping member is fixedly connected to the conveying belt 3.

[0028] The cutting mechanism is a conventional structure of a cutting knife 13 driven by a second motor 12, the second motor 12 is installed on the frame 1 and the output end is vertically downward, the output end of the motor is connected with the cutting knife 13 and is arranged above the clamping member passing through.

[0029] As shown in the drawings, the clamping member is a clamping seat 5, the clamping seat 5 is fixedly connected to the conveying belt 3 and is arranged on the conveying belt 3 at equal intervals. Figs. 3-5As shown, the opening of the clamping member is formed with an oblique cut, which is rotated to an inclined state before it is conducted to the cutting position, so that the cutting knife 13 cuts the inclined cocoon, and the size of the inclined cut on the top of the cocoon is larger than that of the horizontal cut, so that the internal silkworm pupa is more easily separated from the cocoon and the internal silkworm pupa is not easily damaged. The oblique cut on the clamping member after being inclined is in close contact with the cutting knife 13 to achieve cutting (the specific position can be referred to the drawing) Fig. 6 ).

[0030] Considering that the size of the cocoon is different, it is necessary to stably clamp cocoon of different sizes. The clamping member is designed in the scheme, which includes a first clamping seat 5 and a second clamping seat 6 which are independent of each other. The inner sides of the first clamping seat 5 and the second clamping seat 6 are respectively provided with notches, and together form a placing entrance 7, wherein the oblique notch is provided at the top of the first clamping seat 5 and the second clamping seat 6.

[0031] The first clamping seat 5 and the second clamping seat 6 need to be switched to an inclined state, so a fixed block 8 is installed on the conveying belt 3, the first clamping seat 5 is pivoted to the fixed block 8, the other side of the conveying belt 3 is slidingly connected with a movable block 9 (slidingly connected through a sliding groove 11), and the second clamping seat 6 is pivoted to the sliding block. Secondly, a connecting block 17 is installed on the front side of the first clamping seat 5 and the second clamping seat 6 respectively, and a spring 18 is fixedly connected between the two connecting blocks 17. Under normal circumstances, the first clamping seat 5 and the second clamping seat 6 form a certain gap under the action of the spring 18, so that the size of the placing entrance 7 is slightly larger, which is easier to place the cocoon, and when the second clamping seat 6 moves inward to abut against the first clamping seat 5 under the action of horizontal external force, the cocoon can be stably clamped.

[0032] The upper end of the rack 1 and located on one side of the conveying belt 3 is provided with a control plate 4, and the control plate 4 is provided with a negative pressure machine 15. The lower side output end of the negative pressure machine 15 is provided with a cladding suction seat 14, and the cladding suction seat 14 is located directly above the clamping member. The control plate 4 cooperates with the cladding suction seat 14 to finely adjust the height of the cocoon in the clamping member, so that some silkworm pupae inside the cocoon are not cut by the cutting knife 13. At the same time, the control plate 4 can also drive the clamping member to rotate and incline at the front end.

[0033] Specifically, as shown in the drawing Figs. 4-5 , the bottom of the front end position of the control plate 4 extends a base, and the rear side of the base is provided with a connecting oblique groove 42. The base is slightly outside the movable block 9 under normal circumstances, and when the movable block 9 passes through the connecting oblique groove 42, it is pressed inward, so that the second clamping seat 6 moves to the first clamping seat 5 to clamp the cocoon.

[0034] The adjusting mode of the inclined state of the clamping member is that a guide rod 19 is arranged between the two connecting blocks 17 of the same clamping member, the guide rod 19 is fixedly connected with the connecting block 17 at the first clamping seat 5, and the other side is slidingly connected with the connecting block 17 at the second clamping seat 6 and penetrates through. The guide rod 19 is normally supported on the edge of the control plate 4, and a sinking inclined groove 43 is arranged at the front end of the control plate 4, so that the guide rod 19 is moved downward to realize the deflection of the whole clamping member.

[0035] Due to the structural design, in order to keep the whole clamping member balanced during movement, the weight 10 is fixedly connected at the rear side of the first clamping seat 5 and the second clamping seat 6, so that the center of gravity of the clamping member is slightly offset to the rear side, preventing the problem of overturning.

[0036] A conventional near-infrared diffuse transmission structure of "light source + integrating sphere + spectrometer" is further arranged below the negative pressure machine 15, which is used for quickly detecting the position of the silkworm pupa inside the cocoon without damaging the cocoon.

[0037] It should be noted that the near-infrared diffuse transmission structure and the cladding suction seat 14 are respectively located at the clamping member after overturning, and the connecting inclined groove 42 is located at the opposite front side of the cladding suction seat 14, so that after adjusting the height of the cocoon (the height is adjusted by adsorbing the cocoon upward when the cocoon is not clamped, and the cutout needs to be as large as possible), the clamping member is translated to the connecting inclined groove 42 to clamp (suspended clamping) the cocoon. The coverage range of the cladding suction seat 14 is from the cocoon after overturning to before being clamped.

[0038] When the clamping member is located directly below the cladding suction seat 14, the movement needs to be temporarily stopped to facilitate height adjustment.

[0039] The above-described specific embodiments further illustrate the purpose, technical solutions and beneficial effects of the present application. It should be understood that the above-described specific embodiments are only for the specific embodiments of the present application and are not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
