Description

Technical Field

[0001] The invention relates to the technical field of cocoon processing equipment, in particular to a clamp and a cocoon cutting machine. Background Art

[0002] Tussah cocoons are cocoons made by tussah silkworms, including the cocoon shell and the cocoon pupa inside the cocoon shell. As a food ingredient, the cocoon pupa is rich in nutrients such as protein and vitamins. In order to take the cocoon pupa out of the cocoon shell, one end of the cocoon shell is usually cut and then the cocoon pupa is taken out.

[0003] At present, the cocoon cutting operation in most areas still relies on manual operation, which has the problem of low efficiency. In order to improve efficiency, various cocoon cutting machines have been developed to realize mechanized cocoon cutting operation. However, the cocoon clamps of the cocoon cutting machines have the problem of unstable clamping effect, which causes the cocoon shell to rotate in the clamp during the cocoon cutting process, and the cutting knife cannot effectively cut the cocoon shell chips, so the cocoon pupa cannot be taken out. Summary of the invention

[0004] The purpose of the present invention is to provide a clamp and a cocoon cutting machine to address the defects in the above-mentioned technology, so as to stably clamp the cocoon shell through the clamping pieces of the clamp, ensure the stability of the cocoon shell during the cocoon cutting operation, and improve the success rate of cocoon cutting and the operation efficiency.

[0005] The object of the present invention is achieved in that: In a first aspect, the present application provides a clamp, which is mainly used for fixing tussah cocoons during the cocoon cutting process, and the clamp comprises a clamping seat and a plurality of clips arranged along the circumference of the clamping seat, and the clips are rotatably connected to the clamping seat; wherein, The clamping seat is provided with a receiving cavity with one end open; the bottom of the receiving cavity is provided with a first elastic member acting on the plurality of clips; A sleeve is sleeved on the outside of the clamping seat, the sleeve is slidably connected to the clamping seat, and a first anti-slip portion is provided on the upper part of the clamping seat for preventing the sleeve from slipping out; A second elastic member is provided at one end of the sleeve away from the first anti-slip portion, one end of the second elastic member abuts against the sleeve, and the other end is fixedly arranged; the second elastic member is used to make the sleeve abut against the first anti-slip portion; The elastic force of the second elastic member is greater than the elastic force of the first elastic member.

[0006] In the above scheme, when the sleeve is compressed to compress the second elastic member, the sleeve slides along the clamping seat and moves away from the first anti-slip portion.

During the resetting process of the sleeve, the multiple clips are driven to embrace the outside of the cocoon, and the cocoon is clamped at multiple points by the multiple clips. Since the cocoon shell of the tussah cocoon has a certain hardness and elasticity, the cocoon shell in contact with the clip will be slightly deformed, thereby achieving stable clamping of the cocoon by the clamp, preventing the cocoon shell from rotating relative to the clamp during the cocoon cutting process, and improving the success rate of cocoon cutting.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] To facilitate understanding of the clamp and cocoon cutting machine provided in the embodiment of the present application, their application scenarios are first described. The clamp and cocoon cutting machine of the present application are mainly suitable for clamping and cutting cocoons of tussah silkworm cocoons. The multiple clamping pieces of the clamp form a stable clamp on the cocoon shell to prevent the cocoon shell from rotating during the cocoon cutting operation of the cocoon cutting machine. The problem of unstable clamping of the cocoon shell by the clamp in the prior art, rotation of the cocoon shell during the cocoon cutting process, easy failure of cocoon cutting, and inability to remove the cocoon pupa in the cocoon shell is solved, thereby improving production efficiency.

[0021] Depend on Figure 1 — Figure 4 In the first aspect, the present application provides a clamp, which is mainly used for fixing tussah cocoons 2 during the cocoon cutting process. Figure 1 The clamp includes a clamping seat 11 and a plurality of clips 12 arranged along the circumference of the clamping seat 11, and the clips 12 are rotatably connected to the clamping seat 11. In order to ensure the stability of clamping, in this embodiment, the plurality of clips 12 are evenly arranged along the circumference of the axis of the clamping seat 11 to ensure the uniformity of the force on the cocoon shell in all directions, so as to prevent the cocoon shell from being deformed due to the local force concentration.

[0022] In order to place the silk cocoon 2 in the clamp and stably clamp the cocoon shell of the silk cocoon 2, the clamp 12 in the present application is rotatably connected to the clamp seat 11. For ease of understanding, the two ends of the clamp 12 along the axis of the clamp seat 11 are named as the first end 121 and the second end 122 in this embodiment. The end where the silk cocoon 2 is placed is the first end 121, and the other end is the second end 122. The clamp 12 is rotatably connected to the clamp seat 11 through a rotating shaft, wherein the rotating shaft can be a shaft body embedded in the clamp seat 11, or a shaft body elastically clamped to the clamp seat 11, and the clamp 12 can rotate relative to the clamp seat 11 around the rotating shaft.

[0023] See also Figure 2 , Figure 2 This is a schematic diagram of the cross-sectional structure of the clamping clip 12 of the present application in the open state, and the clip 12 is rotatably connected to the clamping seat 11. The clip 12 uses the rotating shaft as a fulcrum, and when the first end 121 is away from the axis of the clamping seat 11, the second end 122 is close to the axis of the clamping seat 11, and the clip 12 is in an open state; when the first end 121 is close to the axis of the clamping seat 11, the second end 122 is away from the axis of the clamping seat 11, and the clip 12 is in a closed state.

[0024] The clamping seat 11 is provided with a receiving cavity 111 with an opening 113 at one end. The receiving cavity 111 can receive the silk cocoon 2. In this embodiment, a plurality of clips 12 are arranged along the circumference of the receiving cavity 111. The silk cocoon 2 is placed in the receiving cavity 111, and the cocoon shell of the silk cocoon 2 is embraced and clamped by the plurality of clips 12. In order to enable the plurality of clips 12 to be opened when the silk cocoon 2 is placed, the present application provides a first elastic member 13 acting on the plurality of clips 12 at the bottom of the receiving cavity 111. The first elastic member 13 can be a spring or an elastic rubber ring. When the first elastic member 13 is a spring, the spring elastically abuts against the clip 12; when the first elastic member 13 is an elastic rubber ring, the elastic rubber ring is wound around the second end 122 of the clip 12, so that the second end 122 of the clip 12 has a tendency to converge toward the axis of the clamping seat 11. When the limit around the first end 121 of the clip 12 is released, the clip 12 rotates around the rotation axis as a fulcrum under the elastic force of the first elastic member 13 , so that the first end 121 of the clip 12 is in an open state.

[0025] In order to enable the clip 12 to be able to timely embrace and fix the cocoon 2 after the cocoon 2 is placed in the accommodating cavity 111 of the clamping seat 11, the present application sets a sleeve 14 on the outside of the clamping seat 11, the sleeve 14 is slidably connected to the clamping seat 11, and the upper part of the clamping seat 11 is provided with a first anti-slip portion 112 for preventing the sleeve 14 from slipping out. It should be noted that in this embodiment, the sleeve 14 is slidably connected to the clamping seat 11, which means that the inner hole of the sleeve 14 and the outer wall of the clamping seat 11 are in clearance fit, so that the sleeve 14 can slide along the outer wall of the clamping seat 11. A first anti-slip portion 112 is provided on the upper portion of the clamping seat 11, wherein the first anti-slip portion 112 can be provided integrally with the clamping seat 11, such as the upper diameter of the clamping seat 11 is larger than the inner diameter of the sleeve 14, or a top screw or other component is provided on the upper portion of the clamping seat 11, and the sleeve 14 is prevented from slipping out of the clamping seat 11 by the top screw; the first anti-slip portion 112 can also be provided separately from the clamping seat 11, in order to prevent the sleeve 14 from slipping out of the clamping seat 11. In this embodiment, the upper portion of the clamping seat 11 refers to the side of the clamping seat 11 close to the opening 113 of the accommodating cavity 111.

[0026] Reference Figure 3 In this embodiment, the sleeve 14 abuts against the side of the clip 12 away from the axis direction of the clamping seat 11, so that the clip 12 rotates along the rotating shaft, and the first end 121 of the clip 12 gathers toward the axis direction of the clamping seat 11, so that the clip 12 clamps the cocoon 2. In order to enable the sleeve 14 to slide toward the opening 113 end of the accommodating cavity 111 of the clamping seat 11 when the clip 12 is needed to clamp the cocoon 2, the sleeve 14 of the present application is provided with a second elastic member 15 at one end away from the first anti-slip portion 112, and one end of the second elastic member 15 abuts against the sleeve 14, and the other end is fixedly set. The fixed end of the second elastic member 15 can be provided by setting a ring platform or a baffle on the outside of the clamping seat 11, so that the second elastic member 15 abuts against the ring platform or the baffle. The sleeve 14 is abutted against the first anti-slip portion 112 by the elastic force of the second elastic member 15, and at the same time, the sleeve 14 makes multiple clips 12 in a hugging state. The elastic force of the second elastic member 15 is greater than the elastic force of the first elastic member 13 , ensuring that the sleeve 14 can overcome the resistance of the first elastic member 13 and push the clip 12 to embrace.

[0027] In the above scheme, when the sleeve 14 is pressed to compress the second elastic member 15, the sleeve 14 slides along the clamping seat 11 and moves away from the first anti-slip portion 112. At this time, the sleeve 14 releases the restraint on the upper part of the clip 12. Under the action of the first elastic member 13, the ends of the multiple clips 12 close to the first anti-slip portion 112 are in an open state, and the cocoon 2 can be placed in the accommodating cavity 111 of the clamp. The pressure for the sleeve 14 to slide toward the second elastic member 15 can be provided by the power member of the electric push rod or the cylinder. The power member directly or indirectly pushes the end of the sleeve 14 to compress the second elastic member 15, and the sleeve 14 slides toward the second elastic member 15. When the sleeve 14 is released from pressure, under the action of the second elastic member 15, the sleeve 14 is reset and abuts against the first anti-slip portion 112. During the reset process of the sleeve 14, the multiple clips 12 are driven to embrace the outside of the cocoon 2, and the cocoon 2 is clamped at multiple points by the multiple clips 12. Since the cocoon shell of the tussah cocoon 2 has a certain hardness and elasticity, the cocoon shell in contact with the clamp 12 will be slightly deformed, thereby achieving stable clamping of the cocoon 2 by the clamp, preventing the cocoon shell from rotating relative to the clamp during the cocoon cutting process, and improving the success rate of cocoon cutting.

[0028] In an optional embodiment, the clamping seat 11 is provided with a plurality of openings 113 on its circumference, and the clips 12 are embedded and installed in the openings 113. In this embodiment, the clips 12 are in the form of sheets, and their thickness can be 2 mm, 3 mm, 4 mm, etc., and the cocoons 2 are clamped by the sides of the clips 12. Since the thickness of the clips 12 is relatively small, the clamping force is improved, and the clamping stability of the cocoons 2 is ensured. The plurality of openings 113 provided on the circumference of the clamping seat 11 are preferably evenly arranged along the circumference of the clamping seat 11, so that the plurality of clips 12 are also evenly arranged along the circumference of the clamping seat 11, ensuring that a uniform clamping force is applied to the cocoon shell of the cocoon 2 in all directions, preventing the cocoon shell from being subjected to uneven force, causing excessive local deformation, resulting in large pits in the cocoon shell, and injuring the cocoon pupa in the cocoon shell, and the deformed cocoon shell is not conducive to cutting.

[0029] In addition, the clip 12 is embedded in the opening 113. Since the clamping seat 11 has a certain wall thickness, the side of the opening 113 can limit the clip 12, prevent the clip 12 from tilting during the rotation process, and improve the clamping stability of the clip 12 on the cocoon 2.

[0030] In an optional embodiment, in order to realize the rotation of the clip 12 relative to the clamping seat 11, a first annular groove 114 is provided in the clamping seat 11, and a groove 123 is provided on the side of the clip 12 close to the axis of the clamping seat 11. The clip 15 is clamped in the first annular groove 114 and the groove 123 at the same time. As an example, the clip 15 in this embodiment is a ring-shaped steel wire clip 15, and an opening 113 for the clip 15 to open and close is provided on the clip 15. The clip 15 is used as a rotating shaft for the clip 12 to rotate, which is convenient for installation, and through the tension of the clip 15, multiple clips 12 can be fixed on the clamping seat 11 by rotating around the clip 15.

[0031] In an optional embodiment, a slope 124 is provided on the side of the upper part of the clip 12 away from the axis of the clamping seat 11, and the slope 124 is inclined from bottom to top in a direction away from the axis of the clamping seat 11. The upper part of the clip 12 in this embodiment refers to the end of the clip 12 close to the first anti-slip portion 112 of the clamping seat 11, and the slope 124 is provided on the side of the clip 12 close to the sleeve 14. The slope 124 is provided on the upper part of the clip 12. When the clip 12 is in an embracing state, the sleeve 14 abuts against the slope 124 of the clip 12, which ensures the effective fixation of the cocoon 2 while effectively reducing the width of the clip 12 below the slope 124, preventing the sleeve 14 from being pressed down. When the clip 12 is in an open state, the clip 12 and the sleeve 14 interfere with each other, resulting in an insufficient opening angle of the clip 12. In addition, it can also reduce the wall thickness of the clamping seat 11 and save materials.

[0032] In an alternative embodiment, referring to Figure 2 , Figure 3 In order to ensure that the clip 12 can be opened smoothly, an arc surface 125 is provided at the lower part of the clip 12, and an anti-slip portion 126 is provided at the bottom of the arc surface 125. The lower part of the clip 12 refers to the end of the clip 12 close to the second end 122, and the arc surface 125 is provided on the side of the clip 12 away from the axis of the clamping seat 11. At this time, the first elastic member 13 is a first spring, one end of the first spring abuts against the bottom of the accommodating cavity 111, and the other end abuts against the arc surface 125. It should be noted that in this embodiment, the first spring is a compression spring, which has a tendency to stretch.

[0033] When the sleeve 14 is pressed and slides downward, the sleeve 14 loses its restraint on the upper part of the clip 12. Under the elastic force of the first spring, the second end 122 of the clip 12 moves toward the axis of the clamping seat 11, and the first end 121 of the clip 12 moves away from the axis of the clamping seat 11, and the clip 12 is in an open state. The arc surface 125 allows the clip 12 to slide smoothly with the first spring.

[0034] In an optional embodiment, the second elastic member 15 is a second spring. In order to facilitate the installation of the second spring and the sleeve 14 on the clamping seat 11, a second annular groove 115 is provided at the lower part of the clamping seat 11, and the second annular groove 115 is clamped with an elastic sheet. In the present application, the elastic sheet is in the shape of a flat sheet and can be elastically opened and closed. After the sleeve 14 and the second spring are sequentially mounted on the clamping seat 11, the elastic sheet is clamped in the second annular groove 115 for easy installation. At this time, one end of the second spring abuts against the elastic sheet, and the other end abuts against the end of the sleeve 14.

[0035] Second, refer to Figure 5-Figure 13 The present application provides a cocoon cutting machine, which includes the clamp 1 in the above scheme, and the cocoon 2 is stably clamped by the clamp 1 to solve the problem of the cocoon 2 rotating during the cocoon cutting process. The cocoon cutting machine of the present application also includes a control system, a frame 3 and a turntable 4 rotatably connected to the frame 3. The frame 3 is used to install the relevant components required for the cocoon cutting machine. As an example, the frame 3 includes a panel 32 and a frame 31, and the panel 32 is placed on the top of the frame 31. The panel 32 is provided with a rectangular or other shaped hole for partially exposing the turntable 4 above the panel 32.

[0036] As an example, in order to realize the rotational connection between the turntable 4 and the frame 3, a motor 5 can be fixedly connected to the frame 3, and the output shaft of the motor 5 is fixedly connected to the turntable 4. When the output shaft of the motor 5 rotates, the turntable 4 rotates with the output shaft of the motor 5.

[0037] A plurality of clamps 1 are arranged around the circumference of the turntable 4, and the cocoons 2 are clamped by the plurality of clamps 1 to achieve mechanized cocoon cutting. During the cocoon cutting operation, the cutting assembly 6 needs to cut the cocoons in all directions in the circumferential direction. Therefore, in the present application, the clamp 1 is rotatably connected to the turntable 4. During the cocoon cutting operation, the clamp 1 drives the cocoons 2 to rotate, so that the cutting assembly 6 can achieve comprehensive circumferential cutting of the cocoons. In order to realize the rotation of the clamp 1 relative to the turntable 4, a driving mechanism 8 for driving the clamp 1 to rotate relative to the turntable 4 is provided in the present application. A cutting assembly 6 for cutting cocoons is provided on the frame 3. When the clamp 1 clamping the cocoon 2 moves to a position corresponding to the cutting assembly 6, the driving mechanism 8 acts on the clamp 1 to drive the clamp 1 to rotate. While the clamp 1 rotates relative to the turntable 4, the cutting assembly 6 cuts the cocoon shell.

[0038] In order to load the cocoons into the holder 1 and remove the cut cocoon shells from the holder 1, the present application also sets an opening component 7 on the frame 3, and the opening component 7 is placed outside the rotation path of the holder 1 (i.e., the rotation path of the holder 1 rotating with the turntable 4). When the holder 1 runs to the corresponding position, the sleeve 14 of the holder 1 is pressed by the opening component 7, so that the clamping piece 12 of the holder 1 is in an open state. At this time, on the one hand, the silkworm cocoon 2 can be placed in the accommodating cavity 111 of the holder 1; on the other hand, the cocoon shell originally clamped in the holder 1 can be taken out under the action of gravity or other external forces.

[0039] The control system in the present application can be a PLC controller or other programmable controller, which controls the rotation of the turntable 4 and the operation of the driving mechanism 8 and the opening component 7 to achieve automatic cocoon cutting.

[0040] In order to facilitate the understanding of the present application of the cocoon cutting machine and its operation process, the following Fig. 9 The working mode of the cocoon cutting machine of the present application is described. As an example, the cocoon cutting machine of the present application presets a cocoon loading position, a cocoon cutting position and a cocoon withdrawing position.

[0041] like Fig. 9 As shown, the cocoon loading position is provided with an opening component 7. When the turntable 4 drives the clamp 1 to rotate to the cocoon cutting position, the turntable 4 stops rotating, and the clamp 1 stays at the cocoon loading position. The opening component 7 operates, presses the sleeve 14 of the clamp 1, and makes the sleeve 14 slide along the clamping seat 11. At this time, the plurality of clips 12 are in an open state, and the cocoon 2 can be placed in the clamp 1. After the cocoon 2 is placed, the opening component 7 releases the pressing of the sleeve 14, and the sleeve 14 is reset under the action of the second elastic member 15 and drives the clips 12 to clamp the cocoon shell. In order to place the cocoon 2 in the clamp 1, the pressing time of the opening component 7 on the sleeve 14 and the staying time of the turntable 4 can be set, such as 1 second, 2 seconds, etc., wherein the staying time can be slightly greater than the pressing time. The operator needs to place the silkworm cocoon 2 into the clamp 1 within the set pressing time. After the pressing time is over, the opening assembly 7 releases the pressing on the sleeve 14, and the sleeve 14 is reset to allow the clamp 12 to clamp the cocoon shell.

[0042] Continue to refer to Fig. 9 After the cocoon 2 is clamped in the clamp 1, the motor 5 continues to rotate, driving the turntable 4 to rotate, and the turntable 4 drives the clamp 1 to rotate to the cocoon cutting position. The frame 3 is correspondingly provided with a cutting assembly 6 and a driving mechanism 8 at the cocoon cutting position. When the clamp 1 clamping the cocoon 2 rotates to the cocoon cutting position, the turntable 4 stops rotating, and the clamp 1 clamping the cocoon 2 stays at the cocoon cutting position. At this time, the cocoon shell contacts the cocoon cutting knife in the cutting assembly 6, and the clamp 1 is connected to the driving mechanism 8. The driving mechanism 8 drives the clamp 1 clamping the cocoon 2 to rotate. When the clamp 1 rotates, the cocoon cutting knife in the cutting assembly 6 completes the cutting of the cocoon shell in the circumferential direction.

[0043] In order to facilitate loading cocoons into the holder 1 and observing the cocoon cutting state, the cocoon loading position and the cocoon cutting position are both arranged above the panel 32 in this embodiment.

[0044] Continue to refer to Fig. 9 After the cocoon cutting is completed, the rotating disk 4 continues to rotate. As the rotating disk 4 rotates, the clamp 1 with the cocoon cutting completed rotates to the cocoon retreating position. In order to facilitate the cocoon retreating, the cocoon retreating position in this embodiment is arranged on the side of the rotating disk 4 close to the ground. The cocoon shell after the cocoon cutting is completed will have an annular incision. In the process of the clamp 1 rotating from the cocoon cutting position to the cocoon retreating position, the annular incision faces the ground, and the cocoon pupa in the cocoon shell falls from the annular incision of the cocoon shell under the action of gravity. The above-mentioned annular incision faces the ground, which does not necessarily mean that the annular incision is directly facing the ground, and there may also be a certain inclination angle. After the clamp 1 rotates to the cocoon retreating position, the rotating disk 4 stops rotating, and the clamp 1 stays in the cocoon retreating position. In order to realize the smooth cocoon retreating, the opening component 7 is also arranged at the cocoon retreating position in this embodiment, and the sleeve 14 of the clamp 1 is pressed by the opening component 7 to make the clamp 12 in an open state. At this time, the cocoon shell can be dropped from the clamp 1 by external force or relying on the weight of the cocoon shell itself, and the cocoon retreating is completed. This step can also set the dwell time of the turntable 4 and the pressing time of the opening component 7.

[0045] According to the above described steps, the cocoon cutting machine completes the automatic cocoon cutting operation and improves the production efficiency. It should be noted that, in order to facilitate programming, the multiple clamps 1 connected to the turntable 4 in the present application are evenly arranged along the circumference of the turntable 4. In order to facilitate control, the motor 5 driving the turntable 4 to rotate can rotate a stepper motor 5, a servo motor 5, etc., and the cocoon cutting efficiency can be adjusted by controlling the parameters such as the rotation speed of the turntable 4 and the residence time of the turntable 4.

[0046] In order to make the opening angles of each of the multiple clips 12 as similar as possible when the multiple clips 12 are in the open state, two opening components 7 are respectively arranged at the cocoon loading position and the cocoon unloading position in this embodiment, and the two opening components 7 are respectively arranged at both sides of the clamp 1. By pressing both sides of the sleeve 14 at the same time, the sleeve 14 does not tilt during the sliding process, and the multiple clips 12 have the same opening angles. This can prevent the opening angles of the multiple clips 12 from being different, and the cocoon 2 from being tilted after clamping the cocoon 2, which affects the subsequent cutting of the cocoon shell.

[0047] In an optional embodiment, since the cocoon shells of different silk cocoons 2 may have different sizes, the blade 64 of the cutting assembly 6 in the present application is in elastic contact with the cocoon shell to adapt to cocoons 2 of different sizes. Fig.10The cutting assembly 6 includes a base 61 fixedly connected to the frame 3, and an elastic sheet 62 connected to the base 61 at one end, and the other end of the elastic sheet 62 is connected to a knife clamp 63, and the knife clamp 63 clamps a blade 64 and is suspended outside the path of the holder 1 rotating with the turntable 4. At the same time, an elastic support member 65 is fixedly provided on the side of the knife clamp 63 away from the holder 1, and the elastic support member 65 elastically abuts against the knife clamp 63.

[0048] As an example, the spring sheet 62 can be made of a thin steel sheet with a certain elasticity, or other thin sheets with elastic materials. The spring sheet 62 serves as a swing arm of the knife clamp 63. With the different diameters of the cocoon shell, the spring sheet 62 produces elastic deformation with a corresponding amplitude. The cocoon shell is elastically contacted with the blade 64, and the knife clamp 63 and other components are prevented from rigidly contacting the cocoon shell, thereby reducing the rotation resistance of the cocoon shell. The cocoon shell is prevented from rotating in the clamp 1 during the cocoon cutting process, thereby improving the stability of the cocoon cutting operation.

[0049] In order to further optimize the structure of the cutting assembly 6 and improve the stability of the clamping device 1 on the cocoon 2 during the cocoon cutting operation. In this embodiment, the spring piece 62 is tilted, and the direction from the base 61 to the clamping device 63 gradually approaches the rotation path of the clamp 1. Even if the cocoon shell contacts the spring piece 62, the spring piece 62 can reduce the resistance and improve the clamping stability after being tilted. The spring piece 62 is tilted, and the contact surface between the base 61 and the spring piece 62 is set to an inclined surface 124 with the same tilt angle as the spring piece 62. The base 61 can also be tilted and installed on the frame 3 to make the spring piece 62 tilted.

[0050] In order to prevent the cutting assembly 6 from causing a large rotational resistance to the cocoon shell and improve the clamping stability, as an example, in this embodiment, the side of the knife clamp 63 that clamps the blade 64 is a second arc surface 631125, and the blade 64 is placed on the second arc surface 631125 close to the highest point of the rotation path of the clamp 1. The second arc surface 631125 contacts the cocoon shell to reduce the rotational resistance of the cocoon shell.

[0051] The function of the elastic support member 65 in the present application is to provide sufficient support force for the blade 64, so that the blade 64 can elastically abut against the cocoon shell, and at the same time, provide a certain pressure on the blade 64, so that the blade 64 can cut the cocoon shell. As an example, the elastic support member 65 in the present application includes a sleeve 651 and an ejector pin 652, wherein the ejector pin 652 is inserted into the sleeve 651, and a spring is also provided between the ejector pin 652 and the bottom of the sleeve 651, and an elastic support force is provided for the ejector pin 652 through the spring. The other end of the ejector pin 652 abuts against the side of the knife clamp 63 away from the rotation path of the clamp 1, and when cutting the cocoon, the ejector pin 652 abuts against the knife clamp 63 to provide support force for the blade 64. The sleeve 651 is connected to the frame 3 by a thread, and then locked by a nut 653. The support force of the elastic support member 65 on the blade 64 can be indirectly adjusted by adjusting the protruding length of the sleeve 651, thereby adjusting the abutment amplitude of the ejector pin 652 on the knife clamp 63.

[0052] In an alternative embodiment, referring to Figure 11-13 In order to realize the connection between the turntable 4 and the clamp 1, the present application arranges a plurality of support seats 41 on the circumference of the turntable 4, and the plurality of support seats 41 are preferably arranged evenly along the circumference of the turntable 4, so as to facilitate the programming of the control system. The support seat 41 can be fixedly installed on the turntable 4 by bolts, locating pins and other components. In order to rotatably connect the clamp 1 and the support seat 41, a fixed shaft 116 is provided at the bottom of the clamp seat 11 of the clamp 1, and the fixed shaft 116 is sleeved with a bearing 43 seat 42, and the fixed shaft 116 is rotatably connected to the bearing 43 seat 42. In order to improve the smoothness of rotation, a bearing 43 can be arranged in the bearing 43 seat 42, and the bearing 43 is connected between the fixed shaft 116 and the bearing 43 seat 42. Among them, the bearing 43 can be fixed in the bearing 43 seat 42 by means of a retaining ring and other components through a hole.

[0053] In order to connect the bearing 43 seat 42 with the support seat 41, the present application has multiple through holes arranged on the circumference of the bearing 43 seat 42, and bolts are arranged in the through holes to fix the bearing 43 seat 42 with the support seat 41. Since the clamp 1 can rotate relative to the bearing 43 seat 42, and the bearing 43 seat 42 is fixedly connected to the support seat 41, the clamp 1 is rotatably connected to the turntable 4.

[0054] In an optional embodiment, in order to realize the rotation of the clamp 1 relative to the turntable 4 at the cocoon cutting position, the present application further sleeves the first friction wheel 44 on the fixed shaft 116, and the first friction wheel 44 abuts against the bearing 43 seat 42 and is fixedly connected to the fixed shaft 116. The first friction wheel 44 and the fixed shaft 116 can be fixedly connected by components such as a top bolt, so that the clamp 1 can rotate with the first friction wheel 44.

[0055] In order to drive the first friction wheel 44 to rotate, the driving mechanism 8 includes a motor 5 fixedly connected to the frame 3, and a second friction wheel 81 connected to the output end of the motor 5. When the clamp 1 rotates to the cocoon cutting position with the turntable 4, the first friction wheel 44 contacts the second friction wheel 81. Utilizing the friction between the two wheels, when the second friction wheel 81 rotates, the first friction wheel 44 rotates accordingly, thereby driving the clamp 1 to rotate. As an example, in this embodiment, the first friction wheel 44 is made of metal material, and in order to increase the friction, a groove 123 can be set on the outer surface of the first friction wheel 44. The second friction wheel 81 can be made of a hard rubber material with a certain elasticity. When the two friction wheels are in contact, the elastic deformation of the elastic material can increase the friction between the two friction wheels.

[0056] In an optional embodiment, in order to facilitate the connection between each component and the frame 3, the frame 3 of the present application includes a first side plate 33 and a second side plate 34. Figure 5 , Figure 7 The first side plate 33 and the second side plate 34 are connected to the frame 31 of the frame 3 through a screw 35, and a plurality of nuts are provided on the screw 35. The plurality of nuts limit the distance between the first side plate 33 and the second side plate 34, thereby achieving an adjustable distance between the first side plate 33 and the second side plate 34, which facilitates the installation of related components.

[0057] As an example, in the present application, the opening assembly 7 and the cutting assembly 6 are both installed on the first side plate 33 and / or the second side plate 34 and are fixedly connected by bolts and other connecting parts.

[0058] In the board application, the turntable 4 is rotatably connected to the first side plate 33, the motor 5 connected to the turntable 4 is fixedly connected to the first side plate 33, and the turntable 4 is connected to the output shaft of the motor 5, thereby realizing the rotatable connection between the turntable 4 and the first side plate 33.

[0059] In an optional embodiment, in order to smoothly withdraw the cut cocoon shell at the cocoon withdrawal position, the present application provides a cocoon top assembly 9. The cocoon top assembly 9 includes a fixedly arranged telescopic drive member 91, and a push rod 92 arranged corresponding to the telescopic drive member 91. As an example, the telescopic drive member 91 can be a cylinder, and a push plate 94 is connected to the cylinder rod end of the cylinder. When the clamp 1 rotates to the cocoon withdrawal position with the turntable 4, the cylinder runs, driving the push plate 94 to abut against the push rod 92, and pushing the push rod 92 to hold the cocoon shell in the clamp 1, so that the cocoon shell is pushed out by force. In this embodiment, the top plate 94 may not be provided, and the push rod 92 may be directly pushed to move by the cylinder rod of the cylinder.

[0060] In order to ensure the stable operation of the push rod 92, a through hole is provided at the bottom of the clamping seat 11 of the clamp 1, and the push rod 92 is inserted into the through hole. The two ends of the push rod 92 are provided with second anti-slip portions 921 with a diameter larger than the through hole, and the push rod 92 is restricted in the through hole by the second anti-slip portions 921. One or two of the second anti-slip portions 921 can be detachably connected to the push rod 92, such as being connected to the push rod 92 by threads or the like.

[0061] After the cocoon is unwound, the push rod 92 needs to be reset. In the present application, the reset of the push rod 92 is achieved by the third spring 93. The third spring 93 is sleeved on the side of the push rod 92 close to the telescopic drive member 91, one end of the third spring 93 abuts against the clamping seat 11, and the other end abuts against the second anti-slip portion 921 of the push rod 92. When the cylinder completes the cocoon unwound work, the cylinder contracts, and under the action of the third spring 93, the push rod 92 slides toward the telescopic drive member 91 to reset.
