Description

Technical Field

[0001] The utility model relates to a silkworm breeding machine, in particular to a telescopic silkworm foil clamping mechanism. Background Art

[0002] my country has a long history of silk culture and silkworm breeding. At present, silkworm breeding is still mainly operated by manual operation, supplemented by mechanical operation, which is difficult to adapt to the development of modern agriculture. It is urgent to improve the mechanization and automation level of silkworm breeding. At the same time, silkworm breeding is showing a trend of large-scale operation, which requires equipment with a higher degree of mechanization and automation, changing the labor-intensive production mode, reducing labor intensity, improving production and management efficiency, realizing industrial transformation and upgrading, and promoting high-quality development of the industry.

[0003] A fully automatic silkworm raising robot system for mulberry feeding CN2023118298372 and a fully automatic silkworm raising machine CN2021223431549 use a six-axis manipulator to stack silkworm foil. The six-axis manipulator has six degrees of freedom, but the silkworm foil stacking operation does not require so many degrees of freedom, so a two-degree-of-freedom special stacking device is more suitable for silkworm raising and stacking silkworm foil; at the same time, the stacked silkworm foil needs to be manually transferred, specifically, the piles of silkworm foil to be raised need to be manually transferred to the equipment station, and the piles of silkworm foil that have been raised need to be manually transferred from the equipment station to the silkworm room; in addition, both patents are for mulberry leaf silkworm raising, and do not involve feed silkworm raising.

[0004] Silkworm feeding and transmission platform CN2019201033689, this patent is an early application of the inventor, which proposes horizontal conveying of silkworm foil and silkworm feeding operation during the movement of silkworm foil. This equipment requires manual silkworm foil stacking operation, and the degree of automation is low.

[0005] After long-term research, the inventor has developed an automated silkworm breeding equipment. Based on the transportation of the AGV trolley, it can move to the designated position of the silkworm room, so as to transport the silkworm foil to the silkworm breeding area, grab the silkworm foil by a robot, and place it on the silkworm breeding line. After the silkworms are raised, the silkworm foil is grabbed and placed in the designated position, and then the AGV trolley transports the silkworm foil to the silkworm room, thereby realizing automated silkworm breeding. In the process of grabbing the silkworm foil, the taking and placing of the silkworm foil is involved. Since there are silkworms in the silkworm foil, it is not feasible to grab it by suction cup adsorption. Instead, a double-headed gripper cylinder is used to realize the approach and separation of the two clamping units. Since the stroke of the double-headed gripper cylinder is relatively fixed and the moving speed is fast, the silkworm foil is deformed after long-term use. Therefore, during the clamping process, the silkworm foil is easily damaged and the gripping of the silkworm foil is unreliable. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] like Figure 1 and Figure 2 As shown, a telescopic silkworm foil clamping mechanism includes a mounting frame 121 and a clamping unit 100, two clamping units 100 are slidably mounted on the mounting frame 121, and the two clamping units 100 are arranged at an interval. A driving mechanism for driving the two clamping units 100 to move toward or away from each other is also installed on the mounting frame 121. The driving mechanism works to make the two clamping units 100 move toward each other. At this time, the two clamping units 100 clamp the silkworm foil. When the silkworm foil needs to be released, the driving mechanism works in the reverse direction to make the two clamping units 100 move away from each other.

[0030] In this embodiment, if Figure 2As shown, the clamping unit 100 is slidably mounted on the mounting frame 121 through a linear motion pair. The linear motion pair can move the clamping unit 100 in a straight line, thereby ensuring that the clamping unit 100 can better clamp the silkworm foil. The linear motion pair is a prior art. Optionally, the linear motion pair includes a linear guide rail 127 and a slider 128. The linear guide rail 127 is mounted on the mounting frame 121, and the linear guide rail 127 is arranged along the telescopic direction of the clamping unit 100. The guide rail is mounted on the mounting frame 121, and a slide groove is installed on the slider 128. The slider 128 is mounted on the clamping unit 100. On the top, the slide groove slides on the linear slide 127. In the present embodiment, after the silkworm foil is grabbed, it is necessary to move the silkworm foil to a specified position, so the silkworm foil is usually located at the bottom. Therefore, in order to ensure the reliability of the connection between the slider 128 and the linear slide 127, the slide groove is optionally a dovetail groove. Of course, the structure of the linear slide 127 must also be adapted according to the dovetail groove, thereby ensuring the sliding fit between the linear slide 127 and the dovetail groove. Furthermore, in the present embodiment, there are two groups of linear moving pairs, which are arranged at intervals. Through the two groups of linear moving pairs, the straightness of the movement of the clamping unit 100 is further ensured.

[0031] In this embodiment, if Figure 2 As shown, the driving mechanism includes a driving motor 122, a support shaft 123 and a synchronous belt. The support shaft 123 is installed on the mounting frame 121 through a bearing seat. The driving motor 122 is installed on the mounting frame 121, and the power output end of the driving motor 122 is connected to the support shaft 123. At least two driving pulleys are installed on the support shaft 123. Driven pulleys corresponding to the driving pulleys are also installed at both ends of the mounting frame 121. A synchronous belt is wrapped around the driving pulley and the driven pulley. The synchronous belt is connected to the corresponding clamping unit 100. The driving motor 122 works, thereby driving the support shaft 123 to rotate, thereby causing the driving pulley to rotate. After the driving pulley rotates, it drives the synchronous belt to move. When the synchronous belt moves, it drives the clamping unit 100 to move.

[0032] In this embodiment, the clamping unit 100 has a sliding plate 101, a support arm and a clamping mechanism, one end of the support arm is connected to the sliding plate 101, and the other end of the support arm is installed with the clamping mechanism, a clamping groove for clamping the silkworm foil is opened on the clamping mechanism, a slider 128 is installed on the sliding plate 101, a pressing block 126 is installed on the sliding plate 101, and a synchronous belt is connected to the corresponding pressing block 126. Further, as Figure 2As shown, the pressing block 126 includes a pressing plate 131 and a fixing seat 132. The fixing seat 132 is mounted on the mounting frame 121. The pressing plate 131 is mounted on the fixing seat 132, and the pressing plate 131 and the fixing seat 132 clamp the belt body of the corresponding synchronous belt. During installation, the fixing seat 132 is detachably mounted on the mounting frame 121 by a locking screw, and then the synchronous belt is placed on the fixing seat 132, and then the fixing seat 132 and the pressing plate 131 are locked by screws. Through the clamping of the pressing plate 131 and the fixing seat 132, the synchronous belt and the sliding plate 101 move synchronously. In this embodiment, in order to ensure the reliability of the synchronous belt being clamped by the pressing plate 131 and the fixing seat 132, an anti-slip structure is provided on the clamping surface of the fixing seat 132. Optionally, as Figure 4 As shown, the anti-slip structure is a plurality of convex teeth 135 arranged at intervals. The convex teeth of the fixing seat 132 mesh with the convex teeth 135 on the synchronous belt, and the synchronous belt is compressed and cannot slip, thereby ensuring the synchronous movement between the synchronous belt and the sliding plate 101.

[0033] In this embodiment, if Figure 2 and Figure 3As shown, two driving pulleys are installed on the support shaft 123, one of which is equipped with a first synchronous belt 124, and the other is equipped with a second synchronous belt 125. The pressing block 126 clamps the process belt body 133 of the corresponding synchronous belt. In this embodiment, when the mounting frame 121 is placed horizontally, the driving motor 122 is installed on the bottom of the mounting frame 121 through a motor bracket, and the bearing seat is also installed at the bottom of the mounting frame 121, wherein the first synchronous belt 124 is located on the left side of the mounting frame 121, and the second synchronous belt 125 is located on the right side of the mounting frame 121, the belt body on the upper side of the first synchronous belt 124 is the process belt body 133, the belt body on the lower side of the first synchronous belt 124 is the return belt body 134, and the belt body on the lower side of the second synchronous belt 125 is the process belt body 133, and the belt body on the upper side of the second synchronous belt 125 is the return belt body 134, that is, the belt body on the upper side of the first synchronous belt 124 is connected to the pressing block 126, and the The belt body at the lower side of the two synchronous belts 125 is connected to the pressure block 126. When in use, when the driving motor 122 rotates forward, the driving support shaft 123 rotates. At this time, the two pressure blocks 126 move toward each other, thereby driving the two clamping units 100 to move toward each other, thereby shortening the distance between the two clamping units 100, and then clamping the silkworm foil. When the silkworm foil needs to be released, the driving motor 122 rotates in the opposite direction, thereby causing the two clamping units 100 to move back to back, thereby increasing the distance between the two clamping units 100, thereby releasing the silkworm foil. In this embodiment, a position sensor 129 for detecting the position of the sliding plate is installed on the top of the mounting frame 121, and in order to facilitate the position sensor 129 to detect the sliding plate 101, a through hole is opened on the mounting frame 121. During the release process of the silkworm foil, when the position sensor 129 detects the sliding plate 101, it indicates that the sliding plate 101 has returned to the initial position and the release of the silkworm foil is completed.
