Description

Technical Field

[0001] This utility model belongs to the field of factory-scale silkworm rearing equipment, and specifically relates to a positioning component of a silkworm rearing equipment spin dryer. Background Technology

[0002] Traditional silkworm rearing methods are small-scale, family-run operations. This entirely manual method involves manual labor from egg to adult stage to cocoon harvesting, which is time-consuming, labor-intensive, and inefficient. Furthermore, it is limited by seasonal conditions, allowing silkworms to be raised only at specific times, resulting in extremely low annual cocoon production that cannot meet modern societal demands and has been gradually phased out. To address the shortcomings of traditional small-scale silkworm rearing, large-scale, factory-style silkworm rearing techniques have emerged. To meet the requirements of large-scale farming, rearing equipment such as silkworm frames and carriers have been designed. This equipment enables silkworm rearing, transfer of silkworms between different age groups, and feed delivery, playing a crucial role in factory-style silkworm rearing. After rearing, feed, silkworm excrement, and other impurities remain on the equipment, and their surfaces are teeming with bacteria. Thorough cleaning and disinfection are necessary before reuse; therefore, factory-style silkworm rearing often requires dedicated cleaning equipment or lines.

[0003] Spin-drying equipment is one of the important cleaning devices in factory-scale silkworm rearing. After cleaning, the equipment can be quickly put into use after being spin-dried, eliminating the need for air drying or tumble drying, resulting in high drying efficiency and good effect. A spin-dryer suitable for silkworm rearing equipment has been designed, taking into account its structural characteristics and spin-drying requirements. It uses a mechanical gripping structure to move stacked silkworm rearing equipment into the spin-dryer, spin-dries it, and then moves it out, achieving continuous automated spin-drying operations and improving efficiency. However, in actual use, it was found that the spin-dryer cannot automatically return to its pre-spin-drying position after spin-drying. This makes it difficult for the mechanical gripping structure to move the silkworm rearing equipment out and then feed it in, affecting the continuous spin-drying operation. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning component for a silkworm rearing spin dryer. In view of the defects in the prior art, a positioning component is set for the spin dryer. The positioning component includes a positioning pin and a cylinder for controlling the positioning pin. After the spin dryer spins, it gradually decelerates. When it decelerates to a low speed, the positioning pin is inserted into the positioning hole, thereby resetting the drum of the spin dryer to the position before spin drying, realizing precise feeding and discharging, and realizing continuous spin drying operation.

[0005] To solve the above technical problems, the following technical solution is adopted:

[0006] A positioning component for a silkworm rearing spin dryer is characterized by comprising a cylinder and a positioning pin. The cylinder is connected to the positioning pin and controls the positioning pin to be inserted into the positioning hole of the spin dryer drum, thereby positioning the spin-dried drum to the position before spin drying.

[0007] Furthermore, the positioning component also includes a cylinder mounting component, through which the cylinder is mounted on the spin dryer.

[0008] Furthermore, the cylinder mounting component includes a cylinder mounting plate and a positioning rod, with the cylinder mounting plates connected to each other via the positioning rod.

[0009] Furthermore, the cylinder mounting component also includes a pin sleeve, which is used to install and guide the positioning pin.

[0010] Furthermore, the cylinder mounting component also includes an inner mounting plate.

[0011] Furthermore, the positioning component also includes a proximity switch assembly, which is used to identify whether the drum has rotated to the pre-spinning position, thereby controlling the cylinder according to the identification signal.

[0012] Furthermore, the proximity switch assembly includes a proximity switch and a position positioning element. The proximity switch and the position positioning element are matched with each other. The position positioning element rotates with the drum. The proximity switch is used to identify the position positioning element, thereby identifying whether the drum has rotated to the position before spin-drying.

[0013] Furthermore, the proximity switch is mounted via a proximity switch adjusting rod, which is used to adjust the proximity switch.

[0014] Furthermore, the proximity switch adjusting rod is provided with a connection hole, and the proximity switch is threaded to the connection hole.

[0015] The above technical solution has the following beneficial effects:

[0016] This utility model is a positioning component installed in a spin dryer. The positioning component includes a positioning pin and a cylinder for controlling the positioning pin. After the spin dryer spins dry, it gradually decelerates. When it decelerates to a low speed, the positioning pin is inserted into the positioning hole, thereby resetting the drum of the spin dryer to the position before spin drying, realizing precise feeding and discharging, and realizing continuous spin drying operation.

[0017] The proximity switch assembly serves an identification function, ensuring that the positioning pin is accurately inserted into the positioning socket under the control of the cylinder. Specifically, during the positioning process, the positioning component rotates to the position of the proximity switch. The proximity switch senses the proximity signal and transmits it to the corresponding controller. Upon receiving the proximity signal, the controller activates the cylinder, causing the positioning pin to insert into the positioning socket of the rotating drum, thereby achieving positioning.

Detailed Implementation

[0025] This utility model aims to provide a positioning component for a silkworm rearing equipment spin dryer. The positioning component includes a positioning pin and a cylinder for controlling the positioning pin. After the spin dryer spins, it gradually decelerates. When it decelerates to a lower speed, the positioning pin is inserted into the positioning hole, thereby resetting the drum of the spin dryer to the position before spin drying, achieving precise feeding and discharging, and realizing continuous spin drying operation.

[0026] The technical solution of this utility model will be described in detail below with reference to specific embodiments:

[0027] The positioning component 2 of this utility model is applied to the spin dryer 1 of a silkworm rearing device. The structure of the spin dryer 1 is as follows: Figure 1 As shown, the spin dryer 1 is equipped with a spin drying mechanism, which is as follows: Figure 2As shown, it includes a rotating drum 3 at the bottom and a limiting structure 4 connected to the rotating drum 3. The rotating drum 3 is used to drive the silkworm rearing equipment placed on it to rotate and spin dry. The limiting structure 4 is used to limit the movement of the silkworm rearing equipment, so that it is stably placed on the rotating drum 3 and rotates with the rotating drum 3. During feeding, the mechanical gripping structure grabs the stacked silkworm rearing equipment and puts it onto the rotating drum 3. The limiting structure 4 limits the silkworm rearing equipment. During discharging, the mechanical gripping structure grabs the stacked silkworm rearing equipment and sends it out. In order to achieve precise gripping of the equipment for feeding and discharging by the mechanical gripping structure, the rotating drum 3 needs to be positioned so that the rotating drum 3 is positioned at the designed feeding and discharging position before and after spin drying. Therefore, this utility model designs the positioning component 2.

[0028] Positioning assembly 2 is used to position the spin-dried drum 3 to the position before spin-drying. Positioning assembly 2 includes a cylinder 21 and a positioning pin 25. The cylinder 21 is mounted on the outer shell of the spin dryer 1 via a cylinder mounting component. The cylinder mounting component includes a front cylinder mounting plate 22, a rear cylinder mounting plate 24, a positioning rod 23, a pin sleeve 26, and an inner mounting plate 27. The front cylinder mounting plate 22 and the rear cylinder mounting plate 24 are connected and fixed to each other via the positioning rod 23. The cylinder 21 is mounted on the front cylinder mounting plate 22. The front end of the pin sleeve 26 is fixed to the rear cylinder mounting plate 24, and the rear end is fixed to the inner mounting plate 27. The piston rod of the cylinder 21 is connected to the positioning pin 25, which is connected to and passes through the pin sleeve 26. The drum 3 has a positioning hole 31 at a designed position. This positioning hole 31 matches the positioning pin 25, allowing the positioning pin 25 to be inserted into the positioning hole 31, thereby preventing the drum 3 from rotating and positioning it at the designed inlet / outlet position. After the spin-drying is completed, the drum 3 gradually decelerates. Just before it stops, when the positioning hole 31 rotates with the drum 3 to the position before spin-drying, the cylinder 21 is activated, controlling the positioning pin 25 to be inserted into the positioning hole 31, thereby positioning the drum 32 at the position before spin-drying, so that the spin-drying device can be accurately placed in the spin-drying station.

[0029] The front cylinder mounting plate 22 and the rear cylinder mounting plate 24 are used to fix the cylinder 21 to the housing of the spin dryer 1, and the pin sleeve 26 is used to guide and install the positioning pin 25 so that it can extend and retract linearly.

[0030] To identify whether the drum 3 has rotated to the position before spin-drying, the positioning assembly 2 also includes a proximity switch assembly 5. The proximity switch assembly 5 includes a proximity switch 51 and a position positioning element 52. The position positioning element 52 is mounted on the drive mechanism of the spin dryer 1 and rotates synchronously with the drum 3. The proximity switch 51 is fixedly mounted at the same height as the position positioning element 52 and faces it. During positioning, the position positioning element 52 rotates to the position of the proximity switch 51. The proximity switch 51 senses the proximity signal and transmits it to the corresponding controller. Upon receiving the proximity signal, the controller activates the cylinder 21, causing the positioning pin 25 to insert into the positioning hole 31, thus achieving positioning. The proximity switch 51 is connected to a proximity switch adjusting rod 53. The proximity switch adjusting rod 53 has a screw hole, and the surface of the proximity switch 51 has threads, allowing the proximity switch 51 to be threadedly connected to the proximity switch adjusting rod 53. Rotation can adjust the extension length of the proximity switch 51, thereby adjusting the distance between the proximity switch 51 and the position positioning element 52. Based on the actual positioning effect, multiple positioning components 2 can be set on the spin dryer 1 to improve the positioning accuracy.

[0031] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
