Description

Technical Field

[0001] This utility model belongs to the field of factory-scale silkworm rearing equipment, and specifically relates to a spin dryer for silkworm rearing equipment. 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, without the need for air drying or tumble drying, resulting in high drying efficiency and good effect. However, the structure of existing spin-drying equipment is not suitable for spin-drying silkworm rearing equipment. It is incompatible with the equipment and cannot limit and fix the equipment, resulting in poor spin-drying stability and problems such as displacement and misalignment, which affect the spin-drying effect. Utility Model Content

[0004] The purpose of this utility model is to provide a spin dryer for silkworm rearing equipment. In view of the defects in the prior art, a limiting structure is set for the spin dryer. This limiting structure can limit and fix the silkworm rearing equipment, so as to keep it stable during the centrifugal spin drying process and improve the spin drying effect.

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

[0006] A spin dryer for silkworm rearing includes a spin dryer mechanism and a drive mechanism for driving the spin dryer mechanism. The spin dryer mechanism includes a rotating drum and a limiting structure. The rotating drum is connected to the drive mechanism, which drives the rotating drum to rotate. The rotating drum is used to drive the equipment to spin dry centrifugally. The limiting structure is installed on the rotating drum and is used to limit the equipment within the rotating drum.

[0007] Furthermore, the drum is equipped with a through hole, which is used to drain the water generated by centrifugal drying downwards.

[0008] Furthermore, the limiting structure includes a plate and frame mounting connector, which encloses and forms a spin-drying station, which is used to place appliances.

[0009] Furthermore, the plate and frame mounting assembly includes a base plate and three limiting components installed on the base plate. The three limiting components form a spin-drying station, which confines the appliance within the spin-drying station.

[0010] Furthermore, the limiting structure includes a movable limiting member, which moves above the appliance under the action of centrifugal force and presses against the appliance to limit the appliance.

[0011] Furthermore, the movable limiting component includes a movable pressure plate and a hinge bolt. The movable pressure plate is hinged by the hinge bolt. Under the action of centrifugal force, the movable pressure plate rotates to the top of the appliance and presses down on the appliance, thus limiting the appliance.

[0012] Furthermore, the movable limiting component also includes a limiting bolt. The movable pressure plate is provided with a movable limiting hole, and the limiting bolt passes through the movable limiting hole and is fixed. The limiting bolt and the movable limiting hole are used to control the rotation amplitude of the movable pressure plate.

[0013] Furthermore, the movable limiting component also includes a buffer, which acts on the movable pressure plate for cushioning.

[0014] Furthermore, the buffer includes a buffer cylinder and a buffer top rod. The buffer top rod is connected to the buffer cylinder and is retractable. The buffer top rod acts on the movable pressure plate for buffering.

[0015] Furthermore, the drive mechanism includes a spin-drying motor, a drive pulley, a driven pulley, a belt, and a main shaft. The spin-drying motor is connected to the drive pulley, the drive pulley and the driven pulley are connected by a belt for transmission, and the driven pulley is connected to the spin-drying mechanism through the main shaft.

[0016] Furthermore, the spin dryer also includes a housing assembly with a drain outlet for draining water.

[0017] Furthermore, the spin dryer also includes a positioning component, which is used to position the spin-dried drum back to the position it was in before spin-drying.

[0018] Furthermore, the positioning component includes a cylinder and a positioning pin. The drum is provided with a positioning hole. The cylinder is connected to the positioning pin through a piston rod. The positioning pin and the positioning hole are matched with each other. By inserting the positioning pin into the positioning hole, the drum after spin-drying is positioned to the position before spin-drying.

[0019] Furthermore, the positioning component also includes a proximity switch and a position positioning element. The proximity switch and the position positioning element are matched with each other. The proximity switch is used to identify whether the drum has rotated to the position before spin-drying, thereby controlling the cylinder according to the identification signal.

[0020] The above technical solution has the following beneficial effects:

[0021] This utility model provides a limiting structure for a spin dryer. This limiting structure can limit and fix the silkworm rearing equipment, keeping it stable during the centrifugal spin drying process, improving the spin drying effect, avoiding problems such as equipment displacement or misalignment during the spin drying process, and improving the spin drying efficiency.

[0022] The plate and frame assembly forms a spin-drying station, which can confine the silkworm rearing equipment within the spin-drying station, preventing problems such as horizontal displacement or misalignment, and ensuring horizontal stability. The spin-drying station can hold stacked equipment groups, achieving the purpose of spin-drying multiple equipment simultaneously, significantly improving spin-drying efficiency.

[0023] The movable limiting component rotates under the action of centrifugal force, and its movable pressure plate rotates into the spin-drying station, thereby pressing down on the equipment in the spin-drying station from the top to ensure vertical stability; at the same time, it tightly combines the equipment with the drum to improve the spin-drying effect.

[0032] The present invention aims to provide a spin dryer for silkworm rearing equipment, which is equipped with a limiting structure. This limiting structure can limit and fix the silkworm rearing equipment, so as to keep it stable during the centrifugal spin drying process, improve the spin drying effect, avoid problems such as equipment displacement or misalignment during the spin drying process, and improve the spin drying efficiency.

[0033] The technical solution of this utility model will be described in detail below with reference to specific embodiments:

[0034] like Figure 1 As shown, a spin dryer for silkworm rearing includes a housing assembly, a spin-drying mechanism, and a drive mechanism for driving the spin-drying mechanism. The housing assembly includes a flat plate 11, support legs 12, an upper outer shell 13, a lower outer shell 14, and an inner liner 16. The flat plate 11 and support legs 12 provide support to ensure the stability of the spin dryer. The bottom of the support legs 12 is equipped with vibration-absorbing rubber and shock-absorbing pads, which greatly reduces the friction generated by spin-drying and improves the stability of spin-drying. The upper outer shell 13 and the lower outer shell 14 are sealed together by a sealing gasket 15. The upper outer shell 13 protects the spin-drying mechanism, allowing the spin-drying operation to be carried out internally. This prevents water from splashing out and also prevents the equipment from being thrown out due to malfunction, improving safety. An opening slightly larger than the size of the equipment is provided at the top of the upper outer shell 13 for placing the equipment into the spin dryer. The lower outer shell 14 is connected to the upper outer shell 13. The water spun out falls into the lower outer shell 14. The lower outer shell 14 is mounted on the flat plate 11 and has a drain outlet that passes through the flat plate 11. The water spun out is discharged through the drain outlet. The inner liner 16 encloses the spin-drying mechanism, which protects the spin-drying structure and prevents the water from splashing out, allowing the water to fall downwards.

[0035] like Figure 2As shown, the spin-drying mechanism is driven to rotate by a drive mechanism, and spins the equipment by centrifugal rotation. The equipment can be a silkworm frame, partition, or cocoon cage, etc. The spin-drying mechanism includes a rotating drum 2 and a limiting structure. The rotating drum 2 is connected to the drive mechanism, and the equipment to be spin-dried is placed on it to drive the equipment to rotate, thereby achieving the purpose of centrifugal spin-drying. The rotating drum 2 has a disc structure with multiple through holes 21, through which the water generated during spin-drying falls downward.

[0036] like Figure 2 As shown, to ensure that the appliance can rotate stably with the drum 2, a limiting structure is set for the drum 2. This limiting structure is used to limit and fix the appliance to be spun to the drum 2. The limiting structure includes a plate and frame mounting connector 3 and a movable limiting component 4. The plate and frame mounting connector 3 limits the appliance in the horizontal direction. It includes a base plate 34 and limiting components 31, 32, and 33 installed on the base plate 34. The base plate 34 is set on both sides of the drum 2. Each base plate 34 is equipped with limiting components 31, 32, and 33. Limiting component 31 is composed of two vertical rods and an upper horizontal rod connected together. Limiting component 31 is installed on the base plate 34 one in front and one behind. Limiting component 32 is composed of two vertical plates and is used to connect limiting component 31 and limiting component 33. Limiting component 33 is composed of two vertical rods and an upper horizontal rod connected together. The limiting components 31, 32, and 33 on each base plate 34 combine to form a concave limiting part. The limiting parts on the left and right sides cooperate to form a spin-drying station 35 with a limiting function. The spin-drying station 35 limits the horizontal movement of the equipment, preventing the equipment from deviating or becoming misaligned in the horizontal direction, and ensuring horizontal stability. The spin-drying station 35 can hold stacked equipment groups, achieving the purpose of spin-drying multiple equipment at the same time, significantly improving the spin-drying efficiency.

[0037] like Figure 3As shown, the movable limiting member 4 is a vertical limiting device, and four of them are installed, respectively on the transverse rods of the four limiting members 31. The movable limiting member 4 includes an assembly plate 47 and a movable pressure plate 41, a hinge bolt 42, and a limiting bolt 43 installed on the assembly plate 47. The top of each of the four limiting members 31 is equipped with an assembly plate 47. The movable pressure plate 41 is L-shaped and has a hinge hole and a movable limiting hole 44. The hinge bolt 42 passes through the hinge hole and the assembly plate 47 and is connected to the limiting member 31. In the vertical rod cavity of 1, the limiting bolt 43 passes through the movable limiting hole 44 and the assembly plate 47 and is fixed to the horizontal rod of the limiting member 31. Under the action of the hinge bolt 42, the movable pressure plate 41 can rotate with the hinge bolt 42 as the axis. During centrifugal drying, the movable pressure plate 41 rotates due to centrifugal force, and its front end rotates into the drying station 35, thereby pressing down the appliance in the drying station 35, ensuring vertical stability, and limiting and fixing it in the drying station 35. At the same time, it tightly connects the appliance with the drum 2, improving the drying effect.

[0038] The movable limiting hole 44 is an elongated arc-shaped hole, the length of which is determined according to actual requirements. This movable limiting hole 44 matches the movement direction of the movable pressure plate 41. The rotation amplitude of the movable pressure plate 41 is limited by the fixed limiting bolt 43, allowing the movable pressure plate 41 to rotate to the designed position under centrifugal force. In this position, the movable pressure plate 41 can firmly press down on the appliance, preventing excessive rotation and loss of its pressing effect. Both the hinge bolt 42 and the limiting bolt 43 are connected to the anti-loosening safety plate 46 and secured with nuts to prevent loosening of the hinge bolt 42 and the limiting bolt 43.

[0039] The movable limiting component 4 also includes a buffer 45, which is mounted on the assembly plate 47 and acts on the movable pressure plate 41 for cushioning. This buffer 45 is a hydraulic buffer 45, comprising a buffer cylinder 451 and a buffer push rod 452. The buffer push rod 452 is connected to the buffer cylinder 451 and is extendable. The buffer push rod 452 acts on the rear end of the movable pressure plate 41. During centrifugal drying, the movable pressure plate 41 rotates under centrifugal force. At this time, the buffer push rod 452 retracts into the buffer cylinder 451 under force. After centrifugal drying, the buffer push rod 452 extends and resets under hydraulic pressure, thereby pushing the rear end of the movable pressure plate 41 to reset it and release the pressure on the appliance. The ingenious structural design achieves automatic clamping and automatic reset.

[0040] like Figure 4As shown, the drive mechanism includes a spin-drying motor 61, a drive pulley 62, a driven pulley 64, a belt 63, and a main shaft 65. The spin-drying motor 61 is installed in the motor housing 17 of the flat plate 11. Its motor shaft is connected downward to the drive pulley 62. The drive pulley 62 and the driven pulley 64 are connected and driven by the belt 63. The driven pulley 64 is connected upward to the drum 2 through the main shaft 65. A bearing assembly 66 is connected to the outside of the main shaft 65 to improve stability.

[0041] like Figure 5 and Figure 6 As shown, the spin dryer also includes a positioning component 5, which is used to position the spin-dried drum 2 to the position before spin drying. The positioning component 5 includes a cylinder 51 and a positioning pin 54. The cylinder 51 is mounted on the lower housing 14 via a cylinder mounting component, which includes two cylinder mounting plates 52 and a positioning rod 53 connecting the cylinder mounting plates 52. The cylinder 51 is connected to the positioning pin 54 via the piston rod, which can drive the positioning pin 54 to extend and retract. The drum 2 is provided with a positioning hole 22, and the positioning pin 54 matches the positioning hole 22, that is, the positioning pin 54 can be inserted into the positioning hole 22. The cylinder mounting plate 52 is also connected to a pin sleeve 55, which is used to install the positioning pin 54 and plays a guiding role. After the spin-drying is completed, the drum 2 gradually decelerates. When the positioning hole 2 rotates to the position before spin-drying before the drum 2 stops, the cylinder 51 is activated to control the positioning pin 54 to be inserted into the positioning hole 22, thereby positioning the drum 2 in the position before spin-drying, so that the spin-drying device can be accurately placed in the spin-drying station 35.

[0042] To identify whether the drum 2 has rotated to the position before spin-drying, the positioning assembly 5 also includes a proximity switch 7 and a position positioning element 71. The position positioning element 71 is located on the driven pulley 64, and the proximity switch 7 is below the plate 11, at the same height as the position positioning element 71, and facing the position positioning element 71. During the positioning process, the position positioning element 71 rotates to the position of the proximity switch 7. The proximity switch 7 senses the proximity signal and transmits the signal to the corresponding controller. After receiving the proximity signal, the controller controls the cylinder 51 to start, driving the positioning pin 54 to insert into the positioning hole 22, thereby achieving positioning. The proximity switch 7 is connected to a proximity switch adjustment rod 72, which can adjust the proximity switch 7.

[0043] The positioning component 5 is provided in two sets, which can improve the accuracy of positioning.

[0044] 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.
