Description

Technical Field

[0001] This utility model relates to the field of automatic silk reeling machine technology, specifically to a stepless cocoon feeding transmission control device. Background Technology

[0002] During automatic silk reeling, the cocoons are pulled by the silk braids to the automatic cocoon feeding mechanism. The user needs to select the appropriate cocoon feeding hopper based on the cocoon capacity of the feeding machine. The feeding system selects a feeding constant, typically with three selectable settings: 0, 1, and 2. 0: Small hopper; 1: Large hopper; 2: Large hopper when both signals are valid; Small hopper when only one signal is valid. Therefore, the signal from the automatic sensing mechanism indicating the amount of cocoons in the feeding machine is used to implement stepped adjustment control via two feeding hoppers, allowing for no cocoons, fewer cocoons, or more cocoons added. The feeding rate refers to the probability that the automatic silk reeling machine successfully adds a cocoon within the feeding cycle after the fineness sensor sends a feeding signal during the silk reeling process.

[0003] For example, a patent entitled "Laser Automatic Measurement Device," application number 201720914156X, discloses a laser automatic measurement device, relating to the field of automatic silk reeling machine technology. It includes a cocoon feeder and a circular running track for the feeder. A laser irradiator is positioned above the circular running track, and a laser irradiator controller is fixed to the outer side of the running track. This laser irradiator controller is electrically connected to the automatic silk reeling machine control cabinet. The laser irradiator, positioned above the circular running track, is used to detect the number of remaining cocoons in the cocoon box of the feeder passing under the scanner, thereby achieving accurate measurement. Utility Model Content

[0004] Technical problem to be solved by the utility model

[0005] The technical problem to be solved by this utility model is to provide a stepless cocoon feeding transmission control device. The cocoon feeding amount control method can realize stepless adjustment, so that the cocoon amount in the cocoon feeding machine is in an ideal state, improve the feeding rate, meet the needs of silk reeling production, and further improve the automation level of the silk reeling machine.

[0006] Technical solution

[0007] To solve the above problems, the technical solution provided by this utility model is as follows:

[0008] A stepless cocoon feeding transmission control device includes a fixed bracket, a motor mounted on the bracket, a gear at the output end of the motor meshing with a rack, the rack being fixed to a baffle, a lifting bucket being attached to one side of the baffle, an opening being formed between the bucket opening of the lifting bucket and the baffle, the baffle moving steplessly along the direction parallel to the opening, and the motor being connected to a controller and connected to an automatic measuring mechanism through the controller.

[0009] Support frame: As the basic support structure of the entire device, it ensures that other components can be installed stably and operate normally.

[0010] Motor: It rotates precisely at a certain angle according to the instructions issued by the controller, thereby driving the gears to rotate. The characteristics of the motor are that it can achieve precise positioning and stepless adjustment.

[0011] Gear and rack: The gear connected to the motor output end meshes with the rack fixed to the baffle. When the motor rotates, it drives the gear to rotate, which in turn causes the rack to move in a straight line, thus realizing the stepless movement of the baffle.

[0012] Baffle: A lifting bucket is fitted onto the baffle, and the baffle can move steplessly along the direction parallel to the opening. The movement of the baffle directly affects the size of the lifting bucket opening, thereby achieving stepless adjustment of the cocoon loading rate.

[0013] Lifting bucket: Used for the actual loading and unloading of cocoons. The size of the opening formed between the lifting bucket and the baffle determines the number of cocoons added to the cocoon feeder each time.

[0014] Controller and automatic measuring mechanism: The controller is responsible for receiving information from the automatic measuring mechanism (such as the remaining amount of cocoons in the cocoon machine) and controlling the motor's operation accordingly to adjust the position of the baffle and achieve precise control of the amount of cocoons added.

[0015] Optionally, the lifting bucket is provided with a left guide cocoon plate and a right guide cocoon plate on both sides.

[0016] The left and right guide cocoon plates can effectively guide the cocoons into the lifting bucket accurately, reducing the possibility of deviation or scattering of cocoons during the transportation process, and ensuring that the number of cocoons added each time meets the expectations.

[0017] Optionally, the other side of the baffle is provided with a cocoon opening.

[0018] The cocoon-adding opening is located on the other side of the baffle, which can be used as another entrance for adding cocoons.

[0019] Optionally, a guide rail seat is fixedly connected to the bracket, and a guide rail is installed on the other side of the baffle. The guide rail seat is provided with a sliding groove that engages with the guide rail.

[0020] Guide rail base: Fixed to the bracket, providing a stable frame for the entire moving system. It not only bears the weight of the baffle and its related components but also guides the baffle's precise linear movement via its grooves. Guide rail: Mounted on the other side of the baffle and engages with the grooves on the guide rail base. The guide rail design allows the baffle to move smoothly and stably along the set track, ensuring accurate and reliable adjustments each time. Groove: Located on the guide rail base, engaging and sliding with the guide rail. This design ensures that the baffle can move steplessly along a preset path under motor drive, while reducing friction and improving the system's response speed and positioning accuracy. The design of the guide rail and groove increases the stability of the baffle's movement, reduces errors that may be caused by vibration or other external forces, and helps maintain long-term stable operation of the equipment.

[0021] Alternatively, the groove can be a circular groove, wherein the circumference of the circular arc of the cross-section of the circular groove is greater than half.

[0022] The groove is circular: the cross-section of the groove on the guide rail seat is a portion of a circle (arc shape), not a rectangular or V-shaped conventional sliding guide rail. The circumference of the arc is greater than half: this means the opening width of the groove is smaller than the diameter of the circle, and its containment angle is greater than 180° (e.g., approximately 240°~270°). This gives the guide rail excellent containment and guiding properties within the groove. Because the arc length exceeds half a circle, the guide rail is partially contained within the groove, effectively preventing it from detaching even in high-speed or high-vibration working environments, greatly enhancing the stability and resistance to eccentric loads during baffle movement. Traditional linear guide rails have weak resistance to lateral forces, while the circular groove structure, due to its large containment angle, can better withstand lateral forces from all directions, making the baffle less prone to swaying or jamming during movement.

[0023] Optionally, the side of the lifting bucket is provided with a fixing plate, which is fixed to the end of the telescopic column.

[0024] The fixing plate is set on the side of the lifting bucket, and its main function is to serve as a connection point to connect the lifting bucket to the telescopic column.

[0025] The design of the fixed plate ensures a secure and reliable connection between the lifting bucket and the telescopic column, while also facilitating installation, disassembly, and maintenance. The telescopic column is a length-adjustable mechanical component, typically composed of multiple sleeve sections, capable of extending or shortening as needed. In this device, the telescopic column provides the lifting bucket with vertical position adjustment capability, allowing for flexible adjustment of the bucket's height according to actual requirements. The end of the telescopic column connects to the fixed plate, meaning that the height of the lifting bucket can be changed by adjusting the telescopic column, thus adapting to different cocoon-feeding requirements or equipment layouts.

[0026] Optionally, the lifting bucket is fitted inside the base and the two are slidably engaged.

[0027] The lifting bucket is designed to fit inside the base, and the two are connected by a sliding fit, which enhances the adaptability of the device and allows it to be flexibly adjusted according to different production needs, thereby improving the versatility and practicality of the equipment.

[0028] Optionally, the top of the lifting bucket is provided with an inclined structure, and the inclined structure has multiple vertically parallel through slots.

[0029] The presence of the channel allows the cocoons to be separated one by one as they flow in from the top, preventing them from tangling or piling up.

[0030] Each slot can accommodate one cocoon and guides it to fall vertically, achieving orderly cocoon feeding and improving the success rate of adding cocoons. Because cocoons are irregularly shaped, they are prone to jamming or stacking in traditional planar structures. The inclined surface combined with the vertical slot design effectively reduces frictional resistance between cocoons, allowing them to enter the feeding port smoothly and preventing blockages. Through the dual action of the inclined surface and the slot, the number of cocoons added each time is accurately controllable, facilitating closed-loop control of the stepless cocoon feeding system. Especially in high-frequency cocoon feeding operations, this structure can maintain a stable feeding rhythm and improve overall production efficiency.

[0031] Beneficial effects

[0032] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0033] The technical solution provided by this utility model achieves precise control of the cocoon feeding amount through the design of a motor, gear and rack structure, and adjustable baffle, ensuring that the cocoon quantity in the cocoon feeding machine is maintained at an ideal level, improving the silk-feeding rate while meeting the needs of silk reeling production. Furthermore, its use in conjunction with an automatic measuring mechanism further enhances the automation level and adaptability of the entire system. Attached Figure Description

Detailed Implementation

[0042] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0043] Example 1

[0044] Combined with appendix Figure 1-7 A continuously variable transmission control device for cocoon feeding includes a fixed bracket 2, as shown in the attached figure. Figure 5 The bracket 2 is equipped with a motor 1, which is a stepper motor or a servo motor. The motor 1 is connected to a controller and is connected to the automatic measuring mechanism through the controller.

[0045] The output end of motor 1 is equipped with a gear 3, which meshes with a rack 4. The rack 4 is fixed to a baffle 5. One side of the baffle 5 is fitted with a lifting bucket 8, forming an opening between the bucket opening of the lifting bucket 8 and the baffle 5. The baffle 5 can move steplessly along the parallel direction of the opening. The other side of the baffle 5 is equipped with a feed opening 11, as shown in the attached figure. Figure 2-4 .

[0046] Combined with appendix Figure 6 A guide rail 6 is fixedly connected to the bracket 2, and a guide rail 6 is installed on the other side of the baffle 5. The guide rail 6 seat has a sliding groove 701 that engages and slides with the guide rail 6. The sliding groove 701 is a circular groove, and the circumference of the arc of the cross-section of the circular groove is greater than half. The rack 4 drives the baffle 5 and the guide rail 6 to move linearly back and forth within the guide rail 6 seat. The baffle 5 is located in front of the lifting bucket 8, and when the lifting bucket 8 rises to add cocoons, it can block the cocoons 13 from falling.

[0047] Based on the signal from the automatic sensing mechanism, the program controls the reciprocating motion of motor 1, maintaining an appropriate displacement to ensure that the baffle 5 and the lifting bucket 8 have a suitable opening distance, thus ensuring that the cocoons 13 are added to the cocoon feeding machine. The width of the opening is infinitely adjustable between 10 and 210 mm, achieving appropriate and controllable cocoon feeding amount 13.

[0048] Combined with appendix Figure 3 The lifting bucket 8 has a left guide cocoon plate 9 and a right guide cocoon plate 10 on both sides. The left guide cocoon plate 9 and the right guide cocoon plate 10 are inclined surfaces, forming an open structure. There are multiple cocoons 13 between the left guide cocoon plate 9 and the right guide cocoon plate 10, which form a silk braid 12 through the baffle 5.

[0049] An independent lifting bucket 8 replaces the original two buckets of different sizes. The side of the lifting bucket 8 is provided with a fixing plate 16, which is fixed to the end of the telescopic column 15. The lifting bucket 8 is fitted into the base 17 and the two are slidably engaged.

[0050] Combined with appendix Figure 7 The top of the lifting bucket 8 is equipped with a sloping structure 801, which has multiple vertically parallel through slots 802. Based on signals from the automatic sensing mechanism, the lifting bucket 8 is controlled by a program to make the baffle 5 move in a regular reciprocating linear motion. Based on real-time detection and balanced control of cocoon quantity, the transmission is precise, maintaining a suitable opening distance between the lifting bucket 8 and the cocoon feeder, facilitating the addition of an appropriate amount of healthy cocoons 13 into the cocoon feeder box. The reciprocating stroke is infinitely adjustable, controlling the amount of healthy cocoons 13 added to maintain an ideal cocoon quantity in the feeder, improving the cocoon addition rate, meeting the needs of silk reeling production, and further enhancing the automation level of the silk reeling machine.

[0051] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
