Abstract
Description
Technical Field
[0001] The invention relates to the field of silk cocoon processing, in particular to an adaptive clamping device based on a silk cocoon cutting machine. Background Art
[0002] Silkworm cocoons are an important raw material for silk, and the cutting of silkworm cocoons is a key step in the silk processing process. The clamping device in traditional silkworm cocoon cutting equipment still relies on manual operation. The operator manually adjusts the position of the clamp and the tool to clamp the cocoon for cutting. Although this method has certain flexibility, it is inefficient and easily affected by human factors, resulting in damage to the cocoon or uneven cutting, which is difficult to meet the needs of industrial production.
[0003] At present, the clamping device for silk cocoons is not widely used in the cocoon cutting process, mainly due to the special characteristics of silk cocoons. The outer shell of the cocoon is hard, while the inner part is delicate, soft and fragile silk, which needs to maintain appropriate clamping force. At the same time, the cocoons come in different sizes and shapes, and the clamping device needs to adapt to these adaptive changes.
[0004] However, the existing cocoon clamping device design has many limitations: 1. Insufficient cutting accuracy: For cocoons with large length differences, there is a problem of too high or too low cutting points during the cutting process, which will directly affect the effectiveness of cutting and the silk yield. The deviation of the cutting point causes some cocoons to be unable to be fully cut, and the remaining cocoon parts cannot be efficiently utilized, resulting in a waste of raw materials. 2. Poor matching with cutting equipment: The design of the clamping device needs to be coordinated with the overall structure of the cutting equipment to ensure the precise matching between the clamp and the cutting point. If the clamping device is not designed reasonably, the position of the clamp and the motion trajectory of the cutting tool cannot achieve a good fit, which will lead to unstable cutting or clamping errors, thereby affecting the working efficiency and processing quality of the whole machine. 3. Insufficient flexibility and flexibility: Due to the large differences in the shape and size of cocoons, existing clamping devices often lack sufficient flexibility. Many clamps are designed based on fixed size and shape, and cannot be dynamically adjusted according to the characteristics of different cocoons, resulting in poor adaptability to the processing object. In actual production, the morphological differences of cocoons are inevitable. This lack of flexibility increases the difficulty of operation and limits the automation level of the production line.
[0005] Manual operation not only cannot maintain accuracy for a long time, but also has high labor intensity, which greatly restricts the scale and industrialization of cocoon processing. Therefore, how to design an efficient, accurate and flexible clamping device that can adapt to cocoons of different sizes and shapes is a key issue that needs to be solved in the field of cocoon cutting technology. Summary of the invention

DETAILED DESCRIPTION
[0017] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.
[0018] An adaptive clamping device based on a silk cocoon cutting machine is used in the clamping process of silk cocoons of the silk cocoon cutting machine. The device comprises: The main body 1 is a rectangular structure, and a support block 104 is connected to the main body 1. The main body 1 is connected to the transmission device by a key connection or a spline connection, and is driven by a motor to perform circular motion. The specific form of the transmission device can be a chain drive, a gear drive or other suitable transmission methods.
[0019] Guide shaft 101: Two guide shafts 101 are symmetrically arranged on both sides of the main body 1. A spring 102 is installed on the guide shaft 101, and the two ends of the spring 102 are respectively supported on the spring support seat 103 and the shaft sleeve 202 on the clamping plate 201. When installing the guide shaft 101, insert it into the limit hole 107 of the spring support seat 103 on the main body 1 to ensure that each section of the guide shaft 101 has a spring support seat to prevent deformation during operation.
[0020] Clamping component 2: The clamping component 2 is positioned on the main body 1 through the support block 104 and the spring 102. The clamping component 2 includes two left and right clamping plates 201, which realize clamping and loosening along the direction of the guide shaft 101. The clamping plates 201 on both sides form a concave structure for placing the cocoons to be cut. A flexible gasket 203 and an adaptive spring 204 are provided in the groove. The flexible gasket 203 has a conical surface on the inner side of the groove, so that cocoons of different shapes can fit well. The adaptive spring 204 adapts to cocoons of different sizes by deformation, ensuring that the longitudinal dimensions of the protruding part of the cocoon on the clamping plate 201 are roughly consistent, thereby ensuring the consistency of the cutting point.
[0021] Wheel set 205: Wheel set 205 is arranged below the clamping plate 201, and the wheel set 205 is symmetrically distributed on the left and right. The wheel set 205 is installed on the clamping plate 201 through the positioning pin 206 to achieve rolling contact.
[0022] Support plate 3: The support plate 3 is fixed on the frame by bolts, buckles, etc. The support plate 3 is provided with linearly arranged wheel groups 205, and the wheel groups 205 are in rolling contact with each other.
[0023] Working principle: The motor drives the main body 1 to move, and the wheel set 205 under the clamping plate 201 contacts the wheel set 205 on the support plate 3, and relative movement occurs, driving the clamping plate 201 to reciprocate under the action of the roller to achieve clamping and loosening without the need for an additional servo motor drive.
[0024] The clamping plate 201 is slidably connected to the guide shaft 101 through the shaft sleeve 202. The guide shaft 101 passes through the positioning blocks 105 in sequence and is fixedly connected to the outermost positioning block 105. The positioning block 105 has the same structure as the positioning block 105, but is located in a different position, and is used to fix the end of the guide shaft 101. The clamping plate 201 is driven to reciprocate through the relative movement of the wheel set and the compression and extension of the spring 102 on the guide shaft 101.
[0025] In the relaxation stage, the wheel group 205 is in continuous contact with the wheel group 205, so that the clamping plate 201 is fully separated and maintained in a relaxed state until the cocoon placement process is completed and the clamping stage is entered. The relaxation time depends on the speed at which the motor drives the main body 1 to move and the length of the support plate 3. According to the actual time when the cocoon is placed in the groove, the length of the support plate 3 is set to 30 cm.
[0026] The maximum diameter of the groove is designed to be 2.3 cm when it is relaxed, and the diameter is designed to be 1.5 cm after clamping. The overall size of the groove is designed to be 0.8-1.3 times the size of the cocoon to ensure that it can adapt to the cocoon size of different silkworm species. The distance from the elastic washer 203 in the groove to the uppermost edge of the clamping plate 201 is set to 2-2.8 cm. Larger cocoons compress the spring 204 under the elastic washer 203 by their own weight, while smaller cocoons make the deformation of the spring 204 smaller or even unchanged, thereby ensuring that the longitudinal dimensions of the cocoon part protruding from the clamping plate 201 are roughly consistent, ensuring the consistency of the cutting point.
[0027] Six clamping components 2 are arranged on each main body 1 and are symmetrically distributed. The clamping components 2 on both sides of the symmetrical parts are respectively matched with two identical support plates 3 to simplify the parts.
[0028] The working process of the adaptive clamping device is: the clamping plate 201 supports and relaxes - clamps - supports and relaxes again in a cycle. The first stage of support and relaxation is used to place the cocoons, followed by the clamping and cutting stages. After the cutting is completed, the cocoon removal process is immediately carried out, and then support and relax are performed again, the cutting process is ended, and the next cycle begins. The second support and relaxation is directly used as the initial support action of the next cycle, achieving seamless connection between processes and improving efficiency.
[0029] The first stage of the clamping part 2 supporting and relaxing is achieved by moving the main body 1 toward the support plate 3. The wheel group below the clamping plate 201 includes 8 pulleys. During the process of being supported and relaxed by the wheel group 205 on the support plate 3, the difference in the movement of the clamping plate 201 on the guide shafts 101 on both sides is reduced. The wheel group 205 cooperates with each other to reserve a position for the wheel group 205 to slide into. When the clamping part 2 is driven by the motor, the wheel group 205 slides into the reserved position to stretch it open and relax. During the relaxation process, the wheel group 205 on the clamping plate 201 is always in contact with the pulleys on 2-3 support plates 3 to ensure stability during the clamping process.
[0030] The only power device of the whole device is a motor that drives the main body clamping unit 1 to perform circular motion. The motor can be connected to a transmission chain drive through a transmission component arranged on the central limiting hole 107 of the main body 1.
[0031] The support plate 3 is only provided in the support and relaxation stage. After the relaxation stage is completed, the main body 1 leaves the support plate 3 under the drive of the motor, and the clamping part 2 is clamped under the elastic force of the spring 102. The spring 102 is divided into units and installed between the clamping plate 201 and the support block 104, which act independently without interfering with each other, thereby ensuring the stability of each clamping part 2 on the same main body 1.
[0032] After clamping, the motor drives the main body 1 to move smoothly to the cutting point. Since the cocoon placing groove is equipped with an elastic component, the range of the cocoon cutting point can be guaranteed. The cutter does not move during cutting, and the clamping device moves forward at a certain speed to complete the cutting. After the cutting is completed, the clamping device continues to move at the original speed.
[0033] In the cocoon taking link, the clamping part 2 remains in a clamped state. At this time, the clamping part 2 needs to support and relax the cocoon taking, and the working principle is the same as the support and relaxation mode of placing the cocoon, which improves efficiency.
[0034] The support plate 3 can be installed on the horizontal surface of the frame, or it can be turned 180 degrees by a transmission device and installed on the vertical surface of the frame. The installation method is selected according to the actual scene. However, the matching method of the clamping component 2 and the support plate 3 is consistent with the above method.
[0035] After the cocoon is taken out, the main body 1 is driven by the transmission device to the starting position, completing one cycle and smoothly switching to the next cycle.
[0036] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
