Abstract
Description
Technical Field
[0001] This invention relates to the field of silk reeling equipment in silk production engineering, specifically to an automatic silk reeling machine with a flexible connection mechanism that eliminates the need for thread threading. Background Technology
[0002] Silk reeling is the process of extracting silk from silkworm cocoons. The main processes of silk reeling using modern automatic silk reeling machines include threading, thread sorting, thread adding, thread joining, thread gathering, sheath twisting, raw silk winding, and drying.
[0003] like Figure 1 As shown, during silk reeling, the raw silk 9 moves with the winding mechanism. The rotating winding moves upward at a speed v. The thread-gathering process involves combining the threads of several cocoons (one cocoon, one thread) into a single raw silk by passing them through the thread-gathering device's hole (approximately 0.2 mm in diameter). Passing through the thread-gathering device reduces the surface moisture of the raw silk and detects any roughness on the silk. If roughness appears on the raw silk, the thread-gathering device hole will prevent the roughness from passing through, causing the fault lever to rotate around the fulcrum o, simultaneously pulling the linkage of the steel wire 3. The reeling process is stopped by the institution and resumed only after the roughness or other faults are manually eliminated, thus ensuring the cleanliness, purity, and other quality indicators of the raw silk.
[0004] Existing thread-collecting devices all use threaded fasteners to connect to the fault lever of the automatic silk reeling machine during installation. Installation and disassembly require specialized tools and take several minutes to complete. Each automatic silk reeling machine has 400 threads, and each thread is equipped with one thread-collecting device, totaling 400 devices. When changing the reeling specification, a thread-collecting device with the corresponding hole diameter must also be replaced, requiring the disassembly and reassembly of 400 devices. This is a large workload and labor-intensive, thus requiring further solutions. Summary of the Invention
[0005] The purpose of this invention is to overcome the shortcomings in the above-mentioned background technology and provide a flexible connection mechanism for a thread collector that does not require threading. This mechanism should have the characteristics of simple structure, convenient assembly and disassembly, and strong connection.
[0006] The technical solution of this invention is:
[0007] The thread-collecting device without thread-piercing has an elastic connection mechanism, including an insert plate disposed at the front end of the fault lever and an insertion port disposed at the rear end of the thread-collecting device without thread-piercing; the fit between the receiving surface of the insertion port and the receiving surface of the insert plate is an interference fit.
[0008] During installation, the insert plate is inserted into the socket using a press-in method. The stress caused by the elastic deformation generated by the interference fit makes the enclosing surface press against the enclosed surface, thus achieving a fixed connection. Conversely, disassembly is completed by performing the reverse operation.
[0009] The shape of the socket is suitable for the shape of the plugboard; the socket is provided with a positioning boss, and the plugboard is provided with a positioning hole matched with the positioning boss; when the plugboard is inserted into the socket, the positioning boss is embedded into the positioning hole, and the socket clamps the plugboard through elastic deformation, and the plugboard and the socket form an interference fit.
[0010] The thickness of the plugboard is greater than the socket gap.
[0011] The positioning boss is a circular truncated cone, the top surface diameter of the positioning boss is smaller than the hole diameter of the positioning hole, and the bottom surface diameter of the positioning boss is greater than the hole diameter of the positioning hole.
[0012] The socket comprises a socket hole for containing the plugboard and clamping plates extending rearward from both sides of the socket hole and used for clamping the plugboard; the positioning boss is arranged on the inner side of one of the clamping plates; the socket gap is the distance from the top surface of the positioning boss to the other clamping plate; the distance between the clamping plates is smaller than the thickness of the plugboard; when the plugboard is inserted into the socket, the positioning boss is partially embedded into the positioning hole, and the clamping plates clamp the plugboard through elastic deformation.
[0013] A guide inclined surface is arranged between the clamping plates for guiding the plugboard to be inserted into the socket hole.
[0014] The positioning hole is arranged on the second plugboard, or the positioning hole is arranged on the third plugboard, or the positioning hole is arranged between the second plugboard and the third plugboard.
[0015] The plugboard comprises, in sequence from front to back, a first plugboard, a second plugboard and a third plugboard.
[0016] The width of the first plugboard is smaller than the width of the third plugboard, and the width of the second plugboard gradually increases from front to back.
[0017] The beneficial effects of the present application are:
[0018] 1. The elastic connection mechanism of the non-wearing accumulator provided by the present application can make the non-wearing accumulator installed on the fault lever of the automatic silk reeling machine without special tools, and the installation or disassembly can be completed manually in only 1-2 seconds, thereby saving labor and time, being convenient to operate, and being reliable in connection.
[0019] 2. When silk gum or the like blocks the accumulator hole during the silk reeling of the non-wearing accumulator, the non-wearing accumulator can be quickly disassembled for cleaning treatment, thereby avoiding affecting normal production.
[0020] 3. When different specifications of raw silk are reeled, different non-wearing accumulators with different accumulator hole diameters are selected, and 400 non-wearing accumulators of each automatic silk reeling machine can be quickly replaced, thereby greatly improving the work efficiency.

DETAILED DESCRIPTION
[0032] In order to make the purpose, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.
[0033] As shown in Figure 1 , the no-wearing gatherer elastic connection mechanism includes an insertion plate arranged on the failure lever 1 and an insertion hole arranged on the no-wearing gatherer 2 and matched with the insertion plate. The no-wearing gatherer is connected with the failure lever through the connection mechanism to form an interference fit.
[0034] The plug plate is inserted into the socket by press-in method during installation: the inner wall of the socket as the containing surface and the outer wall of the plug plate as the contained surface, when the fault lever is connected with the non-wearing collector, the fit between the containing surface and the contained surface is interference fit, that is, the stress of the elastic deformation caused by the interference amount makes the containing surface bear the contained surface, so as to realize the connection and fixation. Conversely, the disassembly is completed by reverse operation. The plug plate is arranged at the front end of the fault lever, Figure 1 and Figure 6 the right side of the fault lever is the front end of the fault lever, Figure 1 and Figure 6 the left side of the fault lever is the rear end of the fault lever. The socket is arranged at the rear end of the non-wearing collector, Figure 1 and Figure 3 the left side of the non-wearing collector is the rear end of the non-wearing collector, Figure 1 and Figure 3 the right side of the non-wearing collector is the front end of the non-wearing collector, and the non-wearing collector hole 2-2 is arranged at the front end of the non-wearing collector.
[0035] As shown in Figure 6 , the plug plate includes a first plug plate 1.1, a second plug plate 1.2 and a third plug plate 1.3 from front to back (from right to left in the figure).
[0036] The first plug plate and the third plug plate are rectangular, and the second plug plate is a right-angled trapezoid. The width of the first plug plate is smaller than the width of the third plug plate, and the width of the second plug plate gradually increases from front to back (the distance in the vertical direction in Figure 6 ), and the bottom edge of the second plug plate is arranged obliquely 1.2.1, the top of the first plug plate, the second plug plate and the third plug plate are flush, and the plug plate thickness b (the distance in the horizontal direction) is equal everywhere. Figure 7
[0037] The plug plate thickness b is greater than the socket gap a, so that the socket can be elastically deformed when the plug plate is inserted into the socket. The plug plate thickness is generally 1.3 mm, and the socket gap is set according to the need, slightly smaller than the plug plate thickness, generally 1.0-1.2 mm.
[0038] The plug plate is provided with a positioning hole 1-1. The positioning hole is located in the second plug plate, or the positioning hole is located in the third plug plate, or the positioning hole is located between the second plug plate and the third plug plate (as shown in Figure 6 ). The diameter of the positioning hole is 3.5 mm.
[0039] The shape of the socket is suitable for the shape of the plug plate. The socket includes a socket hole 2.1, a clamping plate 2.2 and a guide inclined surface 2.3.
[0040] The opening of the socket hole faces the left side of the fault lever, Figure 3 , and two parallel clamping plates are arranged on both sides of the socket hole and extend backward, and the inner side of one of the clamping plates is provided with a positioning boss 2-1 matched with the positioning hole.
[0041] The clamping plate spacing B is smaller than the thickness b of the plug, and the plug can squeeze the clamping plate when inserted into the socket, and the width of the socket is equal to the clamping plate spacing.
[0042] The positioning boss is a circular truncated cone, the top surface diameter of the positioning boss is smaller than the hole diameter of the positioning hole, and the bottom surface diameter of the positioning boss is larger than the hole diameter of the positioning hole. The socket gap a is the spacing between the top surface of the positioning boss and the other clamping plate. When the plug is inserted, the plug can make the clamping plate elastically deform by extruding the circular truncated positioning boss. Figure 4 and Figure 5 It is shown that the height of the positioning boss is half of the socket gap.
[0043] The clamping plate spacing B is smaller than the thickness b of the plug, and the plug can squeeze the clamping plate when inserted into the socket, and the width of the socket is equal to the clamping plate spacing.
[0044] When the plug is completely inserted into the socket, the positioning boss is partially embedded in the positioning hole. Since the thickness of the plug is larger than the socket gap, the clamping plate still remains in an open state, and the socket and the plug form an interference fit. The clamping plate clamps the plug by elastic deformation, and at the same time, the first plug is completely inserted into the socket, so that the free-entry collector cannot rotate around the positioning boss, and the free-entry collector is connected with the fault lever.
[0045] The working principle of the present application is as follows:
[0046] 1. The free-entry collector elastic connection mechanism provided by the present application can complete the installation and disassembly of the free-entry collector by hand operation, and the time consumption is only 1-2 seconds.
[0047] 2. When the free-entry collector is installed on the fault lever through the free-entry collector elastic connection mechanism, the interference fit between the plug and the socket makes the free-entry collector connected with the fault lever.
[0048] 3. When installing, the plug is inserted into the socket by pressing in, and the guide slope can guide the first plug to be accurately inserted into the socket (the socket completely contains the first plug). When the plug is inserted, the plug first extrudes the positioning boss to slightly open the clamping plate. After the plug is inserted in place, the positioning boss is partially embedded in the positioning hole (since the bottom surface diameter of the positioning boss is larger than the hole diameter of the positioning hole, the positioning boss cannot completely enter the positioning hole). The clamping plate still remains in an open state, so that the clamping plate clamps the plug by using the elastic deformation stress generated by the interference amount, so that the free-entry collector is connected with the fault lever. Conversely, reverse operation can make the positioning boss slide out of the positioning hole, and the disassembly of the free-entry collector is completed.
[0049] The above embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
