Description

Technical Field

[0001] This invention relates to the field of cable production technology, and in particular to a protective device for filling rope operation on a cable-forming machine and a cable production system. Background Technology

[0002] A cabling machine is a type of wire and cable equipment used for cabling and armoring multi-core rubber-sheathed cables, plastic-insulated power cables, cross-linked cables, telephone cables, and control cables of various cross-sections. Depending on the rotational speed, cabling machines can generally be divided into two types: cage-type cabling machines and high-speed cage-type cabling machines. High-speed cage-type cabling machines are used for stranding copper-core aluminum stranded wires and bare aluminum wires, and can also be used for cabling plastic-insulated power cables, rubber-sheathed cables, and other products.

[0003] However, due to limitations in the production process, existing cable-making machines require the intermittent filling of non-metallic strips such as PP ropes during the production process. This process requires manual filling of non-metallic strips, and because the equipment is running at high speed, employees' fingers are constantly at risk of being caught in the equipment, posing a significant mechanical injury safety hazard.

[0004] Therefore, those skilled in the art are dedicated to developing a protective device for cable-making machine filler rope operations and a cable production system that can prevent employees' fingers from being caught in the equipment. Summary of the Invention

[0005] In view of the above-mentioned deficiencies of the prior art, the present invention discloses a cable forming machine filler rope operation protection device and cable production system. The technical problem to be solved is to provide a cable forming machine filler rope operation protection device and cable production system that can prevent employees' fingers from being caught in the equipment.

[0006] To achieve the above objectives, the present invention provides a protective device for cable-making machine filling rope operations, including an insulating cylinder. The insulating cylinder includes an integrally formed cylindrical part and a conical part. A first stepped retaining ring and a second stepped retaining ring are provided on the outside of the connection between the cylindrical part and the conical part. A detachable locking member is sleeved on the free end of the cylindrical part. A metal fixing cylinder is slidably sleeved between the locking member and the second stepped retaining ring. A buffer damping compression spring is provided inside the metal fixing cylinder and between it and the first stepped retaining ring.

[0007] When not triggered, the metal fixing cylinder is in contact with the locking member and both are energized to form a closed circuit; after triggering, the metal fixing cylinder separates from the locking member and the metal fixing cylinder contacts the second stepped retaining ring, and the closed circuit is broken.

[0008] Preferably, the metal fixing cylinder is fixedly connected to the stranding head of the cable forming machine, and the insulating cylinder can slide axially relative to the stranding head.

[0009] Preferably, the insulating cylinder is made of nylon material, but other suitable insulating materials may also be used.

[0010] Preferably, the locking element is a metal locking nut, and the free end of the cylindrical portion has an external thread that mates with the metal locking nut, so that the locking element and the cylindrical portion form a detachable connection. During assembly, the buffer damping spring and the metal fixing sleeve are first installed on the outside of the cylindrical portion, and then the metal locking nut is screwed on the outside of the cylindrical portion.

[0011] Preferably, the outer diameter of the first stepped retaining ring is smaller than the outer diameter of the second stepped retaining ring, so that the buffer damping spring is compressed inside the metal fixed cylinder between the first stepped retaining ring and the metal fixed cylinder, which can slide relative to the insulating cylinder between the locking member and the second stepped retaining ring.

[0012] Preferably, the distance at which the metal fixing cylinder and the locking member can be separated is less than the width of the first stepped retaining ring. This ensures that when the metal fixing cylinder slides relative to the insulating cylinder between the locking member and the second stepped retaining ring, one end of the metal fixing cylinder is always fitted outside the first stepped retaining ring, thus ensuring the smoothness of the relative sliding.

[0013] Preferably, the closed circuit is a 24V safety voltage circuit, and the metal fixing cylinder is provided with a safety voltage terminal.

[0014] Preferably, after the closed loop is broken, the status information is sent to the control center through the electrical control loop. The control center can control the production line to stop quickly to avoid injury to the employees' hands.

[0015] Preferably, the locking member is connected to a signal output terminal to send status information to the control center.

[0016] The present invention also provides a cable production system, including the cable-forming machine filling rope operation protection device as described above.

[0017] The beneficial effects of this invention are:

[0018] After assembly, the protective device of this invention forms a cable-forming machine filling rope operation protection device at the filling rope section of the cable-forming machine. This protective device has a dual protection structure of mechanical travel limit and electrical sensing control. When employees fill non-metallic strips, their hands can only move within a fixed area, namely the conical space inside the conical part and the space outside. Once the safe area is exceeded, the hand touches the conical part, causing the entire insulating cylinder to shift and triggering the first mechanical limit position travel protection. At the same time, once the limit position is reached, the metal fixed cylinder contacts the second stepped retaining ring, and the closed circuit formed by the metal fixed cylinder and the locking member is broken. The status information is sent to the control center through the electrical control circuit, and the production line is quickly stopped. Therefore, the protective device of this invention can provide dual safety protection for employees' hands, preventing employees' fingers from being caught in the equipment.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that in the description of the present invention, terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific manner. Therefore, they should not be construed as limitations on the present invention. Terms such as "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] like Figures 1 to 4As shown, the present invention provides a protective device for filling rope operations on a cable-making machine, including an insulating cylinder 1. The insulating cylinder 1 includes an integrally formed cylindrical portion 13 and a conical portion 14. A first stepped retaining ring 11 and a second stepped retaining ring 12 are provided on the outside of the connection between the cylindrical portion 13 and the conical portion 14. A detachable locking member 2 is fitted on the free end of the cylindrical portion 13. A metal fixing cylinder 3 is slidably fitted between the locking member 2 and the second stepped retaining ring 12. A buffer damping spring 4 is provided inside the metal fixing cylinder 3 between the metal fixing cylinder 3 and the first stepped retaining ring 11. The outer diameter of the first stepped retaining ring 11 is smaller than the outer diameter of the second stepped retaining ring 12, so that the buffer damping spring 4 is compressed inside the metal fixing cylinder 3 between the metal fixing cylinder 3 and the first stepped retaining ring 11. The metal fixing cylinder 3 can slide relative to the insulating cylinder 1 between the locking member 2 and the second stepped retaining ring 12. Meanwhile, the distance at which the metal fixing cylinder 3 and the locking member 2 can separate is less than the width of the first stepped retaining ring 11. This ensures that when the metal fixing cylinder 3 slides relative to the insulating cylinder 1 between the locking member 2 and the second stepped retaining ring 12, one end of the metal fixing cylinder 3 remains outside the first stepped retaining ring 11, thus ensuring smooth relative sliding. The locking member 2 is a metal locking nut, and the free end of the cylindrical part 13 has an external thread that mates with the metal locking nut, allowing the locking member 2 and the cylindrical part 13 to form a detachable connection. The locking member 2 is also connected to a signal output terminal to send status information to the control center. During assembly, first, the buffer damping spring 4 is fitted over the cylindrical part 13, then the metal fixing cylinder 3 is installed over the cylindrical part 13, with the inside of the metal fixing cylinder 3 abutting against the buffer damping spring 4. Finally, the metal locking nut is screwed over the cylindrical part 13 to complete the assembly of this protective device.

[0027] like Figure 1 As shown, when not triggered, the metal fixing cylinder 3 is in contact with the locking element 2, and both are energized, forming a closed circuit; as Figure 2 As shown, upon triggering, the metal fixing cylinder 3 separates from the locking element 2, and the metal fixing cylinder 3 contacts the second stepped retaining ring 12, thus breaking the closed circuit. In practical implementation, to ensure safety, the closed circuit is a 24V safety voltage circuit, and the metal fixing cylinder 3 is equipped with a safety voltage terminal. After the closed circuit is broken, the status information is sent to the control center through the electrical control circuit. The control center can then control the production line to stop quickly, preventing injury to employees' hands.

[0028] In the above embodiments, the protective device of the present invention, after assembly, forms a cable-forming machine filling rope operation protective device at the filling rope section of the cable-forming machine. This protective device has a dual protective structure of mechanical travel limit and electrical sensing control. When employees fill non-metallic strips, their hands can only move within a fixed area, namely the conical space within the conical part 14 and its external space. Once the safe area is exceeded, the hand touches the conical part 14, causing the entire insulating cylinder 1 to shift, triggering the first mechanical limit position travel protection. At the same time, once the limit position is reached, the metal fixed cylinder 3 contacts the second stepped retaining ring 12, and the closed circuit formed by the metal fixed cylinder 3 and the locking member 2 is broken. The status information is sent to the control center through the electrical control circuit, and the production line is quickly stopped. Therefore, the protective device of the present invention can provide dual safety protection for employees' hands, preventing employees' fingers from being caught in the equipment.

[0029] like Figure 5 As shown, in a specific installation method, a metal fixing cylinder 3 can be fixedly connected to the stranding head 5 of the cable-making machine, and the insulating cylinder 1 can slide axially relative to the stranding head 5.

[0030] The present invention also provides a cable production system, including the above-mentioned cable-forming machine filling rope operation protection device.

[0031] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
