Description

Technical Field

[0001] The present invention belongs to the technical field of cable processing, and particularly relates to a length measuring device for a wire and cable extruder. Background Art

[0002] Cable extrusion length measurement refers to the process in the production of wire and cable, where plastic raw materials are heated and melted by an extruder and then extruded through a die to form a cable, and the length of the cable is recorded during this process. However, such devices can only calculate the overall length of the cable. During use, manual measurement is still required, and then the required size is cut out, which is rather cumbersome. Now, a structure that can leave a length mark on the cable during the length measurement process is proposed. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the present invention provides a length measuring device for a wire and cable extruder, which solves the above problems.

[0007] Further technical solution: The limit frame is slidably connected to a sliding rod. The sliding rod is fixedly connected to the frame. A spring is sleeved on the shaft. One end of the spring is fixedly connected to the limit frame, and the other end of the spring is fixedly connected to the sliding sleeve, so that the limit frame can provide a margin for the sliding of bevel gear A during its sliding process, thereby increasing the meshing time of bevel gear A and bevel gear B.

The bevel gear B is fixedly connected to the meter wheel. The meter wheel is rotatably connected to the frame. An auxiliary wheel is arranged below the meter wheel. The meter wheel and the auxiliary wheel cooperate with each other to tightly press the cable.

[0009] Further technical solution: The auxiliary wheel is rotatably connected to the frame. A bevel gear C is fixedly connected to the auxiliary wheel. The bevel gear C is meshed and connected with the bevel gear D. A reciprocating lead screw is fixedly connected to the axis center of the bevel gear D.

The reciprocating lead screw is threadedly connected to the limit frame to enable the periodic meshing of the bevel gear A and the bevel gear B.

[0010] Further technical solution: The pulling assembly includes a connecting frame, a positioning cylinder, a limiting rod, and a guiding cylinder. The connecting frame is fixedly connected to the frame. The positioning cylinder is fixedly connected to the connecting frame. The positioning cylinder is coaxial with the ring sleeve.

[0013] Beneficial effects

[0014] The present invention provides a meter counting device for a wire and cable extruder, and has the following beneficial effects compared with the prior art:

[0015] 1. When starting to pull the cable, since the meter wheel and the auxiliary wheel cooperate to tightly press against the cable, at this time the cable can drive the meter wheel and the auxiliary wheel to rotate. Thus, the number of rotations of the meter wheel can represent the length of the cable in meters. At the same time, when the auxiliary wheel starts to rotate, the bevel gear C fixedly connected thereto rotates synchronously. Then, at this time, the bevel gear D starts to rotate uniformly under the cooperation of the bevel gear C engaged with it, and the reciprocating screw rod fixedly connected to its axis starts to rotate. As a result, the limit frame threadedly connected to the reciprocating screw rod starts to slide upward along its connection with the slide rod, thereby pushing the bevel gear A gradually closer to the bevel gear B. At the same time, when the insertion block is inserted into the one-way open chute of the insertion sleeve, the bevel gear A starts to mesh with the bevel gear B. At the same time, the insertion sleeve can limit the insertion block to prevent it from continuing to slide upward. At this time, the auxiliary wheel and the meter wheel rotate synchronously, so as to achieve keeping the bevel gear A and the bevel gear B meshed for a period of time when the gears continue to rotate. At this time, the bevel gear B fixedly connected to the meter wheel rotates synchronously with the meter wheel, so that the bevel gear A starts to rotate uniformly under the cooperation of the bevel gear B engaged with it. Furthermore, the guide rod fixedly connected to its axis starts to rotate uniformly around its connection with the limit frame, and the insertion block fixedly connected thereto rotates synchronously. At this time, since the insertion block is inserted into the insertion sleeve, the shaft can start to rotate synchronously with the guide rod, so that the gear fixedly connected to its top rotates uniformly. Then, at this time, the gear ring starts to rotate synchronously under the cooperation of the gear engaged with it, and drives the sleeve fixedly connected to it to rotate uniformly. Then, the multiple laser nozzles fixedly connected to the sleeve start to rotate, so as to periodically stamp out circular rings on the cable to mark the length of the cable. Thus, when the meter wheel rotates a certain number of quantitative turns, that is, when the extruded length of the cable reaches the set value, the laser nozzles rotate simultaneously and leave length marks on the cable through the multiple sleeves fixedly connected thereto;

[0016] 2. After the user pulls out the cable from the gear ring and the auxiliary wheel, passes it through the positioning cylinder and the guiding cylinder in sequence, and attaches one end of it to any rod, at this time the user can start the motor connected to the connecting plate, thereby driving the multiple rods fixedly connected thereto to rotate uniformly, and then start to pull the cable attached thereto, so as to wind the cable around the rod. At this time, since the meter wheel and the auxiliary wheel press tightly against the cable, the cable can drive the meter wheel and the auxiliary wheel to rotate synchronously. At the same time, when the connecting plate rotates, the pulley A fixedly connected thereto rotates synchronously, and the pulley A starts to rotate synchronously with the pulley under the cooperation of the belt drivingly connected to it. At this time, the reciprocating screw rod A fixedly connected to the axis of the pulley starts to rotate, and drives the slider threadedly connected thereto. Then, at this time, the guiding cylinder starts to perform linear reciprocating motion along the length direction of the limiting rod, so that when the cable is wound around the rod, it can provide guidance for the cable, enabling it to be evenly wound thereon.

Detailed implementation manners

[0024] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] The following describes in detail the specific implementation of the present invention with reference to specific embodiments.

[0026] Please refer to Figure 1 、 Figure 2 and Figure 3 , which are provided for an embodiment of the present invention, a length measuring device for a wire and cable extruder, including a frame 101, and further including:

[0027] An identification component 2 for marking the length of the cable;

[0028] The identification component 2 includes a collar 201, a laser nozzle 202, a gear ring 203, a gear 204, a shaft 205, a socket 206 and a plug 207. The collar 201 is rotatably connected to the frame 101. Multiple laser nozzles 202 are symmetrically and fixedly connected inside the collar 201. The gear ring 203 is fixedly connected to the collar 201. One end of the shaft 205 is fixedly connected to the center of the gear 204, and the other end of the shaft 205 is fixedly connected to the socket 206. The socket 206 is inserted with the plug 207. During the sliding process of the plug 207, it can be inserted into the one-way opening chute of the socket 206. The frame 101 is connected to the pulling component 4.

[0029] Please refer to Figure 3 , specifically, the plug 207 is fixedly connected to the guide rod 208. The guide rod 208 is rotatably connected to the sliding sleeve 2003. A damping rubber ring is provided at the connection between the guide rod 208 and the sliding sleeve 2003. The sliding sleeve 2003 is slidably connected to the shaft 2002. The shaft 2002 is fixedly connected to the limit frame 209.

[0030] Please refer to Figure 3 and Figure 4 , specifically, the limit frame 209 is slidably connected to the sliding rod 2001. The sliding rod 2001 is fixedly connected to the frame 101. A spring 2004 is sleeved on the shaft 2002. One end of the spring 2004 is fixedly connected to the limit frame 209, and the other end of the spring 2004 is fixedly connected to the sliding sleeve 2003. Thus, during the sliding process of the limit frame 209, a margin can be provided for the sliding of the bevel gear A 301, thereby increasing the meshing time between the bevel gear A 301 and the bevel gear B 302. The limit frame 209 is connected to the transmission component 3.

[0031] Principle: When the plug 207 is blocked by the socket 206 and stops rising, at this time, since the meter wheel 303 and the auxiliary wheel 304 continue to rotate, the limit frame 209 continues to rise under the cooperation of the reciprocating lead screw 307 threadedly connected thereto. Then, at this time, the relative movement between the sliding sleeve 2003 and the shaft 2002 can be used to avoid interfering with the upward sliding of the limit frame 209. At the same time, the sliding sleeve 2003 starts to compress the spring 2004 fixedly connected thereto, so that the spring 2004 provides a force to enable the plug 207 to tightly press against the socket 206, thereby preventing the bevel gear A 301 from disengaging from the bevel gear B 302 and causing the bevel gear A 301 to be unable to be effectively driven to rotate.

[0032] Please refer to Figure 3 Figure 4 and Figure 6, specifically, the transmission assembly 3 includes a bevel gear A301, a bevel gear B302, a meter wheel 303, and an auxiliary wheel 304. The bevel gear A301 is fixedly connected to the guide rod 208. The bevel gear B302 meshes with the bevel gear A301 during the sliding process of the bevel gear A301, so as to realize the periodic rotation of the sleeve 201 through the periodic meshing of the bevel gear A301 and the bevel gear B302. The bevel gear B302 is fixedly connected to the meter wheel 303. The meter wheel 303 is rotatably connected to the frame 101. An auxiliary wheel 304 is provided below the meter wheel 303. The meter wheel 303 and the auxiliary wheel 304 cooperate with each other to tightly press the cable.

[0033] Please refer to Figure 3 Figure 4 and Figure 6 , specifically, the auxiliary wheel 304 is rotatably connected to the frame 101. A bevel gear C305 is fixedly connected to the auxiliary wheel 304. The bevel gear C305 is meshed and connected with a bevel gear D306. A reciprocating lead screw 307 is fixedly connected to the axis of the bevel gear D306. The reciprocating lead screw 307 is rotatably connected to the frame 101. The reciprocating lead screw 307 is threadedly connected to the limit frame 209 to enable the periodic meshing of the bevel gear A301 and the bevel gear B302.

[0034] In an embodiment of the present invention, when starting to pull the cable, since the meter wheel 303 and the auxiliary wheel 304 cooperate with each other to tightly press the cable, at this time, the cable can drive the meter wheel 303 and the auxiliary wheel 304 to rotate. Thus, the number of rotation turns of the meter wheel 303 can represent the meter number of the cable. At the same time, when the auxiliary wheel 304 starts to rotate, the bevel gear C305 fixedly connected thereto rotates synchronously. Then, at this time, the bevel gear D306 starts to rotate uniformly under the cooperation of the bevel gear C305 meshed with it, and the reciprocating lead screw 307 fixedly connected to its axis starts to rotate. As a result, the limiting frame 209 threadedly connected to the reciprocating lead screw 307 starts to slide upward along its connection with the slide bar 2001, thereby pushing the bevel gear A301 gradually closer to the bevel gear B302. At the same time, when the insertion block 207 is inserted into the one-way open chute of the insertion sleeve 206, the bevel gear A301 starts to mesh with the bevel gear B302. At the same time, the insertion sleeve 206 can form a limit on the insertion block 207 to block its continuous upward sliding. At this time, the auxiliary wheel 304 and the meter wheel 303 rotate synchronously, so as to achieve keeping the bevel gear A301 and the bevel gear B302 meshed and connected for a period of time while the gear 204 continues to rotate. At this time, the bevel gear B302 fixedly connected to the meter wheel 303 rotates synchronously with the meter wheel 303. Thus, the bevel gear A301 starts to rotate uniformly under the cooperation of the bevel gear B302 meshed with it, and further, the guide rod 208 fixedly connected to its axis starts to rotate uniformly around its connection with the limiting frame 209, and the insertion block 207 fixedly connected thereto rotates synchronously. At this time, since the insertion block 207 is inserted into the insertion sleeve 206, the shaft 205 can start to rotate synchronously with the guide rod 208, so that the gear 204 fixedly connected to its top rotates uniformly. Then, at this time, the gear ring 203 starts to rotate synchronously under the cooperation of the gear 204 meshed with it, and drives the sleeve 201 fixedly connected thereto to rotate uniformly. Then, at this time, the plurality of laser nozzles 202 fixedly connected to the sleeve 201 start to rotate, so as to periodically stamp out circular rings on the cable to mark the length of the cable. Thus, when the meter wheel 303 rotates a certain number of quantitative turns, that is, when the extruded meter number of the cable reaches the set value, the laser nozzles 202 rotate simultaneously and leave length marks on the cable through the plurality of sleeves 201 fixedly connected thereto.

[0035] Please refer to Figure 2 and Figure 6 Specifically, the pulling assembly 4 includes a connecting frame 401, a positioning cylinder 402, a limiting rod 403, and a guiding cylinder 404. The connecting frame 401 is fixedly connected to the frame 101. The positioning cylinder 402 is fixedly connected to the connecting frame 401. The positioning cylinder 402 is coaxial with the sleeve 201. The limiting rod 403 is fixedly connected to the frame 101. The central axis of the guiding cylinder 404 is on the same horizontal line as the positioning cylinder 402.

[0036] Please refer to Figure 4, specifically, sliding blocks 405 are symmetrically and fixedly connected to the upper and lower sides of the guiding cylinder 404. Any one of the sliding blocks 405 is slidably connected to the limiting rod 403. The limiting rod 403 is fixedly connected to the connecting frame 401. The other sliding block 405 is threadedly connected to the reciprocating lead screw A406. The reciprocating lead screw A406 is rotatably connected to the connecting frame 401.

[0037] Please refer to Figure 5 and Figure 6 , specifically, one end of the reciprocating lead screw A406 is fixedly connected to a pulley 407. A belt 408 is drivingly connected to the pulley 407. The other end of the belt 408 is drivingly connected to a pulley A409. A connecting disk 4001 is fixedly connected to the center of the pulley A409. A plurality of rods 4002 are symmetrically and fixedly connected to the connecting disk 4001. The other ends of the rods 4002 are detachably and fixedly connected to a fastening disk 4003.

[0038] In the embodiment of the present invention, after the user pulls out the cable from the gear ring 203 and the auxiliary wheel 304, passes it through the positioning cylinder 402 and the guiding cylinder 404 in sequence, and attaches one end of it to any one of the rods 4002. At this time, the user can start the motor connected to the connecting disk 4001, thereby driving the plurality of rods 4002 fixedly connected thereto to rotate uniformly, and then start pulling the cable attached thereto, so as to wind the cable around the rod 4002. At this time, since the meter wheel 303 abuts against the cable with the auxiliary wheel 304, the cable can drive the meter wheel 303 and the auxiliary wheel 304 to rotate synchronously. At the same time, when the connecting disk 4001 rotates, the pulley A409 fixedly connected thereto starts to rotate synchronously, and the pulley A409 starts to rotate synchronously with the pulley 407 under the cooperation of the belt 408 drivingly connected thereto. At this time, the reciprocating lead screw A406 fixedly connected to the center of the pulley 407 starts to rotate, and drives the sliding block 405 threadedly connected thereto. Then, at this time, the guiding cylinder 404 starts to perform a linear reciprocating motion along the length direction of the limiting rod 403, so that when the cable is wound around the rod 4002, it can provide guidance for the cable, enabling it to be evenly wound thereon.

[0039] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0040] The fixed connection referred to in this application means a connection where parts or components are fixed without any relative movement. It is divided into two types: detachable connection and non-detachable connection.

[0041] (1) Detachable connection: Use screws, splines, wedge pins, etc. to fix components together. This connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, wedge pins), and they must be tightened properly.

[0042] (2) Non-detachable connection: mainly refers to welding, riveting, and mortise and tenon fitting, etc. Since it requires forging, sawing, or oxy-fuel cutting to disassemble during maintenance or replacement, the spare parts generally cannot be used a second time. At the same time, during connection, attention should be paid to process quality, technical inspection, and remedial measures (such as calibration, polishing, etc.).

[0043] The sliding connection referred to in this application means that a component can slide along a linear trajectory, and the articulated connection referred to in this application means that a component can rotate along an axial constraint.

[0044] In some cases, the sliding connection and the articulated connection referred to in this application can also be damped, so that the component has the ability to maintain at the desired position.

[0045] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
