Description

Technical Field

[0001] The utility model relates to a device for manufacturing cables, in particular to a mobile vertical cable extruder. Background Art

[0002] A cable is made up of one or more mutually insulated conductors and an outer insulating protective layer, and is a wire for transmitting electricity or information from one place to another. From the definition of a cable, it can be seen that the conductor and the insulating layer are essential components of a cable.

[0003] The insulating layer is generally divided into an inner insulating layer and an outer sheath. The inner insulating layer generally directly wraps the conductor to form a cable core, and the outer sheath generally wraps a plurality of cable cores concentrated together. The material of the insulating layer is generally plastic, and its preparation process is as follows: granular plastic is fed into an extruder, heated and extruded by the extruder to form a molten fluid, the fluid enters the cavity of an extrusion die, wraps the conductor, and forms a firm insulating layer after cooling out of the die.

[0004] Traditional extruders are usually of horizontal structure, that is, the axis of the extrusion screw is horizontally arranged. Horizontal extruders usually have relatively good stability. However, due to the production needs of our company, vertical extruders are currently used in the workshop. The vertical extruder includes a column, a base, a transmission box, a first side plate, a second side plate, a motor mounting seat, a motor, and an extrusion unit. The lower end of the column is connected to the base, the transmission box is installed at the upper end of the main column, the first side plate and the second side plate are located at the upper part of the column and are respectively fixed to the column, the motor mounting seat is fixed to the first side plate, the motor is fixed to the motor mounting seat, the output end of the motor is connected to the input end of the transmission box through a coupling, the output end of the transmission box is connected to the power input end of the extrusion unit. The extrusion unit consists of a housing, an extrusion screw, a heating component, and a bearing. The arrangement direction of the extrusion screw is perpendicular to the horizontal plane, and the remaining assembly relationships are conventional structures and will not be elaborated here.

[0005] When the above-mentioned extruder works, since the extrusion screw will be subjected to a large back pressure, the back pressure is transmitted to the motor through the transmission box and the coupling in sequence, causing the whole motor to have a slight displacement in the opposite direction. The higher the motor speed, the greater the pressure, the slightly larger the displacement distance, and the louder the abnormal noise will be. According to analysis, the main factors for the above situation are as follows: the support point of the transmission box is only the upper end of the column, and since there is a large distance between the output end of the motor and the input end of the transmission box, the output end of the motor is connected to the input end of the transmission box through a coupling, and the back pressure causes the axial direction of the coupling and the rotating shaft of the motor to be deflected. Although the axial deflection amount is not large, after being applied to the bearings inside the motor, the uneven bearing force leads to accelerated wear, thus generating abnormal noise, and the higher the motor speed, the louder the abnormal noise will be. Summary of the Utility Model

[0006] The utility model provides a mobile vertical cable extruder, and the utility model avoids abnormal noises generated by the motor during operation.

[0007] The technical solutions for solving the above technical problems are as follows:

[0008] The mobile vertical cable extruder includes a column, a base, a transmission box, a motor, and an extrusion unit. The lower end of the column is connected to the base. The motor is located on one side of the column, and the extrusion unit is located at the other end of the column. It further includes a top plate. The top plate is fixed to the upper end of the column. The transmission box is entirely located on the top plate and fixed to the top plate. The motor is fixed to the top plate. The torque output end of the motor passes through the top plate and is connected to the input end of the transmission box. The extrusion unit is fixed to the top plate. The torque input end of the extrusion unit passes through the top plate and is connected to the output end of the transmission box.

[0009] Further, it also includes a hanging bracket and a cushion block for supporting the motor. The hanging bracket is fixed to the top plate, and the cushion block is located between the hanging bracket and the motor.

[0010] Further, walking wheels for moving the base are installed at the bottom of the base;

[0011] It also includes a lifting type stabilizing mechanism that cooperates with the column. When the bottom of the lifting type stabilizing mechanism is at the same height position as the walking wheels, the base is in a stable state.

[0012] Further, the lifting type stabilizing mechanism includes a first clamping component, a second clamping component, an annular component, and a stabilizing frame. The annular component is sleeved on the column. The first clamping component is located above the annular component and connected to the column. The second clamping component is located below the annular component and connected to the column. There are multiple stabilizing frames arranged at intervals along the circumferential surface of the annular component.

[0013] Further, both the first clamping component and the second clamping component are nuts. External threads are provided on the circumferential surface of the column. The first clamping component and the second clamping component are respectively connected to the column through threads.

[0014] Further, both the first clamping component and the second clamping component include a sleeve and a pin. A first jack is provided on the sleeve, and a second jack is provided on the column. The pin passes through the first jack on the sleeve and cooperates with the second jack.

[0015] Further, the stabilizing frame includes a bracket and a support foot. The bracket is fixed to the annular component, and the support foot is fixed to the bracket.

[0016] In the present utility model, a first bearing and a second bearing are installed in both the top plate and the box body of the transmission box. The torque output end of the motor passes through the first bearing in the top plate and the transmission box and is fixed to the driving pulley in the belt transmission mechanism. The torque input end of the extrusion unit passes through the second bearing in the top plate and the transmission box and is fixed to the driven pulley in the belt transmission mechanism. This direct connection structure eliminates the intermediate links, improves the overall rigidity of the transmission structure, shortens the transmission distance, reduces the transmission load, enables the torque output by the motor to effectively balance or exceed the back pressure, and thus avoids the motor from generating a small displacement during operation, which may cause accelerated wear of the internal bearings of the motor and generate abnormal noises.

Detailed Description of the Preferred Embodiment

[0022] The present utility model will be further described in detail below with reference to the drawings and the detailed description of the preferred embodiment.

[0023] As Figures 1 to 3 shown, the mobile vertical cable extrusion machine of the present utility model includes a column 1, a base 2, a transmission box 3, a motor 4, an extrusion unit 5, and a top plate 6. The lower end of the column 1 is connected to the base 2. The motor 4 is located on one side of the column 1, and the extrusion unit 5 is located at the other end of the column 1. The top plate 6 is fixed to the upper end of the column 1. The transmission box 3 is integrally located on the top plate 6 and fixed to the top plate 6, so that the transmission box 3 can obtain stable support. The transmission box 3 is composed of a box body and a transmission mechanism installed in the box body. The transmission mechanism can adopt any one of a belt transmission mechanism, a sprocket chain transmission mechanism, and a gear transmission mechanism. In the present utility model, the belt transmission mechanism is preferably adopted for the transmission mechanism.

[0024] The motor 4 is fixed to the top plate 6. The housing of the motor 4 is directly fixed to the top plate 6 by screws. The torque output end of the motor 4 passes through the top plate 6 and is connected to the input end of the transmission box 3. The extrusion unit 5 is fixed to the top plate 6. The torque input end of the extrusion unit 5 passes through the top plate 6 and is connected to the output end of the transmission box 3.

[0025] Both the top plate 6 and the interior of the transmission box 3 are equipped with a first bearing and a second bearing. The torque output end of the motor 4 passes through the first bearing inside the top plate 6 and the transmission box 3 and is fixed to the driving pulley in the belt transmission mechanism. The torque input end of the extrusion unit 5 passes through the second bearing inside the top plate 6 and the transmission box 3 and is fixed to the driven pulley in the belt transmission mechanism. This directly connected structure eliminates the intermediate links, enhances the overall rigidity of the transmission structure, shortens the transmission distance, reduces the transmission load, enables the torque output by the motor to effectively balance or exceed the back pressure, and thus avoids the motor from generating minute displacements during operation, which would otherwise cause accelerated wear of the internal bearings of the motor and produce abnormal noises.

[0026] The mobile vertical cable extruder of the present utility model further includes a hanging bracket 7 and a cushion block 8 for supporting the motor 4. The hanging bracket 7 is fixed to the top plate 6, and the cushion block 8 is located between the hanging bracket 7 and the motor 4. Through the supporting effect formed by the hanging bracket 7 and the cushion block 8 on the motor 4, the motor 4 is prevented from being suspended, thereby increasing the stability of the motor 4.

[0027] Compared with a horizontal extruder, the mobile vertical cable extruder of the present utility model has the advantage of occupying less floor space and is less restricted by site factors during use. Therefore, traveling wheels 9 for moving the base 2 are installed at the bottom of the base 2. The extruder as a whole can be moved to the required working position through the traveling wheels 9.

[0028] Since the extrusion unit 5 is connected to the extrusion die, generally through a pipeline connection, after the traveling wheels 9 are installed, to prevent the extruder from being displaced due to factors such as vibration, and thus avoid the pipeline connecting the extrusion unit 5 and the extrusion die from swinging, which would cause unstable pressure inside the extrusion die. In the present utility model, a lifting type stabilizing mechanism that cooperates with the column 1 is provided on the column 1. When the bottom of the lifting type stabilizing mechanism is at the same height position as the traveling wheels 9, the base 2 is in a stable state.

[0029] When the mobile vertical cable extruder needs to move, the lifting type stabilizing mechanism is retracted to avoid contact with the foundation. When the mobile vertical cable extruder needs to be in a stable state, the lifting type stabilizing mechanism is released to a position where its bottom is at the same height as the traveling wheels 9, that is, both the lifting type stabilizing mechanism and the traveling wheels 9 are supported on the foundation.

[0030] The lifting and stabilizing mechanism includes a first clamping member 10, a second clamping member 11, an annular member 12, and a stabilizing frame. The annular member 12 is sleeved on the column 1. The first clamping member 10 is located above the annular member 12 and connected to the column 1. The second clamping member 11 is located below the annular member 12 and connected to the column 1. There are multiple stabilizing frames arranged at intervals along the circumferential surface of the annular member 12.

[0031] Both the first clamping member 10 and the second clamping member 11 are nuts. External threads are provided on the circumferential surface of the column 1. The first clamping member 10 and the second clamping member 11 are respectively threadedly connected to the column 1. When the lifting and stabilizing mechanism of this structure is adjusted in height, by rotating the first clamping member 10 and the second clamping member 11, the height position of the annular member 12 is adjusted, and then the position of the stabilizing frame is adjusted. For the lifting and stabilizing mechanism of this structure, since the first clamping member 10 and the second clamping member 11 are nuts and clamp the annular member 12, it has the advantage of good stability.

[0032] Both the first clamping member 10 and the second clamping member 11 include a sleeve and a pin. A first jack is provided on the sleeve, and a second jack is provided on the column 1. The pin passes through the first jack on the sleeve and cooperates with the second jack. When the lifting and stabilizing mechanism of this structure is adjusted in height, the pin is pulled out to release the locking between the sleeve and the column 1. After moving the sleeve to the required position, the pin is reinserted into the first jack and the second jack to lock the lifting and stabilizing mechanism on the column. The lifting and stabilizing mechanism of this structure has the advantage of quickly adjusting the height of the stabilizing frame.

[0033] The stabilizing frame includes a bracket 13 and a support foot 14. The bracket 13 is fixed to the annular member 12, and the support foot 14 is fixed to the bracket 13. The bracket 13 of the present utility model can be an L-shaped fixed bracket or a folding bracket. In the present utility model, a folding bracket is preferably used for easy storage.

[0034] The folding rack includes a first connecting frame 13a, a second connecting frame 13b, and a swing rod 13c. One end of the first connecting frame 13a is fixed to the annular member 12, for example, the two are fixed by welding. The other end of the first connecting frame 13a is hinged to one end of the second connecting frame 13b. The other end of the second connecting frame 13b is connected to the support leg 14 by a threaded manner to facilitate fine adjustment of the height of the support leg 14 (each position of the foundation cannot ensure being on the same horizontal plane). One end of the swing rod 13c is hinged to the middle of the second connecting frame 13b. A sliding groove 13d is provided on the first connecting frame 13a. A bolt passes through the other end of the swing rod 13c and is slidably engaged with the sliding groove 13d. When it is necessary to expand the first connecting frame 13a and the second connecting frame 13b into an L shape, loosen the fastening of the swing rod 13c and the first connecting frame 13a by the bolt, rotate the second connecting frame 13b, and the swing rod 13c swings around the hinge portion with the second connecting frame 13b under the drive of the bolt. After reaching the specified position, fasten the swing rod 13c and the first connecting frame 13a with screws.
