Description

Technical Field

[0001] This utility model belongs to the field of cable hot pressing technology, specifically relating to a cable hot pressing printing device and a cable production line. Background Technology

[0002] In cable sheath production, most cable products require clear and durable printing of continuous markings such as the manufacturer's name, product model, and rated voltage on their surface. Currently, ink printing and hot-press printing are the two main processes used.

[0003] Hot stamping is achieved by a concave stamping wheel installed between the extruder head and the cooling water tank. While the outer sheath is still hot after extrusion molding, raised text such as product model and specifications, production date, manufacturer name, and order number are stamped onto the cable surface according to customer requirements.

[0004] Currently, different printing wheels are usually selected for different cable specifications. However, although the design of the printing wheel is adjusted according to the cable specifications, its weight and embossing effect are greatly affected by the cable material and production temperature. In actual use, it is impossible to achieve precise adjustment. A printing wheel that is too light can easily lead to unclear printing, or a printing wheel that is too heavy can easily cause the sheath to be squeezed and deformed, reducing the roundness of the product and directly affecting the surface quality of the cable.

[0005] Therefore, to meet the printing requirements of high-voltage cables, it is urgent to improve existing printing technology or optimize printing devices. Utility Model Content

[0006] To address the shortcomings of existing technologies, a cable hot-press printing device and cable production line are provided to solve the problem of poor printing effect in cable hot-press equipment.

[0007] On the one hand, the technical solution of this utility model to solve the above-mentioned technical problems is as follows: a cable hot-press printing device, comprising:

[0008] Rotating component, with a rotatable connection in its middle;

[0009] A pressure roller assembly is connected to the first end of the rotating member, and the pressure roller assembly is used to contact the surface of the extruded cable;

[0010] An adjustment component, connected to the second end of the rotating member, is used to provide a force for clockwise or counterclockwise rotation about the central rotation center of the rotating member.

[0011] Compared with existing technologies, the above technical solutions have the following beneficial effects:

[0012] The pressure roller assembly contacts the cable and is used to heat-press the cable surface to form text. The rotating part acts like a lever, and the adjustment component mainly provides pulling or pushing force to drive the rotating part to rotate, which in turn causes the pressure roller assembly to adhere to the cable. Clockwise and counterclockwise rotation can adjust the pressure on the cable surface. By controlling the force of the adjustment component through a lever-like principle, the pressure of the pressure roller assembly on the cable surface can be precisely adjusted without the need for frequent replacement of the printing roller.

[0013] Based on the above technical solution, the embodiments of this application can be further improved as follows:

[0014] In one embodiment, the rotating component includes a rotating shaft and two arms connected to the rotating shaft, with the distal ends of the two arms respectively connected to the pressure roller assembly and the adjustment assembly.

[0015] In one embodiment, the extension line from the contact point between the pressure roller assembly and the cable to the rotation center of the rotating member is not perpendicular to the direction of the cable's core line.

[0016] By controlling the contact angle between the pressure roller assembly and the cable, the pressure roller assembly can press obliquely onto the cable. When the rotating part rotates, it can apply a certain force to press the cable, which facilitates the adjustment of the pressure applied to the cable.

[0017] In one embodiment, the pressure roller assembly is located above the cable and below the adjustment assembly.

[0018] By placing the pressure roller assembly above the cable, it is convenient to use the weight of the pressure roller assembly to press down on the cable, reducing the load on the adjustment assembly.

[0019] In one embodiment, the pressure roller assembly includes:

[0020] A wheel frame is connected to the first end of the rotating component;

[0021] A pressure roller, which is rotatably connected to the wheel frame via its axle;

[0022] Two adjusting bolts are screwed onto the wheel frame, and the ends of the adjusting bolts are rotatably connected to the wheel axle of the pressure wheel.

[0023] The pressure roller is connected to the roller frame by adjusting the bolt. The translation position of the pressure roller is adjusted by controlling the screw length of the adjusting bolt. Since the cable is not in a fixed position during the pre-production process, it will move up, down and left and right. Therefore, the setting of the adjusting bolt can adjust the movement of the pressure roller in the left and right direction, so that the pressure roller can press the cable in the middle before production.

[0024] In one embodiment, a fastening nut for securing the adjusting bolt to the wheel frame is also screwed onto the adjusting bolt.

[0025] In one embodiment, the adjustment component includes:

[0026] The adjusting rod, the middle part of which is connected to the second end of the rotating component;

[0027] The weight block is slidably connected to the adjusting rod.

[0028] The downward pressure is adjusted by using the adjustment rod and the weight block. After the weight block is fixed at different positions on the adjustment rod, the lever formed by the rotating component drives the pressure roller assembly to rotate clockwise or counterclockwise around the rotating component, thereby adjusting the pressure on the cable.

[0029] In one embodiment, a fastener is screwed onto the weight block, and the fastener passes through the weight block and abuts against the adjusting rod.

[0030] In one embodiment, the cable hot pressing printing device is provided with at least one limiting seat, which is used to install an air pipe facing the circumference of the pressure roller.

[0031] On the other hand, this embodiment also discloses a cable production line, which includes a printing device as described above, the printing device being disposed between the extruder head and the cooling device of the cable production line. Attached Figure Description

[0045] Example 1

[0046] like Figure 1-2 As shown, the cable hot pressing printing device provided by this utility model includes: a rotating part 1, a pressure roller assembly 2, and an adjusting assembly 3.

[0047] The rotating part 1 is rotatably connected in the middle. Specifically, the printing device is set between the extruder head and the cooling tank to heat-press the newly extruded cable. The rotating part 1 is fixed between the extruder and the cooling tank by bearings and the like.

[0048] The pressure roller assembly 2 is connected to the first end of the rotating member 1 and is used to contact the surface of the extruded cable; the adjustment assembly 3 is connected to the second end of the rotating member 1 and is used to provide a force for clockwise or counterclockwise rotation around the center of rotation of the rotating member 1, using the rotating member 1 to form a lever, while the pressure roller assembly 2 and the adjustment assembly 3 are located at the two ends of the lever respectively.

[0049] Specifically, the pressure roller assembly 2 contacts the cable and is used to heat-press text onto the cable surface. The adjustment assembly 3 mainly provides tension or thrust to drive the rotating part 1 to rotate, thereby causing the pressure roller assembly 2 to adhere to the cable. Clockwise and counterclockwise rotation can adjust the pressure on the cable surface. By controlling the force of the adjustment assembly 3 through a lever-like principle, the pressure of the pressure roller assembly 2 on the cable surface can be precisely adjusted, preventing problems with the printing effect due to the pressure roller 202 being too heavy or too light. Adjusting the weight block 302 in the adjustment assembly 3 avoids frequent replacement of the pressure roller 202. This results in clearer printing on the cable surface and prevents cable deformation and reduced roundness due to excessive weight of the printing roller.

[0050] Specifically, the rotating component 1 includes a rotating shaft 101 and two arms 102 connected to the rotating shaft 101. The rotating shaft 101 is fixed between the extruder head and the cooling tank through a bearing seat. The ends of the two arms 102 are connected to the outer circumferential surface of the rotating shaft 101. The far ends of the two arms 102 are respectively connected to the pressure roller assembly 2 and the adjustment assembly 3. When the rotating component 1 rotates around the rotating shaft 101, it can drive the pressure roller assembly 2 to rotate synchronously.

[0051] To control the deformation of the pressure roller assembly 2 when it presses on the cable, the extension line from the contact point between the pressure roller assembly 2 and the cable to the rotation center of the rotating component 1 is not perpendicular to the axis of the cable. In other words, when the pressure roller assembly 2 rotates with the rotating component 1, the circular outer contour formed is tangent to the cable surface, and the contact point between the pressure roller assembly 2 and the cable coincides with this tangent point. Only this contact point of the pressure roller assembly 2 contacts the cable. To avoid this situation and ensure that the pressure roller assembly 2 can press down on the cable during rotation, the extension line from the contact point between the pressure roller assembly 2 and the cable to the rotation center of the rotating component 1 is controlled to not be perpendicular to the axis of the cable. By controlling the contact angle between the pressure roller assembly 2 and the cable, the pressure roller assembly 2 can press obliquely on the cable. When the rotating component 1 rotates, it can drive the pressure roller assembly 2 to apply a certain force to the cable, which facilitates the adjustment of the pressure applied to the cable.

[0052] To ensure convenient adjustment of the adjustment component 3, the pressure roller assembly 2 is located above the cable and below the adjustment component 3. At the same time, the pressure roller assembly 2 is positioned above the cable, which allows the weight of the pressure roller assembly 2 to press down on the cable, reducing the load on the adjustment component 3.

[0053] The adjustment component 3 is located on the upper part of the pressure roller assembly 2, which can avoid interference with the cable and the pressure roller assembly 2 and facilitate adjustment and control.

[0054] In this embodiment, the pressure roller assembly 2 includes a roller frame 201 and a pressure roller 202. The pressure roller 202 is connected and fixed to the support arm 102 through the roller frame 201. In order to ensure the roundness of the cable during the pressing process, the peripheral surface of the pressure roller 202 is an arc-shaped concave surface. The peripheral surface of the pressure roller 202 is engraved. During the extrusion process, the cable drives the pressure roller pressed on its sheath surface to rotate. The engraving on the peripheral surface of the pressure roller is hot-pressed on the extruded sheath surface to form raised characters.

[0055] To facilitate weight control, several weight-reducing holes are provided in the pressure roller 202.

[0056] Specifically, the wheel frame 201 can be a fork-shaped arm, and the pressure roller 202 is connected between the fork-shaped arms. The pressure roller 202 is rotatably connected to the wheel frame 201 through its axle, and the wheel frame 201 is connected to the first end of the rotating member 1.

[0057] Furthermore, it also includes two adjusting bolts 203. For ease of adjustment, in this embodiment, two adjusting bolts 203 are provided, which are screwed to the far end of the fork-shaped arm of the wheel frame 201. The end of the adjusting bolt 203 is rotatably connected to the wheel axle of the pressure roller 202. Specifically, the end of the adjusting bolt 203 can be rotatably connected to the wheel axle by means of sleeve. In this embodiment, the end of the adjusting bolt 203 is provided with a positioning hole, and the end of the wheel axle is inserted into the positioning hole. The wheel axle and the adjusting bolt 203 are coaxially arranged to ensure the free rotation of the wheel axle.

[0058] When adjusting the pressure roller 202, the translational position of the pressure roller 202 is adjusted by controlling the screw-in length of the adjusting bolt 203, that is, the pressure roller 202 is adjusted to move left and right along its axis to accommodate cables of different specifications and sizes.

[0059] like Figure 2As shown, to ensure the tightness of the adjusting bolt 203 and the wheel frame 201, a fastening nut 204 for fastening the adjusting bolt 203 and the wheel frame 201 is screwed onto the adjusting bolt 203. Each adjusting bolt 203 is equipped with at least one fastening nut 204. To ensure the fastening effect, two fastening nuts 204 can be configured on the adjusting bolt 203. Two fastening nuts 204 are respectively provided on the two adjusting bolts 203 at both ends of the wheel axle. First, a fastening nut 204 is screwed onto the adjusting bolt 203, then it passes through the wheel frame 201 and then through another fastening nut 204 before being rotatably connected to the wheel axle. The two fastening nuts 204 are tightened and fixed to the adjusting bolt 203 on the wheel frame 201. After the fastening nuts 204 are tightened, they can cooperate with the adjusting bolt 203 to fix them on the wheel frame 201. When adjustment is needed, the fastening nuts 204 can be loosened.

[0060] The adjustment component 3 can be implemented using a drive device such as a cylinder or push-pull rod, to ensure that the rotating part 1 can rotate in both directions.

[0061] In this embodiment, the adjustment component 3 includes an adjustment rod 301 and a weight block 302. The weight block 302 drives the rotating component 1 to rotate, providing driving force.

[0062] The middle part of the adjusting rod 301 is connected to the second end of the rotating member 1. The connection between the middle part of the adjusting rod 301 and the second end of the rotating member 1 ensures that when the weight block 302 moves on the adjusting rod 301, it can find a point where the weight of the pressure roller assembly 2 is balanced with the weight of the two ends through the rotating member 1. The weight block 302 is slidably connected to the adjusting rod 301. The left and right movement of the weight block 302 at the balance point can drive the rotating member 1 and the pressure roller assembly 2 to rotate in both directions. Thus, the downward pressure can be adjusted by using the cooperation of the adjusting rod 301 and the weight block 302. After the weight block 302 is fixed at different positions on the adjusting rod 301, it combines with the lever formed by the rotating member 1 to drive the pressure roller assembly 2 to rotate clockwise or counterclockwise around the rotating member 1, thereby adjusting the pressure on the cable.

[0063] To ensure that the weight block 302 is fixed in position on the adjusting rod 301, a fastener 303 is screwed onto the weight block 302. The fastener 303 passes through the weight block 302 and abuts against the adjusting rod 301. The fastener 303 can be a screw or the like. After adjustment, tighten the fastener 303 to fix the position of the weight block 302 and the adjusting rod 301, and maintain this position so that the production cable can continue to complete the printing.

[0064] Since the water flow in the cooling tank is close to the printing device, in order to prevent the water flow from entering the pressure roller 202 near the pressure roller assembly 2, the cable hot pressing printing device is provided with at least one limiting seat 4. The limiting seat 4 is used to install an air pipe facing the circumference of the pressure roller 202. The limiting seat 4 can be ring-shaped, or ring-shaped with an opening to facilitate the insertion of the air pipe. Air is blown towards the circumference of the pressure roller 202 through the air pipe. The air pipe is not shown in the figure. The air pipe opening can be aligned with the circumference of the pressure roller 202 to dissipate heat from the printing roller, prevent the pressure roller from sticking to the sheath during the rolling printing process, and prevent the printing roller temperature from being too high and damaging the cable.
