Description

Technical Field

[0001] This utility model belongs to the technical field of cord processing equipment, specifically a cord joint electric heating device. Background Technology

[0002] In the industrial production of tires, rubber products, and other products, cord is the core reinforcing skeleton material. The quality of its connection directly determines the structural strength and service life of the final product. Therefore, the cord splicing process is a key link in the production process to ensure product performance.

[0003] To achieve effective bonding of cords, the industry commonly employs a combination of heating and pressing techniques. Cord joint heating devices are widely used, their core principle being to activate the adhesive's viscosity through heating and apply pressure to achieve tight bonding between the cord layers. However, existing devices still have several areas for improvement in actual production scenarios: Regarding ease of operation, traditional devices often require manual assistance for steps such as cord positioning, alignment, and air venting in the joint area. This not only increases operational intensity but also typically relies on two or more skilled operators, placing high demands on manpower. In terms of process coordination, the heating system and pressing mechanism are not well-coordinated, resulting in uneven heat transfer and difficulty in effectively preventing air residue in the joint area during pressing. This can easily lead to defects such as bubbles and incomplete connections, affecting joint strength and stability, and even increasing the risk of cracking during subsequent use. Furthermore, the high required temperature results in significant steam consumption. Simultaneously, existing devices have limited precise temperature control, leading to occasional localized temperature anomalies or mismatches between heating and pressing rhythms, further affecting the consistency of joint quality and reducing production efficiency to some extent. Therefore, improvements are needed. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric heating device for a cord connector, comprising a base, a fixed frame fixedly connected to the top of the base, a connecting block fixedly connected to the top of the inner surface of the fixed frame, an upper mounting box fixedly connected to the bottom of the connecting block, a hydraulic cylinder fixedly connected to the top of the base, a lower mounting box fixedly connected to the top of the hydraulic cylinder, an electric heating plate fixedly installed inside both the upper and lower mounting boxes, a lower heat spreader fixedly installed on the top of the lower mounting box, an upper heat spreader fixedly connected to the bottom of the upper mounting box, temperature probes fixedly installed on the front and back of both the lower and upper mounting boxes, mounting blocks fixedly installed on the front and back of the lower heat spreader, a needle fixedly connected to the top of the mounting block, and a microcontroller and a controller fixedly installed on the front of the connecting block, respectively.

[0006] As a preferred embodiment of this utility model, side plates are fixedly installed on both the left and right sides of the front and back of the fixed frame, and a round shaft is movably sleeved between the side plates, with a round roller fixedly sleeved on the outer surface of the round shaft.

[0008] As a preferred embodiment of this utility model, an upper clamping plate is fixedly connected to the top of the vertical rod, and the outer surface of the upper clamping plate is fixedly connected to the inner surface of the fixing frame.

[0009] As a preferred embodiment of this utility model, the outer surface of the vertical rod is movably fitted with a lower clamping plate. There are two lower clamping plates, and the outer surfaces of both lower clamping plates are movably connected to the inner surface of the fixed frame. The outer end of the lower clamping plate is fixedly connected to a connecting plate, and the outer end of the connecting plate penetrates the fixed frame and extends to the outside of the fixed frame and is movably fitted with the inner wall of the fixed frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a hydraulic cylinder, an electric heating plate, a temperature probe, and a needle, allows for the heating and joining of the fabric joint. By activating the hydraulic cylinder and the electric heating plate, the lower and upper heat spreaders can be closed to heat the fabric. Simultaneously, the temperature probe can monitor the temperature of the lower and upper heat spreaders, enabling localized temperature control and preventing cracking due to abnormal temperatures. Furthermore, the upward movement of the lower heat spreader causes the needle to rise, piercing the fabric and fixing the relative position of the two rolls. It also pierces the fabric layer in the joint area, allowing air or gas to escape through tiny needle holes, preventing poor adhesion and insufficient joint strength caused by air bubbles after heating. This eliminates the extra step of manually venting air with tools, reducing operational steps and directly lowering labor intensity.

[0014] 2. This utility model, by setting up a drive motor, a rotating rod, a hinge rod, and a lower clamping plate, after the adjustment of the curtain joint area is completed, starts the drive motor, causing the rotating shaft to rotate, thereby causing the hinge rod to push the lower clamping plate to rise. This allows the lower clamping plate to cooperate with the upper clamping plate to clamp and fix the overlapping area of ​​the two curtains, thus avoiding misalignment of the curtains before joining.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides an electric heating device for a cord connector, including a base 1, a fixed frame 2 fixedly connected to the top of the base 1, a connecting block 3 fixedly connected to the top of the inner surface of the fixed frame 2, an upper mounting box 4 fixedly connected to the bottom of the connecting block 3, a hydraulic cylinder 5 fixedly connected to the top of the base 1, a lower mounting box 6 fixedly connected to the top of the hydraulic cylinder 5, an electric heating plate 7 fixedly installed inside both the upper and lower mounting boxes 4, a lower heat spreader 8 fixedly installed on the top of the lower mounting box 6, an upper heat spreader 9 fixedly connected to the bottom of the upper mounting box 4, temperature probes 10 fixedly installed on the front and back of both the lower and upper mounting boxes 6, mounting blocks 11 fixedly installed on the front and back of the lower heat spreader 8, a needle 12 fixedly connected to the top of the mounting block 11, and a microcontroller 13 and a controller 14 fixedly installed on the front of the connecting block 3 respectively.

[0023] By activating the hydraulic cylinder 5, the lower mounting box 6 and the lower heat spreader 8 are moved upward, thereby pressurizing the fabric joint between the lower heat spreader 8 and the upper heat spreader 9. When the electric heating plate 7 is activated, it heats the fabric joint between the lower heat spreader 8 and the upper heat spreader 9, thus achieving the joining of the fabric joint. Due to the design of the temperature probe 10, it can monitor the temperature of the lower heat spreader 8 and the upper heat spreader 9 and send a signal to the microcontroller 13. The microcontroller 13 then controls the local temperature of the electric heating plate 7 through the controller 14, thereby achieving local temperature regulation of the lower heat spreader 8 and the upper heat spreader 9 and preventing cracking caused by abnormal temperature.

[0024] Among them, side plates 15 are fixedly installed on the left and right sides of the front and back of the fixed frame 2, and a round shaft 16 is movably sleeved between the side plates 15. A round roller 17 is fixedly sleeved on the outer surface of the round shaft 16.

[0025] By setting the circular roller 17, the fabric can be guided and supported.

[0026] Among them, fixing blocks 18 are fixedly installed on both the left and right sides of the inner surface of the fixing frame 2, and vertical rods 19 are fixedly sleeved inside the fixing blocks 18.

[0027] By setting the fixing block 18, the vertical rod 19 can be supported and fixed.

[0028] The top of the vertical rod 19 is fixedly connected to the upper clamping plate 20, and the outer surface of the upper clamping plate 20 is fixedly connected to the inner surface of the fixed frame 2.

[0029] There are two upper clamping plates 20, and the two upper clamping plates 20 are the same size.

[0030] Among them, the outer surface of the vertical rod 19 is movably sleeved with a lower clamping plate 21. There are two lower clamping plates 21. The outer surfaces of the two lower clamping plates 21 are movably connected to the inner surface of the fixed frame 2. The outer end of the lower clamping plate 21 is fixedly connected to a connecting plate 22. The outer end of the connecting plate 22 passes through the fixed frame 2 and extends to the outside of the fixed frame 2 and is movably sleeved with the inner wall of the fixed frame 2.

[0031] When the clamping plate 21 moves upward, it will clamp and fix the curtain fabric, thereby making the curtain fabric joint more stable and avoiding misalignment of the joint.

[0032] The fixed frame 2 has mounting brackets 23 fixedly installed on both the left and right sides. The mounting brackets 23 have drive motors 24 fixedly installed inside. The other end of the output shaft of the drive motor 24 is fixedly connected to a rotating shaft 25. A rotating rod 26 is fixedly sleeved on the outer surface of the rotating shaft 25.

[0033] When the drive motor 24 starts, it will cause the rotating shaft 25 to rotate, which in turn will drive the rotating rod 26 to rotate.

[0034] The top of the rotating rod 26 is hinged to a hinge rod 27, and the top of the hinge rod 27 is hinged to the bottom of the connecting plate 22.

[0035] When the rotating rod 26 rotates, it will push the connecting plate 22 upward through the hinge rod 27, thereby causing the lower clamping plate 21 to rise under the limiting action of the vertical rod 19.

[0036] Working principle and usage process of this utility model:

[0037] When the operator joins the curtain fabric, after adjusting the curtain fabric joint area, the operator starts the drive motor 24, which causes the rotating shaft 25 to drive the rotating rod 26 to rotate. At this time, the hinge rod 27 will push the connecting plate 22 to rise, so that the lower clamping plate 21 rises under the limiting action of the vertical rod 19. This allows the lower clamping plate 21 and the upper clamping plate 20 to cooperate to clamp and fix the overlapping area of ​​the two curtain fabrics, thereby avoiding misalignment of the curtain fabrics before joining.

[0038] The operator then activates the hydraulic cylinder 5 and the electric heating plate 7. The activation of the hydraulic cylinder 5 will cause the lower mounting box 6 and the lower heat spreader 8 to move upwards, thus pressurizing the fabric joint between the lower and upper heat spreaders 8 and 9. Simultaneously, the upward movement of the lower heat spreader 8 will cause the needles 12 to rise, allowing them to pierce the fabric and fix the relative positions of the two rolls of fabric. The needles can also pierce the fabric layers in the joint area, expelling air or gas between the fabric layers through tiny needle holes. The operator can adjust the pressing pressure by controlling the hydraulic cylinder 5. When the electric heating plate 7 is activated, it will heat the fabric joint through the lower and upper heat spreaders 8 and 9, thus achieving the joining of the fabric joint. At this time, the temperature probe 10 will monitor the temperature of the lower and upper heat spreaders 8 and 9 and send a signal to the microcontroller 13. The microcontroller 13 will then control the local temperature of the electric heating plate 7 through the controller 14, thereby regulating the local temperature of the lower and upper heat spreaders 8 and 9 to prevent cracking caused by abnormal temperature.
