Description

Technical Field

[0001] This utility model belongs to the technical field of hot melt butt welding machines, and specifically relates to a hot melt butt welding machine equipped with a positioning structure. Background Technology

[0002] A hot-melt butt welding machine is a device used for joining plastic parts or pipes. Its working principle is based on hot-melt technology. The surface of the plastic to be welded is melted by heating. After the material reaches a suitable temperature, the two hot-melted end faces are joined together, and after cooling, a strong connection is formed. However, hot-melt butt welding machines without a positioning mechanism have significant drawbacks. Due to the lack of a positioning structure, the welded parts may shift during heating and fusion. This displacement may lead to poor contact of the high-temperature molten material, further resulting in uneven welds, weak material bonding, and ultimately insufficient strength and poor durability of the welded joint. Therefore, we aim to design a hot-melt butt welding machine equipped with a positioning structure to solve this problem. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hot melt butt welding machine equipped with a positioning structure to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a hot melt butt welding machine with a positioning structure, comprising: a base plate and a positioning mechanism, wherein a support frame is fixedly connected to the upper surface of the base plate, a positioning mechanism is provided on the inner side of the support frame, two sets of fixing mechanisms are provided on the positioning mechanism, and a hot melt plate is provided on the positioning mechanism;

[0005] The positioning mechanism includes a sliding component, which is disposed inside the support frame. A transmission component is disposed on the sliding component. By setting the positioning mechanism, the welded parts are positioned to ensure the stability and accuracy of the welded parts during the welding process, thereby reducing welding deviation.

[0006] In a preferred embodiment, the sliding assembly includes a slide rod, the two ends of which are fixedly connected to the inner side of the support frame, and a sliding sleeve is slidably sleeved on the outer side of the slide rod. By setting the sliding assembly, the position of the welded part is slidably positioned.

[0007] In a preferred embodiment, the transmission assembly includes a connecting rod, which is fixedly connected to the outside of the sliding sleeve. The lower end of the connecting rod has a threaded hole, and a threaded rod is screwed into the threaded hole. A drive motor for driving the threaded rod to rotate is provided at the left end of the threaded rod. By setting the transmission assembly, the sliding sleeve drives the fixing mechanism and the welded parts to generate displacement.

[0008] In a preferred embodiment, the fixing mechanism includes a support rod, which is fixedly connected to the outside of the sliding sleeve. A connecting plate is fixedly connected to the support rod, and a clamping assembly is provided on the inner side of the connecting plate. By setting the fixing mechanism, displacement of the welded parts during the welding process is prevented, which could lead to welding deviation.

[0009] In a preferred embodiment, the clamping assembly includes a bidirectional threaded rod that passes through the interior of the connecting plate via a bearing, and a clamping plate is threaded onto the outer side of the bidirectional threaded rod.

[0010] A reducer for driving the bidirectional threaded rod to rotate is fixedly installed on the outer side of the connecting plate. A limit component is provided on the connecting plate, and a support component is provided on the upper surface of the base plate. By setting a clamping component, welded parts of different sizes can be clamped.

[0011] In a preferred embodiment, the inner side of the clamp is provided with a rubber pad to improve its surface friction.

[0012] In a preferred embodiment, the limiting component includes a mounting plate, which is fixedly connected to the lower side of the sliding sleeve. One end of a telescopic rod is fixedly connected to the inner side of the mounting plate, and the other end of the telescopic rod is fixedly connected to the clamping plate. By setting the limiting component, the clamping plate is prevented from rotating along with the bidirectional threaded rod.

[0013] In a preferred embodiment, the support assembly includes a cylinder, which is fixedly installed on the upper surface of the base plate. The telescopic end of the cylinder is fixedly connected to a support plate for supporting the welded part. By setting up the support assembly, the phenomenon of the right side of the welded part tilting up, which would lead to inaccurate welding, is avoided.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: by setting a fixing mechanism, the welding parts are prevented from shifting during the welding process, which would ultimately lead to welding deviation and weak material bonding. Furthermore, by setting a positioning mechanism, the sliding sleeve and fixing mechanism are moved by the threaded rod to slide and position the welding part left and right, thus avoiding displacement of the fixing mechanism during the welding process, which would lead to poor contact, uneven weld, and ultimately insufficient strength and poor durability of the welded joint.

Two sets of fixing mechanisms 4 are provided on the positioning mechanism 3. A hot melt plate 5 is provided on the positioning mechanism 3.

[0025] The positioning mechanism 3 includes a sliding component 31, which is located inside the support frame 2. A transmission component 32 is provided on the sliding component 31. By setting the positioning mechanism 3, the welded parts are positioned to ensure the stability and accuracy of the welded parts during the welding process, thereby reducing welding deviation.

[0026] The sliding assembly 31 includes a slide rod 311, the two ends of which are fixedly connected to the inner side of the support frame 2. A slide sleeve 312 is slidably sleeved on the outer side of the slide rod 311. By setting the sliding assembly 31, the position of the welded part is slidably positioned.

[0027] The transmission assembly 32 includes a connecting rod 321, which is fixedly connected to the outside of the sliding sleeve 312. The lower end of the connecting rod 321 has a threaded hole, and a threaded rod 322 is screwed into the threaded hole. A drive motor for driving the threaded rod 322 to rotate is provided at the left end of the threaded rod 322. By setting the transmission assembly 32, the sliding sleeve 312 drives the fixing mechanism 4 and the welded parts to generate displacement.

[0028] The fixing mechanism 4 includes a support rod 41, which is fixedly connected to the outside of the sliding sleeve 312. A connecting plate 42 is fixedly connected to the support rod 41, and a clamping assembly 43 is provided on the inner side of the connecting plate 42. By setting the fixing mechanism 4, displacement of the welded parts during the welding process is prevented, which would lead to welding deviation.

[0029] The clamping assembly 43 includes a bidirectional threaded rod 431, which passes through the interior of the connecting plate 42 via a bearing, and a clamping plate 432 is screwed onto the outside of the bidirectional threaded rod 431 via a thread.

[0030] A reducer for driving the bidirectional threaded rod 431 to rotate is fixedly installed on the outer side of the connecting plate 42. A limit assembly 44 is provided on the connecting plate 42, and a support assembly 45 is provided on the upper surface of the base plate 1. By setting the clamping assembly 43, welding parts of different sizes can be clamped.

[0031] The inner side of the clamp 432 is provided with a rubber pad to improve its surface friction.

[0032] The limiting component 44 includes a mounting plate 441, which is fixedly connected to the lower side of the sliding sleeve 312. One end of the telescopic rod 442 is fixedly connected to the inner side of the mounting plate 441, and the other end of the telescopic rod 442 is fixedly connected to the clamping plate 432.

[0033] The support assembly 45 includes a cylinder 451, which is fixedly installed on the upper surface of the base plate 1. The telescopic end of the cylinder 451 is fixedly connected to a support plate 452 for supporting the welded parts.

Then start the drive motor. The output shaft of the drive motor drives the threaded rod 322 to rotate. During the rotation, the threaded rod 322 and the connecting rod 321 undergo threaded movement, which causes the connecting rod 321 to drive the sliding sleeve 312 to move. While the sliding sleeve 312 is moving, it drives the fixing mechanism 4 to move to adjust the left and right position of the welded part until it is stably connected with the right welded part. Then the drive motor can be turned off to complete the positioning of the welded parts.

[0035] Please see Figure 2 , Figure 4 As a second embodiment of this utility model: Based on the description in the above embodiments, further, when fixing the welded parts, the welded parts are first placed between the clamping plates 432, and then the reducer is started. The output shaft of the reducer drives the bidirectional threaded rod 431 to rotate. While rotating, the bidirectional threaded rod 431 undergoes threaded movement with the clamping plate 432, causing the clamping plate 432 to move and clamp and fix the welded parts. Then the cylinder 451 is started. The telescopic end of the cylinder 451 drives the support plate 452 to move upward to support the welded parts and prevent the right side of the welded parts from tilting up, which would cause welding deviation.
