Description

Technical Field

[0001] This utility model belongs to the technical field of colloid production equipment, and in particular relates to a multi-station adhesive strip production line. Background Technology

[0002] Door and window sealing strips are a type of sealing strip mainly used in architectural decorative doors and windows such as PVC, aluminum alloy, and wooden doors and windows. These sealing strips play a crucial role in waterproofing, sealing, and energy conservation in PVC, thermally broken aluminum, and wooden doors and windows. After being extruded and stretched into shape, the sealing strips can tightly fill the gaps between doors and windows, forming a good sealing effect.

[0003] Chinese Patent CN117048013B discloses a multi-head extrusion production system for door and window sealing strips. The system includes an extruder, vulcanizing equipment, and a processing tank, as well as a winding rack. A finished product wheel is detachably mounted on the winding rack, and the finished product strip rotates relative to the winding rack. The finished product strip is wound around the circumference of the finished product wheel. The winding rack also includes a drive mechanism for rotating the finished product wheel. This system creates a smooth production line for the sealing strip from production to winding.

[0004] However, the above solution still has some shortcomings. This solution uses a drive mechanism to pull the rubber strip, and its torque transmission component includes multiple torque transmission gears, making the drive mechanism structure complex. This makes it inconvenient to pull and stretch the rubber strip. Furthermore, the rubber strip's residence time in the vulcanization equipment is relatively short, which is detrimental to the vulcanization process; additionally, the efficiency of extruding the rubber strip using a single extruder is low. Utility Model Content

[0005] The purpose of this invention is to provide a multi-station adhesive strip production line to solve the problems existing in the background art.

[0006] The objective of this utility model is achieved through the following technical solution:

Detailed Implementation

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] See Figures 1-3 This utility model provides a technical solution:

[0026] like Figures 1-3 As shown, a multi-station rubber strip production line includes an extruder 1, a vulcanizing equipment 2, and a traction mechanism 3. The two sets of extruders 1 are located on both sides of the vulcanizing equipment 2, and the traction mechanism 3 is located between the two sets of extruders 1 and below the vulcanizing equipment 2. The traction mechanism 3 includes a first belt drive assembly 31 and a second belt drive assembly 32.

[0027] The rubber strips 4 extruded by the extruders 1 on both sides can be fed into the vulcanizing equipment 2 in the middle through the traction mechanism 3, so as to vulcanize the two sets of rubber strips 4 and improve the processing efficiency.

[0028] Specific examples Figure 1 and Figure 2 As shown, the traction mechanism 3 includes a first belt drive assembly 31 and a second belt drive assembly 32. The first belt drive assembly 31 includes a first driving pulley 311, a first driven pulley 312 and a first belt 313. The first driving pulley and the first driven pulley 312 are located on both sides of the vulcanizing equipment 2, and the first belt 313 passes through the vulcanizing equipment 2 and wraps around the first driving pulley 311 and the first driven pulley 312.

[0029] The second belt drive assembly 32 is located on both sides of the first belt drive assembly 31. The second belt drive assembly 32 includes a second driving pulley 321, a second driven pulley 322, a third driven pulley 323, a fourth driven pulley 324, a first guide pulley 325, a second guide pulley 326, a third guide pulley 327, a fourth guide pulley 328, and a second belt 329. The second belt 329 is located outside the first belt 313.

[0030] A first feed inlet is provided between the first driving wheel 311 and the second driving wheel 321, a first discharge outlet is provided between the first driving wheel 311 and the fourth driven wheel 324, a first discharge outlet is provided between the second driven wheel 322 and the first driven wheel 312, a second feed inlet is provided between the first driven wheel 312 and the third driven wheel 323, and a second discharge outlet is provided between the first driving wheel 311 and the fourth driven wheel 324.

[0031] The first guide wheel 325 and the fourth guide wheel 328 are located on both sides of the first belt drive assembly 31, the second guide wheel 326 and the third guide wheel 327 are located on both sides of the first belt drive assembly 31, and the second belt 329 passes sequentially around the second driving wheel 321, the second driven wheel 322, the second guide wheel 326, the third guide wheel 327, the third driven wheel 323, the fourth driven wheel 324, the fourth guide wheel 328 and the first guide wheel 325.

[0032] Through the above technical solution, since both the bottom of the first drive wheel 311 and the second drive wheel 321 are equipped with drive motors 5, the first drive wheel 311 rotates continuously, driving the first belt 313 to rotate continuously; at the same time, the second drive wheel 321 also drives the second belt 329 to rotate continuously. Since the rotation directions of the first drive wheel 311 and the second drive wheel 321 are opposite, the transmission directions of the first belt 313 and the second belt 329 are also opposite. Therefore, when the extruded rubber strip 4 enters the feed inlet, it will be pulled and driven by the first belt 313 and the second belt 329 in the same direction. The rubber strip 4 is sandwiched between the first belt 313 and the second belt 329 for transmission, and then discharged from its respective outlet. This enables multi-station operation, allowing two sets of rubber strips 4 to undergo vulcanization treatment simultaneously, thus improving processing efficiency.

[0033] like Figure 3 As shown, further, the cross-sections of the first driving wheel 311, the first driven wheel 312, the second driving wheel 321, the second driven wheel 322, the third driven wheel 323, the fourth driven wheel 324, the first guide wheel 325, the second guide wheel 326, the third guide wheel 327, and the fourth guide wheel 328 are H-shaped, and the cross-sections of the first belt 313 and the second belt 329 are I-shaped. The rubber strip 4 extruded by the extruder 1 is located in the I-shaped grooves of the first belt 313 and the second belt 329.

[0034] Through the above technical solution, the first belt 313 and the second belt 329 will not fall off from their corresponding pulleys due to the H-shaped slots, ensuring stable operation of the first belt 313 and the second belt 329. The rubber strip 4 can also maintain stable operation and will not fall off through the I-shaped slots of the first belt 313 and the second belt 329.

[0035] Furthermore, a support guide wheel 33 is provided below the first belt 313 and the second belt 329. The first belt 313 and the second belt 329 are engaged in the groove of the support guide wheel 33 to prevent the first belt 313 and the second belt 329 from collapsing in the middle when they are too long, thus ensuring that the first belt 313 and the second belt 329 run smoothly.

[0036] like Figure 2 As shown, in another embodiment, according to processing needs, one extruder 1 is shut down, and arc-shaped baffles 6 are provided at the positions of the first discharge port and the second feed port. At this time, the rubber strip 4 entering from the first feed port is blocked by the arc-shaped baffle 6 after exiting from the first discharge port via the traction mechanism 3. Then, the rubber strip 4 re-enters the second feed port along the inner wall of the arc-shaped baffle 6, and then exits from the second discharge port again via the traction mechanism 3. In this case, the rubber strip 4 undergoes vulcanization treatment twice in the vulcanization equipment 2, which can improve the vulcanization effect of the rubber strip 4.

[0037] Meanwhile, the feeding and discharging of the rubber strip 4 are located on the same side, so that the subsequent coiling and collection of the rubber strip 4 can be carried out on one side of the extruder 1, which is more convenient to operate and makes the overall production line less long, avoiding the need for personnel to go back and forth for inspection and operation.

[0038] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
