[0002] In the field of rubber strip manufacturing technology, after rubber is produced and molded, it needs to immediately undergo water cooling and drying processes for shaping. Existing water cooling and shaping devices for rubber strips, such as the rubber strip cooling device disclosed in utility model patent CN222858556U and the rubber strip drying device disclosed in utility model patent CN222858497U, can meet the needs to a certain extent. However, because they use the method of pulling one end of the rubber strip forward to complete the cooling and drying process, the rubber strip is inevitably kept in a taut state throughout the cooling and drying process. This results in the incompletely shaped rubber strip being under tension, which affects product quality. Therefore, it is necessary to develop a new pretreatment device to solve the above-mentioned problems existing in the current rubber strip manufacturing method. Summary of the Invention

[0016] The rubber strip vulcanization pretreatment device includes a cooling component 4, an output component 2, a drying box 1, and a draining component 3.

[0017] The drying chamber 1 includes a chamber body 13, a blower fan 17, a drying motor 14, a transmission chain 15, and a rotating rod 16 (see the instruction manual appendix). Figure 1 , 2 (and 14). The box body 13 has an overall elliptical structure. The upper end of the box body 13 has an open structure; The upper middle part of the box body 13 is equipped with a transmission chain 15 via a drying motor 14 and a transmission sprocket (see the instruction manual appendix). Figure 1 and 14 When the air-drying motor 14 is working, it can drive the transmission chain 15 to rotate.

[0018] A rotating rod 16 is mounted on the chain plate of the transmission chain 15; one end of the rotating rod 16 extends to the inside of the box body 13 and is slidably connected thereto; when the transmission chain 15 rotates, it can drive the rotating rod 16 to rotate synchronously. In this way, when the rubber strip is placed on the rotating rod 16, the rotating rod 16 can drive the rubber strip to rotate around the middle of the box body 13 on the upper surface of the box body 13.

[0019] Multiple blowers 17 are evenly distributed on the outer side of the main body 13 (see instruction manual appendix). Figure 1 , 2 (and 14). When the blower fan 17 is working, it can form an upward-flowing dry airflow inside the housing body 13; thus, as the rotating rod 16 drives the rubber strip to move, the dry airflow can dry the rubber strip.

[0020] The upper end face of the rotating rod 16 is provided with anti-slip teeth (not shown in the attached diagram of the instruction manual). The purpose of providing anti-slip teeth is to increase the coefficient of friction between the rotating rod 16 and the rubber strip during operation, so as to prevent the rubber strip from easily slipping off the rotating rod 16.

[0021] The drying chamber 1 is symmetrically equipped with an output component 2 and a draining component 3 at one end (see instruction manual). Figure 1 , 2 and 3).

[0022] Output component 2 includes a planar belt conveyor 18 and a pressure roller B19 (see attached instruction manual). Figure 8 and 9 A planar belt conveyor 18 is mounted on one end of the box body 13. The planar belt conveyor 18 is an externally purchased device; a pressure roller B19 is mounted on the planar belt conveyor 18.

[0023] Each pressure roller B19 includes a support 20, a rotating shaft 21, a swing arm 22, and a rotating pressure roller 23; two sets of swing arms 22 are symmetrically mounted on the support 20 via the rotating shaft 21; the rotating pressure roller 23 is installed between the swing arms 22 (see the appendix of the instruction manual). Figure 8 and 9 ).

[0024] A clamping device 24 is installed between the swing arm 22 of the pressure roller B19 and the flat belt conveyor 18. The clamping device 24 includes a lug 25, a clamping spring 27, and a guide pin 42; the lug 25 is fixedly mounted on the outer side of the swing arm 22; the lug 25 is provided with an elongated sliding hole 26; the guide pin 42 passes through the elongated sliding hole 26 and is fixedly connected to the corresponding flat belt conveyor 18 or the recovery box 5; the clamping spring 27 is fitted on the guide pin above the lug 25; the clamping spring 27 abuts against the top cap of the guide pin 42.

[0025] The purpose of arranging the pressure roller B19 and the clamping device 24 in this way is to ensure that the swing arm 22 always has a downward rotation tendency under the action of the clamping spring 27; thus, it can be ensured that the rotating pressure roller 23 always has a downward tendency to approach the flat belt conveyor 18. When the dried rubber strip is placed on the surface of the flat belt conveyor 18, as the flat belt conveyor 18 moves the rubber strip forward, the rotating pressure roller 23 can rotate synchronously under the drive of the flat belt conveyor 18; thus, the rubber strip will always be in contact with the flat belt conveyor 18 under the pressure of the rotating pressure roller 23, thereby ensuring the smooth output of the rubber strip and avoiding the problem of the rubber strip deviating from the running trajectory.

[0026] The drain assembly 3 includes a recovery tank 5, a pressure roller A9, a draining motor 6, a drain conveyor belt 8, a passive pressure belt A12, and a tensioner A11 (see the instruction manual appendix). Figure 10 , 11 and 12).

[0027] A recycling box 5 is installed at one bottom of the drying box 1; one end of the recycling box 5 extends into the interior of the drying box 1. A drain conveyor belt 8, which is a mesh conveyor belt, is mounted above the recycling box 5 and one end of the drying box 1 via a drain motor 6 and multiple drive shafts 7. There is a certain gap between the drain conveyor belt 8 and the bottom of the recycling box 5; during operation, it is necessary to ensure that the liquid level in the recycling box 5 is always below the drain conveyor belt 8; thus, when the drain conveyor belt 8 moves the rubber strip cooled by the coolant, the coolant adhering to the rubber strip will pass through the drain conveyor belt 8 under the action of gravity and fall into the recycling box 5 to complete the recycling.

[0028] The portion of the drain conveyor belt 8 located above the drying box 1 is horizontal, while the portion inside the recycling box 5 is V-shaped (see instruction manual appendix). Figure 10 and 11 The purpose of setting up the drain conveyor belt 8 in this way is to increase the overall surface length of the drain conveyor belt 8 by utilizing the V-shaped structure, so that the rubber strip stays on the recovery box 5 for a longer time during operation, thereby enhancing the coolant recovery effect.

[0029] The inside of the recycling box 5 above the leaching conveyor belt 8 is equipped with a pressure roller A9 (see the instruction manual appendix). Figure 10 and 11 ).

[0030] The pressure roller A9 includes a support 20, a rotating shaft 21, a swing arm 22, and a rotating pressure roller 23; two sets of swing arms 22 are symmetrically mounted on the support 20 via the rotating shaft 21; and the rotating pressure roller 23 is installed between the swing arms 22.

[0031] A clamping device 24 is installed between the swing arm 22 of the pressure roller A9 and the recycling box 5. The clamping device 24 includes a support lug 25, a clamping spring 27, and a guide pin 42; the support lug 25 is fixedly installed on the outer side of the swing arm 22; the support lug 25 is provided with an elongated sliding hole 26; the guide pin 42 passes through the elongated sliding hole 26 and is fixedly connected to the corresponding planar belt conveyor 18 or recycling box 5; the clamping spring 27 is fitted on the guide pin above the support lug 25; the clamping spring 27 abuts against the top cap of the guide pin 42.

[0032] The purpose of this arrangement of the pressure roller A9 is to ensure that the rotating pressure roller 23, in conjunction with the clamping device 24, consistently presses the drain conveyor belt 8 (see the instruction manual appendix). Figure 11 and 12 ).

[0033] When working in this way, the passively rotating pressure roller 23 can squeeze the rubber strip, which can make the rubber strip move together with the drain conveyor belt 8; and can make the rotating pressure roller 23 drive some of the coolant on the surface of the drain conveyor belt 8 to separate from the drain conveyor belt 8, thereby achieving a better draining effect.

[0034] A passive pressure belt A12 is mounted on the drying box 1 above the drain conveyor belt 8 via multiple positioning belt shafts 10 and tensioners A11; the lower surface of the passive pressure belt A12 is in contact with the upper surface of the drain conveyor belt 8.

[0035] Positioning belt shafts 10 are installed on the drying box 1 at one end of the horizontal section of the drain conveyor belt 8 and on the drying box 1 above it, respectively; a tensioner A11 is installed on the recycling box 5 at the other end of the horizontal section of the drain conveyor belt 8; a passive pressure belt A12 is installed between the positioning belt shaft 10 and the tensioner A11.

[0036] The tensioner A11 includes a movable belt shaft 36, two sets of assembly frames 34, sliding bearing seats 35, adjusting screws 38, pressing sliding plates 37, and compression springs 41. The two sets of assembly frames 34 are symmetrically arranged. Sliding bearing seats 35 are slidably mounted in the assembly frames 34 via guide rails. The movable belt shaft 36 is installed between the sliding bearing seats 35. A pressing sliding plate 37 is slidably mounted in the assembly frame 34 on one side of the sliding bearing seats 35. An adjusting screw 38 is connected to the assembly frame 34 on the side of the pressing sliding plate 37. The lower end of the adjusting screw 38 is movably connected to the pressing sliding plate 37. Guide pins 39 are symmetrically mounted on the sliding bearing seats 35. After passing through the pressing sliding plate 37, the guide pins 39 are fitted with limit caps 40. A compression spring 41 is fitted on the guide pins 39.

[0037] The purpose of this tensioner A11 configuration is to allow the adjusting screw 38 to move the pressure sliding plate 37 along the assembly frame 34 during operation. As the pressure sliding plate 37 moves, the guide pin 39 drives the sliding bearing seat 35 to move synchronously, thus adjusting the position of the rotating pressure roller 23. During operation, the adjusting screw 38 can be used to adjust the rotating pressure roller 23 to tighten the passively pressing belt A12. In this process, after the passively pressing belt A12 is compressed, the movable belt shaft 36 can drive the sliding bearing seat 35 to compress the compression spring 41 a certain distance, providing a buffer space for the passively pressing belt A12 and ensuring that the passively pressing belt A12 always has a tendency to press the drain conveyor belt 8. Thus, when the drain conveyor belt 8 rotates, it drives the passively pressing belt A12 to rotate synchronously.

[0038] When the rubber strip moves between the drain conveyor belt 8 and the passive pressing belt A12, the drain conveyor belt 8 and the passive pressing belt A12 can drive the rubber strip forward by extrusion conveying. In this process, since the drain conveyor belt 8 and the passive pressing belt A12 are in full contact with the surface of the rubber strip before driving it forward, it can solve the problem of the existing rubber strip being tightened by applying force to one end when it cools, which affects the product quality, by uniformly applying force.

[0039] A cooling component 4 is provided at one end of the drainage component 3 (see instruction manual). Figure 3 and 4 The cooling assembly 4 includes a cooling water tank 43, a tensioner B32, a passive pressure belt B33, a cooling conveyor belt 31, a cooling motor 29, and a feeding belt conveyor 28 (see the instruction manual appendix). Figure 5 , 6 and 7).

[0040] A feeding belt conveyor 28 is installed at an angle at one end of the cooling water tank 43 (see instruction manual appendix). Figure 5 and 6 The feeding belt conveyor 28 is an externally purchased device. When the rubber strip is placed on the feeding belt conveyor 28 during operation, the rotating feeding belt conveyor 28 can drive the rubber strip to move towards the cooling water tank 43.

[0041] Two sets of guide rollers 44 are symmetrically arranged at the inlet end of the feeding belt conveyor 28. The purpose of setting the guide rollers 44 is to allow the rubber strip to be placed on the feeding belt conveyor 28 through the position between the two sets of guide rollers 44 during operation. This ensures that the rubber strip can enter the feeding belt conveyor 28 from the middle.

[0042] The interior of the cooling water tank 43 is equipped with a cooling conveyor belt 31 with a mesh conveyor belt via a cooling motor 29 and a conveyor belt shaft 30 (see the instruction manual appendix). Figure 5 and 6 The cooling conveyor belt 31 has an overall trumpet-shaped structure.

[0043] The cooling water tank 43 is connected to an external coolant control device through a pipe; during operation, the external coolant control device can control the coolant level in the cooling water tank 43 to a suitable position; at this time, the bottom of the cooling conveyor belt 31 is immersed in the coolant.

[0044] The cooling water tank 43 and the recovery tank 5 are connected by a heat exchanger and a transfer pump (not shown in the attached diagram of the instruction manual). During operation, the coolant recovered in the recovery tank 5 is cooled by the heat exchanger and then pumped back into the cooling water tank 43 to participate in the circulation process.

[0045] Inside the cooling water tank 43 above the cooling conveyor belt 31, a passive pressure belt B33 is installed via a positioning belt shaft 10 and a tensioner B32; the passive pressure belt B33 is in close contact with the cooling conveyor belt 31 (see the instruction manual appendix). Figure 5 and 6 ).

[0046] Each tensioner B32 includes a movable belt shaft 36, two sets of assembly frames 34, sliding bearing seats 35, adjusting screws 38, pressing slide plates 37, and compression springs 41. The two sets of assembly frames 34 are symmetrically arranged. Sliding bearing seats 35 are slidably mounted in the assembly frames 34 via guide rails. The movable belt shaft 36 is installed between the sliding bearing seats 35. A pressing slide plate 37 is slidably mounted in the assembly frame 34 on one side of the sliding bearing seat 35. An adjusting screw 38 is connected to the assembly frame 34 on one side of the pressing slide plate 37. The lower end of the adjusting screw 38 is movably connected to the pressing slide plate 37. Guide pins 39 are symmetrically mounted on the sliding bearing seats 35. After passing through the pressing slide plate 37, the guide pins 39 are fitted with limit caps 40. A compression spring 41 is fitted on the guide pin 39 (see the attached instruction manual). Figure 5 and 7 ).

[0047] The purpose of this tensioner B32 configuration is to ensure that the passive pressure belt B33 maintains an elastic fit with the cooling conveyor belt 31 under the action of the tensioner B32. Thus, when the rubber strip enters between the passive pressure belt B33 and the cooling conveyor belt 31, the passive pressure belt B33 and the cooling conveyor belt 31 can drive the rubber strip forward in the coolant through compression, thereby completing the cooling process. During this process, because the rubber strip moves forward under the overall compression of the passive pressure belt B33 and the cooling conveyor belt 31, its overall force is uniform. This solves the problem of existing rubber strip cooling methods where tension is applied to one end, affecting product quality.

[0048] When the rubber strip vulcanization pretreatment device is working, one end of the continuous rubber strip to be cooled is first placed on the feeding belt 28; when the feeding belt 28 is working, it can transport the rubber strip between the passive pressing belt B33 and the cooling conveyor belt 31 of the cooling water tank 43 of the cooling component 4.

[0049] In the cooling assembly 4, the rotating cooling conveyor belt 31 drives the passive pressure belt B33 to rotate. At the same time, the passive pressure belt B33 and the cooling conveyor belt 31 can drive the rubber strip forward in the coolant by squeezing and conveying, thus completing the cooling work.

[0050] After the passive pressing belt B33 and cooling conveyor belt 31 of the cooling component 4 drive the cooled rubber strip out of the cooling water tank 43, one end of the rubber strip passes between the drain conveyor belt 8 and the rotating pressure roller 23 of the drain component 3, and finally enters between the drain conveyor belt 8 and the passive pressing belt A12. At this time, the rubber strip is driven forward by the squeezing conveyor belt A12 as the drain conveyor belt 8 drives the passive pressing belt A12 to rotate. During this process, the coolant attached to the surface of the rubber strip will fall into the inside of the recycling box 5 under the action of gravity to complete the recycling.

[0051] Thus, the draining assembly 3 completes the draining process. After the drained rubber strip enters the upper part of the drying chamber 1 and rests on the rotating rod 16, the rotating rod 16 will drive the rubber strip to move towards the output assembly 2 from the upper part of the chamber body 13. During this process, the drying airflow generated by the blower fan 17 dries the rubber strip.

[0052] When the rubber strip moves close to the output component 2, one end of it is placed between the rotating pressure roller 23 of the flat belt conveyor 18 and the pressure roller B19; then, as the flat belt conveyor 18 drives the rotating pressure roller 23 to rotate, the flat belt conveyor 18 can output the rubber strip by extrusion conveying with the cooperation of the rotating pressure roller 23.

[0053] At this point, the rubber strip vulcanization pretreatment device has completed the cooling, draining, and drying of the rubber strip, and can then continuously complete the above-mentioned work for subsequent rubber strips.

[0054] This rubber strip vulcanization pretreatment device has a compact structure and ingenious design, which enables the rubber strip to complete the water cooling, draining and air drying processes without always keeping it taut. It solves the problem of poor production quality in existing rubber strip production methods and is particularly suitable for the cooling needs of rubber strips.
