Description

Technical Field

[0002] Vulcanized rubber refers to vulcanized rubber, which has the characteristics of not becoming sticky and not easy to break. Most rubber products are made of this rubber, also called cooked rubber, commonly known as rubber or rubber. When vulcanizing rubber, the rubber needs to be placed in a vulcanization mold and vulcanized through a rubber vulcanizer. The shape of the finished rubber product depends on the mold.

[0003] In order to meet the requirements of vulcanization of longer rubber compounds, the existing molds used in vulcanizers need to heat and vulcanize several rubber compounds continuously into an integrated mechanism when in use; however, the two ends of the rubber compound will be vulcanized twice in the mold of the vulcanizer, resulting in excessive vulcanization of the two ends of the rubber compound. The hardness of the vulcanized rubber compound increases, while its elasticity decreases, making it more fragile and brittle, etc., resulting in a low yield rate of the finished rubber compound.

The heating device 15 in this embodiment is explained as follows:

[0084] The heating device 15 in this embodiment includes a first heating component 151, a left heating component 152, and a right heating component 153.

The adjustment device 16 in this embodiment is used to adjust the position of the left heating component 152 and the right heating component 153 relative to the mold shell 14.

[0085] The heating device 15 is respectively provided with a first heating component 151, a left heating component 152 and a right heating component 153 to heat the rubber material in sections, and the structure is highly practical. The equipment is further provided with an adjusting device 16, which adjusts the position of the right heating component 152, thereby adjusting the temperature of the rubber material vulcanization in the right vulcanization area, so that the rubber material can be semi-vulcanized in the right vulcanization area. The adjusting device 16 adjusts the position of the left heating component 152, thereby adjusting the temperature of the rubber material vulcanization in the left vulcanization area, so that the rubber material can be semi-vulcanized in the left vulcanization area. The equipment performs liquid cooling on both ends of the rubber material, so that two half-temperature vulcanization operations are performed on both ends of the rubber material, thereby avoiding excessive vulcanization of both ends of the rubber material, improving the practicality of the temperature-adjustable rubber strip vulcanization equipment structure, and improving the yield rate of rubber material vulcanization, and the structure is highly practical.

[0086] Combine Figure 3 、 Figure 4 and Figure 5 , the structure of the regulating device 16 in this embodiment is described:

[0087] The adjusting device 16 includes a support base 161, a first rotating base 162, a second rotating base 163, a first driving assembly 164 and a second driving assembly 165; the support base 161 is located below the forming shell 14, and the support base 161 is connected to the first heating assembly 151; the first rotating base 162 is rotatably connected to one side of the support base 161, and the top of the first rotating base 162 is connected to the left heating assembly 152; the second rotating base 163 is rotatably connected to the other side of the support base 161, and the top of the second rotating base 163 is connected to the right heating assembly 153; the first driving assembly 164 is connected to the first rotating base 162, and the first driving assembly 164 drives the first rotating base 162 to rotate relative to the support base 161; the second driving assembly 165 is connected to the second rotating base 163, and the second driving assembly 165 drives the second rotating base 163 to rotate relative to the support base 161.

[0088] In this embodiment, the adjustment device 16 drives the first rotating seat 162 via the first drive assembly 164, causing the left heating assembly 152 to rotate relative to the support seat 161, thereby adjusting the curing temperature of the rubber material in the left curing zone by the left heating assembly 152, thereby facilitating heating of the rubber material in the left curing zone. The second drive assembly 165 drives the second rotating seat 163 to rotate the right heating assembly 153 relative to the support seat 161, thereby adjusting the curing temperature of the rubber material in the right curing zone by the right heating assembly 153, thereby facilitating heating of the rubber material in the right curing zone. In this embodiment, the adjustment device 16 is rotatably connected to the first rotating seat 162 and the second rotating seat 163 via the support seat 161, respectively. This improves the stability of the connection between the adjustment device 16 and the three heating assemblies. The two rotating seats are rotatably connected to the support seat 161, thereby facilitating the temperature of the rubber material in the right curing zone to decrease from left to right. Furthermore, the temperature of the rubber material in the left curing zone after splicing increases from left to right, thereby improving the stability of the spliced curing of the two sections of rubber material, and the structure is highly practical.

[0089] The structure of the first driving assembly 164 in this embodiment is described in detail as follows:

[0090] The first driving assembly 164 in this embodiment includes a first guide rail 1641, a first slider 1642, a first rotating rod 1643 and a first driving member 1644; wherein the first guide rail 1641 is connected to the support seat 161, and the first guide rail 1641 is vertically arranged; the first slider 1642 is slidingly arranged with the first guide rail 1641; one end of the first rotating rod 1643 is rotatably connected to the first rotating seat 162, and the other end of the first rotating rod 1643 is rotatably connected to the first slider 1642; the first driving member 1644 is connected to the first slider 1642, and the first driving member 1644 drives the first slider 1642 to slide along the first guide rail 1641.

[0091] The first driving member 1644 drives the first slider 1642 to slide upward along the first guide rail 1641, and the first slider 1642 drives the first rotating rod 1643 to rotate the first rotating seat 162 upward around one side of the support seat 161, so that the angle between the plane where the first rotating seat 162 is located and the plane where the support seat 161 is located can be adjusted, and the maximum angle is such that the plane where the first rotating seat 162 is located is roughly flush with the plane where the support seat 161 is located. This structure can adjust the heating temperature of the rubber material in the left vulcanization area by the left heating component 152, and the structure is highly practical.

[0092] The first driving assembly 164 drives the first slider 1642 to move downward along the first guide rail 1641. The first slider 1642 drives the first rotating rod 1643 to rotate the first rotating seat 162 downward around one side of the support seat 161. The first rotating seat 162 drives the left heating assembly 152 away from the molding shell 14, so that the left heating assembly 152 can reduce the heating temperature of the rubber material in the left vulcanization area, and cool the rubber material in the left vulcanization area in advance. The structure is highly practical.

[0093] The second driving assembly 165 in this embodiment is described in detail as follows:

[0094] The second driving assembly 165 in this embodiment includes a second guide rail, a second slider, a second rotating rod 1651 and a second driving member; wherein the second guide rail is connected to the support seat 161, and the second guide rail is vertically arranged; the second slider is slidingly arranged with the second guide rail; one end of the second rotating rod 1651 is rotatably connected to the second rotating seat 163, and the other end of the second rotating rod 1651 is rotatably connected to the second slider; the second driving member is connected to the second slider, and the second driving member drives the second slider to slide along the second guide rail.

[0095] The second driving member drives the second slider to slide upward along the second guide rail, and the second slider drives the second rotating rod 1651 to rotate the second rotating seat 163 upward around the other side of the support seat 161, so that the angle between the plane where the second rotating seat 163 is located and the plane where the support seat 161 is located can be adjusted, and the maximum angle is to make the plane where the second rotating seat 163 is located roughly flush with the plane where the support seat 161 is located. This structure can adjust the heating temperature of the rubber material in the right vulcanization area by the right heating component 153, and the structure is highly practical.

[0096] The second driving assembly 165 drives the second slider to move downward along the second guide rail, and the second slider drives the second rotating rod 1651 to rotate the second rotating seat 163 downward around the other side of the support seat 161. The second rotating seat 163 drives the right heating assembly 153 away from the molding shell 14, so that the right heating assembly 153 can reduce the heating temperature of the rubber material in the right vulcanization area, and cool the rubber material in the right vulcanization area in advance. The structure is highly practical.

[0097] Furthermore, in this embodiment, the second guide rail is first guide rail 1641, the second slider is first slider 1642, and the second driving member is first driving member 1644. That is, in this embodiment, one end of second rotating rod 1651 is rotatably connected to second rotating base 163, and the other end of second rotating rod 1651 is slidably connected to first slider 1642.

[0098] The other structures of the regulating device 16 in this embodiment are described in detail as follows:

[0099] Combine Figure 4 and Figure 5 In this embodiment, the adjustment device 16 further includes a shock-absorbing spring 1672, which connects the bottom surface of the support base 161 to the first slider 1642. When the adjustment device 16 is in motion, the connection between the support base 161 and the first slider 1642, via the shock-absorbing spring 1672, prevents the impact and vibration generated by the movement from being directly transmitted to other parts. The shock-absorbing spring 1672 absorbs and disperses this energy, reducing vibration and noise, and improving the stability and reliability of the device.

[0100] A positioning ring 1611 is provided at the bottom of the support seat 161, and a positioning groove is provided at the top of the first slider 1642. One end of the shock-absorbing spring 1672 is accommodated in the positioning ring 1611, and the bottom end of the shock-absorbing spring 1672 is accommodated in the positioning groove, thereby improving the structural stability of the shock-absorbing spring 1672 during use.

[0101] Combine Figure 6 and Figure 7 In this embodiment, the first slider 1642 is provided with a first connecting portion 16421 and a second connecting portion 16422, with a rotating shaft 1671 connected therebetween. The adjustment device 16 further includes a first bearing 1673, a second bearing 1674, a third bearing 1675, a fourth bearing 1676, and a fixing spring 1677. The first bearing 1673 is sleeved on the rotating shaft 1671 and is located between the first connecting portion 16421 and the first rotating rod 1643. The first bearing 1673 reduces friction between the first rotating rod 1643 and the first connecting portion 16421, thereby allowing the first rotating rod 1643 to rotate more smoothly about the rotating shaft 1671.

[0102] The third bearing 1675 is sleeved on the rotating shaft 1671 and is located between the second rotating rod 1651 and the second connecting portion 16422 . The first right-left bearing reduces the friction between the second rotating rod 1651 and the second connecting portion 16422 to facilitate the rotation of the second rotating rod 1651 .

[0103] The second bearing 1674 is sleeved on the rotating shaft 1671, and the second bearing 1674 is located on the side of the first rotating rod 1643 close to the second rotating rod 1651; the fourth bearing 1676 is sleeved on the rotating shaft 1671, and the fourth bearing 1676 is located on the side of the second rotating rod 1651 close to the first rotating rod 1643; the fixed spring 1677 is sleeved on the outside of the rotating shaft 1671, and the fixed spring 1677 connects the second bearing 1674 and the fourth bearing 1676; the fixed spring 1677 drives the second bearing 1674 and the fourth bearing 1676 to move relatively apart, has good shock absorption and positioning effects, and improves the stability of the adjustment device 16 structure during use.

[0104] Combine Figure 3 and Figure 4 In this embodiment, the lower mold mechanism 1b further includes a lifting device 166 connected to the bottom mold 13, which is in turn connected to the support base 161. The lifting device 166 drives the support base 161 to move relative to the mold shell 14, thereby reducing the cooling time of the finished rubber product. When cooling the mold shell 14, the lifting device 166 and the support base 161 are able to move away from the mold shell 14, thereby accelerating the cooling efficiency of the mold shell 14 and reducing the cooling time of the mold shell 14.

[0105] Combine Figure 2 、 Figure 8 and Figure 9 , other structures of the lower mold mechanism 1b are described:

[0106] The midsole mold 13 of the present invention is provided with ventilation holes on both sides of the hollow cavity, and a blowing mechanism 5 is provided on both sides of the hollow cavity, located at the ventilation holes. The ventilation holes cooperate with the blowing mechanism 5 to achieve rapid cooling of the molded shell 14. The blowing mechanism 5 allows external air to flow into and out of the hollow cavity through the two ventilation holes, thereby cooling the exposed molded shell 14. Since the heat source is separated from the molded shell 14, only the molded shell 14 needs to be cooled, which accelerates the cooling efficiency of the molded shell 14 and saves the cooling time of the molded shell 14.

[0107] The blowing mechanism 5 includes a positioning frame 51, a baffle 52, a connecting rod 53, an electric telescopic rod 54, a bracket 55 and a fan 56; a baffle 52 is provided on one side wall surface of the positioning frame 51, and both sides of the baffle 52 are connected to both sides of the surface of the positioning frame 51 through a driving component, and the driving component includes an electric telescopic rod 54 provided on one side of the outer wall of the positioning frame 51, the electric telescopic rod 54 is connected to the outer wall surface of the positioning frame 51 through a bracket 55, and the output end of the electric telescopic rod 54 is connected to one end of the baffle 52 through a connecting rod 53, and a fan 56 is provided in the inner cavity of the positioning frame 51. Through the positioning frame 51 in the blowing mechanism 5, both The baffle plate 52 is fixed at the ventilation hole on the hollow cavity and can be installed through the driving assembly. When the molded shell 14 needs to be cooled, the electric telescopic rod 54 in the driving assembly is extended, so that the baffle plate 52 can be driven to move downward through the connecting rod 53, so that the baffle plate 52 can be moved away from the positioning frame 51, and then the air flow can be accelerated by the fan 56, so that the cooling of the molded shell 14 can be accelerated. When the molded shell 14 needs to be heated, the electric telescopic rod 54 is contracted, and then the baffle plate 52 is driven to block the positioning frame 51, so that the hollow cavity can be made into a closed chamber to prevent heat loss.

[0108] The inner cavities of the two ventilation holes are both provided with dustproof screens 57, through which the wind passing through can be filtered, thereby preventing foreign matter from entering the hollow cavity.

[0109] The main view of the shielding plate 52 is larger than the main view of the inner cavity of the positioning frame 51, which facilitates the shielding plate 52 to shield the positioning frame 51. Two fans 56 are provided, and the two fans 56 are connected to the inner wall of the positioning frame 51 by fixing rods, which can accelerate air flow. At the same time, the fixing rods can improve the stability of the fans 56 when used in the positioning frame 51.

[0113] The temperature-adjustable rubber strip vulcanizing apparatus further includes a liquid cooling mechanism 4 connected to the left and right liquid cooling channels. The liquid cooling mechanism 4 is configured to provide condensate to the left and right liquid cooling channels, thereby cooling the rubber material in the right and left liquid cooling sections 112 and 113.

[0114] The temperature-adjustable rubber strip vulcanization equipment heats the rubber material through the lower mold mechanism, and the upper mold mechanism presses the rubber material downward. The upper mold mechanism 1a and the lower mold mechanism 1b move relative to each other to form a vulcanization molding space for accommodating the rubber material, so that the rubber material is molded; wherein, the fixed part 111 of the pressing mold 11 in the upper mold mechanism presses down the rubber material in the middle vulcanization area; the right liquid cooling part 112 is located in the right vulcanization area, and the right liquid cooling part 112 presses down the rubber material in the right vulcanization area, and the right liquid cooling part 112 includes a right liquid cooling channel; the left liquid cooling part 113 at the other end of the pressing mold 11 is located in the left vulcanization area, and the left liquid cooling part 113 presses down the rubber material in the left vulcanization area, and the left liquid cooling part 113 includes a left liquid cooling channel. Liquid cooling channels are provided at both ends of the corresponding rubber material of the pressing mold to connect to the liquid cooling mechanism 4, so as to perform liquid cooling on both ends of the rubber material, so that two half-temperature vulcanization operations are performed on both ends of the rubber material respectively, thereby avoiding excessive vulcanization of both ends of the rubber material, improving the practicality of the temperature-adjustable rubber strip vulcanization equipment structure, improving the yield rate of rubber material vulcanization, and having strong structural practicality.

[0115] The liquid cooling mechanism 4 in this embodiment is described in detail:

[0116] The liquid cooling mechanism 4 includes a left liquid cooling device and a right liquid cooling device. The left liquid cooling device includes a first left liquid cooling tank 41 and a second left liquid cooling tank 42. Two groups of left liquid cooling channels are provided: a first left liquid cooling channel 1131 and a second left liquid cooling channel 1132. The first left liquid cooling channel 1131 communicates with the first left liquid cooling tank 41, and the second left liquid cooling channel 1132 communicates with the second left liquid cooling tank 42. The liquid delivery directions of the first and second left liquid cooling channels 1131 and 1132 are opposite.

[0117] In this embodiment, the pressing mold 11 is provided with a first left inlet 1133, a first left outlet 1134, a second left inlet 1135, and a second left outlet 1136 at the position corresponding to the left cold water portion. In this embodiment, the first left inlet 1133 and the second left outlet 1136 are both located on the side of the left cold water portion away from the second cold water portion. In this embodiment, both the first inlet and the second inlet are equipped with solenoid valves.

[0118] The first left liquid cooling tank 41 is connected to the first left inlet 1133 and the first left outlet 1134. The water outlet of the first left liquid cooling tank 41, the first left inlet 1133, the first left liquid cooling channel 1131, the first left outlet 1134, and the return water end of the first left liquid cooling tank 41 form a first left liquid cooling circuit. The first left liquid cooling circuit cools the rubber material in the left liquid cooling section 113.

[0119] In this embodiment, the second left liquid cooling box 42 is connected to the second left inlet 1135 and the second left outlet 1136, and the water outlet end of the second left liquid cooling box 42, the second left inlet, the second left liquid cooling channel 1132, the second left outlet 1136 and the return water end of the second left liquid cooling box 42 form a second liquid cooling circuit; with the projection on the plane where the pressing mold 11 is located, the conveying direction of the first left liquid cooling circuit in the first left liquid cooling channel 1131 is opposite to the conveying direction of the second left liquid cooling circuit in the second left liquid cooling channel 1132.

[0120] The left liquid cooling device in this embodiment performs liquid cooling on the left liquid cooling part 113 from the rear to the front through the first left liquid cooling channel 1131, and performs liquid cooling on the left liquid cooling part 113 from the front to the rear through the second left liquid cooling channel 1132. The left liquid cooling device performs bidirectional cooling on the left liquid cooling part 113, avoiding the problem of unidirectional liquid cooling and poor liquid cooling effect at the end of the pipeline, thereby improving the stability of the liquid cooling mechanism 4 during use.

[0121] During the use of the temperature-adjustable rubber strip vulcanizing equipment in this embodiment, the density of the condensate transported by the second left liquid cooling channel 1132 can be set to be greater than the density of the condensate transported by the first left liquid cooling channel 1131. The greater the density of the condensate, the stronger the cooling effect. The density of the condensate transported through the second left liquid cooling channel 1132 is larger, which facilitates the neutralization of the temperature at the end of the transport direction of the first left liquid cooling channel 1131, thereby improving the stability of the left liquid cooling device during use.

[0122] In this embodiment, the cross-sectional diameter of the second left liquid cooling channel 1132 is smaller than that of the first left liquid cooling channel 1131, and the second left liquid cooling channel 1132 is located within the first left liquid cooling channel 1131. The second left liquid cooling channel 1132 is disposed within the first left liquid cooling channel 1131, and its cross-sectional width is smaller than that of the first left liquid cooling channel 1131. The outer wall of the second left liquid cooling channel 1132 reduces the cross-sectional area of the first left liquid cooling channel 1131, thereby increasing the liquid cooling pressure and the delivery efficiency of the first left liquid cooling channel 1131.

[0123] Furthermore, the top surface of the second left liquid cooling channel 1132 is connected to the internal top surface of the first left liquid cooling channel 1131; since the bottom end of the pressing mold 11 cools the rubber material, the second left liquid cooling channel 1132 is installed at the internal top of the first left liquid cooling channel 1131. Compared with the second left liquid cooling channel 1132 being set at the center of the first left liquid cooling channel 1131, the condensate flow at the bottom of the first left liquid cooling channel 1131 is increased, and the first left liquid cooling channel 1131 is more efficient in cooling the rubber material at the bottom end of the pressing mold 11.

[0124] In this embodiment, the second left liquid cooling channel 1132 is a metal pipe installed in the first left liquid cooling channel 1131, such as a copper pipe. The second left liquid cooling channel 1132 is a metal pipe with strong heat conduction performance, fast cooling speed, thin pipe wall, which is convenient for the production and assembly of the pressing mold 11, and corrosion-resistant, with strong structural practicality.

[0125] Furthermore, the right liquid cooling device in this embodiment includes a first right liquid cooling tank 43 and a second right liquid cooling tank 44. Two groups of right liquid cooling channels are provided, namely a first right liquid cooling channel and a second right liquid cooling channel. The first right liquid cooling channel communicates with the first right liquid cooling tank 43, and the second right liquid cooling channel communicates with the second right liquid cooling tank 44. The liquid is transported in opposite directions in the first and second right liquid cooling channels. The right and left liquid cooling devices have substantially the same structure and are not described in detail here.

[0126] Combine Figure 11 , the second implementation structure of the left liquid cooling unit in the present invention is as follows:

[0127] In this embodiment, the left liquid cooling unit 113a includes multiple groups of left liquid cooling channels. These channels extend parallel to each other and are interconnected. Multiple groups of left liquid cooling channels can be provided to increase the cooling area of the left liquid cooling channels, thereby further enhancing the practicality of the liquid cooling mechanism 4. The second embodiment of the right liquid cooling unit in this embodiment is identical to the second embodiment of the left liquid cooling unit and will not be further described here.

[0128] Furthermore, in this embodiment, multiple groups of first left liquid cooling channels 1131a and second left liquid cooling channels 1132a are provided, with each group of first left liquid cooling channels 1131a corresponding one-to-one with each group of second left liquid cooling channels 1132a. In this embodiment, the cross-sectional diameter of the second left liquid cooling channels 1132a is smaller than that of the first left liquid cooling channels 1131a, and the second left liquid cooling channels 1132a are located within the first left liquid cooling channels 1131a. The second left liquid cooling channel 1132a is arranged in the first left liquid cooling channel 1131a. The cross-sectional width of the second left liquid cooling channel 1132a is smaller than the cross-sectional width of the first left liquid cooling channel 1131a. The second left liquid cooling channel 1132a is located in the first left liquid cooling channel 1131a. The outer wall of the second left liquid cooling channel 1132a reduces the cross-sectional area of the first left liquid cooling channel 1131, thereby increasing the liquid cooling pressure of the first left liquid cooling channel 1131a and improving the delivery efficiency of the first left liquid cooling channel 1131a.

[0129] Several first left liquid cooling channels 1131a are interconnected, and several first left liquid cooling channels 1131a share the first left inlet 1133a and the first left outlet 1134a, which is convenient for connecting and installing pipes and making the structure more streamlined; several second left liquid cooling channels 1132a are interconnected, and several second left liquid cooling channels 1132a share the second left inlet 1135 and the second left outlet 1136, which is convenient for connecting and installing pipes and making the structure more streamlined.

[0130] Working principle of the present invention:

[0131] The temperature-adjustable rubber strip vulcanizing equipment in this embodiment is used to continuously vulcanize rubber strip segments. This embodiment is described by continuously processing the first rubber material, the second rubber material, and the second rubber strip.

[0132] 1. The feeding mechanism 2 transports and feeds the first rubber material and the second rubber material.

[0133] The first adhesive material includes a first head portion, a first middle portion, and a first tail portion. The second adhesive material includes a second head portion, a second middle portion, and a second tail portion. In this embodiment, the second head portion is connected to the first tail portion.

[0134] When the temperature-adjustable rubber strip vulcanizing equipment is vulcanizing and producing the first rubber material, along the production line direction of the temperature-adjustable rubber strip vulcanizing equipment conveying the material, the first head corresponds to the left liquid cooling part 113, the first middle part corresponds to the fixing part 111 of the pressing mold 11, and the connection between the first tail and the second head corresponds to the right liquid cooling part 112.

[0135] 2. The vulcanizing machine body vulcanizes the first rubber material to form a first rubber strip.

[0136] The vulcanization temperature of the left vulcanization area is the same as that of the middle vulcanization area, and the left liquid cooling device is not turned on; the vulcanization temperature of the right liquid cooling area is lowered so that the temperature of the right vulcanization area reaches the set half-vulcanization temperature.

[0137] At this time, the first driving component 164 in the adjusting device 16 drives the first rotating seat 162 and the second rotating seat 163 to be roughly flush with the supporting seat 161, so that the first heating component 151, the left heating component 152 and the right heating component 153 heat the first rubber material synchronously.

[0138] The upper driving device 112 in the upper mold mechanism 1a drives the pressing mold 11 to move downward, thereby pressing the first rubber material downward to form the rubber material.

[0139] The right liquid cooling device is started to cool the rubber material in the right vulcanization area so that the temperature of the right vulcanization area reaches the set semi-vulcanization temperature, so that the connection between the first tail and the second head is semi-vulcanized.

[0140] 3. The feeding mechanism 2 conveys the second rubber material and the third rubber material, the vulcanizer body 1 vulcanizes the second rubber material to form the second rubber material, and the unloading mechanism 3 outputs the first rubber strip.

[0141] The third rubber material includes a third head portion, a third middle portion and a third tail portion which are connected in sequence.

[0142] 1. The connection between the semi-vulcanized first tail and the second head moves to the left vulcanization area, the second middle part of the second rubber material corresponds to the middle vulcanization area, and the connection between the second tail and the third head of the third rubber material is located in the right vulcanization area.

[0143] 2. Start the left liquid cooling device and the right liquid cooling device. The left liquid cooling device performs liquid cooling on the rubber material in the left vulcanization area. When the temperature of the left vulcanization area reaches the set semi-vulcanization temperature, the connection between the first tail and the second head is semi-vulcanized for the second time, that is, the connection between the first tail and the second head is fully vulcanized in the left vulcanization area.

[0144] The right liquid cooling device performs liquid cooling on the rubber material in the right vulcanization area so that the temperature of the right vulcanization area reaches the set semi-vulcanization temperature, so that the connection between the second tail and the third head forms a semi-vulcanization.

[0145] 3. If the second rubber compound is provided in several groups and the several second rubber compounds are connected in sequence, the above two steps are repeated to improve the stability of the continuous vulcanization connection of the second rubber compounds.

[0146] 4. During the temperature adjustment process of the left vulcanizing area and the right vulcanizing area, the left heating component 152 and the right heating component 153 in the heating device 15 can also be adjusted by turning downward, thereby further improving the practicality of the temperature-adjustable rubber strip vulcanizing equipment.

[0147] The first driving assembly 164 drives the first slider 1642 to move downward along the first guide rail 1641, and the first slider 1642 drives the first rotating rod 1643 to rotate the first rotating seat 162 downward around one side of the support seat 161, and the first slider 1642 drives the second rotating rod 1651 to rotate the second rotating seat 163 downward around the other side of the support seat 161; the first rotating seat 162 drives the left heating assembly 152 away from the molding shell 14, so that the left heating assembly 152 can reduce the heating temperature of the rubber material in the left vulcanization area and cool the rubber material in the left vulcanization area in advance, and the second rotating seat 163 drives the right heating assembly 153 away from the molding shell 14, so that the right heating assembly 153 can reduce the heating temperature of the rubber material in the right and left vulcanization areas and cool the rubber material in the right vulcanization area in advance; this structure avoids overheating of the left and right vulcanization areas, and the structure is highly practical.

[0148] Fourth, the unloading mechanism 3 outputs the second rubber material, and the vulcanizing equipment vulcanizes the third rubber material to form the third rubber material.

[0149] Start the left liquid cooling device and close the right liquid cooling device. The left liquid cooling device performs liquid cooling on the rubber material in the left vulcanization area. The temperature of the left vulcanization area reaches the set semi-vulcanization temperature. The connection between the second tail and the third head is semi-vulcanized for the second time, that is, the connection between the second tail and the third head is fully vulcanized in the left vulcanization area.

[0150] The vulcanization temperature of the right vulcanization area is the same as that of the middle vulcanization area, and the right liquid cooling device is not turned on; the upper driving device 112 in the upper mold mechanism 1a drives the pressing mold 11 to move downward, thereby pressing the third rubber material downward to form the end of the continuous rubber strip.

[0151] This completes the process of continuously vulcanizing the rubber material of the temperature-adjustable rubber strip vulcanizing equipment of the preferred embodiment.

[0152] The heating components in this embodiment are generally of the type commonly used in vulcanizers, such as electric heating wire heating, and are not described in detail here. Furthermore, the first and second drive components, the lifting device, and the like in this embodiment can all be driven by cylinders, screw motors, and other commonly used drive structures in industrial production, and are not described in detail here.

[0153] In the actual application process of the liquid cooling mechanism 4 in this embodiment, water cooling, liquid helium, electronic fluoride liquid or mixed condensate with other different densities are preferably used. In addition, the liquid cooling mechanism 4 in this embodiment can also use gas cooling, such as ammonia, etc., which is specifically selected according to user needs.

[0154] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
