Description

Technical Field

[0001] The present invention relates to the technical field of raw material mixing equipment, and more specifically, to a raw material mixing equipment for the production and processing of rubber conveyor belts. Background Art

[0002] A rubber conveyor belt is a conveyor belt made of rubber, and a variety of rubbers and materials are mixed with each other as the main raw materials for production. The existing raw material mixing method usually uses a mixing equipment to extrude and knead the raw materials. However, during the mixing process, the extrusion roller distance of the mixing equipment for the raw materials needs to be manually adjusted, which is not convenient to operate and is prone to adjustment errors, resulting in uneven mixing of the raw materials and affecting the use effect of the raw materials. At the same time, the mixing structure of the existing mixing equipment is single, resulting in a longer time required for raw material mixing, thereby reducing the mixing speed and affecting the production efficiency. For this reason, we propose a raw material mixing equipment for the production and processing of rubber conveyor belts. Summary of the Invention

[0037] Please refer to Figures 1 - 8 As shown, a raw material mixing device for the production and processing of rubber conveyor belts includes two symmetrically arranged support frames 1. A connecting cross beam 101 is fixedly installed on the lower part of the outer surface of the side close to each other between the two support frames 1. A tray 102 is placed and fixed on the upper surface of the connecting cross beam 101. A number of guiding partition plates 103 are fixedly installed at intervals in the middle of the inner surface of the support frame 1. Guiding blocks 2 are movably installed at both ends of the inner surface at intervals between the a number of guiding partition plates 103. Guiding grooves 104 are respectively formed through the middle of the upper surfaces of the a number of guiding partition plates 103. The middle parts of the upper and lower surfaces of the guiding blocks 2 at the same end are both convexly arranged and embedded in the guiding grooves 104 and fixedly connected to each other. An assembly port 201 is formed through the middle of one side of the outer surface of the guiding block 2;

[0038] The entire device is supported by the support frame 1. The support frames 1 are connected in series by the connecting cross beam 101 to ensure its stability during use and support the tray 102. The raw materials during the mixing process are supported by the tray 102. The guiding partition plates 103 can separate the guiding blocks 2. The guiding blocks 2 can move and adjust along the guiding grooves 104. The assembly port 201 facilitates the installation of the first mixing roller group 5, the second mixing roller group 6 and the third mixing roller group 7 on the guiding blocks 2.

[0039] On the upper and lower parts of the inner surface of the support frame 1, guide rods 3 are fixedly provided. At both ends of the outer surface of the guide rod 3, guide plates 301 are movably sleeved and installed. The upper surfaces of the guide plates 301 located on the lower part of the inner surface of the support frame 1 are fixedly connected to the lower surfaces of the guide blocks 2, and the lower surfaces of the guide plates 301 located on the upper part of the inner surface of the support frame 1 are fixedly connected to the upper surfaces of the guide blocks 2. In the middle of the outer surfaces of the guide plates 301 on the closer side to each other, fixing rings 304 are fixedly provided. On the middle parts of both sides of the outer surface of the fixing ring 304, scissor-type telescopic frames 302 are movably installed together. On the movable joints on the closer side to each other between the outer surfaces of the scissor-type telescopic frames 302, adjusting screw blocks 303 are fixedly installed together. In the middle of the inner bottom surface of the support frame 1, a first motor 4 is fixedly installed. Above the output end of the first motor 4, an adjusting connecting rod 401 is fixedly installed. At both ends of the adjusting connecting rod 401, bidirectional screw rods 402 are fixedly provided;

[0040] The other ends of the bidirectional screw rods 402 penetrate through the middle parts of the outer surfaces of the adjusting screw blocks 303 and the guide rods 3 and extend outwards. On the inner surface of the penetrated part of the adjusting screw block 303, internal threads matching the bidirectional screw rods 402 are provided. On the lower surface of the bidirectional screw rod 402 at the lower end of the adjusting connecting rod 401, it is fixedly installed and connected to the output end of the first motor 4;

[0041] By controlling the first motor 4 to rotate the bidirectional screw rod 402 and the adjusting connecting rod 401 clockwise and counterclockwise, when the bidirectional screw rod 402 rotates clockwise, the adjusting screw blocks 303 sleeved on its surface can be controlled to move closer and close together. Through the close movement of the adjusting screw blocks 303, the scissor-type telescopic frame 302 can be driven to fold and close. Through the folding and closing of the scissor-type telescopic frame 302, the guide plates 301 are pushed to move away from each other along the guide rods 3. When the bidirectional screw rod 402 rotates counterclockwise, the adjusting screw blocks 303 sleeved on its surface can be controlled to move away and expand. Through the away and expand movement of the adjusting screw blocks 303, the scissor-type telescopic frame 302 can be driven to contract and close. Through the contraction and closing of the scissor-type telescopic frame 302, the guide plates 301 are driven to move closer to each other along the guide rods 3. Since the guide plates 301 are connected to the guide blocks 2, the guide blocks 2 can be synchronously driven to move and adjust through the movement of the guide plates 301, achieving the effect of adjusting the roller distance between the first mixing roller group 5, the second mixing roller group 6, and the third mixing roller group 7.

[0042] In the middle of the closer side to each other between the two support frames 1, a second mixing roller group 6 is movably installed. Above the second mixing roller group 6, a first mixing roller group 5 is movably installed. Below the second mixing roller group 6, a third mixing roller group 7 is movably installed;

[0043] At the middle parts of both ends of the first mixing roller group 5, the second mixing roller group 6 and the third mixing roller group 7, convex shafts are provided and penetrate through the assembly port 201 to extend outside. The first mixing roller group 5 includes two symmetrically arranged first mixing rollers, and the first mixing rollers are arranged in a smooth columnar shape. The second mixing roller group 6 includes two symmetrically arranged second mixing rollers, and the outer surface of the second mixing rollers is funnel-shaped from both ends to the middle. First mixing teeth 601 are fixedly arranged at the middle of the outer surface of the second mixing rollers in a staggered manner. The third mixing roller group 7 includes two symmetrically arranged third mixing rollers, and the outer surface of the third mixing rollers is funnel-shaped from the middle to both ends. Second mixing teeth 701 are fixedly arranged at both ends of the outer surface of the third mixing rollers in a staggered manner;

[0044] Lower parts of the outer surfaces on the far sides between the two sets of support frames 1 are both provided with lifting plate assemblies 9. Second motors 10 are fixedly installed on the upper surfaces of the lifting plate assemblies 9. The lifting plate assembly 9 includes a fixed plate and a movable plate. The fixed plate is fixedly installed and connected to the lower part on one side of the outer surface of the support frame 1. Electric push rods 901 are fixedly installed on both sides of the upper surface of the fixed plate. The movable plate is fixedly installed on the upper surface of the electric push rod 901. A fixed sleeve 902 is fixedly installed on the upper surface of the movable plate, and the fixed sleeve 902 is sleeved on the outer surface of the second motor 10;

[0045] Through the telescopic movement of the electric push rod 901, the movable plate in the lifting plate assembly 9 is driven to move up and down, so that the second motor 10 is driven to move up and down to adjust the position by the up and down movement of the movable plate. The second motor 10 is locked and fixed by the fixed sleeve 902, and the first mixing roller group 5, the second mixing roller group 6 and the third mixing roller group 7 are driven to perform mixing operations by the operation of the second motor 10.

[0046] Drive gears 8 are fixedly installed at the output ends of the second motors 10 and at the ends extending outside of the first mixing roller group 5, the second mixing roller group 6 and the third mixing roller group 7. A drive belt 11 is jointly engaged and sleeved on the outer surfaces of the drive gears 8 arranged at the output end of one of the second motors 10 and at the rear ends extending outside of the first mixing roller group 5, the second mixing roller group 6 and the third mixing roller group 7. A drive belt 11 is jointly engaged and sleeved on the outer surfaces of the drive gears 8 arranged at the output end of the other second motor 10 and at the front ends extending outside of the first mixing roller group 5, the second mixing roller group 6 and the third mixing roller group 7;

[0047] The second motor 10 is operated to control the transmission gear 8 arranged at its output end to rotate, and the transmission gear 8 arranged at the output end of the second motor 10 is rotated to drive the transmission belt 11 to operate, so that the transmission operation of the transmission belt 11 drives the transmission gear 8 arranged at the ends of the first mixing roller group 5, the second mixing roller group 6 and the third mixing roller group 7 to rotate, and the first mixing roller group 5, the second mixing roller group 6 and the third mixing roller group 7 are mutually engaged and rotated when the two ends are staggered and connected, so as to realize the extrusion mixing of the raw materials.

[0048] A limit lever 105 is fixedly installed above the middle of the upper surface of the lifting plate assembly 9, one end of the limit lever 105 is fixedly connected to the outer surface of the support frame 1, and the outer surface of the limit lever 105 is in limit contact with the outer surface of the transmission belt 11;

[0049] By limiting the outer surface of the limit lever 105 in contact with the outer surface of the transmission belt 11, the tension of the transmission belt 11 can be maintained during position adjustment, thereby ensuring that it stably drives the first mixing roller group 5, the second mixing roller group 6 and the third mixing roller group 7 to operate.

[0050] An integrated control computer 12 is fixedly installed at the front middle of the outer surface of one of the support frames 1. The internal configuration of the integrated control computer 12 includes a database, an instruction receiving module, an instruction analyzing module and an execution module;

[0051] The database is used to store the mixing roller distance values ​​required for uniform mixing of various types of raw material ratio data, and to form a preset mixing instruction with the various types of raw material ratio data and the corresponding mixing roller distance values;

[0052] The specific analysis is as follows: each type of raw material is set as A, B, C, ..., and substituted into the formula P = A × ∞1 + B × ∞2 + C × ∞3 to obtain the preset raw material mixing ratio index P, ∞1, ∞2, ∞3 are expressed as the proportion coefficients of each type of raw material, and different preset raw material ratio indexes P, P1, P2, ... can be calculated according to different proportion coefficients. Based on the preset raw material ratio indexes P, P1, P2, ..., the mixing operator presets the mixing roller distance required for uniform mixing, and the mixing roller distance value is set as GJ1, GJ2, ...;

[0053] The instruction receiving module is used to receive the proportion data of various types of raw materials input by the mixing personnel, and integrate the proportion data of various types of raw materials to obtain the raw material ratio data, and form a mixing instruction to be transmitted to the instruction analysis module;

[0054] The specific analysis is as follows: The proportion data of various types of raw materials are input by the mixing operator, and substituted into the formula P' = A×∞1' + B×∞2' + C×∞3' to obtain the raw material mixing ratio index P'. ∞1', ∞2', and ∞3' represent the proportion coefficients of the input various types of raw materials, and the raw material mixing ratio index P' is transmitted to the instruction analysis module;

[0055] The instruction analysis module is used to match the received mixing instruction with the preset mixing instruction, and obtain the corresponding adjustment instruction based on the matching result and transmit it to the execution module;

[0056] The specific analysis is as follows: Based on the received raw material mixing ratio index P' and the preset raw material mixing ratio indexes P, P1, P2,... for matching, if the matching is successful, the corresponding mixing roller distance values GJ1, GJ2,... are obtained, and the corresponding adjustment instructions are generated based on the roller distance values. The adjustment instructions specifically include the operation ranges corresponding to each adjustment structure adjusted to this roller distance;

[0057] The execution module is wirelessly connected to the first motor 4 and the lifting plate assembly 9, and controls the first motor 4 and the lifting plate assembly 9 to perform corresponding adjustment operations based on the received adjustment instruction to complete the adjustment of the mixing roller distance;

[0058] The specific analysis is as follows: Based on the roller distance value corresponding to the adjustment instruction, the execution module first controls the first motor 4 and the lifting plate assembly 9 to adjust the mixing roller distance to the original value for resetting. After the reset is completed, the corresponding roller distance adjustment is performed according to the adjustment instruction.

[0059] When the present invention is in use, first, the proportion data of various types of mixed raw materials are input by the mixing operator. After being calculated by the integrated control computer 12, the roller distance required for the corresponding raw materials to be mixed evenly is obtained. At this time, the integrated control computer 12 can control the first motor 4 to start, start to rotate in the corresponding clockwise direction according to the adjustment requirement, and control the bidirectional screw 402 and the adjustment link 401 to rotate clockwise and counterclockwise;

[0060] When the first motor 4 controls the bidirectional screw 402 to rotate clockwise, it can drive the adjustment screw block 303 to move closer to each other along the bidirectional screw 402, thereby squeezing the scissor expansion frame 302 and driving the scissor expansion frame 302 to fold and close. At this time, both ends of the scissor expansion frame 302 will extend in opposite directions, thereby pushing the guide plate 301 to move away from each other along the guide rod 3. Since the guide plate 301 is connected to the guide block 2, the movement of the guide plate 301 can be used to synchronously drive the guide block 2 to move and adjust, achieving the effect of increasing the roller distance between the first mixing roller group 5, the second mixing roller group 6, and the third mixing roller group 7 until it is adjusted to the required roller distance;

[0061] When the first motor 4 controls the bidirectional screw 402 to rotate counterclockwise, it can drive the adjusting screw block 303 to move away from each other along the bidirectional screw 402, so as to stretch the scissor expansion frame 302 and drive the scissor expansion frame 302 to expand. At this time, both ends of the scissor expansion frame 302 will contract simultaneously, thereby driving the guide plate 301 to move closer to each other along the guide rod 3. Since the guide plate 301 is connected to the guide block 2, the movement of the guide plate 301 can synchronously drive the guide block 2 to move and adjust, achieving the effect of reducing the roll distance between the first mixing roll group 5, the second mixing roll group 6 and the third mixing roll group 7 until it is adjusted to the required roll distance;

[0062] Secondly, during the process of adjusting the roll distance between the first mixing roll group 5, the second mixing roll group 6 and the third mixing roll group 7, when the roll distance is in the contracted state, the integrated control computer 12 can control the electric push rod 901 to contract and operate. At this time, the movable plate in the lifting plate assembly 9 will synchronously descend with the contraction of the electric push rod 901, thereby driving the second motor 10 to descend. Since the distance between the first mixing roll group 5, the second mixing roll group 6, the third mixing roll group 7 and the transmission gear 8 provided at the end of the second motor 10 will decrease when the roll distance contracts, the transmission belt 11 will become loose. At this time, the descent of the second motor 10 can increase the distance between the transmission gear 8 at its output end and the first mixing roll group 5, the second mixing roll group 6 and the third mixing roll group 7, thereby driving the transmission belt 11 to stretch and maintain its tension to ensure that the second motor 10 can drive the first mixing roll group 5, the second mixing roll group 6 and the third mixing roll group 7 to operate stably;

[0063] When the roll distance is in the expanded state, the integrated control computer 12 can control the electric push rod 901 to extend and operate. At this time, the movable plate in the lifting plate assembly 9 will synchronously rise with the extension of the electric push rod 901, thereby driving the second motor 10 to rise. Since the distance between the first mixing roll group 5, the second mixing roll group 6, the third mixing roll group 7 and the transmission gear 8 provided at the end of the second motor 10 will increase when the roll distance expands, the transmission belt 11 will be stretched. At this time, the rise of the second motor 10 can reduce the distance between the transmission gear 8 at its output end and the first mixing roll group 5, the second mixing roll group 6 and the third mixing roll group 7, thereby driving the transmission belt 11 to reset and maintain its tension to ensure that the second motor 10 can drive the first mixing roll group 5, the second mixing roll group 6 and the third mixing roll group 7 to operate stably and ensure the normal progress of the mixing operation of the raw materials;

[0064] After the roll gap adjustment is completed, the second motor 10 can be started to operate and control the rotation of the transmission gear 8 provided at its output end. The rotation of the transmission gear 8 provided at the output end of the second motor 10 drives the transmission belt 11 to run. Thus, the rotation of the transmission belt 11 drives the rotation of the transmission gears 8 provided at the ends of the first mixing roll group 5, the second mixing roll group 6, and the third mixing roll group 7. When they are staggered and connected at both ends, the first mixing roll group 5, the second mixing roll group 6, and the third mixing roll group 7 are engaged and rotated with each other, realizing the extrusion and mixing of raw materials.
