Description

Technical Field

[0001] This utility model relates to the field of conveyor belt manufacturing equipment technology, specifically to a simple mold for conveyor belts. Background Technology

[0002] Conveyor belt molds are key equipment used for conveyor belt splice pressing, pattern forming, and other processing. Through the pressing action of the upper and lower molds, the conveyor belt material is tightly bonded, ensuring the strength and durability of the conveyor belt. In small and medium-sized production scenarios, simple molds are widely used due to their simple structure and convenient operation.

[0003] According to a disclosed wear-resistant conveyor belt forming mold (publication number: CN214773337U), it includes: an upper template, two fixing blocks fixedly installed on the top surface of the upper template, a fixing groove opened on the top of the fixing block, a through hole opened on one side of the fixing block, two slots opened on the side of the two fixing blocks close to each other, a vertical plate fixed inside the fixing groove by a locking member, and a through groove opened on one side of the vertical plate. This wear-resistant conveyor belt forming mold, by setting the fixing blocks, fixing grooves, vertical plates, through grooves, through holes, slots, locking rods, locking blocks, springs and pressure plates, can complete the quick disassembly and fixing of the upper template, so that when the upper template is damaged, it is convenient to repair or replace it.

[0004] In the above application, the upper template can be quickly disassembled and assembled by the cooperation of the fixing block, vertical plate and locking parts, which facilitates mold maintenance and replacement. However, there are problems such as uneven force on the mold during the pressing process, which can easily lead to poor conveyor belt forming quality, lack of automatic lubrication mechanism leading to rapid wear of parts, and large rigid impact of pressing action. Therefore, we propose a simple mold for conveyor belts. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a simple mold for conveyor belts, which solves the problems of uneven pressing force, lack of automatic lubrication, and large impact in the prior art.

[0006] According to one aspect, at least one embodiment of the present invention provides a simple mold for conveyor belts, comprising: a base, a mold seat provided on the top of the base, a lower mold fixedly connected to the top of the mold seat, an upper mold provided on the top of the lower mold, a device housing fixedly connected to the top of the base, and a pressing device provided inside the device housing; The pressing device includes a support rod, the bottom end of which is fixedly connected to the top of the base, and the top end of which is fixedly connected to the bottom of the upper mold. The circumferential surface of the support rod passes through and is slidably connected to the bottom of the mold base. A transmission roller is fixedly connected to the bottom of the mold base. A movable cam is slidably connected to the top of the base. A wave block is fixedly connected to the side of the movable cam. The bottom of the wave block is slidably connected to the top of the base. A telescopic rod is fixedly connected to the top of the base. The telescopic end of the telescopic rod is fixedly connected to the side of the wave block. A spring is provided on the circumferential surface of the support rod.

[0007] For example, in at least one embodiment of this utility model, a simple mold for conveyor belts is provided, which further includes: the circumferential surface of the transmission roller is in contact with the top of the moving cam and the wave block; the number of the support rods is four, and they are symmetrical about each other along the vertical central axis of the mold base; the transmission roller is in contact with the moving cam and the wave block to ensure that the power is stably transmitted to the mold base; the four symmetrical support rods make the mold base bear the force evenly, avoid tilting during pressing, and improve the flatness and accuracy of the conveyor belt pressing.

[0008] The top end of the spring is fixedly connected to the bottom of the mold base, and the bottom end of the spring is fixedly connected to the top of the base. The spring connects the mold base and the base. The spring is always in a stretched state, and its continuous elastic force makes the transmission roller tightly fit against the surface of the moving cam and the wave block, ensuring that there is no gap between them and ensuring that the power transmission is uninterrupted.

[0009] A stabilizing plate is fixedly connected to the side of the telescopic rod, and the bottom of the stabilizing plate is fixedly connected to the top of the base. The stabilizing plate reinforces the connection between the telescopic rod and the base, prevents the telescopic rod from shaking when it extends or retracts, ensures that the moving cam and wave block slide smoothly, ensures the precise action of the pressing device, and improves the stability of operation.

[0010] The length of the displacement trajectory of the telescopic rod's telescopic end is equal to the sum of the lengths of the moving cam and the wave block. A limiting shell is fixedly connected to the top of the base. The side of the moving cam is in contact with the inner wall side of the limiting shell. The displacement of the telescopic rod matches the lengths of the moving cam and the wave block, ensuring that they fully participate in the transmission. The limiting shell restricts the offset of the moving cam, avoids transmission misalignment, ensures stable pressing rhythm, and improves the reliability of mold operation.

[0011] According to another aspect, at least one embodiment of the present invention also provides a simple mold for conveyor belts, comprising: a lubrication device, the lubrication device including an oil tank, the bottom of the oil tank being fixedly connected to the top of a base, an oil supply pipe being fixedly connected to the side of the oil tank, one end of the oil supply pipe being fixedly connected to the side of a limiting shell, a through groove being provided on the side of the limiting shell, a transmission rod being fixedly connected to the side of a corrugated block, a rack being fixedly connected to the top of the transmission rod, a support plate being fixedly connected to the top of the base, a rotating shaft being rotatably connected to the inner circumference of the support plate, a gear being fixedly connected to one end of the rotating shaft, a transmission wheel being fixedly connected to the other end of the transmission rod, and a pressure rod being rotatably connected to the side of the transmission wheel.

[0012] For example, in a simple mold for conveyor belts provided in at least one embodiment of the present invention, the rack and gear mesh with each other, the circumferential surface of the transmission rod is slidably connected to the inner wall of the through groove, the meshing of the rack and gear realizes power conversion, ensures that the lubrication device and the pressing device operate synchronously, the transmission rod slides in the through groove, restricts its movement trajectory, avoids the rack and gear from disengaging, and ensures the smooth operation of the lubrication mechanism.

[0013] One end of the pressure rod is rotatably connected to a squeezing block, and the side of the squeezing block is slidably connected to the inner wall of the side of the oil tank. When the squeezing block slides in the oil tank, it squeezes the lubricating oil, so that the lubricating oil is accurately delivered to the friction parts in the limiting shell through the oil supply pipe, thereby achieving automatic lubrication, reducing component wear, and improving the smooth operation of the device.

[0014] The side of the extrusion block is provided with a sealing ring, which is fixedly connected to the inner wall of the oil tank. The sealing ring enhances the sealing between the extrusion block and the oil tank, prevents lubricating oil leakage, ensures stable lubrication pressure, ensures full lubrication effect, and avoids resource waste.

[0015] The number of support plates is set to two, and they are symmetrical to each other along the vertical central axis of the rotating shaft. The width of the rack is equal to the length of the through groove. The two symmetrical support plates firmly support the rotating shaft to prevent it from shaking when rotating, ensuring accurate meshing of the gear and rack. The width of the rack matches the through groove to avoid the transmission rod from deviating, and further ensuring the stable power transmission of the lubrication device.

[0016] The beneficial effects of the embodiments of this utility model are as follows: 1. In this utility model, the conveyor belt is stably and accurately pressed through a pressing device. The telescopic rod drives the moving cam and the wave block to slide. The transmission roller converts the displacement of the cam and the wave block into the up and down movement of the mold seat. When the transmission roller is pushed, a wave-like pressing action is generated. The pressing process of the mold seat and the lower mold presents a periodic rhythm of gradual rise, hold, and gradual fall, rather than the traditional instantaneous rigid pressing. Four symmetrical support rods ensure that the mold seat is subjected to balanced force. The spring buffers the impact force during pressing and assists in the reset after pressing, avoiding mold tilting or excessive wear. This effectively improves the flatness and forming quality of the conveyor belt pressing, while simplifying the complex transmission structure of traditional molds and reducing the difficulty of operation.

[0017] 2. In this utility model, automatic lubrication is achieved through the linkage of the lubrication device and the pressing device. The wave block drives the transmission rod to move, and the pressure rod is driven by the meshing of the rack and gear, so that the extrusion block slides in the oil tank. Lubricating oil is delivered to the friction parts in the limiting shell through the oil supply pipe. The sealing ring ensures the seal and avoids leakage. The symmetrical support plate and the through groove limit ensure the transmission stability, reduce wear between parts, extend the service life of the device, and eliminate the manual lubrication step, thereby improving the work efficiency.

[0027] like Figures 1-5 The present invention illustrates a simple mold for conveyor belts in one embodiment of the present invention, comprising: a base 1, a mold base 2 on the top of the base 1, a lower mold 3 fixedly connected to the top of the mold base 2, an upper mold 4 on the top of the lower mold 3, a device housing 5 fixedly connected to the top of the base 1, and a pressing device 6 inside the device housing 5. The pressing device 6 includes a support rod 601. The bottom end of the support rod 601 is fixedly connected to the top of the base 1, and the top end of the support rod 601 is fixedly connected to the bottom of the upper mold 4. The circumferential surface of the support rod 601 is slidably connected to the bottom of the mold base 2. A transmission roller 602 is fixedly connected to the bottom of the mold base 2. A moving cam 603 is slidably connected to the top of the base 1. A wave block 604 is fixedly connected to the side of the moving cam 603. The bottom of the wave block 604 is slidably connected to the top of the base 1. A telescopic rod 605 is fixedly connected to the top of the base 1. The telescopic end of the telescopic rod 605 is fixedly connected to the side of the wave block 604. A spring 606 is provided on the circumferential surface of the support rod 601.

[0028] In some examples, the circumferential surface of the drive roller 602 contacts the top of the moving cam 603 and the wave block 604. There are four support rods 601, which are symmetrical about each other along the vertical central axis of the mold base 2. The drive roller 602 contacts the moving cam 603 and the wave block 604 to ensure that the power is stably transmitted to the mold base 2. The four symmetrical support rods 601 make the mold base 2 bear the force evenly, avoid tilting during pressing, and improve the flatness and accuracy of the conveyor belt pressing. The top end of the spring 606 is fixedly connected to the bottom of the mold base 2, and the bottom end of the spring 606 is fixedly connected to the top of the base 1. The spring 606 is always in a stretched state, and its continuous elastic force makes the transmission roller 602 fit tightly against the surface of the moving cam 603 and the wave block 604, ensuring that there is no gap between them and ensuring that the power transmission is uninterrupted. A stabilizing plate 607 is fixedly connected to the side of the telescopic rod 605. The bottom of the stabilizing plate 607 is fixedly connected to the top of the base 1. The stabilizing plate 607 reinforces the connection between the telescopic rod 605 and the base 1, prevents the telescopic rod 605 from shaking when it extends or retracts, ensures that the moving cam 603 and the wave block 604 slide smoothly, ensures the precise action of the pressing device 6, and improves the stability of operation. The length of the displacement trajectory of the telescopic rod 605 is equal to the sum of the lengths of the moving cam 603 and the wave block 604. The top of the base 1 is fixedly connected to the limiting shell 608. The side of the moving cam 603 is in contact with the inner wall side of the limiting shell 608. The displacement of the telescopic rod 605 matches the lengths of the moving cam 603 and the wave block 604, ensuring that it fully participates in the transmission. The limiting shell 608 restricts the offset of the moving cam 603, avoids transmission misalignment, ensures stable pressing rhythm, and improves the reliability of mold operation.

[0029] For example, such as Figures 1-5 During operation, the telescopic rod 605 is activated, causing the wave block 604 to slide on the base 1. The movable cam 603, which is fixedly connected to the wave block 604, moves synchronously and maintains a stable trajectory under the constraint of the limiting shell 608. The transmission roller 602 at the bottom of the mold base 2 contacts the top of the movable cam 603 and the wave block 604. As the movable cam 603 and the wave block 604 slide, their undulating structure pushes the transmission roller 602 up and down, thereby causing the mold base 2 to rise and fall vertically along the four symmetrical support rods 601. When the mold base 2... During the upward movement, the lower mold 3 moves closer to the upper mold 4 to press the conveyor belt. As the moving cam 603 and the wave block 604 continue to slide, one pressing cycle is completed. The stabilizing plate 607 reinforces the telescopic rod 605 throughout the process to prevent it from shaking and affecting the transmission stability. The spring 606 on the circumferential surface of the support rod 601 is always in a stretched state. Its continuous elasticity keeps the transmission roller 602 tightly attached to the surface of the moving cam 603 and the wave block 604, ensuring that there is no gap between them and that the power transmission is uninterrupted.

[0030] like Figures 1-5This illustration shows a simplified mold for conveyor belts in another embodiment of the present invention, comprising: a lubrication device 7, the lubrication device 7 including an oil tank 701, the bottom of the oil tank 701 being fixedly connected to the top of the base 1, an oil supply pipe 702 being fixedly connected to the side of the oil tank 701, one end of the oil supply pipe 702 being fixedly connected to the side of the limiting shell 608, a through groove 703 being provided on the side of the limiting shell 608, a transmission rod 704 being fixedly connected to the side of the wave block 604, a rack 705 being fixedly connected to the top of the transmission rod 704, a support plate 706 being fixedly connected to the top of the base 1, a rotating shaft 707 being rotatably connected to the inner circumference of the support plate 706, a gear 708 being fixedly connected to one end of the rotating shaft 707, a transmission wheel 709 being fixedly connected to the other end of the transmission rod 704, and a pressure rod 710 being rotatably connected to the side of the transmission wheel 709.

[0031] In some examples, rack 705 and gear 708 mesh with each other, and the circumferential surface of transmission rod 704 is slidably connected to the inner wall of through groove 703. The meshing of rack 705 and gear 708 realizes power conversion, ensuring that lubrication device 7 and pressing device 6 operate synchronously. Transmission rod 704 slides in through groove 703, restricting its movement trajectory, preventing rack 705 and gear 708 from disengaging, and ensuring smooth operation of lubrication mechanism. One end of the pressure rod 710 is rotatably connected to the extrusion block 711. The side of the extrusion block 711 is slidably connected to the inner wall of the side of the oil tank 701. When the extrusion block 711 slides in the oil tank 701, it extrudes the lubricating oil, so that the lubricating oil is accurately delivered to the friction part in the limiting shell 608 through the oil delivery pipe 702, thereby achieving automatic lubrication, reducing component wear, and improving the smooth operation of the device. A sealing ring is provided on the side of the extrusion block 711. The side of the sealing ring is fixedly connected to the inner wall of the oil tank 701. The sealing ring enhances the sealing between the extrusion block 711 and the oil tank 701, prevents lubricating oil leakage, ensures stable lubrication pressure, ensures full lubrication effect, and avoids resource waste.

[0032] There are two support plates 706, which are symmetrical to each other along the vertical central axis of the rotating shaft 707. The width of the rack 705 is equal to the length of the through groove 703. The two symmetrical support plates 706 firmly support the rotating shaft 707 to prevent it from shaking when rotating, ensuring that the gear 708 and the rack 705 mesh accurately. The width of the rack 705 matches the through groove 703 to prevent the transmission rod 704 from deviating, further ensuring the stable power transmission of the lubrication device 7.

[0033] For example, such as Figures 1-5When the wave block 604 slides with the telescopic rod 605, the transmission rod 704 on its side moves synchronously along the through groove 703 of the limiting shell 608. The rack 705 at the top of the transmission rod 704 meshes with the gear 708 on the support plate 706, driving the rotating shaft 707 to rotate. At the same time, the transmission wheel 709 at the other end of the transmission rod 704 pulls the pressure rod 710 to move. When the transmission rod 704 moves towards the oil tank 701, the pressure rod 710 pushes the extrusion block 711 to slide in the oil tank 701. The sealing ring on the side of the extrusion block 711 ensures that the oil tank 701 is sealed, so that the lubricating oil is pressed into the limiting shell 608 through the oil supply pipe 702 to lubricate the contact part between the moving cam 603 and the limiting shell 608.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
