Description

Technical Field

[0001] This invention relates to the field of insulation board lifting and conveying technology, specifically to a steel wire mesh combined insulation board lifting and conveying device. Background Technology

[0002] In the insulation board production process, the lifting conveyor is a key piece of equipment connecting upstream and downstream processes on the production line. Its core function is to accurately transfer the insulation boards delivered by the conveyor belt to the carrying mechanism. With the help of a positioning mechanism and lifting drive components, the vertical transfer of the insulation boards is completed, ensuring continuous and efficient operation of the entire production line. Wire mesh composite insulation boards are a type of insulation board, formed by combining wire mesh and insulation core material. They come in two structural forms: double-sided wire mesh and single-sided wire mesh. The single-sided wire mesh composite insulation board has a flat surface on the side without the wire mesh, allowing it to be directly transported by rollers or belt conveyors.

[0003] Chinese patent application CN121020183A discloses a lifting and conveying device for an insulation board production line. The device includes a support base, with a lifting assembly for driving the insulation board up and down mounted on the top of the support base. A connecting seat is installed at the moving end of the lifting assembly. A dual-axis motor is installed inside the connecting seat. A swing rod is fixedly connected to the top output end of the dual-axis motor. Both ends of the swing rod are movably connected to hinge rods. A moving plate is hinged to one end of each hinge rod. Three connecting plates are fixedly connected to the top of the moving plate. A sliding rod is fixedly connected to the inner side of each connecting plate, and a moving block is slidably connected to the outer side of the sliding rod. Through the hinge rod transmission, the moving plate slides smoothly along the sliding groove of the connecting seat, causing two sets of clamping wheels to synchronously approach the insulation board. A spring on the outer side of the sliding rod can adaptively extend and retract according to the surface shape of the insulation board after the clamping wheels contact it.

[0004] The lifting and conveying device for insulation board production lines described in the aforementioned patent requires two robotic arms to pneumatically grip the insulation boards on the conveyor belt. After placing the boards on the lifting support plate, the board is locked in place by an elastic fixing mechanism before the lifting process can begin. Once the board is in place, the locking structure must be released, and then the board is pushed out at low speed by a pneumatic clamping device or a pushing mechanism. The entire process is cumbersome, the transfer cycle of a single board is long, the production and conveying efficiency is low, and it cannot transfer single-sided steel wire mesh combined insulation boards, making it difficult to meet actual production needs. In addition, when the surface of the support plate is smooth, it is not conducive to fixing, while when it is rough, there is a risk of causing the insulation board to shift when pushing or gripping it, resulting in grinding damage to the bottom of the board. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of low lifting and conveying efficiency and easy wear and damage to the bottom plate of the insulation board in general insulation board lifting and conveying devices. This invention provides a steel wire mesh combined insulation board lifting and conveying device.

[0007] Furthermore, the lifting assembly includes a lead screw rotatably connected between the upper and lower walls of the machine base cavity, an encoder sleeved on the lead screw mounted on the upper wall of the machine base cavity, the lead screw being driven by a motor mounted on the upper end of the machine base, a slider threaded onto the lead screw being slidably engaged in the machine base, a connecting plate being fixedly connected to the front end of the slider, and an L-shaped support arm being fixedly connected to the front end of the connecting plate.

[0008] Furthermore, the inner baffle is fixedly connected to the upper front side of the connecting plate.

[0009] Furthermore, both the upper and lower roller conveyors have a linear array of several rollers, and each pair of rollers in the upper and lower roller conveyors is connected by a transmission belt. The rollers in the lower roller conveyor that are located in the gaps correspond vertically to each of the auxiliary rollers. The rollers in the lower roller conveyor that are located in the gaps are arranged alternately with each of the L-shaped support arms. The inner wall of the lower roller conveyor has clearance grooves that correspond to the front ends of each L-shaped support arm.

[0010] Furthermore, the transmission assembly includes a linkage belt movably connected between the front ends of each pair of adjacent auxiliary rollers. A driven bevel gear is fixedly connected to the front end of the leftmost auxiliary roller. A double-headed bevel gear is rotatably connected to the front end of the L-shaped swing frame and meshes with the driven bevel gear. A driving bevel gear is fixedly connected to the front end of the rightmost rotating roller of the upper rotating roller conveyor. The double-headed bevel gear is rotatably connected to the right end of the upper rotating roller conveyor and meshes with the driving bevel gear. The rotating end of the L-shaped swing frame is coaxial with the double-headed bevel gear. A support arm rotatably connected to the L-shaped swing frame is provided on the right wall of the machine base.

[0011] Furthermore, the adjustment assembly includes a T-shaped guide rod that is slidably inserted into the rear wall of the slide groove in each L-shaped support arm. A longitudinal groove is provided between the left and right walls of the slide groove, and an inclined groove is provided between the left and right walls of the roller frame. The T-shaped guide rod is movably engaged with the inclined groove and the longitudinal groove respectively. A connecting strip is fixedly connected between the rear ends of each T-shaped guide rod. Two symmetrical abutment rods are fixedly connected to the rear ends of the connecting strips. An abutment spring is fixedly connected between the connecting strips and the lower wall of the connecting plate. Guide strips that movably abut against the abutment rods are installed on the left and right walls of the front end of the machine base. The top of the guide strip includes a wedge-shaped protrusion with an inclined surface, and the rear end of the abutment rod has a ball bearing.

[0012] Furthermore, the adjustment assembly also includes a spring pin that is slidably inserted into the connecting plate, and the connecting strip has a slot that is offset from the spring pin.

[0013] Furthermore, a support plate is installed on the lower front side of the base, and a top rod that abuts against the spring pin is fixedly connected to the upper end of the support plate. A rectangular groove adapted to the top rod and passing through the bayonet is opened on the connecting strip, and the width of the rectangular groove is smaller than the diameter of the bayonet.

[0014] Furthermore, a limiting plate is slidably engaged between the inner wall of the lower roller conveyor and the right wall of the notch. The bottom of the limiting plate is fixedly connected to an elastic serpentine plate that is elastically connected to the lower wall of the lower roller conveyor. The upper end of the elastic serpentine plate abuts against the lower wall of the rightmost L-shaped support arm.

[0015] The beneficial effects of this invention are as follows: 1. This invention completes the low-level feeding and high-level discharging of steel wire mesh composite insulation boards by setting up upper and lower roller conveyors respectively. With the help of the lifting component, the L-shaped support arm is driven to vertically insert to realize the lifting and unloading of the board. At the same time, the L-shaped swing frame driven by the cylinder adaptively and quickly deflects to complete the feeding avoidance and unloading receiving actions. The entire transfer process is smooth and coordinated, which greatly improves the conveying and transfer efficiency of steel wire mesh composite insulation boards. It can be adapted to both ordinary insulation board and single-sided steel wire mesh insulation board production lines, making the equipment more widely applicable and significantly improving its overall practicality.

[0016] 2. This invention uses multiple sets of linearly arranged L-shaped support arms to support the insulation board. During the lifting stage, the friction protrusions at the upper end of the support arms adhere to the bottom surface of the insulation board, utilizing the weight of the board to increase the friction on the contact surface. This allows for stable lifting and positioning without the need for additional clamping mechanisms, simplifying the structure and reducing board compression damage. When the board is lifted to the high-position discharge station, the adjustment component automatically drives the roller frame to lift the top roller, slightly lifting the board and detaching it from the friction protrusions. The discharge process is supported and transported solely by the rolling of the top roller, completely avoiding the problem of friction protrusions scraping and grinding the bottom surface of the insulation board. This effectively protects the appearance of the board and the core material structure, improving the finished product qualification rate. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] Example 1, as Figures 1-8As shown, a steel wire mesh composite insulation board lifting and conveying device includes a base 1 and an upper rotary roller conveyor 7 and a lower rotary roller conveyor 9 arranged above and below the front side of the base 1. A lifting assembly is provided in the base 1. An inner baffle 24 is provided on the upper side of the front end of the lifting assembly. The inner baffle 24 is fixedly connected to the upper front end of the connecting plate 23. A number of L-shaped support arms 3 in a linear array are fixedly connected to the front end of the lifting assembly. A number of friction protrusions 31 in two rows are provided on the upper end of the L-shaped support arms 3. A sliding groove is provided in the middle of the L-shaped support arm 3 and a roller frame 4 is slidably engaged in the sliding groove. A top roller 42 is rotatably connected to the top of the roller frame 4. An adjustment assembly that drives the roller frame 4 to move upward is movably arranged between the bottoms of the number of L-shaped support arms 3. The upper roller conveyor 7 has an open opening on its right side and is rotatably connected to an L-shaped swing frame 8. The right wall of the base 1 is provided with a support arm that is rotatably connected to the L-shaped swing frame 8. A cylinder 81 is movably connected between the L-shaped swing frame 8 and the right wall of the base 1. Several auxiliary rollers 82 in a linear array are rotatably connected to the inner side of the L-shaped swing frame 8. A transmission component is provided at the front end of the L-shaped swing frame 8. The lower roller conveyor 9 has a notch on the left side of its rear end. A pressure sensing plate 91 is provided on the left wall of the inner cavity of the lower roller conveyor 9.

[0021] Both the upper roller conveyor 7 and the lower roller conveyor 9 have several rollers arranged in a linear array. A transmission belt is provided between each pair of rollers in the upper roller conveyor 7 and the lower roller conveyor 9. The rollers in the lower roller conveyor 9 that are in the gap correspond vertically to each of the auxiliary rollers 82. The rollers in the lower roller conveyor 9 that are in the gap are arranged alternately with each of the L-shaped support arms 3. The inner wall of the lower roller conveyor 9 has a clearance groove that corresponds to the front end of each of the L-shaped support arms 3.

[0022] In use, both the upper roller conveyor 7 and the lower roller conveyor 9 are installed on the ground through corresponding support mechanisms. Both the upper roller conveyor 7 and the lower roller conveyor 9 are driven by an external drive mechanism to drive one of the rollers, thereby controlling the operation of all rollers by various transmission belts. The upper roller conveyor 7, together with the transmission assembly, drives each auxiliary roller 82, and together with the lower roller conveyor 9, conveys the wire mesh composite insulation board to the left. The conveyed wire mesh composite insulation board has a wire mesh on one side and the insulation board is at the bottom. In addition, the roller frame 4 drives the top roller 42 to be in a retracted state, and the upper end of the top roller 42 is lower than the upper end surface of the friction protrusion 31. During operation, the lifting assembly moves the L-shaped support arm 3 to the preset lowest position. Under the control of the external controller, the cylinder 81 automatically extends, causing the L-shaped swing frame 8 to deflect downwards into a vertical position. The upper surface of the friction protrusion 31 on the L-shaped support arm 3 is lower than the upper surface of the roller in the lower roller conveyor 9. When the lower roller conveyor 9 transports the wire mesh composite insulation board to the gap and the left end abuts against the pressure sensor plate 91, the pressure sensor plate 91 feeds back to the external controller to control the lifting assembly to move the L-shaped support arm 3 upwards. The L-shaped support arm 3 then utilizes friction... The protrusions 31 lift the wire mesh composite insulation board upwards until the lower end of the wire mesh composite insulation board just exceeds the upper end of the auxiliary roller 82, which was originally horizontal. During the lifting process, several friction protrusions 31 contact the rough surface of the lower end of the insulation board at the bottom of the wire mesh composite insulation board. The weight of the board increases the friction of the contact surface, and the board can be stably lifted and positioned without additional clamping mechanism, thus improving the transfer efficiency. In addition, the front end of the L-shaped support arm 3 and the inner baffle 24 limit the front and rear movements, further ensuring the stability of feeding and lifting. After being raised to the preset height, the adjusting component drives the roller frame 4 to move upward. The roller frame 4 drives the top roller 42 to slightly lift the wire mesh insulation board at multiple points, disengaging it from the friction protrusion 31. Subsequently, the external controller controls the cylinder 81 to drive the L-shaped swing frame 8 to quickly return to a horizontal position and controls the lifting component to move down to the lowest position. The corresponding wire mesh insulation board then automatically falls onto the auxiliary roller 82 and is driven to the left by the rotary conveyor 7. The top roller 42 moves automatically in coordination with the movement of the wire mesh insulation board, thereby preventing the friction protrusion 31 from continuously scraping and abrading the bottom core material of the insulation board and preventing the board from being damaged. Compared with the traditional equipment that relies on pneumatic clamping, telescopic push rods for low-speed material pushing, and fixed rollers for slow material discharge, this device can control the L-shaped support arm 3 to move down again to pick up the material after releasing the wire mesh insulation board onto the auxiliary roller 82, without waiting for unloading, greatly shortening the discharge cycle and significantly improving the overall conveying efficiency. When the lifting assembly moves down to the lowest position in preparation for a new round of lifting of the wire mesh insulation board, the external controller once again controls the cylinder 81 to extend, causing the L-shaped swing frame 8 to deflect downwards and move into a vertical position to avoid being lifted.

[0023] Example 2, based on the above examples, such as... Figure 2 and Figure 4 As shown, the lifting assembly includes a lead screw 2 rotatably connected between the upper and lower walls of the inner cavity of the base 1. An encoder 21 is installed on the upper wall of the inner cavity of the base 1 and sleeved on the lead screw 2. The lead screw 2 is driven by a motor installed on the upper end of the base 1. A slider 22 threadedly sleeved on the lead screw 2 is slidably engaged in the base 1. A connecting plate 23 is fixedly connected to the front end of the slider 22. An L-shaped support arm 3 is fixedly connected to the front end of the connecting plate 23.

[0024] During use, the external controller directly controls the motor to drive the lead screw 2 to rotate in both directions, causing the slider 22 to move the connecting plate 23 and the L-shaped support arm 3 up and down. When transporting large steel wire mesh composite insulation boards, the support area formed by the distribution of the L-shaped support arm 3 is relatively large. Therefore, compared with the general ring-driven rotary elevator, the vertical lifting and interlacing form can reduce the space occupied by the device and optimize the layout of the processing equipment. Furthermore, the encoder 21 monitors and provides feedback on the rotation information of the lead screw 2, which can accurately control the L-shaped support arm 3 to move the steel wire mesh composite insulation board up and down to the specified height.

[0025] Example 3, based on the above examples, such as Figure 1 and Figure 6 As shown, the transmission assembly includes a linkage belt movably connected between the front ends of each of the two adjacent auxiliary rollers 82. A driven bevel gear 83 is fixedly connected to the front end of the leftmost auxiliary roller 82. A double-headed bevel gear 72 that meshes with the driven bevel gear 83 is rotatably connected to the front end of the L-shaped swing frame 8. A driving bevel gear 71 is fixedly connected to the front end of the rightmost roller of the upper roller conveyor 7. The double-headed bevel gear 72 is rotatably connected to the right end of the upper roller conveyor 7 and meshes with the driving bevel gear 71. The rotating end of the L-shaped swing frame 8 is coaxial with the double-headed bevel gear 72.

[0026] This design ensures that before and after the L-shaped swing frame 8 deflects, each auxiliary roller 82 is always connected to the roller drive in the upper roller conveyor 7 and rotates in the same direction and synchronously. Each roller and the auxiliary roller 82 have the same size and specifications, so that after the L-shaped support arm 3 places the wire mesh composite insulation board on the auxiliary roller 82, each roller and the auxiliary roller 82 can smoothly convey the wire mesh composite insulation board to the left, reducing the probability of slippage and avoiding grinding of the insulation board part of the wire mesh composite insulation board.

[0027] Example 4: Based on the above examples, as follows... Figures 4-5 As shown, the adjustment assembly includes a T-shaped guide rod 43 that is slidably inserted into the rear wall of the slide groove in each L-shaped support arm 3. The rear end of the roller frame 4 has a movable opening corresponding to the T-shaped guide rod 43. A longitudinal groove 32 is provided between the left and right walls of the slide groove, and an inclined groove 41 is provided between the left and right walls of the roller frame 4. The T-shaped guide rod 43 is movably engaged with the inclined groove 41 and the longitudinal groove 32 respectively. A connecting strip 44 is fixedly connected between the rear ends of each T-shaped guide rod 43. Two symmetrical abutment rods 46 are fixedly connected to the rear ends of the connecting strip 44. An abutment spring 47 is fixedly connected between the connecting strip 44 and the lower wall of the connecting plate 23. Guide strips 5 are installed on the left and right walls of the front end of the machine base 1, which movably abut against the abutment rods 46. The top of the guide strip 5 includes a wedge-shaped protrusion with an inclined surface, and the rear end of the abutment rod 46 has a ball.

[0028] Initially, the abutment spring 47 is in a stretched state. When the slider 22 drives the connecting plate 23 to move the L-shaped support arm 3 to the highest position, the two abutment rods 46 just abut against the wedge-shaped protrusion at the top of the guide bar 5 and move forward under the drive of the inclined plane. The corresponding connecting bar 44 drives each T-shaped guide rod 43 to move forward along the longitudinal groove 32. The synchronous T-shaped guide rods 43 squeeze the inclined groove 41, drive the roller frame 4 to move the top roller 42 upward, and the top roller 42 slightly lifts the wire mesh combined insulation board so that it is separated from the friction protrusion 31. Thus, when the slider 22 drives the connecting plate 23 to move the L-shaped support arm 3 downward and the wire mesh combined insulation board is placed on the auxiliary roller 82 for output, it can avoid the friction protrusion 31 from grinding and scratching the insulation board at the bottom of the wire mesh combined insulation board, which would cause damage and result in defective products.

[0029] The adjustment assembly also includes a spring pin 25 that slides onto the connecting plate 23, and a slot 45 on the connecting strip 44 that is offset from the spring pin 25.

[0030] Initially, the elastic pin 25 is in a compressed state. When the L-shaped support arm 3 moves up to the highest position and the connecting strip 44 moves forward, the bayonet 45 is simultaneously driven forward and moves forward to the correct position, where it connects with the elastic pin 25. The elastic pin 25 automatically extends into the bayonet 45 to limit the connecting strip 44, preventing the subsequent slider 22 from driving the connecting plate 23 to cause the L-shaped support arm 3 to move down and release the wire mesh composite insulation board. This resets the top roller 42 that lifts the wire mesh composite insulation board.

[0031] Example 5, based on the above examples, such as... Figures 3-5 As shown, a support plate 6 is installed on the lower front side of the base 1. A push rod 61 that abuts against the spring pin 25 is fixedly connected to the upper end of the support plate 6. A rectangular groove is opened on the connecting strip 44 to fit the push rod 61 and pass through the bayonet 45. The width of the rectangular groove is smaller than the diameter of the bayonet 45. The rectangular groove allows the push rod 61 to move back and forth, but does not allow the spring pin 25 to move.

[0032] When the slider 22 moves the connecting plate 23 down to the lowest position, the top rod 61 is inserted into the rectangular groove and pushes the spring pin 25 in the bayonet 45 upward. Correspondingly, under the pulling force of the abutment spring 47 and the gravity of the roller frame 4, the connecting strip 44 moves backward to reset, and the roller frame 4 drives the top roller 42 to move down to reset, thereby ensuring that when the new steel wire mesh composite insulation board is lifted using the L-shaped support arm 3, the contact between the friction protrusion 31 and the bottom of the steel wire mesh composite insulation board is not affected.

[0033] Example 6, based on the above examples, such as Figures 7-8 As shown, a limiting plate 92 is slidably engaged between the inner wall of the lower roller conveyor 9 and the right wall of the notch. The bottom of the limiting plate 92 is fixedly connected to an elastic serpentine plate 93 that is elastically connected to the lower wall of the lower roller conveyor 9. The upper end of the elastic serpentine plate 93 abuts against the lower wall of the rightmost L-shaped support arm 3.

[0034] When the L-shaped support arm 3 moves upward to lift the steel wire mesh composite insulation board, the elastic serpentine plate 93 uses its own elasticity to drive the limiting plate 92 to move upward, blocking the steel wire mesh composite insulation board that is subsequently conveyed to the left by the lower roller conveyor 9; when the L-shaped support arm 3 moves downward to the lowest position, the rightmost L-shaped support arm 3 presses the elastic serpentine plate 93 downward, driving the limiting plate 92 to move downward. After the upper end of the limiting plate 92 is lower than the upper end of the roller, the steel wire mesh composite insulation board is automatically conveyed to the top of each L-shaped support arm 3.

[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
