A material-proof conveying device for a hinge assembly machine

Abstract

This utility model provides an anti-jamming conveying device for a hinge assembly machine, belonging to the technical field of conveying devices. It includes a support base and a fixed frame mounted on the support base, with a first motor installed on one side of the support base. In this utility model, when the edges of the conveyor belts on both sides of the conveyor belt get caught on the conveyor belts during hinge conveying, friction ensures the fixation between the conveyor belts and the hinges. The conveyor belts, conveyor belts, and hinges maintain the same speed and continue to move, thus ensuring the continued conveying of the hinges. This effectively solves the problem of material jamming caused by burrs on the hinge sidewalls catching on the sidewalls of the conveying channel, preventing subsequent hinge workpieces from accumulating and causing blockages. Simultaneously, the positioning blocks can adjust the width of the conveying mechanism according to the length of the hinge, ensuring a stable gap between the hinge and the conveying structure, eliminating swaying space, and further preventing material jamming.

Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and more specifically, to an anti-jamming conveying device for a hinge assembly machine. Background Technology

[0002] A hinge assembly machine is a specialized piece of equipment used for the automated production of hinges, such as door hinges, cabinet hinges, and industrial hinges. It is used to precisely assemble the various components of a hinge (such as hinge blades, pins, bearings, screws, etc.) according to process requirements and to complete subsequent processes such as inspection and sorting.

[0003] In existing technologies, stable material conveying is crucial for the normal operation of the assembly machine during the automated assembly process of hinges. However, existing hinge assembly machine conveying devices are prone to jamming when the produced hinges have slight dimensional deviations and burrs on their edges. This can cause the hinge edges to snag against the channel edge, halting the conveying process. Consequently, subsequently conveyed hinges may accumulate at this point, leading to material jamming. Therefore, inventing an anti-jamming conveying device for hinge assembly machines to solve these problems has become a pressing issue for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an anti-jamming conveying device for a hinge assembly machine, which aims to solve the problem that in the existing hinge assembly machine conveying device, the edge of the hinge is easily caught with the edge of the channel during material conveying, causing the conveying to stop. At this time, the hinges conveyed later are prone to accumulate at this position, resulting in material jamming.

[0005] This utility model is implemented as follows:

[0006] This utility model provides an anti-jamming conveying device for a hinge assembly machine, including a support base and a fixed frame disposed on the support base. A first motor is installed on one side of the support base, and two symmetrical conveying wheels are installed between the two support bases. A conveyor belt is installed on the outer wall of the conveying wheels.

[0007] One side of each of the two fixed frames is equipped with a connecting rod that is fixedly connected to the side wall of the support base. A second motor is installed at the upper end of one of the fixed frames. A pulley is installed on the inner wall of the fixed frame, and a transmission belt is installed on the outer wall of the two pulleys.

[0008] Preferably, the two end sidewalls of the conveyor wheel are rotatably connected to the inner wall of the support base, the conveyor wheel and the conveyor belt are connected by transmission, the output end of the first motor is fixedly connected to one end of one of the conveyor wheels, and the bottom end of the support base is fixedly connected to a support leg.

[0009] The two end sidewalls of the pulley are rotatably connected to the inner wall of the fixed frame, the output end of the second motor is fixedly connected to one end of the pulley, the two pulleys are connected to the transmission belt, and the outer sidewall of the transmission belt is provided with several grooves.

[0010] Preferably, the transmission belt is an elastic belt, and the upper side wall of the support base is provided with a plurality of equidistant limiting grooves, wherein the inner wall of the middle limiting groove is rotatably connected to a screw, and one end of the screw is fixedly connected to a knob.

[0011] Preferably, a positioning block is installed above the support base, and a plurality of limiting blocks that are slidably connected to the lower end of the positioning block are fixedly connected to the inner wall of the limiting groove.

[0012] Preferably, the inner wall of one of the limiting blocks is threadedly connected to the outer wall of the screw, and a plurality of mounting grooves are provided on one side of the outer wall of the positioning block. A rotatably connected extrusion roller is installed on the inner wall of the mounting groove, and the side wall of the extrusion roller is in contact with one side of the transmission belt.

[0013] The beneficial effects of this utility model are:

[0014] The drive belts installed on both sides of the conveyor belt ensure that when the edges of the drive belts get caught on the hinges during the conveying process, friction keeps the drive belts and hinges fixed. The drive belts, conveyor belts, and hinges all maintain the same speed and continue to move, thus ensuring the continued conveying of the hinges. This effectively solves the problem of material jamming caused by burrs on the hinge sidewalls getting caught on the sidewalls of the conveying channel, thereby preventing subsequent hinge workpieces from accumulating and causing blockages. At the same time, the positioning blocks can adjust the width of the conveying mechanism according to the length of the hinges, ensuring that the gap between the hinges and the conveying structure remains stable, eliminating swaying space, and further preventing the hinges from jamming.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example, refer to Figures 1-6 A hinge assembly machine anti-jamming conveying device includes a support base 1 and a fixed frame 3 set on the support base 1. A first motor 11 is installed on one side of the support base 1. Two symmetrical conveying wheels 2 are installed between the two support bases 1. A conveyor belt 21 is installed on the outer wall of the conveying wheels 2.

[0025] One side of each of the two fixed frames 3 is equipped with a connecting rod 31 that is fixedly connected to the side wall of the support base 1. A second motor 32 is installed at the upper end of one of the fixed frames 3. A pulley 33 is installed on the inner wall of the fixed frame 3, and a transmission belt 34 is installed on the outer wall of the two pulleys 33.

[0026] Furthermore, the two end sidewalls of the conveyor wheel 2 are rotatably connected to the inner wall of the support base 1, the conveyor wheel 2 and the conveyor belt 21 are connected by transmission, the output end of the first motor 11 is fixedly connected to one end of one of the conveyor wheels 2, the bottom end of the support base 1 is fixedly connected to the support leg 14, the two end sidewalls of the pulley 33 are rotatably connected to the inner wall of the fixed frame 3, the output end of the second motor 32 is fixedly connected to one end of the pulley 33, the two pulleys 33 and the transmission belt 34 are connected by transmission, and the outer sidewall of the transmission belt 34 is provided with several grooves 35.

[0027] It should be noted that: when the first motor 11 is started, it drives the conveyor wheel 2 to drive the conveyor belt 21, which transports the hinge through the conveyor belt 21. During the transport process, the second motor 32 is started simultaneously to drive the pulley 33 to drive the transmission belt 34, and the transmission speed of the transmission belt 34 and the conveyor belt 21 is kept consistent. During the transport process, when the burrs on the side wall of the hinge come into contact with the outer side wall of the transmission belt 34 and cause them to get caught, the friction force ensures that the transmission belt 34 and the hinge are fixed. At the same time, since the speed of the transmission belt 34 and the conveyor belt 21 is consistent, the transmission belt 34, the conveyor belt 21 and the hinge continue to move at the same speed, thereby ensuring the continued transport of the hinge. The setting of the transmission belt 34 effectively solves the problem of material jamming caused by the burrs on the side wall of the hinge getting caught with the side wall of the conveying channel, thereby avoiding the subsequent accumulation of hinge workpieces and blockage.

[0028] Meanwhile, the side wall of the transmission belt 34 near the hinge has several grooves 35, which allow the burrs on the edge of the hinge to be further inserted into the grooves 35, thereby further ensuring the relative fixation between the hinge and the transmission belt 34. This ensures that the transmission belt 34 and the conveyor belt 21 can carry the hinge for transport while driving at the same speed, further improving the smoothness of the hinge transport.

[0029] Furthermore, the transmission belt 34 is an elastic belt, and the upper side wall of the support base 1 is provided with multiple equidistant limiting grooves 12. The inner wall of the middle limiting groove 12 is rotatably connected to a screw 13, and one end of the screw 13 is fixedly connected to a knob 131. A positioning block 4 is installed above the support base 1, and the lower end of the positioning block 4 is fixedly connected to multiple limiting blocks 41 that are slidably connected to the inner wall of the limiting groove 12. The inner wall of one limiting block 41 is threadedly connected to the outer wall of the screw 13. Multiple mounting grooves 42 are provided on one side of the outer wall of the positioning block 4. A rotatably connected extrusion roller 43 is installed on the inner wall of the mounting groove 42, and the side wall of the extrusion roller 43 is in contact with one side of the transmission belt 34.

[0030] It should be noted that when conveying hinges of different lengths, the screw 13 is rotated by the knob 131, which drives the limiting block 41 on the outside of the screw 13 to move the positioning block 4 above. This causes the sidewalls of the multiple extrusion rollers 43 on one side of the positioning block 4 to press tightly against the sidewall of the transmission belt 34. During the transmission of the transmission belt 34, the sidewalls of the extrusion rollers 43 slide, causing the transmission belt 34 to deform under the action of elasticity. This changes the distance between the two sides of the transmission belt 34, thereby adjusting the width of the conveying mechanism. This prevents the hinges from swaying laterally in the channel if the width is too large, which could cause multiple hinges to hook or stack and jam. At the same time, it prevents the hinge edges from being rigidly blocked by the sidewalls if the width is too small, which would prevent them from passing through. The positioning block 4 can adjust the width of the conveying mechanism according to the length of the hinge, ensuring that the gap between the hinge and the conveying structure remains stable, eliminating swaying space, and further preventing the hinge from jamming.

[0031] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
