Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a parts conveying device. Background Art

[0002] In order to ensure that auto parts can be accurately transported according to the set route and speed, and reduce the problems of incorrect placement or loss that may be caused by manual handling, and ensure the accuracy and stability of the production process, conveyor belts are usually used to transport auto parts. However, some shaft parts are usually slender in shape, and are prone to rolling and tilting on the conveyor belt, making it difficult to maintain a stable posture. At the same time, the surface of the conveyor belt is relatively flat, and the support for shaft parts is not comprehensive enough, and it cannot adapt well to its shape characteristics, which easily causes the shaft parts to shake during transportation.

[0003] In order to avoid similar problems, a limiting structure is usually installed on the surface of the conveyor belt. For example, the authorization publication number CN220844081U discloses an automobile parts processing and conveying device, which mainly prevents the automobile spindle, spherical parts and small parts from falling through the setting of rotating rods, conveyor belts, baffles and placement grooves, thereby improving the transportation stability of automobile parts.

[0004] However, although the rolling of shaft parts can be avoided by setting up rotating rods, conveyor belts, baffles and placement grooves (hereinafter collectively referred to as limiting structures), these limiting structures densely distributed in the conveyor will affect the ability of the conveyor belt to convey large parts, resulting in a decrease in the ability of the conveyor belt to carry large parts. At the same time, when these limiting structures are rotated to the corner position of the conveyor belt, they will deform together with the conveyor belt, thereby causing the limiting structures to deform, and the durability of this equipment is reduced. Therefore, in order to improve the application scope and durability of the conveyor belt, technical personnel in this field have proposed a parts conveying device to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a parts conveying device. The parts conveying device of this design utilizes a double-layer conveyor belt in conjunction with a placer and an interceptor embedded inside the double-layer conveyor belt, which can block shaft parts and avoid the problem that shaft parts cannot be conveyed due to rolling on the conveyor belt, and will not affect the conveyor belt's ability to carry large parts.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A parts conveying device comprises a conveyor belt mounting frame and a double-layer conveyor belt, wherein the double-layer conveyor belt is mounted in the conveyor belt mounting frame, and a plurality of placers and interceptors are mounted on the outer side wall of the inner layer conveyor belt of the double-layer conveyor belt, wherein the number of the placers and the number of interceptors are equal and adjacent placers and interceptors form a group, and an elastic rope is connected between the placers and interceptors in a group;

[0008] The placing device comprises a top mounting frame, a bottom rod, a placing end connecting ring and a compression spring, wherein the compression spring is fixed to the bottom of the top mounting frame, and the bottom rod is fixed to the bottom of the compression spring;

[0009] The interceptor comprises an interception frame, a driving wedge block, a sliding wedge block, a return spring, a driving right-angle plate, a driving toothed plate, a driving gear, a transmission toothed plate and an interception plate. The driving wedge block is limited and slidably connected to the front side of the interception frame. The return spring is in a stretched state and is installed in the inner cavity of the interception frame and is sleeved on the outer side of the driving wedge block. The sliding wedge block is limited and slidably connected to the lower side wall of the driving wedge block. The driving right-angle plate is fixed to the lower side wall of the sliding wedge block and the driving right-angle plate is limited and slidably connected to the front side wall of the interception frame. The lower side wall of the driving right-angle plate is fixedly connected with a pulling-in spring. The driving toothed plate is fixed to the rear end of the driving right-angle plate. The driving gear is installed in the inner cavity of the interception frame and meshes with the driving toothed plate. The transmission toothed plate is limited and slidably connected to the rear side wall of the interception frame and meshes with the driving gear. The interception plate is fixed on the top of the transmission toothed plate.

[0010] Through the above technical scheme, the conveying equipment conveys automobile parts through a double-layer conveyor belt. When shaft parts roll backward on the conveyor belt, the shaft parts will be pressed on the top mounting frame, thereby driving the compression spring to be compressed. At this time, the compression spring drives the elastic rope to pull the driving wedge block to slide forward. The driving wedge block sliding forward drives the sliding wedge block to slide down and then drives the driving right-angle plate to slide down. When the driving right-angle plate slides down, the driving tooth plate moving downward drives the driving gear to rotate and then drives the transmission tooth plate to move upward, so that the intercepting plate is lifted from the intercepting frame to block the shaft parts, thereby avoiding the problem that the shaft parts cannot be conveyed due to rolling on the conveyor belt.

[0011] Further, a placing end connecting ring is installed on the rear side wall of the top mounting frame, an intercepting end connecting ring is installed on the front side wall of the driving wedge block, and the elastic rope is connected between the driving wedge block and the intercepting end connecting ring;

[0012] Through the above technical solution, the installation of the elastic rope is facilitated by the intercepting end connecting ring and the placing end connecting ring.

[0013] Further, the elastic rope is in a taut state;

[0014] Through the above technical solution, when the top mounting frame slides downward, it will pull the driving wedge block to move forward.

[0015] Furthermore, a driving shaft is connected to the interior of the intercepting frame and is located directly behind the driving wedge block in a limited sliding manner. At the same time, the driving shaft is installed in the rear inner cavity of the intercepting frame through a spring. A lifting wedge block is fixedly connected to the rear side of the driving shaft. A matching wedge block is connected to the interior of the intercepting frame in a limited sliding manner. The bottom of the matching wedge block is tightly fitted with the upper wedge surface of the lifting wedge block.

[0016] Through the above technical solution, when the placer moves as a whole to the rotation position of the conveyor belt, the straight-line distance between the placer and the interceptor is shortened. At this time, the elastic rope no longer pulls the driving wedge block. At the same time, the return spring in the stretched state pulls the driving wedge block to move backward, and then squeezes the driving shaft to move backward. The driving shaft moving backward drives the lifting wedge block to move backward, and then drives the matching wedge block to be lifted.

[0017] Furthermore, a spring telescopic rod is fixedly connected to the top of the front side wall of the mating wedge block, and the other end of the spring telescopic rod is connected to a top inclined plate, and the top inclined plate is limitedly slidably connected to the top inclined groove of the interception frame;

[0018] Through the above technical solution, when the wedge block is lifted, the spring telescopic rod drives the push-up inclined plate to be lifted, and at the same time, the push-up inclined plate is pushed out along the top inclined groove of the intercepting frame, thereby ejecting the shaft parts from the conveyor belt to the processing device, avoiding the shaft parts from rolling at the end of the conveyor belt and being unable to be connected to the next processing unit.

[0019] Furthermore, a connecting rod is fixedly connected to the bottom of the interception frame, and the interceptor and the placement device are fixed to the outer side wall of the inner conveyor belt of the double-layer conveyor belt through the connecting rod and the bottom rod respectively;

[0020] Through the above technical scheme, the contact area between the placer and the interceptor and the inner conveyor belt of the double-layer conveyor belt can be reduced by connecting the rod and the bottom rod, preventing the conveyor belt from deforming due to deformation when it rotates to the corner position, thereby improving the overall durability of the device.

[0021] The utility model has the following beneficial effects:

[0022] 1. In the utility model, a double-layer conveyor belt is used in combination with a placer and an interceptor embedded inside the double-layer conveyor belt, which can block shaft parts and avoid the problem that shaft parts cannot be conveyed due to rolling on the conveyor belt, and will not affect the conveyor belt's ability to carry large parts.

[0023] 2. In the utility model, when the placer moves as a whole to the rotation position of the conveyor belt, the straight-line distance between the placer and the interceptor is shortened, and the reset spring pulls the driving wedge block to move backward, thereby pushing the shaft parts out of the conveyor belt and sending them to the processing device, avoiding the shaft parts from rolling at the end of the conveyor belt and being unable to be connected to the next processing unit.

[0024] 3. In the utility model, the contact surface between the placer and the interceptor and the inner conveyor belt of the double-layer conveyor belt can be reduced by connecting the rod and the bottom rod, so as to prevent the placer and the interceptor from deforming due to deformation when the conveyor belt rotates to the corner position, thereby improving the overall durability of the device.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Reference Figure 1-Figure 5 The utility model provides an embodiment: a parts conveying device, including a conveyor belt mounting frame 1 and a double-layer conveyor belt 2, the double-layer conveyor belt 2 is installed in the conveyor belt mounting frame 1, and the outer side wall of the inner conveyor belt of the double-layer conveyor belt 2 is installed with a plurality of placers 3 and interceptors 4, the number of the plurality of placers 3 and the plurality of interceptors 4 is equal and the adjacent placers 3 and interceptors 4 are a group, and an elastic rope 5 is connected between a group of placers 3 and interceptors 4, the placer 3 includes a top mounting frame 31, a bottom rod 32, a placing end connecting ring 34 and a compression spring 33, the compression spring 33 is fixed at the bottom of the top mounting frame 31, and the bottom rod 32 is fixed at the bottom of the compression spring 33.

[0036] The interceptor 4 includes an interception frame 41, a driving wedge block 48, a sliding wedge block 413, a return spring 49, a driving right-angle plate 46, a driving toothed plate 43, a driving gear 42, a transmission toothed plate 415 and an interception plate 416. The driving wedge block 48 is limitedly slidably connected to the front side of the interception frame 41, the return spring 49 is in a stretched state and is installed in the inner cavity of the interception frame 41 and sleeved on the outer side of the driving wedge block 48, the sliding wedge block 413 is limitedly slidably connected to the lower side wall of the driving wedge block 48, and the driving right-angle plate 4 6 is fixed on the lower side wall of the sliding wedge block 413 and drives the right-angle plate 46 to be limited and slidably connected in the front side wall of the interception frame 41. The lower side wall of the driving right-angle plate 46 is fixedly connected with a pulling spring 45. The driving tooth plate 43 is fixed to the rear end of the driving right-angle plate 46. The driving gear 42 is installed in the inner cavity of the interception frame 41 and meshes with the driving tooth plate 43. The transmission tooth plate 415 is limited and slidably connected to the rear side wall of the interception frame 41 and meshes with the driving gear 42. The interception plate 416 is fixed to the top of the transmission tooth plate 415.

[0037] The conveying equipment conveys automobile parts through a double-layer conveyor belt. When shaft parts roll backward on the conveyor belt, the shaft parts will be pressed on the top mounting frame 31, thereby driving the compression spring 33 to be compressed. At this time, the compression spring 33 drives the elastic rope 5 to pull the driving wedge block 48 to slide forward. The driving wedge block 48 sliding forward drives the sliding wedge block 413 to slide down, and then drives the driving right-angle plate 46 to slide down. When the driving right-angle plate 46 slides down, the driving tooth plate 43 moving to the downward side drives the driving gear 42 to rotate, and then drives the transmission tooth plate 415 to move upward, so that the intercepting plate 416 is lifted from the intercepting frame 41 to block the shaft parts, thereby avoiding the problem that the shaft parts cannot be conveyed due to rolling on the conveyor belt.

[0038] A placement end connecting ring 34 is installed on the rear side wall of the top mounting frame 31, and an interception end connecting ring 47 is installed on the front side wall of the driving wedge block 48. The elastic rope 5 is connected between the driving wedge block 48 and the interception end connecting ring 47. The installation of the elastic rope 5 is facilitated by the interception end connecting ring 47 and the placement end connecting ring 34. The elastic rope 5 is in a taut state. When the top mounting frame 31 slides downward, it will pull the driving wedge block 48 to move forward. The interior of the intercepting frame 41 and the rear of the driving wedge block 48 are limitedly slidably connected with a driving shaft 410. At the same time, the driving shaft 410 is installed in the rear inner cavity of the intercepting frame 41 through a spring. The rear side of the driving shaft 410 is fixedly connected with a lifting wedge block 411, and the interior of the intercepting frame 41 is limitedly slidably connected with a matching wedge block 412. The bottom of the matching wedge block 412 fits tightly with the upper wedge surface of the lifting wedge block 411. When the placer 3 moves as a whole to the rotation position of the conveyor belt, the straight-line distance between the placer 3 and the interceptor 4 is shortened. At this time, the elastic rope 5 no longer pulls the driving wedge block 48. At the same time, the return spring 49 in the tension state pulls the driving wedge block 48 to move backward, thereby squeezing the driving shaft 410 to move backward. The driving shaft 410 moving backward drives the lifting wedge block 411 to move backward, thereby driving the matching wedge block 412 to lift. A spring telescopic rod 414 is fixedly connected to the top of the front side wall of the matching wedge block 412. The other end of the spring telescopic rod 414 is connected to a top movable inclined plate 417. The top movable inclined plate 417 is limitedly slidably connected to the top inclined groove of the interception frame 41. When the wedge block 412 is lifted, the spring telescopic rod 414 drives the push-up inclined plate 417 to be lifted, and at the same time, the push-up inclined plate 417 is pushed out along the top inclined groove of the intercepting frame 41, thereby pushing the shaft parts out of the conveyor belt and sending them to the processing device, avoiding the shaft parts from rolling at the end of the conveyor belt and being unable to be connected to the next processing unit.

[0039] A connecting rod 44 is fixedly connected to the bottom of the intercepting frame 41, and the interceptor 4 and the placer 3 are fixed to the outer wall of the inner conveyor belt of the double-layer conveyor belt 2 through the connecting rod 44 and the bottom rod 32 respectively. The contact area between the placer 3 and the interceptor 4 and the inner conveyor belt of the double-layer conveyor belt 2 can be reduced by the connecting rod 44 and the bottom rod 32, preventing the conveyor belt from deforming due to deformation when it rotates to the corner position, thereby improving the overall durability of the device.

[0040] Working principle: The conveying equipment conveys automobile parts through a double-layer conveyor belt. When shaft parts roll backward on the conveyor belt, the shaft parts will be pressed on the top mounting frame 31, thereby driving the compression spring 33 to be compressed. At this time, the compression spring 33 drives the elastic rope 5 to pull the driving wedge block 48 to slide forward. The driving wedge block 48 sliding forward drives the sliding wedge block 413 to slide down, thereby driving the driving right-angle plate 46 to slide down. When the driving right-angle plate 46 slides down, the driving tooth plate 43 moving downward drives the driving gear 42 to rotate, thereby driving the transmission tooth plate 415 to move upward, so that the intercepting plate 416 is lifted from the intercepting frame 41 to block the shaft parts, thereby avoiding the problem that the shaft parts cannot be conveyed due to rolling on the conveyor belt. When the placer 3 When the whole moves to the rotating position of the conveyor belt, the straight-line distance between the placer 3 and the interceptor 4 is shortened. At this time, the elastic rope 5 no longer pulls the driving wedge block 48. At the same time, the return spring 49 in the stretched state pulls the driving wedge block 48 to move backward, thereby squeezing the driving shaft 410 to move backward. The driving shaft 410 moving backward drives the lifting wedge block 411 to move backward, thereby driving the matching wedge block 412 to be lifted. When the matching wedge block 412 is lifted, the spring telescopic rod 414 drives the lifting inclined plate 417 to be lifted, and at the same time, the lifting inclined plate 417 is ejected along the top inclined groove of the interception frame 41, thereby ejecting the shaft parts out of the conveyor belt and sending them to the processing device, thereby avoiding the shaft parts from rolling at the end of the conveyor belt and being unable to be connected to the next processing unit.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
