Description

Technical Field

[0001] This invention relates to the technical field of keel assembly devices, specifically a light steel keel assembly device with an adjustable stop position. Background Technology

[0002] In the production process of light steel keel, in order to better meet customer needs, it is necessary to produce keels of fixed length. In actual production, the length of the keel needs to be changed frequently. After the keel is formed and cut, it enters the joining belt conveyor for joining after passing through the receiving belt. Because the length of the keel changes after the length is changed, while the support of the joining belt conveyor is fixed, this will cause the length of the keel exposed at both ends of the support to be inconsistent, which will eventually lead to the failure of joining. Therefore, it is necessary to adjust the stop position of the keel on the receiving belt.

[0003] Although the stop mechanism in the existing equipment can automatically adjust the position of the stop, the stop mechanism can only move unilaterally relative to the position of the assembly belt support. When assembling longer keel sections, the displacement of the stop mechanism relative to the assembly belt support will also increase. The increased displacement means that the length of the area used for the movement of the stop mechanism will also increase, thereby increasing the volume of the entire device and thus increasing the manufacturing cost of the entire device. Summary of the Invention

[0004] The purpose of this invention is to provide a light steel keel assembly device with an adjustable stop position, in order to solve the technical problem that the existing stop mechanism can only move unilaterally relative to the position of the assembly belt support. When assembling a long keel, the displacement of the stop mechanism relative to the assembly belt support will also increase. The increase in displacement means that the length of the area used for the movement of the stop mechanism will also increase, thereby increasing the volume of the entire device and thus increasing the manufacturing cost of the entire device.

[0005] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution:

[0007] The first frame is used for the installation of the conveyor belt, and grooves are provided on both sides of the first frame;

[0008] A sliding transmission assembly is installed at one end of the first frame, and the sliding end of the sliding transmission assembly extends into the two sliding grooves;

[0009] A stop assembly is installed in the sliding transmission assembly, and the stop assembly can slide along the slide groove under the driving action of the sliding transmission assembly;

[0010] The second frame is installed below the first frame to support the light steel keel that slides down from the first frame. The surface of the second frame has a limit groove along its length.

[0011] An adjustment component is installed in the limiting groove, and one end of the adjustment component extending out of the limiting groove is connected to the transmission end of the sliding transmission component through a transmission component.

[0012] The conveyor is provided in three parts. The middle conveyor is fixedly connected to the limiting groove, and the two conveyors on both sides are slidably connected to the adjusting assembly.

[0013] Under the action of external driving force, the sliding transmission assembly and the adjustment assembly cooperate to adjust the distance between the stop end of the stop assembly and one of the sliding conveying components.

[0014] As a preferred embodiment of the present invention, the sliding transmission assembly includes a first threaded screw, a slider, and a transmission gear;

[0015] The first threaded screw rotates in one of the said grooves;

[0016] There are two sliders, both of which are slidably connected in the groove and both of which are connected to the stop assembly. Under the drive of an external drive source, the first threaded screw drives the sliders and the stop assembly to slide synchronously.

[0017] A transmission gear is installed on one end of the first threaded screw that extends out of the side wall of the first frame. A main gear is connected to one end of the first threaded screw that passes through the transmission gear. The main gear is meshed with the adjustment assembly.

[0018] As a preferred embodiment of the present invention, two first threaded screws are provided, and the two first threaded screws are rotatably connected to the two slides respectively. A slider is threadedly connected to each of the two first threaded screws. A transmission gear is connected to the end of each of the two first threaded screws that extends out of the side wall of the first frame. A transmission chain is connected between the two transmission gears.

[0019] One of the first threaded screws is connected to a main gear at one end that passes through the transmission gear, and the main gear is meshed with the adjusting assembly.

[0020] As a preferred embodiment of the present invention, the stop assembly includes a support frame and a stop seat. The support frame spans across the first frame, and both ends of the support frame are respectively connected to two sliders. The stop seat is connected to the side of the support frame facing the keel.

[0021] As a preferred embodiment of the present invention, the adjusting assembly includes a second threaded screw, a sliding block, and a secondary gear;

[0022] The second threaded screw is rotatably connected in the limiting groove;

[0023] There are three sliding blocks, all of which are connected to the second threaded screw. The middle sliding block is fixed in the limiting groove, and the two sliding blocks on both sides are slidably connected in the limiting groove. The ends of the three sliding blocks away from the limiting groove are respectively connected to the three conveying components.

[0024] A secondary gear is connected to one end of the second threaded screw that extends out of the side wall of the second frame, and a toothed chain connects the secondary gear and the main gear.

[0025] As a preferred embodiment of the present invention, the second threaded screw includes two threaded sections with opposite threads and a smooth section. The two threaded sections are respectively connected to both sides of the smooth section. The smooth section is rotatably connected to the middle sliding block. The two threaded sections are respectively threadedly connected to the sliding blocks located on both sides.

[0026] As a preferred embodiment of the present invention, the thread direction of the threaded segment near one end of the auxiliary gear is opposite to the thread direction of the first threaded screw located on the same side of the threaded segment.

[0027] As a preferred embodiment of the present invention, a guide groove is provided on the side of the first frame close to the second frame along its own length direction, and several transition plates are slidably connected in the guide groove, with the ends of the several transition plates opposite to the guide groove being flush with the conveying surface of the conveying component.

[0028] In a preferred embodiment of the present invention, two transition plates are provided. The ends of both transition plates facing away from the guide groove are fixedly connected to two conveying members located on either side via connectors, so that the two transition plates can move synchronously with the two conveying members. The guide groove is located above the slide groove to reduce interference from the slide groove on the sliding of the transition plates.

[0029] Compared with the prior art, the present invention has the following advantages:

[0030] This invention uses the linkage between the sliding transmission component and the adjusting stop component to drive the stop component and the conveyor to move synchronously. The movement state between the two is maintained in the opposite direction or in the opposite direction, so that the stop mechanism and the original belt conveyor support can move relative to each other. This controls the length of the keel exposed by the conveyor when the stop is stopped. The distance between the stop component and the conveyor can be adjusted twice, that is, the distance adjusted by the stop component is half of the original single adjustment distance, thereby reducing the length of the first frame, thereby reducing the manufacturing cost of the device and the footprint of the device.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] like Figure 1 As shown, a light steel keel assembly device with adjustable stop position includes a first frame 1, a sliding transmission assembly 3, a stop assembly 4, a second frame 5, an adjustment assembly 7, and a conveyor 8.

[0045] The first frame 1 is used for the installation of the conveyor belt, and the first frame 1 has grooves 2 on both sides;

[0046] The sliding transmission assembly 3 is installed at one end of the first frame 1, and the sliding end of the sliding transmission assembly 3 extends into the two sliding grooves 2;

[0047] The stop assembly 4 is installed in the sliding transmission assembly 3. Under the driving action of the sliding transmission assembly 3, the stop assembly 4 can slide along the slide groove 2.

[0048] The second frame 5 is installed below the first frame 1 to support the light steel keel that slides down from the first frame 1. The surface of the second frame 5 is provided with a limit groove 6 along its own length.

[0049] Adjustment component 7 is installed in limit groove 6. One end of adjustment component 7 extending out of limit groove 6 is connected to the transmission end of sliding transmission component 3 through transmission component.

[0050] There are three conveying components 8. The middle conveying component 8 is fixedly connected to the limiting groove 6, and the two conveying components 8 on both sides are slidably connected to the adjusting component 7.

[0051] The distance between the stop assembly 4 and the conveyor 8 is the length of the keel extending from both ends when the keel is assembled. If the lengths of the two ends of the conveyor 8 are not the same, it will affect the subsequent keel assembly. This device mainly controls the length of the keel exposed by the conveyor 8 when the stop is made by adjusting the distance between the stop assembly 4 and the conveyor 8, so that the lengths of the two sides of the conveyor 8 are the same.

[0052] Since the main function of the stop assembly 4 is to control the stopping position of the keel on the conveyor belt, the keel after being stopped slides down onto the second frame 5 under the pushing action of the outer pusher. At this time, when the keel slides onto the second frame 5, the lengths of the two ends extending out of the second frame 5 must be consistent to facilitate subsequent assembly. That is, the distance between the stop end of the stop assembly 4 and the conveying end of the second frame 5 is the length of the keel extending out. When assembling keels of different sizes, the lengths of the different keels extending out of the conveying end of the second frame 5 will be different, which requires the movement of the stop assembly 4.

[0053] Specifically, such as Figure 2 and Figure 4 As shown, the sliding transmission assembly 3 includes a first threaded screw 31, a slider 32, and a transmission gear 33;

[0054] The first threaded screw 31 rotates in one of the slides 2;

[0055] There are two sliders 32, both of which are slidably connected in the groove 2. Both sliders 32 are connected to the stop assembly 4. Under the drive of the external drive source, the first threaded screw 31 drives the sliders 32 to slide synchronously with the stop assembly 4.

[0056] The transmission gear 33 is installed on one end of the first threaded screw 31 that extends out of the side wall of the first frame 1. The first threaded screw 31 passes through the transmission gear 33 and is connected to the main gear 34. The main gear 34 is meshed with the adjusting component 7.

[0057] The stop assembly 4 mainly converts the rotational motion tendency into the linear motion tendency through the linkage between the first threaded screw 31 and the slider 32, so that the stop assembly 4 slides along the side wall of the first bracket. The first threaded screw 31 is driven by an external drive source, which can be a forward and reverse reversible motor. The forward and reverse reversible motor needs to be fixed to the first frame 1 or the second frame 5 by a fixing component.

[0058] During adjustment, if the length of the processed keel increases compared to the previously processed keel, the stop assembly 4 needs to move backward a certain distance in the direction of the keel's movement under the forward rotation driven by the external drive source. That is, the first threaded screw 31 drives the slider 32 to move backward along the slide groove 2 so that the position of the keel stop moves forward, thereby ensuring that the extension lengths at both ends are the same. Conversely, if the length of the processed keel decreases compared to the previously processed keel, the stop assembly 4 needs to move forward a certain distance in the direction of the keel's movement under the forward rotation driven by the external drive source.

[0059] Specifically, such as Figure 2As shown, the stop assembly 4 includes a support frame 41 and a stop seat 42. The support frame 41 spans across the first frame 1, and both ends of the support frame 41 are connected to two sliders 32 respectively. The stop seat 42 is connected to the side of the support frame 41 that faces the keel.

[0060] Since the two ends of the support frame 41 in the stop assembly 4 are respectively connected to the two sides of the first frame 1, and both ends of the support frame 41 have a tendency to slide, and the keel moves in a straight line along the conveyor belt, when the keel is stopped, the end face of the keel also needs to be kept horizontal, that is, the end face of the stop seat 42 needs to be kept perpendicular to the conveyor belt.

[0061] Specifically, such as Figure 2 and Figure 4 As shown, there are two first threaded screws 31, which are rotatably connected to two slide grooves 2 respectively. Each of the two first threaded screws 31 is threaded with a slider 32. A transmission gear 33 is connected to one end of each of the two first threaded screws 31 that extends out of the side wall of the first frame 1. A transmission chain 35 is connected between the two transmission gears 33. The first threaded screws 31 in the two slide grooves 2 move synchronously to drive the two corresponding sliders 32 to move synchronously, thereby ensuring that the support frame 41 is always perpendicular to the conveyor belt.

[0062] If the length of the keel to be processed is long, the distance that the stop assembly 4 needs to retract will increase. The increased retraction distance will increase the length of the first frame 1, thereby increasing the overall size of the device and the manufacturing cost of the equipment. In order to process the longer keel on the shorter first frame 1, the mutual movement between the stop assembly 4 and the conveyor 8 must be taken into account.

[0063] Specifically, such as Figure 1 and Figure 4 As shown, a first threaded screw 31 passes through one end of a transmission gear 33 and is connected to a main gear 34, which meshes with the adjusting assembly 7.

[0064] Furthermore, such as Figure 5 As shown, the adjusting assembly 7 includes a second threaded screw 71, a sliding block 72, and a secondary gear 73;

[0065] The second threaded screw 71 is rotatably connected in the limiting groove 6;

[0066] There are three sliding blocks 72. All three sliding blocks 72 are connected to the second threaded screw 71. The middle sliding block 72 is fixed in the limiting groove 6. The two sliding blocks 72 on both sides are slidably connected in the limiting groove 6. The end of the three sliding blocks 72 away from the limiting groove 6 is connected to the three conveying components 8 respectively.

[0067] The auxiliary gear 73 is connected to one end of the second threaded screw 71 that extends out of the side wall of the second frame 5, and a toothed chain 74 connects the auxiliary gear 73 and the main gear 34.

[0068] In the sliding transmission assembly 3 that drives the stop assembly 4 to move, the main gear 34 is connected to the auxiliary gear 73 in the adjustment assembly 7 via a toothed chain 74. When the sliding transmission assembly 3 moves, the main gear 34 and the auxiliary gear 73 move synchronously. The auxiliary gear 73 drives the second threaded screw 71 to rotate. The second threaded screw 71 drives the two sliding blocks 72 to move closer or further away from each other to accommodate keel assemblies of different lengths.

[0069] Furthermore, such as Figure 5 As shown, the second threaded screw 71 includes two threaded sections 711 with opposite threads and a smooth section 712. The two threaded sections 711 are respectively connected to both sides of the smooth section 712. The smooth section 712 is rotatably connected to the middle sliding block 72. The two threaded sections 711 are respectively threadedly connected to the sliding blocks 72 located on both sides.

[0070] Furthermore, the thread direction of the threaded section 711 near the end of the auxiliary gear 73 is opposite to the thread direction of the first threaded screw 31 located on the same side of the threaded section 711.

[0071] Since the thread direction of the threaded section 711 near the end of the auxiliary gear 73 is opposite to the thread direction of the first threaded screw 31 located on the same side of the threaded section 711, that is, the movement trends of the stop assembly 4 and the conveying member 8 are opposite, that is, they move in the same direction or in opposite directions.

[0072] If the length of the processed keel increases compared to the previous processed keel, the stop assembly 4 needs to retreat a certain distance in the direction of the keel's movement under the forward rotation driven by the external drive source. That is, the first threaded screw 31 drives the slider 32 to retreat. At this time, since the first threaded screw 31 and the second threaded screw 71 can be connected by transmission and their threads are opposite, when the stop assembly 4 retreats, the conveyor 8 advances the same distance. The positions of both the stop assembly 4 and the conveyor 8 are adjusted, that is, the distance between the stop assembly 4 and the conveyor 8 is adjusted twice. That is, the distance adjusted by the stop assembly 4 is half of the original single adjustment distance, thereby reducing the length of the first frame 1.

[0073] After the stop assembly 4 is adjusted to the appropriate position, the keel located on the first frame 1 needs to slide down onto the second frame 5 under external pushing force. Since there is a drop between the first frame 1 and the second frame 5, a platform is set up for the keel to slide down onto the second frame 5 more accurately.

[0074] Specifically, such as Figure 1 , Figure 2 and Figure 4As shown, a guide groove 9 is provided on one side of the frame close to the second frame 5 along its own length. Several transition plates 10 are slidably connected in the guide groove 9. The ends of the several transition plates away from the guide groove 9 are flush with the conveying surface of the conveying component 8.

[0075] The transition plate 10 serves as a platform for the keel to slide down.

[0076] The guide groove 9 is located above the slide 2 to reduce the interference of the slide 2 on the sliding of the transition plate 10.

[0077] Since the conveyor 8 mainly serves to convey the keel, the area between the two conveyor 8 on both sides is the main keel support area during conveying. The position of the conveyor 8 is constantly changing. In order to ensure that the keel can slide stably onto the conveyor 8.

[0078] Specifically, such as Figure 1 and Figure 3 As shown, the number of transition plates 10 is set to two. The ends of the two transition plates 10 that are away from the guide groove 9 are fixedly connected to the two conveying components 8 located on both sides through connectors, so that the two transition plates 10 can move synchronously with the two conveying components 8.

[0079] Among them, the conveyor is a conventional conveying device mechanism, which mainly functions to convey objects.
