Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary conveying devices, in particular to an auxiliary adjustment mechanism applicable to multiple force application angles. Background Art

[0002] Generally, conveying devices used as slides, guardrails, guides, etc. are generally fixed on a support frame and cannot achieve real-time angle adjustment. When transporting materials with high transmission quality requirements or materials that are easily deformed on the surface, if the materials are placed improperly and cannot make full contact with the conveying device, it is extremely easy to cause material deformation.

[0003] Taking the example of using a fluent bar to assist in conveying a condenser, the condenser is placed on a plate chain line, and its side contacts the fluent bar roller. The plate chain line is used for transportation and the fluent bar is used for assistance to achieve stable conveying. However, due to a certain arc at the corner of the condenser, if the condenser is placed improperly, there will be a certain angle between the contact of the condenser and the fluent bar roller, resulting in too small contact area between the condenser and the fluent bar roller, even reaching point contact, causing film inversion and scratches. Moreover, when the condenser is double-layer or other condensers with larger weight, after the condenser runs on the plate chain for a certain distance, it is more likely to occur surface wear. Summary of the Invention

[0004] In order to overcome the disadvantages in the prior art that it is difficult for the conveying device to achieve real-time angle adjustment, the contact area between the material and the conveying device such as the fluent bar roller is small during the transmission process, which easily causes damage to the surface of the material, and the contact buffer between the material and the fluent bar roller is small, etc., the purpose of the present invention is to provide an auxiliary adjustment mechanism applicable to multiple force application angles.

[0005] The technical solution adopted by the present invention to solve its technical problems is: an auxiliary adjustment mechanism applicable to multiple force application angles, including a buckle, a spring, a connecting plate, a support screw, and an adjustment nut. The connecting plate is fixedly arranged. The buckle is snap-fitted and installed on the rear side of the conveying device. There is a groove on the conveying device, and the buckle is snap-fitted with the groove. The upper part of the connecting plate is hinged to the upper part of the buckle. One end of the support screw is fixed on the rear side of the buckle, and the other end of the support screw passes through the connecting plate. The spring is sleeved on the support screw, and the adjustment nut is arranged on the other end of the support screw.

[0006] As a further improvement of the present invention: the buckle is in the shape of a "U".

[0007] As a further improvement of the present invention: the upper part of the buckle is provided with a first hinge piece and the lower part is provided with a limiting piece.

[0008] As a further improvement of the present invention: the upper part of the connecting plate is provided with a second hinge piece, and the first hinge piece and the second hinge piece are rotationally connected through a hinge shaft.

[0009] As a further improvement of the present invention: the front end of the first hinge piece is concave downward to form a first limiting portion, and the front end of the limiting piece is bent upward to form a second limiting portion.

[0010] As a further improvement of the present invention: the first limiting portion and the second limiting portion are both engaged in the groove.

[0011] As a further improvement of the present invention: a buffer washer is provided between the spring and the support screw.

[0012] As a further improvement of the present invention: a buffer washer is provided between the buckle and the spring.

[0013] As a further improvement of the present invention: the support screw is provided with threads.

[0014] As a further improvement of the present invention: the conveying device is a flow strip or an apron plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Through simple mechanisms such as springs and hinges, the conveying device can adapt to incoming materials at different angles, maximizing the contact area between the material and the conveying device and reducing damage to the material surface caused by uneven force.

[0027] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] In order to solve the technical problems in the prior art such as the difficulty in achieving real-time angle adjustment of the conveying device, the small contact area between the material and the conveying device during the transmission process, which easily leads to damage to the material surface, and the small contact buffer between the material and the conveying device, the present invention is further described in conjunction with the accompanying drawings and embodiments:

[0029] Example 1:

[0030] like Figure 1 As shown, this embodiment discloses an auxiliary adjustment mechanism that can be applied to multiple force angles. The auxiliary adjustment mechanism is installed on the rear side of the conveying device 1, and includes a connecting plate 2, a buckle 3, a support screw 4, a spring 5 and a distance adjustment nut 6. The connecting plate 2 is fixedly arranged, and the rear side of the conveying device 1 is provided with a groove 101 that is engaged with the buckle 3. The upper part of the connecting plate 2 is hingedly connected to the upper part of the buckle 3. One end of the support screw 4 is fixed on the rear side of the buckle 3, and the other end of the support screw 4 is passed through the connecting plate 2, the connecting plate 2 is correspondingly provided with a mounting hole for accommodating the support screw 4, the spring 5 is sleeved in the support screw 4, and the adjustable nut 6 is provided on the other end of the support screw 4. The adjustable nut 6 is used to assist in adjusting and fixing the angle of the adjustment mechanism. When the front side of the conveying device 1 receives pressure, the buckle 3 and the conveying device 1 are squeezed toward the side of the connecting plate 2, and the spring 5 reacts to the conveying device 1. The angle is adjusted, the contact buffer is increased, and the contact area with the material is increased through the spring 5.

[0031] Specifically, a buffer washer 7 is provided between the adjusting nut 6 and the spring 5 to prevent loosening and protect components.

[0032] Preferably, the support screw 4 is provided with threads.

[0033] Preferably, a first hinge piece 301 is provided on the upper portion of the buckle 3, and a second hinge piece 201 is provided on the upper portion of the connecting plate 2. The first hinge piece 301 and the second hinge piece 201 are rotatably connected via a hinge shaft.

[0034] The auxiliary adjustment mechanism of this embodiment adopts basic parts such as spring 5. The elasticity of spring 5 can be replaced to adapt to different limits. The maximum angle of the adjustment mechanism can also be limited by rotating the distance adjustment nut 6. It can adapt to materials of different sizes, models, and weights, and can adapt to the angle between the material and the conveying mechanism, increase the contact area between the material and the conveying device 1, improve the fault tolerance rate during the material placement process, and reduce or eliminate the wear and tear of the product surface and the generation of indentations during the conveying process of the material by the conveying device 1; in addition, the mechanism is simple and easy to install, and the cost is low.

[0035] Example 2:

[0036] like Figure 1-Figure 5 As shown, this embodiment discloses an auxiliary adjustment mechanism that can be applied to multiple force angles. The auxiliary adjustment mechanism is installed on the rear side of the conveying device 1. The conveying device 1 is a smooth strip. The smooth strip includes a bracket and a roller 13. The bracket is provided with an upper bracket 11 and a lower bracket 12. The roller 13 is installed between the upper bracket 11 and the lower bracket 12. One end of the upper bracket 11 and the lower bracket 12 is provided with a groove 101.

[0037] The auxiliary adjustment mechanism includes a connecting plate 2, a buckle 3, a support screw 4, a spring 5 and a pitch-adjusting nut 6. The connecting plate 2 is fixedly arranged, such as fixing the connecting plate 2 on an object such as a support frame, for fixing the auxiliary adjustment mechanism as a whole. The upper part of the connecting plate 2 is hingedly connected to the upper part of the buckle 3, and the buckle 3 is fixed in the groove 101 to connect and fix the bracket. One end of the support screw 4 is fixed on the rear side of the buckle 3 to support the bracket. The other end of the support screw 4 is passed through the connecting plate 2, and the connecting plate 2 is correspondingly provided with a mounting hole to accommodate the support screw 4. The spring 5 is sleeved in the support screw 4, and the pitch-adjusting nut 6 is arranged on the other end of the support screw 4. The pitch-adjusting nut 6 is used to adjust and fix the angle of the auxiliary adjustment mechanism, and the spring 5 is used to buffer pressure and adjust the mechanical movement of the smooth strip.

[0038] Preferably, a hinge connection structure is provided between the upper part of the connecting plate 2 and the upper part of the buckle 3 for the movable connection of the connecting plate 2 and the buckle 3.

[0039] Preferably, the buckle 3 is in a "C" shape. A first hinge piece 301 is provided at the upper part of the buckle 3, and a limiting piece is provided at the lower part. The front end of the first hinge piece 301 is recessed downward to form a first limiting portion 302, and the front end of the limiting piece is bent upward to form a second limiting portion.

[0040] Preferably, the first limiting portion 302 is snap-fitted and fixed with the groove 101 of the upper support 11, and the second limiting portion is snap-fitted and fixed with the groove 101 of the lower support 12, so that the buckle 3 is fixed in the fluent strip groove 101.

[0041] Preferably, a second hinge piece 201 is provided at the upper part of the connecting plate 2, and the first hinge piece 301 and the second hinge piece 201 are rotationally connected by a hinge shaft.

[0042] Preferably, a buffer washer 7 is provided between the adjusting nut 6 and the spring 5 to prevent loosening and protect the components.

[0043] Preferably, the support screw 4 has threads.

[0044] When materials are placed on the plate chain, in order to prevent the materials from falling, conveying devices 1 such as fluent strips need to be added on the side for assistance. However, when placing materials with easily deformable surfaces, if the materials are placed improperly and there is a certain angle when contacting the conveying device 1, the contact area between the product and the surface of the conveying device 1 is too small, and the phenomenon of contact surface deformation and scratching is likely to occur. By using this auxiliary mechanism, the angle of the conveying device 1 can be automatically adjusted to reduce the deformation and wear of the product surface.

[0045] In addition, a spring 5 with an appropriate elastic force is selected according to the weight of the materials and nested and installed at a specific position between the connecting plate 2 and the buckle 3. At the same time, the adjusting nut 6 can be used to adjust and fix the maximum angle of this auxiliary mechanism. Adjust the adjusting nut 6 according to actual requirements to obtain the allowable upper limit of the angle, which is the starting position of this device.

[0046] Under the action of this auxiliary adjustment mechanism, it is also possible to make some conveying devices 1 adapt to materials of different sizes, models, and weights. By adaptively adjusting the angle between the materials and the conveying device 1, the contact area between the materials and the conveying device 1 can be increased, the error tolerance rate during the product placement process can be improved, and the surface wear and indentation of the product during the conveying process of the materials on the conveying device 1 can be reduced or eliminated.

[0047] Figure 3To assist in adjusting the force motion diagram of the mechanism, the solid line portion is the starting position, the dotted line portion is the maximum deformation state of the mechanism, and the range of the force motion path of the mechanism is between the two.

[0048] Figure 4 This is the force analysis without external force, θ is the angle of the mechanism, mainly the gravity G of the smooth bar and the elastic force F given by the spring 弹 , and the support force F given by the buckle n Maintain balance. The equilibrium equations in this state are G cosθ=F n , G sinθ=F 弹 =-kx1.

[0049] Figure 5 For force analysis under material pressure, a pressure F is added compared to the case without pressure. 压 The equilibrium equations in this state are: G cosθ=F n ,G sinθ+F 压 cosθ=F 弹 =-kx2.

[0050] The working principle of this embodiment: After the auxiliary adjustment mechanism is installed, when the object is conveyed, if the product tilts toward the conveying device, it will apply pressure to the conveying device, and the spring on the supporting screw of the auxiliary adjustment mechanism will be compressed. The angle of the conveying device will change with the compression of the spring. Since the connecting plate of the mechanism is fixed and the upper part is connected by a hinge, when the buckle is clamped in the groove of the conveying device and fixed, the angle of the conveying device will be consistent with the inclination angle of the material, so that the contact surface between the material and the conveying device is increased, thereby increasing the force area, increasing the material contact buffer, and reducing damage to the material. After the material is transported, the spring automatically returns to the starting position to realize real-time adjustment of the angle.

[0051] The main functions of this implementation case are:

[0052] 1. Through simple mechanisms such as springs and hinges, the conveying device can adapt to incoming materials at different angles, maximizing the contact area between the material and the conveying device and reducing damage to the material surface caused by uneven force.

[0053] 2. The mechanism is supported by springs and is suitable for materials of different weights. The maximum angle of the conveying device, that is, the maximum allowable limit, can be controlled by the nut at the back. It is easy to debug and has wide adaptability.

[0054] 3. The structure is simple, easy to implement and manufacture, and convenient to install. After forming, it can be used by simply nesting it on the conveying device. It is energy-saving, economical, environmentally friendly and has a low cost.

[0055] Example 3:

[0056] like Figure 1-Figure 5 As shown, this embodiment discloses an auxiliary adjustment mechanism applicable to multiple force angles, which differs from the first and second embodiments in that:

[0057] Preferably, a distance-adjusting nut is also provided between the spring 5 and the buckle 3 , and the support screw 4 is fixed by the distance-adjusting nuts 6 on the inner and outer sides of the connecting plate 2 , thereby fixing the angle of the mechanism.

[0058] Preferably, a buffer washer is provided between the spring 5 and the buckle 3. When the required angle is very small or the connecting plate is parallel to the buckle, the distance adjusting nut on the inner side of the connecting plate 2 is replaced by the buffer washer.

[0059] Preferably, the buffer gasket is a rubber gasket.

[0060] The improvement of this embodiment is that by adding a distance-adjusting nut or a buffer washer on the inner side of the connecting plate, the buffer angle of the fixing mechanism is adapted to a conveying device that requires fixed-angle transportation.

[0061] Example 4:

[0062] like Figure 1 、 Figure 3-Figure 6 As shown, this embodiment discloses an auxiliary adjustment mechanism applicable to multiple force angles. The difference between this embodiment and the first to third embodiments is that the mechanism is applied to a safety anti-pinch device.

[0063] Specifically, if Figure 6 As shown in the figure, taking the escalator apron anti-pinch device as an example, the traditional apron anti-pinch device is fixedly installed on the gap between the escalator handrail wall and the stairs to remove dust and prevent pinching. The gap between the apron and the stairs poses a risk of clothes, children's fingers, shoes, etc. being caught. In this regard, the auxiliary adjustment mechanism can avoid such risks. The specific working method is as follows:

[0064] The conveying device is an apron plate, and the connecting plate 2 is fixed to the elevator handrail wall. The apron plate is provided with a groove, and the buckle 3 is engaged with the groove to fix the apron plate and the buckle 3. After the adjusting nut 6 adjusts the angle, the buckle 3 is fixed. When the passenger accidentally touches the plate brush, the buckle 3 is forced to shrink inward, reducing the gap with the step, without causing the apron plate brush 15 to retract too much, avoiding the risk of pinching. Since the buckle 3 is engaged with the apron plate brush 15, it is easy to replace the apron plate brush 15.

[0065] The improvement of this embodiment is that the auxiliary adjustment mechanism is used to replace the traditional apron plate anti-pinch device to prevent clothes or children's fingers, shoes, etc. from being pinched, and it is also convenient to replace the apron plate brush.
