Description
Technical Field
[0001] The utility model relates to the field of linear moulds, in particular to a fully enclosed European standard direct-connected belt mould. Background Art
[0002] The European standard linear module can also be called the European standard linear slide. It can mainly output linear reciprocating motion and is widely used in the fields of intelligent manufacturing and automation.
[0003] A common structure of a linear module is a slide plus a linear transmission structure, and the linear transmission mechanism is basically half-wrapped inside by the profile, while the slide is exposed to the outside in order to be fixed with external components. The slide and the linear transmission mechanism must be fixedly connected.
[0004] In actual use, this brings up a technical problem. Because the working environment of the linear module is diverse, there may be a lot of impurities in some working scenarios. If the impurities fall into the precise linear transmission mechanism, it will greatly reduce the service life and accuracy of the linear module. However, the linear transmission mechanism must be semi-exposed to the outside, because the slide needs to move, and the connection between the slide and the linear transmission structure naturally follows the movement as a whole, so this path space needs to be given up. If the cover is used to avoid external impurities, there will be interference with the movement of the slide. Utility Model Content
[0005] The problem to be solved by the utility model is to provide a fully enclosed European standard direct-connected belt module, the slide seat convex outward and guides the cover belt to make a slightly convex deformation, and the cover belt still covers the place where the slide seat is not, and when the slide seat passes, the cover belt can be adaptively lifted to achieve a dynamic sealing effect, which can prevent external impurities from entering and damaging the module.
[0006] In order to solve the above problems, the utility model provides a fully enclosed European standard direct-connected belt module. In order to achieve the above purpose, the technical solution adopted by the utility model to solve its technical problems is:
[0007] The fully enclosed European standard direct-connected belt module includes: an action mechanism, including a transmission belt driven by a rotating motor, the transmission belt is located in the cavity profile; a covering belt, arranged in parallel with the cavity profile and covering the side opening of the cavity profile, and the two ends of the covering belt itself are fixed to the cavity profile; a slide, passing through the side opening of the cavity profile and fixed to the transmission belt, the transmission belt drives the slide to perform linear reciprocating motion along the length direction of the cavity profile itself; the top of the slide itself has a middle block with a high middle and low ends, and rollers are installed at both ends of the slide, the axis of the roller itself is perpendicular to the length direction of the cavity profile itself, and the flexible covering belt passes between the roller and the middle block.
[0008] The beneficial effect of adopting the above technical solution is: this technical solution uses the covering belt to form a fully enclosed structure, which has a more beautiful appearance and effectively prevents foreign matter and impurities in the module operating environment from falling into the structure, thereby reducing the failure rate of the structure and increasing the service life of the module.
[0009] The destructive load test proves that this technical solution is more reasonable than the previous design. To a certain extent, it reduces the investment cost of the enterprise and brings higher economic benefits to customers.
[0010] At the same time, the covering has a sealing and protective effect, but the technical solution also overcomes the interference problem between the traditional slide and the covering belt when moving.
[0011] First, the cover belt is flexible and can deform along with the convex top surface of the slide. The slide is actually always under the cover belt and in contact with the bottom surface of the cover belt.
[0012] Secondly, the convex shape of the slide seat ensures that the cover belt deforms slightly convexly as the slide seat moves, and this deformation changes all the time with the slide seat.
[0013] Finally, the roller also plays a role. The roller is in contact with the bottom surface of the cover belt, and the resistance caused by sliding friction is low. The main function of the roller is to ensure the downward pressure shaping of the cover belt, so that the cover belt that does not contact the slide seat can still basically maintain contact with the cavity profile to avoid gaps.
[0014] As a further improvement of the utility model, the slide seat includes a lower supporting block and a sliding block fixed to each other, the lower supporting block includes a middle block and side strip blocks, the side strip blocks are fixed on both sides of the middle block, the top surface height of the side strip blocks themselves is higher than the top surface of the middle block themselves, and the middle block and the side strip blocks form a recessed groove for the covering belt to pass through.
[0015] The beneficial effect of adopting the above technical solution is that the cover belt always shuttles in the concave groove, which plays a role in limiting the left and right directions of the cover belt. The side strips extending from both sides also facilitate the fixing of the slide seat and the external components.
[0016] As a further improvement of the utility model, the top surface of the middle block itself includes a horizontal top surface and a convex sliding surface. The two convex sliding surfaces are symmetrically located at both ends of the horizontal top surface, and the convex sliding surface is tangentially connected to the horizontal top surface.
[0017] The beneficial effects of adopting the above technical solution are: the overall transition is rounded, so that the concave and convex shape of the covering belt is not too bent, and the friction and extrusion between the covering belt and the sliding seat is not too large.
[0018] As a further improvement of the utility model, from the center of the lower supporting block itself to the two ends, the height drop value of the convex sliding surface itself increases successively within each unit horizontal distance.
[0019] The beneficial effect of adopting the above technical solution is that the convex-slip surface guides the deformation of each part of the cover belt, and the concave-convex degree of the convex-slip surface should avoid damaging the cover belt.
[0020] As a further improvement of the present invention, the roller is arranged horizontally, and the bottom surface of the roller is lower than the height of the horizontal top surface.
[0021] The beneficial effect of adopting the above technical solution is: ensuring the downward pressing effect of the roller on the cover belt.
[0022] As a further improvement of the utility model, the lower supporting block has outer protrusions at both ends, and a notch is formed between the outer protrusions and the side strips on both sides, and the width of the outer protrusions is smaller than the axial length of the roller.
[0023] The beneficial effect of adopting the above technical solution is: it is equivalent to the lower supporting block being narrow at both ends. The purpose of this design is to ensure that when the covering belt just contacts the two ends of the lower supporting block, the two edges of the covering belt are not supported below, and the two edges of the covering belt only tend to droop downward, and have no tendency to warp upward, so the sealing covering effect is better.
[0024] As a further improvement of the utility model, the top of the side bar itself is horizontal, a cover plate is suspended between the two side bars, the vertical distance between the cover plate and the horizontal top plate of the lower support block is greater than the thickness of the covering belt, and the roller is located below the cover plate.
[0025] The beneficial effect of adopting the above technical solution is that the cover plate and the side strip block provide a large fixing surface for the top of the slide seat, and there is no need to worry about the external components interfering with the cover belt.
[0026] As a further improvement of the utility model, both ends of the cover plate itself are provided with lower folding edges extending downward as a whole, and the height at which the bottom of the lower folding edge itself is located is flush with the height at which the bottom of the roller is located.
[0027] The beneficial effect of adopting the above technical solution is that the lower folded edge plays a role of further covering the roller to prevent external objects from being entangled in the roller.
[0028] As a further improvement of the present invention, the width of the covering strip is not less than the width of the side opening of the cavity profile, and both ends of the covering strip are fixed to the cavity profile by means of edge pressing strips.
[0029] The beneficial effect of adopting the above technical solution is that the edge pressing strip can ensure that the covering belt is basically flush, but it does not affect its local moderate convex or concave shape.
[0030] As a further improvement of the utility model, the slider is movably equipped with a linear guide rail, the linear guide rail is located in the cavity profile, the rotating motor is coaxially fixed with a driving wheel, the inner ring of the transmission belt contacts the driving wheel and the driven wheel, and the driving wheel and the driven wheel are both synchronous wheels.
[0031] The beneficial effect of adopting the above technical solution is that the module is a linear reciprocating walking mechanism in which the synchronous belt is driven by the synchronous wheel. BRIEF DESCRIPTION OF THE DRAWINGS

The two ends of the cover belt 6 itself are fixed to the cavity profile 8.
[0046] The beneficial effects of adopting the above technical solution are: this technical solution uses the covering belt to form a fully enclosed structure, which has a more beautiful appearance and effectively prevents foreign matter and impurities in the module operating environment from falling into the structure, thereby reducing the failure rate of the structure and increasing the service life of the module. The destructive load test proves that this technical solution is more reasonable than the previous design. To a certain extent, the enterprise has less investment cost and the customer has higher economic benefits. At the same time, the covering has a sealing protection effect, but the technical solution also overcomes the interference problem between the traditional slide and the covering belt when the slide moves. First, the covering belt is flexible and can be deformed with the convex top surface of the slide. The slide is actually always under the covering belt and in contact with the bottom surface of the covering belt. Secondly, the convex shape of the slide ensures that the covering belt is slightly convexly deformed as the slide moves, and this deformation changes with the slide. Finally, the roller also plays a role. The roller is in contact with the bottom surface of the cover belt, and the resistance caused by sliding friction is low. The main function of the roller is to ensure the downward pressure shaping of the cover belt, so that the cover belt that does not contact the slide seat can still basically maintain contact with the cavity profile to avoid gaps.
[0047] In other embodiments of the utility model, the slide seat 9 includes a lower support block 11 and a slider 10 which are fixed to each other. The lower support block 11 includes a middle block 1102 and a side strip block 1101. The side strip blocks 1101 are fixed on both sides of the middle block 1102. The top surface height of the side strip block 1101 is higher than the top surface of the middle block 1102. The middle block 1102 and the side strip block 1101 form a recessed groove 1105 for the covering belt to pass through.
[0048] The beneficial effect of adopting the above technical solution is that the cover belt always shuttles in the concave groove, which plays a role in limiting the left and right directions of the cover belt. The side strips extending from both sides also facilitate the fixing of the slide seat and the external components.
[0049] like Figure 2 As shown, in some other embodiments of the present invention, the top surface of the middle block 1102 itself includes a horizontal top surface 1107 and a convex sliding surface 1106. The two convex sliding surfaces 1106 are symmetrically located at both ends of the horizontal top surface 1107, and the convex sliding surfaces 1106 and the horizontal top surface 1107 form a tangent connection.
[0050] The beneficial effects of adopting the above technical solution are: the overall transition is rounded, so that the concave and convex shape of the covering belt is not too bent, and the friction and extrusion between the covering belt and the sliding seat is not too large.
[0051] In other embodiments of the present invention, from the center of the lower supporting block 11 to both ends, the height drop value of the convex sliding surface 1106 increases successively within each unit horizontal distance.
[0052] The beneficial effect of adopting the above technical solution is that the convex-slip surface guides the deformation of each part of the cover belt, and the concave-convex degree of the convex-slip surface should avoid damaging the cover belt.

[0054] The beneficial effect of adopting the above technical solution is: ensuring the downward pressing effect of the roller on the cover belt.
[0055] In some other embodiments of the present invention, the lower support block 11 has outer protrusions 1103 at both ends, and a notch 1104 is formed between the outer protrusions 1103 and the side strips 1101 on both sides. The width of the outer protrusions 1103 is smaller than the axial length of the roller 12.
[0056] The beneficial effect of adopting the above technical solution is: it is equivalent to the lower supporting block being narrow at both ends.

[0057] In other embodiments of the utility model, the top of the side strip 1101 itself is horizontal, and a cover plate 13 is suspended between the two side strips 1101. The vertical distance between the cover plate 13 and the horizontal top plate 1107 of the lower support block 11 is greater than the thickness of the covering belt 6, and the roller 12 is located below the cover plate 13.
[0058] The beneficial effect of adopting the above technical solution is that the cover plate and the side strip block provide a large fixing surface for the top of the slide seat, and there is no need to worry about the external components interfering with the cover belt.

[0067] Because of mechanical design conventions and design software, Figure 2 , Figure 7 The covering belt 6 in the figure is in a straight state, but in fact, the covering belt 6 has a deformed convex shape.
