[0036] The invention discloses a wrapping mechanism, which comprises: a first template 1, a second template 2, a product positioning seat 3, a pressing block assembly 4 and a sliding block assembly 5.

[0037] Optionally, the first template 1 and the second template 2 are two square plates parallel to each other.

[0038] The product positioning seat 3 is arranged on the second template 2 .

[0039] Optionally, the product positioning seat 3 is provided with a contour positioning groove 31, which is designed according to the shape of the product 10 to fix and position the product 10. In this embodiment, the product 10 is a square structure, including a product to be edged and an edged product, the product to be edged is placed on the product positioning seat 3, the edged product is covered on the product to be edged, and the final product is formed by edge joining, and all four sides of the product 10 need to be edged; optionally, in other embodiments, only one side, two sides or three sides may need to be edged, and the edge joining mechanism in this embodiment can adapt to the edge of the product 10 in this embodiment, and can also be fine-tuned according to the situation of the edge of the product 10 to achieve edge joining with structures such as arcs and bevels.

[0040] Optionally, in this embodiment, at least three support components 6 are further arranged between the product positioning seat 3 and the second template 2. The support component 6 includes a coaxially arranged hinge pin 61, a first gasket 62, a third elastic member 63 and a first bushing 64. The two ends of the hinge pin 61 are respectively fixed on the second template 2 and the product positioning seat 3. The first bushing 64 is sleeved on the part of the hinge pin 61 located in the second template 2. The first gasket 62 is sleeved on the part of the hinge pin 61 located in the product positioning seat 3. The third elastic member 63 is sandwiched between the second template 2 and the product positioning seat 3. Optionally, the third elastic member 63 can be a compression spring. The advantage of such a setting is that when the wrapping is completed, the force of the first template 1 pressing on the product positioning seat 3 and the product 10 is reversed, for example, upward, so the third elastic member 63 has a reset function, which will lift the product positioning seat 3 and then lift the product 10, so that the product 10 is separated from the pressing block assembly 4, and the knife jam problem can be well solved.

[0041] Optionally, in this embodiment, the product positioning seat 3 is fixed to the second template 2 via a fixing plate 23 , that is, the supporting assembly 6 is arranged on the fixing plate 23 , which will not be described in detail again.

[0042] The first template 1 is movably connected to the second template 2, and the first template 1 and the second template 2 can move closer to or farther away from each other under external action.

[0043] Optionally, in this embodiment, the first template 1 and the second template 2 are movably connected via a guide shaft 121 and a guide sleeve 122, and the portion of the guide shaft 121 between the first template 1 and the second template 2 is also sleeved with a second elastic member 123 and a buffer member 124. Optionally, the second elastic member 123 is a cylindrical spring. Optionally, the buffer member 124 is a second gasket.

[0044] Optionally, in this embodiment, a mold handle 11 is provided on the side of the first template 1 away from the second template 2. The mold handle 11 can be connected to an external power structure, and the external power structure drives the first template 1 to move in a direction close to or away from the second template 2. For example, when the external power structure drives the first template 1 to move in a direction close to the second template 2, for example, in this embodiment, it moves downward. During the movement, the first template 1 gradually contacts the product 10 placed on the product positioning seat 3 until a certain pressure is applied to the product 10. Optionally, the second elastic member 123 is sleeved on one end of the guide shaft 121 close to the second template 2, and the buffer member 124 is sleeved on one end close to the first template 1. Both the second elastic member 123 and the buffer member 124 play a buffering role to prevent the first template 1 from directly contacting the product 10 and crushing the product 10. Optionally, in this embodiment, the mold handle 11 is provided on the first template 1 through the mold handle fixing block 111. Of course, the mold handle 11 can also be provided on the second template 2, and the second template 2 is driven to move in a direction close to or away from the first template 1. Optionally, the external power structure may be a servo electric cylinder.

[0045] The pressing block assembly 4 is arranged on the periphery of the product positioning seat 3 .

[0046] Optionally, in this embodiment, the pressing block assembly 4 includes a pressing block 41 , and the pressing block 41 is fixed on the second template 2 .

[0047] Specifically, the pressing block 41 is provided with a second inclined surface 411, which is arranged on the side of the pressing block 41 facing the product positioning seat 3, and the second inclined surface 411 gradually moves away from the central axis of the product positioning seat 3 in the first direction. In this embodiment, the first template 1 and the second template 2 are arranged in the up-down direction, and the central axis of the product positioning seat 3 is the vertical direction. The distance between the second inclined surface 411 and the central axis of the product positioning seat 3 is the distance between each point on the second inclined surface 411 and the vertical direction, which is actually a horizontal distance. In this embodiment, the first direction is the direction from the second template 2 to the first template 1.

[0048] Optionally, the pressing block assembly 4 includes at least two, which are evenly arranged around the periphery of the product positioning seat 3. For example, in this embodiment, the product 10 is a quadrilateral structure, and all four sides need to be wrapped. The pressing block assembly 4 includes four, which are respectively arranged on the outside of the product positioning seat 3, corresponding to the four sides of the product positioning seat 3 in different directions. This design can wrap the four sides of the product 10 at one time.

[0049] Of course, in other embodiments, three pressing block assemblies 4 may be provided, or even five, six, seven, eight, etc., depending on the number of sides of the product 10 .

[0050] Optionally, in this embodiment, the four sides of the product 10 each include two side edges that are spaced apart from each other. Therefore, each pressing block assembly 4 includes two pressing blocks 41 , and the pressing blocks 41 are arranged corresponding to each side edge that needs to be wrapped.

[0051] The slider assembly 5 is arranged on the first template 1 .

[0052] Optionally, the slider assembly 5 includes at least two slider assemblies, which are arranged in a one-to-one correspondence with the pressing block assembly 4. That is, the slider assembly 5 and the pressing block assembly 4 are not only the same in number, but also in a one-to-one correspondence in position.

[0053] The slider assembly 5 includes a slider 51 , which is slidably disposed on the first template 1 and can move toward the product positioning seat 3 .

[0054] Furthermore, the slider assembly 5 includes a mounting block 52, which is fixed to the first template 1; optionally, in this embodiment, the mounting block 52 can be fixed to the first template 1 by a fastener (not shown); optionally, the fastener can be a structure such as a screw.

[0055] The mounting block 52 is provided with a slide groove 521 for mounting the slider 51 on one side facing the first template 1, the slide groove 521 is arranged along the second direction, the slider 51 is slidably placed in the slide groove 521, and can linearly reciprocate along the second direction in the slide groove 521, wherein the second direction is a direction perpendicular to the side of the product 10 placed on the product positioning seat 3. For example, in this embodiment, the slide groove 521 is arranged in the horizontal direction, the slider 51 is also arranged in the horizontal direction, and the slider 51 can slide in the slide groove 521 in the horizontal direction.

[0056] The sliding block 51 extends laterally from one end of the sliding block 51 toward the product positioning seat 3 to point to the product 10 placed on the product positioning seat 3. The portion of the sliding block 51 that can contact and wrap the product 10 is called a knife portion. In the present embodiment, the knife portion of the sliding block 51 is the end that extends out of the mounting block 52 and points to the product 10 placed on the product positioning seat 3; accordingly, the slide groove 521 of the mounting block 52 is arranged to penetrate the mounting block 52 at the end of the sliding block 51 facing the product positioning seat 3; the end of the sliding block 51 away from the product positioning seat 3 cannot exceed the mounting block 52, and accordingly, the slide groove 521 of the mounting block 52 is arranged not to penetrate the mounting block 52 at the end of the sliding block 51 away from the product positioning seat 3. Such an arrangement can prevent the sliding block 51 from slipping out of the mounting block 52.

[0057] Specifically, the slider 51 is provided with a through hole 511 for the pressure block 41 to pass through, and a first inclined surface 5111 is provided on a hole wall of the through hole 511 adjacent to the product positioning seat 3. The first inclined surface 5111 gradually moves away from the central axis of the product positioning seat 3 along the first direction.

[0058] In this embodiment, the first inclined surface 5111 and the second inclined surface 411 are arranged in a one-to-one correspondence and can contact each other to generate pressure directed to the side of the product 10 placed on the product positioning seat 3. Specifically, the first template 1 is pressed straight down toward the second template 2 under the action of an external force, and the first inclined surface 5111 arranged on the first template 1 and the second inclined surface 411 on the second template 2 are in surface-to-surface contact, thereby generating a positive pressure perpendicular to the first inclined surface 5111, which can be decomposed into a lateral pressure and a vertical pressure, and the lateral pressure is directed toward the product positioning seat 3, so the slider 51 moves straight toward the product positioning seat 3 under the action of the lateral pressure to achieve a wrapping action.

[0059] It has been verified through experiments that when the inclination angle of the first bevel 5111 and the second bevel 411 is 60 degrees, the wrapping effect of the entire structure is optimal, and when it is 45 degrees, the friction between the first bevel 5111 and the second bevel 411 is maximum. Optionally, the inclination angle can be selected to be between 45 and 70 degrees.

[0060] Furthermore, a pre-stress block 13 is provided at a position of the first template 1 facing the product positioning seat 3. The first template 1 is aligned with the pre-stress block 13 and is connected to the pre-stress block 13 through a pre-stress elastic component 15. The pre-stress elastic component 15 includes a pre-stress rod 151, a pre-stress sleeve 152 and a pre-stress elastic member 153. One end of the pre-stress rod 151 is located in the first template 1, and the other end extends into the pre-stress block 13. The pre-stress sleeve 152 is located in the first template 1 and is sleeved on the outside of the pre-stress rod 151. One end of the pre-stress elastic member 153 extends into the pre-stress rod 151, and the other end abuts against a mold handle fixing block 111 arranged on the side of the first template 1 away from the pre-stress block 13. The arrangement of the pre-stress elastic component 15 and the pre-stress block 13 can keep the product 10 in the product positioning groove 3 after the encapsulation is completed to avoid adhesion to the pre-stress block 13.

[0061] Further, in order to realize the reset of the slider 51, a second reset assembly 9 is provided at one end of the slider 51 away from the central axis of the product positioning seat 3. The second reset assembly 9 includes a second rod-shaped member 91 and a second reset member 92. One end of the second rod-shaped member 91 is fixed on the slider 51, and the other end extends out of the mounting block 52 and is provided with a convex shoulder 911. The second reset member 92 is sleeved on the second rod-shaped member 91, and the two ends respectively abut against the outer side of the mounting block 52 and the convex shoulder 911. When the external force applied to the first template 1 changes direction, for example, upward, the first template 1 is reset, and at this time, the first inclined surface 5111 is away from the second inclined surface 411, and the positive pressure generated between the first inclined surface 5111 and the second inclined surface 411 gradually disappears, so that the slider 51 is reset under the action of the second reset assembly 9. Optionally, the second rod-shaped member 91 can be a modified screw, and the second reset member 92 can be a cylindrical compression spring.

[0062] The wrapping mechanism in this embodiment controls the first template 1 or the second template 2 to move closer to each other, thereby pressing the product 10 on the product positioning seat 3. On the other hand, the first inclined surface 5111 and the second inclined surface 411 contact each other, thereby generating pressure directed to the side of the product 10 placed on the product positioning seat 3, thereby achieving wrapping. This structure only requires one power source, with low cost, simple control, and simple structure. Under the action of one power source, multiple sides of the product 10 can be wrapped at the same time, saving a large part of time, speeding up the rhythm, and improving the wrapping efficiency.

[0063] Preferably, in this embodiment, the hemming product of the product 10 is an aluminum structure, and the knife portion of the slider 51 needs to resist the aluminum structure and press it inwardly in the lower direction of the product 10 to complete the curling hemming. After the hemming is completed, the knife portion of the slider 51 is easily stuck. Therefore, further, in this embodiment:

[0064] There is a preset distance between the mounting block 52 and the first template 1 , and a first resetting component 7 is arranged between the mounting block 52 and the first template 1 .

[0065] Optionally, the reserved distance can be 0.5mm, or other values, depending on the actual situation. In this embodiment, the mounting block 52 is fixed to the first template 1 by screws, and the reserved distance can be controlled to reach the required value by controlling the depth of the screws inserted into the first template 1.

[0066] Optionally, the first reset assembly 7 includes a first rod-shaped member 71 and a first reset member 72, wherein both ends of the first rod-shaped member 71 are respectively fixed to the first template 1 and the mounting block 52, and the first reset member 72 is clamped on the first template 1 and the mounting block 52. Optionally, the first rod-shaped member 71 may be a modified screw, and the first reset member 72 may be a cylindrical compression spring.

[0067] The pressing block assembly 4 also includes a limit block 43 for limiting the mounting block 52. The limit block 43 is sleeved on the outside of the pressing block 41, and the other end is fixedly connected to the second template 2 through the first elastic component 8. The elastic force of the first elastic component 8 is greater than the elastic force of the first reset component 7.

[0068] Optionally, the first elastic component 8 includes a first columnar member 81 and a first elastic member 82, one end of the first columnar member 81 is fixed on the second template 2, and the other end is fixed on the limit block 43, and the first elastic member 82 is sandwiched between the limit block 43 and the second template 2. In the embodiment with a fixed plate 23, one end of the first columnar member 81 is fixed on the fixed plate 23, and the first elastic member 82 is sandwiched between the limit block 43 and the fixed plate 23. Optionally, the first columnar member 81 can be a modified screw, and the second reset member 92 can be a rectangular spring. Generally speaking, the elastic force of the rectangular spring is greater than that of the cylindrical spring.

[0069] In the wrapping mechanism of this embodiment, when the first template 1 is pressed down, the limit block 43 first contacts and holds the mounting block 52, and continues to press down. The mounting block 52 cannot continue to move downward under the action of the limit block 43, so the reserved distance is filled, and the mounting block 52 is in close contact with the first template 1. At this time, the upper end surface of the knife part of the slider 51 that wraps the product 10 is close to the part of the product 10 that needs to be wrapped, so as to achieve the wrapping. The advantage of such a setting is that the wrapping effect is better. When the external force is removed, the first template 1 moves upward to reset, and the positive pressure generated between the first inclined surface 5111 and the second inclined surface 411 slowly decreases. When the positive pressure is less than the elastic force of the first reset component 7, the slider 51 will be pushed outward under the action of the first reset component 7, that is, pushed in the direction close to the second template 2, so that the upper end surface of the slider 51 is separated from the wrapping part of the product 10, which can well solve the problem of knife jamming.

[0070] Furthermore, a sensor is included, which is used to detect whether there is a product 10 still adhering to the product positioning seat 3 or the clamping knife to avoid problems. Optionally, the sensor can be a photoelectric sensor, which is arranged on the first template 1, specifically arranged at two opposite diagonal corners corresponding to the product positioning seat 3.

[0071] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
