Description

Technical Field

[0001] This utility model relates to the technical field of handles, and more particularly to a handle pressure-holding mechanism. Background Technology

[0002] Handles typically have connecting parts at both ends so that when the handle is connected to the box body, the connecting parts can be housed within the box body to enable the handle's lifting function. Currently, after the connecting parts are formed at both ends by adhesive folding, the handle needs to be conveyed by a conveyor mechanism to complete the unloading process. In related technologies, due to the short forming time of the connecting parts, the folded parts may separate and delaminate during the conveying and unloading process, thus affecting the production efficiency of the handles. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a handle pressure-holding mechanism that can maintain the shape of the folded part during transportation, thereby improving the production efficiency of handles.

[0004] According to a first aspect of the present invention, the handle pressure-holding mechanism includes: a support platform, a conveyor belt, and a pressure-holding component.

[0005] A conveyor belt is connected to the support platform and is used to transport the handle along a first direction. The pressure holding assembly includes a drive member, a pressure holding plate, and a support plate. The support plate is connected to the support platform, and the support plates are respectively provided on both sides of the conveyor belt along the first direction. The pressure holding plate and the support plate are spaced apart to jointly clamp the connecting parts at both ends of the handle. The drive member is connected to the pressure holding plate and drives the pressure holding plate to move, thereby changing the pressure holding distance between the pressure holding plate and the support plate.

[0006] The handle pressure-holding mechanism according to the embodiments of this utility model has at least the following beneficial effects: By spaced apart the support plate and the pressure-holding plate, a pressure-holding gap is formed between them. During the forming of the handle's connecting part for conveying and discharging materials, the connecting part of the handle can be accommodated within the pressure-holding gap between the support plate and the pressure-holding plate to further strengthen the folding strength of the connecting part and prevent separation of the folded portion. Furthermore, by changing the distance between the pressure-holding plate and the support plate through the driving component, the handle pressure-holding mechanism can be adapted to connecting parts of different thicknesses.

[0007] According to some embodiments of the present invention, the pressure holding plate includes a first plate and a second plate, the first plate and the second plate respectively corresponding to the driving member, the support plate and the first plate are spaced apart along the second direction to jointly define a first pressure holding cavity, the support plate and the second plate are spaced apart along the third direction to jointly define a second pressure holding cavity, the first pressure holding cavity and the second pressure holding cavity are connected, and the first direction, the second direction and the third direction are perpendicular to each other.

[0008] According to some embodiments of the present invention, at least a portion of the second plate is spaced apart from the first plate along a second direction, and a third pressure-holding cavity is defined between the first plate and the second plate, the third pressure-holding cavity connecting the first pressure-holding cavity and the second pressure-holding cavity.

[0011] According to some embodiments of the present invention, the pressure holding assembly further includes a lifting block, which is connected to the second plate. Each of the pressure holding wheel sets and the first plate are provided with a lifting block along a third direction. The lifting block has an inclined surface structure along a second direction on the side facing the corresponding pressure holding wheel set.

[0034] The handle pressure-holding mechanism of this utility model embodiment is described below with reference to the accompanying drawings. It should be noted that, for ease of description and understanding, the forward and backward direction is indicated as the first direction, the left and right direction as the second direction, and the up and down direction as the third direction.

[0035] This utility model embodiment provides a handle pressure-holding mechanism 100 for clamping the connecting part 210 of the handle 200, see reference. Figures 1 to 3 As shown, the handle pressure-holding mechanism 100 includes a support platform 110, a conveyor belt 120, and a pressure-holding assembly 130. The support platform 110 is the main body of the handle pressure-holding mechanism 100. The conveyor belt 120 is connected to and mounted on the support platform 110. The conveyor belt 120 is used to convey the formed handle 200 in the front-to-back direction. The pressure-holding assembly 130 includes a drive member 131, a pressure-holding plate 132, and a support plate 133. Since the two ends of the handle 200 form connecting portions 210 by folding, and the support plate 133 is used to support the connecting portions 210 of the handle 200, in this embodiment, there are two support plates 133. The two support plates 133 are connected to the support platform 110 and are arranged on both sides of the conveyor belt 120 in the front-to-back direction, i.e., on the left and right sides of the conveyor belt 120. In other embodiments, the number of support plates 133 may be one, three, or four, or other numerical features, as long as the support plates 133 can support the connecting portions 210 at both ends of the handle 200.

[0036] Furthermore, the pressure holding plate 132 is disposed circumferentially around the support plate 133 along the front-to-back direction, and the pressure holding plate 132 and the support plate 133 are spaced apart, defining a pressure holding gap between them. When the conveyor belt 120 conveys the folded handle 200 to the handle pressure holding mechanism 100, the connecting part 210 of the handle 200 will be located within the pressure holding gap between the pressure holding plate 132 and the support plate 133, thereby achieving the pressure holding effect of the connecting part 210. The driving member 131 is connected to the pressure holding plate 132, and the driving member 131 can drive the pressure holding plate 132 to move relative to the support plate 133, changing the pressure holding gap between the pressure holding plate 132 and the support plate 133, thereby changing the tightness of the pressure holding of the pressure holding plate 132 and the support plate 133 on the connecting part 210. At the same time, the driving member 131 can also adapt the pressure holding plate 132 and the support plate 133 to connecting parts 210 of different thicknesses.

[0037] Specifically, in one example, see Figures 1 to 5 As shown, the handle 200 includes a first adhesive surface 211, a second adhesive surface 212, a third adhesive surface 213, a fourth adhesive surface 214, and a fifth adhesive surface 215 connected in sequence. When the handle 200 is folded at both ends to form the connecting portion 210, the second adhesive surface 212 bends downward relative to the first adhesive surface 211, and then the third adhesive surface 213 folds upward relative to the second adhesive surface 212, so that a portion of the third adhesive surface 213 is connected and adhered to the second adhesive surface 212. The fourth adhesive surface 214 bends downward relative to the third adhesive surface 213 and adheres to the third adhesive surface 213, with the fourth adhesive surface 214 and the second adhesive surface 212 adhering to the same side of the third adhesive surface 213. The fifth adhesive surface 215 bends to the right relative to the fourth adhesive surface 214 to adhere to the first adhesive surface 211, thereby forming the connecting portion 210 of the handle 200.

[0038] After the connecting portion 210 of the handle 200 is formed, the handle 200 is driven by the conveyor belt 120 to be conveyed toward the pressure holding assembly 130. In this embodiment, there are multiple pressure holding plates 132. Since the connecting portion 210 has a fitting portion in both the vertical and horizontal directions, pressure holding plates 132 are provided on the upper, left, and right sides of the support plate 133, and the pressure holding distance formed by the support plate 133 and the pressure holding plates 132 is adapted to the fitting portion of the connecting portion 210. During pressure holding, the fitting portions of the first adhesive surface 211 and the fifth adhesive surface 215 are placed within the pressure holding distance in the vertical direction between the support plate 133 and the pressure holding plate 132, and the fitting portions of the second adhesive surface 212, the third adhesive surface 213, and the fourth adhesive surface 214 are placed within the pressure holding distance in the horizontal direction between the support plate 133 and the pressure holding plate 132. By pressing the mating parts with the support plate 133 and the pressure plate 132, the folded parts of the connecting part 210 will not separate or delaminate before being conveyed to the discharge port, thereby improving the production efficiency of the handle 200.

[0039] In related technologies, the connecting part 210 of the handle 200 is directly conveyed to the discharge port after forming to complete the discharge. This results in a short forming time for the connecting part 210, and the connection relationship of the folded parts is not yet stable, leading to the possibility of separation and delamination of the folded parts during the discharge process. After separation, the connecting part 210 needs to be refolded, thus affecting the production efficiency of the handle 200. In contrast to related technologies, the handle pressure-holding mechanism 100 of this embodiment uses a support plate 133 and a pressure-holding plate 132 spaced apart to form a pressure-holding gap. During the forming and discharge process of the connecting part 210 of the handle 200, the connecting part 210 can be accommodated within the pressure-holding gap between the support plate 133 and the pressure-holding plate 132 to further strengthen the folding strength of the connecting part 210 and prevent separation of the folded parts.

[0040] In some embodiments, see Figures 1 to 5 As shown, the pressure-holding plate 132 includes a first plate 1321 and a second plate 1322, each having a corresponding driving member 131. The first plate 1321 and the second plate 1322 change the pressure-holding distance with the support plate 133 via the driving member 131. The first plate 1321 and the support plate 133 are spaced apart in the left-right direction, with the number of support plates 133 matching the number of first plates 1321, together defining a first pressure-holding cavity 1323. The second plate 1322 and the support plate 133 are spaced apart in the up-down direction, together defining a second pressure-holding cavity 1324. The first pressure-holding cavity 1323 and the second pressure-holding cavity 1324 are connected, and both are used to accommodate the connecting portion 210 of the handle 200. The pressure-holding distance is the height of the pressure-holding cavity in the up-down direction or the width in the left-right direction.

[0041] Specifically, see Figures 1 to 5As shown, the handle 200 includes a carrying part 220 and a connecting part 210, with the connecting part 210 disposed at both ends of the carrying part 220. The carrying part 220 is placed on the conveyor belt 120. Support plates 133 are disposed on both sides of the conveyor belt 120. When the handle 200 is conveyed to the pressure holding assembly 130, the connecting part 210 will be placed on the support plate 133. Since the folded part of the handle 200 is attached in the vertical direction or in the horizontal direction, the first plate 1321 is disposed on the left and right sides of the support plate 133, so that the first plate 1321 and the support plate 133 define a first pressure holding cavity 1323 in the horizontal direction. After the handle 200 enters the pressure holding gap, the first pressure holding cavity 1323 can hold pressure on the left and right attached parts of the handle 200. Simultaneously, the second plate 1322 is positioned above the support plate 133, thereby defining a second pressure-holding cavity 1324 between the second plate 1322 and the support plate 133 in the vertical direction. This second pressure-holding cavity 1324 provides pressure to the upper and lower mating portions of the handle 200. This achieves overall pressure holding of the connecting portion 210, improving the connection strength of each adhesive surface of the handle 200.

[0042] Furthermore, in some embodiments, see [reference] Figure 3 As shown, the first plate 1321 and at least a portion of the second plate 1322 are spaced apart in the left-right direction. The first plate 1321 and the second plate 1322 together define a third pressure-holding cavity 1325, which connects the first pressure-holding cavity 1323 and the second pressure-holding cavity 1324.

[0043] Specifically, see Figures 3 to 5 As shown, after the connecting part 210 of the handle 200 is formed, taking the handle part 220 of the handle 200 as a reference, the third adhesive surface 213 will be attached to the second adhesive surface 212 and the fourth adhesive surface 214 on the upper and lower sides of the handle part 220, respectively. Since the second plate 1322 is located above the support plate 133 and the first plate 1321 is located on the left and right sides of the support plate 133, the second plate 1322 and the first plate 1321 can be spaced apart to define a new pressure-holding cavity, namely the third pressure-holding cavity 1325, in the left and right direction. The third pressure-holding cavity 1325 and the second pressure-holding cavity 1324 are distributed in the up and down direction. When the connecting part 210 of the handle 200 enters the pressure-holding gap, the second pressure-holding cavity 1324 will hold pressure on the bonding part of the second adhesive surface 212 and the third adhesive surface 213, and the third pressure-holding cavity 1325 will hold pressure on the bonding part of the second adhesive surface 212 and the fourth adhesive surface 214. This ensures that the folded bonding part of the connecting part 210 is subjected to pressure, thereby strengthening the bonding strength of the connecting part 210.

[0044] In some embodiments, see Figures 1 to 7As shown, the handle pressure holding mechanism 100 also includes a pressure holding wheel assembly 140. The second plate 1322 is provided with pressure holding wheel assemblies 140 on both sides along the front-back direction, i.e., the left and right sides. The pressure holding wheel assembly 140 is connected to the first plate 1321 and moves with the first plate 1321 in the left-right direction to switch between a first position and a second position. In the first position, the pressure holding wheel assembly 140 abuts against the side of the second plate 1322 away from the support plate 133 in the up-down direction. In the second position, the pressure holding wheel assembly 140 is separated from the second plate 1322.

[0045] Specifically, the first plate 1321 is driven by a driving member 131 (e.g., a motor, cylinder). The driving member 131 moves the first plate 1321 in the left-right direction relative to the support plate 133 to change the pressure-holding distance between the support plate 133 and the first plate 1321. Since the pressure-holding wheel assembly 140 is connected to the first plate 1321, the pressure-holding wheel assembly 140 also moves in the left-right direction along with the first plate 1321. When the first plate 1321 moves to the designated pressure-holding position, the pressure-holding wheel assembly 140 abuts against the second plate 1322 and applies downward pressure to the second plate 1322, thereby subjecting the connecting portion 210 to additional pressure, thus improving the pressure-holding effect.

[0046] When the pressure-holding assembly 130 finishes its pressure-holding operation, the first plate 1321 will move again in the left-right direction, at which point the pressure-holding roller assembly 140 will separate from the second plate 1322. Since the drive member 131 of the second plate 1322 controls its vertical movement, it applies external force in the vertical direction to drive the second plate 1322. When the second plate 1322 reaches the designated pressure-holding position, the drive member 131 stops moving, and the second plate 1322 remains stationary relative to the drive member 131. Separating the second plate 1322 and the pressure-holding roller assembly 140 during non-pressure-holding operations prevents the second plate 1322 from continuously being subjected to pressure from the pressure-holding roller assembly 140 and tending to move relative to the drive member 131, thus avoiding a loosening of the connection between the second plate 1322 and the drive member 131.

[0047] Furthermore, the pressure-holding roller assembly 140 is equipped with rollers, which abut against the second plate 1322 to apply pressure to the second plate 1322. By providing rollers, the contact mode between the pressure-holding roller assembly 140 and the second plate 1322 can be changed to rolling friction. By replacing sliding friction with rolling friction, wear between the pressure-holding roller assembly 140 and the second plate 1322 is reduced, and the service life is extended.

[0048] In some embodiments, see Figures 1 to 7As shown, multiple pressure-holding roller sets 140 are provided on the same side of the second plate 1322. These multiple pressure-holding roller sets 140 are spaced apart in the front-to-back direction. By providing multiple pressure-holding roller sets 140, sufficient pressure is ensured on the second plate 1322 in the vertical direction, thereby improving the pressure-holding effect of the connecting part 210. Simultaneously, the spaced arrangement of the multiple pressure-holding roller sets 140 in the front-to-back direction ensures that the pressure of the pressure-holding roller sets 140 is evenly applied to the second plate 1322, ensuring that the connecting part 210 receives balanced pressure throughout the pressure-holding process and avoiding quality problems caused by excessive or insufficient local pressure.

[0049] Furthermore, in some embodiments, see [reference] Figure 1 , Figure 6 and Figure 7 As shown, the pressure-holding assembly 130 also includes a lifting block 150, which is connected to the side of the second plate 1322 facing away from the support plate 133 in the vertical direction. The lifting block 150 is disposed between the second plate 1322 and the pressure-holding roller assembly 140, and the positions of the lifting block 150 and the pressure-holding roller assembly 140 correspond to each other. The number of lifting blocks 150 is matched with the number of pressure-holding roller assemblies 140, that is, a lifting block 150 is disposed between each pressure-holding roller assembly 140 and the second plate 1322. When the pressure holding roller assembly 140 applies pressure to the second plate 1322, the pressure holding roller assembly 140 will abut against the side of the lifting block 150 that is away from the second plate 1322 in the vertical direction. The pressure holding roller assembly 140 transmits pressure to the second plate 1322 through the lifting block 150, avoiding contact and friction between the second plate 1322 and the pressure holding roller assembly 140, thereby reducing the wear of the second plate 1322.

[0050] In this embodiment, since the pressure-holding roller assembly 140 is located on the left and right sides of the second plate 1322, and the movement direction of the pressure-holding roller assembly 140 is left and right, the lifting block 150 is provided with an inclined structure 151 on the side facing the corresponding pressure-holding roller assembly 140 in the left and right direction. The height of the inclined structure 151 gradually changes. When the pressure-holding roller assembly 140 contacts the lifting block 150, the pressure-holding roller assembly 140 will first abut against the side with the lower height of the inclined structure 151. As the pressure-holding roller assembly 140 gradually moves in the left and right direction, the height at which the pressure-holding roller assembly 140 abuts against the inclined structure 151 will become higher and higher, thereby increasing the pressure exerted by the pressure-holding roller assembly 140 on the second plate 1322, thus changing the pressure-holding intensity of the second plate 1322. The inclined structure 151 not only provides a transition structure when the pressure holding roller assembly 140 contacts the lifting block 150, preventing collisions between the pressure holding roller assembly 140 and the lifting block 150, but also changes the pressure holding pressure of the second plate 1322 by changing the contact position between the pressure holding roller assembly 140 and the lifting block 150, thereby improving the pressure holding effect of the connecting part 210.

[0051] In some embodiments, see Figure 1 and Figure 8 As shown, the handle pressure-holding mechanism 100 also includes clamping components 160, which are disposed on both sides of the conveyor belt 120 in the front-to-back direction, i.e., the left and right sides. The clamping components 160 are located upstream of the pressure-holding component 130. Since the connecting portion 210 is formed at both ends of the handle 220, the clamping components 160 on both sides of the conveyor belt 120 can clamp the connecting portion 210 after it is folded. At the same time, since the connecting portion 210 needs to be conveyed to the pressure-holding component 130 after it is formed, the clamping components 160 can keep the folded part of the connecting portion 210 in a close fit during the conveying process, thereby strengthening the connection strength of the folded part.

[0052] Specifically, the clamping assembly 160 includes a first clamping portion 161 and a second clamping portion 162, which are arranged vertically. The first clamping portion 161 and the second clamping portion 162 are used to clamp the mating portion of the first adhesive surface 211 and the fifth adhesive surface 215, thereby preventing the first adhesive surface 211 and the fifth adhesive surface 215 from separating and causing damage to the connecting portion 210. The first clamping portion 161 and the second clamping portion 162 can move towards each other or away from each other in the vertical direction. Specifically, when the handle 200 needs to be conveyed to the pressure-holding assembly 130, the first clamping portion 161 and the second clamping portion 162 will move towards each other in the vertical direction to clamp the first adhesive surface 211 and the fifth adhesive surface 215 respectively, so that the first adhesive surface 211 and the fifth adhesive surface 215 remain in a mating state. When the handle 200 reaches the upstream of the pressure holding assembly 130 to enter the pressure holding cavity, the first clamping part 161 and the second clamping part 162 will move in opposite directions in the vertical direction to separate from the first adhesive surface 211 and the fifth adhesive surface 215 respectively, so that the connecting part 210 enters the pressure holding cavity.

[0053] Furthermore, in some embodiments, see [reference] Figures 1 to 8 As shown, the handle pressure-holding mechanism 100 also includes a lifting member 170 and a movable member 180. The lifting member 170 is connected to the movable member 180, and the movable member 180 is connected to the clamping assemblies 160 on both sides of the conveyor belt 120. When the first clamping part 161 and the second clamping part 162 of the clamping assembly 160 clamp the connecting part 210 of the handle 200, the lifting member 170 and the movable member 180 will drive the first clamping part 161 and the second clamping part 162 to move so that the handle 200 is conveyed to the pressure-holding assembly 130.

[0054] Specifically, the lifting member 170 is connected to the movable member 180, and the movable member 180 is connected to the clamping assembly 160. When the clamping assembly 160 clamps the connecting part 210, the lifting member 170 drives the movable member 180 and the clamping assembly 160 to move vertically, causing the handle 200 and the clamping assembly 160 to move upward away from the conveyor belt 120, thereby preventing the handle 200 or the clamping assembly 160 from rubbing or colliding with the conveyor belt 120 during the transport of the handle 200, which could lead to damage to the handle 200. When the movable member 180 and the clamping assembly 160 rise to a certain height, the upward movement stops. The movable member 180 drives the clamping assembly 160 to move relative to the lifting member 170, changing the position of the first clamping part 161 and the second clamping part 162 relative to the conveyor belt 120 in the front-back direction, so that the handle 200 is transported to the pressure holding assembly 130.

[0055] Furthermore, in some embodiments, see [reference] Figures 1 to 8 As shown, the movable component 180 is rotatably connected to the lifting component 170. The movable component 180 drives the clamping assembly 160 to rotate relative to the lifting component 170 around an axis set in the vertical direction. Specifically, one end of the lifting component 170 is connected to a driving device (such as a motor or cylinder), and the other end is rotatably connected to the movable component 180. The lifting component 170 drives the movable component 180 and the clamping assembly 160 to move vertically through the driving device. After rising to a certain height, the movable component 180 drives the clamping assembly 160 to rotate, thereby changing the position of the handle 200 on the conveyor belt 120. Then, through the descending movement of the lifting component 170, the handle 200 is returned to the conveyor belt 120 for conveying into the pressure holding chamber. After the handle 200 is formed, the clamping mechanism keeps the connecting part 210 in a folded state, and the lifting part 170 and the moving part 180 transport the handle 200, which can prevent the handle 200 from delaminating and the folded part from separating before it is transported to the pressure holding assembly 130.

[0056] In another embodiment, the movable member 180 is slidably connected to the lifting member 170, and the movable member 180 drives the clamping assembly 160 to rotate relative to the lifting member 170 in the front-back direction. Specifically, one end of the lifting member 170 is connected to a driving device (e.g., a motor, cylinder), and the other end is connected to the movable member 180. A slide rail is provided along the front-back direction at the end of the lifting member 170 connected to the movable member 180, and the movable member 180 is connected in the slide rail. When the lifting member 170 drives the movable member 180 and the clamping assembly 160 to a certain height, the movable member 180 will drive the clamping assembly 160 to slide along the path of the slide rail, thereby conveying the handle 200 to the pressure holding assembly 130. Then, through the descending movement of the lifting member 170, the handle 200 is placed back on the conveyor belt 120 for conveying into the pressure holding chamber.

[0057] In some embodiments, see Figure 1 and Figure 8 As shown, the conveyor belt 120 is provided with a plurality of partitions 121, which are located on the side of the conveyor belt 120 away from the support platform 110 and protrude in an upward direction. The plurality of partitions 121 are spaced apart in the front-back direction, thereby giving the conveyor belt 120 a plurality of partitioned receiving grooves 122 for accommodating handles 200.

[0058] Specifically, the handle 200 is placed in the receiving groove 122 and folded sequentially to form the connecting part 210, conveying, and pressure holding. The partition 121 improves the safety and efficiency of the handle 200 conveying, reduces the possibility of damage to the handle 200, and simplifies subsequent sorting. However, since the connecting part 210 of the handle 200 enters the pressure holding cavity of the support plate 133 and the pressure holding plate 132, it comes into contact with either the support plate 133 or the pressure holding plate 132. Under the conveying of the conveyor belt 120, the connecting part 210 is subjected to friction, which affects the conveying speed of the handle 200 to some extent. The partition 121 separates the handles 200, preventing them from stacking or tangling during conveying, thus avoiding any impact on the discharge conveying of the handles 200.

[0059] In some embodiments, the divider 121 may be detachable, and the user may adjust the distance between adjacent dividers 121 or replace dividers 121 of different heights and shapes according to the size of the transport handle 200 to meet the transportation needs of handles 200 of different sizes.

[0060] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
