Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, and more specifically, to a male mold quick-release clamp. Background Art

[0002] This section is intended to provide background or context for the embodiments of the present invention set forth in the claims. The descriptions herein may include concepts that may be explored, but not necessarily concepts that have been previously thought of or explored. Therefore, unless otherwise noted herein, the content described in this section is not prior art with respect to the specification and claims of the present invention, and is not admitted to be prior art by inclusion in this section.

[0003] In packaging automation production lines and equipment, when it comes to the process of forming paper boxes, the male and female molds need to cooperate to form the paper. The male molds required for different specifications of paper boxes will be different, so when changing the specifications of the produced paper boxes, the corresponding male molds need to be replaced.

[0004] There are two types of male molds available on the market: one is installed with bolts or other types of fasteners. When replacing, a wrench is needed to remove the fasteners, and then the fasteners are tightened after replacing the new forming head. This method has cumbersome steps for changing molds and takes a long time to change molds. Another method is to use a cylinder-type linear drive mechanism to directly drive a pressure plate to press the forming head on the mounting seat. When changing molds, the cylinder is lifted and the forming head is removed. After installing the new forming head, the cylinder is lowered and the new forming head is re-tightened. This method requires a larger cylinder diameter to withstand the impact force on the forming head during the forming process, which will result in a larger size of the changing fixture.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0040] To solve relevant technical problems, such as Figures 1 to 5 As shown, the embodiment of the utility model provides a male mold quick-release clamp, comprising:

[0041] A frame body 2, on which a first clamping portion 3 is disposed, and on which a supporting surface 31 for supporting the male mold 1 is disposed;

[0042] The second clamping part 4 is disposed above the supporting surface 31. The second clamping part 4 includes a crank slider mechanism 42 and a linear drive mechanism 40. The crank slider mechanism 42 includes a slider 422, a crank 420 and a connecting rod 421.

[0043] The slider 422 is configured to be able to slide in the vertical direction above the support surface 31;

[0044] The first end of the crank 420 is hinged to the frame 2, the first end of the connecting rod 421 is hinged to the slider 422, the second end of the crank 420, the second end of the connecting rod 421, and the output end of the linear drive mechanism 40 are hinged, and the output end of the linear drive mechanism 40 is configured to have the freedom to move with the slider 422, so that the linear drive mechanism 40 can drive the slider 422 to slide in the vertical direction.

[0045] In this embodiment, the frame 2 is used as a fixed structure, and a first clamping portion 3 is provided at the lower end of the frame 2. The upper end of the male mold 1 can be installed in the frame 2 and located on the support surface 31 of the first clamping portion 3. In this embodiment, the support surface 31 of the first clamping portion 3 can be a horizontal plane, and the upper end of the male mold 1 has a plate-like structure to be clamped and fixed, and the plate-like structure can be placed on the support surface 31. Under the supporting effect of the support surface 31 on the male mold 1, in order to achieve the fixation of the male mold 1, it is necessary to apply a certain pressure to the male mold 1 from the upper side of the male mold 1, so as to press and fix the male mold 1 on the support surface 31. Therefore, in this embodiment, a second clamping portion 4 is also provided, and the second clamping portion 4 mainly includes a crank slider mechanism 42 and a linear drive mechanism 40, and the crank slider mechanism 42 and the linear drive mechanism 40 can be located above the support surface 31.

[0046] The linear drive mechanism 40 is used to output linear motion, and the linear drive mechanism 40 can be set as a linear cylinder or a linear motor. The crank slider mechanism 42 is used to apply downward pressure to the male mold 1 under the action of the linear drive mechanism 40. In this embodiment, the crank slider mechanism 42 can change the direction of the force output by the linear drive mechanism 40, so that the vertical upward impact force generated by the male mold 1 during use will not directly act on the linear drive mechanism 40.

[0047] Specifically, the crank slider mechanism 42 in this embodiment includes a slider 422, a crank 420 and a connecting rod 421. The slider 422 can be set on the frame 2 and can slide linearly in the vertical direction. After the first end of the crank 420 is hinged to the frame 2, the first end of the connecting rod 421 is hinged to the slider 422, and the second end of the crank 420, the second end of the connecting rod 421, and the output end of the linear drive mechanism 40 are hinged, the outward extending linear motion output by the linear drive mechanism 40 can act on the second end of the crank 420 and the connecting rod 421, so that the crank 420 and the connecting rod 421 both rotate and increase the angle between the crank 420 and the connecting rod 421, so that the connecting rod 421 pushes the slider 422 to move downward and press it against the upper end of the male mold 1. During disassembly, the linear drive mechanism 40 is controlled to output an inwardly retracting linear motion, thereby pulling the second end of the crank 420 and the connecting rod 421, causing the crank 420 and the connecting rod 421 to rotate in the opposite direction and reducing the angle between the crank 420 and the connecting rod 421, so that the connecting rod 421 pulls the slider 422 to rise and detach from the male mold 1, and then the male mold 1 can be removed from the supporting surface 31.

[0048] According to the movement process of the crank slider mechanism 42, it can be known that after the crank 420 and the second end of the connecting rod 421 are hinged, the hinge point will rotate when subjected to thrust and will also produce a certain displacement. The displacement can be decomposed into the vertical direction and the horizontal direction. Therefore, the linear drive mechanism 40 needs to have the freedom to cooperate with the movement of the hinge point when outputting linear motion, that is, the freedom to follow the slider 422. In one embodiment, the driving end of the linear drive mechanism 40 is fixed, and a structure that allows the hinge point to produce vertical movement is configured at the output end, such as a slide groove, a slide rail, etc., and the horizontal movement of the hinge point is provided by the horizontal linear motion output by the linear drive mechanism 40. In another embodiment, the linear drive mechanism 40 is non-fixed, and is hinged to the frame 2 so that the linear drive mechanism 40 can produce a certain amount of swing, thereby having the freedom to cooperate with the movement of the hinge point, that is, the freedom to follow the slider 422.

[0049] The present embodiment achieves the purpose of installing the male mold 1 on the supporting surface 31 during mold change, and the linear drive mechanism 40 drives the slider 422 in the crank slider mechanism 42 to move downward and press on the male mold 1 to complete the mold change and installation of the male mold 1. Under the action of the crank 420 and the connecting rod 421, the impact force exerted on the male mold 1 will not directly act on the linear drive mechanism 40, thereby achieving the purpose of making the mold change operation of the male mold 1 simple and convenient, reducing the impact force that the linear drive mechanism 40 needs to withstand, and relatively reducing the size of the linear drive mechanism 40. This solves the problem that the mold change operation of the male mold 1 installed by fasteners in the related art is cumbersome, and the male mold 1 directly driven by the drive mechanism will be subjected to a large impact force when in use, resulting in a large size requirement for the drive mechanism.

[0050] In order to balance the force of the male mold 1 and improve the stability of the male mold 1 after installation, Figure 1 and Figure 4 As shown, in this embodiment, the first clamping parts 3 are arranged on both sides of the frame 2, the crank slider mechanism 42 is arranged in two groups and respectively located on both sides of the frame 2, and the linear drive mechanism 40 corresponds to the crank slider mechanism 42.

[0051] Specifically, in this embodiment, the upper end of the male mold 1 is mounted on the first clamping parts 3 on both sides of the frame 2, and the two sides of the male mold 1 are supported by the support surfaces 31 on the first clamping parts 3 on both sides. The sliders 422 in the two sets of crank slider mechanisms 42 correspond to the support surfaces 31 on both sides, respectively. Through the movement of the two sets of crank slider mechanisms 42, the sliders 422 on both sides can be pressed against the two sides of the male mold 1, respectively, so that the force of the male mold 1 is balanced and the stability of the male mold 1 after installation is improved. Since the crank slider mechanism 42 is set as two groups, the linear drive mechanism 40 can be synchronously set as two groups, or the linear drive mechanism 40 can output linear motion in two directions at the same time, thereby driving the crank slider mechanisms 42 on both sides to move.

[0052] like Figure 2 and Figure 3 As shown, in the process of pressing the male mold 1 by the crank slider mechanism 42, the angle between the crank 420 and the connecting rod 421 gradually increases. In order to further reduce the impact force from the male mold 1 borne by the linear drive mechanism 40, the angle between the crank 420 and the connecting rod 421 should be 180°. At this time, the crank 420, the connecting rod 421 and the slider 422 are collinear in the vertical direction. The upward impact force exerted by the male mold 1 will be transmitted to the frame 2 along the collinear slider 422, the connecting rod 421 and the crank 420, so that the linear drive mechanism 40 is almost not affected by the impact force from the male mold 1.

[0053] Specifically, Figure 1 and Figure 2 As shown, in this embodiment, the hinge point of the frame 2 is located directly above the hinge point of the connecting rod 421 and the slider 422, so that when the slider 422 presses and clamps the male mold 1 on the support, the hinge point of the crank 420 and the frame 2, the hinge point of the crank 420 and the connecting rod 421, and the hinge point of the connecting rod 421 and the slider 422 are collinear in the vertical direction, so that the crank 420 and the connecting rod 421 are in a self-locking state.

[0054] In order to make the upper end of the male mold 1 bear force uniformly, the second clamping portion 4 in this embodiment further includes a pressing plate 6, which is located above the supporting surface 31, and the two sides of the pressing plate 6 are fixedly connected to the corresponding sliders 422. In this embodiment, the pressing plate 6 is generally a plate-shaped structure, and after the two sides of the pressing plate 6 are fixedly connected to the sliders 422, the linear motion of the sliders 422 will drive the pressing plate 6 to move linearly, so that the pressing plate 6 can be pressed tightly against the upper end of the male mold 1. Since the area of ​​the pressing plate 6 is relatively large, the force on the male mold 1 can be more uniform, and the impact force applied by the male mold 1 can also act evenly on the pressing plate 6.

[0055] In one embodiment of frame 2, as Figure 2 As shown, the frame 2 includes a horizontal plate 20 and a vertical plate 21. The vertical plates 21 are arranged on both sides of the horizontal plate 20. The first clamping portion 3 is a support plate 30 arranged at the lower end of the vertical plate 21, and the upper surface of the support plate 30 serves as a support surface 31. A slide rail is vertically arranged on the vertical plate 21, and the slider 422 is slidably arranged on the slide rail.

[0056] In this embodiment, the horizontal plate 20 and the vertical plates 21 on both sides constitute a door-shaped frame 2 structure, the support plate 30 is fixed to the lower end of the vertical plate 21 and extends in the horizontal direction, and there is a certain distance between the support plates 30 on both sides, so as to facilitate the insertion of the upper end of the male mold 1. On this basis, in order to facilitate the positioning of the male mold 1 before pressing, in this embodiment, a male mold 1 positioning pin is provided on the support plate 30, and the male mold 1 positioning pin can be inserted into the upper end of the male mold 1, so as to locate the position of the male mold 1 on the support plate 30.

[0057] In order to enable the linear drive mechanism 40 to have the freedom to move with the slider 422, in this embodiment, the driving end of the linear drive mechanism 40 is fixed to the frame 2, and a structure is additionally configured at the output end to allow the hinge point of the crank 420 and the connecting rod 421 to produce vertical movement.

[0058] Specifically, in this embodiment, if Figure 1 and Figure 2 As shown, the output end of the linear drive mechanism 40 includes a connecting seat 400, a wheel groove 401 is opened on the connecting seat 400 in the vertical direction, a pulley 402 is arranged in the wheel groove 401, the pulley 402 can slide in the wheel groove 401, and the second end of the crank 420, the second end of the connecting rod 421 and the pulley 402 are hinged.

[0059] In this embodiment, after the driving end of the linear drive mechanism 40 is fixedly connected to the frame 2, the output end can drive the connecting seat 400 to produce linear displacement in the horizontal direction. During the linear displacement, the vertical displacement generated by the hinge point of the crank 420 and the connecting rod 421 is provided by the pulley 402 and the wheel groove 401. Specifically, when the output end of the linear drive mechanism 40 drives the connecting seat 400 to extend outward, the pulley 402 slides from the upper end to the lower end of the wheel groove 401, and at the same time, the crank 420 and the connecting rod 421 rotate to increase the angle between the two, and push the slider 422 to slide downward; when the output end of the linear drive mechanism 40 drives the connecting seat 400 to retract inward, the pulley 402 slides from the lower end to the upper end of the wheel groove 401, and at the same time, the crank 420 and the connecting rod 421 rotate in the opposite direction to reduce the angle between the two, and drive the slider 422 to slide upward.

[0060] In an embodiment of the connecting seat 400, wheel grooves 401 are provided on both side walls of the connecting seat 400, and two pulleys 402 are provided and are respectively located in the wheel grooves 401 on both sides;

[0061] The second end of the crank 420 and the second end of the connecting rod 421 are hinged via a rotating shaft, and both ends of the rotating shaft are hinged to the corresponding pulleys 402 respectively.

[0062] Specifically, it should be noted that the side walls on both sides of the connection seat 400 can be arranged with a wheel groove 401 and a pulley 402, so that the second ends of the crank 420 and the connecting rod 421 are subjected to balanced forces. The connection seat 400 can use the side walls on both sides to limit the second ends of the crank 420 and the connecting rod 421, providing movement stability.

[0063] When the driving end of the linear drive mechanism 40 is fixedly connected to the frame 2, the output end of the linear drive mechanism 40 only pushes the connecting seat 400 to perform linear reciprocating motion in the horizontal direction. Therefore, in order to improve the accuracy of the linear reciprocating motion, Figures 1 to 3 As shown, the male mold 1 quick-release clamp in this embodiment also includes a guide mechanism 41, which includes a fixed portion 410 and a guide portion 411. The guide portion 411 can move linearly in a horizontal direction relative to the fixed portion 410. The fixed portion 410 is fixed on the frame 2, and the end of the guide portion 411 is fixedly connected to the connecting seat 400.

[0064] In this embodiment, the guide mechanism 41 provides guidance for the horizontal linear motion of the connection seat 400. After the fixing portion 410 in the guide mechanism 41 is fixedly connected to the frame 2, the guide portion 411 installed in the fixing portion 410 can move with the connection seat 400. The guide portion 411 cooperates with the fixing portion 410 to make the linear reciprocating motion of the connection seat 400 more accurate. In this embodiment, the linear drive mechanism 40 can be fixed on the frame 2 or on the fixing portion 410.

[0065] Furthermore, in one embodiment of the fixing portion 410 and the guiding portion 411, the fixing portion 410 includes a guide seat in which a linear bearing is disposed, and the guiding portion 411 includes a guide shaft which is sleeved in the linear bearing, and an end portion of the guide shaft is fixedly connected to the connecting seat 400.

[0066] In another embodiment of the fixing portion 410 and the guiding portion 411 , the fixing portion 410 includes a guiding rail, and the guiding portion 411 includes a guiding rail slider 422 , the guiding rail slider 422 is slidably disposed on the guiding rail, and the end of the guiding rail slider 422 is fixedly connected to the connecting seat 400 .

[0067] In order to allow the linear drive mechanism 40 to have the freedom to follow the slider 422 , the linear drive mechanism 40 in this embodiment is non-fixed and can generate a certain amount of swing by being hinged to the frame 2 .

[0068] Specifically, Figures 4 to 6 As shown, the male mold 1 quick-release clamp in this embodiment further includes a connecting member 403, a first end of the connecting member 403 is fixedly connected to the output end of the linear drive mechanism 40, and a second end of the connecting member 403 is hinged to the second end of the crank 420 and the second end of the connecting rod 421;

[0069] The driving end of the linear driving mechanism 40 is hinged to the frame 2 .

[0070] Specifically, in this embodiment, since the driving end of the linear drive mechanism 40 is hinged to the frame 2, and the output end is hinged to the second end of the crank 420 and the connecting rod 421 through the connecting member 403, the linear drive mechanism 40 is in a state where it can swing up and down. When the output end of the linear drive mechanism 40 drives the connecting member 403 to extend, the linear drive mechanism 40 swings downward synchronously. During this process, the crank 420 and the connecting rod 421 rotate to increase the angle between the two, and push the slider 422 to slide downward (such as Figure 6 When the output end of the linear drive mechanism 40 drives the connecting member 403 to retract, the linear drive mechanism 40 swings upward synchronously. During this process, the crank 420 and the connecting rod 421 rotate in opposite directions to reduce the angle between the two, and drive the slider 422 to move upward (as shown in FIG. Figure 4 and Figure 5 In this embodiment, the foot seat 7 can be fixed on the frame 2, and the driving end of the linear drive mechanism 40 can be hinged to the foot seat 7.

[0071] The above description is only the preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement, etc. made shall be included in the protection scope of the utility model.
