Description

Technical Field

[0001] This utility model relates to the technical field of foam clamping devices, and in particular to a stable clamping device for large-scale foam production. Background Technology

[0002] After foaming, curing, and molding, polystyrene beads form a cuboid structure with a large volume. In subsequent cutting, they need to be slit first so that they can be placed on the cutting table. Currently, the cutting of foam is usually completed during intermediate transmission by clamping the top of the foam to achieve the slit operation. However, in the existing clamping process, the clamping structure mostly adopts a scissor-type clamping method. During the clamping process, the contact area is small, and the structure of the clamps is also prone to surface damage, affecting subsequent production. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a large-scale foam production stable clamping device in response to the above-mentioned technical deficiencies. By increasing the contact area through clamping plates and adjusting the position of the push frame drive combination rod, the clamping operation can be realized, which can effectively improve the reliability after clamping and reduce damage to the surface of the foam.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is a large-scale foam production stabilizing clamping device, comprising: a crossbeam, side plates, a combined rod, and a clamping plate; side plates are respectively installed on both sides of the crossbeam, and a first hydraulic cylinder is provided in the middle, with an assembly plate on the push rod of the first hydraulic cylinder; a vertical channel is provided on the inner side of the side plates, and a push frame connected to the assembly plate is provided in the vertical channel; two ends of the combined rod are respectively connected to the push frame and the side plate as rotating shafts, and the other end is connected to the clamping plate. The combined rod is driven to move downward by the push frame to complete the clamping operation.

[0005] Preferably, the crossbeam is symmetrically provided with sliding rails and located between two sliding rails, and an adjusting rod is provided on the crossbeam; the side plate is symmetrically provided with sliders connected to the sliding rails, and the side plate is threadedly connected to the adjusting rod.

[0006] Preferably, the assembly plate has a groove in the middle that connects to the first hydraulic cylinder.

[0007] Preferably, the combined rod includes a swing rod and a middle rod; one end of the swing rod is connected to the side plate by a pivot, and the other end is connected to the clamping plate by a pivot; one end of the middle rod is connected to the push frame by a pivot, and the other end is provided with a sleeve connected to the swing rod.

[0008] Preferably, the intermediate rod includes an upper base and a lower base; the upper base is provided with a plurality of sliding rods that pass through the lower base, and a force-bearing spring is provided between the upper base and the lower base.

[0009] Preferably, the surface of the clamping plate is provided with a rubber layer.

[0010] Preferably, the rubber layer is provided with a plurality of pressure strips evenly distributed on it.

[0011] Preferably, an auxiliary pull rope connected to the side plate is provided above the clamping plate.

[0012] Preferably, a counterweight is provided below the clamping plate.

[0013] Preferably, the two ends of the crossbeam are provided with positioning slides.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. By driving the combined rod displacement through the push frame, the clamping plate moves closer to the foam to complete the clamping. Compared with the traditional scissor clamping structure, it can ensure full contact between the clamping plate and the foam, increase the contact area, improve clamping stability, and reduce damage to the surface of the foam.

[0017] 3. The rubber layer on the clamping plate can increase the friction after contact with the foam. At the same time, the design of the pressure strip can be pressed into the surface of the foam to deform without causing damage, thereby increasing the clamping force on the foam and further enhancing the firmness after clamping.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0028] Specific implementation method one: Combining Figures 1-8 As shown, a large-scale foam production stabilizing clamping device includes: a crossbeam 1, side plates 2, a combination rod 3, and a clamping plate 4; side plates 2 are respectively installed on both sides of the crossbeam 1, and the side plates are welded to the crossbeam; a first hydraulic cylinder 101 is provided in the middle of the crossbeam, and an assembly plate 102 is provided on the push rod of the first hydraulic cylinder 101; a vertical channel 201 is provided on the inner side of the side plate 2, and a push frame 202 connected to the assembly plate 102 is provided in the vertical channel 201; two ends of the combination rod 3 are respectively connected to the push frame 202 and the side plate 2 by rotating shafts, and the other end is connected to the clamping plate 4. The combination rod 3 is driven to move downward by the push frame 202 to complete the clamping operation;

[0029] After the foam body is moved to the crossbeam 1 by the conveyor belt, the pusher 202 is driven by the first hydraulic cylinder 101 to move downward along the vertical channel 201, so that the combination rod 3 drives the clamping plate 4 to complete the clamping of the foam board. Relying on the widened design of the clamping plate 4 itself and the pushing method of the combination rod 3, the contact area with the surface of the foam body can be effectively increased, the stability after clamping can be improved, and damage to the surface of the foam body can be avoided.

[0030] Preferred embodiments, in combination Figure 3As shown, symmetrical sliding rails 103 are provided on the crossbeam 1. The internal cross section of the sliding rails 103 is T-shaped and located between two sliding rails 103. An adjusting rod 104 is provided on the crossbeam 1. The two ends of the adjusting rod 104 are connected to the crossbeam 1 by rotating shafts and the surface is machined with external threads. Slider blocks 203 connected to the sliding rails 103 are symmetrically provided above the side plate 2. The side plate 2 is threadedly connected to the adjusting rod 104. The position of the side plate 2 can be adjusted by rotating the adjusting rod 104. The adjusting rod 104 can be rotated manually or a control motor can be installed on the crossbeam 1 to drive it electrically, making operation and control more convenient.

[0031] Preferred embodiments, in combination Figure 2 and Figure 8 As shown, the assembly plate 102 has a groove 105 in the middle that is connected to the first hydraulic cylinder 101, and the middle part is broken into left and right parts. The push rod of the first hydraulic cylinder 101 is provided with a guide slide that is connected to the groove 105. The two form a sliding connection, so that during the adjustment of the side plate 2, the assembly plate 102 can be displaced along the guide slide, and the first hydraulic cylinder 101 pushes the assembly plate 102 downward. When the side plate 2 is directly fixedly connected to the crossbeam 1, the assembly plate 102 can directly adopt a complete horizontal plate structure and be fixedly connected to the push rod of the first hydraulic cylinder 101.

[0032] Preferred embodiments, in combination Figure 2 As shown, the combination rod 3 includes a swing rod 301 and a middle rod 302; one end of the swing rod 301 is connected to the side plate 2 by a pivot, and the other end is connected to the clamping plate 4 by a pivot; one end of the middle rod 302 is connected to the push frame 202 by a pivot, and the other end is provided with a sleeve 303 connected to the swing rod 301. The sleeve 303 and the swing rod 301 form a sliding connection. The push frame 202 moves downward, and the middle rod 302 drives the swing rod 301 to swing, so that the clamping plate 4 moves closer to the foam body and completes the clamping action.

[0033] In a preferred embodiment, to prevent excessive clamping force, combined with Figure 4 As shown, the intermediate rod 302 is designed to include an upper base 304 and a lower base 305. The upper base 304 is provided with multiple sliding rods 306 that pass through the lower base 305, and a force spring 307 is provided between the upper base 304 and the lower base 305. During the clamping process, after the rated force is exceeded, the force spring 307 is triggered to compress, thereby achieving safety protection.

[0034] Preferred embodiments, in combination Figure 4As shown, depending on the specifications of the foam, by precisely controlling the displacement distance of the pusher 202, the installation of the force spring 307 is not required. Instead, the upper base 304 and the lower base 305 are welded together by the slide rod 306 to form an integrated structure.

[0035] Preferred embodiments, in combination Figure 6 As shown, the surface of the clamping plate 4 is provided with a rubber layer 401. The rubber layer 401 is made of natural rubber, which can increase the friction after contact with the foam and improve the stability of clamping.

[0036] Preferred embodiments, in combination Figure 6 As shown, multiple pressure strips 402 are evenly provided on the rubber layer 401. The pressure strip 402 has a triangular cross-sectional shape and the top is rounded. During the clamping process, it can be pressed into the foam to form a snap-fit, which further improves the reliability after clamping.

[0037] Preferred embodiments, in combination Figure 1 , Figure 2 and Figure 5 As shown, an auxiliary pull rope 403 connected to the side plate 2 is provided above the clamping plate 4. The auxiliary pull rope 403 has a certain elasticity, and the auxiliary clamping plate 4 is kept in a relatively vertical state to avoid affecting the clamping. The core of the auxiliary pull rope 403 is made of natural rubber or synthetic rubber and is covered with wear-resistant fabric (such as nylon or polyester fiber).

[0038] Preferred embodiments, in combination Figure 2 and Figure 5 As shown, a counterweight 404 is provided below the clamping plate 4, which can increase the gravity below the clamping plate 4. Together with the elasticity of the auxiliary pull rope 403, it keeps the clamping plate 4 in a slightly inward tilted state, which is convenient for clamping. In the case of small displacement, the elasticity of the auxiliary pull rope 403 will not pull the clamping plate 4 to rotate excessively, keeping it within a certain angle. Of course, in order to improve the stability of the clamping plate 4, a second hydraulic cylinder can also be set at the position of the auxiliary pull rope 403. The other end of the second hydraulic cylinder is connected to the rotating shaft of the side plate 2. The second hydraulic cylinder extends and retracts itself as it follows the position change of the swing rod 301, maintaining the position of the clamping plate 4 and providing a stable clamping function after clamping, replacing the design of the auxiliary pull rope 403 and the counterweight 404.

[0039] Preferred embodiments, in combination Figure 7 As shown, the two ends of the crossbeam 1 are provided with positioning slides 106. By arranging the longitudinal support, the longitudinal support has longitudinal displacement channels with a dovetail shape on both sides, which cooperate with the positioning slides 106 to form a sliding connection. A winch is set at the top of the longitudinal support. The steel rope of the winch is connected to the top of the crossbeam 1. The overall height of the device is raised and lowered by winding. After the foam is cut, the foam of the clamping part can be moved downward and placed on the conveyor belt for transmission.

[0040] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
