Description

Technical Field

[0001] The utility model relates to the technical field of sofa turning equipment, in particular to a stable turning equipment for sofa production. Background Art

[0002] When producing a sofa, after the sofa frame is made, the sofa frame needs to be turned over so that the bottom and surface of the sofa frame can be filled with fillers and the cover can be cut and sewn. However, the turning work of the existing sofa frame is mostly done by workers manually, which is time-consuming and labor-intensive and has low work efficiency. For this reason, we have introduced a turning device for sofa production.

[0003] According to a sofa production flipping device with a prior art patent announcement number of CN218664015U, when the above patent is used, the sofa frame body is placed on the bottom plate, and the sofa frame body is clamped and fixed by the clamping plate under the action of the electric telescopic rod. After it is clamped and fixed, the sofa frame body is driven to rotate by the clamping plate under the action of the brake motor to achieve the purpose of flipping the sofa frame. The operation is simple and it brings convenience to the subsequent processing of the sofa;

[0004] However, from a practical point of view, the above patent only relies on two groups of symmetrically distributed plywood to achieve the lateral clamping effect on the sofa frame when flipping the sofa frame. The actual locking effect on the sofa frame is general. Once the side surface of the sofa frame is polished smooth or sprayed with paint, the friction force of the plywood when in contact with the sofa frame is relatively small, so that the sofa frame is easily thrown off by the centrifugal force at a faster flipping speed, thereby affecting the processing effect.

[0008] The reinforcement mechanism includes two reinforcement plates symmetrically distributed on the side of the clamping plate away from the movable frame, and a U-shaped pressure rod is fixed on the side away from each other of the two reinforcement plates.

[0020] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0021] Reference Figure 1-4 As shown, a stable flipping device for sofa production includes a base 1 and a flipping mechanism for flipping a sofa frame;

[0022] The flip mechanism includes two hollow clamping plates 4 symmetrically arranged above the base 1, a movable frame 2 is arranged on one side of the clamping plate 4 away from the middle of the base 1, a lifting cylinder 3 is installed between both ends of the movable frame 2 and the base 1, a push cylinder 5 is installed between one side of the movable frame 2 and the clamping plate 4, and a driving motor 6 is installed on the other side of the movable frame 2, and the output shaft of the driving motor 6 rotates through the movable frame 2 and is fixedly connected to the push cylinder 5;

[0023] By setting the flipping mechanism, when the bottom of the sofa frame needs to be processed, the sofa frame to be processed can be placed between the two clamps 4 in advance, and then the push cylinder 5 is turned on, and the telescopic rod of the push cylinder 5 pushes the clamp 4 to the position against the edge of the sofa frame, so that the two clamps 4 can cooperate to achieve the effect of clamping the sofa frame, and then the lifting cylinder 3 is turned on to lift the sofa frame to provide enough flipping space for the flipping of the sofa frame, and finally the driving motor 6 is turned on, and the output shaft of the driving motor 6 can drive the pushing cylinder 5 and the clamp 4 as a whole to achieve the effect of flipping the sofa frame.

[0024] However, in practice, when the sofa frame is flipped, the above embodiment only relies on two groups of symmetrically distributed clamping plates 4 to achieve a lateral clamping effect on the sofa frame, and the actual locking effect on the sofa frame is general. Once the side surface of the sofa frame is polished smooth or sprayed with paint, the friction force of the clamping plates 4 when in contact with the sofa frame is relatively small, so that the sofa frame is easily thrown off by the centrifugal force at a faster flipping speed, thereby affecting the processing effect;

[0025] For this purpose, refer to Figure 1-3 As shown, it is worth noting that it also includes a reinforcing mechanism for improving the stability of the sofa frame when it is turned over;

[0026] The reinforcement mechanism includes two reinforcement plates 8 symmetrically distributed on the side of the clamping plate 4 away from the movable frame 2, and a U-shaped pressure rod 10 is fixed on the side away from the two reinforcement plates 8. The end of the pressure rod 10 penetrates into the clamping plate 4 and is fixed with a movable seat 11. A magnetic attraction component is arranged between the two movable seats 11. Two sets of transmission components are symmetrically arranged on the side of the clamping plate 4 facing the reinforcement plate 8.

[0027] By setting the reinforcement mechanism, when the sofa frame is flipped by using the flipping mechanism, the magnetic attraction component in the reinforcement mechanism attracts one of the movable seats 11 and causes the movable seat 11 to slide on the inner side of the clamping plate 4, and the other movable seat 11 can synchronously slide in the opposite direction under the action of the transmission component, thereby the two movable seats 11, the pressure rod 10 and the reinforcement plate 8 slide synchronously in opposite directions until the two reinforcement plates 8 quickly clamp the sofa frame longitudinally, which can further enhance the firmness of the sofa frame when flipping and reduce the possibility of the sofa frame being thrown off when flipping.

[0028] Further, refer to Figure 3 As shown, it is worth noting that the magnetic attraction component includes a fixing plate 12 transversely fixed between the inner walls of both sides of the clamping plate 4, an electromagnet 13 is installed on one surface of the fixing plate 12, and a magnet block 14 corresponding to the electromagnet 13 is fixed on one of the movable seats 11;

[0029] The transmission component includes two staggered tooth plates 15 and a transmission column 16 disposed between the two tooth plates 15 and rotatably connected to the outer wall of the clamping plate 4. A transmission gear 17 meshing with the tooth plates 15 is fastened and sleeved on the rod of the transmission column 16. A movable block 18 is fixedly connected between the two tooth plates 15 and the two movable seats 11, respectively. A sliding slot adapted to the movable block 18 is vertically opened on the outer wall of the clamping plate 4.

[0030] When the sofa frame is flipped by using the flipping mechanism, the electromagnet 13 is turned on. The electromagnet 13 can effectively form an attraction for the magnet block 14 and one of the movable seats 11, causing the movable seat 11 to slide down under the force on the inner side of the splint 4, and act on the corresponding fixed tooth plate 15 to slide down on the outer side of the splint 4. In this way, the tooth plate 15 is meshed with the transmission gear 17, so that the transmission gear 17 can be meshed with another tooth plate 15 during the rotation process, and the other tooth plate 15 can carry the corresponding fixed movable seat 11 to slide up, so that the two movable seats 11 slide in opposite directions, and synchronously make the two reinforcement plates 8 slide in the same direction to clamp the sofa frame.

[0031] Further, refer to Figure 2 As shown, it is worth noting that a compression spring 20 is sleeved on the rod body of one of the pressure rods 10, and a circular ring-shaped compression plate 19 is fixed to one end of the compression spring 20. The compression plate 19 is tightly sleeved on the rod body of the pressure rod 10, and the other end of the compression spring 20 is fixedly connected to the outer wall of the clamping plate 4;

[0032] When the two pressure rods 10 slide towards each other, one of the pressure rods 10 can carry the pressure plate 19 close to the clamping plate 4 during the process of contracting toward the inner side of the clamping plate 4, causing the pressure plate 19 to compress the clamping spring 20 and deform. In this way, when the electromagnet 13 is turned off and the attraction of the electromagnet 13 to the magnet block 14 and one of the movable seats 11 is released, the pressure plate 19 can carry one of the pressure rods 10 to reset under the action of the elastic force of the clamping spring 20. Similarly, the other pressure rod 10 can be reset under the action of the transmission component, so as to facilitate secondary use.

[0033] Further, refer to Figure 4 As shown, it is worth noting that anti-skid pads 9 can be detachably provided on the corresponding sides of the two reinforcement plates 8;

[0034] By providing the anti-slip pad 9, when the reinforcing plate 8 contacts the surface of the sofa frame, the friction between the reinforcing plate 8 and the sofa frame can be enhanced, thereby improving the fixation of the sofa frame.

[0035] Further, refer to Figure 4As shown, it is worth noting that an insert strip 21 is fixed to the top surface of the anti-slip pad 9, a slot adapted to the insert strip 21 is provided on the side of the reinforcement plate 8, a locking screw 7 is provided on the top of the reinforcement plate 8, a fixing hole adapted to the locking screw 7 is provided on the insert strip 21, and the locking screw 7 is threaded into the slot and extends into the fixing hole;

[0036] When the anti-skid pad 9 is seriously worn out after a long time, it is only necessary to simply turn the knob to lock the screw 7 so that the locking screw 7 can be withdrawn from the fixing hole under the threaded structure, thereby releasing the fixation of the insert 21 in the slot. In this way, the anti-skid pad 9 can be easily slid and the insert 21 can be withdrawn from the slot, so that the worn anti-skid pad 9 can be easily replaced.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
