Description

Technical Field

[0001] The utility model relates to the technical field of furniture parts processing, in particular to a temperature-controlled cutting device for a sofa sponge pad. Background Art

[0002] Sofa sponge pad is a kind of soft filling material, which is often used in the processing and manufacturing of furniture such as sofas, chair cushions or mattresses to increase the comfort and sitting feeling of the furniture. Usually, the sofa sponge pad is made of materials such as polyurethane, polyester and latex to make it have excellent elasticity and durability.

[0003] Therefore, using a sponge pad on the sofa can improve the softness and comfort of the sofa, so as to better support the body and make the user more comfortable when using the sofa. At the same time, the sponge pad can also play a role in anti-slip and protecting the sofa, extending the service life of the sofa.

[0004] Furthermore, the design of sofa sponge pads also needs to take into account whether it meets ergonomic requirements, and the seat cushions usually wear out faster than the back cushions because the thighs and buttocks of a person will cause greater pressure and wear on the seat cushions. Therefore, many sofa sponge pads are designed to have one more piece than the main body to reduce the wear of the bottom of the sofa and improve the softness and comfort of the sofa. Therefore, manufacturers often need to carry out separate processing technology based on the structural characteristics of sofa sponge pads.

[0005] Based on this, Chinese patent CN110640810B discloses an automatic sponge cutting machine, which includes a fixing device for fixing sponges, a moving device for moving sponges and a cutting device, wherein the cutting device includes a first cutting piece, a second cutting piece matched with the first cutting piece, a third cutting piece matched with the first cutting piece, a first adjustment mechanism for adjusting the height difference between the first cutting piece and the second cutting piece, a second adjustment mechanism for adjusting the third cutting piece and the first cutting piece, and a switching mechanism for switching the positions of the first cutting piece and the third cutting piece, wherein the second cutting piece and the third cutting piece are respectively arranged on both sides of the first cutting piece, and the fixing device includes a placing plate, a pressing roller symmetrically arranged above the placing plate, a pressing roller fixing mechanism for fixing the pressing roller, and an adjusting mechanism for adjusting the height of the pressing roller. Thus, the automatic sponge cutting machine disclosed in the patent can press down the sponge during the cutting process by setting a pressing roller to prevent the upper layer of the sponge from being offset under the action of shear force, thereby ensuring the flatness of the sponge cut.

[0006] However, the sponge cutting machine disclosed above still has the technical problem of inaccurate cutting dimensions. Specifically, the existing patent mainly uses a cutting knife perpendicular to the cutting plane of the sponge to achieve the cutting of the sponge. However, since the sponge is a soft material, the characteristics of this material and the mechanical action of the cutting knife during the punching process may cause the edge of the sponge to have slight undulations or wavy shapes, making the edge of the sponge uneven after cutting; thus, it will affect the appearance and use of the sponge pad. In addition, the softness and volatility of the sponge may cause it to deform or twist during the cutting process, thereby affecting the accuracy of the cutting size. Although the existing patent has improved this technical problem by setting a pressure roller to press the sponge, it is still difficult to completely eliminate the error; moreover, the sponge that has been pressed by a huge force will also be mechanically damaged, which may cause irreversible deformation.

[0030] Specifically, when the temperature-controlled cutting device for a sofa sponge pad of the utility model is in the working process, the semi-finished sponge product to be cut is securely limited and placed on the rotating table 2, and the rotating power mechanism 3 drives the rotating table 2 to drive the semi-finished sponge product to rotate to a preset angle; the two horizontal action mechanisms 4 simultaneously drive the two vertical action mechanisms 5 to drive the temperature-controlled cutting mechanism 6 to move from the initial position to the first cutting position; thereafter, the temperature-controlled cutting mechanism 6 is powered on and heated, and after the temperature is heated to a preset temperature, the two vertical action mechanisms 5 are simultaneously actuated to drive the temperature-controlled cutting mechanism 6 to move downward to the first cutting position to complete the cutting of the semi-finished sponge product; after the cutting is completed, the two vertical action mechanisms 5 drive the temperature-controlled cutting mechanism 6 to reset to a preset height, and the two horizontal action mechanisms 4 then drive the two vertical action mechanisms 5 to the next position according to a preset action trajectory; the temperature-controlled cutting mechanism 6 repeats the cutting and resetting actions.

In the technical solution of the temperature control cutting device for sofa sponge pads of the utility model, after the temperature control cutting mechanism 6 controls the temperature rise to reach a sufficient temperature, when the cutting part contacts the sponge, the sponge material can be quickly cut off to form a precise cutting edge shape.
