Description

Technical Field

[0001] The utility model belongs to the technical field of sponge processing, in particular to a sponge inner core processing device for a cushion. Background Art

[0002] The design of cutting corners on the sponge core of sofa cushions is becoming more and more popular in modern furniture. This design not only focuses on practicality and comfort, but also takes aesthetics into consideration. The design of cutting corners on sofa sponges reflects the modern and simple style, which conforms to the current popular home design concept. This design reduces excessive decorative elements and creates a clean and neat visual effect through simple lines and shapes. In addition, the design of cutting corners can also increase the three-dimensional sense of the sofa, and fully considers ergonomics and usage functions. The design of cutting corners can provide better support and comfort, and can also adapt to different sitting postures and body shapes. Such a design not only meets practicality, but also improves aesthetics.

[0003] The Chinese patent document with the authorization announcement number CN212554078U discloses a sponge beveling machine, which includes a beveling mechanism, a conveying platform and a control console, wherein the beveling mechanism is located on one side of the conveying platform, and includes a base, an adjusting device for adjusting the height and angle, and a beveling device for beveling the sponge corner, wherein the adjusting device is rotatably mounted on the base, and the beveling device is rotatably mounted above the adjusting device, and the conveying platform, the adjusting device and the cutting device are all electrically connected to the control console.

[0004] When the above-mentioned patented solution is in use, the sponge placed on the conveyor belt or the mobile table often needs to be manually supported and positioned to improve the aesthetics and accuracy of the cutting, which undoubtedly increases the probability of contact between the manual labor and the cutting tool, posing certain safety hazards; in addition, the sponge has great compressibility and is not easy to fix. At the same time, the sponge cutting process is very fast and the cutting amount is often large, and the processed sponge needs to be frequently replaced and adjusted in position. Therefore, these factors restrict the sponge cutting efficiency. Utility Model Content

[0005] In order to overcome the technical problems in the prior art that the sponge needs to be manually supported and positioned during bevel cutting, and the bevel cutting process of the sponge needs to be frequently replaced and adjusted, and the complex mechanical fixing method will reduce the working efficiency; one purpose of the utility model is to provide a sponge core processing equipment for a seat cushion, by connecting a needle plate with a horizontal sliding connection on a lifting frame arranged for longitudinal sliding, the two needle plates slide horizontally towards each other to fix the sponge, and the lifting frame slides downward to store it to provide enough space for the movement of the sponge, and a hand wheel connected to the needle plate and the lifting frame is provided at the same time, so as to simplify the working steps of the operator.

[0006] To achieve the above object, the present utility model adopts the following technical solutions: A processing device for the sponge inner core of a cushion, comprising a chassis, on one side of which an inclined cutting machine is provided; a mounting frame which is slidably connected to the upper end of the chassis; two fixing parts which are symmetrically arranged in the mounting frame; and a plurality of splicing plates which are respectively detachably connected in the mounting frame, and each splicing plate is located between the two fixing parts and fills the gap between the two fixing parts: wherein, the fixing part includes a substrate detachably connected in the mounting frame, a lifting frame longitudinally slidably connected to the substrate, and a needle plate horizontally slidably connected to the lifting frame; a handwheel is rotatably connected to the mounting frame and is in transmission connection with the lifting frame and the needle plate.

[0008] The position of the fixing part can be adjusted, and at the same time, the splicing plate fills the gap between the two fixing parts, so that sponges of different sizes can be compatible.

[0009] Further, the fixing part includes a transmission rod rotatably connected to the lifting frame and in transmission connection with the needle plate, a transmission gear rotatably connected to the substrate and in transmission connection with the transmission rod, and a linkage plate slidably connected to the substrate and in transmission connection with the lifting frame; the linkage plate is in transmission connection with the handwheel; the linkage plate can be in transmission connection with the transmission gear.

[0010] Specifically, a roller is rotatably connected below the lifting frame; a combined chute is provided on the linkage plate and is slidably connected to the roller; the combined chute includes an inclined chute arranged obliquely and a flat chute horizontally arranged and communicating with the upper end of the inclined chute; a transmission rack capable of being in transmission connection with the transmission gear is provided on the linkage plate; only when the roller is located in the flat chute, the transmission rack is in transmission connection with the transmission gear.

[0011] When the lifting frame is at the lower limit position, the roller is at the bottom of the inclined chute, and the linkage plate slides, so that the inclined chute drives the roller to move upward, thereby driving the lifting frame to move upward; when the lifting frame is at the upper limit position, the roller slides from the inclined chute into the flat chute, the transmission rack is in transmission connection with the transmission gear, and the linkage plate continues to slide to drive the needle plate to extend, while the lifting frame does not move.

[0016] Furthermore, a locking screw is rotatably connected to the base plate; a locking groove facing the locking screw is arranged at the upper end of the installation frame; the locking screw can be clamped in the locking groove.

[0017] Furthermore, two insertion openings clamped to the installation frame are symmetrically arranged at the lower end of the splicing plate; the splicing plate has multiple models, and the widths of the splicing plates of each model are different.

[0018] Furthermore, two parallel tracks are arranged at the upper end of the chassis; two groups of translation wheel sets respectively facing the tracks are arranged at the lower end of the installation frame; the translation wheel set includes at least two translation wheels rotatably connected to the lower end of the installation frame; the translation wheels abut against the upper end of the tracks; at least one handle is arranged on the outer periphery of the installation frame.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] 1. When the lifting frame is located below, the lifting frame and the splicing plate form a horizontal tabletop, which is convenient for replacing and adjusting the position of the sponge. When the lifting frame is located above, the needle plate inserts into and clamps the sponge, and the sponge is stably fixed, so that operations such as chamfering can be realized.

[0021] 2. Due to the compressible property of the sponge, the clamping force of the sponge cannot be too large. The sponge is fixed by inserting a needle plate into the sponge.

[0022] 3. The fixing part and the splicing board are detachably arranged, and the two fixing parts can be compatible with sponges of different sizes, expanding the processing content.

[0023] 4. The rotation of the handwheel can drive the movement of the lifting frame and the needle plate in sequence, realizing the clamping and loosening of the sponge, simplifying the operation steps of the operator, and helping to improve the processing efficiency.
