Description

Technical Field

[0001] The invention relates to the field of cutting machinery in the sponge deep processing industry, and in particular to a sponge cutting anti-displacement device. Background Art

[0002] At present, in the sponge processing industry, how to stably fix the sponge on the work surface when cutting is a difficult problem, especially when the sponge cutting is almost finished, the fixation of the thin sponge with a thickness of 5-10cm is even more difficult. At present, the ways to fix the sponge on the cutting platform in the industry are:

[0003] 1. The sponge workpiece is fixed on the cutting platform through the gauze cloth and then cut after being fixed on the sandpaper cloth. However, the sponge is often displaced during cutting due to the unstable fixation, resulting in substandard cutting quality and low efficiency.

[0004] 2. Apply glue on the cutting platform and then place the sponge workpiece for cutting, which will waste the sponge and require cleaning the glue on the cutting platform;

[0005] 3. The sponge workpiece is adsorbed on the cutting platform for cutting by suction negative pressure, which has the problem of large equipment investment. For the thin sponge of 5-10cm in the later stage, its adsorption capacity is not stable enough and shifting occurs. Summary of the invention

[0006] In view of the above defects, the present application provides a sponge cutting anti-displacement device with a simple structure, saving materials and more stable fixation, and its technical solution is as follows:

[0007] A sponge cutting anti-displacement device comprises a horizontal workbench and beams on both sides below the workbench, a driving shaft and a plurality of driven shafts parallel to the driving shaft are installed below the workbench, the driving shaft and the driven shaft are movably installed in the beam through bushings, a plurality of hooks are fixed on the driving shaft and the driven shaft along the length direction, a pair of through holes are correspondingly provided on the workbench above the hooks, the hooks can freely shuttle through the through holes, a motor is also provided below the workbench, a main pulley is installed at the output end of the motor, corresponding slave pulleys are provided on the driving shaft and the driven shaft, belts are alternately connected between the main pulley and the slave pulley, and between the slave pulleys and the slave pulleys, and the motor drives the driving shaft and the driven shaft to move in the same direction through the rotation of the belt.

[0008] Furthermore, the crochet needle includes a connecting portion, an arcuate portion and a piercing portion, the connecting portion is fixedly connected to the driving shaft and the driven shaft, the arcuate portion is a curved rod with a certain curvature, and the connecting portion, the arcuate portion and the piercing portion are an integrated structure.

[0009] Furthermore, when the hook needle passes through the perforation and the sponge, the top end of the arc-shaped portion is 2-3 cm above the workbench.

[0010] Furthermore, the driving shaft is located at the outermost side below the workbench.

[0011] Furthermore, the driving shaft and the driven shaft are arranged at equal intervals below the workbench, and the hooks are fixed on the driving shaft and the driven shaft at equal intervals.

[0012] According to the above technical scheme, the active shaft and the driven shaft of the present invention are driven to rotate by the belt under the rotation of the motor, so that the hooks fixed on the active shaft and the driven shaft rotate at the same time, and all the hooks penetrate into the sponge from the perforation and then penetrate into another perforation to fix the sponge on the workbench. Due to the special structure of the hook, the sponge is not damaged, which saves materials, and all the hooks are arranged in an orderly manner on the workbench. The hooking force on the lower end surface of the sponge is consistent everywhere, and the fixation can be achieved very stably. Even a thin sponge 11 of 5-10 cm can be firmly fixed and cut.

[0020] The present invention will be further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0021] Embodiment 1

[0022] like Figure 1 , Figure 2 , Figure 3As shown, a sponge cutting anti-shift device comprises a horizontal workbench 1 and beams 2 on both sides below the workbench 1, a driving shaft 3 located at the outermost side below the workbench 1 and a plurality of driven shafts 4 parallel to the driving shaft 3 are installed below the workbench 1, the driving shaft 3 and the driven shaft 4 are arranged at equal intervals below the workbench 1, the driving shaft 3 and the driven shaft 4 are movably installed in the beam 2 through a sleeve (not shown in the figure), a plurality of hooks 5 are fixed on the driving shaft 3 and the driven shaft 4 along the length direction, and the hooks 5 are fixed at equal intervals. Fixed on the driving shaft 3 and the driven shaft 4, a pair of perforations 6 are provided on the workbench 1 above the crochet needle 5 in a one-to-one correspondence, and the crochet needle 5 can freely shuttle in the perforations 6. A motor 7 is also provided under the workbench 1, and a main pulley 8 is installed on the output end of the motor 7. Corresponding slave pulleys 9 are provided on the driving shaft 3 and the driven shaft 4. Belts 10 are alternately connected between the main pulley 8 and the slave pulley 9, and between the slave pulley 9 and the slave pulley 9. The motor 7 drives the driving shaft 3 and the driven shaft 4 to rotate in the same direction through the belt 10.

[0023] Among them, Figure 4 , Figure 5 As shown, the crochet needle 5 of the present invention includes a connecting portion 51, an arcuate portion 52 and a piercing portion 53, wherein the connecting portion 51 is fixedly connected to the driving shaft 3 and the driven shaft 4, and the arcuate portion 52 is a curved rod with a certain curvature, and the connecting portion 51, the arcuate portion 52 and the piercing portion 53 are an integrated structure. When the crochet needle 5 passes through the perforation 6 and the sponge 11, the top end of the arcuate portion 52 is 2-3 cm high from the workbench, so that even a thin sponge 11 of 5-10 cm can be firmly fixed and cut.

[0024] Working principle of the present invention:

[0025] like Figure 5 As shown, the hook 5 is in the return position at this time. When the sponge 11 is placed on the workbench 1, the power is turned on to start the motor 7. Under the external control program, the motor 7 drives the main pulley 8 to rotate 180°, and the main pulley 8 drives the slave pulley 9 to rotate 180° through the belt 10. The slave pulley 9 drives other slave pulleys 9 to rotate 180° in conjunction. Driven by the slave pulley 9, the driving shaft 3 and the driven shaft 4 rotate 180° at the same time, so that all the hooks 5 installed on the driving shaft 3 and the driven shaft 4 rotate 180°, and the piercing part 53 of each hook 5 passes through the perforation 6 at the same time, and the sponge 11 penetrates into another perforation 6, and the sponge 11 is fixed on the workbench 1.
