[0009] The mounting groove is recessed at the top of the base in front of the cutting groove, and a feeding plate for conveying sponge blocks is slidably arranged at the top of the mounting groove in the front-back direction.

[0010] As a preferred embodiment of the sponge block pressing structure on the sponge cutting machine described in this utility model, the translation mechanism includes a transverse lead screw rotatably disposed between the left and right fixed frames and a transverse guide rod fixed between the left and right fixed frames.

[0014] In a preferred embodiment of the sponge block pressing structure on the sponge cutting machine described in this utility model, when the pressure plate is in a natural falling state, the height of the lower edge of the cutting blade is higher than the height of the lower edge of the pressure roller.

[0015] As a preferred embodiment of the sponge block pressing structure on the sponge cutting machine of this utility model, wherein: a push plate is protruding from the top of the feeding plate on the side away from the cutting groove; side plates are fixedly provided on the left and right sides of the top of the feeding plate; a first horizontal screw is threaded through the side wall of the side plate; a slide rod parallel to the first screw is slidably provided through the side wall of the side plate; a side pressure plate is rotatably provided at the end of the first screw near the middle of the feeding plate; and one end of the slide rod is fixedly connected to the side wall of the side pressure plate.

At this time, the spring is compressed, thereby applying pressure to both sides of the sponge block at the cutting position. The cutting blade then presses down to cut the sponge block. Then, the servo motor is activated to drive the lead screw to rotate, causing the mounting plate to move laterally, thereby driving the cutting blade to cut the sponge block laterally. When the pressure roller rolls, the spring cannot bend due to the set limit rod, so that the spring can always apply downward pressure to the sponge block through the pressure roller, pressing the surface of the area of ​​the sponge block that needs to be cut tightly, reducing the occurrence of unsatisfactory cutting shapes due to the elasticity of the sponge during sponge block cutting.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0033] Please see Figures 1-7 The diagram shows a schematic representation of an embodiment of a sponge block pressing structure on a sponge cutting machine according to this utility model. Please refer to [link / reference]. Figures 1-7 This paper provides a detailed description of a sponge block pressing structure on a sponge cutting machine.

[0034] A sponge block pressing structure for a sponge cutting machine includes a base 100. Fixing frames 101 are fixedly installed on the left and right sides of the top of the base 100. An mounting plate 102 is movable left and right between the fixing frames 101 on the left and right sides via a translation mechanism. A protective frame 103 is raised and lowered at the bottom of the mounting plate 102. The protective frame 103 is a hollow body with an open bottom wall. A cutting blade 104 for cutting the sponge block is rotatably mounted on the inner side wall of the protective frame 103 via a rotating shaft. A motor for driving the rotating shaft and the cutting blade 104 can also be installed on the protective frame 103. A transverse cutting groove 105 is opened at the top of the base 100 directly below the cutting blade 104. The length of the cutting groove 105 is greater than the range of left and right movement of the cutting blade 104.

[0035] The protective frame 103 has horizontally fixed plates 200 symmetrically fixed on its front and rear side walls. A row of vertical springs 201 are fixedly fixed at equal intervals on the bottom wall of the fixed plates 200. A horizontal pressure plate 202 is provided at the bottom of all the springs 201. A row of pressure rollers 203 are rotatably embedded in the bottom of the pressure plate 202 at equal intervals. The lower surface of the pressure rollers 203 protrudes from the lower surface of the pressure plate 202 and rolls along the moving direction of the cutting disc 104. A row of vertical limiting rods 204 are fixedly fixed on the top of the pressure plate 202. The rods of the limiting rods 204 slide through the top wall of the fixed plate 200. The positions of the limiting rods 204 and the springs 201 are one-to-one, and the rods of the limiting rods 204 slide against the inner side of the springs 201. Through the limiting rods 204, the springs 201 will not bend when the pressure rollers 203 roll, so that the springs 201 can always apply downward pressure to the sponge block through the pressure rollers 203.

[0036] The top of the base 100 is recessed in front of the cutting groove 105 and has an installation groove 300. A feeding plate 301 for conveying sponge blocks is slidably disposed on the top of the installation groove 300 in the front-back direction.

[0037] The translation mechanism includes a horizontal lead screw 106 rotatably disposed between the left and right fixed frames 101, and a horizontal guide rod 107 fixed between the left and right fixed frames 101. Connecting blocks 108 are symmetrically fixed on the front and rear side walls of the mounting plate 102. One side wall of the connecting block 108 is driven through by the rod body of the lead screw 106, and the side wall of the connecting block 108 is slidably penetrated by the rod body of the guide rod 107 through a linear bearing.

[0038] A horizontal servo motor 109 is fixedly installed on the outer wall of the fixed frame 101. The output shaft of the servo motor 109 is connected to the end of the lead screw 106 through a coupling. When the servo motor 109 is started, it drives the lead screw 106 to rotate, causing the mounting plate 102 to move laterally, thereby driving the cutting blade 104 to cut the sponge block laterally.

[0039] Wherein: A vertical electric telescopic rod 110 is fixedly installed on the top of the mounting plate 102. The output shaft of the electric telescopic rod 110 slides through the center of the bottom wall of the mounting plate 102 through a linear bearing. The bottom end of the output shaft of the electric telescopic rod 110 is fixed at the center of the top wall of the protective frame 103. When the electric telescopic rod 110 is started, the protective frame 103 and the cutting blade 104 are driven to descend, so that the pressure roller 203 presses down on the sponge block and the cutting blade 104 cuts the sponge block.

[0040] Wherein: a limiting plate 205 with an outer diameter larger than the limiting rod 204 is fixedly provided on the rod body of the limiting rod 204. The limiting plate 205 is located above the fixed plate 200. By setting the limiting plate 205, the spring 201 is prevented from being stretched due to the weight of the pressure plate 202 and the pressure roller 203 for a long time, which would affect its elasticity.

[0041] Wherein: when the pressure plate 202 is in a natural falling state, the height of the lower edge of the cutting blade 104 is higher than the height of the lower edge of the pressure roller 203, ensuring that the pressure roller 203 touches the surface of the sponge block before the cutting blade 104, thereby applying pressure to the sponge block;

[0042] Wherein: A push plate 302 is provided on the top side of the feeding plate 301 away from the cutting groove 105; side plates 303 are fixedly provided on the left and right sides of the top of the feeding plate 301; a first horizontal screw 304 is threaded through the side wall of the side plate 303, and a sliding rod 305 parallel to the first screw 304 is slidably provided through the side wall; a side pressure plate 306 is rotatably provided at one end of the first screw 304 near the middle of the feeding plate 301; one end of the sliding rod 305 is fixedly connected to the side wall of the side pressure plate 306; a sponge block is placed on the top of the feeding plate 301; the distance between the two side pressure plates 306 is adjusted by rotating the first screw 304, so that the inner sides of the two side pressure plates 306 clamp the left and right sides of the sponge block, thereby fixing sponge blocks of different widths and reducing the displacement of the sponge block during cutting;

[0043] The side pressure plate 306 is inverted "L" shape. A vertical second screw 307 is screwed through the top of the side pressure plate 306. A lower pressure plate 308 is fixedly installed at the lower end of the second screw 307. The height of the lower pressure plate 308 is adjusted by the second screw 307. The lower pressure plate 308 presses down on the top of both sides of the sponge block, thereby further fixing sponge blocks of different thicknesses.

[0044] Wherein: A linear motor 309 is fixedly installed on the left side of the bottom wall of the mounting groove 300, and a slide rail 310 is fixedly installed on the right side. The output seat of the linear motor 309 and the slider sliding on the slide rail 310 are both arranged along the moving direction of the feeding plate 301. The output seat of the linear motor 309 and the slider on the slide rail 310 are respectively fixedly installed on the left and right sides of the bottom of the feeding plate 301. Activating the linear motor 309 drives the feeding plate 301 and the sponge block to move, thereby adjusting the cutting position of the sponge block to facilitate cutting.

[0045] The bottom of the feeding plate 301 is fixedly provided with support wheels 311 in an array. The rollers of the support wheels 311 roll on the bottom wall of the mounting groove 300, and the support wheels 311 provide support for the entire feeding plate 301.

[0046] In practical use, the bottom of the sponge block is placed on the cutting groove 105 and the top of the feeding plate 301 respectively. The distance between the two side pressure plates 306 is adjusted by rotating the first screw 304, so that the inner sides of the two side pressure plates 306 clamp the left and right sides of the sponge block. The height of the lower pressure plate 308 is adjusted by the second screw 307. The lower pressure plate 308 presses down on the top of the two sides of the sponge block, thereby further fixing the sponge block. As needed to cut the position of the sponge block, the linear motor 309 is started to drive the feeding plate 301 and the sponge block to move, thereby adjusting the cutting position of the sponge block.

[0047] After determining the position of the sponge block, the linear motor 309 is stopped, and the electric telescopic rod 110 is started to drive the cutting blade 104 and the fixing plate 200 to descend. The two rows of pressure rollers 203 will touch the surface of the sponge block before the cutting blade 104. The electric telescopic rod 110 continues to drive the cutting blade 104 and the fixing plate 200 to descend. At this time, the spring 201 is compressed, thereby applying pressure to both sides of the sponge block at the cutting position. The cutting blade 104 then presses down to cut the sponge block. Then, the servo motor 109 is started to drive the lead screw 106 to rotate, causing the mounting plate 102 to move laterally, thereby driving the cutting blade 104 to cut the sponge block laterally. When the pressure rollers 203 roll, the limit rod 204 prevents the spring 201 from bending, so that the spring 201 can always apply downward pressure to the sponge block through the pressure rollers 203, pressing the surface of the area of ​​the sponge block to be cut, reducing the occurrence of unsatisfactory cutting shapes due to the elasticity of the sponge during sponge block cutting.

[0048] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
