Description

Technical Field

[0001] This utility model relates to the field of fixing device technology, specifically a sponge fixing device for a sponge cutting machine. Background Technology

[0002] A sponge is a porous and soft material composed of many small pores, characterized by its lightweight, softness, breathability, and high absorbency. It is commonly used in various cleaning, cosmetic, and industrial applications.

[0003] When cutting sponge blocks, it is sometimes necessary to fix the sponge blocks with a fixing device to prevent them from moving and misaligning during cutting, which would affect the cutting effect. However, traditional fixing devices are not convenient for quickly clamping both sides of sponge blocks of different widths, nor are they convenient for fixing the top of the sponge at multiple points simultaneously, resulting in low fixing efficiency. Therefore, it is necessary to develop a sponge fixing device for sponge cutting machines. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0006] A sponge fixing device for a sponge cutting machine, comprising:

[0007] The mounting platform is a rectangular frame with a hollow inner cavity. A lifting plate is installed in the inner cavity of the mounting platform. The lifting plate has an "I" shaped cross-section when viewed from above. Vertical side clamps are symmetrically slidably installed on the front and rear sides of the lifting plate. The top of the side clamps protrudes from the top wall of the mounting platform, and a horizontal pressure plate protrudes from the side near the center of the top of the mounting platform. The side wall of the side clamps has a vertical sliding opening. A slider is slidably installed inside the sliding opening. The slider has an "H" shaped cross-section when viewed from above.

[0008] The mounting platform has sidewalls fixedly installed around the top of its inner cavity. A transverse double-ended screw with positive and negative threads is rotatably installed between the two sidewalls. The double-ended screw with positive and negative threads is located above the mounting platform and is parallel to it. The two sections of the shaft of each double-ended screw with positive and negative threads are screwed through the sidewalls of the two sliders. A double-headed servo motor is fixedly installed at the top of the inner cavity of the mounting platform. The two output shafts of the double-headed servo motor are respectively connected to one end of a worm gear through a coupling. Worm wheels that mesh with the worm gear are fixedly installed on the shafts of the two double-ended screws with positive and negative threads.

[0009] As a preferred embodiment of the sponge fixing device for a sponge cutting machine according to the present invention, the slider includes a limiting groove formed by recesses on both the front and rear sides, and the inner sidewall of the limiting groove slides perpendicularly against the outer sidewall of the sliding opening.

[0010] As a preferred embodiment of the sponge fixing device for a sponge cutting machine according to the present invention, a vertical electric lifting rod is fixedly installed on the top wall of the inner cavity of the mounting platform, the bottom end of the output rod of the electric lifting rod is fixed at the top center of the lifting plate, and the electric lifting rod and the dual-head servo motor are arranged alternately.

[0011] As a preferred embodiment of the sponge fixing device for a sponge cutting machine according to the present invention, a vertical guide rod is fixedly provided on the four sides of the inner cavity of the mounting platform, and the rod body of the guide rod slides vertically through the front and rear sides of the lifting plate.

[0012] As a preferred embodiment of the sponge fixing device for a sponge cutting machine according to the present invention, the inner side wall of the slider is fixedly provided with a screw hole, and the inner side of the screw hole is screwed to the body of the double-ended screw with positive and negative threads for transmission.

[0026] 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.

[0027] Please see Figures 1-5 The diagram shows a structural schematic of an embodiment of the sponge fixing device for a sponge cutting machine according to this utility model. Please refer to [link / reference]. Figures 1-5 This paper provides a detailed description of a sponge fixing device for a sponge cutting machine.

[0028] A sponge fixing device for a sponge cutting machine includes a mounting platform 100, which is a rectangular frame with a hollow inner cavity. A lifting plate 101 is provided in the inner cavity of the mounting platform 100. The top cross-section of the lifting plate 101 is "I" shaped. Vertical side clamps 102 are symmetrically slidably arranged on the front and rear sides of the lifting plate 101. The top of the side clamps 102 protrudes from the top wall of the mounting platform 100, and a horizontal pressure plate 103 is provided on the side near the center of the top of the mounting platform 100. A vertical sliding opening 104 is opened on the side wall of the side clamps 102. A slider 105 is slidably arranged on the inner side of the sliding opening 104. The top cross-section of the slider 105 is "H" shaped.

[0029] The mounting platform 100 has side walls 200 fixedly installed around the top of its inner cavity. A transverse double-ended screw 201 with positive and negative threads is rotatably installed between the two side walls 200. The double-ended screw 201 with positive and negative threads is located above the mounting platform 100 and is parallel to the mounting platform 100. The left and right sections of the shaft of each double-ended screw 201 are screwed through the side walls of two sliders 105 respectively. The two double-ended screws with positive and negative threads rotate in the same direction. A double-headed servo motor 202 is fixedly installed at the top of the inner cavity of the mounting platform 100. The two output shafts of the double-headed servo motor 202 are respectively connected to one end of a worm gear 203 through a coupling. Worm wheels 204 that mesh with the worm gear 203 are fixedly installed on the shafts of the two double-ended screws with positive and negative threads 201.

[0030] Wherein: the slider 105 includes front and rear concave limiting grooves 106, the inner sidewall of the limiting groove 106 is perpendicularly attached to the outer sidewall of the sliding opening 104 and slides, the distance between the two front and rear limiting grooves 106 is the same as the inner width of the sliding opening 104, so that the slider 105 cannot rotate in the sliding opening 104, so that the slider 105 can pull the side clamp 102 to move left and right, or move up and down along the sliding opening 104;

[0031] Wherein: a vertical electric lifting rod 107 is fixedly installed on the top wall of the inner cavity of the mounting platform 100. The bottom end of the output rod of the electric lifting rod 107 is fixed at the top center of the lifting plate 101. The electric lifting rod 107 and the dual-head servo motor 202 are arranged alternately. When the electric lifting rod 107 is started, it pushes the lifting plate 101 down, thereby causing all the side clamps 102 and the lower pressure plate 103 to fall.

[0032] Wherein: The inner cavity of the mounting platform 100 is fixedly provided with vertical guide rods 108 on the four sides. The rod body of the guide rod 108 slides vertically through the front and rear sides of the lifting plate 101. When the lifting plate 101 is raised or lowered, it slides along the guide rod 108, which improves the stability of the lifting plate 101.

[0033] Wherein: the inner sidewall of the slider 105 is fixedly provided with a screw hole 206, and the inner side of the screw hole 206 is screwed to the rod body of the double-ended screw 201. When the double-ended screw 201 rotates, it pulls the slider 105 and the side clamp 102 to move in the left and right directions.

[0034] Wherein: the end of the worm gear 203 away from the dual-head servo motor 202 is rotatably provided with a support plate 205 through a bearing sleeve. The top of the support plate 205 is fixed to the top wall of the inner cavity of the mounting platform 100. The support plate 205 improves the stability of the worm gear 203 when it rotates.

[0035] Wherein: The top of the mounting platform 100 has a horizontal through-hole 109 through which the side clamping plate 102 passes and moves laterally. The top of the mounting platform 100 near the through-hole 109 is provided with an anti-slip pad 110. The bottom of the sponge board can be raised by the anti-slip pad 110 to facilitate cutting by the cutting machine.

[0036] In practical use, the sponge board to be cut is placed on top of four anti-slip pads 110. Depending on the width of the sponge board, the dual-head servo motor 202 is started to drive the worm gear 203 to rotate, which in turn drives the positive and negative double-head screw 201 to rotate through the worm wheel 204. This causes the four side clamping plates 102 to move closer to the left and right sides of the sponge board until they are in contact, clamping and fixing the left and right sides of the sponge board. Then, the electric lifting rod 107 is started to push the lifting plate 101 down, which causes all the side clamping plates 102 and the lower pressure plate 103 to descend. After the four lower pressure plates 103 descend, they press down and fix the top and four sides of the sponge board, achieving multi-point fixation of the sponge board at the same time, thus facilitating the cutting machine to cut.

[0037] 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.
