[0023] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] This application discloses a sponge cutting machine with detection function. (Refer to...) Figure 1The sponge cutting machine with detection function comprises a hot-wire cutting part 10, a sponge transmission part 20, at least one set of linear lifting part 30, and a positioning detection part 40. The linear lifting part 30 is provided with an adjustable end, and the adjustable end of the linear lifting part 30 is connected with the side of the sponge transmission part 20, so that the activity of the adjustable end of the linear lifting part 30 can adjust the height position state of the sponge transmission part 20. In this embodiment, the linear lifting part 30 can adopt a ball screw structure driven by a motor, or other lifting control structures known in the prior art. The sponge transmission part 20 is provided with a circulating transmission structure, and the circulating transmission structure is used to make the plurality of sponge blocks to be cut move circularly on the sponge transmission part 20, so that the hot-wire cutting part 10 can be used for slicing multiple times during the movement of the sponge block. The positioning detection part 40 is arranged on one side of the sponge transmission part 20, and the distance between the sponge transmission part 20 and the positioning detection part 40 can be measured in cooperation, so as to control the step of adjusting the height position state of the sponge transmission part 20 by the cooperation control system.

[0025] Referring to Figure 2 The hot-wire cutting part 10 comprises two support rods 11, two bolts 12, two nuts 13 and an electric heating cutting wire 14. The lower ends of the two support rods 11 are supported on a placement surface, and the top ends of the two support rods 11 are each fixedly connected with a bolt 12. Each bolt 12 is further sleeved with a nut 13 in threaded connection with it, and the two ends of the electric heating cutting wire 14 are each sleeved with a sleeve ring on the two bolts 12, and each sleeve ring is each limited and fixed by the adjacent bolt 12 and nut 13, so that the electric heating cutting wire 14 in a taut state can cut the moving sponge block.

[0026] Referring to Figure 3 The sponge transmission part 20 comprises a base 21, two rotating discs 22, two sets of conveyer belts 23 and a first infrared emitter 24. The two rotating discs 22 are each rotationally arranged at the two ends inside the base 21 by a motor drive, and the two sets of conveyer belts 23 are each arranged below the two sets of conveyer belts 23 by a motor drive, and the two rotating discs 22 and the two sets of conveyer belts 23 form a circulating transmission structure in continuous transmission direction, so that the sponge block can be repeatedly transmitted and moved in a circular track by the above-mentioned circulating transmission structure after being placed in the base 21. In addition, the base 21 is connected with the adjustable end of the linear lifting part 30, and the side of the base 21 facing the positioning detection part 40 is provided with the first infrared emitter 24.

[0027] Referring to Figure 5 and Figure 6The positioning detection part 40 comprises a distance adjusting mechanism and a plurality of first infrared receivers 47. The plurality of first infrared receivers 47 are directed towards the sponge transmission part 20, and the plurality of first infrared receivers 47 are each in a position state adjusted by the distance adjusting mechanism. The first infrared transmitter 24 and the plurality of first infrared receivers 47 are used in cooperation, and the adjustment interval of the single position state of the sponge transmission part 20 can be determined by the interaction of the optical signals between the first infrared transmitter 24 and the adjacent two first infrared receivers 47. That is, when the first infrared transmitter 24 and one first infrared receiver 47 are located on the same horizontal line, the reception of the infrared optical signal emitted by the first infrared transmitter 24 by the first infrared receiver 47 can transmit a feedback signal to the control system; then the first infrared transmitter 24 moves to the opposite of another first infrared receiver 47, and the corresponding first infrared receiver 47 transmits a feedback signal to the control system after moving; the control system can determine the position of the first infrared transmitter 24 according to the above feedback signal, and further determine the height of the sponge transmission part 20 rising or falling, and stop moving after the sponge transmission part 20 rises or falls by the height, thereby realizing the accurate adjustment of the height position of the sponge block slicing.

[0028] Referring to Figure 4 The base 21 comprises an outer long circular seat 211, an inner long circular seat 212, and four corner plates 214. The outer long circular seat 211 is provided in a hollow long circular shape, the inner long circular seat 212 is the same shape as the outer long circular seat 211, and the inner long circular seat 212 is fixedly connected to the inner wall of the outer long circular seat 211 by two corner plates 214 on each of the opposite sides. The outer long circular seat 211 and the inner long circular seat 212 form an annular flow channel 213 therebetween, and the width of the flow channel 213 is slightly larger than the length and width of the cut sponge block at each position, so as to avoid the sponge block from being blocked or stuck. Two rotating discs 22 are arranged at the two ends of the flow channel 213, the top of the corner plate 214 is coplanar with the top of the rotating disc 22, and the side of the corner plate 214 close to the rotating disc 22 is provided in an arc shape, so that the sponge block can be moved out to the adjacent corner plate 214 by the centrifugal force after moving to the rotating disc 22. A set of conveyors 23 are arranged below each of the two corner plates 214 on the same side, and a downward inclined slope is further arranged on the side of the corner plate 214 away from the rotating disc 22. Under the action of inertia and the subsequent pushing of the sponge block, the sponge block on the corner plate 214 can slide to the adjacent conveyor 23 and be conveyed to the other rotating disc 22 by the conveyor 23. In addition, an avoidance groove 215 is formed in the middle of the inner long circular seat 212, and the support rod 11 close to the sponge transmission part 20 is arranged in the avoidance groove 215, and the electric heating cutting wire 14 is arranged above the set of conveyors 23.

[0029] Referring to Figure 3, the sponge transmission part 20 further comprises two heightening supports 25, a first distance meter 26 and a second distance meter 27; in addition, the sponge cutting machine provided by the application further comprises a mechanical arm and a pneumatic suction cup structure (not shown in the figure) which are known in the prior art. The two heightening supports 25 are fixedly connected to the top of the inner long circular seat 212, the top of the two heightening supports 25 is respectively provided with the first distance meter 26 and the second distance meter 27, and the first distance meter 26 and the second distance meter 27 are respectively directed towards the two rotating discs 22, and the first distance meter 26 and the second distance meter 27 are used to measure the distance between them and the sponge blocks on the two rotating discs 22. The mechanical arm and the pneumatic suction cup structure are arranged on the side of the sponge transmission part 20, and the pneumatic suction cup structure is driven by the mechanical arm to move, so that the sponge pad cut by the hot-wire cutting part 10 each time can be adsorbed by the pneumatic suction cup structure and transferred to another position by the mechanical arm. The mechanical arm and the pneumatic suction cup structure are both common mechanical structures, and will not be described here. The purpose of the above structure is that when multiple sponge blocks are placed in the sponge transmission part 20 for cutting processing, the first distance meter 26 and the second distance meter 27 can be used to measure the distance of the sponge blocks moving to the two rotating discs 22 respectively. At the beginning, the first distance meter 26 and the second distance meter 27 measure the distance between them and the rotating disc 22 respectively; when the sponge blocks move to the rotating disc 22 and move to another rotating disc 22 after cutting during the transmission, the mechanical arm and the pneumatic suction cup structure can remove the cut sponge pad above the sponge block, at this time, the sponge blocks on the two rotating discs 22 are the sponge blocks that have been cut and the sponge blocks that have not been cut respectively, so that when measuring the distance, the distance measurement results of the first distance meter 26 and the second distance meter 27 have a height difference of the height of a layer of sponge pad; with processing, the distance measurement results of the first distance meter 26 and the second distance meter 27 are the same when one cycle of transmission is completed, at this time, all the sponge blocks have completed the cutting processing, and then the height of the sponge pad corresponding to the sponge transmission part 20 can be adjusted upward. In the repeated cutting process, when the distance measurement results of the first distance meter 26 and the second distance meter 27 have a height difference of the height of a layer of sponge pad, it means that the cutting of all the sponge pads has not been completed; when the distance measurement results of the first distance meter 26 and the second distance meter 27 are the same, it means that the cutting of all the sponge pads has been completed.

[0030] Referring to Figure 5 and Figure 6The spacing adjusting mechanism comprises a guide rail support 41, a driving source 42, a sliding seat 43, an auxiliary support 44, a guide shaft 45, and a number of positioning seats 46 equal to the number of the first infrared receivers 47. The driving source 42 can be an electric push rod, a hydraulic push rod, or a pneumatic push rod, etc., and the sliding seat 43 is slidingly connected to the guide rail support 41 by the driving of the driving source 42. The auxiliary support 44 is formed on the inner side of the guide rail support 41, and the two ends of the guide shaft 45 are fixedly connected to the top and bottom of the auxiliary support 44, respectively. The positioning seats 46 are sleeved on the guide shaft 45 and are slidingly connected thereto, and each positioning seat 46 is formed with a protruding column 461 on the side facing the sliding seat 43. The sliding seat 43 is formed with a number of push grooves 431 equal to the number of the protruding columns 461, and each protruding column 461 is inserted into a corresponding push groove 431. The push grooves 431 have different inclination angles, so that the movement of the sliding seat 43 can drive the translation of the positioning seats 46. As shown in the figure, the push groove 431 at the center is in a horizontal state, so that the protruding column 461 in the push groove 431 does not move during the movement of the sliding seat 43, and the positioning seat 46 at the center does not move. The remaining push grooves 431 on the opposite sides of the central push groove 431 are symmetrically distributed, and the remaining positioning seats 46 can be adjusted at equal intervals by the movement of the sliding seat 43.

[0031] In this embodiment, the two positioning seats 46 at the top and the bottom are each formed with a protrusion outward, and the two protrusions are respectively provided with a second infrared transmitter 48 and a second infrared receiver 49. The interaction of the optical signals between the second infrared transmitter 48 and the second infrared receiver 49 is used to determine the interval between the corresponding two positioning seats 46 of the plurality of positioning seats 46. That is, when calculating the interval between the two positioning seats 46, the distance measured between the second infrared transmitter 48 and the second infrared receiver 49 is subtracted from the height of the plurality of positioning seats 46, and then the result is divided by one less than the number of the positioning seats 46 to obtain the interval between the two adjacent positioning seats 46. The thickness of the sponge cutting can be controlled by controlling the interval between the two adjacent positioning seats 46, and the interval between every two adjacent first infrared receivers 47 is the thickness of the sponge to be cut.

[0032] In this embodiment, the combination of the guide rail support 41, the driving source 42, and the sliding seat 43 can be replaced by the existing air floating guide rail structure in the prior art, so that the parts wear in the spacing adjusting mechanism can be further reduced.

[0033] The system of the present application can also include a control system for controlling the operation of the above-mentioned motor and driving source to perform automatic operation of the sponge block position movement. It should be understood that the control system is not particularly limited and can be implemented by control technology under the prior art, which will not be described here.

[0034] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, so: any equivalent changes made on the structure, shape, principle of the present application should be covered within the protection scope of the present application.
