[0040] Embodiment 1

[0041] This embodiment discloses an auxiliary mechanism for the production of polyurethane sponge, which can remove the burrs generated during the sponge molding process through a mechanical mechanism, and can effectively reduce the labor intensity of operators, improve production efficiency, reduce labor costs, and ensure product quality. Figure 1 The invention mainly comprises a positioning part 1 and a cutting part 2, wherein the cutting part 2 is arranged at the side of the positioning part 1. The positioning part 1 is used to position the sponge 3 to be cut, and the cutting part 2 is used to cut the burrs of the sponge 3 to be cut after being positioned. See the following content for details.

[0042] To position the sponge to be cut, see Figure 2The positioning part 1 includes a positioning base 101 and an upper positioning frame 102. The upper positioning frame 102 includes a side plate 121. The upper positioning frame 102 and the side plate 121 are arranged above the positioning base 101. In this embodiment, the sponge 3 to be cut is placed inside the positioning base 101, and the positioning base 101 is adapted to the specifications of the sponge 3 to be cut.

[0043] For details, see Figure 2 , the upper limit frame 102 also includes a connecting plate 122 and a reinforcing frame 123. The connecting plate 122 is symmetrically arranged in the middle of the side plate 121. The reinforcing frame 123 is arranged between the connecting plates 122. The connecting plate 122 is adapted to the specifications of the sponge 3 to be cut. The ends of the side plates 121 are arc-shaped ends. The length of the side plates 121 is less than the length of the sponge 3 to be cut. The sponge 3 to be cut is positioned by the upper limit frame 102, thereby ensuring the position of the sponge 3 to be cut and ensuring the accuracy when removing the burrs.

[0044] Also, see Figure 6 In this embodiment, the reinforcing frame 123 is an H-shaped reinforcing frame. A lifting cylinder 124 is provided at the top of the center position thereof. The height position of the upper limit plate 102 is controlled by the lifting cylinder 124, so that the sponge 3 to be cut can be taken out after the burrs are removed. At the same time, in order to ensure the connection strength between the lifting cylinder 124 and the reinforcing frame, a reinforcing rib plate is provided at the connection between the lifting cylinder 124 and the reinforcing frame 123.

[0045] To achieve the cutting of the rough edges of the sponge to be cut, refer to Figure 1 The cutting part 2 includes a cutting swing rod 201 and a driving mechanism 202. The cutting swing rod 201 is symmetrically arranged on the side plate 121. The driving mechanism 202 is also arranged on the side plate 121. The driving mechanism 202 is connected to the cutting swing rod 201. The cutting swing rod 201 is driven by the driving mechanism 202 to swing, and the swinging simultaneously cuts off the burrs at the edge of the sponge 3 to be cut.

[0046] For details, see Figure 3 The cutting swing rod 201 includes a cutting wire 211, a conductive seat 212 and a swing arm 213. The swing arm 213 is rotatably arranged outside the side plate 121. The conductive seat 212 is arranged at the end of the swing arm 213 through an adjustment rod 214.

[0047] According to the above content, the cutting wire 211 is used as a heating element, and can cut the positioned sponge 3 after being heated by electric current through the conductive seat 212. The conductive seat 212 is used to fix the cutting wire 211 and conduct current to ensure that the heating wire 211 can heat normally. The swing arm 213 is used to control the swing amplitude and position of the heating wire 211 to achieve precise thermal cutting.

[0048] The cutting swing rods 201 are provided in two groups, one group being provided on the outer sides of the side plates 121 on both sides, and the conductive seats 212 of the two groups of cutting swing rods 201 facing each other are connected by cutting wires 211 .

[0049] The two groups of cutting swing rods 201 work simultaneously through the driving mechanism 202, and a more flat and smooth cutting surface can be obtained by heating and accurately cutting the sponge 3 to be cut. In addition, the connection mode between the conductive seat 212 and the heating wire 211 can be adjusted according to actual needs.

[0050] To achieve the swing arm swing, see Figure 1 The end of the swing arm 213 is also connected to a driving mechanism 202. The driving mechanism 202 includes a pull rope 221, a guide wheel 222 and a telescopic rod 223. The telescopic rod 223 is arranged on the outside of the side plate 121 through a retaining hoop 224. The guide wheels 222 are distributed on the side plate 121. One end of the pull rope 221 is fixedly connected to the free end of the telescopic rod 223, and the other end is fixedly connected to the end of the swing arm 213 after being wrapped around the guide wheel 222. A tension spring 218 is also arranged at the end of the swing arm 213. The other end of the tension spring 218 is fixed to the outside of the side plate 121.

[0051] Through the above structure, the operation of the telescopic rod 223 can pull the pull rope 221 to move along the guide wheel 222. The movement of the pull rope 221 simultaneously pulls the swing arm 213 to rotate along its rotating connection, thereby driving the entire cutting swing rod 201 to swing, thereby cutting the sponge 3 to be cut.

[0052] At the same time, in order to ensure the relative position of the side plate and the positioning base 101, see Figure 3 A sensor 225 is also provided at the bottom of the side plate 121, and the sensor 225 is installed in an embedded manner.

[0053] Embodiment 2

[0054] The same points as in the first embodiment are not described in detail, but the difference is that:

[0055] To adjust the cutting position of the conductive seat and cutting wire, refer to Figure 3The front end side of the swing arm 213 is integrally provided with a sliding sleeve 215. The top of the adjusting rod 214 is fixedly connected to the conductive seat 212, and the end thereof passes through the sliding sleeve 215 and is connected with a retaining nut 216. A compression spring 217 is provided between the conductive seat 212 and the sliding sleeve 215. The adjusting rod 214 is a threaded rod, and the swing arm 213 is an extended swing arm 213.

[0056] Through the above structure, when the cutting position of the cutting wire 211 needs to be adjusted, the retaining nut 216 is rotated, and the retaining nut 216 cooperates with the adjusting rod thread, so that the adjusting rod can slide inside the sliding sleeve 215, thereby adjusting the relative position of the cutting wire 211.

[0057] To adjust the position of the entire cutting lever, see Figure 3 , Figure 5 , the swing arm 213 is arranged on the outside of the side plate 121 through the slider 203. The side plate 121 is provided with a slide rail 125 on the outside, and the slider 203 is slidably arranged on the slide rail 125. A rotating shaft 231 is vertically and integrally arranged on the outside of the slider 203. In this embodiment, the swing arm 213 is rotatably arranged on the rotating shaft 231, and a fixing hole penetrating to the slide rail 125 is opened at the axis of the rotating shaft 231. A tightening bolt 232 is arranged inside the fixing hole. The tightening bolt 232 is used to fix the slider 203.

[0058] Through the above structure, the cutting rocker 201 can be driven to move as a whole by sliding the slider 203 on the slide rail 125, so as to further adjust the position of the cutting wire 211.

[0059] Embodiment 3

[0060] The same points as the above embodiment will not be repeated here, but the difference is that:

[0061] The cutting position of the cutting wire is not guaranteed, and its cutting surface is limited, see Figure 3 , Figure 4 , a roller 219 is arranged on the cutting wire 211. The roller 219 is arranged on the cutting wire 211 through a retaining sleeve. A limiting plate 103 is arranged on the side plate 121. A roller groove is opened at the edge of the limiting plate 103, and the roller 219 is arranged in the roller groove of the limiting plate 103.

[0062] The roller 219 is used to move in the roller groove of the limiting plate 103, so as to limit the cutting surface of the cutting wire 211, and at the same time reduce the friction between the cutting wire 211 and the limiting plate 103, to prevent the cutting wire 211 from being worn out after long-term use, thereby ensuring the service life of the cutting wire 211.

[0063] At the same time, the edge of the limiting plate 103 is an arc-shaped edge, and the roller groove is opened at the arc-shaped edge. In this embodiment, the arc-shaped edge of the limiting plate 103 is adapted to the arc of the edge of the sponge 3 to be cut. In addition, it should be noted that the limiting plate 103 in this embodiment is detachably arranged at the end of the side plate 121 by bolts. Through its detachable structure, the cutting surface of the cutting wire 211 can be changed by changing the model of the limiting plate 103, so that it is suitable for cutting of various specifications.

[0064] The working principle of the auxiliary mechanism for the production of polyurethane sponge of the utility model:

[0065] When the device is in use, the sponge to be cut is placed on the positioning base, and the lifting cylinder is started. The operation of the lifting cylinder drives the upper limit frame to descend as a whole. When the lifting limit frame descends to the sensor threshold, it stops descending. At this time, the upper limit frame just stops above the sponge to be cut to fix the sponge to be cut. At the same time, the operation of the telescopic rod drives the pull rope to move, and the pull rope pulls the cutting swing rod, and the cutting swing rod drives the cutting wire to move. While the cutting wire moves, the roller moves in the roller groove of the limit plate to limit the cutting surface of the cutting wire. At the same time, the friction between the cutting wire and the limit plate is reduced to ensure the service life of the cutting wire. The cutting wire moves along the limit plate and cuts the sponge to be cut at the same time.

[0066] When the cutting position of the cutting wire needs to be adjusted, the retaining nut is turned, and the retaining nut cooperates with the adjusting rod thread, so that the adjusting rod can slide inside the sliding sleeve, thereby adjusting the cutting position of the cutting wire. At the same time, by sliding the slider on the slide rail, the cutting swing rod can be driven to move as a whole, thereby further adjusting the position of the cutting wire.

[0067] It should be noted that, when the device is implemented, the structures described in the drawings of this specification are not fixed and unchanging implementation methods. For example, the transmission mode of the driving mechanism 202 and the fixing mode of the slider 203 can be changed according to actual needs, as long as the driving mechanism 202 can drive the cutting swing rod 201 to swing and the slider 203 to be fixed. In addition, the drawings of this specification and the drawings of the abstract are only schematic diagrams, and do not represent the specific structure and actual quantity of the specific implementation.

[0068] Unless otherwise defined, the technical or scientific terms used herein shall have the usual meanings understood by persons of ordinary skill in the field to which the present invention belongs. The use of "one" or "an" and other similar words in the specification and claims of this application does not necessarily indicate a quantitative limitation.

[0069] The exemplary implementation of the present invention is described in detail above with reference to the preferred embodiments. However, it can be understood by those skilled in the art that, without departing from the concept of the present invention, various modifications and variations can be made to the above-mentioned specific embodiments, and various combinations of the various technical features and structures proposed in the present invention can be made without exceeding the protection scope of the present invention.
