Description

Technical Field

[0001] This invention relates to the field of sponge cutting technology, and more specifically to a tool guide device. Background Technology

[0002] Patent CN201611224172.2 describes a fully automatic sponge cutting machine. It includes a wrench holder mechanism comprising an upper drive shaft, a lower drive shaft, a transition shaft, and a wrench shaft. The upper drive shaft is mounted inside the lower end of a suspension bracket, with both ends rotatably mounted on the bracket via bearings. The lower drive shaft is also mounted inside the lower end of the suspension bracket, below the upper drive shaft, with both ends rotatably mounted on the bracket via bearings. The transition shaft is mounted inside the lower end of the suspension bracket, below the lower drive shaft, with both ends mounted on the bracket. The wrench shaft is mounted inside the suspension bracket below the transition shaft. A lower pulley is mounted in the middle of the upper drive shaft, and an upper gear is mounted on the left side of the lower pulley. A lower gear is mounted on the lower drive shaft corresponding to the upper gear on the upper drive shaft, and the upper and lower gears mesh with each other. A small gear is mounted on the lower drive shaft to the right of the lower gear. A transition gear is mounted in the middle of the transition shaft, and a bearing is installed between the transition gear and the transition shaft. The transition gear meshes with the small gear. A wrench gear is designed in the middle of the wrench shaft, and the wrench gear meshes with the transition gear. A wrench groove is transversely formed in the middle of the wrench shaft. With this design, the blade is prone to slipping out of the slot during use. The large contact area between the blade and the slot causes the blade to move rapidly and generate heat. Furthermore, the blade is prone to jamming during operation, especially when tightening the blade. Once jammed, the blade will break under the pull force. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a tool guide device that is rationally designed and has a simple structure, effectively preventing the tool bar from running out of the tool groove during operation and preventing the tool bar from overheating and breaking.

[0004] The technical solution of this invention: A tool guide device is installed on the tool tightening mechanism of a sponge cutter. The tool tightening mechanism includes a tool tightening shaft with a tool groove laterally opened in the middle of the shaft. The device is characterized in that it includes a tool box, which is fitted into the tool groove and seals the opening of the tool groove.

[0005] Further improvements and refinements to the above technical solution are made. The blade box is a guide clamp. A through hole penetrating both ends of the blade groove is provided on the opening side of the blade groove of the blade shaft. The guide clamp is fitted into the through hole. An opening groove is provided on one side of the guide clamp. The opening groove is opposite to the blade groove and together they form the first blade groove. The blade is installed in the first blade groove. When the blade is installed in the first blade groove, the guide clamp blocks the opening of the blade groove of the blade shaft, thereby effectively preventing the blade from running out of the blade groove when it is running.

[0006] Further improvements and refinements to the above technical solution are made. The blade box includes two guide clamps. A through hole is provided on the blade groove of the blade shaft, penetrating both ends of the blade shaft. Both guide clamps are fitted into the through hole. The two guide clamps are located on both sides of the groove opening and the groove bottom, respectively. The two guide clamps contact each other to form a large guide clamp. A square hole is provided in the middle of the large guide clamp, penetrating the large guide clamp. The square hole forms a second blade groove. The blade is installed in the second blade groove. In this way, the guide clamps block the blade groove opening of the blade shaft, thereby effectively preventing the blade from running out of the blade groove when it is running.

[0007] Further improvements and refinements to the above technical solution are made. The guide clamp's opening groove consists of three parts: a groove opening section, a transition section, and a groove bottom section. The groove wall spacing of the groove opening section is consistent with the groove spacing of the cutting shaft. The groove wall spacing of the groove bottom section is less than the thickness of the sponge cutter's blade, and the depth of the groove bottom section is greater than the blade width of the sponge cutter's blade. The transition section is an inclined surface connecting the groove opening section and the groove bottom section. The blade is installed in the first cutting groove, with the blade's edge facing the bottom of the guide clamp's opening groove. Utilizing the three-section design of the guide clamp's opening groove, the transition section effectively prevents excessive blade deviation during operation and effectively prevents the blade's edge from touching the bottom of the opening groove, thus suspending the blade's edge and preventing damage.

[0008] Further improvements and refinements to the above technical solution are made. The square hole is formed by the connection of two opening slots respectively set on the guide clamps. The opening slot of any guide clamp consists of three parts: a slot opening section, a transition section, and a slot bottom section. The spacing between the slot walls of the slot opening section is consistent with the spacing between the slots of the cutting shaft. The spacing between the slot walls of the slot bottom section is less than the thickness of the blade of the sponge cutter, and the depth of the slot bottom section is greater than the blade width of the blade of the sponge cutter. The transition section is an inclined surface connecting the slot opening section and the slot bottom section. The blade is installed in the second slot, and the blade is directly facing the bottom of the opening slot of the same guide clamp. With the three-section design of the opening slot of the guide clamp, the transition section can effectively prevent the blade from excessively deviating during operation, and can effectively prevent the blade from touching the bottom of the opening slot. The blade part is suspended to avoid damage.

[0009] Further improvements and refinements are made to the above technical solution. One end of the guide clamp extends out of the through hole, and a protrusion is provided on the outer periphery of the extended end. The guide clamp is inserted into the through hole, and the protrusion is locked on the end of the screw shaft.

[0010] Further improvements and refinements were made to the above technical solution, wherein the guide clamp is uniformly provided with several U-shaped grooves that penetrate the two side walls of the opening groove of the guide clamp.

[0011] Further improvements and refinements were made to the above technical solution, wherein the through hole is a square through hole and the guide clamps are all square bodies; the square design can effectively prevent the guide clamps from rotating inside the through hole.

[0012] Further improvements and refinements were made to the above technical solution, wherein the through hole is a square through hole and the large guide clamp is a square body; the square design can effectively prevent the large guide clamp from rotating inside the through hole.

[0013] Further improvements and refinements were made to the above technical solution, wherein the hardness of the guide clamp is less than that of the blade. With this design, during the operation of the blade, especially when the blade is being twisted, if the blade gets stuck, the first guide clamp and the second guide clamp will be damaged before the blade under the action of the pulling force, thereby avoiding damage to the blade.

[0014] The advantages of this invention are that it has a reasonable design and simple structure, and can effectively prevent the blade from running out of the blade groove during operation; and prevent the blade from overheating and breaking. Attached Figure Description

[0024] like Figure 1-3As shown in Figures 7-8, a tool guide device is installed on the tool-twisting mechanism 1 of a sponge cutter. The tool-twisting mechanism includes a tool-twisting shaft 2, with a tool groove 3 transversely formed in the middle of the shaft. The device is characterized by including a tool box 4, which is fitted into the tool groove 3, sealing the opening of the groove. The tool box 3 is a guide clamp 5, with a through hole penetrating both ends of the tool-twisting shaft 2 on the opening side of the tool groove 3. The guide clamp 5 is fitted into the through hole, and an opening groove 6 is provided on one side of the guide clamp 5, opposite to the tool groove 3. The first cutting groove is formed, and the cutting strip 12 is installed in the first cutting groove. With the cutting strip 12 installed in the first cutting groove, the guide clamp 5 blocks the opening of the cutting groove 3 of the twisting shaft, thus effectively preventing the cutting strip 12 from running out of the cutting groove 3 during operation. The opening groove 6 of the guide clamp 5 is composed of three parts: a groove opening section 9, a transition section 10, and a groove bottom section 11. The spacing between the groove walls of the groove opening section 9 is the same as the spacing between the cutting grooves 3 of the twisting shaft. The spacing between the groove walls of the groove bottom section 11 is less than the thickness of the cutting strip 12 of the sponge cutter, and the depth of the groove bottom section 11 is greater than the cutting edge of the cutting strip 12 of the sponge cutter. The width of the transition section 10 is a slope connecting the groove opening section 9 and the groove bottom section 11. The blade 12 is installed in the first blade groove, with the blade edge of the blade 12 facing the bottom of the guide clamp's opening groove 6. Utilizing the three-section design of the guide clamp's opening groove 6, the transition section 10 effectively prevents the blade 12 from excessively shifting during operation and effectively prevents the blade edge of the blade 12 from touching the bottom of the opening groove 6, thus suspending the blade edge and preventing damage. One end of the guide clamp 5 extends out of the through hole on the feed side, and a protrusion 7 is provided on the outer periphery of the extended end for guiding... The guide clip 5 is inserted into the through hole, and the protrusion 7 is secured to the end of the screw-twisting shaft 2. The guide clip 5 is evenly provided with several U-shaped grooves 8 that penetrate the side walls of the opening groove. The through hole is square, and all guide clips 5 are square-shaped. This square design effectively prevents the guide clip 5 from rotating within the through hole. The hardness of the guide clip 5 is less than that of the blade 12. With this design, during the blade's operation, especially during screw-twisting, if the blade gets stuck, the guide clip 5 will be damaged before the blade 12 under the action of tensile force, thus preventing damage to the blade 12.

[0025] When in use, first insert the blade 12 into the blade groove 3 of the twisting shaft, then place one side of the blade 12 into the opening groove 6 of the guide clamp, then move the guide clamp 5 along the blade 12 and insert it into the through hole of the twisting shaft 2. The protrusion 7 on the guide clamp locks the shaft end of the twisting shaft 1, completing the installation of the blade box 4, and start the sponge cutter to run normally. Example

[0026] like Figure 4-8As shown, a tool guide device is installed on the tool tightening mechanism 1 of a sponge cutter. The tool tightening mechanism 1 includes a tool tightening shaft 2, with a tool groove 3 transversely opened in the middle of the tool tightening shaft 2; it also includes a tool box 4, which is fitted into the tool groove 3, sealing the opening of the tool groove 3; the tool box 4 includes two guide clamps 5, and through holes penetrating both ends of the tool tightening shaft 2 are provided on the tool groove 3 of the tool tightening shaft. The two guide clamps 5 are fitted into the through holes, and are located on both sides of the groove opening and the groove bottom of the tool groove 3, respectively. The two guide clamps 5 contact each other to form a large guide clamp, with a through hole in the middle of the large guide clamp. The square hole of the guide clamp 5 forms a second cutting groove, and the cutting strip 12 is installed in the second cutting groove. This seals the opening of the cutting groove 3 of the twisting shaft, effectively preventing the cutting strip 12 from running out of the cutting groove 3 during operation. The square hole is formed by the mating of opening slots 6 on two guide clamps 5. Each guide clamp's opening slot 6 consists of three parts: a groove opening section 9, a transition section 10, and a groove bottom section 11. The spacing between the groove walls of the groove opening section 9 is the same as the spacing between the cutting grooves 3 of the twisting shaft, and the spacing between the groove walls of the groove bottom section 11 is less than the thickness of the cutting strip 12 of the sponge cutter. Furthermore, the depth of the bottom section 11 is greater than the blade width of the blade 12 of the sponge cutter. The transition section 10 is an inclined surface connecting the opening section 9 and the bottom section 11. The blade 12 is installed in the second blade groove, and the blade of the blade 12 faces the bottom of the opening groove 6 of the same guide clamp. Utilizing the three-section design of the opening groove 6 of the guide clamp, the transition section 10 can effectively prevent the blade 12 from excessively deviating during operation, and can also effectively prevent the blade of the blade 12 from touching the bottom of the opening groove 6. The blade part of the blade 45 is suspended to avoid damage. One end of the guide clamp 5 extends out of the through hole on the cutting side, and extends out to... A protrusion 7 is provided on the outer periphery of the end, and the guide clamp 5 is inserted into the through hole. The protrusion 7 is stuck on the shaft end of the wrench shaft 2. Several U-shaped grooves 8 are evenly provided on the guide clamp 5, which penetrate the two side walls of the opening groove 6 of the guide clamp. The through hole is a square through hole, and the large guide clamp is a square body. The square design can effectively prevent the large guide clamp from rotating in the through hole. The hardness of the guide clamp 5 is less than the hardness of the blade 12. With this design, during the operation of the blade 12, especially when wrenching, if the blade 12 gets stuck, under the action of the pulling force, the guide clamp 5 will be damaged before the blade, thereby avoiding damage to the blade 12.

[0027] In use, first insert the blade 12 into the blade groove 3 of the twisting shaft, place one side of the blade 12 into the opening groove 6 of a guide clamp, and move the guide clamp 5 along the blade 12 and insert it into the through hole of the twisting shaft 2. The protrusion of the guide clamp 5 locks the shaft end of the twisting shaft 2. Then, place the other side of the blade 12 into the opening groove 6 of another guide clamp, and move the other guide clamp 5 along the blade 12 and insert it into the through hole of the twisting shaft 2. The protrusion of the other guide clamp 5 locks the shaft end of the twisting shaft 2. This completes the splicing and installation of the blade box. Start the sponge cutter to run normally. The installation order of the two guide clamps 5 is not limited.

[0028] Due to the limitations of written expression, while there are objectively infinite specific structures, those skilled in the art can make various improvements, modifications, or variations without departing from the principles of this invention, and can also combine the above-mentioned technical features in an appropriate manner; these improvements, modifications, variations, or combinations, or the direct application of the inventive concept and technical solution to other situations without modification, should all be considered within the scope of protection of this invention.
