Description

Technical Field

[0001] The present invention relates to the technical field of hot pressing and laminating, and particularly to a hot pressing and laminating device for plastic gloves and its usage method. Background Technique

[0002] Plastic gloves are widely used in production and life. During the processing of plastic gloves, two layers of raw materials need to be hot pressed together through a hot pressing and laminating device to form the plastic gloves, and then the waste materials at their edges are torn off.

[0003] The existing patent (publication number: CN217648962U) discloses a hot pressing and laminating device for disposable plastic gloves. It conveys two groups of raw materials through a conveying device, and then hot presses the raw materials through a hot pressing device to form the plastic gloves. At the same time, through the contraction of the first hydraulic cylinder, the conveying device is lifted to separate the formed plastic gloves from the remaining waste materials. Then, the plastic gloves on the hot pressing device are blown onto the discharging device through a jet device, and the formed plastic gloves are discharged through the discharging device. After that, through the extension of the first hydraulic cylinder, the conveying device is reset, and at the same time, the harmful gases generated by the hot pressing raw materials are centrally treated through a purification device. In the above existing technology, the cutting knife is arranged close to the hot pressing die, which easily conducts the temperature to the cutting knife and causes the cut to melt.

A top spring is arranged inside the groove, and the top spring pushes the floating platform upward. The heating die is arranged on the top surface of the floating platform, and an embedding groove is formed on the surface of the floating platform. An inclined groove is formed on the inner side wall of the embedding groove. A slider corresponding to the inclined groove is fixedly arranged on the side surface of the cutting knife, and the cutting knife is slidably connected along the inclined groove through the slider.

[0008] An air-actuated material tearing assembly matched with the floating platform is arranged on the pressing plate and the electric cylinder telescopic rod.

[0009] Preferably, the air-actuated material tearing assembly includes a pressing groove formed in the bottom surface of the pressing plate, and the pressing groove is adapted to the floating platform, the heating die and the cutting knife.

[0010] An air cavity is formed inside the pressing plate, and air holes communicated with the pressing groove are formed on the inner wall of the air cavity. A moving plug is slidably connected in the air cavity.

[0011] The top end of the electric cylinder telescopic rod is fixedly provided with a sliding rod. A sliding hole corresponding to the sliding rod is formed on the surface of the pressing plate, and the pressing plate is slidably connected on the sliding rod through the sliding hole.

[0012] A strip-shaped groove communicated with the sliding hole and the air cavity is formed inside the pressing plate, and a rack is slidably connected in the strip-shaped groove. An inclined tooth meshed with the rack is formed on the side surface of the sliding rod, and the rack is fixedly connected with the moving plug.

[0013] A screening assembly is arranged on the pressing plate and the moving plug.

[0014] Preferably, the screening assembly includes a first bracket fixedly connected to the moving plug, and the first bracket penetrates through the pressing plate and extends to the outside.

[0015] A first through groove is formed on the side surface of the pressing plate, and the first through groove is communicated with the pressing groove. A sealing plate matched with the pressing groove is slidably connected in the first through groove, and a rubber strip is fixedly connected to the sealing plate.

[0016] The first bracket extends to the first through groove and is fixedly connected to the sealing plate.

[0017] A second bracket is fixedly connected to the side of the pressing plate opposite to the first bracket, and the second bracket penetrates through the pressing plate and extends to the outside. A second through groove is formed on the side of the pressing plate opposite to the first through groove, and the second through groove is communicated with the pressing groove. An air extraction plate is slidably connected in the second through groove.

[0018] The second bracket extends to the second sliding groove and is fixedly connected to the air extraction plate.

[0019] Preferably, the sliding rod and the electric cylinder telescopic rod are installed through bolts in the middle.

[0020] Preferably, an anti-leakage filter screen is fixedly arranged inside the air hole.

[0021] Preferably, a baffle cooperating with the air hole is fixedly arranged between the moving plug and the first bracket.

[0022] Preferably, cuts are spaced apart on the surface of the rubber strip.

[0023] A method for using a hot pressing and laminating device for plastic gloves comprises the following steps:

[0024] S1. The films on the two film rollers are pulled by the traction roller and move from the hot pressing table. During this process, the electric cylinder telescopic rod drives the pressing plate to move downward, and gloves are hot pressed out along the heating die. Finally, the cut-off knife is used to cut out the glove opening;

[0025] S2. During the process of the pressing plate moving downward for hot pressing, the floating platform is synchronously pushed to move downward. At this time, the bottom of the cut-off knife contacts the bottom wall of the groove and moves obliquely upward relative to the floating platform along the inclined groove until it fits the heating die to cut out the gloves. When the pressing plate moves upward, the floating platform moves upward to reset. At this time, the cut-off knife moves obliquely downward relative to the floating platform and leaves the heating die;

[0026] S3. When the electric cylinder telescopic rod drives the pressing plate to move downward to contact the hot pressing table for hot pressing, the continuously moving slide rod uses the helical teeth to push the moving plug to move along the rack and jet air out of the air hole. After the hot pressing is completed, the slide rod moves upward along the slide hole and uses the helical teeth to push the moving plug to reset, and suck air along the air hole to tear the hot-pressed gloves from the raw material film and adsorb them in the pressing groove;

[0027] S4. During the process of the pressing plate moving downward to make the moving plug jet air, the first bracket synchronously drives the sealing plate to be withdrawn from the pressing groove and the first through groove, and the second bracket synchronously drives the air extraction plate to be inserted into the second through groove. Subsequently, when the pressing plate moves upward to make the moving plug reset, the first bracket drives the sealing plate to be inserted into the pressing groove to seal the bottom opening, and the rubber strip on the sealing plate synchronously presses the opening of the gloves in the pressing groove. At the same time, the second bracket drives the air extraction plate to be pulled out, and a suction air flow is formed along the pressing groove and the first through groove. When the gloves are airtight, part of the air in the second through groove is filled into the gloves to cause bulging. At this time, the air resistance of the gloves increases and they are pulled off from the rubber strip by the air flow and are drawn out from the second through groove. When the gloves are air-leaking, the air filled into the gloves leaks, and at this time, the air resistance of the gloves cannot be pulled off by the air flow. When the pressing plate moves downward subsequently, the pulled-out sealing plate uses the rubber strip to take out the unqualified gloves.

[0028] Compared with the prior art, the beneficial effects of the present invention:

[0029] In the present invention, by pushing the floating platform downward, the bottom of the cutting knife contacts the bottom wall of the groove and moves obliquely upward relative to the floating platform along the inclined groove until it fits the heating die to cut out the glove. After the pressing plate moves upward, the floating platform moves upward and resets. At this time, the cutting knife moves obliquely downward relative to the floating platform and leaves the heating die. Compared with the existing cutting knife that fits the heating die, the above cutting knife moves upward for cutting during the hot pressing process, separates from the heating die and retracts inward after the hot pressing is completed, effectively reducing the contact time between the two, avoiding heat conduction on the cutting knife, and preventing the problem of hot melting at the glove cutting position, and having better hot pressing and cutting stability.

[0030] In the present invention, the continuously descending sliding rod uses the helical teeth to push the moving plug along the rack and jet air outward along the air holes. After the hot pressing is completed, the sliding rod moves upward along the sliding hole and uses the helical teeth to push the moving plug to reset and suck air along the air holes to tear the glove hot-pressed from the raw material film and adsorb it in the pressing groove. Compared with the existing method of tearing the glove upward along the mold on the raw material, the passive movement of the pressing plate along the sliding rod can generate negative pressure, flexibly tear the glove from the raw material film along the pressing groove and temporarily store it in the pressing groove. On the one hand, it reduces the possibility of damaging the glove due to physical hard pressing, and on the other hand, it can avoid the inconvenience of collection caused by direct dropping.

[0031] In the present invention, the sealing plate is inserted into the pressing groove to seal the bottom opening, and the rubber strip on the sealing plate simultaneously presses the opening of the glove in the pressing groove. At the same time, the second bracket drives the air extraction plate to pull outward, forming a suction air flow along the pressing groove and the first through groove. When the glove is airtight, part of the air in the second through groove fills into the glove to cause it to bulge. At this time, the air resistance of the glove increases and it is dragged off from the rubber strip by the air flow and is drawn out from the second through groove. When the glove is air leaky, the air filled into the glove leaks, and at this time, the air resistance of the glove cannot be dragged off by the air flow. When the pressing plate moves downward subsequently, the pulled-out sealing plate uses the rubber strip to take out the unqualified glove. Compared with the existing method of unified collection after hot pressing, the above moving plug for peeling the glove can detect the glove in the pressing groove by its reciprocating motion, that is, identify the damage and leakage situation by the air flow, and discharge it through different ports according to the breakage and leakage situation of the glove, effectively ensuring the qualified rate of glove production.

Specific embodiments

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Please refer to Figures 1 to 9 , the present invention provides a technical solution: a plastic glove hot pressing and laminating device, including a hot pressing table 1, two film rollers 2 are rotatably arranged on one side of the top of the hot pressing table 1, and a traction roller 3 is rotatably arranged on the other side of the top of the hot pressing table 1. Four electric cylinder telescopic rods 4 are arranged on the top of the hot pressing table 1, and the four electric cylinder telescopic rods 4 are located between the film roller 2 and the traction roller 3. A pressing plate 5 is arranged on the four electric cylinder telescopic rods.

[0044] At the top of the hot press table 1, a heating die 6 and a cutter 7 that cooperate with the pressing plate 5 are respectively arranged. The films on the two film rollers 2 are pulled by the traction roller 3 and move from the hot press table 1. During this process, the electric cylinder telescopic rod 4 drives the pressing plate 5 to move downward, and gloves are hot-pressed out along the heating die 6. Finally, the glove openings are cut out by the cutter 7. A separator 8 is arranged between the heating die 6, the cutter 7 and the hot press table 1.

[0045] The separator 8 includes a groove 81 opened at the top of the hot press table 1, and a floating platform 82 is slidably connected in the groove 81. A top spring 83 is arranged inside the groove 81, and the top spring 83 pushes the floating platform 82 to move upward. During the process of the pressing plate 5 moving downward for hot pressing, the floating platform 82 is synchronously pushed to move downward. The heating die 6 is arranged on the top surface of the floating platform 82, and an embedding groove 84 is opened on the surface of the floating platform 82. An inclined groove 85 is opened on the inner side wall of the embedding groove 84. A sliding block 86 corresponding to the inclined groove 85 is fixedly arranged on the side surface of the cutter 7, and the cutter 7 is slidably connected along the inclined groove 85 through the sliding block 86. When the floating platform 82 moves downward, the bottom of the cutter 7 contacts the bottom wall of the groove 81 and moves obliquely upward relative to the floating platform 82 along the inclined groove 85 until it fits the heating die 6 to cut out the gloves. When the pressing plate 5 moves upward, the floating platform 82 moves upward and resets. At this time, the cutter 7 moves obliquely downward relative to the floating platform 82 and leaves the heating die 6.

[0046] An air-operated material tearing assembly 87 that cooperates with the floating platform 82 is arranged on the pressing plate 5 and the electric cylinder telescopic rod 4.

[0047] In this embodiment, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 9 shown, the air-operated material tearing assembly 87 includes a pressing groove 871 opened on the bottom surface of the pressing plate 5, and the pressing groove 871 is adapted to the floating platform 82, the heating die 6 and the cutter 7.

[0048] An air cavity 872 is opened inside the pressing plate 5, and air holes 873 communicating with the pressing groove 871 are opened on the inner wall of the air cavity 872. A moving plug 874 is slidably connected in the air cavity 872.

[0049] The top end of the electric cylinder telescopic rod 4 is fixedly provided with a sliding rod 875. A sliding hole 876 corresponding to the sliding rod 875 is opened on the surface of the pressing plate 5, and the pressing plate 5 is slidably connected to the sliding rod 875 through the sliding hole 876.

[0050] The inside of the pressing plate 5 is provided with a strip-shaped groove 879 communicating with the sliding hole 876 and the air chamber 872, and a rack 877 is slidably connected in the strip-shaped groove 879. An inclined tooth 878 meshing with the rack 877 is provided on the side surface of the sliding rod 875, and the rack 877 is fixedly connected to the moving plug 874. The downward-moving sliding rod 875 uses the inclined tooth 878 to push the moving plug 874 to move along the rack 877 and jet outwards along the air hole 873. After hot pressing is completed, the sliding rod 875 moves upwards along the sliding hole 876 and uses the inclined tooth 878 to push the moving plug 874 to reset, and sucks in along the air hole 873 to tear the hot-pressed glove from the raw material film and adsorb it in the pressing groove 871.

[0051] A screening assembly 8710 is provided on the pressing plate 5 and the moving plug 874.

[0052] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 9 shown, the screening assembly 8710 includes a first bracket 87101 fixedly connected to the moving plug 874, and the first bracket 87101 penetrates through the pressing plate 5 and extends to the outside.

[0053] A first through groove 87102 is provided on the side surface of the pressing plate 5, and the first through groove 87102 communicates with the pressing groove 871. A sealing plate 87103 matching the pressing groove 871 is slidably connected in the first through groove 87102, and a rubber strip 87104 is fixedly connected to the sealing plate 87103.

[0054] The first bracket 87101 extends to the first through groove 87102 and is fixedly connected to the sealing plate 87103. When the pressing plate 5 moves downward to make the moving plug 874 jet air, the first bracket 87101 synchronously drives the sealing plate 87103 to be withdrawn from the pressing groove 871 and the first through groove 87102. Subsequently, when the pressing plate 5 moves upward to make the moving plug 874 reset, the first bracket 87101 drives the sealing plate 87103 to insert into the pressing groove 871 to close the bottom opening, and the rubber strip 87104 on the sealing plate 87103 synchronously presses and closes the opening of the glove in the pressing groove 871.

[0055] A second bracket 87105 is fixedly connected to the side of the pressing plate 5 opposite to the first bracket 87101, and the second bracket 87105 penetrates through the pressing plate 5 and extends to the outside. A second through groove 87106 is provided on the side of the pressing plate 5 opposite to the first through groove 87102, and the second through groove 87106 communicates with the pressing groove 871. An air extraction plate 87107 is slidably connected in the second through groove 87106.

[0056] The second bracket 87105 extends to the second chute and is fixedly connected to the air extraction plate 87107. When the pressing plate 5 moves downward to make the moving plug 874 jet air, the second bracket 87105 synchronously drives the air extraction plate 87107 to insert into the second through groove 87106. Subsequently, when the pressing plate 5 moves upward to make the moving plug 874 reset, the second bracket 87105 drives the air extraction plate 87107 to pull outwards, forming a suction air flow along the pressure groove 871 and the first through groove 87102. When the glove is airtight, part of the air in the second through groove 87106 is filled into the glove to inflate it. At this time, the air resistance of the glove increases and it is pulled off from the rubber strip 87104 by the air flow and extracted from the second through groove 87106. When the glove is air leaking, the air filled into the glove leaks. At this time, the air resistance of the glove cannot be pulled off by the air flow. When the pressing plate 5 moves downward subsequently, the pulled sealing plate 87103 uses the rubber strip 87104 to take out the unqualified glove.

[0057] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 9 shown, the sliding rod 875 and the electric cylinder telescopic rod 4 are installed in the middle through bolts. After removing the bolts, the sliding rod 875 can be conveniently disassembled to facilitate the user to repair and replace the sliding rod 875 and the helical gear 878.

[0058] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 9 shown, an anti-leakage filter screen is fixedly arranged in the air hole 873. When the negative pressure in the air hole 873 sucks the glove, the anti-leakage filter screen can prevent the glove from being sucked into the hole and causing wrinkles.

[0059] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 9 shown, a baffle plate cooperating with the air hole 873 is fixedly arranged between the moving plug 874 and the first bracket 87101. When the second through groove 87106 sucks the glove from the pressure groove 871, the baffle plate blocks the air hole 873 to avoid the suction of the air hole 873 interfering with the screening process.

[0060] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 9 shown, the surface of the rubber strip 87104 is provided with incisions at intervals. The incision positions do not squeeze the glove, so that the air in the first through groove 87102 can be filled into the glove along here.

[0061] A method for using a hot pressing and fitting device for plastic gloves, comprising the following steps:

[0062] S1. The films on the two film rollers 2 are pulled by the traction roller 3 and move from the hot pressing table 1. During this process, the electric cylinder telescopic rod 4 drives the pressing plate 5 to move downward, and hot presses the gloves along the heating die 6. Finally, the cutter 7 is used to cut out the glove openings.

[0063] S2. During the process of the pressing plate 5 moving downward for hot pressing, the floating table 82 is synchronously pushed to move downward. At this time, the bottom of the cutter 7 contacts the bottom wall of the groove 81 and moves obliquely upward relative to the floating table 82 along the inclined groove 85 until it fits the heating die 6 to cut out the gloves. After the pressing plate 5 moves upward, the floating table 82 moves upward and resets. At this time, the cutter 7 moves obliquely downward relative to the floating table 82 and leaves the heating die 6.

[0064] S3. When the electric cylinder telescopic rod 4 drives the pressing plate 5 to move downward to contact the hot pressing table 1 for hot pressing, the continuously moving downward slide rod 875 uses the helical teeth 878 to push the moving plug 874 to move along the rack 877 and jet air outward along the air hole 873. After the hot pressing is completed, the slide rod 875 moves upward along the slide hole 876 and uses the helical teeth 878 to push the moving plug 874 to reset, and suck air along the air hole 873 to tear the hot-pressed gloves from the raw material film and adsorb them in the pressing groove 871.

[0065] S4. During the process of the pressing plate 5 moving downward to make the moving plug 874 jet air, the first bracket 87101 synchronously drives the sealing plate 87103 to be withdrawn from the pressing groove 871 and the first through groove 87102, and the second bracket 87105 synchronously drives the air extraction plate 87107 to be inserted into the second through groove 87106. Subsequently, when the pressing plate 5 moves upward to make the moving plug 874 reset, the first bracket 87101 drives the sealing plate 87103 to be inserted into the pressing groove 871 to seal the bottom opening, and the rubber strip 87104 on the sealing plate 87103 synchronously presses the opening of the glove in the pressing groove 871. At the same time, the second bracket 87105 drives the air extraction plate 87107 to be pulled out, and a suction air flow is formed along the pressing groove 871 and the first through groove 87102. When the glove is airtight, part of the air in the second through groove 87106 is filled into the glove to cause it to bulge. At this time, the air resistance of the glove increases and it is pulled off from the rubber strip 87104 by the air flow and is extracted from the second through groove 87106. When the glove is air leaky, the air filled into the glove leaks, and at this time, the air resistance of the glove cannot be pulled off by the air flow. When the pressing plate 5 moves downward subsequently, the pulled-out sealing plate 87103 uses the rubber strip 87104 to take out the unqualified gloves.

Those skilled in the art should understand that the present invention is not limited by the above embodiments, and the above embodiments and the descriptions in the specification are only preferred examples of the present invention, which are not used to limit the present invention.

The second bracket (87105) penetrates through the pressing plate (5) and extends to the outside. A second through groove (87106) is formed in the side of the pressing plate (5) opposite to the first through groove (87102), and the second through groove (87106) communicates with the pressing groove (871). An air extraction plate (87107) is slidably connected in the second through groove (87106); The second bracket (87105) extends into the second sliding groove and is fixedly connected to the air extraction plate (87107).

4. A hot pressing and fitting device for plastic gloves according to claim 2, characterized in that: The sliding rod (875) and the electric cylinder telescopic rod (4) are installed in the middle through bolts.

5. The hot pressing and laminating device for plastic gloves according to claim 2, characterized in that: An anti-leakage filter screen is fixedly arranged in the air hole (873).

6. The hot pressing and fitting device for plastic gloves according to claim 3, characterized in that: A baffle that cooperates with the air hole (873) is fixedly arranged between the moving plug (874) and the first bracket (87101).

7. A hot pressing and fitting device for plastic gloves according to claim 3, characterized in that: Notches are formed at intervals on the surface of the rubber strip (87104).

8. A method for using a plastic glove hot pressing and fitting device according to claim 3, comprising the following steps: S1. The films on the two film rollers (2) are pulled by the traction roller (3) and move from the hot pressing table (1). During this process, the electric cylinder telescopic rod (4) drives the pressing plate (5) to move downward, and gloves are hot pressed out along the heating die (6). Finally, the glove mouth is cut out by the cutter (7); S2. During the process of the pressing plate (5) moving downward for hot pressing, the floating table (82) is synchronously pushed to move downward. At this time, the bottom of the cutter (7) contacts the bottom wall of the groove (81) and moves obliquely upward relative to the floating table (82) along the inclined groove (85) until it fits the heating die (6) to cut out the gloves. When the pressing plate (5) moves upward, the floating table (82) moves upward to reset. At this time, the cutter (7) moves obliquely downward relative to the floating table (82) and leaves the heating die (6); S3. When the electric cylinder telescopic rod (4) drives the pressing plate (5) to move downward to contact the hot pressing table (1) for hot pressing, the continuously moving downward sliding rod (875) uses the helical teeth (878) to push the moving plug (874) to move along the rack (877), and jet air outward along the air hole (873). After the hot pressing is completed, the sliding rod (875) moves upward along the sliding hole (876) and uses the helical teeth (878) to push the moving plug (874) to reset, and suck air along the air hole (873) to tear the hot pressed gloves from the raw material film and adsorb them in the pressing groove (871); S4. During the process of the pressing plate (5) moving downward to make the moving plug (874) jet air, the first bracket (87101) synchronously drives the sealing plate (87103) to be withdrawn from the pressing groove (871) and the first through groove (87102). The second bracket (87105) synchronously drives the air extraction plate (87107) to be inserted into the second through groove (87106). When the pressing plate (5) moves upward subsequently to reset the moving plug (874), the first bracket (87101) drives the sealing plate (87103) to be inserted into the pressing groove (871) to seal the bottom opening. At the same time, the rubber strip (87104) on the sealing plate (87103) synchronously presses the opening of the glove in the pressing groove (871). Meanwhile, the second bracket (87105) drives the air extraction plate (87107) to be pulled outwards to form a suction air flow along the pressing groove (871) and the first through groove (87102). When the glove is airtight, part of the air in the second through groove (87106) is filled into the glove to make it bulge. At this time, the air resistance of the glove increases and it is pulled off from the rubber strip (87104) by the air flow and is extracted from the second through groove (87106). When the glove is air leaky, the air filled into the glove leaks. At this time, the air resistance of the glove cannot be pulled off by the air flow. When the pressing plate (5) moves downward subsequently, the pulled-out sealing plate (87103) uses the rubber strip (87104) to take out the unqualified glove.
