Description

Technical Field

[0001] This invention relates to a PVC glove production apparatus, and more particularly to a washing and drying apparatus for the post-processing of PVC gloves, belonging to the technical field of PVC glove production equipment. Background Technology

[0002] During the production and processing of PVC gloves, they need to be dried. Generally, the PVC gloves are put on a hand mold, and the hand mold is driven by a conveyor belt to circulate. During its movement, a hot air blower heats the surface of the gloves, causing the surface moisture to evaporate quickly. However, because there is moisture inside the gloves, especially in the finger area, it is difficult to effectively clean and dry them.

[0003] To address the problem that existing washing and drying devices struggle to effectively clean and dry gloves, especially the inner finger areas, due to moisture inside, this invention proposes a novel solution. Summary of the Invention

[0004] The main objective of this invention is to address the shortcomings of existing technologies by providing a washing and drying device and its control method for the post-processing of PVC gloves.

[0005] The objective of this invention can be achieved by adopting the following technical solution:

[0006] A washing and drying device for post-processing PVC gloves includes a housing. A semi-circular processing box is fixedly connected to the top of the housing. A stepper motor is installed inside the housing. The output end of the stepper motor is connected to a turntable located on the top of the housing. Multiple circumferentially distributed support mechanisms are installed on the turntable. A washing mechanism and a drying mechanism are sequentially arranged on the processing box along the rotation direction of the turntable. Each support mechanism includes a rotating shaft rotatably mounted on the turntable. Two symmetrically distributed half-hand molds are movably mounted on the top of the rotating shaft. A lifting plate located at the bottom of the half-hand molds is slidably mounted on the outside of the rotating shaft. The lifting plate can drive the two half-hand molds away from each other. An arc-shaped slide rail located at the bottom of the lifting plate and capable of driving the lifting plate up and down is connected to the inner wall of the processing box on the side away from the turntable.

[0007] Preferably, the height of both ends of the arc-shaped slide is lower than the height of the middle part, the turntable has a rotating hole that mates with the rotating shaft, and the bottom end of the rotating shaft is threaded with a nut located at the bottom of the turntable.

[0008] Preferably, a rotating wheel located at the top of the turntable is fixedly connected to the outer wall of the rotating shaft, a track that cooperates with the rotating wheel is provided below the arc-shaped slide, an anti-slip ring is connected to the outer side of the rotating wheel, a limit strip is fixedly connected to the outer wall of the rotating shaft, and a limit groove that cooperates with the limit strip is opened in the middle of the lifting plate.

[0009] Preferably, the semi-hand mold and the rotating shaft are rotatably connected by a connecting rod, and the bottom of the semi-hand mold is connected to a sliding rod that is slidably connected to the lifting plate. The bottom end of the sliding rod is connected to a base plate located at the bottom of the lifting plate.

[0010] Preferably, the top of the rotating shaft is connected to a fixed rod that is rotatably connected to the connecting rod, the top of the lifting plate is provided with a sliding groove that cooperates with the sliding rod, and a spring is installed on the outer wall of the rotating shaft between the lifting plate and the fixed rod.

[0011] Preferably, the bottom of the lifting plate is provided with a groove, and a rotating ball is installed in the groove.

[0012] Preferably, the cleaning mechanism includes a water pump installed on the top of the treatment tank, the output end of the water pump is connected to a first water outlet pipe located on the inner wall of the top of the treatment tank, and a second water outlet pipe located below the arc-shaped slide. A shower head is connected to the first water outlet pipe, and a spray nozzle is connected to the second water outlet pipe.

[0013] Preferably, the drying mechanism includes a hot air blower installed on the top of the processing box. The output end of the hot air blower is connected to a first air outlet pipe, a second air outlet pipe, and a third air outlet pipe. The first air outlet pipe is located on the top of the processing box, the second air outlet pipe is located on the side wall of the processing box, and the third air outlet pipe is located below the arc-shaped slide.

[0014] A control method for a washing and drying device for the post-treatment of PVC gloves includes:

[0015] Step 1: Put the PVC gloves on the two half-hand molds on the outside of the processing box. The stepper motor drives the turntable to rotate, thereby driving the support mechanism into the processing box. After entering the processing box, the lifting plate moves upward under the action of the arc slide, causing the two half-hand molds to move away from each other, thereby opening the PVC gloves. The interaction between the turntable and the track causes the PVC gloves to rotate.

[0016] Step 2: Upon reaching the cleaning unit, the water pump washes the outside of the PVC gloves through the first water outlet pipe and the shower head, and washes the inside of the PVC gloves through the second water outlet pipe and the spray nozzle.

[0017] Step 3: The turntable continues to rotate, positioned between the washing and drying mechanisms. Water from inside and outside the PVC gloves will flow into the treatment tank under gravity, and then the turntable continues to rotate.

[0018] Step 4: When the glove reaches the drying unit, the hot air blows air through the first air outlet to dry the top of the PVC glove, through the second air outlet to dry the sides of the PVC glove, and through the third air outlet to dry the inside of the PVC glove.

[0019] Step 5: After drying is complete, the turntable continues to rotate. During the process of rotating out of the processing box, the lifting plate moves down under the action of the arc-shaped slide, which brings the two half-hand molds closer to each other. When they are completely rotated out of the processing box, the two half-hand molds merge together, and the personnel remove the washed and dried PVC gloves.

[0020] Preferably, a drain pipe is connected to the bottom of the processing box.

[0021] The beneficial technical effects of the present invention are as follows: The washing and drying device for PVC gloves according to the present invention, by setting two half-hand molds, which are divided into two halves of a single hand mold, can move closer and further apart, thus facilitating the loading and unloading of PVC gloves when they are joined, and opening them when they are opened, thus facilitating the washing and drying of the inner side and the cleaning of the fingers; by setting the lifting plate and the arc-shaped slide, the lifting plate can be automatically raised and lowered when the turntable rotates, thereby realizing the opening and closing of the two half-hand molds; through the washing mechanism and the drying mechanism, washing and drying can be performed first, and drying can be performed simultaneously on the inner and outer sides of the PVC gloves, which is efficient and fast.

[0032] To enable those skilled in the art to understand the technical solution of the present invention more clearly, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0033] like Figures 1-6 As shown, the washing and drying device for PVC glove post-processing provided in this embodiment includes a housing 1. A semi-circular processing box 2 is fixedly connected to the top of the housing 1. A stepper motor 3 is installed inside the housing 1. The output end of the stepper motor 3 is connected to a turntable 4 located at the top of the housing 1. Multiple circumferentially distributed support mechanisms 5 are installed on the turntable 4. A washing mechanism 6 and a drying mechanism 7 are sequentially arranged on the processing box 2 along the rotation direction of the turntable 4. The support mechanism 5 includes a rotating shaft 8 rotatably installed on the turntable 4. Two symmetrically distributed half-hand molds 9 are movably installed on the top of the rotating shaft 8. A lifting plate 10 located at the bottom of the half-hand molds 9 is slidably installed on the outside of the rotating shaft 8. The lifting plate 10 can drive the two half-hand molds 9 away from each other. An arc-shaped slide rail 11 located at the bottom of the lifting plate 10 and capable of driving the lifting plate 10 to rise and fall is connected to the inner wall of the processing box 2 on the side away from the turntable 4. With the two half-hand molds 9, which divide a hand mold into two halves, they can move closer and further apart, making it convenient to load and unload PVC gloves when they are joined together, and to open them when they are opened, making it easier to wash and dry the inside of the gloves and clean the fingers. With the lifting plate 10 and the arc-shaped slide 11, the lifting plate 10 can be automatically raised and lowered when the turntable 4 rotates, thereby realizing the opening and closing of the two half-hand molds 9. With the washing mechanism 6 and the drying mechanism 7, the gloves can be washed first and then dried, and the inside and outside of the PVC gloves can be washed and dried simultaneously, which is efficient and fast.

[0034] In this embodiment, as Figure 1 , Figure 3 and Figure 7 As shown, the height of both ends of the arc-shaped slide 11 is lower than the height of its middle part. The turntable 4 has a rotating hole that mates with the rotating shaft 8. The bottom end of the rotating shaft 8 is threaded with a nut located at the bottom of the turntable 4. The rotating hole and nut facilitate the disassembly and maintenance of the support mechanism 5. The height of both ends of the arc-shaped slide 11 is lower than the height of its middle part, and the height of its lowest end is lower than the height of the lifting plate 10 in its natural state. Therefore, it can drive the lifting plate 10 to rise and fall, thereby realizing the opening and closing of the two half-hand molds 9.

[0035] In this embodiment, as Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, a rotating wheel 12 located at the top of the turntable 4 is fixedly connected to the outer wall of the rotating shaft 8. A track 14 that cooperates with the rotating wheel 12 is provided below the arc-shaped slide 11. An anti-slip ring 13 is connected to the outer side of the rotating wheel 12. A limit strip 21 is fixedly connected to the outer wall of the rotating shaft 8. A limit groove 22 that cooperates with the limit strip 21 is opened in the middle of the lifting plate 10. The track 14 and the rotating wheel 12 can drive the support mechanism 5 to rotate, thereby improving the washing and drying effect. The anti-slip ring 13 prevents slippage. The limit strip 21 and the limit groove 22 make the lifting plate 10 rotate synchronously with the rotating shaft 8, thereby realizing the synchronous rotation of the semi-hand mold 9.

[0036] In this embodiment, as Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the semi-hand mold 9 and the rotating shaft 8 are rotatably connected by a connecting rod 15. The bottom of the semi-hand mold 9 is connected to a slide rod 16 that is slidably connected to the lifting plate 10. The bottom end of the slide rod 16 is connected to a base plate located at the bottom of the lifting plate 10. The top of the rotating shaft 8 is connected to a fixed rod 17 that is rotatably connected to the connecting rod 15. The top of the lifting plate 10 is provided with a groove 18 that cooperates with the slide rod 16. A spring 19 located between the lifting plate 10 and the fixed rod 17 is installed on the outer wall of the rotating shaft 8. The bottom of the lifting plate 10 is provided with a groove, and a rotating ball 20 is installed in the groove. The slide groove 18 and slide rod 16 are used to connect the semi-manual mold 9 and the lifting platen 10, restricting their movement direction; the rotating ball 20 improves the lifting effect of the lifting platen 10; the spring 19 applies a downward force when the lifting platen 10 moves upward, preventing it from moving too high, and when it exits the processing box 2, the lifting platen 10 moves quickly downward under the action of the spring 19, thus quickly closing the mold and facilitating the removal of the PVC gloves.

[0037] In this embodiment, as Figure 1 , Figure 2 and Figure 4As shown, the cleaning mechanism includes a water pump 23 installed on top of the treatment tank 2. The output end of the water pump 23 is connected to a first water outlet pipe 24 located on the inner wall of the top of the treatment tank 2, and a second water outlet pipe 25 located below the arc-shaped slide 11. A shower head 26 is connected to the first water outlet pipe 24, and a spray nozzle 27 is connected to the second water outlet pipe 25. The shower head 26 sprays water from the top, expanding the spray range, while the spray nozzle 27 provides a strong water flow from the bottom of the lifting plate 10 through its holes, rinsing the inside of the PVC gloves and improving the cleaning effect.

[0038] In this embodiment, as Figure 1 , Figure 2 and Figure 5 As shown, the drying mechanism includes a hot air blower 28 installed on the top of the processing chamber 2. The output end of the hot air blower 28 is connected to a first air outlet pipe 29, a second air outlet pipe 30, and a third air outlet pipe 31. The first air outlet pipe 29 is located on the top of the processing chamber 2, the second air outlet pipe 30 is located on the side wall of the processing chamber 2, and the third air outlet pipe 31 is located below the arc-shaped slide rail 11. Drying can be performed from all directions through the first air outlet pipe 29, the second air outlet pipe 30, and the third air outlet pipe 31, with the third air outlet pipe 31 extending from the bottom of the lifting plate 10 through its perforations.

[0039] A control method for a washing and drying device for the post-treatment of PVC gloves includes:

[0040] Step 1: Put the PVC gloves on the two half-hand molds 9 on the outside of the processing box 2. The stepper motor 3 drives the turntable 4 to rotate, thereby driving the support mechanism 5 into the processing box 2. After entering the processing box 2, the lifting plate 10 moves upward under the action of the arc slide 11, driving the two half-hand molds 9 to move away from each other, thereby opening the PVC gloves. The rotating wheel 12 and the track 14 interact to drive the PVC gloves to rotate.

[0041] Step 2: When the water reaches the cleaning unit 6, the water pump 23 rinses the outside of the PVC glove through the first water outlet pipe 24 and the shower head 26, and rinses the inside of the PVC glove through the second water outlet pipe 25 and the nozzle 27.

[0042] Step 3: Turntable 4 continues to rotate, located between the washing mechanism 6 and the drying mechanism 7. The water inside and outside the PVC gloves will flow into the treatment box 2 under the action of gravity, and then continue to rotate.

[0043] Step 4: When the drying unit 7 is reached, the hot air blower 28 blows air to dry the top of the PVC glove through the first air outlet pipe 29, blows air to dry the side of the PVC glove through the second air outlet pipe 30, and blows air to dry the inside of the PVC glove through the third air outlet pipe 31.

[0044] Step 5: After drying is completed, the turntable 4 continues to rotate. During the process of rotating out of the processing box 2, the lifting plate 10 moves down under the action of the arc slide 11, which drives the two half hand molds 9 to move closer to each other. When they are completely rotated out of the processing box 2, the two half hand molds 9 merge together, and the personnel remove the washed and dried PVC gloves.

[0045] A drain pipe 32 is connected to the bottom of the treatment tank 2. The drain pipe 32 is used to collect the wastewater from the cleaning process.

[0046] In this embodiment, as Figures 1-6 As shown in the figure, the working process of the washing and drying device and its control method for the post-treatment of PVC gloves provided in this embodiment is as follows:

[0047] Step 1: Put the PVC gloves on the two half-hand molds 9 on the outside of the processing box 2. The stepper motor 3 drives the turntable 4 to rotate, thereby driving the support mechanism 5 into the processing box 2. After entering the processing box 2, the lifting plate 10 moves upward under the action of the arc slide 11, driving the two half-hand molds 9 to move away from each other, thereby opening the PVC gloves. The rotating wheel 12 and the track 14 interact to drive the PVC gloves to rotate.

[0048] Step 2: When the water reaches the cleaning unit 6, the water pump 23 rinses the outside of the PVC glove through the first water outlet pipe 24 and the shower head 26, and rinses the inside of the PVC glove through the second water outlet pipe 25 and the nozzle 27.

[0049] Step 3: Turntable 4 continues to rotate, located between the washing mechanism 6 and the drying mechanism 7. The water inside and outside the PVC gloves will flow into the treatment box 2 under the action of gravity, and then continue to rotate.

[0050] Step 4: When the drying unit 7 is reached, the hot air blower 28 blows air to dry the top of the PVC glove through the first air outlet pipe 29, blows air to dry the side of the PVC glove through the second air outlet pipe 30, and blows air to dry the inside of the PVC glove through the third air outlet pipe 31.

[0051] Step 5: After drying is completed, the turntable 4 continues to rotate. During the process of rotating out of the processing box 2, the lifting plate 10 moves down under the action of the arc slide 11, which drives the two half hand molds 9 to move closer to each other. When they are completely rotated out of the processing box 2, the two half hand molds 9 merge together, and the personnel remove the washed and dried PVC gloves.

[0052] The above are merely further embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
