Description

Technical Field

[0001] This invention relates to the field of protective clothing production equipment technology, and in particular to a waste collection device for protective clothing production. Background Technology

[0002] Medical protective clothing refers to protective garments used by medical personnel and people entering specific medical and health areas. Its function is to isolate pathogens, harmful ultrafine dust, acidic and alkaline solutions, electromagnetic radiation, etc., ensuring personnel safety and maintaining environmental cleanliness. The main material of medical protective clothing is non-woven fabric. The non-woven fabric is cut, sewn, elasticated, bonded, and glued using equipment such as cutting machines, flat sewing machines, overlock machines, and seam sealing machines to create a one-piece protective suit. In the above process, only the cutting operation generates waste. Most existing collection devices rely on the weight of the waste to fall into the collection device. However, this collection method has poor stability and collection efficiency. The mixing of waste and raw materials can affect subsequent production processes and reduce the production efficiency of protective clothing. Summary of the Invention

[0003] The purpose of this invention is to provide a waste collection device for the production of protective clothing. This device can separate waste from raw materials while conveying cut nonwoven fabric raw materials, and continuously collect the waste. It can also collect waste from the cutting area. The collection efficiency is high and the effect is good, without affecting the subsequent production process.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a waste collection device for protective clothing production, comprising a conveyor, a vacuum adsorption device, and a negative pressure suction device. The conveyor includes a mounting frame, with support legs at the bottom. Rotating rollers are rotatably connected to both ends and the middle of the mounting frame, and a drive motor is installed at one end of the middle rotating roller. Main drive belts are provided at both ends of the rotating rollers. The space between adjacent rotating rollers is called the installation area. The installation area is symmetrically divided into two parts: a transmission area and a blank area. The two transmission areas and the blank area are staggered. Several auxiliary drive belts are provided in the transmission area. The vacuum adsorption device includes two vacuum adsorption machines, which are located below the installation area. The top of each vacuum adsorption machine has an adsorption zone and a collection zone. The adsorption zone corresponds to the transmission zone, and the collection zone corresponds to the blank zone. The adsorption zone has a number of adsorption holes evenly distributed, and the collection zone has a number of adsorption elongated holes spaced apart. A vacuum space is provided at the bottom of the adsorption zone and the collection zone, and a centrifugal fan is installed at the bottom of the vacuum space. The negative pressure suction device includes a negative pressure tank. A suction pipe is installed at the inlet of the negative pressure tank. The inlet of the suction pipe is located at the inlet end of the conveyor. A negative pressure fan is installed at the outlet of the negative pressure tank.

[0005] Optionally, the auxiliary drive belts are evenly spaced, with the suction holes located at the intervals.

[0006] Optionally, the adsorption zone and the collection zone are at the same height as the auxiliary drive belt, and the adsorption zone is provided with several grooves that match the auxiliary drive belt, with the auxiliary drive belt located in the grooves.

[0007] Optionally, the vacuum spaces below the adsorption zone and the collection zone are independent of each other, and a centrifugal fan is installed below each vacuum space. A bag filter is installed at the inlet of the centrifugal fan below the collection zone.

[0008] Optionally, a filter screen is installed inside the negative pressure tank, and several support rods are provided on the top of the filter screen.

[0009] Optionally, a first driving wheel and a second driving wheel are provided at the other end of the intermediate rotating roller, a first driven wheel is provided on the rotating roller at one end, and a second driven wheel is provided on the rotating roller at the other end. The first driving wheel and the first driven wheel, and the second driving wheel and the second driven wheel are connected by a transmission belt.

[0010] Optionally, the suction tube is positioned on the side closest to the adsorption zone.

[0011] Optionally, a shaped flexible tube can be used for suction.

[0012] The waste collection device for protective clothing production of the present invention has the following advantages:

[0013] (1) The adsorption zone can adsorb the cut non-woven fabric and then transport it forward under the action of the conveyor belt. The suction pipe can suck up the non-woven fabric waste and separate the waste from the raw material. The raw material can continue to be transported forward to the next production line under the action of the conveyor belt, and the waste can be collected in the negative pressure tank. The negative pressure collection is continuous and will not cause any pulling on the non-woven fabric, and will not affect the stability of cutting and conveying.

[0014] (2) The auxiliary transmission belt is set in the groove, which can better match the adsorption and conveying, and will not cause insufficient suction or inability to convey.

[0015] (3) The suction requirements of the adsorption zone and the collection zone are different. Their independence makes it easy to adjust the suction, which is beneficial to the normal operation of the device.

[0016] (4) The support rod can lift up the waste material, avoid the non-woven fabric from clogging the filter screen, affect ventilation, ensure the stability of the negative pressure environment of the negative pressure tank, and continuously collect waste material. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings. Figure 1 The direction in the middle is the reference.

[0023] like Figures 1-5 As shown, a waste collection device for protective clothing production includes a conveyor, a vacuum adsorption device, and a negative pressure suction device. The conveyor includes a mounting frame 1, with support legs 2 at the bottom. Rotating rollers 3 are rotatably connected to the left and right ends and the middle of the mounting frame 1. A drive motor 4 is installed at the rear end of the middle rotating roller 3. A first driving wheel 5 and a second driving wheel 6 are provided at the front end of the middle rotating roller 3. A first driven wheel 7 is provided at the front end of the left rotating roller 3, and a second driven wheel 8 is provided at the front end of the right rotating roller 3. The first driving wheel 5 and the first driven wheel 7, and the second driving wheel 6 and the second driven wheel 8 are connected by a transmission belt 9. The drive motor 4 can drive the three rotating rollers 3 to rotate synchronously to avoid slippage. Main drive belts 10 are provided on both the front and rear sides of the rotating roller 3. The main drive belts 10 pass around the three rotating rollers 3 and play a conveying role. The space between adjacent rotating rollers 3 is called the installation area. The installation area is symmetrically divided into two parts, namely the transmission area 11 and the blank area 12. The transmission area 11 and the blank area 12 of the left and right installation areas are staggered. Several auxiliary drive belts 13 are provided in the transmission area 11. The auxiliary drive belts 13 pass around the two rotating rollers 3 and are evenly spaced to assist the main drive belts 10 in conveying raw materials.

[0024] The vacuum adsorption device includes two vacuum adsorption machines 14, which are located below the installation area. Each vacuum adsorption machine 14 has an adsorption zone 15 and a collection zone 16 on its top. The adsorption zone 15 corresponds to the transmission zone 11, and the collection zone 16 corresponds to the blank zone 12. The adsorption zone 15 has a plurality of adsorption holes 17 evenly distributed, and a plurality of grooves 18 matching the auxiliary transmission belt 13 are formed on the adsorption zone 15. The auxiliary transmission belt 13 is located within the grooves 18, and the adsorption holes 17 are located at intervals on the auxiliary transmission belt 13. The collection zone 16 has a plurality of elongated adsorption holes 19 spaced apart. These elongated adsorption holes 19 can collect waste from the raw material cutting area. The upper surfaces of the adsorption zone 15 and the collection zone 16 are at the same height as the top of the auxiliary transmission belt 13, allowing for better coordination between adsorption and conveying, preventing insufficient suction or inability to convey. Vacuum spaces 20 are provided at the bottom of the adsorption zone 15 and the collection zone 16. The vacuum spaces 20 below the adsorption zone 15 and the collection zone 16 are independent of each other. A centrifugal fan 21 is provided below each vacuum space 20. A bag filter is installed at the inlet of the centrifugal fan 21 below the collection zone 16 to filter waste and prevent waste from being discharged into the environment and polluting the environment.

[0025] The negative pressure suction device includes a negative pressure tank 22. A suction pipe 23 is installed at the inlet of the negative pressure tank 22. The suction pipe 23 is a fixed flexible hose, which is easy to adjust and suck up waste. The inlet of the suction pipe 23 is located at the inlet end of the conveyor, close to the adsorption zone 15. The adsorption zone 15 can adsorb the raw material, preventing the suction pipe 23 from carrying the raw material when sucking up waste, thus avoiding affecting the normal conveying of the raw material. A filter screen 24 is installed inside the negative pressure tank 22. Several support rods 25 are set on the top of the filter screen 24. A negative pressure fan 26 is installed at the outlet of the negative pressure tank 22. The support rods 25 can lift the waste, preventing the non-woven fabric from clogging the filter screen 24, affecting ventilation, ensuring a stable negative pressure environment in the negative pressure tank 22, and enabling continuous collection of waste.

[0026] The workflow of this invention is as follows: The cutting device can cut the non-woven fabric, separating the entire non-woven fabric into the required raw material and the unwanted waste. The cutting device only has a cutting function and cannot separate the raw material from the waste. The cut non-woven fabric is conveyed to the conveyor. The adsorption zone 15 allows the raw material to adhere tightly to the conveyor and is conveyed to the next mechanism under the action of the main drive belt 10 and the auxiliary drive belt 13. The suction pipe 23 can suck up the waste at the edge, separating the waste from the raw material. During the raw material conveying process, the adsorption elongated holes 19 of the collection zone 16 can suck up the waste at the edge of the raw material. The staggered arrangement of the two collection zones 16 can suck up the entire raw material, improving the waste collection effect. The adsorption elongated holes 19 and the negative pressure tank 22 can provide continuous and stable suction, separating the waste from the raw material in a relatively gentle way and continuously collecting the waste. The collection effect is good and the efficiency is high, which is conducive to improving the production quality and efficiency of protective clothing.
