Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to a feeding device for a pre-needling machine used in nonwoven fabric production. Background Technology

[0002] In the production process of nonwoven fabrics, pre-needling is one of the important processing steps. As a key component of the pre-needling machine, the performance of the feeding device directly affects the production quality and efficiency of nonwoven fabrics.

[0003] Existing feeding devices for pre-needling machines in nonwoven fabric production suffer from problems such as unstable feeding and poor pre-compression effect on the nonwoven fabric. This makes it difficult to guarantee the positional accuracy and uniform stress distribution of the nonwoven fabric during pre-needling, easily leading to defects such as wrinkles and deformation, affecting subsequent processing and product quality. Furthermore, existing feeding devices often lack the flexibility to adjust the pre-compression pressure according to different specifications and materials of nonwoven fabrics, resulting in poor applicability. Therefore, we propose a feeding device for pre-needling machines in nonwoven fabric production to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a feeding device for a pre-needling machine in nonwoven fabric production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A feeding device for a pre-needling machine used in nonwoven fabric production includes a feeding shell. Two rotating shafts are rotatably mounted on the inner walls of the front and rear sides of the feeding shell. Rotating rollers are fixedly mounted on the rotating shafts, and the same feeding belt is driven and sleeved on the two rotating rollers. A lower rotating shaft is rotatably mounted on the inner walls of the front and rear sides of the feeding shell. A lower feeding roller is fixedly mounted on the lower rotating shaft. An upper rotating shaft is rotatably mounted on the inner walls of the front and rear sides of the feeding shell. An upper feeding roller is fixedly mounted on the upper rotating shaft. Multiple U-shaped plates are evenly spaced on the top of the feeding shell. A U-shaped seat is slidably mounted inside the U-shaped plate, and a pre-pressure roller is rotatably mounted inside the U-shaped seat.

[0007] Preferably, a control box is fixedly installed on the front side of the feeding shell, and the same drive shaft is rotatably installed on the top and bottom inner walls of the control box. A drive motor is fixedly installed on the top of the control box, and the output shaft of the drive motor is fixedly connected to the drive shaft.

[0008] Preferably, the front ends of both the lower and upper rotating shafts extend into the control box and are fixedly mounted with driven bevel gears. Two driving bevel gears are fixedly mounted on the drive shaft, and the driving bevel gears mesh with the corresponding driven bevel gears.

[0009] Preferably, the rear ends of both the lower rotating shaft and the rotating shaft extend to the rear side of the feeding shell, and pulleys are fixedly installed on the rear ends of both the lower rotating shaft and the rotating shaft, and the same belt is driven on the two pulleys.

[0010] Preferably, the U-shaped plate has movable holes on its front and rear inner walls, a movable plate is slidably installed in the movable holes, and multiple fixing springs are fixedly installed at the bottom of the movable plate, with the bottom ends of the fixing springs fixedly installed on the U-shaped base.

[0011] Preferably, the top of the movable plate is provided with multiple guide holes, and the top of the U-shaped seat is fixedly installed with multiple T-shaped rods, and the T-shaped rods are slidably connected to the corresponding guide holes.

[0012] Preferably, a fixing plate is fixedly installed on both the front and rear sides of the U-shaped plate, and a guide seat is fixedly installed between the two corresponding fixing plates, and the moving plate is slidably sleeved on the guide seat.

[0013] Preferably, one side of the guide seat is provided with multiple fixing grooves, and one side of the movable plate is provided with a threaded hole, and a fixing bolt is installed in the threaded hole, and the fixing bolt is adapted to the corresponding fixing groove.

[0014] The beneficial effects of this utility model are:

[0015] 1. It has stable feeding and pre-compression performance. The drive motor links all components to make the feeding belt move and transport non-woven fabric. The fixed spring and the pre-compression roller pre-compress the fabric to keep the fabric flat, avoid wrinkles, and improve feeding stability and processing quality.

[0016] 2. It has the performance of accurately conveying nonwoven fabric. The upper and lower rotating shafts drive the upper and lower feeding rollers to rotate. When the feeding belt delivers the nonwoven fabric to the middle, it realizes the pressing and stable conveying of the fabric, ensuring the positional accuracy of the nonwoven fabric in the pre-needling process.

[0017] 3. It has the effect of flexibly adjusting the pre-pressure. By rotating the fixing bolt, the moving plate can be fixed or released, and the height of the pre-pressure roller can be adjusted in the vertical direction, so as to flexibly adjust the pressure of the pre-pressure roller and adapt to the production of non-woven fabrics of different specifications and materials.

Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0027] This application discloses a feeding device for a pre-needling machine used in nonwoven fabric production.

[0028] Reference Figure 1-7A feeding device for a pre-needling machine used in nonwoven fabric production includes a feeding shell 101. Two rotating shafts 102 are rotatably mounted on the front and rear inner walls of the feeding shell 101. Rotating rollers 103 are fixedly mounted on the rotating shafts 102. The same feeding belt 104 is driven and sleeved on the two rotating rollers 103. A lower rotating shaft 201 is rotatably mounted on the front and rear inner walls of the feeding shell 101. A lower feeding roller 202 is fixedly mounted on the lower rotating shaft 201. An upper rotating shaft 203 is rotatably mounted on the front and rear inner walls of the feeding shell 101. An upper feeding roller 204 is fixedly mounted on the upper rotating shaft 203. Multiple U-shaped plates 301 are evenly spaced on the top of the feeding shell 101. A U-shaped seat 306 is slidably mounted inside the U-shaped plate 301. A pre-pressure roller 307 is rotatably mounted inside the U-shaped seat 306.

[0029] In this embodiment, a control box 401 is fixedly installed on the front side of the feeding shell 101. The same drive shaft 402 is rotatably mounted on the top and bottom inner walls of the control box 401. A drive motor 404 is fixedly installed on the top of the control box 401, and the output shaft of the drive motor 404 is fixedly connected to the drive shaft 402. This arrangement allows the power of the drive motor 404 to be stably and efficiently transmitted to the drive shaft 402, providing a reliable power source for the operation of the entire feeding device and ensuring the continuity and stability of the feeding process.

[0030] In this embodiment, the front ends of both the lower rotating shaft 201 and the upper rotating shaft 203 extend into the control box 401 and are fixedly mounted with driven bevel gears 405. Two drive bevel gears 403 are fixedly mounted on the drive shaft 402, and the drive bevel gears 403 mesh with the corresponding driven bevel gears 405. More specifically, the two driven bevel gears 405 are located between the two drive bevel gears 403. Through the meshing transmission of the bevel gears, the power can be redirected and transmitted, precisely controlling the upper rotating shaft 203 and the lower rotating shaft 201 to rotate in opposite directions. This ensures that the upper feeding roller 204 and the lower feeding roller 202 cooperate to complete the pressing and conveying action of the nonwoven fabric, improving the accuracy and stability of the feeding.

[0031] In this embodiment, the rear ends of both the lower rotating shaft 201 and the rotating shaft 102 extend to the rear side of the feeding housing 101, and pulleys 501 are fixedly installed on the rear ends of both the lower rotating shaft 201 and the rotating shaft 102, with the same belt 502 driven onto the two pulleys 501. This belt drive method has a simple structure and smooth transmission, and can reliably transmit the power of the lower rotating shaft 201 to the rotating shaft 102, so that the feeding belt 104 can continuously rotate and transport nonwoven fabric. At the same time, it has a certain overload protection capability, reducing the risk of equipment damage.

[0032] In this embodiment, movable holes 302 are provided on the inner walls of the front and rear sides of the U-shaped plate 301. A movable plate 303 is slidably installed in the movable holes 302, and multiple fixed springs are fixedly installed at the bottom of the movable plate 303. The bottom ends of the fixed springs are fixedly installed on the U-shaped seat 306. Multiple guide holes 304 are provided on the top of the movable plate 303, and multiple T-shaped rods 305 are fixedly installed on the top of the U-shaped seat 306. The T-shaped rods 305 are slidably connected to the corresponding guide holes 304. The cooperation between the fixed springs, T-shaped rods 305, and guide holes 304 can ensure that the pre-pressure roller 307 applies stable pre-pressure to the nonwoven fabric, and can also achieve adaptive adjustment through the elastic deformation of the springs under conditions such as changes in the thickness of the nonwoven fabric, avoiding damage to the nonwoven fabric due to excessive pressure or poor pre-pressure effect due to insufficient pressure.

[0033] In this embodiment, fixing plates 601 are fixedly installed on both the front and rear sides of the U-shaped plate 301. A guide seat 602 is fixedly installed between corresponding fixing plates 601, and a moving plate 303 is slidably sleeved on the guide seat 602. Multiple fixing grooves 701 are provided on one side of the guide seat 602, and a threaded hole 702 is provided on one side of the moving plate 303. A fixing bolt 703 is threaded into the threaded hole 702, and the fixing bolt 703 is adapted to the corresponding fixing groove 701. This structure allows operators to easily and quickly adjust the height and pressure of the pre-pressure roller 307 according to the characteristics of different nonwoven fabrics, enhancing the adaptability of the feeding device to the production needs of various nonwoven fabrics and improving the versatility and practicality of the equipment.

[0034] The working principle of this utility model is as follows: By starting the rotary motor, the drive bevel gear 403 and driven bevel gear 405 work together to drive the upper rotating shaft 203 and the lower rotating shaft 201 to rotate. The upper rotating shaft 203 and the lower rotating shaft 201 rotate in opposite directions. Through the cooperation of pulley 501 and belt 502, the lower rotating shaft 201 drives the rotating shaft 102 to rotate. The rotating shaft 102 drives the feeding belt 104 to rotate through the rotating roller 103. The rotation of the feeding belt 104 can transport the non-woven fabric. At the same time, the fixed spring can apply downward pressure to the U-shaped seat 306 and the pre-pressure roller 307. The pre-pressure roller 307 can pre-press the non-woven fabric on the feeding belt 104. The rotation of 203 and the lower rotating shaft 201 drives the upper feeding roller 204 and the lower feeding roller 202 to rotate. When the feeding belt 104 conveys the nonwoven fabric between the lower feeding roller 202 and the upper feeding roller 204, the rotation of the upper feeding roller 204 and the lower feeding roller 202 can press and convey the nonwoven fabric, thereby feeding the nonwoven fabric into the pre-needle punching machine. By rotating the fixing bolt 703, the fixing bolt 703 can be inserted into or released from the corresponding fixing groove 701, thereby achieving the purpose of fixing and releasing the moving plate 303. Moving the moving plate 303 in the vertical direction can adjust the height of the pre-pressure roller 307, thereby adjusting the pressure of the pre-pressure roller 307 as needed.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
