Description

Technical Field

[0001] This utility model relates to the field of material unloading racks, specifically a quantitative unloading and lifting rack for foam materials. Background Technology

[0002] Foam is a material made by foaming plastic particles. Foam is categorized into PU foam, antistatic foam, and conductive foam. Foam possesses a range of characteristics including elasticity, light weight, rapid pressure-sensitive fixing, ease of use, flexibility, ultra-thinness, and reliable performance. Typically, foam materials are wound and unwound on a feeding rack. Feeding racks are widely used auxiliary tools in production and warehousing, primarily for supporting and storing raw materials and finished products to improve production and work efficiency. Feeding racks are designed to facilitate operation and improve efficiency by placing raw materials or finished products on specific shelves for easy access and storage.

[0003] However, the current feeding racks rely heavily on manual control by operators to ensure that the length of each feeding is consistent. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a foam material quantitative unwinding frame, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a foam material quantitative unwinding frame, including a feeding mechanism, with support frames provided at both ends of the feeding mechanism, a support roller connected between the two support frames, and a quantitative mechanism provided below the support roller. The quantitative mechanism includes a drive motor, a reciprocating screw, and a sliding block. One end of the quantitative mechanism is provided with a material threading tube in front of the feeding mechanism. A blade is installed on the material threading tube near the sliding block. Springs are connected to both ends of the blade, and a blade support is provided below the springs.

[0006] As a further embodiment of this utility model: a stop bar is provided above the support roller between the two support frames, an adjustment groove is provided on the upper surface of the support frame, and a positioning bolt is installed at the end of the stop bar inside the adjustment groove.

[0007] As a further improvement of this utility model: an electrical control mechanism is installed on one side of the feeding mechanism, and a foam material roller is provided above the support roller.

[0008] As a further embodiment of this utility model: the sliding block is meshed and rotatably connected to the reciprocating lead screw, and the drive motor is fixedly connected to the reciprocating lead screw.

[0009] As a further embodiment of this utility model: the blade is fixedly connected to the blade support by the spring, and the blade is movably connected to the feed tube.

[0010] As a further improvement of this utility model, the stop bar is movably connected to the adjustment groove.

[0011] As a further improvement of this utility model, the quantitative mechanism is fixedly connected to the support frame.

[0012] As a further improvement of this utility model, the electronic control mechanism is electrically connected to the drive motor.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By controlling the rotation speed of the drive motor using an electronic control mechanism, the moving speed of the sliding block can be changed. This controls the time it takes for the sliding block to move to the end of the impact blade, thus ensuring that the length of material fed each time is consistent.

[0015] After placing the foam material roller entirely above the support roller, the torque applied to the positioning bolt is controlled to adjust the movement of the stop bar inside the adjustment groove, reducing the distance between the stop bar and the foam material roller. This allows for the placement of foam material rollers of different diameters. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-5 As shown, this embodiment provides a foam material quantitative unwinding frame, including a feeding mechanism 1. Support frames 2 are provided at both ends of the feeding mechanism 1. A support roller 4 is connected between the two support frames 2. A quantitative mechanism 6 is provided below the support roller 4. The quantitative mechanism 6 is fixedly connected to the support frames 2. The quantitative mechanism 6 includes a drive motor 601, a reciprocating screw 602, and a sliding block 603. The drive motor 601 is fixedly connected to the reciprocating screw 602, and the sliding block 603 is meshed and rotatably connected to the reciprocating screw 602. A material threading tube 8 is provided at one end of the quantitative mechanism 6 in front of the feeding mechanism 1. A blade 801 is installed on the side of the material threading tube 8 near the sliding block 603. The blade 801 is movably connected to the material threading tube 8. Springs 605 are connected to both ends of the blade 801. A blade support 604 is provided below the springs 605, and the blade 801 is fixedly connected to the blade support 604 via the springs 605.

[0024] like Figure 2-3 As shown, in this embodiment, a stop bar 3 is provided above the support roller 4 between the two support frames 2. An adjustment groove 201 is provided on the upper surface of the support frame 2. The stop bar 3 is movably connected to the adjustment groove 201. A positioning bolt 202 is installed at the end of the stop bar 3 inside the adjustment groove 201. An electrical control mechanism 7 is installed on one side of the feeding mechanism 1. The electrical control mechanism 7 is electrically connected to the drive motor 601. A foam material roller 5 is provided above the support roller 4.

[0025] The working principle of this utility model is as follows: During use, after placing the foam roller 5 entirely above the support roller 4, the torque applied to the positioning bolt 202 is controlled to adjust the movement of the stop rod 3 within the adjusting groove 201. After reducing the distance between the stop rod 3 and the foam roller 5 for limiting, one end of the foam roller 5 is pulled out, passes under the stop rod 3, and then enters the material feeding tube 8. After extending the end of the foam roller 5 into the operating mechanism, the length of the foam roller 5 is determined according to requirements. Because the speed of winding the foam roller 5 is consistent, the sliding block 603 is recorded as being outside the reciprocating screw 602. The time required for one round trip on the side ensures that the feeding length of the foam roller 5 is consistent. When it is necessary to adjust the feeding length, the rotation efficiency of the drive motor 601 is controlled by the electronic control mechanism 7, which changes the moving speed of the sliding block 603. The sliding block 603 moves to the end position of the impact blade 801, moving the blade 801 into the material tube 8. At the same time, the spring 605 at the other end of the blade 801 is stretched, and the blade 801 cuts the foam roller 5 passing through the material tube 8. When the sliding block 603 returns to its original position, the spring 605 pulls the blade 801 outward to return to its original position.
