Description

Technical Field

[0001] The utility model relates to the technical field of foam production processes, in particular to a foam feeding mechanism. Background Art

[0002] Foam is a material obtained by foaming plastic particles. As a lightweight, soft, and shock-absorbing material, it has a wide range of applications in many fields. For example, in the electronics field, it can be used for sound insulation and protection of electronic products such as mobile phones, computers, and tablets; in the automotive industry, it can be used for sound insulation, shock absorption, and heat insulation of components such as car seats, door interior panels, instrument panels, roofs, floors, and engine hoods, etc.

[0003] In foam processing factories, the incoming materials of foam are usually in the form of rolls. In order to cut the foam material into specific sizes and shapes to meet the requirements of different application scenarios, the foam roll materials can be processed by slitting and cutting. By using the slitting processing method, foam sheets or rolls of the required size can be obtained efficiently and accurately.

[0004] Based on this, Chinese Patent CN110757551B discloses a slitting device and a foam adhesive production process, which includes a workbench, a base slidably connected to the workbench, and a slide seat slidably connected to the base. The moving direction of the base is parallel to the transmission direction of the foam. A servo electric cylinder is installed on the workbench through a support frame, and the push rod of the servo electric cylinder is connected to the base; the slide seat is perpendicular to the moving direction of the base. A swing rod is rotatably connected to the bottom surface of the slide seat, and a cutting knife is connected to the end of the swing rod away from the slide seat. A servo cylinder is hinged to the bottom surface of the slide seat, and the piston rod of the servo cylinder is hinged to the swing rod. A driving member for driving the slide seat to move is provided on the base. The foam slitting device disclosed in this patent can improve the slitting efficiency of foam adhesive during large-scale continuous production.

[0005] However, the above-disclosed foam slitting device still has the technical problem of low feeding efficiency. Specifically, in the existing technical solutions, the foam material roll is usually fed in a passive pulling manner. That is, a traction mechanism is arranged after the slitting station, and the traction mechanism is used to pull the material section of the foam material roll to continuously release the material. When the foam is slit, the temporarily fixed and limited position of the cut or slit section is usually cut by a cutting knife; although the traction mechanism located after the slitting station stops the feeding action, due to inertia, the foam material section will be tightened and slightly deformed; and at the position before the foam slitting station, since the unwind reel continues to release a small section of foam raw material, the foam material section at this section will appear loose and wrinkled; it is necessary for the user to manually pull back the unwind reel, otherwise, there will be a deviation in the size of the next cut section. During batch slitting processing, the operator is prone to fatigue and may have poor conditions such as missing pulling or mispulling, which has an adverse impact on the slitting efficiency of the foam.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0025] In the present utility model, unless otherwise clearly defined and limited, the terms "mounted", "connected", "coupled", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements, unless otherwise clearly limited.

[0027] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0028] Please refer to Figures 1 to 4 , a foam feeding mechanism of the present utility model includes: a support base 1, a unwind mechanism 2, a tension wheel group structure 3, an adjusting wheel structure 4 and an adjusting wheel driving mechanism 5; the unwind mechanism 2 is disposed on the upper part of the support base 1, the tension wheel group structure 3 is disposed below the unwind mechanism 2, and the tension wheel group structure 3 is connected to the side surface of the support base 1; the adjusting wheel structure 4 is disposed between the tension wheel group structures 3, the adjusting wheel structure 4 is movably disposed on the side surface of the support base 1, the adjusting wheel driving mechanism 5 is disposed on the other side surface of the support base 1 relative to the adjusting wheel structure 4, and the adjusting wheel driving mechanism 5 is drivingly connected to the adjusting wheel structure 4.

[0029] Specifically, when a foam feeding mechanism of the present utility model is in the working process, a foam material roll to be fed is installed and placed in the unwinding mechanism 2. When the feeding starts, the unwinding mechanism 2 is activated and drives the foam material roll to release a foam material tape. The released foam material tape passes through the tension wheel group structure 3 and the adjusting wheel structure 4 respectively. When the unwinding mechanism 2 stops feeding midway or the slitting station of the next station limits the foam material tape to start slitting processing; to prevent the material tape between the support base 1 and the external slitting station from becoming loose or wrinkled, the adjusting wheel driving mechanism 5 can drive the adjusting wheel structure 4 to slide along the support base 1, so that the foam material tape is tensioned between the tension wheel group structures 3; and when the foam material tape tends to deform due to excessive tension during the feeding process, the adjusting wheel driving mechanism 5 can also drive the adjusting wheel structure 4 to move between the tension wheel group structures 3, thereby reducing the tension of the foam material tape between the tension wheel group structures 3. It can be seen that a foam feeding mechanism of the present utility model can automatically unwind the foam roll material, and moreover, during the feeding process of the foam material tape, the tension of the foam material tape can be automatically adjusted as needed; thus, it is possible to avoid bad phenomena such as looseness or wrinkles of the foam material tape during the feeding process, and thereby improve the feeding efficiency of the foam roll material.

[0030] Furthermore, the unwinding mechanism 2 has an unwinding motor connecting frame 201, an unwinding servo motor 202, a coupling 203, an unwinding rotating shaft 204 and a material tray structure 205; the unwinding motor connecting frame 201 is fixedly arranged on the upper side surface of the support base 1, and the unwinding servo motor 202 is connected to the unwinding motor connecting frame 201; the coupling 203 is respectively connected to the unwinding servo motor 202 and the unwinding rotating shaft 204, and the unwinding rotating shaft 204 passes through the support base 1 and is power-connected to the material tray structure 205. Specifically, after the unwinding servo motor 202 is started, it can drive the unwinding rotating shaft 204 through the unwinding rotating shaft 204 and then drive the material tray structure 205 to rotate forward or backward; thus, the foam roll material placed in the material tray structure 205 can realize the function of winding or unwinding the foam material tape.

[0031] Further, the material tray structure 205 includes a positioning rotating disk 205a, a spacing support shaft 205b, an adjusting rotating disk 205c, and a fastener 205d; the positioning rotating disk 205a is connected to the spacing support shaft 205b, and the spacing support shaft 205b is in power connection with the unwinding rotating shaft 204; the adjusting rotating disk 205c is movably arranged on the spacing support shaft 205b relative to the positioning rotating disk 205a, and the fastener 204d connects the adjusting rotating disk 205c to the spacing support shaft 205b. Specifically, when it is necessary to store and place the foam coil material in the material tray structure 205, only need to unlock the fastener 205d from the end of the spacing support shaft 205b, then remove the adjusting rotating disk 205c from the spacing support shaft 205b, place the foam coil material into the spacing support shaft 205b, and then reinstall the adjusting rotating disk 205c. The spacing between the adjusting rotating disk 205c and the positioning rotating disk 205a can be adjusted, so that materials with different material widths can be placed between them.

[0032] Further, the tension wheel set structure 3 includes a guiding wheel 301, a supporting wheel 302, and a conveying wheel 303; the guiding wheel 301 is arranged below the material tray structure 205, and the guiding wheel 301 is movably arranged on the side of the supporting base 1; the two supporting wheels 302 are relatively spaced and movably arranged on the side of the supporting base 1; the conveying wheel 303 is arranged below the supporting wheel 302, and the conveying wheel 303 is movably arranged on the side of the supporting base 1.

[0033] Further, the adjusting wheel structure 4 includes an adjusting pulley 401, a through-supporting shaft 402, a pulley adjusting moving block 403, and an adjusting guiding frame 404; the adjusting pulley 401 is movably arranged at the lower part between the two supporting wheels 302, the adjusting pulley 401 is movably arranged at the end of the through-supporting shaft 402, the pulley adjusting moving block 403 is arranged on the other side of the supporting base 1 relative to the adjusting pulley 401, and the through-supporting shaft 402 passes through the supporting base 1 and is connected to the pulley adjusting moving block 403; the adjusting guiding frame 404 is arranged on the side of the supporting base 1, and the pulley adjusting moving block 403 is movably connected to the adjusting guiding frame 401.

[0034] Further, the adjusting wheel driving mechanism 5 includes a driving lead screw 501, a driving nut block 502, a driving coupling 503, and a driving servo motor 504; the driving lead screw 501 is movably arranged on the adjusting guiding frame 404, the driving nut block 502 connects the driving lead screw 501 and the pulley adjusting moving block 403 respectively; the driving coupling 503 connects the driving lead screw 501 and the driving servo motor 504 respectively.

[0035] Specifically, when the driving servo motor 504 starts, it can drive the driving lead screw 501 to rotate forward or backward through the driving coupling 503. Thus, the driving nut block 502 can reciprocate on the driving lead screw 501. When the driving nut block 502 moves, it can be linked with the pulley adjusting moving block 403, so that the through support shaft 402 and the adjusting pulley 401 are driven by the pulley adjusting moving block 403.

[0036] More specifically, the support base 1 is provided with a base 101, a side wall structure 102 and a longitudinal chute structure 103. The side wall structure 102 is arranged on the base 101, and the longitudinal chute structure 103 is arranged in the side wall structure 102; the through support shaft 402 passes through the longitudinal chute structure 103 and is respectively connected with the adjusting pulley 401 and the pulley adjusting moving block 403 on both sides of the side wall structure 102.

[0037] Thus, after the foam roll stock releases the foam tape from the material tray structure 205, the user can pass the tape through the outlet wheel 301, and then sequentially pass through a support wheel 302 near the outlet wheel 301, the adjusting pulley 401, and the other support wheel 302, and then pass out from the conveying wheel 303. When the tension of the tape is insufficient, the adjusting pulley 401 moves downward along the longitudinal chute structure 103 under the drive of the driving servo motor 504 to tighten the tape; similarly, when the tension of the tape is too large, the adjusting pulley 401 can move upward along the longitudinal chute structure 103 to loosen the tape.

[0038] In summary, a foam loading mechanism of the present utility model is respectively provided with a support base 1, a unwinding mechanism 2, a tension wheel group structure 3, an adjusting wheel structure 4 and an adjusting wheel driving mechanism 5; the unwinding mechanism 2 is arranged on the upper part of the support base 1, the tension wheel group structure 3 is arranged below the unwinding mechanism 2, and the tension wheel group structure 3 is connected to the side surface of the support base 1; the adjusting wheel structure 4 is arranged between the tension wheel group structures 3, the adjusting wheel structure 4 is movably arranged on the side surface of the support base 1, the adjusting wheel driving mechanism 5 is arranged on the other side surface of the support base 1 relative to the adjusting wheel structure 4, and the adjusting wheel driving mechanism 5 is drivingly connected with the adjusting wheel structure 4. A foam loading mechanism of the present utility model can automatically unwind the foam roll stock, and moreover, during the loading process of the foam tape, the tension of the foam tape can be automatically adjusted as needed; thus, it can avoid bad phenomena such as looseness or wrinkles of the foam tape during the loading process, and thereby improve the loading efficiency of the foam roll stock. Therefore, a foam loading mechanism of the present utility model solves the technical problem of how to improve the loading efficiency of the foam roll stock.
