Description

Foam forming processing equipment and foam forming processing method using same

Technical Field

The invention relates to the technical field of production and processing, in particular to foam forming processing equipment and a foam forming processing method using the same.

Background

In the prior art, a method of blanking for two times is generally adopted in a forming process of a small foam product, and a raw material foam is firstly blanked for the first time to form a foam product, and then blanked for the second time to separate the raw material foam from the foam product.

Specifically, referring to fig. 1, the foam product forming apparatus 100 includes a first blanking mechanism 110 provided with a pneumatic cutter 111, a blanking platform 120 acting in cooperation with the pneumatic cutter 111, and a second blanking mechanism 130. A plastic plate is arranged on the blanking platform 120, and the raw material foam 140 is driven by the drawstring mechanism 150 to pass through and move between the plastic plate and the pneumatic cutter 111 along the horizontal direction. After the pneumatic cutter 111 punches the raw material foam 140 for the first time, the punched foam product cannot be separated immediately and still moves together with the raw material foam 140. And then a second blanking is performed from below the raw foam 140 by the second blanking mechanism 130 to completely release the foam product. Finally, the foam product is transported to the next process by the product transfer mechanism 160 above the foam product.

The above production method has problems in that:

1. owing to adopt the secondary blanking, make the course of working loaded down with trivial details relatively to because raw materials bubble is cotton itself has certain elasticity, makes raw materials bubble cotton after the blanking of first time, when being pulled to second blanking mechanism by stretching strap mechanism again, can cause the die-cut position of second time to have deviation, location inaccurate, thereby makes the cotton product of bubble cut off unclear, have the burr.

2. Because the secondary punching position of the foam product at each time is possibly inconsistent, the grabbing position of the product transferring mechanism is also inconsistent, and the automation consistency and the equipment stability of the processing equipment are influenced.

3. Because the cutting knife for the first blanking is generally in a sheet type, the cutting knife is quickly worn and easily becomes dull due to frequent blanking, and the cutting effect is poor; meanwhile, the plastic plate below is punched by the cutter every time, and grooves with different depths are cut in the flat plate after the plastic plate is used for a period of time, so that the foam product is punched and does not fall off easily, and the products are adhered.

4. Because the cotton product adhesion of bubble, the cotton product periphery of bubble is uneven for the die-cut position that second blanking mechanism detected is inaccurate, influences the blanking effect of secondary.

5. The cutting knife for punching is generally a special-shaped sheet, so the manufacturing cost is high and the forming is difficult.

Therefore, there is a need for a foam molding apparatus and a foam molding method using the same to at least partially solve the problems of the prior art.

Specific embodiments of the present invention will now be described in more detail with reference to the accompanying drawings, which illustrate representative embodiments of the invention and do not limit the invention.

According to a first aspect of the present invention, there is provided a foam forming processing apparatus for punching a stock foam into a plurality of discrete foam products. The raw material foam is preferably a foam belt.

As shown in fig. 2 and 3, the foam molding processing apparatus 200 generally includes a raw material conveying mechanism 210, a product transfer mechanism 220, and a die cutting mechanism 300. The material conveying mechanism 210, the product transferring mechanism 220, and the punching mechanism 300 may be fixedly disposed on one support platform 230. The die-cutting mechanism 300 is disposed downstream of the stock foam 10 conveyance direction D1 for die-cutting the stock foam 10 to form the separated foam products 20. The raw material conveying mechanism 210 is disposed upstream of the die-cutting mechanism 300, and is used for conveying the raw material foam 10 to the die-cutting mechanism 300. The product transfer mechanism 220 is disposed downstream of the die-cutting mechanism 300, and is configured to transfer the separated foam products 20 die-cut by the die-cutting mechanism 300 to the next process.

Specifically, the die cutting mechanism 300 generally includes a body member 310, a punch 320, and a die cutting drive 330. The body member 310 serves to fix the punch 320 and the die-cutting driving member 330, and to restrain the raw foam 10. Specifically, the raw material foam 10 can be moved by the raw material conveying mechanism 210 through the body member 310 along the conveying direction D1. A punch 320 is disposed within the body member 310, and one end of the punch 320 is connected to a retractable end of the punching drive 330, so that the punch 320 can reciprocate within the body member 310 in the punching direction D2 to punch the raw foam 10 and push the foam product 20 to the outside of the body member 310.

It should be understood that although the conveying direction D1 is shown in fig. 2 as being perpendicular to the die cutting direction D2. Specifically, the conveying direction D1 of the raw foam 10 is a horizontal direction from left to right, and the punching direction D2 of the punching mechanism 300 is an upward vertical direction. However, the present invention is not limited to this, and the conveying direction D1 may be another direction different from the punching direction D2, for example, the conveying direction D1 is a vertical direction, and the punching direction D2 is a horizontal direction, and all the design concepts that can achieve the present invention belong to the protection concept of the present invention.

As shown in fig. 4 and 5, the body member 310 includes a fixed base plate 311, a plurality of guide posts 312, a guide plate 313 provided with a first through hole 3131, and an upper plate 314 provided with a second through hole 3141. The fixed base plate 311 is located between the guide plate 313 and the die-cutting driver 330, and serves to connect the punch 320 with the retractable end of the die-cutting driver 330, so that the fixed base plate 311 can move together with the punch 320 while the die-cutting driver 330 drives the fixed base plate 311. The peripheral portion of the fixed board 311 is movably connected to the plurality of guide posts 312 so that the fixed board 311 can move relative to the guide posts 312 in the punching direction D2. The upper die plate 314 is located outside the guide plate 313 in the blanking direction D2 such that the punch 320 is guided by the first through hole 3131 and can move to the second through hole 3141 in the blanking direction D2. In other words, when the punch 320 is in the initial position, the punch 320 is located within the first through hole 3131, and when the punch 320 is in the pushing position, the end of the punch 320 moves upward into the second through hole 3141. Thereby, the punch 320 can be moved from the home position to the push position along the first and second through

holes

3131 and 3141 to achieve the punching process of the raw material and the pushing process of the product.

Specifically, the periphery of the upper plate 314 is fixedly connected with the tops of the plurality of guide posts 312 to support the upper plate 314. The guide plate 313 is fixedly connected to and accurately positioned with the upper die plate 314 by a positioning pin 315, and the guide plate 313 abuts against the upper die plate 314. One side of the guide plate 313 abutting against the upper mold plate 314 is a flat surface, and is provided with a groove 3132 for passing the raw material foam 10 therethrough, and a first through hole 3131 is formed in the groove 3132.

Preferably, the side of the upper plate 314 abutting against the guide plate 313 is a plane, and the longitudinal sectional shape of the groove 3132 is configured to correspond to the longitudinal sectional shape of the raw material foam 10. Therefore, when the raw material foam 10 passes through the groove 3132, the raw material foam 10 can be completely limited in the groove 3132 in other directions relative to the conveying direction D1, so that the raw material foam 10 is not driven to move under the action of the punch 320 in the punching process, and the punching efficiency and the product quality are not affected.

Preferably, a recess 3142 is provided on the opposite side of the upper plate 314 from the guide plate 313, and the second through hole 3141 is formed in the bottom of the recess 3142. This makes it possible to more easily position the grasping portion 222 of the product transfer mechanism 220 on the die cutting mechanism 300. In the illustrated embodiment, although the guide plate 313 and the upper mold plate 314 are configured as two separate members, the guide plate 313 and the upper mold plate 314 may be configured to be integrally molded.

Further, the cross-sectional shape of the first through-hole 3131 and the cross-sectional shape of the second through-hole 3141 are configured to correspond to the cross-sectional shape of the punch 320, and the axis of the first through-hole 3131 overlaps with the axis of the second through-hole 3141, so that the punch 320 can be completely restrained in the first through-hole 3131 and the second through-hole 3141 in other directions with respect to the blanking direction D2. And the punch 320 can cooperate with the bottom wall of the second through hole 3141 to better die cut the raw material foam 10 to form a non-adhesive foam product 20 with good product quality. The cross-sectional shape of the punch 320 may be set according to the shape of the foam product 20 to be prepared. Preferably, the punch 320 is configured in a cylindrical shape having a top plane to allow the punching to be free from sticking and to allow better punching.

Here, "cross section" means a section taken along a plane perpendicular to the punching direction D2, and "longitudinal section" means a section taken along a plane perpendicular to the conveying direction D1.

Preferably, the guide sleeve 319 is sleeved on the guide post 312 and fixed on the fixed base plate 311 through the fixed base plate 311. In this way, the fixed base plate 311 can be movably coupled to the plurality of guide posts 312 via the plurality of guide bushes 319 provided on the plurality of guide posts 312. The plurality of guide posts 312 are disposed apart from each other at a predetermined interval. It should be noted that "a plurality" herein refers to two or more, for example, in the illustrated embodiment, the guiding columns 312 are shown as four guiding columns 312. Of course, one skilled in the art may also arrange other numbers of guide posts 312 as desired.

The end of the punch 320 is fixedly disposed on one side of the fixed base plate 311 by the punch press 316. When the punch 320 is located at the initial position, the punch press plate 316 and the guide plate 313 are spaced apart by a preset distance L (see fig. 5) so that the guide plate 313 does not block the movement of the punch press plate 316 when the punch 320 moves from the initial position to the transport position. The retractable end of the die-cutting driving member 330 is fixedly disposed on the other side of the fixed substrate 311 through an adapter plate, and an end of the die-cutting driving member 330 opposite to the retractable end is fixedly disposed on the supporting platform 230. This enables the die-cutting actuator 330 to drive the fixed base 311 to move on the plurality of guide posts 312 while moving the punches 320 together. The die cut drive 330 of the present embodiment is preferably a power cylinder.

Preferably, the punch 320 includes two sub-punches 321 and a base 322 which are separated and symmetrical to each other. The end of the sub-punch 321 is fixedly disposed within the base 322. Fig. 4 and 5 show the sub-punch 321 secured to the base 322 by a fastener, although the sub-punch 321 and the base 322 may be constructed as an integral part if needed and/or desired. The base 322 is provided with a protrusion 323 protruding in a radial direction, and the fixed base plate 311 is provided with a base mounting groove 3111. When the punch press 316 is fixed to the fixed base 311, the punch press 316 and the base-mounting groove 3111 form a pocket 318, the protrusion 323 can be caught in the pocket 318, and the protrusion 323 is formed in a shape corresponding to the pocket 318. This may more securely hold the punch 320. Preferably, the base 322 is configured as a cylindrical step. The portion of the stepped portion having the larger outer diameter is retained in the pocket 318.

Further, the first through hole 3131 and the second through hole 3141 are each two through holes corresponding to the two sub punches 321. The sub-punch 321 of the present invention may be configured to have a crescent cross-sectional shape, and thus, the cross-sectional shape of the first through-hole 3131 and the cross-sectional shape of the second through-hole 3141 may also be configured to have a crescent shape, so as to punch out two symmetrical crescent-shaped foam products 20 at a time (see fig. 3).

In order to improve the punching effect of the punching mechanism 300, as shown in fig. 2 and 3, the raw material feeding mechanism 210 of the present invention includes a first belt pulling mechanism 211 and a second belt pulling mechanism 212, which are respectively disposed at two sides of the punching mechanism 300, so that the raw material foam 10 is in a flattened state. In this way, when the punch 320 punches the raw foam 10, the punching process can be made accurate and easy, and the foam product 20 is free from burrs. Meanwhile, the length of each movement of the raw material foam 10 is uniform, the punching position is uniform, the situation that the same part is repeatedly punched cannot occur, and the product quality of the foam product 20 is guaranteed.

Here, "both sides" refer to the upstream and downstream of the die-cutting mechanism 300 in the conveying direction D1 of the raw material foam 10. In other words, first and second

belt pulling mechanisms

211 and 212 are disposed along conveyance direction D1 with die cutting mechanism 300 being located intermediate the two belt pulling mechanisms. The "flattened state" refers to a state that the drawing belt mechanism applies a certain force to keep the raw material foam 10 in a tight state, but the raw material foam 10 is not subjected to stretching deformation.

Preferably, the first belt pulling mechanism 211 and the second belt pulling mechanism 212 respectively comprise

servo motors

213 and 214 and

rollers

215 and 216, and the

rollers

215 and 216 are respectively driven by the

servo motors

213 and 214 to move, and simultaneously drive the raw material foam 10. Most of the structures of the two drawtape mechanisms are substantially the same as those of drawtape mechanisms known to those skilled in the art and will not be described in detail herein.

As shown in fig. 2, the foam molding machine 200 further includes a third tape pulling mechanism, a sensor detecting device 219, and a control system for collecting the punched portion of the raw foam 10 (waste foam 30) again in a roll shape. The third belt drawing mechanism includes two

rollers

217, 218 and a member (not shown) for collecting waste foam 30 in a roll form, and the two

rollers

217, 218 are disposed adjacent to the bottom of first belt drawing mechanism 211 and the bottom of second belt drawing mechanism 212, respectively. The sensor detection device 219 is disposed at the bottom of the support platform 230 for detecting the waste foam 30 and transmitting a signal to the control system. The control system controls the third belt drawing mechanism to collect the waste foam 30 into a roll shape. For ease of understanding, fig. 2 shows an illustration of the waste foam 30 in both a relaxed state (shown in phantom) and a contracted state. It should be noted that the relaxed state and the tightened state of the waste foam alternate.

The product transfer mechanism 220 of the present invention is located above the blanking mechanism 300 and the raw material conveying mechanism 210. The product transfer mechanism 220 includes a translation mechanism 221 and a grip portion 222. The grip portion 222 is movably provided on the translation mechanism 221. When the foam product 20 is pushed to the concave portion 3142 of the upper mold 314, the grasping portion 222 moves to the upper side of the foam product 20 to grasp the foam product 20, and conveys it to the next process. Preferably, the gripping portion 222 employs pneumatic suction cups to suck the foam product 20.

According to the second aspect of the invention, the foam forming processing method is also provided and is used for punching raw foam into a plurality of separated foam products.

The foam molding processing method comprises the following steps:

s1, the foam 10 is passed through the body member 310 and moved to be flattened in the feeding direction D1, and then the feeding is suspended.

S2, the raw foam 10 is flattened and the punch 320 of the punching mechanism 300 is moved from the initial position to the pushing position in the punching direction D2 within the body member 310 to punch the raw foam 10 to form the separated foam product 20 and push the foam product 20 to move to the outside of the body member 310.

S3, the product transfer mechanism 220 transports the foam product 20 to the next process, and at the same time, the punch 320 moves from the pushing position to the initial position.

And S4, moving the raw material foam 10 to a punching position, and suspending conveying.

S5, repeating steps S2 to S4.

Step S6, the waste foam 30 formed by punching the raw material foam 10 is collected into a roll.

Specifically, the foam molding processing method comprises the following steps:

before the processing process starts, the raw material foam 10 passes through the first pulling belt mechanism 211 and then passes through the groove 3132 of the guide plate 313, then the upper template 314 and the guide plate 313 are locked by screws and are accurately positioned by the positioning pin 315, and the axes of the first through hole 3131 and the second through hole 3141 are ensured to be overlapped.

Then, the foam material 10 is moved along the conveying direction D1 (i.e. from left to right) by the first and second

belt pulling mechanisms

211 and 212, and when the foam material 10 is in the flat state, the conveying is suspended. At this time, the punch 320 of the die-cutting mechanism 300 is located within the first through-hole 3131 (i.e., in the home position). According to the performance of different raw material foams, the tension force of the belt drawing mechanism can be preset so that the raw material foams are tensioned without tensile deformation.

Next, the die-cutting driving member 330 of the die-cutting mechanism 300 drives the fixed substrate 311 to move on the plurality of guide posts 312, and simultaneously the fixed substrate 311 drives the punch 320 to move together in the die-cutting direction D2. The punch 320 moves from the initial position to the push position within the second through hole 3141 guided by the first through hole 3131. During the movement of the punch 320 in the punching direction D2, the raw foam 10 is punched by the punch 320 once to form the desired separated foam product 20 (two crescent-shaped foam products 20 are shown in the figure) and waste foam 30. The foam product 20 is pushed by the punch 320 through the second through hole 3141 to the recess 3142 of the upper die plate 314.

Subsequently, the gripper 222 of the product transfer mechanism 220 moves from the translation mechanism 221 to above the foam product 20, and sucks the foam product 20. The grasping portion 222 grasps the foam product 20 and conveys it to the next process step via the translation mechanism 221. At the same time, the punch 320 moves from the push position to the home position via the second through hole 3141 and the first through hole 3131. A die cutting process is completed.

Then, the first tape drawing mechanism 211 and the second tape drawing mechanism 212 drive the raw material foam 10 to move continuously along the conveying direction D1, and the moving lengths of the two tape drawing mechanisms are controlled by the

servo motors

213 and 214 respectively, so that the raw material foam 10 stops conveying after moving one punching position. The punching mechanism 300 continues punching and repeats the next punching process.

In the process of punching, more and more waste foam 30 are formed, and the waste foam 30 is in a loose state and gradually gathers below the punching mechanism 300 to droop due to the action of gravity. When the sensor detecting means 219 detects the waste foam 30, the third tape drawing mechanism functions to intermittently take up the waste foam 30 in a roll shape.

The foam forming processing method provided by the invention has the advantages of simple and reasonable process, good product forming effect and high matching precision among devices. Moreover, the automation level is high, the operation process can be completed without the participation of operators, the labor force is saved, and the production efficiency is improved.
