Description

Technical Field

[0001] The invention relates to the field of rubber recycling, and in particular to a rubber recycling injection molding device and a molding process. Background Art

[0002] Waste rubber products place a great burden on the environment. However, by recycling rubber, we can transform it into a useful resource and reduce waste and environmental pollution.

[0003] The process of recycling rubber includes several steps: first, the rubber products are collected, sorted and processed to remove impurities; next, the rubber products are peeled, crushed or cut into small pieces to make them easier to handle in the next step; then, the rubber is specially processed and treated to make it a usable raw material again; finally, this recycled rubber can be used to make new rubber products, such as making rubber shoes.

[0004] One of the rubber products currently recycled: double-sided patch rubber sheet is composed of two layers of cotton cloth and rubber sheet. The two layers of cotton cloth are wrapped on the upper and lower sides of the rubber sheet by rubber adhesive, thereby enhancing the overall strength of the rubber sheet. When recycling double-sided patch rubber sheet, the cotton cloth needs to be peeled off from the double-sided patch rubber sheet first, and before peeling, the double-sided patch rubber sheet needs to be soaked in a solvent that can soften the rubber adhesive to soften the rubber adhesive, and then the cotton cloth and the double-sided patch rubber sheet are separated.

[0005] However, when the existing double-sided patch rubber sheet is separated from the cotton cloth, part of the rubber adhesive is not completely softened, which causes the cotton cloth to tear during the peeling process, resulting in part of the cotton cloth still attached to the rubber sheet, making the separation effect of the cotton cloth and the double-sided patch rubber sheet poor. At the same time, after the cotton cloth is separated from the double-sided patch rubber sheet, the cotton cloth itself is water-absorbent, so that the solvent is retained on the cotton cloth, causing a waste of resources. Summary of the invention

[0006] In order to overcome the shortcomings of the existing double-sided cloth-applied rubber sheet, that is, when being separated from the cotton cloth, part of the rubber adhesive is not completely softened, resulting in part of the cotton cloth still being attached to the rubber sheet, and the solvent is retained on the cotton cloth, causing a waste of resources, the present invention provides a rubber recycling injection molding device and a molding process.

DETAILED DESCRIPTION

[0037] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0038] Example 1

[0039] A rubber recycling injection molding device, such as Figure 1-Figure 6 As shown, it includes a dissolving tank 1 and a placement plate 2; the dissolving tank 1 contains a solvent; the placement plate 2 is arranged in the dissolving tank 1, and the placement plate 2 is located above the solvent liquid surface;

[0040] It also includes a fixed plate 101, a driving component, a fixed block 3, a friction rod 4 and an auxiliary component; a connecting component is installed in the dissolving tank 1; a driving component is installed in the dissolving tank 1; two left-right symmetrical fixed plates 101 are fixedly connected to the placement plate 2; each fixed plate 101 is movably connected to a fixed block 3 through an elastic telescopic rod; three friction rods 4 are installed on the moving part of the driving component, and the friction rods 4 are driven to move left and right through the moving part of the driving component; a number of serrated protrusions are arranged on the lower side of each friction rod 4; an auxiliary component is installed in the dissolving tank 1, and the residual solvent on the cloth is squeezed out by the auxiliary component, thereby reducing resource waste.

[0041] Furthermore, in order to reduce the damage to the double-sided cloth-patterned rubber plate 5 , each fixing block 3 is configured to be in a pointed cone shape on one side close to the friction rod 4 .

[0042] It also includes a driving member 105; three driving members 105 are fixedly connected to the moving part of the driving component, and the driving member 105 is an electric push rod. The moving part of the driving component is connected to the corresponding friction rod 4 through the driving member 105; each friction rod 4 is rotationally connected to the output end of the driving member 105 through a torsion spring; a curved hook 4001 is provided on the lower side of each friction rod 4.

[0043] The driving assembly includes a connecting plate 102, a slide rail 103 and an electric slider 104; two front-to-back symmetrical slide rails 103 are fixedly connected to the inner wall of the dissolution tank 1; an electric slider 104 is slidably connected to each slide rail 103; a connecting plate 102 is fixedly connected between the two electric sliders 104; and the connecting plate 102 is connected to the driving member 105.

[0044] The working steps of this embodiment are:

[0045] In the first step, a proper amount of double-sided patch rubber sheet 5 is placed into the dissolution tank 1, and soaked for a corresponding time according to the properties of the double-sided patch rubber sheet 5 and the thickness of the rubber adhesive. The soaked double-sided patch rubber sheet 5 is then placed on the placement plate 2, and then the pointed cone parts of the two fixing blocks 3 are respectively inserted into the front and rear sides of the right end of the double-sided patch rubber sheet 5, so as to fix the double-sided patch rubber sheet 5.

[0046] In the second step, the electric slider 104 is controlled to move rightward on the slide rail 103, and the connecting plate 102, the driving member 105 and the friction rod 4 are driven to move rightward until the friction rod 4 is close to the right end of the double-sided patch rubber plate 5. At this time, the driving member 105 is controlled to extend downward, so that the friction rod 4 gradually approaches the double-sided patch rubber plate 5. Since the friction rod 4 is rotationally connected to the output end of the driving member 105 through a torsion spring, the friction rod 4 is squeezed by the double-sided patch rubber plate 5 and then rotates upward. At this time, the serrated protrusion on the friction rod 4 is in close contact with the cloth.

[0047] In the third step, since the double-sided patch rubber sheet 5 has been soaked in the solvent, most of the rubber adhesive between the double-sided patch rubber sheet 5 and the cloth has been softened. When the serrated protrusion on the friction rod 4 is in close contact with the cloth, the electric slider 104 is controlled to drive the friction rod 4 to move leftward, so that the serrated protrusion on the friction rod 4 drives the upper layer of cloth of the double-sided patch rubber sheet 5 on the placement plate 2 to be squeezed and rubbed along the surface of the double-sided patch rubber sheet 5 from the right end to the left end, thereby realizing the separation between the upper layer of cloth of the double-sided patch rubber sheet 5 and the double-sided patch rubber sheet 5.

[0048] In the third step: when the serrated protrusion on the friction rod 4 is in close contact with the cloth, the electric slider 104 is controlled to drive the friction rod 4 to move to the left a suitable distance, and the driving member 105 is controlled to drive the friction rod 4 to move upward. At this time, the friction rod 4 rebounds and resets through the action of the torsion spring and is in a vertical state. At the same time, when the friction rod 4 rebounds and resets, the hook 4001 on the friction rod 4 will be inserted into the rubbed cloth, so that the right end of the cloth is lifted upward, and then the electric slider 104 is controlled to drive the friction rod 4 to move to the left, so that the separated cloth is separated from the double-sided patch rubber plate 5, thereby improving the separation effect of the cloth and the double-sided patch rubber plate 5.

[0049] In the fourth step, after the upper layer of the double-sided patch rubber plate 5 is separated, the cloth on the friction rod 4 is manually removed, and then the double-sided patch rubber plate 5 is turned over and fixed again, and the above steps are repeated to separate the lower layer of the double-sided patch rubber plate 5 from the double-sided patch rubber plate 5; the rubber adhesive between the cloth and the double-sided patch rubber plate 5 is softened by a solvent, and the friction rod 4 is moved to drag and tear the cloth on the double-sided patch rubber plate 5, so as to separate the cloth from the double-sided patch rubber plate 5, thereby protecting the rubber integrity of the double-sided patch rubber plate 5 to the greatest extent and avoiding waste of resources.

[0050] In the fifth step, the recycled rubber is crushed, separated and dried to make recycled rubber particles. After mixing, it is put into an injection molding machine to make semi-finished rubber shoes for plasticization, injection, pressure holding and vulcanization. After vulcanization, the mold is opened after cooling, and then the finished rubber shoes are taken out.

[0051] Example 2

[0052] On the basis of Example 1, Figure 1 , Figure 2 and Figure 7 As shown, the auxiliary component includes a connecting rod 201 and a squeezing roller 202; each fixed plate 101 is provided with a first limiting groove 10101 on the side close to the friction rod 4, and a connecting rod 201 is slidably connected between two adjacent first limiting grooves 10101; the friction force between the connecting rod 201 and the first limiting groove 10101 is large; and a squeezing roller 202 is fixedly connected to the connecting rod 201.

[0053] The auxiliary components also include a connecting block 203, a liquid outlet pipe 204 and a connecting pipe 205; two front-to-back symmetrical connecting blocks 203 are fixedly connected to the connecting rod 201; a liquid outlet pipe 204 is commonly fixedly connected between the two connecting blocks 203; three nozzles 20401 are arranged on the liquid outlet pipe 204; a second limiting groove 10102 is arranged on the upper side of each fixed plate 101, and the liquid outlet pipe 204 slides left and right in the adjacent second limiting groove 10102; the rear end of the liquid outlet pipe 204 is connected with a connecting pipe 205, and the connecting pipe 205 is externally connected to a water pump; the connecting pipe 205 is a telescopic hose, and the connecting pipe 205 is connected to the dissolution tank 1, and an interception net is arranged at the connection between the connecting pipe 205 and the dissolution tank 1.

[0054] The working principle of this embodiment is:

[0055] In the first step of Example 1: after the soaked double-sided patch rubber sheet 5 is fixed on the placement plate 2, the connecting rod 201 is manually pushed to the right, so that the connecting rod 201 slides to the right in the first limiting groove 10101, and drives the liquid outlet pipe 204 to slide to the right in the second limiting groove 10102, until the fixed block 3 is located between the connecting rod 201 and the liquid outlet pipe 204, then the electric slider 104 is controlled to drive the friction rod 4 to move between the connecting rod 201 and the liquid outlet pipe 204, and then the driving member 105 is controlled to drive the friction rod 4 to move up and down, when the friction rod 4 is wrapped around the fabric of the double-sided patch rubber sheet 5 and is pulled out from the connecting rod 201 and the liquid outlet pipe 204 rises upward, and then moves to the left to pull the fabric. At this time, an angle is formed between the right end fabric separated from the double-sided patch rubber plate 5 and the fabric attached to the surface of the double-sided patch rubber plate 5, and the formed angle wraps the squeezing roller 202. At the same time, the angle formed by the fabric will move to the left along with the friction rod 4, so that the fabric moves to the left with the squeezing roller 202. Since the friction between the connecting rod 201 and the first limiting groove 10101 is large, the squeezing roller 202 will squeeze the fabric separated from the double-sided patch rubber plate 5, thereby squeezing the residual solvent inside the fabric to reduce resource waste.

[0056] When the cloth wraps around the squeezing roller 202 and drives it to move to the left, the squeezing roller 202 will drive the liquid outlet pipe 204 to move to the left together. At this time, the external water pump is started to extract the solvent inside the dissolving tank 1 and spray it out from the nozzle 20401 of the liquid outlet pipe 204. The solvent is continuously sprayed toward the separation part of the cloth and the double-sided patch rubber plate 5, thereby impacting the separation part, which not only enhances the separation effect of the cloth and the double-sided patch rubber plate 5, but also makes the solvent wet the rubber adhesive on the double-sided patch rubber plate 5 again, preventing the rubber adhesive in some parts of the double-sided patch rubber plate 5 from being not completely softened, thereby improving the separation efficiency of the cloth and the double-sided patch rubber plate 5.

[0057] Example 3

[0058] On the basis of Example 1-2, Figure 1 , Figure 2 and Figure 8 As shown, a filter screen 301 is also included; the placement plate 2 is arranged to be inclined downward; the filter screen 301 is fixedly connected to the dissolving tank 1, and the connection point between the connecting pipe 205 and the dissolving tank 1 and the filter screen 301 are respectively located on the left and right sides of the dissolving tank 1.

[0059] Furthermore, in order to prevent the sand impurities at the bottom of the dissolution tank 1 from flowing with the solvent and causing the solvent to become turbid, a block 30101 for intercepting the deposited particles is provided on the lower side of the filter 301 .

[0060] It also includes a guide sheet 302; two guide sheets 302 are fixedly connected to the dissolution tank 1 and are staggered in an upper and lower manner; each guide sheet 302 is made of a deformable material, and the upper surface of each guide sheet 302 is set to a rough surface; each guide sheet 302 is set with a plurality of through holes 30201.

[0061] Furthermore, in order to reduce the number of times the solvent needs to be replaced and to recycle the solvent, a storage basket 303 for collecting impurities is slidably connected to the bottom of the dissolution tank 1 .

[0062] The working principle of this embodiment is:

[0063] In Example 2: When the nozzle 20401 of the liquid outlet pipe 204 flushes the cloth and the double-sided patch rubber sheet 5, the placement plate 2 is arranged to be inclined downward, so that the impurities flushed from the double-sided patch rubber sheet 5 slide along the placement plate 2 into the dissolution tank 1, thereby preventing the impurities from being retained on the placement plate 2 and causing accumulation, affecting the subsequent fixing effect of the double-sided patch rubber sheet 5, and at the same time reducing the number of manual cleaning times and alleviating the manual workload.

[0064] When the solvent carries impurities and flows downward from the placement plate 2, since the upper surface of the guide sheet 302 is set as a rough surface, when the solvent carries impurities and passes through the guide sheet 302, the friction of the guide sheet 302 is increased by the rough surface of the guide sheet 302, and at the same time, the guide sheet 302 that is staggered up and down blocks the impurities multiple times, thereby slowing down the movement speed of the impurities, causing most of the impurities to slowly fall along the curved surface of the guide sheet 302 and gather on the right side of the dissolution tank 1, thereby preventing the impurities from rushing into the water with the solvent and moving around with the turbulence, causing the solvent to be too turbid and reducing its performance.

[0065] At the same time, the large impurities flushed down are intercepted by the filter 301, and the sand impurities deposited at the bottom of the dissolution tank 1 are blocked by the block 30101, so as to prevent the sand impurities at the bottom of the dissolution tank 1 from flowing with the solvent when the water pump is started, causing the solvent to become turbid and affecting the softening effect of the solvent on the rubber adhesive.

[0066] The impurities gathered on the right side of the dissolution tank 1 will gradually settle inside the storage basket 303. When the impurities in the storage basket 303 accumulate to a certain amount, the storage basket 303 is manually lifted up and the impurities inside are processed. After the processing, it is put back to its original position. The deposited impurity sand is uniformly collected and processed by the storage basket 303, thereby extending the use time of the solvent inside the dissolution tank 1, reducing the number of times the solvent is replaced, and the solvent is recycled to reduce resource waste.

[0067] A rubber recycling injection molding process includes the following working steps:

[0068] S1: separation, controlling the friction rod 4 to rub the soaked double-sided patch rubber plate 5 to separate the fabric from the double-sided patch rubber plate 5;

[0069] S2: squeezing and flushing, controlling the squeezing roller 202 to squeeze the fabric to squeeze out the residual solvent on the fabric, and controlling the liquid outlet pipe 204 to impact the separation part between the fabric and the double-sided fabric-applied rubber sheet to enhance the separation effect;
