[0046] and an auxiliary driving structure arranged between the first slide plate and the second slide plate.

[0054] In a further embodiment, the first transfer mechanism further includes a holding platform disposed below the first Y-axis transfer assembly.

[0055] The first Y-axis transfer assembly is used to drive the bracket clamping assembly to move the feeding bracket on the second transfer mechanism into the plastic packaging press, or to move the feeding bracket in the plastic packaging press to the holding table.

[0056] The second transfer mechanism is used to move the feeding bracket of the holding table into the unloading device.

[0057] The beneficial effects of the present invention are: 1. The present application moves the feeding bracket on the second transferring mechanism into the plastic sealing press, and moves the feeding bracket in the plastic sealing press to the second transferring mechanism through the first transferring mechanism arranged on one side of the plastic sealing press. During the entire turnover process of the feeding bracket, only one side window of the plastic sealing press is occupied, which greatly reduces the overall occupied space of the production line and solves the problem that the production line of the prior art occupies a large space, resulting in low utilization rate of the factory building and thus increased production costs.

[0058] Moreover, it only occupies one window of the plastic sealing press, which increases the operating space of the plastic sealing press, reduces the difficulty of maintaining the plastic sealing press, and solves the problem that the existing technology occupies many windows of the plastic sealing press, resulting in great difficulty in maintaining the plastic sealing press.

[0059] Second, by arranging the unloading device below the first transfer mechanism, the height space below the first transfer mechanism can be utilized, further improving the space utilization rate of the plastic packaging system and reducing the overall occupied space of the production line.

[0060] 3. The feeding bracket is driven to rotate around the center by the second rotating component, and the discharge area without the sheets and pellets is moved to the unloading end of the third transfer mechanism, which can reduce the moving distance of the third transfer mechanism, reduce the cantilever length of the third transfer mechanism at the feeding end, and improve the accuracy and stability of the process of transferring sheets and pellets by the third transfer mechanism.

[0061] Fourth, the sheet ejection assembly and the pellet ejection rod are used to drive the sheet and the pellet to move vertically along the Z axis to move the pellet to the storage position, which can simplify the structure of the third transfer mechanism. The third transfer mechanism only needs to move and rotate along the X axis, reducing the structural complexity of the third transfer mechanism, reducing its cost, and improving its working accuracy and stability.

[0062] 5. The sheet clamping assembly realizes transmission by adopting an auxiliary driving structure between the first slide and the second slide, and the tray clamping mechanism can adopt a clamping cylinder as a driving source, thereby simplifying the structure, reducing the weight of the mechanism, and reducing the production cost of the mechanism.

[0063] 6. Through the holding table, the first transfer mechanism can first put down the feeding bracket in the plastic sealing press and grab the feeding bracket on the second transfer mechanism. While the first Y-axis transfer component drives the bracket clamping component to move the feeding bracket on the second transfer mechanism into the plastic sealing press, the second transfer mechanism moves the feeding bracket of the holding table into the unloading device, which enables the first transfer mechanism and the second transfer mechanism to work synchronously, thereby improving work efficiency.

[0094] In order to clearly express the structural layout of the present application, corresponding coordinate systems are added to the drawings to indicate the directions of various devices, mechanisms and components.

[0095] This application discloses an automated plastic packaging system, such as Figure 1-4 As shown, the structure is compact and only occupies one window of the plastic sealing press, which can reduce the overall occupied space and reduce the difficulty of maintenance work of the plastic sealing press.

[0096] First embodiment,

[0097] The automatic plastic sealing system includes: a plastic sealing press 100, a transfer device 200, a loading device 300 and a unloading device 400. Figure 1 The transfer device 200, the loading device 300 and the unloading device 400 are also provided with a sealing plate and a control panel, as shown in FIG. Figure 2 and 3 The transfer device 200 , the loading device 300 and the unloading device 400 are fixed on a frame. The unloading device 400 can be arranged on a side of the transfer device 200 away from the plastic packaging press 100 .

[0098] like Figure 4 The transfer device 200 is arranged on one side of the plastic packaging press 100 , the loading device 300 is arranged at one end of the transfer device 200 , and the unloading device 400 is arranged at the other end of the transfer device 200 .

[0099] Loading device 300,

[0100] like Figure 8 The loading device 300 shown includes: a sheet arrangement and conveying mechanism 302 and a pellet arrangement and conveying mechanism 301 arranged at one end of the transfer device 200.

[0101] exist Figure 13 In the illustrated embodiment, the material sheet arrangement and conveying mechanism 302 includes: a material box loading assembly 3021, a material sheet pushing assembly 3022 arranged at one end of the material box loading assembly 3021, a material sheet conveying assembly 3023 arranged at the other end of the material box loading assembly 3021, and a material sheet ejecting assembly 3024 arranged on both sides of the material conveying assembly 3023.

[0102] The sheet ejection assembly 3024 includes a sheet ejection power source 30241 connected to the sheet conveying assembly 3023, and a sheet ejection plate 30242 connected to the sheet ejection power source 30241. The sheet ejection plate 30242 is arranged on both sides of the sheet conveying assembly 3023, and the sheet ejection plate 30242 is located below the rubber particle clamping assembly 2033 of the third transfer mechanism 203.

[0103] like Figure 13 The material box loading assembly 3021 shown includes an electric cylinder and its mounting bracket, the sheet conveying assembly 3023 includes a conveying bracket, a conveying power source arranged below the conveying bracket, a material blocking power source connected to the conveying power source, and a blocking piece connected to the blocking power source, and the sheet ejecting assembly 3024 is arranged on both sides of the conveying bracket, the blocking power source is used to drive the blocking piece to pass through the conveying bracket and abut against the sheet, and the conveying power source is used to move the sheet to the sheet ejecting assembly in sequence, such as Figure 13The conveying power source is the conveying electric cylinder, the blocking power source can be an electric cylinder or a pneumatic cylinder, the sheet pushing component 3022 and the sheet ejecting power source 30241 are the pneumatic cylinder and its mounting bracket, such as Figure 13 The material box loading component 3021 shown moves the material box between the material sheet pushing component 3022 and the material sheet conveying component 3023 along the Z axis, and the material sheet pushing component 3022 and the material sheet conveying component 3023 move the material sheet to the material sheet ejection component 3024 in sequence along the Y axis. When the plastic pellet clamping component 2033 of the third transfer mechanism 203 moves above the material sheet ejection component 3024, the material sheet ejection component 3024 moves the material sheet to the working position of the plastic pellet clamping component 2033 of the third transfer mechanism 203 along the Z axis, and the plastic pellet clamping component 2033 of the third transfer mechanism 203 clamps the material without the third transfer mechanism 203 moving vertically along the Z axis.

[0104] like Figure 11 The shown colloid arrangement and conveying mechanism 301 includes: a vibration disk 3011, a colloid support plate 3012 arranged at the end of the vibration disk 3011, a colloid arrangement power source 3013 arranged on one side of the colloid support plate 3012, a colloid arrangement member 3014 connected to the colloid arrangement power source 3013 and arranged above the colloid support plate 3012, a colloid ejection rod 3015 arranged below the colloid support plate 3012, a colloid ejection power source 3016 connected to the colloid ejection rod 3015, a colloid auxiliary member 3017 arranged between the vibration disk 3011 and the colloid support plate 3012, and a colloid auxiliary power source 3018 connected to the colloid auxiliary member 3017.

[0105] A storage slot for storing the rubber particles is provided on one side of the rubber particle arrangement member 3014 close to the vibration plate 3011 .

[0106] like Figure 11 The colloid arrangement power source 3013 shown is an electric cylinder and its mounting bracket, the colloid ejection power source 3016 and the colloid auxiliary power source 3018 are air cylinders and their mounting brackets, and in order to avoid the moving position of the colloid arrangement component 3014, the colloid ejection power source 3016 is also set on the other side of the colloid support plate 3012, and the colloid auxiliary component 3017 is a single piece. When the colloid moves between the vibration disk 3011 and the colloid support plate 3012, the colloid auxiliary power source 3018 drives the colloid auxiliary component 3017 to push toward the colloid. Since the colloid is a cylinder, the colloid auxiliary component 3017 is against the end of the colloid away from the colloid support plate 3012, and the curved outer wall of the colloid is used to push the colloid onto the colloid support plate 3012.

[0107] like Figure 11As shown, the sheet ejection component 3024 can move the sheet in sequence to the working position of the rubber particle clamping component 2033 of the third transfer mechanism 203, and the rubber particle arrangement power source 3013 can align the vacant storage slots one by one with the discharge port of the vibration disk 3011, so that the rubber particles are arranged along the position of the storage slots. The sheet ejection component 3024 and the rubber particle ejection rod 3015 drive the sheet and the rubber particles to move vertically along the Z axis to move the rubber particles into the storage holes, which can simplify the structure of the third transfer mechanism 203. The third transfer mechanism 203 only needs to perform X-axis movement and rotation, which reduces the structural complexity of the third transfer mechanism 203, reduces its cost, and improves its working accuracy and stability.

[0111] The third transfer mechanism 203 is provided with a loading end, and the sheet arrangement and conveying mechanism 302 and the pellet arrangement and conveying mechanism 301 are provided at the loading end of the third transfer mechanism 200 .

[0112] The third transferring mechanism 203 first transfers the sheet on the sheet arrangement and conveying mechanism 302 and the granules on the granule arrangement and conveying mechanism 301 to the feeding bracket 500 of the second transferring mechanism 202, and then the second transferring mechanism 202 moves the feeding bracket 500 to the first transferring mechanism 201, and then the first transferring mechanism 201 moves the feeding bracket 500 to the molding press 100. After the molding press 100 processes the sheet on the feeding bracket 500, the first transferring mechanism 201 takes the feeding bracket 500 out of the molding press 100, and finally the second transferring mechanism 202 moves the feeding bracket 500 on the first transferring mechanism 201 to the unloading device 400.

[0118] The second rotating component 2023 is used to drive the feeding bracket 500 to rotate around the center. By driving the feeding bracket 500 to rotate around the center through the second rotating component 2023, the discharge area without containing sheets and pellets is moved to the unloading end of the third transfer mechanism 203, which can reduce the moving distance of the third transfer mechanism 203 and the cantilever length of the third transfer mechanism 203 at the feeding end, thereby improving the accuracy and stability of the process of transferring sheets and pellets by the third transfer mechanism 203.

[0146] Automatic loading and unloading method:

[0147] The material box loading component 3021 first moves the material box containing the material sheets between the material sheet pushing component 3022 and the material sheet conveying component 3023, and then the material sheet pushing component 3022 moves the material sheets in the material box to the material conveying component 3023 in sequence, and then the material conveying component 3023 moves the material sheets to the material ejecting component 3024 in sequence, and then the material ejecting component 3024 moves the material on the material conveying component 3023 to the working position of the rubber particle clamping component 2033 of the third transfer mechanism 203.

[0148] The vibration plate 3011 first moves the rubber particles in sequence to the position between the vibration plate 3011 and the rubber particle support plate 3012, and then the rubber particle auxiliary power source 3018 drives the rubber particle auxiliary component 3017 to move the rubber particles between the vibration plate 3011 and the rubber particle arrangement component 3014 to the storage slot, and then the rubber particle arrangement power source 3013 drives the rubber particle arrangement component 3014 to move in sequence. When the rubber particle arrangement component 3014 moves to the position as shown in FIG. Figure 11 When in the predetermined position shown, the storage slot, the storage hole and the rubber particle ejection rod 3015 cooperate concentrically. At this time, the rubber particle ejection power source 3016 drives the rubber particle ejection rod 3015 to move the rubber particles in the storage slot to the storage hole. The rubber particle clamping cylinder 20332 then drives the rubber particle baffle 20333 to confine the rubber particles in the storage hole.

[0149] The third X-axis transfer component 2031 of the third transfer mechanism 203 first moves the sheet and the rubber particles from the sheet arrangement and conveying mechanism 302 and the rubber particle arrangement and conveying mechanism 301 to the second transfer mechanism 202. At the same time, after a sheet clamping component 600 clamps a sheet, the third rotating component 2032 drives the two sheet clamping components 600 to rotate, and then makes the other sheet clamping component 600 clamp another sheet to make the two sheets symmetrical. Then the third rotating component 2032 adjusts the angle of the sheet clamping component 600 and the rubber particle clamping component 2033 according to the angle of the discharge area of the feeding bracket 500 on the second transfer mechanism 202, and then places the sheet and rubber particles in the discharge area of the feeding bracket 500.

[0150] After the third transfer mechanism 203 places the sheet and the granules into a discharge area of the feeding bracket 500, the second rotating component 2023 drives the feeding bracket 500 to rotate around the center by a predetermined angle, so that a discharge area of the feeding bracket 500 that does not contain sheet and granules is transferred to the bottom of the third transfer mechanism 203, and at the same time, the third rotating component 2032 adjusts the angle of the sheet clamping component 600 and the granule clamping component 2033 according to the angle of the discharge area of the feeding bracket 500. When all the discharge areas of the feeding bracket 500 are filled with sheet and granules, the second transfer mechanism 202 moves the feeding bracket 500 to the first transfer mechanism 201.

[0151] Then the first transfer mechanism 201 moves the feeding support 500 into the plastic packaging press 100 . After the plastic packaging press 100 processes the sheet on the feeding support 500 , the first transfer mechanism 201 takes the feeding support 500 out of the plastic packaging press 100 .

[0152] Finally, the second transfer mechanism 202 moves the feeding support 500 containing the processed tablets on the first transfer mechanism 201 into the unloading device 400 .

[0153] The second transfer mechanism 202 moves the feeding bracket 500 to the bottom of the unloading transfer mechanism 401, and then the unloading transfer mechanism 401 drives the first unloading clamping mechanism 402 to place the material on the second transfer mechanism 202 on the working area of the cutting mechanism 403, and then the cutting mechanism 403 cuts the material, and then the unloading transfer mechanism 401 drives the second unloading clamping mechanism 404 to move the material in the working area of the cutting mechanism 403 to the finished product box 405. After the second unloading clamping mechanism 404 moves the material on the cutting mechanism 403 to the finished product box 405, the second unloading rotating assembly 4041 is used to drive the material clamping assembly 600 to rotate so that the angle of the material matches the finished box 405, and then the second unloading clamping mechanism 404 places the material in the working area of the cutting mechanism 403 into the finished product box 405.

[0154] Among them, the first unloading clamping mechanism 402 clamps the material on the feeding bracket 500. After the material in a discharge area of the feeding bracket 500 is taken out, the unloading X-axis transfer component 4021 continues to move the position of the material clamping component 600 to the next discharge area of the feeding bracket 500, so that the first unloading clamping mechanism 402 continues to clamp the material. When the second transfer mechanism 202 rotates the feeding bracket 500 to move the next discharge area of the feeding bracket 500 to the bottom of the first unloading clamping mechanism 402, after the first unloading clamping mechanism 402 clamps the material, the first unloading rotating component 4022 drives the material clamping component 600 to rotate, so that the angle or direction of the material cooperates with the cutting mechanism 403.

[0155] The second embodiment is different from the first embodiment in that the unloading device 400 is located on a side of the transfer device 200 close to the plastic packaging press 100 .

[0156] The unloading device 400 is located below the first transfer mechanism 201 .

[0157] By arranging the unloading device 400 below the first transfer mechanism 201 , the height space below the first transfer mechanism 201 can be utilized, thereby further improving the space utilization rate of the plastic packaging system and reducing the overall occupied space of the production line.

[0158] The third embodiment, based on the first and / or second embodiment, provides a placing table connected to the frame.

[0159] like Figure 19 As shown, the first transfer mechanism 201 further includes a placing platform arranged below the first Y-axis transfer component 2011.

[0160] The first Y-axis transfer assembly 2011 is used to drive the bracket clamping assembly 2013 to move the feeding bracket 500 on the second transfer mechanism 202 into the plastic packaging press 100, or to move the feeding bracket 500 in the plastic packaging press 100 to the placing table.

[0161] The second transfer mechanism 202 is used to move the feeding bracket 500 of the placing table into the unloading device 400 .

[0162] In this embodiment, the holding table is hollow, and both sides of the holding table are against the feeding bracket 500 to support the feeding bracket 500. After the second transfer mechanism 202 moves to the bottom of the holding table, it moves vertically upward along the Z axis to take out the feeding bracket 500 on the holding table.

[0163] Through the holding table, the first transfer mechanism 201 can first put down the feeding bracket 500 in the plastic sealing press 100 and grab the feeding bracket 500 on the second transfer mechanism 202. While the first Y-axis transfer component 2011 drives the bracket clamping component 2013 to move the feeding bracket 500 on the second transfer mechanism 202 into the plastic sealing press 100, the second transfer mechanism 202 moves the feeding bracket 500 of the holding table into the unloading device 400, which enables the first transfer mechanism 201 and the second transfer mechanism 202 to work synchronously, thereby improving work efficiency.

[0164] In the above embodiments, connecting members such as mounting plates are provided between structures or parts that are connected across a certain distance to achieve the connection between the structures or parts.

[0165] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself.
