Description

Technical Field

[0001] The invention relates to the technical field of cap processing devices, and in particular to a bottle cap unloading system. Background Art

[0002] Bottles are common containers for liquid products. In order to ensure the safety of the items in the bottle, prevent the items from tipping over and leaking during transportation and storage, and improve the sealing performance of the bottle, it is usually necessary to install bottle caps on the bottle. Bottle caps can be divided into wood, metal, and plastic according to their materials. Plastic bottle caps are widely used due to their low cost, simple processing, and easy molding. When producing plastic bottle caps, PP or PE raw materials are usually processed and molded by injection molding or compression molding.

[0003] For example, the patent document with the publication number CN117067521A discloses a wine bottle cap production device, including a male mold seat and a female mold seat, a bottle cap female mold slidably arranged in the female mold seat, a casting hole and a mounting hole interconnected are arranged in sequence in the bottle cap female mold, a crimping sleeve is tightly arranged in the mounting hole, and one end of the crimping sleeve is fixed on the inner wall of the mounting hole; a spring is arranged between the bottle cap female mold and the mounting hole; a variable diameter through hole with small ends and large middle is arranged in the crimping sleeve, and a drainage hole connected to the variable diameter through hole is arranged at the bottom end of the crimping sleeve; a blocking mechanism is arranged at the end of the bottle cap female mold, and the blocking mechanism extends into the variable diameter through hole to block the small diameter hole of the variable diameter through hole. When the crimping sleeve extends out of the mounting hole and is crimped with the bottle cap male mold, the flow channel is heated by ventilation heating, passing high-temperature plastic liquid, etc. to melt the solidified plastic in the flow channel and discharge it, so as to ensure the quality of the cast product.

[0004] Although the above technical scheme can improve the production quality of bottle caps, after the bottle caps are injection molded, the molded cap body needs to be demolded from the mold so that the mold can continue to injection mold the bottle caps. In the prior art, when the bottle caps are demolded and unloaded, the molded bottle caps are usually dropped downward under the action of gravity and output from the receiving port below the mold. As a result, after the bottle caps fall, they are easily contaminated with stains such as lubricating oil dripping downward from the production device, resulting in contamination of the bottle caps, resulting in the bottle caps for food failing to meet food hygiene requirements; and in the production process of some bottle caps, a material head is usually reserved on the cap body. In the prior art, after the bottle caps are produced, a separate process is required to clean the material head on the bottle caps, resulting in an increase in the production process steps of the bottle caps and a reduction in the production efficiency of the bottle caps. Summary of the invention

[0005] The present invention is intended to provide a bottle cap unloading system to solve the technical problem in the prior art that the bottle caps are easily contaminated after unloading.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a bottle cap unloading system, comprising a production unit and a unloading unit, the production unit comprising a first mold and a second mold distributed opposite to each other, the first mold and the second mold are used for producing and processing bottle caps; the unloading unit comprises a grabbing part and a fixed frame, the fixed frame is located above the production unit, the fixed frame spans across both sides of the production unit, the extension direction of the fixed frame is perpendicular to the extension direction of the first mold and the second mold, the grabbing part can move along the extension direction of the fixed frame, the grabbing part is used to grab the bottle caps produced by the production unit; the fixed frame is provided with a dividing rod on the side away from the production unit, and the dividing rod is used to remove the bottle cap material heads grabbed by the grabbing part.

[0007] The principles and advantages of this solution are as follows: when unloading the bottle caps produced by the production unit, the gripping part moves along the fixed frame to one side of the mold of the production unit, and clamps the bottle caps formed on the mold through the gripping part. The bottle caps are driven by the gripping part to move on the fixed frame in a direction away from the production unit. When the fixed frame moves to one side of the dividing rod, the bottle caps are moved on one side of the dividing rod, so that the material heads on the bottle caps are broken and separated from the bottle caps under the blocking action of the dividing rod; after the gripping part places the bottle caps with the material heads separated at the corresponding position, the unloading operation of the bottle caps is completed.

[0008] Compared with the prior art, in this solution, when unloading the bottle caps, the formed bottle caps are grabbed by the fixed plate and transferred to the conveyor belt on one side of the production unit, so that the bottle caps can be transferred to a position far away from the injection mold in the production unit for transportation during unloading, avoiding the bottle caps from directly falling and contacting with the oil stains falling from the mold during the unloading process, causing the bottle caps to be contaminated and affecting the quality of the bottle caps. In addition, when unloading the bottle caps, by setting a dividing rod during the movement of the bottle caps to the conveyor belt, the material heads on the bottle caps can be removed during the process of being transferred to the conveyor belt, avoiding the need to remove the material heads of the bottle caps separately after the bottle caps are unloaded, increasing the steps of the bottle cap production and processing, and reducing the efficiency of the bottle cap production and processing.

[0009] Preferably, as an improvement, the gripping part includes a first telescopic rod, one end of which is slidably connected to the fixing frame, and the other end of which extends outwardly in a direction perpendicular to the extension direction of the fixing frame. The gripping part can be moved in a horizontal direction driven by the first telescopic rod, and when gripping the bottle caps, the gripping part can be moved in a direction close to or away from the first mold or the second mold in the production unit driven by the first telescopic rod, so that the gripping part can accurately align and grip the bottle caps in the production unit, thereby improving the accuracy of the bottle cap gripping and unloading operations. The flexibility of the gripping part in gripping and transferring the bottle caps is improved.

[0010] Preferably, as an improvement, the end of the first telescopic rod away from the fixed frame is connected to a second telescopic rod; the end of the second telescopic rod away from the first telescopic rod extends downward in the height direction, and the end of the second telescopic rod away from the first telescopic rod is provided with a fixing plate, and the second telescopic rod is used to drive the fixing plate to move up and down in the height direction. The second telescopic rod drives the grasping part to move up and down in the height direction, thereby improving the flexibility of the grasping part in grasping and transporting the bottle cap.

[0011] Preferably, as an improvement, the fixing plate is rotatably connected to the end of the second telescopic rod away from the first telescopic rod, so that the fixing plate can rotate on the second telescopic rod when grabbing and unloading the bottle caps, so that the angle of the fixing plate can be adjusted according to actual needs during grabbing and unloading, thereby improving the flexibility of the fixing plate in unloading.

[0012] Preferably, as an improvement, the fixing plate is provided with a plurality of clamping members, which are evenly distributed on the fixing plate, and the clamping members are used to clamp the bottle caps, so that when the bottle caps are unloaded, each bottle cap can be stably clamped and fixed, ensuring the stability of the bottle caps in the gripping part, and preventing the bottle caps from falling during the unloading process, which affects the normal unloading of the bottle caps.

[0013] Preferably, as an improvement, the unloading unit is also used to screen the quality of the bottle caps on each clamping member. The unloading unit screens the bottle caps with processing defects during the unloading process, so that the defective bottle caps can be separated in time, avoiding the mixing of defective bottle caps and normal bottle caps in transportation, increasing the screening steps for subsequent processing of the bottle caps, and affecting the processing efficiency of the bottle caps.

[0014] Preferably, as an improvement, a recycling slot is provided on one side of the fixing frame away from the production unit, and the recycling slot is used to recycle the bottle caps screened by the unloading unit. By recycling and reusing defective bottle caps, waste in the bottle cap production process is reduced and resource utilization is improved.

[0015] Preferably, as an improvement, a collecting trough is provided below the material dividing rod, and the collecting trough is used to collect the material heads separated by the material dividing rod, so that the material heads separated by the material dividing rod can fall into the collecting trough for collection, which is convenient for recycling and reusing the material heads, reducing resource waste and preventing the separated material heads from falling everywhere and affecting the cleanliness of the processing environment.

[0020] As attached Figure 1 As shown, a bottle cap unloading system includes a production unit 1 and a unloading unit 2, wherein the production unit 1 is used for injection molding of bottle caps, and the unloading unit 2 is used for unloading the bottle caps produced by injection molding in the production unit 1.

[0021] The production unit 1 includes a frame 101, on which a first mold 102 and a second mold 103 are arranged facing each other, and the first mold 102 and the second mold 103 are arranged opposite to each other in the horizontal direction. The first mold 102 and the second mold 103 can move toward or away from each other in the horizontal direction, and the first mold 102 and the second mold 103 are slidably connected to the frame 101 through a slide rail, and the first mold 102 and the second mold 103 are used for injection molding of the cover body, wherein the first mold 102 and the second mold 103 can be injection molding structures in an injection molding machine, and the specific structures of the first mold 102 and the second mold 103 are prior art and will not be described in detail here.

[0022] The unloading unit 2 includes a grabbing portion 202 and a fixed frame 201, wherein the fixed frame 201 is located on one side of the production unit 1, the fixed frame 201 is located above the production unit 1, and the fixed frame 201 spans across both sides of the production unit 1, and specifically, one end of the fixed frame 201 is fixedly connected to the ground on one side of the production unit 1, and the other end extends outward in a direction perpendicular to the moving direction of the first mold 102 or the second mold 103 in the production unit 1, the grabbing portion 202 is slidably connected to the top of the fixed frame 201, and the grabbing portion 202 can move along the extension direction of the fixed frame 201, wherein the grabbing portion 202 and the fixed frame 201 can be connected by structures such as rollers or screws, wherein the specific structure of the sliding connection between the grabbing portion 202 and the fixed frame 201 is prior art and will not be repeated here. After grabbing the bottle cap, the grabbing part 202 can move along the extension direction of the fixing frame 201 away from the production unit 1, so that the unloaded bottle cap can quickly move away from the production unit 1, avoiding the bottle cap from falling under the production unit 1 during the unloading process and causing the bottle cap to be contaminated, while ensuring that the production unit 1 can carry out the next injection molding process in time.

[0023] The grabbing part 202 includes a first telescopic rod 203, one end of which is slidably connected to the fixing frame 201, and the other end of the first telescopic rod 203 extends in a direction perpendicular to the extension direction of the fixing frame 201 toward the production unit 1. A second telescopic rod 204 is fixedly connected to one end of the first telescopic rod 203 away from the fixing frame 201 by bolts, and the first telescopic rod 203 is used to drive the second telescopic rod 204 to move in a direction close to or away from the fixing frame 201. The grabbing part 202 can move in a horizontal direction driven by the first telescopic rod 203, so that when the grabbing part 202 grabs the bottle cap, it can move in a direction close to or away from the first mold 102 or the second mold 103 in the production unit 1 under the drive of the first telescopic rod 203, so that the grabbing part 202 can accurately align and grab the bottle cap in the production unit 1, thereby improving the accuracy of the bottle cap grabbing and unloading operation. The flexibility of the grabbing part 202 in grabbing and transferring the bottle cap is improved.

[0024] The end of the second telescopic rod 204 away from the first telescopic rod 203 extends downward in the height direction, and a fixing plate 205 is provided at the end of the second telescopic rod 204 away from the first telescopic rod 203. The second telescopic rod 204 is used to drive the fixing plate 205 to move up and down in the height direction. The first telescopic rod 203 and the second telescopic rod 204 can be telescopic structures such as electric telescopic rods or telescopic hydraulic rods, and the specific structures of the first telescopic rod 203 and the second telescopic rod 204 are prior art and will not be described in detail here. The second telescopic rod 204 drives the grasping part 202 to move up and down in the height direction, thereby improving the flexibility of the grasping part 202 in grasping and transporting the bottle caps.

[0025] The middle part of one side of the fixed plate 205 is rotatably connected to the end of the second telescopic rod 204 away from the first telescopic rod 203 through a rotating shaft, and the fixed plate 205 can rotate along the central axis of the rotating shaft, wherein the specific content of the fixed plate 205 rotating on the second telescopic rod 204 is the prior art and will not be repeated here. When the fixed plate 205 grabs and unloads the bottle caps, it can rotate on the second telescopic rod 204, so that the angle of the fixed plate 205 can be adjusted according to actual needs during grabbing and unloading, thereby improving the flexibility of the fixed plate 205 in unloading.

[0026] As attached Figure 2As shown, a plurality of clamping members 206 are fixedly connected by bolts on one side of the fixing plate 205 away from the second telescopic rod 204, and the plurality of clamping members 206 are evenly distributed on the fixing plate 205, and the clamping members 206 are used to clamp and discharge the bottle caps produced by the production unit 1. The clamping members 206 may be structures such as clamping claws and suction cups. Preferably, in this embodiment, the clamping members 206 use clamping claws to grab and discharge the bottle caps, and the specific content of grabbing the bottle caps by the clamping claws is the prior art, which will not be described in detail here. In other embodiments, other types of clamping members 206 may also be used to grab and discharge the bottle caps.

[0027] A conveyor belt 3 is provided at one end of the fixed frame 201 away from the production unit 1, one end of the conveyor belt 3 is located below the fixed frame 201, and the other end of the conveyor belt 3 extends outward in a direction perpendicular to the fixed frame 201. The conveyor belt 3 is used to convey the bottle caps grabbed by the fixed plate 205 on the fixed frame 201. The specific structure of the conveyor belt 3 is prior art and will not be described in detail here.

[0028] A dividing rod 4 is provided on the side of the conveyor belt 3 close to the production unit 1. The dividing rod 4 is fixedly connected to one side of the conveyor belt 3 through a supporting rod. The dividing rod 4 is used to remove the material heads on the unloaded bottle caps. Specifically, after the clamping member 206 on the fixed plate 205 grabs the bottle caps produced in the production unit 1, the fixed plate 205 moves toward the conveyor belt 3 along the fixed frame 201 driven by the first telescopic rod 203 and the second telescopic rod 204. When the fixed plate 205 passes through the dividing rod 4, the first telescopic rod 203 and the second telescopic rod 204 drive the fixed plate 205 to move back and forth along the height direction on one side of the dividing rod 4, so that the material heads of the bottle caps on the fixed plate 205 are broken under the obstruction of the dividing rod 4, thereby achieving the removal of the material heads on the bottle caps.

[0029] A collecting trough 401 is provided below the material dividing rod 4, and the collecting trough 401 is used to collect the material heads separated by the material dividing rod 4. The material heads separated by the material dividing rod 4 can fall into the collecting trough 401 for collection, which is convenient for recycling the material heads, reducing resource waste and preventing the separated material heads from falling everywhere and affecting the cleanliness of the processing environment.

[0030] A partition plate 402 is provided on the side of the collecting trough 401 close to the conveyor belt 3; one end of the partition plate 402 is fixedly connected to the collecting trough 401 by welding or bolts, and the other end extends upward in the height direction, and the end of the partition plate 402 away from the collecting trough 401 is inclined toward the conveyor belt 3. When the material heads removed by the material dividing rod 4 fall downward to the collecting trough 401, the material heads can slide into the collecting trough 401 under the guidance of the partition plate 401, so as to avoid the material heads from splashing outwards due to the tilting when breaking during the falling process, resulting in the material heads still splashing onto the conveyor belt 3 after being removed, causing the separated material heads to mix with the bottle caps again, affecting the separation effect of the bottle caps and the material heads.

[0031] The unloading unit 2 is also used to screen the bottle caps produced by the production unit 1, that is, when the unloading unit 2 unloads the bottle caps, the quality of the bottle caps grabbed on the fixed plate 205 is screened, and the bottle caps that meet the quality requirements are placed on the conveyor belt 3 and transported to the next processing step; the specific clamps 206 on the fixed plate 205 can be opened and closed independently of each other. When the quality of the bottle caps is screened, it can be judged by obtaining whether there is an abnormality in the assembly and fixation of the mold when the production unit 1 produces the bottle caps. When the production unit 1 is processing the bottle caps, when there is an assembly displacement of the fixed structure in the mold, it is judged that the bottle caps produced by the fixed structure are abnormal. The specific content of the independent control of each clamp 206 and the quality detection of the bottle caps by the production unit 1 is the prior art, which will not be repeated here. The unloading unit 2 screens the bottle caps with processing defects during the unloading process, so that the defective bottle caps can be separated in time, avoiding the mixed transportation of defective bottle caps and normal bottle caps, increasing the screening steps of the subsequent processing of the bottle caps, and affecting the processing efficiency of the bottle caps.

[0032] A recycling tank 5 is also provided on the side of the fixing frame 201 away from the production unit 1, and the recycling tank 5 is used to recycle the bottle caps with quality defects after screening by the unloading unit 2. By recycling and reusing the defective bottle caps, waste in the bottle cap production process is reduced and resource utilization is improved.

[0033] The specific implementation process is as follows:

[0034] When unloading the bottle caps produced by the production unit 1, the gripping part 202 moves along the fixed frame 201 to the mold side of the production unit 1, and clamps the bottle caps formed on the mold through the clamping piece 206 on the gripping part 202. The bottle caps are driven by the gripping part 202 to move on the fixed frame 201 in the direction away from the production unit 1. When the fixed frame 201 moves to the side of the dividing rod 4, the bottle caps are moved on the side of the dividing rod 4, so that the material heads on the bottle caps are broken and separated from the bottle caps under the blocking effect of the dividing rod 4; the gripping part 202 places the bottle caps with the material heads separated on the conveyor belt 3, and the conveyor belt 3 conveys the bottle caps to the next processing step, completing the unloading operation of the bottle caps.

[0035] Compared with the prior art, in this solution, when unloading the bottle caps, the formed bottle caps are grabbed and transferred to the conveyor belt 3 on one side of the production unit 1 by the fixed plate 205, so that the bottle caps can be transferred to a position far away from the injection mold in the production unit 1 for transportation during unloading, avoiding the bottle caps from directly falling and contacting with the oil stains falling from the mold during the unloading process, causing the bottle caps to be contaminated and affecting the quality of the bottle caps. In addition, when unloading the bottle caps, by setting the dividing rod 4 during the movement of the bottle caps to the conveyor belt 3, the material heads on the bottle caps can be removed during the process of being transferred to the conveyor belt 3, avoiding the need to remove the material heads of the bottle caps separately after the bottle caps are unloaded, increasing the steps of the bottle cap production and processing, and reducing the efficiency of the bottle cap production and processing.

[0036] It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the technical solution of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The protection scope required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
