Abstract
Description
Technical Field
[0001] This utility model relates to the field of extrusion equipment technology, specifically an extrusion machine. Background Technology
[0002] In daily production, a significant amount of adhesive residue often remains on the inner bags after coating. Currently, the industry commonly uses manual squeezing of the inner bags by workers to remove this adhesive. However, this traditional method has several drawbacks. On the one hand, manual operation is labor-intensive, and prolonged work can lead to worker fatigue, increasing labor costs and worker workload. On the other hand, manual squeezing yields a limited amount of adhesive, making it difficult to completely remove the adhesive from the inner bags, resulting in waste and increased production costs. Therefore, developing an automatic extrusion machine that is easy to operate and can completely remove the adhesive is of significant practical importance. Utility Model Content
[0003] In order to overcome the problems existing in the prior art, the purpose of this utility model is to provide a glue extruder.
[0004] The technical solution adopted by this utility model to solve its technical problem is: a glue extruder, comprising: a frame, a support frame, an active roller, a passive roller, and a gap adjustment assembly; the support frame is installed above the frame, and both ends of the active roller are respectively connected to the two end shafts of the support frame, and one end of the active roller is connected to a motor; both ends of the passive roller are connected to both ends of the gap adjustment assembly, and the gap adjustment assembly is connected to the support frame, pushing the passive roller toward the active roller.
[0005] Main working principle: This extruder uses the relative movement of the active and passive rollers, along with the adjustment of the gap between them by a gap adjustment component, to expel the adhesive from the coated inner bag. The active roller is connected to the two ends of a support frame, and one end is connected to a motor. When the motor starts, it converts electrical energy into mechanical energy, transmitting power to the active roller via the shaft, causing it to rotate around its own axis. This continuous rotation of the active roller provides the power for the entire extrusion process. The passive roller is connected to the two ends of the gap adjustment component, which is in turn connected to the support frame. Initially, the gap adjustment component pushes the passive roller towards the active roller. When the coated inner bag is fed into the gap between the active and passive rollers, friction is generated between them due to the continuous rotation of the active roller driven by the motor. This friction propels the inner bag forward, and during this movement, it is subjected to the squeezing action of both the active and passive rollers. The main function of the gap adjustment component is to adjust the gap between the active and passive rollers to accommodate inner bags of different thicknesses or materials. In actual production, the thickness and material of the inner bags may vary. If the gap is too large, it may not be able to apply sufficient pressure to the inner bag, resulting in incomplete extrusion of the adhesive; if the gap is too small, it may cause excessive compression of the inner bag, or even damage it. With the gap adjustment component, operators can flexibly adjust the gap between the active and passive rollers according to the specific conditions of the inner bag, ensuring that the adhesive is effectively extruded during the extrusion process without damaging the inner bag.
[0006] As the coated inner bag moves forward under the pressure of the active and passive rollers, the adhesive inside is squeezed out through the gaps or openings of the inner bag. The squeezed adhesive flows along the opening of the inner bag and can be collected by a collection device to recycle the adhesive and reduce waste.
[0007] In summary, this extruder uses a motor to drive the active roller to rotate, and utilizes the relative motion of the active and passive rollers, as well as the gap adjustment component to adjust the gap, to extrude the adhesive in the inner bag after coating. It has the advantages of convenient operation and good extrusion effect.

[0009] The base is fixedly connected to the support frame, the lifting adjustment rod is threadedly connected to the base, and the end of the lifting adjustment rod passes through the base and is connected to the connecting rod. The two ends of the connecting rod are provided with connecting blocks, and the two ends of the passive roller are connected to the connecting rod through the connecting blocks.
[0010] Preferably, the connecting rod has guide rods at both ends, and the support frame has guide holes. The size of the guide holes corresponds to the size of the guide rods, and the guide rods pass through the guide holes and connect to the connecting block.
[0011] Preferably, the gap adjustment assembly further includes an elastic element, the connecting block has a connecting cavity, the end of the guide rod is inserted into the connecting cavity, the end of the guide rod can move along the connecting cavity, and the end of the guide rod has a limiting block, which can be pressed against the opening of the connecting cavity for limitation; the elastic element is sleeved around the guide rod, one end of the elastic element is pressed against the guide rod, and the other end of the elastic element is pressed against the connecting block.

The feed end of the support plate is opposite to the gap between the active roller and the passive roller, and the discharge end of the support plate faces away from the active roller and is inclined downward.
[0016] Preferably, the bottom of the frame is provided with casters.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] This invention uses a motor to drive the active roller to rotate, causing the inner bag to pass quickly between the active and passive rollers and complete the extrusion process.

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0027] Example 1
[0028] This embodiment discloses an extrusion machine, such as Figures 1-4As shown, the assembly includes a frame 1, a support frame 2, an active roller 3, a passive roller 4, and a gap adjustment assembly 5. The two ends of the active roller 3 are connected to the two ends of the support frame 2, and one end of the active roller 3 is connected to a motor. When the motor starts, it converts electrical energy into mechanical energy and transmits the power to the active roller 3 through the shaft, causing the active roller 3 to rotate around its own axis. The continuous rotation of the active roller 3 provides the power for the entire extrusion process. The two ends of the passive roller 4 are connected to the two ends of the gap adjustment assembly 5, which is in turn connected to the support frame 2. In the initial state, the gap adjustment assembly 5 pushes the passive roller 4 towards the active roller 3. When the coated inner bag is fed into the gap between the active roller 3 and the passive roller 4, friction is generated between the inner bag and the active roller 3 due to the continuous rotation of the active roller 3 driven by the motor. This friction causes the inner bag to move forward, and during this movement, the inner bag is squeezed by the active roller 3 and the passive roller 4. The main function of the gap adjustment component 5 is to adjust the gap between the active roller 3 and the passive roller 4 to accommodate inner bags of different thicknesses or materials. In actual production, the thickness and material of the inner bags may vary. If the gap is too large, it may not be able to apply sufficient pressure to the inner bag, resulting in incomplete extrusion of the adhesive; if the gap is too small, it may cause excessive compression of the inner bag, or even damage it. Through the gap adjustment component 5, the operator can flexibly adjust the gap between the active roller 3 and the passive roller 4 according to the specific conditions of the inner bag, ensuring that the adhesive is effectively extruded during the extrusion process without damaging the inner bag.
[0029] As the coated inner bag moves forward under the pressure of the active roller 3 and the passive roller 4, the adhesive inside the inner bag is squeezed out through the gaps or holes. The squeezed adhesive flows along the opening of the inner bag and can be collected by a collection device to recycle the adhesive and reduce waste.
[0030] In summary, this extruder uses a motor to drive the active roller 3 to rotate, and utilizes the relative motion between the active roller 3 and the passive roller 4, as well as the gap adjustment component 5 to adjust the gap, to extrude the adhesive in the inner bag after coating. It has the advantages of convenient operation and good extrusion effect.
[0031] In some optional embodiments, the base 51 is fixedly connected to the support frame 2, providing a mounting base for the lifting adjustment rod 50. The lifting adjustment rod 50 is threadedly connected to the base 51, and its end passes through the base 51 and is connected to the connecting rod 52. When the lifting adjustment rod 50 is rotated, due to the interaction of the threads, the lifting adjustment rod 50 will move up and down within the base 51, thereby driving the connecting rod 52 to move up and down. The connecting rod 52 has connecting blocks 53 at both ends, and the two ends of the passive roller 4 are connected to the connecting rod 52 through the connecting blocks 53. Therefore, the up and down movement of the connecting rod 52 will drive the passive roller 4 to move up and down, thereby changing the gap between the active roller 3 and the passive roller 4 to accommodate inner bags of different thicknesses or materials.
[0032] In some optional embodiments, guide rods 54 are provided at both ends of the connecting rod 52, and guide holes corresponding to the size of the guide rods 54 are provided on the support frame 2. The guide rods 54 pass through the guide holes and are connected to the connecting block 53. During the process of the passive roller 4 moving up and down with the connecting rod 52 to adjust the gap, the guide rods 54 slide in the guide holes, playing a guiding role, ensuring that the passive roller 4 remains stable during the movement and does not deviate or shake, ensuring accurate adjustment of the gap between the active roller 3 and the passive roller 4, and improving the stability and quality of extrusion.
[0033] In some optional embodiments, the connecting block 53 has a connecting cavity 56, the end of the guide rod 54 is inserted into the connecting cavity 56 and can move along the connecting cavity 56, and the end is provided with a limiting block 57 to prevent the guide rod 54 from coming out of the connecting cavity 56. The elastic element 55 is sleeved around the guide rod 54, with one end pressing against the guide rod 54 and the other end pressing against the connecting block 53. When the inner bag enters between the active roller 3 and the passive roller 4, if the thickness of the inner bag is uneven or it is subjected to abnormal extrusion force, the end of the guide rod 54 will move in the connecting cavity 56, and the elastic element 55 will be compressed or stretched, playing a buffering role to avoid excessive extrusion and damage to the inner bag. At the same time, it allows the passive roller 4 to adaptively adjust according to the actual situation of the inner bag to ensure the smooth progress of the extrusion process.
[0034] In some optional embodiments, the lifting adjustment rod 50 is provided with an operating handle 6 at its end, which the operator can manually rotate to drive the lifting adjustment rod 50 to rotate. Compared with directly rotating the lifting adjustment rod 50, the operating handle 6 provides a more convenient point of force, allowing the operator to adjust the lifting adjustment rod 50 more easily and accurately, thereby realizing the adjustment of the gap between the active roller 3 and the passive roller 4, improving the ease of operation and adjustability of the equipment.
[0035] In some optional embodiments, the guide plate 7 is installed on the extrusion side of the active roller 3, with its feed end facing the gap between the active roller 3 and the passive roller 4, and its discharge end facing away from the active roller 3 and inclined downwards. When the inner bag is squeezed between the active roller 3 and the passive roller 4, the extruded adhesive flows out from the gap and flows downwards along the inclined surface of the guide plate 7, thereby achieving the collection and guidance of the adhesive, facilitating subsequent recycling of the adhesive, and preventing the adhesive from flowing randomly and polluting the working environment.
[0036] In some optional embodiments, baffles 8 are provided on both sides of the guide plate 7. When the adhesive flows along the guide plate 7, the baffles 8 can prevent the adhesive from overflowing from both sides of the guide plate 7, ensuring that the adhesive can flow along the predetermined path of the guide plate 7, further improving the accuracy and efficiency of adhesive collection and maintaining a clean working environment.
[0037] In some optional embodiments, the support plate 9 is installed on the bag outlet side of the active roller 3, with its feed end facing the gap between the active roller 3 and the passive roller 4, and its discharge end facing away from the active roller 3 and inclined downwards. After being squeezed, the inner bag comes out from the gap between the active roller 3 and the passive roller 4 and falls onto the support plate 9, sliding out along the inclined surface of the support plate 9, which guides the discharge of the inner bag, allowing it to leave the extruder smoothly and orderly, facilitating subsequent collection and processing.
[0038] In some optional embodiments, the bottom of the frame 1 is provided with rollers 10. When the extruder needs to be moved, the operator only needs to apply a certain external force, and the extruder can be easily moved between different positions by the rolling of the rollers 10. This eliminates the need for laborious handling, improves the mobility and flexibility of the equipment, and makes it convenient to use in different production sites or production processes.
[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
