Description

Technical Field

[0001] This utility model belongs to the field of testing equipment technology, and specifically relates to a testing template overlap device. Background Technology

[0002] For manufacturers producing templates (such as wall panels for home decoration, titanium-magnesium fireproof boards, etc.), during the production process, errors in operation or unevenness of the templates can cause overlapping templates, leading to machine jamming. This necessitates stopping the machine for repairs. It requires manual adjustment of the two pressure rollers to the maximum gap until the templates loosen, and then manually pulling the overlapping templates back and re-laying them. This is extremely labor-intensive and may even crack the distributor of the transmission mechanism, requiring replacement of the distributor. The entire process is time-consuming, labor-intensive, and seriously affects the completion of production tasks.

[0003] In conclusion, how to solve the problem of template overlap during the production process has become a production technology problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a device for detecting template overlap, comprising a conveying mechanism, on which a pressure roller mechanism is provided, the pressure roller mechanism comprising a connecting column and a crossbeam, the connecting column being fixedly installed on the conveying mechanism, and the crossbeam being connected to the connecting column by connecting bolts; a plurality of pressure rollers are provided on the lower surface of the crossbeam; and limit switches are provided on the side surface of the crossbeam.

[0005] The distance between the limit switch and the conveying mechanism is less than the thickness of the two overlapping templates.

[0006] Furthermore, the detection template overlap device also includes adjusting bolts.

[0007] A mounting base is provided on the side surface of the crossbeam, and the adjusting bolt passes through the mounting base and abuts against the limit switch.

[0008] Furthermore, the crossbeam is a 40mm x 60mm square tube.

[0009] Furthermore, a cleaning pipe is installed on the beam.

[0010] Furthermore, the conveying mechanism includes a first conveying mechanism, a second conveying mechanism, and a third conveying mechanism arranged in sequence, and at least one pressure roller mechanism is provided on the first conveying mechanism and / or the second conveying mechanism and / or the third conveying mechanism.

[0011] Furthermore, an emergency stop button is provided on the first, second, or third conveying mechanism.

[0012] Furthermore, several inclined panels are provided on the first conveying mechanism.

[0013] Furthermore, a pressure roller mechanism is provided at the end of the third conveying mechanism away from the second conveying mechanism. The pressure roller mechanism includes a first pressure roller and a second pressure roller, which are rotatably mounted on the third conveying mechanism.

[0014] Furthermore, the pressure roller mechanism also includes an adjusting turntable, a lead screw, and a sliding block, wherein the sliding block is slidably installed in the mounting groove of the third conveying mechanism; and the first pressure roller is rotatably installed in the sliding block.

[0015] The lead screw is rotatably installed in the mounting groove and threadedly connected to the sliding block; an adjustment turntable is provided at the upper end of the lead screw.

[0016] Furthermore, the pressure roller mechanism also includes a drive motor, which is fixedly mounted on the side surface of the third conveying mechanism and is connected to the second pressure roller in a transmission manner.

[0017] Beneficial effects:

[0018] 1. This utility model sets a limit switch so that the distance between the limit switch and the conveying mechanism is less than the thickness of the overlapping template. This allows for real-time detection of the overlapping template. When the overlapping template touches the limit switch, the entire equipment stops working immediately, preventing the overlapping template from entering between the first and second pressure rollers and causing downtime and delaying production.

[0019] 2. By setting up several pressure rollers, this utility model can flatten and straighten the unevenness of the two ends of the template, thereby reducing the occurrence of template overlap.

[0020] 3. This utility model has a cleaning pipe installed on the crossbeam. The cleaning pipe blows away the debris on the template, ensuring that the template surface is clean before production begins.

[0021] 4. This utility model features an emergency stop button that, when pressed by an operator in an emergency, cuts off the power to the entire equipment. The emergency stop button serves to cut off power in case of an emergency and, in conjunction with the limit switch, provides dual protection.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] This utility model discloses a device for detecting template overlap. This device is primarily designed for manufacturers producing templates (such as wall panels for home decoration, titanium-magnesium fireproof boards, etc.). During the production process, due to prolonged use, templates are prone to deformation (warping at both ends, unevenness, etc.). The templates are sucked onto a first conveying mechanism 10 by a suction machine. The first conveying mechanism 10, the second conveying mechanism 20, and the third conveying mechanism 30 sequentially transport the templates one by one to the next process. (The transmission speed of the second conveying mechanism 20 is greater than that of the first and third conveying mechanisms 10 and 30, ensuring that each template is sequentially joined on the third conveying mechanism 30 before entering the next process.) Before entering the next process, due to the template... Deformation can easily occur during the transfer of templates, causing overlap between the front and rear templates. Since the next process consists of the first pressure roller 61 and the second pressure roller 62, the templates begin to be made after entering the next process. If the templates overlap, they cannot pass through the first pressure roller 61 and the second pressure roller 62 (there is a certain gap of 10mm between the first pressure roller 61 and the second pressure roller 62). If the thickness exceeds the thickness of two templates (each template is 7mm thick), it will not be able to pass through the first pressure roller 61 and the second pressure roller 62, and the template will get stuck. This requires stopping the machine for repair. The first pressure roller 61 and the second pressure roller 62 need to be manually adjusted to raise them to the maximum gap until the template is loosened, and then the overlapping templates need to be manually pulled back and re-laid. The labor intensity is extremely high, which seriously affects the completion of the titanium-magnesium board production task (1000 sheets per shift).

[0035] To address the above problems, the following technical solutions are adopted: Figure 2 As shown, Figure 2 A schematic diagram of the first and second conveying mechanisms of the template overlap detection device in an embodiment of this utility model is shown. (Reference) Figure 2 A device for detecting template overlap includes a conveying mechanism with a pressure roller mechanism 90. The pressure roller mechanism 90 includes a connecting column 91 and a crossbeam 92. The connecting column 91 is fixedly mounted on the conveying mechanism, and the crossbeam 92 is connected to the connecting column 91 by connecting bolts 93. A plurality of pressure rollers 94 are provided on the lower surface of the crossbeam 92. Limit switches 41 (such as...) are provided on the side surface of the crossbeam 92. Figure 3(As shown); Specifically, three pressure rollers 94 are provided, and the pressure rollers 94 can rotate as the template moves to reduce the friction between the template and the template. At the same time, the pressure rollers 94 can correct uneven templates and prevent templates from overlapping; the pressure rollers 94 are plastic wheels with a standard diameter of 60mm. The first conveying mechanism 10, the second conveying mechanism 20 and the third conveying mechanism 30 are all composed of conveyor belts and motors, and the templates are transported by the conveyor belts;

[0036] Specifically, when overlapping templates pass through the conveying mechanism, the overlapping templates contact the limit switch 41, causing the entire equipment to stop working. Specifically, the crossbeam 92 uses a 40mm x 60mm square tube, which is lightweight and reliable. The 1480mm long crossbeam 92 is installed on the frame of the conveying mechanism (fixed by connecting bolts 93 and connecting columns 91). The three sets of pressure rollers 94 for pressing the templates are arranged at a certain distance (540mm). The limit switch 41 is 10mm away from the first conveying mechanism 10. Once the templates overlap and the thickness exceeds the thickness of two templates (14mm), the overlapping templates contact the limit switch 41, causing the entire conveying mechanism to lose power. The emergency stop button 70 also serves as a double safety measure for power outages in case of emergencies.

[0037] The limit switch 41 is a normally closed contact model WLCA12. Since the thickness of the template is twice that of the original after overlapping, the limit switch 41 will retract and cut off the power immediately when it touches the template. In this way, the equipment will stop operating. When the templates overlap, the overlapping templates must be pulled back manually and re-laid on the conveyor mechanism.

[0038] The purpose of this invention is to provide a device for detecting overlapping templates, so that problems can be detected and addressed before the templates overlap, rather than being discovered and addressed only after they get stuck in the first pressure roller 61 and the second pressure roller 62. This can effectively improve production efficiency, eliminate the time wasted in dealing with overlapping templates, greatly reduce the labor intensity of workers, and avoid safety hazards.

[0039] In this embodiment of the invention, the detection template overlap device further includes an adjusting bolt 42, and a mounting base 95 is provided on the side surface of the crossbeam 92. The adjusting bolt 42 passes through the mounting base 95 and abuts against the limit switch 41. The distance between the limit switch 41 and the conveying mechanism is less than the thickness of the two overlapping templates.

[0040] Specifically, the limit switch 41 is fixedly connected to the mounting base 95 by turning the adjusting bolt 42, thereby fixing the limit switch 41. At the same time, when it is necessary to adjust the position of the limit switch 41, the limit switch 41 is loosened by turning the adjusting bolt 42, the position of the limit switch 41 is manually adjusted, and then the limit switch 41 is fixed by turning the adjusting bolt 42.

[0041] refer to Figure 1 The conveying mechanism includes a first conveying mechanism 10, a second conveying mechanism 20, and a third conveying mechanism 30 arranged sequentially. At least one pressure roller mechanism 90 is provided on the first conveying mechanism 10 and / or the second conveying mechanism 20 and / or the third conveying mechanism 30. Specifically, in this invention, one pressure roller mechanism 90 is provided on the first conveying mechanism 10 and the second conveying mechanism 20 respectively, and two pressure roller mechanisms 90 are provided on the third conveying mechanism 30.

[0042] Specifically, a cleaning pipe 50 is installed on the crossbeam 92 (see reference). Figure 4 The cleaning tube 50 blows away debris from the template, ensuring the template surface is clean before production begins. The cleaning tube 50 is connected to the blower, which provides airflow to clean the debris from the template.

[0043] Specifically, an emergency stop button 70 is provided on the first conveyor mechanism 10, the second conveyor mechanism 20, or the third conveyor mechanism 30. In case of an emergency, the worker can press the button to cut off the power to the entire equipment. The emergency stop button 70 serves as a power cut-off function in case of an emergency, and together with the limit switch 41, it provides double protection. The emergency stop button 70 is a LAY7-11ZS self-locking emergency stop button. Several inclined panels 80 are provided on the first conveyor mechanism 10. The inclined panels 80 are used to limit the position of the template. The template is picked up by the suction plate machine and placed on the first conveyor mechanism 10. During placement, the inclined panels 80 limit the position (see reference). Figure 6 This prevents the template from going astray.

[0044] refer to Figure 5 The output end of the third conveying mechanism 30 is equipped with a pressure roller mechanism 60, which includes a first pressure roller 61 and a second pressure roller 62, which are rotatably mounted on the third conveying mechanism 30. When the templates overlap, they cannot pass through the gap between the first pressure roller 61 and the second pressure roller 62 (the gap between the first pressure roller 61 and the second pressure roller 62 is 8mm). If the thickness exceeds the thickness of two templates (template thickness 7mm), they will not pass through the gap between the first pressure roller 61 and the second pressure roller 62, causing the templates to jam. This can also cause the outer shell of the transmission mechanism (distributor) of the third conveying mechanism 30 to crack. As a result, the machine must be stopped for repair. The first pressure roller 61 and the second pressure roller 62 must be manually adjusted to increase the maximum gap, and the overlapping templates must be manually pulled back and re-laid. This is extremely labor-intensive and seriously affects the completion of the titanium-magnesium board production task (1000 sheets per shift). In addition, two sets of cleaning pipes 50 are installed on the crossbeam 92 of the first set of pressure roller mechanism 90 to blow away dust and other debris from the templates.

[0045] In the above embodiment, another optional implementation is that the pressure roller mechanism 60 further includes an adjusting turntable 63, a lead screw 64, and a sliding block 65. The sliding block 65 is slidably installed in the mounting groove 31 of the third conveying mechanism 30; the first pressure roller 61 is rotatably installed in the sliding block 65; the lead screw 64 is rotatably installed in the mounting groove 31 and threadedly connected to the sliding block 65; the adjusting turntable 63 is provided at the upper end of the lead screw 64. By manually rotating the adjusting turntable 63, the lead screw 64 is rotated, which in turn causes the sliding block 65 and the first pressure roller 61 to move up and down, thereby adjusting the gap between the first pressure roller 61 and the second pressure roller 62, thus accommodating templates of different thicknesses. At the same time, when the templates overlap and jam, the templates can be easily removed.

[0046] Specifically, the pressure roller mechanism 60 also includes a drive motor 66, which is fixedly mounted on the outer surface of the second conveying mechanism 20 and is connected to the second pressure roller 62 in a transmission manner. The drive motor 66 is used to drive the second pressure roller 62 to rotate, thereby providing power.

[0047] Working Principle: During operation, the templates are sequentially placed at intervals onto the first conveying mechanism 10 using a suction plate machine (ensuring gaps between adjacent templates). The first conveying mechanism 10 has an inclined panel 80, which limits the templates and prevents them from deviating. The templates are then sequentially conveyed to the second conveying mechanism 20 via the first conveying mechanism 10. Since the speeds of the first and third conveying mechanisms 10 and 30 are lower than the speed of the second conveying mechanism 20, the templates are connected end-to-end as they pass from the second to the third conveying mechanism 30. When the templates pass through the pressure roller mechanism 90, the pressure roller 90... 4. As the template moves, it rotates, thereby reducing the friction between the pressure roller 94 and the template and correcting any warped edges of the template. When the templates end to end overlap, the overlapping templates touch the limit switch 41, causing the entire device to stop. The overlapping templates are then manually pulled out, and the machine is restarted to continue working. The templates enter the first pressure roller 61 and the second pressure roller 62 through the first conveying mechanism 10, the second conveying mechanism 20 and the third conveying mechanism 30. Before entering the first pressure roller 61 and the second pressure roller 62, the cleaning pipe 50 set on the crossbeam 92 blows away the debris on the templates, ensuring that the surface of the templates is clean before the production of templates begins.

[0048] In case of an emergency, the power to the entire equipment can be cut off by pressing the emergency stop button 70. When the equipment is processing templates of different thicknesses, the turntable 63 can be rotated manually, which in turn rotates the lead screw 64, causing the sliding block 65 and the first pressure roller 61 to move up and down, thereby adjusting the gap between the first pressure roller 61 and the second pressure roller 62 to accommodate templates of different thicknesses. By adjusting the relative positions between the connecting column 91 and the crossbeam 92 and then fixing them with the connecting bolt 93, the distance between the pressure roller 94 and the conveying mechanism can be adjusted. At the same time, when it is necessary to adjust the position of the limit switch 41, the limit switch 41 can be loosened by turning the adjusting bolt 42, and the position of the limit switch 41 can be manually adjusted. Then, the limit switch 41 can be fixed by turning the adjusting bolt 42, thereby accommodating templates of different thicknesses.

[0049] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
