Description

Technical Field

[0001] This invention relates to the field of testing technology for the ultimate drop angle of packaging bags, and more specifically to an ultimate drop angle tester for packaging bags. Background Technology

[0002] Under the existing technology, when designing the tilt angle of conveyor belts, roller conveyors, and chutes, it is necessary to ensure that the angle is less than the limit sliding angle of the packaging bag; otherwise, the packaging bag will slide too fast or accumulate and block during the conveying process.

[0003] Currently, there is no convenient packaging bag limit drop angle tester to measure the limit drop angle of the packaging bag, so as to assist in the design of related equipment such as conveyor belts, roller lines, and chutes with reasonable tilt angles;

[0004] Furthermore, the placement platform of the existing packaging bag limit drop angle testing device often becomes contaminated with dust and other impurities during long-term use, which causes changes in the surface roughness of the placement platform and affects the accuracy of the device in measuring the limit drop angle of the packaging bag.

[0005] Therefore, in order to solve the above problems, there is a need to provide a limit drop angle tester for packaging bags. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a limit drop angle tester for packaging bags to solve the problems existing in the background art.

[0007] The present invention provides the following technical solution: a limit drop angle tester for packaging bags, comprising a platform tilt adjustment mechanism, on which a packaging bag is placed, and the limit drop angle of the packaging bag is measured by continuously changing the platform tilt angle of the platform tilt adjustment mechanism.

[0008] Furthermore, the platform tilt adjustment mechanism includes a platform base with lugs on both sides and sliding grooves on each lug. A threaded groove is located in the middle of the platform base. A test platform is movably mounted on top of the platform base. Sliding surfaces are provided on both sides of the test platform, and these sliding surfaces are movably fitted with the lugs. A fitting shaft is fixedly mounted at the bottom of the sliding surface and is movably fitted in the sliding groove. Limit plates are installed at the bottom end of the fitting shaft. Two shaft supports are fixedly mounted at the middle of the bottom of the test platform. A threaded rod is movably fitted between the shaft supports and engages with the threaded groove for transmission. A servo motor is fixedly connected to the end of the threaded rod. A fixing rod is fixedly connected to the inner side of the servo motor, and the servo motor is fixedly mounted on the outer surface of the shaft supports via the fixing rod.

[0009] Furthermore, a tilt sensor is installed at the bottom of the test platform, and an output port is provided on the outside of the test platform. The tilt sensor is electrically connected to the output port.

[0010] Furthermore, a receiving component is installed at the bottom front end of the platform tilt adjustment mechanism. The receiving component includes a base plate, which is fixedly installed at the bottom of the platform base. A receiving seat plate is fixedly installed at the front end of the base plate. An installation groove is provided on the receiving seat plate, and a pressure sensor is installed in the installation groove. Elastic telescopic shafts are installed at the four corners of the installation groove of the receiving seat plate. A receiving plate is installed on the pressure sensor, and the bottom four corners of the receiving plate are connected to the top of the shaft of the elastic telescopic shaft.

[0011] Furthermore, the pressure sensor is electrically connected to the servo motor, and the pressure sensor controls the servo motor to stop.

[0012] Furthermore, a cleaning assembly is provided on the rear side of the platform tilt adjustment mechanism. The cleaning assembly includes a base, which is fixedly installed on the rear side of the base plate. An electric cylinder is fixedly installed on the base, and a push rod is fixedly connected to the drive end of the electric cylinder. A cleaning plate is fixedly installed at the end of the shaft of the push rod. The bottom cleaning surface of the cleaning plate is flush with the upper surface of the test platform when it is in a horizontal state. A vertical plate is fixedly installed on the front of the base, and the shaft of the push rod is sleeved on the vertical plate.

[0013] Furthermore, the bottom of the cleaning assembly is provided with a collection assembly, which includes two cleaning motors symmetrically distributed on both sides. The cleaning motors are fixedly installed in the upright plate, and each cleaning motor's drive shaft is fixedly sleeved with a rotating roller. A brush belt is driven between the rotating rollers, and the upper surface of the brush belt contacts the bottom cleaning surface of the cleaning plate in the retracted state. A collection box is fixedly installed at the front end of the upright plate, and a grid groove is opened on the upper surface of the collection box. The upper surface of the collection box contacts the bottom surface of the brush belt. A filter plate is fixedly installed on the inner wall of the collection box near the outer side, and an end plate is fixedly installed at the outer end of the collection box. A fan is installed on the end plate.

[0014] The technical effects and advantages of this invention are as follows:

[0015] 1. This invention includes a platform tilt adjustment mechanism and a receiving component. A packaging bag is placed on the test platform, and then a servo motor is started to drive a threaded rod to rotate. Under the action of the threaded groove, the rotating threaded rod causes the test platform to tilt on the platform base, thereby gradually changing the tilt angle of the test platform. The tilt angle sensor records the tilt angle data of the test platform and can output the data through the output port. This method enables the device to measure the ultimate drop angle of the packaging bag. As the test platform gradually changes its tilt angle, the packaging bag placed on the test platform reaches its ultimate drop angle and slides off the test platform, falling onto the receiving plate. The elastic telescopic shaft provides cushioning. After the pressure sensor detects the pressure, it transmits an electrical signal to the servo motor and controls the servo motor to stop, thus facilitating the measurement of the tilt angle of the test platform at this time.

[0016] 2. This invention includes a cleaning component and a collection component. When the test platform returns to a horizontal state, the electric cylinder drives the push rod to push the cleaning plate to clean the upper surface of the test platform, thereby maintaining the cleanliness of the upper surface of the test platform and preventing dust and other impurities from affecting the measurement results of the extreme drop angle of the packaging bag. After the cleaning plate completes the cleaning work, its cleaning surface will be contaminated with dust and other impurities. The cleaning motor starts synchronously and controls the rotating rollers on both sides to rotate in the same direction, thereby driving the brush belt to operate. The brush belt cleans the bottom cleaning surface of the cleaning plate. During the cleaning process, the dust and other impurities generated fall into the upper surface of the collection box. Driven by the fan, the internal space of the collection box is created with negative pressure, thereby absorbing the falling dust and other impurities through the grid groove. The filter plate intercepts and filters the dust and other impurities. The above method realizes the automatic cleaning function of the cleaning plate of this device. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The packaging bag limit drop angle tester involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Reference Figure 1 The present invention provides a limit drop angle tester for packaging bags, including a platform tilt adjustment mechanism 1, a receiving component 2 installed at the bottom front end of the platform tilt adjustment mechanism 1, a cleaning component 3 provided at the rear side of the platform tilt adjustment mechanism 1, and a collecting component 4 provided at the bottom of the cleaning component 3.

[0026] In this embodiment, the packaging bag is placed on the measuring platform of the platform tilt adjustment mechanism 1, and the extreme drop angle of the packaging bag is tested by the platform tilt adjustment mechanism 1. The receiving component 2 can receive the dropped packaging bag, the cleaning component 3 is used to clean the measuring platform of the platform tilt adjustment mechanism 1, and the collecting component 4 is used to clean the cleaning component 3. The specific structure and working principle of the above components will be explained in detail later.

[0027] Reference Figure 2The platform tilt adjustment mechanism 1 includes a platform base 101, with lugs 102 on both sides of the platform base 101. Each lug 102 has a sliding groove 103. A threaded groove 104 is located in the middle of the platform base 101. A test platform 105 is movably mounted on top of the platform base 101. Sliding surfaces 106 are provided on both sides of the test platform 105. The sliding surfaces 106 are movably fitted with the lugs 102. A fitting shaft 107 is fixedly mounted at the bottom of the sliding surface 106 and movably fitted in the sliding groove 103. A limit plate 108 is installed at the bottom end of the shaft of the fitting shaft 107. Two shaft supports 109 are fixedly installed at the bottom center of the test platform 105. A threaded rod 110 is movably sleeved between the shaft supports 109. The threaded rod 110 is engaged with a threaded groove 104 for transmission. A servo motor 111 is fixedly connected to the end of the shaft of the threaded rod 110. A fixing rod 112 is fixedly connected to the inner side of the servo motor 111. The servo motor 111 is fixedly installed on the outer side of the shaft support 109 through the fixing rod 112. An tilt sensor 113 is installed at the bottom of the test platform 105. An output port 114 is provided on the outer side of the test platform 105. The tilt sensor 113 is electrically connected to the output port 114.

[0028] In this embodiment, the packaging bag is placed on the test platform 105, and then the servo motor 111 is started to drive the threaded rod 110 to rotate. Under the action of the threaded groove 104, the rotation of the threaded rod 110 causes the test platform 105 to tilt on the platform base 101, thereby gradually changing the tilt angle of the test platform 105. The tilt angle sensor 113 records the tilt angle data of the test platform 105 and can output the data through the output port 114. The device can measure the extreme drop angle of the packaging bag in the above manner.

[0029] Reference Figure 3 and Figure 4 The receiving component 2 includes a base plate 201, which is fixedly installed on the bottom of the platform base 101. A receiving seat plate 202 is fixedly installed on the front end of the base plate 201. The receiving seat plate 202 has an installation groove. A pressure sensor 203 is installed in the installation groove of the receiving seat plate 202. Elastic telescopic shafts 204 are installed at the four corners of the installation groove of the receiving seat plate 202. A receiving plate 205 is installed on the pressure sensor 203. The bottom four corners of the receiving plate 205 are connected to the top of the shaft of the elastic telescopic shaft 204. The pressure sensor 203 is electrically connected to the servo motor 111 and controls the servo motor 111 to stop.

[0030] In this embodiment, when the test platform 105 gradually changes its tilt angle, the packaging bag placed on the test platform 105 will slide off the test platform 105 after reaching its limit sliding angle, and fall onto the receiving plate 205. The elastic telescopic shaft 204 provides cushioning for it. After the pressure sensor 203 detects the pressure, it transmits an electrical signal to the servo motor 111 and controls the servo motor 111 to stop, so that the tilt angle of the test platform 105 can be measured at this time.

[0031] Reference Figure 5 The cleaning assembly 3 includes a base 301, which is fixedly installed on the rear side of the base plate 201. An electric cylinder 302 is fixedly installed on the base 301. A push rod 303 is fixedly connected to the drive end of the electric cylinder 302. A cleaning plate 304 is fixedly installed at the end of the shaft of the push rod 303. The bottom cleaning surface of the cleaning plate 304 is flush with the upper surface of the test platform 105 when it is in a horizontal state. A vertical plate 305 is fixedly installed at the front of the base 301. The shaft of the push rod 303 is sleeved on the vertical plate 305.

[0032] In this embodiment, when the test platform 105 returns to a horizontal state, the push rod 303 driven by the electric cylinder 302 pushes the cleaning brush plate 304 to clean the upper surface of the test platform 105, thereby maintaining the cleanliness of the upper surface of the test platform 105 and preventing dust and other impurities from affecting the measurement results of the extreme drop angle of the packaging bag.

[0033] Reference Figure 6 The collection component 4 includes two cleaning motors 401, which are symmetrically distributed on both sides. The cleaning motors 401 are fixedly installed in the vertical plate 305. The drive shafts of the cleaning motors 401 are fixedly sleeved with rotating rollers 402. A brush belt 403 is sleeved between the rotating rollers 402. The upper surface of the brush belt 403 is in contact with the bottom cleaning surface of the cleaning brush plate 304 in the retracted state. A collection box 404 is fixedly installed at the front end of the vertical plate 305. A grid groove 405 is opened on the upper surface of the collection box 404. The upper surface of the collection box 404 is in contact with the bottom surface of the brush belt 403. A filter plate 406 is fixedly installed on the inner wall of the collection box 404 near the outer side. An end plate 407 is fixedly installed at the outer end of the collection box 404. A fan 408 is installed on the end plate 407.

[0034] In this embodiment, after the cleaning brush plate 304 completes its cleaning work, its cleaning surface will be contaminated with dust and other impurities. The cleaning motor 401 starts synchronously and controls the rotating rollers 402 on both sides to rotate in the same direction, thereby driving the brush belt 403 to operate. The brush belt 403 cleans the bottom cleaning surface of the cleaning brush plate 304. During the cleaning process, the dust and other impurities generated fall into the upper surface of the collection box 404. Driven by the fan 408, a negative pressure is generated in the internal space of the collection box 404, thereby absorbing the falling dust and other impurities through the grid groove 405. The filter plate 406 intercepts and filters the dust and other impurities. The automatic cleaning function of the cleaning brush plate 304 is achieved by the above method.

[0035] The working principle of this invention is as follows: When using the device, the packaging bag is placed on the test platform 105, and then the servo motor 111 is started to drive the threaded rod 110 to rotate. Under the action of the threaded groove 104, the rotation of the threaded rod 110 causes the test platform 105 to tilt on the platform base 101, thereby gradually changing the tilt angle of the test platform 105. The tilt angle sensor 113 records the tilt angle data of the test platform 105 and can output the data through the output port 114. In this way, the device can measure the ultimate drop angle of the packaging bag. When the test platform 105 gradually changes its tilt angle, the packaging bag placed on the test platform 105 will slide off the test platform 105 after reaching its ultimate drop angle, and fall onto the receiving plate 205. The elastic telescopic shaft 204 provides cushioning. After the pressure sensor 203 detects the pressure, it transmits an electrical signal to the servo motor 111 and controls the servo motor 111 to stop, thus facilitating the measurement of the tilt angle of the test platform 105 at this time. When the test platform 105 returns to a horizontal state, the electric cylinder 302 drives the push rod 303 to push the cleaning brush plate 304 to clean the upper surface of the test platform 105, thereby maintaining the cleanliness of the upper surface of the test platform 105 and preventing dust and other impurities from affecting the measurement results of the limit drop angle of the packaging bag. After the cleaning brush plate 304 completes the cleaning work, its cleaning surface will be contaminated with dust and other impurities. The cleaning motor 401 starts synchronously and controls the rotating rollers 402 on both sides to rotate in the same direction, thereby driving the brush belt 403 to rotate. The brush belt 403 cleans the bottom cleaning surface of the cleaning brush plate 304. During the cleaning process, the dust and other impurities generated fall into the upper surface of the collection box 404. Driven by the fan 408, the internal space of the collection box 404 is created with negative pressure, thereby absorbing the falling dust and other impurities through the grid groove 405. The filter plate 406 intercepts and filters the dust and other impurities. In this way, the automatic cleaning function of the cleaning brush plate 304 is realized by the device.
