[0049] The present application can store a sufficient amount of glue particles by setting up a loading device 2, and can output the glue particles to the feeding device 3 through the output end of the loading device 2. The feeding device 3 is provided with an inlet corresponding to the output end, which can continuously receive the glue particles output from the loading device 2, and the glue particles can be output to the receiving device 4 through the feeding port 10 during the transportation of the glue particles in the feeding device 3, thereby realizing stable transportation of the glue particles and controlling the transportation amount of the glue particles; the telescopic component 41 of the receiving device 4 can drive the receiving box 42 to move toward the feeding port 10 and carry the glue particles output from the feeding port 10, and then drive the receiving box 42 to move toward the side of the glue sprayer 11 under the action of the telescopic component 41, so as to unload all the carried glue particles into the glue sprayer 11, thereby realizing centralized discharge of the glue particles without causing glue leakage.

[0050] As a preferred embodiment of the present application, the telescopic assembly 41 includes a support seat 411 and a telescopic member 412; the top of the support seat 411 has a guide slope inclined at the base 1, and the guide slope is inclined downward toward one side of the glue sprayer 11, so that the telescopic member 412 connected to the top of the support seat 411 is inclined downward; one side of the material receiving box 42 is connected in parallel with the telescopic member 412, and the material receiving box 42 is driven to move by the telescopic movement of the telescopic member 412.

[0051] like Figure 4 As shown, the support seat 411 is arranged at an angle so that the telescopic member 412 above the support seat 411 can be arranged at an angle. Since the telescopic member 412 is connected to the material receiving box 42, the material receiving box 42 is arranged at an angle. Since a certain number of glue particles are carried in the material receiving box 42, the glue particles in the material receiving box 42 can reach the specified position of the glue sprayer 11 under the driving action of the telescopic component 41, and the glue particles in the material receiving box 42 can freely fall from the inclined material receiving box 42 to the glue sprayer 11 under the action of gravity.

[0052] It is worth noting that the telescopic member 412 can be a cylinder, which is connected to the support seat 411 and has a telescopic rod. The telescopic rod, as the telescopic member 412, can drive the receiving box 42 to move back and forth.

[0053] Specifically, a support is connected to the bottom of the material receiving box 42 , and the support is connected to one end of the telescopic member 412 .

[0054] In addition, the support seat 411 of the telescopic component 41 of the material receiving device is provided with a sensor for judging whether the retracted position is in place; and the bottom of the material receiving box 42 is provided with a sensor for judging whether the extended position is in place and providing a completion signal.

[0055] As a preferred embodiment of the present application, the glue sprayer 11 has an opening corresponding to the material receiving box 42, and the opening of the glue sprayer 11 is connected to a cover opening assembly; the cover opening assembly includes a top cover, a driving device and a connecting assembly; the top cover is hingedly connected to the glue sprayer 11, the driving device is connected to the base 1, and the driving device drives the top cover to open or close through the connecting assembly.

[0056] In order to enable the glue particles in the material receiving box 42 to smoothly enter the interior of the glue spraying machine 11, an opening is opened at the position of the glue spraying machine 11 corresponding to the material receiving box, and an opening component that can open or close the opening is connected to the opening; the top cover in the opening component is used to seal the opening, the driving device is connected to the base 1, the connecting component is connected between the opening component and the driving device, and the driving device can drive the top cover to open or close relative to the opening through the connecting component. When the glue particles in the material receiving box 42 need to be unloaded into the glue spraying machine 11, the driving device drives the connecting component to drive the top cover to open, and the telescopic component 41 drives the material receiving box 42 to move toward the side of the glue spraying machine 11. When the material receiving box 42 reaches the top of the opening, the glue particles slide into the opening under the action of their own weight.

[0057] As a preferred embodiment of this embodiment, the connecting assembly includes a connecting shaft, a rotating shaft and a cylinder; the cylinder is connected to the base 1, the telescopic rod of the cylinder is rotatably connected to the connecting end of the rotating shaft, the fixed end of the rotating shaft is fixedly connected to the connecting shaft, the connecting shaft and the rotating shaft are vertically arranged, and the connecting shaft is fixedly connected to the top of the top cover near the hinged side through a pin shaft or a pin or other fixing parts; the two sides of the open cover are hingedly connected to the inner wall of the opening of the glue sprayer 11; when in use, when the telescopic rod is driven by the cylinder to extend toward one side of the glue sprayer 11, due to The connecting end of the rotating shaft is rotatably connected to the telescopic rod, and the fixed end of the rotating shaft is fixedly connected to the top cover via the connecting shaft, so the connecting end of the rotating shaft can be driven to rotate relative to the telescopic rod and move toward the side of the glue sprayer 11. Since the fixed end of the rotating shaft is fixed to the top cover via the connecting shaft, when the rotating shaft rotates relative to the telescopic rod, the connecting shaft can be driven to rotate. Since the connecting shaft is fixed to the top cover, the top cover can be driven to rotate relative to the telescopic rod toward the side of the glue sprayer 11, thereby realizing the opening of the top cover. Similarly, when the telescopic rod is shortened, the top cover can be driven to close.

[0058] In addition, the cover opening assembly also includes a cover opening position sensor and a closing position sensor. The cover opening position sensor is used to detect whether the top cover is open, and the closing position sensor is used to detect whether the top cover is closed, so as to cooperate with the material receiving device to complete the feeding into the glue spraying machine 11.

[0059] As a preferred embodiment of the present application, the feeding device 3 includes a connecting seat 31, a shell 32, a motor 33 and an auger 34; the shell 32 is connected to the connecting seat 31, and the two ends of the auger 34 along the axial direction are rotatably connected to the shell 32 through bearing assemblies, and one end of the auger 34 can extend out of the shell 32 and be rotatably connected to the drive shaft of the motor 33.

[0060] like Figure 2As shown, the connection seat 31 of the feeding device 3 is used to support the shell 32, and the shell 32 is rotatably connected with an auger 34. One end of the auger 34 can extend out of the shell 32 and connect with the drive shaft of the motor 33 through a coupling, so that the motor 33 drives the auger 34 to rotate inside the shell 32. The rotation of the auger 34 can drive the quantitative delivery of the rubber particles falling into the shell 32 to the feeding port 10, so as to achieve stable and concentrated output of the rubber particles. The motor of the feeding device adopts a servo motor, and the number of rotations can be controlled by the servo motor drive to achieve precise feeding.

[0061] As a preferred embodiment of the present application, the shell 32 has a connection box 7 protruding from the outer wall of the shell 32, and the side of the connection box 7 facing the feeding device 2 has an outward flange 8, which is sealed and connected to the bottom of the feeding device 2 through the flange 8.

[0062] The shell 32 is provided with a connection box 7 protruding toward the outside, and the connection box 7 has an outward flange 8, which can be sealed and connected to the bottom of the feeding device 2 through the flange 8, thereby further ensuring that the rubber particles output from the feeding device 2 will not fall into the outside, avoiding the occurrence of rubber leakage, and further ensuring the stable output of the rubber particles.

[0063] As a preferred embodiment of the present application, the shell 32 is provided with an inlet connected to the connecting box 7 corresponding to the connecting box 7, so that the granules output from the output end of the feeding device 2 can enter the shell 32 through the connecting box 7 and the inlet.

[0064] like Figure 3 As shown, the connection box 7 is a hollow structure, and the connection box 7 has a through hole that passes through the upper and lower parts. The rubber particles output from the output end of the feeding device 2 flow out through the through hole of the connection box 7, so an inlet corresponding to the through hole is opened at a position on the shell 32 corresponding to the through hole of the connection box 7, so that the rubber particles can enter the interior of the shell 32 through the inlet.

[0065] As a preferred embodiment of the present application, one end of the shell 32 close to the material receiving device 4 is connected to a feeding shell 9 connected to the shell 32; the feeding shell 9 extends along the radial direction of the shell 32 and is inclined downward, and the end of the feeding shell 9 inclined downward has a feeding port 10 for outputting the rubber particles to the material receiving device 4.

[0066] like Figure 3As shown, after the rubber particles in the feeding device 2 enter the shell body 32, the rubber particles need to be output to the receiving device 4, so a feeding port 10 needs to be provided on the shell body 32. Since the telescopic component 41 and the receiving box 42 are both inclined, in order to allow the rubber particles output from the feeding port 10 to smoothly enter the receiving box 42, the end of the shell body 32 close to the receiving device 4 is connected to the feeding shell 9, which protrudes from the outer wall of the shell body 32 and extends a certain distance in an inclined downward direction. It is worth noting that in order to reduce the movement deviation of the rubber particles in the feeding shell 9 and enable them to smoothly slide onto the receiving box 42, the inclination angle of the feeding shell 9 is consistent with the inclination direction of the telescopic component 41 and the receiving box 42, thereby avoiding the inclination angle of the feeding shell 9 being greater than the inclination angle of the receiving box 42, resulting in an increase in acceleration when the rubber particles fall, resulting in collision between the rubber particles and the receiving box 42 and splashing, and avoiding the inclination angle of the feeding shell 9 being too small, resulting in the rubber particles not being able to smoothly enter the receiving box 42.

[0067] As a preferred embodiment of the present application, the glue spraying machine 11 is equipped with a laser distance measuring detector for detecting the height value of the glue surface inside the glue spraying machine 11 .

[0068] In order to further accurately know the height value of the glue surface in the glue sprayer 11, the number of times and the amount of glue particles are added are further set. After each time the top cover is opened, the laser rangefinder measures the height of the glue surface inside the glue sprayer 11 and feeds it back to the controller. The controller controls the speed of the motor 33 to control the output of the glue particles to ensure normal operation.

[0069] As a preferred embodiment of the present application, the feeding device 2 includes a feeding hopper, and a transparent window 5 is installed on the side of the feeding hopper, through which the interior of the feeding hopper can be observed.

[0070] like Figure 1 As shown, the feeding hopper of the feeding device 2 is in the shape of a funnel and has an inclined inner wall, which can further ensure that the rubber particles slide smoothly to the output end and enter the interior of the shell 32; in order to facilitate the observation of the inventory of rubber particles in the feeding hopper and determine whether to add them, transparent windows 5 are symmetrically arranged on the side of the feeding hopper. The transparent window 5 is made of transparent material, and the situation of the rubber particles inside the feeding hopper can be observed through the transparent window 5 to determine whether there is rubber. A photoelectric switch can also be arranged in the feeding hopper to provide an alarm whether there is a shortage of material in the feeding hopper.

[0071] As a preferred embodiment of the present application, a frame 6 is connected to one side of the base 1 , and a plurality of steps are provided on a side of the frame 6 facing away from the base 1 .

[0072] The frame 6 is disposed on one side of the base 1. Figure 1As shown, the purpose is to support the base 1 and further support the entire automatic glue pellet adding device. The purpose of arranging multiple steps on the frame 6 is to facilitate the staff to reach the upper hopper of the feeding device 2 of the automatic glue pellet adding device through the steps and add the glue pellets into the upper hopper.
