The unloader is self-positioning, has a simplified structure, and prevents saggers from falling and being damaged.

Description

Technical Field

[0001] The invention belongs to the technical field of supporting equipment for electronic kilns, and in particular relates to a sagger unloader for an electronic kiln with self-positioning and self-positioning functions and free of clamping. Background Art

[0002] The aforementioned electronic kiln is mainly used for but not limited to the firing of electronic powder materials. Typical examples of electronic powder materials can be found in the "Automatic unloading device for saggers used in electronic powder material production lines" recommended by CN103512368B and the "Automatic unloading device for saggers with horizontal correction function for the flip disk roller" provided by CN108955270A. By reading the aforementioned patent documents which are not limited to the examples, it can be known that the aforementioned electronic powder materials are contained in a sagger and are introduced into the furnace from the furnace entrance of the electronic kiln by the sagger, and then pass through the preheating zone (also called "preheating section"), the heating zone (also called "heating section"), the constant temperature zone (also called "constant temperature section") and the cooling zone (also called "cooling section") of the furnace in sequence, and then are discharged from the discharge port of the furnace. After being discharged, they are usually crushed by an automatic crushing device such as the "electronic powder material crusher" introduced in CN103521314B, and then transported by a conveying device to the work station where the sagger unloader (also called "sagger automatic unloading device") is located to unload or pour out the electronic powder materials in the sagger.

[0003] Although the "automatic sagger unloading device with the function of horizontal correction of the flip disk roller" provided by the aforementioned CN108955270A can objectively reflect the technical effects recorded in paragraph 0019 of its specification, it has at least the following two shortcomings: First, since a group of flip disk rollers corresponding to the upper and lower connecting support rods of the flip disk and rotatably supported between the front and rear flip disks in an interval state are used in the structural system of the sagger unloading mechanism, the group of flip disk rollers are driven to move by the flip disk roller driving mechanism. Therefore, the aforementioned group of flip disk rollers need to be rotatably supported between the front and rear flip disks with the help of bearings. However, due to the dust in the working chamber of the unloading mechanism, the bearings may be stuck or even stuck. When the bearings of one or several flip disk rollers in a group of flip disk rollers are stuck or even stuck, then a group of flip disk rollers will be pulled out of the sagger entrance. In the process of transporting the saggers to the space between the front and rear turning discs, problems such as slipping, poor transport stability, or even incomplete transport will inevitably occur. Therefore, a group of turning disc rollers are set in the area between the front and rear turning discs. Although the saggers can be transported to the right place under normal circumstances, the probability of the bearings getting stuck or even stuck is very high, and frequent inspection and replacement of bearings are required. This increases the maintenance workload and use cost of the equipment on the one hand, and increases the workload of equipment maintenance personnel on the other hand. On the other hand, if it is not discovered and handled in time, it will cause problems such as production stoppage. Secondly, since it is necessary to use the front side clamping mechanism of the sagger and the rear side clamping mechanism of the sagger (also known as "clamping mechanism"), the structure is very complicated, and once the front side and / or rear side clamping mechanism of the sagger fails or the action coordination of the two is inconsistent, it is very easy to cause the sagger to fall or even be damaged. In view of the above-mentioned shortcomings, it is necessary to improve them. The technical solution to be introduced below is produced in this context. Summary of the Invention

The pair of right opening and closing door guide rails 25d are respectively located on the two sides of the sagger entrance port 25 b on both sides; the aforementioned unloading box left opening and closing door 21 is located between a pair of left opening and closing door guide rails 25c and slides up and down with a pair of left opening and closing door guide rails 25c, and the aforementioned unloading box right opening and closing door 22 is located between a pair of right opening and closing door guide rails 25d and slides up and down with a pair of right opening and closing door guide rails 25d; the aforementioned opening and closing door drive mechanism 23 includes a gantry 231, a left opening and closing door lifting cylinder 232 and a right opening and closing door lifting cylinder 233, and the gantry 231 is shaped like The left lifting cylinder 232 of the door opening and closing door is in a longitudinal cantilever state and is hinged to the left end top of the gantry 231 by means of the left connecting arm plate 2322. The left lifting cylinder column 2321 of the door opening and closing door left lifting cylinder 232 faces downward and is hinged to the left door opening and closing door cylinder column hinge ear 211 fixed to the upper center position of the left side surface of the left door opening and closing door 21 of the aforementioned discharge box through the left lifting cylinder column hinge pin 23211. The right lifting cylinder 233 of the door opening and closing door is in a longitudinal cantilever state and is hinged to the left end top of the gantry 231 by means of the left connecting arm plate 2322. The right lifting cylinder 2331 of the opening and closing door right lifting cylinder 233 faces downward and is hinged to the right opening and closing door cylinder column hinge ear 221 fixed at the upper center position of the right side surface of the right opening and closing door 22 of the aforementioned discharge box through the right lifting cylinder column hinge pin 23311; at least one pair of air filter elements 25e are provided on the top box wall of the discharge box 2 for communicating the discharge box cavity 24b with the outside world.

[0030] In this embodiment, the aforementioned left and right lifting cylinders 232 and 233 for the door opening and closing are pneumatic cylinders and operate synchronously. Taking the operation of the left lifting cylinder 232 as an example, when the left lifting cylinder column 2321 of the door opening and closing moves upward, i.e., retracts into the cylinder body, the left lifting cylinder column 2321 drives the left door 21 of the discharge box to slide upward (i.e., rise) along the pair of left door guide rails 25c, and vice versa. Since the operating principle of the right lifting cylinder 233 is the same as that of the left lifting cylinder 232, the applicant will not elaborate on it. When the left and right opening and closing doors 21 and 22 of the unloading box are both in an upward displacement and the empty saccade outlet 25a and the inlet 25b of the saccade to be unloaded are unsealed, the saccade 10 to be unloaded, which is fed in by the saccade conveying mechanism 3 and then pushed into the saccade self-limiting unloading cage 5 located in the saccade unloading box cavity 24b through the inlet 25b of the saccade to be unloaded by the saccade pushing mechanism 7, is driven out of the saccade self-limiting unloading cage 5 through the empty saccade outlet 25a. It can be seen from this that the saccade self-limiting unloading cage 5 can only accommodate one saccade.

[0031] As a preferred solution, the upper end and lower end of a pair of left opening and closing door guide rails 25c can be hinged to the left box wall of the discharge box through a left opening and closing door guide rail hinge ear (also known as a hinge arm), and similarly, the upper end and lower end of a pair of right opening and closing door guide rails 25d can be hinged to the right box wall of the discharge box through a right opening and closing door guide rail hinge ear (also known as a hinge arm). The advantage of this structural design is that when the left and right opening and closing doors 21 and 22 of the discharge box are closed, the left and right opening and closing doors 21 and 22 of the discharge box can respectively play a good sealing role on the empty sagger row outlet 25a and the sagger entrance 25b to be discharged.

[0033] Depend on Figures 1 to 3 As shown, the aforementioned unloading sack pushing mechanism 7 is arranged between the aforementioned left beam 313 of the bracket and the upward side of the right beam 314 of the bracket; the aforementioned unloading sack lifting mechanism 8 is located at the right end between the aforementioned front and rear beams 311 and 312 of the bracket; the front one of the aforementioned pair of unloading sack travel channel opening and closing mechanisms 9 is connected to the middle part of the longitudinal direction of the aforementioned front guide baffle support beam 32 of the unloading sack toward the rear guide baffle support beam 33 of the unloading sack, and the rear one of the pair of unloading sack travel channel opening and closing mechanisms 9 is connected to the middle part of the longitudinal direction of the rear guide baffle support beam 33 of the unloading sack toward the front guide baffle support beam 32 of the unloading sack.

[0034] The functions of the aforementioned discharge box opening and closing door opening signal transmitter 323 and the discharge box opening and closing door opening signal receiver 333 are to detect whether there is a sagger 10 on the right side of the right opening and closing door 22 of the discharge box. If so, the left side of the sagger 10 here will touch the sagger blocking roller 222 arranged at the lower right side of the right opening and closing door 22 of the discharge box, and the sagger 10 to be unloaded will block the space (signal path) between the discharge box opening and closing door opening signal transmitter 323 and the discharge box opening and closing door opening signal receiver 333, and the discharge box opening and closing door opening signal receiver 333 will feed back the signal to the electrical controller, and the electrical controller will give a signal to the aforementioned opening and closing door left and right lifting cylinders 232 and 233 to open and close the material. The left and right door lifting cylinders 232 and 233 work to lift the left and right opening and closing doors 21 and 22 of the unloading box upwards to open the door. The passage between the sagger entrance 25b to be unloaded and the empty sagger row outlet 25a is communicated, and the sagger 10 to be unloaded can be pushed into the sagger unloading box cavity 24b by the sagger pushing mechanism 7, or more precisely, into the sagger self-limiting unloading cage 5. At the same time, the empty sagger still in the sagger self-limiting unloading cage 5 that has completed unloading is expelled from the cage cavity of the sagger self-limiting unloading cage 5 from the empty sagger row outlet 25a by the sagger 10 to be unloaded that has been pushed into the sagger self-limiting unloading cage 5. That is, the empty sagger is replaced by the sagger 10 to be unloaded that has entered the sagger self-limiting unloading cage 5. The aforementioned discharge box door opening signal transmitter 323 and discharge box door opening signal receiver 333 are respectively a signal transmitting element and a signal receiving element and are electrically connected to the electrical controller. Under normal circumstances, the potential difference between the two sides is equal (it can also be said that the potential difference between the two sides is zero). However, when blocked by the sagger 10, the potential difference between the two sides becomes unequal, and a signal is sent to the electrical controller.

[0035] Since the working mechanism of the channel opening and closing signal transmitter 322 and the channel opening and closing signal receiver 332 mentioned above is the same as that of the unloading box opening and closing door opening signal transmitter 323 and the unloading box opening and closing door opening signal receiver 333, the only difference is that the signal is given to the electrical controller, and the electrical controller controls a pair of unloading sagger travel channel opening and closing mechanisms 9.

[0036] After the electrical controller sends a signal to the unloading sagger conveying drive motor 341 of the unloading sagger conveying drive device 34 of the structural system of the unloading sagger conveying mechanism 3, the unloading sagger conveying drive motor 341 starts working and drives the unloading sagger conveying drive reduction box 342, and the unloading sagger conveying drive reduction box shaft drives the unloading sagger conveying driving sprocket shaft 343, and the rotation of the unloading sagger conveying driving sprocket shaft 343 simultaneously drives the front and rear conveying chain driving sprockets 36. a, 36b, so that the front conveying chain 35a of the sagger to be unloaded moves around the front conveying chain driving sprocket 36a and the front conveying chain driven sprocket 37, and at the same time, the rear conveying chain 35b of the sagger to be unloaded moves around the rear conveying chain driving sprocket 36b and the rear conveying chain driven sprocket 38, thereby rhythmically conveying the sagger 10 to be unloaded, which is input or pushed by the conveying device at the previous process such as the automatic crushing station (see CN103521314B), toward the sagger unloading box 2.
