Technical Field

[0001] The utility model relates to the technical field of extruders, in particular to a feeding mechanism for the content of an extruder. Background Technique

[0002] Tablet presses are mainly used for the research of tablet processes in the pharmaceutical industry. Tablet presses are automatic continuous production equipment that presses granular materials into round, special-shaped tablets with a diameter not greater than 13 mm and tablets with words, symbols, and graphics. With the development of market demand, the scope of application of tablet presses is becoming wider and wider, and it is no longer simply limited to pressing Chinese and Western medicine tablets, but can also widely press health food, veterinary medicine tablets, chemical tablets, food tablets, etc.

[0003] When manufacturing toys similar to archaeological blind boxes, it is generally necessary to use a tablet press to extrude and form powder raw materials. At the same time, contents such as toys are added to the powder raw materials before extrusion. Since an extruder generally extrudes and forms multiple molds at the same time, it is time-consuming and laborious to manually place items in each forming cavity of the mold during the extrusion process. Therefore, a feeding mechanism for the content of an extruder is needed. Summary of the Invention

[0004] The purpose of the utility model is to provide a feeding mechanism for the content of an extruder to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A feeding mechanism for the content of an extruder, including a base fixed on one side of the middle mold and a slider horizontally slidably arranged on the top of the base through a first linear driving member. The first linear driving member is used to drive the slider to move towards or away from the middle mold. A plurality of placement holes are penetrated through the slider. A baffle is horizontally slidably arranged below the slider through a second linear driving member, and the baffle abuts against the bottom end of the slider to close the placement holes. The second linear driving member is used to drive the baffle to horizontally move relative to the slider.

[0006] Further, the baffle includes a bottom plate located below the slider and a side plate arranged at the top end of one side of the bottom plate. The side plate is located on the side of the slider away from the middle mold.

[0007] Further, mounting plates are fixed on both sides of the slider. The second linear driving member is fixed at one end of the mounting plate away from the middle mold, and the output end of the second linear driving member is fixed to the side plate. The length of the mounting plate is not less than the length of the baffle.

[0008] Further, second guiding strips are fixed to the bottom ends of the mounting plates, and the width of the second guiding strips is greater than the width of the mounting plates. One side of the second guiding strip is flush with the mounting plate, and the other side extends to the opposite sides of the two mounting plates. The baffle abuts against the top end of the second guiding strip, and both sides of the baffle abut against the two mounting plates respectively.

[0009] Further, a buffer protection mechanism is arranged on one side of the side plate close to the slider. The buffer protection mechanism includes a guiding bolt and a spring sleeved on the guiding bolt. A through hole matching the guiding bolt is penetrated through the side plate, and a nut is threadedly connected to one end of the guiding bolt penetrating through the through hole.

[0010] Further, first guiding strips for guiding and limiting the slider are arranged on both sides of the top end of the base.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] By arranging the base, the slider, the first linear driving member, the baffle and the second linear driving member, contents such as toys can be pre-placed in a plurality of placing holes on the slider. After the slider and the baffle are synchronously pushed to the top of the middle mold by the first linear driving member, and then the baffle is driven by the second linear driving member to be separated from the slider, the contents can be synchronously dropped into the forming cavity of the middle mold, so that articles can be placed into a plurality of forming cavities at the same time, the waiting time is reduced, and the working efficiency is improved;

[0013] By arranging the buffer protection mechanism, when the baffle is driven to move towards the side close to the slider, a buffer protection effect can be achieved. Description of the Drawings

[0021] Please refer to Figures 1-4 , an embodiment provided by the present utility model: a feeding mechanism for the content of an extruder, including a base 1 fixed on one side of the middle die 7 and a slider 2 horizontally slidably arranged on the top end of the base 1 through a first linear driving member 3. The first linear driving member 3 is used to drive the slider 2 to move towards or away from one side of the middle die 7. The first linear driving member 3 may specifically be an oil cylinder, horizontally installed on the side of the base 1 away from the middle die 7, and its output end is fixedly connected to the slider 2. A plurality of placement holes 201 are penetrated through the slider 2, and a plurality of forming cavities are penetrated through the middle die 7. The placement holes 201 correspond to the forming cavities on the middle die 7 one by one. A baffle 4 is horizontally slidably arranged below the slider 2 through a second linear driving member 5, and the baffle 4 abuts against the bottom end of the slider 2 to close the placement holes 201. The second linear driving member 5 is used to drive the baffle 4 to horizontally move relative to the slider 2. Specifically, the second linear driving member 5 may specifically be a cylinder, and the number is set to two, respectively installed on both sides in the width direction of the baffle 4.

[0022] Specifically, referring to the attached Figure 3 , the baffle 4 includes a bottom plate 401 located below the slider 2 and a side plate 402 integrally bent and provided at the top end of one side of the bottom plate 401. The side plate 402 is located on the side of the slider 2 away from the middle mold 7.

[0023] In this embodiment, long strip-shaped mounting plates 202 are fixed on both sides of the slider 2. One end of the mounting plate 202 is fixedly connected to the side wall of the slider 2, and the other end extends to the side of the slider 2 away from the middle mold 7. The second linear driving member 5 is fixed at the end of the mounting plate 202 away from the middle mold 7, and the output end of the second linear driving member 5 is fixedly connected to the side plate 402. The length of the mounting plate 202 is not less than the length of the baffle 4. When the bottom plate 401 is located below the slider 2, the second linear driving member 5 is in an extended state. When the second linear driving member 5 contracts, it can drive the baffle 4 to be completely separated from the slider 2, so that the item placed inside the placement hole 201 falls into the forming cavity of the middle mold 7 to achieve feeding.

[0024] Second guiding strips 203 are fixed at the bottom ends of the mounting plates 202, and the width of the second guiding strip 203 is greater than the width of the mounting plate 202. One side of the second guiding strip 203 is flush with the mounting plate 202, and the other side extends to the side where the two mounting plates 202 face each other. The baffle 4 abuts against the top end of the second guiding strip 203, and both sides of the baffle 4 are respectively abutted against the two mounting plates 202. When the baffle 4 slides below the slider 2, the mounting plates 202 and the second guiding strips 203 can play a role in guiding and limiting.

[0025] First guiding strips 101 for guiding and limiting the slider 2 are provided on both sides of the top end of the base 1. In this embodiment, the first guiding strips 101 abut against the outside of the second guiding strips 203. When the second guiding strips 203 and the slider 2 slide synchronously inside the first guiding strips 101, they can play a role in guiding and limiting the slider 2 and improve the stability of the movement of the slider 2.

[0026] Further, a buffer protection mechanism 6 is provided on one side of the side plate 402 close to the slider 2. The number of buffer protection mechanisms 6 is two, symmetrically installed on both sides of the side plate 402. The buffer protection mechanism 6 includes a guiding bolt 601 and a spring 603 sleeved on the guiding bolt 601. A through hole matching the guiding bolt 601 is provided through the side plate 402, and one end of the guiding bolt 601 passes through the through hole and is threadedly connected with a nut 602. One end of the spring 603 abuts against the nut of the guiding bolt 601, and the other end abuts against the side plate 402. When the second linear driving member 5 drives the baffle 4 to move towards the side close to the slider 2, the nut of the guiding bolt 601 abuts against the side plate 402 in advance and compresses the spring 603 backward, playing a role of buffer protection to prevent the side plate 402 from directly hitting the slider 2. In this embodiment, the output end of the second linear driving member 5 passes through the side plate 402, and then the side plate 402 is clamped and fixed in the middle by two nuts. The buffer protection mechanism 6 can also prevent the output end of the second linear driving member 5 from directly hitting the slider 2.

[0027] Working principle: Figure 4 This is an assembly schematic diagram of the present application. The base 1 is installed on one side of the middle mold 7, and the upper mold 8 and the lower mold 9 are respectively located on the upper and lower sides of the middle mold 7. The upper mold 8 and the lower mold 9 are driven by an oil cylinder to move towards or away from the middle mold 7 to perform mold closing and extrusion molding or mold opening and discharging. Its specific structure is the prior art and will not be elaborated here. During work, the slider 2 and the baffle 4 are located on one side of the middle mold 7, and the baffle 4 is located below the slider 2 to block the bottom end of the placement hole 201. Toys and other contents are added into the placement hole 201. At the same time, powder raw materials are added into each forming cavity of the middle mold 7. Then, the first linear driving member 3 is driven to extend, pushing the slider 2 and the baffle 4 to move synchronously to the directly above the middle mold 7. The placement hole 201 corresponds to each forming cavity of the middle mold 7. The second linear driving member 5 contracts to drive the baffle 4 to separate from the slider 2, so that the items inside the placement hole 201 fall into each forming cavity of the middle mold 7. The first linear driving member 3 drives the slider 2 and the baffle 4 to reset. At the same time, the second linear driving member 5 drives the baffle 4 to move below the slider 2, and powder raw materials are continuously added into the middle mold 7 to wrap the contents inside. Finally, the upper mold 8 and the lower mold 9 are closed to extrude and form the raw materials.
