Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of canning equipment, and particularly relates to a rotary material pressing mechanism and a material pressing device. BACKGROUND

[0002] In the field of canned food, long-shaped foods such as pickled cucumbers are often processed. When filling, such foods are arranged in disorder due to uneven distribution, which occupies a large space in the container (such as a can or a bottle), thereby causing insufficient filling capacity. In order to solve this problem, the food in the container is currently manually combed by workers to make it compact and orderly arranged, and then a second filling is carried out, so that the food capacity in the container can meet the standard. However, this operation mode is not only backward and cannot adapt to the flow line operation mode, but also causes high labor cost, and the production efficiency is difficult to improve.

[0003] Therefore, it is necessary to design a material pressing device which can automatically compact the long-shaped food in the container to ensure the filling capacity, and can greatly reduce the production cost and improve the production efficiency to overcome the current defects. SUMMARY

[0004] The purpose of the present application is to solve the technical problems of manual compaction of long-shaped food, such as complicated process, low efficiency, high cost and inability to adapt to flow line operation mode, and to provide a rotary material pressing mechanism and a material pressing device to solve the above technical problems.

[0005] To solve the above technical problems, the technical scheme adopted by the present application is as follows: On the one hand, a rotary material pressing mechanism is provided, comprising: a turntable one which rotates under the drive of a driving part through a main shaft at the center; at least one rotating part which is arranged at the outer periphery close to one side of the turntable one through a bearing part and revolves with the turntable one; an end of the rotating part away from the turntable one is detachably connected with a material pressing end head extending downward.

[0006] As a further improvement of the present application, the end of the rotating part away from the turntable one is provided with a supporting block, and the supporting block is provided with a positioning hole; a screw rod provided on the material pressing end head is inserted into the positioning hole and is tightly connected with each other through a nut.

[0007] As a further improvement of the present application, the positioning hole is a long hole corresponding to the axial direction of the rotating part.

[0008] As a further improvement of the present application, an auxiliary positioning assembly is further included; the auxiliary positioning assembly comprises a support arranged on the other side of the first rotating disc, and the support and the first rotating disc are provided with a second rotating disc corresponding to the eccentricity of the first rotating disc, the second rotating disc is rotatable with its center on the support under the limitation of a plurality of fixed pulleys arranged on the support, and the second rotating disc is movably connected with the rotating member through a joint component.

[0009] As a further improvement of the present application, the joint component comprises a stand arranged on the side of the second rotating disc facing the first rotating disc and close to the rotating member, the stand is provided with a swing arm movably connected with one end of the stand, and the other end of the swing arm is movably inserted into a socket of a swing seat fixed on the rotating member.

[0010] As a further improvement of the present application, a plurality of limiting long holes for limiting the fixed pulleys are arranged on the support, and the length direction of the limiting long holes is consistent with the radial direction of the support.

[0011] On the other hand, a material pressing device is provided, which comprises a conveying belt, one side of the conveying belt is provided with a guardrail, and the other side is provided with a spiral feeding rod, the spiral feeding rod is drivingly connected with a driving component. The material pressing device further comprises the rotary material pressing mechanism as described above, wherein the pressing end of the rotary material pressing mechanism corresponds to the upper and lower positions of the container, and the pressing end extends into the container when the pressing end is in the low position.

[0012] As a further improvement of the present application, the spacing between the spiral groove of the spiral feeding rod and the guardrail is adapted to the transverse diameter of the container.

[0013] Due to the adoption of the above technical solutions, the present application has the following advantages: Since the pressing end of one end of the rotating member extends downward, and the rotating member is rotatably connected with the first rotating disc through a bearing component, the pressing end will naturally assume a downward posture under the influence of gravity. With the rotation of the first rotating disc, the pressing end will rotate together (i.e., the pressing end performs revolution).

[0014] At the same time, since the pressing end is rotatably connected with the first rotating disc through the bearing component, the pressing end does not perform rotation while performing revolution, i.e., the pressing end always performs revolution in a downward posture. When the pressing end rotates to the low position, it will be pressed into the container (such as a jar or a bottle) to compact the long strip-shaped material, facilitating the subsequent addition of material into the container.

[0015] The cumbersome manual pressing process of the material is omitted, not only the work efficiency is doubled, but also the labor cost is greatly saved, and the product has market competitiveness. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and advantages of the present application more clear and obvious, the following will be described through the accompanying drawings and specific embodiments. Figure 1 to Figure 11and examples, the present application will be further explained. It should be understood, however, that the specific examples, while indicating preferred embodiments of the application, are given by way of illustration only and are not intended to limit the scope of the application. Furthermore, in the following description, well-known structures and techniques have not been described in order to avoid obscuring the concepts of the present application.

[0019] Embodiment One The purpose of this embodiment is to provide a rotary material pressing mechanism which can achieve the effect of material pressing on the basis of simple structure.

[0020] Reference Figure 1 Specifically includes: the rotating disc 110 rotates through the main shaft 1101 at the center under the drive of the drive part 300. It should be noted that its rotation direction and rotation speed need to be adapted to the conveying direction of the conveyor belt 201 in order to facilitate subsequent material pressing operation.

[0021] There is also at least one rotating part 120 (in practice, four rotating parts 120 are uniformly arranged, such as a rotating shaft, which can also be a rotating ring or a rotating disc), which is arranged at the outer periphery close to one side of the rotating disc 110 and revolves with the rotating disc 110 through the bearing part 1102 (such as a ball bearing).

[0022] That is, the rotating part 120 is arranged at one side of the rotating disc 110 close to the outer periphery, which facilitates the revolving of the rotating part 120 in a larger range, thereby adapting to the spacing between every two adjacent containers. Moreover, its connection relationship with the rotating disc 110 is a rotating connection, that is, the rotating disc 110 rotates to drive it to revolve, but it does not rotate itself in the axial direction under the action of the bearing part 1102.

[0023] The end of the rotating part 120 away from the rotating disc 110 is detachably connected with a material pressing end 1201 extending downward, which can be used to compact the material. Because the material pressing end is arranged to extend downward, and under the action of the bearing part 1102, the material pressing end 1201 will always revolve in a downward posture under the action of gravity and does not rotate itself.

[0024] When the material pressing end 1201 gradually revolves to the low position, it will correspond to the container below, thereby gradually extending into the container to compact the material. With the continuous conveying of the container on the conveyor belt and the rotation of the rotating disc 110, the material pressing end will gradually separate from the container, thereby reciprocating to realize the rotary material pressing process. That is, in this process, the downward posture of the material pressing end 1201 can better extend into the container.

[0025] It should be noted that the structure adopted in the present embodiment is relatively simple and has more advantages in cost. However, because the rotating part 120 and the bearing part 1102 are connected in a free manner, in the process of compacting the material, the rotating part 120 may have a certain axial rotation due to factors such as deviation of the pressing direction caused by irregular accumulation of the material in the container, thereby causing the pressing end 1201 to swing, and finally causing the container to tilt and fall. Therefore, on the basis of the present embodiment, the container on the conveying belt 201 needs to be limited (such as a limiting frame or a limiting groove) to ensure that the container remains fixed in position during conveying, thereby avoiding the tilting and falling of the container caused by the free connection of the rotating part 120 during pressing. However, this does not negate the effect of the pressing end 1201 in compacting the material in the container.

[0026] In actual use, because the specifications and sizes of the containers are different, in order to better adapt to containers of different heights and diameters, a support block 1202 is arranged at one end of the rotating part 120 away from the rotating disc one 110, and the two are fixedly connected; the support block 1202 is provided with a positioning hole 1203. Moreover, the positioning hole 1203 is an elongated hole corresponding to the axial direction of the rotating part 120.

[0027] The screw rod 1204 arranged on the pressing end 1201 is inserted into the positioning hole 1203 and is tightly connected with the positioning hole 1203 through the nut 1205, so as to achieve the purpose of dismounting and connecting. By adjusting the screw rod 1204 and the nut 1205, the relative position of the pressing end 1201 in the height direction and the horizontal direction is realized, so as to adapt to containers of different specifications and sizes.

[0028] Embodiment Two Reference Figures 2 to 9 The purpose of the present embodiment is to further improve the stability of the pressing process on the basis of Embodiment One, to ensure that the posture of the pressing end 1201 does not change, and to avoid the inconvenience of limiting the position of the container through other components.

[0029] Specifically, it includes an auxiliary positioning assembly that can limit the rotating part 120 so that it does not rotate in the axial direction (i.e., spin), thereby ensuring that the posture of the pressing end 1201 remains downward at all times.

[0030] The auxiliary positioning assembly includes a support 130 arranged on the other side of the rotating disc one, and the support 130 and the rotating disc one 110 are provided with a rotating disc two 1301 that corresponds to the rotating disc one 110 in an eccentric manner, and the rotating disc two 1301 can rotate around its center under the limitation of a plurality of fixed pulleys 1302 arranged on the support 130. That is, the center of the rotating disc two 1301 and the center of the rotating disc one 110 correspond to each other in an eccentric manner. Moreover, the rotating disc two 1301 can also rotate around its own center under the action of the fixed pulleys 1302.

[0031] The rotating disc two 1301 is movably connected with the rotating member 120 through a joint component. When the rotating disc one 110 drives the rotating member 120 to revolve, the rotating disc two 1301 can be driven to revolve around its own center under the action of the joint component.

[0032] The purpose of this structure is to add an auxiliary structure for limiting the rotating member 120 on the basis of the first embodiment, so that the pressing end head 1201 will not swing even if it is affected by uneven material arrangement when pressing.

[0033] Specifically, in the structure of the first embodiment, the rotating member 120 and the bearing member 1102 are freely connected. That is, under the influence of the extension direction of the pressing end head 1201 and gravity, the rotating member 120 does not rotate when revolving. Although the posture of the pressing end head 1201 is always consistent when the rotating disc one 110 rotates, this posture is not limited. That is, it will swing freely when pressing due to the influence of uneven material arrangement. By setting the joint component, the rotating member 120 can be limited, so that it is limited by a certain external force when revolving, thereby keeping the true posture consistent.

[0034] The influence of the uneven material arrangement in the container on the non-vertical pressing force is far less than the limiting effect of the auxiliary positioning assembly on the rotating member 120, which ultimately avoids the deficiency that the rotating member 120 rotates due to uneven material arrangement, and also saves the inconvenience of additionally limiting the container.

[0035] The joint component will be further described below. The joint component includes a stand 1401 arranged on the side of the rotating disc two 1301 facing the rotating disc one 110 and close to the rotating member 120, and the two are fixedly connected. The stand 1401 is provided with a swing arm 1402 movably connected with one end thereof. As can be seen from the figure, the swing arm 1402 is connected to the stand 1401 through a connecting ring, and the two are in movable connection. The other end of the swing arm 1402 is movably connected with a plug hole 1404 of a swing seat 1403 fixedly connected to the rotating member 120, and the two are also in movable connection.

[0036] Reference Figure 5 and Figure 6 and Figure 8, the rotating part 120 does not rotate due to the influence of the extension direction of the pressure material end head 1201 and gravity. The swing seat 1403 is fixedly connected with the rotating part 120, and does not rotate. The swing arm 1402 is movably inserted into the insertion hole 1404 of the swing seat 1403, that is, the swing arm 1402 can move axially in the insertion hole 1404. The swing arm 1402 is movably sleeved on the stand 1401 through the connecting ring. With the continuous revolution of the rotating part 120, one end of the swing arm 1402 performs reciprocating piston action in the insertion hole 1404, thereby offsetting part of the force generated by the revolution. Meanwhile, the other end of the swing arm 1402 is movably sleeved on the stand 1401 through the connecting ring, which can also offset part of the force generated by the revolution (see Figure 8 ). The stand 1401 drives the rotating disc two 1301 to passively rotate on the fixed pulley 1302, thereby offsetting the force generated by the revolution for the third time, and finally enabling the rotating part 120 to be limited by the limiting force generated by the multiple movable connections.

[0037] When the material is pressed, the offset force of the downward pressure deviating from the vertical direction due to uneven arrangement of the material is far less than the limiting force of the joint part on the rotating part 120, thereby ensuring that the pressure material end head 1201 performs the downward pressing action in the vertical direction when it revolves to the low position.

[0038] As a further improvement of the present application, the support 130 is provided with a plurality of limiting long holes 1303 for limiting the fixed pulley 1302, the length direction of the limiting long holes 1303 is consistent with the radial direction of the support 130, and different degrees of deviation and positions can be adjusted by adjusting the different positions of the fixed pulley 1302 in the limiting long holes 1303.

[0039] Embodiment three The same parts of the present embodiment as those of the first and second embodiments will not be described again.

[0040] Reference Figure 10 and Figure 11 The purpose of the present embodiment is to provide a material pressing device which can compact the material in the containers on the assembly line and save the inconvenience of manual operation.

[0041] The conveying belt 201 for conveying the containers is provided with a guardrail 202 on one side for limiting the containers in one direction. Of course, the relative position of the guardrail can also be adjusted to adapt to containers of different specifications. The other side is provided with a spiral feeding rod 203 which can limit the other side of the containers and also can arrange the containers which are close to each other at equal intervals in a head-to-tail interval manner. The spiral feeding rod 203 is drivingly connected with the driving part 300. The function of the spiral feeding rod 203 is to separate the containers which are close to each other, so that each adjacent container is arranged at equal intervals, thereby keeping the height direction of the pressure material end head 1201 in correspondence with the up and down.

[0042] Also included is the rotary pressure mechanism of embodiment one or embodiment two, wherein the pressure head 1201 corresponds to the port of the container up and down, and the pressure head 1201 extends into the container when revolving to the low position, thereby pressing the strip-shaped material in the container. After pressing, continue to fill the material to meet the predetermined capacity.

[0043] As a further improvement of the present application, the distance between the spiral groove of the spiral feeding rod 203 and the guardrail 202 is adapted to the transverse diameter of the container. This structure is to adapt to the structure of embodiment one, so as to have the clamping effect of limiting the container in the lateral direction, preventing the container from tilting and falling when the vertical downward force is deviated.

[0044] In addition, it should be noted that the driving part 300 in each of the above embodiments can be a plurality of driving parts (such as driving motors) independent of each other, or various transmission mechanisms driven by one driving part. For example, Figure 10 and Figure 11 As shown in the above two embodiments, the driving part is a driving motor, the driving end of which is in transmission connection with the speed reducer, one driving end of the speed reducer drives the main shaft 1101 to rotate through a chain (or other transmission part); the other driving end of the speed reducer drives the screw feeding rod 203 through a transmission rod (or other transmission part). In this way, one driving part can save cost, and it is also convenient for the synchronous coordination and matching between the main shaft 1101 and the screw feeding rod 203.

[0045] Due to the adoption of the above technical solutions, the present application has the following advantages: Because the pressure head at one end of the rotating part extends downward, and the rotating part is in rotary connection with the turntable one through the bearing part, the pressure head will naturally assume a downward posture under the influence of gravity. With the rotation of the turntable one, the pressure head will rotate together (i.e. the pressure head revolves).

[0046] At the same time, the pressure head is in rotary connection with the turntable one through the bearing part, and it does not rotate while revolving, i.e. the pressure head always revolves in a downward posture. When the pressure head rotates to the low position, it will press into the container (such as a jar or a bottle) to compact the long strip-shaped material, facilitating the subsequent addition of material to the container.

[0047] The tedious manual pressing of the material is omitted, not only the work efficiency is doubled, but also the labor cost is greatly saved, and the product has market competitiveness.
