Description

Technical Field

[0001] The utility model relates to the technical field of trimming of pulp tableware, in particular to a multi-station reciprocating trimming device. Background Art

[0002] Pulp tableware is a kind of disposable tableware mainly made of pulp and formed by a molding process. During the molding process of pulp tableware, redundant pulp edges or irregular shapes may be formed at the edges. Through a trimming device, these irregular parts can be removed, making the edges of the tableware neat and improving the appearance quality of the product;

[0003] At present, most trimming devices are generally equipped with a single station for conveying tableware, resulting in the trimming device being able to place another tableware only after one tableware has been trimmed. The efficiency of trimming and conveying tableware is poor. Trimming devices also generally use the shearing force generated when a circular cutter extrudes the tableware for trimming. However, when trimming in this way, the edge materials often adhere to the pulp tableware due to the stickiness generated by friction, which easily affects the trimming quality of the tableware. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a multi-station reciprocating trimming device to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A multi-station reciprocating trimming device includes a machine case. A transmission shaft is rotatably connected to the top of the machine case. A plurality of support rods are rotatably connected to the outside of the transmission shaft at equal angles in a circular shape. A defective gear disk that is intermittently engaged and driven with the support rods is fixed to the top surface of the machine case. One end of the support rod is fixed with a conveying mechanism. The conveying mechanism includes a receiving disk. A circular groove is formed on the top surface of the receiving disk. A U-shaped frame is fixed to the outside of the machine case. A trimming mechanism is fixed to the top of the U-shaped frame. The trimming mechanism includes a cylinder fixedly connected to the U-shaped frame. The output end of the cylinder is fixed with a downward pressing rubber block. A circular knife rotatably sleeved on the outside of the top of the downward pressing rubber block is rotatably connected to the output end of the cylinder.

[0007] Furthermore: A storage box is fixed to the outside of the machine case. A plurality of arc-shaped rods are evenly fixed to the inside of the storage box.

[0008] Furthermore: The output end of the cylinder is rotatably connected to a fixed ring fixedly connected to the circular knife. A motor two for driving the fixed ring to rotate is fixed to the output end of the cylinder.

[0009] Furthermore, a plurality of blades are fixed at equal angles in a ring shape on the outer side of the ring cutter, a ring block is rotatably connected to the top surface of the receiving plate, and a plurality of rectangular grooves are opened at equal angles in a ring shape on the top surface of the ring block.

[0010] Furthermore, the rectangular groove is communicated with the annular groove, and an annular baffle is fixed on the outer side of the receiving plate.

[0011] Furthermore, the support rod includes a connecting shaft rotatably connected to the transmission shaft, one end of the connecting shaft is fixed with a connecting plate fixedly connected to the receiving disk, and the other end of the connecting shaft is fixed with a transmission bevel gear meshing with the incomplete gear disk.

[0012] Furthermore, an arc-shaped block against which a connecting plate slides is fixed on the top surface of the chassis, and a motor for driving a transmission shaft to rotate is fixed inside the chassis.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. Multiple support rods are connected by evenly rotating on the outside of the transmission shaft, and a receiving plate is fixed at one end of each support rod. When a support plate moves to the bottom of the trimming mechanism for trimming, tableware can be placed on the spare receiving plate. After the first tableware is trimmed, the spare receiving plate directly transfers another tableware to the bottom of the trimming mechanism, thereby realizing multi-station circular conveying of tableware for trimming, which is beneficial to improving the efficiency of tableware trimming and conveying.

[0015] 2. A bevel gear that intermittently meshes with the incomplete gear plate is fixed on the outside of the support rod. After the support rod carries the trimmed tableware through the position of the teeth on the incomplete gear plate, the support rod rotates 360 degrees with the receiving plate. During the rotation of the receiving plate, the trimmed tableware can be stored in the storage box, which facilitates the combination of tableware transportation, trimming and unloading, thereby improving the overall efficiency of the trimming equipment.

[0016] 3. The output end of the cylinder brings the downward pressure rubber block to limit and fix the tableware bowl inside the receiving plate. The output end of the cylinder continues to move downward to compress the downward pressure rubber block, and the ring knife presses down to cut the edge material of the tableware bowl. Then the second motor drives the ring knife to rotate slightly back and forth, so that the edge material can be completely separated from the tableware bowl. To a certain extent, it solves the problem that the existing extrusion cutting will cause the edge material to stick to the pulp tableware due to friction. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1

[0026] Please refer to Figure 1-5 , in the embodiment of the present utility model, a multi-station reciprocating trimming device includes a chassis 100. A transmission shaft 110 is rotatably connected to the top of the chassis 100. A plurality of support rods 200 are rotatably connected to the outside of the transmission shaft 110 at equal angles in a circular shape. An incomplete gear disk 120 that meshes and drives intermittently with the support rods 200 is fixed on the top surface of the chassis 100. One end of the support rod 200 is fixed with a conveying mechanism 300. The conveying mechanism 300 includes a receiving tray 310. An annular groove 320 is opened on the top surface of the receiving tray 310. A C-shaped frame 140 is fixed on the outside of the chassis 100. A trimming mechanism 400 is fixed on the top of the C-shaped frame 140. The trimming mechanism 400 includes a cylinder 410 fixedly connected to the C-shaped frame 140. A downward pressing rubber block 420 is fixed to the output end of the cylinder 410. A circular knife 430 rotatably sleeved on the outside of the top of the downward pressing rubber block 420 and rotatably connected to the output end of the cylinder 410.

[0027] Specifically, a plurality of receiving plates 310 that can be switched and rotated are arranged below the annular knife 430, and each receiving plate 310 can be placed on the cutlery bowl to be trimmed, so that after the trimming of one cutlery bowl is completed, another receiving plate 310 can be connected to transport another cutlery bowl for trimming, which is beneficial to improving the efficiency of cutlery trimming and transportation, and the cutlery bowl is limited and fixed inside the receiving plate 310 by the output end of the cylinder 410 with the downward pressure rubber block 420, and the output end of the cylinder 410 continues to move downward to compress the downward pressure rubber block 420, and the annular knife 430 presses down to cut the edge material of the cutlery bowl, and the motor 2 412 drives the annular knife 430 to rotate back and forth slightly, so that the edge material can be completely separated from the cutlery bowl, which to a certain extent solves the problem that the edge material will stick to the pulp cutlery due to friction due to extrusion trimming.

[0028] like Figure 4 As shown, in this embodiment, the output end of the cylinder 410 is rotatably connected to a fixed ring 411 fixedly connected to the ring knife 430, and the output end of the cylinder 410 is fixed with a motor 2 412 for driving the fixed ring 411 to rotate.

[0029] In this embodiment, a plurality of support rods 200 fixedly connected to a fixed ring 411 are fixed to the output end of the cylinder 410, and a gear ring rotatably sleeved on the output end of the cylinder 410 is fixed above the support rods 200. The driving gear at the output end of the motor 2 412 drives the gear ring to rotate, causing the fixed ring 411 to rotate with the ring knife 430, so that the cut edge materials can be effectively separated from the tableware.

[0030] like Figure 4 and Figure 5 As shown, in this embodiment, a plurality of blades 431 are fixed at equal angles in a ring shape on the outer side of the ring knife 430, an annular block 330 is rotatably connected to the top surface of the receiving plate 310, a plurality of rectangular grooves 331 are opened at equal angles in a ring shape on the top surface of the annular block 330, the rectangular grooves 331 are connected to the annular grooves 320, and an annular baffle 311 is fixed to the outer side of the receiving plate 310.

[0031] In this embodiment, when the ring knife 430 is pressed down to cut the edge, the blade 431 is pressed down to cut the edge material and extend into the rectangular groove 331. The ring knife 430 is pressed down into the annular groove 320, and the blade 431 can cut the edge material into small pieces, which is convenient for dropping to the inner bottom of the storage box 150 later. The annular block 330 can rotate on the receiving plate 310 to facilitate the rotation of the ring knife 430 with the blade 431. The blade 431 can rotate with the annular block 330 along with the ring knife 430. Before the cylinder 410 drives the ring knife 430 and the blade 431 downward for cutting, the motor 2 412 can be used to rotate the ring knife 430 in advance so that the blade 431 can be arranged above the rectangular groove 331, which is convenient for the blade 431 to be inserted into the rectangular groove 331 later, so as to achieve the effect of fully cutting off the edge material. The annular baffle 311 can prevent the edge material from spilling to the outside of the receiving plate 310.

[0032] like Figure 3 As shown, in this embodiment, the support rod 200 includes a connecting shaft 210 rotatably connected to the transmission shaft 110, one end of the connecting shaft 210 is fixed with a connecting plate 220 fixedly connected to the receiving plate 310, the other end of the connecting shaft 210 is fixed with a transmission bevel gear 230 meshing with the incomplete gear plate 120, the top surface of the chassis 100 is fixed with an arc block 130 against which the connecting plate 220 slides, and a motor 1 for driving the transmission shaft 110 to rotate is fixed inside the chassis 100.

[0033] In this embodiment, the number of teeth of the incomplete gear disk 120 is sufficient to allow the connecting shaft 210 to rotate 360 ​​degrees after the bevel gear 230 rolls over the teeth, so that the connecting plate 220 can continue to slide and stick along the surface of the arc block 130 after rotating away from the tooth position on the incomplete gear disk 120. The sliding of the connecting plate 220 on the surface of the arc block 130 can keep the receiving plate 310 stable during the material discharge and cutting process, and the motor 1 can easily rotate the transmission shaft 110 to make the multiple support rods 200 revolve around the transmission shaft 110.

[0034] Embodiment 2

[0035] On the basis of the first embodiment, the tableware bowl after trimming can be separated from the edge material.

[0036] A storage box 150 is fixed to the outer side of the chassis 100 , and a plurality of arc-shaped rods 151 are evenly fixed to the inner side of the storage box 150 .

[0037] Specifically, the support rod 200 with the receiving plate 310 rotates above the storage box 150, which will cause the trimmed edge materials and cutlery bowls to fall into the storage box 150. The edge materials will be divided into small pieces under the downward pressure and cutting of the blade 431. The small pieces of edge materials can quickly pass through the arc rods 151 and fall to the inner bottom of the storage box 150. The larger cutlery bowls will be trapped above the arc rods 151, thereby separating the cutlery bowls from the edge materials, making it convenient for users to take the cutlery bowls. The distance between two adjacent arc rods 151 is greater than the height of the cutlery bowls, which can prevent the cutlery bowls from falling to the inner bottom of the storage box 150. A vibration motor can be installed on the outside of the storage box 150 to vibrate the multiple arc rods 151 to promote the small pieces of edge materials to fall to the inner bottom of the storage box 150.

[0038] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
