TECHNICAL FIELD

[0001] The utility model belongs to mechanical technical field relates to a polyethylene sheet forming device. BACKGROUND

[0002] Polyethylene sheet mainly refers to the sheet-shaped plastic material which is made by processing based on the polymer with ethylene as the main component.

[0003] The most common polymer based on ethylene is polyethylene (PE, Polyethylene), and polyethylene sheet generally refers to the sheet-shaped product made of polyethylene.

[0004] Polyethylene sheet has a wide range of applications in packaging, agriculture, construction, industry, daily necessities, medical treatment, advertising signs and other fields due to its light weight, corrosion resistance, easy processing and low cost.

[0005] In order to obtain polyethylene sheet with a set shape, artificial cutting is usually used for corresponding operation. SUMMARY

[0006] The utility model discloses a polyethylene sheet forming device with high operation efficiency and compact structure to solve the above problems in the prior art.

[0007] The utility model discloses a polyethylene sheet forming device with high operation efficiency and compact structure to solve the above problems in the prior art.

[0008] A polyethylene sheet forming device, comprising a rack, characterized in that it further comprises a forming plate, a forming frame, a lifting assembly and a guide structure, the forming plate is fixedly connected to the middle part of the rack, the forming frame is located on the forming plate, the guide structure is located between the rack and the forming frame, the lifting assembly is located on the rack and connected with the forming frame, and the lifting assembly can make the forming frame stably translate up and down under the action of the guide structure after the lifting assembly acts.

[0009] The polyethylene sheet forming device creatively sets the guide structure between the rack and the forming frame, and can make the forming frame stably move up and down along the guide structure under the action of the lifting assembly.

[0010] In the initial state, the forming frame is located on the upper part of the forming plate.

[0011] After the polyethylene raw material to be formed is placed on the forming plate, the lifting assembly drives the forming frame to stably move down under the action of the guide structure.

[0012] Since the forming plate is located directly below the forming frame, the forming frame that moves down to the forming plate can stably cut and form the polyethylene raw material to be formed.

[0013] In the polyethylene sheet forming device, the guide structure comprises vertical guide rods on the frame and guide blocks fixed on the sides of the connecting frame. The number of the guide rods is two, the two guide rods are symmetrically arranged, and a guide groove matched with the guide blocks is arranged between the two guide rods. The guide blocks are embedded in the guide groove.

[0014] Since the guide blocks are embedded between the two adjacent guide rods, the guide blocks can stably translate along the guide rods.

[0015] In the polyethylene sheet forming device, the two parallel guide rods form a guide unit, and two guide units are arranged on the two sides of the forming frame. The number of the guide blocks is two, and the two guide blocks are arranged on the two sides of the forming frame. The guide blocks are arranged in one-to-one correspondence with the guide units.

[0016] The symmetrically arranged two guide units further improve the stability of the movement of the forming frame.

[0017] In the polyethylene sheet forming device, the lifting assembly comprises a first connecting rod and a second connecting rod. The lower end of the first connecting rod is hinged to the frame, the middle part of the second connecting rod is hinged to the guide block, the upper end of the first connecting rod is hinged to the lower end of the second connecting rod, and the upper end of the second connecting rod is an operating part for the operator to apply external force.

[0018] After the external force is applied to the operating part, the first connecting rod and the second connecting rod swing. Since the forming frame is hinged to the second connecting rod, the forming frame can stably translate up and down.

[0019] In the polyethylene sheet forming device, the number of the lifting assemblies is two, and the two lifting assemblies are symmetrically arranged on the two sides of the forming frame. The device further comprises a handle rod, and the two ends of the handle rod are connected to the upper ends of the second connecting rods of the corresponding lifting assemblies.

[0020] The handle rod has two functions:

[0021] First, it ensures that the two second connecting rods are stably connected together, improving the compactness and stability of the structure.

[0022] Second, the handle rod provides sufficient space for the operator to hold.

[0023] In the polyethylene sheet forming device, the forming plate is flat and horizontally arranged.

[0024] In the polyethylene sheet forming device, the inner cavity of the forming frame is matched with the forming plate, and the forming frame is located directly above the forming plate.

[0025] In the polyethylene sheet forming device, a machine top is arranged on the upper part of the forming frame. The machine top is fixed to the upper end of the guide rod and located directly above the forming frame.

[0026] The machine top has two functions:

[0027] First, the upper end of the guide rod is fixed to avoid the deflection of the guide rod and improve the moving stability of the forming frame.

[0028] Second, the upper part of the forming frame is covered to avoid the falling of sundries to the forming frame as much as possible.

[0029] In the above polyethylene sheet forming device, the area size of the machine top is larger than the area size of the forming frame.

[0030] Such a structure can effectively cover the forming frame.

[0031] In the above polyethylene sheet forming device, a reinforcing rod is further included, one end of the reinforcing rod is connected to the hinge joint of link rod one and link rod two in one of the lifting units, and the other end of the reinforcing rod is connected to the hinge joint of link rod one and link rod two in the other lifting unit.

[0032] The strength of the lifting assembly can be effectively improved under the action of the reinforcing rod.

[0033] Compared with the prior art, the polyethylene sheet forming device only needs to apply an external force to operate the handle rod to quickly form the polyethylene sheet, so the work efficiency is high.

[0034] At the same time, since the forming plate, the forming frame and the machine top are arranged from bottom to top, the structure is not only compact, but also can avoid the entry of sundries into the forming plate or the forming frame as much as possible, and the stability is also relatively high, which has high practical value.
